Comparative Analysis of Human and Chimpanzee Genome Research Paper

Comparative Analysis of Human and Chimpanzee Genome - Research Paper Example In justification of these new findings, molecular studies have been conducted and results have indeed shown that the two species exhibit some differential characteristics, mainly contributed towards genetic changes mostly on the human genomes, which have significantly contributed towards the differences in the genomes of humans and the chimpanzees. For a substantive period, scientists have always stated that there are substantive similarities between humans and chimpanzees. History has it that human beings and chimpanzees have at one time shared a common ancestor over 5 million years ago, eliciting research on the determination of the contribution factors towards such a development (Cheng et.al. 88). As science has revealed, the genome, which is the genetic material in an organism is the contributing factor towards the determination of whether an organism possesses certain similarities or differences to other. The genome is encoded in the DNA of organisms or RNA as in the case of viruses, which includes all the genes and the non-coding sequences of a DNA or RNA. From a comparison analysis of human and chimpanzee genomes, it is conclusive that despite the similarities that the two have had from sharing an ancestor, studies have ideally shown that significant changes have occurred in the genome sequences of the two species. That has indeed contributed towards the differences that are currently observed in both the human and chimpanzee genomes. Additionally, the genomic changes have also contributed towards the diverse changes in the phenotypes of the two species of organisms.

Development of Ophelia in Hamlet Essay Example for Free

Development of Ophelia in Hamlet Essay William Shakespeare in the play â€Å"Hamlet† develops the character of Ophelia in three unique stages. Initially, Ophelia is portrayed as a normal and obedient character. As the play progresses, she falls madly in love and ultimately goes insane. Ophelia progresses in a negative direction as the plot of the play moves on. In the beginning of the play Ophelia is depicted as the normal, obedient daughter. Laertes explains to Ophelia that even if Hamlet says he loves her, he may not be telling the truth. After Laertes speaks, Ophelia respects the personal knowledge on relationships that he has to offer. Ophelia accepts his speech and â€Å"shall the effect of this good lesson keep as watchman to [her] heart† (I, III, 48-49). Ophelia listened to Laertes’ advice and obediently accepts his guidance. Moment’s later Ophelia’s father, Polonius, requests that Ophelia stop seeing Hamlet. In response, Ophelia says, â€Å"I shall obey, my Lord† (I, III, 140). Polonius’ word appears to be of importance when Ophelia responds in such a compliant manner. Primarily, Ophelia is interpreted as a well-behaved teenage girl, however this depiction soon changes. Although Laertes and Polonius try to steer Ophelia in the right direction, she ends up falling almost irrationally in love with Hamlet. Ophelias utter obedience leaves her vulnerable to the abuse of Hamlet, who accuses her of being unfaithful and deceptive. Ophelia claims that Hamlet â€Å"took [her] by the wrist and held [her] hard† (II, I, 97). Although Hamlet physically abuses Ophelia, her love for him is stronger than him mistreating her. While Hamlet tells Ophelia that his love for her has departed, she is in utter shock and dismay. Ophelia responds with â€Å"O heavenly powers, restore him!† (III, I, 153). Ophelia cannot believe that Hamlet no longer loves her and wishes that he would love her again once more. Her love is clearly consuming her every thought. Although Hamlet no longer loves Ophelia she cannot accept or cope with this reality and the stress ultimately leads to her death. After Ophelia realizes that Hamlet no longer has feelings for her, she goes insane. Ophelia sings a vulgar song about a maiden who is tricked into losing her virginity with a false promise of marriage. While Ophelia is prancing around singing her outrageous song, she relates her song to Hamlet. Ophelia says, â€Å"Quoth she, before you tumbled me, you promised me to wed† (IV,V,62-63). Ophelia felt that they were going to get married and she believed that Hamlet was certainly going to propose to her. Later, Ophelia fell into the water and drowned. The Queen speaks up and says, â€Å"Till that her garments, heavy with their drink, pulled the poor wretch from her melodious lay to muddy death† (IV,VII,196-198). Rather than trying to save herself, she passively let herself drown because she didn’t care to continue living without Hamlet. In the end, Ophelia’s emotions controlled her, and these negative emotions led to her demise. Ophelia develops over the course of the play in a number of ways. Initially she is obedient and normal, and later turns into a girl controlled by love and eventually she commits suicide. Ophelia is a dynamic character that changes throughout the play. Her blind passion for Hamlet causes her to lose the ability to think or act rationally. Life, to her, is meaningless without him, and she chooses death over life. Ophelia surely progressed through the play in a negative manner.

