Was it Right to Drop the Bomb on Hiroshima and Nagasaki Essay

Was it Right to Drop the Bomb on Hiroshima and Nagasaki - Essay Example Questions on the subject of those nuclear attacks are multifaceted. While it is frequently proposed that â€Å"The Bomb† was the only way to ensure a Japanese surrender, Japan was asking only one concession from the U.S. at the time – the emperor is allowed to remain as head of state. Had the U.S. agreed to this, might have the massive destruction of a principally civilian populace been avoided? Taking this into consideration, it is obligatory for history to question President Truman’s motivations for authorizing its use. Was it really necessary to use this swift resolution to the prolonged deadly war so as to ultimately save many thousands of lives, both American and Japanese, which surely would have been lost if the Americans invaded mainland Japan? Or was the reason, as has been theorized, a decision based more so on keeping the former Soviet Union from having input as regards to the partition of post-war Asia much as it had following the war in Europe? Critic s charge that even given that the first bomb might be justified, the extensive devastation along with the collateral and continuing damage was devastating enough. The second bomb was an unnecessary â€Å"overkill† and should not have been utilized. The main reasoning generally provided to use the bomb was that it saved many thousands of lives on both sides by eradicating the need to fight the Japanese on their homeland, a horrific prospect. When the battles for Okinawa and the Philippines were occurring, President Truman was contemplating a massive ground invasion of Japan’s mainland.

