Socket programming - Research Paper Example However, sockets can also be used to facilitate communication on one computer being either as synchronous (blocking) or an asynchronous (non-blocking) socket (Luo etal., 2009). The difference between the two is that the blocking socket ensures socket operation to be completed before the program resumes the next execution. On the other hand, non-blocking socket usually allow the application to be responsive to other events The development of socket programming has achieved notable success over the years. It all started with the development of a free version of UNIX operating system in the year 1978, the BSD UNIX by Bill Joy. The second free version of BSD was released some months later which become the internet backbone due to its open source concept. On this front, it was notable in facilitating the development of TCP/IP with UNIX as the research platform (Parziale etal., 2009). This breakthrough into spearheading internet research using UNIX operating system made Bill Joy to be regarded as the â€Å"Edison of the Internet†. The socket interface development was initially conducted on BSD UNIX after which it was later incorporated into other operating system to simplify porting applications (Mansfield & Antonakos, 2010). Stream socket (SOCK_STREAM) – mainly involved in connection-oriented data transmission where the data is usually considered as a stream of bytes. Uses the bind (), listen (), accept (), and connect function to establish connectivity and develops flow control to ensure there is no data overruns. To effect communication successfully, a stream socket requires that the two parties involved in the communication process to establish the connection first before initiating the dialog process. The client program requests for connection after which the server program determines the suitable socket connection. The data being transmitted is bound to arrive following its sending order without any duplication or errors.

Importance of psychology in nursing and how gender plays a role Dissertation

Importance of psychology in nursing and how gender plays a role - Dissertation Example With its over-arching knowledge and general applicability to various discourses, psychology has been successful in having an impact on the profession of nursing as well. The profession of nursing entails, â€Å"the use of clinical judgment in the provision of care to enable people to improve, maintain, or recover health, to cope with health problems and to achieve the best possible quality of life whatever their disease or disability until death† (Glasper & Richardson, pp. 95, 2006). As obvious from this definition, nursing is inevitably related to psychology and its inferences since it does not only deal with humans (patients) but also has a critical impact on how nurses deal with different patients, as well as on the element of care and strategies that focus on the stimulation of quicker recovery. Thus, in all aspects, psychology and nursing are highly interrelated with one affecting the performance of the other. However, there is more to it than just the element of care and its psychological underlying themes. What is particularly interesting, especially in the light of modern advancements in career planning and professional motivations is the issue of gender in nursing. Recently, what was considered to be only women’s profession, first of prostitutes and nuns and later on, by the virtue of Florence Nightingale, of decent educated and cultures young women, is now profession of young men. In specific, there has been a significant rise in number of male nurses in the past decade globally. Interesting to note; however, are the differences and similarities between these trends and behaviors of caring and treating the patients by male and female nurses individually (Miers, 2000). In this regard, this paper will attempt to discover these differences and trends and identify response patterns particular to each of them. Brief analysis of the literature indicated research of Kalisch & Kalisch (1987) who put efforts to explore change in the image of nurs ing profession all along the passage of time. In specific, concise description of their hypothesis is that perception of the female nurse as Angel of Mary in late 19th century evolved into that of Girl Friday prevalent in 1920’s. Subsequently, during World War II, the nurses played the role of Heroines followed by their image as Wives and Mothers in 1950’s and from mid 1960’s until 1980’s, they confronted their perception as sex objects (Kalisch & Kalisch, 1987). However, since after 1980s, the image of female nurses has changed radically. Nowadays, society look at the nurses as middle-aged, Caucasian, overworked and female representatives of the society. In addition, one can come across many reasons to evaluate how the femininity in the perception of nursing has accentuated. Specifically, nursing came about as a popular profession for women who wanted to step outside their homes and work. Therefore, since the very beginning, society perceived it as a fem inine profession. Several other researchers (Miers, 2000) noted that during the World Wars, this gender divide became all the more visible as the women took up the care-giving role and supported their male counterparts who went and fought in the battle. On the other hand, men were also discouraged as they confront rejection while acquiring admission in nursing schools.

In other words, the freedom of Coles to set prices for their own products. Pricing power of a firm largely depends on the demand for its goods and services. A firm enjoys the maximum pricing power depending upon the price elasticity if its product or service. Price Elasticity according to Mulhearn and Vane in the book 'Economics' is "measures the responsiveness of the quantity demanded of a particular good or service to changes in its price ." Coles being the second largest supermarket chain in Australia to a certain extent does dictate prices and enjoys an edge over smaller retail stores. However in a Public submission report to the ACCA (Australian Competition and Consumer Commission) Coles has stated "Coles is committed to delivering value to customers every day.

