Adoption versus use diffusion. Predicting user acceptance of mobile TV in Flanders

In the contemporary changing ICT environment, an increasing number of services and devices are being developed and brought to end-user market. Unfortunately, this environment is also characterized by an increasing number of failing innovations; confronting scholars, policy makers as well as industry with an explicit need for more accurate user research. Such research must result in more accurate predictions and forecasts of an innovation's potential, as a basis for more efficient business planning and strategy implementation. However, the success of a new technology is not only depending on the adoption decision and the number of people actually buying it, but relies at least as much on its actual usage. Hence, the focus of truly user-oriented acceptance or potential prediction should focus on predicting both adoption diffusion and use diffusion. Within this paper, we illustrate the added value of such an interactionist approach for the study of future adoption and usage of mobile TV by the assessment of both a large-scale intention survey and qualitative techniques such as diary studies, focus group interviews, observational and ethnographic methods

Power play in television: a political economy analysis of power balances in broadcasting markets

In this dissertation, the focus is on the (evolving) configurations of power and control in broadcaster-to-distributor markets. Technological developments, as well as changes in the institutional framework, are in the process of fundamentally transforming legacy TV business models and have transferred power to ‘gatekeepers’ which derive a dominant position by controlling competitive bottlenecks. Since technology shocks might disrupt established power relationships in television, interactions between TV broadcasters and distributors incur tensions and conflicts of interests. It is argued that each party controls crucial platform resources and that the broadcaster-to-distributor market is organized around two converging TV platforms that unfold enveloping strategies and thus provoke power conflicts. One of the major assumptions of this dissertation is the mutual dependency between broadcasters and distributors, which leads to the conclusion that the market is marked by bilateral bargaining power, and needs to deal with double-marginalisation problems. Although both parties may have bargaining power, relationships between broadcasters and distributors are often characterised by power asymmetries, either in favour of the broadcaster or distributor. In the ever-increasing complex TV ecosystem, broadcasters as well as distributors are looking for outside opportunities to lessen dependence on their counterparty, and build strategic advantage during carriage negotiations. However, pricing power usually remains with the distributors, which eventually decide about the possible carriage and the package (basic or upgraded), and the position of the channel in that package (or in the electronic programming guide). A gatekeeping position allows distributors to pressure broadcasters to demand lower wholesale (input) prices. On top, distributors leverage bargaining power through the ownership of affiliated channels that directly compete access-seeking broadcasters. In a similar vein, owners of premium rights or must-have channels leverage their popularity and exclusivity in order to bargain higher retransmission payments from distributors. Whereas existing frameworks hold that competitive advantage essentially rests on the activities a firm performs within the value chain, it is claimed here that a firm’s position in the value chain does not adequately explain why different firms with similar activities have different levels of bargaining power. Rather than sticking to hollow aphorisms like ‘Content is King, but Distribution is King Kong’, it is assumed that the allocation of power between broadcasters and distributors crucially depends on the politico-economic context of broadcasting and its distribution, including the set of complex relationships between different parties in the business ecosystem. Since bargaining power in the broadcaster-to-distributor market tends to be context-specific and varies between different local settings, it is determined by the allocation of scarce resources in the industry, the individual nature of the broadcaster-to-distributor relationship and potential path dependencies in media and telecommunication policies. Hence, the major research objective is to study the interactions between broadcasters and distributors, and identify, in a qualitative way, those contextual variables that define bargaining power in broadcaster-to-distributor relationships. Although Porter’s model is still relevant for analysing the industry environment, the complexity of broadcasting and distribution markets and the speciality of carriage negotiations demands for a more specific framework to examine relationships and power conflicts between broadcasters and distribution. Following a resource-centric perspective, the ownership and control of strategic assets are considered determinants of bargaining power. Based on a literature review and interviews with 36 media managers and experts, it was possible to come up with a multidimensional and multilevel approach to bargaining power and to construct a complex of interrelated power attributes (clustered in five dimensions) that influence a firm’s competitive position in carriage negotiations. On the macro level, a number of legal provisions and regulatory requirements strongly affect the carriage negotiations. Reference is made to telecommunications rules, competition law, media-specific regulation and copyright law. On the meso level, the model suggests that the market structure forms an important factor in the creation of bargaining power. Industry concentration, number of business partners, entry barriers and the threat of technological progress are identified as critical parameters. On the micro level, the structure of the negotiating firms needs to be taken into account to assess bargaining power. Hence, firm-specific characteristics of broadcasters and distributors involved in a carriage negotiation include relative firm size, conglomerateness, vertical integration and financial resilience. Next to firm characteristics, emphasis is put on product differentiation as a source of a bargaining power. Product characteristics are related to the market and industry structure, and predominantly refer to product differentiation, exclusivity, bundling and switching costs. On the individual level, psychological, emotional and interpersonal issues play a decisive role in carriage negotiations

A cloud business intelligence security evaluation framework for small and medium enterprises

Cloud business intelligence has practical importance in data management and decision-making, but the adoption and use among South African small and medium enterprises remain relatively low compared to large business enterprises. The low uptake persists irrespective of the awareness and acceptance of the benefits of Cloud business intelligence in the business domain. Cloud business intelligence depends on the cloud computing paradigm, which is susceptible to security threats and risks that decision-makers must consider when selecting what applications to use. The major objective of this study was to propose a security evaluation framework for Cloud business intelligence suitable for use by small and medium enterprises in small South African towns. The study utilised the exploratory sequential mixed-method research methodology with decision-makers from five towns in the Limpopo Province. Both qualitative and quantitative methods were used to analyse the data. The findings show that the level of adoption of Cloud business intelligence in the five selected towns was lower than reported in the literature, and decision-makers were eager to adopt and use safe Cloud business intelligence, but this was hindered by their inability to evaluate security in these applications. Factors preventing the adoption of Cloud business intelligence were decision-makers’ limited knowledge of the applications and security evaluation, the inability to use industry security frameworks and standards due to their complexities, mistrust of cloud service providers in meeting their obligations when providing agreed services, and lack of security specialists to assist in the evaluation process. Small and medium enterprises used unapproved security evaluation methods, such as relying on friends who were not information technology security specialists. A security evaluation framework and checklists were proposed based on the findings of the study and the best practices of the existing industry frameworks and standards. The proposed security evaluation framework was validated for relevance by information technology security specialists and acceptance by small and medium enterprise decision-makers. The study concluded that the adoption and use of Cloud business intelligence were hindered by the lack of a user-friendly security evaluation framework and limited security evaluation knowledge among decision-makers. Furthermore, the study concluded that the proposed framework and checklists were a relevant solution as they were accepted as useful to assist decision-makers to select appropriate Cloud business intelligence for their enterprises. The main contribution of this study is the proposed security evaluation framework and the checklists for Cloud business intelligence, for use by decision-makers in small and medium enterprises in small South African towns in the Limpopo Province.School of ComputingPh.
