哈耶克论“社会正义”

哈耶克的正义论是其自由主义的重要组成部分,在当代西方具有重要的影响。哈耶克通过他所理解的“社会正义”入手,在批判“社会正义”中,提出了他的正义观,充分显示了自由主义政治哲学的理论本质。虽然他的正义观并非尽善尽美,但他对“社会正义”的批判具有深邃的洞察力和深远的影响力。     

A Full Bayesian Non-parametric Analysis Involving a Neutral to the Right Process

Implementation of a full Bayesian non-parametric analysis involving neutral to the right processes (apart from the special case of the Dirichlet process) has been difficult for two reasons: first, the posterior distributions are complex and therefore only Bayes estimates (posterior expectations) have previously been presented; secondly, it is difficult to obtain an interpretation for the parameters of a neutral to the right process. In this paper we extend Ferguson & Phadia (1979) by presenting a general method for specifying the prior mean and variance of a neutral to the right process, providing the interpretation of the parameters. Additionally, we provide the basis for a full Bayesian analysis, via simulation, from the posterior process using a hybrid of new algorithms that is applicable to a large class of neutral to the right processes (Ferguson & Phadia only provide posterior means). The ideas are exemplified through illustrative analyses.     

Naming the Beast: Defining and Classifying Service Innovations in Social Policy

Over the last decade, the search for innovationhas become a core component of much social policyformulation and implementation. This search, however,has often been undertaken with little attempt to define the actual nature of innovation or to classifyits different modes. This paper reports recent researchwhich has developed a typologyof organizational changewithin which to situate and analyze innovation in social policy. It argues that thistypologyis an essential tool both for socialpolicymakers and for those concerned with itsanalysis.     

The environment as a determinant of child mortality among migrants in frontier areas of Pará and RondÔnia, Brazil, 1980

This article examines child mortality as an indicator of the quality of life among migrants living in Brazilian Amazonia in 1980. I focus on migrants in the frontier states of Pará and RondÔnia, which experienced rapid settlement during the 1970s. The key question here is the effect of settlement location on child mortality rates. While RondÔnia had lower ratios of population per public health establishments and personnel than Pará, RondÔnia nonetheless exhibited a higher malaria prevalence in 1980. I therefore attribute locational differences in child mortality to environmental factors important to malaria transmission rather than to health care infrastructure. The findings from multivariate regression analysis show that net of the effects of human capital, migration history and migrant living standards, settling in Pará rather than RondÔnia resulted in significantly lower rates of child mortality. These findings suggest that environmental factors coinciding with location of frontier settlement had important consequences for the living standards of migrants in the Brazilian Amazon.     

政治体制改革:中国特色社会主义的重要战略选择

政治体制改革是社会主义全面改革系统中的重要环节.在当代中国转型性发展的关键时期,尤其要高度重视和加大政治体制改革力度,充分发挥政治关系对于转型性发展的调节与保证作用.当前进一步深化政治体制改革,既要同经济体制改革深化和经济社会发展相适应,又要同大众政治参与积极性不断增强相适应,同时还要同中国特色社会主义政治发展的本质特征和科学内涵相吻合.深化政治体制改革,归根到底是要在适应时代新变化、实践新要求和人民新期待的基础上进一步拓展中国特色社会主义政治发展道路.     

Bayesian hierarchical regression models for detecting QTLs in plant experiments

Quantitative trait loci (QTL) mapping is a growing field in statistical genetics. In plants, QTL detection experiments often feature replicates or clones within a specific genetic line. In this work, a Bayesian hierarchical regression model is applied to simulated QTL data and to a dataset from the Arabidopsis thaliana plants for locating the QTL mapping associated with cotyledon opening. A conditional model search strategy based on Bayesian model averaging is utilized to reduce the computational burden.     

THE DIFFUSION OF MEDICAL TECHNOLOGY: SOCIAL NETWORK ANALYSIS AND POLICY RESEARCH

The purpose of this article is to demonstrate how social network analysis can be used to provide information for policy decisions pertaining to physicians' adoption and utilization of new medical technology. Interviews and hospital records were used to obtain data on refenals, consultations, discussions, and on-call coverage; utilization of a computer-based hospital information system; and personal and practice characteristics from 24 physicians who belong to a private group practice. The results of a block-model analysis suggest that the physician's relative position in the network is an important determinant of his/her participation in the diffusion process. A number of policy implications related to the introduction of new medical technology into practice settings are discussed.     

Efficiency and Power: Organizational Economics Meets Organization Theory

The disputes between sociologically informed organization theory and organizational economics revolve around the relative importance of efficiency and power. The concepts of efficiency and power are clarified in this paper, with distinctions being made between subjectivist and essentialist versions of efficiency, and between institutional and processual perspectives on power. Economists have largely ignored sociologists' discussions of power. It is argued that if path dependency is allowed for then organizational economics may well be compatible with an institutional view of power. The main theme of the paper is that efficiency is no less of an ‘essentially contested concept’ than power.

Contemporary urban culture: how community structures endure in an individualised society

This paper examines the ways in which socio-cultural norms have shifted to accommodate higher levels of autonomy in urban communities. Largely critiquing traditional concepts of community as well as current dystopian perspectives on the fluid and vapid state of social organisation, it will show how individualism has been incorporated into societal norms, producing highly autonomous personalised networks that, when combined with large amounts of social interaction and imaginative cultural appropriation, create the common social and cultural practices emblematic of community structure. It also illustrates how many activities, traditionally viewed as indicative of social decay, are socially productive, in that they go towards generating the common bonds and world-views that unite individuals across urban landscapes. Focusing particularly on the spaces of community interaction, the construction of common identities and common sense of belonging, this paper sets out to explore alternative modes of community creation and enactment in a contemporary urban environment.
