The genetic diversity of pathogenic members of the Fusarium oxysporum species complex (FOSC) has been intensively studied worldwide, yet strains occurring from native soils with low anthropogenic disturbance remain poorly understood. This study focused on 355 F. oxysporum isolates from soils with low anthropogenic activity obtained from the grassland biome of South Africa. Analysis of the translation elongation factor 1-alpha (tef-1α) gene revealed high levels of sequence type (ST) diversity within the soil population in comparison to the global dataset. Phylogenetic relationships of the South African isolates revealed that only four nested within FOSC Clade 1. This is the first report of members of the basal clade recovered from ecosystems with low anthropogenic disturbance from Sub-Saharan Africa. The remaining strains nested within Clades 2 to 5. This study contributes significantly to our understanding of the distribution of the FOSC in natural systems as we show that FOSC populations in the South African grassland biome are genetically diverse. This fills in our knowledge gap as previous studies reported only on the occurrence and diversity of the FOSC isolated from plant debris in South Africa. This is the first comprehensive survey of fusaria from grassland soils with low anthropogenic disturbance in South Africa.

Sub-Saharan Africa has to contend with many challenges, including inadequate healthcare systems, lack of optimal sanitation, and clean water and food. All of these contribute to malnutrition and an increased risk of infections, including parasitism by cestodes and trematodes. Schistosomiasis is a category-2 notifiable trematode (fluke) infection, whereas cestode (tapeworm) infections need not be reported to the South African Department of Health. Epidemiological data for helminthiasis in South Africa is scant, with a paucity of publications on the South African scenario. As such, a complete picture of the impact of helminth infections on all age groups in South Africa does not exist. These parasitic diseases not only have an impact on socio economic development of a country, community and families, but also contribute to the chronic and detrimental effects on the health and nutritional status of the host, including the impaired development of children. In order to break the cycle of poverty and disease, a strong education drive is required in schools and communities to provide effective strategies and guidelines on preventative measures that result in avoidance of exposure to infective stages of Schistosoma and Taenia tapeworms. Also, it is imperative that healthcare professionals are able to recognise the signs and symptoms, so that interventions can be promptly initiated. The current anthelmintic treatments available in South Africa are effective against cestodes and trematodes, with no drug resistance having being reported. The need for compliancy when taking anthelmintic drugs must be emphasised.

Professional  journals  are  used  to  disseminate  the  knowledge of scholars in the profession and to provide clinicians with guidance for best practice.  This  article  aimed  to  retrospectively  review  the  role  of the  South African  Journal  of  Physiotherapy  and  its  contribution  to  the profession.  An archival  research  design  was  used  to  collect  information from  the  archives of  the  South  African  Society  of  Physiotherapy website.  The  information  was retrieved  using  a  data  capture  sheet and descriptive  statistics  were  used throughout  to  establish  frequencies  for the  relevant  information.  During  the identified period, 170 articles were published. The greatest number of papers originated in South Africa (81%), 8% from the rest of Africa and 11% written by international authors. Authors with a Masters degree contributed almost 50% of the papers and those with doctorates were responsible for at least 25% of the papers. Most of the papers presented original research (81%) with secondary research such as reviews and scholarly papers accounting for 19% of the total. The most common speciality area addressed through research  was  linked  to musculoskeletal  conditions.  The  journal  appears  to  have  provided  an important  platform  for  South African academics and emerging researchers to publish their findings. It is suggested that the journal should give preference to papers that deal with issues that are unique to South Africa and sub-Saharan Africa, as these are the least likely to be published elsewhere. In addition, the journal should emphasise papers that will advance the profession.

