一战时期驻法华工教育与工人政治意识觉醒

一战时期,大量华工赴法从事战地、后勤等工作.在此期间,接受了大量有形和无形的教育,其中的扫盲教育、工业技能教育和政治教育帮助华工们产生了工人政治意识.这个意识的形成又是以罢工和建立工会组织的工人运动所体现的,并且深刻影响了中国近代史的发展.     

Hybrid Evolutionary Algorithms for Graph Coloring

A recent and very promising approach for combinatorial optimization is to embed local search into the framework of evolutionary algorithms. In this paper, we present such hybrid algorithms for the graph coloring problem. These algorithms combine a new class of highly specialized crossover operators and a well-known tabu search algorithm. Experiments of such a hybrid algorithm are carried out on large DIMACS Challenge benchmark graphs. Results prove very competitive with and even better than those of state-of-the-art algorithms. Analysis of the behavior of the algorithm sheds light on ways to further improvement.     

‘Ties that Bind’: A Transactional Approach to Social Capital

Abstract

The last decade has witnessed a renewed interest in the concept of social capital. However, much confusion still exists about the exact meaning of social capital. Thus, to create a foundation for future studies on social capital, this article develops a conceptual and theoretical framework to depict the stocks and flows of social capital. As such, it defines social capital formation in transactional terms so as to exploit fully the capital analogy used to characterise social capital and to place the concept of social capital on par with fixed, financial and human capital.     

‘The nice culture and the good behaviour’ state media and ethnic minorities in Lào Cai province,Vietnam

In the northern highlands of Vietnam, a very specific official vision of culture is at the core of the modernisation projects of Vietnam Television VTV5 (?ài Truy?n hình Vi?t Nam), a channel dedicated to educating ethnic minorities, and of the Lào Cai provincial branch of the Ministry of Culture, Sports and Tourism (MCST, B? V?n hóa, Th? thao và Du l?ch). These two state institutions jointly organise film screenings – for instance condemning the production and consumption of opium and heroin – in remote villages where they intend to modify cultural practices. These state social actors also produce films that represent what are deemed exemplary minority traditions for public consumption. Our observations of these media processes lead us to suggest that the subjects of these exogenous initiatives are adjusting strategically, activating patterns of quiet resistance to maintain their identities and subvert marginalisation.     

Total work and gender: facts and possible explanations

Time-diary data from 27 countries show a negative relationship between GDP per-capita and gender differences in total work—for pay and at home. In rich non-Catholic countries, men and women average about the same amount of total work. Survey results show scholars and the general public believe that women work more. Widespread average equality does not arise from gender differences in the price of time, intra-family bargaining or spousal complementarity. Several theories, including ones based on social norms, might explain these findings and are consistent with evidence from the World Values Surveys and microeconomic data from Australia and Germany.     

Management innovation: a dynamic analysis of the implementation phase over time

Abstract

We develop management innovation theory, providing insights into the role of time in the implementation phase. The management innovation literature has sought to empirically identify factors that facilitate or hinder management innovation implementation from a static perspective. To address the evolution of these factors’ resistance, a temporal perspective is appropriate, but an analysis of these factors’ evolution over time is lacking. We identify the inhibiting factors that influence the management innovation implementation phase over time and address ways in which they evolve.We conduct a comparative longitudinal and dynamic analysis based on two intermediate-sized enterprises and address the obstacles that emerge during the implementation phase of a specific management innovation: lean manufacturing. Our results highlight different categories of inhibiting factors: some inhibiting factors appear at the beginning of the implementation phase with high intensity and then fade over time; conversely, other inhibiting factors appear later and then increase in intensity.     

Work-related episodic memories can increase or decrease motivation and psychological health at work

ABSTRACT

Research on the psychological mechanisms underlying employee motivation and psychological health at work has been limited to general and chronic workplace factors, such as job strenuousness or management style. In two studies, we examine how unique and time-specific work life events encoded as episodic memories can influence employee motivation and psychological health at work as a function of how these events are recalled having been experienced in terms of need satisfaction. In Study 1, participants described a self-defining work-related memory and rated it for need satisfaction. They also completed scales of need satisfaction at work, self-determined motivation, and positive and negative indicators of psychological health (i.e. work satisfaction and burnout). In Study 2, participants completed the same tasks and scales, but they did it again two years later. Results revealed that need satisfaction in self-defining work-related memories was associated with self-determined motivation and indicators of psychological health at work, over and above demographics (age, sex, weekly hours worked, education) and general perceptions of need satisfaction at work. Moreover, it predicted increases in self-determined motivation and in work satisfaction and decreases in burnout over two years. The present findings underscore the importance of considering unique work life events encoded in memory.     

Disruptions in tightly coupled supply chain networks: the case of the US offshore oil industry

Managers have paid increasing attention to the exposure of their supply chains to disruptions and seek ways to mitigate supply chain vulnerability. The interconnectedness of tightly coupled supply chain networks makes this a challenging task, because interconnectedness and tight coupling of nodes in the network lead to an amplification of the actual risk exposure. This phenomenon can be attributed to the propagation of losses through the network, which exhibits certain dynamics. In order to investigate this mechanism, we studied the complex supply chain network of the oil industry in the Gulf of Mexico. Our results provide an estimate of the economic impact of eventual random and hurricane-related disruptions and can be used as a decision support tool for risk management of supply disruptions in interconnected supply chain networks.     

The informed society: an analysis of the public's information-seeking behavior regarding coastal flood risks

Recent flood risk management puts an increasing emphasis on the public's risk perception and its preferences. It is now widely recognized that a better knowledge of the public's awareness and concern about risks is of vital importance to outline effective risk communication strategies. Models such as Risk Information Seeking and Processing address this evolution by considering the public's needs and its information-seeking behavior with regard to risk information. This study builds upon earlier information-seeking models and focuses on the empirical relationships between information-seeking behavior and the constructs of risk perception, perceived hazard knowledge, response efficacy, and information need in the context of coastal flood risks. Specific focus is given to the mediating role of information need in the model and to the differences in information-seeking behavior between permanent and temporary residents. By means of a structured on-line questionnaire, a cross-sectional survey was carried out in the city of Ostend, one of the most vulnerable places to coastal flooding on the Belgian coast. Three hundred thirteen respondents participated in the survey. Path analysis reveals that information need does not act as a mediator in contrast to risk perception and perceived knowledge. In addition, it is shown that risk perception and perceived hazard knowledge are higher for permanent than temporary residents, leading to increased information-seeking behavior among the former group. Implications for risk communication are discussed.
