Abstract Background Schistosomiasis is known to affect the cognitive functions of children, however, but there is paucity of information on its impact on early childhood development in developing countries where the disease is endemic. This study aimed at determining the effects of schistosomiasis due to Schistosoma haematobium on early childhood development in children below 5 years old from Murewa District, Zimbabwe, including the benefits of treatment. Methods Preschool age children (PSAC) under the age of 5 years were screened at baseline and at 6 months post-treatment for S. haematobium infections diagnosed using the urine filtration method. Cognitive domains were assessed using the Griffith Mental Developmental Scales III on 136 PSAC. Multivariate logistic regression was used to determine the level of association between S. haematobium infection and performance in the cognitive domains adjusting for confounding factors (i.e. nutrition, hemoglobin levels, gender and age). Median Development Quotient scores of each cognitive domain at baseline and at 6 months post-treatment were compared and quantified. Results After adjusting for confounding factors, PSAC infected with S. haematobium had greater odds of having lower scores in the Foundation of Learning Domain (OR = 3.9, p = 0.008), Language and Communication Domain (OR = 3.2, p = 0.017), Eye-Hand Coordination Domains (OR = 10.7, p = 0.001), Personal-Social-Emotional Domain (19.3, p = 0.001) and in the Overall General Development Domain (7.2, p = 0.011). Improvement of cognitive performance was observed at 6 months post treatment in the following Domains; Language and Communication Domain (p = 0.003), Eye-Hand Coordination Domain (p = 0.02) and General Development Domain (p = 0.006). Conclusion The study showed that S. haematobium infection in PSAC is associated with lower cognitive scores in the Foundation of Learning, Language and Communication, Eye-Hand Coordination, Personal-Social-Emotional and in the Overall General Development domains. Our results strengthen the call for inclusion of PSAC in routine deworming programs for the control of urinary schistosomiasis and the need to develop locally validated tools to monitor early child development in endemic areas where resources are limited. more...

BackgroundCognitive function is negatively impacted by schistosomiasis and might be caused by systemic inflammation which has been hypothesized to be one of the mechanisms driving cognitive decline, This study explored the association of systemic inflammatory biomarkers; interleukin (IL)-10, IL-6, IL-17, transforming growth factor (TGF-β), tumor necrosis factor (TNF-α), C-reactive protein (CRP) and hematological parameters with cognitive performance of preschool-aged children (PSAC) from an Schistosoma haematobium endemic areaMethodsThe Griffith III tool was used to measure the cognitive performance of 136 PSAC. Whole blood and sera were collected and used to quantify levels of IL-10, TNF-α, IL-6, TGF-β, IL-17 A and CRP using the enzyme-linked immunosorbent assay and hematological parameters using the hematology analyzer. Spearman correlation analysis was used to determine the relationship between each inflammatory biomarker and cognitive performance. Multivariate logistic regression analysis was used to determine whether systemic inflammation due to S. haematobium infection affected cognitive performance in PSAC.ResultsHigher levels of TNF-α and IL-6, were correlated with lower performance in the Foundations of Learning domain (r = -0.30; p < 0.001 and r = -0.26; p < 0.001), respectively. Low cognitive performance in the Eye-Hand-Coordination Domain was observed in PSAC with high levels of the following inflammatory biomarkers that showed negative correlations to performance; TNF-α (r = -0.26; p < 0.001), IL-6 (r = -0.29; p < 0.001), IL-10 (r = -0.18; p < 0.04), WBC (r = -0.29; p < 0.001), neutrophils (r = -0.21; p = 0.01) and lymphocytes (r = -0.25; p = 0.003) The General Development Domain correlated with TNF-α (r = -0.28; p < 0.001) and IL-6 (r = -0.30; p < 0.001). TGF-β, L-17A and MXD had no significant correlations to performance in any of the cognitive domains. The overall general development of PSAC was negatively impacted by S. haematobium infections (OR = 7.6; p = 0.008) and (OR = 5.6; p = 0.03) where the PSAC had higher levels of TNF-α and IL-6 respectively.ConclusionSystemic inflammation and S. haematobium infections are negatively associated with cognitive function. We recommend the inclusion of PSAC into mass drug treatment programs. more...

Mutemeri, Judith and Chetty, Rajendra
- Abstract
The purpose of the study was to examine university-school partnerships in the process of teacher education. The research question that guided the study was how teacher educators partner with schools in teacher training. A qualitative study was preferred because the aim was to gather information and opinions on how teacher educators trained student teachers as well as to provide a forum for pre-service student teachers to air their views about how they were trained. Twenty- six lecturers and nine student focus groups, purposively sampled, participated in the study. An interview was used for data collection and Holliday's thematic approach was used to analyse the data. The research revealed that there was a weak partnership between teacher education and schools. The study recommends the creation of third spaces in teacher education which involve an "equal and more dialectical relationship between academic and practitioner knowledge" in support of student teachers' learning. more...

There is a paucity of reference early childhood development (ECD) data at community level in rural Africa. Our objective was to conduct a comprehensive assessment of ECD in rural Zimbabwe and determine the impact of stunting and schistosome infections on ECD. Using the Griffiths Scales of Child Development, we conducted a cross sectional assessment of Eye and Hand Coordination (EHC), Personal-Social-Emotional (PSE), Language and Communication (LC), Foundations of Learning (FL) and Gross Motor (GM) domains and the summary General Development (GD) in 166 children aged 6–72 months. The effects of stunting, malnutrition and Schistosoma haematobium infection on ECD was determined. The impact of praziquantel curative treatment of schistosome infection on the developmental scores was determined through a longitudinal follow up at 6 and 12 months. From an initial 166 children, 11 were found to have developmental deficits warranting further investigation. Of the remaining 155, 58.7% recorded a good (≥ average) score for the overall General Development (GD). Proportions of children scoring above the cut-off (≥ average) for each domain were GM (84.5%), PSE (80.6%), EHC (61.9%), FL (43.9%) and LC (44.5%). The prevalence of stunting was 26.8% (95% CI = 20.1%–34.8%) Scores for stunted children were significantly lower for EHC (p = 0.0042), GM (p = 0.0099), and GD (p = 0.0014) with the fraction of lower scores attributable to stunting being GM = 63.4%, GD = 46.6%, EHC = 45%, and LC = 21%. S. haematobium infection prevalence was 39.7% and mean infection intensity was 5.4 eggs/10 ml urine. Infected children had poorer cognitive performance scores for the FL (p = 0.0005) with 30.8% of poor FL attributable to the infection. Performance in all domains improved to the expected normal or above reference levels at 6 and 12 months post curative treatment of schistosome infections. Our study documented reference values for ECD in rural Zimbabwean children. The study detected deficiencies in the FL domain, which were more pronounced in children, infected with schistosomes, highlighting the need for provision of cognitive stimulation tools and access to early childhood foundation education. There is also need for improved child nutrition and treatment of schistosome infections to improve child development outcomes. Author summary There is a paucity of comprehensive early childhood development data at community level in rural Africa. We assessed the development of rural Zimbabwean children aged 6–72 months and determined the impact of stunting and schistosome infections on their 5 developmental domains; Eye and Hand Coordination, Personal-Social-Emotional, Language and Communication, Foundations of Learning and Gross Motor domains and the summary General Development. We have demonstrated that just over 50% of Zimbabwean children in rural areas are on course for normal child development; with many being more advanced for their age in Gross Motor and Personal-Social-Emotional domains. We also demonstrate that the children face developmental challenges in early childhood, particularly in Foundations for Learning which represents critical psychometric constructs and cognitive skills for learning, executive function, ways of thinking, problem solving, organizing and information planning, analytic thought and memory. We further demonstrate that the poor development scores especially in Foundations for Learning were also attributable to stunting and schistosome infection, with the impact of the latter being reversed by curative antihelminthic treatment. Taken together, the findings strengthen the call for the treatment of paediatric schistosomiasis, accessibility to cognitive stimulation tools and improved nutrition to improve childhood health outcomes. more...

Africa’s vast mineral resources can play a transformative role when managed within the context of the continental blueprint for mining (AMV) and others including the ISG report on “Minerals and Africa’s Development”. It has been 12 years since the AMV was approved for implementation. One critical message from the ISG report and the AMV is to use the notion of linkages to change mining as an enclave activity to one integrated with the rest of the economy. Whilst this has not happened completely, some progress has been made. Besides, a lot has happened and is still happening. These include mining automation, energy transition and COVID-19 among others. One key global trend that will impact significantly on the mining sector is the energy transition; thus, Africa needs to position itself to take advantage of the opportunities, whilst mitigating the challenges. Furthermore, implementation of the AMV will only succeed when a supportive constituency is built by active engagement among governments, CSOs, the private sector and Research Think Tanks. more...

Summary Background Child stunting reduces survival and impairs neurodevelopment. We tested the independent and combined effects of improved water, sanitation, and hygiene (WASH), and improved infant and young child feeding (IYCF) on stunting and anaemia in in Zimbabwe. Methods We did a cluster-randomised, community-based, 2 × 2 factorial trial in two rural districts in Zimbabwe. Clusters were defined as the catchment area of between one and four village health workers employed by the Zimbabwe Ministry of Health and Child Care. Women were eligible for inclusion if they permanently lived in clusters and were confirmed pregnant. Clusters were randomly assigned (1:1:1:1) to standard of care (52 clusters), IYCF (20 g of a small-quantity lipid-based nutrient supplement per day from age 6 to 18 months plus complementary feeding counselling; 53 clusters), WASH (construction of a ventilated improved pit latrine, provision of two handwashing stations, liquid soap, chlorine, and play space plus hygiene counselling; 53 clusters), or IYCF plus WASH (53 clusters). A constrained randomisation technique was used to achieve balance across the groups for 14 variables related to geography, demography, water access, and community-level sanitation coverage. Masking of participants and fieldworkers was not possible. The primary outcomes were infant length-for-age Z score and haemoglobin concentrations at 18 months of age among children born to mothers who were HIV negative during pregnancy. These outcomes were analysed in the intention-to-treat population. We estimated the effects of the interventions by comparing the two IYCF groups with the two non-IYCF groups and the two WASH groups with the two non-WASH groups, except for outcomes that had an important statistical interaction between the interventions. This trial is registered with ClinicalTrials.gov, number NCT01824940. Findings Between Nov 22, 2012, and March 27, 2015, 5280 pregnant women were enrolled from 211 clusters. 3686 children born to HIV-negative mothers were assessed at age 18 months (884 in the standard of care group from 52 clusters, 893 in the IYCF group from 53 clusters, 918 in the WASH group from 53 clusters, and 991 in the IYCF plus WASH group from 51 clusters). In the IYCF intervention groups, the mean length-for-age Z score was 0·16 (95% CI 0·08–0·23) higher and the mean haemoglobin concentration was 2·03 g/L (1·28–2·79) higher than those in the non-IYCF intervention groups. The IYCF intervention reduced the number of stunted children from 620 (35%) of 1792 to 514 (27%) of 1879, and the number of children with anaemia from 245 (13·9%) of 1759 to 193 (10·5%) of 1845. The WASH intervention had no effect on either primary outcome. Neither intervention reduced the prevalence of diarrhoea at 12 or 18 months. No trial-related serious adverse events, and only three trial-related adverse events, were reported. Interpretation Household-level elementary WASH interventions implemented in rural areas in low-income countries are unlikely to reduce stunting or anaemia and might not reduce diarrhoea. Implementation of these WASH interventions in combination with IYCF interventions is unlikely to reduce stunting or anaemia more than implementation of IYCF alone.

Despite its importance for sustainable development, strategies for regulating artisanal and small-scale mining (ASM) in Africa are often maladapted to local contexts. In this article, we describe ASM’s dimensions in Africa and current regulatory frameworks, most of which are based on a “scaling-down” of large-scale mining regulations. We then argue that ASM policy should be reformed in two ways. First, it should become outcomes based, seeking to achieve such goals as the protection of natural resources, good health and safety standards, skills development, and access to legitimate channels for the processing and/or sale of minerals. In order to achieve particular outcomes, ASM policy will need to begin to regulate spaces rather than individual miners. Second, we argue that more inclusive approaches to policymaking are required: they must incorporate local miners’ associations and cooperatives and build their capacity in order to make ASM regulation effective. more...

- Abstract
The advancement and development of the financial sector is fundamental for building an efficient economic system that enhances foreign and domestic investments. The aim of this study was to compare the relationship between the price performance of initial public offerings and macroeconomic indicators in the South African and the Nigerian economy. With the increase of IPO listing on both stock exchanges, it is of paramount importance that an analysis and examination of IPO performance and its contribution to the economy is conducted. Using the 91 and 19 initial public offerings that were listed on the Johannesburg Stock Exchange and the Nigerian Stock Exchange respectively during the years 2005 to 2015, price performance was measured by using the market-adjusted abnormal returns and the wealth relative model. The linear ordinary least squares regression model was used to measure the relationship between initial public offering performance and macroeconomic indicators. Based on the mean market adjusted returns, initial public offerings listed between 2005 and 2015 were under-priced. The regression model established that the first day, week and month price changes in Nigeria were 0.19, 0.48 and 0.77 times higher respectively than to South Africa. The regression analysis found that inflation and interest rates were positively correlated with price changes at the end of the first month of trade, whereas gross domestic product growth was not statistically significant. Therefore, to evade financial loss, investment decision making processes should consider factors such as geographic location, interest rates, inflation and the industry prior to making the decision., Die bevordering en ontwikkeling van die finansiële sektor is fundamenteel vir die ontwikkeling van ʼn doeltreffende ekonomiese stelsel wat buitelandse en binnelandse investering aanmoedig. Die doel van hierdie studie was om die verhouding tussen die prysprestasie van aanvanklike openbare aanbiedinge en makro-ekonomiese aanwysers in die Suid-Afrikaanse en Nigeriese ekonomie te vergelyk. Met die toename in AOA-notering op albei aandelebeurse, is dit uiters belangrik dat ’n ontleding van en ondersoek na AOA-prestasie en sy bydrae tot die ekonomie uitgevoer word. Deur gebruikmaking van die 91 en 19 aanvanklike openbare aanbiedinge wat onderskeidelik op die Johannesburgse Effektebeurs en die Nigeriese Effektebeurs gedurende die tydperk 2005 tot 2015 genoteer is, is prysprestasie gemeet deur gebruikmaking van die markaangepaste abnormale opbrengste en die rykdomrelatiewe model. Die lineêre gewone kleinste kwadrate-regressiemodel is gebruik om die verwantskap tussen die prestasie van aanvanklike openbare aanbod en makro-ekonomiese aanwysers te meet. Op grond van die gemiddelde markaangepaste opbrengste was aanvanklike openbare aanbiedinge wat tussen 2005 en 2015 genoteer is, onderprys. Die regressiemodel het vasgestel dat die eerste dag-, week- en maandprysveranderinge in Nigerië onderskeidelik 0.19, 0.48 en 0.77 keer hoër as in Suid-Afrika was. Die regressieontleding het bevind dat inflasie en rentekoerse ’n positiewe korrelasie gehad het met prysveranderinge aan die einde van die eerste handelsmaand, terwyl bruto binnelandse produk se groei nie statisties beduidend was nie. Derhalwe, om finansiële verlies te ontduik, behoort investeringbesluitnemingsprosesse faktore soos geografiese ligging, rentekoerse, inflasie en die bedryf in aanmerking te neem voordat besluite geneem word., Ukuqhubekela phambili kanye nentuthuko yomkhakha (sector) yezezimali kubalulekile ekwakheni inqubo yezomnotho esebenza kahle neqhubekela phambili ukutshalwa kwezimali zangaphandle kanye nezangaphakathi ezweni. Inhloso yalolu cwaningo bekuwukuqhathanisa ubuhlobo phakathi kokusebenza kwentengo yama-initial public offerings kanye nezinkomba zama-macroeconomic kumnotho weNingizimu Afrika kanye nowase-Nigeria. Ngokwenyuka kwe-IPO listing kuwo womabili ama-stock exchange, kubaluleke kakhulu ukuthi kwenziwe uhlaziyo nohlolo lokusebenza kwe-IPO kanye nomthelela wakho kumnotho kumele kwenziwe. Ngokusebenzisa ama-initial public offerings ka 91 no 19 kwi-Johannesburg Stock Exchange kanye nakwi-Nigerian Stock Exchange ngokuhambisana phakathi kweminyaka ka 2005 kanye no 2015, ukusebenza kwamanani entengo kwakalwa ngokusebenzisa ama-market-adjusted abnormal returns kanye ne-wealth relative model. Imodeli ye-linear ordinary least squares regression model kwasetshenziswa ukukala ubuhlobo phakathi kwama-initial public offering performance kanye nezinkomba ze-macroeconomic. Ngokulandela i-mean market-adjusted returns, ama-initial public offerings okwafakelwa kuhla phakathi kweminyaka ka 2005 kanye no 2015 kwakufakelwe ngentengo ephansi. I-regression model yathola ukuthi ngosuku lokuqala, ngeviki, kanye nenyanga, ukushintsha kwamanani entengo eNigeria, kwakungu 0.19, 0.48 kanye ne 0.77 ngezihlandla eziphezulu kuneNingizimu Afrika. Uhlaziyo lwe-regression analysis lwathola ukuthi i-infleshini kanye namazinga enzalo achaphazeleka ngendlela enhle ngokuhambisana noshintsho lwentengo ekupheleni kwenyanga yokuqala yokuhwebelana, lapho khona ukukhula kwe-gross domestic project kwakungakhulile kakhulu ngokwezibalo. Ngakho-ke, ukugwema ulahlekelo kwezezimali, izinqubo zokuthatha izinqumo ngotshalo-mali kumele kubonelele izinto ezifana nendawo okuyi-geographical location, amazinga enzalo, i-infleshini kanye nemboni ngaphambi kokuthatha isinqumo. more...

- Abstract
The number of children diagnosed with autism around the world is increasing. Unlike a few years ago, more about the disorder is known today, which facilitates the improvement of outcomes of the many children diagnosed with the disorder. However, most of what is documented about autism today is based on research from the Western world. Limited research has been conducted about children with autism and their families in other parts of the world, particularly Africa. This current study was an attempt to address that concern. A purposive sample of five parents of children with autism in Zimbabwe were interviewed to explore their experiences in terms of getting their children diagnosed and access appropriate services. The results indicated that the parents viewed the process of diagnosis as difficult and at times inaccurate. The parents also identified several challenges including social stigma, strained family relationships, and lack of access to appropriate services. Based on results of this study it is recommended that parents and service providers of children with autism should be educated about child development and autism to promote efficient diagnoses. It is also recommended that service providers working with children with autism should collaborate with the parents in order to improve the treatment outcomes for the children. more...

A study on the influence of soil drainage and elephant damage on the abundance and structure of Colophospermum mopane was carried out in Central Mana Pools National Park (MPNP) Zimbabwe. Data were collected in April- May 2013. The stratified random sampling method was employed. The study area was stratified according to soil drainage. Three strata were established namely; well drained, moderately drained and poorly drained soils. Ten plots were sampled in each strata and a total of 30 plots were sampled to determine the abundance and structure of C. mopane in Central MPNP. Results from One way ANOVA showed significant differences in tree height, basal area, tree canopy volume, shrub canopy volume, sapling density, tree density, number of stems per tree and damaged trees density (PA‹Â‚0.05). There was no significant difference in the number of dead trees across the three strata (PA‹Âƒ0.05). Moderately drained soil had the highest number of undamaged trees (n=91; 42%), saplings and stems per tree. Well drained soils had the highest number of damaged live trees (n=112; 51%) and poorly drained soils had the highest number of dead trees (n=60; 51%). There were significant differences in damage (PA‹Â‚0.001). Regression analysis showed a negative relationship between elephant density and damaged trees density (R2=0.03; PA‹Âƒ0.05), however, there was a positive relationship between elephant density and dead trees (R2=0.3865; PA‹Â‚0.05). Results from this study suggest that soil properties as well as elephant damage have an influence on the abundance and structure of C. mopane, therefore the need for constant monitoring of this tree species. more...

The aim of the study was to establish the extent to which mathematics instructional practices in early childhood education relate to or make use of children's experiences. The major question that guided the study was: In which ways do early childhood teachers use children's out-of-school strategies and everyday experiences in teaching mathematics? The study was conceptualised within a constructivist framework, in which meaningful mathematics instruction for young learners capitalises on their prior knowledge and the ways they solve their daily mathematical problems, and promotes active thinking in the process of making meaning. The study was qualitative, involving classroom observations using videotapes, interviews with teachers and questionnaires with Grade 1 and 2 teachers in a district of Masvingo, Zimbabwe. The major findings of the study were: teachers used children's knowledge minimally when introducing lessons and failed to build on children's knowledge throughout the lessons. There were observably low motivation and low performance by children during lessons. The ramifications of the study for policy and practice are discussed. more...

Mining is an important part of the South African economy and has been the driver of much of the economic development of the country. However, the small–scale mining subsector still has to realise its full potential. A small–scale mine has been defined as a mining activity employing less than 50 people and with an annual turnover of less than 7.5 million Rand and includes artisanal mines. Small–scale miners are involved in many commodities but there appears to be a bias towards gold, diamonds and quarrying for construction materials, including brickclays. Small–scale mining is regulated by the same legislation (i.e., for the environment, labour, mineral rights, exploration and mining permitting, and skills development) as large–scale mining, though compliance is low, particularly where artisanal mining in concerned. The effective participation of small–scale miners in the mining sector is hampered by their lack of skills, i.e., technical, business and management, and their limited access to mineral deposits, capital and markets. Some of these hindrances have been inherited from the imbalances of the colonial and apartheid eras and continue to act as barriers, making entrance to the industry difficult. For those who have entered the industry out of desperation, as is the case with most artisanal miners, their activities result in negative impacts evident in the inefficient, unsafe and environmentally unfriendly operations. With the advent of the new political dispensation in South Africa, a new era is dawning for the country’s small–scale mining subsector. This has resulted in a change of attitude and new government policies which have led to special programmes being put in place to promote the subsector. Intervention strategies for the support of small–scale mining (some of which are already in operation) include programmes for kickstarting mineral beneficiation and value–addition projects, development of appropriate technologies and skills and technology transfer. Proponents of small–scale mining see a well–regulated industry as being the cornerstone of future rural economic development, particularly for previously disadvantaged communities in the poverty nodes. more...

This paper seeks to expose what innovative teaching there is in the Zimbabwean science-teaching context, as well as what opportunities and what challenges there are. Science is the mother of all technology hence no sustainable development can take place in any country without talking about science. Qualitative methodology was used where questionnaires, focus groups and observations were the main tools for this study. Triangulated data was analysed and results showed that from the time Zimbabwe attained independence in 1980, the government has put in place five innovative projects to improve the delivery of science teaching in schools, some of which are Zimbabwe Science Project, Quality Education in Science Teaching and the Science Education In-service Teacher Programme. Teachers are engaging students in hands on activities (Interactive Teaching Strategy), group work, seeding discussion while problem solving, demonstrations, questioning thus providing students with a multi - sensory learning experience. The challenges include brain drain of science teachers into industry and inadequate resources. We recommend that schools must offer the foundation for developing computer skills and knowledge and fund raise to alleviate the shortage of resources. more...

An economic evaluation methodology is proposed for assessing the returns to research and extension activities designed to increase household maize production and financial returns to smallholders. Multiple regression and least significant difference analysis of smallholder production data are combined to estimate economic returns to research and extension activities in selected high rainfall regions in Zimbabwe. Results indicate that economic returns are substantially higher for agronomic compared to varietal research and extension. more...

The purpose of the study was to examine university-school partnerships in the process of teacher education. The research question that guided the study was how teacher educators partner with schools in teacher training. A qualitative study was preferred because the aim was to gather information and opinions on how teacher educators trained student teachers as well as to provide a forum for pre-service student teachers to air their views about how they were trained. Twenty- six lecturers and nine student focus groups, purposively sampled, participated in the study. An interview was used for data collection and Holliday’s thematic approach was used to analyse the data. The research revealed that there was a weak partnership between teacher education and schools. The study recommends the creation of third spaces in teacher education which involve an “equal and more dialectical relationship between academic and practitioner knowledge” in support of student teachers’learning.Keywords: mentors; partnership; practice teaching; skills development; student teacher learning; third spaces more...

- Abstract
From the perspective of large-scale mining companies (LSM), the problems of artisan miners encroaching on their concessions include: security risks, safety and health impacts, knock-on environmental effects, and social impacts. The LSM are trying to find ways to manage the risk of artisan mining on their property as they are often held responsible for the effects caused by such miners. GIS-based monitoring is being carried out at the Geita mine in Tanzania, the area surrounding the Siguiri Ashanti mine in Guinea, and the Yatela and Sadiola mines in Mali. Monitoring is carried out using a preliminary remote-sensing survey, field-based data collection, and continuous monitoring on the ground. This is a cost-effective method which will provide valuable information for corporate decision-making and for intervention focussing on the education of locals and the development of local governance structures to mitigate the impact of artisan mining., From the perspective of large-scale mining companies (LSM), the problems of artisan miners encroaching on their concessions include: security risks, safety and health impacts, knock-on environmental effects, and social impacts.

