- Description: project. It did this by reviewing relevant literature in development communication. The review done showed that literature is replete with arguments critical of the dominant paradigm due to its top-down nature of communication. Scholars critical of dominant paradigm argue that participatory communication should be given a prominent role to ensure that stakeholders work in concert to realise the stated objectives of their development project. The study highlighted many contentious issues surrounding the nature and practices of participatory communication. It pointed out that the issues have played themselves out in literature in the form of different typologies of participatory practices, which were dealt with extensively in this study. The discussion of participatory communication in literature is also mindful of different models of communication and the space they occupy in participatory communication practices. In this study, there was a discussion of transactional communication models as depicted by Nair and White (1993:52) and Steinberg (1997:19). Both scholars emphasise that participatory communication will not achieve its stated purpose without mutual agreement of the parties in communication. They equally stress the recognition of the possible effects of some contextual factors which may have bearing on the prevailing nature of communication. A review of different communication tools used by participatory development communicator was given in the study. These different communication tools were discussed in view of how these tools can be used to advance participatory practice in a development project, especially with reference to the project examined in this study. Using qualitative research method, different and appropriate interview methods such as semi-structured, focus group and post-survey interviews were used to collect data from the respondents in this study. The analysis and discussion of the data revealed that different challenges on the ground could affect participatory communication practices in a development project. With regard to the project examined in this study, the analysis showed that there is a weak stakeholder relationship, especially stakeholders identified in this study as field officers. The study highlighted that stakeholders such as the agricultural extension officers and animal health technicians are not very active in the implementation process of the project. Some of the reasons pointed out is the fact that the secondary stakeholder such as the Provincial Department of Agricultural (PDoA) to which these field officers belong is not playing active role in ensuring that they complement the efforts of other field officers such as the IDC representatives. The second reason is the fact that the participatory focus of the project was not properly communicated to the beneficiaries. This also transpired in their inability to reflect participatory practice in their relationship with the beneficiaries and other stakeholders of the project. Other challenges, among others, as pointed out in the analysis showed that participatory communication practice requires expert personnel to be successful. In the case of the project examined, apart from the fact that there is shortage of manpower to handle the challenges mentioned in the study, there is no communication expert among the few active personnel in the field. The findings of this study showed that there was no clear role and identification of responsibilities let alone coordination of all actors involved in the project. Through the selected case study, this study has not only provided avenue to explore both theoretically and practically participatory communication, but has added to participatory communication discourse that there is no easy answer to challenges field officers encounter in practice. This is the reason the different participatory practices characterising nature of the project this study has investigated was given.

- Description: This thesis explores human-wildlife interactions under community managed game parks. The thesis consists of an introductory chapter, study location chapter and four self-contained studies based on different samples from created clusters surrounding Nyatana Game Park, which make up the rest of the thesis chapters. Chapter one presents an introductory overview of wildlife management in Zimbabwe, specifically looking at human-wildlife interactions under CAMPFIRE projects, welfare dynamics and conservation implications for the surrounding communities who share boundaries with community-managed game parks. The chapter concludes by highlighting the challenges facing community-based wildlife conservation in Zimbabwe as well as the key concepts that will be the subject of the rest of the thesis. Chapter two presents the study location; it highlights the road map to the study area, starting with the provincial location, and indicates the specific districts from which respondents were selected. A brief agro-ecological summary of the study area is also presented; it looks specifically at climate, vegetation and a demographic data of the study area. Chapter three: Can game parks be trusted as livelihood sources? To answer this topical question, Chapter three explores livelihood adaptation strategies for households who share boundaries with Nyatana Game Park. Most of the community managed game parks, under CAMPFIRE principles in Zimbabwe, were established with the primary objective of generating revenue for the surrounding communities; this was done in the hope of using positive returns from game farming to promote the conservation of wildlife. Has this materialised in practice? Descriptive results from this study seem to suggest otherwise, where mixed farming and gold panning were the major livelihood adaptation choices reported by most households. The revenue from game farming was reported to be too low and inconsistent, to such an extent that the majority of the community regarded it as risky and unreliable. A multinomial logistic regression model for correlates of adaptation choices indicated that access to credit, markets, and extension may be some of the current institutional constraints inhibiting households from accessing off-farm sources for their livelihoods. In addition, household size, gender and age may enhance the adaptive capacity of households to move out of risky crop faming into other off-farm portfolio diversifications. The study, therefore, suggests that game parks, according to the evidence uncovered by the study, may not be trusted as a reliable and sustainable livelihood source. If local communities who share boundaries with game parks do not view them as reliable and sustainable livelihood sources, as concluded in Chapter three, how can they (local communities) be trusted to conserve them? To assess their perceptions of game parks, Chapter four presents a multinomial logistic regression model for perceptions of society on game parks using the African elephant as a typical example. The results suggest that Problem Animal Control (PAC) perceptions, livestock predation and issues of low and poor revenue distribution may be some of the critical perceptions capable of influencing surrounding communities to negatively participate in the conservation of wildlife. The results further suggest that using wildlife proceeds to finance observable local common pool infrastructure may positively influence the surrounding communities to conserve wildlife. The chief conclusion regarding game parks, therefore, was that the surrounding communities were in favour of the obliteration pathway, although minimal conservation perceptions were also available. Given the negative conclusions regarding game parks, as suggested in Chapters three and four, citizens would then wonder if any meaningful hope for community managed game parks exists. Chapter five probes the buffer zone livelihood link under community managed game parks, using evidence from the Nyatana Game Park. The binary logistic regression model results, for buffer zone participation and resource extraction combinations by surrounding communities, suggest that resource extraction may be market driven rather than focussing on domestic consumption. The study therefore concludes that the buffer zone livelihood link as currently practiced, though potential, may fail to address the livelihood expectations of the sub-district producer communities. The study therefore calls for extreme caution whenever the buffer zone livelihood link is considered, because several institutional and design conflicts exist within this dynamic. In Chapter six, the study further probed the buffer zone income dynamics for the sub-district producer community. The results of descriptive statistics suggest that the contribution of buffer zone activities to household income may be significant with a positive correlation to household agricultural income for communities who reside inside or close to the park (primary sub-district producer community). Using the Gini decomposition approach and Lorenz curves, the study concluded that a buffer zone income may be capable of contributing to more equally distributed incomes for rural communities who share boundaries with game parks. With respect to the correlates of household income, the results suggest that household size and age may negatively influence income from buffer zone activities, while gender may have a positive effect. This was also true for education and Livestock Units (LUs) with respect to income from self employment; the former positively and the latter negatively related. The results further suggest that land size may also be positively significant in order to explain income from agriculture as well as total income. With regard to the distance from the buffer zone, the results suggest a negative influence with respect to the buffer zone, agriculture and total income. The implied message therefore suggests that buffer zones may provide active livelihood sources which are capable of financing rural household agriculture. The income equalizing effect which is portrayed may also further imply that, if correctly targeted and promoted, a buffer zone income could possibly address the current income inequality which is generic in rural areas. However, this potential may not be realized due to the current buffer zone design status (created for local secondary use as opposed to commercial primary use), restrictive policies and poor institutional support. With this dilemma facing community managed game parks (threats as summarised in Chapters three and four amid the potential hope summarized in Chapters five and six), Chapter 7 concludes the study by suggesting that the human-wildlife interaction model, though currently theoretical, may have significant practical potential in addressing the livelihoods of the surrounding communities as well as promoting the conservation of wildlife. This could be possible if available challenges that range from low revenue, insecure property rights, high human-elephant conflict and institutional design conflict for buffer zone utilization are corrected by means of the free market system. This would allow market forces to deliver on the expectations of the ―human-wildlife interactions model‖ – sustainable livelihoods for the former and intergenerational conservation for the latter.

