Understanding the local implications of climate change: Unpacking the experiences of smallholder farmers in Thulamela Municipality, Vhembe District, Limpopo Province, South Africa

Climate change is experienced locally. However, climate change impact assessments are often done at the international, regional and national levels. Local level impacts are less prolific. When international, regional and national level predictions are applied to the local level, they are out of context. Therefore, it is important to understand the local impact of climate change to enhance formulation of suitable adaptation strategies. This study aimed to understand the local impacts of climate change on smallholder farmers in Thulamela Municipality, Vhembe District, Limpopo Province, South Africa. The actual experiences of smallholder farmers were unpacked. Face-to-face interviews with farmers in the region were conducted to solicit data on the climatic changes experienced, the impacts on crop and livestock production and social wellbeing. Data on the intensity of the impacts was also solicited. Results show that the experienced climatic changes emanated from temperature changes and shifts in rainfall patterns. The impacts on crop and livestock production as well as social wellbeing are all negative. Farmers indicated that the impacts were mostly average to high. It is concluded that smallholder farmers are aware that climate change impacts are negatively affecting their livelihoods. Investments towards building the capacity of smallholder farmers are pertinent.

Devastating effects of gender inequality on female students in South African higher education

Gender inequality is a concept of much relevance and is continuously gaining momentum. The diversification of different genders is pivotal to be able to address the effects of gender inequality. Globally, gender inequality has attracted a lot of interest and has huge effects on the social, academic and psychological. Although there is a nurturing environment for gender inequality, it is important to neutralize the playing fields for all genders to avoid negative effects on the victims of this phenomenon. The aim of this paper is to investigate the effects of gender inequality on South Africa’s higher education Students. It further seeks to challenge the perception contributing to gender inequality. Gender inequality is a universal problem affecting students throughout institutions of higher learning. The study used the qualitative research approach with exploratory research design adopted for the paper. The paper explored the effects of gender inequality on students from higher education institutions in South Africa. A sample of 15 students from institutions of higher learning who have been exposed to gender inequality was chosen for data collection process. A semi-structured face to face interviews was used during the data collection process with purposive sampling used to select participants to the study. The study used thematic content analysis to analyze data. The study applied feminist theoretical framework to understand the effects of gender inequality.

Enhancing education: the role and perceptions of assistant teachers in South African secondary schools

The concept of Assistant Teachers is new in South Africa. This concept was brought to South Africa during the COVID-19 pandemic. The introduction of assistant teachers in South Africa was an intervention in teaching and learning and in curbing youth unemployment. The assistant teachers are viewed as strangers in a school setting. Teachers and learners need to figure out their roles. South African teachers need assistance in classrooms to provide high standards of education. Using a qualitative research method, the study investigated the perceptions of principals, teachers, and learners of assistant teachers in secondary schools at Maleboho Central Circuit, Capricorn District, in Limpopo Province. The study used purposive sampling as a non-probability sampling technique procedure to select participants. The study sample comprised six learners, six teachers and three principals from three schools. Data were collected through interviews and document analysis. Collected data were analysed thematically. The study found that the presence of assistant teachers in a classroom has been documented as an asset to teachers. The assistant teachers play essential roles in the school. They manage and provide their skills in different departments of the school. Assistant teachers also learn and develop themselves into productive members of the school. Assistant teachers seemed to increase learners' enthusiasm for their academics. The study may assist the Department of Basic Education in providing the necessary support for having assistant teachers in respective schools.

