The identification of employment centres in Canadian metropolitan areas: the example of Montreal, 1996

The intrametropolitan distribution of economic activities and, specifically, the formation of suburban employment centres has become a major research and policy issue. In spite of an increasing number of detailed analyses of the geography of employment in individual metropolitan areas, no generally accepted and systematic methodology for identifying employment centres exists. Comparisons between metropolitan areas have been highly limited due to both a lack of consistent and comparable data and a plethora of methods. We first present an overview of various methods that have been used to identify employment centres. Using Montreal as a case study, we then evaluate the suitability of various methods in the light of available data on job location in Canadian metropolitan areas. The method that yields the best results is one based upon dual criteria applied at the census tract level: a total employment threshold and the ratio of employment to the resident workers. We use this method to identify the form of the Montreal space-economy in 1996. The identification of a suitable, although imperfect, method represents a first step towards being able to more objectively and systematically examine a wide range of issues concerning metropolitan economic structure.     

Dealing with the past: Museums and heritage in northern ireland and Cape Town,South Africa

The experiences of post‐apartheid South Africa have often been used to open dialogue about Northern Ireland and the possible approaches to dealing with the legacy of the conflict. People in Northern Ireland have, for example, looked towards the South African Truth and Reconciliation Commission and policing in South Africa for further insights. This comparison of South Africa and Northern Ireland has now moved beyond being concerned predominantly with conflict resolution and has come to bear in the consideration of how we should present the history of the Troubles in Northern Ireland’s museums and the value of preserving the built heritage of the Troubles. This paper uses the example of the ‘transformation’ in the South African heritage sector that came with the end of apartheid as a means to raise areas of concern that have resonance for Northern Ireland. It shows that for both Northern Ireland and South Africa it is important to think further about the impact of display, the power dynamics embedded in the construction of heritage, and the complexity of building a shared narrative from a contested past.     

Coloniality as a Barrier to Climate Action: Hierarchies of Power in a Coal-Based Economy

South Africa has a coal-based energy system and extractive economy, largely responsible for its high emission levels relative to countries with similar GDP. This extractive, coal-based economy began during British colonisation and today shows few signs of transitioning rapidly to limit climate change. This paper interrogates the role of coloniality in climate delay, given that colonisation is responsible for establishing fossil fuel dependence in South Africa. Combining theory on decolonisation, specifically colonial hierarchies of power, with a critical discourse analysis, this research uses interview and policy data to show how colonial power hierarchies can lead to climate delay in South Africa, through normalising emissions intensive development and silencing alternatives. In doing so, it highlights the need to recognise the colonial foundations of climate change and the potential for a coalition between decolonisation and climate action to motivate for radical change both in South Africa and at a global level.     

Bedding, hearths, and site maintenance in the Middle Stone Age of Sibudu Cave, KwaZulu-Natal, South Africa

Micromorphological analysis of sediments from the Middle Stone Age site of Sibudu Cave, KwaZulu-Natal, South Africa, provides a high-resolution sequence and evidence of site formation processes of predominantly anthropogenic deposits. This methodology allows for a detailed interpretation of individual anthropogenic activities, including the construction of hearths and bedding and the maintenance of occupational surfaces through the sweep out of hearths and the repeated burning of bedding. This analysis also provides a context for evaluating other studies at the site relating to magnetic susceptibility, paleobotany, paleozoology, anthracology, and studies of ochre.     

What is Geography? Perceptions of first year undergraduates in South Africa

Disciplines such as Geography are well placed to respond to the changing needs of society and the effective application of geographical knowledge to real-world problems. This project surveyed first year Geography undergraduates’ understanding of “What is Geography?”, both before and after an exercise in which geographic topics were identified within recent newspapers. The survey instrument employed was an anonymous, self-administered questionnaire, and was undertaken with first-year undergraduate Geography students at a university in South Africa. Results show that the exercise enabled students (n = 158) to more readily see the application of geographical knowledge to both environmental and social problems that they identified in the newspaper stories. Students also identified that studying Geography may be able to help them increase their skills, employment prospects and earning potential. These findings can help locate the disciplinary concerns and applicability of Geography in post-apartheid South Africa within the wider context of the twenty-first Century world.     

