The western-based leadership and ethics literatures were reviewed to identify the key characteristics that conceptually define
what it means to be an ethical leader. Data from the Global Leadership and Organizational Effectiveness (GLOBE) project were
then used to analyze the degree to which four aspects of ethical leadership – Character/Integrity, Altruism, Collective Motivation, and Encouragement – were endorsed as important for effective leadership across cultures. First, using multi-group confirmatory factor analyses
measurement equivalence of the ethical leadership scales was found, which provides indication that the four dimensions have
similar meaning across cultures. Then, using analysis of variance (ANOVA) tests each of the four dimensions were found to
be universally endorsed as important for effective leadership. However, cultures also varied significantly in the degree of
endorsement for each dimension. In the increasingly global business environment, these findings have implications for organizations
implementing ethics programs across cultures and preparing leaders for expatriate assignments.

His research is aimed at understanding how people interact with and influence various aspects of their work environments,
including cultures, climates, leaders, and teammates along with the implications for various aspects of organizational behavior.
A particular focus of Christian’s work examines ethical leadership and the critical linkages between leadership and organizational
ethics. He received his Ph.D. from Wayne State University.

selection, test fairness, and racial/gender discrimination; and (c) research methodology. He is on the editorial board of
the Journal of Applied Psychology and The Leadership Quarterly and is a fellow of the Society of Industrial and Organizational
Psychology and the American Psychological Association.

Leaders,Values, and Organizational Climate: Examining Leadership Strategies for Establishing an Organizational Climate Regarding Ethics 总被引:4,自引:2,他引:4

This paper examines the critical role that organizational leaders play in establishing a values based climate. We discuss seven mechanisms by which leaders convey the importance of ethical values to members, and establish the expectations regarding ethical conduct that become engrained in the organizations climate. We also suggest that leaders at different organizational levels rely on different mechanisms to transmit values and expectations. These mechanisms then influence members practices and expectations, further increase the salience of ethical values and result in the shared perceptions that form the organizations climate. The paper is organized in three parts. Part onebegins with a brief discussion of climates regarding ethics and the critical role of values. Part two provides discussion on the mechanisms by which leaders and members transmit values and create climates related to ethics. Part three provides a discussion of these concepts with implications for theory, research, and practice. 相似文献

The short‐time asymptotic behavior of option prices for a variety of models with jumps has received much attention in recent years. In this work, a novel second‐order approximation for at‐the‐money (ATM) option prices is derived for a large class of exponential Lévy models with or without Brownian component. The results hereafter shed new light on the connection between both the volatility of the continuous component and the jump parameters and the behavior of ATM option prices near expiration. In the presence of a Brownian component, the second‐order term, in time‐t, is of the form , with d2 only depending on Y, the degree of jump activity, on σ, the volatility of the continuous component, and on an additional parameter controlling the intensity of the “small” jumps (regardless of their signs). This extends the well‐known result that the leading first‐order term is . In contrast, under a pure‐jump model, the dependence on Y and on the separate intensities of negative and positive small jumps are already reflected in the leading term, which is of the form . The second‐order term is shown to be of the form and, therefore, its order of decay turns out to be independent of Y. The asymptotic behavior of the corresponding Black–Scholes implied volatilities is also addressed. Our method of proof is based on an integral representation of the option price involving the tail probability of the log‐return process under the share measure and a suitable change of probability measure under which the pure‐jump component of the log‐return process becomes a Y‐stable process. Our approach is sufficiently general to cover a wide class of Lévy processes, which satisfy the latter property and whose Lévy density can be closely approximated by a stable density near the origin. Our numerical results show that the first‐order term typically exhibits rather poor performance and that the second‐order term can significantly improve the approximation's accuracy, particularly in the absence of a Brownian component. 相似文献

Die Leistungen der Unternehmenszentrale stehen h?ufig unter scharfer Kritik, da sie aus Sicht internationaler Führungskr?fte
die Treiber der Overheadkosten sind. Der Wertsch?pfungsbeitrag, den die zentralen Abteilungen erbringen, wird hingegen nur
selten diskutiert. Nur wenn zentrale Marketing- und Vertriebsabteilungen es schaffen, ihren Wertsch?pfungsbeitrag deutlich
zu machen und auch in Taten umzusetzen, kann die Existenz zentraler Abteilungen langfristig gesichert und Synergien realisiert
werden. Der folgende Beitrag zeigt, wie dies gelingen kann. 相似文献

The aim of this paper is to investigate the long run relationship between the development of banks and stock markets and economic growth. We make use of a Johansen-based panel cointegration methodology allowing for cross-country dependence to test the number of cointegrating vectors among these three variables for 5 developing countries. In addition, we test the direction of potential causality between financial and economic development. Our results conclude to the existence of a single cointegrating vector between financial development and growth and of causality going from financial development to economic growth. We find little evidence of reverse causation as well as bi-directional causality. We interpret this as evidence supporting the significance of financial development for economic development although banks and stock markets may have different effects depending on the level of economic development. 相似文献

Marketing managers and researchers generally agree that analyzing data from social networks and using them to influence consumers' purchase decisions are useful strategies. However, not all social network data may identify the most influential customers. This empirical study of more than 300 students reveals the low explanatory power of friendship networks (e.g., Facebook) and undirected-advice networks (e.g., LinkedIn). Only directed-advice networks (e.g., Google +) clearly identify influential consumers. In addition, the results challenge conventional wisdom that firms should target advisers assuming that they have the strongest influence on new product adoption. This study contradicts this common assumption and reveals that structural equivalence drives product adoption more than cohesion because advisees' adoption pressures advisers to purchase the product as well. Finally, the study shows the value of social network data beyond the traditional ego-centric psychographic metrics, such as innovativeness or opinion leadership. 相似文献

The article discusses the role of the UN Global Compact (UNGC) in the emerging global corporate social responsibility infrastructure. It evaluates the debate around the effectiveness and legitimacy of the UNGC alongside the arguments of its supporters and critics and thereby introduces the Thematic Symposium contributions. The article further identifies three theoretical perspectives that are used by scholars to discuss the performance of the UNGC: economic, socio-historical, and normative. It proposes that these perspectives can serve as generic distinctions with direct relevance for the evaluation of the UNGC. Once the perspective is chosen, it drives towards a certain purpose which implies assumptions and design features with regard to the UNGC. Finally, the article offers a future research agenda, emphasising the research needed on the UNGC in four areas: the identification of processes and influence mechanisms; legitimacy and effectiveness; local networks and regional development; and the interface of the UNGC and responsible leadership. 相似文献
