Ethics Utilitarianism Essay

a.) Explain the main differences between the utilitarianism of Bentham and that of Mill. Utilitarianism is an ethical theory that looks at the concept of `utility`, or the usefulness of actions. Two of the most famous Utilitarians were Jeremy Bentham and John Stuart Mill; Bentham was the first to introduce the theory, and his views were more similar to that of Act Utilitarianism. Mill on the other hand differed in his views, and his intention was to improve the theory, and his ideas were closer to that of Rule Utilitarianism; and Mill was also the one to coin the name of the theory. Although it is the same theory, the two philosophers had two different concepts of the best approach to Utilitarianism. One of the main differences between the two philosophers view of utility is their idea of the intrinsic good. For Bentham, the goodness of actions is measured by the amount of pleasure they produce. For him, two things were the most important, the pursuit of pleasure and the absence of p ain, and so happiness is pleasure without pain. Bentham produced his `hedonic calculus` to calculate the amount of pleasure produced by actions, which includes categories such as measuring the intensity, duration, and purity of pleasure to work out the best actions to take. This is because Bentham was a hedonist; he thought the best way to live life is the most pleasurable way. Although he never specifically said himself, it is thought that he would have preferred Act Utilitarianism, which looks at individual acts, and the amount of pleasure they generate, in each situation. This differs from Mill in that he thought the goodness of actions is based on the amount of happiness they produce. The practice of following a rule creates happiness, rather than looking at every separate act; it is thought that he was closer to a Rule Utilitarian, which involves following rules to create greater happiness. Furthermore, Bentham’s Utilitarianism is much more focussed on the individual. The individual judges each act by its utility, and the amount of pleasure it will produce; as it is about the quantity of pleasure, for Bentham, which decides which action should be taken. The motivation is for self-interest, which means that often justice can be ignored, as the focus is not on the wider public, which is different from Mill’s approach. Mill’s approach involves looking at the happiness of the community, so justice is addressed, and well-being has utmost importance. To make it more  universal he said that each desires their own happiness, so they should aim at it, and furthermore everyone ought to aim for the happiness for everyone else too, making sympathy the motive for doing an action. Both approaches are consequentialist, but for Mill, an ethical act is one where the consequences favour the happiness and wellbeing of all. His approach also looks at the quality of the activities as well, arguing that certain things can be rated as `higher` and `lower ` pleasures. He said that food, sex and drink are of the `lower` category, whereas poetry, opera and fine art and the like are of the `higher` pleasures, and that we should strive for pleasure of better quality, of a more high-class lifestyle, as they are of more value. Whereas Bentham uses the example of a game of `push-pin` (a children’s game) gives the same amount of pleasure as a good book, Mill argues against that saying the quality of the pleasure is what is importance. Essentially, what makes an act ethical for Bentham is the amount of pleasure that is produced for the individual, and duration and intensity etc. For J.S. Mill, an act is ethical if it follows more set rules, how much happiness is produced on a larger scale, and the quality of the pleasure, rather than the quantity. b.) `Mill’s Utilitarianism is superior in every way to the Utilitarianism of Bentham`. Discuss. Both Mill and Bentham wished to produce an ethical theory that created the most happiness, which is what they believed to be the basis for justice, and the best way of living. However, since they saw the way to achieve this happiness in different light, they had different approaches to the theory, meaning that one approach will be considered superior to the other. In my opinion, it is true that Mill’s approach is superior to Bentham’s, although not in every way. Firstly, it must be considered that it is not certain which `type` of Utilitarianism each philosopher preferred. Generally it is thought that Bentham took the Act approach, and Mill the Rule approach, however neither put themselves in any of the categories, so it is therefore debatable. It is evident that both do not stick completely to the respective approaches; as an example, Mill was known to write, â€Å"Actions are right in proportion as they tend to promote happiness†, which implies a prefe rence to Act Utilitarianism, although others still think that he may even have been a virtue ethicist. For the sake of this writing though, I will categorise each philosopher to their assumed approach. John Stuart Mill was very familiar  with Jeremy Bentham in person, as he was Bentham’s godson, and it is evident how this relationship affected his view on ethics. Mill attempted to improve Bentham’s theory, this concept of utility, which Mill coined `Utilitarianism`. However, his whole idea of the `greatest good for the greatest number` was accentuated by Mill when he made it more focussed on the community. As he thought more that happiness should be the standard of utility, not the self-centred pleasure. This improves the theory, as otherwise everybody will be focussing on themselves, and in many situations the pleasure of one person may exclude the happiness of many. I think it is also more appropriate inside the theory; as, if one looks out for the community, it seems more likely that the greatest good for the greatest number will be reached. Likewise, Mill’s idea of happiness being about the quality, not the quantity of pleasure, is to an extent better. The higher pleasures taking preference over the lower kinds of pleasures seem to fit with the quality of life, education and so forth. However, there is a danger that this idea quickly becomes snobbish, and puts the higher classes above those who would prefer rap music over opera. I suppose that this could make Mill’s approach `superior`, but in the way that is arrogant and conceited, rather than the definition of superior meaning improved. This shows how the theory is counter-intuitive in some areas; in how the community has importance, and not just the individual; and yet Mill still argues that the quality of pleasure takes precedence over the quantity, which seems to contradict the idea of community, and involve multiple classes. Another negative side of Mill’s theory is that he makes a jump with his universalisability ideas. He makes an inductive leap in saying that just because one person desires their own happiness they will naturally aim for the happiness of everyone else. John Rawls was known for criticising Mill and how it is not ethical to assume that one person would do something for a group, and how people can be used a means to an end because of that. Theoretically it is a suitable idea, that everyone would look out for the happiness for everyone else, but in practice it is not logical, he is separating morality and motive. An alternative approach to Utilitarianism would be that of Henry Sidgwick. In his book `The method of Ethics` he explained how he was concerned with justice in society. Although he was an Act Utilitarian like Bentham, his approach was similar to Mill’s, in that  the consequences take into account the welfare of the people. This is an improvement again on Bentham’s ethics as justice and welfare have importance over the selfish desires of individuals, which supports Mill and his superiority over Bentham’s Utilitarianism. In conclusion, Mill’s Utilitarianism is superior to that of Bentham’s, in that it looks at the welfare of the people more, and even though it is snobbish in some areas where Bentham’s approach is better, overall Mill’s approach is more improved as it looks as the happiness of others.

