Football and Soccer Compare and Contrast
Football and Soccer Compare and Contrast. Football and soccer have never been really compared before, probably because alot of people think they dont have many similarities. But they actually have alot more in common that people think they do. Having played both sports myself i can tell you that they are very different in varius ways, but also very alike. It depends in what aspects you look at it that you can see differences or similarites. Off field soccer and football share different backgrounds. On field comparisons are never talked about but they actually have somre similarities. Yes football is more of a contact sport, and soccer more of a technique sport. But football does have technique as well, and soccer contact. On the field, both teams rely on team play to move up the field and try to score on the opposing team. Both sports have a total of 22 players on the field, 11 on each team, and passing the ball to teamates is key. In both sports the offensive players take most of the glory and the spotlight, but its know that without a good defense, its hard to win. You can score all the points you want but if they score more points on you then your still losing. Scoring is very different though. On football each time you score is called a touchdown and its given 6 points plus and extra point to try to make it 7. Soccer scoring its only 1 point and its not called touchdown but its called gol. The game of football has alot more breaks during it, and it has 4 quarters. During each play you have small breaks, plus alot of timeouts and tv comercial breaks. Soccer is a non-stop sport with only 2 halfs and no breaks during each half, just the 30 minute halftime break. One of the main differences on both these sports in my mind is that football is only a sport played in the United States, while soccer is a worldwide know sport. Soccer means alot in many countries all over the world, and theres tournaments that bring every teams all over the world together. Football's major event is held here in the United States and it only it involves the one country. United States has soccer, but its one of their least successful sports economacly and physically. It has faild to reach the fan base they wanted, and the MLS (soccer league) was close to be being shut own due to lack of fans and lack of income. Soccer is like a religion in many countries all over the world and it means everything to its fans. Where im from, Argentina, soccer is bigger than anything. Alot of people take soccer even more serious than their jobs. Sometimes a little to serious. There has been a lot of soccer related accidents in Argentina and many other parts of the world. Many of the ac cidents occur during games in the stands. Soccer rivalries are very big in Argentina. Sometimes they seperate towns. Just like gangs here in United States, soccer fans fight for respect and hate towards the other team, a lot of times ending in deaths. Other incidents occur off the field. A good example to show how serious fans take the game, is the incident that occur after a World Cup, when a colombian player scored an own goal during an important game, and he was assasinated a few days later. Things like that usually never happen here in the United States. Not to say that fans are no passionate about football, but its a different type of passion. The United States understands how important soccer is worldwide, and they have tried to make soccer bigger here in the United Sates, but have failed several times. They have tried to publish soccer more by advertising and by trying to bring famous players all over the world to play here in the United States. Living here in the US, i saw that football was the major sport here. But there are alot of competing sports like basketball and baseball, and there is also college sports, which are also very big here. In Argentina, there are of course many other sports, but none come close to soccer. As a little kid, i never knew of any other sport than soccer. Every little kid growing up wants to be a soccer player when their older. And that dosn't sound like a problem, but in my opinion it is. Alot of kids growing up have ââ¬Å"dream jobsâ⬠. Some are sports realted some are not. A lot of kids dream of being doctors, lawyers, firemans and of course start athleets. But in Argentina, most of the kids wanna be the only thing they knew growing up, a soccer player. And with most of those kids not reaching that dream, it leaves a lot of confused kids. So like most people think, there are many differences overall between football and soccer. But there are more similarities than people think there are. Maybe in the future wih the growth of soccer in the United States, we will have even more things in common. And maybe the passion for soccer here in US will one day be as big as it is in the rest of the world, but hopefullt without all the violence.

Advantages and Disadvantages of International Trade Essay
Introduction Textile industries are significant segment, which distinguished countryââ¬â¢s success by which nations establish to accomplish its respective aimed goal. International trade of textile is the exchange of textile between countries. The trade of textile contributes to the economy of the world. In which the prices of textiles, and their supply and demand, that affect and get affected by global events. Trading textiles globally provide countries and consumer the opportunity to expose to services and goods not available in their own country. Almost every quality of textile can be found in international trade. A textile that can be sold in the global market is called as an exporter, and textile which can be bought from the global market is called as an importer. Export and import are accounted for current account of countryââ¬â¢s in the balance of payment When there is no trade between the rest of the world and China Exporting means manufacturing goods or services within the country and trading or selling them to another country. Whereas, importing means the acquisition and sale of services or good from acquired from another country and selling those acquired good within the country. If there is no trade activity between China and the rest of the world, i.e. import and export ofà product or services, then in this case there will be no importer or exporter of textile as there is no such activities between these two countries. Since, the prices of textile in china are lower than the textile price, which are offered in the rest of the world. China has capacity for improvement as its improving living style, bringing increased demand in both quality and quantity of textile product, and its manufacturing process is cheaper as compared to the rest of the world. Also, there will be no effect over the price of textile in China and the rest of the world. Because both of them are selling the textile domes tically to their local consumers. When there is a trade between the rest of the world and China When the trade is allowed to take place freely between the two countries, then import and export activities take place. China and the rest of the world will be able to sell its textile globally enabling them to import and export textile. The textile industry serves as a pillar of Chinaââ¬â¢s economy due to the factor endowment and market scale. The competitive advantage of Chinese textile industry as compared to the world is their cheap labor cost and their technology. Chinaââ¬â¢s textile industry display obvious scale economy and possess cost effects in supplying of material, labor cost, quality of product, compatibility between down and up stream, which pay for its dynamic export competitive advantage. However, the abolition of textile quotas in 2005 is helpful for textile sector in china to win access to foreign market, and helpful in constructing the opportunity for scale expansion and industry upgrade. The second main advantage of globalization in china is due to the super iority of China in material supply. China is the world largest producer of cloth, cotton, natural fiber and yarn due to the status of her superiority in resources and agriculture. Whereas, the richness in natural fiber and growth in the chemical fiber sector brings superiority advantage for the Chinese textile industry as compared to those developed countries. Comparison of china textile industry as compared to the developed countries. Chinaââ¬â¢s textile industry is largely curtailed from comparative advantage in natural resource endowment and advantage in labor supply. Due to the integrated industrial chain and cheaper labor cost, the textile product of china is most competitive and main exports. However, the developed countriesââ¬â¢ advantage in textile lies in the R&D, brand and matured marketingà channels and abundant capital, which is the expensive resources as compared to Chinese traditional resources. As China is a major consumer and producer of textile product. It has a great potential in consumption and production opens a vast market of medium and textile, textile machinery from developed countries, which results in advance interdependence among textile industries on both sides. As the production of Chinese textile industry is comparatively lower than those of developing countries. The production process of the USA is mainly concerned with high wages of employees, high research and development cost, and excess cost of the advertisement, as compared to the cost incurred by the Chinese. The introduction of China into the global market will cause the prices of the textile to decrease because of the above factors. Thus increasing the competition in the industry and pressure exerts by the US consumer over their textile industry to lower the prices in order to remain in the market. In this way China will enjoy the benefit more than the developed nation due to its competitive advantage as other developed nations, including the USA will face loss in a form of expenditure incurred and high cost of textile as compared to China. This loss can result in a decrease of profitability or list of customers. Free trade is the best trade policy Free trade is a policy made by international markets in which government of the country does not restrict imports and export. Free trade can be exemplified by the European union and the North American Free Trade Agreement, which is created to establish open markets. However, most of the government in order to protect local employment impose protectionist policies that are intended to support them, such as subsidies to export or applying tariffs to imports. Most of the economist is in favor of free trade. Free trade improves lives of peopleââ¬â¢s. Through it each person can specialize in what they do best. Free trade promotes competition in the supply of services and goods, which results in motivates people to develop better, less expensive services and goods. Policy-makers have learned how important is freedom to trade in order to improve and increase the welfare and standard of living. According to the world trade organization, the applied tariff in the developed countries has fallen by 10% in 1980 to under 5% per day. Due to the fall of these barriers, the flow of trade hasà increased dramatically. The removal of trade barriers, particularly in some fast moving economies enables more than 500 million people to lift themselves up from the poverty, including 400 million in china and million of people in india. Free trade hard to achieve Independent nations negotiate trade agreements, which are in their own interest and value in mind. Other than maximizing the global output level, there are values and interest among the independent nations. Following are the reasons why it is hard to achieve the free trade. International trade required more resources to distribute, as delivering products on the other side of the world has an environmental impact because it uses fossil fuel in delivery from overseas, as compared to local delivery. Economic disruption will also produce by the shortage of fuel energy and increase in fuel price as it is a finite resource that is being depleted. The influence of foreign firm will be made in developing countries, in subsidizing local corporation offers accusation of Protection by free trade advocates, while businesses to foreign corporation are portrayed as a mere balanced incentive. Free trades are opportunity to dominate the market by the developed countries, only developed countries can take advantage of it. But developing nations, it undermines their relative advantage. Developing countries solely focus on elementary and simple industries, because their comparative advantage is always a cheap labor. They are concerned that they may keep suffering at the root of international division of labor if they bear by the static principle.