- Description: This study assessed the implementation of Continuing Professional Development (CPD) Programmes for primary school teachers in Zomba Rural Education District in Malawi. The study arose from a concern that, despite the Government of Malawi putting in place structures to facilitate the implementation of CPD for primary school teachers, research has shown that teachers have not improved their classroom practice. As a result, there has been poor learner performance at all levels of the primary education system to the extent that learners scored the lowest in the 2005 international examinations for the Southern Africa Development Community. From the literature, it appears that no thorough and conclusive studies to look into the issues behind the implementation of CPD programmes in Malawi have been conducted. Hence the researcher was motivated to assess how the CPD programmes are implemented with the view to explore better ways of implementing CPD programmes for teachers that can result in teacher change. The study was placed within the post-positivism paradigm and used a mixed method research design that incorporated concurrent procedures in the collection, analysis and interpretation of the data. Questionnaires were used to collect quantitative data while qualitative data were collected through interviews, focus group discussions, CPD observations and document analysis. A total of 798 teachers filled the questionnaires. This figure represented 47% of the total number of teachers in the district. The researcher conducted 34 focus group discussions with teachers from various schools. She also held interviews with 34 head teachers and CPD programme facilitators (12 Primary Education Advisors and 3 CPD facilitators from organizations). Other interviews were held with the District Education Manager, the Coordinating Primary Education Advisor, the Coordinator of the New Curriculum, and the Coordinator for the Department of Teacher Education and Development. Further, the researcher made 3 CPD observations. The study revealed weaknesses in the implementation of CPD programmes for teachers in the district. Generally the study noted that there was much emphasis on the transmissive model of CPD implementation, to the neglect of transitional and transformative models such that the personal, social and occupational aspects of professional learning were not holistically considered in the programme designs. Specifically, the duration of the programmes was found to be inadequate for meaningful assimilation of new knowledge and skills; the expertise of facilitators was sometimes questionable; and the use of the cascade mode left teachers unsure and with knowledge gaps. Further, the study noted that the monitoring and support mechanisms for the programmes were weak; the consultation processes for teacher inputs in the CPD programme designs were dismal; and the welfare of teachers at the CPD venues was poorly handled.. At school level the study revealed that the teaching and learning environment compounded the problem of teachers’ difficulty in implementing what they learnt from CPD training. Large classes, inadequate teachers, lack of teaching and learning resources, limited infrastructure, lack of accommodation for teachers, lack of support from colleagues and learner absenteeism were some of the factors hindering implementation of CPD programmes at school level. The study has put forth recommendations for the effective implementation of CPD programmes for teachers in the district. Furthermore, based on the findings of the study and an extensive literature search, the researcher has suggested an alternative model for CPD implementation that can result in teacher change. Overall there is need for collaborative effort among stakeholders in education to ensure effective delivery of CPDs and their subsequent translation into practice at classroom level.

- Description: The main purpose of this study was to evaluate the impact of co-operative societies on poverty alleviation among the urban poor in Zimbabwe with particular reference to consumer co-operative societies in areas of agriculture, housing and micro- finance. The co-operative sector plays an important role in poverty alleviation since many unemployed people have turned to co-operative activities as a way of earning a lawful and decent living during a period in which Zimbabwe generally suffered immense impoverishment in the midst of the national economic meltdown that was characterised by hyper-inflation, de-industrialisation and mass unemployment. The period of study was as from January 2008 to August 2010. This period is significant in that many co-operative societies were formed with the following broad objectives: (a) economic power and through this power; (b) control of socio-economic institution, to eliminate exploitation of man by man to make the people of Zimbabwe self reliant; (c) skills management, goods and services and establish in themselves a sense of confidence, initiative and high development aspirations; (d) to provide an opportunity to develop the community; and a (e) collective way of living that provides a sound base for socialism and national solidarity ix In this study, two hundred and seventy four respondents were used as research subjects. This consisted of one hundred and sixty respondents from housing, twenty four from micro- finance, and eighty eight from agricultural co-operative societies which covered dairy, poultry and fishing co-operative societies. This also included the Registrar of Co-operatives and the Harare City Council Co-operative officer. The research instruments that were used for the purpose of this research study were questionnaires, field visits, interviews and observations. Use was also made of secondary data that was obtained from the offices of Registrar of Co-operatives and the Town clerk of the Harare City Council as well as from the various co-operative societies that constitute the research study’s sample. The key factors that account for the failure of co-operative societies included the lack of adequate funding, lack of relevant knowledge and experience about co-operative activities, conflict among co-operative society members, failure to follow co-operative principles, mixing politics with co-operative activities and lack of education and training. The study also found out that the key to the success of any co-operative venture includes some of the following factors: Proper application of co-operative principles, the provision of co-operative education to both the membership and management of co-operative societies and proper keeping of institutional records. Most important of which include membership, financial and asset registers. x The study recommends that the government should give adequate administrative and financial support to co-operative societies since they have a potential of alleviating poverty if properly managed. It is also further recommended that research be done in order to enhance the strategic management of co-operative societies since empirical evidence tends to suggest that they are a viable tool for broad –based participatory and democratic sustainable livelihoods development. The study also recommended further studies to be carried out on the applicability of cooperative principles in all environments since some co-operative societies that have followed these principles especially in the developed countries have proved to be suitable instruments for poverty alleviation.

- Description: Education has been identified as a priority area by the South African government, in particular by the African National Congress as the ruling party. To this end, huge amounts of money are being spent on education as a service that has been approved by the legislators. Rules and regulations have been promulgated, and among others, the South African Schools Act, Act No. 84 of 1996, has been enacted. Rich research has also been funded with the sole intention of providing quality education to the people. Education of unacceptably poor quality has, however, been the result, as postulated by Peterson and Hassel (1998:55). The above are attested to by the findings that the political tensions emanating from the conduct of the South African Democratic Teachers’ Union and the Professional Educators’ Union, leading to class disruptions and general instability, erode the ethos of accountability on the part of educators and therefore impact negatively on service delivery. Furthermore, the Limpopo Department of Education is not immune to the challenges ranging from the elements of corrupt activities that often surface, teacher attrition which in the main is caused by lack of discipline. Winkler, Modise and Dawber (1998) indicate that teaching has never been easy, and many teachers are leaving their jobs because of the many problems with children in classrooms. Some of the problems cited are children who do not want to learn and learning that is becoming too difficult for the students because they do not want to listen. This study adopted sequential mixed methods namely, quantitative and qualitative research methods which are viewed as complementary rather than opposing approaches. Information was amassed from the subjects through interviews, observation, documentary survey and observation and the information has since been triangulated to validate the facts. All the methodologies employed proved to be useful in this study. The study sought to test the hypothesis “Good governance is informed by strong accountability and future-oriented organisation, continuously steering it towards its mission and vision, and thereby ensuring that the day-to-day management and administration are always linked with the organisation’s values and goals and thus eventually bringing about effectual and accelerated service delivery” to the South African populace without compromise. After empirically testing the hypothesis, showing mixed reaction informed by the findings of the study, five recommendations were made, based on the conclusions arrived at.

