The Finite Element - Research Paper Example One of the main challenges in solving partial differential equations is to use equations which are approximate but numerically stable so that error accumulation does not cause the solution to be meaningless. The finite element method is an excellent technique for solving partial differential equations over complex domains. Application of the finite element method in structural mechanics is based on an energy principle, such as the virtual work principle, which provides a general, intuitive and physical basis. The finite element method originated as a technique used to solve stress analysis problems, but today it can be applied to a multitude of disciplines ranging from fluid mechanics, to heat transfer to electromagnetism. The buckle of a standard lap belt used in passenger aircrafts has been designed and is ready to undergo testing. In order to be released into the market, the strap system must be able to withstand a 450 kg tensile load. It is assumed that the weakest point of the design is the flat plate of the buckle. Thus, prior to engaging in a costly test scenario, a simple finite element analysis of the buckle is to be made to insure soundness of design, i.e. the material does not exceed its yield strength and no significant distortion occurs. Preparing the problem for analysis first requires definition of assumptions. Figure 1 is a schematic drawing of the buckle to be analy... thickness of the part (which is assumed to be constant) is believed to be small enough compared to the width of the part such that shell elements can be used. Displacements are expected to be relatively small such that a linear approximation will be valid. Figure 1 2.2 Material Properties The part is manufactured from 2.5 mm stainless steel plate with a Young's modulus of elasticity of 206 GN/m2, Poison's ratio of 0.3, and a yield strength of 580 MN/m2. Homogeneous and isotropic material was assumed with no discontinuities or residual stresses present as a result of manufacturing processes such as forging, rolling and welding. The material is assumed to have linear elastic properties. 2.3 Mesh A mesh that provides a good representation of the model is critical for an accurate solution; the elements must be well-shaped and close fit. For this analysis, the element type chosen was PLANE82, which is a 2D structural solid element. The element has 8 nodes, which increases calculation time over its 4-node counterpart but also increase accuracy of solution. Eight-noded elements are also known to be more accurate for modelling curved boundaries, which is where the areas of maximum stress were expected in the buckle. The PLANE 82 element type also offered the benefit of accounting for a thickness value in its input properties. Since maximum stress values were expected in the curved sections of the part, two meshing values were utilised, thus providing a denser mesh in critical areas. In the curved areas, a value of 0.25 was used, while 0.51 was used in the rest of the model. 2.4 Boundary Conditions Determination and application of boundary conditions is critical to the analysis. For this model, it was assumed that displacements would be small enough so as to not

Sosial anthropology - Essay Example Led by Wired, dot com boosters were claiming that the Net was creating the free market only found up to then in the neo classical economics text books. Inspired by post modernist gurus, new media activists were convinced that humanity would liberate itself from corporate control by escaping into cyber space (Barbrook, 2005) Jumping forward from the 1990s to the year 2008 the above quote seems true to both sides. On one hand we have seen a huge shift in the way that people consume with more and more people choosing to sell and buy over the world wide web, vast amounts of profits generated for companies like Google who enjoyed in the â€Å"1990s an estimated growth of 100% per year.† (Coffman, K. G; Odlyzko, A. M. 1998) The internet market has continued to grow substantially year on year as technologies change and more and more parts of the world come on line. On the other hand, an extraordinary phenomena is taking place throughout the world which is almost totally contradictory to the doctrine of the free market and capitalism, and that is the culture of exchange and gift economy that is developing and becoming more possible through the use of the internet and social software. A gift economy can be defined as a means in which goods and services are exchanged without there being an agreement of a reciprocal return to the giver. Most anthropological academics, however would agree, although there is no implicit need for a return gift there is often an expectation of reciprocity. Marcel Mauss in his classic work "The Gift1" argues that gifts are never free and that the act of giving creates a social bond that requires obligation to reciprocate on part of the recipient. This reciprocity however is not however solely between two people but between group, tribes and communities. Further studies challenge the idea that reciprocity is an inevitable outcome of exchange and focus on the classification of different types of reciprocity. For the purpose of

The Impact of Anarchy Essay Example for Free

