Statistical Inference and Regression - Essay Example Those who impress statistics tend to improve on the quality of data, the experimental designs, as well as survey sampling. They also give tools for forecasting, as well as prediction using statistical models. On the overall, statistics is quite applicable in many academic fields and it cuts across, the natural science, the social sciences, businesses and government. Statistical methods are used in summarizing and describing of collected data. Descriptive statistics is particularly useful in research work especially when communicating the experimental results. Patterns in data can be modeled in such a way that it accounts for the uncertainty or randomness in the observation, which are then used in drawing of conclusion about the given population under study (Bethea, & Boullion, 2005). This is what is called the inferential statistics. Inferences are extremely crucial elements as far as scientific advancements are concerned. It helps in providing a means through which conclusions are d rawn for the data that are subject to random variations. The application of both descriptive statistics and inferential statistics comprise applied statistics. The theoretic statistics are concerned with the logical arguments that underlie justification of certain approaches to statistical inference. Mathematical statistics involves the manipulation of the probability distribution that is necessary for deriving outcomes that are closely related to methods of estimation and the inferences (Bethea, & Boullion, 2005). Probability cuts across various fields and encompasses many definitions. This paper discusses statistical inferences and cuts across other areas of statistics including regression, linear regression, nonlinear regression, least-squires method, and the maximum likelihood method. Statistical Inference The term statistical inference as used in statistics is taken to mean the process of drawing or making conclusions from data that are subject to random variations. The example of statistical inference is the sampling variation or the observational errors (Bethea, & Boullion, 2005). More often than not, the terms inferential statistics, statistical inference and statistical induction are used in describing systems of procedures that may be used in drawing of concussions’ from data sets that arise from systems that are affected by random variations including random experimentation and observational errors. The initial requirements of the system of processes for the inference and the induction are that the system produces reasonable answers whenever applied to defined situations. It should also be general enough so that it can be applied in all situations. Maximum likelihood method. Estimation problems involve estimating the value of the one or many population parameters from any random samples of the population (Bethea, & Boullion, 2005). Point and interval estimation are the two categories of estimation. Interval estimation is used in determining t he probability of the outcome that occurs in any given limits while point estimation takes Fisher’s estimation. The term likelihood is also, one key concept used in statistical inference, and it is always calculated for any fixed sample while providing information about the relative probability of any sample data that is as a function of the distribution parameters. The likelihood function is used to measure how likely a given data sample is as the function of

My Mission Statement & Goal Plan Essay Example for Free

My Mission Statement Goal Plan Essay I may not convince the world that I can be the next Nobel Peace Prize winner. I may not persuade people to make me the next Time Magazine’s Person of the Year. Nor do I have any illusions of garnering millions of votes to become the next president of this country. But if I am to be given an opportunity to describe myself, all that I can honestly say is that, I am who I am. Thus, in an attempt to try and take a glimpse in defining the person I always see in front of the mirror, I have come to a resolution that the best thing to do is to find and understand my purpose in life. By doing so, I ponder to ask the question, why do I exist? In other words, my mission in life is quite an irony or for some, it may seem stupid or foolish. Simply put it, my mission in life is to find my mission life. Although many people may think that this statement is hilarious, I will respectfully beg to differ. There are millions of people living aimlessly spending every second of their time in confusion and uncertainty. And for me, this is a frightening reality and to a certain extent, it is a sad one as well. And I admit that I am afraid to be one of them. It is the fear of not knowing where I am, where am I going and what I want to do which has led me to set my life in constantly pursuing the truth behind my existence or purpose in this world. I believe that by doing so, can help me see even just an inch of the incomprehensible reality each person carries with him or her. In light of this, I have aimed to unravel my mission in life through a process of first understanding my short-term goals of knowing who I am and where I stand through the institution that I want to affect and influence my life. Then, I plan to venture into my long-term goals that reflect my dreams and ambitions not just a professional and a son but more importantly, as a person. Thus, in order to know and find one’s purpose in life, a person must first know and find who he is, where he is and where he wants to be. It has been said by Benjamin E. Mays that the tragedy of life does not lie in not reaching a person’s goal, the tragedy lies in having no goals to reach. To me, he makes perfect sense. Somehow, a person who has no goals, dreams or ambitions has nothing to hope for or to look forward to. I thus find it highly imperative to transfer to the University of Southern California as my primary short-goal. I know firsthand that life in this world is often measured by the amount of success, wealth and fame a person possesses. I am familiar with the University of Southern California. I believe that if I am to be given the opportunity to study in such a distinguished institution, such an achievement tells me that I will never find myself wanting to be more successful, wealthier and famous than I already am. Transferring to the University of Southern California reflects a bigger picture of my goal of constant growth and development. In this moment in my life, I know that the best thing to do is to further my knowledge and skills. Entering this institution is the wisest way of preparing myself for what the world will be showing and throwing at me. And I have to confess that I am afraid to take this step. Amidst all that have been happening in my life, I sometimes think that I have made a shadowy acquaintance, and its name is fear. But I have learned not to stand down anymore in the face of adversity. There is always the fear of not being good enough or failing. But I believe that my greatest fear is merely fear itself. And for me to overcome this, I have to keep walking and moving despite being afraid. People will constantly judge and criticize me. I know this and I have learned to live with it. I honestly get affected because I am a sincere person. I dedicate and commit myself to something I really believe in wholeheartedly. My friends and family will attest to this fact. I can guarantee that I am a person of principle with an unwavering confidence and an incomparable determination. I am absolutely confident that I can bring the person that I am to the University of Southern California. By transferring to this university, I have realized that I also have to achieve the goal of convincing other people that I want it and that I deserve it. If this is a business proposal then let me assure everyone that I am good investment. I believe in who I am and what I can do. All that I am asking for is for you to believe in me. In essence, my short-term goals are all about realigning my path not just on a good one, but more importantly, on the right one. My short-term goals can briefly show who I am based on what I have already been through. My short-term goals are the remaining few years before I venture into the real world. Furthermore, my short-term goals portray my desire to take a step and revolutionize who I am right now in becoming someone I hope to be. During the vast reign of the Roman Empire, a great man by the name of Marcus Aurelius Antoninus once said, â€Å"A man’s worth is no greater than the worth of his ambitions. † I somehow feel that ambitions can thoroughly define a person but at the same time, it can also break the person. Somewhere in life’s journey, a person will have to face the â€Å"non-negotiable† realities in their lives. These are the things that tend to be so difficult and even impossible to change. I have thus made my long-term goals into something practical and achievable for me. I have envisioned myself in about less than ten years as someone who runs his own business while also helping my father run his. I find my long-term goals to be realistic and honest. I do not have grand dreams of eradicating poverty or creating some out-of-this-world idea that will save us from global warming. I want to keep my feet firmly on the ground. But this does not mean that my long-term goals are plain, simple and self-serving. As matter of fact, I expect them to be challenging, tricky and risky. Running and having my own business is no walk in the park. In this modern age, the competition is so tight and the stakes are roughly high that being good falls short by a mile. This does not even include the fact that I will also be greatly involved in my father’s business. But I want to take this risk. How can people discover new lands if they cannot lose sight of the shore? If I am to venture into this, I need to be cutting-edge and have an innovative mind. This is why the link between my short-term goals and my long-term goals is very significant. I want to take it step by step without any shortcuts. Each stage in my life is a learning process where I grow and develop myself for my future. Most people describe who they are but what they have. Still, others know who they are by how they are described by other people. I for one believe that what I have and how others perceive me are just parts of who I am as a whole. I believe that the person who best knows who I am is myself. People may see me in terms of things I have or from their own point-of-views. But I can never be half the person that they say I am if I do not know and accept what I think and see that I am. This is why my short-term and long-term goals are all starting points to initiate my true purpose in life. Through these goals, I may somehow find a semblance or clue of what I truly want out of my life. Through these goals, I can find who I am. As Lao Tzu has said, â€Å"Knowing others is wisdom, knowing the self is enlightenment. † Simply put it, through acting upon my goals, I intend to find something that will grab my attention and interest that will make me dedicate my life to it. Some will spend their entire lives looking and searching, while others may spend their lives staring at a distance unable to move and make a difference. In the greater scheme of things, I like to believe that it is not about reaching or achieving that which I have set for myself but rather, it is all about how I get there that really counts. How wonderful it is if I can do the things people say I cannot. This is largely founded on the inescapable reality that obstacles will appear every now and then. As for me, the greatest obstacle and weakness I will ever face are being idealistic and fear, respectively. As mentioned earlier, there is always the constant fear of not being good enough or failing. In addition, although being idealistic is not really a bad thing, it also comes with a heavy baggage. By being idealistic, I tend to ignore the reality presented. There is a fine line separating what is in theory and what is in practice. Somehow and some time, this reality will slap me in the face. There is the need to be practical which I fall short of a lot of times. I do believe that there are three types of people in this world: those who ask what happened, those who watch things happen and those who make things happen. I have stopped asking what happened being blind and deaf to the realities of life. I have stopped watching things happen from the sidelines being apathetic to the things happening right before my very eyes. I have thus decided to change and to make things happen. I try to stop making excuses. I do not need an excuse to live but rather, I need a reason to live. And dedicating my life in search for my purpose is something I believe is worthwhile. It is about time to go beyond myself and offer who I am not what I have. If there is one thing I have learned and will never forget from this class is that achieving my goals or aspirations in life is neither an overnight phenomenon nor a magical trick that can easily be pulled instantly out of the hat. Dedicating myself to something I hold dear is always a process. It is an on-going process of continuous learning, understanding and growth as a student, as a son and as a person. These goals may not happen today, tomorrow, next week or next year. The important thing is that it does not start next year, next month, next week or tomorrow but rather, it starts today.

