Aspects of Materiality A Continuing Education Report...
Introduction The concept of materiality provides a topic for continuing educational discussion that many firms across the country find essential to the development of their audit staff. Measuring and using materiality to obtain desired results during an audit becomes the responsibility of the staff member of a CPA firm. Partners and managers of a firm typically allow the staff member to use his/her judgment when applying this concept during the fieldwork of an audit. The overall success of an audit relies at least in part on the materiality concept; therefore, staff membersââ¬â¢ continuing education on the concept becomes important and necessary. This report will define the term materiality, determine how to measure materiality, andâ⬠¦show more contentâ⬠¦The article discusses that in 1976 the U.S. Supreme Court ruled in one case that omitted financial statement information altering a reasonable investorââ¬â¢s decision proves the material nature of the information. The article c ontinues by describing that lower courts earlier ruled that all financial information whether material or not must have full disclosure in a companyââ¬â¢s financial statements. The rejection of the lower courtsââ¬â¢ ruling by the U.S. Supreme Court gives the investor the ability to focus on the aspects of the financial statements that are most important by allowing the elimination of minute details (Sauer 2007, 317-357). In essence, this ruling allows for the elimination of financial information below the determined materiality threshold unless otherwise required by the ruling of a regulatory body.

Materiality incorporates professional judgment in practice; however, factual information and the consideration of the needs of the users of financial statements provide a guideline for measurement.

Gross Domestic Product ( Gdp ) - 1695 Words
Gross Domestic Product (GDP) is a description of a nationââ¬â¢s production levels for a period of time, as well as a measurement of economic viability. It is calculated by adding the consumption, investments, governmental outlays, and net exports of a nation in either one year or a quarter. The different components of GDP are at differing levels in each nation. China and Germany, for example, have substantial net exports, and Singapore comparatively relies much more on government outlays to grow its economy. Although the latter uses more governmental outlays than most nations, all nations to some degree make attempts to alleviate economic downturns, as well as to maximize upward movement. Though there must be concern for issues such as the notorious crowding out effect, government activity is often the catalyst to dramatic changes in the economy. The previous example of China as an exporter is true, however it must be noted that it too relies heavily on government expenditures to create a stable economy that has the financial infrastructure to grow. As a matter of fact, all the Economic Tiger nations had to use government planning to change their course from being impoverished nations, to being financial hubs with much room for opportunity in the work force.

Demand and Supply of Iron Ore in Australia- myassignmenthelp
Question: Discuss about theDemand and Supply of Iron Ore in Australia. Answer: Today, iron is one of the most important resources in the world. Fundamentally, this is because the mineral is used in many industries as a raw material. Mainly, it is used in manufacturing industries throughout Australia and the rest of the world. Today, the metal is a major export product from the country. For this reason, any changes in its supply or demand significantly affect the performance of other industries in the economy. Over the recent past, the price of the metal has been low. However, according to an article in the Business Insider, its demand, and hence the price of the metal is expected to rise. In the article CBA says demand for Australian iron ore and coking coal will continue to increase the demand for the product is expected to rise and meet its supply. It is imperative to note that the article may be useful to various stakeholders. For instance, the article may attract the interest of manufacturing companies who use iron as a raw material in their production. In the same way, mining corporations may find the information contained in the article as useful. According to the news, the production of steel in the country is expected to rise in the near future. Consequently, this implies that the demand for iron ore is also expected to rise substantially since it is a main ingredient in the production of steel. In addition, the Australian government is also a key stakeholder in the mining industry. For this reason, government mining agents may take keen interest in the information provided in the article. Fundamentally, the information provided in the article can be explained in terms of economic concepts and theory. According to economic theory the demand and supply of a product influences its price. The law of demand postulates that a rise in the price of a good leads to a decline in its demand. On the other hand, the law of supply proposes that a rise in the price of a product brings about an increase in the quantity supplied of that product. However, some goods such as iron have a low price elasticity of supply (Khan, n.d.). For that reason, a significant increase in the price of iron brings about a less than proportionate increase in the quantity of iron ore supplied. From the article, the reader notes that the demand for iron ore in the country is expected to rise in the near future. More precisely, the author predicts that Australian iron ore exports to China will rise substantially (Pakiam, 2017). Notably, exports to China account for approximately 80 percent of the countrys iron ore export production (Business Insider, 2017). In addition, the demand for Australias iron ore is expected to increase again this year (Monfort, 2017). Furthermore, the demand from India is also projected to increase over time. Therefore, as economic theory suggests, the increase in quantity demanded for iron and its related products will create an upward pressure on its price, forcing it to rise. Graph illustrating the effects of increasing in demand on price Source: (Khan, n.d.). As noted earlier, iron ore has a relatively low elasticity of supply. Markedly, iron ore is a natural resource. For this reason, the resource is scarce and its extraction and production has to be done sparingly to avoid depletion (Adam, 2009). Holding this view, the mining of the product is done in moderation. In turn, it makes the supply elasticity of iron ore in the country low (Diss, 2016). A low elasticity of supply implies that the increase in price of iron following an increase in the demand for the product will be accompanied by a small increase in its supply. Therefore, a continued increase in the quantity of the resource demanded amidst a substantially inelastic supply would result in significant increases in the price of the good in the near future. Graph illustrating inelastic PES Source: (Khan, n.d.). By and large, the increase in demand of the commodity will be very beneficial for the Australian economy. Today, proceeds from the mining sector are a major source of government revenue in the country. More specifically, an increase in export demand for the product will raise export revenue for the country. Consequently, it will improve the countrys net exports and, thus, improve the nations balance of payment position. In this regard, it is crucial for the Australian government to initiate marketing strategies and policies that will ensure an increase in foreign demand for the countrys iron ore. Indeed, an increase in the level of demand from both local and international firms would increase the level of government revenue in the country. This way, the Australian economy will experience substantial increases in its GDP and, hence, economic growth. All in all, all factors taken into consideration, the demand and supply of iron the country is plays a significant role in the Australian economy. Through the article, the reader notes that the demand for iron ore is expected to rise in the near future. Largely, the rise in demand is expected to originate from economies such as India, China, and other Asian countries. On the other hand, the supply of the commodity is expected to change only by a small proportion. Mainly, this is because the mineral is a scarce resource. For this reason, a surplus demand over an inelastic supply of the commodity may bring about significant increases in the price of the metal. Imperatively, the increase in demanded for the product will be beneficial for the Australian economy. As such, the country will benefit from high net exports, leading to an improvement in the nations foreign account. Internal demand would also raise government revenue substantially. Hence, the government should instigate measures that ensure an increase in demand and supply of the commodity. Reference List Adam, G. (2009). Economic Theory Supply and Demand. [Online] Science 2.0.

