Seahorse Essay Example | Topics and Well Written Essays - 1000 words

Seahorse - Essay Example Nowadays Hippocampus counts almost 20 species, including Hippocampus ingens (dwelling in Pacific ocean), Hippocampus reidi (longsnout seahorse), Hippcampus erectus (Northern seahorse), Hippocampus kuda (the yeallow seahorse) and many others. "Despite previous taxonomic classifications as insects and amphibians, they are fish, cousins to pipefish and sea dragons, from the family Syngnathidae, Greek for "fused jaws." Like most fish they have gills for breathing, a swimbladder for buoyancy, two pectoral fins for balance, and dorsal fins that flutter as much as 35 times per second" (Arrigoni, 1989, p.358). As one can see at the picture below, seahorses have no teeth, caudal fin for speed and stomach, as the last part is replaced in seahorse morphology by enormous tail, used for great speed development. In spite of their beauty and grace, seahorses serve as the Frankensteins of underwater 'society', as they are apparently made of various animals' body parts. As their name shows, seahorses have vertical body and horse's head, situated perpendicularly to the body. Furthermore, seahorse has a kind of crown on its head, and what is most amazing about this body part is the fact that this coronet is as unique as human DNA (Lourie et al, 1999). In addition, their body armor is quite... Their snout and body armor resemble an aardvark's.In terms of their ability to change coloration, seahorses resemble chameleons, as they also mimicre in accordance with the environment colors. "Also with lizards, they share independently moving eyes, assisting both survival and predation tactics. They've borrowed prehensile tails from monkeys, and made a major alteration to the brood pouch of marsupials, with male seahorses nurturing their young" (Lourie et al, 1999, p.231). (from Long, 1995, p.192) As for the reproduction and prenatal behavior, seahorses are distinguished due to the unusual behavior of male individuals, or so-called mating rituals, which are typically attributed to the animal classes as well as to some fish species. Moreover, male individuals usually carry and accept fertilized eggs to order to extort brood in future, as both females and females have prolactin, the hormone that allows this form of hermaphroditic reproduction (Arrigoni, 1989). "Individuals reach sexual maturity by the next breeding season following birth, at the ripe age of three months to a year, depending on size of the species. Breeding seasons vary by species and may be restricted by cooler weather or monsoons, though some go year-round" (ibid, p.188). In particular, H. ingens is able to breed at 12 months, and it is important to note that couples are monogamous as a rule. During the breeding season, pair bonds are encouraged by daily greetings, when individuals prepare an entire performance for each other: change colors, dance and then promenade together by entwining their tails. Furthermore, the female individual puts its oviopositor into the male's brood pouch in order to transmit

Discussion Topics - Assignment Example If power is centralized, an abusive government can come into existence and misuse the state of security, to cause massive and unreasonable destruction to both the United States and other nations. Divisive power observes control and regulation in decision-making. The American constitutional structure has advantages such as the practice of pragmatism, which is very relevant and applicable to a country as large as the United States of America. The constitutional structure creates laboratories of democracy. There is experimentation of policies and state governments can learn from the successes and failures of other states. It helps set a state of political stability by separating national government from areas of contentious issues. Finally, the constitutional structure helps encourage pluralism i.e. by expanding to local, state and national levels. By separating powers, it prevents tyranny (Beard & William 87). The disadvantages of the constitutional structure include prevention of national policy. It lacks single policy on issues i.e. each state with its own and this causes confusion. It also leads to lack of accountability; the overlap of state and national boundaries makes it hard to assign blame on policies that have failed. To other democracies, the structure of the constitution depends on the geographical and political coverage. Small nations would function well with parliamentary systems, but to fully practice democracy, federalism would be the most effective. Members of the public should be adequately informed on the issues of governance and politics in order to fully practice democracy. This also helps in the monitoring of the activities of the people in authority. Ignorance would definitely reduce the effectiveness of a democratic nation. Most of the Americans, however, are not well equipped with this information to guide the policies of the

