Fostering effective governance through intragovernmental networks: a case of a justice, crime prevention and security cluster network
South Africa’s crime challenge remains despite substantial public sector efforts. As wicked problems, including crime, often transcend the conventional capacities of public authorities to address them effectively, the primary aim of this research was to uncover the underlying dimensions that contribute to the effective functioning of an intragovernmental collaboration network. This research adopted a case study approach to delve into the structure and efficacy of the South African Justice, Crime Prevention, and Security Cluster. The chosen methodology and insider access to senior management produced rich descriptions not previously available to offer a conceptual understanding of balances and trade-offs required during a mandated and directed collaboration. Findings offer enhanced understanding, contributing to overcoming traditional barriers in public administration networks and reforming traditional hierarchical structures to offer meaningful governance alternatives or improvements to existing structures. Specifically, this study reveals gaps in the intragovernmental network and offers insights for governance and performance enhancements. Findings emphasize the importance of fostering a collaborative culture based on performance and accountability. The study underscores the need for more robust network directives, clarifying roles and responsibilities, and enhancing leadership attributes. It stresses the importance of efficient coordination, collaborative capability, and shared purpose. The study also suggests cluster-oriented budgeting and greater involvement of key stakeholders, including civil societies, research institutions, and academic establishments. These findings contribute to improving government-led networks in addressing complex challenges
Legislative and other measures taken by government to realise the right of children to shelter
The Constitution of the Republic of South Africa , 1996 entrenches numerous socio-economic rights. One of these socio-economic rights is contained in section 26 that grants everyone the right to have access to adequate housing and section 28 that grants every child the additional right to basic shelter among others. This article aims to examine the legislative and other measures taken by the state to realise the right to shelter of children. Firstly, the legislative measures taken specifically for the realisation of children's right to basic shelter as envisaged by section 28(1)(c) will be discussed. Thereafter attention will be drawn to those measures taken to ensure the progressive realisation of section 26. Section 26 provides everyone, including children, the right of access to adequate housing. Therefore, every measure taken to realise section 26 is indirectly applicable to the realisation of section 28(1)(c) and children's right to basic shelter.The conclusion may be drawn that most of the discussed legislative and other measures are aimed at realising everyone's right of access to adequate housing, this includes children. However, most of these measures make little mention of the specific right of children to basic shelter. It is regarded as inclusive in the overall application of the legislation. Once again, it must be stressed that these legislative and other measures, in order to comply with the standard of reasonableness, must regard the interest of children to be paramount. If such legislation does not provide for the interest of children as a vulnerable group, it can be argued that the relevant legislative measure is not constitutionally valid.It is submitted that national government must recognise the importance of the role of local government, and local government should increasingly assume policy-making and implementation powers in their area. This will go a long way to building local capacity to function as effective development facilitators. As far as the resource problem is concerned, corruption in municipalities should be eradicated, while municipal capacity to manage and mobilise resources must be enhanced. The importance of co-operative government cannot be over emphasised. Without an effective integrated plan of action, which includes cooperation between all three spheres of government, as well as the participation of civil society, especially people who are directly affected by the implementation of socio-economic rights, realising the right of children to shelter will only exist on paper
A cross-sectional study of 2550 amateur cyclists shows lack of knowledge regarding relevant sports nutrition guidelines
Background: Amateur cyclists use a wide variety of supplements and nutritional substances to increase performance in addition to their training.Objectives: The intended nutritional supplement use, carbohydrate (CHO) use and hydration practices of amateur cyclists before, during and after endurance cycling were analysed. Evidence of ignorance regarding the use of sports supplements and CHO, as well as the disregard of hydration strategy was hypothesised.Methods: Amateur cyclists, of all age and sex groups, were requested to complete an online survey anonymously on the 2013 Momentum 94.7 Cycle Challenge website, a few days before the event.Results: Responses were received from 2 550 out of 30 640 race entrants (8%); representing a distribution of 75% males, 25% females, with the majority between 25 to 45 years old. Nutritional supplements were used by 59% of respondents, with 77% dose adherence, and 29% with supplement ingredient knowledge. Half of the respondents (48%) planned to carbo-load two-three days before the event, while only five percent used professional advice to scientifically calculate their carbo-loading requirements. CHO were consumed by 81% during the event. Hydration preferences during the race were sports drinks (59%) and water (22%); and after the race 45% preferred a sports drink and 40% water. Ingredients, taste, colour, and temperature were criteria used to choose a sports drink. Only 18% of respondents knew to use both colour of urine and thirstiness to determine post-race fluid requirements.Conclusion: The authors concluded that amateur cyclists had insufficient knowledge regarding nutritional supplement ingredients and usage, CHO requirements and carbo-loading practices, and hydration strategies before, during and after the event.Keywords: ergogenic aids, nutritional supplements, carbohydrate us
