- Description: Negative attitudes and stigmas against those diagnosed with mental illnesses have been found to prevail in modern society, despite the availability of effective treatments and attempts to educate people about mental health. Numerous studies have been conducted on the attitudes of various groups of people and communities towards mental illness. There is, however, limited research about student populations, particularly students registered for courses in the “allied health professions”. This study aimed to explore and describe the prevailing attitudes towards mental illness of a sample of the undergraduate Psychology student population (registered between 2nd and 4th year of study) within the Faculty of Health Sciences at a South African University. The procedure followed was an electronic intranet based survey, utilising the Community Attitudes to Mental Illness (CAMI) scale. The survey was accessed via the university’s student portal and links were sent via email to students to complete. A total of n=51 student responses were recorded and analysed. Data were quantitatively analysed using t-tests and Analyses of Variance (ANOVA). No statistically significant differences on the CAMI scales were found between the students in relation to the various student demographic variables such as age, gender, race or year level, and the CAMI findings. Overall, the sample of undergraduate Psychology students were shown to have favourable attitudes towards mental illness, which is potentially accounted for by their chosen field of study of Psychology. Education and knowledge about mental health were acknowledged as being most important in reducing stigma towards mental illness.

- Description: The study focused on attitudes of professional nurses towards the dimensions of quality care. Quality care is the main focus of the Department of Health in the Republic of South Africa. The researcher believes that professional nurses form the backbone of the whole health care fraternity; hence they are central to the study of quality care dimensions. The aim of the study was to determine and describe the attitudes of professional nurses towards the dimensions of quality care in the community health centres of the KingSabatha Dalindyebo sub-district. A quantitative descriptive design was employed to meet the objectives of the study. The non-probability purposive sampling method was used to select participants to provide information on the attitudes of professional nurses towards the dimensions of quality care in the community health centres of the King Sabatha Dalindyebo sub-district, Eastern Cape. From the target of 84 professional nurses who were employed at the five community health centres of King Sabatha Dalindyebo sub-district of the O.R. Tambo District, Eastern Cape Province, 70 (83,3percent) professional nursesresponded to the questionnaires. A self-administered questionnaire written in simple English was used to collect data from the professional nurses regarding their attitudes towards dimensions of quality care. The researcher adhered to the ethical standards of nursing research as described by the Democratic Nursing Organisationof South Africa regarding anonymity, confidentiality, privacy and quality research, according to which the names of professional nurses were not recorded on the questionnaires. The data were analysed using the Statistical Package for the Social Sciences (SPSS) computer software. The distribution of the results has been presented in tables and a bar graph. The results of the study revealed that the professional nurses of these community health centres had positive attitudes towards the dimensions of quality care.

- Description: The high sensitivities of modern radio telescopes will enable the detection of very faint astrophysical sources in the distant Universe. However, these high sensitivities also imply that calibration artefacts, which were below the noise for less sensitive instruments, will emerge above the noise and may limit the dynamic range capabilities of these instruments. Detecting faint emission will require detection thresholds close to the noise and this may cause some of the artefacts to be incorrectly detected as real emission. The current approach is to manually remove the artefacts, or set high detection thresholds in order to avoid them. The former will not be possible given the large quantities of data that these instruments will produce, and the latter results in very shallow and incomplete catalogues. This work uses the negative detection method developed by Serra et al. (2012) to distinguish artefacts from astrophysical emission in radio images. We also present a technique that automates the identification of sources subject to severe direction-dependent (DD) effects and thus allows them to be flagged for DD calibration. The negative detection approach is shown to provide high reliability and high completeness catalogues for simulated data, as well as a JVLA observation of the 3C147 field (Mitra et al., 2015). We also show that our technique correctly identifies sources that require DD calibration for datasets from the KAT-7, LOFAR, JVLA and GMRT instruments.

