A framework for enhancing organisational performance through linkages between leadership style and organisational culture : the case of the South African Police Service (SAPS)

Masilela, Linkie Slinga 05 1900 (has links)
The aim of this study was to find the relationships between leadership style, organisational culture and organisational performance and subsequently develop a conceptual framework for enhancing Organisational Performance through the linkage between Leadership style and Organisational Culture in the public sector, in the South African Police Service (SAPS). Many of the previous studies have explored the direct relationship between specific culture domains and a specific performance measure and researchers have paid attention to mediators and moderators of the link between organisational culture and performance only in private sectors. According to the literature, leadership style and organisational culture have been independently linked to organisational performance (Ogbonna & Harris, 2000; Denison & Mishra, 1995; Xenikou & Simosi, 2006; Cameron & Quinn, 2011). All these authors focused on the effect of organisational culture and leadership style on organisational performance in the private sector. In order to achieve the research aim and objectives extensive an intensive literature review of the relevant and current literature was done. The mixed methods approach was applied. Data was collected by the use of self-administered questionnaires for the quantitative data and in-depth interviews and observations for the qualitative data. Regression analysis was used to investigate the relationships between the key study variables and more importantly the mediating and moderating effect on the effect of leadership style on organisational performance. The results of this study indicated that the transformational leadership style does not have a direct effect on organisational performance but rather through organisational culture as a mediating and moderating variable. It was also found that transformational leadership style and organisational culture affect each other. The implication was that leaders should cultivate an organisational culture which is conducive to work in order to enhance organisational performance. / Business Management / D.B.L.

The role of school managers in the implementation of continuous assessment in the further education and training band in Mopani district, Limpopo province

Ramalepe, Matome Liphy 11 1900 (has links)
This study focuses on the role of school managers in addressing challenges associated with the implementation of continuous assessment (CASS) in the Further Education and Training (FET) band in Mopani District. It furthermore investigates to what degree school managers in the district engage in performing the “traditional” leadership and management roles which create a conducive atmosphere for the implementation of CASS. A thorough literature review provides an understanding of the emerging trends and challenges in the implementation of CASS internationally. Most of these challenges are analogous with those constraining the implementation of CASS in Mopani District. The data were collected by means of semi-structured interviews and questionnaires from purposively sampled district educators and school management teams (SMTs) who came from randomly selected schools. The findings enumerated the insufficient training for school managers and infrequency of performing “traditional” leadership and management roles as some of the factors hampering the implementation of CASS in the district schools. / Educational Studies / M.

Market orientation and business performance : an empirical study of the banking sector in Ethiopia

Mulugeta Gebre-Medhin Kassie 09 1900 (has links)
The purpose of this study was to examine the relationship between market orientation and business performance mediated by marketing resources and moderated by contextual factors. The study also examined the extent to which the conceptual model was a good fit to the sample data. A quantitative approach was used to test if there was a significant relationship between market orientation, marketing resources, and business performance. For the purpose, a cross-sectional survey was carried out to obtain data pertaining to market orientation, marketing resources, contextual factors and business performance. The unit of analysis of the study was banks consisting of 3 public and 15 private banks. A sample size of 507 consisting of 492 branch managers and 15 top level marketing managers was used in the survey. With a response rate of 87.97%, 446 questionnaires were collected of which 377 were used for data analysis. A SEM was used to test the extent to which the theoretical model fits the sample data. Mediation analysis was used to test the indirect effect of market orientation on business performance and hierarchical regression analysis was used to test whether the relationship was moderated by market dynamism, competitive intensity, and government regulation. Finally, an independent t – test was used to examine the statistical variations between public and private banks in terms of market orientation, marketing resources, and business performance. The confirmatory factor analysis revealed that the modified model was fit with the observed data in terms of chi-square and the individual indices. The total effect of market orientation on business performance was moderate with a 0.36 regression coefficient. The indirect effect was high with a 0.91 regression coefficient where complete and inconsistent mediation was found due to suppression effect. The moderation analysis revealed that the interaction effect of market dynamism, competitive intensity, and government regulation was not statistically significant. Finally the result showed that there was a statistically meaningful difference between public and private banks in terms of market orientation, marketing resources, and business performance. Banks in Ethiopia shall strive to segment the market, differentiate their services, and build a strong brand with clear identity. Banks in Ethiopia shall also build on their marketing resources to enhance their business performance. / Business Management / D.B.L.