- Description: The broad objective of the study was to determine the economic value of local pigs in marketand subsistence-oriented production systems in communal areas of Southern Africa. Data were collected from 288 households to investigate farmer perceptions, effects on pig production and handling of disease outbreaks such as classical swine fever (CSF) in market- and subsistenceoriented production systems. The utilisation of local pigs in these market- and subsistenceoriented production systems in improving people‟s welfare was evaluated. Climate change was identified by farmers in these production systems as a major constraint to pig production hence an experiment was carried out in the hottest season to determine diurnal heat-related physiological and behavioural responses in Large White (LW) and South African local pigs. The same genotypes were used to determine effects of diurnal heat-related stress on their growth performance. Choice experiment was done to determine farmer preferences for local pig traits and implicit prices for these traits in CSF-affected and unaffected areas that were under subsistence- and market-oriented production systems. In this experiment, the importance of heat tolerance was assessed relative to other productive and climate change adaptation traits. Significantly more pigs were culled in the CSF-affected areas that were market-oriented (8.0 ± 1.76) than subsistence-oriented (4.1 ± 1.00) production system. The risk of parasites and disease challenges was high in subsistence-oriented production system and coastal areas. In both production systems, CSF was perceived as destructive since the culling of pigs affected pork availability and income generation. The high risk of disease outbreaks and threat of climate change caused farmers in subsistence-oriented production system to select local pigs for their adaptive traits while those in the market-oriented production system focused on productive imported pigs. Farmers (83 %) indicated that they wanted pig genotypes that were adapted to climate change effects such as hot conditions. Local pigs were found to have superior heat tolerance over LW pigs (P < 0.05) in terms of lower heart rate and skin surface temperature. Frequency per day and duration for behavioural heat loss activities such as wallowing, sleeping in a prostrate posture and sprawling in slurry were also lower (P < 0.05) for local than LW pigs. The superiority of heat tolerance of local over LW pigs was further confirmed by their uncompromised growth performance under high diurnal temperatures. The Pearson‟s product moment correlation coefficient between temperature and feed conversion ratio for LW pigs was strongly positive (r = 0.50; P < 0.001) unlike the weak and positive correlation for local pigs (r = 0.20; P < 0.05). There was a quadratic relationship between temperature and average daily gain (ADG) for both pig genotypes. The regression coefficients for ADG were higher (P < 0.001) for LW than local pigs. It was concluded that at high ambient temperatures, performance of local pigs was less compromised than for LW pigs. Although local pigs were found to be heat tolerant, results of choice experiment showed that this trait was not selected for relative to other traits. Keeping pigs that required bought-in feeds, fell sick often and produced low pork quality (eating quality based on farmer perceptions) negatively affected farmers‟ livelihoods more in subsistence- than market-oriented production system. Farmers in market-oriented production system derived more benefit from productive traits such as heavier slaughter weights and large litter size than subsistence-oriented farmers. Under the subsistence-oriented production system, farmers in CSF-affected areas placed high prices on adaptive traits than the unaffected areas. Subsistence-oriented farmers who were affected by CSF wanted a total compensation price of R10 944.00 (USD1563.43) for keeping a pig genotype with unfavourable traits when compared to R4235.00 (USD605.00) for their CSF-unaffected counterparts. Implicit prices for traits could not be determined for market-oriented production system. It was concluded that farmers in CSFaffected areas placed high economic values on pig traits than farmers from the CSF-unaffected areas. The findings suggest that adapted local pigs can be promoted in subsistence-oriented production systems while productive imported pigs and their crosses with local pigs can be kept in market-oriented production systems.

- Description: Different forms of racial segregation have been practiced in different countries the world over. However, the nature of South Africa‟s apartheid system, as it was practiced from 1948 until the dawn of the democratic dispensation in 1994, has been a subject of debate in South Africa and even beyond. Apartheid was a policy that was designed by the then ruling Nationalist Party for purposes of dividing and stratifying South Africa along racial lines - whites, blacks, coloureds and Asians. It thus promoted racial segregation and/or unequal stratification of society. In South Africa‟s hierarchy of apartheid, blacks, who constituted the majority of the population, were ironically the most destitute and segregated. Some historians believe that South Africa‟s racial policy was designed against the backdrop of Jim Crow, a similar system of racial discrimination which was instituted in the American South late in the 1890s through the 20th century. Jim Crow and apartheid are, in this study, considered as sides of the same coin; hence for the sake of convenience, the word apartheid is used to subsume Jim Crow. Although South Africa‟s apartheid system was influenced by different ideologies, for example German missiology as applied by the Dutch Reformed Church, historian Hermann Giliomee (2003: 373) insists that „the segregationist practice of the American South was particularly influential.‟ Given the ideological relationship between apartheid and Jim Crow, the present study investigates the interplay of compatibility between apartheid/Jim Crow and crime and violence as reflected in selected works of Richard Wright (African American novelist) and Athol Fugard (South African playwright). The aim of the study is firstly, to examine the works in order to analyse them as responses to apartheid and by extension colonial domination and secondly to investigate crime and violence. The three criminological theories selected for this study are strain theory (by Robert Merton), subculture theory (Edwin Sutherland) and labelling theory (Howard Becker). While criminological theory provides an empirical dimension to the study, postcolonial theory situates the study within a specified space, which is the postcolonial context. The postcolonial is, however understood, not as a demarcated historical space, but as a continuum, from the dawn of colonization to the unforeseeable future. Three postcolonial theorists have been identified for the purposes of this study. These are: Frantz Fanon, Homi Bhabha and Bill Ashcroft. Fanon‟s psychoanalysis of the colonized, Homi Bhabha‟s Third Space and hybridity as well as Ashcroft‟s postcolonial transformation are key concepts in understanding the different ways in which the colonized deal with the consequences of colonization. It has been suggested particularly in Edward Said‟s Orientalism (1978) that the discourse of orientalism creates the Oriental, as if Orientals were a passive object of the colonial adventure. This study uses Bhabha‟s and Ashcroft‟s theory of colonial discourse to argue that the colonized are not only objects of the colonial enterprise but also active participants in the process of opening survival spaces for self-realization. The various criminal activities that the colonized engage in (as represented in the selected works of Richard Wright and Athol Fugard) are in this study viewed as ways of inscribing their subjectivity within an exclusive colonial system.

- Description: This study used integration as the overarching conceptual framework to investigate socio-spatial integration in post-apartheid South Africa. The study adopted the embedded case study design to investigate the spatial and social aspects of integration in former white residential suburbs in East London, South Africa. Recognising that integration occurred in different registers, this study used data from the South African Property Transfer Guide (SAPTG) database to investigate spatial-temporal integration in East London‟s residential suburbs from 1993 to 2008. A total of 21,683 residential property transfers were reviewed in 46 suburbs, and transfers to Blacks were identified. The residential property transfers were mapped to identify the nature of spatial integration. To investigate social integration, in-depth personal interviews were conducted on a purposively drawn sample of residents in the three case study suburbs of Southernwood, Cambridge and Gonubie. The interviews focused on three proxy indicators of social capital at neighbourhood level. The results of the study showed that post-apartheid spatial integration in East London closely followed the class-based residential template. Contrary to predictions prior to, and following apartheid‟s demise, the study showed that spatial integration occurred without racial conflicts. The study also found that social integration in the residential suburbs reflected the neighbourhood context and personal preferences, and was highly fluid. Although feelings of racial distance were evident, there were also indications of social cohesion, which were dynamic and uneven in time and space. Based on the data and the dialectical nature of spatial and social integration, the study concluded that fragmentation and integration are likely to continue coexisting in the South African city.

