- Description: This study sought to explore the perceptions of professional nurses regarding care of stabilised mental health care users in a general hospital setting. A qualitative, explanatory, descriptive and contextual design was used for the study. A non-probability, purposive sampling method was used to select 12 participants from the Cecilia Makiwane Hospital in Mdantsane. Data were collected through semi-structured interviews. The services of an independent interviewer were used to avoid any bias as interviews took place where the researcher is employed. The services of an editor were also used for language control (see Annexure H). The researcher repeatedly listened to the tapes used for data collection until completely satisfied with the interpretation of verbatim data. The research study was conducted in an ethically reflective manner and trustworthiness was ensured at all times. Four themes emerged from the analysis of the interviews: fear, stigma, myths and training. The researcher utilised the services of an independent coder who verified the identified major themes. The findings revealed that participants were fearful due to lack of knowledge, experience and psychiatric nursing skills. Participants feared because they lack knowledge about psychiatric medication and because mental health care users may have relapse. The participants also attached a stigma to mental health care users, which resulted in poor communication between participants and the stabilised mental health care user; a negative attitude towards mental health care users; and non-acceptance. Participants believed in myths about mental illness; they regarded it as contagious; and perceived mental health care users as dangerous. The participants strongly recommended that training should be provided to improve their knowledge and skills to enable them to care for stabilised mental health care users in a general hospital setting. The following should be facilitated: in-service training; adoption of a positive attitude; dispersal of myths and fear; education about referral systems; and allocation of specialist psychiatric nurses to medical wards for referral purposes with regard to complicated cases.

- Description: This study investigates the role of records management in the functioning of Magistrates courts in the Eastern Cape using Middledrift Magistrate court as a case study. The objectives were to determine types of records created, received and used at MMC, to describe the available infrastructure, security and preservation for the management of court records in MMC and to identify the obstacles encountered in management of court records at MMC. Forty respondents selected randomly and purposively were interviewed. The research findings showed that MMC creates, receives and maintains many court records, MMC is aware of the importance of managing court records from their creation to disposal, there are storages for semi- current and non-current records although there is lack infrastructure for managing court records. The study also revealed that there were occasional misplacement of court records, there was no case file tracking system and the security of records was satisfactory. This study recommends that MCC must have adequate storage space, training for the personnel and security systems to protect court records.

- Description: This study seeks to examine the naturalisation of refugees under international law with specific focus on the South African refugee system. The universalised nature of human rights and the difficulties of refugees finding new roots in host states form the basis of this study. This study takes a closer look at the South African refugee system and the path to naturalisation of refugees. It identifies policy and legal gaps in the process of naturalisation of refugees and argues that the practice as it stands today, fundamentally abuses the rights of refugees and questions South Africa’s good faith in meeting its international obligations under the 1951 Refugee Convention. It argues further that the biopolitical philosophy upon which South African citizenship is anchored is itself a hindrance to the realisation of efforts aimed at naturalising refugees and their descendants. The research methodology used in this study is non-empirical. This is so because the study is based on available data, information already available in print or on the internet. The study attempts to accomplish the above by undertaking an in-depth analysis of the history of refugees, the current position of naturalisation under international law, and identifies the inherent challenges. In the South African context, the study makes use of extensive statutory, constitutional and case law materials to justify that the current treatment of refugees in their quest for naturalisation is indefensible within the context of a human rights-based approach and the dictates of the Constitution. This study concludes by making recommendations that would help close the legal and policy gaps that obtain presently. These include amendments to the Refugees, Immigration and Citizenship Acts and strengthening policy implementation at the DHA. It is hoped that the recommendations will strengthen and evolve a human rights culture and bring refugee, immigration and citizenship laws in line with the Constitution. It will also pave the way for a more just and peaceful South Africa as she strives to meet her obligations under regional and international law.

The regulation of agricultural subsidies in the World Trade Organization framework : a developing country perspective

