What is a Proxy Server? Meaning, Functions and Goals

A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server evaluates the request according to its filtering rules. It may filter traffic by Internet Protocol (IP) address or protocol.

Theories of Motivation: Vroom’s Valence-Expectancy Theory

Vroom’s expectancy theory was originally developed by Victor H. Vroom, a Canadian psychologist, in 1964. Attacking Herzberg’s two-factor theory, Vroom offered an expectancy approach to the understanding of motivation. According to him, a person’s motivation towards an action at any time would be determined by an individual’s perception that a certain type of action would lead to a specific outcome and his personal preference for this outcome. Vroom’s expectancy theory consisted of two related models – the valence model and the force model. The valence model attempts to capture the perceived attractiveness, or valence, of an outcome by aggregating the attractiveness of all associated resultant outcomes. The force model of expectancy theory attempts to capture motivational force to act by associating the expectancy of resultant outcomes and their individual valences. These two models gave Vroom the opening to build his expectancy theory to the level that it is today most Continue reading

Standard Error in Hypothesis Testing

The standard error is an indispensable tool in the kit of a researcher, because it is used in testing the validity of statistical hypothesis. The standard deviation of the sampling distribution of a statistic is called the standard error. The standard error is important in dealing with statistics (measures of samples) which are normally distributed. Here the use of the word “error” is justified in this connection by the fact that we usually regard the expected value to be true value and the divergence from it as error of estimation due to sampling fluctuations. The term standard error has a wider meaning than merely the standard deviation of simple sampling because of the following reasons; The standard error is mainly employed for testing the validity of a given hypothesis. Mostly two levels of significance (0.05 and 0.01) are used for testing the validity of hypotheses. At 0.05 level of significance, Continue reading
