Introduction Autism Spectrum Disorders (ASD’s) are disabilities that affect social and communication skills, and cause behavioural changes (CDC, 2012). There are three types of ASD’s; Asperger Syndrome, Pervasive Developmental Disorder, and Autistic disorder (autism). Autistic disorder will be the focus of this study (CDC, 2012). Children develop autism before the age of three years and struggle with it throughout their lives (CDC, 2012). “Autism creates many challenges in the child’s life and it negatively impacts; intellectual disabilities, language delays, social and communication difficulties and unexpected behaviour and interests” (CDC, 2012). Autism does not segregate between racial and ethnic groups, nor does it relate to socioeconomic status; however it has been proven to occur more often in males than in females (CDC, 2012). Over the past decade there has been a significant increase in the number of autistic diagnoses (CDC, 2012). Evidence has shown that the development of autism occurs during the pregnancy phase (Schmidt, 2011); which leads this study to analyze the association between intake of iron, and zinc during pregnancy and preventing autism in the offspring.
Specific Aims
The proposed study will be focused on whether women who take iron and zinc supplements during the three trimesters of the pregnancy will reduce the risk of autism in their offspring. The goal of this study is to develop an association between vitamin exposures and the outcome of prevented risk of autism. The proposal can potentially establish correlations that will help identify, and prevent risk factors of autism. Two objectives for this study are: to measure the prevalence of autism among young children in Canada, and to compare the levels of exposure and disease among three different cities in Canada.
Background:
There have been different studies conducted to explore the…...

...RUNNING HEAD: Descriptive Research Questions Shekubah Kamara 15 February 2013 RES 500 Research Methods for the Health Science Module 1 Trident University Newton, Bower, and Williams (2004) outline the process of “devising and revising” a research question, be it descriptive, relational, or comparative. After reading their paper, write a three-page paper that addresses the following: How do descriptive research questions differ from questions of relationship? From questions of comparison? When pursuing a descriptive research questions, what is being measure is aimed to describe the variables you are measuring. When the use of the word describe is used, simply means that these research questions are focused to quantify variables. To recognize a descriptive of to use these question you will often use questions that start with words such as "How much?", "How often?", "What percentage?", and "What proportion?” but also sometimes questions starting "What is?" and "What are?". Descriptive research questions focus on only one variable and one group, but they can include multiple variables and groups. In comparison to questions of relationship or comparison it is also common when using descriptive research questions to measure percentages and proportions. However, if you are using an experimental or quasi-experimental research design, or a more involved relationship-based research design, you are more likely to use just one or two descriptive research questions as a......

...Williams HRET Focus Areas As a health care professional, it is the responsibility of management to make the necessary steps to measure performance and ensure that quality care is given to all patients. For the purpose of this paper, I believe Quality and safety, and community health is important to all heath care administrators. Quality and Safety When one is considered to be an employer, it is the responsibility of the individual or individuals to protect their employees from safety hazards and promote optimal health. Health and safety laws have been passed to ensure the safety of workers and protect them from hazards in the workplace. (OSHA, 2012)The Occupational Safety and Health Act mandate and require employers to provide a workplace that is free of hazards and to cooperate with occupational safety and health standards. The Occupational Safety and Health Administration were created by Congress to enforce specific standards and to provide information on safety and health, training and assistance to employers and workers. (OSHA, 2012) OSHA enables workers to understand and clarify their right. If a problem is present, it is up to the employee to take proper precaution and notify the organization so that corrections can take place. As an employer, it is important to act promptly so that the matter is handled promptly and efficiently. There are many ways an individual can report an unhealthy work environment. It is imperative to research and document ways to......

...DO YOU CHOOSE A GOOD RESEARCH TOPIC? GIVE 5 EXAMPLES OF A GOOD RESEARCH TOPIC AND JUSTIFY WHY YOU CHOOSE THEM, I.E. PROBLEM ISSUES IN EACH TOPIC AND WHY THEY MUST BE RESEARCHED UPON. (NOT LESS THAN 2000 WORDS). WHAT IS RESEARCH? Research has been defined by different people in different ways. At any point in time, depending on what an individual is doing in relation to a particular topic or subject area of study, there is the tendency that one may deem that activity as a form of research. Research therefore cuts across all facets of human endeavour; in the sciences, humanities, electronics etc. These diversities create room for one to distinguish between what scientific research is and what a normal review of information is. “In the broadest sense of the word, the definition of research includes any gathering of data, information and facts for the advancement of knowledge”. MartynShuttleworth (2008). Research involves gathering of information and the examination of all the pieces of information gathered. The central goal of a good research is to come out with findings that add to the body of knowledge and available literature in that area of study. Martyn further explained that “reading a factual book of any sort is a kind of research. Surfing the internet or watching the news is also a type of research.” However, defining research this way tends to present a narrow view of research and does not convey in detail what scientific research is about. ......