How Does Paid Employment Affect The Identity Essay - 4
How Does Paid Employment Affect The Identity - Essay Example This research will begin with the statement that in order to have paid employment exert friendly influences on oneââ¬â¢s identity, it consequently becomes highly important to learn all the critical ways to thrive in a career in a very positive and professional manner. This remains a reality that employment heavily interferes with oneââ¬â¢s identity, self-esteem, and psychological satisfaction either in a positive or negative way. Also, there definitely exists a direct relationship between a workerââ¬â¢s identity and the amount of salary on which he or she is employed in any organization. Workers getting high salaries tend to be more satisfied with their identities and enjoy high self-esteem in comparison to low-profile workers who get paid poorly and who also consequently, tend to face the pressures of low self-esteem and poor social identities. Maintaining the nature of work identity also holds huge importance once a worker enters the workplace and the type of management pr acticed in that workplace also shares a relationship with whether a worker would be able to maintain his or her identity or not. Much research has been done on workersââ¬â¢ identities, which has effectively changed the way relationship with organizations is perceived presently by the workers. More and more managers these days are seen increasingly focus on the concept of organizational culture and trying developing familiarity with the organizational culture and the nature of culture-oriented issues helps in proper maintenance of identity. It is mentioned by Grey that a highly professional and concerned approach is required in every organizational setup for addressing various critically important factors like workersââ¬â¢ skills and identity issues. The concept of organizational culture is heavily related to the potential to reformulate the concept of workforce identity, as mentioned in the work compiled by Grey. It is discussed by the author in the book that cultural concept got introduced in the American management system earlier in the 1980s. Actually, the cultural idea proposes that the organizational practices should be designed in such a way that they would promote the shared values because the establishment of shared values ultimately leads to solidifying the workersââ¬â¢ identities, as already discussed. For stable cultural management, it is critically important that the staff should have a firm belief in values instead of going along with the orders of the managers like feeling fewer automatons. There should remain no distance between individualsââ¬â¢ purposes and those of the organization in which they are employed. According to the theoretical approach introduced by Willmott, culture management has the serious potential to reformulate identity in harmony with the managerial doctrine. This theoretical approach professes that culture management should actually be perceived as a powerful tool through which internal world of an organization can be reshaped in terms of the identity of people at work. With the help of a historical approach, Grey discusses how Japanese managers laid greater emphasis on motivating the employees in order to commit them to working on united goals during the 1970s and 1980s, so that company output could be enhanced along with customer service.Ã

Role of Budgets and Resource Allocation in Implementing and Executing Essay
Role of Budgets and Resource Allocation in Implementing and Executing Strategy - Essay Example Apparently, budgeting ensure that implementation and execution process has been assessed in order to determine amount of resources need for the process. According to Ireland, Hoskisson and Hitt (2009), the budgeting stage of strategic planning is undertaken based on chronology of activities required for achievement of objectives. In fact, this can lead to enhanced processes in the organization such as effective utilization of resources and establishment of effective management practices (Ireland, Hoskisson & Hitt, 2009). Therefore, there is need for understanding budgeting in a systematic way, which is important in realization of processes that are composed such as establishment of objectives, setting targets, monitoring performance and allocation of resources (Spee & Jarzabkowski, 2011). On the other hand there is need for budgeting with aims of addressing particular areas of strategy, which are categorized under implementation plan, organizational change management strategies, stra tegic financial management, and risk management plan. Environmental Sustainability Relate to Implementing and Executing Strategy Implementation and execution of a strategy in an organization is highly influenced by various environmental factors; in fact, strategic planning which entails budgeting considers these effects. For instance, an organization operates in a competitive business environment due to importance of effective strategic environmental planning. In this case, an environmental scan can be undertaken through a SWOT analysis, whereby the analysis focuses on strengths and weaknesses, which forms the internal environment of the organization and threat and opportunities that involve external environment (Spee & Jarzabkowski, 2011). In fact,... Role of Budgets and Resource Allocation in Implementing and Executing Strategy The paper will focus exploring significance of and the role of budgeting and resource allocation, and environmental sustainability to implementing and executing strategy. In this case, an organization formulates objectives concerning their budget, whereby they are focus on ways to reach break-even point within a stipulated timeframe, which is identified to be before completion of their action items. Barr and McClellan (2010) argue that for the purpose of achieving this aim, an organization should acquire sufficient capital, which will enable them avoid scenarios in which expenses surpass income leading to a loss during the process of implementing and executing a strategy (Hill & Jones, 2008). Financials of this institution should be established on the basis of a contingency approach to ensure that unforeseen events do not affect school operations. Nevertheless, in case the financial situation persistently delivers losses, Barr and McClellan (2010) argues that a reconsideration of pri cing policies. This essay focuses on exploring the roles of budgets and allocation of resources to implementation and execution of a strategy. It also explores the interrelationship of environmental sustainability to execution and implementation of a strategy. Therefore, it is evident that allocation of resources has a signification impact on the process of implementing and executing a strategy since managers ensures that there are sufficient financial and human resources to support this process.