- Description: This research explored the contribution made by shelters in the psychosocial empowerment of survivors of abuse in the contemporary South Africa. Abuse of women is increasing at an alarming rate and government is not able to handle the task single-handedly. The study utilized convergent mixed methods approach (Creswell, 2014) with qualitative and quantitative approaches used in tandem; but with the qualitative approach being more dominant, while quantitative approach was less dominant. For research designs, the qualitative approach used a case study design; while the quantitative method utilized a mini survey design. On the unit of analysis, 52 participants participated in the qualitative sample, with the following sample distribution: 30 participants (15 from each shelter) participated using in-depth interviews, 10 participants (5 from each shelter) constituted a focus group discussion with 12 participants (6 from each shelter) interviewed as key informants. The quantitative approach had a sample of 100 samples women who were victims of abuse complete a mini survey based on questionnaire interviews. The study identified many factors that prompted women to go and reside in shelters from physical abuse and sexual abuse usually perpetrated by women’s spouses taking the larger share. Other important drivers included economic and emotional abuse. This resonates with some of the tenets of the critical feminist theory that an offender’s victimization of another person is an expression of domination and control (Brownmiller and Russell, 1975 in Wilcox 2010). Furthermore, the United Nations recognizes that violence against women is a manifestation of historically unequal power relations between men and women, contributing from male domination and discrimination over women. The study also established various psychosocial services provided to survivors of abuse. Such services were important in order to strengthen survivors’ coping capacities, raise their confidence and reinforce their decision-making processes pertaining to their lives. Some of these psychosocial services provided include provision of accommodation, nutritional meals, therapeutic counselling, basic counselling sessions, group work sessions, access to skills development programmes, assistance in maneuvering the judicial system, job placements, parenting skills, access to education and provision of preschool for their children and information and referrals. This study also managed to unearth and identify the various institutional and operational challenges that beset the running of the two selected shelters in Pretoria. Acutely, shelters suffer funding challenges, with funding either being inadequate or having to take so long before it is availed and, therefore, almost affecting the day to day operations of the shelters. These shelters were also challenged by donor regulations, inadequate infrastructure and a continuous increase of survivors and children in their care. Furthermore, the study identified the shelters’ effectiveness to raise survivors’ hope for the future; boost their confidence; improve their social functioning; provide emotional and practical support; offer them the requisite accommodation and meals; and also provided them with different kinds of skills that made them financially independent. The research recommended that a decentralization of shelters to rural areas across all provinces and the nation at large would go a long way in ensuring that all survivors will get the assistance they need. As the rural-urban migration takes its toll, the abuse of women also continues to increase. Funding is the key to the success of every project, and, therefore, the provision of enough and consistent funding and a sustainable plan to the shelters will ensure the smoothness of the provision of services and reduce staff burnout, reduce high staff turnover, and increase the stability of trained personnel. The study also recommends the government to consider subsidizing the salaries for the staff working in shelters so that their salaries would be on par with their colleagues in other organizations. Government should also facilitate the institution of shelters for survivors of abuse as some men feel that the issue of abuse focuses on females and therefore men shy away from accessing the services of the shelters.

It challenges the current methods and strategies implemented in correctional facilities in South Africa, their insufficiencies in rehabilitating criminals and preparing them for a return to society. A new solution to this social problem of crime and recidivism Is explored through this architectural thesis. This is achieved through providing an infrastructure with consistent methodologies that cater for unit operations using boot-camp rehabilitation, healthcare and vocational training provided all as a collaborative effort with the correctional services, municipal healthcare services and private N.G.O’s. An adaptive approach both in the program and architecture contributes to the objective of meaningful social re-integration. The research methodology implemented is a qualitative investigation, through the Interpretation of contemporary situations, various site visits, Interpretative sketches of existing structures, Technical analysis from firms. Interpretive and case study research is also used, as a background to the research body.

- Description: This study examined the relationship between bank competition and economic growth across South Africa, Russia and China. In this regard, the study conducted a comparative analysis which allowed for country differences and thus enhanced the provision of relevant policy guidance given how each of the country’s economic growth is reacting to changes in bank competition. To account for country differences, the study estimated a random coefficient panel (RCP) model using Swamy’s generalised least squares (GLS) estimators for the period 1999 – 2015. Across the three countries, bank competition and economic growth have been found to be positively related. In addition, bank competition has been found to be highly significant in influencing economic growth across the three countries. However, the extent of influence that bank competition has on economic growth differs in each country. Therefore, this study recommends that policies aimed at promoting competition in the banking sector of South Africa, Russia and China should be adopted in order to promote economic growth.

- Description: Women representation in management positions is described as a fundamental human right and an important means of fair democratic representation. This study intended to investigate the factors determining women upward mobility and their promotion to management positions. Included as variables were traditional gender roles, access to education and lack of mentoring and role models. The study followed the qualitative approach using snowball sampling and conducting semi structured interviews with ten Controlling Officers from different ministries and department of the Malawi Public Service to find out whether the variables under investigation indeed affect women upward mobility. Empirical evidence shows that traditional gender roles e.g. being mothers affect women upward mobility. Similarly, limited access to education is another factor that limits women access to managerial positions. Lack of mentoring and role models, especially where there are already few women at the top also affects women’s upward mobility. The study recommended that Malawi government should help women get scholarships that provide for their children. Furthermore, the government should provide flexible working hours especially for mothers. Women themselves should meet for a cup of tea where they can empower each other on the most important aspects of their job as chief executives; that is delivering a speech, making presentations and forming networks.

