Description: The international collaboration of the Square Kilometre Array (SKA), which is one of the largest and most challenging science projects of the 21st century, will bring a revolution in radio astronomy in terms of sensitivity and resolution. The recent launch of several new radio instruments, combined with the subsequent developments in calibration and imaging techniques, has dramatically advanced this field over the past few years, thus enhancing our knowledge of the radio universe. Various SKA pathfinders around the world have been developed (and more are planned for construction) that have laid down a firm foundation for the SKA in terms of science while additionally giving insight into the technological requirements required for the projected data outputs to become manageable. South Africa has recently built the new MeerKAT telescope, which is a SKA precursor forming an integral part of SKA-mid component. The MeerKAT instrument has unprecedented sensitivity that can cater for the required science goals of the current and future SKA era. It is noticeable from MeerKAT and other precursors that the data produced by these instruments are significantly challenging to calibrate and image. Calibration-related artefacts intrinsic to bright sources are of major concern since, they limit the Dynamic Range (DR) and image fidelity of the resulting images and cause flux suppression of extended sources. Diffuse radio sources from galaxy clusters in the form of halos, relics and most recently bridges on the Mpc scale, because of their diffuse nature combined with wide field of view (FoV) observations, make them particularly good candidates for testing the different approaches of calibration. , Thesis (MSc) -- Faculty of Science, Physics and Electronics, 2022

Description: Manual lifting is dynamic in nature and involves asymmetrical loading of the human body. This study investigated kinematic and kinetic characteristics of asymmetrical lifting in three dimensions, and then constructed a 3-D biomechanical force model of the lower back which is capable of quantifying torsional stress on the human spine. Eleven healthy adult male manual workers were recruited as subjects and lifted a 1 Okg load placed at the sagittal plane (0°) and at 30°, 60° and 90° lateral planes to the right, from 150mm and 500mm initial lift heights, respectively, to an 800mm high bench in the sagittal plane. Subjects' spinal motions and the trajectorial movements of the load in three-dimensional space were monitored simultaneously by a Lumbar Motion Monitor and a V-scope Motion Analyzer. Generally, the spinal motion factors increased as a function of increasing task asymmetry and differed (p < 0.05) between the lower (150mm) and higher (500mm) levels in the sagittal plane. In all asymmetrical conditions the motion factors showed a dramatic increase at the 500mm level compared to the increase at the 150mm level. The rates of increase in the horizontal and frontal planes were greater than those in the sagittal plane. Task asymmetry had a significant effect on the spinal kinematic parameters in the frontal plane at the two lift heights, and only at the high level (500mm) in the horizontal plane, with exception of average acceleration . Initial lift height exerted a significant effect on peak velocity and acceleration in both frontal and horizontal planes and on range of motion in the horizontal plane. Kinetic characteristics of the object being lifted in three-dimensions increased with an increase in task asymmetry. The increase was more dramatic in the lateral direction in the horizontal plane. However, motion factors in the vertical direction dominated the full range of the lift, irrespective of task asymmetry and lift height. The kinetic measures differed (p < 0.05) between the lower ( 1 50mm) and the higher (500mm) levels in the vertical direction except for average force. Task asymmetry had a significant effect on dynamic measures in the anterior-posterior direction. Both task asymmetry and lift height had a significant effect on dynamic motion factors in the lateral direction. From insights gained in the empirical study a three-dimensional biomechanical force model of the lower back was constructed based on a mechanism of muscle force re-orientation in the lumbar region. Acknowledging that the lower back is designed to be able to rotate around its longitudinal axis, the proposed model accounts for compression and shear forces and a torsional moment. The model has similar predictability to Schultz and Andersson's (1981) model when the human trunk exerts only a flexion-extension moment in the sagittal plane, but additionally predicts dramatic increases in shear forces, oblique muscle forces and torsional moment under asymmetrical lifting conditions which the Schultz-Andersson model does not. The increase rates in these forces and moment are not linearly related over task asymmetric angle.

