Botany - Essay Example Fortunately, the precious knowledge about herbal medicines has not been forgotten and currently a number of people are seeking herbal remedies as cures for their numerous ailments. There has been a lot of concern towards the use of herbal medicines. Many medical practitioners tend to argue that these forms of natural medicines could cause harm to the users since they are not medically tested and accepted as the right remedies or cures for certain ailments. Canada has regulated the use of natural remedies by drafting into its constitution the restrictions of administering herbal or natural medicines to the citizens (Green 7). For herbal remedy to be accepted in Canada, the following regulations must be followed. To begin with the remedy must be licensed, the site at which the remedy is being processed must also be licensed, good manufacturing practices must be followed in accordance to the law, the remedy must pass the clinical trials, and finally the side effects of the remedy must be reported (Green 12). As to my opinion, restriction to natural remedies should be there but not that extensive. Most people have deep faith in natural products than in other synthetic drugs. Putting in place extensive restriction on herbal medicines will deny herbalists and those who believe in the power of herbs a chance to express their freedom. Herbal medicines are gaining great popularity in todayââ¬â¢s world as people are trying to reduce the levels of chemical intake. Finally I would like to pose this question to my fellow classmate to answer ââ¬Å"are natural remedies more effective than synthetic drugs? Green, Barry.

The enzyme potato catalase Essay Example for Free
The enzyme potato catalase Essay Analysis Instead of filtering out poor data for my results I have decided to select the best result to concentrate on. I removed quite a few results. The reasons for removing results was either because of missing data, anomalous data (not following the trend of others that I believed to be correct), and unusual entries such as amount of oxygen collected decreasing as the experiment went on. This most likely was because of inaccurate readings as other explanations, such as the oxygen dissolving in the water, are unlikely. These are the result I have chosen: The effect of hydrogen peroxide (substrate) concentration upon the rate of oxygen production in the presence of Catalase Concentration of Hydrogen Peroxide (vol) Volume of gas collected in inverted measuring cylinder at end of each successive minute (cm3) over a period of 4 minutes Student InitialsThis is an example of one of the results I did not include: From my selected results I also split them into the 4 different concentrations of hydrogen peroxide tested for ease of use which went as follows:5cm2 10cm2 1 Minute 2 Minutes 3 Minutes 4 Minutes 1 Minutes 2 Minutes 3 Minutes 4 Minutes Minutes 2 Minutes 3 Minutes 4 Minutes 1 Minutes 2 Minutes 3 Minutes 4 Minutes 1I did not include this as some information is missing, possible implying that the way in which the experiment was performed was faulty. This could lead me to a false conclusion. This is another example of the type of results I did not include:à As you can see the amount of oxygen collected has decreased throughout the experiment, this is very unusual, and likely suggests that the readings were incorrectly read, for this reason I do not want inaccurate data to lead me to a poor conclusion.

After selecting my results, I have taken the mean of the selecting results, it is as follows: Concentration/Time This graph shows that as the concentration of hydrogen peroxide increases so does the amount of oxygen produced. It increases at roughly the same rate throughout the reaction and the amount of oxygen produced is generally a higher amount with a higher concentration. This half matchs with my hypothesis, I predicted that the reaction would start to slow down after the initial reaction had occurred, this does not however seem to be the case. However, the initial rate of reaction is a lot higher The possible reasons for this could be that the reaction did not have enough time to start to level off or slow down as there was still a lot of substrate left over and the reaction could still be performed at maximum rate, if this was the case it would not start to slow down until there was significantly less substrate available, obviously this has not been the case. These results do match my hypothesis in that I said as concentration increased, so would the amount of oxygen produced and the rate of reaction would generally be greater. Here is a graph to show the initial rate of reaction for different concentrations of hydrogen peroxide As you can see, as the concentration increases, so does the initial rate of reaction, this is because a greater amount of hydrogen peroxide is available, which means more substrate molecules come in contact with the enzymes (and thus their active site) and can be separated into their products, this is explained simply by collision theory in the introduction. The reason that later on in the reaction the rate of the reaction may be different is because there is likely to be less substrate left over as the reactions occurring would have separated them into their products, hence the reaction rate would not be going as fast.

