ADHD Analysis Essay -- Psychology

Attention-deficit/hyperactivity disorder (ADHD) is a developmental syndrome of self-control which leads to problems related to attention span, impulse control, and activity level (Barkley). ADHD is considered by the American Psychiatric Association (APA) to be a developmentally inappropriate attention and/or hyperactivity and impulsivity so enveloping and constant as to drastically interfere with the person’s everyday life (Reiff). ADHD is considered a chronic mental disorder that starts early in childhood and follows the individual into adulthood (Connors). The symptoms associated with ADHD usually effect social, educational and occupational functioning throughout multiple settings (Connors). Even though ADHD is considered a widespread mental disorder and had been recognized as a disease for over a decade, many researchers and clinicians still admit that there are many unknown aspects surrounding the disease (Connors). Background: Person: ADHD is on of the most common learning disorders associated with children; the disease explains 30 to 40 percent of all recommendation made to child guidance clinics, pediatric, family and primary care practices (Connors). ADHD is more common in boys than girls, effecting 3-5 percent of the children in the United States (NLM.NIH.gov). Furthermore, this disease additionally accounts for a large portion of referrals in adult treatment (Connors). For the most part those diagnosed with ADHD seemed to have developed the disease through genetic transmission or chemically produced (Wender). Scientists are still in debate about what actually causes ADHD or if the disease can actually be narrowed down to one thing (NIMH.org).

Sociological Theories Essay -- Papers Sociology Class Power Conflict E

Sociological Theories One of the sociological theories is conflict theory. The conflict theory deals with people's level on wealth, or class. The conflict theory says that social change is beneficial, contrary to focuses on social order. In the story of the woman and her children, the conflict theory plays a big role on the situation. Police of higher class are threatening the homeless woman. The conflict theory is a constant struggle of people of higher class over powering people of lower class, or the weaker. The police are trying to over power the woman by telling her to leave. Even though the woman and her children were doing nothing wrong, the police used their power to tell her to leave. Also the people of the area showed their conflict theory by telling the police officers to come. They must have felt embarrassed to have a woman of such lower class to be around them. They used their power of class to have the woman removed from their community. The woman wants to be there because she has no home and it is a good community to be in, but the people look at it as an embarrassment to them because it makes their area look bad for someone of such lower class to be around them. The conflict theory is unique to all other theories because it separates people into categories determined by their wealth and standards. Their status is the element that categorizes them, weather it is class, race, or gender. The conflict theory do not always use class, race, and gender all at once. In this situation race and gender is not a main issue, although gender could be a reason, but it would fall under the feminist theory. This story is mainly dealing with class. Through all this conflict the woman feels over powered and domina... ...one another and how they depend on each other. The last sociological theory is the feminist theory. This theory deals with human life through the experience of a woman. The woman in this situation may have felt proud at first for trying to take care of her children and keeping them in a good area. She was doing all she can to keep her children in good care. But then when the cops came she might have felt upset and independent. She may have felt like the cops didn?t give her a chance to help her children out and get back on her feet. The women in the area may have felt sorry for the homeless woman and saw her as too independent. So they might have wanted to give her help for her and the children by finding a good shelter home for them. The feminist theory is unique from all the other perspectives because it expresses things from a woman?s point of view.