- Description: The Agreement on Agriculture (AoA) was adopted to eliminate the illegitimate use of tradedistorting agricultural subsidies and thereby reduce and avoid the negative effects subsidies have on global agricultural trade. However, the AoA has been fashioned in a way that is enabling developed countries to continue high levels of protectionism through subsidization, whilst many developing countries are facing severe and often damaging competition from imports artificially cheapened through subsidies. The regulation of subsidies in the World Trade Organisation (WTO) has been a highly sensitive issue. This is mainly due to the fear of compromising food security especially by developed countries. Developing countries have suffered negatively from the subsidy programmes of developed countries who continue to subsidize their agricultural sector. This position of the developing countries in the global trade system which has been described as weak, has drawn criticism that the WTO as it currently operates does not protect the interests of the weak developing nations, but rather strengthens the interests of the strong developed nations. The green box provisions which are specifically designed to regulate payments that are considered trade neutral or minimally trade distorting has grossly been manipulated by developed countries at the mercy of the AoA. Developed countries continue to provide trade distorting subsidies under the guise of green box support. This is defeating the aims and objectives of the AoA. The study examines the regulation of WTO agricultural subsidies from the developing countries’ belvedere. It looks at the problems WTO member states face with trade distorting subsidies, but focuses more on the impact these have on developing states. It scrutinizes the AoA’s provisions regulating subsidies with a view to identify any loopholes or shortcomings which undermine the interests and aspirations of developing countries. This is behind the background that some of the provisions of the AoA are lenient towards the needs of developed countries at the expense of developing countries.

- Description: Psychological well-being has a number of known benefits and is important for the quality of life of the elderly in particular. South Africa can be considered a religious country with the majority of citizens identifying with some religious orientation. The elderly are considered to be a more religious segment of the population, leading to a quantitative exploratory study being undertaken in order to ascertain whether a correlation exists between psychological well-being and religiosity/spirituality in the elderly institutionalised population of South Africa. The General Psychological Well-Being Scale and ASPIRES was administered to a convenience sample of 336 participants in the Eastern Cape Province. A significant but weak positive correlation was found between the variables of psychological well-being and religiosity. A difference was also found between White and African participants’ level of psychological well-being. An ANOVA was performed on the demographic information collected from participants. It was found that higher levels of education and access to private medical care were associated with higher levels of psychological well-being. A regression analysis was also performed on the data. It was found that although religiosity/spirituality does account for some of the variance, there were still a large number of other factors that influence psychological well-being in the elderly that were not captured in this study. Limitations of the study are that the results can’t be generalised to elderly residing at home. All of the participants also lived in urban areas and so differences may be found with rural elderly. Some further directions for research are discussed.

- Description: The purpose of the study was to examine the role of academic middle managers (AMMs) in the planning and implementation of curriculum change in private higher education institutions in Botswana. This study employed a mixed methods research approach which utilised a structured questionnaire and a semi-structured interview guide to gather data on AMMs‟ role in the planning and implementation of curriculum change in PHEIs in Botswana. SPSS version 21 was used for analysing quantitative data while thematic analysis was used for analysing qualitative data on the role of AMMs in the planning and implementation of curriculum change in PHEIs. The study showed that the role of AMMs in the planning and implementation of curriculum change in PHEIs was too complex and demanding because they spent most of their time on daily administrative routines instead of on core academic activities such as planning and implementing curriculum change in their departments. The AMMs in the PHEIs under study operated more like managers in academic departments than academics in management. As a result the study showed that AMMs faced more challenges than opportunities in their planning and implementation of curriculum change in PHEIs. The major challenges AMMs faced in the planning and implementation of curriculum change were a highly controlled and strict work environment, role conflict, lack of autonomy, role strain and heavy workloads which limited the time AMMs spent on the core business of managing curriculum change in their departments. The study also highlighted some of the strategies albeit a few, which, despite the numerous challenges AMMs faced, are used to try and make the planning and implementation of curriculum change by AMMs was to some extent successful. The study provided insight on the influence of AMMs biographical characteristics as well as the influence of AMM job requirements (such as having a detailed job description and having authority over curriculum matters) on how AMMs enacted their role in curriculum change. Based on the results of the study, a model to assist AMMs in the effective planning and implementation of curriculum change was proposed.

Therefore, this dissertation therefore discusses problems plaguing Agricultural Co-operatives in Nkonkobe. The qualitative methodology was used because it seeks to dig out in-depth information so as to understand the causes of food insecurity despite agricultural co-operatives and government assistance being in place. The food security situation was analysed using the sustainable livelihoods and basic needs approaches. The findings of the study reveal that agricultural co-operatives face a number of challenges. These include inadequate funds, poor market places, transport problems, shortage of farming equipment and insufficient water supply. In addition, the ability of agricultural co-operatives to make a worthy contribution to food security is being adversely hindered by poor implementation capacity and financial management. This in turn makes them unable to strengthen and expand their business operations. The study suggests that the government or the municipality should build sustainable water sources like dams as well as provide taps in the community to boost productivity all year round in the agricultural cooperatives hence guaranteeing food security in Nkonkobe Local Municipality,the Eastern Cape and South Africa at large.