Synthesis of Aspirin Essay Example
Synthesis of Aspirin Essay Sypnopsis In this experiment, acetylsalicylic acid was synthesized from the acidification of salicylic acid and acetic anhydride. The objective was to convert a specific amount of salicylic acid into the same amount of aspirin that was high in purity. Furthermore, the other objectives were to enable students to conduct the synthesis of aspirin, reinforce skills or recrystallisation and the technique of melting point determination. The amount of each compound should be the same because there is a 1:1 ratio between them. The purity of the synthesized aspirin was measured by determining its melting point and percent yield. Soluble impurities increase the range over which a compound melts and often decreases its overall melting point temperature1. If the experiment went as expected, a pure sample of aspirin with a high percent yield would have been obtained. The percent yield obtained was 56. 1% and the melting point was 134. 7- 136. 8. Introduction Aspirin (acetylsalicylic acid) is a versatile drug that is consumed in huge quantities worldwide. It is a non-steroidal anti-inflammatory drug (NSAID) with a wide range of physiological effects. The first discovery of aspirin occurred in England, in 1963, believing that the bark of willow trees with a beneficial effect in alleviating distress due to fevers, aches, and pains2. Salicylic acid was later extracted from the willow bark and it proved to be an active ingredient. Salicylic acid was synthesized from basic starting materials by 1860 which was helpful to the medicinal field but there were some problems2. Salicylic acid turned out to be irritating to the membranes of the throat, mouth, and stomach.

In 1893, a effective synthesis of acetylsalicylic acid was created, patented in 1899, commercialized under the trade name of ââ¬Ëaspirinââ¬â¢ by the Bayer Company in Germany3. The name ââ¬Ëaspirinââ¬â¢ was invented by the chemist, Felix Hoffman, who originally synthesized acetylsalicylic acid for Bayer3. At very low doses, aspirin is used to treat and prevent heart attacks and blood clots. At higher doses, it is used as an analgesic to reduce pain and as an antipyretic to reduce fever. At very high doses, it is an effective anti-inflammatory agent used to treat rheumatic fever, gout and rheumatoid arthritis. It is also an anticoagulant, it dissolves corns and calluses, and it provokes loss of uric acid (a toxin) but promotes retention of fluids in the kidneys. It kills bacteria and induces peptic ulcers. When ingested, acetylsalicylic acid remains intact in the acidic stomach, but in the basic medium of the upper intestinal tract, it hydrolyzes forming the salicylate and acetate ions. When ingested, acetylsalicylic acid remains intact in the acidic stomach, but in the basic medium of the upper intestinal tract, it hydrolyzes forming the salicylate and acetate ions. The exact mechanisms of its pharmacological actions are still under study. In many plants, salicylate can induce flowering. However, aspirin may cause side effects for example, nausea, vomiting, stomach pain and heartburn. Theory Aspirin is prepared from salicylic acid and acetic anhydride with the help of an acid catalyst. Concentrated sulphuric acid acts as a catalyst. After preparation, the product is purified. This is especially important for chemicals that are used as food additives and pharmaceuticals. The most common method of purifying solid organic compounds is by recrystallization. When an impure solid compound is dissolved in a solvent, it is then allowed to slowly crystallize out as the solution cools. As the compound crystallizes from the solution, the molecules of the other compounds dissolved in solution are excluded from the growing crystal lattice, giving a pure solid. Crystallization of a solid is different from a precipitation of a solid. In crystallization, there is a slow, selective formation of the crystal framework resulting in a pure compound. In precipitation, there is a rapid formation of a solid from a solution that usually produces an formless solid containing many trapped impurities within the solids crystal framework. For this reason, experimental procedures that produce a solid product by precipitation always include a final recrystallization step to give the pure compound. Figure: The esterification of salicylic acid by acetic anhydride5. The -OH group of salicylic acid that reacts with acetic anhydride to form an ester-like product. The carboxylic acid group of salicylic acid remains unchanged. Acetic anhydride is used because it is cheap and forms a by-product, acetic acid. Acetic acid is non corrosive and can be recovered to produce more acetic anhydride. Procedure 2. 4g of salicylic acid was weighed and poured into a 100ml conical flask. The actual weight was then recorded. In the fume hood, 6ml of acetic anhydride was added to the salicylic acid in the flask. To this mixture, 3 to 4 drops of sulphuric acid was added, swirled to mix and then heated in a water bath for 10-15 minutes to complete the reaction. The mixture was removed from the water bath while it was still hot and then 1ml of distilled water was added from a dropper carefully to decompose the excess acetic anhydride. An additional 40ml of cold water was added and stirred with a stirring rod to induce crystallisation. The crude product was collected by suction filtration and washed with a little cold water. The crude product is relatively impure; hence it was needed to be purified by recrystallisation. A solvent suitable for this recrystallization process would be a mixture of ethanol and water. The crude product was dissolved in approximately 5ml of ethanol in a 100ml conical flask and heated on a hot plate. To the solution, 30ml of hot distilled water was added in. The solution was then warmed till all solid has dissolved. The solution was allowed to cool. A clean, dry watch glass together with a filter paper was weighed and the weight was recorded. The recrystallised product was obtained by suction filtration using the weighed filter paper. The crystals and filter paper was transferred onto the weighed watch glass and dried in to the oven (100à °C) for 15 to 20 minutes. The crystals, filter paper and watch glass are then placed in desiccators for 5 to 10 minutes. The dried crystals, together with the filter paper and watch glass were weighed. The weight was recorded and the weight of dried, recrystallised aspirin was calculated. The expected yield of aspirin was calculated from the amount of salicylic acid used. The percentage yield of dried, recrystallised aspirin was also calculated. The melting point of aspirin was determined. Results Mass of salicylic acid Mass of filter paper and watch glass Mass of dried, recrystallised aspirin, filter paper and watch glass Mass of dried, recrystallised aspirinMass of dried, recrystallized aspirin, filter paper and watch glass Mass of filter paper and watch glass Percent yield Number of moles of salicylic acid used (mol wt of salicylic acid = 138) Expected number of moles of aspirin Expected mass of aspirin Percent yield Melting point Temperature Range134. 7 ââ¬â 136. 8 Appearance The crystals are white and shiny, shaped needle-like. The crystals resemble glass wool. Discussion The results and calculations shows how much acetylsalicylic acid was synthesized compared to how much salicylic acid was used. Since there is a 1:1 ratio between the two, then the amount of salicylic acid used should be equal to the amount of acetylsalicylic acid recovered at the end of the experiment. As the result shows, this is not the case, for 1. 83g of acetylsalicylic acid was harvested when 2. 40g of salicylic acid was used. This could have some effect on the purity; for the melting point of the harvested acetylsalicylic acid which is 134. 7 ââ¬â 136. 8 was not very close to the theoretical melting point. The percentage yield is only 56. 1%. Since the final product was determined not to be very pure, it is highly likely that less than 1. 83g of the product was acetylsalicylic acid. Further analysis of the product will have to be done to determine exactly how pure the product actually was. There were several problems that could have contributed to the low purity or mediocre percent yield. When dissolving the initial amount of salicylic acid in the solution of acetic anhydride and concentrated sulphuric acid, it did not completely dissolve into the solution, even when it was heated. There could also be loss of product on the filter paper. Some crystals would be stuck onto the filter paper and this might have affected the mass of the crystals. The sample may not have been completely dried out before weighing. This could have a slight impact on the results of the overall yield of aspirin because it was possible that not all of the salicylic acid was synthesized. To determine if this affected the synthesis of aspirin at all, the experiment should have been ran a second time to see if the same thing occurred. Conclusion The experiment did not go completely as expected. The reaction yielded only 56. 1% of its expected product. The purity of the aspirin was not very high, because there might be impurities in the acid used. Reference 1. Henry, Dr. Geneive. 2004. Susquehanna University.

