- Description: Migrant remittances have been cited as one of the most rising forms of development financing. Migration-development scholarly debates have often made comparisons between migrant remittances and some of the most popular forms of development financing such as development aid. The development-migration debates have often contended that migrant remittances are fast growing and surpassing the popular forms of development financing. This study sought to examine the developmental role of migrant remittances in the rural district of Tsholotsho in Zimbabwe. Given that there are millions of Zimbabwean migrants working in South Africa, the study sought to examine the possible use of migrant remittances in the creation of sustainable livelihoods. In addition, the study focused on examining the skills and opportunities that are necessary in the creation of an enabling environment for investment as well as assessing the multiplier effect that result from the inflow of migrant remittances within the local economy. The study followed a mixed methods methodological approach wherein a quantitative survey and qualitative in-depth interviews were used to gather data. The findings of this study revealed that migrant remittances are central in the livelihoods of poor people in Tsholotsho and they have potential to create sustainable livelihoods. While skills and opportunities to drive entrepreneurial activity exist, there is need to deal with structural barriers in order to create an enabling environment for the creation of sustainable livelihoods through savings and investment. The study recommends the prioritization of education, improved access to the credit system and the development of cooperatives. These could assist in achieving sustainable livelihoods through migrant remittances.

- Description: This study investigated the synthesis of rhenium(I) and rhenium(V) complexes with a variety of multidentate NS, NSO, NO and SO-donor ligands. It also investigated the synthesis of dinuclear dihalogeno- and trihalogeno-bridged rhenium(I) complexes based on the fac-[Re(CO)3]+ core. The reactions of hydrated folic acid with [Re(CO)5X] (X = Cl, Br) were studied, and the complexes [Re(CO)3(H2O)3]+[Re2(μ-X)3CO)6]−.5H2O [X= Br (1), Cl(2)] were isolated. The reaction of orotic acid potassium salt [Re(CO)5Br] was performed, and the complex [Re2(μ-Br)2(CO)8] was isolated. The reaction of bis(piperidin-1- yl)methanone with [Re(CO)5Cl] followed by recrystallisation of the resulting precipitate in dichloromethane/acetontrile resulted in the complex [Re2(μ- Cl)2(CO)6(MeCN)2]. The X-ray crystal structures show that all these complexes display a distorted octahedral geometry around the central rhenium atoms. The reactions of aroylhydrazone-based ligands such as 3-((pyridin- 2yl)methyleneamino)-2,3-dihydro-2-pyridin-2yl)quinazolin-4-(1H)-one (Hppq) and N-(di(pyridin-2-yl)methylene)benzohydrazide (Hdpmb) with [Re(CO)5Cl] were studied and led to the formation of the complexes [Re(CO)3Cl(Hdpmb)] and [Re(CO)3Cl(Hppq)]. The Hdpmb and Hppq coordinated to the fac-[Re(CO)3]+ core as neutral bidentate chalates via the pyridinic nitrogens (for Hdpmb) and via imino and pyridinic nitrogens for Hppq. The X-ray crystal structures show that the geometry around the rhenium in both complexes is a distorted octahedral. The treatment of the dithizone (H2dz) ligand with rhenium(V) precursors containing a triphenylphosphine group (PPh3) led to the decomposition of dithizone. The decomposition product reacted with the triphenylphosphine group and generated a new ligand triphenylphosphazeno-N-phenylmethanethiohydrazide (H2L). The reaction of trans-[ReOX3(PPh3)2] (X = Cl, Br) with dithizone (H2dz) led to the complex [ReO(dz)2][ReO(HL)2]. The reaction of trans-[ReOI2(OEt)(PPh3)2] with H2dz led to the same product. The reaction of cis-[ReO2I(PPh3)2] with H2dz in methanol led to [ReO(dz)2][ReO(HL)2](MeOH)2 in which methanol bonded to HLvia hydrogen bonds. The H2dz was doubly deprotonated and coordinated to the [ReO]3+ moiety via a thiolate sulfur and deprotonated hydrazinic nitrogen to yield [ReO(dz)2]−, while the H2L was singly deprotonated and coordinated to [ReO]3+ moiety via the neutral sulfur atom and deprotonated hydrazinic nitrogen to yield [ReO(HL)2]+. The X-ray crystal structure show that in both [ReO(HL)2]+ and [ReO(dz)2]−, the rhenium atoms are five-coordinated and adopt a distorted squarebased pyramidal geometry. The reaction of thiosemicarbazones such as salcylidene-4- phenylthiosemicarbazide (H3salpt) with cis-[ReO2I(PPh3)2] was investigated and led to the complex [ReO(Hsalpt)(H2salpt)]. The X-ray study reveals that Hsalpt is present as a tridentate chelate coordinating via the thiolate sulfur, imino nitrogen and phenolic oxygen, while H2salpt coordinates as a bidentate chelate via the thiolate sulfur and imino nitrogen atoms. The geometry around rhenium is distorted octahedral. The coordination mode of the benzoylthiourea derivatives 4-tert-butyl-N- (diphenylcarbamothioyl)benzamide (Htpb) and N-(diethylcarbamothioyl)benzamide (Heb) to the [Re2O3]4+ and fac-[Re(CO)3]+ cores were investigated. The reaction of [Re(CO)5Cl] in presence of sodium acetate with Htpb led to the dimeric complex [Re(CO)3(tpb)]2 in which the tpb coordinated to the fac-[Re(CO)3]+ core via the ketonic oxygen and bridging thiolate sulfur. The same reaction with Heb led to the monomeric complex [Re(CO)3(eb)(Heb)], in which the eb coordinates to the fac-[Re(CO)3]+core via thiolate sulfur and ketonic oxygen with Heb binding via the neutral sulfur atom. The reaction of Heb with cis-[ReO2I(PPh3)2] at room temperature with excess of sodium acetate led to the dimeric complex (μ-O)[ReO(eb)2]2 in which Heb is present as a monoanionic (deprotonated) bidentate with coordination through the thiolate sulfur and ketonic oxygen.