The Impact of Anarchy Essay Anarchy is found in all societies to some certain degree.   The sound of such may not seem to be as delightful as that of â€Å"governmental† successes in account, but digging deeper on such, shall open a whole wide range of arguments brought by anarchy in the field of history (Black, 1980). As a philosophical term, the definition of anarchy is most likely described as an opposing origin of arche which does not mean opposing the political leader.   It significantly comes to mean the principles of element, supreme power, sovereignty, dominion, command, authority then leading on to an empire, a realm, magistracy, a governmental office, at that (Weir, 1997). The exact meaning of the word which is normally being collaborated with the word â€Å"opposing† had then evolved through time that it has continuously occupied improper and confusing usage.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Men of culture always tend to have something in common.   The transformation of society had been blatantly felt during the French Revolution that the European society is remade using a new set of political models and thus having the modern-nation states start to emerge, so as with national cultures (Weir, 1997).   Supposedly, not on a plurality but totality scheme, culture was not to be divisible but such counter-movements during that era floated up in the scene.  Ã‚   For the reason of such scenario, it is precisely fit to assume that politics is intrinsically anarchic given the fact that it has the potential to separate and divide populations along ideological lines.   Moreover, democratic politics is also considered as the most divisive force of all, having the tendency to produce individuals wherein such primary culture may be compensated in allegiance to them (Lilly, Cullen, Ball, 2006). The unfortunate factors of such circumstance are the losses it takes under the cohesion of the culture.   On the other hand, the social disintegration on culture caused by wrought of politics may lead to weaving disparate individuals together again, forming an alliance of which adheres with a common thought that they have (Weir, 1997).   In a form of integration for a common sensibility the affirmation of anarchism being practiced by such considered politicians and thus perceived as a threat of social disorder is countered in the scheme of culture by all right and even culture itself is as a matter of fact no longer the universalizing force outside of history humankind suppose it to be (Rueschemeyer, 1978).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The behavior of law constituting all the massive forces of political power, by all means also convey the act of anarchism.   Considerably, the classical illustration of Donald Black with regards to such also gave a couple of relevance in displaying the classic formulation of laws. Its comprehensive explanatory theory of the law revolved around governmental social control, margin of stratification, proofs of differentiation, social distance specifications, and periphery of social life location, culture symbols, organizational management techniques and non-legal social control incidences (Black, 1980).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The variation of all fields of law had been divulged on to the role and the impact made by anarchy. He announces the major phenomena of anarchy as one which are treated as variables in the quantitative state.   Significantly noting such as to a social life without law, hence, that the earlier societies were measured in banishment, beating to ridicule and even teasing. He even cited the point of dictatorship as one which tends to surrender their usual liberties for the strength of the organization (Lilly et al., 2006). All of which he tantamount its capacity and capability to explain other kinds of social control on how it is specifies the conditions of anarchy-social life without law by implication basis.   Theories ought to lay a couple of explanations so as to know how a phenomenon had shrugged a state, or a government (Weir, 1997). In conclusion, the impacts of anarchy defy explanatory implications which orbit around culture and society and now pave a forceful supremacy in the cloud of politics in historical precessions.

Green Banking: An Evaluation on Rupali Bank Limited

Green Banking: An Evaluation on Rupali Bank Limited Green Banking- Way to Sustainable Development: An Evaluation on Rupali Bank Limited Introduction Background of the study Green banking is a process of promoting environment friendly practices by different banking activities. Bangladesh is a most climate change vulnerable country in the world and green banking is a tool for acquiring reputation. Green bankers are concerned about sustainable development and it is a special agenda to take care of environment of the earth. Green banking is a proactive and effective step with a vision for future sustainability. Green banking activities are sustainable banking, ethical banking, green money market account, mobile banking, waste management, remote deposit and green financing. Green banking focuses on green transformation of internal operations of all banks. Bangladesh falls into the group of most climate change countries in the world comparison with other developing and developed countries. Bangladesh Bank issued green banking policy guideline in February 2011 to conduct environment friendly banking activities in the country. According to these guidelines, all financial institutions and banks need to take effective measures to conduct environment friendly banking activities in Bangladesh. Bangladesh Bank issued a common reporting format to all commercial banks to report green banking activities in a structured way. Banks and other financial institutions have to submit a quarterly report to Bangladesh Bank on their performance of green banking activities. According to green banking policy of Bangladesh bank, banks have to determine vision, mission and strategic planning covering in house green banking activities like follow green architecture, use energy saving technologies, reduce dependency on grid power and green financing practices l ike providing green loan to promote solar energy, bio gas plants, develop green banking products for clients, increase online and mobile banking etc. Rupali Bank Limited performs several green banking activities like in house environment management, green financing like installation of EFT, Bio gas plant, establishment of solar panel etc. Rupali Bank Limited also involves in green marketing activities to ensure environment friendly activities like plant tree, finance in environment friendly projects, pay bill via online, be paperless etc. Objectives of the study There have been some objectives set forward in doing this report.