...Evidence Based Practice. Research Methods. Evidence-Based Practice (EBP), the skill of using correct research methods, the importance of making informative decisions based on the best EBP within the health care industry as well as an example of EBP in regards to infection control and hand washing procedures will be key issues discussed throughout this essay. The health profession is continually developing and adapting in its implementation to health care techniques and skills due to changing world health conditions. It is therefore imperative that research be constantly conducted to analyse new research relating to health care to ensure health care practitioners are using techniques derived from the most current evidence (Aveyard & Sharpe, 2009). Evidence Based Practice can be defined as, “the conscientious, explicit and judicious use of current best evidence in making decisions about the health care of patients” (Sackett, Richardson, Rosenberg, & Haynes, as cited in Craig & Smyth 2007). The basis of EBP is that decisions are made by assessing not only the information at hand, but also integrating clinical experience, the most current evidence available, critical thinking and keeping in mind the patient’s best interest and preferences (Aveyard & Sharpe, 2009). Evidence based practice was developed because of the commitment of health care practitioners to social research and science (Mullen, as cited in......

As far as ‘research setting’ is concerned, the literature review discussed below threw up several mutual that were mentioned frequently in newspaper articles and magazines. I have chosen two, in two separate sectors (and in fact two different types of enterprise). I believe these are suited to this dissertation: The John Lewis Partnership, and The Co-operative Bank. I chose these two for a few reasons: • They are both well-known brands in their sectors (The John Lewis Partnership is involved mainly with food and non-food retail), and the Co-operative Bank, which is a personal banking institution within the Co-operative Group.

SANTIAGO In Partial Fulfillment of the Requirements for the Subject in Methods of Research Submitted by: Ana S. Transifiguracion Ria Marie M. Reyes Major in Technology and Livelihood Education Chapter I THE PROBLEM AND ITS BACKGROUND Introduction Nutrition is the result of the processes whereby the body takes in and uses food for growth, development and maintenance of health. Nutrition can also affect the body’s ability to resist disease, the length of one’s life and the state of one’s physical and mental well-being. Promoting good nutrition helps children grow, promotes human development and advances economic growth and eradication of poverty. Studies have shown that proper nutrition has a direct effect on student performance and behavior in school In many studies, cases of socioeconomic status seem to be an indicator of food insufficiency, which is simply the lack of available food to a household. Food insufficiency has been shown to directly affect children’s cognitive development. (Nutrition And Its Effects On Academic Performance How Can Our Schools Improve? By Amy Ross ) Poor nutrition on the other hand, is a chronic problem linked to poverty, poor nutrition understanding and practices, and deficient sanitation and food security. Lack of proper nutrition contributes to worse......

...What is research? Research in common parlance refers to a search for knowledge (Kothari, 2004) What is Knowledge? The Oxford Dictionary defines “Knowledge” as: * The information, understanding and skills that you gain through education and experience; * The state of knowing about a particular fact or situation; What other ways of knowing exist? “There are four ways of knowing” (Gakuu & Kidombo, 2014) Server time  Sensory Experience The Oxford Dictionary defines “Sensory” as “Connected to your physical senses” By this definition we can infer that we use our “Sensory Organs” to Know or Gain Knowledge. Our sensory organs include eyes, ears, nose, mouth and skin, We use our eyes to see things hence gaining knowledge; we use our ears to hear and gain knowledge…….etc. etc. We should not forget that this information or knowledge is first processed by our brain then and only then do we understand what it is we are seeing, hearing, tasting and so on and therefore understand. Normally we, see, hear, and smell taste touch. We gather a lot of data through our senses. “However, sensory knowledge is undependable and in some cases incomplete. The data we take through our sense do not account for all (or even most) of what we seem to feel is the range of human knowing. For us to obtain reliable knowledge, therefore, we cannot rely on our senses alone, but must check what we think we know with other sources” (Gakuu & Kidombo, 2014) The opinion of other is...

Discuss key issues and concerns arising from the fact that you, the manager, are also the researcher. Key issues and concerns 1. The key issues and concerns relating to any research project such as to estimate the sales potential in the domestic market, first points to the issue of defining the purpose of the research, the area sales manager or researcher must distinguish between symptoms of organizations problem regarding the manufacturing and marketing of the outboard engines, the manager’s perception of the problem, and the research problem (Cooper, & Schindler, 2011, p. 13). Conner (1997) also posited the importance of building market research plan by starting the process with a clear statement of the decisions one have to make.(Conner, 1997, p. H15) The purpose of the research should be clearly stated followed by the research process detail. 2. Figuring out the research process detail, the researcher or the manager should provide complete research proposal (Cooper, & Schindler, 2011, p. 13). 3.

