Nursing Theory

Question 1 A). Describe in your own words what you believe nursing is? -Nursing is responsible to look after sick and injured people . It is a duty of care to assess, planned ,help what their needs to keep them healthy ,comfortable and happy. A nurse must have ability to ensure their knowledge , skills ,and experience and confident to ensure their profession. B). Provide an overview of each Nursing Theory. -Self-Care Deficit Nursing Theory (Orem) Dorothy Orem’s self care deficit theory, general theory of nursing is one of the host widely used model in nursing today. In 1914,Orem was born in Baltimore ,Maryland. She received her nursing diploma in the early 1930’s from Providence Hospital School of Nursing ,Washington D. C. In addition to earning a BSN Ed. (1939) and MSN Ed. (1945), She has received three honorary doctorates and an Alumni Achievement Award For Nursing Theory in 1980 from Catholic University of America. (Hartweg,1995). In 1978, Orem (citied in Faucett, 2005) connected that the task required in dentification of the domain and boundaries of nursing as a science and an art . After reflecting upon her own nursing experience, Orem says then answer . come to her as a flash of in sight an understanding that the reason why individuals could benefit from anything was the existence of self care limitations. -Interpersonal relations Model (Peplau) In 1952 Hildegard Peplau made an attempt to analyse nursing action using an interpersonal Page1 Theoretical framework. Her theory focuses on the relationship formed by people as they progress through each development stage. She viewed the goal of nursing as developing a relationship between the nurse and client whereby the nurse acts as resource person, counselor, teacher and surrogate. -Complementary-Supplementary model (Henderson) In 1964 Virginia Henderson described the goal of nursing as helping the client to gain independence as rapidly as possible and defined nursing as assisting the individual sick or well ,in the performance of those activities contributing to health, is recovery promoting quality of life or to a peaceful death that the client would perform unaided if he or she had the necessary strength, will or knowledge. Henderson identified 14 basic needs that provide a framework for nursing care. These are breathe normally, eat and drink adequately, eliminate by all avenues of elimination, move and maintain a desirable position, sleep and rest, select suitable clothing, dress, and undress, maintain body temperature within normal range, keep the clean and well groomed, avoid dangers in the environment, communicate with others, workship according to faith, work at something that provides a sense of accomplishment, play or participate in various forms of recreation, learn, discover or satisfy the curiosity that leads to normal development and health. hrough each development stage. She viewed the goal of nursing as developing a relationship between Nursing theory The patient in this case has a condition that puts him at risk for illness and injury. uk/nursing-scientific-management-and-frederick-taylor/">A nursing theory is a conceptualization of some aspects of nursing communicated for the purpose of describing, explaining, predicting and or prescribing nursing care (Jacqueline, 2001). Imogene king’s theory focuses more specifically on the events and the phenomena of the discipline and is specific enough to contribute on a sound basis for achieving an effective behavioral outcome in this case study. Applications of these theories in practice depend on the awareness, understanding and research on their interrelationships (Patricia A Potter, 2005). The American Nurses Association (ANA) is a full-service professional organization representing the nation's entire registered nurse population. The ANA represents the interests of the nation's 2.7 million registered nurses through its 54 constituent state and territorial associations and over 150,000 members. It is dedicated to ensuring that an adequate supply of highly skilled and well-educated nurses is available in USA. ANA is also committed to meeting the needs of nurses as well as health care consumers (http://www.nursingworld.org). Imogene King (Jacqueline, 2001) formulated a goal attainment theory which focuses on three dynamic interacting systems namely, personal, interpersonal and social systems.   According to this theory, a personal relationship occurs between the client and the nurse, and this nurse-client relationship is the vehicle for the delivery of nursing care, which is defined as a dynamic interpersonal process (Jacqueline, 2001).   This theory emphasizes on the fact that the nurse and the client are affected by each other’s behavior and it is duty of the nurse to maintain this interpersonal process. King's Goal Attainment Theory involves a process where the nurse and the patient mutually communicate information, establish goals, and take action to obtain the common goals. This theory is about the interpersonal process where two people, usually strangers come together in a health care organization to obtain their health goals. This goal attainment theory is based on personal and interpersonal systems, which includes interaction, communication, transaction, role, stress, growth and development, time and space. Goal attainment in this model is achieved through a goal-oriented nursing record, which is composed of five major elements namely, a database, a problem list, a goal list, a plan and progress notes. Active participation of the client in the process of goal setting and goal achievement are the major strengths of this model. This model framework is useful for nurses in social interactions with clients. This theory is based on the principle that each individual (client) brings to an interaction a different set of values, ideas, attitudes, perceptions to exchange  and the other person (nurse) receives this information and processes it. Thus, these two individuals mutually identify goals and the means to achieve them. In this interaction process they reach an agreement about how to attain these goals and then set about to realize them (Jacqueline, 2001). According to King’s theory, Patient participation with the elements of communication, expression, interaction with the nurse is the most important factor, which keeps alive the interpersonal process of personal relationship. This brings the nurse and the patient to a common goal and both of them strive to achieve this common goal. This is supported by the strategies, the nurse record of the outcomes and the statistical analysis of the data. CONCLUSION Thus today Nursing is a profession rather than a vocation. Nursing as a profession accounts for its conscientious, knowledgeable and responsible actions.   The profession has extended education avenues, a body of knowledge leading to defined skills, an ability to provide specific service, professional autonomy to make decisions governed by a code of ethics (Patricia A Potter, 2005). The theoretical models have served as frameworks for nursing curriculum and practice by increasing the scientific basis of nursing practice and in USA, ANA has been continuing its efforts to expand the scientific and research base for nursing practice, for the collective bargaining rights and workplace advocacy for all nurses, to gain better compensation and better working conditions for nurses, and to implement new ways in which nursing services can be delivered to respond to current and future demands for cost-effective, quality health care ( http://www.nursingworld.org ).It Strives to shape the future of healthcare through excellence in nursing education using education, science and technology to improve health.

Final Question 3 - Essay Example The main basis of setting the limits of the hazard chemicals and the corresponding related OSHA standards entail initiation of the extent of potential exposure and the lofty extent of dermal hazard. Potential exposure is set by approximating the risk of the chemical splash, important differences within the work practices amidst individuals, use of gloves against hand tools when an individual comes into contact with direct contact with the underlying chemical and utilization of the shared tools (Noll et al, 2014). Conversely, dermal exposure potential is mainly based on the frequency and period of the skin contact, size of the skin in contact with the prevailing chemical, concentration of the chemical and likelihood of retaining the chemical on the skin. TLV is applied in in the prediction of the quantity of chemicals all healthy personalities or worker can withstand without severe effects. STEL is utilized by employer is ensuring that no worker is exposed to an airborne concentration of the formaldehyde that exceeds two sections of the formaldehyde foe every million sections of air. NIOSH IDLH is the main source of the general industrial hygiene information for the employees, managers and corresponding occupational health professional in regard to the hazardous chemicals. These values are normally utilized by the EPA in the establishment of plans and response to the underlying uncontrolled releases of the hazardous chemicals (Noll et al, 2014). Moreover, aid in approximations of the exposure, offering of the vital information for assessing chemical release and taking appropriate protective

