- Description: Using Tinto‟s (1993) interactionalist theory of student retention and Beatty Guenter‟s (1994) students retention strategy as guiding lenses, this study investigated the implementation of five student retention programmes in two universities in South Africa. Specifically the study sought to interrogate a) the mechanisms used to select students and peer facilitators who participate in each of the programmes, b) the delivery strategies that are in place and c) the programme monitoring and/or evaluation mechanisms in place to ensure that programme goals are achieved. The study adopted a concurrent mixed design embedded in the post positivist paradigm. The study revealed minimal student participation in all programmes, including those that were compulsory, owing to inconsistent enforcement of policies, stigmatisation, and poor perceptions about these programmes. In addition, the study found challenges in selection, support and monitoring of peer facilitators in almost all the programmes. This was linked to limited qualified staff, high dependence on borrowed delivery models and poor co-ordination among stakeholders. The study through a proposed Comprehensive Model for Student Retention, suggested collaborated and intensive and ongoing training of all facilitators in functional literacies, basic counselling and handling diversity, as well as co-ordinated selection and monitoring of the five programmes.

- Description: This study investigated the implementation of the Business Studies National Curriculum Statement in Schools in Fort Beaufort District. The interpretive paradigm was utilized in this study because it focuses on individual perceptions and experiences. In addition a qualitative approach was used for the collection of data so as to gain in-depth information on the implementation of the Business Studies National Curriculum. Semi- structured interviews, focus group interviews and document analysis were used as a form of collecting data. The participants were purposively selected for the sample of this study and comprised of 4 Principals, 3 Subject Advisors, 1 Provincial Subject Planner, 6 Teachers and 36 learners and interviews lasted for about 1 ½ hours. Data analysis was done in line with the research questions, aims and objectives of the study. Through the participants’ answers from schools under study, a transcript was formulated, coded and categorized in view of the implementation of Business Studies National Curriculum Statement in schools. Therefore, it was discovered from the data of the research study that the participants encounter a number of challenges with regard to teaching and implementing Business Studies in their schools. Namely: (1) lack of qualified personnel to teach Business Studies (2) lack of adequate teaching materials (3) lack of Subject Advisors executing their roles in helping teachers to teach Business Studies effectively (4) lack of training programmes and workshops on how to teach Business Studies in the classroom. Thus, there were variances in schools under study especially with relations to funding, availability of teaching material, support offered by School Heads and the Department of Education. As a result, emphasis was that the Department of Education had to come up with ways of continuously training the teachers and offering support in terms of teaching materials. Most of the participants from the school under study did not bother to plan their lessons when they were going to teach this subject. In sum, this study attempted to highlight the challenges that the participants encounter as they try to implement the Business Studies in their schools taking into the considering the educational history of their country. Hence some of the participants expressed why there is a need to create, cultivate and have a conducive and supportive working environment. The study recommends that the Department of Education provide teachers with special training on how to select relevant learning and teaching support material. Moreover, there is a greater need for Business Studies teachers to strike a balance between theory and practice in the deliverance of their lessons in Business Studies. Additionally, the District Officials must organise on-going training in Business Studies as this would help to rectify the problems that are currently being encountered in implementing Business Studies in schools.

- Description: This study explores the integration of Information and Communication Technologies (ICT) into teaching and learning within one Higher Education institution. The main question driving the study was: How is ICT integrated in the teaching and learning of mathematics, science and technology education (MSTE) in a Bachelor of Education programme? This is a case study of lecturers and students in Mathematics, Science and Technology Education. It makes use of questionnaires, interviews, field notes and document analyses to collect data. MSTE lecturers and students were assumed to be well versed in ICT usage and, therefore, well placed to assess its integration into teaching and learning. There were five main findings: First, that Mathematics, Science and Technology Education lecturers showed some ambivalence in their ontological and epistemological orientation to using ICT. Some leaned towards the instruction paradigm and used ICT as a tool for the transmission of knowledge; others leaned towards the learning paradigm, showing an awareness of the need to elicit discovery through ICT. Secondly, that lecturers’ understanding of ICT integration was oriented towards teaching and learning from technologies rather than with technologies. Thirdly, that processes of ‘pedagogical evolution’ were taking place, in terms of which there was a gradual but perceptible shift in the teaching and learning practice of both students and lecturers. Fourthly, there was no evidence to show that lecturers used ICT to promote innovative and creative teaching; in fact, students appeared to be more creative in using ICT resources, than lecturers. Fifthly, and finally, lecturers did not assign ICT-based tasks that promote conceptual understanding. They assigned tasks that asked students to extract and reproduce information from computers, without demonstrating understanding. When used in this way, ICT can, in fact, be de-skilling. From these findings, it can be concluded that ICT integration cannot be understood without exploring the ontological and epistemological orientations, as well as the theoretical orientations, at play in the teaching and learning situation. It is on the basis of these that people, that is, lecturers and students, make use of, ICTs to achieve desired goals. It is therefore recommended that, for the improvement of integration, there should be a greater emphasis on developing and sharing pedagogical expertise concerning ICT use in teaching and learning. It is recommended that a country-wide research survey should be undertaken, based on probability sampling and focussing on pedagogical issues in ICT integration in teaching and learning.

