40 Million Years of Dog Evolution

40 Million Years of Dog Evolution In many ways, the story of dog evolution follows the same plot line as the evolution of horses and elephants: a small, inoffensive, ancestral species gives rise, over the course of tens of millions of years, to the respectably sized descendants we know and love today. But there are two big differences in this case: first, dogs are carnivores, and the evolution of carnivores is a twisty, serpentine affair involving not only dogs, but prehistoric hyenas, bears, cats, and now-extinct mammals like creodonts and mesonychids. And second, of course, dog evolution took a sharp right turn about 15,000 years ago, when the first wolves were domesticated by early humans (see a gallery of prehistoric dog pictures). As far as paleontologists can tell, the very first carnivorous mammals evolved during the late Cretaceous period, about 75 million years ago (the half-pound Cimolestes, which lived high up in trees, being the most likely candidate). However, its more likely that every carnivorous animal alive today can trace its ancestry back to Miacis, a slightly bigger, weasel-like creature that lived about 55 million years ago, or 10 million years after the dinosaurs went extinct. Miacis was far from a fearsome killer, though: this tiny furball was also arboreal and feasted on insects and eggs as well as small animals. Before the Canids: Creodonts, Mesonychids, and Friends Modern dogs evolved from a line of carnivorous mammals called canids, after the characteristic shape of their teeth. Before (and alongside) the canids, though, there were such diverse families of predators as amphicyonids (the bear dogs, typified by Amphicyon, which seem to have been more closely related to bears than dogs), prehistoric hyenas (Ictitherium was the first of this group to live on the ground rather than in trees), and the marsupial dogs of South America and Australia. Although vaguely dog-like in appearance and behavior, these predators werent directly ancestral to modern canines. Even more fearsome than bear dogs and marsupial dogs were mesonychids and creodonts. The most famous mesonychids were the one-ton Andrewsarchus, the largest ground-dwelling carnivorous mammal that ever lived, and the smaller and more wolflike Mesonyx. Oddly enough, mesonychids were ancestral not to modern dogs or cats, but to prehistoric whales. The creodonts, on the other hand, left no living descendants; the most noteworthy members of this breed were Hyaenodon and the strikingly named Sarkastodon, the former of which looked (and behaved) like a wolf and the latter of which looked (and behaved) like a grizzly bear. The First Canids: Hesperocyon and the "Bone-Crushing Dogs" Paleontologists agree that the late Eocene (about 40 to 35 million years ago) Hesperocyon was directly ancestral to all later canids- and thus to the genus Canis, which branched off from a subfamily of canids about six million years ago. This western dog was only about the size of a small fox, but its inner-ear structure was characteristic of later dogs, and theres some evidence that it may have lived in communities, either high up in trees or in underground burrows. Hesperocyon is very well-represented in the fossil record; in fact, this was one of the most common mammals of prehistoric North America. Another group of early canids was the borophagines, or bone-crushing dogs, equipped with powerful jaws and teeth suitable for scavenging the carcasses of mammalian megafauna. The largest, most dangerous borophagines were the 100-pound Borophagus and the even bigger Epicyon; other genera included the earlier Tomarctus and Aelurodon, which were more reasonably sized. We cant say for sure, but theres some evidence that these bone-crushing dogs (which were also restricted to North America) hunted or scavenged in packs, like modern hyenas. The First True Dogs: Leptocyon, Eucyon, and the Dire Wolf Heres where things get a bit confusing. Shortly after the appearance of Hesperocyon 40 million years ago, Leptocyon arrived on the scene- not a brother, but more like a second cousin once removed. Leptocyon was the first true canine (that is, it belonged to the caninae subfamily of the canidae family), but a small and unobtrusive one, not much bigger than Hesperocyon itself. The immediate descendant of Leptocyon, Eucyon, had the good fortune to live at a time when both Eurasia and South America were accessible from North America- the first via the Bering land bridge, and the second thanks to the uncovering of central America. In North America, about six million years ago, populations of Eucyon evolved into the first members of the modern dog genus Canis, which spread to these other continents. But the tale doesnt end there. Although canines (including the first coyotes) continued to live in North America during the Pliocene epoch, the first plus-sized wolves evolved elsewhere, and re-invaded North America shortly before the ensuing Pleistocene (via that same Bering land bridge). The most famous of these canines was the Dire Wolf, Canis diris, which evolved from an old world wolf that colonized both North and South America (by the way, the Dire Wolf competed directly for prey with Smilodon, the saber-toothed tiger.) The end of the Pleistocene epoch witnessed the rise of human civilization around the world. As far as we can tell, the first domestication of the Gray Wolf occurred somewhere in Europe or Asia anywhere from 30,000 to 15,000 years ago. After 40 million years of evolution, the modern dog had finally made its debut!