University of Santo Tomas Faculty of Pharmacy Organic Chemistry Laboratory APPLICATION OF DIFFERENT KINDS OF TEST TO CLASSIFY HYROXY- AND CARBONYL-CONTAINING COMPOUNDS Jane Catherine SP. Villanueva, Edenn Claudine C. Villaraza, Lorenz Oliver C. Villegas and Cristel Bernice T. Wee Group 10 2G-Medical Technology Organic Chemistry Laboratory ABSTRACT Hydroxyl group refers to a functional group containing OH- when it is a substituent in an organic compound. It is also known as the characteristic functional group of alcohols and phenols. On the other hand, carbonyl group refers to a divalent chemical unit consisting of a carbon and an oxygen atom connected by a double bond. It is known as the characteristic functional group of aldehydes and ketones instead. In this experiment, hydroxyl- or carbonyl- containing samples were given to the group for examination. The samples were analyzed through different tests namely the involvement of the solubility of alcohols in water, the Lucas Test, the Chromic Acid Test or also known as Jones Oxidation, the 2,4-Dinitrophenylhydrazone (2,4-DNP) Test, the Fehling’s Test, the Tollens’ Silver Mirror Test, and the Iodoform Test. The solubility of alcohols in water test showed that the sample, benzyl alcohol was immiscible while ethanol was the most miscible from all the other compounds used. While in Lucas Test which was used to differentiated the primary, secondary, and tertiary alcohols had turned tert-butyl alcohol into a cloudy solution afterwards. In Chromic Acid Test which was a test for oxidizable compounds or any compounds that possess reducing property would yield to a blue green solution if it reacted positively. This was seen in all the sample used in this test except for acetone. Whereas Dinitrophenylhydrazone (2,4-DNP) Test was preformed to test for aldehydes and ketones which would result to a yellow orange precipitate if it was positively reacted. All the compounds subjected to this test namely n-butyraldehyde, benzaldehyde and acetone gave a positive result. Fehling’s Test and Tollens’ Silver Mirror Test were used to tests for aldehydes. In Fehling Test, both the n-butyraldehyde and benzaldehyde gave a positive result which was a brick red precipitate but acetone gave a negative result which was only a blue solution. While the Tollens’ Silver Mirror Test had shown that both n-butyraldehyde and benzaldehyde gave a positive result which was a silver mirror and then again acetone gave a negative result which was the absence of a silver mirror. Lastly Iodoform test was performed and was known as a test for methyl carbinol and methyl carbonyl groups. Both acetone and isopropyl alcohol resulted to a positive outcome in this test which was formation of yellow precipitate but n-butyraldehyde on the other hand yield to a negative result which was a yellow solution containing black precipitate. INTRODUCTION In organic chemistry, classification of test was tests that categorize a substance into one of several classes. They were used to detect functional groups and other structural features. Alcohol were derivatives of hydrocarbons in which one or more of the hydrogen atoms have been replaced by a hydroxyl (-OH) functional group. Hydrocarbons are compounds which contain hydrogen (H) and carbon (C) only. The hydroxyl group imparts particular properties to the radical to which it is attached. [1] Figure 1. Alcohol Alcohols are classified into three categories: primary (1 °), secondary (2 °) and tertiary (3 °). This classification is based on the number of carbon-containing groups (R for an alkyl or an aromatic group) attached to the carbon bearing the hydroxyl group. If the carbon bearing the OH has one R group, the molecule is a primary alcohol. If two R groups are attached, it is then a secondary alcohol. If three R groups are attached, then the alcohol is tertiary[1][4] Figure 2. Three alcohol groups There are other molecules that contain an -OH group. Even though water (H2O) contains OH, it is not considered as an alcohol because alcohols were defined as organic compounds that have little or no ionization of the ydrogen. Other organic compounds that contain -OH groups but are not alcohols are phenol (C6H5OH) and acetic acid (CH3COOH). These compounds are not alcohols because they are acidic. The term alcohol, then, is another representation of a type of electronic structure in the molecules of substances. [3] [4] Phenols are aromatic compounds in which a hydroxide group is directly bon ded to an aromatic ring system. They are very weak acids, and like alcohols, form ethers and esters. The main phenols are phenol itself, cresol, resorcinol, pyrogallol, and picric acid. Phenol itself (C6H5OH), also known as carbolic acid, is a white, hygroscopic crystalline solid, isolable from coal tar, but made by acid hydrolysis of cumene hydroperoxide, or by fusion of sodium benzenesulfonate with sodium hydroxide. Formerly used as an antiseptic, phenol has more latterly been used to make bakelite and other resins, plastics, dyes, detergents, and drugs. [4] [15] The hydroxyl- containing compounds used in the experiment were ethanol, n-butyl alcohol, sec-butyl alcohol, tert-butyl alcohol, isopropyl alcohol, and benzyl alcohol. Ethanol also known as ethyl alcohol is a clear, colorless liquid with a characteristic, agreeable odor. In dilute aqueous solution, it has a somewhat sweet flavor, but in more concentrated solutions it has a burning taste. Its low freezing point has made it useful as the fluid in thermometers for temperatures below –40 °C, the freezing point of mercury, and for other low-temperature purposes, such as for antifreeze in automobile radiators. Ethanol is miscible in all proportions with water and with most organic solvents. It is useful as a solvent for many substances and in making perfumes, paints, lacquer, and explosives. 15] Figure 3. Structure of Ethanol n-butyl alcohol also known as n-butanol, 1-Butanol or 1-butyl alcohol is a four carbon straight chain alcohol. It is a volatile, clear liquid with a strong alcoholic odor, and is miscible with water. It is a highly refractive compound which corrodes some plastics, and rubbers. It is miscible with many organic solvents, and incompatible with strong oxidizers. It is also used as a direct solvent and as an intermediate in the manufacture of other organic chemicals. [7] Figure 4. Structure of n-butyl alcohol Sec-butyl alcohol, a four carbon secondary alcohol, is a volatile, clear liquid with a strong alcoholic odor with a water solubility of 12. 5%. This substance is most hazardous when peroxide levels are concentrated by distillation or evaporation. It is a highly refractive compound which corrodes some plastics, and rubbers. It is miscible with many organic solvents, and incompatible with strong oxidizers. It is flammable strongly with a luminous flame. It is used as a direct solvent and as an intermediate in the manufacture of other organic chemicals. [8] Figure 5. Structure of Sec-butyl alcohol Tert-butyl alcohol is a clear, noncorrosive liquid. It is miscible with water as well as most common organic solvents. The sterically hindered tertiary butyl group imparts stability compared to primary and secondary alcohols. As a result, the solubility and oxidative stability characteristics provide many industrial applications as a reaction and process solvent and chemical intermediate. It is used as a non-reactive solvent for chemical reactions, a non-surfactant compatibilizer for many solvent blends, and a non-corrosive solvent. It is used in free radical polymerizations to dissolve monomers. TBA is a main raw material of tert-butyl functional group in organic synthesis. [9] Figure 6. Structure of Tert-butyl alcohol Isopropyl alcohol also known as propan-2-ol, 2-propanol is a common name for a chemical compound with the molecular formula C3H8O. It is a colorless, flammable chemical compound with a strong odor. It is the simplest example of a secondary alcohol, where the alcohol carbon is attached to two other carbons. Being a secondary alcohol, isopropyl alcohol can be oxidized to acetone, which is the corresponding ketone. Isopropyl alcohol dissolves a wide range of non-polar compounds. It is also relatively non-toxic and evaporates quickly. Thus it is used widely as a solvent and as a cleaning fluid, especially for dissolving lipophilic contaminants such as oil. [10] Figure 7. Structure of Isopropyl alcohol Benzyl alcohol (C6H5CH2OH) is a colorless liquid with a mild pleasant aromatic odor. It is a useful solvent due to its polarity, low toxicity, and low vapor pressure. Benzyl alcohol is partially soluble in water (4  g/100  mL) and completely miscible in alcohols and diethyl ether. Like most alcohols, it reacts with carboxylic acids to form esters. Benzyl alcohol is used as a general solvent for inks, paints, lacquers, and epoxy resin coatings. It is also a precursor to a variety of esters, used in the soap, perfume, and flavor industries. It is often added to intravenous medication solutions as a preservative due to its bacteriostatic and antipruritic properties. [15] Figure 8. Structure of Benzyl alcohol Carbonyl group is a divalent chemical unit consisting of a carbon and an oxygen atom connected by a double bond. The group is a constituent of carboxylic acids, esters, anhydrides, acyl halides, amides, and quinones, and it is the characteristic functional group of aldehydes and ketones. Carboxylic acid and their derivatives, aldehydes, ketones, and quinones are also known collectively as carbonyl compounds. Aldehydes and ketones contain carbonyl groups attached to alkyl or aryl groups and a hydrogen atom or both. These groups have little effect on the electron distribution in the carbonyl group; thus, the properties of aldehydes and ketones are determined by the behavior of the carbonyl group. In carboxylic acids and their derivatives, the carbonyl group is attached to one of the halogen atoms or to groups containing atoms such as oxygen, nitrogen, or sulfur. These atoms do affect the carbonyl group, forming a new functional group with distinctive properties. Figure 9. Carbonyl Group An aldehyde is an organic compound containing a terminal carbonyl group. This functional group, called an aldehyde group, consists of a carbon atom bonded to a hydrogen atom with a single covalent bond and an oxygen atom with a double bond. Thus the chemical formula for an aldehyde functional group is -CH=O, and the general formula for an aldehyde is R-CH=O. The aldehyde group is occasionally called the formyl or methanoyl group. The word aldehyde is a combination of parts of the words alcohol and dehydrogenated, because the first aldehyde was prepared by removing two hydrogen atoms (dehydrogenation) from ethanol. Molecules that contain an aldehyde group can be converted to alcohols by the addition of two hydrogen atoms to the central carbon oxygen double bond (reduction). Organic acids are the result of the introduction of one oxygen atom to the carbonyl group (oxidation). Aldehydes are very easy to detect by smell. Some are very fragrant, and others have a smell resembling that of rotten fruit. [15] On the other hand, Ketone features a carbonyl group (C=O) bonded to two other carbon atoms. They differ from aldehydes in that the carbonyl is placed between two carbons rather than at the end of a carbon skeleton. They are also distinct from other functional groups, such as carboxylic acids, esters and amides, which have a carbonyl group bonded to a hetero atom. Ketone compounds have important physiological properties. They are found in several sugars and in compounds for medicinal use, including natural and synthetic steroid hormones. [15] The difference between aldehydes and ketones is in the groups that are attached to the carbonyl carbon atom. In the case of an aldehyde, there is always at least one H atom attached to the carbonyl carbon atom. An aldehyde has one R group attached. R stands for any other organic chain or group. In the case of ketones, there are no H atoms attached to the carbonyl carbon. The ketone has two R groups attached. [2] [15] Figure 10. Structure of Aldehyde and Ketone Some of the carbonyl-containing compounds used in the experiment were benzaldehyde, n-butraldehyde, acetaldehyde, acetone and acetophenone. Benzaldehyde (C6H5CHO) also known as benzenecarbonal is a colorless liquid aldehyde with a characteristic almond odor. It boils at 180 °C, is soluble in ethanol, but is insoluble in water. It is formed by partial oxidation of benzyl alcohol, and on oxidation forms benzoic acid. It is called oil of bitter almond, since it is formed when amygdalin, a glucoside present in the kernels of bitter almonds and in apricot pits, is hydrolyzed, e. . , by crushing the kernels or pits and boiling them in water; glucose and hydrogen cyanide (a poisonous gas) are also formed. It is also prepared by oxidation of toluene or benzyl chloride or by treating benzal chloride with an alkali. Benzaldehyde is used in the preparation of certain aniline dyes and of other products, including perfumes and flavorings. [13] Figure 11. Structu re of Benzaldehyde Acetaldehyde (CH3CHO) also known as ethanol is a colorless liquid aldehyde, sometimes simply called aldehyde. It is soluble in water and ethanol. Acetaldehyde is made commercially by the oxidation of ethylene with a palladium catalyst. It is used as a reducing agent (e. g. , for silvering mirrors), in the manufacture of synthetic resins and dyestuffs, and as a preservative. [11] Figure 12. Structure of Acetaldehyde n-butyraldehyde (CH3(CH2)2CHO) also known as butanal is an aldehyde derivative of butane. It is a colorless flammable liquid that smells like sweaty feet. It is miscible with most organic solvents. n-butyraldehyde is used as an intermediate in the manufacturing plasticizers, alcohols, solvents and polymers. It is also used as an intermediate to make pharmaceuticals, agrochemicals, antioxidants, rubber accelerators, textile auxiliaries, perfumery and flavors. [12] Figure 13. Structure of N-butyraldehyde Acetone ((CH3)2CO) also known as propanone is colorless, mobile, flammable liquid with a characteristic sweetish smell is the simplest example of the ketones. Acetone is miscible with water and serves as an important solvent in its own right, typically as the solvent of choice for cleaning purposes in the laboratory. [6] Figure 14. Structure of Acetone Acetophenone (C6H5C(O)CH3) is the simplest aromatic ketone. This colorless, viscous liquid is a precursor to useful resins and fragrances. It can be obtained by a variety of methods. In industry, acetophenone is recovered as a by-product of the oxidation of ethylbenzene, which mainly gives ethylbenzene hydroperoxide for use in the production of propylene oxide. [5] Figure 15. Structure of Acetophenone The hydroxyl- and carbonyl- containing compounds were analyzed by utilization of different tests such as testing the solubility of alcohols in water, Lucas Test, Chromic Acid Test (Jones Oxidation), 2,4-Dinitrophenylhydrazone Test, Fehling’s Test, Tollens’ Silver Mirror Test, and Iodoform Test. Most organic compounds were not soluble in water with the exception of low molecular-weight amines and oxygen-containing compounds like alcohols, carboxylic acids, aldehydes, and ketones. Low molecular-weight compounds are generally limited to those with fewer than five carbon atoms. [14] Lucas Test often provides classification information for alcohols, as well as a probe for the existence of the hydroxyl group. Substrates that easily give rise to cationic character at the carbon bearing the hydroxyl group undergo this test readily; primary alcohols do not give a positive result. Since the Lucas Test depends on the appearance of the alkyl chloride as a second liquid phase, it is normally applicable only to alcohols that are soluble in the reagent. This limits the test in general to monofunctional alcohols lower than hexyl and certain polyfunctional molecules. [4] Chromic Acid Test also called Jones Oxidation detects the presence of a hydroxyl substituent that is on a carbon bearing at least one hydrogen, and therefore oxidizable. It is detected by the appearance of Cr+3 ion. This test can be used to differentiate aldehydes and ketones. A positive result would show green or blue-green solution. [4] 2,4-Dinitrophenylhydrazone Test can be used to qualitatively detect the carbonyl functionality of a ketone or aldehyde functional group. Ketones and Aldehydes would form yellow to orange precipitate after undergoing in this test. [4] Fehling’s Test and Tollens’ Silver Mirror Test are used to detect aldehydes. However, Fehling's solution can only be used to test for aliphatic aldehydes, whereas Tollens' reagent can be used to test for both aliphatic and aromatic aldehydes. A positive result in Fehling’s Test would give a brick red precipitate while in Tollens' Silver Mirror, it is the formation of silver mirror. [4] Iodoform Test is a test for methyl carbinol and methyl carbonyl group. A positive result would yield to yellow crystals or precipitate. Its mechanism occurs through a series of enolate anions which are iodinated. [4] The objectives of the experiment were to distinguish whether a compound was a hydroxyl- or carbonyl-containing, to differentiate the three types of alcohols, to differentiate aldehydes from ketones and to explain the mechanisms involved in the differentiating tests. EXPERIMENTAL A. Compounds Tested * Ethanol * n-butyl alcohol * Sec-butyl alcohol * Tert-butyl alcohol * Benzyl alcohol * n- butyraldehyde * Benzaldehyde * Acetone * Acetophenone * Isopropyl alcohol * Acetaldehyde * Lucas reagent * Chromic acid reagent * 95% ethanol * Fehling’s A and B * Tollen’s reagent * 5% NaOCl solution * Iodoform test reagent * 2,4-dinitrophenylhydrazine B. Procedure 1. Testing the solubility of alcohols in water The samples involved in the experiment were ethanol, n-butyl alcohol, sec-butyl alcohol, tert-butyl alcohol, and benzyl alcohol. Five test tubes were labeled with each of the alcohol samples. With the aid of a Pasteur pipette, 10 drops from each of the samples were taken then placed into the appropriate test tube. To the tube containing ethanol, 1-ml of water was then added drop wise to the tube containing alcohol and the mixture was shaken thoroughly after each addition. If cloudiness resulted, 0. 25-ml of water at a time was added continuously with vigorous shaking until a homogeneous dispersion results. The total volume of water added was noted. If cloudiness resulted after the addition of 2. -ml of water, the alcohol is said to be immiscible in water but if there was no cloudiness then it is miscible to water. The results were noted down. The same procedure was performed on the test tubes containing n-butyl alcohol, sec-butyl alcohol, tert-butyl alcohol, and benzyl alcohol. 