从整体上看,流动党员的管理无论是在管理思路上还是在管理方式上仍没有走出计划经济时代以单位管理为主、以行政管理为主的被动状态。构建流动党员动态管理机制的主要措施:创新工作思路,党员动态管理应以遵循科学发展观为基本原则;探索有利于党员动态教育管理的有效方法;实施科学管理,健全有利于党员动态教育管理的长效机制。  相似文献

Previous literature has suggested that federal funding can hinder the efficiency of nonprofit organizations, but this has yet not been empirically tested. This study used a two‐stage data envelopment analysis (DEA) model to measure the efficiency of a set of private nonprofit teaching‐oriented colleges, then estimate the impact of federal and state funding on organizational efficiency. The findings indicate that, on average, increases in neither state nor federal funding effect efficiency of nonprofit colleges. Increasing state funding negatively impacted the efficiency of public colleges (N = 799). This study suggests that the challenges for nonprofits that accompany government funding may not rise to a quantifiable negative effect on efficiency.  相似文献

Rapidly expanding mobile network coverage in developing countries offers new ways to reach poor farmers in isolated places. This article explores the potential for Information and Communication Technology to provide agricultural information and extension services to smallholder farmers, and links this to empirical insights of an intervention in Uganda, where community knowledge workers rely on mobile devices to deliver context- and time-sensitive data to farmers. Consistent with theoretical insights related to information inefficiencies, we find that the intervention leads farmers to move away from low-risk low-return crops toward more commercially oriented commodities. Our analysis also suggests that, for the case of maize, the intervention causes farmers to sell less on the market, but at significantly higher prices.  相似文献

回顾农村20年的制度变迁及改革创造的巨大绩效,以家庭联产承包制、乡镇企业和村民自治为主线,可以寻见改革存在路径,即:扩大农民自主权。从经济社会系统的“复杂性”理论角度看,“扩大自主权”这一基层进化的经验经由系统的作用形成了自下而上的组织创新,有助于组织群体的系统转换具有路径依赖性,并以路径效应──政府与农民的互动(自下而上的自发创造与自上而下的自觉选择的互动发展)──拓展积聚了由农民个体自主权扩增而导致的农村社会整体发展效应。现实地看,这一路径必将成为实现农村、农业、农民“三农”现代化的最动态的增效源泉。  相似文献

黄河源区草地生态环境的恶化趋势,并没有因近几年政策的投入而得到遏制.因此,有必要对其形成原因及治理的制度结构进行分析,以厘清此类地区实现可持续发展所必需的制度创新.以黄河源区的玛曲县近三十年过牧历史为案例,对高寒牧区制度变迁中的路径依赖和锁定问题进行了新的阐释,并对可持续性的制度框架进行了设计.  相似文献

Vallerand et al. (2003) have proposed that individuals can have two distinct types of passion toward an activity. Harmonious passion, an internal force leading one to choose to engage in the activity, is proposed to be associated with positive consequences. Obsessive passion, an internal pressure forcing one to engage in an activity, is posited to be associated with negative consequences. The present study sought to determine the role of the two types of passion in various cognitive and affective states associated with dependence and problems with gambling. Participants (n = 412) were recruited at the Montréal Casino and given a questionnaire measuring passion toward gambling, as well as consequences associated with dependence and problem gambling. Results showed that obsessive passion for gambling predicted poorer vitality and concentration in daily tasks, as well as increased rumination, anxiety, negative mood, guilt, and problem gambling. These relations were not found for harmonious passion for gambling. Results are discussed in light of the motivational approach to passion (Vallerand et al., 2003).  相似文献

Summary: We describe depth–based graphical displays that show the interdependence of multivariate distributions. The plots involve one–dimensional curves or bivariate scatterplots, so they are easier to interpret than correlation matrices. The correlation curve, modelled on the scale curve of Liu et al. (1999), compares the volume of the observed central regions with the volume under independence. The correlation DD–plot is the scatterplot of depth values under a reference distribution against depth values under independence. The area of the plot gives a measure of distance from independence. Correlation curve and DD-plot require an independence model as a baseline: Besides classical parametric specifications, a nonparametric estimator, derived from the randomization principle, is used. Combining data depth and the notion of quadrant dependence, quadrant correlation trajectories are obtained which allow simultaneous representation of subsets of variables. The properties of the plots for the multivariate normal distribution are investigated. Some real data examples are illustrated. *This work was completed with the support of Ca Foscari University.  相似文献

全文共分为三个部分 :首先 ,分别通过小于音素和大于音素即音素群的角度 ,论证了音素不是音位归纳的唯一尺度 ;接着 ,在论证了音位归纳能够以音素群作为尺度单位的基础上进一步指出 :元音和辅音、声母和韵母是语音划分的两对不同层次的概念 ,元音和辅音指的是一个个能实实在在发出声音的语音实体 ,具有物理特性和生理特性 ,而韵母和声母则着眼于语音实体间的相互关系 ;最后 ,在回顾两种汉语普通话音位归纳方法的基础上 ,着重论证了所谓“动音素”和“静音素”在提法上存在错误。  相似文献

Although the issue of risk target (e.g., self, others, children) is widely acknowledged in risk perception research, its importance appears underappreciated. To date, most research has been satisfied with demonstrating comparative optimism, i.e., lower perceived risk for the self than others, and exploring its moderators, such as perceived controllability and personal exposure. Much less research has investigated how the issue of target may affect benefit perceptions or key outcomes such as stated preferences for hazard regulation. The current research investigated these issues using data from a public survey of attitudes toward mobile phone technology (N= 1,320). First, results demonstrated comparative optimism for this hazard, and also found moderating effects of both controllability and personal exposure. Second, there was evidence of comparative utility, i.e., users believed that the benefits from mobile phone technology are greater for the self than others. Third, and most important for policy, preferences for handset regulation were best predicted by perceptions of the risks to others but perceived benefits for the self. Results suggest a closer awareness of target can improve prediction of stated preferences for hazard regulation and that it would be profitable for future research to pay more attention to the issue of target for both risk and benefit perceptions.  相似文献

银行风险之间的相关关系会使风险之间相互转化,相互影响,令风险呈现出放大或者缩小的趋势,显著影响着银行风险度量结果的准确性。银行风险集成致力于在充分考虑银行风险相关关系的基础上,对银行风险进行较为准确的度量。但是银行风险具有相关关系种类繁多、表现形式复杂、以及数据的可获得性差等显著特征,导致银行风险的集成度量领域存在诸多挑战。本文对相关性下的银行风险集成研究进行综述,具体从集成对象、集成方法和集成数据三个层次系统展开。首先对银行风险及其蕴含的种类繁多的相关关系类型进行解析,然后分析银行风险相关关系表征出的多种复杂特性,根据对这些特性的刻画能力对银行风险的集成方法进行划分和比较,最后总结了获取银行风险集成数据的多种途径。在此基础上,进一步分析了银行风险集成研究的难点和未来趋势。  相似文献
