Social Media - Essay Example Information sharing is considered as one of the major aspects of social media. The success of social media relies on the way people transmit and share information in an efficient manner (Panahi, Watson and Partridge, â€Å"Social Media and Tacit Knowledge Sharing: Developing a Conceptual Model†). Thesis Statement The report discusses the opinions of people on the usage of social media for sharing information. In order to understand the opinions about social media, two people have been interviewed on how they make use of social media for gaining information in one of the popular social networking sites named ‘Facebook’. The objective of the report is to recognize the importance of social media for sharing of information in present times. Information Sharing and Facebook Social media permits users to share their views, experiences, thoughts, understandings and perspectives effortlessly. Social media has opened new opportunities for users to involve in online groups and to develop media contents. Social media utilizes Web 2.0 application which has brought in a big revolution in the internet. Social media encourages sharing of information in a cooperative way. ... In these social networking sites people can establish relationships and influence social associations for sharing information and resources. In this context, it can be stated that Facebook is the biggest social networking site in the world (Wilson, Boe, Sala, Puttaswamy and Zhao, â€Å"User Interactions in Social Networks and their Implications†). It allows users to share basic information such as name, birthdate and other private interests. In Facebook, people use messaging applications in order to share information. Unlike other social networking websites, Facebook is developed by the model of networks which categorizes users to membership oriented groups. Users’ network membership enables to decide the type of information they can view and how their information is viewed by other people. Users can easily share photos and can post remarks (Wilson, Boe, Sala, Puttaswamy and Zhao, â€Å"User Interactions in Social Networks and their Implications†). Data Collectio n In order to understand the opinions of the people about information sharing in social media, two teenage students have been interviewed. The reason for selecting teenage students is that they are considered as the most active players in using social media and they also engage in social media activities frequently. Findings The interviewees were interrogated with close ended questions and open ended questions in order to understand their modes of using social media along with their thoughts about it for information sharing. The interview began with asking two questions concerning the frequency of using Facebook messaging and information sharing. It has been found that both interviewees use instant messaging on Facebook on a daily basis. With respect to sharing information both contribute

Alternatives to chlorine in waste water treatment: microfiltration, ultrafiltration, ion exchange

Sources Of Finance And Working Capital Management Finance Essay

Sources Of Finance And Working Capital Management Finance Essay In the financial context, the working capital management would include the management of debtors, creditors, stock, cash and bank account. This is a kind of short term financing as working capital management will cover current assets and current liability. It is one of the most important and time-consuming activities of the financial manager to ensure the solvency of the firm while attempting to maximize the firms value, there is a constant need to balance profitability and risk. Proper cash management plays an important part to meet permanent financing needs (pay creditors, pay taxes etc). few methods to ease the shortage of cash, such as postpone capital expenditure, negotiation with suppliers about the postpone or reduction of payment with extra caution as any in appropriate negotiation might hurt trading relationship. Furthermore, business can pay the creditor within the discount period so as to pay less to the vendor to enjoy discount, this is a kind of short term financing as it lower down the working capital. No any cost is carried with such kind of financing; business can enjoy higher profit but bear lesser risk. There are 3 basic financing strategies for working capital management to determine the appropriate mix of short-term and long term financing, which would consist of: the aggressive strategy, the conservative strategy and the moderate strategy. The aggressive strategy uses short-term funds to finance all of the firms seasonal