The UAE Islands

Over the last few decades, the issue of the rightful owner of the three islands in the Gulf region has been a highly contested matter between Iran and the United Arab Emirates. The three islands : Greater Tunbs, Abu Musa, and Lesser Tunbs amounts to lesser than 26 KM2 of scrub and sand. However, the islands’ proximity to strategic points in the Persian Gulf has always accorded them a big economical significance.Advertising We will write a custom essay sample on The UAE Islands specifically for you for only $16.05 $11/page Learn More It should be observed here that this great importance directly associated with the location of the islands does not only extend to Iran and the Emirates, who are said to be the largest claimers of the land, but far beyond. The ownership disputes over the islands dates back over one hundred years ago, and this has consistently drawn the attention and concern of the international communities onto the matter. The three is lands belonging to the UAE were taken years ago by the Iranian government and the conflict began to rise again due to Iranian pressures. This big concern about the islands was more of a regional matter than anything else, and in that case, there were unsuccessful interventions by the British forces in the late 1960s, to ensure that both Iran and the UAE had equal control over one of the islands that was of great economical importance. This memorandum of understanding granted the two states equal share on the economic outcomes of Abu Musa Island. However, none of the two countries could renounce full claims on the island’s sovereignty. These new developments had occurred as a result of Britain’s announcement in the late 1960s that it intended to vacate the region by the end of the year 1971. The Iranian government had highly disputed this decision claiming their own historic rights on the highlands, and this would eventually see their troops forcibly gain control over t he islands towards the end of 1971 (Mobley, 2003). However, Iran was obliged to abandon this misguided claim following a referendum that was conducted on Bahrain under the supervision of the United Nations, but this did not stop them from having full control and authority over the islands.Advertising Looking for essay on government?

The Emirates, however, came up with claims that Arab leaders had ruled the islands for over two hundred years. Iran had tried to raise an ownership claim to the three islands in the early 1920s, but this move was quickly opposed by the British, who had a different perspective on the matter. This would ensure that the control of the three i slands was retained by Sharjah. The latest tensions on the matter escalated in the early 1990s, when the Emirates accused the Iranians of violating the agreement that gave them an equal authority over the Abu Musa Island. These claims were laid open in the year 2008 when it was reported that Iranians had already established maritime offices in the island, thus prompting serious protests from the Emirate’s side. This increased domination of the island by the Iranians appeared to give power to one side, while exploiting the other, as opposed to the requirements of the memorandum of understanding which had been signed by the two states in 1971, with regard to the control of the Abu Musa. As it would be observed, this prolonged dispute between Iran and the UAE with regard to the true ownership of the three islands has recently necessitated a number of events and incidents. For instance, the controversial and provocative issue has facilitated a wise initiative by the UAE in the re cent years, to resolve the matter through negotiations reached upon Iran and themselves, the International Court of Justice or any other suitable forum that involves the international attention. UAE’s government has constantly reaffirmed their claim to ownership of the islands, condemning Iran’s military occupation and domination on the matter (Kozhanov, 2011). In this context, the UAE has gone ahead to offer a number of suggestions on the most appropriate options that should be followed in addressing the matter.Advertising We will write a custom essay sample on The UAE Islands specifically for you for only $16.05 $11/page Learn More The first option would be engagement in direct bilateral talks between the two major rivals on the matter; Iran and the UAE. This approach will address the question of sovereignty of the three Islands, among other key issues surrounding the Iranian occupation and control of the islands. There are no any precon ditions that have been set by the UAE against the Iranian government, as far as this approach is concerned. The other option that had been proposed by the UAE towards a permanent resolution on the issue was to seek the advice and judgment of international parties such as the International Court of Justice in The Hague. Even though the UAE had expressed their willingness to accept any ruling that might be reached upon by the ICJ regarding the sovereignty of the islands, Iranians have completely rejected anything to do with any of these two options. The above specific phenomenon had triggered new suspicions from the Iranian government who saw this as a plan to rob them of their sovereignty over the disputed islands (Anthony, 2010). In this regard, Iranians would later on accept to engage into bilateral talks on the matter, but on a number of conditions. The officials representing Iran on the matter had clearly expressed their complete unwillingness to tackle the question of the three islands’ sovereignty. According to the officials, their main concern on the talks would be aimed at resolving the misunderstandings between them and the UAE on this progressive issue. Even though the International law has been clear on its enforcements that sovereignty cannot be achieved through the way of coercion or military invasion, the presence of Iranians on the three islands continues to raise many questions. This, however, explains the reason as to why the Iranians have been unwilling to allow the involvement of the ICJ in this matter. This is simply because the international court is likely to rule in favor of the Emirates as far this issue is concerned, owing to the weakness stand of the Iranians in terms of the international law on this specific matter. However, Iran has over the years used this as their vantage point from which they can have full control over the matter, since the international court can only exercise their jurisdiction power on the matter where t he involved parties have given in to referral of a dispute, and that is something which they have refused completely.Advertising Looking for essay on government? Let's see if we can help you! Get your first paper with 15% OFF Learn More The above approach by the UAE was intended to effectively improve the conflicted relationship between Iran and the UAE, but it has only succeeded at raising unanticipated tensions on whether there would ever be a permanent resolution on this matter, which has threatened to tear the interests of the two countries apart. This is contained in the interests of each of the two rivals to have a sovereign power and authority over the three islands, which are certain to generate significant economical benefits, among other attractive alternatives. Moreover, the outcomes of this move by the UAE would be even more of a serious conflict between the two nations, than an attempt to bring them together through a permanent resolution, as it was previously intended. UAE’s efforts to regain control of the islands from the Iranians through whichever means has subsequently been considered to be a move which is likely to severe more the diplomatic ties between this two adversaries and other gulf states (Nuruzzaman, 2012). This may also result to violence and attacks, considering the much-spread word that Iran has established a strong military presence on the disputed islands as a way of securing them from the Emirates. This security detail, as it will be observed, constitutes of both anti-ship and anti-aircraft missiles to ensure maximum safety measures of the islands from any point of attack. This exaggerated security concern is a clear indication that the Iranian government is not ready to surrender the sovereignty of the islands to any other state, and that they are willing to act in any possible manner against any plans to relieve them of this significant right. Some of the major consequences that are likely to sprout from this phenomenon would include poor social fabrics and disintegration of the close and multifaceted trade relationships that have existed between Iran and the UAE. As it would be observed, Iran-UAE economic ties have risen steadily over the past ten y ears. This however, would be expected, considering the fact that the Emirates have emerged as Iran’s key connection and access to global economy in the recent past, as trade sanctions against Iran continue to take serious effect on their economy (Ulrichsen, 2009). No wonder, major global traders such as China and Japan have started conducting bilateral economic activities with Iran, through the UAE. The flourishing Iran-UAE economical relationships, however, may be short-lived following Iran’s failure to honor the UAE’S decision on the islands’ issue. In the events arising from this phenomenon, there have been consistent concerns that the Iranian government poses the biggest threat to Emirate’s political, economical, and even national security. It leaves no doubt that this dispute over the islands has been the most persistent cause of bilateral tension between the two Gulf States, as it is observed from this essay. As a matter of fact, the islandsà ¢â‚¬â„¢ issue remains a constant irritant in the social and economical relationships of the two countries, thus undermining any development efforts applied by the countries. Even though this constant threat over the islands has never escalated to the levels of extreme violence, there have been increased concerns of late that these tensions may eventually result to serious bilateral tensions or conflicts. In order to contain the impact of all these potential consequences, Iranians should stop seeing themselves as an imperial power, and try to cooperate more intensively on the UAE’s idea of peaceful negotiations to resolve this big issue which has threatened to tear them apart.