- Description: The national program for the development of next and new generation academic professionals (NGAP) aims to help Universities to diversify their academic teaching staff to be more reflective of the national demographics of the country. Through NGAP and policies of redress, a Historically White University would predictably introduce young black women into their academic teaching staff. This is a category of the population who would have been most affected by the exclusionary hiring policies that would have generally been in use in historically white universities before 1995, the year following the first democratic elections. The selection of staff according to criteria that has historically been used to exclude them is a policy which is widely considered to be a useful and necessary way to institute redress. While this half thesis does not disagree with this social and moral imperative, I find interest in the lack of focus on the emotional, psychological, spiritual and otherwise personal toll of the implementation of such a policy on those who are introduced through it and related policies. I believe there is a need to problematise the highly normative environments in which staff (to benefit from redress) are required to function. This half thesis examines the narrated experiences of three such staff members at Rhodes University with specific interest in their everyday experiences in an institution which has historically been tailored for (and in many cases is still run by) white, older male academics. The thesis indicates that the emotional and psychological effects and 'taxes' of being on an accelerated development programme may be worth noting and appreciating in order to think about the retention of black woman academics. The findings show that the complexity of younger black women's experiences within historically white universities such as Rhodes University requires equally complex and multifaceted strategies and programmes. These programmes should not only support these academics but also undermine existing exclusionary institutional cultures in order to facilitate true, deep transformational practice in historically white universities such as Rhodes University.

- Description: Marine ranching has been identified as an alternative to traditional aquacultural rearing and growing organisms for consumption. In the Eastern Cape, abalone ranching is a new and experimental industry. The aims of the research were to: first develop a GIS model to assist management in site selection for abalone seeding; and secondly to develop and standardize the sampling methodology in order to ground truth the sites, and assist in the monitoring and habitat identification of abalone. The GIS model developed in Chapter 3 was created using an unsupervised classification and fuzzy logic approach. Both vector and raster datasets were utilized to represent 7 different layers. Predominantly satellite imagery was used to classify the different substrate groups according to pixel colour signatures. The basic process was to apply a fuzzy rule set (membership) to rasters which gave an output raster (Fuzzification). The membership output rasters were overlaid which creates a single model output. It was found that model accuracy increased significantly as more layers were overlaid, due to the high variability within each of the individual layers. Model ground-truthing showed a strong and significant correlation (r2 = 0.91; p < 0.001) between the model outputs and actual site suitability based on in situ evaluation. Chapter 4 describes the investigation towards the optimal sampling methods for abalone ranching habitat assessments. Both destructive sampling methods and imagery methods were considered as methods of data collection. The study also evaluated whether quadrat and transects were going to be suitable methods to assess sites, and what size or length respectively they should be to collect the appropriate data. Transect length showed great variation according to the factor assessed. A transect of 15 metres was found to be optimal. Abalone counts showed no significant (p = 0.1) change in the Coefficent of Variance (CV) for transect lengths greater than 15m, and had a mean of 0.2 abalone per metre. Quadrat size showed a significant difference in functional group richness between quadrat sizes of 0.0625m2, and 0.25m2 but no difference between 0.25m2 and 1m2 quadrats for both scape and photographic quadrats. It was also found that between 5 and 10 replicates (p = 0.08) represents the functional groups appropriately using quadrats and that a 0.25m2 quadrat is most suitable for sampling. Chapter 5 describes the benthic community structure of Cape Recife shallow water reefs. Using the standardized methodology previously mentioned, 45 sites were assessed to identify the community structure. These sites were grouped into 5 different groups influenced by depth and substrate, as well as functional group composition according to a Wards classification. The community structure showed that depth and substrate play a significant role (p < 0.05) in the community type. There is also a significant relationship (p < 0.05) between complexity, rugosity, abalone presence and substrate. During this study the basic protocols for site selection and benthic community monitoring have been developed to support the abalone ranching initiative in the Cape Recife area. It has also provided a baseline of the benthic community in the ranching concession area which will be used as a benchmark for future monitoring efforts. The site selection, sampling, and monitoring methods developed during the course of this work have now been rolled out as Standard Operating Procedures for the ranching programme in this area.