Background: ST-elevation myocardial infarction (STEMI) is on the rise in sub-Saharan Africa. South Africa consistently fails to deliver timely reperfusion to these patients, possibly due to under-developed coronary care networks (CCN). Objectives: To determine the current perceived state of CCNs, to determine the barriers to optimising CCNs and to suggest facilitators to optimising CCNs within the South African context. Methods: A qualitative descriptive approach was employed, by performing two structured in-depth and two focus group inter- views (n=4 and 5, respectively), inviting a purposely heterogeneous sample of 11 paramedics (n=4), doctors (n=5), and nurses (n=2) working within different settings in South African CCNs. Recorded interviews were transcribed verbatim and subjected to content analysis. Results: Participants described an under-resourced, unprioritised and fragmented CCN with significant variation in perfor- mance. Barriers to CCN optimisation resided in recognition and diagnosis of STEMI, transport and treatment decisions, and delays. Participants suggested that thrombolysing all STEMI patients could facilitate earlier reperfusion and that pre-hospital thrombolysis should be considered. Participants highlighted the need for regionalised STEMI guidelines, and the need for fur- ther research. Conclusion: Numerous barriers were highlighted. Healthcare policy-makers should prioritise the development of CCNs that is underpinned by evidence and that is contextualised to each specific region within the South African health care system. Keywords: Health care system; emergency care; cardiovascular disease.

After several decades of apartheid rule, which denied human rights to the majority of the population on the ground of race and came to be regarded as a crime against humanity, South Africa adopted its first democratic Constitution in the early 1990s. The 1996 Constitution, which succeeded the 1993 interim Constitution, is considered one of the most progressive in the world. In its founding provisions, it states that South Africa is a democratic state founded on human dignity, the achievement of equality, the advancement of human rights and freedoms. The Constitution enshrines fundamental human rights in a justiciable Bill of Rights as a cornerstone of democracy. Unfortunately, in the eyes of a number of politicians, officials and lay-persons, the rights in the Bill of Rights accrue to South African citizens only. Xenophobia, which has been rampant since the end of apartheid, seems to support the idea that foreigners should not enjoy these rights. Foreign nationals have often been accused of posing a threat to South African citizens with regard to employment opportunities. In light of the South African legislation and jurisprudence, this article affirms the position of the South African labour law that foreign nationals are indeed protected by the Constitution and entitled to rights in the Bill of Rights, including the rights to work and fair labour practices.

The purpose of this article is to evaluate the engagement of farm beneficiaries in South Africa in the governance of restituted farms through communal property associations. The South African government has already spent millions of rands on land restitution to correct the imbalance of the past with regard to farm ownership by the African communities. Various methods of farm management to benefit the African society have been proposed, however, with little recorded success. This article argues that the South African post-apartheid government was so overwhelmed by political victory in 1994 that they introduced ambitious land reform policies that were based on ideal thinking rather than on a pragmatic approach to the South African situation. We used qualitative research methods to argue that the engagement of farm beneficiaries in farm management and governance through communal property associations is failing dismally. We conclude that a revisit of the communal property associations model is required in order to strengthen the position of beneficiaries and promote access to land by African communities for future benefit.

ABSTRACT This paper used qualitative methodology to explore the South African government communication and land expropriation without compensation and its effects on food security using Alice town located in the Eastern Cape Province South Africa as its case study. This was done to allow the participants to give their perceptions on the role of government communication on land expropriation without compensation and its effects on South African food security. In this paper, a total population of 30 comprising of 26 small scale farmers in rural Alice and 4 employees from the Department of Agriculture (Alice), Eastern Cape, South Africa were interviewed to get their perception and views on government communications and land expropriation without compensation and its effects on South African food security. The findings of this paper revealed that the agricultural sector plays a vital role in the South African economy hence there is a great need to speed up transformation in the sector.

Field dilution studies were conducted on three “deep” water marine outfalls located along the South African coast to establish the comparibility of actual achievable initial dilutions against the theoretical predicted values and, where appropriate, to make recommendations regarding the applicability of the different prediction techniques in the design of future outfalls. The physical processes along the 3000 km long coastline of South Africa are diverse, ranging from dynamic sub-tropical waters on the east coast to cold, stratified stagnant conditions on the west coast. Fourteen existing offshore marine outfalls serve medium to large industries and various local authorities (domestic effluent). For this investigation three outfalls were selected to represent the range of outfall types as well as the diversity of the physical conditions of the South African coastline. The predicted dilutions, using various approaches, compared well with the measured dilutions. It was found that the application of more “simple” prediction techniques (using average current velocities and ambient densities) may be more practical, ensuring a conservative approach, in pre-feasibility studies, compared to the more detailed prediction models, which uses accurate field data (stratification and current profiles), when extensive field data is not readily available.