A Modest Proposal for holding Fathers Equally Essay Example for Free

A Modest Proposal for holding Fathers Equally Essay Traditionally, the concept of abortion, child-rearing, home management, prostitution and even pornography are all attributed to women – women as subject. In the issue of abortion, women are more likely judged as immoral or not good parent for either aborting or not aborting her child (for certain reasons). In Child-rearing, the mothers are the very ones who are blamed if it happened that her children grew rebellious and defiant. Home management is in all likelihood tagged as women’s function. In the issues of prostitution and pornography, women are the central subjects for judgment. They are more seen as immoral as compared to how men are treated. In short, there are still unresolved problems regarding gender roles and gender biased structure of society. This essay addresses the issue of making fathers or men also accountable for the occurrence of such societal conflicts. Traditional Gender Roles By tracing our history, we could arrive at an evaluation that women and the mothers were discriminated in the society. Having a patriarchal structure of society wherein men or the fathers are labeled as superior over women or the mothers. The traditional structure inside the house was that the father was regarded as the head of the house whom has the highest authority. He has the final say in all things concerning the family. His well-established role as father was providing the needs of the family. Consequently, given such structure inside the home, the community and even the whole society became attached to that particular belief that only men or the fathers have the right to be the head or the bearer of the highest authority otherwise conflict would arise. Because of this traditional conception women and mothers were viewed as the destroyers of order and peace in the society if they would insist themselves as equal as or higher than men and the fathers. Recommendation According to Katha Pollit, the fathers should also be accountable for all the conflicts that arise inside the house, in the community, and in the society. (Barnet Bedau, 2004) They (the fathers) are not really attributed with perfect characteristics. They have also the predisposition of doing wrong things just like the mothers. When the marriage relationship failed, the mother should not the only one whom should be blamed. The father has also part in that failed relationship. When a child grew up as disobedient and rebellious, the mother is not the only one who is responsible for disciplining her child. The father, being also a parent of his child, has the responsibility of disciplining and molding his child’s attitude. In the case of abortion, mothers are not the only persons who make the problem. The father has also a responsibility towards the pregnancy of the mother. In this contemporary period, women are asserting and fighting for their equal rights with men. They are consistent with their campaign of establishing laws that would make them equal with men. In cases of parenting and marriage relationship, it is really unintelligible to say that only women have this responsibility of taking care and disciplining the children and working out their marriage life. The father has also such responsibilities toward his children and his wife. As a conclusion, all must be enlightened with the fact that everyone has a responsibility towards each other and towards the society. Men and the fathers are not exempted from this kind of responsibility. Women or the mothers cannot manage the home without the assistance and aid of her partner, the father or her husband. Both of them are responsible for molding and guiding their children. And truly, it takes two to tango. Reference: Barnet, S. , Bedau, H. (2004).

