Ponds,Power and Institutions: The Everyday Governance of Accessing Urban Water Bodies in a Small Bengali City

While researchers in the growing field of urban political ecology have given significant attention to the fragmented hydroscape that characterizes access to drinking water in the global South, so far the (re)production of other urban waters and its related power relations have been underexplored. This article seeks to contribute to filling this gap by exploring the everyday negotiations over access to urban water bodies, in particular ponds. These are understood as a composite resource that is simultaneously water, land and public space. This analysis draws on a case study from a small city in West Bengal, India, and is based primarily on data from open interviews with different actors with a stake in urban ponds. The article demonstrates that in a context of ambiguity of the statutory governance regime and fragmented control, the (re)production of the pondscape is embedded within complex relationships of power whereby social marginalization can be offset at least momentarily by local institutions such as neighbourhood clubs and political parties.

Optimal model averaging forecasting in high-dimensional survival analysis

This article considers ultrahigh-dimensional forecasting problems with survival response variables. We propose a two-step model averaging procedure for improving the forecasting accuracy of the true conditional mean of a survival response variable. The first step is to construct a class of candidate models, each with low-dimensional covariates. For this, a feature screening procedure is developed to separate the active and inactive predictors through a marginal Buckley–James index, and to group covariates with a similar index size together to form regression models with survival response variables. The proposed screening method can select active predictors under covariate-dependent censoring, and enjoys sure screening consistency under mild regularity conditions. The second step is to find the optimal model weights for averaging by adapting a delete-one cross-validation criterion, without the standard constraint that the weights sum to one. The theoretical results show that the delete-one cross-validation criterion achieves the lowest possible forecasting loss asymptotically. Numerical studies demonstrate the superior performance of the proposed variable screening and model averaging procedures over existing methods.     

博弈论视角下的员工援助计划(EAP)策略研究

2010年伊始,中国东部沿海和部分内陆省份再度出现"用工荒",为了缓解劳资矛盾,提高企业效率,员工帮助计划(Employee Assistance Program,简称EAP)提上日程。在希望能更好的引导企业实施EAP的前提下,文章采用博弈论的方法从企业实施EAP障碍角度入手,分析了在完全市场环境与政府参与环境下企业实施EAP的行为与策略进行,得出政府的参与下能够使企业改变自身策略主动选择实施EAP。

金融危机背景下农民工就业能力研究

由美国次贷危机而引发的全球金融危机对日益融人世界经济体系的我国也造成了日渐严重的冲击,从2008年10月以来,已经有数百万的农民外出务工者由于工厂倒闭或歇工而被迫提前返乡。有关数据显示,中小企业吸收了我国就业农民工当中的75％,当一批中小企业在金融风暴中破产倒闭或者停厂歇业时,农民工就会收到最直接的冲击,农民工的就业出路就成了大问题。在金融危机造成严峻的就业形势下,如何提升外出务工农民的就业能力就成了至关重要的问题。
