Philosophy - Essay Example Gene flow can happen either through hybridization or by exchange of DNA sequence by bacteria or virus. Bacteria and virus have the ability to transfer genes across specie. The gene flow can also result in the formation of a combined gene pool which will have both the characteristics of the two population groups. Thus the barriers to gene flow as well as the gene flow itself, both have the potential to bring about species diversity and take evolution ahead. Genetic drift is the change in the frequency of a DNA sequence, usually called allele. This phenomenon totally depends on chance. When a new member is born in a species, the alleles that will be taken up into the genetic make up of that individual will be through a process of random sampling. And if that individual lives enough to reproduce, only then there is an assurance that the specific alleles in his genes have a scope to survive. It is in this way that the allele frequency changes within a population and this leads to genetic variance within species. Thus a new generation may emerge which may either have lost one genetic trait or may have strengthened one genetic trait of the species, more visibly. Mutations are sudden changes in DNA sequence, of an organism, caused by many factors including, viruses, radiation, mutagenic chemicals, errors during DNA replication, transposition of DNA sequences within the genome, and errors in cell division while sexual reproduction. It has been proved that mutations have a great role in the process of evolution, that is, in the birth of new species, particularly, in smaller life forms like viruses and bacteria. But for higher life forms, mutations are harmful or neutral with respect to the survival of the specie. 2. Race is a social construct rather than a scientific classification. All human beings belong to the species, Homo Sapiens. The concepts and categories of race have not been constant and these have been changing in the history of human kind.

Enviromantal engneering project - Essay Example rmore, instead of excavating and transferring the contaminated soil to another site, this process proved successful as it was done on site- saving time and energy. Bioremediation- According to Prof. Shaily Mohindra of UCLA, conventional technologies for cleaning ground water are not always effective. Moreover, these methods usually move pollutants from one point to another. For that reason, Mohindra endorses Bioremediation using Pseudonocardia dioxanivorans bacteria for the mitigation of next generation pollutants e.g. Perfluorinated compounds, nano materials, and dioxane. The progress of remediation will be monitored usin stable isotopes. Pump and treat- The application of pump and treat technology in Hanford has been successful in soil and ground water remediation. By 2011, 24.7 billion gallons of ground water had been treated, although the whole process of remediation will be completed in the next 25 years. At the end of the remediation process Contaminants such as plutonium and i ts derivatives e.g. Carbon tetrachloride will be successfully removed from the soil and ground water. In situ thermal remediation- pump and treat technology had been used for more than 17years to clean up chlorinated solvents from the subsoil in Stuttgart with minimal success rates. However, in January 2013 an in-situ thermal remediation pilot test offered a suitable alternative for remediation even under prevailing difficult geological conditions in Stuttgart. Monitored natural attenuation- The Company was justified as it relied on natural processes to clean up the site. An environmental disaster similar to the silent spring has also been observed in Oregon (Lower Columbia). Since 1985, conservation centered on removing the nearly extinct bald eagle from the federal extinction list resulted in significant overall increase in bald eagle numbers. Yet, in lower Columbia most of the eagle nests in the lower Columbia failed to hatch eaglets; and have been producing half the number of

How do movies or television influence peoples behavior use reasons and Essay

How do movies or television influence peoples behavior use reasons and specific examples to support you answer - Essay Example The first thing to note is that both television and movies happen to be aa great medium through which artists talents are demonstrated throughout the world. Through TVs people receive world news. It is a source of entertainment too. Individuals get relaxed when they take time to watch films. Children as ell learn from TV as they watch certain channels such as fox history, discovery among others. These are just but a few of positive benefits of television ad movies that positively affect the behaviors of people (Mariam, 2013). On the other hand, most children take more time to watch television as compared to time spent on outdoor sports. Such behavior is unhealthy and results to diseases such as eyesight problems, obesity as well other diseases. Surveys have shown that those children who spent most of their time watching TV do not do well in class. They become addicted to watching TV and prefer watching programs over doing their school homework. This is more common today now especially that most children have in their own bedrooms, their TV sets. Most people think that if there is no bad content showing in the TV then there is no need to stop the kid from watching TV. This makes children love TV and become lazy in class. It is the idea of many people that movies as well as television reflect the society. However, this is not the truth mostly. Most people today like watching movies and TV programs that ha violence within the content. Criminals learn from movies new tactics as well as tricks which they apply in murder, robbery and other harmful activities. Most young people today engage in crime as an influence of TV and movies. Another thing is that through movies, the under aged are able to access porn material easily (Mariam, 2013). It is well know that the youth can watch a lot of stuff in their bedroom TV sets. The bottom line is that as advantageous as it is, the system has a huge negative impact on individuals’ behavior too. The fact is that

