Occupational attainment and stratification in China: The interactive effects of social networks and the hukou system

This paper examines the effects of social networks and hukou status on worker’s occupational attainment in China. To identify the potential ranking of different occupations, we consider the use of the stereotype ordered regression model to estimate individual occupational choice. Our results show that social networks play different roles in shaping occupational outcomes for urban and rural workers. In particular, friendship ties significantly improve urban workers’ opportunities in obtaining higher‐ranked occupations; in contrast, kinship ties appear to be more influential for rural migrants, but the effects are limited to the attainment of lower‐ranked occupations. While social contacts from government organizations or state‐owned sectors facilitate urban workers’ attainment of higher‐ranked occupations, similar patterns are not observed among rural workers. We further find that the beneficial effects of social networks or urban hukou identity are stronger for workers who are from less‐developed regions, who work in state‐owned enterprises, or who have a college degree. Decomposition of the wage gap between urban and rural workers suggests that differences in social networks and occupation types, together with hukou discrimination, account for the majority of the current wage inequality.     

Educational upgrading,structural change and the task composition of jobs in Europe

We analyze the changes in the task content of jobs in 24 European countries between 1998 and 2015. We link the O*NET occupational data with the European Union Labour Force Survey (EU‐LFS), and use the methodology of Acemoglu and Autor ( 2011 ). We find that the intensity of non‐routine cognitive tasks grew in all countries, while the intensity of manual tasks declined. Workforce upskilling was the major factor contributing to these developments. The intensity of routine cognitive tasks grew in most Central and Eastern European countries, but it declined in Western European countries. This difference is attributed to the contrasting patterns of structural changes in these groups of countries.     

Economization of Society: Functional Differentiation and Economic Stagnation

The explanation of economization and marketization processes is typically approached in the mindset of structural superiority, primacy or hegemony of the economic subsystem over non-economic spheres of social life. However, economic primacy is an underexplored puzzle for social theory from the perspective of functional differentiation theory, which emphasizes equal autonomy of social subsystems. Schimank has paved the way for theorizing economic primacy and economization pressures coherent with functional differentiation. Economization in his theoretical solution is connected to the economy’s governance mechanism—the market which is seen as having a weak order-building capacity. The contribution of this article lies in suggesting an alternative conceptualization of the internal dynamics of the economy—the stagnation tendency for explaining economization pressures as a systematic outcome.     

一般竞争战略理论论战、观点流派与研究展望——从割裂到融合

一般竞争战略理论对企业战略决策具有广泛而深远的影响。学者们对一般竞争战略的割裂观和融合观一直争执不休，众多研究呈现出多角度、多证据、结论矛盾和研究混乱的局面。文章通过对相关理论回顾和梳理，揭示出一般竞争战略理论割裂观存在的问题和困境，呈现融合观的理论与实证证据，提炼出混合战略的三个流派，并揭示混合战略研究的脉络和趋势。文章揭示出融合是竞争战略的趋势，实现不同战略类型的融合和竞争战略的多维体系构建，有助于厘清竞争战略研究的混乱和矛盾，打破根深蒂固的“骑墙战略”禁区思维，为企业的战略决策提供系统和多维的视角，并推动一般竞争战略从割裂化向融合化演进，特别是对现阶段的中国企业战略制定具有重要意义。     

中国城市居住分异的演化与特征

在对中国城市居住分异进行阶段梳理的基础上,分析现阶段城市居住分异的特点,认为居住分异在空间上已经由大尺度的分异转向大尺度混合、中等尺度的分异,即在城市尤其大城市的内城或近郊区都呈现各类收入阶层居住社区混合现象,楼盘(小区)成为当今城市新的居住分异单元;同时,中国居住空间分异的形成、演变与住房供给方式的发展、演变直接相关。     

清水江流域城市生态经济系统协调分异及耦合模式

研究清水江流域城市生态经济系统协调分异及耦合发展模式,可为岩溶城市规划与生态环境建设提供参考。通过构建耦合协调发展评价指标体系,运用熵值法与耦合协调模型对清水江流域2012-2016年城市生态经济系统协调水平、分异状态及耦合模式进行评价与分析。结果表明：城市生态经济系统协调发展经历了“中度失调—轻度失调—勉强协调—中级协调”4个阶段,耦合演进呈现“拮抗—磨合—高水平耦合”模式,当前城市生态经济系统耦合协调发展处于高水平耦合中级协调生态滞后状态;3个小城市生态经济系统耦合协调分异显著,其中福泉市综合水平较优、凯里市居中、都匀市滞后。在此基础上,提出了城市生态经济系统优质协调发展优化对策。     

Human Capital Factors Affecting Human Resource (HR) Managers' Commitment to HR and the Mediating Role of Perceived Organizational Value on HR

Human resource (HR) managers’ commitment to their occupation (HR) leads to the proper delivery and implementation of HR practices and, therefore, is deemed as a critical factor for the success of HR practices. Based on sociocognitive, human capital, and signaling theories, this study examines: (a) HR managers’ own and their chief HR officer's (CHRO) HR‐specific human capital as antecedents of their commitment to HR, and (b) the mediating mechanism through which the CHRO’s HR‐specific human capital positively influences HR managers’ commitment to HR. Based on 146 HR managers from 146 organizations in South Korea, the findings of the current study suggest that HR managers with higher levels of HR‐specific human capital and those working with CHROs with higher levels of HR‐specific human capital tend to have higher levels of commitment to HR. In addition, CHROs with higher levels of HR‐specific human capital positively influence HR managers’ commitment to HR by signaling to them that HR and its function are valued and cared about by their organizations. Theoretical and practical implications of this study are discussed along with study limitations and further research directions. © 2015 Wiley Periodicals, Inc.

A tool for analysing the interdependence of indoor environmental quality and reported symptoms of the hospitals’ personnel

The working environment and the working conditions can influence the well-being of hospital employees and consequently their performance at work. The present questionnaire-based study (737 valid questionnaires) developed and evaluated a quantitative structural equation model (SEM) that examines the interdependence between the indoor environmental quality (IEQ), the working conditions, the atopic constituents and the reported health complains of employees in three Greek hospitals. The results of the SEM reveal that IEQ could partially explain the employees’ symptoms in the hospitals. The working conditions proved to be a key factor in the relationship between IEQ and symptoms. Multi-group analysis has shown that this interdependence is affected by the building characteristics, by the gender, the smoking habits and the specialty of each participant, but not by their age.
