The development of leadership competencies index: the Economic Value Added (EVA) approach

Researchers posit that the primary objective of a business enterprise is to create shareholder value, and Economic Value Added (EVA) has been found to be the best available financial metric for measuring value. It is argued that EVA differs from other metrics in the sense that it incorporates both the enterprise profits and the capital costs for such profits. The study intended to establish attributes and competencies that are relevant, key and can bear the relationship with the EVA. In order to achieve this, the following questions were posed, namely; what key attributes and competencies an executive needs to possess for the purpose of organisational value creation?; and what is the measure to be utilised that includes these competencies to ensure organisational value creation and leadership development? The study aim was to propose and develop a diagnostic Value Creating Competencies Index, which is based on the components of or influenced by EVA. The success of the study was based on three pillars, firstly, EVA as a superior financial measure. To support this, literature that supported that EVA is adopted as a superior financial measure compared to other accounting based measures was reviewed and critiqued. The second element of the study was the focus on CEOs as critical and important drivers of value in organisations. However, the available literature was not able to provide a convincing argument to focus ‘all’ the attention on CEOs at the expense of other executives and the organisation at large. To determine whether CEOs can be given this attention and prominence, we conducted an additional study that assessed the share price movement on the public announcement of CEOs on companies listed on JSE. The findings of this study showed significant movement of share price and volume traded, and on the strength of this observation we concluded that CEOs can be used in this study as drivers of value. The third element was to look at competencies and competency modelling as a conduit that links value creation (EVA) and creators of value (CEOs). The literature on competencies was consulted and that of modelling, looking at the advantages and disadvantages of competency modelling. The study adopted a pragmatic paradigm and mixed methods approach. A qualitative dominant approach was followed. The study population consisted of Chief Executive Officers of the companies listed on the JSE top 40, who have had same position for a minimum of five years. Two CEOs could successfully be reached and interviewed. Data were collected through interviews, observations and documents analysis of the selected CEOs and their respective companies. Data were analysed qualitatively using the Atlas-ti software package, and then followed by a quantitative approach that was conducted using a Delphi approach. Two samples were utilised for this purpose. The first sample was a census of top 50 companies on Executive Search Review (United States headquartered companies that deals with CEO recruitments), the second sample was a random sample taken from JSE listed companies. Qualitative results were presented and discussed and the competencies were identified and linked to actual performance in respective organisations. In addition, identified competencies were confirmed by linking to the relevant quotations from the interviews and or analysed documents. Based on the qualitative results a competency model, Octastellatus CEO Competency model was developed and presented. From the competency model, the competency index Sustainable Economic Value Competency Index (SEVCI) was constructed and presented. The index has four clusters, namely; the core competencies, enabling competencies, differentiating competencies and competitive competencies. The index measure is presented as the sum of weighted averages of the four clusters. It is believed that this research work have made a significant and unique contribution by providing a quantitatively validated CEO competency model and corresponding competency index for assessing potential ability to create economic value. In an area that previously had a disconnection between ability to create value and actual value creation is now a known area and it is represented by SEVCI.Business ManagementDB

Distributed Technology-Sustained Pervasive Applications

Technology-sustained pervasive games, contrary to technology-supported pervasive games, can be understood as computer games interfacing with the physical world. Pervasive games are known to make use of 'non-standard input devices' and with the rise of the Internet of Things (IoT), pervasive applications can be expected to move beyond games. This dissertation is requirements- and development-focused Design Science research for distributed technology-sustained pervasive applications, incorporating knowledge from the domains of Distributed Computing, Mixed Reality, Context-Aware Computing, Geographical Information Systems and IoT. Computer video games have existed for decades, with a reusable game engine to drive them. If pervasive games can be understood as computer games interfacing with the physical world, can computer game engines be used to stage pervasive games? Considering the use of non-standard input devices in pervasive games and the rise of IoT, how will this affect the architectures supporting the broader set of pervasive applications? The use of a game engine can be found in some existing pervasive game projects, but general research into how the domain of pervasive games overlaps with that of video games is lacking. When an engine is used, a discussion of, what type of engine is most suitable and what properties are being fulfilled by the engine, is often not part of the discourse. This dissertation uses multiple iterations of the method framework for Design Science for the design and development of three software system architectures. In the face of IoT, the problem of extending pervasive games into a fourth software architecture, accommodating a broader set of pervasive applications, is explicated. The requirements, for technology-sustained pervasive games, are verified through the design, development and demonstration of the three software system architectures.

