- Description: The unique historical stressors linked to South Africa’s apartheid legacy, continues to manifest in the form of economic exclusion, social exclusion, inequality and poverty, with parents being subjugated to service users and extenders rather than included as service advocates, particularly in the child justice system. Furthermore, policies and practices do not include, engage and support parents on an intra and interpersonal level. Parents of children in conflict with the law, experience their children’s charge or arrest as well as their subsequent journey through the child justice system as a crisis resulting in their need for emotional, informational, practical and professional support during the child justice process. The similarities and differences between the contexts of child protection and child justice in supporting parents illuminates the existing gaps in child justice legislation, policy and practice resulting in a lack of support for parents during the child justice process. In the Children’s Act 38 of 2005, it is recognised that parents have a legal responsibility towards their children and that in fulfilling this responsibility parents can access support services to assist them when they face challenges in fulfilling this responsibility. In contrast, despite 80 percent of children in conflict with the law being released into parental care and parents expressing the need for support in fulfilling their parental responsibility, in this regard the Child Justice Act 75 of 2008 fails to make provision for parents to access support services. The child justice system’s narrow focus on parents as service extenders contributes to parents’ being excluded from targeted support services resulting in parents’ support needs not being addressed. The lack of programmes and services aimed at supporting parents highlight the need for coordinated services that address the multiple stressors parents are exposed to. To this end, this study was aimed at coconstructing a practice model for supporting parents of children in conflict with the law. The theoretical lenses employed in the current study namely; the Ecological systems model and the Buffering effect model describes the various systems parents need support from and the type of support they need from their family, community and professionals. Guided by a qualitative approach, the present study integrated applied research, in particular intervention design and development with participatory action research as it allowed systematic collaboration during the research process to ensure rigour. This study involved participants from two research sites namely, the Nerina One- Stop Child Justice Centre in Port Elizabeth and the Reception, Assessment and Referral office at the Uitenhage magistrates’ court. Employing a non-probability purposive sampling method, this study facilitated the participation of parents of children in conflict with the law and child justice officials who met the inclusion criteria, in the co-design and development of a practice model for supporting parents of children in conflict with the law. Participants assumed an expert and collaborative role, which enabled the co-construction of knowledge, meaning and innovation of the practice model. Qualitative data collection methods namely, twelve focus groups and thirty two participant observations, were used to explore, co-construct, describe and design a practice model for supporting parents of children in conflict with the law during the child justice process. Thematic analyses was employed to condense the data, search for codes, categories, themes, relationships and patterns in the data. Due to the research approach and design, data analysis was ongoing and informed design and development of the practice model. Based on the thematic analysis and synthesis both descriptive and analytic themes emerged. To ensure trustworthiness, this study employed various strategies to strengthen commitment, rigour, transparency and coherence. In addition, the participative research process, the inclusion of multiple forms of qualitative inquiry and the significance of the study contributed to the validity and quality of the study. Ethical considerations applicable to the study included participants’ voluntary participation, their informed consent and ensuring participants’ privacy or maintaining confidentially. Various strategies were employed to prevent or minimise risk to participants. The findings showed that formal sources of support, in particular, offer opportunities for parents to access individual and family counselling, parenting advice, and peer support. The study also highlighted the importance of recognising parents as a subsystem in the child justice system offers potential opportunities for inclusion of parents as co-facilitators of parenting programmes or support groups, as peer supporters during the child justice process. Parents’ inclusion as a partner in the child justice system is highlighted as an opportunity for parents to be able to vi participate in child justice fora, oversight committees and accreditation committees to influence policy, services and budget allocations for services to support parents of children in conflict with the law. This study’s contribution to the existing body of knowledge is an integrated, multidisciplinary, multi-phase co-constructed practice model that would enable inclusion of, and support for, parents of children in conflict with the law prior to, during and after the child justice. The co-constructed practice model (a) involves a continuum of parent-centred support for and inclusion of parents prior to, during and after the child justice process; (b) advances an inclusive and collaborative child justice system that views parents as important stakeholders in determining the type of services they need and being involved in developing practice; and (c) promotes parents as equal partners in decision making and policy making to influence legislation, policy and practice in the child justice system.

