  • Description: E-government has been adopted as one of the cornerstones of the government‘s strategy for making services accessible to its citizens. The aim of this broadband adoption is to provide high quality public sector services via digital channels to improve cost-efficiency and generate benefits to municipality employees and citizen. A major challenge that municipalities face is the lack of public participation which restricts levels of communication between governments and municipalities and the citizen where public misses out on information and services available online, which results in further inequality. This has a devastating impact on service delivery because participatory democracy would be non-existent. Limited IT infrastructure, resistance to change, cultural barriers and exposure of malpractice are main themes related to IT usage or facilitating IT access for the wider public. Furthermore, lack of meaningful participation and freedom of association emerged as themes related to governance effectiveness. A mixed approach within a case study was considered, and data was collected through an online questionnaire and review of current literature. The study collected primary data by conducting web based questionnaires comprising sixty respondent’s citizens and fifteen municipal employees, including Information and Communication Technology (ICT) employees and broadband task team members. Statistical Package for the Social Science (SPSS) to analyse data from questionnaires. The selected BCMM employees of the population were known to have the relevant knowledge, time and experience to participate. Responses to each question developed the framework further based on the findings. Respondents were selected based on their appropriate knowledge and experience of the problem domain. Six experts were selected for final evaluation of the research findings. Firstly, the findings provided on barriers impact on the adoption of e-government. Secondly, on the techniques available to ensure access to e-government within BCMM. Thirdly, on the availability of technologies currently in the Buffalo City Metropolitan Municipality. Finally, on the elements of a Buffalo City Metropolitan Municipality broadband adoption strategy. This study evaluates barriers of e-government adoption, assessing strategies and techniques for accessing e-government services, examines current technologies to support e-government service within municipalities and analyses elements of Buffalo City Metropolitan Municipality broadband adoption strategy. A broadband adoption model was proposed based on empirical findings. Key adoption factors include adoption benefits and drivers, concerns and barriers and adoption interventions. These factors provide an essential foundation for the development of the proposed broadband adoption framework. The contribution of this study is a framework based on the Unified Theory of Acceptance and Use of Technology (UTAUT) and Technology Organisation Environment (TOE) framework to determine factors that influence or restrict a citizen’s intention to use and adopt technology, specifically broadband, in e-government services as a tool for citizen engagement. The proposed framework aims to overcome barriers to broadband adoption 4 Final Submission of Thesis, Dissertation or Research Report/Project, Conference or Exam Paper in municipalities, specifically Buffalo City Metropolitan Municipality (BCMM) to enable citizens’ access to e-government services.

  • Description: E-government has emerged as an effective means of delivering much-needed online services to the citizens, businesses and other government institutions. This emanates from the advancement of Information and Communication Technology (ICT), the internet and the emerging technologies associated with the Fourth Industrial Revolution (4IR). E-government has essentially transformed the culture, structure and the way of doing business by public institutions in providing government services. In the past, e-government has been popular in developed countries but recently many developing countries are starting to appreciate the need to implement the initiative. However, the implementation of e-government has various challenges that have been identified through research and include technological, organisational and environmental aspects. Therefore, the researcher was motivated to study e-government to improve the delivery of services to citizens in South Africa. The objective of the research was to develop a framework for the implementation of egovernment as a service delivery mechanism in South Africa. The research process led to the identification of challenges that impact the implementation of e-government by applying an underlying Information Systems (IS) theoretical model, namely the Technology-OrganisationEnvironment (TOE) framework. The review of literature allowed the researcher to construct a conceptual theoretical framework which was then applied to the case study in order to understand the factors affecting the implementation of e-government in South Africa. Qualitative research data was collected using Thusong Service Centres in the Eastern Cape as a case study. Thusong Service Centres are government service centres based in rural communities which are used for the provision of online government services to these communities. The empirical data was collected using 22 respondents from five organisational and user perspectives: (1) State Information Technology Agency (SITA) as an agency of government responsible for ICT in South Africa, (2) the Senior ICT Managers from various National, Provincial and Local government entities, (3) Thusong Service Centre Managers, (4) Thusong Service Centre End-Users and (5) Expert Reviews. Documents that included the National e-Government Strategy, e-Government Policy, National Broadband Policy, ICT Policy White Paper were also consulted as secondary data. The conceptual theoretical framework was then revised based on the empirical evidence using the interpretive exploratory approach and triangulated data. The consolidated data from both the literature review and empirical evidence assisted in closing the gap between e-government implementation theory and practice. A detailed e-government implementation framework was then developed with the critical factors that impact the successful implementation of e- ii | P a g e government. E-government subject experts were also given the mandate to review the interview questions and the framework. The use of this framework was then explained in terms of how it can assist government decision-makers in South Africa for the effective and efficient delivery of services to the citizens. The research study has contributed to the e-government body of knowledge through the identified factors utilising the TOE framework at an organisational level for developing countries like South Africa.

