Chilean Copper Mine Collapse Essay Example for Free

Chilean Copper Mine Collapse Essay On August 5, 2010 at San Jose mine in northern Chile a cave collapsed trapping 33 miners more than 2000-feet underground (Weik, n. d. ). This should have been just another day, a normal 12-hour shift at work, but it instead it turned into a 69 day nightmare. Minors did not know it would be the last time for nearly two months they would see the light of day. Miners, much like fire fighters and policemen, know there is a risk in the work they do. Their families also know that there is a risk and accept that someday they may get a call with bad news. Knowing this and seeing it happen are two different things. Communicating with the Families and Employees The families are from different backgrounds and different nationalities this should be taken into consideration when communicating with them. Minera San Esteban Primera would want to have several people involved in communication plan that involved constant communication with families as well as their employees. Some of the people involved with communications should be the same nationality and speak the same language to get the message across as well as make the families feel somewhat at ease. This will help the families feel as though someone understands them and their culture because they are from the same backgrounds. Communication should be organized and planned. The families from other places, not local, should be put up in a hotel with a meeting place provided where the families can come for regular updates. This will relieve some stress from the families having to wait by the phone for updates, and for the company getting calls unexpectedly or at the wrong time. This place could serve a dual function as a place where families can go and seek empathy with other families, Minera San Esteban Primera should communicate in-person with the families as much as possible. They should provide updates via phone calls with set times to call. Electronic communication would be for faster if the families have access to this type of information. Other considerations are the employees who may have family members who are trapped. It is common in a work environment like this to have several members of one family working for the same company. Other employees may be minors who called in sick that day or were assigned to different projects. Minera San Esteban Primera will need to consider how they talk to employees to be sure sensitive information is not out before it should be. Some employees who have to work around the clock to make sure everything is taken care of. The families and employees need to know that their employer will do everything they can to help the miners as fast as they can. They should hold small to the point staff meetings to provide updates to the employees (Aniisu, n. d. ). They could even have a room where employees can come and watch for updates as they become available. The country came together suggesting ideas on how to get to the miners. It was important to ascertain if the miners were alive, to see if rescue was possible. Chilean government reached out to NASA for the assistance in communicating with the miners and could get lines of communication going. Once the Chilean authorities could confirm that they were all alive, the vital information had to get to the families and to the employees (Condon, 2010). Once communication lines were set up, family members were allowed to talk briefly to their trapped miners (Tabor, n. d. ). Even though it was only one minute, it was essential for the family to see that the minors were fine and no one was lied to. This also helped the miners’ mental state and encouraged them to stay strong until rescued. The employees were able to see live feed of the miners that helped them to feel as though Minera San Esteban Primera, NASA, and the Chilean government were, in fact, doing everything they could do to save the miners. As further mining operations were bound to happen employees would feel confident that their company would do what was necessary to ensure their wellbeing in the event of another collapse.

Lifespan Development Essay -- Sociology Life Span Developing Essays

Lifespan Development   Ã‚  Ã‚  Ã‚  Ã‚  Going back forty-five years is not an easy task to complete because I can’t remember some of the finer details of my childhood. I know I was born on a hot August afternoon in Birth Year at Place Of Birth in City ands State. My mother was just twenty-two at the time and was already the mother of two, I was her third child. My father was twenty-one and already a workaholic, I know because my mother would constantly remind me not to be like that. My mother and father were good parents and they tried to give us the best upbringing they could. My father was the kind of person that believed he should provide and protect his family, and he did a very good job of doing that. During my pre adolescent years, as best as I can recall, my mother was the driving influence behind my development. She is a good person and a mother with an iron will and a strict way, and I believe that she was one of my first role models. My father played a part in my development also. He instilled in me the morals and values that I have today and I thank him for that. Unfortunately my father passed away thirteen years ago before I had a chance to tell him that. My brother and sister were influences as well. I have always looked up to my older brother because he was so independent and free as we were growing up. He would always take time and play with me and teach me things, he was the person that actually taught me how to write my name in cursive the first time. My sister...