Adult Learning in Context - - Case Study Example I have an experience of working with adult learners when a CEO of a printing unit near my home requested my services for improving the communication abilities of their production workers. This unit was consisting of around 100 printing workers from different countries. Because of the diversity in workforce, this unit faced so many troubles in effective communication which affected their growth prospects immensely. Even though the workers were skilled ones, lack of understanding between them resulted in lack of coordination and subsequent production problems. The company CEO asked me to give the entire production staff week long training with respect to effective communication in a multicultural environment. The training session was arranged after the regular schedule of the works and lasted for two hours continuously for a week. This paper is written as a case study based on the experiences I received from adult learners of the week long training class I have taken for around 100 pro duction workers from different countries. CAEL, (n. d) has mentioned that adult students have unique needs like Academic and motivational advising supportive of their life and career goals and Recognition of previously obtained experience- and work-based learning (CAEL, n. d., p. iv). Most of the workers who attended the training were keen in seeking advices from me for their career goals. Unlike the normal students, adults showed no hesitancy in clearing their doubts. But most of their doubts were related to their career goals. They were eager to know about the possibilities of building a successful career with the help of improved communication abilities. Another important factor which attracted me was their enthusiasm in incorporating their past work based knowledge to the topics which I explained in the class. For example, when I explained that information communicated through nonverbal means are more than verbal means, most of them agreed with it. Some of them

Theodore McKenzie Essay Example | Topics and Well Written Essays - 1250 words

Theodore McKenzie - Essay Example His shirt, damp from the humidity, outlining his lean built and his broad shoulders, bonded tightly onto his skin. Like tiny crown jewels, droplets of sweat constellated on top of his straight yellow hair - comparable to the colour of the corn kernels. In fact, Theodore remembered other boys referred to him as a corn child, not to mock him or anything - except that he stood out among the rest of the children whose skins were less pallid and whose hair was as dark as burnt wood. Theodore, when he was a child, on his way home from school, used to pass along the tiny path in the middle of the cornfields. Cornfield farmers usually allotted space in between rows of corn so that it would be easy for them to cut grass and weeds that 'affect growth of maize' at least that was how Simeon, an ageing lanky tenant who lives in a shack near the foot of the mountains, explained it. Simeon's wife used to beat him up with corn stem every time he comes home drunk after swigging a jar of coconut wine concocted by the residents in the valley. Theodore remembered the paths to be always free of weeds and he thanked Simeon and the farm workers for that. The brownish soil formed mounds and crests just like those of waves, and when it rained - as it always rained - water cruised along the paths, and the soil glued firmly on his shoes, like sticky rice cake fixed on one's tooth - elevating his black leather boots a few centimeters more. Theodore could not bear walking like that an d he would often take his boots off and walk barefoot towards home. Although sometimes, the blades of corn leaves protruding towards the path and towards him, would cut gently through his skin as a knife with a jagged edge would cut a pinnate leaf, leaving linear marks on his arms. When he was a boy, Theodore recalled going home one day after school, passing through the fields, towards the end of the vast plantation where a lone Baroque-inspired mansion formidably stood. His house was the only structure that could be seen from afar - even if it was viewed from the hills or from the mountains or tens of kilometers away. Its red brick roof looked like a red piece of cloth on a yellow floor during that time of the year, as the plants were almost ready for harvest. The corn's golden kernels still sparkled under the setting sun casting a red glittery reflection on each bead. Almost everyday on his way home, as he approached his house, Theodore would always hear his mother playing music, humming a tune or fingering Wagner on the piano. He didn't know Wagner nor liked his music but his mother manipulated her favorite musical instrument with passion, a kind of ardor, which Theodore had never seen in someone else's fingers or behavior. Today was a strange day though. On his way towards the door, Theodore didn't hear the piano nor hear his mother humming a tune. Instead he heard his father's voice. It was shaky but apparently angry. "What do you mean you don't know where she went" his father was interrogating Teresa, one of the housekeepers. " She is gone Senor Leopold. I looked everywhere. She was not in her room either." "Are you sure you looked in the neighborhood for her" From the doorway, Theodore saw his father's anxious face, his brows creased and his lips parted and shaking like a leaf hanging onto a stem. "We have looked everywhere and we saw one of the suitcases" His father swiftly interrupted the young maid. " She wouldn't do that!

Social media - Essay Example However, fashion brands also have to be aware of the difficulties that they raise by adopting the digital approach. In recent years, social networking websites such as Facebook and Twitter have developed a platform for people to connect and create a community for mutual interests. Social media not only allows consumers to interact and build relationships, it also helps to stimulate discussions on key ideas, thoughts and interests. Since social media has become widely used for communication and businesses have kept up with fast pace of the change in technology and incorporated this emerging, innovative platform into their marketing strategies. Social media marketing has become a significant element for digital marketing as it allows businesses to learn about customers and provide support in order to improve the consumer perception towards the company. (Chaffey & Ellis-Chadwick, 2012) (P.535) Even though social media is identified as a low-cost media platform that allows businesses to communicate brand activities, the adoption of social media by fashion houses was a little slower as they fear that their well-developed brand images would be damaged by the transparency and openness of the brand information. While traditional advertising channels have more control on the output and minimize the risk of their messages being misinterpreted, such an approach invariably has its costs. (Meadows, 2012)(P.163) The brand was founded in Toronto, Canada in 1985 and acquired as a subsidiary of Polo Ralph Lauren Corporation in 1999. As such, it is a popular fashion and lifestyle brand among international shoppers and is distributed in more than 115 stockists ; spanning from the United States, Canada, Hong Kong, China, Seoul, Singapore and a litany of others. By using the brand’s highly acclaimed blog, Culture Club is the highlight of its social media marketing strategy and develops alongside other social media platforms to distribute the

The Real Cause of Conflict Essay Example | Topics and Well Written Essays - 1000 words

The Real Cause of Conflict - Essay Example Over the years several psychologists have developed tests to evidence and describe the different personality types, including Jung, Myers-Briggs and the Big Five Personality Tests, which is now the most extensively acknowledged and used model of personality. The Big Five was developed in the 1970's by two different research studies which though completed differently came to similar conclusions: that a majority of personality traits can be defined under five broad themes, extroversion, emotional stability, orderliness, accommodation and intellect. All other personality traits can be correlated to one of these independent personality traits (Howard & Howard, 2007). However, there is a weakness with this theory, as researchers have not been able to completely agree on what exactly the fundamental aspect of each personality trait is (Howard & Howard, 2007). People frequently seek and admire personalities that are different from their own, and being appreciative to these positive attributes they have may hinder them to realise it could cause stress and be a significant contributor to disagreements. Usually people seek out individuals who fill these personality differences, in which to have personal or working relationships with. A lot of people who have personalities where they are exceptionally well-organized are often drawn to partners who have a preference to handling situations in an easy going and effortless manner. In comparison rational, sensible thinkers prefer affectionate, sensitive partners, and vibrant extroverts may have a preference for strong, quiet people (Landau & Landau, 1997). The same can be apparent in working relationships between co-workers. This is most likely because they perceive their counterparts as being more relaxed at managing situations they themselves would find hard to achieve (Landau & Landau, 1997). As Smallwood (2009) states, differences in individual personalities can work to an advantage in teamwork, as there is an chance for the team members to merge together, not in the case that everyone thinks the same and agrees, but that everyone's individual strengths and abilities can work together to create a stronger, and more effective conclusion or solution to the problem they are working on. HowveHHowever, these personality differences can also cause significant problems when working in a team, as they clash rather than compliment each other (Smallwood, 2009). These problems may occur when one individual feels that their way is the only 'right' way to do something. However, as evidence shows there is always more than one way to reach the same result, and an individual can learn a lot from watching how another person achieves these results. Smallwood (2009) suggests that teams do require different personalities to produce an effective work environment where the different attitudes and abilities produce an effective whole, from its different parts; however, it is easy for an individual to become judgemental of another team member who does a task in a different way from which they would, rather than appreciating the differences. In addition, team members will sometimes judge the behaviour of a co-worker, by assuming they are feeling a certain way because of their outward behaviour. For example, if a co-worker is quiet, the individual may assume that they are angry, as this is how they