The Extraction And Purification Of Paracetamol Essay

The Extraction And Purification Of Paracetamol Essay Analysing the Quantity and Purity of Paracetamol Present in Different Formulations of the Commercial Medicine Aim The aim of this investigation was to determine the percentage by mass of pure paracetamol in formulations of branded paracetamol in 500mg tablets. Two techniques were used so as to determine this: -Extraction and purification of tablets by filtration and recrystallisation. -Hydrolysis of the drug under reflux followed by titration against ammonium cerium sulphate. In addition to this, the purity of the paracetamol was investigated by determination of melting point of the respective brands of paracetamol. Findings Using the extraction and purification procedure it was found that Tesco had the greatest percentage by mass of the active ingredient, paracetamol, at 46.8%. Morrisons tablet percentage by mass was 44.6% while Superdrug had a percentage by mass of 37.8%. Using the reflux and titration procedure it was found that Superdrug had the greatest percentage by mass of the active ingredient, paracetamol at 20.0%. The Tesco percentage by mass was 19.6% while Morissons was 18.5%. The melting point procedure concluded that all three crude samples had similar purity of paracetamol with melting point at 156oC. The melting point of the Morrisons recrystallised paracetamol was 168oC, Superdrug had a melting point of 165oC while Tesco had a melting point of 164oC. This shows that Morrisons had the highest purity of pure paracetamol followed by Superdrug and then Tesco. Underlying ChemistryHistory and Uses Paracetamol (C8H9NO2) (or acetaminophen) is the most common over the counter painkiller in the world. It was discovered in 1852 by Charles Fredric Gerhardt who later went on to discover aspirin. The drug is so popular due to the few side effects it has on the body and does not irritate the stomach like other commonly used drugs such as aspirin. The structure is as shown: Paracetamol is used for relief of headaches, fever, menstrual pain, back pain, toothache and other general pain; however it is ineffective against muscle pain as it possesses no anti-inflammatory properties. Non-opioid analgesics work by inhibiting an enzyme known as cyclooxygenase (COX). COX is a catalyst for the conversion of a fatty acid contained in cell walls—arachidonic acid—to substances known as prostaglandins. (tuftsjournal.tufts.edu.) Prostaglandins have many functions including the induction of pain. By reducing the production of prostaglandins the pain is relieved. Paracetamol does not affect the cause of the pain but rather combats the biochemical pathway which results in the feeling of pain. Prostaglandins also affect the hypothalamus in the brain, the centre which is responsible for the maintenance of our bodies internal environment despite changes to the external environment, i.e. homeostasis. The prostaglandins cause the body to raise its temperature, and hence by taking paracetamol the body temperature is lowered. Paracetamol is therefore classed as antipyretic as it lowers the body temperature. Due to these properties the drug is commonly used to combat flu and cold symptoms. The range of pain combatted by paracetamol alongside the fact that it has very few side effects has resulted in it being the most commonly used painkiller. Paracetamol is also popular because of the rate at which pain subsides from its use due to the rapid uptake in the body. Absorption: Rapidly and almost completely absorbed from the G.I. tract. Peak plasma concentrations are reached in 10-60 minutes.(labmed.yale.edu) Methodology Two techniques were used in the determination of the mass of active ingredient present in the tablets. The first was the extraction and purification of paracetamol from tablets. The second was an acid catalysed hydrolysis under reflux followed by titrations against ammonium cerium sulphate. The use of the melting point allowed the purity of the paracetamol to be determined. The extraction and purification of paracetamol This procedure extracted paracetamol from the tablets by crystallisation. The paracetamol tablets were crushed and dissolved in propanone at a raised temperature; this decreased the time required for the paracetamol to dissolve. The binding agents and fillers in the tablet are insoluble in propanone however the paracetamol is soluble. This results in the paracetamol forming a solution in the propanone while the other components of the tablet are left as insoluble residue. The solution was filtered to remove the residue. The filtrate was left to evaporate forming crystals of paracetamol. These crystals were then dissolved in hot water and then filtered through cotton wool to remove any binding agents left. This filtrate was left in the fridge and shards of paracetamol formed. This relies on the fact that paracetamol has a high solubility in hot water but a low one in cold water. This allows shards of paracetamol to form. The soluble impurities are only present to the level of a few percent and so never reach their limit of solubility and thus stay in solution. (Ellis, 2002) The pure recrystallised paracetamol was then dried and its mass measured. The percentage by mass was then calculated. Reflux and titrations This procedure required the paracetamol to be boiled under reflux for one hour with sulphuric acid. This acid catalysed hydrolysis broke down the paracetamol (an amide) into an amine (4-aminophenol) and a carboxylic acid (ethanoic acid.) The raised temperature was used so as thermally accelerate the reaction. The reaction is shown below: (Overall reaction) This reaction mechanism may be found in the appendix. The use of reflux apparatus ensured that the reaction vessel never boiled dry. This is because any vapour formed from heating in the reaction vessel was turned back into a liquid by condensation. The benefit of using a heating mantle was that it ensured that a constant temperature, heating the round bottomed flask over a greater surface area. This procedure produced 4-aminophenol. This has a hydroxyl group on carbon 1 and an amine group on the carbon 1. Since the nitrogen is attached to only one carbon it is a primary amine. The 4-aminophenol can then be oxidised using ammonium cerium sulphate, involving the loss of hydrogen from the 4-aminophenol using ferroin as an indicator. This produced iminoquinone. Only after all the 4-aminophenol has been oxidised will the cerium (IV) reagent oxidise the ferroin indicator from Fe2+ to Fe3+ (ferriin). (Ellis, 2002) This resulted in the colour change from red to yellow, as the red ferroin is oxidised to ferriin which is blue. This is shown in the diagram below When mixed with the ammonium cerium sulphate this produced a yellow colour which indicated the end point of the titration. A titration was also carried out without the test material being