Identifying the Genetic Material

Frederick Griffith, a bacteriologist, was trying to prepare a vaccine against the pneumonia-causing bacterium, S. pneumoniae. A vaccine is a substance that is prepared from killed or weakened microorganisms and is introduced into the body to protect the body against future infections by the microorganisms. Griffin worked with 2 types, or strains of S. Pneumonia. The first strain is enclosed in a capsule made of polysaccharides. The capsule protects the bacterium from the body's defense systems; this helps make the microorganisms virulent, or able to cause disease. Because of the capsule, this strain of S. Pneumonia grows as smooth-edged (S) colonies when grown in a Petri dish. The second strain of S. Pneumonia lacks the polysaccharide capsule and does not cause disease. When grown in a Petri dish, the second strain forms rough-edged R colonies Griffith knew that mice infected with the S bacteria grew sick, and died, while mice infected with the R bacteria were not harmed. To determine whether the capsule on the S bacteria were causing the mice to die, Griffith injected the mice with dead S bacteria. The mice remained healthy. Griffith then prepared a vaccine of weakened S bacteria by raising their temperature to a point at which the bacteria were â€Å"heat-killed† meaning that they could no longer reproduce ( the capsule remained on the bacteria). When Griffith injected the mice with heat-killed S bacteria, the mice still lived. Thus, Griffith knew it was not the capsule on the S bacteria that killed the mice. He then mixed the harmless live R bacteria with the harmless heat killed S bacteria. Mice injected with this mixture of previously harmless preparations died. When Griffith examined the blood of the dead mice, he found that the live R bacteria had required polysaccharide capsules. Somehow, the harmless R bacteria had changed and became virulent S bacteria. Griffith had discovered what is now called transformation, a change in phenotype caused when bacterial cells take up foreign genetic material. But the cause of the transformation was not known at the time. Avery's experiments An elegant series of experiments showed that the activity of the material esponsible for transformation was not affected by protein-destroying enzymes, but the activity was stopped by a DNA- destroying enzyme. In this way, almost 100 years after Mendel's experiments were performed, Oswald Avery and his co-workers, biologists at the Rockefeller Institute, in NYC, demonstrated that DNA is the material responsible for transformation. DNA had the instructions for the making of the capsule in the S strain of S. Pneumonia. III. Hershey and Chase Show that Virus Genes Are Made of DNA. Scientists knew that proteins were important to many aspects of cell structure and metabolism, so most of them suspected that proteins were the genetic material. They also knew very little about DNA, so they could not imagine how DNA could carry genetic information. A. Viruses reveal DNA's role Alfred Hershey, and Martha Chase, performed an experiment that settled the controversy. It was known at the time that viruses, which were much simpler then cells, are made of DNA ( or sometimes RNA) surrounded by a protective protein coat. Bacteriophage, also referred to as phage are viruses that infect bacteria. It was also known that when phage are able to produce more viruses, which are released when the bacterial cells rupture. Hershey and Chase knew that the only molecule in the phage that contained phosphorus was its DNA. Likewise, the only phage molecules that contained sulfur were the proteins in it coat. Hershey and Chase used these differences in chemical composition to carry out the experiment. Steps T2 phages were grown with E. coli bacteria in a nutrient medium containing either 35S or 32P E. oli were infected with either 35S- or 32P- labeled phages. The infected E. coli were mixed and then spun. Each layer was tested for radioactivity. The 35S label was found only in the upper layer containing the virus's parts. The 32P label was found mostly in the lower layer containing the E. coli. Upon infection, the phages protein coat falls away. They inject their DNA into the E. coli, causing the E. coli to make more viral DNA and proteins. These important experiments, and many others since, have shown that DNA is the molecule that stores genetic information in living cells.