  • Description: The Vaalbank and Lady Frere areas belong to the Elliot, Molteno and Burgersdorp Formations, that are part of the sedimentary succession of the Beaufort Group in the Karoo Basin of South Africa. There is Quaternary alluvium covering the mudstone, sandstone and shale rocks of the Beaufort Group. Dolerite and gabbro sills of the Karoo age have intruded the whole area. A number of investigations were carried out for the study namely field observations, petrographic, X-ray diffraction, airborne gamma-ray spectrometry, aeromagnetic and gravity analyses. Twenty four rock samples were collected in the field from fresh outcrops of the Karoo dolerites, Burgersdorp and Molteno formations. The measured densities and porosities show that the Karoo dolerite suite has the highest average dry density of 2.771 g/cm3 and the lowest average porosity of 3%. The Burgersdorp Formation has an intermediate average density of 2.458 g/cm3 and an intermediate average porosity of 5.4%. The Molteno Formation has the lowest average density of 2.190 g/cm3 and the highest average porosity of 14.5%. Petrographic and geochemical investigations were carried on 19 rocks samples collected in the field to determine the mineralogy character using microscopic and XRD analyses. Both petrographic and X-ray diffraction analyses revealed that the sandstones of the study area are composed of quartz as their primary mineral and feldspars as the secondary mineral. The dolerite consists of euhedral structured minerals such as magnetite, pyroxene, plagioclase and amphibole. The gamma ray maps show high spectrometric values are associated with the Burgersdorp Formation, alluvium cover and dolerite dykes. The low spectrometric values are associated with dolerite sills and ring complexes. The boundaries of the sill/ring complexes are clearly delineated by the K/U ratio and ternary maps. The magnetic maps show ring like patterns of magnetic high anomalies that are due to the sills/ring complexes whilst the numerous, narrow, linear magnetic highs are due to faults and dolerite dyke swarms. The majority of the dykes trend in a NW-SE direction and a few dykes are in a NE-SE direction. The magnetic power spectrum indicates four depths of the magnetic sources at average depths of 0.13 km, 1.60 km, 2.83 km and 12.40 km. The magnetic depth iii slices maps show that both the circular/ring like and linear anomalies extend from shallow to deeper depth of 12.4 km. The gravity map is dominated by a long wavelength gravity anomaly that increases from about -120 mGals in the northwestern corner of the study area to -110 mGals in the southeastern corner of the study area. Results from 2½D gravity modelling show that this long wavelength anomaly is due to a horizontal Moho at a depth of 47 km in the study area, which shallows outside the study area near the coast. Superimposed on it are short wavelength gravity anomalies due to low density sediments and high density dolerite intrusions. The simple 2½D models generated from five profiles traversing the study area reveal that the sediments of the Karoo Supergroup extend from the surface down to a depth 5 km below sea level attaining a maximum thickness of about 6½ km. These sediments are dykes, sills and ring complexes. The dykes and sills/ring complexes identified from gamma ray spectrometry, magnetic and gravity data results are likely to be associated with fractures, joints, cracks and fissures in the host rocks, which form preferential pathways for groundwater transmission. Hence, they could be suitable targets for groundwater.

  • Description: This study sought to investigate the access to information about social grants by the elderly population of Balfour village in Raymond Mhlaba Local Municipality in SA’s Eastern Cape Province. A study on access to information is quite relevant in the knowledge-based economies. People act when they have information and similarly elderly people require information in order to access their grants. This study is quite relevant in the Library and Information Science field. The targeted population for the study were the elderly people of the Balfour village. The qualitative research approach was used in this study. The researcher selected a sample for the study using snowballsampling procedure. Both in-depth interviews and questionnaires were employed as methods of gathering data and thematic analysis of data was used. Results showed that there is a lack of information dissemination and access to information about social grants for elderly people living in Balfour. The study found out that elderly people in Balfour complained that, in most cases, they were not sure about the documents they were supposed to bring with them when they visited the South African Social Security Agency offices. This indicates the need for SASSA to train their staff members to be customer orientated and encourage staff to empower themselves with formal educational qualifications. In addition, the distance to and from SASSA offices is of great concern because elderly people spend significant amounts of money for travelling these distances. Therefore, there must be an office that is situated in a favourable distance to the elderly so that they do not struggle when they want to reach SASSA offices. Another option would be to avail a mobile office that may serve the area two or three times a week.

