The compressive deformation and fracture features of Zr59Cu20Al10Ni8Ti3 bulk metallic glassy samples with aspect ratios in the range of 0.67–2.00 have been investigated. The compressive plastic strain of the glass monotonically increases with decreasing aspect ratio, but the maximum strength almost maintains a constant value of 1.77–1.88?GPa. All the compressive shear-band angles are equal to?~40° if modified by the rotation of the primary shear bands.  相似文献

The purpose is to identify the motivations and barriers to physical activity (PA) among the three largest ethnic groups in Hawaii (Hawaiians/part-Hawaiians, Japanese, and Filipinos). University of Hawai'i students (N = 32, aged 18+) self-identified as one of those ethnicities participated in focus groups. There are more common themes than ethnic-specific variations in factors influencing PA. PA is understood as exercise among all groups; leisure time PA like running and surfing are common activities. Results were more similar among Hawaiian and Japanese than with Filipino participants. The findings offer an opportunity for improving cross-cultural and culture-specific PA interventions for those ethnicities.  相似文献

The present study is a cross-sectional survey that investigates ethical practices among Chinese psychotherapists from the perspective of a large representative sample of Chinese clients (N?=?1,100). In reports from clients, we found that psychotherapists did poorly in providing informed consent and had other ethical difficulties in the therapeutic setting and with dual relationships. We conclude that Chinese culture, especially Confucianism, had significant impact on the attitudes toward the psychotherapists' ethical practices, which complicated ethical dilemmas. It is important for cross-cultural psychotherapists to become sensitive to the influences of traditional Chinese culture when counseling Chinese clients.  相似文献

A modified proactive interference paradigm was developed to investigate encoding and memory processes in preschool-age children. The buildup and release from proactive interference in preschool-age children parallels that of adults and of mentally retarded persons, indicating that very young children and older people may use many of the same encoding dimensions.  相似文献

International behavioral research requires instruments that are not culturally-biased to assess sensation seeking. In this study we described a culturally adapted version of the Brief Sensation Seeking Scale for Chinese (BSSS-C) and its psychometric characteristics. The adapted scale was assessed using an adult sample (n = 238) with diverse educational and residential backgrounds. The BSSS-C (Cronbach alpha = 0.90) was correlated with the original Brief Sensation Seeking Scale (r = 0.85, p < 0.01) and fitted the four-factor model well (CFI = 0.98, SRMR = 0.03). The scale scores significantly predicted intention to and actual engagement in a number of health risk behaviors, including alcohol consumption, cigarette smoking, and sexual risk behaviors. In conclusion, the BSSS-C has adequate reliability and validity, supporting its utility in China and potential in other developing countries.  相似文献

Abstract

Research is just a set of conventions‐‐the most rigorous way to ask a question and look for answers...research is people-run. And it can be as flexible as the people who run it (Hatch & Farhady, 1982, p. xv).  相似文献

Conventional cognitive-behavioral therapy for social anxiety disorder, which is closely based on the treatment for depression, has been shown to be effective in numerous randomized placebo-controlled trials. Although this intervention is more effective than waitlist control group and placebo conditions, a considerable number of clients do not respond to this approach. Newer approaches include techniques specifically tailored to this particular population. One of these techniques, social mishap exposure practice, is associated with significant improvement in treatment gains. We will describe here the theoretical framework for social mishap exposures that addresses the client's exaggerated estimation of social cost. We will then present clinical observations and outcome data of a client who underwent treatment that included such social mishap exposures. Findings are discussed in the context of treatment implications and directions for future research.  相似文献

记忆监测是有赖于状态的.还是有赖于特质的?实验针对两种预见性监测任务——任务难度的预见(EOL)和学习程度的判断(JOL),选用三种实验材料,对记忆监测的准确性进行了跨任务、跨情境的一致性考察。发现在任务难度的预见与学习程度的判断的准确性之间,存在着跨任务的高度一致性;在不同的三项材料之间.存在着跨情境的高度相关。本研究结果从一个侧面支持了记忆监测的特质说。  相似文献

选取44063名青少年为调查对象,采用《青少年心理健康素质调查表·动力系统分量表》考察我国青少年动力系统的发展特点。结果表明:(1)从整体上看,我国青少年的动力系统发展状况良好;(2)我国青少年的动力系统年级变化趋势表现出小学五年级得分较高,初一年级略有上升,初二年级有所下降,之后起伏波动,高三年级得分最低,但从高三年级到大学阶段迅速上升,大学阶段得分最高;(3)我国青少年在动力系统各维度上均存在显著年级差异,但在各维度上呈现出不同的年级变化趋势。  相似文献