present and the difference between the values with the test species present and absent accounted for the mass of paracetamol present. The difference in volumes of titre required for the colour change is directly proportional to the mass of paracetamol present in the tablet (0.007560g per 1cm3 equivalent titre.) Melting Point By measuring the melting points of the given formulations, the purity of the paracetamol was able to be determined. Melting point apparatus worked by heating the species in a capillary tube which itself was inserted into a heating block. By looking through a lens at the species, the moment at which the species melted could be seen and then at this moment the reading on the thermometer could be viewed. When a substance is heated, there is an increase in entropy as the species is thermally excited. If enough energy is put into the substance, it results in a change of state, in this case solid to liquid. The three brands of paracetamol melting points were measured for the tablet, the crude and the recrystallised samples. Pure paracetamol is a white crystalline solid which melts at 169-171oC. (Ellis 2002). The impurities in the samples lower the melting points. The sample which was closest to the given melting point represents the purest sample of paracetamol. Procedures The Extraction and Purification of Paracetamol Please note this experiment was carried out twice for each brand and an average taken. This was then duplicated so as to improve the reliability. (This is shown in results as the replicate.) Paracetamol was extracted from three brands of paracetamol; Morrisons, Superdrug and Tesco. These procedures represent the procedure used for each brand. Two tablets were weighed using a balance (accurate to 2 D.P.) then crushed using a mortar and pestle. The ground tablets were placed in a beaker. 50cm3 of propanone was measured using a pipette. The propanone was used to rinse the mortar and pestle before adding it to the beaker. The beaker was left on a brisk stir at a low heat until the tablet was dissolved as far as possible. The insoluble material was the binding agents and fillers. Initially 20cm3 of propanone was used however it was found that the tablets did not dissolve fully. A Buchner Funnel was set up as shown (see left.) The insoluble material (binding agents and fillers) collects in the filter paper. The filtrate (propanone and paracetamol) is collected in the filtering flask. A little propanone was run through the filter paper so as to create a seal between the filter paper and the base as shown on the above diagram. This prevented the insoluble material from passing through the holes in the funnel. The content of the beaker was passed through the funnel and a little propanone was used to rinse the beaker. The filtrate was left in an evaporating basin overnight in an oven. This formed crude paracetamol crystals. The mass of the crystals was taken. The crystals were placed in a beaker and 20cm3 of hot water was added. The beaker was heated on a brisk stir until the paracetamol had dissolved. This was passed through a warmed wet piece of cotton wool in a warmed glass funnel. This was to prevent the paracetamol from recrystallising in the cotton during filtration. The filtrate was passed directly into a basin. The basin was placed in the fridge overnight to cool and to allow the crystals to form. These crystals were white. The recrystallised paracetamol in water was passed through a piece of fluted filter paper to collect the crystals. (Initially the paracetamol was filtered out of the water using a sintered glass crucible however this produced a lower yield as crystals were lost when using this technique. See table 22.) The filter paper and crystals were placed in an oven at room temperature overnight to allow the crystals to dry. These crystals were white. The dry mass of the crystals was measured. This procedure was replicated for each brand of paracetamol. Reflux and titrations Please note that this procedure was carried out once for each brand of paracetamol. This was then duplicated so as to improve the reliability. (This is shown in the results as the replicate.) The first stage of this procedure involved the acid hydrolysis of paracetamol: 15cm3 of 2 molar solution of sulphuric acid and 25cm3 of water were measured using a pipette and placed in a 100ml round bottomed flask. To this 0.30g of crushed (using mortar and pestle) paracetamol tablet was added, having measured the paracetamol using a balance (accurate to 2 D.P.) This was swirled and warmed until the tablet was dissolved. This was then boiled under reflux for one hour in a heating mantle as shown below: The paracetamol and sulphuric acid were placed nn the round bottomed flask. The solution turned from colourless to a light golden colour. The solution was cooled and 100cm3 of water was added. 20cm3 of the resulting solution was pipetted into a conical flask with 15cm3 of 2 molar Hydrochloric acid, 40cm3 of water and precisely 8 drops of ferroin indicator. This was then titrated against 0.1 molar solution of ammonium cerium sulphate until colour changed from a pink/peach colour to a cloudy yellow colour. (The colour change was not very obvious during this procedure. Therefore previous titration colours were kept beside the species to try to standardize the colour at which the end point of the titration was determined.) The titrations were repeated until two results were within 0.1cm3 of each other i.e. until two concordant results were obtained. The apparatus is as shown overleaf: The burette was filled with the yellow ammonium cerium sulphate solution and the conical flask contained the paracetamol acid mixture. This procedure was also repeated without the test material present. Melting Point During this procedure, the melting points of the recrystallised, crude and unaltered tablet forms of paracetamol were investigated. The sample of species was crushed into a powder using a mortar and pestle. Capillary tubes (1mm diameter, 10cm long) were sealed at one end using a Bunsen burner. This provided a place to hold the paracetamol when using the melting point apparatus. The capillary tube was placed turned open-side-down and pressed onto the paracetamol formulations. Then the closed end of the capillary tubes was gently tapped on the table to allow the paracetamol to fall to the closed end. This was then placed open-side-up into the metal heating block alongside a thermometer. The temperature was slowly increased using the thermostat on the melting point apparatus while the paracetamol was viewed through the magnifying glass on the apparatus. The point at which the paracetamol melted was then recorded. Results Initial Extraction and purification The crystals of the crude and recrystallised paracetamol were both white. The crude crystals were prismatic shaped while the recrystallised paracetamol formed long shards.

