“知识整体理论”及其在管理领域中的应用

知识整体理论的提出是探索管理创新内在驱动过程中一次里程碑式的突破。该理论借以系统地阐发感性知识、理性知识和活性知识三者之间的实质性差异及动态关联而摆脱了长期以来管理中存在的窘境,并在"一分为三"的思维框架中彰显批判的反思与学习的辩证关联对于管理的作用。尤为重要的是,在以知识经济为时代特征的管理视阈,许多构建活动的研究和实践应用需要知识整体理论(尤其是活性知识)。诉诸于活性知识从批判性地学习径直通达人自身解放,是知识整体理论的重要洞见、应用及其在管理领域中的独特价值凸现。     

流迁人口对广东省人口发展的替代效应

所谓替代迁移是指迁移人口对长期处于更替生育水平以下的人口,因人口自然减少而产生的替代效用。广东省不但是全国人口流动和迁移最活跃的省份,而且人口总和生育率已连续10年低于更替水平,进入低生育水平时期。本文实证分析广东省在无流动人口、保持峰值人口、维持峰值劳动年龄人口和潜在供养比最大值等条件下,流迁人口对总人口规模和结构的替代效应,认为适度替代流迁人口是解决长期维持低生育水平地区所产生的人口问题的有效途径。     

The Effects of Media Usage and Interpersonal Contacts on the Stereotyping of Lesbians and Gay Men in China

Relatively little research has investigated the association of information sources and the stereotyping of homosexuals in other cultures. This study is a survey of 226 Chinese college students about their stereotypes of homosexuals and their sources of information on gays and lesbians. The stereotyping of homosexuals is predicted by the size of community, interest in knowing homosexuals, and in-person contacts. A higher level of negative stereotypes is associated with frequent usage of Chinese media.     

Ethical Leadership and Subordinates’ Occupational Well-Being: A Multi-level Examination in China

Prior research and managerial practices have often over-emphasized employees’ performance and ignored their occupational well-being. However, a series of employee suicide scandals in China have drawn people’s attention to employees’ occupational well-being and heightened the importance of how ethical leadership can enhance such well-being. Based on social exchange theory, this study examined the main effect of ethical leadership on subordinates’ occupational well-being in China, as well as the underlying mechanisms and contextual factors between them. Our sample comprised 302 employee questionnaires and 34 questionnaires completed by supervisors about their group. Using a multi-level approach, we implemented hierarchical linear modeling to examine the hypotheses. The results revealed that ethical leadership positively influenced the subordinates’ occupational well-being. This effect was partially mediated by distributive justice and interpersonal justice. Moreover, group level collectivism moderated the influence of ethical leadership on employees’ perception of distributive justice, interpersonal justice and their occupational well-being.     

Stochastic functional estimates in longitudinal models with interval-censored anchoring events

Timelines of longitudinal studies are often anchored by specific events. In the absence of the fully observed anchoring event times, the study timeline becomes undefined, and the traditional longitudinal analysis loses its temporal reference. In this paper, we considered an analytical situation where the anchoring events are interval censored. We demonstrated that by expressing the regression parameter estimators as stochastic functionals of a plug-in estimate of the unknown anchoring event time distribution, the standard longitudinal models could be extended to accommodate the situation of less well-defined timelines. We showed that for a broad class of longitudinal models, the functional parameter estimates are consistent and asymptotically normally distributed with a $\sqrt{n}$ convergence rate under mild regularity conditions. Applying the developed theory to linear mixed-effects models, we further proposed a hybrid computational procedure that combines the strengths of the Fisher's scoring method and the expectation-expectation (EM) algorithm for model parameter estimation. We conducted a simulation study to validate the asymptotic properties and to assess the finite sample performance of the proposed method. A real data example was used to illustrate the proposed method. The method fills in a gap in the existing longitudinal analysis methodology for data with less well-defined timelines.     

发展观、文明观的转变与环境法的修改

完善我国环境法的当务之急是调整环境法的立法目的。这是因为:第一,我国执政党和我国政府的发展观、文明观在2003年前后发生了重大的变化,与这种变化了的发展观、文明观相比,我国现行环境法所体现的发展观、文明观已经落后;第二,我国执政党和我国政府的发展观、文明观的改变是对人与自然关系的正确反映,而处理人与自然关系的主要法律部门是环境法;第三,要想让环境法适应发展观和文明观的转变,关键是对其立法目的做出修改。     

Permutation Methods for Comparing the Accuracy of Nested Prediction Models in Survival Analysis

When making patient-specific prediction, it is important to compare prediction models to evaluate the gain in prediction accuracy for including additional covariates. We propose two statistical testing methods, the complete data permutation (CDP) and the permutation cross-validation (PCV) for comparing prediction models. We simulate clinical trial settings extensively and show that both methods are robust and achieve almost correct test sizes; the methods have comparable power in moderate to large sample situations, while the CDP is more efficient in computation. The methods are also applied to ovarian cancer clinical trial data.     

Demographic Data on Syrians in Turkey: What do we know?

With the outbreak of civil war in Syria, Turkey has become the host of the largest refugee population in the world. In a country where reliable population registration systems are only recently established and where no extensive legal arrangements on migration existed prior to the Syrian crisis, the whole refugee situation was handled rather unsystematically, with ever-changing institutions and regulations, and various iterations of both. In this paper we present the demographic statistics that have been made public by different sources from the beginning of the crisis up to today because they are hard to reach in one place accompanied by relevant institutional changes; with the aim of assessing the current demographic data and revealing what is missing.