  • Description: Accessibility to relevant, accurate and timely information remains vital in farming. For farmers to improve their productivity they depend on access to pertinent agricultural information. Such information updated them about new agricultural technologies, climate change, new cultivars, access to market and access to financial assistance. These types of information help farmers in decision making regarding their farming. Agricultural extension officers remain a reliable source where farmers could obtain relevant agricultural information. Community libraries are also channels that could be used by agricultural extension officers to complement their work of providing farmers with information. Thus, the study sought to assess linkage between these two institutions to provide farmers with information. A positivism paradigm with quantitative research approach were adopted in the study. Smallholder farmers (169), agricultural extension officers (5) and librarians (15) were the unit of analysis. A semi-structured questionnaire was used for data collection and SPSS software for analysis. Findings revealed that, agricultural extension officers mostly utilise interpersonal channels that include demonstrations, group meetings and face-to-face interaction to provide farmers with information. Community libraries were found to be non-utilised by extension services and also by farmers. Farmers were of the perception that libraries are meant for educated people. It was also discovered that community libraries have information on agriculture that only targets learners who are taking agriculture in school as a subject. There was no existing linkage between agricultural extension services and community libraries working together to provide farmers with pertinent agricultural information that can help them improve productivity

  • Description: The use of social networks has grown so much that adolescents have become active members of various social networks such as Twitter, Facebook, and Instagram, etc. The gradual change in how people choose to communicate, socialize and share ideas today has influenced adolescents to an extent that they find themselves wanting to engage more on social networks than they really should due to peer pressure. Whenever a person joins social networks or browses the Internet, they by default are exposed and become vulnerable to many cyber threats. Cyber threats are driven by users that have negative intentions on the Internet or social networks. Adolescents are no exception to these cyber threats. The findings of this research reveal that threats such as cyberbullying, harassment, and online predators to name a few are often designed to abuse and affect adolescents). Therefore, this research aims to prevent such threats from prevailing by empowering parents to be aware of the threats that affect their adolescents in an online environment, which typically includes social networks. To achieve this, this research starts by investigating the cyber threats that affect adolescents and then explores ways that can be used to empower parents. A framework is developed to handle this. The framework includes strategies that parents can adopt and ways in which safety on social networks can be increased, as well as guidelines that can be followed in order to prevent cyber threats. The framework also aims to enhance a parent-child relationship that can help in preventing social network threats. Lastly, the framework is implemented as a knowledgesharing website that can be used by parents to receive and give an insight into social network threats that influence adolescents on social networks.

  • Description: Pentecostal churches in Nigeria are leveraging traditional and new media technologies such as cable or digital satellite television, to broadcast services and programmes to their regular and a growing community of virtual worshippers. Critics of this type of religious outreach now known as televangelism have challenged its predominant, if not exclusive focus on miracle and prosperity message. Using the mixed-method research design involving focus group discussions, key informant interviews and a survey of 255 respondents, this study sought to ascertain Lagos audiences‘ perceptions of Pentecostal Television programmes on two satellite stations, Start Times and DSTV. The findings revealed that audience members perceive Pentecostal churches programme as primarily focused on converting the audience members to the Christian faith. The result revealed that miracle sessions are a common feature of televangelism. Respondents see the miracles as manipulations largely intended to woo and often, hoodwink audience members. The findings revealed that although some of the Pentecostal churches‘ programmes dwell more on the word of God compared to the mainline churches, the programmes and teachings, however, often tended to promote the leadership of the church and not the gospel of Christ. Generally, the study indicates the majority of the audience members are aware of and identify with the atrocities the Pentecostal Churches are accused of perpetrating through their TV programmes. The findings revealed poor awareness and knowledge about the role of the Nigeria Broadcasting Corporation (NBC). The results suggest participants do not believe the NBC is living up to its responsibilities. The findings of this study highlight the need for the NBC, the Christian Association of Nigeria (CAN) and Pentecostal Fellowship of Nigeria (PFN) to work together in formulating new regulations for controlling religious broadcast on television, Pentecostal TV broadcasts, in particular. This is the only way to safeguard vulnerable members of the audience from being manipulated and brainwashed.

