Genetically Modified Foods Essay
Introduction The world is slowly running out of food. Impoverished people have nowhere to turn. Biotechnology researchers think they have found a way to reverse the world famine. This way is through genetically modified foods which are foods that come from genetically engineered organisms. Examples of such organisms are sheep, cows, and fish. However, since it is a new invention, it is being met with harsh and legitimate concerns. While it may help the worldââ¬â¢s food crisis, it may also do that at the expense of human health. Moreover, In the 90ââ¬â¢s in the USA, the Food and Drug Administration decided that genetically modified food was safe and did not require special regulation. They stated that is was, ââ¬Å"not inherently dangerous. â⬠(FDA, 1998). This allowed genetically modified food such as soybean oils and tomatoes to enter the market. There are lots of ideas about the GMF. Some scientists say that it is no harmful affects of GMF and it may be a solution for scarcity of food and even it is healthy. However, some others say that GMFs are dangerous for public health. And It can damage biodiversity. Genetically modified foods may be a good solition to increase the amount of food. The problem is there are lots of people go to sleep hungry everyday and the number of hungry people is getting bigger. And International Food Policy Research Institute state there are ââ¬Å"120 devoloping countriesâ⬠which are very close to limit of hunger and ââ¬Å"57 of which with a serious or worse hunger situation. â⬠(Global Hunger Index, 7) The reason of this hunger is there is not enough food to feed them and because the world population is getting higher but the areas which use in farming are getting smaller. Farmers could not find suitable area to plant their crops. That is why, They have to find a different solution to be productive. Conko argues that biotech agriculture is the method by which we can increase agricultural productivity without resorting to increases in harmful chemical fertilizers, herbicides, and pesticides. In the Genetic Modification it says that genetic modification provides a means to confer resistance to broad-spectrum herbicides into crops where current weed control is considered difficult. In this way, farmers can be more productive and they can get more product on their fields. ââ¬Å"In the United States, in 2002 about 5. 5 million farmers in 145 nations were planting more than 145 million acres worth of GM crops. â⬠(Conko) On the other hand, genetically modified herbicide tolerant crops might have a negative impact on biodiversity. Genetically Modified crops have an impact on birds and insect. A crop plant modified to be toxic to insect pests can have a direct harmful effect on non-target insects if they eat the plant. It can also have an indirect effect by reducing the insects that are a food source for other wildlife, such as farmland birds. Genetically Modified crops that are tolerant to herbicides could also lead to a reduction in weed populations that act as refuges for beneficial insects, and those that are eaten by birds. This process takes time because of this GM crops evaluate as a good solution but it can destroy the biological diversity. And US conservation organization Royal Society,founded in London In 1660 is a learned society for science, support it. They state that the likelihood of the spread of Genetically modified into the wild populations, the risk of superweeds being produced, the impact Genetically modified introductions might have on the colonies of micro organisms living in the soil and how such risks can be assesed and analysed. Also John Innes Centre, Founded in England is an independent centre for research and training in plant and microbial science, state that Monarch butterfly larvae fed only on leaves covered in pollen from Bt corn grew more slowly and suffered higher death rates and pink bollworm fed on cotton producing the Bt toxin. Aphids fed on Genetically Modified potatoes producing a different toxin were also reported to have a harmful effect on ladybirds feeding on the aphids. Genetically Modified crops can be beneficial for health in terms of their food value. Foods include lots of vitamins which are necessary to our body. In early days, our foods were full of vitamins, proteins, carbohydrate and they were occupied with value. However, now there are not enough foods which are full of value. Because there are lots of environmental factors like global warming which causes to summers takes long time, and scarcity of water, and also some pests. These factors effect the crops and farmers have to use pesticide and this cause to decrease food value. And it leads lots of health problems. And the one of the most important health problem is Vitamin A deficiency. This is the cause of at least ââ¬Å"1 million childhood deathsâ⬠each year and is ââ¬Å"considered the single most serious cause of blindness amongst childrenâ⬠in the developing countries. ââ¬Å"A possible solution to this problem is the genetic modification of rice. â⬠( Potrykus, quoted inGenetic Modification) Although GM foods are benefical for the food value, in some circumstances, it can be very harmful for human health. Without too much control eating genetically modified food can be dangerous and it can lead lots of diseases like Eosonophil Myalgia Syndrome. In this debate, the Physicians and Scientists for Responsible Application of Science and Technology, is a website to educate the general public about genetic engineering in general and foods, revealed that After eating a food supplement produced by genetically engineered bacteria, ââ¬Å"37 persons were killed 1500 people were permanently disabledâ⬠in the US in a disease called Eosonophil Myalgia Syndrome. It was caused by one or more extremely poisonous substances that unexpectdedly appeared in this food supplement. This accident confirms the predictions of molecular biologists that genetic engineering can cause the appearance of dangerous unexpected substances. As a Conclusion, there are lots of arguments in the GMF. Maybe It can be a solution for lots of problems, maybe it can be invention of the this century. I think, however, without too much researching about GMF we cannot use it to gain profit. Because human health is important than anything. We have to more careful. In the future, After very deep research about the GMF, we can solve the sustanibility problem.

