- Description: School-based sexuality education has been the subject of research in the social sciences and pedagogical spheres globally. In South Africa, growing interest among social scientists in the topic, were ignited by the introduction of sexuality education as a compulsory part of Life Orientation (LO) by the late 1990s. However, the implementation of LO has been problematic. Reviewed literature in the current study, reveals how the dominance of the heterosex discourse is foregrounded in LO content on gender and sexuality. The current study was aimed at examining the construction of gendered relationships in LO textbooks. The study sampled LO textbooks for Grades 10-12, learners in these grades are between the mean ages 16-18 years. This group is the target group, because they are legally afforded the right to consent to sexual activity with peers, within the same age bracket. Conducted from a social constructionist perspective, the current study employed qualitative methods of inquiry (textual analysis). Against the backdrop of heterosexuality as norm, it was the aim of the current study to understand the subject positions made available for female learners to construct themselves, within the discursive spaces in LO content. Findings suggest that two discourses namely: the heterosex discourse and the discourse of danger and disease, dominate in LO content on gender and sexuality. This leads to the construction of gendered relationships a s inherently heterosexual, leading to the marginalisation of relationships that fall outside of the norm. The female learner is positioned as a passive-victim, incapable of exercising sexual agency, while young men are positioned as inherently more powerful members of the intimate relationships or dangerous sexual predators. In the discourse of danger and disease, she is also positioned as a potential victim but the focus is on equipping her with skills, in a way which positioned her as an active-resistor in refusing sexual activity; and being in control of decision-making on issues of safety in relationships. The implications of these contradictions, is that they focus on the individual and disallow her taking up of sexual agency, and disregard the context in which she has to do so.

- Description: Plasmodium falciparum is a protozoan parasite that causes a severe form of malaria, a mosquito-borne infectious disease in humans. P. falciparum encodes a number of proteins to facilitate its life-cycle, including a type II heat shock protein 40 (Hsp40), Pfj2. Pfj2 shows a degree of homology to human ERdj5, a resident protein of the endoplasmic reticulum (ER) that promotes protein quality control by facilitating the degradation of misfolded proteins. The overall aim of this study was to further understand the function of Pfj2 in the P. falciparum cell by characterising it biochemically. A bioinformatic analysis of Pfj2 was carried out to enable the identification of a potential ER signal sequence and cleavage site. Furthermore, an analysis of Pfj2 protein sequence was performed to compare domain similarities and identities with typical type II Hsp40s namely, human ERdj5, S. cerevisiae Sis1, human Hsj1a and human DnaJB4. The method used included the insertion of the codon-optimised coding sequence for the processed ER form of Pfj2 into the prokaryotic expression vector, pQE30, to enable overproduction of a histidine-tagged protein. A 62 kDa His₆-Pfj2 was successfully expressed in Escherichia coli and purified using denaturing nickel affinity chromatography. ATPase assays were performed to determine the ability of His₆- Pfj2 to stimulate the chaperone activity of the ER Hsp70, also called immunoglobulin binding protein (BiP). Initial studies were conducted on readily available mammalian His₆-BiP as a control, which was shown to have an intrinsic activity of 12.07±3.92 nmolPi/min/mg. His₆- Pfj2 did not stimulate the ATPase activity of mammalian His₆-BiP, suggesting that it either could not act as a co-chaperone of mammalian His₆-BiP (specificity), or it required a misfolded substrate in the system. Therefore, ongoing studies are addressing the interaction of Pfj2 and misfolded substrates with P. falciparum BiP. The results of these studies will further our understanding of a poorly-studied parasite chaperone that represents a potential drug target for development of novel strategies for the control of a serious human disease