  • Description: The aim of this study was to characterize the protease enzyme (s) from red algae. An in silico analysis of red algae genomes was used to identify gene coding for protease. Protease sequences identified from these genomes were examined for conserved domains, active site and structures. The domain search revealed that the identified sequences were from the five classes of protease enzymes. For function inference, the red algae sequences were aligned to identify the catalytic sites, and the tertiary structures were predicted using homology modelling. An in silico analysis provides an indication of the class and potential functions of the enzymes. However, it cannot predict whether the gene is constitutively expressed in the red algae or under which conditions it may be induced, and it cannot determine the kinetic efficiency of an enzyme against various substrate, or the optimum conditions for the protein activity. Attempts to clone and recombinantly express selected red algae proteases, proved unsuccessful, as the available genomes where from red algae species found mainly in Asia, and the designed primers, therefore, did not amplify a corresponding PCR product from the red algae harvested in South Africa. Crude extracts of red algae collected from Kenton-on-Sea, along the East Coast of South Africa, were screened for protease activity using Benzoyl-Arginine-pNitroAnilide (BApNA) as substrate. The proteases detected in the crude extract were purified using ammonium sulphate precipitation and HiPrep DEAE FF 16/10; CM FF 16/10, and HiPrep Q FF 16/10 columns for ion-exchange chromatography. The HiPrep Q FF 16/10 column yielded active protein, which revealed two bands of 11kDa and 17kDa on SDS-PAGE. It was assumed that these bands represented two subunits of the purified protease. Kinetic characterisation of the purified protease revealed a pH optimum of 9, using BApNA as substrate, a temperature optimum at 60ºC, and sensitivity to temperature when stored above 4ºC. The protease activity was inhibited by Ferric chloride (32%), induced by calcium chloride (156%), no inhibition by magnesium chloride (97%) and slight inhibition by potassium chloride (77%) and manganese chloride (70%). Phenylmethylsulfonyl fluoride (PMSF), a serine protease inhibitor, almost totally inhibited the protease activity, indicating that the protease from red algae was most likely a serine protease. The Km and kcat values were 1.96 µM, and 0.364 s -1 , respectively using BApNA as the substrate. This study revealed that the red algae genome contains numerous genes that encode for proteases from almost all the classes of proteases. A serine protease from the red algae Gelidium pristoides was partially purified and kinetically characterised, confirming that red algae found along the Eastern Coast of South Africa contain genes that express active proteases that may be of medical or industrial interest. Further studies, however, are required to recombinantly express, purify and characterise the numerous proteases encoded by the genes identified in the in silico analysis of this study.

  • Description: As a standard, photovoltaic (PV) modules are rated by the use of standard test conditions (STC). Such details entail current and voltage (I-V) measurements for modules under an irradiance of 1000 W/m2 an air mass ration of 1.5 global spectrum and 25˚C cell temperature. Outdoor weather conditions continuously vary with time and from one location to the other. This further offset the expected operational power outputs as outdoor conditions are generally characterized by high cell temperatures. The technology one uses will also complicate the power output prediction since different module technologies respond to these outdoor conditions differently. I-V tracers are able to measure the full I-V curve of the module thus can give the operational PV parameters at any given time. However, these tracers are sold at exorbitant prices and they require skilled personnel in order to operate them. Most if not all tracers require isolation of the module under test thereby disrupting the power production function of the module._________________________________________________________________________________________________________________________________________ In this study a method to obtain photovoltaic (PV) parameters using the maximum power point tracking (MPPT) data is presented and tested under natural outdoor conditions. The method features a customized data acquisition system (DAS) designed for the measurement and storage of meteorological and MPPT data. The DAS is capable of extracting parameters from any combination of modules with an open circuit voltage 〖(V〗_oc) less than or equal to 120 Volts and a short circuit current 〖(I〗_sc) of 100 Amps. The system used is capable of extracting MPPT data using a reliable, improved storage and a programmable data logger. In order to match the sampling operational speeds of internal charge controller switches a computer interfaced Peripheral Component Interconnect (PCI) card was also used. Data collection and characterization of the MPPT data was done in such a way that the power generation process remained uninterrupted throughout the whole process. The regression nonlinear least squares method was used to fit MPPT crests and obtain the knee part of the I-V curve. This was then extrapolated to obtain the full I-V curve, which then produces the operational PV parameters. The resultant parameters from the characterization process were logged and accessible at any time. The end result was a method that can be incorporated within a charge controller for quick, hands-free PV parameter extraction, using only the MPPT scanned data.