Concert Essay Example | Topics and Well Written Essays - 1000 words
Concert - Essay Example The band consists of 80 players, using instruments like First and Second Violin, Viola, Cello, Bass, Harp, Percussion, Timpani, Tuba, Bass, Trombone, Trumpet, Horn, Contrabassoon, Bassoon, Bass Clarinet, Clarinet, Cor Anglais, Oboe, Piccolo and Flute. French overture means opening and indicates the formation or introduction to a performance. An overture is normally in three parts (fast-slow-fast). The 1812 Overture was about the battles between Napoleon's French Army and the Russians. Within the piece, there is therefore the inclusion of anthems, gunfire and church bells. With a number of performers, who took up the upper deck and the lower space of the venue delivered an amazing performance which was met with not only appreciation, but also applause by the listeners. 5. The JOURNEY - The 1812 Overture is a classic that takes you through emotional up's and downs. Various instruments have been used to bring out this effect, a set of violins to bring out the lower and higher moods. Bass, bass clarinet, bassoon to depict drama and gunfire, trumpets to indicate rises and emotions, flute and piccolo to bring out calmness. The use of church bells to indicate the end. The overture follows a stereotypical format which is the fast-slow-fast and the composer has managed to show both the sides of the story, 2 marching armies whose troops were brimming with enthusiasm in defeating their enemy, thus motivated. The beginning of the clash between the 2 armies, the scenario of the war accompanied by gunshots, a drop in the music depicting a low mood or defeat and the end of a war signaled by the ringing of church bells. 6. Evaluation of the performers - The BBC National Orchestra of Wales is renowned for their performances with resident composer, Guto Puw delivering mind blowing original performances and pieces by other composers with immaculate brilliance. Grant Llewellyn, who is the music director of the North Carolina Symphony Orchestra and principal conductor of the Handel and Haydn Society is known for his exceptional charisma, energy and easy authority in music of all styles and periods. The performers who were 80 in number for this ensemble excluding the composers delivered an exceptional renderance of Tchaikovsky's 1812 overture deserving recognition and applause. 7. In-depth analysis of "one piece from the concert" For our analysis, we can choose the beginning of the composition. At approximately 4:00 minutes a drum roll comes on, and when

Fast protein liquid chromatography (FPLC) Term Paper
Fast protein liquid chromatography (FPLC) - Term Paper Example Furthermore, it supposes that the chromatographic column contains an infinite number of separate layers (theoretical plates). Separate equilibrations of the sample between the stationary and mobile phase occur in these layers. The analyte moves down the column by transfer of equilibrated mobile phase from one ââ¬Ëplateââ¬â¢ to the next. There is a more convincing theory, ââ¬Ëthe rate theory.ââ¬â¢ This theory depends on the speed of elution and thus speeds of diffusion of the dissolved particles. The analysis and application of this theory leads to the Van Deemter equation. This equation relates the variance per unit length of a separation column to the linear mobile phase velocity by considering several factors. They are physical, kinetic, and thermodynamic properties of a separation. The physical factors are such as; A) Eddy diffusion. B) Longitudinal diffusion C) Resistance to mass transfer It (chromatography) is thus seen to exploit the differences in partitioning beha vior between a mobile phase and a stationary phase to separate the components in a mixture. These components contained within a mixture may interact with the stationary phase based on charge, differing solubility or adsorption capability. Several terminologies are associated with the process of chromatography; a) The analyte- this is the substance to be separated during chromatography. b) Bonded phase- this is a stationary phase that is covalently bonded to the support particles or to the inside wall of the tube being utilized.. c) A chromatogram is the visual output of the chromatograph. d) The eluate is the mobile phase that is leaving the separation column. e) The eluent is the solvent that carries/dissolves the analyte. f) The immobilized phase is a stationary phase that is immobilized on the support particles, or on the inner wall of the column tubing. It is similar to the bonded phase g) The mobile phase is the phase that moves in a definite direction. h) Theà soluteà refe rs to the sample components in a solvent. i) Theà solventà refers to any substance capable of solubilizing another substance. This is important especially in the liquid mobile phase in liquid chromatography. Several methods of chromatography exist as well (singh). They include; 1) Chiral chromatography 2) Countercurrent chromatography 3) Pyrolysis gas chromatography 4) Simulated moving bed chromatography 5) Reversed phase chromatography 6) Two dimensional chromatography 7) Expanded bed adsorption chromatography 