An analysis is presented of the longitudinal stability over the course of a year of characteristics of positive functioning and of individual and ecological developmental assets, among African American male youth involved in gangs or in community-based organizations (CBOs) serving youth. Evidence is provided for the potential of positive youth development among both groups of adolescents.  相似文献

This study investigated the impact of respondent gender, victim gender, and victim sexual orientation on judgments toward the victim of a depicted stranger rape. Respondents were required to read a scenario in which victim gender and sexual orientation varied between subjects, and to complete measures of behavioral blame, responsibility, and severity of the attack. Results revealed that male respondents made more anti-victim judgments than female respondents did. Male respondents judged gay male victims more negatively than they did other victims. Female respondents' judgments were pro-victim regardless of victim gender and victim sexual orientation. Results are discussed in relation to the feminist analysis of victim blame, and blame toward male rape victims. Implications for support services, particularly of male victims, are also considered.  相似文献

The present study was conducted to identify game parameters that would reduce the risk of abuse of video lottery terminals (VLTs) by pathological gamblers, while exerting minimal effects on the behavior of non-pathological gamblers. Three manipulations of standard VLT game features were explored. Participants were exposed to: a counter which displayed a running total of money spent; a VLT spinning reels game where participants could no longer stop the reels by touching the screen; and sensory feature manipulations. In control conditions, participants were exposed to standard settings for either a spinning reels or a video poker game. Dependent variables were self-ratings of reactions to each set of parameters. A set of 2(3) × 2 × 2 (game manipulation [experimental condition(s) vs. control condition] × game [spinning reels vs. video poker] × gambler status [pathological vs. non-pathological]) repeated measures ANOVAs were conducted on all dependent variables. The findings suggest that the sensory manipulations (i.e., fast speed/sound or slow speed/no sound manipulations) produced the most robust reaction differences. Before advocating harm reduction policies such as lowering sensory features of VLT games to reduce potential harm to pathological gamblers, it is important to replicate findings in a more naturalistic setting, such as a real bar.  相似文献

Students with sensory impairments comprise a heterogeneous group that is often underserved by rehabilitation and other social services. This underserved status has been attributed to poor interagency collaboration and eligibility issues, the low incidence nature of these disabilities, and the shortage of trained professionals to address the specialized needs of these individuals. This article examines important educational and vocational characteristics of this population to assist rehabilitation professionals in supporting more effective transitions into employment and other adult roles. Specific transition considerations include unique learning challenges, assessment issues, assistive technology, and accommodations. The article concludes with strategies for transition planning, community integration, and evaluating transition outcomes.  相似文献

Theory about the relationship of gender roles to delinquency illustrates the taken-for-granted assumption that as role expectations of people become more alike, their behavior becomes more similar. This paper tests the hypothesis that delinquency of androgynous and undifferentiated males and females is more similar in frequency than that of traditional males and females. Self-reported delinquency and self-ratings on scales of traditionally feminine and traditionally masculine expectations provide the data for this research. The analysis reveals that, as predicted, androgynous and undifferentiated males and females report more similar frequencies of delinquent behavior than do traditionally masculine males and traditionally feminine females. Undifferentiated respondents report the highest levels of delinquency among females, but the reverse pattern tends to hold for males. These patterns are analyzed and their importance for theory of gender and crime is suggested.  相似文献

The processes by which married couples come to the decision to have no children and the mechanisms they employ in reaction to pronatalist pressures were explored in interviews with 44 childfree husbands and wives. Two characteristic paths of decision-making were identified, Independent and Negotiated, and further categorization on the basis of degree of influence exerted by each spouse was proposed. Several mechanisms employed to counter pronatalist pressures were identified, including defense of the childfree lifestyle, devaluation of the parenthood status and denigration of parents, and avoidance of pronatalist company. Implications of these findings for the study of childfree marriages are discussed.  相似文献

This paper proposes that chemical and electromagnetic exposures pose technology‐related disability barriers for people who have acquired sensitivities to them and that these barriers should be integrated into our understanding of disability. I discuss pervasive chemical and electrical exposures as products of industrialism that first engender impairments and then act as disability barriers to those who develop intolerance to them. I also remark on unique aspects of environmental sensitivities in the context of the social model.  相似文献

Generally, hazards research and literature has treated natural and technological disasters as separate entities. This study attempts to determine how frequently interaction between these two types of disaster took place in the United States from 1980-1989. Data were collected by performing a literature review, contacting organizations and individuals active in hazards research and mitigation, and through a questionnaire sent to the emergency management agencies of all 50 states. The consensus derived from the data is that the number of incidents where natural and technological disasters interact is rising while preparations, which recognize the complications inherent in such combined events, remain cursory. There is a pressing need for states to record, and make available to managers, information regarding the number of combined natural/technological events affecting their areas. Only when such data are available will it be possible to make appropriate decisions regarding the best way to reduce the effects of a natural disaster causing a catastrophic release of hazardous materials.  相似文献

The binary derivative has been used to measure the randomness of a binary string formed by a pseudorandom number generator for use in cipher systems. In this paper we develop statistical properties of the binary derivative and show that certain types of randomness testing in binary derivatives are equivalent to well-established tests for randomness in the original string. A uniform method of testing randomness in binary strings is described based on using the binary derivative. We show that the new tests are faster and more powerful than several of the well-established tests for randomness.  相似文献
