  • Description: The Drakensberg rock-jumper (Chaetops aurantius) is a high-altitude passerine endemic to South Africa and Lesotho, living along a highly disrupted portion of the southern Great Escarpment from the Drakensberg highlands in the north-east to the Sneeuberg in the west, above an altitude of 1500 m. Along with the Cape rock-jumper (C. frenatus), this genus provides one of the stronger faunal links between the floristic biomes known as the Drakensberg Alpine Centre (DAC) and the Cape Floristic Region (CFR). Despite this, there is a significant lack of information regarding the species. The great majority of information is based on incidental observation, and no dedicated study has been undertaken. I conducted a series of field excursions between January 2011 and November 2012 in order to explore the rock-jumper’s feeding ecology, diet, habitat usage and genetic diversity. By trapping the birds, I was able to mark them individually with unique colour ring-combinations, and pluck a tail feather for genetic analyses. Observational data reveal that birds living close to their lower altitude threshold (c. 1500 m) are strongly habitat specific, living in boulder fields dominated by grassy vegetation. However, in areas at higher elevations (c. 2000 – 2500 m) this restriction seemed to fall away, possibly as a result of farming practices in those areas – higher grazing pressure results in shorter grass and less foraging effort for the birds. They live in groups ranging from pairs to small family groups of up to twelve individuals and maintain year round territories. Territory defence takes the form of calling and displaying from a prominent rock or boulder and becomes particularly noticeable just prior to, and during, the breeding period. No colour ringed individuals were ever spotted in boulder fields outside from where they had been initially ringed. This, coupled with the behaviour of territory maintenance, suggests a strongly sedentary lifestyle. Genetic inferences are constrained by a small sample size (only 25 birds were caught), but results indicate that some genetic isolation is occurring – a single haplotype was exhibited in birds from across the southern Escarpment, while seven private haplotypes show that any genetic mixing is likely to be historical rather than current. Historical gene flow would most probably have occurred during the last glacial maximum (18 000 years before present), when the cooler, drier conditions which are currently restricted to high peaks would have been much more extensive, thereby decreasing the distance required for effective dispersal. This is in agreement with the observation results, concluding that although there has been movement of birds across the southern Escarpment in the past, it does not appear to be occurring currently. However, this does leave plenty of scope for further work, particularly in the genetic diversity of the species, and in expanding the ecological observations to include the breeding biology.

  • Description: Insulin resistance is a precursor to type II diabetes mellitus and in conjunction with dyslipidaemia, hypertension, and obesity, these abnormalities constitute the metabolic syndrome. Insulin resistance usually develops before these other diseases and therefore identifying and successfully treating insulin resistant patients may have potentially great preventive value. Insulin resistance, obesity, and subsequently type II diabetes mellitus have increased dramatically and have reached epidemic proportions. The incidence of diabetes, and in particular type II diabetes mellitus, is increasing in developing countries and throughout the world and this is mainly as a result of increasingly sedentary lifestyle and obesity in an aging population. The specific aim of this study was to explore and describe the effect of a 14-week strength-based resistance training programme on insulin resistance amongst individuals aged 25 to 68 years, who are pre-diabetic, have T2DM, and/or are overweight. The research approach used in this investigation was explorative, experimental, and quantitative in nature. The quasi-experimental design consisted of a pre-test and post-test for an experimental and comparison group who were chosen through convenience and snowball sampling. A total of 30 participants were involved in this study, 15 participants in each group. The following dependent variables were selected, namely: body weight; BMI; body composition; waist-to-hip ratio; total cholesterol levels; triglyceride levels; HOMA-IR; and muscle strength for upper and lower body. Pre-and post-test analysis was performed at the Biokinetics and Sport Science Unit, located at the Nelson Mandela Metropolitan University (NMMU). Blood samples of the participants were drawn by nurses at the Health Clinic at the Nelson Mandela Metropolitan University and these blood plasma samples were stored at the Department of Microbiology and Biochemistry at NMMU for later analysis of glucose and insulin. The experimental group trained three times per week for a period of fourteen weeks, performing strength training exercises with progressive increments in the intensity of the exercise. The control group remained sedentary throughout the intervention period. Analysis of the data was conducted utilizing descriptive and inferential statistics. Analysis of variance (ANOVA) was used as a hypothesis-testing procedure to evaluate the mean differences. The following dependent variables showed a decrease in mean values: body weight, body mass index, body fat percentage, waist minimum, cholesterol and insulin. However these differences in results were not practically and statistically significant. The following dependent variables showed an increase in mean values: hip maximum, arm relaxed, arm flexed, thigh circumference, glucose and HOMA-IR. However these results were not practically and statistically significant. The mean differences in the plasma insulin level, pre- to post-test, between both groups indicated that a significant difference (t = -1.77, p = 0.044) existed between them. Cohen‟s d revealed a value of 0.64, which indicates moderate practical significance. The only dependent variable which showed both statistical and practical significance was sum of skinfolds. The findings for sum of skinfolds revealed that the mean differences, from pre- to post-test, between both groups indicated that a significant difference (t = -2.30, p = 0.015) existed between them. Cohen‟s d revealed a value of 0.84, which indicated a large practical significance. Although the sample size was too small to indicate generalisations to the diabetic population as a whole, strength training should be furthermore explored as an alternative and successful modality in the existing range of options available to the health and exercise professional to address the needs of the person with T2DM. The researcher proposed that a bigger sample size be used for the experimental and control group, the intervention period increased as well as various differences related to frequency, intensity and duration of strength training could possibly result in significant changes.

