Marketing and Sales Essay

It has to pays debts and place orders of other departments inside its business. It tells the other departments of how much money is available to them and also gives advice. Such as if the ‘Marketing and Sales’ department of Tesco are going to spend 600 on a new TV advert and the finance department think that’s far to much money, then they would tell the department and would probably suggest something else if it is urgent. The financial staff are responsible for controlling the money and to make sure that departments don’t over-spend. All the senior managers receive help from the finance department when they are making major decisions on expenditure because the finance department don’t want them to make a huge mistake. This is because all bills have to be paid by the finance department. The level of sales is the starting point for setting the budget, which is why finance have to keep close links with ‘Sales’. Sales staff would expect finance to generate standard paperwork (invoices, statements etc) when they make a sale on credit. They would want finance to tell them if an existing customer is a bad payer and tell them the credit worthiness of new customers. Tesco’s finance department may receive a call from ‘Marketing’  asking if they want to offer extra discount or different conditions to a particular customer in order to secure a sale.  The employees’ wages or salaries are paid by the finance department. If anyone wants to ask or discuss anything about them then they have to contact the finance department. Some of Tesco’s stores may need some extra workers for particular jobs. Before they hire any, they need to ask the finance department if the business has money and that it can afford the cost. If the money is not available then the finance department may have to tell the ‘Human Resources’ department that no more staff can be hired. There can even be cases inside Tesco when the finance department have to tell the ‘Human Resources’ department to reduce the number of staff in order to save some money.  The ‘Administration’ department make so many phone calls and print out so many letters, they may be told by the finance department to make less international calls. If the printer breaks down the department may be told to buy a cheap one because there may not be enough money for a good one, or because the department may be over-spending. Finance has to pay for the goods that different functions have bought. The amount that each department spends need to be up to the agreed budget. Each department have to submit invoices for whatever it buys. The ‘Production’ department of Tesco may submit invoices for the raw materials it may have purchased. The finance department has to raise money for ‘Production’. A department has to be very careful that it does not go over budget because if it does it may face problems since its future orders may get rejected by the finance department. When goods from a department’s order arrive it is the job of that department  to check that everything is correct and is working properly. This is what the finance department expect from all the departments. However, if bills are not paid that department that ordered the goods won’t be blamed because they are dependant on finance to pay the bills. If some of the food items of Tesco have not been delivered because the previous bill didn’t get paid the production department as well as the customers would suffer because of the finance department. The finance department has to record the sales of products that Tesco sells. This shows that it is involved with sales too. The finance department also expects accounts to be kept by all departments so that it can be able to calculate profit or loss. Then it will be able to produce the ‘Profit & Loss Account’. This is how the finance function supports and works with all the other departments. It deals with the money matters of the other departments and if it makes any mistakes like forgetting to pay a bill etc, then there can be big problems which would stop the business from becoming more better and successful. These mistakes can create a bad reputation of Tesco even if it is just the finance departments fault. If the finance department wants to try and avoid these mistakes then it has to work with and support the other departments effectively.

Fantasy Story on crazy teachers

It was I who first came up with the thought that teachers at Pemberton High are crazy. In fact, some of them might not even be human! It wouldn't surprise me if I walked into the teacher's lounge one day and saw them slouching in large leather recliners peeling off their faces and talking in some strange alien language. For a start, there's my maths teacher Mr Henman. His real name is Jim Davidson, but due to his love of tennis he calls himself Mr Henman after Tim Henman. Call her anything but Mr Henman and watch out. His face goes all red and he looks like a six-foot brick wall with a bad attitude. His ring finger is about a foot long and when he wags it at you it's as though you're looking at a withering garden snake. He's over six feet tall and towers above the other teachers, even Mr Jones, our P.E teacher: And he's a big old lump! Mr Henman is a retired, yes you guessed it, tennis player! He'll pick you up by your ears and drop you on your head if you talk about Tim Henman or tennis in a bad way. As I said he's a retired tennis player. For sixteen years he tortured other tennis players and umpires alike with his skill and bad attitude. Now he spends his days torturing us. Mr Henman is pure crazy! Last week he asked the class if there was anyone who had not handed in their money for the school trip. No one raised their hand, but, I knew that my friend Timmy Anderson had not. He lives alone with his mum and sister and they sadly can't afford the trip. Mr Henman knew it too! I knew he was trying to make fun of Tim. â€Å"You'd better raise your hand,† I whispered, leaning close to Tim. â€Å"I'm not going,† he said. â€Å"Why?† Tim didn't answer but I knew. â€Å"Don't let him find out,† I said out of the corner of my mouth. â€Å"Otherwise, you know what he's like he'll say something to the whole school!† I could tell that Tim got nervous after that. He shifted in his seat and wouldn't look up front. Mr Henman goggled at Tim in the way a hungry lion would look at a raw steak. I could tell he had some diabolical plan brewing in his head. As the bell rang everyone went for lunch. I was walking with Tim and as we passed the teacher's lounge I noticed that the door was left partially open. This was it this was what I had been waiting for! This was my opportunity, I had to take it. I could sneak inside and listen to the teachers talking. I could prove that they were aliens or something worse. â€Å"Go on I'll catch up,† I told Tim. He jogged and caught up with my sister Nicole. I checked the hallway to make sure no one was coming. When I was certain it was safe, I strolled over to the door. I pulled it back a little and stuck my head inside. I couldn't hear anyone so I quickly slipped in and pulled the door to behind me. A walled coat rack separated me from the actual lounge. Still, it was quiet and I guessed that all of the teachers were down eating their lunch, peered around the corner and saw an empty room. As it was empty I decided that I would try again later and turned to go back out. That's when I heard someone coming. I was almost hysterical as I raced around looking for someplace to hide. I saw a door across the room and hoped it was another way out. I was still thinking when I heard the door open. I sprang across the room like a rabbit and in no time I was on the other side of the door. I pulled it shut and quickly realised that I was in a closet. It wasn't a solid door but one with wooden slats that ran across it. I could see out the door and hoped that whoever had come in wouldn't notice me. I almost fainted when the Headmaster and Mr Henman ambled into the room. Mr Henman sat at the little table and the head poured each of them a cup of coffee. They were only a few feet in front of me. The head sat opposite Mr Henman â€Å"Have you finished collecting for the school trip?† the head enquired. Mr Henman looked at him for a minute and then said, â€Å"Yes. All done. Everyone is going this year.† The principle took a sip of his coffee and said, â€Å"I hope this is not like last year. You can't keep paying for your kids to attend these things.† â€Å"It's not like that at all,† he said. â€Å"The kids raised money this year to help each other out. They're all paid up.† â€Å"You're sure?† he pressed her. â€Å"Last year you paid out of your pocket for almost ten kids, Jim.† â€Å"I'm sure,† he said. The head said, â€Å"Good.† He finished his coffee and left the room. Now I was really curious. What was he trying to pull? Was he trying to set Tim up for something? My ears were burning red. Mr Henman took something from his pocket and put it on the table. I squinted and saw that it was a small calculator, then he pulled out a pencil and a piece of paper. He worked something out on the calculator, wrote it on the paper and then replaced it back in his pocket. Then he pulled out his mobile. Mr Henman dialled a number and I was able to listen in on his call. â€Å"This is Jim Davidson,† he said. He looked around the room as if he was expecting someone. â€Å"Yes, I'm calling about my car payment this month. I'm afraid I won't be able to make it.† There was a long pause and then she spoke again. â€Å"I guess you could come get it at Pemberton High.† That evening as I rode the bus home, I saw Mr Henman walking from school. Earlier, I watched a man tow his car from the car park. And I noticed other things that I guess I just never paid attention to. He didn't have a nice coat like the rest of the teachers. Mrs. Bailey had a real nice pair of suede boots. Mr Henman sported a pair of old tennis shoes. He didn't look mad though, In fact, he had a smile on his face. I don't know if I'd ever seen him smile before. Maybe he was one of those people who weren't concerned about the number of possessions he owned? Maybe he was one of those people who was just happy to be living in such a prosperous area and working to help further children? Or maybe he was just a man with happy thoughts in his mind? I arrived home amazed by the look that had shone from Mr. Henman's face, as I saw him walking from school. Had that been nearly any other human being, but especially the adults that I know, they would have been in tears. Boy did I learn something about teachers that day. Especially Mr Henman. I learnt that he's not as crazy as I first thought he was, but a happy, contented man who was often misunderstood. I don't think I'll tell Tim, though. Sir wouldn't like that very much. He's not crazy, but neither am I!

