This study sought to analyse the influence of principal leadership on the performance of selected schools in the Gauteng Province of South Africa. The problems addressed in the research were what leadership and leadership styles in the school context entail, concept of school performance, attributes of leadership as perceived by principals and how these attributes impact on school performance and establish whether school performance is dependent upon principal leadership and his/her leadership style. It was a qualitative study. Stakeholders of the schools were interviewed and observations were made. The relationship between leadership and leadership style, in general, and school performance were investigated. The research established that unless principals were well equipped with knowledge and skills in management and leadership, they would not be able to improve school performance. / Educational Leadership and Management / M.

The study evaluates the perceived effectiveness of the leadership styles of deans in Ethiopian governmental Technical and Vocational Education and Training (TVET) colleges. The study was contextualised within the domain of relevant leadership theory in chapter 2 (with specific emphasis on the Full Range Leadership model developed by Bass and Avolio), and within the field of Technical and Vocational Education and Training in chapter 3. A mixed method research methodology was employed in the empirical research. The quantitative part received the most emphasis, while a qualitative part was added to attempt to corroborate findings. Quantitative data were collected from teachers (219), student council members (65) and deans (10) in ten TVET colleges using the MLQ 5x short-form questionnaire, which is a standardised questionnaire of high repute. The quantitatively collected data were analysed and presented using both descriptive and inferential statistics. The qualitative part consisted of semi-structured interviews conducted with the ten deans and one TVET Bureau Head. Quantitative findings indicated that the transformational and transactional leadership styles were observed far more frequently than the laissez-faire style. Perceptions regarding the effectiveness of deans, teachers’ job satisfaction and teachers’ willingness to make an extra effort were positively and statistically significantly influenced by the presence of both the transformational and the transactional leadership styles and to a slight extent, influenced negatively by the interaction effect of the two styles. Qualitative findings mostly corroborated the quantitative findings. Recommendations emanating from the research inter alia include: Leadership training opportunities for TVET deans should be scheduled to enhance the appropriate leadership style practice of deans (especially the transformational style); resources (human, financial and materials) should be made available to TVET colleges to develop desired types of leadership in colleges; as part of the selection process when appointing new TVET deans, the leadership style/s that applicants use at that stage should be assessed; a staff-dean-team-approach will be productive if the dean practises a transformational-orientated style of leadership. / Educational Leadership and Management / D.

Ledarskapsteori är ett viktigt ämne inom forskning, för att göra det möjligt att optimera prestation och trivsel hos medarbetare i organisationer. Det skapar även möjligheter för ledare att anpassa sig efter sina medarbetare och skapa trivsamma och produktiva arbetsplatser.   Denna studie undersöker sambandet mellan ålder och ledarskapspreferenser hos HR-anställda i Sverige. HR-anställda ansågs vara relevanta att studera då de har stor påverkan på hälsan hos alla anställda på en arbetsplats. Studien utfördes i form av en enkät som besvarades av 221 respondenter, där 21 frågor från instrumentet Multifactor Leadership Questionnaire, MLQ, besvarades. Frågorna mätte ledarstilarna Transformativt ledarskap, Transaktionellt ledarskap samt Laissez faire-ledarskap. Dessutom togs hänsyn till fyra olika generationsindelningar i studien; Baby Boomers, Generation X, Generation Y och Generation Z. Dessa representerar åldern på den arbetskraft som befinner sig på arbetsmarknaden idag.   Resultatet visade på ett negativt samband mellan ålder och preferens för transformativt ledarskap, vilket indikerar att yngre personer föredrar ledare som är mer transformativa i sitt ledarskap. Det fanns även samband mellan preferens för olika ledarstilar, vilket tyder på att en ökad preferens för en av ledarstilarna indikerar en högre preferens för ytterligare en ledarstil. Studien ställer sig kritisk till generationsindelningar, då det inte fanns några signifikanta skillnader mellan preferenserna hos individer från olika generationer. / Leadership theory is an important subject within research, to create information and knowledge of how leadership preferences can differ between individuals. It also creates an opportunity for leaders to adapt their leadership to different co-workers and create healthy workplaces.   The purpose of this study was to investigate the correlation between age and leadership preference in HR-employees in Sweden. HR-employees was considered to be relevant since they are accountable for the health of all employees at a workplace. A survey was conduced, where the 221 respondents answered 21 questions from the questionnaire Multifactor Leadership Questionnare, MLQ. The questions measured the leadership types Transformative leadership, Transactional leadership and Laissez-faire leadership. Four generations were also considered; Baby Boomers, Generation X, Generation Y and Generation Z, which represent the age of the workforce in Sweden at the time the study was conducted.   The study found a negative correlation between age and preference for Transformative leadership, which indicated that younger people prefer leaders who are transformative in their leadership. There were also correlations between preferences for different leadership types, where a higher preference for one leadership type also indicated a higher preference for another leadership type. The study is critical to dividing and judging people based on generation, since there were no differences between the preferences in individuals from different generations.