The Study Of Female Deviance Criminology Essay
The Study Of Female Deviance Criminology Essay Living in a period which had totally ignored women and the study of female deviance (prior to 1960s), Professor Frances Heidensohn saw, as other criminologists, the immediate need for research and study on the deviant woman. As a pioneer of feminist perspectives in criminology, Heidensohns work provided the too much mans land of criminology and how women have been unfairly treated and neglected in previous studies. Heidensohn is considered to be a revolutionist in this field of criminology due to her pre-feminist work (Heidensohn 1968 and 1970) on the invisibleness and silence surrounding the female offenderà [ii]à .Throughout her work and extensive research on a variety of different writers and criminologists, she stressed the lack of attention on gender dimensions and the tendency to over-sexualise women crimes. Clearly upset of this status quo, she pointed out also the necessity of taking into account autobiographical experiences of female offenders, who are the actual objects of this study. Frances Heidensohn; a professor in the Department of Sociology at London School of Economics, by her investigation on the study of gender in the context of crime, could be said to have set the foundations for next generations studies on feminist perspectives in criminology. Her biggest question mark was why the chapter of women and crime has been buried for such a long time and why there has been a failure to examine such an important issue. Most of her books and articles try to provide adequate aetiologies to all these question marks. Fortunately, things changed since the 1960s and feminism criminology was developed. As Heidensohn suggested in a metaphorical way, Like a wardrobe of new exciting clothes, a whole treasure generated in criminology. It offers us a great deal more to enrich our knowledge of women and crime. But there is much more on offer too.à [iii]à In other words, Professor Heidensohn held that even thought feminist criminology has been developed there are still many gaps and much more to be done. Thus, Heidensohn illuminated the path towards the understanding of female criminology. In the field of criminological study and most sociological research and writing, analyses of criminal women cannot be found before the 1960s. But even where they are considered, they are subject to marginalising and distorting treatment as Oakley noted in 1982à [iv]à or similarly as Klein suggested female criminality has often ended up as footnote to works on men that purport to be works on criminality in generalà [v]à . This lack of interest was really surprising in Heidensohns eyes.à [vi]à As Frances Heidensohn noted in an important early article on deviance, virtually no serious scholarship has been undertaken to explain the dramatic difference between male and female lawbreaking.à [vii]à Hence, this status quo, which was much more due to male dominance, impelled her to start an extensive research on the subject to provide sufficient answers to all these questions raised. What was central to her work was the amnesia and neglect of women in previous studies in crimi nology and the fact that even where women were recognised, they were depicted in terms of stereotypes and based on their supposed biological and psychological natureà [viii]à . Her major argument which she highlights in all of her books, articles is the necessity of exploring gender in terms of understanding crime. Her discussion was concerned with personal experiences and autobiographies of women offenders in relation to the courts, the law and the police. She strongly stressed that at all levels women have been treated differently than men and in some cases harsher. Under the provisions of criminal law, women are theoretically equal to men. Conversely, she underlined that in many cases the laws on prostitution, for instance, prejudice against women and in general there is tendency to over-sexualise female crime. Frances Heidensohn objected this attitude towards female crime. Prostitution was seen only as sexual deviance and not as the rational choice for some women who need the financial support for themselves and their children (Heidensohn, 1968, p.168)à [ix]à . Klein also shared this opinion. Furthermore, criminal laws and lawyers tended to apply stereotype notions of what a proper woman is and does and dual assumptions such as virgin and whore were made when dealing with female offende rs. Yet, Heidensohn did not criticise that and she recognised that one cannot divorce the law and lawyer from the society in which they operate with its enormous cultural heritage and traditionsà [x]à .Although she did argue about the too much mens world that existed, truly annoyed by the domination of men in administration as well as in the draft of legislation because of the implications that had on female offenders. Further, the courts even though women committed fewer and less serious crimes than men, were often harsher with women. According to Frances Heidensohn, there were several reasons that explained this stance by the courts. One of the strongest arguments that she made was that female criminals were considered to be doubly-deviant. Women criminals were very rare phenomena, a fact that biased the behaviour of the courts towards them. As Heidensohn had pointed out in one of her earliest presumptions, Women defendants therefore seem stranger and thus less comprehensible than men: they offend both against societys behavioural rules about property, drinking, or violence and also against the most fundamental norms which govern sex-role behaviourà [xi]à (Heidensohn, 1970, p.134). In other words, if they had been morally wrong, then they will be punished more; Courts and other agencies treat women as deviant twice over: they have broken criminal law and social expectations of proper female behaviour.à [xii]à In addition, the whole court procedure is something particularly bewildering, alien and unfair to female offenders.à [xiii]à While doing her research, Frances Heidensohn gave a great emphasis on the stereotype notions and the social standards that the society held for criminal women. In patriarchal societies, women were perceived as a source of disorder. Moral values and accepted social standards, especially in previous periods of time, rendered women subject to stricter rules. Moreover, the witch image as well as that of the whore seemed to be the key portrayals of the deviant women. The stereotype of witchcraft, which has always been linked to women, gave the idea of deviant women as especially evil, depraved and monstrousà [xiv]à . On the other hand, the tendency to sexualise the female offences portrayed them as whores. Professor Heidensohn argued that no such notions exist, equivalent to male deviants. On the contrary, male deviants either receive public approval-boys will be boys,- or are at least more positively portrayedà [xv]à . She continued her argument and she strongly criticized the ro le the media had overplayed in forming these ideas; male offenders in novels, films were presented as heroes, something that affected the public reaction and opinion. In reviewing traditional criminology and classical criminological writers, Heidensohn observed that female criminality was determined by their biology and psychology. Lombroso; the father of criminology, and Ferreros research, which focused on the meditation of the skulls, bones and appearance of female criminals, came to the conclusion that women deviants could be recognised by their physical appearance and they had very similar characteristics to male deviants. Women criminals like their masculine counterparts, had certain allegedly atavistic features, notably unfeminine features and built and dark masculine hair.