  • Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 38 , Recent collecting in the Malawi lakes Chilwa and Chiuta has revealed a new haplochromine cichlid fish, Astatotilapia tweddlei, which is described and illustrated. It is distinguished from most members of this genus by an elongate, rounded caudal fin. Although having a distinctly different colour pattern and more slender pharyngeal bone, it shows a greater similarity to A. paludinosa, known only from the Malagarasi Swamp 1200 km to the north in the Zaire ichthyofaunal province, than it does to members of this genus from the closely adjacent Zambezi province from which this wetland system, in the East Coast province is separated by only some 50 km.

  • Description: The study investigates the effectiveness of humanitarian intervention as a strategy in conflict management in Africa drawing from case studies in Sudan and Libya. The research utilized an interaction of both primary and secondary data sources. Primary sources used are African Union (AU) official reports, United Nations Security Council (UNSC) official reports as well as official International Commission on Intervention and State Sovereignty (ICISS) reports. Secondary sources used include journal articles, newspapers, books and other online publications. Among others, the study found out that humanitarian intervention in Sudan by the AU from 2004 until 2006 lacked the capacity and political will to effectively manage the conflict. At the same time, an analysis of the North Atlantic Treaty Organization‟s (NATO) military intervention in Libya in 2011 reveals that western-led interventions in Africa are often driven by geostrategic interests rather than the need to save people in danger. Against this backdrop, the study recommends amongst others that the AU should have a capacitated standby-force that will rapidly respond to manage conflicts in Africa. Also, UN peacekeeping operations in Africa should be coordinated by the African Union. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2015

  • Description: Here the agreement between these two Ministers comes to an abrupt end. For while Dr. Koornhof says categorically that the only honourable way in which to do this, is by developing the resources of the homelands, Mr. Froneman states equally categorically that it is no part of the white man's duty to do so. Dr. Koornhof speaks of the moral and altruistic elements in the policy of separate development. Mr. Froneman speaks in the harshest and most callous terms of millions of "surplus" Africans, who must be sent back to their homelands, no matter what awaits them there. He says that African labourers in "white" areas must not be burdened with "superfluous appendages", such as wives, children, and dependents who could not provide service. These two men are in the same Cabinet. If one has been rebuked, it was done in private. And if it was done, it was no doubt done in a semi-jocular manner — "Fronnie, old boy, we all know what you mean, but you must learn to talk prettily." These two men do not represent two irreconcilable wings of the Nationalist Party, they represent the two essential elements of the policy of separate development. And these two elements are essential to each other. Either by itself would be dangerous. Either by itself would be unacceptable. Neither Mr. Froneman nor Dr. Koornhof has reached the stage when one cannot bear to be in the same Cabinet as the other. Although each of these two elements and each of these prototypes, is essential to the other, they do not co-exist in perfect harmony. The one is a naked baas, the other is a bass clothed in soft raiment. The first thinks the second is a sissy, the second thinks the first is a barbarian. They do not say so publicly, but their newspapers do, and that is not good. In the absence of any official pronouncement we must assume that they have been told that the sissy and the barbarian are essential to one another. The sissy will get the barbarian into nice company, the barbarian will protect the sissy if the nice company turns nasty. Why is it that although the barbarian and the sissy do not co-exist in harmony, they are (in spite of the dreams of rift-seekers) essential, the one to the other? Why do the callousness and the altruism not go to civil war? The answer is that neither of them is a fundamental. They are both imposed on something that is fundamental, and that is the preservation of white supremacy (which can be more gently called self-preservation, a soft word that turns wrath in some circles). Neither the callousness nor the altruism is part of the deep monolithic core. The cracks can show, the paint can peel, the fragments can flake off, but the core remains untouched. In times of ease (such as the present), one sees and hears and reads much of the cracking and the fragmentation. In times of danger (which will come), one is conscious of the monolithic core, which is like an ironwood heart in a softwood tree. If we accept the view that Mr. Froneman and Dr. Koornhof have something deep and fundamental in common, is there therefore nothing to choose between them? Or are Dr. Koornhof and his kind, bearers of hope for the future? For Mr. Froneman and his kind certainly are not. Their dream of the total separation of the races, if one chooses to dignfiy it by the use of such a term, is a dream which must be realised at whatever cost, and the cost will be the bitterness, and inevitably the hatred, of millions of Africans towards the white masters who make such heartless use of their power. It is claimed by our rulers that such bitterness does not exist except in the imaginations of sentimentalists and agitators, and it is true that the patience of Africans appears to be infinite. It takes a train disaster to strip the mask from the smiling face. Are Dr. Koornhof and his kind, bearers of hope for the future? Like Mr. Froneman, Dr. Koornhof believes in the policy of separate development. He does not attempt to conceal that this is to be done in the interests of self- preservation. If the homelands are developed, then more and more Africans will leave "white" South Africa to return to the places from which they were driven by the need for work, money, and food. Although Dr. Koornhof did not say so, it is justifiable to infer that he believes that white South Africa will be more secure if it sheds itself of its Africans, surplus or otherwise. There will be no competition in the labour market, no crime by rootless young black men in the beautiful white suburbs, and most important of all, no night of the long knife. But Dr. Koornhof wants this transformation to be made with justice. There must be work and food and hope in the homelands, and they must be helped to achieve autonomy, political and cultural and economic. It is the economic autonomy that poses the greatest difficulty. Even if it does not mean economic independence, it should mean a healthy economic relationship with "white" South Africa. This is where Mr. Froneman parts company with Dr. Koornhof. And this is where REALITY parts company with Dr. Koornhof too. The recognition that there can he no political and cultural autonomy unless there is at least a healthy relationship with “white” South Africa, is for REALITY a recognition by its political opponents that there are moral considera' tions which transcend those of naed self-preservation. These considerations were blue-printed (inadequately) by Professor Tomlinson in the ninteen- fifties, inexplicably ignored by Dr, Verwoerd (his biographer may one day explain why), and are now, in 1969, alternately honoured and dismissed by a two-tongued Cabinet. In any case REALITY rejects the Tomlinson or any other similar blueprint. The wealth of “white” South Africa was created by all of us jointly, and it belongs to all those who created is. , Journal includes vol. 1 no. 2 to vol. 1 no. 6 ; vol 2 no. 1 to vol. 2 no. 6 and vol. 3 no. 1 to vol. 3 no. 6 , Vol. 2 no. 3 is missing

