That males have higher suicide rates than females is one of the most empirically documented social facts in suicidology, but the reasons for this continue to be debated. For the present paper, we tested a neglected contributing factor to the gender suicide ratio: wound site or the area of the body that is wounded in firearm suicides. Males may have a higher suicide rate, in part, due to their greater likelihood than women for shooting themselves in the head as opposed to the body. This has been related to gender differences in fear of facial disfigurement and suicide intent. Data from the Wayne County Medical examiner's office regarding 807 suicides committed with firearms was analyzed. The dependent variable was dichotomous and referred to the location of the site of the wound: gunshot to the head vs. gunshot to the body. Controls for demographic covariates of suicide included age and race of the suicide victim. The results of the multivariate logistic regression analysis determined that women were 47% less apt than men to shoot themselves in the head. Further analysis determined that women were less apt than men to use shotguns and rifles in their suicides (weapons that make head shooting more awkward). The findings are consistent with the notion that women are more concerned than men with facial disfigurement, and that women have a lower desire to die than men. 相似文献

An integrated theoretical model using constructs from multiple behavioral models was applied to understand and predict condom use among a sample of injecting drug users, commercial sex workers, men who have sex with men, and multipartnered heterosexuals. Elicitation interviews were conducted to develop a questionnaire to measure model constructs that may be predictive of condom use for sex with vaginal, anal, and oral regular and casual partners. A prospective survey design was used, with 993 participants interviewed at Time 1, and 686 returning for Time 2 interviews 3 months later. Regression analyses were conducted using Time 1 measures to predict intention and Time 2 behavior. Strong support was found for a model that includes attitude, social norm, and facilitators/constraints as predictors of behavior, with multiple correlations in the 0.20 to 0.40 range. Findings also indicate perceived control and facilitators/constraints are distinct constructs and both, along with attitude and social norm, contribute to explaining behavioral intention. Implications for intervention development are discussed. 相似文献

Two baboons (Papio papio) successfully learned relational matching-to-sample: They picked the choice display that involved the same relation among 16 pictures (same or different) as the sample display, although the sample display shared no pictures with the choice displays. The baboons generalized relational matching behavior to sample displays created from novel pictures. Further experiments varying the number of sample pictures and the mixture of same and different sample pictures suggested that entropy plays a key role in the baboons' conceptual behavior. Two humans (Homo sapiens) were similarly trained and tested; their behavior was both similar to and different from the baboons' behavior. The results suggest that animals other than humans and chimpanzees can discriminate the relation between relations. They further suggest that entropy detection may underlie same-different conceptualization, but that additional processes may participate in human conceptualization. 相似文献

Maternal report of types of conduct problems in a high-risk sample of 228 boys and 80 girls (ages 4–18) were examined, using a version of the Child Behavior Checklist, expanded to include a range of covert and overt antisocial items (stealing, lying, physical aggression, relational aggression, substance use, and impulsivity). Age and sex effects were investigated. Boys were significantly more physically aggressive than girls. There were no sex differences for stealing, lying, relational aggression, and substance use. Lying and substance use increased with age, whereas relational aggression and impulsivity peaked during early adolescence. A small group of girls had pervasive conduct problems across multiple domains. For some domains such as stealing, lying, and relational aggression, girls showed at least as many problems as boys. Girls, in general, tended to have fewer conduct problems. On the other hand, when assessed across multiple domains, conduct problems in high-risk girls were possibly more pervasive than in high-risk boys, suggesting the possibility of a gender paradox. 相似文献

The temporal relations among candidate causes were studied in a causal induction task using a design that is known to produce occasion setting in animal learning preparations. For some subset of the observations, one event, the occasion setter, was accompanied by another event, the conditional cause; for another subset of the observations, the conditional cause occurred alone. The efficacy of the conditional cause depended on whether it was or was not accompanied by the occasion setter. Participants used the occasion setter to modulate their effect expectancy to the conditional cause when the events were presented serially, but not simultaneously. Current causal induction models are unable to account for the full range of effects that we observed; the relative roles of time, attention, and cue distinctiveness are discussed. 相似文献

In 2 experiments involving computer-rendered versions of single shapes or "geons," the extent to which depth rotation affects the visual discrimination performance of pigeons in both go/no-go and forced-choice tasks was documented. The pigeons were able to recognize geons at most rotations in depth; however, the pigeons' recognition performance was better at the training view than at most other views. Aspects of these results are both consistent with and problematic for object-centered and viewer-centered theories of object recognition. 相似文献

As part of the WHO/EURO Multicentre Study on Parasuicide, the level of suicide intent among female and male parasuicide patients from various European regions was compared. From nine regions, a total of 1,212 parasuicide patients, 752 females and 460 males, were included in the study. Although some statistical significant differences in level of suicide intent between the regions and genders were found, the effect sizes of these relationships were so small that the differences have neither theoretical nor practical significance. As far as level of suicide intent is concerned, the WHO study has succeeded in recruiting a relatively homogeneous group of self-harming patients across borders of region, culture, and country. 相似文献
