A quantitative exploration into environmental determinants of two types of higher education spending

Regression analyses were conducted on environmental determinants of two types of higher education spending. As hypothesized, those states which were able to expend large amounts of money per full-time student were not the same states who spend generously in relation to the college-age population.     

运算放大器极点频率的一种估测方法

用滞后的一阶阻容网络与运放构成负反馈闭环连接时，若电路中使用的运算放大器在零分贝增益以上频段存在第二极点频率，则电路可能产生自激振荡，自激振荡的频率与运放的第二极点频率及反馈网络参数三者之间有内在关系，基于这种关系，可以根据电路的振频和反馈环节电路参数估求运算放大器的第二极点频率。     

Educational expenditures and student engagement: When does money matter?

The few studies focusing on the relationships between higher education expenditures and student outcomes have produced contradictory results. This study hypothesized that the lack of consistent relationships is a function of the fact that the effects of expenditures on outcomes are mediated by student engagement. Furthermore, it is expected that the relationships between expenditures and outcomes are contingent on the characteristics of the students and institutions being studied. The present research examined the relationships between higher education expenditures and students’ engagement in educationally purposeful activities, after controlling for a variety of student and institutional characteristics. Using data from a nationally representative sample of colleges and universities, the findings indicated that the relationships between expenditures and student engagement are very complex. Relationships differed by institutional control, students’ year in school, and the type of engagement measure included in the analysis.     

基于现金持有量视角的企业经营效率提升研究

良性的现金持有量是企业赖以生存的基础,但是目前我国许多企业存在超额持有现金或现金持有不足的问题,严重制约了企业的健康发展。基于现金持有量的视角,发现现金持有水平与反映企业经营效率的关键指标息息相关。因此,企业需要关注现金持有量对经营效率的影响,通过改善现金持有量模式,不断提高经营效率,保证长期高效发展。在现金持有量视角下,提升企业经营效率的具体措施包括:构建现金持有量的动态调整机制,完善现金内部控制,提高资金营运能力,拓展多种融资渠道。

组建学科教育师资智能结构之管见

本文概括了组建中小学学科教育师资智能结构的三组关系：整体结构的学科专业储备与教育科学修养、教育科学的理论水平提高与操作能力培训、学科专业的知识结论掌握与学科结构研究，针对以前者为重的现实问题，阐明了应予后者以重视的主张，兼及改革学科教育学课程、科学地组建学科教育师资智能结构的某些对策。     

合同农业运行模式探析——对我省合同农业运行模式的思考

合同农业是新形势下中国农业发展的新事物。我省合同农业运行模式的发展问题,已成为入世后过渡期我省农业深化发展的一个重大问题。目前,我省农业产业化经营模式类型呈现多样性,即经历了从“公司+农户”、“粮库+农户”模式,到“公司+基地+农户”、“公司+协会+基地+农户”模式,再到“公司+科技实体+基地”模式的发展。但无论采用哪种模式都必须把握好四个重要环节:一要签好合同,二是政府要摆正位置,三要诚实信用,四要以法律作保证。     

Institutional Expenditures and Student Engagement: a Role for Financial Resources in Enhancing Student Learning and Development?

The concept of student engagement is receiving increased attention from researchers, higher education leaders, and the general public in recent years. This increased attention represents a shift from the more traditional resource and reputation model of academic quality to a model that emphasizes institutional best practices and student experiences that enhance student learning and development. At the same time, institutions face rising operating costs and the public faces rising costs of attendance. However, relatively little effort has been made to explore the potential relationship between these two important research and policy areas. This study examined the relationship between institutional expenditures and student engagement based on data from 142 colleges and universities. The results of an OLS multiple regression model, including a factor for student engagement as the dependent variable, suggest that administrative expenditures are negatively related to student engagement. These results support further exploration of potential complex causal links between expenditures and engagement and may provide support for initiatives to reverse historical trends and adjust institutional spending.I would like to thank Ms. Cathy Statham for assistance in obtaining data for this study.

我国当前中小学课程运作机制的转变研究——一个亟待关注的研究课题

课程运作机制是指课程运作的内在方式、原理。它是近年来课程理论研究的一个新的生长点,它的深入研究将有助于推进课程变革的进程。课程运作机制的研究应遵循一种整体性研究取向。对课程运作机制进行研究,可以克服课程研究理想化和功利化的倾向,有效解决集权与分权的关系,从而实现课程决策与课程研究的结合。