2. Using the Lucas Test This test was performed on n-butyl alcohol, sec-butyl alcohol, tert-butyl alcohol and isopropyl alcohol. Lucas reagent was prepared by dissolving 16 g of anhydrous zinc chloride in 10-ml of concentrated hydrochloric acid. The mixture was then allowed to cool. The Lucas Reagent was already prepared beforehand. 50-mg or 2-3 drops of the sample was added to 1-ml of the reagent in a test tube and the mixture was shaken vigorously for a few seconds. The mixture was allowed to stand at room temperature. The rate of formation of the cloudy suspension or the formation of two layers was observed. 3. Using the Chromic Acid Test / Jones Oxidation This test was performed on n-butyl alcohol, sec-butyl alcohol, tert-butyl alcohol, benzaldehyde and acetone. 1 drop of liquid or a small amount of the solid sample was dissolved in 1-ml of acetone in a small vial or test tube. drops of 10% aqueous Potassium chromate solution and 5 drops of 6M sulphuric acid were added into the mixture. 4. Using the 2,4-DNP Test This test was performed on acetone, n-butyraldehyde and benzaldehyde. The reagent was prepared by slowly adding a solution of 3 g of 2,4-dinitrophenylhydrazine in 15-ml of concentrated sulphuric acid, while stirring to a mixture of 20-ml of water and 70-ml of 95% ethanol. The solution was then stirred and filtered. This reagent was already prepared beforehand. A drop of a liquid sample was placed into a small sample. 5 drops of 95% ethanol was added and well shaken. Afterwards, 3 drops of 2,4-DNP was added and if no yellow or orange precipitate formed, the solution was allowed to stand for at least 15 minutes. 5. Using the Fehling’s Test This test was performed on acetone, n-butyraldehyde, and benzaldehyde. Fehling’s reagent was prepared by mixing equal amounts of Fehling’s A and Fehling’s B. Fehling’s A was prepared by dissolving 7 g of hydrated copper (II) sulfate in 100-ml of water. Fehling’s B was prepared by mixing 35 g of Potassium sodium tartrate and 10 g of Sodium hydroxide in 100-ml water. Then, 1-ml of freshly prepared Fehling’s reagent was placed into each test tube. drops of the sample to be tested was added in to the tube. The tubes were then placed in a beaker of boiling water and changes within 10-15 minutes were observed. 6. Using the Tollens’ Silver Mirror Test This test was performed on benzaldehyde, acetone and n-butyraldehyde. The reagent was prepared by adding 2 drops o f 5% Sodium hydroxide solution to 2-ml of 5% Silver nitrate solution and mixing thoroughly. Next, only enough 2% ammonium hydroxide (concentrated ammonium hydroxide is 28%) was added drop by drop and with stirring to dissolve the precipitate. Adding excess ammonia will cause discrepancies on the result of the test. Then, four test tubes with 1-ml of freshly prepared Tollens’ reagent were prepared. Two drops each of the samples were then added. The mixture was shaken and allowed to stand for 10 minutes. If no reaction has occurred, the test tube was placed in a beaker of warm water (35-50 oC) for 5 minutes. Observations were recorded. It was noted that if Tollens’ reagent is left unused for a period of time, it may form explosive silver. This was avoided by neutralizing unused reagent with a little nitric acid and discarded afterwards. . Using the Iodoform Test This test was performed on acetone, n- butyraldehyde and isopropyl alcohol. 2 drops of each sample was placed into its own small vial or test tube. 20 drops of fresh chlorine bleach (5% Sodium hypochlorite) was slowly added while shaking to each test tube and then, mixed. The formation of a yellow participate was noted. RESULTS AND DISCUSSION 1. Solubi lity of Alcohols in Water In the experiment, five compounds were tested to determine the presence of the –OH, hydroxyl group through solubility of the sample in water. The presence of an –OH group was indicated by the miscibility of the substance. This follows the general rule in solubility that â€Å"like dissolves like†. Meaning, a polar solute will dissolve in a polar solvent and a non polar solute will be insoluble in a polar solvent. [14] Going back to the experiment, it was observed that alcohol was soluble in water but as the number of carbon atoms in the carbon chain of the alcohol increased, the solubility of the alcohol sample decreased. It was also observed that branching of the compound increased its solubility in water. Branching will increase solubility since more branching will reduce the size of the molecule and make it easier to solvate the molecules with the solvent. [14] The results of the experiment show that the solubility of alcohols in water depends on the balance between the strength of the hydrogen bonds formed between water and the hydroxyl group, and the strength of the Van der Waals forces between the hydrocarbon chains of the alcohol. Alcohol| Condensed Structural Formula| Amount of Water (in ml) needed to produce a homogeneous dispersion| Solubility in Water| Ethanol| CH3CH2OH| 0. ml| Most Miscible| n-butyl alcohol| CH3CH2CH2CH2OH| 2. 0 ml| Miscible| Sec-butyl alcohol| | 1. 4 ml| Miscible| Tert-butyl alcohol| | 0. 5 ml| Miscible| Benzyl alcohol| | More than 2. 0 ml| Immiscible| Table 1. Solubility of alcohols in water The table above showed that ethanol, n-butyl alcohol, sec-butyl alcohol, and tert-butyl alcohol were all miscible with water. Only benzyl alcohol had exhibited immisci bility with water. As stated, all alcohols were soluble in water except under C6. Hence, ethanol, n-butyl alcohol, sec-butyl alcohol, and tert-butyl alcohol are all miscible with water. Ethanol has two carbon atoms, while the other three all have four carbons since they are all derivatives of the alcohol, butanol. Benzyl alcohol was immiscible with water because it is an aromatic alcohol. Ethanol was the most miscible alcohol followed by tert-butyl alcohol, sec-butyl alcohol, and n-butyl alcohol. Ethanol exhibited fastest solubility because it has only two carbon atoms as compared to the butanol derivatives having four carbon atoms. Tert-butyl alcohol was the most miscible among the butanol derivatives because it has the most branching substituents present. 2. Lucas Test The four types of alcohols namely n-butyl alcohol, sec-butyl alcohol, tert-butyl alcohol and isopropyl alcohol were differentiated from each other by way of the Lucas Test. Lucas Test differentiates primary, secondary, and tertiary alcohols. Reagents used include anhydrous ZnCl2 and HCl. Positive result was based on its turbidity or alkyl chloride formation and its rate of the reaction. Tertiary alcohols formed the second layer in less than a minute. Secondary alcohols required 5-10 minutes before formation of second layer while primary alcohols were usually unreactive. Substance| Condensed Structural Formula| Reaction| -butyl alcohol| CH3CH2CH2CH2OH| Clear solution(+)| Sec-butyl alcohol| | Clear solution(+)| Tert-butyl alcohol| | Turbid (+++) /Cloudy solution and formation of two layers| IsopropylAlcohol| | ClearSolution(+)| Table 2. Lucas Test Based on Table 2, it was only tert-butyl alcohol which had immediately formed two layers or a cloudy solution; hence, it was known to be a t ertiary alcohol. Sec-butyl alcohol and Isopropyl alcohol when subjected to Lucas test resulted to a clear solution although theoretically, a secondary alcohol dissolves to give a clear solution then form chlorides which would yield to a cloudy solution within five minutes. -butyl alcohol was considered as a primary alcohol. It was unreactive but eventually would react after long period of time. Generally, the order of reactivity of the alcohols toward Lucas reagent was 3 °;2 °;1 ° because the reaction rate was much faster when the carbocation intermediate was more stabilized by a greater number of electron donating alkyl group bonded to the positive carbon atom. This means that the greater the alkyl groups present in a compound, the faster its reaction would be with the Lucas solution. [1] Figure 16. Reaction in Lucas Test 3. Chromic Acid Test (Jones Oxidation) This test was performed on n-butyl alcohol, sec-butyl alcohol, tert-butyl alcohol, benzaldehyde and acetone. The chromic acid test classifies the three types of alcohols by oxidizing the alcohol. The test was also used to be able to distinguish aldehydes from ketones. Since primary and secondary alcohols were also oxidized by the chromic acid reagent, this test was not useful for distinguishing aldehydes unless a positive identification of a carbonyl group has been obtained from the 2,4-DNP test. Chromic acid has an orange-red color due to the presence of Cr+6 ions, upon oxidation of the aldehyde, the chromium was reduced to Cr+3, which had a green color. A positive result was indicated by a green precipitate due to chromous sulfate, Cr? (SO? )?. [1] From the results, it was noted that the formation of an opaque blue-green suspension within 2-3 seconds, accompanied by disappearance of the orange color of the reagent, indicates a primary or secondary alcohol. A primary alcohol oxidizes readily, first to an aldehyde, then to a carboxylic acid. These two oxidation steps made sense because the primary alcohol functional group has two C-H bonds that can be broken; secondary alcohols were oxidized to ketones, a secondary alcohol only has one C-H bond that can be broken, so it can only oxidize once, to a ketone; a tertiary alcohol has no C-H bond that can be broken, so it was not oxidized, no matter how strong the oxidizing agent was. During the oxidation, the orange-red color of the chromic acid changed to a blue-green solution. Figure 17. Oxidation of the three types of Alcohols The results also show that aldehydes gave the same result but reacted more slowly. With aliphatic aldehydes, the solution turned cloudy in about 5 seconds, and the opaque blue-green suspension formed within 30 seconds; aromatic aldehydes required 30-90 seconds or longer before a suspension formed. The generation of some other dark color, particularly with the liquid remaining orange, was considered a negative test. It was concluded that alcohols and aldehydes are oxidized by chromic acid but ketones were not because they don’t have a hydrogen atom attached to their carbonyl group that can be used for oxidation. Figure 18. Oxidation of Aldehyde Substance| Condensed Structural Formula| Reaction| -butyl alcohol| CH3CH2CH2CH2OH| Blue green solution(+)| Sec-butyl alcohol| | Blue green solution(+)| Tert-butyl alcohol| | Blue green solution (+)| n-butyraldehyde| | Blue greenSolution (+)| Benzaldehyde| | Blue green solution(+)| Acetone| | Green solution(-)| Table 3. Reactions to the Chromic Acid Test It was observed that all the compounds tested gave a visible posit ive result, a blue green solution, except for acetone which had yielded to a green solution. 4. 2,4-dinitrophenylhydrazone Test This test was performed on acetone, n-butyraldehyde and benzaldehyde. The 2,4-dinitrophenylhydrazone (2,4-DNP) test determined the presence of a carbonyl group in the sample compound. The test used an organic reactant, 2,4-dinitrophenylhydrazine, to distinguish the carbonyl compounds, aldehydes and ketones, from the non-carbonyl compounds, alcohols. The 2, 4-dinitrophenylhydrazine reagent was a translucent yellow solution. When this reagent was subjected in the presence of a carbonyl compound, a yellow colored precipitate would form while in the presence of an alcohol, the solution would remain translucent yellow with no precipitate formed. The reaction of 2,4-DNP with an aldehyde or ketone was a condensation reaction. Under less acidic conditions, in this type of reaction, a nucleophile donates a pair of electrons toward the carbonyl carbon forming a single bond to it. [2] At the same time the double bond between the carbonyl carbon and oxygen becomes a single bond as one bonding pair of electrons in the double bond moves to become an unshared pair on the oxygen. The oxygen now has one bond to it and it holds three pairs of unshared electrons, so it has a negative charge. Consequently, the oxygen picks up a proton from somewhere and becomes an -OH group. The proton from the acid attaches itself to one of the unshared pairs of electrons on the oxygen. The carbonyl group now has a +1 charge and is very inviting to even a weak nucleophile. So, the nucleophile attacks the carbonyl carbon forming a bond and the doubly bonded oxygen of the carbonyl becomes an -OH, as before. [1] Figure 19. Nucleophilic addition of 2,4-DNP to Acetone. As seen just below, this product is not usually the one that was isolated. Rather this product undergoes an elimination reaction in which the -OH was removed from the carbon to which it is attached and the hydrogen was removed from the nitrogen immediately to the right, resulting in a double bond between the nitrogen and carbon and a molecule of water. The final product was known as a 2,4-dinitrophenylhydrazone. That is why this reaction was also considered as an elimination reaction. Figure 20. Elimination reaction of DNP Figure 21. Reaction of 2,4-DNP with a Carbonyl group Substance| Condensed Structural Formula| Reaction| n-butyraldehyde| | Yellow- orange precipitate(+)| Benzaldehyde| | Yellow –orange precipitate(+)| Acetone| | Yellow –orange precipitate(+)| Table 4. Reactions to the 2,4- DNP Test As shown on table 4, it was observed that there was a formation of a yellow – orange precipitate in all the compounds used. This would then indicate a presence of either an aldehyde or a ketone. 5. Fehling’s Test Fehling's test differentiated aldehydes and ketones. It was based upon the ability of the aldehyde group to reduce the Cu+2 ion of Cu(OH)? , a blue color, to the Cu ion of Cu? O, a dark red color, in the presence of a base. Fehling's solution contains copper (II) ions complex with tartrate ions in sodium hydroxide solution. Complexion of the copper (II) ions with tartrate ions prevents precipitation of copper (II) hydroxide. Aldehydes reduce the complex copper (II) ion to copper (I) oxide, changing the color of the solution to brick red or dark green. Because the solution is alkaline, the aldehyde itself is oxidized to a salt of the corresponding carboxylic acid. [2] In short it involved a redox reaction wherein aldehyde was oxidized to carboxylic acid and ketones did not undergo oxidation. Copper was reduced from Cu2+ to Cu+. Figure 22. Oxidation of aldehyde to carboxylic acid through Fehling’s test It was a test for aldehydes. Reagents include CuSO4, NaOH. A positive result is the formation of brick red precipitate (Cu2O/cuprous oxide). This test was performed on acetone, n-butyraldehyde, and benzaldehyde. Substance| Condensed Structural Formula| Reaction| n-butyraldehyde| | Brick red precipitate (+)| Benzaldehyde| | Brick red precipitate(+)| Acetone| | Clear blue solution(-)| Table 5. Reactions to the Fehling’s Test As shown in Table 5, n-butyraldehyde and benzaldehyde exhibited positive result while acetone exhibited an absence of brick red precipitate. It can be concluded that n-butyraldehyde and benzaldehyde were both aldehyde. 6. Tollens’ Silver Mirror Test Tollens’ silver mirror test was a test for aldehydes. Tollen’s reagent was an ammoniacal solution of silver ion prepared by dissolving silver oxide in ammonia. The preparation of the reagent is based on the formation of a silver diamine complex that is water soluble in basic solution. In this reaction, the aldehyde was oxidized to a carboxylic acid while the Ag+1was reduced to silver metal, which deposited as a thin film on the inner surface of the glass. The generic reaction was as follows and was specific for aldehydes. [16] Figure 23. Oxidation of aldehyde with Tollen’s reagent Substance| Condensed Structural Formula| Reaction| n-butyraldehyde| | Silver Mirror(+)| Benzaldehyde| | Silver Mirror(+)| Acetone| | Clear grayish-black solution (-)| Table 6. Reactions to Tollen’s Silver Mirror Test This test was performed on benzaldehyde, acetone and n-butyraldehyde. Based on the results seen in table 6, it was concluded that the aldehyde samples produced a silver mirror on the inner surface of the test tube since aldehydes were easily oxidized. The ketones sample, acetone, on the other hand, didn’t form this mirror image because of its inability to oxidize due to the lack of a hydrogen atom attached to its carbonyl group that could be used for oxidation. 7. Iodoform Test Iodoform test was a test for methyl carbinol, secondary alcohol with adjacent methyl group, and methyl carbonyl. Methyl ketones, but not other ketones, were oxidized by iodine in aqueous sodium hydroxide. The ketone was oxidized to a carboxylic acid which yellow iodoform/ precipitate would be formed. It was the yellow precipitate formed would be the basis of a positive result. Acetaldehyde, but not other aldehydes, would yield to a positive result in this test owing to its structural similarity to methyl ketones. It was also true that ethanol would be oxidized to acetaldehyde and secondary alcohols that could be oxidized to methyl ketones given this test. [2] Figure 24. Oxidation of a methyl ketone Substance| Condensed Structural Formula| Reaction| N-butraldehyde| | Yellow solution with black precipitate (-)| Acetone| | Yellow precipitate| Isopropyl alcohol| | Yellow precipitate| Table 7. Reaction to the Iodoform Test This test was performed on acetone, n- butyraldehyde and isopropyl alcohol. Based on table 7, the results indicate that the methyl ketones of isopropyl alcohol and acetone were oxidized by iodine to carboxylic acids because the compounds formed a yellow precipitate while n-bytraldehyde didn’t. It was then concluded that compounds with a methyl group next to the carbonyl group would give a positive result in the iodoform test, ethanol and secondary alcohols with the methyl group attached to the same carbon as the OH- group would also give a positive result. During the experiment, the compounds acetaldehyde and acetophenone were not available. This was the reason why results of these compounds in different tests were not observed but based from different informations which were gathered from different sources. Acetophenone would give a positive result in the following test namely 2,4 DNP test and Iodoform test. While acetaldehyde would give a positive result in the following test namely Chromic Acid test, 2,4 DNP test, Fehling’s test and as well as Tollens’ Silver Mirror test.