Through the Burtonesque looking-glass : interrogating the psychoanalytic in Tim Burton's adaptation of selected children's texts

- Description: The primary aim of this thesis is to interrogate existing psychoanalytical theory, as well as to conduct research on ‘the Burtonesque’ in order to examine two of Tim Burton's filmic adaptations of classic literary works for children, namely: Alice in Wonderland (2010), an adaptation inspired by Lewis Carroll's Alice books, and Charlie and the Chocolate Factory (2005), based on Roald Dahl's novel of the same title. Firstly, the chapters will explore the psychological elements found in the original texts, which Burton amplifies in his onscreen adaptations by means of various stylistic and thematic techniques that have become known as ‘the Burtonesque’. Secondly, the ‘Burtonesque’ itself will be explored, and thirdly, by means of comparative analysis, the investigation will focus on the manner in which such aesthetics aid Burton in highlighting psychological concerns in his films, as well as interrogate his cinematic alterations to existing texts in order to further his purpose. As a keen enthusiast of psychology and having won awards within the field, Tim Burton, a foremost contemporary Hollywood filmmaker, in his adaptations of children’s classics, deliberately magnifies the psychoanalytic components that are often found in the tales. Through his unique interpretation, Burton brings the psychoanalytic approach to children’s stories to a new level. He explores certain themes such as death, childhood fantasies, psychological development and parental relationships, and makes use of specific artistic techniques that create a sense of the uncanny and defamiliarisation in the viewer. Due to his gothic cinematic approach, Burton is one of the most recognisable artists in his field, with a consistent vision that is concerned with cinematic and thematic aspects of his work, branding his films with a unique ‘Burtonesque’ quality that has become instantly identifiable. As a result of Burton’s psychological interest in children’s stories, Tim Burton’s film adaptations of the Dahl and Carroll classic children’s stories can be interrogated under a psychoanalytic lens. Psychoanalytic literary criticism is a method of literary analysis that is informed by the tradition of psychoanalysis established by Freud. In Burton scholarship, critical exploration should take the form of not only a close reading of the original text and analysis of the film version in order to come to a psychoanalytic interpretation, but by means of comparison of film and text, highlight the methods applied by psychoanalytic theory. A close comparative analysis of original literary works by Roald Dahl and Lewis Carroll, and Tim Burton’s filmic adaptations will be conducted in this study. Thereby, the manner in which Tim Burton employs specific techniques in order to emphasise the stories’ psychological components will be explored. Biographical information of Dahl and Lewis, as well as a short synopsis of their stories will be included in order to provide the context for psychoanalytical criticism. A discussion of ‘the Burtonesque’ will be provided, as well as a brief exploration of his adaptation history and Burton’s specific interest in psychology. Research methods to be applied in the analysis of the original texts and their film versions are psychoanalytic literary theory, drawing predominantly on the work of theorists: Sigmund Freud, Jacques Lacan and Carl Jung. A close examination of auteur theory, the unique voice Burton has established through his iconic cinematic techniques, now coined ‘the Burtonesque’, will also be applied to provide a fuller and rounder interrogation. The focus of this project is to investigate thempsychoanalytical elements found in the texts and films, in order to clearly illustrate how Tim Burton’s cinematic approach serves to highlight a psychoanalytic interpretation.

As a result of Burton’s psychological interest in children’s stories, Tim Burton’s film adaptations of the Dahl and Carroll classic children’s stories can be interrogated under a psychoanalytic lens. Psychoanalytic literary criticism is a method of literary analysis that is informed by the tradition of psychoanalysis established by Freud. In Burton scholarship, critical exploration should take the form of not only a close reading of the original text and analysis of the film version in order to come to a psychoanalytic interpretation, but by means of comparison of film and text, highlight the methods applied by psychoanalytic theory. A close comparative analysis of original literary works by Roald Dahl and Lewis Carroll, and Tim Burton’s filmic adaptations will be conducted in this study. Thereby, the manner in which Tim Burton employs specific techniques in order to emphasise the stories’ psychological components will be explored. Biographical information of Dahl and Lewis, as well as a short synopsis of their stories will be included in order to provide the context for psychoanalytical criticism. A discussion of ‘the Burtonesque’ will be provided, as well as a brief exploration of his adaptation history and Burton’s specific interest in psychology. Research methods to be applied in the analysis of the original texts and their film versions are psychoanalytic literary theory, drawing predominantly on the work of theorists: Sigmund Freud, Jacques Lacan and Carl Jung. A close examination of auteur theory, the unique voice Burton has established through his iconic cinematic techniques, now coined ‘the Burtonesque’, will also be applied to provide a fuller and rounder interrogation. The focus of this project is to investigate thempsychoanalytical elements found in the texts and films, in order to clearly illustrate how Tim Burton’s cinematic approach serves to highlight a psychoanalytic interpretation.

