Genus Gallioto essays

Genus Gallioto essays The definition of evolution is a genetic change in a population or species over generations. This is exactly what occurred in the case of genus Gallotia in the Canary Islands. The Canary Islands are made up of seven islands, named Lanzarote, Feurteventura, Gran Canaria, Tenerife, Gomera, Palma, and Hierro . Throughout time many changes have happened to the species Gallotia atlantica, found on Lanzarote, to G. stehlini found on Gran Canaria, to G. galloti found on the other four islands. Also, there are many subdivisions found within the species galloti, with one species that appears to have begun to evolve on each of the four islands. The Galloti Genus evolved in the order shown in chart 3. 3. Island Biogeography and Evolution: Solving a Phylogenetic Puzzle by R. P. Filson 4.

The study of Jeffrey Weeks Essay Example | Topics and Well Written Essays - 2000 words

The study of Jeffrey Weeks - Essay Example Jeffrey Weeks has been a well known man for quite some time, and the beginning of this notoriety truly began once his literary works began to come out, as they were more open and more revealing than most others had ever been. His work discusses primarily the issues of homosexuality, however at the same time it discusses much more than that, as he is able to discuss such matters as homosexual identity, finding homosexual identity, the history of homosexual identity, homosexuality in politics, homosexuality and its influence on the world, and much more. He has been both praised and criticized for his work, but overall his work is taken on a most positive note, as it has not only explained and universalized many of the most important issues that are evident in the present day world, but as well it has led to the onset of not only present but future forms of research and contemplation in the areas of his work. In order to better understand Weeks, and in particular that of his contributio ns and his significance to the world overall, we must do several things. First, we must discuss more about Weeks and his life in general, and as well we must then discuss his relevance and how his approach and his contribution to theory building have been influential in general. ... This is what will be dissertated in the following. Jeffery Weeks was born in Rhondda, Wales in 1945, and he was educated at both the University College in London and the University of Kent at Canterbury. In regards to his work he actually basically began as a lecturer in sociology at the University of Kent, and in the year 1980 he became the Simon Senior Fellow at the University of Manchester. He was also professor of social relations at Bristol Polytechnic, continuing his work on throughout this time. Weeks is considered as being "among the academics in the early period of gay men's studies in Britain emerging from the Gay Liberation Front (GLF) which he joined in 1970 and the Gay Left Collective of which he was a founder member. He began by chronicling the development of homosexual politics from the late nineteenth century to the gay liberation movement in Coming Out, (1977)" (The Knitting Circle, 2002). Following his work as a professor at Bristol Polytechnic, he then became Professor of Sociology at South Bank University in the year 1994, and the he was Head of School of Education, Politics and Social Science from 1995-1998, and finally he became Dean of Humanities and Social Science in August, 1998. He spent most of the beginning of his education at select places, as he would stay in one location and then concentrate his work there, and move on once he felt the time was right. Thus he did not scatter from place to place, but rather, as he worked, and as his work became more and more accepted and noted, he basically made his way up the ladder, until he reached where he is today, which he has been at for several years now. Weeks is a man who is incredibly

Organisational Change and Leadership Essay Example | Topics and Well Written Essays - 3750 words

