The multivocality of the nation: political imagination and transformation in the emergence of African Nationalism

AbstractAt key moments in history, political understanding and action are irrevocably transformed. What makes such moments of transformation possible? This article examines the emergence of African nationalism in South Africa, following the multivocal appeal to African nationhood made by proto-nationalist leaders and intellectuals. In doing so I examine how new political imagination can reconfigure the structure of political relations and create powerful new possibilities for political organizing and action. African proto-nationalist leaders were ‘intermediary intellectuals’ who used African nationhood to speak to three different political logics of their key audiences: a ‘progressive nationhood’ to their white colonial audience, a ‘unifying nationhood’ to their missionary-educated African audience, and a ‘traditional nationhood’ to their rural African audience. African nationhood thus had a multivocal appeal which allowed proto-nationalist leaders to bring otherwise divided audiences to support a common political project. By bridging these divided communities, proto-nationalist leaders were able to combine resources and strategies from once separated domains into novel forms of political power. Transformation in political understanding was thus a critical enabler of innovation in organization and action because it built a political project where new connections between African and colonial worlds were made politically ‘thinkable’. Speaking to the scholarship on political repertoires and the sociology of anti-colonial intellectuals, this study has broader implications for the role political ideas play in political transformation.

Assessing compliance with national guidelines in diabetes care: A study leveraging data from south Africa's National Health Laboratory Service (NHLS).

Diabetes is a major global health issue. We evaluated compliance to laboratory-based management guidelines for diabetes (type 1 and 2), essential for effective treatment and reducing diabetes-related morbidity and mortality. Our study utilized South Africa's National Health Laboratory Services (NHLS) data, focusing on patients from birth to age 80 years who underwent initial diabetes laboratory testing between January 1, 2012-January 1, 2016. Patients were categorized into type 1 (<30 years) or type 2 (≥30-80 years) diabetes based on age at first diabetes test. National diabetes guidelines recommend blood glucose to be checked every three-six months post laboratory-diagnosis. We employed a sharp regression discontinuity design to estimate the effect of a laboratory-diagnosis of diabetes on the likelihood of having a follow-up laboratory test 24 months post-diagnosis. Among patients with type 2 diabetes, the probability of a diabetes follow-up laboratory test within 24 months was 52.4% for patients presenting above the diabetes diagnosis threshold vs 31.1% for those presenting below. Although the likelihood of repeat testing rose with higher HbA1c and glucose levels, at the diagnostic threshold there was no clinically meaningful difference (risk difference: -2.2%, 95% CI: -3.3%, -1.2%). These results were consistent among patients with type 1 diabetes, those living with and without HIV, and healthcare setting. In a national laboratory cohort, diabetes laboratory-diagnosis did not lead to increased monitoring as recommended in national guidelines. Strategies to improve patient education, healthcare provider communication, and healthcare system support are essential to enhance guideline compliance and overall diabetes management.

Sexual and reproductive health and rights, HIV and migration in southern Africa: A rapid review.

Migration, a prevalent global phenomenon, significantly impacts health, particularly in low- to middle-income countries. This article presents a rapid review aimed at mapping projects, lessons and policies concerning sexual and reproductive health (SRH), HIV and migration in southern Africa. Utilising a population-concept-context framework, the review focuses on understanding the scope, nature and extent of interventions, identifying lessons learnt, and assessing existing policies and strategies. A comprehensive search strategy and screening process resulted in 19 studies and reports for inclusion. The review highlighted diverse projects across southern Africa, addressing SRH and HIV among migrants, refugees and asylum seekers. Projects ranged from peer-education interventions to community-based referral systems, aiming to improve knowledge, access and outcomes related to SRH and HIV. The lessons learnt emphasised the importance of community involvement, healthcare worker (HCW) training and inclusive policies to address migrants' diverse needs effectively. Additionally, projects facilitated cross-border collaborations and policy integration, enhancing access to SRH-HIV services and migrant health rights. Despite these efforts, challenges persist, including gender-based violence, financial barriers and xenophobic attitudes among HCWs. Limited access to comprehensive sexuality education and social protection for migrants underscores the need for further policy development and implementation. Nevertheless, existing policies, such as Botswana's inclusive HIV treatment policy and South Africa's National Strategic Plan for HIV, TB and STIs, demonstrate steps towards ensuring migrants' rights to healthcare.