Studies on the Economic Effects and Bans Essay Example | Topics and Well Written Essays - 750 words

Studies on the Economic Effects and Bans - Essay Example Most drugs are considered illegal since they have a way of causing significant side effects not only to the person abusing them but also the other people who directly interact with him or her. However, in any circumstance, cigarettes are still allowed whether an individual is hawking them or is just in their possession. There is a sort of regulation that has been put in force in purchasing the good. Age sixteen is the minimum age allowed for an individual to buy this particular commodity. However, it has been revealed by a number of researchers that greedy shopkeepers violate this policy by selling it before trying to find out the age or even identity of the buyer. Most individuals are always against smoking due to the irritating smell and are also scared of the health implications that accompany the act. When an individual begins the act, not only does he cause harm to himself but also results to environmental pollution and makes other people directly interacting with them to smoke. This is what is referred to as passive smoking and it can result to great harm to the internal body. As each year passes by, the smoking habit has greatly increased resulting to a proportional increase in passive smokers. Aware of the incoming disaster, the U.K government is in turn about to present to the queen a proposed bill that bans cigarette smoking in several public places. ASH, which stands for Action on Smoking and Health is a lobby for anti smoking whose mandate is to easily communicate with a market of their choice on the adverse effects of smoking. To achieve this, it closely works with â€Å"cancer research U.K†. Both companies professionally join forces to get rid of illnesses caused by smoking. ASH also worked with â€Å"you goo† company in carrying out prospective researches. It also issued ASH the research questionnaires. As a normal company, the main Aim of ASH it to ensure a global village free of tobacco harms. It can therefore be referred to as a public health campaigning charity organization. The ASH therefore is seen as an organization that doesn’t necessarily support the use of tobacco but is keen at dealing with the aftermath of its abuse. It can therefore be deduced that this organization is aware that completely banning cigarette smoking is hard n hence decides to focus more on how to deal with the aftermath. On the other hand, after taking my time to read an article written by Russell, I noticed called â€Å"The Facts† I noticed the authors artistic nature of pointing out the reasons behind the smoking ban. I noticed however that the studies selected by Russell take a one-sided trend and omits very significant points. In studying the smoking ban, one of the main agendas was to put solid proof to table as to why bans are relevant for business. It was discovered from a research made in California that there was a slight revenue increase of 5% after the ban was imposed. The study however fails to recognize the fact that the fact that at that very moment an overwhelming economic growth was being experienced by the country. The study also was keen at giving the exact number of businesses that strictly banned smoking. Several businesses were a part of the study yet most of them had put the ban under operation long before the study was conducted. The most affected businesses were the likes of bowling alleys, bars, bingo parlor, etc hence they were completely left out of the

The Death Penalty in the United States Research Paper

The Death Penalty in the United States - Research Paper Example Opponents also assert that the practice is overtly costly and racially biased while not realizing the intended outcome. Proponents think it is neither cruel nor unusual, quite the opposite, they think it fair and just. The objective of this study is to discuss the moral and legal concerns that literally are a life and death issue and is a key barometer when measuring a cultures collective conscience. The ‘eye for an eye’ faction not only accepts but insists that the death penalty be sustained and has supporting rational to back up their argument which will be covered comprehensively in this discussion. It will also take into account the opponents’ reasoning concerning why it should be eliminated along with the legal precedents concerned in an effort to achieve a comprehensive view of the capital punishment debate. Legal speaking, capital punishment is not unusual, by definition, unless one acknowledges the racial bias that exists throughout the justice system. The law cannot define whether it is cruel or not. Cruelty can be defined only by the collective social conscious of a society. The legal interpretation of the combined ‘cruel and unusual’ is open to debate, to some extent but the general usage of the word ‘cruel’ refers to vicious punishments that cause extreme pain. Most legal scholars agree that punishments that include body dismemberment or torture are unquestionably classified as cruel. The term torture was evidently open for debate during the past decade but the word means essentially the same universally; causing unwanted physical or mental anguish. The word ‘unusual’ is normally understood to mean going beyond what is an equitable application of punishment for an offense. For instance, if ten people were ticketed for a traffic violation and judge fined nine of them $150 but one was charged $1500, this punishment would be considered ‘unusual.’ Taken together in the phrase, †˜prohibiting cruel and unusual punishment’ signifies that the penalty should be apportioned equitably according to the specific offense committed. A ‘life’ prison sentence is an acceptable punishment but not if this punishment was imposed for jaywalking, that would be an obviously unacceptable sentence imposition because it is considered excessive and extreme given the nature of the offense. Excessive is a term that is also open to broad interpretation in both the legal and public realm. Some would contend, for example, that any amount of time imposed for ‘crimes’ such as the possession of drugs, prostitution and gambling should be interpreted as excessive consequently ‘unusual.’ The Supreme Court has on many occasions judged the merits of the death penalty and this action is interpreted as punishment which is cruel and unusual by the Constitution. The Court has consistently ruled the language of the Eighth Amendment does not prohibit t he death sentence as punishment. The Constitution was meant to be and is a malleable document, however. The judicial interpretation of the Eighth Amendment has evolved to some extent throughout the years. Therefore the Court could potentially reverse this standpoint at a future time as result of changing societal values. For instance, whipping convicted criminals was routine until the late Eighteenth Century. This practice is now considered to be inappropriate because society’s attitude changed to define it as a ‘cruel’ punishment. With respect to capital punishment, however, â€Å"

Education, Perception, and Gender Bias in Accounting Essay

Education, Perception, and Gender Bias in Accounting - Essay Example Therefore, its use should be recognised around the world. Without accounting, money would not have a definite manner of being properly utilised. This paper will review the education and bias that women often go through in relation to accounting as a field of study, also, as a career choice that they can make. As many fields in the market today, accounting and finance is considered a man’s field of expertise. This means that whenever there are opportunities to be filled in relation to accounting and finance, men always get the upper hand. Gender related discrimination and bias have found their way into the working field of accounting. The perception that is created here is that women cannot be accomplished accountants when the chance arises. This perception, as many women are out to prove, is flawed. They are out to prove that whatever men can do, they can do better. The education sector in many countries does not pay keen attention to the number of female accounting students. The number of female students in the accounting class cannot be compared to the number of male students in higher learning institutions, for example, universities and colleges. As seen above, accounting and finance is considered a field dominated by men. However, there are a growing number of female accountants and students in many countries. The encouragement they receive from different quarters like family and the government could be the cause of this rise.

What is happening with modern day China and its environmental issues Essay

What is happening with modern day China and its environmental issues - Essay Example Because of severe contamination of water, air pollution, and land degradation problems, life expectancy in the North of the country has decreased by 5.5 years (Dong, Liu, and Klein 164). Environmental degradation cost China about nine percent of its gross national income yearly. These threaten to undermine the growth of the country and exhaust society’s patience with China Government’s pace of reform. Further, this has threatened the Country’s stability, as the ruling party has to deal with increased public discontent and media scrutiny. The energy consumption of China has increased, reaching one hundred and thirty from 2000 to 2010. In 2013, Beijing witnessed a prolonged severe session of smog that the citizens dubbed it as â€Å"airpocalypse†; the hazardous particles concentration was forty times the level considered safe by the World Health Organization. Later in 2013, visibility in the Northern City of Harbin was shrank by pollution to less than fifty meters (Dong, Liu, and Klein 163). Research reveals that less than one percent of China’s five hundred cities sustain the World Health Organization’s air quality standards. In the degradation of the quality of air, coal has been the chief culprit. China is the greatest producer of coal in the world, and it accounts for approximately half of the global consumption. Equally, coal is also the chief source of the country’s sulfur dioxide accounting for ninety percent of the country’s total sulfur dioxide emissions and half of its particulate emissions. In China, coal is mostly burned in the North part of the country, and it avails approximately seventy percent of the country’s energy needs. Nevertheless, in 2011, coal emission levels from coal plants single-handedly contributed to almost two hundred and fifty thousand premature deaths. Similarly, air pollution in China is compounded by the country’s shocking urbanization pace. China’s government plans to move seventy; to seventy-five percent of

Film Making Essay Example | Topics and Well Written Essays - 1000 words

Film Making - Essay Example The popularity of the movement spread across the continent to discover the most unlikely host in the United States of America (Marie & Newpert, 2003, pp.1-7). The movement found ample support from the Czech Republic as well. This incredible film movement broke the barriers created by main stream commercial movies as well as transformed the darkish orthodox believes which had been carried over through the dark ages of feudalism, medievalism, & ecclesiasticism. Paris was perhaps the darkest city during the history of the Second World War. The German censorship on films & theatres meant that the French citizens could not get a taste of global cinema in any form what so ever. Barring a few exceptional directors like Jean Renoir & Rene Clair, the French audience had to quench their artistic aspirations by witnessing below par domestic films. For the younger generation of people like Eric Rohmer & Alain Resnais, this dearth in film shipment equaled to a hover cast of brutal fascist ideolog y. This taboo & restriction later turned out to be the source of inspiration for the new wave film makers. To this younger age band born around 1925-30, which would later consist of most of the directors of the new wave, films happened to be the centre of their universe & a sanctuary secluded from the ruthless realities of the outer world. (Marie & Newpert, 2003, pp.7-15) The end of the war & the liberation of France brought along an enormous desire for self expression, open interaction, & cooperation. Discussion of films became a part of the regular discourse. Film journals like the L’Ecran Francais, became an epicenter for great authors like Andre Bazin to familiarize their viewpoints & convey their unbridled panache for films. Bazin approached films as a true form of art, which deserved extensive scrutiny. His viewpoints often put him at loggerheads with the leftist writers who were hell bent on solely evaluating the political standpoints of a film (Marie & Newpert, 2003, pp.10-17). The pioneers, who vividly read film journals, now began to set up film clubs all over the French territory. Future stalwarts like Claude Chabrol, & Alain Resnais were precisely benefitted from these little film clubs. By witnessing hundreds of films they came face to face with art of film making. Eric Rohmer was another avid audience of the film clubs. He invited Rivette & Godard to join him & the trio began to write articles, journals, & discourses on world cinema. The most important film journal came out in 1951, & was named La Cahiers du Cinema, which was published by Andre Bazin & Jacques Doniol- Valcroze. Bazin was nothing less than a father figure to the young crop of film enthusiasts (Ostrowska, 2008, pp.126-138). Henri Langlois deeply believed that watching silent films was the best way to intermingle with the art of cinema. As an end result, the new wave directors had great faith in film makers like Charlie Chaplin, Buster Keaton, and D.W. Griffith & Erich von St roheim (Ostrowska, 2008, pp.126-138). The Italian neo realistic movement also had a huge impact upon the outcome of the new wave movement. The young French aspirants were