Cost Effectiveness Analysis of Bleach

Cost Effectiveness Analysis of Bleach Household bleach is a common commodity used by all income groups of India. This is mainly because of hot and humid climatic condition which left us with no other choice than white or light colour daily wear clothes. To maintain personal hygiene and attractive look within the available budget it is necessary to use bleaches. One question which bothered me quite often was, when so many bleach brands are accessible, which one is the best to buy and this gave me the idea to frame my research question Investigating the cost-effectiveness of various brands of chlorine-based bleaches containing sodium hypochlorite accessible in Indian Market Thus to determine the usefulness and effectiveness of the bleaches, it was worth calculating the concentration of free chlorine per rupee (Indian currency) spent. The different bleaches were selected and the concentration of the free chlorine was calculated using iodometric titration. The cost per rupee was calculated and comparison was done using statistical tools. After necessary calculations and comparison, it was concluded that the most cost-effective bleach is local bleach. Local bleach has maximum concentration of free chlorine per rupee spent. Although the moles of free chlorine in local bleach is just 0.276mol/dm3 while in that of rin and robin are 0.68mol/dm3 and 0.588mol/dm3 respectively. But the local bleach is quite cheaper to other bleaches. It costs 30 rupees/dm3 while Robin costs 66 rupees/dm3 and Rin costs 80 rupees/dm3. The concentration of free chlorine per rupee spent on bleach is 0.0092mol/dm3 while that of Rin bleach and Robin bleach is 0.0085mol/dm3 and 0.0089mol/dm3. Thus, I conclude that Local Bleach brand is the most cost-effective brand among the three available in India. INTRODUCTION: 1.1 Background As climate of India is hot and humid, people prefer to dress in light or white colour cloth. To keep them clean is a necessity for hygiene. Hence it requires daily washing and using bleach as the light colour fabric expose the stains more easily. When used in approved quantity and right way, bleach removes the nasty stains from white color fabric and brings back the brightness. Looking into Indian economy, it is not possible to buy dresses in large number by masses . Thus easy way out is the use of bleaches. So when I started looking for a topic for my extended essay, my intensions were very clear. I was looking for an area for investigation which will help me to fulfill my requirement to do an essay for my diploma and give me the dual benefit to help my countrymen to choose a better and cost effective bleach which is affordable by them. I have collected the three bleaches which were having the maximum sale in the market , two were branded viz., Rin and Robin and one was a local brand usually purchased by lower income group people. Bleach is a chemical that removes colors or whitens, often via oxidation. Common chemical bleaches include household chlorine bleach, a solution of approximately 3-6% sodium hypochlorite (NaClO), and oxygen bleach, which contains hydrogen peroxide or a peroxide-releasing compound such as sodium perborate, sodium percarbonate, sodium persulfate, tetrasodium pyrophosphate, or urea peroxide together with catalysts and activators, e.g., tetraacetylethylenediamine and/or sodium nonanoyloxybenzenesulfonate.[1] There are other types of bleaches as well for example bleaches which hare used for the bleaching of wood pulp, fats and oils, cellulose, flour, textiles, bee wax, skin etc. the commonly used bleach for this purpose is chlorine dioxide and in a number of other industries. In the food industry, some organic peroxides(benzoyl peroxide,etc.) and other agents (e.g., bromates) are used as flour bleaching and maturing agents. Peracetic acid and ozone are used in the manufacture of paper products, especially newsprint and white Kraft paper.[2] But my investigation is related to household bleach used for removal of stains , which usually contain chlorine, though it often masquerades behind aliases such as sodium hypochlorite or hypochlorite.[3] Household bleach, used to whiten fabrics or remove mold from surfaces, is a 5% solution of a stabilized form of chlorine.[4] It is particularly effective on cotton fiber, which stains easily but bleaches well. Usually 50 to 250 ml of bleach per load is recommended for a standard-size washer. The properties of household bleach that make it effective for removing stains also result in cumulative damage to organic fibers such as cotton, and the useful lifespan of these materials will be shortened with regular bleaching. The sodium hydroxide (NaOH) that is also found in household bleach (as noted later) causes fiber degradation as well. It is not volatile, and residual amounts of NaOH not rinsed out will continue slowly degrading organic fibers in the presence of humidity. For these reasons, if stains are localized, spot treatments should be considered whenever possible. With safety precautions, post-treatment with weak organic acids such as acetic acid (vinegar) will neutralize the NaOH, and volatilize the chlorine from residual hypochlorite. Old t-shirts and cotton sheets that rip easily demonstrate the cost s of laundering with household bleach. Hot water increases the activity of the bleach, owing to the thermal decomposition of hypochlorite which ultimately generates environmentally-undesirable chlorate.[5] Color in most dyes and pigments are produced by molecules, such as beta carotene, which contain chromophores. Chemical bleaches work in one of two ways: An oxidizing bleach works by breaking the chemical bonds that make up the chromophore. This changes the molecule into a different substance that either does not contain a chromophore, or contains a chromophore that does not absorb visible light. Reducing bleach works by converting double bonds in the chromophore into single bonds. This eliminates the ability of the chromophore to absorb visible light.[6] The chlorine based bleaches are oxidized bleach. These bleaches have an edge over reducing bleaches because they act as disinfectant as well. The process of bleaching can be summarized in the following set of chemical reactions: Cl2(aq) + H2O(l) H+(aq) + Cl-(aq) + HClO(aq) The H+ ion of the hypochlorous acid then dissolves into solution, and so the final result is effectively: Cl2 (aq) + H2O (l) 2H+ (aq) + Cl-(aq) + ClO-(aq) Hypochlorite tends to decompose into chloride and a highly reactive form of oxygen: ClO- Cl- +1/2 O2 This oxygen then reacts with organic substances to produce bleaching or antiseptic effects.[7] To begin my investigation I gathered information about brands of chlorine based bleach, its uses and its contents. From the information collected I found out that sodium hypochlorite is an active ingredient in bleaches. Sodium hypochlorite is the magical ingredient which removes stains from the clothes. So if I find out which bleach has the more concentration of sodium hypochlorite and is cheaper than other bleaches will be considered as the best bleach for Indian people. This observation led to my precise topic selection that is Investigating the cost-effectiveness of various brands of chlorine-based bleaches containing sodium hypochlorite accessible in Indian Market After selection of topic next obvious step was to find various methods available in literature and select for an appropriate method for the estimation of the sodium hypochlorite in the bleaches. Various methods available are discussed in the methodology section of my essay. The one I have selected is based on the fact that it is easy to do and also gives a fair estimation of the concentration of hypochlorite in the available laboratory conditions. 1.2 Methods to judge the cost effectiveness of Bleach Some of the methods available in literature for the estimation of concentration of sodium hypochlorite are discussed below: Method 1: One of the common methods is to add excess hydrogen peroxide to a measured amount of bleach. This will result in the formation of oxygen gas. The volume of the gas is collected over water and measured. This is then used to calculate the concentration of sodium hypochlorite in a house hold bleach sample. A few commercial bleaches in their containers, with prices, can be placed on a suitable tray, each with a 10 cm3 syringe and 250 cm3 beaker, both labeled, into which small samples of the bleach can be placed. Measure 5 cm3 of each bleach into their side-arm flask for each experiment. Small samples of the hydrogen peroxide solution could be collected in a 100 cm3 beaker. Bleaches liberate toxic chlorine gas on contact with acids. The chemical reaction involved is H2O2(aq) + NaOCl(aq) à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ H2O(l) + NaCl(aq) + O2(g) Direct comparison of volume of oxygen collected in the measuring cylinder can be used to compare the effectiveness of the bleach.[8] Method 2: Spectophotometric method has also been employed for the quantitative estimation of sodium hypochlorite in commercially available bleach solution. The method is based directly on the absorbance of hypochlorite in alkaline aqueous media. The other method takes advantage of the quantitative reaction of hypochlorite and ammonia in alkaline solution to form chloramine, which has a higher molar absorptivity.[9] Method 3: Another most common laboratory method is IODOMETRIC TITRATION. We can determine the OCl- ion content of a bleaching solution by reacting a known mass or volume of the solution with excess reducing agent, such as iodide ion (I-) in an acidic solution. OCl- (aq, colorless) + 2I-(aq, colorless) + 2H3O+(aq) -> I2(aq, brown) + Cl-(aq, colorless) + 3H2O(l) The reaction above proceeds to completion. Visible evidence of reaction is the change in the appearance of the solution from colorless to brown, due to the formation of iodine (I2). In the presence of excess I- ion, the amount of I2 formed is a measure of the amount of OCl- ion reacting. Then we determine the amount of I2 formed by titrating the I2 with a standard sodium thiosulfate solution (Na2S2O3). The titration reaction for this experiment is shown in the equation below. I2 (aq, brown) + 2 S2O3-2(aq, colorless) > 2I ­- + 2S4O3-2(aq, colorless) Thiosulfate ion is a reducing agent that reacts quantitatively with I2. The titration reaction is complete when the I2 formed from the reaction of OCl ­Ãƒâ€šÃ‚ ­- ion with I ­- ion is reconverted to I- ion by S2O3-2 ion. As the titration proceeds, the I2 concentration in the solution decreases. This causes the solution color to change from brown to pale yellow near the end of titration. The end point occurs when all the I2 has reacted and the solution is colorless. Because the change from yellow to colorless is not very distinct, establishing the end point of this final color change is difficult. We can make the end point more distinct by adding a small amount of starch solution to the titration mixture when the solution turns pale yellow. The unreacted I2 combines with the starch, forming a deep blue complex. The starch molecules tend to curl up into spirals and the hole formed is just the right size for the iodine molecules to fit in. Additional S2O3-2 ion reacts with the complex I2, causing a breakdown of the complex. Disappearance of the blue color signals the end point.[10] We can determine the concentration of OCl- ion in the solution. The moles of iodine in the solution are equal to moles of sodium hypochlorite. So then we can find out the concentration of OCl-. I have used the iodometric titration for my investigation because It is easy to carry it out in school laboratory conditions. Gas volume measurement often leads to more random errors in the measurements which ultimately affect the concentration calculations. Spectrophotometric methods are most reliable method but due to non availability of the instrument, I took the decision to stick to iodometric titration. 