An Evaluation What Is Game Based Learning? An Evaluation Many people believe that gaming is addictive and can lead to violence, a belief that is not substantiated by research. Researchers have shown that the source of behavioral problems of young people who play video games comes from elsewhere. One study found that people who play video games spend just as much time reading, doing homework or participating in other social activities as people who do not play games at all. This raises the question: can video games be used for learning in the classroom and would they have positive results? When education starts to feel dull, we are not being engaged or motivated, which means we are not really learning. According to Foreman we can look at the lecture as an example. With all the technology being thrown at young people today, they are going to say, why am I sitting in this lecture listening to this person? Learning is just not memorization; it means the act or process of acquiring knowledge or skill. Students do not need to spend more time in the classroom to learn how to think and perform. They need effective, engaging experiences that can motivate them in the learning process. Educational games can be a powerful tool for teaching and learning. These games are used to reinforce learning, they offer immediate feedback, recurring gratification and prolong the interest of learners. Why it works Game-based learning is a simple concept, where games are used as a learning tool to engage students. In Jane McGonigals book, a game is defined as an activity that has goals, rules, a feedback system, and voluntary participation (pg 100). Some pedagogical considerations that are derived from game based learning are that content and/or skills can enhance learning vs. traditional methods; Students can build their own games in order to learn and develop skills; They can use game mechanics in the learning environment, for example using levels instead of grades, coined gamification of the learning process. In 2003 author, James Paul Gee wrote the book, and in it he described the impact of cognitive development with game play. Gee developed 36 different learning principles that games being used in education should have. From these principles we can look at game based learning from two perspectives. The first is learning effectiveness. The second is engagement. When considering learning effectiveness, we can consider whether the game provides meaningful learning activity or whether the game is just a fun activity and does not necessarily lead to learning. We can look at what the learning outcomes are including memorization, knowledge, understanding, synthesis and creativity. For all these various learning outcomes, games can provide an enriched learning experience. The second perspective, the elements of engagement from Games Based Learning (GBL); we can ask does the game enhance learner motivation, does the game provide a fun learning experience? Is it interesting or is it a very tedious, boring learning experience? Does it add to learner concentration? Does it get the learners full attention? And finally learning by doing, games can provide an experience where the learner has to intensely engage in various activities. Where is it going? Over the last decade, research and interest in GBL has increased, as has the diversity of games themselves. Serious games and computer simulations offer an interesting context for learning because they both reinforce student motivation. Researchers found that students playing serious games or who participated in computer simulations were a lot more active as they manipulated objects. Students also had control over their actions and were more engaged in their learning. Researchers found that animation in the games increased motivation, and that students were more likely to return to activities that included animated graphics. They also found that serious games support inductive, experiential learning, with a genuine constructivism approach. Online gaming provides a context for adaptive learning, because they allow for multiple personalized paths or itineraries. Communication among players also introduces a social aspect that opens doors to knowledge acquisition with peers. Challenged- based and collaborative games are an emerging category of games that seem particularly appropriate for higher education. These games allow students to use skills for research, collaboration, problem solving, writing, leadership, digital literacy and many more. They are open-ended and occur in both online and non-digital forms. Games will undoubtedly evolve in the future and therefore GBL will also need to evolve, we are seeing new types of gaming, such as alternate reality games, social/mobile games, we are also seeing innovative new ways to use GBL. Conclusion Game-based learning has gained more traction in recent years and is becoming more accessible with many benefits. Game-based learning can make learning more situated, contextualized and personalized. GBL can be used for learning content and skills, including 21st century skills like innovative problem solving and collaboration. GBL can even be used for practicing and honing existing skills. Game based-learning engages students, and if students are engaged they will embrace learning rather than view it as a tedious boring learning experience. AC Voltammetry: Principles, Advantages and Disadvantages AC Voltammetry: Principles, Advantages and Disadvantages Name TEH YU JIE (K) NOOR HASIRA BINTI SAMSUDIN NUR NADIAH BINTI ABU BAKAR NUR NIQMAH BINTI MUSA NUR SYAHIRAH BINTI KHAIRUDDIN KHANG EE WEN INTRODUCTION Nobel Prize winning chemist Jaroslav Heyrovskà ½ facilitated voltammetry by the discovery of polarography by in the year of 1922. Alternative current voltammetry was invented in 1950s and developed intensively by D.E Smith. Alternative current (AC) voltammetry is an accurate electroanalysis method and combination with preconcentration will enhance the sensitivities of this analytical techniques. AC Voltammetry generally involves in the application of a sinusodially oscillating voltage to an electrochemical cell. The AC experiment is used in conjunction with a fixed amplifier or frequency analyser which will increase sensitivity considerably over the early described techniques. AC voltammetry can also reveal the