Steps and methods to becoming a good skilled teacher. A critical Essay

Steps and methods to becoming a good skilled teacher. A critical analysis - Essay Example Some states also require at least Master’s degree to become a teacher. Although acquiring a higher degree is just the first step towards teaching. It is not the skill of the teacher but a necessity of the profession. In the same way, it is necessary to have complete knowledge about the subject a teacher is teaching, but just attaining knowledge does not make an outstanding teacher. There is a need to get the idea and the tact to convey that idea (Capel, Leask, & Turner, 2005). For Example, if a teacher, while teaching about printers, uses the terms Dot-Matrix and Ink-jet without telling the difference between them, the student would learn these terms rather than understanding the basic idea. The concept to grasp here is, a qualified teacher does not give importance to the basic concepts, and however an undergraduate needs explanation about each and every part of the topic. Hence, it is not just qualification which makes you a wonderful teacher but it is the level of understand ing about the difficulties and problems of the students. The strict and harsh behavior of teachers is a negative point for their career development. The duty of a teacher is to develop love and interest in students regarding their studies rather than making it a panic and fearful part of their life. Strict and harsh behaviors lock up their questions and views in their minds. Such behaviors start killing their abilities and creativity. However, there is a need of professional distance between the educators and learners. Teacher’s training programs are helpful because it provides the inexperienced with helpful strategies about teaching along with a certificate which would help them in getting a job in some reputable institute. Teacher’s training programs provide knowledge about teaching techniques which distinct them from those teachers who have not engaged in such teaching

Personal opinion - Essay Example the World War II is considered to be a huge catastrophe worldwide and I agree with the point, but let’s consider some consequences it led to which actually were not bad but even good, for example, in American society. First of all, national wealth increased, and, feeling the advent of better life, people reacted accordingly. Young people started getting married, which led to baby boom and the divorce statistics decrease; in addition, a nuclear family began being an object of imitation, and it originated the fashion of the â€Å"American dream† way of life. But the situation was not so perfect like it seemed, because on a background of American prosperity there was a Cold War situation. Stalin’s extension of communism through Europe and Eastern countries threatened to increase US power in world political arena. Cold War caused huge changes in American people’s mentality. Government’s politics of making communists the biggest enemy possible made peopl e scared of another nuclear war: they were convinced that the threat of Soviet invasion and communists’ occupation would fade the society. So the anti-communists information was widespread everywhere, and American culture acquired another feature of eternal national enemy from without existence, which lately led to the War on Terror emergence. Even though the pattern of the American Way of life was developing sweepingly, it was not available for all segments of society, racial discrimination still existed. And black people understood that the time for changes had come, so massive protest actions stirred up the entire country. Under the Martin Luther King’s leadership black people achieved recognition of their rights, which in fact was the impetus of great liberal changes in the American society. Lately, when American society was totally outraged with Lyndon Johnson’s support of the Vietnam Civil War American youth initiated protests; in addition, young people, w ho had returned from the war, definitely were

Agency Factors Essay Example for Free

Agency Factors Essay Foster parents are in a tough position. On the one hand they are expected to welcome unfamiliar children into their homes, invest in them emotionally and physically, and help them through a difficult time. On the other hand, this intense investment is supposed to be temporary. When the placement ends, foster parents are expected to disengage in a way that is helpful to the child and everyone else involved. In the hustle and bustle of a placement move, whether the child is going home or moving somewhere else, foster parents feelings of loss are often not given adequate attention. Agency Factors In 1989, Lois Urquhart conducted a study to determine whether foster parents experiences of separation and loss affected their decision to continue fostering children. She surveyed 376 foster homes, 275 of which were licensed and open to children, and 101 of which had been previously-licensed but had closed within the past three years. She found that both groups of families expressed love and affection for their foster children and sadness at their loss. The two groups