The Effects of Education on Tobacco Consumption: A Panel Data Analysis

This study tests the hypothesis that acquiring more education improves health by reducing smoking habits. The study investigates whether higher levels of education influence smokers' behaviour or not. A panel dataset from South Africa's National Income Dynamic Survey (2008–2017) was used as a data collection source. The study employs a logistic model to conclude that people in South Africa with more education are less likely to smoke than those without education. Also noteworthy is the discovery that individuals with mental health-related behavioural disorders are more likely to smoke as a form of self-medication. Our results are particularly significant for policymakers since they demonstrate that education reduces the likelihood of smoking. These findings indicate the need for increased government support for educational opportunities in South Africa. In the long run, the population health of a country may benefit from free public education. Programs aimed at reducing smoking ought to focus on individuals with lower levels of education, younger people, and city dwellers because they are more likely to be engaged in smoking.

Unpacking the process of developing South Africa's national drug policy - lessons for universal health coverage.

South Africa's National Drug Policy (NDP) was first issued in 1996, at a time of considerable political change. To revisit the lessons learned from the process of development and initial implementation of the NDP. Six in-depth face-to-face interviews were held with purposively-selected key actors. Interviews, which followed pre-determined semi-structured questions, but were allowed to explore additional areas, were recorded and transcribed, and then subjected to abductive thematic analysis, informed by the Walt and Gilson model. Three key themes emerged, described as 'evidence', 'trust' and 'looking forward'. A paucity of evidence backed some of the key concepts in the NDP, and these have not been addressed as evidence has matured. The lack of trust which characterised the policy process impacted on the ways in which actors were able to or not able to engage, and therefore on the resultant content and the choices exercised. The coherence of the policy, its articulation with other health reforms, and its contribution to subsequent efforts to ensure universal health coverage in South Africa have all been weakened by the failure to revise the document over time. As South Africa advances its plans for universal health coverage, there is an urgent need to revisit key components of the NDP which are no longer fit for purpose.

Biogeographical comparison of Lagarosiphon major between native South Africa and invaded New Zealand: A natural enemy release case study?

The Enemy Release Hypothesis (ERH) suggests that the absence of natural enemies (herbivores, parasites, and diseases) in non-native environments allow exotic plants to allocate more resources towards growth and reproduction, resulting in increased invasiveness. This study uses the submerged macrophyte Lagarosiphon major (Ridl.) Moss ex Wager (Hydrocharitaceae), native to Southern Africa, as a case study of this hypothesis. This species is invasive in many parts of the world, including Ireland, the United Kingdom and New Zealand. Here, we investigate the applicability of the ERH in explaining the invasiveness of L. major in New Zealand. This was achieved by comparing L. major biomass and cover, and plant species richness between L. major’s native range in South Africa and its invaded range in New Zealand, where specialist natural enemies were presumed to be lacking. The findings revealed significantly higher L. major biomass (∼100 % increase), cover (∼28 % increase) and shoot production (∼91 % increase) in the invaded range compared to the native range. Additionally, overall species richness and abundance was negatively correlated with L. major abundance in the invaded range. Plants in the native range were associated with more natural enemies and experienced higher levels of damage relative to the invaded sites. Overall, these observations align with the ERH, but should be interpreted with caution as other influential factors such as competition were not measured. Nevertheless, this suggests that L. major could benefit from the integration of biological control measures with the existing methods of control. Two natural enemies, Polypedilum tuburcinatum Andersen (Diptera: Chironomidae) and Hydrellia lagarosiphon Deeming (Diptera: Ephydridae) have already been identified as promising candidates, for biological control of L. major in New Zealand and other regions invaded by this weed.

BRICS expansion in the news coverage of member countries: a political economy perspective

