1) Factors that Influence the Health of the Community- Public health seeks to prevent environmental conditions such as: Asbestos exposure, lead exposure, radon exposure, mercury exposure, radioactivity and radiation, ground and surface water contamination, contaminated and abandoned wells, food- borne and waterborne disease, air contamination (second- hand smoke, molds, carbon monoxide, etc.), public health nuisances (e.g., animal control, noise pollution), occupational disease (e.g., farmer s lung, hearing loss, carpal tunnel) (Nies McEwen, 2015 p. 250-268). Nurse should promote environmental conditions such as: Clean air, clean water, safe food, environmentally sound management of solid waste, hazardous substances, sewage, and land; and homes, workplaces, recreational areas, and playgrounds that are free of environmental risks. Informing the community of services offered through their local county health department can assist the community in promoting a safe environment (Nies Mc Ewen, 2015 p. 250-268). Most county health departments employ an environmental specialist in addition to nurses. Testing kits for radon, water, etc. can be obtained for a small fee may even be free in some cases. The nurse should complete an environmental assessment indicating any concerns. Concerns and/or identified issues must be reported and handled accordingly. 2) Aggregates in the Community- Public health seeks to prevent problems in child and adolescent growth and development, suchShow MoreRelatedComparison of Public and Community Health972 Words Ã |Ã 4 PagesCOMPARISON OF PUBLIC AND COMMUNITY HEALTH Comparison of Public and Community Health University of Phoenix NUR/408 Michelle Hogsed July 7, 2014 .

Sammys unforgettable day. Men will do Just about anything to get attention from a pretty girl. John Updikes most popular short story A P, demonstrates Just what a young guy would do in the 1960s in that position. It explains a scenario of Sammy who is the main character, quitting his Job to seem like a hero to these three beautiful young ladies who happen to visit the supermarket where he works in. What Sammy doesnt realize is that his decision to leave his Job, might have some severe out comings not Just in the present but also for his future. Just by reading the first sentence, the reader can assume that this will be an interesting story. In walk these three girls in nothing but bathing suits (Updike 1026). Sammy seems to be surprised, and amazed by these three girls who have Just walked in his store. We will write a custom essay sample on John Updikes AP Summary or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page He specifically describes the girls beauties and flaws, and compares them to common items in the supermarket (Thompson 216). First, describing one and the other in very close detail, ranking them in their look. However, concentrates more on the leader (Saldivar 217). He separates one from the hree of them. She was the queen. She kind of led them, the other two peeking around and making their shoulders round (Updike 1026). He completely forgets about his duties while being a cashier and messes up a transaction he was having with this cash-register-watchers, who gives him a hard time for ringing an item twice. Thats how astonished he was by sight of this one particular girl who he decided to call Queenie. Sammy gives a detailed observation of the girls walking throughout the store and also the store itself, clearly proving with such descriptions hat he has been working in the AP supermarket for a long time (Thompson 215). Sammy impatiently waits for the girls to be done shopping and pick a register. The whole store was like a pinball machine and I didnt know which tunnel theyd come out of (Updike 1027). For his luck the girls decide to come to him for assistance, and as they checkout it is queenie who is doing the purchase. She purchases Kingfish Fancy Herring Snacks in Pure Sour Cream (Updike 1027). And Sammy starts to wonder how she would pay for it; she didnt have a bag or wallet, her hands were empty. Still with that prim look she lifts a folded dollar bill out of the hollow at the center of her nubbled pink top. (Updike 1027). As he sees her doing this, he is completely in utter shock and surprised. And after this event, thats when the story truly does get interesting. Lengel the manager of the store, and also a church teacher walks in the store and sees the three young ladies. Girls, this isnt the beach is what Lengel says to the girls (Updike 1028). Queenie quickly responds by clearing out that her mother had sent her for the item (Saldivar 221). Sammy felt hat what he said was unnecessary and inappropriate, however he stayed quiet and watched. Once the disagreement between the girls and Lengel began, Sammy begins to think(Thompson 216). And he sees a vision of what Queenie life is, and