  • Description: The objective of this thesis was to analyse the effect of the increasing popularity of global e-commerce on the South African legislative framework in respect of the taxation of non-resident enterprises, and to propose a possible solution for the taxation of e-commerce, taking into account previous theories. The methodology utilised comprised of a critical analysis of the legal rules relating to the taxation of a foreign entity's business profits by virtue of the application of the permanent establishment principle, its definition and evolution as a conceptual basis for taxation. Furthermore, an in depth evaluation of the various solutions that have already been proposed and, in some cases, implemented was undertaken. It was concluded that the application of the permanent establishment principle is wholly ineffective as a means to levy tax on the e-commerce business profits of a foreign entity as the principle relies too heavily upon a physical intermediary in the source state, whereas e-commerce transactions are conducted on the intangible trading platform of the Internet. In light of the numerous policy proposals advanced over the years, it was concluded that the most feasible and practical solution for the taxation of foreign e-commerce would be the imposition on a foreign entity in South Africa of a low withholding tax on the active business profits in excess of a pre-determined threshold. Key words: South African taxation; e-commerce; foreign business entity; permanent establishment; withholding tax

  • Description: Eutrophication of fresh water systems is one of the most important factors contributing to the invasion of fresh water bodies by water hyacinth, Eichhornia crassipes. The South American mite, Orthogalumna terebrantis, established on the weed in South Africa in the late 1980s, but the impact of mite herbivory on the weed has never been quantified. Water hyacinth was grown under low, medium and high nitrogen and phosphorus nutrient conditions and the effect of mite herbivory on the weed's growth was examined. Additionally, the impact of different mite herbivory intensities on the weed's photosynthetic performance was examined because herbivory may have more subtle effects on the plant than can be seen from changes in plant growth parameters. Water nutrient content had a great impact on plant growth, but growth was unaffected by mite herbivory in all levels of nutrients tested. Photosynthetic performance of water hyacinth leaves exposed to varying levels of mite herbivory was assessed by measuring net photosynthetic rate (A), leaf conductance (gl), transpiration rate (E) and intercellular CO2 concentration (Ci), and by measuring specific fluorescence parameters including maximal fluorescence (Fm), efficiency of photosystem II (Fv/Fm) and certain JIP-test parameters. Photosynthesis decreased as mite herbivory increased, but there was a positive correlation between gl, E and Ci, and the amount of leaf tissue damaged through mite feeding. The efficiency of photosystem II (PSII) decreased as mite herbivory increased, as seen in the altered fluorescence emission of mite-damaged plants, but this was not the consequence of decreased chlorophyll content. Feeding by O. terebrantis thus decreased water hyacinth photosynthetic rate and the light reaction performance, even at relatively low mite densities. These results show that the impact of a biological control agent on its host plant may not be obvious at a plant growth level, but may nonetheless affect the plant at a physiological level.