PurposeThe purpose of this research is to examine the dynamics of news coverage within Brazil, Russia, India, China and South Africa (BRICS) nations, aiming to uncover patterns and critical factors influencing political and economic development policies. By providing a comprehensive overview of macro-level and sector-level economic trends reported by member country newspapers, the study seeks to understand problem-driven analysis schemes and proposed solutions to challenges. Additionally, it aims to evaluate the economic implications of political decisions as portrayed in news coverage, scrutinize the promotion of meaningful dialog and assess the role of news in encouraging coherence among stakeholders for effective pursuit of economic development goals within the BRICS nations.Design/methodology/approachThis qualitative research involves conducting a content analysis on 11 newspapers, each published by a BRICS member country, including established and recent members. The current study analyzes the national interests, economic implications of media frames, leaders’ statements and geopolitical contexts in light of the coverage of the newspapers under study and the BRICS' inclusion of new members from a political economy perspective.FindingsAll eleven newspapers emphasize the significance of the BRICS Summit and its role in shaping economic and geopolitical dynamics. They consistently highlight the cooperative and multilateral nature of BRICS, focusing on collaboration among member nations. All newspapers emphasize the importance of the BRICS Summit as a key event in global geopolitics. For instance, they discuss the 2023 BRICS Summit in South Africa as a focal point for member countries to discuss various global issues. Each newspaper discusses BRICS' role in advocating for equitable global governance and challenging Western dominance in international affairs. Economic aspects, such as trade, financial cooperation and economic growth within BRICS, are mentioned in the coverage of all eleven newspapers, underlining the economic dimension of the group. All eleven newspapers explore the expansion of BRICS and its implications, including differing member opinions and the introduction of new member countries. However, The Buenos Aires Times (Argentina) provides an in-depth focus on Argentina’s admission to BRICS and its significance, reflecting its unique perspective as a potential member. All newspapers recognize the media’s role in shaping awareness and discourse related to BRICS, but The Buenos Aires Times specifically focuses on Argentina’s perspective and how it informs its readers about global developments. Also, unlike other newspapers, The Buenos Aires Times mentions domestic political factors, including presidential elections in Argentina and opposition to Argentina’s BRICS membership, which impact the country’s stance. The newspapers' coverage of BRICS reflects their national interests, priorities and perspectives. While geopolitical and economic aspects are prominent, the depth of analysis, the emphasis on specific economic trends and the extent of problem-driven analysis vary. These diverse viewpoints provide readers with a comprehensive understanding of BRICS and its global impact. When comparing the 11 newspapers' coverage of BRICS-related topics, it’s evident that each publication brings its unique perspective and priorities to the forefront.Research limitations/implicationsWhile this research provides valuable insights into news patterns and their influence on political and economic development in BRICS nations, certain limitations should be acknowledged. The study’s scope primarily relies on newspaper coverage, potentially omitting perspectives from other media sources.Practical implicationsThe practical implications of this research are profound. Policymakers can leverage insights to craft informed strategies, and businesses and investors can gain a nuanced understanding of economic trends and media practitioners refine their coverage. The findings promote cross-cultural understanding within BRICS nations, encouraging cooperation. Global stakeholders can navigate the political-economic landscape more adeptly. Ultimately, the research provides actionable knowledge, facilitating effective decision-making, enhancing collaboration and contributing to the sustainable development and stability of the BRICS countries and the broader international community.Social implicationsThis research carries significant social implications by encouraging a deeper comprehension of the interplay between news media, politics and economics in BRICS nations. It promotes informed civic discourse, enabling citizens to critically engage with socio-political issues. By uncovering the media’s influence, the study contributes to media literacy, empowering the public to make informed decisions. Additionally, the research enhances cross-cultural understanding, potentially mitigating biases and stereotypes. Ultimately, it strengthens the social fabric by encouraging a more informed and engaged citizenry, capable of contributing positively to the political and economic development of their respective nations within the BRICS framework.Originality/valueThis research contributes originality and value by offering a nuanced exploration of news patterns in BRICS nations, going beyond surface-level analysis. By focusing on macro- and sector-level economic trends, the study provides a unique perspective on the interplay between media narratives and economic development. The examination of problem-driven analysis and proposed solutions adds depth, offering insights into policy implications. Evaluating the economic implications of political decisions through news coverage enhances understanding. Furthermore, the research’s emphasis on promoting meaningful dialog and assessing the role of news in stakeholder coherence contributes distinctive insights, enhancing the broader understanding of the interconnections between media, politics and economic development in the BRICS context.

