The reaction between zinc and copper sulphate Essay Example for Free

The reaction between zinc and copper sulphate Essay I am going to investigate the reaction between Zinc and Copper Sulphate. Method The reaction will be exothermic; so that means heat will be given out. I will have to see the temperature difference between each amount of Zinc and store the results onto a graph. The equation for this reaction is: Zinc + Copper Sulphate Zinc Sulphate + Copper. Copper Sulphate is a blue solution, which is toxic, and the Zinc steals the Sulphate (like a bully taking sweats from someone) and that leaves Copper as a solid form. This reaction occurs because Zinc is higher up the table in the reactivity series; I know this because I referred to the textbook. Prediction My prediction is that I think that the Zinc will react quite quickly with the Copper Sulphate. It will make the temperature rise and turn into a colourless solution; the temperature will rise by about 20i. There will be no things to make the test unfair, I will make sure the same cup is used each time, the amount of Copper Sulphate stays the same (40 ml) and the amount of Zinc is correct each time. Safety For safety during the experiment I will make sure that I will wear goggles so I have eye protection. I will make sure the solution does not get poured down the sink because it kills bacteria that the sewage workers produce. Also I will make sure the laboratory rules are followed accurately. Results table Mass of Zinc Number of moler ratio Temperature Temperature Temperature Moles of Zinc At the start At the end Increase Analysis Ive analysed my results and the shape of the graph is steadily inclining except for the one anomalous result. The result depended on four things the temperature, catalyst, concentration and size of particles. The temperature was slowly rising until the zinc stopped reacting. The catalyst (zinc) made the reaction happen easier so the activation was lowered. The anomalous result had a few explanations for why it was lower than the others. Conclusion I have learned that the experiment was exothermic and the rate of reaction with zinc and copper sulphate. Also that zinc it higher in the reactivity series than copper thats why there was a reaction otherwise there would not have been no reaction at all. The zinc acted as a catalyst in the reaction by speeding up the reaction so it was less activation. Evaluation The method I used in this experiment was displacement, were the copper sulphate and zinc reacted to produce zinc sulphate plus copper, so the more reactive metal (zinc) displaced the less reactive one (copper). During the experiment I have found out that the experiment I carried out was similar to my prediction that made except for one anomalous result. The average temperature raise was 19. 5 and my prediction was 20. It probably would have been higher if the anomalous result was higher that 13. The only reasons for the anomalous result was either because I didnt let the temperature drop from the previous experiment or I didnt let it go to its maximum temperature before ending the experiment. So my prediction was nearly all correct except one result that made the average lower and the line of best fit on the graph decrease.

Examining the different disciplines of forensic science

Examining the different disciplines of forensic science Forensic science provides a form of applied science contextualised with the law, à ¢Ã¢â€š ¬Ã‚ ¦inextricably in the service of the public.1 However, increasing publicity through visual media that glorifies and deceptively portrays the field as fool-proof, is having negative impacts in courts worldwide. These impacts are largely due to incorrect protocol and overstating of results beyond what the jury can comprehend. Mystery and awe has surrounded forensic science, captivating audiences with programmes such as CSI: Crime Scene Investigation. The series of forensic-related footage has enabled the field to become known widely, however understanding the complexities is being shown to be a serious constraint. The advantages have seen the industry receive large grants and funding in some areas, however the majority of juries misinterpret the strength of evidence, easily overestimating the weight it offers the court. This is significant as the jury is typically made up of everyday people, r ather than scientists. Therefore, further transparency is needed for the jury to interpret the weight to apply to various types of evidence. It is apparent that the multidisciplinary science of forensics is lacks the appropriate strength to govern the entire framework under a common model; forensic science. Whilst there have been huge amounts of research into the chemical , biological and physical sciences, many of the evidences, such as tool mark and fingerprint evidence, that are relied on to provide individualisation and uniqueness lack adequate funding and research to develop their validity, reliability and statistical significance. It is a flaw in the system that we are required to comprise the entire variety of disciplines that interpret forensic evidence under one umbrella-like concept. Encompassing the forensic disciplines under the one term is the result of rapid expansion in the field. It is appropriate to appreciate that some fields, particularly areas of DNA research, have received significant attention, where others have been neglected. Perhaps forensic science and its community are at a stage where disciplines can be distributed between what is forensic evidence and what is forensic intelligence. Or perhaps it is more suitable to divide on the basis of scientific / analytical based or expert interpreted. Forensic science as a whole needs to be thoroughly evaluated to determine an effective distinction for the legal system it is meant to benefit, where the absolute science can be provided solely on the condition that there is reliability, validity, and known uncertainties, while the interpretational evidence that cannot be substantiated with statistics and databases, yet can potentially be validated with further research to assist individual experience of so-c alled forensic experts. The National Research Council of the National Academies has identified in the United States the significance of the overestimation and misinterpretation regarding the forensic evidence that is being produced for the courts.2 Their report dissects the major disciplines, establishing recommendations for strengthening forensic science, including but not limited to establishing stringent protocols, better definition of expert witness phrases and implement and enforce better practices and standards for forensic science professionals and laboratories.2 This report will not examine in detail each discipline of forensic science. However, it is the poor attempt of classification of all forensic practices into the one structure of forensic science that will be the focus. Forensics and the CSI effect Forensic science evolved from the need to prosecute criminals more effectively. Criminal activity occurs in