A Solution For South African Energy Crisis Environmental Sciences Essay

This study investigates assorted sustainable energy beginnings in order to set up which beginning would be most dependable to run into the electricity demand of South Africa. Hydro-energy, air current energy, ocean current energy and solar energy were studied. Although an substructure already exist, for air current energy the study concludes that solar energy would be the most dependable renewable energy beginning. Modern societies across the Earth are dependent on the handiness of dependable electricity supply for the care of human and economical activities. Worldwide people are hence progressively concerned about the handiness and the sustainability of energy beginnings for the coevals of electricity. Presently in South Africa the topic â€Å" sustainable energy † is besides high on the docket. This study will look into the place of electricity supply in South Africa and the possible solution that sustainable energy beginnings might keep for South Africa. This study will foremost give a historical overview of the origin and the development of the electricity supply industry in South Africa. Then it will look briefly at the complex inquiries that electricity providers have to face. Finally the assorted types of sustanable energy applicable to South Africa, viz. hydroenergy, air current energy, ocean current energy and solar energy will be discussed.2 Historic overviewThe history of the origin and development of the Southern African electricity supply industry is a absorbing topic. The proficient challenges, the interaction with Industry every bit good as political leaders is non new, but has been portion of electricity from the exchanging on of the first street visible radiations on the African continent in Kimberley on 1 September 1882, three yearss before the launching of the first commercial power station in New York. The history of sustainable energy in South Africa is in fact longer than most people would conceive of. Already in 1895 there were attempts to tap the hydro-energy potency of the Victoria Waterfalls. In 1895, forty old ages after Livingstone had discovered the Victoria Falls, Professor George Forbes arrived in Southern Africa. He was the interior decorator of the Niagara Falls Hydroelectric Power Station, which was at that clip the largest power strategy in the universe. With the Victoria Falls, non merely every bit broad as Niagara, but with dual the tallness, he could non neglect to be impressed by its possible as a hydroelectric strategy to provide the Witwatersrand with an abundant and inexpensive supply of electricity. Although the chief obstruction came in the signifier of the 1 000 kilometer distance over which the power had to be transmitted, a subordinate called the African Concession Syndicate was created in 1901. This mob was granted the exclusive right to tackle the Zambezi River for present and future hydroelectric power strategies. In malice of these readyings, the usage of H2O in the coevals of electricity would merely come much later ( Conradie & A ; Messerschmidt, 2000 ) .3 The complexnesss of electricity systemsDuring the argument in the media around the current crisis a few affairs became clear. First, it is non widely understood that electricity can non be stored and in the instance of renewable energy beginnings, that becomes a major challenge. The 2nd complexness that was ( and still is ) non widely understood, is the complex workings of the electricity supply. The coevals of electricity from power Stationss which are largely situated in the northern inside of the sub-continent and conveyed to the client by manner of 28 000 kilometer of high electromotive force and 250 000 kilometer of lower electromotive force lines, is besides hard to understand. The reconciliation of changing supply and demand requires the changeless attending of the National Control Centre and if the demand outstrips the supply, it is possible to see entire electromotive force prostration, similar to the state of affairs in the north eastern American continent on 14 August 2003 when the consecutive tripping of power lines by trees under power lines in three different countries lead to a electromotive force prostration of the transmittal system. This plunged big metropoliss like New York and Washington in partial darkness and metropoliss like Toronto in entire darkness. The full Restoration of the power system took about a hebdomad to finish. The term â€Å" burden casting † ( besides non understood by most ) is used to denote the sloughing of burden or electricity demand in order to forestall the 50 Hz frequence from dropping excessively low, ensuing in under-frequency tripping of power Stationss and entire electromotive force prostration.4 Sustainable energyFor many old ages South Africa has been, and still is, bring forthing some of the cheapest electricity in the universe. This was mostly due to the handiness of really inexpensive low class coal. With the lifting demand in the remainder of the universe for that coal, South Africans will decidedly experience the pinch. Because of this state of affairs the natural response is to look at pull offing the demand for electricity every bit good as investigate renewable energy beginnings. As can be seen in Figure 1, a figure of sustainable energy beginnings have been identified in the universe. These beginnings can be classified harmonizing to the type of energy they produce. The challenge for South Africa is to use those beginnings most fitting for the fortunes here. Figure 1: Sustainable energy beginnings identified worldwide ( Beginning: Renewable energy. The possible and the restrictions. 