à [xvi]à Additionally, they claimed that criminal women are abnormal. Following these lines, Professor Heidensohn found herself contrary to this presumption. She argued that his analysis of photographs of fallen women is as objective as adjudication in a beauty contest.à [xvii]à Furthermore, Lombroso and Ferreros theories did not provide us an adequate and precise understanding of female crime.What they did show us was the attempt to rationalise and justify the status quo, the existing position of women and the double standard of morals of their day.à [xviii]à Thus they did not draw away from the stereotype notions and the dual assumptions about women (good or bad, normal or abnormal). Deviant Womens experiences was a central method used by Frances Heidensohn and feminist writers towards the understanding of female delinquency; concentration on the researched and their experiences. Even though this methodology received much criticism (Ramazanoglu and Holland 2002)à [xix]à , Heidensohn and Gelsthorpe argued that close reading of feminist discussions ultimately reveal no fixed absolutes beyond the need for sensitivity in the research task, for personal reflexivity and commitment to make the research relevant to women.à [xx]à This methodology vested women the right to speak for themselves, their experiences, their feelings and thoughts. The technique of viewing the world through womens eyes was successful in making women visible in criminology and additionally created awomens world too. The concentration on womens experiences led to some crucial developments in female criminology and feminist contributions to criminology. Feminism standpoitism as Harding puts it (1987)à [xxi]à reflected the concept of viewing the world through womens eyes and encouraged both theoretical and personal reflexivity in relation to knowledge and the process of knowledge production through research.à [xxii]à However, the key aspect of focusing on the experiences of female criminals was that it rendered gender as the basis of understanding and interpreting crime and social conduct rather than simply as a statistical variable. As a synopsis of her study, Frances Heidensohn argued that what seems to be needed in the study of female deviance is a crash programme of research which telescopes decades of comparable studies of males.à [xxiii]à Also, she was consistent with what Mannheim recommended, who held that an objective and scientific approach should try to treat female crime as a topic in its own right.à [xxiv]à She therefore concluded in her book on Women and Crime that in order to gain understanding on women and crime other analyses such as family life, position and social control of women, male dominance should be taken into account. Arguably, she supported that this could not be achieved through feminist criminology or sociology of deviance.à [xxv]à Frances Heidensohns observations have not been subject to too much criticism as Lombrosos or other criminologists theories. However, some points that she did make were subject to debate and disapproval. Allison Morris was one of those who contravened with some of her presumptions. Her enantiosis was basically on the fact that the criminal justice system is a peculiarly alien an unfamiliar worldà [xxvi]à only for women. Morrison focused on the belief that criminal law is sexist in the treatment of deviant girls and women and she went on to say that such factors as race, family circumstances and commitments, types of offence and previous record all clearly mediate the treatment of both female and male defendants and may be that some of those factors are as important as gender, if not more so.à [xxvii]à Indeed, Heidensohn relied on this assumption; that sex is the most crucial aspect and that it is not only women who are being deprived in the criminal justice system. However, wh at Morrison strongly argued was Heidensohns failure to identify other groups of people who could be treated unfairly under the criminal system or the court could be biased against them and to whom the whole process might be unfamiliar and alien. Such groups of people, as Morris suggests could be for young black and working -class men or minorities.à [xxviii]à Finally, she pointed out that it is wrong to present womens experiences in the criminal justice system as a unitary experience. We know that black women are over-represented in our prisons. We need to be able to account for this.à [xxix]à In my personal opinion Morrison made a full disclosure of the reality; that minorities or black people or people of different social standards, could also be treated unfairly in court or could be subject to discriminatory wrongs. She made a very strong argument which did take into account and tried to defend other social and powerless groups and not only women, something that Heidensoh n failed to do. Moreover, that could be the basis for other perceptions that Heidensohn provided. This is the one of economic rationality or that of stigma. Consequently it is not only women who can be motivated by the economic needs to commit a crime; people of a lower class can commit crimes as a result of poverty; or it is not only women who fear the idea of being stigmatised by their offences. Carlen Pat also argued at this part that this stance could cause race or class conflicts. Finally, in general Carlen suggested that no feminism theory could offer aetiologies to three major issues concerning female delinquency; that womens crimes are in the main, the crimes of the powerless; that women in prison are disproportionately from ethic minority groups; and that a majority of women in prison have been in poverty for the greater part of their lives.à [xxx]à Synoptically, Frances Heidensohns contribution to criminology was enormous in relation to female offenders. It could be said as having two sides of a coin. Her research in conjunction with that of other feminist criminologists illuminated the path towards the understanding of the female deviance. However, even though they shed some light on it there are still some dark aspects. As Frances Heidensohn pointed out, the study of female deviance has still a long way to go. The most crucial drawback that I can identify in her work was the lack of consideration of other factors that could play a valid role in the field of understanding crime such as race, class, nationality, age and other social characteristics rather than only focusing on gender dimensions and giving privileges only to women.

What Is The Role Of Engineers?
