When Teachers' and Parents' Values Differ: Teachers' Ratings of Academic Competence in Children From Low-Income Families.

The authors examined predictors of teachers' ratings of academic competence of 105 kindergarten children from low-income families. Teachers rated target children's expected competence in literacy and math and completed questions about their perceptions of congruence-dissonance between themselves and the child's parents regarding education-related values. Independent examiners assessed children's literacy and math skills. Teachers' instructional styles were observed and rated along dimensions of curriculum-centered and student-centered practices. Controlling for children's skills and socioeconomic status, teachers rated children as less competent when they perceived value differences with parents. These patterns were stronger for teachers who exhibited curriculum-centered, rather than student-centered, practices. The findings suggest a mechanism by which some children from low-income families enter a path of diminished expectations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

关于征地制度的思考

针对当前农村土地问题的现状．认为调整农村土地关系改革土地制度是解决当前农村问题的关键之一。介绍苏格兰土地改革的经验．提出农村土地转为非农用地的交易中国家应实行限制性措施．可尝试建立“国家失地农民账户”和“国家失地农民保障基金”．从而合理分配土地交易产生的级差收益保障失地农民的合法利益。     

Trajectories leading to school-age conduct problems.

The present study applied a semiparametric mixture model to a sample of 284 low-income boys to model developmental trajectories of overt conduct problems from ages 2 to 8. As in research on older children, 4 developmental trajectories were identified: a persistent problem trajectory, a high-level desister trajectory, a moderate-level desister trajectory, and a persistent low trajectory. Follow-up analyses indicated that initially high and low groups were differentiated in early childhood by high child fearlessness and elevated maternal depressive symptomatology. Persistent problem and high desister trajectories were differentiated by high child fearlessness and maternal rejecting parenting. The implications of the results for early intervention research are discussed, with an emphasis on the identification of at-risk parent-child dyads.

技术杠杆系数的研究——技术进步对企业息税前收益的影响

提出了技术杠杆的概念,并就技术成本杠杆和技术价格杠杆对企业息税前收益变化的影响程度进行了探讨,经理论计算说明了通过技术进步不但可以提高企业的息税前收益,而且当企业的经济效益越差时,技术进步使产品的变动成本降低或使产品的单位售价提高而带来的企业息税前收益提高的速度越快。     

TD-LTE与TD-SCDMA切换判决机制的探究与仿真

不同网络之间的切换问题是网络间互操作的重要组成部分,尤其是当前备受关注的TD-LTE与TD-SCDMA的切换问题。该文在对常规切换机制剖析的基础上,通过详尽的理论分析,根据现有切换机制的不足,提出了新的切换判决算法机制。新机制中结合了多属性切换判决中的层次分析算法和二维函数收益法,考虑了移动用户的业务喜好,并使用Matlab搭建了网络模型着重针对数据业务进行仿真,根据不同的网络收益值来实现切换的选择,验证了数据业务切换判决算法的有效性。     

银行监管有效性体系的建构

为提升我国银行监管的有效性,在借鉴国际社会银行监管经验的基础上,采用比较分析的方法,构建适合我国国情的银行监管有效性指标体系．利用该指标体系对我国银行监管现状进行分析,结果表明,我国银行监管收益指标中的稳定性指标比较理想,但存款人保护等指标仍有较大提升空间．银行监管成本高,即银行监管应在提高各项收益指标的前提下,尽可能削减监管成本．
