India is fast becoming one of the largest economies worldwide, with expectations of becoming the second largest economy by 2050. The growth this country is demonstrating is accompanied by integration with other economies with active engagement in trade and investment in the world economy. Analysts and researchers strive to understand the possible effects of the rise of India on the global economy. The influence of India’s rise on Africa is an arguable topic. The Indo-Africa relationship has a strong political and socio-economic history. This relationship has undergone some changes since 1990 when India started a new approach that included internationalisation. In the modern economy the trade and investment from India to Africa have illustrated fast growth rates. It is claimed that India’s main interest in Africa is to gain access to Africa’s abundant resources with the intention of supporting its economic growth. This creates some concern on the nature of India’s involvement in Africa; whether or not it will increase the development and whether it will put pressure on Africa’s control of its resources. This study focuses on understanding the extent of Indian FDI in Africa and the factors that determine this involvement. Africa is known as the poorest continent worldwide; hence the development should be managed and controlled in order to sustain the growth. The flows of FDI to this continent can provide some advantages that include growth and development, while FDI can also prompt some disadvantages such as resource extraction. Profiling the determinants of Indian FDI in Africa provides an understanding of the influence India may have on Africa. Profiling the determinants of Indian FDI in Africa is done by means of a literature study that identifies the determinants that are applicable to African FDI. These determinants include natural resources, market size, political instability, macro-economic instability, weak policies, inflation, good governance, investment, GDP, growth, openness and oil production. Following the literature study an analysis is done on the trend of FDI worldwide and especially between India and Africa. The overall amount of FDI flows illustrates large increases globally and developed regions account for the majority of FDI flows. The trends of flows illustrate some changes that highlight the prominent role developing countries are starting to play. Africa is classified as a developing region that accounts for a fairly small amount of the total flows to the developing regions. It is noted that Africa’s share is steadily increasing and is expected to keep on rising. Indian FDI to Africa has demonstrated some staggering increases, while India claims to further increase its involvement. India’s FDI mainly flows to the resource sectors such as oil, coal and gas. India also states to expand its FDI involvement into African sectors such as the infrastructure, information technology, computer software, services and telecommunication. Identifying the specific determinants of Indian FDI in Africa is established by estimating models using the Structural Equation Method (SEMs). A combination of a factor analysis and regression analysis is estimated. The specific determinants that influence Indian FDI in Africa include government effectiveness, control of corruption, crude oil price, school enrolment and exports. The level or value of the investments is influenced by the government effectiveness and rule of law. This study concludes that India’s involvement in Africa is increasing. India demonstrates high levels of interest in Africa’s resources, but this is prone to expand across different sectors. / MCom (International Trade), North-West University, Potchefstroom Campus, 2013

The measurement of reliable and valid indicators of early child development is necessary for assessing phenomena and is useful in the monitoring of ongoing efforts to eradicate inequalities in the social determinants of health. There is an increasing awareness of the contextual, cultural, and developmental influences on constructs used in early child development (ECD) research. Using a measurement perspective, this dissertation examined the issue of measurement invariance and psychometric validity in early child development research. A construct violates the principle of invariance when two persons from different populations who are theoretically identical on the construct being measured have different scores on it. This dissertation consists of three journal-style manuscripts (published or under review) that were used as examples to address the importance of the issue of measurement invariance and psychometric validity in ECD research using data from two unique areas: autism and executive functioning. The three data sets were collected on pre-school children with parents and or teachers as informants and were chosen to represent different levels of data collection – clinical, community, and population. These data sets allowed for the examination of measurement invariance by type of informant, sex, and age of child. The results from the three studies illustrate the importance of assessing measurement invariance in ECD and whether or not the instruments examined can be used to assess sub-group differences with confidence. A lack of measurement invariance found for two of the studies, suggests that observed group differences in latent constructs could be attributed, in part, to measurement bias. More importantly, bias in the measurement of the constructs of severity of social impairment symptoms in autism, and executive functioning across groups could have an impact on services such as patient treatment. These biases could also influence public policy development, particularly when there may be an underlying need for a cross-group approach where belief systems may affect the meaning and structure of constructs. In summary, measurement invariance should be a prerequisite for making any meaningful comparisons across groups. A requirement of establishing measurement invariance should be included in the guidelines for comparative research studies as a necessary first step before an instrument is adopted for use.