- Description: This study applied ecological niche models to determine the potential invasive range of Nile tilapia, Oreochromis niloticus, with a particular focus on river systems in southern Africa where it is now established and spreading. Computational tools such as niche models are useful in predicting the potential range of invasive species, but there are limitations to their application. In particular, models trained on native records may fail to predict the full extent of an invasion. This failure is often attributed to changes in either the niche of the invading species or the variables used to develop the models. In this study, we therefore evaluated the differences in the predictive power of models trained with different environmental variables, the effect of species range (native vs. introduced) on model performance and assessed whether or not there is evidence suggestive of a niche shift in Nile tilapia following its introduction. Niche models were constructed using Maxent and the degree of niche similarity was assessed using Schoener‘s index. Null models were used to test for significance. Model performance and niche conservatism varied significantly with variable selection and species range. This indicates that the environmental conditions available to Nile tilapia in its native and introduced ranges are not congruent. Nile tilapia exhibited broad invasive potential over most of southern Africa that overlaps the natural range of endemic congenerics. Of particular concern are areas which are free of exotic species but are now vulnerable due to the promotion of fish introductions mainly for aquaculture and sport fishing.

- Description: From human to human(e) is an exploration of ways of coming to understand what it means to be(come) human and to belong (Vanier, 2003) while living and working as an educator in a disadvantaged community. In this sense, the purpose of this dissertation is the exploration of understanding what it might mean to be a ‘Foundation Phase’ (Primary/Elementary School) educator in a context of constructed poverty and disadvantage (Swanson 2004), thereby contributing to the field of education in this area, whilst embracing a practice of freedom and fostering apertures of hope and transcendence. This reflexive, rhizomatic narrative journeying (ibid) attempts to reach out to humanity via an interdisciplinary and arts-based approach that attempts to address concerns of inequity and pedagogical in-access and evokes the spiritual, emotive and philosophical in drawing attention to the ethical irresponsibility and socio-spiritual repercussions of ignoring social disadvantage in education. It includes inherences and impressions of humaneness in education. It seeks both introspection and insight into what ‘the human condition’ might mean to a just and robust education of children. In this sense, it is a personal inquiry as reflexive narrative journeying (ibid) based on twenty seven years of teaching in a primary school in a vulnerable and economically-impoverished community in the province of KwaZulu Natal in South Africa. As a writing-as-inquiry journeying, I engage with ‘critical rhizomatic narrative’ methodology (Swanson, 2004) as it resonates with the explorations of lived experiences that pertain to emotions, feelings, values and spirituality and because it enables a process of seeking what it might mean to be(come) human(e). This study is a philosophical rhizomatic narrative rendering which is an approach to(wards) understandings of personal growth and spirituality through understanding the various emergent journeys of life and the meanings that we can elicit from them to become more human and thus more humane.

