Ubuntu and values underlying the Vatsonga culture : implications for developmental social work with children

The article is based on a doctoral study submitted at the University of Pretoria.The development of the social work profession in Western countries is criticised as being irrelevant to the African context. Although developmental social work was introduced in South Africa to align the profession with African contexts and adopted in some southern African countries, the acknowledgement of African indigenous knowledge systems remains a neglected area. In this article, we present the findings of the study that explored the use of Vatsonga indigenous knowledge in child protection. By using a qualitative study as the basis, the researcher conducted semi-structured interviews with 40 Vatsonga elders who were keepers of their indigenous knowledge. The research findings indicate that beliefs and practices based on the African principles underlying ubuntu have a strong focus on enhancing the well-being of children, including orphans and vulnerable children, and could relate to the central goal and the concepts underlying developmental social work. We conclude that there is a strong association between the principles of ubuntu and developmental social work interventions that focus on the well-being of children.A Postgraduate Research Support Scholarship of the University of Pretoria.https://unisapressjournals.co.za/index.php/SWPR/indexam2023Social Work and Criminolog

Exposure to substance use in the social environment : the experiences of adolescents in the Tshwane Metropole

The premise of this study is that if exposure to substance use in the social environment of adolescents is understood, macro interventions could be recommended to promote adolescents’ right to live in a safe and sustainable environment. The aim of the study was to explore adolescents’ experiences of exposure to substance use in their social environment, other than the home. A qualitative research approach was adopted and 40 semi-structured interviews were conducted. Adolescent participants, of both genders between 11 and 18 years, were recruited across the Tshwane Metropole. The Social Learning Theory underpinned this study as it offers concepts and principles for understanding how social environmental factors impact on adolescents’ behaviour. Key findings indicated that exposure to substance use is highly prevalent amongst adolescents in the Tshwane Metropole and could be normalised in their social reality. Recommendations are offered for appropriate macro interventions in line with a developmental approach.http://www.uj.ac.za/EN/Faculties/humanities/departments/socialwork/TheSocialWorkPractionerResearcherJournal/Pages/home.aspxam2016Social Work and Criminolog

Prevalence of radiographic changes in forelimb digits and metacarpophalangeal joints of South African endurance racehorses

Submitted in fulfilment of the requirements for the degree of MSc in the Department of Companion Animal Clinical Studies at the Faculty of Veterinary Science, University of Pretoria. (http://hdl.handle.net/2263/76858)If the number of events alone is considered, endurance riding is the fastest growing and the second-most popular Fédération Equestre Internationale (FEI) discipline. Lameness is the most common cause of elimination from endurance races worldwide. To the authors’ knowledge, no studies have been published investigating the prevalence of radiographic changes in the forelimb digits and metacarpophalangeal joints (MCP) of endurance racehorses in South Africa. The study aimed to investigate the prevalence of radiographic changes in the forelimb digits and MCP joints of South African endurance racehorses. One hundred endurance racehorses registered with ERASA were volunteered by their owners to partake in the current study. Radiographs were obtained from horses competing in endurance races during the 2018–2019 endurance racing season. Radiographs included seven standard views of each distal forelimb. Radiographic images were independently evaluated by three observers, point prevalence and inter-rater reliability (IRR) was calculated. Data analysis of the forelimb digits revealed a large proportion of horses with bilateral signs of dorsopalmar hoof imbalance (95%); a diversion from a straight digital axis (91%), with an extended (broken back) proximal interphalangeal joint (67%) being the most common abnormality. Osteoarthritis of the proximal (16%) and distal (7%) interphalangeal joints was only observed in a low percentage of horses. Interestingly, the hoof-distal-phalanx-ratio of the majority (86%) of horses was more than 25% but none of these horses showed any other signs of chronic laminitis, indicating that hoof-distal-phalanx-ratio might not be a reliable indicator of chronic laminitis in this population of horses. Ossification of the ungular cartilages was observed in the majority (69%) of horses, either affecting one or both distal phalanges. Descriptive data analysis of the MCP joints showed that a large proportion of horses displayed radiological signs of MCP joint osteoarthritis (28%), with 10% being bilateral. The current study provides insight into radiographic changes and their prevalence in the distal front limbs of South African endurance racehorses. Knowledge about the prevalence of specific radiographic changes would enable equine practitioners to better evaluate and manage horses that are affected. Although no correlations were made with age, speed or number of competitive kilometres competed, the current study may serve as a basis for future research.http://www.jsava.co.zaam2023Companion Animal Clinical Studie

Safety and risk assessment tools for the South African child protection services : theory and practice

This article provides a discussion of the theoretical basis underpinning safety and risk assessment in child protection, and further describes the empirical research process involved in the development of safety and risk assessment tools and training materials for social workers in the South African child protection field. The research process is described according to the steps of intervention research. The study confirms a need for uniform safety and risk assessment tools and procedures in social work practice and highlights the critical role of collaboration between researchers and practitioners to enhance social service delivery in the protection of children at risk.http://www.crimsa.ac.za/acta.htmlam2018Social Work and Criminolog

A developmental social work perspective on problematic Internet use among university students

