阎连科出生在贫困的乡村,由于童年和少年时期的缺失性体验而产生一种向往城市的心理。这种心理在他的小说中体现为贫瘠土地上的青年农民拼命逃离土地、渴望进入城市的迫切心情。他的小说可以让人感受到主人公在逃离土地之路上挣扎的痛苦心声,同时也可体味到作者希冀精神上回归土地的殷切心情。 相似文献

Conceptualizing anxiety among social work students: implications for social work education 总被引:1,自引:0,他引:1
Stephanie L. Baird 《Social Work Education》2016,35(6):719-732
Student anxiety is frequently discussed within social work education. Due to its potentially devastating impacts, social work educators need to have a full understanding of anxiety in this context, in order to determine the best way to support students. Research on student anxiety from a broad body of literature provides implications for social work classrooms and field education. Key underlying concepts from previous social work and related research on student anxiety inform a conceptual model to help educators develop a more complex understanding of student anxiety. Implications for further research and important next steps in the development of support strategies for social work students are identified. 相似文献

荣昌陶器技艺是中国传统陶器技艺的重要组织部分,因其历史悠久、工艺精湛而久负盛名,与江苏宜兴陶、云南建水陶、广西钦州陶并称为中国四大名陶,荣昌又与广东佛山、江苏宜兴一起被誉为中国“三大陶都”。在千百年的传承和发展过程中,荣昌陶器为巴蜀地区人民的生产和生活曾做出过重要贡献。在非物质文化遗产保护热兴起的今天,重新梳理荣昌陶器技艺产生和发展的场境,发掘潜藏在陶器技艺背后的经济和文化动因,能够使我们在文化生态和生产条件发生巨大变化的今天更好地保护、传承和发展荣昌陶艺。 相似文献

According to recent findings, nonprofit organizations should address the relationships of nonprofit service quality, satisfaction, loyalty, and organizational identification when planning and evaluating donor surveys. This article presents a donor satisfaction barometer that can be used to gain insights into the strength of these key relationships and thereby establish a basis for calculated relevant indices. With such indices, nonprofit organizations can compare stakeholder performance over time and benchmark themselves against other organizations. Data from 2,599 blood donors to one section of the German Red Cross, collected through the proposed donor satisfaction barometer, show that service quality drives satisfaction, and donor satisfaction and organizational identification both exert significant positive effects on donor loyalty. Therefore, nonprofit organizations should use a combined strategic approach that improves both donor satisfaction and organizational identification to increase donor loyalty. The successful application of the donor satisfaction barometer also suggests its value for other nonprofit industries and offers important insights for managers. 相似文献

In this paper, we develop modified versions of the likelihood ratio test for multivariate heteroskedastic errors-in-variables regression models. The error terms are allowed to follow a multivariate distribution in the elliptical class of distributions, which has the normal distribution as a special case. We derive the Skovgaard-adjusted likelihood ratio statistics, which follow a chi-squared distribution with a high degree of accuracy. We conduct a simulation study and show that the proposed tests display superior finite sample behaviour as compared to the standard likelihood ratio test. We illustrate the usefulness of our results in applied settings using a data set from the WHO MONICA Project on cardiovascular disease. 相似文献

The professional decision-making in research (PDR) measure was administered to 400 National Institutes of Health (NIH)-funded and industry-funded investigators, along with measures of cynicism, moral disengagement, compliance disengagement, impulsivity, work stressors, knowledge of responsible conduct of research (RCR), and socially desirable response tendencies. Negative associations were found for the PDR and measures of cynicism, moral disengagement, and compliance disengagement, while positive associations were found for the PDR and RCR knowledge and positive urgency, an impulsivity subscale. PDR scores were not related to socially desirable responding, or to measures of work stressors and the remaining impulsivity subscales. In a multivariate logistic regression analysis, lower moral disengagement scores, higher RCR knowledge, and identifying the United States as one’s nation of origin emerged as key predictors of stronger performance on the PDR. The implications of these findings for understanding the measurement of decision-making in research and future directions for research and RCR education are discussed. 相似文献

近年来,我国的美学研究蓬勃发展,美学基本原理探讨成效显著,中外美学史梳理有条不紊,部门美学研究异彩纷呈,流派美学研究乐此不疲。其主要特征有五:一是参与者众,成果五花八门;二是师承关系明显,排异性强;三是教材各异,令人无所适从;四是思辨者多,实验取证者少,归纳总结者多,创新者少;五是学位论文俨然成为新见主产地。研究方法主要有哲学思辨法、心理还原法以及语义分析、经验主义、社会学、历史学、系统论等。不足之处即为缺乏理论创新,鲜有大师级人物出现,故此未来之研究应以创新为第一要务,力求把深奥难懂的美学理论阐发得通俗易懂。 相似文献
