- Description: The main aim of the study was to investigate sexual relationships among gay students at the University of Fort Hare (Alice Campus), Eastern Cape. A qualitative research design was followed and semi-structured interview schedules were issued to twelve participants. The queer theory underpinned this study and it is based on the notion that individuals are able to determine their sexual identity and sexual orientation as they are. The participants, aged 18-25 years, were purposively selected to share their sexual behaviour as gays. The ethical principles such as informed consent, confidentiality, privacy and protection from harm, were adhered to, throughout the study. Prior identification of the themes, coding took place. The following themes were very important in the research and they helped to achieve the aim of the study and they are; challenges gay students experience in their relationships, closet partners, social networks sexual partners among gay students, condom use among gay students, sexual agreements among gay students, condom use, condom self-efficacy, honesty and communication, social support, self-esteem, liberal community and non-homophobic, traditional male circumcision, sexual agreements among gay students ,pornography viewing , sexual abuse among gay students, discrimination in residence, religiosity and perception towards marriage among gay students. Based on the findings, it is recommended that there should be communication among gay couples to avoid lot of conflicts. Also, there should be education about homosexuality in communities, schools and tertiary institutions as many people treat gays badly owing to lack of knowledge

- Description: The genome is the complete set of an organism's hereditary information that contains all the information necessary for the functioning of that organism. Complete nuclear, mitochondrial and plastid DNA constitute the three main types of genomes which play interconnected roles in an organism. Genome sequencing enables researchers to understand the regulation and expression of the various genes and the proteins they encode. It allows researchers to extract and analyse genes of interests for a variety of studies including molecular, biotechnological, bioinformatics and conservation and evolutionary studies. Genome sequencing of Rhodophyta has received little attention. To date, no published studies are focusing on both whole genome sequencing and sequencing of the organellar genomes of Rhodophyta species found in along the South African coastline. This study focused on genome sequencing, assembly and annotation mitochondrial and plastid genomes of Gelidium pristoides. Gelidium pristoides was collected from Kenton-on-Sea and was morphologically identified at Rhodes University. Its genomic DNA was extracted using the Nucleospin® Plant II kit and quantified using Qubit 2.0, Nanodrop and 1% agarose gel electrophoresis. The Ion Plus Fragment Library kit was used for the preparation of a 600 bp library, which was sequenced in two separate runs through the Ion S5 platform. The produced reads were quality-controlled through the Ion Torrent server version 5.6. and assessed using the FASTQC program. The SPAdes version 3.11.1 assembler was used to assemble the quality-controlled reads, and the resultant genome assembly was quality-assessed using the QUAST 4.1 software. The mitochondrial genome was selected from the produced Gelidium pristoides draft genome using mitochondrial genomes of other Gelidiales as search queries on the local BLAST algorithm of the BioEdit software. Contigs matching the organellar genomes were ordered according to the mitochondrial genomes of other Gelidiales using the trial version of Geneious R11.12 software. The plastid genome was also selected following the same approach but using plastid genomes of Gelidium elegans and Gelidium vagum as search queries. Gaps observed in the organellar genomes were closed by amplification of the relevant gap using polymerase chain reaction with newly designed primers and Sanger sequencing. Open reading frames for both organellar genomes were annotated using the NCBI ORF-Finder and alignments obtained from BlastN and BlastX searches from the NCBI database, while the tRNAs and rRNAs were identified using the tRNAscan-SE1.21 vi and the RNAmmer 1.2 servers. The circular physical map of the mitochondrial genome was constructed using the CGView server. Lastly, in silico analysis of cytochrome c oxidase 3 and Heat Shock Protein 70 was performed using the PRIMO and the SWISS-MODEL pipelines respectively. Their phylogenies were analysed through Clustal omega and the trees viewed on TreeView 1.6.6 software. Qubit and Nanodrop genomic DNA qualification revealed A260/A280 and A230/A260 ratios of 1.81 and 1.52 respectively. The 1% agarose gel electrophoresis further confirmed the good quality of the genomic DNA used for library preparation and sequencing. Pre-assembly quality control of reads resulted in a total of 30 792 074 high-quality reads which were assembled into a total of 94140 contigs, making up an estimated genome length of 217.06 Mb. The largest contig covered up to 13.17 kb of the draft genome, and an N50 statistic value of 3.17 kb was obtained. The G.pristoides mitochondrial genome mapped into a circular molecule of 25012 bp, with an overall GC content of 31.04% and a total of 45 genes distributed into 20 tRNA-coding, 2 rRNAcoding genes and 23 protein-coding genes, mostly adopting the modified genetic code of Rhodophyta. The SecY and rps12 genes overlapped by 41 bp. This study presents a partial plastid genome composed of 89 (38%) fully annotated genes, of which 71 are protein-coding, and 18 are distributed among 15 tRNA-coding, 2 rRNA-coding and 1 RNaseP RNA-coding genes. Sixty-one (26%) partial protein-coding genes were predicted, while approximately 84 (36%) genes are not yet predicted. In silico analysis of the cytochrome c oxidase and heat shock protein 70 showed that the gene sequences obtained in this study and the resultant transcribed protein have sequences and structures that are similar to those from several other different species, thus validating the integrity of the genome sequences. This study provides genomic data necessary for understanding the genomic constituent of G.pristoides and serve as a foundation for studies of individual genes and for resolving evolutionary relationships.