also felt similar levels of anxiety and uncertainty regarding foster care placements. Urquhart found that although open home respondents more often knew how long a placement would be, both groups rarely knew from the outset a childs length of stay in their homes (p. 203). Urquhart did find two key differences between open and closed foster homes. The first emerged when she asked foster parents how well their agency prepared them for the separation and the grief they would feel at the end of a placement. While 36 percent of foster parents from open homes felt they had been taught skills for coping with a childs removal; only 19 percent of closed homes felt they had been adequately prepared. The other significant difference between open and closed homes had to do with the degree to which they felt their agency supported them before, during, and after separation. Foster parents from open homes felt they were better supported by their agency in every category assessed. Parents from open homes were also provided with information about and contact with former foster children more often than were parents from closed homes. Urquhart concludes that foster parents who are unprepared or unsupported for the separation and loss experience can be considered foster parents at risk of leaving foster care (p. 206). Emotional Factors To continue on in their work after the end of a placement, foster parents need to resolve their grief. One step in this process-expressing the pain associated with the loss-can be especially difficult for some foster parents. In When Foster Children Leave: Helping Foster Parents to Grieve, Susan Edelstein (1981) identifies four obstacles that prevent people from expressing grief over a loss. Foster parents can run up against any or all of these. First, grieving is difficult when the relationship to the lost person was ambivalent or hostile. Foster parents may experience mixed feelings about foster children, especially those who are prone to act out. A second barrier to fully expressing feelings of loss when a child leaves the foster home is the number of other demands placed on foster parents. Usually, there are other foster and biological children still in the home. Foster parents must continue to attend to these children, leaving little opportunity to express themselves. Expectations can be another barrier. It may be an unspoken expectation that foster parents should not get too attached to the children in their homes. Foster parents who express feelings of loss may be considered weak by their agency or other foster parents; they may even have their ability to foster questioned. The final barrier has to do with differences in individual personalities. Some people have a need to always appear confident and independent, and grieving makes them uncomfortable; they view the vulnerability that is part of grief as a sign of weakness. For suggestions for supportingand retainingfoster families, see Support at the End of Placement. References Edelstein, S. (1981). When foster children leave: Helping foster parents to grieve. Child Welfare, 60(7), 467-473. Urquhart, L. (1989). Separation and loss: Assessing the impacts on foster parent retention. Child and Adolescent Social Work, 6(3), 193-209. (c) 1997 Jordan Institute for Families Helping a Child Through a Permanent Separation 1. Help the child face reality. The pain needs to be acknowledged and the grieving process allowed. 2. Encourage the child to express feelings. There can be expressions of reasons for the separation without condemning parents. 3. Tell the truth. You can emphasize that his parents were not able to take care of him without saying, Your mother is an alcoholic. Also, try to deal with the fantasy that children often have that the parents will return. The permanency of the loss needs to be realized. 4. Encourage the child to ask questions. Again, be as truthful in your responses as you can without hurting the child. Never lie to the child, even to spare some pain. 5. Process with the child why the losses occurred. Ask about his ideas of why he has made the moves he has and experienced these losses. 6. Spend time with the child. Any child who has experienced separation feels rejection and guilt. This can interfere with his sense of trust in others and himself. By spending time and talking with the child, a new, trusting relationship can be built between the worker and child during preparation. This, in turn, can lead to other healthy relationships. 7. Encourage information about the past. A childs identity is partly a result of having a past that is continuous. To achieve this continuity, various techniques, such as the Life Book, are valuable. Social, cultural, and developmental information needs to be included in the book and made available to the child. 8. Understand your own feelings. It is difficult to share the pain of separation and to be the one who helps the child face realitysuch as the fact that he may never see his biological or foster parents again. Often, the worker would prefer to avoid the pain and angry feelings. However, if these feelings are not dealt with now, they will recur and may jeopardize placement.