Studiens syfte är att beskriva och statistiskt analysera relationen mellan styrelsens diversitet och hållbarhetsredovisningen med innovativa företag som medierande variabel. Då en hållbarhetsredovisning utgörs av flera kategorier fokuserar studien på de sociala aspekterna: produktansvar, arbetsförhållanden och arbetsvillkor, organisationens roll i samhället och mänskliga rättigheter. För att uppnå studiens syfte har en kvantitativ studie med deduktiv ansats utförts. Data har samlats in från GRIs (Global reporting initiative) databas där totalt202 multinationella företag som redovisat enligt GRIs senaste rekommendationer har hämtats och utgjort studiens urval. Data har analyserats med hjälp av en strukturell ekvationsmodell och en stiganalys. Resultatet indikerar att det finns positiva samband mellan diversitet i styrelsen, vad gäller utbildning och kön, och innovativa företag. Vidare pekar studien på samband mellan innovativa företag och redovisning av samtliga sociala aspekter utom produktansvar. De starkaste sambanden finns mellan redovisning av de olika sociala aspekterna i hållbarhetsredovisningen. Den medierande effekten av innovativa företag är lägre i studien än förväntat. / The purpose of this study is to describe and statistically analyse the relationship between the board diversity and CSD (corporate social disclosure) with innovative firms as mediating variable. As a CSD contains several categories this study focuses on the social aspects: product responsibility, labour practices and decent work, society and human rights. In order to achieve the study's purpose, a quantitative study with deductive approach has been carried out. Data have been collected from the GRI (Global reporting initiative) database in which atotal of 202 multinational firms, which have outlined their CSD according to the most recent recommendations made by GRI, have been derived and thereby formed the study's sample. Data have been analysed by means of a structural equation model and a path analysis. The result indicates that there is a positive relation between board diversity, in terms of education and gender, and innovative firms. Furthermore, the study indicates a relation between innovative firms and CSD regarding all social aspects except product responsibility. Thestrongest relation exists between the various social aspects in the CSD. The mediating effect of innovative firms is lower than expected in the study.

This dissertation addresses research questions related to defining a smart city and the associated activities. The general research question is explored in the dissertation via the conduct of three related studies. The finding from these three investigations are presented in the results section as 3 essays that collectively examine the smart city phenomena as it has emerged within the City. Essay 1 assesses building municipal open data capability. The study proposed an Opendata Roadmap Framework to enhance the organization's dynamic capability. The results provide a valuable practical framework to help cities develop open data capability. The results also provide a comparative study or benchmark for similar initiatives with other regional cities and within the nation. Essay 2 measures the residents' understanding and beliefs about smart cities. This portion of the research used a qualitative method that included interviewing residents and city officials to understand their definition of a smart city and what they believe makes a city smart. The interviews focused on understanding resident engagement because it is an important characteristic of a smart city. The gap between the city officials and residents understanding was examined. In addition, the interviews help identify essential factors associated with smart cities like trust in government, perceived security, perceived privacy, trust in technology, and perceived monetary value. Essay 3 examines the acceptance of smart city technologies and factors that affect the adoption of such technologies. This essay uses the insights from the other two essays to propose a smart city Unified Theory of Acceptance and Use of Technology (UTAUT) extension labelled Smart City UTAUT (SC-UTAUT). The new proposed model was tested using a survey method. The 1,786 valid responses were used to test the proposed structural equation model using Smart PLS. Results show a significant relationship between trust in technology, trust in government, perceived monetary value, effort expectancy, self-efficacy, and behavioral intention. The dissertation concludes with a summary of how the three essays make a cumulative contribution to the literature as well as providing practical guidance for becoming a smart city.

本研究旨在探討老年人寂寞及其相關因素模式。主要目的為：一、編擬老年人寂寞量表，以測量老年人寂寞。二、瞭解我國老年人的寂寞現況並比較不同背景變項之老年人在寂寞上的差異情形。三、建立人格特質（神經質與外向性）、自覺健康狀況、社會關係數量、社會供應（情緒共同感、價值肯定、社會共同感）與寂寞（情緒性寂寞與社會性寂寞）之間的結構方程模式，以瞭解變項之間的路徑關係。 為逹以上目的，本研究採用問卷調查法，以702位老年人為研究對象，施以「人格特質量表」、「社會關係量表」、「自覺健康狀況量表」，修訂之「社會供應量表」、自編之「老年人寂寞量表」等量表，並以描述性統計分析、t考驗、單因子變異數分析、結構方程模式進行統計分析。研究發現：1.老年人寂寞量表經因素分析，可區分為情緒性寂寞與社會性寂寞。2.我國老年人的寂寞程度為中度偏低，社會性寂寞顯著高於情緒性寂寞。3.不同年齡、性別、婚姻狀況、參與社團與居住狀況的老年人在寂寞上有顯著差異。4.去除解釋力低的自覺健康狀況，人格特質、社會關係數量、社會供應與寂寞所建構之結構方程模式的適配度獲得支持，可以有效解釋相關變項間的關聯性。 最後本研究根據研究結果進行討論，並對諮商實務及未來研究提出建議。 / The purpose of this study was to develop a 「Loneliness Scale for the Elderly」 and to explore loneliness and related factors in the elderly. Moreover, this study created the structural equation model of personality traits（neuroticis / extraversion）、quantity of social relationship、self-perceived health status、social provision（emotional togetherness / reassurance of worth / social togetherness）and loneliness（emotional loneliness / social loneliness）in the elderly, which served the purpose of illustrating the linear structural relationships among the relevant variables. The participants in this study were 702 elderly people in Taiwan. Research instruments included Personality Traits Scale、Quantity of Social Relationship Scale、Self-perceived Health Status Scale、Social Provision Scale, and Loneliness Scale for the Elderly. The collected data was analyzed by descriptive statistics, t-test, ANOVA, and structural equation model. The findings were as follows: 1. Two factors were extracted from the Loneliness Scale for the Elderly by factor analysis, they were emotional loneliness and social loneliness. 2. The level of loneliness among elderly was moderate and social loneliness is significantly higher than emotional loneliness. 3. There were significant differences in loneliness among different age groups, gender, marital status, group participations, and living arrangements. 4. The structural equation model of personality traits、quantity of social relationship、social provision and loneliness in the elderly could explain the relationship among main variables. Based on these findings, some suggestions were made for practice and future research.