- Description: Marine ranching has been identified as an alternative to traditional aquacultural rearing and growing organisms for consumption. In the Eastern Cape, abalone ranching is a new and experimental industry. The aims of the research were to: first develop a GIS model to assist management in site selection for abalone seeding; and secondly to develop and standardize the sampling methodology in order to ground truth the sites, and assist in the monitoring and habitat identification of abalone. The GIS model developed in Chapter 3 was created using an unsupervised classification and fuzzy logic approach. Both vector and raster datasets were utilized to represent 7 different layers. Predominantly satellite imagery was used to classify the different substrate groups according to pixel colour signatures. The basic process was to apply a fuzzy rule set (membership) to rasters which gave an output raster (Fuzzification). The membership output rasters were overlaid which creates a single model output. It was found that model accuracy increased significantly as more layers were overlaid, due to the high variability within each of the individual layers. Model ground-truthing showed a strong and significant correlation (r2 = 0.91; p < 0.001) between the model outputs and actual site suitability based on in situ evaluation. Chapter 4 describes the investigation towards the optimal sampling methods for abalone ranching habitat assessments. Both destructive sampling methods and imagery methods were considered as methods of data collection. The study also evaluated whether quadrat and transects were going to be suitable methods to assess sites, and what size or length respectively they should be to collect the appropriate data. Transect length showed great variation according to the factor assessed. A transect of 15 metres was found to be optimal. Abalone counts showed no significant (p = 0.1) change in the Coefficent of Variance (CV) for transect lengths greater than 15m, and had a mean of 0.2 abalone per metre.

- Description: Pregnancy is a normal physiological process for the majority of women. These women, their families and significant others normally expect a successful period of pregnancy, labour, delivery and arrival of a normal and healthy baby. However, some of these pregnant women may develop Gestational Diabetes Mellitus (GDM) during this period and if not managed properly, the mother and the foetus in utero are affected in a negative way: there is a likelihood of the mother and baby developing Type 2 Diabetes in the future and also, other risks such as preterm labour, and foetal macrosomia. In order to prevent such occurrences, I set out to develop a best practice guideline for the nursing management of GDM in military health institutions in Ghana in order to help enhance nursing care. The design for this research was qualitative, explorative, descriptive and contextual in nature. The research is organised in three phases: Phase one deals with the data analysis and discussion of the interviews with professional nurses and midwives and women with a history of GDM. The data collected from the interviews were transcribed, analysed and extracted with Tesch’s eight steps of coding used for the coding. The services of an independent coder were employed to assist with the coding process which led to the formulation of key themes. Semi-structured individual interviews provided a means of exploring the perceptions of professional nurses and midwives on the nursing management of GDM: in addition, women with a history of GDM were interviewed so as to elicit their views on the management they had experienced from professional nurses and midwives before and after being diagnosed with GDM. The trustworthiness of the study was ensured by conforming to Lincoln and Guba’s framework of credibility, transferability, dependability, confirmability and authenticity. An independent coder assisted with the coding process. Phase two deals with the Integrative literature review of available evidence-based clinical practice guidelines for the nursing management of GDM. Evidence-based clinical practice guidelines were searched and appraised with assistance from an independent appraiser and themes were then formulated. In Phase three, the themes from Phase one and Phase two were integrated for the development of a draft best practice guideline for the nursing management of GDM in military health institutions in Ghana. The draft guideline was given to an expert panel of reviewers for their comments and recommendations. These were considered in the development of the final best practice guideline for the nursing management of GDM.