Artificial Intelligence and Robotics Applications

Artificial Intelligence and Robotics Applications I. Introduction Artificial intelligence  (AI) is the  intelligence  of machines and the branch of  computer science  that aims to create it. Textbooks define the field as the study and design of  intelligent agents,[1]  where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success.[2]  John McCarthy, who coined the term in 1956,[3]  defines it as the science and engineering of making intelligent machines. The field was founded on the claim that a central property of humans, intelligence-the  sapience  of  Homo sapiens-can be so precisely described that it can be simulated by a machine.  This raises philosophical issues about the nature of the  mind  and limits of scientific  hubris, issues which have been addressed by  myth,  fiction  and  philosophy  since antiquity.[6]  Artificial intelligence has been the subject of optimism,[7]but has also suffered setbacks[8]  and, today, has become an e ssential part of the technology industry, providing the heavy lifting for many of the most difficult problems in computer science. AI research is highly technical and specialized, deeply divided into subfields that often fail to communicate with each other.[10]  Subfields have grown up around particular institutions, the work of individual researchers, the solution of specific problems, longstanding differences of opinion about how AI should be done and the application of widely differing tools. The central problems of AI include such traits as reasoning, knowledge, planning, learning, communication, perception and the ability to move and manipulate objects.[11]  General intelligence (or strong AI) is still a long-term goal of (some) research. AI plays a major role in the field of robotics. The word  robot  can refer to both physical robots and  virtual  software agents, but the latter are usually referred to as  bots.[3]  There is no consensus on which machines qualify as robots, but there is general agreement among experts and the public that robots tend to do some or all of the following: move around, operate a mechanical limb, sense and manipulate their environment, and exhibit intelligent behaviour, especially behaviour which mimics humans or other animals. There is conflict about whether the term can be applied to remotely operated devices, as the most common usage implies, or solely to devices which are controlled by their software without human intervention. In  South Africa,  robot  is an informal and commonly used term for a set of traffic lights. It is difficult to compare numbers of robots in different countries, since there are different definitions of what a robot is. The  International Organization for Standardization  gives a definition of robot in  ISO 8373: an automatically controlled, reprogrammable, multipurpose, manipulator programmable in three or more axes, which may be either fixed in place or mobile for use in industrial automation applications.[5]  This definition is used by the International Federation of Robotics, the  European Robotics Research Network  (EURON), and many national standards committees. The Robotics Institute of America (RIA) uses a broader definition: a robot is a re-programmable multi-functional manipulator designed to move materials, parts, tools, or specialized devices through variable programmed motions for the performance of a variety of tasks.[7]  The RIA subdivides robots into four classes: devices that manipulate objects with manual control, automated devices that manipulate objects with predetermined cycles, programmable and servo-controlled robots with continuous point-to-point trajectories, a nd robots of this last type which also acquire information from the environment and move intelligently in response. There is no one definition of robot which satisfies everyone, and many people have their own.[8]  For example,  Joseph Engelberger, a pioneer in industrial robotics, once remarked: I cant define a robot, but I know one when I see one.[9]  According to  Encyclopaedia Britannica, a robot is any automatically operated machine that replaces human effort, though it may not resemble human beings in appearance or perform functions in a humanlike manner.[10]  Merriam-Webster  describes a robot as a machine that looks like a human being and performs various complex acts (as walking or talking) of a human being, or a device that automatically performs complicated often repetitive tasks, or a mechanism guided by automatic controls. Modern robots are usually used in tightly controlled environments such as on  assembly lines  because they have difficulty responding to unexpected interference. Because of this, most humans rarely encounter robots. However,  domestic robots  for cleaning and maintenance are increasingly common in and around homes in developed countries, particularly in  Japan. Robots can also be found in the  military. II. HISTORY Mechanical or  formal reasoning  has been developed by philosophers and mathematicians since antiquity. The study of logic led directly to the invention of the  programmable digital electronic computer, based on the work of  mathematician  Alan Turing  and others. Turings  theory of computation  suggested that a machine, by shuffling symbols as simple as 0 and 1, could simulate any conceivable act of mathematical deduction.[23]  This, along with recent discoveries in  neurology,  information theory  and  cybernetics, inspired a small group of researchers to begin to seriously consider the possibility of building an electronic brain.[24] The field of AI research was founded at  a conference  on the campus of  Dartmouth College  in the summer of 1956.