- Description: South African education is in the process of undergoing what has become known as a "paradigm shift", requiring a change from the familiar transmission method to outcomes-based education (OBE) founded on social constructivist theories oflearning and teaching. Teachers, (45% of whom are poorly qualified), "will play a pivotal role in the success or failure of this change. There is therefore an urgent need to re-educate in-service teachers in the philosophy, and related methodologies underpinning Curriculum 2005. To this end, in-service education courses need to be developed "which will encourage teachers to reconstruct their beliefs about teaching and learning. INSET programmes in the past were aimed at either "topping up" qualified teachers, or "adding on" for under qualified teachers - neither of which have proved successful. It is therefore unlikely that applying similar methodologies to support teachers in the shift to OBE will meet with success, nor will simply "training" teachers to use the new learning programmes. Government documents on Education Policy are calling for teachers to become reflexive practitioners, able to guide learners in their efforts to achieve the critical outcomes which are intended to develop a competent citizenry of lifelong learners. Therefore, teachers ought to be empowered as curriculum developers in their own right. This interpretative case study hoped to find out from teachers themselves what aspects of an activity-based environmental education course acted as change agents in assisting them to begin the shift to constructivist theories of teaching and learning. A variety of research tools were used, including questionnaires, interviews, journals, narratives and concept maps, all of which provided a rich source of data for interpretation. From what was gained from four participants in this research, tentative suggestions for incorporation into the next cycle of action research in future INSET programmes are made.

- Description: Monetary policy announcements are among the major decisions that affect the economy as a whole. The purpose of this study was to analyze the impact of monetary policy announcements on equity markets in South Africa during 2014-2015 financial years. That financial period is a unique year for analyzing the impact of monetary announcements on stock returns because the Reserve Bank Governor was changed in the last quarter of 2014. Moreover, interest rates were changed in four monetary policy announcements over the course of two years. This provides a good opportunity to investigate how monetary policy announcements can affect financial markets. The study used an event study methodology whereby a 15-day event window is used as well as a 45-day estimation window. Around the event window, abnormal returns were calculated using the market model and capital asset pricing model (CAPM) was used to calculate expected returns. The results are mixed; (both significant and insignificant) impact of monetary policy announcements on JSE stock returns. Of the 12 interest rates announcements, only four seemed to be significant. It was observed that of the four significant results, three of them were because of a hike in interest rates. The results show an asymmetric response by the market to interest rate changes. The results also suggest that the market anticipated the relative volatility arising from the change of the minister of the reserve bank governor. Following the appointment of the new Central Bank‟s governor in the last quarter of 2014, the first interest rate announcement seemed to have been anticipated by the public thereby rendering it insignificant. Inorder to improve the strength of the results in future, it is important that that there should be the absence of signalling effect in the market. It is recommended that the markets are efficient and the announcements should not be highly anticipated by the public.

- Description: The thesis aims to show that, while an interpretive psychology is not compatible with theory as it occurs in the predictive- causal explanation of the natural sciences, it is both possible and necessary to develop a concept of theory valid within an interpretive methodology. These claims are advanced in the course of an examination of Ricoeur 's interpretation of Freudian psychoanalysis. After examining some traditional ways in which phenomenological psychology has responded to the psychoanalytic challenge, the thesis presents an interpretation of Freudian psychoanalysis as a hermeneutic approach which utilized theoretical constructions in a productive way, although distorted by Freud's natural-scientific self- understanding. Freud's causal-explanatory language and natural- scientific meta theory are shown to be significant inasmuch as they provide a vehicle for theory construction in psychoanalysis. However, since the theory is modeled on that of the natural sciences, it proves incompatible with the interpretive aspects of Freud's approach. We then establish a concept of theory and of causal analysis which is different to that of the natural sciences, and is compatible with, and indeed founded in, an interpretive approach to psychology. These concepts are then illustrated in the context of psychoanalysis. In the final chapter the advantages of the use of theory in interpretive psychology are discussed.

