The rise of emerging powers and their local political philosophies has brought about profound changes to the international structure on an ideological level. South Africa is the leading emerging power in Africa. As the core political philosophy that South Africa has been constructing in recent years, Ubuntu attempts to transcend the Western liberal democratic discourse, the Western African discourse and the nation-state discourse, in an attempt to build cultural confidence with African characteristics and to increase the power of discourse in the international arena. The content within the political philosophy of Ubuntu and the concept of a community of a shared future for mankind have a lot in common, which indicates a trend of emerging powers trying to build local political philosophies to surpass the Western political discourse system and to enhance their soft power in global nolitics. 展开更多

The extant literature has produced mixed evidence on the relationship between finan-cial development and ecological sustainability.This work addresses this conundrum by investigating financial development’s direct and indirect consequences on ecologi-cal quality utilizing the environmental Kuznets curve(EKC)methodological approach.Our empirical analysis is based on the novel dynamic autoregressive distributed lag simulations approach for South Africa between 1960 and 2020.The results,which used five distinct financial development measures,demonstrate that financial develop-ment boosts ecological integrity and environmental sustainability over the long and short terms.In the instance of South Africa,we additionally confirm the validity of the EKC theory.More importantly,the outcomes of the indirect channels demonstrate that financial development increases energy usage’s role in causing pollution while attenuating the detrimental impacts of economic growth,trade openness,and foreign direct investment on ecological quality.Moreover,the presence of an inadequate financial system is a requirement for the basis of the pollution haven hypothesis(PHH),which we examine using trade openness and foreign direct investment variables.PHH for both of these variables disappears when financial development crosses specified thresholds.Finally,industrial value addition destroys ecological quality while tech-nological innovation enhances it.This research provides some crucial policy recom-mendations and fresh perspectives for South Africa as it develops national initiatives to support ecological sustainability and reach its net zero emissions goal. 展开更多

The argument over fiscal decentralization and carbon dioxide emission(CO_(2))reduction has received much attention.However,evidence to back this claim is limited.Economic theory predicts that fiscal decentralization affects environmental quality,but the specifics of this relationship are still up for debate.Some scholars noted that fiscal decentralization might lead to a race to the top,whereas others contended that it would result in a race to the bottom.In light of the current debates in environmental and development economics,this study aims to provide insight into how this relationship may function in South Africa from 1960 to 2020.In contrast to the existing research,the present study uses a novel dynamic autoregressive distributed lag simulation approach to assess the positive and negative changes in fiscal decentralization,scale effect,technique effect,technological innovation,foreign direct investment,energy consumption,industrial growth,and trade openness on CO_(2)emissions.The following are the main findings:(i)Fiscal decentralization had a CO_(2)emission reduction impact in the short and long run,highlighting the presence of the race to the top approach.(ii)Economic growth(as represented by the scale effect)eroded ecological integrity.However,its square(as expressed by technique effect)aided in strengthening ecological protection,validating the environmental Kuznets curve hypothesis.(iii)CO_(2)emissions were driven by energy utilization,trade openness,industrial value-added,and foreign direct investment,whereas technological innovation boosted ecological integrity.Findings suggest that further fiscal decentralization should be undertaken through further devolution of power to local entities,particularly regarding environmental policy issues,to maintain South Africa’s ecological sustainability.South Africa should also establish policies to improve environmental sustainability by strengthening a lower layer of government and clarifying responsibilities at the national and local levels to fulfill the energy-saving functions of fiscal expenditures. 展开更多

Objective:To determine the prevalence of tick-borne pathogens with a particular focus on Rickettsia spp.in ticks collected from cattle in Gauteng and Limpopo Provinces,South Africa.Methods:A total of 200 ticks were collected from cattle within the Madala livestock,Pretoria,Gauteng Province and in Mankweng Township,Polokwane,Limpopo Province in 2019.The ticks were morphologically identified and processed individually for a total genomic DNA extraction.Specific primers targetting ompA,ompB,and the 17KDa genes were used for a molecular screening and delineation of Rickettsia from the extracted genetic materials using polymerase chain reaction(PCR)technique.PCR amplicons of positive samples were sequenced bidirectionally using the Sanger sequencing method.Sequences generated were processed and analysed using appropriate bioinformatics software.Results:The ticks were morphologically identified as Amblyomma spp.PCR profiling of the genomic DNA samples revealed the presence of the Rickettsia pathogen in 42(21%)of the ticks collected from both Provinces.Out of the genes profiled,14(7%)were positive for 17KDa,42(21%)for ompA and 32(16%)were positive for ompB genes respectively.The nucleotide blast of the sequenced genomes showed high similarity,as high as 100% with other reference Rickettsia(R.)africae in the GenBank.The phylogenetic analysis of the sequences further validated them as R.africae with their characteristic clustering pattern with related reference sequences.Conclusions:There is an abundance of R.africae in Amblyomma ticks collected from cattle in the study areas.This has serious public health implications as individuals who accidentally get infested with the ticks could acquire R.africae.Hence,adequate precautions in terms of sensitization of farmers about the risk and mass mobilization drive to control the vectors in the areas are highly recommended to safeguard public health. 展开更多

