- Description: This research study examined whether the physical resources in rural secondary schools are adequate and are managed properly by the school principals, for quality education to be achieved in the Eastern Cape Province. The dramatic changes in South Africa recognized that the future depends on an education system which develops the full potential of all learners. Although the Constitution of South Africa is advocating for equal education for all, there are disparities which are evident in the quality of the infrastructure, especially in remote rural areas where the fundamental requirements for effective education are lacking such as, water, electricity, sanitation and basic educational equipment. This shows that, although policy and legislative frameworks for transforming the education system have been put in place, managing the change is still a key challenge especially that of physical resources. Management of physical resources illustrates the problems facing principals by pointing to the lack of basic facilities in many rural secondary schools. In terms of the provision and management, many challenges remain, like most schools do not have adequate physical facilities. School buildings such as classrooms are inadequate or unsafe with no toilets, libraries, laboratories and many learners and teachers do not have learner teaching support materials (LTSMs). On the other hand, in terms of the Constitution, the Department of Education is responsible for bringing redress, equality and to upholding the Constitutional values such as shared decision-making, transparency, shared accountability and empowerment for equal partnership with other stakeholders. The physical resource management is one of the major responsibilities of principals. Their leadership is largely about ensuring that a clear and shared sense of direction is developed for both leadership and management. The school viii system meant that schools have moved nearer to the communities they serve and this has led to schools being more accountable to their communities. This study further investigated whether there is a significant correlation between the management of physical resources and quality education as well as the eradication of poverty in the rural secondary schools of the ECP. The proper execution of the management tasks of planning, organizing, leading, and controlling (POLC) by the principals have contributed extensively to the success of the schools. Therefore, this will mean that the act of managing physical resources through POLC and the process of working with or through SGBs, teachers, parents, learners, EDOs and the community at large to achieve set goals of education of relevance, excellence and quality education by effectively and efficiently using the physical resources in a school climate and environment that is collegial. The study showed that there is a link between management tasks (POLC) and collegial style of leadership in the school. The literature reviewed supported the view that the invitational style of leadership and collegiality increase the potential of a school to manage its physical resources economically, efficiently and effectively, particularly in a climate where the resource handlers take ownership of the school especially in remote rural settings. The 255 out of 300 subjects (85%) chosen to participate in this study were selected on the basis of their accessibility. Convenience sampling was used to conduct the study as this ensured that the population represented stakeholders that manage physical resources at schools, such as deputy principals, head of departments and teachers. Questionnaires were distributed, completed and collected personally. The questionnaires were analyzed and gaps such as the effects of lack of physical resources and how the learners’ profile were affected were reinforced by individual and group interviews that were semi-structured as ix well as participant observations from principals at O.R Tambo, Chris Hani and Amathole District Municipalities were conducted. It was deduced from the statistical data presented that there is a significant correlation between the principals’ management tasks and the quality of education. This shows that the more the principals blend properly planning, organizing, leading and control management tasks the more the physical resources will be managed better, that is, effectively, efficiently, economically and transparently and the less the bringing together of management tasks the less the meaningful management of physical resources will be. The study supported the hypothesis that a combination of management tasks performed by the principals positively influences the proper management of physical resources in rural secondary schools of ECP. The study rejects both null hypotheses that there is no significant correlation between planning, organising, leading and controlling as leadership functions of PRs and the quality of education in rural secondary schools of ECP as well as, that principals of rural secondary schools are not expected to possess adequate leadership knowledge and skills to effectively manage available PRs in their rural secondary schools. This study affirms the view that adequate physical resources are crucial as well as the appropriate management skills of principals for high quality education to be achieved in rural secondary schools. Without adequate physical resources, proper handling of the limited physical resources and the possession of management skills by principals, rural schools are less likely to succeed in their efforts to improve education.