This thesis draws on the framework of dynamic capability (DC) in an effort to make sense of how small and medium scale enterprises (SMEs) use mobile apps in Lagos, Nigeria. There exists significant knowledge regarding the application of the DC framework in large firms but its application in smaller organisations has scarcely been researched. The knowledge of how SMEs use mobile apps is important at this time because it could help these SMEs compete favourably, despite unpredictable environments. Based on pragmatic philosophy and a mixed-methods research approach, the research was conducted in two phases. The first phase of the research used qualitative methods to identify the absorptive, adaptive and innovative capabilities of SMEs in Lagos with a view to discover the extent to which mobile apps are used as enablers and/or drivers of these capabilities. The findings from 20 SMEs identified 15 DC constructs whose impact on SMEs could be enhanced using appropriated mobile apps. The SMEs manifest adaptive capabilities, mainly through using appropriated mobile apps. The SMEs manifest adaptive capabilities, mainly through customer feedback and referrals, and demonstrate absorptive capabilities through the repackaging and repricing of their goods and/or service offerings. The innovative capabilities of SMEs became evident through the imitation and adaptation of offerings. The second phase of this research surveyed 1 162 SMEs in Lagos in an effort to validate the identified constructs through quantitative methods. Descriptive statistics of survey responses affirm the use of mobile apps by SMEs and it also indicated the underutilisation of mobile apps as a DC enabler. Further analysis, using covariance-based structural equation modelling (SEM) techniques and confirmatory factor analysis (CFA), explored the fitness of a conceptual SME model. The model assembled seven latent variables namely: mobile app usage, adaptive capability, absorptive capability, innovative capability, opportunity sensing ability, opportunity shaping ability and opportunity seizing ability. Subsequently, 15 hypotheses aimed at understanding the relationships between the variables were developed. The findings from the quantitative analysis revealed that mobile app usage increases the adaptive, absorptive and innovative capabilities of SMEs. The results failed to establish a direct relationship between mobile app usage and opportunity sensing, shaping and seizing abilities. Furthermore, the use of the adaptive capability in taking advantage of opportunities could not be generalised in SMEs’ context. The research findings imply the existence of an untapped potential as far as the use of mobile apps by SMEs in Lagos is concerned. The findings suggest that SMEs in Lagos respond to opportunities by becoming innovative and they seldom exhibit innovation in order to create opportunities. Based on the heterogeneous nature of SMEs, it is difficult to suggest a clear-cut narrative as to how all SMEs should employ mobile apps to create and maximise opportunities. However, mobile apps could induce creativity when developed and applied to the contextual requirements of SMEs. The outcome of this research reflects a multidisciplined research experience. The study contributed to IS through the creation of a model for investigating mobile app usage by organisations from a DC perspective. The conceptual model designed in this study could be adapted to investigate the way in which mobile app usage influences organisations in other contexts. The study contributed to the area of Information Systems by revealing the application of the DC framework to SMEs in contrast to the usual practice of researching DC with large organisations in mind. This research work suggests implicit ways of enhancing SMEs which could aid policy makers. This study was limited in that it gathered data from SMEs in Lagos alone as Lagos represents the commercial centre of Nigeria. Considerations for future research include the comparison of DC of large and small organisations in Lagos to examine if similarities and/or contrasts exist. Furthermore, due to the evasive and heterogeneous nature of SMEs, it would be beneficial to delimit future research on SMEs along specific domains of interest. / Iqoqa Lolu cwaningo lususelwa ohlakeni lokuthiwa ngamandla aphilayo (dynamic capability [DC]) emzameni wokuba umuntu aqonde ukuthi amabhizinisi amancane namaphakathi (ama-SME) awasebenzisa kanjani ama-apps ahanjiswayo eLagos, eNigeria. Lolu lwazi lubalulekile ngoba lungasiza la mabhizinisi ukuba ancintisane namanye ngokunempumelelo, noma izimo akuzo wona zingaqondakali kahle. Ucwaningo lwenziwa ngezigaba ezimbili. Isigaba sokuqala sahlonza ama-DC ama-SMSE eLagos, ngenhloso yokuthola ukuthi ngabe ama-apps ahanjiswayo asetshenziswa kangakanani ukukhuthaza kanye/noma ukuqhubela phambili la mandla aphilayo. Okwatholakala kuma-SME angama-20 kwaba ukuhlonzwa kwezinhlelo zama-DC ithonya lazo kuma-SME elalingase liphakame ngokusebenzisa ama-apps ahanjiswayo afanele. Ama-SME afakazela ama-DC ikakhulu ngokushiwo ngamakhasimende nalabo abathintiwe, nokuba kubonakale ngokuba impahla ekhishwayo ipakishwe kabusha, ifakelwe intengo entsha, noma kube yimpahla engukulingisa eyokuqala noma ilungiswe ifane neyokuqala. Ibanga lesibili lalolu cwaningo lwahlola ama-SME ayi-1 162 eLagos ukuzama ukuqinisekisa ngezinga lezinhlaka ezihlonziweyo. Izimpendulo ezavezwa ucwaningo zakwesekela ukusetshenziswa ngama-SME kwama-apps ahanjiswayo, zakhomba nokuthi awasetshenziswa ngokugcwele ama-apps ahanjiswayo njengokunika i-DC amandla. Okunye ukuhlaziya kwakhombiisa ukuthi ukusebenzisa ama-apps ahanjiswayo kwakungasiza ama-SME ngokwandisa amathuba awo. Nokho phela ukusebenzisa amathuba avelayo kwakungeke kwenzeke yonke indawo kuma-SME. Okuvezwa ucwaningo kukhombisa ukuthi kukhona ukusizakala okukhulu okungakafinyelelwa kukho mayelana nokusetshenziswa ngama-SME kwama-apps ahanjiswayo eLagos. Ucwaningo luphonsa itshe esivivaneni enkundleni yezinhlelo zokusebenza ngezolwazi ngokwembula ukusetshenziswa kohlaka lwe-DC kuma-SME uma kuqhathaniswa ngokuphambene nalokhu, okungukucwaninga okwejwayelekile nge-DC ezinhlanganweni ezinkulu. Lolu cwaningo luveza izindlela ezingekho obala zokuthuthukisa ama-SME, okungaba usizo kulabo ababhekene nokusungula imigomo yezwe. / School of Computing / Ph. D. (Information Systems)