- Description: Plant productivity is greatly affected by environmental stresses such as drought, salinity and insect herbivory. Plants respond and adapt to these stresses by exhibiting physiological as well as biochemical changes at the cellular and molecular levels in order to survive. Expression of a variety of genes which encode numerous membrane transporters have been demonstrated to be induced by these stresses in a variety of plants. The nutritional status of plants is controlled by these transporters, which are regulated by the transcription of the corresponding genes. In spite of these adverse stress effects on agricultural yield, only a few studies have focused on gene transcriptional and translational regulation of membrane transporters during environmental stress situations. Rice, like other plants, contains a number of sucrose transporters encoded by a family of genes. However, detailed knowledge of their roles, localization and regulation during environmental stress conditions is lacking. Bioinformatic tools were used to identify putative cis-acting regulatory elements that may be involved in the regulation of rice and Arabidopsis thaliana sucrose transporters. The possible cis-acting regulatory elements were predicted by scanning genomic sequences 1.5 kbp upstream of the sucrose transporter genes translational start sites, using Plant CARE, PLACE and Genomatix Matinspector professional data bases. Several cis-acting regulatory elements that are associated with plant development, plant hormonal regulation and stress response were identified, and were present in varying frequencies within the 1.5 kbp of 5′ regulatory region. The putative cis-acting regulatory elements that possibly are involved in the expression and regulation of sucrose transporter gene families in rice and Arabidopsis thaliana during cellular development or environmental stress conditions were identified as: A-box, RY, CAT, Pyrimidine-box, Sucrose-box, ABRE, ARF, ERE, GARE, Me-JA, ARE, DRE, GA-motif, GATA, GT-1, MYC, MYB, W-box, and I-box. Expression analysis was used to elucidate the role of rice (Oryza sativa L. cv Nipponbare) sucrose transporter (OsSUT) genes during drought and salinity treatments of three week old rice plants ( at four leaf stage) over a 10 days. Among the five rice OsSUT genes identified, only OsSUT2 was observed to be progressively up-regulated during drought and salinity treatments, while OsSUT1, OsSUT4 and OsSUT5 were expressed at low levels, and OsSUT3 showed no detectable transcript expression. Sucrose transport will be essential to meet the cellular energy demands and also for osmoprotectant activities during drought and salinity stresses. It therefore indicates that OsSUT2 which facilitates transport of sucrose from photosynthetic cells will be III essential for rice plants to cope with drought and salinity stresses, and cultivars with a higher OsSUT2 expression should be able to tolerate these environmental stresses better. The role of OsSUT in assimilate transport during rusty plum aphids (Hysteroneura setariae; Thomas) infestation on the leaves of three week old rice (Orzya sativa L. cv Nipponbare) cultivar plants, over a time-course of 1 to 10 days of treatments, was also examined by combination of gene expression and β-glucuronidase (GUS) reporter gene analysis. Real Time PCR analysis of the five OsSUT genes revealed that the expression of OsSUT1 was progressively up-regulated during the course of aphid infestation. OsSUT2 and OsSUT4 expression were comparatively low in both the control and treated plants. OsSUT5 showed no clear difference in transcript expression in both control and treated plants, while no detectable transcript expression of OsSUT3 could be found. The up-regulation of OsSUT1 gene was verified at protein level by western blot analysis in both the control and treated plants. OsSUT1 protein expression was found to increase with time during aphid infestation. A similar trend was noticeable in the control plants, however at a lower expression level. These demonstrate that the cellular expression of OsSUT1is regulated by both developmental and environmental factors. OsSUT1-promoter:::GUS reporter gene expression was observed within the vascular parenchyma and/or companion cells associated with phloem sieve elements of the large and small bundles in the phloem tissues of the flag leaf blade regions where feeding aphids were confined, which progressively increased with time of infestation. It is suggested that OsSUT1 may primarily play an essential role in phloem transport of assimilate to wounded tissues from adjacent health tissues or may be involved in the retrieval of assimilate back into the phloem to minimize loss caused by the infestation. Some OsSUT1-promoter:::GUS expression was also found in the metaxylem at 10 days after infestation, which could signify a recovery system in which sucrose lost into the xylem as a result of aphids feeding are retrieved back into the phloem through the vascular parenchyma. This was supported by the exposure of cut ends of matured OsSUT1-promoter:::GUS rice plant leaf to 2% sucrose solution. OsSUT1-promoter:::GUS expression was observed within the protoxylem, xylem and phloem parenchyma tissues. This indicates that sucrose translocating within the xylem tissues are retrieved into the phloem via the OsSUT1 localized within the parenchyma tissues. In conclusion, the differential expression and regulation of rice (Orzya sativa L. cv Nipponbare) sucrose transporters as reported here suggest that OsSUT2 and OsSUT1 were constitutively expressed compared to other rice sucrose transporters during drought and salinity, and rusty plum aphids (Hysteroneura setariae; Thomas) infestation stresses respectively. Thus, the expression and regulation of the sucrose transporters could be related to the physiological and nutritional requirements of the cells during plant developmental or environmental stress state that allows their differential expression.

The putative cis-acting regulatory elements that possibly are involved in the expression and regulation of sucrose transporter gene families in rice and Arabidopsis thaliana during cellular development or environmental stress conditions were identified as: A-box, RY, CAT, Pyrimidine-box, Sucrose-box, ABRE, ARF, ERE, GARE, Me-JA, ARE, DRE, GA-motif, GATA, GT-1, MYC, MYB, W-box, and I-box. Expression analysis was used to elucidate the role of rice (Oryza sativa L. cv Nipponbare) sucrose transporter (OsSUT) genes during drought and salinity treatments of three week old rice plants ( at four leaf stage) over a 10 days. Among the five rice OsSUT genes identified, only OsSUT2 was observed to be progressively up-regulated during drought and salinity treatments, while OsSUT1, OsSUT4 and OsSUT5 were expressed at low levels, and OsSUT3 showed no detectable transcript expression. Sucrose transport will be essential to meet the cellular energy demands and also for osmoprotectant activities during drought and salinity stresses. It therefore indicates that OsSUT2 which facilitates transport of sucrose from photosynthetic cells will be III essential for rice plants to cope with drought and salinity stresses, and cultivars with a higher OsSUT2 expression should be able to tolerate these environmental stresses better. The role of OsSUT in assimilate transport during rusty plum aphids (Hysteroneura setariae; Thomas) infestation on the leaves of three week old rice (Orzya sativa L. cv Nipponbare) cultivar plants, over a time-course of 1 to 10 days of treatments, was also examined by combination of gene expression and β-glucuronidase (GUS) reporter gene analysis. Real Time PCR analysis of the five OsSUT genes revealed that the expression of OsSUT1 was progressively up-regulated during the course of aphid infestation. OsSUT2 and OsSUT4 expression were comparatively low in both the control and treated plants. OsSUT5 showed no clear difference in transcript expression in both control and treated plants, while no detectable transcript expression of OsSUT3 could be found. The up-regulation of OsSUT1 gene was verified at protein level by western blot analysis in both the control and treated plants. OsSUT1 protein expression was found to increase with time during aphid infestation. A similar trend was noticeable in the control plants, however at a lower expression level. These demonstrate that the cellular expression of OsSUT1is regulated by both developmental and environmental factors. OsSUT1-promoter:::GUS reporter gene expression was observed within the vascular parenchyma and/or companion cells associated with phloem sieve elements of the large and small bundles in the phloem tissues of the flag leaf blade regions where feeding aphids were confined, which progressively increased with time of infestation. It is suggested that OsSUT1 may primarily play an essential role in phloem transport of assimilate to wounded tissues from adjacent health tissues or may be involved in the retrieval of assimilate back into the phloem to minimize loss caused by the infestation. Some OsSUT1-promoter:::GUS expression was also found in the metaxylem at 10 days after infestation, which could signify a recovery system in which sucrose lost into the xylem as a result of aphids feeding are retrieved back into the phloem through the vascular parenchyma. This was supported by the exposure of cut ends of matured OsSUT1-promoter:::GUS rice plant leaf to 2% sucrose solution. OsSUT1-promoter:::GUS expression was observed within the protoxylem, xylem and phloem parenchyma tissues. This indicates that sucrose translocating within the xylem tissues are retrieved into the phloem via the OsSUT1 localized within the parenchyma tissues. In conclusion, the differential expression and regulation of rice (Orzya sativa L. cv Nipponbare) sucrose transporters as reported here suggest that OsSUT2 and OsSUT1 were constitutively expressed compared to other rice sucrose transporters during drought and salinity, and rusty plum aphids (Hysteroneura setariae; Thomas) infestation stresses respectively. Thus, the expression and regulation of the sucrose transporters could be related to the physiological and nutritional requirements of the cells during plant developmental or environmental stress state that allows their differential expression.

- Description: The land reform that has unfolded in Zimbabwe since 1980 used different models and had diverse consequences. Since the implementation of the fast tract land reform programme in 2000, Zimbabwe experienced heavy reduction in yield and output at farm level that led to a 70% shortfall in production to meet annual food requirements (Richardson, 2005). The economic crisis in Zimbabwe has been characterized by worsening food insecurity especially in the rural areas where harvests continue to be poor. In the beef sector, Zimbabwe has failed to meet its export quota to the EU. The shortfall in production to meet annual food requirements shows a very grim situation but do not tell us about the performance of resettled farmers who now occupy much of the productive land. The broad objective of the study was to determine and compare the production efficiency of resettled farmers in Zimbabwe across land reform models. In addition, the study determined land use intensity. The study was conducted in the Mashonaland Central Province of Zimbabwe mainly because a wide variety of field crops were grown by resettled farmers. The respondents were stratified into three groups. These were: beneficiaries of land reform before 2000 (resettle scheme), fast track A1 model and fast track A2 model. The three models differ on how they were implemented and supported and this might result in different efficiencies of the models. A total of 245 copies structured questionnaire were administered on the resettled farmers from June to September 2010. Descriptive statistics was applied to the basic characteristics of the sampled households. The effect of model of land reform, gender of the household head, marital status, age of the household head, education, household size, religion, dependence ratio, whether the farmer was fulltime or part-time in farming, experience of the farmers in farming at that environment, total land size owned by the farmers and soil type on revenue per hectare and land use rate were determined using the GLM procedure of SAS (2003). Significance differences between least-square group means were compared using the PDIFF test of SAS (2003). The relationship between Revenue and land utilization was examined using the Pearson‟s correlations analysis. Dependance between response variables that had an effect on either revenue per hectare or land utilization with all the other response variables was tested using the Chi-square test for dependance. To find the effect of arable land used and herd size on revenue per hectare and land use the RSREG Procedure of SAS (2003) was used. Input oriented DEA model under the assumption of constant return to scale was used to estimate efficiency in this study. To identify factors that influence efficiency, a Tobit model censored at zero was selected. The mean land use rate varied significantly (p<0.05) with the land reform model with A2 having highest land use rate of 67%. The A1 and old resettlement households had land use rates of 53% and 46%, respectively. Sex, marital status, age of the household head, education and household size significantly affected land use (P<0.05). Revenue per hectare was not affected by any the factors that were inputted in the model. Results from the DEA approach showed that A2 farmers (large land owners) had an average technical efficiency score of 0.839, while the lowest ranking model (A1) had an average score of 0.618. Small land holders (A1 and the old resettled farmers) are on average less cost-efficient than large land owners, with a score of 0.29 for the former compared with 0.45 for the latter. From the factors that were entered in the Tobit model, age of household head, excellent production knowledge and farmer status affected technical efficiency whereas allocative efficiency was only affected by good production knowledge, farm size, arable land owned and area under cultivation. Factors which affected economic efficiency of the resettled farmers are secondary education, household size, farm size, cultivated area and arable land owned. None of the included socio-economic variables has significant effects on the allocative and economic efficiency of the resettled farmers. Thus, the allocative and economic inefficiencies of the farmers might be accounted for by other natural and environmental factors which were not captured in the model.