Mental health challenges are a severe issue that could lead to suicide if not properly addressed.South Africa has a significant burden of mental health issues,which contributes to the soaring rate of suicide.Adequate mental health-care provision could reduce the high suicide rate in South Africa.Since the apartheid regime,the country has made a series of efforts to improve mental health.This study aimed to review and examine available literature on mental health and suicide issues in South Africa and demonstrate the policy implications.This study adopted a narrative review approach.Electronic databases(PubMed,Scilit,Google Scholar and Semantic Scholar)were used to identify published articles in the English language with crucial search terms that included mental health,South African mental health policy,South Africa,suicide and policy.Literature suggests that at the provincial level,there are no adequate mental health policies,and the implementation of the country’s mental health policy is faced with many challenges,such as a shortage of professionals and finances.The review also showed that task sharing and counselling have been pilot-tested and shown to be effective methods for the prevention of mental illness and promotion of positive mental health.This study concludes that the mental health treatment gap still exists in South Africa,and this needs to be tackled using effective,multi-level counselling interventions and policy initiatives.Adequate mental health-care provision and effective implementation of mental health policy could reduce the high rate of suicide in South Africa. 展开更多

In South Africa, non-timber forest products, especially mopane worms (Imbrasia belina) have become an important source of food and cash income for rural people living in or near the mopane woodlands. However, the continued harvesting has implications for long term management of the mopane woodlands in the northern parts of South Africa. In order to keep a balance between mopane worm harvesting and biodiversity, an understand- ing of socio-economic factors influencing the harvest at household level is vital to reducing depletion and overex- ploitation of the mopane woodland resources. This study evaluated the socio-economic factors influencing mopane worm harvesting decisions in rural households in Limpopo Province, South Africa using a binary logistic regression model based on a household survey of 120 respondents. Age, gender, education, income from mopane worm sales, social capital (group affiliation), household size, lack of institution/law to regulate use, distance to the nearest har- vesting site, and regional locations were statistically significant factors influencing household mopane worm harvest decisions. Implications for policy are discussed. 展开更多

Shale gas has been the exploration focus for future energy supply in South Africa in recent time. Specifically, the Permian black shales of the Prince Albert, Whitehill, Collingham, Ripon and Fort Brown Formations are considered to be most prospective rocks for shale gas exploration. In this study,outcrop and core samples from the Ecca Group were analyzed to assess their total organic carbon(TOC), organic matter type, thermal maturity and hydrocarbon generation potential. These rocks have TOC ranging from 0.11 to 7.35 wt%. The genetic potential values vary from 0.09 to 0.53 mg HC/g,suggesting poor hydrocarbon generative potential. Most of the samples have Hydrogen Index(HI) values of less than 50 mg HC/g TOC, thus suggesting Type-Ⅳ kerogen. Tmax values range from 318℃ to601℃, perhaps indicating immature to over-maturity of the samples. The vitrinite reflectance values range from 2.22% to 3.93%, indicating over-maturity of samples. Binary plots of HI against Oxygen Index(OI), and HI versus Tmax show that the shales are of Type II and mixed Type Ⅱ-Ⅲ kerogen.Based on the geochemical data, the potential source rocks are inferred as immature to over-matured and having present-day potential to produce gas. 展开更多

We carried out SHRIMP zircon U-Pb dating on A-type granitic intrusions from the Namaqua-Natal Province,South Africa,Sverdrupfjella,western Dronning Maud Land,Antarctica and the Nampula Province of northern Mozambique.Zircon grains in these granitic rocks are typically elongated and oscillatory zoned,suggesting magmatic origins.Zircons from the granitoid intrusions analyzed in this study suggest^1025-1100 Ma ages,which confirm widespread Mesoproterozoic A-type granitic magmatism in the Namaqua-Natal(South Africa),Maud(Antarctica)and Mozambique metamorphic terrains.No older inherited(e.g.,~2500 Ma Achean basement or^1200 Ma island are magmatism in northern Natal)zircon grains were seen.Four plutons from the Natal Belt(Mvoti Pluton,Glendale Pluton,Kwalembe Pluton,Ntimbankulu Pluton)display 1050-1040 Ma ages,whereas the Nthlimbitwa Pluton in northern Natal indicates older 1090-1080 Ma ages.A sample from Sverdrupfjella,Antarctica has^1091 Ma old zircons along with^530 Ma metamorphic rims.Similarly,four samples analysed from the Nampula Province of Mozambique suggest crystallization ages of^1060-1090 Ma but also show significant discordance with two samples showing younger^550 Ma overgrowths.None of the Natal samples show any younger overgrowths.A single sample from southwestern Namaqualand yielded an age of^1033 Ma.Currently available chronological data suggest magmatism took place in the Namaqua-Natal-MaudMozambique(NNMM)belt between^1025 Ma and^1100 Ma with two broad phases between^1060-1020 Ma and 1100-1070 Ma respectively,with peaks at between^1030-1040 Ma and^1070-1090 Ma.The age data from the granitic intrusions from Namaqualand.combined with those from Natal,Antarctica and Mozambique suggest a crude spatial-age relationship with the older>1070 Ma ages being largely restricted close to the eastern and western margins of the Kalahari Craton in northern Natal,Mozambique.Namaqualand and WDML Antarctica whereas the younger<1060 Ma ages dominate in southern Natal and western Namaqualand and are largely restricted to the southern and possibly the western margins of the Kalahari Craton.The older ages of magmatism partially overlap with or are marginally younger than the intracratonic Mkondo Large lgneous Provinee intruded into or extruded onto the Kalahari Craton,suggesting a tectonic relationship with the Maud Belt.Similar ages from granitic augen gneisses in Sri Lanka suggest a continuous belt stretching from Namaqualand to Sri Lanka in a reconstituted Gondwana,formed during the terminal stages of amalgamation of Rodinia and predating the East African Orogen.This contiguity contributes to defining the extent of Rodinia-age crustal blocks,subsequently fragmented by the dispersal of Rodinia and Gondwana. 展开更多

Inquiries into rural households’engagement with smallholder agriculture remain ambiguous and complex.For this reason,research on cultivation patterns has been informed by numerous articles published in recent decades.However,studies detailing the development and progress of deagrarianization remain understudied.In attempts to bridge this knowledge gap,the study aims to provide empirical insights into the trajectories of deagrarianization in South Africa.Studies published between 1996 and 2021 were retrieved from Clarivate Web of Science for analysis.A combination of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)and bibliometric analysis was adopted to provide a comprehensive review of deagrarianization dynamics.The findings emphasize that the field of deagrarianization is gaining momentum as publications gradually emerge to indicate that although cultivation is dominant among rural households,there is a reduction in field cultivation and an increase in home-gardening in former homelands of South Africa.Furthermore,common keywords in deagrarianization literature,from a global,African and South African perspective include poverty and livelihoods.Considering that majority of deagrarianization studies analyze patterns,drivers and consequences of the phenomenon,future research needs to consider novel methodologies such as participatory GIS and new avenues that incorporate,but are not limited to,other livelihood issues such as social identities and food security.It is advised that strategies for enhancing rural development and agricultural policies focus on broader solutions that do not only sustain home-gardens but also revitalize both active and abandoned fields. 展开更多

Background: Despite public perception to the contrary, pregnancy does not offer a protective effect for suicide ideation. In low and middle income countries (LMIC) multiple concurrent risk factors including unplanned pregnancies, testing for HIV, intimate partner violence and depression may increase suicide risk among pregnant women. We examine suicide ideation among women attending routine antenatal care in rural South Africa. Method: A consecutive series of 109 women in the second half of pregnancy were enrolled in a cross-sectional study at a large primary health care facility in a rural area of KwaZulu-Natal with high HIV prevalence. Using a mixed-methods approach, women were assessed using the Major Depression Section of the Structured Clinical Interview for Depression (SCID) for DSM-IV diagnosis;qualitative interview data were collected on women’s experiences of suicide ideation and plans. Women were assessed two weeks after routine HIV testing as part of Prevention of Mother-to-Child Transmission (PMTCT) screening. Results: Both HIV-positive (49/109) and HIV-negative (60/109) women were assessed. Depression was high (51/109, 46.7%) and equally common amongst HIV-positive and negative women. Suicide ideation was high (30/109, 27.5%) with thoughts of self harm closely linked to suicide plans. Age, previous history of depression and current depression were significantly associated with suicide ideation. Close to equal numbers of HIV-positive and negative women were suicidal. Suicide methods were frequently violent and most women cited family and partnership conflict related to an unplanned pregnancy or their newly HIV-positive status as triggers to their suicide ideation. Conclusions: Rates of suicide ideation among pregnant women testing for HIV are high. Testing HIV-positive causes considerable distress, and among HIV-negative women unplanned and unwanted pregnancies are important risk factors for suicide ideation. Pregnancy brings women into increased contact with the health services with important opportunities for prevention and intervention. 展开更多