The range of normal resting CO is between 4.2 L per minute and 5.84 L for these subjects. Did average CO increase, decrease, or not change with exercise? increase Discussion 1. What caused the change in HR with exercise? Muscles use more oxygen and  glucose from the blood with increased movement. This produces wastes that decrease blood pH below the normal range causing an increase in heart rate. The heart rate increase delivers blood to the lungs and kidneys more quickly so these organs can remove the wastes from the body. The faster the muscles use energy and create waste, the faster the heart must pump blood. 2. Discuss the effect of venous return and heart rate on exercise EDV. Exercise increases venous return by forcing your body to add and enlarge blood vessels. In addition to circulatory improvements, exercise helps muscles and tissues become conditioned to allow them to overcome the stresses of working out. During exercise, the body demands additional oxygen and requires removal of extra carbon dioxide increasing the heart rate. EDV is increased with exercise 3. What caused the change in ESV volume with exercise? ESV decreases with exercising so that there is less resistance for the blood to flow to increase cardiac output. 4. Why did SV change with exercise? SV increase during exercise because an individuals body needs more oxygen and nourishment that are both received from the pumping of blood. The level of increase of SV is also depends on the type of exercise 5. Discuss the importance of the change in CO with exercise? When the body is in rest cardiac output is lower as the demand in oxygen is low. During exercise heart rate and stroke volume increase which results in an increase in cardiac output 6. Restate your predictions that were correct and give data from your experiment that support them. Restate your predictions that were not correct and correct them, giving supporting data from your experiment that supports your corrections. My prediction were correct Application 1. We measured the stroke volume of the left ventricle. What was the average stroke volume of the right ventricle at rest and after exercise? 69 resting 104 exercising 2. Assume that for one beat, the stroke volume of the left ventricle is greater than that of the right ventricle. Explain why in a normal heart this would be corrected on the next beat. blood would be transferred from your systemic circulation into you pulmonary circulation. Pressures throughout your pulmonary circulation would begin increasing. As soon as small amount of blood is transferred from the systemic to pulmonary circulation, the pressure in the pulmonary veins and left atrium increases a  little. This increases the filling of the left ventricle, and the resulting increase in its end-diastolic volume increases the stroke volume, correcting the problem 3. Explain why elite athletes have a lower than normal heart rate, yet have a higher than normal ability to increase cardiac output. An athlete has a larger stroke volume, which means a greater volume of oxygen is delivered to the body per heartbeat.They usually have larger heart that results in higher cardiac output, as more blood is pumped out with each beat. The raised cardiac output allows the heart to beat more slowly