Different key factors that influence the failure of projects Essay
Different key factors that influence the failure of projects - Essay Example Industries view project failures as either a pathological state to be avoided or a logical problem of goal definition (Lindahl & Rehn, 2007). This paper will focus on the different key factors that influence the failure of projects especially on the field of information technology (IT). It will discuss the different stages in the project lifecycle and the possible areas of failures in each stage. Furthermore, the paper will tackle the concept of risk management and its benefits in a successful project development as well as in preventing failures. A successful risk management system incorporated in a project will create a programme for handling probable causes of project failures. IT projects fail when it does not meet one or more of its criteria for success. The criteria for successful IT projects are delivery on time, completion on or under budget, and satisfaction of user requirements. Only a few projects achieve all three (Grossman, 2003). In summary, failure can be defined as a system which does not perform as expected, not operational at a specified time and cannot be used in the way expected. There are four key factors that can be associated with project failures. These are design, data, cost and operations. A poor design phase can result in a system that does not match customer expectation, or fails to capture the basic business requirements. The data factor may include inaccurate, inconsistent, not available or incomplete information and records. The cost factor involves the operational costs to implement and run the system that far exceeds the identified business benefit. A survey showed that 35% of all major information systems projects are over budget, termed "runaways", such as the Stock Exchange Taurus Project and the London Ambulance Service (Flowers, 1996). Project Lifecycle The project lifecycle defines the beginning and the end of a project. It is a collection of generally sequential and sometimes overlapping project phases whose name and number are determined by the management and control needs of the organisation (Project Management Institute, Inc, 2008). It also determines which transitional actions are included and which are not in every stage of the project from beginning to end. It can be used to link the project to the ongoing operations of the organisation. (Choudhuri, 2005) The first phase of the lifecycle is the initiating process which involves those processes performed to define a new project by obtaining the authorization needed to start the project. The second phase is the planning process which includes those processes required in establishing the scope of the project, refining the objectives, and defining the course of action in order to attain the objectives of the project. The third phase is the executing process which encompasses those processes performed to complete the work defined and to satisfy project specifications. The fourth phase is the monitoring and controlling process which includes those processes required to track, review, and regulate the progress and performance of the project. The last phase is the closing process which considers those processes performed to finalise all activities to formally close the project. (Project Management Institute, Inc, 2008) Causes of Project Failures In every phase of the project

Analyse and discuss the advantages and disadvantages, pros and cons, Assignment
Analyse and discuss the advantages and disadvantages, pros and cons, of group decision making. What aspects should be avoided in multi departmental decision making in order for them to be effective - Assignment Example the success of any organisations are denoted by the strategic decisions made through initiatives such as group decision making and other strategic positioning plans. Nevertheless, specific aspects of decisions should be avoided in order to make departments effective. Stone (2013) articulated on core aspects that touches on sensitive matters and which should be avoided for effective running of organisations. In fact, Freeman (1999) further argued that group decision making can only yield good results if a set of conditions pertaining the group chemistry are met. It is evident that group members have different skills and competence. Thus, sharing of ideas and information on a particular issue can lead to more information and more comprehensive. The ground for the argument is many alternatives are provided and the most appropriate one is chosen from the list. This is unlike in situations where one individual is left to make decisions that affect a whole company or department. Chances of getting the best outcome are minimal when compared to individual decision making. In addition, the whole process becomes effective since issues related to revising the decisions made are minimal especially because the whole group is present or representatives are present during decision making. Thus, group decisions are acceptable by all since everybody is represented during the process. DuBrin (2012) conversely observed that, with group decision making, biases are eliminated especially those that come in as a result of lack of inclusion of the target individuals. In a broader sense, group decision making acts a training ground for subordinate and new members. They learn skills of articulating on matters as well as the importance of collaborative workforce. Further, group decision making is viewed as a democratic style of leadership, which is inclusive and accommodates views from all the parties and consolidate them before arriving into a single decision that suits everybody.

Buddhist Psychology Essay Example | Topics and Well Written Essays - 2000 words
Buddhist Psychology - Essay Example But as we begin to discover more of ourselves, and we begin to understand and honor the presence of things and people around us, we become less of a person who is self-seeking but we are slowly being transformed to become self-giving. The more we enjoy the meaning of ourselves, the more we want to share it or give part of ourselves away. As we get to know each other more, it is much simpler to be generous to others, in almost everything. This is because of our increased sense of security, we have taken from our self-awareness. In my opinion, a person who is self aware, is less insecure. We become more comfortable even in unknowns spheres and parameters. We are no longer confined to restrictions and it becomes a need to share what we are and who we are. Buddhism or Psychotherapy invokes that the further we look at/into our selves the further we are perpetuating the notion of no self. No self basically means letting go of narcissistic notions and furthermore allowing oneself to become part of a bigger picture in the world. This may sound very paradoxical but this can be explained in several ways. For example, the more we are in touch with our senses, the better we perceive the senses of others. Our personal sensitivity becomes not just means to promote our own needs but also to meet the needs of others. Simple fact such as being sensitive to foul smell, we cannot just easily ignore it, because our senses can perceive it, at the same time we subconsciously know that others smell it too, thus we begin to "care" about others, and how they would perceive things. This is purely a function of departing from our own self.Such tendency allows us to discover our inner connection to the world and other beings. As Aristotle says, men indeed are social beings. We are born to form communities and relate with fellow beings. This way of looking at ourselves, will definitely bring us back to the essentials of becoming social beings.According to Mark Epstein, "What Buddhism teaches is that the connection, the ability to find intimacy or connection, is inherent within us, and that if we can j ust surrender back into that capacity for love, that is all of our birthrights--all babies are born with that; they instinctively love their caretakers. So if we can find that again, then our relationships will take care of themselves."(Epstein, 2005) Mark Epstein pioneered the Eastern teachings of non-self, something that is so different and new to the Western mind. Instead of the usual or traditional Western teaching of separation, individuality as the ultimate psychological goals of human development, he opted to create a theory that is based on connection. Through Buddhism, the idea of "self" becomes a part of a certain whole- which is the universe. Each soul or person becomes a vehicle of spirituality, common to all people. Thus, if we look deeper within ourselves, we find it natural to relate and connect with other people because there is something common amongst all of us, it can be the presence of a higher being within us, or simply the common kind of spirituality which has