ESL Dialogue to Make an Appointment With the Dentist

ESL Dialogue to Make an Appointment With the Dentist In teaching English and a Second Language (ESL) or English as an Alternative Language (EAL)  students how to properly communicate in English, oftentimes specific examples will help them to understand the dynamics of English grammar and usage at play in real life circumstances, though it is important to also emphasize the technical rules associated with each grammatical situation. One such example of a situation an ESL or an EAL  student may encounter outside of school is scheduling an appointment at the dentist- or doctor, but its best to keep these types of exercises simple and one-dimensional to present the clearest message to students. In this scenario, the teacher should begin by playing the role of the dentist office assistant, mining answering a phone that the student, the patient, should voice.   ESL Dialogue for Practicing Scheduling Medical Appoints Dentist Office Assistant: Good morning, Beautiful Smile Dentistry, this is Jamie. How may I help you today? Patient: Good morning, Id like to schedule a check-up. D:  Id be happy to do that for you. Have you been to Beautiful Smile before? P: Yes, I have. My last check-up was six months ago. D: Great. Can I get your name, please? P:  Yes, of course, sorry. My name is [students name]. D: Thank you, [students name]. Which dentist did you see on your last check-up. P:  Im not sure, really. D: Thats OK. Let me check your chart... Oh, Dr. Lee. P: Yes, thats right. D: OK... Dr. Lee has time next Friday in the morning. P: Hmmm... thats not good. Ive got work. How about the week after that? D: Yes, Dr. Lee has sometimes open. Would you like to suggest a time? P: Does he have anything open in the afternoon? D: Yes, we could fit you in on Thursday, January 14th at 2.30 in the afternoon. P: Great. Thatll work. D: OK, thank you for calling Mr. Appleman, well see you next week. P:  Thank you, bye-bye. Key Phrases for Making Appointments to Emphasize The key takeaways from this exercise are the phrases that one might encounter at a doctor or dentists office that may be confusing to new English learners like which dentist did you see? or we can fit you in, which makes no sense in the literal interpretation of the phrase. The most important phrase for an ESL student to learn here, though, is Id like to schedule or make an appointment, but its also important to be able to understand the response, like if the office assistant had said I wish I could help as a rejection- an ESL student may not understand this means there is nothing that assistant can do to match that persons schedule. The phrase check-up and have you been to Dr. Xs before are both unique to ESL students because they present a colloquialism commonly used to describe situations specific to visiting a doctor or dentist.

Marriage in A Doll's House by Ibsen Essay Example | Topics and Well Written Essays - 1250 words

