Critical Reflections on the Usefulness of eConnect to a Sample of Child and Youth Care Workers in South Africa

ABSTRACT In South Africa, most children in care have been removed from homes characterized by violence, abuse, poverty, and neglect, with many of these children often exposed to multiple traumatic events. Research points to a strong causal association between child trauma and attachment difficulties. Poor attachment increases children’s risk for a range of externalizing behaviors, with related negative consequences for the child in both the short and long term. Addressing attachment difficulties of children who have experienced disrupted care is therefore vital. This paper reflects critically on the usefulness of eConnect, a trauma informed and attachment-based programme in such cases. It reports the interview-facilitated insights of 11 child and youth care workers (CYCW) from a care facility in Johannesburg, South Africa, who completed the eConnect programme in 2021. The first interviews were conducted in the last eConnect session (2021); follow-up interviews were done in 2022. The resulting insights allow evaluation of the contextual fit of eConnect for CYCW in SA and understanding of which programme aspects had enduring uptake. They nudge continued sensitivity to situational and cultural dynamics to optimize programme efficacy and best enable care workers.

First Report of Rust Caused by Phakopsora nishidana on Creeping Fig, Ficus pumila, in South Africa.

Phakopsora nishidana has recently been reported as the causal organism of rust on edible fig, Ficus carica in South Africa (SA) (Boshoff et al. 2022). This contradicted reports by Doidge (1927, 1950) and Verwoerd (1929) who listed Cerotelium fici as the causal organism of the disease in SA. Similarities in urediniospore morphology and differing taxonomic interpretations most likely contributed to the use of both pathogen names as the causal agents for fig rust (Boshoff et al. 2022; Padamsee and McKenzie 2024). In January 2023 rust was commonly observed on nursery specimens of creeping fig, Ficus pumila, a popular evergreen and fast-growing garden plant in SA. Ficus pumila is native to southern China, Indochina, and eastern Asia but has been introduced to many countries worldwide (https://powo.science.kew.org/ accessed 20 March 2024). The F. pumila rust isolate collected in Somerset West (34°07'00.70"S, 18°52'41.75"E; Western Cape (WC) province) was identified using the sequenced 5.8S rRNA-ITS2-28S rRNA locus. When used in a BLAST analysis, this F. pumila isolate (GenBank accession number OR835538) shared the best homology with the Vermont P. nishidana isolate (34°24'33.37"S, 19°08'59.24"E) (MZ047090; e-value 0.0, 99.7% identity, 1400/1404 bp) reported on edible fig by Boshoff et al. (2022). Other P. nishidana isolates with excellent homology were KY764080 (e-value 0.0, 99.8% identity, 1012/1014 bp), KY764081 (e-value 0.0, 99% identity, 882/885 bp) and MF580676 (e-value 0.0, 99.3% identity, 981/988 bp). Accessions were used in a phylogenetic study that included four other rust samples collected from F. carica trees in Somerset West, WC (OR835534; 34°03'37.26"S, 18°51'02.18"E), Onrus River, WC (OR835535; 34°24'43.10"S, 19°09'57.99"E), Elgin, WC (OR835536; 34°14'31.37"S, 19°03'05.38"E), and Bloemfontein, Free State province (OR835537; 29°05'05.1"S 26°09'09.5"E). Reference sequences were as described in Boshoff et al. (2022). Despite limited variation, all six South African isolates, including the F. pumila isolate, grouped with the three P. nishidana reference isolates, but separate from the three P. myrtacearum isolates collected from eucalyptus trees (Maier et al. 2016). Uredinia on F. pumila leaves were mostly hypophyllous and surrounded by a halo of brown, necrotic tissue. On the upper leaf surface, the lesions appeared as small, dark leaf spots with infrequent sporulation. Urediniospores were echinulate, mostly obovoid or elliptical and their cell walls pale-yellow to yellowish-brown. The mean width and length of urediniospores were 16.7 x 21.3 µm. No telia were observed. Applying standard rust inoculation and incubation procedures (Boshoff et al. 2022), F. pumila plants inoculated with P. nishidana isolate PREM63073 produced sporulating uredinia on the abaxial surface of leaves. Likewise, inoculation of F. carica cv. Kadota leaves with the F. pumila isolate OR835538 yielded sporulating lesions containing urediniospores typical of P. nishidana, on the lower surface. Based on both the DNA sequence data and controlled infection studies, our study confirmed the host status of F. pumila for P. nishidana. The occurrence of rust on creeping fig plants in nurseries, the evergreen status of the creeper, and thus the potential to harbor the pathogen during winter, are likely to contribute to the spread of fig rust in SA.

