Options Under Uncertainty: An Empirical Investigation of Patterns of Commitment in Display Technologies in the Flat Panel TV Set Industry

This dissertation considers fundamental questions about real options reasoning and its application in the face of uncertainty: do firms behave as real options reasoning predicts, and are there performance benefits from its application? The concept of uncertainty is further developed by considering two primary types: technological uncertainty and market needs uncertainty. A qualitative industry level historical case study is performed on the flat panel TV industry, chosen because it exhibits high technological uncertainty and low market needs uncertainty. Real options logic predicts, in such an industry, that firms will develop and maintain technology options until uncertainty is resolved. Firm level case studies for major incumbent Japanese TV set manufacturers and other relevant firms are performed. Comparison across the cases, and between several specific firms is conducted to test and further develop theory. The firms studied are found to generally behave as predicted by real options logic. Evidence from the study does not present a clear relation between options-related behavior and performance. Although this study identifies evidence not holding options can have large negative performance results, firms holding options as predicted by theory did not realize lasting performance improvements. With one exception, firms attempting to leverage technological capabilities into improved market positions were unable to realize durable improvements in their positions. The development and release of flat panel TV coincided with changes in performance for many firms in the industry; however, these performance changes were short lived. By the end of the study period, industry players had generally returned to the trajectories they were previously on. Between-case analysis of several outlying firms in the sample provides a rich and nuanced view of requirements for firms to dramatically improve performance in the face of high technological uncertainty in a market with very large size potential and relatively well-understood customer needs. This research contributes to the empirical literature on real options and is novel amongst academic research in its coverage of the flat panel display history using Japanese sources. Finally, this dissertation includes managerial implications regarding the usefulness of real options reasoning as well as practical issues in its implementation

Rural secondary school teachers' experiences of job satisfaction and their expectations of support to develop their professional competencies as curriculum workers

Since the first National Curriculum Statement matriculation results for 2008, there has been an outcry that rural secondary schools in KwaZulu Natal are lagging behind in terms of pass rate compared to urban and former Model C secondary schools. There are various contributory factors that are impacting on poor learners’ performance in rural schools. This study was specifically conducted in rural secondary schools of KwaZulu Natal. The reason was that there is few research conducted in rural schools, particularly with regard to teacher job satisfaction and professional development. There is therefore a belief that satisfied teachers produce good performance in their schools. Furthermore, it is also believed that satisfied and adequately developed teachers are the key to successful implementation of the grades 10-12 National Curriculum Statement. The study was therefore conducted to investigate rural secondary school teachers’ experiences of job satisfaction and their expectations of support to develop their competencies as curriculum workers. The research problem was investigated through the mixed methods research. The use of mixed methods research was to ensure that reliability and validity are addressed. The concurrent strategy of mixed methods research was employed. In concurrent mixed research methods, data is collected during the same phase. Data was collected from rural secondary schools of Umzinyathi, Ilembe and Empangeni districts in KwaZulu Natal. There were fifty rural secondary schools which participated in the study. Four hundred rural secondary school teachers completed survey questionnaires. Eighteen rural secondary school teachers participated in individual interviews. Only nine rural secondary schools were involved in observation and interviews. Research findings show that poverty was one of the major contributory factors that led to poor performance of rural secondary schools. Poverty and lack of adequate professional development programmes in rural secondary schools have negative impact in terms of teachers’ job satisfaction. Learners’ poor command of English in rural secondary schools contributed to their poor academic performance. Lack of support services, bad condition of roads and, long distances travelled by both learners and teachers contributed to teachers’ job dissatisfaction and learners’ poor performance. Rural secondary school learners were demotivated about learning, since they lacked role models in their communities. Rural secondary school learners were also undisciplined. They bunked classes. They carried weapons to schools. Rural secondary school learners also helped criminals to steal and vandalize school property. They smoked dagga inside the school premises. Moreover, research findings indicate that rural secondary school teachers were not involved in school decision-making processes. School management teams were the only structure making school decisions. Growth opportunities for teachers were not fairly provided to them by their principals. Schools governing body chairpersons and principals were abusing the teacher promotion process since they were biased. They only promoted their friends and relatives and sometimes they were bribed by candidates. The latter findings contributed to teachers’ job dissatisfaction. Further findings indicate that there were teachers who were teaching subjects for which they were not qualified. Some heads of department were supervising subject streams that were outside of their specialization since the school post-provisioning norms (PPN) was small. Rural secondary school principals possessed inadequate grades 10-12 National Curriculum Statement expertise. Integrated Quality Management Systems was unable to develop teachers for effective grades 10-12 National Curriculum Statement implementation since it was not implemented accordingly in rural secondary schools. Clusters were effective strategies to develop teachers in rural schools although geographical isolation of school was their main challenge. The recommendations of this study are that RSSs must be fully supported by the KwaZulu Natal Department of Education. All roads to schools must be repaired in time. Decent teacher accommodation must be built inside schools with security guards to look after teachers’ safety and their property when they are away. Recreation venues/centres must be established in rural areas to relieve and address teachers’ stress and boredom. The KwaZulu Natal Department of Education must ensure that all schools have libraries, laboratories and computer classes. The Department of Education must also fully recognize postgraduate qualifications such as honours, master’s and doctoral degrees to retain highly qualified teachers in rural secondary schools. Teachers must be promoted on merit rather than on friendship or relationship

Improving continuing professional teacher development in the Foundation Phase: a subject advisor’s self-study.

