天地之子--林语堂综论(下)

林语堂在中国现代文学史和文化史上有着不可替代的地位、价值和意义,他足以可与鲁迅、周作人、胡适、老舍等量齐观,但长期以来他却远未得到应有的重视。林语堂最突出的贡献是作为“天地之子”存在的,这不仅表现在他自山乡走来,形成了“高地的文化观”;也表现在他率性自然、天真童稚的个性与情趣;还表现在他与众不同的人生智慧、思维方式及其文化选择。     

宋人对李白的评价与时代典范的抉择

宋人对李白的认识和理解与唐人有较大差别.受唐人盛赞的李白在宋代文学批评和学术研究中地位不高,颇受冷遇,多受贬抑.对前人的褒贬取舍正体现出一个时代的价值原则,从唐人并尊李杜到宋人独尊杜甫,反映了唐宋不同的社会背景和文化特征.

人力资本投资收益-风险与大学生择业行为

教育投资是人力资本投资的重要形式,大学生完成学业后,面临着要选择职业和实现投资回报。在理论上,家庭财富、教育投入成本、职业收入以及分散劳动收入风险的成本是衡量职业价值的主要指标。从调查实际来看,对职业收入、家庭财富以及可分散劳动收入风险成本的地区、单位等变量的选择是影响大学生择业的重要因素。结论认为,大学生择业过程是在人力资本投资收益-风险约束下,根据个人的风险偏好,以职业价值最大化为目标,把职业收益和职业风险成本统一起来的抉择过程。     

Antecedents and Correlates of Course Cancellation in a University “Drop and Add” Period

Most institutions of higher education allow students to drop or add courses in the first 2–3 weeks of each term (D&A). Arguing that course cancellation is not merely an administrative issue involving enrollment trends but represents complex decision making processes taken by students, this study investigated antecedents and correlates of course cancellation during a D&A period in 109 elective courses. Student ratings of the teachers (SRT) and characteristics of the syllabi distributed in the first class session were investigated as predictors of course cancellation. Rates of cancellation were significantly predicted from SRT and from syllabus workload difficulty—lower quality teachers (SRT-based) and more difficult courses (syllabus-based) being cancelled more frequently. Analysis of a sub-sample of truly elective, high-priority courses revealed that these correlations were intensified in teacher-centered lecture courses, but nullified in student-centered seminar courses, in which students write independent research papers. The importance of students’ course selection and course cancellation as decision making processes, the methodology based on institutional data rather than students’ self-reports, and the unique effects of course difficulty on students’ decisions were discussed.

Assessing Fit in Structural Equation Models: A Monte-Carlo Evaluation of RMSEA Versus SRMR Confidence Intervals and Tests of Close Fit

We compare the accuracy of confidence intervals (CIs) and tests of close fit based on the root mean square error of approximation (RMSEA) with those based on the standardized root mean square residual (SRMR). Investigations used normal and nonnormal data with models ranging from p = 10 to 60 observed variables. CIs and tests of close fit based on the SRMR are generally accurate across all conditions (even at p = 60 with nonnormal data). In contrast, CIs and tests of close fit based on the RMSEA are only accurate in small models. In larger models (p ≥ 30), they incorrectly suggest that models do not fit closely, particularly if sample size is less than 500.     

中外研究生入学与资助政策比较及我国的策略选择

新中国成立以来,我国的研究生教育取得了可喜成就,但与世界发达国家相比尚有待改善。本文仅选择入学制度、学费与资助、学习方式作为比较点,通过对几个发达国家的硕士及以上学位制度的简要描述以及对我国研究生招生“双轨制”存在的原因和弊端的分析,提出通过“学费”的“绳索”把握硕士及以上学位教育的“进口”与“出口”,实现我国研究生招生并轨的制度。