- Description: International students have become major role players in international education across the globe. Their enrollment in different universities has increased in the past few decades worldwide. Most of these students bring rich cultural diversity and skills to their various host institutions and countries. These trends signal the need to examine and understand international students within the South African context. Against this background, this study explores the factors that influence academic choices of international students, academic and social challenges they face and the role of social capital in influencing international student integration at the Universities of Fort Hare and Rhodes in South Africa. A qualitative research design was employed in this study. Thirty international students were selected (and interviewed) using purposive sampling and snowballing. The study found that some of the main factors that influence the academic choices of international students include availability of scholarships and funding, recommendations of the institution by family and friends, availability of preferred course and the reputation of the institution. Some of the main challenges faced by international students in these two institutions include language barriers, financial difficulty, expensive but improperly maintained accommodation and culture shock. These challenges impede the smooth integration of international students into their new academic and social environment. However, the students employ several strategies in attempt to address the challenges they face. These include joining a student or community social organization, community engagement and making friends. These social networks and organizations serve as a support system and connection hub for the students. The study recommends that it is pertinent for the University of Fort Hare and Rhodes University to meet the needs and expectations of its international students through regular surveys that give them room to speak about their experiences. The need for efficient International Offices at both institutions is crucial as well as the employment of open‐minded multicultural trained staff in these offices. The study also suggests the need for the both institutions to provide affordable and comfortable accommodation for its international students.

- Description: Critical illness is typically associated with a catabolic stress state in which patients commonly demonstrate a systemic inflammatory response that brings about changes in their body systems. Changes in the body systems make the critically ill dependent on mechanical ventilation and inotropic support for longer periods in order to survive. However, this inflammatory response can be attenuated by the timely introduction of nutritional support to provide energy and nutrients to diminish catabolism and promote anabolism. The result could be a decrease in the morbidity and mortality rates, as well as the financial burden on the patients, institutions and the state. Since registered nurses initiate and utilise feeding protocols to achieve target goals, there is a strong need for nurse-initiated feeding protocols. These protocols should be coupled with a comprehensive nurse-directed nutritional educational intervention that will focus on their safe and effective implementation. This focus on nursing nutrition education represents a major shift away from traditional education which has focused on dietitians and physicians. Evidence suggests that incorporating guideline recommendations into nurse-initiated protocols for starting and advancing enteral feedings is an effective strategy to improve the delivery of nutritional support. The study was aimed at exploring the provision of nutritional support to critically ill hospitalised patients by registered nurses to identify and describe possible gaps in the practice, through determining the potential relationship between the provision of nutritional support and characteristics of its providers. A quantitative, descriptive correlational study was undertaken. Seventy registered nurses working in neonatal/paediatric and adult critical care units in two public and three private hospitals in East London in the Eastern Cape participated in the study. The sample also included public critical care students. The results showed that registered nurses in private hospitals have more knowledge about the importance of nutritional support than their public hospital counterparts and students. The mean score was on the question was 80.3% with the highest score of 91% which was for the private hospital nurses, followed by 77.2% for public and 71.4% for students. Again, the mean score for knowledge on timing of initiating nutritional support was 48%, the highest score being 69.4% for students followed by private hospital nurses with 49.6%. Close to 63% (n = 44) of these nurses were either unsure about the availability of nutritional protocols or clearly attested to their non-availability. This is seen as an issue of concern because a protocol is meant to be a standard document with which all members of the ICU should be familiar. It is meant to guide and facilitate the manner of working in the unit. While facilitation of maintenance of nutritional support to patients is the responsibility of registered nurses, according to Regulation 2598(1984) section 45 (1) (q) of the South African Nursing Council, 68% (n = 48) of the respondents felt that this was in the practising scope of doctors and dietitians. The study concluded that the nurses are knowledgeable about the importance of nutritional support but knowledge gaps have been identified as far as the timing of initiating nutritional support is concerned. Some attested to unavailability of standard guidelines that are tailored into protocols guiding the provision of nutritional support by registered nurses in the critical care units. Nutrition should be prioritised as an important therapy for improving the outcomes of critically ill patients. Nurses need to analyse its provision, identify barriers to nutritional strategies and engage in nutritional education to empower themselves regarding the practice. Most importantly, there is a need for nurse-initiated nutritional protocols that are tailored from the broad nutritional guidelines and aligned with the local context and ways of practising. Nutritional support should be included as a key component of the curriculum in academic programmes that specialise in critical care nursing.

