In this article, the authors explore the applications of focus groups to rehabilitation and disability research. Key issues in designing focus group research (e.g., methodological considerations, strategies for conducting focus groups, data analysis procedures) are highlighted. The authors then discuss specific considerations for conducting focus groups with people with disabilities. The article concludes with a review of three research studies in rehabilitation that used a focus group methodology. 相似文献

This paper describes research regarding factors predicting career optimism for a group of postsecondary students with disabilities (N = 208) who were enrolled in seven colleges and universities in four states. Career optimism was defined as a student's self-confidence regarding his or her ability to choose, maintain, and advance in an appropriate career. The proposed model incorporated variables related to employment discrimination and disincentives such as perceived impact of disability on one's education and quality of life, racial/ethnic status, gender, and presence of disability benefits. Results indicated that two aspects of "disadvantagement," specifically severity of perceived impact of disability and racial/ethnic status, were significant predictors of career optimism. Implications of the findings were discussed in terms of informational interventions, curricula, development of self-advocacy and self-determination, and research topics. 相似文献

Maternal biological systems impact infant temperament as early as the prenatal period, though the mechanisms of this association are unknown. Using a prospective, longitudinal design, we found that maternal (N = 89) amplitudes of the late positive potential (LPP) in response to negative stimuli during the second, but not the third, trimester of pregnancy predicted observed and physiological indices of temperamental reactivity in infants at age 4 months. Maternal LPP was positively associated with observed infant fear and negatively associated with frontal EEG asymmetry and cortisol reactivity in infants at age 4 months. Results identify a putative mechanism, early in pregnancy, for the intergenerational transmission of emotional reactivity from mother to infant. 相似文献

Symptoms of attention‐deficit/hyperactivity disorder (ADHD) and anxiety are common during adolescence and frequently co‐occur. However, the genetic and environmental influences that underlie this co‐occurrence are understudied. Using a large twin sample (N = 1,017), we examined cross‐sectional genetic and environmental influences on ADHD and anxiety symptoms during childhood. We also explored whether these influences were shared with attentional control, a putative mechanism for symptom comorbidity. We found evidence for common genetic and nonshared environmental influences on the covariation among attentional control, ADHD, and anxiety symptoms, supporting the putative role of attentional control as a mechanism by which comorbid problems may develop. Genetic factors also accounted for symptom co‐occurrence after controlling for covariation with attentional control, suggesting the presence of additional unmeasured mechanisms. 相似文献

Research and opinion polls demonstrate that attitudes toward same-gender parent families have been improving in recent years among Western countries; however, the history of oppression toward, and misconceptions about, same-gender parent families continue to be demonstrated in Australian family rights policies. Common misconceptions include the belief that children need both male and female role models, and this could be influencing peoples’ support for same-gender family rights and having a wider impact on legislation change. Yet a dearth of research exists exploring a connection between gender role beliefs and support for same-gender family rights using a broad international sample, including Australia. To investigate this connection, a sample (N = 615) from 18 English-speaking countries responded to a series of questions to determine the importance of gender norm beliefs on same-gender family prejudice. Regression analysis demonstrated that people with traditional beliefs about gender norms were more likely to endorse a negative attitude toward same-gender marriage and same-gender parenting. Findings suggest a link between socially prescribed gender norms and prejudice toward same-gender parent families that may be fueling arguments against same-gender family rights policies. The implications of these findings on same-gender parent families and their rights require future investigation. 相似文献

The calculation of reorder points when the distribution of lead-time demand is normal is quite complex, primarily because of having to bound it away from negative demand values. A number of researchers have sought feasible alternative forms of lead-time demand which can be calculated without undue difficulty. It is proposed here to assume a Poisson (daily) demand and an exponential lead time (days). If they are assumed independent their convolution is geometric, which is itself asymptotically exponential. This has a number of advantages: (1) The exponential lead time is appropriate where the lead time is often short (i.e., local source), occasionally longer (when the local sources stock out), and, infrequently, quite long. (2) The geometric lead-time demand is independent of changes of time scale. (3) Reorder points and lot sizes appear in simple closed form. (4) The exponential asymptote is sufficiently close that this further simplification is usually warranted. 相似文献

The Risk Amplification and Abatement Model (RAAM) demonstrates that negative contact with socializing agents amplify risk, while positive contact abates risk for homeless adolescents. To test this model, the likelihood of exiting homelessness and returning to familial housing at 2 years and stably exiting over time are examined with longitudinal data collected from 183 newly homeless adolescents followed over 2 years in Los Angeles, CA. In support of RAAM, unadjusted odds of exiting at 2 years and stably exiting over 2 years revealed that engagement with prosocial peers, maternal social support, and continued school attendance all promoted exiting behaviors. Simultaneously, exposure to family violence and reliance on shelter services discouraged stably exiting behaviors. Implications for family‐based interventions are proposed. 相似文献

Understanding the impact of EGM Jackpots on gambling intensity may allow targeted strategies to be implemented that facilitate harm minimisation by acting to reduce losses of gamblers who play frequently, while maintaining the enjoyment and excitement of potential jackpots. The current study investigated the influences of Hidden and Mystery Jackpots on EGM gambling intensity. In a Hidden Jackpot, the prize value is not shown to the player, although the existence of a jackpot prize is advertised. In a Mystery Jackpot, the jackpot triggering state of the machine is unknown to players. One hundred and seven volunteers (males = 49, females = 58) played a laptop-simulated EGM with a starting $20 real-money stake and a chance to win a Jackpot ($500). Participants played for either a Hidden or Known Jackpot Value, with either a Mystery or Known winning symbol combination in a crossed design. Lastly, a control condition with no jackpot was included. Gambling intensity (speed of bets, persistence) was greater when the Jackpot value was unknown, especially when a winning-symbol combination suggested that a win was possible. While there is no evidence in the present investigation to suggest that Hidden or Mystery jackpots contribute to greater player enjoyment, there is some evidence to suggest a marginal positive contribution of hidden jackpots to risky playing behaviour. 相似文献

This is the first in a set of papers to revisit Henry Abelove’s “Freud, Male Homosexuality, and the Americans” (1985–1986) 30 years after initial publication. By way of introduction I describe the social and academic context of the early 1980s and Dr. Abelove’s search to find a receptive audience. For those unfamiliar with the work I briefly outline some important arguments made by Dr. Abelove and reflect on the changing social environment—politically, socially, and within psychoanalytic thought—since initial publication. With my colleagues Dr. Cushman and Dr. Layton, we reflect on Dr. Abelove’s scholarship and prescience and pause to give it the belated recognition from psychoanalysis that it has long deserved. 相似文献