Integrating hypertension detection and management in HIV care in South Africa: protocol for a stepped-wedged cluster randomized effectiveness-implementation hybrid trial

BackgroundHIV clinical guidelines recommend hypertension detection and management to lower cardiovascular disease risk, but these have not been effectively implemented for people living with HIV (PWH). Addressing this implementation gap requires community-engaged implementation studies focused on addressing implementation barriers specific to the HIV care context.MethodsThis protocol describes a type 2 effectiveness-implementation hybrid study conducted in nine primary care clinics in Johannesburg. The study will evaluate the effect of implementation strategies on guideline-recommended blood pressure assessment and management in HIV clinics and the effects of assessment/management on patient blood pressure. A stepped-wedge, cluster randomized study design was used to randomize clinics to the time at which they receive the implementation strategies and patient intervention. The implementation strategies tested include identifying and preparing care champions, changing record systems, conducting ongoing training, providing audit and feedback, and changing the physical structure/equipment. The patient intervention tested includes detection of elevated blood pressure, educational materials, lifestyle modification advice, and medication where needed. Implementation outcomes include adoption, fidelity (co-primary outcome), cost, and maintenance of the blood pressure assessment protocol in participating clinics, while patient outcomes include reach, effectiveness (co-primary outcome), and long-term effects of the intervention on patient blood pressure. These will be assessed via direct observation, study records, staff logs, medical chart reviews, and patient and healthcare worker surveys. To examine effects on the implementation (intervention fidelity) and effectiveness (patient blood pressure changes) co-primary outcomes, we will use the standard Hussey and Hughes model for analysis of stepped-wedge designs which includes fixed effects for both interventions and time periods, and a random effect for sites. Finally, we will examine the costs for the implementation strategies, healthcare worker time, and patient-facing intervention materials, as well as the cost-effectiveness and cost-utility of the intervention using study records, patient surveys, and a time and motion assessment.DiscussionThis study will address knowledge gaps around implementation of cardiovascular disease preventive practices in HIV care in South Africa. In doing so, it will provide a dual opportunity to promote evidence-based care in the South African HIV care context and help refine implementation research methods to better serve HIV populations globally.Trial registrationClinicalTrials.gov: NCT05846503.

From high-school sciences to university accounting in South Africa: how prior learning affects students’ success

Enrolling students in accounting programs based on their proficiency in English, Mathematics, and Accounting is a prevalent practice in many South African institutions of higher learning. However, certain institutions admit students into accounting programs based solely on their proficiency in English and Mathematics. This study posits that such students encounter challenges in acclimating to the accounting science milieu, consequently impeding their academic success. The research draws from the assessment of 112 first-year BCom (Bachelor of Commerce) Accounting Sciences students during the 2023 academic year. The findings affirm that students enrolled based on competency in Accounting, English, and Mathematics outperform those enrolled solely based on English and Mathematics competency. This underscores the necessity for further investigation into the determinants of success among students in accounting programs. Nonetheless, the study corroborates that self-determination and proactivity are significant contributors to success, notwithstanding students' lack of prior exposure to accounting principles.

Legal Support of Artificial Intelligence in Countering Anti-Money Laundering and Terrorism Financing Regimes in the BRICS Plus Countries

The increasing integration of artificial intelligence technologies into the financial structures of the BRICS Plus countries (comprising the original member countries of Brazil, Russia, India, China, and South Africa as well as the four new member countries of Egypt, Ethiopia, Iran, and the United Arab Emirates) presents both opportunities and challenges in combating economic crimes, which include money laundering and terrorism financing. This article explores the complex regulatory landscape that governs the application of artificial intelligence in these efforts. It examines how artificial intelligence can enhance the performance of anti-money laundering and counter-terrorism financing frameworks by enabling the evaluation of massive datasets, the identification of anomalous transaction patterns, and the automation of compliance procedures. Simultaneously, the article addresses the highly challenging situations that arise when using artificial intelligence. For instance, these technologies can make it difficult to understand the fluctuation of illicit price ranges, thereby complicating efforts to determine their origins and destinations. Through a comparative analysis of the frameworks throughout the BRICS Plus countries, this research highlights the varying levels of regulatory readiness of these frameworks and proposes pathways for harmonizing artificial intelligence-driven economic security measures. The overarching goal of an artificial intelligence model is to enhance both the effectiveness and the integrity of the financial sectors in the BRICS Plus consortium, necessitating a collaborative approach to combating financial crimes in an increasing number of digital economies across the world.

