Incomplete moments are used to characterize income inequality and provide the basis for interdistributional Lorenz curves. Four measures of interdistributional inequality are considered and seen to be related to an interdistributional welfare interpretation. Based upon these measures, there has been a significant secular decline in interdistributional inequality between blacks and whites over the past 30 years.  相似文献

Abstract

Objective: To investigate the motivational factors and the barriers to physical activity (PA) in traditional college students (TS) and nontraditional college students (NTS) and determine if differences exist between these 2 groups. Participants: A total of 746 college students; 628 were TS (19.1 ± 1.2 years), and 118 were NTS (31.2 ± 8.6 years). Methods: In fall 2010, students voluntarily completed a demographic questionnaire, Barriers to Being Active Quiz, and Exercise Motivations Inventory–2 (EMI-2). Results: EMI-2 revealed that TS and NTS differed on 8 of the 14 motivational factors for exercise. There was a significant difference between TS and NTS for the following barriers: fear of injury (p = .001), lack of resources (p = .017), and lack of skill (p = .003). Conclusion: Based on these findings, interventions can be developed for the varied needs of a diverse student population as it pertains to PA participation.  相似文献

ABSTRACT

The purposes of this paper are to abstract from a number of articles variance component estimation procedures which can be used for completely random balanced incomplete block designs, to develop an iterated least squares (ITLS) computing algorithm for calculating maximum likelihood estimates, and to compare these procedures by use of simulated experiments. Based on the simulated experiments, the estimated mean square errors of the ITLS estimates are generally less than*those for previously proposed analysis of variance and symmetric sums estimators.  相似文献

The sociology of aging draws on a broad array of theoretical perspectives from several disciplines, but rarely has it developed its own. We build on past work to advance and empirically test a model of mental health framed in terms of structural theorizing and situated within the life course perspective. Whereas most prior research has been based on cross-sectional data, we utilize four waves of data from a nationally representative sample of American adults (Americans' Changing Lives Study) collected prospectively over a 15-year period and find that education, employment and marital status, as well as their consequences for income and health, effectively explain the increase in depressive symptoms after age 65. We also found significant cohort differences in age trajectories of mental health that were partly explained by historical increases in education. We demonstrate that a purely structural theory can take us far in explaining later life mental health.  相似文献

A pilot study using a prospective design examined the impact of a collaboratively developed training model, called the Parent Empowerment Program (PEP), for professionally-employed family peer advocates who work with caregivers of children with mental health needs. This training used a combination of didactic, practice exercises, and group discussion. It targeted specific mental health knowledge content and collaborative skills to facilitate the work of family peer advocates in empowering caregivers. Co-delivered by a family peer advocate and clinician, the training consisted of a 40-hour face-to-face training, followed by six monthly face-to-face booster sessions. A total of 15 advocates participated in assessments conducted at baseline and post-training. This group of experienced family peer advocates showed no significant increase in knowledge about mental health content, but post-training assessments indicated increased collaborative skills and mental health services self-efficacy. This initial evaluation has implications for expanding training and support for the emergent workforce of professionally-employed family peer advocates in children's mental health.  相似文献

Police and scholars note that successful crime fighting requires police and residents to “co‐produce” public safety. However, residents are often reluctant to get involved in policing initiatives or even report crimes they witness. One possible means of stimulating resident involvement in crime‐control activities is through neighborhood organizations. This research, conducted on 1,313 residents of 42 neighborhoods in western South Carolina, investigates whether neighborhood organization participation increases the likelihood of assisting police in crime‐control efforts. Results indicate that organization participants are more likely to assist police than are nonparticipants, even after controlling for social cohesion, perceptions of police legitimacy, various policing strategies, fear of crime, and demographic factors.  相似文献

A substantial portion of gamblers in treatment may have co-occurring mental health disorders including substance use disorders, especially alcohol dependency, personality disorders, affective disorders, anxiety disorders and impulse control disorders. Co-occurring mental health disorders affect treatment seeking, the treatment process and its outcome, quality of life and functioning in many mental health disorders. Participants in this study were 78 adults enrolled in state-supported out-patient services for pathological gambling and current Gamblers Anonymous attendees. The majority of participants (76.6%) had co-occurring behaviours; 55.8% had multiple co-occurring behaviours. Participants with multiple co-occurring behaviours were more likely to report that a co-occurring behaviour increased the severity of their gambling symptoms. A dose/response relationship between number of co-occurring behaviours and severity of gambling problems was found. Co-occurring behaviours can interact with gambling behaviour. Brief, validated screening instruments are available for screening and diagnosing co-occurring behaviours among gamblers presenting for treatment.  相似文献