Marriage in A Doll's House by Ibsen - Essay Example Through this dilemma, and Nora’s husband’s actions, Ibsen shows a very different view about the roles of individuals in a marriage. He does this by exploring the concepts of love, trust, respect, and equal rights in Nora’s marriage. In marriages nowadays, almost all western countries accept that the husband and wife should equally respect. However, after reading A Doll’s House, I came to know that perhaps this must not have been the case in earlier times. From Act one itself, it is obvious that Nora’s husband, Torvald Helmer, does not treat his wife as an intellectual being. He speaks to her in the second-person and through name-calling, rarely referring to her directly. For instance, when Nora comes home, Helmer calls out â€Å"Is that my little lark twittering out there?† When Nora replies, Helmer once again refers to her in the same circuitous way, by asking if his â€Å"little squirrel (was) bustling about†. It is impossible not to notice this aspect in almost all of Nora’s and Helmer’s conversations. He speaks to her as if she is a pet, an animal with which one speaks one-sidedly without any expectations of intelligent conversation. According to me, this shows that Helmer does not see Nora fit enough to refer to her directly, and thus shows that he does not respect her that much. Another aspect in Helmer’s and Nora’s conversations that show his lack of respect for her is the way he treats her as a child. Although many would state that Helmer speaks to his wife kindly, I believe that he does so in a very patronizing manner. This can be seen by the way he is always lecturing her on her habit of spending too much money. Helmer even goes as far as trying to control Nora’s diet, when he asks her, â€Å"Hasn’t Miss Sweet Tooth been breaking rules in town today?†. Some might find that these two are a very sweet couple who talk so lovingly, but it is hard to ignore tr aces of contempt which appear in Helmer’s tone and actions. For instance, when Nora asks him to come and check out all the goodies she has bought, he at once calls out from his study â€Å"Don’t disturb me†. Such a change in his tone also shows the fatherly way he acts with Nora. A marriage is mainly based on love and trust, as well as respecting the other half. However, Ibsen has showed that there is no trust factor in the marriage of this play’s protagonist. This can be seen by the way Nora is so adamant is hiding the macaroons that she has bought for herself. I personally found it very strange that a wife should want her husband not to find out that she has bought a small packet of sweets (especially when he appears to be in a good mood and is insisting), even though she informs him of all her other purchases. This speaks volumes about Nora’s marriage, and it is here that Ibsen first introduces the ‘no-trust’ factor. In addition to this, Nora also hides another fact-which is far more significant than a packet of macaroons-from her husband. This fact is her borrowing of money to help her husband when he was sick, without letting him know about it. Money is another factor that plays a major role in the aspect of marriage shown in A Doll’s House. Ibsen confirms how it comes between the two individuals in a marriage by showing how it was one of the main causes behind the dissolution of Nora’

Gender, Folklore, Inequality Essay Example | Topics and Well Written Essays - 1250 words

Gender, Folklore, Inequality - Essay Example As stated earlier modern society has diversified in the categorization of human sexual orientations. The matter has affected gravely the state of law, politics and even religion. Initially, the only recognized group to emerge was homosexuals. These are the gay and the lesbians. However, some groups chose to sort of break away from the mainstream stereotype by including a more inclusive abbreviation like L.G.B.T.Q.I.A. this category includes the homosexuals for lesbian and gay, the bisexual, the transgender, the queer, the intersex and the asexual. The term transgender in definition means a person who does not identify with the normal sexual orientations of male or female. In the USA, many cases exist of people who were born male identifying themselves as females and the same applies to females. The matter has bred such controversy and discussions to the extent of affecting the law. One such example was in a case in Colorado. The child Coy Mathis was born a boy but wore pink dresses and wished people to refer to her as a girl. While in kindergarten the school’s administration prohibited her from using the girl’s bathroom and instead to use a gender-neutral bathroom. The parents pulled her out of the school soon after. This case has been at the heart of a legal issue. Colorado’s anti-discrimination laws protect transgender people and this is why this case received much public attention. Southern Comfort was a compelling story that focused on the discrimination people of different sexual orientations from the norm suffer.