Free Essays on Anti-semitism

European anti-Semitism was the building blocks for Nazi propaganda. European anti-Semitism is an outgrowth of Christianity. Since the time of the Roman Empire, Christian leaders preached boundlessly against Jews. It escalated from generation to generation, and as long as the Jews rejected Jesus as their Messiah, they were going against the whole belief system of Christianity. The idea that the Jews killed their savior also arose from that time period, bringing forward the notion that all Jews of forever were responsible for Jesus’ death. As the Medieval period came, the Christians’ hatred for Jews further articulated and was brought to a new level. The Christians in the medieval world saw Jews in twofold opposition to Christianity: they rejected his revelation and were his killers. Church members had much detested the Jews on the basis that they should have accepted Jesus as their Messiah. Consequently, persecution and killing of the Jews became a part of everyd ay life, leaving many regions of Western Europe without any Jews by the end of the sixteenth century. Entering the nineteenth century, German anti-Semitism went through an acute transformation. It was then that it made its change from a religious issue, to a very racial one. Germans naturally detested Jews with a passion. Nineteenth century Germans now saw Jews as the symbol for everything wrong in their declining economy, even though they made up but a mere one percent of the population. Soon the cultural taboos that had formerly shaped the moral fabric of Germany at the time lost all influence.

Free Essays on Anti-semitism After learning about the Holocaust, I’ve asked myself many times how this could have happened. Why would anyone believe it’s acceptable to massacre an entire people? This is my reasoning for writing my paper on how Christian theology influenced anti-Semitism. Much of the Holocaust appears to have it’s beginning with Christian theology. I will begin my paper with the early writings of Christians and continue chronologically until after World War II. The Apostle Paul was one the first people to criticize the Jewish people. At first, he tried to explain to the Christians not to adopt a superior attitude towards the Jews.

IF YOU DO BOAST, REMEMBER THAT IT IS NOT YOU THAT SUPPORT THE ROOT, BUT THE ROOT SUPPORTS YOU. [ROMANS 11] At one point this appeared to be Paul’s feeling towar ds the Jews and the Christians. His sentiment appeared to change, according to Christian suppressionists. In the text Romans, many of Paul’s statements were misinterpreted by those Christians to make themselves appear more superior to the Jewish people. †¦INCLUDING US WHOM HE HAS CALLED, NOT FROM THE JEWS ONLY BUT ALSO FROM THE GENTILES?

American history 1492-1865 Essay Example | Topics and Well Written Essays - 2000 words

American history 1492-1865 - Essay Example Numerous historians and novelists delve into the analysis of the civil war while focussing on various battles to paint a realistic image of events as they were. However, they lack consensus on issues that run deep and are pertinent to the motivation, reasons, and outcomes of the war. While there were numerous fronts of confrontation during the American civil war, this paper focusses on Gettysburg owing to the magnitude of the battle and outcomes. In addition, this paper employs the works of David Moore, Michael Shaara, and Edwin Coddington for the purposes of different opinions and from the viewpoints of various characters involved in the war. The named scholars are renowned for their quality analysis of historical events, which places their work at ease among their peers owing to significant research accompanied by lengthy bibliography essays. The scholars are in consensus about whom the participants in the battle of Gettysburg are, and have been accorded enormous analysis based on their conduct during the war. The battle involved a confrontation of enormous magnitude between union and confederate forces at Gettysburg, Pennsylvania in 1863. The battle lasted three days and resulted in heavy casualties from either side before the confederates were forced into a retreat and subsequent surrender. In line with participants, well detailed biographies by the scholars illustrate the kind of leadership provided by the then generals during the civil war. The characters of great importance during the Gettysburg confrontation include General George Meade of the Union faction and General Robert Lee who led the confederate soldiers. While over 160,000 soldiers engaged in the battle, the confederates had fewer men compared to the Union front. The scholars share different opinions on the opposing sides with a clear inclination of whom they would support. An in-depth look at Coddington’s ‘The Gettysburg Campaign’, although not clearly stated his tilt towar ds the Union forces is revealed as the writer engages the reader in a detailed narration of the events. Coddington’s account of the campaign is regarded as a fine volume of events as they were and as such, it has been highly influential in shaping how society thinks of the battle. Moreover, Coddington’s analysis depicts a rough image of the generals that led the battle giving rise to different sentiments on his account. The writer cites the mistakes made by the confederate generals during the three-day battle while bravery is illustrated for officers involved in the repulsion of the Pickett’s charge. It is the writer’s belief that the Union’s victory can be attributed to General Lee’s contempt of his opponents, overconfidence, and poor organisation (Coddington 680). In essence, Coddington hold General Lee culpable for the failure to make a decisive strike on the first day of the battle where the writer suggests a different outcome for the en tire confrontation. This take absolves other perspectives such as lack of coordination, firepower, and ill-trained soldiers from all blame and setting it all on General Lee. Unfortunately, the writer’s work has always seized a unique spot among historians leaving almost no room for criticism. It has been argued that the writer relied on the General Lee’s use of the phrase ‘if practicable’ when issuing orders, which is seen as a suggestion rather than an order (Bowden and Ward

Employment Law Research Proposal Example | Topics and Well Written Essays - 250 words

Employment Law - Research Proposal Example However, if the IRS later reclassifies a contractor as an employee, the employer faces liability for back payroll taxes, possible criminal sanctions and invalidation of benefit plans." (2004) These are things to keep in mind when an organization is facing an audit from the Department of Labor. It would be best to thoroughly review the laws governing independent contractor categorization before the audit process begins in order to ensure that the independent contractors are properly classified. As far as the school bus accident is concerned, it would again be best to review the laws governing the liability of the organization when an accident involving an independent contractor is concerned. It is most likely that the liability of the accident will fall into the hands of the person who is actually at fault for the accident rather than the employing organization, as it may first appear. Since companies who hire independent contractors rarely carry insurance on these individuals, there may be a significant problem arise (Freelawanswer, 2010). An independent contractor gets into a car accident while on the employer's time, who is liable for the damage (201

The Cold War and U.S. Diplomacy Assignment Example | Topics and Well Written Essays - 1000 words