Preventing the Spread of Nosocomial Infections

Preventing the Spread of Nosocomial Infections Thomas Elliott   Nosocomial is a term derived from two Greek words: nosus meaning a diseaseor ailment and komeion meaning to take care of. By definition, nosocomial infections are those that are acquired by patients while under direct medical care. Nosocomial infections are a major safety concern for both medical professionals and their patients and have been linked to an increase in morbidity, mortality and an increase length of stay (Mehta et al., 2014). These patients require more therapeutic and diagnostic interventions, endure preventable suffering, and occupy scarce bed-days. This has a systemic effect on our medical infrastructure, forcing hospitals to spend more. Consequently, insurance companies bridge the gap by charging more for their benefits. Nurses have the responsibility of beneficence and play a crucial role in stopping the spread of nosocomial infections. It is the foundation on which our nursing procedures and techniques are grounded. The American Nurses Association (ANA) promotes e vidence-based practices that can be utilized by clinicians to prevent nosocomial infections so that, in collaboration with the Affordable Care Act, patients will have more knowledge about the care they receive, better outcomes and shorter hospital stays. Preventing nosocomial infections in patients is a major responsibility for nurses as well as other healthcare providers because it greatly reduces patient mortality, length of stay and health care costs. I worked with a 77-year-old male patient who was recovering from multiple ailments on the intensive care floor. He contracted ventilator associated pneumonia (VAP) after being on mechanical ventilation for 30 days. Upon treatment of his pneumonia, he developed multiple drug resistant organisms from his antibiotic therapy rendering his illness virtually incurable. Ventilator associated pneumonia is a nosocomial infection and patients have a 1%-4% chance of contracting this illness for every day they are on mechanical ventilation (Chastre Fagon, 2002). This disease is preventable and two questions have been formulated to explore strategies on its prevention: What is the most important aspect of patient care for the prevention of transmission of nosocomial infections and what patient p opulations are the most vulnerable? Aseptic technique is a procedural process by which a clinician establishes an environment that is free from bacteria, viruses and other harmful microorganisms in order to provide care to a patient. This technique is required anytime that a patients skin is perforated or when a sterile body cavity is entered such as when providing ventilator care (Schub Woten, 2015). It includes meticulous hand hygiene and the use of sterile attire and equipment. Approximately one third of nosocomial infections occur when aseptic technique is not followed and is transmitted from patient to patient through direct contact by a healthcare provider (Lewis et al, 2011, p. 240).   Because a large portion of nosocomial infections are transmitted by healthcare providers, proper hand washing and the use of protective equipment are the single most important measures in infection control (Saloojee Steenhoff, 2001). The hands are the most common way microorganisms are transmitted between patients, so it is imperative for health care providers to wash their hands vigorously for 15 seconds before and after leaving the room and when moving from one task to another (Mehta et al., 2014). These guidelines are backed by evidence-based practice and are established to protect patients, especially those who are the most vulnerable to infection. Patients receiving health care are exposed to a variety of different microorganisms from clinicians, other patients and even from hospital visitors. Susceptibility can be attributed to both intrinsic and extrinsic factors. The most important intrinsic factor that determines susceptibility towards acquiring nosocomial infections is age. Older adults and the elderly population are two to three times more likely to develop nosocomial infections than the younger population (Lewis et al, 2011, p. 240).   Typically, the elderly have more comorbidities, are more immunocompromised and have longer hospital stays which increases their chances of developing nosocomial infections. Extrinsic factors include surgical or invasive procedures such as the use of a ventilator, organ transplants, implanted foreign bodies or immunosuppressive medications and personal exposure. These extrinsic factors bypass the normal defensive barriers of the skin and mucous membranes, providing foci where organi sms can flourish. Both intrinsic and extrinsic factors can be controlled by healthcare providers through the application and knowledge of evidence-based infection control practices such as aseptic technique. Patients have very little control over the factors that affect their health during hospitalization and rely on the healthcare providers to stay diligent. The Affordable Care Act (ACA) in coordination with the American Nurses Association (ANA) has implemented strategies for clinicians to both reduce the likelihood of nosocomial infections and empower patients with knowledge regarding which hospitals provide the safest practices. The Affordable Care Act (ACA) was established to provide health insurance for all Americans and to equip them with adequate knowledge regarding the risks and benefits of where they are receiving their care. Although patients covered under the act will not need to pay out of pocket for the treatment of nosocomial infections, they will need to pay for insurance claims related to medications, follow-up care, lab work and rehab. These claims can drag on for years. Because patient safety is a top priority, the ACA has rolled out a mandate which requires hospitals to be held accountable for nosocomial infections. This includes improving infrastructure, insurance requirements as well as reduced payments from Medicare and state Medicaid programs.   The ACA has also established a uniform online reference center for the public to utilize which allows them to check the prevalence of nosocomial infections at their local hospitals. Patients can then make educated decisions on where they ar e likely to receive the safest healthcare. Patient perception of the environment and care they receive is tied to financial incentives for hospitals which is measured by patient satisfaction surveys. The survey includes questions that ask patients about the perceived cleanliness of the hospital, quality of care and if they would recommend the specific hospital. These elements included in the ACA are designed to protect, educate and to empower patients to make the right healthcare decisions. The American Nurses Association (ANA) as well has developed evidence-based guidelines for nurses and other healthcare providers to utilize in order to prevent nosocomial infections and improve patient outcomes. Emergent threats to patient safety, such as nosocomial infections, during a hospital stay require nurses and other healthcare providers to be equipped and educated with the latest research to protect themselves and their patients against infection. The ANA in collaboration with the Centers for Disease Control and Prevention (CDC) have developed a specialty organization called the Nursing Infection Control Education Network (NICE Network) which provides training courses for nurses to improve adherence to infection prevention practices. This program keeps nurses up-to-date on the latest research regarding infection prevention such as vigorous hand washing for 15 seconds and the use of gloves, gown and a mask when working in a sterile environment (ANA, 2017). These measures are aimed at reducing healthcare costs for patients and for improving their outcomes. The ANA described this method of care through the use of an inverted pyramid of priorities. This model represents primary care as the foundation of our nursing practice and should be the highest priority for providing care by focusing on prevention of complications and adverse events (American Nurses Association, 2008). This shift of thinking requires nurses to assume a more holistic approach to their practice not only by focusing on the physical ailment of the patient but in caring for the entire person. In so doing, nurses reduce their risk of inadvertently transmitting nosocomial infections to their patients while providing care for another reason. Health care is becoming less accessible and more expensive for patients so it is imperative that providers stay diligent and safe with their practices as to not deter people from seeking medical attention. Nurses and other health care providers do not intend to spread disease but unfortunately, they become the vectors and can spread infection to their patients without knowing it. This is why the ANA has implemented simple, evidenced-based preventative strategies to be taught in the form of classes to significantly reduce transmission rates and to increase compliance with and adoption of safest evidence-based practices by health care providers. The ACA has established a form of accountability for hospitals along with providing the general public with information regarding nosocomial infections at their local hospitals. These measures have been implemented to protect our patients, especially the most vulnerable from acquiring these infections and to reduce the overall rate nationwide o f nosocomial infections.