important of mechanistic and kinetic information which is not easily available when using the tradition voltammetric techniques. Measurement of AC voltammetric is usually used in an electrochemical cell and the dominate mode of transport is diffusion. A steady DC signal or voltage sweep will often combined with the AC voltage. The following figure shows a cyclic voltammetric signal with an AC perturbation. Alternating potential usually has a frequency of 50-100Hz and 10-20mV amplitude. The AC signal causes a perturbation in the surface concentration and DC potential ramp maintained the concentration. The resulting AC current is plotted against the potential. For example, voltammogram appears a peak, the potential of which is the same as the polarographic half-wave potential. At this region, the sinusoid has maximum impact on the surface concentration like on the current. For a reversible system, such a response is actually the derivative of the DC polarographic response. The concentration of the analyte is proportional to the height of the AC voltammetric peak and for a reversible reaction to the square root of the frequency (ω), the term is the amplitude. WORKING PRINCIPLE AC Voltammetry typically involves the application of a sinusodially oscillating voltage to a electrochemical cell. When used in conjuction in the ac experiment with a lock in amplifier or frequency analyser. It offers a considerably increased sensitivity compared to the early described techniques. It can also reveal necessary mechanistic and kinetic information that are not easily available by using some other tradition voltammetric techniques.Usually, diffusion is perfomed as it was the dominate mode of transport. The AC voltage is often combined with either a steady DC signal or voltage sweep. There are three component steps involved in an electrochemical process, mass transport,chemical and adsorption steps and electron transfer. They all are actually contribute to the total potential drop across the cell. If an AC current flows, it will be necessary to distinguish purely ohmic resistance from non-ohmic,complex and normally frequency dependent resistance(often term impedance).Besides,treatment of the AC response of electrochemical cells will follow the pathway with initially a general treatment. The treatment of the two simpler cases of purely diffusion controlled and purely electrochemically controlled reactions will be conducted. Under AC measurements,there are 5 methods: Influence of transport processes on the ac impedances of an electrochemical cell. Equivalent circuit for an electrode-diffusion-limited reaction.(the circuit elements describing the flow of ac current through an electrode comprises an electron transfer resistance,Rà ¡Ã‚ ´Ã¢â‚¬ ¦ and Warburg impedance,Zà ¡Ã‚ ´Ã‚ ¡ in series. AC impedance of an electrode where the electron transfer process is rate limiting. Logarithmic or bode plot representations. Electrode reactions under mixed control Alternating current bridges use the principle of balance between the variable impendance, ZS and an electrochemical cell under study. An electrode process normally consists of a resistance RS in series with a capacitance CS. The resistance includes the resistive components of the electrode process of the solution and the capacitance is due to the working electrode. A combination of capacitance and resistance has been used in parallel. The analysis is more carried out in these conditions in terms of admittance Y=1/Z Potentiostat is more convenient to use when it is important to apply a d.c potential to the cell in addition to the a.c perturbation. Potentiostat is simultaneously applies the d.c potential and the detection rather than conventional detector. It is good stability in the applied potential and accuracy for wide range of frequencies while the electronic component of the potentiostat is only limited by these characteristics. This arrangement is known as a potentiostatic bridge. The accuracy of bridges at high frequencies are depends on cell design. This is due to the ions are moving faster than the time needed for rearrangement of the ionic atmosphere and occur above 10 MHZ . The technique is actually very similar to the normal frequencies but it was also time consuming. This technique also has a disadvantage such as the impendance of the whole cell is measured. In the investigation of electrode process the disadvantage when one is interested in the properties of one of electrode. By using an auxiliary electrode with an area large relative to that electrode, it is possible to reduce the contribution of the unwanted components. ADVANTAGES AND DISADVANTAGES AC Voltammetry is one of the techniques based on the analysis of faradaic impedance. A low-amplitude sinusoidal voltage is given to the working electrode, which is also established at some DC voltage with regard to the reference electrode. Because of the difference in the time scale, the AC component of the total current can be readily differentiated from the DC component. The kinetic parameters can be carried out either from the amplitude of each current or from the phase angle between the AC current and AC voltage (C.G Zoski, 2007). The significant advantage of AC Voltammetry is that it allows relatively easy evaluation of the solution resistance and double layer capacity. Without simplifying assumptions the analysis of faradaic impedance even for a simple response is quite complicated. The commonly used assumption is that the DC and as components of the total current can be uncoupled is reasonable because AC Voltammetry is typically applied to measure fast electrode kinetics. The other advantage of voltammetry as quantitative method of analysis is its capability for analyzing two or more analytes in a single sample. As long as the components behave independently, the resulting voltammetry for a multi component mixture is a summation of their respective individual voltammograms. Voltammetry has been used for the quantitative analysis of a wide variety of samples, including environmental samples, clinical samples, pharmaceutical formulations, steels, gasoline, and oil. Some advantages and disadvantages are specified in the form of accuracy, precision, sensitivity and selectivity. The accuracy of a voltammetric analysis usually is limited by ability to correct for residual