- Description: This study explores Acculturation and Coming of age not only as a social process but also a psychological one. The constructs are examined in line with Freudian psychoanalytic theory. The study focuses on migrant inclination of two female African writers, Tsitsi Dangarembga and Chimamanda Adichie in Nervous Conditions and Purple Hibiscus respectively. Through the study, it is discovered that acculturation involves both cultural and psychological change or adaptation and failure in either can result in trauma or produce socially imbalanced individuals. In other to have a healthy coming of age, family and the home status play a very significant role in the totality of an individual and also serves as a microcosm of social and political milieu. Also, the study in the course of the study, we discover there is no ‘authentic African culture’, culture is non-static and so, the study also discusses culture as being transnational and translational. The writers’ consciousness of space and place in their writing through reminiscent times of childhood play significant roles. Childhood figures are constructed in a matrix of concrete memories, spaces, places and times that play a significant role in the production of meanings of their migrant identities. The study identifies ways in which female socialisation further enhances her marginalisation in the society and how the family in the African setting as an ideological state apparatus contributes in ensuring the marginalised position of women. The authors being studied interrogate methods of raising children among African families in contemporary society

- Description: This treatise seeks to describe the legal protection of children against child labour in South Africa. It does so within the context of international-law-protection in the form of Conventions of the International Labour Organisation. The treatise distinguishes between the concepts of child labour and child work and traces the history of international law prohibiting and regulating child labour. The two most important ILO Conventions, Convention 138 of 1973 and 182 of 1998 are considered in some detail before the national legislature is explained and analysed. From the discussion it is apparent that South Africa is giving effect to the applicable ILO Conventions. Not only does national legislation prohibit child labour, the state also adopted nation-wide programmes to eradicate child labour. Despite the efforts there is still room for improvement. The fight to eradicate child labour must continue!

- Description: The study was undertaken to investigate whether a teaching tool Concept Cartoons may assist Intermediate Phase (IP) Natural Sciences teachers with the development and understanding of scientific jargon, when implemented in Natural Sciences investigations. As a novice Natural Sciences teacher it was important to find a teaching tool which would assist second language learners with scientific concepts, particularly focusing on science investigations. The focal aim was to search for a fun, captivating, educational resource that would cater for these learners’ barriers to science learning. This research falls within a constructivist worldview, and the research method employed was a case study. Data were collected through qualitative approach, via semi-structured interviews. A total of nine participating Intermediate Phase Natural Sciences teachers from the Port Elizabeth Northern Areas schools contributed towards the findings of this study. This study was an investigation undertaken to see whether a different teaching approach may encourage change. The findings of this study suggested that Concept Cartoons used in Natural Sciences investigations created an educational effect towards the learners understanding of science concepts. Intermediate Phase learners were introduced to Concept Cartoons to assist with their understanding of science terminology during practical investigations. The results of this investigation suggested that Concept Cartoons assisted English second-language learners with scientific jargon and served as an educative curriculum material for Intermediate Phase teachers. Furthermore Grade 4 findings suggested English home-language speakers struggled with scientific language, compared to their second-language peers who achieved greater results due to the amount of effort and determination they dedicated to translating these concepts.

- Description: Health benefits associated with regular physical activity (PA) have been widely established. Regular PA is not only associated with improved physical and psychological well-being, but also with improved brain function and cognition, thereby enhancing academic performance (AP). Despite these benefits, decreasing levels of PA and increasing levels of overweight and obesity exist world-wide, making childhood physical inactivity a global concern. Research suggests children who meet the recommended PA guidelines of 60-minutes of moderate-to-vigorous intensity attain substantially higher academic grades. Schools provide ideal settings for PA promotion due to the substantial amount of time children spend at school. However, in many countries, including South Africa (SA), Physical Education (PE) programmes have been reduced and replaced with other subjects to increase AP. Furthermore, a scarcity of water, limited accessibility to improved sanitation and lack of personal hygiene at home and in school substantially contributes to the burden of preventable childhood diseases. These hygiene-related illnesses augment the cycle of poverty and disease through its detrimental effect on children’s school attendance, academic performance and productivity. Studies also show that obesity, poor nutrition and food insufficiency affect children’s school achievement. Hence, the school environment plays an essential role in improving children’s health, since many teaching opportunities about important health and nutrition practices are provided. The primary aim of this study was to determine the effect of various combinations of school-based interventions on the attention and AP of primary schoolchildren from disadvantaged communities in Port Elizabeth. Overall, 857 schoolchildren (n = 434 boys and n = 423 girls, aged 8 – 13 years) participated in the study. A 10-week cluster randomised controlled trial using four experimental and four control schools was conducted. Setting-specific interventions incorporated PA, health and hygiene education and nutrition components. The d2 Test of Attention measured selective visual attention and concentration with outcome measures of the percentage of errors, total performance and concentration performance. End of year school results were used to assess AP. Post-intervention and pre- to post-intervention differences between the inter-school comparisons revealed mixed results for the attention and AP measurements, therefore, no conclusions could be drawn regarding the assessed variables. Intervention group comparisons at post-intervention indicated that the PA intervention group achieved a statistically significant improvement (p < .05 and d > 0.8) for AP, when compared with the non-PA intervention group. No significant differences were found for AP in relation to intervention group comparisons for the health and hygiene education and nutrition intervention groups. Similarly, the intervention group comparisons revealed no significant differences regarding attention for post-intervention and pre- to post-intervention differences. Findings suggest that a school-based PA intervention can positively affect children’s AP. The current study emphasises the necessity of PA and reinforces the importance of PE in the school curriculum. Therefore, it is strongly recommended that PE regains its rightful place and be actively taught within the school curriculum.