2. METHODOLOGY: 2.1 Hypothesis More the sodium thiosulfate used to titrate the solution more effective is the bleach at removing the stains. The bleach which has high concentration of sodium hypochlorite is better at removing stains then the bleach with less concentration of sodium hypochlorite. Based on Indian mentality, the expensive the bleach the better is it at removing the stains. The expensive brand should be more cost effective. 2.2 Selection of bleaches 3 different chlorine-based bleaches containing sodium hypochlorite which are easily available in Indian market. The first one is rin bleach which is thought to be the best bleach because it is expensive of all bleaches available in the market. It costs 40 Rs for 500 ml. The second bleach which I have taken is robin which costs 33 Rs for 500ml, a great competitor to RIN. And the third bleach which I have taken is bleach from a local brand which costs only 15Rs for 500ml. 2.3 Experiment 1 Make a soya bean solution using 17 grams of soyabean and dissolved up to 100 cm3 mark. Put three drops of the solution on a piece of cloth and using a syringe the amount of bleach required to remove the stain should be noted down. 2.4 Experiment 2 As told earlier I will be using titration with sodium thiosulfate for calculating the concentration of sodium thiosulfate in the bleaches. The method involves two main steps. Step 1: Standardizing the solution of sodium thiosulfate solution As sodium thiosulfate is not a primary standard, so it was standardized using a known concentration of potassium iodate KIO3 and the exact concentration of sodium thiosulfate was calculated. Approximately 8.00 ±0.01 grams of sodium thiosulfate (Na2S2O3 5H2O) was taken a 100 cm3 beaker and dissolved by adding small amount of double distilled water. It was stirred using a glass rod till it was completely dissolved. Solution was transferred to 250 cm3 of standard flask carefully using a funnel. Solution was made up to the mark and mixed well by tilting the flask three times. A solution of potassium iodate, KIO3 (0.2 Mole/dm3) was prepared by dissolving 10.7 ±0.01 grams of KIO3 in 100 cm3 beaker and dissolving it in minimum amount of water and making the solution in 250 cm3 standard flask. Further 25.0 ±0.06 cm3 of KIO3 solution is pipette out using a 25.0 ±0.06 cm3 pipette and a pipette filler and poured in standard measuring flask and solution was made 250 cm3 using distilled water. Preparation of 1 mol/dm3 of sulfuric acid Take 55cm3 of 98% pure sulphuric acid in 100cm3 measuring flask. Now slowly pour this acid into 500cm3 of constantly stirred water in a beaker Now transfer this solution into 1dm3 conical flask and add water till the 1dm3 mark. Preparation of 10% potassium iodide Take 10grams of potassium iodide Dissolve it in 100cm3 solution Preparation of 2%starch indicator Take 2grams of starch Add little bit of cold water until a smooth paste is obtained Add 100cm3 of boiling water and stir Heat the solution until the solution is clear 25.0 ±0.06 cm3 of KIO3 solution is pipette out using a 25.0 ±0.06 cm3 pipette and a pipette filler and poured in conical flask. 10.00 ±0.05 cm3 of potassium iodide (10% w/v) is added to the flask using a measuring cylinder. To this solution 10 .00 ±0.05 cm3 of sulfuric acid (1 mol/dm3) is added to the flask using another measuring cylinder. Sodium thiosulfate is filled in 50.00 ±0.05 cm3 burette and added to the conical flask containing KIO3, KI and H2SO4solution till the solution in the conical flask turned pale yellow. 2 to 3 drops of starch solution (1% w/v) was added to the conical flask. The solution turned blue black. More sodium thiosulfate was added to the conical flask with constant swirling till the solution turned colorless. The final volume of thiosulfate solution added is recorded Three concordant readings are taken to have consistency in the recorded data Step 2: Titration of the different brands of bleaches using standardized solution of sodium thiosulfate. Thus calculating the concentration of sodium hypochlorite present in different brands of bleaches. Procedure: I have taken 25.0 ±0.06cm3 of Rin bleach using a pipette and pipette filler into 250cm3 graduated flask. To this water was added to make the solution up to 250cm3 mark. 25.0 ±0.06cm3 of the solution poured with the help of pipette into a conical flask and the same procedure as given above was repeated with RIN bleach followed by the other two bleaches, Robin and local brand. 3. Data collection and processing: 3.1 Finding out the concentration of Sodium Thiosulfate Standardization of sodium thiosulfate: Volume of potassium iodate taken in conical flask = 25.0 ±0.06 cm3 final burette reading / cm3 ±0.05cm3 20.10 19.90 20.00 initial burette reading / cm3 ±0.05cm3 0.00 0.00 0.00 volume of sodium thiosulfate used / cm3 ±0.1cm3 20.10 19.90 20.00 Average volume of sodium thiosulfate used = 20.00 cm3 Calculations: 25.0 cm3 of KIO3 solution required 20.00 cm3 of Sodium thiosulfate. The ionic equation related to the titration is IO3-1 + 5I-1 + 6H+  ® 3I2 + 3H2O The I2 produced by the reaction between iodate ion and iodide ion is related stoichiometrically to thiosulfate ion as follows I2 + 2S2O32-  ® S4O62- + 2I-1 Moles of KIO3 (0.1 Mol/dm3) in diluted solution = 0.01 mol/dm3 Moles of 0.01 mol/dm3 KIO3 in 25 cm3 of solution = 0.01 x 25 x 10-3 = 0.25 x10-3 Ratio of moles of KIO3: I2 1 : 5 So moles of I2 in solution = 5 x 1 x 0.25 x10-3 = 1.25 x10-3 Ratio of moles of I2 : S2O32- 1 : 2 Therefore moles of thiosulfate = 2 x 1 x 1.25 x10-3 = 2.50 x 10-3 20.00 cm3 of thiosulfate solution has 2.50 x 10-3 moles Therefore the concentration of thiosulfate solution = 2.50 x 10-3 x 103/20.00 = 0.125 mol/dm3 3.2 collection T value for the t- test between RIN and ROBIN is 36.83644 This value is a lot higher than the cut off value (2.31. using degrees of freedom= [n1-1] + [n2-1] = 8) at a 5% significance level. This implies that there is lot lesser than .1% chance that the 2sets of readings belong to one population or the difference is just difference is insignificant. 3.3 Calculation 25.0 cm3 of diluted Rin brand bleach solution required 27.8 cm3 of Sodium thiosulfate. Moles of sodium thiosulphate= Moles of iodine, I2, were present in the conical flask after the bleach reacted with an excess of iodide ions 2S2O32-(aq) + I2(aq) S4O62-(aq) + 2I-(aq) Moles of I2 = moles of sodium thiosulphate à · 2 Moles of I2 = 0.00348 à · 2 Moles of I2 = 0.0017 moles 1 mol of iodine is displaced by 1 mol of free chlorine. Cl 2(aq) + 2I-(aq) 2Cl-(aq) + I2 (aq) The free chlorine concentration, in mol dm-3, of the bleach RIN 1 mole iodine = 1 mole of free chlorine à ¢Ã‹â€ Ã‚ ´25cm3 of diluted bleach solution contains 0.0017 moles of chlorine Therefore the undiluted bleach solution of 25 cm3 would contain .017 moles Concentration of iodine in 500 cm3 of RIN bleach solution is Therefore the concentration is 0.34mol/500cm3 of RIN bleach. Therefore the concentration is 0.68mol/dm3. 25.0 cm3 of diluted Robin brand bleach solution required 23.53 cm3 of Sodium thiosulfate. Moles of sodium thiosulphate= Moles of iodine, I2, were present in the conical flask after the bleach reacted with an excess of iodide ions 2S2O32-(aq) + I2(aq) S4O62-(aq) + 2I-(aq) Moles of I2 = moles of sodium thiosulphate à · 2 Moles of I2 = 0.00294 à · 2 Moles of I2 = 0.00147 moles 1 mol of iodine is displaced by 1 mol of free chlorine. Cl 2(aq) + 2I-(aq) 2Cl-(aq) + I2 (aq) The free chlorine concentration, in mol dm-3, of the bleach RIN 1 mole iodine = 1 mole of free chlorine à ¢Ã‹â€ Ã‚ ´25cm3 of dilute bleach solution contains 0.00147 moles of chlorine Concentration of iodine in 500 cm3 of Robin bleach solution is Therefore the concentration is 0.294 mol/500cm3 of Robin bleach. Therefore the concentration is 0.588mol/dm3. 25.0 cm3 of diluted LOCAL brand bleach solution required 11.07 cm3 of Sodium thiosulfate. Moles of sodium thiosulphate= Moles of iodine, I2, were present in the conical flask after the bleach reacted with an excess of iodide ions 2S2O32-(aq) + I2(aq) S4O62-(aq) + 2I-(aq) Moles of I2 = moles of sodium thiosulphate à · 2 Moles of I2 = à · 2 Moles of I2 = 0.00069 moles 1 mol of iodine is displaced by 1 mol of free chlorine. Cl 2(aq) + 2I-(aq) 2Cl-(aq) + I2 (aq) The free chlorine concentration, in mol dm-3, of the bleach RIN 1 mole iodine = 1 mole of free chlorine à ¢Ã‹â€ Ã‚ ´25cm3 of diluted bleach solution contains 0.00069 moles of chlorine Concentration of iodine in 500 cm3 of Local bleach solution is Therefore the concentration is 0.138mol/500cm3 of RIN bleach. Therefore the concentration is 0.276mol/dm3. 3.4 analysis and interpretation Calculating the cost-effectiveness BRAND RIN ROBIN LOCAL Concentration of free chlorine (mol/dm3) 0.68 0.588 0.276 Price of 500cm3 bleach in rupees 40 33 15 Price of 1dm3 bleach (=price of 500cm3ÃÆ'-2) in rupees 80 66 30 Concentration of free chlorine per rupee spent on bleach (=concentration of free chlorine in 1dm3 bleach/price of 1 dm3 bleach) 0.0085 0.0089 0.0092 Matrix 1 It can be seen from the experiment 1 higher amounts of bleach is used to remove the stain as we move from RIN to ROBIN to the local brand. And as it can also be seen from the histogram above (graph 1) that the free chlorine concentration decreases as we move from RIN to ROBIN to the local brand it can be inferred that higher the concentration lesser is the amount of bleach required. How so ever the amount of free chlorine required is nearly the same 4. Conclusion: 4.1 Results The free chlorine concentration per rupee spent is maximum of local brand bleach. Therefore the local bleach is most cost-effective bleach. The local brand bleach over takes other branded bleaches like RIN and Robin which are very famous in Indian market. There is a very small difference between each of them when we calculate the concentration of free chlorine per rupee spent. But when we see the concentration of free chlorine in rin and robin they are quite higher then local brand. Local brand has very less moles of sodium hypochlorite per dm3 of the bleach. So the volume required to remove a stain by local brand bleach would be quite large then the volume required of rin or robin brand bleach. This can give a wrong impression that the other brands are better or more efficient at removing stain. But we know that it isnt so. Only if higher amounts of the local brands were used the same stain would take lesser money to be removed. This proves the Indian mentality. Resolved questions Is the amount of sodium thiosulfate used proportional to the amount of free chlorine atoms- Yes very much. It can be inferred by comparing graph 1 (or matrix 1) and graph 2 Does the concentration of sodium hypochlorite affect the effectiveness of the bleach- Higher the concentration of sodium hypochlorite more is the effectiveness of the bleach. Inferred from graph 1 (or matrix 1) and table 1 Checking the Indian mentality- It depends on the amount of bleach used. But it can easily be inferred that the local brand is a lot more cost efficient Deriving the cost effectiveness of different brands of bleach Hypothesis 1 and 2 were confirmed to be true via experimentation while the other two hypotheses (namely 3 and 4) are proved to be wrong. Evaluation Weaknesses It isnt very easy to note down the point of the end of the titration. Accuracy can tend to pose a problem The distil water can have other salts present Improvements Colorimetry should be used for knowing the end point More accurate burettes can be used Ultra pure water should be used rather than distilled water 4.2 Extension The other method should be used. A more number of brands should be used. Other active ingredients should be tested for. Biologically active organisms like bacterias should also be considered. The activity of the other active substances should be tested. 5.

