在国际金融危机环境下,中小企业贷款困难尤其突出,有很多企业因为资金链的断裂而被迫破产。同时,从银行方面针对中小企业信用评级方面来看,在方法、效率和成本方面又是按照国有大型企业同样的方法和标准来做,这些方法和标准对于中小企业并不很合适。在考察了我国中小企业目前面临较为困难的融资情况之后,开发出了一套智能化的、信息化的,专门针对中小企业的信用评价系统,Smart Credit Evaluation System for SMEs(SCEC)。 相似文献

With the recent release of the National Core Arts Standards (NCAS), educators need new consistent, fair assessments of drama learning. As an initial starting point, this paper reports on the creation of the LATA Drama Performance Rubric, a standards-based assessment to measure learning occurring under real drama classroom conditions that we hope evaluators will find to be useful. A widespread group of drama instructors coordinated with researchers to create a rubric containing four categories: (1) Diction and Volume; (2) Movement and Gesture; (3) Group Coordination; and (4) Stage Presence. Field testing of the instrument with 97 students in the treatment group and 80 students in the control group demonstrated its ability to distinguish between fourth-grade classrooms that had and had not received long-term drama instruction. Reliability, validity, and NCAS alignment are discussed, along with limitations and future recommendations. 相似文献

随着新课程改革的不断深入,教学理念逐步更新,学生的英语水平也在逐渐提高,但沿用多年的高考英语书面表达的评分标准并没有与时俱进,已经不能完全适应英语教学改革的要求。笔者认为,与《课程标准》相对照,它存在对学生的书面表达能力要求偏低的问题;与托福等考试的写作评分标准相比较,其整体评分方式不确定度相对较大,分项式描述不尽合理。针对上述问题,本文提出了"改良的整体评分法"的建议。 相似文献

Accumulating evidence suggests children enrolled in full-time child care often display afternoon elevations of the hormone cortisol, which is an indicator of stress. Recent advances in immunoassays allow for measurement of activity in the hypothalamic–pituitary–adrenal axis and the autonomic sympathetic nervous system from saliva, and measurement of both systems provides a more complete understanding of activity in the stress response system. This study is the first to examine both cortisol and alpha-amylase in children attending child care and focuses on the influences of specific indicators of classroom process quality. A diverse sample of 63 preschool children nested in 14 classrooms of varying quality participated in this study; child salivary cortisol and alpha-amylase were collected at six times over 2 days. Results indicate that children in classrooms with higher Emotional Support displayed a greater decline in cortisol from morning to afternoon. Further, children in classrooms with higher Emotional Support exhibited lower total alpha-amylase output while attending child care. Implications for professional development for early childhood teachers and measurement of classroom quality are discussed. 相似文献