8) Size exclusion chromatography 9) Ion exchange chromatography 10) Supercritical fluid chromatography 11) FPLC The FPLC is the method of interest in this case. The FPLC method was developed and marketed in Sweden by the Pharmacia Company in 1982. It was originally called fast performance liquid chromatography. Principle of functioning The purpose of purifying proteins with FPLC is to deliver quantities of the target protein at sufficient purity. This is done in a way tha t ensures the protein is in a biologically active state to suit its further use. Furthermore this can mean pure enough that the biological activity of the target is retained. This high level of purity requires preliminary preparation of the sample. This is mostly by IEC. In most FPLC systems, there are two solvents/ buffers (A, B). There is also a resin that is chosen so that the protein of interest will bind to it by a charge interaction. When the sample and mix of buffer (100% A) and protein is introduced, the protein will bind to

Visionary Idealism Essay Example | Topics and Well Written Essays - 1250 words
Visionary Idealism - Essay Example For him, the process of artistic creation holds the potential of transcending the limitations of the mind and more fully expressing the divine spirit. He also believes that art can induce within the viewer an elevated state wherein spiritual states of being are attained (Grey). In this essay, I am going to cover a brief history of his life, the progression of his art and performances, where his art is displayed and has been used, and some positive and negative reviews of his works. My purpose is to critically critique Alex Grey's artistic style and vision. Alex Grey was born in Columbus, Ohio on November 29, 1953. Being the middle child of a middle-class couple, he strove to please his father by excelling in drawing. It was his father, who was a graphic designer, who saw in him his exceptional talent and encouraged his drawing ability. As a young child he would collect insects and dead animals from around the neighborhood and bury them in the back yard. From his earliest drawings to his performances, paintings and sculptures, the themes of death and transcendence have been woven throughout (Grey). During his teenage years he lived a solitary life in a world of his own imagination that could not be easily understood by others and did not give much concern to right or wrong. His art during that time shows how confused he was about himself, and about life and spirituality. It led him to express the tearing apart, the confusion, and the duality within his being. He attended the Columbus College of Art and Design for two years (1971-73), then dropped out and painted billboards in Ohio for a year (73-74) (Grey). He then attended the Boston Museum School for one year to study with the conceptual artist Jay Jaroslav (Grey). This is also where he met his wife Allyson, the artist. During this period he had a series of entheogenically induced mystical experiences that transformed his agnostic existentialism to a radical transcendentalism (Grey). He then spent five years at Harvard Medical School working in the Anatomy department studying the human body (Grey). As expected, the earlier works of Alex Grey (both drawing and painting) are simpler and more of self portrayal. His later works have shown maturity and complexity, moving out of self but still focusing on the human anatomy. What stuck out most about his early works is how talented and detailed his lines and features are, and how almost perfectly he has recreated himself in his visual arts. His later portrayal of himself reveals his own self realization and self actualization, revealing the inner struggles and duality of his inner being. He is able to show his audience what transpires within himself and the difficulties he has been going through as he is initiated into the growing complexity of his inner and outer world. In addition, his focus on the human eye in many of his works reveals an all-knowing existence of somebody, be it himself or God or any other important person in his life, which truly affects him and all of his life. One example is the "Vision Mission." The eye is placed above, which is believed as the vision, while the hand with the pointing finger below may stand for the mission. This drawing may have a spiritual implication and may have a much deeper meaning from what is actually shown. Moreover, his

Critique about putting a hyper child under medication to make them Assignment