Eyvonne's Theory's Essay Example | Topics and Well Written Essays - 750 words

Eyvonne's Theory's - Essay Example This theory attempts to explain different masculinities by questioning what was taken for granted in existing understandings of nature and society, they revealed such knowledge as male knowledge which gave a spurious legitimacy to women's inferiority. This theory could help to change the role of men as national leaders and sport stars. By redefining the most intimate of human relations as political, rather than as private, radical feminists politicized sexuality and exposed men's normal, everyday behavior as a widespread social problem. The approach is to revise the status of women in the society and gives them more freedom and independence in political and social spheres (Reinharz and Davidman 23). Social constructivism allows a researcher to explain and examine how social processes develop in social environments. Applied to masculinity, this theory helps to examine gender differences as social constructed phenomena and social interaction. This theory attempts to explain different masculinities to explain how people make sense of experience in everyday interaction or in problem-solving activities. Social constructivism ought to be useful in predicting how any given set of circumstances might be changed to improve the opportunities of persons who wish to learn in such situations. Masculinities can be thought of as a social process of making sense of experience in terms of what is known. To improve social relations, therefore, a n individual might consider how to improve the quality of each of the four components (i.e., social process, making sense, experience, extant knowledge). Social constructivism might offer a solution to such problems as socialized gender roles and health related problems. This theory can help men to think in terms of improving the quality of their health, providing a range of meaningful experiences to each learner, and making it possible for each one to become aware of their relevant prior knowledge and apply it to the process of healthy life style. The solution is to change traditional gender roles based on real life experience and knowledge (Reinharz and Davidman 38). Part 2 "Fear of Falling" vividly portrays social and personal problem s faced by middle class women in modern society. Liberal feminism could help to analyze and examine problems and roots of social identity and professional development. Many women have followed a long tradition of campaigning for improved rights and opportunities for women without seriously questioning the existing organization of society (Orenstein 53). Gender socialization of adolescents is influenced by modern social relations which are concerned primarily with concepts of justice and equality. Women suffer injustices because of their sex and are organized around campaigns for equality and redistribution: equal pay, equal civil rights, equal access to education, health and welfare, equal access to the democratic political process (Reinharz and Davidman 102). A research plan would aim to test the main concepts and notions which influence professional life of women and their social relations. The hypothesis would be based on the idea that women are widely discriminated against because of their gender, but does not identify the relations between the sexes as specific power relations. The hy