- Description: Despite the initiation of life-long ART in HIV-infected pregnant women, the rate and determinants of infant HIV transmission are not known, especially in the poor resource settings of the Eastern Cape, South Africa. Maternal anti-retroviral therapy (ART) is crucial for elimination of mother-to-child transmission (MTCT) of HIV. However, the inevitable risks of emergence of HIV drug resistance poses significant threat to achieving this goal of HIV-free generation and keeping mothers alive. Also, it is unclear if women with high viral load at delivery have acquired clinically relevant mutations, which could confer resistance to the ART, thus, further increasing the risks of motherto-child transmission of HIV-drug resistance strains. In addition to the gaps identified in the prevention of mother-to-child transmission (PMTCT) context, the understanding of regional epidemics is crucial to the broader epidemiological profiling of HIV infections in the country. Despite the rapid influx of foreign nationals to South African and Eastern Cape Province, there has not been any molecular epidemiological studies profiling the HIV diversity in the Eastern Cape.

- Description: The study investigated risk and adoption of mobile financial services among some users in selected municipalities within the Eastern Cape Province, using the theory of reason action, technology acceptance model and the theory of expected utility and risk aversion to explain the variables. Moreover, the explanatory research design and quantitative data collection approach formed the methodology adopted in the study. In addition, a validated semistructured interview questionnaire was used as a research instrument in the study. The multistage, stratify, purposive and convenience sampling techniques were applied to select 6 research sites and 386 research participants for the study. Three research objectives were stated and tested using descriptive, Principal Component Analysis (PCA) to profile the risk and logit regression statistics. The results of statistical analysis show different level of cross tabulation between MFS and education level, all the 6 different locations, individual age range, job type, and average income of individual. Analysis revealed that age and income level of individuals have the highest relationship with the use of MFS. The statistical analysis used was the logistic regression. Pool of effort of all the stake holders in financial services sector should focus on including the low income earners and the technology should be simple enough for the use of the older generation.

- Description: The study investigated risk and adoption of mobile financial services among some users in selected municipalities within the Eastern Cape Province, using the theory of reason action, technology acceptance model and the theory of expected utility and risk aversion to explain the variables. Moreover, the explanatory research design and quantitative data collection approach formed the methodology adopted in the study. In addition, a validated semistructured interview questionnaire was used as a research instrument in the study. The multistage, stratify, purposive and convenience sampling techniques were applied to select 6 research sites and 386 research participants for the study. Three research objectives were stated and tested using descriptive, Principal Component Analysis (PCA) to profile the risk and logit regression statistics. The results of statistical analysis show different level of cross tabulation between MFS and education level, all the 6 different locations, individual age range, job type, and average income of individual. Analysis revealed that age and income level of individuals have the highest relationship with the use of MFS. The statistical analysis used was the logistic regression. Pool of effort of all the stake holders in financial services sector should focus on including the low income earners and the technology should be simple enough for the use of the older generation.

- Description: This thesis is a social history of malaria in southwestern Nigeria. It contributes to the burgeoning literature in the historiography of medicine, specifically the medicine and empire debate. Key to the issues raised in this thesis is the extent to which the limitations in colonial medical policies, most especially malaria control programmes, inspired critical and ingenious responses from African nationalists, doctors, patients, research volunteers, and indigenous medical practitioners. Challenged by a wide range of diseases and a paucity of health facilities and disease control schemes, African rural dwellers became medical pluralists in the ways they imagined and appropriated ideas of Western medicine alongside their indigenous medical practices. Beginning with a detailed historical exploration of the issues that informed the introduction of curative and preventive medicine in southwestern Nigeria, this thesis reveals the focus of colonial medicine. It exposes the one-sided nature of medical services in colonial spaces like southwestern Nigeria and the ways it shaped multifaceted responses from Africans, who were specifically side-lined till the 1950s when the rural medical service scheme was introduced. The focus of colonial medicine is drawn from relatively rich but often subjective historical evidence, such as a plethora of official reports of the department of medical and sanitary services, official correspondences within the colonial government in Lagos and Nigeria, and between the colonial government and the colonial office in the United Kingdom. Details of African responses to medical policies were garnered from newspaper publications and correspondences between the African public and the colonial government in Lagos. They reveal very interesting details of the ways Africans imagined, reimagined, and appropriated malaria control ideas and schemes. The central argument in this thesis is that attempts to control malaria in southwestern Nigeria till the 1950s, were shaped by a single concern to ameliorate the implications of the disease on the colonial state. It argues that this one-sided nature of malaria control programme informed the basis for medical pluralism in most rural spaces where African communities became patrons and sponsors of Western medicine and at the same time custodians of their indigenous medical practices. The series of justifications for the sustenance of these services were reinforced on the basis of the failure of the colonial state to guarantee the health needs of their colonial subjects. The aim of the thesis is to reinforce arguments that portray colonial medicine as a “tool of empire” but goes a bit further to explain the extent to which Africans related to this reality. It states quite categorically that Africans were not docile and silent, but that they acted decisively in ways that suited their varied interests and courses.

