The secularisation theory of Max Weber states that modernisation inevitably leads to the decline of religion. This theory has in recent years been challenged by the desecularisation theories of various sociologists and philosophers. This article probes the possible link between modernisation and secularisation through a case study of the Republic of South Africa. South Africa is an important case study because it went through a rapid process of modernisation from the 1990s onwards. The first section examines the secularisation thesis of Weber and his supporters, as well as theories of desecularisation. The second section discusses the periods of anti-modernisation (1910–90) and modernisation (1990–2012) in South Africa. The third section analyses statistical data on the state of religion in South Africa, while the last section offers some concluding remarks on the relationship between modernisation and secularisation in South Africa thus far. The finding of the article is that the South African experience indicates that modernisation has an impact on religion, but the effect is not necessarily one of a decline in religion. In South Africa, modernisation has led to the decline of religion in some communities and the rejuvenation of religion in others. The effect of modernisation on religion seems to depend on its interaction with a range of other social factors.

Amid a global cultural landscape defined both by the ambiguities of deterritorialization and the persistent impact of established geopolitical hierarchies, the idea of cultural reflux offers a potent tool to conceptualize and lend context to the study of nascent peripheral and semiperipheral media industries. Dialoguing with Thussu and Iwabuchi’s work on media flow as well as Curtin’s concept of media capitals, this article proposes to analyze “mockbusters”: derivative copies of established metropolitan media properties. I specifically look at the output of the Brazilian studio Video Brinquedo, infamous in the 2000s for its blatant, low-quality copies of established children’s media properties. In examining the BRICS (Brazil, Russia, India, China, and South Africa) mockbuster as a case study of opportunistic media counterflow, the idea of cultural reflux complicates debates over where we should situate our analytical objectives with respect to mediatic peripherality, and how we can more concretely examine the relationship of media flow to transnational imperial frameworks.

Investors and collectors hold gold as protection for their savings and wealth atlarge. Gold does not pay interest like treasure bonds or savings accounts, but current goldprices often reflect increases and decreases of an asset. This research aims to provide amodel for the relationship between the exchange rate, which is vital in exporting gold, andgold prices across countries. The Australia, Brazil, and South Africa exchange rates areused as a case study against the gold price. The ARIMA model is used for forecasting goldprice as an input for the Transfer Function and VARIX models. The Transfer Functionmodel only considers the relationship between gold prices as input with the exchange ratein each country, whereas the VARIX model also considers the interrelationship betweenexchange rates in these countries. Daily data is used for the period 1st June 2010 to the28th February 2018. The RMSE and MAPE are used as criteria for selecting the bestmodel. The results show that VARIX is the best model for forecasting the Australianexchange rate, while the Transfer function is the best model for forecasting South Africanand Brazilian exchange rates.

Abstract The Kheis Province is situated between the Namaqua-Natal Province and the western margin of the Kaapvaal Craton in the Northern Cape Province of South Africa. It has been described as a thin-skinned fold and thrust belt formed between 1800 and 1700 Ma. The lithostratigraphic subdivision of the rock units comprising the Kheis Province has been a source of much controversy. From detailed study of aerial photography and satellite imagery, as well as field-based studies, the outcrop patterns in the Kheis Province and Kaaien Terrane were reinterpreted and a new stratigraphic subdivision is outlined here. It is proposed that the structural Kaaien Terrane and Kheis Province should be combined into the Kheis Terrane and that the rocks occurring in the Kheis Terrane should be grouped together to form the new Keis supergroup, with the basal metaconglomerate of the Mapedi/Gamagara Formation recognised as the regional unconformity between the Keis supergroup and the underlying rocks of the Transvaal Supergroup in the Griqualand West area. The Keis supergroup is subdivided from the base upwards into the Elim-, Olifantshoek-, Groblershoop- and Wilgenhoutsdrif groups. The basal Elim group is composed of the Mapedi/Gamagara- and Lucknow formations. It is overlain with a regional erosional unconformity by the Olifantshoek group, which is made up of the Neylan-, Hartley-, Volop- and Top Dog formations. The Olifantshoek group is conformably overlain by the Groblershoop group which is comprised of three upward coarsening successions:the Faanshoek- and Faansgeluk formations,the Maraisdraai- and Vuilnek formations andthe Opwag- and Skurweberg formations. The Groblershoop group is in turn erosively overlain by the rocks of the Wilgenhoutsdrif Group, which include the basal erosive Groot Drink formation which is overlain by the Zonderhuis- and Leerkrans formations. The lithologies of the Keis supergroup are in faulted contact with the rocks of the younger Areachap Group of the ~1200 Ma Namaqua-Natal Metamorphic Province.

This paper studies the relationship between a firm’s boundary choices within its value chain and the BEE pressures it faces from its clients. The paper shows that BEE policy alters the value chain preferences of a firm’s clients. These changes in client preferences motivate the firm to altering its boundaries. More important, boundary changes due to BEE are implemented in a way that ensures that the firm retains crucial architectural knowledge, which preserves its competitive advantage. Firms therefore do not respond passively to BEE-induced changes in client preferences, but aim to meet BEE aims within their broader strategic environment.

Purpose The purpose of this study to investigate the relationships between South Africa (SA) universities and universities surrounding communities (USC) for preserving community histories and serve the universities’ mandate to support their local communities and support universities’ teaching and scholarship. Design/methodology/approach The study used a multiple case study approach through interviews. The population of the study comprised representatives from selected universities and their USC. Findings The findings revealed a lack of effective relationships between universities and USC to preserve communities’ histories. Hence, the communities’ archives are tools for teaching and scholarship. Relations between universities and USC are to be built on trust. Accountability and transparency are to be considered by both parties. Research limitations/implications The research is limited to selected SA universities, namely, University of Venda, Witwatersrand, Johannesburg, Pretoria and SA and USC. The findings are applicable to all SA universities and USC. Practical implications The relationship between universities and USC has a practical impact on the National archives of South Africa (NARSSA) to collect communities archives because it is in conflict with the mandate of NARSSA. The National Archives’ Act 43 of 1996 obliged NARSSA to collect and preserve communities’ archives on behalf of societies. Social implications Lack of universities and USC can lead to the loss of communities histories or archives. Originality/value This paper appears to be the first to research the relationship between SA universities and USC.