The aim of the study was to explore the decision to and the process of disclosure of parental HIV status to children. Focus group interviews were conducted with 21 parents of 39 children aged 7 - 18 years. Participants were recruited from a highly active antiretroviral treatment (HAART) program of an academic hospital in South Africa. Parents disclosed more to older children than to younger children in the same family, and the breadth and depth of the information shared was depended on the age of the child. Communication with adolescent children included topics on HIV prevention and unsafe sexual practices. For parents with a long history of sickness, disclosure occurred soon after the diagnosis was made, when they had not commenced with antiretroviral treatment (ART). They disclosed to prepare their children for HIV related emergencies and imminent death. Parents also expected support from their older children after disclosure. Some parents were forced to disclose because children suspected their HIV status, and parents could not continue to hide symptoms like severe weight loss. In addition, parents disclosed to educate children on how to protect themselves from HIV infection. For most parents, disclosure was unplanned, emotive, and burdened with anxiety and fear of rejection by their children. However, when the decision to disclose was made, parents were honest and open and informed their children that they were HIV positive. Parents may benefit from disclosure support services, and health care providers can assist parents in deciding when and how to disclose. 展开更多

Aloe dichotoma (Quiver tree) occurs in the arid regions of Namaqualand and Bushman land in South Africa, and in arid regions of southern Namibia. The Quiver trees are not only threatened by agricultural expansion, overgrazing, and mining;but also by climate changes and droughts. Previous studies show that Quiver trees are very sensitive to environmental changes, and do not respond well to extreme hot and dry conditions. This study investigates the current status of the Quiver tree within its existing environment, and also assesses the projected future changes of the Quiver tree habitat under different climatic scenarios. It provided evidence regarding the importance of the study to understanding the climate change impacts on the Quiver tree and its geographical response to climate changes. 展开更多

The whitefly,Bemisia tabaci,is a major pest of cassava,particularly in Africa where it is responsible both for the transmission of plant viruses and,increasingly,for direct damage due to feeding by high populations.To date,there have been no practical solutions to combat this emerging problem,due to the inability of the subsistence farmers that grow cassava to afford expensive inputs such as insecticides.A programme of research was carried out linking institutes in Africa,the UK and South America,to identify possible resistance sources in cassava to the whitefly,Bemisia tabaci.The South American genotype MEcu 72 and several Ugandan cassava landraces including Ofumba Chai,Nabwire 1 and Mercury showed good levels of resistance to B.tabaci.Field and screen-house experiments showed that all of the improved,high-yielding cassava mosaic disease(CMD)resistant cassava genotypes assessed were highly susceptible to B.tabaci and supported high populations of all life stages.These data support the hypothesis that the continuing high populations of cassava B.tabaci in Uganda are due,in part,to the widespread adoption of CMD-resistant cassava varieties during the CMD pandemic.They also show that the whitefly,Aleurotrachelus socialis,resistance present in the South American cassava genotypes could have broader applicability in the Old World. 展开更多

This is one of the diseases for which pre-hospital care is well codified. The objective of this study is to report the experience of the Emergency Aid Medical Service (EMAS) of BENIN in the pre-hospital management of craniocerebral trauma. 146 head injuries were cared for. 116 were male. The mean age was 32 years with extremes ranging from 2 to 77 years. Etiology in 68% of patients was a public road accident. And the request for the use of the EMAS was made by highway users for 41% of the injuries. About 5.5% were severe cranio-brain injuries, more than 75% of which had died in intensive care. In 77% of the EMAS interventions, there was an intensive care physician in the team. 34 wounded had been transported in a vacuum mattress. The rigid cervical collar was used in 8 major traumas. All the wounded were transported by ambulance. The duration of hospitalization varied from a few hours in the emergency department to 90 days in the hospital ward. 9 patients died. One of them, who died in an ambulance, was a woman. The prehospital medical care of head trauma in BENIN is still progressing. 展开更多