  • Description: The drive of this research project was to discover factors contributing to the poor academic performance of Grade 12 learners at two selected schools in the Butterworth Education District, Eastern Cape province South Africa. The participants were Grade 12 learners, Grade 12 teachers and parents of Grade 12 learners in both schools. Both schools are located in rural areas of Mnquma municipality under the Butterworth education district. The study used both qualitative and quantitative research methods. The motivation behind using triangulation was to decrease or offset the deficiency of a specific methodology and for deeper understanding of the discoveries of the study. Use of triangulation in this study was aimed at expanding the legitimacy, dependability and generalizability of the results of the study. The findings of the study revealed that the most determining factor that contributes to the poor academic performance of Grade 12 learners in the Butterworth Education District is the unavailability and inadequacy of instructional resources. This is the most critical school resource which the parents cannot afford to buy for their children. Both teachers and Grade 12 learners indicated that they do not have a school library or a community library. The majority of learners also indicated that they do not have enough textbooks in all subjects and their parents concurred that their children end up sharing textbooks with their peers. Furthermore, the three groups of participants agreed that learners do not have access to computers, and the school does not have a science lab for Grade 12 learners doing science. The core argument of this study is that a poor socio-economic background is a primary contributor to low academic performance of Grade 12 learners at the Butterworth Education District. The findings of this study support this thesis as they indicate that instructional resources are inadequate, a school or community library is vii non-existent, and there is not enough textbooks at the selected schools. With parents from low socio-economic background, the Butterworth community is also not in a position to supplement these insufficient instructional resources. This study utilized the cultural reproduction theory of Bourdieu (1977) to explore a system of education in industrialized communities and the way it works to illuminate class differences in academic performance and achievement of Grade 12 learners. The study made recommendations that should be put in place to improve the academic performance of Grade 12 learners in the Butterworth Education District. The most important of these recommendations is that government officials should provide educational resources (teaching and learning resources). Furthermore, the researcher suggest that for further research, it would be interesting to find out about learners that perform well, regardless of identified factors that cause other learners to perform poorly to help them improve their academic performance.

  • Description: Background: In 2014, South African Department of Health (SADOH) initiated use of Implanon NXT, a type of implant in addition to long-acting reversible contraceptives available in the country to expand contraceptives options for women of reproductive age. After its introduction, there were reports on early removals and frequent side effects. It is therefore vital to identify how successful the implementation of this method was in particular in East London area. Objectives: The purpose of this study was to evaluate how successful the implementation of Implanon NXT roll out was in East London, Eastern Cape. Additionally, the study also aimed to understand the views health care providers have of the Implanon NXT. Methods: A retrospective crosssectional design using existing data from family planning registers and distribution of questionnaires to Health Care Providers responsible for insertion and removal of the method (HCP). Results: February 2014 to March 2019, 1238 Implanon NXT insertions were done and only 266 removals in one study site. Out of the 266 participants, 67.7% of the participants removed the Implanon for reasons other than ill health (side effects), while the remaining 32.3% had experienced side effects and opted for early Implanon removal. Bleeding was the most common side effect reported by 44 of 266 (16.5%) participants. The health care providers who completed questionnaires for this study were overall confident in providing the Implanon NXT services. Conclusion: Implementation of a new contraceptive method requires clear standardised policies and guidelines on counselling and management of side effects. Findings of this study are reassuring that Implanon NXT had a role to play in prevention of unintended pregnancies. Implementation and rollout in one site reviewed has been demonstrated to be successful. The respondents in this study possesses knowledge about the Implanon NXT.

  • Description: The objective of the study was to determine meat quality, fatty acid (FA) composition and shelf-life stability of longissimus muscle of Nguni heifers fed incremental levels of Opuntia ficus-indica (cactus) cladodes. A total of 32 heifers aged 36 months were allocated randomly to four dietary treatments: 10% cactus, 20% cactus, commercial and control diets for 90 days. The longissimus thoracis et lumborum (LTL) samples were taken from each carcass for the determination of meat quality, retail shelf-life stability and FA composition. Diet had no effect (P > 0.05) on pH and drip display, however, there was an increase in drip display with ageing time (P ≤ 0.05). Meat colour attributes (L* a* b* and C*) were influenced by diet, with 20% cactus diet having lower L* values compared to other diets (P ≤ 0.05). During a 14-day retail display, a diet  day interaction was observed for hue angle with the cactus diets having the lowest values at day 14 of display compared to the other diets (P ≤ 0.05). Differences in meat from heifers fed different diets were observed with 20% cactus accounting for significantly (P ≤ 0.05) higher levels of deoxymyoglobin and the lowest levels of oxymyoglobin. Thawing loss and Warner Bratzler shear force decreased (P ≤ 0.05) with ageing period. Meat from heifers fed cactus diets had lower (P ≤ 0.05) proportions of oleic acid (C18:1n9c) and total MUFA, higher (P ≤ 0.05) proportions of total SFA, C15:1, C17:1, linoleic acid (C18:2n6c) and total PUFA. The control diet produced meat with the highest thiobarbituric acid reactive substances (TBARS) values compared to other diets (P ≤ 0.05) and with ageing TBARS values increased (P ≤ 0.05). Diet showed an effect (P ≤ 0.05) on sensory attributes such as overall tenderness and mouth feel with cactus diets accounting for lower scores. However, juiciness, overall tenderness, grassy and animal like attributes increased with ageing (P ≤ 0.05). Inclusion of cactus in the diet did not produce any adverse effects on meat quality, fatty acid composition, lipid oxidation and sensory quality. Therefore, it can be concluded that inclusion of cactus in Nguni heifer finisher diets up to 20% can improve meat quality.