Behavior essays
Behavior essays One of the problems with strict behavioral theory is that it very much ignores the human variable. When we reduce things strictly to stimulus and response, we can easily forget that there are human feelings, thoughts, and cognitions that are involved in the expression of a behavior as well. In the case of Roger a behaviorist will take everything at face value. If Roger comes in and says he is having trouble studying, it is very likely that the behaviorist will agree with him based on the observable evidence and come up with a reinforcement contingency of some sort to correct his problem. However, the behaviorist is not likely to explore Rogers motivations, interests, or his desires in life. The true cause of the behavioral problem may have to do with thoughts, feelings, or a persons concept of themselves. Behaviorism is ill suited to dealing with these highly abstract concepts. This means that while the behaviorist may address the problem and possibly even find a way to get Roger studying and into business school, he most likely will not be able to address the issue of whether or not Roger should be in business at all; or if indeed he should pursue his music interests. Likewise, behaviorism will be of little help in assisting Roger in his problems with his family, which a psychoanalytically oriented or cognitive therapist would most likely feel are very relevant in his situation. For example, there is a possibility that Roger could be much happier as a musician than as a business professional, and that deep down Roger knows this and that is why he is having difficulty studying. The conflict he is experiencing could be coming from the pressure of his parents who tell him (directly or indirectly) that he should be in the business field, that music is not valued by his father, and that his brother is a failure so Roger must make up for him and make his parents proud. ...

Donââ¬â¢t rely on spellcheck If youââ¬â¢ve ended your email with ââ¬Ëkind retardsââ¬â¢ instead of ââ¬Ëkind regardsââ¬â¢, spellcheck will think thatââ¬â¢s just fine and dandy. Donââ¬â¢t trust it. Make sure you read every word, and if youââ¬â¢re at all unsure about whether you have the right word, look it up. Itââ¬â¢s handy to keep a good online dictionary, such as Collins (our favourite) or Oxford, in your bookmarks bar. 3. Suspect the usual suspects Watch out for these ten most missed mistakes, such as affect and effect and compliment and complement. Print out the list and keep it handy for when youââ¬â¢re proofreading. 4. Print it out Reading on hard copy is the best way to spot errors. Print your document out, walk away from the distractions of your desk and sit down with just pen and paper. Or, if you donââ¬â¢t have a printer, export it as a PDF. Looking at the same words in a different format helps you spot errors that you hadnââ¬â¢t seen before. 5. Check your facts As well as looking for typos, incorrect or missing words, dodgy punctuation and suspect grammar, give your facts a final check. Are the decimal points in the right place? Have you written millions where you meant billions? Have you spelt the customerââ¬â¢s name right ââ¬â and right every time? 6. Take it line by line When you read, your eye flits all over the place. But to proofread effectively, you need to find a way to make sure you read every word. You also need to see the words in the order they appear rather than the order your brain expects them to. Try using a ruler or blank sheet of paper to cover the rest of the text, forcing your eye to move along one line at a time, and a pen to point at each word. 7. Read it aloud Read it out to yourself. Youââ¬â¢ll trip over the awkward bits in a way that you didnââ¬â¢t when reading, and notice missing or extra words. Better still, get someone else to read it out to you, or use Wordtalk, a free plug-in for Word. 8. Once more, with feeling Read it once for facts, once for language and once more for luck. Pay extra attention to titles, subtitles and headings ââ¬â your eye often skips over these and assumes theyââ¬â¢re fine when theyââ¬â¢re not. Read them backwards to be doubly sure. 9. Get a second opinion Ask someone else to proofread it, too ââ¬â someone eagle eyed and straight talking, who will tell you if your witty turns of phrase leave them puzzled or just plain cold. If you dont trust your own eye and you cant find a suitable colleague, consider employing a professional proofreader for particularly important documents. 10. Practice makes perfect The more you proofread, the sharper your eye will become.