What Is The Role Of Engineers? Through the last few decades the physical growth of population has become one of the worlds highest environmental threats. This growth has created remarkable demands for land, transportation, energy, water, sanitation, etc., and marked the different areas or fields where engineers are working. As a result, todays engineers in both developed and developing countries must to adopt a new holistic approach toward natural and social systems (Amadei 2004). Which means switch the controlling nature approach for cooperating nature approach; through sustainable development in practice. Engineers, people that design professional solutions for social issues, are playing a vital role in the construction of modern societies, although the ways as they overcome and approach these depend largely on the socioeconomic conditions which vary significantly. This essay will discuss the role of engineers in developing nations and analyse water supply sanitation and energy as two of the most significant ar eas affected by their decision-making. Role of engineering General Perspective The role of engineering has suffered many changes over the last few decades, although its concept which is based on trial and error has remained an essential element of the scientific-technological method; where social, environmental and human factors define the most suitable solution to manage a particular issue. Thus, engineers role is continuing reshaped according to the new challenges and necessities implicated by specialized disciplines on particular areas of technology (civil, chemical, agricultural, etc.). (UNESCO 2010, p. 24) Contemporary Perspective and sustainable development Unlike the 20th century where the engineering era seemed to have unlimited natural sources, todays century is facing serious problems that are putting enormous pressure on the environment (Azapagic, Perdan Clift 2004, pp. 3-5). Therefore, todays engineers besides the basic technical and scientific knowledge of the engineering discipline, they also have to contribute and promote sustainable development that meets todays necessities without affecting adversely the capability of upcoming generations to meet up their own necessitates. This new role of engineering, demands new practices based on social-environmental factors rather than just business goals. Impact of engineering on society The history shows numerous examples in which engineers performance has widely influenced among communities. Quality of life, economic wealth and good infrastructure for instance, are one of the most relevant and common indicators of their weight on society. As (UNESCO 2010, p. 40) have stated, by 2025, the worlds population will have increased from 1.5 billion to 6.6 billion approximately and the percentage of migration to urban areas will rise from 40 per cent to 60 per cent. This information shows that urbanization rates will boost dramatically. Subsequently engineers have the responsibility to make effective and sustainable solutions as an integrated approach without generate negative impacts, which is known as engineering social responsibility. Ethical side of engineering In general terms, engineerings ethics is directly related with engineering responsibilities regulated by standards codes which act according to several situations. The objective of the ethical factor in engineering rather than just fixed up rules, is drawing solutions with reflexion of particular situations fixed into prior principles. On this basis, at the time of making decisions, engineers should take into account the following points: sustainable development, protection of the public-environment, faithful agent of stakeholders related with objectivity, competence-knowledge, fairness and justice, integrity in the workplace (dedication and service), and professional accountability- leadership. (UNESCO 2010, p. 190) Engineers in Developing Countries As in developed nations, engineers must work within the social, economic and environmental context in order to guarantee real sustainable development for the whole world (Parsons 1996, p. 170). Social responsibilities such as water supply, sanitation, food, energy and environmental protection are the same in developing countries. The difference resides on the socio-economic factors which are directly influenced by peoples behaviour, governments positions and development priorities. Engineering skills and ethics in Developing nations As is described in the section A.1 and A.3, competences and principles of engineers in developing countries remain the same as standardized characteristics. The great challenge for them is in fact, to develop realistic projects on time to particular communities and technology available (Parsons 1996, p. 170). In fact, environmental issues, often take less importance because there are others which have more relevant social impact, oil explorations for instance. Successful and failed projects The successful and failed projects in developing countries depends much on the capability of engineers to undertake projects with a clear understanding of the objectives, reliable assessment of resources availability, business, and technical requirements and effective communication among stakeholders. The ability to implement accurately these facts will bring up useful and applicable alternatives to address real issues. By contrast, lack of attention to the social-economic context, ethics codes, unrealistic expectations, underestimated time, quality and cost will bring poor outcomes. (Parsons 1996, pp. 171,172) Relationship between technology and socioeconomic factor The use of high-technology does not guarantee a successful project or accurate solutions. In order to achieve good results, engineers must be able to make a balance between use of technology and socioeconomic attributes. Parsons (1996) points out that the appropriated selection of technology will determine not only projects success also its viability. As a result, there are four points to choose appropriated technology according to socioeconomic factors: it must be conceptual and physically compatible with operators, spare parts and equipment must be available in the influenced area, project funding must be commensurate with its budget, and the technology must be compatible with the physical environment where it will be used. This model leads to concluded that the relationship between technology and socieconomic factor is very narrow, it must fit users and needs as well as must be designed to improve quality life. Engineering Areas Environmental trends that are shaping new engineers Brief mention of important events that encourage environmental view on engineering World population, followed by climate change are considered the two main factors that are shaping new engineers with environmental approach. During the last half of the 21th century; world population increased from 2.5 billion to 6 billion especially in less economically developed countries, this trend is expected to peak at 9.3 billion by 2050 (United Nations 2012). In addition, overpopulation also has been linked with higher demands of natural resources (water, cropland, forest), shanty settlements, transportation-infrastructure deficits etc. Another important event that is making an environmental approach is the fact that the current global economic is based on productivity, which has brought several impacts associated with greenhouse gases, waste product of fossil fuels and air pollution. Climate change is certainly the result of all these elements at an abnormal rate. Thus, the world has changed its development approach to sustainable development (Brown, Rener Halweil 2000). He nce, most of professional corporations have incorporated sustainable development into their aim statements and codes. New model of learning and practice To confront the global challenges that the earth are facing today, engineering education has incorporated the concept of sustainability into all engineering fields. This means, that professional are expected to make reliable decisions that improve quality of life as well as reducing