- Description: This research explores the potential for engaging teachers in school-based environmental education curriculum development processes by using camera. The research, through its epistemological and ontological position, is closely linked to educational orientations associated with aspects of outcomes-based educational transformation in South Africa. A participatory approach that recognises teachers as co-researchers, each bringing to the inquiry her or his questions and constructions of meaning, was adopted. Participatory inquiry was initiated by setting up cluster meetings that allowed for teacher inputs through open dialogic processes. Fundamental to the inquiry is the notion that context shapes curriculum and curriculum development processes. It was from this orientation that a group of 13 teachers, using cameras to create visual narratives, explored their own diverse and complex contexts. These narratives (or stories) form the basis for further inquiry and development of sophistication with respect to the concept of environment. The research process is critically and reflexively documented as a series of field and research texts constructed from a variety of data sources gathered over the period of one year. The work is presented as a process of engaging critically with environmental education curriculum development and an opportunity to raise questions, rather than seek answers in this regard.

- Description: This case study reports on a patient who was undergoing psychotherapy for an Adjustment Disorder with Mixed Emotional Features. The aim of the study had two aspects. First the study sought to establish to what degree was enmeshment between the patient and his mother responsible for his maladaptive behaviour. The second aspect was to establish the extent to which the patient responded to psychotherapy. The patient was a 20 year old male university student. He was experiencing a number of problems including difficulty in interpersonal relations, deteriorating academic performance, depression, anxiety and uncertainty about career choice and about the future. The history revealed that the patient had very close and enmeshed relations with his mother. The mother was a very domineering person and had great influence on her son. On the other hand his father was weak and emotionally unavailable. The patient had never been away from home until after he graduated from High School and decided to join the army. It was then his problem began to manifest. He left the army and registered at university. However, the problems continued and even increased in intensity. It was hypothesized that as a result of enmeshment with his mother and the fact that his mother was a domineering personality, he never had the opportunity to learn social skills that would have enabled him to emancipate himself from his mother . Thus when he moved out of home to be on his own, first in the army and later at university, he could not cope. He lost self-confidence, became passive, indecisive and dependent. Psychotherapy was successful in helping him gain insight into the genesis of his problem. This insight resulted in the patient's efforts towards individuation.

- Description: This dissertation is concerned with loss and abandonment, and together with the practical component, titled Restitution, forms part of a Master of Fine Art degree submission. Both loss and abandonment can take many forms, from the straightforward deterioration, departure or removal of objects to the more complex deterioration of memory, responsibility and dignity. It seems though, that the question, “What has been lost?” is one that is always asked once it is too late. The loss becomes irretrievable and one is left only with fragments and traces. In Chapter 1 issues of liminality and the precariousness of being between states is addressed. Dignity of the ‘other’, in this case the deceased pauper, is interrogated especially with reference to complicity, forensic investigation and the forensic aesthetic. Chapter 2 outlines photographic representation, with attention given to posthumous portraiture, the punctum and memory in the service of permanence and authenticity. Chapter 3 considers the ambition and purpose of the artist through a critique centred on contemporary photographic artist, Sally Mann. Throughout the thesis and exhibition, I am concerned with loss as it relates physically to objects. Metaphorically, I investigate loss and abandonment in relation to dignity and responsibility. In so doing I view death as being the ultimate form of loss, as there is physical loss of the body, as one part of the whole that makes up ‘the person’, as well as the psychological and emotional loss that attends the passing of life. The delayed burial of the deceased therefore is seen to be evidence of abandonment at its extreme. I end by positioning my conclusion around a stop animation series in which I dug a grave and buried a pauper at Mayfield cemetery.

Chapter 2 outlines photographic representation, with attention given to posthumous portraiture, the punctum and memory in the service of permanence and authenticity. Chapter 3 considers the ambition and purpose of the artist through a critique centred on contemporary photographic artist, Sally Mann. Throughout the thesis and exhibition, I am concerned with loss as it relates physically to objects. Metaphorically, I investigate loss and abandonment in relation to dignity and responsibility. In so doing I view death as being the ultimate form of loss, as there is physical loss of the body, as one part of the whole that makes up ‘the person’, as well as the psychological and emotional loss that attends the passing of life. The delayed burial of the deceased therefore is seen to be evidence of abandonment at its extreme. I end by positioning my conclusion around a stop animation series in which I dug a grave and buried a pauper at Mayfield cemetery.