Memetization of the president’s speeches to the nation in South Africa as popular rhetoric elements

The proliferation of political memes in recent years allows us to assume that they are a new tool of political communication and that social networks increase the possibilities for civil society to express opinions and intervene in the debate on matters of public interest. This article aims to examine the memes that have been disseminated on Twitter since the beginning of the COVID-19 pandemic in South Africa in the wake of the president’s speeches to the nation to discover whether one can speak of a political rhetoric in memes and their argumentation. To this end, the research uses a qualitative-quantitative approach to classify the taxonomy of memes according to their content, combining the thematic classification of memes and the typology of images in digital discourse to discover the existence of the use of popular political rhetoric. The final sample comprises 351 memes, and the analysis shows that they used humour as a means of escape rather than as an effective way of sending political messages. Thus, the results reflect the existence of a resignification of popular culture that transcends memes as persuasive elements based on the inertia of popular rhetoric in contemporary political communication.

From resource curse to green growth: Exploring the role of energy utilization and natural resource abundance in economic development

AbstractThis study delves into the profound repercussions of the resource curse hypothesis within the Brazil, Russia, India, China, and South Africa (BRICS) nations from 1991 to 2022, examining the intricate interplay among natural resource abundance, energy consumption, and economic development (ED). Methodologically, it employs the cross‐sectionally augmented Dickey–Fuller test to assess stationarity and utilizes the Westerlund cointegration technique to analyze cointegration. Subsequently, the cross‐sectionally augmented autoregressive distributive lag model is deployed to explore the impact of natural resource availability, renewable and non‐renewable energy utilization, and carbon emissions on ED within these countries. The findings reveal a stark reality wherein both carbon emissions and non‐renewable energy consumption wield a consistently positive influence on short‐ and long‐term economic growth across the BRICS economies. Particularly striking is the dominant impact of non‐renewable energy consumption. However, this comes in stark contrast to the adverse effects identified with excessive resource and coal rents, signifying potential economic setbacks arising from rampant natural resource exploitation. Furthermore, the suboptimal utilization of renewable energy resources hints at a detrimental effect on ED. These results transcend the confines of developing nations, underscoring the universality of the resource curse hypothesis, affecting both developing and developed countries. The study illuminates the grave risks inherent in overreliance and overexploitation of natural resources, elucidating heightened competition that severely impedes the ED trajectory of the BRICS countries in both short and long terms. Policymakers must prioritize economic diversification, implement sustainable resource management, and invest in innovative technologies to mitigate the resource curse in BRICS nations, fostering resilience and sustainable economic growth. In conclusion, This study highlights the severe impact of the resource curse in BRICS nations, stressing the imperative for adept resource management to counter the risks linked with overdependence on non‐renewable resources and bolster sustainable economic growth.

SeqCode facilitates naming of South African rhizobia left in limbo

South Africa is well-known for the diversity of its legumes and their nitrogen-fixing bacterial symbionts. However, in contrast to their plant partners, remarkably few of these microbes (collectively referred to as rhizobia) from South Africa have been characterised and formally described. This is because the rules of the International Code of Nomenclature of Prokaryotes (ICNP) are at odds with South Africa's National Environmental Management: Biodiversity Act and its associated regulations. The ICNP requires that a culture of the proposed type strain for a novel bacterial species be deposited in two international culture collections and be made available upon request without restrictions, which is not possible under South Africa’s current national regulations. Here, we describe seven new Mesorhizobium species obtained from root nodules of Vachellia karroo, an iconic tree legume distributed across various biomes in southern Africa. For this purpose, 18 rhizobial isolates were delineated into putative species using genealogical concordance, after which their plausibility was explored with phenotypic characters and average genome relatedness. For naming these new species, we employed the rules of the recently published Code of Nomenclature of Prokaryotes described from Sequence Data (SeqCode), which utilizes genome sequences as nomenclatural types. The work presented in this study thus provides an illustrative example of how the SeqCode allows for a standardised approach for naming cultivated organisms for which the deposition of a type strain in international culture collections is currently problematic.

Language as a Tool of Divisive Politics: Perspectives on Foreign Nationals in South Africa

The role of language in a diverse and democratic society is critical for many reasons: first, it serves as a vital tool for the realisation of the right to freedom of expression. Secondly, it brings into confluence two other rights: the rights to dignity and equality. When language has the potential to cause hurt or harm, or incite others towards hatred, discrimination, or violence, then law as an instrument must be relied upon to regulate it. Political rhetoric uttered by top politicians in South Africa does not reflect the truth from a policy perspective; it incites hatred towards foreign nationals, shatters communities as fear and suspicion fill individuals who target foreign nationals and is counterproductive when one thinks of nation-building. The rhetoric exceeds the limits of legally protected speech. In addition, scapegoating foreign nationals for the country's socio-economic woes is not only dishonest but is a form of political corruption.

