- Description: This study is an investigation of terrorism as a contributory factor to state failure in Somalia with specific reference to Al-Shabaab, using Huntington‟s Clash of Civilizations theory. It utilises both primary and secondary sources of data. The study found out that Somalia had been a failed state even before the birth of Al-Shabaab. However, the activities of Al-Shabaab perpetuated state failure in Somalia. These activities included bombings, small arms attacks, executions, siege, kidnappings, hijackings and looting. The study also found out that Al-Shabaab regularly conducted incursions in neighbouring countries and all these activities destabilised Somalia politically and perpetuated state failure. However, the study also found out that there were other factors that contributed to Somalia‟s state failure some of which were clan rivalry, civil war, warlordism, piracy, poverty and religion. Despite all these, the study noted that there were various actors involved in containing the terrorist activities of Al-Shabaab. These actors included the Transitional Federal Government, Kenya, the African Union, the United Nations and the United States. The study recommends that dialogue between the TFG, the clan structures and Al-Shabaab is the most viable path to sustainable peace in Somalia.

Teachers’ practices of ‘cooperative learning’ instructional technique in six schools: Implications for learner performance in Mathematics

- Description: One of the key features of curriculum change in South Africa in the last twenty years has been a move away from teacher centred instructional techniques to those that promote active participation of learners in their learning. Although the post democratic National Curriculum Statement has put emphasis on the importance of cooperative learning as a learner centred instructional technique, there is hardly any research on how teachers in schools understand and use it. This study sought to fill this gap by using a case study of seven mathematics classes in six schools. Data was collected through interviews, observations and document analysis.

Text data analysis for a smart city project in a developing nation

- Description: Increased urbanisation against the backdrop of limited resources is complicating city planning and management of functions including public safety. The smart city concept can help, but most previous smart city systems have focused on utilising automated sensors and analysing quantitative data. In developing nations, using the ubiquitous mobile phone as an enabler for crowdsourcing of qualitative public safety reports, from the public, is a more viable option due to limited resources and infrastructure limitations. However, there is no specific best method for the analysis of qualitative text reports for a smart city in a developing nation. The aim of this study, therefore, is the development of a model for enabling the analysis of unstructured natural language text for use in a public safety smart city project. Following the guidelines of the design science paradigm, the resulting model was developed through the inductive review of related literature, assessed and refined by observations of a crowdsourcing prototype and conversational analysis with industry experts and academics. The content analysis technique was applied to the public safety reports obtained from the prototype via computer assisted qualitative data analysis software. This has resulted in the development of a hierarchical ontology which forms an additional output of this research project. Thus, this study has shown how municipalities or local government can use CAQDAS and content analysis techniques to prepare large quantities of text data for use in a smart city.

The electrical, structural and elemental analyis of degraded single junction amorphous silicon solar modules

- Description: This study focuses on the degradation of solar cells due to localized heat. A decrease in optical absorbance represents a huge problem because of long-term solar cell degradation, decrease in absorption coefficient and a reduction in solar cell conversion efficiency. This decreases the photo-generating current hence reduces the effective efficiency of the solar device. As such the electrical output decreases, this research investigates the reduction in a-Si:H modules maximum power and its light absorption and correlates this with hot spot formation. Infrared Thermography was used for mapping of the module temperature profile, while IR flying meter software was used to analyze the hot spot centre. Fourier Transform Infrared Spectroscopy (FTIR) was used for absorption characterization. The study was undertaken during outdoor deployment of five PV modules. This method was chosen so as to deduce the practical effect of hot spot formation on the module’s absorption ability. The results show a direct correlation between localized heat and absorption degradation and structural degradation (damaged) in a-Si:H.

- Description: The aim of this research was to assess whether and to what extent does work-family conflict (WFC) and job stress affect organisational commitment of the employees within the health department. The quantitative design was used for the purposes of this study and the sample consisted of 141 respondents from selected hospitals within the Nkonkobe Municipality. The cluster sampling method was used to select the hospitals and then the simple random sampling was used to select the sample from the cluster. Data was analysed using both inferential and descriptive statistical analysis such as SAS 9.1, T-test scale and The Pearson Correlation Analysis. The results of the study showed significant positive relationships between WFC and job stress. Also, both WFC and job stress showed negative relationships with organisational commitment showing that they affect the commitment of workers. These findings are helpful and useful to the health department in implementing policies and procedures that will reduce WFC and job stress in employees in order to ensure that high levels of commitment towards the organisation are maintained for optimal success.
