Migraine Headaches: Probable Causes and Effective Treatments :: Biology Essays Research Papers

Migraine Headaches: Probable Causes and Effective Treatments During my first year of High School, I began getting frequent headaches, about three or four each week, which included symptoms of nausea, increased sensitivity to light and an intense throbbing pain localized to one side of my head. Immediately, my parents and friends noticed a change in my behavior. Shortly after the onset of these headaches, my academic performance suffered as the intense symptoms became debilitating. With their enduring persistence, I visited a neurologist who diagnosed me as suffering from migraine headaches. The symptoms were clearly indicative of classic migraines, which the neurologist informed me were usually genetic. Therefore, upon questioning me about my family history of neurological disorders, he did not find it surprising that my maternal grandmother had been plagued with severe headaches since her early twenties. Later, he explained to me that the precise cause of migraines was yet unknown but that there were some very effective treatments available t hat would prevent the onset of the migraines. After trying several different medications, we found a successful preventative drug, called Norpramine. Six years later, still on the medication, I only suffer from an intense migraine about two or three times per month. However, searching for the correct medication was the most painful and helpless process of my life, an experience that I would never care to relive. Before I had settled on Norpramine, I was using medications that were only effective in relieving the symptoms after the onset of a headache, one of which was a painful injection that had a variety of uncomfortable side effects. Over the years, I have done some superficial research on migraines, finding it perplexing that a disorder that affects millions of individuals is so difficult for scientists to pinpoint. Thus, I decided to focus this paper on the probable causes of migraine headaches and examine some of the possible treatments that work well for many individuals, including me. Migraine headaches affect an estimated 11 to 23 million Americans, women more commonly than men, and include symptoms like throbbing or pulsating pain and nausea (1). The first documented records of migraines originate from 3,000 B.C, when a popular treatment involved drilling holes in the skull to release evil spirits (1). Several scientifically based theories about the cause of migraines have recently developed, although the exact mechanism is still unknown. One of the current, highly supported theories suggests that migraines occur when there is a specific chemical imbalance in the brain, which in turn results in changes in the blood vessels (2).

The History of Harlem - Cultural Epicenter of America’s Black community

Over a significant time frame, African Americans have been forced to endure numerous hardships – one of which being the negatives stigmas that unfairly generalize their people, culture and way of life. Therese stereotypes of a whole nationality label Blacks as, â€Å"superstitious, lazy, ignorant, dirty, unreliable, (and even) criminal,† (â€Å"Stereotypes†). Such generalizations are products of the public’s perception, which has been diluted by rooted historic and current prejudice as well as the media’s conveyance of a well-known African American cultural center: Harlem. Despite negative connotations associated with it, Harlem stands as a community that strives to flourish and maintain its strong cultural status. George Canada, the founder of the Harlem Children’s Zone, states, â€Å"People think kids are all violent, and they’re all out fighting and shooting. Most of our children want to grow up in a peaceful community where they c an live their lives and become successful adults† (â€Å"Your City†). Because this area has been subject to consistent historic change, its past is rocky, which accurately mirrors the struggle of the African American people. In order to achieve a better understanding of both the African American community and its cultural hub, it is essential to know the area’s unique cultural history. From Renaissance to riots; drugs wars, violence and poverty, Harlem’s history as the cultural epicenter of America’s Black community may shed some light on the evolution of its current culture, people and stereotypes. In the 1920s, Harlem, New York had reached a cultural peak; â€Å"it became the most famous and influential black American ghetto† (Weisbrot). With the migration of African Americans to the north, Harlem became heavily concentr... ...l P. "Chapter 9: Harlem Renaissance - A Brief Introduction."