Nuclear Family and Matrix Organizational Structure Essay

Nuclear Family and Matrix Organizational Structure - Essay Example In cases where the family cannot support itself and the 2 parent limitation is exceeded the family is better known as an extended family. The term extended family point to a situation where the immediate family members are living together with their own nuclear family and an extended family would comprise of grand parents, uncles, aunts etc. The nuclear family system has a number of advantages. The first one worth mentioning here is that there is no particular 'Head of The Family' and basically you are on your own. To put it in a colloquial representation there is basically no one to stop you from anything. Having labeled this as an advantage it is also worth mentioning that this can be a good or a bad thing. Since you are on your own you take your own decisions and therefore whatever the consequences of a particular be the person involves does not have to blame any one else but him/herself whenever a decision is thought bout in retrospect. The flip side to this is that normally the Head of a family has far more experience than the younger ones involved and normally the Head is in a better position to judge and decide if a particular step or decision can be helpful or not therefore in a nuclear family setup this fruit of experience is missed out. The next point is that you raise your children in your own style and there is rarely any interference from any elders. This again has both sides to it since having the choice of raising your kids your own way does help your kids to have orientations of the ways of life of the future and they don't have to be compliant to the standards of elders. At the same time again the experience of an elder of the family is missed out here. Compared to a joint family system in a nuclear family you earn and spend on your own luxuries without having to contribute anything towards the family pool. One note worthy issue here is that as soon as a marriage breaks the whole family come crumpling down in a nuclear family. As compared to this in a joint family the children of the broken marriage are normally taken care of by the grand parents. Two in a Box This concept is based on the idea of two leading roles in an organization/group where the two have different focuses as compared to each other but the two together help the organization move towards its goal in a very efficient manner. Matrix Organization In structure the team consists of multifunctional team members and encourages a horizontal communication and authority rather than the traditional vertical flow of authority. The matrix structure essentially abandons the concept of one boss or one head for a division/department. It normally enforces an amalgamation of individual skills by involving individuals from different departments; this structure is usually very effective for large projects or for a specific product's development. The way this structure works is that for a specific project, for which the matrix is enforced, the day to day progress report goes to the product of project head where as the individuals continue reporting for their over all performances to their main departmental head. The positive about this

Modern Asian Theatre Research Paper Example | Topics and Well Written Essays - 1250 words

Modern Asian Theatre - Research Paper Example In this regard, this paper will be divided into three parts. The first part will provide a brief review on what theatre is and its basic foundations, as well as describe the common characteristics of Asian theatre. The second part will zero in on Indonesian theatre and its tight connection with the country’s socio-political history. The last part will present a conclusion that justifies the paper’s thesis—that modern Indonesian theatre is a strong reflection of the birth and growth of a nation. Theatre, unlike painting and sculpture, can be regarded as a unique art form for it consists of actors that perform in real time before a live audience. Although it is difficult to trace the exact origin of theatre, most scholars and historians agree that the first known dramatic presentation happened in Africa, possibly as early as 3300 B.C. The basic foundations of dramatic presentations are anchored on the culture and tradition of people. As such, theatre is comprised of two essential elements—ritual and storytelling (Cohen 222). A ritual is a collective ceremony performed by members of society for religious and cultural reasons. Ethnic plays are usually filled with activities that aim at impressing or advocating a specific belief over its intended audience (like the killing of an animal to worship a god or dancing uninhibitedly to celebrate an important occasion). Storytelling as a key component of theatre, on the other hand, necessitates an audience to artistically relay a significant message. Because of this, storytelling plays often generate character impersonation and utilize a more coherent narrative. Asian theatre, unlike Western ones that put premium on the clear narration of a story, is more sensual and melodic. Thus, it is claimed that there are five common characteristics of Asian theatre (whether it be an Indian Sanskrit drama, a Chinese Xiqu or a Japanese Kabuki): Its language are

Financial Analysis of Steel Industry - Arcelormittal and Us Steel Essay Example for Free

