Physics Space Time Trajectories - 991 Words

Space-time trajectories approaches are established on the observation that the tracking of joint positions is sufficient for humans to recognize actions [26]. Trajectories are usually formed by tracking joint points or other interest points of the human body. Various trajectories representations and corresponding matching algorithms used the for action recognition. Space-time Trajectories based approaches interpret the human activity as a set of space-time trajectories. A person is generally represented as a set of 2-dimensional (XY), 3-dimensional (XYZ), or 4-dimensional (XYZT) points corresponding to his or her joint positions along the space and time. Human body parts estimation methodologies, especially the stick figure modeling, are widely used to extract the joint positions of a person at each image frame. Changes in joint position of a human performing an action are recorded as space-time trajectories, constructing 3-D XYT or 4-D XYZT representations of the human activity. Figure 2.6 shows example trajectories. Figure 2.6-a shows 3-D XYZ trajectories, while figure 2.6-b shows 3-D XYT trajectories. The early work done by Johansson [26] in 1975 suggested that the tracking of joint positions itself is sufficient for humans to distinguish actions, and this paradigm has been studied for the recognition of human activities in depth [27,28] Various approaches used the trajectories themselves (i.e. sets of 3-D points) to represent and recognize actions directly [29,30].Show MoreRelatedApollo 13 Movie Physics Essay1035 Words   |  5 PagesApollo 13 Essay Have you ever wondered what it would be like to fly in space or work on the crew at NASA that helps the astronauts get home safely?

The No Child Left Behind program Education is a key contributor to personal development social and economic growth. It is obligatory for a person to be educated and trained effectively In order to achieve his or her ambition. Educators and trainers play a leading role in the making of future leaders and champions. Such are the principal aspects, which led to the rise of the No Child Left Behind program in 2002. The program, which focuses on teaching practices, is meant to enhance excellence in students attending all education centers giving no bias to nationality, gender, physical, or mental disability (Berkhart 84). The program, which has been running for at least 1 decade, benefits many learners due to its remarkable contribution to academic excellence and skill empowerment in relation to establishing a brighter future for the young generation. No Child Left Behind program advocates for child educational welfare. The program ensures that students excel in their studies, and promotes fair and equal access to educat ion for all (Abernathy 98). The main goal for the No Child Left Behind program is to ensure that all students perform well in school. Hence, it is mandatory for teachers to assess students annually without bias.