many facets, and can occur at any time.3 Illegal activity can also be promoted by drugs which is both dangerous for the criminal and people around them.3 Crime scenes, whether physical harm have occurred, or just simply theft, are usually rich in biological and physical information which, if interpreted correctly, can allude to the events that occurred.3 The processes and people whom this information was handled between, from the collection to analysis, to the use in court as evidence, is known as the chain of custody. If this chain of custody is not maintained with the highest integrity, the information gathered has no use in court. Often carelessness and poor decisions from handlers lead to potential evidence being reprimanded. Each time forensics fails in court, it adds to the pressure of sceptics who criticise the entire field because of the encompassing of all forensic sci ences under one domain. It is the Hollywood glamour that has given television programmes associated with forensic science an established excitement among viewers for their 60 minute showcases. The episodes make forensic science appear deceptively simple which invites illusionary expectations of analysis and value at trial. The CSI effect does not replicate the true intricacies of real forensics. Whilst the digitised world is a real thing, it is greatly overstated the power and graphical interfaces of the computer systems used, tapping into databases that are only dreamt about by certified forensic experts. It is then a false assumption that everyday forensic analysts are assisted with these capabilities. It is examples in these shows such as fingerprint comparisons that search through computer databases in minutes, and DNA samples that are analysed for STRs and specific loci by the time they arrive back from the crime scene. In reality, DNA analyses are backlogged in many cases because of the time it takes to analyse. In reality, simple PCR amplification can take the time that one episode of CSI establishes, develops and solves an entire case. The effect broadcasting has had in portraying the dramatic evolution of criminal cases also has confused the role individual forensic experts have, that is, to assist law enforcement in establishing a case, and then to assist the court to understand and interpret the evidence and their findings. The CSI effect has led people to believe they also take on the role police investigators, and even lawyers and counsellors in some instances. This CSI effect has extended into the court room where the jury are potentially faced with this expectation that the evidence that is going to be explained is decisive. Unless the expert makes it absolutely clear with the significance of the evidence, the jury can add substantial weight to the case, on some occasions be the fundamental basis of their decision. It is up to the defence to cross-examine expert witnesses and source potential mishandling that can question the evidence. Once questioned, the integrity of the case is in jeopardy due to misconduct. Many wrong convictions have been made on evidence that has been incorrectly examined and weighted. Every time forensic science fails in court, the pressure is placed back on the entire field to argue the truth behind the science. The problem extends not only from poor expert witness testimony skills, but an inadequate framework with which the system is explained. Strength of Forensic Science Encompassing the many disciplines that currently make up the forensics framework within one title lacks the fundamental strength that is needed to maintain the integrity of applied science for the benefit of the public. A model should essentially provide the basic theory for all disciplines it governs. This is not the case as we begin to dissect this concept. The first basis of which the current framework of forensic science does not adequately distinguish between the disciplines is the misperception of differing areas of science, being pure and applied. Science can be described as a body of à ¢Ã¢â€š ¬Ã‚ ¦knowledge or a system of knowledge covering general truthsà ¢Ã¢â€š ¬Ã‚ ¦concerned with the physical world and its phenonomen.4 With this understanding, it is clear that when combined with the context of forensics, the overall concept of science should be contextualised with the legal system.1 The variety of natural sciences, such as chemistry, biology, and physics have be around for decades and their theories, methods and techniques have been strongly developed. It is the disciplines that have evolved out of necessity for law enforcements requirement for further evidence, such as fingerprinting, tool mark impression and document examination, which do not have the established literature and research.8 James and Nordby (2003) consider th is, pointing out that natural sciences are based on theory and are controlled and certain, whilst forensic sciences are practical, applied, uncertain, and compromised. This view does not consider the human interface that science is controlled by, and that the flaws of science are generally the flaws in the procedure and protocol used. Whilst in many cases what James and Nordby (2003) observe is true, it is the professionalism that accompanies the process which determines whether the integrity is maintained. James and Nordby (2003) contradict themselves to agree with the above, noting that Good science, and good forensic science, produces reasoned opinions. This truth of this statement is derived from the procedures used by individual scientists to derive their opinions. The quality of the scientists analysis ensures the validity of their opinion, accounting for both natural and forensic sciences. A second delusion of the current framework has caused non-scientific evidence being cunningly used as trickery in the courtroom. It is dangerous that the courts, since admitting evidences such as CCTV footage, are leaving the defence to discredit the opinion evidence that has blatantly no scientific theory behind it. This report will not be used to argue the reasons other than that disciplines such as document examination, fingerprinting, profiling, and facial mapping are significant forensic intelligence for law enforcement, and are often used to establish a list of suspects. However their use is currently limited by the research and funding that has gone into their development, and until analytical and statistical significance is analysed for each discipline, they should be not collectively assigned within a broad forensic science framework. When evidence is presented in the courts, it is often seen that the applied sciences come undone from both the lack of foundation of the disci plines, and poor forensic expert testimony. Starrs (2003) is mindful of the relationship between lawyers and forensic practitioners, conscious that forensic scientists often struggle with the legality of the courts.11 To contrast this, lawyers are identified to narrow-mindedly focus on discrediting scientific opinion, due to their insufficient knowledge of science.11 Starrs (2003) comments that the