How to Use If and Only If in Mathematics

When reading about statistics and mathematics, one phrase that regularly shows up is â€Å"if and only if.† This phrase particularly appears within statements of mathematical theorems or proofs. But what, precisely, does this statement mean? What Does If and Only If Mean in Mathematics? To understand â€Å"if and only if,† we must first know what is meant by a conditional statement. A conditional statement is one that is formed from two other statements, which we will denote by P and Q. To form a conditional statement, we could say â€Å"if P then Q.† The following are examples of this kind of statement: If it is raining outside, then I take my umbrella with me on my walk.If you study hard, then you will earn an A.If n is divisible by 4, then n is divisible by 2. Converse and Conditionals Three other statements are related to any conditional statement. These are called the converse, inverse, and the contrapositive. We form these statements by changing the order of P and Q from the original conditional and inserting the word â€Å"not† for the inverse and contrapositive. We only need to consider the converse here. This statement is obtained from the original by saying â€Å"if Q then P.† Suppose we start with the conditional â€Å"if it is raining outside, then I take my umbrella with me on my walk.† The converse of this statement is â€Å"if I take my umbrella with me on my walk, then it is raining outside.† We only need to consider this example to realize that the original conditional is not logically the same as its converse. The confusion of these two statement forms is known as a converse error. One could take an umbrella on a walk even though it may not be raining outside. For another example, we consider the conditional â€Å"If a number is divisible by 4 then it is divisible by 2.† This statement is clearly true. However, this statement’s converse â€Å"If a number is divisible by 2, then it is divisible by 4† is false. We only need to look at a number such as 6. Although 2 divides this number, 4 does not. While the original statement is true, its converse is not. Biconditional This brings us to a biconditional statement, which is also known as an if and only if statement. Certain conditional statements also have converses that are true. In this case, we may form what is known as a biconditional statement. A biconditional statement has the form: †If P then Q, and if Q then P.† Since this construction is somewhat awkward, especially when P and Q are their own logical statements, we simplify the statement of a biconditional by using the phrase if and only if. Rather than say if P then Q, and if Q then P we instead say P if and only if Q. This construction eliminates some redundancy. Statistics Example For an example of the phrase â€Å"if and only if† that involves statistics, look no further than a fact concerning the sample standard deviation. The sample standard deviation of a data set is equal to zero if and only if all of the data values are identical. We break this biconditional statement into a conditional and its converse. Then we see that this statement means both of the following: If the standard deviation is zero, then all of the data values are identical.If all of the data values are identical, then the standard deviation is equal to zero. Proof of Biconditional If we are attempting to prove a biconditional, then most of the time we end up splitting it. This makes our proof have two parts. One part we prove is â€Å"if P then Q.† The other part of the proof we need is â€Å"if Q then P.† Necessary and Sufficient Conditions Biconditional statements are related to conditions that are both necessary and sufficient. Consider the statement â€Å"if today is Easter, then tomorrow is Monday.† Today being Easter is sufficient for tomorrow to be Monday, however, it is not necessary. Today could be any Sunday other than Easter, and tomorrow would still be Monday. Abbreviation The phrase â€Å"if and only if† is used commonly enough in mathematical writing that it has its own abbreviation. Sometimes the biconditional in the statement of the phrase â€Å"if and only if† is shortened to simply â€Å"iff.† Thus the statement â€Å"P if and only if Q† becomes â€Å"P iff Q.†

Steps of CART Classification and Regression Tree - 746 Words

Overview The classic CART: Classification and Regression Tree algorithm was created by Breiman. The CART method is binary recursive partitioning procedure that can be used to process both continuous and nominal attributes as targets and predictors. The binary splits are the splitting of the data represented by nodes; each node is split into two child nodes to represent the binary split on the data into two separate paths. The recursive part of CART means that any child nodes can be additionally split into more children nodes and so forth. The partitioning refers to the data being split into multiple sections along the nodes into classifications. CART Four Main Steps The CART method involves four steps: tree creation, stopping the tree creation, tree pruning, and selecting the optimal tree. Tree creation begins with a root node, which includes all the data in the training set. CART then selects the best variable to split this node into two child nodes. To find the best variable to perform this split, CART runs through all variables and their values to determine the best combination to split the node on. The process of node splitting is repeated for each created child node and continued recursively until a stopping point is reached where no further splitting can be performed. Each node within this process is assigned a predicted class based on three factors, the assumed probability of each class, a cost matrix, and the percentage of the classifier that are located in eachShow MoreRelatedCredit Evaluation Model For Banks Using Data Mining Techniques4296 Words   |  18 PagesBackground 6 2.2.1 Decision Trees 6 2.2.2 Support Vector Machine 8 2.2.3 Logistic Regression 9 2.2.4 Ensemble Methods 10 CHAPTER 3 13 METHODOLOGY AND EXPERIMENTS 13 3.1 Data Selection and Data Preprocessing 13 3.2.1 Missing Values 14 3.2.2 Data Pre-processing 14 3.3 Results 15 3.3.1 Performance Estimation 17 CHAPTER 4 20 CONCLUSION 20 REFERENCES 21 APPENDIX 22 Outputs of Models 22 â€Æ' LIST OF FIGURES Figure 1: Logistic Regression Curve 10 LIST OF TABLES Table 1: Data Set for Analysis 13 Table 2: AreaRead MoreDiffculty Level Question Questions1681 Words   |  7 Pageslearning Option 1 and 2 both Supervised Learning Supervised Learning Tree based Modelling 2 3 Decision tree  is a type of supervised learning algorithm (having a pre-defined target variable).

At that point, when it disperses the unifies to the shareholders (as profits), the shareholders need to pay assesses on the profits. Fundamentally, the same wage gets burdened twice. You can stay away from this by making the corporation a â€Å"S corporation†, which implies the corporation does not pay any government wage charge itself – rather the shareholders pay assess on their offer of the corporation’s benefits. We will write a custom essay sample on FIN Assignment or any similar topic only for you Order Now This is accessible just for corporations with few shareholders. A â€Å"sole partnership† does not by any stretch of the imagination exist. You likely mean sole proprietorship. This is the point at which somebody runs heir business without the security of a corporation, partnership or limited liability organization (LLC) or any possible legal entity that ensures the managers from being subject for the business. A â€Å"partnership† is a legal entity that gives the same assessment preferences as â€Å"S corporation† – the partnership does not pay any salary charge. Partnerships come in 2 essential structures: A â€Å"general partnership† is a manifestation of business where each one accomplice is subject for the other accomplice’s exercises identifying with the business. This is clearly not a cent alternative, since limited liability is one of the primary focal points of structuring a business entity. A â€Å"limited partnership† is the place the accomplices have â€Å"limited liability† like a corporation. An alternate manifestation of association is the LLC – this provides for you the same â€Å"limited liability† as a corporation or limited partnership, and provides for you the same tax reductions as a â€Å"S corporation† or partnership. 2.