- Description: This research study aimed to examine how the identity of ' Muslim' people is constructed in British print media today, and whether or not these constructions promote or undermine a xeno-racist project. The research draws on the idea that identity is partly constructed through representation, with an emphasis on how language can be used to construct and position people in different ways. Using a social constructionist paradigm, the study further considers the role that print media has in providing a discursive field within which the construction and reproduction of racist attitudes and ideologies in contemporary global society can take place. Sixty-five newspaper articles were selected from the online archives of British newspapers, The Guardian and The Daily Telegraph using systematic random sampling. These were analysed using the six stages of Foucauldian discourse analysis outlined by Carla Willig. To provide a more fruitful account, the analysis also incorporated the methods of Potter and Wetherell whose focus is on the function of discourse, as well as van Langenhove and Harre's focus on subject positioning, and Parker's use of Foucauldian analysis which looks at power distributions. The analysis revealed that Muslims are discursively constructed as a direct politicised or terror threat, often drawing on discourses of sharia law, and Muslim-Christian relationships. They are also constructed as a cultural threat, drawing on discourses of isolation, oppressed women, the veil/headscarf, identity, visibility and integration. The analysis also showed some variation in constructions, and these extended from the racialization of Muslims to showing the compatibility between Islamic and western values. This study discusses the form these different constructions take and the possible implications these constructions might have in contributing toward a prejudiced and largely negative image of Islam and Muslims.

- Description: In the face of rapid urbanization and global climate change, urban trees and green spaces (UTGS) can contribute to the welfare of people and the urban environment. Urban trees and green spaces can assist to address urbanization challenges related to environmental degradation. While functions of UTGS have been well documented in the developed world, they have not yet received full attention in much of sub-Saharan Africa. Consequently, UTGS are under threat from urban development and fragmentation. Notably, the problems associated with UTGS also fall into the governance realm and indications are that poor governance and management of UTGS can negatively influence the potential benefits of UTGS to local people and the environment. This formed a basis for this research. The main objective of the study was to determine the current governance and management approaches to UTGS in South Africa. Through document search and review, the study determined the governance institutions influencing UTGS at national level and at provincial level (in the Limpopo and Eastern Cape Provinces). Face-to-face and online survey methods were used to determine the extent to which 28 local municipalities had adopted planned, systematic and integrated management of UTGS. The snowball approach was used to determine the key actors involved in UTGS activities and interviews were conducted to establish the roles and capabilities of these actors. A total of 540 household interviews were conducted to determine the institutional factors influencing local peoples’ ability to access, plant and use UTGS. The findings of the study showed that UTGS have not been adequately covered in existing governance institutions and practice at national and provincial levels. Local government municipalities were not managing their UTGS in a planned or systematic manner due to constraining factors such as insufficient funds, insufficient personnel, lack of equipment and lack of political support. Only 7.1 % of the surveyed municipalities had an urban tree management plan and an estimate of the urban tree stock; 32.1 % had tree policies; 28.6 % had tree bylaws; 21.4 % had tree planting schedules; 10.7 % had tree maintenance schedules and only 3.6 % had tree inspection schedules. Key actors involved in UTGS activities differed among levels of government. The actors included national and provincial government departments, local government municipalities, Non-Governmental Organizations, private sector companies and local volunteers. Most of the actors, however, either planted trees or provided tree seedlings to municipalities and the local people. Tenure security was a key institutional factor affecting peoples’ ability to plant, use or even remove trees from their residential plots. The same applied to trees in the streets and public parks. Whereas most respondents did not require permission to plant (79.8 %) or remove (75 %) trees on their residential plots, a majority of them required permission to plant and remove trees from streets (over 70 %) and public parks (over 80 %). However, with regard to planting and removing urban trees in public open spaces, 54% of the respondents indicated that permission was not required suggesting a lack of clarity among local residents on the issue. Overall, the findings of this study indicate that there is no political recognition and support for UTGS at almost all levels of government. This has resulted in the lack of incorporation of UTGS in urban planning and development and has caused UTGS to receive limited funding to permit planned and systematic management. Given the current rates of urbanization and urban development, the lowly prioritised UTGS are vulnerable to exploitation. To conserve UTGS and promote their potential contribution to local people and the environment, UTGS must be recognized and placed on political and development agendas. There is a need to develop national guidelines for UTGS management, assess the extent of the urban forest resource in local municipalities, clearly define the roles and capabilities of different actors, integrate UTGS in the urban planning and development system, and most of all seek to involve the local people in overall management and governance of UTGS.