La médiation : une approche constructive à la hauteur des conflits de notre temps : un pont possible entre la justice et la paix dans un monde pluraliste / Mediation : a constructive approach to the conflicts of our time : a possible bridge between justice and peace in a pluralistic world

Graf, Kathrin 22 November 2017 (has links)
Ce présent travail a pour vocation de fournir une approche multidisciplinaire – historique, socio-politique, économique, et psychologique – pour comprendre l’intérêt général de la gestion constructive de conflit, et en particulier les opportunités liées à la méthode de la médiation. La thèse reflète le chemin parcouru - de la déconstruction à la reconstruction du sujet – débutant par une analyse théorique (les origines, les spécificités, les différences avec d’autres méthodes, les valeurs et principes), passant par une prise en considération des phénomènes individuels et collectifs inhérents au conflit et à sa gestion (les niveaux de conflit, les dimensions de la gestion, les fondements psychologiques individuels, les opportunités d’une démarche intégrative mais aussi les limites et risques liés à la méthode de médiation). Le travail tient également compte de l’évolution personnelle du chercheur, de sa pratique de médiateur, des échanges avec d'autres professionnels ainsi que ses constats de réalisabilité (conseils de mise en pratique, organisation logistique, outils concrets pour les différentes phases, et restitution des étapes clés d’un cas pratique).Mots clés : accompagnement, arbitrage, compréhension mutuelle, confidentialité, consensus, dialoguer, doubler, écoute active, empathie, facilitation de communication, gestion de conflit effective et constructive, impartialité, médiation, méthodes alternatives de règlement de conflit, modération, négociation intégrative, prévention/traitement auto-responsable de futures conflits, résolution créative de problèmes, solutions « pareto optimales », rétablissement de la paix, gestion des processus, rapprochement, réconciliation, science décisionnelle, supervision, zone d’accords possibles / This work aims to provide a multidisciplinary approach - historical, socio-political, economic, and psychological - to understand the general interest of constructive conflict management, and in particular the opportunities related to the method of mediation. The thesis reflects the path taken - from deconstruction to reconstruction of the subject - beginning with a theoretical analysis (origins, specificities, differences with other methods, values and principles) and considering the individual and collective phenomena inherent to each conflict and its management (levels of conflict, management dimensions, individual psychological foundations, opportunities of integrative bargaining, but also the limits and risks associated with the method of mediation). The present work also takes into account the personal evolution of the researcher, her practice as a mediator, exchanges with other professionals on this behalf and her personal findings of feasibility (practical advice, logistical organization, concrete tools for the various phases, and the restitution of the key steps of a practical case). Key words : active listening, alternative dispute resolution, arbitrary, communication facilitation, conciliation, confidentiality, consensus, constructive and effective conflict management, creative problem-solving, decision science, dialogue, empathy training, empowerment, Harvard negotiation model, impartiality, integrative bargaining, looping, mediative solutions, moderation, negotiation, “pareto optimal” solutions, peacemaking, process management, reconciliation, reframing, settlements, supervision, therapy, understanding, zone of possible agreements

A Cross-Cultural Study of Adult Attachment, Social Self-Efficacy, Familismo, and Psychological Wellbeing

Zamudio Leal, Gabriel Mario 08 1900 (has links)
Although Latinos are the largest minority group in the country, research examining how different psychological and cultural variables affect Latino individuals' wellbeing is disproportionately developed and cross-cultural comparison studies are particularly scarce. To address these issues, this dissertation research examined cross-cultural adult attachment-social self-efficacy-psychosocial wellbeing conceptual mediational model while investigating the moderator effects of country membership and familismo on the proposed mediational model using a cross-cultural sample of Mexican and Mexican-American university students. A total of 595 participants, including 360 Mexican students from Mexico and 235 Mexican-American students from the United States completed the research questionnaires. Results indicated that social self-efficacy was a significant mediator for the effects of insecure attachment on life satisfaction and conflict resolution in both cultural groups and for the links between attachment insecurity and depressive symptoms in the Mexican-American group. Additionally, moderated mediation analyses showed that country membership was a significant moderator for the links between attachment avoidance and social self-efficacy when life satisfaction, conflict resolution style, and depressive symptoms were the dependent variables, as well as for the direct link between attachment anxiety and physical health symptoms. Familismo was also found to be a significant moderator for the direct effects of attachment anxiety on physical health symptoms and life satisfaction in both groups. Findings are discussed from the attachment and cross-cultural perspectives. Counseling implications, limitations, and future research directions are offered.