2008. [ Online ] . Available: hypertext transfer protocol: //www.fraw.org.uk. [ 2009, December 15 ] . ) Two chief issues need to be considered when looking at the viability of alternate energy beginnings. The first is of class the proficient feasibleness of the undertaking. The 2nd is the cost at which electricity can be produced by the alternate beginning.5 HydroenergyOne of the most obvious renewable beginnings is hydroenergy. In many states, particularly in the Northern hemisphere, many electrical public-service corporations produce power in this manner. In the instance of South Africa, the state does non hold big rivers that can be used to bring forth electricity with.6 Current usage of hydroenergy in South AfricaAt this phase Eskom operates a figure of pump storage strategies that pump H2O into keeping dikes during off-peak periods and usage that to bring forth power during extremum periods. As such this is non a renewable beginning as it uses electricity from dodo fuelled power Stationss for pumping H2O.7 The Congo river as the energy provider for Southern AfricaOne instead ambit ious undertaking that Eskom is presently involved in is to use the hydroenergy from the Congo River. Harmonizing to its inaugural one-year study, the Western Power Corridor ( PTY ) Ltd ( Westcor ) ( 2008 ) proposes to tap the rich, big graduated table renewable hydroresources of the Western, Central and Eastern Corridor of Southern Africa finally. When to the full tapped, the magnitudes will transcend 100GW. This joint venture between the take parting national state-owned electricity companies of Angola, Botswana, Democratic Republic of Congo, Namibia and South Africa was signed on 7 September 2005 in Gabarone, Botswana. Harmonizing to Mr E Nelumba, Chairman of the Shareholders Steering Committee, Westcor was formed to develop the Western Power Corridor which includes the development of the 3 500 MW tally of river hydroelectric power works at Inga 3 in the Democratic Republic of Congo ( DRC ) . It will besides build power transmittal systems to incorporate with the national grids of the participating every bit good as the remainder of southern Africa. The concluding aspiration is to bring forth 10 000 MW at Inga 3. The Congo River has an estimated 100 000 MW capacity with 40 000 M3s per second and all possible sites are under examination to finally make the end of 50 000 MW of Grand Inga. This is larger than the sum installed capacity of the full Eskom system. Angola has besides indicated that their exploitable hydroelectric potency is about 18 000 MW of which merely 810 MW is presently used. One of the great challenges of this undertaking remains the transmittal of the power to the chief clients in the South. In order to reassign the power faithfully and economically it would be necessary to run the 4 000 kilometer power lines at electromotive force between 600 kilovolts and 1000 kilovolt. The engineering to be able to make this is still in its babyhood and is the topic of current research. To add to the quandary the environment that the proposed lines will track includes countries with some of the highest happening of veld fires and these have the ability to do breaks to the flow of power.8 Wind energyThe usage of air current as an energy beginning is likely one of the best known signifiers of renewable energy and successful commercial operations have been around for a long piece. Harmonizing to the IngenierbAA?ro fAA?r neue Energien air current coevals in Germany sums to 39 500 GWh ( Power in Europe, 2008 ) . This accounts for more than half of the renewable energy in that state. The universe ‘s entire installed capacity of air current generators was 94 GW at the terminal of 2007 ( Smit et Al, 2008 ) .9 Wind turbines in usage presentlyEskom commissioned three wind turbines between August 2002 and February 2003 at its Klipheuwel site North of Cape Town. Two Danish turbines and one French turbine, with a combined capacity of 3.16 MW, were installed to enable Eskom to compare the different design and operational features. To day of the month the installation has generated more than 15 GWh, which was fed into the grid at the Klipheuwel 11 kV/66kV substation ( Smit et Al, 2008 ) . The single power, responsibility rhythm and cost features of each of the turbines are being collected in a engineering matrix that will finally incorporate a suite of Renewable Energy engineering options, with air current being the first. The tower dynamic features and quiver status supervising baseline measurings every bit good as the interaction between the grid and the generators have already been done. The production analysis will be used in the future selling