negative impacts on environment and levels of consumption, and planning their actions according to socio-economic factors and technology available. Consequently, the process of learning and practice has been adjusted by a model of education more realistic-practical. Where students throughout workshops are learning and building knowledge in real situations, as well as has created in them greater environmental responsibility. (Amadei 2004). Sustainability and transformation As explain Azapagic, Perdan Clift (2004), there are certainly three constrains that built the concept of sustainability. Techno-centric concerns, which represent human expertise, ingenuity and economic systems, Eco-centric concerns related with natural resources and ecological capability and socio-centric concern based on human and social expectations. The Techno-centric concerns, has been traditionally used in the process of education in engineering, the responsibility of todays engineers is to include in equal proportion or balance all three constraints to achieve a sustainable development. Which ultimately is seeking for human wellbeing, in other words satisfying human needs, improving quality of life in an eco-friendly way. Water Supply and Sanitation Developing Nations background UNESCO (2010) states that water supply is one of the most serious problems facing by developing nations, in India for instance, 85% of the urban population has access to drinking water, but only 20% of the of this meets the health-quality standards set by World Health Organization. Additionally, the daily rate of water supply often is very low and depends on economic factors and location. The situation on sanitation is even worse; often sanitation has lower priority than water supply. It has estimated that 2.6 billion people do not have properly or existing sanitation system in developing countries. Another issue related with sanitation is in fact that wastewater and solid waste collection services; and stormwater drainage are inadequate. Littering directly to open areas for instance, has created environmental impacts on surface and ground water resources being more dramatic in areas such as shanty towns. Engineering Challenges Engineers approach The traditionally treatment of water supply and sanitation management is considered now as a standard procedure. Which has several treatments according to the water physicochemical characteristics, technology available and environmental regulations. Although, it is by no means certain that this procedure has been the best. Indeed, 95% of the wastewater in the world has been discharged to the environment without treatment (Montgomery Elimelech 2007). Hence, Beside new regulations and codes, todays engineers rather that replicate solutions from developed countries to developing countries, they will have to meet basic needs of all communities for water and sanitation and work as facilitators of sustainability approach within context institutional, social, political, economic, environmental and technological. Thereby, the issue of water and sanitation in developing countries will be overcame or at least reduced. For example, cleaner production can be an expensive solution, however it is really depends on numerous conditions linked with the population objet, such as natural resources, requirements and social class. Energy Developing Nations background In the next few decades, the pressure on energy services will increase considerably in developing nations. It is predicted that energy consumption worldwide will increase about 30% from 2007 to 2030 and most of that growth will be came from developing nations. As a result, the intergovernmental panel climate change (2007) point out that these energy issues will be addressed through cost-effective energy programs based on the reduction of fossil fuel use; implementations of ecofriendly technologies and renewable energy in housing, transportation and industrial sectors and finally the reduction of life-cycle cost, this related with all expenses in the design, construction, operation and maintenance of a particular project. (Liu, Meyer Hogan 2010, pp. 35,36). Todays modern development demands serious energetic programs that fix up both economic development and sustainable development based on the rational use of natural resources. Engineering Challenges and approach in developing Nations. Worldwide experiences have showed that the replacement of non-renewable to renewable energy seems to be more expensive and moreover, information about renewable technologies is inadequate or unreachable. For that reason, the common commitment for engineers on energy solutions is provide better alternatives in terms of sustainability and development. Adoption and design of new technologies, regulations, engineering supervision within national strategies, continues updating, provide advice of energy requirements, etc., will be the common areas where engineers role will be crucial for environmental energy development in the less economically developed nations. (UNESCO 2010, p. 288). Levineââ¬â¢s Conservation Model Theory: Case Study Levineââ¬â¢s Conservation Model Theory: Case Study According to Rafieian-Kopaei, Setorisi, Doudi, Baradaran, Nasri (2014) atherosclerosis is a result of hyperlipidemia and oxidation, and it has been a principal factor of mortality in developed countries. Atherosclerosis is a common disease where fatty deposits called atheromatuos plaques develop in the inner layers of arteries. This process begins with a deposition of small cholesterol crystals in the intima, so the plaque grows, and inflammation process develops in the same time, which results in the fibrous tissues development. As a result this process, clot formation and thrombosis are developed, which conclude in blood obstruction and consequently in heart deficit and other factors dependent of the place where it is affected. In the same aspects, Strain, Hughes, Mayet, Wright, Kooner, Chaturvedi, Shore (2013) had described that some consequences related to atherosclerosis such as hypertension and ischemic heart disease, so these are two main disease, which can be developed in t he process of atherosclerosis. Besides, Levine (1973) in her nursing theory has introduced the theory of conservation model where holism is a key factor in the process to care and manage a client. Throughout the course of this paper, I will describe a clientââ¬â¢s history, a concise introduction about the Conservation Model theory, the application of this nursing theory for the client, and a response plan with a chronic care model, which can be applied for this client. Firstly, the clientââ¬â¢s history is necessary to know and understand, so the caregiver and health professional can develop methods, which facilitate the life this person. The patient V.D has described part of his history in the following information. Mr. D., 47 years old, married, has not concluded elementary school, is atheist, and is a farmer. In his family history, he described that his parents had died because of heart complications, but he did not know the exact cause. Mr. D. had been submitted to stent implantation where exams had proved the diagnoses of coronary artery disease. After six months, he was submitted to bypass surgery. Even though a focus hemorrhagic had developed, Mr. D. was resubmitted to another intervention surgery, in the same day, to control this hemorrhagic area. Also, before the discharge, Mr. D. has received simple explanations about how to proceed in the recovery time; these explanations were about medication (teaching correct administration time and dose), caring about the dressing in the surgical site, and orientation to return to visit the physician in 60 days to have a revaluation about the general recovery and surgical site. The general knowledge to have adaptation was provided by Mr. D.