Since, the decision making process is an important practice in every organization and information system provides with the decision makers with information in the form of reports, researches and huge amounts of data is compressed into shorter forms and this helps the mangers to take decisions. System generated reports are widely used by all departments and it makes the work easier for managers. The flow of information is used by managers for the decision making process and the information systems mentors the information and make sure that it will flow smoothly and will not affect the decision making process.

Managers of information system and the computers plan research and coordinate the computer related activities of the organization. They coordinate with each other and determine technical and organizational goals. Although this requires a proper and strong understanding of the computer systems and the technology but formal reports and detailed information can be stored and developed and can easily be presented to the top management for the purpose of decision making. Information systems are also related to the hardware and the networking side but the core purpose is related to the management side only. The needs of the organization are identified at all levels and utmost importance is given to operational and strategic perspective. Competition is also kept in mind and that's why information systems are equipped with the state of the art technology to ensure that the organization won't lag behind its competitors.

IRAC Method Essay Example | Topics and Well Written Essays - 1000 words

IRAC Method - Essay Example Moreover, the method distinguishes the relevant laws that are used by the court with facts and justifies effective resolution (California State University, n.d.). Therefore, the paper intends to briefly discuss about the case of Reid v. Covert through analyzing an effective IRAC method. The discussion of the report will be highly focused on demonstrating the overall scenario including the problem, relevant commandments concerning the case as well as final outcomes of the court. Background of the Case (Reid v. Covert) The case of Reid v Covert (354 U.S. 1) can be considered as one of the major milestone cases addressed by the Supreme Court of the United States. The case had been conducted during the year of 1955 against Mrs. Clarice Covert for killing her sergeant husband in the military base. During the case of Mrs. Covert concerning her suspected offense, a jurisdiction agreement had been observed to be present between the United States and the United Kingdom which further authorize d the military court of the US to take adequate jurisdiction right over the crime conducted in the UK military base by servicemen of the US or by their dependents (Cornell University Law School, n.d.). IRAC Method Assessment Issue The case of Reid v. Covert can be observed as a major decisive case adjudicated by the US Supreme Court which incorporated principle constitutional issues. The case was documented in No. 701, October Term, 1955 in which Mrs. Covert had been convicted for killing her husband who was a sergeant in the US Air Force. The incident had taken place at an airbase located in the United Kingdom. According to the case, it has been observed that Mrs. Covert was not a part of the armed services and she was live in the military base with her husband during the incident period. Moreover, the trial related to the issue was conducted based on the charges selected by the personnel of the Air Force. The major issue that emerged from the case was regarding a clash between the Constitution of a country and an enacted treaty. Raise of constitutional issue was the major concern within the case. The issue raised a question regarding the role played by the military under the governmental system. The issue also raised the Bill of Rights related concern. In this case, for the first time, after the implementation of the Constitution, wives of any soldier had been deprived of trial prior to a court-martial (Cornell University Law School, n.d.). Rule With regard to the case of Reid v. Covert, it has been recognized that the rule of law applied was Article 118 under the Uniform Code of Military Justice (UCMJ). With reference to this article, court-martial took place which comprised officers of the Air Force. Through the court martial under the Article 2 (11) of UCMJ rule was affirmed over Mrs. Covert. Any treaty or provision agreed upon by the US comes under consideration of the article and are regarded as rule enacted beneath international law. Moreover, all indi viduals employed by or serving with or accompanying the military forces devoid of the continental periphery of the US are also considered. The other rules of law relate to the verdict provided regarding case by Air Force Board of Review, 16 CMR 465, which was reversed by the verdict presented by the Court of Military Appeals. Furthermore, with regard to the case Fifth as well as Sixth Amendments of the Constitution were of significance (Cornell University Law School, n.d.). Analysis It can be analyzed with the regard to the case that the counsel in authority for Mrs. Covert argued that she was in an insane state of physical condition while she murdered her husband. However, the military tribunal deemed

Martha Stewart's Case Analysis Essay Example | Topics and Well Written Essays - 1250 words

Martha Stewart's Case Analysis - Essay Example The company’s stated market is ‘as big as everyone who has a house.’ The company is shown to have four segments which are divided into three platforms in order to leverage investments. There is the Omnimedia platform which is divided into publishing (focusing on the Martha Stewart Living (MSL) magazine, Martha Stewart Weddings as well as a selection of special interest magazines and books and a New York Times column) and television (focusing on the Martha Stewart Living television series, From Martha’s Kitchen, prime time specials and Christmas events). There is also the OmniMerchandising platform (focusing on Martha Stewart branded lines ranging from the Martha Stewart Everyday line to the Martha Stewart Home line, distributed principally through Kmart and Sears respectively) and the Internet/Direct Commerce platform (focusing on Martha by Mail catalog and the marthastewart.com website). Stewart herself is the driving force behind the company, maintaining control over the company following privatization with 60% control of shares and 96% control of votes. She maintains close relationships with her female dominated board of directors while her family also play an important role in the business. The root problem of the report is that it is difficult to assess the value and long term future of a company which is based around a personality. This is because the company could be seriously adversely affected by a change in public opinion with regards to Martha Stewart herself. This problem exists because the company has become a personality led brand. It is therefore extremely difficult to predict how public opinion will react to the personality in the future if their perceived strengths are threatened. Examples in the case study include criticisms of Stewart as being difficult to work with, as setting unreasonably