Synthesis of CNTs From Hydrocarbons Resources by CCVD

Synthesis of CNTs From Hydrocarbons Resources by CCVD 1. Introduction Carbon nanotube is one of the most promising candidates of nanomaterials which own wonderful mechanical, electrical, and thermal properties. With one hundred times the steel’s tensile strength, thermal conductivity better than all materials except the purest diamond, and electrical conductivity contact to the copper with ballistic transport of electrons present the ability to carry much higher currents without heat generation. Carbon nanotube can be categorize to single-walled carbon nanotube and multi- walled carbon nanotubes, when SWCNT has one rolled layer of graphene sheet to form cylindrical shape, MWCNT consist of multiple cylindrical rolled graphene sheets (Fig. 1). General carbon nanotube synthesis methods are Arc discharge, laser ablation, and chemical vapor deposition (CVD). However, CVD is the most convenient method to grow all kinds of CNTs and the best choice to produce large amount of CNTs at relatively low cost and with mild growth conditions. The use of hydroca rbon resources for the production of high-value chemical and materials such as carbon nanotubes obtain obvious impact of sustainable development. In this direction, several research groups have explored the use of hydrocarbons as a carbon sources for CNTs synthesis. 2. Synthesis of CNTs by Catalytic Chemical Vapor Deposition Recently, Catalytic chemical vapor deposition (CCVD) is the most familiar technique to grow all kind of CNTs. Several motives can explain this favoring. Firstly, consider the technical operation it is easy to perform the reaction between a catalyst and a carbon precursor; it only requires an oven designed with a tubular reactor such as quartz tube, and a few of gas flow controllers in order to feed the require gases. Secondly, a numerous of parameters can be contrasted and investigated from the scientists, not only during the catalyst treatment but also the CNTs growth, which influence the quality, purity, and yield of the CNTs. The mainly vital parameters for CNTs synthesis by CCVD technique is the temperature. In CCVD, energy is donated to hydrocarbons to break them into reactive radical objects in the temperature range approximately from 500-900Â °C, sometimes more. These reactive species diffuse down to a catalyst surface where they remain bonded. As a result, CNTs are formed. T he commonly used energy source is resistive heating. Generally, there are two processing system patterns for CCVD to synthesis CNTs are horizontal and vertical system. In this literature we will demonstrate a usual horizontal system due to it is far reaching for most scientists. I horizontal system there are two techniques for utilization floating and fixed-bed catalyst technique, displays in Fig. 2. Floating catalyst mainly apply when a mixture of reactants and catalyst are present in the gas phase in the reactor at a promoted temperature during CCVD process. The catalyst in the gas phase experience transformation cause by the redox gases and or the elevated temperature and form solid phase nano particles where the CCVD reaction occurs. This method enclose on obstacle in preventing the nano particles and reactants from coalescence which is when the solid catalyst nanoparticles hold on the reactor surfaces, they could have adequate residence time for CNTs growing. In other words, any unreacted gas precursor and solid catalyst nanoparti cles which they have not capable to react and holds on the reactor surfaces at adequately elevated temperatures are swept away from reactor with the carrier gases and unused reactants. Therefore, the result practically will reduce the productivity and process efficiency. In the fixed bed process, the catalyst which is in the solid phase is set in boats and places inside the reactor then the reactant with carrier which they are in the gas phase are introduced at an elevated temperature where the reaction takes place in CCVD. The efficiency and productivity of CNTs growth in this system are limited by heterogeneous contact between the gas and solid reactant and ascent of the reactor gradients temperature. Because of increase growing nanotubes it cover the catalyst nanoparticles surfaces, the diffusion of carbon precursor to the catalyst nanoparticles will decrease. Therefore, the effectiveness of the catalyst nanoparticles surfaces will reduce. 2.1. Catalyst Catalysts play an essential role for synthesis of CNTs in the CCVD and hence enhance the suitable characteristics of desired catalyst will be improved the attained CNTs quality and process yield as well. Transition metals in the figure of nanoparticles such as Iron (Fe), Cobalt (Co), Nickel (Ni) and their alloys have been specified as the most effective catalysts for CNTs synthesis. These catalysts can Growth CNTs in three steps according to Vapor-Liquid-Solid (VLS) mechanism: Firstly, a gas precursor produces carbons which adsorb and dissociate on the surface of the catalyst particles to form elementary carbon atoms. Secondly, the carbon atoms dissolve in the bulk of the nanoparticles to form liquid metastable carbide and diffuse within the particles. Finally, solid carbons precipitate at the rear side of the nanoparticles to form carbon nanotubes. Solid organometallocenes such as nickelocene, cobaltocene, and ferrocene are extensively used as a catalyst for utilizing CNTs, because they deliver solid metal nanoparticles which effectively catalyze the hydrocarbons decomposition. Experimentally, the catalyst particle size is in charge of CNTs diameter. Figure 3 (c) summarize that catalyst particle diameter plays a significant role for determining the structure the utilized nano carbon. Catalyst nano particles with 1 nm diameter mainly utilized SWCNTs [ ], while MWCNTs are utilized from catalyst nanoparticles with diameter 0f 10 – 50 nm as well as the number of MWCNTs layers increased with the particles diameter. In other hand, another nano carbon structure named nano-onion utilized when catalyst nanoparticles with diameter exceed 50 nm. Attaining hydrocarbons decomposition on the catalyst surface unaccompanied and preventing the aerial decomposition is the Key of obtain pure CNTs. Furthermore, alloys have been proven to gain higher catalytic activity comparing with pure metals. Despite considering the Fe, Co, and Ni metals nanoparticles the effective catalyst for CNTs synthesis, other metals such as Cu, Au, Ag, Pd, and pt as well were discovered to be catalysts for CNTs growth from a variety of hydrocarbons. Therefore, this is unlocked field of research to utilize different CNTs technique with variety hydrocarbons by adjusting temperature and pressure. 2.2. Hydrocarbons decomposition and Thermodynamics In order to understand the reaction in the CCVD, the main aspect which should be taken in our consideration is thermodynamics. The reaction fulfill to the creation of solid carbon nanotubes have be thermodynamically usefulness under the selected temperature and pressure conditions. Gibbs free energy (ΔG) is the key for extraction this information. In the term of the pyrolysis of hydrocarbons ΔG depends on the reactivity of the hydrocarbon for example; whereas methane’s decomposition is thermodynamically preferable above 600 Â °C because it is the most stable hydrocarbon molecule, ΔG for ethylene, acetylene or benzene is already negative at 200 Â °C figure 3a). The expert found that CNTs are frequently synthesized by CCVD using methane precursor at temperature of above 850 Â °C due to the slow reaction rate, while CVD synthesis of CNTs using acetylene is often carried out at temperature of 500-750 Â °C and for ethylene is 650-850 Â °C. [ , , , ] High quality of SWCNTs is usually utilized by CO decomposition over metal nanoparticles, but this reaction is thermodynamically limited above 600 Â °C. Therefore, the reaction required high pressure about (10-30 bar) to substitute the equilibrium for growing feasible yields of SWCNTs. [ , , ] Magrez et al. established possibility of growing high quality of MWCNTs when added stoichiometric amounts of CO2 and C2H2 by CCVD at 400 Â °C[ ]. The solid carbon formation happens by oxidative dehydrogenation of acetylene as a substitute of dehydrogenation or pyrolysis. Thermodynamically, the reaction of CO2 addition is favorable. While numerous reaction paths are feasible, the solid carbon formation accompanying with CO and H2 is favored. It is quite clear now also possible to accomplish the attained knowledge to discover reaction conditions which gives the greatest solid carbon formation to obtain highest CNTs yield. Figure 3. Thermodynamic data calculated with the ChemKin database. a) Gibbs free energies of formation for various carbon precursors. The energies are normalized to the number of carbon atoms in the precursor and correspond to its pyrolysis. b) Gibbs free energies of typical reactions: CO disproportionation, water gas shift, oxidative dehydrogenation of acetylene, and pyrolysis of ethanol. The energies are normalized to the number of solid carbon atoms. 2.3. Carbon Precursor for Catalytic Chemical Vapor Deposition The carbon precursor plays an important role in the growth, characteristics and properties of CNTs, because of their own binding energy, type and role of reactive groups and thermodynamic properties. Concerning gaseous carbon precursors, the CNTs growth efficiency depends strongly on the concentration and reactivity of gas phase intermediates produced simultaneously with reactive radical species as a result of hydrocarbon pyrolysis. Therefore, it is expected that the most capable intermediates, which have the ability of physisorption or chemisorption on the catalyst surface to initiate CNTs growth, suppose to be produced in the gas phase. A comparison of produced CNT characterizations showed that there is a relationship between chemical structures of hydrocarbons and the CNTs formation [5,7,17,49,62,64,74–77]. Hernadi et al. [49] affirmed that unsaturated hydrocarbons have much higher yield and deposition rate than saturated gases. Besides, saturated hydrocarbon gases manage t o produce highly graphitized filaments with fewer walls compared to unsaturated gases. Consequently, they suggested that saturated hydrocarbons are favored for SWCNTs growth and unsaturated hydrocarbons for MWCNTs. However, SWCNTs have been obtained from a highly diluted unsaturated hydrocarbon [10,19,23,38,40,47,75,76,78,79]. The growth of clean SWCNTs was observed at relatively low temperatures using alcohols with various catalysts [19,25,30,64,81–85]. The authors concluded that alcohols are much better carbon sources for SWNTs than hydrocarbons and this is likely due to the ability attributed to OH radicals to etch away amorphous carbon deposits. General experiences show that low temperature CVD about 600–900Â °C grow MWCNTs, while high temperature at 900–1200Â °C reaction favors utilizing SWCNTs. The results indicate that SWCNTs have a higher energy of formation due to small diameter and high curvature which tolerate the high strain energy. Therefore, SWCNTs grow from only selected hydrocarbons such as carbon monoxide, and methane which have an equitable stability at higher temperature, whereas common effective precursor for MWCNTs such as acetylene, benzene, and xylene are unstable at higher temperature which lead to deposit a large quantity of amorphous carbon. Hata et al. synthesized a highly efficient of impurity-free SWCNTs by water assisted ethylene on substrate in CVD method (Hata et al., 2004). It was reported that controllable rate of steam into the CVD reactor operated as mild oxidizer leads to selective remove of amorphous carbon without harmful the CNTs growth. Controlling relative rate of ethylene and water steam was essential to minimize catalyst’s poison. These studies ascertain prove that carbon precursors play an important part in CNTs growth. Thus, by accurate selection of carbon precursor and water vapor rate, not only the catalyst’s lifetime but also CNTs growth could be crucially maximized and therefore both quality and yield of CNTs could be improved. Hydrocarbons such as carbon monoxide, methane, ethylene, acetylene, benzene, and xylene are typically the most commonly used CNT precursors. Among the essentially experiences of synthesis CNTs by CVD technique are that MWCNTs ware grown from the decomposition of benzene at 1100Â °C [] and acetylene at 700Â °C []. Both of these reports were used iron nanoparticles as the catalyst. As well as, MWCNTs were also grown from many other hydrocarbon precursors including cyclohexane [] and fullerene []. As well as, MWNTs were utilized from supercritical toluene at 600 Â °C and using ferrocene as growth catalysts, the toluene serves not only as the carbon source for nanotube formation but also as the solvent. On the other hand, synthesis of high purity SWCNTs at low temperature was reported when Fe-Co supported on zeolite utilized as a catalyst in alcoholic CVD and since then, ethanol consider as the most common universal CNTs precursor in the CVD method. Particular aspect of ethanol for growing CNTs with nearly free from amorphous carbon due to the effect of OH radical which operate as the mild oxidizer. Afterward, vertically aligned SWCNTs were grown as well on Mo-Co supported on coated silicon substrate. Lately, the articles have been shown discontinuous supply rates of acetylene to ethanol CVD apparently assists ethanol to increase the catalytic activity and therefore enhances the CNTs growth rate. Apart from the well-defined chemical reagents described above, CNTs have also been successfully and systematically synthesized from domestic fuels such as kerosene (Pradhan et al., 2002), liquefied petroleum gas (Qian et al., 2002) and coal gas (Qiu et al., 2006).