Description: Among the Xhosas, the healing sickness called intwaso is interptreted as a call by the ancestors to become a healer. Transpersonalists also see these initiatory illnesses as spiritual crises, while according to the widely accepted Western psychiatric view, illness is purely perceived in physical and psychological terms. A case study was conducted where a single participant who has undergone the process of ukuthwasa and is functioning as a traditional healer was interviewed. A series of interviews were done where information was gathered about significant experiences related to ukuthwasa process. Tapes were transcribed and a case narrative was written and interpreted using the traditional Xhosa beliefs, the western psychiatric and the transpersonal psychology perspectives. Strengths and weaknesses of each perspective were then examined.

Description: Mental health care in South Africa has long been governed by inequalities (Foster & Swartz, 1997). During apartheid, those who did not speak English and Afrikaans could not access mental health services in the same way as those who did (Foster & Swartz, 1997). One main reason for this is the majority of mental health practitioners could not, and were not required to speak languages other than English and Afrikaans (Swartz, 1991). The South African mental health literature suggests that language and communication must be prioritised if there is to be an improvement in mental health care services for those individuals who do not speak English and Afrikaans (Bantjes, 1999; Drennan & Swartz, 1999; Swartz & Drennan, 2000; Swartz & MacGregor, 2002). Drawing on Prasad's (2002) interpretation of Gadamer's critical hermeneutic theory and utilising thematic networks analysis (Attride-Stirling, 2001), this study investigated the process of translated clinical assessment interviews within a psychiatric hospital in the Eastern Cape Province within South Africa. Results of the study revealed that contextual factors, issues concerning linguistic and cultural heritage, clinicians' role expectations regarding translators' role performance, as well as relational dynamics regarding individual levels of control and influence within the translation triad, all impacted on the effectiveness of communication, translation and service provision. These fmdings are supported by literature on the theory and practice of translation that identifies these issues as prominent (Robinson, 2003). Specific recommendations regarding the formalisation of translation practices within the hospital setting, as well as the familiari~ation of clinical practitioners and psychiatric nurses with the intricacies of translation processes are offered.

Description: The following paper aims to analyse lines 660 – 774 of Euripides’ Bacchae paying close attention to the representation of the bacchants in the account given to Pentheus by the herdsman.1 Accompanying the translation is a brief commentary further elaborated and discussed in the paper below. The purpose of this paper is to investigate how the Theban women are portrayed in the hills outside of Thebes and the implications this might for the inherent conception of the supposed structure of the polis and the oikos. Dionysos’ arrival in Thebes hails a systematic disruption of the social order of the Theban polis. His presence causes an inverting of all that is familiar to the Thebans, the unknown becomes known and the known reveals itself as unknown. Euripides’ Bacchae was first performed at the City Dionysia in 405 BCE, in the year after the tragedian’s death. The play dramatises the arrival of the god Dionysos to Thebes to exact vengeance on those responsible for his mother’s death and to establish his mysteries there (line 24f & 47f). Before one can begin any analysis of the text, it is important to establish the context established by the play, as this context is important to a fuller understanding of the text. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2021

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

Description: My study explores the politics of viewing and the gaze. I argue that the gaze both arrests and objectifies the body, which in turn transforms subjects into objects therefore regulating social behaviour. The basic notion of the gaze will be explored throughout this thesis and thereby contextualizes my sculptures, which are casts of my naked body. My particular concern lies in how the ideas of surveillance have had an influence on architecture and buildings in Grahamstown. Throughout this mini thesis, I will explore a number of architectural spaces of Grahamstown such as the Provost prison, Fort Selwyn and the Camera Obscura which I argue were all designed based on the ideas of surveillance. The entanglement of Grahamstown architecture and the female form as a subject of voyeurism forms an important part of this thesis, as the context of Grahamstown architecture is centered on visibility, which in turn subjects people to a form of discipline. The Provost Prison, the Camera Obscura and the forts of Grahamstown are all good examples of this. Outside of this, the female body is also subjected to the gaze, which in turn suggests that the female body is also under surveillance and as a result also becomes disciplined. My installation is a response to Antony Gormley’s Event Horizon, in which he placed 33 steel and fibreglass casts of his own naked body at an elevated level on buildings around Manhattan and Brazil. In this discussion I have contextualized my work with reference to the ideas of different theorists. The three main theorists I have cited are Michel Foucault, Jonathan Crary and Laura Mulvey. Foucault is specifically cited due to his discussion on Panoptic power, surveillance and docile bodies. Crary makes a number of important points with regards to the ideological operations of the Camera Obscura as well as its history while Laura Mulvey’s writings form the basis of the voyeuristic gaze from the perspective of a feminist.