Wuthering heights Essay Example for Free

Wuthering heights Essay Should Wuthering Heights be considered relevant in todays society? I say, yes. Although I must admit, I was very close to hating this book, not only because of the confusing situations which occurs and my dislike towards all characters, but also for much more reasons that I dont wish to point out at this moment for that we shall be here for a terribly long time if I did. However, I must also admit, the context of this book, Wuthering Heights, have portrayed many relevant themes that are still existing today, even as I speak. Catherines decision of marriage is one example. My love for Heathcliff resembles the eternal rocks beneath: a source of little visible delight, but necessary Nelly, I am Heathcliff. In this quote, Catherine was well aware of her love for Heathcliff claiming that they both have the same souls. She had no income or property of her own. Her physical comfort depends on the will of her father and brother and the most crucial decision of her life, to marry Edgar Linton, is determined by the fact that if she were to marry Heathcliff, they would become beggars. In my opinion, this is a case of forbidden love. Catherine and Heathcliff cannot be together as their statuses are simply too far apart. Many has pointed out that this is irrelevant today as currently, we have the freedom to marry whoever we like. Statuses and class arent considered as important anymore. But is this so? That nowadays we could say I do to whoever we desire? In the book Forbidden Love, by Norma Khouri, told on the accounts of a true story in the small town of Jordan, there is a much similar situation. Dalia, a Muslim, was in love with a Catholic man called Michael. In Jordan, it is considered extremely immoral for two people with such different beliefs to be together. As a result, Dalia was honorably killed when her secret relationship was discovered. Here, this is much like the account of Wuthering Heights. Although it is fair to argue that both stories are different; one deals with religion and honor killings when the other with statuses. However the concepts of the two are very much alike as both revolve around the idea of forbidden love. Love that can never be equated. Perhaps the procedure of murder or revenge would not appear in every situation such as this, but most definitely it will end painfully tragic. The heartbreaking story of Dalia  and Michael was real. It only happened several years ago. As I have heard in your speeches, many have pointed out that the scene of Catherines ghost was much irrelevant as opposed to todays society for that we now do not believe in the supernatural. I find this argument rather hypocritical. If I remember correctly, only a few years back, was there not a reality TV show starring John Edwards which was such a big hit, it attracted millions of viewers around the whole globe? Mr. Edwards claimed, through his television show, that he could communicate with the souls of the dead. This not only brought the attention of numerous but also their belief in him. Many say that his so-called communications is probably just a sham and arent genuine. Whether he really beholds such powers or he was simply making up his sixth sense, I do not care for that he is a person that I neither like nor like to know more of. I am merely mentioning this troublesome man to prove my point. Not of the existence of the supernatural or that ghosts do really appear through your window, but of our beliefs in it even today. As modern day citizens, our acceptance of the paranormal is still very strong. If it wasnt so, then wouldnt the ratings for a reality show of communications with dead spirits be extremely low and unpopular much like the opposite of the results of Mr. Edwards multi-million making one? Here, in the story of Wuthering Heights, the use of a ghostly scene was to attract the readers attention making the book sound interesting and engaging. Bronte addresses the bond between Catherine and Heathcliff in a spiritual way. Thus, making their love towards each other almost inseparable. As children, they had a bond that grew out of similar needs. They grew up protecting and trying to shelter each other from the abuse of Hindley and Joseph. Consequently, they developed an eternal friendship, love and affinity. One could say that they were soul mates even children. Bronte expands the notion of eternal love by creating the supernatural aspect in the story. This is illustrated when Heathcliff contacts Catherines spirit after she dies. Their souls are eternally joined so as a result, Heathcliff cannot live in this realm without her. Only their souls joined together make one. Heathcliff eventually dies to reunite his soul with Catherine. Another aspect which is relevant today and forever it shall remain relevant  is selfishness. Catherines selfish character was depicted when she wanted both Edgar and Heathcliff at the same time. In the beginning, she was introduced as a high spirited character who was wild. However, she drastically changes throughout the book. When she hurts her leg and is forced to stay at Thrushcross Grange, she returns to Wuthering Heights as a well dressed and dignified lady. She was easily swayed to the superior lifestyle of the Lintons and began to look down upon Heathcliff. She even laughs at his rough and dirty appearance and says I didnt mean to laugh at you. I could not hinder myself Heathcliff. Shake hands at least! What are you sulky for? It was only that you looked odd. If you wash you face and brush your hair, it would be alright. But you are so dirty! I as a reader was left surprised and cheated with this reversal. However, she becomes more and more selfish by the minute and even tries to change Heathcliff and begins to feel that he is in fact, beneath her. This is one of the reasons why she starts to look at Edgar in a new light. He, unlike her family, was refined, gentle, rich and handsome. When he asked her to marry him, she accepted, knowing very well that she loved Heathcliff. Ive no more business to marry Edgar than I have to be in heaven. If the wicked man in there had not brought Heathcliff so low, I shouldnt have thought of it. It would degrade me to marry Heathcliff now, so he shall never know how I love him; and that not only because he is handsome, Nelly, but because he is more myself than I am. Whatever our souls are made of, his and mine are the same, and Lintons is as different as a moonbeam from lightening or frost from fire. We could her marriage to Edgar was for all the wrong reasons. Catherine even confides to Nelly, he shall be rich and I shall be the greatest woman of the neighborhood and I shall be proud of having such a husband. It is evident that Catherine throws away love for her own selfish wants and materialistic motives. She wanted Edgar for his life and riches and Heathcliff for his soul. She didnt want to choose between the two and she never really did. She toyed with both of them by marring Edgar while still loving Heathcliff. Thus, she caused pain for the two men, by causing Edgar to be jealous and Heathcliff desiring revenge. Catherines passion towards Heathcliff ruined many lives. Later in the story, she suffers from the results of the selfish and naive decisions she makes. I wasnt sorry for her not only because I find her very much annoying, but because I felt that  she deserved it they were the bad choices that she must live with. Her character was childish and spoilt who loved to be in the centre of attention. It is not surprising why she wanted to be the most powerful woman in the neighborhood. The character Catherine, not only gives us something to hate and despise, but to also learn from. Throughout the whole story she was indeed very selfish and very rarely has she ever used her head to decide. Thus, this lead to the suffering of not only her, but many additional innocent lives in both Wuthering Heights and Thrushcross Grange. My point here is selfishness is something that only destroys happiness of not simply you, but others as well. This theme is not only relevant, but should be considered everyday. In conclusion, I still think that Wuthering Heights is a relevant text and should be studied by teenagers through high school. Even though I shall be feeling somewhat sorry for them, the book portrays the some of the most significant qualities of mankind. That is something that I cannot argue against.