(Intro Psychology) Phobias and Addictions (as related to classical and Essay
(Intro Psychology) Phobias and Addictions (as related to classical and operant conditioning) - Essay Example Both phobia and addiction are contrasting psychological disorders. While phobia causes fear due to certain substance, addiction increases dependency of certain substance. In short, phobias and addictions are two emotional difficulties which learning theorists can account for. Phobias and addictions can be better analyzed with respect to classical and operant conditioning in psychology. The theory of ââ¬Å"operant conditioningâ⬠was formulated by B.F. Skinner in 1930. ââ¬Å"It is based upon the idea that learning is a function of change in overt behavior. Changes in behavior are the result of an individual's response to events (stimuli) that occur in the environmentâ⬠(Operant Conditioning (B.F. Skinner), n. d). On the other hand the theory of classical conditioning was put forward by Pavlov which states that certain responses can be developed with the help of certain stimulus. This paper analyses phobias in relation to theory of classical conditioning and addictions in re lation to operant conditioning. Phobias and theory of classical conditioning ââ¬Å"Several types of learning exist. The most basic form is associative learning, i.e., making a new association between events in the environment. There are two forms of associative learning: classical conditioning and operant conditioningâ⬠(Classical conditioning, 2008). Pavlov explained his theory of classical conditioning with the help of a dogââ¬â¢s response to meat. ... However, the dogââ¬â¢s mouth filled with saliva immediately after hearing the bell. Pavlov argued that the stimulus (Sound of Bell) produced a response (the saliva). In other words, he proved that certain behaviors can be conditioned with the help of certain stimuli. Phobias can be explained with the help of classical conditioning. For example, suppose a person suffered the attack of a dog once. He can develop the phobia of feeling afraid of dogs from then onwards. It is not necessary that all dogs may attack human. However, the person who suffered the attack of a dog may always watch dogs with fear and concerns because of his previous experience. Addictions and theory of operant conditioning ââ¬Å"Skinner used the term operant to refer to any "active behavior that operates upon the environment to generate consequencesâ⬠(Wagner, 2009). ââ¬Å"When a particular Stimulus-Response (S-R) pattern is reinforced (rewarded), the individual is conditioned to respondâ⬠(Operant Conditioning (B.F. Skinner), n. d). Skinner argued that certain stimulus can reinforce positive or negative behaviors. Consider a parent tries to wake up his son early in the morning at about 4am for studying his lessons. Initially the child may show some reluctance to wake up and study early in the morning. Also consider the child may be very much interested in having a black coffee early in the morning. If the parent provides him the black coffee after waking him up by 4 am for a period of one week continuously, the child may automatically wake up from the next week onwards asking for the coffee. Here the reward, black coffee has strengthened or reinforced the behavior of waking up and studying early in the morning. Addiction can be better understood with

Analyse the way Beatrice and Benedick Essay Example for Free
Analyse the way Beatrice and Benedick Essay The characters Beatrice and Benedick in the William Shakespeare play ââ¬Å"Much Ado About Nothingâ⬠can be described as sparring lovers. At the start of the play, it is difficult for them to converse without becoming involved in a ââ¬Å"merry warâ⬠or a ââ¬Å"skirmish of witâ⬠. This attitude gradually changes as the play progresses. I shall analyse the way in which this attitude changes as Beatrice and Benedick engage in parlance. From Act One, Scene One, Beatrice demonstrates hypocrisy when to Benedick she says ââ¬Å"I wonder that you will still be talking, Signor Benedick, nobody marks youâ⬠. The ironic part of this is that she is actually listening to him. Therefore, as much as she may like to deny it, she is giving the man she ââ¬Å"detestsâ⬠her undivided attention, and is noticing him. Benedick, in a quick flash of wit answers back ââ¬Å"What, my dear Lady Disdain! Are you yet living? â⬠As Benedick asks Beatrice if she is living, it presents the witty assumption that Benedick has not been aware of Beatriceââ¬â¢s presence. A very well-put reply to this from Beatrice is that ââ¬Å"Disdainâ⬠canââ¬â¢t die whilst Benedick is there ââ¬Å"feedingâ⬠it to carry on. This battle of wit which occurs between the both of them illustrates the deep loathing that they appear to have for one another. As we shall discover further on in the play, this seems only to be a guise for the immense passion they have for each other. There is, here, however, a suggestion from Beatrice that both of them have had a relationship before: ââ¬Å"You always end with a jadeââ¬â¢s trick. I know you of oldâ⬠. The aforementioned evidence of a possible relationship provides a reason for the skirmish of wit, and also implies there may still be romantic feelings between the two. In Act Two, Scene One, Beatrice is dancing and having a conversation with a masked Benedick. It is not clear, and remains the decision of the reader whether Beatrice truly knows that she is speaking with Benedick. She goes on to describe him as ââ¬Å"the princeââ¬â¢s jester, a very dull foolâ⬠. As there is a sense of possession ââ¬Å"the princeââ¬â¢s jesterâ⬠, it creates the impression that Beatrice sees Benedick as nothing more than a puppet. When speaking with Claudio, Benedick makes it clear he was shocked by this: ââ¬Å"Lady Beatrice should know me, and not know me: the princeââ¬â¢s fool! Hahâ⬠¦Ã¢â¬ â⬠¦ ââ¬Å"Every word stabsâ⬠. Here, Shakespeare has used a dramatic device, ie: the masqued ball, and the inherent identity confusion to make Benedick believe that Beatrice had all along intended to speak ill of him. It is for this reason that I believe that Beatrice knew full well that she was indeed speaking to Benedick. In Act Two, Scene Three, Benedick is successful tricked into thinking that Beatrice is in love with him. However, this trick has not yet been carried out on Beatrice. In the garden, Beatrice approaches Benedick and announces ââ¬Å"I do spy some marks of love in herâ⬠. This is ironic because there are none. The passion she shows is one of hate for what she is about to say: ââ¬Å"Against my will I am sent to bid you come in to dinnerâ⬠. When asked by Benedick if she ââ¬Å"takes pleasure in the messageâ⬠, she says ââ¬Å"Yea, just so much as you may take upon a knifeââ¬â¢s pointâ⬠(ie: not at all). Benedick has got completely the wrong end of the stick in his soliloquy: ââ¬Å"thereââ¬â¢s a double meaning in thatâ⬠, and thinks that she does not want him to come in, but instead to stay out in the garden with her. Hence, his going inside would not be a pleasurable message for her. However, this is an example of dramatic irony as we know this is not the case at all. Shakespeare points out the truth beneath the characters surface, as well as using language as his tool to juxtapose these feelings, in effect, switching the meaning around so that the connotations are what illuminate the truth. He is also able to use a technique to capture the truth beneath the surface of the characters. Everything that is spoken by the characters seems to have a deeper or double meaning under the words. In Act Four, Scene One, Benedick declares his love for Beatrice. He does this so she will call upon him to right Hero from the terrible injustice that recently occurred at the wedding scene. He asks her if it seems strange that he loves her. This is again an example of dramatic irony, because the audience knows that itââ¬â¢s not strange ââ¬â she knows already that he loves her. Beatrice, usually extremely able to articulate herself is strangely not able to here. The use of commas and colons break up the following speech, as she is overcome by fierce emotions. She is therefore not able to articulate anything but the fact that she feels sorry for her poor cousin who has been wronged. ââ¬Å"It were as possible for me to say, I loved nothing so well as you, but believe me not, and yet I lie not, I confess nothing, nor I deny nothing. â⬠Beatrice, therefore equivocates here being deliberately ambiguous or unclear in order to mislead or withhold information, ie: her love for Benedick. This is particularly emphasised by the long sentence length. Benedickââ¬â¢s immediate rejection at the idea of killing Claudio ââ¬Å"Not for the wide world! â⬠elicits anger, and impatience in Beatrice who doesnââ¬â¢t wish to converse with Benedick any longer. After much deliberation, knowing it will please Beatrice, Benedick agrees to ââ¬Å"useâ⬠his hand ââ¬Å"in some other way than swearing by itâ⬠. In other words, he has agreed to engage Claudio in a duel. Beatriceââ¬â¢s reason for wanting him killed is that ââ¬Å"he is now as valiant as Herculesâ⬠. This allusion to Hercules implies that Claudio has become too boastful, too big for his boots. In conclusion, itââ¬â¢s clear to see how the attitude between the two changes, and the relationship progresses. Shakespeare employs the use of juxtaposition to mask true feelings. The best illustration of this juxtaposition masking is of the relationship between Beatrice and Benedick. Their incessant banter and wit-battles mask the true feelings each has for the other.