Two techniques were employed so as to determine this: -Extraction and purification of tablets by filtration and recrystallisation. -Hydrolysis of the drug under reflux followed by titration against ammonium cerium sulphate. In addition to this, the purity of the paracetamol was investigated by determination of melting point of the respective brands of paracetamol. The results of these procedures are discussed below. Extraction and purification Using this procedure it was found that Tesco had the greatest percentage by mass of the active ingredient, paracetamol, at 46.8%. Morrisons tablet percentage by mass was 44.6% while Superdrug had a percentage by mass of 37.8%. Reflux and Titrations Using this procedure it was found that Superdrug had the greatest percentage by mass of the active ingredient, paracetamol at 20.0%. The Tesco percentage by mass was 19.6% while Morissons was 18.5%. Results were different for each respective brand of paracetamol and different between the two procedures. Melting Point The melting points of the crude paracetamol were all 156oC thus showing that all formulations of crude paracetamol had similar purity, and hence the first crystallization of the paracetamol was carried out very accurately. The melting point of the Morrisons recrystallised paracetamol was 168oC which compared well with the given melting point of 169-171oC. Superdrug had a melting point of 165oC while Tesco had a melting point of 164oc. This shows that Morrisons had the highest purity of pure paracetamol followed by Superdrug and then Tesco. Evaluation Evaluation of procedures Control of variables During the filtration and recrystallising process two tablets were used in each sample and two samples were taken. This, alongside the duplication of results, gives 8 tablets which were used in the determination using this method and an average taken. This increased the reliability of the results. During the procedures the same balances, burettes, flasks and pipettes were used so as to reduce the effects of error in these measurements. When titrations were carried out, a rough titration was initially done so as to determine the equivalence point. This was followed by accurate titrations. When two concurrent values were within 0.1cm3, an average was taken between these two values. The average was used to determine the mass of pure paracetamol greatly increasing the reliability of the results. Since the end point of the titration was not very obvious, previous titrations were kept aside so as to standardise the intensity of yellow in the solution, so that all titrations had the same end point colour. This increased the reliability of the titrations. All equipment used was cleaned using propanone to prevent chemicals from previous experiments contaminating this investigation. In addition to this the burettes and pipettes were rinsed with the solutions, before being filled with the same solution to prevent contamination. When using the balance, as far as possible, it was placed away from draughts and windows so as to prevent the wind causing error in the weighing of substances. Where possible, all reaction vessels and weighing receptacles were rinsed using a little of the liquid which would be used. This increased the yield of results, preventing the reactants being lost in the process. Modifications Initially, when dissolving the paracetamol in propanone, the tablet was not crushed however it took an inordinate time for the tablet to dissolve; by the time it had dissolved most of the propanone had evaporated The volume of propanone was increased from 20cm3 to 50cm3 because more paracetamol dissolved. This allowed a greater percentage of the paracetamol to be extracted from the tablets. Consequentially it took longer for the crude paracetamol crystals to form. Initially a sintered glass crucible was used to filter the recrystallised paracetamol. This resulted in the paracetamol being lost, so filter paper was fluted and used instead. This resulted in a greater mass of recrystallised paracetamol being collected. When the paracetamol was being added to sulphuric acid, initially it was unheated and just swirled, however not all the paracetamol dissolved and hence, the sulphuric acid was warmed with the paracetamol to dissolve the crushed tablet before being boiled under reflux. When using the ammonium cerium (IV) sulphate, it was found that if left for any length of time greater than one hour the solute came out of solution, therefore, before pouring the solution into the burette, it was stirred vigorously using a magnetic stirrer to ensure the same concentration of solution was used in every titration. Because of this, the burette was only set up immediately before use. Evaluation of results Both procedures resulted in significantly lower percentages than the mass of paracetamol in each tablet as stated on the box. The expected percentage by mass was expected to be 90.9%. This is calculated as shown: Mass of tablet – 0.55g Mass of paracetamol (on box) 0.50g (0.5/0.55) x 100 = 90.9% Generally the replicate compared well with the initial experiment, with a maximum difference of 4.6% by mass for the first procedure. For the second procedure there was a maximum difference of 5.2% by mass. This can be put down to errors in the equipment and human errors when carrying out procedures. The fact that both procedures indicated different formulations contained the most paracetamol, may be due to the fact that often paracetamol was taken from different blister packs, and hence from different batches, which may contain different masses of paracetamol. However human errors and errors in equipment are more likely to be to blame. It can also be broadly sai

Topshop Marketing Plan

Market OverviewTarget market: The Topshop Corporation focus on the customers of young people, who is between 15 and 30 years old, especially for young females who likes to pubbing, clubbing and have a sense of fun. For this moment, our consumer market niche is not the higher income level but the young people on budget. Customer profile:Our customer profile is young people driven by a need to be fashionable and trendy, they like all trend setting magazines. Our brand also appears to students, professionals, fashion taste makers and high profile A-List stars alike. Competitor profile:The main competitors includes H&M, Zara, French Connection and GAP. These companies are all retailer corporations, which has international business and online retail stores, and larger market shares in fashion retail market comparing with Topshop.Marketing ObjectivesGoals . The objectives can be divided into two parts. Firstly, the Topshop Corporation is focusing on the international business, the recent o bjective is built more than 100 stores all over the world in less than five years to raise the awareness of the brand. Secondly, in order to increase the sales, the Topshop corporation decides to expand their market targeting level, raising the brand position, promoting the cooperation with famous international fashion designer, the objective is to build a international fashion brand with different position of sales.Marketing StrategyYour strategy and marketing mix: [Use this section to summarize the overall strategy and marketing mix (The 8 P’s Product: The Topshop corporation will not change fashion clothing as its main product, but more accessories will be promoted to the market,Place and Timeï ¼Å¡ Price Promotion Process Physical Environment PeopleProductivity and Quality you will use to position yourself within the market to meet your customers’ needs. Whatever your strategy, you goal should be to differentiate yourself from your competitors to encourage customer s to choose your business first.]Action Steps Top 10 Action Steps: [Create a list of the Top 10 action steps that will bring your theoretical objectives (your marketing strategy and objectives) to life. E.g. Finish S.W.O.T. Activity Sheet, complete marketing budget] Background AnalysisThe background analysis should give a snapshot of where you are right now, where you have been and where you want to go. Undertaking this process will help you to define your business's capabilities and find opportunities within your particular market. Finally, defining your core business elements will ensure that your marketing plan and overall business strategy work together seamlessly.Business overview [The overview should cover the nuts and bolts of your business including:The name, structure and date of establishment Topshop is a British multinational retailer which specializes in fashion clothing, shoes, make-up and accessories. It was established in Sheffield, UK, in 1964. Details about the owne rs (their names, roles and levels of experience etc.) What your business is about (your business mission, vision and values) The key business objectives you would like to achieveAn outline of the main products and services sold A financial analysis of your business including sales and profitability A S.W.O.T. analysis of your business to set a line in the sand]SWOT analysisThe strength of the Topshop Corporation is that the owner of Topshop is the  Arcadia Group, which can provide favorable management and strong financial support for its subsidiary company. Moreover, the Topshop brand has take a large market share in the British mainland, the influence of the brand is deep among British people, and it has more than 300 stores nationwide and provides many different kinds of choices in product lines and design variety of products with thousands of looks per season creatively.The weakness of the Topman Corporation is their international market, the company is global, but it has store s only in a few countries worldwide, the market share is poor in US and China which are the two biggest markets in the world. A large number of staff and products make it difficult to manage and increase the management costs. And, big store space lead to weak customer services. On web shopping, there is no detail and size for accessorizes.The opportunity for the Topshop Corporation is the potential market in the oversea market. There are lots of young people in China and US, and they have great purchasing power, which is a good opportunity for Topshop to invest. And compared with other fashion retailers, it is not just targeting at young people, but also white-collared workers and a part of mid-aged persons who follow the latest fashion.The threats are from the competitors like Zara, H&M and French Collection. Like Topshop, they are all fashion clothing retailers, the competitors may have lower market shares in Britain than Topshop, but their sales are mostly from the overseas marke t, and their brands have been accepted by the local people. If Topshop want to expand the oversea market, it is necessary to show its unique features and improve quality and retain low price and good design, and face some limitations from government policies and to know about the cultural and demands of the local environment as soon as possibleObjectives: Vision and mission:The Topshop Corporation is an international fashion retailer, it has over 440 shops all over the world, more than 300 in Britain, which takes more than  50%. For the recent years, the British economy was not very good, so the sell in the mainland was below average. In the age of rapid globalization, technological innovation, population boom, and environmental change, the need of international marketing are pressing. From the topshop international segmentations, we can get the point that the international market has not been fully developed.US, the biggest economic entity in the world, only have four topshop sto res, and the second biggest economic entity, China, only have one. This market shares is not enough in these two countries. Take Zara as an example, we can know the importance to expand an oversea market. The Zara Corporation is a Spanish clothing and accessories retailer, very similarly with Topshop, but Zara opened more than 150 stores in China, almost every big cities in china, and Zara corporation’s sales grew with an amazing speed, and became the leader in the fashion clothing industry.The first goal is named â€Å"explore the new world†, which means the Topshop Corporation is aimed at developing the oversea marketing, especially China and US. The plan for the company is to open 50 stores in China and 40 stores in US in the next five years.The second goal is named â€Å"the social network†, the point is aimed at e-commence. In China, E-commerce is becoming more and more popular nowadays, in the date of 11 NOV and 12 DEC every year, there will be a large dis count online, on those date the sales will be more than 35 billion RMBs, the number is really amazing. The topshop has already had their online stores, and also have international business online, but only takes small shares. Our plan for the company is to build a world level website in different countries, and develop overseas online market.StrategyThere are some steps to finish the strategy, firstly, the advisement.For the customers in China and US, they may not very familiar with the new brand, so a good promotion is very important for Topshop. In the advertisement, we should emphasis our brand is designed for local people, for example, in China, we should highlight that the fashion clothing are designed for the eastern people, and integrated with some local culture cooperate with some famous designers to promote the new product.To open the Chinese market, the first thing our brand needs is to publish Production Promotion Release Conference in the biggest cities in China like Bei jing or Shanghai, and open the first store in the central zone of these cities. In the summer of 2013, US famous fashion retailer brand Hollister open the first store in Salitun, Beijing, which is the popular commercial district in China, and release a fantastic fashion model performance, after that the sales of the store was growing very fast. This movement raised the awareness of the brand and gained more popularity among young people, the topshop may learn a lesson from it.