AFFORDABLE HEALTH CARE Essay Example | Topics and Well Written Essays - 500 words

AFFORDABLE HEALTH CARE - Essay Example Thinking of the possible strategies and reforms to mitigate the problem, I came up with the accurate suggestions and critical thoughts on Medicare, which I would share within the following reflection. As it has been mentioned in the case, the Rosalyns preexisting condition of ulcer restrained her from receiving due to the few compounding circumstances: first, she was divorced, second, her annual salary at the gift-wrapping company of $19,000 was insufficient to cover medical care and the employee did not provided any sort of medical coverage for her, the last, but not the least, a â€Å"relatively innocent† disorder, an ulcer, made so far expensive medical insurance to cost like a sort of luxury. Obviously, if Rosalyn was not rejected at first, her cancer would not metastasized into womans hips and she would not break her fragile hip bone. The woman died a decade after her surgeries. In the aftermath of Rosalyns case, it may seem that costly medical advantages seem to be a kind of unattainable service even for those, who are, like, Rosalyn, in desperate need for emergent medical assistance. It is impossibly cruel to make someone suffer, witness how their health state progressively deteriorate. What make things feel even worse, is that getting sick for average middle-aged employed American citizen is a sort of fatal disaster. Rosalyns case seems to be outrageous, if observed through the lens of distributive justice theory. That concept is related to the fair distribution of existent resources amidst diverse members of the society. That justice is grounded on the total amount of goods to be allocated, the procedure and distributive pattern. In the health care settings, like in any other field, distributive justice is expected to work for the good of patients. Allocation of medical services, thereof, should be based on the criteria of need, equity and equality. Currently, the United States of America maintains a patchwork system of five