- Description: The chemical composition of the mandibular gland extracts of Apis mellifera capensis virgin queens was analysed by gas chromatography-mass spectroscopy. Thirty-seven compounds from various chemical groups including aliphatic and aromatic acids and diacids, phenols, alkanes, amino acids and sugars were identified. Among the identified compounds were the queen mandibular pheromone components 9ODA, 9HDA, HVA and HOB and the other aliphatic acids and phenols considered to be the major components of A.m. capensis mandibular glands. Ontogenetic changes in the concentration of the mandibular gland secretions of virgin queens were largely quantitative in nature with the total volume and that of most of the compounds increasing with queen age. The final level of 9ODA is reached at the premating stage, approximately three days after emergence, when it comprises approximately 87% of the major constituents of the mandibular gland signal. Hostile reactions by workers towards introduced virgin queens can be correlated to the relative proportion of 9ODA present in the mandibular gland secretions. This seems to indicate that it is the complete spectrum of the signal and not individual compounds that determine worker reaction towards introduced queens. Keeping queens singly, with or without workers, in an incubator and in small mating nucleus hives proved to be the most successful methods of queen rearing in respect to survival rate in A.m. capensis. The presence of workers during the ageing of virgin queens was found to significantly affect the chemical composition of the mandibular gland secretions of queens. The reaction of workers towards introduced virgin queens reared under different holding conditions varied, with queens reared with workers eliciting significantly less hostile reactions from workers than those reared without workers. Mated queens from five localities in the Eastern Cape were characterised on the basis of the chemical composition of their mandibular gland secretions and the ratio of 9ODA:10HDA. No significant differences were detected and none of the queens sampled could be considered to be A.m. capensis based on their mandibular gland signal. The findings of this study provide baseline data for the development of a queen-rearing program tailored to the specific requirements of A.m. capensis.

- Description: Orientation: Technology affects organisations both positively and negatively and in some instances technology factors can result in turnover intentions for certain employees of organisations. Research purpose: The main objective of the study was to investigate how technology-based job autonomy, technology-based job overload and technologybased job monitoring impact turnover intentions of employees. Motivation of the study: Exploring and understanding the relationship between technology factors and turnover intention amongst government employees to determine whether these factors affect government as much as they affect the private sector. Research design, approach and method: This research used a quantitative research approach. It drew a convenience sample of 182 employees (N= 182) from the South African Government. Main findings: The three main findings of the study were: Technology-based job autonomy was positively related to turnover intention. Technology-based job overload was found to be positively related to turnover intention. Finally, technology-based monitoring was found to be positively related to turnover intention. Practical/managerial implications: If organisations do not address the issue of monitoring and overload they are likely to experience many turnover intentions amongst the employees. Furthermore, the organisations with less autonomy are likely to lose their employees which means they will lose the resources that have been serving the organisation for a long time. This will also contribute to the organisation losing many funds as they would constantly have to train new employees. Contribution/value-add: The research adds value to the knowledge about the effects of technology factors on turnover intention by pointing out the reasons that lead to turnover intention.