Pelargonium sidoides DC is used in herbal medicine for the treatment of various infections. The roots are being indiscriminately harvested for local and export trade and the collection rate is becoming unsustainable. Seed germination dynamics of this species was studied with the aim to reveal factors that influence its survival in the wild in order to adopt the appropriate germination conditions for use in ex-situ propagation and conservation program. Germination was affected by age of seeds, temperature and pre-chilling conditions. Temperature higher than 25 oC reduced germination by 60%. When seeds of P. sidoides were subjected to pre-chilling treatment for seven days, there was a significant drop in final germination by 29% compared to the other treatments. Although, final germination was not affected by different light treatments, continuous light significantly promoted germination velocity Seeds harvested from the plants grown in the green house performed better in germination than those collected from the field. The ecological implications of these observations on the propagation and conservation ofP. sidoides are discussed. 展开更多

Mining industry has significantly contributed to the prosperity of the nation with economic growth, whereas mining operation has caused Acid Mine Drainage (AMD) with the abandonment of mines. As some researchers suggest, the history of AMD is, generally, affected by the change in not only mining industry but also in social and economic conditions. Thus, historical analysis is an effective way to find the key factors of AMD. In this study, in order to find the key factors of AMD, we examine the history of the United States (U.S.) and South Africa, where their economy had been developed owing to the large-scale mining, based on the findings in the previous studies. The results indicated that the abandoned mines due to the economic depression triggered AMD in the U.S. and South Africa. While the U.S. had progressively adopted anti-AMD methods in terms of prevention, prediction, and remediation (PPR) as a comprehensive approach, especially since the 1970s onwards because of the rise of environmental consciousness as well as strict regulations, South Africa is at the early stage of implementing the regulations following PPR. The public attention should be directed to environmental conservation in addition to the implementation of the regulations in South Africa. The improvement in socio-economic conditions is, additionally, necessary for the rise of environmental consciousness in South Africa in the light of the three pillars of sustainable development: social, economic, and environmental elements. 展开更多

Objective This article aimed to present a developed model for nurse anaesthesia practice in South Africa and then to evaluate the model by national and international anaesthetist experts.Methods For the model development,a theory-generative research design was used as guided by Chinn&Kramer.The study included four steps to develop and evaluate the model:step one,concept analysis;step two,placing the concepts into relationships;step three,description and critical reflection of the model;step four,evaluation of the model.For evaluation of the model,data were collected using individual,in-depth interviews.Four South African medical specialist anaesthesiologists and four international nurse anaesthetists were interviewed.Transcribed interviews were analyzed using Tesch’s eight steps of thematic data analysis.Results The model was described in four phases:relationship phase,working phase,termination phase,and independent phase.The model shows a development process of a student nurse anaesthetist by a nurse anaesthetist facilitator to the mastery of the scope of practice of a nurse anaesthetist.Two themes(six categories)emerged through thematic analysis:the model and guidelines for implementation were found to be appropriate(model and guidelines for implementation are important because of the need for nurse anaesthetist,the model is applicable because it is described as comprehensive,the relationship phase was found to be important and the interdependence between disciplines is imperative,the affirmation that mastery has to be attained by nurse anaesthetists due to the complexity of services rendered),anticipated limitations to the South African nurse anaesthetist(the need to identify complex patients and limitations on the setting and refer to higher level of care,limitations due to red tape).Conclusions This model provides fertile soil to inform and outline the education(curriculum)and practice(scope of practice)and research for nurse anaesthesia practice in South Africa. 展开更多

Objective:This study aimed to gain an in-depth understanding of the experience of South African working mothers in the adherence to exclusive breastfeeding when returning from maternity leave.Methods:The data of the study was collected using face-to-face semi-structured interviews.Eight breastfeeding mothers were purposefully selected from two primary health care clinics in Rustenburg,North West Province,South Africa.The data were coded,categorized,and clustered into themes using Giorgi’s phenomenological analysis.Ethical considerations and measures of trustworthiness were adhered to throughout the study.Results:The findings revealed three themes:a desire for working mothers to continue the adherence to exclusive breastfeeding,workplace support for breastfeeding mothers in the adherence to exclusive breastfeeding,and an unsuitable workplace environment for the adherence to exclusive breastfeeding.Six sub-themes were identified:the need to return to the workplace soon after baby’s birth,psychological responses in the adherence to exclusive breastfeeding,lack of support from employers and coworkers in the adherence to exclusive breastfeeding,lack of or partial implementation of breastfeeding policies in the workplace,the workplace not being supportive for mothers’having to express and the workplace not being supportive for mothers’having to store breastmilk.Conclusion:Based on the findings,South African government should revisit employment policies to support working mothers who need to continue with exclusive breastfeeding after returning from maternity leave. 展开更多