imagines her social status. Queenie had become for Sammy a form of what he felt was power (Saldivar 221). After Lengel and the girls finish their argument, Sammy quickly bags Queenies item. As the girl begins to walk away, sammy realizes he wants to be this heroic person and immediately says l quit to Lengel quick enough or them to hear. However, the girls did not hear his heroic act, and leave the store. However, I dont think he did this because he cares about how the manager made the girls feels, but as a way to impress the girls and get someone out of it. After realizing him quitting didnt do anything for him, he still went through with hit. The manager says Sammy, you dont want to do this to your Mom and Dad, (Updike 1029) which is true he doesnt he doesnt. However Sammy admits what he is doing is dumb and ays it seems to me that once you begin a gesture its fatal not to go through with 1029). This describes Sammys regret towards his actions of quitting, and immatureness. In this story you can see how the character develops a hate toward his Job, and how he realizes he isnt going anywhere by working in this store. He also has an option of either staying or leaving, and yet he stills decides to leave, even though his attempt to get the girls attention fails And I ask to myself, what if the girls would of gone to the other cashier, would of Sammy still quit? In my opinion, I think Sammys decision to quit was foolish. Not Just because he was trying to impress girls but because he wasnt thinking of his family, and the consequences. I also agree with Lengel the manager of the store, if a girl walks into a public place with Just a bathing suit, it is like practically walking naked. The society we live in today might not care about girls walking around their bathing suits, but in the 1960s I believe something like that was never seen. I dont think that quitting his Job for some girls that he didnt even know was worth it.

Freud's Seduction Theory Freud's Seduction Theory During 1895-1896 Sigmund Freud practiced psychoanalysis by listening to his women patients weave cryptic trails down memory lane, as well as trying to decipher them. What he uncovered was that something awful and violent lay in their past. The majority of psychiatrists in this era would have deemed their patient as a hysterical liar, dismissing their memories as fantasy. Freud strayed from the norm in the sense that he believed that these women were telling the truth. Illness did not befall these women due to their ?tainted families? , but because of the atrocities they faced as children. During April of 1896 Freud scraped all the theories, case histories and experience from the depths of his consciousness and manipulated it into written form. The presentation of his ideas met with silence from his colleagues. Despite the predictions of a tarnished reputation, Freud published his newfound theories in The Aetiology of Hysteria. Its title refers to Freud's theory that the basis of all neurosis stemmed from what Freud called ?infantile sex scenes?. This namely became to be known as the ?seduction theory?, the belief that these early childhood experiences were real, not fantasy created out of hysteria, and they had long lasting effects on the adult lives of those who suffered through them. The repercussions of his ideas, both innovative and perverse, earned Freud a seat in seclusion. But as the story goes, Freud eventually came to his senses about the seduction theory and gave up his aberration by publicly retracting his study. The accepted notion is that he literally had to banish the theory from his consciousness in order to move on to his more accepted work. Joined by other physicians, over a three year span, Psychoanalysis earned respect as a therapy and science. How does an innovative idea , supported by spirit and experience , come to be a belief , and then a regret ? And in the answer, lie my intentions and hopes for this paper. I seek to prove that Freud was intrigued by cases involving child abuse, incest as well as other sexually related cases. Upon turning the last page of this paper, the reader will understand that Freud did not develop the seduction theory overnight. Moreover, a gradual impact of his studies and surroundings eventually seeped through his skull and saturated the innermost cortexes of his brain, leaving his thoughts forever changed. Freud in Paris: The beginning of an obsession? Twenty-nine year old Freud ventured on a studious trip to Paris to wrap up his medical education while working under France's leading neurologist, Jean Martin Charcot (1825-1893) at the renowned Salpetriere hospital. Freud's stay in Paris lasted from October 3, 1885 to February 28, 1896. During which, according to Jeffrey Masson, ?Freud was exposed to literature attesting to the reality and indeed the frequency of sexual abuse in early