The Cold War and U.S. Diplomacy - Assignment Example This era of panic is termed as the Cold War. This paper is all about the famous President Truman and the declaration he made at this point in time. A situation that required US diplomatic efforts during President Truman’s time was when he tried to formulate a forum instead of the futile League of Nations. The new venture, United Nations Organization, aimed at dissolving the differences between nations without allowing them to lead to devastating wars. As the legacy of the League of Nations was criticized, the formation of a powerful and unbiased agency was a herculean task. Undoubtedly, its main intention was to gain a significant role for Americans in the international life, and he succeeded in its making to a great extent. However, there were a number of roadblocks amidst. The major barrier to the formation of the UN came from the Soviet Union as they were reluctant to join it. At this juncture, ( ac cited in American president: A reference resource),Truman managed to ensure their participation in the founding conference of United Nations Organization in San Francisco by sending a special emissary Harry Hopkins to Moscow. However, the San Francisco Conference ended in June 1945 after most of its participating nations, including the Soviet Union, signed the founding U.N. Charter. If Truman had not intervened with his diplomacy, the formation of UN would have been delayed (American president: A reference resource). The diplomatic doctrine that Mr. President followed was that United States would provide political, economic, and military service to all democratic nations which were under the threat of external or internal authoritarian forces. Evidently, the president indirectly mentioned the threat of communist countries especially from the Soviet Union to the democratic and capitalist countries in the Eastern Europe. He made this doctrine lucid in a speech delivered before the joint session of Congress on March 12, 1947. The immediate reason for this spe ech was the declaration by the British government that it would no longer help the Greek government in its civil war against the Greek communist party by providing military and economic assistance. In his speech, Truman urged the Congress to support the Greek government against the communists. For, the US believed that Soviet Union had been supporting the Greek communist party, and unfortunately if the communist party won the war, the Soviet Union would ultimately influence the policies of the Greek. America never wanted the communist party to flourish posing a threat to capitalism and imperialism. Truman (as cited in The Truman doctrine 1947) believed that proliferation of communist party will be a serious threat to the US; and as the relationship between the US and Soviet Union had been worsening, America viewed the Soviet intervention in Greek and Turkish affairs with suspicion. The withdrawal of Britain from providing assistance to Greece made the declaration of Truman’s diplomatic doctrine imminent. To many, Truman’s doctrine may seem wise political manipulation to keep U.S. rivals far off. But to some extent, it could put forth some effects on the US and other countries as well. One of the major demerits of the communist form of government that the world witnessed was that the rulers went totalitarians once they got into power.

