非均衡能力结构下西部地区发展战略探讨——东西部比较的视角

撇开各种外生变量的影响,一个区域经济发展的水平取决于区域内生性能力要素和外在性能力要素的水平及其组合状态。目前中国西部地区内生性能力要素与外在性能力要素组合严重失衡,资源优势及"后发优势"无从发挥。西部开发中传统的思路和做法已经走到尽头。通过区内整合和区际协同,改造区域体制属性、健全市场机制,改革政府管理,培植企业能力,提高民众素质,实现内生性能力与外在性能力高平衡态发展,是西部地区发展战略的着力点。

Cognitive Risk Factors to the Development of Anxiety and Depressive Disorders in Adolescents

This exploratory study examines cognitive risk factors, anxiety sensitivity, and positive and negative affect, as related to the development of anxiety and depression. In a mailed survey, adolescents completed the Child Anxiety Sensitivity Index and the Positive and Negative Affectivity Scale. Previous research utilized the broad and unified variable of anxiety sensitivity as a predictor of anxiety. In this study, we separate and examine the four specific factors of anxiety sensitivity: mental incapacitation concerns, social concerns, disease concerns, and unsteady concerns, and relate it to specific anxiety disorders and depression. Results indicate good convergent validity and improved divergent validity when utilizing the four factors of anxiety sensitivity as compared to using it as one construct. Results also suggest: (1) OCD and GAD share numerous similarities and (2) the importance of the role of negative affectivity in anxiety and depression. Being aware of the components of anxiety sensitivity and how they relate to specific anxiety disorders can help a social worker when rendering a diagnosis. Part of the data presented in this article was from David A. Dia’s doctoral dissertation.

政企信息资源有效整合机制及其制约因素分析

随着电子信息技术的发展,建立政企信息资源整合机制是有效和可行的。有效的政企信息资源整合机制有三个层次:公用信息层、信息资料层、信息决策层。针对这三个层次建立政企信息资源整合机制模型,可对其制约因素,如交互平台、信息标准、行政管理部门的协调及其他相关的制约因素进行系统分析,形成政府为主导,科学规划、建立信息资源机制,提高信息资源共享性的对策。     

The changing importance of white women's economic prospects for assortative mating

Given recent changes in the labor force participation and economic standing of women, we ask whether a woman's position in the labor market has become a more important determinant of her position in the marriage market. Unlike much prior research on trends over time in assortative mating, we take an individual‐level approach to the analysis and rely on improved measures of labor market position, such as measuring wives' wages before marriage and considering multiple indicators of husbands' longer term economic standing. Our analysis relies on data from the National Longitudinal Survey of Young Women (N = 759) and the National Longitudinal Survey of Youth (N = 767). Our results are consistent with growth over time in the importance of women's earnings potential in determining their marriage prospects.     

农业科技成果转化的制约因素及转化模式

农户在农业科技成果推广的过程中,既可以是成果的接受者,也可以是成果的扩散者,农业科技成果向农户转化会受到一些因素的制约。认识和把握农业科技成果向农户转化的制约因素及其转化模式,可以为农业科技成果向农户的顺利转化奠定理论基础。     

铁路既有线电气化改造工程安全预警模型研究

铁路既有线电气化改造施工工程与新线建设工程相比具有的特点是：连续的工程施工流程被分割、分散;工程施工不能对已建立的设施和设备造成伤害;受到客流及货流等人为影响因素多。施工环境的特殊性决定了既有线电气化改造工程施工的高风险性。根据安全管理理论及人－机－环系统工程理论,既有线电气化改造工程施工中的不安全因素有人员因素、设备材料因素、环境因素、安全管理因素等。分析安全影响因素可以建立安全预警模型,在一定程度上预防安全事故的发生,实现安全生产。
