Cognitive Behavior Group Therapy and Yaloms Therapy Model
Table of Contents Theory Group Membership Aims and Objectives Process Structure Conclusion Reference List A number of approaches have been developed by various theorists and psychologists in order to help at managing psychological disorders. Cognitive behavior group therapy and Yalomââ¬â¢s therapy model are considered to be one of the most reliable approaches to evaluate problems within dysfunctional emotions and behaviors. Advertising We will write a custom essay sample on Cognitive Behavior Group Therapy and Yalomââ¬â¢s Therapy Model specifically for you for only $16.05 $11/page Learn More In this paper, these two models will be analyzed and evaluated in terms of their similarities and differences: the essence of Yalomââ¬â¢s model and cognitive behavior group therapy model, their objectives and structures, and group membership. Theory Cognitive behavior group therapy, also known as CBGT, is an approach that is used during the group therapy in order to treat different variants of social phobia. CBGT is one of those models, which can be used in treatment under certain inpatient settings (Christner et al., 2007, p. 509). Yalomââ¬â¢s therapeutic model assumes that interpersonal interaction is essential for the success of group therapy. Yalom himself suggested that change through group therapy is a complicated process that is facilitated by interplay of human experiences, which he considered as the therapeutic factors. The theory of cognitive behavior group therapy is based on the ability to conceptualize information for each member of the group and the group as one whole. It is necessary to identity the problem that causes psychological problems and working on the problem so as find workable solutions based on the problems. This model utilizes the Socratesââ¬â¢ way of knowledge unlike the Yalomââ¬â¢s model because the therapists have a desire to know much about the client using the technique of questioning. It is also based on educational model of doing things with the assumptions that all behaviors and attitudes adopted by individuals are all acquired through learning process (Montgomery, 2002, p. 34). In cognitive behavior group therapy, the goals of the entire process are set in accordance to the existing problems. It is then that thinking behaviors that are at the center of the behavior problem are modified. On the other hand, Yalom based his practice on the importance of therapeutic factors in finding solutions to psychological problems.Advertising Looking for essay on psychology?

Therefore. in terms of theory, the two models are different in their own fundamental principles that guide their functionality to the patients. Group Membership The two models tend to be joined by the fact that b oth of them place much emphasis on the importance and relevance of here and now theory in group therapy. Concerning group membership, I can note that with cognitive behavior group therapy it can be applied to a group of people only. Membership is limited to the one therapist to provide services to a number of clients. This can even be done over computer programs. In cognitive behavior group therapy, emphasis is not put much on the number of members attending the sessions with the therapist. It works because the interaction between the therapist and the patients, and the patient and the patient actually matters in the success of the approach. To a greater extent, cognitive behavior group therapy is a collaborative process between the patients and their therapist. In other terms, if there is no cordial relationship between the two, then the approach cannot work at all (Yalom and Leszcz, 2005, 153). This is unlike the case in the Yalomââ¬â¢s therapy model; whereby the whole thing i s a group affair whereby the larger the numbers the better the clients benefit because they need each otherââ¬â¢s experience so as to find solutions to psychological problems affecting them. Therefore the number of clients attending the sessions in this model really matters to the success of the approach. Yaloms model does not need so much the collaboration between the client and the therapist. In terms of composition of members it is clear that Yalomââ¬â¢s model uses certain criteria in the selection of membership. For instance, exclusion criteria are often used in the selection process (Yalom and Leszcz, 2005, p.153). Inclusion criteria are also adopted in the model, basing on the level of motivation between members. This is unlike the situation in the cognitive behavior model. But overall, both models of behavior change have membership and the involved members, who attend the therapy sessions for them to find solutions to their psychological problems.Advertising We wil l write a custom essay sample on Cognitive Behavior Group Therapy and Yalomââ¬â¢s Therapy Model specifically for you for only $16.05 $11/page Learn More Aims and Objectives Looking at the aims and objectives of both models, it is vital to underscore the fact that both models aim at improving the behavior of the clients through the psychological processes (Callahan, 2004, p.502). They therefore help the client to overcome psychological problems that threaten their existence in the world. Cognitive behavior group therapy model can be looked at to be targeting a patient-therapists communication and patient-patient communication as well in order to help solve psychological problems within the group and provide them with a chance to fight