[25]  The attendees, including John McCarthy,  Marvin Minsky,  Allen Newell  and  Herbert Simon, became the leaders of AI research for many decades.[26]  They and their students wrote programs that were, to most people, simply astonishing:[27]  computers were solving word problems in algebra, proving logical theorems and speaking English.[28]  By the middle of the 1960s, research in the U.S. was heavily funded by the  Department of Defense[29]  and laboratories had been established around the world.[30]  AIs founders were profoundly optimistic about the future of the new field:  Herbert Simon predicted that machines will be capable, within twenty years, of doing any work a man can do[31]  and  Marvin Minsky   agreed, writing that within a generation the problem of creating artificial intelligence will substantially be solved.[32] In the early 1980s, AI research was revived by the commercial success of  expert systems,[35]  a form of AI program that simulated the knowledge and analytical skills of one or more human experts. By 1985 the market for AI had reached over a billion dollars. At the same time, Japans  fifth generation computer  project inspired the U.S and British governments to restore funding for academic research in the field.[36] Stories of artificial helpers and companions and attempts to create them have a long history but fully autonomous  machines only appeared in the 20th century. The first  digitally  operated and programmable robot, the  Unimate, was installed in 1961 to lift hot pieces of metal from a die casting machine and stack them. Today, commercial and  industrial robots  are in widespread use performing jobs more cheaply or with greater accuracy and reliability than humans. They are also employed for jobs which are too dirty, dangerous or dull to be suitable for humans. Robots are widely used in manufacturing, assembly and packing, transport, earth and space exploration, surgery, weaponry, laboratory research, and mass production of consumer and industrial goods.[4] The word  robot  was introduced to the public by Czech  writer  Karel ÄÅ'apek in his play  R.U.R. (Rossums Universal Robots), published in  1920.[16]  The play begins in a  factory  that makes artifici al people called  robots, but they are closer to the modern ideas of  androids, creatures who can be mistaken for humans. They can plainly think for themselves, though they seem happy to serve. At issue is whether the  robots  are being  exploited  and the consequences of their treatment. However, Karel ÄÅ'apek himself did not coin the word. He wrote a short letter in reference to anetymology  in the  Oxford English Dictionary  in which he named his brother, the painter and writer Josef ÄÅ'apek, as its actual originator.[16]  In an article in the Czech journal  Lidovà © noviny  in 1933, he explained that he had originally wanted to call the creatures  laboÃ…â„ ¢i  (from  Latin  labor, work). However, he did not like the word, and sought advice from his brother Josef, who suggested roboti. III. FIELDS OF ARTIFICIAL INTELLIGENCE A. Combinatorial Search Many problems in AI can be solved in theory by intelligently searching through many possible solutions:[96]  Reasoning  can be reduced to performing a search. For example, logical proof can be viewed as searching for a path that leads from  premises to   conclusions, where each step is the application of an  inference rule.[97]  Planning  algorithms search through trees of goals and sub goals, attempting to find a path to a target goal, a process called  means-ends analysis.[98]  Robotics  algorithms for moving limbs and grasping objects use  local searches  in configuration space.[67]  Many  learning  algorithms use search algorithms based on  optimization. Simple exhaustive searches[99]  are rarely sufficient for most real world problems: the  search space  (the number of places to search) quickly grows to  astronomical  numbers. The result is a search that is  too slow  or never completes. The solution, for many problems, is to use heu ristics or rules of thumb that eliminate choices that are unlikely to lead to the goal (called pruning  the  search tree).  Heuristics  supply the program with a best guess for what path the solution lies on.[100]A very different kind of search came to prominence in the 1990s, based on the mathematical theory of  optimization. For many problems, it is possible to begin the search with some form of a guess and then refine the guess incrementally until no more refinements can be made. These algorithms can be visualized as blind  hill climbing: we begin the search at a random point on the landscape, and then, by jumps or steps, we keep moving our guess uphill, until we reach the top. Other optimization algorithms are  simulated annealing,  beam search  and  random optimization.[101] Evolutionary computation  uses a form of optimization search. For example, they may begin with a population of organisms (the guesses) and then allow them to mutate and recombine,  selecting  only the fittest to survive each generation (refining the guesses). Forms of  evolutionary computation  include  swarm intelligence  algorithms (such as  ant colony  or  particle swarm optimization) and  evolutionary algorithms B. Neural Network A neural network is an interconnected group of nodes, akin to the vast network of  neurons  in the  human brain. The study of  artificial neural networks[127]  began in the decade before the field AI research was founded, in the work of  Walter Pitts  and  Warren McCullough. Other important early researchers were  Frank Rosenblatt, who invented the  perception  and  Paulwerbos who developed the  back propagation  algorithm.