Pat Barkers Regeneration Essay -- Birth Control Pregnancy Essays

Contraception is a word commonly used in society today. With hundreds of types, brands, and methods of contraception available, it is hard to imagine a world without it or one in which it was against the law. However, decades ago at the turn of the 20th century, birth control was not easy to get or looked upon as socially acceptable. It was during the First World War that society began to see the emergence of contraception and its acceptance. Readers can also see its emergence in Regeneration on page 128, as Billy Prior propositions his new love interest by stating he "always paddles with me boots on," a reference to the fact that he, as an army man, always wears contraception when having intercourse. With this background, we can now see how Pat Barker uses this brief cultural reference to remind readers of the history of contraception for both men and women during the war and to suggest how people can find emotionally fulfilling and loving personal relationships through sex, a main theme in the novel. Many men during the war were soldiers. With the constant travel and movement of their platoons, soldiers did not stay in one place or, for that matter, with one girl. Consequently, during the First World War, condoms were handed out to soldiers as a preventative measure against the spread of venereal disease (Robb 65). Because soldiers would sometimes have many partners, condoms became a necessity to carry. Lesley A.

Impact of Applied Agro-Cooperative Credit and Banking on Farmers and Farming

People depend for good introduction in Agro-Farming not only on good seeds, good fertilizers, good irrigation and good Agro-technology; but they need also short-term, medium and long term loans to meet their other demands at farm level in farming. This genuine situational scene has a power to present an impact of applied cooperative credit and banking on farmers in farming from the point of origin of the Indian Cooperative Credit (a facile credit) movement from the period of working of NIDISH in Madras Province in 1882 to 1904 till date. This is a good Genesis of this issue with a scientific periodicity which may be perused in following section. An Iota in the facile cooperative credit scene of madras province Nidish a socio-economic social group were working in very active form like the primary cooperative credit societies at farm level in rural Madras province in 1882-1884. Madras Provinces 1882-1884 :- Fedaric Nicholson’s visit from India to Germany to study the working of The Raiffieson Model Rural Cooperative Credit societies and came back with a finding â€Å"Find Raiffieson† because he found 100% similarities in need of Agro – financing for Rural India, with cultural similarities at great scale in rural India and Rural Germany. In India also there was great exploitation done by private moneylenders by charging 75% rate of interest and in Germany also such high interest was taken by Jews/Nazis from Rural Germany Farmers. The profit motive and usurious practices were similar in India and Germany. In 1882 to 1884 Fedaric Nicholson came back from Germany in Madras Province and recommended to the government to start primary Agro-Cooperative credit and Banking instead of Nidish to protect rural people from great exploitation and usurious practices of private money lender. His report and recommendations were accepted by the Madras provincial government under the control of British government. This was also studied and accepted by the government of Bombay province Maharashtra due to great vitality in his recommendations in public interest. In 1896, the British government appointed Edward committee (sir Edward as chairman) to study the Indian Rural conditions, needs and scope of working of the primary Agricultural Cooperative Credit societies under the control of British government for the people to work with cooperation of the people for the people with democratic management at grass root level. The Edward Committee 1896-1904 surveyed the Indian Rural agro-banking system and passed first cooperative Societies Act 1904 which was accepted and made applicable for greater India (from Kabul to Burma) with democratic centralised cooperative credit banking; viz; from Kabul to Burma, if any primary Agricultural cooperative society was organised, then it was bound to get registration from Delhi only. This was a real scene from 1904-1908. The distance factor was main problem for for mation and registration of Agro-primary Cooperative Credit Societies. In this era cooperative credit was considered as a facile credit and cooperative banking was accepted a means to achieve the desired goal in a desired time. In 1908, Lawd recommended to add cooperative Audit, with cooperative credit and banking by increasing two sections in the cooperative Act of 1904. Thus total sections from 48 to 50 were made in the first cooperative society’s act of 1904 in 1908-1912. This added great strength to Agro-cooperative credit and banking system for Rural India. In 1912, the cooperative society Act was again examined by Sir Malcolm I. C. S and others. They suggested to add three sections more for facilitating cooperative credit, Consumption, and Marketing to the people of Rural India to protect them from exploitation of private traders and took them away from cruel clutches of exploiters by using cooperative organisation of the people for the people. It was accepted by the government in public interest. In 1914-1915, the cooperation was made state sponsored subject to give chance to the state (provincial governments) to frame their own cooperative society Acts on the basis of this model Act of 1904 with due consideration of the interpersonal situations of the concern state in preparation of their own cooperative societies act. It gave good chance to states from Kabul to Burma to register primary Agro-cooperative credit societies for credit and banking activities according to their interpersonal conditions to work and upgrade socio-economic life of rural people by effective working of primary Agro-cooperative credit and banking business. There was a rapid growth of members of primary Agro-cooperative credit and banking business and growth also found in qualities of services from 1912-1915 in cooperative credit movement in India. The first world war of 1915 gave great shock for the growth of Rural Agro-Cooperative banking due to more involvement of rural people in Indian Army. Therefore there was stunted growth of working of Agro-cooperative credit and banking from 1915 to 1925. There was Second World War in 1930-1935. The Burma separated from India in 1920 and Shyam, Rangun and Kabul were also separated in 1937-38 and became independent countries. These newly made countries accepted and used Indian model cooperative society Act of 1912-15 to make their own cooperative acts. In 1939-40 in India, the Vijayraghavacharya committee recommended to start linking of cooperative credit with Agro-production and marketing in Madras provinces in Salem district. It was applied in Salem district only for testing. India became independent country in 1947 from the clutches of britishood separate it. The public finance sub-committee (headed by Dr. D. R. Godgil) in 1946 submitted its report and recommended to allow crop loan systems to Rural people (farmers) to bring new change in farm financing by deciding Maximum Cooperative Credit Limit (M. C. L. ) per farmer, per acre per crop per season to upgrade economic strength of rural borrowers on the one hand by weathering the deep rooted exploitation of private moneylenders which gave a good chance for effective working of rural Agro-cooperative credit and banking on the other. It was again reviewed by Thakurdas Mehta committee in 1948. This committee recommended starting its application from April 1950 in First Five Year Plan. At this time Ready Recknor was not made crop-wise for farmers but Rs. 500 M. C. L. (Maximum Credit Limit) per acre per crop was approved to apply from 1951 to 1954 in the first five year plan for good financing to farmers through primary Agro-Cooperative credit societies. It was brought in real practices. In 1950-54, A. G. Gorwala I. C. S was appointed to do All India Rural Credit Survey to judge the extent of credit distribution by the cooperative credit societies in presence of several moneylenders. He did survey in 75 districts of India, in 400 villages and 127475 farmers families who found 3. 5% farm financing and banking was done since 1904 to 1954 by cooperative credit societies and 96. 5% was done by non-cooperative agencies. The extent of linking of cooperative credit with farm production and cooperative marketing was found 1 % only. There was major failure of cooperative credit and banking role in rural India in socio-economic upgradation process for farming community. The AIRCS committee 1954 gave remark, â€Å"Cooperative have failed but must succeed. † The AIRCS committee recommended starting CCR (controlled credit recovery) scheme under integrated Approach, viz: linking of cooperative credit with farm production and cooperative marketing to upgrade socio-economic life of farmers on the one hand and quality of services of cooperative credit and banking on the other. This recommendation was applied in second five year plan from 1955 to 1960. It was found that linking of cooperative credit and marketing increased from 1% to 11% and extent of cooperative credit distribution was increased from 3. 5% to 30% and maximum credit limit (MCL) increased from Rs. 500 to Rs. 1200 per crop per acre per year. This gradual growth gave great encouragement to cooperative credit and banking system in farm financing at a great length. This had motivated for a reliable and very valid effective approach through cooperative credit and banking for rural reorientation as well as upgradation of socio-economic change of rural people in rural India. This indicated a good desired shifting of cooperative credit business and gave a motivation to cooperative sector to face challenge for a desired change at farm level in the system of farming with Agro-technology. If we examine socio-economic changes from 1950 to 2012 or from first five year plan to 11th five year plan through applied cooperative credit and banking, the desired changes are found based on multiple variables with varieties of risks (challenges for changes). This scene is inviting attention of planners, surveyors, researchers and the governments to identify factors or obstacles affecting in achieving the desired results. Nobody has made any attempt on this issue at a great length till date to identify the factors affecting the quality of socio-economic change operation of cooperative credit and rural banking practices. There is urgent need and demand of the rural people, primary Agro-cooperative credit societies and applied cooperative banking to identify the problem raising factors and discover reliable and valid solutions to achieve the desired goal in the desired time. Therefore, an attempt is needed to make on this issue. The present study aims to work on this issue at a great length. Objectives of the study Broadly speaking, this study has main following objectives:- 1. To identify/ analyse the reliable and valid factors affecting the working of applied cooperative credit and banking at grassroots level and also to identify socio-economic changes at farm level and; 2. To explore practical possible solutions as remedial measures to solve the problems at grass root levels, to do socio-economic upgradation of farmers and their farming with help of modern Agro-technology and rational farm financing. Research Design The present study is going to do Exploratory-cum-Descriptive research work. It is a systematic and purposeful empirical enquiry; it includes surveys and fact-findings enquiries of different kinds. The main characteristics of this method are that the researcher has no control over the variables. It only reports what has happened or what is happening. In which the researcher does not have direct control over independent variables either what has happened or what is happening. But in this solution by the research an attempt has to make to search reliable and valid factors to discover a good solution for solving the problems. Location of the Universe/ Population B. R.