Cost of equity capital Essay

Introduction The rate of return that is required is employed in evaluating equity and is the least percentage in a year that is gained by investments of a company through the investors. The cost of equity is the rate of return on investments that is required by the shareholders of a company. The paper will discuss the three models which are the dividend growth, the CAPM and the arbitrage pricing theory. This will be in order to determine which one of them is the best for anticipating the rate of return required. It will also discuss the factors that influence the beta of a company in order to determine the cost of equity. The best model for estimating the required rate of return Dividend growth model is the best for estimating the required rate of return of the company because it is simple in terms of calculations. It is not complicated to apply and enables investors to calculate the growth of their stock easily. This model does not require a specialist and accurate decisions are made on time. This model enables the firms that use it to grow in a rate that is stable and their profits grow at the same level with the dividends. This ensures the investors that the company will meet up their compulsions. It is the best because it is constant as shareholders do not receive more dividends when the company increases profits more than expected. It is a way of determining the value of a share with regard to the current value of the dividends that the company expects to achieve in the future. Dividends can be described as the cash flows that are given back to the shareholders. Recommendation to the board of directors I would recommend to the board of directors that the SLP Company should use the dividend growth model because it is not complicated. It is also certain as the investors are given a fixed rate of return enabling the company to grow steadily. The model also has a basis that is logical as the investors are paid dividends according to their shares. It is also predictable and constant and that is why I would recommend it to the board of directors. Ease of use The simplicity of using the Capital Asset Pricing Model is because it has got relatively simple formulae to use. r = rF + ÃŽ ²*(rM – rF) Where r = requisite rate of return of financial assets ÃŽ ² = financial quality beta rF = risk free pace rM = required charge of return of   market portfolio The model also determines the type of index which suites the company market. For instance, if the business owner feels that the Russell 3000 best represents the business, it is necessary to use it since it is available. The model also looks for beta asset values as computed by Google, finance and yahoo finances. The simplicity of the Arbitrage Pricing Theory is the fact that the model is not restrictive in comparison to other pricing models and theories. The ease use of the divided growth is the fact that it is both easy to use and understand. Accuracy The accuracy of the Capital Asset Pricing Model is that it provides accurate and reasonable results.   By use of its formulae correctly and enough data, accuracy is achieved easily. The fact that the Arbitrage Pricing Theory includes more factors, the theory is also considered more accurate in comparison with the Capital Asset Pricing Model. Since the dividends are fixed during payment, the divided growth is also an accurate method. The method also requires reasonable accurate in order to be effective and accurate. Assumption Capital asset pricing model is based on some fundamental assumptions. For instance, it is true that the investors have similar homogeneous beliefs based on returns for they are interested in maximizing returns commencing their investors. Additionally, the assumption that most people access information on the investment opportunities is evenly practical in a market which is perfect. On the asset pricing model, the assumption that systematic risks exist is true for the environment operated in is full of risks from the external and internal sources. The risks do not have an influence on the investment’s rate of returns. Under the dividend growth model, the fact that it is a powerful and simple tool to use its application is also limited to the businesses developing at a rate which is stable. The model also tends to ignore the organizational cycles where the businesses begin and later declines. The cost of equity is an evaluation that is used in analysis which shows the rate of return that an investor requires. This involves the dividends to evaluate them and be able to take the possibility of investing in a firm. The cost of equity (E(rj) is equal to (RRF) plus beta of the security ßj   multiplied by return on market portfolio RM   minus (E(rj)= RRF  + ÃŽ ²j  (RM  Ã¢â‚¬â€œ RRF) For Nike Company the cost of equity is 0.40% + 0.9(6.50% – 0.40%) =5.89 For Sony corporation the cost of equity is 0.40% + 1.60(9.50 – 0.40) = 14.96 For McDonald’s Corporation  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   the cost of equity is 0.40% + 0.40(8.50% -0.40) = 3.64 The company with higher cost of equity is McDonald’s Corporation because it has the lowest figure compared to other companies. This is because the return is too low which indicates that the cost of equity is high. The theory of finance suggests that when the possibility of investing in a company is high the cost of equity also goes high and when the possibility decreases the cost also goes down. Factors Some of the factors that influence a company beta include; the company’s tax exposure, business risk, the kind of management style, financial flexibility, the market conditions and the growth rates. These factors influence the company beta in different ways. The company’s tax exposure affects the company beta in that the debt payment’s tax is deductable. Therefore, if the origination’s tax rate is at a high position, by use of debt as a channel of financing a project for example is attractive for the deductable tax debts protects profits for the taxes. On the business risk, if the organization risk is high, the optimal arrears ratio is lower. The kind of management style lies between aggressive to constructive activities. If the management approach is aggressive, there is room for the company to become firm by the use of vital debts amounts to increase a company’s share hence development. On the other hand, if the management is constructive, it is less disposed to use the debts as a way of increasing profits. Some of the companies that acquire their finances from borrowing and debts among other methods tend to find conflicts associated with these because the growth firm revenues are not proven and are typically unstable. The market conditions are also influential on the company’s beta. For instance, if a firm has got the need to borrow money for a certain project, the fact remains that the bazaar is struggling and the investors tend to limit the access of companies to capital because of issues with, market concerns. This is likely to affect the company negatively. The financial flexibility allows organizations to raise money even in hard times. The higher financially stable a company is, the less the debts and hence fast development. Conclusion The paper has discussed the ease of the three models which include the dividend growth, CAPM and the arbitrage return theory.   It has also discussed into details the accuracy and the reality of each model in order to determine which one is the best for the company. It has shown that the dividend growth model is the best because it is easy for the company and investors to apply and calculate, it is certain and predictable, has logical basis and is constant because an increase in the earnings does not lead to increase in dividends to the investors which is very beneficial to the company. It has also discussed into details the type of factors that influence the beta of the company. The paper has also done calculations to determine the company with the highest cost of equity. It has also discussed the factors that lead to higher beta of the company.