Of course, nuclear explosions, power sources, â€Å"lawlessness† of computers and lasers, new materials show that the focus of interest of scientists extends far beyond the â€Å"fragments of the last century. † However overact image of the scientist, and the whole science – tenacious. Although little can be so far from the truth as painting created impressionable and ardent poet. We will write a custom essay sample on Physics and Science or any similar topic only for you Order Now Even when Mayakovsky wrote his verse, and in science and around Shakespeare’s dramas quite scale. To be understood correctly, I should note that the question â€Å"To be or not to be† as applied to humanity and not the individual, though considerable, was first raised by physicists precisely and on the achievements of physics. It’s not by chance that for about three centuries were marked by the science. People involved in it, opened and opened the fundamental laws of nature that determine the structure and movement of material objects in a large range of distances, time and mass. Ranges of these great – from the small, atomic and subatomic to the cosmic and universal. Of course, this is not physics said â€Å"Let there be light,† but they found its nature and properties, set contrast to the darkness, and have learned to manage them. In its work, physics, crucially the largest of them, have developed a certain way of thinking, the main elements of which is the willingness to rely on well-tested, fundamental laws and the ability of a complex nature, and the public, a phenomenon highlight the main element, as simple as possible, that allows us to understand the very complex phenomenon under consideration. These features allow physicists approach very successfully deal with problems often lie far beyond their specialization. Confidence in the unity of the laws of nature, based on extensive experimental material, confidence in their fairness, coupled with a clear understanding of the limitations of the applicability of existing laws physics pushes forward, abroad unknown today. Physics – the science is complicated. It requires a lot of intellectual effort from the people who do it. It is incompatible with the amateurish. I remember how, at the end of the University and the Shipbuilding Institute in 1958, I was standing at the crossroads – where to go next. And my father, very far from science, asked me if I could go back to engineering after a dozen years of studying physics. My answer was an unqualified â€Å"yes. † â€Å"In physics, after ten years of engineering? â€Å", – He said. My â€Å"no† and identified a further choice, which is not sorry and I do not regret a second. The complexity of physics and the importance of its results that create a picture of the world and encourage the spread of its ideas far beyond most of this science in the public interest to her. I will give some of these ideas, in the order received. This is a scientific (not speculative! ) Atomism, the opening of the electromagnetic field, the mechanical theory of heat, the establishment of the relativity of space and time, the concept of an expanding universe, and quantum leaps in principle, not because of the error, the probabilistic nature of the physical processes in the first place, the micro- level, the grand unification of all interactions, establishing the existence of not directly observable subatomic particles – quarks. Here then there are popular books that are designed not to teach physics beginners, and explain her interest. There is another purpose of popular books, including the very well-known to people of my generation is â€Å"Entertaining Physics† Yakov Perelman, not relative ME Perelman. I am referring to a demonstration of how much things in everyday life, familiar to us technique and technology, one can understand qualitatively, based only on the well-known fundamental laws of physics in the first place – the law of conservation of energy and momentum, and the confidence that they are universally applicable. Objects of the laws of physics are vast. Why not pour water into the boiling oil, why stars twinkle in the sky, why is twisted water, emerging from the bathroom, why crack the whip and why the driver spins it over his head, to enhance the sound of the click, why ever would try to jump off the rail locomotives, but never make it electric? Why roars menacingly approaching plane and moving away, he moves to a falsetto, and why dancers or figure skaters begin to spin, throwing open wide â€Å"arms,† but then quickly pressed his hands to the body? Of the â€Å"why† of each in everyday encounters, not to mention not everyday life in abundance. They may be useful to learn to see, train yourself to find incomprehensible. Books by E. Perelman contain a record number of such questions â€Å"why? † (Five hundred), give them the answers, in most cases – definitely right, sometimes – beckoning to the discussion, occasionally – probably incorrect, provoking disagreement. There are questions that science has to date simple and generally accepted answer. Hence, the reader is room for an intense intellectual work. Along the way, the author explains the ell-known professionals to but less severe confusion among outsiders. That is, the author emphasizes the operational nature of many of the definitions in such a universally recognized exact science like physics. Professionals know that even the most fundamental of concepts, which operates physics, such as time and energy, space and momentum adjusted as fur ther development of science itself. Even the vacuum, once the analogue of absolute emptiness, lack of anything was self-evident in the â€Å"empty† space in time â€Å"overgrown† means non-trivial features of the primitive raises complex object of study. Versatility physical approach dictates a similar attitude to the definitions of non-trivial concepts and other areas that are very far from physics. Read books mentioned ME Perelman interesting and professionals – to argue, to find other, allowing a simple, sometimes graphic, explaining the issue. But a layman can expand your horizons, not necessarily rushing to their own, different from the author, explanation. It is worth remembering that the writing – verbal impression, often greatly simplified, with sometimes very complex physical concepts, based on a far from trivial in the everyday sense of the physical theory. You read "Physics and Science" in category "Papers" No need to follow the example of the real character, the director of one of the Moscow Research Institute who denied particular theory of relativity (general he chityval! ) Because the formula is the speed of light! â€Å"What would happen if the light off? † – Wrote in the science department of the Central Committee of the CPSU venerable gunmaker. Studying physics, beginning to understand its laws, shall be attached to the special beauty, there is actually an extra dimension to the perception of the surrounding world. This was written when – the great physicist Richard Feynman, noting that understanding the nature of the glow of stars, the mechanism of their birth and death makes the picture night sky even more beautiful and romantic. I wish, in conclusion, to mention one, a few unexpected side benefit of knowledge of physics, though by no means superficial. About him once told Academician Migdal. It lights up in the mountains and attractions nearby couple. The young man explained his pleasant companion, why daytime sky is blue. He told her about the scattering of light, referred to Lord – theoretical Rayleigh. The girl was sitting with his mouth open, looking admiringly at the scholar. But of the bore, and he, showing carelessness and inattention to a senior, said that the probability of scattering of radiation is proportional to the cube of the frequency. Migdal but was already on the alert. Remembering a classic, it is appropriate only in a very weakened form, say, perhaps, academic â€Å"in thought, under the night darkness, mouth kiss the bride. â€Å"Young man, the probability of scattering can not be proportional to the cube of the frequency – it would clearly be contrary to the invariance of the theory with respect to time reversal. The relay, as it should be, the probability is not proportional to the cube, and the fourth power of the frequency! † – In his usual tone, dogmatic said Migdal. Needless to say, that triangle changes shape, and the fat was cathetus hypotenuse, reaching the top. In short, read about physics and who is not too late – learn it. It will pay off. Physics in Medicine Medical physics – the science of the system, which consists of the physical devices and radiation, medical diagnostic equipment and technology. The purpose of medical physics – the study of these systems for prevention and diagnosis, and treatment of patients using the methods and tools of physics, mathematics and engineering. Nature of the disease and the mechanism of recovery in many cases have biophysical explanation. Medical physicists are directly involved in clinical processes, combining physical and medical knowledge, sharing with the doctor responsible for the patient. The development of medicine and physics have always been closely intertwined. Even in ancient times medicine used for medicinal purposes physical factors such as heat, cold, sound, light, and various mechanical actions (Hippocrates, Avicenna and others). First medical physicist, Leonardo da Vinci (five hundred years ago), who conducted the study of mechanics of movement of the human body. The most prolific medicine and physics were to interact with the end of the XVIII – XIX centuries. , When they were discovered electricity and electromagnetic waves, that is, with the advent of electricity. To name a few names of great scientists who have made important discoveries in different epochs. End of XIX – the middle of the twentieth century. connected with the discovery of X-rays, radioactivity, theories of atomic structure, electromagnetic radiation. These discoveries are associated with the names of C. Roentgen, Becquerel, M. Sklodowska-Curie, D. Thomson, Planck, Bohr, Einstein, Rutherford. Medical physics has truly establish itself as an independent science and profession only in the second half of the twentieth century. – With the advent of the atomic age. In medicine, have been widely used radiodiagnostic gamma apparatus, electronic and proton accelerators radiodiagnostic gamma camera, CT scanners, and others, hyperthermia and magnetic therapy, laser, ultrasound, and other medical and physical techniques and instruments. Medical physics has many sections and titles: medical radiation physics, clinical physics, physics oncology, therapeutic and diagnostic physics. The most important event in the field of medical examination may be the creation of CT scanners, which have broadened the study of almost all organs and systems of the human body. OCT have been installed in hospitals around the world, and a large number of physicists, engineers and doctors worked on improving techniques and methods of bringing it almost to the limits of the possible. The development of nuclear medicine is a combination of methods and physical methods radiofarmatsevtiki registration of ionizing radiation. Positron-emission tomography imaging was invented in 1951 and published in the paper of Rennes. Physics and literature In life, sometimes without realizing it, physics and literature are closely intertwined. Ever since ancient times, people in order to convey to posterity literary word, used the invention, based on knowledge of physics. On the life of the German inventor Johannes Gutenberg is little. However, the great inventor, to convey to us the literary masterpieces studied the laws of physics and mechanics. Organized them in printing, he published the first book in Europe, which has played an important role in human development. The first Russian printer – Ivan Fedorov, was known to contemporaries as a scientist and inventor. For example, he was able to cast cannon invented multilateral mortar. A first remarkable images of the literary and art of printing – â€Å"The Apostle† (1564) and â€Å"Chasovnikov† (1565) will remain forever in people’s memory. The name of Mikhail Lomonosov we call one of the first in the series of the most remarkable representatives of the national science and culture. The great physicist, he left a number of works that are important for the industrial development of Russia. A large part of his scientific work took optics. He manufactured optical instruments and original mirror telescopes. Exploring the sky with their instruments, inspired by the infinite universe, Lomonosov wrote beautiful poetry: Opened an abyss full of stars. The stars of not, the abyss – the bottom †¦ Without such a science as physics would not be a literary genre as science – fiction. One of the founders of the genre was the French writer Jules Verne (1828 – 1905 gg. ) Inspired by the great discoveries of the XIX century, the famous writer surrounded physics glamor. All of his book â€Å"From the Earth to the Moon† (1865), â€Å"The Children of Captain Grant† (1867-68 gg. ), â€Å"20,000 Leagues Under the Sea† (1869-70 gg. , â€Å"The Mysterious Island† (1875 . ) are imbued with the romance of this science. In turn, many inventors and designers inspired the incredible adventures of heroes of Jules Verne. For example, the Swiss scientist – physicist Auguste Piccard, like repeating the path of fantastic characters he invented climbed into the stratosphere stratosphere, making the first step towards uncovering the mysteries of cosmic rays. The next fad A. Piccard was the idea of the conquest of the sea depths. The inventor himself sinking to the sea floor and to build them bathyscaphe (1948). For about 160 years ago in â€Å"Notes of the Fatherland† published â€Å"Letters on the Study of Nature† (1844 – 1845). Herzen – one of the most important and original works in the history of philosophy as well as natural science, Russian thought. Revolutionary, philosopher, author of one of the masterpieces of classical Russian literature works â€Å"My Past and Thoughts† – Herzen, however, was keenly interested in the natural sciences, including physics, he has repeatedly stressed in his writings. Now you need to turn to the literary heritage of Tolstoy. First, because the great writer was a teacher – the practice, and second, that his works relate to the natural sciences. Best known for the comedy â€Å"The Fruits of Enlightenment. † The writer is extremely negative attitude â€Å"to all kinds of superstitions,† he believed that they â€Å"hamper and hinder the true teaching it to penetrate into the soul of the people. † Tolstoy understand the role of science in society: first, he was a supporter of the organization of society on sound science, and second, it makes a powerful emphasis on the moral – ethical standards, and because of this science in the treatment of Tolstoy are secondary science . That is why Tolstoy ridiculed in â€Å"Fruits of Enlightenment† Moscow gentry in the heads of which are mixed science and Antiscience. I must say that at the time of Tolstoy on the one hand that time, physics is in deep crisis due to the experimental verification of the main tenets of the theory of the electromagnetic field, which disproved the hypothesis of the existence of Maxwell’s world ether, that is, the physical environment, which transmits electromagnetic interactions Of course, nuclear explosions, power sources, â€Å"lawlessness† of computers and lasers, new materials show that the focus of interest of scientists extends far beyond the â€Å"fragments of the last century. † However overact image of the scientist, and the whole science – tenacious. Although little can be so far from the truth as painting created impressionable and ardent poet. Even when Mayakovsky wrote his verse, and in science and around Shakespeare’s dramas quite scale.