- Description: This study investigates the impact of informal cross border trading on poverty reduction in Zimbabwe. In the context of this study, the term Informal Cross Border Trade (ICBT), is used to describe the activities of small entrepreneurs who are involved in buying and selling across national borders. The study focuses on whether the stated activities are lifting those participating out of poverty. The research problem is examined through an assessment of the income levels, assets acquirement, expenditures patterns, food security and family relations. The hypotheses tested in the research are that, “The extent of ICBT is significant in Zimbabwe; ICBT in the Southern Africa region is mainly dominated by women; and that ICBT contributes positively to poverty reduction”. In this context, poverty reduction is said to have occurred when informal cross border trading would have resulted in an improvement in the socio-economic wellbeing of traders‟ households. The Poverty Datum Line (PDL) is used as the measure of households‟ well-being. To assess the impact of ICBT on well-being, a survey was conducted whereby in-depth interviews using the questionnaire method were used to collect primary data. Secondary information was obtained from documentary searches at institutions and also using internet searches. From this study it has been found that ICBT has both positive and negative impacts with regard to social welfare. With regard to economic welfare, based on poverty indicator measures used in the study, ICBT contributes positively to Poverty Reduction. Thus the analysis revealed that informal cross border trade plays an important role in alleviating economic hardships, reducing poverty and enhancing welfare and human development in Zimbabwe.

- Description: China, the largest aluminium producer, is seriously lacking of reserves at the present and in the future. However, there are a huge amount of sub-economic aluminium resources (high iron diasporic, low A/S and high iron gibbsite and high sulfur diasporic bauxite), and potassic sandy shale suitable for the extraction of aluminium and the production of potassium and silicon fertilizers if proper metallurgical processes are developed. This study aims to investigate the sub-economic aluminium resources through investigation and identify the right technologies through laboratory tests for metal extraction and utilization of the by-products of K-feldspar sandy shale. The investigation of the sub-economic aluminium resources includes field and site visits and data collection and collation. A series of laboratory scale tests were carried out for different types of bauxite and potassic sandy shale, which includes initial try tests and formal laboratory experiments for optimization of the processes and procedures, and crop planting tests for use of potassium and silicon fertilizers. The successful laboratory tests (technologies) in this study were optimized and proved to be effective. The results showed: 1) Medium temperature metallization roasting and then magnetic separation, and gas reduction metallization roasting and then magnetic separation are effective for processing of the high iron diasporic bauxite; 2) Dry magnetic separation, wet magnetic separation and medium temperature magnetization roasting and then magnetic separation are not effective for processing of the high iron diasporic bauxite; 3) Digestion at atmospheric conditions and high caustic alkali concentration is effective for processing of low A/S and high iron gibbsite bauxite; 4) Desulfurization flotation and desulfurization with barium aluminate are both effective for processing of the high sulfur bauxite. However, each of these methods have their own advantages and disadvantages and must be evaluated; and 5) The soda-lime sintering process is suitable for processing of the Linzhou potassic sandy shale. The aluminium and potassium are extracted and the silicon residues can be used for silicon fertilizer. The results of this study help solve the problem of aluminium reserve shortage. They also open a new way for integrated utilization of other aluminium resources including potassic sandy shale.

- Description: The apparent reversal of trend from modern drugs to herbal medicine is partly due to the fact that synthetic drugs have always shown adverse reactions and other undesirable side effects. Hence, the use of medicinal plants for the treatment of diseases such as diabetes is very common especially in the rural areas. Majority of these plants are used based on the experience and indigenous knowledge without identification of the therapeutic agents. There is enormous wealth of medicinal plants in the world yet many of them have not been discovered or studied scientifically to substantiate their ethno-medicinal usages. Ethnobotanical study has been the method often used to search for locally important plant species for the discovery of crude drugs with low side effects. An ethnobotanical survey was conducted on the medicinal plants commonly used for the management of diabetes mellitus in Nkonkobe Municipality, Eastern Cape of South Africa. Information was obtained through structured questionnaire administered to traditional healers and herbalists in the region. The study revealed 15 species of plants belonging to 13 families. Strychnos henningsii and Leonotis leonorus among others were repeatedly mentioned by the traditional healers as the two mostly used plants for the management of diabetes mellitus. The infusion and decoction of the roots, leaves and barks of these plants are the methods of preparation. The antioxidant potential of aqueous bark extract of S. henningsii was investigated both in vivo and in vitro using spectroscopic method. The antioxidant activity of the extract against hydrogen peroxide (H2O2), 2,2′-azinobis[3-ethylbenzothiazoline6-sulfonic acid] diammonium salt (ABTS), as well as reducing power was concentration dependent. The extract exhibited lower and average scavenging activities against 1,1diphenyl2picrylhydrazyl (DPPH) and nitric oxide (NO) radicals with IC50 value of 0.739 and 0.49 mg/ml respectively. The administration of the plant extract at 250, 500 and 1000 mg/kg significantly increased the activities of the antioxidant enzymes in the hepatotoxic rats induced with carbon tetrachloride. On the other hand, the stem bark extract had lower effect on lipid peroxidation level except at the dose of 250 mg/kg. The effect of oral administration of S. henningsii extract was evaluated in normal Wistar rats for 28 days. The observed result indicated non- toxic effect of sub-acute administration of plant extract to the animals except at certain doses. This is because, there was no apparent damage to some haematological and biochemical parameters used in assessing organ specific toxicity. However, the alterations observed on platelet, white blood cells and its differentials imply parameter and dose selective toxicity when repeatedly consumed on daily basis at the doses investigated. This study also investigated the antidiabetic activities of the extract at the doses of 125, 250 and 500 mg/kg body weight in diabetic rats induced with streptozotocin -nicotinamide for 15 days. The extract appreciably (P <0.05) reduced the blood glucose level, feed and water intake while the best result was obtained at 250 mg/kg. Similarly, the level of triacylglycerol at the three doses investigated was significantly decreased. In addition, the glucose tolerance was reduced to near normal level after 90 min at certain doses. The clinical significance of the extract on some biochemical and haematological parameters lessen both hepatic and renal damages. Anaemic condition in diabetic animals was also improved after plant extract administration. However, no significant effect was observed in white blood cells and some of its differentials. The extract demonstrated strong glucose utilization in 3T3-L1 cells with a response of 278.63 percent of the control at 12.5μg/ml while that of Chang liver cells was 103.54 percent. The cytotoxicity result revealed non toxic effects of the extract to both cell lines. Treatment of 3T3 L1 cells with the extract did not reduce lipid accumulation. The extract inhibited the activity of α- glucosidase and α- amylase in a concentration dependent manner with IC50 values of 38 μg/ml and 60.9 μg/ml respectively. The percentage protein antiglycation of S. henningsii was 18.4, 38.2 and 61.2 perceent for 0.25, 0.5 and 1 mg/ml respectively while aminoguanidine a known inhibitor of protein glycation was 87.2 percent at 1 mg/ml. The FRAP assay values of the extract was 357.05 μmol Fe (II)/g. The findings from this study support the folkloric usage of this plant for the management of diabetes mellitus in the region.

