Prewriting Exercise Essay STEP 2) Describe two controversies surrounding this topic The first controversy is with regard to the idea of a universal health care system for the United States as a solution to its current health care situation of having an increasing rate of uninsurance among its working populace. While there is considerable current literature that argue that government should be able to provide adequate health care for all of its citizens, the questions of prioritization and proper allocation of funding comes into play. Specific research would have to be found to quantify as well as qualify the problem of uninsurance so as to evaluate just how much government action ought to be necessary. à à à à à à à à à à à The second controversy is whether or not current government action in terms of federal funding for Medicare and Medicaid is sufficient to address the needs of Americans. This issue examines what both of the programs currently provide and how much each has actually helped the American public in facing health service issues. Again, factual research need to be complied in order to present a clear picture of how much these programs are helping so that a sound conclusion regarding whether they are helping enough can be reached. STEP 3) Describe which side of the argument you feel is right and why I believe that given the current health care needs of the American public, serious consideration of establishing a universal health are system should be deeply considered. I also believe that current measures are not enough. Of course, these are assertions that Iââ¬â¢ve initially made based on personal experiences in my interactions with individuals seeking health care support from the government. Therefore, I would need to gather more solid, factual information to support my claims. I will need to explore the concept of a universal health care system better in terms of its application to other countries so that I can have a deeper perspective on what needs to be done. STEP 4) Formulate a working thesis sentence The development of a universal health care system is a positive step towards the solution of the American uninsurance problem.

Behind Closed Doors Essay -- essays research papers fc
Behind Closed Doors Over the years, many people have believed that the issue of sexual harassment should not be discussed in public. Sexual harassment was to be discussed behind closed doors. In spite of this, the social and political systems have changed instantaneously. This social problem has affected men and women throughout time; however, it seems that the women of our society more closely look at this issue. This social topic has encouraged women to establish organizations in order to help them discuss the issues more openly and to demand equality including fairness and justice throughout the workplace and in their social lives as well. In recent years, sexual harassment has been one of the most serious and widespread problems found in the workplace. For this reason, the Universal Declaration of Human Rights proclaimed, by the United Nations in 1948, to help everyone in their fight for self-respect and dignity. Indeed sexual harassment is an issue that complicates employment decisions. People also recognize that it is an issue involving the creation of an antagonistic or offensive work environment. In many instances, the issue of sexual harassment is not something minor that can be easily solved. Sexual harassment, in most cases, involves a superiorââ¬â¢s behavior towards a subordinate. As mentioned before, most forms of sexual harassment occur in the workplace. An employee can charge an employer with sexual harassment as a result of the misconduct of managers, fellow employees, vendors, and even customers. Eventually, sexual harassment can cause a hostile work environment. It is true, for the most part, that sexual harassment comes in many forms in the workplace. There are two significant ways in which one can identify sexual harassment. They are called the ââ¬Å"Quid Pro Quoâ⬠and the ââ¬Å"Hostile Environment Harassment.â⬠The essence of the Quid Pro Quo theory of sexual harassment occurs when an employee is confronted with sexual demands to keep her job or obtain a promotion. This is a true violation of the Civil Rights Act of 1964, which is also referred to as the Title VII Act. Even though sexual harassment by its very nature is complicated to define, the Equal Employment Opportunity Commission provides a general description of sexual advances.