Mechanical Energy :: essays research papers fc

Have you ever wondered how a jet aircraft lifts its tremendous weight off the ground, or what gives a runner the stamina to reach the finish line in a race? In order to answer all these questions we must talk about the transformation of one sort of energy into another. The jet aircraft gets its power from jet turbines. These powerful jet engines create a high-pressure stream of very hot gases that push the aircraft forward as they leave the engine. This is an example of heat being transformed into movement. This is sometimes described as Mechanical Energy. However, this transformation could not take place without the fuel that the aircraft gets within its wings or fuselage. Fuel is considered a chemical energy. This diagram shows how the jet engine acts as energy to lift the aircraft off the surface of earth. Fuel can take the form of gases, solids or liquids. When fuels combine with oxygen from the air, they release their stored energy as heat. We recognize this process as burning. The individual relies on food for fuel which contains energy-giving substances that our bodies can store until we need this energy to use our muscles. When we do use our muscles within us, we may not always be sure that heat is given off. Our bodies do not burst into flames but the perspiration on our skin is a clue to what is happening. The movement of the windsurfer has a different explanation. The windsurfer is propelled along by a sail which collects mechanical energy from the winds that sweep along the water. This energy has been produced by the sun which warms the earth's surface and sets the air above in motion. The sun's heat comes to the earth as a form of radiant energy. When the heat reaches the surface of the earth, it causes the land or seas to rise in temperature. The sun is very hot. Infact, the center of the sun can reach temperatures of up to 27 million degrees Fahrenheit. This is because of another kind of energy reaction where new substances are continually being created as others are being destroyed. This reaction is known to us as the Nuclear Reaction. Today we are trying to imitate this reaction in improving our energy supply. Scientists have calculated that the sun has enough fuel to go on producing energy at its present rate for about five billion years. On earth