Effectiveness of applying dust suppression palliatives on haul roads
Dust emissions from mining activities and their impact on the
surrounding environment have been and remain one of the major
environmental impacts associated with surface mining. Dust
emissions caused by the transportation of mined material on
surface mines are the most significant contributor. In previous
studies, as much as 93% of total dust emissions were found to be
associated with this activity. Dust emissions not only have a
negative environmental impact, but also impact on vehicle
maintenance and operating costs, and can affect the health of the
surrounding communities. Acontrolled study was conducted on
haulage roads to assess the efficacy of using a
lignosulphonate-based dust palliative, compared with a water-only
strategy to suppress dust. Asection of road that is representative of
a typical mine haulage road was chosen for the study. The road
was divided into two sections: one section was treated with water
only and the other section was treated with a lignosulphonatebased
dust palliative. The water-only method was used as the
baseline for the study. Operational parameters influencing haulage
road dust emissions were monitored and data concerning vehicle
frequency, water usage, product application frequency and dust
fallout were recorded. Dust fallout on the individual test sections
was measured over the study period using non-directional dust
buckets, and real-time dust concentrations were measured using a
personal Data Ram (pDR).I-Cat

Anterior cruciate ligament injuries of the knee: Patterns of association between the mechanism of injury and pathology visualised on magnetic resonance imaging
Background: Anterior cruciate ligament (ACL) injuries are common among athletes and the general public. These injuries may lead to significant absence from all activities with associated financial and social burdens for the patient. No definitive association has been described between the mechanism of injury and the pathology to enable the implementation of preventative measures to limit these injuries.Aim: To determine whether there is an association between the mechanism of injury and the pathology seen on a magnetic resonance imaging (MRI) scan in ACL injuries.Methods: This was a cross-sectional analytical study. Eighty-seven male patients with an ACL injury and who had an MRI scan of the knee within the last two years participated in this study. Participants were contacted to give their informed consent to participate in this study. The mechanism of injury and the pathology seen on the MRI scan was noted and categorised into different groups of injuries and associated pathologies. Statistical analyses included summaries of the data and a test for the association between the mechanism of injury and the pathology. Since there were multiple pathology responses to each mechanism, a modified version of the chi-square test for independence was used. A five percent level of significance was specified.Results: MRI scans of ACL injuries indicated that the mechanism of a solid foot plant with rotation of the knee has a greater tendency to be associated with medial meniscal injuries (77%). There was also a 54% possibility for it to be associated with lateral meniscal injuries. A solid foot plant with a valgus stress on the knee showed a higher incidence of associated medial collateral ligament (MCL) injuries (41%) and femoral bone bruising (62%). These two mechanisms of injury are the most common in ACL injuries and contribute to the clinical significance found in this study. The p-value was, however, not statistically significant (p=0.44, chi-square value=20.27, df=45) for any association between the pathology and the mechanism of injury.Conclusion: Some injury mechanisms causing an ACL injury were more common than others and had more associated pathologies. The most common mechanism of injury noted in this study was a solid foot plant with either rotation of the knee or valgus stress on the knee. Strengthening the tissue structures involved in those movement patterns causing these mechanisms can possibly limit future ACL injuries in athletes and the general public.Keywords: knee injury, mechanism, association, pathology, MRI scan, preventio

The utilisation of the right of children to shelter to alleviate poverty in South Africa
Children being the most vulnerable members of society are the one's most affected by living in poverty. This unacceptable situation can inter alia be attributed to the disastrous effects of Apartheid. During this unfortunate period in our nation's history millions of people were unjustly evicted from their homes and forced to live in deplorable conditions. Moreover, many of these people were left homeless or without the necessary adequate shelter. Children who were born into these circumstances were denied basic resources such as proper shelter, food, water and health care services.
These unfortunate circumstances existed at the adoption of South Africa 's democratic Constitution. The preamble of the Constitution of the Republic of South Africa , 1996 reaffirms government's commitment to heal the inequalities of the past and improve the quality of life of all citizens. The Constitution is based on certain fundamental values, most importantly, human dignity, freedom and equality. The fact that these values are denied to those people living without access to basic resources such as adequate housing/shelter, food, water or health care services cannot be dismissed. To facilitate South Africa 's development as a democratic state based on human dignity, freedom and equality, the problem of poverty must be addressed. The Constitutional Court , in Government of the Republic of South Africa and Others v Grootboom and Others 2000 11 BCLR 1169 (CC), has recently stated that the effective realisation of socio-economic rights is key to the advancement of a value based democratic South Africa .