[134]The main categories of networks are acyclic or  feed forward neural networks  (where the signal passes in only one direction) and  recurrent neural networks  (which allow feedback). Among the most popular feed forward networks are  perceptions,  multi-layer perceptions  and  radial basis networks.[135]  Among recurrent networks, the most famous is the  Hopfield net, a form of attractor network, which was first described by  John Hopfield  in 1982.  Neural networks can be applied to the problem of  intelli gent control(for robotics) or  learning, using such techniques as  Hebbian learning  and  competitive learning.[137]Jeff Hawkins  argues that research in neural networks has stalled because it has failed to model the essential properties of the  neocortex, and has suggested a model (Hierarchical Temporal Memory) that is based on neurological research. C. Approaches There is no established unifying theory or  paradigm  that guides AI research. Researchers disagree about many issues.[76]  A few of the most long standing questions that have remained unanswered are these: should artificial intelligence simulate natural intelligence, by studying psychology  or  neurology? Or is human biology as irrelevant to AI research as bird biology is to  aeronautical engineering?  Can intelligent behavior be described using simple, elegant principles (such as  logic  or  optimization)? Or does it necessarily require solving a large number of completely unrelated problems?[78]  Can intelligence be reproduced using high-level symbols, similar to words and ideas? Or does it require sub-symbolic processing?[79] D. General Intelligence Main articles:  Strong AI  and  AI-complete Most researchers hope that their work will eventually be incorporated into a machine with  general Intelligence (known as  strong AI),combining all the skills above and exceeding human abilities at most or all of them.[12]  A few believe that  anthropomorphic  features like  artificial consciousness  or an artificial brain  may be required for such a project.[74]  Eliezer Yudkowsky  has argued for the importance of  friendly artificial intelligence, to mitigate the risks of an uncontrolled intelligence explosion. The Singularity Institute for Artificial Intelligence  is dedicated to creating such an AI. Many of the problems above are considered  AI-complete: to solve one problem, you must solve them all. For example, even a straightforward, specific task like  machine translation  requires that the machine follow the authors argument (reason), know what is being talked about (knowledge), and faithfully re produce the authors intention (social intelligence).  Machine translation, therefore, is believed to be AI-complete: it may require  strong AI  to be done as well as humans can do it.[75] E. Planning Intelligent agents must be able to set goals and achieve them.[56]  They need a way to visualize the future (they must have a representation of the state of the world and be able to make predictions about how their actions will change it) and be able to make choices that maximize the utility  (or value) of the available choices.[57]In classical planning problems, the agent can assume that it is the only thing acting on the world and it can be certain what the consequences of its actions may be.[58]  However, if this is not true, it must periodically check if the world matches its predictions and it must change its plan as this becomes necessary, requiring the agent to reason under uncertainty.[59]Multi-agent planning  uses the  cooperation  and  competition  of many agents to achieve a given goal.  Emergent behavior  such as this is used bye volutionary algorithms  and  swarm intelligence. F. Learning Machine learning  has been central to AI research from the beginning.[62]  Unsupervised learning  is the ability to find patterns in a stream of input.  Supervised learning  includes both  classification  and numerical   regression. Classification is used to determine what category something belongs in, after seeing a number of examples of things from several categories. Regression takes a set of numerical input/output examples and attempts to discover a continuous function that would generate the outputs from the inputs. In  reinforcement learning[63]  the agent is rewarded for good responses and punished for bad ones. These can be analyzed in terms of  decision theory, using concepts like  utility. The mathematical analysis of machine learning algorithms and their performance is a branch of  theoretical computer science  known as computational learning theory G. Motion And Manipulation The field of  robotics[66]  is closely related to AI. Intelligence is required for robots to be able to handle such tasks as object manipulation[67]  and  navigation, with sub-problems of  localization  (knowing where you are),  mapping  (learning what is around you) and  motion planning  (figuring out how to get there). H. Knowledge Representation Knowledge representation  and  knowledge engineering  are central to AI research. Many of the problems machines are expected to solve will require extensive knowledge about the world. Among the things that AI needs to represent are: objects, properties, categories and relations between objects;[45]  situations, events, states and time;[46]  causes and effects;[47]  knowledge about knowledge (what we know about what other people know);  and many other, less well researched domains. A complete representation of what exists is an  ontology  (borrowing a word from traditional  philosophy), of which the most general are called  upper ontologies. I. Natural Language Processing Natural language processing[64]  gives machines the ability to read and understand the languages that humans speak. Many