Few public relations practitioners rise to the level of head of an organization; therefore, this study on former National Football League Commissioner Pete Rozelle presents a unique opportunity to examine how an organizational leader with PR work experience managed a business operation. Drawing upon unique historical records, this study demonstrated how Rozelle used his public relations background to help make the NFL America's number one sport (in terms of revenue and in fan polling).  相似文献

This study examines Adam Smith's concept of national product (referred to as Smithian Domestic Product, or SDP) which he articulated in The Wealth of Nations. In contrast to Gross Domestic Product (which measures the production of things that have value), Smith's measure is more plutological. It measures the production of things critical for the accumulation of wealth. Given the global interest in economic growth and improvements in living standards, SDP is potentially useful as a complement to the GDP measure. As a preliminary effort to assess that potential, SDP and GDP estimates for the U.S. economy were compared for the period from 1949 to 2002. For two major macroeconomic events in the past decade (the economic boom of the 1990s and the recent recession), SDP appears to perform better than the GDP measure.  相似文献

Researchers attempting to understand the experience of subjective well-being have relied heavily on self-report measurement. Recent research focused on this method has demonstrated that a number of factors, such as the current mood of the respondent and the cognitive and social context surrounding the response, can significantly influence response to items inquiring about global subjective well-being or satisfaction with life. In the present study, several measurement strategies (e.g., single-item measures, multiple-item scales, and memory search tasks) were compared with regard to their susceptibility to such influences. Although some evidence for effects due to item-placement or transient mood were found, all of the global measures of subjective well-being and life satisfaction has significant convergence with peer-reports, and the single-item measures showed good temporal reliability across a one-month interval. The data provide evidence for a significant degree of stability in subjective well-being and life satisfaction.  相似文献

This paper describes an empirical study (n = 699) of occupational stress in a Scottish police force. The self-perceived stress associated with a variety of organizational and opearational stressors was examined along with the associated distress in the police officers in terms of symptoms of anxiety, somatic complaint, severe depression and social dysfunction. The analysis revealed that in spite of the potential that police work offers for exposure to adverse opeational situations such as violence or death, the highest levels of associated stress lie in relation to organizational factors such as officers' perceptions of staff shortages, inadequate resources, time pressures, lack of communication and work overload. Differential rates of perceived stress are reported accordng to gender, rank and working location. This paper further validates previsous research on stress in British police and addresses the situation from a Scottish perspective.  相似文献

Evolutionary ecology is the study of evolutionary processes, and the ecological conditions that influence them. A fundamental paradigm underlying the study of evolution is natural selection. Although there are a variety of operational definitions for natural selection in the literature, perhaps the most general one is that which characterizes selection as the process whereby heritable variation in fitness associated with variation in one or more phenotypic traits leads to intergenerational change in the frequency distribution of those traits. The past 20 years have witnessed a marked increase in the precision and reliability of our ability to estimate one or more components of fitness and characterize natural selection in wild populations, owing particularly to significant advances in methods for analysis of data from marked individuals. In this paper, we focus on several issues that we believe are important considerations for the application and development of these methods in the context of addressing questions in evolutionary ecology. First, our traditional approach to estimation often rests upon analysis of aggregates of individuals, which in the wild may reflect increasingly non-random (selected) samples with respect to the trait(s) of interest. In some cases, analysis at the aggregate level, rather than the individual level, may obscure important patterns. While there are a growing number of analytical tools available to estimate parameters at the individual level, and which can cope (to varying degrees) with progressive selection of the sample, the advent of new methods does not reduce the need to consider carefully the appropriate level of analysis in the first place. Estimation should be motivated a priori by strong theoretical analysis. Doing so provides clear guidance, in terms of both (i) assisting in the identification of realistic and meaningful models to include in the candidate model set, and (ii) providing the appropriate context under which the results are interpreted. Second, while it is true that selection (as defined) operates at the level of the individual, the selection gradient is often (if not generally) conditional on the abundance of the population. As such, it may be important to consider estimating transition rates conditional on both the parameter values of the other individuals in the population (or at least their distribution), and population abundance. This will undoubtedly pose a considerable challenge, for both single- and multi-strata applications. It will also require renewed consideration of the estimation of abundance, especially for open populations. Thirdly, selection typically operates on dynamic, individually varying traits. Such estimation may require characterizing fitness in terms of individual plasticity in one or more state variables, constituting analysis of the norms of reaction of individuals to variable environments. This can be quite complex, especially for traits that are under facultative control. Recent work has indicated that the pattern of selection on such traits is conditional on the relative rates of movement among and frequency of spatially heterogeneous habitats, suggesting analyses of evolution of life histories in open populations can be misleading in some cases.  相似文献

A national sample of marriage and family therapists (MFTs) was used to describe practice patterns of MFTs whose clients use psychotropics and to compare medicated and nonmedicated clients. Marriage and Family Therapists (n=283) reported on 195 medicated and 483 nonmedicated adult clients. Clients (n=375) rated their improvement and satisfaction with treatment. Results showed that 91% of MFTs treat medicated clients, and these clients accounted for 25% of MFT cases. Medicated clients were most often seen in individual therapy, had more serious medical problems, and showed greater cumulative improvement in relational functioning. Therapists from MFT educational backgrounds had fewer medicated clients than MFTs from other educational backgrounds.  相似文献

There are nonsexual reasons that may motivate people to seek out sexual activity with others. Some men who have sex with men may seek out sex environments to engage in sexual behavior. Among the nonsexual reasons that exist for men who have sex with men is a desire to escape from distressing thoughts and feelings. The amplified sexuality and other unique characteristics of sex environments allow men to have more intense emotional experiences around sex. Using the cognitive escape model as a theoretical foundation, this analysis focuses on the emotional vulnerability that some of the men who visit these venues may be avoiding and how their experiences at these venues might act as releasing mechanisms to alleviate dissonant thoughts and feelings. Implications for public health services and future research are discussed.  相似文献

The authors investigated illicit use of stimulant medications at a midwestern university. They used a questionnaire to (a) examine the extent to which university students illicitly used stimulant medications prescribed for attention-deficit hyperactivity disorder; (b) determine why college students abused such drugs; and (c) identify the factors that predicted illicit use of prescribed stimulant medication. Findings revealed that 17% of 179 surveyed men and 11% of 202 women reported illicit use of prescribed stimulant medication. Forty-four percent of surveyed students stated that they knew students who used stimulant medication illicitly for both academic and recreational reasons. Students reported they experienced time pressures associated with college life and that stimulants were said to increase alertness and energy. Regression analysis revealed that the factor that predicted men's use was knowing where to get easily acquired stimulant medication, whereas the main predictor for women was whether another student had offered the prescribed stimulants.  相似文献

Social scientists have expressed strong views on corporate influences over science, but most attention has been devoted to broad, Black/White arguments, rather than to actual mechanisms of influence. This paper summarizes an experience where involvement in a lawsuit led to the discovery of an unexpected mechanism: A large corporation facing a multibillion-dollar court judgment quietly provided generous funding to well-known scientists (including at least one Nobel prize winner) who would submit articles to open, peer-reviewed journals, so that their unbiased science could be cited in an appeal to the Supreme Court. On balance, the corporations most effective techniques of influence may have been provided not by overt pressure, but by encouraging scientists to continue thinking of themselves as independent and impartial.This is a revised version of a paper presented at the annual meeting of the American Sociological Association, Atlanta, GA, August 2003.  相似文献