Qualitative Tests Used For Carbohydrates Biology Essay

Qualitative Tests Used For Carbohydrates Biology Essay Carbohydrates are an essential component of our diet and an important source of energy for us. Most of the things generally included in our diet have a large ratio of carbohydrates present. Also the patients suffering from Diabetes excrete huge amounts of sugar in their urine which needs to be estimated. The purity of carbohydrates can also be checked by methods which can qualitatively estimate particular sugars. Hence the need for carbohydrate estimation arose. We have been estimating carbohydrates qualitatively since school time but it was just confined to observing a colour change or a coloured precipitate to detect the presence of a carbohydrate. None of us ever thought that these qualitative tests are highly sensitive and provide much more information than just detecting the presence of a sugar. In this study conducted, two qualitative tests used for carbohydrates were studied: Benedicts test and Seliwanoffs test. Benedicts test is a test used for detecting the presence of Reducing Sugars. The test was performed using Glucose which is the most common reducing sugar. Sucrose was used as a negative control. Different concentrations of glucose were tried ranging from 1.6 M to 1.6 mM and from 4% to 0.25%.Also along with concentration the amount of sugar was varied to find the sensitivity limits and the limitations of the test. The result of Benedicts test is usually a brick red precipitate but with some modifications different colours of solutions and different amounts of precipitate could be observed with slight variation in the concentration and amount of sugar. This suggests that this test being Qualitative is not only an indicator of the presence or absence of a reducing sugar but can also be used to roughly estimate the concentration of sugar present. It can be very useful in estimation of the concentration of sugar present in the urine of diabetic patients. Seliwanoffs test is a qualitative test used for distinguishing between Aldoses and ketoses. Ketoses form a cherry red condensation product whereas Aldoses react to form a blue-green condensation product, which may further change to a peach product. The test was performed using fructose as the sample sugar. Various concentrations of Fructose were used ranging from 4% to 0.01% to find the sensitivity limits and the limitations of the test. The test appeared to be sensitive even at 0.01% showing a very faint red colour. There was a huge variation in the intensity of colour obtained at different concentrations of sugar. But the drawback of the test was that the red colour of the solution was not stable. It intensified with increase in the duration of time. 2. INTRODUCTION Carbohydrates are the most abundant bio molecules on Earth. Each year, photosynthesis converts more than 100 billion metric tons of CO2 and H2O into cellulose and other plant products. Certain carbohydrates (sugar and starch) are a dietary staple in most parts of the world, and the oxidation of carbohydrates is the central energy-yielding pathway in most non-photosynthetic cells. Insoluble carbohydrate polymers serve as structural and protective elements in the cell walls of bacteria and plants and in the connective tissues of animals. Other carbohydrate polymers lubricate skeletal joints and participate in recognition and adhesion between cells. More complex carbohydrate polymers covalently attached to proteins or lipids act as signals that determine the intracellular location or metabolic fate of these hybrid molecules, called glycoconjugates. .Carbohydrates are polyhydroxy aldehydes or ketones, or substances that yield such compounds on hydrolysis. Many, but not all, carbohydrates have the empirical formula (CH2O)n; some also contain nitrogen, phosphorus, or sulphur. There are three major size classes of carbohydrates: monosaccharides, oligosaccharides, and polysaccharides Classification Carbohydrates can be classified on the basis of the various characteristics they possess. They can be classified on the basis of the number of carbon atoms in the sugar chain, the terminal functional group in the chain, the number of sugar subunits and the reducing activity of the sugar units. Depending on various basis they are of several types: A. According to the number of carbon atoms in the sugar chain: 1. Trioses: contain 3 carbon atoms (e.g. glyceraldehyde). 2. Pentoses: contain 5 carbon atoms (e.g. ribose). 3. Hexoses: contain 6 carbon atoms (e.g. glucose). B. According to the terminal functional group in the sugar chain: 1. Aldoses: contain terminal aldehyde group (-CHO) (e.g. glucose). 2. Ketoses: contain terminal ketone group (C=O) (e.g. fructose). C. According to the number of sugar subunits: 1. Monosaccharides: Monosaccharides, or simple sugars, consist of a single polyhydroxy aldehyde or ketone unit. The most abundant monosaccharide in nature is the six-carbon sugar D-glucose, sometimes referred to as dextrose. 2. Oligosaccharides: Consist of short chains of monosaccharide units(2-10) joined by characteristic linkages called glycosidic bonds. The most abundant are disaccharides, with two monosaccharide units. e.g. sucrose (cane sugar), which consists of the six-carbon sugars- D-glucose and D fructose. 3. Polysaccharides: The polysaccharides are sugar polymers containing more than 20 or so monosaccharide units, and some have hundreds or thousands of units. Some polysaccharides, such as cellulose, are linear chains; others such as glycogen, are branched. Both glycogen and cellulose consist of recurring units of D-glucose, but they differ in the type of glycosidic linkage and have different properties and biological roles. . D. According to the reducing activity of the sugar unit: Carbohydrates that can undergo oxidation are called reducing sugars. This depends on the presence of an exposed carbonyl group. 1. Reducing sugars: Certain sugars with a free carbonyl carbon can be oxidized by oxidizing agents such as ferric (Fe3) or cupric (Cu2) ion. The carbonyl carbon (anomeric carbon) is oxidized to a carboxyl group. Such sugars capable of reducing ferric or cupric ion are called Reducing sugars. e.g. lactose, maltose. 2. Non-reducing sugars: Sugars like sucrose contain no free anomeric carbon atom since the anomeric carbons of both monosaccharide units are involved in the formation of glycosidic bond. Therefore it is a Non-Reducing sugar. 2.1 Biochemical Tests for Carbohydrates The biochemical tests for carbohydrates can be divided into two categories: Qualitative Tests- These tests are performed to detect the presence of carbohydrates in a test sample. They are also used to detect the type of carbohydrate present. There are different types of qualitative tests for different types of carbohydrates. e.g. Fehlings and Benedicts test for reducing sugars, Seliwanoffs test for ketoses, Iodines test for starch,Bials test for detecting pentoses etc. They are not very sensitive as compared to quantitative tests and cannot estimate the exact amount of carbohydrates present but show some difference in the observation with variation in the amount of carbohydrate hence, can be used to make a rough estimate of the amount of sugar present. Quantitative Tests- These tests are the advanced form of qualitative tests and can be used to estimate the amount of carbohydrate present in a given sample. These tests use particular chemicals which form coloured complexes with sugars which can then be read at certain wavelengths using a spectrophotometer. Their absorbance can then be used to estimate the exact amount of carbohydrate present in the sample. e.g. Anthrone test, DNS Method, Phenol- Sulphuric Acid Method etc. 2.11 Qualitative Test Flow Chart for classifying an unknown carbohydrate A. Molisch Test Molisch test is used to distinguish between carbohydrates and non- carbohydrates. It is the preliminary test used to detect the presence of carbohydrates in a sample. Principle It uses concentrated sulphuric acid as a Dehydrating acid which dehydrates all carbohydrates to form Furfural or 5-hydroxymethylurfural from reaction of sulphuric acid with pentoses and/or hexoses. These products condense with ÃŽ ±-naphthol to yield a purple condensation product. B. Iodine and Potassium Iodide Test This is a test used particularly to detect starch and glycogen. Starch gives a blue-black colur with potassium iodide whereas glycogen gives reddish-brown colour. Principle Starch contains ÃŽ ±-amylose, a helical saccharide polymer, and amylopectin. Iodine forms a large complex polysaccharide with the ÃŽ ±-amylose helix, producing a blue-black colour. Simple Oligosaccharides and Monosaccharides do not form this complex with Iodine. Thus, the I2/KI test can be used to distinguish starches from other carbohydrates. C. Bials Test Bials test is used to distinguish between pentoses and hexoses. Principle This test uses concentrated hydrochloric acid as the dehydrating acid and orcinol with a trace of iron(III) chloride as the condensation reagent.. Pentoses subjected to the test yield a blue or green condensation product, while hexoses yield a muddy brown to grey condensation product. Pentose Dehydration Product Blue or Green condensation product (Furfural) Hexose Dehydration Product Muddy brown-Grey condensation product (5-hydroxymethylfurfural) D. Seliwanoffs Test Seliwanoffs test is used to distinguish between aldoses and ketoses. Principle This test uses 3N hydrochloric acid as the dehydrating agent as resorcinol as the condensation reagent. When mixed with Seliwanoffs Reagent, Ketopentoses react within 2 minutes to form a cherry red condensation product. Aldopentoses react after 2 minutes to form a blue-green condensation product, which may further change to a peach product. Fructose Hydroxy-methyl Cherry-Red Complex Furfural Identifying Reducing Sugars All mono and disaccharides with a free aldehyde or keto group act as reducing agents in alkaline solutions. The reducing properties of sugars are dependent upon the presence of actual or potential aldehyde or ketone groups. The enolization of sugars under alkaline conditions is an important consideration in reduction tests. The ability of a sugar to reduce alkaline test reagents depends on the availability of an aldehyde or keto group for reduction reactions. A number of sugars, especially disaccharides or polysaccharides have glycosidic linkages which involve bonding between each group, and hence there is no reducing group on the sugar; such as the case for sucrose, trehalose, inulin, glycogen, starch, and dextrin. In the case of reducing sugars, the presence of alkali causes extensive enolization especially at high pH and temperature. This leads to a higher susceptibility to oxidation reactions than at neutral or acidic pH. These sugars, therefore, become potential agents capable of reducing Cu+2 to Cu+, Ag+ to Ag and so forth. Reducing sugars can react with many different oxidizing agents. Fehlings test, Benedicts test and Barfoeds test have been used to distinguish between monosaccharides and disacc harides Monosaccharides fluctuate between a ring open form and a ring closed form. The ketone (-C=O) group, for Fructose and the aldehyde group (-CHO), for Glucose in the ring open forms can be reduced using these tests. Some sugar units in disaccharides also fluctuate between a ring open form and a ring closed form. These disaccharides are also reducing sugars because the ring open form has a ketone or aldehyde to react. Sucrose is one of the few disaccharides that do not have a ring open form so it is a non-reducing sugar.  ­Ã‚ ­Ã‚ ­ Ring Open Fructose and Ring Closed Fructose Ring Open Glucose and Ring Closed Glucose Reducing Sugars are oxidized by copper (II) ions. Benedicts reagent and Fehlings Reagent are mildly basic solutions whereas Barfoeds Reagent, a mildly acidic solution. The presence of red copper (I) oxide precipitate indicates that the saccharide has reduced the copper (I) ions. E. Fehlings test Principle Fehlings test uses a mixture of fehlings solution A and B. Fehlings solution A consists of copper(II) sulphate dissolved in dilute sulphuric acid. Fehlings solution B is sodium potassium tartarate dissolved in dilute NaOH. Both the solutions are mixed in equal proportions and used as fehlings reagent. This reagent is used as a general test for detecting reducing sugars. A reducing sugar reduce copper(II) ions to copper(I) oxide, forming a red precipitate. CuSO4Cu++ + SO4 2 Cu++  + Cu+ Glucose (Reducing Sugar) Cu+Cu2O (red precipitate) Cuprous Oxide F. Benedicts test Principle Benedicts test uses a mixture of copper(II) sulphate, sodium citrate, and sodium carbonate in a mildly basic solution. This reagent is used as a general test for detecting reducing sugars. A reducing sugar reduce copper(II) ions to copper(I) oxide, forming a red precipitate. CuSO4Cu++ + SO4- (Copper Sulphate) (Cupric Ion) (Sulphate Ion) 2 Cu++  + Cu+ Glucose (Reducing Sugar) Cu+Cu2O (red precipitate) Cuprous Oxide G. Barfoeds Test Benedicts test gives positive test results for all reducing sugars. However, not all reducing sugars react at the same rate. With different oxidizing agents, disaccharides are considerably less reactive compared to monosaccharides. A positive Barfoeds test result is similar to that observed with Benedicts solutions. Monosaccharides give positive Barfoeds test results within 2-3 minutes, while disaccharides do not react under the same conditions. Principle Barfoeds test uses copper(II) ions in a slightly acidic medium. If the reaction time is carefully monitored, this test can be used to distinguish reducing monosaccharides from reducing disaccharides. Reducing disaccharides cause the formation of copper(I) oxide after approximately 10 minutes.