- Description: In the face of rapid urbanization and global climate change, urban trees and green spaces (UTGS) can contribute to the welfare of people and the urban environment. Urban trees and green spaces can assist to address urbanization challenges related to environmental degradation. While functions of UTGS have been well documented in the developed world, they have not yet received full attention in much of sub-Saharan Africa. Consequently, UTGS are under threat from urban development and fragmentation. Notably, the problems associated with UTGS also fall into the governance realm and indications are that poor governance and management of UTGS can negatively influence the potential benefits of UTGS to local people and the environment. This formed a basis for this research. The main objective of the study was to determine the current governance and management approaches to UTGS in South Africa. Through document search and review, the study determined the governance institutions influencing UTGS at national level and at provincial level (in the Limpopo and Eastern Cape Provinces). Face-to-face and online survey methods were used to determine the extent to which 28 local municipalities had adopted planned, systematic and integrated management of UTGS. The snowball approach was used to determine the key actors involved in UTGS activities and interviews were conducted to establish the roles and capabilities of these actors. A total of 540 household interviews were conducted to determine the institutional factors influencing local peoples’ ability to access, plant and use UTGS. The findings of the study showed that UTGS have not been adequately covered in existing governance institutions and practice at national and provincial levels. Local government municipalities were not managing their UTGS in a planned or systematic manner due to constraining factors such as insufficient funds, insufficient personnel, lack of equipment and lack of political support. Only 7.1 % of the surveyed municipalities had an urban tree management plan and an estimate of the urban tree stock; 32.1 % had tree policies; 28.6 % had tree bylaws; 21.4 % had tree planting schedules; 10.7 % had tree maintenance schedules and only 3.6 % had tree inspection schedules.

- Description: The genus Aloiampelos Klopper & Gideon F.Sm., previously treated as Aloe L. Ser. Macrifoliae (Sect. Prolongatae), comprises seven species with barely succulent leaves that are popularly known as rambling, scrambling or climbing aloes, because they make use of surrounding trees and shrubs for support. The rambling aloes are centered in the Eastern Cape but some species have disjunct distributions in the Western Cape and KwaZulu-Natal. Many are widely used in gardens and landscaping. With their rambling habit and weakly succulent leaves, the genus is widely considered to be an old lineage among alooid genera. Species concepts within the genus remain contentious, with disagreement amongst taxonomists with respect to the recognition of some taxa at the rank of variety. Morphology, historical taxonomy, palynology and phylogenetics of the genus were investigated. The occasional presence of minute cilia on the sheathing leaf bases and distinct lineation of the leaf sheaths of Aloiampelos tenuior var. decidua and Aloiampelos tenuior var. rubriflora were the most important outcomes of the morphological study. The pollen grains of all species studied were very similar in grain shape and exine surface pattern, with only minor differences in grain size. Ordination analyses showed that grain length and muri length were useful at the infraspecific level, with Aloiampelos tenuior “orange” separating clearly from the other varieties. Pollen morphology was therefore not informative as a taxonomic character at species level when used in isolation, but may be useful when used in conjunction with other characteristics. Preliminary analyses of two plastid barcoding regions (matK and rbcL) and nuclear ITS have confirmed that Aloiampelos is monophyletic. These barcoding markers were not informative in assessing the species boundaries among the closely related taxa in the genus and morphological assessments were therefore used to elucidate relationships at the species rank. A key is given for the genus, integrating the findings of the study.

- Description: Rural development can be supported by information and knowledge which are key strategic resources for socio economic development. ICTs enable the facilitation and communication of information between remotely dispersed individuals or groups and more developed regions. While it has become common place that ICTs possess capabilities to potentially support rural development, the concept of ICT for development (ICT4D) is still fraught with challenges and barriers, which impede the success and sustainability of ICT4D projects. It is therefore essential to evaluate rural ICT projects, as such an analysis may aid in revealing information related to the need, effectiveness, impact, and sustainability of these projects. This research seeks to further the implementation and exploration of the Rural ICT Comprehensive Evaluation Framework (RICT-CEF), through the application of the Process Assessment domain in a real life rural ICT project environment. The RICT-CEF framework consisting of 7 evaluation domains has the primary objective of evaluating rural ICT projects from their inception stages to post implementation. A process assessment seeks to determine whether or not a rural ICT project is operating to implement its intended functions in the intended way specified in the projects plan. Such an assessment is invaluable to a comprehensive evaluation. Evaluation questions for a process assessment are centred around critical themes of project performance. Critical themes are aspects of a programme or projects implementation which must be enacted in order to achieve desired project outcomes. This research study is aimed at identifying critical themes of process assessment relevant to rural ICT4D projects. To identify critical themes, assessment approaches on social programme process assessments, evaluation of information systems in use, and rural ICT4D project evaluation case studies are comparatively analysed. Fourteen assessment approaches from these three categories are selected based on criteria. To analyse selected assessment approaches, a template is created based on the research questions, foundational literature on process assessment and identified challenges applicable to process assessments of rural ICT4D projects. Comparing and contrasting critical themes from these assessment approaches highlight critical themes essential to assess in the iterative implementation phase of rural ICT projects. Accentuated critical themes include, service utilization, organizational function and external project factors. These themes, along with suggested guiding principles from literature for conducting process assessments enable the creation of a framework for conducting process assessments of rural ICT projects. The framework is labelled "the Rural ICT Project Process Assessment Framework (RICTP-PAF)". The application of the RICTP-PAF in a real life rural ICT project through a design science case study provides lessons learned (suitability and shortcomings) from applying the framework. This essentially demonstrates the sensitivity of the RICTP-PAF to rural contexts in which it is implemented in. For instance, the implemented prototype of the RICTP-PAF reveals that the framework places a great deal of emphasis on rural beneficiary perspectives. A practice which has been lacking in such evaluation exercises. Furthermore, the guiding principles elucidated, bring to mind best practices to deal with issues such as stakeholder conflict, unreliable data elicitation and unethical assessment practices. The RICTP-PAF represents a fundamental tool for process assessments of rural ICT projects, and may be adopted and customized to various rural ICT project contexts in developing countries.