Eudora Welty:Worn Path, visit of charity :: essays research papers

Eudora Welty   Ã‚  Ã‚  Ã‚  Ã‚  The are only so many ways an author may sum up the course of a human life within just a few pages. Eudora Welty has the awesome talent of being able to do just this. In her stories â€Å"Where Is the Voice Coming From†, â€Å"A Visit of Charity† and â€Å"A Worn Path†, Welty uses the reoccuring themes of characterization, confrontation, journey, and insight into ones mind to convey key aspects of her stories. Through characterization Welty shows individuals who experience confrontations, and as a result complete a type of journey.   Ã‚  Ã‚  Ã‚  Ã‚  With a chillingly cold attitude, the protagonist of â€Å"Where is The Voice Coming From† takes it upon himself to take care of what he feels to be an inconvenience in his life, by murdering a local civil rights activist in cold blood. He later states, â€Å"I done what I done for my own pure-D satisfaction† (â€Å"Where is The Voice Coming From†482). This embodies the protagonist as a cruel, racist, self righteous murderer. One later is drawn to the conclusion that the only regret that the protagonist has is not getting the credit he believes he deserves for his crime.   Ã‚  Ã‚  Ã‚  Ã‚  With the knowledge of her deathly ill grand son at home, Pheonix Jackson decides to head for town to receive medication for him. In her travels the reader is given a real insight into the person that Pheonix really is. While crossing over a fallen down log, Pheonix jovially remarks, â€Å"I wasn’t as old as I thought† (â€Å"A Worn Path†636). One must realize the amount of strength and determination it must take for this frail old woman to accomplish such a task, yet Pheonix takes it with a grain of salt and keeps on going. At this point the reader finally realizes the respect that Pheonix deserves for being the beautifully harmonious person that she is.   Ã‚  Ã‚  Ã‚  Ã‚  In another work of Welty’ we are depicted the character of a seemingly kind, charitable young Campfire girl, named Marion, who is sent to an old age home. Yet what we do not know is that Marion has another side to her besides the bright, vibrant young girl that she is. We soon come to see this side of her as she sprint from the old folks home, â€Å" Under the prickly shrub she stopped and quickly, without being seen, retrieved a red apple she had hidden there.† (â€Å"A Visit of Charity). The reader now realizes the true conniving ways that Marion withholds in the beginning.