- Description: Given the importance of monetary policy in the operation of a successful modern economy and the use of official interest rates as tools in its implementation, this study investigates the implications of changing bank concentration on the operation of the Interest Rate Pass Through (IRPT) of official rates to bank lending and deposit rates. This is an issue made more poignant by growing mergers, acquisitions and bank consolidation exercises around the world that have brought interest to their implications for economic performance. However, with contention high in the industrial organisation theory on the likely relationship between bank concentration and the IRPT, and the outcomes of empirical investigations producing conflicting evidence, the desire to investigate the issue in the African context necessitated a thorough empirical investigation of four African countries (South Africa, Botswana, Nigeria and Zambia). This study not only extended the investigation of the issue to the African context, but it merged different IRPT measurement techniques that had not been jointly applied to this particular issue, namely; Symmetric and Asymmetric Error Correction Models, Mean Adjustment Lags, Ordinary Least Squares estimations and Autoregressive Distributed Lag models. These measures of the IRPT were compared with three firm concentration ratios on two different levels of analysis, one, over the entire period and, another, through eight year rolling windows. The results reveal that bank concentration can sometimes be related to the speed and magnitude of the IRPT but that these relationships are not consistent amongst the countries, over the entire sample period or across the two levels of analysis, suggesting reasons why empirical results have arrived at contrasting conclusions. The results revealed more evidence of a relationship between bank concentration and the magnitude of the IRPT than between bank concentration and the speed of the IRPT. Furthermore, where relationships were identified there was evidence supporting both the structure conduct performance hypothesis and the competing efficient market hypothesis as the true representation of the relationship between bank concentration and the IRPT. The key implication of the result for African countries is that increased bank concentration through bank consolidation programmes should not be automatically regarded as detrimental to the effective implementation of monetary policy through the IRPT. Consequently,banking sector regulation need not stifle bank consolidation and growth to preserve monetary policy effectiveness. Rather, since the relationship cannot be neatly represented by a single theory or hypothesis each country must determine its own interaction between bank concentration and its IRPT before policies regarding the banking sector concentration and effective monetary policy, through the use of official interest rates, are determined.

- Description: The demersal fishery off the west coast of South Africa experiences decreased catches per unit effort of hake, Merluccius capensis and M. paradoxus, following the onset of strong south easterly winds. Research has demonstrated that, during daylight hours, Cape hakes migrate vertically in the water column in response to strong south easterly winds, decreasing their availability to the bottom trawl. Hydroacoustic, trawl and environmental data were collected off the West Coast during both calm and wind-swept periods in an attempt to understand the forces that initiate this behaviour, its spatial variability and the implications for demersal trawl estimates of abundance. Near-bottom currents appear to be the primary factor influencing the vertical distribution of the demersal fish community, of which hake constitutes a large proportion, during daylight hours. Correlation between wind and near-bottom currents suggest that the poleward component of the currents increase in velocity within eight hours following the onset of south easterly winds. The fish avoid boundary layers where currents change direction and speed dramatically, and seem to concentrate in waters with relatively stable current regimes. This result questions the assumption of CPUE-based assessment models that hake availability to the bottom trawl is constant or varies randomly. The incorporation of acoustic assessment techniques to demersal surveys has potential, but may be most valuable by supplementing swept-area estimates of abundance, since the sampling efficiency of these methods varies within the water column. The incorporation of wind indices and gear performance data to Cape hake assessment models have been identified as useful considerations for the future.