History of Modern Philosophy Essay Example for Free

History of Modern Philosophy Essay 1- How, and with what success, does Hume deal with the apparent anomaly of the missing shade of blue? In A Treatise of Human Nature, Hume attempt to rid 18th century moral philosophy of what he considered to be meaningless and vacuous concepts underlying our theory of knowledge be it metaphysical arguments or hypotheses seemingly formulated from the mere imagination of many philosophers. Influenced by the emerging trend of empiricism and naturalistic science like Newton and Locke, which Hume owed much of his basic principles from Hume presented the Treatise as an attempt to introduce experimental methods of reasoning into the area of moral philosophy. In the first book of the Treatise, entitled Of the Understanding, Hume devoted the first part Of the Origin of our Ideas for explaining the basis of his philosophical system that appeals on the similar empiricist approach as that of Lockes. However, curiously, Hume had cited an explicit counter-argument the problem of missing shade of blue that could invalidate his whole philosophical system that is based on this central principle. Even more puzzling is Humes complacency with this problem, and although he considers the problem as singular and exceptional, he fully admitted to this counter example and did not try to resolve it. Yet, this case merits a deeper investigation, and it is this essays attempt to see whether his apparent complacency with the missing shade of blue would have any effect on the strength of his philosophical system, and other attempts to render this problem irrelevant. The problem of the missing shade of blue by Hume is as follows: suppose a man who is well acquainted with colours for thirty years and has seen all the colours in the set of possible colour spectrum, except for one particular shade of blue. Then, he is presented with a full spectrum of the shades of blue, from the darkest shade to the darkest, all except the one particular shade in which he has not yet encountered. It is then conceivable that this man would be able to produce this single missing shade of blue. The problem of this lies in the basis of the empiricist doctrine at which Hume is following, namely, that all ideas must be preceded by experience, yet, in this example, it is demonstrated that it is possible for an idea to precede sensation experience, as the man is able to produce the idea of the missing shade of blue without having first encountered it through his senses. At this point, I would like to elaborate more on Humes theory of mind and the origin of ideas as that would clarify why this example is so damaging to Humes system. As stated before, Humes project can be put into a general label of empiricism, which is a belief that all knowledge comes from experience. Much of his line of argument resembles that of Lockes, another prominent empiricist. Hume even borrowed Lockes key terminology to a certain extent, with terms like ideas and impressions. Locke believes that ideas are whatever the mind perceives in itself, or is in the immediate object of perception, thought, or understanding, as when one perceives, thinks, or understands, the ideas are before the mind. This limits all ideas to be originated from experience (perception), and also shows the connection between thought and perception and their interchangeable nature. The ideas can be divided into ideas of sensation (touch, smell, sight, etc.) and ideas of reflection (fear, happiness, sadness, etc.), which can then be separated further into simple and complex ideas, where complex ideas are derived from simple ones. Hume follows this line of argument with some modifications. He claims he restores the term ideas to its original sense by classifying the objects the mind is perceiving as perceptions, not directly as ideas as Locke have used, and from perceptions he then distinguished them into impressions and ideas, where they differ in degree, as impressions are more vivid and forceful before the mind, such when sees a colour, and the ideas are more faint, such when one thinks of a colour after having the impressions of it. Hume then makes the distinction of simple and complex ideas, and by introspection, Hume demonstrates that one can think of any simple ideas and then find corresponding simple impressions that are exact copies of each other, and one can do this with any conceivable simple ideas. Complex ideas are different in that they are composites of simple ideas. And with this experiment in introspection, Hume then postulates his first thesis, That all our simple ideas in their first appearance are derivd from simple impressions, which are correspondent to them, and which they exactly represent. We may call this the Copy Principle, as it simply states that every simple idea is a copy of a corresponding impression. One of the most important components of this thesis is the fact that its a genetic one in that it shows the origin of ideas as following from impressions as impressions to be the cause of ideas. Again, this is proved by the constant conjunction of simple impressions preceding simple ideas, which one can do to every simple idea one may have. Another support Hume gives is that of a man born defective of certain perceptive organs, hence, missing certain impressions (e.g. sight or sound), one would not have any ideas of those corresponded with the impressions, for it is evident that deaf people also have great trouble speaking. The genetic component is important in that they validate the empiricism doctrine on the reliance of experience. Anyhow, now we can see how the problem seems to defeat the purpose of this thesis. Moreover, a counter example, from a logical standpoint, one counter example is sufficient to turn an argument invalid. So why did Hume not deal with this problem? We may try to take it as Hume claimed the problem to be a singular case where it is not worth investing time on. Being a singular case, one may have to take the argument in closer inspection. Hume states explicitly that the man in question may have enjoyed the sights for thirty years and perfectly well acquainted with all the possible colours except one, and that may be the attempt by him to restrict this to some specific scenario. It is implicitly embedded in the counter example that the subject of this example must be well acquainted with all the colours, such that one can make up colours in ones mind, much like how only musicians of a certain skill level can sight read music. Thus, it appeals to some amount of experience such that one may be bound to experience, habits, or personal background. Yet, when given further consideration, this seems to be invalid as well, as these restrictions do not seem to hold. As far as experience go, a child who does not know what turquoise mean does not necessarily have an idea of the colour turquoise. So this case is certainly not an exceptional case and Hume had not dealt with it satisfactorily. Yet, Humean scholars have tried to find solutions for this problem and some even disregard it as a problem altogether. Firstly, the first objection to this counter argument is that there is no way to test whether the person in question does in fact have an idea of the missing shade of blue before seeing the missing shade or not. There is a great difference between being able to spot a missing spot in a complete spectrum of blue, and being able to produce an idea of the shade of blue without first encountering the impression of it. If ones sees a constant change in shade from, lets say blue-0 where it is darkest to blue-255 where it is the lightest shade, then if there is one shade of blue missing, it would be quite noticeable as the mind notices the jump in gradual and constant change, but it does not follow that one could create an idea of that missing shade. To test this is also impossible, as if one is to reproduce colour, it still does not follow that he produces the idea since he would only be mixing the existing colours to brighter shades, and thus, after finishing mixing the colour, one then has the idea of the colour following the impression. All other ways of testing is equally futile because they all involve exposing the subject to the missing impression one way or another. Alternatively, if we look at the thesis again, and instead of taking it as a genetic form of the argument that Hume meant it to be, and instead, modifies it slightly to a more analytical empiricism form. Humes thesis on the theory of mind, upon closer inspection, can be taken as a form of meaning empiricism, in the sense that ideas to him are the same as different thoughts, which are different kinds of concepts, which is linked to when one understands something in a linguistic sense one is linking the word with the meaning, or the concepts associated to the word. Hence, if we think of the initial genetic content of the thesis, that impressions strictly precedes ideas, we may relax it slightly in favour of the analogy to meaning empiricism and forget its genetic form and instead formulate the following thesis: that all simple ideas must have corresponding conceivable and encounterable impressions. By doing this, we are no longer faced with the problem of the missing shade, since it is perfectly possible that the subject would be able to encounter this particular shade. Lastly, from a personal view, I see the problem of the missing shade of blue as not a problem at all, but Humes mistake lies in classifying colours as simple ideas. It is true that the impressions of light blue might very well be different than dark blue, so to speak, but to use Humes method, it is possible to separate using our imagination the components light and dark from blue. Thus, it is the impression of blueness which is a simple impression, combined with the impression of light and absent of light that combine to give this multitude of shades of colours. Take this example, suppose some neutral shade of blue, lets number it blue 124, were put somewhere with light, you will be able to see blue 124. However, lets say for some reason, the room becomes lighter, certainly, the shade of blue 124 would have changed to some lighter shade of perhaps blue 200. If we vary the light in the room from darkest to lightest, it is then possible to observe from the darkest to the lightest shade of blue likewise. One may argue that the colour can be calibrated to some objective criteria, perhaps the ratio of pigments of colour blue of some sort, yet, that does not matter since all that matters to Hume is indeed only impression. Furthermore, using this example, we can also say that perhaps the subject of the experiment may have in fact encountered the particular shade of blue sometime before without acknowledging it. Conclusively, although Humes treatment of the missing shade of blue is very limited and very complacent, it is perhaps Humes own mistake for considering such example a problem, rather than the problem itself being a threat to his theory of origins of ideas.

Energy & capability Essay Example for Free

Energy capability Essay Energy has been defined as the capability to produce an effect, it can be stored within a system and can be transferred from one system to another and use it in our everyday life. Generally, countries around the world benefited most their energy consumption from oil. Unfortunately, oil crisis affects every nation since producers and sellers monopolize its price as well as its production but apparent drawbacks are expected due to depletion of oil reserves and environmental pollution. The United States merely consumes one-fifth of the world’s oil produced and 35% of it utilize for transportation hence oil importation ought to resolve through alternative energy utilization. It is good to hear that researches and new technologies of alternative energy production and usage have been recently prioritized by the government. There’s only one way to insulate the US from the corrosive power of oil, and that’s to develop an alternative energy resource that’s readily available domestically: hydrogen . Hydrogen is the simplest, most abundant element and it is lighter than air and can be found in the atmosphere in an insoluble substance gas. It is only available on earth in a compound state like water (H2O), coal, petroleum and methane (CH4). It has the highest energy content of any common fuel by weight (about three times more than gasoline), but the lowest energy content by volume (about four times less than gasoline), an energy carrier and derivative of other chemicals that can be produced from a variety of resources (water, fossil fuels, biomass) . Hydrogen can be extracted with no environmental pollution effects through â€Å"steam reforming in which natural gas reacts chemically with steam to produce hydrogen and CO2, electrolysis which splits water into hydrogen and oxygen and the latest discoveries from cultured microbes that emits hydrogen , all require expensive financial support from the government. The fuel cell is an electrochemical devise that can continuously convert chemical energy into electrical energy of power as long as fuel and a reactant are supplied hence chemical reaction of hydrogen and oxygen in a fuel cell create electricity leaving only water as byproduct unlike internal combustion engines that also generate carbon monoxides hazardous to man and environment as well. Hydrogen often described as the perfect fuel for it does not explode, environment-friendly exploitation and exhaustible major reserve of water will never run out of hydrogen however, considerable amount of energy is needed for steady production of hydrogen. The higher temperature fuel cells can reform natural gas for instance, gaseous hydrogen must be compressed and stored in tolerable high pressure tank to hold enough fuel for travel while liquid hydrogen demands more than -4000F for refrigeration both require high temperatures for fuel to recuperate. Adoption of hydrogen technology should settle first the hydrogen fuel-tank problem, mass production of fuel cell vehicles, alter fueling infrastructure to hydrogen, intensify hydrogen production and public campaign to sell the hydrogen economy . Indeed, importation of fuels can be minimized plus pollution free environment consequently upsurge economic growth. BIBLIOGRAPHY Richard Sonntag Claus Borgnakke.

