Abstract. In a sample of 73.56% response rate of 662 employees in 21 work units among 9 industries, across multiple organizations, by using questionnaire with convenience sampling and stratified sampling to get data collection, the relationship among servant leadership, voice behavior and self-efficacy were examined. Using SPSS 22.0 to conduct a statistical test, results support for our hypothesized models that (1) servant leadership will have positive impact on voice behavior (2) self-efficacy will mediate the relationship between ethical leadership and moral efficacy. These finding highlight the important role in explain why servant leadership can result in voice behavior. Theoretical and practical implications of these findings, as well as limitation and suggestions for future avenues are provided.

Abstract-In a survey with 73.56% response rate of 662 employees in 21 work units among 9 industries, across multiple organizations, by using questionnaire with convenience sampling and stratified sampling to get sample data, the relationship among ethical leadership, ethical climate and moral efficacy were examined. Using SPSS 21.0 to conduct a data analysis, we found support for our hypothesized models that (1) ethical leadership will have positive impact on moral efficacy (2) ethical leadership will be positively related to ethical climate (3) ethical climate will mediate the relationship between ethical leadership and moral efficacy. In the later, theoretical and practical implications of these findings and limitation, as well as suggestions for future avenues for researches and practice will be discussed.

Abstract. In recent years, social network theory becomes more and more significant in social science. Basing on the fast-growing social network theory, SNA (Social Network Analysis) is also widely used and published in different journals. As social actors are like nodes in the network, we use centrality to measure these nodes in power, activity and communication convenience etc.. Degree centrality, betweenness centrality and closeness centrality are main detailed measurement, and they have different algorithm. In SNA study, the research purpose determines the selection of centrality; and the use of these three centralities constitutes an important part in SNA study.

Abstract. Conducting a survey in multiple organizations (mainly in public utilities) in South China, with 73.56% response rate of 331 employees, by using questionnaire with convenience sampling and stratified sampling to get sample data, the relationship among ethical climate, moral ownership and moral efficacy were examined. Using SPSS 22.0 to conduct data analysis, we found support for our hypothesized models that (1) ethical climate will have positively impact on moral efficacy (2) Moral ownership can moderate relationship between ethical climate and moral efficacy, such that the relationship is weaker when moral ownership is high. In the later, we provide theoretical and practical implications of these findings and limitation, as well as suggestions for future avenues for researches and practice.
