Francis Bacon s Philosophy On Science - 863 Words
Francis Bacon In this context of a philosophical essay, the focus shall be on the major philosophies, Francis Bacon developed upon exposure and interests in the various field. He was a philosopher whose origin was from England and throughout his life he sought to find answers to various issues relative to his character of being a man of high ambitions like attaining high political positions just like his father (Hammer, 74). His passion for philosophy has over the decades and centuries found its ways to the hearts and blossoms of philosophy scholars and publications. He developed philosophies that circled around nature, science and religion through his brilliant and most excruciating work of art of designing an effective method of learning, that is, the inductive learning methodology and a well-structured proposal of learning curriculum as is discussed below. Baconââ¬â¢s philosophy on renaissance has been stated on a different and elaborate way of perspectives and discussions. Bacon is reported to have discussed the major discoveries and theories based on the religion and science to have not been developed on a realistic approach (Robertson, 23). Relative to renaissance, Bacon tried to mean that these theories were only based on the past and not the present and the future and that Aristotle and others should have established common principles to curb the diverse and contrasting information published in books, journals and other reading materials. He further documented that it isShow MoreRelatedFrancis Bacon : Pioneering Scientific Philosophy1513 Words à |à 7 PagesFrancis Bacon: Pioneering Scientific Philosophy Francis Bacon demonstrated true brilliance in a time where people were finally starting to be curious about the world.

Fossil Fuels Coal, Petroleum, And Natural Gas - 756 Words
Fossil fuelsââ¬âcoal, petroleum (oil), and natural gas ââ¬â are concentrated organic compounds found in the Earthââ¬â¢s crust. They are created from the remains of plants and animals that lived millions of years ago in the form of concentrated biomass. According to the US Energy Information Administration (EIA), fossil fuels meet 81 percent of U.S. energy demand. Scattered records of the use of coal date to at least 1100 BC. By the middle Ages, small mining operations began to spread in Europe, where coal was used for forges, smithies, lime-burners, and breweries. The invention of fire bricks in the 1400s made chimneys cheap to build and helped create a home heating market for coal. Coal was firmly established as a domestic fuel in much of Europe by the 1570s, and represented the major heating source for buildings, especially in cities located far from easy access to less energy-dense biomass forms. Coal was the first of the fossil fuels to go into widespread use, displacing low-energy firewood as the leading source of fuel in the US, and triggering the countryââ¬â¢s industrialization in the second half of the 19th century. Within a few decades, the US went from a net importer of coal (mostly from Britain) to a major exporter of the fossil fuel, a development made possible by mining the nationââ¬â¢s vast reserves of coal. Oil was used in architectural adhesives, ship caulks, medicines, and roads in Mesopotamia around 3000 BC. Two thousand years later, the Chinese refined crude oil for use inShow MoreRelatedDepletion of Non Renewable Resources of Energy1422 Words à |à 6 PagesAà non-renewable resourceà is aà natural resourceà which cannot be produced, grown, generated, or used on a scale which canà sustainà its consumption rate, once depleted there is no more available for future needs.

