The Evolutionary Arms Race - Natural Selection

The Evolutionary Arms Race - Natural Selection Species, in order to evolve, must accumulate adaptations that are favorable for the environment in which they live. These preferred traits are what make an individual more fit and able to live long enough to reproduce. Since ​natural selection chooses these favorable characteristics, they get passed down to the next generation. Other individuals that do not exhibit those traits die out and, eventually, their genes are no longer available in the gene pool. As these species evolve, other species that are in close symbiotic relationships with those species must also evolve. This is called co-evolution and it is often compared to an evolutionary form of an arms race. As one species evolves, the other species it interacts with must also evolve or they may go extinct. Symmetrical Arms Race In the case of a symmetrical arms race in evolution, the co-evolving species are changing in the same way. Usually, a symmetrical arms race is a result of competition over a resource in an area that is limited. For example, the roots of some plants will grow deeper than others to obtain water. As the water level goes down, only the plants with the longer roots will survive. Plants with shorter roots will be forced to adapt by growing longer roots, or they will die. The competing plants will keep evolving longer and longer roots, trying to outperform each other and get the water. Asymmetrical Arms Race As the name implies, an asymmetrical arms race will result in the species to adapt in different ways. This type of evolutionary arms race still results in the co-evolution of the species. Most asymmetrical arms races come from a predator-prey relationship of some sort. For instance, in the predator-prey relationship of lions and zebras, the result is an asymmetrical arms race. The zebras become faster and stronger to escape the lions. That means the lions need to become stealthier and better hunters in order to keep eating zebras. The two species are not evolving the same types of traits, but if one evolves, it creates the need in the other species to also evolve in order to survive. Evolutionary Arms Races and Disease Humans are not immune to the evolutionary arms race. In fact, the human species is accumulating adaptations constantly to fight disease. The host-parasite relationship is a good example of an evolutionary arms race that can include humans. As parasites invade the human body, the human immune system will kick in to try to eliminate the parasite. Therefore, the parasite must have a good defense mechanism to be able to stay in the human without being killed off or expelled. As the parasite adapts and evolves, the human immune system must adapt and evolve as well. Similarly, the phenomenon of antibiotic resistance in bacteria is also a type of evolutionary arms race. Doctors often prescribe antibiotics for patients that have a bacterial infection in hopes that the antibiotics will stimulate the immune system and kill off the disease-causing pathogen. Over time and repeated uses of antibiotics, only bacteria that have evolved to be immune to the antibiotics will survive and the antibiotics will no longer be effective in killing off the bacteria. At that point, another treatment will be necessary and force the human to either co-evolve to fight off the stronger bacteria, or find a new cure to which the bacteria are not immune. This is the reason why it is important for doctors not to overprescribe antibiotics every time a patient is sick.

Case Analysis Part IV - Lab Report Example Therefore, nondelivery of the certificate does not intervene in any way with passing the title. The same conclusion has been reached by the Court in the case of Wood Chevrolet Co. v. Bank of the Southeast3, where it was held that: â€Å"†¦non-delivery of a certificate of title at the time of a sale does not prevent the passage of title from the seller to the buyer.... This is true even where a state's certificate of title act provides that no title can be acquired in an automobile until the certificate of title has been issued.†. In conclusion, title to the car passed to Mann at the moment of physical possesion of the car being transferred to him. CHAPTER 17 CASE 3 I believe that in this case, Frank’s Nursery & Crafts, Inc. must be held liable for the damages caused to Young and it should certainly cover the damages caused to the plaintiff. Frank’s Nursery & Crafts, Inc. has certainly breached the contract concluded with Young. Due to the fact that Frankâ₠¬â„¢s Nursery & Crafts, Inc. ... v. Johnson4, the Court held that, in order to avoid the injured party not recovering her losses, â€Å"Ohio law allows a damaged lost volume seller to recover its lost profits from the breached sale in addition to traditional breach of contract damages†, thus applying the lost volume seller theory. According to Goldberg, V.P., â€Å" In cases in which the seller is a retailer, the conclusion is (a) yes, the seller does suffer damages, (b) the damages are the market price of the service of selling the goods, (c) the market price of selling is approximately the gross margin, (d) even though the damages are incurred, full compensation would probably be inefficient, and (e) the law ought to encourage the parties to use nonrefundable deposits as liquidated damages.†5 Therefore, I believe that the Court ought to apply the lost volume seller theory in this case and, thus, reduce Young’s damages to minimum. CHAPTER 18 CASE 6 I strongly believe that the Benfers did have c ause of action against the retailer – Thomas, along with the manufacturer - Town & Country Mobile Homes, Inc. Thomas was the one who actually convinced the Benfers, by showing them a model mobile home, that the mobile home had the one-quarter-inch sheathing on the siding that made it better than cheaper units, by this intentionally misleading the couple and creating for them a misrepresentation on the product they were about to purchase. Moreover, Thomas, by knowingly proposing the Benfers a more expensive unit, which supposedly had the sheathing desired by the potential buyers, actually lied to them, by taking the price for a more expensive product and offering them a cheaper one. Moreover, by delivering to the purchasers the written warranty, which stated that the mobile home had the