  • Description: Obtaining informed consent is a great challenge in global health research. There is a need for tools that can screen for and improve potential research participants’ understanding of the research study at the time of recruitment. Limited empirical research has been conducted in low and middle income countries, evaluating informed consent processes in genomics research. We sought to investigate the quality of informed consent obtained in a South African psychiatric genomics study. A Xhosa language version of the University of California, San Diego Brief Assessment of Capacity to Consent Questionnaire (UBACC) was used to screen for capacity to consent and improve understanding through iterative learning in a sample of 528 Xhosa people with schizophrenia and 528 controls. We address two questions: firstly, whether research participants’ understanding of the research study improved through iterative learning; and secondly, what were predictors for better understanding of the research study at the initial screening? During screening 290 (55%) cases and 172 (33%) controls scored below the 14.5 cut-off for acceptable understanding of the research study elements, however after iterative learning only 38 (7%) cases and 13 (2.5%) controls continued to score below this cut-off. Significant variables associated with increased understanding of the consent included the psychiatric nurse recruiter conducting the consent screening, higher participant level of education, and being a control. The UBACC proved an effective tool to improve understanding of research study elements during consent, for both cases and controls. The tool holds utility for complex studies such as those involving genomics, where iterative learning can be used to make significant improvements in understanding of research study elements. The UBACC may be particularly important in groups with severe mental illness and lower education levels. Study recruiters play a significant role in managing the quality of the informed consent process.