- Description: Tillage operations disrupt the soil structure resulting in aggregates of various sizes and altered bulk density. Moreover, tillage influences soil carbon pools and many other soil physical properties. The objectives of this study were to determine, in various South African soils under different tillage systems, the following. (1) Amount of aggregate-associated soil organic carbon (SOC), (2) soil compressibility, and (3) relationship between compressibility, texture and the aggregate-associated SOC. The soil samples used in this study were collected from six different sites in Eastern Cape Province, South Africa. Soil samples were taken from conventional tillage (CT) and no-till (NT) land. To keep the soil aggregates intact sampling was done using a spade and carefully carried to the laboratory in rigid containers. For SOC determination, treatments were the two tillage systems, CT and NT, and four aggregate sizes. The experimental design was completely randomized design with a factorial layout and was replicated three times. Aggregate-associated SOC was determined using Walkley-Black method. Proctor compaction test was used determine the dry bulk density with varying moisture content and consequently the maximum bulk density (MBD) and critical water content (CWC). The aggregate-associated SOC content differed with tillage system and was significant higher (p < 0.05) in CT than NT. The amount of aggregate-associated SOC was 1.67 times higher in CT than NT plots. The MBD ranged between 1.77 g/cm3 and 10.27 g/cm3 and the CWC ranged from 9.1 percent to 10.3 percent. The higher amounts of SOC in CT were attributed to the annual crop residue returns while the lower amounts of SOC in the NT fields were due to grazing. Therefore, tillage influenced the amount of aggregate-associated organic carbon irrespective of the resulting size of the aggregate. The positive relationship between tillage and aggregate-associated SOC challenges the conversion of land to no-till for carbon sequestration. The overall gradient for correlation between the MBD and CWC was negative with r2 = 0.23 and a p value of 0.0076. The compressibility curves indicated higher values under CT if the texture class was silt clay.

- Description: Mbira dzavadzimu music and performance practice has been in existence since the pre-colonial era. It played a crucial role in ritual and non-ritual activities of the Shona people of Zimbabwe. However, political, social and global influences as well as technological advancement have resulted in change of context and performance practice. Unfortunately, these have not been recorded for future generations. The major aim of the study is therefore to examine the change of context and performance practice of mbira dzavadzimu in Zimbabwe. This was achieved by reviewing mbira dzavadzimu music and performance practice within the modern setting of dandaro. I looked at change from a theoretical lens of the theory of diffusion, syncretism and mediatisation. The study was in the qualitative form superimposed on some case studies. Unstructured interviews, participant and non-participant observations were the main instruments used to collect data from both traditional and modern mbira performances. Data was also collected from museums, archives, radio and television stations. The study established that the changes in context and performance practice of mbira dzavadzimu in Zimbabwe were to a larger extent due to foreign influences such as colonialism, the coming of missionaries, modernisation, urbanisation, commercialisation, mediatisation, the use of modern technology and institutionalisation. Due to the aforementioned influences, the environmental settings, the change of context from sacred to secular, the relationship with ancestral spirits, musical practices, performance situations and quality of sound, have been modified and adjusted in response to the influences of the globalised world’s ever changing audience and performance space. In short, this has resulted in a shift of mbira performances from its traditional to modern settings, from the village to the city and onto the international scene with a new performer-audience setting. Various innovations were carried out on the instrument and its music as a result of the advent of modern technology. The use of microphones, modern amplification systems, recording studios, radio and television broadcast, audio and video cassettes, CDs, DVD, teaching of the instrument using audio and video instructional models and the use of internet sites in learning how to play mbira dzavadzimu and other instruments have become a reality. It has been evident from the study that urban and rural areas take up change in different ways and that in the former change is more pronounced than in the latter. Urban area communities are more “developed” than their rural counterparts because the former are more exposed to technological influences and the commercialisation of music. The study has also established that Zimbabwean mbira music is a good example of modern transculturality. The instrument and its music have played a major role in breaking down cultural boundaries and bringing the people of the world together for purposes of performing on the instrument. From the findings of this study, I attribute most of the changes to technologisation, for most of the changes that have taken place on mbira dzavadzimu were a result of the highly technologised way of life Zimbabweans now lead.