against their social phobia. The Yalomââ¬â¢s model can be considered to be focused on creating a group environment to facilitate sharing of experiences between the clients in order to learn from each others experiences and solve their own psychological problems. Process Structure In terms of process and structure of the models, it is important to point out that Yalomââ¬â¢s model is organized in the way that the groups form the basic structure of the model. The clients with psychological problems are involved in certain group activities for their own benefits. Group participation in this model is greatly enhanced by creating the necessary cognitive structures and further clarification of misconceptions (Callahan, 2004, p.502). However, in this model, group cohesiveness is emphasized because of the benefits, which are inherent to the group members. According to the proponent of this model, cohesiveness is a precondition for the success of the therapy, because it determines the functionality of the other therapeutic factors. Some of them are doomed not to work if this precondition is not adequately addressed. This structure is not the same as that of cognitive behavior group therapy, whereby group c ohesiveness is not a precondition for the success of the therapy. In this approach, the members do not enjoy the love and warmth of the other group members. The sense of belonging and unconditional acceptance in not found in the process of cognitive behavior group therapy because lack of this cohesiveness. In group therapy and Yalomââ¬â¢s model, the clients in groups are likely to reach high levels of self-awareness unlike in the other case. This is through such important techniques like feedback that mainly imparts on the life of others, who are in the same group. This cannot be the same in the cognitive behavior group therapy (Corey 2005, p.461).Advertising Looking for essay on psychology? Let's see if we can help you! Get your first paper with 15% OFF Learn More Furthermore, in Yalomââ¬â¢s model form of therapy, patients are thoroughly questioned and after the one discovers what he needs in life. It enables one understand a reality on issues such as death, this form obesity form according to enable one to understand how freedom and responsibility go hard in hard. Yalom includes one specialist and an individual faced with a problem. One person is thoroughly questioned unlike for CBT where we can have a group of people therapy 6- 10. According to there is no fixed life for an individual. In Yalomââ¬â¢s form of therapy, the individual with a problem is the only one who meets with the therapist unlike for the CBT whereby we can have a group that can consist of six people or more. Another difference is that in Yalomââ¬â¢s model, one is asked questions and the help he gets depends on the evaluation made by the therapist (Corey, 2005, p.153). In terms of process, it is important not to overlook the fact that, in both models, the feedback is provided and is quite essential for the personal development of each client. There is also the issue of giving out to receive in both models in the sense that in Yalomââ¬â¢s model one has to understand the value of giving before having the intrinsic drive to share out experiences with others and at the same time gain from others. In the cognitive behavior model it becomes inevitable for the client to be willing to give out information after a cordial relationship is established with the therapist (Corey, 2005, p. 490). In both models, there is the imparting of information to the clients. This is normally through instructional methods, giving of advice and making suggestions to the clients. In both models, there is evidence of the therapist instilling the aspect of hope in the clients. This is very essential to keep the clients in the process of therapeutic change. Without hope in the process, most clients would fall out before they archive the desired results. In Yalomâ⬠â¢s model, faith is itself a therapeutic process and can facilitate change in the behavior of the client. Conclusion In conclusion, it is important to note that the two models of psychiatry under consideration share things, which are in common and differ in a number of areas as it has already been mentioned. The success of each of them remains attached to the commitment of both the client and the therapist in the process. The interpersonal process within a group has had a considerable impact on me personally. Firstly, I have gained a lot in terms of self-awareness from both the group and even from the outside. From inside the group, I was able to interact with all the group members, and we had a very cordial relationship that facilitated openness to one another. I could not believe hearing what some of my friends were revealing to me. From this interaction, I can say that I have been able to discover more about myself as an individual than I used to be in the past before the thera py. Outside the group, I managed to open up well to inside the group and was able to discover much about my behavior. During the therapy, I was involved in numerous group discussions too much, and it turned out to be very useful to me. These group discussions were very free, and everybody was willing to give out his/her own contribution; such activities were actually too exciting, because as it was necessary, each shared own experiences and emotions (Christner, et al., 2007, p.359). It was very easy to respond to the questions from the group members and ask