researchers hope that a sufficiently powerful natural language processing system would be able to acquire knowledge on its own, by reading the existing text available over the internet. Some straightforward applications of natural language processing include  information retrieval  (or  text mining) and  machine translation. IV. APPLICATIONS OF ROBOTS Robotics has been of interest to mankind for over one hundred years. However our perception of robots has been influenced by the media and Hollywood. One may ask what robotics is about? In my eyes, a robots characteristics change depending on the environment it operates in. Some of these are: A. Outer Space   Manipulative arms that are controlled by a human are used to unload the docking bay of space shuttles to launch satellites or to construct a space station B. The Intelligent Home   Automated systems can now monitor home security, environmental conditions and energy usage. Door and windows can be opened automatically and appliances such as lighting and air conditioning can be pre programmed to activate. This assists occupants irrespective of their state of mobility. C. Exploration   Robots can visit environments that are harmful to humans. An example is monitoring the environment inside a volcano or exploring our deepest oceans. NASA has used robotic probes for planetary exploration since the early sixties. D. Military Robots   Airborne robot drones are used for surveillance in todays modern army. In the future automated aircraft and vehicles could be used to carry fuel and ammunition or clear minefields E. Farms   Automated harvesters can cut and gather crops. Robotic dairies are available allowing operators to feed and milk their cows remotely. F. The Car Industry Robotic arms that are able to perform multiple tasks are used in the car manufacturing process. They perform tasks such as welding, cutting, lifting, sorting and bending. Similar applications but on a smaller scale are now being planned for the food processing industry in particular the trimming, cutting and processing of various meats such as fish, lamb, beef. G. Hospitals   Under development is a robotic suit that will enable nurses to lift patients without damaging their backs. Scientists in Japan have developed a power-assisted suit which will give nurses the extra muscle they need to lift their patients- and avoid back injuries. The suit was designed by Keijiro Yamamoto, a professor in the welfare-systems engineering department at Kanagawa Institute of Technology outside Tokyo. It will allow caregivers to easily lift bed-ridden patients on and off beds. In its current state the suit has an aluminium exoskeleton and a tangle of wires and compressed-air lines trailing from it. Its advantage lies in the huge impact it could have for nurses. In Japan, the population aged 14 and under has declined 7% over the past five years to 18.3 million this year. Providing care for a growing elderly generation poses a major challenge to the government. Robotics may be the solution. Research institutions and companies in Japan have been trying to create robotic nurses to substitute for humans. Yamamoto has taken another approach and has decided to create a device designed to help human nurses. In tests, a nurse weighing 64 kilograms was able to lift and carry a patient weighing 70 kilograms. The suit is attached to the wearers back with straps and belts. Sensors are placed on the wearers muscles to measure strength. These send the data back to a microcomputer, which calculates how much more power is needed to complete the lift effortlessly. The computer, in turn, powers a chain of actuators or inflatable cuffs that are attached to the suit and worn under the elbows, lower back and knees. As the wearer lifts a patient, compressed air is pushed into the cuffs, applying extra force to the arms, back and legs. The degree of air pressure is automatically adjusted according to how much the muscles are flexed. A distinct advantage of this system is that it assists the wearers knees, being only one of its kind to do so. A number of hurdles are still faced by Yamamoto. The suit is unwieldy, the wearer cant climb stairs and turning is awkward. The design weight of the suit should be less than 10 kilograms for comfortable use. The latest prototype weighs 15 kilograms. Making it lighter is technically possible by using smaller and lighter actuators. The prototype has cost less than  ¥1 million ($8,400) to develop. But earlier versions developed by Yamamoto over the past 10 years cost upwards of  ¥20 million in government development grants. H. Disaster Areas   Surveillance robots fitted with advanced sensing and imaging equipment can operate in hazardous environments such as urban setting damaged by earthquakes by scanning walls, floors and ceilings for structural integrity. I. Entertainment   Interactive robots that exhibit behaviours and learning ability. SONY has one such robot which moves freely, plays with a ball and can respond to verbal instructions. V. ADVANTAGES OF ROBOTS A. Business Benefits Robots have the ability to consistently produce high-quality products and to precisely perform tasks. Since they never tire and can work nonstop without breaks, robots are able to produce more quality goods or execute commands quicker than their human counterparts B. Management Benefits Robot employees never call in sick, never waste time and rarely require preparation time before working. With robots, a manager never has to worry about high employee turnover or unfilled positions C. Employee Benefits Robots can do the work that no one else wants to do-the mundane, dangerous, and repetitive jobs. Common Misconception about Robots : Introducing