Origins of the Moon essays

Origins of the Moon essays The moon has fascinated mankind for many thousands of years. It has assumed a role in legend and lore alike, being worshiped as a god, and feared as a demon. Indeed, from the days when man first looked skyward, he knew the moon served some important purpose, one he could not yet comprehend. During the scientific advances of the 1600s, and the industrial and literary revolutions that soon followed, the moon played a central role in story and equation alike. Newspapers of the 1800's proclaimed the greatest "feat of physics ever accomplished": weighing the moon. And when man finally reached the moon in 1969, he accomplished the impossible dream of eons past. Nevertheless, with the boundary of space conquered, we have gained only slightly greater understanding of the giant looming in the sky. Now, scientists are attempting to answer a question as difficult as space is vast: how did the moon form? Some important factors need to be considered in order to form a successful theory about the origin of the moon One factor is the size of the Moon relative to the Earth. The Moon is about one-fourth the size of the Earth (Editors 22).. Also, the Moon's density needs to be taken into consideration. The Moon is only 60% of the Earth's density, which indicates that the Moon is lacking in heavy metals such as iron and nickel. Also the Moon's bulk composition appears to be similar but not identical to the Earth's upper mantle, which is comprised dominantly of iron- and magnesium-rich silicates (Spudis 137). A third factor that needs to be considered is the angular momentum of the Earth-Moon system. Angular momentum needs to be conserved. Therefore if the Earth slows down in its rotation then the Moon must move away from Earth a fraction to conserved momentum (Editors 23). There have been many theories over the years on how the moon became to be. Only four scientific theories have been accepted for any length of time. They are th...

Give an example from the real world where potential energy is transferred to kinetic energy. Kinetic Energy (KE) is the energy associated to the body or object in motion whereas Potential Energy (PE) is the energy stored in a stationary particle or system based on its position, specifically height. One concrete example of conversion from potential to kinetic energy is an automobile at rest on top of a hill is driven down the slope so that it is set in motion which may vary over time when the driver decides to increase or decrease its speed. 2. How would you describe the differences between heat, temperature, and thermal energy? Give examples of how each term is used. Temperature is an intensive property and a measure of hotness or coldness of an object or body of particles. On the other hand, heat is referred to as an energy transfer that takes place due to temperature difference while thermal energy is r egarded as an internal energy of a thermodynamic system. Heat flows from a region of higher temperature to a region of lower temperature and without a change in temperature, no heat is shifted. As an energy established within the system, moreover, thermal energy may either increase or decrease when work is done by or on the system and similarly, when heat is absorbed by the system or released on the

The various theoretical approaches to Employment Relations all fail to Essay

The various theoretical approaches to Employment Relations all fail to provide an adequate explanatory framework for the development and practise found within this function of management. Discuss - Essay Example (Dodge, 1997) These companies do not discover these characteristics on a resume, so they employ behavior-based interviews as well ad in depth interviews of their pertinent candidates. Southwest gathers a group of job candidates in a room and observes how they interact. They ask them questions that will reveal personality traits. (Woog, 1998) Consistent feedback is a key element in keeping employees stuck to their respective jobs. This feedback should go both ways and recommends that managers ask employees open-ended questions to provide an opportunity to express their opinions. Employees today will change jobs many times during their careers. These workers are continuous learners and they keep pace with change, take responsibility for their own careers and are committed to the company’s success. (Nink, 2006) Talent management is a function of HR that needs identification of true talent and retaining of employees who work within their instinctive levels, let alone show prowess which is best suited for meeting the desired needs of the HR function. The role of the government in such an exercise is all the more significant since it has to realize that its role is significant right from the onset. The relationship between the organization and the government is one of a symbiotic one since the organization has to recog nize the talent pool which is available and the government needs to make viable conditions for them to exist and work in the best manner possible. (Bell, 2001) The role of HR thus is to liaison these activities in the best interests of the organization as well as the linkage that it has with the government. This helps the overall mission and vision basis of the organization and helps develop the objectives on a long term basis more than anything else. The need is to realize that talent management can truly play a pivotal role

