Robert Putnam argues that much of the decline in social trust and civic engagement in the United States can be attributed to increased television viewing. People who watch a lot of television are likely to believe that the real world is as "mean" as the "television world," and hence withdraw their trust from other people and decline to participate in civic affairs. Using data from the GSS and other surveys, I show that it is not television that makes people less trusting, but optimism for the future that makes people more trusting. When measures of optimism were used as determinants of trust in the estimation of a simultaneous equation model, the effects of television vanished. There is no support for the argument that television makes us less trusting because of the content of the shows we watch, or for the argument that television makes us withdraw from civic engagement because of the amount of time consumed by viewing. In addition, no evidence for specific cohort effects was found.  相似文献

My purpose is to examine two of the foundations of medical ethics: the principle of autonomy and the concept of the human. I also investigate the extent to which health technology makes autonomy and humanness possible. I begin by underlining Illich's point that the same health technology designed to promote health and autonomy also is pathogenic. I proceed to analyse the Kantian concept of autonomy, a concept which is closely associated with health and which continues to determine current ethical thinking. In so doing, I uncover an unexpected ontological function of health technology, a function described in Heidegger's work on technology. Based on this discovery, I suggest that calls for Kantian autonomy may often be self-defeating or even sometimes harmful. I conclude by calling for continued ethical vigilance, but also for a questioning of the hitherto virtually unquestionable concepts of ethics and humanness which may themselves play a role in our era's greatest problems.  相似文献

Individuals engaged in a location task where the relevancy status [relevant (stimulus) vs irrelevant (distractor) information] of these locations was reversed from one trial (prime) to the next (probe). The results produced by these reversals (Distractor-to-Stimulus and Stimulus-to-Distractor) indicated that both stimulus and distractor items are given relevancy status labels which participate in the future processing at the labeled locations. These findings support the view that selective processing involves both `facilitatory' and `inhibitory' components. Further, unlike identity tasks, the data indicated that neither the formation nor the subsequent use of these `location' labels (stimulus or distractor) is related to the presence of a response conflict.PsycINFO classification: 2330; 2340  相似文献

A questionnaire was administered to 61 second graders. Sexual differences in occupational choices were apparent. Boys chose twice as many occupations as girls. Of 29 occupations selected as “most desirable,” only one was mentioned by both boys and girls. Of 37 occupations selected as “least desirable,” only two were mentioned by both sexes. More boys than girls knew their father's occupation. Although 76% of the girls knew their father's occupation, they did not select that occupation for themselves. A series of hypotheses based on the above data was generated.  相似文献