The Effect of Baroque Music Essays

The Effect of Baroque Music Essays The Effect of Baroque Music Paper The Effect of Baroque Music Paper The Effect of Baroque Music on the Performance of Elementary Students on Problem Solving Task A Research Proposal Submitted to the Faculty College of Liberal Arts Western Mindanao State University In partial fulfillment of the requirements in Psychological Research I Submitted by: Lilibeth Grifon Christie Annie M. Jalaron Audraiza Macaraya Arlynn Mae Tangon Chapter I Introduction Students’ lives today are filled with large variety of experiences by which they develop either positive or negative attitudes toward certain experiences. Eventually, these attitudes develop into a guide to their behavior. It has been noticed that most school learners are now musically inclined and the need to have a better teaching strategy to facilitate students’ learning abilities is the prime reason why researchers want to pursue this study. This study focuses on the application of background music in the classroom setting to find out if providing music in the environment can have a significant difference in learners’ performance. The influence of music on rates of learning has been the subject of study for many years. Research has confirmed that loud, background noise hinders learning concentration, and information acquisition. Background music is used to provide a welcoming atmosphere and help prepare and motivate students for learning tasks. It can energize lagging attention levels or soothe and calm when necessary. Music in the classroom may have different effects, depending on the strengths and weaknesses of the pupils in the classroom. It may also depend on the existing level of noise at the school and surrounding area. Various researchers reported that kids seem to be vulnerable to excessive noise. For children who are sensitive, environmental noise can be a source of stress. That’s why for the past years, researchers experimented many ways of producing the healthiest sound possible. Several researchers have proven that classical and baroque music with some nature sounds are the most appropriate background music. Some amount of background music may be helpful in the learning process. Original studies in the used of music in learning show that Baroque music was optimal for learning. Another study showed that Baroque music accelerates learning, and enhance both short-term and long-term memory. Baroque music, with its unique rhythmic structure and stability, is particularly conducive to memory, productivity and healthy, stress-free environments (Lawrence, 2001). Baroque music describes an era and a set of styles of European classical music which were in widespread use between approximately 1600 and 1750. The original meaning of baroque is irregular pearl. Baroque music forms a major portion of the classical music canon, being widely studied, performed, and listened to. Baroque composers include J. S. Bach, Antonio Vivaldi, Handel, Chopin, Pachelbel and Alboni. Background of the Study Mathematics is a subject where most learners have low achievement. Different reasons are presented on why learners have difficulty in dealing with math subjects. It even came to the point wherein learners cut classes during math subjects. Some respondents stated why they have low interest in math is because they get bored with numbers and teacher’s chalk-board strategy is even reinforcing their boredom. Problem solving is a process of thinking that is directed toward the solution of a specific problem. The process involves the use of problem solving skills. Yet the most difficult to teach in Mathematics is problem solving. Even high school students could hardly solve two-step problems. This is due to poor analysis and understanding of word problems. Proficiency in remediating the problem experienced by the students in this area is an essential skill of a competent educator (Miranda, 2004) One reason of boredom is the lack of interest but more so with the lack of environmental stimulation. Enriched environment is one of the most important factors that educators should look into for the reason that learners are widely curious with different stimuli that will encourage them to do their best in every endeavor. Several researches show that instrumental music can enrich environment and can cause stimulation to learners which is present in the change of their physiological processes. Review of Related Literature This section will discuss the study of the effect of background music in learning. It also includes literature and studies on the effect of music in learning performance. This section will provide scientific evidence that support the claim that music is related to the improvement of mathematical performance. (Tria, Limpingco, Jao, -) concrete operational stage is a period of concrete operational logical thought in number, class and orders (7-11 years old). The child becomes increasingly capable of demonstrating logical thinking in relation to physical objects. A newly acquired capacity of reversibility allow him or her to mentally reverse action that was previously only than physically. The child is now able to mentally hold two or more variables at a time when studying objects and to reconcile apparently contradictory data. He or she becomes more sociocentric, increasingly aware of the views of others. These new mental capacities are demonstrated by a rapid growth in the ability to conserve certain properties and to do relational thinking such as classifying and ordering objects. Mathematical operations are also developed. The child becomes increasingly able to think of physically absent things based on the vivid images of past experiences. The child’s thinking, however, is restricted to concrete thing rather than ideas. (Hurlock, 1982) stated in her book that educators call late childhood the elementary school age. It is the time when the child is expected to acquire the rudiments of knowledge that are considered essential for successful adjustment to adult life. It is also the time when the child is expected to learn certain essential skills, both curricular and extracurricular. Educators also regard late childhood as a critical period in the achievement drive –a time when children form the habit of being achievers, underachievers or overachievers. Once formed, habits of working below, above, or up to one’s capacity tend to persist into adulthood. It has been reported that the level of achievement behavior in childhood is highly corrected with achievement behavior in adulthood. As their world expands with their entrance into school, so do children’s interest. And with this broadening of interest comes an understanding of people and things which formerly had little or no meaning. Children now enter Piaget has called the â€Å"Stage of concrete operations† in thinking, a time when the vague and nebulous concepts of early childhood become specific and concrete. With rapid growth comes a sapping energy. This leads to a disciplination to work and to attitudes of boredom toward any activities that require effort on the individual’s part. While underachievement after begins around the fourth or fifth grade in school, when early enchantment with school gives way to disenchantment, it generally reaches its peak during puberty. Barr and Seashore (as cited in Kong, 2005) says that it is easy to see how active listening can be applied to the steps for teaching toward conceptual change. Once a student has internalized the skills for active listening, they are primed for engaging in an active learning process. The exhibition of this capability is limited by the child’s ability to understand or apply himself to the task. It stressed that researchers and educators have further identified active listening and its component skills as being transferred across disciplines. The ability to listen effectively affects students’ chievement in school, and contributes to the success in life. Music among the multiple intelligences was found invaluable to develop student’s abilities in listening. Insofar as the power of reflective thinking is concern, musical intelligences are like philosophical, mathematical or scientific intelligence. Hodges (2000) outlines the five basic premises that have been derived from neuromusical research. These premises establish a link between the human brain, the ability to learn and the capacity for resilient health. This research supports the long held supposition that music is beneficial to human beings. He states: (1) human brain has the ability to respond to and participate in music; (2) musical brain operates to respond at birth throughout life; (3)early and ongoing musical training affects the organization of the musical brain; (4) musical brain consists of extensive neural systems involving widely distributed, but locally specialized regions of the brain: cognitive components, affective components, and motor components. O’donell (1999) stated that Music from the baroque period causes the heart beat and pulse rate to relax to the beat of music. It affects the amplitude and frequency of brain waves, which can be measured by an electro-encephalogram. Music also affects breathing rate and electrical resistance of the skin. It activates the left and right brain, thus, maximizes learning and retention of information. The information being studied activates the left brain while the music activates the right brain. In addition, he also find out that listening to baroque music before taking a test releases neurons in the brain which will help the body to relax. Its effectiveness can be seen by the results from an IQ test performed on two groups of college students. The first group listened to Mozart music before taking the test. The second group did not listen to music before taking the test. The first group had an average of 119 while the second group had an average of 110 only. In addition, he stated that the key component of music that makes it beneficial is the order. The order of the music from the baroque and classical periods causes the brain to respond in special ways. This order includes repetition and changes, certain patterns of rhythm, and pitch and mood contrasts. The brain works by looking at the different pieces of information and deciding if they are different or the same. This is done in baroque and classical periods by playing a theme and then repeating and changing the theme. The repetition is only done once. More than one repetition causes the music to be come displeasing, and also causes the person to either enter a state of sub-conscious thinking or a state of anger. Accordingly, the human mind shuts down after three or four repetition of rhythm, or a melody, or a harmonic progression. Zatorre (as cited in O’donell, 1999) children pay close attention to subtle variations in tone and timing, which enables them to learn language accent perfectly. Likewise, musical people have increased aptitude in foreign language learning due to an advanced ability in perceiving, processing, and closely reproducing accent. When the brain processes music, this function extends over both hemispheric regions. The primary actuator in this connection is the acoustic cranial nerve which acts as a switching station for cranial nerves. In other words, the acoustic nerve channels not only sound from the ear, but also conduct other sensory inputs together, so our experience of the environment necessarily becomes a synthesis. Shaw and Bodner (as cited in Kliewer, 2003) included in their study the used of magnetic resonance imaging (MRI) to map the regions of a subject’s brain that respond when listening to Mozart and Beethoven, and they found out that all types of music activates the auditory cortex, where the brain process sound, and sometimes trigger parts of the brain that are associated with emotion. But with Mozart and Beethoven’s music, the whole cortex is lighting up. Also, it activates areas of the brain involved in fine motor coordination, vision and other higher thought processes, all of which might be expected to come into play for spatial reasoning. Lawrence (2001) found that several studies used instrumental soothing music tends to help accelerate learning. Examples include the composition of Mozart, Vivaldi, Bach and Handel. These instrumental pieces are called concentration music or relaxation music. Baroque music, with its unique rhythmic structure and stability, is particular conducive to memory, productivity and healthy, stress-free environments. Studies for accelerated learning showed that Baroque music was optimal for learning. This music also provides health benefits such as lower muscle tension, lower blood pressure, and a slower pulse rate. Rauscher et al (1988) determined that listening to 10 minutes of Mozarts Sonata for Two Pianos in D Major briefly increased scores 48% (relative to control groups) on the paper-folding task, a component of the Stanford-Binet intelligence test that measures spatio-temporal reasoning