contrasted view of science and the law requires experts reconciliation so that they can work in both amicably and advantageously. An example of the injustice that expert witness testimony is causing is demonstrated in the Atkins v The Queen trial. The facial mapping discipline is not a direct science. It has developed out of the need for visual identification from video and photographic evidence. However, because judges, jurors interpret faces of known and unknown people every day, there is a misconception that the area of expertise is more simple than uncommon knowledge, such as DNA analysis.5 Potential prejudice and miscarriages of impartiality due to underestimating the difficultly in establishing identification by facial mapping is now commonly evident in courtrooms due to the increasing footage of CCTV and other photographic material that is being submitted as evidence.5 In the example Atkins v The Queen trial, the expert witness that testifies only similarities between the exemplar and the captured footage of Dean Atkins failed to inform the discrepancies into their testimony.5 It is believed that the jurors understood the expert opinion as a positive identification. It is a known fallacy that jurors cannot weight appropriately the evidence that is given to them, and therefore it should be made clear what basis the opinion of the evidence is made. Also, there are ways to mislead the jury into thinking that there is science involved. Establishing scientific-like terms such as the Bromby scale, in the Atkins v The Queen case, should not be used as forensic evidence in the court room as the courts are not the place for experts to sit and testify indecisive opinions. The use of expert opinion established on experience rather than the science needs to be frowned upon, and should begin to discredit users from being professionals. An alternate example is the Brandon Mayfield case. Mayfield was arrested in March 2004 as a material witness in an investigation into the terrorist attack in Madrid, Spain, on commuter trains. It was found by the FBI using IAFIS that it was Mayfields fingerprints that were left on the bag of detonators. However, the Spanish National Police later informed the FBI that the fingerprints were in fact from an Algerian national as the source. The misidentification from the Brandon Mayfield case was due to many factors such as bias, prejudice, human error and insufficient methodology .6 While the automated approach to fingerprint analysis is mostly sufficient in establishing a collection of suspect fingerprints that have similar markers, it still requires human interpretation to establish which fingerprint has all the same individual characteristics as the sample print. For this reason, it is essential that if such evidence was to be admitted to court, the jury is aware of this, and other, types of error, and that the expert evidence should be used to aid other evidence. While fingerprint evidence does have noteworthy research it should still be considered by juries carefully. The technique relies of observation of markers from experts rather than analytical techniques that can be verified and thus, should be considered under an alternate framework. Fingerprint analysis is a discipline that has received more attention than facial recognition and many others, however, it is essential that a strategy is implemented to amend the framework strength that forensic science is lacking. At third concept that prompts further debate is the misuse of the term science in forensic science. It is observed that society perceives that science provides à ¢Ã¢â€š ¬Ã‚ ¦hard facts, definite conclusions, and uncompromised objectivityà ¢Ã¢â€š ¬Ã‚ ¦ in every case.9 Due to the rapid expansion of forensic science, the definition has not adopted its use today, where research provides methodology. Then it is perceivable that forensic science is the use of these methodologies in the search for facts, although the result may not always provide the statistical significance. This is reported by Starrs (2003) to be the key issue with forensic science. Starrs (2003) observed the public portrayal of forensic science needs to capture à ¢Ã¢â€š ¬Ã‚ ¦a more realistic scientific levelà ¢Ã¢â€š ¬Ã‚ ¦ so that juries wont measure up expert witnesses and their testimony based on expectations far beyond the scope of the forensic framework.11 It may be that forensic experts are struggling to keep pac e with the growth of forensics and public misunderstanding, and are expressing opinions that are greater than the significance of their results.11 As Inman and Rudin (2001) explained, in many cases science becomes a misused term, employed to gain credibility and legitimacy in society.9 It is important for the future of forensic science that the understanding of the science body is clarified, being that science provides process rather than truth.9 Clarification can be assisted by the observation of the continual evolution of science, where at any point of time a discovery enhances the knowledge we have, and refutes (or refines) what was once known to be true.9 Potential frameworks A framework is an à ¢Ã¢â€š ¬Ã‚ ¦underlying set of ideasà ¢Ã¢â€š ¬Ã‚ ¦that provide the basis or outline for something intended to be further developed at a later stage.7 To encompass all forensic disciplines, developed and undeveloped, under the one forensic science framework is misleading, particularly when justifying evidence in court. It has been discussed through auditing the strength of forensic science by the National Academy of Sciences, many forensic science methods have been developed due to the evidence that has been able to be collected from the crime scene.8 Whilst it is known that many disciplines, such as serology, forensic pathology, toxicology, fingerprint analysis, and chemical analysis have a solid backbone regarding their theories and methodologies, there are many facets that are not as well developed.8 These include pattern / impression analysis, firearms analysis, hair and fibre analysis, handwriting and document analysis, explosive and fire debris analysis, for ensic odontology, blood spatter pattern analysis, paints and coatings analysis and many more.8 Inman and Rudin (2001) agree with this concept, in that The realm of science can be divided into pureà ¢Ã¢â€š ¬Ã‚ ¦and applied science.9 Their approach highlights the need for science disciplines to be distinguished. However there are potentially many errors is segregating on the basis of pure and applied sciences. For example, analysis of forensic analysis of crime scene evidence relies on the foundation on the pure or natural sciences. Therefore, at what point does an applied science be sufficient to be classed as a natural or pure science? Potentially, there are a number of possibilities that could divide disciplines adequately for the use of expert evidence weight in courts. Some of these include: Forensic evidence vs. forensic intelligence Analytical vs. interpretational Scientific vs. intuitive Objective vs. subjective In a forensic context, forensic evidence and