Burden of tuberculosis in underserved populations in South Africa: A systematic review and meta-analysis.

Identifying case-finding strategies to reduce tuberculosis (TB) incidence in high-burden countries requires better knowledge of the disease burden in key contributing populations and settings. To inform South Africa's National Tuberculosis Strategic Plan 2023-2028, we conducted a systematic review of active TB disease and latent TB infection (LTBI) prevalence and incidence in underserved populations, defined as those living in informal settlements, townships, or impoverished communities. We identified articles published from January 2010 to December 2023, assessed study quality, and conducted a meta-analysis to estimate pooled TB and LTBI prevalence stratified by HIV status. We calculated prevalence ratios for underserved populations compared to the overall South African population. The search yielded 726 unique citations. We identified 22 studies reporting TB prevalence (n = 12), TB incidence (n = 5), LTBI prevalence (n = 5), and/or LTBI incidence (n = 2) eligible for the review, including six high-quality studies. Meta-analysis demonstrated a high prevalence of TB disease among persons living without HIV (2.7% 95% CI 0.1 to 8.5%) and persons living with HIV (PLWH) (22.7%, 95% CI 15.8 to 30.4%), but heterogeneity was high (I2 = 95.5% and 92.3%, p-value<0.00). LTBI prevalence was high among persons living without HIV (44.8%, 95% 42.5 to 47%) with moderate heterogeneity (I2 = 14.6%, p-value = 0.31), and lower among PLWH (33%, 95% CI 22.6 to 44.4%) based on one study. Compared to the national average, underserved populations of persons living without HIV had a 4-fold higher TB prevalence and a 3.3-fold higher LTBI prevalence. Underserved PLWH had a 31-fold higher TB prevalence than the national average, but similar LTBI prevalence as measured in one study. Our findings illustrate that underserved populations in South Africa have a substantially higher TB and LTBI prevalence than the general population, making targeted TB interventions potentially beneficial. More research is needed to explore the heterogeneous TB epidemiology in South Africa.

The Potential Benefits and Challenges of a BRICS+ Agency for Cybersecurity Intelligence Exchange

The Brazil, Russia, India, China, South Africa (BRICS) nations lack a cohesive cybersecurity framework for intelligence exchange. The proposed expansion of the BRICS bloc calls for a BRICS+ agency dedicated to cybersecurity information sharing and analysis. Information Sharing and Analysis Centres (ISACs) are successful not-for-profit entities that centralise resources for gathering, analysing, and disseminating cybersecurity intelligence. However, founding a BRICS+ ISAC confronts challenges such as coordination complexity, financial constraints, trust deficits, linguistic diversity, and disparate legislative landscapes. This paper proposes a novel hybrid ISAC architectural model that amalgamates centralised and decentralised elements, presenting a tailored solution for the multifaceted needs of the expanding BRICS+ entity. The innovation of this model lies in its capacity to enhance cybersecurity resilience, promote efficient intelligence exchange, elevate the BRICS+ international standing, and solidify inter-nation collaboration, while being flexible enough to cater to the specific legal, cultural, and technological variances across member countries. The proposed model's uniqueness and adaptability position it as the premier choice for actualising the BRICS+ vision for a unified cyber front.

Treatment rates and barriers to mental health service utilisation among university students in South Africa