Organisational Change and Leadership - Essay Example Using the example of Property Services Agency privatisation already embarked upon in the United Kingdom, the report will review the issue of organisational change and leadership, while giving a thorough analysis of the agency, conducting empirical research of the problem within the limits of current time period, and in accordance to established legislation. The end of the report will identify the ultimate conclusions on the effectiveness of the privatisation processes for both, the government that has taken the object to its privacy, and for the object of privatisation itself that has either started to perform more successfully, or experienced to meet the downfall in its operational activity. When speaking of organisational change - n important tool in management that is aimed to provide sustainable development and constant growth, - it is worth to mention leadership which is vital quality of manager who is eager to come with the best solution and outcome for the planned change or innovation. Being a private organisation, PSA aims to provide, manage, maintain, and furnish the property used by the government, including defence establishments, offices, courts, research laboratories, training centres and land until restructure and organisational change have come into play and imposed PSA to government's privacy. Within the leadership literature, researchers have sought to identify and describe effective leadership from various perspectives. Universal theories proposed that the same leader traits (e.g., for a review, see Bass, 1990) or behaviors (e.g., Bowers & Seashore) create favorable results in all situations. An inability to consistently predict effectiveness (for a review, see Yukl, 1989) led to the development of situation-contingent theories. Researchers postulated that a leader's effectiveness would be moderated by situational variables that either intensified or decreased the effects of a leader's traits (e.g., Fiedler, 1967) and behaviors (e.g., House, 1971; Vroom & Yetton, 1973). Research testing the utility and predictive value of this real-trait, real-behavior research has produced mixed results ( Yuki, 1989). More recently, an alternative, cognitive-attribution approach has been developed to explain the link between leader performance and perceptual processes ( Lord & Maher, 1990). Research suggests that leadership perceptions, indeed, may often be based on both traits ( Lord, De Vader, & Alliger, 1986) and behaviors and events ( Calder, 1977; Meindl & Ehrlich, 1987; Meindl, Ehrlich, & Dukerich, 1985). Rather than attempting to understand a leader's effectiveness in terms of real traits and behaviors, however, this interpretation is based on observers' subjective realities, as described by more general accounts of person perception and information processing ( Lord, 1985) or attribution theory ( Calder, 1977). In other words, leadership is in the eye of the beholder. A leader may assert influence stemming from several different bases of power (e.g., French & Raven, 1959). The success or failure of an influence attempt depends, however, on whether the influence target actually accords such power to the leader. Without follower responsiveness, leader power is meaningless. The specific relationship between