- Description: The Internet of Things (IoT) environment involves the interaction of numerous ‘things’. These ‘things’ are embedded with different kinds of technologies such as RFID technology, NFC technology and sensors. This causes IoT to bring into play many security risks apart from the ones that already exist in the current Internet, for example, embedded RFID tags can be easily triggered and send their content which could be private information. IoT also introduces internal attacks such as on-off attack, bad mouthing and white washing attacks into networks that already exist. These internal attacks cannot be solved by hard security mechanisms such as cryptographic algorithms and firewalls because they guarantee total trust. This eliminates uncertainty which should always be available where trust exist. That is, hard security mechanisms enable IoT ‘things’ to either trust another ‘thing’ completely or not and this makes them unsuitable for the IoT environment. When objects in any network are communicating, there is some element of uncertainty. Also, hard security mechanisms such as public key cryptography cause communication overheard in the already resource-constrained IoT devices and these conventional cryptography methods cannot deal with internal attacks. This brings about the need for a middleware that includes functions that will manage trust, privacy and security issues of all data exchange, communications and network connections. For IoT to be successful, the provision of trust, security and privacy measures are essential. Trust management may enhance the adoption and security measures in IoT. Trust helps in identifying trustworthy ‘things’ in the network and give ‘things’ in the network the ability to reason in all aspects concerning trust in the environment. Trust can be administered through a trust management model. This research notes that most of the trust models that have been proposed fail to address scalability challenges and lack suitable computation methods. It is on that premise that this research focuses on developing a suitable trust model for the IoT environment. The research also introduces new ways of creating relationships in IoT. This enables the creation of new cooperation opportunities in the environment. In overall, this research aimed to design and develop a generic trust and authority delegation model for the heterogonous IoT environment that is scalable and generalized to cater for the heterogeneous IoT environment. This research was conducted in three phases. The first phase reviewed literature in order to identify outstanding issues in IoT trust management and also identify the suitable computational method. This provided a critical analysis of different computational methods highlighting their advantages and limitations. In the second phase of the research, the proposed trust model was designed and tested. In the last phase, the feasibility of the proposed model was evaluated. The proposed model is based on fuzzy logic. Fuzzy logic was selected for trust computation because it is able to imitate the process of the human mind through the use of linguistic variables and it can handle uncertainty. The proposed model was tested in a simulated environment. The simulation results showed that the proposed model can identify selfish and malicious entities effectively. The results also showed that the model was able to deal with different types of behaviours of entities. The testing proved that the proposed trust model can support decision making in IoT based on trust. The results from the evaluation show that this research ameliorates the design and development of trust management solutions for the IoT environment.

- Description: Both communication, and the methods and tools of commerce have evolved over time through the invention of new technologies. The latest of these technologies are mobile devices and electronic commerce respectively. The combination of these two technologies has resulted in the creation of electronic commerce which also enables mobile payments. Mobile payments (mpayments) are enabled by many technologies with Near Field Communication (NFC) being the most recent one. NFC is a wireless technology that enables mobile devices in close proximity to exchange data. The mobile device has already been enthusiastically accepted by the customers and they carry it with them wherever they go and this makes it a good device for providing a payment method alternative. This research looks at contactless mobile payment as a payment method. Customers in marginalized rural areas lack a payment alternative to cash hence in this research we are investigating and proposing the use of a NFC enabled mobile payment application for Marginalized Rural Areas. This research extensively evaluates and assesses the potential of using NFC enabled m-payments in Marginalized Rural Areas in South Africa by carrying out an investigation of the technology and its acceptance by customers. The investigation of the technology included implementation of a prototype application which was used to introduce the technology to the consumers. The customer acceptance of the NFC enabled mobile payments was evaluated using the Technology Acceptance model (TAM). The model was modified to suit the context of this study by adding more constructs. This research concluded that Near Field Communication enabled m-payments have great potential to be used and accepted by people in the marginalized rural areas.

- Description: Cymbopogon validus and Hyparrhenia hirta belong to the Poaceae botanical family. Both plants are used as thatching material; H. hirta is also used for weaving mats and baskets. In this study, we investigated the anti-inflammatory effects of C. validus and H. hirta essential oils on fresh egg-albumin induced edema on Wistar rats. To fully understand the chemically induced anti-inflammatory properties of these plants, we first analyzed the chemical composition of the essential oils. The essential oils were analyzed using gas chromatography-mass spectrometry (GC-MS). In C. validus, 13 compounds accounted for 74.3% of fresh leaves oil, 14 compounds 71.8% of dried leaves oil and 12 compounds 73.3% of flower oil were identified from the GC-MS Chromatogram. The percentage yields were as follows fresh leaves oil 2.2%, dried leaves oil 2.0% and flower oil 2.4% v/w respectively. Linalool (3.2-29.6%) and northujane (4.4-16.9%) were the dominant compounds found in the 3 oils analyzed. While, α-terpineol 37.5% and verbenone 13.5% was only found in the fresh leaf oil, this was absent in the dried leaves oil and the flowers oil of C. validus. In H. hirta, 25 compounds accounted for 68.1% of fresh leaves oil, 40 compounds 71.9% of dried leaves oil, 23 compounds 77.6% of fresh flowers oil and 18 compounds 80.1% of dried flowers oil were identified from the GC-MS Chromatogram. The percentage yields obtained from the different parts were 3.4% for fresh leaves oil, 2.8% for dried leaves oil, 2.8% for fresh flowers oil and 0.7% for dried flowers oil v/w respectively. Northujane (8.5-30.0%), diisooctyl phthalate (4.4-26.5%), phytone (1.1-10.4%) were the dominant compounds found in the 4 oils analyzed. While, dibutyl phthalate 26.9% was only found in the fresh flowers and was absent in the dried flowers oil. Moreover, caryophyllene oxide (1.7-9.6%) was found in fresh leaves and dried flowers oil of H. hirta. In vivo analysis revealed that the two essential oils displayed significant edema inhibition effect overtime. They displayed strong anti-inflammatory properties when compared to control group. However, the H. hirta essential oil was more effective than that of C. validus. Linalool, α-terpineol, and northujane extracted from C. validus and H. hirta essential oils might have contributed to the anti-inflammatory effects observed in Wistar rats. This study, confirms the anti-inflammatory properties of C. validus and H. hirta suggesting that they may be used in diseases related to anti-inflammation.

