Performance Implications of IJV Boards: A Contingency Perspective

This study draws from the corporate governance literature to investigate the implications of board involvement for international joint ventures (IJVs). We extend recent corporate governance research on the value of board involvement by investigating unique sources of complexity related to the nature of the IJV. We argue and find that board involvement can enhance the performance of IJVs, particularly for collaborations that are complex in nature due to their broad functional scope as well the level of market overlap between IJV parents. We complement recent research on joint venture control that has focused on the antecedents and types of control, as well as studies on formal (e.g. contractual safeguards and monitoring) and informal governance mechanisms (e.g. trust) by providing empirical evidence that IJV board involvement is valuable when directors undertake their control and coordination responsibilities. We advance corporate governance research by providing evidence that joint ventures possess several unique characteristics that shape the value of board involvement, thereby showing that applications of corporate governance theory to joint ventures are useful, but should be made with care.     

CEO's empathy and salience of socioemotional wealth in family SMEs – The moderating role of external directors

A focus on preserving socioemotional wealth may influence entrepreneurial activities in family firms. In this paper, we identify the emotion of empathy in the family CEO as an antecedent of socioemotional wealth creation. We argue that the presence of one or more external directors can have a direct as well as moderating influence on the relationship between CEO's empathy and the salience of socioemotional wealth to the family CEO. Our empirical tests confirm these hypotheses. Several areas of future research are suggested to incorporate empathy and other emotions in family business studies.     

Formation of entrepreneurial intentions in a regional context

Research on the impact of the regional environment in the very early phase of the business start-up process is currently limited. This paper contributes to the literature by analysing the influence of regional factors on the formation of entrepreneurial intentions within the theory of planned behaviour (TPB) framework. The rationale is based on the previous literature which posits that regional conditions have implications for individual perceptions, which, in turn, constitute the foundation of the three antecedents of intention in the TPB model: attitudes, subjective norm and perceived behavioural control. A multilevel analysis based on a random sample of 834 Finnish working-age individuals, combined with the official national statistics at the municipality level supports the proposition that regional conditions have an indirect impact on the intent to become an entrepreneur. The population density, the level of education, income and wealth and the rate of public and manufacturing sector employment of a region are found to moderate the individual formation of entrepreneurial intentions. This study supports further development of the theoretical understanding of entrepreneurial intentions by demonstrating that regional characteristics are important moderating influences in the TPB model.     

Freedom of Association, Freedom of Contract, and the Right-to-Work Debate

The debate over union security arrangements is often presented as involving irreconcilable goals and values. Supporters of union security typically stress their importance to the union’s organizational strength and workers’ welfare. Right-to-work supporters, who favor banning such arrangements, typically emphasize employee freedom and choice. Our approach involves a unique comparison of both perspectives, which shows that neither perspective is completely compatible with safeguarding freedom. We therefore advocate reconciliation based on compulsory worker representation, which preserves the best freedom-enhancing properties of each perspective.

创新人格教育理论发展空间的再寻找

创新教育已经成为当前我国教育改革的基本理念,创新人格培养是其中很重要的一个环节。然而,当下的创新人格教育理论似乎难以解答当前在教育实践中碰到的许多问题,培养学生的创新人格也逐渐的沦为形式化。因此,本文在反思现阶段大学生人格危机问题的基础上,就创新人格教育理论的发展空间进行了三方面的路径的融合,国际视野的"重构"之路;本土文化的"考古学"之路;教育实践的"应变性"之路。本文就丰富和发展中国现有的创新教育理论,引领创新人格培养走出教育实践的困境具有重要的理论与现实意义。     

浅论两汉时期河湟羌人的种姓家支制度

两汉时期的羌乱给汉王朝带来了巨大的灾祸,是促使东汉灭亡的因素之一。除了共同的政治经济利益使河湟各羌落凝聚起来反对汉王朝对羌民的歧视和苛政外,其本身存在已久的种姓家支制度亦使河湟羌落间始终有种潜在的联系,也正是这种制度使得徙入塞内上百年的羌人仍与塞外的羌落间有着相同的认知,促进羌落间的聚合。因此种姓家支制度是种潜在的凝聚机制。汉王朝亦认识到羌人家支制度对其统治产生的威胁,也有意识的予以破坏。     

Memoryless Reigns of the “Sons of Heaven”

Human lifetimes have increasing failure rates; as people age (beyond early childhood) they are more likely to die. Viewing the succession of Chinese Emperors as a statistical ensemble we show that, unlike lifetimes, their reigns ceased at a constant rate for over two millennia, unaffected by elapsed time. In fact reign lengths of the “Sons of Heaven”, as the Chinese Emperors were known, followed a memoryless exponential distribution with a 10-year half-life. Becoming emperor not only influenced the duration of remaining life, but length of rule was independent of age at ascent. We propose an explanation for the observed exponentiality using asymptotic results from the theory of stationary stochastic processes.
