Risk assessment tools driven by algorithms offer promising advantages in predicting the recidivism risk of defendants. Jurisdictions are increasingly relying upon risk tool outcomes to help judges at sentencing with their decisions on whether to incarcerate or whether to use community-based sanctions. Yet as sentencing has significant consequences for public safety and individual rights, care must be taken that the tools relied upon are appropriate for the task. Judges are encouraged to act as gatekeepers to evaluate whether the forensic risk assessment tool offered has a sufficient level of validity in that it is fit for the purposes of sentencing, provides an acceptable level of accuracy in its predictions, and achieves an adequate standard of reliability with regard to its outcomes. 相似文献

Gender-role conflict theory has suggested that women athletes will experience role conflict because they are attempting to enact both feminine and masculine gender roles, yet research findings have shown mixed support for this notion. The purpose of this study was to explore how women rugby players negotiate gender-role expectations and conflict as women participating in a traditionally masculine sport. Eleven Caucasian women, noncollege rugby players between the ages of 25 and 38 were interviewed. The results indicated that women rugby players perceived numerous discrepant gender-role expectations. In addition, three different types of gender-role conflict emerged; however, similar to previous findings, participants perceived conflicting expectations for their gender-role behavior more than they seemed to experience conflict about those expectations. Participants actively employed various strategies to resolve or avoid experiencing gender-role conflict. The resiliency displayed by the women athletes in coping with discrepant gender-role messages provides new considerations for gender-role conflict theory. 相似文献

How do stimulus size and item number relate to the magnitude and direction of error on center estimation and line cancellation tests? How might this relationship inform theories concerning spatial neglect? These questions were addressed by testing twenty patients with right hemisphere lesions, eleven with left hemisphere lesions and eleven normal control subjects on multiple versions of center estimation and line cancellation tests. Patients who made large errors on these tests also demonstrated an optimal or pivotal stimulus value, i.e., a particular size center estimation test or number of lines on cancellation that either minimized error magnitude relative to other size stimuli (optimal) or marked the boundary between normal and abnormal performance (pivotal). Patients with right hemisphere lesions made increasingly greater errors on the center estimation test as stimuli were both larger and smaller than the optimal value, whereas those with left hemisphere lesions made greater errors as stimuli were smaller than a pivotal value. In normal subjects, the direction of errors on center estimation stimuli shifted from the right of true center to the left as stimuli decreased in size (i.e., the crossover effect). Right hemisphere lesions exaggerated this effect, whereas left hemisphere lesions diminished and possibly reversed the direction of crossover. Error direction did not change as a function of stimulus value on cancellation tests. The demonstration of optimal and pivotal stimulus values indicates that performances on center estimation and cancellation tests in neglect are only relative to the stimuli used. In light of other studies, our findings indicate that patients with spatial neglect grossly overestimate the size of small stimuli and underestimate the size of large stimuli, that crossover represents an “apparent” shift in error direction that actually results from normally occurring errors in size perception, and that the left hemisphere is specialized for one aspect of size estimation, whereas the right performs dual roles. 相似文献

The present study examined the degree to which parenting attitudes and behavior (i.e., self-reported warmth, restrictiveness, and behavioral sensitivity as assessed during a freeplay session) were related to toddlers' development. Results showed a restrictive attitude was negatively related to social and cognitive development, whereas paternal sensitivity was positively related to aspects of social development that are less dependent on language skills (e.g., motor and daily living skills). Fathers of girls exhibited greater sensitivity in their freeplay interactions than fathers of boys. More globally, the present research demonstrates important relations between the parenting attitudes and behavior of low- to working-income African-American fathers and young children's development, and similarities to White, middle-income fathers. 相似文献

In an attempt to control gastric acid secretion with operant-conditioning techniques, four normal women were given visual feedback on gastric pH plus money reinforcers. When money was made dependent on increased secretion in a differential-reinforcement-of-high-rates schedule, the rate of secretion of three of the four subjects increased to three times baseline. When money was then made dependent on decreased secretion in a differential-reinforcement-of-other-behaviors schedule, the rate of secretion of these three subjects returned to baseline levels. Heart rate, respiratory frequency, abdominal electromyographic activity, and stomach motility (measured by the electrogastrogram method) were not consistently correlated with acid secretion across subjects, although individual subjects showed substantial correlations between acid secretion and one or more other physiological response. 相似文献