Personal Position paper on Psychotherapy Essay Example for Free
Personal Position paper on Psychotherapy Essay Introduction ââ¬Å"People are always changed by disasters, and other life events, but they need not be damaged by them.â⬠-John D. Weaver à à à à à à à à à à à When we study human behavior, specifically focusing on the development of personality and crucial to how a person or individual conducts him/herself, psychology offers a variety of dimensions. The concept of personality is central to our attempt to understand ourselves and others and is part of the way in which we account for the differences that contribute to our individuality. Psychologists have been particularly concerned with shaping of the personality in relation to genetic and environmental influences. We have been fortunate that the study of human personality has been thriving and fruitful. We can choose from as many models we can to help us see ourselves better and maintain good relationships. à à à à à à à à à à à In the course of our study, every individual counselor ââ¬â therapist eventually develops his/her own approach in the therapeutic process. The path that the practitioner takes concerning his/her choice of approach or model depends a lot on his/her own personal preferences, personality and understanding of human nature. An eclectic approach is usually the direction that anyone in this field would take; however, certain emphasis is made on some specific positions simply because these are the dominant theories which help guide him/her in focusing the essentials of the process with the client.à Though the attempt is said to be eclectic then, the therapist still has this open option to change or vary some details of his/her strategy along the course of the interaction or treatment phases. Discussion à à à à à à à à à à à There is a need for integration not only for its theoretical applicability but also for its practical usefulness. Presuppositions or philosophical conceptualizations are the pillars of any worldview, and to successfully establish a new one requires that changes or reinforcements be made at this plane. The integrative approaches were framed at this level so as to remove mental oppositions as they arise every time in oneââ¬â¢s thoughts. When this is not adequately laid down, no audience can align their thoughts or understanding with what the author tries to convey. This paper is an attempt to convey a personal understanding of human behavior in the context of psychotherapeutic approaches that are modified for use by the author. It appreciates the accomplishments of the various approaches such as Behavioral, Cognitive-Behavioral, Psychoanalytic, Existential, Humanistic, Family Systems, Gestalt and Client-Centered developments in the profes sion. The following reflects the views of the author in the healing process of the mind and emotions. Key Concepts of My Approach à à à à à à à à à à à It is therefore expected that though at this point I value the primary theories or perspectives that I am thus enumerating afterwards, this also implies that I am open to the various developments that are expectedly to occur in my practice in the future. Since this is an eclectic approach at employing strategies I have found to be beneficial personally and that of others, I wish to mention many of these in the following statements. I am persuaded further that key elements or themes are found all throughout my own version of the approach. The smaller yet finer points come only in the between. For the thrust that this paper is taking, I wish to mention then my views individually, on Behavioral, Cognitive-Behavioral, Psychoanalytic, Existential, Humanistic, Family Systems, Gestalt and Client-Centered approaches. Behavioral Therapy à à à à à à à à à à à This model utilizes what is termed as the learning theory posited by Skinner and Watson and the rest of the Behaviorism school. It assumes that the principles in learning i.e., conditioning (Associative and Operant) are effective means to effect change in an individual. Generally, the thrust of this theoretical perspective is focused on the symptoms that a person is experiencing. Just as many of the errors of the patterns of behavior come from learning from the environment, it is also assumed that an individual will be able to unlearn some if not all these by using the techniques as applied based on the learning principles. To a certain extent I believe that this still works: reinforcements are effective to some extent and in some or many people hence I am incorporating this stance separate or distinct from the Cognitive-Behavioral approach. à In behavior therapy therefore, thoughts, feelings and all those ââ¬Å"malfunctioningâ⬠an d unwanted manifestations revealed in oneââ¬â¢s activities can be unlearned and the work of a behavior therapist. The basic concepts include ââ¬Å"extinguishingâ⬠ââ¬â utilized when maladaptive patterns are then weakened and removed and in their place habits that are healthy are established (developed and strengthened) in a series or progressive approach called ââ¬Å"successive approximations. When these (factors) are reinforced such as through rewards in intrinsic and extrinsic means, the potential of a more secure and steady change in behavior is developed and firmly established (Rubinstein et al., 20074; Corey, 2004). Although few psychologists today would regard themselves as strict behaviorists, behaviorism has been very influential in the development of psychology as a scientific discipline. There are different emphases within this discipline though. Some behaviorists contend plainly that the observation of behavior is the best or most expedient method of exploring psychological and cognitive processes. Others consider that it is in reality the only way of examining such processes, while still others argue that behavior itself is the only appropriate subject of psychology, and that familiar psychological terms such as belief only refer to behavior. Albert Banduraââ¬â¢s social cognitive approach grew out of this movement. Banduras method emphasizes cognitive processes over and above observable behavior, concentrating on not only the influence of the personââ¬â¢s upbringing for example, but also observation, imitation, and thought processes (Plotnik, 2005). Cognitive-Behavioral à à à à à à à à à à à In the cognitive approach alone, the therapist understands that a client or patient comes into the healing relationship and the formerââ¬â¢s role is to change or modify the latterââ¬â¢s maladjusted or error-filled thinking patterns. These patterns may include wishful thinking, unrealistic expectations, constant reliving and living in the past or even beyond the present and into the future, and overgeneralizing. These habits lead to confusion, frustration and eventual constant disappointment. This therapeutic approach stresses or accentuates the rational or logical and positive worldview: a viewpoint that takes into consideration that we are problem-solvers, have options in life and not that we are always left with no choice as many people think. It also looks into the fact that because we do have options then there are many things that await someone who have had bad choices in the past, and therefore can look positively into the futu re. Cognitive-Behavioral Therapy postulated primarily by Ellis and Beck ââ¬Å"facilitates a collaborative relationship between the patient and therapist.â⬠With the idea that the counselor and patient together cooperate to attain a trusting relationship and agree which problems or issues need to come first in the course of the therapy. For the Cognitive Behaviorist Therapist, the immediate and presenting problem that the client is suffering and complaining from takes precedence and must be addressed and focused in the treatment. There is instantaneous relief from the symptoms, and may be encouraged or spurred on to pursue in-depth treatment and reduction of the ailments where possible. The relief from the symptoms from the primary problem or issue will inspire the client to imagine or think that change is not impossible after all. In this model, issues are dealt directly in a practical way. Coaching the patient on the step by step procedure of CBT is a basic and fundamental ingredient. Here the client is enlightened as to the patterns of his thinking and the errors of these thoughts which bore fruit in his attitudes and behavior. His/her thoughts and beliefs have connections on his/her behavior and must therefore be ââ¬Å"reorganized.