The purpose of this study was to verify the validity of a French version of the Positive and Negative Perfectionism Scale developed by L. A. Terry-Short (1995). This instrument measures the type as well as the level of perfectionism in adolescents. The instrument was first administered to 734 7th, 9th, and 11th grade students. Four weeks later, 596 Ss were invited to answer the questionnaire once more. The factorial structure, temporal stability and internal consistency of each subscales of the translated version of the instrument correspond to those of the original version.

Because errors in recall are an important contributor to assessments of children's credibility as witnesses, the author explored children's errors when recounting details of trauma injuries that resulted in hospital Emergency Room treatment. 37 preschool aged children (aged 2–5 yrs) and 11 9-yr-olds (comparison Ss) were recruited in the emergency room and interviewed at home both within a few days of the injury and after 6 mo. Adult witnesses were also interviewed to corroborate children's accounts. Although 2-yr-old Ss made more errors than did older children, the information provided was accurate, even 6 mo after their injuries. The errors were not random; rather, information that was likely to be important in real-world cases was retained quite accurately, while some other categories of information (e.g., the 1st person to respond to their injury) were more error-prone.

This study examined drinking to cope with distress and drinking behavior in a baseline sample of 412 unipolar depressed patients assessed 4 times over a 10-year period. Baseline drinking to cope operated prospectively as a risk factor for more alcohol consumption at 1-, 4, and 10-year follow-ups and for more drinking problems at 1- and 4-year follow-ups. Findings elucidate a key mechanism in this process by showing that drinking to cope strengthened the link between depressive symptoms and drinking behavior. Individuals who had a stronger propensity to drink to cope at baseline showed a stronger connection between depressive symptoms and both alcohol consumption and drinking problems.

Assessed the impact of school-based social competence training on skills, social adjustment, and self-reported substance use of 282 6th and 7th graders. Training emphasized broad-based competence promotion in conjunction with domain-specific application to substance abuse prevention. The 20-session program comprised 6 units: stress management, self-esteem, problem solving, substances and health information, assertiveness, and social networks. Findings indicated positive training effects on Ss' skills in handling interpersonal problems and coping with anxiety. Teacher ratings revealed improvements in Ss' constructive conflict resolution with peers, impulse control, and popularity. Self-report ratings indicated gains in problem-solving efficacy. Results suggest some preventive impact on self-reported substance use intentions and excessive alcohol use. In general, the program was found to be beneficial for both inner-city and suburban students. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The importance of cellular internalization of antibody-targeted carbon nanotubes in the photothermal ablation of breast cancer cells 总被引:1,自引:0,他引:1
Single-walled carbon nanotubes (CNTs) convert absorbed near infrared (NIR) light into heat. The use of CNTs in the NIR-mediated photothermal ablation of tumor cells is attractive because the penetration of NIR light through normal tissues is optimal and the side effects are minimal. Targeted thermal ablation with minimal collateral damage can be achieved by using CNTs attached to tumor-specific monoclonal antibodies (MAbs). However, the role that the cellular internalization of CNTs plays in the subsequent sensitivity of the target cells to NIR-mediated photothermal ablation remains undefined. To address this issue, we used CNTs covalently coupled to an anti-Her2 or a control MAb and tested their ability to bind, internalize, and photothermally ablate Her2(+) but not Her2(-) breast cancer cell lines. Using flow cytometry, immunofluorescence, and confocal Raman microscopy, we observed the gradual time-dependent receptor-mediated endocytosis of anti-Her2-CNTs whereas a control MAb-CNT conjugate did not bind to the cells. Most importantly, the Her2(+) cells that internalized the MAb-CNTs were more sensitive to NIR-mediated photothermal damage than cells that could bind to, but not internalize the MAb-CNTs. These results suggest that both the targeting and internalization of MAb-CNTs might result in the most effective thermal ablation of tumor cells following their exposure to NIR light. 相似文献

Argues that, in adult relationships, insecure attachments reflect strategies for managing a greater level of narcissistic vulnerability than exists in secure attachment. Attachment theory (AT) has traditionally emphasized adaptive responses in the child–parent relationship. However, researchers have applied AT to adult love relationships. Both the child literature and the adult literature have explored individual differences in attachment behavior and have identified stylistic categories of secure and insecure attachments. Although the insecure categories are characterized by overt behavior that appears quite different (i.e., clinging vs distance), in adult relationships where attachment is reciprocal, these stylistic patterns may achieve a similar function.

As part of an effort to characterize the uncertainties associated with heat flux measurements in a fire environment, an uncertainty analysis example was performed using measurement data from a room corner surface products test that followed the guidelines of ISO 9705. Equations to model the heat transfer at the surface of a Schmidt‐Boelter (thermopile) type total heat flux gauge were selected for use to calculate the incident radiative flux from a total heat flux measurement. The effects of the heat flux measurement uncertainty sources were evaluated by conducting an uncertainty propagation on the resulting equation for incident radiation. For the model equations and the example conditions selected, the free‐stream temperature estimate and the heat flux gauge calibration constant were determined to be major uncertainty contributors. The study demonstrates how to systematically identify major sources of uncertainty for the purpose of reducing total uncertainty and thereby enhancing experiment design.

Stressful events in the lives of 309 10- to 15-year-olds and stressful events and psychological symptoms reported by their parents were examined in a 9-month study. Ss' self-reported emotional/behavioral problems were predicted by their reports of stressful events and their fathers' reports of psychological symptoms in cross-sectional analyses. Analyses at follow-up after controlling for initial reports of emotional/behavioral problems and prospective analyses predicting from first assessment to follow-up yielded significant effects for Ss' self-reported stressful events. Mothers' reports of children's problems were predicted by mothers' psychological symptoms in cross-sectional analyses and at follow-up after controlling for initial emotional/behavioral problems. Only prior levels of maternal reports of emotional/behavioral problems predicted mothers' reports of their children's problems 9 months later.

In a conceptual replication and extension of a study by S. L. Bem and E. Lenney (1976), 90 male and 118 female college students rated their comfort in and preference for performing several series of masculine, feminine, and neutral activities. Correlations between ratings and scores on the masculinity (instrumentality) and femininity (expressiveness) scales of the Personal Attributes Questionnaire (PAQ) of J. T. Spence and R. L. Helmreich (1978) tended to be theoretically reasonable in sign but in each sex were low in magnitude and only occasionally significant. Classification of Ss into 4 PAQ groups (androgynous, masculine, feminine, and undifferentiated) on their joint masculinity and femininity scores revealed that androgynous and masculine Ss of both sexes had higher comfort ratings, independent of type of task, than did feminine and undifferentiated Ss, suggesting the importance of instrumentality and expressiveness per se. For forced-choice preference ratings, significant differences were found only in males, masculine Ss having a stronger preference for sex-typed tasks than those in other categorical groups. The PAQ variable, however, accounted for only a small percentage of the variance. The data support the Spence-Helmreich hypotheses that the PAQ and similar instruments are largely measures of instrumental and expressive personality traits rather than sex roles and that these personality dimensions are only minimally related to many sex role behaviors.
