Background
The aim of this study was to assess the prospective, longitudinal outcome after arthroscopically assisted open reduction and internal fixation (AORIF) and to compare the results with open reduction and internal fixation (ORIF) in complex ankle fractures.
Methods
Acute, closed, bimalleolar equivalent, bimalleolar, or trimalleolar ankle f...
Especially after complex ankle fractures, patients regularly suffer from residual symptoms, presumably due to occult intra-articular injuries. The aim of this study was to evaluate the intra-articular lesions, identify fractures specifically at risk for these, and assess the results after arthroscopically assisted open reduction and internal fixati...
Purpose
The purpose of this paper is to test the theoretical proposition, put forward by Yukl et al. (2002), that the leadership constructs of transformational and transactional leadership, laissez-faire, consideration, and initiating structure can be arranged into three meta-categories of leadership, namely, relations, task, and change-oriented le...
Introduction
Impaired ankle dorsiflexion (ADF) is known to increase forefoot pressure, which is associated to various pathologies affecting the foot and ankle. M. gastrocnemius tightness (MGT) is its most common cause. Up to date we are missing a standardized examination procedure, norm values, and a valid decision pathway to diagnose impaired ADF...
Background
Symptomatic extensor tendon irritation is a frequent complication in volar plate osteosynthesis of distal radius fractures. It is typically caused by dorsal screw protrusion and overdrilling of the dorsal cortex. The use of self-drilling locking screws (SDLS) could overcome both causes. The practical applicability of SDLS depends on two...
Purpose
– The purpose of this paper is to provide a comprehensive examination of different leadership constructs investigated extensively, namely transformational and transactional leadership, laissez-faire, consideration, and initiating structure, as well as leader-member-exchange. The theoretical overlap as well as the empirical correlations bet...
As an integrative research effort, the present study critically analyzed the relative importance of six leadership constructs—(1) transformational, (2) transactional, (3) laissez-faire, (4) consideration, (5) initiating structure, and (6) leader-member exchange (LMX)—as predicting indicators of leadership effectiveness in the for-profit versus the...
Recent theoretical and empirical research focused on the role of affect in the process of leadership. It was proposed that followers' interpersonal affect toward their supervisor biases the assessment of transformational leadership. In order to extend this work, the present study focused on other important, additional leadership constructs (i.e. tr...
Führungskräfte stellen Einflussgrößen dar, die wesentlichen Einfluss auf den Erfolg einer Organisation haben. Durch effektive Führung können bis zu 45 Prozent der organisationalen Leistungsfähigkeit erklärt werden. Gute und richtige Führung sollte sich dabei nicht ausschließlich an Leistungskriterien, Unternehmenszielen und Erfolgsmaßen ausrichten....
Purpose
The aim of this study is to contribute to the construct validity of leadership styles. Although several theories of leadership emerged in the past decades, integrative research on leadership constructs is rare. Thus, for the first time, the present study critically tests whether the leadership constructs of transformational and transactiona...
The well known constructs of transformational and transactional leadership are still facing problems concerning their discriminant validity as substantive correlations have frequently been observed between them. Nine samples, including 178 supervisors and their 834 followers, completed the German version of the Transformational Leadership Inventory...
Mehrere aktuell diskutierte Theorien erfolgreicher Führung werden gegenwärtig hinsichtlich kontextualer Einschränkungen kritisch hinterfragt und aufgrund empirischer Ergebnisse präzisiert. Jedoch erfolgt diese kontextfokussierte Forschung selten theoriegeleitet, da in der Führungsforschung bislang kein einheitliches System von Dimensionen der Organ...
Ziel des vorliegenden Beitrages ist, die Gutekriterien eines Instruments zur Erfassung von ethischer Fuhrung zu uberprufen. Ausgangspunkt war die Ubersetzung der Ethical Leadership Scale von Brown, Trevino und Harrison (2005) ins Deutsche (ELS-D). Anschliesend wurde anhand dreier Stichproben (N1 = 100, N2 = 119, N3 = 507) die faktorielle Binnenstru...