Exploring Perceptions of Advantage and Attitudes Towards Redistribution in South Africa

Tackling inequalities and poverty in South Africa has proven extremely difficult and contentious. Indeed, redistribution policies are often widely criticized both by people who argue that these policies are not far‐reaching and comprehensive enough and by those who argue they are not justified, too large‐scale and/or ineffective, and should be scaled back. While public support amongst relatively advantaged South Africans is crucial for these redistribution policies to be enacted and maintained, interestingly, we know very little about how respective groups of “advantaged” South Africans from different ethnic groups view wealth transfers and other redistribution measures aimed at reducing the prevailing inequalities in South Africa. Drawing on a series of focus group discussions, we gain insights into perceptions of advantage and attitudes towards redistribution amongst groups of black and white “advantaged” South Africans respectively. We find that both black and white “advantaged” South Africans are reluctant to part with some of their wealth in the interests of greater economic equality, citing state corruption and extended network obligations as justification. In addition, there is a shared tendency to understate their economic advantage by identifying firmly as the middle class, thereby abrogating responsibility to the super‐wealthy whilst simultaneously expressing paternalistic views towards the poor.

Independent Correlates of Glycemic Control among Adults with Diabetes in South Africa

Background: Globally, the prevalence of diabetes is increasing, especially in low- and middle-income countries (LMICs), including those in the sub-Saharan African region. However, the independent socioeconomic correlates of glycemic control as measured by hemoglobin A1C have yet to be identified. Therefore, the aim of this analysis was to understand the independent correlates of glycemic control in South Africa. Methods: Data from the 2016 South Africa Demographic and Health Survey on adults with diabetes were used for this analysis. The dependent variable, glycemic control, was defined using hemoglobin A1c (HbA1c). Independent variables included: age, gender, ethnicity, marital status, region, urban/rural residence, ability to read, education, insurance, wealth, occupation, and employment in the last year. Analysis of variance was used to test for differences in mean HbA1c for each category of all independent variables, and a fully adjusted linear regression model was used to identify independent correlates of glycemic control (HbA1c). Results: Among the 772 people included in this analysis, there were significant differences in mean HbA1c by age (p < 0.001), ethnicity (p < 0.001), place of residence (p = 0.024), wealth index (p = 0.001), and employment in the last year (p = 0.008). Independent correlates of HbA1c included age, ethnicity, and wealth index. Conclusions: This study used data from a large diverse population with a high prevalence of diabetes in sub-Saharan Africa and provides new evidence on the correlates of glycemic control and potential targets for interventions designed to lower HbA1c and improve diabetes-related health outcomes of adults in South Africa.

Exploring cranial macromorphoscopic variation and classification accuracy in a South African sample.

To date South African forensic anthropologists are only able to successfully apply a metric approach to estimate population affinity when constructing a biological profile from skeletal remains. While a non-metric, or macromorphoscopic approach exists, limited research has been conducted to explore its use in a South African population. This study aimed to explore 17 cranial macromorphoscopic traits to develop improved methodology for the estimation of population affinity among black, white and coloured South Africans and for the method to be compliant with standards of best practice. The trait frequency distributions revealed substantial group variation and overlap, and not a single trait can be considered characteristic of any one population group. Kruskal-Wallis and Dunn's tests demonstrated significant population differences for 13 of the 17 traits. Random forest modelling was used to develop classification models to assess the reliability and accuracy of the traits in identifying population affinity. Overall, the model including all traits obtained a classification accuracy of 79% when assessing population affinity, which is comparable to current craniometric methods. The variable importance indicates that all the traits contributed some information to the model, with the inferior nasal margin, nasal bone contour, and nasal aperture shape ranked the most useful for classification. Thus, this study validates the use of macromorphoscopic traits in a South African sample, and the population-specific data from this study can potentially be incorporated into forensic casework and skeletal analyses in South Africa to improve population affinity estimates.