of green energy ( Smit et Al, 2008 ) .10 Variability in available energyAs with other signifiers of renewable energy, the variableness in the available energy is an issue that concerns the developers of these systems. Wind is no exclusion and in this instance an accurate finding of air current climatologies is required, based on several old ages of air current informations. A well-known survey carried out by Geernaert et Al ( 1988 ) used information of a 109 old ages ( between 1873 and 1982 ) and showed that fluctuations of up to 30 % from the average value can be expected from one decennary to the following. This information is important if it is considered that the installation may hold a lifetime of 20 old ages and longer. The available air current energy is of class besides influenced by topographical factors every bit good as variableness in air current speed due to height fluctuations. This makes the pick of the appropriate site a really of import issue.11 The hereafter of air current energyWith the valuable research done at Klipheuwel the hereafter for air current coevals seems bright. Eskom announced the building of a 100 MW installation on the West Coast close to Koekenaap in 2007. The EIA and commercial activities are good underway and building is planned to get down tardily in 2008. The installation will dwell of approximately 50 units runing between 1.5 to 2.5 MW and will be integrated into the 132 kilovolt system at Eskom ‘s Juno or Koekenaap substations. Based on the variableness d iscussed above and an energy use factor of 26 % , the installation is expected to bring forth 2 28G Wh per annum ( Smit et Al, 2008 ) . Based on old experience the building of the installation will take about one twelvemonth to finish.12 Ocean current energyThe energy fluxes of the oceans have attracted the attending of applied scientists for a long clip and include the assorted signifiers.13 Continual moving ridge gestureThe continual moving ridge gesture that can power coevals devices. One illustration is the US $ 29.5m experimental installation of Scots Power at the Orkney Islands ( Power in Europe, 2008 ) . The Pelamis system consists of four elephantine metal â€Å" sausages † , each 450 m long, bobbing on the moving ridges and each bring forthing 750 KW by turning the gesture into electricity via the pumping of hydraulic fluid through the articulations. By some estimations Scotland should be able to bring forth every bit much as 1 300 MW by 2020.14 Tidal energyThe gravi tative forces of the Sun and Moon consequence in the surface of the sea changing by about 2 m. This consequence can be amplified by up to 11 m due to the effects of bays and channels. It is this energy that is used by systems such as the tidal energy works at La Range in France with a capacity of 240 MW.15 Salinity differencesAlthough the salt differences between the ocean H2O and fresh overflow represent differences in chemical potency which may be harnessed through a suited membrane, this has merely been demonstrated on a little graduated table.16 Thermal differencesThe thermic differences between surface and deep H2O can be every bit much as 15 grades and a heat engine can be used to bring forth power. This construct, referred to as Ocean Thermal Energy Conversion ( OTEC ) has, nevertheless, a thermodynamic efficiency of merely 8 % and Eskom is presently measuring the usage of cold deep H2O as a coolant for coastal power Stationss, where its efficiency will be higher.17 Fast flux ing ocean currentsThe fast flowing western boundary ocean currents can hold speeds of up to 2.5 m/s which could supply a beginning of comparatively high power denseness for power coevals although there are no commercial undertakings presently under development. Eskom is actively involved in research on this topic.18 Energy denseness of H2OBecause the energy denseness of a medium is straight relative to its denseness and is a map of the speed cubed, the energy denseness for H2O is far higher compared to weave at comparable speeds. The denseness of H2O is about two orders of magnitude higher than that of air. This means that an ocean current is far more fecund as a resource compared to onshore air current. Due to the rough environment demands on an ocean current generator, it is assumed that for a commercially feasible undertaking, the energy denseness should be dual of that required of air current. This implies that currents with speeds of at least 1,5 m/s need to be found.19 Solar e nergySouthern Africa has over many old ages used the copiousness of sunlight to market the state as â€Å" Sunny South Africa † . It is hence non surprising that this signifier of energy is regarded by some as the chief beginning that can significantly act upon Eskom ‘s supply side.20 Solar panelsThe work about solar panels both photovoltaic and solar H2O warmers are good known and late Prof Vivian Alberts of the University of Johannesburg announced a discovery in the production of a new photovoltaic panel that will be up to 50 % cheaper than anything else on the market ( Venter, 2007 ) .21 Concentrated Solar Power ( CSP )Another exciting and advanced usage of solar power is presently being investigated