Les conséquences du leadership destructeur ont largement été documentées et étudiées; les impacts sur les subordonnés sont vastes et représentent un coût très important pour les organisations. Il en est de même pour le gestionnaire émetteur de ces comportements. Pourtant, on connaît actuellement un débalancement au sein de la littérature quant aux études recensant les conséquences versus les antécédents du leadership destructeur, alors qu’une meilleure compréhension des antécédents nous permettrait de pouvoir prévenir ces comportements. De plus, peu d’études se sont intéressées au vécu du gestionnaire lui-même et son contexte tel qu’il le perçoit ainsi qu’à la relation entre sa santé psychologique, plus précisément l’épuisement professionnel et ses comportements de leadership. Cette thèse cherche à fournir des éléments de réponses à ces lacunes à travers deux objectifs. Le premier objectif de cette thèse est de mieux comprendre comment un gestionnaire en vient à émettre ce type de comportements, entre autres à mieux comprendre la relation entre la perception qu’il a de son contexte de travail, son niveau d’épuisement professionnel et la fréquence à laquelle il émet des comportements de leadership destructeur en utilisant un modèle de médiation. Le second objectif est l’étude des ressources personnelles du gestionnaire et comment celles-ci peuvent faire une différence quant au niveau d’épuisement du gestionnaire. L’innovation de cette thèse réside dans son modèle intégrateur permettant de mieux comprendre la relation entre ces différentes variables et leur impact respectif sur le leadership. Pour ce faire, plus de 500 gestionnaires ont été interrogés sur leur contexte de travail, leur épuisement professionnel et leurs comportements de leadership. Des analyses de médiation modérée à l’aide du logiciel statistique « JASP » ont été réalisées. Les résultats indiquent un effet de médiation de l’épuisement professionnel entre les demandes psychologiques et le leadership destructeur, mais uniquement pour le leadership passif-évitant ainsi qu’un effet de modération des ressources personnelles. Plus particulièrement, les habiletés politiques modèreraient la relation entre les demandes psychologiques et l’épuisement professionnel, dans ce sens où plus un gestionnaire perçoit une charge de travail élevée, plus il aurait recours à ses habiletés politiques et pourrait vivre un épuisement professionnel supérieur à celui des personnes ayant peu d’habiletés politiques. Les principaux constats de cette étude doctorale sont discutés dans les prochaines pages et ce, à la lumière de l’état actuel des connaissances. Les contributions, les limites ainsi que les pistes de recherches futures qui en découlent sont également présentées. / The consequences of destructive leadership have been widely documented and studied. The impact on subordinates is vast and represents a very significant cost to organizations, as well as for the managers exhibiting such behaviors. However, the literature is currently missing key elements in terms of studies that observe the consequences of those behaviors versus their antecedents. If we are to prevent destructive behaviors, a better understanding of the antecedents is needed. Furthermore, few studies have focused on managers’ experiences and the contexts in which they perceive those experiences, or the links between managers’ psychological health—or more specifically, their exhaustion at work—and their leadership behaviors. This thesis aims to address these gaps in the literature through two objectives. The first objective is to gain a better understanding of how managers come to engage in destructive behaviors, including an analysis of the relationship between their perception of their work context, their level of burnout and the frequency with which they exhibit destructive leadership behaviors. The second objective is to study managers’ personal resources and their possible impacts on the level of burnout experienced. The innovation of this thesis lies in its integrative model which permits a better understanding of the relationship between these variables as well as their respective impacts on leadership. To this end, over 500 managers were interviewed about their work context, burnout and leadership behaviors. Moderated mediation analyses were performed using JASP statistical software. The results reveal that burnout has a mediating effect on the relationship between psychological demands and destructive leadership, but only in the case of passive-avoidant leadership, and that burnout has a moderating effect on personal resources. More specifically, political skills moderate the relationship between psychological demands and burnout, in that the higher a manager perceives their workload to be, the more they resort to their political skills, and they may experience greater burnout than those with lesser political skills. The main findings of this doctoral study are discussed in the following pages in the light of the current state of knowledge. Contributions, limitations and possible avenues for future research are also presented.