forensic intelligence seem the obvious option. However, exploring into how each are defined establishes that much forensic evidence assists also as forensic intelligence and vice versa. More appropriately, objective and subjective establish the specificity required for absolute classifications. Forensic evidence with a scientific approach could be defined as the objective analysis while forensic evidence with an interpretational approach could be defined as the subjective analysis. Correlating this idea, Inman and Rudin (2001) suggested that objectivity of science is always being sought after, realistically, we must understand that human interpretation of evidence, à ¢Ã¢â€š ¬Ã‚ ¦regardless of whether the items of interest are two fingerprints or two spectraà ¢Ã¢â€š ¬Ã‚ ¦, places subjectivity into the equation.9 Whilst this is true in this day and age, the reality is that technology is developing exponentially to the point where automated systems will replace much of the bias that evidence is faced with. A framework that adheres to this objective and subjective system would be able to provide evidence weighting guidelines for the significance between these two types of forensic analysis. Potentially, jurors could then differentiate forensic evidence based on this system and already for-see pragmatic value for a fair trial. It must also be recognised here, that due to method and protocol refinement from continuous scientific research, it is important for regular auditing of each discipline to establish the type of analysis that fits best for the time. By having an appropriate framework employed, CCTV footage and other photographic medium that is being used as evidence, would shift the onus back upon the Crown to demonstrate evidential value. The Crown would then be required to demonstrate the convicting expert opinion has à ¢Ã¢â€š ¬Ã‚ ¦probative valueà ¢Ã¢â€š ¬Ã‚ ¦ by exposing its reliability and validity.5

Demand and Supply of Gold in India

Demand and Supply of Gold in India Demand is the relationship between price and quantity demanded for a particular goods and services in a particular circumstances . For each price the demand relationship tells the quantity the buyers wants to buy at that corresponding price . The quantity the buyer wants to buy at a particular price is called the Quantity Demanded. supply is the directly proportion of price when the price of the commodity is increased then the supply of that product also increase or visa- versa. ON THE BASIS OF GOLD COMMODITY:- In the relation of gold the demand cannot affected or doesnt matter of price, demand and supply because it is luxurious product and they always usable for functions and many of areas. The price of gold is increases demand then the demand and supply also occur in positive range. The term can be movable as follows:- When the price is increases then the demand and supply can movable in upward direction. When the price is decrease then then the demand and supply can change because the demand is high and supply will be decreases in range. The main concept is started from here to analyze the demand and supply of gold in India. The price is the main factors which can be changing whole style of product sale in the market but gold is a luxurious product and the price does not matter there they r directly based on the willingness to buy the products. This is analyze on the basis of previous data when the price is 17000 rs. In india and what about the demand and supply of the gold in market this will shown as follows:- It schedule is rougly showing to how the relation between price , demand and supply that will be arises on same direction this is only for gold product not for other . It is the concept demand curve is always downward slope and the supply curve move on upward . it means when the price of commodity is increase then demand is decrease and the supply is also increases but in that condition the demand and supply moved in same proportion . THE MAIN OBJECTIVE OF GOLD DEMAND AND SUPPLY ARE AS FOLLOWS:- When the price is automatically increased in year 2005 then the consumers are simultaneously struggling. In present time the market price of gold is 19,171 Rs. Per 10 gram , after hitting a record high of 19,257 rs. Earlier in next week. In the time of festiwal the price is increase then the consumer is struggling to buy but in small range capacity. Basically in the seassion of dhanteras , diwali the demand of gold is high and the consumer can buy without any price problem. BRIEF DISCRIPTION ABOUT HIGH PRICE CUT DEMAND:- This condition doesent seen in the gold market because when gold was a barbarious relic the gold price stood at just 12000 rs. In that condition the various changes are coming in the gold and silver market according to as follows:- A CHANGE IN THE NATURE OF THE GOLD INVESTORS JEWELRY At the turn of the century , the jwelery and industrial gold buyers , alongside rural , agicultural Indian demand, dominated the gold price. In a developed country the gold was not bought for itself and its importance. That condition the major role basically in jwelery, often the cheaper part of piece of jwelery. in that time the prices cannot rises in that much, in that condition the gold price is high .it means when the price of gold is high then the buyers are low. The buyers are still there, but they want in small volume or range due to high price of that commodity. In that condition the market are focuses in middle class person to increase the capability power and creat high growth INDIAN DEMAND When they targeted to middle class family to increase the demand in that level of customer mind to focuses in that level of customer. The market wants to increase the efficiency and they also aware that gold is traditionally valuable in india and they aeare that customer can easily brought due to the need and knows the condition of market. After that marketers can expect that the price of gold is higher then doesnt affect in that market strategy because it is the investment terms which is basically effort by Indian customers. They always analyse that when the price is high then it affect in supply terms. WESTERN JEWELRY , COIN AND BAR DEMAND According to the analyser to analyse that in tradition the gold market cheap jewelry basically invested in to coins and small bars is and they analyse to investing in that areas of Indian market.the Demand ofr gold is always protect the wealth andprotect the mony market loss to maintain and equal balance generated. The marketers also seen the quantity and quality of demand dropped initially, as jewellery demand always decline or down faced in the market but is now gathering pace and actually increasing on both fronts, especially if the marketer add the small coin and bar demand to it then the gold moves up the ladder of exclusively and expensive decorative items again higher quality gold jwelery demand (accepting high prices) is growing again. At the last the marketer seen that the demand of jwelery is always increases. And generated high efficiency in the market. 