THE LEGAL STATUS OF TRADE UNIONS AND POTENTIAL GROUNDS ON WHICH THEY MAY INCUR LIABILITY

Employees exercise their right to freedom of association by forming or joining trade unions. It is not required that a trade union be registered to function as such. However, under the Labour Relations Act (LRA), there are a number of benefits available to registered trade unions. A registered trade union acquires the status of a body corporate with rights and duties. However, it functions through natural persons, and those who represent it may not be held liable if they act in line with the union’s constitution and within their authority. This article is aimed at considering the legal status of trade unions in South Africa and in the United Kingdom (UK) respectively. It further considers different circumstances under which a trade union may incur liability, including instances where there is non-compliance with the union’s constitution, a breach of contract or delict, or a discrimination claim.

Social discounting in a symmetric giving and taking frame: An artifactual field experiment with young South African adults.

In the dictator game, the evidence that giving is equivalent to taking is mixed. The purpose of this study was to investigate framing effects (giving/taking) on social-discounting rates among young African adults from an informal settlement in South Africa. Employing a within-participant design, these young adults completed a series of incentivized dictator games with an isomorphically equivalent giving and taking frame at each of eight social distances. Altruism was measured by the social-discounting rate, and framing effects were assessed using generalized linear regression. The study provides empirical evidence that prosocial behavior among young South African adults is subject to framing because exponential, hyperbolic, and q-exponential social-discounting rates in all instances were lower in the taking than in the giving frame. This difference may be the result of greater "egalitarianism" and "selflessness" elicited by the taking frame, which likely is a product of the experiment's particular social and economic field context. More comparative research is required to establish the working of specific mechanics of morality that may operate differently in diverse socioeconomic contexts, thus contributing to elucidating the heterogeneous nature of findings in this area of study.

Adoption of artificial intelligence for manufacturing SMEs’ growth and survival in South Africa

This study advances research and practice related to adopting artificial intelligence (AI) in the context of South Africa (SA). The study evaluated AI adoption by South African manufacturing Small and Medium Enterprises (SMEs); established the challenges faced by manufacturing SMEs in adopting AI; and developed a framework for adopting AI for manufacturing SMEs’ growth and survival. The study adopted a systematic literature review approach. Articles from Scopus and Google scholar databases, ranging from the years 2018 to 2024, were used. Of the 206 articles found, 54 were shortlisted. The systematic review analysis was performed using the PRISMA framework. The results identified AI adoption by South African manufacturing SMEs is low, limiting their innovation and productivity. The results also show, despite the numerous benefits AI adoption can offer manufacturing SMEs in the country, a major constraint is the lack of a framework to enhance adoption and implementation. Hence, this study was conducted to develop a framework to improve AI adoption by South African manufacturing SMEs. The findings contribute to the body of knowledge and provide new insights to manufacturing SME owners/managers, policymakers and practitioners into AI adoption to enhance manufacturing SMEs’ ability to compete on the global stage.

BRICS Alliance: A SWOT Analysis and the Potential Implications for Ending the Dominance of the USD

The group known as BRICS, comprising Brazil, Russia, India, China, and South Africa, came into being when its members decided to join hands to challenge the economic and political power of the wealthier nations of North America and Western Europe and expanded as BRICS+ when Egypt, Ethiopia, Iran, Saudi Arabia, and the United Arab Emirates entered the alliance with the same goals. Among the main reasons that led to the formation of the bloc was to put an end to the global dominance of the United States dollar (USD). Today, the BRICS+ bloc is motivated more than ever to find a solution to the ever-growing sanctions imposed by the United States (U.S.) on its member states as well as to cope with the fluctuating market situations that are merely based on the USD. The effectiveness of the newly expanded bloc’s alliance is the need of the hour, and for this purpose, the current study conducted a SWOT analysis to evaluate the bloc’s strengths, weaknesses, opportunities, and threats. The study took the facts and figures associated with the BRICS member states and their dealings with the U.S. and tried to analyze the effectiveness of this bloc should its members decide to conduct business with each other in a common currency. Furthermore, the study also evaluated the reasons behind the concept of de-dollarization and the benefits it offers the member states of the BRICS bloc. Additionally, the study proposes essential recommendations, such as the formulation of necessary measures to deal with potential disagreements that may arise regarding the choice of a common currency that should be used for trade among the member countries. Such an application of the study is an entirely novel application in the current area of research with the potential to open new horizons for future research considering the new targets of the BRICS+ group.