robots into a work environment does not necessarily mean the elimination of jobs. With the addition of robots comes the need for highly-skilled, human workers. D. Consumer Benefits Robots produce high quality goods Since robots produce so many quality goods in a shorter amount of time than humans, we reap the benefits of cheaper goods. Since the products are produced more quickly, this significantly reduces the amount of time that we are forced to wait for products to come to the marketplace VI. SHORTCOMINGS Fears and concerns about robots have been repeatedly expressed in a wide range of books and films. A common theme is the development of a master race of conscious and highly intelligent robots, motivated to take over or destroy the human race. (See  The Terminator,  Runaway,  Blade Runner,  Robocop,  the Replicators in  Stargate,  the Cylons in  Battlestar Galactica,  The Matrix,  THX-1138, and  I, Robot.) Some fictional robots are programmed to kill and destroy; others gain superhuman intelligence and abilities by upgrading their own software and hardware. Examples of popular media where the robot becomes evil are  2001: A Space Odyssey,  Red Planet, Another common theme is the reaction, sometimes called the uncanny valley, of unease and even revulsion at the sight of robots that mimic humans too closely.[99]  Frankenstein  (1818), often called the first science fiction novel, has become synonymous with the theme of a robot or monster advancing beyond its creator. In the TV show, Futurama, the robots are portrayed as humanoid figures that live alongside humans, not as robotic butlers. They still work in industry, but these robots carry out daily lives. Manuel De Landa  has noted that smart missiles and autonomous bombs equipped with artificial perception can be considered robots, and they make some of their decisions autonomously. He believes this represents an important and dangerous trend in which humans are handing over important decisions to machines.[100] Marauding robots may have entertainment value, but unsafe use of robots constitutes an actual danger. A heavy industrial robot with powerful actuators and unpredictably complex behavior can cause harm, for instance by stepping on a humans foot or falling on a human. Most industrial robots operate inside a security fence which separates them from human workers, but not all. Two robot-caused deaths are those of Robert Williams and  Kenji Urada. Robert Williams was struck by a robotic arm at a casting plant in  Flat Rock, Michigan  on January 25, 1979.[101]  37-year-old  Kenji Urada, a Japanese factory worker, was killed in 1981; Urada was performing routine maintenance on the robot, but neglected to shut it down properly, and was accidentally pushed into a  grinding machine. VII. CONCLUSIONS If the current developments are to be believed then the next wave of robots will have a supernatural resemblance with humans with the help of AI. The Indian automotive industry has finally awaken to the fact that robotics is not just about saving labour, but it also helps companies significantly to step up productivity and quality to meet the demands of international competition. Industrial robots can be involved in production industry because of its less time consumption, accuracy of work, and less labour. As globalization accelerates, robotics is increasingly vital to maintain the health of the industrial sector and keep manufacturing jobs at home. Now more than ever, the need to stay competitive is a driver for investing in robotics. Companies in all over the world are often faced with difficult choices: Do they send their manufacturing to low-cost producers overseas? Or, do they invest in robotics to continue making products here? We conclude that more companies are realizing tha t robotics is the better option.

The Effectiveness of Treatment for Anorexia Nervosa and Bulimia Essay

Anorexia nervosa and bulimia are eating disorders that severely affect both men and women around the world. The cause of the eating disorder usually derives from psychological, biological and social forces. Eating disorders have become an epidemic in American society, twenty-four million people of all ages and genders suffer from an eating disorder in the U.S. (National Association of Anorexia Nervosa and Associated Disorders.\, 2011). There are many ways to address and treat an eating disorder. There have been multiple studies conducted to test the effectiveness of different types of treatment. My central research question analyzes the relationship between the continuation of the eating disorder with the presence of intervention or some form of therapy. The use of therapy will take place as the dependent variable due to its relationship toward the termination of the eating disorder. There are social processes involved in the ceasing of an eating disorder or alleviating the symptoms of the disorder as shown through group therapy (Mclorb and Taub, 1987). I will review different sociological literature that approaches the relation between the continuations of eating disorders with the presence of treatment. In the observational case study by Mclorb and Taub, (1987), they interviewed participants of a group therapy session involving a group of fifteen young women battling a range of eating disorders. The therapy sessions were modeled after alcoholics anonymous meetings. The subjects would meet weekly in search of support, this was a form of therapy that allowed the subjects to involve or remove themselves at any point in time. The main purpose was to seek a sense of support from people dealing with the same issue. They discusse... ... IL: National Association of Anorexia Nervosa & Associated Disorders.