abilities. Moreover, the effects were transient, lasting only about 10 minutes, and performance on non-spatial reasoning tasks was unaffected. Such results seem to be unique to the music of Mozart, whereas music not as highly structured did not have measurable effects. Other researchers have demonstrated that compositions of other classical composers such as J. S. Bach show similar benefits. Lozanov (1960) found that playing Baroque instrumental music (such as that of Handel and J. S. Bach) in the background while teaching foreign language vocabulary greatly increased students speed of learning and degree of memory retention. Music with a meter close to 60 beats per minute was found to be most effective; that this rate closely matches that of a relaxed pulse is thought to be significant. Merrill (1991) got 72 mice and divided them into three groups: the hard rock group, the Mozart group, and the control group who had no music at all. He placed the mice in aquariums, and then started playing music 10 hours a day. He put each mouse through a maze three times a week that originally had taken the mice an average of 10 minutes to complete. Over time, the 24 mice in the control group were able to cut about 5 minutes from their maze completion time. The Mozart mice cut their time back 8 1/2 minutes. The hard rock mice added 20 minutes to their time, a 300% increase in maze-running time from their original average. Unfortunately, the study did not go for long because all hard rock mice killed each other. Hardie (1990) studied the effect of music on mathematics anxiety and achievement. Two different environments were used while students took an Intermediate Algebra exam. One group took the exam in silence, while the other group listened to background music during the exam. There was a significant increase in anxiety for the students tested in silence. Ruvinshteyn and Parrino (as cited in Orel, 2007) says research over the past 40 years, Baroque music pulses between 50-60 beats per minute and has been shown to enhance learning of foreign languages and to improve performances in some types of tests. Because of this, the music has been widely marketed as a learning tool. The faculty members studied two groups of classes at Essex County College. In the first group, the instructor played baroque-style music in the background during the first semester. The second group, taught by the same instructors, was not exposed to music during class time. After the first month, surveys showed that students who listened to music were more likely to enjoy class (86 percent vs. 76 percent) and less likely to find mathematics challenging (33 percent vs. 46 percent). Similar changes were noted in both groups regardless of which instructor taught the course. Preliminary results also indicated an improvement in student grades. Weber (2007) stated that Baroque music accelerates learning and enhances both short-term and long-term memory. Physiological effects of Baroque music on learners includes lowering of the blood pressure slows heart beat, decrease of beta waves by 6% but increase of alpha waves by an average of 6%, and the right and left brain hemispheres of the brain synchronized. As the body becomes relax and alert, the mind is able to concentrate more easily. Mowesian and Heyer (1973) tested the basic arithmetic skills of tenth grade students under five different music style conditions: silence, rock music, folk music, classical-instrumental, and classical-vocal. No significant mean exam score differences were found among the five music conditions. They suggested that because music or some other distracter so frequently accompanies participants studying, music may be assumed to raise their morale (p. 108) and that music may make studying and test-taking less tedious, boring, and anxiety-producing (p. 108). Wolfe (1983) researched the use of four volume levels of music while computing mathematics problems. Participants, 200 undergraduate non-music majors, were randomly assigned to 4 treatment groups. The groups were task only (no music), task plus background music at 60 – 70 dB, task plus background music at 70– 80 dB, and task plus background music at 80 – 90 dB. For the three music groups, the music consisted of four instrumental selections from motion picture sound tracks. The results indicated no significant difference in the number of problems completed by each group. Also there was no significant difference in the number of math problems completed correctly among the four groups. The participants were given a questionnaire concerning the effect of the loudness on their ability to complete the task. More participants in the 80 90 decibel music group felt that the loudness of the musical selections seemed to interfere with computing the math problems. Theoretical Framework This study anchors on the theory of human intelligence developed by psychologist Howard Gardner who suggested that there are several ways of perceiving and understanding the world that allow individuals to find and resolve problems they faced. This also interrelates the theory of Burrhus F. Skinner and Edward C. Tolman on the role of environment in learning. In 1983 Howard Gardner, psychology professor at Harvard University, presented his Multiple Intelligence theory based upon many years of research. Promoting the concept that intelligence is not one entity but that there are many different forms of intelligence, Gardner has awakened a revolution in learning. Multiple Intelligence teaching methods recognize eight (though there may be more) forms of intelligence: visual-spatial, linguistic, logical-mathematical, bodily-kinesthetic, interpersonal, intrapersonal, musical, and most recently naturalist. Multiple Intelligence teachers strive to broaden students’ familiarity and skill levels in each area. In introducing musical intelligence, Gardner first stands back and identifies its basic core of objective features: rhythm, pitch, harmony, and timbre, but he soon moves closer to dwell on the mysterious emotional power of music. He then presents several kinds of evidence to support his theory that musical ability functions like intelligencewhat composers have called logical musical thinking and the musical mind. Musical abilities illustrate why Gardner rejects the simpler split-brain concept of mind. Although most musical abilities are located in the right hemisphere, trained musicians are likely to draw upon the left hemisphere in solving a task that the novice tackles primarily through the use of right hemisphere mechanisms. The Multiple Intelligence teaching model emphasizes education for understanding rather than rote memory or the mimicking of skills. Practical hands-on skill development is coupled with factual knowledge and the ability to apply skills and information in real-life situations and make meaningful contributions to society. Development of the musical intelligence can be greatly aided by the use of music throughout the curriculum. In addition to learning about musical elements and how to create music, the musical intelligence involves developing an ability to respond to musical sound and the ability to use music effectively in ones life. Edward C. Tolman (1886-1959), in his theory Sign/Purposive Learning indicates that cognitive processes are acquired relationships between environmental stimuli and responses. In his theory, the learner recognizes the significance of a stimulus and its different eatures. By following a series of recognizable signs toward a specific goal, learning becomes purposeful. His definition of stimulus is a perception, it is an environmental event that is processed by the organism, and definition of response is a learned behavior composed of performances. Burrhus F. Skinner (1904-1990), his theory Instrumental Learning contends that the most significant human behavior falls under the general heading of operant behavior, which means that there are observable stimuli that lead to human action. His basic approach is a functional analysis of the relationship between observable behavior and the external variables that identify those elements of the environment associated with the occurrence of a behavior or a response. Manipulation of the environment is involved to produce the desired behavior. Conceptual Framework Since learning is a function of the multiple intelligences inherent in the learner this study looks into the causal relationship between Baroque music and performance in Math problem task. It is said that music enhances the learning process. Figure I represent the conceptual framework of the study. Math Problem Solving ability is an aspect of the logical-mathematical and intelligence which could be affected by environmental stimulation such as the presence of Baroque music while doing a problem solving task. Gender and mental ability as possible factors that may affect problem solving ability are considered as control variables to eliminate their influence on the dependent variable in the study. The Problem Research What is the mean pretest score of the group exposed to Baroque music in the problem-solving task? What is the mean pretest score of the group not exposed to Baroque music in the problem-solving task? What is the mean posttest score of the group exposed to Baroque music in the Math Problem Solving task? What is the mean posttest score of the group not exposed to Baroque music in the Math Problem Solving task? Is there a significant difference in the mean pretest scores between the groups exposed to Baroque music and the group not exposed to Baroque music? Is there a significant difference in the mean posttest scores between the groups exposed to Baroque music and the group not exposed to Baroque music? Hypothesis The following hypothesis are tested in the study: There is no significant difference in the mean pretest scores between the groups exposed and unexposed to Baroque music. There is no significant difference in the posttest scores between groups exposed and unexposed to Baroque music. Definition of Terms Baroque Music- this term is associated with the era and the set of styles of European classical music which were in widespread use between 1600 to 1750. n this study it refers to the instrumental songs composed by Bach (Hapsichord Concerto in F Minor and Air on G String), Vivaldi (The Four Seasons), Albino (Adagio for Strings in G Minor), and Chopin (Nocturne for Piano No. 9). Performance in Math- this phrase refers to the score obtained in the problem-solving task designed to measure mathematical ability. Gender- refers to the sex of the person whether a girl or a boy. Significance of the Study This study is significant to parents because the results will give the them information how Baroque music can help in enhancing the mathematical ability of their children. Parents will encourage their children to appreciate Baroque music, and play it while reading, studying and doing homework. This also provides the teachers information that music is a powerful tool that they can use in the classroom to promote academic achievement and mental discipline. The intentional use of music in the classroom will set the scene and learning atmosphere to enhance teaching and learning activities. School administrators will know the necessary equipments to produce a better performance from their students. The recommendations made in this research are an attempt to find means and solutions to improve instructional facilities needed in subjects where Mathematics is concerned. Chapter II Methodology Research Design This study will utilize an experimental design to investigate the difference in the mathematical problem solving performance of pupils exposed to baroque style of music and those who are not exposed. The pre-test posttest non-equivalent comparison groups quasi-experimental design will be the method of investigation. This design is illustrated bellow: Group 1 01 X03 Group 2 02 04 The above diagram means that group 1 serves as the experimental group and receives the treatment (X). In this study X will be the baroque music. Group 2 will be the control group and does not receive the treatment. 01 and 02 correspond to the pretest while 03 and 04 correspond to the posttest of the control and experimental groups. Population and Sampling Procedure The total population of the Grade Six pupils of Zamboanga City Polytechnic State College is 34 and composed of only one section. Two groups will be used as respondents of the study, one for control and one for experimental. The assignment as to which one will be experimental or control will be done be random. Total enumeration will be used for the number of pupils in the class. Instrumentation An objective type of Math Achievement Test will serve as the instrument to measure Mathematical performance of Grade Six pupils. This will be administered at the start and end at the experimental sessions. Before the administration of the test the self-constructed Math test will be submitted to a panel of experts.