Technology and Productivity in the Workplace Essay

Technology and Productivity in the Workplace - Essay Example At this particular stage in the IT revolution, many organizations This reverse effect of technology is attributed to two problems that have cropped up on the use of Information and Communication Technology (ICT) tools: segmentation and loss of context. The reason why segmentation and loss of context complicate rather than facilitate problem solving in the workplace is that information made readily available by technology is segmented into pieces such that its recipients are forced to locate the place of each piece in the puzzle. When these segments or units of information reached the recipient, they are often stripped of their meaningful context or original situation of use (Risku & Picher online). The result is occasional stress and frustration in the workplace, which are effective deterrents to productivity. This paper delves into the reasons why technology falls short of its high expectations in the workplace, how the man may have been relegated to a backseat in favor of the machine, and what can be done for the workplace to exact the promised benefits from technology. The central issu Case against Technology The central issue boils down to a conflict between creativity and control on one hand and economic viability on the other. In the words of Storck (2001), the issue of whether computers are a help or hindrance can be reduced to the question: Does it prevent or promote higher productivity Technology is a great help if it lifted the per capita productivity of workers, but it is a hindrance if ICT systems in fact contributed to a decline in productivity at the workplace. Technology through revolutionary transportation and communication systems toppled down international borders and gave way to the Global Village, a business and economic phenomenon. But this is the bigger picture. In the actual workplace, technology users are expending time and energy grappling with newfangled tools that had minds of their own. IT tools were devised to make performance of tasks easier and faster, bridging any distances so that all participants access the same knowledge. But this technology works best for business organizations if it can be integrated into accepted ways of organizational behavior and it does not interfere with man's desire for belonging and professional stability (Risku & Picher online). The Embedded Cognition Theory set by Suchman (1997) suggests that knowledge provided by IT systems fails to raise productivity and promote intelligent problem solving in the workplace because it prevents man's cognitive urges to tackle new challenges and to interact with fellow humans. Based on the collective intelligence and organizational knowledge theories (Levy, 1997 and Spender, 1996, respectively, as cited in Risku & Pricher), a worker is smarter and more intelligent if his mind, body and environment interact in a dynamic manner. The closer this interaction is,

Violence Against Women And Girls Research Paper

Violence Against Women And Girls - Research Paper Example Modern societies are still learning to know how to treat the modern sophisticated woman who is financially independent and also academically competitive. Even though these women are financially and economically as well as intellectually competitive at the same level with men, they still face a lot of issues which limit how much they can achieve in their societies. One of the most obvious results of women sexualization issues and how it is related to gender violence is the way in which women are treated in most Islamic societies. In Saudi Arabia, women are prohibited by law from participating in such activities which are only thought to be meant for men, such as driving an automobile. This is an issue which has led to a lot of controversy in the world. In the year 2013, women in Saudi Arabia demonstrated against a law passed prohibiting them from driving. In Indonesia, women demonstrated in the streets while wearing short skirts in the demonstration of the increasing rape cases in Ind onesia. In the east, women are forced to wear very heavily so that they hide her femininity while in the west social pressures may force a woman to wear revealing clothes because they are judged by how they look. Gender violence has remained to be a major challenge of the 21st century, mainly because it is supported by many traditions and attitudes in many societies. To be able to deal with this gender violence, it will be necessary to overcome these barriers and make sure that women are viewed in a different way.

The Users Experience of Critical Situations or Metal Psychiatric Medi Essay

The Users Experience of Critical Situations or Metal Psychiatric Medical Emergencies - Essay Example This is not quite in line with the NICE guidelines which suggest that mental health services should be provided for patients diagnosed with debilitating mental disorders that ensures that patients, and their families and carers, are well informed, cared for and supported (Nice.org.uk) There are several case studies in the literature with respect to critical situations or metal psychiatric medical emergencies. The perspective of users of the healthcare facility offered by the healthcare services is vital to gain a proper understanding of the situation. The other important aspect is the perception of palliative care and requirements of a patient suffering from a medical crisis. With respect to modern medicine, the French philosopher Descartes’s writings in the 17th century have had a very deep impact on the management of symptoms by healthcare professionals and their ways of approaching symptoms. This hence is reflected in both our perceptual understanding of them and consequently how we attempt to manage them. As mentioned earlier the principal outlook based on the philosophies of Cartesian dualism is that symptoms should be understood as aspects of a disordered biological state. The resultant trend is reflected in modern medicines approach to care which has largely been based on differentiating between physical and non-physical aspects of disease symptoms and subsequently targeting care at these physiological manifestations. However, most patients seldom if at all distinguish between the biological and perceptual symptoms, and indeed effective and appropriate acknowledgement of personal meanings of illness and its problems is a primary step to effe ctive care of sick individuals and their families ( Wenger, 1993; Halldorsdottir & Hamrin, 1996). Illness, as Pellegrino (1982) defines it, is only partially defined when understood as a physiological anomaly. The experience of sickness in psychiatric/behavioural dysfunction holistically is formed by an individual's acuity of alterations in his/her existential state and should not be ignored.

The behaviors led to the closure of the company as a manager did not take considerable measures on his employees. HRIS system tracks down and records accurate information about an employee, which can cause overload, as a result, a company cannot handle payroll in-house as it is time consuming, which negatively affects the performance to the employee. An organization may hire a third party to handle payroll on company’s behalf and improve employees performance (Ray and Rajesh 286). An automated payroll ascertains that the company manages its payroll processes more effectively. It may be a difficult task for an expanding organization to keep track of the payroll by hand. The system ensures the company’s compliance with state regulations and laws as it automatically deducts services such as, taxes and insurance benefits, which secure the employees (Ray and Rajesh

A COMPARISON OF AN AUTHENTIC TEXT WITH A PEDAGOGIC TEXT Essay

A COMPARISON OF AN AUTHENTIC TEXT WITH A PEDAGOGIC TEXT - Essay Example Authentic texts are defined as a text made to realize a social function within the language community. Pedagogic texts such as text dialogues like those found in English as a Foreign Language teaching materials differ largely from authentic texts across a variety of discourse features (Stubbs 2009) and (Widdowson 2008). These features include turn-taking and length patterns, the number of repetitions and false starts, lexical density, pausing, terminal latching or overlap frequency as well as usage of back-channelling and hesitation devices. This paper will compare and contrast an actual dialogue with a text book dialogue using a hotel booking telephone dialogue as an illustration. Conversations’ length Generally, an authentic telephone conversation on hotel booking would be longer than a telephone dialogue in a textbook (See Appedix 1 and 2). This can be explained by the fact that the turns taken by the information givers are virtually twice lengthy as those undertaken by the information receivers (Carter 2008) and (Sacks, Schegloff & Jefferson 2010). Authentic telephone dialogues would have a more intricate arrangement, with the straightforward question-answer pattern interrupted by several factors (McCarthy & Carter 2004). For example, problems arise in ‘Booking a hotel by phone’, there are unavailable rooms on ground floor, plus on top of that a discussion concerning elevators as well as standard rooms versus executive rooms may arise (Cunningham & Moore 2005). Further information is regularly entreated by the giver of information. For instance, in a conversation ‘concerning hotel booking’, the assistant may enquire whether the client would prefer a room with twin beds or single beds. Answers to queries are longer within authentic texts, where the information giver offers more than one option (Stubbs 2009) (Widdowson 2008). For instance, in ‘hotel booking’ the receptionist may suggest a room with an ocean view. Clearly, real-life is not as straightforward and simple as compared to dialogues found in text books. Text book dialogues are precise since they cannot capture a real-life scenario and perhaps because the text books writers’ tend to present them that way (Carter & McCarthy 2007) and (Myers-Scotton & Bernstein 2008). Unlike in real dialogues, the language of text book dialogues represents a ‘can do’ community where interaction is generally problem-free and smooth (See appendix 2). The speakers collaborate with one another courteously; the dialogue is neat, predictable and tidy. The queries and responses sequenced somewhat in the style of a court-room interrogation or quiz show (Cunningham & Moore 2005). This is, certainly, intentional and is executed for several reasons. Principally, if the core objective of text book dialogue is to exhibit novel functional and structural language through text simplification, this enables learners to focus upon target language exh ibited, to spot it, as well as hopefully obtain the structures rapidly accordingly (Carter 2008). Another reason for text simplification is to render comprehension tasks simpler. If a dialogue runs along expected lines, in which the author expect the learner to be aware of what may be uttered next as well as utilize top-down procedure to decrypt the message (Carter & McCarthy 2007), (Stubbs 2009) and (Widdowson 2008). The more random a dialogue is, the more acquirers have to depend upon ‘bottom up’ processing, for instance, taking note of individual words as well as developing them up to reach at the implication (Sacks, Schegloff & Jefferson 2010). Nevertheless, if the dialogues are only made predictable, learners may be denied the chance to build up their ‘