Toyota’s Accelerator and Public Relations Crisis Essay Example for Free

Toyota’s Accelerator and Public Relations Crisis Essay One of the world’s top automakers, Toyota was once one of the leaders in automobile and business improvement and manufacturing. However, in 2009 the top builder of reliable and high quality cars went through one of the largest recalls in the history of the United States. Consumers had considered Toyota one of the top in the race for automobile and automobile selling among car manufacturers. They have always had a reputation as being a leader of quality and efficiency in terms of their production and manufacturing standards. Since the recall Toyota has taken a tremendous blow to its reputation and its loyal customer basis. Consumers are questioning whether Toyota was hiding the truth from the public regarding their well know accelerator issues and why they were trying to fix the problems after the issue became serious and not immediately. Some may question if this incident will permanently affect Toyota’s reputation or if Toyota handled this situation properly. In this paper we will discuss these questions as well as the cause of the problem. Several different Toyota and Lexus models were reported to have gotten in accidents regarding acceleration issues. The accelerator’s in some of the Toyota models were getting stuck, which did not allow the drivers of these vehicles to slow down or stop in time to prevent an accident. When this issue was originally brought to light Toyota claimed that â€Å"faulty floor mat placement† was to blame and that the gas pedal would get stuck behind the floor mats which would cause the inability to slow down or stop. According to Bob Carter, general manager of the Toyota-brand division of Toyota Motor Sales USA â€Å" The risk of the accelerator getting jammed is strictly a problem of unintended loose or ill fitting floor mats ( Niedermeyer)†. â€Å"Toyota refuted speculation in the press that other defects might be causing its vehicles to accelerate uncontrollable, citing its own and federal safety studies (Niedermeyer)†. After further investigation by the National Highway Traffic Safety Administration the actual problem may not have anything to do with â€Å"faulty floor mat placement† but with several model’s accelerator  mechanism. They found that â€Å"the design of the accelerator pedal (â€Å"one-piece, nonarticulating†) allowed it to become easily entrapped in the groove of the rubber all-weather floor mat if the rubber mat was not properly secured with at least of the two retaining hooks (Jensen)†. Toyota finally issued a consumer safety advisory to all Toyota and Lexus owners at the end of September 2009 and at the end of October 2009 mailed certain Toyota owners safety notices to alert them of the potential problems. It is still unknown the exact date that Toyota knew their models were faulty but it is known that reports of the faulty vehicles began arising as early as 1999. The initial problem was not made public until problems persisted over the next 10 years. Even then it took the death of 4 individuals in California driving a Lexus with a stuck accelerator to final discuss Toyota’s accelerator issues. Toyota then announced they would be recalling millions of models of Toyota Vehicles. There were several Toyota models effected which include the company’s three best sellers- the Camry, Corolla, and Rav4 SUV. â€Å"Between them, they accounted for more than half of the Toyota brand’s U.S. sales in 2009 (Isidore)†. Although Toyota should have taken this situation more seriously years ago when the problem first happened, are they really to blame? When the accelerator problem happened to only a few vehicles throughout the years it’s hard to say that Toyota is to blame. I think the fact of the matter is that they tried to pass the buck blaming the floor mat placement instead of really investigating the issue. Had they investigated the issue more carefully consumer’s confidence in Toyota may not have been tarnished. People are not buying a Toyota for just their looks, they are buying the Toyota brand because of the fact they are known to be a reliable and safe vehicle that can last â€Å"forever†. Chris Isidore says it best when he says† For years, Toyota Motor was the automaker that could do no wrong. Now it’s made a major mistake likely to have a lasting impact on the company (Isidore)†. Not only did the recall effect some of Toyota’s best selling vehicles it caused five North American plants to halt production which affected about 14,000 employees. To halt production to its vehicles is tough in an economy where there is strict competition. Erich Merkle, president of Autoconomy.com, an industry analysis  firm says â€Å"American rivals like General Motors and Ford Motor have similar vehicles to the ones recalled by Toyota, which are far more competitive than they’ve been previously. Loyal Toyota customers who decide to look at other offering are more likely to find something they like than they might have been in the past. Toyota fending off those rivals was going to be enough of a challenge without the safety issues.† Toyota does realize the negative impact this recall has is definitely not positive but they are determined to restore consumer’s confidence in their products. Many experts think that â€Å"the damage to the Toyota brand and the company’s sales may already have been done (Isidore)†. Toyota’s stock prices have gone downhill ever since the news of the recalls went public. Although the company is trying to resolve the issue with their floor mats and accelerator issues the media and customer dissatisfaction have put the company in a tight spot to respond to its troubles. This has cause competitors like Ford and Hyundai to react quickly and offer Toyotas customers incentives to trade in their Toyota’s for one of the competitor’s models. Some are even offering incentives of $1,000 and 0 percent financing to attract Toyota’s customer base. Every brand has its strengths and weakness. Toyota focused on a sub branch approach, in which most of its cars are linked to a single corporate brand. For Toyota that means that a problem with any vehicle at Toyota will not only affect sales of the effected model in question but to its entire inventory of vehicles. Therefore it comes as no big surprise that several of their vehicles were included in there recall. Audi was another car manufacturer that went through a very similar recall issue with accelerator problems. The overall impact this had on Audi was crucial. The resale value of the Audi 5000, which had been involve in a number of fatal accelerator accidents declined significantly