The present research was conducted to clarify the relationships among social anxiety, alcohol consumption, alcohol-related problems, and negative-reinforcement drinking motives among college students. Heavy drinking students (N = 316, 53.80% female) completed self-report measures of social anxiety, alcohol consumption, alcohol-related problems, and drinking motives. Findings indicated that students higher in social anxiety consumed less alcohol but experienced more negative consequences. Moreover, the relationship between social anxiety and negative consequences was mediated by coping and conformity drinking motives in addition to alcohol consumption. In the context of social anxiety, the current research demonstrates the importance of examining problematic drinking as distinct constructs: alcohol consumption and negative consequences. Findings are also discussed in terms of implications for interventions with socially anxious students. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Two goals guided the present study: to develop ecologically relevant and functional interactive-minds settings for the assessment of wisdom-related performance and to investigate whether and under which conditions such settings would facilitate higher levels of wisdom-related performance. After baseline assessment of wisdom-related performance, a sample of 122 natural dyads (244 participants), ranging in age from 20 to 70 years, were randomly assigned to 5 experimental conditions. These conditions varied in the degree to which they were judged to be ecologically relevant and functional and involved the interaction of minds. It was found that performance settings that were judged to be ecologically relevant and functional and provided for actual or "virtual" (internal) interaction of minds increased wisdom-related performance levels by 1 SD. In addition, older adults profited more than younger adults from 1 setting. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The authors explored naltriben's (NTB, a delta opioid antagonist) potential to be a pharmacotherapy for cocaine abuse. NTB (3–6 mg/kg) reduced rats' (Rattus norvegicus) intravenous, self-administration of cocaine, daily, across 5 days. NTB did not, however, interfere with rats' pressing for water. NTB (3 mg/kg) blocked cocaine's facilitation of pressing for brain stimulation, daily, for 5 days. As doses of NTB were explored, it was found that 10 mg/kg of NTB was lethal for about one third of the rats. Smaller doses (e.g., 3 mg/kg) gave some indications of toxicity as indexed by NTB's tendency to reduce pressing for brain stimulation by itself. NTB (3 mg/kg) induced a mild conditioned taste aversion but had no negative effects on rats' ability to learn and remember a sequence of mazes. Taken together, these results lead to the suggestion that opioidergic processes play an important role in mediating cocaine's reinforcement. Although NTB may not be the ideal opioid antagonist for treating people, it has many positive properties supporting further investigation of opioid antagonists as agents for treating cocaine addiction.

Mesoporous materials were obtained from two natural silica sources, diatomite and pumicite, under hydrothermal conditions, autogenic pressure and in presence of the surfactant cetyltrimethylammonium bromide (CTAB) as the template. Using diatomite, a temperature of 383 K and the following molar ratios in the initial reaction gel: SiO2/Al2O3 = 8.86; CTAB/SiO2 = 0.1; Na2O/SiO2 = 0.10–0.25 and H2O/Na2O = 250–300, the mesoporous material MCM‐41 was obtained in a reaction time of 48 h. When pumicite was used, a mesoporous material was obtained in a reaction time of 96 h, a reaction temperature of 423 K and an initial reaction gel with the following molar ratios: SiO2/Al2O3 = 8.86; CTAB/SiO2 = 0.1; Na2O/SiO2 = 0.25 and H2O/Na2O = 330.

The effects of n-3 fatty acid supplementation in the form of fresh fish, fish oil, and docosahexaenoic acid (DHA) oil on the
fatty acid composition of plasma lipid fractions, and platelets and erythrocyte membranes of young healthy male students were
examined. Altogether 59 subjects (aged 19–32 yr, body mass index 16.8–31.3 kg/m2) were randomized into the following diet groups: (i) control group; (ii) fish diet group eating fish meals five times per
week [0.38±0.04 g eicosapentaenoic acid (EPA) and 0.67±0.09 g DHA per day]; (iii) DHA oil group taking algae-derived DHA oil
capsules (1.68 g/d DHA oil group taking algae-derived DHA oil capsules (1.68 g/d DHA in triglyceride form); and (iv) fish
oil group (1.33 g EPA and 0.95 g DHA/d as free fatty acids) for 14 wk. The fatty acid composition of plasma lipids, platelets,
and erythrocyte membranes was analyzed by gas chromatography. The subjects kept 4-d food records four times during the study
to estimate the intake of nutrients. In the fish diet, in DHA oil, and in fish oil groups, the amounts of n-3 fatty acids
increased and those of n-6 fatty acids decreased significantly in plasma lipid fractions and in platelets and erythrocyte
membranes. A positive relationship was shown between the total n-3 polyunsaturated fatty acids (PUFA) and EPA and DHA intake
and the increase in total n-3 PUFA and EPA and DHA in all lipid fractions analyzed. DHA was preferentially incorporated into
phospholipid (PL) and triglyceride (TG) and there was very little uptake in cholesterol ester (CE), while EPA was preferentially
incorporated into PL and CE. The proportion of EPA in plasma lipids and platelets and erythrocyte membranes increased also
by DHA supplementation, and the proportion of linoleic acid increased in platelets and erythrocyte membranes in the DHA oil
group as well. These results suggest retroconversion of DHA to EPA and that DHA also interferes with linoleic acid metabolism. 相似文献

This article is a response to Holloway's critique of developmental models of psychotherapy supervision. Our position is that developmental models of supervision can benefit from taking guidance from and drawing parallels to more general models of human development. It should not be assumed, however, that these models of supervision are direct translations of other models. The metaphor of development has proven useful in a number of domains of human activity. We argue that this analogy is also useful in conceptualizing the training process in counseling and psychotherapy by providing a detailed framework through which changes in trainees over time and optimal supervisory approaches can be examined. Although Holloway's impression of the state of research on developmental models of clinical supervision is that there exists little evidence in support of the models, other authors have noted considerable consistency between the constructs of these models and the published research. We support Holloway's suggestion for improving research methodology in this area, and we note additional directions for future research.