by Eskom. The engineering referred to as concentrated Solar Power ( CSP ) uses sun energy to heat a mixture of 60 % Sodium Nitrate ( NaNo3 ) and 40 % Potassium Nitrate ( KNO3 ) to a temperature of 565A °C. CSP is besides regarded as the lone large-scale renewable engin eering with proved energy storage. The heat energy can be stored for up to 14 hours and is used to bring forth steam for the 100 MW reheat steam turbine at a unrecorded steam force per unit area of 125 saloon. This means that the works will be able to bring forth power for a full 24 hours during the summer solstice. An mean expected burden factor of 70 % is expected.22 DecisionAs the demand for electricity rises, a more sustainable energy beginning to replace the dodo fuel energy beginning was investigated. In South Africa research has been done in both the engineering and tackling electricity from renewable energy beginnings. The study showed that hydro energy, weave energy, ocean current energy and solar energy were investigated. Due to the changeless sunlight in South Africa, it appeared like solar energy would be the most dependable energy beginning.

Revision Essential Strategies and Techniques

Revision Essential Strategies and Techniques Excellent Tips on Revision Almost everyone knows how important revision is. The majority of students are very diligent about it, but it does not always work out as planned. As is the case with every aspect of ones endeavors at study, it is important to plan revision time in advance and make sure the time available is well-organized. Revision serves the following purposes:To ensure you understand the subject matter or topic you are being examined on To ensure everything you have learnt is committed to memory To get some practice in developing study plans and answering exam questions.In order to do this, you need to put your notes in order e.g. any essay notes, class handouts, and so on. These should be arranged into cohesive and convenient sets. This article offers tips on:creating revision plans ensuring revision is productive effective techniques continual revision, e.g., throughout every term and continuously during the year.Creating Revision Plans As with many things, the key to success is good planning. Here is some useful advice:Draft a timetable for revision activities It is best to begin revising well before exams start 5 or 6 weeks beforehand at least. Set realistic goals according to the time available to you and do not forget to include periodic breaks. Look at revision tasks and balancethem Divide your topics up and allocate them to particular days, making sure there is plenty time for all revision tasks. Look at the available time and balance it out between your different subjects and/or courses. Try not to be neglectful about subjects you find especially difficult or easy. Identify all main subjects or topics Work out which subjects or topics need revising for every course. As an absolute minimum, you should aim to cover double the number of topics, as there are questions to be answered e.g. eight topics for a four-question exam. Topics should be chosen according to: A particular courses content Your particular abilities and areas of interest Previous test papers Organize all revision materials Most students collect a myriad of notes from lectures, seminars and classes as well as from textbooks and academic journals. Additionally, you may have reference materials, handouts and photocopied texts to go back over. On top of all this, you will need past test papers, course books, and so on. All these materials should be well organized in good time.Making Sure Revision is Productive Techniques The three main methods of revision are:Taking and/or making notes Committing to memory Writing model or practice answers.The next section looks at each of these methods separately: Taking or Making Notes Please refer to the Taking/Making Notes section on our writing services website for more in-depth information on this activity. During each academic term and indeed throughout the entire year, students usually take a lot of notes from various lectures, classes, seminars, and reading materials. Now that it is time for revision, your primary goal is to find the best ways to memorize these notes:Physically arrange all notes in a logical, clear and sensible way so that you can easily navigate your way through them. Next, read through all your notes, highlight key words and phrases, and mark out important themes. Make up a color code system whereby you allocate specific colors to particular themes or topics. Color association is a good way for memorizing material and compartmentalizing it in the mind. Rewrite your notes in more concise form, narrowing the content down into portions that are easier to manage and digest. Your goal should be to condense each set of topic notes so that they fit on an index-size card. This transforms notes into a memory aid rather than several pages of information, arguments, facts, and figures. Mind mapping, concept maps, and spider diagrams are useful ways of condensing a myriad of information onto one page. They are also a good aid to visual memory.Remember that less is a lot more where