as a result of the recall. This also had a snowball effect on other Audi vehicles such as a the Audi 4000, which lost significant resale value, and to a lesser extent also effected the Audi Quattro all due to the fact that they were a part of the same company. Any technical hitch with one car can als o mean problems with others when the auto world in known for using shared parts and technologies across multiple models. Another recall that that was notorious in history was with the Ford Pinto. This was definitely not one of the largest recalls because it only  affected about 1.5 million vehicles but some considered it the most dangerous. With this recall a driver could be subject to an exploding gas tank in the event of an accident. Initially Ford didn’t even want to recall these vehicles and would have rather dealt with lawsuits, which sparked a huge public outcry. In 1995 Honda another car manufacturer that is know for its reliability also had a recall on the Honda Accord and several other Honda and Acura models. This recall affected about 3.7 million vehicles. The main cause of the recall was the seat belt chassis, which had become either broken or unreliable in many cars. Chevy, Ford, and GM have also had their fair share of significant recalls throughout the years. These recalls affected millions as well. Most people realize that at one point or another something is going to wrong with their car. Repairs are to be expected and for the most part most cars and trucks will at some point have a recall. Recalls address safety problems, whether they are minor or major. Toyota’s recall was not so much a part had to be recalled but more of the fact they tried to blame it on the placement of a floor mat. When companies try to bush issues under the rug that’s when people remember. Although at this time the recall may affect Toyota negatively overall I think its customer’s will remain loyal. When bad things tend to happen, companies need the right strategy for talking their way out of a mess and avoiding a tarnished reputation. Choosing the best way to respond is not always easy but can make a difference towards the company’s survival. Toyota was aware there were issues with the accelerators and waited until they were in a crisis to resolve this issue. Toyota response to the recall not only affected its consumer base in the US but may have had the same negative impact with its Chinese consumers. One report indicated that â€Å"the large majority of Chinese car consumers (74 percent) are aware of Toyota’s present difficulties. Almost every two out of three of these consumers acknowledge that their confidence in the Japanese car maker has been affected (62 percent) and that the current recall practice degrades their image perception of Toyota. Among the owners, the impact is much less important though, as only a little less than one in every seven Toyota cus tomers strongly agree on a degraded image perception and decrease in trust (15 percent), compared with one out of  every four car owners of competitor brands (27 percent and 25 percent respectively) (WPP)†. The real question is did Toyota handle this situation correctly? The most important thing Toyota did was keep their customers informed, even if it was what some considered a delayed response. They issued recalls on all affected vehicles and they stopped production on their vehicles which shows consumers they are willing to correct the problem. They are also not willing to restart production or release any affected vehicles before the problem is correct. They have been working with dealers to manage the process of the recall as best as possible to limit customer dissatisfaction. With all of these positive approaches Toyota is trying to make, the concerns consumers still have are the overall reliability of Toyota and the potential effect this recall may have on the resale value of their vehicles. Several people have commented on their feelings towards Toyota after the recall. The majorities have been loyal Toyota customers that have owned one or more Toyota vehicle and the others have never owned a Toyota. Many of the Toyota customers felt that the media made a monster out of this recall and caused fear and panic in consumers. They also felt that the media created this perception that Toyota’s were no longer a reliable vehicle. Other people who never owned a Toyota feel that the Toyota name will be tarnished and that these problems were to be expected. If people really looked at the whole picture they may find these comments to be true. For several years car manufacturers have been sending out recalls. This is not the first one in history to happen and it will surely not be the last. Most industries anticipate for supply and demand. Toyota sales may have gone down since the recall but that is to be expected. Car industry forecasters do not anticipate that Toyota’s loss will cause a drop in overall demand. As long as Toyota continues to make new cars, people will buy them. May reports have indicated that people who initially thought about purchasing a Toyota before this major crisis would still purchase one. They realize that this recall is no different then other recalls that have happened through out history, with maybe the exception that Toyota did not act as quickly as the media and some consumers expected they should have. Toyota is a well known company. They will bounce back from this crisis eventually and may even try to offer its  customer’s incentives to purchase vehicles through one of their dealers that other car dealers may not be able to offer right now. Overall this recall just like anything else will pass and Toyota’s sales will be among the top again. People realize that the perception the media creates can sometimes have a long lasting impact, but then something else bigger will happen and things will return right back to normal for Toyota. It is a vicious cycle that we all live in. What people may lose now in resale value is really nothing major. People can actually benefit from this by purchasing a used Toyota at a lower price than what they would have had to pay years ago. Overall Toyota has a long history of loyal customer. This and the fact that Toyota is know for being a good quality car will allow it to bounce back from some mistakes they have made during this recall. Although its reputation may have been tarnished to some extent, they still have several loyal customers that will continue to purchase their vehicles through Toyota. This is just another obstacle they will get through. They will be able to use this incident to improve on their vehicle production and rebuild the Toyota brand and image.