Strategic Marketing Management Samples for Students †MyAssignmenthel

Question: Discuss about the Strategic Marketing Management. Answer: There are two kinds of external marketing environments; micro and macro. These environments factors are beyond the control of marketers but they still influence the decisions made when creating a strategic marketing strategy. Micro environment factors include the suppliers, resellers, customers, competition and general public. Macro environment factors include demographic, economic, natural, technological, political, legal, social and cultural forces. The marketing strategies differ depending on the type of individual business and target market. Michael Porter along with his five forces of Competitor Analysis categorized generic market strategies. His strategy revolves around the dimensions of strategic scope and strategic strength. Marketing Mix is also a very famous term in marketing planning process and also known as 4 P's or in some cases 7 P's of marketing (Pulizzi 2014). With an understanding of the business' internal strengths and weaknesses and the external opportunities and threats, one can develop a strategy that plays to his/her own strengths and matches them to the emerging opportunities. One can also identify the weaknesses and try to minimize them. The next step is to draw up a detailed marketing plan that sets out the specific actions to put that strategy into practice. This includes the changes taking place in the organizational environment, opportunities and threats and more. Before looking at new markets, it is important to think about how the company can get the most out of your existing customer base - it's usually more economical and quicker than finding new customers (Hair Jr and Lukas 2014). When it comes to creating asuccessful marketing strategy, setting clear objectives is essential to the plan's success.Considering the marketing plan or strategy from all angles is necessary when creating your objectives, as there are various distinct types of marketing objectives. There are four main types of marketing objectives: A profitability objective determines the amount of expected income based on the promotional strategy. Market share objective determines how much of the market the company wishes to gain. A promotional objective is the desired level of product or service awareness. Growth objective determines the current business size and how much the company wishes it to grow (Babin and Zikmund 2015). Strategy Formulation begins with an analysis of the forces that shape competition in the industry in which a company is based. The goal is to understand the opportunities and threats confronting the firm and to use this understanding to identify strategies that will enable a company to outperform its rivals. Opportunities arise when a company can take advantage of conditions in its environment to formulate and implement strategies that enable it to perform more profitable. Threats arise when conditions in the external environment endanger the integrity and profitability of the company's business (Jobber and Ellis-Chadwick 2012). Components of Marketing Environment There are two types of marketing environment or it can be said that two such components in which a company operates i.e. the external environment and the internal environment. As required in the question, the impact of the external environment changes is explained in detail below: The external environment is the environment that poses a direct influence on the company. Though the components of this environment are not a framed part of the company, but their existence in itself is either a boon or a threat to the company. The components of such environment are customers, suppliers, shareholders, competitors, political environment, social environment, marketing environment, cultural environment in which the company operates. All these components can be divided into micro and macro components depending on the overall affect they have on the company (Hair Jr and Lukas 2014). Another such tool that analyzes firms internal resources is VRIO analysis. According to this tool, the resources must be valuable, rare, imperfectly imitable and non-substitutable. VRIO analysis stands for four questions that ask if a resource is: valuable? rare? costly to imitate? And is a firm organized to capture the value of the resources? A resource or capability that meets all four requirements can bring sustained competitive advantage for the company (Rollins, Anitsal and Anitsal 2014). The Internal Analysis of strengths and weaknesses focuses on internal factors that give an organization certain advantages and disadvantages in meeting the needs of its target market. Strengths refer to core competencies that give the firm an advantage in meeting the needs of its target markets. Any analysis of company strengths should be market oriented/customer focused because strengths are only meaningful when they assist the firm in meeting customer needs. Weaknesses refer to any limitations a company faces in developing or implementing a strategy. Weaknesses should also be examined from a customer perspective because customers often perceive weaknesses that a company cannot see (Pulizzi 2014).