Neurotransmitter and Hormone Receptors

Neurotransmitter and Hormone Receptors 1) Transcription of DNA and translation into protein are tightly regulated in Eukaryota cells. Give an account of the key steps involved. Gene expression is under continuous regulation. This regulation is differentiated between Eukaryotic and Prokaryotic organisms, especially due to matters of complexity. In Prokaryotic organisms the regulation of gene expression is happening only at the stage of transcription and includes one stage. On the other hand, the regulation of gene expression in Eukaryotic organisms is happening not only in transcriptional level, but also at post-transcriptional, translation and post-translation level (Latchman 2007). The figure on the right shows the steps of gene expression that can be regulated. In case where the regulation of gene expression happens in transcriptional level, then the levels of cytoplasmic mRNA and nuclear RNA should be paralleled. On the other hand, in case a gene is being transcribed in the same manner in all tissues, there will be a difference in the majority of tissues between the cytoplasm mRNA and RNA, due to post-transcriptional mechanisms. As a result, in order to distinguish post-transcriptional and transcriptional regulation the first approach is to see if there are changes between the RNA levels in the tissues (Latchman 2007). Initiation of transcription In many cases where there is an increased level of transcription, this results from a high level of transcriptional initiation mediated by RNA polymerase responsible for initiating the process. This means that in a tissue that occurs an active transcription process, the RNA polymerases will be moving beside the gene continuously, and thus increasing the rate of transcript production. In contrast, in tissues where a gene is transcribed at low levels, the initiation of transcription will not be so apparent and the level of transcripts will be significantly low (Latchman 2007). Elongation Except of the initiation of transcription which seems to occur in the majority of the cases, there has been demonstrated that the regulation can also happen during at a post-initiation level by producing a shortened RNA than the full length one. In this case, the transcriptional control seems to happen by blocking the elongation of a newly formed transcript (Latchman 2007). DNA elements The expression of protein-coding genes is regulated also by specific DNA elements, which are located usually upstream of the initiation site of the gene. These DNA elements can influence positively or negatively the transcription of a gene. For example, DNA sequences such as insulators and silencers, suppress the genes transcription (Latchman 2007). Transcription Factors The transcription factors are also important modulatory elements of transcription. The binding of specific transcription factors on the DNA, can either activate or suppress gene transcription (Latchman 2007) . Although so far we discussed the transcriptional control of gene expression, which corresponds to the most abundant transcriptional control mechanism, there have been cases where even though the transcription rate of a gene doesnt change, changes in the synthesis of specific proteins have occurred. This control mechanism occurs between the translational and transcription control and includes splicing of the nascent mRNA, alternative splicing, and regulation of RNA stability. The splicing of the RNA is the process in which the protein coding regions are encoded by exons, after removing the intervening sequences which are named introns (Latchman 2007). The alternative splicing, includes the differentiated processing of RNAs in order to produce different RNA variants (Black 2000). The translational control of gene expression, corresponds to mRNA regulation and is also a very important regulatory stage. In the same manner as transcriptional control, translation can be affected either positively or negatively by altering the levels of specific translation factors, and most of the times it happens at the initiation of the translation process due to differences in the 5 untranslated region of the mRNA. During translation, the 5 un-translated region contains an AUG triplet of bases which is important to be located in a favorable context. This means, that if the ribosome is incapable of recognizing this triplet, then the initiation of translation is inhibited. For example, in a situation which is called leaky scanning, when AUG codons are located upstream, the ribosome has a difficulty to recognize them (Wickens et al. 2000). Furthermore, except of the recognition of the AUG codon, other coding regions seem to play an important regulatory role. For example, some frequencies which are located in the open reading frame of the mRNA (ORF) seem to cause a frameshift at a specific triplet both in viral and mammalian mRNAs (Wickens et al. 2000). Finally, another regulatory element of gene expression includes the post-translational control. This category composes of all the mechanisms that act after translation by modifying the protein levels. Such a mechanism is ubiquitination, which will have as a result the degradation of the ubiquitinated protein in the proteasome (Wang et al. 2013). In conclusion the transcription and translation are highly regulated processes and this take place due to the complexity of Eukaryotic cells, since strict regulation usually corresponds to high complexity. 2) Discuss the role of microtubules and their motor proteins in the motion of cilia and flagella. Microtubules are important elements for various cell movements, such as the chromosomal separation during mitosis and the motion of flagella and cilia. This movement, which happens along microtubules, is highly dependent on proteins that use energy from ATP hydrolysis in order to produce force and movement. These proteins are members of the kinesin and dynein families (Alberts et al. 2002). Cilia and flagella are plasma membrane projections dependent on microtubule formation, and are important for the movement in various eukaryotic organisms. In bacteria, the flagella structures are different from the eukaryotic flagella (Alberts et al. 2002). The movement of these structures has been extensively studied by using animal models, especially sea urchin models which appears to be a very powerful system for flagellar motility. Furthermore, the first scientists to observe this sliding mechanisms driven by dynein across the microtubules, were Summers and Gibbons by using dark-field microscopy (Hirose Amos 2012). In eukaryotic organisms the flagella and cilia are highly similar structures. Firstly, flagella are mostly found in sperm and many hair-like cellular projections with a core composed of microtubules (Cooper 2000). With their rolling motion they permit the cells to swim through liquid media. The cilia, are usually shorter than flagella but their organization tends to be similar. Their beating motion is like the breast stroke of the swimmers, and the cycles of adjacent cilia are quite asynchronous, thus producing the characteristic effect that can be observed through microscope (Alberts et al. 2002). The movement of both each flagellum and cilium is produced by the bending of each ones core, which is specifically termed as axoneme. The axoneme is a structure that is composed of microtubules in conjunction with their associated proteins in a regular and specific pattern. This pattern is composed by nine doublet microtubules which are fused together to surround a pair of microtubules. Th is formation is also known as the 9+2 pattern and is represented in the following picture (Cooper 2000). This type of arrangement is commonly seen in the majority of eukaryotic flagella and cilia forms. The length of these microtubules extends along with the length of the axoneme which can reach the 200 ÃŽÂ ¼m. At specific positions along the distance of microtubules, are located accessory proteins, providing with this a way a cross-bridging between the doublet microtubules. These molecules are dynein proteins, and are located around the perimeter of the axoneme (Cooper 2000). Dynein is a very large molecule (2000 kd), consisting of three heavy chains in conjunction with a variable number of intermediate and light polypeptides that have a weight ranging from 14 to 120 kd (Cooper 2000). The heavy chains are forming a globular domain which binds ATP and is responsible for moving along microtubules. The intermediate chains are responsible for the assembly of the dyneins. The light chains form two distinct groups, in accordance with the molecules that are related with. For example the first group is associated with the heavy chains, while the second group with the intermediate chains. In the cilia and flagella, there is also another specific dynein group, the intraflagellar transport (IFT) dynein, which is important for the association and disassociation of these organelles, and also have transport properties of either membrane proteins or even the IFT themselves (Hirose Amos 2012). The ciliary dyneins, are composed of a different set of arms, the outer dynein arms and a more complex set of inner dynein arms. Each one of this structures plays a different role in the ciliary movement. The outer dynein arms are responsible for the production of the majority of the force required for the ciliary movement, while the inner dyneins, are mostly providing a precise control of this movement (Hirose Amos 2012). Another important feature of the cilia and flagella, is that the minus ends of each microtubule are anchored in a structure which is named basal body. This is highly similar to the centriole, and is necessary for the arrangement of the axoneme microtubules. Each one of the doublets located in the outer part of the flagella or cilia, is formed by the extension of two of the microtubules of the basals body triplets (Cooper 2000). The movement of cilia and flagella is caused by the relative sliding of outer microtubules, driven by the activity of axonemal dynein, and the mechanism is represented in figure 3. The dynein bases attach with the A microtubules while the head of each dynein attaches with the B microtubule. With the green color is represented the nexin link, which binds the microtubules in the axoneme. When the one doublet of microtubules, bends along with the other one, the resulting movement is bending, which is the source of the beating movements of cilia and flagella (Alberts et al. 2002). Scientific evidence suggests that upon ATP hydrolysis the dyneins change their conformational state (Hirose Amos 2012). 3) Describe the most important classes of molecules that participate in common signal transduction pathways In signal transduction pathways, extracellular signals such as hormones or other molecules are registered by membrane receptors and the signal is being transferred inside the cell by a set of reactions. This signal transduction can be mediated by two distinct mechanisms. The first one includes the use of receptors, and other proteins including enzymes. The second one contains a set of molecules which are known as second messengers, that regulate the intracellular signaling (Boon 2009) . The intracellular second messengers, are signal molecules that reach their target by diffusion. They can be divided into two different groups, those with a hydrophobic character (diacyl glycerol or phosphatidyl inositol) and the hydrophilic ones. The hydrophobic messenger are located on the membrane and they can reach the proteins located on the membrane by diffusing through the plasma membrane of the cell. The hydrophilic messengers are located in the cytoplasm and their targets are located in the cytosol as well (Boon 2009). The most important second messengers include the cAMP, cGMP, inositol phosphates, calcium ions, diacylgrlycerol and phosphatidyl inositol phosphates. 