currents, particularly those due to charging. For an analyte at the parts-per-million level, an accuracy of  ±1–3% is routine. Accuracy decreases when analysing samples with significantly smaller concentrations of analyte. Precision is generally limited by the uncertainty in measuring the limiting current or the peak current. Under most conditions, a precision of  ±1–3% is reasonable. One exception is the analysis of ultratrace analytes in complex matrices by stripping Voltammetry, in which the precision may be as poor as  ±25%. In many voltammetric experiments, we can improve the sensitivity by adjusting the experimental conditions. For example, in stripping voltammetry we can improve sensitivity by increasing the deposition time, by increasing the rate of the linear potential scan, or by using a differential-pulse technique. One reason that potential pulse techniques are popular is that they provide an improvement in current relative to a linear potential scan. Lastly, selectivity in voltammetry is determined by the difference between half-wave potentials or peak potentials, with a minimum difference of  ±0.2–0.3 V for a linear potential scan and  ±0.04–0.05 V for differential pulse voltammetry. We often can improve the selectivity by adjusting solution conditions. The addition of a complexion legend, for example, can substantially shift the potential where a species are oxidized or reduced to a potential where it no longer interferes with the determination of an analyte. Other solution parameters, such as pH, also can be used to improve selectivity ( D.Harvey,2000). COMPARISON OF AC VOLTAMMETRY WITH OTHER TYPES OF VOLTAMMETRY Voltammetry is a category for electro analytical method mostly used in analytical chemistry and various industry processes. Consist a lot of example of voltammetry that been used such linear sweep voltammetry, staircase voltammetry, square wave voltammetry. Others example like cyclic voltammetry consist of method that can be used to determine diffusion coefficient and half-cell reduction potentials. Anodic stripping voltammetry are also the example of voltammetry that are quantitative analytical method for trace analysis of metal cations. Then, cathodic stripping voltammetry are also as example of this voltammetry that are quantitative analytical method for trace analysis of anions. Other than that, adsorptive stripping voltammetry is a quantitative and analytical method for trace analysis. Alternating current voltammetry and polarography in example of voltammetry that polarography is a subclass of voltammetry where the working electrode is a dropping mercury electrode that useful for its wide cathodic range. Lastly, rotated electrode voltammetry is a hydrodynamic technique in which the working electrode. This technique is useful for studying the kinetics and electrochemical reaction mechanism for a half reaction. Then, the normal pulse voltammetry, differential pulse voltammetry and chronoamperometry. RESEARCH IN AC VOLTAMMETRY Ac voltammetry is a method that seldom used on the determination of elemental elements. In general principle, the determinations are usually done is a more conventional way, that is by connecting two electron reversible electrochemical process. During the process, the mercury is oxidized to form mercury (II) ions and the electrode surface will formed at the electrode surface. In this research, we will be analyzing elemental sulfur with AC voltammetry. Generally speaking, the elemental sulfur will undergo the chemical pretreatment. For example, the process with solvent such as ethanol and toluene-methanol or methanol-pyridine. The process involved mostly organic solvent. Why the process is carried out with pretreatment but not direct determination? This is because the aqueous solutions mostly contain too less elemental sulfur to be determined. To overcome the problem, some scientist suggest that using acidification of sample to pH 5 and then with electrochemical treatment. The method itself has a higher detection rates compared to the previous one, but actually still too low for economical values.According to Batuna (1992), they try to determine the elemental sulfur by using direct determination method. And the source is natural water. The researchers are conducting the research using phase sensitive ac voltammetry because the instrument is easier to be found in the laboratory in the author’s lab. The research continues with using a PAR Model 303A static mercury drop electrode from EG G Princeton Applied Research. It was connected to a BAS-100A electrochemical analyser from Bioanalytical System that located in the West Lafayatte. They used a reference electrode of Ag/AgCl and an auxillary electrode of platinum. The instrument takes the measurement at 80 Hz and a modulation scan rate of 1 mV s-1. The temperature of the conditions was at room temperature. The solutions were deaerated for 15 minutes by using nitrogen gas and then doubly distilled and filtered with the Milli-Q filter. All measurement was actually made at the pH 10 to prevent the formation of volatile H2S. The stock solution was prepared from using the reaction between elemental sulfur and toluene. The solutions have to be prepared just before the measurements were made. This is because to prevent contamination and more complete reaction can be conducted. PAR Model 303A static mercury drop electrode RESULTS The determination of sulphide in aqueous solution are based on the insoluble mercury (II) sulphide during the accumulation period at potential more positive than ca- 0.58V. Hg + S2- à ¯Ã†â€™Ã‚   HgS + 2e A and B were showing the typical ac voltammogram of sulphide in 0.5 moldm-3 NaCl-NaOH. C is a negative going scans of 110-6 moldm-3 after 0-300s accumulation at a potential 0.5V. D shows that positive going scans of 110-4 moldm-3 sulphide after 0-120s accumulation at a potential at 0.8 V. The difference between the peaks obtained using negative- and positive-going scan directions are more favor to the negative direction. It is also important to note that there is actually no effect of accumulation under conditions on the peak height obtained with a positive-gong scan . This agrees well with the explanation that during the positive-going scan, the anodlc dissolution of mercury occurs, which is proportional to the adsorbed sulphlde on the mercury electrode.