In the twentieth century rapid economic development has resulted in environmental jobs. Hence, environmental pollution has been a cause for concern for the past few decennaries. The nursery consequence caused by the release of C dioxide for illustration has become a chief focal point in the universe. Newspaper headlines, academic stuff and protests by assorted environmental militants have forced each one to be cognizant of their duty towards to environment. There has been an increasing divergency in the positions between ecologists and economic experts whereby the ecologists have a really pessimistic position of the environment in the hereafter, where they believe that the resources are consuming at really fast rate ; on the other manus the economic experts have an optimistic position. Supported by statistical grounds the economic point of position for the hereafter suggests that poorness degrees are cut downing, the natural resources will last for another 150 old ages We will write a custom essay sample on Critically evaluate two approaches to solving the problems of environmental pollution. specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Critically evaluate two approaches to solving the problems of environmental pollution. specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Critically evaluate two approaches to solving the problems of environmental pollution. specifically for you FOR ONLY $16.38 $13.9/page Hire Writer The undermentioned paper will analyze the effects of pollution and the steps that have been taken to battle it. The sign language of the UN clime alteration model pact indicates that environmental protection is being taken earnestly and that people around the universe have reached a decision about the demand to command the fumes of nursery gases, such as C dioxide, ensuing in betterments in the environment and recognizing sustainable development. Amongst the assorted definitions provided for pollution, one of the defines pollution as, â€Å"†¦the release of harmful environmental contaminations, or the substances so release.†[ 1 ] The fact must be noted that the substances themselves are non harmful, but when they are converted into smog due to solar energy ( sunlight ) that they have a harmful consequence on the environment and cause wellness jeopardies. Pollution is the consequence of ( negative ) human activity. There are two chief sorts of pollution – local and planetary pollution. Earlier pollution at the local degree was considered to be the lone job. Local pollution took the signifier of firing coal bring forthing fume and being risky for wellness. The attack to undertake pollution in the developed universe was to develop consciousness at the school degree. However, when some signifiers of pollution has a planetary consequence it is termed as planetary pollution. Besides whether something is pollution or non depends on the context it is being used. For case C dioxide emanations are referred to as pollution due to the harm they cause to the ambiance ensuing in climatic alterations. Other illustrat ions of pollution beginnings include atomic workss and oil oilers let go ofing toxic waste into the environment. Traditional signifiers of pollution include noise, air and H2O pollution. [ 2 ] Prior to analyzing the attacks to work outing the job it is indispensable to understand the harmful effects of pollution. On assorted foreparts it has been argued that environmental pollution consequences in serious wellness jeopardies like increased hazard of malignant neoplastic disease, skin harm, interrupting the ecological balance and upsetting the climatic equilibrium. Nowadays everything ramping from drouths, inundations, and temblors to the gradual displacement in climatic alterations, for case, colder states anticipating abnormally high temperatures during summers, is being associated with pollution. Theorists have argued that there is small grounds to propose whether the alteration in clime will be a good thing or a bad thing. It is the perceptual experience that people have or that has been created by media that everyone believes that climatic alterations will non be contributing for economic growing. Tacking the job of pollution has become a major concern for everyone. In economic theory ; markets coordinate the picks of people with respect to natural resource usage ; nevertheless ; environmental determinations are made outside the market and without cognition of the to the full priced goods and services. Gwartney et. Al ( 2000 ) place the absence of clearly defined and firmly enforced belongings rights and the ensuing deficiency of markets and decision-makers answerability as the nucleus issues of pollution and other outwardness jobs. They believe that authoritiess need to inquire themselves whether economic growing is harmful for the environment. Economic growing by and large leads to environmental betterments because people with higher incomes are willing to pay more for environmental quality. Gwartney et. Al ( 2000 ) argue that the demand to take between economic growing and environmental quality may look obvious when economic activities affect the quality of the air or H2O. Governments in the developed states are under force per unit area from conservationist to protect the rights of those able to turn out that they have been harmed by pollution. Surveies conducted by Donald Cursey finds that US and in other industrial states citizen’s support for steps to better environmental quality is extremely sensitive to income alterations. [ 3 ] Thus in economic footings, willingness to pay for dearly-won environmental steps is extremely elastic with regard to income. Income growing helps to increase the demand for environmental quality, while technological progresss help to take down the cost of cut downing both resource usage and pollution. Yet incomes above the poorness degree and an apprehension of the engineering are non plenty to protect the environment. The job posed by pollution can be explained by utilizing the theory of market failure, which occurs when resources are non expeditiously allocated. This theory highlights the jobs faced by concerns ( manufacturers ) who feel that the cost of disposing waste is excessively high and that net incomes will be higher if costs are kept to a lower limit and disposing of waste through a least cost method is extremely efficient. Therefore harmonizing to the theory of market failures, the true cost to the society is much higher than the private cost of the manufacturer. Solving THE CRISIS In the UK, the Environment Agency is responsible for the protection and betterment of the air, land and H2O. The study that hey published suggested the overall incidents of serious pollution were 20 % lower than in 2001. The cardinal industries responsible for the pollution of H2O, land and air are agribusiness, waste direction, the H2O industry and the chemical industry. But repeat wrongdoers included companies such as BP UK, Tesco, Tiles-R-Us, TotalFinaElf, Anglian Water, Thames Water, BT, Yoplait and Stationary Box. [ 4 ] It is a flooring disclosure to see the names of companies like Tesco and Tiles-R-Us in the list of pollution wrongdoers. Therefore when companies which deal with harmless merchandises like nutrient can besides terrible harm to the environment, H2O companies and agrarian activities would be doing so much more injury. One manner to battle the job of halting companies and concerns from fouling the environment has been to impose mulcts. Harmonizing to the study published, the mean all right per company was raised by over one 3rd to ?8,744. Fines of more than ?20,000 rose by about 42 % compared to 2001 but the Environment Agency believes that the size of the mulcts are non sufficient to carry companies to alter their behavior. Amongst the assorted illustrations cited, one of them indicated how a company manager dumped dirt incorporating arsenic, quicksilver and nitrile, which has serious wellness deductions as it can do circulatory jobs, skin harm and increased hazard of malignant neoplastic disease. The sentence given to the manager was that he was jailed merely for one twelvemonth. Sing that his act could hold resulted in many human lives enduring from terrible wellness jobs and the punishment of merely one twelvemonth of gaol sentence does non look to be just. It would non be right to fault the companies and concerns for non following with the ordinances. Businesss tend to reason that the systems and support construction is non in topographic point for them to dispose waste safely. In the absence of a proper substructure to make so, it would be incorrect to set the incrimination merely on one party. Another factor that discourages concerns from safely disposing waste is the cost factor involved. It has proved to be really expensive for concerns to dispose waste. This is particularly the instance in agriculture, where borders are tight. Regulation Government ordinance is an alternate method of seeking to protect and continue the quality of the environment. Regulation nevertheless does non ever lead to ideal results, and it can be tremendously expensive. Regulation is non ever based o market systems, so it is capable to all the jobs associated with deficiency of information and deficiency of inducements that have plagued the socialist states. For case, in the instance of planetary heating, emanations from C dioxide from efficient combustion of all fuels instance no injury where they are emitted. No one’s rights are being violated by the invasion of harmful pollutant, yet these emanations are constructing up in the ambiance. Therefore this may necessitate that in the future ordinances must take this into history. Some scientists and environmental groups argue that the menace of planetary heating is serious and that despite high costs, the states of the universe must enforce strong ordinances rapidly. Many states have initiated air pollution control programmes in recent old ages. In England control was started by the establishment of smokeless zones and by controls based on the coloring material of the emitted fume and great motion has doubtless resulted. In Ontario, a more extremist attack was adopted, by set uping an discoverer of fouling beginnings and forbiding the puting up of new industrial concerns without an in agreement system of emanation control, and besides by mensurating the ‘air pollution index Various unfavorable judgments have been offered in footings of how pollution control steps are designed and implemented. It has been argued that frequently the Some theoreticians believe that cut downing degrees of environmental pollution is non merely the duty for companies, but besides a societal duty of each and every occupant ; it can merely be possible if the persons besides portion the cost that is borne by manufacturers, by paying higher monetary values for the services and goods. The principle offered is that in return for higher monetary values, non merely is the single being offered better merchandises but besides a cleansing agent environment. It can be argued that even though it seems rational ; to bear down consumers higher monetary values for a safer environment, but it must be noted that companies gets subsidies, revenue enhancement benefits and many other signifiers of the authorities support which helps them to get by with the increased investing in engineering to bring forth environment friendly merchandises, nevertheless, single consumers are non paid higher rewards and wages to purchase environmentally friendly environme nt. The thought is to keep those people responsible who pollute the environment and do enforce some signifier of fiscal punishment. Some do believe that the solution by concentrating on doing the monetary value signal work more efficaciously, by taxing the manufacturer and supplying him with some signifier of fiscal inducement to put in would ensue in would be an extension of belongings rights and are all possible methods to battle the job of pollution. Other possible methods that have been suggested are to publish tradable licenses. The thought is that licenses would let manufacturers to foul up to a certain degree. The licenses will besides assist in increasingly cut downing the overall degree of pollution. Property Rights In the UK, attempts are being made to widen the belongings rights. The implicit in thought of belongings rights is that if person is found to be doing harm to person else’s belongings, legal action can be taken against the person. In the environmental sense, Environment Agency has been set up who has ownership over the environment so to talk. In the US, Environmental Protection Agency ( EPA ) is one of the many administrations that have been set up to accomplish the above mentioned purpose. Property rights give legal standing to those who are threatened by pollution. Owners of land and other resources in a market economic system have the right to action anyone. Significant part to environmental quality is made through the normal operation of belongings rights and a market system. However, it is sometimes hard to specify set up and protect belongings rights. In the instance of local pollution the belongings rights attack can cover efficaciously with the job, Most pollutants capable of doing serious harm are of this kind. However, if the effects of an emitted substance are both serious and widespread over a big population, or if the substance has many beginnings, so authorities ordinance may be more efficient. Policymakers and analysts sing environmental ordinances should recognize that environmental quality is an economic good. Like nutrient, vesture, and shelter, it is something that people are willing to pay for, though non in limitless sums. In add-on policy shapers should recognize that the nexus between environmental quality and economic prosperity is of import. Environmental ordinances can exercise a powerful influence. Policymakers should non bury that enforceable belongings rights were for many old ages the chief signifier of modulating environmental pollution and leting presbyopic persons and groups to exert their visions of preserved natural countries. Over all belongings rights continue to play a positive function in the saving of a quality environment. Evaluation Property rights provide inducement to the proprietor to portion resource entree, which resource monetary values provide users with the inducement to conserve. In add-on ownership ensures that the things under their ownership are good taken attention of. Furthermore, belongings rights provide long-run inducements for maximizing the value of resource. Thus for illustration, if eroding reduces a land’s hereafter productiveness, is value in present twenty-four hours footings would fall and would finally ensue in the diminution of the owner’s wealth. Advocates in favor of belongings rights argue that belongings rights are defined, defensible and tradable. They are considered highly of import for the smooth operation of markets. Therefore when belongings rights are present and protected, resource markets encourage handiness and they besides promote resource preservation. Arguments which are non in favor of authorities ordinance are that there is no strong grounds to propose w hether alterations in the earth’s cloud would make to heighten the warming effects of C dioxide or to countervail them. It is a general consensus of the scientists that the atmospheric theoretical accounts used to foretell planetary heating does non accurately integrate the effects of atmospheric H2O vaporization. Second, it has been questioned that for the past many decennaries added C dioxide has been associated with heating, but does this association mean that C dioxide caused warming. Further, it is besides being questioned if warming does happen would the sea degree rise or autumn. It is a known fact that warmer air carries more wet, and the added precipitation would construct up snow and the thickness of the ice on the polar caps would increase. It has been argued that pollution controls ( ordinance ) has inauspicious economic effects as it diverts the resources from other growing activities. Some have argued that ordinance can hold really inefficient ways of exerting control. Thirdly pollution control can hold a negative impact on investing. If the production of certain goods is made more expensive, it leads to a rise in the monetary values of these goods and therefore reduces the sum of each demanded. Second as these controls are levied on new beginnings, directors are likely to maintain old works in usage instead than replace it with new and more efficient installation. Protecting our environment does non hold to set an terminal to economic advancement. Free markets in licenses to foul, like free markets for other resources, can guarantee that pollution is controlled at the lowest cost possible. In drumhead it can be said that whether, the pick is made to utilize belongings rights or ordinances are used, they come with their set of advantages and disadvantages. Second, while the pick of belongings rights is making a sense of ownership and the chances of persons being more protective of something that they own is an interesting theory to star with. However, without ordinances being imposed from the authorities it would non be really effectual. Mechanisms would hold to be set in topographic point whereby the information is available to first of all assess the extent of harm and the costs involved. If the economic experts work on this based on the theoretical underpinning they would non hold entree to full information in footings of environmental harm while if the conservationists tend to work on the extent of harm they wouldn’t have complete information in footings of production costs etc. Thus what is required is a system where belongings rights are supported with ordi nance to undertake the job of pollution. Fine degrees need to be increased to do the cause of salvaging the environment more meaningful. Decision Pollution is a cause for concern for states around the universe. The intent is to command depletion of natural resources and guaranting that society becomes cognizant of its duty towards the environment. Amongst many steps offered to battle the pollution crisis authorities ordinance and set uping belongings rights are the two chief attacks discussed. From the predating paragraphs it can be seen that each of the two attacks have their ain sets of virtues and demerits. While some have argued that authorities ordinance is the right manner frontward, nevertheless, it must be noted that this system is non without its drawback of holding unequal information. On the other manus, set uping belongings rights has given more power to the bureaus like EPA and EA to enforce mulcts and fiscal punishments on those who are responsible for doing pollution. While the system has been considered to be better than enforcing ordinance, nevertheless it has been argued that the mulcts imposed are non large plenty to be seen as a ‘penalty’ . Furthermore, when higher costs are transferred from concerns to consumers in the signifier of bear downing higher monetary values, the system is farther questioned. Despite the statements offered, it is a applaudable attempt by authoritiess and conservationists in extenuating the effects of environmental pollution. A measure in the right enunciation is most of import than non doing any attempt at all. Thus both the attacks must be followed together and new systems should be developed to guarantee that the consequences are achieved sooner than subsequently.