View of Class Essay Example for Free

View of Class Essay Karl Marx’s view of class as exposed in his Communist Manifesto suggests firstly the existence of two distinct classes with irreconcilable differences. These are the proletarian and the bourgeoisie. The proletarian or proletariat was initially a derogatory term used for people who had no other wealth aside from their children. Marx’s sociological take on the term refers it to the working class. True to its derogatory origin, the proletariat is the class in society that does not own the means of production (Martin, 1998). In short, they are those who are employed to do work and get paid by salaries. The bourgeoisie or capitalist is a term to connote the owning class. They are considered the upper class of society who owns the means of production. They are the merchants, landowners, and other capitalists. Marx’s theory in class revolves around the interactions between the proletariat and the bourgeoisie and the inevitable consequences thereof. Marx argued that the bourgeoisie constantly exploits the proletariat. Since the workers do not own any means of production like their own farm or business, they must seek employment from the bourgeoisie in order to survive. They are hired by capitalists to work on making goods or providing services. These fruits of production then become the property of the capitalist, who sells them and gets a certain amount of money in exchange. Some of the money earned from the selling of the products or services is used to pay the workers wages, while the rest called surplus value is used to pay for other expenses of the capitalist and his profits. This gives the capitalist the ability to earn money out of work done by his employees with very minimal effort on his part (Martin, 1998). Since obviously, new wealth or profit was created through work done by the employees; the capitalist gained wealth or an excess of wealth which he did not work for. If that happened, then that means that other people, that is the laborers did not receive the full wealth which they should be receiving as just compensation for the work they did. In other words, the workers were exploited by the capitalists. On the other hand, Scott and Leonhardt (2005) argued that society cannot actually have the distinct perception of classes that is proposed in Marxist doctrine. They base this on the fact that people regardless of race or social stature are experiencing luxuries that were not as equally distributed just a few decades ago. Marxist principle usually claimed that the normal, everyday worker is of an inferior class to the capitalist. This principle was based on external markers that connote poverty in one and wealth in the other. Scott and Leonhardt’s article makes an attack on the markers of such a principle, arguing that at present, it has become very difficult to know a person’s class from the color of his skin or the gods they worship, much less on the clothes they wear or whether they’re employed or are running heir own business. However, the article itself does not belittle the concept of distinct classes and in fact moves on to argue that class is actually still a very powerful factor in society. What the article simply argues is that this difference in classes can no longer be seen in Marx’s idea of proletariat – bourgeoisie dynamics but has transferred to other aspects such as meritocracy, where a man who starts out poor can actually strike it rich if he had what it takes. It is my stand to agree with Scott and Leonhardt that the concept of class has shifted into from hereditary wealth to the idea of meritocracy. On the first level of argumentation, I say that the assumption of untouchability of the upper class no longer applies today, where big companies such as Enron can be brought to its knees by the public and where several big business tycoons such as Bernard Ebbers of Worldcom can actually be put behind bars for a good long time. This means that both worker and capitalist stand on equal footing where the law is concerned which implies that the supposed unfair, overwhelming power that big companies hold over its employees has been reduced to a memory. On the second level of argumentation, I believe that meritocracy has transcended barriers between countries and provided an avenue by which worth is determined by what a person can do rather than what his heritage is. The first support to this is the advent of public corporations. These entities build an administrative base that is dependent on meritocracy. A public corporation is owned by all the people who invest in it which can be considered as capitalists, but the top notch directors that they hire don’t need to be stockholders, nor do these executives get hired because they are relatives of the shareholders. More so they get hired because their credentials, from educational background to previous work experiences, says that they can get the job done better than anyone who has money in the company, and that if they should be handsomely compensated if they are expected to work for that particular company. The top CEOs’ incomes usually surpass the lot of a public corporation’s investors. I disagree with Marx’s portrayal of class and class struggle on two levels. The first level is that workers have at present various protections against exploitation by their employers. Labor unions lobby for progressive compensation based on the company’s own profits. This means that laborers today are actually getting their wages based on their company’s progress. The more profits they bring in, the better leverage their union has in negotiating wage increases. On the second level, even today’s capitalists recognize the importance of obtaining and maintaining an efficient labor force. Corporations consistently compete for worker bases in the country and abroad, trying to outdo each other with better benefits, more convenient working conditions, and higher salaries. This indicates that the capitalist can no longer be viewed as the laborers’ enemy. Rather, quality labor itself has become the product of laborers that makes them capitalists in their own right, since the demand for quality labor has become so that capitalists are willing to purchase their labor at their price. In conclusion, class is a concept that has evolved through the years. Situations that may have been applicable during Marx’s time may no longer be effectively used to describe what is apparent in today’s economic world. We must reflect on the value of labor today and see our own worth that for us to market, making us all equitably equipped for life’s challenges ahead. Sources: Martin, Malia. (1998).

