- Description: This paper articulates the patterns and feel of graduate underemployment in Mthatha, a South African town in the Eastern Cape Province. Foregrounded on Peter Blua’s Social Exchange Theory, this study adopted a quantitative approach. A sample of 60 respondents was drawn from underemployed graduate population through a combination of stratified and random sampling techniques. Data collected from survey (questionnaire) were analysed with appropriate tools in the Statistical Package for the Social Sciences. The study found that majority of underemployed graduates are between 21 and 25 years of age, married, hold bachelor’s degrees in Social Sciences. Gender, qualification type and level of qualification have no significant influence on determining underemployed graduates’ choice of occupation as single and combined variables or factors. While only very few (5%) of the underemployed graduates are never happy at work, femaleness, older graduates, Africans, higher qualification, higher basic salary and longer years of underemployment best predict happiness at work, although not at significant level, except for basic salary. A majority of graduates (73.3%) do sometimes consider leaving their current jobs, even when there are no alternatives. This is influenced by maleness, older graduates, being Whites, higher qualification, lower basic salary and lower years of underemployment. Lack of networking was found to be the most important factor in graduate underemployment, followed by lack of experience and gender not being significant. This study recommends policy intervention by state, where there is legislation that provides for entry level jobs that may not require previous experience. Also, there should be another legislation that protects the underemployed through salary regulation and incentivising of employers that engage workers in such capacity. Keywords: Underemployment, Youth, Graduates, South Africa.

- Description: The aim of this study was to explore issues concerning dispositions of crime-reporting behaviour of both witnesses and victims and comes against a backdrop of a rise in crime levels in South Africa. The study specifically examined the discouraging and encouraging factors for crime reporting in Mthatha area in the Eastern Cape Province of South Africa. A quantitative methodology was adopted, wherein a closed-ended questionnaire was used to gather data from 120 respondents. The result of the analysis revealed police absence of loyalty to citizens, lack of support for victims and lack of follow-up on reported cases as the major factors which discourage citizens from reporting crimes to the police. Further regression analysis confirmed gender, race, location of respondents and socio-economic status as significant predictors that influence discouragement. As regards the encouraging factors, overall, the citizens’ collective responsibility for safe communities was viewed as the major drive for reporting crimes to the police. From the findings, it can be concluded that poor police-public relations is the main driver for non-reporting of crime. The study recommends strengthening of police-public relations in order to encourage citizens to report crime.

- Description: Terminaliamide (1), a new ceramide was isolated from the roots of Terminalia mantaly H. Perrier (Combretaceae) along with 4 known compounds (2–5). The structures of the compounds were elucidated using 1D and 2D NMR spectroscopy analysis and mass spectrometry. Compound 1 exhibited moderated antibacterial activity towards Staphylococcus aureus with MIC value of 62.5 μg/mL. The crude MeOH extract (TMr) highly reduced Plasmodium falciparum growth with an IC50 value of 10.11 μg/mL, while hexane fraction (F1) highly reduced Trypanosoma brucei brucei growth with an IC50 value of 5.60 µg/mL. All tested samples presented little or no in vitro cytotoxicity on HeLa cell line. The present work confirms that T. mantaly is medicinally important and may be used effectively as an antimicrobial, an antiplasmodial and an antitrypanosomial with promising therapeutic index.

But the 2019 volume takes a much wider viewpoint including, as it does, twenty chapters by forty-two authors who are academics and academic developers across institutional types from Australia, Canada, South Africa, the United States of America, the United Kingdom, and the West Indies. Quinn and Vorster (2019: 2) state in Chapter One that the purpose of the book is 'to share theoretical perspectives and practical ideas for ways in which academic developers (and academic leaders) can work in partnership with lecturers and students to respond to the urgent calls for curriculum transformation and decolonisation'. This captures the four threads that run throughout the collection.