Important Of Sight For The Purpose Of Survival Biology Essay

Important Of Sight For The Purpose Of Survival Biology Essay The importance of sight has been one of the most taken for granted systems in the human body. Sight, like the other four senses, plays an important role in the survival of an individual. In primitive humans, a loss of vision would make predator avoidance and food gathering difficult. Hence, there is an evolutionary pressure to maintain vision even when the eye sustains injury. While the eye is highly developed, certain post trauma mechanisms have evolved in such a way that our visual axis will not be altered, which would normally lead to instant blindness. Damage done to any normal part of the body usually leads to some sort of immunological response, including inflammation caused by the lymphocytes. Due to the physiology of the ocular system of mammals, the cornea cannot sustain inflammation, which can lead to the changing of the visual axis, thus leading to blindness. In primitive man, blindness could potentially lead to the individuals death. In order to prevent this, certain immu nological responses are suppressed in the cornea, allowing vision to remain. Keratitis is the clinical diagnosis of inflammation of the cornea, which if left untreated, can lead to blindness of the patient. This paper will use the Darwinian Medical approach and the Adaptationist Program to discuss the implications of the suppressed immune response in development and treatment of keratitis and the various microbial and mechanical causes thereof. In order to understand topics covered in this paper, a basic explanation of structures of the eye, their functions, as well as mechanisms and associated pathogens must be explained. Keep in mind, what will be mentioned is a buildup all to save the visual axis. The main anatomical focuses of the eye for this paper are the cornea and the anterior chamber. Concluding this will be a brief description of Darwinian Medicine and the Adaptationist Program. The cornea has two main functions and is composed of five layers. It acts as a protective membrane for the eye. The five layers consist of the following, in order from anterior to posterior, an external stratified squamous epithelium, an anterior limiting membrane (Bowmans membrane, the basement membrane o the stratified epithelium), the stroma, a posterior limiting membrane (Descemets membrane, the basement membrane of the endothelium), and an inner simple squamous endothelium. 1. The main functions of the cornea are to act as a protective membrane as well as to be the transparent window that allows light to enter through the eye to the retina. This unique transparency is due to the uniformity of the cell structure, being devoid of blood vessels, and being in a constant state of dehydration. If the epithelium is damaged, there is only a temporary regional build up of watery fluids in the stroma. However, if trauma is severe enough to expose any corneal layer below the epithelium, the cornea then becomes susceptible to infection of a variety of pathogens. These include, but are not limited to the following: bacteria, fungus, amoeba, and herpes virus.2. Without medical intervention, the basic stages of corneal infections are as followed: trauma, entrance of pathogen, inflammation of the cornea, ulceration, loss of vision, and even possibly loss of the eye. Located between the endothelium of the cornea and the iris, is a fluid filled cavity called the anterior chamber. The anterior chamber of the eyeball is filled with thick liquid-like substance called the aqueous humor. Its primary function is to maintain a normal intraocular pressure as well as provide nutrition for the tissues with no veins attached to them. In the anterior chamber, specifically the aqueous humor, there is a presence of a wide variety of immunoglobulins, as well as a wide variety of immunosuppressive substances such as transforming-growth-factor- Ã‚ ¢ and macrophage-migration-inhibitory-factor. A theory deemed Anterior-chamber associated immune deviation will be discussed later in this paper alongside with ocular-immune privilege. 3. The Darwinian Medical approach looks at both proximate, biological causes, as well as the ultimate, evolutionary causes to explain a disease or an immune function such as a fever. Ultimate causes are usually more complex in their explanations, which include defense, infection, novel environment, genes, design compromise, and evolutionary legacy all of which are evolutionary driven by four forces: natural selection, mutation, gene flow, and genetic drift. Evolutionary causes of an excessive and uncontrolled defense mechanism can affect the risk of the disease. Other risk factors include losing the evolutionary arms race, the preservation of an allele that is harmful, and the result of evolutionary constraints. While keratitis is classified as an infliction, it is actually an immune response related to the infiltration of a pathogen in the cornea. As stated above, keratitis is the inflammation of the cornea. Symptoms include mild to sever pain in the eye, redness of the eye, opaque cornea, photosensitivity, and tearing. Clinical diagnosis of keratitis is done through examination using a slit lamp and proper illumination, Fluorescein stain to detect superficial corneal lesions, and laboratory examinations of corneal scrapings to detect pathogens. 2. Inflammation caused by pathogens is potentially harmful leading up to corneal ulceration, loss of the visual axis, and potentially blindness. The inflammation however is the lesser of two evils, for without having this immune response, the sight of the infected would be doomed to blindness. While this is true, an eyes last-ditch effort to remove the pathogen leads to over-inflammation and ulceration of the cornea. At that point, unless a corneal transplant is done alongside with medicine to kill the pathogen, the eye has given up and the host goes blind. To regulate inflammation and prevent ulceration, it has been hypothesized that there is design compromise called ocular immune privilege in the eye that regulates inflammation up to a certain point. This will be discussed later. The epidemiological qualities of keratitis fluctuate etiologically as well as geographically. Keratitis has risen in both developing countries as well as modernized countries, afflicting people worldwide with no restrictions based on economic status. Thousands of patients each year are diagnosed with some form of pathogenic keratitis, having each pathogen found in particular environments found worldwide. Anyone involved in agriculture is usually at risk for fungal keratitis. Anyone wearing contacts are at an even higher risk for not only fungal keratitis, but also bacterial and amoeba induced keratitis. However, anyone who has any sort of ocular trauma led to lesions in the cornea is susceptible to any form of microbial keratitis. 2. The evolutionary legacy of ocular immune privilege is the result of evolutionary constraints and design compromises. In order to preserve the function of the eye, inflammation is regulated by the hosts adaptive immunity, specifically called ocular immune privilege. Immune privilege has been recognized in only three organs; the testes and ovaries, the brain, and the eye. 5. Coincidentally, these are some of the most important organs in the body related to survival and spreading of ones genome. Adaptive immunity is compromised of lymphocytes that throughout life generate unique receptor molecules that recognize with extraordinary specificity molecules expressed by invading pathogens. 3. (pg 11). It is important to understand this concept to elucidate the mechanisms of ocular immune privilege and ACAID. Ocular Immune privilege was first described about 130 years ago. However, its importance was not recognized until the early 1940s by P.B. Medawar and his colleagues. During the 1970s, it was discovered that ocular immune privilege was caused by anatomical, physiological, and immunoregulatory processes, which prevent the introduction and expression of immune-mediated inflammation. Many ophthalmological researchers agree that ocular immune privilege is an adaptation for reducing immune-mediated injury to ocular cells that have limited or no capacity for regeneration.6. The three major mechanisms of ocular immune privilege are as followed: (1) there are anatomical, cellular, and molecular barriers in the eye; (2) eye-derived immunological tolerance (ACAID); and (3) immune suppressive microenvironment in the eye. 5. Anterior chamber-associated immune deviation, or ACAID, is directly related to the ocular immune privilege theory. ACAID is characterized by impaired antigen-specific delayed -type hypersensitivity and reduced production of complement fixing antibodies. 3. It is an observable fact that allows the antibody response but not the cellular responses mentioned above. 5. The discovery happened when there was a prolonged survival of genetically different transplanted tissue survived in the anterior chamber of the eye. The failure of the immune system to bring forth an immunological response composes the characteristics of immune privilege. This is the reason why corneal transplants are one of the most successful, and least rejected tissue transplant clinically practices. Most tissue transplants are rejected due to inflammation however, the cornea has a weaker immune response caused by low antigenicity, the difference between corneal versus other tissue grafts. 7. The mechanisms of ACAID involve both the eye and the spleen. Transforming Growth factor TGF- Ã‚ ¢2 and thrombospondind TSP-1 located in the anterior chamber are involved in the initiation of mediation of ACAID. Through this, there is an attraction of regionally located natural killer T cells, which bind to CDQd molecules to present the antigens. When these cells come in contact with marginal zone B cells, clusters are formed which then differentiate into ACAID-inducing regulatory T cells. 5. A recent discovery made by Molly E. Skelsy and colleagues, concluded that  Ã‚ Ã‚ ¤ T cells are needed for ocular immune privilege and corneal graft survival. The study used mice treated with anti- Ã‚ Ã‚ ¤ Ab failed to develop ACAID concluding the injection of spleen cells. It was concluded that these T cells were required for the creation of regulatory T cells. By blocking the creation of  Ã‚ Ã‚ ¤ T cells, Skelsey showed that there was a profound increase in corneal transplant reje ctions. 8. Another recent discovery was that thymocytes, cells created by thymus that generate into T lymphocytes, are also necessary for the induction of ACAID. Thus the sustainment of immune privilege in the eye is done through the mutual aid of various cells from organs other than the eye itself. 5. The adaptive immunity is expressed in the form of humoral immunity mediated by antibodies produced by B lympocytes, and in the form of cellular immunity mediated by T lymphocytes. 3. (pg 15) Clearly, ocular immune privilege isnt something that just arose out of nowhere. It has been an evolutionary legacy, because whatever beneficial implications it had, leading up to ACAID, must have been immediately beneficial for it to exist throughout the evolution of many mammals such as humans and even mice. In 2008, Xiaoyong Yuan and colleagues did a study to compare the gene expression patterns in uninfected and fungus-infected mouse corneas at the onset of Candida albicans fungal keratitis. Candida ablican related corneal infections cause an inflammatory response, which has been known to permanently impair vision in half of all eyes affected, including those with therapy. Infected eyes were observed and corneal transcriptomes were categorized to suggest pathways contributing to corneal inflammation during Candida related keratitis. Through the use of gene microarray, the hosts gene expression during the early stages of this keratitis was also observed in mouse models. RNA isolated from the corneas one day after inoculation were used for reverse transcription of the RNA which would then be used in a quantitative real-time RT-PCR to multiply the amount of DNA created. Gene expression levels were calculated for both the experimental group and the control group. When comparing the two groups, a total of 45,102 genes were detected. Of those genes, 3,977, roughly 8.82% of the infected corneas were significantly regulated. Of those genes, 1987 were upregulated and 1,990 were down-regulated. A total of 3.71% were differentially expressed, 1,075 being upregulated and the other 597 being down-regulated. Specifically, there were 30 different genes being upreglated more than 100 fold. These genes were categorized as chemokines, metalloproteinases, interleukin cytokines, leukocyte chemotaxis and surface molecules, Ig recept ors, Neuro-hormone mediatiors and many others. Simply stated, these gene expressions suggest that microbial keratitis involves the synchrony of various host processes that affect inflammatory and immune responses, intercellular communication, and cellular metabolism in other words, ocular immune privilege and ACAID. 9. Keratitis is a microbial infliction occurring globally. Bacteria, parasites, virus, and fungus cause the four main microbial causes for infection. These microbes are currently winning the at arms race due to an increased virulence and re-infection after treatment. At the same time, because there have been changes in mans history, various novel environments have been associated with the etiology of all these infections. Looking at a study in a referral centre in South India from September 1999 through August 2002, MJ Bharathi and colleagues observed and calculated the statistics of keratitis in that referral centre. Of 3183 corneal scrapings evaluated, 1095(34.4%) were fungal related, 1043(32.77%) were bacterial related, 33(1.04%) were acanthamoeba related and 76(2.39) were both bacterial and fungal related. Of the 1043 bacterial related infections, the predominant isolated bacteria were Streptococcus. Males were 56.76% of cases and females were 43.24%, thus showing that sex doesnt af fect the infiltration rate. In the study, 60.2% patients were over the age of 50 were affected significantly more than patients under the age of 50. Roughly 16.97% of corneal injuries were due to soil/sand, compared to the 11.03% caused by other materials, showing a statistical significance between the two. Seasons also affected the rate of infections showing a lower incidence of bacterial keratitis from the months of June to September. 10. The epidemiology of bacterial keratitis varies based on geography. One could acquire keratitis from numerous gram-positive or gram-negative bacteria, such as Serratia, Pseudomonas, and Staphylococcus. Once the bacteria has touched base with the cornea, it colonizes the hosts cells by using adhesins at the surface of the epithelium. The adherence of these three bacteria to the corneal epithelium is significantly higher than any other bacteria, which explains their high frequency of isolation. Several bacteria have also displayed adhesins on pili and nonfimbriae structures to recognize carbohydrates on host cells. Recently, there have been emerging cases of resistance among pathogens, requiring the emersion of a stronger antibacterial to eradicate it. 11. The advent of contact lenses has created a novel environment for the infiltration of many bacterial pathogens. In the United States, there are approximately 25,000 cases of infectious keratitis annually. There are roughly 2-4 infections per 10,000 soft contact lenses users, and 10-20 infections per 10,000 extended-wear contact lenses users. 14. A study done by T. Bourcier and colleagues has identified predisposing factors of bacterial keratitis. After analyzing 300 cases, contacts were the main risk factor, occurring in 50.3% of the study group, with 83% of bacteria being gram positive, and 17% being gram negative. 12. Another study of a case report done by Konstantinos Tsaousis and colleagues concluded that the incidence of bacterial keratitis can be reduced by maintaining high standards of lens hygiene and following the recommended guidelines to safely wearing contacts. 13. In the past, fungal keratitis has been a major ophthalmological problem in the tropical regions of the world. 16. Of all of the fungus related to keratitis, there are two classifications of infiltrates yeast and filamentous fungi. The three main isolates of fungus in fungal keratitis are Aspergillus, Fusarium, and Candida. While the most common of isolate reported has been Aspergillus, ranging from 27-64%, Fusarium comes to a close second (6-32%). Like bacterial keratitis, contact lenses wearers are at a higher risk of fungal infection. In recent news, on March 8, 2006, the CDC began an investigation of the use of Bausch Lomb ReNu contact lens solution. The solution had been related to a series of 130 confirmed cases of Fusarium Keratitis, which resulted in 37 corneal transplant surgeries. Most fungal related incidences however are usually related to agriculture. Since fungus are found in soil and on plants, the probability of infection after ocular trauma increases if one is tendi ng to their crops. Once the fungus accesses the corneal stroma, they multiply and cause tissue necrosis leading to the onset of keratitis and the loss of stromal opacity. 15. Acanthamoeba related keratitis is usually derived from standing water or mud, with an increased risk in contact users. Incidence per million contact lens users includes 333 in Hong Kong, 1 in USA and 149 in Scotland 14. The abnormally high incidence in Scotland is due to the fact that there are many water towers, holding standing water, a novel environment for the acanthamoeba. Survival in the wild is not only based on ones ability to escape a predator, but also ones ability to detect the predator. The up keeping the visual axis is one of the most important abilities of the eyes immune abilities for without sight, many mammals would be at disadvantage. Keratitis, the inflammation of the cornea, has probably been around since the dawn of man, and more specifically, the dawn of agriculture. If injury to the eye were to be sustained, the cornea would become inflamed. Normally, corneal cellular layers would be impaired, leading to a loss of the visual axis. However, it has been observed that there is a key mechanism that has developed over time in order to save ones sight. There is an ocular immune privilege, considered to be an evolutionary legacy as well as a design compromise, in the anterior chamber of the eye, which limits certain immune functions to prevent the loss of vision. The microbial pathogens cause these infections ranges from bacterial, to funga l, viral, and amoebic have been detected around the world, causing countless keratitis infections. Novel environments, such as contact lenses, have created the perfect environment for these pathogens to culture on especially if proper care protocols havent been taken. While most of these infections are treatable, in the long term, the microbes are winning the at arms race. With increase resistance to anti-bacterials/fungals, pathogens will only become more virulent. From an epidemiological standpoint, microbial keratitis poses a serious threat for future infected patients, occurring world-wide. Mescher, Anthony L. PhD. (2010).