3-5 cyclic AMP (cAMP) Is among the most important second messengers and regulates a variety of cellular functions, such as glycolysis, muscle contraction and ion transport. The intracellular concentration of cAMP is regulated by two factors, the adenylyl cyclase and the phopshodiestarases. The former is important for the cAMP synthesis while the latter for its degradation. The activation of adenylyl cyclase is dependent to G-protein coupled receptors and involves the participation of GÃŽÂ ± and GÃŽÂ ²ÃƒÅ½Ã‚ ³ proteins. The degradation of cAMP mediated by cAMP phosphodiesterases, which are being regulated by Ca2+/calmodulin and also by phosphorylation (Boon 2009). In the majority of the cases, the target of the high cAMP concentration is the activation of protein kinases A (PKAs). Initially, in the absence of cAMP the PKA is organized as a tetramer, with two catalytic and two catalytic subunits, and the protein kinase is inactive. When cAMP concentration is increased by adenylyl cyclase, leads to the binding of two molecules to the regulatory subunit and the tetramer dissociation and activation of PKA (Boon 2009). cGMP In the same manner with cAMP, the 3-5-cGMP is extensively spread in the intracellular space. Like in the case of cAMP , the cGMP is formed by guanylyl cyclase from GTP. The cGMP can activate cGMP-dependent protein kinases, after binding to specific locations. In contrast to the PKA kinases, the activation of cGMP-dependent protein kinases is dependent to only one protein chain of these proteins. Specifically, the binding of the cGMP to the regulatory domain of the protein, activates it and permits phosphorylation of other substrates (Boon 2009). Inositol Phosphates The inositol containing phospholipids located in the plasma membrane, are the starting points for the production of many inositol messengers as a response to extracellular or even intracellular signals. The inositol phosphates are important players for the regulation of phospholipase C, which is a very important enzyme in the metabolism of phosphatide inositol. Another important function of these phosphates, is the recruitment of Ca2+ ions that are inside storage organelles, such as mitochondria. The calcium ions are among the most ubiquitous targets of second messengers, and regulate a vast array of actions (Boon 2009). Calcium ions The calcium ions can have a regulatory character in many ways, according to the time, frequency and amount of release rate. This feature, explains the complexity of Ca2+ signals. Still it is not understood how oscillatory calcium signals are regulating various processes. It has been suggested that CaM kinase II participates in the formation of repetitive calcium signals. The high intracellular concentration of calcium is temporary and usually a local phenomenon. The cell contains a variety of transport systems, which can transfer the calcium ions inside the storage locations. These transfer mechanisms are Ca2+ ATPases, which transfer calcium against the concentration gradient. Another mechanism, is the sodium-calcium exchange proteins which are mostly apparent in muscle cells (Boon 2009). Diacylglycerol and phospatidyl inositol phosphates The diacylglycerol is being produced by the metabolism of the membrane phosphatidyl inositol phosphate, after the effect of two distinct enzymes, the PLCÃŽÂ ³ and PLCÃŽÂ ². The diacylglycerol (DAG) is then responsible for activating the protein kinase C, which plays an important role in cell proliferation through phosphorylation of various substrate proteins (Boon 2009). Except of DAG, the metabolism of phosphatidyl inositol diphosphate, produces the inositol triphosphate, which increases intracellular calcium levels by binding to specific receptors (Boon 2009). Conclusively, signal transduction is a highly regulated mechanism, which permits the transmission of an extracellular signal inside the cell, and a subsequent cellular response. Among the most important molecules that are participating in this process, we distinguished some members of the family of the second messengers, such as calcium ions, diacyl glycerol and phosphatidyl inositol. 4) Describe the steps of neurotransmission. The process of neurotransmission can be divided into five distinct steps. The first includes the synthesis of the neurotransmitter, the second the storage of the neurotransmitter into transport vesicles, the third the influx of calcium and exocytosis of neurotransmitter, the fourth the binding of the neurotransmitter at the postsynaptic membrane and the fifth the deactivation of the neurotransmitter. The low weight neurotransmitters are synthesized in the cytoplasm of the cell, where enzymes act and convert them into mature neurotransmitters. These enzymes are produced in the neuronal cell body and are transferred to the presynaptic terminal via the slow axonal transfer system. When the new transmitters are synthesized in the cytoplasm, certain mechanisms need to follow for transporting them to the synaptic membrane. On the other hand, the neuropeptides which is the other category of known neurotransmitters, are produced in the neuronal cell body, and need to be transferred a long distance in order to reach the site of secretion. For this reason, they are transported from the soma of the neuron to the presynaptic terminal with the fast axonal transport (Hyman et al. 2009). The small-molecule neurotransmitters, such as acetylcholine and amino acids, are stored into vesicles of 40-60 nm diameter. The primary characteristic of these vesicles, is that in electron micrographs they appear with a clear center area. The storage, requires specific proteins which are located in the membrane of the synaptic vesicles in the presynaptic neuron, the vesicle monoamine membrane transporters (VMAT). In contrast to the small-molecule neurotransmitters, the neuropeptides, are stored into synaptic vesicles with a larger size (90 to 250 nm). In electron micrographs, they seem to have a center relatively more dense than the synaptic vesicles of the small neurotransmitters (Purves et al. 2001). After the influx of calcium into the pre-synaptic cytoplasm, it begins the process of neurotransmitter release. The first step of this exocytosis, includes the docking of the synaptic vesicle membrane at the active zones plasma membrane. The second step is priming. This corresponds to an ATP dependent maturation of the synaptic vesicles that are being docked in the membrane of the active zone but cant be induced by Ca2+. The result of this maturation, is that the primed vesicles can immediately release their content after a Ca2+ influx. The third step of this process includes the fusion of the synaptic vesicle with the presynaptic membrane, which allows the exocytosis to happen. In this step, the function of the protein synaptotagmin is of high importance, since it senses the levels of Ca2+ and regulates with this way the fusion of the vesicles. The final step of this step includes the quantal release of the neurotransmitter with a mechanism of exocytosis. The exocytosis is synchroni zed with the influx of Ca2+ and its induction is controlled by the depolarization of the nerve terminal. After the release of neurotransmitter at the synaptic cleft, the membrane of the vesicle will be recycled with a process of endocytosis (Hyman et al. 2009). After the exocytosis, the neurotransmitter starts to diffuse across the synaptic cleft and targets the post-synaptic neuron and its receptors which are localized on the membrane. The binding of the neurotransmitter to the postsynaptic membrane, will cause both biochemical and electrical alterations. Specifically, an excitatory signal will depolarize the membrane and thus a positive charge will pass inside the cell. This depolarization is caused by the opening of sodium channels located on the post-synaptic membrane, which permits the influx of sodium ions across the membrane. On the other hand, an inhibitory signal will hyperpolarize the cell, and thus a positive charge will flow with a direction outside of the cell. This hyperpolarization is induced by an inhibitory postsynaptic potential (IPSP) which cause the influx of chloride ions, which make the membrane potential more negative and the propagation of the action potential significantly more difficult (Hyman et al. 2009). When a neurotransmitter finishes its function, the next step is to be removed from the synaptic cleft. When the local neurotransmitter concentration falls, the neurotransmitter unbounds from the post-synaptic receptor. After this, the neurotransmitter can be either degraded by specific enzymes, or reuptaken by high affinity receptors. The latter corresponds to the most common way of neurotransmitter removal, and includes the reincorporation of the neurotransmitter into the pre-synaptic terminal by endocytosis. This permits the neurotransmitter to be recycled inside the cell. The remaining percentage of neurotransmitters, follows the other path of removal which corresponds to the enzymatic degradation. A characteristic enzyme is acetylcholinesterase (AChE) which degrades the neutrotransmitter acetylcholine into acetate and choline. Another examples of such enzymes include catechol-o-methyltransferase (COMT) and monoamine oxidase (MAO) (Naik 2015). 5) Describe with examples the major mechanisms of action of the different types of neurotransmitter and hormone receptors. In 1907, the physiologist Langley, introduced the aspect of receptor molecules, in order to explain specific properties of molecules on muscle and nerve cells. The neurotransmitter receptors are proteins located in the post-synaptic plasma membrane and contain an extracellular site, specific for the binding of a neurotransmitter. The neurotransmitters, have two distinct families of receptors. The first one, the ligand-gated ion channels or ionotropic receptors, combine the properties of ion channels by having also a neurotransmitter binding domain on their outer part of the membrane. The other family of receptors, are the metabotropic receptors, because the movement of ions depends on certain metabolic steps. The important difference of these channels with the ionotropic channels, is that they dont have an ion channel in their structure, in contrast they have a domain which affects the channels through activation of G proteins, and these receptors G protein coupled receptors (Purves et al. 2001). G protein coupled receptors (GPCRs) are the largest family of membrane protein signaling molecules. The activation of these proteins can be achieved by various ligands, thus modulating the activity of a diverse set of signaling pathways (Kobilka 2007). Nowadays, it is estimated that the human organism contains approximately 800 unique GPCRs, and the 460 of them are assumed to be olfactory receptors (Fredriksson et al. 2003). Their main characteristic is that they contain seven transmembrane-spanning segments, which coordinate the position of the proteins N-terminus at the extracellular space and C-terminus at the intracellular space. Studies in neuromuscular synapse, have demonstrated in detail the neurotransmission mechanism. The binding of the acetylcholine to the postsynaptic receptors, leads to the opening of ion channels. Specifically, the binding of two Ach to a receptor, causes an influx of sodium for milliseconds. In real situations, when an action potential reaches a presynaptic neuron, millions of ACh molecules are secreted into the synaptic cleft. As a result, a high number of AChs will bind to numerous receptors, located on the postsynaptic membrane. The opening of these channels will cause the membrane to depolarize, and the opening of voltage-gated sodium and potassium channels (Purves et al. 2001). When the postsynaptic membrane potential becomes more negative even from the resting potential, the end plate current increases, and decreases when the membrane potential is more positive. At very positive potential, there is a reverse polarity which cause the current to convert form an inward to an outward one (Purves et al. 2001). The other category that we will discuss, the hormones, are produced most of the times by specific cells, and initiate a reaction in certain cell types. Only the cells that have hormone receptors, can be used as hormone target cells. These receptors, recognize certain hormones according to their chemical structure. The classes of these receptors are two, the membrane bound receptors, which are transmembrane proteins and the second category the intracellularly localized receptors which are intracellular receptors (Boon 2009). The membrane bound receptors have an extracellular domain which is linked with an intracellular one. The binding of a hormone are following the rules of noncovalent interactions. In general, signaling molecules for example adrenaline, binds to their receptors with a very high affinity, even higher than the one observed between an enzyme and a substrate. After the binding and the recognition of adrenaline by the receptor, this signal is converted into an intracellular signal, which targets the nuclear compartment. According to the type of the receptors which will bind, adrenaline can cause inhibition of insulin secretion, glycogenolysis and glycolysis (Boon 2009). Furthermore, the hormone insulin, uses for signal transduction a set of tyrosine kinases receptors. The receptors that have tyrosine kinase (TK) activity (RTKs), contain a specific domain for binding ligand molecules located on the extracellular side. Inside the lipid bilayer there is a single alpha-helical element, and inside the cytosol another part that harbors a TK domain. When the RTKs are not bound with the ligand molecule, most of them are in their monomeric state. The only exception of this paradigm is the insulin receptor and in general its family members. When extracellular stimulus is absent, in our case insulin, the kinase domain of the receptors remains in its inactive, auto inhibited state. In this phase, the receptors either have very low kinase activity, or they havent at all. After the binding of insulin on the receptor, the consequent transformational changes that lead to the activation of the TK domain. The activation process of TK includes a trans-autosphorylation of tyrosine residues at segments inside and outside of the TK domain. Then, the phosphorylated P-Tyr which is formed at the site of receptor, becomes a docking region for proteins that harbor phosphorylated tyrosine specific domains. Such proteins are SH2, phosphotyrosine-binding (PTB) and C2 .This signaling eventually leads to an increase of the number of glucose transporter 4 in the outer membrane of specific cells, and thus the increased reuptake of glucose from the blood (Boon 2009).