- Description: The study was conducted in two communal abandoned grazing lands, namely; Sinqumeni and Kubedlana (referred hereafter as sites) located in the Eastern Cape Province (ECP) where legume pastures have been successfully established for the last ten years. The objectives of the study were to investigate the effects of five different herbicide treatments and four different phosphorus fertilizer application rates on forage production and plant density of abandoned lands. At each site, an area previously planted with legume species and well established with an even stand of legumes were selected. For both experimental sites, experimental design consisted of plot size of 50 m × 50 m for herbicide plot and 25 m ×25 m for phosphorus plot with 5 m×10 m of sub-plot planted with an even stand of pasture legumes arranged in a randomised complete block design (RCBD) in two blocks. The legumes that were planted in these sites were: Lotus corniculatus, White clover, Arrow leaf clover, Yellow serradella, Pitman serradella, Biserrula and Lespedeza cuneata. Prior to planting, the legume seeds were mixed with the appropriate inoculant by hand. Planting was done by over sowing legumes into the natural pastures (grasses) using an Aitchison Mini seeder. In each small plot, data was collected on forage biomass and plant density (species count). Data was analysed using the SAS programme and the significance of differences between means were tested with Fisher’s test for the LSD. On herbicide study, results showed that there were no significant (p > 0.05) difference in forage dry matter (DM) among the herbicide treatments in both years at Kubedlana. Results further showed that all five herbicides did not significantly (p > 0.05) increase the DM yield over control treatment. At Sinqumeni, results displayed no significant (p > 0.05) difference in forage DM among treatments during year 1, whereas in year 2, but all herbicide treatments except Haloxyfop-R methyl & Bendioxide (HBE) yielded greater (p < 0.05) DM yield than the control treatment. Comparing years, forage DM yield only under Bendioxide (BEN) and Paraquat (PAR) treatments had greater DM yield in year 2 than years 1. In Kubedlana, Bendioxide (BEN) and Haloxyfop-R methyl (HAL) treatments showed an IV increase in total density (TD), whereas Glyphosate (GLY) produced the lowest total density (TD) and Paraquat (PAR) and Haloxyfop-R methyl (HAL) resulted in an increased in density of total legumes (TL) relative to control treatment. There was a decline (p < 0.05) in the densities of total plants and forbs from year 1 to year 2. In Sinqumeni, herbicide applications resulted in higher density of total legumes than the control treatment, but results varied among herbicide treatments, greatest density being obtained at Haloxyfop-R methyl & Bendioxide (HBE) and Haloxyfop-R methyl (HAL) treatments. On phosphorus study, result showed a significant (p < 0.05) differences in dry matter (DM) yield among Phosphorus (P) treatments during year 2 of the study at Kubedlana site. All P treatments showed significantly greater dry matter (DM) yield in forage harvested in year 2 compared to year 1. At Sinqumeni, results showed Phosphorus (P) application did not have significance (p > 0.05) effect on forage dry matter (DM) yield on both years. In Kubedlana, there were indications of increased densities of total grasses, legumes and total plants in response to some levels of phosphorus (P) treatments. Treatment Phosphorus at 20 kg ha-1 (P20) yielded the highest total density (TD) and total legumes (TL) numbers and P10 had the lowest total density (TD). Both treatment and year interacted significantly (p < 0.05) to influence the mean density of some plant variables. At Sinqumeni, there were no significant differences due to phosphorus (P) treatments in the densities of total plants, grasses and forbs. Both years interacted significantly (p < 0.05) with treatments to influence the plant density mean, with Lespedeza cuneate (LESP) producing the highest plant density during year 1 and year 2, whereas BSERRL produced the lowest plant density during year 1 and year 2 periods. Therefore, findings of this study suggest that application of both Bendioxide (BEN) & Haloxyfop-R methyl & Bendioxide (HBE) treatments result in a decrease in dry matter (DM) yield, whereas Glyphosate (GLY) herbicide resulted in a decrease in both total density (TD) and total legumes (TL) and Haloxyfop-R methyl (HAL) herbicide application resulted in an increase of total density (TD) and total legumes (TL) V relative to control plot. On phosphorus study, results suggest that at Phosphorus at 40 kg ha-1 (P40) fertilization dry matter (DM) yield will be increased and at both Phosphorus at 20 kg ha1 (P20) and Phosphorus at 40 kg ha-1 (P40) high total density (TD) will be recorded where’s Phosphorus at 20 kg ha-1 (P20) fertilization result in high total legumes (TL).