Fertility Pattern and Economic Struggle Research Paper

Fertility Pattern and Economic Struggle - Research Paper Example Feminism is a very important concept that must be thrown light upon when gender conflict is being talked about. Feminist aims at providing women more power and more rights than ever seen before. There are several feminists fighting for the rights of women all across the globe. Respect is also another important factor for which the feminists are consistently fighting. Gender conflict has made us understand how people enjoy preferential treatment and how the inferior strive for parity in the society. Race conflict is also quite similar to gender conflict, some people consider that their race is superior and others are inferior to them, this is certainly beyond the pale. Having a level playing field in the society is essential to facilitate growth; an ideal society always provides a level playing field. â€Å"Rae Lesser Blumberg developed a theory emphasizing women’s degree of control of the means of production and the distribution of economic surplus.† (Blumberg) Blumberg ’s aimed at explaining the position of women relative to men in almost all types of societies. These societies included the earliest societies to the late twentieth century. This theory discussed some really important aspects like economic power of women, importance of women in the society, economic power of women in the society, sexual stratification so on and so forth. â€Å"Sexual stratification, Blumberg argues, is ultimately driven by the degree to which, relative to men, women control the means of production and the allocation of productive surplus or, in Marxian terms, â€Å"surplus value.† Such control gives women  economic power  that, in turn, influences their level of political power, prestige, and other stratifying resources. In Blumberg’s view, sexual inequalities are â€Å"nested† at diverse levels: Male-female relations are nested in households; households are nested in local communities; and if a society is sufficiently large to revea l a coercive state and a system of class stratification, household and community are nested inside of the class structure that, in turn, is lodged within a larger state-managed society. This nesting is important because women’s control of economic resources can be located at different levels, and the level at which their economic power is strongest influences the power that women can command at the other levels of social organization.† (Feminist Conflict Theory) Macro level control and micro level control are some important aspects which must be paid attention to. A woman is ought to enjoy power in a household if she contributes immensely to the income of a household, she will have a say in micro aspects of the household as well if she can contribute towards work and family income. Similarly a woman who is not able to earn and contribute towards the household income will not enjoy as much freedom and control as a woman who can earn and support her family. Financial free dom is extremely important for a woman to be considered powerful enough; only a powerful woman can make decisions and can stand against oppression. Economic power at a macro level facilitates women in getting political as well as coercive power in the society. The economic power of women is consistently on the rise; this is the time of transition. This period of transition is perceived as a major threat by men.