BACKGROUND The impact of climate temperature on the counts (number of positive COVID-19 cases reported), recovery, and death rates of COVID-19 cases in South Africa's nine provinces was investigated. The data for confirmed cases of COVID-19 were collected for March 25 and June 30, 2020 (14 weeks) from South Africa's Government COVID-19 online resource, while the daily provincial climate temperatures were collected from the website of the South African Weather Service. Our result indicates that a higher or lower climate temperature does not prevent or delay the spread and death rates but shows significant positive impacts on the recovery rates of COVID-19 patients. Thus, it indicates that the climate temperature is unlikely to impose a strict limit on the spread of COVID-19. There is no correlation between the cases and death rates, an indicator that no particular temperature range is closely associated with a faster or slower death rate of COVID-19 patients. As evidence from our study, a warm climate temperature can only increase the recovery rate of COVID-19 patients, ultimately impacting the death and active case rates and freeing up resources quicker to enable health facilities to deal with those patients' climbing rates who need treatment. OBJECTIVE This study aims to investigate the impact of climate temperature variation on the counts, recovery, and death rates of COVID-19 cases in all South Africa's provinces. The findings were compared with those of countries with comparable climate temperature values. METHODS The data for confirmed cases of COVID-19 were collected for March 25 and June 30 (14 weeks) for South African provinces, including daily counts, death, and recovery rates. The dates were grouped into two, wherein weeks 1-5 represent the periods of total lockdown to contain the spread of COVID-19 in South Africa. Weeks 6-14 are periods where the lockdown was eased to various levels 4 and 3. The daily information of COVID-19 count, death, and recovery was obtained from South Africa's Government COVID-19 online resource (https://sacoronavirus.co.za). Daily provincial climate temperatures were collected from the website of the South African Weather Service (https://www.weathersa.co.za). The provinces of South Africa are Eastern Cape, Western Cape, Northern Cape, Limpopo, Northwest, Mpumalanga, Free State, KwaZulu-Natal, Western Cape, and Gauteng. Weekly consideration was given to the daily climate temperature (average minimum and maximum). The recorded values were considered, respectively, to be in the ratio of death-to-count (D/C) and recovery-to-count (R/C). Descriptive statistics were performed for all the data collected for this study. The analyses were performed using the Person’s bivariate correlation to analyze the association between climate temperature, death-to-count, and recovery-to-count ratios of COVID-19. RESULTS The results showed that higher climate temperatures aren't essential to avoid the COVID-19 from being spread. The present results conform to the reports that suggested that COVID-19 is unlike the seasonal flu, which does dissipate as the climate temperature rises [17]. Accordingly, the ratio of counts and death-to-count cannot be concluded to be influenced by variations in the climate temperatures within the study areas. CONCLUSIONS The study investigates the impact of climate temperature on the counts, recovery, and death rates of COVID-19 cases in all South Africa's provinces. The findings were compared with those of countries with comparable climate temperatures as South Africa. Our result indicates that a higher or lower climate temperature does not prevent or delay the spread and death rates but shows significant positive impacts on the recovery rates of COVID-19 patients. Warm climate temperatures seem not to restrict the spread of the COVID-19 as the count rate was substantial at every climate temperatures. Thus, it indicates that the climate temperature is unlikely to impose a strict limit on the spread of COVID-19. There is no correlation between the cases and death rates, an indicator that there is no particular temperature range of the climatic conditions closely associated with a faster or slower death rate of COVID-19 patients. However, other shortcomings in this study's process should not be ignored. Some other factors may have contributed to recovery rates, such as the South African government's timely intervention to announce a national lockout at the early stage of the outbreak, the availability of intensive medical care, and social distancing effects. Nevertheless, this study shows that a warm climate temperature can only help COVID-19 patients recover more quickly, thereby having huge impacts on the death and active case rates.

Christopher Ballantine’s focus is on timbre, in particular the timbre of the singing voice, and how this combines with the imagination to create meaning. His investigation is largely philosophical; but the growth in popularity of opera in post-apartheid South Africa provides empirical means for Ballantine to indicate this powerful but analytically neglected way of creating meaning in the performance of music. His case study shows how timbre can produce musical experiences that have a particular, and often surprising, resonance. Through interviews with leading figures in South African opera, Ballantine demonstrates that timbre is a vital wellspring of imagined meaning; it should especially be seen thus if we seek to understand the singing voice in a sociopolitical context such as that of South Africa during and after apartheid.
