Locus of Control - Essay Example Each subject's perseverance level was rated after the task using a score range from 1 to 5. On average, subjects had a higher perseverance level on the Non-Frustration task than on the Frustration task. In this study, GESS and the ICI cannot be used to predict the degree of perseverance exhibited during a Frustration task. The concept of Locus of Control, which was originally developed by Julian B. Rotter in the early 1950's and is considered to be one of the most significant aspects of an individual's personality. It seeks to analyze the perception of an individual regarding the causes behind the happening or non-happening of certain events in his or her life (Rotter, 1966). The concept of Locus of Control is helpful in discerning the level of control that a person feels they possess in life. The study of Locus of Control would offer valuable contributions and theories that would further help in understanding and analyzing academic persistence as well as motivation. According to Strain (1993), the concept of Locus of Control has not yet been applied to the study of college students and their ability to persist at school. Individuals with internal Locus of Control are believed to be mentally more aware, able better equipped for learning, and highly motivated as compared to those with external Locus of Control (Stone and Jackson, 1975). ... And that a higher level of pessimism will correlate with a greater external Locus of Control. An optimist will perceive that many aspects of life are controllable and will therefore make efforts and take risks which will promote this belief, thus turning their Locus of Control internal. Whereas pessimists perceive that they are helpless to affect the events happening around them, so they will avoid taking steps to change things and thereby change their Locus of Control to external. According to Aspinwall and Brunhart (1996), optimists are more likely to be aware of their health risks and more informed about id as opposed to pessimists. This fact is further supported by the studies of Peterson, Seligman, and Vaillant (1988), whereby it was observed that people with pessimistic behaviour were in worse physical health on older age than their more optimistic counterparts. They also suggest a manner in which this "learned helplessness" which is a major cause of depression could be transformed into optimistic behaviour through cognitive therapy (Seligman and Martin, 1991). According to Gibson (2004), a large difference exists in the behaviour of gamblers where it was observed that optimists have high expectations of winning and so are likely to lose more than pessimists who rarely expect to win and bet lesser amounts after each consecutive loss. The concepts of optimism as well as pessimism, when studied in the light of cultural perspectives - in terms of dealing wit h international patients versus Hindu patients, Desai (1982) observes that reactions of people towards a given situation differs largely owing to their cultural backgrounds. While Armor and Taylor (1998) advocate the theory of "situated optimism" where people behave in an optimistic

Computer networks - Essay Example When the size W of the window gets to 0, transmission is stopped. Increasing the size of the windows enhances the bandwidths and makes the connection more efficient. Considering the basic functionality of the window size, that is holding the data by a device from its peer at any one time, increasing the size will then make the device to hold more data in the buffer at a time. This will enhance efficiency of communication. Over reliance on cumulative acknowledgements can cause data transfer inefficiency due to packet loss. Selective acknowledgement allows the receiver of the packets to be able to accept packets that are discontinuous but received correctly. This is in addition to the last successful contiguous byte that was received. This is the same situation that happens in a basic acknowledgement. In this mode, the acknowledgement specifies the SACK blocks and they are then conveyed through starting and ending sequence numbers. The SMTP processes the email address of the recipient in the same domain. When the names correspond, the message is directly routed to the POP3 server or the IMAP server. In this case, it is routed to the SMTP. In the case of the local client who is sending an email over the network, there will be no communication with another domain server. This communication will be from the internal mail server 10.1.0.10 from 10.1.0.10/8. On getting the email address, the SMTP server can connect to the recipient SMTP server. For the local client, this communication is maintained within the same server. For sending an email over the internet, the information is passed over to the border router. b) A DNS lookup occurs when a device supporting an IP asks the DNS server for the IP address that is associated with a certain domain name. When looking for postmaster@myertor.com, the series of lookups that will take place include; the primary DNS server will be seeking to establish the IP address for postmaster@myertor.com. The first request will