Sample details Pages: 4 Words: 1124 Downloads: 2 Date added: 2019/10/10 Did you like this example? A significant number of critics across the world claim that Chinua Achebe does not represent women as active participants in his fictional communities he has been using across his works of literature. These criticism neglects womens contestation as male dominate both political and aesthetic as employed in the novel A Man of the People. The book foregrounds the political foibles of the unreliable narrator while overlooking how his traumatic encounter with the female agency has shaped in the narrative. Don’t waste time! Our writers will create an original "Obscured Feminism in a man of the People" essay for you Create order The book is set in an African country during post-independence where Achebe has succeeded in making his work fictional and sound real as well. The deviation into a description of national policies is due to a profound inability to accept women petition for multiple forms of gratitude. Therefore,   A Man of the People explores obstructions to African feminism as well as sexual politics.   The writer foregrounds homosocial context between Odili, the narrator and chief who displaces central preoccupation where women are misapprehended and their dismissal to the participation of national politics. The following essay discusses the role of women in the society based on the Chinua Achebe’s novel a man of the people how he portrays women in a different perception. The book puts a lot of emphasis on womens political subordination and aesthetic misrepresentation which emerges early in a political event. The removal of Edna from the politics and introduction of Odili into the political life reverberates all through the novel. Chief Nanga decides to sponsor Edna to go through education process thus being prepared as Parlor wife. Edna lacks mandate express her on who to marry; thus she agrees to be a second wife married following the native laws and customs. Therefore, women are demoted to the authority of the customary where they dont have any freedom to play any role in the society. Odili, the narrator, rehearses that women should be pressed into reformulated schemes where he describes Edna as a convert girl and a loose woman ( p.35). Achebe has significantly displayed Woman as a person with good advice. Women are always omitted from public discourse or are either allowed under restrictive forms of presentation. From the novel, Ednas intervention and her violent expulsion re-constellates her omission during their first political event as a kind of violence. It is this transfer from interruption to violence marks a different order of communication where actions of women cannot be discounted. Moreover, the restriction of participation by women its clear when Edna fails the intervention is explicitly compared to mamas intervention.   It is evidenced in the novel when Odili the narrator quarrels with his father at the time when his plans to marry another wife, Mama. He says that   Mama has persuaded him to negotiate for peace which can only be achieved through going down on his knees to ask forgiveness and therefore, making a peace offering of a bottle of schnapps, two bottles of White Horse and a bottle of Martel l (pg.36).   Therefore, women do not interrupt, but they intervene which is a dispute to secure peace among men. Marshal Achebes female character has been used to respond to gender omission and obstruction which interrupts male attempts at hegemonic control. Achebe portrays woman as a weak, humiliated and oppressed person in the society. Women contestation of the dominant social representation greatly addresses the construction of women sexuality and their education as well as maternal mortality. However, Woman is portrayed as an intelligent and educated person where Women such as Eunice in the novel are an economist by profession and Mrs. Akilo; a lawyer significantly differs from Edna and Mrs. Nanga precisely because the former do not education which is shortened by marriage. The other women verify how schooling has modified their life to fit wedding plans. Chinua Achebe redirects to the characteristics which define marriage of Edna, and Mrs. Nanga. For example, Mrs. Nanga was quickly forced to end education and marry chief Nanga. She is also humiliated and oppressed by her husband, Chief Nanga. Mrs, Nanga has no say over her husbands behavior of being a womanizer. Elsie, Jean, and Agnes are easily convinced to make love with Chief Nan ga ( p. 38). In addition, women are portrayed as mere objects which cannot communicate using the English language. Instead, they translate it from the vernacular language.   Mrs. Nanga is a simple woman character who becomes complex in her conversational closure. However, termination of women education for marriage does not make them passive cultures who do not understand the culture of heroic representation as well as the materiality of power that upholds it. Womens tends to mock these cultures financially where Mrs. Nanga criticize the education system while Edna exploits it. Throughout the novel A Man of the People by Chinua Achebe, Edna significantly manipulates Odili together with the men around her through playing damsel. Edna’s movements which are between placement and rejection of female child in the society vulnerable appear in several scenes of the novel. For instance, odili warning her against polygamous marriage when Edna says polygamous marriage is a way of a woman, but odil i sadly told her that an educated girl should not say such rubbish ( p.27). Women are not supposed to do the artistic works of cementing allegiances to the new national state in the society, but they are called to do soothing sentimental labor in the times of crisis. They are used for emotional energy on the national stage which is evidenced in the novel A Man of the People where Esther is selected to appear during the selection of Politicians widow as a cabinet minister during a political crisis. To sum up, this novel constraints entry of women into the political leadership which in return suggests for the repositioning among Achebe’s criticism? It is a satire of political culture where it is directed to an inability of men to engage in women participation in politics. Moreover, women are not imagined they can play a significant role in the policy, and thats why people take politics as the only aspirants. The diverse models of sexualized women and the political women contextualized the evidence preoccupied where Achebe diversifies the women models and the contest which emerges between the internationally circulating and the locally produced ideologies. These historical cases manifest the semiotic codes through which actors represent women in national politics as Achebe explores these systems through the novel dissertation. The book foregrounds the political foibles of the unreliable narrator while overlooking how his traumatic encounter with the female agency has shape d in the narrative. The book is set in an African country during post-independence where Achebe has succeeded in making his work fictional and sound real as well. Thus the issue of feminism is central to the novel.