Business Entity Paper Essay

There are different forms of businesses and they al have their own purpose. Some are for individuals and others are for partners but they both have different forms. Depending on the size and type of business the owners decide how they are going to start it. Also the liability behind them and the type of ownership also depends on how they decide to go. A corporation is a juridical entity established under the corporation code and register with the Securities and Exchange Commission. It has to have a minimum of five persons and up to fifteen. The liability is limited for the shareholders and are only countable for the amount of capital invested. It is more difficult to create, manage and organize. Depending on how many shares an individual has that’s how the participation of them is assign. If an individual has not that many shares they will be left out with out any participation or word in the company actions and next moves. An example would be Apple and Microsoft. Individuals ask, â€Å"What are the benefits to commerce of having shareholders and other entities that shield their members, protected from personal liability?† There are many benefits to having shareholders, one of the main reasons why individuals decide to incorporate is the personal liability protection it has on its members. The law protects the shareholder’s personal property and the shareholder is only responsible for the value of the equity they have in the company. It also has tax advantages, some incorporated business are able to lower their tax rate by reducing the salaries paid to their owners. The CEOs of these companies are able to carry out their management skills with the support of the shareholders. The ability to transfer ownership is a great benefit because in case of a death or simply selling their shares can be done without having to finish the organization and starting a new one with new owners. Another question frequently asked is â€Å"Would commerce be better served if personal liability would attach to those individuals for the misdeeds of their entity?† There are individuals that would say yes, have their personal belongings attached to the corporation. The logic behind an insurance  company is to protect individuals from mistakes, either caused by others or individual mistakes. Having a corporation gives the opportunity to a group of individuals to carry out a business idea and to have the ability to prosper or to fail without loosing all their life savings and personal belongings. Individuals make mistakes and it is not fair to loose everything on the first try.