Gates Of Ivory Essay Research Paper English free essay sample

Gates Of Ivory Essay, Research Paper English 109 Gates of Ivory In a universe surrounded by war, decease, and atrociousness, it sometimes seems as if there is nowhere positive for the characters in the Gates of Ivory by Margaret Drabble to turn. In the mist of these bad images Drabble juxtaposes a alone position into the universe of adult females? s reproduction and menses that has seldom been revealed in other novels. She shows that menses exposes feelings runing from release and authorization in Alix Bowen, to dishonor, disgust and sorrow in Mme. Savet Akrun. Drabble identifies similarities between adult females on both sides of the universe, and between reproduction and adult females battling the decease of the universe? s war. Yet throughout these difficult times and uncertainnesss, the adult females in the novel show their strength and power because they hold the key to maintaining mankind alive: reproduction. Alix? s outward looks greatly exemplify what a batch of the adult females in the novel want to be. They want to experience the control that Alix displays over her organic structure. Unfortunately for Alix, this feeling is non true on the interior. Alix holds a great trade of uncertainness and insecurity within herself. This feeling of insufficiency began in early childhood. Alix feels the demand to be a savior, a defender and an militant. She wants to make? of import? and? worthy? things, but she can neer populate up to her ain criterions. In childhood, when her pet tortoise dies, she is? panicky, [ and ] after a few yearss summoned up bravery to near the immobile shell. ? ( 194 ) . The idea of non being able to assist the tortoise, or salvage him, crushed Alix. She shows how vulnerable she is to failure, inquiry and uncertainty. If everything is non perfect, Alix? s sense of control in a state of affairs disappears. The same feelings possess Alix in her grownup life. She invariably strives for the improvement of something, peculiarly adult females? s catamenial protection, but s he feels confused and scared when she becomes even the slightest spot diffident about it. She says, ? I used to postulate that if the tampon had been invented a few thousand old ages earlier, the whole history of muliebrity would hold been different. Now I? m non so certain? ( 156 ) . Alix attests that adult females? s rights, like tampons, are on? the onward March of advancement? and are? the liberator of womankind? , but what this advancement and release will convey mystifiers Alix ( 155 ; 156 ) . The fact that there is no program on precisely how to work out the job scares Alix. Alix needs concrete programs in order to be unafraid with the thoughts, Otherwise there is no warrant of success, which terrifies Alix. But even with all the insecurities, others view Alix as a strong, liberated, independent adult female. On the interior she lacks the confidence to be self-asserting as she is on the exterior. She speaks with strong words, but does non cognize how to transport out the high outlooks she and others have for her. Drabble utilizations Alix to represent both the capable, independent side, and the unsure, dependent side of a adult female. By making this, she highlights both the power and the exposure in adult females. For much of the novel Drabble hides Liz? s womanly side from the reader. It is non until in the bosom of Southeast Asia and the centre of pandemonium that her menses reappears and sends her on a whole new journey. At first glimpse she is? appalled? and it is a? daze? ( 377 ) . This attests to her surprise and incredulity, but throughout the state of affairs her saneness remains integral. While on her long journey in hunt of female protection, Liz searches through her bag and brushs? Some safety pins, a paper cartridge holder, some wooden toothpicks. A cheque book and a sea shell. An unidentifiable white pill and a gum elastic set. [ And ] Some spots of fluff? ( 378 ) . This long list of things, among others, shows how willing and unfastened Liz allows others into her life. Liz? s journey through her bag juxtaposes her journey through Southeast Asia. There are so many things that could deflect Liz on her journey, but Liz remains focused on the hunt for Stephen. When she discovers her period, distractions loom everyplace, yet protection remains in the head of her head. She encounters a whirlwind of emotions and hemorrhage controls her ideas, she can make nil else. Liz focuses her attempts to one cause and they remain at that place. This is a strength Liz uses to keep her saneness in such helter-skelter conditions. Even with the most improbable of things happening, Liz keeps her saneness and control integral and perseveres through the state of affairss. The state of affairs does non do her paranoiac, it does non even seem to phase her. Drabble utilizations Liz to demo the capacity of adult females and their finding through seeking times. Even with the biggest of distractions, adult females remain focussed and capable of anything. Unlike Alix Bowen or Liz Headeland, Mme. Savet Akrun feels non merely plume about her menses, but besides shame and sorrow. Both she and the adult females in her small town have had really dramatic experiences with their rhythms, and the poorness and the force merely aid to stress the jobs that they have had. The adult females in her small town have had to go really in melody with their organic structures and their rhythms because of the jobs they have with happening protection. Unfortunately, as Mme. Akrun says, this has led many adult females to? take to discontinue to flow? ( 153 ) . Drabble shows that it is a sense of depression, the adult females can non expect the actions of their organic structures, when they bleed, they can non protect themselves, so they will themselves into non shed blooding. Drabble illustrates that Mme. Akrun and the adult females of the small town position menses as something that can non be taken by the wars and the force of the universe around them. It must be protected, even if that means halting it for a period of clip. Yet when the menses does get down up once more, the adult females haste and reproduce every bit rapidly as possible, seeking to battle the loss of lives in the war. The protection that these adult females have for their generative system shows when Drabble uses a quotation mark that a nurse gave while in the small town: ? Every nurse? s fright was B eing taken captive and non holding any Tampax. You couldn? t count on being in the jungle and utilizing a foliage, because the jungle was defoliated. We were ever told to hold a bag packed, if we got overrun, we? d be lifted out. That was a carbon black of *censored* . I found out subsequently that they neer had any such emptying program. If we got overrun, it was merely tough breasts. In any instance, we all packed the same things. We packed money, a camera and we packed Tampax. My flax jacket was so full of Tampax that nil could hold penetrated it. ? Nurse, quoted in Nam, Mark Baker ( 159 ) In this transition Drabble shows precisely how of import menses is to adult females. Womans chose to convey Tampax over any other ownerships. Attack and invasion may take their lives, yet all they can believe about is what they will make to protect themselves when their following rhythm comes along. The nurse utilizations harsh and straightforward words. She does non keep back her feelings. She has seen the horrors and the play and the desperation in the small town, and she will non sugarcoat coat it. The same kinds of feelings possess Mme. Akrun. She has seen it all, and she refuses to dissemble it and sugarcoat coat it for others. She lives world to the fullest sense. Like the nurse, her words are non equivocal, they are certain. Both adult females realize they can merely number on themselves, and this gives a sense of release every bit good as resentment. The nurse in the transition uses phrases like? tough breasts? and? carbon black of *censored* ? to state the universe that she knows that life should non hold to be this manner, but it is and she has come to footings with it. It is all about endurance to her now. Although adult females wish they could be more protected and sheltered, they besides realize the strength and power they possess with this control, and do non desire to blow it. Even if all else fails, adult females hold the power to do a restart, a metempsychosis. It is particularly illustrated in the line? nil could hold penetrated it. ? Nothing can perforate the control these adult females have over their reproduction systems. Even through all the shame and the uncertainness, they feel they still possess control. It is the one thing in their lives that can be counted on. If it leaves, finally it will return, and no male can hold the power that they have in this country. ? The midst dark metallic urarthritiss of blood? will be the savior ( 153 ) . The enunciation that Drabble utilizations here attests to the strength of menses. It is impenetrable : it is strong and will non melt. The most of import thing that Drabble shows is the doggedness of adult females. She shows that even in the roughest times the adult females will last and maintain control. Unlike many of the adult females in the novel, Hattie Osborn sees her generative system in both a sexual and a functional manner. She views menses with a lighter attack. Hattie Osborn is most likely the most sexually provocative adult female in the novel. She openly uses her gender as a arm and a plaything. Her menses and generative system are all a gag and a game for her until Aaron Headeland comes along. Hattie alterations when this occurs, she goes from a carefree, sexually explosive being into a lovingness and concerned adult female with kid. Drabble reveals her in the beginning as holding no declinations about non holding kids: she has wholly put aside that portion of her. Then subsequently in the novel when she finds out she could be pregnant she is non in the least bit disquieted or concerned in a bad manner, she is happy. She can experience the alterations inside her? she quickens, she feels herself quicken, as the little cells bunch? and she is wholly in melody with the moti ons in her organic structure. Drabble creates a sense of repose and control in Hattie even though it is a really unsure minute. She is aroused and renewed. She is non scared of the reaction of her friend Liz, she is certain of herself. She has a sense of security that everything will turn out good somehow. Hattie had ever been the independent one, the 1 with no demand for any one else, and now all of a sudden she feels a great fond regard to Aaron. But even with this great fond regard she realizes that what is approximately to go on is particular and she can make it herself with no 1? s aid. She says? When Aaron turns to dust and ashes in my sight, and I in his, there? ll be a babe? ( 319 ) . This shows that Hattie does recognize the power she has as a adult female. She sees that there is no turning back and that what happens to her babe has nil to make with Aaron, it is all her determination now. She repeats the quotation mark? Eggs, blood and the Moon? twice in the novel ( 158, 41 6 ) . She understands the rhythm of her menses and the rhythm of her life. She is the 1 that is able to truly come to footings with her generative rhythm. She has lived the life of a free willed adult female, and now she is sing the other side of muliebrity. Drabble shows Hattie as one of the most dynamic adult females in the book. She is the lone adult female that goes through all the rhythms of muliebrity during the novel, she is the efficaciously shows the versatility and changes a adult female can travel through, and most surprisingly she stays strong and in control throughout. Drabble exemplifies Hattie? s confidence to be what all adult females should hold, no uncertainty in themselves. Drabble? s portraiture of adult females in the novel illustrates her ideas on adult females good. She shows that a adult female? s life is full of turns and bends and uncertainnesss. Throughout all the bends that each adult female had in so novel, they each came out with their caputs held high and strong. Drabble portrayed them as vulnerable and dependent in many countries, in fact in most countries. The lone portion of life a adult female had a existent clasp on was menses and reproduction, and even this was unsure at parts. Drabble seemed to be directing the message that although menses and reproduction were really independent and commanding on their ain, that adult females were the lone 1s in society that had a opportunity to command it, which gave them a batch of power. Womans hold the key to the endurance of world, and that is a great power and duty. Drabble efficaciously shows in this fresh how difficult that committedness can be.

Marxist Theory Essays - Characters In Macbeth,

Marxist Theory The Marxist literary theory is based on the idealistic notion of socialism, therefore, economics is at the center of Marxism. Everyone is equal and nobody has more money than anyone else. The Marxist theory says that all actions follow a logical, scientific pattern. That statement is the complete opposite from the world Macbeth lived in where status was gained by murder, and immortality was gained by dying. Social progress is also a key aspect of Marxism. It involves the advancement of the whole community not just one person, to the point where everyone is equal. Marxism also encourages the formation of a middle class and equality among all the people of the community. From a Marxist point of view, materialism is seen as a step backwards because the people who feel the need to accumulate wealth and possessions do not understand their responsibility to their fellow folk. Macbeth is lacking self-respect and confidence by conforming to the wishes and demands of those around him such as the witches and most of all Lady Macbeth. This is a form of social regression, which is a point of consistency in Macbeth's character. Duncan was one of the most beloved kings and by Macbeth killing Duncan he creates countrywide corruption. By killing Duncan he not only destroys a country, he destroys himself. The gradual deterioration of Macbeth's sanity is matched with Macbeth's loyalty to the King. After his newfound power in the Thane of Cawdor his loyalty and self-respect take a drastic plunge. As Lady Macbeth slowly influences him to kill Duncan, Macbeth becomes more and more committed to the idea of power. Lady Macbeth keeps on wanting more and more and as Macbeth slowly transforms into her he becomes as greedy and materialistic as her. Marxism is against materialism because if one hoards all the goods than there can be no equality within the community. Materialis m in any form does not serve the common good of the society. Duncan's murder is a slow process because it his first and he contemplates the severity and consequences of this murder more so than any to follow. By killing Duncan Macbeth killed God's divine presence on earth and by killing Macbeth, MacDuff kills the devil's presence on earth. Before Macbeth kills the king he contemplates the consequences of the crime. Macbeth, at this point, is not planning on killing Duncan. It is in more of a hypothetical context. ?But in these cases we still have judgement here; that we but teach bloody instructions, which, being taught return to plague th' inventor.? -- Macbeth Act I vii lines 7-10. Macbeth knows that the action of this crime will haunt him and eventually ruin him. If he kills Duncan someone will ultimately take his life. He realizes the consequences of his actions and knows that eventually they will come back to haunt him and possibly have the same thing done to him. He does not think that he will ever actually kill the king, only for the king. In the war when Macbeth served loyally and killed for the country and everyone in it he was fitting in with the ideas of Marxism. By serving everyone Macbeth along with everyone else was progressing. But when he kills Duncan he kills for purely selfish reasons. ?I am afraid to think what I have done; Look on't again I dare not.? Macbeth is completely terrified and beside himself at what he has done. He already wants to block it out of his memory. This is just the beginning of the journey he is going to take towards complete anti-Marxist behavior. Banquo's murder shows what level Macbeth allowed himself to stoop to. He had his best friend murdered in an effort to cover up his mistake. This is the perfect example of how power in the wrong hands can so quickly go awry. ?So he is mine (enemy), and in such bloody distance that every minute of my his being thrusts against my near'st of life: and though I could with barefaced power sweep him from my sight and bid my will avouch it (III,i ll. 16-20) Macbeth declares to the murderers while convincing them that Banquo is the enemy, that