Critique about putting a hyper child under medication to make them calm - Assignment Example Danielââ¬â¢s mother noticed that he was hyperactive when he became nine months old. Danielââ¬â¢s mother noted a connection between certain foods and Danielââ¬â¢s level of activity. At first, the doctors dismissed the connection between Danielââ¬â¢s hyperactivity. Regardless, Danielââ¬â¢s mother decided to conduct research and determine if diet contributes to hyperactivity. Currently, Daniel is a calm boy because his mother realized a diet that was suitable for him. Danielââ¬â¢s story is a testament that there is no need put a hyperactive child on medication to keep him or her calm. It is well known that medication always comes with side effects regardless of its purpose. It is wrong to put a young child on medication just because it is difficult to deal with his or her hyperactivity. The drugs do not even treat the hyperactivity. They are meant keep them calm for a specific period. Subjecting a child to medication for a natural condition only predisposes them to many dangers associated with the different drugs provided for hyperactivity. Danielââ¬â¢s success story is evidence that there are other ways to control hyperactivity children without having to put them through a lifetime of medication. In conclusion, no child deserves to be exposed to the potential side effects of the medication at a very tender age because of a natural condition. The dangers of getting used of drugs are much greater than the trouble that a hyperactive child creates. Therefore, parents should emulate what Danielââ¬â¢s mother did. She found alternative ways to help hyperactive children without

Australia Politics Essay Example | Topics and Well Written Essays - 1750 words
Australia Politics - Essay Example As a response to a process through which 'politics' itself is being redefined, cynicism has greater than before and the proportion of casual or swinging voters has augmented from around 5 per cent before 1972 to about 30 per cent in the premature 1990s (During, S. 2002, pp. 339-53). In other words, traditional allegiances and processes of political identification have been dissolving since the mid 1970s. The 'Australian Settlement' can be sight as embodying a political settlement, as well as financial and educational settlements. This political settlement took the form of the two-party system that came into being subsequent the fusion among the Free Traders and the Protectionists to generate a solitary liberal party in 1909. The fusion brought into being a simple Labor-non-Labor separation in Australian politics a split that was to characterise the nature of politics for the whole of the era of Modern Australia. Moreover, it was the 'Australian Settlement', which defined what politics was to be about in Modern Australia. As Ian Marsh has put it, the 'two party arrangement crystallised this pattern of politics and restricted the scope of government to the idea of Australia which was tacitly decided in the 1909 settlement'. It is worth recalling that at the time of the creation of the two-party system Australia possessed only limited cultural diversity. Most of the Australian population, except for a small elite, was educated to a primary level, which is not surprising given that the majority of them were employed in manual or semi-skilled occupations. The employment opportunities for women were equally restricted (Robert Murray, pp. 23). The politics created and definite by the two-party system reproduce the realities of Australian life, and the division among labour and capital was at the centre of that realism. It was likely for both parties to follow a national attention, as defined by the 'Australian Settlement', even as they differ over the precise form of that national interest (Fowler, H. and Wainwright, M. 2001, pp 337-339). Aim Our aim has been to show how literacy debates are fundamentally a contest of social visions and ideologies. The documentary history is about how community debates over literacy and teaching have been used to endorse dissimilar versions of suitable behaviour, and dissimilar visions of the ideal literate student and inhabitant. It effort For a succinct Australian account of this compass reading to past work, see Tyler and Johnson (1991). to explain the varied and rival images of the literate and uneducated, and of the causes and penalty of literacy and illiteracy, and offer an account of how and why literacy' came to matter in Australian educational and political Life. We will now talk about some of the insinuation and findings from the research, and propose how it continues to notify our labor on literacy formations and instructive politics. Scope No doubt, Australia's place in global trade turn out to be more shaky in the last quarter of the twentieth century. By the 1980s Australia was considerably less spirited in world terms, not capable to sell abroad goods and services in the quantities and at the prices wanted to sustain customary prosperity. Australia's exports grow year by year but not as fast or as gainfully as those of many additional countries, and its share of earth trade fell between 1953 and