Null hypothesis. Marketing Essay

Assessment activity 1 1. When conducting research on behalf of your organisation or for a client organisation, how will you determine the most appropriate data sources to use? In this case the most suitable data source will be a desk research because this information will have already been gathered, analysed and reported on by other companies. It means that you will not waste time and money doing what others before you have done. 2. Why are cross checks and cross references necessary? To ensure the information is correct. Assessment activity 2 1. What tools would you use to collect and collate data and why would you use them? 2. Why should your desk research include the collection and analysis of data relative to the organisation’s current and past performance? Collection and analysis of data relative to the organisation’s current and past performance is very important to decide what we are looking for and the questions we are trying to answer. In this way our needs can be met. Assessment activity 3 Describe and explain the reporting formats that might be required to follow when submitting desk research results. Assessment activity 4 1. What is the difference between working and null hypothesis? A working hypothesis is a theory that we can use in our thinking about possible consequences. Such hypotheses allow us to predict and then look for results. Null hypothesis stands in direct contrast to its Alternative hypothesis. If we propose that action A will cause result B, we have a testable hypothesis, called the alternative. 2. How do these hypothesis help to focus the research? It help to guide the development of a research project and aid you in determining the direction you need to take and the questions to which you need answers. Assessment tool 2 1. What is desk research? Explain the steps involved Desk research is identification and analysis of information which has already been compiled and published in some form. The basics of a good desk research involve: – knowing where to look and what to look for – Understanding the quality of the source material – ensuring you get the right information. Core to any desk research is obtaining a list of sources. If you do know the subject area or the key jumping off points, you are likely to know exactly where to look immediately.

Specially in the case of coffee shops world. This report covers multiple and independent coffee shops. Coffee shops are defined as outlets where coffee accounts for a sizeable (usually at least around 40%) part of sales with quite a restricted, mainly packaged, food offer and small amounts if any, free alcohol. For some countries this will therefore include outlets such as donut shops and bars. Market value is based on expenditure including sales tax in these outlets; market volume is based on numbers of outlets. A Snapshot report is designed to provide instant preliminary market research. Each report provides an overview of the defined market, including market size, market forecast, segmentation, company market share along with top-line socio economic data. The data is supplied in both graphical and tabular format for ease of interpretation and analysis. There is is a mix of primary and secondary data sources. In addition each market contains an exclusive 5 year market size forecast. What’s more, our team of international research analysts are always on hand to provide further assistance where required. It’s a level of service you won’t find anywhere else. Secondary Research All secondary data sets in both local and global languages are derived from a range of sources, from government statistics to trade magazines. In addition, strong relationships with different companies. . Typically an analyst use a minimum of 3 to 4 data points for each table, analysing different aspects of the market. Full transparency of source data is provided for all secondary sources. Furthermore, we need to seek written permission from the original source which is quoted in every case, reinforcing the integrity and robust nature of the data. Primary Research – Trade Interviews Once secondary research has been exhausted, the language specialist researcher will then validate the information collected though semi-structured telephone interviews. Validation through telephone interviews is critical. We aim to receive confirmation from National Trade Associations, Statistic Offices, and major players of each quoted market. Forecast Methodology The basic model which the GMN forecast was built on is called the ISDE model, which is a framework based on four main concepts, namely: ï‚ · Interface ï‚ · Supply ï‚ · Demand ï‚ · Environment These four concepts can each affect the fluctuation of markets. First, all the main parameters are identified that affect the market/industry which is to be forecasted. Once identified the parameter is matched to and classified with the ISDE model. Interface These are factors which affect markets or industries. Mainly they regard to conditions and factors in the transition phase between the supply and demand. Supply  The total amount of goods and services that are available to purchase. Demand  Desire, ability or need by individuals or companies to purchase goods or services. Environment  The environment includes all factors external to the market or industry, which in one way or another, influence them. Each element of the ISDE model is affected by different parameters. Based on their understanding of the sector in question, the analyst selects the parameter regarded as the most relevant. For reasons of conformity, reliability and currency, the range of parameters at the analyst’s disposal is confined to eight parameters. These are updated on a monthly basis: ï‚ · Real agriculture ï‚ · Real industry ï‚ · Real manufacturing ï‚ · Real services ï‚ · Population ï‚ · Private Consumption The research methodology employed by MSI has been subject to numerous procedures to guarantee the quality and the reliability of the information contained within the reports. In-house consultants are employed full-time and receive a sixmonths training period to acquire and implement MSI’s research methodology. MSI’s methodology can be divided into five principal stages: †¢ Stage 1: secondary research  The consultancy teams work closely with trade associations, magazines, and government bodies operating in the researched field. Further research is also carried out from information available internally from our in-house documentation service and externally from the Internet. The latter is carried out by our teams which have the experience and the knowhow to efficiently and productively extract information from existing sources. †¢ Stage 2: primary research: interviews with trade sources The consultancy team proceeds to undertake a series of telephone or face-to-face interviews, with a representative selection of companies operating in the chosen industry. Every attempt is made to talk to leading players in the sector as well as smaller companies. Interviews are therefore carried out with manufacturers, distributors, importers, suppliers, installers and end-users. Indeed, some of our studies involve more than a hundred interviews. The data gathered from interviews is systematically checked and compared with the secondary research. †¢ Stage 3: analysis of the gathered data The information gathered during the two previous stages is then analysed and synthesized. A second series of interviews can be done if necessary to check and validate the data during this decisive stage. †¢ Stage 4: quantitative data MSI reports provide quantitative data, such as market estimates and forecasts, to measure the researched market. This data is based on the estimates obtained during stage 3. The quantitative data contained in the reports is based upon the consultancy teams’ appreciation and analysis of the market and is consequently unique to MSI. †¢ Stage 5: quality control  Each report is the subject of a rigorous checking and editing process by an experienced management team.