The effect of temperature on a squash ball Essays

The effect of temperature on a squash ball Essays The effect of temperature on a squash ball Paper The effect of temperature on a squash ball Paper I did a preliminary experiment to see if my method would work and if there were any problems with the way I will conduct my experiment. Preliminary Results Temperature (i C) Distanced Bounced (Cm) 90 81 40 68 0 20 Factors affecting my experiment If I use different squash balls of different elasticity it will affect the bounciness of the ball.   If I use different surfaces for the ball to bounce on, I may get different results because different surfaces absorb energy better than others.   If the temperature increases, then in theory the bounciness should increase. This is because the atoms have more energy so theyll move faster; theyll have more kinetic energy inside the ball. This creates more pressure making the ball harder and bouncier. I increase the height I drop the ball from, the gravitational potential energy increases. The ball will have more energy so the bounciness increases. This formula shows how to work out the amount of energy the ball has at each height: Gravitational Potential Energy=Mass x Gravitational Strength (10N) x Height   The older the ball is, the less elastic it is. Obtaining Evidence i Temperature of the ball Distanced Bounced (Cm) 1st Test 2nd Test 3rd Test Mean Rounded Mean have carried out my plan and have used my equipment precisely to observe and measure the rate of reaction to a good level of accuracy. I have taken a sufficient number of accurate results and have recorded them in a table. I dont need to repeat any readings as none of them look to be anomalous. I made no changes to my plan but carried out a preliminary to make sure I wouldnt have to make any changes half way through the experiment. I made sure I was wearing safety goggles while I was heating the water with a Bunsen burner to protect my eyes. I stood up throughout the experiment to lower the risk of injury. When I took the squash ball out of the beaker I used tongs so I didnt burn my hands. Analysing Evidence. Ive plotted my results onto a line graph and a clear pattern is seen. As the temperature of the ball is increased, the distance the ball bounces is also increased. The squash ball starts to bounce higher and higher after every 10 degrees, but towards the end the distance of the ball doesnt increase as much than the first few points on the graph. This can be shown by looking at the gradient at the beginning of the graph and at the end. At the beginning, the gradient is 1. 23, towards the end the gradient is 0. 44, this shows that its decreased which means theres less difference between the results towards the end. This means that after a while the ball isnt affected as much by temperature. In my investigation I found out that temperature does affect the bounciness of the squash ball, like I said in my prediction. I thought this would happen because as the temperature increases the pressure inside also increases making the ball harder and bouncier. The pressure increases because the atoms are moving around with more force and faster because they have more energy. My results back this up. I dont have any extreme anomalies but my second point on the graph is a bit anomalous. This could be or a number of reasons due to human error. For example I might not have seen the distance the ball bounced correctly, or I might have dropped the ball a little bit lower than the other times. Evaluation The evidence I obtained was good for the simplicity of my investigation. I think the way in which my investigation was carried out was effective but could have been more accurate. For example, I carried out all of it. If I used machines or computers it would have been a lot more accurate. If I had the equipment to this I would have a machine drop the squash ball from an exact point and use either or video camera or light motion sensor to get the exact measurement of the bounce. This would be a lot more accurate than my own eyesight. But saying that, my results were very accurate without machines and I can see this by how Ive plotted them on the graph. They were easily accurate enough to make a firm conclusion on that increasing the temperature increases the bounciness of the ball. There werent any results that didnt fit into the main pattern. I think this is because I took great care while carrying out the experiment. There are many other experiments I could do to extend the work Ive done. For example I could look at all the other factors that affect the bounciness which I mentioned in my plan.

A Study on the Effects of Alcohol on Human Health Effects of alcohol on human health Alcohol consumption is a common practice at various gatherings and parties in different parts of the world. Nonetheless, alcohol consumption can have a different impact on human health and can lead to negative social consequences due to addictive, toxic and addictive properties. So we will talk about drinking in this essay, and its main purpose is to discuss its causes and consequences. When we discuss the causes of drinking, we can say that society is the main engine in this process. Alcohol is generally accepted as an integral part of any company. People think alcohol makes you excited, energized, improves mood and health, makes conversation more vivid and fun, but its just a temporary effect. Some use it as a sort of solution to the problem, but can not solve it and cause depression. By observing the effects of alcohol on human health, it can be said that alcohol can cause health effects such as mental illness as well as social illnesses. Today, alcohol abuse is a major problem in modern society because it affects all human organs and alcohol intake causes skin dehydration. This is because skin cells lose essential moisture and valuable minerals. In addition to the chronic illnesses that occur according to the age of the person consuming large quantities of alcohol, drinking is associated with increased risk of acute health conditions such as trauma, including injuries from road traffic accidents. So, to summarize the previous statement, we can say that the need for alcohol is not part of the natural life of human needs, such as oxygen, the need for food and water, and that alcohol itself is not motivated by humans. Young people are beginning to use alcohol as an obvious attempt to follow fashion, but the situation has changed dramatically and does not stop. I think society should fight this phenomenon and popularize a healthy lifestyle, but if everyone wants to control drinking and stop it, the problem will eventually disappear

Checkout paper # 3 - Essay Example I love my dog because she is a good companion but of late she has been giving me problems. She messes around especially the carpet and my neighbors often complain about her. At one time she was injured by my neighbor’s child. I can see that you are angry for your dog because she makes the carpet dirty. However, I have done some researches and discovered that pet lovers ought to be patient with their pets since they have a habit of messing around in most cases. I then posed this question: What do you think must be done then? However, I realised that I had blundered by asking this question since the client was seeking help in order to address the problem. Therefore, for self disclosure, I sympathized with the client and indicated that as human beings, we always feel the same way when we clean the mess by the dogs. I paraphrased my question so that the customer could shed more light about her feelings towards this dog. She responded by saying: From this response, I realised that my customer was mainly concerned with finding a lasting solution to this problem rather than disposing the dog. I responded to the client by indicating that a dog can be trained but this can be done over time. This response gave my client renewed hope about changing the behaviour of her dog. I used strategies such as reflection, summarization paraphrasing as well as clarification in carrying out this task. I have learnt a lot of new things in as far as interviewing is concerned. In terms of non verbal communication, I maintained a steady eye contact and I would also use some facial expressions when talking to my client. I also listened very carefully to her as she spoke. However, one weakness I have noted about my interviewing technique is that some of my questions were too direct. For instance, I said: â€Å"What do you think should be done?† I do not think that this question should be asked to the client who has come for help. Essentially, the interviewer should suggest

GM Strategy Essay Example | Topics and Well Written Essays - 3000 words

GM Strategy - Essay Example The emergency of the low cost Japanese made cars compounded the difficult situation of competition which was already taking a toll on General Motors. Various global changes also took place in the motor industry such as new technological innovations, new marketing strategies that specifically focused on meeting the interests of the customers among other factors. In response, GM invested heavily in its endeavour to keep pace with these global changes. However, the major setback that hampered its efforts was the aspect of bureaucracy resulting from hundreds of divisions within the company which made it difficult to have focused, well coordinated operation systems. During its heydays, GM used to pay very high benefit packages since it was very profitable especially during the mid 1970s when it dominated the US markets. However, due to changing global trends especially the emergency and ultimate dominance of other rival competitors such as Toyota and Nissan, GM has lost some of its competitive advantages to these rivals. Compared to Toyota, GM pays as much as $35 for pension benefits whilst Toyota pays around $11, which gives it a cost advantage of about $1500 a car contrary to GM’s position. GM has to charge less premium than its strongest competitors hence it sells its vehicles at a loss. GM is now in a predicament of continuing paying high benefits to its workers against the backdrop of losses owing to the union laws that are a bit stringent such that it cannot abruptly cut these benefits to meet the global trends nor simply layoff some of the workers. It seems GM’s revenues are higher than those of Toyota but at the end of the day Toyota has higher earnings as a result of the fact that GM spends more money on operating costs and other expenses. GM makes more cars than it can profitably sell which means that it would end up selling at a loss. In fact it is no longer getting profits from its