Sidetracked Movies :: essays research papers fc

Movies have been around for as long as I can remember. They may come in many forms or video types, such as film on a reel, beta, VHS, DVDs and many more. Every successful movie tells a certain story, whether it be original, based on a true story, or based on a book. Whatever the case, the scripts are usually original and closely follow the plot they are based on, if there is one. More recently, unfortunately, movies based on novels are being made closer to the ideas of the screenwriter instead of those of the novel. It is in my opinion that these types of movies should reflect the original works of the authors more closely. One of my personal favourite pieces of literature is the Harry Potter series, written by J.K. Rowling. Naturally, when I heard about the movies being made I was just as excited as any other fan, and I was at the cinema on opening night. I believe Chris Columbus did an awesome job with the movie, keeping the plot moving, introducing the characters, and still including a large majority of the plot in only three hours. The second movie, I thought was even better because everyone knew all the characters already so he could just jump right in with the plot. However, this past couple of years the cast worked with a new director, Alfonso Cuarà ³n, who took the film in a new and possibly worse direction. Not only did Cuarà ³n change the plot around, for example Harry receiving the Firebolt after his encounter with Sirius Black though in the book he received it long before this encounter, but he changed many other things as well. Some of these other changes include the setting, the uniforms , and the characters from J.K. Rowling’s original novels, and from Chris Columbus’ works. Some of the main examples from the third Harry Potter movie include Professor Flitwick, who is described in the book as having â€Å"greying hair.† This is portrayed in the first two movies, however in the third movie Professor Flitwick is portrayed as a small man with a black mushroom cut and a black handlebar moustache. Another point about the third movie that I am very eager to uncover is the origin of the â€Å"maggot heads.† The heads were never mentioned in the third book or any other book for that matter; and were completely made up by the director or screenwriter, possibly to add comedy.