Writing Tips from Bestseller Fiction Authors

Writing Tips from Bestseller Fiction Authors If you want to accomplish a goal, there is no better way to prepare than to follow the advice of someone who has already reached that exact goal. The same is true for publishing bestselling fiction novels. Although each author has their own process for getting there, here are some indispensable tips from bestselling fiction authors to help you get there faster.Read everything you can lay hands on. I always advise people who want to write a fantasy or science fiction or romance to stop reading everything in those genres and start reading everything else from Bunyan to Byatt.Michael MoorcockThis one is a common tip from multiple authors. You cant be a good writer without first having read whats out there. This applies to books that are in the same genre youre writing, as well as other books that are considered classics in the literary world (theres a reason they became classics). Reading within your own genre insures that you have a good understanding of whats already been published an d what publishers have accepted in the past. Youll also know what readers within that genre like- the types of characters, plots, etc.Protect the time and space in which you write. Keep everybody away from it, even the people who are most important to you.Zadie SmithThe writing life is essentially one of solitary confinement – if you cant deal with this you neednt apply.Will SelfThis concept is especially difficult for many authors, particularly those who have family responsibilities and who write from home. Theres really no good way to deal with it, and lets face it- reading over the biographies of famous authors of the past, you can find many examples of failed marriages and ruined relationships.However, if you dont protect the time and space in which you write, youll likely never get anything written. Interruptions to your creative process can set you back each time they happen, until you lose the moment completely and nothing gets done. This includes online and social med ia interruptions, by the way, which leads us to the next tip.Its doubtful that anyone with an internet connection at his workplace is writing good fiction.Jonathan FranzenWork on a computer that is disconnected from the internet.Zadie SmithBe honest- how often do you keep social media and text notifications on while sitting at your workspace to write? If this is a habit for you (as it is with most people), end it. Beyond the inconsequential social media updates that most of us spend too much time reading, these interruptions are just as bad as offline interruptions. The concept of unplugging in this sense might not be completely true if youre still using a laptop, but at the very least, you should disconnect and unplug from the internet. That funny cat meme or picture of so-and-sos toes on the beach can wait.Always carry a note-book. And I mean always. The short-term memory only retains information for three minutes; unless it is committed to paper you can lose an idea for ever.Will SelfHow many times have you been driving your car or out running errands when an idea for your novel struck? If youre like many authors, the creative process goes beyond the time you spend sitting at your laptop or typewriter- it is a constant thought (obsession, even) in your head. So carry a notebook with you to record these thoughts. Dont trust your memory enough to remember it when you get back to your desk, write it down now (or at least as soon as you pull the car over to the side of the road).Read it aloud to yourself because thats the only way to be sure the rhythms of the sentences are OK (prose rhythms are too complex and subtle to be thought out- they can be got right only by ear).Diana AthillIf your character dialogue doesnt sound realistic, that will be obvious as soon as you read it aloud. When we read words aloud, we go slower and pay more attention to the rhythm of the language, which makes reading aloud a great proofing tool to determine if a section is written wel l.Dont tell me the moon is shining; show me the glint of light on broken glass.Anton ChekhovThis is Writing 101, but writers still tend to forget it. Narration that describes is not nearly as exciting as seeing it through a characters eyes, particularly in unexpected ways. It gives the character more depth, adds deeper levels of metaphor, and sounds new and different to a reader who has read about the moon shining over the lake too often already.You know that sickening feeling of inadequacy and over-exposure you feel when you look upon your own empurpled prose? Relax into the awareness that this ghastly sensation will never, ever leave you, no matter how successful and publicly lauded you become. It is intrinsic to the real business of writing and should be cherished.Will SelfFinally, lets talk about the confidence that is required to finally let someone read your precious manuscript. This part is difficult for even the most seasoned writers because really, it is a process of laying your soul bare (since your heart and soul was put into that manuscript in the first place). Just keep in mind that in releasing your writing to be read by an audience, you will inevitably feel inadequate and overly critical of yourself and your work. Swallow those feelings and give it to your reader anyway. Their reaction will almost always be better than you anticipated.

Functioning Management Essay Example

Functioning Management Essay Example Functioning Management Essay Functioning Management Essay Qualcomm Incorporated: Functioning Management Katie Atkinson, Farrah Mason, Jennifer McMahan, Robert Briones, Nichol Vann University of Phoenix MGT 330; Israr Hayath Qualcomm Incorporated: Functioning Management Qualcomm is an American wireless telecommunications research and Development Company, as well as the largest fables chip supplier in the world, based in San Diego, California. Qualcomm was founded in 1985 by UC San Diego Professor Irwin Jacobs, MIT Alumni Andrew Viterbi, Harvey White, Adelia Coffman, Andrew Cohen, Klein Gilhousen, and Franklin Antonio. QUALCOMM, 2010) Qualcomm’s mission statement is: â€Å"Life, Connected with technology. From the written word, to image and photos, to music, to videos, games, streaming content, and more, Qualcomm is on a never-ending quest to feed the mind. Whether by developing our technologies or partnering with companies who share our vision, were leading the charge in the digital revolution. † (Qualcomm, 2010) The external and internal factors that affect Qualcomm’s four functions of management (planning, organizing, leading, and controlling) are as follows but not limited to; Globalization, Technology, Innovation, Diversity, and Ethics. This paper will review how external and internal factors affect the four functions of Qualcomm, and how managers and executives use delegation to manage the different factors and functions listed above. Qualcomm; Planning and management’s function When planning the future for any company, especially Qualcomm, you must consider internal and external factors. Qualcomm’s sustainability and value to its stockholders is dependent upon the ability to predict future trends in technology, the global environment and maintain its strategic advantage. For example, Qualcomm’s core objectives include expanding the use of 3G technologies in emerging markets (Business Civic Leadership Center, 2006). Realization of this objective requires that Qualcomm be aware of political, cultural and economic factors in the markets they may wish to enter. Internally, Qualcomm must be structured to be agile and prepared to quickly form partnerships in response to developing opportunities. : Like a manufacturer who uses the best quality materials to produce a product, Qualcomm’s most valuable asset is the intellectual capabilities of its engineers. Qualcomm must create a corporate environment that attracts and retains the best minds. Qualcomm is a global enterprise. The corporation is chartered to function in the international development of wireless technologies. Planning to achieve corporate objectives must scan the external horizon on an ongoing regular basis. This corporation cannot afford to publish a five year plan that sits on the self. Executive planners must evaluate what is going on in the world almost on a daily basis and asking the question, â€Å"How does this affect our objectives and positioning? † Intelligence is critical to this process. Information on the stability or instability of governments, financial markets and emerging research is critical to the sustainability of Qualcomm. Qualcomm is in the technology business. The future of Qualcomm is dependent upon the ability to invest and develop products that are compatible with and have an advantage over the competition. An innovator cannot assume that if they develop the best can opener, they will be the world’s leader in can opener sales. New technologies often compete until one becomes the industry standard upon which other compatible technologies are based. Qualcomm has declared that one of its core objectives is the expansion of 3G technologies in emerging markets (Business Civic Leadership Center, 2006). They are heavily invested in mobile platforms that utilize 3G technologies. G technology may be adequate to support the utilities presently needed by a small home based business in Malaysia, but will it be adequate to support explosion of demand as this market becomes more globally aware? Qualcomm planners must position the design of Qualcomm technologies to expand and morph to respond to tomorrow’s expectations. Qualcomm does business in almost every corner of the globe. As a corporation they must be prepared and plan to foster diversity in every aspect. They must foster a corpor ate culture that supports and respects the culture, religion, and ethnic backgrounds of employees, customers, and partners. Qualcomm takes to heart their Global Workforce Inclusion policy. The policy states in part: â€Å"Inclusion and Diversity are at the very heart of innovation. It requires different perspectives to take an idea, perfect it, and turn it into world-changing technology. And it requires an energetic, diverse workforce to come up with those different perspectives. Here at Qualcomm, we find diversity, and the creativity it brings, vital to our success. To this end, we are committed to providing all employees the opportunity to achieve their professional goals. † (Qualcomm, 2010) Qualcomm portrays itself as a responsible global corporate citizen. Cutting edge research and product development is the life’s blood of Qualcomm. Unethical practices that infringe on the research and product development of competitors may be costly and detrimental to the sustainability of the enterprise. Planning to mitigate the potential damage of infringement disputes was demonstrated by the recent settlement with Broadband wherein the two giants agreed to cross license each other’s patents. This agreement protects Qualcomm from future infringement lawsuits that could cripple its development (Sinapse, 2010). Qualcomm; Organizing and management’s function Organizing can be defined as â€Å"assembling and coordinating the human, financial, physical, informational, and other resources needed to achieve goals† (Bateman Snell, 2009). The company called Qualcomm primarily operates in South Korea, where they employ over 16,100 employees. The external factors affecting organizing in Qualcomm are making sure there are enough resources to complete the jobs for the telecommunication devices. Having an organizational structure is the key to internal aspect of Qualcomm, with employing a lot of employees there must be a clear and concise structure of job duties assigned. Another internal factor is Qualcomm grants out their licenses for use of their telecommunication devices. â€Å"Qualcomm also grants licenses to use its intellectual property portfolio, which includes certain patent rights useful in the manufacture and sale of wireless products†. (Thompson, 2010). Qualcomm has stretched globally in areas such as Italy, Asia Pacific, and United Kingdom which reinforces there leadership in the worldwide messaging market. With Qualcomm going globally all employees have to be organized in the supplier chain of sending over the new product to the global areas as well as manufacturing the new product. This new technology was called Eudora, were it allowed different time zones to still communicate. With Qualcomm becoming so innovated, the company created an agreement with the international publishers which allowed for faster product delivery and improved distribution. With reaching out their market globally Qualcomm has become very diverse, by adding this new agreement it allowed the international countries to keep the delivery and distribution more organized. â€Å"Republisher’s customers will now be able to purchase these localized products and receive localized support in the respective countries† (Qualcomm, 2010). With it now being localized to re-publisher’s customers Eudora is also offered in different languages such as Italian, Chinese and Korean. Qualcomm is such a huge corporation that their ethics have to be very structured, and organized. All employees at the corporation are expected to do their job duties with honesty and in an ethical manner. It’s very important for managers to be organized and follow the code of ethics as well as all employees. By implementing a strong code of ethics all employees and managers will know what values are expected from them. Qualcomm; Leading and management’s function What is Leadership and what makes a good leader? Basically, a leader is one who is able to influence others to attain certain goals that must be met by the corporation or department. According to James Kouzes and Barry Posner, great leaders have five key traits or behaviors which make them outstanding at leading others (Bateman Snell, 2009). Those five traits are: challenging the process, inspiring a shared vision, enabling others to act, leading by example, and being generous with affirmations. These traits are always being tested both internally and externally. The people who are being led have many things to deal with in their own lives which require them to juggle an enormous load, between work life and personal life it is enough to make anybody go mad if it wasn’t for effective leadership. Internally a leader must face the issues of budgeting effectively, creating a vision that he can get everyone on board with and the overall morale of the organization. There are many times a leader must put aside his own desires to be able to â€Å"lead by example† and show his subordinates what is best for the company as a whole. All in all a great leader is going to be able to nstill in his workers/followers a sense of ownership in the vision which he created. This vision can is affected not only by the internal factors previously stated, but also by those elements from outside the organization. So examples of external factors are the economy, world events, and the leaders’ personal life. If there is a bad economy he must know ho w to restructure while keeping morale high. If the world faces an immediate threat or, even, something positive that will change how his organization runs, how will he handle the change and lead his people in the same direction? Lastly, personal lives, everybody has them and something always happens that will potentially throw you off course, how do you plan for the worst or the best and keep your organization or department running like a well-oiled machine? The amount of knowledge of the vast array of topics a leader must be familiar with is astounding. They must know how everything from globalization and technology to diversity and ethics affects his organization. Globalization and technology are a huge area for a manager to have a handle on due to the advantages and disadvantages they bring. For example, an advantage technology can bring to a manager and his organization is the ability to serve his clients or customers quickly and more efficiently. The disadvantage is if the manager either doesn’t know of the technology available to him or doesn’t know how to use it properly, the client could decide to change providers due to lack of quality of service. Technology has also made it harder for managers to keep up with the demand. Technology has also affected the kind diversity the workforce can have. So often the baby boomers may be losing out on promotions due to the fact that they do not know how to use the technology given to them, which in turn allows the younger generation to take over their positions. On the flip side, the younger generations, know how to use the technology, may end up stuck at their current position because the boomers, with more experience, are better suited for the management positions. They will just need to have an advisor for things that they are not familiar with or take a class. Ethics has also being greatly affected by technology and diversity. Ethics, basically the theory of right and wrong, has been pushed to the background because of the insurmountable amount of information the manger most learn. Ethics can affect a leader’s role by the way he corresponds with and conducts himself around fellow employees. Qualcomm; Controlling and management’s function When reviewing the controlling aspect of management one should review how revenues are invested, and recognize the importance of the previous steps of planning, implementing and leading (Bateman Snell, 2009). A strong company will invest in its innovative team to plan out future or expected needs, and create viable, efficient and effective solutions to these problems. Pushing forward into new territories helps a company remain on the forefront of their industry, which is highly important in the fast pace business of technology and communications. Qualcomm has the opportunity to continue their innovative steps and continue to hold their established presence in the United States, while expanding to our European neighbors. The ability to properly control the leadership of the planning and implementing process will prove to be Qualcomm’s success. Qualcomm’s established presence as a communication provider prompts innovative thoughts and controlling of company policies that have been implemented. Qualcomm has expanded their presence globally and in doing so have extended their responsibilities for ensuring their company standards are upheld. The creation of operating procedures during the planning, organizing and leading processes allow for thorough monitoring. Qualcomm expresses the importance of controlling company assets by smartly investing â€Å"23% of our gross revenue †¦ into RD (research and development)† (Qualcomm, 2010). The monies invested into planning and implementing or research and development, has provided Qualcomm with the security of being the first to implement new technologies and upgrades to consumers (Qualcomm, 2010). Using Delegation to Manage Delegation is the assignment of tasks and responsibilities and has many potential advantages for managers, subordinates, and organizations. In order to be effective, the delegation process must be managed carefully, defining the goal, selecting the right person, soliciting opinions, providing resources, scheduling checkpoints, and discussing progress periodically. (Bateman Snell, 2009). Qualcomm used delegation by setting up different divisions within the company. Each division is responsible for different factors such as Qualcomm Global Trading Inc (QGT) is responsible for the globalization factor. (Qualcomm, 2010) Qualcomm uses a decentralization decision making process within each division. The decentralized decision making process allows the employees most directly affected by the decision that is made and have the hands on knowledge of the problem or project to make the decisions. (Bateman Snell, 2009). The authors of this paper believe planning is centered on all of the four functions of management. Managers of an organization are to carry out the functions to assist in the organizations growth. Therefore, they delegate and perform the functions of management. The functions the managers are using to delegate are planning, organizing, leading and controlling. They are to make sure that clients are valued by specific planning. They also must contain a certain amount of people skills. The managers are to lead, motivate, and communicate effectively. (Bateman Snell, 2009). Delegation is a critical skill in the effective management of organizations. Qualcomm has used delegating by first separating each function into a division such as Technology (IT) and each division has their own vice-president who does planning and his subordinates do the organizing, leading, and controlling of the different projects or product management. Qualcomm, 2010) In conclusion, to live up to their missions’ statement Qualcomm used the external and internal factors, the four functions of management, and the delegation management style. Qualcomm is now the world leader in next generation mobile technologies, Qualcomm’s ideas and inventions are driving wireless growth and helping to connect people to information, entertainment and one another. (Qualcomm , 2010) Qualcomm uses the four functions of management (planning, organizing, leading, and controlling) to manage globalization, technology, innovation, diversity, and ethics. In this paper you have read how the external and internal factors affect the four functions of Qualcomm, and how managers and executives use delegation to manage the different factors and functions listed above. Qualcomm management style allows them to evolve quicker then the competition and gives them the flexibility to change with the times. References Bateman, T. S. , Snell, S. S. (2009).