Challenges in the Business Environment Essay Example for Free

Challenges in the Business Environment Essay There has been no change to Apple Code of Conduct policy since 2014 when Apple started taking previous audit scores into consideration and conduct detailed risk assessments with suppliers who had not been audited in the past before awarding the new business. In 2014, we reviewed 459 suppliers, and factored their responsibility performance into our decisions. This engagement has allowed Apple to address over 700 findings related to labor standards, worker safety, permits, environmental hazards, and chemical management before production began (Apple – 2014 Supplier Code of Conduct). Apple has made significant progress, gaps still exist, and there is more work to do. Apple knows that workers are counting on them and they will not stop until every person in their supply chain is treated with the respect and dignity they deserve (Apple Supplier Responsibility 2015 Progress Report). Apple believes that it is not enough to just set high standards they must work every day to make sure they’re upheld. Apple Supplier Code of Conduct is among the toughest in the industry. To track working conditions at suppliers’ facilities, we conduct regular, in-person audits deep into the supply chain. Audits remain essential to Apple work, but they’re only the beginning. Apple reports monthly on working hours for over one million workers with hopes that their openness will inspire other companies. But more important, Apple believe the feedback that transparency invites makes us even better (Apple Supplier Responsibility 2015 Progress Report). Apple’s suppliers are required to provide safe working conditions, treat workers with dignity and respect, act fairly and ethically, and use environmentally responsible practices wherever they make products or perform services for Apple. Apple requires its suppliers to operate in accordance with the principles in this Apple Supplier Code of  Conduct (â€Å"Code†) and in full compliance with all applicable laws and regulations. This Code goes beyond mere compliance with the law by drawing upon internationally recognized standards to advance social and environmental responsibility. This Code outlines Apple’s expectations for Supplier conduct regarding labor and human rights, health and safety, environmental protection, ethics, and management practices. Apple assesses its suppliers’ compliance with this Code, and any violations of this Code may jeopardize the supplier’s business relationship with Apple, up to and including termination. This Code applies to Apple suppliers and their subsidiaries, affiliates, and subcontractors (each a â€Å"Supplier†) providing goods or services to Apple, or for use in or with Apple products (Apple – 2014 Supplier Code of Conduct). To show that Apple believes that it is not enough to just set high standards and that they must work every day to make sure they’re upheld. In 2014, over 2.3 million workers were trained on Apple’s Co de and their rights. Apple invested millions of dollars to expand our Supplier Employee Education and Development (SEED) program since it began. SEED now totals 48 classrooms in 23 facilities equipped with iMac computers, iPad devices, education software, video conferencing systems, and more. To make sure the standards were upheld Apple performed 633 audits covering over 1.6 million workers in 2014. Apple also audited suppliers in 19 countries and calls were made to 30,000 workers to make sure their rights were being upheld (Apple – 2014 Supplier Code of Conduct). Apple Suppliers Understanding of Their Standards, Responsibilities, and Company Relationship Apple is proud of the strong relationships they have built with their suppliers, many of whom have been working with them for years. Apple periodically reviews their relationships and adds new suppliers as needed. Apple requires each of its suppliers to meet the highest standards for all goods and services. Our requirements include a commitment to rigorous quality assurance. In addition, suppliers must be committed, as we are, to ensuring the highest standards of soci al responsibility. The ideal suppliers are those who understand our culture and expectations. We value suppliers who take the time to learn about and understand our business and who look for ways to add value. These suppliers know the importance of making and meeting commitments and delivering the highest quality goods and services (Apple Apple and Procurement). Apple business environment is  competitive and fast-paced. Apple suppliers must understand this dynamic and be agile and flexible in responding to changing business conditions. All over the world, people are building Apple products and Apple has a responsibility to make sure that each person is treated with dignity and respect. It’s a massive challenge where Apple work is never done, but each year they implement meaningful, lasting changes across their supply chain. Because of this around the globe, Apple employees are united in bringing equality, human rights, and respect for the environment to the deepest layers of their supply chain. Apple goes deep into their supply chain to enforce their social and environmental standards by empowering workers through education, demanding that suppliers treat workers fairly and ethically at all times, having safe and healthy facilities, and hold their products and processes to the highest environmental standards (Apple Supplier Responsibility 2015 Progress Report). Apple believes that in order to make impactful changes across their supply chain, it’s important to understand firsthand what’s happening inside their suppliers’ facilities. That’s why they don’t simply employ and review audits from behind a desk in Cupertino. Instead, they directly gauge how their supplier facilities are doing by regularly visiting and partnering with their suppliers around the world, so when they discover a problem, they can work together to get it fixed (Apple – Accountability). To make sure the standards are understood and upheld Apple performed 633 audi ts covering over 1.6 million workers. Apple also audited suppliers in 19 countries and calls 30,000 workers to make sure their rights are being upheld. Every audit is led by an Apple auditor and supported by local third-party auditors. These third parties are experts in their fields and all have been trained to use our detailed auditing protocols. During each audit, Apple grade suppliers on more than 100 data points corresponding to each category of our Supplier Code of Conduct (Apple – Accountability). Apple auditors are highly skilled at identifying when suppliers are covering up information. Apple audits are proven to improve supplier compliance. Each year we review and raise our already strict requirements, and suppliers continue to meet our increasingly stringent standards. In 2014, facilities audited two times scored 25 percent higher than those facilities with first-time audits. Facilities audited three times or more scored 31 percent higher than facilities audited  for the first time (Apple – Accountability). In addition to these regular, prescheduled audits, Apple randomly select facilities to audit unannoun ced. These surprise audits help ensure that our suppliers continue to meet our standards at all times not just during scheduled visits. Apple conducted 40 surprise audits in 2014, where their team visited suppliers on the spot and inspected the facility within hours. After the audit Apple conducts physical inspections, reviews documents, and interviews workers in their native languages, without their managers present. Afterward, workers are given a phone number, so they have the opportunity to securely and confidentially provide additional feedback about a facility to our team, including anything they consider to be unethical behavior. Apple encourages workers to report any retaliation to us, and we follow up with all suppliers to address each reported issue (Apple – Accountability). Inclusion these audits, code of conduct, and standards give Apple suppliers the understanding of what it means to be part of the company. Reference Apple Accountability. (2015, January 1).

Invisble Man :: essays research papers

Invisible Man – Part II by Ralph Ellison Before being expelled Dr. Beldsoe tries to make a deal with the narrator. He says â€Å"if you can get a well paying job in New York, you can come back to the college†(pg. 101). The narrator agrees to this, and Dr. Bledsoe gives him several letters of recommendation and sends him on his way. When the narrator gets to New York, the son of Mr. Emerson, one of the people Dr. Bledsoe wrote a letter to, tries to tell the narrator about the tyranny that he is being exploited by. But the narrator refuses to listen until he is shown the letter that Dr. Bledsoe wrote. He discovers that all the letters of recommendation are phony and that Dr. Bledsoe never actually intended for him to be able to re-enroll in the college. This realization finally causes the narrator to become at least partially disillusioned. Because of this, he decides to forget about the college and takes a job at a paint factory. At the paint factory he begins working as an assistant to Lucius Brockway, an old black man that works the machines in the basement. Brockway explains to the narrator that it is the people who work the machines, and not the machines themselves that are responsible for the success of the company. He tells him, "We the machines inside the machine." The narrator, however, fails to grasp the broader meaning of this quote. Afterwards, Brockway tells the narrator that a union has been trying to get the employee’s higher wages and that if that happened the paint factory could go under. When Brockway discovers that the narrator went to a union meeting, he attacks the narrator. While they are fighting, the machinery goes haywire and when the narrator tries to fix it, it explodes, knocking him unconscious. The narrator wakes up in the factory hospital. At first he thinks they are going to help him-that they are going to try and relieve his pain and suffering. But again, this i s only a naive illusion. Instead, he becomes a guinea pig for experimental electroshock therapy. The electroshock therapy causes him to forget who he is. This is symbolic of how his continual exploitation has been robbing him of identity. After he recovers from the amnesia and leaves the hospital, he realizes that he is no longer afraid of important men since he no longer expects anything from them.

Cell Phones Advantages&Disadvantages Essay

1.0 Introduction When I have been on different school placements during my time at the College there has always been one thing I have paid more attention to and noticed in every school. This situation is a very common thing among students in Malaysia and also occurs among people who normally use more than one language. This phenomenon is called code-switching and usually happened in bilingual societies. What is code-switching? It is when a person mixes two languages in a single sentence or a conversation. This issue was ordinary to take place in Malaysian students which is learning more than one language. Our country students usually learned more than three language likes national language, mother language and etc. Our ministry of education set English as a second language in Malaysia, so Malaysian English Language Instructors and ESL (English as second Language) requires learners tend to use more than one code of language in the context of formal classroom. Now, we wants to discuss the factors that cause ESL learners to code switch and how to overcome it. 2.0 Main Body 2.1 Feel More Comfortable, Environment, Lack of Confidence The first factors it cause students cannot switching code immediately because they not usual to use English and also feel custom and more comfortable to use their own language. They prefer to use their own language because it is more smoothed and easy communicate with their friend. Besides that, they also did not have a good environment or social to speak English. Take one example, we was grow in a family which does not often speak English and we just only use our mother language to communicate with our family’s in home, that is a big problem for us to learn and speak English properly. The problem will cause the students lack of confidence to speak English because they do not have basic for speak to other people. Last but not least, they also will feel shy to use English because they are afraid of speaking mistakes. 2.2 Lack of Motivation, Lack of Interest, Lack of Enforcement Furthermore, they also lack of motivation because they do not get any courage from their friend or family. When students do not have enough vocabulary word they  cannot speak any perfects English. If they cannot speak English properly, they will give their friend laugh and it will causes they do not have more interest in English. Besides that, they will also give up to learn English and also will drop out of study. Motivation may be expect to improve when class take into account students likes in teaching style and lesson material. Additionally, parents did not enforce their children to speak and learn English in home. Parents also lack of accompany with their children to teach them important of English or another language in the whole world even tourism and doing business. 2.3 Watch more English videos, more interaction, talk with others race After the factors let us talk about solutions to overcome the problem students who are face it. Lecturers can takes some video from youtube or google to share with students but ensure the video can help students to improve their English. They can also listen music English or see an English movie to increase their listen and speaking skill. We must let students have more interaction and practice among them when during lesson. Lecturers should break them into different group with different language or country to get more chance to be in touch with English in class. 2.4 Join the activity can improve English, Attended to tuition, Penalty The parents need to speak with them in English and without home language at home to improve their basic in speaking. Parents also can send them to counselling or campaign for training them to use English in social life. Students must me hardworking and go to a place which availability of additional resources or knowledge to increase their vocabulary. To give those students cannot handle the basics English parents should force them to attend tuition class. When students in the school or college, lecturers must be ensure students are in the English speaking zone to communicate with their friend without other language. Last but not least, if those students who are not follow the rules must give a heavy penalty to let them remember and would not do a same mistake against. 3.0 Recommendation and Conclusion The use of mother language is not conclusively a threat to English as a language or a subject at school. In school or college lecturers should be concern about students have the ability to differentiate the two language and separate them in formal and non-formal communications in class.  Therefore, poor performance in English cannot blame on home language, but a person’s background. In my view educators should take the responsibility and teach suitable things to enable the primary level students learn in English. Its can make them understanding in a better command of English. 4.0 REFERENCES 1) Jtonec. (2012).