and perhaps, a portion of its permanent needs, however, the cost and risk should be taken for consideration. Lower cost since short term financing cost is cheaper but higher risk as the net working capital is lowest. This may have difficulty in obtaining long term fund in an emergency when more financing is required. The conservative strategy uses long term fund to finance all of a firms projected needs and uses short terms funds only in emergencies. Higher cost is incurred since long term financing is more expensive and not needed all year long but low risk since net working capital is high, in addition, short term financing may be readily available in emergency. The moderate financing strategy is a compromise between the aggressive and conservative financing strategies. This result in a level of net working capital somewhat higher than that in aggressive strategy but lower than that of a conservative strategy. Question 2 There are different kind of financing sources which business can gather for its needs. There are four major types of financing such as government aid, business owners, borrowing from the bank and other way of borrowing. For short term financing, all kinds of business would like to borrow loan from the bank, industrial and financial institutions as HSBC (UK) help in promoting new companies, expanding and development of existing companies, providing underwriting facility, provision of local and foreign currency for the purchase of machinery. Commercial paper can be another type of financing which is an unsecured promissory notes issued by very large firms such as HSBC,GM as commercial paper is usually sold at a discount from its face value. Factoring and invoice discounting are the other 2 kinds of short term financing, which simply means that organisation get the advance cash by assign its debt or invoice to the factor, which normally can up to 80% of the value of debts or the amount of selected invoices. Business can through various forms to obtain the medium and long term financing such as debt financing, equity financing and others various forms. Debt financing is ideal for business as it is cheaper to use debt than other forms of financing because lender take lower risk than other long term contributors of capital, long term debts can be obtained through 2 ways: a term loan made by a financial institution such as HSBC which provides flexible business loan, repay over periods of 12 month to 15 years (10 years for fixed rate). The sale of bonds to institutional and individual investors, normally corporate bond are usually issued with maturities of between 5 to 30 years for raising large sum of money to meet its financing needs. Medium and long term financing are obtained through equity financing such as capital market and Initial public offering (IPO), through borrowing and selling shares, company can get much more cash which can be used for further development and other business opportunities. In addition, Listed company can also raise capital through issue right share which is relatively cheap and normally large amount of capital often be raised. Commercial mortgages offered by financial institutes would finance the business to buy freehold or long leasehold premise, for example: bank of Ireland offers flexible payment terms of up to 20 years with optimal repayments throughout the period of the loan. This would ease the tense of businesss medium and long term financing needs. Finally, a debenture is a long-term debt instrument which companies to obtain funds. A debenture is usually unsecured in the sense that there are no liens or pledges on specific assets. It is however, secured by all properties not otherwise pledged. This would satisfy corporate medium and long term financing needs. Question 3 Please refer to the appendix. (Excel format) Question 4 There is different tax liability applied for sole traders, partners and limited companies. For the sole traders, if he/she has any income from self-employment, then he/she should pay any Income Tax and National Insurance contributions due. This will depend on how much you earn from self-employment as he may have to pay Class 2 and Class 4 National Insurance contributions. Class 2 National Insurance contributions were charged at a flat rate, either by monthly Direct Debit or by quarterly bill. However, income Tax and Class 4 National Insurance contributions are based on sole traders profits from self-employment. There is several allowances for personal to claim, such as personal allowance, blind persons allowance, married couples allowance, maintenance payment relief, tax allowances and reliefs. Similar to sole