Social Security Reform in China's Transition to a Market Economy 总被引:1,自引:0,他引:1
This paper begins by describing the origins of a social security system that was based on a series of institutional splits that resulted in the development of a fragmented system characterized by inequity and incomplete coverage. The entitlements embedded in this system have proved difficult to revise in the light of changing circumstances and the pressures associated with economic transition, demographic change and the newly emerging problems of open unemployment and urban poverty. These developments, particularly the latter, are creating new demands on a system already struggling to adjust to structural problems of coverage and financial soundness. A series of extensive reforms in the areas of pensions and unemployment insurance and a rationalization of administrative arrangements and responsibilities have been introduced over the last two decades, but further reform seems inevitable as external pressures and policy priorities change. A key goal of the reform process has been to transfer responsibility for social security from enterprises to the state, but the system still suffers from a series of serious financial problems. Despite the extensive reforms that have already been introduced, these problems and the structural imbalances underlying them will require further action. The most important of these imbalances relate to the split between the nature and role of social security in the urban and rural sectors, the role of the commercial provision and its relationship with the state, and the extension of programmes aimed at poverty alleviation. 相似文献

This paper explores the reasons for industries converging upon poor strategies. The phenomenon is likened to the periodic mass suicide of the lemmus lemmus (the Norwegian lemming). It gives historic examples of the phenomenon, and evidence of its occurring within a simulated business environment. A literature review shows how it can be explained using theories from economics, psychology and competitive analogies used in business. An inputs-process–outputs model provides a theoretical framework for Lemmus Lemmus strategies and is used to derive hypotheses. 相似文献

This article is based on a study which examined hypotheses about Japanese marketing using a matched sample of British companies and their major Japanese competitors. Japanese subsidiaries in Britain were shown to be much more marketing-oriented, more responsive to strategic opportunities, and more single-minded in their pursuit of market share. Organizationally, there were few differences between the two groups. The Japanese subsidiaries, however, were more inclined to use product or market-based divisions and continuous, informal planning and control procedures. The result is that managerial focus and responsibility are centred upon overall product-market rather than financial or production performance, with continuous feedback facilitating rapid adaptation and implementation of marketing plans and strategy. 相似文献

The current study examined the interplay between children's dispositional anger and susceptibility to peers' influence in increasing children's risk‐taking behaviors. Participants in the current study were children from a larger study of temperament and social–emotional development who were followed across 9, 24, 36, 48, and 60 months. Dispositional anger was measured using mothers' reports across 9 and 48 months. At 60 months, children played a risk‐taking computer game in presence of an unfamiliar peer who watched the child play. The child's risk‐taking was assessed during the game as the unfamiliar peers' reactions were coded based on comments that were peer directed, reflective of praising the target child's performance, or object directed, indicative of excitement toward the game. A latent profile analysis revealed three longitudinal anger profiles across infancy to early childhood: high stable, average stable, and low stable anger. Results suggested that as peers' object‐directed comments predicted risk‐taking independent of children's anger, the association between peer‐directed comments and risk‐taking was dependent on children's dispositional anger. Specifically, when peers praised the target child's performance, children in the high stable anger profile showed increased risk‐taking propensity. Findings are discussed based on the importance of considering both temperamental characteristics and aspects of the peer context in relation to children's risk‐taking. 相似文献

Leveraging historical data into the design and analysis of phase 2 randomized controlled trials can improve efficiency of drug development programs. Such approaches can reduce sample size without loss of power. Potential issues arise when the current control arm is inconsistent with historical data, which may lead to biased estimates of treatment efficacy, loss of power, or inflated type 1 error. Consideration as to how to borrow historical information is important, and in particular, adjustment for prognostic factors should be considered. This paper will illustrate two motivating case studies of oncology Bayesian augmented control (BAC) trials. In the first example, a glioblastoma study, an informative prior was used for the control arm hazard rate. Sample size savings were 15% to 20% by using a BAC design. In the second example, a pancreatic cancer study, a hierarchical model borrowing method was used, which enabled the extent of borrowing to be determined by consistency of observed study data with historical studies. Supporting Bayesian analyses also adjusted for prognostic factors. Incorporating historical data via Bayesian trial design can provide sample size savings, reduce study duration, and enable a more scientific approach to development of novel therapies by avoiding excess recruitment to a control arm. Various sensitivity analyses are necessary to interpret results. Current industry efforts for data transparency have meaningful implications for access to patient‐level historical data, which, while not critical, is helpful to adjust for potential imbalances in prognostic factors. 相似文献