Mental Imagery on Athletic Performance Essay -- Athletics Sports Neuro

Mental Imagery on Athletic Performance What is Mental Imagery? Mental imagery, also called visualization and mental rehearsal, is defined as experience that resembles perceptual experience, but which occurs in the absence of the appropriate stimuli for the relevant perception (plato.stanford.edu/entries/mental-imagery/). Whenever we imagine ourselves performing an action in the absence of physical practice, we are said to be using imagery. While most discussions of imagery focus on the visual mode, there exists other modes of experience such as auditory and kinesthetic that are just as important. However, for the purposes of this paper, only visual imagery will be discussed for it is the most relevant mode concerning athletic performance. Claims Although sports psychology is becoming more prevalent in today’s society, there is a surprising lack of web sites that endorse and offer visual imagery skills for sports. The few advertisements that I found endorse tapes which claim to rapidly improve your athletic skill, concentration, and endurance. Visual imagery advocates purport that this technique increases energy and avoids injuries as well. Not only will visualization improve athletic performance but the ads also claim that it will enhance motivation and overall enjoyment of the sport (www.health-o-rama.org/superlearning/spec-s.htm). Peak Performance Sports looks to sell tapes that has the "latest methods in sports psychology", one of them being mental imagery, which will elevate your game to a new level. The tapes will increase confidence, focus and self-composure which will in turn, improve your athletic performance.

American Government Essay

Introduction There are different ways to which issues in the society can be expressed in relation to emotions, thoughts and artistry. In various eras, movies have been used to tackle issues on religions, philosophies, and even the thoughts and emotions of the writers and directors during the time it is being filmed. For example, the movies entitled Blue Collar, Norma Rae and Roger and Me are movies wherein the problems on employment in any societies have been tackled accordingly. During the time of the creation of the movies, there have been apparent issues with employment that needs to be addressed by the government. Apparently, the theme of conservatism and the plight to destroy it is was the main theme of the three movies mentioned. The motivational principle that has been applied in the course of generating an understanding of the concept of conservatism as highlighted in the movies is sovereignty. It is very elementary to say that in the democratic and liberal forms of government, the sovereign power resides in the people. Under this concept, it cannot be denied that men are only equal before the law and of God. Aside from it, there is no equality. By this, it only means that men are protected only as far as laws and God is concerned. Body Noting this kind of principle is the apparent absence of equality in terms of the social, political and even economic aspects of human being. In terms of the social aspect, it can be seen that men are distinct from women. There is a status quo that should be adhered upon especially when treating men and women. They are not equal under the social order of the society. Men are considered higher in terms of intelligence, capabilities and social status. As per women, they are made to be inside their houses and taking care of the children and of their husbands. It is as if saying that women and men played totally different roles in the society. One is for the house while the other is for the working. Such difference in the social standing of men and women is apparent and to remind people of the principle that aside from law and God, no equality can be measured outside such borders. Women cannot and must not force the society to accept and treat them in the same manner that men are being t reated because it will never be in that way under the conservative theory of governance (Garcia, 2008). The basic foundation of governance that has been tackled in the movies is comprised of the idealism that a just and humane society must be formed. It must be understood that the State should promote a just and dynamic social order. This is accomplished through policies that provide adequate social services. Every society must ensure the prosperity and independence of the nation and free the people from poverty. Hence, it means all people not just the aristocratic few. The goal is to reduce the political and economic power of the privileged few by equalizing widely differing standards and opportunities for advancement and to raise the masses of the people from their poverty to a qualitative life worthy of human dignity. With the eradication of mass poverty being experienced of a nation, the State solves at the same time a chain of social problems that comes with it; social unrest, breakdown of family systems, diseases, ignorance, criminality, and low productivity. Policies must only be created to promote social justice in all phases of national development. In the fulfillment of this duty, the State must give preferential attention to the welfare of the less fortunate members of the community—the poor, the underprivileged and those who have less in life for the benefit of the whole nation. On the issue of economic equality, on the other hand, the movies have made it clear that there are economic differences between the poor and the rich. No equality are being afforded to them. The rich people are getting more privileges in the society as compared to the poor. The poor can never get such privileges because it is just for the rich to experience and enjoy. Since there is no equality, the poor gets poorer with each passing day while the rich gets richer by the hour. There is a distinct role that separates the rich and the poor. While the rich pose as the employers, the poor works as slaves to earn a living. There is equality and hence, no growth and improvement is being afforded to the latter (Funnel, 2009). Conclusion Undeniably, there is an inherent advantage in adopting a development strategy that promotes industrialization and full employment without giving more importance on gender issues. An important aspect of industrializations is that it generates a high level of employment. Factories and industrial sites create job opportunities and thus create sources of livelihood for the people. The high incidence of poverty in the country is rooted in the social scourge that is unemployment. The nation will never recover economically, and social peace and political stability will never come to our land as long as the problem of mass poverty persists. The first step towards the solution of the problem is therefore, the creation of massive work opportunities that will absorb millions of unemployed and underemployed labor in the country, and this can only be done through full and rapid industrialization. But nevertheless, despite the different trajectories that has impacted the lives of the nation and the people inhabiting the place. Ironically, it can be said that whatever the advocates of conservatism have fought for in their lifetimes it has all been gone because of the fact that changes have constantly brought liberalism to the nation. It is one that completely rejects advice or assistance from without. To be realistic, a policy must have global outlook in view of the deleterious effect on the country’s relations with other countries with policies that revolve only on the relations with select members of the international community.

Computer Viruses

A computer virus is an illegal and potentially damaging computer program designed to infect other software by attaching itself to any software it contacts. In many cases, virus programs are designed to damage computer systems maliciously by destroying or corrupting data. If the infected software is transferred to or accessed by another computer system, the virus spreads to the other system. Viruses have become a serious problem in recent years, and currently, thousands of known virus programs exist (Reed 85-102).Three types of viruses are a boot sector viruses, file virus, and Trojan horse virus. A boot sector virus infects the boot program used to start the system. When the infected boot program executes, the virus is loaded into the computer’s memory. Once a virus is in memory, it can spread to any floppy disk inserted into the computer. A file virus inserts virus code into program files. The virus then spreads to any program that accesses the infected file. A Trojan horse v irus (named after the Greek myth) hides within or is designed to look like a legitimate program.Some viruses interrupt processing by freezing a computer system temporarily and then displaying sounds or messages. Other viruses contain time bombs or logic bombs. A time bomb is a program that performs an activity on a particular date. A logic bomb is a program that performs an activity when a certain action occurs, such as an employee being terminated. A worm, which is similar to a virus, copies itself repeatedly until no memory or disk space remains. To detect computer viruses, antivirus programs have been developed.Besides the detecting of the viruses, antivirus programs also have utilities to remove or repair infected programs or files. Some damaged files cannot be repaired and must be replaced with uninfected backup files. The table below outlines some techniques used to protect computer systems. Table Techniques for Virus Protection and System Backup Using Virus Protection Softwar e Backing Up Your System Install virus protection software on every computer system.Develop a regular plan for copying and storing important data and program files. Before use, scan every floppy disk with a virus scan program to check for viruses. Implement a backup plan and adhere to its guidelines. Check all programs downloaded from the Internet or bulletin boards for viruses. Keep backup copies of files in fireproof safes or vaults or off-site If your system becomes virus infected and you have questions, contact the National Computer Security Association (NCSA) for low-cost assistance (Elmhurst, 6 Nov. 1998).

