论预约的效力

预约合同的产生是商品经济日益发达的产物,随着市场经济的不断发展,现实生活中预约纠纷层出不穷,但由于对该问题我国法律还没有作出专门的规定,以致许多纠纷都不能得到及时有效地解决。理论上,对预约问题也关注不够,少有的研究也是诸多争议,尤其是预约效力问题。因而,对当前预约效力的两种主要观点——"必须磋商说"和"必须缔约说"进行分析实为必要,并在此基础上阐明"必须缔约说"的合理性,提出当事人的具体义务及义务违反后的法律责任,以期对现实纠纷的解决有所裨益。

The Mediating Effect of Happiness on the Job Satisfaction of Aging Filipino Workers: A Structural Equation Model (SEM)

Job satisfaction is a frequently studied topic among scholars, but only few have taken into account the job satisfaction of older workers. This study aims to develop a model that describes the mediating effect of happiness on job satisfaction specifically on a select group of aging Filipino workers. This paper utilized structural equation modeling (SEM) for its data analysis to test what impact happiness has on job satisfaction. Three hundred aging Filipino workers, both from public and private organizations in the Philippines, took part in this study by completing a five-part research tool that consists of a Robotfoto (a Dutch term that describes a photo-like picture drawn by police to describe a suspect from a witness's illustration) and adopted questionnaires for physical and mental well-being, employee recognition, happiness, and job satisfaction. The structural equation model revealed that physical and mental well-being and employee recognition significantly affect—and are predictors of—happiness. Moreover, it was found that happiness has an impact on the job satisfaction of older workers. Findings generated in this study cater relevant ideas in developing programs and practices for the aging workforce in the field of Human Resource Management.     

Exploring gender gap and school differential effects in mathematics in Chilean primary schools

ABSTRACT

Despite the systematic recognition of large gender gaps in favour of boys in mathematics performance in Chile, the role of schools in explaining this gap has been comparatively underresearched. This paper analyses a longitudinal dataset to explore within- and between-school variation of Chilean primary schools in promoting attainment and progress of girls and boys. In order to reflect the hierarchical nature of the educational data, multilevel modelling is used, with 163,044 students, nested within 3,355 schools, within 310 municipalities to fit raw, contextualised attainment, and value-added models. The weak evidence indicative of gender differential school effect in progress in Chilean primary schools was interpreted as non-substantive. However, differences in effectiveness played a significant role, as girls progressed more than boys in less effective schools, but the opposite was true in more effective schools. Finally, the study concludes that the Chilean gender gap needs to be addressed mainly beyond schools.     

承压含水层中反应性溶质运移实验与模拟研究——以苯胺和1,2-萘醌-4-磺酸钠为例

反应性溶质运移机理和模拟是地下水污染防治的前提和基础.为了考察化学反应和水流条件对溶质运移的影响,本文设计了承压含水层物理模型,以苯胺和1,2-萘醌-4-磺酸钠化学反应为例,开展了双分子化学反应条件下不同流速溶质运移实验和模拟研究,得到主要结论如下：（1）利用变系数二级反应率改进的ADRE模型能够较好地模拟在3种不同流速下双分子反应性溶质运移行为,峰值浓度相对误差分别为4.5％、5.0％及10.1％,模型可行,且模拟精度较高.（2）随着流速增大,模型参数m减小,而β0则增大.（3）模型对参数m值变化最敏感,其次是β0值,较不敏感的是弥散系数D.（4）随着流速增大,反应物和产物穿透曲线的不规则性加强,存在较明显的“拖尾”现象,今后需要进行机理方面的研究.     

团体沙盘治疗对网络依赖大学生干预效果的研究

科技创新基地与平台建设支持政策关联性研究

2006年初,《国家中长期科学和技术发展规划纲要(2006-2020)》(以下简称《规划纲要》)中提到加强科技基础条件平台建设,后续出台一系列支撑政策。本文运用政策分析方法和统计数据,系统分析《规划纲要》配套政策及其实施细则中科技创新基地与平台建设部分的政策关联性。研究表明,我国已经初步建成科技创新基地与平台政策体系,现有的大部分实施细则较好地支撑配套政策,但还存在部分实施细则与配套政策不一致,平台建设存在资源重复配置等问题。为增强我国创新基础能力,我国应尽快规范完善科技创新基地与平台建设相关边界与类型,归并部分职能相似的平台,具体细化实施细则,加强统筹平台投资建设和运营管理机制,充分发挥平台集聚高端创新资源能力。