- Description: Many studies have considered job satisfaction and its antecedents in the profit making sector. These studies have provided a number of factors that influence job satisfaction including autonomy, compensation, growth opportunities, leadership styles, task variety and so on. There are numerous factors that have been discovered to positively influence job satisfaction. Interest in job satisfaction arises from the fact that productivity and other favourable organisational outcomes such as service delivery and quality of outputs have been found to associate with job satisfaction. This study followed a quantitative approach based on a Likert questionnaire to collect data on the antecedents of employee job satisfaction within a Higher Education Institution (HEI) in South Africa. It was established that antecedents of job satisfaction in the HEI resembled closely those established in the literature. It is recommended that HEI should consider factors such as remuneration, task variety, work autonomy, good workplace relations and leadership styles to foster employee motivation. Keywords: Job Satisfaction, Higher Education Institutions, Human Capital, Productivity

- Description: Herein, we present syntheses of three asymmetrical zinc(II) phthalocyanine (ZnPc) complexes and hydrothermal synthesis of cobalt tungstate nanoparticles. The ZnPc derivatives were covalently linked to cobalt tungstate nanoparticles. Photophysical and photochemical behaviour of Pcs and nanoconjugates were investigated. The nanoconjugates generated higher triplet quantum yield and singlet oxygen quantum yield than the ZnPcs alone. Furthermore, in this paper photocatalytic efficiencies of ZnPc complexes and nanoconjugates were investigated for the degradation of methylene blue and higher photocatalytic behaviour was observed for the conjugates. The kinetic model was used to study photocatalytic behaviour of all the prepared photocatalysts.

- Description: Asymmetrical Zn(II) phthalocyanines: mono (4-carboxy phenoxy) tris (phenylazo phenoxy) (1), mono (4-amino phenoxy) tris (phenylazo phenoxy) (2), mono (4-propanoic acid phenoxy) tris (phenylazo phenoxy) (3) zinc(II) phthalocyanines are synthesized and covalently linked to mercaptohexanol (mph) or mercaptopropionic acid (mpa) functionalized dimerized silver-magnetic nanoparticles (Ag-M). Complexes 1 and 3 are covalently linked to nanomaterials via ester bond whereas complex 2 is covalently linked to nanoparticles (NPs) via amide bond. The conjugates of complexes 1–3 with NPs gave higher singlet oxygen quantum than the Pcs alone. Electrospun fibers were fabricated from polystyrene (PS) solutions containing complexes 1 to 3 and their conjugates. The functionalized PS fibers were used for the phototransformation of dibenzothiophene. The increase in photocatalytic properties of phthalocyanines was observed in the presence of Ag-M with 3 alone and its conjugate with mph capped silver-magnetic nanoparticles showing the larger catalytic activity towards the transformation of dibenzothiophene.

Metal tungstate nanoparticles, capped with glutathione were prepared and characterized using analytical techniques. Complexes were covalently linked to nickel tungstate (NiWO4) and bismuth tungstate (Bi2WO6) through an amide bond. The complexes and the conjugates with nanomaterial were evaluated for singlet oxygen generating ability. Complexes 1–2 and their conjugates generate higher singlet oxygen compared to 3 and its corresponding conjugates. The conjugates show degradation of dibenzothiophene (DBT) in fuel with shorter half-lives and greater initial rate values compared to phthalocyanines alone.

- Description: Background: The South African department of health recently introduced subdermal Implanon contraceptive implant with the aim to reduce teenage pregnancy and maternal mortality. First used in all public healthcare facilities across the country since early 2014, this method of contraception has been described as highly effective. However, some women have reported unbearable side effects, forcing them to remove the contraceptive implant early before its expiry date. Negligible emphasis has been placed on staff training and development to equip the nurses with new protocol and policies on Implanon. Objectives: The objective of this study was to explore experiences of women using Implanon as method of contraception at a selected primary healthcare facility in KwaZulu-Natal province of South Africa. Methods: A qualitative, descriptive and exploratory study design was used. A purposive sampling technique was used and a sample of seven women aged between 15 and 50 years was selected for this study. Semi-structured interviews were used in the data collection process. The Tesch’s method for data coding and data analysis was utilised. Necessary ethical measures were taken to ensure that the study is trustworthy. The study was conducted at Community Health Centre, KwaZulu-Natal between June 2017 and December 2018. Results: The findings showed that some participants were still willing to continue using this method of contraception regardless of the unwanted side effects. Major side effects reported were heavy menstrual bleeding, pain and discomfort, weight loss, insomnia and decreased sexual interest, which resulted in most participants stopping the use of Implanon. Conclusion: Most of the participants’ experience unwanted side effects because of poor screening, counselling and support. There is a clear demand to develop a screening tool and facilitate training of healthcare workers when initiating the use of Implanon.

