My Writing Poetry By Sylvia Plath - 1106 Words

My words were alive. They spilled out from my mouth and enveloped the crowded room. Waves of metaphors and stanzas washed over and between the audience, whose heads jutted out over the backs of their blackwood table chairs like coral. As I spoke, I felt that I was no longer myself, but something bolder, fearless and fiercely honest. A vessel possessed by the words I had spent months poring over. Spoken word poetry gave me the courage to express myself. Growing up, I had always been shy and awkward. In school, I would rather spend my time daydreaming than talking to classmates. When I was forced to socialize, whether it be by teachers or my parents, it was usually met with stammering, sweat and downturned eyes. As a result, I had trouble†¦show more content†¦I was ecstatic; someone actually thought my writing was good! I kept emailing her poetry, and, with her encouragement, signed up for a teen spoken word competition. I had only a month to practice before the qualifying bout, and I had never read any of my poems aloud. Needless to say, I was panicked. I spent hours reciting poetry to my hardwood bedroom door. Each word stuck in my throat like syrup and took too much effort to spit out. By the time I had finished reciting one stanza, long lines of sweat were slipping down my forehead and over my lips. My mouth was a desert, occasionally battered with drops of musky saltwater. I took breaks in between stanzas to catch my breath and wipe the sweat off my face. During these tumultuous practice sessions, I began to regret agreeing to sign up for the competition. Regardless of my worries, the day of the qualifying bout eventually came. The bout took place in the backroom of a cafe. It was a small space, and people crowded the square mahogany tables scattered throughout the brightly lit room. An odd combination of coffee, pizza and alcohol mingled in the air, and a five-foot long stage covered in oriental carpeting was situated in the front of the room. After registering, I made my way to an area near the stage reserved for competitors. Some of the competitors were engaged in conversations with each other, while others recited their poems under their breaths.

Network Management in Organization for Cyber-myassignmenthelp

Question: Discuss about theNetwork Management in Organization for Cyber Stalking. Answer: Introduction The excessive utilization of the internet for every small to big concept results into the cyber-crime activities. The cyber-criminals are looking opportunity for hacking, theft, and malicious activity. The cyber-crimes activities mainly focus on damaging the confidentiality of information and adding malwares to the software program. These are the illegal activities which can violate the laws enforcement for damaging the effective functioning of the cyber-environment. The adverse effect on the society can be seen due to the increasing growth of cyber-piracy, internet pornography, and cyber-stalking. The cyber task force should be created for developing new policies and procedures framework to secure the society from the cyber-attacks. The cyber task force works with the association of law enforcement agencies to develop effective laws and legal obligations to cope up with the cyber-attack problems. Research Aim In this paper we are looking forward to analyse the cyber-attacks which are responsible for adversely affecting the society such as cyber-piracy, internet pornography, and cyber stalking. The focus should be given on the research carried on the development of cyber task force to develop legal obligation with the association of the law enforcing agencies. The research should be carried on analysing the working and effectiveness of the cyber task force. Research Objective The objective of this paper is to review the literature on cyber-crime and its impact on the society. The focus should be given on the target audience which get affected due to the illegal activities of cyber-environment. The research should be carried on analysing the working and effectiveness of the cyber task force. The development of the legal obligations helps to minimize the problem of cyber-attack on society. Literature Review The literature review was conducted on the cyber-crime to initialize the impact on society. The increasing growth of internet and its related application creates a new opportunity for the hacker to theft the information and data from the customers accounts. The cyber-piracy, cyber-stalking, and internet pornography have negatively affect the society. The cyber piracy is the copyright material related to music, recordings, movies, and others. The market value of the original videos, recordings, audios, and music is devaluated due to the increasing activity of cyber-piracy. The people get attracted towards the movies and music at minimum cost which give confidence to the pirates to develop more and more pirated copies of the material without the permission of the owner. The cyber-stalking had a direct impact on the psychological status of the people. The spreading of rumours, identity thefts, defamation, and others on the internet can harness the mental condition of the victim and made him compel to take suicidal action. The cyber-stalking threatened the life of the victim by spreading false rumours about his image in the society. The major cases are heard of suicide by the youngster due to the defamation of image on the internet. The behaviours of the individuals are moving towards the sexual activities due to the inclusion of internet pornography. The internet pornography makes a direct impact on the