  • Description: In South Africa part of the cultural and religious beliefs of the African people is the use of traditional remedies to treat diseases. These remedies are obtained from medicinal plants (Steenkamp, 2003). One of the most frequently traded plants in the Eastern Cape is Hypoxis, commonly known as Afrika patat, or African potato. South African traditional healers instruct patients to brew the fresh Hypoxis corm as a tea and then ingest it (Steenkamp, 2006a). This prompted an investigation into the digestive stability of a traditionally prepared Hypoxis extract. The H. sobolifera extracts were digested using a simulated gastric/small intestinal digestion and their biological activity determined. The hot water H. sobolifera extract before digestion only showed cytotoxic activity against cancer cell lines at very high concentrations which are not likely to be achieved under normal ingestion circumstances. In Chang liver cells on the other hand, chronic exposure to the hot water H. sobolifera extract increased glucose uptake in amounts similar to that of metformin. On the negative side, the glucose utilization stimulation was lost due to the simulated digestion process. The significant inhibition of AGEs by hot water H. sobolifera extract (IC50 of 6.3 Ig/ml) is a very encouraging result as treatment in the management of diabetes. This activity was only slightly reduced by the in vitro digestion process. Also observed was enzyme inhibition activity by traditionally prepared H. sobolifera, with ∝-amylase being inhibited (IC50 of approximately 250 Ig/ml) and therefore preventing or limiting starch breakdown. From the DPPH results it was clear that H. sobolifera, even when digested, is a potent anti-oxidant (IC50 of 134.4 Ig/ml when undigested compared to 162.9 when digested with β-glucosidase added to stomach digestive step). HPLC and TLC experiments revealed that rooperol which has previously been thought to be the compound responsible for the anti-oxidant activity in Hypoxis extracts, was absent from the traditional extract of H. sobolifera and therefore cannot be the sole compound exhibiting anti-oxidant activity; other compounds such as phenolics may be contributing. The phenolic and flavonoid content results revealed very highconcentrations of these compounds in the traditionally prepared H. sobolifera extract. These compounds may therefore play major roles in all of the biological activities observed from treatment with Hypoxis spp. The ROS results yielded interesting and promising results. Using standard or traditionally prepared H. sobolifera extracts, activation of differentiated U937 cells with PMA was greatly enhanced by cotreatment with the extracts, while extracts on their own did not cause significant activation. Future studies should investigate this property of the extracts as a promising immune boosterThe HPLC results showed that hypoxoside was undetectable in the hot water traditional extract and the TLC anti-oxidant experiment proved that rooperol is not present in the hot water traditional extract after treatment with β-glucosidase. This indicates that neither one of the Hypoxis compounds previously believed to be responsible for the biological activities observed are present in the extract when prepared the traditional way. Therefore, the biological activities observed in this study can be attributed to other phytochemical compounds.

  • Description: It is argued that a lack of adequate legislation in pre-1994 South Africa resulted in inequality in the workplace and in society in general. The new democracy intended to address this by promulgated legislation and today the South Africa Constitutional and legislative provisions promoting equality are viewed as amongst the most progressive in the world. Conversely, this progressive legislation aimed to protect against discrimination, still seems to fail the very people it intended to promote and protect. The new legislation created awareness of the need for equality; the right of workers to employment – or at least to decent working conditions. The right to equality is accorded to everybody through the Constitution of South Africa. The Bill of Rights is based on the notion of equality before the law, and the prohibition of discrimination on various grounds. Despite this, the perception exist that persons with disabilities as a minority group are still being marginalised and are restricted in their right to exercise the right to participate and make a meaningful contribution to the labour market. This not only seems to be in contradiction with the Constitutional right to choose an occupation, but has wider social and economic consequences. The ethos of equality legislation is to ensure that the workplace is representative of the society we live in. It is understandable that labour as a social phenomenon is not only concerned with workplace related issues but with aspects encompassing the whole of the socio-political and economic scene. South African labour legislation drafted over the last two decades strives to align with the conventions and recommendations of the International Labour Organisations and in terms of the obligations of South Africa as a member state. However, the question prevails: is this legislation adequate to address the discrimination and inequality experienced by persons with disability? If so, why do statistics indicate such high unemployment amongst this group? Yet, there is a growing awareness that persons with disabilities represent enormous, untapped economic potential. According to the ILO report on The Right to Decent Work of Persons with Disabilities (1997), much has been accomplished in the international arena in recent years to improve the lives of persons with disabilities in the workplace. This treatise will attempt to evaluate the efficacy of South African legislation in the promotion and integration of persons with disabilities in the labour market.