Business Ethics Essay Example | Topics and Well Written Essays - 1500 words - 2

Business Ethics - Essay Example Throat cutting competition and desire for growth is pushing companies to make every possible effort to improve their performance. It was during the 1950s when experts used the term â€Å"performance management† to refer to the systematic and controlled process with which organizations would monitor their performance in order to achieve their goals effectively and efficiently. Today, performance management is a crucial part of every big organization. Despite the fact that the Human Resource Departments are usually responsible for conducting the performance management functions and activities, entire organizations contribute to the process to make it successful (Dresner, pp. 214-219). There are five major pillars of performance management. First, planning the goals and objectives and deciding on the expectations. Second, performance management, as mentioned earlier is also about having a check and balance on the performance of the organization and its employees. Third, performan ce management also binds managers to ensure that there are enough resources available at the disposal of the company, departments, and employees to achieve those goals. Fourth, with the help of balance scorecards and performance appraisals forms, performance management also requires managers to rate and evaluate the performance of individuals and groups. Fifth, lastly, with different pay systems of contribution-based pay, performance based pay, skill based pay and others, and it rewards and appreciates employees for their performance (Cardy, Leonard & Newman, pp. 85-89). Managers all over the world are realizing that many decisions and processes required for performance management necessitate upholding of high ethical and moral standards. These ethical dilemmas are everywhere in the system of performance management. It becomes even more important to answer and address because many decisions concerning the future of the company and the future of its employees, remains depended on the se performance management decisions. Companies use this data for recruitment, selection, layoffs, terminations, promotions, bonuses, pay increases, rewards, demotions, and others (Cardy, Leonard, & Newman, pp. 85-89). One ethical question, which comes up during the performance management of companies, is the fact that whenever companies manage performance of their employees, they are well aware of the fact that the element of â€Å"bias† is embedded deeply in the system. Experts have pointed out many forms of bias, which are present in the system when employees are being rated. First, leniency error when the rater or the manager has the tendency to be lenient, nice, and kind to all the employees because he knows that these ratings would probably decide their future. Furthermore, in order to keep harmony within the group or the department, to gain support, to avoid any tensions or confrontations, managers also try to give above average ratings to all the employees. Second, cen tral tendency error occurs when managers do not want to give very high or very low ratings to anyone. Many managers know that their high and low ratings would force employees to ask them a series of questions, explanations and proofs and the best way to avoid that conversation is by giving them all average rating (Luecke, Hall & Harvard Business School, pp. 321-324). Third, halo effect occurs when manag

Regression Analysis Research Paper Example | Topics and Well Written Essays - 1000 words

Regression Analysis - Research Paper Example It is an effective tool of mathematical analysis, which allows estimation and evaluation to the nearest proximity compared to the past. It also allows predicting a certain future value through comparison and combination of two or more variables. Usually, hypotheses are taken up for case estimation and evaluation which involve plotting of various variables dependent on the time factor. Regression models can be both linear and non linear in nature. Response variables are generated by the comparison of numerous variables that are involved in the computational process. Response variable is of quantitative nature and derived as result of other variables tested and compared amongst each other. Regression analysis is used for predicting certain event (mostly the dependent variable), its outcome in terms of numerical percentage and value in combination with other variables (independent) which might be elements of the present time (Seber & Lee, 2012). Equations are derived which contain both the dependent and independent variables, against some constant. Regression analysis equations are linear in nature. The function so obtained is a straight line, in form of linear equation. Often the natures of the dependent variables have direct impact on the kind of final linear equation being yielded. In case of the dependent variable being dichotomous, the logistic form of regression is handy in such cases for evaluation of the linear plots. When multiple independent variables are up against one dependent variable, it constitutes standard linear multiple regression (Hill & Lewicki, 2006). In such cases, the single dependent variable can be compared one on one against the respective independent variable. Numbers of variables are set against each other and each of them affects the other directly. For example in case of stock exchange the stability of and sound running of stocks are dependent on various external factors, which can include the economic condition, the security and saf ety, any major political decisions in the governmental corridors. Any unexpected decisions are ascribed to the rise or fall in the stocks value. In this case, the stock market is one variable which is dependent on number of variables that are aforementioned. Each of these variables, both dependent and independent are plotted against a graph with x-axis representation and y-axis along a straight linear line. Stocks standing = Stable Market, Political decisions, other variables plus a Constant. For any economic factor indication, the variables that can be taken in to account include the net flow of income at a particular instance of time, the dependent variables on the fixed amount, the surplus amount in form of the revenue generated and the possible depreciation of the capital. All these are equated and compared against each other in form of plot to estimate the future trends. Mostly, it involves number of variables being operated upon; however at a particular instance of time when o ne variable is under observation, it constitutes a simple regression analysis scenario. For example in case of an individual’s average spending against his profession, his resources, his requirements, all these alone make for attributes which are evaluated and analyzed for a certain desired future scenario through the regression tool of estimation. If for a given scenario, more number of