The Discovery Essay Example for Free

The Discovery Essay ‘The Discovery’, by J. C Squire describes a historical event: Christopher Columbus’s ‘discovery’ of the New World on his 1942 expedition across the Atlantic Ocean which initiated the process of Spanish colonisation. The poem has gone by several names including ‘The Caravels, ‘Sonnet’ and ‘There was an Indian’. John Collings Squire (J. C Squire) (1884-1958) was a British poet, writer, historian, influential literary critic and editor of the post WW1 period. He was also a leading poet of the Georgian period. The poem is a simple sonnet; made up of two quatrains and a sestet. The rhyme scheme is abab, cdcd, efegfg. The rhyme creates a steady, forward-moving motion similar to the movement of the waves and the inevitability of the oncoming Spanish vessels reaching the shore. The poet uses simple language and imagery which mirror the uncomplicated life of the Indian from whose perspective this historical event is retold. The discovery of the New World is often related from the perspective of the Spanish colonisers of the 15th and 16th centuries. Squire also reminds us that this was a two-fold discovery as the indigenous Americans discovered a new world of their own. The phrase, ‘an Indian’, in the first stanza lends a sense of anonymity to the identity of the Indian who witnesses the arrival of Columbus. The indefinite article (an) allows us to believe that this Indian represents all Native Americans. The opening line is reminiscent of a folktale. This style suggests a mythologizing of this historical event, infusing it with an element of magic. One might also believe it to be an example of the oral tradition of legends told among Native Americans. Like other Indians, the Indian in the poem ‘had known no change’. His life consisted of gathering shells; a simple way of life that belonged to an old civilisation for which this discovery was sure to be a shock. The alliteration of ‘s/sh’ in the line ‘†¦ along a sunlit beach. Gathering shells’ depicts the calm, serene and uninterrupted life of the natives. He ‘strayed content’ almost aimlessly, along a ‘sunlit beach’, in no rush to go about his simple life. The presence of dawn symbolises the dawn of a new era in the life of the Indian. We are reminded that historical records show that the event occurred at dawn. Light also symbolises knowledge and discovery for both the Spanish and the Indians. The caesura in the third line ‘He heard a sudden, strange commingled noise’ effectively draws our attention to the abrupt change in this tranquil picture. The caesura evokes a sense of confusion in the atmosphere which was once silent but is now filled with an unfamiliar noise. This is created through the use of alliteration and hard consonants. The Indian’s reaction in the last line of the first stanza ‘looked up: and gasped for speech’ indicates how amazed and speechless he was. The caesura in line four ‘Commingled noise: looked up; and gasped for speech’, also denotes the abrupt actions and reactions of the Indian man. The second stanza is linked to the first stanza by means of a further explanation for the sudden change in the first quatrain. The poet evokes the Indian’s tone of amazement and wonder at the appearance of the ‘huge canoes’ that appear ‘by magic’. The idea of magic evokes a contrast between the two civilisations; the superstitious, tribal beliefs of the natives versus the more advanced scientific beliefs of the Spanish. The poet also evokes the serene, tranquil and undefiled setting and one of confusion which is emphasised by the impressive image of these unnatural and unfamiliar sea vessels on the water. The Indian is unfamiliar with these large ships. In fact, he can only describe them in terms of what he already knows, for eg. ‘huge canoes’ and ‘not one oar’. The Indian’s tone of awe is audible even though the poet does not give him a voice. Perhaps, this is to further emphasise the domination and oppression of the Spanish colonisation of the Native Americans stamping out their voice, culture and traditions. The images used in the stanza are simple yet vivid as can be seen through the image of the ‘Bellying cloths’ and ‘Fluttering coloured signs. The second quatrain is stylistically interesting because the poet is conscious of the different perspectives: that of the Indian man who tries to describe these unfamiliar objects by adapting them to those he is familiar with, and that of the reader who has a knowledge of history and immediately recognises the Indian’s attempt to describe the billowing sails, fluttering flags and ‘clambering crews’. The alliteration of the letter ‘k’ sound in the last line of the second stanza ‘And fluttering coloured signs and clambering crews’, reminds us of the confusion and cacophony created by the sailors as they prepare to land. The third stanza, the ‘sestet’, begins with the conjunction ‘And’, linking it to the previous stanzas. There is now a Volta as the focus shifts to the Indian’s reaction to the caravels. There is an even greater use of caesura which creates an abrupt and staccato rhythm which might reflect the fear that has overcome the Indian, maybe his accelerated heartbeat too. The Volta between the second and third stanzas is also evident in the rhyme scheme which suggests the inevitable, impending conclusion to this sighting as the caravels ‘Slant to the shore, and all their seamen land’. The final stanza draws a clear contrast between the native, who is ‘naked’ and ‘alone’ and the numerous sailors disembarking ‘Columbus’ doom-burdened caravels’. The Indian’s nakedness suggests his primitive lifestyle and his defencelessness. The Indian reacts ‘in fear’ and drops his shells. This symbolises the fall of the native civilisation; his face turns white and he also kneels behind a stone. He stares at this monstrous sight and ‘did not understand’ the full impact of what was unfolding before his eyes. The poet’s intention is to make the contrast between the Spanish and the Indian evidently clear and simple to the reader, in order to draw our attention to the other side of the story which is rarely told in history books. This is emphasised by the choice of perspective for the poem. The image of ‘Columbus’ doom-burdened caravels’ is a powerful one, suggesting a grimly mocking or cynical tone because these caravels symbolise the beginning of the corruption of old civilisations. The final image of the sailors landing on shore is ominous, adding to the heaviness that weighs upon the reader’s knowledge of what will inevitably follow. The poem ends abruptly as the poet does not need to tell us anything else due to the readers’ knowledge of what happens next which has been documented in the history books.

Corporate Social Responsibility in Banking

Corporate Social Responsibility in Banking Abstract: In todays global economy, corporate social responsibility (CSR) is a core component of corporate strategy. As a result CSR emerge as a safeguard to protect financial scandals and diminish reputation of the banks. It also advocates and works to minimize the conflicts with stakeholders. Corporate Social Responsibility (CSR) designed to respond to huge unmet needs of the society in the achievement of long term and persistent business value. Especially commercial banks play an important role in implementing various social and philanthropic programs to help disadvantaged people of the country. To reinforce, CSR activities, banks have focused the area of market place, work place, community and environmental policy. The analysis in the study was targeted to understand the overall corporate responsibility status in the banking sector of Bangladesh. Keywords: Corporate Social Responsibility, Commercial Banks, Bangladesh. Introduction: Now-a-days corporate strategy planner focuses their concentration on wealth maximization rather than profit maximization. The main cause is the intense market competition. So, they divert mentality from conventional business to social business. In addition, recent financial scandals eg, Enron, Parmalat, Worldcom etc have forced corporate executives, globally, to contemplate a broader strategy beyond the focused view of stockholders wealth maximization. The impact of business on the society has become a crucial issue. As a result, banks are emphasized on social, ethical and environmentally responsible approaches to business activity. Bank examine the environmental effect of projects in loan approval process and no projects are approved which are detrimental to the environment. Commercial banks are well aligned with Bangladesh Banks guidance on this aspect. They believe in the need to focus on poverty alleviation through education and health care, for long run benefit of the nation. Recent theories of CSR (Baron (2001), McWilliams and Siegel (2001), Bagnoli and Watts (2003)) assert that firms engage in profit-maximizing CSR. That is, companies are assumed to be socially responsible because they anticipate a benefit from these actions. The World Business Council for Sustainable Development (WBCSD) has given the following definition of CSR: CSR is the task of a business to contribute to sustainable economic development, working together with workers, their families, the local community and society in general to improve quality of life. Barnea and Rubin (2005) demonstrate that the decision to invest in CSR is negatively related to insider ownership, and interpret this finding in the light of an overinvestment hypothesis. CSR is good for shareholder value, up to a given level, but insiders may have an interest to overinvest in it to improve their reputation, and they are more likely to do so when their ownership share is lower. Literature Review: There is a growing trend for investors to direct their money towards explicitly socially responsible organizations. According to Peter A. Heslin and Jenna D. Ochoa (2008) The amount invested in green mutual funds in the U.S. rose 695% in the last six years. During the last three years, the amount of money invested in clean energy has reached U.S. $70.9 billion globally. The primary goal of any economy is to maximize the material wealth of nations (Adam Smith), production and distribution of wealth (John Stuart Mill), to maximize material wealth and material welfare (Alfred Marshall), satisfaction of the human needs with the scarce means (Lionel Robbins). But now a day, the objective of a firm is not only consistent with those scholars but also incorporates social, ethical and environmental concerns. Therefore the primary objective, the purpose or use for which, firms exist is to ensure the subsistence of mankind and sustenance of the Earth containing the mankind. Some authors have argued that the stakeholder perspective of CSR ought to extend to the concept of accountability. Drawing from the works of other academics (e.g. Gray et al. 1987; Williams 1987; Roberts and Scapens, 1985), Swift (2001:17) broadly describes accountability as the requirement or duty to provide an account or justification for oneÊÂ ¹s actions to whomever one is answerable and narrowly as being pertinent to contractual arrangements only, where accountability is not contractually bound there can be no act of accountability. According to Lantos (2001), ethical CSR is a firms mandatory fulfillment of economic, legal and ethical responsibilities. It is akin to the first three components of Carrolls typology. Altruistic CSR is the same as philanthropic responsibility of Carrolls typology but differed from it in the sense that Lantos argued that it would only be possible for private firms to be philanthropic and irresponsibility on the part of public corporations since they do not have the rights to use the funds of shareholders (who might also be involved in private philanthropy) for public philanthropy. As argued by Konz and Ryan (1999: 200): People are searching for meaning in work that transcends mere economic exchanges between isolated, autonomous individuals. (and) a way to connect their work lives with their spiritual lives, to work together in community, to be unified in a vision and purpose that goes far beyond making money. In modern era, business activities moving around the society visualizing sustainable development. It is not only a promotional activity but also an ethical dilemma. Some of the authors findings are given below: Author Findings Sethi (1975) corporate activities should be stable over time definitions of various categories should be applicable across firms, industries, or even social systems, making comparative analysis possible. Carroll (1991, 2004) CSR is made up of the following components in a bottom-up order: (1) economic responsibility be profitable (2) legal responsibility obey the law (3) ethical responsibility be ethical (4) philanthropic responsibility -be a good global corporate citizen Lantos (2001) Identified the following strands of CSR: (a) ethical CSR, (b) altruistic CSR and (c) strategic CSR CPD (December, 2002) Following issues have been identified under corporate responsibility framework:- Sustainable Development Business Ethics Human Rights Legal Compliance Corporate Governance Fair Employment Health Safety Labor Standards Community Relations Environmental Responsibilities Objectives of the Study: The objective of the study is to investigate a definite structure and concept of Corporate Social Responsibility (CSR) in the area of banking sector. It deals with early history of corporate social responsibility, banking mission, and the area of social welfare. Besides these, it has some special objectives. These are: To get an idea of banking role in sustainable development. Evaluate transparency and accountability of corporate as well as public entities. To learn business ethics, safety and ergonomic issues. To learn banks responsibility to community. To know standard conduct that includes employment fair policy and all core labor standards. Methodology of the study: The paper is constructed to synchronize theoretical and practical exposure of CSR in Banking perspective. As a result, the paper is descriptive in nature. Most of the information are generated by evaluating Secondary Sources like: Annual report of different commercial Banks Study related books and journals Web sites Collected data have then processed compiled with the aid of MS Word, Excel other related computer software. Necessary tables have been prepared on the basis of collected data and various statistical techniques have been applied to analyses on the basis of classified information. Evaluation and Findings: In Bangladesh, there are forty eight scheduled banks and out of them forty six had engagement in CSR practices in some form or other in 2009 (Review of CSR Initiative-2008-09). Due to intense competition in the banking sector, it is essential for a bank to behave in a responsible manner towards the society. This sense stimulates business activities in a long term and persistent social value. To attain this intrinsic quality banks should: Focus on vision based strategy (wealth maximization rather than profit maximization). Draw their attention to internal and external components of the CSR activities like; fair salary structure, employee benefit, corporate governance, labor standards etc. They need to trust their shareholder-customers, shareholders, employees and society. Behaving responsibility towards society and the environment strengthens this trust. Their commitment has always been to behave ethically and to contribute towards changing the quality of life of their people, the local community and generally the society. Corporate social responsibility focuses on: Figure 3.2: Area of Social Responsibility Work Place Environment Market Place Area of CSR Community Source: Annual Report of National Bank Ltd (2009) In 2004 and 2005, several banks adopted meticulous CSR policies to limit lending related to destructive projects. The intense pressure from environmental activists and shareholders, different banks agreed to not finance projects in endangered or high conservation value forests or where illegal logging is occurring. Environmental concerns have grown steady during the past several decades. Goldman Sachs was the first global investment bank to adopt a comprehensive environmental policy. The natural environment is the major worldwide issue facing the business and the public. World concern continues to mount about the depletion of the Earths ozone layer and the resulting green house effect, a dangerous warning of the Earth. In the year 2007, There is a greater concentration in the field of disaster relief, both in participation and expenditure wise, was observed mainly because of the cyclone Sidr. Whereas, in the year 2009, the Education and Health sectors were getting more attention and appeared to be the most popular area for CSR activities as huge investments are being made by several banks in these segments. These shifts point to the responsiveness of the banking community to the changing need of the society. Despite progress made by many companies, adoption of CSR policies and reporting are still in its early stages at most corporations. Our Corporate Social Responsibility Program engages companies to adopt strong social and environmental policies, and follows us to ensure that commitments are kept. Corporate social responsibilities may provide added advantages to the business like as Balanced Score Card. Because pushing incentives in the base level (Work Place, Market Place, Community and Environment) will increase bottom line figure (Profit) of the statement. The positive attitude towards the focused element (Table-03) is the way of getting added advantages from the society. Major Areas Focused Element Added Advantages Work Place Working Environment Enhance employee satisfaction, confidence, productivity and loyalty Employee Benefit Training Job Security Gender Discrimination Staff welfare Day-care Center for children of bank employee Market Place Customer Service Attain customer fidelity, and retention New Product Introduce new technology Community Education Secure public confidence, interaction, positive attitude and devotion Employment Sports Cultural Activities Health Care Disaster Relief Environment Forestation Allure public attention through ethical behavior Financing on eco-friendly firm (Financial Inclusion) Fig: Added Advantages received by practicing CSR The Financial sector in turn can contribute hugely by catalyzing CSR practices in their real sector corporate clients, promoting inclusive economic and social development. In terms of direct monetary expenditure, engagements of banks in CSR initiatives are increasing, particularly following issuance of BB guidance (DOS Circular No 01 Dated 1st June 2008): CSR expenditures of banks have thus far largely been in the form of passive grants and donations. Apart from one-off grants and giveaways, some banks have engagements in longer term continuing support commitments, in areas of education and healthcare. Besides the passive engagements by way of grants/donations (Table 1, Section B, page 2), banks are now getting actively engaged in socially responsible business operations, by way of increased lending to under-served economic sectors like agriculture and SMEs, towards fuller financial inclusion and faster poverty eradication. The June 2008 BB Guidance circular suggested that banks could begin reporting their CSR initiatives in a modest way as supplements to usual annual financial reports, eventually to develop into full blown comprehensive reports in GRI format. Banks are yet to adopt separate reporting of their CSR activities in comprehensive formats such as the GRI format. Recommendations: The ultimate conclusion is that corporate responsibility is a changing philosophy of business. The demands for social responsibility have provoked enthusiastic discussion and debate on what new roles, if any, business firms should play in the social system. Banks should not attempt to minimize the expectations of the society; rather they need to respond to them more efficiently. The corporate responsibility practices can play positive role in improving competitiveness in the corporate entities in Bangladesh as well as improve working and living environment for the workforce. Whether is for the government, the community, shareholders, directs, top management, employees or the general public, a corporate organization that intends to effect changes in the environment must always perform a number of socially responsible actions. Formulate uniform rules and regulations: Government or regulatory bodies should formulate uniform rules and regulation regarding CSR practices in banking sector. Tax Shield: All social contribution by the banks should be tax exempted. As a result, social contribution will increase gradually. Change corporate values: In most of the cases, social contribution treated as enhance reputation only. But, they have to change their values and try to think its their responsibility too. Improving Business and Social Productivity: A societys productivity depends on how efficiently it uses resources. If the naturally human and financial resources are combined and managed effectively by business forms then the productivity of both business and society can be high. Balancing Ethics and Economics:A serious social challenge to business is to integrate ethics and economics. How much more profit is desirable and what cost to the customers? What about product quality? Is the customer being cheated through poor measurement or abrasive advertisement? Ethical behavior and economics are the opposite sides of a bad coin. There should be a balance. References: Carroll, A. B. (1991). The pyramid of corporate social responsibility: Toward the moral management of organizational stakeholders.