- Description: Against the backdrop of workplace restructuring globally, post-Apartheid South Africa is experiencing consistently high levels of unemployment, the deterioration of employment security, and limited improvements in earnings. This trend in the proliferation of low-paid, unstable and otherwise insecure employment has given rise to a segment of the literature that is centred on the growing precariousness of work in a number of different contexts. This thesis reviews empirical work on the changing nature of labour-intensive production in the past two decades, with particular focus on the trends in non-standard, informal and precarious employment. Further, the thesis examines the shift in the gender structure of South Africa’s manufacturing sector and how it affects the share in the benefits of employment, particularly with regard to social reproduction. In so doing, the thesis expands the critical theoretical narrative about the challenges of labour under neoliberalism by providing an intersectional perspective of precarious work in post- Apartheid South Africa.

Further, the thesis examines the shift in the gender structure of South Africa’s manufacturing sector and how it affects the share in the benefits of employment, particularly with regard to social reproduction. In so doing, the thesis expands the critical theoretical narrative about the challenges of labour under neoliberalism by providing an intersectional perspective of precarious work in post- Apartheid South Africa.

- Description: Domestic service has long been a major sector of the South African labour market, for black women particularly, who must support their family and children. Existing research has stressed the way in which race, class and gender has shaped the oppressive character of domestic service in South Africa. In this narrative study a new slant is provided on this existing theoretical discussion of domestic labour, one that is focused on exploring the agentic human being beyond ‘the servant question’. This study uses narrative interviews with domestic workers in Makhanda/Grahamstown in the Eastern Cape province of South Africa to show how we can expand on potentially limited or constricted passive ‘domestic worker identities’ and ideas/beliefs about women who do domestic work. A performative and positioning narrative analysis is used to explore the subject positions of domestic workers in their stories about their childcare arrangements. This analysis examines multiple shifting identities and positions that are used by domestic workers in relation to their maternal subjectivity and their audience (here, a white trainee-psychologist esearcher), while highlighting the significance of narrative methodology in making these positions visible. The areas of focus were their history, experience of domestic work, life outside of domestic work, family network/dynamics and personal childcare arrangements. Under these areas of focus the following was analysed: the ways in which the storyteller positioned herself in her narrative, how she compared/contrasted or located herself in relation to the other, claims of identity that were made, what she incorporated or purposefully left out, words and phrases that were chosen, which sections of talk were embellished or elaborated on and appeals that were made to the interviewer (Riessman, 2002). Through exploring the micro-practices of domestic workers’ lives the study found that there were various subject positions constructed and used by this group of women. Findings showed that domestic workers positioned themselves actively as breadwinners, good mothers who give their children opportunities that they were not given, nurturers and crafty mothers who secure good care for their children. In contrast to these active subject positions, positions of sacrifice were performed when domestic workers spoke about leaving their young children in the care of another while they worked. The study also found that participants managed complex positions of disappointment and unmet expectations for a better life in the new South Africa by using narratives of resistance and agency. In certain instances, identity appeals were made to the interviewer that they, and other women who do domestic work, are entrepreneurial and creative with their income and possess skills outside of their day-to-day household cleaning jobs. This was interpreted as an attempt to extend the domestic worker identity positioning beyond the traditionally accepted notions of unskilled/uneducated women who do domestic work. In the study this allowed for more subject positions to be taken up in terms of identities and selves, beyond just being a “domestic worker”.