2. A WIDENING IN THE NUMBER AND SIZE OF GOLD INVESTORS GOLD EXCHANGE TRADED FUNDS The size of the market is high and large number of investors in the market and always want to increase the return in future trend. In the modern changes the market price of gold is always high but no effect in the consumption power they always choosen gold and buy for future trend because it always slope in downward. There are so many factors which changes the consumption and buying power of customers the main factors are as follows like income and price . the price of gold is simultaneously increases but demand is also movable in same directions. CENTRAL BANK The story of central banks and gold is a sad one. As both politicians strove to establish a doctrine that paper currencies, with no gold backing, better serve as money then gold does. By persuading people that central bankers were capable of being a satisfactory and the gold was a barbarous relic that had no place as money, they sanctioned dual policy of selling and sidelining gold as mony and accelerating the supply of gold to the point that the easy gold picking were exhausted . now central banks have had to revert to their underlying belief that gold is a vital reserve assts , particlurly when drems fade and realities take over . Higher price in their case have led to a cessation of sales and subsidential buying. SWITCHING FROM OTHER MARKETS TO THE GOLD MARKET As a gold and silver prices rise just like a thermometer measuring global financial uncertainity and instability , more and more investors are ntering these markets for the first time, not for profit . , but for protection against such fears and in an attempt to preserve the wealth they have. These investors come from the entire spectrum of investors across the length and breath of our world. This is the quintessential reason why demand for gold will rise as gold price rise. WHY ECONOMISTS USE ELASTICITY Elasticity means degree of level changes in the particular commodities is called elasticity But here, we are discussed about changes in the demand and supply of gold in demand and what are the various tools to find out the degree of demand of gold in india. THE BASIC USE OF ELASTICITY IN ECONOMISTS AS FOLLOWS:- Economist wants to compare gold demand all the times. Is gold demand more price sensitivity then silver demand . Is the supply of gold is equal. An elasticity is a unit- free measure. By comparing market using elasticity it does not matter how we measure the price or quantity in the Indian market. Elasticities allows to identify the differences among markets without standedizing the units of measurement. THE ELASTICITY OF DEMAND MEASURE BY AS FOLLOWS:- PRICE ELASTICITY OF DEMAND INCOME ELASTICITY OF DEMAND CROSS ELASTICITY OF DEMAND PRICE ELASTICITY OF DEMAND Degree of level changes by the price of commodity . the gold commodity is directly not affected in the demand because it is a luxurious goods. According to the gold the descriptions are as follows Gold price have been rising this year and this is the news that dominates in newspapers . The last time gold prices rise at such pace was in 1980. In fact gold price never touched the hights they had reached in 1980 and in fact were at their lowest in he year 1999. The first point is to be noted is that both gold and oil prices move in together . both were at their highest in 1980 and while oil has become far more expensive that it ever was , gold prices still not a very high compare to where they were in 1980. The prices are taking in high price adjusted for inflation and not the nominal prices that we see going up year after year. SECOND POINT to note is that gold prices elasticity is negative . Higher the price of gold, higher is the demand for gold. This is a unique feature of gold , as many other commodity whose prices go up sees lowering of demand . When prices rise the most that the demand is the highest, pushing up prices further. In the year 2007 , gold prices went up by nearly 20 % compared to price in 2006 . Demand for gold went up by nearly 5 % . when people say prices goes up , they normally tend to consume less of the good, including essential items like oil and petrol. The nominal price always stay above the previous price, therefore gold is never seen as a risky investment compare to real estate, the share market and the money market. Gold is a unique metal . it has been the most attractive metal for thousands of year. The roman empire and the Egyptian civilization were known to have used gold more then 2000 years ago. India is a growing primarly country because of income growth in the country leading to higher purchases of jwelery . When the recession subsides and the industry looks up and real estates prices rise again gold price should come down from the heights they occupy today. SO GOLD IS SAFE INVESTMENT ? THE ANSWER IS CLEARLY YES. AS gold prices do not come down in nominal terms . however as the economy improves and other forms of investment become attractive , the return on gold come down drastically and may sometimes in real terms become negative . however jewellery has a sentimental value attached to it too, therefore even when price come down , people remain proud of their gold purchases . Buying gold makes sense during the time the rest of the economy is receding, but when economic growth and industrial growth is handsome . like in india now, investing in gold might deliver the lowest returns that one could have obtained . however , this return is in all likelihood is risk free, therefore it makes sense for those who like to avoid risk . it is important to remember that usually higher the risk , higher is the rate of return for any investment. At last it is simply explain that the price of the commodity is increase then the gold is not affected because it is type of investments in the market and always given positive return . so it is future profit generated investments which is always given better and high return to the customers. THE MAIN ADVANTAGES OF THE GOLD AND NOT AFFECTED PRICE AS FOLLOWS:- THEY ALWAYS GIVEN POSITVE RETURN TO THE BUYERS IT IS THE INVESTMENT FOR FUTURE BENEFITS THEY ALWAYS GIVEN POSITIVE GROWTH PRICE IN THE MARKETS. THE PRICE CAN NOT AFFECT TO BUY THAT PRODUCT. INCOME ELASTICITY OF DEMAND As a persons income rises , he or she can buy more goods at a given price at any particular time . but the ability to buy more goods does not necessarily imply the willingness to do so . It means when then the consumers income is rises or dicreases then directly affected to consumption capacity. If the demand of the goods rises as income rises, then that good called a normal goods . Also the demand for the normal goods falls as income falls . the demand for a normal goods and incomes are directly related. The demand for a inferior goods income rises and good falls . the demand for an inferior goods and income are inversely affected. SOME IMPORTANT ASSPECTS WHICH AFFECT INCOME ELASTICITY OF DEMAND AS FOLLOWS:- PREFRENCES:- Peoples preferences affect the amount of good they are willing to buy at a particular price. A change