Choosing a Coursebook and Teaching Materials for ESL

Choosing a Coursebook and Teaching Materials for ESL Finding the right coursebook is one of the most important tasks a teacher needs to undertake. This quick guide will help you in your decision-making process and point you to some of the resources on this site that can help you find the right coursebooks and supplementary materials for your course. Tips Evaluate the makeup of your class. Important considerations include the age, final course (are the students going to take a test?), objectives, and whether the class is made up of students learning for work purposes or for a hobby.If you are teaching a standard test course (TOEFL, First Certificate, IELTS, etc.) you will need to choose a coursebook that specifically for these tests. In this case, make sure to choose the coursebook based on the age of the class. Dont choose a book that prepares for another test as these tests are very different in construction and objectives.If you are not teaching a standard test course, are you going to teach a standard syllabus or do you want to focus on a specific area such as conversation or making presentations?Standard syllabuses require books that will cover grammar, reading, writing, speaking, and listening skills.If you are teaching a non-standard syllabus class, maybe focusing on one skill set, youll need to get some resource books for your classroom work. If you would like to take a different, non-grammar based, approach then take a look at either the lexical approach (focusing on building language skills from vocabulary and linguistic forms) or the Brain friendly approach (focusing on bringing a wide variety of learning types into play).If you are going to teach a Business English or ESP (English for Specific Purposes) course you will need to not only find a standard special English book but also use the Internet as a means of finding specific information and content related to the industry.You may also want to consider using the software as a means of extending the possibilities in the classroom.

