This study examined two distinct theoretical explanations for the effect of attire on aiding behavior. The reinforcing value of attire itself predicted that well-dressed persons would always receive more assistance than poorly dressed persons. The reinforcing value of perceived similarity predicted that similar persons would receive more assistance than dissimilar persons. Female confederates (N=17) who were well-dressed or poorly dressed approached males and females in an airport or bus station asking for a dime to complete a telephone call. Well-dressed confederates received more money at the airport; poorly dressed confederates received more money at the bus station. These results were interpreted as support for the similarity hypothesis.An earlier version of this paper was competitively selected to be presented to the communication theory interest group at the Central States Communication Association convention in St. Louis, Missouri, April 5–7, 1979. 相似文献

Cette analyse des données d'une étude sur la mobilité canadienne révèle que le niveau d'éducation atteint par les immigrants qui sont arrivés au Canada à temps pour suivre les cours d'école primaire, semble être plus élevé que le niveau atteint par ceux qui sont arrivés avant ou après cet âge. Toutefois, comme la plupart des différences entre les catégories d'âge à L'arrivée ne sont guère significatives, statistiquement parlant, et comme les valeurs des mesures concises de la relation globale sont peu élevées, il y a lieu de douter si L'âge à L'arrivée exerce en soi un effet direct sur le niveau d'éducation atteint. Ces résultats sont en opposition avec ceux publiés par Inbar et donnent très peu d'appui à celui-ci, dont les conclusions font croire que L'âge à L'arrivée entraîne des conséquences différentielles pour L'acculturation. Analysis of Canadian Mobility Study data reveals that educational attainment tends to be higher among those who immigrated to Canada during grade school years than among those who immigrated earlier or later. However, as most differences between age-at-immigration categories are not statistically significant and as values for summary measures of the overall relationship are low, there is reason to doubt that age at immigration, in itself, exercises a direct effect on educational attainment. These findings contrast sharply with those reported by Inbar and provide little support for his conclusion that age at immigration has differential consequences for acculturation. 相似文献

Conclusions Social agency practitiooners can employ adolescent group therapy as an effective treatment mode, as long as a great deal of attention and planning is put into the details of group membership selection. The authors have presented suggestions and guidelines that can be used in overcoming the logistic problems inherent in forming an adolescent therapy group. We feel that proper pregroup planning is just as important in determining group results as is the ongoing group process. Group treatment does not necessarily incease a therapist's productivity or reduce the amount of time spent in therapy, but it does offer a unique experience which has certain qualitative advantages for teenagers experiencing behavioral and relationship problems within and, particularly, outside of the family system. 相似文献

The so-called “principal formulae” of planar integral geometry are conventionally couched in terms of the “kinematic density”dxdydθ. Here a corresponding theory with respect to the “Lebesgue density”dxdy, that is with rotations suppressed, is developed. The only real difference is that the new “fundamental formula of Blaschke”contains a term depending upon the relative orientations of the two domains involved. In particular, the remarkable iteration property of these formulae carries over. The usual principal formulae follow as a corollary of the formulae given here, upon, averaging over orientations. 相似文献

Despite many claims for and against the use of risk comparisons in risk communication, few empirical studies have explored their effect. Even fewer have examined the public's relative preferences among different kinds of risk comparisons. Two studies, published in this journal in 1990 and 2003, used seven measures of "acceptability" to examine public reaction to 14 examples of risk comparisons, as used by a hypothetical factory manager to explain risks of his ethylene oxide plant. This study examined the effect on preferences of scenarios involving low or high conflict between the factory manager and residents of the hypothetical town (as had the 2003 study), and inclusion of a claim that the comparison demonstrated the risks' acceptability. It also tested the Finucane et al. (2000) affect hypothesis that information emphasizing low risks-as in these risk comparisons-would raise benefits estimates without changing risk estimates. Using similar but revised scenarios, risk comparison examples (10 instead of 14), and evaluation measures, an opportunity sample of 303 New Jersey residents rated the comparisons, and the risks and benefits of the factory. On average, all comparisons received positive ratings on all evaluation measures in all conditions. Direct and indirect measures showed that the conflict manipulation worked; overall, No-Conflict and Conflict scenarios evoked scores that were not significantly different. The attachment to each risk comparison of a risk acceptability claim ("So our factory's risks should be acceptable to you.") did not worsen ratings relative to conditions lacking this claim. Readers who did or did not see this claim were equally likely to infer an attempt to persuade them to accept the risk from the comparison. As in the 2003 article, there was great individual variability in inferred rankings of the risk comparisons. However, exposure to the risk comparisons did not reduce risk estimates significantly (while raising benefit estimates), and Conflict-Claim respondents found the risk of the hypothetical factory less acceptable than No-Conflict respondents. Results suggest that neither risk comparisons nor risk acceptability claims are automatically anathema to audiences, but they may have tiny or unintended effects on audience judgments about risky situations. 相似文献

Millions of Medicare-age Americans are drug dependent, not because of addiction but because of common chronic health problems such as diabetes, heart failure, high blood pressure, and arthritis. Seniors are up in arms because drug company control of distribution and pricing of pharmaceuticals is eating away hard-earned nest eggs. Who cares? Where's the justice? 相似文献

Serious nonaccidental head trauma (NHT) can leave permanent neurological damage in children who survive abuse. This study reports on child welfare's handling of NHT cases compared with cases of physical abuse and head trauma due to neglect with regard to placement in foster care, reunification with family, and safety issues. The results show that workers placed children with NHT in foster care immediately after the abuse but treated them no differently than other physically abused children regarding reunification. 相似文献

Children in foster care have lower health status than do their peers and limited access to health care. The Illinois Department of Children and Family Services developed HealthWorks, a separate primary care preferred provider system for children in foster care. This study compared claims data for children in HealthWorks with children not enrolled in HealthWorks and with children in Aid to Families with Dependent Children (AFDC) who had never entered foster care. Children enrolled in HealthWorks were more likely than were other children to receive all of the services except general inpatient hospitalizations. They had greater odds of receiving general exams and physicians' services and were more likely to visit the emergency room than children who were not enrolled. They were more likely to receive all of the measured services when compared with children receiving Medicaid through AFDC. 相似文献

Food insufficiency is a significant problem in the United States, and poor African American women with children are at especially high risk. An inadequate household food supply can potentially affect the well-being of household members, but it is difficult to distinguish the effects of food insufficiency from risk factors for poor health that are also common among the food insufficient, such as poverty. We examined food insufficiency and physical and mental health among African American and white women (n = 676) who were welfare recipients in 1997. Controlling for common risk factors, women who reported food insufficiency in both 1997 and 1998 were more likely to report fair or poor health at the later date. Food insufficiency in 1998 was significantly associated with meeting the diagnostic screening criteria for recent major depression. Food insufficiency at both times and in 1998 only was related to women's sense of mastery. These findings add to growing evidence that household food insufficiency is associated with poor physical and mental health. 相似文献
