Communities across the United States are collaborating to create a coordinated response to intimate partner violence (IPV); ideally, this involves promoting best practices in the justice and human service systems and engaging a broad array of community sectors (e.g., human service; criminal justice; faith; business; education) to promote victim safety and batterer accountability (Pence, 1999). The current study examined the extent to which Family Violence Coordinating Councils resulted in change in the systems’ response to IPV. Specifically, we examined judicial order of protection data from 1990 to 2005 to establish whether the formation and development of councils across the state of Illinois promoted the issuance of plenary orders of protection following the initial granting of emergency orders of protection. Such a pattern would indicate implementation of a best practice in the system response to IPV. Utilizing a multilevel logistic modeling approach, we found that the introduction and development of councils was indeed related to the accessibility of plenary orders of protection. The specific ways in which councils may have influenced such an outcome and the implications of this approach for research on council effectiveness are discussed.  相似文献

This study explored the influence of participation, gender and organizational sense of community (SOC) on both the intrapersonal and interactional components of psychological empowerment (PE). Participants were residents (n = 562) involved in community organizing efforts in five U.S. communities. Measures of participation and SOC were tailored to community organization contexts. SOC assessed three dimensions: (1) connection of members to the organization; (2) perceptions about the organization as a bridge to other groups and organizations in the broader community; and (3) bond or attachment to the community at large. Income (low, middle and high-income) was tested as a moderator of these relationships. Results showed significant moderating effects of income on the relationship between participation, gender and SOC on both components of PE. Participation was positively related with intrapersonal empowerment across income levels, but positively related with interactional empowerment only for low-income individuals. Gender was only associated with intrapersonal empowerment, and only for low-income individuals. SOC, as expressed through bridging to the broader community, was positively related with interactional PE for all income levels, but with intrapersonal PE for only low and middle-income individuals. In contrast, member connection to the organization was not related to interactional empowerment and significantly related to intrapersonal empowerment only for individuals with higher income. The importance of participation, gender and SOC for different types of empowerment and the impact of income on the SOC-empowerment relationship are discussed.  相似文献

This study aimed to describe the course of early onset eating disorders in a population-based sample followed from 14 to 20 years; identify variables that could account for the persistence of eating disorders from 14 to 20 years; and describe outcome of early onset eating disorders with reference to general and psychological functioning at age 20. Participants (N?=?1,383; 49 % male) were drawn from the Western Australian Pregnancy Cohort (Raine) Study, which has followed children from pre-birth to young adulthood. Eating disorder symptoms were assessed using an adapted version of the Eating Disorder Examination-Questionnaire, at ages 14, 17 and 20. At age 14, 70 participants met DSM-IV criteria for a binge eating or purging eating disorder. Nearly half (44 %) of these adolescents ceased to meet criteria for an eating disorders at ages 17 and 20, whilst one-quarter still met criteria for an eating disorder at age 20 and one-fifth met criteria for an eating disorder at all three time points. Purging at age 17 and externalising behaviour problems at age 14 were the strongest predictors of eating disorder persistence to age 20. Participants who experienced a persistent eating disorder were less likely to complete high school than other participants, and reported pronounced depressive and anxiety symptoms at age 20. This study provides new data the course and outcome of early onset eating disorders at a population level. Behavioural difficulties in early adolescence and purging in middle adolescence may predict persistent eating pathology to young adulthood.  相似文献

Skilled individuals demonstrate a spatially localized or relatively lower response in brain activity characterized as neural efficiency when performing within their domain of expertise. Elite athletes are experts in their chosen sport and thus must be not only adept in the motor domain but must be resilient to performing under the stress of high-level competition. Such stability of performance suggests this population processes emotion and mental stress in an adaptive and efficient manner. This study sought to determine if athletes with a history of successful performance under circumstances of mental stress demonstrate neural efficiency during affective challenges compared to age-matched controls. Using functional magnetic resonance imaging, the blood-oxygen level–dependent response was recorded during emotional challenge induced by sport-specific and general unpleasant images. The athletes demonstrated neural efficiency in brain regions critical to emotion regulation (prefrontal cortex) and affect (insula) independently of their domain of expertise, suggesting adaptive processing of negative events and less emotional reactivity to unpleasant stimuli.  相似文献