them more questions that helped to disentangle some mysteries. Through this kind of feedback, it was so easy to find solutions to some of the behavior problems that I had. Another important issue to mention is all about the appearance in the group activities. I can say that my presence in the group was easily noticeable by other group members. Through the processes in the therapy, I also understood better what is actually requir ed in terms of the group process. Now, I better comprehend the issues, which are important for the success of the entire process: they are the composition of the group and proper selection of its members. Now, I am in the better informed position concerning the issue of group organization that should be planned on a high level (Christner, et al., 2007, p. 150) and participation of the members and this have had an impact on my organizational skills. I am also able to form a group in the same setting and help the members go through the process successfully in order to get solutions to their psychological problems. The theory that I have learnt concerning psychological problems was easily applied in my real life situation. By this, I mean that I experienced instances of rising anxiety within me. For instance, when there was an intense argument within the group members concerning an obvious issue. I was feeling anxious and I have gradually been able to manage the anxiety by applying the theories I have learnt toward the end. I never clued with any one in the group and other with me in the result of understanding of own feelings, values, and anxiety. During the group activities, I cannot fail to mention that I managed to express emotions that I have not experienced in the past. For example, there is a group member, who gave out a very strong revelation, and I can tell that I was really feeling for her just because of what she has had to go through. The way, she brought out the story, got into me so much that I was feeling that I was the one going through the same situation. My experience helped me to comprehend one simple idea that has been already suggested by many other scholars: interpersonal-psychodynamic group therapy is considered to be a really powerful means and approach for those, who want to improve own life and get rid of past problems (Callahan, 2004, p.491). In general, I can conclude by noting that the group therapy, I went through, has greatly i mpacted on my life in a very positive way as far as psychological development is concerned. I have achieved self-improvement by means of the process of interaction with both the group members and outside the group. Reference List Billow, R. (2005). Bion Today.

Financial Systems & Auditing Essay Example | Topics and Well Written Essays - 3000 words
Financial Systems & Auditing - Essay Example Ledger stores information needed for preparation of financial statements and final accounts. Books of original entry, also known as prime entry books where transactions are initially recorded, such books include sales journal, sales returns journals, purchases journal, purchase returns journal, cash book and general journal. Accounting or bookkeeping assumes vital and helpful role by creating the information for giving responses to numerous questions confronted by the users of accounting information. It gives information how great or terrible the budgetary state of the business is which products or activities have been productive (Singhvi & Bodhanwala, 2006:262). Bookkeeping is vital for a business entity because of the following reasons: - iii) As the business continues to grow, there is an expanded volume of business results in a huge number of transactions, and no business person is able to remember everything. With the help of accounting records, there is no need to remember various transactions (Demski, 2007:33). Apart from the cash flow statement the other accounts are always set on an accruals basis. This basis of accounting requires that the non-cash transactions be reflected in the financial statements for the period in which their effects are encountered and not in the one in which cash or money is actually received or paid. The accounts are often prepared on a going concern basis. This implies that the accounts are made on the assumption that theà organizationà will continue to operate indefinitely or for the foreseeable future. The business has no intention to curtail their operation significantly. This concept helps a business to get long-term sources of finance or loans. It also shows the financial stability to the shareholders that will affect the prices of stock (Kolitz et al 2009:507). Because of many different ways of applying concepts, each entity must select the approach that gives the most reliable picture of the entity

Principles of Economics Research Paper Example | Topics and Well Written Essays - 1000 words
