This study proposed and examined a model in which perceived organizational support and leader-member exchange are linked to safety communication safety commitment, and accidents. In addition, a moderating effect of role overload in the relationship between safety communication and safety commitment and that of performance monitoring in the relationship between safety commitment to accidents. Data were collected from 193 workers in a railroad company. The results indicated that the goodness of fitness of the proposed model was acceptable. More specifically, both perceived organizational support and leader-member exchange were significantly related to safety communication and safety communication was, in turn, significantly related to safety commitment which was ultimately related to accidents. Also, the moderating effects of both role overload and performance monitoring were found. Implications of these findings for safety and the possible roles of variables in the organizational level are discussed.

The research aims to explore the links among corporate governance, corporate social responsibility, and earnings management, considering vital roles of each component in Vietnam. There were 500 questionnaires provided to the targeted enterprises, where there were 150 enterprises in Ho Chi Minh Stock Exchange, 150 enterprises in Hanoi Stock Exchange, and 200 enterprises in the unlisted public company market. Of the distributed questionnaires, only 289 replies offered needed information for analyses. The data derived from these firms was based on their annual or sustainability statements that were retrieved from the websites. This research used a six-year rolling window to calculate earnings management. To compute that variable, lagged year information was included, so the data from 2011 to 2017 was needed to collect. The empirical results show that corporate governance mechanism is a significant moderation in the positive link between good corporate social responsibility and earnings management. Furthermore, corporate social responsibility and earnings management also play mediating roles in the associations among corporate governance, corporate social responsibility, and earnings management. This project recommends that corporate governance mechanism is an essential driver of the managerial behaviors in social responsibility and ethical accounting practices, which are in turn mediators in the joint research model.

This study examines the structure of intergenerational relationship and its effects on old-age security of the Korean society. Of interest is the effects of the middle aged's attitudes on old parents'security on their intergenerational exchange relationship and on their own old-age security as well. This study also attempts to test the applicability of the social exchange perspective to the study of intergenerational support relationship in Korea The social exchange perspective considers intergenerational relationship as an exchange of aids and rewards between generations. However due to strong norm of filial duty and inadequate welfare system, supporting old parents is regarded as younger generation's duty in Korea This study utilizes a survey data conducted by Kim et al.(2000). Major findings can be summarized as follows. First, the middle aged who gives one-sided supports to their parents tends to have the traditional attitude on old parents' security. It implies that intergenerational support relationship in Korea is not consistent with the explanations from the social exchange perspective. This study suggests a 'chained reward system'as an altermative explaining the intergenerational relationship. Second, an absolute majority of the middle aged tend to think that they are responsible for their own old-age security regardless of the pattern of intergenerational support relationship and attitudes on old parents' security. It implies that the middle aged in Korea holds the status of 'marginal men' who supports their parents but can't take the similar supports from their children.

This article tries to compare exchange relations between welfare and dictatorship in the East Germany and the North Korea. Unlike capitalist welfare aiming at correcting market results socialist welfare has been proposed to satisfy people's basic needs, but it had operated as instrument of dictatorship. Relation between welfare and dictatorship could be distinguished as hard exchange and soft one in line with social construction of welfare. Welfare-dictatorship relation in East Germany had developed from its formation(1949-1970s), crisis(1980s) and dissolution(1989-1990). There had established hard exchange relation in which the legitimacy of dominance had debted to welfare as social rights. While crisis of the exchange relation had been modest in a form of insufficient supply of consumption goods, it was one of the elements of collapse of dictatorship, leading to the unification with West Germany. The journey of the exchange relation in North Korea can be characterized by its formation(1948-1980), crisis(1990s-2000s), and transformation(2010s). Unlike East Germany, welfare was socially constructed as gift form the ruler to the ruled, which made the combination of welfare and dictatorship loosely coupled. Although economic crisis was severe compared to East German one the rulers have succeeded maintaining dictatorial dominance by creating dual exchange relation. They separated core group and subordinated one supporting the former at the expense of the latter. They blocked out most of the people from soft exchange relation making bad use of muddling-through life style dependent on market activities. This strategy led to a 'dictatorship neutral welfare extinction'. Taking the high degree of institutionalization of newly establishing welfare-dictatorship relation into account, lives of most people are hardly expected to be improved by gift by their rulers even if North Korean economy will recover in the future.

Social commerce, integration of social media and e-commerce, provides potential opportunities for consumers to talk about their ideas and exchange product-related information on online shopping platforms. Given the substantial prospects related to business opportunities and consumers' perceptions, this study explores the factors driving fulfillment of the psychological contract in social commerce platforms. This research proposes, examines, and proves a theoretical model for the post-purchase behavior of the consumers, through an empirical investigation of online questionnaire-based data, gathered from 367 consumers in a cross-sectional setting. Results show that the fulfillment of psychological contract, consumer loyalty, and affective commitment fully mediate the impact of consumer trust on platform and repurchase intention. The level of commitment toward the consumer by the platform is strongly related to the degree of consumer trust, which is reciprocated through re-purchase intentions. This study offers essential theoretical implications with regards to the social exchange theory, attribution theory, and an moderating effect of the platform empathy on consumers' trust-psychological contract fulfillment relationship. Likewise, this research has significant implications for practitioners and managers.

Recently, many companies have launched a new business model related to the mobile gift service in order to achieve or sustain a competitive advantage in the fast-growing mobile market. Due to the well combination of mobile technology advantages and offline gift-giving motivations, a mobile gift service has been proliferating over recent years. Although the motivation of mobile gift purchasing behavior can be different from that of offline gift purchasing behavior, there is still a lack of research on what factors are influencing and how they are impacting mobile gift purchasing behavior under diverse gift-giving settings. Therefore, based on both exchange and motivation theories as well as literature review, this study identified three influencing factors-economic (immediate rewards, convenience), social (friendship needs, reputation), and personal (enjoyment, self-satisfaction) benefits-and validated their impacts on intention to repurchase a mobile gift. Moreover, the moderating roles of intimacy and gift price in the relationships between benefits and mobile gift repurchasing intention were examined. The results provide many implications for marketing managers on how to enhance consumers' intention to repurchase, which in turn leads to sales and increased profit.
