This study examined the associations between sexual self-concept (sexual esteem and sexual anxiety) and sexual self-efficacy (situational and resistive) in a sample of 388 high school students (59% Caucasian, 28% African American). Males reported lower sexual esteem and lower sexual self-efficacy than females. Males and African Americans reported higher levels of sexual anxiety and lower levels of resistive self-efficacy than females and Caucasians. In regression models, higher sexual self-esteem uniquely predicted higher sexual self-efficacy scores, even after controlling for demographic variables, knowledge of sexual risk, and previous coital experience. In post hoc analyses, sexual self-esteem mediated the relation between knowledge of sexual risk and both types of sexual self-efficacy. Results suggest the need for interventions to promote male sexual self-efficacy and sexual esteem and the need for longitudinal research that explicates models of sexual health in adolescence. 相似文献

Cue reactivity, while increasingly recognized as a central feature of drug and alcohol addiction, is not well studied in gambling.
We evaluated the urge to gamble in a simulated casino environment among frequent gamblers who alternated between cycles in
which they observed others playing ten hands of Blackjack (first, third and fifth cycle) and cycles in which they played ten
hands of Blackjack themselves (second and fourth cycle). The played cycles served as a manipulation for the observed cycles
in terms of “priming” (having previously gambled in the environment vs. not) and “anticipation” (expecting more opportunities
to gamble in the environment vs. not) and, thus, allowed these conditions: observed cycle 1 = anticipation (+) and prime (−); observed cycle 2 = anticipation (+) and prime (+); and observed cycle 3 = anticipation (−) and prime (+). Subjects’ urge to gamble was greater in the gambling environment than in a neutral setting
and both positive anticipation and positive priming increased cue reactivity within the gambling environment. The frequency
of gambling outside of the study did not affect cue reactivity. However, a preference for Blackjack (vs. other types of gambling)
and observing winning (vs. losing) hands were both associated with stronger cue reactivity in the study. These findings contribute
to our understanding of pathological gambling. 相似文献

Accumulation of deicing salts in soils in an urban environment 总被引:4,自引:1,他引:3
Mary Ann Cunningham Eric Snyder Daniel Yonkin Morgan Ross Toren Elsen 《Urban Ecosystems》2008,11(1):17-31
Examining rates of deicing salt accumulation and leaching in urban soils is important for understanding the distribution and
movement of salt in the environment. We examined autumn concentrations of deicing salts in soils in a moderately dense urban
landscape in eastern New York State. The study area contrasted to the isolated, rural highways examined in previous studies.
While NaCl was the most abundantly applied salt, Mg2+ (apparently from MgCl2, a secondary deicing salt) was the most abundant salt cation in soils. Moderate Na+ levels, and equivalent concentrations at depth and in surface samples, indicate that leaching of Na+ is rapid in this system. Leaching may ameliorate toxicity for land plants but accelerate inputs to aquatic systems. In contrast
to rural highway studies, where salt levels declined rapidly with distance to pavement, Na+ remained elevated at the maximum distance measured. Airborne salt dispersal and dense networks of pavement likely contribute
to widespread elevated salt levels. This semi-urban setting had salt levels high enough to be toxic to terrestrial plants
and soil protozoa. Even moderate levels of development can have dramatic effects on salt inputs into soils and aquatic systems.

Recently, scholarly work has examined the effect of rising income inequality on health outcomes. However, this work is somewhat inconclusive. The mechanisms that could produce such an association are still being sorted out. Much of this work focuses on mortality outcomes with little attention to how this process operates for actual health conditions, including chronic health problems—arguably the main public health concerns of the developed world. In a series of multilevel binary logistic regression models using data from the 2005 and 2007 Behavioral Risk Factor Surveillance System, we examine the association between state-level income inequality, poverty, and social welfare measures on spending and policy to examine the association between these factors for three chronic health outcomes: diabetes, hypertension, and coronary heart disease. We find that income inequality is conditionally positively related only to the diagnosis of diabetes and hypertension, and only in 2007. However, absolute poverty is related to the outcome across all three dependent variables. Certain social welfare measures attenuate the effects of both income inequality and absolute poverty, suggesting that some policies reduce this association. 相似文献