- Description: Small businesses of which the majority are female-owned are the backbone of many economies across the globe. Despite the increasingly important role of female-owned small businesses to economic development and poverty alleviation, the growth of female-owned businesses in Uganda remains a major concern. The purpose of this study, therefore, was twofold – to identify business growth challenges of female small business entrepreneurs in Uganda and also to identify the strategies for overcoming these small business growth challenges to add to existing theory within the small business management field. The study followed a qualitative research with an exploratory descriptive case study design approach. A comprehensive international and national literature on female entrepreneurship, the Ugandan business environment, small business growth challenges in Uganda, and global best practice strategies for stimulating small business growth was conducted. Primary data were collected using face-to-face and telephonic interviews with semi-structured interview guides. Twelve (three female small business entrepreneurs and nine small business support specialists) participants were selected using purposive, theoretical, and expert sampling methods. The biographical profiles of the participants interviewed during the study were presented as case studies. Firstly, the biographical profiles of the three Ugandan small businesses (supermarket, restaurant and hairdressing salon) and the female entrepreneurs were presented. Secondly, the biographical profiles of the nine small business support institutions (two governmental, two funding, two training, one export promotion) and two business associations, as well as the profile of the small business support specialists were presented. Based on the content analysis of the qualitative interviews with the three female small business entrepreneurs, their current business status revealed that the female entrepreneurs have growth aspirations and aligned their goals towards it, but did not have strategies in place to effect business growth. Further still, based on the empirical results of the female small business participants, eight main challenges were identified as: lack of adequate business support and business skills training; demanding and costly business registration and trading license processes; high business taxation; access to finance; inadequate road infrastructure; family-related issues and cultural taboos. These participants also suggested some solutions to overcome these challenges. The small business support specialist participants either confirmed the challenges that specifically females experience or confirmed that they are perceived and not real challenges, or that it is not female-specific but generic to all small businesses. The study further established what female small business participants regard as possible strategies to the challenges experienced, while the small business support specialist participants could indicate which strategies have already been implemented and also suggest further strategies. It was concluded that although many of the challenges could apply to all small businesses, this study found that cultural taboos and family-related issues are a real challenge for female small business entrepreneurs. As seen in this study, these two main challenges can further influence some of the other challenges. It can influence whether qualifying for access to funding, having extra funding to pay for registration, licensing and tax, what the business is allowed to sell, and even the novelty of a female owing a business, never mind wishing to grow their businesses. Although some challenges such as discrimination against female entrepreneurs regarding access to small business support or funding is perceived, there are real infrastructure challenges such as rural road conditions, access to electricity and ICT. Several strategies are already in place in Uganda to assist all small businesses with business growth, but not necessarily just assisting female small business entrepreneurs. However, many of these strategies are work-in-progress and have not yet had the desired end result. This study made a contribution to knowledge by indicating that government-, skills training-, financial- and export promotion institutions, as well as business associations together with influential community members, can contribute significantly to the implementation of several strategies to promote female small business growth. In addition, the chapter on best practices of global developed – and developing countries provided insight into making well-informed practical recommendations that Uganda can implement to assist small businesses to grow and in particular females small businesses. These global best practice strategies for the growth of SMMEs as applied within the seven selected seven countries were elaborated on in detail with a clear indication of the responsible bodies in Uganda that can affect these strategies. The emphasis was on suggesting strategies that can be practically executed with relative ease in Uganda as a developing country. This study concludes that it remains the responsibility of female small business entrepreneurs to make the effort to grow their small businesses and turn their business visions into reality. They should write a business plan, search for and approach small business support institutions for assistance and engage in an extensive networking drive to grow their customer market and to search for opportunities to grow their business such as private-public sector partnerships or expansion into the international market. Awareness is not just the responsibility of the several small business support institutions in Uganda, but female small business entrepreneurs should actively scrutinise media reports in newspapers, the radio and television to obtain information regarding business support opportunities.

- Description: The motivation behind the research paper, “Between reproductive rights and access to reproductive healthcare services: Narratives of reproductive rights activists in South Africa” stems from the notion that civil society groups have often played a critical role in addressing social justice issues concerning women’s rights. Since 1996 after implementation of the Choice on Termination of Pregnancy (CTOP) Act, South Africa has frequently been praised for its progressive abortion laws that formally recognises women’s need for reproductive autonomy and equality. However, ineffective implementation has resulted in many women facing a combination of barriers to accessing reproductive healthcare services. Thus, resulting in some women opting for unsafe, illegal abortion services and placing their health and lives in danger. The purpose of the study, therefore, is to capture the perceptions of contemporary South African based reproductive rights activists and NGOs who engage in campaigns that seek to highlight the complex relationship between reproductive rights and access to such rights. Data for the study was collected through open-ended questionnaires in which participants provided their unique opinions as activists who regularly engage with the abortion and access issues in South Africa. Results from the study suggest that ineffective implementation of the CTOP Act can be attributed to a lack of political will to prioritise women’s sexual and reproductive rights, thereby further marginalising women in society. Results also point to the need for widespread support from civil society on women’s rights matters so that the State can more effectively be held accountable for catering to the most marginalised women in South African society.

- Description: This thesis examines the history of the Honde Valley area, in Mutasa District, along the Zimbabwe-Mozambique border. It uses two historic developments: the Zimbabwe liberation war and RENAMO insurgency to explore daily life and mundane experiences of the borderland communities, mainly from the late 1970s to 2016. Because earlier historians of these two historic developments have been much interested in studying the aspects of violence and suffering, this study extends the focus of analysis to the mundane experiences. I argue that in borderland areas, there are other wartime aspects of life worth investigating other than violence and suffering. In doing so, the thesis deploys the notions of conviviality and the everyday to understand the daily experiences of the Honde Valley communities during the disruptions caused to everyday life by these wars. Admittedly, twentieth century wars in Zimbabwe and Mozambique transformed the area that had previously remained at the fringes of colonial power from 1890-1950, into a new and bitterly contested ‘sharp end’ of the war. Nonetheless, peoples’ experiences during these wars cannot be understood merely in relation to violence and suffering. Furthermore, I argue that although some families were forcibly moved into liberation war “Protected Villages ”, they innovatively designed new mechanisms and alternative lifestyles in response to the state’s routinised control. The thesis concludes that beyond the confines of war-induced violence and suffering, Honde Valley communities used their borderland location to evade the pressures of war and continued with life.

