Surrogate endpoints frequently substitute for rare outcomes in research. The ability to learn about completed suicides by investigating more readily available and proximate outcomes, such as suicide attempts, has obvious appeal. However, concerns with surrogates from the statistical science perspective exist, and mounting evidence from psychometric, neurochemical, genetic, and neuroimaging studies suggests that surrogates may be particularly problematic in suicide research. The need for greater phenotypic refinement of suicide-related behaviors, development of and adherence to a shared suicide nomenclature, and conservative interpretation of investigational results that are limited to the precise population and suicide-related behavior under examination are discussed. 相似文献

This paper exemplifies a secondary data analysis of context-specific differences in children's hyperactivity-impulsivity while controlling for informant-specific effects. Participants were boys and girls from the NICHD Study of Early Child Care and Youth Development who were measured in 1(st), 3(rd), and 5(th) grades. Latent factor models were structured using multi-informant reports including mothers, fathers, teachers, and observers. Temporal stability within a context was stronger than cross-context consistency, and the magnitude of longitudinal stability was higher in the home context compared to the school context. Controlling for informant-specific effects resulted in a significantly improved model fit and increased within-context stability. Our findings highlight the importance of considering both context and informant effects when studying longitudinal stability and change in personality development. 相似文献

This study examined several propositions of social cognitive career theory (
[Lent et al., 1994] and [Lent et al., 2000]) with a sample of 393 Mexican American college students. It was hypothesized that person input (i.e., age) and background contextual variables (i.e., Anglo orientation, Mexican orientation, familism, instrumentality, and expressivity) would predict career self-efficacy across Holland’s (1997) six RIASEC types. In addition, we examined the proposed relations between career self-efficacy, career interests, and career choice goal across the six RIASEC areas. Our results indicated that (a) Artistic, Social, Enterprising, and Conventional career models were similar across gender and university affiliation groups, (b) gender differences were found in the Realistic career model, (c) institutional affiliation differences were found in the Investigative career model, and (d) the models were a good fit to the data. Implications for future vocational research and career interventions are discussed. 相似文献

The current study presents a method for assessing the relative effects of attention and escape on noncompliance in preschoolers. Attention and escape conditions were alternated in a multielement design, and a contingency reversal procedure, in which one test condition served as a control for the other, was used to demonstrate control. For all 3 participants, noncompliance was maintained, at least in part, by social attention. Functional analyses of noncompliance such as the one described here may be valuable for developing function‐based treatments. 相似文献

This case series aims to examine the preliminary efficacy, acceptability and feasibility of Family-Based Treatment to promote
weight restoration in young adults with anorexia nervosa. Four young adults with sub/threshold anorexia nervosa were provided
11–20 sessions of Family-Based Treatment for young adults with pre-, post- and follow-up assessments. At post- and follow-up,
3/4 participants were in the normal weight range, 3/4 were in the non-clinical range on the Eating Disorders Examination and
reported being not/mildly depressed. At post-treatment, 2/4 were in the good psychosocial functioning range and by follow-up,
3/4 were in this range. These results suggest that Family-Based Treatment for young adults with anorexia nervosa is a promising
treatment. 相似文献

In this article, a framework is suggested to deal with the analysis of global environmental risk governance. Climate Change
is taken as a particular form of contemporary environmental risk, and mobilised to refine and characterize some salient aspects
of new governance challenges. A governance framework is elaborated along three basic features: (1) a close relationship with
science, (2) an in-built reflexivity, and (3) forms of governmentality. The UNFCCC-centered system is then assessed according
to this three-tier framework. While the two-first requisites are largely met, the analysis of governmentality points to some
institutional weak spots. 相似文献

In representational momentum (RM), the final position of a moving target is mislocalized in the direction of motion. Here, the effect of a concurrent sound on visual RM was demonstrated. A visual stimulus moved horizontally and disappeared at unpredictable positions. A complex tone without any motion cues was presented continuously from the beginning of the visual motion. As compared with a silent condition, the RM magnitude increased when the sound lasted longer than and decreased when it did not last as long as the visual motion. However, the RM was unchanged when a brief complex tone was presented before or after the target disappeared (Experiment 2) or when the onset of the long-lasting sound was not synchronized with that of the visual motion (Experiments 3 and 4). These findings suggest that visual motion representation can be modulated by a sound if the visual motion information is firmly associated with the auditory information. 相似文献

The present study has investigated the occurrence of body image dissatisfaction among adolescent schoolgirls in Amman, Jordan, and the risk factors that are known to predispose it including individual, familial and social variables. A sample of 326 adolescent girls aged 10–16 years was recruited from public and private schools in Amman. Participants completed a socio-demographic data sheet, eating attitude test, and body shape questionnaire. Approximately, 21.2% of participants displayed body image dissatisfaction in which physical changes associated with puberty and exhibiting negative eating attitudes were associated with this dissatisfaction. Additionally, mass media messages, as well as peers and family pressures towards thinness were associated with participants’ preoccupation with their body image. In conclusion, negative body image perception was observed in the present sample. Therefore, well-controlled prospective studies and development of intervention programs on body image among adolescent girls in Jordan are needed. 相似文献

A great deal has been made of the question of whether nano-materials provide a unique set of ethical challenges. Equally important
is the question of whether they provide a unique set of regulatory challenges. In the last 18 months, the US Environmental
Protection Agency has begun the process of trying to meet the regulatory challenge of nano using the Toxic Substances Control
Act (1976)(TSCA). In this central piece of legislation, ‘newness’ is a critical concept. Current EPA policy, we argue, does
not adequately (or ethically) deal with the novelty of nano. This paper is an exploration of how to do a better job of accounting
for nanomaterials as ‘new.’ We explore three alternative ways that nanomaterials might be made to fall under the TSCA regulatory
umbrella. Since nanomaterials are of interest precisely because of the exciting new properties that emerge at the nano-scale,
each of these three alternatives must meet what we call the ‘novelty condition’ and avoid what we call the ‘central paradox’
of existing regulatory policy. Failure to meet either of these conditions is a moral failure. We examine both the strengths
and weaknesses of each alternative in order to illuminate the conceptual, practical, and moral challenges of novelty. 相似文献