- Description: Liquid phase catalytic hydrodechlorinations can provide a convenient and environmentally friendly method for treating organic chlorinated compounds in waste streams generated during the manufacturing of agrochemicals. During such treatment hydrochloric acid is generated as a by-product, which can be easily neutralized employing a base to yield an inorganic salt. This work describes the results obtained during the liquid phase hydrodechlorination of 2,6-dichlorophenol (2,6-DCP) and 2,4,6-trichlorophenol (2,4,6-TCP). The hydrodechlorination of these chlorinated phenolic compounds in a mixture of methanol and water was investigated using supported and unsupported palladium catalysts to yield lower chlorinated phenols or phenol. Various parameters were investigated such as catalyst concentration, ammonium formate concentration, effect of base addition and effect of temperature. During this study two methods of hydrodechlorination were also investigated such as hydride-transfer hydrogenolysis, using ammonium formate, and hydrogenolysis, using dihydrogen. These methods offer a mild treatment in terms of the reaction temperature with temperatures used below 800C. A comparison of the palladium catalyst systems using these methods also showed that Pd/C produced the best results in terms of the hydrodechlorination rate and the selectivity towards phenol. When the ammonium formate method was used, complete hydrodechlorination of both substrates was achieved in 1h of reaction time at a selectivity of 100 percent towards phenol. A comparison of the method using dihydrogen and Pd/C showed that the reaction rate and the selectivity towards phenol during the hydrodechlorination of 2,6-DCP were 87.92 percent and 93.30 percent. Similarly, the reaction rate and selectivity during 2,4,6- TCP hydrodechlorination were 63.77 percent and 70.57 percent. These results were achieved in a reaction time of 3 hours. A high catalyst loading increases the reaction rate at the expense of selectivity, due to the formation of cyclohexanone, formed during further hydrogenation of phenol. The formation of cyclohexanone was limited at high temperatures (ca. 800C) with none detected during the hydrodechlorination of 2,6-DCP and 0.19 percent during the hydrodechlorination of 2,4,6-TCP. Evaluation of the hydrodechlorination parameters showed that the catalytic efficiency of the Pd/C catalysts was inhibited as the reaction proceeded due to the formation of HCl as by-product. A significant increase in the reaction rate was achieved when the reaction was performed in the presence of an inorganic base, which neutralized HCl.

- Description: Type 2 diabetes mellitus is a chronic disease of pandemic magnitude, increasingly contributing to the disease burden of countries in the developing world, largely because of the effects of unhealthy lifestyles fuelled by unbridled urbanisation. In certain settings, patients with diabetes are more likely to have a healthcare encounter with a pharmacist than with any other healthcare provider. The overall aim of the study was to investigate the potential of South African community pharmacists to positively influence patient adherence and metabolic control in Type 2 diabetes. The designated primary endpoint was glycated haemoglobin, with the intermediate health outcomes of blood lipids, serum creatinine, blood pressure and body mass index serving as secondary endpoints. Community pharmacists and their associated Type 2 diabetes patients were recruited from areas throughout South Africa using the communication media of various nonstatutory pharmacy organisations. Although 156 pharmacists initially indicated interest in participating in the study, only 28 pharmacists and 153 patients were enrolled prior to baseline data collection. Of these, 16 pharmacists and 57 patients participated in the study for the full twelve months. Baseline clinical and psychosocial data were collected, after which pharmacists and their patients were randomised, nine pharmacists and 34 patients to the intervention group and 8 pharmacists and 27 patients to the control group. The sample size calculation revealed that each group required the participation of a minimum of 35 patients. Control pharmacists were requested to offer standard pharmaceutical care, while the intervention pharmacists were provided with a scope of practice diabetes care plan to guide the diabetes care they were to provide. Data were again collected 12-months postbaseline. At baseline, proportionally more intervention patients (82.4%) than control patients (59.3%) were using only oral anti-diabetes agents (i.e. not in combination with insulin), while insulin usage, either alone or in combination with oral agents was conversely greater in the control group (40.7%) than in the intervention group (17.6%) (Chi-squared test, p=0.013). Approximately half of the patients (53.8% control and 47.1% intervention) reported having their HbA1c levels measured in terms of accepted guidelines. There was no significant difference in HbA1c between the groups at the end of the study (Independent t-test, p=0.514). In the control group, the mean HbA1c increased from 7.3±1.2% to 7.6±1.5%, while for the intervention patients the variable remained almost constant (8.2±2.0% at baseline and 8.2±1.8% at post-baseline). Similarly, there were no significant differences between the groups with regard to any of the designated secondary clinical endpoints. Adherence to medication and self-management recommendations was similarly good for both groups. There were no significant differences between the two groups for any of the other psychosocial variables measured. In conclusion, intervention pharmacists were not able to significantly influence glycaemic control or therapeutic adherence compared to the control pharmacists.