- Description: The study was conducted in two communal abandoned grazing lands, namely; Sinqumeni and Kubedlana (referred hereafter as sites) located in the Eastern Cape Province (ECP) where legume pastures have been successfully established for the last ten years. The objectives of the study were to investigate the effects of five different herbicide treatments and four different phosphorus fertilizer application rates on forage production and plant density of abandoned lands. At each site, an area previously planted with legume species and well established with an even stand of legumes were selected. For both experimental sites, experimental design consisted of plot size of 50 m × 50 m for herbicide plot and 25 m ×25 m for phosphorus plot with 5 m×10 m of sub-plot planted with an even stand of pasture legumes arranged in a randomised complete block design (RCBD) in two blocks. The legumes that were planted in these sites were: Lotus corniculatus, White clover, Arrow leaf clover, Yellow serradella, Pitman serradella, Biserrula and Lespedeza cuneata. Prior to planting, the legume seeds were mixed with the appropriate inoculant by hand. Planting was done by over sowing legumes into the natural pastures (grasses) using an Aitchison Mini seeder. In each small plot, data was collected on forage biomass and plant density (species count). Data was analysed using the SAS programme and the significance of differences between means were tested with Fisher’s test for the LSD. On herbicide study, results showed that there were no significant (p > 0.05) difference in forage dry matter (DM) among the herbicide treatments in both years at Kubedlana. Results further showed that all five herbicides did not significantly (p > 0.05) increase the DM yield over control treatment. At Sinqumeni, results displayed no significant (p > 0.05) difference in forage DM among treatments during year 1, whereas in year 2, but all herbicide treatments except Haloxyfop-R methyl & Bendioxide (HBE) yielded greater (p < 0.05) DM yield than the control treatment. Comparing years, forage DM yield only under Bendioxide (BEN) and Paraquat (PAR) treatments had greater DM yield in year 2 than years 1. In Kubedlana, Bendioxide (BEN) and Haloxyfop-R methyl (HAL) treatments showed an IV increase in total density (TD), whereas Glyphosate (GLY) produced the lowest total density (TD) and Paraquat (PAR) and Haloxyfop-R methyl (HAL) resulted in an increased in density of total legumes (TL) relative to control treatment. There was a decline (p < 0.05) in the densities of total plants and forbs from year 1 to year 2. In Sinqumeni, herbicide applications resulted in higher density of total legumes than the control treatment, but results varied among herbicide treatments, greatest density being obtained at Haloxyfop-R methyl & Bendioxide (HBE) and Haloxyfop-R methyl (HAL) treatments. On phosphorus study, result showed a significant (p < 0.05) differences in dry matter (DM) yield among Phosphorus (P) treatments during year 2 of the study at Kubedlana site. All P treatments showed significantly greater dry matter (DM) yield in forage harvested in year 2 compared to year 1. At Sinqumeni, results showed Phosphorus (P) application did not have significance (p > 0.05) effect on forage dry matter (DM) yield on both years. In Kubedlana, there were indications of increased densities of total grasses, legumes and total plants in response to some levels of phosphorus (P) treatments. Treatment Phosphorus at 20 kg ha-1 (P20) yielded the highest total density (TD) and total legumes (TL) numbers and P10 had the lowest total density (TD). Both treatment and year interacted significantly (p < 0.05) to influence the mean density of some plant variables. At Sinqumeni, there were no significant differences due to phosphorus (P) treatments in the densities of total plants, grasses and forbs. Both years interacted significantly (p < 0.05) with treatments to influence the plant density mean, with Lespedeza cuneate (LESP) producing the highest plant density during year 1 and year 2, whereas BSERRL produced the lowest plant density during year 1 and year 2 periods. Therefore, findings of this study suggest that application of both Bendioxide (BEN) & Haloxyfop-R methyl & Bendioxide (HBE) treatments result in a decrease in dry matter (DM) yield, whereas Glyphosate (GLY) herbicide resulted in a decrease in both total density (TD) and total legumes (TL) and Haloxyfop-R methyl (HAL) herbicide application resulted in an increase of total density (TD) and total legumes (TL) V relative to control plot. On phosphorus study, results suggest that at Phosphorus at 40 kg ha-1 (P40) fertilization dry matter (DM) yield will be increased and at both Phosphorus at 20 kg ha1 (P20) and Phosphorus at 40 kg ha-1 (P40) high total density (TD) will be recorded where’s Phosphorus at 20 kg ha-1 (P20) fertilization result in high total legumes (TL).

