A Quantitative Estimate of the Dominant Position of Public Ownership in China and Trends in Its Development

以不同生产资料所有制的经营性资产价值量作为衡量主次地位的边界标准，估算第一产业公有制与非公有制的资产规模及其比重变化，并在前人估算的基础上，延伸估算第二和第三产业两种所有制的资产规模及其比重变化。结果发现：截至2012年，中国三次产业经营性总资产约为487．53万亿元，其中公有制经济的资产规模是258．39万亿元，占53％；第二、三产业非公有制经济占增加值和就业规模的比重分别为67．59％和75．20％。这表明，公有制资产仍占主体，非公有制经济贡献占优，中国社会主义基本经济制度充满活力，从而为我国社会主义初级阶段的所有制改革和坚持“两个毫不动摇”的政策提供了理论依据。     

Accelerated life test sampling plans for the Weibull distribution under Type I progressive interval censoring with random removals

This paper considers the design of accelerated life test (ALT) sampling plans under Type I progressive interval censoring with random removals. We assume that the lifetime of products follows a Weibull distribution. Two levels of constant stress higher than the use condition are used. The sample size and the acceptability constant that satisfy given levels of producer's risk and consumer's risk are found. In particular, the optimal stress level and the allocation proportion are obtained by minimizing the generalized asymptotic variance of the maximum likelihood estimators of the model parameters. Furthermore, for validation purposes, a Monte Carlo simulation is conducted to assess the true probability of acceptance for the derived sampling plans.     

Robust block bootstrap panel predictability tests*

This article develops two block bootstrap-based panel predictability test procedures that are valid under very general conditions. Some of the allowable features include cross-sectional dependence, heterogeneous predictive slopes, persistent predictors, and complex error dynamics, including cross-unit endogeneity. While the first test procedure tests if there is any predictability at all, the second procedure determines the units for which predictability holds in case of a rejection by the first. A weak unit root framework is adopted to allow persistent predictors, and a novel theory is developed to establish asymptotic validity of the proposed bootstrap. Simulations are used to evaluate the performance of our tests in small samples, and their implementation is illustrated through an empirical application to stock returns.     

Bayesian analysis of multivariate stochastic volatility with skew return distribution

Multivariate stochastic volatility models with skew distributions are proposed. Exploiting Cholesky stochastic volatility modeling, univariate stochastic volatility processes with leverage effect and generalized hyperbolic skew t-distributions are embedded to multivariate analysis with time-varying correlations. Bayesian modeling allows this approach to provide parsimonious skew structure and to easily scale up for high-dimensional problem. Analyses of daily stock returns are illustrated. Empirical results show that the time-varying correlations and the sparse skew structure contribute to improved prediction performance and Value-at-Risk forecasts.

Diaspora Ownership and Homeland Firms' Internationalization

Although the contribution of diaspora to international business is becoming more evident, little is known about the channels used by individual firms to benefit from diaspora. In this paper, we propose equity ownership as a form of connection between the homeland firms and diasporans (i.e. diaspora members). Specifically, we draw on the literature on diaspora combined with an owners-as-resources perspective to theorize about how diaspora owners can affect the homeland firm's internationalization. We suggest that the anticipated entry costs deriving from the liability of foreignness faced by homeland firms explain how the impact of diaspora owners varies depending on entry mode. Finally, we compare diaspora owners to other types of foreign owner which we argue have lower levels of motivation and ability to help homeland firms to internationalize, and contribute relatively less to their internationalization than diaspora owners. We test and confirm our predictions using data on 2608 domestically controlled Indian firms and their internationalization in 2006–2012.     

Female Perceptions of Organizational Justice

This study examines women's conceptualization of the pervasive construct of organizational justice. A comprehensive four factor model was used to represent organizational justice while outcome variables were the important employee attitudes of job satisfaction, organizational commitment and turnover intentions. Structural equation modelling was used to analyse responses from 301 male and 147 female respondents. Differences were found for procedural, interpersonal and informational justices. It would appear female and male employees have differing responses to perceptions of justice. Justice had a diffuse effect for males, but not for females. For men, interpersonal justice predicted an increase in organizational commitment while procedural justice predicted a decrease in turnover intentions. For female employees, informational justice was found to increase commitment and reduce turnover intentions. The study highlights the need for all justice factors to be considered and for sex differences to be considered in future justice research.     

Coastal Adaptation Planning in Fairbourne,Wales: lessons for Climate Change Adaptation

ABSTRACT

Adaptation to climate change is emerging as a central objective and policy frame for coastal communities. This paper examines recent climate change adaptation efforts in the UK, centring on the case of Fairbourne, Wales. The village is facing the long-term prospect of flooding and inundation due to the impacts of sea level rise. The recent Shoreline Management Plan for the area has recommended realignment of the coast and eventual decommissioning of Fairbourne. The paper draws on a qualitative research methodology of interviews, policy review and observation to narrate the case and provide key insights and lessons for planners working in environmentally vulnerable coastal settings and managing climate adaptation processes.     

5-6岁幼儿分享行为和分享动机研究

本研究以厦门市某幼儿园的40名5-6岁幼儿为被试，运用实验法和访谈法，探讨“偶得物品”和“拥有性物品”下幼儿分享行为及其分享动机的特点。结果如下：（1）百分之百的幼儿具有正确的分享判断，但绝大部分幼儿并不愿意分享，“偶得物品”和“拥有性物品”之间的分享行为并没有明显差异。（2）愿意分享的幼儿中，被动分享占主导，其中一大部分是伪分享行为。（3）分享动机中，“同伴倾向”占主导，尤其是“偶得物品”的分享动机；“权威/规则倾向”和“移情倾向”也占有重要地位。     

墓券与东汉民众的生死观念

东汉时期的世俗民众没有认识到人终有一死的本质特性,反而抗拒死亡,渴求长寿永生。当年寿久长的愿望破灭时,他们又深信异象生命自然会在幽界冥府绵延不绝。不过生者却刻意疏远逝者,直接把殁亡人遣送到彼岸世界,希求幽鬼永居墓穴,接受冥府行政官僚体制和宗族观念的管制和束缚,按照世人的要求和期望去经历冥府生活。