A Developing Epidemic in Argentina :: Buenos Aires Journalism Influenza Health Essays

A Developing Epidemic in Argentina BUENOS AIRES, Argentina--December is one of the loveliest times of year in the southern hemisphere of South America. On a typical summer day on a warm, Sunday afternoon, residents of Buenos Aires enjoy a relaxing jaunt along the Avenida de Mayo where one can browse the numerous shops of rare antiquities or simply retire to drinking tea in front of one of the many cafes along the avenue. Families with boisterous children picnic within the many public parks and gardens and bask in the warm sun. Expecting to revel in the long days of summer, I was surprised to find that these scenes that danced in my memory, while fighting sea-sickness en route, have vanished along with the citizens of Buenos Aires. The streets of the city are quiet, day and night. This proud South American city with its traditional colonial origins and its progressive embracement of modernity has become a ghost town of fear, fear of the illness that U.S. citizens know as the Spanish Influenza. According the local authorities, the origins of Influenza was brought by ships traveling from North American ports to Buenos Aires. Currently, port authorities have been cautious with the admission of foreign vessels and have established a quarantine period prior to entry. U.S. clipper ships the Elsie and the Snowdon, along with the steamer, the Royston Grange of Edinburgh have been subject to this quarantine which not only limits their admission into port, but also places an embargo on certain perishable goods. These actions have provided dire consequences for the local economy. Because of a lack of foreign goods, many dock workers are jobless along with local merchants facing scarcities which have greatly inflated the price of certain foods. While this is a serious economic situation, authorities of Buenos Aires feel justified in their restrictions and cite current statistics related to the spread of influenza. As of last Monday, the civil registry in Buenos Aires reported that in one district, as many as 192 deaths from influenza occurred just on that day. Because of this large amount of death, the local cemetery was unable to offer proper burials to 155 of those victims. City leaders are beginning to realize that preventative methods are the best means of defense against influenza. Public address messages about personal hygiene are published in papers and broadcast on the radio.

Where the Red Fern Grows by Wilson Rawls Essay -- essays research pape

Where the Red Fern grows   Ã‚  Ã‚  Ã‚  Ã‚   A novel by Wilson Rawls named Where the Red Fern Grows is the story of a boy, his two hounds (which he named Old Dan and Little Ann), and all of the adventures they shared together. A loving threesome, they ranged the dark hills and river bottoms of the Cherokee country. Old Dan had the brawn, Little Ann had the brains, and Billy had the will to train them to be the finest hunting team in the valley. Glory and victory awaited them, but sadness waited too. Close by was the strange and wonderful power that is only found Where the Red Fern Grows. An exciting tale of love and adventure one will never forget. Some themes that will be encountered in this novel are the passage from youth to maturity, the rewards of hard work and diligence, and working together to achieve common goals. All of these themes and more can be found in the novel Where the Red Fern Grows.   Ã‚  Ã‚  Ã‚  Ã‚  One theme illustrated in this novel was the passage from youth to maturity. An example of this is when Billy stopped asking for two hounds and saved up enough money to get them himself. He sold items to fisherman at very low prices but he was determined and would also take any offer they would give him. Another example shown is when Billy bought everyone something from Tahlequah with his own money. A normal child would but himself lots of candy and seldom share it but Billy didn’t. He bought his mom cloth, his dad overalls, and his sister’s candy. This example greatly showed the passage from youth to maturity. Another example depicted was when Billy made a promise to his dogs that the first coon they treed he would skin so when his hounds put a coon up the biggest tree in the forest, Billy didn’t walk away from the fact that it was very tall and started chopping the tree down and didn’t give up until the coon was skinned unlike a child who would have no patience and be careless. One last example is when Billy took the death of his dogs like a man and buried them in the nicest spot in the Ozark Mountain Ranges. He cared very much about his hounds and wanted them to have a very comfortable and happy afterlife unlike many others which would have just thrown the hounds off a cliff or do something unpleasan... ...f it wasn’t when Billy, Old Dan, and Little Ann worked together, someone could have been brutally ripped apart or even maybe everyone could have died at that very moment in the dark and lonely mountain ranges of the Ozark Mountains. So even though good happenings were on there way to Billy, hardships were right behind and if it wasn’t for working together , none of the happiness, joy, and/or jubilance would have occurred.   Ã‚  Ã‚  Ã‚  Ã‚  In conclusion, Where the Red Fern Grows by Wilson Rawls was a jubilant yet at the same time melancholy tale about a boys adventures with two hounds. When Billy received his hounds, his whole life changed. He had he best two dogs in the Ozarks and he proved it at the coon-hunting tournament. Nothing mattered anymore. Old Dan and Little Ann opened the door to Billy and Billy walked through it with no fear. Then, suddenly, when everything was going fine, something tragic occurred and all of Billy’s dreams were thrown away at an instant. All of this and more could be found in the loving tale of Where the Red Fern Grows.   Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚
