The Challenges of Implementing a Health Referral System in South Africa: A Qualitative Study.

Health system strengthening efforts also entails streamlining an existing referral system in a particular context to improve quality of health care offered to people. Conceptually, the referral system in South Africa, is seemingly sound. Nevertheless, gaps exist in its implementation. The aim of this study was toexplorehealth care professionals' perceptions of referral system implementation in the Buffalo City Metropolitan Municipality (BCMM) in the Eastern Cape Province of South Africa. This qualitative study included 12 health care professionals as participants. Each participant was interviewed using a semi-structured interview guide; with their consent, the interviews were audio recorded andtranscribed verbatim. For data analysis, a thematic content analysis was used. The participants identified many impediments to the effective implementation of the referral system in BCCM. The main obstacles were deteriorating infrastructure, inadequate staffing, lack of transportation, and inadequate medical supplies and medications. In mitigation, the participants proposed suggestions such as increasing the capacity of the health workforce, allocating personnel appropriately, increasing the availability of transportation, and providing essential medications to all levels of care. They also suggested involving all stakeholders in the referral process, providing education and training to health professionals on the referral system, and enhancing communication and feedback between the various levels of care. These challenges emphasised in this study highlight the need for targeted interventions to improve the referral system in this setting.

Enriching Professional Development in Disadvantaged Schools through the Targeting Talent Programme (TPP) Educators Enrichment Programme: Insights from Math and Science Educators

This study explores the lived experiences of educators from disadvantaged schools involved in professional development in the Targeting Talent Programme (TPP) at the University of the Witwatersrand. It elicits the perceptions of mathematics and science educators on professional development programmes. A qualitative research approach was employed, and data was collected through focus group discussions with 24 participants comprising Math and Science educators. The study’s findings indicated that acquiring the requisite knowledge and skills from participating in the programme improved the understanding of pedagogical content, skills and teaching methodologies. The major barrier besetting the realisation of educators’ professional development identified included the public-school system in South Africa characterised by resource constraints which limit educators’ innovative strategies in integrating technology into teaching and learning. The study revealed that reflection is required regarding the rules and policies regulating learners’ and educators’ use of technological gadgets. From the findings, it is recommended that designing and implementing educator professional development must be embodied within South African school policies.

Analysis of the translation strategies used for non-equivalent Grade 4 geography concepts

Adoption of a multilingual educational system in South Africa necessitates translation services, as the diverse official languages that are spoken in South Africa and their attendant cultures rarely have conceptual equivalents. The paucity of conceptual equivalents in natural sciences like geography calls for strategies on how to equate concepts ideologically and semantically between languages such as English and Tshivenḓa. Hence, this article analyses the translation strategies applied when translating Grade 4 geography concepts from English into Tshivenḓa. A qualitative phenomenology inquiry is used. The data were examined using inductive thematic analysis. Skopos and the Scan and Balance theories served as the theoretical framework. It was found that the translators used paraphrasing, more general words, related words, transliteration and omission as strategies to attain equivalence. This article provides translators with relevant and applicable translation strategies to address the non-equivalence between English and Tshivenḓa Grade 4 geography terminologies. It prompts the Department of Education to implement the Language-in-Education Policy and translate subjects such as Grade 4 geography from English into Tshivenḓa by demonstrating the feasibility of the suggested translation strategies. The findings may also contribute to the development of Tshivenḓa, one of South Africa’s minority languages.

Morphological and Chemical Characteristics of Microplastics in Surface Water of the Vaal River, South Africa

Microplastics research in South Africa has focused on marine and coastal areas, with limited studies reporting microplastics in freshwaters. To address this gap, we conducted this study to investigate the presence, abundance, physical characteristics, and chemical composition of microplastics in the surface water of the Vaal River, one of the most important freshwater systems in South Africa. Twenty-two surface water samples were collected along 60 km of the middle part of the river using a 55 μm plankton net. Samples were treated by acid digestion, and MPs were separated by density separation. Physical identification was performed using a Nikon stereomicroscope, and chemical composition was identified using Raman spectroscopy. MPs were observed in all samples with 0.13 to 2.52 particles/m3 concentrations. Microplastics ranged in size from 0.06 – 4.95 mm, with more than 89% less than 2 mm, and 81% were fragments (39%) and fibers (42%). Microplastics were observed in numerous colours, of which green, black, and blue were the most dominant, representing 22%, 19%, and 18%, respectively. Chemical analysis revealed the polymer types as high-density polyethylene (HDPE), polypropylene (PP), and low-density polyethylene (LDPE). In addition, two colourants, pigment yellow 83 and carbon black, were detected. This study provides new data on microplastic occurrence and characteristics in the Vaal River system and offers a baseline for future monitoring. Our findings confirm that the Vaal River is under a real threat of microplastic contamination, which could impact its role as a significant freshwater system in South Africa.Highlights• Microplastics were prevalent in the surface water of the Vaal River.• Fibrous, small-sized, and coloured microplastics were most abundant.• Polymers were identified as HDPE, LDPE, and PP.

Gastropod invasions in anthropogenically impacted impoundments in South Africa: Tracing their origins and exploring field evidence of parasite spillback and amplification

Invasive snails are associated with ecological problems in freshwater bodies worldwide. However, their impact on the transmission of digenean infections remain underreported. In the present study, 1708 specimens representing four snail species were sampled from four impoundments in the Limpopo River system in South Africa. Gyraulus chinensis (Planorbidae), Physella acuta (Physidae) and Pseudosuccinea columella (Lymnaeidae), which are invasive, were found in all the sampling sites. In contrast, the native lymnaeid Radix natalensis occurred at only one study site. Digeneans were observed only from R. natalensis (prevalence = 49%) and Ps. columella (prevalence = 23%). Morphological and genetic analyses revealed four digeneans: Fasciola nyanzae, Orientocreadium sp., Petasiger sp. and Patagifer vioscai. Pseudosuccinea columella was infected by the four digeneans while R. natalensis harboured only Orientocreadium sp. and Petasiger sp. Partial sequences of Orientocreadium sp. from the current study differed from congeners whose DNA data are available on GenBank, by p-distances of at least 1.84 and 2.2% for 28S and the internal transcribed spacer (ITS) rDNA, respectively. Phylogenetic analyses demonstrated that the present species is sister to Orientocreadium batrachoides. Genetic and phylogenetic data based on 28S and ITS rDNA suggested that Petasiger sp. from the present study and isolates of three unidentified Petasiger spp. from Kenya, Hungary and Australia, were representatives of the same species. This is the first known report of Orientocreadium, Petasiger and Patagifer from Ps. columella. The occurrence of F. nyanzae in Ps. columella indicates spillback from R. natalensis. These findings echo the concerns raised in previous studies about the potential role of Ps. columella in the amplification of digenean diseases in its introduced range. Phylogenetic analyses of partial sequences of the cytochrome c oxidase subunit 1 mitochondrial gene (cox1) showed multiple lineages of Ps. columella in North and South America. Pseudosuccinea columella specimens from the present study belong to an invasive genotype that has spread globally and has been reported from Zimbabwe, Egypt, Portugal, Australia, Argentina, Colombia and New Mexico (USA). Physella acuta from the current study had a stronger genetic relationship with isolates from Canada and Iceland, than with isolates from other parts of Africa, suggesting several invasion routes into Africa. This is the first known DNA characterisation of G. chinensis from Africa. Phylogenetic reconstruction indicated multiple exit events of G. chinensis from Asia into Europe and Africa. South African isolates clustered in a recent branch containing isolates from the Czech Republic and Hong Kong, China. Considering the presence of invasive snails in all the sampling sites in the present study, it is necessary to investigate the factors that enhance their establishment and to monitor their effects on the native snail populations.

A carbon footprint assessment for pasture-based dairy farming systems in South Africa

Environmental impact evaluation of intensive dairy farming systems has been of growing interest recently as agriculture has several negative influences on the surrounding environment, including eutrophication, declines in biodiversity, and pollution of nearby waterbodies. Dairy production in particular is characterized by the emission of greenhouse gasses (GHG) contributing toward climate change. In this study, the carbon footprint of South African pasture-based dairy farming systems was assessed using a farm-gate life-cycle assessment (LCA) approach. A total of 82 pasture-based dairy farms across South Africa were assessed (2012–2022). The average carbon footprint across all dairy farming systems was 1.36 ± 0.21 kg CO2eq kg−1 fat- and protein-corrected milk produced (FPCM), which is higher than similar studies performed outside South Africa. Enteric fermentation had the largest influence on the carbon footprint, indicating the key role of methane as an emission source in ruminant dominated livestock systems. A difference in milk production efficiency was found between farming systems with the lowest and highest carbon footprints. Pasture-based dairy farming systems must be managed with adaptive management such as regenerative agriculture. Future research agendas should explore modeling approaches to assess the economic and environmental impact of dairy production, formulating a holistic understanding of the system dynamics while also quantifying net carbon emissions or sinks.

Data-Driven Strategies for Addressing Challenges in Teacher Placement: A Legal and Pedagogical Analysis for Inclusive Education in South Africa

Teacher placement is a major challenge in South Africa, with limited school placements available for student teachers. This conceptual research studied how data-driven strategies may be used to tackle this problem, with a focus on legal and pedagogical problems to promote inclusive education. The article proposed that the use of data analytics may improve evidence-based decision-making in teacher placement. It focussed on providing equal access to education for all learners. Based on a review of relevant literature and legal frameworks, as well as insights from pedagogical practices and data analytics in education, this study proposed three major concepts for harnessing data-driven techniques to address teacher placement difficulties. The article first stated that an inclusive approach to data collection and analysis can improve equitable access to education, particularly for historically disadvantaged learners. Second, the article emphasized the importance of data privacy and security in the collection and utilization of educational data. Finally, the article underlined the need for ongoing professional development as well as the support of teacher education programs in using data analytics to inform their practice. In general, this article argues that data-driven teacher placement strategies can assist in enhancing efficiency and effectiveness while also addressing socioeconomic inequities and encouraging inclusive education. The article concluded by stating that a more holistic approach to teacher placement that takes into account legal and pedagogical difficulties, as well as data-driven efforts, can lead to more egalitarian and effective education systems in South Africa. Overall, this study adds to the growing body of literature on data-driven education methods and offers a unique perspective on teacher placement in South Africa. Keywords: Teacher Placement, Data Analytics, Inclusive Education, South Africa, Legal Framework.

The Education Component and the Inclusion of the Enrolment Survival Measure: Provincial Equitable Share (PES)

This paper investigates the intergovernmental transfer systems in South Africa, more specifically, the underlying determinants and formula of the unconditional grants of the education component of the Provincial Equitable Share (PES). The PES formula is a weighted shares formula that depends on the demographic shares of the provinces (population) to determine the equitable share outcomes to be transferred to individual provinces. We find that the variables used have two main weaknesses: Firstly, the enrolment variable, which could be contaminated with school repeats and dropouts, is too broad to be an effective measure for representing the real beneficiaries of the transfers. Secondly, infrequent updates about the school-age cohort population variables render the desired PES grant transfers for education outdated as well as serially inconsistent. The paper also provides an analysis of the PES formula’s mathematical construct, followed by a few suggested variables to improve the relevance and accuracy of the formula of the revenue transfer. One such improvement is demonstrated by the inclusion of the Enrolment Survival Measure (ESR). More research and data are required to extrapolate nuanced results and to understand the socio-economic impacts of adopting these new variables in the PES formula going forward.

Human activity affects the quality of potable water sources and their associated bacterial communities. Here, we discuss the heterotrophic Bacillus altitudinis 2R-9 draft isolated from the raw source of a drinking water distribution system in South Africa.

Improving last mile distribution systems through the Internet of Things: a South African case

The study investigates the impact of the IoT on the cost and quality of last-mile logistics, the critical and often challenging final phase of the supply chain. With the relentless growth of e-commerce and the increasing demands for efficient and reliable delivery services, understanding how IoT affects last-mile logistics is increasingly becoming important. Through the integration of IoT technologies such as GPS tracking, RFID systems, and real-time data analytics, the study aimed to assess the extent to which the application of the IoT affects the cost and quality of last-mile distribution in South Africa. As a result, the study provides valuable insights into the potential cost savings or increases associated with IoT adoption, quality challenges and areas of improvement, customer satisfaction and the overall performance of last-mile distribution systems. The methodology involves the collection of primary data from selected distribution companies in South Africa. Statistical software was used to analyse the data to shed light on the tangible benefits and challenges associated with IoT adoption in last-mile logistics as they relate to cost and quality. The research findings indicate that implementing IoT in last-mile distribution systems in South Africa can significantly improve efficiency and effectiveness. The IoT integration with existing infrastructure enables seamless communication, proactive decision-making, and reduced delivery delays. Overall, by leveraging IoT technologies and real-time data analysis, organisations can optimise their distribution processes, reduce costs, improve quality, and enhance overall customer experience.

Assessing the imperative for school social workers: insights from principals and circuit managers in Mankweng circuit, South Africa

This research study investigated the critical role of school social workers within the educational landscape of Mankweng Circuit, South Africa. School social workers play a pivotal role in addressing the multifaceted challenges faced by students, their families, and school communities. Through a qualitative research approach, we conducted in-depth interviews with principals and circuit managers to explore their perspectives on the role of school social workers in promoting holistic student development, improving school climate, and addressing socio-emotional barriers to learning. The findings uncover the multifaceted challenges faced by school social workers, including limited resources, high caseloads, and the need for ongoing professional development. The implications of this research are significant, shedding light on the critical need for recognising and investing in the roles of school social workers in South African education. The insights gained from this study can inform policymakers, educators, and stakeholders in the field of education on the imperative of integrating school social workers into the educational system as vital contributors to the overall success and well-being of students. Ultimately, this research contributes to the ongoing discourse on strengthening the educational support system in South Africa and beyond.

Transitional community adherence support for people leaving incarceration in South Africa: a pragmatic, open-label, randomised controlled trial

People released from correctional facilities face multifactorial barriers to continuing HIV treatment. We hypothesised that barriers faced in the first 6 months of community re-entry would be decreased by a multilevel group-based and peer-led intervention, the Transitional Community Adherence Club (TCAC). We did a pragmatic, open-label, individually randomised controlled trial in five correctional facilities in Gauteng, South Africa. Participants aged 18 years and older and receiving antiretroviral therapy (ART) in correctional facilities were enrolled before release and randomly assigned (1:2) to either passive referral (usual care) or TCACs. TCACs followed a 12-session curriculum over 6 months and were facilitated by trained peer and social workers. Participants were followed up by telephone and in person to assess the primary outcome: post-release enrolment in HIV treatment services at 6 months from the date of release. We did an intention-to-treat analysis to determine the effectiveness of TCACs compared with usual care. The trial was registered with the South African National Clinical Trials Register (DOH-27-0419-605) and ClinicalTrials.gov (NCT03340428). This study is completed and is listed as such on ClinicalTrials.gov. From March 1, to Dec 13, 2019, we screened 222 individuals and enrolled 176 participants who were randomly assigned 1:2 to the usual care group (n=59) or TCACs (n=117). 175 participants were included in the final analysis. In the usual care group, 21 (36%) of 59 participants had enrolled in HIV treatment services at 6 months, compared with 71 (61%) of 116 in the TCAC group (risk ratio 1·7, 95% CI 1·2-2·5; p=0·0010). No adverse events were reported. We found strong evidence that a differentiated service delivery model with curriculum and peer support designed specifically to address the needs of people with HIV returning from incarceration improved the primary outcome of enrolment in HIV treatment services. Our approach is a reasonable model to build further HIV treatment continuity interventions for individuals in the criminal justice system in South Africa and elsewhere.

Reproductive compatibility of a newly imported Australian population of the biocontrol agent Anaphes nitens with an existing South African population

Introductions of natural enemies in classical biocontrol programs potentially cause genetic bottlenecks which can be detrimental for biocontrol. This can be mitigated by introducing multiple populations of a natural enemy, but thorough pre-release testing is needed to ensure compatibility. In this study compatibility between an established population of Anaphes nitens in South Africa and a newly imported A. nitens population from Australia was tested. Anaphes nitens is an egg parasitoid of Gonipterus sp. n. 2, an important pest in Eucalyptus plantations. South African and Australian A. nitens lineages were compared to two admixed lineages, which were reared from the F0 to the F2 generation. No differences were found in the proportion of replicates producing offspring overall, or female offspring specifically, indicating there was no sexual isolation between the populations. The typical symptoms of cytoplasmic incompatibility in haplodiploids, namely male biased sex ratios, were not observed. The lack of significant differences in fecundity and development time between the lineages suggested that there was no hybrid vigour or outbreeding depression. We conclude that a field release of the imported A. nitens population poses a low risk of disrupting the existing biocontrol program due to reproductive barriers or outbreeding depression. Whether there is a benefit of adding the newly imported Australian A. nitens population to the existing biocontrol system in South Africa needs to be studied further, for example by performing a field release combined with post-release assessments for determining establishment and spread.

Co-learning in university-community engagement for sustainable local food systems in South Africa

The legacy of racial and spatial segregation in South Africa has left an epistemic chasm between knowledge-producing institutions and members of disadvantaged communities most in need of applying scientific knowledge to address their local societal challenges. The aim of this study is to examine how the co-learning approach can be used to bridge the knowledge asymmetry between university researchers and communities within which their institutions are embedded by building bonds of mutual trust and involving target knowledge users in the design and testing of technological solutions targeted to their needs. Using the outcome mapping (OM) analysis of project documents and key informant interviews of participants in the co-learning project between the University of Johannesburg and Soweto smallholder farmers, this study illustrates the contribution of the co-learning approach to shaping networks of successful innovation co-creation. Our findings indicate that co-learning leads to the optimisation of the capacity building speed when co-learning partners have a shared commitment to the outcomes and application of the co-created knowledge.

THE UNDERSTANDING OF LEARNER INTEGRATION IN A SELECTED EX-MODEL C SCHOOL

Learner integration has become an asset for the meaningful resettlement of learners from different backgrounds in a one learning environment. Psychologically, the learner integration phenomenon is a crucial component in a teaching and learning context because it is linked to psycho-socio elements for the learners’ well-being. This study aimed to explore the understanding of learner integration in an Ex-Model C school. This paper identified the central elements of the diverse perceptions constituting successful learner integration in an Ex-Model C school. Moreover, the key traits in the understanding of learner integration were presented about the three overall themes that emerged from the findings of the study. The study was conceptualised within the Critical Emancipatory Research (CER) theoretical framework. The participants and research site were selected using purposive and convenience sampling. Data were generated through photovoice and multi-stakeholder meetings. Based on the South African historical background, this study maintains that learner integration has a transformative agenda as the phenomenon leans towards the democracy, social justice, and emancipation of education practices that are negatively affected by the inherent issues from the previous education system in South Africa. This implies that effective learner integration plays an essential part in ensuring equity, equality, and democracy in South African schools specifically Ex-Model C schools.

7 A Comparison of Performance of Educationally Disadvantaged Non-English-Speaking Participants on a Category Verbal Fluency Test using English or the First Language

Objective:South Africa has a multi-lingual population where fewer than 10% of the population speak English as a first language. This poses a challenge regarding language usage for a verbal fluency task. This study investigated the difference in number of words produced by independent groups of non-English examinees required to produce words in English, or in their first language, on a category verbal fluency task.Participants and Methods:A study on South African non-English first language participants was conducted using the Category Verbal Fluency test (animals) for a sample of nonclinical adults (N = 264) aged 18-60 years with 8-12 years of disadvantaged (poorly resourced) quality of education. Participants either had an African indigenous first language, or Afrikaans (a Dutch derivative) as a first language. The data were derived from one group of either African indigenous or Afrikaans first language participants who were required to use English for word production (Group A English) (n = 159; African indigenous n = 135; Afrikaans n = 24) and another group of participants who were required to use their first language (Group B First Language) (n = 105; African indigenous n = 83; Afrikaans n = 22). The comparative data were stratified for age ranges 18-20, 21-30, 31-40, 41-50 and 51-60 years. Level of education was broadly equivalent across the comparative groups. T-test analyses compared the number of words produced between the English versus indigenous African groups, and English versus Afrikaans first language groups for each age category.Results:The comparison for the indigenous African first language participants, revealed no significant differences in word production for words produced in English or first language regardless of age. In the comparison for the Afrikaans first language participants there was a highly consistent tendency for better word production in Afrikaans than in English. These results indicate that socio-cultural factors may be influential for English language proficiency on a verbal fluency task, rather than the effect of first language usage “per se”.Conclusions:Since the dismantling of the Apartheid system in South Africa thirty years ago, English has become the main language used in government and business and is the preferred language of tuition in schools for those speaking English or an African indigenous language, whereas during the Apartheid era, two official languages were used for government, business, and schooling (Afrikaans and English). Currently, many Afrikaans speaking individuals continue to have Afrikaans as the preferred primary language of tuition in the schools and it persists as the preferred language for use in many Afrikaans dominated business arenas. This study attests to a high level of English fluency amongst those South Africans with an indigenous African first language, who clearly are as fluent in word production using English as they are when using their first language, in contrast to the indications for Afrikaans speaking individuals. Practitioners need to be alert to sociocultural factors that can impact on the optimal use of language in test situations, which may not necessarily be the first language.

COVID-19: An evaluation of predictive scoring systems in South Africa

Background| The Coronavirus Disease 2019 (COVID-19) pandemic, caused by SARS-CoV-2, has resulted in more than 700 million cases worldwide. Sepsis and pneumonia severity scores assist in risk assessment of critical outcomes in patients with COVID-19. This allows healthcare workers to triage patients, by using clinical parameters and limited special investigations, thus offering the most appropriate level of care. Methods| A retrospective cohort study of 605 adult patients hospitalised with moderate to severe COVID-19, at a tertiary state hospital in South Africa. Evaluating the utility of the CURB65, NEWS2 and ISARIC-4C Mortality Score, in predicting critical outcomes, using clinical characteristics on admission. Outcomes included in-hospital mortality, invasive mechanical ventilation, and intensive care unit admission (ICU). Performance of severity scores and risk factors was assessed by area under the receiver operator characteristics (AUROC) analysis and logistic regression. Findings |A total of 605 records were used, 129 (21 %) non-survivors, 101 (17 %) ICU admissions and 77 (13 %) requiring invasive ventilation. Greater odds of mortality was associated with moderate and severe risk groups of the CURB65, ISARIC-4C and NEWS2 score. Mortality AUROC curve analysis for the CURB65 score was 0·76 (95 % CI: 0·71–0·8), 0·77 (95 % CI: 0·73–0·81) for the ISARIC-4C and 0·77 (95 % CI: 0·73–0·82) for the NEWS2 score. The CURB65 score had a sensitivity of 86 % with 12·8 % mortality, ISARIC-4C score a sensitivity of 87·6 % with 8 % mortality and NEWS2 score a sensitivity of 92·2 % with 8·6 % mortality. Interpretation |In 605 hospitalised patients with moderate to severe COVID-19, predominantly infected by the ancestral strain, good performance of the NEWS2 and ISARIC-4C score in predicting in-hospital mortality was noted. The CURB65 score had a high mortality rate in its low-risk group suggesting unexplained risk factors, not accounted for in the score, thus limiting its utility in the South African setting.

A Critical View On Doctoral Supervisor Capacity Development At A South African University Of Technology

Growing the number of doctoral graduates, increasing the capacity for study supervision, and enhancing the quality of research output and impact remain some of the many challenges for higher education institutions in South Africa – especially for universities of technology (UoTs). Study supervisors at UoTs often lack sufficient experience and capacity to guide doctoral students to timely and successful completion. This article explores one such case as an example of critically assessing the capacity, quality, and effectiveness of supervisory development at a UoT. Our valuational stance involves observing aspects of institutional support to grow supervision capacity, comparing research performance to peer universities in the UoT cluster and engaging the South African university system as related to relevant literature on doctoral supervision and graduation. The selected institutional case revealed that supervisory capacity and subsequent graduations have improved significantly over time. However, the challenge remains to graduate increasing numbers of doctoral students, hence the need for further enhancing supervisory capacity. The inquiry also points to the need for increasing throughput figures and graduation in meeting institutional targets. The UoT under scrutiny had introduced several strategies to capacitate doctoral supervisors, including promoting relevant supervisory skills, scientific writing and communication. It also promoted research dissemination, incentives to support research capacity development, and policies to enhance quality supervision. Since the range and scope of developmental actions and activities at the selected UoT were too broad to evaluate in one project, the focus was on one aspect of supervisor support, namely an institution-wide postgraduate supervision developmental programme. Programme results for the period 2017 to 2021 were critically evaluated, addressing two key dimensions: enhancing doctoral supervision capacity and trends in doctoral graduations. These dimensions are discussed against the background of relevant literature on supervisory capacity, peer UoT cluster trends in South Africa, as well as trends related to the whole public university system in South Africa. The article concludes with important lessons learnt from the institutional case and suggestions to enhance research into doctoral supervisor developmental interventions within an UoT context.
