Thesis (MDF)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: The Nigerian economy has suffered huge infrastructure deficits since her independence in 1960, thereby limiting economic growth potential of the country considerably. This research conducted a Granger causality test between Real Gross Domestic Product, infrastructure investment and productivity across manufacturing, agriculture and industrial sectors in Nigeria for the period 1981 – 2012 using multivariate vector error correction model. The co integration test shows that there is a long run relationship between infrastructure investment and economic growth at both at 1 percent and 5 percent levels of significance. Further, the granger causality test indicated a one way causal relationship between infrastructure investments and economic growth in Nigeria running from infrastructure investment to Real Gross Domestic Product growth. We equally established a one way causality relationship between agriculture sector productivity and gross domestic product growth, a one way causal relationship between manufacturing sector productivity and Real Gross Domestic Product growth and a very significant one way causal relationship that runs from infrastructural investment to agriculture sector productivity, all running from the former to the latter. The economic implication of this is that the existing level of infrastructure investment in Nigeria is a significant contributing factor to growth in the level of rea gross domestic product. However, despite the sustained real gross domestic product growth, the Nigerian government has been unable to translate this growth to physical infrastructure development. We conclude that in order to achieve the double digit economic growth needed for a comprehensive economic transformation of Nigeria, the Nigerian government needs to accord greater priority to infrastructure development, particularly in the agricultural and manufacturing sectors.

This research paper is broken up into three sections, namely an evaluation report, a literature review and research methodology. The evaluation report section is the assessment of the current state of change readiness within the Eskom Contact Centre’s based upon what the literature on change readiness prescribes. The timing of the change readiness assessment is just prior to significant organisational change. The organisational change that was about to be initiated by the organisation was initiated from the boardroom of the most senior echelons of the organisation, and was directed in a top down approach, being a strategic organisational change. The change is deemed to be critical to the organisation being able to meet its long term strategic and sustainability objectives. A critical examination of the literature explored the meaning of change readiness, the importance of it and explained the consequences for organisations that commit to transformational agendas without being ready. Key concepts such as such resistance to change and organisational inertia are described and differentiated from change readiness. The ADKAR change model and its change readiness assessment instrument were used due to the organisations preference for the model. The ADKAR model formed the framework for the analyses of the data, the discussion of the results and the recommendations to the organisation. The research conducted was quantitative in nature; a questionnaire was distributed to the employees of the seven Eskom Contact centre sites around the country through an email. A slightly modified version of the ADKAR change readiness questionnaire was sent via email with an on-line questionnaire link on it; and questions on individual readiness for change were used to assess the level of readiness of the employees. Most of the descriptive and inferential statistics were analysed with the use of Excel (version, 2010), with Factor Analysis being done in Statistica. The results of the research showed that: [iii] - The factors as proposed by the ADKAR change readiness assessment questionnaire (i.e. Awareness, Desire, Knowledge, Ability and Reinforcement) are not different enough to be considered as independent factors for this data set. Based on factor analysis, the factors were subsequently amended from five to three, namely Readiness, Opportunity Realisation and Uncertainty. - The Contact Centre employees were somewhat ready for change. - The Contact Centres needed to focus on all amended ADKAR factors in order to improve the readiness of the department. - The readiness levels in response to the roll out were more or less uniform. The study shows that given Eskom’s preference for the ADKAR model, future research within Eskom should therefore be conducted more circumspectly with respect to ascertaining the validity of the ADKAR factors. The study also makes mention that future work and/or research will need to be conducted, specifically on the readiness of the organisation itself, in order to improve the probability of transformational success. The ADKAR assessment is a people focused assessment and therefore focuses only on the readiness of the individual. Factors such as the adequacy of the current state of resources within the organisation, which incorporate aspects such as infrastructure, technology and staffing, will also need to be assessed to make a more holistic statement of change readiness. A concise review of the literature is incorporated into the Evaluation Report of Section 1 to underpin the study. In Section 2 a more extensive review of the literature is presented. Similarly, the design of the research is discussed in more detail in Section 3 to both describe and justify the appropriateness of the research methodology, and to give a detailed account of the way in which the research was carried out.