Principles of Economics - Research Paper Example Based on this research economics is about scarcity and choice. It is assumed that all human beings are rational thinkers hence would always choose to consume products that would give them maximum satisfaction or utility. Mankiw argues that rational people ââ¬Ësystematically and purposefully do the best to achieve objectives given available opportunity.ââ¬â¢ Given a choice among alternatives and with scarce resources, one would evaluate the benefits and costs of consuming an extra unit of a product and would only take a decision only if marginal benefit is greater than marginal cost. In this case, to solve the alcohol abuse problem, one has to consider marginal benefits and marginal costs derived from consuming an extra unit of alcohol and since excessive drinking has more costs than benefits, one would refrain from alcohol. The opportunity cost foregone by choosing to abuse alcohol is too high compared to satisfaction derived; money spent on alcohol can do many other things suc h as feeding the family, education for children, and investments among others. Besides, the person may have health problems thus adding to the costs. By considering all these factors, a rational person would refrain from alcohol abuse. Heyne acknowledges the role played by incentives in directing behavior. For him, rational people usually respond to incentives or are induced to act by them. Assuming alcohol abusers are rational, imposing taxes on alcohol substances would eliminate the problem. This would follow the law of demand which states that other things being constant, if the price of a good increase, the quantity demanded of the good decreases. Taxes have the effect of increasing alcohol prices and this would automatically mean that the abusers would desist from alcohol consumption or cut their consumption. Prescription Drug Effects on Demand and Supply of Other Products and Services Prescription drugs are drugs prescribed by a medical officer to a patient and are regulated b y legislation unlike the over-the-counter drugs which can be old to anyone. If a patient is under prescription drugs, he/she buys the drugs despite the price of the drugs. An increase or decrease in price of the drugs therefore has little or no effect on the quantity demanded by an individual (McCarthy & Schafermeyer, 2007). The drugs are provided by the National Health Insurance and have no close substitutes. The increase in price of the drugs thus affects all the sectors of healthcare industry such as patients and private insurers. Due to increased costs, the private insurers are forced to increase the cost of their services in case they have to offer such drugs and this may lead to low demand for their services. The patients are also required to get medical prescriptions before obtaining the drugs thus the demand for the medicine may be low compared to over-the-counter drugs. Use of prescription drugs also has an effect on demand for other healthcare services such as hospitalizat ion. The prescription drugs also affect supply of generic products as manufacturers have patents to supply the new drugs for some years. Elasticity of Demand and Supply The price elasticity of demanded which is percentage change in quantity demanded over percentage change in price shows consumers responsiveness to price changes. (McKenzie & Lee, 2006). It is an important consideration when analyzing the impact of a shift in supply and in determining if the firm should raise or lower its price. The supply curve is upward sloping showing a positive relationship between price and quantity supplied other things held constant. However, in long-run, those factors do change causing a shift in supply curve. Such factors include; input prices, technology, expectations and number of sellers in the market. For example, an increase in input prices such as labor would lead to a decrease in supply thus shifting the supply curve to the left. This

Global Warming Report Essay Example for Free
Global Warming Report Essay Over the past few decades scientist have been observing a warming trend in the over all temperature of the earth. Although the earth has been known to go through warm and cold periods, it seems that we humans are causing the earth to heat up this time. The greenhouse effect is causing the earth to go through this warming trend that we call global warming. The greenhouse effect is caused when the infrared radiation from the sun is absorbed in atmospheric gasses such as water vapor, carbon dioxide, ozone, and methane. All of these gasses escape slowly from the atmosphere, therefore the heat stays here longer in a short of warm airy blanket. Without the occurrence of the greenhouse effect scientist say that the earths average temperature would be around 30 degrees C. or 50 degrees F. There are many greenhouse gasses that can trap the infrared rays of the sun. Carbon dioxide can be released into the atmosphere in several ways, the bulk of it is produced by car exhaust, deforestation, and the burning of fossil fuels. It is a colorless, odorless, non flammable gas, and it is also the most prominent greenhouse gas in earths atmosphere. CO2 is recycled through the earths atmosphere using the process photosynthesis, which makes most life on earth possible. Another greenhouse gas is methane and it is one of the most common gasses in the universe. methane is colorless odorless gas that is lighter than air and is produced by organic decay. Deposits of methane can usually be found in areas where lots of natural decay takes place, such as swamps, and land fills. Each year we add 350-500 million tons of methane to the atmosphere through mining, raising livestock, rice cultivation, and landfills. In fact a cow can release up to a half pound of methane into the air everyday. Nitrous oxide is another colorless and greenhouse gas, however it does smell sweet. It is mostly used medically because it deadens pain, because of this it is called laughing gas. It is released naturally from oceans and by bacteria is soil. It is important to reduce our emissions because nitrous oxide we release today will