The relationship between values and culture, leaders and teams of employees must maintain a healthy balance in order for the status quo of everyday operations to remain but also for the strategies to remain in place and augmenting in flux with market variables. This paper presents an interesting scenario of five tasks for you as the management trainee to explore and devise a financial report based on the company’s financial statements such as Profit and Loss, Year End results and other balance sheets. There is a new sales manager, who has promoted new policies toward change to increase sales and production but in other words created growing pains toward an organisation that will require investment, acquiring equipment and employees. It is part of your job to remain focused and subjective to the task at hand and evaluate each of the five tasks with the future of the organisation in mind but also the validity of such growth and the future investments needed. While outside investment is warranted at times, with a growing successful venture, it is assumed that some capital can come from within. However it is curious if her â€Å"tried and true† scheme will work for the present economic state. So many consumers purchase ticket item s on instalment credit but will this happen when consumer confidence is down and what will this mean for the organisation? TASK ONE: Effect of Policies on Company Performance There is concern that the company cannot keep up with production for this new promotion scheme set into place by the new sales manager who has promoted credit related sales. The director is concerned and has asked you to compile a report elaborating on whether the performance of the company and it’s financial position at the year-end has improved because of the new policies put into place. What is your opinion and rationale? According to the end year statements, operation costs are down which means the factory has reached a new level of efficiency. This indicates that something is going right at the shop room floor when compared with the prior year. It can be expected that the future productivity will be even higher with that rate of growth and profitability in consideration. However part of the scheme has been to introduce a line of credit to the consumer as a way of purchasing high ticket items and furnishing their homes. The main concern here when looking at the year-end statements comparatively should be cause of alarm on the point of the director. The prior year 2002 there were 166 debt accounts to the company. This year 2003 there are 1166 debt accounts and this is at a growth rate of a thousand new accounts or a rate 14 percent for this segment. The main concern here is the rate of repayment that needs to be established over time with these debtors. How quickly are they paying off their accounts a nd at what rate of interest? This could become a problem should some of them fall behind because then the company needs to implement a debt collection service, which will be an additional expense to the company. Sometimes it is impossible to collect on such merchandise. While the promotion may have spawned a tremendous amount of growth, it has also opened up the company for increased risk in the future for profit and loss. The year 2003 was a good one but one must also consider should the present promotion continue for 204, what are the long-term benefits and risks to having extended credit lines to consumers? TASK TWO: Effect of Product Diversification and Promotions Pricing strategies usually change as the product passes through its life cycle. There are a number of different methods of determining price depending on the product. In today’s game, diversification of products and product add-ons is the key to success especially in a saturated market like furniture. There is much competition. It is with this in mind that companies usually develop multiple promotions as opposed to just one. This way, the company has a promotion that can be priced for every budget. For your organisation, this may mean running ad campaigns, for instance a two for the price one during the winter season or provide extra perks for the customer who buys package deal. Right now free delivery seems to be a front runner of what the consumer is concerned about when shopping for furniture. As well as the credit offer, which may not drive many to purchase right away, have a sweepstakes drawing or a movie night that features your most comfortable display model. In a satur ated market, it is important for the prices to remain competitive, even reduced at certain times of year. By employing another marketing scheme, it is quite possible that you may see a reduction in credit accounts and more people spending cash especially if the price is right. Still one must be careful to get a return on the product as a profit because also one must consider the cost of acquiring the product, keeping it in stock and delivering to the customer. It is important to always keep in mind the cost of keeping the unit per unit in inventory. This goes beyond what it just costs to produce the unit. Still with the introduction of a counter promotion with reduced price, you will see more inventories out of the warehouse and less debtor credit involved in the transactions. TASK THREE: Risk Analysis The manager has asked you to assess the validity of two projects that are independent of each other and require proper recommendation. You will need to run a risk analysis as well as a net present value analysis in order to determine which project to recommend as both will reduce the handling cost and warehouse stock levels as a means to better manage inventory. We use different pricing models as a framework to aid in the analysis. Such models as CAPM and APT aid in figuring out the levels of risk involved with both projects. For financial professionals it is of utmost importance to assess risk as accurately as possible in order to sell in this case the project. Companies are more than often risk adverse and do not want to take a loss with the money invested. In this respect most companies enjoy a conservative approach, which means the less risk involved the better. Because APT builds upon CAPM and takes the theory to a new level, it requires further analysis to prove the point. Still first in order to understand APT, one must first have a grasp of CAPM works. CAPM can only work to assess risk in the long run scenario. CAPM also assumes the investor does not have inside knowledge and that the Beta is known. This is the only way an expected return can be determined with CAPM. Mark McCracken defines Beta as â€Å"equals 1.0000. 