Energy Policy - Abstract
This thesis focuses on issues surrounding energy regulation, and specifically regulation of pipelines that carry petroleum products in South Africa. The introduction of a regulator for petroleum pipelines is part of an ongoing process taking center stage in the South African government's petroleum industry policy arena. Independent regulation of energy industries is a recent phenomenon in South Africa. There is much activity in deciding which regulatory models should be adopted in the energy sector. The thesis analyses a government policy decision to introduce a regulator of petroleum pipelines. Among some of the key issues that receive attention are the following: • Is the petroleum pipeline industry in South Africa large enough to justify an independent regulator? • Do pipelines in South Africa enjoy monopoly rents? If they do, is the establishment of an independent regulator the most cost-effective way of dealing with monopoly rents? • How effective would such a regulator be in the current structure of the country's petroleum industry? Road and rail transport systems carry vast quantities of petroleum products. Would it be more appropriate for the regulator to include all transporters of petroleum products? The thesis concludes that for an industry of such small size as pipeline transportation in South Africa, the necessity of a pipeline regulator might need to be reviewed. For a variety of reasons, there are strong reasons to conclude that a pipeline regulator will have minimum impact over key issues of the transportation of petroleum products. more...

Mining industry ,Economic development -- South Africa ,Business, international - Abstract
While South Africa is respected in the mining fraternity for its seemingly prosperous large-scale mining industry; its artisanal and small-scale mining (ASM) sector is characterised by informal and illegal activities with limited prospects for growth and contribution to socio-economic development. This paper examines through literature review, the institutional frameworks e.g. policy, legislation and programmes put in place to facilitate the development of the ASM sector in order to identify the gaps and challenges in the ASM sector. The recognition of the ASM sector in 1994 came with a series of frameworks aimed at supporting the development of the sector. This paper finds that while the main legislative framework broadly supports a transformation agenda as it pertains to ASM (e.g. increasing the participation of disadvantaged South Africans) there is considerable criticism on the requirements of the framework which are argued to have hindered the development of the sector. In line with the current wave of discussions on policy and legislation reforms in the mining and minerals sector in Africa; it is recommended that South Africa as a signatory to the African Mining Vision (AMV), should consider the domestication of the AMV which would result in the development of appropriate support frameworks for the ASM sector to enable it to contribute to the South African economy., https://www.sciencedirect.com/science/article/pii/S0301420717303446 more...

IMPERIALISM , *CRITICAL pedagogy , *EDUCATIONAL ideologies - Abstract
The aim of the paper is to illuminate the underlining reasons for the binary conceptualization of school knowledge and everyday knowledge. The historical and philosophical lens will be used as analytical tools for this discussion. The main argument of this paper is that the binary conceptualization of school knowledge and everyday knowledge is a social construct with latent functions where the colonizer's aim was to unfit the colonized for their habitation in order to maintain dependence and therefore ensure a continued supply of labour for their business establishments. Using Critical Pedagogy Theory that links education with the analysis of politics and economy; the paper also provides theoretical analysis on how learners and teachers are subjected to and are subjects of schooling in an effort to show how the binary conceptualization of school knowledge and everyday knowledge have been sustained and maintained. Last, the paper suggests Shor's and Freire's (1987) situated pedagogy which uses learner's everyday knowledge as foundation for the acquisition of school knowledge, and looks at the implication of the duality of the conceptualization of school knowledge and everyday knowledge for teacher education for readers introspection.

- Abstract
Of the gold-bearing rock types found in the Venus shear zone, only the most common, biotite-actinolite schists and banded felsites, have so far been studied in detail. Microthermometric and compositional data indicate trapping of similar fluids over a wide range of pressure and temperature conditions, suggesting that the shear zone was active for an extended period of time but that fluid fluxes varied little. Differences between trapping temperatures and pressures for barren and mineralised samples of both lithologies are slight enough to indicate that the amount of gold was more dependent on the quantity than the type of fluid passing through., Of the gold-bearing rock types found in the Venus shear zone, only the most common, biotite-actinolite schists and banded felsites, have so far been studied in detail.