- Description: Sediment source fingerprinting using environmental magnetism has successfully differentiated between sediment sources in different regions of South Africa. The method was applied in the natural landscape of the Kruger National Park to trace sediment sources delivered to four reservoirs (Hartbeesfontein, Marheya, Nhlanganzwani, Silolweni) whose contributing catchments were underlain by a range of igneous, metamorphic, and sedimentary rocks. This research attempted to evaluate the impact of vegetation, lithology, and particle size controls on the ability of magnetic signatures to discriminate between lithology-defined potential sources. Potential source samples were collected from each lithology present in all catchments, except for the Lugmag catchment where the lithology was uniform, but the vegetation type varied significantly between woodland and grassland. One sediment core was taken in each of the four catchment reservoirs where there was more than one lithology present in order to unmix and apportion contributing sediment sources. Sampling time in the field was often restricted to short periods, dependent on anti-poaching activities and movement of free-roaming wildlife across the Park. This occasionally led to the sub-optimal collection of enough source samples to capture source signature variability. Mineral magnetic parameters were unable to discriminate between vegetation-defined sediment sources in the Lugmag catchment (homogenous underlying lithology) but were able to discriminate between lithology-defined sediment sources (to varying degrees) in the other four catchments. The contributions of each lithology-defined sediment source were estimated using a straightforward statistical protocol frequently used in published literature that included a Mann-Whitney U or Kruskal-Wallis H test, mass conservation test, discriminant function analysis, and an (un)mixing model. A contribution from each lithology source to reservoir sediment was estimated. Connectivity was a significant factor in understanding erosion in each of the catchments. Both longitudinal (e.g., drainage density) and lateral connectivity (e.g., floodplain - river) were important. Travel distance of eroded sediment to reservoirs was also an essential element in two of the four catchments. There are no defined floodplains, so channel bank soils are very similar to the catchment soils. Therefore, channel bank storage potential would be similar to the storage potential within the catchment. Vegetation played a crucial role in protecting soils, by reducing ii erosion potential as well as trapping and storing sediment, thereby interrupting lateral connectivity. Underlying geology and soils are determining factors of vegetation type and density. A published study estimated catchment area-specific sediment yields for different KNP catchments, including the Hartbeesfontein, Marheya, Nhlanganzwani and Silolweni catchments. The published data was used in combination with the (un)mixing model source contribution estimates of this thesis to determine specific sediment yields by lithology, i.e., for each catchment source. The polymodal particle size characteristics of the sample material led to an investigation into particle size controls on the ability of magnetic signatures to discriminate between potential sources. Due to time constraints, only the Hartbeesfontein and Marheya catchments were tested for grain size differences. For each catchment, one bulk sample was created for each lithology source. This bulk sample was divided into 10 subsamples. The samples were then fractionated into four particle size fraction groups: coarse (250 – 500 μm), medium (125 – 250 μm), fine (63 – 125 μm), and very fine (<63 μm). Reservoir samples were also bulked to create 10 down-core samples for each reservoir, and the samples were also fractionated into the four fraction groups. The same statistical protocol was applied to the fractionated samples and contribution estimates were obtained by lithology for each particle size fraction group. The goodness of fit and uncertainty of the (un)mixing model varied in each catchment, with the two measures of accuracy often showing an inverse relationship. The fractionated modelling estimated the same primary source in the two catchments as in the unfractionated modelling. However, additional information on the secondary and tertiary sources was obtained. Connectivity remained a significant factor in interpreting the results of the fractionated analysis. Specific sediment yields were estimated for each catchment source per particle size fraction group. These sediment yields provided a deeper understanding of sediment transport through a catchment and which particle size groups are most important in catchment erosion. An original contribution to research was made by estimating source contribution estimates for the four reservoirs, quantifying sediment yields for each catchment lithology and then for each catchment lithology by particle size. Mineral magnetic tracing of the catchments was applied for the first time in this region of South Africa. , Thesis (PhD) -- Faculty of Science, Geography, 2021