1 exactly. Each company also has a beta. A companys beta is that companys risk compared to the risk of the overall market. If the company has a beta of 3.0, then it is said to be 3 times more risky than the overall market† (par. 1). For this scenario each project has a beta. The amount of risk and the type of risk can be determined by diversification. Systematic risk, which is market risk or undiversified risk, is the portion of an assets risk that cannot be eliminated via diversification. The systematic risk indicates how including a particular asset in a diversified portfolio will contribute to the risky nature of the portfolio. Unsystematic risk, which is firm-specific or diversifiable risk, is the portion o f an assets total risk that can be eliminated by including the security as part of a diversifiable portfolio (Mathis, par. 1). So obviously there are some projects that will not be included in a diverse portfolio because of its defined risk under this theory. CAPM digs deeper to assess for an expression, which relates the expected return on an asset to its systematic risk. This in turn gives the financial professional better idea of the project’s risk behaviour. The equation used is as follows: (Mathis, par. 3) The measure of systematic risk is considered Beta or bi while E[Ri] is equal to the expected return on asset I and Rf is the risk-free rate. E[Rm] is the expected return on the project and E[Rm] – Rf is the market risk premium for the company stock. Once the Beta is known then the risk and rate of return can be found. APT is different because not only can forecast for the long term, it can also work for the short-term scenario. This fact makes it the better of the two theories because it gives the financial professional more tools to assess risk and the rate of return. APT does this by using a model that captures all the data. Other things this model can perform for risk assessment take into account company needs. Risk Estimates such as Tracking Error, Value-at-Risk (VaR), forecast volatility, systematic active risk, beta to benchmark, correlation with benchmark. APT carries out these calculations in a linear framework with a number of different variables. This is how different time frames can be used. For the APT model there are several outside factors to take into account. The ‘Now’ asset is defined by a number of beta possibilities, each of them representing asset sensitivity to a particular factor and characterizing systematic risk associated with this factor, and, as before, residual yield E. In this respect the risk allotted to this particular venture is less. This multi-factored model brings up many questions for the finance assistant. One thing to keep in mind is that not all factors carryover to risk in this area. There are factors that remain assets to an organisation faced with such decisions. This is one reason why periods of growth need solid leadership. This effectively assesses the risk involved for the furniture company’s returns. The NPV is assumed as the present value of the projects cash inflows minus the present value of the projects cash outflows (Mathis, par. 2). This relationship is expressed by the following formula: (Mathis, par. 2) TASK FOUR: Production and Profitability Your company is considering purchasing another machine due to the increase of production of furniture products and advanced sales of select models featured in the current marketing scheme. You are faced with figuring out if purchase of the machine is a profitable idea and if so what is the long-term cost? And how should it be funded? There are factors one is aware of when purchasing a new piece of equipment. Revenues will not change if the machine is purchased. Both the present machine and the new machine will last 5 years and will have no disposal value in five years. The new machine will cost  £400,000. The old machine can be disposed of right now for a disposal value of  £10,000. The new machine will reduce operating costs by $ £100,000 per year (assume cash flows at the end of the years). Assume a required rate of return or discount rate of 9%. Is it feasible for the company and cost effective? From the standpoint of long-term investment, it seems the new machine will be a valued addition to the team and allow production to not only run at current levels but also maintain new levels of efficiency. Also because it is considered a long-term investment, the company should also consider it an investment and possibly obtain a credit line for the local bank to cover this asset. In this way, the company can also apply for extended warranties to cover any maintenance or break down of the machine over the life of the loan. If the company has prime credit, a low interest rate of 6% is guaranteed and look into possible incentives with the local bank as a regular customer who pays on time, it may be possible to reduce the interest if there is not a pre-payment penalty. Suffice it say, there is cash flow that could be allocated for the purchase but also used for reinvestment in other areas of the company. Traditionalists will want to pay as much upfront as one can but if the long-range benefit outweighs the short-term loan, then by all means allow the company a li ttle space to get ahead with the new machine. Like above the net present value for the machine can be determined with the following equation. The NPV is assumed as the present value of the projects cash inflows minus the present value of the projects cash outflows (Mathis, par. 2). This relationship is expressed by the following formula: (Mathis, par. 2) TASK FIVE: Buying Out and Merging Every business needs planning or a defined strategy in place for future growth and control of known issues. There is a certain amount of power that comes from knowing what’s next. Smaller firms are vital to the economic health and stimulus of the world, mainly western nations like the United States and those found in Europe. Much of the success of these firms falls into the hands of leaders involved with everyday management but also the planning for future generations. Sir Adrian Cadbury writes, â€Å"Firms form the basic building block for businesses throughout the world. The economic and social importance of regional family enterprises has now become more widely recognized† (p. 5). In fact, it has been found that many firms do not survive the transition a generational business can represent. Many do not see life after the transition, which leads to decreased economic mobility and health. With this in mind, it is very important to have a transition strategy in place. T his requires proactive information sharing with all members even if some are not directly involved with day-to-day operations. This will ease the burden of conflict that may arise later. As with any organisation, knowledge management is key to good communication but with a small firm also instrumental for a successful future. This leads one to wonder how the structure of a smaller firm may differ from larger corporations? Is there a chain of command? How does leadership work?   