- Description: This research examined the use of a personnel performance appraisal, a component of performance management system to evaluate employees at the Southern Operation Region Office of the Department of Water and Sanitation, Port Elizabeth and how this affects their performance. Writers in the available literature, contend that the objective of performance appraisal policy is to review work performance and provide feedback to facilitate measures and programmes to improve employee performance. Cascio and Aginis (2011:73) write that performance appraisal is a systematic description of individual or group job-relevant strengths and weaknesses as an important part of a performance management system. The study firstly analyses the effectiveness of performance appraisal in evaluating the management of the utilisation of resources. Secondly, the appropriateness of the tool in assessing the capacity of employees and contributing towards facilitating programmes and training to develop employee effectiveness. Thirdly, the study also examined the perception of employees on the use of performance appraisal as a management tool in the Department of Water and Sanitation Regional Operation Office. The study adopted a mainly qualitative methodological approach and purposively selected a sample of 30 employees at the Southern Operation Region Office of the Department of Water and Sanitation in Port Elizabeth who completed the questionnaire for the study. The choice of the qualitative research methodology is due to the fact that the approach is well suited to the collection of in-depth and perceptual information and for discovering underlying motivations and perceptions of the employees as respondents. The general employees at the area chosen for the study is one of a relatively young employee profile. The average age of the employees is about 28. The findings revealed that competence, assessment and development, communication and the adequate training which employees received based on the performance appraisal all had an impact on employee performance in Department of Water and Sanitation. Furthermore, factors, such as employee training, competence and communication could not be ignored since they were rated to a moderate extent v by the employees and it also contributed to employee performance. The study findings specifically highlight the importance of effective communication between the employer and the employees in order to improve employee performance appraisal processes. The study recommends a set of guidelines which could be used in improving the current performance appraisal policy and further boost employee performance.