in favour of goods shift the demand curve rightward. But in the gold commodity the income is doesent affected because the always show when the consumers income is rises thend the demand is also increases and visa versa because it is a investments which wa BENEFITTED FOR FUTURE. NUMBERS OF BUYERS:- The demand for a goods in a particular market is related to the number of buyers in the area . The more buyers, the higher demand , while the fewer buyers , the lower the demand . EXPECTATION OF FUTURE PRICE:- Buyers who expect the price of the goods to be higher next month may buy the good now thus increasing the current demand for that particular goods. Buyers who expect the price of the good to be lower next month may wait until next month. POPULATION :- Large no. Of buyers are in Indian market the customers and population are so high in Indian market . Examples:- india have created so much demanded for goods and services because of its massive population. ADVERTISING:- An increase in a firms effective advertising will be cause in demand for the product being advertise. For examples :- Indian have been buying gold for the last few years . however, there is no another addition cost are included in that luxurious good. CROSS ELASTICITY OF DEMAND It means when the price of the substitute commodity is increase then the other product is dicreases and visa versa . there is two commodities in iindia is silwer and gold . When the price of the silver is dicreases then the silver commodity is increases and gold price is dicreases then the demand of that commodity is increases. Now the bullion banker is net short gold when he conduct this operations . remember he borrowed gold and now he has a financial assets . he is making 5 % return on the spread , but he now has a gold price risk . as a banker he is not normally business of putting on speculative positions . so basically, in doing this operation but bullion bankers has a hedged the gold price and he takes a small margin- like a half of %- from this intermediation . in doing so , he allows private market participants to go short gold . thats why we elide the two phrases- going short in the gold market and gold borrowing . the ultimate borrowers in the gold leading operation are these shorts in the gold future and forward markets . Now we have a conservative set of gold leading number and we have a more aggressive set of such numbers . our range of estimates emplies that somewhere between 10000 and 16000 tonnes of the official sector gold position has left thse results way of leading the process . TABLE 1 : WHY OFFICIAL SUPPLY/DEMAND EXCEEDS MAJORITY OPINION ESTIMATES AN ARGUMENT FROM THE SUPPLY SIDE Total Gold Loans Outstanding  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚      BOE GFMS December 1993 4,750 1,600 June 1995 9,250 2,200 Note: All Quantities in Tonnes  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   This discrepancy was so large that tried to be conservative and for no good reason, chopped the 9000 tonnes down to 6000 tonnes because that 6000 tonnes figures was already so far removed from the official numbers . in any case , this bank survey implied big , big errors in the consensus supply/demand balances and half of a lot more gold lending than anyone thought . Now look , gold lending began in earnest in the early 1980. By 1995 it was a process that had been going on for more than ten years . now, what if there were 6000 tonnes of gold loans not 2000 tonnes of gold loans as implied by the consensus supply/demand statistics . that mean that there had been 4000 tonnes more lending , most of it over the last ten year period . gold lending was a small activity during the 1980 . it was a much bigger activity during the 1990, so obviously it was a business that was occurring on an increasing scale . if the discrepancy was 4000 tonnes over 10 to 15 years , 300 to 400 tonnes a year well , then it was probably 200 tonnes a year in the 1980 and it was probably nearer 600 tonnes a year by 1995. That mean supply and demand were underestimated by something like 600 tonnes a year . If we total these three demand items we arrive at the following:- Table 2 Metric Tonnes    1999 WGC gold demand for jewelry, bar and coin in 27 countries 3,282       GFMS gold jewelry demand in an additional 7 countries 1) 268       GFMS global demand in all other uses (excluding jewelry, bar and coin) 458       Incomplete Global Demand Subtotal 4,008 GFMS Global gold demand 3,9852) GFMS occasionally report and use demand . there survey for 1998 including the estimate used here . there was no comparable estimate in their 1999 report . the WGC reported a large increase in global gold demand in 1999. Base on wgc glbal demand for trend this number is probably conservation . GFMS total gold demand exceeds this total by 170 tonnes . they attributes demand to investigate in india . From the above it is clear that the WGC survey plus select additional item from the GFMS points to a total that exceeds GFMS estimation of global gold demand . this subtotal still excludes jwelery demand in more than 100 countries. It also excludes official coin and bar demand in these 100 or more countries as well as seven additional countries mentioned above. It is basically helps to understand the total demand and supply of gold in india and they are basically helpfull for searc what r the condition can not decrease the demand and supply of gold in the market. It always search and analyse the terms and conditions which help to easily find out survey of gold in india or many countries. ANALYSIS OF DEMAND AND SUPPLY OF GOLD IN INDIA The ever increase of demand and supply of gold in india , various hypothesis have been put forward from time to time:- Demand for gold has an autonomous character. Supply follows demand. Demand exhidits income elasticity , particlurly in the rural and semi- urban areas. Price differential cretes import demand , particlurly illegal import prior to the commencement of liberalisation in 1990. A part of the demand is caused by the need to stash away uncounted wealth and income. Gold trades figures since the onset of liberalisation in 1990 shows that while the price differential narrowed from a high of around 53.1 % in 1991 to about 5-10 % currently the import volumes rise unabated. Gold demand in india increased by an annual compound rate of around 15 % from 1990 to 1998 during the period of liberalisation with growth slowing thereafter. This was high , not only visa- versa the world demand growth rate of 3.05 % but also in relation to the trend Indian . GDP growth rate is 5.5 % and Growth rate demand for oil is 3.8 % Energy and sugar is 6 and 5 % Gold imported officially for domestic use is now channelled almost exclusive via the official agents or the authorisd commercial banks. Some aspects which helps to anlyze the gold demand and supply in india.:- FUTURE TRENDS :- What is likely demand trnd for the future? Given the fact that gold demand is income-elastic, it would be safe to assume that demand will increase over the next decades. Since gifting