ââ¬â¢s family and friends, whom tried to provide better quality of life in this crucial moment of recovery and adaption for a new life style. In addition, some key chronicity concepts can be understood in the clientââ¬â¢s history. Related to Kramer-Kile, Osuji, Larsen, Lubkin, (2014) these chronicity concepts are: 1- illness experience, Mr. D. was diagnosed with atherosclerosis a short period before to be submitted to surgery, so he had develop d method to adapt to symptoms of this disease when he was developing his daily activities; 2- stigma, it is related to the cultural background and level of education, so Mr. D. has restriction in his level of education so that it can promote an increase in the level of stigma; 3- adaptation and quality of life, during and after recovery, it promotes a drastic process to adapt in this new style of life because Mr. D. has experienced a new process (illness) in his life and his job (farmer) must be substituted, so he could have a adequate adaptation and quality of life; 4- sexuality, Mr. D has a cardiac disease and did a bypass surgery, so it must have affected his sexual activity; and, 5- self-care, as a farmer and has cardiac disease, Mr. D. must control his activities to provide better care and management for his life because the opposite side it develops worse affects. In fact, chronic concepts are present in all process of the illness, so it needs to adequate for the person. Likewise, nursing theories are used to promote better care and the same time knowledge about the general process to manage the quality of life. As a result, the theory Conservation Model by Myra Levine describes the conservation model, which was originally a framework to teach undergraduate nursing student (Levine, 1973). The three major concepts for the conservation model are: first, conservation, which is maintaining together of the life system (balance between nursing interventions and client participation). Second, adaptation, which means an ongoing process of change, but the individual keeps his/her integrity within realities of his/her environment. Third, wholeness is existent when interactions or constant adaptations to the environment permit assurance of integrity (Alligood, 2010). This theory has conservational principles as energy conservation, structural integrity, personal integrity, and social integrity (Levine, 1973). Still, in this theory, the metaparadigm concepts are the person, environment, health, and nursing. People are holistic beings who are sensitive, thinking, future-oriented, and cognizant. Though, people are in constant interaction with the environment, responding to change in an orderly, sequential pattern, adapting to forces that form and reform their essence. In fact, the goal of client care is promotion of adaptation and well-being (Alligood, 2010). These factors are reinforced by Levine (1973) that the process of client understanding his/her plan of care and diagnosis is vital. This theory reinforces the importance of the nurse holistic view during the nursing process to make a plan for the client. Then, the Conservation Model Theory is applicable for Mr. D. in his process of disease and illness, so a nursing theory is applied to promote better process of care and quality of life. According to Alligood (2010) the Levineââ¬â¢s Conservation Model is applied in three main areas such as conservation, adaptation, and wholeness. In the aspect referent to conservation describes the conservation of energy, so Mr.D. must have restriction in his life to keep adequate levels of energy although he continues doing daily activities. For example, he is a farmer, so he needs to understand that some activities in the farming he cannot do because it will require high levels of activities. If he stops doing activities, he has a possibility to develop other factors, which decrease his quality of life. Also, farming requires different activities with lot of energy, but it is not a factor to leave these activities. A management in the process to work can be favorable, and working in small process es results in the job concluded and the body in action. In addition, the adaptation is a rouge aspect present after the surgery, so it requires time and motivation from the client. In this process client, family, first caregiver, and health professional are involved in this process of adjustment. Though nurses have a crucial function for the client, which is teaching and doing management to provide better quality of life. Kramer-Kile et al (2014) emphasise the psychological and social result of chronic diseases require significant adaptations from the client. Consequently, Mr. D. has significant changes in his life such as alimentation, medication regimen, and daily activities (working). Through alimentation is not considered an important factor for some society, it has a key for the prevention and promotion of atherosclerosis. The unhealthy diet where has food with high quantity of saturated and fats, cholesterol levels, sodium and sugar can increase development of atherosclerosis. The unhealthy blood cholesterol and lipoproteins levels promote an increase in the atheroma, so the process of occlusion of lumen is increased; triglycerides is other factor to increase the occurrence of atherosclerosis. Also, overweight or obesity contributes extremely in this process because the level of exercises is totally reduced and weight gain is increased. Rafieian-Kopaei et al (2014) Mr.D. must need an adaptation in the alimentation where alimentary factors can be controlled and managed to develop a health alimentation. Moreover, the medication regimen and daily activities develop a reorganization in the routine. In the medication regimen a different types of medications are necessary to be taken, so a correct management of drug is necessary, so drug interaction will not result. Side effects can occur, so as a nurse must teaching the client about this process and emphasize for the client continuing the medication although he has this process. Even though medication regimen is prescribed by the doctor, nurse needs to verify if the patient understood and/or is taking correct. Furthermore, daily activities must be reformulated because Mr. D. cannot continue doing high levels of effort. Hence, client, family, and health professional must work together to develop an adequate management, which provides easily and comfortable adaptation. Still, wholeness is a part of all these processes because the client and environment interactions to provide changes occurs in the same time that adaptation and conservation. The process of interaction with the environment is crucial whenever the human being interact with the environment and contrariwise, so both sides receive affects to increase or decrease life. As a result, conservation of energy and adaptation work in the same time with wholeness, and the quality of interaction must be satisfactory for client. In the nursing process ââ¬â assessment ââ¬â the nurse and client will analyze challenges in the clientââ¬â¢s environment and methods to be adequate in this system. Some aspects are necessary to observe in this process such as energy conservation (balance between energy supply and demand), structural integrity (the system defense of the body), personal integrity (clientââ¬â¢s dignity and personhood), and social integrity (clientââ¬â¢s involvement in the society or his community) (Alligood, 2010). Instead, in this process of assessment, the word holism is a fundamental definition in the general process to assess the client. As a result, looking for a short-long future some challenges can be observed, so it has great opportunity to change and develop other managements (Levine, 1973). Another example in the Mr. D. progress of illness is that his disease can be linked by genetic factor because as a described his parents had cardiac problems. Thus, his offspring has an inc rease possibility to develop cardiac problems in the life progress although it can be controlled by intervention such as educational factors, alimentation, exercises, and level of stress. Shalhoub, Sikkel, Davies, Vorkas, Want, Davies (2014) reinforce in a research about biologic factors of atherosclerosis that a person who has someone in the family (first lineage) has a genetic risk factors for susceptibility to develop atherosclerosis. Although a variant in the genetic