Temporal Variability of Hydroclimatic Extremes: A Case Study of Vhembe, uMgungundlovu, and Lejweleputswa District Municipalities in South Africa

The current study investigated hydroclimatic extremes in Vhembe, Lejweleputswa, and uMgungundlovu District Municipalities based on streamflow data from 21 river gauge stations distributed across the study site for the period spanning 1985–2023. Statistical metrics such as the annual mean and maximum streamflow, as well as trends in annual, maximum, seasonal, and high/low flow, were used to evaluate the historical features of streamflow in each of the three district municipalities. Moreover, the Standardized Streamflow Index (SSI) time series computed from streamflow observations at 3- and 6-month accumulation periods were used to assess hydroclimatic extremes, including drought episodes, proportion of wet/dry years and trends in SSI, drought duration (DD), and drought severity (DS). The results indicate that the three district municipalities have experienced localized and varying degrees of streamflow levels and drought conditions. The uMgungundlovu District Municipality in particular has experienced a significant decline in annual and seasonal streamflow as well as an increase in drought conditions during the 38-year period of analysis. This is supported by the negative trends observed in most of the assessed metrics (e.g., annual, maximum, seasonal, low/high flow, and SSI), whereas DD and DS showed positive trends in all the stations, suggesting an increase in prolonged duration and severity of drought. The Lejweleputswa District Municipality depicted positive trends in most of the assessed metrics, suggesting that streamflow increased, whereas drought decreased in the region over the 38-year period of study. Moreover, the Vhembe District Municipality experienced both negative and positive trends, suggesting localized variations in dry and wet conditions. The results presented in this study contribute towards drought monitoring and management efforts in support of policy- and decision-making that aim to uplift water resources management and planning at local and district municipality levels.

Perceptions on service quality at licensing service centres

Organisations in the public sector are faced with challenges in the delivery of high-quality services to clients. This research paper reports on a study conducted to determine clients’ perceptions of service quality at licensing service centres (LCSs) in the City of Tshwane (CoT) Metropolitan Municipality, South Africa. The research adopted a quantitative approach to realise the research objective. A convenience sampling method was used to collect primary data. 262 respondents participated in the research. A structured questionnaire was used to collect primary data from respondents. The research used the SERVPERF instrument to measure service quality. Respondents were asked to rate the level of service at LSCs. The descriptive data analysis method was used to analyse the primary data with the aid of a statistical software package, Statistical Package for Social Sciences (SPSS). Cronbach's alpha values were used to measure the internal consistency and reliability of the measurement scales. The results revealed that all rated service quality dimensions were average, which means that respondents neither agreed nor disagreed with statements about the level of service offered by LSCs. The research paper includes recommendations on the continuous improvement of service quality at LSCs and on future research directions.

Dietary intake and growth of HIV exposed and unexposed 6-12 months old infants in South Africa.