note taking is concerned, at least for the purpose of revision! Committing Material to Memory This is a task that cannot be avoided if you are to do well in your exams. You simply have to be able to remember your course material. Therefore, you need to find an effective way to do this. You may find the following techniques helpful:Look three or maybe four times at your different topic notes. This should help fix them in your memory more so than a one-off approach. Envision certain notes in your minds eye before looking at them. Then, while you are reading, any forgotten material will come to the fore. Another good memorization aid is theCornell approach. With this note-taking system, you simply cover half a page of detailed notes and try to recall the material from key words, phrases, and questions. The mnemonics approach is another method you might want to consider. Here, you take the initials or certain letters from a word or phrase to create memory associations. For instance, if your topic is Shakespeares Most Famous Comedies, you could use the word TALL to memorize some of the names of the great writers works e.g.: T= The Merchant of Venice A= As You Like It L= Loves Labors Lost L= Loves Labors Won Get a mental picture of your subject or topic. Continuing with the example above, you could form a minds eye picture of a Shakespearean character or play you have seen to make associations. Mind mapping, concept mapping, spider diagrams and similar techniques are good for initiating visual stimulation so that points and lists can be remembered more easily. With notes condensed to a compact level, it is usually helpful to look over these at the last minute. However, please note that trying to learn new exam material immediately before an exam is not very helpful because it can cause existing knowledge to be replaced and it can cause the learner to panic and become confused.Writing Model or Practice Answers A key element of revising is writing model or practice answers to expected exam questions. This method helps you memorize materials, improves your critical thinking skills, and provides exam practice. Check out the Essay Writing section of our website and try to condense the process we describe into abbreviated form. You could use the following steps as practice:Undertake an analysis of previous exam questions Look at the way questions are worded in previous examination papers. Can you see the problem, task and/or keywords? Can you tell which approach is required? To work out the precise meaning, try rephrasing the task or question in your own choice of words. Come up with ideas The majority of exam questions require five or six main arguments or points (at least) in their answers. Most times these should be obvious from your reading materials and notes. Otherwise, consider the what, who, when, where and why questions to generate ideas. Noted authors and controversial opinions What is the most prevalent thinking on a particular topic? Does this thinking share any important similarities or developments? Your essay will be much improved if you can briefly sum these up, particularly if they help you figure out your own position. Look at the problem from every angle There are topics that should or can only be viewed from one angle. However, your essay should be better quality and you should get the attention of your examiners if you consider your topic from other perspectives, where appropriate or relevant. Double-check your work Once your draft answers are ready, go back over them checking for mistakes, irrelevancies, and ways to make arguments stronger. Try writing in an exam environment For practice purposes, try writing at the same speed you would in an exam situation. If possible, ask for other peoples opinions on your answers. Your course tutor or friends may be happy to look over your work. Revise Throughout the Entire Year Do not make revision an attempt at the last minute to compensate for previous neglect. It is extremely easy to forget earlier work when topics succeed each other at a rapid pace. It can seem there is little or no time for revision, but you should keep an eye on upcoming exams throughout the entire college year. Write notes so that they are well organized, easy to read, and comprehensible. File and label everything neatly. Maintain reading lists and reference lists. Keep a stock of previous exam papers and questions. Make a note of any outstanding tasks and/or investigative work. Avoid letting work build up. Even when you put time aside for catching up, it might not be possible to get the reading materials you need close to an exam. Read back over your notes from time to time. Use them to get a view of your course as it is at any given point. Create links between what has already been taught and what is still outstanding. End-of-course lectures are a good way of getting last-minute tips and advice.If you find any particular element of your course especially confusing, take time to review textbooks, previous exam papers, and notes. Look at your course in its entirety and try to put everything into perspective. Talking to your tutors and attending introductory courses and lectures can also help.