â⬠For instance, the ways that a client looks at an issue of his/her life will direct the path of his reactivity to the issue. When corrected at this level, the behavior follows automatically (Rubinstein et al., 2007; Corey, 2004). Psychodynamic Therapy à à à à à à à à à à à The Psychodynamic perspective is based on the work of Sigmund Freud. He created both a theory to explain personality and mental disorders, and the form of therapy known as psychoanalysis. The psychodynamic approach assumes that all behavior and mental processes reflect constant and often unconscious struggles within the person. These usually involved conflicts between our need to satisfy basic biological instincts, for example, for food, sex or aggression, and the restrictions imposed by society. Not all of those who take a psychodynamic approach accept all of Freudââ¬â¢s original ideas, but most would view abnormal or problematic behavior as the result of a failure to resolve conflicts adequately. Many of the disorders or mental illnesses recognized today without a doubt have their psychodynamic explanation aside from other viewpoints like that of the behaviourist, or the cognitivists. From simple childhood developmental diseases to Schizophrenia, there is a rationale that from Freudââ¬â¢s camp is able to explain (Kaplan et al, 1994). Existential Therapy à à à à à à à à à à à The Existential approach, as put forward by Nietzsche, Kierkegaard, Sartre, Heidegger, Rollo May, and Frankl, believes that the individualââ¬â¢s potential may lie dormant but that it is there waiting to be ushered in time. It recognizes that man is able to achieve great heights and that these are just waiting to be tapped not only by him/herself but that also when helped by a practitioner who is persuaded of this notion. It examines such major issues as free will and the challenges of exercising this free will, the issue of mortality, loneliness and in general, the meaning of life. The Therapy is effective when the practitioner works with elderly care and death and dying issues. It focuses on the individual needs but takes into consideration the significant relationships and the meanings they bring into the personââ¬â¢s life. Transcending the issues and problems are primary intentions of the therapist at the same time being realistic that certain limitations do exist and may hinder the process of recovery (Rubinstein et al., 2007; Corey, 2004). Humanistic Therapy à à à à à à à à à à à Allport, Bugental, Buhler, Maslow Rollo May, Murphy, Murray, Fritz Perls and Rogers are those that helped usher in the Humanistic theory and consequent therapy. It holds in view the individual as possessing the options or freedom to choose, creativity, and the capability to attain a state where he/she is more aware, freer, responsible and worthy of trust. Because the human mind has immense potential, the approach assesses as well that forces from the environment bear on with the individual and depending on the interplay that occurs within the individual person, the result will either be destructive or constructive to the person. In sum, humanism takes into the perspective that essentially humans are good and not evil, and that the therapy facilitates by harnessing on the human potential through the development of interpersonal skills. This results to an enhanced quality life and the individual becomes an asset rather than a liability to th e society where he revolves in (Rubinstein et al., 2007; Corey, 2004). Family Systems Therapy à à à à à à à à à à à This theoretical viewpoint has been the by-product of the works of Bateson, Minuchin, Bowen, Ackerman and many others. Usually done in pairs or by a team of practitioners, family systems therapy has its roots in behavioral and psychoanalytic principles. This model understands that the family is a unit and its members or any of its members with an issue or a problem must be addressed in the context of the family as a unit. It puts its emphasis on the relationships among the family members, their patterns of communication more than their individual traits and/or symptoms. The systems theory portion of the therapy indicates that whatever is occurring or happening is not isolated but is a working part of a bigger context. In the family systems approach then, no individual person can be understood when removed from his relationships whether in the present or past, and this is specially focused on the family he belongs to (Rubinstein et al., 200 7; Corey, 2004). Gestalt Therapy à à à à à à à à à à à Gestalt therapy has this goal of reducing if not removing the symptoms with the rationale that the individual has personal responsibility and that the here-and-now experience is thus very important. This two-fold emphasis on the present moment as experienced by the person and that another reality is that our existence is entangled actually with other aspects and parts of the environment. It is when we understand that we are related with other things that insights to our issues are achieved and help us in finding solutions to our existence. When we are free from the obstructions of things that are ââ¬Å"unfinishedâ⬠then we reduce the obstacles and enhance the opportunities to our optimal satisfaction and fulfillment and eventual growth (Rubinstein et al., 2007; Corey, 2004). Client-Centered Therapy à à à à à à à à à à à Developed and known because of the works by one person ââ¬â Carl Rogers ââ¬â Client Centered Therapy focuses on the person who needs aid and his/her improvement depends on the client himself although with the facilitation and assistance of the therapist. The rationale for the direction of the therapy lies in the notion that humans basically possess the ability to move towards the fulfillment of his/her possibilities. According to Rogers, ââ¬Å"Individuals have within themselves vast resources for self-understanding and for altering their self-concepts, basic attitudes, and self-directed behavior; these resources can be tapped if a definable climate of facilitative psychological attitudes can be providedâ⬠(Rogers, 1980, p 115-117 in Rubinstein et al., 2007). à à à à à à à à à à à This approach is very popular today and many therapists usually incorporate this model into their own eclectic method. Rogers identified three important concepts termed as conditions: these are congruence, unconditional positive regard and empathy. Many in the mental health circles have these in their day-to-day jargon. In the aforementioned conditions, a person moves toward what Rogers call ââ¬Å"constructive directionâ⬠when these three conditions are afforded. The Role of the Therapist à à à à à à à à à à à I aspire to be a therapist ââ¬â counselor whose practice is characterized as empowering and collaborative. By empowering, I understand the limitations of my role and as such I am constrained at the same time to impart my best knowledge and efforts to enable my client/patient to understand him/herself, and lead the treatment to the point where he/she is able to stand on his/her own without my help anymore. Further, it means that I recognize the patient or client as a person who is not only complex, he/she is also is imbued with the nature that inherently can heal, grow and mature. They contribute to the process, and their attitude towards the whole duration of the healing relationship is a crucial aspect to the attainment of their goals. The therapist then must remove by all means any barrier or obstruction to the achievement of goals especially when these come potentially from the therapist him/herself (thatââ¬â¢s me). By collaborative, again because there are set limitations on my capacities, I recognize the availability and expertise of others in realms that I hardly know and that working with them, collaborating with them, gives my client more options, and provides him/her the best and comprehensive interventions that there is in the field. A therapy that is beneficial looks beyond my set style and preferences of diagnosis and treatment; it is progressive and seeks to enhance the initial strategies that had been established and continually expands oneself by learning and researching. Most importantly, by collaboration, my client is the most significant ââ¬Å"collaboratorâ⬠and that notion should not be missed all throughout (Rubinstein et al., 2007; Corey, 