- Description: Ice-free regions in Antarctica provide natural laboratories for investigating and modelling change in landscapes and ecosystems. The terrestrial ecosystems in western Dronning Maud Land are potentially critical to improve current understanding of polar ecosystems, however, they remain poorly represented and under-protected. Lichen habitats were used to elucidate geomorphic-biological feedbacks that shape the landscape’s topography and biodiversity, which in turn promote environmental heterogeneity. Environmental parameters acting on two landforms were measured to determine the colonisation and growth of lichens in niche habitats. The habitats were identified and characterised, and topographic heterogeneity was found to control lichen colonisation. Micro-topographical niches provide the most stable environments for colonisation, and are preferred habitats. Lichen-habitat interactions were species specific, and closely related to insolation and moisture availability. The bidirectional relationships between rock weathering and lichen colonisation was ascertained. Results showed that lichens are good indicators of landform heterogeneity, but also promote landform heterogeneity. Given the habitat preferences of specific lichen species, they provide proxy to evaluating environmental responses, especially environmental change. The findings of this research are to be used as baseline data for future studies exploring ecosystem development in emerging landforms.

- Description: Roughly 3% of the Earth’s land surface burns annually, representing a critical exchange of energy and matter between the land and atmosphere via combustion. Fires range from slow smouldering peat fires, to low-intensity surface fires, to intense crown fires, depending on vegetation structure, fuel moisture, prevailing climate, and weather conditions. While the links between biogeochemistry, climate and fire are widely studied within Earth system science, these relationships are also mediated by fuels – namely plants and their litter – which are the product of evolutionary and ecological processes. Fire is a powerful selective force and, over their evolutionary history, plants across diverse clades have evolved numerous traits that either tolerate or promote fire. Here we outline a conceptual framework of how plant traits determine the flammability of ecosystems and interact with climate and weather to influence fire regimes. We explore how these evolutionary and ecological processes scale to impact biogeochemistry and Earth system processes. Finally, we outline several research challenges that, when resolved, will improve our understanding of the role of plant evolution in mediating the fire feedbacks driving Earth system processes. Understanding current patterns of fire and vegetation, as well as patterns of fire over geological time, requires research that incorporates evolutionary biology, ecology, biogeography, and the biogeosciences.

- Description: Roughly 3% of the Earth’s land surface burns annually, representing a critical exchange of energy and matter between the land and atmosphere via combustion. Fires range from slow smouldering peat fires, to low-intensity surface fires, to intense crown fires, depending on vegetation structure, fuel moisture, prevailing climate, and weather conditions. While the links between biogeochemistry, climate and fire are widely studied within Earth system science, these relationships are also mediated by fuels – namely plants and their litter – which are the product of evolutionary and ecological processes. Fire is a powerful selective force and, over their evolutionary history, plants across diverse clades have evolved numerous traits that either tolerate or promote fire. Here we outline a conceptual framework of how plant traits determine the flammability of ecosystems and interact with climate and weather to influence fire regimes. We explore how these evolutionary and ecological processes scale to impact biogeochemistry and Earth system processes. Finally, we outline several research challenges that, when resolved, will improve our understanding of the role of plant evolution in mediating the fire feedbacks driving Earth system processes. Understanding current patterns of fire and vegetation, as well as patterns of fire over geological time, requires research that incorporates evolutionary biology, ecology, biogeography, and the biogeosciences.

- Description: Most research studies focus on foster children or foster parents, there is dearth of research on the impact of fostering on biological children. This aim of this study was to fill the gap in the literature regarding the experiences of biological children sharing a home with foster children. It also investigated how biological children perceive foster care and challenges encountered by children under foster care. This was achieved through a qualitative research approach. The study was conducted at Zwelitsha Township in King Williams Town. Data was collected through semi-structured interviews with thirty biological children of foster parents and ten social workers in practice. Two focus group discussions were held with twenty foster parents. A focus group discussion guide was used in collecting information during the discussions. Purposive sampling was used in the study and data was analysed according to themes. The major findings revealed that fostering has both positive and negative impacts on biological children and the foster family. Biological children find foster care placement as helpful to children whose parents cannot provide care and protection for children. They gain and learn new knowledge through fostering and are happy about their new siblings in the family since they have companionship. On the other hand, minority of biological children were ambivalent about foster care as they were uncertain between altruistic feelings of making a difference in the lives of needy children against the negative outcomes of fostering. One biological child was negative about foster care. This participant did not like the idea of fostering and did not describe any personal positive outcomes resulting from his fostering experiences. The findings revealed that biological children are unable to voice out their views and ideas regarding foster care placement. The findings also revealed that biological children are not passive observers on how fostering influences their daily lives. Instead, they use strategies to influence fostering processes, especially to protect their foster siblings for the fostering process to be successful, while also having feelings of responsibility for their foster siblings. The findings further suggest that despite the complex nature of the fostering task, professionals should recognise and acknowledge the input of biological children to fostering. It is, therefore, suggested more training should be provided to foster parents to continually include the opinions of their own children in fostering decisions.