Innovation in Energy Security and Long-Term Energy Efficiency

The sustainable development of our planet depends on the use of energy. The growing population of the world inevitably causes an increase in the demand for energy, which, on the one hand, threatens the potential for shortages of energy supply, and, on the other hand, causes the deterioration of the environment.Therefore, our task is to reduce this demand through different innovative solutions (i.e., both technological and social). Social marketing and economic policies can also play a role in affecting the behavior of households and companies, by causing behavioral change oriented to energy stewardship, and an overall switch to renewable energy resources. This book provides a platform for the exchange of a wide range of ideas, which, ultimately, would facilitate the driving of societies to long-term energy efficiency

The Boeing / McDonnell Douglas and EADS mergers: ethnocentric vs. regiocentric consolidation in the aerospace and defence industry and the implications for international relations

This thesis relies on realist and neo-mercantilist approaches to explain the consolidation of the US and European aerospace and defence industry during the second half of the 1990s. Based on two case studies, the Boeing / McDonnell Douglas (BMD) merger in 1997 and the EADS merger in 1999, the thesis analyses the different political and economic motivations that led these aerospace and defence companies as well as their respective home governments to pursue either ethnocentric consolidation (in the case of the US) or regiocentric consolidation (in the case of France, Germany, and Spain) strategies. The BMD merger is interpreted as an attempt by the American hegemon to ensure that the important military, economic, and technological benefits derived from this strategic sector continue to accrue, above all, to the United States and its aerospace and defence industrial base. The cross-border EADS merger, in contrast, is viewed as a Franco-German-led counterbalancing attempt to guarantee the survival and autonomy of the European aerospace and defence industry, including Airbus, in the face of growing competitive pressures from the rapidlyconsolidating US mega-primes like Boeing. The thesis contrasts several high-profile transatlantic M&A deals in a variety of business sectors with the marked absence of similar transactions between US and European aerospace and defence companies. It thus highlights the strategic nature of this particular sector as well as American concerns about the proliferation of advanced US technologies to third countries, including to European NATO allies. Ultimately, realist and neo-mercantilist arguments prevailed over liberal-institutionalist / globalisation arguments among policymakers and business leaders on both sides of the Atlantic (especially in Washington, DC and Paris) – thus paving the way for the BMD and EADS mergers

Beneficiary perceptions regarding farm worker equity share schemes in South Africa