trader, partners have to file an individual Self Assessment tax return. Moreover, partners have to fill in the partnership supplementary pages SA104. In addition, the nominated partner must also file a Partnership Return SA800 showing each partners share of the profits or losses. Supplementary pages might be included too, depending on what types of income the partnership has. The nominated partner is responsible for filing the partnership return but all partners will be jointly liable for any penalties, surcharges and interest if the return is late or inaccurate. Each partner is personally responsible for paying the tax and Class 4 National Insurance contributions due on their share of the partnership profits. Now comes to companies. From 1 April 2010, the corporate tax will be 28%, the taxation changes can be found in the appendix such as small companies tax rate is 21%. A non-resident company carrying on a trade in the UK through a permanent establishment located in the UK is liable to corporation tax on all income and gains attributable to that establishment. Corporation tax rates are fixed for each financial year ended 31 March. If the companys accounting period does not coincide with the financial year, its profits must be time-apportioned and the corporation tax rate is applied accordingly. Marginal relief applies to companies with profits between  £300,000 and  £1,500,000. The tax thresholds may be reduced where the UK Company has associated companies worldwide or an accounting period of less than 12 months. Large companies (broadly, those with profits taxed at 28%) are required to pay their tax to HM Revenue (HMRC) in instalments (generally in four equal instalments). The first payment is due six months and 14 days from the first day of the accounting period. There is a minimum limit which enables companies with an annual corporation tax liability of  £10,000 or less to avoid making such payments. For companies not required to pay their tax in instalments to HMRC, corporation tax is due for payment nine months and one day after the end of the companys accounting period Question 5 In the new tax incentive scheme, all business are eligible for the PIC( Productivity and Innovation Credit) for the year of assessment 2011 to 2015 if company invest in any one of following: Enhanced capital allowance or deduction for acquisition or leasing of prescribed automation equipment; Enhanced deduction of qualifying training expenditure; Enhanced writing-down allowance for acquisition of Intellectual Property Rights; Enhanced deduction of costs for registering certain Intellectual Property Rights; Enhanced deduction of qualifying research and development expenditure; and Enhanced deduction of qualifying design expenditure. Business can deduct up to 250% of their expenditure which incurred during these 5 years on each of these actitivities. Form the YA 2011 to 2012, a combined of 600,000 dollars of expenditure of each activity and 300,000 dollars of expenditure for YA 2013 to 2015 can be deducted from their income. In addition, businesses are eligible to convert up to $300,000 (but not less than $1,500) of the qualifying deductions for all six qualifying activities under the PIC   at a rate of 7% into a cash payout of up to $21,000 each year. This new scheme will promote business to invest most on machinery and train their employees to meet one national goal- more productive and innovative for the nation, for the worldwide competitiveness. For the new start up company, company can claim full tax exemption on the first 100,000 dollars of normal chargeable income and 50% for the next 200,000 dollars. This scheme will support local entrepreneurs and help local business grow as the starting of business is always difficult. Other common expenses or tax incentive companies can enjoy are: business expense, capital allowance, industrial building allowances, land intensification allowance, loss carry-back relief and unutilised losses, capital allowances and donations. Question 6 Problem 2 500,000=100,000+150,000+250,000 The payback period is 3 years. Year Cash Flow PV of Cash Flow Cumulative 0 -500,000 -500,000 -500,000 1 100,000 100,0000.9009=90090 -409910 2 150,000 150,0000.8116=121,740 -288170 3 250,000 250,0000.7312=182,800 -105,370 4 300,000 300,0000.6587=197,610 PV=FVx(PVIFn,11%) The discounted payback period=3+ 105,370/197610=3.53years Since 3 Problem 4 a) Year Cash Flow PV of Cash Flow 0 -225,000 -225000 1 75,000 75,0000.8547=64,102.5 2 125,000 125,0000.7305=91,312.5 3 200,000 200,0000.6244=124,880 (total)=280,295 PV=FVx(PVIFn,17%) NPV=280,295-225,000=55,295 b) PI= 280,295/225,000=1.26 c) The