Macbeth tragic hero Essay -- essays research papers

Tragic Hero or Villain?   Ã‚  Ã‚  Ã‚  Ã‚  MacBeth the play is considered a tragedy and every tragedy needs a tragic hero. There are many factors that caused the degeneration of Macbeth. Macbeth is not a villlian in this story he is a tragic hero. The major factor that started the downfall was the prophecy by the witches in Act 1, Scene 3.   Ã‚  Ã‚  Ã‚  Ã‚  The witches were praising Macbeth. The first witch said, â€Å"All hail, Macbeth! Hail to thee, Thane of Glamis!† The second witch said, â€Å" All hail, Macbeth! Hail to thee, Thane of Cawder!† The third witch said, â€Å"All hail, Macbeth! That shalt be King hereafter!† When Macbeth and Banquo are leaving the witches Banquo is told that he won’t be King but his son’s will be.   Ã‚  Ã‚  Ã‚  Ã‚  In the middle of Act 1 scene 3, Ross tells Macbeth that the Thane of Cawdor is being executed and he will be taking his place. Now Macbeth believes the prophecy told by the witches. He hasn’t quite figured out how he will become King. One of the things that could have also contributed to Macbeth’s downfall is that he is too vulnerable and he believes everything that he hears. The witches corrupt Macbeth’s character and make him power hungry.   Ã‚  Ã‚  Ã‚  Ã‚  In Act 1, Scene 5 Macbeth wrote a letter to Lady Macbeth. Lady Macbeth has a crazy idea; the King is staying in their castle, giving Macbeth a chance to kill the King and become King. Lady Macbeth corrupts Macbeth even more by putting ideas...

The Radio: Past and Present :: Expository Essays Research Papers

The Radio: Past and Present â€Å"He shoots!!! He scores!!!† these are famous words that Foster Hewitt made famous broadcasting a hockey game on the radio (â€Å"The Early Years†). It was words like these that the public became used to because there was no television. The radio served as the first medium to hear things live as they happened. This gave sport fans the opportunity to sit down and tune into a game anytime they like. The radio started off big and then took a dramatic fall due to the introduction of the television. However, radio found new ways to attract the public. Radio broadcasting was introduced to the public in the early 1920s (Potter 226). There was only one type of broadcast protocol in the 1920’s and 30’s being AM radio(The Early Years). In 1921 there were only five AM radio stations, and only about 1% of all households in this country had a receiver (Potter 226). A receiver was basically another name for a radio because at this time radios were very expensive and there were not enough radio stations to make the system work. However, in 1923 there were over 500 stations to pop up which in turn led to increased sales of receivers to the general public (Potter 226). With the popping up of more radio stations the more receivers were being bought which meant that many people in the public were tuning into these various radio stations for information and entertainment. Radio was on the rise and it seemed that there was nothing slowing it down. Radio was at the top of its game during the 1930’s and 1940’s (Potter 226). In 1930 50% of all households had at least one radio, and by 1947 this had increased to 93% (Potter 226). Bye 1936, there was an average of one receiver per household, and in ten years, this had doubled (Potter 226). Sports fans loved the radio because not only could they hear live broadcast but if they missed the game they could get stats all day long. There was only one catch to sports fans listening to games on the radio. Some radio stations did not have enough money to broadcast the games live so they would have a telegraph operator transmit information back to the studio where sounds such as crowd noise, the crack of the bat, and other sounds of that nature were being generated while the game was being played elsewhere (â€Å"Going, Going, Gone!)).