The intent is to inspire an appreciation for nursing research and to show how it can improve nursing practice and how results can be translated into health policy. Nursing research is de? ned as a systematic approach used to examine phenomena important to nursing and nurses. A summary of major points in the evolution of nursing research in relation to contemporary nursing is presented. A description of private and public organizations that fund research is given, and their research priorities are listed. Major research designs are brie? y described, and examples of each are given. Nurses of all educational levels are encouraged to participate in and promote nursing research at varying degrees. The process of locating research and evidence for practice is reviewed. Students are introduced to the research process and guided in the process of critically appraising published research and research syntheses. Ethical issues related to research are examined, and historical examples of unethical research are given. The functions of the institutional review board (IRB) and the use of informed consent in protecting the rights of human subjects are emphasized. DEFINITION OF NURSING RESEARCH Research is a process of systematic inquiry or study to build knowledge in a discipline. The purpose of research is to develop an empirical body of knowledge for a discipline or profession. Speci? cally, research validates and re? nes existing knowledge and develops new knowledge (Burns and Grove, 2007). The results of research process provide a foundation on which practice decisions and behaviors are laid. Research results create a strong scienti? c base for nursing practice, especially when deliberately and carefully evaluated for application to speci? c clinical topics (Melnyk and Fineout-Overholt, 2005). In recent decades the nursing discipline has begun to pay much greater attention to the necessity of participating in research. Nursing research is a systematic approach used to examine phenomena important to nursing and nurses. Because nursing is a practice profession, it is important that clinical practice be based on scienti? c knowledge. Evidence generated by nursing research provides support for the quality and cost-effectiveness of nursing interventions. Thus recipients of health careââ¬âand particularly nursing careââ¬âreap bene? ts when nurses attend to research evidence and introduce change based on that evidence into nursing practice. The introduction of evidence-based change into the direct provision of nursing care may occur at the individual level of a particular nurse or at varied organizational or social levels. In addition to nursing research aimed at affecting the direct provision of nursing and health care to recipients of nursing care, nursing research also is needed to generate knowledge in areas that affect nursing care processes indirectly. Research within the realms of nursing education, nursing administration, health services, characteristics of nurses, and nursing roles provides evidence for effectively changing these supporting areas of nursing knowledge (Burns and Grove, 2007). Today the importance of nursing research to the discipline is recognized. However, much nursing history underlies the current state of acceptance. EVOLUTION OF NURSING RESEARCH Nursing research began with the work of Florence Nightingale during the Crimean War. After Florence Nightingaleââ¬â¢s work, the pattern that nursing research followed was closely related to the problems confronting nurses. For example, nursing education was the focus of most research studies between 1900 and 1940. As more nurses received their education Nursing Research and Evidence-Based Practice CHAPTER 6 107 in a university setting, studies regarding student characteristics and satisfactions were conducted. As more nurses pursued a college education, staf? ng patterns in hospitals changed because students were not as readily available as when more students were enrolled in hospitalaf? liated diploma programs. During this period, researchers became interested in studying nurses. Questions such as what type of person enters nursing and how are nurses perceived by other groups guided research investigations. Teaching, administration, and curriculum were studies that dominated nursing research until the 1970s. By the 1970s more doctorally prepared nurses were conducting research, and there was a shift to studies that focused on the improvement of patient care. The 1980s brought nursing research to a new stage of development. There were many more quali? ed nurse researchers than ever, widespread availability of computers for collection and analysis of data, and a realization that research is a vital part of professional nursing (Polit and Beck, 2006). Nurse researchers began conducting studies based on the naturalistic paradigm. These studies were qualitative rather than quantitative. In addition, instead of conducting many small, unrelated research studies, teams of researchers, often interdisciplinary, began conducting programs of research to build bodies of knowledge related to speci? c topics, such as urinary incontinence, decubitus ulcers, pain, and quality of life. The 1990s brought increasing concern about health care reform, and now in the twenty-? rst century, research studies focus on important health care delivery issues, such as cost, quality, and access. Research ? ndings are being used increasingly as the basis for clinical decisions. Evidencebased practice (EBP) can be de? ned as the process of systematically ? nding, appraising, and using research ? ndings as a basis for making decisions about patient care. The rise of technology and the worldwide access and ? ow of information have transformed the decision-making processes of practitioners.