OBJECTIVES Corporate Objectives: To give an insight to the ice cr eam industry, the company and the product line. To make an assessment of the interaction between ââ¬ËLordââ¬â¢s Ice-cream Parlourââ¬â¢ and its immediate environment and analyse the impact of various trends upon its survival and long-term success.

To explain and analyse the role of Marketing Research. To have a clear analysis of the various growth strategies for the market opportunity identification. Research was undertaken by gathering descriptive information from the managers, customers and employees in the form of personal interviews. Both quantitative and qualitative analysis has been emphasised. Both primary and secondary data were obtained through informal interviews with the company and questionnaires to customers. Moreover in cases where managers and customers were unwilling or unable to provide information, observational research played a vital role. It must be added that the report though, tried to give an overall view of ââ¬ËLords Ice-cream Parlourââ¬â¢, it focused on London City as their area of study. Primarydata was first collected by taking in depth interviews of the Marketing Executive and Sales person to have a better insight to the marketing aspects of ice cream. Mostly personal interviews were undertaken since flexibility, quality of data that can be collected, speed of data collection and response rate is extremely high and information seems to be more reliable and effective. Only unbiased, relevant and valuable data of related issues were recorded to ensure a critical evaluation of the marketing techniques and strategies used by ââ¬ËLords Ice-cream Parlourââ¬â¢. Problems were faced during the interview, as the managers were reluctant to disclose some of the confidential aspects of the organisation. All the data obtained were not always reliable and hence subject to error. Due to the time constraints I could not complete a comprehensive investigation and there were some areas that were left unexplored. In many occasions managers were hesitant to cooperate in providing honest answers. 8. 1 The Marketing Environment No business is large or powerful enough to create major change in the external environment. These factors are generally uncontrollable, thus market managers are basically adapters rather than agents of change. So it is vital for ââ¬ËLords Ice-cream Parlourââ¬â¢ to take these factors into consideration in every step of their decision -making process and day-to-day activities. THE MARKETING ENVIRONMENt {draw:frame} {draw:frame} {draw:frame} The Task Environment ââ¬ËLords Ice-cream Parlourââ¬â¢s task environment consists of those micro groups in the environment such as suppliers, distributors, customers and competitors.

COMPETITORS: One of the most important forces that always keep an organisation on guard is its competitors. Competitors are organisations that produce similar goods. In the context of ââ¬ËLords Ice-cream Parlourââ¬â¢, Movenpick, Baskin Robbins, Thorntons and Marine Ices are their competitors. But surprisingly, the marketing management of ââ¬ËLords Ice-cream Parlourââ¬â¢ views these local brands as mere participants in the same industry rather than as competitors. The General Environment Economic, technological, socio-cultural, demographic, political and legal, and global forces form the macroeconomic environment that ââ¬ËLords Ice-cream Parlourââ¬â¢ operates in are as follows: ECONOMIC: Economic forces are of concern to businesses involves producing goods and services that people want and pay for, as because the economy is an indicator of the general health and well being of a nation. ââ¬ËLords Ice-cream Parlourââ¬â¢ takes into account various economic factors, preferably the rates of inflation, the exchange rate and level of income.

One of the most pervasive factors in the environment, the impact of technology is seen as the combination of skills and equipmentââ¬â¢s that marketers use in their day-to-day operations. In ââ¬ËLords Ice-cream Parlourââ¬â¢, use of technology can be seen in terms of the automated cone baking machines, chocolate making machines, injected deep freezers, milk processing machines and others. These innovate machines are able to produce ice creams at a faster rate while not undergoing any sacrifice in the level of quality, and thus their warehouse has capacities in five hundred liters.

