Measures of head injury, executive functioning, and intelligence were given to a community sample composed of 102 male perpetrators of intimate partner aggression (IPA) and 62 nonaggressive men. A history of head injury and lower mean score on a measure of verbal intelligence were associated with the frequency of male-perpetrated physical IPA as reported by male perpetrators and their female partners. Lower mean scores on a measure of verbal intelligence also predicted frequency of psychological IPA perpetration. Using the perpetrator subtypes outlined by Holtzworth-Munroe et al. (2000), analyses revealed that compared with other groups, the most severely aggressive subtypes (i.e., borderline-dysphoric and generally violent-antisocial) were the most likely to report a history of head injury and to have significantly lower mean scores on a neuropsychological test of verbal intelligence. The possible role of neuropsychological factors in IPA perpetration and implications for prevention and intervention programs are discussed. 相似文献

This paper explores the current status of professionalization of communication management practice which emerged from a content analysis of 360 responses to questions exploring the nature of practitioner identity (or dis-identity) with communication management. The results revealed that positive identification arose from an ability to influence, emulate the professional values of peers, and cohesion with the wider practitioner community. Conversely, dis-identification arose from the poor performance of colleagues, advice not being taken, and media ‘spin’. 相似文献

Weatherly JN Miller JC Montes KS Rost C 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2012,28(2):217-223
Dixon and Johnson (Anal Gambl Behav 1: 44–49, 2007) proposed the Gambling Functional Assessment as a tool to identify the consequences maintaining the respondent’s gambling
behavior, but subsequent studies on its psychometric properties suggested that it could use improvement. The present study
investigated the internal consistency of the Gambling Functional Assessment—Revised using the responses of 1,060 undergraduate
students. Temporal reliability was assessed by a second administration of the measure four (n = 87) or twelve (n = 98) weeks after the first administration. Temporal reliability was also compared to the South Oaks Gambling Screen (Lesieur
and Blume in Am J Psychiatry 144: 1184–1188, 1987), which was also administered at both time points. Internal consistency measures were good to excellent, even when potential
non-gamblers were excluded from the analyses. Temporal stability was also very good, with the possible exception of the consequence
of “escape” at 12 weeks. The Gambling Functional Assessment—Revised represents a potentially useful tool for researchers and
therapists interested in why respondents are gambling. 相似文献

Classical continuous goodness-of-fit (GOF) testing is employed for examining whether the data come from an assumed parametric model. In many cases, GOF tests assume a uniform null distribution and examine extreme values of the order statistics of the samples. Many of these statistics can be expressed by a function of the order statistics and the p-values amount to a joint probability statement based on the uniform order statistics. In this paper, we utilize Steck''s recursion method and propose two high precision computing algorithms to compute the p-values for these GOF statistics. The numerical difficulties in implementing Steck''s method are discussed and compared with solutions provided in high precision libraries. 相似文献

DYNAMIC TREATMENT EFFECTS OF TEACHER'S AIDES IN AN EXPERIMENT WITH MULTIPLE RANDOMIZATIONS

Using data from a large‐scale two‐stage experiment wherein students and teachers were randomized at both kindergarten entry and first grade to be sorted into classes either with or without full‐time teacher's aides, I estimate an econometric model that is uniquely suited to take advantage of this design to determine their effect on academic achievement. The identification strategy produces fully nonparametric dynamic average treatment effects for every treatment path. I find that the use of full‐time teacher's aides increases student achievement, but the benefits appear to accrue mostly to those of higher socioeconomic status and to White students. A cost‐benefit analysis shows that full‐time teacher's aides may be a competitive alternative to class size reductions in terms of net social benefits. (JEL I21, I28) 相似文献

Understanding how people view flash flood risks can help improve risk communication, ultimately improving outcomes. This article analyzes data from 26 mental models interviews about flash floods with members of the public in Boulder, Colorado, to understand their perspectives on flash flood risks and mitigation. The analysis includes a comparison between public and professional perspectives by referencing a companion mental models study of Boulder‐area professionals. A mental models approach can help to diagnose what people already know about flash flood risks and responses, as well as any critical gaps in their knowledge that might be addressed through improved risk communication. A few public interviewees mentioned most of the key concepts discussed by professionals as important for flash flood warning decision making. However, most interviewees exhibited some incomplete understandings and misconceptions about aspects of flash flood development and exposure, effects, or mitigation that may lead to ineffective warning decisions when a flash flood threatens. These include important misunderstandings about the rapid evolution of flash floods, the speed of water in flash floods, the locations and times that pose the greatest flash flood risk in Boulder, the value of situational awareness and environmental cues, and the most appropriate responses when a flash flood threatens. The findings point to recommendations for ways to improve risk communication, over the long term and when an event threatens, to help people quickly recognize and understand threats, obtain needed information, and make informed decisions in complex, rapidly evolving extreme weather events such as flash floods. 相似文献

THE IMPACT OF SCHOOL RACIAL COMPOSITIONS ON NEIGHBORHOOD RACIAL COMPOSITIONS: EVIDENCE FROM SCHOOL REDISTRICTING

I use data surrounding public school redistricting to study how school racial compositions affect neighborhood racial compositions. This redistricting followed from the end of court‐ordered busing for racial desegregation, significantly changing the racial composition of the assigned school for many neighborhoods. Over a 5‐year period, the impact of an increase in the percent black of the assigned elementary school on the percent black of the neighborhood was positive. The effects increased over time, consistent with a simple model of short‐run neighborhood racial dynamics. These results have implications for potential effects of school racial desegregation policy changes on neighborhood racial compositions. (JEL H75, I28, R23) 相似文献