- Description: On September 8 2000, world leaders gathered at the United Nations summit and resolved to help citizens in the world's poorest countries to achieve a better life by the year 2015. This resolve was outlined in the Millennium Development Goals that were subsequently published with goals 4, 5 and 6 specific to healthcare. The integration of ICT‘s in the remote delivery of services has opened new avenues from which centralised, scarce resources can be accessed remotely for the benefit of the general population. Telemedicine has made great strides in the developed world with remote populations benefiting from the improved access to healthcare. In the Eastern Cape Province of South Africa, the sub-field of teleradiology has shown promise for enabling the wider delivery of specialist services. However, in resource constrained settings such as developing countries, telemedicine has had limited success and as a result, the equitable access to healthcare for remote populations remains inconceivable. This is exacerbated by the migration of healthcare professionals both domestically and internationally. The public sector has suffered the most with acute staff shortages in the public healthcare institutions, more so in rural and remote areas. This study identifies the prevailing challenges posing as barriers to the effective use of telemedicine services in the Public health sector in resource constrained settings and provides recommendations and guidelines aimed at facilitating the adoption and effective use of telemedicine. Challenges are identified from literature and from the first person accounts of specific role-players who are directly involved with telemedicine in their respective institutions. Participants are drawn from institutions offering telemedicine services within the Eastern Cape Province of South Africa. Challenges identified from literature are collated with those identified from the participant interviews to provide a concise list of factors that is used as input to the recommendation and guideline development process. The results thus far point to an enthusiastic environment coupled with a semi-capable infrastructure but however hampered by staff shortages and a general lack of support structures and propulsion mechanisms to adequately encourage the wider use of telemedicine. The proposed guidelines aim to address the challenges at the different role-player levels.

- Description: This study explores the potential for critical pedagogical innovation to expand student learning activity, meaning making and learning agency of first year undergraduate students. The study is located in a larger critical project. Rather than looking to support ‘unprepared’ students to better adapt to the current culture of higher education, the larger critical project looks to the generative potential of new students to elaborate the structure of higher education itself over time. The study emanates from a process of reflective self-critique of one higher education institution in South Africa serving a student population with little access to educational advantage. The emerging critique was located at the interface of institutional practice, student learning activity and the meaning making processes mediating the two domains. This critique gave birth to the pedagogical innovation at the centre of this study. The pedagogical innovation took the form of an activity system, with three sets of pedagogical tools mediating the system: tools to expand the learning practice of students, symbolic tools to expand the critical meaning making toolkit available, and tools designed to build a new learning community better aligned with interactive learning activity. This study is an intervention case study, theoretically grounded in the work of activity and socio-cultural theorists. The pedagogy was embedded within a semester long credit-bearing core course for entering first year students. The study follows the experience of the 652 students participating in the 2010 pilot experience. Upwards of 70% of students suggest that their reading (76%) and writing (71%) practice had changed by the end of the course. Over 80% indicated that the course made them better readers (85%) and writers (84%.) Students suggest that they read and write more and enjoy reading and writing more. They suggest that as motive expanded, activity of reading and writing expanded, complimentary activity expanded (e.g. expression and critical engagement), and participation across a number of domains expanded. Students with less historical access to educational advantage made stronger claims about the pedagogical toolkit than students with more access to educational advantage. This study suggests that under the right conditions, critical pedagogy focusing on student learning activity and meaning making can expand learning practice and meaning making of first year undergraduate students, contributing to an expanding claim on learning agency. It tentatively suggests that this type of learning architecture is well aligned for appropriation of students with less access to historical socio-educational learning privilege, but remains sensitive to the situated nature of historic disadvantage (for example, in campus sites.) The study points to the specific potential of three toolkits: toolkits to mediate expanded learning activity, toolkits to expand meaning making, and toolkits designed to directly reconstitute the learning community itself. The study concludes by extracting some lessons for critical pedagogical innovation serving first year studies into the future. It points to the importance of the domain of learning activity and meaning making, and suggests the kind of changes within the culture of higher education required to better unleash innovation in this area. It points to the generative potential of methods that better combine students and lecturers within pedagogical innovation processes. The study concludes by pointing to the relatively unoccupied area of critical research, whereby the work to expand the learning activity of first year students is aligned to the potential of students to elaborate the structure of higher education itself over time. The study points to three specific research areas: research building stronger pedagogical tools for first year students; research to better understand the critical meaning making project of students; and research to better understand the transformation of the pedagogical inheritance within higher education.

