A basic science of public health Essay Example for Free

A basic science of public health Essay According to Friis, epidemiology has to do with the distribution and determinants of health and diseases, morbidity, injuries, disability, and mortality in populations. It is considered a basic science of public health, because its studies are applied to the control of the various health problems in the population. Also, its methods are applied to various health-related fields such as health care administration and health education. Because its focus is on the amount of health and disease in the population, it is at times referred to as population medicine. There are various uses and applications of epidemiology. Some specific applications of epidemiology that Friis did not specifically mention in lesson 1are genetic epidemiology, environmental epidemiology, and occupational epidemiology. Genetic epidemiology puts an emphasis on hereditary factors that may play a role in various human diseases in families and in populations. Research in this area is focused on the risk factors and traits of the genetic basis of diseases. Members of a Psychiatry department in Virginia completed a meta-analysis on the genetic epidemiology of major depression using relevant data from previous primary studies. They concluded that major depression is as a result of genetic influence, not alone, but along with environmental influence. This conclusion was made on the basis of a review of family, adoption, and twin studies that met specific criteria for the primary studies. Environmental epidemiology studies the environmental exposures that are related to various diseases, illnesses, developmental conditions, disabilities, and deaths in populations. Some examples of these environmental exposures are air pollution, radiation through air, water, or food contamination, second-hand smoke, and hazardous waste. Health conditions such as cancer, cardiovascular disease, and reproductive problems are some of the effects of these environmental exposures. A local example of this is the pollution from the refineries here in Corpus Christi. People who reside near the refineries have a 17% higher cancer rate than the rest of the city. There are apparently many consistently sick residents in the area. They are called the ‘Black Thumb’ neighborhood, because the soil in the area is poisoned and contaminated by the pollu tion from the refineries. The application of epidemiologic methods to populations of workers is occupational epidemiology. Studies on this topic involve various work-related patterns of disease and illness. They look at workers exposed to various risk factors such as heavy metals or chemicals and determine if these exposures result in adverse health outcomes. There is also a focus on biological and physical health effects as well. Occupational Epidemiologists attempt to study how often workers are injured on the job, what groups are most affected, and the reasons for these injuries. The results from these studies are used to find ways to prevent or reduce the risks of injuries and illnesses on the job. In conclusion, the various epidemiologic methods and studies are applied to the control of health problems in populations. Three specific applications of epidemiology are genetic epidemiology, environmental epidemiology, and occupational epidemiology. Genetic epidemiology is concerned with the role of genetic factors in determining health and disease in families and in populations. Environmental epidemiology is concerned with the relationship between exposures from the environment and adverse health outcomes in populations. Occupational epidemiology studies work-related patterns of disease and illnesses. The existence of these various epidemiologic applications help to identify and prevent the causes of health and disease in our communities. Epidemiology provides us with necessary and beneficial information we need to live a healthy life. References Corpus Christi’s Refinery Row. (n.d.).

The Shifting of Pangea :: essays research papers

The Shifting of Pangea Have you ever noticed that a map of the world looks like a puzzle and the continents look like the pieces that would fit together to complete the puzzle.   Ã‚  Ã‚  Ã‚  Ã‚  In 1912, Alfred Wegener, a German scientist and an adventurer, came up with a theory that the continents had once been part of a â€Å"supercontinent†. Wegener proposed that, over 200 million years, what he called Pangea had separated and became individual pieces. Pangea means â€Å"all lands† in Greek, and that is what Pangea was, a very large landmass when all of the continents were connected. When Wegener first proposed this idea in 1912, people did not buy into this theory. One of the problems that Wegener faced was that he believed that the continents had drifted apart, but he couldn’t explain how they had drifted apart. Another problem was that there was a theory already in place called the â€Å"Contraction Theory†. This theory stated that the Earth was once a molten ball and in the process of cooling, the surface cracked and folded up on itself. One of the problems with this theory was that it suggests that all mountain ranges w ere the same age, and this could not be true. Wegner’s explanation was that continents shifted and these shifting plates would collide, encounter resistance from one another, compress, then fold upwards to form mountains near the edges of the plates.   Ã‚  Ã‚  Ã‚  Ã‚  Eons ago India and an ancient ocean called the Tethys Ocean sat on a tectonic plate. This place was shifting northward towards Asia at a rate of 10 centimeters per year. The ocean got progressively smaller unit about 55 million years ago when it collided with Asia. There was no more ocean left of lubricate the subduction and so the plates formed the High Plateau of Tibet and the Himalayan Mountains.   Ã‚  Ã‚  Ã‚  Ã‚  Evidence that Pangea may have existed can be found in land animals, vegetation, mountains, and the climate. Fossils and plants that are the same, can be found on different continents, across oceans. Assuming that the land was once connected, animals could have walked across the large land mass and not have to swim. For example, the mesosauras (a land animal) could not have traveled from South America to Africa because of the Atlantic Ocean. Yet, there are fossils of this animal on both continents. Another example is there are trees in South America, Africa, India, Australia, and Antarctica that are of the same origin.