- Description: Although art therapy is recommended in management programmes for individuals with a diagnosis of schizophrenia, calls have been made for more detailed explanations as to how artmaking is working. This study responds to those calls by considering the artmaking experiences of 15 mental health users with a diagnosis of schizophrenia, resident at a forensic, mental health facility in South Africa. A phenomenological approach was chosen because of its focus on lived experiences, suited to explore the embodied and pre-reflective experience of studio-based artmaking. Dialogical and narrative understandings were subsequently incorporated to account for more reflective aspects of the artmaking experience. Two main participant descriptions of artmaking, centring on feeling at home and on doing something meaningful, guided the phenomenological lifeworld method in analysing the data (interviews, artworks and field observations in art groups and exhibitions), along selected dimensions of lived experience, namely embodiment, temporality, spatiality, sociality and selfhood. These findings lend support to new phenomenological research which suggests that artmaking intersects with disrupted abilities for perceptual engagement underlying manifestations of schizophrenia symptomology. This research supports assertions that artmaking has the potential to support the minimal sense of self and expand possibilities for renewed embodied and more reflective meaning-making. Explanations of findings centred around the distinct artistic style of each participant, as well as their artworks which revealed individual lifeworlds including a variety of self-positions. The inherent properties of the completed artworks also provided possibilities for renewed experiences of sociality. Additional support for the findings is drawn from recent research in the fields of early neurodevelopmental trauma, and trauma research findings within the art therapy field.

- Description: Economic growth is often assumed to improve happiness for people in low income countries, although the association between monetary income and subjective well-being has been a subject of debate. We test this assumption by comparing three different measures of subjective well-being in very low-income communities with different levels of monetization. Contrary to expectations, all three measures of subjective well-being were very high in the least-monetized sites and comparable to those found among citizens of wealthy nations. The reported drivers of happiness shifted with increasing monetization: from enjoying experiential activities in contact with nature at the less monetized sites, to social and economic factors at the more monetized sites. Our results suggest that high levels of subjective well-being can be achieved with minimal monetization, challenging the perception that economic growth will raise life satisfaction among low income populations.

- Description: Sternophysingidae Holsinger, 1992 is a monotypic subterranean amphipod family endemic to Namibia and South Africa. It currently has eight described species under the genus Sternophysinx. The species in this family are considered narrow endemics, having only been identified using morphological characters. However, the apparent wide distribution of certain species, reported in several subterranean waters in different provinces, suggests that our current taxonomic understanding of these species needs to be completed, thus needing revision. Further, detailed knowledge of the distribution and phylogenetic relationship between species of this taxon still needs to be improved. This study aimed to use integrative taxonomy to analyse both morphology and molecular biology to study hidden diversity and to further our understanding of the distribution in this taxon. The available morphological keys were used to identify species, and 12S rRNA was also used to investigate the relationships of Sternophysinx species and delimit species boundaries. The study primarily aimed to use mitochondrial cytochrome c oxidase subunit I (COI). However, due to technical issues such as getting the correct primers, this study's aims were altered, and 12S was used instead of CO1. However, the process of getting CO1 sequences is still ongoing, and the results will be made available elsewhere. The current study aimed to visit all the type localities of the seven species of Sternophysinx reported in South Africa, including all known localities in which these amphipods have been recorded in the past. Nevertheless, this study did not get samples from Nelspruit, De Hoop Nature Reserve, and Nash Nature Reserve, which cover type localities of S. travaleensis, Matlapitse and Chaos cave that harbours S. calceola. Instead, the current study added five new localities Graaff-Reinet, Beaufort West, Hogsback, Makhambathi Nature Reserve and Ntsikeni Nature Reserve, for the distribution, including two new provinces (i.e., Eastern Cape and KwaZulu-Natal) that had records of this genus in the country. Three delimitation methods, Assemble Species by Automatic Partitioning (ASAP), Bayesian implementation of the Poison Tree Processor (bPTP) and Automatic Barcode Gap Discovery (ABGD), were used to identify cryptic species within Sternophysinx. Phylogenetic analyses and three delimitation methods (ASAP, bPTP and ABGD) revealed considerable hidden cryptic diversity within this Sternophysinx. Preliminary morphological examination revealed at least two species as undescribed from Bakwena and Sterkfontein caves, and several that were morphologically identified using the current taxonomic keys did not match with the molecular analysis. For example, S. basilobata from three different systems, Boesmansgat cave (Northern Cape), Beaufort West (Western Cape) and Potchefstroom (North West), was in genetically different putative species. The same is true for S. robertsi and S. alca in Ficus and Peppercorn cave in Limpopo. Overall, the results of the current study demonstrate the need for a comprehensive integrative taxonomic revision of Sternophysinx. These findings suggest that S. basilobata is a complex of distinct lineages and requires further study. On the other hand, species delimitation methods suggested that there are 12- 14 candidate species (Figure 2.5). Lastly, this study investigated the threat posed by the invasive koi fish introduced to an important cave, Boesmansgat cave in the Northern Cape, which is a type locality of two endemic species (S. megacheles and S. basilobata). Stable isotope (δ13C and δ15N) and gut content analyses of the fish were investigated to establish whether this invasive fish feed on these critical creatures, thus endangering their long-term survival. Stable isotope signatures and the stomach gut content proved to be helpful in determining the diet of the koi fish, revealing it to be an omnivorous feeder with high invertebrate preference, including amphipods. These results indicate that the introduction of koi fish in the Boesmansgat cave threatens the long-term sustainability of these amphipods and other invertebrate assemblages in this cave. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2023

