Research literature suggests that clinical judgments of men's versus women's behavior and symptoms typically rate the men as more pathological and dangerous. To determine whether this view would extend to assessments of psychologically aggressive actions, two separate versions of a survey listing potentially psychologically abusive behaviors perpetrated by either a wife toward her husband or the identical actions perpetrated by a husband toward his wife were sent to a nationwide sampling of practicing psychologists. Results indicated that psychologists, irrespective of demographics, rated the husband's behavior as more likely to be psychologically abusive and more severe in nature than the wife's use of the same actions. Psychologists did not differentially rely on any of the three contextual factors (i.e., frequency/duration, intent of the perpetrator, and perception of the recipient) to influence their determination that a behavior was "psychological abuse" dependent upon whether the initiator of the psychological actions was the husband or the wife. Future research could assess more directly the rationale for the psychologists' differing views of male versus female behavior. In addition, more normative information is needed to inform mental health professionals as to the prevalence and severity of psychologically aggressive actions in the general population.  相似文献

This brief report summarizes a survey of high school and college representatives and their awareness toward gambling-related problems. The Massachusetts Council on Compulsive Gambling developed a survey instrument to review the policies and training programs of 20 high schools and 10 colleges that were located within the catchment areas of Massachusetts Department of Public Health state-sponsored gambling treatment programs. The results revealed that there is an important discrepancy between the prevalence of gambling-related problems among young people and the awareness of these problems among educators. High school and colleges evidence a paucity of existing gambling-related regulations or policies. There is little opportunity for students and educators to learn within the school setting about gambling and its potential hazards. Without sufficient in-service education and training for faculty and staff, there is little likelihood that this group of educators can engage in the early identification or prevention efforts that are so vital to advancing the health and welfare of young people.  相似文献

To examine whether welfare serves as an incentive to early childbearing, this article explores the first steps in the process of becoming a teenage parent: risk of first voluntary sexual intercourse at an early age and, among teens having sex, contraceptive use at first intercourse. Alternative operationalizations of welfare include the AFDC benefit level in the state of residence, the ratio of the benefit level to family income, community-level welfare receipt, and family history of welfare receipt. Results do not support the hypothesis that higher welfare benefits provide an incentive that hastens sex or reduces contraceptive use. Analyses provide moderate support for a culture of poverty perspective among girls. Intergenerational welfare receipt has a borderline significant effect on the timing of first sex, and maternal welfare receipt predicts nonuse of contraception at first sex for girls. Strong support is found for a stressful life experiences perspective, in which both parental marital disruption and nonvoluntary sex predict earlier voluntary sex.

Automobile accident risks vary significantly across populations, places, and times. This study describes the time-varying pattern of societal risk. The relative risks of occupant fatality per person-mile of travel are estimated here for each hour of the week, using 1983 data. The results exhibit a strong time-of-day effect and have a highly skewed frequency distribution, implying wide variations in risk-taking behavior. Indeed, the 168 hourly estimates ranged from a low of 0.32 times the average around Sunday noon to a high of 43 times the average at 3:00 a.m. on Sunday, i.e., by a factor of 134 from bottom to top. Quantile-quantile plots or "Lorenz curves," introduced to display the unequal distribution of risks, show that approximately 34% of the vehicle occupant fatalities occur in hours representing only 5% of the travel. These findings have serious implications for risk analysis. First, when attempting to reconcile objective and subjective risk estimates, risk communicators should carefully control for when and to whom the risk in question is applicable. Second, comparisons of hazards on the basis of average risk are necessarily misleading for risks distributed so unevenly. Third, resource allocation decisions can benefit by knowing how incidence, exposure, and risk vary across time, place, and other relevant variables. Finally, certain cost-benefit analyses that use average values to estimate risk exposure can be misleading.  相似文献

Learning classification trees   总被引:11,自引:0,他引:11  
Algorithms for learning classification trees have had successes in artificial intelligence and statistics over many years. This paper outlines how a tree learning algorithm can be derived using Bayesian statistics. This introduces Bayesian techniques for splitting, smoothing, and tree averaging. The splitting rule is similar to Quinlan's information gain, while smoothing and averaging replace pruning. Comparative experiments with reimplementations of a minimum encoding approach,c4 (Quinlanet al., 1987) andcart (Breimanet al., 1984), show that the full Bayesian algorithm can produce more accurate predictions than versions of these other approaches, though pays a computational price.  相似文献