  • Description: The effectiveness of harvesting slash treatments are questionable when wild fires, fuelled by post harvesting slash, burn out of control. In order to quantify effectiveness of various slash treatments, fire behaviour in Pinus patula and Eucalyptus macarthurii compartments in the Highveld area (Piet Retief) of Mpumalanga, South Africa, were assessed after application of five different post-harvesting slash treatments. Treatments included mulching, chopper rolling, windrowing, removal of slash (inter-windrowing) and broadcasting. Independent fuel and environmental variables were measured prior and during application of fire to the study areas and effects on fire behaviour were compared afterwards. Dependant fire behaviour variables such as the rate of spread, fire temperature and flame height were measured in respective slash treatment plots and compared. Results of the study indicated that fire behaviour assessed in mulched areas in both the P. patula and E. macarthurii compartments were significantly less intense when compared to fire behaviour in chopper roll, broadcast and windrow treatments. Fire behaviour in mulched plots compared favourably with areas where harvesting slash was removed (inter-windrow treatment). Comparisons between fuel loads of different treatments also indicated accelerated mineralization of organic material in mulched areas. Mulching of harvesting slash seems to be an effective method to restrict fire behaviour in post-harvesting compartments and should be considered as part of a fire management strategy.

  • Description: Perceived organisational support and organisational commitment plays a vital role in determining turnover intention. When employees feel that their organisation supports them levels of commitment can increase. Thus, employees feel more obligated because of favourable benefits such as organisational effectiveness and reduced turnover. The purpose of the present study was to investigate the effect perceived organisational support and organisational commitment have on turnover intention. The study followed a descriptive survey method. A questionnaire, measured on a Likert Scale was used to collect data from respondents. The sample comprised 98 academic staff at the University of Fort Hare and the response rate was 56.6 percent. The results indicated that perceived organisational support and organisational commitment are negatively and significantly related to turnover intention. The study also revealed perceived organisational support and organisational commitment on turnover intention did not account for a higher variance when put together, however moderate variance was found. Perceived organisational support in this study was identified as the most effective predictor of turnover intention. In addition to managerial implications and limitations of the study, direction for future research is also suggested at the end of this study. The findings of this study will help in terms of understanding the state of organisational commitment of academics and its relationship with their intentions to leave.