Nurses and other health care professionals are more likely to look for solutions, choices, and outcomes for patients that represent the best available knowledge internationally (Hamer and Collinson, 2005). RESEARCH PRIORITIES Why set priorities for research in the nursing discipline? Can nurses do research in areas that match personal areas of interest? The answer to the second question is, yes, certainly. But nursing exists to provide high-quality nursing care to individuals in need of health-promoting, health-sustaining, and health-restoring strategies. The main outcome of research activity for a nurse is to eventually put the knowledge gained to work in health care delivery. Research priorities, often set by groups that fund research, encourage nurse researchers to invest effort and money into those areas of research likely to generate the most bene? t to recipients of care. Of course the funding opportunities offered by such groups do not hurt the research enterprise either. Research costs money. Thus nurses engaged in research often match personal interests with funding opportunities that are available during the planning phase for a proposed investigation. Two major sources of funding for nursing research are the National Institute of Nursing Research (NINR) and the Agency for Healthcare Research and Quality (AHRQ) (formerly known as the Agency for Health Care Policy and Research [AHCPR] and reauthorized as AHRQ by Congress in 1999). Both of these organizations are funded by federal congressional appropriations. Private foundations and nursing organizations also provide funding for nursing research. National Institute of Nursing Research As part of the National Institutes of Health (NIH), the NINR supports research on the biologic and behavioral aspects of critical health problems that confront the nation. The NINRââ¬â¢s research focus encompasses ââ¬Å"health promotion and disease prevention, quality of life, health disparities, and end-of-lifeâ⬠(NINR Strategic Plan 2006-2010, 2006). A small sampling of potentially supported research topics includes those aimed at: ? Determining disease risk and treatment through utilizing genetic information ? Determining effective health-promotion strategies for individuals, families, and communities ? Discovering approaches that encourage people to effectively take responsibility for symptom management and health promotion ? Assisting in identi? cation and effective management of symptoms related to acute and chronic disease ? Improving clinical settings in which care is provided ? Improving the quality of care giving in settings such as long-term care facilities, the home, and the community ? Understanding predisposition to disease, socioeconomic factors that in? uence health, and cultural health practices that either protect from or expose to risk for health problems ? Improving symptom management for those at end of life The areas of research emphasis published by the NINR are useful guides for investigators developing proposals but are not considered to be prescriptive in nature. Investigators bring to bear their own unique expertise and creativity when proposing research in harmony with NINR priority research areas. Annually the NINR conducts a roundtable discussion with multiple nursing organizations to obtain the feedback of the disciplines regarding the need for continued or new research Nursing Research and Evidence-Based Practice CHAPTER 6 109 emphases. Information obtained is used in setting future research agendas and making decisions about funding of proposals submitted by researchers (Of? ce of Science Policy and Public Liaison, NINR, 2009). The NINR website details current announcements regarding research priorities (www. ninr. nih. gov/ResearchAndFunding). Agency for Healthcare Research and Quality The AHRQ broadly de? nes its mission as ââ¬Å"improving the quality, safety, ef? ciency, and effectiveness of health care for all Americansâ⬠(AHRQ, 2009a). As an agency of the U. S. Department of Health and Human Services, the AHRQââ¬â¢s health-related aims are to reduce the risk of harm by promoting delivery of the best possible health care, improve health care outcomes by encouraging the use of evidence to make informed health care decisions, transform research into practice to facilitate wider access to effective health care services, and reduce unnecessary costs (AHRQ, 2009a). Since the inception of the agency in 1989, strategic goals have centered on supporting improvements in health outcomes, strengthening measurement of health care quality indicators, and fostering access to and cost-effectiveness of health care. The 1999 reauthorizing legislation expanded the role of the agency by directing the AHRQ to: ? Improve the quality of health care through scienti? c inquiry, dissemination of ? ndings, and facilitation of public access to information. ? Promote patient safety and reduce medical errors through scienti? c inquiry, building partnerships with health care providers, and establishment of centers for education and research on therapeutics (CERTs). ? Advance the use of information technology for coordinating patient care and conducting quality and outcomes research. ? Establish an of? ce on priority populations to ensure that the needs of low-income groups, minorities, women, children, the elderly, and individuals with special health care needs are addressed by the agencyââ¬â¢s