abstract In Political Liberalism and later work John Rawls has recast his theory of justice as fairness in political terms. In order to illustrate the advantages of a liberal political approach to justice over liberal non‐political ones, Rawls discusses what kind of education might be required for future citizens of pluralistic and democratic societies. He advocates a rather minimal conception of civic education that he claims to derive from political liberalism. One group of authors has sided with Rawls’ political perspective and educational proposal, holding that a political approach and educational requirements that are not too demanding would have the advantage of being acceptable to a wide range of citizens with different religious, moral and philosophical perspectives. A second group of authors have criticized Rawls’ educational recommendations, holding that the production of a just society composed of reasonable citizens requires a more demanding civic education and, hence, that the political approach is not viable. The present paper argues that both groups are only partially right, and that there is a third way to understand civic education in Rawlsian terms, a way that is political but not minimal. 相似文献

In five experiments, we examined 3‐ to 6‐year‐olds’ understanding that they could gain knowledge indirectly from someone who had seen something they had not. Consistent with previous research, children judged that an informant, who had seen inside a box, knew its contents. Similarly, when an informant marked a picture to indicate her suggestion as to the content of the box, 3‐ to 4‐year‐olds trusted this more frequently when the informant had seen inside the box than when she had not. Going beyond previous research, 3‐ to 4‐year‐olds were also sensitive to informants’ relevant experience when they had to look over a barrier to see the marked picture, or ask for the barrier to be raised. Yet when children had to elicit the informant's suggestion, rather than just consult a suggestion already present, even 4‐ to 5‐year‐olds were no more likely to do so when the informant had seen the box's content than when she had not, and no more likely to trust the well‐informed suggestion than the uninformed one. We conclude that young children who can ask questions may not yet fully understand the process by which they can gain accurate information from someone who has the experience they lack. 相似文献

A growing literature has observed a significant reduction in pain sensitivity among hypertensive animals and humans. It is uncertain whether a reduced sensitivity to pain can be observed in nonnotensive individuals who go on to develop high blood pressure. Blood pressure (BP) was reassessed in one hundred fifteen 19-year-old boys initially tested at age 14, when they were also presented with a pain stimulus (mechanical finger pressure). Hierarchical regression analyses indicated that information regarding pain tolerance improved prediction of changes in systolic and diastolic blood pressure beyond that afforded by differences in BP at age 14, parental history of hypertension, and body mass index. These analyses suggest that pain sensitivity may be associated with physiological processes involved in the development of sustained high blood pressure. 相似文献

A meta-analysis of published studies with adult human participants was conducted to evaluate whether physical fitness attenuates cardiovascular reactivity and improves recovery from acute psychological stressors. Thirty-three studies met selection criteria; 18 were included in recovery analyses. Effect sizes and moderator influences were calculated by using meta-analysis software. A fixed effects model was fit initially; however, between-studies heterogeneity could not be explained even after inclusion of moderators. Therefore, to account for residual heterogeneity, a random effects model was estimated. Under this model, fit individuals showed significantly attenuated heart rate and systolic blood pressure reactivity and a trend toward attenuated diastolic blood pressure reactivity. Fit individuals also showed faster heart rate recovery, but there were no significant differences in systolic blood pressure or diastolic blood pressure recovery. No significant moderators emerged. Results have important implications for elucidating mechanisms underlying effects of fitness on cardiovascular disease and suggest that fitness may be an important confound in studies of stress reactivity. 相似文献

Adults are better at recognizing familiar faces from the internal facial features (eyes, nose, mouth) than from the external facial features (hair, face outline). However, previous research suggests that this “internal advantage” does not appear until relatively late in childhood, and some studies suggest that children rely on external features to recognize all faces, whether familiar or not. We use a matching task to examine face processing in 7-8- and 10-11-year-old children. We use a design in which all face stimuli can be used as familiar items (for participants who are classmates) and unfamiliar items (for participants from a different school). Using this design, we find an internal feature advantage for matching familiar faces, for both groups of children. The same children were then shown the external and internal features of their classmates and were asked to name or otherwise identify them. Again, both age groups identified more of their classmates correctly from the internal than the external features. This is the first time an internal advantage has been reported in this age group. Results suggest that children as young as 7 process faces in the same way as do adults, and that once procedural difficulties are overcome, the standard effects of familiarity are observed. 相似文献

A national survey was conducted to compare the background and career characteristics of men and women engineers differing in the number of years since they completed their BS degrees (0–5, 6–10, 11–15, and 16–20 years). The parents of women engineers were more likely to have college degrees and to be employed in professional positions than were the parents of men engineers. Women engineers were less likely to be married and were more likely to be childless than were the men. Both men and women were influenced by courses and work–related factors in their decisions to pursue engineering, but men made their career decisions sooner than women. Although men and women reported comparable levels of technical responsibility in their present jobs, gender differences favoring men were found for supervisory responsibility and salary among those with more than five years of experience, with the gap between men and women increasing with experience. Men with 16–20 years of experience and all four degree cohorts of women endorsed the opinion that there are better opportunities for men than women in engineering. 相似文献