- Description: Background: After 26 years into democracy and 20 years of the new local government operations, the state of the majority of municipalities in South Africa still leaves much to be desired, as they are plagued with maleficence. What is concerning is that these negative tendencies that are troubling local government occur even under the watchful eye of the municipal public accounts committees (MPACs). Aim: The aim of this study was to evaluate the composition and the role of MPACs, which have experienced a number of challenges since they were introduced in response to the widely held perception of the culture of lack of accountability in South African municipalities. Methods: This article is theoretical in nature, and it draws its arguments from secondary data in order to understand the composition and the role of MPACs, including its challenges. Results: This study regards the composition of the MPAC as lacking the necessary vigour to be efficient and effective in executing its duties, particularly when considering the challenges and political influences that it tends to face in its operations. Conclusion: The study concludes that there is a need for re-engineering of the composition and the role of the MPAC in order to ensure that it executes its functions efficiently and effectively. Consequently, the study recommends three cardinal pillars that must be given attention in re-engineering the MPAC: policy, authority and power. Keywords: Internal accountability; maleficence; municipalities; municipal public accounts committees; re-engineering

- Description: Background: After 26 years into democracy and 20 years of the new local government operations, the state of the majority of municipalities in South Africa still leaves much to be desired, as they are plagued with maleficence. What is concerning is that these negative tendencies that are troubling local government occur even under the watchful eye of the municipal public accounts committees (MPACs). Aim: The aim of this study was to evaluate the composition and the role of MPACs, which have experienced a number of challenges since they were introduced in response to the widely held perception of the culture of lack of accountability in South African municipalities.

- Description: Er3+-Yb3+ co-doped Ba5(PO4)3OH nanoparticle powder phosphors were successfully synthesized by urea combustion method. The resulting powder phosphors were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), high resolution scanning electron microscopy (HRSEM), energy dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS) and photoluminescence spectroscopy (PL). XRD data confirmed crystallization of pure hexagonal phase of Ba5(PO4)3OH and HRSEM images showed formation of ellipsoidal particles. XPS data combined with EDS analysis confirmed the materials composition that corresponds with identification of all the chemical elements constituting the materials. The in vitro dark cytotoxicity of the particles confirmed lack of cytocidal behaviour in the absence of light, but considerable photodynamic therapy (PDT) activity was observed upon illumination. Upon excitation using a 980 nm laser, multiple emission peaks in the green and red regions corresponding to the optical transitions of Er3+ ion were observed. Upon co-doping with Yb3+, upconverted red emission was detected and this was attributable to non-radiative energy transfer from Yb3+ to Er3+. The proposed mechanism of upconversion photoluminescence is discussed.

