Career Mobility in a Global Era: Advances in Managing Expatriation and Repatriation

The surge of interest in expatriation and repatriation within the broader discourse on labor mobility of professionals and high-skilled labor, human capital development, and the theory and practice of people management serves as the backdrop to this paper. We propose that expatriation and repatriation be framed in the context of global careers and embedded in the wider social-economic environment of globalization through the lens of a career ecosystem theory. We chart the evolution of scholarly publications on career mobility over the past four decades and highlight current trends, in particular the emergence of self-initiated expatriation as a pivotal change in the direction of expatriation studies and derived practice. We assess the rigor of empirical findings, weigh theoretical underpinnings, offer a research agenda for future research, and outline managerial implications.     

Semiparametric partially linear varying coefficient models with panel count data

This paper studies semiparametric regression analysis of panel count data, which arise naturally when recurrent events are considered. Such data frequently occur in medical follow-up studies and reliability experiments, for example. To explore the nonlinear interactions between covariates, we propose a class of partially linear models with possibly varying coefficients for the mean function of the counting processes with panel count data. The functional coefficients are estimated by B-spline function approximations. The estimation procedures are based on maximum pseudo-likelihood and likelihood approaches and they are easy to implement. The asymptotic properties of the resulting estimators are established, and their finite-sample performance is assessed by Monte Carlo simulation studies. We also demonstrate the value of the proposed method by the analysis of a cancer data set, where the new modeling approach provides more comprehensive information than the usual proportional mean model.

Sick building syndrome and perceived indoor environmental quality: A survey of apartment buildings in Hong Kong

The outbreak of a highly communicable disease, SARS, in Asia in 2003 has revealed the health risk of living in a high-density environment. To show the important connection between human health and environmental quality, this study surveys the prevalence of sick building syndrome (SBS) among apartment residents and their evaluation of indoor environmental quality (IEQ). Based on a sample of 748 households living in Hong Kong, two interesting findings are revealed: (1) nasal discomfort was the commonest home-related SBS symptom despite the absence of any central ventilation system in apartment buildings; (2) noise, rather than ventilation, was the major IEQ problem perceived by residents. Our statistical analysis further showed that residents with SBS symptoms were less satisfied with their IEQ than those without. That is, despite a positive evaluation of specific IEQ criteria with respect to the building residents lived in, if they reported feeling SBS related symptoms, the overall IEQ evaluation of their building could still be negative. This perception bias gives rise to a sample selection problem in measuring perceived IEQ, which has implications on housing management practices and the formulation of a healthy housing policy.     

论民商法原则对企业立法的规制

文章探讨了民商法原则对企业立法的规制.企业作为独立市场主体资格具有正常的行为方式,企业的行为必须是自益行为、自主行为和与企业组织形式相应的行为,国家管理不能取代社会调节功能,民事责任对于企业行为规制的基础性作用不容忽视.     

Family Control and Stock Market Reactions to Innovation Announcements

Although family firms are common around the world, studies on family‐controlled business are limited. Prior studies mainly focused on the influences of family ownership on overall firm performance, and the results were mixed. In this study we attempted to explore the impacts of family ownership on innovation by examining the association of family control and stock market reactions to innovation announcements. We found that firms with greater family control experienced significantly more negative stock market reactions to innovation announcements. The results further indicated that divergence of cash flow and voting rights was strongly and negatively correlated with announcement‐period abnormal returns. In addition, the findings suggested a significantly positive moderating effect of institutional ownership. The conclusions were robust under various measures of family control, and remained valid after controlling other influential factors for stock market reactions to innovation announcements.     

高校经济性腐败临界行为及机理研究

教育腐败危及公平和社会公信力，目前，高校腐败已经成为整个社会关注的热点。文章以博弈经济学的视角，分析了高校监督者和高校从业者之间的博弈关系，揭示了高校经济性腐败的临界行为，研究表明，高校从业者临界收益与监督概率、从业者收入、贴现因子及从业者任期正相关，与从业者风险好恶系数负相关，高校监督者临界监督成本与背德未被发现时收益、从业者收入、背德概率、贴现因子及从业者任期正相关，与监督者风险好恶系数负相关，在此基础上，提出应采取选择品德高尚的高校从业者、提高腐败成本、建立有效的监督和激励机制等预防高校腐败的措施。     

Social Development in Hong Kong: Development Issues Identified by Social Development Index (SDI)

Surviving the aftermaths of the Asian Financial Crisis and SARS in 2003, Hong Kong’s economy has re-gained its momentum and its economic growth has been quite remarkable too in recent few years. Nevertheless, as reflected by the Social Development Index (SDI), economic growth in Hong Kong does not seem to have benefited the people of the city at large as we see social qualities such as cohesion, security, equity, and empowerment are gradually eroded. This paper aims to summarize the current state of social development in Hong Kong based on the SDI-2008 and identify the major social, political and economic challenges that are confronted by Hong Kong. Based on the findings, a range of policy options proposed for promoting a more balanced approach to social and economic development are discussed. The article illustrates the utility of social indicators research such as the SDI in assessing quality of life and assisting related social planning initiatives in Asian communities such as Hong Kong.