- Description: Medicinal plants have been used as traditional medicine in the treatment of numerous human diseases for thousands of years in many parts of the world. In the developing world, especially in rural areas, herbal remedies continue to be a primary source of medicine. Scientifically, medicinal plants have proven to be an abundant source of biologically active compounds, many of which have already been formulated into useful therapeutic substances or have provided a basis for the development of new lead molecules for pharmaceuticals. Antibiotic resistance, undesireable side effects and expences associated with the use of combination therapy in the treatment of Helicobacter pylori infections have generated a considerable interest in the study of medicinal plants as potential sources of new drugs against this organism. The high complexicity of bioactive compounds accumulated in plants coupled with their broad antimicrobial activity may make it difficult for pathogenic organisms, including H. pylori to acquire resistance during treatment. This study therefore evaluates the antimicrobial potential of selected South African medicinal plants employed in the treatment of H. pylori-related infections, and the subsequent isolation of the plant active principles. An ethnobotanical survey of plants used in the treatment of H. pylori-related infections was conducted in the study area. Crude extracts of Combretum molle, Sclerocarya birrea, Garcinia kola, Alepidea amatymbica and 2 Strychnos species were screened against 30 clinical strains of H. pylori and 2 standard control strains (NCTC 11638 and ATCC 43526). In the preliminary stages of this study, ethyl acetate, acetone, ethanol, methanol and water extracts of the plants were tested against H. pylori by agar well diffusion and micro broth dilution methods. The plant crude extracts that exhibited anti-H. pylori activity with a iv percentage susceptibility of 50 percent and above were considered for the rate of kill assays and the most active crude extracts selected for bio-assay guided isolation of the active ingredient. Preliminary fractionation of the crude extract was achieved by thin layer chromatography (TLC) using different solvent combinations; hexane/diethylether (HDE), ethyl acetate/methanol/water (EMW) and chloroform/ethyl acetate/formic acid (CEF) in order to determine the most suitable combination for column chromatography (CC) and subsequent testing by indirect bioautography. The extract was then fractionated in a silica gel column using previously determined solvent combinations as eluent. Active fractions obtained from column chromatography separations were further fractionated and the compounds identified by gas chromatography/mass spectrometry (GC/MS) analysis. All the plants exhibited antimicrobial activity against H. pylori with zone of inhibition diameters ranging from 0 - 38 mm and minimum inhibitory concentration (MIC) values ranging from 0.06 - 5.0 mg/mL. The most active plant extracts were the acetone extract of C. molle with a percentage susceptibility of 87.1 percent, acetone and aqueous extracts of S. birrea (71 percent each) and the ethanolic extracts of G. kola (53.3 percent). Except for the aqueous extract, these extracts also exhibited a strong bactericidal activity against H. pylori at different concentrations. TLC analysis revealed the presence of 9 components in the acetone extract of S. birrea with the EMW solvent system as opposed to 5 and 8 with HDE and CEF respectively. Bioassay-guided isolation led to the identification of 52 compounds from the acetone extract of S. birrea with n-octacosane being the most abundant (41.68 percent). This was followed by pyrrolidine (38.91 percent), terpinen-4-ol (38.3 percent), n-eicosane (24.98 percent), cyclopentane (16.76 percent), n-triacontane (16.28 percent), aromadendrene (13.63 percent) and α-gujunene (8.77 percent). Terpinen-4-ol and pyrrolidine demonstrated strong antimicrobial activity against H. pylori at all concentrations tested. These results may serve as preliminary scientific validation of the ethnomedicinal uses of the above mentioned plants in the treatment of H. pylori-related infections in South Africa. Terpinen-4-ol and pyrrolidine could be considered for further evaluation as therapeutic or prophylactic agents in the treatment of H. pylori-related infections. However, further investigations would be necessary to determine their toxicological properties, in-vivo potencies and mechanism of action against H.pylori

- Description: Medicinal plants have been used as traditional medicine in the treatment of numerous human diseases for thousands of years in many parts of the world.

- Description: This study was about the reaction of disadvantaged groups and persons to inequality and deprivation. Set in Badia, a low income community in Lagos, Nigeria, it investigates the main effects of community members’ attributions of causes of poverty in motivating or impeding their reaction to inequality. Relative Deprivation (RD) theory proposed that dissatisfaction with social outcomes depend on subjective feelings rather than objective criteria. However scholars found empirical difficulties in predicting collective action on the basis of RD. Resource Mobilization proponents argued on the contrary that feelings are not salient within the framework of action. The infusion of Social Identity Theory (SIT) into RD research however resolved the paradox of action with SIT’s argument that action was contingent upon the perception of permeability and legitimacy of inter-group structures. However, despite successes of SIT, scholars found that it was unable to predict the type of actions group members will take in response to injustice and the nature of possible actions. Propositions of RD and SIT were therefore suitable for integration into the proposition of Taylor & McKirnan’s (1984) Five Stage Model (FSM) of inter-group relations that reactions to RD feelings were predicated upon the dynamics of the social philosophy guiding stratification. Using an integrated RD, SIT and FSM framework, this study shows how disadvantaged group members’ responses to deprivation proceeded as predicted by the FSM from mutual acceptance to collective action mediated by their perception of causes of poverty. This complements the trend in the literature on reaction to inequality and it's almost ii exclusive focus on instrumental and affective concerns while neglecting the role of consensually shared beliefs in motivating or impeding action and willingness to act in response to injustice. The study hypothesized that the pattern of causal attributions of poverty of respondents will shape their ‘predisposition to act’ and the type of action they would engage in. The main hypothesis of the study therefore was that poverty attribution mediates the relationship between ‘feelings of injustice’ and ‘reaction to inequality’. For instance where respondents attribute poverty to individual or fatalistic factors they will adopt individual action whereas where attributions are structural, responses will be collective, where feelings of injustice were present. A survey was conducted using a five-level Likert scale to decipher respondents’ perceptions of feelings of injustice, their causal attribution of poverty, their levels of willingness to embark on collective action and actions taken in the preceding year. In the first stage of analysis, responses (n = 383) were reduced using Principal Components Analysis (PCA) to determine how questionnaire items contributed to variables under consideration. Subsequently, variables extracted were correlated and regressed. While bivariate correlation was used to test simple relationships between variables, a stepwise hierarchical regression analysis was used to decipher how sub-dimensions of poverty attribution mediate the relationship between respondents’ feelings of injustice and their willingness to embark on collective action entering variables in succession into the regression equation. Furthermore, a 1 x 3 x 5 Multivariate Analysis of Covariance (MANCOVA) was used to test the mediation effects of poverty attribution sub-dimensions on the relationship between injustice feelings and actions. The results showed iii that structural attribution was the preferred explanation for poverty among Badia residents, as this explanation was preferred by a majority of the respondents. It was also shown that while 96.9% of respondents used more than one causal attribution, a majority of structural attributors adopted fatalistic attribution as second choice of explanation for poverty. On the basis of the above, and in line with previous studies (Mann, 1970; Bobo, 1991), it was deduced that the possibility for radical action would be diminished as a result of this ‘dual/split consciousness’. The result further confirmed as hypothesized, that fatalistic attribution had a negative correlation with willingness to embark on collective action as respondents in the fatalistic condition were not willing to embark on collective action. However, respondents in the structural conditions were more willing to engage in collective action. While attributions predicted willingness to embark on collective action, MANCOVA showed that action proceeded in a continuum as predicted by the FSM. For example, while the introduction of fatalistic and individual attribution to the equation hypothesizing the relationship between injustice feelings and action showed that resultant actions were predominantly individual normative, post-hoc inclusion of the structural dimension to the equation showed an addition variance to the equation for collective action. This indicated that structural attributions enhance collective normative action. However, consistent with most studies in the literature, the results did not predict collective non-normative action1. Results indicated low adherence of subject to items eliciting collective action suggesting that past studies which reported high preference of collective action by disadvantaged groups may have been influenced by ‘social desirability effects’, given Topf’s (1995) assertion that what people say they will do is often not what they do but what they perceive as right in the particular situation. 1 The only notable exception is Boen & Vanbeselaere (1998) 2 A full discussion of lay explanations of poverty is reserved for chapter 4 of this thesis. iv The study however proposed on the basis of the salience of structural attributions that poverty attributions may become useful for Social Movement Organizations (SMOs) interested in fostering social change. However, while the study showed that attribution influences willingness to embark on action it does not show how attribution becomes salient in group membership. Thus there is a need for future studies to investigate how attribution affects group identification. Similarly, given the dearth of studies of the attribution of the ‘actual poor’ of poverty, it is necessary for future studies to test the validity of the result from the present study indicating stronger adherence to fatalistic than individualistic attributions of poverty among the disadvantaged. While many past studies of attribution and those of reaction to injustice have been on samples of middle-class adults in developed countries, or artificially created deprived groups, the present study being of the ‘real life’ poor in a Third World setting, provides evidence of ‘real world’ actions and attributions of people experiencing poverty.