- Description: This study investigated the relationship between job engagement and locus of control on the one hand, and organisational citizenship behaviour on the other among non-academic and academic employees of the University of Fort Hare. Job engagement and locus of control were the independent variables and organisational citizenship behaviour was the dependent variable. Data was drawn from a sample of 300 participants. A questionnaire was used to collect the data. It consisted of four sections including biographical and occupation data questionnaire. To measure job engagement, the 18-item Rich et al., (2010) job engagement scale, with a 5-point Likert scale was used. To measure locus of control, the 16-item Spector (1988) work locus of control scale was used, with 6-point Likert scale. To measure organisational citizenship behaviour, the Fox & Spector (2011) 20 item organisational citizenship behaviour questionnaire, with a 5-point Likert scale was used. Data was analysed using various statistical techniques including the Pearson Product Moment Correlation Technique and the generalised linear regression model. The results indicated that job engagement has a significant positive correlation with organisational citizenship behaviour and locus of control also has a significant positive correlation with organisational citizenship behaviour. However the results also indicated that when job engagement and locus of control are put together, they do not account for a significantly higher proportion of variance in organisational citizenship behaviour than each of them separately. Furthermore, as far as OCB-P and OCB-O are concerned, the results indicated a partial support of the research hypothesis that job engagement and locus of control together account for a significantly higher proportion of variance in organisational citizenship behaviour than any of the two separately. The study recommends that managers in organisations must focus on improving job engagement and promoting internal locus of control in order to ensure high levels of organisational citizenship behaviour.

- Description: This research study investigated the effect of job engagement to organisational stress and the employees’ intention to quit among administrative personnel at the University of Fort Hare. The main objectives of this study were determining the effects of organisational stress on employees’ intention to quit, examining the role of job engagement as a moderator of the relationship between organisational stress and employees’ intention to quit, and providing results that would lead to a deeper understanding of the nature and extent of the relationship between organisational stress and intention to quit. A survey method was adopted for this study. A questionnaire comprising of four sections: biographical information, ERI questionnaire for stress, turnover intention, and UWES scale, was administered to non-academic support personnel of the University of Fort Hare in all three campuses namely Alice, Bhisho, and East London. Simple random sampling was used to select the participants. The literature reviewed displayed a great need for managers to understand organisational stress and its causes, and how to manage and cope with stress so as to avoid losing employees, especially highly competent employees. The study yielded results that show that there are interrelationships amongst the three variables, and that job engagement does moderate the relationship between organisational stress and employees’ intention to quit.

- Description: Feedback has an important role to play in the performance of learners. This study looks to identify the challenges that the learners are faced with when the teachers provide them with feedback and the ways they would like like it to be used in order to see feedback assisting them in their learning and improve their performance. Feedback contributes a lot to assessment and has a close link with performance. The study used the qualitative approach to identify the challenges the learners experience when they receive the feedback from their teachers. The participants were sampled from grade 12 learners in the form of a focus group (seven to ten per school) and individual respondents. The method used semi-structured interviews and portfolio observations to collect the data from two high schools in East London (EL) district to look at the nature of the feedback provided to learners. The data was later analysed and interpreted. It has been identified that for both schools feedback conveyed certain messages to learners such motivation to do better, a need to do better and, lastly, affirmation that the learners are on the right track or they are neglected and left to figure out how to do the tasks. The study discovered that, according to Hattie and Timperley (2007)’ there are four levels of feedback. It was found that for the task level learners from school A mainly received oral feedback which was often seen as denigrating them; however, in school B learners received both the oral and written feedback. They felt that the feedback assisted them to understand the task at hand. They also saw this as a way of building up their confidence in all the tasks they come across. Secondly, in the process level, learners in school A did not report receiving feedback at this level but only oral feedback which does not show their mistakes step by step in the task, yet in school B they reported that they got feedback from their teacher individually to help them understand the task. Thirdly, for the self regulation level, in school A there was no data to confirm this. Regarding school B, learners were being assisted by the feedback they received from their teacher and this caused them to monitor their progress. The fourth and last level is the self or personal evaluation where in school A learners were not able to evaluate themselves because they did not receive written feedback, whereas in school B learners could do that freely referring to the written comments from their teacher. The research therefore concluded that in one of the schools the four levels that the study was looking at were not all addressed and thus no meaningful feedback was given. For school B the teacher gave them the feedback which has contributed a lot in their learning. The study recommends that feedback should not be used for right or wrong answers but it must also state clearly why the learner has obtained such mark or grade and what to do to correct the wrongs. Teachers should consider that learner errors also assist them to have a broader picture on what more they need to do in their subjects. It is also recommended that teachers should consider various strategies in giving feedback and the learners’ work has to be monitored timeously for the purpose of the learning process. Lastly, a good approach when feedback is provided is also important because it builds high self-esteem and develops the teacher-learner approach accordingly.