- Description: The study determined the biomass yield, nutrient content and silage quality of forage sorghum varieties. Three varieties were used (King, PAN 868, and PAN 888), in a randomized complete block design (RCBD) with three blocks and three replicates per treatment at the University of Fort Hare research farm. The research study was conducted during the 2016/2017 growing season. The forages were harvested at flowering stage of growth. Biomass yields of fresh forage and dry matter yield were measured. Sub-samples were then dried, milled and analysed for nutrient content. Furthermore, the forage sorghum was ensiled and the silage was analysed for fermentation parameters and nutrient content. The fresh and dry matter biomass yield showed no significant differences (P>0.05) among the varieties. The highest fresh biomass yields were observed in PAN 888 variety was 13400 kg/ha, King had 12600 kg/ha and PAN 868 had 12600 kg/ha. The dry matter yield observed in PAN 888 was 4300.00 DM kg/ha, PAN 868 had 3633.33 DM kg/ha and King yielded 3533.33 DM kg/ha. The different sorghum varieties showed a significant (P<0.01) difference in some chemical composition parameters namely DM, NDIN and NSC. The different sorghum varieties had significant difference (P<0.01) in the silage fermentation parameters of pH, starch and lactic acid. The sorghum silage varieties were significantly (P<0.01) different in the starch fermentation with values of 0.001percent. The sorghum silage varieties were significant different for fermentation of lactic acid with values ranging from 1.99 to 2.62percent. However, PAN 868 and PAN 888 were not different from each other. Similarly, all varieties were different (P<0.05) in the pH with values ranging from 4.16 to 4.53. There were no significant (P>0.05) differences in CP, Fat, NDF, ADF, Hemicellulose, Ash, and ADIN content of the silages. The mineral composition (macro and micro) of the silage were not significantly (P>0.05) different among the varieties. In conclusion, the dry matter production and nutrient content of the three forage sorghum varieties were not significantly different. The silage fermentation quality showed significant (P<0.05) differences among the three sorghum varieties. Therefore, according to the results of this study PAN 888 is the recommended variety to grow in the semi-arid region of the Eastern Cape.

- Description: The Wouri River, situated in the Wouri Basin, is one of the main rivers of the Littoral Region in the city of Douala in Cameroon. It is a source of income and food for the population living around these areas. Since the 1990s, the fishing, transportation, irrigation and sand extraction activities have been impeded by the invasion of aquatic plants, specifically water hyacinth (Eichhornia crassipes [Mart.] Solms-Laubach: Pontederiaceae). Introduced in 1997 to the shore of Lake Chad, water hyacinth has invaded almost 114 ha of the Wouri Basin. Furthermore, Douala, the economic capital of the Cameroon and location for more than 70% of the country’s industries, uses the Wouri River and its tributaries to deposit its effluent and waste, which has worsened the problem of water hyacinth. This thesis examined the ecological and socio-economic impacts of water hyacinth in the Wouri Basin and its possible control. An increase in the nutrients in the water has provided water hyacinth with appropriate conditions for its fast growth during both the rainy and dry seasons. The availability of nutrients in these areas is enhanced by the constant, daily tidal fluctuation of water, providing enough water to the plant for easy nutrient uptake. A survey of the impacts of water hyacinth on aquatic plant communities in the Wouri Basin showed that this plant is able to out-compete native species. Assessment of the impact of water hyacinth on the abundance and diversity of plant communities indicated that at some invaded sites, 65% of the vegetation consisted of water hyacinth. Species found in association with water hyacinth with a high level of abundance-dominance were Pistia stratiotes L. (Araceae) (another invader), Commelina benghalensis L. (Commelinaceae) and Echinochloa pyramidalis (Lam.) Hitchc. & Chase (Poaceae). This component of the study also showed that habitats rich in water hyacinth were poor in diversity, while habitats without water hyacinth were rich in diversity, thus raising awareness of the importance of monitoring invasive aquatic weeds along the Wouri Basin, and of implementing correct control management of all invasive aquatic weeds. Communities living along the invaded rivers are well aware of the range of problems caused by the weed; because as the rivers and water bodies used for fishing, transportation, and sand extraction are progressively invaded by the weed, the riparian population is the first to feel the impact. The impact on people has been noticeable, with an increase in diseases, such as malaria, cholera, diarrhoea, typhoid, filariasis, schistosomiasis, scabies and yellow fever increasing the need for a medicine and hospitalization. Economic losses due to the management of invasive aquatic weeds were recorded, and the Ministry of Environment spent an estimated US$1 200 000 between 2010 and 2015 to manage this scourge. In 2016, an amount of US$160 000 was transferred to these regions to manage invasive aquatic weeds, especially water hyacinth, although manual clearing is still the only method used to control this weed. Isolation of fungi from diseased water hyacinth plants in the Wouri Basin revealed several fungal species, most of which have been isolated from water hyacinth species in water bodies elsewhere, which showed a higher diversity during the dry season than during the rainy season. These fungi included Acremonium zonatum (Sawada). W. Gams (Hypocreaceae), Alternaria eichhorniae Nag Raj & Ponnappa (Pleosporaceae), Chaetomium sp., Colletotrichum sp., Curvularia pallescens Boedjin (Pleosporaceae), Curvalaria sp., Epicoccum nigrum Link (Pleosporaceae), Fusarium sp., Pithomyces chartarum fBerk. & M. A. Curtis) M. B. Ellis (Montagnulaceae), to a lesser extent Myrothecium roridum Tode ex Fr. (Incertae sedis) and Nigrospora sp. Although never released in Cameroon, arthropod biological control agents (Neochetina eichhorniae Warner (Coleoptera, Curculionidae) and N. bruchi Hustache (Coleoptera, Curculionidae)) were present, but their populations were relatively low. The slow spread of the insect population was explained by several factors, among them the tidal fluctuation of water, which has an impact on the population growth of the weevils. Whilst adults may be able to survive tidal fluctuations, larvae are severely impacted by them, contributing to the slow success of biological control. In this study, a significant increase in pathogen-induced disease severity and incidence was noted when Neochetina eichhorniae weevils were present, possibly because larvae tunnelling on the petiole created openings for the penetration of fungal spores. This study highlights the negative impacts of water hyacinth, on the environment, people, and thus economy of Cameroon. The presence of biological control agents and pathogens offers Cameroon the possibility of initiating and properly implementing the biological control option, or an integrated management solution, to manage water hyacinth in the Wouri Basin, and in the rest of Cameroon.