2004). . à à à à à à à à à à à The effectiveness of therapy in counselling is dependent substantially on two factors; namely, the patientââ¬â¢s cooperation, and the expertise of the therapist. Many experts in the field of Psychology have observed the significant contribution of the client to the over-all process. The individualââ¬â¢s perception of the therapist is extremely crucial to the ensuing treatment. Without the needed initial positive perception of the therapist on the part of the one seeking treatment, the whole process will not generate a desired momentum that would set the entire scheme in a strategic stance. Of course, the expertise of the therapist is another major factor ââ¬â actually, the other half ââ¬â but itââ¬â¢s a given to the whole package of treatment (Rubinstein et al., 2007; Corey, 2004). à à à à à à à à à à à Since a ââ¬Å"working allianceâ⬠has to be established first before the actual treatment is administered, there are important or vital considerations for this ââ¬Å"working allianceâ⬠between client and therapist to occur, and this is in prà ©cis, the intentions of this paper. What we will be considering in this paper are the challenges that new therapists face as they practice their profession. The past baggage of the client. à à à à à à à à à à à From any vantage point, the level of trust by client on his therapist, whether that perception is based on attractiveness, trustworthiness or as someone who knows what he may be dealing with in terms of credentials, are valid, and is the utmost concern of the helping relationship. Trust in the part of the client is necessary for the healing process. However, because the full ramifications of the issue almost always hinge on the perceptions of the client, the problems and hindrances need to be addressed or at least cited for clarity and deliberation at the outset of the relationship. As hinted above, the client may be bringing (emotional) baggage into their mutual involvement which may be due to prior engagements with other professionals in the therapeutic relations, whether positive or negative. Oftentimes, in many cases, these may be liaisons which were unsuccessful, distasteful or even traumatic for a few. The author pointed out that any form of future therapy will be affected due to these previous experiences, and it has to be dealt with right away at the outset (Horvath Luborsky, 1993, p. 4). The fitness of the therapist à à à à à à à à à à à By fitness, we mean sufficient, wide-ranging exposure, and right training to the kind of illness/es or disorder/s that he may be dealing. Even with years spent in the academe will not guarantee the development of skills in handling such complex and true-to-life situations or scenarios. At times, the theoretic skills acquired, instead of enabling the new therapist, may deter or hamper the process. This means to say that the therapist must possess more than head-knowledge; he should not allow his schooling to affect him to the extent that it made him conceited with no room for more learning especially when additional knowledge are available in the patient himself. He must also have the sensitivity to employ his gut-feeling to at times, direct the course of the therapy (Rubinstein et al., 2007; Corey, 2004). Therapeutic relationships are almost always exhausting, but it will be an undesirable experience for the alliance partners when just one of them becomes disinterested, hence as Luborsky pressed that ââ¬Å"reciprocityâ⬠must be established, cultivated or maintained until the relationship is terminated, hopefully because the client is well (Horvath Luborsky, 1993, p. 4). III. The Therapeutic Process à à à à à à à à à à à The therapeutic process is initiated by the therapist primarily as soon as the client or others who refer or brought the patient in for the assumed long haul of the healing relationship. It would be impossible to do all approaches at one time. By eclectic and as frequently emphasized, the usage of any of the methods will be dependent on the need of the patient, and other pertinent information that help guide which of these the therapist will be using. The therapist then is enjoined to be able to diagnose well; it is at this stage that any practitioner is well aware of the risks should he/she fail to diagnose properly the needs and or issues /problems of the client. However, as he/she matures and advances in the profession, many instances occur that the mistakes made in diagnosis are oftentimes corrected while at the treatment stage, hence the traits of flexibility and humility (admitting mistakes for instance) are valued highly in this pro fession (Rogers, 1980, p 115-117 in Rubinstein et al., 2007). à à à à à à à à à à à Employing the Behavioral, Cognitive-Behavioral, Psychodynamic, Existential, Humanistic, Family Systems, Gestalt and Client-Centered Eclectic stance primarily involves the incorporation of distinct concepts within a single framework. The important thing is that of flexibility and resiliency on my part when to apply or implement which of the theories in the context of my client. It starts with the identification of specific problems and especially the root causes. When this is confidently achieved, the therapist is actually midway to attaining his/her goals which includes not only the relief of the symptoms that the sufferer is currently experiencing but especially the reduction of the occurrence if not altogether eliminated. The specific treatment goals are likewise essential and it helps in the remaining aspects or levels of the process. The diagnostic part by itself in most cases is considered therapeutic since many clients have experienced immediate relief; in the language of psychoanalysis, the ââ¬Å"catharticâ⬠effect is helpful already. In addition, another important ingredient in the process is to identify effective reinforcers which help people in crisis for instance or those in acute and chronic mental and emotional anguish to sustain their plan for change and control of their disorders. Helping the client set up a kind of self-help management program is a very effective strategy to pursue within the relationship (Rubinstein et al., 2007; Corey, 2004). ~Identifying clients in crisis à à à à à à à à à à à Despite breakthroughs in scientific researches and the success of many crisis interventions by established churches, there are ââ¬Å"fly by nightâ⬠operations which prey on funding of private and government groups on such types of operations. There are those who minister lacking the necessary spiritual maturity and corresponding abilities in this kind of endeavor, hence the necessity of proper credentials to minimize abuses in the profession (Buttman, p.59). Crucial to the treatment or interventions of people in crisis is the identification of clients experiencing crisis in life. ââ¬Å"Knowledge of the three core components of crisis intervention theory (a precipitating event, client perception of the event, and the clientââ¬â¢s usual coping methods)â⬠is essential in this kind of work (Walsh et al, 2005). The Goal of Therapy à à à à à à à à à à à Trauma inducing and crisis triggering situations have spiraled its occurrence and in its primacy in the US and in many other countries in recent years. Its broad spectrum ranges from the national disaster category such as that of Hurricane Katrina or the 911 terrorist strikes in New York, Spain and England, to private instances such as a loved oneââ¬â¢s attempt at suicide, the murder of a spouse or child, the beginning of mental illness, and the worsening situation of domestic violence (Teller et al, 2006). The acute crisis episode is a consequence of people who experience life-threatening events and feel overwhelmed with difficulty resolving the inner conflicts or anxiety that threaten their lives. They seek the help of counselors, paramedics and other health workers in crisis intervention centers to tide them over the acute episodes they are encountering. These are defining moments for people and must be adequately addressed else they lead lives with dysfunctional conduct patterns or disorders (Roberts et al, 2006). à à à à à à à à à à à In the integrated or eclectic approach the goal of the therapy is not just relief to the patient or client. Although an immediate relief is very helpful, this may not always be the case in most illnesses. The goal as mentioned in the preceding pages is to provide long-term reduction of the symptoms and the occurrence of the disease altogether if possible. The management then is not impossible but neither is this easy. Specifically, the counselee or patient