human behaviour towards the sexual aggression. It give rise to sexual molestation and rape cases in the society. It arouses the feeling of sex which results into the violation of women. From the research conducted on the Australian government, it is found that the government has taken subsequent steps to develop laws for minimizing the cyber-crime impact on society. The US Government has taken action for developing a cyber-security task force to fight against increasing growth of cyber threat at global level. The task force is comprised of various people from justi ce department and federal agencies to take effective decision against the people who are working in the field of cyber-crimes. The task force is designed for maintaining records of the cyber-crime activities and grapping the concern person who took part in the cyber-crime activities. The cyber digital task force develop various tools for to grab the criminals and develops the mitigate plans to protect the society from criminal activities. The awareness messages are released from the authorities not the react with the fake accounts, do not provide any secret information through the online portal, and others. The personal details and confidential information should not be handed to the unknown third party because it can open the chance for cyber-stalking. The piracy of the movies should be banned without having a copyright ace from the owner. The internet pornography sites should be banned for the individual who are below the age of 18 years. The open accessing of the pornography site s should be omitted to the individual. It has been viewed that the development of the task force can prtect the society from the increasing growth of cyber-crime which is having the direct impact on the individual psychological status. Methodology The qualitative methodology is undertaken to collect the data on the types of cyber-crimes and their adverse effect on society. The online and offline tools are used to collect effective data for research on cyber-attack and its impacts. Interview: The interview is conducted with the IT professional to give their perspective view on the designed research questions which are developed to get details about cyber-stalking, internet pornography, and cyber piracy and their impact on the society. The professional shared their views on the increasing growth of cyber-crime and anomalies which occurred in the work environment. Questionnaire: The group of IT experts, society leaders, and students are gathered together to present their views on the listed questions about the cyber-crime and its impact. The different perspectives views of the group members are noted down in the well-developed format. Literature Review: The study of the literature review helps in identifying the cyber-crimes which directly affect the growing generation of society. The theoretical framework of the literature review helps in analysing the facts and figures about the cyber-crimes and its consequences on the society. Online Sources: The reading of the e-magazines, news, and participation in the online chat session helps in identifying the new facts and research carried out in the field of cyber-crimes with respect to society. Discussion and Analysis The research study helps in analysing that a strict action should be taken to ban the growth of cyber-crime and its associated impact on the society. The national government of the countries should develop their cyber digital task force similar to the Australia and United states to protect the dignity of the individual against the impact of cyber-crime. The awareness programs should be arranged for providing the guidance to the citizen about using the internet services and protect themselves from the attacks of the cyber-stalking. The people should deny using the pirated music and videos. The concentration of the individual in carrying out their activities can be disturbed with the internet pornography and they cannot provide their capabilities and expertise to the required work. The individual should be guided to the negative impact of the pornography websites on the psychological status of the mind. The respect should be given to the women. The cyber digital task force develop vari ous tools for to grab the criminals and develops the mitigate plans to protect the society from criminal activities. The new policies framework should be developed regarding the banning of cyber-piracy and internet pornography websites. Conclusion From the research study, it is concluded that individual should be careful about using the internet services and does not provide their confidential information to the unknown third party. The awareness programs should be arranged for providing the guidance to the citizen about using the internet services and protect themselves from the attacks of the cyber-stalking. References: [1]C.

The day had come; it was the Tennis Championship Finals. All I could remember at that time was all the hard work I had possessed in order reach this point, a point where all the high schools in New York City want to be. And most of my fear at this point was whether I could win the championship or lose it all. It wasn’t just me playing for that championship trophy, it was the entire team, so the pressure was on all of us and I could feel it, as my nerves were moving in all directions giving me goosebumps. My teammates and I had thirty minutes free time before the game, so we got together with our coach, loosened up, took pride in ourselves and looked at the past and what we had accomplished, and set our minds to the championship game and put all of our focus in to it.