research efforts. The research-related activities of the AHRQ are quite varied, but a recent shift emphasizes a more deliberate translation of research evidence into practice. In a process similar to that used by the NIH, investigators are invited to submit research proposals for possible funding through grant announcements. A listing of current areas of the agencyââ¬â¢s research interests can be found online at www. ahrq. gov/fund/portfolio. htm. The AHRQ actively promotes EBP, partially through the establishment of 14 EBP centers (EPCs) in the United States and Canada. EPCs conduct research on assigned clinical care topics and generate reports on the effectiveness of health care methodologies. Health care providers may then use the evidence in developing site-speci? c guidelines that direct clinical practice. AHRQ also actively maintains the National Guideline Clearinghouse (www. guidelines. gov), an website that makes available to health care professionals a wide array of clinical practice guidelines that may be considered in health care decision making. Another recent addition to AHRQââ¬â¢s initiatives is the Healthcare Innovations Exchange (2009b), which provides a public source of information about innovations taking place in health care delivery. Submitted innovations are reviewed for the quality of achieved outcomes, providing evidence as a foundation for decision making by others who may be searching for or considering similar innovations. Although most AHRQ activities are intended to support health care professionals and institutions, the agency supports health care recipients by designing some information speci? cally for dissemination to the lay public (AHRQ, 2009a). 110 UNIT ONE The Development of Nursing Private Foundations Federal funding is available through the NIH and the AHRQ. However, because obtaining money for research is becoming increasingly competitive, voluntary foundations and private and community-based organizations should be investigated as possible funding sources. Many foundations and corporate direct-giving programs are interested in funding health care projects and research. Computer databases and guides to funding are available in local libraries. In addition, grant-seeking enterprises often purchase subscriptions that allow computer access to enhanced listings of funding foundations that include information about the types of projects those foundations typically fund. Though subscriptions are expensive, costs are often balanced by the ef? ciency with which suitable funding prospects are identi? ed. An example of such a service is Prospect Research Online (www. iwave. com). Private foundations, such as the Robert Wood Johnson Foundation (2009a, 2009b) or the W. K. Kellogg Foundation (2009), offer program funding for health-related research. Investigators should be encouraged to pursue funding for small projects through local sources or private foundations until a track record is established in research design and implementation. After several years of experience in the research arena, investigators are more likely to be successful in securing funding through federal sources, such as the NIH. Nursing Organizations Sigma Theta Tau International (STTI), the American Nurses Association (ANA), and the Oncology Nurses Society (ONS), are a few of the nursing organizations that fund research studies. STTI makes research grant awards to increase scienti? c knowledge related to nursing practice. STTI supports creative interdisciplinary research and places importance on identifying ââ¬Å"best practicesâ⬠and benchmark innovations. Awards are made at the international and local chapter levels. The ANA awards small grants through the American Nurses Foundation. Specialty nursing organizations offer grants to support research related to their specialty. For example, the ONS awards grants that focus on issues related to oncology. To summarize, multiple potential sources of funding are available for research projects. The individual or group wishing to conduct research will need to carefully develop a proposal, search for a possible funding source, and submit the proposal. Libraries and the Internet provide ample information about the many foundations and organizations interested in funding research endeavors. Most research institutions establish of? ces that help in the search and procurement of funding. Thus researchers are supported in their work of knowledge building. COMPONENTS OF THE RESEARCH PROCESS The research process involves conceptualizing a research study, planning and implementing that study, and communicating the ? ndings. The process involves a logical ? ow as each step builds on the previous steps. These steps should be included in published research reports so that the reader has a basis for understanding and critiquing the study (Box 6-2). STUDY DESIGNS Study designs are plans that tell a researcher how data are to be collected, from whom data are to be collected, and how data will be analyzed to answer speci? c research questions. Research studies are classi? ed into two basic methods: quantitative and qualitative, two distinctly different approaches to conducting research. The researcher chooses the method based on the research question and the current level of knowledge about the phenomena and the problem to be studied. Quantitative research is a formal, objective, systematic process in which numeric