- Description: The study sought to investigate the impact of public libraries in developing information literacy in libraries in the Eastern Cape Province of South Africa: a case study of Buffalo City Municipality public libraries in King William’s Town. The objectives of the study were to find out how these three libraries in Buffalo City Metro public libraries ensure equity of library and information services provision to the user communities, to find out how public libraries support education and lifelong learning, to identify the challenges that public libraries face in rendering library and information services with reference to the three libraries, and to investigate the role of library professionals in marketing the library services to the community. Both quantitative and qualitative research methodologies were employed in a descriptive survey. The main research instrument was a questionnaire supported by face to face interviews. A total of 297 questionnaires were distributed and 200 were returned giving a response rate of 67.3%. The quantitative data which was collected through questionnaire was presented using graphs and tables, while qualitative was analysed manually by content analysis, using the notes that were taken by the researcher from the respondents during the interview sessions and reported verbatim in some instances. The findings showed that regardless of South African LIS environment having contradictions resulting from years of apartheid, most of the Buffalo City Metro public library patrons indicated that they experienced fair and equitable access to library and information services. In addition to participants’ quantitative responses, the qualitative excerpts from librarians attested to the library having a classification system that allows easy access to library resources. In addition, findings of the study also revealed that the Buffalo City Metro public libraries have a diversity of users, ranging from different age groups and social standing. The results from the current study revealed that the Buffalo City metropolitan public library users have little knowledge about literacy programmes that are taking place in the library. The findings also indicated that the Buffalo City Metro public libraries market library services by word of mouth, posters and notice boards. One of the major findings of the study is that Buffalo City Metro public libraries are faced with financial constraints and that led to a myriad of challenges ranging from inadequate library operating hours; limited information sources; lack of information retrieval training to patrons; internet connectivity issues; xii lack of professional staff and lack of training on the latest technological trends. The study concludes that the Buffalo City Metro public libraries should establish a marketing strategy to motivate for funding. The study recommended that the Buffalo City public libraries should create an integrated system for all libraries in the metromunicipality that encourages adult literacy programme to raise awareness of information literacy.

- Description: In South Africa at present, Literacy is a cause for rising concern, with reading and writing competency in primary school being at an all-time low. It is a widespread belief that part of the problem lies with the lack early childhood education. Only 37% of children under the age of five attend an early childhood development centre. Furthermore, South Africa has a shortage of educators, specifically within the domain of early childhood development. With more research being done in the area of literacy, more educators concur that emergent literacy forms the foundation of formal reading and writing later on. This study is a participatory case study, which reflects on the importance of literacy in the early years, showing the belief that pre-formal schooling, specifically emergent literacy, is directly linked to proficiency in reading and writing in formal schooling. This study also highlights how educators in early childhood development can be involved in ongoing reflective interventions through in-service training and communities of practice. This community of practice was developed as a series of focus groups, which met on a weekly basis to discuss and share thoughts, opinions and experiences surrounding emergent literacy in a preschool context. From multiple focus groups, I found that the participants became more confident in sharing their experiences and building upon each other’s ideas and thoughts. The focus groups, not only added to their understanding of emergent literacy, but enthused them and created more of an awareness in their day to day practices.

- Description: Non-disclosure of HIV/AIDS status is a topical issue in South Africa and across the globe. This study explored the ramifications of status non-disclosure by people living with HIV/AIDS (PLWHA) in Alice, Eastern Cape. The study aimed to explore the benefits and opportunities associated with HIV/AIDS disclosure; to examine the underlying factors discouraging Alice PLWHA from disclosing their status; to ascertain the ramifications of HIV/AIDS non-disclosure and to describe the coping strategies PLWHA and their families adopt in dealing with the ramifications of non-disclosure. The study employed the qualitative case study design, which was underpinned by the interpretive paradigm. The key informant’s method, in-depth interviews and focus group discussions were the main data collection methods. The sample of 35 participants was selected through the purposive and snowballing sampling technique. This sample comprised of 10 PLWHA, 20 family members and 5 key informants. The data collected from this sample was analysed through thematic content analysis. Findings indicated that PLWHA who disclosed their status accessed benefits and opportunities such as medication, psychosocial support, employment and the helping hands needed to manage their illness. In addition, the findings revealed that stigma, discrimination and socio-cultural factors inhibited some PLWHA from disclosing their status. Consequently, non-disclosure resulted in PLWHA experiencing ramifications such ramifications such as internal stigma, conflict in relationships, diminished career and educational achievement.