still be trapped in the atmosphere 100 years from now. The set of greenhouse gasses are fluorocarbons, that is a general term for any group of synthetic organic compounds that have fluorine and carbon. These can be found in aerosol cans, refrigerators, and air conditioners. When fluorocarbons are released into the atmosphere they breakdown molecules of the earths ozone layer. The effects of global warming are also good for human beings, because it could increase food production. The most important factor in crop production is climate, and global warming would facilitate a better climate for the growth of more crops. It would also create much more space for businesses were there was once ice and harsh climate. Also without global warming the earth temperature would be about 30 degrees F. n average. With global warming there would be far fewer deaths from cold exposer. If global warming caused enough arctic melt then shippers would have many new shortcut routes to take from place to place. After glacier melt we would have access to many new mining areas. However global warming will also have some large negative effects. Such as health concerns, scientist predict that there will be ma ny more deaths from diseases that are irritated by heat, including heart attacks and heatstroke. Another downside to global warming is the amount of flooding that will occur with coastal cities. Scientist have predicted that about a sixth of the country will be under water after global warming has taken full effect. The Maldive Islands are a nation of 1190 islands that are home to over 200,000 people. These islands are only 1. 5 meters above sea level and if global warming occurs then all of those people will have to be relocated. There are many things that we as human beings can do to help prevent global warming from happening. We can start to take advantage of all the different types of renewable energy instead of burning fossil fuels that pollute the atmosphere in multiple ways. There are many types of clean, efficient, renewable energy sources. There are many energy sources that the earth has provided for us that we need to take advantage of. We need to build more wind turbines, hydro electric plants, and solar power plants. Another way of producing clean energy include using fission through nuclear power to create a clean renewable energy source. Government can also be doing there part by funding research about global warming and raising awareness about how individuals can be doing there part to reduce pollution. In conclusion, Global warming is a very serious thing, it can affect the orld in many different ways. We just need to decide which effects help or harm the world the most and then make an educated choice as to which ones the earth can handle while taking the least amount of stress, and having the best long term effect.

Essay example --
Most of Australians are affected by housing loans. 70% of homeowners buy a house in Australian through the housing mortgage loan. Due to the optimistic attitude of the general public about the economic situation, a lot of people buy houses for renting out to obtain stable income. In 2010, the Australian Government authorized the Australian Securities and Investment Commission (ASIC) to regulate exit fees that banks were seeking to impose. The exit fee is the payment that banks require customers to pay for permission to transfer their home loan to another bank, which considers the housing loan being one of the most important factors in exit fees or "terminateâ⬠. In an article of The Times, it was reported that an exit fee of $5,178 was charged if a loan of $300,000 was borrowed for 25 years and terminated within 3 years (Martin, 2010). Such an expensive exit fee makes high switching cost for the house loan takers, through which the bank may gain market forces. This article will discuss the switching costs in Australian home loan market and analyze how these switching costs may increase market forces of suppliers in these markets. In addition, this article tries to find out that after exit fees is changed according to the new regulations, what the changes of supplier cost will be and whether their profits will increase or decrease. Switching costs in Australian home loan market ââ¬Å"Switching costs "was first presented by Michael â⬠¢ Porter in 1980, referring to the one-off cost generated in the course of consumers transferring from one provider to another product or service provider. This cost includes not only economy expenses, but also time, energy and emotion, being an important factor of constituting barriers to enterpri... ...lly, the equilibrium is at point A (Q1, P1). With more rivalry and competition between suppliers, S1L shifts to the rights of S2L. The equilibrium point moves from point A to point B (Q2,P2) . As a result, loans price (interest rates) fall from Q1 to Q2 according to Graph 1. Profit is equal to total revenue of minus cost. While total revenue is equal to the price multiplied by the quantityï ¼Ëprice is decreaseï ¼â°. It can be concluded that the Australian government to develop policies to protect the interests of local people through the intervention of good housing loan market. The Australian government's move to provide a variety of options for Australians, they can freely choose, while reducing the financial risks, the government provides loans to low-income persons through banks at below market rates, and they encourage healthy competition wwithin the home loan market.

