On the surface, baseball cards appear to be little more than uninteresting object of child's play; yet they provide invaluable data for assessing unique aspects of the social order. They reveal much about the state of society when they were produced and the people who collected them. This paper examines the unique numbering system the Topps company developed to differentiate among the “royalty of the diamond” from 1956 to 1980. Their system assigned to each card in a set a number that explicitly designated its placement, while implicitly establishing a hierarchical ordering among the players, ostensibly based on performance. It is arguable whether the numbering system Topps developed was based on performance or the ascribed characteristic of race. The results of our work suggest that player performance, not race, was the primary factor in the assignment of “prestigious” card numbers in Topps’ system. 相似文献

This article explores the cultural and structural forces that help influence the reproduction of sexist, misogynistic, and antifeminine attitudes among men in team sports. It first shows how the segregation of men into a homosocial environment limits their social contact with women and fosters an oppositional masculinity that influences the reproduction of orthodox views regarding women. However, this research also shows that when these same men compete in the gender-integrated sport of cheerleading, they positively reformulate their attitudes toward women. These findings therefore suggest that gender-integrating sports might potentially decrease some of the socionegative outcomes attributed to male team sport athletes, possibly including violence against women. 相似文献

This study addresses two questions. First, among the three major perspectives on integration (i.e., zero‐sum, pluralist, and selective integration) suggested in the literature, which is the dominant pattern of the participation level in informal social activities in the ethnic community and in the wider society among new immigrant groups? Second, how well do the factors suggested by these three perspectives explain these patterns? Based on recently collected data about Chinese immigrants in Toronto, Canada, the analyses suggest that nearly half the respondents claim a low level of social participation. Among those who do participate, the pluralist integration pattern is the dominant pattern of participation in informal social activities among today's Chinese immigrants. Though the analysis shows the consistent effect of human capital resources on the pluralist integration patterns, there is no significant effect of either human capital resources or duration in the country on the zero‐sum and selective patterns. Implications of the results are discussed. 相似文献

The elderly are particularly susceptible to disease, yet the biological mechanisms that bring about this susceptibility remain unclear. Using atherosclerosis as a model chronic illness, we review how recent studies of bone marrow-derived vascular repair systems in mice and humans provide new insights into the causes and potential cures for age-related illness. Organisms are born with a finite capacity for stem cell-mediated repair after chronic exposure to tissue injury. Once that capacity is exhausted, a cycle of pathological inflammation ensues and leads to overt disease manifestations. Augmentation of stem cell-mediated repair systems may provide a novel means of treating or preventing many age-related illnesses. 相似文献

Family size is an important determinant of family well-being, and it is a good predictor of poverty. This study examines effects of waiving the 100-hour rule, by family size, and distinguishes between the "work-incentive effects" and the "eligibility effects" of the waiver. The 100-hour rule limits eligibility to aid to two-parent families in which the principal earner is unemployed or underemployed (works fewer than 100 hours per month). The study uses data from the Link-Up randomized experiment, conducted in California's Central Valley, from 1992 to 1994. The findings show that the eligibility effect of the waiver does not differ by family size, but the work-incentive effect does. 相似文献

Trajectories of prosocial behavior and physical aggression between 6 and 12 years of age were identified for a sample (N=1,025) of males. The trajectories were then used to predict school dropout and physical violence at age 17. Using a group‐based semi‐parametric method, two trajectories of prosociality (low and moderate declining) and three trajectories of physical aggression (low, moderate, and high declining) were obtained. Only a small minority (3.4%) of the boys were characterized by both high aggression and moderate prosociality. Physical aggression predicted both school dropout and physical violence, but contrary to expectations, prosocial behavior did not have additive or protective effects. 相似文献

An analysis of the effects of diabetes and generalized atherosclerosis on death due to ischemic heart disease or stroke was conducted using multiple cause mortality statistics. Specifically, all U.S. deaths in 1969 were classified into two groups on the basis of whether diabetes or generalized atherosclerosis was mentioned anywhere on the death certificate. Then race and sex specific analyses were made of ischemic heart disease deaths (or alternately of stroke deaths) using modified life table techniques for each group (one with the specified chronic disease and one without). Comparisons were made of mortality due to the acute circulatory events (ischemic heart disease or stroke) in the two groups to determine the implications of the chronic disease for the progression of the circulatory disease events. It was found, according to expectations, that diabetes and generalized atherosclerosis play very different roles in deaths due to stroke and ischemic heart disease. 相似文献

A portion of the graduate program in clinical community psychology at SUNY Buffalo was subjected to a jury trial as a form of program evaluation. The theory of the trial as evaluation, the problems of implementation, and a posttrial evaluation are discussed. The trial, while time-consuming, especially in its pretrial phases, has the potential for presenting a dramatic picture of a program through the medium of human testimony. The jury was able to arrive at clear decisions on questions put to it, with a high degree of confidence. Decision makers accepted some of the jury's conclusions, and subjective evidence suggests that many of the controversial issues which generated the trial were resolved for the group by the procedure. The posttrial evaluation revealed limitations, such as evidence which was not presented at the trial. The experience proved useful for purposes of interdisciplinary education, providing another lens through which the evaluation problem could be viewed. 相似文献

Seven Circles is a substance abuse prevention coalition in Southeast Alaska with a two-tiered structure consisting of local partnerships joined together in a regional coalition. Seven Circles incorporates a youth/adult partnership approach to accomplish its activities. This article describes the results of four annual administrations of a partnership member survey designed to assess the development and implementation of youth/adult partnerships in the local projects, assess the value of the partnerships to the participants, and gather feedback about the functioning of the Seven Circles Coalition. The results support the youth/adult partnership model and are also discussed in the context of youth empowerment. 相似文献

As part of its periodic re-evaluation of particulate matter (PM) standards, the U.S. Environmental Protection Agency estimated the health risk reductions associated with attainment of alternative PM standards in two locations in the United States with relatively complete air quality data: Philadelphia and Los Angeles. PM standards at the time of the analysis were defined for particles of aerodynamic diameter less than or equal to 10 microm, denoted as PM-10. The risk analyses estimated the risk reductions that would be associated with changing from attainment of the PM-10 standards then in place to attainment of alternative standards using an indicator measuring fine particles, defined as those particles of aerodynamic diameter less than or equal to 2.5 microm and denoted as PM-2.5. Annual average PM-2.5 standards of 12.5, 15, and 20 microg/m3 were considered in various combinations with daily PM-2.5 standards of 50 and 65 microg/m3. Attainment of a standard or set of standards was simulated by a proportional rollback of "as is" daily PM concentrations to daily PM concentrations that would just meet the standard(s). The predicted reductions in the incidence of health effects varied from zero, for those alternative standards already being met, to substantial reductions of over 88% of all PM-associated incidence (e.g., in mortality associated with long-term exposures in Los Angeles, under attainment of an annual standard of 12.5 microg/m3). Sensitivity analyses and integrated uncertainty analyses assessed the multiple-source uncertainty surrounding estimates of risk reduction. 相似文献