and environmental factors can be present, genetic is an important factor-development to be considered. Likewise, Mr. D. needs to have orientation for other cardiac diseases, which develop in response of a first disease. In this progress, hypertension is a factor to be considered, so prevention and promotion are the basis in this progress. An adequate quantity of sodium by day is necessary, so teaching and explanation about it needs to be done (Rafieian-Kopaei et al, 2014). Consequently, a holistic view is necessary to understand the progress of disease and illness, so management in prevention and promotion are developed in conjunct with health professional and client. Another process in the theory is hypotheses, more specific goals, the nurse seeks validation with the patient about his/her problem, so the nurse hypothesizes about the problem and its solution, which means the plan of care for the patient (Alligood, 2010). In order that, Mr. D. has some hypotheses for his situation such as risk for infection, deficit of knowledge in his process of care (post-surgical), inadequate cardiac output, acute pain, and, risk for compromised resilience (Ackley Ladwig, 2014).After hypothesize clientââ¬â¢s factors, it is necessary to develop intervention, which can develop to acquire the goals settled. The interventions are hypothesis to direct care the client. It is based on the conservation principles: conservation of energy, structural integrity, personal integrity, and social integrity; the goal is to maintain wholeness and promote adjustment for the client (Alligood, 2010). In this case, Mr. D. has broad interventions in his case, which begins in the self-care to social involvement. The surgical wound he needs to have information about how caring it. The nurse needs to teach about cleaning and changing dressing though some indications of infections in the surgical wound, so he can contact his doctor and/or nurse to verify this process. Medications to control and relieve pain are necessary to know, so teaching about it is fundamental. Although he has different type of cardiac medications, he needs to know all of them besides analgesics and nitroglycerine drug for angina if he develops coronary spam. Nevertheless, nurse helps in develop plans for the process of adaptation, which must be approved and oriented by Mr. D. This time for adaptation involves his recovery and after that for the process working in the daily routine. In the same time, he needs to be taught by the nurse about his disease and process of illness, so as much information (knowledge) he has, more easily the process of acceptance occurs. This explanation does not need to be said only one time, but in the different consults, which are reserved for him. Consequently, in the process to teach and manage his adaptation, working restriction must be considered because he is a farm, so a rouge part of his job needs to be revised provided that small portion of exertion. Thus, a holistic view for the mental process needs to be evaluated because in the process of adaptation a decrease in the level of self-esteem occurs although it can develop mental disorder such as depression. Mr. D. has an increase factor in this part sin ce he is a farmer, so restriction in the working routine facilitates this occurrence. Controlling it, community support (friends) is one method helping in his farm, so he has his job done with some help and regulating anxiety and other mental circumstance. Therefore, intervention is a primordial aspect in the process to care the patient, so it needs to have a holistic view to promote better quality of life not only for the client as well for his family. The last process in the Levineââ¬â¢s nursing process is the evaluation. The evaluation refers to the observation of organism (client) response to interventions. In the decision making assess the hypothesis to verify if it has done a support for the hypothesis or not. If the plan has not supported by the hypothesis, it is revised and proposed a new hypothesis to be applied (Alligood, 2010). Mr.D. and his nurse will evaluate his intervention knowing the quality of it, so modification and revisions may be necessary to do to provide better care in his process of life. Otherwise, all the process to adapt and provide health care is lost. Hence, evaluation is extremely necessary, and nurses must do it in every single client, as much it can be necessary. Finally, an action plan with a model of care is applied for Mr.D. The model of care more appropriate is the Expanded Chronic Care Model (ECCM), which has expand the focus of chronic care management toward health outcomes for client and community. This model expands the client to community a large view in the process of care, and support in all directions is provided to guaranty adequate quality of life (Kramer-Kile et al, 2014). The plan of care for Mr. D. some aspects to provide care and adjustment in his life are emphasize. Fist, teaching he and his family (first caregiver) about how to care and change the dressing in the surgical incision, and provide a nurse (in his community) to check weekly in his house if the surgical incision has been cared correct so as his process of adaptation is been accepted. Second, teaching about the illness and illness course, and it provides a focus in some chronic concepts such as sexuality, adaptation, isolation, stigma, and cultural. Also, provide support to understand and accept these concepts are essential. Then, involvement in community is necessary, so it avoids social isolation and increase self-esteem. Friendââ¬â¢s support is necessary, and they may help in the farm working, so Mr. D. could reduce psychological pressure because of the job. Fourth, psychological evaluation can determine if it is necessary to use antidepressant drug because a rouge change in his life has occurred. If necessary this type of drug, he needs orientation how to use and side effects that it can cause. Still, teaching about cardiac medication is significant, so it reinforces the management the correct time to take and side effects, which may be possible to occur. Fifth, cultural aspect about incapable may develop because he began to be restricted in his job. A support comprehension, which describes that he is capable to continue his activities, is decisive, so he is capable to do activities although some restrictions such as avoid high level of effort are necessary restriction. Sixth, body image is anothe r factor present because scar of the surgery will be present for the rest of his life, so understanding how to accept this aspect in his body is crucial for the quality of life. Last, family support in the process to accept the disease and provide adequate adaptation is required. Nurse may provide sources for his family to understand and know how to manage this illness in order that Mr. D. has more acceptance and provides involvement in his family in the process to care him. Indeed, the nurse and client develop action plan, so both must have agreements, which provides better care and process of adaptation. A revaluation these plans are indispensable, so adding or taking off part this may result. In brief, in the following paper was described Mr. Dââ¬â¢s story, some chronic concepts, which are related with his history, a succinct nursing theory description, which was Levineââ¬â¢s theory, the application the Levineââ¬â¢s conservation model theory for Mr. D., and action plans with a chronic care model may be applied for Mr. D. I have written this paper based in Mr. D., who is my father, and I thank him to have been given all this experiences for me in the process to care and manage his chronic illness. It is not easily to accept a new situation in the life and beginning to have adaptations in the inspected period of the life, so every chronic disease and illness are difficult to manage if the family and client do not have correct support to confront it. As a result, nurses need to have as much as knowledge possible doing research and applying nursing theories to provide better care and support for their clients and clientââ¬â¢s family.