project should be accepted as a profitability index greater than 1 and there is consistent with a positive net present value, 1.26 indicates that company can earn the 17% of required rate of return, plus provide a net present value of $ 0.26 per $1.00 of net investment. Problem 6 Year Cash Flow PV of Cash Flow 0 -875,000 -875,000 1 400,000 400,0000.8850=354,000 2 500,000 500,0000.7831=391,550 3 600,000 600,0000.6931=415,860 Total=1,161,410 NPV= -875,000+400,000/(1+r)+500,000/(1+r)2+600,000/(1+r)3=0 IRR=30% Beginning Value=875,000 Terminal Value=354,000+391,550+600,000=1,345,550 So: MIRR=24% 24%>13% and 30%>13%, so we should accept the project. Question 7 There are several technique of financial appraisal, such as NPV, IRR,payback period, discounted payback period etc. Both NPV and IRR generate same accept/reject decision at given cost of capital but may rank project differently due to underlying assumptions such as NPV assumes cash flow are reinvested at the cost of capital( k is from funding), IRR assumes cash flow are reinvested at the internal rate of return itself( k is for project), thus the magnitude and timing of cash flows will affect the ranking of the projects. Theoretically, NPV is superiors than IRR as it assumes cash flow s are reinvested at the cost of capital which is more realistic than being able to reinvest at a higher rate( usually) in the IRR. Thus, NPV will be more effective to measure project prospect. There are a number of projects for which using IRR is not as effective as using NPV to discount cash flows. IRRs major limitation is also its greatest strength: it uses one single  discount rate to evaluate every investment. Practically, IRR is superior, as it is easier to understand, though more difficult to calculate as trial and error approach is used to find the IRR. The NPV method is inherently complex and requires assumptions at each stage discount rate, likelihood of receiving the cash payment, etc. The IRR method simplifies projects to a single number that management can use to determine whether or not a project is economically viable. The result is simple, but for any project that is long-term,  that has multiple cash flows at different discount rates, or that has uncertain cash flows in fact, for almost any project at all simple IRR isnt good for much more than  presentation value, therefore, IRR is less effective than the NPV. For payback period method, there are two main problems associated with it: It ignores any benefits that occur after the payback period and, therefore, does not measure profitability and ignores the time value of money. Whereas for discounted payback period method, it considers the time value of money and the riskiness of the projects cash flows (through the cost of capital) but no concrete decision criteria that indicate whether the investment increases the firms value and it requires an estimate of the cost of capital in order to calculate the payback and ignores cash flows beyond the discounted payback period. In general, each method has the certain extent of effectiveness on project prospect measurement. Question 8 a)Current ratio = Current Assets/Current Liabilities = 146,438,269/220,500,307 = 0.664 A ratio of 0.664 means that for every $1 owned by the firm, it has $0.664 of current assets that can be converted into cash to meet these debt obligation, so company can not cover its debt now. b) Quick ratio = (CurrentAssets-Inventory-Prepaid Expenses)/Current Liabilities = (146,438,269-59,716,920)/ 220,500,307 = 0.393 A ratio of 0.393 means that each dollars of short-term debt is backed by $0.393 of cash or near-cash assets. c) Inventory Turnover= Cost of Goods sold/Ending Inventory =333,027,693/59,716,920 =5.577 A ratio of 5.577 times means that during the year, on the average, the company sell its inventory 5.577 times. Number of days it takes to sell its stock are 365/5.577=65.4. d) Profit Margin =Gross Profit/Net Sales =65,423,180/1,254,805,671 =0.052 $1 net sales generate $0.052 towards covering operating expenses and the excess contribute to net profit. e) Return on assets =Net operating profit before interest/ending total assets = (44,815,036+41,737,790)/1,612,578,813 =0.054 Every $1 asset generates a profit of $0.054. f) Return on common stockholders equity = net profit after tax/ending ordinary stockholders equity = 44,815,036/516,770,461 =0.087 It means that every $1 invested by the ordinary stockholder earns a net profit of $0.087 g) Debt to total asset ratio =total liabilities/total asset =1,095,808,352/1,612,578,813 =0.680 It means that 68% of the total asset are finance by borrowing as the percentage of assets financed by creditors increases, the riskiness of the company increases. h) Times interest earned = (Net profit before deducting interesttax/interest expense = (44,815,036+41,737,790)/ 41,737,790 =2.074 It means that recurring income is 2.074 times of interest payment. i) Asset Turnover =revenue/total asset =1,254,805,671/1,612,578,813 =0.778 This means that companies with low profit margins tend to have high asset turnover, it indicates pricing strategy. This ratio is more useful for growth companies to check if in fact they are growing revenue in proportion to sales by 0.778 times. ( 2497 words)