AN EXPERIMENTAL INVESTIGATION AND CONDITIONAL PROCESS ANALYSIS OF THE ROLE OF CATASTROPHIZING IN THE PAIN—WORKING MEMORY NEXUS

Philip Matthew Procento (8083106) 05 December 2019 (has links)
There is a well-documented bidirectional relationship between pain and cognitive dysfunction, especially working memory. Despite this extensive body of research, the pain–working memory relationship is poorly understood. Pain catastrophizing – exaggerated negative cognitive and emotional responses towards pain – may contribute to working memory deficits by occupying finite, shared cognitive resources, but this has yet to be investigated. The present study sought to clarify the role of pain catastrophizing (assessed as both a trait-level disposition and state-level process) in working memory dysfunction. Healthy undergraduate participants were randomized to an ischemic pain or control task, during which they completed verbal and non-verbal working memory tests. They also completed measures of state- and trait-level pain catastrophizing. Mediation analyses indicated that state-level pain catastrophizing mediated the relationships of pain group to both verbal and non-verbal working memory, such that participants in the pain group (vs. the control group) catastrophized more about their pain, which then resulted in worse verbal and non-verbal working memory performance. In moderated mediation analyses, trait-level pain catastrophizing moderated this mediation effect for both verbal and non-verbal working memory. Those participants in the pain group who reported greater tendency to catastrophize about pain in general exhibited greater catastrophizing in-the-moment during the pain task, thereby leading to worse verbal and non-verbal working memory performance. These results provide evidence for pain catastrophizing as a putative mechanism and moderating factor of working memory dysfunction in pain. Future research should replicate these results in chronic pain samples, investigate other potential mechanisms (e.g., sleep), and develop interventions to ameliorate cognitive dysfunction by targeting pain catastrophizing.

The moderating effect of information security on the adoption of mobile marketing transactions among South African tertiary students

Donga, Gift Taruwandira January 2020 (has links)
PhD (Business Management) / Department of Business Management / Despite the fast pace of development within the mobile commerce industry globally, marketers in developing countries are still lagging in understanding why and how consumers participate in mobile marketing transactions. The literature reporting on mobile marketing transactions’ adoption in a South African context remains largely inconsistent and fragmented as most previous studies are based on the experience of consumers in a non-South African (and nondeveloping country) context. Therefore, this study identifies a literature gap, in that there lacks a sufficient critical mass of studies into the moderating effect of information security on consumer adoption of mobile marketing transactions in South Africa particularly among the youth who have a strong affinity for constant mobile connectivity. Furthermore, confronted with rapid changes in emerging technology, previous models of technology adoption are slowly becoming outmoded. Consequently, this study considered testing a proposed model on the predictive power of marketing-related mobile activity to help improve understanding and prognosis of the adoption of mobile marketing transactions in South Africa. Specifically, in order to render these tests robust, perceived information security was applied as a moderator variable to increase the explanatory power of the model. The objectives set out for this research were measured utilising a single cross-sectional approach, guided by the positivist paradigm. In keeping with the dictates of ensuring the highest levels of reliability and validity, a measuring instrument developed from past studies was used. Using a self-administered questionnaire, data were collected from a sample of 810 students from selected South African universities. Descriptive and multivariate statistical tests including the moderated hierarchical regression analysis were used to analyse data. The implication of the study is that it provides both marketers and policymakers with a set of controllable variables that may be manipulated to promote the adoption of mobile marketing transactions. / NRF

Dr. Georg Kühne: Der erste „Fernseh-Meteorologe“ der DDR kam aus Radeberg

Schönfuß, Klaus 05 February 2021 (has links)
Georg Kühne (1910 Ottendorf-Okrilla - 2001 Berlin) Das interessante Leben von Dr. Georg Kühne ist auf das engste mit der Entwicklung des Deutschen Fernsehfunks, dem Wettbewerbsbestreben zwischen den zwei deutschen Staaten Ost und West um die Vorreiterrolle dieses Mediums im gesamtdeutschen Konflikt zu sehen. Kühne wurde mit Einführung der bisher unüblichen Wettervorhersagen im Fernsehen zum ersten Ansager der täglichen Wetterberichte, im Anschluss an die „Aktuelle Kamera“. Der in Radeberg aufgewachsene Georg Kühne, Schüler am Radeberger Realgymnasium mit Realschule, absolvierte an der Technischen Hochschule Dresden sein Lehrerexamen, promovierte zum Dr. der Technischen Wissenschaften, darauf folgte ein Zusatzstudium zum Meteorologen. Diese Tätigkeit, unterbrochen durch die Kriegsereignisse, wurden ab 1949 in der Zentralen Wetterdienststelle Potsdam fortgesetzt. Hier wurde er zu einem der maßgeblichen Wissenschaftler auf dem Gebiet der Meteorologie, später der Erforschung der Klimatologie, in der DDR. Seine Leistungen führten dazu, dass er zum Leiter der „Zentralen Wetterdienststelle Potsdam“ (ZWD) berufen wurde. Dieses hohe Amt hatte er bis zum Beginn seines Ruhestandes 1975 inne.