Tidal exchanges of carbon, nitrogen and phosphorus between a Sarcocornia salt-marsh and the Kariega estuary, and the role of salt-marsh brachyura in this transfer

Description: Tidal exchanges of organic carbon, nitrogen and phosphorus between a south temperate Sarcocornia marsh and its associated estuary are examined. Subterranean water flow was small, and the hydraulic exchange between the two systems largely surficial. The dominant tidal signal was semi-diurnal, and the extent of inundation of the marsh varied considerably as a consequence of interactions of semi-lunar tidal cycles with changes in daily mean sea level. Annual net fluxes of organic carbon were directed from the marsh to the estuary, but amounted to less than 2% of marsh aerial net primary productivity. This indicates the incompatibility of E.P. Odum's outwelling hypothesis to this marsh-estuarine system. The direction of net flux of organic carbon switched on a time-scale of days. These directions were largely correlated with mesoscale oceanic events, which materially altered the extent of marsh inundation, and which provided evidence of the mutual exclusivity of outwelling of DOC from the marsh and oceanic upwelling. Laboratory mesocosm experiments using intact marsh blocks of sediment from the marsh were conducted to identify the proximate processes and interactions at the marsh-water interface responsible for the variability of marsh-estuarine exchanges. Patterns of fluxes of organic carbon, total nitrogen and phosphorus were markedly different in the structurally contrasted tidal creek and Sarcocornia Zone regions of the marsh. Both regions exported these components, but the fluxes of organic carbon and total phosphorus were significantly larger from the tidal creek than from the Sarcocornia zone, and the opposite applied to nitrogen. The presence of brachyuran crabs . the most numerous macrofauna on the marsh enhanced the flux of carbon, nitrogen and phosphorus from the marsh biocoenosis, largely as a result of the effect of their bioturbation. Evidence is examined which suggests that differential mobilization of nutrients in the two zones by crabs is responsible for biogeochemical coupling of these two regions , which may account for the elevated productivity of salt- marsh systems

Description: This study analysed the representation of the Millennium Development Goals (MDGs) in the Mail and Guardian from 2000 to 2007. It drew on perspectives from cultural studies, the constructionist approach to representation and the sociology of news production. Through the use of the quantitative and qualitative research methods, content analysis and critical discourse analysis, this study established first, that few significant changes have occurred within the newspaper's coverage of the MDGs during this period, and second, that the people most affected by the MDGs and affiliated programmes are seriously under-represented and that the manner of representation marginalises and subordinates them.