As a result cash from the construction company flows out to support other SBUs that needs more resources. Star: Star has high market growth rate and high market share. The Marketing Manager of ââ¬ËLordââ¬â¢s Ice-cream Parlourââ¬â¢ identified Construction and Ice-cream as their star businesses. A number of prospective factors can be reckoned to as being responsible for both SBUs performance. Both Construction business and Ice-cream occupy a dominant position in the market. Star businesses usually grow very fast and have high prospects for growth. For example, Ice-cream grew by 3. 1% in the last year (2008), compared to their 5%in (2007). Question Mark: Question Mark has high growth rate, low market share. The identification of the marketing division of ââ¬ËLordââ¬â¢s Ice-cream Parlourââ¬â¢ as its problem child, has characterized this business to have high prospects for growth but which has not yet achieved strong foothold in an expanding but highly competitive market. This inability to generate cash has resulted in poor profit margins and hence its need to be augmented by heavy investment from outside sources. Dog: According to ââ¬ËLordââ¬â¢s Ice-cream Parlourââ¬â¢, no SBU (currently operating) falls under the grid of low market share and low growth rate, that is, the dog. On a concluding note, the long run health of any company depends on having some products that generates cash (and provide acceptable reported profits) and others that use cash to support growth, with no exception to ââ¬ËLordââ¬â¢s Ice-cream Parlourââ¬â¢. Among the indicators of the overall health are the size and vulnerability of the cash cows, the prospects for the stars, the number of problem child, and dogs if many. 10. SWOT Analysis SWOT is the planning exercise used by ââ¬ËLords Ice-cream Parlourââ¬â¢, which provides a framework for identifying internal strengths and weakness and the external opportunities and threats it faces. WEAKNESS: The major weaknesses of ââ¬ËLords Ice-cream Parlourââ¬â¢ comprises of: Incurrence of high-level expenses in the Research and Development (R) sector. High operating and maintenance expenses resulting from the large size of the business. Excessive reliance on foreign suppliers. Entering new related businesses ââ¬â This is also visible through its new items as Ammo milkshake. Widening the product range. Seeking faster market growth. Exploiting new market segments. Changes in demographic factors. Change in consumer taste: This might result if there is an increased awareness among the health conscious people, which may cause a decline in the purchase of ice cream. Increase in foreign competition. Rise in new or substitute products. Changes in Political factors. 10. THE *Target *AUDIENCE (*Marketing*) The kind of market ââ¬ËLords Ice-cream Parlourââ¬â¢ operates in is characterized by the volatility of its general environment, the dynamism of its competitors and most of all the varying and the inconsistency of needs and buying preferences of the consumers market, which are important consideration guiding their day to day operations. Keeping this in mind, ââ¬ËLords Ice-cream Parlourââ¬â¢ has developed sound marketing programs, which starts with identifying the differences that exists within a market, deciding which segments will be selected and developing specific marketing mixes so as to influence intended customers, and overall perception of the brand, ââ¬ËLords Ice-cream Parlourââ¬â¢ . Market Segmentation ââ¬ËLords Ice-cream Parlourââ¬â¢ has designed various marketing mixes according to the different products needs and preferences with regard to the consumer market and has clustered people with similar needs into selected segments. Domestic Market Segmentation For a consumer-oriented company like ââ¬ËLords Ice-cream Parlourââ¬â¢, whose main operations rallies around the domestic market, a lionââ¬â¢s share of its resources is devoted towards serving the domestic consumer segments. After thorough analysis, behaviour and demographic segments have been identified as their prime areas of focus. Demographic Segmentation From the viewpoint of an ice cream manufacturing company, demographic segmentation holds importance in terms of its close relation to customer product needs and purchasing behaviour and the ready measurability of variables such as consumersââ¬â¢ age and life cycle and their income. Age: This is the most important component of demographic segmentation. Over the years, ice creams were considered to as being more of a recreational product, but standing on this new century, the effect of globalization has placed ice cream as more of a regularity in our lives. ââ¬ËLords Ice-cream Parlourââ¬â¢ has divided its markets in segments according to different age groups such as kids, teenagers, and the family range. Different ages of people are influenced by different flavours of ice cream, different presentations of packaging and different product attributes. Kids incline more towards ice creams, which contains animated and colourful packaging, taste of sweet strawberry, fresh mango, pure vanilla, ripples, hazzle nut coating and crispy flakes. Teenagers prefer low calorie ice cream, more daring and wider range of tastes. Families are influenced more by ice creams that fulfil the general appeal and taste of all the members of the family. Income: Income is the key determinant of consumers buying behaviour. It is the most popular demographic variable for market segmentation. For a larger part of the population to buy the product, it is very important to segment the market in different income groups. This is given utmost importance in London where there is wide variation in the average levels of income. ââ¬ËLords Ice-cream Parlourââ¬â¢ has divided the market into three income groups ââ¬â low-income group, mid-income group and high-income groups. Market Targeting After market segmentation, ââ¬ËLords Ice-cream Parlourââ¬â¢ goes for designing, implementing and maintaining marketing mixes intended to meet the needs of the target groups, resulting in mutually satisfying exchanges. Domestic Market Targeting The two general strategies ââ¬ËLords Ice-cream Parlourââ¬â¢ uses for selecting target markets are differentiated and undifferentiated marketing. DIFFERENTIATED: UNDIFFERENTIATED: Undifferentiated target strategies approach the segment as one big market with no individual segments and thus require a single marketing mix. Chocobar and the newly introduced Kulfi are the prime examples related to successful targeting of the mass market. Chocobar priced at ? 3. 4/-, mini chocobar priced at ? 2. and Kulfi priced at ? 1. 6 with sober colour packages enables ââ¬ËLords Ice-cream Parlourââ¬â¢ to go for mass marketing. Market Positioning Positioning refers to developing a specific marketing mix to influence potential customers overall perception of a brand, product line or organization. The marketing manager of ââ¬ËLords Ice-cream Parlourââ¬â¢ assumes a realistic view of how customers think about their offerings in the market. At the same time, the ma nger also knows how he wants target customers to think about its marketing mix. According to him positioning issues are especially important when a competitor in a market appearsto be very similar, with the ice cream industry being a prime example. ââ¬ËLords Ice-cream Parlourââ¬â¢ follows several positioning strategies. Products Attributes Macho ââ¬â Exquisite Chocobar ââ¬â Energetic Shell & Core ââ¬â Metange Lolly ââ¬â Eager Clown ââ¬â Animating Mega ââ¬â Energetic Coffee ââ¬â Refreshing Ripple ââ¬â Praiseworthy Pralin ââ¬â Puissance Cornelli ââ¬â Dual Usage Occasion: Usually consumers perceive ice cream as an integral part of summer. Lords Ice-cream Parlourââ¬â¢ aims at positioning ice creams to as being a winter item along with its regular summer item image. ââ¬ËLords Ice-cream Parlourââ¬â¢ is trying to position its ice cream as a item for all seasons in other parts of the country like that is perceived in London, through different promotional activities. *11. THE* Marketing Mix There are many possible wa ys to satisfy the needs of target customers. A product can have many different features and quality levels. Service levels can be adjusted. The package can be of various sizes, colors or materials. The brand name and warranty can be changed. Various advertising media ââ¬â television, newspapers, magazines, radio, and billboard can be used to attract the potential customers. A companyââ¬â¢s own sales force or other sales specialist can be used. Different prices can be charged. Price discounts may be given and so on. With so many possible variables, is there any way to help organize all these decisions and simplify the selection marketing mix? The answer is ââ¬â The customer is surrounded by the four Pââ¬â¢s. There are additional three Pââ¬â¢s newly invented by the marketer. An important point to note is the customer should be the target of all marketing efforts but it is not the part of the marketing mix. Hence, ââ¬ËLords ice-cream parlourââ¬â¢ follows this concept and places its customers in the centre. Product: for ââ¬ËLords ice-cream parlourââ¬â¢ the Product decisions revolve around developing the right product for the target market and this includes not only the physical unit but also features, brand name, company image, value and many other factors. Apart from maintaining a superior quality through its imported ingredients and bringing regular production consultants from Belgium, Denmark and Holland, the unitsââ¬â¢ separate R department regularly can analyzes new products through its market research to answer questions as: At what price consumers would like to buy the product. Flavours and essence to be used. Consumersââ¬â¢ feedback. Analyze other markets. ââ¬ËLords ice-cream parlourââ¬â¢s Product line includes distinctive ingredients, as some are vanilla flavour with chocolate hazelnut or milk coating, some may have crispy flakes, others include cashew nut. On the other hand, to provide a taste of refreshment there are flavours including coffee, strawberry, mango, with almonds and ripples. Each of these delicacies has positioned itself as a unique brand in consumerââ¬â¢s mind. These eclectic tastes have been able to exceed consumerââ¬â¢s expectations resulting to delightful consumers and thus to the creation of a powerful company image. Apart from that ââ¬ËLords ice-cream parlourââ¬â¢ also can operates through some trolleys for extending its reach to various consumers at different locations as schools, alleys, streets, parks e. . c. Consumers ââ¬â Availability of scratch cards through purchase of certain flavoured ice creams enables consumers to obtain different types of gifts such as iPod, mp3 player can be achieved by them. Also last year (2008) every purchase of Macho had a Kit Kat free. *PEOPLE*: The management of the ice-cream parlour is very particular about the selection of the people. They are hiring only the mot ivated, energetic and passionate people. The parlour has on job training and skill development continuous activity by which employee can be skilled. But from next year every after three months they are going to arrange a training and motivation program for the improvement of their business. *12. MARKETING* Growth Strategies ââ¬ËLords ice-cream parlourââ¬â¢, like any other company, in order to maintain a stable growth rate, focuses on reviewing the existing operations, the evaluations and the creation of the new products by not only manufacturing the highest quality products but also delivering the product by maintaining this high quality. In seeking growth, ââ¬ËLords ice-cream parlourââ¬â¢ considers both its market and its products. It then decides whether to continue what it is doing ââ¬â only do it better ââ¬â or establish new venture. The product/market growth matrix depicts this option for ââ¬ËLords ice-cream parlourââ¬â¢. The matrix is divided into four possible combinations of old and new products with old and new markets. {draw:line} {draw:line} {draw:line} {draw:line} {draw:line} {draw:line} {draw:line} {draw:line} {draw:frame} MARKET PENENTRATION: Here, ââ¬ËLords ice-cream parlourââ¬â¢ tries to sell more of its present products to its present markets by the help of supporting tactics, which might include spending on price, promotion and packaging. For example, ââ¬ËLords ice-cream parlourââ¬â¢ regularly alters its ice cream packaging, and provides occasion oriented price cut. MARKET DEVELOPMENT: ââ¬ËLords ice-cream parlourââ¬â¢s market development strategy is evident by its entry to an entirely new area ââ¬â Marble Arch. In future, ââ¬ËLords ice-cream parlourââ¬â¢ plans to expand in other parts of London and are undergoing business consultancy of possible expansions in Netherlands. PRODUCT DEVELOPMENT: Nothing is more important to a companyââ¬â¢s long-term survival and growth then the successful introduction of new products. By flipping through ââ¬ËLords ice-cream parlourââ¬â¢sbook of achievements, it is evident that one of prime reasons for success has been due to constant introduction of new products. The exquisite Macho, energetic Mega, which hit the markets around two years back, were and are a real feast for ice cream lovers. The very recently introduced Kulfi has once again placed ââ¬ËLords ice-cream parlourââ¬â¢ to as being a peopleââ¬â¢s brand providing a world of great taste, and which deciphers ââ¬ËLords ice-cream parlourââ¬â¢s drive to maintain satisfaction of all segments of the market. Lords ice-cream parlourââ¬â¢ has, for the time being confined itself only to the ice cream business. Any diversification related businesses would be future-wise. The Marketing Budget {draw:frame} Recommendations In spite of ââ¬ËLords ice-cream parlourââ¬â¢s remarkable success certain loopholes in the marketing aspects has been detected. After my research I came up with some possib le steps and solutions that we would like to state below. Competitors are an important component of the task environment. ââ¬ËLords ice-cream parlourââ¬â¢ should pay heed to its potential competitors rather than treating them as mere counterparts. Lords ice-cream parlourââ¬â¢ should involve in backward vertical integration to lower the costs of value creation and lessen its reliance on foreign suppliers. For instance, incidence such as credit crunch may hinder the flow of supplies in the production process when there is excessive dependence on foreign inputs. To enhance the maturity level, ââ¬ËLords ice-cream parlourââ¬â¢ should undertake the task of sponsoring more social events such as concerts, cricket, football and other such tournaments to retain its popularity in the younger market segments. Emphasize should be given on TV commercials, to capture a greater share of the market. A proper customer help line should be developed to mitigate the further needs of the customer.