Market and Social Research - Essay Example The word frequently means daily in a week. Alcohol is the drug that many youths prefer; this is because of many young people like experimenting that leads to experiencing many consequences of too much drinking. As a result, underage drinking is currently rated the first public health problem in the country(Norman 2011, pg. 504). According to the latest survey of 2005 of monitoring the future, showed that youths as young as eight years were getting involved in drinking of alcohol. Moreover, when they drink they use to drink intensively, often consuming five to six drinks at one time. The research result showed that average age of engaging in the use of alcohol was 14 as compared to 17 years in1960 and serious drinking that was associated with middle age begun to appear during the young adulthood and occasional adolescence. In United Kingdom, many researchers have been done to answer the question why young adults get involved in binge drinking. One of the explanations was that; as adolescence move to young adulthood they occasionally encounter a full dramatic change in their lives. These changes include physical, lifestyle, independence and emotional changes. Such developmental transitions have associated them with drug use mostly alcohol abuse. Therefore just being a young adult is a risk factor for drinking dangerously(Courtney & Polich 2009, pg. 146). With the continuous rise of alcohol abuse among the young adults and teenagers, there is a need that should be taken to prevent the vice from escalating further. It means that the study must be performed to determine the knowledge and awareness of the population at risk of alcohol abuse, and the methods that can be used to prevent the vice. Some methods that can be used include; introducing stringent rules in pubs regarding drinking alcohol, collaborating with landlords to evict those young adults who are the worst drinkers, and changing the outlet to

Renewable Energy Essay Example for Free

Renewable Energy Essay Renewable energy is energy from natural resources such as sunlight, wind, rain, tides, and geothermal heat, these resources are naturally replenished. Renewable energy does not harm the environment or deplete any of our natural resources like fossil fuel. Renewable energy is not subject to sharp price changes because it comes from natural resources. Biomass is currently the largest U. S. renewable energy source with more than two hundred existing bio power plants providing energy for one point five million American homes, according to renewable energy specialist Davor Habjanec. The first time I heard the political differences about renewable energy was the last presidential debate. President Obama stated that he has and will continue to invest in renewable energy, like windmills and solar power. His opponent, Mitt Romney accused Obama of not using more fossil fuels found in America, from building a pipeline in Alaska to investing in oil and natural gas. Romney also claimed that the Obama administration was not expanding research of renewable energy. President Obama’s economic stimulus package included a number of incentives like thirty percent tax credit for renewable energy. Even though coal, oil and natural gas is limited and prices for it reflect that limitation there are still some disadvantages to renewable energy it cannot be stored like fossil fuels. Even though solar power can be stored for a short period of time and if there is no sun light for a number of days you will have no power from solar energy, same for wind energy. The research of renewable energy is very expense. With the economy being as bad as it is forcing cuts to be made in school programs and social programs some believe that we should not be investing so much in renewable energy. They do not dispute that investment in renewable energy does not create jobs. They believe that the same investment should be used on other parts of the economy and that investment will create more jobs and higher payback. According to the U. S. Bureau of Economic Analysis, a million dollars invested in job creation can generate nine point seventy-eight jobs.