Question 2 1.0 Introduction In this global computer science and technology, who does not have a cell phone these days? Even a child in primary school some of their parents also will give them a phone to them for easily to stay contact with parents. However in this era of technology, a cell phone most amazing things is that they are no longer just used for calling or texting. Actually, a cell phone is not just only a tool for communicate with family and it is also a tool for multimedia such as smartphones. The smartphones can use in multimedia likes games, pictures, songs and it will bring out many advantages and disadvantages for us so with this mind. Hence, should students be permitted to use cell phones in school has become a hot topic of discussion among individual. Thus, let us discuss and debate about this topic. 2.0 Main Body 2.1 Access Information, Useful Application Firstly, it goes without saying that the advantages of cell phones is it can help students to overcome some of their academic problems. This is due to the reason that cell phones allow them to download some useful software such as dictionary. When they cannot understand what their lectures teaching about due to the vocabulary, they can find the meaning of the vocabulary and try to translate it to their own language by using the dictionary software  so that they will manage to understand what their lectures teaching about. In addition, they can also access ‘google’ to find the materials which they need. This is because internets have a pool of information to provide the information that they acquire. On the other hand, the student parents can also check their children whereabouts by using a phone. Besides that, the smartphone also has a lot of function such as calendar, calculator, maps finder and many technology software. I can take an example that I will use software to supervise my homework and revision to ensure that I will not waste the precious time. 2.2 Replace Pen and Paper, Use To Memory, E-learning Apart from that, using cell phones to do home works or assignments can replace the pen and reduce the paper so that this will help to reduce deforestation as well as keep away from greenhouse effect. The cell phones can also become a â€Å"memory card†, when the student insufficient time to write down all the points that the lecturers given or he or she absents the lessons, they can just take a picture and do revision at home. Furthermore, they still can take out these pictures to revise before the examination. In this way it is killing two birds with one stone a stone. Additionally, they can use for E-learning in internet by using a cell phone with their friends and lectures to discuss homework or which are they do not understand in the lesson. 2.3 Distraction Class, Cheating, Bullying Every coin has two sides, cell phone also bring some disadvantages to us. Let us discuss the disadvantages of a cell phone right now. The cell phones also bring out many troubles to students like distract the lecturer and all their friends. The meaning distract is stand for while lecturer teaching in the class the students who play games and the worst is cell phones ringing will disturb the whole class force to stop the class. After that, the students will also laugh at which classmates those who are not using the latest phone. They cannot understand their parents work hard also unable to buy a latest phone to them because new phones price is too expensive and even run up to two thousand. 2.4 Annoying Lecturers, Health Hazard, Safety of Students When lecturers is teaching in the class, the students which is mischievous will take the lecturer funny picture and upload to the social network to annoying their lecturer. These types of students do not have manners because they did not give any respect to their lecturer. England scientist investigate point out if each people using cell phones in one day more than 2 hours, they will get health hazard like shortsighted, radiation, skin cancer. So, if students bring cell phones to school they will get more times to be in touch with the disease above. Beside, students can keep play their phones and did not pay attention when they go downstairs or cross the road. It is very dangerous actions and do not behave their self and their family. 3.0 Recommendation and Conclusion In the last, students bring cell phones to school have both of advantages and disadvantages but they should know how to use the cell phones in the place is correct. We can come to a conclusion that although mobile phones have their weak points, they are very useful when they are necessary. Students are the decision makers. Therefore, we can choose which are good and bad. According to my opinion cell phones are very useful things if we use them in a proper way in the school it may help students solve many problems. 4.0 REFERENCES 1) RaulBarrera. (2012).

How is the HTS regulated? By local, state, and federal government agencies. The federal government established the National Highway Safety Act. All agencies enforce the following guidelines set forth in this act. 1- Vehicle code – the laws that have been passed – Assure that these laws are obeyed 3- Motor vehicle departments set the rules to assure that driver and vehicle standards are met 4- Rules for the courts to go by for guilty or innocent 5- Engineers plan, build, and maintain roadways The driving task This involves all of the social, physical and mental skills required to drive.

ATTITUDE Your attitude toward driving as well as life affects your willingness to develop the habits needed to be a safe driver. ROAD RAGE What is it and what causes it Breakdowns in the HTS. These occur when any part of the HTS does not work well. Collision – occurs when a vehicle has a problem and hits another object. Which is more correct? Collision or Accident? An accident is something that happens by chance†¦ a collision is something th at has a predictable cause. The most common cause for a collision is†¦DRIVER ERROR (P. 9) Causes of deaths: A major cause of vehicle deaths is†¦ LACK OF EXPERENCE Social and Economical Loss Collisions cause social and economical loss by: – property damages (p10) – time away from work or school – medical fees – insurance premiums Your financial responsibilities. – vehicle related costs: fuel, maintaince, and insurance. – Any damage that you cause while driving.