jwelery at the time of marriage constitute the major components of demand, ball-park estimated could be on the basis of the no. Of marriage that takes place actually. On the basis of assumption around 8 million marriage r held in india per year. Gold is required for marriage by families of different income groups. GOLD MARKET IN INDIA:- The gold market in india is predominantly a market for buying and selling physical gold. In the whole sale segment, nominated agencies are the bulk importers. This market is resonabily efficient from the point of view of distribution of bars and scraps over the length of the country which takes place in a very efficient manner. Price manner is also generally observe in areas with identifical of duties and taxes. Gold leasing volume are small in comparision of physical buying and selling. Most of leasing activities taken by nominated banks on a back to back basis via supply from overseas. The market needs to develop for at leat two reasons:- To provide working capital at low cost together with gold price leading,not only to the exporter but also to jwelery manufacture for the domestic market. The existence of gold leading market is pre-condition for arbitrage free pricing of gold forward in the local market. ISSUE FOR THE FUTURE :- It would only be logical to assume that the neeed for a review of the overall policy stance with regards to gold is now being increasingly felt in official circles. As with other areas of liberalisation , the direction of change will certainly be positive, although it would be difficult to imagine any specific time frame. However the following issue are like to be the focus of policy.:- Strengthening of the infrastructures and market in physical gold. More assaying, refining and recycling capacities of international standard and accreditation are expected. Better protection for consumers, by way of the spread of hallmarking of jawelery. The emphesis will continue to be on more self regulation by jewellery manufacturing and retailers. Further liberalisation the gold import is live issue. Removal of all the remaining restriction on gold imports has been advocated by many of following groups:- Trade liberalisation for gold is a pre requisite for financial liberalisation. There is no specific advantage in restricting gold imports to the select no. Of nominated agencies. If gold is imported farely under full fiscal benefits will accure to more deregulation of gold in india. Going by Turkish example, free imports under OGL and free export are pre condition for establishing a foothold in the world jawelery market . REGULATION IN PHYSICAL AND FINANCIAL MARKETS IN GOLD IS ANOTHER MAJOR ISSUE:- Regulation in general means formulation of norms by the regulatory for : a. Risk assessment and control the regulated institution. B. Investors protections. 5. BRINGING THE GOLD HELD BY THE PRIVATE SECTOR IN TO THE ECONOMIC MAINSTREAM HAS RIGHTLY BEEN AN OBJECTIVE THROUGHOUT:- Mobilization of gold by the gout. In the past did not yield any major long term benefit. Any government led mobolization has inherent disadvantages. A better alternative would be allow holders of gold to raise capital from the banking system by way of pledge. It would be inconsistent with the spirit of liberalization to discriminate against those who saved in gold in past. A machenism can be evolved where by banks leading in deregulation of gold in india. 6. IT DEVELOPED OF E- MAONEY :- It is possible that a private sector units of account that is linked to gold may come in to existence in india, given the fact of huge private sector gold stocks. It would be advantages to look in to this possible. 7. GOLD HAVE ANY OFFICIAL MONETERY ROLE LEFT IN INDIA:- Golds role in currency issue was braught to a level of insignificance in india. There is good evidence to support the view that gold is held as an inflation hadged in india. BRIEF DISCRIPTION ABOUT ANALYSIS OF DEMAND AND SUPPLY OF GOLD IN INDIA Demand for gold is likely to contain information regarding inflation expectations. Since monitory policy is reflected in the growth of money stock and ultimately the rate of inflation, there is a case for including gold in the monetory calculus. It need to analyse the advantages in including gold held by the private sector in the broad measure for liquidity, even though gold is not anybodys liabilities. Also gold could be included in the index for the real effective exchange rate for rupees. They also indicate that :- Other thing be equal. Gold import demand has real effective exchange rate of the rupees. This is the analyse function where we analyse how to demand and supply of gold commodity can run in the market and whoch factors affect to ush the demand and supply of gold in equal range. This is the chart which are showing consumption n different year and we aware that the consumption of gold in india and where they affect. supply and demand table CONCLUSION In that demand and supply of gold in india we analyse and learn that official sellin will fill the boots ot trend following speculation in the gold market and the gold price will fall back towards its prior trading range. The global recession and strong dollar which curb gold , jewellery and bar demand have been facilitating the ability of the official sector to keep the gold price low. The forces for higher gold price will build. Though it may not happen over the short run in the long run the dollar will fall- and substantially in our view. A dollar decline will lower than the price of gold in countries outside, which will in turn stimulate price elastic demand. The fear of weakness may also shift official sector attitudes towards holding gold as a reserve asset relative to the currency. Many central bank feels uncomfortable with the now higher share of currency in their official reserves. The huge and ever increasing internal debt of india growing prospects of inflations. The central bank has started objective of reducing its high reserve holding of money, and it may be noteworthy that they have reported the first rise in central bank gold holding in many years. As long as currency has holding remained strong, central bank have felt no pressing need to address their high mony holding, but an eventual reserval in the money exchange rate may change the perception. The supply will also lift the gold price. Over the last 4 year , the supply despite low prices because there was a pipeline project from the 1994-96 period of higher gold price the pipline has now been almost depleted. In addition high grade to improve cash flow at low gold price. High grading increase output over the near term but ultimately reduces overall life of mine output and brings forward in time depletion dynamics. At last it shows that the price of the gold is increase or dicreases then it doesent affect on the demand and supply of commodity because it is the investment which provide always benefit to the customers, due to previous record which was explain in previous topic and cover that price cant affect on demand and supply of gold in india or any country.