We were still in focus to meet our opponents and were completely ready to take the trophy back to our school. We called ourselves the Beavers and stepped into the courts as warriors and put ourselves in the battlefield. The game started and I was playing the game at my best with a fierce spirit to win, and so did all my teammates. But unfortunately for me, my opponent seemed to be more skilled and tenacious. With my nervousness pulling me back, I was only able to win one set out of the three sets that were played. The game came to an abrupt end and my adversary had won the game by two sets and defeated me. And what were my feelings? I felt like killing myself. I cursed, yelled even let some tears run out of my eyes, but in the end it was no hope, and I realized that my adversary was just too good for me. My teammates cheered me up and said â€Å"it’s ok, you did your best† but that didn’t soothe me at all. I knew I could have done better. In the end, we didn’t win the championship but still were able to retrieve the runner up trophy. As a team, we realized it’s not about winning the championship that matters the most, what matters was the hard work, experience, and the fun we had in preparing for this one moment since the season begun. I might not have won the match, but I was not ashamed of it. Instead, I was proud of my accomplishments and was also proud to be part of the Jamaica Tennis Team. As elders say, There are many things that need to be learned in life and my lesson is that as an athlete either you win or lose but don’t ever regret anything that you did, always feel good about yourself and take the lesson of losing and turn it into winning. It doesn’t matter whether I lost the championship last season. But this time, it’s a new season, new game, different tactics but one same goal.

Public Health Essays

Public Health Essays Public Health Paper Public Health Paper Public health is the science and art of protecting and improving the health of communities through education, promotion of healthy lifestyles, and research for disease and injury prevention. Public health is concerned with protecting the health of entire populations. These populations can be as small as a local neighborhood, or as big as an entire country. Public health can make a difference in the lives of tens, hundreds, and even thousands or millions. Public health program is very important beause these are some of the threats to our health that we will be facing in the years to come such as avian influenza, HIV/AIDS, obesity, cancer, bioterrorism, domestic violence, substance abuse, mental health, drug resistant diseases, emerging and re-emerging diseases, environmental toxins, inequities in health care access and manymore. Most experts agree that these problems cant be tackled with new medical findings or cures; it is up to public health to protect us from these threats. Seeing the health problems such as highly increasing of disease prevalence, public health offers the best solution program because public health is a very diverse and dynamic field incorporating many disciplines that consist of biology, sociology, mathematics, anthropology, public policy, computer science, business, environmental science, communications, etc. 2. 1 Early public health interventions o 2. 2 Modern public health + 2. 2. 1 Public Health 2. 0 * 3 Education and training o 3. 1 Schools of public health o 3. 2 Degrees in public health * 4 Public health programs o 4. 1 Applications in healthcare * 5 See also * 6 References * 7 Further reading * 8 External links [edit] Objectives The focus of a public health intervention is to prevent and manage diseases, injuries and other health conditions through surveillance of cases and the promotion of healthy behaviors, communities and environments. Many diseases are preventable through simple, non-medical methods. For example, research has shown that the simple act of hand washing with soap can prevent many contagious diseases. [4] In other cases, treating a disease or controlling a pathogen can be vital to preventing its spread to others, such as during an outbreak of infectious disease, or contamination of food or water supplies. Public health communications programs, vaccination programs, and distribution of condoms are examples of common public health measures. Public health plays an important role in disease prevention efforts in both the developing world and in developed countries, through local health systems and non-governmental organizations. The World Health Organization (WHO) is the international agency that coordinates and acts on global public health issues. Most countries have their own government public health agencies, sometimes known as ministries of health, to respond to domestic health issues. For example in the United States, the front line of public health initiatives are state and local health departments. The United States Public Health Service (PHS), led by the Surgeon General of the United States, and the Centers for Disease Control and Prevention, headquartered in Atlanta, are involved with several international health activities, in addition to their national duties. In Canada, the Public Health Agency of Canada is the national agency responsible for public health, emergency preparedness and response, and infectious and chronic disease control and prevention. In India, the Public Health Foundation of India was launched in 2006 as a response to growing concern over the emerging public health challenges in that country. There is a vast discrepancy in access to health care and public health initiatives between developed nations and developing nations. In the developing world, public health infrastructures are still forming. There may not be enough trained health workers or monetary resources to provide even a basic level of medical care and disease prevention. [5] As a result, a large