- Description: Information Technology (IT) has emerged as an important issue for the public and private sectors. It has been initially identified as a vehicle in supporting business processes by speeding up the process of decision making and easy access of information as required for the competitive advantage of businesses. Organisations regarded IT as an enabler of their business processes. As IT has grown, its shape and definition have drastically changed from being an enabler of the business processes to become a central and strategic concern within the organisation that drives the business processes. The new IT landscape has made organisations completely dependant on IT for their decision making and effective functioning. The dependence on IT has created a need for unified and effective structures, standards and best practices that ensure the effective execution of business processes using IT. The establishment of IT Governance for institutions of higher learning has created the dual challenges of how IT Governance can work within the culture of inclusiveness and shared decision making while better aligning existing IT structures. These dual challenges vary from one university to another based on the culture of the specific university. This study therefore suggests possible ways that IT Governance can shape an institution of higher learning by strategically aligning the institution’s IT strategy with the overall university strategy through the development of an IT Governance Model. To come up with the said proposed model, qualitative research techniques such as document analysis, observations, interviews, a questionnaire and briefing sessions were used during the research process. The comparative analysis of the case studied was used to identify different IT Governance models adopted by other universities. Literature was reviewed to establish the emerging IT Governance practices established and implemented by different authors. The result from this study is that an IT Governance model specific to WSU has been developed. This model can be used as guiding tool in establishing new IT Governance structures and also modify and improve the existing IT Governance structure of different institutions of higher learning. This model can further be used to guide the development of the institution IT Governance implementation architecture framework.

- Description: Unsustainable patterns of consumption by humankind have increased the rate of change in the natural ecosystems and consequently the levels of stress experienced within the environment. Access to sufficient good quality water is essential and a requirement to meet a number of the Millennium Development Goals (MDGs). However, poor land management and untenable agricultural practices have become the main drivers of the declining watershed services. Upstream farmers often have little or no incentives to take these impacts into account in their decision-making process. Therefore, without investment in ensuring proper land management, the trend in watersheds degradation will continue. Payment for Environmental Services (PES) has emerged as an incentive–based tool that is expected to motivate farmers to improve their agricultural practices. PES is set up to facilitate the process whereby the beneficiaries of environmental services pay compensation to providers of environmental services for conserving the ecosystem. This tool has received increasing attention as a means of creating incentive measures for managing the ecosystem, addressing livelihood issues for the rural poor, and providing sustainable financing for protected areas. The Government of Kenya, as part of its efforts to improve water resource management, is considering use of economic incentive. However, there is insufficient information to guide policy making in that direction. Little is known about the farmers’ preferences for management schemes that will affect land use patterns, their willingness to accept compensation and the willingness of potential buyers to pay for the services. This study evaluates the willingness to accept and the willingness to pay for environmental services with a view to assessing the viability of a PES scheme for the Kuywa Watershed in particular, as well as the Mt. Elgon Ecosystem and other areas with similar conditions. The objectives of the study are threefold (i) to examine respondents preferences for management options for the provision of environmental services in the watershed of River Kuywa of Mt. Elgon Ecosystem; (ii) to evaluate households’ willingness to pay (WTP) and willingness to accept (WTA) payment for improved environmental services from the River Kuywa watershed; and (iii) to propose viable PES approaches for the management of the natural resource of the Kuywa watershed and the Mt. Elgon ecosystem in general. Using six land management attributes relevant to the local situation, the study applied the conjoint method to evaluate farmers’ preferences for management options for the provision of environmental service and assess farmers’ willingness to pay and willingness to accept payment for environmental services. To enable assessment of viability, an analysis was done of the institutional and legal framework within which the PES scheme would operate. Data were collected using literature review and document analysis, questionnaires, focus group discussions and key informant interviews. Results indicate that poor water quality was the most acute problem, followed by deforestation. Results from the conjoint models show that the length of commitment period and land size that is 40% or more of the total land holding influence the farmers’ rating of the management scenarios.

The corresponding value downstream was KSh. 43/= per month over and above their regular water bill. In terms of the institutional and regulatory framework, Kenya has a wide range of policies, laws and regulation on water and other natural resources which provide an enabling environment for PES. With the decentralized institutional setup implemented in both the water sector and the agricultural sector, the institutional setting also provides an enabling environment for PES. With a positive WTA and WTP coupled with an enabling legal and institutional environment, the study concludes that PES is a viable environmental management tool for the Kuywa water shed and similar watersheds.