Love in “A Midsummer Nights Dream” Essay

In Shakespeare’s â€Å"a Midsummer Nights Dream† love is shown in many different ways. During the play there are many different sub-stories and extra plots that it is easy for Shakespeare to add many different ideas, these sub-stories in the play are the story of Pyrimus & Thisbee and also the story of the Fairy King and Queen Oberon and Titania. With these added plots in place Shakespeare adds the themes of deceit, magic and confusion. In Act 1 Scene 1 parental love is shown when Hermia’s father Egeus tries to get his daughter to marry Demetrius who he believes is much better for Hermia than her true love Lysander. Egeus believes he is protecting his daughter by attempting to force her to marry Demetrius but is actually going against his daughters wishes as she wants to marry Lysander, Egeus then presents her with an ultimatum which makes her choose to marry Demetrius of live a Celibate life in the church and it is at this point in the play that Hermia and Lysander choose to runaway. This is a good example of parental love going terribly wrong as Egeus loses control over his daughter when she deceives him by running away with the man her father disapproves of her marrying, this also starts of the plot of the confused lovers. Shakespeare portrays the confusion between Hermia, Lysander, Helena and Demetrius by using the fairies and the ideas of dreams and magic so the reader cannot tell what is reality and what is fantasy. It is at this point in the play when the fairies are brought into the play as the mischievous ‘Puck’ causes mayhem between the four Athenians. The confusion is caused when Oberon sees Helena constantly doting over Demetrius despite Demetrius’s love for Hermia, he then sends Puck to fetch a magical flower to put on the eyes of Demetrius so that he would wake and set eyes on Helena and fall in love with her, but this all goes wrong when he places the flower on Lysander’s eyes and he is woken by Helena, consequently falling in love with Helena and snubbing Hermia. The confusion thickens further as Puck then also applies the magical flower to Demetrius and he also falls in love with Helena and results in Lysander and Demetrius fighting over Helena. This keeps the r eaders interest because of the sudden role reversal between Hermia and Helena. The Confused Lovers is written into the play well into the play very well and effectively and by portraying it using fantasy and  magic Shakespeare is able to add another dimension to the play. By bringing magic into the play Shakespeare introduces the deceitful element to the love and also a higher level magical degree. The story of Oberon and Titania is one of Male Dominance, Jealousy and Conflict. Titania and Oberon are king and queen of the fairies and there relationship affects the goings on of nature. Titania’s part in the play is highly unpredictable as she shows love for 3 different characters; these characters are Oberon, Nick Bottom, and The changeling child. These are three different types of love, her love for Oberon seems forced and full of conflict, her love for Nick Bottom is due to the same magic as used on the confused lovers and her love for the Changeling Child is out of care and consideration as she has rescued it. The changeling child sparks the argument between Oberon and Titania and this leads to Titania’s abrupt love for Nick Bottom. This is planned by Oberon as revenge for Titania not giving him the changeling child as a servant. Titania’s love for Bottom is only due to magic and many other aspects, one of these aspects is Titania’s love of being in love and the love for bottom is very wrong. It is wrong as he is an innocent victim of Oberon and Puck’s trouble making and cannot do anything to stop what has happened and Titania takes advantage of this using her beauty and the luxurious treatment he gives him to get what she wants while he believes it is a dream, we realise this as he isn’t sure where he is or what happened to him. There is love between Hermia and Lysander and also Demetrius and Helena either side of the confusion when the four venture into the forest. The love between Lysander and Hermia is very true and exists from Lysander to Hermia and vice versa. This is displayed very early on in the play when Lysander refuses to give up on Hermia when her father demands she marry Demetrius and also when Hermia is willing to run away from a life of spoils and riches just to be with Lysander. This love is still the same at the end as neither Hermia nor Lysander have any memory of what happened due to magic yet again. On the other hand the love between Demetrius & Helena is forever changing up until the end of the play, at the start Helena’s love for Demetrius is doting and obsessive but Demetrius returns none of this love. This is well  shown when they are in the forest and Helena says â€Å"the more thy object me the more I dote on you† she continues to make comments like this even when Demetrius continually rejects her, it is obvious he dislikes Helena as he makes comments such as â€Å"I love thee not, therefore pursue me not† this makes it obvious to Helena that Demetrius dislikes her but she still pursues him right up until the end of the play when he finally falls in love with her. Although once more this love is only due to the magical works of Puck. The problems between Hermia and her father are resolved when the four now unconfused lovers are found by Theseus and Egeus in the forest, Theseus then heard of there love for each other and declared â€Å"fair lovers you are fortunately met† and all happiness is achieved. The four lovers have no memory of the events that have happened and think it is all a dream but it is actually reality. Shakespeare uses a variation of techniques and themes to portray love in â€Å"A Midsummer Nights Dream†. Many are successful but the sub plot of Pyramus and Thisbee is unsuccessful as it does not play a major part in the play and the reader knows that the happenings of the play are not reality but with the other themes the reader does not know whether the happenings were reality or not. The other themes are successful because of the fact that there is no differentiating between reality and dreams, I think Shakespeare is successful in portraying love in the play and I also believe that his extensive use of various themes is a key to this success.
