<p>The development of open source software has gone from a model characterized by skilled software developers that developed open source software for their own interest and their own needs to a model that is more business friendly and more attractive for companies and organizations. One new business model for open source software is the professional open source software model or OSS 2.0. The business model includes three roles: the open source project, the professional open source company and the user. This dissertation studies the relationship between these three roles and focuses on the development of the user role and how it may develop for a new user in a specific OSS ecosystem.</p><p>The roles in the eco system that has been studied are taken by the open source project Alfresco, the professional open source company Redpill and a user from a large international company, without any previous experience of open source software or the business model of professional open source. The result of the study showed a well developed eco system between the open source project and the professional open source company but a need of more information about the user’s role in it. Open source software is still seen by the user as an unsafe and unsecure alternative to the proprietary software available and more information about the business model of professional open source software and how the user can interact and influence the eco system is still needed.</p>

The processes of transport and mixing in stratified open channel flows are investigated in this thesis. Detailed measurements of velocity and salinity were conducted, through the use of Laser-Induced Fluorescence (LIP) technique together with Laser Doppler anemometry, so that the effects of secondary current and stratification on the flow behaviour could be analysed. Two configurations were investigated: a rectangular open channel, and a compound open channel. For each configuration, four different stratification levels were analysed. The main flow characteristics, such as corner flow and velocity dip in a rectangular channel, and the twin vortices formed in compound channels, were found to be affected by stratification. In order to understand the mechanisms involved in secondary flow generation, the vorticity balance was carried out. Through the vorticity balance, the contribution of each term in the longitudinal vorticity equation could be evaluated. The mechanisms involved in the turbulence generation were also verified through the turbulent kinetic energy (TKE) budget. One of the contributions of this work refers to the understanding of the effects of stratification on turbulence and secondary flow generation. The exchange coefficients of momentum and solute were also investigated. These coefficients were found to depend not only on stratification level but also on other flow parameters, like for instance the aspect ratio. A new formulation is proposed for narrow channels, but more research is necessary in order to evaluate the effect of other parameters on the exchange coefficients.

This thesis reports on a study towards a sustainable open access scholarly publishing model in South Africa. The researcher defined the traditional scholarly publishing model as a foundation for scholarly publishing workflows and processes and the continuation of the publishing workflow as a sustainable business model. This model is simplified in this study to allow for further discussion in the investigation of the various business models of scholarly publishing. The researcher conducted a literature study to identify and define business models used in open access scholarly publishing in the international context and also developed a set of factors contributing to sustainability in this environment. These factors were then used to evaluate and investigate typical examples of open access role players in the South African context, using a desk study and interviews documented as case studies of the various initiatives. The researcher combined all these findings to make suggestions towards a sustainable open access scholarly publishing by identifying and exploring the various factors associated with open access models in South Africa, considering the roles of all the role players towards output of high quality research articles. The study found that South African scholarly publishers find the shift from a traditional subscription model to an open access model difficult, because they are not addressing their new client segment and also not acknowledging their own expertise within the publishing cycle.The research also indicates that the approach of either subscription or open access hinders a sustainable open access publishing model, but that the publishing community should instead encourage an approach a publishing environment that allows for both of these models to exist and function. Open access should not replace the traditional model but instead, enhance it. / Dissertation (MIS)--University of Pretoria, 2015. / Information Science / Unrestricted