It is rather the labor practices related to the enforcement of labor laws which have been hampered to a great extent. This behavior of the countries can be directly seen as an attempt to attract higher Foreign Direct Investment (FDI). Similar findings were also made by Olney (2010) and he had observed that nations are engaged in a cutthroat competition with one another to reduce labor standards. For instance, the shifting of a vacuum cleaner plant of an American multinational company to Scotland had coincided with the relaxation of hiring standards in Britain. The case of Foxconn can also be treated as one which is blindly been driven by profit and neglecting labor standards. Foxconn which mainly provides electronic parts to big players like Apple have greatly reduced their labor costs after the recession and it was evident in the rising operating margin of the company. Research conducted by Chan (2013) had shown that the company have compromised basic human rights in a bid to meet the production quotas. This has led to suicide attempts among multiple employees. The supply chain of manufacturing companies in China, in an attempt to harness export, led growth have created working conditions which were so mechanical that it almost became impossible for the workers to survive.

Problems were not only present with Foxconn, but all multinational companies operating in China, which had minimum regard for labor standards. The problems do not lie solely with developing countries. Developed countries like the U. have also seen significant stagnation of real wages of workers engaged in the export-oriented industries as countries like China have very low minimum wages luring multinational companies to outsource their production processes in these countries (Becker, 2014).

Radiation Therapy As A Treatment For Cancer - 1173 Words

In 2007, it is predicted that almost 1.5 million people will be diagnosed with cancer in the United States (Pickle et al., 2007). More than half of these cancer patients will undergo the use of radiation as a means for treating cancer at some point during the course of their disease (Perez and Brady, 1998). Cancer, a disease caused by an uncontrollable growth of abnormal cells, affects millions of people around the world. Radiotherapy is one of the well known various methods used to treat cancer, where high powered rays are aimed directly at the tumor from the outside of the body as external radiation or an instrument is surgically placed inside the body producing a result of internal radiation. Radiation is delivered to the cancerous regions of the body to damage and destroy the cells in that area, terminating the rapid growth and division of the cells. Radiation therapy has been used by medicine as a treatment for cancer from the beginning of the twentieth century, with its earlie st beginnings coming from the discovery of x-rays in 1895 by Wilhelm Rà ¶ntgen. With the advancements in physics and computer programming, radiation had greatly evolved towards the end of the twentieth century and made the radiation treatment more effective.