US Achievements In WW! essays

US Achievements In WW! essays President Woodrow Wilson announces his Declaration of War in April of 1917. The United States wanted nothing to do with this war, yet were somehow dragged in. It all started in March of 1917 when Kaiser Wilhelm of Germany decided that unrestricted submarine warfare was the only way to stop war goods from getting overseas. Then, the Zimmerman Telegram came into the picture. This telegram was sent to Mexico from Germany asking them to attack America. With this, Wilson decided that it was a good idea to enter World War I with his declaration of war in 1917. Without the arrival of the Americans, it is likely that the Germans would have won the war. After the war was won, however, Wilson made his 14 Points. These 14 Points focused on repairing the World and achieving American objectives. The Germans seriously underestimated the potential impact of American involvement. They engaged in unrestricted submarine warfare and killed innocent Americans. This happened because of the sinking of the Lusitania in 1915. This was a passenger ship moving between America and England, which had passengers from both countries. 128 Americans died on that ship, and Wilson thought that Germany should pay. After the Lusitania was sunk, America found out about the Zimmerman Telegram. In March of 1917, Germany sent Mexico a telegraph asking if they would attack America. President Wilson thought that something should be done since they were being dragged into war. This is when Wilson announces his declaration of war in April of 1917. Wilson asked congress to declare war on Germany, which was approved on April 6th. Wilson wanted to make the world safe for democracy. The Armistice began on the 11th hour of the 11th day of the 11th month in 1918. 116,000 United States soldiers dead along with a total of 9.3 million killed in the war. Peace talks were made at the Versailles Conference and Wilson, on his way to Paris, ...

How to Quote a Poem in APA Referencing

How to Quote a Poem in APA Referencing How to Quote a Poem in APA Referencing Many style guides have special rules for quoting poetry in an essay. In this post, for example, we will look at how to quote a poem using APA referencing. This will cover both: How to present quoted verse on the page How to format in-text citations for a poem in APA referencing If you are writing about poetry, then, make sure to follow the rules below. How to Quote a Poem The basic rules for quoting a line of poetry are the same as for quoting any other source. As such, to quote a poem, you should: Place the quoted text within quotation marks. Cite the author’s surname and year of publication in brackets. If available, include a page number for the quoted passage. Otherwise, a single line of poetry will look like any other quote. If you’re quoting two lines from a poem, though, you will need to include a include a forward slash to show where the line break was in the original text. A two-line quotation would therefore look like this: One of the most famous examples of nonsense poetry is  Ã¢â‚¬Å"The Owl and the Pussy-Cat,† which begins thus: â€Å"The Owl and the Pussy-cat went to sea / In a beautiful pea-green boat† (Lear, 1983, p. 34). Here, for instance, we’re quoting the first two lines of an Edward Lear poem. Importantly, the date cited here is for the book the poem appears in, not the poem’s original date of publication (1871). The page numbers in the citation, meanwhile, show us where this poem appears in the book. Name a more iconic duo. Quoting Three or More Lines of Poetry If you’re using more than two lines from a poem, APA rules require you to format it like a block quote. Ideally, you will also recreate the presentation of the lines on the page from the original source: The final stanza begins with an interspecies wedding: â€Å"Dear Pig, are you willing to sell for one shilling   Ã‚   Your ring?† Said the Piggy, â€Å"I will.† So they took it away, and were married next day   Ã‚   By the Turkey who lives on the hill. (Lear, 1983, p. 34) Here, for example, we indent the second and final lines more than the rest of the quote. This is because the original poem is presented in the same way. Furthermore, as with any APA block quote, the citation here comes after the final punctuation in the quote, not before it. Adding a Poem to an APA Reference List Finally, if you quote a poem anywhere in your work, it should also appear in the reference list at the end of your document. The correct reference format to use, however, will depend on how the poem was published: For long poems published as standalone works, use the standard book format. You can do this for anthologies with a single author, too, but make sure to name the editor as well as the author of the poems themselves. List poems published in an anthology as chapters from an edited book (i.e., include details for both poem and container volume). List a single poem found online as a web page. Whatever their format, make sure to provide full publication information for all poems and their container volumes (i.e., the book or website where you found the poem). This will allow your reader to find them if required. And if you need anyone to check your document for errors – including in citations and the reference list – don’t forget that we have expert academic proofreaders on hand and ready to help 24/7.

New Year Eve in Different Countries Essays New Year Eve in Different Countries Essay New Year Eve in Different Countries Essay Julia Deegan Ngan Do Eva Fraga November 15, 2012 Compare and Contrast New Year Eve in Different Countries Wouldnt it be fun to travel around the world and celebrate the New Year all year long? All over the world, people celebrate the New Year; This is one of the oldest of all holidays. Most New Year celebrations focus on family and friends, food and traditions, but not all of the celebrations take place on the same day or in the same way! Because people in different parts of the world use different alendars, accordingly, Mexico and Ukraine celebrate the New Year on the first day of January, whereas Vietnam keeps a lunar calendar. In Mexico and Ukraine official date of New Year celebrations is from December thirty-first to January first. Vietnamese New Year takes place from the first day of the first month of the Lunar calendar, and its around late January or early February, until at least the third day.