Ecological Services Assignment Example | Topics and Well Written Essays - 500 words

Ecological Services - Assignment Example From this discussion it is clear that ecological services ensure the survival of wildlife by offering habitat. Fresh water and food with nutrients is also brought forth by the ecological services. Ecological services are free but serve very vital functions. For instance wild pollinator services are argued to be six billion dollars annually. However the cost is not incurred since there is pollination by wild pollinators for free. Bear in mind that plants pollinated by wild pollinators constitute a third of the food consumed by humans. Climate is a naturally occurring aspect of the environment which is almost impossible for humans to control. This paper declares that through ecological services, it is possible to enjoy different kinds of weather through the collaboration of water masses and the sun. Water masses, forests, wetlands and estuaries are among the givers of ecological services. For example the occurrence of a forest indicates purified air due to trees giving off oxygen and cool climate due to evaporation by leaves. Ecological services benefit all living organisms in different ways. There are two very vital ecological services from the river. The first is the provision of clean drinking water. This is followed by the provision of habitat for the fish and other aquatic animals within the surrounding. Water is a basic need. It is extremely important for the survival of humans. It is not only needed for drinking but also for cooking and cleaning. It therefore qualifies as one of the most vital ecological service. The fish are provided with habitat by the river which is an important function.

Technological Developments For The Field Of Art And Design Case Study

Technological Developments For The Field Of Art And Design - Case Study Example The different developments in the field of art and design have enhanced the level of designs developed and created more complicated designs that were originally not possible. Considering the different efforts and thoughts that are invested in designing, the complexity of the subject makes it mandatory and challenging for the designers to satisfactorily develop designs that they desire. The development of these designs in a manual manner creates difficulties and errors that may result in poor works and poor designs. It is therefore of vital essence to have technology applied in the field of art and design to create better designs that can have sophisticated compositions that can create a good product that matches the needs of the current technological world. The area of art has for years since its earlier developments relied heavily on bare talent that may not sustain the ideas of the developer for long. The consideration of technology into the field creates an avenue for the designers to feature more in the field and continuously produce products for a longer period without failures. The content of this paper discusses the different approaches that technology has enhanced in the field. Among the many aspects, that the world has had to do away with to pave way for technology is the association of life aspects to culture. Many of the developments and resistance that technology faced during the years was related to cultural associations that originally centered in all aspects from the way we perceive art and the different designs. Embracing culture in all these aspects makes it difficult for technology to develop better results, make the field of art, and design more successful. The resourcefulness of the field has also slowly has transformed the field with other changes that have seen to the development of better designs and more enhanced.

Telemedicine Essay Example | Topics and Well Written Essays - 250 words

Telemedicine - Essay Example In some departments such as I.C.U and mental health, superior product is delivered. There was greater patient satisfaction and outcomes (Moehr et al., 2006). For more than forty years, telemedicine has been instrumental in delivering healthcare services to clients in marginalized geographical area. Telemedicine did not only improve patient access, but  also allowed health facilities and physicians to broaden their reach (Moehr et al., 2006). Since containing or reducing health care cost is a key consideration in operating a healthcare system, telehealth services come in handy. It has been shown that telemedicine increases efficiency and reduces healthcare cost through reduced travel trips, shared staffing of health professionals, better chronic diseases management are reduced hospital stays (Moehr et al., 2006). There was overall satisfaction of using the telemedicine services especially on those trained to use the services. There was faster sharing of information and consultations making even learning better. However, those who did not understand well how to utilize the telemedicine were often frustrated and resorted to the traditional face-to-face method (Lam, 2007). Access to the internet is the first requirement for setting up Telemedicine. Enough bandwidths are required to transmit video and audio data. Rural healthcare organizations may face the challenge of obtaining reliable and affordable broadband service. Imaging technologies and their peripherals are a necessity since they are the crucial part of telemedicine (Merrell & Doarn, 2007). They allow healthcare providers to hearand see patients in faraway places. Devices like digital stethoscopes aid in transmitting lung and heart sounds to a remote provider. Moehr, J. R., Schaafsma, J., Anglin, C., Pantazi, S. V., Grimm, N. A., & Anglin, S. (2006). Success factors for telehealth—a case study. International Journal of Medical