Painting Styles, Impressionist, Post-Impressionist & Modern Essay

Painting Styles, Impressionist, Post-Impressionist & Modern - Essay Example The essay "Painting Styles, Impressionist, Post-Impressionist & Modern" explores such painting styles as Impressionist, Post-Impressionist & Modern. The group included the rebellious young Artists looking for new ways for the expression of ideas in painting. They attempted to question the traditionalists by portraying objects and scenes that lacked definition, and tried to explain how the eye interpreted objects. Exponents of ‘Impressionism’ also exploited the light sources for exploration and translation of light on the canvas, and the subject matter was the modern world, particularly landscapes. The founding members of ‘Impressionism’ were Claude Monet, Edgar Degas and Camille Pissarro."Images of suburban and rural leisure outside of Paris were a popular subject for the Impressionists.† The artistic technique of ‘Impressionism’ includes strong strokes of brush on canvas, and this style uses vibrant shades and attempts to translate scenes with mood and feeling. The Painting-â€Å"Autumn Evening,† by the Russian Painter Oleg Frolov in the year 2001, an oil painting on canvas, can be considered as an example of typical ‘Impressionist Painting.’ Post-Impressionism: Post-Impressionism is less easy to define and it differs from Impressionists on dissimilarity in personal styles, and subjects. In the transitory effects of light and spontaneous compositions, they share similar interest with Impressionists and concern with light, but their personal styles vary greatly. The term Post-Impressionism was coined.

Business research paper - Essay Example As part of the inquisition the research will make use of timestamps such as Weblog and news articles to feed as input materials to generate results that will be presented graphical. The graphical details will highlight major sentiments like anxiety, despair and disappointment. In addition, the development that comes with each of sentiments will be presented to illustrate for instance how the earthquake news was received and the corresponding reactions that followed afterwards. Essentially, the main motivation for using this method is for convenience since the participant dependent and independent variables are within meaningful reach. There are a good number of published as well as unpublished literature on the subject of sentiment analysis in both the academic and policy circles. Incidentally, in this review the most astounding works that have significant bearings on the subject matter will be reviewed. To begin with, it is undoubtedly prudent to establish the internal dynamics of sentimentalism. The paper benefits from the earlier work of pioneers who discovered the so-called semantic orientation of examination of a statement or a written material (Turney, 2002). Also according to Pang et la (2002), a sentence can be assessed to identify the positive and negative elements contained in it. Unlike the above mentioned works, this work will be influenced by the system of multi-polar analysis in order to draw the clear distinction between this and other previous papers. In a related context, researchers Mishne and de Rijke (2006) have advocated for a system that can evaluate momentary changes in the moods of people, it is what they term "Moodviews." Fundamentally, the analysis is carried out with the aid of over one hundred sentiments. A good number of scholarly works have been carried out on the question of "topic detection and tracking" with each of these groups making their own proposals depending on what is deemed fit for each circumstances. Interestingly, there is a gross limitation of work that fully addresses the utilization of sentiments under the "topic detection and tracking" column and this is precisely what this paper will be addressing. The process will also incorporate what Havre et al (2002), called information visualization. Research Results At the end of the research the following outcomes represented below are expected to be generated. A graph will be plotted to highlight the sentiments generated especially in the wake of the turbulent earthquake that occurred a little while before the official opening of the 2008 International Olympic Games hosted in Beijing, China. The X-axis of the graph will capture the dates where as the resultant sentiments will be presented on the Y-axis. The main sentiments expressed here are shock, anxiety and despair. Conclusion The research will deal with analyzing momentary trends in sentiments generated from the pre-Olympics euphoria as well as the aftermath. Qualitative and quantitative

A Comparison between Male and Female Organizational Commitment and Dissertation

A Comparison between Male and Female Organizational Commitment and Turnover - Dissertation Example While various researches have been conducted on organizational commitment in the Western world, the Eastern corporate world, such as that of Qatar still lacks research on this topic. This research aims to uncover who organizational commitment differs among employees in terms of factors including but not limited to gender. In order to understand the concept of organizational commitment, this research depends largely on the contribution of Meyer and Allen and their three types of organizational commitment, affective, normative and continuance commitment. This research further takes inspiration from the organizational commitment scale developed by Meyer and Allen that is based on a Likert scale. The method of conducting the research was quantitative in nature where the questionnaire was inspired from Meyer and Allen’s organizational scale that was distributed among all the employees of XYZ Co., a leading gas company in Qatar. The results of the survey were analyzed using percenta ges and descriptive analysis. The results pointed to the fact that organizational commitment among males and females differs by the type; that is, males are more normatively committed with the organization while females are continually commitment. Affective commitment increases as employees move higher up in the organization because the organization gives more power in their hands. Table of Contents Chapter 1: Introduction 4 1.1.