Organisational Behaviour Report Essay Example

Organisational Behaviour Report Essay Example Organisational Behaviour Report Essay Organisational Behaviour Report Essay Conflict is non confined at the single degree entirely but is attesting itself more and more in organisations. Employees have become more blatant in their demands for a better trade. Assorted sections in an organisation face a state of affairs full of struggles due to a figure of grounds like end diverseness. scarceness of resources or undertaking mutuality etc. Conflict Dysfunctional Conflict can take an interpersonal signifier. Conflict between persons takes topographic point owing to several factors. but most common are personal disfavors or personality differences. When there are merely differences of sentiment between persons about task-related affairs. it can be construed as proficient struggle instead than interpersonal struggle. Technical and interpersonal struggles may act upon each other due to role-related force per unit areas. One may set the incrimination for low gross revenues volume on the production director non run intoing his production agenda and may get down disliking the production director as an unqualified individual. It is frequently really hard to set up whether a struggle between two parties is due to manifest rational factors. or it emanates from concealed personal factors. Conflict Functional These types of intragroup struggles arise often due to an individual’s inability to conform to the group norms. Most groups have an thought of a fair day’s work and may supercharge an person if he exceeds or falls short of the group’s productiveness norms. If the single resents any such force per unit area or penalty. he could come into struggle with other group members. Normally. it is really hard for an person to stay a group-member and at the same clip. well deviate from the group norm. So. in most instances. either he conforms to the group norm or is rejected by the group. Of class. before taking any such utmost measure. he or the other group members try to act upon each other through several mechanisms taking to different episodes of struggle. Analysis A batch of struggle is generated within organisations because assorted groups within the organisation clasp conflicting’ values and perceive state of affairss in a narrow. individualistic mode. An illustration that comes readily to mind is that of the managment-labour struggle. Labor feels that direction is working it because in malice of doing a net income. direction does nil for the economic public assistance of labour. On the other manus. direction feels that the net incomes should travel to hard currency militias so as to do the company an attractive proposition for investors. Another illustration is the struggle between technology and fabrication. Engineering lays emphasis on technological edification and preciseness and is accused by fabricating of planing merchandises that will last for many old ages but that the clients can non afford. It is maintained that since an organisation is composed of single and they had different perceptual experiences of ends and dithering values. struggle is bound to originate in the organisation. Directors of assorted sections have separate precedences and conflicting thoughts about resource allotment. Hence struggle is the ineluctable result. Subordinates may collide with the director over whether the work can be accomplished in the given period of clip or non. They might even reason with subsidiaries at their ain degree over the best possible manner to make a given occupation. Thus struggle is an ineluctable result but at the same clip it is assumed that struggle need non ever be damaging. Under some fortunes it could concentrate on jobs and incite a hunt for better and more advanced solutions to jobs. Though struggle can take to more creativeness in job resolution and be good to organisation under certain conditions. yet it is perceived that struggle as harmful- something to be resolved once it originate. The positions about human nature are that people are basically good ; trust. cooperation and goodness are given in human nature. Consequently. the major ancestor conditions which induce aggressiveness and struggle in people are the defective policies and construction ensuing in deformation and dislocation in communicating. Therefore the manager’s function in deciding struggle is to reconstruct apprehension. trust and openness between parties. It is non easy to construct a strong corporate civilization in any organisation. A strong civilization is based on strong moralss. This is really of import for the success of the organisation in the long-run. It is really easy to follow short-cut methods to make the top but the ruin besides comes at the same rate. Ethical motives guarantee that the organisation does non follow short-cut methods to accomplish success ; alternatively it stresses on the construct of sustained success. Every organisation has its ain codification of moralss and criterions in a written signifier. The codification of moralss usually contains the undermentioned points: Honesty Fairness in patterns of the company- Disclosing the inside information ; Acquiring and utilizing outside information- Disclosure of outside activities by the employer to the employee ; Each organisation has its ain set of codification of moralss. Making dialogues has been identified as one of the primary duties of any director. Negotiations may affect apportioning resources. puting capital or presenting new merchandises. If resources like work forces. money. machines. stuffs. clip and infinite were abundant. clearly any planning would be unneeded. But. typically. resources are scarce and so there is a demand for be aftering. Negotiation devising is at the nucleus of all planned activities. We can ill afford to blow scarce resources by doing excessively many incorrect dialogues or by staying indecisive for excessively long a clip. Negotiation doing under hazard: A dialogue is made under conditions of hazard when a individual action may ensue in more than one possible result. but the comparative chance of each result is known. Negotiations under conditions of hazard are possibly the most common. In such state of affairss. options are recognized. but their resulting effects are probabilistic and dubious. While the options are clear. the effect is probabilistic and dubious. Therefore. a status of hazard may be said to be. In pattern. directors assess the likeliness of assorted results happening based on past experience. research. and other information. A quality control inspector. for illustration. might find the chance of figure of rejects’ per production tally. Similarly. a safety applied scientist might find the chance of figure of accidents happening. or a forces director might find the chance of a certain turnover or absenteeism rate. Negotiation doing under uncertainness: A dialogue is made under conditions of uncertainness when a individual action may ensue in more than one possible result but the comparative chance of each result is unknown. Negotiations under conditions of uncertainness are unimpeachably the most hard. In such state of affairss a director has no cognition whatsoever on which to gauge the likely happening of assorted options. Negotiations under uncertainness by and large occur in instances where no historical informations are available from which to deduce chances or in cases which are so fresh and complex that it is impossible to do comparative judgements. Negotiations under complete uncertainness are as hard to mention as illustration of determinations under absolute certainty. Given even limited experience and the ability to generalise from past state of affairss. most directors should be able to do at least some estimation of the chance of happening of assorted result. However. there are doubtless times when directors feel they are covering with complete uncertainness. The figure of factors to be considered and the big figure of unmanageable variables vital to the success of such a venture can be mind-boggling On a personal degree. the choice of a occupation from among options is a calling determination that incorporates a great trade of uncertainness. The figure of factors to be weighed and evaluated. frequently without comparable criterions. can be overpowering.