Factors affecting the growth of HIV-exposed-uninfected (HEU) children are multi-factorial, with limited information available on the dietary intake from 6 months. This study compared the dietary intake, micronutrient composition of breastmilk, and growth of HEU and HIV-unexposed-uninfected (HUU) infants aged 6 and 12 months in an urban setting. A repeated cross-sectional study used structured questionnaires to collect socio-demographic, dietary intake, food group data, and anthropometric measurements in the Siyakhula study. The HEU (48%) and HUU (52%) infants were included (total n = 181). At 6 months, HEU infants had lower weight-for-age z-scores (WAZ) (-0.6 ± 1.1 vs. 0.1 ± 1.2; p < 0.001), length-for-age z-scores (-0.8 ± 1.4 vs. -0.1 ± 1.2; p < 0.001), and mid-upper-arm circumference-for-age z-scores (MUACAZ) (0.5 ± 1.1 vs. 1.0 ± 0.9; p < 0.001) than HUU infants. At 12 months, HEU infants had lower WAZ, MUACAZ, and weight-for-length z-scores compared to HUU infants (p < 0.05). Stunting was found at 6 (15%) and 12 (12%) months in HEU infants. The micronutrient composition of breastmilk fed to both groups was similar. Breastfeeding rates were lower in HEU than in HUU infants at 6 (49% vs. 64%; p = 0.005) and 12 (24% vs. 46%; p = 0.002) months. Less than 3% of HEU and HUU infants achieved minimal dietary diversity scores at 12 months. Dietary intake of fat was similar in all breastfed infants, but iron and vitamin B12 were higher in non-breastfed HEU infants at 12 months. HEU infants had lower breastfeeding rates than HUU infants. A lack of dietary diversity was found in all infants. Nutrition education and counselling in the complementary feeding phase are essential for optimal growth.

Caloplaca tswaluensis (Teloschistales, Teloschistaceae): a new species from South Africa with plurilocular ascospores

Abstract The new species Caloplaca tswaluensis is described from Tswalu Kalahari Reserve, Northern Cape Province, South Africa. Caloplaca tswaluensis occurs on the trunks of Vachellia erioloba (camelthorn) trees and is characterized by its 3-septate to quadrilocular ascospores. Molecular data indicate that the new species is placed in the subfamily Teloschistoideae but cannot be assigned to any existing genus and, because its systematic position is unclear, we choose to describe it in Caloplaca s. lat. Caloplaca tswaluensis is compared with other crustose Teloschistaceae species with plurilocular ascospores.

Container buildings used for residential and business purposes in Johannesburg, South Africa and potential heat-related health risks

Background Outdoor and indoor air temperature affects human health and wellbeing. Climate change projections suggest that global temperatures will continue to increase, and this poses a threat to health. Buildings (for housing and business purposes) that can protect humans from the adverse effects of temperature are essential, especially in the context of climate change. Method In this cross-sectional study, we measured the indoor temperature inside shipping containers comprising a seven-storey block of apartments and businesses in Johannesburg, South Africa for 14 days. We assessed indoor temperature and relative humidity; evaluated measured temperatures in relation to thresholds known to be associated with adverse health risks; and sought to understand heat-health perceptions and symptoms of people living and working in shipping container units. Results Median indoor apparent temperature (AT) (a combination of temperature and relative humidity) was 16°C with values ranging from 6°C (observed at 8:00) to 42°C (observed at 17:00). Insulated units had temperatures between 2°C and 9°C cooler than the uninsulated unit. Heat-health risks from AT exposure were likely in all units, although there was variation in the number of occurrences that AT measurements exceeded the four symptom bands of caution, extreme caution, danger and extreme danger. Indoor AT was found to be 7°C higher on average when compared to outdoor AT. Some participants believed that their units were hot during hot weather and most people opened windows or did nothing during hot weather. Few participants reported experiencing adverse heat-health impacts, except for experiencing headaches (58%) and feeling tired or weak (40%). Conclusion Residents, tenants, or business owners using shipping containers should consider insulation installation and adequate windows/air conditioning for ventilation, especially in hot climates. Further research and awareness regarding heat-health risks of living or working in these spaces is needed.

Building locally anchored implementation science capacity: the case of the adolescent HIV implementation science alliance-supported local iS alliances.

