Die strafregtelike aanspreeklikheid van regspersone: Lesse uit Kanada

This contribution investigates the basis for the criminal liability of juristic persons in Canada in an attempt to gain lessons for South Africa. The Canadian position acknowledges both the fragmented nature of corporate decision-making and the reality that the collective efforts of a number of corporate role players may cause criminal conduct. Furthermore, the conduct and fault elements of corporate criminal misconduct do not have to be found in one individual. The conduct of a representative of the corporate entity may be regarded as the conduct of the corporation, whilst the fault requirement may be found to be the level of management. This approach, although not entirely ‘realistic’, takes into account the nature of modern corporate entities much better than traditional individualistic approaches to corporate criminal liability

Die verkryging van getuienis deur middel van gedwonge chirurgie

This contribution considers the question of whether South African law permits the compelled surgical intrusion into a suspect’s body in order to obtain evidence. The courts came to contradictory findings regarding this issue. Such a procedure undoubtedly constitutes an infringement of a suspect’s right to privacy and the right to freedom and security of the person. It can only be tolerated if the requirements of the constitutional limitations clause are complied with. The authors support the approach that forced surgical interventions in order to obtain evidence are not permitted by the Criminal Procedure Act and that the legislature should intervene to provide for it. Recommendations as to the approach that could be followed are made

WhatsApp-propriate? A retrospective content analysis of WhatsApp use and potential breaches in confidentiality among a team of doctors at a district hospital, South Africa

Background. There has been a steady increase in the use of electronic media and instant messaging among healthcare professionals, where it has been almost universally adopted in the workplace. The use of WhatsApp and its perceived benefits in healthcare have been extensively studied; however, there are concerns regarding the potential for ethical breaches in confidentiality through shared electronic patient information.Objectives. To identify the usage characteristics and incidence of shared patient information with WhatsApp use in a team of medical doctors in an unobserved and unregulated setting.Methods. We conducted a retrospective cross-sectional content analysis of WhatsApp messages (n=3 340) among a team of 20 doctors in a South African district hospital over 6 months. All messages found within this time period were allocated unique identifiers. The text and image messages were thematically grouped into four categories, i.e. clinical care, resource allocation, social and administrative. Messages that contained patient-identifying information were included in the analysis.Results. Of a total of 3 340 messages sent, 220 (6.6%) contained patient-identifying information. Of these, 109 (3.3%) contained non-anonymised patient information, while in 111 (3.3%) messages, the information was anonymised. The likelihood of sharing patient identifiers was proportionally much higher in shared images (odds ratio (OR) 5.1; 95% confidence interval (CI) 3.2 - 8.2; p<0.0001) compared with text messages, and in messages that related to clinical care (OR 9.3; 95% CI 2.2 - 38.8; p=0.0023) compared with those sent for resource allocation, and social or administrative purposes.Conclusions. Non-anonymised patient identifiers were found in 3.3% of messages, constituting the potential for breaching patient confidentiality. While WhatsApp groups have significant utility in co-ordinating aspects of clinical care, resource allocation, as well as social and administrative functions, the safe use of WhatsApp should be promoted to ensure that patient confidentiality is maintained

A systematic review of the effects of single-event multilevel surgery on gait parameters in children with spastic cerebral palsy