  • Description: This study explored ‘’Binge drinking: challenges faced by high school youth in Bonxa village in Ntabankulu in the Eastern Cape Province of South Africa’’. The study sought to achieve the following specific objectives; to determine factors that lead to binge drinking among high school youth, to examine the high school youth perceptions of binge drinking on their school performance and to establish gaps inherent in the laws and policies that governs alcohol consumption among the youth in South Africa. The study was premised on the theoretical lens of alcohol myopic theory by Steele and Josephs. Methodologically, the study used the qualitative approach. It also adopted exploratory and descriptive types of research design, and the case study as a specific study design. Data was gathered through in-depth one-on-one interviews, complimented by focus group discussions and key informant interviews data collection methods. Non-probability sampling was employed in selecting the study sample, which was done through both snowballing and purposive sampling techniques. This study used a sample of Thirty five (35) participants; six (6) parents, thirteen (17) school going youth, four (4) social workers, five (5) teachers and three (3) police officers who came in as key informants. Thematic analysis was used to analyze data since the study itself was qualitative. The findings of the study revealed the following issues as causal factors of binge drinking among high school youth; psychological deficit, dysfunctional families, negative role modelling, discrimination by teachers, cognitive impairment, poor academic performance, fear of rejection, poor socio-economic conditions and cultural rituals. The findings discovered gaps in policy formulation; although the country has laws governing alcohol consumption, there seems to be less monitoring in rural areas, as taverns operate without licensing. Further, awareness campaigns through advertisement in the media on the dangers of alcohol, as well as educational campaigns at schools are needed. Based on the evidence gathered in this study, the following recommendations are made; the need for deliberate programs to help youth who have binge drinking problems, stronger policy iv formulation, and strengthening of social worker services in order to address and alleviate the problem of binge drinking.

  • Description: This study examines the validity of the triple deficit hypothesis for a selected number of SADC countries, utilising secondary annual data for the period 1996-2018. Based on previous studies and theory, current account deficit was chosen as the dependent variable and budget deficit and the savings gap as the independent variables. The study makes use of both first generation and second-generation unit root tests to examine the time series properties of the data. The empirical results show that the data is integrated of different orders. Kao, Pedroni and Westerlund cointegration tests were carried out to examine the long-term relationship between the variables of interest. The empirical results revealed that there is a long-term relationship between current account deficit, budget deficit s and the savings gap. The long-run model under the Autoregressive Distributed Lag test revealed that, a positive and significant relationship exists between budget deficit and current account deficit at a significance level of 10% and a negative and insignificant relationship exists between savings gap and current account deficit in the long run. This suggests that an improvement in the current account balance in SADC countries requires fiscal stringency

  • Description: The significant positive relationships between workplace spirituality and organisational citizenship behaviour, as well as between centrality of religiosity and oganisational citizenship behaviour among police officers, confirm the relevance of social exchange theory and affective events theory to police officers’ behaviour. This study confirms the applicability of Social Exchange Theory (SET) and Affective Events Theory (AET). The current study utilized the SET and AET to examine the correlation between workplace spirituality and centrality of religiosity as well as organisational citizenship behaviour among Police officers in the Raymond Mlaba Local Municipality of the Eastern Cape. There is limited previous research concerning the influence of workplace spirituality and centrality of religiosity on organisational citizenship behaviour among police officers in the South African Police Services (SAPS) Department. A quantitative cross-sectional survey was conducted. The sample (N= 100) consist of Police officers from Raymond Mhlaba Local Municipality Police stations. Data were collected through the questionnaire method and SPSS was used for data analysis. A correlational analysis coupled with a simple linear regression analysis was utilised to determine whether there existed any significant relationship with the study’s theoretical attributes. The results of the simple linear regression indicated that workplace spirituality is positively correlated with organisational citizenship behaviour; which is similar to the centrality of religiosity. The results from multiple linear regression showed that the centrality of religiosity does moderate the correlation between workplace spirituality and organisational citizenship behaviour. The results of Multiple linear regression also showed that Workplace spirituality and centrality of religiosity both account for an extensively higher proportion vi of variance in organisational citizenship behaviour than in any of the two variables. This study augments existing knowledge on workplace spirituality, the centrality of religiosity and organisational citizenship behaviour among Police officers in the Raymond Mhlaba Local Municipality, which has largely been ignored by previous researchers, validates certain aspects of the SET and AET. The Station Commanders or Captains should give consideration on how to make the workplace more conducive to the centrality of religiosity and workplace spirituality; so that the Police officers can increase their organisational citizenship behaviour. Strategies need to be implemented to improve managerial and coworker support for Police officers through socialization and team building activities. However, to overcome feelings of occupational stress and their effects on well-being, employers should provide adequate information on any changes in the police service that may entail excessive work demand and dangerous working conditions.

