Alcohol use is related to child physical abuse, although little is known about gender-specific risks factors. This study examines the relationships between alcohol outlets, context-specific drinking, dose–response drinking and child physical abuse for mothers and fathers. Telephone interviews were conducted with 1973 female and 1050 male respondents in 50 California cities. Weighted negative binomial models were used to calculate the frequency of physical abuse in the past year. Drinking more often at restaurants was related to higher frequency of physical abuse for fathers, while mothers who drank more frequently at bars and parties used physical abuse more often. There were no significant dose–response drinking relationships for fathers. Drinking higher amounts at bars, parties, and restaurants was associated with less frequent physical abuse for mothers. Our findings suggest that a focus on drinking contexts may reveal heightened risk for many mothers who do not consume large amounts of alcohol. 相似文献

Recent national events have brought the issue of police-community relations into the public eye. Even though a large body of academic research exists on the predictors of public attitude toward police, very little is known about how public perceptions of police accountability influence satisfaction with the police. This study seeks to fill that gap by using ordered logistic regression and multi-year community-level survey data from one Western city (n = 3725) to examine the relationship between satisfaction with police accountability and overall attitudes toward the police. The results indicate that respondent satisfaction with police accountability was a strong, consistent predictor of satisfaction with local police, even after controlling for other important variables, such as race/ethnicity and community context. The findings suggest that public perceptions relating to the control of police officer conduct should be considered when assessing the predictors of attitudes toward the police. 相似文献

This paper examines PAC contributions by the Big ThreeU.S. automakers and Japanese auto dealers to Houseincumbents. A regression model is estimated where PACcontributions are a function of a firm's own ties toan incumbent's district (as measured by firmemployment) and those of rivals. For the Big Three,own and U.S. rival effects are positive. Further, theresults do not indicate the presence of a free-ridereffect. Employment by a foreign subsidiary has no neteffect on U.S. contributions. For the Japanesedealers, Japanese plant employment has a positiveimpact on contributions, and that of the Big Three anegative. 相似文献

The situational perspectives theory of job performance is a fundamental aspect of organizational and managerial psychology. Consequently, there is growing interest in conducting additional research to assess situational factors and job performance through the theoretical frameworks of social learning and social exchange theories, which are seldom applied in these domains. The data has been collected from 365 employees working in Pakistan Telecommunication Company Limited (PTCL). It was found that supervisor support stimulates job performance. It is also deduced that self-efficacy mediates the relationship while work engagement does not mediate the relationship between supervisor support and job performance. The situational perspectives theory of job performance provides a supportive framework for the development of PTCL employees. This work should be of interest in the area of situational factors and performance improvement. This study is one of the very few studies conducted to empirically assess the influence of situational factor on performance through the mediating role of work engagement and self-efficacy. 相似文献

We use the principal‐agent model as a focal theoretical frame for synthesizing what we know, both theoretically and empirically, about the design and dynamics of the implementation of performance management systems in the public sector. In this context, we review the growing body of evidence about how performance measurement and incentive systems function in practice and how individuals and organizations respond and adapt to them over time, drawing primarily on examples from performance measurement systems in public education and social welfare programs. We also describe a dynamic framework for performance measurement systems that takes into account strategic behavior of individuals over time, learning about production functions and individual responses, accountability pressures, and the use of information about the relationship of measured performance to value added. Implications are discussed and recommendations derived for improving public sector performance measurement systems. © 2010 by the Association for Public Policy Analysis and Management. 相似文献

Relative risks of violence in psychiatric patients are high compared to the general population and existing evidence in non-psychiatric populations may not translate to reductions in violence in psychiatric populations. We searched 10 databases including Medline, EMBASE, CINAHL and Scopus, from inception until August 2015 for systematic reviews and meta-analyses of violence prevention interventions in psychiatry. Reviews were included if they used a hard outcome measure (i.e. police or hospital recorded violence, or reincarceration) and contained randomized or non-randomized controlled studies. Five reviews met our inclusion criteria (n = 8876 patients in total), of which four received a GRADE rating of ‘low’ or ‘very low’. Three randomized studies (n = 636) reported that therapeutic community interventions may reduce reincarceration in drug-using offenders with co-occurring mental illness (‘moderate’ GRADE rating). The lack of intervention research in violence prevention in general and forensic psychiatry suggests that interventions from non-psychiatric populations may need to be relied upon. 相似文献

The potential for the injury or death of a child resulting from the tip-over of a piece of household furniture or a domestic appliance has not been previously well recognized. We reviewed nine accidental deaths of young children that resulted from avoidable residential hazards and/or lapses in supervision of the children by their caregivers. The offending household items included televisions, bedroom dressers, a kitchen stove, and a lounge chair. The causes of death were mechanical asphyxia, blunt trauma, and combined blunt head trauma and asphyxia. All of the deaths could have been prevented by appropriate anchoring of the piece of furniture and/or closer supervision of the child. A thorough multidisciplinary investigation is essential in establishing the cause and manner of death in such cases and in identifying risk factors that may aid in the prevention of future childhood deaths. 相似文献

Jazz music and jazz musicians have often been linked for better or worse to the world of addictive substances. Many talented jazz musicians either had their careers sidetracked or prematurely ended due to their addiction to drugs and/or alcohol. The rigors of nightly performances, travel, and for many musicians a disapproving society exacted a toll that impacted the creativity of many artists of the genre. The fact that drug and alcohol use had a significant impact on the performance levels of numerous jazz musicians in the 1940's and 1950's has been much discussed, but more study of that impact is warranted. While recent research has provided new information regarding this challenging topic, there is still much to learn. Indeed, a number of questions for inquiry may be posed. Among those questions are the following: Was the work of these jazz artists truly inspired? Would their creative output have been enhanced had they not been addicted to substances? What was the impact of the addictive substances on their ability to function as creative artists and is there evidence to refute or verify that impact? Are there identifiable traits in certain artists that allowed them to be creative in spite of their addictions? This examination presents an evaluation of the evidence of the link between creativity and substance abuse especially as it relates to selected jazz artists during this time period and how they remained creative and actually prospered in their careers in spite of addictions to controlled substances. 相似文献