- Description: This study analyzed the effects that spatial arrangement of petroleum products retail outlets and the supply chain management techniques employed for products distribution (for both intra city and intercity shipments) have on the retailing dynamism of petroleum products within built environment and peripherals of Ibadan metropolis over the years. Specifically, the study investigated the differentials in the spatial configurations of petroleum products retail outlets between the core and periurban zones of the metropolis. An attempt was made to determine the explanatory variables that influence the spatial distributional decisions of petroleum products retail outlets in the metropolis. The study equally examined how the supply chain management (SCM) techniques by the different categories of the retail outlet owners influence the efficient and cost effective distribution of petroleum products. Lastly an attempt was made to analyze the relationship between the socio-economic attributes of the haulers and the achievement of compliance to the HSE stipulations guiding the conveyance of petroleum products. The theoretical underpinnings for the research were a derivative of the amalgamation of normative and psychological theories from geography, psychology, SCM and retailing science. Specifically, Expectation Disconfirmation Theory (EDT), Distributive Justice, Central Place Theory (CPT) Theories of Urban Impact (TUI) and Theory of Constraint (ToC) were the theories utilized in the study. For the achievement of the first objective which was to investigate the possible differential in the compliance rate between spatial pattern of fuel retail outlets in the core and peripheral zones of Ibadan metropolis, the first hypothesis of the study (which examined if there was no significant difference in the rate of compliance to the planning authority stipulations guiding the location pattern of petroleum product retail outlets between those located in the built up and xxiv peripheral zones of the city), was tested through the use of buffering and proximity analyses in the ArcMap environment of ArcGIS 10.1, while inferential statistical tool of an independent-samples t-test was conducted to compare the rate of compliance to the stipulations guiding the locations of these outlets in both the core and the peripheral zones. The result from the GIS analysis indicated that 33 (15.56%) out of the 220 outlets in the core zone of the metropolis complied with the planning stipulations guiding the location of fuel retail outlets. For the peripheral zone, out of the 220 fuel retail outlets 24 (10.90%) complied with the stipulations. The result from the t- test which was employed to test the hypothesis indicated that no significant difference existed in the rate of compliance t (263) =-2.66, p = 0.08 between fuel retail outlets in the core zone (M=3.9, SD=1.4) and peripheral zone (M=4.5, SD=1.79). The alternate hypothesis which stated that ―no significant difference existed in the compliance rate between fuel retail outlets located in the two zones‖ is accepted. For the achievement of the second objective of the study which was to analyze the factors which determine the location of fuel retail outlets both in the core and peripheral zones of Ibadan metropolis. All the managers/owners of the 432 fuel retail outlets in the metropolis were sampled out of which 256 questionnaires were retrieved for the purpose of this analysis. The breakdown of the socio-economic characteristics of the sampled respondents showed that the gender distribution showed that 194 (75.78%) of the respondents were males, while 64 (24.22 %) were females. The average age of the sampled population was 33.70 years. The mixed method was employed for the achievement of the second objective of this study. Logistic Regression Model (LRM) was employed to test the hypothesis and the result revealed that the inclusion of the independent variables in the model increased the overall level of it accuracy. The overall significance revealed that the Model Chi- xxv Square, derived from the likelihood fitted is also accurate (X2 = 43.47, df=5, p>.05). The model chi-square value of 43.47 (approximately 44% ) was significant. Thus, the indication is that the model has a good fit in predicting the possibility of a fuel retail outlet being located in the core or peripheral zone of the metropolis as determined by the explanatory variables (the independent variables accounted for about 44% of possible factors which determined whether a fuel retail outlets is located either within the core or peripheral zones of the metropolis. The remaining 56% are factors not considered in the study). The result gotten from the in depth interview sessions corroborated the findings from the tested hypothesis. The third objective was to examine the effects which the supply chain technique employed (either vertically integrated model or third-party arrangement) has on the achievement of efficient and effective distribution of the products. In order to achieve this objective, all the 389 registered members of Petroleum Tanker Drivers (PTD) association who are members of the PTD in the metropolis were sampled, 265 (around 70%) of the distributed questionnaires were retrieved and used for the analysis. In depth interview sessions were also conducted with three different managers of the three major conglomerates in the downstream sector of the Nigerian petroleum sector. The result of one-way between subjects (ANOVA) which was conducted to compare differences in the management and performances of haulage services outsourced to the 3PLS and those run under VIM showed that there was a significant effect of ownership type on management performance (F (2,262) = 60.26, p<.05). The null hypothesis was therefore rejected while the alternate hypothesis was accepted. The findings from the interview sessions posted similar results. The fourth and final objective was to analyze the effect that the socio-economic attributes of the participants (haulers and managers of retail outlets) involved in the distribution of xxvi petroleum products has on the safe, efficient and cost-effective distribution of product and this was done through the use of descriptive statistics, inferential statistics and incisive analysis of the interview sessions. A total number of 265 (70%) out of the 389 registered members of Petroleum Tanker Driver Association (PTDA) participated in the study. Multiple regression analysis (MRA) was used to test this hypothesis. The result from the statistical analysis show that the use of stimulant, work condition, marital status and educational attainment/literacy level have joint influence on compliance (R2 = 0.31, F (4,260) = 29.72, p<.05). On the basis of the foregoing, the hypothesis is thus accepted. The result from the interview sessions confirmed the existence of strong relationship between the explanatory variables and the hypothetical dependant variable. The study recommended a review of the planning processes guiding the establishment of fuel retail outlets. The study also advocated that retailers should endeavour to have stronger control over the supply chain of their products this could done by investing more in VIM rather than outsourcing such functions to 3PLs. This will help in better business performances. Government agencies in charge of monitoring drug abuse among haulers are advised to be more proactive by the duo of prevention and punishment strategies. This should include advocacy campaign against drug abuse. Different ranges of punishments should also be meted out for individual haulers found culpable.

- Description: Increased urbanization and industrialisation due to human population growth and associated high demand for food have led to widespread disturbances of freshwater ecosystems and associated resources. A widely recognised consequence of these disturbances is the excessive delivery of sediments into the freshwater ecosystems, which severely affects the functioning and integrity of these systems.. The major water quality impairment in the Tsitsa River and its tributaries, situated in the Mzimvubu catchment in the Eastern Cape Province of South Africa, is known to be excessive sediment input. In this study, the application of macroinvertebrates taxonomic-based and trait-based approaches was used to assess the responses and vulnerability of Ephemeroptera, Plecoptera, Odonata and Trichoptera (EPOT) species to settled and suspended sediments stress in eight selected sampling sites in the Tsitsa River and its tributaries. The eight selected sites were Site 1 (Tsitsa upstream), Site 2 (Tsitsa downstream), Site 3 (Qurana tributary), Site 4 (Pot River upstream), Site 5 (Pot River downstream), Site 6 (Little Pot River), Site 7 (Millstream upstream) and Site 8 (Millstream downstream). The methods used in this study involved the analysis of water physico-chemical variables as well as sediment characteristics, derivation of five EPOT metrics, EPOT species-level taxonomic analysis, individual EPOT trait analysis and the development of a novel trait-based approach using a combination of traits. The sampling of EPOT taxa was done using the SASS5 protocols. Identification of EPOT was done to genus/species level and all data were subjected to relevant statistical analysis. The results of ecological categories derived for the physico-chemical variables generally indicated the ecological categories A and B, which was indicative of good water quality conditions. The result of sediment particle analysis revealed four distinct site groups: site group 1 (Tsitsa River upstream and Qurana tributary), site group 2 (Tsitsa River downstream and Millstream upstream), site group 3 (Pot River, both upstream and downstream, and Millstream downstream) and site group 4 (Little Pot River). The species-level taxonomic analysis of EPOT revealed that site group 1 was the most sediment-influenced sites whereas site group 4 was the least sediment-influenced. Species such as Paragopmhus sp., Aeshna sp. and Baetis sp. were considered sediment-tolerant with strong positive association with site group 1. The novel trait-based approach developed in this study proved useful in predicting the responses of EPOT species to sediment stress, and further discriminated between the study sites. The approach was used to group EPOT species into four vulnerability classes. The result showed that filter feeding EPOT species that have filamentous gills, preferring stone biotopes and feeding on detritus (FPOM) were mostly classified as highly vulnerable to sediment stress and indicated no significant association with the highly sediment-influenced site group 1. The TBA largely corresponded well to the predictions made with the relative abundance of the vulnerable class decreasing in the sediment-influenced sites compared to the tolerant and highly tolerant classes. Overall, the study revealed the importance of the complementary use of taxonomic and trait-based approaches to biomonitoring.