BACKGROUND: Three-dimensional gait analysis (3DGA) is commonly used to assess the effect of orthopedic single-event multilevel surgery (SEMLS) in children with spastic cerebral palsy (CP). Purpose The purpose of this systematic review is to provide an overview of different orthopedic SEMLS interventions and their effects on 3DGA parameters in children with spastic CP. METHODS: A comprehensive literature search within six databases revealed 648 records, from which 89 articles were selected for the full-text review and 24 articles (50 studies) included for systematic review. The Oxford Centre for Evidence-Based Medicine Scale and the Methodological Index for Non-Randomized Studies (MINORS) were used to appraise and determine the quality of the studies. RESULTS: Except for one level II study, all studies were graded as level III according to the Oxford Centre for Evidence-Based Medicine Scale. The MINORS score for comparative studies (n = 6) was on average 15.7/24, while non-comparative studies (n = 18) scored on average 9.8/16. Nineteen kinematic and temporal-distance gait parameters were selected, and a majority of studies reported improvements after SEMLS interventions. The largest improvements were seen in knee range of motion, knee flexion at initial contact and minimal knee flexion in stance phase, ankle dorsiflexion at initial contact, maximum dorsiflexion in stance and in swing phase, hip rotation and foot progression angles. However, changes in 3DGA parameters varied based on the focus of the SEMLS intervention. DISCUSSION: The current article provides a novel overview of a variety of SEMLS interventions within different SEMLS focus areas and the post-operative changes in 3DGA parameters. This overview will assist clinicians and researchers as a potential theoretical framework to further improve SEMLS techniques within different SEMLS focus groups. In addition, it can also be used as a tool to enhance communication with parents, although the results of the studies can't be generalised and a holistic approach is needed when considering SEMLS in a child with spastic CP

Farm-level emission intensities of smallholder cattle (Bos indicus; B. indicus–B. taurus crosses) production systems in highlands and semi-arid regions

Ruminants are central to the economic and nutritional life of much of sub-Saharan Africa, but cattle are now blamed for having a disproportionately large negative environmental impact through emissions of greenhouse gas (GHG). However, the mechanism underlying excessive emissions occurring only on some farms is imperfectly understood. Reliable estimates of emissions themselves are frequently lacking due to a paucity of reliable data. Employing individual animal records obtained at regular farm visits, this study quantified farm-level emission intensities (EIs) of greenhouse gases of smallholder farms in three counties in Western Kenya. CP was chosen as the functional unit to capture the outputs of both milk and meat. The results showed that milk is responsible for 80–85% of total CP output. Farm EI ranged widely from 20 to >1 000 kg CO$_{2}$-eq/kg CP. Median EIs were 60 (Nandi), 71 (Bomet), and 90 (Nyando) kg CO$_{2}$-eq/kg. Although median EIs referenced to milk alone (2.3 kg CO$_{2}$-eq/kg milk) were almost twice that reported for Europe, up to 50% of farms had EIs comparable to the mean Pan-European EIs. Enteric methane (CH$_{4}$) contributed >95% of emissions and manure ∼4%, with negligible emissions attributed to inputs to the production system. Collecting data from individual animals on smallholder farms enabled the demonstration of extremely heterogeneous EI status among similar geographical spaces and provides clear indicators on how low EI status may be achieved in these environments. Contrary to common belief, our data show that industrial-style intensification is not required to achieve low EI. Enteric CH$_{4}$ production overwhelmingly drives farm emissions in these systems and as this is strongly collinear with nutrition and intake, an effort will be required to achieve an “efficient frontier” between feed intake, productivity, and GHG emissions

Chronic and structural poverty in South Africa: Challenges for action and research

Ten years after liberation, the persistence of poverty is one of the most important and urgent problems facing South Africa. This paper reflects on some of the findings based on research undertaken as part of the participation of the Programme for Land and Agrarian Studies (PLAAS) at the University of the Western Cape in the work of the Chronic Poverty Research Centre (CPRC), situates it within the broader literature on poverty in South Africa, and considers some emergent challenges. Although PLAAS’s survey, being only the first wave of a panel study, does not yet cast light on short term poverty dynamics, it illuminates key aspects of the structural conditions that underpin long-term poverty: the close interactions between asset poverty, employment-vulnerability and subjection to unequal social power relations. Coming to grips with these dynamics requires going beyond the limitations of conventional ‘sustainable livelihoods’ analyses; and functionalist analyses of South African labour markets. The paper argues for a re-engagement with the traditions of critical sociology, anthropology and the theoretical conventions that allow a closer exploration of the political economy of chronic poverty at micro and macro level
