Verstedeliking in Bophuthatswana

The vesting pattern of the population of Bophutharswana is something special: the population shows a strong tendency to live in groups, and single-family homes are virtually unprecedented. But the settlements in which the groups occur are not at all homogeneous in nature or function.*This article is written in Afrikaans

Morality as the substructure of social justice: religion in education as a case in point

Moral issues and principles do not only emerge in cases of conflict among, for instance, religious communities or political parties; indeed they form the moral substructure of notions of social justice. During periods of conflict each opponent claims justice for his/her side and bases the claim on certain principles. In this article, reference is made to the differences among South Africans about the extent to which religion and religious differences in the population should be accommodated in public school education. Explorative hermeneutic phenomenology facilitates an investigation into the nexus between social justice and its moral substructure. This is followed by a discussion of the moral dilemma facing education policymakers regarding the accommodation of religion in public education, with the aid of two contrasting metaphors, namely, the Strict Father and the Nurturant Parent.Keywords: cycles of socialisation; morality; morality and religion; moral reasoning; morals; social justic

Towards understanding (religious) (in)tolerance in education

In recent years, schools and education authorities world wide have been paying increasing attention to issues surrounding diversity and religious (in)tolerance. The term ‘tolerance’ is, however, clouded by considerable confusion and vagueness. This article seeks to contribute to recent scholarly attempts at understanding (religious) tolerance and the term that denotesit. After a brief semantic analysis of the term ‘tolerance’, arguments  concerning the onticity of tolerance as phenomenon or entity are discussed. By examining its onticity we explore and explain some of the essential features of tolerance. The article ends with a brief discussion of some of the  implications of our examination that we foresee for (religion) education

Social justice praxis in education: Towards sustainable management strategies

Social justice, defined as an impetus towards a socially just educational world, is based on the assumption that all people, irrespective of belief or societal position, are entitled to be treated according to the values of human rights, human dignity and equality. Diverging from the classical positivist approach in social science research that takes injustice as its impetus, the researchers departed from a socio-rationalist approach into exploring sustainable management strategies for effective social justice praxis. This approach has enabled the construction of a conceptual-theoretical framework and an iterative qualitative inquiry, which has as its central principal the sustainable management strategies for effective social justice praxis. Four key findings affirmed the belief that good praxis was to be found in Gemeinschaft relationships, in the influence exerted by government and education systems and structures, where government and principals were found to be co-responsible in ensuring that the best interest of the child was served. This responsibility included practices found in collaborative efforts, where communities became the guardians of their schools due to a disciplined school that followed constitutional values. Lastly, these practitioners aligned their management strategies with human rights values, as well as human dignity and equality, and their strategies found pride of place in extant ubuntu principles.Keywords: determinants; education; human rights; management strategies; restorative; social justice praxis; sustainable development; transformative; ubunt

Intraocular lenses in age-related macular degeneration

Purpose: The aim of this work is to review the lenses, assessing their advantages and disadvantages. We describe a total of seven types of intraocular lenses (IOLs) recommended for age-related macular degeneration (AMD). Methods: We used the PubMed web platform to search for implantable devices in various stages of AMD. We searched for both prospective and retrospective studies and also case reports. Results: Clinical results in AMD patients have been described for a total of seven types of IOLs recommended for AMD: an implantable miniature telescope (IMT), IOL-VIP System, Lipshitz macular implant (LMI), sulcus-implanted Lipshitz macular implant, LMI-SI, Fresnel Prism Intraocular Lens, iolAMD and Scharioth Macula Lens. Conclusions: We conclude that to objectively ascertain the effectiveness and safety of these lenses, further independent clinical studies with longer follow-up data are necessary prior to the general use of these optical devices