Social Issues in Hedda Gabler Essay -- Hedda Gabler Essays

Social Issues in Hedda Gabler It has been suggested that Hedda Gabler is a drama about the individual psyche -- a mere character study. It has even been written that Hedda Gabler "presents no social theme" (Shipley 333). On the contrary, I have found social issues and themes abundant in this work. The character of Hedda Gabler centers around society and social issues. Her high social rank is indicated from the beginning, as Miss Tesman says of Hedda, "General Gabler's daughter. What a life she had in the general's day!" (Ibsen 672). Upon Hedda's first appearance, she makes many snobbish remarks. First, she turns up her nose at George's special handmade slippers. Later she insults Aunt Julie's new hat, pretending to mistake it for the maid's. Hedda seems to abhor everything about George Tesman and his bourgeoisie existence. She demands much more class than he has been able to provide her, for she was the beautiful, charming daughter of General Gabler and deserved nothing but the finest. As the character of Hedda Gabler develops, the reader learns that she has only married George Tesman because her father's passing away left her no significant financial resources, nothing but a respectable heritage. She tells Brack of her decision to marry Tesman: "I really had danced myself out, Judge. My time was up. ... And George Tesman -- he is after all a thoroughly acceptable choice. ... There's every chance that in time he could still make a name for himself. ...It was certainly more than my other admirers were willing to do for me, Judge." (Ibsen 684). Hedda needed someone to support her financially, and George Tesman was the only decent man to propose to her. She was forced to cross beneath her social class and marry this commoner in the hopes that he would make a name for himself as a professor. As for love everlasting, Hedda disgustedly comments to Judge Brack, "Ugh -- don't use that syrupy word!" Rather than having become a happy newlywed who has found true love, "Hedda is trapped in a marriage of convenience" (Shipley 445). Hedda was raised a lady of the upper class, and as such she regards her beauty with high esteem. This is, in part, the reason she vehemently denies the pregnancy for so long. A pregnancy will force her to gain weight and lose her lovely womanly figure. Hedda has grown accustomed to her many admirers; therefore, Hedda is ... ... Lastly, the tile itself represents the social theme of the drama. In using the name Hedda Gabler, despite her marriage to George Tesman, Ibsen has conveyed to the reader the importance of social class. Hedda prefers to identify herself as the daughter of General Gabler, not the wife of George Tesman. Throughout the play she rejects Tesman and his middle class lifestyles, clinging to the honorable past with which her father provided her. This identity as the daughter of the noble General Gabler is strongly implied in the title, Hedda Gabler. In considering the many implications of the social issues as explained above, it can not be denied that the very theme of Hedda Gabler centers on social issues. "Hedda Gabler is ...indirectly a social parable" (Setterquist 166). Works Cited 1. Ibsen, Henrik. Hedda Gabler. The Bedford Introduction to Drama. Ed. Lee A. Jacobus. 3rd ed.