Ceci est en effet la question. Nous sommeschargà ©s danalyser si cette colonisation, bien quelle fut forcà ©e, avait un butcivilisateur ou destructeur. Cest une question dà ©licate que nous allons tenterde rà ©soudre laide de faits historiques, opinions dhistoriens et dephilosophes, ainsi qua laide du point de vu de recul que nous avons obtenu auvingt et unià ¨me sià ¨cle. II.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Bref historique Il est important,tout dabord, de se remà ©morer certains faits historiques. La conquà ªte delAlgà ©rie dà ©buta en 1830 par le roi Charles X pour raisons de piraterie. Cenà ©tait pas une invasion objective et sans provocation comme celle, parexemple, des Amà ©riques par les Espagnols et de lInde par les Anglais. Apres lapremià ¨re expà ©dition punitive qui ne fut chargà © que de se saisir les zonescà ´tià ¨res, la France se rendit vite conte des ressources prà ©cieuses quoffraitce nouveau territoire et la situation fut irrà ©mà ©diablement changà ©e. Apres prà ¨sde quarante ans de batailles, les diffà ©rents gouvernements locaux du territoirealgà ©rien se montrà ¨rent favorables a une assimilation partielle. Cest alors quecommena la colonisation de lAlgà ©rie par la France, un expansionnisme qui nesacheva quen juillet 1962. Ce fut une occupation mouvementà ©e, secouà ©e pardeux guerres mondiales et une guerre civile entre les colonisateurs et leurscolonisà ©s. Un pays maintenant autonome et modern, lAlgà ©rie fut nà ©anmoins unpays contrà ´là © par de nombreux mouvements terroristes, surtout dans les annà ©escinquante, qui se dissolurent rà ©cemment aprà ¨s de longs pourparlers. Nous avonsdonc un pays moderne mais avec une histoire complexe, un exempleparticulià ¨rement intà ©ressant de colonisation ambiguÃÆ' « par un pouvoir europà ©en. III.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Une mission civilisatrice Tous pays colonisateurs a travers les sià ¨cles occupà ¨rentdes pays à ©trangers en professant un but trà ¨s clair; apporter la civilisation aubarbares. Mà ªme si de, nos jours, nous pouvons analyser les intentions derrià ¨reces excuses, les progrà ¨s en mesure dà ©ducation, dorganisation gouvernementaleet de dà ©veloppements à ©conomiques et culturels sont indà ©niables. Quelques lignesdans les carnets personnels de Victor Hugo lui-mà ªme, sous la monarchie dejuillet, le font apparaà ®tre comme ferme partisan de la colonisation  ; ,Lacolonisation militaire doit couvrir et envelopper la colonisation civile commela muraille couvre et enveloppe la cità ©. La colonisation militaire, cest unemuraille vivante. Quel meilleur obstacle continu quun camp franais? Mettez lesoldat en avant du colon comme vous mettez un fer au bout dune lance . Considà ©rons donc tout dabord les effets positifs de lacolonisation franaise en Algà ©rie, les aspects civilisateurs de cette missionqui permirent un pays aussi grand de se dà ©velopper et de devenir un pouvoirà ©mancipà © et moderne dans le contexte politique actuel. Premià ¨rement, la Francedivisa lAlgà ©rie en provinces et en communes, instaurant la structure à ©laborà ©epour la France par Napolà ©on, organisant le pays pour une meilleure rà ©gence.Ceci unifia en un à ©norme territoire un pays qui, jusqualors, ne fut quuneagglomà ©ration confuse de tribus qui ne communiquaient pas entre elles, quinavaient pas didentità © nationale. Un dà ©veloppement à ©conomique accà ©là ©rà © fut à ©galement unaspect de la colonisation qui profite lAlgà ©rie moderne. Loccupation franaisepermis de fortifier le pays à ©conomiquement en à ©duquant, comme le systà ¨medà ©ducation franais  lavait fait en Tunisie et au Maroc, une partie de lapopulation pour des formations dà ©ducateurs et dingà ©nieurs. Cette classeà ©duquà ©e pu, aprà ¨s lindà ©pendance, continuer lextension à ©conomique de leurpays. Le pays pris connaissance de ses ressources naturelles et desdispositions furent prises pour les exploiter. La langue officielle à ©tait lArabe mais la languediplomatique vite devint le Franais. La loi du 26 avril 1968 aprà ¨slindà ©pendance