The Course of Human Evolution Essay - 1675 Words

Human life histories are understood to consist of different levels of factors that contribute to the variation and evolution of human health, and this can be analyzed by categorizing the various lifetime events on a fast-slow continuum (Promislow Harvey, 1990 as cited in Kaplan, Lancaster, Robson, 2003). Mammals, for example, are located on the fast end of the continuum and are known to reproduce early, have a shorter period of pregnancy, grow into smaller body sizes, and produce a great amount of offspring that are vulnerable to death. On the other hand, species scattered on the other end of the continuum tend to have characteristic that are opposite to those of mammals (Kaplan et al., 2003). These changing momentums are generally†¦show more content†¦How has human health history progressed? In order to understand the momentum of human evolution, we have to look at that evolution from several different perspectives. Kaplan et al. (2003) proposed an â€Å"embodied capital theory† which suggests that there has been an integration of life history and investment in economics that forms the building blocks of somatic appearance. This theory purports to explain the development and maintenance of human health. The â€Å"embodied capital† refers to the physical organization of the human body and the functions of the various internal organs (Kaplan et al., 2003). This â€Å"capital† provides solutions to problems that may not have been addressed or completely understood. For example, the human brain is one type of embodied capital that supports the ability to learn new information even after adulthood has been reached, notwithstanding the fact that in adulthood the brain has reached its peak mass (Kaplan et al., 2003). Nonetheless, due to the tendency of devaluation in such embodied capital, there seems to be some costs and benefits throughout one’s lifetime. For example, there may be a reduction in the brain system and cognitive perception early in life that results in incompetence of human infants (Kaplan et al., 2003). On the other hand, in a circumstance where there is little information to absorb, the humanShow MoreRelatedThe Course Of Human Evolution1676 Words   |  7 PagesThe course of human evolution can be represented by subsequent development of: 1.

Highway Administrator Paper Free Essays

The administrator of the highway department was given a task to find a way to fill more potholes. This program to fill more potholes would decrease the number of complaints in the city and the number of damages to the residents’ cars. To do this, the Highway Administrator implemented a goal-setting program, in hopes this would encourage the workers to fill more potholes. We will write a custom essay sample on Highway Administrator Paper or any similar topic only for you Order Now This program sets a standard for each crew to fill a certain amount of potholes per day, no matter the location of where the crew was working. The results will then be posted for all of the crews to observe and compare. As an incentive to fill the most potholes possible, the crew who filled the greatest amount of potholes each week was given a reward. I personally believe excellent results will be achieved since the Highway Administrator’s plan follows the design of the goal setting theory. â€Å"Goal setting theory was based on the premise that much human action is purposeful, in that it is directed by conscious goals. † (Neil, 1994) A more updated definition of the Goal Setting Theory states that goals are the remarry drivers of the intensity and persistence of effort. This program is going to be successful since the goals to be met are specific, accompanied by feedback, and difficult, but accepted by the workers. These aspects of the program will increase the overall performance of the workers, meaning more potholes will be filled in the approved manner, therefore, decreasing the number of complaints in the city and damages to the residents’ cars. Since the duties assigned to the workers are meant to help the community, it is safe to say that their Job performance is meaningful. The errors have a clear, spelled out Job description and a list of tasks they need to complete, in the order they need to complete them. With their specific Job description and the workers helping out the community, overall Job satisfaction will rise, increasing Job productivity. â€Å"Meaningful work and Job satisfaction are linked,† (Weir, 2013) and typically lead to overall life satisfaction. Goals set by the highway administrator’s program were specific. The standard set by the highway administrator were that each crew was to fill 20% more potholes than they usually fill on a daily basis. This aspect of the goal is extremely efficient and specific which gives the workers a clear idea of what they need to do at work. If the goal were to simply â€Å"fill more potholes than you normally fill† than each crew could fill one more pothole than they normally do and still meet the goal, but this would probably not complete as much work done as fast as it needs to completed. This goal is also a clear standard because of the different working conditions each crew operates in. Asking each crew to fill five more potholes than normal might prove to be easy for one crew and extremely difficult for another, depending on the conditions. Each crew was also given a step-by-step sheet on how to properly fill each pothole. This will create a filled pothole that will last longer, therefore, making less work for the future. The feedback that accompanies each goal comes at the end of each week. Feedback is objective information about performance. Motivational feedback serves as a reward and the highway administrator clearly understands that since he is using rewards to drive his employees’ productivity. (Hogue, 2004) Each week, the highway administrator will post performance data on a board for all of the other crews to view. Since there are only rewards and no harsh consequences, this creates friendly competition for each crew. The crew who has the most potholes filled at the end of each week wins tickets to a sports game in their locality. Since there is an incentive involved with the weekly performance, the crews will work much harder in order to come first and win the reward. This will drive up the work performance significantly since the reward is something people know they will enjoy. Finally, the goals are official, yet accepted by the workers. It may not be easy at first to fill 20% more potholes than average. Once the crews realize the goals are difficult, yet not impossible, the intensity and persistence of the workers will maximize in order to be the best and finish the work as quickly and efficiently as possible. Each crew will work their hardest to fill many potholes as possible. The incentives come into play once again when it comes to the goal being difficult since each crew knows if they work harder, they will achieve more potholes than the other crews. It is also beneficial to he program that performance statistics aren’t posted until the end of the week. If they were to post performance statistics every day, crews with lower performance may feel discouraged if they are not filling the most potholes, leading them to not work as hard as they may feel they don’t have a chance. The highway administrator’s goal setting program is meant to raise productivity and I predict that is exactly what will happen. Since the goal setting program is based off of the goal setting theory, it needs to follow three important aspects to be successful. When the goals are specific, accompanied by feedback, and difficult, but accepted by employees, they increase the performance of the workers. These aspects serve as the primary drivers of the intensity and persistence of effort. â€Å"In order for an organization to be successful they must continuously ensure the satisfaction of their employees. † (Yip, Goldman, Martin, 2009) Taking the goal setting theory into consideration, the ultimate goal is for the goal setting program to be successful. When workers are satisfied with their Job and the work they’ve done, along with possible rewards they may have earned, they will intuition to work harder. This is mainly since work itself has a strong correlation with job satisfaction. If someone is not satisfied with the work they do, they may not want to work as hard or be as productive. Employees that like their work find it easy to work harder and strive for their best. They do this by setting personal goals for themselves, relating to work, and achieving them. Each crew may come up with team and individual strategies in order to employ every effort to fill the most potholes. This program will raise the workers’ productivity by raising the workers’ satisfaction. If I were the highway administrator, I would implement the same program with minor tweaks. Ultimately, I feel that this program will drive workers to increase productivity and fill more potholes. With this result and more potholes filled, complaints from the citizens and damages to their cars’ will decrease immensely. This would improve the overall moral of the city if more potholes were filled. The reward aspect of this program is one of the most important parts. â€Å"A good reward system should foster personal growth and development and keep talented people from leaving† (Grittier, 1998). This program does Just that, which is why I agree with it and how it will affect the workflow. When individuals set goals for themselves as well as try to receive rewards that may be awarded to them, they grow as a person and do not want to leave due to Job satisfaction and potential rewards. This leads to affective commitment by the workers. Workers will stay with the organization because they want to, not because they feel obligated or need to due to their financial situation. The only aspect I would change about this program is the percentage of potholes that need to be filled. I would survey each crews work area and give them team goals to meet. Anything above that would be compared to the other teams and the crew who was most effective would receive the reward. Overall, the highway administrator’s goal setting program will work effectively and serve it’s purpose of filling more potholes to construct a better community environment.