BackgroundMental health problems are common and impairing among university students, yet only a minority of students with psychological disorders access treatment. Understanding barriers to treatment is integral to planning services, especially in resource constrained settings like South Africa (SA).MethodsData collected across 17 institutions in the online SA National Student Mental Health Survey were used to: (1) estimate 12-month prevalence of common mental health problems and self-harm; (2) estimate the proportion of students receiving treatments for the various mental health problems; (3) explore barriers to treatment; and (4) investigate sociodemographic predictors of treatment mediated through the various barriers endorsed by students with mental health problems. Prevalence analyses were carried out using cross-tabulations and prediction analyses using modified Poisson regression models.ResultsPrevalence of clinically significant mental health problems is high relative to international comparisons, with the prevalence of severe, mild and moderate symptoms of any disorder and/or self-harm of 24.8% (SD = 0.3), 18.8% (SD = 0.3) and 27.6% (SD = 0.4) respectively. Treatment rates were 35.2% (S.E. = 0.6) among students with mental health problems who perceived need for treatment and 21.3% (S.E. = 0.4) irrespective of perceived need. Treatment rates were highest for mood disorders (29.9%, S.E. = 0.6) and lowest for externalising disorders (23.8%, S.E. = 0.5). Treatment rates were much less variable across disorder types among students with perceived need than irrespective of perceived need, indicating that perceived need mediated the associations of disorder types with received treatment. Adjusting for disorder profile, probability of obtaining treatment was significantly and positively associated with older age, female gender, study beyond the first year, traditional sexual orientation, and diverse indicators of social advantage (full-time study, high parent education, and attending Historically White Institutions). Among students with mental health problems, numerous barriers to treatment were reported adjusting for disorder profile, including lack of perceived need (39.5%, S.E. = 0.5) and, conditional on perceived need, psychological (54.4%, S.E. = 1.0), practical (77.3%, S.E. = 1.1), and other (79.1%, S.E. = 1.1) barriers. Typically, students reported multiple barriers to treatment. Differences in perceived need explained the gender difference in treatment, whereas practical barriers were most important in accounting for the other predictors of treatment.ConclusionMental health problems are highly prevalent but seldom treated among SA university students. Although many barriers were reported, practical barriers were especially important in accounting for the associations of social disadvantage with low rates of treatment. Many of these practical barriers are however addressable.

Energy efficiency in the South African mining sector: A case study at a coal mine in Mpumalanga

Energy efficiency is a cost-effective way of both bolstering energy security and limiting the harmful effects of energy use on the environment. Mining is an inherently energy-intensive activity, and the 2008 revision of South Africa's National Energy Efficiency Strategy (NEES) set a target of a 10% reduction in energy consumption by 2015 for the mining sector. In this study, we investigate the effectiveness of the NEES in improving energy efficiency in the South African coal mining sector by surveying energy intensity at a number of operations, and analysing energy efficiency trends and energy use by process and energy carrier at an underground coal mine in Mpumalanga. Most mines surveyed exhibit an increase in energy intensity over time. At the case study mine, the increase was primarily due to increased energy use in the beneficiation and discard reclaiming processes. Trends in energy consumption are a poor reflection of trends in energy intensity, as a decline in energy consumption is most easily achieved by reducing production. A more appropriate metric for energy efficiency at coal mines is energy intensity, defined as energy use per unit of saleable product, relative to a multi-year baseline. The evidence suggests that the NEES has been ineffective in promoting energy efficiency in South African coal mines. We propose that greater success could be achieved by monitoring and reporting on energy intensity at the process level, and by incentivizing energy efficiency gains.

Evaluation of the accuracy of the Asanté assay as a point-of-care rapid test for HIV-1 recent infections using serum bank specimens from blood donors in South Africa, July 2018 - August 2021.

Point-of-care (POC) rapid recency testing can be used as a cost-effective tool to identify recently infected individuals (i.e. infected within the last 12 months) in near-real time, support epidemic control and identify hotspots for transmission as part of recent infection surveillance. To evaluate the performance of the Asanté (HIV-1) rapid recency assay as a POC rapid test among blood donors in South Africa (SA). The study was a cross-sectional and validity study of the Asanté HIV-1 Rapid Recency Assay performed on 715 consecutively archived plasma donor specimens from the SA National Blood Services to determine their recency and established HIV infection status. ELISA and rapid assays for HIV antibody detection were used as the reference-testing standard for confirming an infection, while the Maxim HIV-1 limiting antigen (LAg) avidity assay was used as a reference for comparing HIV recency status. Validity tests (sensitivity, specificity, negative and positive predictive values) and Cohen-Kappa tests of the agreement were conducted to compare the Asanté HIV-1 rapid recency assay results with the reference tests. Of the 715 studied blood samples, 63.1% (n=451/715) were confirmed to be HIV-positive based on the reference standard. The sensitivity and specificity of the Asanté HIV-1 rapid recency assay in diagnosing established HIV infection compared to the ELISA were 98.4% (95% CI 96.7 - 99.3) and 99.6% (95% CI 97.6 - 100), respectively. Compared with HIV rapid assay, the sensitivity and specificity of the Asanté HIV-1 rapid recency assay was 98.7% (95% CI 97.0 - 99.4) and 99.2% (95% CI 97.1 - 100), respectively. Of the 451 HIV-positive blood samples, 43% were confirmed as recent HIV infections by the Maxim HIV-1 LAg avidity assay. There was high agreement between the Asanté HIV-1 rapid recency assay and the Maxim HIV-1 LAg avidity assay (94.1%, k=0.879, p<0.0001). The sensitivity and specificity of the Asante HIV-1 assay was 89.4% (95% CI 84.0 - 93.0) and 97.7% (95% CI 94.8 - 99.0), respectively. The Asanté HIV-1 rapid recency assay test results demonstrated high accuracy (>90%) compared with the HIV ELISA and rapid assays for determining established infection and the Maxim HIV-1 LAg avidity assay for classifying recent HIV-1 infections. The assay's sensitivity for established infections was below the World Health Organization criteria (<99%) for POC devices. The Asanté HIV-1 rapid recency assay can be used to distinguish between recent and long-term infections, but may not be considered a POC test for determining HIV infection.