The Fogarty International Center-led Adolescent HIV Implementation Science Alliance (AHISA) supports region-/country-specific implementation science (IS) alliances that build collaborations between research, policy, and program partners that respond to local implementation challenges. AHISA supported the development of seven locally-led IS alliances: five country-specific (i.e., Kenya, South Africa, Tanzania, Uganda, and Zambia), one in Central and West Africa, and one with youth researchers. This article outlines the aims, activities, and outcomes of local alliances, demonstrating how they enhance sustainable IS activities to address local challenges. We conducted a desk review of each alliance's funding applications, reports, and data from the initial findings of a larger AHISA evaluation. The review analyzes common approaches, highlights their local relevance, and summarizes initial outcomes. The local alliances have a common goal: to expand implementation of successful interventions to improve adolescent HIV. We identified four overarching themes across the local alliances' activities: capacity building, priority setting, stakeholder engagement, and knowledge dissemination. Research capacity building activities include long-term mentorship between junior and senior researchers and short-term training for non-research partners. Setting priorities with members identifies local research needs and streamlines activities. Alliances incorporate substantial engagement between partners, particularly youth, who may serve as leaders and co-create activities. Dissemination shares activities and results broadly. Local IS alliances play a key role in building sustainable IS learning and collaboration platforms, enabling improved uptake of evidence into policy and programs, increased IS research capacity, and shared approaches to addressing implementation challenges.

Understanding Heat Dissipation Factors for Fixed‐Tilt and Single‐Axis Tracked Open‐Rack Photovoltaic Modules: Experimental Insights

ABSTRACTThis paper presents the results of long‐term experiments conducted on fixed‐tilt (FT) and single‐axis tracked (SAT) open‐rack photovoltaic (PV) modules in South Africa. Utilising Faiman's heat dissipation model and data filtering method, the study demonstrates favourable comparisons of FT experimental results with literature while yielding novel heat dissipation factors for SAT modules. Enhanced heat dissipation is observed in no/low wind conditions for SAT modules compared to FT modules. Analyses reveal the influence of plane‐of‐array (POA) irradiance, wind speed and direction on module temperature, with SAT modules exhibiting greater heat dissipation stability. An investigation into data filtering methods suggests minor sensitivity for both configurations, with a slightly more pronounced impact on SAT modules. Assessments comparing module temperature predictions using diverse heat dissipation factors for FT modules reveal negligible sensitivity. This suggests that exact heat dissipation factor values may not be crucial for accurate predictions of module temperature in FT open‐rack systems. Annual power output simulations using PVsyst software demonstrate a 2.9% and 3.3% enhancement for FT and SAT configurations, respectively, when employing experimentally determined heat dissipation factors. These findings highlight the importance of realistic, configuration‐specific heat dissipation factors in optimising PV system performance, particularly in the competitive context of modern PV power plant construction and techno‐economic calculations.

Developing guidelines for nursing management of epilepsy in Ghanaian schools

BackgroundThe absence of guidelines for the nursing management of individuals living with epilepsy, who are students in Ghana, has resulted in the high dropout rates of such students. It is our hope, that in the near future, these individuals living with epilepsy will receive the needed attention, experience less stigmatization and discrimination. This, we expect, will result in better retention of such students in schools, improved academic performance and successful graduation. To achieve this, there is the need to develop appropriate guidelines and implement same for their benefit. In line with this, the study aims to develop guidelines for nurses to manage individuals living with epilepsy in Ghanaian schools.MethodologyQualitative approach will be adopted to conduct this study in two phases. In the first phase, a case study design will be deployed in the Twifo Atti-Morkwa District of the Central Region of Ghana. The case is the nursing management of individuals living with epilepsy within the school context, and the sources of information will be the general nurses, psychiatric, or community psychiatric nurses working at the schools. Within the context of the case, parents or guardians of individuals living with epilepsy in the schools as well as their teachers will be included in the study. Data will be collected through individual interviews for nurses and parents while focus group discussions will be used for the teachers. Thematic analysis will be used to analyze the data. In the second phase, guidelines will be developed using the modified e-Delphi Technique. The study will be piloted in the Komenda-Edina-Eguafo-Abrem Municipality of the Central Region of Ghana. Ethics approval for this study has been obtained from the Ethical Review Committee of the University of Pretoria in South Africa. Additionally, Administrative approvals have been obtained from the Ghana Education Service.DiscussionThe guidelines developed will form the basis for nursing management of individuals living with epilepsy in Ghanaian schools. This will help to improve educational outcomes for the individuals living with epilepsy.