must want to heal or believe that there is going to be curative effects in the process. It presupposes that he/she must learn to trust the therapist in his/her capabilities as well in leading or facilitating the changes or modifications. It is very much essential that (in the perspective of a cognitive-behaviorist) that the client understands ownership to the deeds and choices in thought patterns he/she made are crucial to the recurring or occurring condition that s/he experiences (Rubinstein et al., 2007; Corey, 2004). à à à à à à à à à à à Moreover, the identification of specific treatments or interventions according to the diagnosed issue will be accommodated and implemented based on the chosen treatment modalities fit with the therapeutic approach utilized. It may be a single modality based on a single approach (e.g., learning principles and desensitization for a patient with specific phobias) or it maybe a combination of many modalities (CBT, Rogerian, Phenomenological, or Family systems) (Rubinstein et al., 2007; Corey, 2004). The Nature of the Relationship between the Therapist and the Client à à à à à à à à à à à The client throughout the process is a person in need of help and support and this reality is throughout reinforced in the process until the need to terminate the relationship. The therapist is the helper, who ushers the client to discover insights into his needs and problems and until the client is able to stand on his/her own the therapist aids him/her in more ways than one. Because of usual and common abuses that either the client suffers or that the therapist at times undergoes, definite boundaries are set in place at the outset. This must be established at the initial stage and from time to time emphasized to mind either of the parties in the limits of the relationship. The therapist is guided by morality and ethics of his/her profession in the proper exercise of his/her duties and bound by law to implement this in the process and make this known as well to the client. The therapist terminates the relationship readily or refer the cli ent to another competent practitioner should the limits be reached and the relationship has become unrealistically difficult for either of the two parties. Best Practices for Techniques à à à à à à à à à à à Techniques or the utilization of various modalities come in a variety of forms and each when employed has the potential to meet the individualââ¬â¢s needs. The modality of choice at particular client/patient depends on such considerations as family support, financial constraints or financial capability, the patientââ¬â¢s preference, diagnosis, and age of patient (Rubinstein, et al., 2007). Employing the cathartic method, teaching the client to examine his/her thought patterns, to discern the errors of judgment and gain insight into him/herself, and to handle with patience the whole process are fundamentals in the process. When the therapist is able to shift effectively in various standpoints and enables the client to gain a better, realistic and eradicate unrealistic expectations of the self and others, they are both on the way to achieving wholeness and healing that which the client so need and aspire. This requires practice, or con stant training and endurance on the part of the therapist (Rubinstein et al., 2007; Corey, 2004). VII. Methods of Therapy à à à à à à à à à à à Every theoretical approach has its own assumptions. In the psychodynamic theory, the following three assumptions help guide a student of human behavior or an expert in this field determine the underlying factors that explain the overt manifestations of specific behaviors. These assumptions therefore, help guide the diagnosis of the presence or absence of mental illness. They are the same assumptions that guide the therapist in choosing what treatment that will better help heal, cure or alleviate the symptoms. à à à à à à à à à à à These assumptions are: ââ¬Å"There are instinctive urges that drive personality formation.â⬠ââ¬Å"Personality growth is driven by conflict and resolving anxieties.â⬠ââ¬Å"Unresolved anxieties produce neurotic symptomsâ⬠à à à à à à à à à à à (Source: Kaplan et al, 1994). à à à à à à à à à à à The goals of treatment here include alleviating patient of the symptoms which specifically works to uncover and work through unconscious conflict. The task of psychodynamic therapy is ââ¬Å"to make the unconscious conscious to the patientâ⬠(ââ¬Å"Models of abnormalityâ⬠, National Extension College Trust, Ltd). Employing the psychodynamic viewpoint, the therapist or social scientist believes that emotional conflicts, or neurosis, and/or disturbances in the mind are caused by unresolved conflicts which originated during childhood years. In the psychodynamic approach the treatment modality frequently used includes dreams and free association, at times hypnosis (as preferred by either the therapist or by the client). The therapist actively communicates with the client in the on-going sessions. The scenario appears that a given patient may have up to five times a week session and runs up to five years in length (Rubinstein et al., 2007). à à à à à à à à à à à The methods of therapy incorporate the methods of the eight models. In Behavioral Therapy ââ¬â the development of behavioral skills that encourage effective actions which is done through incorporating principles in learning or classical and operant conditioning. It utilizes shaping, modeling and such concepts as behavior modification, counterconditioning and exposure, and systematic desensitization. à Behavioral or action therapies utilize insight just as much as the psychodynamic model. Just as the cognitivebehavioral model also recognizes the concept of insight as well, this is only a matter of emphasis or focus. In behavioral/cognitive-behavioral therapies the focus is on the modification or control of behavior and insight usually becomes a tangential advantage. Techniques include CBT through such strategy as cognitive restructuring and the current frequently used REBT for Rational Emotive-Behavior Therapy where irrational beliefs are eliminated by examining them in a rational manner (Corey, 2004; Davison and Neale, 2001). Whereas in insight therapies the focus or emphasis is on the patientââ¬â¢s ability in understanding his/her issues basing on his inner conflicts, motives and fears. Techniques then include reflection of feelings and free association; the former as employed in the clientcentered therapy and with the latter in psychodynamic therapy. Cognitive Strategies are utilized to promote functional thoughts which are likely to result in adaptive and healthy habits (Corey, 2004; Davison and Neale, 2001). à à à à à à à à à à à Client-centered therapy avoids the imposition of goals on the patient or client during therapy. It is the client who takes the lead in the session and of the conversation. It is the job of the therapist to create the conditions conducive to the clientââ¬â¢s positive judgment of those experiences that are intrinsically satisfying to the client. The ââ¬Ëgoalââ¬â¢ then is to reach the point where the client desires to be a good and ââ¬Å"civilized person.â⬠Unconditional positive regard enhances this atmosphere however, and although the goal may be difficult to achieve, unconditional positive regard eventually, according to Rogers, encourages even the ââ¬Å"`unbehavedâ⬠to conform or even transform (Corey, 2004; Davison and Neale, 2001). Gestalt therapy techniques on the other hand, include the I-language, The Empty Chair, Projection feelings, Attending to Nonverbal Cues, and the Use of Metaphor (Corey, 2004; Davison and Neale, 2001). à à à à à à à à à à à The techniques may sound a lot like pulling ââ¬Å"this and thatâ⬠from oneââ¬â¢s tool box but in practice it is far from whimsical and impulsive. There is given time to much thought and analysis per client and an evaluation in between is mustered in order to be kept on track according to the specific goals that had been established at the outset. Here, professionalism counts and much of the efforts poured into every patientââ¬â¢s benefit. à à à à à à à à à à à In order to avoid what Corey says as a syncretistic and hodgepodge type of ââ¬Å"eclectismâ⬠a theoretical rationale must be underpinning in the overall approach of the therapist (Corey, 2001, Article 29 in Lazarus, 1986, 1996; Lazarus, Beutler, Norcross, 1992). This means that I as the therapist must establish firmly my own worldview, which contains my value system, and communicates this at the outset to the client and intermittently in the therapeutic process.