Biography of Franklin Delano Roosevelt Essay -- FDR American President

Biography of Franklin Delano Roosevelt Franklin Delano Roosevelt, (1882-1945), 32nd of the United States. Roosevelt became president in March 1933 at the depth of the Great Depression, was reelected for an unprecedented three more terms, and died in office in April 1945, less than a month before the surrender of Germany in World War II. Despite an attack of poliomyelitis, which paralyzed his legs in 1921, he was a charismatic optimist whose confidence helped sustain the American people during the strains of economic crisis and world war. He was one of America's most controversial leaders. Conservatives claimed that he undermined states' rights and individual liberty. Though Roosevelt labored hard to end the Depression, he had limited success. It was not until 1939 and 1940, with the onset of heavy defense spending before World War II, that prosperity returned. Roosevelt also displayed limitations in his handling of foreign policy. In the 1930's he was slow to warn against the menace of fascism, and during the war he relied too heavily on his charm and personality in the conduct of diplomacy. Still, Roosevelt's historical reputation is deservedly high. In attacking the Great Depression he did much to develop a partial welfare state in the United States and to make the federal government an agent of social and economic reform. His administration indirectly encouraged the rise of organized labor and greatly invigorated the . His foreign policies, while occasionally devious, were shrewd enough to sustain domestic unity and the allied coalition in World War II. Roosevelt was a president of stature. The future president was born on Jan. 30, 1882, at the family estate in Hyde Park, N.Y. His father, James (1828-1900), was descended from Nicholas Roosevelt, whose father had emigrated from Holland to New Amsterdam in the 1640's. One of Nicholas' two sons, Johannes, fathered the line that ultimately produced President Theodore Roosevelt. The other son, Jacobus, was James' great-great-grandfather. James graduated from Union College (1847) and Harvard Law School, married, had a son, and took over his family's extensive holdings in coal and transportation. Despite substantial losses in speculative ventures, he remained wealthy enough to journey by private railroad car, to live graciously on his Hudson River estate at Hyde Park, and to travel extensively. Four yea... ...nd front greatly intensified Soviet suspicions of the West. But it is easy to second-guess and to exaggerate Roosevelt's failings as a military leader. The president neither invited nor welcomed the Pearl Harbor attack, which was a brilliantly planned maneuver by Japan. He worked with Darlan in the hope of preventing unnecessary loss of Allied lives. Unconditional surrender, given American anger at the enemy, was a politically logical policy. It also proved reassuring to the Soviet Union, which had feared a separate German-American peace. Establishing the second front required control of the air and large supplies of landing craft, and these were not assured until 1944. In many of these decisions Roosevelt acted in characteristically pragmatic fashion--to win the war as effectively as possible and to keep the wartime alliance together. In these aims he was successful. By 1945, Roosevelt was 63 years old. The events early in that year added to the strains on his heart, and on April 12, 1945, he died suddenly at Warm Springs, Ga. Three days later he was buried at Hyde Park. Despite his limitations, he had been a strong, decent, and highly popular president for more than 12 years.

Computers, the Internet, and the World of Education :: Technology Education Educational Essays

Computers, the Internet, and the World of Education Computers and the internet have changed the world of education in innumerable ways. This means the teacher must also change. Most students now have access to countless sources of information from all over the world. They can also talk to experts in multitudes of professions. Many students now learn to type before they learn to write in cursive. Despite these facts not all the changes have been positive. Students are now exposed to outside predators who may try to take advantage of them. In addition they may be exposed to obscene materials. Schools have installed filters, but they sometimes are unable to prevent all inappropriate material from being viewed. Many teachers complain that the internet allows plagiarism and all out cheating with access to pre-made term and research papers (where do you think this paper came from). Many critics of the educational system also point out that often students only like to use computers to access information. They don’t like to use compute rs for their many other uses like complicated math problems or construction of spreadsheets. Unfortunately, this seems to be true computers need to be used across the curriculum not just for research projects. Yet another benefit having computers and internet access in the classroom is the ability of students to be able to talk to experts in their respective fields. Children doing a project on insects can to talk to scientists who work with insects every day. They may be lucky enough to talk to an astronaut or maybe an author whose books they have been reading. Children can also participate in interactive chat rooms with other students or international pen pals. With this said it’s important that teachers take the proper precautions. Everyone knows that the internet poses many dangers especially for unsupervised children. When children are using chat rooms, care needs to be taken to ensure the children safety. Any student using a chat room needs to have a screen name(www.ptft.merit.edu). Teachers have to make sure they go over certain rules before they allow any student use the internet. Students must be taught to never give personal information over the internet this includes their name, location, or telephone number. It can be quite a liability to have internet access in the classroom; teachers must be sure they protect themselves. Another worry is that students may access inappropriate material.