majority of disease and mortality in the developing world results from and contributes to extreme poverty. For example, many African governments spend less than USD$10 per person per year on health care, while, in the United States, the federal government spent approximately USD$4,500 per capita in 2000. [edit] History of public health In some ways, public health is a modern concept, although it has roots in antiquity. From the beginnings of human civilization, it was recognized that polluted water and lack of proper waste disposal spread communicable diseases (theory of miasma). Early religions attempted to regulate behavior that specifically related to health, from types of food eaten, to regulating certain indulgent behaviors, such as drinking alcohol or sexual relations. The establishment of governments placed responsibility on leaders to develop public health policies and programs in order to gain some understanding of the causes of disease and thus ensure social stability prosperity, and maintain order. The term healthy city used by todays public health advocates reflects this ongoing challenge to collective physical well-being that results from crowded conditions and urbanization. [edit] Early public health interventions Public health nursing made available through child welfare services in U. S. (c. 1930s) By Roman times, it was well understood that proper diversion of human waste was a necessary tenet of public health in urban areas. The Chinese developed the practice of variolation following a smallpox epidemic around 1000 BC. An individual without the disease could gain some measure of immunity against it by inhaling the dried crusts that formed around lesions of infected individuals. Also, children were protected by inoculating a scratch on their forearms with the pus from a lesion. This practice was not documented in the West until the early-18th century, and was used on a very limited basis. The practice of vaccination did not become prevalent until the 1820s, following the work of Edward Jenner to treat smallpox. During the 14th century Black Death in Europe, it was believed that removing bodies of the dead would further prevent the spread of the bacterial infection. This did little to stem the plague, however, which was most likely spread by rodent-borne fleas. Burning parts of cities resulted in much greater benefit, since it destroyed the rodent infestations. The development of quarantine in the medieval period helped mitigate the effects of other infectious diseases. However, according to Michel Foucault, the plague model of governmentality was later controverted by the cholera model. A Cholera pandemic devastated Europe between 1829 and 1851, and was first fought by the use of what Foucault called social medicine, which focused on flux, circulation of air, location of cemeteries, etc. All those concerns, born of the miasma theory of disease, were mixed with urbanistic concerns for the management of populations, which Foucault designated as the concept of biopower. The German conceptualized this in the Polizeiwissenschaft (Science of police). The science of epidemiology was founded by John Snows identification of a polluted public water well as the source of an 1854 cholera outbreak in London. Dr. Snow believed in the germ theory of disease as opposed to the prevailing miasma theory. Although miasma theory correctly teaches that disease is a result of poor sanitation, it was based upon the prevailing theory of spontaneous generation. Germ theory developed slowly: despite Anton van Leeuwenhoeks observations of Microorganisms, (which are now known to cause many of the most common infectious diseases) in the year 1680, the modern era of public health did not begin until the 1880s, with Louis Pasteurs germ theory and production of artificial vaccines. Other public health interventions include latrinization, the building of sewers, the regular collection of garbage followed by incineration or disposal in a landfill, providing clean water and draining standing water to prevent the breeding of mosquitoes. This contribution was made by Edwin Chadwick in 1843 who published a report on the sanitation of the working class population in Great Britain at the time. So began the inception of the modern public health. The industrial revolution had initially caused the spread of disease through large conurbations around workhouses and factories. These settlements were cramped and primitive and there was no organised sanitation. Disease was inevitable and its incubation in these areas was encouraged by the poor lifestyle of the inhabitants. [edit] Modern public health With the onset of the epidemiological transition and as the prevalence of infectious diseases decreased through the 20th century, public health began to put more focus on chronic diseases such as cancer and heart disease. Previous efforts in many developed countries had already led to dramatic reductions in the infant mortality rate using preventative methods. For instance in the United States, public health worker Dr. Sara Josephine Baker established many programs to help the poor in New York City keep their infants healthy, leading teams of nurses into the crowded neighborhoods of Hells Kitchen and teaching mothers how to dress, feed, and bathe their babies. During the 20th century and early in the next, the dramatic increase in average life span is widely credited to public health achievements, such as vaccination programs and control of many infectious diseases including polio, diphtheria, yellow fever and smallpox; effective health and safety policies such as road traffic safety and occupational safety; improved family planning; tobacco control measures; and programs designed to decrease non-communicable diseases by acting on known risk factors such as a persons background, lifestyle and environment. One of the major sources