Social implications The study underscores the importance of balancing economic growth with social and environmental considerations, highlighting the need for policies addressing inequality, poverty and environmental degradation. Originality/value This research provides a unique comparative analysis of BRICS countries’ sustainable development efficiency, challenging conventional perceptions and offering a new perspective on their progress.

Who Wants To Share? Attitudes Towards Horizontal Redistribution Across the Globe

While recent literature has extensively addressed inequalities between households or individuals, known as “vertical inequalities,” there remains a dearth of research on socio‐economic disparities among culturally defined groups, termed “horizontal inequalities” (HIs). In diverse societies, addressing such group disparities is imperative to promote economic efficiency, political stability, and social cohesion. This thematic issue investigates the level of public support for HI‐correcting policies across nine contexts: Brazil, South Africa, Nigeria, Malaysia, Kenya, Western Balkans, India, the United States, and Northern Ireland. The articles within this issue collectively identify and analyze crucial factors at the individual, group, and national levels. In this editorial, we summarize major findings, reflecting on the salience of group identity across majority and minority contexts, the role of perceptions vs more objective measures of inequality and its causes, and the significance of shifting political climates and societal discourses.

The chemical composition of the aerial parts' essential oil of Limonium lobatum (L.f.) Chaz. growing wild in Algeria.

The Limonium genus (Plumbaginaceae) includes several species of perennial herbs and shrubs belonging to a particular type of halophytes, known as 'recretohalophytes'. Limonium species are widely distributed in the Mediterranean region, mainly in the North-Eastern and Southern countries and several bioactivities have been well documented. In the present study, the chemical composition of the essential oil (EO) of the aerial parts of Limonium lobatum (L.f.) Chaz., a species never chemically previously studied and collected in Algeria, which grows in South Spain, North Africa, and SW Asia, was analysed using GC-MS. The main constituents of the EO were monoterpenes involving eucalyptol (14.21%), β-pinene (8.62%), β-myrcene (8.18%). Among the sesquiterpene compounds β-caryophyllene (8.94%) was the major one. The chemical profile of the EO presented here was compared with the EOs of previously investigated Limonium taxa. Furthermore, a complete literature review on the ethno-pharmacological uses of Limonium species was performed.

The 4DEnVar-based weakly coupled land data assimilation system for E3SM version 2

Abstract. A new weakly coupled land data assimilation (WCLDA) system based on the four-dimensional ensemble variational (4DEnVar) method is developed and applied to the fully coupled Energy Exascale Earth System Model version 2 (E3SMv2). The dimension-reduced projection four-dimensional variational (DRP-4DVar) method is employed to implement 4DVar using the ensemble technique instead of the adjoint technique. With an interest in providing initial conditions for decadal climate predictions, monthly mean anomalies of soil moisture and temperature from the Global Land Data Assimilation System (GLDAS) reanalysis from 1980 to 2016 are assimilated into the land component of E3SMv2 within the coupled modeling framework with a 1-month assimilation window. The coupled assimilation experiment is evaluated using multiple metrics, including the cost function, assimilation efficiency index, correlation, root-mean-square error (RMSE), and bias, and compared with a control simulation without land data assimilation. The WCLDA system yields improved simulation of soil moisture and temperature compared with the control simulation, with improvements found throughout the soil layers and in many regions of the global land. In terms of both soil moisture and temperature, the assimilation experiment outperforms the control simulation with reduced RMSE and higher temporal correlation in many regions, especially in South America, central Africa, Australia, and large parts of Eurasia. Furthermore, significant improvements are also found in reproducing the time evolution of the 2012 US Midwest drought, highlighting the crucial role of land surface in drought lifecycle. The WCLDA system is intended to be a foundational resource for research to investigate land-derived climate predictability.