The Right Stuff :: Essays Papers

The Right Stuff In the past couple of semesters the topic of expatriates has come up a lot. I’m beginning to see that’s it’s an important issues since we now live in a global market. I do believe that if your successful in your career the likely hood of receiving an expatriate assignment is high. The Houston Business Journal conducted a survey of one hundred companies and sixty percent predict that the expatriate population will increase, while twenty-five percent said it will stay the same (HBJ, June 98). Since the probability is high that I will be asked to go to another country, I’ve had to do some serious reflecting. Would I be a good expatriate employee? There are qualities one must have in order to become a successful expatriate. According to Jeff Freeburg a consultant for H.R. International certain qualities one should have are motivation, receptiveness, Patience, sense of humor, initiative, confidence, dependable, savvy, persistent and decisive (Freeburg 99 ). I feel that I do have most of these qualities but is that enough? I am fortunate that I’m able to speak Spanish fluently, I can also read and write it. It was easy for me to pick up different languages since I’m a first generation U.S. citizen; I grew up with my family members speaking both languages to me. Because of that exposure I have the desire to learn other languages, I can read French and hope to learn Italian and Japanese if time allows me to. Even though I speak a different language I have never left the states to visit other countries either for personal or business reasons. Shannon Roxborough author of The Guide to International Work Success lists other important things one must do before venturing abroad. An expatriate should learn some history in order to deal better with the cultural differences. Learn the business culture, as we have read in the case study of Buckeye Glass Company in China, we have learned the importance other cultures place on building a personal relationship that goes beyond the normal business relations in this county. Learn how to negotiate, American business professional must learn how to conduct proper negotiations in other countries, not every one rushes to the table to hammer out an agreement. Also as we’ve read other countries use tactics such as long pauses or touching during negotiations that seem strange to us but are perfectly normal for them.

Princess Regional Trucking Company Essay

Princess Regional Trucking Company has been approached by a client with an opportunity that would require 120 trailers which is about 20 more than we currently own. We are not sure how long the relationship with this customer will last but this deal has the potential for considerable growth. I have a great deal of information for you regarding lease options that Princess Regional Trucking Company may want to consider before going forward with this deal. The first type of lease to consider is the direct financing lease. This lease is used by lessors in capital leases if the collections of minimum lease payments are guaranteed and the amounts of unrefundable costs are known in advance. In this type of lease the bank will buy new trucks and lease them to us instead of Princess Regional Trucking Company borrowing the money to purchase the trucks. The direct financing approach is the same as a loan. In order to arrange this type of lease we must show that the monthly payment will be met every month on time. This can be done by putting up assets to cover the payments just in case we cannot lease what is secured by the direct lease. Eliminating any question or doubt about the ability to cover the lease is the ultimate goal. If you would prefer to go with the Capital lease option then it must meet one of the four criteria according to FASB ASC 840-10-25-1. There has to be a transfer of ownership to the lessee by the end of the lease term, the lease contains a bargain purchase option, the lease term is equal to 75% or more of the estimated economic life of the leased property, or the present value at the beginning of the lease term of the minimum lease payments, equals or exceeds 90% of the excess of the fair value of the leased property. If any of the four criteria is met and also meets both of these criteria’s in that the lease payments have to be reasonable and the costs to be incurred are also predictable the lease is considered to be either direct financing or sales-type (http://highered.mcgraw-hill.com/sites/dl/free/0073526878/588542/Codification_Updates.pdf) The next type of lease to be addressed is a sales-type lease. Just like the capital lease there are for criteria that must be met. If the manufacture or dealer risks profit or loss then this would be a sales-type lease. This would mean that the seller would keep the assets in their inventory while the manufacturer or dealer are still earning profit or taking a loss. Under FASB ASC 840-30-35-22 the lessor must amortize the unearned income on a sales-type lease to income over the lease term to produce a constant periodic rate of return on the net investment in the lease.(http://highered.mcgraw-hill.com/sites/dl/free/0073526878/588542/Codification_Updates.pdf) Since the important part of a sales-type lease is the sale the initial direct costs of getting the lease is written off when the sale is recorded at the beginning of the lease. This would be noted on the income statement as a selling expense. The final type of lease option would be an operating lease. This type of lease allows use of an asset but does not transfer ownership of the asset. The assets are expected to be returned at the end of the lease agreement. This lease would give Princess the sole right to use the asset however the lessee would retain all risks and rewards of ownership. It would be shown as a rental expense on the balance sheet. It is considered an asset for us and gets depreciated like any other asset. This type of lease is usually short term but it can be cancelled if needed. Thank you for taking the time to review these three different types of leases for the additional trucks we need to satisfy our new customer. Since we are not certain the time frame of this relationship I would like to suggest going with the operating lease since it is more like a rental agreement.