- Description: Very Long Baseline Interferometry (VLBI) has significant advantages in disentangling active galactic nuclei (AGN) from star formation, particularly at intermediate to high-redshift due to its high angular resolution and insensitivity to dust. Surveys using VLBI arrays are only just becoming practical over wide areas with numerous developments and innovations (such as multi-phase centre techniques) in observation and data analysis techniques. However, fully automated pipelines for VLBI data analysis are based on old software packages and are unable to incorporate new calibration and imaging algorithms. In this work, the researcher developed a pipeline for VLBI data analysis which integrates a recent wide-field imaging algorithm, RFI excision, and a purpose-built source finding algorithm specifically developed for the 64kx64k wide-field VLBI images. The researcher used this novel pipeline to process 6% (~ 9 arcmin2 of the total 160 arcmin2) of the data from the CANDELS GOODS- North extragalactic field at 1.6 GHz.

- Description: Very Long Baseline Interferometry (VLBI) has significant advantages in disentangling active galactic nuclei (AGN) from star formation, particularly at intermediate to high-redshift due to its high angular resolution and insensitivity to dust. Surveys using VLBI arrays are only just becoming practical over wide areas with numerous developments and innovations (such as multi-phase centre techniques) in observation and data analysis techniques. However, fully automated pipelines for VLBI data analysis are based on old software packages and are unable to incorporate new calibration and imaging algorithms. In this work, the researcher developed a pipeline for VLBI data analysis which integrates a recent wide-field imaging algorithm, RFI excision, and a purpose-built source finding algorithm specifically developed for the 64kx64k wide-field VLBI images. The researcher used this novel pipeline to process 6% (~ 9 arcmin2 of the total 160 arcmin2) of the data from the CANDELS GOODS- North extragalactic field at 1.6 GHz. The milli-arcsec scale images have an average rms of a ~ 10 uJy/beam. Forty four (44) candidate sources were detected, most of which are at sub-mJy flux densities, having brightness temperatures and luminosities of >5x105 K and >6x1021 W Hz-1 respectively.

- Description: Though many strategies have helped in increasing students’ knowledge and awareness about environmental issues, yet, environmental challenges and problems are still on the increase in Nigeria. This may be due to the fact that environmental issues are controversial and require collaborative efforts of all citizens, especially school students. This study determined the effects of service learning and collaborative learning in social studies on Junior Secondary School students’ environmental literacy. It also explored the moderating effects of school location and gender. The study adopted a pretest-posttest, control group, quasiexperimental design. Multi-stage sampling technique was employed. Six (6) secondary schools that are co-educational from Ibadan were purposively selected based on presence of environmental challenges in their immediate environment. There were three (3) schools from Ibadan city (urban area of Ibadan) and three (3) from Ibadan less city (rural area of Ibadan). Seven hypotheses were tested at 0.05 level of significance. Five research instruments were used for the study, these were; Environmental Knowledge Test (EKT, r = 0.76), Environmental Attitude Questionnaire (EAQ, r = 0.85), Service Learning Guide (SLG, r = 0.71), Collaborative Learning Guide (CLG, r = 0.66) and Conventional Learning Guide (CLG, r = 0.73). Analysis of Covariance (ANCOVA) was used in testing the seven formulated hypotheses. Scheffé Post-hoc analysis was carried out to determine the source of significant effect of treatment. Significant interaction effect was described using graphical representation. All hypotheses were tested at P< .05 level of significance. The results revealed that there was a significant main effect of treatment (service and collaborative learning strategies) on junior secondary school students’ environmental knowledge (F(2,582) = 824.98; p<0.05, partial η2 = 0.739), with an effect of 73.9%. There was also a significant main effect of treatment (service and collaborative learning strategies) on junior secondary school students’ environmental attitude (F(2,582) = 1317.79; p<0.05, partial η2 = 0.819). The findings showed that there was a significant main effect of gender (male/female) on junior secondary school students’ environmental knowledge (F(1,582) = 3.99; p<0.05, v partial η2 = 0.007) but there was no significant main effect of school location (urban/rural) on junior secondary school students’ environmental knowledge (F(1,582) = 0.08; p>.05, partial η2 = 0.00). Based on these findings, it was recommended that teachers should adopt service learning and collaborative learning strategies in the teaching of environmental concepts and problems in Social Studies in order to improve students’ performance in Social Studies. Teachers should facilitate the use of service learning and collaborative learning strategies in schools to improve students’ environmental problem-solving skills and their achievement in the subject. Teaching institutions should not only include service learning and collaborative learning strategies in their curriculum but should endeavour to provide practical experience for pre-service teachers to be well grounded and equipped on the use of these strategies.