Human Error and Perceptual Control Theory
Human Error and Perceptual Control Theory Overview In this paper, I will explore and advocate the importance of both Human Error and Perceptual Control Theory for design of complex human-machine systems, enhanced user experience and better human performance and safety. Human Error Errors are the result of actions that fail to generate the intended outcomes (SKYbrary). Human operators are one of the biggest sources of errors in any complex system (Shelton, 1999). According to Sanders McCormick (1976), Human error is an inappropriate or undesirable human decision or behavior that reduces, or has the potential for reducing effectiveness, safety and performance of a system and/or human (Kurniawan). Error Types Researchers have differentiated between two types of error:1) slipsand lapses 2) mistakes. Slips and lapses According to SKYbrary, a person intends to carry out an action, the action is appropriate, carries it out incorrectly, and the desired goal is not achieved an execution failure has occurred. Execution errors result from failures in the execution and/or storage stage of an action sequence. Slips relate to observable actions and are commonly associated with attentiveness or perceptual failures. Lapses are more internal events and generally involve failures of memory (SKYbrary). Mistakes As mentioned in UKEssays.com, Mistakes occur when an intended outcome is not achieved even though there was adherence to the steps in the plan. This is usually a case in which the original plan was wrong, was followed, and resulted in an unintended outcome (UKEssays.com). Error mechanisms The following three error mechanisms are widely accepted, which correlate with human performance levels. Skill-based errors Errors of execution Occur during highly routine activities or automated tasks with occasional checks Action chosen by the operator but not in accordance with the operatorââ¬â¢s intentions Done by highly experienced individuals due to inattention or distraction Rule-based errors Applies to familiar situations Incorrect application of a good rule, correct application of a bad rule or failure to apply a good rule Knowledge-based errors Occur in unique and unfamiliar situations Result from inadequate analysis or decision making (trial and error) Done by operators with insufficient knowledge Applications of Human error theory Human error is inevitable. However, human error mitigation strategies could be devised by understanding various error mechanisms and triggers, as depicted in the human error theory. Superior system design, better recruitment and selection of operators, training, stress and fatigue prevention measures, better equipment procedures and improved work environment can reduce error consequences and likelihood. By understanding human error, system designers can plan for likely error scenarios, and implement barriers to prevent or mitigate the occurrence of potential errors. Some approaches to build a better human machine interaction system are explained below. Identification of error environment First step in human error mitigation approach is to understand the work environment, recognize capacity of the users, identify possible loopholes n the system and be familiar with potential user error occurrence and consequences. Likelihood of an error and severity of potential harm should also be examined. For example, FDA (Food and Drug Administration) requires manufacturers to submit a failure analysis report FMEA (Failure Mode and Effect Analysis) while launching any new medical device. Design solutions to address errors Error elimination First and foremost design strategy is to eliminate design features, which are sources of user errors. Design weaknesses identified during observation and task analysis should be removed or revised. Removal of excessive and irrelevant information, inclusion of validity checks and task automations are some design aspects that support error elimination approach. Additionally, carrying out periodical test runs of the system might be helpful in eliminating some of the rules based errors. Error reduction Designers should try to reduce error occurrences for features that cannot be removed completely. Building consistent designs and providing alerts, warnings, confirmations and other necessary feedback to users may prevent users to make errors of execution (skill-based errors). Consequence elimination Consequence elimination is an approach to prevent potential harm after the occurrence of error. Designers can devise features that provide information about potential harm and ways to correct the situation (e.g. undo) and/or prevent onset of side effects (e.g. automatic locking or shutdown, process delays) in order to prevent error consequences. Consequence reduction This is a last design alternative a designer can look into if above mentioned options are not feasible to incorporate. Decreasing the effect of error is helpful especially in catastrophic situations. Design of supplementary features is usually necessary to achieve this purpose. Backup and restore features, automatic reporting to stakeholders/police/medical teams and automated substitute drug delivery are some of the techniques for reducing effects of consequences. Error elimination and error reduction are often the most cost effective methods to avert user errors. Trainings Knowledge-based errors can be eliminated to some extent by providing system-oriented trainings, especially to novice users. On the other hand, a different training program could be devised for experienced users. Periodical trainings could keep experts up-to-date with latest developments in their field and assess their knowledge of system procedural checks. Essentially, this may help minimizing skill-based errors. Perceptual Control Theory (PCT) Perceptual control theory (PCT) is a theory of human and animal behavior. It is based on the principles of control theory (Powers, 1973). As cited by Lulham (2005), at the core of PCT is the idea that many of the processes involved in how human functions are most appropriately conceptualized and modelled as dynamic control processes (Powers, 1999b). Control processes are proposed to be fundamental to many functions including those related to physiological (e.g. temperature regulation), neural (e.g. attention), motor control (e.g. driving a car), psychological (e.g. maintenance of a criminal identity) and social (e.g. staff-detainee relationship) functions (Lulham, 2005). According to Cherry Farrel (1998), PCT exploits the concept of a purpose behind the behaviour. A perception (which is a transformation of stimuli from the world) is then compared to its reference signal, and a perceptual error is generated. A person acts on the world in such a manner to minimise this error. The stabilisation of this control loop is the essence of PCT (Chery Farrell , 1998). Applications of PCT Using perceptions for building complex systems System environments are becoming increasingly complex. Traditional cause and effect methods of understanding system operations and user interactions may not work well in order to employ personalization and user experience in these complex systems. According to pctweb.org, the person compares a ââ¬Ëstandardââ¬â¢ (what they want) with what they are experiencing right now (their perception). The difference between the two ââ¬â the discrepancy or error is being measured. The bigger the error the more the effort the person makes to reduce it, until the error is zero ââ¬â this means they get what they want (pctweb.org). The basic premise of PCT is that human behavior is not about the behavior itself, but about reinforcing desired perception (Oââ¬â¢Neal, 2012). Understanding and applying this concept of individually preferred perceptions through PCT will help in designing effective personal information management for complex systems and enhancing the overall user experience. User research and analysis PCT is particularly helpful in understanding usersââ¬â¢ behaviors and motives behind their actions. Often system designers evaluate possible system states and static change in control values needed to achieve those states. Tasks are carried out on the controls to attain the new state and user is though of as a controller of these tasks. Designers use task analysis method to perform user research and concentrate on physical tasks a user performs. However, instead of system oriented or designer oriented view, PCT goes much deeper and offers userââ¬â¢s standpoint. PCT provides framework to realize dynamic nature of user interactions. System designers can use PCT to understand how users constantly perceive and compare system states and take dissimilar actions to reinstate appropriate system state every time. Furthermore, Powers (1973) proposed behavior as a control of perceptions. Instead of focusing on a physical activity during the task analysis, PCT suggests focusing on usersââ¬â¢ behaviors that lead them to perform actions to achieve desired perception (system state). Thus, using the PCT framework, designers can integrate physical, cognitive and behavioral sides of a userââ¬â¢s interaction with the system. Moreover, PCT analysis of intentions from different user groups exposes their shared narrative, which in turn, helps in finding system requirements for hidden, absent user (Oââ¬â¢Neal, 2012). For example, a customer service representative might use call center software while working to resolve an issue with a customer. While the customer is not a direct user of the software system, he is affected indirectly. The customer here is a hidden user. His perceptions should be analyzed to understand his requirements and objectives while developing the call center system. Empowered designs PCT offers a design framework toward the satisfaction of the users desired percepts. Human-machine system performance is enhanced when the displays and controls are designed to allow the operator to perceive and transmit information in order to minimize the perceptual error (Chery Farrell , 1998). According to PCT, when a user interacts with the system, he is constantly trying to bring equilibrium, changing his perception to the reference point, which is his new perception. Keeping this in mind, a designer should build the system that transforms from an old state to the new state seamlessly, provides estimate of gap between old and new state, furnish necessary feedback to keep the user aware of the environment variables and helps the user to manage disturbances. These functionalities will help users to gain accurate information regarding their perceptions, empower them to undertake correct amount of action to reach to new perception, ultimately helping them achieve self-regulation and stability. For example, the windshield of the car let the user scan his environment and gather information necessary to their perception, the car dashboard continuously displays speed and other important elements to help user assess different system states, and the gear stick helps user achieve n ew state from the old one smoothly. Other features like wiper, headlights, turn signals etc. facilitate users to manage disturbances as much as possible. Thus, human-machine designs should be compatible with userââ¬â¢s interpretations of information in order to improve their decision making process and overall system performance. Conclusion Both human error and PCT frameworks are valuable in building complex system designs to facilitate information management, enhance security and improve both system and human performance. By understanding fundamentals of human errors, designers can build a system that is more usable, provides meaningful feedbacks and include training, procedural checks and incentive programs. However, according to Shelton (1999), there is a trade-off between making the HCI relatively easy and intuitive and ensuring that system safety is not compromised by lulling the operator into a state of complacency. In PCT, the error is continuously measured to achieve equilibrium. Per Lulham (2005), those involved in developing the theory believe PCT has significant potential to change the way human functioning is understood.