Governments Must Balance Law with Individual Rights Essay -- Governmen
The topic of Government, laws and individual rights has always been on the minds of many people. Today is no exception, with the economy in poor shape and with a President who promises many changes to come. Will the changes really come? And if they do will they benefit the people of the United States of America or will they cause more violence and destruction to our economy? They say we have the right of free speech, to speak our minds and vocalize our opinions on topics that are important to us. They say we have freedom to choose our own religion and beliefs, to choose who we praise and what we believe to be right and wrong. They also say that we have the freedom to bear arms; to protect ourselves, and our country. Are these just words or are they really our rights? The constitution ...

Image Analysis Program :: essays research papers
Purpose: to become familiar with the image analysis program and to develop an understanding to the size and age of planetary nebulae Procedure The first part of the experiment involved using a picture of a church and back round to understand different pixels, ADU, zoom, and how to get the (x,y) coordinates. We then took this brief understanding of pictures and applied it to the stars. We loaded a picture of nebulae m42. After this we needed to calculate the average number of stars or solar masses. We found the (x,y) coordinates of a position in the center of the nebulae and on the edge of the nebulae. We used the following distance formula to find the distance between the points. After this calculation the answer in pixels needed to be converted to arc seconds for use in the small angle formula where 1 pixel approx. = 3 arc seconds. We now could use the small angle formula to find the actual radius in pc. Where d is the radius D is the distance from the Earth in pc and theta is the value we had just found out in arc seconds. After the calculation we needed to convert pc to meters so we used the calculation factor of 1pc=3*10^16m Now we needed to find the density. Density was figured out by multiplying the majority substance in the nebulae (hydrogen) per cubic m^3 by the mass of hydrogen in kg, which gave us the formula We then had the info we needed to find the mass of the nebulae. We calculated this by using a spherical shape for ease of calculation. We used the following formula where m is the mass p is the density and r is the radius found above from the small angle formula (d). Now that we had the amount of mass we needed to find the solar masses so we divided the mass of the nebulae by one solar mass unity in the following equation. Our next part of this lab was to find the age of the nebulae m57 . We used the same formula and procedure as before to find the radius of the star. The distance from Earth was given to us to complete the small angel formula. We then needed to convert from the au to km by the following equation. We were told the expansion of the nebulae to be 20 km/s and assumed this had been going on since the birth of the nebulae for simplicity of calculation.
The structure of memory Essay -- Technology, Multi-store Model
Introduction Prior research into the structure of memory have suggested that memory is comprised up from three separate stores each performing a specific and relatively inflexible function (in Passer, Smith, Holt, Bremner, Sutherland, & Vliek, 2009). That is the multi-store model, developed by Atkinson & Shiffrin (1968 in Passer et al., 2009) who claim a sensory memory store, short-term memory store (STM) and a long-term memory store (LTM) (in Passer et al., 2009). Although to some, the multi store model provided an adequate explanation of memory processes, it was regarded as being too simplistic since short-term and long- term memories were far more complicated than originally thought (in Craik & Lockhart, 1972). In essence, the multi-store model stresses the importance of rehearsal to long term memory. While rehearsal is crucial as a means of transferring information from the STM to the LTM, this is not necessarily always the case (in Atkinson & Shiffrin, 1968 in Passer et al., 2009). To this , sceptics challenged the idea of information being transferred from the STM to the LTM by active rehearsal since subsequent research has indicated that information had the potential to be stored in the LTM without it being actively rehearsed (in Atkinson & Shiffrin, 1968). In response to the difficulties and weaknesses presented in the multi-store model, an alternative model attempting to explain memory processes in a more precise manner was developed by Craik & Lockhart (1972 in Craik & Lockhart, 1972). Their theory of levels of processing proposes that different methods of encoding information into the memory will subsequently have an effect on recollection of information (in Craik & Lockhart, 1972). According to the levels of process... ...rformance. For example, Craik & Lockhart (1972) found that individuals who processed information at a semantic level produced better recalls followed by acoustic processing and then visual processing being the least effective in terms of remembering. The results fundamentally imply that engaging in semantic processing tends to yield higher levels of memory performance compared to acoustic and visual processing thus reflecting the findings of Craik & Lockhartââ¬â¢s (1972) and that memory was enhanced more by depth of processing rather than how long information was rehearsed for as previously pointed out by the multi-store model. It also showed a greater amount of recall for deeply processed words than for shallowly processed words. In addition, the study also revealed that the effect appeared to be stronger for the ââ¬ËTrueââ¬â¢ responses that for the ââ¬ËFalseââ¬â¢ responses.