Exchange rates are believed to be one of the major driving forces behind sustainable macroeconomic growth and it is therefore important to ensure that they are at an appropriate level. Exchange rate misalignment is a situation where the actual exchange rate differs significantly from its equilibrium value, resulting in either an overvalued or an undervalued currency. The problem with an undervalued currency is that it will increase the domestic price of tradable goods whereas an overvalued currency will cause a fall in the domestic prices of the tradable goods. Persistent exchange rate misalignment is thus expected to result in severe macroeconomic instability. The aim of this study is to estimate the equilibrium real exchange rate for both Ghana and Nigeria. After so doing, the equilibrium real exchange rate is compared to the actual real exchange rate, in order to assess the extent of real exchange rate misalignment in both countries, if any such exists. In order test the applicability of the equilibrium exchange rate models, the study draws from the simple monetary model as well as the Edwards (1989) and Montiel (1999) models. These models postulate that the variables which determine the real exchange rate are the terms of trade, trade restrictions, domestic interest rates, foreign aid inflow, income, money supply, world inflation, government consumption expenditure, world interest rates, capital controls and technological progress. Due to data limitations in Ghana and in Nigeria, not all the variables are utilised in the study. The study uses the Johansen (1995) model as well as the Vector Error Correction Model (VECM) to estimate the long- and the short-run relationships between the above-mentioned determinants and the real exchange rate. Thereafter the study employs the Hodrick-Prescott filter to estimate the permanent equilibrium exchange rate. The study estimates a real exchange rate model each for Ghana and Nigeria. Both the exchange rate models for Ghana and Nigeria provide evidence of exchange rate misalignment. The model for Ghana shows that from the first quarter of 1980 to the last quarter of 1983 the real exchange rate was overvalued; thereafter the exchange rate moved close to its equilibrium value and was generally undervalued with few and short-lived episodes of overvaluation. In regard to real exchange rate misalignment in Nigeria prior to the Structural Adjustment Program in 1986 there were episodes of undervaluation from the first quarter of 1980 to the first quarter of 1984 and overvaluation from the second quarter of 1984 to the third quarter of 1986; thereafter the exchange rate was generally and marginally undervalued.

The question of ethnicity has been one of the most topical subjects of study by social scientists. The controversies around this phenomenon seem to have been heated up by the high visibility of mobilized and politicized ethnic groups in most multi-ethnic states. Therefore, the extent to which ethnic nationalities are able to effectively manage the interplay of ethnic differences determines to what extent a multi-ethnic nation develops without crisis. Historically Nigeria has come a long way from multi-ethnic entity with political differences and background to the amalgamation of 1914 till the present structure of thirty-six states. Ethnicity, no doubt has contributed immensely to ethnic conflicts in Nigeria because of long standing revulsion or resentments towards ethnic groups different from one’s own or fear of domination which can as well lead ethnic groups to resort to violence as a means to protect and preserve the existing ethnic groups. Significantly ethnicity in Nigeria, is a product inequality among the various ethnic groups orchestrated by a long period of colonialism; a period which witnessed the ascendancy of three major ethnic groups to the socio-political domination of other ethnic groups and a period when the three major ethnic groups were used as a pedestal for the distribution of socio-political goods, resulting in the inability of other ethnic groups to access these socio-political goods. This situation has continued to impact negatively on the forces of national integration and cohesion in ethnically divided Nigeria. Considering the relationship between ethnicity and development; socio-political exclusion is not only ethically dangerous to development but also economically unproductive. It deprives groups and individuals of the opportunity for the necessary development that can be beneficial to the society. Thus, it is important to develop an integrative socio-political frame-work that explicitly recognizes the participatory role of every ethnic group in governance. Hence, there is a need for the adoption of inclusive governance to manage ethnicity in Nigeria. Notwithstanding, ethnic conflict still persists and an attempt will be made in this study to identify the reasons. Central to socio-political sustainability in Nigeria is a system that should recognize that differences are important to development and encompass notions of equality. Such a system should acknowledge the socio-political and economic power of every ethnic group and promote a system devoid of ethnocentric and exclusionary socio-political and economic policies.

The aim of this study is to examine conflict and how it impinges on development. Conflict is an inevitable element of human existence since creation and has always affected human activities and endeavors in several ways. Understanding the dimensions of human conflict therefore provides blueprints on how to manage and resolve conflicts. This makes this study timely. In this research, some relevant related to conflict management approaches were examined. The research adopted a case study approach using the Jos Plateau conflict in the Plateau State of the Federal Republic of Nigeria. Data was collected and analyzed using a mixed research methods approach. The findings show several causes of this conflict among which are differences in religious beliefs among the people of the area, socio-economic causes, political tensions and land disputes. The consequences of the conflict identified are: it retards development in the area, creates fear and feelings of insecurity, destruction of property and loss of human lives. This study also examined how the conflict impinges on people-cantered development. In terms of how the conflict can be mitigated, respondents think education, creation of employment opportunities, the administration of justice and the practice of tolerance values is going to promote a spirit of coexistence and eventually result in a more peaceful and stable environment.