  • Description: Child marriage is defined as any marriage where one of the spouses is younger than 18 years old. A number of deep, complex, interrelated and interlinked factors are responsible for the practice in Zimbabwe and elsewhere. These include the weak enforcement of existing laws, legal contradictions, slow alignment of laws to the Constitution and international child rights, entrenched harmful religious and cultural practices, and acute poverty. It was at the fulcrum of this dissertation thus to examine the unfair limitations caused by child marriage, on the realisation and enjoyment of child rights in Zimbabwe. The United Nations International Children’s Emergency Fund reported an estimated 31 percent prevalence of the scourge in the country. These percentages translate to millions of children, and the numbers could be on the rise. Child marriage has intense consequences for the realisation and enjoyment of rights by many children in Zimbabwe. Of note, child marriage ends childhoods. It impairs the children’s right to education, minimises their economic opportunities and fair chances in life, and increases their vulnerability to domestic violence, marital rape and sexually transmitted diseases. The grave ramifications of child marriage, in terms of the realisation of child rights have led to a number of international, regional and national efforts to curb this scourge. However, owing to an array of multifaceted and complex causes, the practice remains highly prevalent in Zimbabwe. After decades of side-lining, child rights in Zimbabwe, have finally gained constitutional protection under the 2013 Constitution. While the comprehensive protection of child rights as justiciable rights is an acceptable standard, a plethora of practices such as child marriage are a practical and real threat to the realisation of these rights. Therefore, it is incumbent upon Zimbabwe to ensure that child rights as stipulated in the Constitution are respected, promoted, protected and fulfilled. The elimination of child marriage is a daunting yet possible task. Through desktop based qualitative research, this dissertation ascertained the main drivers of the practice in the country, and its impact on the realisation of fundamental child rights in Zimbabwe. The study further explored the contribution, as well as the insufficiencies of International and African Human Rights systems, to the protection of children from child marriage. It also assesses the prospects and challenges of the existing domestic (legislative and constitutional norms) in protecting child rights in the Southern African country. The impetus behind this iii examination is to recommend a comprehensive and holistic effort to curb child marriage and suggest a consolidated legal and non-legal approach to end it

  • Description: Uptake of contraceptives to prevent unwanted pregnancy among sexually active teenagers in South Africa remains low as evidenced by the high prevalence of unwanted pregnancy and unsafe abortions among adolescents. This is happening despite the wide availability of contraceptives which are also offered free of charge and in a context where comprehensive sexuality education is provided from primary school level. There is limited evidence regarding contraceptive use among teenagers in South Africa, which limits the decision making on targeting for promoting use of contraceptives. To address this gap, a quantitative cross sectional study of women aged 13 and above was conducted in Mdatsane Township to investigate the factors associated with contraceptive use among teenagers and compare this with young women aged 20 and above, as well as to assess if there are any associations in the use of contraceptives between the demographic characteristics of the teenagers and their caregivers. The study findings showed that non-use of contraceptives was 53.3%. Teenagers were significantly less likely to use contraceptives, OR 0.31, 95% CI (0.18 – 0.530), more likely to use injectables OR 3.48 95% CI 1.99 – 6.08, more likely to identify partner issues being reason for not using condoms OR 10.60, 95 % CI (2.01 – 55.94). Teenager were more likely to have Termination of unwanted pregnancy on the past (TOP), OR 2.13 95% CI (1.03 – 4.38), and would likely choose Depo/Petogen even if it increases HIV transmission OR 3.65, 95% CI (1.98 – 6.73). Teenagers were more likely to have been exposed to sex education and less likely to have a close relationship with caregivers OR 0.49 95% CI (0.27 – 0.90). In view of these findings it is logical to argue that although teenagers have accessed CSE they have not been able to translate it into action. Hence the need to develop the strategies that can help facilitate behaviour change. Further in-depth studies must be conducted to establish which types of contraceptives are preferred and acceptable to teenagers. Promote self-efficacy of teenagers to be empowered to make own decisions and not put their partners’ preferences on use of contraceptives and continue promoting primary and secondary abstinence while also encouraging delayed sexual debut