This is a memorable demonstration that creates a spectacular reaction for students. Still, it can be performed safely. What to Expect A small piece of sodium metal will be placed in a bowl of water. If a phenolphthalein indicator has been added to the water, the sodium will leave a pink trail behind it as the metal sputters and reacts. The reaction is: 2 Na 2 H2O → 2 Na 2 OH- H2(g) The reaction is especially vigorous when warm water is used. The reaction may spray out molten sodium metal and the hydrogen gas may ignite, so use proper safety precautions when conducting this demonstration. Safety Precautions Never use a piece of sodium larger than a pea or pencil eraser.Wear safety goggles.Perform the experiment behind a clear safety barrier or at a distance from the students. Materials Sodium metal stored under mineral oilA 250 mL beaker, filled halfway with waterPhenolphthalein (optional) Procedure Add a few drops of phenolphthalein indicator to the water in the beaker. (Optional)You may wish to place the beaker on an overhead projector or video screen, which will give you a way to show the reaction to students from a distance.While wearing gloves, use a dry spatula to remove a very small chunk (0.1 cm3) of sodium metal from the piece stored in the oil. Return the unused sodium to the oil and seal the container. You can use tongs or tweezers to dry the small piece of metal on a paper towel. You may wish to allow the students to examine the cut surface of the sodium. Instruct the students that they can look at the sample but must not touch the sodium metal.Drop the piece of sodium into the water. Immediately stand back. As water dissociates into H and OH-, hydrogen gas will be evolved. The increasing concentration of OH- ions in the solution will raise its pH and cause the liquid to turn pink.After the sodium has reacted completely, you can flush it with water and rinse it down the drain. Continue to wear eye protection when disposing of the reaction, just in case a bit of unreacted sodium remained. Tips and Warnings Sometimes this reaction is performed using a small piece of potassium metal instead of sodium. Potassium is even more reactive than sodium, so if you make the substitution, use a very small piece of potassium metal and expect a potentially explosive reaction between the potassium and water. Use extreme caution.

The transformation in fashion trends is evident in perfumes, cosmetics, corsetry among others. During this old period, each fashion era concentrated on hats, hair, cloaks and capes. All these items were hand-made for individuals because sewing machines were non-existent. Rapid change in existing fashionable items results in the creation of fashion trends. These are referred to as trends because they never last for lengthy periods (Beckingham 76). Modern fashion is divisible into categories that include haute couture and ready-to-wear. Currently, there are detailed events that are dedicated to fashion. Some of these events include fashion weeks when diverse designers display their items. Significant designers in the fashion industries are present in cities such as Milan, New York Paris and London. They create fashionable items that serve diverse purposes in their targeted markets. Some famous designers include Coco Chanel, Christian Dior and Louis Vuitton (Hurlock 54). Fashion is significant in everyone’s life because of the power it gives people. For example, it allows people to experience healing therapies from the respective fashionable items they adorn. Counselors suggest that their patients must adorn beautiful clothes that would make them address their problems. Fashion also allows a country’s citizenry to pass strong messages to relevant leadership. For example, people in country’s that are at war could adorn in white attire and communicate their wish for a peaceful state. People use fashion to express their diverse personalities and attain their desired reactions from other people (Hurlock 90). Some people abuse fashion by indecent dressing which they blame on fashion. Others register this abuse by overindulgence in respective fashion items. They need to understand that appealing fashion is not

Re -submission coursework - Essay Example The courts are always bound by this principle; however, there is a possibility and exemptions when the courts can lift the corporation veil in order to reveal the true identity and character of the company under consideration. The main reason of this approach is that the law will seek to prevent a corporate organization from being misused or even abused (Prentice and Reisberg, 2011). In circumstances when the court is aware that the corporation is abusing its form, then the courts would rip off the corporate veil, and disregard the principles established by the House of Lords in Salomon vs. Salomon. On this basis, the assertions by Lord Denning in the case Little Woods Mail order, against Inland Revenue Commissioner is correct, and the courts have applied the principles established in this case, while lifting the corporate veil of companies whose cases are before the court. This paper critically looks at the concept of incorporation of the company, and its effects. It further on analyzes this concept of separate legal personality, and the principles contained in Salomon vs. Salomon (Prentice and Reisberg, 2011). This paper also relies on the 1985 companies act in supporting some of the facts identified in it. This paper also defines the concept of lifting the corporate veil, and instances when the courts can lift the corporate veil. This paper also has an analysis and evaluation section. This section is an analysis of the various concepts introduced into the paper. In meeting these objectives, this paper will use relevant case laws and authority. The conclusion of this paper is a summary of the various points addressed in it. The concept of incorporation of a company refers to the formation of new companies, that is given a legal benefit, and it is recognized as a personality under the law. The corporation under consideration can either be a business organization, a governmental institution, a sports club, a non-profit making organization, etc. A