- Description: Unsustainable patterns of consumption by humankind have increased the rate of change in the natural ecosystems and consequently the levels of stress experienced within the environment. Access to sufficient good quality water is essential and a requirement to meet a number of the Millennium Development Goals (MDGs). However, poor land management and untenable agricultural practices have become the main drivers of the declining watershed services. Upstream farmers often have little or no incentives to take these impacts into account in their decision-making process. Therefore, without investment in ensuring proper land management, the trend in watersheds degradation will continue. Payment for Environmental Services (PES) has emerged as an incentive–based tool that is expected to motivate farmers to improve their agricultural practices. PES is set up to facilitate the process whereby the beneficiaries of environmental services pay compensation to providers of environmental services for conserving the ecosystem. This tool has received increasing attention as a means of creating incentive measures for managing the ecosystem, addressing livelihood issues for the rural poor, and providing sustainable financing for protected areas. The Government of Kenya, as part of its efforts to improve water resource management, is considering use of economic incentive. However, there is insufficient information to guide policy making in that direction. Little is known about the farmers’ preferences for management schemes that will affect land use patterns, their willingness to accept compensation and the willingness of potential buyers to pay for the services. This study evaluates the willingness to accept and the willingness to pay for environmental services with a view to assessing the viability of a PES scheme for the Kuywa Watershed in particular, as well as the Mt. Elgon Ecosystem and other areas with similar conditions. The objectives of the study are threefold (i) to examine respondents preferences for management options for the provision of environmental services in the watershed of River Kuywa of Mt. Elgon Ecosystem; (ii) to evaluate households’ willingness to pay (WTP) and willingness to accept (WTA) payment for improved environmental services from the River Kuywa watershed; and (iii) to propose viable PES approaches for the management of the natural resource of the Kuywa watershed and the Mt. Elgon ecosystem in general. Using six land management attributes relevant to the local situation, the study applied the conjoint method to evaluate farmers’ preferences for management options for the provision of environmental service and assess farmers’ willingness to pay and willingness to accept payment for environmental services. To enable assessment of viability, an analysis was done of the institutional and legal framework within which the PES scheme would operate. Data were collected using literature review and document analysis, questionnaires, focus group discussions and key informant interviews. Results indicate that poor water quality was the most acute problem, followed by deforestation. Results from the conjoint models show that the length of commitment period and land size that is 40% or more of the total land holding influence the farmers’ rating of the management scenarios. The study found that a management contract that requires use of 20% of land holding for a period of 5 years, combined with a cash incentive, harvesting partially permitted, administered by a local NGO and requiring contribution of free labour for two days had the highest likelihood of being selected. The conjoint valuation exercise also came up with a WTA by farmers upstream of KSh. 7,080/= per year. The corresponding value downstream was KSh. 43/= per month over and above their regular water bill.

- Description: Despite a progressive constitution lauded as one of the best and most forward-looking in the world, with an advanced Bill of Rights, instances of human rights violations have been detected at all levels of the South African society. The most disturbing revelations have been associated with situations in many farming communities in South Africa. On the basis of a comprehensive nationwide study initiated in June 2001 and documented in 2003, the South African Human Rights Commission (SAHRC) confirmed widespread human rights violations on South African farms. Through the efforts of the South African Human Rights Commission, many of these violations have been brought to the attention of the authorities and there are already numerous actions being taken to contain and possibly eliminate them. Among these is the Child Labour Programme of Action which was adopted in 2003 by the large number of government departments that constitute the stakeholders, particularly those that have responsibility for labour, education, provincial and local government, water services, justice, policing, prosecution, and social development. However, the SAHRC study had limited coverage due to constraints of time and funding and did not pay adequate attention to the former independent homelands. In addition to this significant shortcoming, recent international experience reveals other forms of violations that may not be immediately obvious and therefore go undetected for a very long time. Among these, the International Labour Organization (ILO), together with various non-Governmental Organizations (NGOs) and other bodies have drawn attention to existence of what are termed “worst forms of child labour”. The latter involves a wide range of abuses to which under-age individuals are subjected against their will and often exposed to hazards that may leave them permanently excluded from formal educational and economic opportunities. The fact that national definitions differ complicates the situation. As a result, systematic investigation is needed to see to what extent local practices compare with international norms and standards. Similarly, the fact that the former independent homelands were not adequately covered in such an important study that aimed to inform policy on the optimal direction of the transformation process also raises serious questions that must be addressed. This mini-dissertation documents evidence based on a rapid appraisal of farm and non-farm environments in two polar regions of the province, namely the Port St John’s Municipality in the Oliver Tambo District Municipality of the former Transkei homeland and Alice in the Nkonkobe Municipality of the former Ciskei homeland. Descriptive and content analysis methodologies were employed to analyze the data obtained from interviews of employers of labour, the labourers themselves, as well as community members and “bystanders” who had opinions about the insertion of children into the labour market. Correlational analysis and logistic regression were performed to draw inferences about the determinants of child labour in the farming system. The indication is that child labour is an established phenomenon whose discussion is however quite sensitive and elicits a wide range of emotions. The role of socioeconomic factors in influencing the decision to engage child labour seems to be quite extensive. For instance, monthly income of household has important practical implications for national and global policy on the use of child labour are foreseen and form the basis for the recommendations put forward to address the associated concerns.