  • Description: No formal study on the incidence and extent of medullated and coloured fibres has been performed in South Africa. The purpose of this research project was to investigate the validity of the claims that there has been an increase in the production of wool contaminated with medullated and coloured fibres. Therefore, the main aim of this study was to determine whether the incidence and extent of medullated and coloured fibres in the South African wool clip have changed over time. Secondly, the study aimed to determine whether the incidence and extent of medullated and coloured fibres have a distinct geographic distribution. This study explored eight years of wool production records (2010 to 2017) obtained from BKB, the largest wool broker in South Africa. For the purpose of this research, the wool-producing areas of South Africa were divided into 6 regions, according to average annual rainfall, vegetation type and major farming practices applied in the area. Statistical analysis of the data included descriptive statistics, analysis of variance and post-hoc tests, as well as regression analyses. This study succeeded in quantifying the extent and prevalence of contamination with medullated and coloured fibres in the South African wool clip. The overarching conclusions were: • Floating kemp is the most important contaminant of wool in South Africa, with the incidence of harsh kemp and coloured fibres being very low. • Generally, the most important areas that need attention in combatting contamination in the South African wool clip, are the Mixed Farming Summer Rainfall Region, the Semi-Arid Grassveld and the High Rainfall Grassland. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

  • Description: Point-of-care ultrasound (POCUS) is a fast-growing clinical utility and is becoming an essential clinical skill for all practitioners attending to critically ill patients. Ultrasound equipment is now smaller, more affordable and readily available in clinical work areas. POCUS is performed by a non-cardiologist physician at the patient’s bedside as an adjunct to the physical examination. It is easily taught, non-invasive and allows for real-time clinical information. Bedside use of ultrasound imaging aids with rapid diagnosis of severe and life-threatening pathological conditions. It can be repeated, may change clinical management, and impact on patient outcome. POCUS has a broad clinical use, including, but not limited to, focused assessed transthoracic echocardiography (FATE), lung ultrasound imaging, extended focused assessment with sonography for trauma (e-FAST), vascular access and regional blocks. It may also be extended to detect endotracheal intubation and the estimation of intracranial pressure. Assessment of cardiac pathology by POCUS, performed by a novice examiner, has been shown to compare with the gold standard of an expert. Training is paramount. The physician should know his limitations and always relate the information back to the clinical scenario and context. By incorporating POCUS as part of our armamentarium and into our daily medical practice, we might see it reach its full clinical potential, optimising patient care and improving patient outcomes.

  • Description: The photophysical properties of two newly synthesized phthalocyanines (Pcs) were studied in the presence and the absence of 3-mercaptopropionic acid (MPA) capped quantum dots (QDs). Energy transfer processes resulting from the combination of QDs and the Pcs: 4-(tetrakis-5-(trifluoromethyl)-2-mercaptopyridinephthalocyaninato)zinc(II) (TtfmMPyZnPc, 3) and 4-(tetrakis-5-(trifluoromethyl)-2-pyridyloxyphthalocyaninato) zinc(II) (TtfmPyZnPc, 4) were also studied. The photophysical properties of the Pcs in the presence of QDs were enhanced and Förster resonance energy transfer (FRET) was observed with the phthalocyanines used. The efficiency of FRET between the QDs and TtfmMPyZnPc and TtfmPyZnPc was found to be 0.31% and 0.45% in DMSO and 0.24% and 0.32% in pyridine, respectively. The triplet state quantum yields for TtfmMPyZnPc and TtfmPyZnPc were found to be 0.86 and 0.74 in DMSO and 0.83 and 0.76 in pyridine.