I. INTEGRATED SCIENCE(Interaction: Environment and organism) II. COURSE PAPER: CASE STUDY Bacteria constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a wide range of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear onEarth, and are present in most habitats on the planet, growing in soil, water, acidic hot springs, radioactive waste, and deep in the Earthââ¬â¢s crust, as well as in organic matter and the live bodies of plants and animals, providing outstanding examples of mutualism in the digestive tracts of humans, termites and cockroaches. On February 6, 2013, scientists reported that bacteria were found living in the cold and dark in a lake buried a half-mile deep under the ice in Antarctica. There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water; in all, there are approximately five nonillion (5Ãâ"1030) bacteria on Earth, forming a biomass that exceeds that of all plants and animals. Bacteria are vital in recycling nutrients, with many steps in nutrient cycles depending on these organisms, such as the fixation of nitrogen from the atmosphere andputrefaction. In the biological communities surrounding hydrothermal vents and cold seeps, bacteria provide the nutrients needed to sustain life by converting dissolved compounds such as hydrogen sulphide and methane. Most bacteria have not been characterised, and only about half of the phyla of bacteria have species that can be grown in the laboratory. The study of bacteria is known as bacteriology, a branch ofmicrobiology. Most bacteria secrete a covering for themselves which we call a cell wall, However, bacterial cell walls are a totally different thing than the cell walls we talk about plants having. Bacterial cell walls do NOT contain cellulose like plant cell walls do. Bacterial cell walls are made mostly of a chemical called peptidoglycan (made of polypeptides bonded to modified sugars), but the amount and location of the peptidoglycan are different in the two possible types of cell walls, depending on the species of bacterium. Some antibiotics, like penicillin, inhibit the formation of the chemical cross linkages needed to make peptidoglycan. These antibiotics donââ¬â¢t outright kill the bacteria, but just stop them from being able to make more cell wall so they can grow. Thatââ¬â¢s why antibiotics must typically be taken for ten days until the bacteria, unable to grow, die of ââ¬Å"old ageâ⬠. If a person stops taking the antibiotic sooner, any living bacteria could start making peptidoglycan, grow, and reproduce. Bacteria were the most prominent creatures in the early stages of lifeââ¬â¢s history almost 4000 million years until 600 million years ago. Fossils called stromatolites can still be found and were made by Cyanobacteria. III.

CONTENT A. BRIEF PRESENTATION OF THE CASE Endogenous endophthalmitis is a potentially blinding ocular infection resulting from hematogenous spread from a remote primary source. The condition is relatively rare but may become more common as the number of chronically debilitated patients and the use of invasive procedures increase. Many etiologic organisms (gram-positive, gram-negative and fungal) have been reported to cause endogenous endophthalmitis. Risk factors are well defined and include most reasons for immune suppression. A high clinical suspicion is needed for early diagnosis and treatment. Early intravenous antibiotic therapy remains the cornerstone of treatment. The roles of intravitreal antibiotics and vitrectomy are evolving and may become more widely accepted as therapeutic modalities. The authors report a case of endogenous endophthalmitis and provide a brief review of the literature. Endogenous endophthalmitis is defined as an intraocular infection resulting from hematogenous bacterial spread. It is relatively rare, accounting for 2 to 8 percent of all cases of endophthalmitis, and is associated with immunocompromised states, debilitating diseases and invasive procedures.1 Because of the rapid advance of medical technology, a longer life span of patients with chronic diseases and a rising prevalence of long-term intravenous access, the disease may become more common in clinical practice. It is important that the family physician be aware of endogenous endophthalmitis because early diagnosis and prompt aggressive treatment are imperative if vision loss is to be avoided. B. POINT OF VIEW Banana bacterial (Xanthomonas) wilt, first detected in Uganda in 2001, has since spread rapidly. Approximately one third of Ugandaââ¬â¢s banana growing land is now affected by the disease, which renders fruit inedible and ultimately kills the plant. The Ugandan government has been praised for its promptness in attempting to control the spread, but despite these efforts, and the encouraging success of control in some areas, the risk of further spread, both within and beyond Uganda, remains. Strengthening and refining the control effort is now clearly essential, but how should this be done, where are the research priorities, and what action should be taken by Ugandaââ¬â¢s neighbours? In July this year an expert consultation of senior stakeholders from policy, research and disease control, was convened at the UKââ¬â¢s Central Science Laboratory near York. They offered New Agriculturist their points of view on the current status of the disease and the ways forward for control.