Biological decolorization of xanthene dyes by anaerobic granular biomass

Biodegradation of a xanthene dyes was investigated for the first time using anaerobic granular sludge. On a first screening, biomass was able to decolorize, at different extents, six azo dye solutions: acid orange 7, direct black 19, direct blue 71, mordant yellow 10, reactive red 2 and reactive red 120 and two xanthene dyes—Erythrosine B and Eosin Y. Biomass concentration, type of electron donor, induction of biomass with dye and mediation with activated carbon (AC) were variables studied for Erythrosine B (Ery) as model dye. Maximum color removal efficiency was achieved with 4.71 g VSS L−1, while the process rates were independent of the biomass concentration above 1.89 g VSS L−1. No considerable effects were observed when different substrates were used as electron donors (VFA, glucose or lactose). Addition of Ery in the incubation period of biomass led to a fivefold increase of the decolorization rate. The rate of Ery decolorization almost duplicated in the presence of commercial AC (0.1 g L−1 AC0). Using different modified AC samples (from the treatment of AC0), a threefold higher rate was obtained with the most basic one, \textAC\textH2ACH2, as compared with non-mediated reaction. Higher rates were obtained at pH 6.0. Chemical reduction using Na2S confirmed the recalcitrant nature of this dye. The results attest that decolorization of Ery is essentially due to enzymatic and adsorption phenomena.This work was supported by the PTDC/AMB/69335/2006 project grants (Fundacao para a Ciencia e Technologia, FCT, Portugal), BRAIN project (ID 6681, European Social Found and Romanian Government and the grant of the Romanian National Authority for Scientific Research, CNCS-UEFISCDI, project number PN-II-ID-PCE-2011-3-0559, Contract 265/2011

Global patient outcomes after elective surgery: prospective cohort study in 27 low-, middle- and high-income countries.

BACKGROUND: As global initiatives increase patient access to surgical treatments, there remains a need to understand the adverse effects of surgery and define appropriate levels of perioperative care. METHODS: We designed a prospective international 7-day cohort study of outcomes following elective adult inpatient surgery in 27 countries. The primary outcome was in-hospital complications. Secondary outcomes were death following a complication (failure to rescue) and death in hospital. Process measures were admission to critical care immediately after surgery or to treat a complication and duration of hospital stay. A single definition of critical care was used for all countries. RESULTS: A total of 474 hospitals in 19 high-, 7 middle- and 1 low-income country were included in the primary analysis. Data included 44 814 patients with a median hospital stay of 4 (range 2-7) days. A total of 7508 patients (16.8%) developed one or more postoperative complication and 207 died (0.5%). The overall mortality among patients who developed complications was 2.8%. Mortality following complications ranged from 2.4% for pulmonary embolism to 43.9% for cardiac arrest. A total of 4360 (9.7%) patients were admitted to a critical care unit as routine immediately after surgery, of whom 2198 (50.4%) developed a complication, with 105 (2.4%) deaths. A total of 1233 patients (16.4%) were admitted to a critical care unit to treat complications, with 119 (9.7%) deaths. Despite lower baseline risk, outcomes were similar in low- and middle-income compared with high-income countries. CONCLUSIONS: Poor patient outcomes are common after inpatient surgery. Global initiatives to increase access to surgical treatments should also address the need for safe perioperative care. STUDY REGISTRATION: ISRCTN5181700

Empowering Academics the Viskerian Way

Academics and/or scholars increasingly feel that their academic voice (combined or individual) has been squelched by the demands of performativity in its various guises, and resultantly, that they have been caught up in a process of steady disempowerment. Rather, it should be their right to be free to use their positions in the pursuit of scholarship as their conscience and their expert knowledge of their subject dictate. Academics should be free to question for themselves the boundaries of their limitations, and not have these i mposedon them by the state or government bureaucracy. In order to help empower academics to regain their academic voice and identity, this article transposes six of the philosophical ideas of Belgian philosopher Rudi Visker to the world of academia. It explores the possibilities of using these ideas as instruments for the promotion and maintenance of academic freedom.Key concepts: academic freedom, managerialism, institutions of higherlearning, Rudi Viske