- Description: An electricity demand profile is a graph showing the amount of electricity used by customers over a unit of time. It shows the variation in electricity demand versus time. In the demand profiles, the shape of the graph is of utmost importance. The variations in demand profiles are caused by many factors, such as economic and en- vironmental factors. These variations may also be due to changes in the electricity use behaviours of electricity users. This study seeks to model daily profiles of energy demand in South Africa with a model which is a composition of two de Moivre type models. The model has seven parameters, each with a natural interpretation (one parameter representing minimum demand in a day, two parameters representing the time of morning and afternoon peaks, two parameters representing the shape of each peak, and two parameters representing the total energy per peak). With the help of this model, we trace change in the demand profile over a number of years. The proposed model will be helpful for short to long term electricity demand forecasting.

- Description: The need for programme management to align, coordinate and manage a portfolio of construction projects to deliver benefits that would not be achievable if the projects were managed independently in a turbulent economic environment, limitations of project management, and increasing stakeholder expectations cannot be over emphasised. In the construction industry, the implementation of programme management has been bedevilled with major challenges of which the North West Department of Public Works (DPW) CAPEX programme is no exception. The CAPEX programme has been noted for delivering fewer infrastructure projects as planned in terms of budget, time, and other expectations. The research documented in this treatise thus examined the existing programme management approach of the North West DPW CAPEX programme with respect to generally accepted standards and practices. A mixed research approach was used to identify problems such as delays in payment of works, poor reporting standards, improper planning of works, procurement difficulties, and inadequate management structures. The results point to excessive bureaucratic processes, improper information management systems and lack of commitment and ownership towards government works as the major underlying causes of the programme predicaments. Dogmatic implementation of government’s black economic empowerment policies and inadequate in-house capacity were also contributing factors. The research findings imply that effective processes should be laid for prompt payment of works certificates and invoices. Improved reporting standards and proper planning of the programme as a whole and its constituent projects is necessary for the attainment of stipulated goals. In particular, it is crucial to ensure that adequate management considerations in terms of capacity, infrastructure, structures and expertise are put in place while the procurement processes should be continually reviewed for programme success purposes.

- Description: Middle managers are important role players in organisations today. They are the link between the executive and the employees of organisations. Managers must ensure that the employees under their supervision fulfil their duties and responsibilities in the execution of their tasks, in order that the organisation achieves the strategic goals as set by the executive. For employees to perform at their peak and to ensure continual motivation, employees should find themselves in a motivated work environment. Managers are key to establishing this motivating climate; however they are only able to do this if they have sufficient authority to motivate their subordinates. Managers must not only have the authority, but they must also have the leadership skills and capacity to motivate. The question which forms the base of this research is whether managers are authorised and equipped to motivate their subordinates. The research topic fell within the quantitative paradigm with data being collected through the use of a questionnaire, which was distributed via electronic means to a sample of the population. The sample was selected using a non-random sampling method. The results were analysed and interpreted to ascertain if they aligned with the theory. The Respondents confirmed that motivation is deemed important which is the responsibility of managers to motivate their subordinates. The organisations in which the managers work should enable them to reward and recognise the employees. It was clear that the authority to reward and recognise is still limited in organisations, which creates substantial complications for managers who are not able to utilise all the tools of motivation which is needed for subordinates to achieve their full potential. Recommendations were submitted that organisations should consider effectively empowering and up-skilling their managers on all the tools of motivation and techniques on how to enhance their emotional intelligence to better understand and motivate their subordinates.