Determination of Total Carbohydrate by Anthrone Method Principle Carbohydrates are first hydrolysed into simple sugars using dilute hydrochloric acid. In hot acidic medium glucose is dehydrated to hydroxymethyl furfural. This compound forms with anthrone a green coloured product with an absorption maximum at 630 nm. HCl anthrone Carbohydrate furfural/hydroxymethyfurfural Green product (630 nm) B. Phenol Sulphuric Acid Method for Total Carbohydrate Principle In hot acidic medium carbohydrates are dehydrated to furfural/hydroxymethyl furfural. This forms a green coloured product with phenol and has absorption maximum at 490 nm. H2SO4 phenol Carbohydrate furfural/hydroxymethylfurfural Green product (490 nm) C. Determination of Reducing Sugars by Nelson-Somogyi Method The Nelson-Somogyi method is one of the classical and widely used methods for the quantitative determination of reducing sugars. Principle The reducing sugars when heated with alkaline copper tartarate reduce the copper from the cupric to cuprous state and thus cuprous oxide is formed. When cuprous oxide is treated with Arsenomolybdic acid, the reduction of molybdic acid to molybdenum blue takes place. The blue colour developed is compared with a set of standards in a colorimeter at 620 nm. Cu2O+ Arsenomolybdate Molybdenum Blue (Cuprous Oxide) (500 nm) D. Estimation of Reducing Sugar by Dinitrosalicylic Acid Method This method is an alternative to Nelson-Somogyi method. It is a simple, sensitive and adoptable method during handling of a large number of samples at a time. However,  enzymatic  methods are usually preferred to DNS due to their specificity. Principle 3,5-Dinitrosalicylic acid   is an  aromatic compound  that reacts with reducing sugars to form  3-amino-5-nitrosalicylic acid, which absorbs  light  strongly at 540  nm. 3,5-Dinitrosalicylic acid 3-amino-5-nitrosalicylic acid E. Determination of Glucose by Glucose Oxidase Method Glucose is a widely distributed simple sugar with an active aldehyde group. Estimation of glucose by glucose oxidase gives the true glucose concentration eliminating the interference by other reducing sugars. Principle Glucose oxidase catalyses the oxidation of alpha-D-glucose to D-glucono-1, 5 lactone (gluconic acid) with the formation of hydrogen peroxide. The oxygen liberated from hydrogen peroxide by peroxidase reacts with the O-dianisidine and oxidises it to a red chromophore product.

Step 3- Add 2 ml of Benedicts reagent in all the test tubes. Step 4-Transfer all five tubes to the boiling water bath provided and record the time for the appearance of precipitate. Step5- Make a subjective analysis of the colours observed. A scale of + to +++++ can be used to record the depth of the colour, from lightest to darkest. 4.11 Effect of variation in Carbohydrate Concentration (in M) The concentration of glucose was varied from 1.6 M to 1.6 mM keeping the reaction volume constant to 3 ml. The upper and the lower sensitivity limits and the optimum molar concentration of glucose was found for the test through subjective analysis. 4.12 Effect of Reaction Volume The reaction volume was reduced from 3 ml to 1.5 ml for all the concentrations of glucose ranging from 1.6 M to 1.6 mM to find any difference in the sensitivity range and the optimum molar concentration of glucose for the test. 4.13 Effect of variation in Carbohydrate Concentration (in %) The concentration of glucose was varied from 4% to 0.25%. Also the reaction volume was changed and the analysis was performed in two sets. The volume of reagent used was 5 ml whereas the volume of samples all concentrations in Set A and B were 50ÃŽ ¼l and 25ÃŽ ¼l respectively. 4.14 Effect of variation in Sample Volume The volume of glucose was varied for the same concentrations 4% to 0.25% to see the changes in the colour of solution obtained and at the same time find the upper and lower limits at which the test still remains sensitive. The analysis was performed in 6 sets with the following volumes of glucose: 200ÃŽ ¼l, 100ÃŽ ¼l, 50ÃŽ ¼l, 25ÃŽ ¼l, 12.5ÃŽ ¼l and 6.25ÃŽ ¼l. 4.15 Effect of Reaction Volume on the results obtained. Of the various sets tried 5 ml of Benedicts reagent and 200ÃŽ ¼l of sample gave the best results. To verify the consistency of results obtained the reaction volume was reduced.

RESULTS AND DISCUSSION 6.1 Benedicts Test 6.11 Effect of variation in Carbohydrate Concentration (in M) It can be observed that 0.1 M is the optimum concentration of sugar for Benedicts reaction with the reaction volume of 3 ml since the highest amount of precipitate is formed at 0.1 M. Also the supernatant obtained after centrifugation is colourless which suggests that the reaction is completed and there is no unused reagent left. Concentrations less than 0.1 M show decreasing amounts of precipitate and the colour of the supernatant is also increasingly blue. This suggests that as the concentration of sugar is lowered the amount of unreacted Benedicts reagent increases which leaves the solution blue even after the reaction completes. 1.6 mM sugar sample shows a negligible amount of precipitate formation which suggests that the reaction is not sensitive for concentrations lower than 1.6 mM. For concentrations higher than 0.1 M the amount of precipitate formed again decreases with increase in concentration which suggests that the concentration is too high as compared to the amount of reagent used and hence no more precipitate is formed after the reaction completes. 6.12 Effect of variation in Reaction Volume The reaction volume was reduced to half but has no effect on the results of the experiment. 0.1 M is the optimum concentration of sugar for the reaction with the reaction volume of 3 ml since the highest amount of precipitate is formed at 0.1 M. Also the supernatant obtained after centrifugation is colourless which suggests that the reaction is complete and there is no unused reagent left. Concentrations less than 0.1 M show decreasing amounts of precipitate and the colour of the supernatant is also increasingly blue. This suggests that as the concentration of sugar is lowered, the amount of unreacted reagent increases which leaves the solution blue even after the reaction completes. 3mM and 1.6 mM sugar samples show a negligible amount of precipitate formation which suggests that the reaction is not sensitive for concentrations lower than 3 mM with a reaction volume of 1.5 ml. For concentrations higher than 0.1 M, the amount of precipitate formed again decreases with increase in concentration which suggests that the concentration is too high as compared to the amount of reagent used and hence no more precipitate is formed after the reaction completes. 6.13 Effect of variation in carbohydrate concentrations (in %) The highest amount of precipitate was formed in 1% sugar sample but there was no consistency in the observations due to incorrect preparation of reagent. During the preparation of reagent instead of mixing Sodium citrate and Copper Sulphate together in hot water they were dissolved separately and then mixed. Also the solution was not made up to 500 ml with distilled water rather measured amount of water was added to the solution to make it 500 ml which made the solution dilute and hence gave incorrect results. 6.14 Effect of variation in Sample Volume Different volumes of sugar were tried for all the different concentrations. There was a variation in the colours obtained. 200ÃŽ ¼l of sugar reacted with 5 ml of reagent showed maximum variation in colours at different concentrations: Reddish Brown, Brown, Green, Greenish blue and dull blue obtained at 4%, 2%, 1%, 0.5% and 0.25% respectively. Sets with 12.5ÃŽ ¼l and 6.25ÃŽ ¼l of sugar volume did not show any noticeable changes in colour which suggest that the volume of sugar solution was not enough for the reaction to take place. 6.15 Effect of reduction in the reaction volume Reduction in the reaction volume made no difference to the variation in colours obtained at different concentrations of sugar which suggests that Benedicts reagent and glucose can be reacted in this ratio in any volume to estimate the concentration of glucose present in an unknown sample. 6.2 Seliwanoffs Test 6.21 Effect of variation in carbohydrate concentration (in %) A cherry red colour is observed for all the concentrations of Fructose used but the intensity of colour obtained decreases with decrease in concentration. The highest intensity is observed at 4% sugar concentration. 0.015% which is the lowest concentration of sugar used gives a very faint red colour which cannot be taken as pos