It seems recently the trend of one company buying out another or merging to become one larger company is on the rise. It is in the news everyday, only drawing minimal concern from the public as regulators call into question the legality of such actions. Do mergers and acquisitions make the world a better place for consumers or do they just offer less for the consumer to choose from in the marketplace. It seems that most large companies see this practice as a means of redefining the marketplace by getting rid of the competition and making the competition work for them. In this respect, governments are able to make the rules of the merger and acquisition, setting the standard by which products of both companies can continue to compete with each other in a given market. This in turn, fuels the fire for increased advantage, working toward the goal of ultimately feeding off each other’s energy until it is exhausted. One finds this type of government control more in telecommunicatio ns and banking than other industries. For the retail industry, it seems a foregone conclusion that eventually opportunities will present themselves. From the looks of their balance sheets of Furniture Concepts there is a reason the company seeks a merger with another company. There seems to be a large amount of sales but not enough profit being generated. Within the last year their expenses have tripled but the production has not. They look to be in trouble. Another concern is founded within their name it self. Why call them selves a Furniture Concepts store when they sell carpet? It should be Carpet Concept. It may be that they have diversified their production schemes so far that this amounts to the increase of expenses? The recommendation would be to acquire the company, keep high performing employees on board and cut the lard. Expenses may also be attributed to bad debts acquired to maintain production or inflated management salaries? This would be a good move for the organisati on and also allow our furniture store to diversify without much overhead or inventory issues. CONCLUSION An organisation needs a clear picture of financial health in order to maintain operations and continue a path of growth toward market share. Many things go into deciphering this financial status. Part of what has happened here is a need for new tactics that are tried and true but without great risk affiliation like the credit offer. This strategy while well meaning for the short term has caused long-term ramifications for the organisation starting with growing pains. Lastly, research shows that the greatest obstacle to accepting new policies is fear of change. Therefore, this makes the transition period crucial and should be handled with kid gloves by management. Communication should be open and clear. REFERENCES 2003, ‘Capital budgeting needs vision’, Business Line, Islamabad, 21 July.

Animal Rights Speech :: essays research papers

Our case is that if we don’t test on animals then progress in scientific fields would be halted. As first speaker for the negative I will speak about the benefits of animal testing in general and then I’ll talk in detail about animal testing in medicine. My second speaker will talk about the opinions on testing and the food chain and my third speaker will summarise our points and rebut. Safety tests are conducted on a wide range of chemicals and products, including drugs, vaccines, cosmetics, household cleaners, pesticides, foodstuffs, and packing materials. Higher order animals are used in research, teaching and testing because of the benefits they bring to both animals and people. Those benefits are the reasons why a research, teaching or testing procedure is done in the first place. Research using animals has various broad aims which include: Safety tests are conducted on a wide range of chemicals and products, including drugs, vaccines, cosmetics, household cleaners, pesticides, foodstuffs, and packing materials.

Doctors, nurses, animal care personnel, veterinarians, farmers, conservation managers, teachers, zoo keepers and others engaged in animal-related activities all benefit in animal research to broaden their knowledge. Testing is done as a check on the safety of new drugs or substances for human or animal use, and to check whether new batches of drugs and other agents like vaccines work. There is a legal requirement to test how safe and effective chemicals, drugs and other agents are before they can be sold. Animals have played a major part in medical breakthroughs. Such as the development of anesthetics, which are the chemicals used to make you unconscious during an operation. . Before that surgery was little more than refined butchery. Amputations, removal of bladder stones, caesarean sections and others – were done with the conscious patient strapped to the operating table and screaming.

Pablo Picasso Essay -- Essays Papers

Pablo Picasso Some say he was superstitious, sarcastic, awful towards his children, and horrible to women. He could very well have been all those things, but one thing I know Pablo Picasso was a great artist. He is one of the fathers of cubism, he had an audience of at least tens of millions. No other painter or sculptor before him had the fame that Picasso had. In the year 1881 a son was born to Don Jose Ruiz Blasco and Maria Picasso on the southern coast of Spain in a town called Mà ¡laga. At around the age the age of 10 his father because an instructor at Da Guarda Institute. A year later young Pablo was being taught by his father. In a short time he started writing and illustrating a journals. When he was 16 he moved to Barcelona and excelled at the La Llotja Fine Arts Academy and was soon accepted by the Royal Academy in Madrid. He was often regarded as a boy genius. By 1901 Picasso began to paint entire works in tones of blue. This was appropriately called the Blue Period. The Blue Period was mostly beggars and â€Å"circus folk†. They always seemed to be lost in contemplation. This was a confidant step to Picasso maturity. Gradually his colors brightened. This era in his career was called the Rose Period. But he didn’t just use red as he only used blue in the Blue Period. In the Rose Period not only did he use soft pinks, but also blues, reds and greens because they created great compliments these images created. Picasso was neither a philosopher ...