IMPLIED CONSENT PROGRAM (LAW) When you sign your license in SC you give an officer the right to test your blood alcohol content (BAC). If you refuse the test you will lose your driving privilege. WHY DO YOU TAKE A DRIVER’S EDUCATION COURSE Chapter 2 Signs, Signals, and Roadway Markings Traffic Signs There are three types 1- Regulatory – control traffic flow 2- Warning – alerts of a possible hazard or road condition 3- Guide – give direction Stop Signs This is the only red, octagon sign we have.You must come to a COMPLETE(full) stop at this sign. Four-way stops – rules you need to follow 1- The first one stopped gets to go first 2- If 2 cars get there at the same time, the car on the right gets to go first 3- If 2 cars get there together and are across from each other, the car traveling straight goes first 4- If 3 or 4 cars get there together, one needs to enter the intersection to show intent, but with caution 5- ALWAYS CHECK THE INTERSECTION BEFORE ENTERING IT Yield Signs This is the upside down triangle – red and whiteYou must allow others in the intersection or approaching the intersection to go first before you. This is called giving the right of way. Right of way is given, not taken. p. 2 Speed Limit Signs These are white, mostly rectangles, with black writing. They indicate what the safest maximum speed for that roadway in IDEAL conditions. Basic Speed Laws state that when conditions are not IDEAL you must not travel faster than what is safe for the conditions. Advisory Speed Limits are set for certain sections of the roadway. Once you have cleared that section you may resume the posted speed limit.Warning Signs These are yellow signs that warn you of upcoming conditions in the roadway. Most are diamond shaped with black symbols. School Signs indicate where school zones and crossings are. They are shaped like a house (pentagon). No Passing Signs are placed before where the roadway begins to narrow. Construction Signs indicate where construction zones are. They are orange signs with blac k symbols and letters. Railroad Signs – There are two types of railroad signs; a yellow circle with a black â€Å"X† and two â€Å"R†s also black and a white cross with black railroad crossing letters.The yellow sign indicates you are approaching a railroad crossing and the white â€Å"X† indicates where the railroad tracks begin. p. 3 Guide Signs These signs mark routes, intersections, service areas, and other points of interest. Route signs are local, state, U. S. and interstate markers. US = white shield on a black sign with black #s State = white square with black #s and letters Interstate = red and blue shield with white letters and #s Even #s = east and west Odd #s = north and south 3 numbered route that begins with an odd # goes into a city 3 numbered route that begins with an even # goes round a city (beltway) Other guide signs are: Green = give information on destinations and distances Blue = roadway service information (hospital â€Å"H†) Brown = recreation areas and points of interest TRAFFIC SIGNALS Include traffic lights, arrows, flashing signals, lane signals, and pedestrian signals. Traffic lights are red, green, and yellow. Red = stop Green = proceed through the intersection if it is clear to do so. Yellow = slow and stop if you can do so safely. Right turn on red and left turn on red. When can you do it. p. 4 Flashing signals: Red – treat it as a stop signYellow – treat it as a yield sign Arrows tell you the direction in which your lane must travel. Green = proceed if it is clear to do so Yellow = yield and stop if possible Red = Stop only in that direction Lane Signals – these lights will switch the direction of traffic in a certain lane to control the need for traffic flow. Pedestrian Signals – allow walkers to cross at an intersection safely. â€Å"walk† â€Å"don’t walk† When a police officer is standing in the intersection, their directions overrule any si gnal. Roadway markings These are yellow or white lines as well as arrows, stop lines and crossings.Broken Yellow Line = separates two-way traffic and you may pass when it is clear to do so. Solid Yellow Lines = separate two-way traffic and you are not allowed to pass. Shared Turn Lanes = you may enter and wait until it is clear before you turn left across traffic. Broken White Line = separates traffic traveling the same direction. You may pass if it is clear to do so. Solid White Line = indicates the right side of the road and should not be crossed. White Arrows = indicate which direction you are allowed to travel in that particular lane. Rumble Strips — Lane Reflectors – Yellow Curb Markings Chapter 3 Basic Vehicle ControlsINSTRUMENT PANEL Speedometer – tells you how fast you are going Tachometer – tells you how many revolutions your engine makes in one minute Odometer – tells you how far your car has traveled in its lifetime Fuel Gauge – t ells you how much gas is in your gas tank Temperature gauge or light – warns you when the coolant in your engine is too hot Oil pressure warning light or gauge – warns you when the oil is not circulating at the proper pressure Alternator warning light or gauge – tells you there is a problem with your electrical system, the alternator is not generating enough electricity to keep the engine runningBrake system warning light – tells you 1st that your parking brake is engaged and 2nd that there is a problem in your braking system Antilock braking system light – tells you that your ABS is working properly Safety belt light – reminds you to fasten your safety belt Air bag warning light – tells you that your air bags are working properly Turn signal indicators – tells you which direction that you have indicated you are going to turn. Most are small green arrows. High beam indicator – tells you that your high beam head lights ar e on, blue light. VEHICLE CONTROLS Steering wheel – controls the direction of the front wheels.Turn right to go right and turn left to go left. Steering wheel adjustment lever – can tilt the wheel up and down Selector lever – lets you put the car in a gear. Either on the steering column or in the center console. Gear shift lever – lets you put a manual transmission car into a gear. Ignition Starter switch – you start the engine by putting the key into the ignition switch. Page 42 – picture or positions Cruise control – lets you set and maintain a certain speed. Parking brake – keeps the car in place when it is parked. Locations? Clutch pedal – is in a manual transmission car, is located to the left of the foot brake and s pushed down (in) to change gears. Foot brake pedal – push the pedal down to slow and stop the car. Also makes the brake light on the back of your car light up. Accelerator pedal – Located to the right of the brake pedal, push it down to get the car to go faster, release the pedal to get the car to slow down. SAFETY, COMMUNICATION & COMFORT DEVICES Safety belts – always wear you seat belt when your car is in motion. It will help protect you from injury in a collision. Head restraints – padded devices that help prevent head injuries in collisions. Inside and outside rearview mirrors – these mirrors help you see what is behind your car ithout turning around and looking. Blind spots are the areas that your mirrors do not show you. Horn – located on the steering wheel. Hazard flasher control – located on the steering wheel or control panel. Turns on both sets of turn signals when engaged. Windshield wipers and washers – one switch for both usually, it turns on your wipers and squirts water onto your windshield to clean off the dirt. Light switch – controls the headlights, taillights, side marker lights, instrument panel, li cense plate and dome light. Hood release lever – located on the left side under the instrument panel, pull to release he hood, then go out and open by releasing the front latch. Heater, air conditioner, and defroster – heating and air conditioner warm and cool the car passenger area and the defroster keeps the windows clear of moisture. Sun visors – located above the windshield, pull down to block the sun. Seat adjustment lever – usually at eh lower front or left side of the seat. GETTING READY TO DRIVE Outside Checks 1- Walk around the car looking for obstructions and spills. 2- Glance at the tires. 3- Where are the front wheels pointed. 4- Make sure that the windows are clean and clear. Lights also. – Check back window ledge for sight obstructions. 6- Look inside for any unwanted passengers. Getting into the car 1- Have your keys ready, especially if you enter from the road side. 2- Walk around the front of your car and back to the door facing tr affic. 3- Get in quickly, lock the doors and put the key in the ignation. Inside Checks 1- Lock the doors 2- Adjust your seat and steering wheel so that you are about 10 inches from the wheel 3- Your hands should be able to reach the steering wheel with your elbows slightly bent and you should be able to reach the pedals with your knees slightly bent. – Your head restraint should be adjusted to hit the middle of your head. 5- Adjust your rear view mirror and side mirrors 6- Fasten seat belts. DRIVING AN AUTOMATIC VEHICLE Gear selector lever positions: P = park – transmission is locked in this position. R = reverse – used for backing up (backup lights) N = neutral – allows the wheels to roll without engine power D = drive – moves your car forward (overdrive) Low (L1, L2 or 1,2) = allow you to put more power to the wheels at lower speeds Starting the Engine 1- make sure that the parking brake is set 2- gear selector is in park – don’t p ress the accelerator (fuel injection) 4- Turn the key to ON and then START. Release the key when the engine starts 5- Check your gauges, lights and fuel level CHAPTER 4 Managing Risks with the IPDE Process The IPDE Process Every driver uses some kind of process to help them drive. Those who don’t, have a higher risk of collisions. The IPDE process helps reduce these risks. Risk can cause collisions. Factors that contribute to this risk are the driver, the vehicle, the roadway and the environment. Driver-contributed factors: – adjusting the radio – being angry or upset – blurred vision grooming – driving while drinking – cell phones If you are doing one or more of these and the driver you meet is doing one or more of these then you are increasing your risk. You can control what you do but you can’t be sure about what the other driver is doing. Vehicle-contributed factors: – bald tires – bad brakes – dirty windshiel d – broken or burnt out headlights – worn out wiper blades Roadway and environment-contributed factors: – bright sun – construction – dark shadows – snow or ice – sharp curvesGood drivers make an effort to lower these risks if at all possible. Taking care of your vehicle and practicing a process, such as the IPDE, you can lessen your risks while you drive. The IPDE process Safe driving depends of your ability to see and analyze traffic situations correctly. The driving task is mostly a thinking task. When you are not thinking about your task of driving you increase your risk of a collision. By using the IPDE process you can develop the habits that allow you to drive more effectively while thinking of other things. The four parts of the IPDE, identify, predict, decide and execute.The IPDE process can be enhanced with the aid of The Smith System: – Aim High – Get the big picture – Keep your eyes moving – Leav e yourself a way out – Make sure they can see you As well as the Zone Control System: – See a zone change – Check other zones – Create time and space by getting the best speed control, lane position, and communication Identify – you must know when to look, where to look, how to look and what to look for. The sooner you can learn to identify the correct things the more time you will have to react.The Zone Control System aids you in this. You have six zones around your car, each zone is about the width of a lane and extend as far as the driver can see. (pic. 65) An open zone is a space you can drive without a restriction to your line of sight or your intended path of travel. Your target area is the section of the road that is the center of your intended path. Far out there, up the road. A closed zone would be an area that your car can not go into without conflict. Book example is a red traffic light. You have to react to the light. The sooner you ide ntify the closed zones the more time you have to respond.You should develop searching habits in three ranges: 1- your target area range – as far as you can see 2- 12-15 second range – 12 to 15 sec. in front of you 3- 4-6 second range – where your car will be in 4-6 seconds How to develop an Orderly Visual Search Pattern: steps on page 67 Your Field of Vision affects how you search. Most people have a field of vision which covers about 90 degrees to each side or 180 degrees total. Central Vision is what you are focusing on, it’s about 10 degrees. Peripheral Vision is the rest of your field of vision that is not in focus.When you are scanning the scene you need to Aim High in Steering. This means to look down the road, into your target area, and not just in front of your car. You also need to keep your eyes moving, this helps you scan the scene. If you put all of these scanning methods together you will Get the Big Picture. What do you need to look for? Loo k for open zones – you want to look for things that could cause the open zone to close. Look for other users – look for anyone who could affect your path of travel. Ground viewing – look at the vehicle approaching for clues that they will come into your path.Look for roadway features and conditions – intersections, hills, curves, width of the road (multilane to single lane, change in width of lane, surface & hazards) Look for traffic controls – know where controls are located at different times and places. Predict – once you have identified, you need to predict how the hazard might affect your path of travel. How you go through the predicting process will help determine how the hazard may affect you. Learning how to look at a situation is important. You must identify all possible hazards to determine what each one may do. Knowledge of driving laws and this class will help you predict.You know what the driver is supposed to do and how they ar e supposed to react to certain traffic situations. You must however make yourself prepare ahead of time for situations that could occur. Play the head games at times. The main thing that makes you a better predictor is EXPERENCE. You can’t get it if you don’t experience it. The two things that you must be able to predict are the actions of other vehicle users and the way your car is going to react in situations. When predicting the actions of others you need to look at their path of travel, the actions they may make, do I have an open zone? , and where might the point of conflict be?Predicting the reactions of your vehicle is the easiest of this process. You should know what condition your car is in, how are the tires, how soon can I stop, etc. Decide – Once you have identified and predicted what may happen, you now need to decide what you need to do. Maintain, swerve, brake, speed up, or just communicate with my lights or horn. You may decide to change your spe ed. You can avoid conflicts by maintaining, slowing down, or speeding up. To make a change in direction you need to look at your zones. Try to leave yourself a way out or cushion so you are able to move into that area without conflict.You may also avoid conflict by changing you position in your lane. You may need to be centered, slightly left or slightly right in your lane. If you decide that all you need to do is communicate with the other driver you may do this by your lights, horn, car position or eye contact. You want to try to minimize your number of hazards by separating the hazards. Sometimes you are going to have to pick the hazard that will possibly do the least amount of damage. This is compromising space. Give way to the big