Metaphors :: Argumentative Philosophy Argument Papers

Metaphors With the possible exception of completely formal exercises in logic, philosophy is thoroughly metaphorical and largely conditional. Moreover, the purposes served by metaphors and conditionals in it are similar. Metaphors ask us to imagine the world in a new way, while conditionals may ask to imagine a new world. Yet some conditionals and metaphors are incompatible. There are limits to how metaphors can occur in conditionals, and how conditionals can themselves be metaphors. Specifically, only certain kinds of metaphors can be accommodated in the antecedents of conditionals, and even then only within a restricted class of conditionals. This paper focuses on the linguistic tension between metaphors and conditionals. I argue that this echoes a tension at the heart of philosophy between two modes of philosophizing: a speculative-revisionary mode that is metaphorical and an analytic-explanatory mode that is conditional. The tasks are generally complementary so that the difference can be i gnored with impunity. However, if we do not respect that difference, we may find ourselves analyzing metaphors and seeing logical analyses as metaphorical, and thus missing the point on both fronts. Life is not really a bowl of cherries, and kangaroos do have tails. We know this full well, and yet are willing to entertain their negations in one way or another--the former as metaphor, the latter as counterfactual hypothesis. These are common moves to make in trying to understand the world — indeed, characteristically philosophical moves — but they are very different in kind. Their similarities, differences, and conflicted interaction reveal something about metaphors and conditionals, but mostly about philosophy itself. Specifically: (1) "Philosophy" is a term that covers an extraordinary array of discourses, but with the possible exception of completely formal exercises in logic, philosophy is thoroughly metaphorical and largely conditional. (2) Some conditionals and metaphors, however, are incompatible. There are limits to how metaphors can occur in conditionals, and how conditionals can themselves be metaphors. Thus, (3) there is a tension at the heart of philosophy between two moments to philosophy or modes of philosophizing, a speculative, radical-revisionary mode that is metaphorical, and an analytic-explanatory mode that is conditional. Philosophers have special reason not to mix their metaphors (at least not with their conditionals). In this paper, I will focus on that linguistic tension. Â §1. Metaphors in Philosophy: Metaphors are invitations to see things in a new way — Communism as a spectre haunting Europe, philosophy as a series of footnotes to Plato, or all the world as a stage.