Financial Analysis of Steel Industry Arcelormittal and Us Steel Essay Stock Evaluation Project Steel Industry Industry Analysis Steel is a part of metals and mining industry which is highly cyclical in nature, and when the economy at large suffers, this industry suffers with it. The most recent five years have been a struggle for this particular industry along with uncertain economic indicators, and steel companies’ stocks have trended downwards. The metals and mining industry is comprised of companies that engage in exploration, mine development, and ore mining. The industry includes precious metals mining for metals such as gold, silver, platinum as well as mining and processing industrial metals such as steel, copper, aluminum. The industry is mature, cyclical, capital intensive and dominated by large companies. Some of the major names in the Steel Sector of this industry are Commercial Metals (CMC), Steel Dynamics (STLD), Reliance Steel (RS), AK Steel (AKS), ArcelorMittal (MT), U.S.Steel (X). The US steel industry is currently worth more than $50 billion with annual growth rates around 1% to 2%. Process chains are long with high production volumes. Recently, large quantities of low-cost imports have impeded growth. However, the industry has seen enhanced productivity, energy efficiency, and higher yield due to restructuring, downsizing, and widespread implementation of new technologies. In the coming years, overcapacity and price instability may remain critical. Thereby, efficient production, better-suited products, enhanced capacity utilization and environmentally friendly practices are vital factors to future success. Demand comes from transportation, packaging, consumer electronics, construction, aerospace and power companies, which leads industry, overtly responsive to economic conditions. Companies are responding to pricing pressures through consolidation and vertical integration, which is aimed at streamlining the supply chain. Future growth for the US metals and mining industry also depends upon demand from BRIC nations, developing countries, and domestic consumers. The industry has always faced a number of challenges including environmental concerns, deteriorating ore grades, overproduction, technological changes, and the global economy. Intense competition from nations such as Canada, Russia, China and Mexico pose threats to the US mining industry because those nations have lower labor costs, lax  environmental regulations and lower operating costs. Sustainability of high prices, resurgent global demand, particularly from the Asia-Pacific region, and signs of increasing industrial output across Europe and the United States may boost industry performance. Conclusively, in anticipation of J-curve yield in the industry index, we can expect greater demand in near future due to a combination of rising GDP, another increase in auto sales, and inventory accumulation by distributors, which would further lead to an increase in the volume of steel shipped in 2013. In the Figure 1.1 below, one could clearly see the downward trend of the Dow Jones US Steel Index for the last five years. And as we all know, what goes down comes back up therefore, we must rebalance our portfolios along with this cyclicality. Figure 1.1 Dow Jones US Steel Index (Point and Figure Chart) U.S.Steel (X) United States Steel was founded in 1901 and is headquartered in Pittsburgh, Pennsylvania. United States Steel Corporation, through its subsidiaries, engages in the production and sale of steel products primarily in North America and Europe. The company has gone through a business cycle in the past 10 years and currently at its low yet a stable condition. This is due to several reasons, which are explained clearly by the ratios and the Z-score, as plotted by the help of Altman Z’s Model. The companys liquidity has been fairly stable besides the times of 2008-2009 financial crises. If we smooth out an average for turnover measure, we could also conclude that the company’s management is doing fairly well in using the assets. Financial Leverage measure seems to be the only component affecting the Altman Z Score significantly, inflicting a bias in the usage of the model to solely depend on this method of deriving the company health. Also, if we draw a line at 2.0 ratio level, there is a bubble growth in the Z-score during 2005 and 2008, as shown in the figure 1.2 below. Figure 1.2 Altman Z-score Model for U.S.Steel ArcelorMittal (MT) ArcelorMittal engages in the production and marketing of finished and semi-finished carbon steel and stainless steel products worldwide. The company serves automotive, appliance, engineering, construction, energy, and machinery industries. The company, formerly known as Mittal Steel Company N.V., was founded in 1989 and is headquartered in Luxembourg, Luxembourg. The stock performance has been quite interesting for this company over past 10-12 years. From $0.63/per share in 2001 to the highs of $97 just prior to its downfall, to $12/share approx. after 12 years, tells us a lot about the business cycle of steel sector. As plotted by the ratios derived by Altman Z-Score model below, it is very clear that besides Turnover and Financial Leverage ratios, no other ratio changed significantly in last 10 years and the company stock performed rationally if we consider business cycle but irrationally, if we consider the all other financial measures. Again the spike in the Z-score in the early 2000s reflects the spike in Financial Leverage of the company. However, at this point in time, the company looks as in congruence to the low levels of the industry, yet healthy and we could anticipate an upcoming up-trend in its performance. Figure 1.3 Altman Z-Score model for ArcelorMittal