Discovery Rules

Criminal or civil litigation is the last resort for seeking justice from the system. Given the large number of litigation suits filed in democratic countries as the United States, there is a need to seek recompense in justice outside the legal system or before parties concerned agree to bring the issue to a court of law. These measures however need to be institutionalized so that both parties are satisfied with the processes and are encouraged to resolve the matter outside the court of law.The mechanism of discovery rules is one such instrument which has provided for pre-trial phase in a law suit. The discovery procedure allows the parties in a law suit to request for evidence including documents from the other parties. The law provides for making such requests which could be for production as well as depositions. If required sub poenas can be issued for production of evidence. The discovery rules if used purposefully can lead to minimizing litigations as well as provide justice to l itigants.The aim of the prosecution is to collect sufficient evidence to establish veracity of the case and to ensure justice. However frequently the prosecution acts as an instrument to prove guilt of the accused. This mistaken notion results in subverting the very process that is required to be undertaken under the discovery rules. To avoid this anomaly it is essential that the prosecution discloses all evidence to the accused in a criminal case prior to the trial.Having so displayed information in all respects, be it exculpatory or inculpatory by the prosecution, the defendant will be able to establish culpability of the offence and in turn decide either to challenge the case or to disclose as much evidence as possible for the prosecution to assess if the case is to be pursued or will achieve the ends of justice. The defendant is granted very justifiably protection under the Fifth Amendment, a privilege of attorney-client relationship as well as against self recrimination because of which he should not be required to disclose evidence to the prosecution.This ensures that practical problems of implementing discovery rules are overcome. Prosecution can misuse discovery rules to extract maximum evidence regarding the case to strengthen arguments rather than seeking ends of justice. As Stracher (1998) has indicated the best legal minds are involved in manipulation of evidence rather than seeking ends of justice. Thus it would be appropriate for the defendant is able to exercise privileges granted in the present socio-legal environment.

Alliances of Ww1

Intro- Throughout history there has been many conflicts between groups of people that have threatened peace in many nations and regions. One of these conflicts was world war 1 which involved many countries that sided with one another against each other. There were many causes to this conflict that started all the fighting between the nations. Each country has their own view on who's fault it was and if it was handled correctly. This war only caused many casualties and economic problems for countries which could of easily been avoided. 1st paragraph –Alliances were a major cause of the conflicts between countries in WW1 The original disagreement was between Serbia and Austria-Hungry over the assassination of Arch Duke Franz Ferdinand. A Serb terrorist group were the ones to kill Ferdinand even though Austria-Hungry assumed it was the Serbian government who did the assassination. Austria asked Germany if they would back then up in a war if they fought Serbia. This was the start to all of the alliances in Europe. Then Russia told Serbia that they would back them up in war which now 4 countries are involved in the war.The sides ended up with Austria, Germany, and Italy called that central powers. Then they were fighting against the allied powers formed of Great Britain, France, Russia, And the U. S. All of the alliances ended up making this war bigger then many excepted it to be. Also have a reason for countries to build up their army so that they will win the war. Great Britain said that they would make their navy two times stronger then any navy in the world. At the same time the Germans were building up their own army on land. Once they started the war it was almost forgotten what had started the war and why they were fighting.Countries that had nothing to do with Austria and Serbia's disagreement were joining the war just for the chance if winning and gaining more colonies. If the battle only stayed between the Austrians and the Serbs much of this could have been avoided. 2nd paragraph There are many was that you can look at how the the war was played out. One view point of the war was Germany's and its strange how they thought about the war. At the end of the war the Germans were obviously loosing and there was no way of getting out of it. Although at the same time Woodrow Wilson had thought up the 14 points.These were rules / laws to what would happen once the war was over. Some of it stated that no one would be called the â€Å"loser† of the war. Germany was obviously happy with this because now they just got out of loosing a war badly. Also it stated everyone would lose their colonies and no one would have anymore. This was also great for Germany because they were going to lose their colonies either way, but now that other countries lose them also thats a little better. All the countries got together to discuss about the 14 points and other things forming the treaty of Versailles.Once they started discussing about the tr eaty it did not look good for Germany. In the treat it says Germany will get its colonies taken away and given to France and Great Britain. They were unhappy cause the 14 points said no one has colonies. The treaty also made Germany pay war reparations to many of the countries with great loss. The Germans did not have much money after the war to begin with and now are forced to pay money to nations who fought against them. Finally Germany had to take blame for all of WW1 which was a bit extreme the Germans thought.There are many countries that contributed to WW1 and to put all the blame on Germany's shoulders did not seem right to them. That was the biggest upset to the Germans that they were blamed for the war even though they did the same thing as the other countries in the war. 3rd paragraph – In war there are 2 different stories to the side of the war. Great Britain in the war was going against the Germans and their view point was different. Britain were the ones winning the war before it was ended. The U. S. joined in at the end securing the victory for the allied powers.Woodrow Wilson brought his idea of the 14 points to Europe which Great Britain disliked. They did not like the 14 points because they would not be given credit for wining the war. Great Britain believed that since they won the war the credit should go to them, it would only be fair. Under the 14 points it also say's that there will be no more colonies. Great Britain was excepting more colonies for them since they had won the war. This is a surprise to Britain and did not like the ideas that Woodrow Wilson had came up with.When they treaty of versailles was composed the laws were very different. Germany was blamed for the war which was implying that Germany were the losers of the war. The treaty was also intended to take away colonies except Great Britain and France were able to keep their own. This was because they were the ones composing the treaty and made it good for themselves. It turned out that since Great Britain was such a major power in Europe that they made the rules. They were the ones making the decisions at the resolution of WW1. 4th-pargraphAt the end of WW1 many countries were still uneasy with the outcome of the war. The treat to end the war was called the treaty of Versailles and this decided how the end of the war would be concluded. The conflict between the countries was definitely not resolved, there were many countries dissatisfied after the war ended. Many of these countries were upset because of how the treaty of Versailles was made up. The only two countries satisfied with the treaty were Great Britain and France because they decided what would be in it.For a fair treaty you should have all of the countries that would be involved in the meeting. Leaving nations such as Germany out of the meeting causes them to get angry and most likely disobey the treaty. If all countries were allowed to attend the meeting and speak their own opinion. This war could have been settled in a more organized fashion that would have avoid any countries being agervated. I do not think this war was resolved, but easily could have if the right choices were made during makeing the treaty of Versailles.Conclusion – History has had its many conflicts between groups of people that have disagreed with each other . The conflicts of world war 1 which we're mainly caused by alliances nations made with one another. Many reasons lead to the fighting of world war 1 . At the end of the war if the treaty that settled the fighting was fair less countries would still be unhappy . Once World War 1 ended the death and destruction that came about was incredible , all could have been avoided with more precautions.

In fact, the creation of many outlets in an area reduced the incomes of the outlets by sharing the market among the outlets. The faster rate of growth was affected by the global financial crisis which affected the buying power of the consumers. The development of a strong brand presence and image improved its market share. The green and white package makes Starbucks product identification simple and attractive (Allen, 2010, p. 56).