Issues Faced by Honda Essay Example for Free

Issues Faced by Honda Essay The 3 issues that are faced by Honda is the conflict between Toyota. Honda is the 1st company developed hybrid not the Toyota but by stubbornly sticking to a bare-bones system, it long a go lost its leadership to its number one Japanese rival. Honda is suffering at the very moment when its two main Japanese rivals are thriving. Toyota is getting a jolt of energy from Aiko Toyoda, scion of the founding family, while the ever-energetic Carlos Ghosn has made Nissan the leader in electric cars. Which perhaps illustrates another part of Honda’s problem is Honda is lack of genius and they need to find more engineers to help them figure out the new model or engine to solve the problem. Second the issue that faced by Honda is supply resources from other country. Honda do needs supplyment resources from other country such as Thailand, Japan and so on. Due to the Japanese earthquake and tsunami and flooding in Thailand, it had made Honda lack of resources to do their accesoory and requirement from engine. This make their enemy company such as Nissan, Toyota, BMW to have a chance to sell more cars compare to Honda. Honda do needs to wait for the supplier to give them the resources hence make the sales from honda drop. Lastly the issue that faced by Honda is Honda lack of funds. They did not go and find other company to help them. Honda has spent months struggling with shortages of most of its products- nortably including the all-new Civic it launched earlier in the year, just before a devastating earthquake and tsunami struck Japan and seriously damaged that nation’s automative infrastructure. It will be very difficult for Honda to make the sales increase.