A molecular phylogeny of Garuleum (Calenduleae, Asteraceae) in southern Africa

We present the first complete molecular phylogeny for the genus Garuleum (Calenduleae, Asteraceae), which is endemic to South Africa and Namibia. To investigate the phylogenetic relationships, sequence data from plastid trnL-trnF and nuclear ITS were analysed with Parsimony and Bayesian Inference approaches. The genus is resolved as monophyletic and G. bipinnatum is shown as the first species to diverge from the group. Four well to moderately supported subclades were identified where the species distribution ranges within a subclade were distinct. The wide distribution of G. bipinnatum was ascribed to its heterocarpic fruit, and the distribution of the genus was possibly influenced by water availability and elevation. These results confirmed the previous molecular work in which some Garuleum species were included.

Decolonising neo-colonial hegemonies in Africa: A comparative case for socialist realism in the drama and law of Kenya, Nigeria and South Africa

Through a comparative investigation of the function of socialist realism in the drama and law of Kenya, Nigeria, and South Africa, this research investigates the decolonization of neo-colonial hegemonies in Africa. Using the drama and legal systems of Kenya, Nigeria, and South Africa as comparative case studies, the research explores how African societies can challenge and demolish oppressive systems of domination sustained by colonial legacies and contemporary neo-colonial forces. Relying on the Socialist Realism and Critical Postcolonial theoretical frameworks which both support literary and artistic genre that encourages social and political transformation, the research deploys the case study analysis, comparative literature analysis and focused group discussion methods. Data obtained are subjected to content and thematic analysis. The study emphasizes how important the relationship between the legal and artistic worlds is to the fight against neo-colonialism. It further reveals the transformational potential of socialist realism as a catalyst for social change by looking at themes of resistance, social justice, and the amplifying of disadvantaged voices in drama and legal discourse. The research contributes to ongoing discussions about de-neo-colonization through this comparative case study, and emphasizes the role socialist realism plays in overthrowing neo-colonial hegemonies. The study sheds light on the distinct difficulties and opportunities these nations—and indeed, all of Africa—face in their pursuit of decolonial justice by examining the experiences of Kenya, Nigeria, and South Africa.

Citizen science and learning outcomes: assessment of projects in South Africa

This study assessed educational goals and learning outcomes in 57 citizen science projects in South Africa. Emphasising data collection as the primary objective, the findings revealed a secondary focus on environmental awareness, protection, and management, as well as education and research advancement. Notably, educational goals were often not prioritised, and formal measures for assessing learning outcomes were infrequently employed by project leaders. The study underscores the necessity for systematic approaches to evaluate the educational impacts of citizen science projects in South Africa.

Seasonal and interannual variability of heavy metals and other microelements in wild and farmed mussels Mytilus galloprovincialis in Saldanha Bay (South Africa)

The temporal fluctuations of the levels of 21 of macro- and microelements including heavy metals in soft tissues and shells of mussels from waters of Saldanha Bay (South Africa) collected in the period of 2013–2019 were analyzed by using Neutron activation analysis. The wild and farmed sets of Mytilus galloprovincialis were selected from the bays with different hydrological conditions: from open ocean bay to the relatively closed site. It was concluded that the found features of elements’ distribution could be explained by hydrological regimes, influence of the coastal runoffs and mixing of waters, which led to higher levels of heavy metals and microelements. The farmed mussels demonstrated lower maxima for many elements during the study period but could show local increasing due to intense hydrological mixing with resuspending of bottom sediments and terrigenous runoff indicated by the non-volatile elements such as Sc, Cs, Th. The obtained data were not revealed high anthropogenic influence during studied period in comparison with the other water areas. The study proposed the indicative background levels for the heavy metals and other determined elements in the Saldanha Bay area based on the maximum values from the pristine water area obtained in the considered period.