Nutrition topic

This is one of the vitamins that form food supplement for man: others are Vitamin B1 [thiamin], Vitamin B2 [riboflavin], vitamin B3 [niacin], vitaminB5 [pantothenic acid], folic acid and vitamin B6 [pyridoxine]. These are important supplements that are required for the maintenance of metabolism in the organisms; they act as coenzymes and cofactors in various anabolic and catabolic reactions essential for the survival of cells, and the organism [1.4]. Of peculiar interest for this article is Vitamin B12. The reason for choice of this, among other things is because of the devastating medical cases including neural tube defects, irreversible Vitamin B12 neuropathy that may arise as a result of deficiency. It would be considered under the following headings: source, metabolism [structure, absorption, transport, biochemical function] and deficiency. SOURCE The vitamin is only available in animal sources. It is synthesized by microbes; animals acquire it by eating other animal foods, by internal production from intestinal bacterial flora. Its sources include food of animal origin, such as meat, fish, dairy products, liver. It does not occur in plant sources: cereals, fruits or vegetables [1]. METABOLISM STRUCTURE [1]: There are a variety of forms in which Vitamin B12 exists: as methylcobalamin in human plasma, as deoxyadenosylcobalamin in human tissue, as hydroxocobalamin for treatment, and cyanocobalamin in study of Vitamin B12 activity. All have the same basic structure: cobalt is at the centre of a corrin ring which is attached to a nucleotide. ABSORPTION: A normal diet contains a large excess of vitamin B12 compared with daily needs. B12 is combined with the parietal cell-produced glycoprotein, intrinsic factor. The IF-B12 complex binds to a specific receptor in the distal ileum called Cubilin. Vitamin B12 is absorbed here at the distal ileum. TRANSPORT: Vitamin B12 is absorbed into portal blood through the circulation from the intestine to the liver via the portal vein. Here it becomes attached to the plasma-binding protein transcobalamin II [TCII] which delivers B12 to the bone marrow and other tissues, where it is utilized for biosynthetic functions [4]. BIOCHEMICAL FUNCTION: Vitamin B12 is a coenzyme for two biochemical reactions in the body. First, it acts in the form of methylcobalamin as a cofactor for methionone synthase, the enzyme responsible for the conversion of homocysteine to methionine; methyl tetrahydrofolate is used as methyl donor during the reaction. Second, it acts as deoxyadenosylB12 where it acts as cofactor for the conversion of methylmalonyl conenzyme A to succinyl coA [4]. DEFICIENCY CAUSES: In this part of the world, perincious anemia is the commonest cause of Vitamin B12 deficiency [3]. In this condition, autoimmune reactions on the gastric mucosa cause production of antibodies against parietal cell products, intrinsic factor and its receptors; females are more affected and it is usually associated with other autoimmune conditions such as vitiligo, Hashimoto thyroiditis, thyrotoxicosis, etc. Other causes include malabsorption secondary to gastrectomy, congenital abnormailtiy of the IF, chronic tropical sprue, Crohn’s disease, intestinal stagnant loop syndrome such as stricture [4]. EFFECTS: Vitamin B12 deficiency causes megaloblastic anaemia [2]; it features include signs and symptoms of anaemis such as anorexia, easy fatiguability, pallor of skin and mucous membrane and malaise. Others are glossitis, angular stomatitis, purpura and lemon-tint jaundice. Severe Vitamin B12 deficiency may cause a progressive neuropathy affecting the peripheral sensory nerves and dorsolateral columns of the spinal cord [4]. The neuropathy is usually symmetrical and affects the lower limbs than the upper limbs. These changes are irreversible.