Comparing two openings of Lord of the flies and Great expectations Essay

It is important that the opening of a book should be able to entice the reader to carry on and pursue the reader to finish the book through and an exciting or a mysterious opening that will encourage the reader to find out what would happen next. I find that Charles Dickens’ opening for â€Å"Great Expectations† had to be exciting and dramatic because he sold his chapters in weekly issued ‘magazines’ which meant that if the opening issue wasn’t exciting enough for the reader, he or she would not buy any more issues of Dickens’. In ‘Great Expectations’, we are introduced to the main character Pip. This is because the story is told in the first person. We are ‘semi-introduced’ to the convict halfway through the chapter. I feel that Dickens makes the child (Pip) believable by showing his innocence through his speech and dialogue; â€Å"Also Georgina†¦Ã¢â‚¬  I feel that this quote shows he’s not old enough not to add the word â€Å"also† in front of a name on a gravestone. Another good example of making Pip more believable is when he describes the appearance of the convict; â€Å"†¦soaked in water, and smothered in mud, and lamed by stones†¦Ã¢â‚¬  The repetition of the word â€Å"and† makes the speech more familiar to what a child would say when he or she gets excited or scared of something. Dickens also makes the convict believable by the use of dialect, appearance and actions he makes the convict use during his encounter with Pip at the graveyard. â€Å"Give it mouth!† this quote shows that the dialogue is quite authentic or colloquial. Dickens also shows how the convict frightens Pip as he â€Å"tilted† him lower until he â€Å"looked most powerfully down into mine†¦Ã¢â‚¬  This could create fear for Pip and also invites the audience to feel sorry for Pip and hopefully wanting to know what happens next. The convict’s appearance is quite detailed and quite believable; â€Å"†¦all in coarse gray, with a great iron on his leg. A man with no hat, and with broken shoes, and with an old rag tied round his head.† This quote shows that from his clothes and the â€Å"great iron† on his leg, it is quite clear that the convict has escaped from prison with difficulty coming across the plains. The convict’s actions are also portrayed quite well from the â€Å"dip and roll† to hugging his â€Å"shuddered body†. It shows that although the convict is very fearful to Pip, I think that there is a more ‘softer’ side to the convict due to the way as he tried to â€Å"hold himself together† by â€Å"clasping himself†. In ‘Lord of the Flies’, we are introduce to the to mostly the entire large cast that is on the island like Ralph, Jack and Piggy. Dickens’ shows Ralph through mostly his actions like when he â€Å"stood on his head and grinned† at Piggy or when he â€Å"jerked his stockings†. These actions show he is very adventurous but at the same time is very decent because during that time, pupils were made to pull their stockings up if they fell down in school. Although he is not in School, I think it is an automatic ‘habit’ that Ralph pulls up his stockings. Golding describes Piggy through his speech and dialogue; â€Å"All them other kids† This is a good example of why Piggy doesn’t fit in on the island. It shows he is a lower class to everybody else due to his grammatical mistakes in his speeches and conversations. His appearance is probably the first reason why he finds life on the island difficult; â€Å"He was shorter than the fair boy and very fat†¦and then looked up through his spectacles† The glasses and his weight shows him at a disadvantage because he is unable to do anything active when the boys start to play. Also, he has asthma which nearly makes him ‘immobile’ other wise if he does active things, he could start suffering because he would be out of breath or his glasses would break leaving him nearly ‘blind’ for they rest of their stay. Golding puts Jack across to the readers by using his dialogue and appearance. From Jack’s dialogue, it shows that he is very commanding and should have been the natural leader; â€Å"Choir! Stand still!† This shows although they are miles away from home, Jack is still able to control his choir. His appearance makes him look quite evil during the beginning of the story. He had â€Å"red hair† and wore a black coat with a silver cross on the left breast†. The red hair could show that he had a fiery temper like when he found out there was no â€Å"man† on the island; â€Å"†¦ frustrated now, and turning, or ready to turn, to anger.† The choir, who were all dressed in black, from a distance they were described as â€Å"something dark† and â€Å"the creature† The colours used were black and red, which could be linked with evil and anger. Images and setting are used to make the author’s idea stronger or to think things in their point of view. The ‘Great Expectations’ setting shows its secluded shows it’s secluded, dark and cold; â€Å"†¦and that dark flat wilderness beyond the churchyard, intersected with dykes and mounds and gates†¦ was the marshes.† I think Dickens sets the first setting in a dark churchyard because the reader would start to wonder why a small boy is doing in a dark churchyard and would try to find out what happens next. The setting is also made vivid by the way Dickens adds features to the countryside like â€Å"beacons† or â€Å"batteries† which connect with war and death making the place too dangerous for Pip to be there. There is a dark atmosphere created in the opening because Dickens wants to give the audience an exciting opening, which will interest his audience. The setting in ‘Lord of the Flies’ is completely different to ‘Great Expectations’. It is set on a tropical island where places like the lagoon show that it is a place, which could be safe for children to swim and play in for example. The island is made into a kind of paradise that could be similar to the Garden of Eden where in the beginning it was perfect but human presence made the Garden worse. Although quotes show the island is a paradise, there is still an element of evil on the island with the â€Å"witch-like cry†. The atmosphere in this opening is completely different. I feel that there is a more ‘celebratory’ atmosphere created here because there are no parents to supervise them and they could do anything they want. Also, they are away from any signs of war or conflict with another country because this story was set during the Cold war. Although there are signs when the atmosphere will change like when Ralph becomes the surprise leader when it should have naturally gone to Jack. We are able to sense a bit of Jack’s anger; â€Å"†¦ and the freckles on Jack’s face disappeared under a blush of mortification† Golding shows this is not another adventure story because of differences on the island where Jack, the obvious choice for leader, wasn’t chosen to be the leader but Ralph was. Disagreements could lead from Jack modifying Ralph’s rules and creating his own group or ‘tribe’: the â€Å"Hunters†. Dickens also doesn’t give away the plot but it is possible that Pip will find himself in trouble after stealing the food and the file. I felt that ‘Lord of the Flies’ has succeeded in persuading me to carry on reading it because of the way it is able to combine good characters with a good setting. I also find that it is able to give the story on two levels, in a literal story level and also a moral level showing us an examination of evil within human nature in the form of the small group of little boys. I also found ‘Great Expectations’ has also succeeded in persuading me to read on because of good characters and vivid descriptions of actions. There is also a slight sense of humour added to the story as well.