Celebrities and their Tibet Essay -- Expository Tibet Essays

Celebrities and their Tibet Tibet has long been a mystical land, a place that not many have known about. However this has changed. The celebrities have come out in force in making Tibet the center of attention. Even now, most people don't know more about Tibet than its location, somewhere in Asia. So, while the popular support of the struggle of the Tibetans has become well known due to the involvement of celebrities spreading the word, has it really helped the cause or simply let people know what is going on there? Even more importantly, is the information that the celebrities are passing on always correct? Before any of these questions can be answered though, one must first know the origin of the conflicts between the two regions as well as the history of the Free Tibetan Movement. As said above, Tibet used to be a place that not many people knew about. This made it much easier for the Chinese government to come in and take control of the people and the land without much protest from the outside world. In fact even if other countries, like bordering India, had known, not much would have been done. This is because no nation had ever recognized Tibet as an independent country. Rather, it was the events that followed which caused the uproar. According to defected citizens of Tibet that traveled to India and then dispersed throughout the world, the Chinese started a form of spiritual cleansing. Monks and spiritual leaders that would not follow their ground rules were detained, captured or killed. The lama's of the Tibetan people were either taken as political prisoners or exiled. However, there are also those that said that some of this never happened. "'The first troops had appeared in the city in September, 1951.' The ... ...Collins. 1969. Connolly, Paul.

Our Grandmothers By Maya Angel Essay -- essays research papers

Imagery In The Poem “Our Grandmothers'; by Maya Angelou Image (Imagery) – Descriptive poetry flourished. One basic meaning for ‘image’ is provided by that context, but other, looser and more treacherous, meanings have accreted: any sensuous effect provoked by literary language; any striking language; metaphor; symbol; any figure. Maya Angelou’s poem, “Our Grandmother’s,'; vividly exemplifies a sense of imagery that is brought to life. The most effective way that, Maya Angelou presents imagery to the readers is through the setting. Firstly, at the beginning of the poem the narrator describes the current state of the main character and gives a brief description of the setting through imagery. “She lay, skin down on the moist dirt, / … the whispers of leaves…/ the longing of hounds…'; (“Our Grandmothers';, 1-4). These lines are very effective to the readers because the imagery behind these lines allows the readers to feel the cool breeze blowing, hear the leaves rustling and even sense the smell of fear; everything that one could think of to enhance the setting of a plantation. Reading this poem is an escape from modern day life. As readers, we observe everything that the narrator and the main character experience. To fulfill the imagination of the readers, Maya An gelou concentrates primarily as to how the readers are going to interpret certain events. S...

Freedom Writers Essay Essay

What life holds for us is determined by how much we are willing to sacrifice. In the movie Freedom Writers, Ms. G is the main character. Her way of viewing life gives hope to the people surrounding her. In this essay, I am going to compare her willingness to sacrifice with the sacrifice I was once asked to make. Ms. G dedicated herself to teaching a difficult group of students. California had integrated the school system, which resulted in a culture of conflict and violence. She spent a lot of her time and gave up a lot of her family life in order to help people that she barely knew. Her desires to make a change were clear and honest. For example, she took evening and weekend jobs in order to buy books and take her students on trips. She also made herself available to help students with personal issues. She had a strong desire to help her students understand that they were worthwhile, and that whatever challenges they faced, they could make their lives better. As a result of these efforts, her students learned to trust her and became united with each other. They began to feel hope for their future. Even though Ms. G. experienced success and satisfaction in helping others, she faced opposition. Her marriage was jeopardized. Her husband could not understand why she spent so much time and energy with her students, and he often felt second in her life. He did try to cope with this lifestyle, but it was too much for him to deal with and he finally left the relationship. I also embarked on a similar adventure. In June 2002, I was called to serve as a missionary for The Church of Jesus Christ of Latter-day Saints in Denver, Colorado. While on my mission, I taught the gospel to Spanish speaking people. Like Ms. G, I was dedicated to a good cause working with Hispanic people. I also immersed myself in helping those people to overcome personal and family challenges. I sacrificed two years of my life to serve people I had never met. I did it with all my heart. I knew that teaching people how to apply correct principles in their lives was the best way for them to achieve happiness. My goal was to help others to understand the true gospel of Jesus Christ. Teaching people the principles I knew to be true helped them to improve their lives and find joy as well. For example, I remember one person I taught; his name was Enrique. He was addicted to drugs and alcohol. When I found Enrique he told me that, from using drugs, he had lost his sense of taste and his body was no longer able to produce sweat. He also shared with me that his life had no purpose. He would go to work to get money to buy drugs, which created an endless cycle. I felt deep sorrow for him and wanted to do something to help him. I taught him about how to overcome his addictions to drugs and alcohol. Eventually, Enrique was able to overcome these addictions. I helped him to learn English and he began school at a University. Later, he told me how grateful he was for the new direction that his life was taking. Not only was my service similar to Ms. G’s, but my challenges were also. My family was upset about me going away for so long because while I was away, I would not be able to help them financially. They told me that if I went, I might as well forget about them. â€Å"It’s either a mission or us,† they said. I knew that I could not abandon my commitment to serve a mission. I pled with my family to understand my decision, but they reluctantly dismissed me. Once I was in the mission in Colorado, I tried to write to my family to let them know I was okay and that I was making a difference in the world by helping people to overcome many of the challenges that tear individuals and families apart. My family never answered my letters. I knew that what I was doing was right, but having my family reject me in those difficult years made me feel abandoned. Nonetheless, I was determined to continue working to help the people in Colorado. Certainly, my experience was a much shorter period of time than Ms. G’s and eventually my family embraced me again, while Ms. G’s husband never returned. Also, she taught the same group of people for four years, whereas I traveled around and met new people. Nevertheless, during the time I served my mission, I, like Ms. G, learned what it means to give everything for a good cause regardless of the adversity. As Ms. G and I both persevered in doing what we felt was right, we discovered great meaning in our lives and the work we were doing. In conclusion, our ability to fulfill our duty is not determined by our environment or surroundings. Ms. G and I have shown that if people’s hearts are in the right place, their rewards can be greater than what they lose. Our service, strength, and willingness can make a difference in the world regardless of who we are, or what we are standing for.
