The study sought to better understand the cultural contexts of the risks for adolescent females who have dropped out of school. Focus groups were conducted with 37 Black and Coloured females aged 13 to 17 in Cape Town, South Africa. Data were analysed using content analysis. Methamphetamine, cannabis, and alcohol were used by both, however, Black teens also used methaqualone and Coloured teens used heroin and ecstasy. Some teens traded sex for drugs and others did so at the request of their drug-addicted mothers. Teens revealed high rates of violence, including rape, and many myths and barriers about condom use, revealing risky sex behaviours. Conclusion—Cultural nuances between the two groups will help inform the adaptation of an HIV prevention intervention.  相似文献

This study represents the first step toward systematic behavioral treatment development and pilot testing of a novel approach to smoking cessation that utilizes adults interested in helping someone to stop smoking (i.e., support persons) as the agent of change. The counselor manual for a telephone-based intervention for support persons was developed based on a previous clinic-based intervention. Social cognitive theory served as the conceptual basis for the intervention. Ten adult non-smoking females completed the treatment protocol, consisting of six 20 - 30-min sessions and written materials. The support person was the sole recipient of the professional intervention. Feedback was obtained from 8 of the 10 participants and all 4 telephone counselors 1 week post-treatment (week 10). Results indicate that the telephone-based intervention was feasible and acceptable to participants. The intervention was refined based on participant and counselor feedback and will be subsequently tested in a randomized pilot trial.  相似文献

Although women have made progress in entering scientific careers in biology, they remain underrepresented in mathematically intensive fields such as physics. We investigated whether gender differences in mathematics motivation and socialisers’ perceptions impacted choices for diverse STEM careers of varying mathematical intensity. Drawing on expectancy-value theory, we tested structural equation models in which adolescents’ preferred careers related to each of physics, biology, chemistry, and mathematics were predicted by prior mathematical performance, motivations, and mothers’ perceptions. We explored potential differences in gendered processes of influence using multigroup models. Samples were 331 Australian adolescents followed from 9th to 11th grade in 1998 and 277 U.S. adolescents from 9th to 12th grade in 2009–10. In both samples female adolescents preferred biological careers more than males did; male adolescents preferred physics-related careers and also mathematical careers in the Australian sample. Mothers’ perceptions were important to female and male adolescents’ mathematics motivations; gendered motivations were more evident in the Australian sample. Mathematics interest played the strongest role in male adolescents’ preferred careers, whereas actual or perceived mathematical achievements were most important for females, demonstrating the impacts of mathematical motivations on preferences for diverse STEM careers.  相似文献

Animal models of conflict behavior predict that an organism's behavior in a conflict situation is influenced by physical characteristics related to abilities to impose costs on adversaries. Stronger and larger organisms should be more motivated to seek larger shares of resources and higher places in hierarchies. Previous studies of human males have suggested that measures of upper‐body strength are associated with measures of support for inequality including Social Dominance Orientation (SDO), a measure of individual differences in support for group‐based hierarchies. However, other studies have failed to replicate this association. In this article, we reexamine the link between upper‐body strength and support for inequality using 12 different samples from multiple countries in which relevant measures were available. These samples include student and locally representative samples with direct measures of physical strength and nationally representative samples with self‐reported measures related to muscularity. While the predicted correlation does not replicate for every single available measure of support for inequality, the overall data pattern strongly suggests that for males, but not females, upper‐body strength correlates positively with support for inequality.  相似文献

In two experiments, we examined the influence of situation-evoking stimuli on the resolution of lexical ambiguity. In Experiment 1, we examined situation-evoking stimuli at an early NP position. Readers were asked to establish whether specific entities were likely to participate as agents in contextually defined situations. Naming latencies demonstrated that defined situations headed by likely agents evoked a domain of reference that included only the situation-appropriate meaning of a targeted lexical ambiguity. In contrast, defined situations headed by unlikely agents evoked a domain of reference that did not include either meaning of the intended ambiguous word. In Experiment 2, we examined situation-evoking stimuli at a later direct object position. The specificity of the theme/patient role filler was manipulated, where the linguistic expressions were either specific or general with respect to a given contextual situation. The results showed that contexts with specific situation-evoking stimuli were rated as strongly biased and provided a domain of reference for the immediate resolution of lexical ambiguity, whereas contexts with nonspecific role fillers were rated as ambiguous and provided a domain of reference that was supportive of both meanings of an ambiguous word. The results were discussed within a contextual-feature-sensitive model of language processing.  相似文献

In recent years there have been a number of advances in understanding of predisposing and protective factors in the development of cerebral palsy in infants. Multiple gestation births, maternal infection, and maternal and fetal thrombophilic conditions all predispose to the development of CP in the infant. Opportunities for prevention of CP may develop from an improved understanding of these factors and their mechanisms of operation. Similar progress has been made in the evaluation of treatments for CP and the effects of these treatments on the individual's impairment, function, and disability. Selective posterior rhizotomy and Botulinum toxin A are now widely used in the treatment of spasticity. The challenge remains to determine how effectively these promising interventions can alter long-term function and quality of life outcomes in children and adults with CP.  相似文献

In the business context, there is a broad spectrum of practices that potentially harm others, yet might benefit the organization. We examined the influence of individual and situational differences in predicting (un)ethical behavior in these moral gray zones using an in‐basket exercise that included covert moral issues in which managers could give unethical instructions to their followers. Results show that individual differences in moral disengagement directly predicted unethical behavior and functioned as a mediator of the relationship between authenticity and unethical behavior. Furthermore, effects differed in weak compared to strong situations. Study 2, replicated the results from Study 1, developed a direct test of the situational strength hypothesis, and showed that high versus low situation strength moderated the relation of moral disengagement to unethical behavior.  相似文献

This study tests three hypotheses derived from Berger's (1967) plausibility theory. The first hypothesis states that among people who attend church frequently, education's liberalizing effect on attitudes toward elective abortion is weakest among conservative Protestants and Catholics, intermediate among moderate Protestants, and strongest among liberal Protestants and Jews. Hypotheses 2 states that education's effect is weaker among frequent than infrequent attenders in all religious groups except liberal Protestants and Jews, and Hypothesis 3 states that education's effect does not vary by religious group among infrequent attenders. Using General Social Survey data, I found strong support for Hypotheses 1 and 2 and partial support for Hypothesis 3. I discuss the implications of the findings for plausibility theory.  相似文献