HR Roles and Responsibilities Essay

Human Resource is a field that has attained reasonable and due attention by many leading firms in recent times. Human Resource has been recognized as an important factor for achieving success in the global arena and in gaining a competitive advantage in the industry. Many leading firms put special importance on the behavior of their work force playing an important role in the success of the organization. To maintain this they have planned and organized their human resource function in such a manner that it provides them a competitive advantage in the industry they operate. If we talk about Human Resource Management which has been a dedicated field for improving Human Resource function of any organization puts special emphasis on certain important aspects to be taken care of regarding the employee to achieve success in formulating a successful Human Resource department. These factors are the compensation plans and strategies, Reward and incentives plan, Training and trainability of the employees, Hiring and Recruiting and Future or career development plans (Mathis and Jackson, 2007). All these factors play a strong role and go side by side in the formulation of a competitive Human Resource Department. Human Resource has recently achieved a huge amount of success due to the realization of its importance in the organizational environment. It has been identified as a competitive advantage by some of the organizations due to the importance of Human Resource in the related industry. Human Resource Management has also changed its shape according to the trends in the World and the factors that drive change. These factors include Globalization, Technology, Diversity, and Ethics. All these factors go side by side as the business spreads due to these factors (Dessler, 2007). Globalization has been due to the technological advancements and because of which diversity increases and more ethics related situations arise in an organization. The work of human resource at one hand increases due to globalization, diversity and ethics but on the other hand Technology helps them to resolve these issues. There have been recent trends of using more and more technological equipment in the Human Resource processes. The major work of the Human Resource is to provide the organization with quality people that become the work force of the organization. In this paper we would concentrate on two functions of the Human Resource Department and how they have changed according to the trends of the human society and development of Humans. First we would discuss induction which is a very common practice in the current scenario of any organization. Induction is basically the first step in which an employee gets to know about his or her workplace environment. This covers each and every activity that helps the employee in adapting to the environment and people around him at his or her workplace. Induction can also be termed as the process of building a relationship between the employee and the organization the nature of this relationship is of a two way communication process (French, 2006). Starting on a new position and with a new organization can be a process which might take some time for the employee and the organization to get settled with. There are many new things that need to be understood and get familiar with these include fellow employees, supervisors and managers to interact, entirely new processes that need to be understood and followed, new offices and buildings that are required to be navigated, learning to work on new software, new and unknown employment environment to understand and new tasks to learn. This transition or all the above mentioned activities are made easier and more effective for the new employee as well as for the employer if the induction schemes in the organization are effective and efficient (Mathis and Jackson 2007). There are obviously costs for implementing effective and efficient induction schemes but the benefits are more far reaching and long lasting if a comparison of both costs and benefits are made. Induction is a process that has been recently added in the organizational hiring and recruiting process by the Human Resource function. There was no concept of induction some 15 to 20 years back. As organizations tend to realize the importance of working environment, which factors affect the performance of an employee and the importance of organizational culture induction has been the solution or the bridge to reduce the gap between an employee and its surroundings in a new environment (Ivancevich, 2009). This not only helps the employee in speeding up the level of his performance in the organization but also reduces the time to know different people around the organization. Performance Appraisal is another important task that needs to be completed by the Human Resource Department. This task requires a great amount of analyzing and insight on the work an employee has been doing. The employee performance is not the only criterion that is considered while creating performance appraisals. Other aspects such as employee’s attitude towards his or her job, how he or she behaves with the colleagues and other aspects such as absenteeism and the following of ethics in the work environment are also criteria that need to be studied while making performance appraisals. All this is not an easy task as studying qualitative aspects of an employee and evaluating them becomes a very difficult task to do. Apart from that employee performance can only be evaluated through the direct supervisor or manager who the employee reports to (Mondy, 2007). This can bring in to play the personal feelings and impression of the supervisor or manager under which the employee works and can create biasness in the evaluation process. Apart from this judging behaviors and attitude is another complicated task. Performance Appraisals have now included a great amount of technological tools to be used for helping in this process. Organizations have online forms for employees, which reduces the time to gather data about the performance of an employee and even retrieving it hence helping in quick appraisals and employee satisfaction of his or her performance. Not only it has reduced time but also made the procedure very effective than before helping in the work of the Human Resource Department. To conclude this paper I would like to mention the fact that all the trends and advancements in the field of human resource management have helped the organizations in making the function more effective and efficient. Some organizations proudly say that their Human Resource department is the competitive edge they have in the industry. Especially in the IT industry it is very important to maintain a effective and efficient Human Resource Department due to the fact that it can provide competitive advantage to the organization.