truck swerving into your lane. Execute- Once you make your decision you need to execute it. Remember, DON†T second guess yourself.The three areas that you have execution control over are speed control, steering, and communication. The hardest th ing when driving is how so I handle multiple conflicts that occur? Being able to use the IPDE process effectively takes practice and time. You are not as good at using it today as you will be next week. You will learn how to use the IPDE process selectively. This means that you start one process and something else will come up that makes you begin the process all over again. Remember this: You used the IPDE Process getting to this class today and you will use it again going to every class you take today.Chapter 5 Natural Laws and Car Control In this chapter you will learn about gravity and energy of motion, friction and traction, stopping distance and controlling the force of impact. Gravity – Gravity is the force that pulls you to the earth. Going up and down hills in a car you can feel the pull of gravity. You need to be able to adjust your driving to accommodate for this pull. The point at which your car’s weight is evenly distributed is called the center of gravity . The lower the center of gravity, the better the handling of the car. Energy of Motion – Energy of motion is called kinetic energy.What you must understand about this energy is the way it will affect your driving. The faster your vehicle is moving, the more energy you have, the heavier it weighs, the more energy of motion it has. Two important facts to know† 1- Your energy of motion doubles when the weight doubles 2- Your energy of motion increases by the square when your speed increases by a certain amount. ( speed doubles – energy quadruples) If your energy of motion increases your stopping distance will also go up that amount. Friction and Traction Friction is the force that keeps your tires from sliding on the road.Traction makes it possible for your vehicle to grip the road for you to change speed and direction. The grooved surface of the tire is called the tread. This tread cuts through the water on the road allowing your tire to grip the road. As the amou nt of tread decreases, the amount of traction also decreases. If the tire tread gets worn almost completely off (bald tire) the possibility of a blowout becomes great. A blowout is when the tire loses all pressure at once. The way your tire is inflated also determines how much of the tire tread is touching the road. An under inflated tire causes the tread to gap in the middle.An over inflated tire causes the tire tread to only touch in the middle (like a balloon) Things that could reduce the traction you have are: 1- bad tires 2- bad shocks 3- faulty steering system 4- road surfaces Checking for traction while you are driving can be done but must be done carefully. – check rear zone – brake gently for response – if you don’t slow down reduce speed Driving on curves can be very tricky. The energy of motion tries to keep your car in a straight line but the traction from the tires pulls you around the curve. Driving around curves: – Speed – red uce your speed to avoid skids 2- Sharpness – the sharper the curve the more traction you will need to go around it. 3- Banked – most curves are banked, this helps prevent your car from wanting to stay in a straight line. 4- Load – The heaver the load or weight of your vehicle the more friction it is going to take to get through the curve. Stopping Distance Total Stopping Distance – the distance your car travels while you are making a stop. Total stopping distance is made up of three parts: 1- perception distance 2- reaction distance 3- braking distance Look at the chart on page 98.To estimate the distance you need to stop you can use the four second rule. – pick a spot in the road, a sign or driveway – When the car in front of you reaches that point begin counting, one-thousand one, one-thousand two†¦ – If your car gets to that same point after you reach one-thousand four you have enough space to stop if you need to. Factors that affect you’re stopping distance: – Speed – the higher the speed the longer the distance – Car condition – worn out tires, etc need more distance – Surface – rain, snow, ice, dirt, leaves & gravel increase the distance Driver ability – if distracted or impaired you increase the distance – ABS – helps when stopping while turning – Hills – up or down hills shortens or lengthens the distance – Loads – the weight of your vehicle, heavier takes longer. Force of Impact The force at which a moving object hits another object is force of impact. Force of impact is determined by: 1- Speed 2- Weight 3- Distance between impact and stopping Safety Belts When you are in a collision, three collisions actually take place. First the car hits an object and stops.Second, you hit the inside of the car or a restraining device (seat belt) Third, your body organs slam against your skeleton or each other. Ther e are two types of restraining devices: 1- restraining devices – seat belts 2- passive restraining devices – air bags (automatic) Air Bags Air bags deploy automatically. They are there to protect your life. When an air bag deploys it comes out at a speed over 200 mph. Air bags are designed to work with the seat belts. Just relying on the air bag will not save your life. To avoid the air bag injuring your arms or shoulders you need to keep your hands about 9 and 3 or a little below.You don’t want to sit too close to the air bag, @ 10 away is good. Tilt your steering wheel to deploy the bag at your chest and not your face. Of course, child seats need to be in the rear seat or facing away from the air bags. Some air bags now have a feature that senses the weight of the person in the seat and will deploy in two stages. Some vehicles have switches for you to turn the passenger air bag off. Other protective devices in vehicles today: n Automatic seat belts n Front and rear crush areas n Energy absorbing bumpers n Side door beams n Reinforced windshields Energy absorbing steering wheel and column n Padded dash n Child seats built in n Head restraints Chapter 6 Performing Basic Vehicle Maneuvers STEERING Straight forward: hands should be at a comfortable spot, look ahead and avoid looking at your feet and hands. You need to pay attention to what is approaching you. Try to avoid over or under-steering: over-steering is when you make too sharp of a turn and you weave from side to side; under-steering is when you don’t turn the wheel enough to keep it on its intended path. When you are trying to back a straight line (driving test skill) you need to: – keep the brake pressed and put the car in reverse 2- turn your body to the right, put your right arm over the back of the passenger seat and look out of the back window. 3- Place your left hand at 12 o’clock on the steering wheel 4- Release your pressure on the brake enough to get m oving 5- Adjust your position by turning the wheel in the direction that you wish to go 6- Keep you foot over the brake (covering) and take quick glances to the front and sides checking for traffic. When you wish to stop keep looking out of the back window until you have come to a complete stop. SIGNALINGMake it a habit to signal your intent every time you plan to turn or stop. You must use your turn signals when you are making a left or right turn, changing lanes, & pulling over to the side of the road. Make sure that you know the hand signals for when you are driving. Left arm out and angled up = right turn Left arm out and pointing straight out = left turn Left arm out and angled down = braking You need to remember to signal early but not too early. CHANGING LANES You must be able to make the lane change smoothly and safely each and every time. Try to get the steering down. You don’t want to over or understeer. Steps for a lane change: – Check traffic in front and t o the side in which you are going to move into 2- Signal your intent and check your blind spot 3- Increase your speed slightly as you steer into the next lane; if it is clear to do so 4- Cancel your signal, if it did not do so automatically, and adjust your speed and steering. MAKING TURNS AND TURNABOUTS Two methods for steering your car: 1- Hand over hand 2- Push – pull Left and Right Hand Turns You should make a turn only after you have checked traffic. 1- Look for pedestrians and oncoming vehicles; check your rear zone for cars getting ready to pass you. – Plan well in advance. Put yourself in the correct lane well before the turn. 3- Obey all traffic signals and controls plus roadway markings. When turning left you MUST yield to oncoming traffic. Procedures for turning: (page 114) 1- Get in the proper lane 2- Brake early and get to the proper speed 3- Do a visual search 4- Before the crosswalk you should be at about 10 mph 5- Turning right you need to check left th en right and begin your turn when your front bumper reaches the curve of the curb line. 6- For a left turn check left then right and then left again.Begin your turn when your front bumper gets to the center of the intersection. 7- As you begin your turn check your blind spot and turn into the first lane you come to. When you are backing to your left you want to look more over your left shoulder to where you are trying to back. If backing right you want to look over your right shoulder. You will use hand over hand steering and do the visual search before you begin the maneuver. Turnabouts Precautions when you are planning to do a turnabout: †¢Be sure that local laws permit it †¢Need at least 500 feet of visibility Don’t do on hills or curves or within 200 feet of an intersection †¢Should not be done where high-speed traffic or any traffic would be †¢Check all zones while doing the turnabout U-Turn Select your spot and signal right to move over and stop. Whe n the way is clear, turn on your left signal and move into the lane Check your front and left rear zones and your blind spot. Turn the wheel hard left and move through the turn until you have completely turned around. Driveway turnabouts Backing into on the right Pull in on the left Pull in on the right Which of these is the safest? Three point turnabout (driving test skill)Check your zones, signal right and pull to the curb (or side of road) and stop Signal left, turn the wheel hard left and pull across the road as far as you can Signal right, put the car in reverse, turn the wheel hard right and back as far as you need to back Signal left, put the car in Drive, turn the wheel hard right and pull forward finishing the turnabout. Parking When you are trying to park you need to have speed control, steering control and accurate judgment. Before parking you need to find a space big enough for your car to get into. Avoid end spaces or beside large trucks or poorly parked vehicles.You ne ed to learn some reference points for parking. You will be exposed to standard reference points, these are for a typical vehicle and driver, and you will learn your personal reference points, ones that you like to use. Angle parking: This parking is done diagonally to the curb. Mostly in shopping center parking lots. 1- Check for peds. Position your car about 6 feet from the parked cars. Signal right and begin braking. 2- Check your right blind spot and continue braking. 3- Move forward until you can see the middle of the space without obstructions. Turn your wheels hard right and ease into the space. – Straighten your wheels when you are in the center of the space and pull forward as far into the space as you can. Perpendicular parking: This parking is when your car is at a right angle to the curb. 1- Set up about 8 feet from the line of parked cars or as far over as you can. Signal right, check your blind spot, and begin braking. 2- Check traffic to the rear and continue br aking. 3- Turn hard right when your front bumper passes the back bumper of the car to the left of the parking space. Slowly enter the space and check your rear right to make sure that you have missed the car. – Straighten the wheels when you are centered in the space and pull forward. Leaving both of these spaces (angle and perpendicular) 1- Ease straight back with your foot covering the brake. 2- When your front bumper is even with the rear bumper of the car to your left turn hard right. 3- Back into the nearest lane and straighten your wheels. Put the car in drive and pull away. Parallel parking (driving test skill) This is parking your car parallel to the curb. Select your space that is 5 – 6 feet longer than your car. 1- While approaching the space, signal right and brake.Stop with your car 2-3 feet away from the car on the right and your back bumper even with the back bumper of the car to the right. Put the car into reverse and check traffic. Turn the wheel hard r ight and ease into the space. 2- When the back of your seat is even with the back bumper of the car to the right straighten the wheels. Ease straight back into the space. 3- When your front bumper is even with the rear bumper of the car to your right turn the wheels hard left. Ease back looking out of your rear window. 4- When your car is parallel to the curb straighten the wheels and stop.Pull forward and center your car in the space. Put the car in park. My cues when we do this in the car: Wheels – hard right, straight, hard left Reference points – back bumpers even, rear of seat even with bumper, front bumper even with the rear bumper, don’t hit the barrier. Parking on hills: Up hill with a curb – turn the wheels left, ease back to touch the curb, engage parking brake, put car in park, turn the car off. Up hill without a curb, Downhill with or without a curb – turn the wheels to the right, ease until you touch the curb (if there is a curb), enga ge the parking brake, turn the car off.Chapter 7 Negotiating Intersections Searching the Intersection When you are approaching any intersection there are things that you need to look for. The main cause of collisions in intersections is the driver's failure to identity a safe path of travel. Clue you need to look for: Signs and lights Roadway markings Crossing traffic Park car on the cross street Turning traffic Rows of fences and mailboxes Traffic stopping Power lines Most intersections are + or X, but some are Y or T When you are approaching an intersection you need to check your front zones to make sure that your path of travel in open.Look for anything that may cause your path to close and cause you to change your plans. The closer you get to the intersection the more you need to search your side zones for obstructions. Scan and focus on what may cause you a problem, don't just keep your eyes in constant motion. Once you approach your point of no return you need to continue thro ugh the intersection but still scan your zones. Your point of no return is the point at which you can no longer make a safe stop outside of the intersection. Sometimes when you get close to the intersection your path of travel closes causing you to need to change lanes.Do this at an intersection only if there is no other option. You are not allowed to legally change lanes within the intersection. If your decision at the intersection is to stop, for what ever reason, you now need to do the full 180 degree scan before you inter the intersection. Controlled Intersections A controlled intersection is one that has signs or lights that determine the right of way. With signs – The two signs that control an intersection are Stop and Yield. At a stop sign you MUST come to a complete stop and at a yield sign you need to slow down and give the right of way to any vehicle in the intersection.At stop signs you need to begin your search of the intersection well back of the stop sign. As yo u approach you need to scan front, as well as 45 degrees to the right and left for anything that may interfere with your path of travel. Crossing Traffic with a blocked view†¢ Search your front and rear zones, look for pedestrians and