- Description: Mycobacterium tuberculosis complex (MTBC) is a causative agent of tuberculosis (TB) in humans and animals. The burden of tuberculosis in South Africa is worsened by the concurrent epidemic of HIV. The dynamic of TB epidemics has been investigated and yet little data has been given about the Eastern Cape, particularly Port Elizabeth. The study aimed to investigate the prevalence of drug resistant MTBC and to determine the mutations causing resistance in Port Elizabeth. One hundred and ninety (190) DNA samples isolated from sputum specimen in humans suspected of having TB were amplified using the Seeplex® MTB Nested ACE detection assay. To differentiate Mycobacterium tuberculosis complex (MTBC) members for surveillance purposes a multiplex polymerase chain reaction (PCR) method was done based on genomic regions of differences such as RD1, RD1mic, RD2seal, RD4, RD9 and RD12. Target genes known to confer resistance to first and second-line drugs were amplified and the amplicons sequenced using Big Dye Terminator DNA sequencing kit v3.1 (Applied Biosystems, UK). The patient’s demographic profiles were obtained from the National Health Laboratory Service (NHLS). All hundred and ninety DNA samples tested positive for MTBC using the Seeplex® MTB Nested ACE assay. Results show a high prevalence of extensive drug resistant TB in Port Elizabeth, Eastern Cape Province. One hundred and eighty four (184) DNA isolates were used in the identification of different MTBC species. We ended up working with 184 DNA isolates because we ran out of DNA, and we could not go back to isolate DNA from the affected individuals due to the fact that some patients died, while some have been released to go to their homes. From the 184 DNA isolates 45 (24.5%) isolates were identified to be M. tuberculosis, 94 isolates (51.1%) to be M. bovis BCG and 3 isolates (1.6%) to be M. cannetti. Sequencing results show the position of mutation in each DNA isolate; however in the study we got resistance to MDR to be 100% and 42% pre-XDR while 58% was XDR. These results raise an alarm for the prevalence MDR in MTBC from Port Elizabeth. This is a serious health concern which calls for a need to strategise on the identification of extensive drug resistant TB patients from multi-drug resistant TB patients and ensure monitoring of their treatment.

- Description: This research study explored the inadequacies of the National Development Plan on addressing the problem of youth unemployment in Eastern Cape in South Africa. The study intended to achieve the following objectives: (i) to evaluate the employment needs of youth in relation to the identified measures of employment creation outlined in the NDP. ii) to identify the gaps in the NDP policy interventions in relation to the prospects and problems embedded in addressing the problem of youth unemployment. The literature reviewed in the study was drawn from several researchers and the study was underpinned by the human capital theory, the capability approach and the public and the private sector partnership theory. Though many theories were used, the human capital theory was the major theory adopted in this study. Since the study was qualitative in nature, an interview guide which consisted of open ended questions was used on face to face interviews and focus groups to collect data from twenty one youth and five youth representatives in the Eastern Cape. The data of this study was thematically analysed. The analysis of the study made the following conclusions about the NDP and youth employment in the Eastern Cape. Firstly, there is a problem of high youth unemployment which is above 50% in the Eastern Cape. Secondly, the NDP’s economic measures have a potential of excluding the youth and as a result, the NDP will inadequately address the employment needs of the youth. Thirdly, the youth appreciated that the NDP is realising the problem of youth unemployment but they are not happy with the NDP’s proposed employment measures of wage subsidies, low wages, labour deregulation and SMMEs because they do not solve the root causes of youth unemployment. Rather, they provide unsustainable and low quality jobs in the long run if not properly monitored. In response to the findings, the study therefore made the following recommendations: The NDP’s economic growth policy to be labour intensive compliant, human capital to match the work place skills requirements, promoting entrepreneurship skills, addressing the root causes rather than focusing on symptoms of unemployment , rethinking on SMMEs, development policies to match the local employment needs, succinct youth employment policy implementation, productivity to match the wages, complementing the private and the public sector in creating youth employment, the NDP to promote adequate link of education to self-employment from the primary level, the NDP to promote higher levels of investment for the employment benefits of the youth and the NDP to fight corruption on the misuse of youth employment grants. The study concluded that NDP’s proposed economic measures will inadequately address the youth employment needs hence there is need for relooking at the NDP to be sustainable employment responsive in nature so as to reduce poverty and inequality.

- Description: A swarm of granitic pegmatites occurs in Mzimba district from northern Kasungu to Kafukure near the western international border with Zambia. The granitic pegmatites are hosted by a mobile belt, within the Mozambiquan orogenic belt (c. 900 - 1800 Ma). They have been dated as 485 Ma. They intruded metasediments of high to medium grade metamorphic rocks of a Precambrian Basement Complex. The dominant trend of the pegmatites is NW - SE, exhibiting a cross-cutting relationship with the country rocks and their contacts with the latter are usually sharp. The six pegmatites investigated in this study are inhomogeneous, composed of a massive quartz core, an intermediate zone composed of a blocky pink K-feldspar rich sub-zone and muscovite rich sub-zone and a wall zone composed of quartz - pink K-feldspar - muscovite mineral assemblage. The Mzimba pegmatites are classified as lithium-caesium-tantalum (LCT) family of rare element granitic pegmatites as described by Černý and Ercit (2005). They belong to the beryl-columbite subtype and beryl-columbite-phosphate subtype of the rare element pegmatites. It is suggested that the pegmatites are the product of magmatic differentiation and that they form roofs of granite plutons lying deep below the current level of erosion. The six pegmatites were sampled and minerals analysed using standard analytical methods such as petrographic microscopy, X-ray diffraction (XRD) and X-ray fluorescence (XRF) analysis. Mineralogy of the granitic pegmatites indicates that they are predominantly composed of perthitic K-feldspar (perthite), Na-plagioclase (albite), quartz and muscovite as main mineral phases and accessory minerals including beryl, tantalite-columbite (ferrotantalite), iron-titanium oxides (ilmeno-rutile and ilmenite), tourmaline (schorl), garnet (almandine-spessartine) and triplite. Triplite is a very rare mineral found in a few pegmatites around the world, and this is the first reported account of this mineral in the Mzimba pegmatites and probably in Malawi. These minerals are being exploited by artisanal and small scale miners. Trace elements in K-feldspar and muscovite are significant indicators for the evaluation of economic potential of pegmatites as well as for the differentiation degree and origin of the magma. The K/Rb ratio for K-feldspars ranges between 12.72 and 109.38, while for muscovites it is between 16.66 and 82.36 indicating that the pegmatites are moderately evolved. The Ta versus Cs and the Ta versus K/Cs discrimination diagram indicates that all the investigated pegmatites plot above the 20 ppm threshold suggesting that the pegmatites have potential for Ta and Nb mineralization.