rendue la connaissance de lArabe obligatoire pour lesfonctionnaires. Daprà ¨s le Cite du Continent Africain, aujourdhui, la majorità ©des Algà ©riens sont arabophones dans une proportion de 72%, mais cette pà ©riodedoccupation permis bel et bien au peuple algà ©rien de devenir bilingue. De pairavec linsertion de la langue franaise, la colonisation de LAfrique du Nordpar la France permis le dà ©veloppement dune culture franco-algà ©rienne unique.Là ©ducation francophone eue un autre aspect positif dans le dà ©veloppement de laconscience algà ©rienne vis a vis du reste du monde les notions de peuple,didentità © et de nationalisme qui, ultimement, servirent la libà ©ration delAlgà ©rie, furent inculquà ©es aux enfants algà ©riens qui devirent la gà ©nà ©rationindà ©pendantiste. IV. Une mission exploitative Nous allons maintenant examiner les aspects exploitatifs dela colonisation algà ©rienne par la France, car mà ªme aprà ¨s lexposition desaspects civilisateurs de cet impà ©rialisme, il est impossible dignorer lesprofonds changements nà ©gatifs quapportà ¨rent la conquà ªte franaise nonseulement à ©conomiquement, mais à ©galement concernant le mode de vie algà ©rien. Comme lexplique tout dabord Mohammed Harbi danslinterview   LAlgà ©rie malade de son passà ©?  , non seulement lespetites tribus rurales algà ©riennes on perdu leur richesse culturelle pour causede la colonisation franaise, mais la reconstruction du pays fut rà ©servà ©e a uneà ©lite culturelle blanche  ;   Les relations tribales ont à ©tà © brisà ©es,les ruraux ont perdu leur identità © et leur richesse. Par ailleurs, a ladiffà ©rence de ce qui sest passà © en Tunisie et au Maroc, la France limitalà ©mergence de cadres pouvant reprà ©senter là ©gitimement  la socià ©tà ©.   Nous voyons ainsile dà ©veloppement inexorable dà ¨s 1830 de la pauvretà © des indigà ¨nescomparà ©e la prospà ©rità © presque illimità ©e des colonisateurs. Mà ªme aprà ¨slindà ©pendance en 1962, cest une à ©lite algà ©rienne, exclusivement citadine,à ©duquà ©e le plus souvent a Paris qui, une fois de plus, dirigea le pays audà ©triment des minorità ©s ethniques du s ud du pays. Similairement, pendant queles franais et autres europà ©ens   occupaient les villes et les meilleuresterres, disposaient dà ©coles, de routes et de services publics efficaces,lAlgà ©rie musulmane habitait les bidonvilles   et devaient se satisfairedes moins bonnes terres ainsi que de pires emplois au service de leurscolonisateurs. Nous savons ceci daprà ¨s les faits historiques, mais il estaussi vrais que certains colons traità ¨rent leurs ouvriers algà ©riens dignementet avec respects. Ces franais qui virent dinstaller en Algà ©rie avec leurfamille et refusà ¨rent de quitter leurs terres avant et mà ªme aprà ¨s la guerrecivile furent souvent rituellement massacres. De plus, la situation politique est restà ©e trà ¨s tendue etviolente aprà ¨s lindà ©pendance. Les historiens et philosophes actuels, commeGeorges Hardy dans son livre Histoire Sociale de la colonisation franaise,ne cessent de se demander si lAlgà ©rie a tellement lhabitude de se battrecontre des forces doccupations quelle ne sait pas sarrà ªter. La colonisationa t-elle laissà © derrià ¨re elle un là ¨gue de violence? Les partis nationalistes duFLN (Front de Libà ©ration Nationale) et de lUDMA (Union Dà ©mocratique duManifeste Algà ©rien) furent trà ¨s actifs entre 1954 et 1999, dà ©chirant le paysavec de conflits politiques dans lesquelles les France ne pouvait là ©gitimementprendre parti ou se mà ªler. La France imposa en 1887 a LAlgà ©rie, ainsi qua toutes sescolonies, le Code de lIndigà ©nat. Daprà ¨s Fà ©licien Callaye dans Le livrenoir du colonialisme, le code dà ©pouillait les colonisà ©s franais de leurslibertà ©s, linterdiction de circuler la nuit par exemple. Ce code distinguaitaussi deux catà ©gories de citoyens; ceux de souche et les sujets. De mà ªme,nous avons en effet dà ©j commentà © sur le fait que la langue franaise devint lalangue officielle, poussant ainsi tout algà ©rien a devenir bilingue, mains nousnavons pas encore observà © que cette langue devint quasi-exclusive danslAdministration, lenseignement ainsi que laffichage. Une loi franaise en1938 dà ©clara mà ªme lArabe comme à ©tant une langue à ©trangà ¨re en Algà ©rie. Ceci estun exemple classique dimposition de culture. Le dernier cas dexploitation, et peu à ªtre le plus connucar il est le plus rà ©cent, fut le recrutement dindigà ¨nes en masse pendant lesPremià ¨re de Deuxià ¨me Guerres Mondiales.   