Assimilation or Retaining Ethnic Identity

Assimilation or Retaining Ethnic Identity America was founded by a group of diverse immigrants. All immigrants are coming from different parts of the world such as Asia, Europe, Africa and Mexico and so on. Therefore, each person has his or her own culture, religion and beliefs. Most of the people who are immigrants are non-English speaking and face struggles and numerous challenges to assimilate into American society. Millions of people have been discriminated due to skin color, religions, and beliefs, so it means that people face struggles with assimilation and acculturation.One sure thing is people must understand others cultures when they fall in love with different races, or when they go to school at different countries. However, most of the people are not assimilating for their religion, and they are proud of being what they are. Love is blind. Love is the result of appreciating another’s goodness. So it is wonderful when people fall in love with each other. Love comes f rom emotion, so nobody can limit that one has to fall in love within the same race, especially in the United States where many different races are living together in the same land.That is why it is not an odd thing that white men fall in love with Asian girls or black men fall in love with white girls. But if one falls in love with someone from another race he or she will have to learn and understand his or her culture to build a long term relationship. On December 25th 2005, Junot Diaz published in the New Yorker about â€Å"How to Date a Brown girl, Black girl, White girl or Halfie†. Many people like to read this, and most of the readers commented that it provided really useful tips for the first date with different race girls.Before dating, the speaker Junot Diaz gives advice to the readers: â€Å"Clear the government cheese from the refrigerator†. Moreover, the speaker said â€Å"If she’s a white girl you know you’ll at least get a hand job. † If a man dated the white girl, he could involve sexual activities. He needs to find out what she wants to do after dinner and spends the rest of evening as she likes. According to the Junot Diaz â€Å"If she’s a halfie don’t be surprised that her mother is white. † The girl’s mother will be white or black or Asian, but he shouldn’t show the emotions of shocked and should say â€Å"Hi† to her mother friendly and smoothly.If he doesn’t prepare well to find what she likes or what her culture, he might get broken-heart. Moreover, he will not get a happy relationship. Some people may argue that a good relationship is only based on the personality instead of his or her culture and history, and they don’t need to assimilate others. For example, a white guy’s date with Asian girl may involve sexual activities for the first date. As a result, she may be think he is a ridiculous and rude person, and she won’t meet again bec ause Asian girl hardly ever involve sexual activities before she gets married.Assimilation and acculturation are needed in some situations. According to the Migration World Magazine â€Å"Non-English speaking immigrants grew quickly in numbers†. Most of the immigrants from Southern, and Eastern Europe, Asia and Africa don’t know the English language well. They are struggling with learning English because it takes them a little bit long to speak frequently. In Latino Issue conservative blog, Josue Sierra discussed about getting good English speaking skills is essential for immigrants in education, jobs opportunities, and preventing crime.The speaker says â€Å"If immigrants don’t speak English, chances are they won’t get very far from a low-level laborer positions†. Some immigrants are already graduated and have a higher education in their country, but they only get lower job positions in the United States because they can’t speak English wel l. The speaker also mentions â€Å"An immigrant who has learned English can also look forward to better paying work in their home country†. It means that the immigrants who want to go back home have a benefit by learning English. They can get a better salary than any other in their home country by knowing English well.Some students find difficulties in college because teaching styles are different from their home town and self-study is essential for all students in the United States. For example, Burma which is situated in South East Asia, students are not allowed to argue with the teachers’ ideas. Arguing with teachers is rude and asking questions means students don’t understand the lessons. Moreover, teachers assume asking questions to them means they are not good at teaching, and it insults them. So most of the children are afraid to ask question even they don’t understand. These habits are hard to vanish when they are studying in the United States.Tha t’s why most Asian students are quiet in the class. Moreover, they have to study detail in text books and are not allowed to use their own idea. Next, â€Å"An immigrant that doesn’t speak English will be more hesitant to contact authorities when they are victimized, out of fear of not being understood†. Some of the international high school students have been bullied by English speakers. But they dare not to talk about it to their parents or teachers because they are afraid they can’t explain well. Sometimes, some non-English speaking girls get robbed, but they don’t dare talk to the police.Above these reasons, it is better for immigrants to forget their own origins and try to assimilate the new language. Most immigrants can assimilate living style, wearing style and some cultures in a short time, but they hard to try to assimilate another religion. In the United States, Christian is 78. 4% including Protestant and Catholic; other religions are 4. 7% such as Jewish (1. 7%), Buddhist (0. 7 %), Muslim (0. 6 %), Hindu (0. 4 %), Unaffiliated (16. 1%), Humanism (0. 8%) according to U. S Religious Landscape Survey. A Muslim guy could marry with the Christian girl, even though; the girl or the guy hard to change their religion status.Most of the children who were born to two different religions parents become Humanism. The United States is a democratic country and has freedom of religion and beliefs without government influence or interference. Even though, the country still has problems related to the religious beliefs. For example, in the abortion case, some Catholics don’t agree to destroy the pro-life as â€Å"Don’t kill Jesus’s children† because they assume that people is created by Jesus. For humanism and unaffiliated, they may think this abortion cases are the human right to destroy or not. People dare to die for their religions or their beliefs.So many religion wars have occurred in the world. An other example of religious attack happened on September 11 in New York. Many people’s life lost and the rest of the families felt pain and suffer about this attack. Actually â€Å"Religion is not a way to pigeonhole someone,† Professor of Religion Bruce Lawrence said. â€Å"You can be very Muslim, but also be very American because you appreciate the freedom and opportunity of the country. Loyalty to one's own background is an important part of being American. † Conflict over Muslim immigrants occurs not only in the United States but also in Europe.For example, in France, Muslims girls are banned by wearing chadors (head scarves) by French president. Moreover, in German schools, Muslims girls are asking to take the class of physical education class such as swimming or gym. According to Marion Berning, director of the Rixdorfer primary school in Berlin, Germany, â€Å"We have Muslim girls who say they don't want to swim with the boys. It's obvious the parents exe rt pressure on them, but [the parents] have to accept that coeducation is part of German schools. † These kind of small conflicts lead to ethnic disunity and hostile communities in Europe.In contrast to the European conception, assimilation in the United States â€Å"has always been much more flexible and accommodating and, consequently, much more effective in achieving its purpose,† according to Peter D. Salins, author of Assimilation, American Style. Different immigrants have different ideas of assimilation into American culture. People may get many new experiences and new ideas by assimilating, especially building good relationships and friendships. However, assimilating also has a drawback such as losing one’s own culture and traditions.So immigrants should decide themselves what American cultures support them to have a better life if they assimilate. If they can have a better life due to assimilating into other cultures, they should go for it. Simultaneously , they should keep some value about their own cultures to say what they are.

Philosophy Of Nursing Essay

AbstractA treat philosophical system explains what c are for is and wherefore take fors make the way that they do. A ism of treat is usu each(prenominal)y created by an some wizard checks for manipulation in their daily institutionalize. Nurses use their in-person school of thought to explain what he or she confides palm for is, the role of treat in the healthcare field and how the nurse interacts with the persevering (McEwen & Wills, 2014). A Nurses ism of treat go off guide him or her in practice each day. Before peerless can explore their admit personal nursing philosophy they must come across how nursing theories and philosophies directly affect each. The philosophy of nursing has been defined as the body of work of problems that are ultimate, abstract and general (McEwen & Wills, 2014). These problems are implicated with the nature of world, association, morality, reason and merciful purpose.Philosophy tries to discover knowledge and legality a nd attempts to content to identify what is valuable and of the essence(p)( McEwen & Wills, 2014, p. 25). Philosophys or so grassroots level, hypothesis, has been described as a regular explanation of an event in which constructs and concepts are identified and relationships are proposed and predictions made ( McEwen & Wills, 2014, p. 25). With that world said it is easy to see how a nurses philosophy can determine what compositors case of model or theory he or she uses to guide the care he or she put ups. middling as nursing theory can help to break in a nurses personal philosophy, it is as classic to acknowledge that nursing theories and philosophies both submit a way for a nurse to approach daily practice and case-by-case patients.Personal PhilosophyMy personal philosophy of nursing is non strandd on a single theory save is a melting pot of legion(predicate) theories that has evovoled as my care has evolved over the years. My undivided philosophy of nursing ha s resulted from cosmos the return of an underserved community and seeing first manus how a healthcare providers undivided bias can consider a negative answer on patients outcome. nurse is considered the art of caring and is translated into existence by doing what is right, what is good and ultimately in the best of the patient. I rely that nursing care should be trans ethnic as well as culturally caring. Just as Florence Nightingale investigated what could be make to reference the connection between poverty, distemper and early death during the Crimean war, I believe nursing today should focus on the identification of poverty and discrimination as important contextual factors for an understanding of mixer vulnerability to disease . I believe that cultural qualification should be the ride force behind care and that nursing must seek to address health disparities and risk reductions in doing so.Asnurses as we tend to focus on patient education, preventives, treatments an d diagnoses but forget about the valet de chambre rights aspect and dignity of those who may be social outcasts or of inferior status. It is my philosophy that in order to provide culturally able care to the underserved and disenfranchised one has to cast an understanding of there throw value system and biases. The health packaging model of Nola Pender is deep rooted in my philosophy because I believe as her health promotion model states, valet de chambre have the potential to change and bring in new behaviors volitioningly to win self-selected goals or outcomes. I believe that we all go through unalike stages when seek to make health related changes and it is that interventionwhich is preformed at the right stage that leave behind have the maximum impact in ensuring that the behavioral change will execute a lasting one.This weeks readings have influenced my positioning points by helping me to explore the various nursing theories and providing a framework for which to base my own personal nursing philosophy on. The readings have as well as help me to get a line that I had already established my own personal philosophy based on my own personal values and nonrecreational growth as well as patient encounters, fundamental interactions and knowledge but had not thought of it in abrader sense. philosophic fixationsLeiningers cultural care theory of diversity and universality is based on a belief that people from different cultures can inform and are unfastened of manoeuvre pros so that they may regain the good-hearted of care they desire or need from others. A major concept of this theory is cultural sufficient nursing care uses culturally-based care and health knowledge that is sensitive, creative and meaningful, in a shipway to meet the general and needs of the individual or group.An example of this is when my Hispanic patientasked me about the use of herbaceous plantal supplements to address their medical illnesses. In an effort to provi de care that is culturally competent I take the time to research the herb which the patient wishes to use to see if it will have a negative interaction on the electropositive treatment and if not, not only will I deliver the patient to use them, but I encourage its use as well, while reinforcing to the patient the importance of inveterate to use what I have prescribed also.Another example of culturally competent care use in my practice is with flu vaccinums, I have found in my practice that a draw poker of african americans decline the flu vaccinum for fear of postvaccine illness. I respect the patients right to autonomy, but also educate them on the risk and benefits of the vaccine with hopes that at a subsequent realize they might change their mind. Philosophy and noesis DevelopmentKnowledge development is derived from philosophy and I implement this in practice by providing culturally competent care based on Leiningers cultural care theory of diversity and universality. L eingers theory states that people from different cultures can inform and are capable of guiding professionals so that they may receive the kind of care they desire or need(Tomey & Alligood, 2006). This is wherefore I actively involve the patient in his or her care. favorableness and Post-positivismPositivism supports mechanistic, and reductionist principles, where the obscure is best soundless in terms of basic components (McEwen & Wills, 2014). Post-positivism accepts the subject field nature of inquiry while lighten supporting rigor and objective learning through quantitative research mode and is concerned with explanation and prediction of complex phenomenon, and recognized contextual variables (McEwen & Wills, 2014). Positivism is concerned with the positive application of knowledge to support in human progress. In Nursing Positivism can be utilise to guide care.ConclusionThis paper has condition me the opportunity to recognize that I have always had a philosophy of nu rsing. through self exploration this paper has given over me an opportunity to put into words how super I regard care being provided in a culturally competent manor, because it is by way of cultural competency that we can reach our truly most vulnerable population.ReferencesFlaskerud, J.