One Flew Over The Cuckoos Nest :: essays research papers

"Ting. Tingle, tingle, tremble toes, she’s a good fisherman, catches hens, puts ‘em inna pens†¦wire blier, limber lock, three geese inna flock†¦one flew east, one flew west, on flew over the cuckoo’s nest†¦O-U-T spells out†¦goose swoops down and plucks you out."The book "One Flew Over the Cuckoo’s Nest" is about a man, Randle Patrick Mc Murphy who is a rough-and-tumble, fun-loving guy who comes into the mental ward in Oregon and challenges the authoritarian nurse, Ms. Ratched. As the struggle between them goes on, Mc Murphy starts to show the other men of the ward how to loosen up and that they do not have to always listen to the nurse. Eventually, Mc Murphy is defeated when Ms. Ratched makes him get a lobotomy. When you first pick up the book, you will first notice that the story is told by one of the men who live in the ward. This is Chief Bromden; a half-Indian who is one of the long time committed men. In my eyes, the Bromden is a key character in the whole book. The Chief, in reality, is 6 foot 7 inches tall, but in his mind he sees himself as a man only two or three feet tall. This is because he has received over 200 electro-shock treatments and has been physiologically beaten to think that he is an inferior being to all others but he is not alone. All of the patients in the ward have had this done to them, some more than others. Another thing that sets the Chief apart is the fact that he has led everyone to think he is deaf and mute. This has enabled him to hear some of the secrets of the ward because everyone thought it was safe to talk around him. The Chief has also been in the army and in WWII. He claims to hear and see machinery in the walls of the ward that track and monitor all action that goes on in and around the hospital. With his experiences in war and with what he has gone through in the ward, he often loses himself in a "fog". He creates this "fog" in his mind so that he can numb the reality of where he is. Because of how he acts when in this fog, he has remained distant from all other patients in the ward. At least he was until he met McMurphy.

19th Century China

Drawing on what I’ve learned from class discussions and individual research, the 19thcentury in China brought a lot of failure and hardships. It was a time of unhappiness and rapid decline giving it a theme of â€Å"national humiliation†. There was a lot of corruption and rebellion during this period of the time. Around this time China experienced economic regression when foreign interests invaded the country. With the majority of the world expanding and advancing, China found itself on the back burner of this shift into a globalized world.China weakened in the adaption of the new world due to it isolationist ways. This period of rapid political decline and unhappiness was matched with an economic decline as well. China ill-prepared to handle the military and technological distresses from the West in the age of industrialization. Many say that the last few years of the 19th century were by far the worst for China. They had fallen into a state of chaos by the turn of the 20th century. The political structure was a very imbalanced structure in the sense that it did not seek equality.The imperial known as the Manchus were at the top of this political structure. The Manchus came from Manchuria, they ruled from 1644 to 1912 and became nearly conformed into China. The Manchus were known to be the last ruling dynasty to date. They were in charge when the Europeans begun to arrive in vast numbers. Internal trade was very important to China during the 19th century. The silk industry was very important, as it had been for many years. But the balance of the population and the ability to maintain it reached its highest at approximately 1779.Later on, it continued to rise but could not sustain itself at the same time. Accordingly, the orthodox of living and food available for every individual declined greatly. Eventually, with the rise of population, the ability to sustain its people and the average standard of living plummeted. Millions of people starved to d eath in the province of Shaanxi, a third of the population, all in one winter. Near to the end of the 18th century, China’s political administration experienced a tremendous decline. These problems were not very well known, even to the current Emperor.However, In addition to a combination of political and economic issues, the Emperor gave up the throne. Chinese society was made up of a hierarchy, which consisted of male officials. During this time the country was in shambles. The women in China during this time were extremely mistreated and limited. One very unfortunate sign of exploitation women was foot binding which became worse over time. In late 17th century England tried to convince the Chinese emperor to ease restrictions on trading privileges.The Chinese had always felt that they had enough and did not need anything else. With the downfall of political administration and economic failures, multiple wars that resulted in unfair treaties were further intrusions upon the once proud country. These treaties became known as the â€Å"unequal treaties,† made by the British and French after their invasions. In the early 19th century British importers began smuggling opium into China in order to surplus their acquisitions of tea for export to Britain.In 1839, China implemented its prohibitions on importing opium by terminating it, a large quantity of opium seized from the British merchants. Great Britain, which had been trying to end China’s limitations on foreign trade, reacted to this by sending battle ships to attack several Chinese coastal cities. This was known as the first opium war that last for two years. This was the first of many â€Å"Unequal Treaties. † China was defeated by the superior British and was forced to sign the Treaty of Nanjing.In 1850 China experienced the Taiping Rebellion, which is known to be the largest peasant revolution in Chinese history as well as one of the biggest civil wars in world history. The re bellion was anti-Manchu, anti-Confucianism and pro-Christianity movement. This revolutionary movement resulted in a three huge changes in China; it shifted military power from the Manchu to Chinese generals due to the Qing government mobilizing local Chinese army to fight the Taiping. It regionalized China and gave more economic and political power to local influences.This provoked anti-Manchu feelings and led to the end of the Qing Dynasty and the reestablishment of the Chinese nation. China had derived from world economic supremacy to a shattered semi-colonial country with a huge impoverished population. The last few years of the 19th century were China’s toughest ones, causing them to fall into a complete state of disorder as the 20th century was around the corner. This was not a good period for China, but they got past all their hardships and failures with time making them a stronger and more unified nation.

Impact of superior leadership Essay

Introduction Leadership can be defined as â€Å"a process by which a person influences others to accomplish an objective and directs the organization in a way that makes it more cohesive and coherent. Leaders carry out this process by applying their leadership attributes, such as beliefs, values, ethics, character, knowledge, and skills†. (A good leader offers reality check, thank you – The Business Journal of the Greater Triad Area) â€Å"Leadership is concerned with intimacy, intimacy with the substance of the work and with the people you serve,† (What is Leadership?) Nowadays in the world of business, one of the most important issues that companies face is that their workforces, including executives, are incapable of wrapping their minds completely about how to think and act as a superior leader. To become a superior leader, your role in your organization should be lasting success. Besides this, superior leaders must be ambitious, hard working, broad minded, striving, caring, competent, intelligent, cooperative, loyal, dependable, supportive, forward looking, mature, self controlled and so on. Superior leadership motivates us to do more, learn more and dream more. In fact, superior leadership is an approach that unleashes your employees’ brainpower. This is due to the fact that when this brain power is completely utilized, workers and employees are motivated, innovative, creative and committed. How Good Leadership Affects Organization Obviously, we all are aware of the fact that employees are our most significant asset and the best ones are self-starter and self-motivated. Unfortunately, they are approximately only 5 to 6 percent or so naturally occurring. By using a superior leadership strategy, the management can certainly make huge number of employees highly self-motivated and self-started. And in this regard, this superior leadership strategy can be taught to newly hired and prospective managers to maintain your product quality and to provide fineness in leadership. According to Richard Hughes, R&D director for groups â€Å"Specifically, most organizations whether they are in the corporate sector or not have business strategies but have not given sufficient thought to what human capabilities are needed to implement that business strategy effectively†. (McLean, 2005) Furthermore, as a corporate leader of a firm, delivering satisfactory results to your employees, customers, organization and shareholder/investors is your responsibility. Primarily, result-based superior leadership motivates trust, energizes organizational employees and makes performance measurement easier for an organization. Nobody can deny the statement that your company’s overall performance depends upon the fact that how your management plans certain things and applies them in business activities. And with respect of this, a strategic leader should make a caring plan that gives assurance of your company’s goodwill and future business. And to achieve the aforementioned things, the management and the leaders should treat team members as partners instead of employees. In addition to this, a successful leader builds a strong communication connection inside and outside the organization, and understands your stake holders’ and investors’ mutual expectations. Moreover, in order to understand a company’s goals and objectives productively, a workforce should mutually understand and practice its strategy because of the fact that overall success of a company depends upon good leadership. A responsible team leader or manager should apply the aforementioned points. In today’s globalized world of business, many corporations are facing economic, social, political and climatic changes. Hence, a good leader is one who can cope with day to day changing political and social situations. Certainly, true leadership provides business to organizations in any circumstances whatsoever. However, the business environment can have impacts on the style of leadership â€Å"Successful leaders of change may not always be successful leaders of stability, consolidation, continuity, or thriving leaders in periods of massive disruption, such as 9/11. These different conditions require a different style of leadership, which may not necessarily be found in the existing senior management†. (emcc – Transforming organisations – the importance of leadership and culture in managing change) If a strong leadership culture is not present in any type of organization, employees do not contribute a common vision to the organization’s future and would disagree on what the most significant priorities are. In this regard, one would believe that such indicators are influenced according to an organization’s size or in other ways like in which responsibilities are distributed in an organization. In this regard, Marvin Lieberman, Lawrence Lau and Mark Williams conducted a study which is considered a most classy study in the automobile industry. These researchers estimated the productivity equation in order to ascertain the growth in both labor and capital outputs in six companies over a period of forty years. They found that â€Å"effects of top management on all of the companies except Toyota (because it had a system that made performance robust and largely independent of who occupied senior leadership positions) and that these effects were significant† (Pfeffer and Sutton, 2000) Furthermore, there is evidence that leadership results are modest because of the fact that employees who are allowed to keep and hold leadership positions are similar to each other. Practically speaking, leaders are selected for similarity in outlook and education. Consequently, in most of the organizations, leaders who appear to be successful are highly sought after and are likely to take bit positions. Another theorist described his views about leadership and its impacts on your organization as â€Å"building your superior confidence in you requires giving them your confidence. Once you and they have established in both ways, your organization may have an unbeatable competitive advantage, whatever the battlefield†. (Hinders, 2005). Generally, it has been observed that bad leadership has adverse effects on organizational performance and work output. For instance, organizations without proper project management miss milestones. Projects in such organizations cost more than the estimated amount and do not deliver the desired results. Certainly, leadership plays a tremendous role in every aspect of the organization. For example, most of the US financial companies systematically hired the best world talent regardless of the market size and shifted these leaders through every critical and non critical aspect of its operation. Because of the leadership fact, human assets pay off handsomely in today’s global world of business. And in this regard, the world’s best economists also weigh the fact that in today’s business world, it is very difficult to run your business operations economically without having a good leader who has the ability to cope with different problems and solve problems economically and excel among business competitors. Tsun-yan Hsieh and Sara Yik, in an article while emphasizing the leadership importance for an organization stated that, â€Å"â€Å"what do we mean by â€Å"leadership†? Whereas good managers deliver predictable results as promised, as well as occasional incremental improvements, leaders generate breakthroughs in performance. They create something that wasn’t there before by launching a new product, by entering a new market, or by more quickly attaining better operational performance at lower cost, for example. A company’s leadership reaches well beyond a few good men and women at the top. It typically includes the 3 to 5 percent of employees throughout the organization who can deliver breakthroughs in performance†. (Hsieh and Yik).