prepare to make your legal stop at the sign, ease up to the intersection and stop again, scan for obstructions and inter the intersection only when it is clear for you to go through the intersection without conflict. (7 sec gap) Joining traffic – right turns Go through the same checks as above. When you get stopped at the sign and can't see, ease up until you can without going into the intersection and stop again. Look for a gap of at least 7 seconds. When you have a clear path make your turn and accelerate keeping the car about 4 feet from the side of the road. Joining traffic – left turns †¢ Do your scans as with the other approaches. Stop at the sign and pull forward and stop again before entering the intersection. When the w ay is clear (7 sec gap) move forward and recheck your zones. Accelerate into the proper lane and adjust your steering.Light Controlled Intersections When you are approaching an intersection controlled by lights you need to use your IPDE process to determine what the intersection will be like when you reach it. How may the lights change your path of travel? Stale Green Light – this Is a light that has been green for a while, expect It to change Fresh Green Light – this is a light that has Just turned green, you may still not have a safe path of travel. Check your intended path for obstacles. Yellow Light – this is a light that is telling you that the intersection is closing to your traffic lane.If you have reached the â€Å"point of no return† you have to determine whether to proceed through or try to stop, hat can influence this decision? Red Light – at this light you MUST stop. You need to check your rear zones as you apply the brakes. An unprotec ted left turn is a left turn done at an intersection that does not have a left turn green arrow. You MUST be sure that you can complete the turn before beginning it Protected Left Turns At these turns you will have three things apparent 1- Left turn light, this is an entire light sequence (R,Y,G) to guide you at your left turn. – Green arrow – appears with the normal light system, when the arrow goes off you simply do not have a protected left turn. 3- Delayed green light – at these lights you light is green and the opposing traffic light is still red. Turning on Red Light Right on red means that you are allowed to make a right hand turn at a red light AFTER you have made a complete stop and have scanned the intersection. When it is safe to proceed you can make the turn. Left on red is allowed in most states when you are turning left from a one-way street onto a on-way street going to your left.Some states allow this if you are in a left turn only lane (two way traffic) and are turning onto a one way street. A controlled railroad crossing has lights and/or a stop arm. You must come to a complete stop and stay until the lights have stopped flashing and the arm has come up. DO NOT EVER go around the stop arm to cross. Uncontrolled Intersections An uncontrolled intersection is one in which there are no traffic controls. As you approach one of these intersections you MUST expect traffic problems. NEVER assume that the other driver will give you the right of way. You must really use your IPDE process as you approach these intersections.It is best to treat these intersections as yield signs. There are also uncontrolled railroad crossings. Simply slow down, scanning the tracks for trains and do not cross if you see or hear one coming. Determining Right of Way Right of way describes the privilege of having immediate use of a certain part of the roadway. Right of way is GIVEN not taken. You may have to YIELD and allows others to go first in order t o be safe. Judging Gaps A gap is the distance between two vehicles. When you are at an intersection you have to make sure that you can successfully get through the intersection. Chapter8 Sharing The RoadwayWith Motorcycles: About 2000 people a year are killed on motorcycles. The primary reason is there are so many body parts not protected when riding a motorcycle. You MUST use the IPDE process when motorcycles are around. They can hide in spots, they spend longer times in your blind spots and many cyclist take more chances that car drivers do. ‘†¢Ã¢â‚¬ ¢Ã¢â‚¬ ¢Ã¢â‚¬ ¢Ã¢â‚¬ ¢ †¢ ‘†¢Ã¢â‚¬ ¢Ã¢â‚¬ ¢Ã¢â‚¬ ¢ †¢ †¢Ã¢â‚¬ ¢- †¢Ã¢â‚¬ ¢Ã¢â‚¬ ¢ †¢ ‘ ‘ -i -†¢Ã¢â‚¬ ¢ ‘†¢ -‘- ;†¢Ã¢â‚¬ ¢; †¢;†¢ Problem areas in which you need to really look for motorcyclist: a vehicle turning left in front of a motorcycle a vehicle turning right at an intersection or into a driveway a motorcycle turning left inblindspots a tailgating motorcyclist one passing you on the right or left – meeting an oncoming motorcycle When you are going to pass a motorcycle you need to stay well back to avoid shocking the cyclist, use the entire lane to make the pass and wait until you can see them in your rearview mirror to move back over. It is just like passing a vehicle. With Bicycles, Mopeds and Motor Scooters: Bicyclist need to remember that when they are on the road they have the responsibility to follow ALL of the traffic laws just as the other vehicles do. They need to wear a helmet, know the rules for riding on roads as well as idewalks, and wear light colored clothing (especially at night), keep from wearing headphones, and keep their bike in good condition. When you encounter a bike you need to increase your scanning to avoid serious conflict. If you pass a bike you need to follow the same rules as passing a car. Remember that some bicyclist do not have great control over their bike and may swerve o r fall into your path. Mopeds and scooters create the same types of problems as bikes do. They are low powered and very small. They are hard to see and the people riding them may not be able to handle them properly.People on mopeds and scooters do not have to have a drivers license but they do have to follow the rules of the road, just as bicyclist and drivers do. Pedestrians Pedestrians are the most vulnerable users of the HTS. It is the drivers responsibility to protect the pedestrians. Children and old people are at most risk. Children do not know about consequences and old people may not hear or see well. When you drive in an area with pedestrians you need to heighten you IPDE usage. Look for pedestrians in areas where you expect to see them. Playgrounds, sidewalks, residential areas, parks, and parking lots.Sharing the roadway with emergency vehicles is a common thing in populated areas. You should yield the right of way to the emergency vehicles when they are traveling with th eir light and/or sirens on. Simply move to the right side of the road if you can and or to the lane as far to the right as possible. If you have to you can stop but make sure that you are as little a hazard as possible. With Trucks: The type of truck you need to really worry about when driving are the big semis (18 wheelers, tractor trailer, transfer). The main reason is that they are sooo big and can do a whole lot of damage to your car in a very little amount of time.These larger trucks make wide right turns. When you are near one and they put on their right turn signal you have to make sure that you are not to their right because the trailer of the truck will turn into your lane when they turn. You need to avoid following these trucks because they have big blind spots which make you hard to see. If you can not see their face in the mirror, they can not see your car. Use caution when passing a truck. Because their blind spots are larger you have to make sure that they see you duri ng your pass as well as before your pass.When you meet a large truck on a two lane roadway you need to prepare for the after wave when they go by. The air that they push to the right and left will make your car jump of vibrate. Also on wet roads the trucks will throw up water that will cover your windshield. Simply grasp the steering wheel tightly and steer through the problem. Chapter 9 Driving in Urban Traffic Adjusting to Urban Traffic Two of the main factors that make urban driving difficult: 1- Traffic is more dense – there are more cars, buses, trucks and pedestrians per mile than on rural roads – City hazards are closer to you – more things are closer to your car than in the country. Mile per mile, city roads have the highest number and variety of hazards. It takes time to do the IPDE process and in cities you don't have as much time to process the information as in the country. When you are on urban streets you have to pay attention and try to identify h azards as early as possible. Following Traffic on City Streets Space cushion refers to the space between your car and the car in front of you. If you have a good space cushion you have some advantages: 1- You can see further ahead and get the â€Å"big picture† – You can be seen better 3- You have more time to do the IPDE process 4- You are in better position to avoid the car in front of you if they stop suddenly. The 3-second following distance. When you are 3 seconds behind you have enough cushion to avoid most collisions in most normal driving situations. 1- Pick out a spot on the road ahead 2- When the car in front gets to that spot begin counting; 1001,1002,1003 3- If your car has not gotten to the spot by 1003 you have enough cushion to avoid a collision. If you reach the spot before you get to 1003, you need to back off a little.The faster you are traveling the bigger your space cushion will be. Being Followed on City Streets A tailgater is a vehicle that is fol lowing you too closely. The main hazard of a tailgater is that if you have to do a sudden stop they will hit you in the rear. They think that they are saving time by going so fast and getting close to you. If you have a tailgater behind you, you need to increase your following distance so you will not have to react as quickly when a car in front of you makes a sudden stop or move. When you are meeting cars in the city you have to really look ahead for your front zone to close.Oncoming drivers may cross the center line and block your path. Reasons that people cross the center line are: 1- driver impairment 2- poor judgment 3- poor visibility 4- reduced space 5- sudden moves for others 6- vehicle failure 7- turning car, buses or trucks 8- double parked vehicles Managing Space on Urban Streets Look ahead – try to see at least one block ahead but if you can see farther, look as far as you can but IDENTIFY possible problems. , When you are approaching a traffic light and you first see the light green you need to expect it to change.If you see a green light but the crosswalk light is flashing â€Å"don't walk† you need to anticipate that the light is getting ready to change. NEVER speed through an intersection trying to beat the light. Covering you brake means that you have taken your foot off of the accelerator pedal and have it in front of the brake pedal, but not pushing it down. You are anticipating that you are going to need to brake. This takes away your reaction distance/time if you need to brake suddenly. Riding your brake means that you have your foot on the brake pedal and you are pushing it down slightly.Most people that two foot drive end up riding their brakes. On city streets that have parked cars on your right you need to anticipate that a car door may open when you get to it. To help avoid hitting the door you need to drive about the width of a car door away from parked cars. Chapter 10 Driving in Rural Areas Characteristics of Rural Tr affic 82% of all of the roadway miles in the US are considered rural roads. When you approach a curve on a rural road with an advisory speed limit, you should be at that posted speed before you enter the curve.Advisory speeds are posted to help keep cars from having a collision on a curve because they entered the curve at too great a speed to control the car. Speed kills on rural roads. Twice as many deaths occur on rural roads as opposed to urban roads. On rural roads in normal (ideal) conditions the 3 second rule for following is sufficient. If you are following another car using the 3 second rule and a car cuts in between you and the other car you need to reestablish your 3 second rule with the new car. The basic speed rule states that you should not drive faster than the road or traffic conditions allow you to.It is more difficult to maintain control of your car at higher speeds. When you are driving on rural roads you are going to encounter slow moving vehicles, animals in the road and oncoming traffic that is close to you. Roadside hazards that you will come across are narrow shoulders, bridges, ditches, guardrails, and trees. You are not going to have as many tailgaters here because of the type of driving you are doing plus there are not as many cars on the road. In rural areas your speed is going to be faster so your IPDE process is affected. At higher speeds you decrease your time to make a decision using the process.So the faster you are driving, the farther you need to look ahead so you can perform the IPDE process. When driving on these roads you may see mailboxes, reflectors on posts, or small utility lines. These are all clues that you are approaching a driveway. When you are driving in the mountains you are going to come to sections of the road that have sharper curves and steeper hills. When you are going down a steep hill you should NEVER shift your car into neutral. If you change gears you need to shift to a lower gear to avoid burning your b rakes. Passing in rural areas is done generally on two lane/two way roads.If you are passing another car you must make sure that you can complete the pass safely and before the passing area ends. When you think that you need to pass another car you need to think before you pass. One main question that you need to ask is, is it safe to pass here? When driving at night on rural roads you are going to encounter car light that pop up from around curves or hills. To avoid being temporarily blinded you need to look to the right side of the road, white line. Chapter 11 Driving on Expressways An expressway is defined as a roadway that has limited-access or controlled-access.Driving on expressways is more dangerous because of the higher speeds and the number of cars. For this reason, collisions on expressways are generally more serious. Expressways have minimum speed limits posted. If you are going below this minimum speed then you are a hazard on the roadway. To drive effectively on express ways you must be willing to cooperate with other drivers. They also have multiple lanes which means that when you change lanes you need to do so one lane at a time. You are driving on an expressway and you need to exit; the ramp you need to get off on is totally Mocked by traffic, preventing you from getting over.Wiat should you do? Go to the next exit and come back up the expressway. If you get onto the wrong entrance ramp you should go ahead and get on the expressway and travel to the next exit, get off and turn around. It is NEVER permissible to back up an entrance ramp. The entrance lane has three parts; the ramp, the acceleration lane and the merging lane. When you are coming down the ramp you need to check for a gap to merge into by looking over your left shoulder as well as into your left mirror. If you are entering an expressway on the entrance ramp and your way is blocked so that you can not merge onto the road you should avoid stopping.Stopping on the ramp in the accelerat ion lane can cause a rear end collision. If you are driving in a group of car on an expressway you are driving in a â€Å"wolf pack†. You are driving in the center lane of the expressway and you keep getting passed on the right and left, you should move into the right lane to avoid being a hazard. Highway hypnosis happens when you get lulled into staring while driving. If you stare for long enough you will put yourself to sleep. If you are taking a long trip on expressway you need to plan ahead for food, fuel and rest This will make your trip more enjoyable and safe.