- Description: The core of the commercial relations between the United States (US) and Sub-Saharan African (SSA) countries is primarily based on the advancement of unilateral preferential treatment as envisaged under the African Growth and Opportunity Act (AGOA). AGOA is a bipartisan US legislation promulgated to govern the North-South agreement between the US and SSA countries. Notably, AGOA can be categorized as an exception to the Most Favored Nation (MFN) clause of the General Agreement on Tariffs and Trade (GATT) and consequently under the legal framework of the World Trade Organisation (WTO). The US through the AGOA Extension and Enhancement Act (TPEA) has prolonged the lifespan of AGOA to 2025 in consonance with AGOA and other relevant US legislation. However, there is an ongoing debate as to whether AGOA is working to the advantage or benefit of the eligible SSA countries. This is due to several problematic issues which inter alia relate to the legitimacy of the unilateral preferential treatment, the applicable Rules of Origin (RoO) and the requirement for adoption of robust intellectual property protection regimes as impediments to the enjoyment of AGOA duty and quota free benefits. This study will thus examine the pertinent legal issues underpinning the granting of unilateral preferential treatment in favour of the SSA countries under AGOA and assess the extent to which AGOA complies with or fulfills the purposes and objects of the Enabling Clause.

- Description: In the South African Qualifications Authority and Rhodes University (SAQA-Rhodes) partnership research it was found that ‘researching the boundary’is an important unit of analysis in learning pathways research (see Papers 1 and 2 in this Bulle-tin). The researchers have argued that this focus has rele-vance for discussions on articulation, as articulation is a boundary crossing practice39. However, to understand boundary crossing processes, it is important to understand what the boundaries are in learning pathways research and to understand how these boundaries were developed. Bounda-ries in learning pathways are both social and material and are constructed by people’s actions and practices, and can only be resolved through people’s actions and practices. This pa-per–Paper 5–considers the manner in which social-material factors are ‘boundary makers’ in learning pathways, affecting access, mobility, progression and articulation possibilities, with specific reference to articulation between workplace experi-ences and contexts on one hand, and education and training systems on the other. The paper argues for a perspective on the social-material that includes the Critical Realist concept of ‘absence’(Bhaskar, 1993) as an important shaping force in learning pathways research (see Paper 4, in this Bulletin). By identifying ‘boundary making’processes and factors, as articu-lated through ‘voices in the workplace’[one perspective on this issue], the paper identifies key areas for ‘boundary cross-ing’practices in the South African National Qualifications Framework (NQF) system and its associated sub-systems.