- Description: The need to reduce the cost of adsorption technology has led scientists to explore the use of many low cost adsorbents especially those from renewable resources. Lignocellulose and montmorillonite clay have been identified as potentially low cost and efficient adsorbent materials for the removal of toxic heavy metals and organic substances from contaminated water. Montmorillonite clay has good adsorption properties and the potential for ion exchange. Lignocellulose possesses many hydroxyl, carbonyl and phenyl groups and therefore, both montmorillonite and lignocellulose are good candidates for the development of effective and low cost adsorbents in water treatment and purification. The aim of this study was to prepare composite materials based on lignocellulose and montmorillonite clay and subsequently evaluate their efficacy as adsorbents for heavy metal species and organic pollutants in aqueous solution. It was also important to assess the adsorption properties of the modified individual (uncombined) lignocellulose and montmorillonite. Lignocellulose and sodium-exchanged montmorillonite (NaMMT) clay were each separately modified with methyl methacrylate (MMA), methacrylic acid (MAA) and methacryloxypropyl trimethoxysilane (MPS) and used as adsorbents for the removal of heavy metals and dyes from aqueous solution. The lignocellulose and NaMMT were modified with MMA, MAA and MPS through free radical graft polymerisation and/or condensation reactions. NaMMT was also modified through Al-pillaring to give AlpMMT. The materials were characterised by fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and small angle X-ray scattering (SAXS) and characterisation results showed that the modification of the montmorillonite with MAA, MMA and MPS was successful. The modified lignocellulose and montmorillonite materials were evaluated for the adsorption of heavy metal ions (Cd2+ and Pb2+) from aqueous solution by the batch method. The adsorption isotherms and kinetics of both Cd2+ and Pb2+ onto the NaMMT clay, AlpMMT and lignocellulose materials are presented. The Langmuir isotherm was found to be the best fit for the adsorption of both heavy metals onto all the adsorbents. AlpMMT showed very poor uptake for heavy metals (both Cd2+ and Pb2+). PMMAgMMT, PMAAgMMT, PMAAgLig and PMPSgLig showed improved adsorption for both heavy metals. The mechanism of heavy metal adsorption onto the adsorbents was best represented by the pseudo second-order kinetic model. PMPSgLig, NaMMT and AlpMMT showed relatively high adsorption capacities for methyl orange, while the adsorption of neutral red was comparable for almost all the adsorbents. Neither the Langmuir model nor the Freundlich model was found to v adequately describe the adsorption process of dyes onto all the adsorbents. The pseudo second-order model was found to be the best fit to describe the adsorption mechanism of both dyes onto all the adsorbents. The modification of lignocellulose and montmorillonite with suitable organic groups can potentially produce highly effective and efficient adsorbents for the removal of both heavy metals and dyes from contaminated water. Novel adsorbent composite materials based on lignocellulose and montmorillonite clay (NaMMT) were also prepared and evaluated for the removal of pollutants (dyes and heavy metals) from aqueous solution. The lignocellulose-montmorillonite composites were prepared by in situ intercalative polymerisation, using methyl methacrylate, methacrylic acid and methacryloxypropyl trimethoxysilane (MPS) as coupling agents. The composite materials were characterised by FTIR, TGA, TEM and SAXS. SAXS diffractograms showed intercalated nanocomposites of PMMAgLig-NaMMT and PMAAgLig-NaMMT, whereas PMPSgLig-NaMMT showed a phase-separated composite and the same results were confirmed by TEM. The lignocellulose-montmorillonite composites were assessed for their adsorption properties for heavy metal ions (Cd2+ and Pb2+) and dyes (methyl orange and neutral red) from aqueous solution. Among these composite materials, only PMAAgLig-NaMMT showed a marked increase in the uptake of both Cd2+ and Pb2+ relative to lignocellulose and montmorillonite when used independently. The adsorption data were fitted to the Langmuir and Freundlich isotherms, as well as to the pseudo first-order and pseudo second-order kinetic models. The data were best described by the Langmuir isotherm and the pseudo second-order kinetic model. On the adsorption of dyes, only PMPSgLig-NaMMT showed enhanced adsorption of methyl orange (MetO) compared with lignocellulose and montmorillonite separately. The enhanced adsorption was attributed to the synergistic adsorption due to the presence of MPS, lignocellulose and NaMMT. Competitive adsorption studies were carried out from binary mixtures of MetO and Cd2+ or Pb2+ in aqueous solution. The adsorption process of MetO onto the composite material was found to follow the Freundlich adsorption model, while the mechanism of adsorption followed both the pseudo first-order and pseudo second-order models. This particular composite can be used for the simultaneous adsorption of both heavy metals and organic dyes from contaminated water. The adsorption of neutral red to the composite materials was comparable and the pseudo second-order kinetic model best described the adsorption mechanism.

- Description: Adolescents in the schools in South Africa have been victims of many social problems such as violence and crime as a result of background influence. They have been both victims and perpetrators of this violence. Problems of attachment to both school and home have always been blamed for the adolescents’ deviance. South African schools are affected by this verbal and physical violence which presumably emanates from learners poor connections with school and home. The background of societies such as economic deprivation has also been presumed to have an impact on the way adolescents conduct themselves in schools. There is no research that has verified the correlation between violence and attachment to bases of attachment - home and school in South Africa, especially in the Eastern Cape Province. A survey was conducted in more than ten schools in the Amathole District where 317 learners’ opinions on their observation of cases of verbal and physical violence in their schools, and on their attachment to both home and school were collected through a 40 item questionnaire. The questionnaire had five sections (a) to (e). The first section (a) required learners to enter their biographical information; gender, age, grade, and quintile classification. The second section (b) required learners to rate their attachment to their homes and to their care givers. The third section (c) required learners to rate their connectedness to their schools. The fourth section (d) required learners to supply information on their observation and involvement in verbal violence. The final section (e) with items adopted from section (d) and customised required learners to rate their observation and involvement in physical violence. Descriptive statistics were used to glean frequencies and the overall levels of attachment and violence amongst learners. The study also looked at significant differences in attachment (both family and school) and violence (both verbal and physical) using gender and socio-economic profiles of the learners and schools (quintile system) as sorting or categorising variables. One major finding which is contrary to most theory and may be as a result of social dynamics is that statistics suggested that gender and socio-economic variables had little bearing on violence and attachment. Through the use of SPSS, the Spearman’s rho correlation coefficients were calculated to answer the sub-questions on the relationship between family and school attachment, and school violence (both verbal and physical). There were notable negative and positive correlations between school attachment and verbal violence; for example there was a positive correlation between teachers making learners hate school and learner-involvement in swearing. There was also a negative correlation between school buildings making learners proud and schools and homes being to blame for the frequency of verbal violence in the schools. There were also notable correlations between attachment to family and verbal violence such as the correlation between the frustration by parents’ lack of concern and learners’ involvement in verbal violence without any clear reason. With regard to physical violence there was a negative correlation between parents having time to discuss life with their children and the frequency of physical violence in the schools. There was however a negative correlation between one’s pride in one’s school and the blame on schools for instigating school violence. From these correlations implications for school violence prevention could be drawn. The study reveals that a lot needs to be done by the schools, parents, the government, and the community to enhance learner attachment to both school and home. However, for all the stake holders to succeed government must take the leading role in speeding up the process of reducing poverty in the communities. This is premised on the fact that some findings reveal that frequency of violence increases in an environment of frustration and anger. Schools as care-givers can also introduce many interventions such as counselling workshops to equip teachers with professional crisis management. The research may encourage the Department of Education and schools to adopt violence prevention programs implemented in countries (like United States of America’s Olweus bullying and violence prevention program) for use in bringing communities together to work against school violence. These findings might strengthen the South African Department of Education’s Safe Schools Programs.