Values of Nursing, Person, Health, and Environment

Values of Nursing, Person, Health, and Environment The values of nursing are acquired during socialization into nursing code of ethics, nursing experience, teachers and peers. Watson (1982, pp 20-21) outlined four important values of nursing; strong commitment to service, belief in the dignity and worth of each person, commitment to education and professional autonomy. Nursing education, concepts and programs for improving the knowledge in health facility are provided to maintain moral, theoretical and clinical values in the health setting Socalsy, 2008). The personal values of a person depends on the richness or intensity of the inculcation of knowledge, positive values and skills not simply based on the innate capacity of one to evaluate, think, reason and interact in a learning situation but the availability moral standards. It also equally depends on the quality of personal experiences which are either limited by the persons ability and will to choose or by what is desirable to her which is readily accessible in the environment (Craney, 2008). Health is valued automatically by an individual regardless of the existence of other personal priorities and values. People value health as important priority despite other things. Health considered as a good individual experience (Socalsy, 2008). Environmental Values is concerned mainly with the justification and basis of policy regarding the environmental. Its objective is to bring together the law, philosophy, economics contributions, which can be relate to the current and future of human environment and other living things; and to clearly understand the relationship between more fundamental underlying assumptions or assumptions and practical policy issues (Craney, 2008). Describe how teaching/learning best occurs? Compare the various levels of  nursing education? (LPN, ADN, BSN, MSN) The key to successful knowledge development is competent learning and effective communication during the practice to achieve the goal of competency. This will determine the path of being an effective and competent nursing professional. This is where the teaching and learning best occurs (Aikon, 2009). Approved practical or vocational nursing programs (LPN) are provided by community colleges, vocational schools, hospitals, or other independent health agencies. These programs usually last 9 or 12 month and provide both classroom and clinical experiences. License Practical nurse practices under the supervision of a registered nurse in a nursing home, clinics, hospital or rehabilitation. Taeching best occurs in this level through formal classroom instruction, students learned by doing, that is, providing care to clients in hospitals. Associate degree programs (AND) are offered in the Unted States primarily in community colleges although some 4-year colleges also have AND programs. The graduating student receives an AND or an associate of arts (AA) or associate in applied science (AAS0 degree with a major in nursing. Learning best occurs in through provision of specific information about type of knowledge, skills, and abilities of ADNs education program. ADNs currently function under t he same practice acts as BSN graduates. Todays baccalaureate nursing programs (BSN) are located in 4-year colleges and universities and are 4 to 5 years in length. The curricula offer courses in the liberal arts, sciences, humanities and nursing. Graduates must fulfill both the degree requirements of the schools or universities and the nursing program before being awarded a baccalaureate degree (Silber, 2003). The BSN program meet the learning needs of students through challenges and opportunity to pursue a self-paced, independent study or online programs. Masters degree program (MSN) provides specialized knowledge and skills that enable nurses to assume advanced roles in practice, education, administration and research. Todays masters program generally takes one and half to two years to complete. Learning best occurs in MSN program through provision of specialized knowledge and skills that enable student to have an advanced knowledge in practice (Aikon, 2009). Overview of what shou ld be some expected teaching knowledge, skills, and abilities. Name three goals for the first year of teaching? Nurses are expected to possess leadership skills, critical thinking ability, health promotion and case management skills in teaching. Their ability to be competitive in teaching satisfies a variety of learning. This improves knowledge as well as educational requirement, nursing practice and patient outcomes (Giovanetti, 2007). They provide sufficient information that will aid policymakers, practice leaders and researchers to recognize that entry level education makes a difference in nurses practice. Nurses should make them aware of every situation happening in the field and make it a motivational means to improve the profession by proper preparation and education. Possession of knowledge and competency in teaching interventions which can be acquired in hands on training is essential in practicing the profession (Silber, 2003). Goals for the first year of teaching includes; embracing of personal ethic of social responsibility and service, apply new knowledge of sciences, understand the role of primary care and continue to learn and help others (Aikon, 2009).

womenoed Essay on Sophocles Antigone - Sisters :: Antigone essays

Sisters Two sisters destined to love each other, but conflict interrupts their paths. The first's journey is one of self-exploration and discovery; the other's of continual oppression and hardships. Ismene and Antigone are the troubled sisters whose decisions take them on different courses, but these same choices also brought them together. Even though their actions show differently, Antigone and Ismene's morals and philosophies show that they are true sisters at heart. Antigone shows the attribute of boldness. She is constantly going her own direction. She is a leader, not a follower. "Ismene: What? You'd bury him when a law forbids the city? Antigone: Yes! He is my brother and- deny it as you will- your brother too."(61). This is where Antigone's boldness begins to surface. She is expressing her disagreement with King Creon's law. This is extremely daring of her to do because she is defying the law of the land. On the other hand, Ismene displays the quality of being a coward. She says, "Remember, we are women, we're not born to contend with men."(62). On the contrary to what Ismene's brain tells her to do, her heart is screaming to go and bury her brother, and defy Creon's dishonorable law. It is not until the middle to end of the play that Ismene's true self emerges and she agrees with Antigone. This is just one of the ways Antigone and Ismene are the same at heart, but take different paths to get to their real inner person. Another outstanding attribute of Antigone is her cleverness. "Antigone: Dear god, shout it from the rooftops. I'll hate you all the more for silence- tell the world."(64). This is in response to Ismene's promise to keep Antigone's burying of her brother a secret. Antigone's cleverness appears here because she found a way to publicly defy Creon and tell others how unjust he really is. Likewise, Ismene is intelligent and comes quick to understanding. In reply to Antigone's above statement she says, "Then go if you must, but rest assured, wild, irrational as you are, my sister, you are truly dear to the ones who love you."(64). Even though Ismene at this moment disagrees with her sister's action, she wittily understood Antigone's notion to want to collectively show her defiance of Creon. These to personalities of Antigone and Ismene also show their similarities in their philosophies.
