Researchers have conducted many empirical studies on the positive effects of ethical leadership. However, they have paid little attention to the antecedents of ethical leadership. This study sought to fill this gap by examining the negative effects of leaders' perceptions of organizational politics on ethical leadership and the job performance of employees. Accordingly, this study investigated the relationships among them using data collected from 220 dyads of leaders and followers in major companies in South Korea. The results showed that leaders' perceptions of organizational politics negatively affected their ethical leadership, which, in turn, had an adverse impact on the task performance and organizational citizenship behavior of employees. This paper also provides the theoretical and applied implications of the findings as well as future research directions.
Entrepreneurs have been traditionally epitomized as rugged individuals garnering creative forces of innovation and technology. Applying this traditional, limited, and narrow view of entrepreneurship to ethnic firm creation and growth is to ignore or discount core cultural values of the ethnic contexts in which these firms operate. It is no longer possible to depend solely on human capital theory and household characteristic descriptions to understand the complex and interdependent relationships between the ethnic-owning family, its firm, and the community context in which the firm operates. This paper addresses the complex dynamic of ethnic firms with three purposes: (a) to provide a cultural context for the three ethnic groups composing the National Minority Business Owner Study; (b) to extend the Sustainable Family Business Theory, a dynamic, behaviorally-based, multi-dimensional family firm theory, by clarifying how it accommodates ethnic firm complexities within their cultural context, and (c) to derive implications for research, education and consulting with worldwide applications.
Six low-mass embedded sources (L1489, L1551-IRS5, TMR1, TMC1-A, L1527, and TMC1) in Taurus have been observed with Herschel-PACS to cover the full spectrum from 50 to 210 mu m as part of the Herschel key program, "Dust, Ice, and Gas In Time." The relatively low intensity of the interstellar radiation field surrounding Taurus minimizes contamination of the [C II] emission associated with the sources by diffuse emission from the cloud surface, allowing study of the [C II] emission from the source. In several sources, the [C II] emission is distributed along the outflow, as is the [O I] emission. The atomic line luminosities correlate well with each other, as do the molecular lines, but the atomic and molecular lines correlate poorly. The relative contribution of CO to the total gas cooling is constant at similar to 30%, while the cooling fraction by H2O varies from source to source, suggesting different shock properties resulting in different photodissociation levels of H2O. The gas with a power-law temperature distribution with a moderately high density can reproduce the observed CO fluxes, indicative of CO close to LTE. However, H2O is mostly subthermally excited. L1551-IRS5 is the most luminous source (L-bol = 24.5 L-circle dot) and the [O I] 63.1 mu m line accounts for more than 70% of its FIR line luminosity, suggesting complete photodissociation of H2O by a J shock. In L1551-IRS5, the central velocity shifts of the [O I] line, which exceed the wavelength calibration uncertainty (similar to 70 km s(-1)) of PACS, are consistent with the known redshifted and blueshifted outflow direction. ; LG Yonam Foundation Oversea Research Professor Program ; Herschel Open Time Key Project Program ; NASA through Jet Propulsion Laboratory, California Institute of Technology ; Basic Science Research Program through the National Research Foundation of Korea (NRF) - Ministry of Education of the Korean government NRF-2012R1A1A2044689 ; Sabbatical Leave Program of Kyung Hee Unviersity KHU-20131724, 20131727 ; Astronomy