- Description: In this paper we study packet delay and loss rate at the University of Fort Hare network. The focus of this paper is to evaluate the information derived from a multipoint measurement of, University of Fort Hare network which will be collected for a duration of three Months during June 2011 to August 2011 at the TSC uplink and Ethernet hubs outside and inside relative to the Internet firewall host. The specific value of this data set lies in the end to end instrumentation of all devices operating at the packet level, combined with the duration of observation. We will provide measures for the normal day−to−day operation of the University of fort hare network both at off-peak and during peak hours. We expect to show the impact of delay and loss rate at the University of Fort Hare network. The data set will include a number of areas, where service quality (delay and packet loss) is extreme, moderate, good and we will examine the causes and impacts on network users.

- Description: This paper is an investigation into the role of the Nelson Mandela Bay Metropolitan Municipality (NMBMM) in the up-keep and management of open spaces, in Zwide Township. The study examines the manner in which the legislative framework for waste management is being implemented as prescribed in legislative directives. The Constitution of the Republic of South Africa Act, 1996 (Act 108 of 1996), envisions the transformation of the local government system. Subsequently, policy frameworks and principles have been developed to support the new vision of local government. The Batho Pele Principles and the white paper were passed in March 1998. Both documents spelt out the implementation of the principle and the framework in which the local government system should operate as set out in the developmental local government concept. The developmental local government system’s core ethos lies in working with local citizenry to find ways of meeting their needs, thereby improving their quality of life. It also makes provision for public participation. Ward councillors and ward committees are an indispensable backbone of community participation. It is assumed in this study that a number of environmental, social, economic and health challenges are associated with waste disposal in open spaces. Such hazards range from health risks to the abuse of open spaces by antisocial individuals and groups. The situation is exacerbated by poor implementation of constitutional and legislative directives regarding waste management and disposal to ensure a humane and environmentally friendly atmosphere. The research assumes that the problem cannot be overcome by the NMBMM alone. Well-orchestrated community awareness education programmes such as projects like “trash is cash “and innovative ways of managing waste, including waste recycling, need to be drawn upon. The strategic placement of waste stations and the timeous collection of waste could improve the situation. The observation is that the level of service delivery varies within residential areas and in socioeconomic strata. The previously disadvantaged areas seem to have borne the brunt in terms of poor waste management services until now. The municipality has been accustomed to a situation whereby it removes the waste on an ad hoc basis in selected areas in the townships. The situation is exacerbated by little foresight into the ever growing population, specifically amongst the lower socioeconomic sector of the population. As a result, the ecology and environment is impacted in a negative way. Amidst the challenges of dumping in open spaces, a sense of determination appears within the community to want to prevent the situation; to illustrate: There is an organized group of youths who have cleaned up open spaces at along Qeqe Street in Zwide. They developed a car wash bay as a venture to generate an income. The Green Township Movement is another scheme which is mobilising the community, street by street, to keep their neighbourhood environmentally clean and green. Potentially, the Waste Management Directorate could collaborate with these groupings to halt waste dumping in open spaces. In so doing they could contribute to establishing an environmentally friendly neighbourhood. The NMBMM needs therefore to take advantage of the situation and reengineer its waste management strategy, policies and directives and augment the initiatives that the community have taken upon themselves. The study will endeavour to ultimately advise on viable strategies in an attempt to unravel barriers that have been identified, while simultaneously addressing the challenges to improving the quality of life in the township. This will be done by analysing a legislative framework and thereafter replicating the best practice used locally, nationally and internationally.. It also seeks to associate with individuals within local government in addition to groups that are like minded in combating the concern. The existing environmental regulations and the present economic situation are sound starting points. Together they present an opportunity to change the prevailing attitudes towards recycling. Finally, a number of conclusions that were arrived at during the study will be followed by recommendations. These will be based on the literature review and observations.

- Description: This study sought to do an overview and the role of Public Administration both as an academic discipline and as a discipline in practice. It sought to do a literature analysis of the macroeconomic policies and strategies that the democratic from 1994- 2012 particularly with regards to lowering unemployment and meeting public needs. The literature review on the Freedom Charter and the South African democratic government’s macroeconomic policies namely the RDP, GEAR, ASGISA, New Growth Plan, and the National Development Plan were studied in great detail in this study. Public Finance in terms of the tax revenues collected and public debt servicing costs have contributed to the capacity of the SA government to meet its public needs and social needs including poverty eradication. It identified that the NDP because of its longer term plan approach its goals could be realizable. It identified that the South African democratic government macroeconomic policy has been consistent since 1994 that of belt tightening or fiscal policy that is tight on fiscal spending and monetary policy also has remained the same although different names have been used over the period 1994-2012. The South African democratic government since 1994 has been pursuing austere fiscal policy. This is because it inherited a government that had high public debt and therefore had to prioritise of servicing that debt. That meant that there has been less funds available to spend on public needs as the aspirations of the people when they drafted and adopted in a congress of the ANC the freedom charter in 1955. The South African democratic government through its macroeconomic policy has created a number of positive changes in the country economically and socially that have benefited a lot of the previously marginalized people of South Africa however the macroeconomic objectives of reducing unemployment, growing the economy, increasing exports and lowering inflation still remain a huge challenge in this country. This study concludes that in order to increase revenues to meet public needs government needs to look at increasing its revenue base rather than borrowing the money as that will create the same challenge that it is currently facing hence it adopted the austere fiscal policy.