LCT in mixed-methods research: evolving an instrument for quantitative data

  • Description: publisher version , A mantra of social science declares a fundamental divide between the quantitative and the qualitative that involves more than methods. According to this depiction, the two methodologies are intrinsically associated with a range of ontological, epistemological, political and moral stances. Each of these constellations of stances is strongly integrated, such that choice of method is held to involve a series of associated choices. Each constellation is also strongly opposed to the other, along axes labelled positivism/constructivism, scientism/humanism, conservative/critical, old/new, among others. These ‘binary constellations’ (Maton 2014b: 148-70) offer a forced choice between two tightly-knit sets of practices that are portrayed as jointly exhaustive and mutually exclusive. So widespread is this methodological binarism that many scholars ‘are left with the impression that they have to pledge allegiance to one research school of thought or the other’ (Johnson and Onwuegbuzie 2004: 14). A competing mantra disclaims this divide. Distinctions underpinning the picture of binary constellations have been regularly dissolved. Arguments that one deals with numbers, the other with words, one studies behaviour, the other reveals meanings, one is hypothetico-deductive, the other inductive, one enables generalization, the other explores singular depth, among others, have been repeatedly undermined (e.g. Hammersley 1992). Indeed, the death of the divide is frequently declared. Calls for ‘transcending’ (Salomon 1991) or ‘getting over’ (Howe 1992) the quantitative-qualitative debate and arguments for mixed-methods research (Brannen 2005; Johnson and Onwuegbuzie 2004) are recurrent. These calls highlight how the methodologies offer complementary insights for research and demonstrate that eschewing either methodology on principle is unnecessarily renouncing potential explanatory power. However, the call to mixed-methods research remains more breached than honoured. Methodological monotheism remains dominant – studies of education and society typically adopt either quantitative or qualitative methods. As we shall discuss, the former is typically associated with the influence of psychology and the latter is often claimed as emblematic of sociology. Studies utilizing the sociological frameworks on which Legitimation Code Theory (LCT) builds have echoed this pattern by overwhelmingly adopting qualitative methods. Accordingly, Part I of this volume begins by exploring how LCT concepts can be enacted in qualitative research (Chapter 2). However, LCT is not limited to one methodology and a growing body of mixed-methods research is engaging with both qualitative and quantitative data. In this chapter we illustrate how this research works and the gains it offers. For resolutely qualitative researchers, the prospect of reading anything quantitative, even in mixed-methods research, may be unenticing. However, it would be a mistake to pass over this chapter, for several reasons. First, we offer insights into research practice that might surprise such scholars. As Bourdieu argued, ‘methodological indictments are too often no more than a disguised way of making a virtue out of necessity, of feigning to dismiss, to ignore in an active way, what one is ignorant of in fact’ (Bourdieu and Wacquant 1992: 226). Our aim is to contribute towards removing this reason for one-sidedness. We show, for example, how quantitative methods confound their common portrayal as neat, straightforward and procedural; they are complex and involved and require craft work and judgement. Our focus is, therefore, more practical than metaphysical. We shall not enter seemingly endless debates over whether the ‘quantitative-qualitative divide’ refers to paradigms, epistemologies or methods and whether these are complementary or incommensurable. Rather, we discuss the development of an instrument for enacting LCT concepts in quantitative methods and ground this account in real examples of mixed-methods research. Specifically, we trace the evolution of an instrument for embedding specialization codes within questionnaires through its creation for research into school music and then its development within studies of educational technology. Given that mathematics can be off-putting to the noviciate, we minimize discussion of statistics and explain measures in lay terms. Second, this is much more than a story of quantitative methods. The evolution of the instrument both shaped qualitative methods and was shaped by the data they generated, offering insights into how qualitative research can more fully engage with LCT. Its development also involved intimate dialogue with theory that shed fresh light on LCT itself, making explicit the ‘gaze’ embodied by the framework (Chapter 1, this volume). We shall highlight wider lessons learned about the craft of enacting LCT in research, lessons of direct relevance for studies using any methods. Third, we shall illustrate the explanatory power offered by using quantitative and qualitative methods together, such as providing a robust basis for detailed findings, identifying wider-scale trends typically inaccessible to qualitative methods that provide a context for their data, and facilitating knowledge-building through greater replicability across contexts and over time. For example, the technology studies built directly on the music studies to cumulatively develop the instrument and generated probably the largest data set in code sociology: 97,386 responses (83,937 student and 13,449 staff surveys) on the organizing principles of academic subjects, alongside 20 in-depth qualitative case studies of secondary schools. This offers a foundation of substantial breadth and depth for making claims about knowledge practices across the disciplinary map and a firm basis on which future research into disciplinary differences can build. Moreover, the quantitative instrument itself can be adopted or adapted in new studies, further enabling cumulative knowledge-building. Given these substantive, methodological and theoretical gains, it is perhaps surprising there exists any temptation to skip past discussion of mixed-methods research. This reflects the methodological character of the fields in which LCT emerged. We thus begin by briefly illustrating how the sociological frameworks on which the theory builds have become distanced from quantitative methods.