- Description: Despite according high priority to regional economic integration and being clustered by regional economic schemes, Africa’s regional economic integration record is not inspiring. With the transformation of the OAU to the African Union (AU), the New Partnership for Africa`s Development (NEPAD) was adopted as the development program of the continent to drive the impetus of economic integration through trade. At the time NEPAD was adopted, regional integration schemes in Africa were facing problems of low intra-regional trade levels despite trade being identified as the engine of activity and economic growth for regional economic integration. The study was centered on Southern Africa with precise attention on SADC. Even though trade is accepted as a vital engine of economic growth and development, this is not the case with SADC. The study was looking at the contribution of NEPAD in intra-regional trade in Africa with special focus on SADC. This was prompted by the fact that regional integration is business as usual within the sub region while problems that have been confronting regional schemes are continuing unabated after the adoption of NEPAD. The study used the historical approach because it provides the study with an advantage of accessing existing literature with regards to what is really stalling intra-regional trade in SADC. The study findings noted that NEPAD has not fully addressed the problems of intra-regional trade within SADC and the continent at large. The study lastly concludes by giving a way forward for NEPAD to respond to the specific needs of SADC for the promotion of intra-regional and equitable trade.

- Description: The main objective of this study was to explore non-governmental organisations (NGOs) and poverty reduction strategies in Zimbabwe through an assessment of the activities of the Catholic Development Commission (CADEC) in the Binga district in the Matabeleland North province. The research method used was triangulation and the theoretical framework combined insights of both the Basic Needs Approach and the Capability Theory. The core argument which has emerged is that despite criticisms levelled against NGOs that they cater for immediate relief and basic needs, the operation of CADEC in Binga shows in contrast that NGOs can operate in such a way that the capabilities of the participants can be enhanced or expanded such that the Binga district can be capable of independently engaging in sustainable livelihoods and development. This study argued that participation in projects has enabled CADEC to realise and expand people’s capabilities and participation was identified as a means of gaining a sustainable livelihood. To achieve the objectives of the study the researcher collected data using a survey questionnaire and in-depth interviews. The study was framed within the concept of Fundamental Human Needs by Manfred Max-Neef and the Capabilities Approach of Amartya Sen. The concept of Fundamental Human Needs argues that human needs do not change but the ways of satisfying the needs do change and unsatisfied needs results in poverty. The Capabilities approach on the other hand, sees poverty as caused by the deprivation of human capabilities. These theories were utilized for this study because they complement each other. Max-Neef believed that development should focus on promoting community agency where beneficiaries are the primary actors for development. Development for him is people-centred, participatory and environmentally sound whilst the Capability Approach of Sen is of the view that development is about developing or expanding human potentials. Being anchored on these two theories this study found out that CADEC use supplementary feeding, sustainable projects such as gardens and livestock production, educational initiatives, the provision of shelter and participatory development as strategies to alleviate poverty in the Binga district. CADEC’s long term projects that focus on farming practices and sustainable livelihoods have enabled Binga people to respond to their poverty. Thus, the results of this study substantiated the views on Max-Neef and Sen since CADEC does not only provide for basic needs but also enhances the capabilities of the people in Binga. However, even if the majority of the respondents believed that CADEC has managed to reduce poverty in Binga, a lot still needs to be done since poverty is still the main problem in the district.

- Description: The main objective of this study was to explore non-governmental organisations (NGOs) and poverty reduction strategies in Zimbabwe through an assessment of the activities of the Catholic Development Commission (CADEC) in the Binga district in the Matabeleland North province. The research method used was triangulation and the theoretical framework combined insights of both the Basic Needs Approach and the Capability Theory. The core argument which has emerged is that despite criticisms levelled against NGOs that they cater for immediate relief and basic needs, the operation of CADEC in Binga shows in contrast that NGOs can operate in such a way that the capabilities of the participants can be enhanced or expanded such that the Binga district can be capable of independently engaging in sustainable livelihoods and development. This study argued that participation in projects has enabled CADEC to realise and expand people’s capabilities and participation was identified as a means of gaining a sustainable livelihood. To achieve the objectives of the study the researcher collected data using a survey questionnaire and in-depth interviews. The study was framed within the concept of Fundamental Human Needs by Manfred Max-Neef and the Capabilities Approach of Amartya Sen.