Industrial Revolution Essay Example | Topics and Well Written Essays - 1000 words

Industrial Revolution - Essay Example section for cultivation. With their modern techniques used to get more yield. While the families of low hierarchy and less power used to work under the land lords. The families were broken and people in small families used to flew to towns and industrial areas where they are paid for the work done. Thus the population used to rise in the towns and cities. Poor families were forced to work for long hours and were paid less compensation. For this reason women and children used to accompany their elder family members and used to work for long hours under conditions. The growth in urban population has pressurized the water, housing, sanitation etc facilities which have had worsened the living condition in that region. There is no proper interaction in between families as the members along with their children were put into work. There were no educational facilities for children as they were no time for them to perceive. The young generation lacked the social ethics as their elders were busy in their work for most of the time. Capitalism strongly prevailed in the industrial regions. Workers safety was least concerned .The industrialization were more of production oriented and the owners made huge profits The profits increased the gap between the rich and the poor increased. No government policies were implemented as the rich used to dictate the terms.Industrial revolution has bought some positive results as the poverty has been reduced; the wages were increased in some regions. The cities were divided into their specific activities like the industrial areas, the marketing areas, the administrative areas. The working classes were ill-treated in the initial periods of industrialization. The workers... This essay discusses that education was a major concern in the industrial revolution days as people of all ages were busy in their work which lasts for 15 to 18 hours a day. Elders were educated about the mechanics of the machines and their operations. Gradually in the first quarter of the eighteenth century in England, child education was made compulsory up to 12 years. Children who were educated up to certain age were allowed part-time to work.The social responsibility was highlighted in the period of industrial revolution. This is addressing the concern of the widows, the injured soldiers and the people below poverty line. The private wealthy society was encouraged to generously participate in providing the basic needs of the needy in that period. The industrial revolution has created immense wealth for many sections which propelled them to organize aid to the people who were in distress. The increase in the communications and the accessibility to the issue regions has pushed the assistance further more. The attitudes have kept changing which resulted in a lot of nongovernmental organizations which started addressing the concerns of the poor. The social responsibility has been projected as a ritual for the wealthy and status to dissipate the surplus to the needy. The philanthropic values gradually spread to eradicate the social evils like alcoholic consumption, the abolition of slavery, improved work environment in factories and fight for the social concerns community wise.

Why do governments in less developed countries have difficulty in Essay

Why do governments in less developed countries have difficulty in restraining money supply growth in order to control inflation - Essay Example As explained, if in this particular situation, a country’s central bank opts for reduction in money supply in order to get rid of the inflation present in the economy, it will lower the gross domestic product even more and only strengthen the stagnation present in the economy even more. This situation, if continued as a long term policy, will lead to demand pull inflation in the long run. This is because on one hand the national output will be at a low level and on the other, due to a high population growth ate in these less developed economies, soon the aggregate demand will rise to a staggering level which, if tamed through a further reduction of money supply, will lead to a stagnation inflation spiral. (Chandavarkar, 1996, 9) Another problem courting these less developed economies is high rate of unemployment. Now a reduction in money supply, as explained above will discourage investment and thereby lower the level of output. As usual a lower level of output is also associated with a low level of employment. So this policy in course of time will make substantial addition to the pull of unemployed laborers of the less developed economy. The less developed economies have to bear with a certain level of inflation in order to experience growth and thereby ensure employment. Therefore, if a reduction in money supply is taken by the central bank as a policy to tame inflation in such economies it will only lead to long run aggravation of other economic maladies. (Lipsey and Harbury, 1992, 252) Furthermore, the less developed economies are typically characterized with black marketers who manage to bluff the government and thereby run a parallel economy. In such an economy, often inflation is caused by unethical storage of goods with a view to inflate the price artificially and hence reap the profit. In such cases