- Description: Youth substance abuse is a major social and health concern globally, South Africa notwithstanding. The effect of using substances among the youth does not only impend overall personal development of the youth, but it also limits their aspiration for the future and creates an environment that exacerbates to social ills. This study explored the effects of substance abuse among the youth in Dimbaza King Williams Town. The study intended to achieve the following specific objectives: (i) to establish the extent of the effects of substance abuse among the youth in Dimbaza township; (ii) determine the impact of the effects of substance abuse towards the development of Dimbaza Township; (iii) document interventional strategies to mitigate the effects of substance abuse. The study used a qualitative approach, where explorative and descriptive designs were used. Specifically, the case study design was used. Data was collected through in-depth interviews, focus groups, secondary data and key informants methods. The study used non-probability sampling techniques, but specifically purpose sampling technique was used. Twenty eight (28) participants were sampled which comprised of (12) youth faced with substance related challenges, (6) family members, and (10) key informants. Data was analyzed qualitatively through content thematic analysis. The study revealed the following: preponderance of marijuana (dagga) and alcohol, peer pressure as precursor to substance abuse, antisocial behaviours attributable to substance abuse, youth engagement in various criminal activities, evidence of moral decay in Dimbaza, state of poverty aggravating substance abuse habits, paucity of community intervention for social ills. The study made the following recommendations: a need for government to intensify awareness of the impact of substance abuse among the youth; the need for social practitioners to mitigate dysfunctional families facing substance related challenges; strategic educational intervention targeting potential addicts are needed so as to curb the proliferation the effect of substance abuse; establishment of family educational programs are needed to capacitate communities in order to mitigating substance related behaviors;; special police force is needed to strengthen substance abuse campaigns as primary intervention so as to educate pre-adolescents about the aftermaths of substance abuse; moral regeneration initiatives are needed to instill the significance of Ubuntu and worth of human being; intensify of moral regeneration campaigns facilitated by faith-based organizations; and lastly, the government and other stakeholders should fund youth development programs that will equip them with skills to afford them opportunities to bolster their lives and contribute to improving their country’s economy.

- Description: The dawn of democracy in South Africa led to the development of Language in Education Policy (LiEP) as one of the pieces of legislations that promote languages in schools where parents, learners, who have come of age may choose a language for instruction. LiEP, together with the Constitution of South Africa, promote equal value of all eleven official languages spoken in this country. The promotion of language policies clearly shows that language is the bedrock of the academic development of every child. Unfortunately, Spaull, Van der Berg, Wills, Gustafsson and Kotzè (2016) found that South African Foundation Phase learners lack the most basic skill needed for academic achievement, reading for meaning. Spaull et.al (2016) findings show that language problems start during the early years of schooling. This study aimed at finding out the perceptions of school stakeholders about the use of English as LoLT in Grade 9 Social Sciences, and it is located in the Interpretivist Paradigm. In this study, stakeholders are learners because they are central to learning, parents, as they have the responsibility of choosing LoLT for their children and assist them in their schooling career. Lastly, teachers are stakeholders because of their critical role of imparting knowledge and skills during classroom interaction. The researcher uses a Qualitative approach to identify data-collecting tools suitable for this research, and chooses semi-structured interviews and observations. Semi-structured interviews are flexible and allow deeper probing during the interview. The sample consists of nine Grade 9 learners, three teachers of Grade 9 Social Sciences and six parents from the School Governing Body (SGB). The aim of conducting observations was to find out the language used by learners and teachers during classroom interaction. This study found out that most participants prefer learning Social Sciences in English than in isiXhosa. They are aware of the challenges experienced in the classroom when learning in English but they still choose it. From the sample used, participants clearly indicate that learning in English causes some barriers in the learning and teaching process.

- Description: The dawn of democracy in South Africa led to the development of Language in Education Policy (LiEP) as one of the pieces of legislations that promote languages in schools where parents, learners, who have come of age may choose a language for instruction. LiEP, together with the Constitution of South Africa, promote equal value of all eleven official languages spoken in this country. The promotion of language policies clearly shows that language is the bedrock of the academic development of every child. Unfortunately, Spaull, Van der Berg, Wills, Gustafsson and Kotzè (2016) found that South African Foundation Phase learners lack the most basic skill needed for academic achievement, reading for meaning. Spaull et.al (2016) findings show that language problems start during the early years of schooling. This study aimed at finding out the perceptions of school stakeholders about the use of English as LoLT in Grade 9 Social Sciences, and it is located in the Interpretivist Paradigm. In this study, stakeholders are learners because they are central to learning, parents, as they have the responsibility of choosing LoLT for their children and assist them in their schooling career. Lastly, teachers are stakeholders because of their critical role of imparting knowledge and skills during classroom interaction. The researcher uses a Qualitative approach to identify data-collecting tools suitable for this research, and chooses semi-structured interviews and observations. Semi-structured interviews are flexible and allow deeper probing during the interview. The sample consists of nine Grade 9 learners, three teachers of Grade 9 Social Sciences and six parents from the School Governing Body (SGB). The aim of conducting observations was to find out the language used by learners and teachers during classroom interaction. This study found out that most participants prefer learning Social Sciences in English than in isiXhosa. They are aware of the challenges experienced in the classroom when learning in English but they still choose it. From the sample used, participants clearly indicate that learning in English causes some barriers in the learning and teaching process. However, it also became clear that the benefits associated with learning in English make it difficult to put it at the same level as other languages and participants do not link mother tongue to career opportunities. It is also evident that English will enjoy its hegemony until such time that all stakeholders in Education view the mother tongue as a foundation for learning other languages and as a resource as well so that they can use it in the classroom to understand the content. Policy developers must look deeply into the question of LoLT so that learners receive instruction in a language that will assist them in improved academic performance.

- Description: Maize (Zea mays L.) is a direct staple food crop in Africa and remains an essential component of global food security, with maize crops accounting for over 60% of the total harvested area of annual food crops. Stress caused by drought and high soil salinity limits crop growth and productivity more than any other single environmental factor, with grain yield reductions up to 76% depending on the severity of the drought and the plant growth stage. Arbuscular mycorrhizal (AM) fungi and Plant Growth Promotion Rhizobacteria (PGPR) have previously been shown to improve tolerance of plants to drought stress through a number of chemical and physiological processes. The aim of this investigation was to determine whether mycorrhizal fungi and rhizobacteria adapted to drought and saline conditions and possessing plant growth promoting (PGP) traits were able to stimulate plant growth responses when applied to Zea mays seeds growing under greenhouse conditions Bacterial isolates selected were tolerant to concentrations of NaCl up to 600 mM and maintained 50% growth at low water potentials (-1.44 MPa). They were positive for Indole Acetic Acid (IAA) production, phosphate solubilisation and secretion of siderophores. Bacterial isolates showing plant growth promoting potential were identified using 16S rDNA gene sequencing as Achromobacter xylosoxidans strains A8 and C54 and Klebsiella oxytoca strain M1. Mixed inoculum was prepared from indigenous communities of mycorrhizas in soils sampled from the Cerebos Salt Pan and the Kalahari Desert. Mycorrhizal diversity was investigated using 454-Pyrosequencing which revealed that the community composition was dominated by species in the Ambispora, Glomus and Paraglomus genera with a rare component represented by species in the Redeckera, Archaeospora and Geosiphon genera. Microscopic examination of plant roots at the end of the trial revealed the presence of diagnostic mycorrhizal structures within the root cells, confirming that colonization was successful. Plant growth response to microbial inoculation was assessed by monitoring changes in plant photosynthetic capacity over the duration of a 7 week pot trial. A significant difference in photosynthetic and biomass data was observed between drought and well-watered groups but no mycorrhizal or bacterial treatment effect was evident within the groups, despite the high levels of colonization by mycorrhizas. These results suggest that the beneficial effects of mycorrhizal colonization may be primarily attributed to improved nutrient and mineral uptake in conditions where nutrients are limiting, resulting in improved growth. The improved growth may then have secondary effects on the plant‟s ability to withstand drought. Having controlled for nutrient deficiency, it was not evident in this study that mycorrhizal fungi were able to stimulate a change in plant physiology and confer drought tolerance under the conditions imposed.

- Description: Effective learner participation for the development of Representative Council of Learners (RCL) governors in school governance (SG) is of great essence. A qualitative study was conducted in order to assess the learners’ views regarding their lived views and experiences in SG. Twenty four (24) RCL and class representatives from three data sites comprising three high schools in East Cape, in the East London District Education participated in the study. Data was gathered through semi-structured interviews, focus group discussions and document analysis from two convenient and one snowball samples, respectively. From each school, a chairperson, a secretary and six focus group discussions (FDGs) members were utilised as participants in order to enrich the study. In doing so, the study made use of Wilcox’s ladder of participation as the lens to unpack the learners’ views regarding their effective participation in school governance. This ladder includes information, consultation, deciding together, acting together and supporting independent community interests. The findings showed that learner participation in both township and former Model C schools is significant. However, a number of pertinent factors that make the voices of learner governors to be stifled emerged. These include lack of capacity building, exclusion from other meetings, dominance of adult governors, lack of collaboration and the fact that learners have to be seen as being respectful and disciplined when in meetings with parents. This makes them to accept their role as a tool for middlemen between the parents, teachers and fellow students. These make the field of effective learner participation uneven, hence making them window dressers and have pseudo contributions in SG. The study therefore suggested that learners should be capacitated to make effective and meaningful contribution in school governance. Learners should work collaboratively with adult governors to enhance effective participation in SG.

- Description: Stoichiometry is proven to be one of the difficult topics for learners in the NSSC Physical Science syllabus due to its abstract nature. Over the years the Examiner’s reports reveal that learners' performance is very poor in this topic. In addition, learners fear the topic and have developed a negative attitude toward it. It is against this background that I decided to carry out a qualitative case study; investigating how teachers mediate the learning of stoichiometry. The study was conducted at two schools in the Oshikoto Region, Namibia and it involved two grade 11 Physical Science teachers. The study is located within the interpretive paradigm and made use of interviews, document analysis and lesson observations (which were video-taped and transcribed) followed by stimulated recall interviews to generate data. The generated data were analyzed using the inductive approach whereby themes were identified. The themes were later used to develop analytical statements in relation to my research questions and these were used to interpret the data. Moreover, the study adopted the notion of pedagogical content knowledge (PCK) proposed by Shulman (1986, 1987) as well as Vygotsky's (1978) mediation of learning and social constructivism as the theoretical frameworks. The data were validated by triangulation, member checking as well as using the stimulated recall interviews while watching the videos with each participant. The findings of the study show that teachers use several tools to mediate the learning process and this includes the use of language, learners' prior knowledge and analogies. In addition, it emerged in this study that teachers are faced with a number of challenges when mediating learning of this topic. Hence, the study recommends that teachers should develop their pedagogical content knowledge for them to effectively eliminate the challenges faced as well as to come up with the best teaching strategies which they can use to mediate learning and help learners make sense of the topic stoichiometry.

- Description: This study explores the crisis of representation in black South African protest and ‘post’-apartheid literature. Conversant with the debates on the crisis of representation in black South African protest literature from the 1960s to the late 1980s, the dissertation proposes a re-reading of the ‘crisis’ by locating it in the black writer’s struggle for an aesthetic with which to express the existential crisis of blackness. I contend that not only protest but also contemporary or ‘post’-protest black South African literature exhibits a split or fractured mode of writing which is characterised by the displacement/unheimlichheid produced by colonialism and apartheid, as well as by the contentious nature of that which this literature endeavours to capture – the fraught identity of blackness. In my exploration of the split or double narratives of Mongane Serote’s To Every Birth Its Blood, K. Sello Duiker’s Thirteen Cents, and Kopano Matlwa’s Coconut, I examine the representation of blackness through the themes of violence, trauma, powerlessness, failure, and unhomeliness/unbelongingness – all of which suggest the lack of a solid foundation upon which to construct a stable black identity. This instability, I ultimately argue, suggests a move beyond an Afrocentric perspective on identity and traditional tropes of blackness towards a more processual, fluid, and permeable post-black politics.

- Description: This research focuses on the controversy surrounding the exhibition and media publication of Brett Murray’s painting, The Spear of the Nation (May 2012). It takes the form of a qualitative Critical Discourse Analysis (CDA), underpinned by Fairclough’s (1995) three-dimensional approach, to investigate how the contesting discourses articulated by the ruling political party (the ANC) and the news media have been negotiated in the City Press coverage in response to the painting. While the contestation was fought ostensibly on constitutional grounds, it arguably serves as an illustrative moment of the deeply ideological debate occurring in South Africa between the government and the national media industry regarding media diversity, transformation and democracy. It points to the lines of fracture in the broader political and social space. Informed by Foucault’s conceptualisation of discourse and the role of power in the production of knowledge and ‘truth’, this study aims to expose the discourses articulated and contested in order to make inferences about the various ‘truths’ the ANC and the media make of the democratic role of the press in a contemporary South Africa. The sample consists of five reports intended to represent the media’s responses and four articles that prominently articulate the ANC’s responses. The analysis, which draws on strategies from within critical linguists and media studies, is confined to these nine purposively sampled from the City Press online newspaper texts published between 13 May 2012 and 13 June 2012. Findings suggest the ANC legitimise expectations for the media to engage in a collaborative role in order to serve the ‘national interest’. Conversely, the media advocate for a monitorial press to justify serving the ‘public interest’. This research is envisioned to be valuable for both sets of stakeholders in developing richer understandings relevant to issues of any regulation to be debated. It forms part of a larger project on Media Policy and Democracy which seeks to contribute to media diversity and transformation, and to develop the quality of democracy in South Africa.

