The role of organizational culture in the relationship between leadership and organizational commitment: an empirical study in a Greek organization

Abstract: The aim of this paper is to explore the nature of relationships between organizational culture and leadership behaviours in affecting employees' commitment to their work organization. Building on organizational commitment literature, this study used a survey methodology. Empirical evidence was obtained from 300 employees working in a large Greek service company. The analyses indicated that the culture orientations examined served as mediators in the relationship between leader behaviour and followers' affective and normative commitment to the organization. The findings also indicated that continuance commitment is a two-dimensional construct; the ‘personal sacrifices’ dimension was found to be related to organizational culture and transactional contingent reward. This research paper has key messages for practitioners contributing to the fields of commitment, organizational culture, leadership and human resource management.

Intelligent modeling of e-business maturity

Abstract: E-business has a significant impact on managers and academics. Despite the rhetoric surrounding e-business strategy formulation mechanisms, which support reasoning of the effect of strategic change activities to the maturity of the e-business models, are still emerging. This paper describes an attempt to build and operate such a reasoning mechanism as a novel supplement to e-business strategy formulation exercises. This new approach proposes the utilization of the fuzzy causal characteristics of Fuzzy Cognitive Maps (FCMs) as the underlying methodology in order to generate a hierarchical and dynamic network of interconnected maturity indicators. By using FCMs, this research aims at simulating complex strategic models with imprecise relationships while quantifying the impact of strategic changes to the overall e-business efficiency. This research establishes generic adaptive domains – maps in order to implement the integration of hierarchical FCMs into e-business strategy formulation activities. Finally, this paper discusses experiments with the proposed mechanism and comments on its usability.

Forward jet production in deep inelastic scattering at HERA

Abstract: The production of forward jets has been measured in deep inelastic ep collisions at HERA. The results are presented in terms of single differential cross sections as a function of the Bjorken scaling variable (x_{Bj}) and as triple differential cross sections d^3 \sigma / dx_{Bj} dQ^2 dp_{t,jet}^2, where Q^2 is the four momentum transfer squared and p_{t,jet}^2 is the squared transverse momentum of the forward jet. Also cross sections for events with a di-jet system in addition to the forward jet are measured as a function of the rapidity separation between the forward jet and the two additional jets. The measurements are compared with next-to-leading order QCD calculations and with the predictions of various QCD-based models.
