冯雪峰是“修正主义文艺”批判运动第一阶段( 1956~ 1962)主要的批判对象.作 为唯一的参加过长征的左翼文艺理论家,冯雪峰于1957年遭遇清算,除了他那不合时宜的革命 现实主义理论的启蒙倾向,还有一个重要的原因,就是19世纪30年代已然形成、长期以来没 能解决的宗派主义从中作祟.  相似文献

Networks of ambient monitoring stations are used to monitor environmental pollution fields such as those for acid rain and air pollution. Such stations provide regular measurements of pollutant concentrations. The networks are established for a variety of purposes at various times so often several stations measuring different subsets of pollutant concentrations can be found in compact geographical regions. The problem of statistically combining these disparate information sources into a single 'network' then arises. Capitalizing on the efficiencies so achieved can then lead to the secondary problem of extending this network. The subject of this paper is a set of 31 air pollution monitoring stations in southern Ontario. Each of these regularly measures a particular subset of ionic sulphate, sulphite, nitrite and ozone. However, this subset varies from station to station. For example only two stations measure all four. Some measure just one. We describe a Bayesian framework for integrating the measurements of these stations to yield a spatial predictive distribution for unmonitored sites and unmeasured concentrations at existing stations. Furthermore we show how this network can be extended by using an entropy maximization criterion. The methods assume that the multivariate response field being measured has a joint Gaussian distribution conditional on its mean and covariance function. A conjugate prior is used for these parameters, some of its hyperparameters being fitted empirically.  相似文献

Payment by results is a relatively new way of giving development aid, where a recipient's performance against pre‐agreed measures determines the amount of aid they receive. Advocates for the mechanism argue it provides donors with both a ready justification for maintaining aid budgets and better results through innovation and autonomy. It has proved popular, with most bilateral aid donors having at least experimented with the mechanism and the variety of measures stretching from individual health workers being paid for each procedure, to national governments being paid for students' test scores. However, there has not been a robust assessment of whether Payment By Results (PbR) achieves its aims for greater effectiveness. I synthesize the evidence from eight projects fully or partially funded by DFID, the recognized world leader on PbR. This represents the best evidence currently available, and is critically analysed using the leading theoretical framework that breaks each agreement into its constituent parts. I find no evidence that PbR leads to fundamentally more innovation or autonomy, with the overall range of success and failure broadly similar to other aid projects. This may partly be due to the current use of Payment by Results, with no readily identifiable examples of projects that truly meet the idealized PbR designs. Advocates of PbR may thus conclude the idea is yet to be tested. I argue PbR does not deal with the fundamental constraints that donors face, and so it is unsurprising that PbR is subject to the normal pressures that affect all aid spending.  相似文献

People with serious mental disorders (PSMDs) are overrepresented both in prison deaths and during fatal encounters with the police in the community (deaths after police contact, DAPC). To identify common factors present across cases of who died during contact with the criminal justice system in Queensland, publicly available coroners reports were analysed (N = 38). The findings of the study indicated psychosis and mood disorders were the most common diagnosis in incarcerated PSMD deaths, and suicide was the most common cause of death for incarcerated PSMDs. Within incarcerated settings, access to healthcare records, medication compliance, risk assessment and monitoring, and safe housing of at‐risk prisoners may be potential areas to explore with regard to prevention. Similarly, PSMD DAPCs were more likely to be experiencing mood or psychosis disorders than other forms of mental disorder, and suicide and police shootings were the most common causes of death. In PSMD DAPC, inadequate mental health access, treatment noncompliance and comorbid substance use were included as potential areas that could direct research efforts toward prevention.  相似文献

Raising employment, in particular employment among older individuals and low educated individuals, stands high on the agenda of policy makers in many OECD countries. Increased sensitivity in recent years to rising inequality has made the challenge only larger. In this paper we evaluate alternative fiscal policy scenarios to face this challenge. We construct and use an overlapping generations model for an open economy where individuals differ not only by age, but also by innate ability and human capital. The model allows us to study effects on aggregate employment, per capita income and welfare, as well as effects for specific age and ability groups. We show that well-considered fiscal policy changes can significantly improve macroeconomic productive efficiency, without increasing intergenerational or intragenerational welfare inequality. Our results strongly prefer a reduction in the labor tax rate on older workers and on all low-wage earners, financed by an overall reduction in non-employment benefits. An alternative financing option is to raise the consumption tax rate. These results are to be seen as long-run effects for economies at potential output.  相似文献

片面地和局部地追求个人英雄主义的单极效应,已不是当今社会发展的方向和终极目标,更好地实现具有组织关系的人群最大效应策略将自觉或不自觉地成为了亘古不变的真理,因此人群整体效应的最优化势位法则的提出有其现实紧迫性和现实导向性。本文提出了以“势”作为描述人群组织关系的基本概念及对于不同人群组织关系中的势描述准则,并形成了人群组织关系的最优化势位法则。无论是大系统还是小系统的人群组织关系,这种势位法则都可用于实现该系统整体效应的全面提升。在信息和计算技术飞速发展的将来,这种势位法则对未来社会可能有着更加重要的影响和意义。  相似文献

1946年解放战争的爆发是由于国民党政府当时的刻板、僵硬的政治体制,是国民党政府未能建立一个能够适应不断变化的政治参政模式体制的必然结果。由于国民党政府无法为当时新的社会力量、新的上层分子提供参与政治的渠道和参与政治体系的机会,而当时被排斥于政治之外的社会力量、上层分子又具有参与政治的强烈愿望,这种政治体制和社会力量两种因素一但碰到一起,革命就会爆发。  相似文献

体制是连结生产力、生产关系和上层建筑的中介,它不仅可以反作用于社会基本制度,而且可以调整社会运行机制,规范社会发展秩序,协调社会健康有序地发展。体制和基本制度比较起来,对生产力的作用更直接;和人的思想觉悟比较起来,对生产力发展的影响面更广,影响程度更深,影响时间更长。  相似文献