Response to Destros claim on Faust

Response to Destros claim on Faust Introduction The character of Faust and, most importantly, whether he is qualified as a heroic figure, has occupied critics for a long time. Looked at from the standard moral standpoint, Destro says: We would be forced to decant the apparent heroism we were meant to accord him. That he was eventually saved in spite of all the morally questionable deeds he had committed seems the only reason why anyone might consider him heroic. Destro is of the view, however, that we would be wrong to subject Faust to standard morality.Advertising We will write a custom essay sample on Response to Destros claim on Faust specifically for you for only $16.05 $11/page Learn More I do agree with Destro’s assertion that it would be practically impossible to find any moral or heroic merits to the character of Faust. This is particularly so if one was to base his/her argument on the contemporary understanding of morality. It would still be problematic for one to apply the ph ilosophical notion of morality during Goethe’s time. In this essay, I will show that Destro’s view presents the most viable manner of comprehending Faust’s character. Discussion Faust was never meant to be judged using standard morality. Destro fields the assertion that in the eyes of his creator, Faust was already a morally decadent character. He was probably meant to be immoral from the viewpoint of standard morality (Destro). This would be supported by his egoistic and hedonistic attitude that runs throughout the text. It leads Destro to conclude that â€Å"the salvation of Faust, the magician, the robber, the instigator of murderers, sounds like a mockery of any kind of ethical judgment on him†. Why then would Goethe have Faust saved at the end? Here, Destro interprets it to mean what we were to subject Faust to was not the standard morality but that of the superman: â€Å"In reality, the law that Faust follows is not that of morality in its everyday meaning, which from Moses to Kant was rooted in our relation of responsibility to others but rather the immoral ‘morality’ of superman for whom the supreme law is self-realization†. Faust is immoral. His immorality can be understood from two perspectives: his immoral actions are either willingly immoral or they are immoral due to the influence of Mephistotles (Destro). For Goethe to put across the notion that he is willingly immoral, Faust has consistently been characterized as a man of action, one who is moved by profound inner passions to do things that are not always right. For instance, Faust seems to lack capacity to face penance for deserting Gretchen and chooses the dramatic, and relatively easier, route of appropriating Mephistopheles’ powers to save her. This act is Faust’s own decision and cannot be blamed on Mephistotles. It is the result of the guilt that Faust feels for having abandoned Gretchen: â€Å"Let past be past I say! / Youâ₠¬â„¢re destroying me!† (Goethe). Destro contrasts Faust’s behavior with Gretchen’s who is ready to face death rather than escape from prison in the company of Faust and Mephistopheles. To again reinforce the fact that he can be blamed for his immorality, Goethe has Faust willingly get into a wager with Mephistopheles:Advertising Looking for essay on american literature? Let's see if we can help you! Get your first paper with 15% OFF Learn More â€Å"Have no fear I’ll break this pact! The extreme I can promise you: it is All the power my efforts can extract. I’ve puffed myself up so highly I belong in your ranks now† (Destro). His intentions in doing so are in no way noble since what he seeks in his involvement with Mephistopheles are pleasures that are both egoistic and hedonistic. He, therefore, cannot be objectively argued to be a victim of Mephistopheles. From a moral point of view, he is responsible for his actions and would be expected to atone for them in a morally apt way. Faust is given to an avid need for humanly pleasures. He portrays little responsibility in giving in to the desires of the flesh, a case in point being his lust for Gretchen. He has his way with her and leaves her, this leads to her eventual death. He shows great vanity when he accepts Mephistopheles offer to restore his youthfulness. On not finding any value in life after a spirit rejects his assertion that he and it are one, he considers committing suicide and it is only Easter bell that distracts him.Advertising We will write a custom essay sample on Response to Destros claim on Faust specifically for you for only $16.05 $11/page Learn More From the Dungeon scene, more proof can be found to show that Faust is indeed a negative figure. Foremost, Faust’s rescue plan is motivated by the wrong impetus: his remorse and not necessarily his concern for Gretchen. This can be interpreted as a p roof of his egoistic nature. When he opens Gretchen’s cell, she thinks that time of her execution has come. She rues her death and her lover’s absence: â€Å"’I’m still so young, so young! / And yet I’ll die!/I was lovely too, that was my Ruin/ My love was near, now he’s gone /The garland’s torn: the flowers are done† (Goethe). To this lament, Faust declares: â€Å"How shall I endure this misery, say!† (Goethe). This declaration is an evidence of his inner guilt and anguish, the feeling that he seeks to assuage by freeing Gretchen. More profoundly though, Faust’s attempt to save Gretchen is a sign of a much serious flaw; Faust is obviously quite disinclined towards penance. Gretchen’s being in prison is partly his fault. Had he pursued love rather than lust when he first sought to woo Gretchen, she would not have been facing death. He is willing to disregard the past as evidenced by his saying: â€Å"Let p ast be past I say! / You’re destroying me!† (Destro) This aspect to his character, this proclivity for immorality, Destro says that he cannot be fully blamed on his flawed fictive character but rather should be analyzed from the point of view of the function that he was meant to fulfill by the playwright (Destro). This is where Destro draws us to the possibility that Goethe obliterated all possibility of our having a dilemma regarding the morality, or a lack, thereof, of Faust. In doing this, Goethe is foregrounding the need for us to overcome the hurdle of morality as it is conceptualized in our everyday lives. It is only in doing this that the real spirit of Faust would be comprehended. It is not because of his actions that Faust is eventually saved. Rather, it is because of his attitude, his need to understand the world and his unrelenting pursuit of these goals. Faust is a seeker of knowledge; this quest for knowledge occupies his whole life. He is driven by a great need to understand the nature of things, thereby, studying a number of disciplines including law, medicine, philosophy and theology as seen in scene I. â€Å"Ah! Now I’ve  done  Philosophy,Advertising Looking for essay on american literature? Let's see if we can help you! Get your first paper with 15% OFF Learn More I’ve finished Law and Medicine, And sadly even Theology: Taken fierce pains, from end to end. Now here I am, a fool for sure! No wiser than I was before† (Destro). As Destro says, Faust’s frustration, at the beginning of the play, is understandable: â€Å"Having devoted the whole of his life to study, and mastered whatever culture of his time could offer, Faust then discovers, at the ends of a life of sacrifice, renunciation, and contempt from his ‘success,’ the vanity of his efforts† (Destro). He knows all there is to know but he still is not fulfilled. At this juncture, Faust is ready to do all it takes in order to find the all elusive fulfillment. In doing this, Faust is being both true to himself and honest to himself. And for this, he is saved. Destro argues that it is not for what Faust does but rather for what he had been that he was eventually glorified (Destro). In essence, this means that â€Å"his actions are measured, not accordin g to moral criteria (in other words, responsibility towards others) but according to the criterion of how far he corresponds to the law of his actual character† (Destro, 72). In living up to the essence of who he is, Faust is found worthy of going to heaven. Conclusion While there are many things that are contentious in the play, a few things come out very clearly. One is that Faust is decidedly an immoral character. Subjected to whatever standards of morality, it would be practically impossible to find him otherwise. Two, he is saved at the end. Less clear, however, is why Goethe chose to glorify Faust at the end. And the explanation forwarded by Destro is the most plausible one for explaining this paradox. Destro, Alberto.

Erre Moscia - Dispelling Linguistic Myths and Legends

Erre Moscia - Dispelling Linguistic Myths and Legends ​ The bulk of our linguistic competency is learned at an early age- normally before we even show signs of having acquired this ability. We listen to pronunciations, intonations and cadences, and use it all to fashion our own way of speaking. As adults, we can watch this process taking place in young children learning to talk. What we dont usually observe is that we begin to form opinions about another person based solely upon the way he or she speaks. Accents define us in more ways than we care to admit. Usually these preconceptions remain subconscious, only revealed, for example, when we believe someone with a heavier accent less intelligent than ourselves. Other times, the notions are much closer to the surface.One such highly debated presumption of Italian phonology centers on the misunderstood letter r which is typically pronounced as an alveolar trill in the front of the mouth. However, in some parts of Italy, notably Piedmont and other parts of the northwest near the French borde r, r is produced as a uvular sound in the back of the mouth. This is known as erre moscia or soft r and many Italians have crowned this unfortunate pronunciation wrong, going so far as to say that all those who speak with erre moscia are either snobby or have a speech impediment. Before making such assumptions about erre moscia, we must understand a few simple facts about its background. The History of R The letter r has a distinct history in many languages. In the phonetic table of consonants it hides under the label liquid or approximant, which are just fancy terms for letters halfway between consonants and vowels. In English, it is one of the last sounds to be developed, possibly because children arent always certain what people are doing to produce the sound. Researcher and linguist Carol Espy-Wilson used an MRI to scan the vocal tract of Americans saying the letter r. In order to produce r, we must constrict our throats and lips, position our tongue and engage the vocal cords, all of which requires a lot of well-timed effort. She discovered that different speakers use different tongue positions, yet exhibit no change in the sound itself. When a person does produce a sound differing from normal r, that person is said to exhibit signs of rhotacism (rotacismo in Italian). Rhotacism, coined from the Greek letter rho for r, is an excessive use or peculiar pronunciation of r. Why Piedmont? The phrase no man is an island relates just as well to human languages as to human emotions. Despite the efforts of many language purists to prevent influences from other languages entering their own, there is no such thing as an isolated linguistic environment. Wherever two or more languages exist side-by-side, there is the possibility of language contact, which is the borrowing and intermingling of words, accents and grammatical structures. The northwest region of Italy, because of its shared border with France, is in a prime position for infusion and mixing with French. Many of Italys dialects evolved similarly, each changing differently depending on the language with which it came into contact. As a result, they became almost mutually incomprehensible. Once any alteration has taken place, it remains within the language and is passed from generation to generation. Linguist Peter W. Jusczyk has conducted research in the field of language acquisition. It is his theory that our capacity to perceive speech directly affects how we learn our native tongue. In his book The Discovery of Spoken Language Jusczyk examines a number of studies which demonstrate that from approximately six to eight months of age, infants can distinguish subtle differences in every language. By eight to ten months, they are already losing their universal ability to detect delicate phonetic differences in order to become specialists in their own language. By the time production begins, they are accustomed to certain sounds and will reproduce them in their own speech. It follows that if a child only hears erre moscia, that is how he will pronounce the letter r. While erre moscia occurs in other regions of Italy, those instances are considered deviations whereas in t he northwest region erre moscia is perfectly normal. It is no secret that r- at least in the beginning- is a very difficult sound to produce. It is one of the last sounds children learn to say correctly, and has proven a rather difficult hurdle for people trying to learn a foreign language who claim they cannot roll their rs. However, it is doubtful that people who speak with erre moscia have adopted that sound due to an inability to pronounce another kind of r. Speech therapists who work with children to correct a variety of impediments (not just for the letter r) say that they have never witnessed a case where a child substitutes a uvular r for another one. The idea doesnt make much sense because erre moscia is still a version of the letter (albeit not the popular one) and still requires complicated positioning of the tongue. More likely, a child will substitute the semivowel w sound which is close to the letter r and easier to pronounce, making them sound like Elmer Fudd when he shouted Dat waskily wabbit! As for a snobbish affectation, there are certainly examples of wealthy, prominent Italians who speak with this accent. Actors who wish to depict an aristocrat from the 1800s are said to adopt erre moscia. There are even more recent examples of wealthy Italians who speak with erre moscia, such as the recently deceased Gianni Agnelli, industrialist and principle shareholder of Fiat. But it should not be ignored that Agnelli was from Turin, the capital city of the Piedmont region where erre moscia is part of the regional dialect. Certainly the phenomenon of erre moscia in Italian speech is not the consequence of any one variable but rather a combination. Some people may choose to use erre moscia in an effort to seem more refined, though considering the stigma attached, it would seem to defeat the purpose. It doesnt appear to be a speech impediment because erre moscia is not any easier to produce than the normal Italian r. More likely it is the result of language contact with French and adoption as part of the native dialect. However there are still many questions surrounding this unusual sound and the debate will continue among speakers of Italian, both native and foreign.About the Author: Britten Milliman is a native of Rockland County, New York, whose interest in foreign languages began at age three, when her cousin introduced her to Spanish. Her interest in linguistics and languages from around the globe runs deep but Italian and the people who speak it hold a special place in her heart.