- Description: The preparation for the construction of the Square Kilometre Array, and the introduction of its operational precursors, such as LOFAR and MeerKAT, mark the beginning of an exciting era for astronomy. Impressive new data containing valuable science just waiting for discovery is already being generated, and these devices will produce far more data than has ever been collected before. However, with every new data instrument, the data rates grow to unprecedented quantities of data, requiring novel new data-processing tools. In addition, creating science grade data from the raw data still requires significant expert knowledge for processing this data. The software used is often developed by a scientist who lacks proper training in software development skills, resulting in the software not progressing beyond a prototype stage in quality. In the first chapter, we explore various organisational and technical approaches to address these issues by providing a historical overview of the development of radioastronomy pipelines since the inception of the field in the 1940s. In that, the steps required to create a radio image are investigated. We used the lessons-learned to identify patterns in the challenges experienced, and the solutions created to address these over the years. The second chapter describes the mathematical foundations that are essential for radio imaging. In the third chapter, we discuss the production of the KERN Linux distribution, which is a set of software packages containing most radio astronomy software currently in use. Considerable effort was put into making sure that the contained software installs appropriately, all items next to one other on the same system. Where required and possible, bugs and portability fixes were solved and reported with the upstream maintainers. The KERN project also has a website, and issue tracker, where users can report bugs and maintainers can coordinate the packaging effort and new releases. The software packages can be used inside Docker and Singularity containers, enabling the installation of these packages on a wide variety of platforms. In the fourth and fifth chapters, we discuss methods and frameworks for combining the available data reduction tools into recomposable pipelines and introduce the Kliko specification and software. This framework was created to enable end-user astronomers to chain and containerise operations of software in KERN packages. Next, we discuss the Common Workflow Language (CommonWL), a similar but more advanced and mature pipeline framework invented by bio-informatics scientists. CommonWL is supported by a wide range of tools already; among other schedulers, visualisers and editors. Consequently, when a pipeline is made with CommonWL, it can be deployed and manipulated with a wide range of tools. In the final chapter, we attempt something unconventional, applying a generative adversarial network based on deep learning techniques to perform the task of sky brightness reconstruction. Since deep learning methods often require a large number of training samples, we constructed a CommonWL simulation pipeline for creating dirty images and corresponding sky models. This simulated dataset has been made publicly available as the ASTRODECONV2019 dataset. It is shown that this method is useful to perform the restoration and matches the performance of a single clean cycle. In addition, we incorporated domain knowledge by adding the point spread function to the network and by utilising a custom loss function during training. Although it was not possible to improve the cleaning performance of commonly used existing tools, the computational time performance of the approach looks very promising. We suggest that a smaller scope should be the starting point for further studies and optimising of the training of the neural network could produce the desired results.

- Description: Background: Here, we report an atypical HIV-vacuolar myelopathy and search the available medical literature about atypical presentations of human immunodefciency virus associate vacuolar myelopathy (HIV-VM) and immunoglobu‑ lin therapy response. Case: A 26-year-old lady who was 4 weeks postpartum presented to us with acute faccid quadriparesis, with no sen‑ sory level. Extensive workup ruled out other causes of myelopathy. She developed a stage 3 acute kidney injury, and MRI showed difuse cord atrophy involving the lower cervical and thoracic cord. The patient received IV-immunoglob‑ ulin, ARVs, and supportive therapy with inadequate response. Unfortunately, she developed nosocomial pneumonia and died. Discussion: In HIV-VM, there is spinal cord atrophy, which mainly involves the thoracic cord. In our case, this patho‑ logical process also afected the spinal cord’s cervical region, leading to faccid tetraplegia, with high CD4 level, with‑ out response to the treatment, including intravenous immunoglobulin. Keynotes: Vacuolar myelopathy, HIV, Immunoglobulin therapy, faccid tetraplegia, hypokalaemia. Renal failure. Keywords: Human immunodefciency virus, Associated lesions of the nervous system, Human immunodefciency virus-associated myelopathy, Intravenous immunoglobulin administration, Case report, HIV-vacuolar myelopathy

- Description: Postgraduate education has grown enormously worldwide, which has led to supervisors being expected to take on a supervisor's role immediately upon graduation. But crossing the border from being a doctoral candidate to becoming a doctoral supervisor entails significant shifts in identity and an understanding of postgraduate pedagogy and institutional expectations. This paper argues that supervision development opportunities are crucial, but they need to be contextualised and include critical key agents with some institutional authority if they are to be deemed worthwhile and effect change. An online survey completed by 186 participants from across institutional types and disciplines in South Africa is analysed using Archer's social realism to provide insights into how emerging supervisors are currently supported. The resultant recommendations on supervision development could contribute to more confident border crossing by emerging supervisors.