The study aimed to assess beneficiary perceptions regarding farm worker equity share schemes in South Africa. Farm worker equity share schemes started in the early 1990s with the aim of having a special arrangement pertaining to the ownership and operation of a farm between the farmer and the farm workers. This was intended to assist farm workers in not only remaining as farm workers but also to gain ownership of the farm. This could lead to the empowerment of farm workers, better working conditions, improved living standards and their rights to land ownership. Farm worker equity share schemes have been widely reported as having failed to meet their intended objectives, thus, in 2009, the Department of Rural Development and Land Reform initiated a study to assess the implementation of equity share schemes. Although the report was not made public, it reports that out of the 88 equity share schemes at the time, only nine managed to pay dividends ranging from R200 to R2000 per year. As a result, the Department of Rural Development and Land Reform put a moratorium on equity share schemes; this was however removed in 2011. It is against this background that this study was undertaken to assess beneficiaries’ perceptions regarding farm worker equity share schemes in South Africa. A positivistic research paradigm was employed in this study, by means of quantitative research. Secondary data in the form of textbooks, journal articles and Internet sources provided the theoretical framework for this study. Primary data was obtained using the survey method, by means of self-administered structured questionnaires. Convenience and purposive sampling were applied in order to select 20 farms that use equity share schemes. The farms selected for this study were located in the Eastern Cape, Gauteng, Mpumalanga and the Western Cape provinces, covering a variety of farming activities such as citrus fruits, crops, vegetables and wineries. Ideally, a total of 15 farm workers per farm were targeted. However, due to a variation in these farm worker equity share schemes, on some farms less than 15 workers and in others more than 15 workers were selected for the study; this resulted in a total sample size of 341 farm workers. Ten null-hypotheses and a hypothetical model of beneficiary perceptions regarding farm worker equity share schemes were tested. The influence of seven independent variables were tested, these are: stakeholder trust, operational risks, government interventions, two-way communication, farm worker empowerment, training and skills development, and access to resources on farm worker equity share schemes. In addition, the influence of farm worker equity share schemes on three dependent variables, namely, farming performance, sustainability and employee expectations were tested. The Statistica (version 13.2) computer programme was used to analyse the results by means of advanced statistical techniques (such as exploratory factor analysis, regression and correlation analyses) as well as descriptive analysis and frequency distributions. After various statistical procedures, the model was re-specified; some of the variables were then renamed and the hypotheses were adjusted accordingly. The empirical results showed that three key variables to the success of farm worker equity share schemes are stakeholder trust, government interventions and farm owner support. It was determined that these key variables could lead to increased farming performance, farming sustainability and meeting employee expectations. This study provided useful and practical guidelines to farm owners and administrators of equity share schemes, so as to ensure effective strategising that could enhance their competitiveness and long term survival. The findings of this study could inform strategy policy formulation and implementation in the agricultural sector, as pertaining to farm worker equity share schemes. The study used a sound and well-developed research design and methodology, which has been justified and successfully applied to this research; this method can be utilised by other similar studies to conduct empirical research in the field of farm worker equity share schemes. It is envisaged that the results and recommendations of this study could be used to implement effective strategies that could ensure the effective functioning of farm worker equity share schemes in South Africa

Disinvestment? Out of the question. Managing German business subsidiaries in apartheid South Africa during the tenure of P.W. Botha, 1978-1989

This thesis re-evaluates the case for business disinvestment from South Africa during the tenure of P.W. Botha (1978-1989). Using neglected corporate archives as well as oral testimony by former directors, the thesis scrutinizes the decision-making processes employed by the outlier on disinvestment – German business. Through seven case studies, the thesis illustrates how Apartheid policies, rather than being the foundation for business success, were the originators of enduring financial and operational woes. By continuing operations, management faced enduring uncertainty whilst grappling with the fallout from Botha’s reform and security measures. This research highlights that not only was international business entangled to an unprecedented degree with Botha’s policy agenda, but also that established narratives presented by anti-apartheid stakeholders on disinvestment require more critical evaluation. Most importantly, it illustrates that the ‘last decade of apartheid’ deserves a wider interdisciplinary approach that includes an engagement with the voice of management. For, these foreign corporate responses go beyond the historic South African context by having spearheaded several institutions, processes and interlinkages that define today’s globalised world

A Design Rationale for Pervasive Computing - User Experience, Contextual Change, and Technical Requirements

The vision of pervasive computing promises a shift from information technology per se to what can be accomplished by using it, thereby fundamentally changing the relationship between people and information technology. In order to realize this vision, a large number of issues concerning user experience, contextual change, and technical requirements should be addressed. We provide a design rationale for pervasive computing that encompasses these issues, in which we argue that a prominent aspect of user experience is to provide user control, primarily founded in human values. As one of the more significant aspects of the user experience, we provide an extended discussion about privacy. With contextual change, we address the fundamental change in previously established relationships between the practices of individuals, social institutions, and physical environments that pervasive computing entails. Finally, issues of technical requirements refer to technology neutrality and openness--factors that we argue are fundamental for realizing pervasive computing. We describe a number of empirical and technical studies, the results of which have helped to verify aspects of the design rationale as well as shaping new aspects of it. The empirical studies include an ethnographic-inspired study focusing on information technology support for everyday activities, a study based on structured interviews concerning relationships between contexts of use and everyday planning activities, and a focus group study of laypeople’s interpretations of the concept of privacy in relation to information technology. The first technical study concerns the model of personal service environments as a means for addressing a number of challenges concerning user experience, contextual change, and technical requirements. Two other technical studies relate to a model for device-independent service development and the wearable server as a means to address issues of continuous usage experience and technology neutrality respectively