Analysis of Corporate Governance by Monks, Robert & Minow, Nell Article

Analysis of Corporate Governance by Monks, Robert & Minow, Nell - Article Example As a result, the managers strengthened the company’s governance by ensuring that their imperative efforts focused on their judicial systems reforms, property rights, and informational freedom as well as evaluating other institutions that were vital for realizing democratic market economies. In addition, Banca Comerciala Romana of Romania experienced successful cases of good corporate governance in 2004. Due to itemized corporate governance, the institution was able to access cheaper debt that made it possible for the bank and its affiliate rating agencies to access lower borrowing costs. Fitch Ratings upgraded both individual ratings and long-term counterparty ratings from C/D and BB- to D and B+ respectively. The company cited the upgrading of the ratings came because of the improvement of corporate governance. They were able to manage the bank’s risks that led to changes that brought the bank back to European Union standards hence acting as a role model for the other financial institutions in the region. Furthermore, good corporate governance brings success in companies since it helps facilitate profit-making operations. With good corporate governance, investors will not just assume whether the company will perform better, but knows it will perform best due to better corporate governance (Monks & Minow, 63).  Ã‚   According to the study, the companies transformed due to affirmed systems of good corporate governance. The refining and developing of standards of corporate governance often followed cases of failures within the subjugated company. For instance, in the late 1990s, there were bursts of high technology bubbles associated with telecommunication companies. As a result, there was the development of interests by both brokers and analysts that led to conflicts, underpinning the ability to introduce the principle that would bring advice and analysis into the new system of corporate governance. Enron is one of the companies that felt the heat of failed corporate governance as it pointed the source of its failures to the auditing committee. The auditor and audit committee was an independent body thus mistakes involved during corporate governance application led to deficiencies due to failed accounting standards. Enron’s system of corporate governance failed due to lack of advice and an alysis principles. Another failed case of corporate governance is that of Parmalat. The Parmalat is a group of companies in Italy that deals with dairy food business worldwide. In December 2003, the company’s management team announced the collapse of the company due to lack of funds and entered into the bankruptcy protection program.  Ã‚

Domestic and Nominated Subcontractor Essay Example | Topics and Well Written Essays - 2000 words

Domestic and Nominated Subcontractor - Essay Example Domestic Subcontractor Domestic subcontractor is one whose selection and appointment is completely taken care by the main contractor. The employer plays no part in the selection or the appointment process except for giving consent to the selection and appointment if it is required under the contractual agreement between the employer and main contractor1. Roles and Responsibilities of Employer The roles and responsibilities of an employer with respect to a domestic subcontractor are very limited. The complete responsibility of a domestic subcontractor lies on the main contractor. The employer will play no role in the selection and appointment of a domestic subcontractor, until and unless it is required by the terms and conditions in the agreement. The employer shall be responsible for the subcontractor only if it is stated with a particular condition in the contract. Nominated Subcontractor As per the FIDIC 1999 red book, the definition of a nominated subcontractor is as follows: â₠¬Å"Nominated Subcontractor† means a subcontractor: a) Who is stated in the contract as being a nominated subcontractor, b) Whom the engineer, under the clause 13 [Variations and adjustments] instructs the contractor to employ as a subcontractor2. Nominated subcontractor is one where the employer approves, selects or nominates a contractor to carry out a specific task or a subcontract. In order to understand the roles and responsibilities of the employer with respect to a nominated subcontractor, it is first necessary to understand the reasons behind using such a system. There are numerous benefits associated with nominating a subcontractor for an employer. One of the main benefits is that the process of nominated subcontractor gives the employer certain control over the selection of suppliers or subcontractors. This control over the choice and the required performance from the subcontractor ensures certain level of quality for the employer. This privilege is without having to be directly involved with the subcontractor. The choice of subcontractor is entirely rested with the employer even though the main contractor needs to approve the subcontractor. Another benefit is that the employer need not get into any contractual agreement with the subcontractor. This is because the nominated subcontractor will enter into a contract with main contractor and not the employee directly. Hence, the employer will not have any contractual arrangements with the nominated subcontracts. Also there are other reasons that might be responsible for the nomination of a subcontractor such as the proven track record of nominated subcontractor, low pricing or high quality or even certain combination of the two, long term relationship between the employer and subcontractor, etc. The employer can also have a say in the terms and conditions of the subcontractor such as pricing and scope of work. One of the specific situations, where nominated subcontractors are used is when there is a need for a subcontractor to start working prior to the appointment of a main contractor. Such a situation would arise when a specialist task takes more time to complete than the actual construction programme. Hence, in such situations it becomes very beneficial to use a nominated subcontractor. Roles and Responsibilities of Employer Following are the roles and res

Standard and Non-Standard English Essay Example | Topics and Well Written Essays - 1000 words

Standard and Non-Standard English - Essay Example Whether we like it or not, there exist some of variations of the English language. In America alone, a great deal of language variation can exist within the bilingual or English as a Second Language (ESL) classroom, in both English and in the non-English languages. In a bilingual setting in Los Angeles, one teacher identified three varieties of English and three varieties of Spanish in her classroom. Each variety carried with it information about social status and the cultural background of the speaker: Instruction officially went on in the standard forms of English and Spanish, but students used two other varieties of English-Black English and Chicano English-and two other versions of Spanish-Chicano Spanish and a rural northern Mexican variety (Ovando et al., 2002). Globally, Kachru (1992) had also revealed the varieties of English spoken worldwide on the basis of countries in which English is spoken. Kachru (1992) divided countries based into three types labelled the Inner, Outer and Expanding circles. Examples of the inner circle of essentially English-speaking countries include the USA, UK, Canada, New Zealand and Australia. Traditionally non-native speakers have looked to these varieties as providing standards and norms to which they are expected to conform. McArthur (1994) argues that there is now a fair degree of standardisation between many English-speaking nations. Not only the UK and the USA are fairly standardised in their English usage, but Australia, Canada, New Zealand and South Africa as well, fall into this group. Despite some level of standardisation, important differences remain. There are still many people from many regions who manifest significant divergence from the norms of "mainstream" English usage. Trompenaars (1993) summed up the essence of the problem: " as we all know, even the English and Americans are separated by a common language which is used quite differently in different contexts and which has some serious differences in the meanings of individual words" (p. 69). However, although there are regional differences within the native inner circle varieties, people who speak these regional variants have control of and understand the standard native variety of the country in which they reside. Problems in communication need not arise and therefore difficulties in communication between native speakers speaking different varieties of English will not be covered here. Moreover, the Outer Circle refers to countries where English functions as one of many languages and has an official (e.g. Nigeria), or an "associate official language" (India) status. English is used in these countries for a variety of purposes including educational, social, administrative and literary domains. Examples include Singapore, Malaysia and the Philippines. Countries in the Expanding Circle use English as an international language. The speakers do not have a colonial past and the English they learn is based on Inner Circle varieties. Speakers have differing degrees of competence, there are little in the form of shared norms, differences occur mainly in proficiency. In these countries (Japan, Korea, Taiwan, etc.) the number of users is increasing rapidly. The problem with standard and non-standard varieties of English in education is that grammar is usually sacrificed. This is because children learn the structure of the English language-its grammar- intuitively as they learn to talk;

Main Messages Conveyed to the Indians by Clarks Address Essay - 2

Main Messages Conveyed to the Indians by Clarks Address - Essay Example It is evidently clear from the discussion that the language Clark uses in addressing the Indians is significant. He refers to them as â€Å"children†. This was done to establish a position of authority over them. He indicates that the Great Chief would take care of them, just like a father would care for his child, but only if they are obedient to the Great Chief. In modern times, this type of speech would be considered very demeaning if directed from one culture to another. In defense of Clark, he probably was mimicking the type of speech he thought the Indians would understand and react to in a positive manner. The researcher states that some of the Indians probably did react in a positive way to Clark’s message. The lure of more luxury items and better housing would have been a great incentive for some Indians. But other Indians would have been resistant to the message. Not all Indian cultures were the same. Some place a greater value on acts of bravery and warfare t han on having luxury items. They would have probably rejected the offer to visit with the Great Chief. President Jackson justifies the removal of the Cherokee Nation to the lands west of the Mississippi River in several ways. He argues that this removal will be good for the United States and the Cherokee Nation. It will be good for the Cherokee Nation because it will allow them to be free of the control of the states. They will be removed to lands that they can inhabit and call their own. They will be able to run their own governments, practice their own traditional religion and preserve their culture from destruction by the white man. He also argues that the Indians will benefit because the government is going to pay for the entire cost of their resettlement. He goes on to state that through philanthropy, the United States had attempted to help their tribes, but they would not respond to the help.