- Description: This thesis attempts to examine the construction of 'professionalism' within the newsroom of the Cape Argus, an English-medium newspaper in post-apartheid South Africa. It is a qualitative study which tries to evaluate how a particular mainstream media discourse of 'professionalism' is enacted and struggled over in the attitudes, behaviour and perceptions of entry-level journalists and news managers at the newspaper. It asks what the process of 'becoming a journalist' requires of entry-level journalists in terms of their previous education and personal qualities - and examines the newsroom strategies employed by news managers when entry-level journalists do not meet these particular requirements. This thesis looks at how the pressures of operating a daily English-language commercial newspaper may shape both the 'professional' expectations of news managers and their ability to positively contribute to entry-level journalists' 'newsroom training'. In attempting to examine the nature of journalistic 'professionalism', this study explores the ideology of knowledge construction within mainstream South African media. Operating from a 'radical democratic' perspective of journalism, which prioritises journalism as a vehicle for diverse social, cultural and political expression, this thesis suggests that South African media education needs to enable journalism students' understanding of the ideological construction of journalistic 'professionalism'.

- Description: The media, which help define what we think and our roles in the society, have a crucial role to project both men and women’s issues so as to change people’s perceptions and stereotypes about the role men and women play in the society. There is need, therefore, to ensure gender equality in the operations of the media so that issues to do with both men and women get adequate and equal coverage. This study on the reportage of the land redistribution exercise in Zimbabwe has, however, exposed the gendered nature of the operations of the media, particularly in the news production process. It provides that, overally, the news discourse is a masculine narrative whose androcentric form is a result of, and is protected by, claims to ‘objectivity,’ ‘professionalism’, ‘impartiality’ and the pursuit of a journalistic routine system that hegemonically prioritises men’s issues over those of women. The situation, as the research shows, has not been helped by journalists’ incapacity to do thematic appreciation of issues and their over-inclination towards a simplistic event-based journalism that fails to question policies as they are enacted and implemented in gender-skewed processes. The lack of gender policies, the operations of patriarchy and the pursuit of a journalistic routine system that sees nothing wrong with the ostracisation of women issues are very fundamental findings that the research uses in its attempts to explain why the gender equality discourse was left out of the news reports about the land reform exercise in Zimbabwe.

- Description: Previously understood as a fixed and universal set of behaviours social constructionists are now arguing that masculinity is contextual and fluid, reflecting a multiplicity of different understandings. Within any 'cultural environment' the discourse of masculinity, culturally and historically bound, expresses attitudes and behaviours that shape the understanding of what it means to be a man. Adopting a narrative approach and analysis this research explores the stories of six Zulu men in seeking to elicit the aspects of their masculinity and show how these men negotiate an identity 'position' from the social narratives available to them. It was found that while the ideal Adult (responsible) man contrasts with the Young man's ('isoka' ) position there is a consistently hegemonic and patriarchal notion of masculinity.

- Description: During 1963 an area was mapped around Sidbury, 23 miles south- west of Grahamstown. The object of the survey was to examine stratigraphic problems, which included the nature of a large occurrence of shale south of Alicedale in a region previously mapped as Witteberg, and the relationship between Silcrete and Calcrete. During the invest igation evidence of the existence of two, possibly three , major thrust-faults and of extensive overfolding to the south was discovered. There is reason to believe, that movement on the Zuurberg Fault was initiated in pre-Cretaceous times, and renewed in the early Cretaceous. The Silcrete is shown to be related to the pattern of presentday drainage. Stone implements found embedded in the Calcrete suggest that it is of Recent age.