Microbe Bug Report Candida albicans: Friend or Foe INTRODUCTION. Our bodies are made up of billions of living microorganisms. Most of these microorganisms are extremely beneficial for our health and actually contribute to our survival. However, if imbalances occur within, our naturally helpful microbes then they can become ââ¬Å"invaders and literal harmful. I will examine Candia albicans and its important role in the body and the consequence of their imbalance. RESEARCH & CLASSIFICATION. The genus Candia is a yeast group that has approximately 150 species that belong to the eukaryote domain. The cell structure is nearly identical to that of a human cell. Candida albicans is a diploid organism with eight sets of homologous chromosomes and a genome size of about 32 Mb. It is a dynamic organelle with cell walls composed of glucan and chitin. Various proteins also exist in the cell walls and can be modified by glycosylation, phosphorylation, and ubiquitination. Enzyme secretion occurs with substrates both within the cell and in the external environment. They are gram-positive; colonizing within 3 days and have a soft, moist, and yellowish-cream appearance that form 10 to 12 microns in diameter. Candida albicans fungus reproduces sexually and asexually in hyphal form in which they split into fragments and create new yeast-like forms (mycelia), and the other by budding and forming an ellipsoidal bud. ETIOLOGY & EPIDERMIOLOGY. Candia albicans is an endogenous organism that grows as a diploid fungus and is present in 40-80 % of human beings. It lives in our digestive tract and contributes to the population of our gut microbe by providing nutrients to our friendly gut bacterium. When the balance of C. albicans is at a healthy low ... ...roduce stable electrically conductive bio-nano-composite tissue materials that have been used as temperature sensing elements.

My Car Crash Crisis
How could my dad and brother survive without gravy with our Sunday dinner? Unfortunately the store cupboard was sadly lacking in anything resembling< ââ¬Å"Bistoâ⬠, none the less myself and my little sister were strapped into the back of Mum's car trying to find one of those little shops which my mum describes as ââ¬Å"life saversâ⬠for the working mother where she could purchase some gravy granules and ensure that peace reigned at the Sunday dinner table. I should add at this stage my mother was heavily pregnant with my little brother. I personally had no objection to this little excursion as it gave me the opportunity to get some sweets. Then again I was thinking I would probably get plenty of sweets at my friend Suzanne's party which I was due to go to that afternoon. I was really looking forward to Suzanne's party. All those different coloured balloons just waiting to be burst but little did I know that it was my ââ¬Å"happiness balloonâ⬠which was about to be burst. Mum was driving along the road and was pulling into her little Filling Station lifesaver. As we pulled across I saw a brown jeep heading towards us but it didn't seem to be slowing down. I was strapped in the back passenger seat and my little sister Kathy was in her baby seat I could hear my mum shout but I am not sure what she said. She tried to make it to the car park but even Michael Schumacher would have found it impossible. I remember vividly seeing the lady driver of the other vehicle. Her face was white and her mouth was open and her eyes filled with fear. That split second seemed to last forever and was only interrupted by the wailing screech of brakes. Time was once again frozen as my mind filled with questions-what would happen to my mum? -What would happen to my sister? -What would happen to me? All our lives were hanging on this frozen moment in time especially mine as the jeep was heading straight for the rear passenger door. The noise of metal striking erupted as pieces of the car door, the car pillar and a shower of glass made contact with my body. The front passenger seat came crashing backwards jamming my leg. Fortunately I was wearing my seatbelt otherwise I feel sure I would have gone either over my baby sister or straight through the window. I suddenly had a flash back of my brother and I driving along the road at the edge of a ravine where there was no fence at the edge of the road and I was frightened of our car falling down the steep mountainside into the valley below. My brother reassured me and told me that all I had to do was brace myself. I grabbed his cyber pet ad clung desperately to it. I could feel wet fluid rolling down my face and the screams of my little sister with her eyes scrunched up as she screeched uncontrollably. My mum was already out of the car at this stage and undoing our belts. I realised the fluid running down was in fact tears not blood. In the distance I could hear sirens blazing. As my mum continued to fumble with the seatbelts and try and extract my little sister and me from the car I saw a â⬠¦ smiling policewoman looking in at me. She offered me her hand but when I got out I realised I had forgotten my brothers cyber pet so I broke free from the policewoman's grasp and grabbed it. She then took me to the side of the pavement beside my mum and little sister and set us all on the adjoining wall. She reassured me that my mum, sister and I would all be okay. I began to shiver uncontrollably and my head started to spin and it was only then that I became aware of the gash on my leg. I just could not seem to get warm realising this a policeman came over and gave me his jacket whilst my mum phoned my dad and called him to the scene. I remember my mum crying, as she was concerned about my sister, her unborn child and myself. The lady in the other car was very supportive and friendly but I was so glad when dad arrived and took us home. My mum was very keen to take me to hospital to have me checked out but I could not bear to be taken anywhere strange or to be parted from my family. I just wanted the warmth comfort and protection of our own home. When we got home mum and dad cuddled us on the settee and gave us a warm blanket with cups of steaming hot chocolate thankfully our next door neighbour who is a GP came and tended to us. Thank goodness no one received any serious injury and my cuts and bruises soon healed. When I look back on the accident I feel very glad I had my seat belt on because otherwise my injuries would have been much worse and I am also glad my mum was driving a large heavy car which absorbed a lot of the impact but more than anything ever I realised something for the first time just how precious life is and that we should always try to enjoy each day.