Rock History Essay free essay sample

The song l Want to Conquer the World comes from the Bad Religion album called No Control, it was written and also released in nineteen eighty nine by Epitaph Records and is a great example of lattice expression while actually conveying how the writer Brett Jerkewitz (guitarist) desires people to seek for peace, not violence. The main theme of the song explains the tragedies of the world in which we live; from hypocritical Christians to soldiers that are ruining peoples homes on a massive scale, then, in the hook Jerkewitz proclaims his intentions Of what he wants to do in order to make the world a better place.It can also be argued that much of the song is anti-religious mostly based off of the bands name which is actually a common misconception. The band members claim to not be in accordance with any specific religion and more specifically Brett Jerkewitz considers himself a provisional diets, which is the belief system of reason and observation of the natural world are a sufficient way of deciding if god is actually fact or fiction. We will write a custom essay sample on Rock History Essay or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The lyrics of the song reflect the time period of about the past twenty years or so when people were beginning to really notice lies from institutions including government. The lyrics of this song are mostly consistent with deep adaptors in order to explain what it is that outraged Jerkewitz. The song is comprised of a lot of natural delivery and shifts to shouting during the hook most likely so as to give emphasis to the central idea of the writers passion to fix world problems.Two of the lyric numbers that have a great metaphor is number five and six; which asks the question does science and all of its effects actually benefit people or is it just making things worse instead? Which in all honesty has a great point since even trying to save the planet room pollution and other harmful mediums actually creates more of the same problems in turn. The lyrics of the song greatly coincide with the musical genre to a certain extent. Most of punk rock is based on what makes the writer angry and expresses the passion for what it is that has caused this internal moral dilemma to be so strong.While the lyrics do not necessarily contain any aggression or anger it explicitly has reasons of what created the outrage and the passion to show the writers desire of how to solve the problems. Although violence is absent from the desire of the artist while writing the song, it still has the basis of punk rock in the lyrics as well as the instruments. Most other analyses for the most part go along with my interpretation, but some of the translations differ from my own completely.While not everyone that has put their two cents in has the same thoughts of the meaning of the lyrics, many of their opinions although still being debatable contain a lot of truth and hard facts that justify their understanding. In most part I would say that a lot of the people that enjoy this song and the rest of the genre like it because of the way it speaks to them personally and connects between their own passions, ideas, and life experiences; I do not believe that people could have the wrong idea about the meaning of the song even if it is not what the writer had intended to portray in his poetry.Most of what I have found for the opinions people have on the song talk about the song as an ironic metaphor about how so many people want to unique the world, which in itself is also a strong metaphor, which is about improving the world according to a threa d posted on a song meanings website.
