农户持续参加科普培训意愿的影响因素

持续参与科普培训对提升农户科学素质具有关键作用。基于社会认知理论,将外部环境划分为参与环境和人际环境两个维度,将农户结果期望划分为素质结果期望和收入结果期望两个维度,采用陕西省305户农户随机分层抽样调研数据,运用Probit模型对农户科普培训持续参与意愿影响因素进行实证分析。研究发现:外部环境和结果期望对农户持续参与意愿均有显著的正向影响,其中素质结果期望在参与环境、人际环境对持续参与意愿的关系中具有中介作用,收入结果期望在参与环境对持续参与意愿的关系中具有中介作用。据此提出营造良好外部环境、增强科普培训的实用性以满足农户结果期望等提升农户持续参与科普培训的建议。     

Asian Women,Job Training and the Social Organization of Immigrant Labor Markets

This paper examines the entry of Asian immigrant women into a gendered labor market via government-funded job training programs. The focus is on the intake processing of clients into an employment training program operated by a community based organization. The study reveals that women's family responsibilities and the cultural capital they bring function to screen them into or out of training programs and ultimately shape their location in the workforce. The study thus draws attention to how race, class, and gender enter into the organization of Asian immigrant women into the labor market. This investigation is based in institutional ethnography (Smith 1987), a research strategy which displays how activities in a particular setting are coordinated with more extended forms of social organization. The study shows that the overriding concern with successful placement in a job as mandated by government regulations is a critical factor in selecting the women for these programs.

边疆民族地区小学教师校本培训评估

借鉴柯氏四级评估法的评价指标,运用问卷调查法和访谈法实地调研了边疆民族地区小学教师及学校管理者,从参训教师及学校管理者的不同视角对校本培训的反应层、学习层、行为层、结果层四个层级来评价培训的实施成效。评估结果显示,边疆民族地区小学教师校本培训的改进方向是确定教师培训需求、优化培训内容以及维持受训教师行为水平。     

出口二元边际、行业异质性与劳动生产率

基于行业异质性视角,文章主要考察出口二元边际对劳动生产率的影响.利用UN Comtrade数据库,采用HK指数法测度中国出口深度边际和出口广度边际,发现中国出口产品种类基本覆盖了世界全部种类的90％.进一步地,借助聚类分析方法综合多种因素区分行业劳动技能异质性,出口二元边际与劳动生产率关系的实证结果显示:总体上出口深度边际显著推动劳动生产率提高,出口广度边际对劳动生产率产生抑制作用.更为重要的是,出口深度边际对劳动生产率的促进作用仅存在于高技能行业,受限于行业产品技术含量和劳动技能水平等,低技能和中等技能行业出口深度边际出现贫困化增长现象.出口种类扩张的生产率损失超过出口溢出效应的生产率收益,出口广度边际对高中低技能行业劳动生产率具有不同程度的负向影响.     

Tolerance of Uncertainty: Links to Happenstance,Career Decision Self‐Efficacy,and Career Satisfaction

This study investigated the extent to which tolerance of uncertainty affects the relationship between happenstance skills and career satisfaction via career decision self‐efficacy. Moderated mediation analysis was conducted on data collected from 321 graduates (175 men, 146 women) of Korean universities making the school‐to‐work transition. Results showed that career decision self‐efficacy fully mediated the relationship between happenstance skills and career satisfaction. Furthermore, the moderation effect of tolerance of uncertainty had a significant impact on the relationship between happenstance skills and career decision self‐efficacy. Tolerance of uncertainty should be considered an important variable in happenstance career theory and intervention. Unplanned influences should also be considered important factors in the career decision‐making process.

Asymptotic relative efficiency of the linear discriminant function under partial nonrandom classification of the training data

This paper considers the problem where the linear discriminant rule is formed from training data that are only partially classified with respect to the two groups of origin. A further complication is that the data of unknown origin do not constitute an observed random sample from a mixture of the two under- lying groups. Under the assumption of a homoscedastic normal model, the overall error rate of the sample linear discriminant rule formed by maximum likelihood from the partially classified training data is derived up to and including terms of the first order in the case of univariate feature data. This first- order expansion of the sample rule so formed is used to define its asymptotic efficiency relative to the rule formed from a completely classified random training set and also to the rule formed from a completely unclassified random set.     

语文课程素养培养模式的探索与建构——以湛江师范学院中文专业为例