What accelerates and counteracts global warming?
Global warming is the worst challenge facing the world in the 21st century. Since the second half of the 20th century, there has been sudden increase in global temperature leading to global warming effect. Increased human activities and natural activities have contributed to increase global warming.Global warming has had various negative effects in the world including melting of polar ice and rise in sea levels, changes in weather pattern with prolonged drought and torrents of rain, disappearance of species, and many others. One of the main factors that have contributed to global warming is release of green house gases to the atmosphere. Release of gases like carbon dioxide, carbon monoxide, nitrite oxide, and others has contributed to green house effect leading to global warming.Although green house gases has been cited as the main source of global warming, there are other minor sources which over the time has led toà substantial increase in global temperature. However, there are alternative factors counteracting global warming effects which include aerosols and soot, solar variation, and many others.Alternative causes of global warmingThe most common indicator used to indicate global warming is the change in average global temperature at the near earthââ¬â¢s surface.à Between 1860 and 1900 it is recorded that the earth surface temperature increased byà à 0.75oC which is approximately 1.35oF.Since 1979, the global temperature at the lower trosphere has recorded an increase of more than 0.22oC. Before 1850, it is believed that temperature was relatively stable for more than two thousands years and therefore it is the increase in human activities especially industrialization that has led to increase in global temperature. According to recent records, 2005 was recorded as the warmest year ever since the scientific world started keeping reliable records.The main factor contributing to increased global temperature has been release of green house gases to the atmosphere (Pierce and Adams, 2009). It is believed that gases like carbon dioxide, carbon monoxide, nitrite oxide, nitrogen dioxide and others leads to green house effects which increases global temperature.While green house gases contribute to global warming effects, it is believed that there are factors which had previously been thought to cause global warming but counteract global warming effects.Although their contribution may be minimal and difficult to notice, these factors can led to substantial cooling of the earth over a long period of time. Let us look at some of these factors including aerosols and soot which counteract global warming and solar variation which may accelerates global warmingAerosols and soot Aerosols and soot contribute to global cooling through global dimming. This is an effect in which there is gradual reduction in the range of direct irradiance to the earth that greatly counteracts global warming effect.This phenomenon, which has been studied s ince 1960 evidence that global dimming, can contribute to cooling of the earth over a long period of time. à Global dimming is mainly caused by aerosols which are produced through volcanic activities and other emissions like sulfur dioxide (Pierce and Adams, 2009).Aerosols produce a cooling effect through increase of reflection of some of the incoming sunlight. à à Through scattering and absorbing of the solar radiation, aerosols have also been shown to have indirect effects on the net radiation budget.For example sulfate aerosols have been found to form cloud condensation nuclei which lead to clouds having smaller could droplets. à The formed clouds have been shown to reflect solar radiation when compared to clouds with fewer and large droplets.Soot can lead to cool or warm effect on the globe depending on its state whether airborne or deposition. Soot aerosols in the atmosphere absorb solar radiation thereby cooling the earth since solar radiation heats the atmosphere.Howe ver, soot deposited at the glaciers has been shown to heat the earth surfaces.à Aerosols have more pronounced effects in the tropical and sub-tropical regions especially in Asia.