Current censorship of internet in China Essay Example | Topics and Well Written Essays - 3750 words

Current censorship of internet in China - Essay Example This essay analyses the process of media filtering in China that is by far the only country that is practicing the process very extensively. Unlike many countries, the internet censorship in China is carried out at multiple levels to ensure that no unfavorable information reaches the users through internet. The major reason behind China’s severe censorship is that unlike other countries that have been aiming at a single objectionable area to be blocked, China has listed a number of issues ranging from political to moral as objectionable and required to be censored. Internet censorship in China has its roots inveterate in times before the invention of internet. Every form of media has been censored through it various stages. Although internet censorship has its existence in almost all the states within which internet is accessible to a common man, the role of censorship in authoritarian states like China and Saudi Arabia has an increasing importance. It is because of the fact t hat the internet provides the nongovernmental organizations and citizens to reach out to the global communities, arrange global activities, express their ideas and obtain the non-conservative ideas of the non-Chinese. Since such activities pose a direct threat to the government of China, there is a continuous monitoring of internet usage and filtering of certain material from the internet to maintain the eroding governmental control. The content that is available online is censored on the basis of the ideas and thoughts expressed in them.

Japanese product Essay Example for Free

Japanese product Essay Historically, it would one impossible to conduct a discussion on the issue of American interest in the culture and society of Japan without mentioning World War Two. The conflict between the two nations during the 1940s forever linked each other as the landscape of the culture of modern Japan and the modern United States were shaped from the outcome of World War Two. In that regard, the histories of the two nations are forever interlocked. While one would assume that such an interlocking fusion would yield a negative, the reality is that the two countries eventually opened each others minds in terms of accepting each other. Granted, there are still obstacles present to understanding each other, but the acceptance and understanding between the two culture have been advanced do to eventual infusion of Japanese pop culture entertainment into the American conscious. Unfortunately, not all presentations of Japanese culture are presented with a clear understanding of the basics of Japanese societal structure. Any attempt to understand the Japanese must begin with their version of what it means to take ones proper station. Their reliance upon order and hierarchy and our faith in freedom and equality are poles apart and it is hard for us to give hierarchy its just due as a possible social mechanism. Japans confidence in hierarchy is basic in her whole notion of mans relation to his fellow man and of mans relation to the State and it is only by describing some of their national institutions like the family, the State, religious and economic life that it is possible for us to understand their view of life. (Benedict) A significant reason that Japanese culture has been embraced by those in the west centers on the fact that many people are exposed to Japanese pop culture when they are very young. The operative point here is that what people are exposed to are the more pop driven forms of Japanese entertainment. It is not the classics of Japanese cinema that helps to define a consciousness in the eyes of the public. Most people are not familiar with classic films such as YOJIMBO or GATE OF HELL of KWAIDAN. What people become familiar with are the various anime films, manga periodicals, etc. This is not because the public looks for lowbrow entertainment as much anime and manga output from Japan is very sophisticated in the storytelling techniques that are explored. Much of the reason that these forms of Japanese entertainment are so popular is that they utilize genres that â€Å"travel† well. In other words, regardless of which culture produces a horror comic, an action-adventure film, a sci-fi fantasy, very little is changed in terms of the way those types of genres are constructed. A comedy, however, centers far too much on a specific culture understanding of a particular humor to be effective. Since much of the output from Japan that reaches the United States borrows from genres that â€Å"travel† well, the ability for the American public to accept the Japanese product is maximized. (Actually, it is further maximized in light of the quality level of the writing that helps hook audiences) This does not mean, however, that there is a cohesion of understanding of the Japanese culture by the American audiences mainly because much of the homegrown American entertainment that uses Japan as a backdrop generally offers a very stereotyped image of Japanese society designed to be ‘swallowed’ by an American audience that has very limited knowledge of the actual culture. This can be viewed in such films as LOST IN TRANSLATION and the landmark film (in terms of providing a skewed insight into Japanese culture) BLACK RAIN. This is not to say that the purpose of BLACK RAIN was to present an inaccurate depiction of Japanese people. What the purpose of BLACK RAIN was, on a deeper level, was to provide a complicated scenario for the Michael Douglas character to overcome the obstacles in his way in order to achieve his goal of capturing the villain. The obstacles in BLACK RAIN, however, are fairly insurmountable: he is a stranger in a strange land who has difficulty functioning on his own and is forced to put his stubbornness and his prejudices aside so that he can bond with a Japanese police officer in order to achieve his objective. The character that Michael Douglas plays, however, is a complicated corrupt loner who is his own worst enemy. He is distrustful and keeps people at arms length. By being forced to accept help from these people who he has nothing in common with, he is able to ultimately grow as a person. Like the character Michael Douglas plays, Japanese culture is ripe with complexity. The culture is different and the way people interact with each other in Japan is far different that the way people interact with each other in the United States. While BLACK RAIN does shows these differences, it does not go beyond the surface value of the differences to provide a more complex side of the Japanese. As such, the Japanese characters often appear one dimensional and border on stereotypes.

