The transformation from an industrial to a knowledge age has brought about a fast-changing world-focus and a competitive economy. The nursing profession, as part of the larger economy, is challenged by this transformation due to globalisation, internationalisation, capitalism within a consumer society, an ageing workforce, staff shortages, international migration and advanced technology. It is argued that these challenges are impacting directly on the nursing profession as a part of the global economy. This impact is intensified due to the ethos of nursing that is evaluated from a profit perspective and does not value the core values of nursing, that of caring and trust. The managerial strategies that are applied in nursing does not sufficiently harness and direct nurses. Focus is placed on nurse leaders as crucial role players in directing the nursing profession in peril. A call was made by followers for a different type of nurse leaders to lead this challenged profession, in an international arena. Social capital, being an abstract and multi-facet concept is presented as a possible framework to assist with the above crisis. Extremely limited literature was found on the utilisation of social capital to develop nurse leadership amongst these challenges. The research question, and later comprehensive aim, was formulated to examine how a theory in Nursing Science for authentic leadership embedded in a social capital framework, can be constructed. Theory construction of a middle-range theory was conducted in three phases. Phase One implied concept identification, descriptions, definitions and analysis. The actual theory construction was achieved in Phase Two, whilst Phase Three detailed the theory evaluation and guidelines for operationalisation. Main and related concepts were identified as agent, recipient, context, procedure, goal and dynamics. Data collection was conducted by means of a comprehensive literature search of all available national and international literature and included theories, textbooks and articles. Data saturation was achieved after no new information surfaced, n=188. The main concepts, authentic leadership (agent) and social capital (procedure) underwent a comprehensive concept analysis. Related concepts, namely the professional nurse (recipient), South African hospitals (context), positive impact on the triple bottom line (goal) and trust (dynamics) underwent a literature analysis. The theory was graphically portrayed and described by means of a model. The theory was submitted to a panel of experts (n=6). The panel was selected following purposive sampling due to specific inclusion criteria for expertise in social capital, and/or leadership and/or theory construction. The evaluation of the theory was conducted according to a specific framework for critical reflection. Guidelines for the operationalisation of the theory were formulated on a macro-, meso- and micro-level. The final step was the evaluation of the research and recommendations were made. / Thesis (Ph.D. (Nursing))--North-West University, Potchefstroom Campus, 2009.

The present study investigates the role of attachment in a time-limited marital therapy. The study explores Brief Contextual Modular Psychotherapy (BCMT). This approach to practice provides a model that integrates principles and techniques from the major psychotherapies. BCMT can be distinguished from other brief therapies by its theoretical integration, its six-session time limit, its specific clinical focus, and its techniques for dealing with dissatisfaction and distress. The therapy sets out practice modules—six-session treatment plans—for a diverse range of presenting issues such as the anxiety disorders, depression, trauma, loss and grief, marriage and the phobias. BCMT emphasises the collaboration of the therapist and the client. A community-based psychological counselling centre has practised BCMT for over ten years, applying it in cases of wide diversity and maladjustment. Prior to this research, a comprehensive analysis of the theory underlying the BCMT model or the theory of change it endorses had not been carried out. The study provides a detailed description of the conceptual and treatment elements of the marital module developed in the treatment manual for BCMT. The study explores how the construct of attachment provides an organising framework or metaperspective for theory construction and therapeutic intervention in the clinical application of this time-limited marital therapy. To achieve this objective, one de-facto and four married couples participated in the time-limited therapy. They completed a questionnaire on adult attachment and also a self-report questionnaire to assess the effectiveness of the therapy. Narrative analysis was used to assess the praxis or the experience of participating in the therapy. The results show that the integrated model provided a treatment method for differing expressions of marital disturbance and psychopathology. Three of the five couples and eight of the ten participants reported positive treatment outcomes. The research sample included the paraphilias, a major depressive episode with postpartum psychosis, the narcissistic borderline syndrome and childhood sexual abuse. The study supports the association between the role of adult attachment styles and intrapsychic responses in conflicted intimate relationships. From the point of view of clinical applications of attachment theory, the research highlights how theoretical ideas can be integrated, specific clinical methods can be incorporated and certain treatment perspectives can be derived from one another. Several implications for the treatment process flow from this integration. The integration of attachment theory in BCMT demonstrates how the therapeutic process progressed through three separate yet interrelated stages: past, present and future. In addition, it led to the identification of three stage-related mourning processes associated with the time-limited therapeutic process: protest, despair and detachment. From a clinical perspective, the research finds that the theoretical and treatment model does not need to be restricted to marital therapy. The findings suggest that the integrated model could be applied across a wide range of presenting issues. By defining the theory of personality and psychopathology and the therapeutic change processes associated with it, the integration of attachment theory results in BCMT taking its place in the literature as a theory of psychotherapy.