- Description: Most land is still state owned and is granted to users through traditional authorities. Even though the government has undertaken some programmes to reduce rural poverty and has initiated land reform programmes, improved service delivery and formed new water rights legislation in rural areas, the problem of low crop production still persists among South African farmers. The study was undertaken to identify different farmers’ aspirations and goals for expanding their crop production from homestead gardening to irrigation plots in Mhlontlo Local Municipality, in the Eastern Cape of South Africa. The central problem is that smallholder farmers are not expanding their scale of crop production even though they have access to natural capital which includes land and water. The broad objective of the study was to determine the aspirations and goals of farmers to expand irrigation crop production from homestead gardens to irrigation plots. The specific objectives of the study were to assess factors that addressed smallholder farmers’ aspirations and goals to expand crop production, to identify challenges that smallholder farmers encountered in expanding from homestead gardens to irrigation plots and to determine the current state of homestead gardens and irrigation plots. A list of 20 goals were identified from the field survey with 54 homestead food gardeners and 50 smallholder irrigation farmers in the different villages of the Mhlontlo Local Municipality. Random sampling was used to select the farmers who were asked to score the identified farm enterprise goals in terms of their relative importance. The goals were categorised into five factors using Gasson goal ranking methods which ranked goals on the basis of intrinsic, expressive, instrumental, and social criteria. The next step was to determine the standard deviations and means of the ranked goals. Descriptive statistics was then used to profile the farmers according to such factors as age, gender, years of farm experience, types of plot, the availability of water and land for crop production, the income farmers generate from the sale of crops produced and these are cross-tabulated with their goal rankings. The Logit model was used to estimate the probability that farmers would belong to a particular goal ranking and performance category. The logit model was also used to identify the factors that influence the expansion of the cropped area. The results revealed that maize production and land size where significant at 1%. Age and type of irrigation used were also positively significant at 1%. The results also revealed that the adoption of agricultural technology by smallholder irrigation farmers and homestead food gardens contributed to better quality produce.

Even though the government has undertaken some programmes to reduce rural poverty and has initiated land reform programmes, improved service delivery and formed new water rights legislation in rural areas, the problem of low crop production still persists among South African farmers. The study was undertaken to identify different farmers’ aspirations and goals for expanding their crop production from homestead gardening to irrigation plots in Mhlontlo Local Municipality, in the Eastern Cape of South Africa. The central problem is that smallholder farmers are not expanding their scale of crop production even though they have access to natural capital which includes land and water. The broad objective of the study was to determine the aspirations and goals of farmers to expand irrigation crop production from homestead gardens to irrigation plots. The specific objectives of the study were to assess factors that addressed smallholder farmers’ aspirations and goals to expand crop production, to identify challenges that smallholder farmers encountered in expanding from homestead gardens to irrigation plots and to determine the current state of homestead gardens and irrigation plots. A list of 20 goals were identified from the field survey with 54 homestead food gardeners and 50 smallholder irrigation farmers in the different villages of the Mhlontlo Local Municipality. Random sampling was used to select the farmers who were asked to score the identified farm enterprise goals in terms of their relative importance. The goals were categorised into five factors using Gasson goal ranking methods which ranked goals on the basis of intrinsic, expressive, instrumental, and social criteria. The next step was to determine the standard deviations and means of the ranked goals. Descriptive statistics was then used to profile the farmers according to such factors as age, gender, years of farm experience, types of plot, the availability of water and land for crop production, the income farmers generate from the sale of crops produced and these are cross-tabulated with their goal rankings. The Logit model was used to estimate the probability that farmers would belong to a particular goal ranking and performance category. The logit model was also used to identify the factors that influence the expansion of the cropped area. The results revealed that maize production and land size where significant at 1%. Age and type of irrigation used were also positively significant at 1%. The results also revealed that the adoption of agricultural technology by smallholder irrigation farmers and homestead food gardens contributed to better quality produce.

- Description: The catface rockcod Epinephelus andersoni is a range-restricted species that is endemic to the southeast coast of Africa from Quissico in Mozambique (subtropical) to Knysna in South Africa (warmtemperate). Its complex life-history, long-lived nature and high residency make E. andersoni potentially vulnerable to over-exploitation. Epinephelus andersoni is an important fishery species and has shown signs of depletion. Due to inadequate information necessary for management and conservation, further research is vital, particularly in the face of potentially significant climatic changes which could put further pressure on E. andersoni. The aim of the study was to provide information for the management of E. andersoni, with considerations for the possibly detrimental effects of future climate change. The objectives of this study were to describe the genetic structure and diversity of E. andersoni and to determine possible range shifts of E. andersoni with future changes in sea surface temperature. Genetic samples were collected throughout the distribution of E. andersoni. Standard DNA extraction and PCR using universal primers were conducted and nuclear (RPS7-1) and mitochondrial (cytochrome b) data were analysed to determine genetic diversity. A combination of nuclear and mitochondrial markers was used to ensure that the results were robust. RPS7-1 haplotype diversity was high (0.801) and an AMOVA on the RPS7-1 data showed significantly high among group variation (ΦCT = 0.204, p < 0.05) between five groups: 1. Quissico to Inhaca; 2. Cape Vidal to Port Edward; 3 Port St Johns to Coffee Bay; 4. Mbashe; 5. Port Alfred. This geographic structuring could be attributed to low gene flow across barriers such as the Port Alfred upwelling cell, the Mozambique Channel eddies and smaller more localised upwelling cells such as the Port St Johns cell. The cytochrome b results contrastingly indicate low haplotype diversity (0.309) and no differentiation (ΦCT = 0.265, p = 0.074) between groups and support the hypothesis of a historical population bottleneck. This may be due to an unusually slower mutation rate of the cytochrome b region than the RPS7-1 region, resulting in the RPS7-1 data showing a more recent picture of diversification. To complement the genetic results, niche modelling techniques were used to determine range shifts of E. andersoni with future temperature trends using species distribution and climatic data. The model illustrated a contraction of the E. andersoni distribution as well as future intensification of various upwelling cells along the south-east African coast including the Port Alfred upwelling cell. Due to the low gene flow across these barriers this intensification could decrease the resilience of E. andersoni, as its range becomes more limited with global change. The genetic data and modelling results combined provide useful information on which to base future fisheries management.