China’s economic expansion in recent years is one of the most important geopolitical developments of the 21st century (Mockli, 2007). More interestingly, Africa relations with China continue to be of keen concern to many, precisely because these two countries have been humiliated severely during the years of colonialism. This study examines, to the extent possible, Chinese changing foreign policy and resource diplomacy towards Africa, using Nigeria as a case study specifically looking at socio–economic issues. The study uses the Hegemonic Stability Theory as a framework of analysis. While the method of data collection is premised on existing qualitative and quantitative analysis on Africa–China relations, faceto- face interviews and one telephonic interview with an expert on Africa–China relations were conducted as a method of gathering new data. The present study, finds that China’s economic expansion can be detrimental to Africa in many ways. For instance, China continues to export to Africa cheap manufactured goods, while extracting raw materials to fuel its own industrialization. This situation works against intra–Africa trade, which could potentially address the socio–economic issues facing the continent. However, to maintain its resource supply and stable market, China’s foreign policy of ‘non–interference’ has changed significantly, particularly towards Africa. For example, China recently opened its first military base in Africa. This study argues that, because of the above mentioned arguments, the repercussions of the Africa–China relations could be dangerous for Africa since the continent is not really benefiting from these dealings. Furthermore, this study notes that China is contributing negatively towards the socio–economic development of Nigeria, despite the fact that it provides Nigeria with aid and loans, primarily for infrastructure projects. / Development Studies / M.A. (Development Studies)

This thesis contributes to the ongoing global discourse in ICT4D on ICT and its effect on socio-economic development in both theory and practice. The thesis comprises five studies presented logically from chapters 5 to 9. The thesis employs Mixed Methods research methodology within the Critical Realist epistemological perspective in Information Systems Research. Studies 1-4 employ different quantitative research and analytical methods while study 5 employs a qualitative research and analytical method. Study 1 proposes and operationalizes a predictive analytics framework in Learning Analytics by using a case study of the Computer Science Department of the University of Jos, Nigeria. Multiple Linear Regression was used with the aid of the Statistical Package for Social Sciences (SPSS) analysis tool. Statistical Hypothesis testing was then used to validate the model with a 5% level of significance. Results show how predictive learning analytics can be successfully operationalized and used for predicting students’ academic performances. In Study 2 the relative efficiency of ICT infrastructure utilization with respect to the educational component of the Human Development Index (HDI) is investigated. A Novel conceptual model is proposed and the Data Envelopment Analysis (DEA) methodology is used to measure the relative efficiency of the components of ICT infrastructure (Inputs) and the components of education (Outputs). Ordinary Least Squares (OLS) Regression Analysis is used to determine the effect of ICT infrastructure on Educational Attainment/Adult Literacy Rates. Results show a strong positive effect of ICT infrastructure on educational attainment and adult literacy rates, a strong correlation between this infrastructure and literacy rates as well as provide a theoretical support for the argument of increasing ICT infrastructure to provide an increase in human development especially within the educational context. In Study 3 the relative efficiency and productivity of ICT Infrastructure Utilization in Education are examined. The research employs the Data Envelopment Analysis (DEA) and Malmquist Index (MI), well established non-parametric data analysis methodologies, applied to archival data on International countries divided into Arab States, Europe, Sub-Saharan Africa and World regions. Ordinary Least Squares (OLS) Regression analysis is applied to determine the effect of ICT infrastructure on Adult Literacy Rates. Findings show a relatively efficient utilization and steady increase in productivity for the regions but with only Europe and the Arab States currently operating in a state of positive growth in productivity. A strong positive effect of ICT infrastructure on Adult Literacy Rates is also observed. Study 4 investigates the efficiency and productivity of ICT utilization in public value creation with respect to Adult Literacy Rates. The research employs Data Envelopment Analysis (DEA) and Malmquist Index (MI), well established non-parametric data analysis methodologies, applied to archival data on International countries divided into Arab States, Europe, Sub-Saharan Africa and World regions. Findings show a relatively efficient utilization of ICT in public value creation but an average decline in productivity levels. Finally, in Study 5 a Critical Discourse Analysis (CDA) on the UNDP Human Development Research Reports from 2010-2016 is carried out to determine whether or not any public value is created or derived from the policy directions being put forward and their subsequent implementations. The CDA is operationalized by Habermas’ Theory of Communicative Action (TCA). Findings show that Public Value is indeed being created and at the core of the policy directions being called for in these reports. / School of Computing / Ph.D. (Information Systems)
