中国造船产业现状及走势分析

在世界船舶市场看好的情况下,中国采取大力支持、发展造船产业的政策,到2015年力争成为第一造船大国。这种预期导致了各地船舶工业投资过热和扩张过快的局面,造船能力几乎超出了国家规划的一倍,面临着产能过剩问题。同时各造船企业承接了大量订单,一旦船舶市场需求回落,将面临着严重的经济损失和资源浪费,应引起我们的警惕。     

转型发展时期代际公共品的供给困局及其破解

代际公共品是指超过一代以上的人分享使用的产品.其特点决定了它总是面临供给不足的困局.从总量上看,代际公共品供给不足;从结构上看,代际公共品的供求错位;从规范分析看,"好"的代际公共品供给不足.在转型发展这一场涉及社会各方面的深刻变革中,代际公共品的供求机制、供求格局都发生了根本性的变化,产生了新的困局.因此,充分认识代际公共品供求机制、供求格局的变化,正确发挥政府的职能,动员社会力量共同参与供给是破解上述困局的关键.     

布迪厄习性理论的五个核心性结构特征:德国的分析视角

本文在德国学界对布迪厄习性理论研究的基础上,重点梳理并分析了习性理论的五个核心性结构特征:第一,习性作为实践生成原则的通用性和统一性,第二,习性作为实践生成原则的规定性和自由度,第三,习性作为身体化的社会结构,第四,个体习性的多样性与阶级或群体习性的均一性,第五,习性与场域之间的本体论对应关系.通过引入德国学界对布迪厄的研究,本文希望能有助于我国布迪厄研究的知识积累与视域扩展.     

Exploring the Effects of Conditioning Factors on the Strain–Crime Association: A Test on Incarcerated Chinese Women

A key assumption of general strain theory (GST) is that various factors condition the effects of strains on crime. Past research examining this conditioning hypothesis tended to focus on youth samples and use gender as a control variable. Using survey data from Chinese female inmates, this study tests the strain–crime relationship posited in GST as well as the hypothesized effects of the conditioning factors. Regression results show that different types of strains have distinct effects on respondents’ odds to commit violent over property crimes. Conditioning factors are found to moderate the strengths of strains toward respondents’ likelihood to commit property crimes over violent crimes.     

Parenting Practices,Autonomous Motivation,and Adolescent Diet Habits

Guided by self‐determination theory, the aim of this study was to examine whether adolescents’ autonomous motivation for making healthy diet choices mediates the association between parenting practices regarding diet and adolescent food choices. We analyzed data from the NCI FLASHE study, a survey of demographically diverse parents and their adolescent children (N = 1,646 dyads). Path models supported self‐determination theory’s assertion that indirect, encouraging parenting practices fostered internal motivation; in contrast, regulation was both positively and negatively linked to motivation depending on the model. Models also yielded direct paths between parenting practices and healthy and unhealthy diet choices. Overall, regardless of what predicted motivation, adolescents’ autonomous motivation was linked with their consumption of healthier foods and drinks. As such, cultivating a sense of internal motivation during these formative years may put young people on a path toward healthy patterns of self‐regulation later in life.

Estimation of the additive hazards model with interval-censored data and missing covariates

The additive hazards model is one of the most commonly used regression models in the analysis of failure time data and many methods have been developed for its inference in various situations. However, no established estimation procedure exists when there are covariates with missing values and the observed responses are interval-censored; both types of complications arise in various settings including demographic, epidemiological, financial, medical and sociological studies. To address this deficiency, we propose several inverse probability weight-based and reweighting-based estimation procedures for the situation where covariate values are missing at random. The resulting estimators of regression model parameters are shown to be consistent and asymptotically normal. The numerical results that we report from a simulation study suggest that the proposed methods work well in practical situations. An application to a childhood cancer survival study is provided.

高管团队组成特征与行为整合关系研究

本研究运用公共组织、国有企业、民营企业和欧美外企等四类组织的325个高管团队样本,从行为视角探索了高管团队行为整合的结构和测量,重点研究了高管团队组成特征与行为整合的关系。实证结果发现,高管团队行为整合可分为决策参与、开放沟通和团队合作三个行为维度,高管团队规模、信任与高管团队行为整合变量显著相关。高管团队的多项异质性与行为整合显著负相关,这些异质性包括最高学历、海外学习考察时间、工作经历、每周工作时间、进入方式、团队任期、经营战略偏好等。     

品牌权益影响股东价值的实证研究

市场营销活动对企业股东价值的影响是品牌价值链研究的重要方面。近年来营销学者为了向企业经理证实营销活动能够为企业带来长远效益,不断探索各个营销环节和营销活动对企业股东价值的影响。从品牌的视角探讨营销活动对股东价值的影响,探索品牌权益对股东价值的影响途径和中介变量以及这些影响在不同行业之间的差异;以世界品牌实验室关于品牌价值评估的数据作为品牌权益的测量,以网易网站和东方财富网站的财务数据计算Tobin′sQ作为企业股东价值的测量,采用2005年～2007年的数据进行面板数据分析。研究结果表明,品牌权益能够正向影响股东价值,企业利润是品牌权益和股东价值的中介变量,品牌权益对股东价值的影响受企业所在行业的调节。