Critical Analysis of Leah HealthNursing Research
Question: Write about theCritical Analysisof Leah's Healthfor Nursing Research. Answer: Introduction The WHO reported that as many nations are showing continuous advancements in combating most chronic diseases, there is a great challenge associated with abdominal obesity (Carmienke et al., 2013). Abdominal obesity presents risks to acute myocardial infarction amid adults. However, recent studies indicate that adolescents present significant values (DiCenso et al., 2014). The primary reason alludes to the environmental and genetic factors, but of late modifications in the lifestyle of most teenaged individual's records increased cases (Ford et al., 2014). Therefore, Leah a twenty-one-year-old student at an Australian university presents to the student undertaking placement at the school clinic with abdominal obesity. After engaging with Leah, the student notes that the underpinning factor to Leah's condition is a change in the social life that affects her exercise and eating habits (Richardson-Tench et al., 2016). As such, ideas in this paper seek to illustrate how Leah's personal ci rcumstances act as a barrier for application of evidence-based practices. Additionally, the article pays attention to matters research aligning with the PICO question. Further, the paper has several sections that critically analyze the works of several authors. Finally, the study will provide a succinct summary of the discussed ideas concerning the thesis statement and provide an opinion for future reference as shown below. Authorship Rogerson, Soltani Copeland., 2016; Share et al., 2015 are professors presenting with a broad field of health sciences expertise amid several universities in Australia. The authors have affiliated lectures to several institutions. Such institutions include but are not limited to "School of Exercise Science, Australian Catholic University, Melbourne, Victoria, Australia. School of Exercise Science, Australian Catholic University, Melbourne, Victoria, Australia; Murdoch Childrens Research Institute, Melbourne, Victoria, Australia." Regarding conflict of interest, the authors had different opinions on matters weight loss and the model of study employed. Rogerson, D., Soltani, H., Copeland, R. 2016 is of the opinion that structured interviews served a significant role in soliciting information from the participants. Further, the author stipulates that environmental factors played a significant role in causing abdominal obesity. On the other hand, the works of Share et al., 2015 employed a linear mixed model to study the participants. Moreover, the author is of the opinion that it was difficult to make judgments on the participants' health regarding physical activity and nutrition, but after some time it was evident that exercising and good eating habits reduced abdominal obesity. Notably, it is evident that the participants in the two study were different. In the study by Rogerson, D., Soltani, H., Copeland, R. 2016 the participants were from both genders whereas in the study by Share et al., 2015 the participa nts were all females. Research Aims According to Rogerson, D., Soltani, H., Copeland, R. 2016, the study aimed at investigating a sample of participants who were subjected to environmental factors; without alignment to clinical interventions. The works of Share et al., 2015 aimed at assessing the impact of a twelve-week multifaceted lifestyle program on cardiometabolic risks associated with abdominal obesity. First, Rogerson, D., Soltani, H., Copeland, R. 2016 employed use of semi-structured interview to assess the participants and collect data. The sampling technique used was purposive where data saturation guided the sample size. Theoretical underpinning using realist meta-theory enabled in-depth analysis of the participants' experiences and opinions. Then the data was analyzed using framework analysis. According to Share et al., 2015 employed a participatory linear model to study the group. Twenty-six women aged 18-30 years were sampled and introduced t a twelve-week lifestyle involvement program. During the progr am, cognitive behavioral therapy, biochemical, nutrition, and fitness testing were completed. The results were calculated concerning the waist-hip ratio and waist height ratio. Design Rogerson, D., Soltani, H., Copeland, R. 2016 used a problem-oriented research methodology characterized by inclusion semi-structured interviews. Theoretical underpinning using realist meta-theory served as the method to calculate and explain the results. Share et al., 2015 used a phenomenology research methodology in a twelve-week lifestyle intervention program. The study involved taking notes of the waist-height ratio and wait-hip ratio to determine the waist circumference f the abdominal obese participants. The research methodology and method remained relevant to the aims of the study according to the scholars' works. Rogerson, D., Soltani, H., Copeland, R. 2016 was able to justify the causal agent of abdominal obesity regarding environmental factors within the study group made up of eight British volunteers. The problem-oriented research approach and use of semi-structured interviews indicated the participants view regarding abdominal obesity: most of them were of the opinion that weight loss is challenging both mentally, emotionally, and physically (Greenhalgh et al., 2017). The model of Share et al., 2015 is relevant as the findings indicated the relationship between physical activity and nutrition and weight loss as being an effective mechanism in combating abdominal obesity. In the study by Rogerson, D., Soltani, H., Copeland, R. 2016 the participants were eight British volunteers of both genders aged between 30-50 years of age. The study by Share et al., 2015 had twenty-six participants aged between 18-30 years. Findings According to the works Rogerson, D., Soltani, H., Copeland, R. 2016: The results indicated that all the participants had a clue about weight loss and the risk factors