  • Description: Is crime fiction the new 'political novel' in South Africa? Why did the apartheid censors disapprove of crime fiction more than any other genre? Crime fiction continues to be a burgeoning literary category in post-apartheid South Africa, with more new authors, titles and themes emerging every year. This book is the first comprehensive survey of South African crime fiction. It provides an overview of this phenomenally successful literary category, and places it within its wider social and historical context. The authors specialise in both literary studies and print culture, and this combination informs a critical analysis and publishing history of South African crime fiction from the nineteenth century to the present day. The book provides a literary lineage while considering different genres and sub-genres, as well as specific themes such as gender and eco-criticism. The inclusion of a detailed bibliography of crime fiction since the 1890s makes A Survey of South African Crime Fiction an indispensable teaching and study aid

  • Description: South Africa enjoys strong policy support for the integration of environmental issues into school curricula. However, much doubt exists over the extent to which this has been converted into appropriate classroom practice at the majority of under-resourced rural schools in the country. This article reports on a study which piloted a research tool which can be used to analyse teachers’ lessons, with the aim of gaining insight into the extent to which they integrate natural resource management issues. The research tool was based on Bernstein’s concept of classification and consisted of five indicators of natural resource management integration into Life Sciences lessons. The study contributes to the design of research tools that can be used to analyse and monitor the integration of environmental issues into teachers’ lessons. It also provides some insight into the environmental content of a sample of Grade 10 Life Sciences lessons at four rural underresourced schools in the Eastern Cape.

  • Description: Entrepreneurship plays an important role in societies around the world because it supports economic growth and creates job opportunities. This study investigated the nature of entrepreneurship in three distinct parts of Sakhisizwe Local Municipality, including a town within Sakhisizwe’s former homeland area, rural communities within its former homeland area, and a town within an area characterised by large-scale commercial farms. The study sought to establish the share of adults in the different parts of the municipality involved in entrepreneurship, to identify factors that contribute to the decision to become an entrepreneur, and to examine strategies pursued by, and challenges experienced, different types of entrepreneurs. The study involved a random sample of 362 respondents and both quantitative and qualitative data analysis. Among the main findings is that the proportion of adults involved in enterprise in Sakhisizwe is higher than found by other studies for South Africa as a whole, but is especially high for those living in the town in the former homeland area. While those residing in rural communities also engage in enterprise, they are generally compelled to practice their enterprises in town, thus have the disadvantage of needing frequent transport. While residing in the town in the commercial farming area is not disadvantageous in the same way, the challenge is that the town itself is able to support relatively few entrepreneurs due to fewer people coming to town for their shopping. , Thesis (MSci) -- Faculty of Science and Agricultures, 2022

H2 and Zn 5,10,15,20-tetrakis[4-(benzyloxy) phenyl] porphyrin were encapsulated onto binary micelle mixture of Pluronic F127/P123. The fluorescence and singlet oxygen generating behaviour of the porphyrins were investigated following incorporation. The fluorescence quantum yield for H2TBnOPP (ΦF = 0.034) was higher than that of ZnTBnOPP (ΦF = 0.023) and decreased when ZnTBnOPP or H2TBnOPP when in the presence of Pluronic F127/P123 binary mixtures. The kq values were 2.8 × 108 and 3.7 × 108 M−1 s−1, for H2TBnOPP + Pluronic F127/P123 and ZnTBnOPP + Pluronic F127/P123 in water, respectively. The binding constants (Kb) were 1.58 × 105 M−1 and 1.02 × 105 M−1 for ZnTBnOPP + Pluronic F127/P123 and H2TBnOPP + Pluronic F127/P123, respectively.

  • Description: The National Union of Mineworkers has asked for a meeting with the Minister to highlight the severe social and economic effects that are caused by the low rand gold price and the consequent rationalisation measures that are being implemented by the gold mines. The severity of the crisis is well illustrated by the case of the Harmony Gold Mine in the Orange Free State. This is the largest of the so-called "marginal" gold mines and last week it retrenched over 6 000 workers. The gold mines have cut back over 130 000 jobs over the last five years. The job cuts have speeded up again in 1992 as the gold price has continued at low levels. The NUM expressed its deep concern at this contraction in the gold industry most strongly at the Summit on the Future of the Mining Industry in June 1992. This meeting was attended by mining houses, the trade unions and several state departments. The NUM made a plea for a national plan and a national policy to regulate and manage the process of down-scaling. Despite the formation of a Summit Steering Committee to consider this and other proposals, and a whole series of working-group meetings involving all parties, nothing practical has come out of the process to address the issue of down-scaling.