...Psychological Factors Heather Mingee Research Methods Week 10 Assignment 2 Instructor Joseph Davis Psychological Factors The scientific method is an organized way of figuring something out and normally includes six parts (Galgas, 2014). The first step is to state my purpose. For example, for this assignment, my purpose would be to examine the psychological factors affecting how teenagers in an impoverished urban area spend their time outside of school. Second is my research. For my assignment, I would find out as much information on the area as possible. For example, I would talk to teachers to see what kind of after school programs are available and I would talk to the community to find out what kind of community programs are offered for the children. Third, after I do my research, I would develop a hypothesis. My hypothesis would be that since there are not many programs available to the children and they have a lot of free time, they tend to get in more legal trouble. The fourth step is to conduct my experiment. I would develop a questionnaire for the students on how they spend their free time outside of school. I would also develop a questionnaire for the teachers on new programs that they would like to see implemented. Fifth, I would analyze how having too much free time can have a negative impact on psychological effects. Sixth, I would conclude my research by checking to see if my hypothesis was correct. Using a questionnaire can cause errors because students......

...+ Research Methods Name: Institution: Research Process In any research endeavor, developing the research question is an important phase in the research process. It helps in the determination of the where, what, how and when of data collection. A well-developed question helps in focusing ideas and ensuring the collection of appropriate data. This case study examines various aspects associated with the research process. There are remarkable difference, descriptive and relationship questions. Newton, Bower & Williams (2004) contend that descriptive research explains the data and the characteristics under investigation by addressing questions of when, who, what, why, and where. It holds factual information, but does not determine the casual relationship between the information. On the other hand, relationship questions make use of the information or data provided and explains how a particular set of information can affect another set, and as a result determines the relationship between them (Blazer, 2007). Comparison research questions are used in describing cause and effect by asking why one aspect may have led to another. For example, “has mental illness among adults increased in the past decade?” is a descriptive question that makes use of raw data from one year to another to demonstrate that either an increase has or has not occurred over the past decade. A relationship question may attempt to determine the reasons why......

... we have to go through reasoning and research. Qualitative research in a complex analysis and is characterized by mathematical calculations but no experimentally. Quantitative research however is carried out experimentally and relies and builds on mathematical techniques such as quality, frequency and amount etc. Qualitative analysis provides more details and is more focused and deep process. Qualitative analysis put emphasis on how and what meaning is given to a certain situation.  Qualitative approach is subjective and has understanding nature. In this type of research, the researcher has to engage more with the subject under consideration. This type of research is also referred to as interpretative research, understanding and gathering information and interpreting it with respect to daily life. Quantitative research method involves the mathematical parameters such as height, weight and other parameters which have numerical value. The emphasis of this type of research is on the comparison between different variable of the system.   So it depends on mathematical techniques and procedures such as mean, median, frequency and other statistical procedures. According to Kotler et al “Marketing research is a process that identifies and defines marketing opportunities and problems, monitors and evaluates marketing actions and performance, and communicates the findings and implications to managements.”   This means that marketing research is the collection, evaluation and......

...Research Article The nurses'experience of possible HIV infection after injury and/or exposure on duty L Roets, Ph.D School of Nursing, Faculty of Health Sciences, University of the Free State LEZiady,M.Soc.Sc School of Nursing, Faculty of Health Sciences, University of the Free State. Keywords: Nurse, experience, HIV, infection, injury, exposure. Abstract: Curationis 31 (4): 13-23 The purpose of the research was to describe the experience of nurses in the studied hospital who had been exposed to possible HIV infection during injury or exposure on duty. A qualitative phenomenological descriptive study was used to describe the emotions and non-verbal reactions of the twelve participants during two subsequent in-depth interviews. These were conducted post-exposure, and after counselling and prophylactic treatment took place. The nursing staffs from a selected private hospital Were included in the study after exposure of blood and/or human body fluid. After completion of the study, it was found that the exposed staff's experience had two main categories. Firstly, they were grieving for the loss of the concept of being healthy and invincible, blessed with nursing sldlls and definite goals in life. The bereavement process included phases of denial, anger, anxiety and fear, with recurring thoughts regarding the adverse events, as well as acceptance which developed with time. The bereavement process and shock of the exposure had wider consequences to the family, as......
