Help-negation is expressed behaviorally by the refusal or avoidance of available help and cognitively by the inverse relationship
between self-reported symptoms of psychological distress and help-seeking intentions. The current study examined the association
between suicidal ideation and intentions to seek help from friends, family and professional mental health sources in a sample
of 302 Australian university students. Participants were 77.5% female and aged from 18–25 years old, with 85.4% aged 21 years
or younger. Higher levels of suicidal ideation were related to lower help-seeking intentions for family, friends, and professional
mental health care, and higher intentions to seek help from no one. Moderation effects indicated that higher levels of depressive
symptoms strengthen the help-negating effect of suicidal ideation for seeking help from friends, family and no one. The results
indicate that, even at subclinical levels, suicidal ideation impedes the cognitive help-seeking process at the decision making
stage. The results also highlight the importance of improving our understanding of why young people become reluctant to seek
help as their levels of suicidal ideation and depressive symptoms increase. Raising awareness that the experience of suicidal
ideation and depressive symptoms can promote intentions to avoid help might reduce the help-negation effect when symptoms
are first recognized. 相似文献

The review article systematizes the current academic debate on U. S. foreign policy after 9/11. The main focus lies on different explanations of the causes and consequences of the “war on terror”. Such a problem-oriented approach mirrors the heterogeneity of the debate which cannot adequately be captured by the conventional categories of IR research and foreign policy analysis. It is fair to say that the analysis of U. S. foreign policy as a case of empirical investigation profits from this disciplinary emancipation. 相似文献

Balancing alternatives and avoiding false dichotomies to make informed U.S. electricity policy 总被引:1,自引:1,他引:0
Recent events highlight the importance of electric energy policy and how to meet growing electricity demand. Price spikes,
global climate change and other environmental concerns, national security threats, an aging infrastructure, and a restructured
industry with mixed results are challenges that policy makers and the industry must address. Given the capital-intensive nature
of the industry, investment decisions will determine in large part how successfully these challenges are met. One paper that
favors energy efficiency, renewable energy, and small-scale distributed generation is examined in detail to test the proposition
that fossil fuel and nuclear power should be part of the mix of new investments. To determine the future electricity resource
mix requires having a complete and informed picture of the relative costs and benefits of various technologies. The levels
of energy efficiency, renewable resources, and distributed generation can and should be increased, but coal and nuclear generation
investments are also likely to be needed.

Kindergarten teacher ratings of physical aggression, hyperactivity,inattention, anxiety, and prosocial behavior were used to predictself-reported delinquency, peer-rated social withdrawal, and schoolplacement in preadolescence (ages 10 to 12 years) in a large longitudinalsample of boys from low socio-economic neighborhoods. Two analyticstrategies were used: person-oriented and variable-oriented approaches. Inthe person approach, eight clusters, based on the kindergarten behaviors,were used to predict delinquency, social withdrawal, and schoolplacement. In the variable approach, the kindergarten behaviors were used asdimensions in logistic regressions. Family adversity was used as the firstpredictor in both approaches; it significantly predicted all the outcomes inpreadolescence. The results obtained using the two approaches were partly inaccordance. In both sets of results, kindergarten teacher-ratedexternalizing behavior problems were most related to later self-reporteddelinquency, and internalizing problems to peer-rated socialwithdrawal. However, the person approach showed that all patterns ofkindergarten behavior problems increased the risk for placement out of anage-appropriate regular classroom, while only inattention and lack ofprosocial behavior were the significant dimensional predictors of thisnegative outcome according to the variable approach. Also, the personapproach showed that the Multiproblem kindergarten boys had the highestpercentage of comorbidity of preadolescent problems. The ROC curvesindicated that prediction of delinquency, social withdrawal, and schoolplacement were equally accurate using the cluster and variableapproaches. Advantages and limits of both approaches are discussed withreference to their usefulness for clinicians. 相似文献

Playing children discovered several teeth close to the wall surrounding a village church. A subsequent police search yielded further teeth, three neurocranial fragments, a metacarpal bone and the fragment of a long tubular bone. The circumstances along with the results of the investigation and the morphological findings suggested historical bones from a former graveyard. However, a large fragment of bone shaft from a long bone could not definitely be classified as being of human origin. The tibia of a deer was amongst the possibilities considered. Comparative tests run at the Institute of Veterinary Anatomy of the University of Giessen in addition to histological examinations, however, ultimately established the human specificity. Interindividual variability and decomoositional changes were determined as causes for the conspicuous macroscopic and microscopic findings for the tibia fragment. Pathological changes could not be demonstrated. 相似文献

In an age of global combat against terrorism, the recognition and identification of people on document images is of increasing significance. Experiments and calculations have shown that the camera-to-subject distance - not the focal length of the lens - can have a significant effect on facial proportions. Modern passport pictures should be able to function as a reference image for automatic and manual picture comparisons. This requires a defined subject distance. It is completely unclear which subject distance, in the taking of passport photographs, is ideal for the recognition of the actual person. We show here that the camera-to-subject distance that is perceived as ideal is dependent on the face being photographed, even if the distance of 2m was most frequently preferred. So far the problem of the ideal camera-to-subject distance for faces has only been approached through technical calculations. We have, for the first time, answered this question experimentally with a double-blind experiment. Even if there is apparently no ideal camera-to-subject distance valid for every face, 2m can be proposed as ideal for the taking of passport pictures. The first step would actually be the determination of a camera-to-subject distance for the taking of passport pictures within the standards. From an anthropological point of view it would be interesting to find out which facial features allow the preference of a shorter camera-to-subject distance and which allow the preference of a longer camera-to-subject distance. 相似文献

Questionnaire data from 376 undergraduates (mean age=19.3 years) were used to test a model describing interrelationships among deidealization, relatedness, autonomy, and insecurity in late adolescents' relationships with their parents. As expected, deidealization predicted greater autonomy and less relatedness (i.e., more disengagement), greater disengagement predicted greater insecurity, and greater insecurity predicted less autonomy. However, disengagement from parents proved to be a double-edged sword in that it was linked not only to insecurity, but also to feelings of greater separateness and self-directedness in relation, to parents. Additional analyses identified significant associations between the adolescent/parent relationship variables and the adolescents' psychological health and ego identity status.Received her Ph.D. from Yale University.