Decolonization in South African universities: storytelling as subversion and reclamation

Abstract Underscoring recurrent calls for the decolonization of university curricula in South Africa are underexplored presumptions that by only disrupting theoretical content, universities might release themselves from a colonialist grasp, that continues to dominate and distort higher education discourse. While it might be the case that certain theories hold enormous authoritative, ‘truthful’ sway, as propagated through western interpretations and norms, there are inherent problems in exclusively approaching the decolonization project as a content-based hurdle, removed from the subjectivities of students’ social, lived and learning realities. The argument advanced in this article is that until the epistemic harm of colonialism and apartheid are afforded careful recognition and attention – as in focusing on the lived experiences, realities, and stories of individuals - the hard work of de-legitimizing coloniality, and its implicit structures of hegemonies and binaries cannot unfold. In addressing these harms, I commence by describing some of the contexts of epistemic harm, promulgated through colonialism and apartheid. This is followed by a consideration of decolonization, both as theory and practice-within-context. Here, I also foreground the #Rhodesmustfall campaign, as a particular moment of painful clarity about why decolonization, as well as transformation have faltered in higher education in South Africa. In the second half, I focus on the necessity of prioritising storytelling as a deep manifestation of decolonization. Stories, I maintain, provide access into unknown lives, and can subvert the invisible, normative framings, which dictate how we live in this world. As a manifestation of decolonization, students’ stories hold profound implications for the recognition and affirmation of pluralist identities, histories, knowledge, values, and worldviews.

Using multisource remotely sensed data and cloud computing approaches to map non-native species in the semi-arid savannah rangelands of Mpumalanga, South Africa

ABSTRACT Semi-arid savannah rangelands are diverse environments (in terms of species) that play an important role in sustaining biodiversity and providing ecosystem services. However, the emergence of non-native species, as well as bush encroachment, are currently threatening these (semi-arid rangeland and grassland) ecosystems. The purpose of this study was therefore to map and quantify the spatial extents of non-native woody vegetation in the Kruger National Park and surrounding communal areas in Mpumalanga, South Africa. To achieve the study’s objectives, Sentinel-1 and Sentinel-2 remotely sensed data were combined and analysed using the random forest (RF) machine-learning algorithm in the Google Earth Engine (GEE) cloud computing platform. Specifically, spectral bands and selected spectral derivatives, e.g. enhanced vegetation index (EVI2), normalized difference moisture index (NDMI) and normalized difference phenology index (NDPI) were computed and used to map non-native woody vegetation. After optimizing the model combination, the classification outputs had an overall accuracy of 70%, with class accuracies such as producer’s accuracy (PA) and user’s accuracy (UA) ranging from 67% to 95%.It was shown in this study that using Sentinel-2 and Sentinel-1 data together led to better overall accuracy than using single sensor models when mapping semi-arid savannah rangelands. It was also found in this study that the overall classification accuracy of non-native (invasive) species using optical sensors was higher than in previous studies. On a free platform like GEE, it was possible to utilize advanced classification processes to fully exploit the informative content of Sentinel-1 and Sentinel-2 data.

Integrating 'undetectable equals untransmittable' into HIV counselling in South Africa: the development of locally acceptable communication tools using intervention mapping.

The global campaign for "Undetectable equals Untransmittable" (U = U) seeks to spread awareness of HIV treatment as prevention, aiming to enhance psychological well-being and diminish stigma. Despite its potential benefits, U = U faces challenges in Sub-Saharan Africa, with low awareness and hesitancy to endorse it. We sought to develop a U = U communications intervention to support HIV counselling in primary healthcare settings in South Africa. We used Intervention Mapping (IM), a theory-based framework to develop the "Undetectable and You" intervention for the South African context. The six steps of the IM protocol were systematically applied to develop the intervention including a needs assessment consisting of a systematic review and qualitative research including focus group discussions (FGD) and key informant (KI) interviews. Program objectives and target population were determined before designing the intervention components and implementation plan. The needs assessment indicated low global U = U awareness, especially in Africa, and scepticism about its effectiveness. Lay counsellors and clinic managers stressed the need for a simple and standardized presentation of U = U addressing both patients' needs for encouragement and modelling of U = U success but also clear guidance toward ART adherence behaviour. Findings from each step of the process informed successive steps. Our final intervention consisted of personal testimonials of PLHIV role models and their partners, organized as an App to deliver U = U information to patients in primary healthcare settings. We outline an intervention development strategy, currently in evaluation stage, utilizing IM with formative research and input from key U = U stakeholders and people living with HIV (PLHIV).

