This study introduces a social context model within which peer acceptances of prosocial-leadership, aggression, and social withdrawal were examined as functions of the contextual norms of these behaviors. The major postulate of the model is that the extent to which a behavior permeates a social context facilitates peer acceptance of the behavior. Specific hypotheses with respect to classroom and gender as different social contexts were formulated and supported when tested in a sample of 4,650 Chinese middle school students from 82 classes. The discussion emphasizes the theoretical as well as the methodological need for alternative conceptualizations of peer relations that reflect both individual differences and contextual variations.

Data for three rivers in the upper Severn catchment are examined to assess the influence of regulation strategies on the thermal characteristics. Seasonal and diel temperature variations are markedly influence by the release discharge and the depth of withdrawal from the reservoir. The downstream influence of river regulation is confined to a relatively short reach (ca. 30 km) below the dams. Nevertheless, the control of water temperature during hot, dry summers could benefit salmon populations.  相似文献

This study examined the interactive effects of individual cultural orientation with work-family conflict on employees' job withdrawal intentions. Using a sample of 394 employees from the banking sector in the United States and China, the authors found that work interfering with family (WIF) was more positively related to job withdrawal intentions among individuals scoring high on idiocentrism. It is interesting to note that the authors (unexpectedly) found that family interfering with work (FIW) was more positively related to job withdrawal intentions for those scoring high on allocentrism or low on idiocentrism. Implications and directions for future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

大港油田地下储气库可行性研究   总被引:4,自引:0,他引:4  
通过对大港油田已枯竭的板820气藏的更加深入的地质研究,重新评价了该气藏的储集层和盖层,论证了作为地下储气库的地质可行性;通过对开发史分析研究,论证了作为地下储气库的开发可行性,并计算了气藏开发动态储量。根据多年来对天津市供气规律,确定了储气库调峰周期和基本参数。设计了注采井生产能力和注采方案。根据经济评价,认为利用废弃气藏作为地下储气库经济效益显著。图2表1(郭海莉摘)  相似文献

This research examined how syndromal approaches to assessment can obscure differences between children in the quality of their social interactions. Mixed boys (high for externalizing and internalizing problems) showed heterogeneity in the responses they evoked from others: For one subgroup, aggression and withdrawal evoked aversive responses from others, and even prosocial behavior evoked hostile peer responses; for the other, aggression and withdrawal evoked positive peer responses. Externalizing boys also showed heterogeneity in the patterning of their evoked responses. Within-group heterogeneity was not explained by boys' syndrome scores but was linked to their reactions to specific antecedent events. The results illustrate how a contextualized analysis of behavior can reveal distinctive social interactional patterns that underlie similar overall rates of problem behaviors.

H储气库运行初期出现了数次弱震或微震,研究该区注采诱发地层应力场变化及断层易滑动性对小震级地震的影响具有重要的意义。为此,通过钻孔崩落数据和震源机制解反演了工区应力方向,并且基于钻孔崩落及钻孔诱发张裂缝数据,利用应力多边形理论来约束应力量值范围;然后,根据多孔介质弹性理论来估算气田开采和储气库周期注采情况下地层应力的变化,进而讨论断层滑动趋势与小震级地震的关系;在此基础上,得出了H储气库最大允许孔隙压力值。研究结果表明:① H储气库工区最大水平主应力方向为N21°E~N23°E,与区域现代构造应力场结果较一致;②H储气库注采前储层段水平最大、最小和垂直主应力量值分别为151.3±11.6 MPa,72.7±3.0 MPa和80.2±1.2 MPa,应力结构类型为走滑型;③在H气田开采初期储层段应力结构类型为逆冲型,而随着天然气的采出逐步转换为走滑型,之后储气库的周期注采使得应力结构类型在走滑型与逆冲型之间转换;④随着天然气开采,断层滑动趋势数值降低,而储气库注气有可能会增加断层滑动的风险,H断层滑动趋势数值随着储气库周期注采而发生周期性变化;⑤诱发微震发生的临界断层滑动趋势数值为0.45±0.03,避免微震发生的最大允许地层压力为27.7 MPa。  相似文献

Readers and secondary services are alerted that, through no fault of her own, two nearly identical articles by Denise C. Park have been published. A full report of the research appeared in the American Psychological Association publication, Psychology and Aging. The full reference follows: Park, D. C., Morrell, R. W., Frieske, D., & Kincaid, D. (1992). Medication adherence behaviors in older adults: Effects of external cognitive supports. Psychology and Aging, 7,252-256 (see record 1992-36400-001). Although Dr. Park expressly denied in writing to the conference editors permission to publish the full text of the paper in the conference proceedings, the full text nonetheless was published as follows: Park, D. C., Morrell, R. W., Frieske, D., & Kincaid, D. (1992). Copyright 1992 by the American Psychological Association. Medication adherence behaviors in young and old adults: Effects of cognitive interventions. In H. Bouma & J. A. M. Graafmans (Eds.), Studies in health technology and infomatics: Volume 3. Gerontechnology (pp. 401-406). Amsterdam: IOS Press. Citations to this research should be made, as the author intended, to the primary archival publication in Psychology and Aging.

It was hypothesized that chronic schizophrenics exposed to sustained group problem solving experience would tend to improve their levels of social participation on criterion tasks socially more challenging and complex. It was further hypothesized that such improvement would generalize to task performance with total strangers and to social behavior on the ward. All predictions except the one about ward behavior were confirmed by experimental findings with 32 chronic schizophrenic patients. It is suggested that sustained social experience in situations which elicit social participation permit factors to, become operative which reduce anxiety associated with socially more challenging, complex situations and thus facilitate participation in such situations.
