Environment is a broad concept encompassing the whole range of diverse surrounding in which man perceive, experience and react to events and changes. The present investigation has been designed to study the environmental disposition factors as perceived by German, American and Indian. A group of 392 subjects were selected in this investigation. English, German and Bengali version of Environmental Response Inventory were administered to them. All the three groups have favourable attitude towards pastoralism, which means preservation of natural resources. Besides this, they also express variety of opinion in connection with urbanism, environmental adaptation, need privacy and antiquarianism.  相似文献

大学师范生就业心理健康状况的调查分析   总被引:2,自引:0,他引:2  
运用症状自评量表(SCL-90),采取随机抽样的方法,对师范毕业生进行就业前的心理测试,结果表明大学本科毕业生的心理问题检出率较高,在“SCL-90”因子上的得分均显著高于中国青年常模,这极不利于教师教育的发展和师资水平的提高。  相似文献

Although self-assessment is an important genre in both the academy and the workplace, it is often static. The resulting fixed identities are problematic in a creative economy that requires fluidity. Drawing on the work of Carruthers and Goffman, among others, we argue that memory and meditation, encompassing inventory and invention and coupled with rhetorical performance, constitute dynamic self-assessment.  相似文献

Biodiversity science in China has seen rapid growth over recent decades, ranging from baseline biodiversity studies to understanding the processes behind evolution across dynamic regions such as the Qinghai-Tibetan Plateau. We review research, including species catalogues; biodiversity monitoring; the origins, distributions, maintenance and threats to biodiversity; biodiversity-related ecosystem function and services; and species and ecosystems’ responses to global change. Next, we identify priority topics and offer suggestions and priorities for future biodiversity research in China. These priorities include (i) the ecology and biogeography of the Qinghai-Tibetan Plateau and surrounding mountains, and that of subtropical and tropical forests across China; (ii) marine and inland aquatic biodiversity; and (iii) effective conservation and management to identify and maintain synergies between biodiversity and socio-economic development to fulfil China''s vision for becoming an ecological civilization. In addition, we propose three future strategies: (i) translate advanced biodiversity science into practice for biodiversity conservation; (ii) strengthen capacity building and application of advanced technologies, including high-throughput sequencing, genomics and remote sensing; and (iii) strengthen and expand international collaborations. Based on the recent rapid progress of biodiversity research, China is well positioned to become a global leader in biodiversity research in the near future.  相似文献

拖延:时间管理倾向量表的区分效度   总被引:4,自引:0,他引:4  
拖延可能是时间管理不良的一种后果,也可能是与时间管理相伴随的行为。本研究的目的是回答拖延与时间管理倾向之间的关系,检验时间管理倾向量表的区分效度。研究工具包括时间管理倾向量表、拖延量表;研究对象是233名在校大学生;采用相关分析发现,拖延和时间管理倾向之间存在显著的负相关,表明了时间管理倾向量表的区分效度。  相似文献

The purpose of this study was to validate the IDI (Intercultural Development Inventory) and to assess the impact of international mobility programmes on the intercultural sensitivity of university students. For this, a quasi-experimental study was carried out using a longitudinal design of repeated pre-test and post-test measures, with an experimental group of students who carried out international mobility programmes and a control group of students who did not. The sample consisted of 3,047 university students. The inventory yielded a five-factor structure (negation/defence, minimization, reversion, acceptance/adaptation and encapsulated marginality) with alpha coefficients ranging from .82 to .91, revealing adequate reliability and validity. The results indicate the effectiveness of the IDI to measure intercultural sensitivity. Although the post-test scores are higher than the pre-test scores for both groups, there are significant differences in favour of the experimental group (p = .000) in all factors except the negation/defence stage. The conclusions focus on the implications of this study for curriculum development and policy at an educational level.  相似文献

供应链管理环境下供应商管理用户库存控制方法   总被引:7,自引:0,他引:7  
本在总结传统库存管理方法的基础上,通过引入供应链管理环境下库存管理中的典型问题——长鞭效应,介绍了供应商管理用户库存(vendor managed inventory,VMI)的基本思想,建立了VMI的数学模型,系统地分析了VMI策略对库存总费用以及联合利润的影响.最后,通过一个实例从数据上验证了VMI策略不仅能提高供应商和用户的联合利润,还有利于他们达到充分合作,降低长鞭效应的影响.  相似文献

Many university lecturers are encouraged to implement innovative teaching tools and methodologies such as clickers in order to create an interactive learning environment and improve student learning, but its performance must be evaluated. The aim of this paper is to test empirically the impact of the use of clickers on students' learning processes. The teaching experience applied to the subject of Financial Accounting is specifically described. The total sample size is 77 students from a Business Administration and Economics Degree, taught in English and in Spanish. The analysis, using multivariate techniques, of the questionnaire responses, students' grades and a reflexive experience of the lecturer conclude that learning with clickers is effective. There is a positive relationship between grades and intrinsic motivation through clickers. Consequently, the students' marks are related to its intrinsic motivation, feedback to understanding, students' discussion and its negative aspects but not gender nor age.  相似文献