Organic and Natural Food Restaurants Research Paper

Organic and Natural Food Restaurants - Research Paper Example The business will measure the profit margin and rate of stock turnover as a way of evaluating the growth (Carmona, 2004). An indicator that the firm intends to use is the percentage in profit margin, as well as the number of consumers that the restaurant will command. Industry Maturity Sustainability of cash flow into the firm will act as a gauge, which measures the maturity of the firm. The firm expects to reach its maturity after the period of three years because it is a startup business. Since the product cycle of the restaurant would influence its maturity in the market, it intends to have a short product cycle. Another important factor that the business intends to consider in order to reduce its maturity age is the choice of products that it would introduce to the market. The business has forecasted its growth in the first year to be modest. In the second year, the restaurant will increase its stocks in response to market behavior. In the third year, it would stabilize its stock . The business anticipates its growth to follow the trends indicated in the graph below. Sensitivity to Economic Cycles The business intends to demonstrate sensitivity to the state of economy by conducting a survey on consumer trend in similar businesses before it rolls out its product. The knowledge of consumer economic status is crucial to the pricing strategy of the business. The prices of the business product determine the number of clients that the business would serve. Due to the sensitivity of this issue, the business will monitor consumer trends before introducing expensive products. Consumer behavior depends on geographical location and sociological influences. Consumers usually demonstrate negative or positive response to price changes, which would eventually influence the rate of stock flow (Anderson, 2008). Most businesses, which command large market share, are sensitive to the consumer behavior. The operation of the business in the city would make it handle a wide range of customers who are likely to project different product demand patterns. Highly demanded products would be a measure of how sensitive the business is to the immediate environment. Seasonality Product seasonality is crucial to the business success because it would influence customer retention of the business. The business intends to operate in all seasons; however, it would control its product supply during low seasons. The business target consumers demonstrate seasonal trends in buying behavior. The high season appears immediately after the consumers get their salaries or wages and the low season occurs during mid month. This seasonal trend would influence the sales of the restaurant. The business intends to characterize the high season with high product supply and reduce the product supply during low season. The same trend would also influence its pricing strategy in order to create a constant profit margin at the end of each month. The business innovation would be sensitive to s easonality. Changes in economic trends in the market might force the business to blend its products in response to this trend (Anderson, 2008). Technological Change The restaurant will use the internet technology to reach its customers. The Internet use is an option that the business intends to use in order to update its clients with the frequent changes in products and prices. Order placement and instant payment are some of the common trends that the business

The Providence Debate Research Paper Example | Topics and Well Written Essays - 2250 words

The Providence Debate - Research Paper Example The author considers that a balanced mixture of these two views offers a better perspective. The author proposes that God’s truth as revealed in the Holy Scriptures is reflected in some parts by the Calvinists view and in some parts by the Armininans and God’s truth regarding salvation is not monopolized wholly by just one of these two views. God Announced Salvation after the fall On the sixth day of creation, after forming everything which included the light, the firmament, the plants and the animals, God created man in His own image and put him in the Garden of Eden to dress it and to keep it; later Adam was joined by his wife Eve, the woman whom God formed from one of Adam's ribs.1 Adam and Eve had everything they needed and lived very close to God and just like in a fairy tale, they could have lived happily ever after. But they disobeyed God’s commandment: â€Å"But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die†.2 Thus the first man and woman fell to sin and the whole creation fell with them.3 The loving Almighty God, after the fall of man, even in the dawn of human history, had already announced the forthcoming salvation, as He said to the serpent: â€Å" And I will put enmity between thee and the woman and between thy seed and her seed: it shall bruise thy head and thou shalt bruise his heel.†4 The Holy Bible abounds with several verses which teach the way to salvation. In fact the whole Bible, with its old and new testaments, shows â€Å" God's way of having people come to know Him and His plan for mankind, His chosen and special people...who by faith will form the true family of God throughout eternity.†5 God's Thoughts Are Higher Than Our Thoughts Despite the so many verses pertaining to salvation (or maybe due to such great number), even the so-called 'faithfuls' have found themselves in opposite camps. This providence deb ate has been going on for centuries and perhaps, Christians will finally get the correct answer when they come face to face with our loving Lord and Savior Jesus Christ. Our God is a very great God. He is omniscient, omnipresent and omnipotent. He is the first and the last. We may come to know Him, but not yet as fully as we would have wanted. As it is written, â€Å"For my thoughts are not your thoughts, neither are your ways My ways, saith the Lord. For as the heavens are higher than the earth, so are My ways higher than your ways and My thoughts than your thoughts.†6 The Arminians and Calvinists Views A careful and prayerful study of the Holy Bible will reveal chapters and verses which support both the Arminian and Calvinist views. The Arminians View. The Arminians believe that salvation is brought about by the combined efforts of God who initiated the process and man who must respond to God's call. God has provided salvation for everyone, but His provision becomes effecti ve only for those who, of their own free will, 'choose' to cooperate with Him and accept His gracious offer of salvation. Thus man's response becomes the determining factor for the attainment of salvation. At the crucial point, man's will plays a decisive role; in this perspective, man, not God, determines who will be recipients of the gift of salvation.7,8 Arminianism emphasizes conditional election based on God's foreknowledge, man's free will through prevenient grace to cooperate with God in salvation,