Effects Of Noise In A Data Communication

Effects Of Noise In A Data Communication This report will look into different types of noise that are associated with Unshielded Twisted Pair and Radio Waves. The noise that affects these transmission mediums such as thermal noise, crosstalk, multipath interference, intermodulation noise and impulse noise will be explored and the damages that it can cause to data being transmitted will be explained. I will also discuss the different modulation techniques and technologies that can be used to try and reduce the effect of the noise and reduce the risk of data loss through transmission. Introduction In 1962 Computer Scientist Joseph Carl Robnett Licklider developed ARPANET, which connected 4 computers across America; these computers were located in University of California Los Angeles, Stanford Research Institute, University of California Santa Barbra and the University of Utah. This network was designed for the purpose of sharing sensitive military data between different locations securely. However the first attempt at sending data over the network was not successful, as the UCLA computer crashed as they attempted to log into the computer at Stanford [1]. The result of these connection problems was the creation of TCP/IP and since then networks have grown in size and data rates and transmission mediums have evolved and new technology has been introduced, Noise has also started to play a part in how networks are built, as specific techniques can be put in place to try and reduce noise. Guided Media In a communication system using guided media, the signal is sent in the form of electromagnetic waves along a physical path. This physical path is what guides the signal, and can come in the form of 4 main media types, Unshielded Twisted Pair; Shielded twisted Pair, Coaxial or Fibre-Optic cables. However each of these mediums has several different standards of cables associated with them. This report will cover Unshielded Twisted Pair and the noise that can affect it. UTP UTP first originated in the 1970s, it consists of 8 insulated copper wires, each of these copper wires has a diameter of 0.4mm to 0.8mm, and these copper wires are twisted together into pairs, so there ends up being 4 pairs of 2 wires, then all 4 pairs are wrapped in a protective plastic sheath. However UTP is susceptible to several different types of noise that can lead to signal impairment and even cause the loss of data. UTP uses Manchester Encoding UTP Noise When a data transmission is received, the received signal is often modified from the original signal that was transmitted; this modification is caused by noise. Noise is defined as additional unwanted signals that are inserted somewhere between transmission and reception [2]. There are 4 different types of noise that will be researched; these are Thermal Noise, Cross talk, and Intermodulation Noise. These sources of noise can be placed into one of two categories, internal noise or external noise. Internal Noise is caused by the used of electrical components found in all communication systems. This internal noise could be produced by changes in current or imperfections on conducting materials. External Noise can be caused by different factors, such as lighting storms, or the use of large electrical machinery. [3] Thermal Noise Thermal Noise also known as Johnston or white noise was first observed in 1926 by John B. Johnston in Bell Labs. Thermal Noise is caused by electrons that become agitated at any temperature above 0, at this stage they begin to move in random patterns and bounce off other electrons, however in theory it could be stopped completely if all the components were kept at a temperature of absolute zero which is 0 Kelvin or -273.15 °C as this would mean that all the electrons would move at their slowest meaning thermal noise would be as good as eliminated, however to try and achieve absolute zero and maintain it would be extremely difficult . [4] Thermal noise is found across all the bandwidths typically used in a communication system and currently there is no practical way to completely eliminate it, however you can use different types of modulation to lower the frequency of the signal which in turn will lower the thermal noise, so for example if you had an Ethernet system and used PAM-5 modulation which has a frequency of 125MHz and this would give you a thermal noise value of 4.801510-13 WHz-1 at room temperature, where as if MLT-3 was used, you would end up with a thermal value of 1.20037510-13WHz-1 under the same temperature conditions. [5] To work this out the equation Pn= k . T. Δ f was used, where k is Boltzmans constant, T is the temperature plus 273, in this case 18 degrees plus 273 which ends up as 291 for T, and Δ f is the frequency of 125106 Hz for PAM-5 and 31.25106 Hz for MLT-3. Cross Talk Cross talk is caused by the coupling of the copper cables magnetic and electric fields, which causes some of the signal to become lost or distorted. There are two main types of cross talk, NeXT (Near End Cross Talk) and FeXT (Far End Cross Talk), NeXT is when the coupling of magnetic and electric fields occurs near the source of the signal and FeXT is when it occurs near the receiver end. To try and prevent cross talk in UTP cables, the copper cables are twisted into pairs, the number of twists per foot/meter is defined as the twist ratio, so a cable with a higher twist ratio will be more efficient eliminating cross talk, as the twisting of the copper wires makes it harder for the coupling of cables as the loop area between the wires is reduced. However if you have a cable with a high twist ratio that means that you will be using more copper cable and the signal will have to travel a further distance to the receiver, meaning attenuation could become a factor. [6] Intermodulation Noise Intermodulation noise may be present in any communications system that sends signals at different frequencies across the same medium. Intermodulation noise produces signals that are the difference, sum or multiple of the two original frequencies. Intermodulation noise is caused by the transmission medium, transmitter and receiver not being linear systems, meaning that instead of the output matching the input, the output is different from the input. It can be caused by signal strength being too excessive for the device to handle or a problem with one of the components. An example of intermodulation Noise would be if there were two signals, 10Hz and 15Hz sharing the same transmission medium and there was intermodulation noise present, these two signals could become one signal at 35Hz. This would mean that not only have the two original signals been disrupted it could potentially disrupt a third signal if there was another 35Hz signal sent out on the medium. To overcome intermodulation noise, you can use Orthogonal Frequency-Division Multiplexing, which is explained more in the multipath interference section under unguided media. [2] Unguided Media When using Unguided Media in a communications system, the signal is sent through the air via an antenna in the form of electromagnetic waves, these waves have no specific path to follow. Unguided media used for several different communications systems like wireless, Bluetooth, infrared and satellite. Each of these systems use different types of unguided media for example satellite uses microwaves, but this report will focus on wireless and the noise that can affect the radio waves wireless uses. Wireless The first radio waves were sent by Guglielmo Marconi in Italy in 1895 and in 1899 he sent the first wireless radio signal across the English Channel [7]. Wireless works by an Omni directional antenna sending out a broadcast of radio waves, these radio waves are sent at a specific frequency depending on which standard they comply to, for example if the standard being used is 802.11n then they will be sent at 2.4GHz or 5GHz. Wireless Noise Wireless can be affected by many different things. This is because radio waves travel through air meaning it can be affected by different types of weather, like rain or snow causing scattering, or obstacles such as trees or buildings causing reflections. However it can also be affected by other devices transmitting at the same frequency causing signal loss. Multi Path Interference Multi Path interference is where a receiver receives multiple copies of the same signal, at delayed times, this mainly affects radio, as satellite or microwaves generally are line of sight so there would be no obstacles present for reflection to take place. However with radio waves it is caused by the antenna sending out broadcast signals, and these signals are then reflected between obstacles, and if these reflections arrive at the receiver it means that it will end up with several different copies of the same signal arriving at varying times, and depending on the different path lengths of the original direct signal and the reflected signals it could create a larger or smaller signal that is eventually received. Multipath Interference can cause a number of problems like data corruption, which occurs if there receiver picks up multiple different reflected signals and is unable to determine the transmission information, it can also cause signal nulling, where the reflected signals are received exactly out of phase with the original signal causing the original signal to be cancelled out. Not only can it cause data loss it can change the amplitude of the signal up or down, so if the reflected signals arrive out of phase with the original signal it will cause a drop in the signal amplitude but if they arrive in phase with the main signal the amplitude will increase. To try and reduce multipath interference a diversity solution can be used. This works by using two antennas with the same gain, that are separated from one another but within the range of the same transmitter, this means that one of the antenna receive most of the multipath interference allowing the other antenna to receive a normal signal. [8] Another way to reduce Multi Path Interference is to modulate the signal with Orthogonal Frequency-Division Multiplexing, OFDM works by splitting the signal up into 48 subcarrier signals. These 48 channels each carry a different portion of the data being sent and transmit them in parallel channels. [9] These subcarrier signals are modulated with BPSK, QPSK, 16-QAM or 64 QAM, and they have a convolution code rate of  ½, 2/3 or  ¾. The data rate of the signals is determined by the modulation used and the convolution code rate. Also there is 0.3125MHz frequency spacing between each of the subcarriers. [10] [11] OFDM also has a guard interval which means that any data arriving at the receiver will only be sampled once the signal has become stable and no more reflected signals are picked up that would cause changes to the phase or timing of the signal. Also because each subcarrier is on a different frequency any interference caused by reflected signals only affects a small percentage of the subcarriers meaning that the rest are received correctly. [9] Impulse Noise Impulse Noise is an unpredictable problem. It consists of short spikes of high amplitude or short irregular pulses, these spikes and pulses are generated from a variety of different unpredictable causes usually however they relate to some sort of electromagnetic instability for example a lighting storm or any faults present in the communications devices. Impulse noise generally affects digital signals worse than it does analogue signals, for example if voice data was sent as an analogue signal and there was occurrences of impulse noise, the voice data would still be understandable as the impulse noise would create short crackles in the data, however with a digital signal the result of impulse noise could mean that all the bits sent through the duration of the impulse noise could be lost, it can however be recovered by sampling the received digital waveform once per bit time, but it can still result in a few bits being in error. As impulse noise is unpredictable, there is no way to el iminate it, however to reduce the effects of it, Coded OFDM can be used, this is very similar to OFDM, in the way that it splits the signal into multiple subcarriers, however Coded OFDM also has forward error correction that is included with the data. Because this error correction is included with the data it means that any data lost by impulse noise can be corrected at the receiver. [12] Conclusion After researching different types of noise and how it effects data communications, it became clear that it is a factor present in all systems and cannot be completely eradicated, as it can be caused by several different external sources made my man and internal sources caused by the data communication equipment. However, different strategies, techniques and error correction systems have enabled us to limit the effect that noise can have on a system and this has enabled technology to advance, meaning the chance of losing any crucial data due to the effects of noise is sufficiently lower now that what it was years ago. Reflection Throughout this report I have gained a better grasp of different aspects of data communications, for example, noise is present in all systems as any electronic device creates noise through the movement of electrons, imperfections in conductive surfaces and fluctuations of current. I also increased my knowledge of different types of modulation, and how they work regarding changing the frequencies or sending additional data to help with error correction. I have also gained knowledge on how noise can be caused by different types of weather and how they can affect the electromagnetic field and cause detrimental effects on data communication systems. Not only did this report help me gain more knowledge on data communications, it also increased my knowledge on different aspects of physics, and how closely the two subjects are connected. I feel I completed this report to a reasonably high standard and found plenty of information available on the subject, however understanding this information was more difficult than expected as maths features highly in several of the sources I found, however this did not put me off, it simply lead me to try and comprehend the more complex maths side of the topic. Once I had completed the report I had to try and remove some parts as I had overshot the word count, this proved difficult as I felt I would be missing parts out if I removed some. Overall I would say I learned a great deal more about the complexity of noise and data communication systems.