- Description: The textile industry in South Africa is a significant contributor to the chemical load that public wastewater treatment plants have to process, and the discharge of toxic substances, especially to the aquatic environment. In order to address this issue at factory level, the processes at a textile plant, JMV Textiles were chosen for investigation into the possibilities of minimization of discharges of harmful substances into the environment. The study followed the principles of cleaner production, and the processes that were investigated and revised were: The conventional peroxide bleaching process employed a peroxide stabilizer that did not biodegrade easily. The bleaching process was changed, so that the prevailing conditions in the fabric and dyebath facilitated bleaching without the addition of peroxide stabilizer, and also reduced the alkali and energy requirements. Polyester‐viscose fabric was pretreated by bleaching with hydrogen peroxide, which seemed to be unnecessarily rigorous, because polyester and viscose, unlike natural fibres, are relatively clean and have good whiteness in comparison with natural fibres. The proposed alternate pretreatment was a scour with detergent and alkali. The pretreatment for all polyester‐cotton fabrics was also a hydrogen peroxide bleach. Due to the ability of medium and dark shades to mask the natural tint of cotton fibres, a simpler alternate pretreatment, consisting of an alkaline scour with sequestering agent, was trialled. An unacceptable proportion of the dyeings on polyester was rejected for dye‐stains and dye‐marks. A possible solution exploited the properties of using the finishing auxiliary chemical to alleviate dye‐stains and dye‐marks during the dyeing stage, instead of using the chemical after dyeing. The highly toxic carrier that was used to facilitate level dyeing of polyester fibres that had unacceptable variation in their dyeing properties, was replaced by a less toxic carrier. The formulation for dyeing polyester was simplified to eliminate the auxiliary chemicals that were not essential to the dyeing process. Pale reactive dyed shades on cellulose and polyester‐cellulose were washed off only with hot water instead of detergent. The revised procedures consequential to the study, offered significant environmental benefits by reducing the concentration and volume of effluent produced, substituting a highly toxic carrier with a less toxic one and saving energy and water. Implementation of the suggested changes also offered financial benefits. The management of the factory, however, accepted and implemented some changes, but wanted further investigations for others and a phased approach to the other suggested changes.

- Description: On a daily basis organizations strive to achieve maximum output with minimum input for greater levels of efficiency and profitability. However, in our dynamic modern world and economy the variables have changed dramatically and the time when business was simply about the ‘bottom line’ and all else was subordinate to the objective of profit, has come and gone. In the contemporary world of business today the variables are much broader and more dynamic, as people are no longer just employees, and suppliers are no longer people whose payment should be delayed for as long as possible. In addition, the environment is no longer to be plundered at all costs. Today Lean as an all-encompassing management philosophy with its emphasis on adding value, is more relevant in business than at any other point in business history. At a time when the global economy is facing some of its greatest challenges, it is ultimately business and its networks that, through effective management, can restore the global economy and provide livelihoods to millions of people. The Lean management philosophy is about constantly searching for the best possible way of doing things and eliminating waste in pursuit of value. If Lean is in pursuit of eliminating waste and turning it into value, and the customer, irrespective of required product, is in constant pursuit of finding value, then Lean is surely the management philosophy that can deliver the greatest level of customer satisfaction. This means satisfied customers returning to an organization for repeat sales as long as they perceive that the value they derive meets their expectations.

In line with the objectives, the study established a significant number of policies and legislations that guide recruitment in the ministry and in the South Sudan Public Service. The findings of the study revealed that recruitment procedures exist in the public service of South Sudan amidst challenges. The researcher provided recommendations to the challenges in the last chapter of this thesis. However, there will be a need for further research on some of the issues that affect recruitment in the ministry as provided by the respondents of this study. These issues are discussed in chapter four. Thus recruitment is very important to research on further in the Public Service of South Sudan so as to ensure efficient and effective service delivery through recruiting competent staff.
