Prestige hierarchies, common to all organizations, are considered for positions at a university. Davis and Moore (1945) have called such stratification in any social system a universal necessity. Using procedures developed to measure prestige of occupations in national surveys, the attribution of prestige attached to university positions was determined. One hundred and eight positions were scaled, and the scale's validity and underlying scaling criteria were evaluated. It appears that university prestige is a microcosm of national prestige, and seems to have a similar socioeconomic base. 相似文献

Few studies have examined the impact of an increased physical demand on batting performance, especially over extended periods of play. Therefore, the purpose of this study was to determine the physiological and perceptual responses of batsmen scoring a simulated limited overs century, and to link these to sprint times and accuracy of the impact of the ball on the bat. Seventeen male, university level cricketers, performed a batting protocol (BATEX©), typical of a limited overs century. The protocol consisted of six stages, each of five overs, with each stage matched to a specific phase of play. Throughout the protocol heart rate (HR), central ratings of perceived effort (RPE), sprint times and impact accuracy were recorded. HR fluctuated as a function of exercise intensity (124.16–159.61?bpm). Central RPE increased as a function of intensity and duration (11.87–16.04). Sprint times got slower over time (5.67–5.81?s), while impact accuracy improved significantly (p?.05) after stage one and then plateaued for the remainder of the protocol (64.81–57.39?mm). In conclusion, the protocol significantly impacted cardiac strain and perceptual responses negatively impacting sprint times with an improvement in batting accuracy. 相似文献

Our study was motivated by the fact that, despite the increasing pervasiveness of political advertising in the political process of many democracies, little empirical research has been conducted to unveil common patterns or crucial differences of political spots across cultural boundaries. Our study thus provided one opportunity to gain better understanding and insights into how media phenomena are related to cultural orientation by comparing and contrasting the content of political spots across the United States and South Korea. In particular, this study analyzed verbal components of political spots in both US and Korean presidential elections over the past 20 years. To the extent that clear differences exist between American and Korean cultural patterns, political spots, which are a conspicuous indicator of cultural values, appear to manifest these differences quite strongly. The findings of this study provide evidence that political advertising primarily reflects the uniqueness of indigenous cultures. 相似文献