My Decision to Enroll in College Essay

People have different reasons and point of views why it is important for them to enroll in college. Basically, achieving a degree is a stepping stone to reach one’s goals. For me, I enroll in college, definitely, because it is a given fact and expectation that after high school, I need to choose a course and to enroll in an institution where I want to obtain my degree. First, I figure out what I want, what I really want to do in life. Whatever my decision is, it is anchored to what I yearn to do and to achieve in life. Definitely, I do study hard in order for me to achieve high grades and to have flying colors during graduation. I want to satisfy my parents’ expectations on me so I certainly do my best in every subject. I make sure that I devote my time equally; however, it is not always applicable in my schedule because there are times when I find it arduous to understand some of the topics in some of my subjects so I give more time on the difficult ones. I believe that learning is an on-going process. The strategies of my professors in presenting the lessons each day have a great impact on me. Whatever the technique is, it may be visual aids like movies, slide shows, etc, it definitely helps me in comprehending the lessons very well. Professors, indeed, affect my moods and enthusiasm. I like creative and unconventional professors. The professors and their teaching techniques and strategies contribute to my enthusiasm and motivation to do very well in class. Nevertheless, if I do not like the professor due to his/her temperament and conventional ways of teaching, I still do my best to grasp every learning and knowledge that s/he bestows. Because there are a lot of ways to learn, I believe that it is not just confined to the four-corner rooms of the university. Outside or extracurricular activities such as fieldtrips, research or case study competitions, internships or on-the-job trainings will definitely help me realize my potentials and will definitely aid me to reach for my goal. Gaining experiences outside school’s four-corner rooms enable me to be more confident, more competitive and more competent. I have been brought up by my parents in an authoritative way. They are neither over-protective nor over-domineering. They make me speak and explain my side every time I commit a mistake; in return, they do listen and reprimand me accordingly. For me, they are the best paragons. Because of that, I yearn to do the same for my children. I will not be the authoritarian parent just like some of my friends’ and classmates’ parents. If it is already time for them to enroll in college, I will just let them choose what course they want to take. I will not intervene with what they want because definitely, intervention to a person’s likes and wants affect his/her enthusiasm to perform well. The drive and the motivation to reach for their goals will, indeed, slow down. Advices, motivations and anecdotes from my experiences in college will help my children in challenging them to excel higher. If I have made it, I believe that they, too, can. From the very start, I will condition them to manage their time properly but not intervening too much to what they really want to do because I might suffocate them. They will just probably yearn to be a bird, not the droopy one†¦ but the free bird that spreads its wings and soars high. Enrolling in college and obtaining a degree are the stepping stones to have a good future, a stable job and a career. It helps people in realizing their goals and visions in life. My current career and our status in life is the best evident that I can show them with regards to the benefits of pursuing a degree in college. They need not be bums or dependents for the rest of their lives. Graduating in college allows a person to stand on their own feet. Whatever course they want to take, it is important for them to know that it is a competitive world out there. If someone yearns to have a high paying job, s/he must choose the in-demand courses like those under Technology, Business, etc. Each one must be acquainted with marketing strategies such as knowing the appropriate advertisements. Or being aware of the latest technology, which is now evolving to be wireless.

How to Sing Happy Birthday in Chinese

The Happy Birthday Song has a strangely contested history. The tune was originally composed in the late 1800s by Patty and Mildred Hill, though the lyrics were not the same. In fact, the Hill sisters titled the song Good Morning To All. Somewhere along the way, the phrase happy birthday became associated with the melody. In 1935, the Summy Company registered a copyright for the Birthday Song. In 1988, Warner Music bought that copyright and has been making big bank ever since. Warner Music charged royalties for public performances of the Happy Birthday Song and appearances in film soundtracks. Only until 2016 did the popular song become public domain. In February 2016, a US federal judge closed a case ruling that Warner Music does not hold a valid copyright to the Happy Birthday Songs lyrics and melody. Now, the Birthday Song finally belongs to the public and is considered one of the most popular songs in the world. It has been translated into many languages, including Mandarin Chinese. Its an easy song to learn in Chinese since it is essentially just two phrases repeated over and over again.   Practice speaking the words to this song before singing them. This will ensure that you are learning the words with the proper tones. When singing in Mandarin Chinese, sometimes the tones are not clear given the melody of the song.