John Holt and Daniel Pink

John Holt and Daniel Pink Several writers, sociologists and educators are speaking out about the problems being experienced in modern schools. Violence seems to be increasing, students are leaving school ill-prepared to enter the workforce and test scores continue to fall. In attempting to fix our schools, several of these individuals have suggested that the solution is not to try to fix the school, but to abandon it altogether.Advertising We will write a custom essay sample on John Holt and Daniel Pink specifically for you for only $16.05 $11/page Learn More While it may seem to be a new argument, this question of abolishing the compulsory public school system has been around for decades. There are a surprising number of similarities found in the arguments of John Holt in his article â€Å"School is Bad for Children† published in 1969 and Daniel H. Pink’s article â€Å"School’s Out† published this decade. In his article, John Holt unsurprisingly argues th at school is bad for children. He starts his article by stating, â€Å"Almost every child on the first day he sets foot in a school building is smarter, more curious, less afraid of what he doesnt know, better at finding and figuring things out, more confident, resourceful, persistent and independent than he will ever be again in his schooling† (Holt, 1969). Holt makes his claim on the evidence that children first discover and then learn to use it all while making other important discoveries about the world and grasping highly abstract concepts. They do this â€Å"by exploring, by experimenting, by developing his own model or the grammar of language, by trying it out and seeing whether it works, by gradually changing it and refining it until it does work† (Holt, 1969). More importantly, children do this naturally, without anyone showing them how or telling them why. Although Pink does not directly address the condition of the child before he enters the classroom, he do es make a strong point of the skills needed to survive in the emerging economy. â€Å"Legions of Americans, and increasingly citizens of other countries as well, are abandoning one of the Industrial Revolution’s most enduring legacies – the ‘job’ – and forging new ways to work. They’re becoming self-employed knowledge workers, proprietors of home-based businesses, temps and permatemps, †¦ part-time consultants †¦ and full-time soloists† (Pink). This great shift in the way people do business requires a skill set highly similar to the natural abilities of the early child as described by Holt.Advertising Looking for essay on education?

Holt (1969) says children learn that learning is something done separate from living. Within the school setting, the child that he does not know how to learn and must adapt himself to the methods of the teacher. â€Å"In a great many other ways he learns that he is worthless, untrustworthy, fit only to take other people’s orders, a blank sheet for other people to write on† (Holt, 1969). According to Holt, the true lessons the child takes from school are to hide his curiosity, to be ashamed of thinking differently, to accept other people’s evaluation of him. â€Å"He learns that to be wrong, uncertain, confused, is a crime† (Holt, 1969). He learns how to find out what answers are expected and to give only those answers. He learns instead to be lazy, deceitful and how to pass blame. â€Å"He learns that in real life you don’t do anything unless you are bribed, bullied or conned into doing it, that nothing is worth doing for its own sake, or that if it is, you can’t do it in school† (Holt, 1969). He learns to turn himself off, to passively daydream an d to ignore the people around him. Pink would seem to agree. In listing the lessons children learned in school, Pink indicates that the results are mostly negative for the individual: â€Å"Kids learned how to obey rules, follow orders, and respect authority – and the penalties that came with refusal† (Pink). He also points out how nothing seems to have changed in as many as 40 years within the school setting or system with the exception of a computer or two within the classroom, but everything has changed outside of it. In addition, both authors argue for the abolition of the school system as it currently exists. Holt (1969) recommends abolishing the compulsory school law by arguing that these laws are no longer necessary to prevent adults from exploiting child labor. This would alleviate the anger and violence found in school classrooms and hallways and make a better learning environment for the kids that do want to be there. By making school a choice, the schools wo uld also have to make their programs something actually beneficial to the kids. Other options would be to make schools more of a learning field trip or bringing professionals into the classroom to talk honestly and frankly about their careers. Team learning is also recommended as a means of allowing children to take a more active role in their learning and to learn how to work with others. Holt also suggests getting rid of grades to allow children to assess and perfect their own work and getting rid of the established curriculum because children will only learn what is important to them anyway. Pink argues, â€Å"Compulsory mass schooling is an aberration in both history and modern society.Advertising We will write a custom essay sample on John Holt and Daniel Pink specifically for you for only $16.05 $11/page Learn More Yet it was the ideal preparation for the Organization Man economy, a highly structured world dominated by large, bureaucratic corporation s that routinized the workplace† (Pink). Now that we no longer live in an industrial economy and more people are finding it preferable or necessary to fend for themselves in creative ways, Pink says the system should change to foster these skills in our youth. Although the authors do not provide sufficient provision for the numbers of students who would not attend school if they didn’t have to or those who are actually safer at school than at home, they do make several valid points. It does seem as though the modern school system is nothing more than a system designed to create perfect factory workers, providing the ability for future supervisors and managers to excel and prove their worth. This requires workers willing to subsume their individual personalities, lose their natural curiosity and learn how to simply obey orders and ‘live’ at those times when their leaders did not have need of them. Pink provides convincing statistics that more Americans are f inding it necessary to live by the skills they had as young children as listed by Holt – curiosity, exploration, discovery, resourcefulness and independence. If America is to remain strong moving into the future, it must adopt a more effective education system that enables children to retain these skills and become the productive adults they can be.