Family functioning is predictive of youth recidivism in Singapore. However, there is a lack of family based interventions for youth offenders on community probation. Evidence‐based family interventions developed in Western populations, such as Functional Family Therapy (FFT), have been found to be effective in mitigating subsequent youth criminal behavior. However, no study has examined whether such interventions can be implemented and adapted for use in Eastern cultures. Thus, this paper sought to detail the implementation of FFT in Singapore. Rationale for the adoption of FFT is discussed, and key activities undertaken during the first 18 months of implementation are described. Preliminary data suggest that initial implementation efforts were successful. Challenges encountered, and implications in relation to the broader literature are discussed. 相似文献

Continuity,change and complexity in the performance of masculinity among elite young footballers in England 下载免费PDF全文
Following recent research evidencing that young men are redefining the essential components of what it is to be a man, this paper draws on qualitative interviews with 22 elite‐level, English Premier League academy level football (soccer) players to investigate their performances and understandings of masculinity in relation to decreasing homohysteria. Even in this gender‐segregated, near‐total institution, these working‐class, non‐educationally aspiring adolescents evidence an attenuated performance of ‘maleness’ and improved attitudinal disposition toward homosexuality. Congruent with insights developed by inclusive masculinity scholars, respondents maintained emotional closeness and physical tactility with male teammates and friends. These more inclusive attitudes and homosocial behaviours were, however, slightly more conservative than in other recent research. We close by explaining this variation with reference to theoretical apparatus’ provided by Goffman and Bourdieu to advance theoretical debates about social class and masculinities. 相似文献

Over a period of three months, starting in late 2013, Ukraine experienced a remarkable civic transformation. What started as peaceful protests largely consisting of young idealists, grew quickly into an organized yet decentralized social movement, a conglomeration of semi-formal initiatives, and a loosely defined network of related formal and informal organizations—a process that ultimately prompted significant political and social changes in Ukraine. This paper offers three case studies related to EuroMaidan to provide insight into the formal and informal dimensions of civil society, contrasting those with official designations. The discussion contributes to the long-debated question of the strength or weakness of civil society in the context of Eastern Europe and suggests directions for future research with regard to the conceptualization of civil society and our understanding of formality. 相似文献

Adaptation and Validation of the Life Events and Difficulties Schedule for Use With High School Dropouts 下载免费PDF全文

The Life Events and Difficulties Schedule (LEDS) is considered the standard for measuring psychosocial stressor exposure, but it has not been used with academically at‐risk adolescents, including high school dropouts. The goal of this study was to (1) adapt the LEDS for use with this population, and (2) examine the reliability (interrater) and validity (concurrent and predictive) of this adaptation among a sample of vulnerable adolescents (N = 545). Good reliability coefficients (.79–.90) were obtained, and stressor exposure was associated with concurrent criteria indexing mental health outcomes (depression) and major risk factors for dropout (administratively recorded and self‐reported). Also, LEDS scores predicted dropout beyond these risk factors. The adapted LEDS appears useful for describing academically struggling adolescents’ stressor exposure. 相似文献

ABSTRACTCisgender lesbian, gay, bisexual, and queer/questioning (LGBQ) homeless youths are more likely to engage in sexual risk behaviors relative to cisgender heterosexual homeless youths. Homeless youths (N = 1,046) were recruited and surveyed from three drop-in centers in Los Angeles, California. This study assessed differences in demographics, background experiences, and perceived social network norms in order to understand the disparities in rates of unprotected sex and concurrent sex between these two subgroups. Results indicate significant differences in engagement in risk factors as well as social network norms. Findings provide support for tailored sexual risk-reduction interventions that cater specifically to LGBQ homeless youths. 相似文献

Are there racial/ethnic differences in work–family conflict? Using a nationally representative survey of Americans, we analyze differences in work–family conflict among Blacks, Whites, and Hispanics and then utilize an intersectional approach, disaggregating men and women within each racial/ethnic group. Using structural equation modeling, we find that the usual predictors of conflict – family and work characteristics – have varied effects on work–family conflict among men and women of different racial/ethnic groups. Nonstandard schedules were uniformly linked to increased work-to-family conflict among all respondents, regardless of subgroup. Our findings reveal the merits of intersectional approaches, and suggest the need for theoretical models of the work–family interface that better reflect the experiences of men and women of color. 相似文献