- Description: South Africa is the world's second largest exporter of fresh citrus and is ranked 14th in citrus production. Fungal pathogens such as Phytophthora and Pythium cause economic losses as a result of root rot and brown rot. Mycorrhizal fungi are specialized members of the fungal community forming a mutualistic relationship with plant roots. Mycorrhizal fungal structures are known to associate with other soil microorganisms and these may contribute to improved plant growth. A diverse group of bacteria that interact with the mycorrhizal fungi are known as Mycorrhizal Helper Bacteria (MHB). The aim of this study was to investigate the role of arbuscular mycorrhiza and associated bacteria isolated from spores and determine whether they had any plant growth promoting potential. A total of 19 bacteria were isolated from arbuscular mycorrhizal spores and were molecularly identified as belonging to several Bacillus, Micrococcus, Onchrobactrum and Staphylococcus sp. All bacterial isolates were tested for plant growth promotion abilities. One Bacillus isolate was able to solubilise phosphate. Four isolates Micrococcus sp, Micrococcus leteus, Ochrobacterum sp and Ochrobacterum antropi were able to produce Indole Acetic Acid and three isolates showed potential to reduce growth of Phytophthora nicotianae, P. citrocola and P. citrophthora in in vitro plate cultures. Further tests using culture supernatants of the Bacillus sp, Micrococcus sp and Bacillus cereus confirmed their ability to inhibit or reduce growth of the three Phytophthora species in a 96 well bioassay. Bacillus sp and Bacillus cereus were able to inhibit Phytophthora spp by 95 to 100 % and Micrococcus spp was able to decrease pathogen growth by 60 to 94 %. These bacterial isolates were further evaluated for plant growth promoting abilities on citrus rough lemon seedlings alone or in combination with arbuscular mycorrhizal inoculum. Bacterial and mycorrhizal inoculants influence the increase in shoot and root biomass. Bacillus cereus in combination with mycorrhizal inoculum significantly increased seedling shoot to root ratio while root biomass was significantly increased with mycorrhizal inoculation. Due to the short duration of the trial mycorrhizal colonisation could not be assessed. It is evident that selected combinations of bacteria and mycorrhizal fungi could promote citrus seedling growth and potentially improve seedling health. Further studies under nursery conditions are recommended.

- Description: The transformation process in the South African curriculum has highlighted a need for teachers to change from being passive implementers of curriculum. They are required to interpret the curriculum, adapt materials and develop lesson plans that will be responsive in their own context. They are also required to use materials and mediate learning. This research explores teacher acquisition of content knowledge on marine and coastal issues and probes how teachers work with materials in the development of lesson plans to contextualize the curriculum. A participatory action research process engaged 3 teachers in a contextualizing process of curriculum development. I started to work with the teachers to adapt and re-develop coastal and marine resources to support learning in local context. The research developed in two phases. The first examined existing teacher knowledge of marine and coastal issues and probed how content was integrated into lesson planning. Teachers identified knowledge acquisition as the priority to enable them to work with the materials and curriculum in their context. The second phase set out to enhance teachers’ knowledge of marine and coastal resources through workshops and field trips to improve the adaptation and use of materials. To document these processes and outcomes in the context of this study, I employed a range of data generation strategies including questionnaires, workshops and classroom observations, field notes, focus group discussion and the review of lesson plans, learners’ work and materials used. All participants collaboratively discussed and reflected on the process, but I was responsible for the final interpretation presented here. This study showed that teachers are still entrenched in their normal practice of working with content as facts and definitions, the delivery of abstract propositions that is not aligned with the curriculum goals. The new curriculum required teachers to change their teaching practice by using materials to mediate learning in context. The data revealed a mismatch between teacher practices and what the curriculum required from them.