  • Description: Sports facilities increasingly feature amongst the most expensive development projects world-wide. One such facility includes world-class stadia. Such facilities tend to commit a considerably large amount of a country's public funds to the project. This public expenditure on new stadia, and the required public taxation, may be economically justified if the benefits from the new stadia outweigh the costs. 15 May 2004 saw South Africa winning the bid to host the FIFA 2010 Soccer World Cup tournament. This mega-event was played in 10 stadia across nine chosen host cities. Five of these stadia were newly constructed, while the other five needed upgrading. Both South Africa's national government and local governments of host cities bore the expenses of the new stadia construction and the upgrading to the existing stadia. This amounted to a total public expenditure of R13.5295 billion on the stadia alone. The Nelson Mandela Bay Stadium on the banks of the North End Lake in Port Elizabeth was amongst the five newly constructed stadia costing R1.7 billion. Many international studies have been conducted to assess the impact of new stadia on the economies of host cities. One particular aspect which has received a lot of attention as far as empirical research is concerned is the impact of stadia on residential property prices (Carlino & Couslon, 2004; Davies, 2005; Tu, 2005; Coates & Humphreys, 2006; Ahlfeldt & Maennig, 2007, 2010; Dehring, Depken & Ward, 2007; Feng & Humphreys, 2008, 2012; Kavetsos, 2010; Ahlfeldt, Maennig & Scholz, 2010; Kiel, Matheson & Sullivan, 2010; Ahlfeldt & Kavetsos, 2011; Coates & Matheson, 2011). The majority of the studies conducted have indicated that the presence of a new stadium in an area has a significantly positive effect on surrounding house values that decays with distance from the facility. As no study has yet been done in South Africa to investigate the impact of the announcement of the construction of new stadia on nearby residential property values, this study examines, by means of the hedonic pricing model, the effect of the announcement to construct the Nelson Mandela Bay Stadium on the banks of North End Lake on adjacent residential property values. The study period for this study was 2004 - 2006. This time period captured the stadium announcement effect. The residential properties in North End that were traded at least once during the period 2004 to 2006 made up the target population. According to the South African Property Transfer Guide (SAPTG), a total of 417 property transactions (excluding repeat sales) took place over the study period (2004 - 2006). The 417 transactions were deemed to be the size of the target population and a list of 100 property transactions were used as the sampling frame. As the study period was from 2004 - 2006, it was necessary to adjust the market prices to constant 2006 prices. For this purpose, data from the Port Elizabeth and Uitenhage section of the ABSA house price indices were used so as to eliminate any inflationary effects on the property values over the study period. The results of the study revealed that the stadium has a statistically significant positive effect on adjacent residential properties situated within a 1 200 metres radius from the stadium. The average owner of a residential property in North End would be willing-to-pay between R10 7898 and R11 704.6 to be situated 435 metres closer to the stadium.

  • Description: Historically the process of career development was thought of as occurring in adolescence and adulthood; however, the renewed emphasis on lifelong career development has led to a greater focus on the career developmental stage of childhood. The present research focused on the development and trialling of a research-based computerised career exploration tool, Growing-up: Children Building Careers™ (GCBC™) that can be used for early intervention in children‘s career development. The integration of developmental considerations within a career developmental context is of paramount importance, considering that child and career developmental theories share certain basic foundational principles such as the dual recognition of identifiable life stages and the resolution or accomplishment of associated tasks. The focus of the research is to provide access to a research-based tool that can assist learners with developing age appropriate career developmental skills. As the overview of education policy and existing programs will show, there are challenges in providing access to and improving the nature, level, and quality of career development services. Gaps in access to career development learning are particularly evident at the elementary education level. Furthermore it is clear that learners need to be at the centre of a radical rethink of careers services within a lifelong learning framework in order to ensure access to navigational tools throughout a lifetime of work and study transitions. Digital environments, such as the GCBC™, are tools that broaden and extend learning possibilities for children and appropriately designed digital environments can provide a vehicle that can take children further than they might travel unassisted. The research is divided into five phases and includes eight to ten year old children as participants. Phase one focused on the program design and pilot study (ensuring content validity and age-appropriate language use), while phases two to five focused on the fieldwork (i.e., pre –test, program exposure, post-test, and focus group discussions). The researcher made use of a mixed research design that combines both quantitative and qualitative research methods. The total sample consisted of 146 children between the ages of eight to ten years old. The control group had 72 children and the experimental group 74 children with a mean age of 8.74 years (SD = 0.63) for the total sample. The quantitative data collection entailed a pre-and post-test design with learners‘ career development measured with the Childhood Career Development Scale (CCDS) and their career awareness with the Revised Career Awareness Survey (RCAS). Qualitative data was collected in the form of two focus group discussions, which included a small sample of children from the experimental group, as well as insights gained from educators following the GCBC™ fieldwork. The quantitative statistical analysis included descriptive and inferential statistics which allowed the researcher to not only describe the research findings, but to confirm the effectiveness of the GCBC™ as an intentional career development learning program. Furthermore, the responses of the children and educators who participated in or witnessed the facilitation of the GCBC™ provided support for the GCBC™ as a meaningful career learning experience which can be successfully implemented in educational settings.