Internet Responsible For Social Changes In Teenagers Media Essay

Internet Responsible For Social Changes In Teenagers Media Essay In 1950s, the first electronic computer was invented. This made work of day to day life very easy for the working population. But later in 1980s, the first world-wide Internet Protocol Suite was regulated and the world-wide network of all the computers interconnected through IP/TCP was called INTERNET. Then it started bringing reforms in working style, schools and education and recreational activities. Later, social networking sites were first introduced. Lately, internet has caused a very long term drastic changes in peoples day to day life. It has made communication so much easier that its use is rapidly increasing and is affecting the population of all the age groups. The age group which is most affected are the teenagers. Internet has provided them with different recreational activities with the most popular activity called social networking.https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgEdUSiF8yVCqhKFnWtY__-d8GOJ6Yu-MQTl2OJkth_3lQTUTAelVLXQjR3_WoKXqA6Ot23fGA1y5Xw_RNIXeIfgZAkCpYf-f-OK_74jg8n8UEh7875au6G_M91keRNV9BIpauzaWzsXJc/s320/internet.gif à ¢- Ãƒ ¢- Ãƒ ¢-  Frequently children in 4th-6th grade levels engage in social networking activities. In the process they post personal, potentially exploitable, information about themselves online. Specifically, and within the last school year: 16% posted personal interests online, 15% posted information about their physical activities and 20% gave out their real name. In addition, 5% posted information about their school, 6% posted their home address, 6% posted their phone number and 9% posted pictures of themselves. This has led to child abuse which include kidnapping and raping that disrupts a kids childhood. à ¢- Ãƒ ¢- Ãƒ ¢-  Why I Chose This Topic? I chose this topic because in myself think that I have lately been using a lot of resources from internet for my educational work as well as recreation and fun. I have been using facebook very much lately and that has directly reflected on my grades in the exams that I gave lately. This addiction is so intense that I have to spend 2 hours of my time on facebook every day. So I have decided to research about how internet has affected my life? Global Perspective Internet gives us access to virtually unlimited amount of knowledge and information. The days are gone when teenagers had to flip through the books. Internet has made this very easier and books have been replaced by laptops and desktop-computers. These have made international cross communications very easier and have introduced different life concepts and cultures amongst the teenager who use internet. As the statistics suggests, 98% of the population aged from 18-24 uses social media too frequent in their day to day life. Worldwide, there are more than 1 billion user active users for the big three Microsofts Hotmail, Yahoo! Mail and Gmail. The international schools in MEDCs (more economically developed countries) like USA and UK encourage the use of internet widely in their type of teaching style. E-mails are used by students to make the communication easier, organised and faster for students and teachers both. GmailÆ’Â   425 million active users in June 2012 HotmailÆ’Â   350 million active users in October 2011 Yahoo MailÆ’Â  310 million active users in October 2011 More than 1.2 billion people across the globe uses worldwide social networking sites very frequently with most of them as children aged fewer than 20s. The survey of Rochester Institute of Technology states that 48% of students 2nd to 4th graders interact with people on social networking sites, while 50% indicate that their parents watch them when they use a computer and they have strict regulations over how to use internet and time limits for use of internet. But Harris Interactive-McAfee said that 63% of teenagers said that they know how to hide what they browse online from their parents. This suggests that the teenagers are slipping out of their limits and exploring data in the internet that they are not supposed to. Social networks are becoming more frequently used for dating purposes for teens. As suggested by Harris Interactive-McAfee survey, 52% of teens have given out personal information online to someone they dont know offline including personal photos and/or physical descriptions of themselves (24%). Statistics of the girls (34%) suggest that more girls have shared their personnel details than boys (15%). National Perspective- INDIA Introduction to diverse life concepts and cultures Development and introduction of internet through India has introduced many life concepts, different ideologies, cultures and different concepts on the very basic notion of how to live life. From cultures of the western world to cultures of remote civilizations,  it is said that the internet has made perception of life in general, extremely individualistic. Even if most of the Indian teenagers have not been abroad, but you can still see a part of them turning into western type culture. Exposure to vices and bad habits Internet is a pool of unlimited amount information. This cannot be always thought in a good way because this information portal has no device of filtering information for teenagers in India. Lets consider a typical global issue of pornography websites. Some of the websites have disclaimers which wares the user and warns them about what they are visiting because of the confirmation of age above 18 is asked. But is that working successfully to stop the teenagers from entering the adult websites? This was just an example. Indian teenagers have free access to information regarding drugs, sexuality and other ill habits that are condoned by the government of India. Concept of friendshipsC:UsersArjun DethaliaDownloads128863011033949093.png 1990: In these times, a friend was the one who youd meet regularly and have fun to gather. At last you would have many everlasting memories. And the communication took place through letters and telephones. When they part-away, there was agony of being separated because of no long distance communication as India was not developed in those times. 2012:  A friend is a person whose profile has been added to your profile and you know him by chatting or in neighbourhood. Communication with him/her takes place through chats and call. There is just a little feel of sadness when your friend drifts away because you could always stay in touch through social networks. Changing norms and traditions Internet has challenged the very thought of traditionalism of a cultural and religious India. In a land where culture, religion and values come before anything else in the world, internet is ruffling quite a few feathers -whether it is challenging traditions of how to build a house, how to use frozen food, how to live a nomadic life by taking backpacking trips or something as absurd as a woman looking up ways of becoming a pilot and a man looking up colleges to study catering. (Indonesia)Abductions and kidnapping have caused a large problem in countries like Indonesia. There have been several cases of kidnapping and child abuse there and police can really not do anything about it as the identity of the internet user is anonymous. Police is nearly impossible to find the culprit. Individual/ Local Perspective Rajkot is a city located in India, Gujarat. It is the 4th largest city in Gujarat and is one of the fastest growing cities in India. As it has gone through a rapid urbanisation, there has been a widespread use of internet since past 10 years. Internet has helped the teens of Rajkot transition in many different ways. Todays Teenagers of Rajkot uses technology more than they ever did. More than 80% of Junior-High students in TGS (The Galaxy School- one of the best schools in Rajkot) have internet access which they use to send and receive email, instant messages, live chat, and more. Well, the schools of Rajkot has tried to introduce education through internet amongst children from which TGS is has been extremely successful. Teens of Rajkot have nearly stopped hanging out with their friends because of internet because they could now; easily chat with their friends through live-chat/conference-calls. Online chatting also has its own hazards. Especially, when talking to strangers online they do not really know who they are. They can be just anybody pretending to be someone else. Many teens of Rajkot have been reported of child abuse and kidnapping happening this way!! And it has come hard on police as there is no way of verifying who have really done this. As far as I have researched, I have to agree that internet harms the teenagers more than they improve them. I am a teenager, 15 years old, and Internet has changed my life to a great extent. It provides me data that I can download and watch free without even paying for it in real life. I have a privilege to use internet whenever I want as far as I use it for something productive. As far as I have researched internet is bad for teenagers life and should be used in limited amounts a day or it could lead to addiction, a permanent physical disorder like weight gaining or could create a barrier between kids and their social life. Thus, I will try to cut down on my internet usage and will try to do my most of the work by many other authentic sources like books and articles. Possible Scenarios:- Cyber-Bullying Cyber-Bullying is a form of bullying that takes place over the internet that maliciously threatens a And humiliates the victim very badly. It was declared a serious crime by National Crime Prevention Council, in 2010.   It has extremely dangerous consequences like emotional distress to victims; from which depression has caused many deaths by suicides committed by youth. It is difficult to prevent as the criminal/s are anonymous and are hard to find. But if society takes necessary actions, the frequency of it occurring can be reduced. Friends and family of victims are also impacted when cyber bullying occurs. They may also feel powerless to stop it or guilty for not having spoken out against the bullying.   Ã‚   Social Development It has been proved that kids who spend more time on social networking cannot converse with people as well as who spend less. This is a real blow to kids development Children cannot therefore not socialize and blend with the people around them. Possible Courses of Action Kids under 15 are less stubborn and easy to control. Parents could just watch over them while they are browsing through internet for studies or anything else that is productive. They could be allotted with time to go online on social networks and chat with their friends or play games. Children that are over 15 are stubborn and are not as easy to control. So there are ways of watching over what they do on internet. Everything except the productive data on internet could be blocked using a software like Cyber-Roam Porn and drug trading is against the rules of using internet for teenagers. It is also legal to some extent in the developed countries. But it is still too harmful to get introduced in teens life. To stop the illegal activities happening on internet, sites that are for above adults should ask for a particular ID that proves that the person is above 18/adult. Drug trading online is illegal in each and every country of the world.

George Orwell, in his famous essay, â€Å"Why Socialists Don’t Believe in Fun,† aptly described the problem of any utopian ideal. â€Å"It would seem that human beings are not able to describe, nor perhaps to imagine, happiness except in terms of contrast†¦ Nearly all creators of Utopia have resembled the man who has toothache, and therefore thinks happiness consists in not having a toothache. They wanted to produce a perfect society by an endless continuation of something that had only been valuable because it was temporary† (Orwell).

If we analyze Raphael’s argument, we find that it is in effect duplicity. The assumptions made in both the construction of Utopia and the deconstructions of England’s economic system are both contradictory and completely over-simplified.