associated with abdominal obesity. Further, the participants were aware of the importance of enrolling in an exercise program and the need for observing healthy eating habit. However, the results indicate that no participant was involved in a weight-loss intervention research. The conclusion asserts that cognitive, physical, emotional, and social factors were responsible for the reduced rate of exercise engagement for the participants. Therefore, rendering weight loss a challenging program. Regarding the works of Share et al., 2015: The findings indicate that there is increased rate of abdominal obesity amid adolescents. The result justified the rationale when a group made up of twenty-six women aged 18-30 years is studied. Further, the results indicate that lack of lifestyle intervention research and programs expose teens to risk factors of acute myocardial. The conclusion indicates that after the implementation of the twelve-week lifestyle intervention program the participants had reduced waist circumferences. Also, it is possible to discern that the study made use of observation skills and studied behavioral patterns amid the participants to understand their wait-list. As such, it is evident that the two studies are relevant and specific in answering the research question and justifying the study aims. Leah's Circumstances as a Barrier to Application of Evidence Leah is an outgoing person who treasures partying. Moreover, Leah is socialized within the new demographic location and deviates from attending the gym and eating healthy meals (Hoofman et al., 2013). The idea of Leah having a part time job supports her partying life. Due to self-criticism, Leah realizes that she has drastically increased weight around her abdomen. It is to such evidence that Leah seeks medical intervention from the school clinic. However, it is difficult to apply evidence lifestyle intervention to Leah since the evidence-practice calls for personal commitment from Leah (Schneider and Whitehead, 2013). Additionally, implementation of the intervention is a long-term program that will reduce her waist circumference while negatively influencing her social behavior (Ladabaum et al., 2014). Notably, research shows dealing with an alcoholic call for rehabilitation where therapeutic interventions are offered: From the literature provided, Leah is not anywhere near to resort ing to the same (Kelishadi et al., 2015). Therefore, it is difficult to implement the evidence approach due to her behavioral and social life that are more expressed than her zeal to reduce the waist circumference. Research Alignment with the PICO Question The research aims at creating awareness on the risk factors associated with abdominal obesity. Additionally, the two research studies provide platforms for the discussion on matters exercises, healthy eating, and weight loss. For instance, the works of Rogerson, D., Soltani, H., Copeland, R. 2016 indicated that most of the participants were aware of exercises and healthy eating habits as control measures to reducing abdominal obesity but none was willing to engage in the intervention research. The same is the ideas presented by the PICO question where most university students are affected by abdominal obesity due to reduced exercises and poor eating habits. Further, increased social behaviors such as partying and alcoholism are responsible for the increased cases of abdominal obesity amid university students (Smith, 2015). Conclusion To that end, it is possible to discern that abdominal obesity is health disorder that can affect anyone. However, adolescents due to their social and behavioral patterns present increased cases. For instance, Leah represents a majority of teenaged students who are affected by abdominal obesity due to poor eating habits, reduced exercises, and increased clubbing and alcoholism. Further, from the discussion above, it is evident that both environmental and genetic factors present risk factors associated with abdominal factors. Additionally, for implementation of evidence-based intervention calls for an understanding of an individuals' behavior, social patterns, cultural, and economic aspects. As such, a clinician can formulate a lifestyle intervention program that favors the victim regarding cost efficiency, personal behavior, traditional beliefs, and the social networks. Therefore, to promote recovery and well-being of persons with lived experiences of abdominal obesity, it is consider ed wise to engage clinicians, patients, and the community to support the application.

Apparent altruism in non-human animals Essays
Apparent altruism in non-human animals Essays Apparent altruism in non-human animals Essay Apparent altruism in non-human animals Essay Altruism can be described as an act or behavior in which is advantageous to another but at a cost to the organism carrying it out. Apparent altruism is the concept that although a behavior may seem to be fully altruistic or selfless, there is actually a benefit gained by the individual implementing the act. Charles Darwin, he who initially presented the Theory of Evolution in 1859, was bewildered about the reasons in why altruism occurs between animals. Part of his problem was that he did not have any knowledge concerning genetics. He believed that all characteristics in living organisms were solely passed on by a process of blending. He also believed that individuals lived to reproduce. Hence, if a parent, say a mother bear, were to protect her cubbased on his theory it would not benefit her in any way, as it would not increase her ability to reproduce later on. After Darwin passed away, however, many theories emerged and became the many explanations in why altruism takes place in n on-human animals. One of the great problems of Darwins theory of evolution was its incapability to justify the development of the queen bee and sterile worker bees. How could such a group evolve if its members could leave no offspring to breed the sterile worker traits? In 1963, Hamilton resolved Darwins