  • Description: Policy documents derived from the South African Constitution and the South African Schools Act clearly state that all learners are entitled to support, thus enabling them to reach their full potential. Support should be rendered effectively at school level within a well-established and functioning Institutional Level Support Teams (ILST). Institutional Level Support Teams (ILSTs) at primary schools within the Uitenhage District seem to be problematic, since parents, the school and the community do not realise that they should work interrelated with each other to enhance the effective establishment and functioning of the ILST. The main aim of this study is, therefore, to formulate guiding principles for the effective establishment and functioning of Institutional Level Support Teams. A qualitative research design using a phenomenological strategy was deemed appropriate for this study, as the researcher wants to gain a deeper understanding of the phenomenon under study. The researcher used a combination of convenience sampling, as well as purposive and judgement sampling. The sample group included educators, members of the Institutional Level Support Teams, Institutional Level Support Team co-ordinators, School Principals, community members and members of the District Based Support Team (DBST). Data were collected by means of semi-structured interviews, participant observations and questionnaires. Tesch’s eight step data analysis process was employed to identify possible common themes. The findings indicated that the stakeholder component of the social system representing learners, parents, schools and the community, do not provide sufficient support to learners experiencing learning challenges and therefore ILSTs are not functioning optimally presently.. Therefore the researcher provided supportive guiding principles to parents, the school and the community, for the effective establishment and functioning of the ILST, based on Bronfenbrenner’s eco-systemic theory, which is the theoretical framework of this study.

  • Description: Health and education are two important aspects of human capital and form the basis of an individual’s economic productivity in any country. In South Africa, hunger and malnutrition continue to hamper the health, quality of life and survival of school going children such that some children drop- out of school due to these socio-economic problems (Tomlinson,2007:2). The introduction of previous School Feeding Schemes to address the question of hunger and poverty within schools was mostly left in the 1980’s and 1990’s to charitable and Non-Governmental Organizations such as Operation Hunger and ITHUBA (Swartz, 2009:38). According to Perlman (1993:14) South Africa’s track record of child deaths was more than double that of any other country of similar income levels worldwide, due to the apartheid government deserting its responsibility of feeding the nation. The White Paper for the Transformation of Health System (1997: 125) had also stated that improving nutrition within the rural schools is an imperative and a sound economic investment which is politically rewarding. Nelson Mandela (1996:8) once said “Our children are our nation’s future. Prospects for development are seriously undermined by the kind of large scale deprivation of children that South Africa has experienced. On the other hand investing in their health, nutrition and education not only improves our children’s quality of life – the gains reverberate into the future generations. ” From April 1994, through the Reconstruction and Development Programme (RDP) the Government of National Unity under the leadership of Dr. Nelson Mandela identified the area of school feeding as a policy prime concern in redressing the imbalances and inequities of the past governments. Another initiative to redress the inequities of the past, was through the programme of Poverty Reduction which manifested itself in lack of income, lack of education and skills, lack of access to services and amenities and lack of ownership of land and housing (Public Service Commission, 2007.

  • Description: The world has become more competitive, complex and unpredictable, and this process is continuing. Evolution is taking place resulting in organisations being pushed by strategies and pulled by increasingly assertive customers who demand more accountability and responsiveness (Kartte, 2010). In order to remain competitive in this changing world, many organisations, even financial institutions have adopted Lean principles in order to eliminate waste, reduce cost and streamline everyday processes (Spear, 2012). There have however been a number of challenges that have prevented financial institutions from implementing Lean principles successfully. The primary objective of this study is to improve the effectiveness of Lean principles within a specific financial institution. More specifically, this study will identify the effectiveness of successfully implementing Lean principles at a financial institution by investigating the influence of employee knowledge, understanding and skills, communication, motivation and ownership from management, organisational culture and the impact of trade unions in organisations as mentioned in the problem statement above. Convenience sampling was used to select a sample of sixty eight (68) employees within the specific financial institution. The sample was stratified to include senior managers, managers, team leaders and lower level employees. Questionnaires were distributed personally to the focus groups from the above categories.