- Description: This is an interpretive case study that explores the workplace epistemologies and institutional structures of two nested cases within the broader context of the Environmental Education, Training and Development Practices - Level 5 qualification (EETDP qualification) that is registered on the South African National Qualifications Framework. The study provides insights to inform EETDP curriculum development that is enabling of reflexive environmental education and training processes. The study develops an understanding of workplace epistemologies related to environment and education, the structural factors that enable and constrain agency of environmental educators and the role of reflexivity in practice and in education in two nested cases: the agricultural and local government sectors. It draws on findings from workshops, semistructured interviews and document analysis of education materials in these two nested cases. The study notes that there are diverse and seemingly ambiguous understandings of both environment/sustainability and education processes in the two nested cases. This ambiguity seems to relate to environmental education practitioners drawing on different forms of knowledge, including differentiated or theoretical knowledge, and 'common-sense' ways of knowing, in their education practice. The understandings related to theoretical knowledge are, in both nested cases, dominated by scientific or technical understandings where environment is understood in the terms of the natural sciences and education is seen in instrumentalist terms as the transfer of mainly technical environmental knowledge to learners in order to effect behaviour change. The study opens up deeper understandings of the epistemological, socio-cultural and structural features of context, in the two nested cases, that have a bearing on environmental educators. It provides insights into workplace structures that can be both enabling and constraining of agency and notes that the causal power of structures to enable or constrain does not lie only in the structures but also in relation to the intentionality of the environmental education practitioners/agents. The study then examines reflexivity as one of the means through which environmental educators in the nested cases are able to consider appropriate actions or responses to structural constraints or enablements. Based on the insights offered by the research findings, the study makes recommendations for the EETDP curriculum development. It frames these recommendations within an understanding of curriculum as a contextualised social process that involves structural aspects of curriculum such as materials, as well as socio-cultural processes such as learning on the course and in the workplace.

- Description: The research reported here investigated the use of a Baffle Reactor in order to study aspects of the biological sulfur cycle, where a floating sulfur biofilm formation occurs and where complex organic compounds provide electron donor sources. The development of a laboratory-scale Baffle Reactor model system satisfied the requirements for sulfate reducing bacterial biomass growth and sulfur biofilm formation. Since relatively little is known about the microbial ecology of floating sulfur biofilm systems, this study was undertaken to describe the sulfate reducing sludge population of the system together with its performance. A combination of culture- and molecular-based techniques were applied in this study in order to investigate the microbial ecology of the sulfate-reducing bacteria component of the system. These techniques enabled the identification and the analysis of the distribution of different sulfate reducing bacterial strains found within the sludge bioreactors. Strains isolated from the sludge were characterised based on culture appearance, gram staining and scanning electron microscopy morphology. Molecular methods based on the PCR-amplified 16S rRNA including denaturing gradient gel electrophoresis were employed in order to characterise sulfate-reducing bacteria within the reactors. Three novel Gram negative sulfate-reducing bacteria strains were isolated from the sludge population. Strains isolated were tentatively named Desulfomonas rhodensis, Desulfomonas makanaiensis, and Clostridium sulforhodensis. Results obtained from the Baffle Reactor showed that three dominant species were isolated from the DNA extracted from the whole bacterial population by peR. Three of these were similar to those mentioned above. The presence of these three novel unidentified species suggest that there are a range of other novel organisms involved in sulfate reduction processes.

- Description: This study aimed at focusing on the challenges facing probation officers working with young persons in conflict with the law, in the Eastern region, which forms part of the Eastern Cape Province. The main purpose of the study was to explore the experiences of probation officers in terms of the legislation that they are using when making decisions pertaining to young persons and the types of programmes that they offer to young persons for diversion and prevention purposes. The researcher also wanted to generate a greater understanding of the resources which probation officers have and need in order to run their programmes successfully to young persons, as well as to explore their feelings about working with young persons. The researcher did some literature review in relation to this field, where it became evident that probation services in respect of young persons in conflict with the law, is a relatively new field of specialisation in South Africa. This field started around 1995 as a result of the Inter - Ministerial Committee (IMC) on young people at risk, which was set up to respond and manage the crisis of more than one thousand children who were released from prisons and police cells. The IMC then, identified probation officers as leading role players in dealing with young persons in conflict with the law. An exploratory (non - experimental) design was used to carry out the research. A qualitative research method was also used as it attempts to describe and explain social reality from the points of view of the participants. This is because the researcher was interested to find out the experiences of probation officers in relation to their work with young persons. A non - probability purposive sample of all (11) probation officers was used. A semi - structured interview schedule with both closed and open - ended questions was used to collect data. All the information gathered from those personal interviews, was analysed by hand because the researcher wanted to interpret and produce social explanations. The findings of this small - scale study have revealed that there are a number of challenges facing probation officers. For example presently there is no comprehensive legislation for the management of young persons caught up in the criminal justice system. Instead, limited provisions are spread throughout a number of separate statutes, which make it difficult for probation officers to apply them. This study has also revealed that there is a shortage of human and material resources, which somehow impact negatively on how probation officers render services to their clientele. All probation officers in this study have positive feelings and attitudes about their work despite the fact that there are some challenges facing them that need to be addressed. Specific recommendations have been made based on the findings of this study, which could contribute to the development of probation services in respect of young persons in conf lict with the law