paradox by presenting the Kin Selection Theory. His theory states that any individual that pass on genes to the future generations is performed, not only by means of their own reproductive success, but also by improving the reproductive potential of their relatives. Hamilton (1963) established the term inclusive fitness to describe the degree to which apparent altruism is shown depending on the genetic relatedness between individuals. The relatedness between a parent and a child is 1/2 (as the child will inherit half of each parents gene); siblings relatedness is 1/2, also regarded as offspring equivalents; a grandparent and a grandchild, 1/4, and so on. According to this theory, the closer the inclus ive fitness, the greater the cooperation and altruism. Kin Selection explains situations such as the reproductive altruism in social insects. Female worker bees forgo their reproduction ability to nurse queens young. By doing so, they increase their inclusive fitness by more than 1/4 (however always less than 1/2, as it would never reach to the mother-daughter point). This would seem more reasonable than if any female worker bees decided to leave the hive, reproduce on her own and in the end, losing all of her inclusive fitness to zero as a result of losing all protection, warmth and food from her hive. In 1981, Sherman observed Kin altruism between Beldings ground squirrels. It was such that close-related squirrels (such as mother-daughter, sister-sister relationships) did not show any aggressive behavior towards each other; it was even observed that they often helped each other in defending their young ones and sign alarm calls at the sight of predators, while unrelated females were observed to be highly aggressive. In North Mexico, female nurse prairie dogs feed offspring belonging to her siblings. The female prairie dogs give up resources belonging to them and provide it their siblings offspring because as they keep them fed and fit, she increases her inclusive fitness. The male prairie dogs, in the meanwhile, sit on the burrow rim and give warning barks to help others escape from predators. He, by giving these alarm signals, would not only increase his inclusive fitness (helping the females and offspring be alarmed and escape), but may also receive a reciprocal favor by others later in the future. This can be explained by another theory found by Trivers (1971) known as Reciprocal Altruism. Reciprocal altruism is the process by which an individual will perform an altruistic act towards another in exchange for the second individual returning the altruistic favor some time in the future. The end result of this exchange leaves both individuals with an increased personal fitness. Wilkinson (1984) observed altruism performed between Vampire bats. They regurgitated food for one another in hoping to build up a relationship based on mutual exchanges of favor. If ever a bat would not return a favor, the cost of being denied a meal having once cheated is very high. Trivers was aware of the possibilities, hence he indicated that reciprocal altruism would only evolve in species where individuals could recognize each other and apply punishments to those who refuse to reciprocate. The tit for tat strategy (Axelrod and Hamilton, 1981) works by each animal responding so that a cooperative behavior is followed by a cooperative behavior, and a defection is followed equally by mutual defection, as happens among bats. Sentry meerkats risks attack by giving alarm calls to others. This act will cost danger in his part, perhaps even death; however, it is assumed that the act will be reciprocated in the future. Young male baboons without mates will work together to steal a dominant males mate (Packer 1977): one baboon distracting the dominant male while the other mates. The cost to the baboon (the risk of being injured by the dominant male) is far outweighed by the genetic benefit gained by the baboon mating. However, later on, when the male, which carried out the previous altruistic act, is ready, the second baboon will return the favor by being the distraction. Mutualism, or return effects, occurs where individuals will cooperate and help one another because as a team, they can achieve more than working alone. Caraco and Wolf (1975) observed a mutual effect between lionesses; they hunt together to bring down wildebeests. Induced altruism- also referred to manipulation or social parasitism-is the act of asking for help from others and utilize it as a tactic aimed at cheating. Brood Parasitism, the laying of eggs in another birds nest, is an example of induced altruism performed by cuckoos and a number of other species (Davies and Brooke 1991). Beetle grub begs for food from the passing ant and then preys on them. Aspidontus, a fish whose appearance resembles the cleaner fish Labroides, instead of cleaning the host fish, approaches and bites into its flesh. Charles Darwin was aware that his theory of evolution contained flaws; he did not manage to understand the reasons why altruism occurred; why an individual would carry out a certain act or behavior to help others while, in the meantime, disadvantaging themselves. However, with the help from Hamilton, Trivers, Wilkinson and other researchers, we can now apply the knowledge of genetics that we possess today, and, to a certain extent, explain and justify the reasons of altruism. Research has indicated that for apparent altruism to occur, there must be something in return; compensations such as a genetic reward (increasing their inclusive fitness, key: Kin Altruism), or a long-term reward for the individual involved (personal fitness or self-interest, key: Reciprocal Altruism). But do animals always require something in return in order for them to act out a good deed? Well, there are instances in which true altruism occurs, but it is merely on a non-voluntary or mistaken basis due to som e kind of deception or manipulation (Induced Altruism) but other than that, we can pretty much assume that animals are down right selfish.