- Description: The study investigated whether self-regulated learning (SRL) strategies can be used successfully by Grade 3 mildly gifted learners (MGLs), in order to master an enriched advanced level mathematics curriculum. In accordance with internationally and nationally accepted principles, learners of diverse abilities should be given equal opportunities to achieve their full learning potential. The stark reality is that rigid application of the national curriculum currently used in South African primary schools, limits this ideal. MGLs possess skills that enable them to study at an increased level, a quicker pace and with an advanced degree of independence. The study employed the true experimental research. Sixty-four learners participated in the Mathematics Enrichment Programme. Purposive sampling was used to identify and select these learners. Subsequent to SRL pre-tests, simple random sampling was used to determine the experimental and control groups. The experimental group used problem-solving and 21st Century technology to develop SRL strategies. Direct teaching strategies were used for the control group. Learners were administered pre-tests, diagnostic problem-solving assessments, and post-tests relating to problem-solving and SRL. Chi-square tests and inferential t-tests were employed to draw comparisons within and between the groups regarding SRL and problem-solving scores. Univariate ANCOVAs were conducted to determine the post-test differences. Furthermore, Cronbach alpha was used to measure reliability of summated scores relating to SRL and problem-solving. The empirical results suggest that MGLs in Grade 3 are indeed capable of self-regulating their learning. This enhanced learners’ self-determination, self-confidence, self-motivation, self-independence, and self-empowerment in relation to their tasks. The empirical results suggest a significant constructive addition to the present standard curriculum for MGLs in the mainstream of education. The self-regulatory model for Foundation Phase MGLs which evolved from this study can be successfully employed to balance the diversity challenges in an inclusive education system. The findings of this study can have significant implications for future teacher training and education of MGLs in primary schools.

- Description: This study explores the construction of the identity of professional pilots through a case study of a flying school in South Africa. Here, a 15-20-month period of intensive study and training of students, fresh from school or college, leads in most cases to the attainment of a Commercial or Airline Transport Pilot’s Licence. The construction of identity is a continuous process and a lifelong project and hence this study can only reflect upon the factors influencing the early stages of a pilot’s career, until the point where the licenced Pilot leaves the Air School and enters full time employment with a commercial undertaking, but it is argued that this is a crucial step in the formation of professional identity, habitus in Bourdieu’s terms. The culture of the air School reflects the military background of the founders of the school and the staff employed in senior positions. The school, which is residential, observes a strict regime of Ground School and Practical Flying Training and a high standard of performance and personal conduct is demanded, both during training and in off duty hours and excessive consumption of alcohol and smoking are discouraged, and drug use absolutely taboo. Progress with training at the school is closely monitored and a disciplined environment maintained by surveillance cameras, house monitors and security guards; in Foucauldian terms, a modern version of the Panopticon, but somewhat less than Goffman’s Total Institution. It was found that the construction of a flying identity for most of the students entering the air school commenced in childhood or early adulthood, through the influence of friends and relatives and they enter the school with the firm intention of becoming Professional pilots. Full participation of the author in the Ground School revealed how professionalization is implemented through the discipline and rigor of the training methods employed. Through mastery of a complex body of theoretical knowledge in the Ground School and the practical skill of learning to fly in a one-on-one relationship with an instructor, the students gain confidence and efficacy which contributes to their self-respect and maturity. The international reputation of the school, confers prestige upon its graduates and they benefit from membership of a profession which commands respect and a high level of income. In large measure, the thesis shows, the success of the School is a function of the founders’ ‘invention of tradition’ focusing on the wartime training school that existed on the site and the many echoes of those times in the (re)construction of its buildings and facilities, continuing in the approach of the multinational that now owns the School.