  • Description: The study was aimed at investigating the effectiveness of social support mechanisms provided to HIV and AIDS orphans in Tembisa, Gauteng Province. An interview guide was designed and it guided the in-depth interviews with HIV and AIDS affected and infected orphans. In addition, a focus group was run with the social workers and the children‟s caregivers. Empirical findings gathered were based on the qualitative information from the participants. The findings indicated that social support systems were effective although there were various challenges facing their smooth running. Firstly social support provided to orphans is mainly provided by caregivers, social workers, schools and the government. Secondly for some, the support is not entirely enough to help them cope with life. The minority of the orphans indicated that they were not even aware that they were orphaned. The study therefore recommends that social workers and caregivers be trained on how to be effective social support systems for HIV and AIDS orphans. Furthermore psycho-social support groups need to be more informational and inclusive of HIV and AIDS orphans.

  • Description: This study examines the effects of conflict on socio-economic development. It focuses on the ongoing political conflict in the Nelson Mandela Bay Municipality due to national political factionalism that has negatively affected service delivery. Political conflict led to the absence of the municipal manager from 2009, impacting the administration of the Metro. Since that time, no municipal manager has held office for more than four months. The municipal manager’s job is crucial to the operation of the Metro, including the allocation of funds required for service delivery. Service delivery has therefore been negatively affected by the conflict, with waste removal being particularly neglected. This has been prevalent in areas such as New Brighton and Motherwell, which will be the primary focus of this treatise. This study found that, as a consequence of the situation in the Metro community members have become indifferent to political affairs. However, they still seek change and have faith that their livelihoods could be improved.

  • Description: This study investigated the effects of gender based violence on children in the Zimunya community of Mutare in Zimbabwe. A qualitative approach was used to gather data, thus thirty children from thirty households from three wards were interviewed and three focus groups were conducted with women from the three wards of Zimunya. The outcomes of the research reveal that gender based violence have negative effects on children who are affected physically, socially, emotionally and psychologically. In other words, gender based violence impacts negatively on the development of the affected children. In the areas under study, domestic violence was identified as the most prevalent types of violence experienced by children in these communities. This is in spite of the fact that there are many services that are provided to protect children and their mothers from violent situations. The role played by support service groups cannot be undermined as they contributed to the reduction of violence in some homes. It is thus concluded that, in as much as services are provided by both government and non-government organizations to the victims of violence, many affected people were not utilizing them fully. Additionally, some research participants showed a certain level of confusion in distinguishing between services provided for children from those provided for women. This study therefore recommends that awareness campaigns should be carried out in many communities in Zimbabwe so as to inform women and children about the availability support services, what they are meant for and for whom. Additionally, the gender violence topic should also be introduced in primary and secondary school syllabuses of Zimbabwe so as to make all children aware of their rights and responsibilities as they grow up.

  • Description: The research attempts to investigate the effectiveness of coordination in the State Ministry of Cabinet Affairs (SMCA), Jonglei State government, South Sudan. The objectives of the study were to identify coordination functions of the state Ministry of Cabinet Affairs, challenges and its role in promoting ethics and good governance in service delivery in Jonglei State. Quantitative and qualitative data was collected from a sample of twenty one respondents which included the State Deputy Governor, Directors of SMCA and Secretariat through questionnaires and interviews. This explored the functions; roles; and its organizational hierarchy which promotes ethical delivery of services and good governance. The study further discusses the levels of the implementation processes and the possible challenges facing SMCA. The results of the study reveal that the SMCA lacks qualified staff, unclear job descriptions and as a result it impinges on coordination and implementation of strategic plans and service delivery within the directorates. The study therefore recommends that for effective and efficient service delivery in promoting ethics and good governance, training of the human resource, recruitment of competent staff, clear job descriptions, regular performance appraisal and effective communication among others are paramount. The study further recommends that gender equality and equity should be addressed in order to meet the Millennium Development Goals (MDGs) in the community.