  • Description: Currently more people reside in urban areas than previously. The population shift from rural to urban results in increased problems with Public Safety. Public Safety initiatives were introduced to address such issues and help reduce the increasing number of urban problems. It is the citizen's responsibility to report the Public Safety issues they observe or experience for authorities to respond quickly in emergency situations, thus maintaining a safer living environment for all citizens. A Public Safety Smart City Project was introduced in the city of East London, South Africa to help improve Public Safety in the city. However, for this to be successful citizens need to contribute by reporting Public Safety issues and suspicious activities. This study is therefore focused on motivational factors to improve citizen participation in a Public Safety Smart City Project. The Design Science Methodology and a mixed method approach guided this research study. Keller’s (2010) Attention, Relevance, Confidence, Satisfaction (ARCS) Theory of Motivation provided the theoretical base for this study. A questionnaire was used to gather data on the motivational factors for participation in a Public Safety Smart City Project. Five Critical Success Factors were developed to motivate citizens to participate in a Public Safety Smart City Project. These Critical Success Factors are: Ensure user satisfaction by providing a toll-free number, Citizens should be able to participate due to their concerns of safety for others, Citizens should be given the opportunity to make a difference in their community, Public Safety initiatives must provide adequate response to citizens and Citizens should be given incentives after participating. The Critical Success Factors were refined and verified through two rounds of expert review. Five factors were identified in the findings as factors that contribute towards motivating citizens participate. These factors include User Satisfaction, Making a difference, Response from Public Safety initiatives, Concern of safety for others and Incentives. The factors were included on the Critical Success Factors

Derivative actions in contemporary company law: A comparative assessment from an enhanced accountability perspective

  • Description: The company is one of the most popular organisational vehicles for conducting business. The very nature of the company as a juristic person is attractive. The principle of legal personality entitles a company to act as a legal entity separate from its members. The principle was laid down in the landmark decision of Salomon v Salomon 1897 AC 22 (HL). This decision shows that a company is a full player in the legal arena. It has standing before the courts of law and is the proper plaintiff for wrongs done to it, not any of the stakeholders who may also be affected by the wrongdoing. However, it has to be noted that a company is just an artificial person. It is a fictitious being, a juristic person and a creature of statute. Therefore, even though a company has the capacity to acquire rights which can be enforced in a court of law and obligations which another legal subject can enforce against it, a company cannot in all respects be equated with a human person, for it has no physical substance. Inevitably, a director must act as its hands, brain, legs, mouth and eyes. Regardless of how financially strong a company can be, its juristic nature places all its resources and wealth at the mercy of its directors and officers. A company can neither protect itself against wrongdoing, vindicate nor enforce its rights without its representative directors and officers. If the wrongdoing faction in a company comprises of directors who are required to act in the best interests of the company, then who will enforce the company’s rights? The juristic nature of a company makes it vulnerable to abuse, especially by directors. It is important to note that internal stakeholders such as directors innocent of wrongdoing, employees and shareholders are not the only ones who stand to lose from the failure of corporate governance. External stakeholders’ interests too are vulnerable to abuse as a result of a company being abused by its leaders. There is, therefore, a need for a mechanism that controls abuse of power especially by agents of a company. Such a mechanism is critical to accountability as it protects the company from director malfeasance while promoting adherence to corporate governance principles in general. Also, successful derivative claims play a significant role in securing compensation for the company. Seeing that a company can be injured by both internal and external stakeholders, it is imperative that there be an effective and efficient mechanism that protects both the company and its owners without deterring entrepreneurship and stakeholder participation. Proceeding from an iii accountability enhancement perspective, this study undertakes a comparative assessment of the derivative action as a mechanism that created to deal effectively with the mischief revealed in the above paragraphs. For a complainant to be able to invoke the derivative action for relief, he or she must comply with certain requirements. Those requirements will be examined in greater detail with respect to the American, South African, English and Japanese laws. Empirical research has concluded that directors’ exposure to derivative claims remains largely theoretical. The critical question is whether the requirements for commencing or continuing a derivative action are too onerous. Although the remedy is available in theory, its shortcomings appear to make derivative actions almost impossible to invoke in practice. It has been argued that the greatest impediment to a derivative action by minority shareholders arises from the practical barriers to the commencement of derivative proceedings. With respect to the USA, it has further been demonstrated that there is a positive correlation between the significant decline in the importance of derivative litigation and the creation of additional legal hurdles in breach of directors’ duties cases. This study seeks to examine the various shortcomings of the remedy and suggest ways to make it less onerous as well as increase its availability to more stakeholders

  • Description: __iFogSim is a toolkit to model, simulate and evaluate networks of Fog computing, Edge computing and Internet of Things (IoT). This framework provides the capabilities of analysing and evaluating the performance of applications and resource management policies in Fog/IoT environments, based on which designers can model and test their applications. This thesis proposes a novel application model of a traffic surveillance vehicular network application through smart cameras using iFogSim, where the scenario of multiple vehicles tracking is considered. The effectiveness of the proposed application model is assessed and validated by simulations using a modified application model inherited from a case study of intelligent surveillance through distributed camera networks introduced. Simulations are conducted using the iFogSim tool and performance evaluation is done. The comparison between one vehicle and multiple vehicle tracking is done and the results demonstrate that the multiple vehicle application model achieves a better performance in terms of average latency and data transfer rate