Building Information Modeling (BIM) has set up a mark in the construction industry over a decade. In order to gain benefit of BIM in estimating the project cost at the early stage of construction with the limited data available, a new concept of MacroBIM has been introduced in the industry. However, limited amount of research has been implemented to determine how MacroBIM has been accepted in the construction industry. Most research was focused on the accuracy of the conceptual estimation. This research attempted to determine the effectiveness of MacroBIM process applied at early stages of construction for conceptual cost estimation. Experts from the discipline of architecture, contractor and owners were interviewed and their professional opinions on MacroBIM were analyzed using grounded theory. The results show that, compared to the traditional conceptual estimating process, MacroBIM is an effective method for 1) saving labor hours, 2) conveying assumptions with the help of its visualization capabilities, 3) enhancing the collaboration among the project participants, and 4) evaluating multiple design scenarios. However, fear of using MacroBIM and trust in its outcome existed among some contractors, architects, and owners because this technology has not matured yet. Moreover, the need of interoperability between the MacroBIM tools and MicroBIM tools, such as Revit, has also surfaced in the study.

In dieser Dissertation beschäftige ich mich mit der Frage, welchen Anforderungen wissenschaftliche Theorien über Emotionen gerecht werden müssen, damit sie sowohl begrifflich fundiert als auch empirisch fruchtbar sind. Zu diesem Zweck biete ich zunächst eine Analyse der wichtigsten Herausforderungen, mit denen wissenschaftliche Emotionstheorien konfrontiert sind. Anschließend schlage ich einen metatheoretischen Rahmen vor, indem wissenschaftliche Konzepte von Emotionen als Begriffsexplikationen von Alltagsemotionskonzepten konstruiert werden können. Teil I diskutiert die wichtigsten Herausforderungen für Theorien der Emotionen in der Psychologie und den Neurowissenschaften. Die erste Herausforderung ist, dass eine wissenschaftliche Theorie der Emotionen alle und nur die Phänomene unter den Alltagsbegriff „Emotion“ subsumieren sollte, die durch gemeinsame begriffliche Ressourcen erfasst werden können. Die zweite Herausforderung ist, dass jede Emotionskategorie gut koordinierten Gruppen neuronaler, physiologischer und verhaltensbezogener Reaktionsmuster entsprechen sollte. Ich behaupte, dass keine der derzeitigen Theorien der Emotion in Psychologie und Neurowissenschaft dieser Anforderung entspricht. Infolgedessen ist eine neue Theorie der Emotionen erforderlich. Teil II entwickelt den metatheoretisches Bezugssystem für eine Theorie der Emotionen, die den oben genannten Herausforderungen entspricht. Erstens schlage ich eine pluralistische Darstellung der Kategorien oder „scientific kinds“ vor, die induktive Schlussfolgerungen begründen können. Jedes dieser Muster bietet einen Rahmen, um verschiedene Arten von wissenschaftlichen Konzepten zu konstruieren. Ich argumentiere, dass das funktionale Bezugssystem für wissenschaftliche Kategorien oder „scientific kinds“ am besten zur Erläuterung von Emotionskonzepten geeignet ist. Folglich schließe ich mit der Empfehlung, dass Wissenschaftler*Innen funktionalistische Theorien von Emotionen benutzen sollten. / In this dissertation, I address the question of how to construct scientific theories of emotions that are both conceptually sound and empirically fruitful. To do this, I offer an analysis of the main challenges scientific theories of emotions face, and I propose a meta-theoretical framework to construct scientific concepts of emotions as explications of folk emotion concepts. Part I discusses the main challenges theories of emotions in psychology and neuroscience encounter. The first states that a proper scientific theory of emotions must explain all and only the phenomena under the vernacular term ‘emotion’ with a common set of conceptual resources and under an overarching generic concept of emotion. The second demands that each emotion category corresponds to well-coordinated sets of neural, physiological, and behavioral patterns of responses. I argue that none of the best contemporary theories of emotions in psychology and neuroscience overcomes these challenges. As a result, a new theory of emotions is required. In Part II, I develop the meta-theoretical framework to construct a theory of emotions that overcomes the challenges above. First, I propose a pluralistic account of scientific kinds based on different patterns of projection that various disciplines may take to justify inductive inferences. These are essentialist, historical, and social patterns. Each of these patterns provides a framework to construct different types of scientific concepts. I argue that among the frameworks for scientific kinds available, the one that is best suited to explicate emotion concepts is a functional framework. Consequently, I conclude by recommending scientists pursue functionalist theories of emotions over essentialist, historical, or social theories.