of the increase in average life span in the early 20th century was the decline in the urban penalty brought on by improvements in sanitation. These improvements included chlorination of drinking water, filtration and sewage treatment which led to the decline in deaths caused by infectious waterborne diseases such as cholera and intestinal diseases. In Cutler and Millers, The Role of Public Health Improvements in Health Advances, they display evidence of the decline in typhoid fever deaths in Chicago, Baltimore, Cincinnati, and Cleveland after these American cities adopted chlorination, filtration, or a sewage improvement. [6] Meanwhile, large parts of the developing world remained plagued by largely preventable/treatable infectious diseases and poor maternal and child health outcomes, exacerbated by malnutrition and poverty. The WHO reports that a lack of exclusive breastfeeding during the first six months of life contributes to over a million avoidable child deaths each year. [7] Intermittent preventive therapy aimed at treating and preventing malaria episodes among pregnant women and young children is one public health measure in endemic countries. Front-page headlines continue to present society with public health issues on a daily basis: emerging infectious diseases such as SARS, making its way from China (see Public health in China) to Canada, the United States and other geographically distant countries; reducing inequities in health care access through publicly funded health insurance programs; the HIV/AIDS pandemic and its spread from certain high-risk groups to the general population in many countries, such as in South Africa; The increase of childhood obesity and the concomitant increase in type II diabetes among  children; the social, economic and health impacts of adolescent pregnancy; and the ongoing public health challenges related to natural disasters such as the 2004 Indian Ocean tsunami, 2005s Hurricane Katrina in the United States and the 2010 Haiti earthquake. Since the 1980s, the growing field of population health has broadened the focus of public health from individual behaviors and risk factors to population-level issues such as inequality, poverty, and education. Modern public health is often concerned with addressing determinants of health across a population. There is a recognition that our health is affected by many factors including where we live, genetics, our income, our educational status and our social relationships these are known as social determinants of health. A social gradient in health runs through society, with those that are poorest generally suffering the worst health. However even those in the middle classes will generally have worse health outcomes than those of a higher social stratum. [8] The new public health seeks to address these health inequalities by advocating for population-based policies that improve health in an equitable manner. [edit] Public Health 2. 0 Public Health 2. 0 is the term given to a movement within public health that aims to make the field more accessible to the general public and more user-driven. There are three senses in which the term Public Health 2. 0 is used. In the first sense, Public Health 2. 0 is similar to the term Health 2. 0 and is used to describe the ways in which traditional public health practitioners and institutions are reaching out (or could reach out) to the public through social media. [9][10] In the second sense, Public Health 2.0 is used to describe public health research that uses data gathered from social networking sites, search engine queries, cell phones, or other technologies. [11] In the third sense, Public Health 2. 0 is used to describe public health activities that are completely user-driven. [12] An example this type of Public Health 2. 0 is the collection and sharing of information about environmental radiation levels following the March 2011 tsunami in Japan. [13] In all cases, Public Health 2. 0 draws on ideas from Web 2. 0, such as crowdsourcing, information sharing, and user-centred design. [14] [edit] Education and training Education and training of public health professionals is available throughout the world in Medical Schools, Schools of Public Health, and Schools of Public Affairs. The training typically requires a university degree with a focus on core disciplines of biostatistics, epidemiology, health services administration, health policy, health education, behavioral science and environmental health. [15][16] Many other programs, such as in nursing or dietetics, include some public health content even if not specifically designed to prepare for a profession in public health. [edit] Schools of public health In the United States, the Welch-Rose Report of 1915 has been viewed as the basis for the critical movement in the history of the institutional schism between public health and medicine because it led to the establishment of schools of public health supported by the Rockefeller Foundation. [17][18] The report was authored by William Welch, founding dean of the Johns Hopkins Bloomberg School of Public Health, and Wycliffe Rose of the Rockefeller Foundation. The report focused more on research than practical education. [17][19] Some have blamed the Rockefeller Foundations 1916 decision to support the establishment of schools of public health for creating the schism between public health and medicine and legitimizing the rift between medicines laboratory investigation of the mechanisms of disease and public healths nonclinical concern with environmental and social influences on health and wellness. [17][20] Even though schools of public health had already been established in Canada, Europe and North Africa, the US had still maintained the traditional system of housing faculties of public health within their medical institutions. However, a year following the Welch-Rose report, the