UK Position Paper Free Trade

UK Position Paper Free Trade UK Position Paper Free Trade Committee: Global Economics Topic: Free Trade Country: United Kingdom Free trade is when one country lowers, or removes, their trade tariffs and gives subsidies on exports and imports to other countries. Free trade is supposed to be a tool used by countries to obtain resources that are scarce in their country while making the most of the local resources that are available. Instead, large corporations in developed countries who mass produce goods use the free trade agreements of lower tariffs and subsidies to sell their goods in third world countries, which hurts local businesses. This results in an unequal distribution of wealth because the developed nations will exercise a protectionist policy when it come to agricultural trade, which happens to be third countries’ biggest export. These protectionist policies make it hard for third world nations to compete equally in the global market, and thus occurs the conflict of viewpoints on free trade. The first cause of this problem is the fact that third world countries strongly believe in the protectionist view on trade. This is because smaller third world nations know that the only way their domestic economy can grow is by limiting, or eliminating, foreign competition. By radically increasing the tariffs for imports in their country, this will decrease the international competition faced by local manufacturers, and will allow the the local economies to grow, thus increasing the country’s GDP and strengthening their economy. These countries are aware that with no tariffs large multinational corporations can come in and monopolize the market of their choosing, and that small local businesses are the only way their economy can grow. Developed nations also have caused problems with free trade by overemphasizing its importance. They often times blame the fact that third nations have not lowered their tariffs, and this is why their economy is so stagnant. But when third world countries open up their trading boundaries, large countries like the USA take advantage of these low tariffs. A 2002 study showed that the US exported wheat 43% below its production cost, creating tough competition for local farmers. This low export price faced from the US is what allows them to sell their goods at such a low price in the international markets, which consequently hinders the growth of local businesses and the overall economic growth of the country. The UN is in cooperation with the World Trade Organization to help moderate free trade negotiations between countries. In July 2009, the UN wanted to â€Å"resist all protectionist tendencies and rectify any protectionist measures already taken,† which shows that the UN leans towards a more free trading style between countries. They have mediated several hundred negotiations in the past such as NAFTA and other large international trade agreements. The UK strongly supports the concept of free trade as much of our economic strength depends on our trading relations with other countries. As a member of the European Union and the Transatlantic Trade and Investment Partnership the UK notes that strong economic ties with countries all over the world is the best way for an economy to grow. Countries can benefit from trade and investment with other countries while specializing in a specific good to export to other nations, thus increasing domestic production rates and strengthening the economy.

