"空巢村"现象对新农村建设的影响

在我国经济社会发展过程中,具有较高素质的青壮年劳动力向城镇大规模转移,造成了"空巢村"现象的广泛出现."空巢村"现象给当前的新农村建设带来了劳动力缺乏、农民老无所养、农村基层党组织领导能力弱化等难题,为此必须改革农村耕地流转制度,鼓励农民工返乡创业,探索"以土地换保障"等农村养老的新模式.     

The Quality of Life of Hong Kong’s Poor Households in the 1990s: Levels of Expenditure,Income Security and Poverty

This paper examines the changes in the quality of life of poor households in Hong Kong in the late 1990s by analyzing their levels of expenditure, income security and poverty before and after 1997. Though there have been significant increases in the levels of expenditure among CSSA recipients, the expenditure among these poorest households in Hong Kong is still below that of non-CSSA recipients. Increasing poverty in Hong Kong is the result of increasing housing costs borne by these low expenditure households, who have to squeeze their expenditure on food and other items in order to meet the rising cost of housing. De-industrialisation and mass unemployment have given capital and the state unchecked authority to restructure the economy and to deregulate the labour market. Many low-income households have been hit hard as they faced redundancy, unemployment and wage-cuts after the 1997 Asian financial crisis. What jobs have been created are mostly part-time, temporary and contract jobs, and there has thus been an erosion in both job and income security. The quality of life of poor households is devastating not only in the sense that their living standards are low, but also that they are socially excluded from the mainstream of society.     

和而不同之“中”

“中”在中西哲学上占有相当重的分量 ,中国的儒道释和西方的亚里士多德都给予“中”以强烈关注 ,不同的是 ,儒家为道德之“中” ,道家为自然之“中” ,释家为性空之“中” ,亚里士多德为德性之“中” ,四家之“中”各有特色 ,“和”而不“同”。     

中国文学研究的困境与出路

采用新文学的观念 ,有系统的理论和科学的方法 ,来研究中国古代文学 ,是从 2 0世纪才开始的。从不同的层面对百年来的研究概况进行检讨就会发现 :就文学观念而言 ,散文和小说的分类观念至今尚未厘清 ;就理论系统而言 ,对传统的诗文理论 ,多泛泛模糊之谈 ,对外国理论则往往强加套用 ,给人浮薄无学的感觉 ;就研究方法而言 ,国学根柢越来越薄弱。要突破文学研究的这种困境 ,必须观念要厘清 ,理论要分明 ,方法要落实 ,根柢要深厚 ,还要加上“了解之同情”。     

A Sisterhood: The Collective Resilience Born in the Periphery of Prison

The collateral consequences of incarceration and prison visitation, transcend the boundaries of prison and transform women's lives. Through an intersectional approach, this research uncovers in what capacity degradation and secondary prisonization shape women's lives, and what coping mechanisms women form in response to the difficulties of visitation. Existing research has yet to identify visitors' relationships to one another and how these relationships aid in fostering coping strategies and resilience within the carceral realm. To fill the gaps, I employed qualitative research to explore the process of visitation, processing procedures, challenges of visitation, staff relations, and women's support systems. Findings indicated visitors are subject to an environment of gendered, racist, and classist oppression that varies in degree depending on social heirarchy and status. However, as a manifestation of resilience, women construct coping mechanisms in the form of information and support networks that aid in the dismantling the prevailing culture of scarcity of information and the degradation of free women by prison staff. These marginalized women habitually resist carceral domination through informal interpersonal support systems.     

Fast accelerated failure time modeling for case-cohort data

Semiparametric accelerated failure time (AFT) models directly relate the expected failure times to covariates and are a useful alternative to models that work on the hazard function or the survival function. For case-cohort data, much less development has been done with AFT models. In addition to the missing covariates outside of the sub-cohort in controls, challenges from AFT model inferences with full cohort are retained. The regression parameter estimator is hard to compute because the most widely used rank-based estimating equations are not smooth. Further, its variance depends on the unspecified error distribution, and most methods rely on computationally intensive bootstrap to estimate it. We propose fast rank-based inference procedures for AFT models, applying recent methodological advances to the context of case-cohort data. Parameters are estimated with an induced smoothing approach that smooths the estimating functions and facilitates the numerical solution. Variance estimators are obtained through efficient resampling methods for nonsmooth estimating functions that avoids full blown bootstrap. Simulation studies suggest that the recommended procedure provides fast and valid inferences among several competing procedures. Application to a tumor study demonstrates the utility of the proposed method in routine data analysis.

An Industrial Ocean-Cargo Shipping Problem

This paper reports the modeling and solution of an industrial ocean-cargo shipping problem. The problem involves the delivery of bulk products from an overseas port to transshipment ports on the Atlantic Coast, and then over land to customers. The decisions made include the number and the size of ships to charter in each time period during the planning horizon, the number and location of transshipment ports to use, and transportation from ports to customers. The complexity of this problem is compounded by the cost structure, which includes fixed charges in both ship charters and port operations. Such a large scale, dynamic, and stochastic problem is reduced to a solvable stationary, deterministic, and cyclical model. The process of modeling the problem and the solution of the resultant mixed integer program are described in detail. Recommendations from this study have been implemented.