Section 26 of the Constitution grants everyone the right to have access to adequate housing and section 28 that grants every child the additional right to basic shelter among others. By virtue of section 28(1)(b) the primary responsibility to provide children with the necessary adequate housing/shelter is vested in their parents, unless the parents are unable to fulfil their duty or the children are removed from their care. This does not in the least mean that the state has no responsibilities to children living with their parents. The state must still provide the framework in which parents can facilitate the realisation of their children's rights. The state can fulfil this obligation by taking reasonable legislative and other measures within its available resources to realise everyone's right of access to adequate housing progressively. Therefore, it is submitted that the measures taken to realise section 26 also indirectly ensures the realisation of children's right to basic shelter (section 28(1)(c)).
It has been largely accepted by the courts and academics alike that all fundamental human rights are indivisible and interrelated. Clearly then, the state's obligations in terms of section 28(1)(c) cannot be properly interpreted without referring to the interpretation of those obligations conferred upon it by section 26(2) and the other socio-economic rights in the Constitution. Hence, section 28(1)(c) must be seen in the context of the Constitution as a whole. Put simply, the state must take reasonable legislative and other measures within its available resources to realise children's right to basic housing/shelter progressively.
This article will focus on the utilisation of the right to shelter of the child to alleviate poverty. Essential to this discussion is an effective understanding of the right to basic shelter as entrenched by section 28 of the Constitution in conjunction with the right of access to adequate housing conferred on everyone by virtue of section 26. This will be achieved by studying the general working of such rights including their limitations and enforcement.

The use of negative pressure wave treatment in athlete recovery
Background: Athletes need to recover fully to maximise performance in competitive sport. Athletes who replenish more quickly and more efficiently are able to train harder and more intensely. Elite athletes subjectively report positive results using lower body negative pressure (LBNP) treatment as an alternate method for rapid recovery, restoring and improving their impaired physical state. Objective data on the efficacy are lacking.Objectives: To investigate the effect of intermittent vacuum therapy on accelerating acute recovery following an athlete’s normal daily training schedule of strenuous exercise. Objective measurements of biological markers of muscular fatigue were used to assess recovery.Methods: Twenty-two male cricket players in a randomised cross-over study were divided into a treatment and control group respectively. Following a one-hour high-intensity gym session, the treatment group received three 30-minute LBNP exposure sessions over three consecutive days (0, 24 and 48 hours). Blood lactate and creatine kinase biomarkers were collected to measure the recovery process. After 14 days groups were crossed over and the trial repeated.Results: Heart rate and blood pressure decreased noticeably during treatment, reverting to baseline levels after treatment. Lactate concentrations decreased in both groups after exercise termination; significantly more in the treatment (0.57±0.23 mmol/l) than control group (0.78±0.22 mmol/l), p<0.001). Creatine kinase (CK) was similar in both groups. Athletes’ subjective assessments of recovery rated moderately high.Conclusion: LBNP therapy applied as treatment during routine schedule may have a systemic effect in lowering serum lactate levels, but not CK levels. Enhanced recovery of athletes is still unconfirmed
Conservation of African Leafy Vegetables in South Africa
The nutritional and cultural importance of African Leafy Vegetables has become very important in South Africa in the past few years. Recent research has also confirmed these issues, leading to the incorporation of African Vegetables into the core business of the ARC. ARC-Roodeplaat wants to improve the distribution and conservation status of African Leafy Vegetables. Geographical collection data on Amarant, Cleome gynandra, Corchorus olitorius and Vigna inguiculata was obtained from the National Botanical Institute and the data was analyzed with DIVA and Flora map. Ecogeographical distribution maps were drawn to predict the possible distribution of the species. Germplasm of African Leafy Vegetables was collected during routine visits and the conservation status was discussed with participants in the study areas of Arthurstone in Bushbuckridge, Watershed near Ladysmith and Mars/Glenroy near Polokwane. Germplasm of various species were also collected in collaboration with the Plant Genetic Resource Centre (NPGRC) of the Department of Agriculture in Arthurstone and Watershed.The NPGRC included leafy vegetables in their mandate since this trip. Seed flow diagrams were used to discuss the Watershed community’s seed exchange systems. It was clear when discussing African leafy vegetables in communities that their conservation and utilization are declining. Also looking at the trendlines of African Vegetables availability and utilization it is clear that the use and availability of African Leafy vegetables are declining due to various reasons. Two major reasons are the negative image of the African Leafy Vegetables and the increased use of “exotic” vegetables like spinach and carrots. The active promotion, use and conservation of African Leafy Vegetables are important if we want to increase the production potential and potential contribution towards food security in South Africa. This will ensure that the status of these crops is enhanced, specifically their contributing towards sustainable nutrition as well as sustainable production. Results from promotion activities in the project (reported in another paper) indicated that the negative image of African Leafy Vegetables could be reversed and also had an affect on the roll-out of the project to other areas of research such as plant protection, nutritional analysis and food safety, crop science and indigenous knowledge systems.Key Words: Ecogeographical, Conservation, Leafy vegetable Â