This article uses data from interviews with 462 individuals enrolled in methadone treatment programs in New York City to compare the gambling and gambling-related drug use and criminal activities of those males (N=72) and females (N=27) found to be pathological gamblers. Both the male and female pathological gamblers were and continue to be actively involved in various forms of gambling. A greater proportion of males had engaged in almost all specific types of gambling, although differences between males and females were not all statistically significant. Males and females were very similar in terms of their patterns of drug and alcohol use and the substances they used when gambling. Males and females shared some reasons but also had separate reasons as to why they used heroin when they gambled. Males especially may participate in a variety of criminal and hustling activities to have the money to be able to gamble or to pay gambling debts. The implications of this research are discussed.This study was supported by grant 1RO3-DA08348, Prevalence of Gambling Problems Among Methadone Patients, from the National Institute on Drug Abuse, awarded to National Development and Research Institutes, Inc.

Following up on Zirin’s (2008) challenge that sports sociologists “get off the bench,” and Karen and Washington’s (2001) plea to make sports sociology more central to analyses of social power, this article empirically reviews and assesses the sociology of sports from 1977–2008. Using a sample of 441 articles selected from the three major sports sociology journals during that period, we conclude that sports sociology exhibits a strong and increasing bias toward micro‐level analyses of (for example) how the content of sports frames and constructs the social world. A smaller and shrinking body of work examines more macro‐oriented issues such as the economics and politics of sports, and there seem to be few attempts to meaningfully synthesize these micro and macro orientations. We think this partiality toward micro‐oriented frameworks is rooted in factors unique to sports sociology while also reflecting larger trends within sociology as a whole. As advocates of popularly accessible public sociology, we respectfully suggest that sports sociologists try harder to weave macro analyses into their work, not necessarily replacing micro‐level approaches, but complementing them. We believe that sports sociology is well‐positioned to become a standard bearer for public sociology, but only if it pays more attention to the way organized sports intertwines with the organizational, political, and economic forces that perpetuate and exacerbate social inequality.  相似文献

Society has a negative attitude toward people with intellectual disabilities or psychiatric disabilities. It is well documented that they are subjected to prejudice, stigma, and negative attitudes (Di Giulio, 2003 ; Finger, 1994 ). Professional literature indicates that information about disabilities and encounters with persons with disabilities can change negative attitudes (Carter, Hughes, Copeland, & Breen, 2001 ; Krajewski & Flaherty, 2000 ). This study accompanied 164 9th-grade students from various junior high schools throughout Israel. Half of the students participated in an integration program for changing attitudes toward persons with disabilities, and the other half served as the control group. The research examined the existence and the degree of relationship between participation in the program, changes in attitudes toward people with disabilities, and self-image. The research findings pointed to a positive change in attitudes of the participants of the program in comparison with the control group, resulting mainly from personal contact with people with disabilities. No relationship was found between levels of self-image of the research group and attitudes toward people with disabilities.  相似文献

Prior research has demonstrated the link between maternal depression during pregnancy (i.e., prenatal depression) and increased neurodevelopmental dysregulation in offspring. However, little is known about the roles of key hypothalamic–pituitary axis regulatory genes in the placenta modulating this association. This study will examine whether placental gene expression levels of 11β‐hydroxysteroid dehydrogenase type 2 (HSD11B2), glucocorticoid receptor (NR3C1), and mineralocorticoid receptor (NR3C2) can help elucidate the underlying mechanisms linking prenatal depression to infant temperament, particularly in infants with high negativity and low emotion regulation. Stored placenta tissues (N = 153) were used to quantify messenger ribonucleic acid levels of HSD11B2, NR3C1, and NR3C2. Assessments of prenatal depression and infant temperament at 6 months of age were ascertained via maternal report. Results found that prenatal depression was associated with increased Negative Affectivity (p < .05) after controlling for postnatal depression and psychosocial characteristics. Furthermore, the association between prenatal depression and Negative Affectivity was moderated by gene expression levels of HSD11B2, NR3C1, and NR3C2 such that greater gene expression significantly lessened the association between prenatal depression and Negative Affectivity. Our findings suggest that individual differences in placental gene expression may be used as an early marker of susceptibility or resilience to prenatal adversity.  相似文献

This paper reviews current research that has primarily focused on domestic violence among same-gender couples. Several key issues pertaining to the identification, assessment, and treatment of domestic violence among same-gender couples are examined and outlined to assist clinicians in effectively working with gay and lesbian clients who may be experiencing domestic violence. Resource information is included to help mental health clinicians recognize specific stressors of marginalized individuals as well as assessment and treatment recommendations are made.  相似文献