- Description: The Management of Construction Material Logistics Systems plays a significant role in meeting the goals of cost, quality and time to completion of a construction project. Studies have revealed that the cost of construction materials is usually about 50%-60% of the total cost of the project and that the logistic cost accounts for between 17%-35% of the cost material. Fundamentally, it is accepted that any inefficiency in the delivery of construction material could lead to a time overrun and thus, a rise in construction costs addressing the operational performance of logistics would have a positive impact on the goals of a construction project. The aim of this study was to investigate and evaluate the operational performance of material logistics in North-Central Nigeria as there is little specific research conducted on its effectiveness and efficiency. The methodology used included an extensive literature review and a field study conducted on ten quantitative approach that is rooted in the positivist paradigm, and purposive sampling techniques, was adopted. The descriptive method of data analysis was employed, and the findings and interpretations presented through graphs and images. Analysis of the findings led to the conclusion that material logistics did not operate as a system. There was almost no collaboration and integration of the logistics systems to create a synergistic interrelationship between functions in pursuit of higher overall effectiveness and efficiency. Improvement was needed in warehouse and transport operations and processes; technology and automation of logistics operations were absent, and delivery of material to customers was not effective. The implication was that the current materials logistics system did not meet the delivery goals of cost, quality and time of a construction project. The recommendations suggested included the adoption of the framework developed in this study. This would serve as a guide towards effective and efficient logistics management for material manufacturing firms, and for construction professionals.

- Description: For over fifty years, the majority of the Western nations have provided foreign aid to underdeveloped countries, particularly on the African continent, claiming they wanted to bring about development and alleviate the so-called poverty trap. However, the effect of such financial transfer has not been significant in most of these countries, as many recipient countries still suffer from extreme poverty and underdevelopment. Malawi is a landlocked country found in south-eastern Africa. This small country, despite being a major recipient of foreign aid since the 1960s until the present day, continues to experience extreme poverty. Malawi is one of the world’s poorest countries, ranking 174 out of 187 as at 2013, with over 50.7% of its population living below the poverty line. Thus, this study sought to assess the role of foreign aid in poverty alleviation in Malawi over the years and particularly in the 2000-2015 period. Literature related to this study on foreign aid was reviewed to gain insight into the views of other writers on the topic under study. The study used secondary sources of data to examine the effect of foreign aid on poverty alleviation in Malawi. The study found out that, even though foreign aid to Malawi might have been provided to address poverty and economic challenges to some extent, these objectives have not been met because of donor conditionalities, poor coordination, corruption and mismanagement of donor funding. The study equally found that donors to Malawi over the years have laid much emphasis on good governance rather than poverty alleviation, hence no significant contribution of foreign aid assistance in poverty alleviation, particularly among the rural population which makes up the majority of the poor. This study recommends that to enhance aid effectiveness in poverty alleviation, there is a need for donors to revise their conditions based on the recipient country’s needs and not on donor motives. Secondly, the government of Malawi should consider establishing a legal and legislative framework that guides the use of donor funding and donor activities to ensure accountability and sustainability.

- Description: The relationship between financial inclusion and the growth of the economy is a topic of debate in the existing literature. Yet globally and at individual country level, policy makers have accepted financial inclusion as a developmental agenda. This study, therefore, empirically investigates the relationship between financial inclusion and economic growth in Ghana using quarterly time series data from 2005 to 2016. Employing the commonly used indicators, the ARDL bounds test with cointergration was applied to examine the short and the long run relationship between the variables. Furthermore, the Granger causality approach was also used to establish the direction between financial inclusion and economic growth in Ghana. The result of the findings confirmed mixed results and no clear cut relationship between the direction of causality between the indicators of financial inclusion and economic growth. The study concluded that whether financial inclusion positively or negatively impact economic growth rests on the indicators employed. The study therefore cautions in the choice of financial indicators as policy tools in designing and executing economic growth and development policies in Ghana.

- Description: The relationship between financial inclusion and the growth of the economy is a topic of debate in the existing literature. Yet globally and at individual country level, policy makers have accepted financial inclusion as a developmental agenda. This study, therefore, empirically investigates the relationship between financial inclusion and economic growth in Ghana using quarterly time series data from 2005 to 2016. Employing the commonly used indicators, the ARDL bounds test with cointergration was applied to examine the short and the long run relationship between the variables. Furthermore, the Granger causality approach was also used to establish the direction between financial inclusion and economic growth in Ghana. The result of the findings confirmed mixed results and no clear cut relationship between the direction of causality between the indicators of financial inclusion and economic growth. The study concluded that whether financial inclusion positively or negatively impact economic growth rests on the indicators employed. The study therefore cautions in the choice of financial indicators as policy tools in designing and executing economic growth and development policies in Ghana.
