This study explores the attitudes of Australian evangelical Christian doctors to healing, suffering and good practice, using in-depth interviews. Doctors described an intellectualised faith, in which medical care was conceived in itself as a way of bearing witness. The alleviation of suffering, for these doctors, included supporting patients to rediscover purpose and meaning in their lives. There was diversity of opinion about evangelising, with many feeling that this was a contingent activity best conducted outside the consultation. This cohort of doctors, mostly non-denominational, had consciously engaged in work with the poor and marginalised as an expression of their faith. 相似文献

Children's, adolescents’, and adults’ (N = 96 7–8, 10–11, and 13–14-year-olds and university students) epistemological development and its relation to judgments and reasoning about teaching methods was examined. The domain (scientific or moral), nature of the topic (controversial or noncontroversial), and teaching method (direct instruction by lectures versus class discussions) were systematically varied. Epistemological development was assessed in the aesthetics, values, and physical truth domains. All participants took the domain, nature of the topic, and teaching method into consideration in ways that showed age-related variations. Epistemological development in the value domain alone was predictive of preferences for class discussions and a critical perspective on teacher-centered direct instruction, even when age was controlled in the analysis. 相似文献

The present study challenges Elkind's widely cited report that a large proportion of American college students—particularly female—cannot conserve volume. Thirty male and 30 female college students were tested individually for conservation of volume on three sets of procedure—the first identical to Elkind's, the second involving displacement of water, and the third identical again to Elkind's. By the end of the third task, 49 Ss were conservers and only two were clearly nonconservers. The others probably had conservation competence. There were no sex differences. 相似文献

The purpose of this research was to test the hypothesis that the relative involvement of peripheral versus central nervous system activity during response variations determines the locus of error production in a subsequent criterion response. The hypothesis was tested by comparing ipsilateral and contralateral transfer of a criterion response following response variations that emphasized proportionately different involvement of the peripheral and central systems. When subjects were provided with knowledge of results (KR) to maintain a 30% maximum voluntary contraction (MVC), ipsilateral but not contralateral bias errors occurred on a subsequent dynamic response. When subjects maintained a 30% MVC without KR, however, subsequent ipsilateral bias errors were greater than contralateral bias errors. Finally, when subjects imaged a 30% MVC, subsequent bias errors were equivalent across limbs. These results are interpreted as support for the hypothesis. 相似文献

Resiliency theory posits that some youth exposed to risk factors do not develop negative behaviors due to the influence of promotive factors. This study examines the effects of cumulative risk and promotive factors on adolescent violent behavior and tests two models of resilience—the compensatory model and the protective model—in a sample of adolescent patients (14–18 years old; n = 726) presenting to an urban emergency department who report violent behavior. Cumulative measures of risk and promotive factors consist of individual characteristics and peer, family, and community influences. Hierarchical multiple regression was used to test the two models of resilience (using cumulative measures of risk and promotive factors) for violent behavior within a sample of youth reporting violent behavior. Higher cumulative risk was associated with higher levels of violent behavior. Higher levels of promotive factors were associated with lower levels of violent behavior and moderated the association between risk and violent behaviors. Our results support the risk-protective model of resiliency and suggest that promotive factors can help reduce the burden of cumulative risk for youth violence. 相似文献

Teenage girls in age-discordant relationships remain of concern for healthy development and well-being. We examine whether factors from several sociological frameworks—self-esteem, deviance, social ecology, family cohesion, and religious involvement—predict entry into such relationships. With longitudinal data on 1,537 adolescent girls, we use structural equation modeling to assess risk and protective factors by age group. Results indicate that few social factors predict entry to such relationships; only religious involvement for the youngest adolescents and self-esteem for middle adolescents predict entry. While adolescent girls who date older males are largely like their peers, any impact of social factors may vary by the developmental stage that adolescent girls occupy. 相似文献

The present paper examines the incidence of deviant messages and images in one of the most widely used modes of interpersonal communication, i.e., birthday cards. The sample consists of 535 birthday cards randomly selected from fourteen retail outlets in a metropolitan (SMSA) area. Each outlet represented a geographically distinct high‐traffic area varying in type of establishment (discount, drug, dime, department, grocery and card stores) and socioeconomic level of the community. Both the incidence and type of deviance, the characteristics of cards in which deviance is represented, and the characteristics of the sender/receiver population are discussed within the context of Goffman's concept of ceremonial activity. 相似文献

Development in reading and math in children from different SES backgrounds: the moderating role of child temperament 下载免费PDF全文

Socioeconomic risks (SES risks) are robust risk factors influencing children's academic development. However, it is unclear whether the effects of SES on academic development operate universally in all children equally or whether they vary differentially in children with particular characteristics. The current study aimed to explore children's temperament as protective or risk factors that potentially moderate the associations between SES risks and academic development. Specifically, latent growth modeling (LGM) was used in two longitudinal datasets with a total of 2236 children to examine how family SES risks and children's temperament interactively predicted the development of reading and math from middle childhood to early adolescence. Results showed that low negative affect, high effortful control, and low surgency mitigated the negative associations between SES risks and both reading and math development in this developmental period. These findings underline the heterogeneous nature of the negative associations between SES risks and academic development and highlight the importance of the interplay between biological and social factors on individual differences in development. 相似文献