Johns Hopkins School of Hygiene and Public Health was founded in 1916. By 1922, schools of public health were established in Columbia, Harvard and Yale universities. By 1999 there were twenty nine schools of public health in the US, enrolling around fifteen thousand students. [17][15] Over the years, the types of students and training provided have also changed. In the beginning, students who enrolled in public health schools typically had already obtained a medical degree; public health school training was largely a second degree for medical professionals. However, in 1978, 69% of American students enrolled in public health schools had only a bachelors degree. [15] [edit] Degrees in public health Main article: Professional degrees of public health Schools of public health offer a variety of degrees which generally fall into two categories: professional or academic. [21] The two major postgraduate professional degrees are the Master of Public Health (MPH) or the Master of Science in Public Health (MSPH). Doctoral studies in this field include Doctor of Public Health (DrPH) and Doctor of Philosophy (PhD) in a subspeciality of greater Public Health disciplines. DrPH is regarded as a professional leadership degree and PhD is more an academic degree. Professional degrees are oriented towards practice in public health settings. The Master of Public Health, Doctor of Public Health, Doctor of Health Science (DHSc) and the Master of Health Care Administration are examples of degrees which are geared towards people who want careers as practitioners of public health in health departments, managed care and community-based organizations, hospitals and consulting firms among others. Master of Public Health degrees broadly fall into two categories, those that put more emphasis on an understanding of epidemiology and statistics as the scientific basis of public health practice and those that include a more eclectic range of methodologies. A Master of Science of Public Health is similar to an MPH but is considered an academic degree (as opposed to a professional degree) and places more emphasis on quantitative methods and research. The same distinction can be made between the DrPH and the DHSc. The DrPH is considered a professional degree and the DHSc is an academic degree. Academic degrees are more oriented towards those with interests in the scientific basis of public health and preventive medicine who wish to pursue careers in research, university teaching in graduate programs, policy analysis and development, and other highs of academic degrees are the Master of Science, Doctor of Philosophy, Doctor of Science (ScD), and Doctor of Health Science (DHSc). The doctoral programs are distinct from the MPH and other professional programs by the addition of advanced coursework and the nature and scope of a dissertation research project. In the United States, the Association of Schools of Public Health[22] represents Council on Education for Public Health (CEPH) accredited schools of public health. [23] Delta Omega is the honorary society for graduate studies in public health. The society was founded in 1924 at the Johns Hopkins School of Hygiene and Public Health. Currently, there are approximately 68 chapters throughout the United States and Puerto Rico. [24] [edit] Public health programs Today, most governments recognize the importance of public health programs in reducing the incidence disease, disability, and the effects of aging and other physical and mental health conditions, although public health generally receives significantly less government funding compared with medicine. [25] In recent years, public health programs providing vaccinations have made incredible strides in promoting health, including the eradication of smallpox, a disease that plagued humanity for thousands of years. The World Health Organization (WHO) identifies core functions of public health programs including:[26] * providing leadership on matters critical to health and engaging in partnerships where joint action is needed; * shaping a research agenda and stimulating the generation, translation and dissemination of valuable knowledge; * setting norms and standards and promoting and monitoring their implementation; * articulating ethical and evidence-based policy options; * monitoring the health situation and assessing health trends. In particular, public health surveillance programs can:[27] * serve as an early warning system for impending public health emergencies; * document the impact of an intervention, or track progress towards specified goals; and * monitor and clarify the epidemiology of health problems, allow priorities to be set, and inform health policy and strategies. Public health surveillance has led to the identification and prioritization of many public health issues facing the world today, including HIV/AIDS, diabetes, waterborne diseases, zoonotic diseases, and antibiotic resistance leading to the reemergence of infectious diseases such as tuberculosis. Antibiotic resistance, also known as drug resistance, was the theme of World Health Day 2011. For example, the WHO reports that at least 220 million people worldwide suffer from diabetes. Its incidence is increasing rapidly, and it is projected that the number of diabetes deaths will double by the year 2030. [28] In a June 2010 editorial in the medical journal The Lancet, the authors opined that The fact that type 2 diabetes, a largely preventable disorder, has reached epidemic proportion is a public health humiliation. [29] The risk of type 2 diabetes is closely linked with the growing problem of obesity. The WHO’s latest estimates highlighted that globally approximately 1. 5 billion adults were overweight in 2008, and nearly 43 million children under the age of five were overweight in 2010. [30] The United States is the leading country with 30. 