Leadership styles, need satisfaction and the organizational commitment of Greek managers

This article presents the results of an empirical study of the relation between the leadership styles, need satisfaction and the organizational commitment of Greek managers. The findings show that there is a negative relationship between need satisfaction and organizational commitment. This relationship is stronger for the higher-order than for the lower-order needs. Furthermore, the results provide some empirical evidence regarding the relationship between the superior's leadership style and the subordinate's organizational commitment. The findings show that in most cases studied, the commitment of the Greek managers was higher when the superior adopted a consultative leadership style. This style was also the one preferred by the majority of our respondents.Greek managers leadership satisfaction commitment

A profile of the greek manager -- A survey

He was born in 1938 in Southern Greece. His father was self-employed. He is married and completed graduate studies in Economics/Commercial sciences. He has had previous experience in the Accounting/Finance function and strongly believes that this area consists the fastest route "to the top". He believes that the basic traits leading a person to success in management are creativity, desire for responsibility, concern for results and ambition, while the fundamental skills and knowledge enhancing his career are sound planning, communication, leadership, organization and methods. He does not consider such traits as integrity, patience, honesty, and such skills as working in groups, learning capacity, analytical thinking as very significant for his route towards the top. Who is he? A Greek senior manager, as depicted out of a recent survey. The foregoing is his sketch.

Correlates To Export Involvement Of Manufacturing Firms In A Less Industrialized Country

Over the past twenty years, considerable attention has been paid to the export behavior and performance of firms. A large share of the literature dealing with this matter consists of empirical studies whose purpose has been to identify the profile of exporting firms, in order to estimate the export potential. Although the environment is the same for all firms within a certain country, some distinguish themselves as exporting firms while others, do not. Thus a fundamental question arises: in what ways do exporting firms differ from non-exporting ones? This paper concludes that the distinction between exporting and on-exporting firms as a clear cut dichotomy is insufficient, and that a firm’s export activity is, to a large extent, related to its international competitiveness. This is especially true for countries such as Greece, where domestic markets are rather limited

Computational representation and hemodynamic characterization of in vivo acquired severe stenotic renal artery geometries using turbulence modeling

The present study reports on computational fluid dynamics in the case of severe renal artery stenosis (RAS). An anatomically realistic model of a renal artery was reconstructed from CT scans, and used to conduct CFD simulations of blood flow across RAS. The recently developed Shear Stress Transport turbulence model was pivotally applied in the simulation of blood flow in the region of interest. Blood flow was studied in vivo under the presence of RAS and subsequently in simulated cases before the development of RAS, and after endovascular stent implantation. The pressure gradients in the RAS case were many orders of magnitude larger than in the healthy case. The presence of RAS increased flow resistance, which led to considerably lower blood flow rates. A simulated stent in place of the RAS decreased the flow resistance at levels proportional to, and even lower than, the simulated healthy case without the RAS. The wall shear stresses, differential pressure profiles, and net forces exerted on the surface of the atherosclerotic plaque at peak pulse were shown to be of relevant high distinctiveness, so as to be considered potential indicators of hemodynamically significant RAS

Clinical indications for intravascular ultrasound imaging

Intravascular ultrasound (IVUS) is a catheter-based imaging modality, which provides high resolution cross-sectional images of the coronary arteries. Unlike angiography, which displays only the opacified luminal silhouette, IVUS permits imaging of both the lumen and vessel wall and allows characterization of the type of the plaque. Although IVUS provides accurate quantitative and qualitative information regarding the lumen and outer vessel wall, it is not routinely used during coronary angiography or in angioplasty procedures because the risk to benefit ratio (additional expense, procedural time, certain degree of risk, and complication versus improvement in the outcome) does not justify routine utilization. Nevertheless, there are situations where IVUS is extremely useful tool both for diagnosis and management so the aim of this review is to summarize the indications for IVUS imaging in the contemporary clinical practice