Wood vs. Wooden

Wood vs. Wooden Wood vs. Wooden Wood vs. Wooden By Maeve Maddox Some adjectives with two forms often create doubt in native speakers. Take for example these uses of the words wood and wooden: Youll want to budget about $4/square foot for a wood deck Building a wooden deck over a concrete one 68 Wooden Deck Design Ideas Expansive wood deck with low wood railing using diagonal wood floor design Which is correct? â€Å"Wood deck† or â€Å"wooden deck?† Strictly speaking, wood is a noun and wooden is an adjective, as illustrated in this headline: Wood science and how it relates to wooden baseball bats In this example, wood functions as a noun: â€Å"the science of wood†; wooden functions as an adjective: â€Å"bats made of wood.† But although this â€Å"rule† of distinguishing between noun and adjective can be applied to wood and wooden–and possibly to wool and woolen–most of the -en adjectives that describe substances have become relegated to the realm of poetic or figurative language. The following examples show how the -en adjective forms were used in their older, literal senses: ash: ashen â€Å"The city had been one mass of colorOne great crumbling mass of ashen ruins was what we found left of all this.† brass: brazen â€Å"It grew dark, and they put candles on the tablescandles set in bright, new, brazen candlesticks.† flax: flaxen â€Å"the early-modern hemp industry was far more versatile than has been supposed and was capable of producing not only ropes and canvas, but also hempen cloth some of which could rival all but the finest flaxen cloth.† gold: golden â€Å"Three compartments divided the coffer. In the first, blazed piles of golden coin; in the second, were ranged bars of unpolished gold.† lead: leaden â€Å"The water was formerly conveyed by wooden pipes from these basins through all the streets, and a leaden pipe, inserted in the main, supplied each house.† oak: oaken â€Å"Pine lids were not put on oaken chests in England at this early period.† silk: silken â€Å"From an anecdote of Aurelian, who neither used silk himself nor would allow his wife to possess a single silken garment, we learn that silk was worth its weight in gold.† wax: waxen â€Å"One of the wedding presents had been a pair of beautiful white waxen candles.† In modern usage, the noun in each of these pairs serves also as an adjective. For example, brass for brazen and flax for flaxen: these tarnished brass candlesticks looked better suited to a flea-market stall than a dining table.   It was sometimes said that the flax rope was apt to break when a knot was made in the rope. The -en forms do survive in figurative contexts. Here are just a few: She’s a brazen woman and no mistake! (impudent) â€Å"They’ve caught us trespassing; we’ll have to brazen it out. (face the situation impudently) The dead man’s face had a waxen hue. (appearance of wax) The girl had laughing blue eyes and flaxen hair. (any light shade of auburn or pale yellowish brown) Keep an eye out for other examples of these -en adjectives in modern English. Want to improve your English in five minutes a day?

Understanding Business and Management Research Methods Coursework - 1

Understanding Business and Management Research Methods - Coursework Example When choosing a model, it is critical to know the theory being applied. Studies indicate that, behind every method, there is always a theory. This paper will discuss the three business and management research methods. The paper will start with the introduction, and then literature review, then analysis and evaluation of different methodological approaches, and finally highlight the main findings. In any research, it is always recommended to choose a single paradigm (qualitative, quantitative, or mixed) for a research work (Anderson, 2009). The selection is based on the pragmatic choices which are time, skills, and overall size of the project. The research methods are based on differences in the nature of reality, relationships to that being researched, role of values, use of language, and overall process of research (Bellamy, 2012). Research methodology is what constitutes a research activity. Bowerman (2013) distinguishes the three research designs as follows Quantitative research: This design is useful for exploring and understanding the meaning behind problems. Data is collected on the participants setting, and the researcher makes interpretation of the data collected (Bowerman, 2013). Quantitative research: The researcher tests theories by examining the relationship amongst variables that can be measured on an instrument to allow numbered data to be analysed using statistical procedures (Bowerman, 2013). Mixed methods: This design combines both qualitative and quantitative forms of research. It concerns the application of qualitative and quantitative methods in tandem, to allow the strength of the study to be greater than either a qualitative and quantitative approach (Bowerman, 2013). When undertaking a business research, a combination of different types and sources of data is required to derive strong findings. The types of data are qualitative and quantitative, and the types of sources are primary and secondary sources (Harwell,

Business Research and Writing Paper Example | Topics and Well Written Essays - 3000 words