Description: It has not been my aim to provide conclusive evidence for or against anyone hypothesis regarding Time and Tense. I have simply attempted to collect together and collate much of what has been written on the topic of tense in English, in order to show what the current trends of thought are. In Chapter One I presented a brief survey of some of the more basic notions associated with time and tense, in order to provide a background for the more linguistic approach to follow. I therefore examined such issues as the difference between time and tense, the problem of the passage and directionality of time, of the present moment, time and space , tense as a universal, "and various features of tense systems. I sketched Bull's system of scalars, vectors and axes as representative of our English tense system. Chapter Two dealt with time and logic, but as I am a mere layman in matters logical, I refrained from discussing any individual logical system in depth, and rather discussed various problems which appear to confront the logician in formulating a tensed or tenseless logic. This chapter aimed at providing a better understanding of the linguistic issues to follow, for time and logic are intimately connected with language. Chapter Three was more linguistically oriented, and in it I attempted to provide a broad outline of the development of thoughts about tense before the Transformationalist period (pre 1960). Because of the vast scope involved, I had, perforce, to be brief at times. I gave attention to tense in classical grammatical studies, and summarized how it was seen from about 1500 to 1800. I gave more detailed treatment to the twentieth century, focussing specifically on grammarians like Jespersen (1933), Twaddell (1960), Ota (1963), Palmer (1965) and others - all, writers typical of the structuralist era. At the end of Chapter Three I provided an overall summary of ideas on the main tenses by the end of the structuralist period - ideas which were to change radically within the next few years. In Chapter Four I discussed the ideas of tense of some of the main transformationalist/generativists - Diver (1964), Crystal (1966), Huddlestone (1968), Gallagher (1970), McCawley (1971) and Seuren (1974), in an attempt to show how theories on tense were becoming increasingly abstract, and how most data indicated that it is highly probable that tense is an abstract higher predicate of the sentence in which it appears in surface structure, closely related to temporal adverbs. Chapter Five continued in the same vein. I tried to show, using syntactic tests, that tense is a higher predicate, and used arguments involving Conjunction Reduction (based on Kiparsky (1968)), VP Constituency, Sequence of Tense, Pronominalization, and Quantification. In Chapter Six I focussed more closely on tense-time adverbials, in order to show that they have the same syntactic properties as tense, are also probably deep superordinate predicates, and are closely related to tense. My suggestion was that either tense is derived from temporal adverbs or vice versa, as this would simplify the grammar. The derivation procedures at the end of the chapter (6.8) were largely based on Hausmann (1971). I made no detailed reference to extralinguistic matters which affect tenses, in this study - such factors as are diScussed by G. Lakoff (1971) (presuppositions and relative well-formedness) and by R. Lakoff (1975). Tense is not a matter of pure Structuralism, just as language is not - extralinguistic factors ought to be accounted for before any study can claim to be conclusive. For this reason I do not in any way claim to have made an exhaustive study of time and tense - I have simply attempted to summarize and coordinate thoughts on the subject, and to suggest tentatively that the most adequate grammar of English would probably derive tense from underlying temporal adverbs.

Description: Suboptimal preparation for the Ironman triathlon can have detrimental effects on mental and physical condition. The purpose of this longitudinal investigation was to examine the relationship between a number of performance changes and fatigue markers during training for an Ironman as well as immediately after the event, in an attempt to better understand the effects of ultraendurance training. Eighteen athletes training for the Ironman; South Africa, 2009 were recruited for the study. Over the 6 month data collection period body mass, training load (TRIMP and Session x RPE methods), physiological responses (waking heart rate, postural dizziness, sleep ratings), changes in psychological state (profile of mood states - POMS), reported immunological responses (symptoms of illness), biochemical changes (salivary cortisol and alpha amylase) and performance (8 km submaximal running time trial (TT) and race day performance) were measured. These responses were compared to a control sample (n=15). Results show a significant increase (p<0.05) in training load (3899.4 ± 2517.8) four weeks prior to the event. Fatigue scores significantly increased (p<0.05) concurrently with this significant increase (p<0.05) in training. TT performance did not significantly (p<0.05) alter during the time course of training. It was however strongly correlated to training load (R2=0.85) and modestly related to race performance (R2=0.65). The signs and symptoms of upper respiratory tract infections (URTI) were prevalent during the training period, decreasing during the taper and race period. Large standard deviations were found within the majority of the responses. During the final two weeks of preparation, tension scores were significantly increased (p<0.05) while training load significantly decreased (p<0.05) during the final week of preparation. Cortisol increased significantly (p<0.05) immediately post race (0.507±0.15