childhood (often occurring within the family); furthermore, in all probability witnessed autopsies at the Paris morgue performed on the young victims of such abuse? (15). Freud has also made insinuations towards his studies in Paris have had a tremendous impact on his later works. Freud's mentor, Jean Charcot, in collaboration with Valentin Magnan, a well known French psychiatrist-produced an article in 1882 entitled ?The Inversion of the Genital Sense and other Sexual Perversions?. The article stresses that madness being taken into account as a factor in sexual accounts. Charcot is also said to have worked with Paul Brouardel on the study of rape in small children by adults. Their work, Les attentets aux moeurs, the last in his series, Cours de medicine legale de la Faculte de Paris, focused on the rapist, instead of the victim. (Masson, 34). The book contains several case histories, all full of horror. Brouardel also conducted autopsies at the Paris morgue. Freud has written several letters expressing his enthusiasm for Brouardel's work. Through examination of the following excerpt one is assured of Freud's participation in the autopsies. Freud writes: I abandoned my occasional attempts at attending other lectures after I have become convinced that all they had to offer were for the most part well constructed rhetorical performances. The only exceptions were Professor Brouardel's forensic autopsies and lectures at the morgue, which I rarely missed. -(Studies in

U10a2 Life Cycle of the Stars Paper - Essay Example Astronomers can determine the mass, age, chemical composition and many other properties of a star by observing its spectrum, luminosity and motion through space. The total mass of a star is the principal determinant in its evolution and eventual fate. Other characteristics of a star are determined by its evolutionary history, including diameter, rotation, movement and temperature. A plot of the temperature of many stars against their luminosities, known as a Hertzprung-Russell diagrams (HÃ¢â¬âR diagram), allows the age and evolutionary state of a star to be determined. Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years (for the most massive) to trillions of years (for the least massive, which is considerably more than the age of the universe). Stellar evolution is not studied by observing the life of a single star, as most stellar changes occur too slowly to be detected, even over many centuries. Instead, astrophysicists come to understand how stars evolve by observing numerous stars at the various points in their life, and by simulating stellar structure with computer models. Stellar Evolution: A nebula is a cloud of gas (hydrogen) and dust in space. Nebulae are the birthplaces of stars. There are different types of nebula. An Emission Nebula which glows brightly because the gas in it is energized by the stars that have already formed within it. In a Reflection Nebula, starlight reflects on the grains of dust in a nebula. The nebula surrounding the Pleiades Cluster is typical of a reflection nebula. Dark Nebula also exists. These are dense clouds of molecular hydrogen which partially or completely absorb the light from stars behind them. 1st stage of a stars life: PROTOSTAR Stellar evolution begins with the gravitational collapse of a giant molecular cloud (GMC). As it collapses, a GMC breaks into smaller and small er pieces. In each of these fragments, the collapsing gas releases gravitational potential energy as heat. As its temperature and pressure increase, a fragment condenses into a rotating sphere of superhot gas known as a prostar. Protostars with masses less than roughly 0.08Ã M (1.6?1029 kg) never reach temperatures high enough for nuclear fusion of hydrogen to begin. These are known as brown dwarfs. For a more massive prostar, the core temperature will eventually reach 10 million kelvins, initiating the proton-proton chain reaction and allowing hydrogen to fuse, first to deuterium and then to helium. The onset of nuclear fusion leads relatively quickly to a hydrostatic equilibrium in which energy released by the core exerts a "radiation pressure" balancing the weight of the star's matter, preventing further gravitational collapse. The star thus evolves rapidly to a stable state, beginning the main sequence phase of its evolution. A new star will fall at a specific point on the mai n sequence of the Hertzprung-Russell diagrams, with the main sequence spectral type depending upon the mass of the star. Small, relatively cold, low mass red dwarfs burn hydrogen slowly and will remain on the main sequence for hundreds of billions of years, while massive, hot super giants will leave the main sequence after just a few million years. A mid-sized star like the Sun will remain on the main sequence for about 10 billion years. . A star of less than about 0.5 solar mass will