The purpose of this study was to investigate potential qualitative differences in relative timing across age both within and across speed conditions. Forty right-handed males performed 48 trials of a five-component coincident-timing task at one speed and then 16 more at a different speed. The independent variables were age (5-7, 8-10, 11-13 years, and adult), speed (slow and fast), and block order (training and transfer). The results indicated that within-speed relative timing consistency improved with increasing age for movement-time and pause-time components, while a cross-speed transfer improved with age only for pause time. Movement velocity emerged as a more stable timing parameter than movement time across speeds for all groups. The last movement-time component correlated highly with the total response times, suggesting that coincident-timing accuracy was controlled to a large degree by a final, fine-tuning correction. These results imply that developmental deficits in relative timing increase the attention demands of a given task, thereby reducing a child’s capacity to concurrently control his movements and monitor events in the environment.  相似文献

The election of President Barack Obama offers a unique opportunity to test the impressionable‐years hypothesis—the theory of political socialization that predicts that widely experienced political events can have a lasting impact on the political attitudes of individuals who experience that event in their youth, thereby creating a generational distinction. Using data from an original survey embedded in the 2010 Cooperative Congressional Election Study, we examine the racial attitudes of White youth who came of age during Barack Obama's presidential campaign and election to see if those individuals are significantly more liberal on racial attitudes than older generations of Whites. In other words, we look for early evidence that an “Obama generation” has emerged. We find there are indeed early signs of a generational distinction. Members of the “Obama generation” are more strongly opposed to racial resentment, but they exhibit similar levels of opposition to old‐fashioned racism as older cohorts. Additionally, we uncover that the factors that traditionally structure racial attitudes among Whites, most notably contact, education, and residential proximity, work quite differently for members of this generation. We take these findings as initial evidence that Barack Obama's presidency will have a lasting impact on the racial views of a generation of Americans.  相似文献

Abstract : In this article I propose that empire be countered by a revised understanding of eschatology. I first explore the idea of an eschatology of space, wherein the notion of eschatos as limit is advanced. I then revisit a temporal understanding of eschatology illumining the theme of the pause, or rest. This Sabbath theme, in concert with attentiveness to space, is then brought to bear upon the primal North American experience of empire: the expropriation of aboriginal lands.  相似文献

Three participants whose problem behavior was maintained by contingent attention were exposed to 45‐min presessions in which attention was withheld, provided on a fixed‐time (FT) 15‐s schedule, or provided on an FT 120‐s schedule. Following each presession, participants were then tested in a 15‐min session similar to the social attention condition of an analogue functional analysis. The results showed establishing operation conditions increased problem behavior during tests and that abolishing operation conditions decreased problem behavior during tests.  相似文献

Using longitudinal student data from 15 four-year (n = 3,072) and 13 (n = 788) two-year postsecondary institutions, the authors tested the effects of interest-major congruence, motivation, and 1st-year academic performance on timely degree completion. Findings suggest that interest-major congruence has a direct effect on timely degree completion at both institutional settings and that motivation has indirect effects (via 1st-year academic performance). The total effects of both interest-major congruence and motivation on timely degree completion underscore the importance of both constructs in understanding student adjustment and postsecondary success. Implications for theory and counseling practice are discussed.  相似文献

This article conceptually links theory and research on volunteerism to different forms of political activity, specifically activism and civic engagement. Multiple perspectives and measures of personality as antecedents of volunteerism, activism, and civic engagement are outlined, including individual differences in motivations, interpersonal orientations, and traits. Next, self-report data from 624 people involved in AIDS service organizations (as clients, volunteers, staff, or supporters) are utilized to empirically explore the best personality predictors of AIDS activism and civic engagement. Other-focused rather than self-focused motivation better predicted AIDS activism and civic engagement. The only measure of interpersonal orientation consistently related to these outcomes was communal orientation; as well, only the trait of extraversion was related to both outcomes. In analyses testing the predictive power of constellations of personality measures, other-focused motivation better predicted AIDS activism and civic engagement than the other measures of motivation, interpersonal orientation, and traits. Finally, meditational analyses supported a developmental sequence in which other-focused motivation leads to specific activism, which, in turn, encourages broader civic engagement. The discussion focuses on theoretical implications for understanding the impact of personality on different forms of citizenship behaviors and of the applicability of the Volunteer Process Model for studying political activity and civic engagement.  相似文献