Doctoral Degree. University of KwaZulu-Natal, Durban.I am a subject advisor in the Foundation Phase (Grades R–3) in the Department of Education in KwaZulu-Natal Province, South Africa. For this study, the focus was on my practice and learning as a subject advisor concerning the continuous professional teacher development (CPTD) programmes for teachers conducted by subject advisors. I looked into how I, as a subject advisor, could better support teachers. This study was located within the methodology of self-study of practice, where I used an arts-based self-study approach. Since I was looking at myself in practice, I was the main research participant. The other participants were three other subject advisors and 13 teachers from three different primary schools. Three research questions kept me focused in this study: What are the lived experiences and perspectives of subject advisors in relation to CPTD? What are the lived experiences and perspectives of teachers in relation to continuing professional development? And How might I use insights into subject advisors’ and teachers’ lived experiences and perspectives to improve my understanding and practice of CPTD? I used multiple methods to generate and analyse data, including audio recording of discussions, reflective journal writing, self-portrait drawing, and collage. Throughout my self-study journey, I learnt from a sociocultural theoretical perspective and social constructivism. A sociocultural perspective assisted me in understanding teachers’ and subject advisors’ learning backgrounds. In understanding social constructivism, I discovered that teachers and subject advisors learn better if they interact as they construct knowledge together. Self-study enabled me to change as I had to go deep and examine my own practice and reconstruct my thinking about how I have conducted CPTD. I gained confidence and valuable insights into my practice as I came to understand more about teachers’ and subject advisors’ experiences of CPTD. This thesis demonstrates the power of self-study to facilitate a process of learning, whereby improvement in practice can be achieved as we discern context-appropriate ways of bringing about changes in offering CPTD in challenging circumstances. The study also demonstrates how we can start to value teachers’ voices and input in planning and facilitating CPTD programmes that are more inclusive and participatory, and that address teachers’ genuine concerns

Quantifying non-exhaust emissions and the impact of hybrid and electric vehicles using combined measurement and modelling approaches

Road traffic is a significant emission source of urban particulate matter (PM). Due to the implementation of exhaust regulatory standards in the UK, PM emissions which arise from the wear of brakes, tyres and the road surface, together with the resuspension of road dust are now predicted to exceed tailpipe emissions. While a growing body of academic literature has developed in recent years, non-exhaust emissions (NEE) remain unregulated and largely understudied, and the impact of powertrain electrification on the vehicle fleet has not been quantified. Thus, the aim of this thesis is to improve our understanding of these important emission sources and to determine the impact of NEE on urban air pollution - both now, and in the future. A series of highly time-resolved atmospheric measurement campaigns has been undertaken at roadside and background locations to determine roadside traffic increments. These measurements provide a comprehensive dataset of traffic emissions in London, Birmingham and Manchester, incorporating locations with different vehicle mix and speed, during summer and winter periods. PM mass and elemental tracers have been used to estimate the contribution of NEE concentrations using a scaling factor approach. A novel CO2 dilution approach has been undertaken to determine average fleet emission factors (EFs), whilst the impact of electric vehicle regenerative braking has also been simulated. The results indicate that NEE concentrations and EFs are highly dependent upon meteorological conditions, traffic speed, traffic volume and vehicle class. Brake wear is the dominant source of road traffic PM emissions in congested environments, whilst for each emission source, heavy duty vehicles (HDVs) contribute an order of magnitude greater than light duty vehicles (LDVs). On the other hand, despite the predicted increase in mass, the regenerative braking simulations suggest that passenger vehicles under electric powertrains will reduce brake wear emissions by 65 – 95%. This reduction depends on the assessed drive cycle and vehicle class, highlighting the importance of driving style on future brake wear emissions. The EFs developed in this thesis have been combined with traffic forecasts to project total national emissions in the UK up to 2035 – and can be used to validate the national atmospheric emission inventory. To conclude, a number of recommendations have been made with respect to air quality measurement strategies and emission policies which are needed to further our understanding of NEE, and to reduce these traffic-related emissions. It is proposed that a multi-disciplinary study should be undertaken encompassing laboratory dynamometer testing, on-vehicle measurements and environmental atmospheric measurements.Open Acces