Business and Writing - Research Paper Example The purpose of this report was to evaluate the factors that must be considered before expanding the business on foreign soil. To evaluate the factors, the study focused upon taking the scenarios of other electronic organizations that geographically expanded their business without any difficulties. The thorough investigation of similar businesses led to an understanding the organizations must consider opportunities and growth prospects before expanding outside national borders. This can be clearly witnessed through the expansion of Sony. Not only did Sony focused upon the opportunities, but the company also held the confidence to succeed in the given market conditions. On the other hand, the case of Telefonica revealed that rather than focusing upon the opportunities, the Spanish company focused upon evaluating the similarities within the institutional and cultural characteristics in Latin America. Once it understood that both the countries shared similar characteristics, it expanded internationally despite the several criticisms against the geographic expansion. Lastly, the case of Mouser Electronics revealed that the evaluation of demand must be considered before expanding the business internationally. ... The products offered by the company have significantly enhanced the convenience factor of the customers, while providing the customers with additional value in their lives. To continually remain ahead of the competitors in the electronic market, Company G has always focused upon the offering of its competitors (i.e. the leading companies). This is primarily done to provide the customers with the best possible alternative in the market at comparatively lower cost than others. By assessing the tremendous demand of mobile phone and smartphone chargers in the market, Company G has introduced its own brand by the name of ‘ChargeOn’. The specialty of this charger lies within its convenience and small size. Within just half an hour, ChargeOn can charge any mobile or smartphone battery completely, while ensuring the maximization of battery life to significant level. Similarly, ChargeOn is a special charger that is water resistant. To perfectly meet the demand of the customers in the electronics market, the charger will be available in three ranges; standard USB jack, micro USB jack and mini USB jack. With outstanding opportunity to expand geographically, Company G has selected Canada for the expansion.

Psychology Literature Review on Peer Pressure and its influence on Essay

Psychology Literature Review on Peer Pressure and its influence on females appearance schemas and body dissatisfaction - Essay Example Benedikt, Wertheim, and Love (2002) and Paxton et al. (2003) found that best friends' encouragement to diet increased dieting behavior among adolescent girls. Dixon, Adair, and O'Connor (2000) also found that peer encouragement to diet (separate questions were not asked for other friends and boyfriend) was associated with both body dissatisfaction and dieting behaviors among adolescent girls. However, there was no overall association between the dieting practices of friends and those of adolescent girls, although boyfriends' dieting behavior was associated with some aspects of their girlfriends' dieting behaviors. Keel, Heatherton, Harnden, and Hornig (2001) also found that although boyfriends influenced their girlfriends' body dissatisfaction but not their eating practices, best friends had a greater influence on their girlfriends' dieting behaviors. In contrast to these findings, Steiger, Stotland, Ghadiriam, and Whitehead (2003) found no difference among binge eaters, dieters, and no dieters in the eating concerns of family members. The authors suggested that rather than an actual eating disturbance, it may be a general tendency toward some form of psychopathology that is associated with eating disturbance among adolescent girls. A follow-up study by Steiger, Stotland, Trottier, and Ghadiriam (2000) indicated that there was some association between girlfriends' and best friends' eating concerns, but that the strongest influence on disordered eating among adolescent girls was psychopathological traits of friends. Other researchers have also reported that friends of eating-disordered adolescents did not differ from control-group friends on dietary restraint or eating disturbances (Evans & le Grange, 2003; Leon, Fulkerson, Perry, & Dube, 2003), although some studies have revealed a relationship between best friends' eating restra int and that of their girlfriends but not of their sons (Ruther & Richman, 2003; Scourfield, 2003; Thelen & Cormier, 2003). The results from the aforementioned studies demonstrate a lack of clarity in the extent to which best friends and boyfriends may influence body satisfaction and disturbed eating among adolescent females and girls, with a particular focus on girls. Furthermore, that research has focused on weight loss but neglected consideration of strategies to gain weight and increase muscle tone. These are strategies that may be particularly relevant to adolescent females, but the impact of peer feedback on these strategies has not been explored. It is important to determine the nature of the feedback provided to adolescent females, how it differs from that provided to adolescent girls, and the impact of this feedback on weight gain and strategies to increase muscle, as well as weight loss. Peers also seem to exert some pressure among