Anne Conway’s Critique of Cartesian Dualism :: Dualism Essays

Anne Conway’s Critique of Cartesian Dualism ABSTRACT: I describe and analyze Anne Conway’s critique of Cartesian dualism. After a brief biographical introduction to Conway, I sketch some of the influences on her philosophy. I then describe her non-Cartesian view of substance. According to Conway, there is only one substance in created reality. This substance contains both matter and spirit. A purely material or spiritual substance is, she argues, an impossibility. Next, I discuss several of Conway’s arguments against Cartesian dualism. Firstly, dualism is inconsistent because dualists, while denying that concepts such as divisibility and extension are applicable to spiritual substance, nevertheless use such terms when describing the soul or spirit. They assume that soul or spirit is something particular which can be located somewhere. Secondly, she argues that dualism results in mechanism because it makes too sharp a distinction between body and soul, thus regarding the body as a mechanical machine and the soul a s something which is not integrally related to the body. Thirdly, dualism cannot account for the interaction between mind and body. The two substances of which a dualist speaks are defined on the basis of the exclusion of characteristics. But the two things which have nothing in common cannot influence each other causally. 1. Introduction During his lifetime and in the centuries following, the dualism and mechanism of Descartes' philosophy gave rise to a great number of objections and discussions. In this article, I would like to consider a response to Descartes' views which is somewhat less well-known than others, that of Anne Conway. Conway's reaction to Descartes is interesting because she speaks from out of a metaphysical tradition different from those of many other philosophers who discussed his ideas. (1) In addition, she makes use of a pre-modern, non-abstract idea of spirit, a conceptualisation of spirit which has been lost or sidelined in the philosophical tradition after Descartes. On the basis of an entirely different ontology of matter and spirit from that of Descartes, Conway questions the presuppositions of dualism as well as its abstract view of spiritual substance. In this paper, I will begin with a short biographical sketch of Conway and a survey of some of the main influences on her thought. I will then briefly describe her philosophical system. I will then discuss her critique of Descartes' dualism. Finally, I will consider the question of how her views can be of value to us today.

Task: Prepare a case study of your TP group. Your report should include (250-300 words): . Information about the students’ backgrounds (approximate ages, nationalities, reasons for learning English, previous English learning experience) b. The students’ learning styles (what they like/dislike in lessons, t he things they find easy/difficult, how they like to learn) c. What YOU have noticed in their classroom behaviour (degree of participation, quantity or output in different stages of the lesson, fluency/accuracy of output, similarity of level amongst the group) ————————————————- Points a, b and c of the assignment should take the form of a REPORT.You should use a formal style of language. Make use of headings and sub-headings, paragraphs, linking words, etc to organise your work. d. A paragraph (150-200) words summarising your TP students’ main strengths in grammatical and phonological areas as well as in receptive skills. e. Identify 2 areas of weakness in your students’ grammar, 1 in pronunciation and 1 in vocabulary, providing at least one example to support your observation. State why you think the students made this error and what the correct form should be. (250–300 words) Point e can be put into boxes and bullet points can be used.Remember to include specific examples. Grammatical Weaknesses| Incorrect word order * I work also on Saturdays (I also work) * I went often home (home by bus)Reason: In German, the verb is usually the second idea in the sentence and students have transferred this rule to English. | f. Select 2 specific language focused activities (100-200 words) from published materials (not your course book) to focus on areas of weakness you identified: * 1 exercise/task focusing on grammatical areas of weakness AND * 1 exercise/task on phonological areas of weakness OR 1 exercise/task on the lexical weakness. For EACH activity: ) state the aim of the activity (i. e. by the end of this task, students should be better able to accurately use/discriminate between †¦Ã¢â‚¬ ¦ ) 2) state briefly why you think the activity would be suitable for your students. (Remember to link this to your weaknesses and your profil e of the students. ) 3) State where it comes from (Book, Author, Pg no. , Exercise no. ) and attach a referenced a copy of the activity Collecting your data: You will want to interview them so that you can note any good or weaker examples of language used. You might want to tape the interview so that you can identify language later.You could also get students to write something for you spontaneously e. g. a letter to a friend inviting them to spend the summer with them. You could also give them a reading and listening to do. You can further make use of the time before lessons start or during the breaks to chat to your students and find out the information you need. You should continue to make notes during TP classes. It is not necessary for you to personally interview all members of the class; you can interview 2 or 3 students and then share your findings with the other teachers in your TP group.You can also make generalisations on the basis of 2 or 3 students. Suggesting specific l anguage focused activities: There are an abundance of activities in different books and on the publisher’s websites too.