- Description: Introduction. A well-recognized problem exists when commonly employed tests developed in the United States (US) or United Kingdom (UK) are accepted unconditionally for use on local relatively disadvantaged populations, as these tests have questionable validity and therefore incur a high risk of misdiagnosis. Cross-cultural normative research has been conducted in South Africa on some of the Wechsler intelligence scales with respect to participants stratified for level and quality of education, age, race and language, including a study on the Wechsler Intelligence Scale for Children – Fourth Edition (WISC-IV) for learners with Grade 7 education (age 12 to 23). The aim of the current study was to conduct a partial duplication of the earlier WISC-IV South African norming study that specifically targeted a younger group of educationally disadvantaged children at a lower level of education. Method. Participants were Black Xhosa-speaking Grade 3 learners in the age range 8 to 9 (N =32 ), who were being schooled in the disadvantaged educational setting of the former Department of Education and Training (former-DET) schools. The WISC-IV results of the current study were statistically compared with the WISC-IV results from Shuttleworth-Edwards, Van der Merwe et al. (2013) study. Results. There was a significant lowering of between 20 to 30 IQ points relative to the UK standardisation on WISC-IV scores for this sample of Grade 3 Xhosa-speaking learners, replicating the earlier outcome for Grade 7 Xhosa-speaking learners relative to the UK standardisation. No differences were in evidence within the WISC-IV sample for the female and male participants on any of the indices. There was equivalence between the Grade 3 and Grade 7 Xhosa-speaking learners on all subtest and Index scores with the exception of the Digit Span subtest. Conclusions. The results confirm prior research indications of the negative impact of educational disadvantage on IQ test results and the need for this to be taken into account by the availability of socio- culturally relevant norms.

- Description: Savannas occupy 1/8 of the global land surface, support a large proportion of the world’s human population and the majority of its rangeland and livestock. Woody encroachment has been reported as the major challenge in these landscapes. This study describes the differences between three contrasting tree density classes in a semi- arid savanna with the view to developing an improved understanding of woody encroachment which is prevalent in this region. The study attempted to determine if there was a relationship between lateral root distributions at varying soil depths with increasing levels of woody encroachment, and to compare species composition and soil water profiles in these rangelands. Three homogeneous vegetation units, namely: sparsely encroached (HVU1), grassland (HVU2) and Albany thicket (HVU3) were identified for the study sites. A Trench method was used determine root biomass and a step point method was used to determine herbaceous species composition in all the HVUs. The results showed that more Decreaser species (especially Themeda triandra) were recorded in a sparsely encroached site (HVU1) and grassland site (HVU2), while Cynodon dactylon was mostly recorded in the thicket site (HVU3). Acacia karroo was mostly recorded in HVU1 while in HVU2 other woody species such as Coddia rudis and Grewia occidentalis were also recoded. HVU3 had the poorest basal cover (point to tuft distance) (22.60 cm) while HVU1 (9.93 cm) and HVU2 (7.73 cm) had moderate basal cover. The herbaceous standing biomass was significantly different across the HVUs. HVU3 was higher (1206.15 kg ha-1) than HVU1 (942.43 kg ha-1) and HVU2 (677.10 kg ha-1). The soil moisture content was significantly different between the HVUs, but was not significantly different between the depths (p< 0.05). High soil moisture content was recorded in HVU3 compared to other HVUs. The results of Analysis of Variance (ANOVA) showed that soil depth and the type of homogenous vegetation unit (HVU) had significant effects (p<0.01) on root biomass. The pair wise t-test showed that there were no significant difference in root biomass between sparsely encroached (HVU1) and grassland (HVU2) sites (p>0.05), but there were significant differences in root biomass between grassland (HVU2) and thicket (HVU3) site (p<0.05). The mean for total root biomass found in the study was 2.66 kg m-2. In all the trenches most of the root biomass was found in depth 1 (0-30 cm) which was 2.43 kg m-2followed by 1.32 kg m-2 in depth 2 (30-60 cm) and 0.49 kg m-2 in depth 3 (60-90 cm). According to the results on species composition, herbaceous biomass, basal cover, soil moisture content and the root biomass, Kwezana communal rangeland has a potential of running a sustainable livestock production enterprise if proper management practices can be implemented. To improve the rangelands of Kwezana communal rangelands, management such as proper resting, burning, proper stocking rates and physically clearing of bushes should be considered.