Lors de la Premià ¨re Guerremondiale, le recrutement indigà ¨ne fournit 173 000 militaires Au mà ªme moment,quelque 119 000   travailleurs   Algà ©riens vinrent travailler enmà ©tropole  .Pour la seconde guerre mondiale, plus de douze mille soldats algà ©riens durenttuer pour la France. Ce pays fut appelà © soutenir un combat qui nà ©tait pasmoralement le sien. Il est incroyable que, aprà ¨s tout cela, le General deGaulle du se battre pour faire comprendre aux dirigeants et au peuple franaisque lAlgà ©rie mà ©ritait son indà ©pendance. Les bà ©nà ©fices de la colonisation pour la France jusqulindà ©pendance furent à ©normes. LAlgà ©rie disposait et dispose dailleurstoujours de ressources naturelles exceptionnelles: elle est au cinquià ¨me rangdes rà ©serves mondiales de gaz naturel et possà ¨de à ©galement des grandes rà ©servesde pà ©trole. Le dà ©veloppement industriel du pays facilita lextraction de cesressources, ainsi que la facilite dobtenir de la main d-uvre payà ©e dessalaires exploitants. Daprà ¨s Gille Manceron dans sont livre Marianne et lesColonies, mà ªme les intellectuels et politiciens franais se montrà ¨rentcomplices en gardant le silence  ;   Sous la monarchie de Juillet, lesdà ©nonciations de la conquà ªte de LAlgà ©rie apparaissent assez isolà ©es. On trouveparfois une certaine rà ©probation de la violence coloniale chez les responsablesde lopposition dà ©mocrate, mais la plupart dentre eux se rallient tacitementou explicitement au projet colonial.   V. Conclusion: une mission largement exploitative Nous savons maintenant toute là ©tendue des barbarismesopà ©rà ©s pendant la guerre dAlgà ©rie par les soldats franais qui, en grandepartie, avaient reu des ordres directs de leurs gà ©nà ©raux. Les documentssecrets retenus pas la Dà ©fense Nationale viennent rà ©cemment dà ªtre renduspubliques aprà ¨s leurs cinquante ans mandataires. La prolifà ©ration de la torturede 1954 a 1962 reprà ©sente pour beaucoup lultime recours de la France pourexploiter, une dernià ¨re fois, les ressources algà ©riennes. Ceci à ©choua. Maispour beaucoup cette exploitation nest pas finie. Le gouvernement actuel dirigà ©par Abdelaziz Bouteflika rà ©Ãƒ ©lu en avril 2004 avec le soutient de Jaques Chiracest considà ©rà ©, par une grande partie de la communautà © politique nationale etinternationale, davoir truquà © les à ©lections prà ©sidentielles. La dominancedune minorità © soutenue par la France est aussi considà ©rer comme à ªtre largementresponsable de la dà ©sastreuse à ©co nomie actuelle.

Benefits and Hazards of Immunizations Essay -- Science Scientific Pape

Benefits and Hazards of Immunizations Although science and technology have been very beneficial to us a lot of people are misinformed about its procedures. I myself am a bit fearful about how technologically advanced we're getting in such a short period of time, but this is because I don't understand science. I guess most people that fear science feel that way because of the horrible things that science may bring about. When reading Mary Shelley's "Frankenstein" one begins to wonder what if scientists do create a monster and like Dr. Frankenstein did, can no longer undo the creation. It is actually a very scary thought. But then on the other end of the spectrum you have J. Michael Bishop who defends scientists against people's critiques. Bishop is correct in his argument that scientists have done great things. According to him, people begin to lose faith in science because they don't see results as fast as they would like to but as Bishop states research may take years and even then, there may not be a concrete answer. T he important thing is that they are working towards one and people should not expect miracles, they should allow scientists to do their work and only hope for a quick solution. When dealing with a situation of whether science has benefited or troubled the population we can talk about immunizations. Immunizations have saved many children's lives. The epidemic of polio is hardly heard of thanks to immunizations. Measles and chicken pox don't affect children half as much if they've had the immunizations either. So one can say that immunizations have been a benefit to the population because most, if not all, children in the United States have gotten the required vaccines and nearly all of them go away from the... ...ants everybody to get the vaccine, because as statistics show, the majority of the children are perfectly fine after immunizations. The problems that are arising with vaccines shouldn't be blamed on scientists, for they've come up with a solution to the mentioned illnesses. The problem may be in the way doctors are combining vaccines, or implementing them. Works Cited Bishop, J. Michael. "Enemies of Promise." The Presence of Others 3rd edition.