James Clerk Maxwell essays
James Clerk Maxwell essays James Clerk Maxwell was a British physicist. Maxwell was born in Edinburgh, Scotland on November 13, 1831. He was educated at Edinburgh Academy from 1841 to 1847. He then entered the University of Edinburgh, and went on to study at the University of Cambridge in 1850, graduating with a bachelor's degree in mathematics in 1854. In 1860, he moved to London to become a professor of philosophy and astronomy at King's College. Due to the death of his father in 1865, Maxwell returned to his family in Scotland and devoted himself to research. In 1871 he moved to Cambridge, where he became the first professor of experimental physics and set up the Cavendish Laboratory, which opened in 1874. Maxwells first important contribution to science began in 1849, when he applied himself to examining how human eyes detect color. He proved Youngs theory that the eye has three kinds of receptors sensitive to the primary colors. He invented the trichromatic process. Using red, green, and blue filters, he took the first color photograph in 1861 of a tartan-patterned ribbon. This proved to be the ancestor of all color photography. Maxwell was best known for his work on the connection between light and electromagnetic waves. Electromagnetic waves are traveling waves of energy. Maxwell discovered that light consists of electromagnetic waves and established the kinetic theory of gases. The kinetic theory of gases explains the relationship between the movement of molecules in a gas and the gas's temperature and other properties. Maxwell's improvement of the kinetic theory of gases was inspired by his success in the similar problem of Saturn's rings. He believed that a solid ring would collapse, and that therefore the rings of Saturn must be made up of many small bodies orbiting the planet. This was concluded through photographs taken from the spacecraft ...