Stem Cell Research- Using stem cells from Testes to produce Insulin Research Paper

Stem Cell - Using stem cells from Testes to produce Insulin for Type 1 Diabetics - Research Paper Example There are conventional treatments available but they do not cure the disease. Now, scientists have given some hopes to the disease stricken patients with a new type of treatment with the stem cells. Stem cells are found in different tissues. They develop and divide into many other types of cells especially in the early age. The self-reproductive stem cells serve to repair damage tissues. When a stem cell divides, it might remain the same type or becomes a specialized cell e.g. a brain cell. Until 2006, Scientists were mostly working with â€Å"embryonic stem cells† and â€Å"Somatic or Adult stem cell†. Now they have learned to alter special cells genetically and use them for special purposes as a stem cell. The regenerative property of a stem cell opens new venues to explore and may find permanent cure for diseases like diabetes. Recent research at Georgetown University shows that stem cells from human testicles, which produce sperms, can be genetically programmed to p roduce insulin by transplanting into the human body. Clinical experiments indicate a lower amount of insulin produced by this method and researchers are pondering to find a way to bring it to a required level. Just like any other transplant, if the organ is donated by someone else, body takes it as a foreign intruder in the system. The immune system immediately tries to stop it from proper functioning. To reverse the process, a patient has to take immune-suppress medication for the rest of the life. In an effort to offer resistance to the newly implanted cell, immune system destroys the original beta cells. Since cells that are being transplanted, are extracted from the same person so the body does not perceive them as foreign agents. After removing cells from testes, also called spermatogonial cells, placed in a specially designed media where they are chemically changed to produce insulin like beta cells. In other research programs, Induced pluripotent stem cells (IPSCs), artificia lly derived from Adult cells and changed by inducing forced genes and proteins to act similar to embryonic stem cells. Thr artificial method to program IPSCs, pose serious threats to introduce cancerous tissues in the body. But the new research in 2008 indicates the possibilities of stem cells in curing diseases. Scientists have disclosed a technique to separate the oncogene, largely cause cancer, from pluripotent cells after their transplantation. A new approach, yet to test on humans, of generating IPSCs cells by injecting proteins might be suitable for therapeutic use. Adopting this new technique eradicate the need of genetic alteration. The ongoing research at Georgetown University focuses on finding a treatment for type-1 diabetes in which cells are persuaded to function like IPSCs. The threat of tumor ‘teratomas’, may destroy the newly formed insulin cells. Another concern is the elimination of alpha cells which produces ‘glucagon’ with the beata cell s. Glucagon becomes active when the sugar level drops to a certain level and may cause death. In order to find a commplete remedy from Type-1 diabetes, researchers are looking towards a readily available source of spermatogonial stem cells (SSCs). SSCs are derived from testicles and not required to add new genes. These cells show similar characteristics to that of beta islet cells. The scientists successful in lowering the glucose level after planting these cells into diabetic mice, showing that enough insulin is