Public Health Evaluation of COVID-19 Vaccine Acceptability and Health Behaviors in South Africa: Past, Current, and Future Implications (2020–2022)

South Africa is facing a high burden of COVID-19 pandemic with low-vaccine coverage in the African Region. We aimed to investigate the temporal changes and impacts in health behaviors on vaccine acceptability in pre-, during-, and post-vaccine roll-out periods. In this cross-sectional study, we used the combined data from the nationally conducted “COVID-19 Vaccine Surveys (CVACS)” (May 2020–February/March 2022). Semiparametric regression models were used to capture the nonlinear association between the vaccine acceptability and health behaviors. Our study provided compelling evidence for a substantial decline in COVID-19 vaccine trust which shifted from 62%–70% to 26%–42% overtime. Participants younger than 40 years of age were less likely to receive the vaccine before it became available. However, this association changed in the postvaccine period with significant uptake in vaccine acceptance in younger groups. South Africans who identified themselves as black were more likely to intend to receive (aORs ranged: 1.93−3.60) and to trust the vaccine’s safety and efficacy (aORs ranged:1.79−1.23) in all time periods. “Mask wearing” and “frequent hand washing” were the most commonly reported behaviors. Given the lower rates of vaccine acceptability and a reduction in preventative health behaviors, monitoring the spread of infections is crucial and may have significant clinical and epidemiological implications.

What’s the safest way home? Mapping safe transport routes in South Africa with (and without) crime data

AbstractSafety is arguably the single biggest daily concern for commuters. Popular navigation software systems such as Google Maps, TomTom and Waze do not however currently give the same weight of consideration to crime risk when directing road users to the safest and shortest routes as they do existing traffic knowledge. In this study we propose three simple methods to delineate the safest and shortest route between any two locations in South Africa considering crime risk. The first method uses historical crime data to delineate the safest and shortest route; the second method, uses only the location of so-called ‘risky facilities’ to determine the safest and shortest route; while the third method uses a combination of both historical crime data and facility data to delineate the optimal route. We contrast the resultant routes delineating by these three methods and speculate on the policy implications of integrating this knowledge into future navigation software systems.

Radical social work in South Africa: a rapid systematic review

The social work profession defines itself as one that promotes social change and the liberation of people. In social work practice, there is often a controversy between solving problems and engaging social issues within political, economic and historical realities. The aim of this article is to determine the current landscape of radical social work within the South African context. Findings indicate that radical efforts and responses towards decolonial social work focus on locating social work in social movements, responding to the status quo and confronting neoliberal policies. A radical stance on various issues of gross human rights violations in current affairs must be considered as a critical component of reimagining social work identity in South Africa.

Elemental composition and potential health risk of vegetable cultivated in residential area situated close to abandoned gold mine dump: Characteristics of soil quality on the vegetables

The presence of toxic metals in residential areas near abandoned gold mine tailings is a major environmental issue. This study mainly aimed to investigate the elemental distribution of both toxic and essential elements in soils and leafy vegetables (Brassica oleracea) collected from eight different sites around the Davidsonville residential area, located closer to the abandoned Princess gold mine dump, Johannesburg, South Africa. The nutritional value of vegetables in the human diet was determined to assess their value to their health. The vegetables contained metals in the following descending order: Ca > Mg > Ca > Sb > Pb > Fe > Mo > Cr > Se > As > V > Ni > Co > Cd. The bioaccumulation factor (BAF) revealed that vegetables tend to accumulate most metals even (toxic) during the transfer and translocation process. Based on the recommended daily allowance (%RDA) the vegetables showed to contribute 152%, 84% and 75% toward RDA for Se, V and Ca, respectively for most adults and these play a role in human metabolic activities. The vegetables were found to be a good source of essential elements (Ca, Mg, Ni, Na, Fe) but with some traces of toxic metals such as Pb, As and Sb. Based on the health risk assessment, the vegetable posed an adverse health hazard for human consumption due to metals with high HRI >1.