Integration of Renewable-Energy-Based Green Hydrogen into the Energy Future

There is a growing interest in green hydrogen, with researchers, institutions, and countries focusing on its development, efficiency improvement, and cost reduction. This paper explores the concept of green hydrogen and its production process using renewable energy sources in several leading countries, including Australia, the European Union, India, Canada, China, Russia, the United States, South Korea, South Africa, Japan, and other nations in North Africa. These regions possess significant potential for “green” hydrogen production, supporting the transition from fossil fuels to clean energy and promoting environmental sustainability through the electrolysis process, a common method of production. The paper also examines the benefits of green hydrogen as a future alternative to fossil fuels, highlighting its superior environmental properties with zero net greenhouse gas emissions. Moreover, it explores the potential advantages of green hydrogen utilization across various industrial, commercial, and transportation sectors. The research suggests that green hydrogen can be the fuel of the future when applied correctly in suitable applications, with improvements in production and storage techniques, as well as enhanced efficiency across multiple domains. Optimization strategies can be employed to maximize efficiency, minimize costs, and reduce environmental impact in the design and operation of green hydrogen production systems. International cooperation and collaborative efforts are crucial for the development of this technology and the realization of its full benefits.

Using Data Tools and Systems to Drive Change in Early Childhood Education for Disadvantaged Children in South Africa.

In line with United Nations Sustainable Development Goal (SDG) 4.2, South Africa's National Development Plan commits to providing high-quality early childhood education to all children by 2030 to drive improved child outcomes. Prior to 2016, South Africa lacked reliable, locally standardised, valid, and cross-culturally fair assessment tools for measuring preschool quality and child outcomes, suitable for use at scale within a resource-constrained context. In this paper we detail the development and evolution of a suite of early learning measurement (ELOM) tools designed to address this measurement gap. The development process included reviews of literature and other relevant assessment tools; a review of local curriculum standards and expected child outcomes; extensive consultation with government officials, child development experts, and early learning practitioners, iterative user testing; and assessment of linguistic, cultural, functional, and metric equivalence across all 11 official South African languages. To support use of the ELOM tools at scale, and by users with varying levels of research expertise, administration is digitised and embedded within an end-to-end data value chain. ELOM data collected since 2016 quantify the striking socio-economic gradient in early childhood development in South Africa, demonstrate the relationship between physical stunting, socio-emotional functioning and learning outcomes, and provide evidence of the positive impact of high-quality early learning programmes on preschool child outcomes. To promote secondary analyses, data from multiple studies are regularly collated into a shared dataset, which is made open access via an online data portal. We describe the services and support that make up the ELOM data value chain, noting several key challenges and enablers of data-driven change within this context. These include deep technical expertise within a multidisciplinary and collaborative team, patient and flexible capital from mission-aligned investors, a fit-for-purpose institutional home, the appropriate use of technology, a user-centred approach to development and testing, sensitivity to children's diverse linguistic and socio-economic circumstances, careful consideration of requirements for scale, appropriate training and support for a non-professional assessor base, and a commitment to ongoing learning and continuous enhancement. Practical examples are provided of ways in which the ELOM tools and data are used for programme monitoring and enhancement purposes, to evaluate the relative effectiveness of early learning interventions, to motivate for greater budget and inform more effective resource allocation, to support the development of enabling Government systems, and to track progress towards the attainment of national and global development goals. We share lessons learnt during the development of the tools and discuss the factors that have driven their uptake in South Africa.