- Description: Adolescents in the schools in South Africa have been victims of many social problems such as violence and crime as a result of background influence. They have been both victims and perpetrators of this violence. Problems of attachment to both school and home have always been blamed for the adolescents’ deviance. South African schools are affected by this verbal and physical violence which presumably emanates from learners poor connections with school and home. The background of societies such as economic deprivation has also been presumed to have an impact on the way adolescents conduct themselves in schools. There is no research that has verified the correlation between violence and attachment to bases of attachment - home and school in South Africa, especially in the Eastern Cape Province. A survey was conducted in more than ten schools in the Amathole District where 317 learners’ opinions on their observation of cases of verbal and physical violence in their schools, and on their attachment to both home and school were collected through a 40 item questionnaire. The questionnaire had five sections (a) to (e). The first section (a) required learners to enter their biographical information; gender, age, grade, and quintile classification. The second section (b) required learners to rate their attachment to their homes and to their care givers. The third section (c) required learners to rate their connectedness to their schools. The fourth section (d) required learners to supply information on their observation and involvement in verbal violence. The final section (e) with items adopted from section (d) and customised required learners to rate their observation and involvement in physical violence. Descriptive statistics were used to glean frequencies and the overall levels of attachment and violence amongst learners. The study also looked at significant differences in attachment (both family and school) and violence (both verbal and physical) using gender and socio-economic profiles of the learners and schools (quintile system) as sorting or categorising variables. One major finding which is contrary to most theory and may be as a result of social dynamics is that statistics suggested that gender and socio-economic variables had little bearing on violence and attachment. Through the use of SPSS, the Spearman’s rho correlation coefficients were calculated to answer the sub-questions on the relationship between family and school attachment, and school violence (both verbal and physical).

- Description: Death and bereavement are prevalent in Zimbabwe due to HIV/AIDS and other illnesses. It is estimated that a large population of school going learners have lost one or both parents and have become orphans. The aim of the study was two-fold: to understand the bereavement experiences of orphaned learners and to examine how such experiences can inform school counselling services. A multiple case study involving 13 school children and four school counsellors from two secondary schools in Harare Metropolitan Region was conducted. Each of the 17 participants was viewed as a bounded case due to his or her individual unique experiences. An interpretive phenomenological approach was employed to collect and analyse the data. All the cases were purposively selected as they were bearers of crucial information on bereavement experiences and bereavement counselling. The study established nine (9) key findings. First, it was found that the type of attachments and support systems the child had were contributory to the way the child experienced bereavement. Second, it was established that although learners manifested emotional pain, they found it difficult to verbalise it. Third, the study found that cultural practices either exacerbate or work for the better for bereaved children as some were seen to enhance their livelihood whilst some were detrimental and oppressive. Fourth, it was established that bereavement triggered philosophical and reflexive reactions on the part of bereaved children. The deaths of the parents resulted in them reflecting on the three phases of their life trajectories: life before death; at the time of death; and after death. Fifth, it was also established in the study that there was a mismatch in what children and counsellors claimed to be happening in secondary schools pertaining bereavement counselling provisioning. Sixth, the study found that most children did not receive any bereavement counselling in schools. Only three out of the 13 learner cases interviewed in this study had a teacher in the school talk to them about loss of their parents. In some instances, a child’s bereavement was only discovered through the grapevine or when this researcher got to the school. Seventh, it was established that although counsellors were qualified as both teachers and counsellors, they lacked confidence in dealing with sensitive issues such as bereavement. Eighth, the study also found that although there is a lot of death in Zimbabwe the counselling syllabi lacked focus on bereavement counselling. Ninth, it was also discovered that teachers who were not assigned to counselling duties had negative attitudes towards counselling, a matter which has serious consequences for the bereaved learners. Based on the above findings, the study concludes that bereaved children experienced a variety of circumstances that impacted both positively and negatively on their schooling and rendered them in need of bereavement counselling. It also concludes that bereaved learners in selected Harare schools were not receiving adequate bereavement counselling; schools neither had policies nor laid down procedures on bereavement counselling. For further research, the study recommends that there should be research focusing on methodologies designed to access children’s innermost feelings of emotional pain. There should be further research on the nature of the relationship between a child’s bereavement and educational experiences. Studies involving other bereaved populations, such as, children from rural areas and primary school children should be carried out in order to gain insights on how the phenomenon is experienced by different age groups in different contexts. To improve counselling practice in schools, the study recommends that there should be capacity building programmes aimed at assisting teachers to deal with bereavement counselling. School bereavement counselling should explore collaboration with other stakeholders such as peers, care givers and government as well as non-governmental organisations. Above all, the study recommends that schools should be proactive and have school bereavement policies and procedures on bereavement counselling.

Social policy and the state in South Africa: pathways for human capability development

- Description: The main focus of this thesis is the challenges that are facing social policy development and implementation in South Africa in relation to the enhancement of human capability. The study adopted a historical approach to assess the model of social policy in South Africa and identified that social relations of domination inherited from the apartheid era continuing to produce inequalities in opportunities. Social policy under the democratic government has not managed to address social inequalities and the main drivers of poverty in the form of income poverty, asset poverty and capability poverty which are the underlying factors reproducing deprivation and destitution of the majority of the population Although South Africa prides itself of a stable democracy, social inequalities continue to undermine the benefits of social citizenship because political participation in the midst of unequal access to economic and social resources undermine the value of citizenship. Also, inequalities in the distribution of income and wealth, and in the control of economic production undermine political equality which is an ethic upon which social rights are predicated. As a result, state interventions are lacking inherent potential to build human capability for people to live the life that they have reason to value. The paradox of social policy in South Africa is that the majority of those who are marginalised are those who were excluded by the apartheid regime even though state intervention is claimed to be targeting them. This points to the failure of incremental equalisation of opportunities within a context of stark social inequities. It is also an indication that the economic growth path delivered by the political transition is working to reinforce the inherited legacy of deprivation and it is avoiding questions related to the structural nature of poverty and inequalities. Therefore, a transformative social policy is an imperative for South Africa. Such a framework of social policy should be premised upon a notion of human security in order to built human capability. Human security focuses on the security of individuals and communities to strengthen human development. It emphasises on civil, political and socioeconomic rights for individual citizens to participate fully in the process of governance. Although this thesis is a case study of social policy in South Africa, it can be used to appreciate the role of social policy in other developing countries, particularly the impact of political decision making on social distribution. Poverty and social inequalities are growing problems in developing countries and so is the importance of putting these problems under the spotlight for political attention.

- Description: The Republic of South Africa emerged as 'a product of a historical moment' and also as a reaction against imperialism, colonialism, racial discrimination and domination over the majority of black South Africans by the white minority. The democratic dispensation came into being also for the first time in its life in memorial for a long turbulent history followed by the general democratic elections held on 27th April 1994. The 1994 first general election liberated South Africa from the apartheid system and its subsequent primary objective was “… to transform South Africa into a non-racial and democratic society”. The new democratic government now looks politically different from the racist regime because the current government since 1994 has been, and to date still is, a truly and broadly representative of the South African citizens and also a transparent one, whereas the defunct apartheid government was characterized primarily by, among other things, the violation of human rights, denying black South Africans of any rights of basic services, no rights of owning property or land, no freedom of association and speeches and firmly practised discrimination which was detrimental to the majority of the black population groups in this country. According to the then President Nelson Mandela whilst addressing the ANC masses that were commemorating the eighty-third (83rd) anniversary of the African National Congress on the 8th January 1995, democracy entails “… a thorough-going process of transformation, of overcoming the political, social and economic legacy of apartheid colonialism, of racism, sexism and class oppression.” The government is still grappling with the challenge of ensuringa better life for all the citizens of this country (http://www.anc.org.za/show.php?doc=ancdocs/history/jan8-95html:1).