The purpose of study is to explore how the three quality might influence technology acceptance model, and what might strengthen user intention on e-government portal website. In addition, this study develops quality constructs as “formative-indicators”rather than reflective ones to correct the misuse of some literatures. The model is then tested using a sample of 1459 users from online survey and analyzed the data using structural equation modeling. The results show that(1) website service quality(WSQ) have the most effects on ease of use(EOU), and that (2)ease of use have the most effects on usefulness(PU). They also demonstrate that (3)attitude predit user intention the most. The significance illustrate logically the relation between formative-indicators of three quality and the constructs. Implications of this study for research and practice are presented.

The purpose of this study was to identify the relevant factors to develop a framework for optimising public participation to improve service delivery in a metropolitan municipality in South Africa. This approach was undertaken with a view to identify the gaps created through the expectations generated among citizens by the national government and the weaknesses in the capacity of the local government to deliver through its supply chain processes, and hence develop strategies to close the existing gaps as much as possible. There were four samples in the study namely: citizens, managers, businesses and ward committee members (WCM). The data that were collected for citizens were conducted at each Customer Care Centres (CCC). For the other three sets of respondents, it was conducted through email. The research approach was quantitative. Factor analysis was applied in this research study in order to identify significant factors that drive public participation in service delivery by local government. Findings of this study showed that there are two major perceptions of the respondents perceived to affect the optimisation of effective service delivery: 1) the facilitating factor and 2) the impeding factor. This was assisted by Structural Equation Modelling (SEM) where a model was designed which resulted in the development of the public participation framework for effective municipal service delivery. These findings will inform the management of local governments to prioritise inclusion of all citizens by optimising their participation for effective service delivery. Areas where participation in local government was lacking were identified and this study presents well-informed strategies for local governments and for their possible implementation. / Business Management / D.B.L.