FINDING THE CONCLUSION :: essays research papers

Background   Ã‚  Ã‚  Ã‚  Ã‚  Critical thinking can be used in certain aspects of problem solving and requires various types of skills. People must be motivated and not afraid to use their critical thinking skills to solve various troubles that can and will arise. Problem Statement What are the issues and the conclusion? We as readers and listeners in today’s society always seem to believe everything that we read and hear without digging a little deeper to actually find out if it is the truth. Analysis Critical thinking is a skill that we are not born with, but with some knowledge and practice it is a tool that can be used very effectively. Becoming a critical thinker takes time, practice and lots of thought. We as humans always try to force our view upon other people and of course we assume that we are always right. From the other perspective when we have an opinion forced upon us we naturally get defensive. We as critical thinkers need to be open to other people’s opinion but listen with caution to all of the facts before we make any assumptions or judgments. Recommendations 1.  Ã‚  Ã‚  Ã‚  Ã‚  Don’t always believe everything that you hear and always ask yourself what the issue is. 2.  Ã‚  Ã‚  Ã‚  Ã‚  Always try to find the conclusion and look for indicator words. 3.  Ã‚  Ã‚  Ã‚  Ã‚  Remember what the conclusion is not. Conclusions will not be any of the following: a.  Ã‚  Ã‚  Ã‚  Ã‚  Examples b.  Ã‚  Ã‚  Ã‚  Ã‚  Statistics c.  Ã‚  Ã‚  Ã‚  Ã‚  Definitions d.  Ã‚  Ã‚  Ã‚  Ã‚  Background Information e.  Ã‚  Ã‚  Ã‚  Ã‚  Evidence S.W.O.T My selected recommendation is: †¢Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Don’t always believe everything that you hear and always ask yourself what the issue is. Strengths †¢Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Understanding and listening will make you more aware of the real issue and will help you become a better critical thinker. †¢Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Learning to listen will help you in many aspects of not only your personal life but it can be a very strong aide on your professional life. Weakness †¢Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  We can become very skeptical about everything. Sometimes we need to sit back and ask ourselves when is critical thinking necessary. †¢Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Critical thinking is a very powerful tool and used for the wrong purpose you can damage ones character. Opportunity †¢Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  We as critical thinkers have the opportunity to see things very clearly and realize when the wool is being pulled over our eyes.

Nanotechnology in Medicine

Nanotechnology in Medicine When thinking of Nanotechnology one could think of the movie G. I. Joe: The Rise of Cobra. In the movie Cobra steals nanotech warheads and attacks the Eiffel Tower and it is destroyed by molecule sized machines in a matter of minutes. At this point in time nanotechnology is nowhere near this far along. Nanotechnology of today is about manipulating different types of matter on a molecular scale thus making them stronger and more durable (Williamson, Kenneth D. New Products). Hopefully we’ll be able to create the nanobots of G.I. Joe in the near future but for now it is just science fiction. With the science of nanotechnology we can revolutionize the field of medicine like never before, destroy cancer in the human body without killing the host body and revolutionize diagnostic imaging technology. Nanotechnology in medicine is often referred to as Nano medicine. One of the first uses of nanotech in medicine was in the early nineties. Silver Nano crystal s were developed and used as an ant-microbial agent in healing infections (Nanotech in Med. ilver coatings). Another use is in burn treatment. The burn dressing applied to burns is loaded with nanoparticle sized antibiotics that are released when encountering a foreign organism (Nanotech in Med. ) Another positive use for preventative care is the use of â€Å"Buckyballs†. Buckyballs are an accidental discovery made by Richard Smalley in the early 1980s; they are a form of carbon which has been found to be able to purify any kind of water thus preventing people from catching water borne sicknesses (Nanotech’s Impact).Currently the fight against cancer uses the bloodstream as the delivery system for toxic drugs. A cancer patient in the process of taking these drugs is subjected to a mind numbing array of horrible side effects. In 2012 a company, Bind Biosciences submitted clinical data on their use of nanotechnology to fight cancerous tumors. Their data shows that more o f the cancer drug is delivered to the tumor and that there were marked improvements in anti-tumor activity. This process also reduced the toxicity to the patients and there was no new toxicity problems noted (Clinical Data.Bind 014). This process will eventually be able to be used with all cancer types as soon as the process is approved. In the past it was hard to determine the exact position and shape of cancer tumors and impossible to deliver cancer fighting drugs to the tumor itself. With the advancement of diagnostic imaging it is now possible to deliver these drugs directly to the tumor itself. Now a person is injected with or drinks something infused with nano-particles and allows scientists a sharper image of the person’s body (Nanotech. Emerging Tool).When patients drink the dye for M. R. I. imaging the dye wouldn’t last. Now the nano-particles being used have a long shelf life inside the body and can be used in subsequent imaging sessions (Nanotech. Emerging T ool). With nanotechnology it is also possible to track an individual cell through its journey in the body (Nanotech. Emerging Tool). At this time the United States of America has invested three point seven billion dollars in its own nanotechnology program and most other developed countries are following suit (Nanotech. Wikipedia).Within the next fifteen years there are going to be some major leaps in technology due to the use of nanotechnology and the human life experience is going to be better than ever before in human history. It is already changing life as we know it and most people don’t even realize it.