Lanthanides Definition in Chemistry
Lanthanides Definition in Chemistry Below the main body of the periodic table are two rows of elements. These are the lanthanides and the actinides. If you look at the atomic numbers of the elements, youll notice they fit in the spaces below scandium and yttrium. The reason they arent (usually) listed there is because this would make the table too wide to print on paper. Each of these rows of elements has characteristic properties. Key Takeaways: What Are the Lanthanides? The lanthanides are the elements in the top of the two rows located below the main body of the periodic table.While there is disagreement over exactly which elements should be included, many chemists state the lanthanides are elements with atomic numbers 58 through 71.Atoms of these elements are characterized by having a partially filled 4f sublevel.These elements have several names, including the lanthanide series and the rare earth elements. The IUPAC preferred name is actually lanthanoids. Lanthanides Definition The lanthanides are generally considered to be elements with atomic numbers 58-71 (lanthanum to lutetium). The lanthanide series is the group of elements in which the 4f sublevel is being filled. All of these elements are metals (specifically, transition metals). They share several common properties. However, there is some dispute over exactly where the lanthanides begin and end. Technically, either lanthanum or lutetium is a d-block element rather than f-block element. Yet, the two elements share characteristics with other elements in the group. Nomenclature The lanthanides are indicated by the chemical symbol Ln when discussing general lanthanide chemistry. The group of elements actually goes by any of several names: lanthanides, lanthanide series, rare earth metals, rare earth elements, common earth elements, inner transition metals, and lanthanoids. The IUPAC formally prefers the use of the term lanthanoids because the suffix -ide has a specific meaning in chemistry. However, the group acknowledges the term lanthanide predates this decision, so it is generally accepted. Lanthanide Elements The lanthanides are: Lanthanum, atomic number 58Cerium, atomic number 58Praseodymium, atomic number 60Neodymium, atomic number 61Samarium, atomic number 62Europium, atomic number 63Gadolinium, atomic number 64Terbium, atomic number 65Dysprosium, atomic number 66Holmium, atomic number 67Erbium, atomic number 68Thulium, atomic number 69Ytterbium, atomic number 70Lutetium, atomic number 71 General Properties All of the lanthanides are shiny, silver-colored transition metals. Like other transition metals, they form colored solutions, however, lanthanide solutions tend to be pale in color. The lanthanides tend to be soft metals that can be cut with a knife. While the atoms can exhibit any of several oxidation states, the 3 state is most common. The metals are generally quite reactive and form an oxide coating upon exposure to air. Lanthanum, cerium, praseodymium, neodymium, and europium are so reactive they are stored in mineral oil. However, gadolinium and lutetium only slowly tarnish in air. Most lanthanides and their alloys quickly dissolve in acid, ignite in air around 150-200 à °C, and react with halogens, sulfur, hydrogen, carbon, or nitrogen upon heating. Elements of the lanthanide series also display a phenomenon called lanthanide contraction. In lanthanide contraction, the 5s and 5p orbitals penetrate into the 4f subshell. Because the 4f subshell is not fully shielded from the effects of the positive nuclear charge, the atomic radius of the lanthanide atoms successively decreasing moving across the periodic table from left to right. (Note: This is, in fact, the general trend for atomic radius moving across the periodic table.) Occurrence in Nature Lanthanide minerals tend to contain all elements within the series. However, the vary according to the abundance of each element. The mineral euxenite contains lanthanides in nearly equal proportions. Monazite contains mainly lighter lanthanides, while xenotime contains mostly heavier lanthanides. Sources Cotton, Simon (2006).à Lanthanide and Actinide Chemistry.

Why societies collapse Essay Example | Topics and Well Written Essays - 750 words
Why societies collapse - Essay Example They have happened thousands of years ago and will continue to happen as new empires and societies rise and fall. There are different and numerous reasons for the demise and the fall of societies and for most of these societies and civilizations, the causes are the same and similar. The usual aspects that cause the collapse and the decline of a certain civilization or empire are economic, environmental, political, social and cultural factors. Some causes take effect immediately and others are gradual. Some reasons and factors for the collapse of a society are certain and others, a mystery. Throughout world history, there are several notable and famous empires and kingdoms that have collapsed after several years of their rise and development politically, economically and socially. The Han Dynasty in China was one of the most influential and the most powerful empires in ancient China. Today, the majority of an ethnic group of people in China are called ââ¬Å"the people of the Han.â⠬ Even though they were greatly powerful and was an immense empire, they collapsed after four hundred years of reign and rule. There were several reasons why this great and grand empire and dynasty declined and eventually collapsed and fell. One of the main reasons for their ruin was the wars and the invasion and attacks by different groups that resulted in the weakening of the empireââ¬â¢s economy. ... ty, in an attempt to make reforms that would effectively reinstate and bring back the success, prosperity and the glory of the empire, made far-reaching modifications and alterations. However, natural disasters struck and resulted in a scarcity of food supply. Rebellions by peasants sprung up and Wang Mang died soon after. Although the Han dynasty was able to recover from the great downfall of the economy, it never regained back its great success and affluence and in 220 AD, formerly collapsed and came to an end. After hundreds of years on the other side of the world, the Roman Empire also experienced its rise and fall. Just like the Han Dynasty, it was one of the greatest empires in history and similarly, there were also a number of different grounds and causes of its fall. One of the said key reasons was the split of the Roman Empire between the West and the East (also known as the Byzantium Empire.) There were also several civil wars that occurred. Some emperors such as Commodus g ave in to immorality and practiced violence, which caused his assassination and this resulted in the beginning of the collapse of the empire. The Roman people ultimately lost their power as barbarian ns in the North frequently invaded and attacked. The Roman army started to become disloyal to the empire. The infrastructures such as bridges and pathways were not maintained, causing trade and communication to stop. Christians were heavily persecuted and people gathered in crowds and cheered on as people died violent deaths. The falling economy caused food supply to run out. With all these troubles and problems, the Roman Empire in time collapsed and fell. The causes and reasons for the fall of both the Han Dynasty in the East and the Roman Empire in Europe ere certain. However, it is not

WORKING WITH AND LEADING PEOPLE Essay Example | Topics and Well Written Essays - 2750 words
WORKING WITH AND LEADING PEOPLE - Essay Example In that case, the retention, selection, as well as the recruitment process is imperative for every firm. In recruiting a new member, there is a need to have a different document, the firm must obey the statutory laws, and go beyond the sequential procedure of selecting (Bell 2012).The human resource department has the mandate to select the right people and prepare a document that details various rules as well as regulations. The management of the restaurant needs to prepare a document detailing various aspects such as the approval of recruitment. The concerned departments who require a new worker then send a draft, which has a description of the position and the necessary education as well as skills that are required. Subsequently, the draft is approved and sent to the HR department. The selection as well as recruitment process commences after the management gives an approval with regard to the request. The approval should have an electronic copy that has the advertisement as well as the copy of the draft. In the document, there is also the description of the position for which the restaurant needs to recruit new trainees. This is imperative for every firm since it cannot change the position after the advertisement of the post. It is also to be understood that the post needs to be approved by the management and should include the responsibility of the new staff (Dessler 2011). After the position description there is the advertising section, which needs to be approved by the director. Through the advertisement, the firm will get the right candidates and can be done using various channels such as the use of print media, open advertisement, or electronic means. The advertisement will also include announcement on the vacancy, the required competencies, and payment among others. The HR department will need to obey the legal procedures of advertisement (Bell 2012). In selecting an applicant, I would