Examples of Covalent Bonds and Compounds

Examples of Covalent Bonds and Compounds These are examples of covalent bonds and covalent compounds. Covalent compounds also are known as molecular compounds. Organic compounds, such as carbohydrates, lipids, proteins, and nucleic acids, are all examples of molecular compounds. You can recognize these compounds because they consist of nonmetals bonded to each other. PCl3 - phosphorus trichlorideCH3CH2OH - ethanolO3 - ozoneH2 - hydrogenH2O - waterHCl - hydrogen chlorideCH4 - methaneNH3 - ammoniaCO2 - carbon dioxide So, for example, you would not expect to find covalent bonds in a metal or alloy, such as silver, steel, or brass. You would find ionic rather than covalent bonds in a salt, such as sodium chloride. What Determines Whether a Covalent Bond Forms? Covalent bonds form when two nonmetallic atoms have the same or similar electronegativity values. So, if two identical nonmetals (e.g., two hydrogen atoms) bond together, they will form a pure covalent bond. When two dissimilar nonmetals form bonds (e.g., hydrogen and oxygen), they will form a covalent bond, but the electrons will spend more time closer to one type of atom than the other, producing a polar covalent bond.

Should my profession get license Essay Example | Topics and Well Written Essays - 250 words

Should my profession get license - Essay Example Hence, this is a high responsibility job. Therefore, should healthcare administration professionals get license? According to me, healthcare administration must be viewed as a managerial job equivalent to a managerial position in any other industry. Healthcare administration degree must be treated equivalent to a MBA degree. Yes, healthcare industry is dynamic and also sensitive due to its nature. But, healthcare administrators will not make an impact as that of a medical professional like a doctor or a nurse. Hence, a license must not be required to become a healthcare administration professional. A healthcare professional must have understanding of the law. Healthcare administrator with good understanding of the law will not only be able to protect himself but also their employers and even the patients (Gassiot et al., 2010). They must be tested to ensure that they are competent of doing the job and can handle the responsibility, But a license should not be mandatory to become a healthcare

International HRM Essay Example | Topics and Well Written Essays - 2750 words

International HRM - Essay Example The United Kingdom is also a very masculine society, which emphasises a cultural orientation toward achievement of success and exhibiting ambition and motivation in the professional world. This culture is also driven by a short-term orientation, meaning that future gains will be more eagerly sacrificed in order to achieve rapid results, especially in business. This is especially apparent in the professional relationship between the London Stock Exchange and UK investors, using quarterly results to help investors achieve instant gains. In order to fully understand the complexities, problems or opportunities for UK-based management expanding into France, Germany and Japan, it is necessary to outline the most prominent cultural characteristics that make up societal and professional values, beliefs and orientations. This essay describes the characteristics of the French, German and Japanese business cultures to critically assess what degree of adaptability will be required by the UK-base d organization upon new foreign business market entry. Research indicates that there are some distinct differences and moderate similarities to the UK culture that will determine the strategy direction for people management in these countries. Working with French employees For people management to be effective in France, the UK-based HR team must understand the fundamentals of what drives professional culture in this country. France scores highly on the power distance metric in Hofstede’s Cultural Dimensions framework. The notion of cultural power distance is defined as the level of inequality that is tolerated within a culture (Leng and Bothelo 2010). For instance, a less powerful figure (such as a subordinate employee) will be more indulgent and accepting of a more powerful figure (such as executives) maintaining disparity between ranking representatives of the business. Much of these cultural beliefs are driven by long-standing power distance between government and general society that was founded during the historical periods where France was governed by autocratic monarchy structures (Communicaid 2009). Powers in France, as it relates to business and government, have always been centralised in which business executives maintain the majority of control, thus creating organisational structures where decision-making authority is top-down rather than horizontal. French citizens further maintain a great deal of ethnocentrism, a belief in superiority of French culture and its rich history, which further supports acceptance and tolerance for power distance. For a UK human resources practitioner, there should be consideration of the high prevalence of tolerance of power distance. It is unlikely that French employees will be accustomed to working within decentralised business hierarchies that facilitate a great deal of team-working and horizontal problem-solving and decision-making. Therefore, there would be advantages for the UK manager that is attempting to facilitate more effective work processes and outcomes to take a hard approach to people management. Armstrong (2007) describes the hard HRM approach as an HR strategy that ensures more effective