6% of its population being obese. Mexico follows behind with 24. 2% and the United Kingdom with 23%. Once considered a problem in high-income countries, it is now on the rise in low-income countries, especially in urban settings. Many public health programs are increasingly dedicating attention and resources to the issue of obesity, with objectives to address the underlying causes including healthy diet and physical exercise. Some programs and policies associated with public health promotion and prevention can be controversial. One such example is programs focusing on the prevention of HIV transmission through safe sex campaigns and needle-exchange programmes. Another is the control of tobacco smoking. Changing smoking behavior requires long term strategies, unlike the fight against communicable diseases which usually takes a shorter period for effects to be observed. Many nations have implemented major initiatives to cut smoking, such as increased taxation and bans on smoking in some or all public places. Proponents argue by presenting evidence that smoking is one of the major killers, and that therefore governments have a duty to reduce the death rate, both through limiting passive (second-hand) smoking and by providing fewer opportunities for people to smoke. Opponents say that this undermines individual freedom and personal responsibility, and worry that the state may be emboldened to remove more and more choice in the name of better population health overall. Simultaneously, while communicable diseases have historically ranged uppermost as a global health priority, non-communicable diseases and the underlying behavior-related risk factors have been at the bottom. This is changing however, as illustrated by the United Nations hosting its first General Assembly Special Summit on the issue of non-communicable diseases in September 2011. [31] [edit] Applications in healthcare As well as seeking to improve population health through the implementation of specific population-level interventions, public health contributes to medical care by identifying and assessing population needs for health care services, including:[32][33][34][35] * Assessing current services and evaluating whether they are meeting the objectives of the health care system * Ascertaining requirements as expressed by health professionals, the public and other stakeholders * Identifying the most appropriate interventions * Considering the effect on resources for proposed interventions and assessing their cost-effectiveness * Supporting decision making in health care and planning health services including any necessary changes.

SDS PAGE - Term Paper Example -mecaptoethamol prevents oxidation of cysteines and break up disulphide bonds, Bromophenyl dye is used to help in visualizing the sample as it travels across the gel and glycerol is added to make the sample fall to the bottom. (Leamlli, 1970). Electric charge is applied across the gel to influence the movement of protein molecules to positively charged end. Principal behind SDS PAGE The structure of protein molecules to be separated has portions of negative and positive charges resulting from charged R-groups of particular amino acid and hydrophobic portions of nonpolar R-groups hence difference in shapes and sizes of protein molecules. (Hempelmann, 2008) Therefore, the first stage of SDS PAGE is to make the protein molecules linear and to ensure that there are no secondary, tertiary, or quaternary molecular structures in the sample. This is achieved by injecting the sample with SDS, which is a detergent that can dissolve the membrane and solubilise the protein molecules. Its negativ e charge overcome positive charges of protein molecules. The resulting protein is denatured, linearized, and negatively charged. The next stage in SDS PAGE is the separation process. This is based on the molecular size and weight of the molecules, sieving properties of the gel is of great assistance at this stage since protein molecules have the same charge-to-mass-ratio. The gel is not a solid but made up of series of tunnel of different diameters running from one end to the other and are scattered through the gel. (SDS PAGE, 2009) Velocity of particles moving through an electric field is directly proportional to strength of the electric field and degree of charge in the particle but inversely proportional to size of the particles and viscosity of the medium. This is the basis upon which protein of different sizes are separated. (SDS PAGE. 2009). The discontinuous pH parts of the gel come handy in aligning the proteins properly at the starting point. Laemmli gel is composed of stac ker and running gel, the running gel is buffed with Tris to pH of 8.8 with HCl; stacker gel is adjusted with Tris to pH 6.8 with HCl. The electrode buffer is adjusted to pH 8.3 using glycine and the gel is then run at a constant voltage. (Leamlli, 1970) When the power is switched on, glycine (which is a weak acid and can exist in an uncharged state as zwitterions at low pH, or in a charged state as glycinate anion at high pH) ions in the running buffer wants to move away from the negative electrode towards the sample and the stacking gel. The pH in stacking gel is low and so glycin ions lose their charge and slow down. In the stacker and sample, negatively charged mobile chloride ions move away from the cathode creating a narrow zone of very low conductance (very high electrical resistance) in the top of the stacking gel. Almost all the applied voltage is concentrated in this small zone. The very high field strength makes the negatively charged proteins to move forward. The trick, h owever, is that they can never outrun the chloride ions. If they did, they would find themselves in a region of high conductance and very low field strength and would immediately slow down. The result is that all the proteins move through the stacker in a tight
