This study was designed to examine the influence a potential date’s physical attractiveness and sexual history has on an individual’s intentions to engage in safer sex. Over 1,200 participants completed an Internet survey. The questionnaire presented a randomized biography and photograph and asked participants to rate their interest in dating and having a sexual relationship with the target. Participants were randomly assigned to one of six conditions based on the target’s physical attractiveness (low vs. high) and sexual experience (low, medium, or high). Results indicated that men reported greater intentions to have sex than women did, and all participants reported greater likelihood of having sex when the potential partner was highly attractive. Participants rated men and more experienced targets as more risky sexual partners, and the level of a target’s sexual experience was directly related to participants’ willingness to discuss sexual risks. Results indicate a continuing need to include discussion of cognitive factors in all HIV prevention efforts.  相似文献

The authors examined the relation between self-report psychopathy measures and official records of offending in four samples of justice-involved youth (total N = 447). Psychopathy measures included the Antisocial Process Screening Device (APSD) and a modified version of the Childhood Psychopathy Scale (mCPS). Measures of offending included the total number of preadmission arrest charges for three samples (n = 392) and the total number of offenses in the year following release for two samples (n = 138). Neither measure was a strong correlate of preadmission offenses. Although mCPS scores were associated with postrelease offending in one sample, effects for the APSD were observed only when reoffending was conceptualized as a dichotomous variable, indicating a lack of robustness in this association. The findings suggest caution in the use of self-report measures of psychopathic features for decision making with respect to issues of delinquency risk among justice-involved youth.  相似文献

We studied 9,220 children referred to a comprehensive mental health crisis stabilization program to examine the impact of caregiver capacity on crisis worker decisions to refer children for intensive community-based treatment as opposed to inpatient psychiatric hospitalization. Due to the different role of caregivers in the child welfare system, analyses were stratified by state custody status. Among both groups, there was a significant inverse association between child mental health need and referral to intensive community-based treatment. For children not in state custody with low mental health need, there was no difference in the likelihood of referral to intensive community-based treatment across levels of caregiver capacity. However, for children not in state custody with medium and high mental health needs, those whose caregivers were deficient or severely deficient were significantly more likely to be referred for intensive community-based treatment than were those who had capable caregivers. Multivariate analyses demonstrated similar results after controlling for potential confounding variables and confirmed that caregiver capacity contributes significantly to the logistic model’s classification accuracy. Results suggest further investigation of the impact of caregiver capacity on mental health crisis worker referral decisions is needed.  相似文献

A study of 450 college students demonstrated (a) the importance of a distinction between self-produced and externally produced stressors, (b) the usefulness of a construct of productive load, and (c) stronger relations of the Constructive Thinking Inventory than of the Hardiness Questionnaire with productive load and with mental and physical symptoms. Because a major path through which coping ability influences symptoms is negative emotions, the widely recommended practice of partialing self-reported negative affect out of relations among coping, stress, and symptoms is often inappropriate. However, as total daily stressors (e.g., hassles) consist largely of self-produced stressors, it is highly confounded with coping ability, and it is therefore important to partial coping ability out of relations between total stressors and other variables.  相似文献

This paper presents a monotonic system of Post algebras of order +* whose chain of Post constans is isomorphic with 012 ... -3-2-1. Besides monotonic operations, other unary operations are considered; namely, disjoint operations, the quasi-complement, succesor, and predecessor operations. The successor and predecessor operations are basic for number theory.The editing of this unified version of two previous papers [Epstein, Rasiowa 1990, 1991] by the authors was completed, except for footnotes, while the first author visited at Warsaw University during June–July, 1994. The footnotes were added by the first author in September, 1994.Presented byRyszard Wójcicki  相似文献

In endless facets of physiology, there are points of homeostatic balance, such that too much or too litttle of something can both be deleterious (i.e., an "inverse U" pattern). This is particularly true when considering glucocorticoids (GCs), the adrenals steroid secreted during stress. In the first part of this paper, I review a number of realms in which a paucity and an excess of GCs are both damaging. Some findings are classical (for example, concerning GC effects upon body weight), while some are quite recent and have considerable implications for both physiology and pathophysiology (for example, inverse U's of GC actions in the realm of immunity and neuronal survival). The second part of the review considers the far thornier issue of how such inverse U's of GC actions are generated on a cellular and molecular level. One solution that has evolved, primarily in the hippocampus within the nervous system, involves the presence of two different types of receptors for GCs within the same cells; so long as the two receptors have very different affinities and mediate opposing effects on some cellular endpoint, an inverse U will emerge. The second solution, found in a number of peripheral tissues, involves GCs having opposing effects on the amount of some signal being generated (e.g., an immune cytokine) and the sensitivity of target tissues to that signal; under conditions that appear to be physiologically relevant, inverse U's emerge from this pattern as well. The final section of this review considers the enormous role played by Bruce McEwen in the emergence of this literature. I suggest that while much of this obviously has to do with the facts that have come from his group, another substantial contribution is from his steadying and supportive personality, the veritable embodiment of homeostatic balance.  相似文献