This study examines how religion's impact on Americans’ attitudes toward same‐sex practices varies by the type of practice being considered. We theorize that same‐sex romantic and family practices such as sexual relations, marriage, and adoption represent distinct practice types, differing in degrees of legality, cultural legitimacy, and in their internal power dynamics. Consequently, we expect that Americans view each practice type somewhat differently and their opinions on each may be influenced by religion in distinctive ways. Drawing upon national‐level data, we estimate and compare the relative net effects of a comprehensive battery of religious measures on support for gay sex, marriage, and adoption, both for the full sample and across religious traditions. Analyses demonstrate that public opinion toward gay sexual relations is more strongly related to religious practice and theological conservatism compared to attitudes regarding same‐sex marriage or adoption. Moreover, frequent religious practice and conservative theological beliefs about the Bible tend to be more strongly associated with attitudes toward same‐sex relationships for evangelicals, compared to mainline Protestants and, to a lesser extent, Catholics. Findings ultimately affirm that the type of same‐sex practice being considered (sex, marriage, or adoption) serves to moderate religions’ impact on Americans’ support for such practices. 相似文献

Various aspects of parental work schedules affect the opportunities and constraints that parents encounter when arranging care for their children. This study examined the extent to which the combination of couples’ work schedules was associated with their use of different types of child care, focusing on parental, formal, and informal child care. We considered multiple dimensions of couples’ work schedules, namely, the timing of work, schedule flexibility, and home-based telework. Data from a recent Dutch survey were used, including information about 1599 dual-earner couples with children aged 0–6 years. The results indicated that paid work during nonstandard hours increased the amount of parental child care that was provided by one parent while the other parent was working, whereas work during evenings, nights, and weekends decreased the likelihood of using both formal and informal child care. Results further revealed gender differences for nonstandard hours and schedule flexibility. We found stronger effects of mothers’ work schedules, indicating that a gender-neutral approach to parental work is not justified. These results indicate that the timing of parental work is important to consider when examining not only parental child care but also formal and informal child-care use. We provide recommendations for future research, specifically regarding the possible consequences for parental well-being. 相似文献

The purpose of this study was to determine the prevalence and individual risk factors of people who trade or sell sex among sexually active individuals seeking HIV and sexually transmitted infection (STI) testing. Using electronic agency records, an analysis of the characteristics of 5,029 youth and adults who voluntarily obtained HIV and STI testing was conducted. Multiple imputation procedures for missing data from 3 variables and logistic regression were conducted. A total of 128 individuals reported having traded sex. Nine variables had statistically significant associations with trading sex. Individuals who identified as White and female had lesser odds of trading sex, whereas individuals who were transgender, were living in a shelter, had been sexually assaulted, had a previous STI, had high-risk sex, or used drugs had greater odds of trading sex. Elevated levels of high-risk behavior in addition to sexual trauma should be considered in intervention research and community health practice. Implications for service providers and researchers are discussed. 相似文献

In the 1980s and early 1990s, more than 50,000 Iranian refugees moved to Sweden. The Swedish state attended to their immediate needs, providing housing, language training, and other types of support. Moreover, these migrants had almost immediate access to all the benefits of the Swedish welfare state including affordable healthcare, unemployment insurance, and free education up to and including the tertiary level. Despite the opportunities available to them in Sweden, many Iranian refugees have faced challenges, especially when trying to secure meaningful work. One of the strategies they have used to overcome barriers to entering the labor market is to leave Sweden for onward destinations which are seen as having relatively more to offer. This study explores the onward migration of Iranians from Sweden by way of a two-step mixed methods approach: in the first step, population register data is used to determine how onward migrants differ from those Iranians who stay in Sweden. In the second step, information from life history interviews conducted with onward migrants in London and Toronto is used to understand what motivates individuals to leave Sweden. Overall, the study finds that highly educated Iranians who have struggled to find employment in Sweden are the most likely to move on. Their precise motivations for doing so, however, are nuanced and complex and relate to more than just economic factors. 相似文献