Problematic internet use (PIU) is a growing phenomenon worldwide. Students in higher education especially are a vulnerable group for developing symptoms associated with PIU as a result of the idiosyncratic characteristics of student life. Owing to a lacuna in local social work research on the nature, extent and impact of internet use among students in South Africa, a crosssectional survey was conducted with 498 (n = 498) second-year undergraduate students at a South African university. The results indicate that students access the internet on university campuses and at home daily through their cell phones and laptops for academic and social purposes. Although the average number of hours spent on the internet per day does not indicate PIU, the findings flag certain symptoms associated with PIU, for example, tolerance, escape from problems, and loss of control. Social workers should not be complacent, but rather introduce services to lower students’ risk of PIU. Considering the country’s adoption of social development as welfare model, developmental social work services on the preventive, early intervention and treatment levels as well as policy development are recommended.https://upjournals.co.za/index.php/SWPR/index2020-12-01pm2020Social Work and Criminolog

Research on the Vatsonga people of Southern Africa : a reflection on a case study

For decades, African researchers relied on Eurocentric concepts, models, philosophies, ethics, designs, and methods ingrained in the European research literature. The indiscriminate use of Eurocentric concepts to conceive African research is not sustainable given the uniqueness of African cultures. This situation gives impetus to the call for the development of a way of conducting research that is more suited to indigenous African contexts. The paper contains a reflection on the researchers’ past research experiences within African socio-cultural contexts. We aim to share our experiences on a research study that we conducted in Zimbabwe with the Vatsonga of Southern Africa; one of the ethnic groups that adopt an Afrocentric worldview. We discuss how we implemented theoretical perspectives, research methods, and research ethical considerations. We found that we had to adapt the implementation of our research to be aligned with the norms and practices of the Vatsonga. Research ethical considerations are highlighted as an important step towards fostering indigenised research on the continent. In addition, we propose the dissemination of research findings to include indigenous communities where the research has been conducted. This should be done through community meetings or workshops as the African people follow an oral-based tradition of knowledge transmission. The paper concludes by highlighting the need for African literature to guide researchers in conducting research studies in indigenous African communities.University of Pretoria Post Graduate Office bursaryhttps://www.ajol.info/index.php/ajswam2023Social Work and Criminolog

Interdisciplinary and multi-institutional higher learning : reflecting on a South African case study investigating complex and dynamic environmental challenges

Complex social-ecological problems need sustained interdisciplinary engagements across multiple disciplines, yet academic offerings continue to reflect disciplinary silos. To address this, a five-year program, within a developing country context, was conceived to follow an interdisciplinary research mode using a team of students and supervisors from various institutions across the disciplines of ecology, hydrology and economics. By using a flexible student training model, regional/ site specific knowledge was developed while simultaneously developing a shared vision and a model to combine information from each student project. Graduates felt enabled by the program that actively encouraged interdisciplinary interactions and engagements while simultaneously furthering disciplinary development. Cross disciplinary communication, was achieved through multiple engagement opportunities and common research outputs, all facilitated by an external boundary organization. While lengthy time frames are required for such collaborative interdisciplinary programs, researchers, higher learning institutions and funding agencies should not avoid this type of program and investment.The Water Research Commission of South Africahttp://www.journals.elsevier.com/current-opinion-in-environmental-sustainability2017-04-30hb2016Economic

Quantification of milk yield and composition changes as affected by subclinical mastitis during the current lactation in sheep

[EN] The aim of this work was to quantify, on a half-udder basis, the changes in ewe milk yield and composition caused by unilateral subclinical mastitis within the current lactation. Fluctuations due to production level, infection severity, time from the onset of infection, and lactation curves were also studied. Yield and composition of milk from half-udders of unilateral infected ewes were compared between them and with a set of healthy halves using a mixed model. The experiment was completed with a whole-udder approach on the same animals. To test the effect of intramammary infection (IMI) in the 7 wk following the onset of infection, 20 ewes that acquired unilateral subclinical mastitis during lactation and 40 healthy ewes were used. Another group of 20 unilaterally infected ewes from wk 1 of lactation and other 40 healthy ewes were studied to test the effect of IMI on lactational milk yield and composition. The individual milk loss in ewes infected during lactation was 15% for the 7 wk following the onset of infection, and 6.6% more milk was produced by the uninfected half to compensate milk lost by the infected half. Lactational milk yield loss in ewes infected from wk 1 postpartum was 17%. The changes in milk yield were noticed from the week of infection diagnosis. The production level of animals influenced the milk yield changes caused by IMI in such a way that the more productive ewes lost more milk, although these losses were proportional to their production level. On the other hand, infection severity affected milk loss between glands, being more pronounced as somatic cell count increased. A clear decrease of lactose content and casein:protein ratio due to subclinical IMI was observed and it remained throughout the postinfection period. Improving udder health status is necessary to maintain milk production and quality in dairy ewes during lactationThe authors thank the regional government of Valencia ("Generalitat Valenciana") for its support by means of a research fellowship.Martí De Olives, AM.; Díaz, J.; Molina Pons, MP.; Peris Ribera, CJ.

Measurement of W Polarisation at LEP

The three different helicity states of W bosons produced in the reaction e+ e- -> W+ W- -> l nu q q~ at LEP are studied using leptonic and hadronic W decays. Data at centre-of-mass energies \sqrt s = 183-209 GeV are used to measure the polarisation of W bosons, and its dependence on the W boson production angle. The fraction of longitudinally polarised W bosons is measured to be 0.218 \pm 0.027 \pm 0.016 where the first uncertainty is statistical and the second systematic, in agreement with the Standard Model expectation