- Description: The Kruger National Park (KNP) management has recently made considerable progress in enacting new policies to address biodiversity conservation and management challenges. However, the interlinkages among the new policies to support biodiversity conservation and management have not been evaluated, particularly the principles and approaches, and how these interact in terms of policy decision-making at the economic and political levels. This study seeks to evaluate the interlinkages among the new policies and how they affect one another, as an avenue to promote a more integrated and comprehensive policy implementation. These policies include the tourism policy, the elephant management policy, and the water provision policy. At policy-making level, the integration of these three policies enhances the possibilities for balancing and controlling the pressures exerted on environmental resources. At the implementation level, it offers a framework for the coordination of the interventions of the policies in space so as to recognise and capitalize on their synergies. Given the inevitably multifarious and departmentalized nature of policy formulation in the KNP, there is a need for the analysis of interlinkages amongst policies. The conceptual framework underpinning this study derives much from Briassoulis’ (2004) policy integration. The research utilizes both qualitative and quantitative research methods, and focuses on selected camp sites within the Park. The findings indicate that current procedures for tourism policy-making and implementation are weak, and little is done by way of impact assessment. This has been attributed to the lack of capacity at the KNP. The findings also reconfirm that policy-making is too fragmented. As a result, policy coordination and cooperation among park managers is weak. This study suggests that an environmental policy integration approach can lead to improved policy-making and implementation. Informed by the data collected from interviews, questionnaires and document analyses, a management framework has been developed to demonstrate how an integrated approach to Environmental Policy Integration (EPI) or management can help sustain the practice of wildlife tourism and support biodiversity conservation. It is concluded that greater realisation of integrated policy-making and implementation in the KNP can be achieved by establishing a formal coordinating office. However, a special feature of KNP policy-making is its widespread consultation system that can provide a fertile ground for enhancing EPI.

- Description: The study was premised on the truism that men have historically served in higher echelons of organizational management structures and women are under-represented. The principal objective was to explore the constraints faced by women in accessing higher leadership and senior management positions in public, private and non-governmental organisations in Zimbabwe. This study adopted the triangulation method, that is, qualitative and quantitative approaches. These mixed research methods, were upgraded by the feminist research methodologies, thereby making a contribution in the field of research. The study found out that the constraints that mostly hinder women from accessing leadership and senior management positions in public, private and NGOs were cultural practices, which represent levels of power and control that in turn hinder reforms; and women's socialisation into feminised roles. The study also found out that in most organisations, most females work under male leadership, and this traditional organisational culture, needs to be deconstructed and reversed in order to achieve gender equality. The study recommended for a human centric and integrated organizational management strategy for public, private and NGOs in Zimbabwe. The adoption of a human centric and integrated management approach should aim at gender equity and reduce women's under-representation. A human centred organizational culture has to be practiced, that would create organisational ethos that guide organizational management. An integrated organizational management approach should integrate all systems and processes into one complete framework, enabling people to work as a single unit, unified by organizational goals, shared vision and common values. The system should depend on a balanced mix of the masculine and feminine attributes. The approach should put its weight towards adoption of measures to attract, advance and empower women so as to benefit from their qualifications, experience and talent in a highly competitive environment.