Description: Background: Accurate and reliable in-game data is fundamental when designing effective batting training. A simulated batting protocol that could aid research and training has not been specifically designed for female cricketers because of a distinct lack of empirical in-game data for the women’s version of the game. Objective: The purpose of this study was to quantify the motion demands and run-breakdown of a century and T20 half-century for women’s cricket matches to establish a simulated batting protocol specifically designed for female batters. Method: Time-motion analyses of four one-day international and six T20 innings were conducted on international cricket matches played around the world between 2012 and 2017. The innings was divided into the bowling and batting innings. The ODI innings that met the criterion of 100 runs scored and T20 innings with scores above 50 runs were used in the run breakdown, which included scores from the top 10 countries ranked by the ICC. The time-motion analyses and century breakdown were utilised in the establishment of a simulated batting protocol. The simulated batting protocol for female batters was created/developed by utilising the method designed by Houghton et al., (2011), who developed the BATEX© protocol. Results: The time-motion analyses indicated that the mean duration of an ODI innings was 169 minutes. An over lasted 2.45 minutes, with 24.86 seconds between each delivery and 55 seconds between each over. When the bowling side changed to a new bowler, it was 1.12 minutes between overs. The mean score for the first power play in an ODI was 41 runs with 1.38 wickets being taken. The mean score during the second power play was 28 runs with 0.714 wickets being taken. The T20 bowling innings lasted 75.50 minutes, with an over lasting 2.52 minutes with 25.58 seconds between deliveries. The mean score in the T20 batting innings was 122 runs. During the power play, which lasted 24.35 minutes, 37 runs were scored with 1.45 wickets being taken. The simulated batting innings was then designed as four stages lasting the duration of a typical women’s century. Each stage was based on theoretical phases of play that may occur during a batting innings. Conclusion: The study indicated that the women’s game has different movement requirements compared to the men’s game in both the ODI and T20 formats. Further, the demands differ depending on the country that is playing. A training and research protocol specifically designed for female batters is an important outcome.

Description: Galaxy kinematics is of crucial importance to understanding the structure, formation and evolution of galaxies. The studies of mass distributions giving rise to the missing mass problem, first raised by Zwicky (1933), give us an insight into dark matter distributions which are tightly linked to cosmology. Neutral hydrogen (H i) has been widely used as a tracer in the kinematic studies of galaxies. The Square Kilometre Array (SKA) and its precursors will produce large Hi datasets which will require kinematic modelling tools to extract kinematic parameters such as rotation curves. TiRiFiC (Józsa et al., 2007) is an example of such a tool for 3D kinematic modelling of resolved spectroscopic observations of rotating disks in terms of the tilted-ring model with varying complexities. TiRiFiC can be used to model a large number (20+) of parameters which are set in a configuration file (.def) for its execution. However, manually editing these parameters in a text editor is uncomfortable. In this work, we present TiRiFiG, Tilted Ring Fitting GUI, which is the graphical user interface that provides an easy way for parameter inputs to be modified in an interactive manner.

Description: In an effort to move away from Apartheid and its evils -South Africa and South Africans have committed to a shared moral project -the Rainbow Nation-Building Project (RNP); a project that confers certain moral duties and responsibilities upon its citizens, including a joint commitment to robust inclusivity, equality, and unity. Importantly, however, our environments –be they physical, social, or psychological –are such that they (actively or passively) obscure our awareness of some morally relevant facts about our society, and thereby hinder us as moral agents and therefore threaten our abilities to fulfil our moral project and commitment.What does it mean for us -a society ostensibly committed to the RNP -to be plagued by racism, sexism, queerphobia and xenophobia? What is it that contributes to our complicity regarding social practices and ideas that we would otherwise find morally objectionable? What does it say about our commitment to our publicly-exalted ideals and values (of inclusivity, diversity, reconciliation, justice, and unity) when we are unwittingly complicit in the marginalisation and social exclusion of members of our society? And how can institutions such as universities work to overcome this?In this work, I argue that the obscuring of, and failure to perceive, morally relevant facts that call on us for ethical attention and/or action -a phenomenon I refer to as ‘moral blindness’ -is responsible for at least some of our behaviours and practices that run contrary to our moral ambitions; and therefore has profound implications for us as moral agents and our ability to succeed in our moral goals. Moral blindness, then, is both an epistemic and ethical concern that enables socially unjust systems to perpetuate themselves; and is thus a threat toallmoral projects.I argue that, for South Africa, much of what can be identified as moral blindness is the direct result of the shifting and conflicting socio-cultural conditions the nation finds itself liminally caught amidst in its transition from its Apartheid past and towards its promised inclusive Rainbow Nation future. Commitment to the RNP, I argue, involves a self-transformation and habituation of certain supportive virtues on the part of South Africans to become the kinds of people who are compatible with the Rainbowist society -whom I call Rainbow Citizens. But this self-transformation itself is also a moral project, and therefore subject to the threat that moral blindness presents, and so too can be failed. If all this is true, then it seems that if we do not take moral blindness seriously, we could ultimately fail to become South African. , Thesis (MA) -- Faculty of Humanities, Philosophy, 2021