A critical assessment of the Hawke government's 1985 code of conduct for Australian companies with interests in the republic of South Africa

Like other Australian governments in the contemporary period the Hawke government sought to enhance its international standing by condemning apartheid. Failing to implement effective policy to match the strong criticism exposed the rhetorical character of the government's South Africa policy. Repeatedly the Hawke government found itself defending a policy framework, which in opposition it had denounced. In essence Australia's South Africa policy had displayed little principle. Refusing to play sport while maintaining bilateral trade and investment with South Africa, underscored the contradictory basis of Australia's South Africa policy. In an effort to redress this policy imbalance the Hawke government chose to enact an employment code for Australian employers of black South African labour. The government promoted this element of policy as a substantial advance in reformulating its overall policy approach. Archival documents and material released under the Freedom of Information Act reveal a very different image.     

Contextualising the AIDS epidemic in the South Pacific: orthodoxies,estimates and evidence

There is a growing consensus that HIV/AIDS is a ‘time bomb’ ticking in the South Pacific. This may, in fact, be the case. However, there are at least two major problems with this approach. First, analysis of the implications of the epidemic is based on supposedly concrete links between the epidemic and social, economic and political outcomes. Many of these apparent links have not been established (because the data is not available for the South Pacific). As such, much of the method for analysing the ramifications of the epidemic is borrowed from elsewhere, notably Africa, and the strength of these links is beginning to unravel. Second, research on the vectors of the epidemic that informs this consensus is only as good as the data that it relies on. There are major testing and surveillance gaps in the South Pacific that mean projections are often based on patchy and incomplete data. This can dramatically skew priorities. Reflecting on these problems is important because of the clear ramifications they pose for the development of good public policy in, and toward, the South Pacific.     

A late Middle Stone Age artifact assemblage from Sibudu (KwaZulu-Natal): comparisons with the European Middle Paleolithic

It has been suggested that many behavioral innovations, said to appear during the late Middle Stone Age in sub-Saharan Africa, facilitated the expansion of anatomically modern humans from Africa and the Near East into Europe at about 50 kyr; the process eventually led to the replacement of Neanderthals by modern humans and the emergence of the Upper Paleolithic. However, assemblages in this time range are little known in South Africa. In fact, the transition from Middle to the Later Stone Age in Southern Africa is controversial. The early appearance in South Africa of many innovations, such as sophisticated knapping techniques (e.g. the use of soft hammer or indirect percussion in blade production, of composite tools, of microlithic and bladelet technologies) remains to be established through technological analysis.We present here the first results of a project designed to carry out detailed technological studies of several lithic assemblages in South Africa and France dated to the transition period. At this time we have completed the study of a post-Howiesons Poort assemblage from the rock shelter site of Sibudu.The >2 m deep stratigraphic sequence of Sibudu extends from Howiesons Poort at its base to final Middle Stone Age, directly under Iron Age layers. We have analyzed in detail layer RSP (ca. 53 kyr, 1 m above the Howiesons Poort levels) which has provided a large assemblage of several thousand stone artifacts. Compared to published MSA assemblages this industry is unusual for the very high proportions of retouched pieces (15%). The technology is not very elaborate and there is no strong standardization of the end-products. There are no flakes of predetermined shapes; retouch is used to modify irregular flakes to obtain desired edges. Knapping of flakes and blades is done by hard hammer; soft hammer is used only for retouching tools. Interestingly the older Howiesons Poort blades were produced on the same raw materials by soft hammer. Raw material (hornfels and dolerite) was procured from distances of less than 20 km. Unifacial points are the dominant type and there is strong evidence of hafting and use as spear armatures. Detailed comparisons with Middle Paleolithic assemblages of Western Europe show that the late Middle Stone Age technology in South Africa is very similar to that of the Middle Paleolithic; in fact we see no fundamental differences between the two entities, as far as lithic technology is concerned. Implications for the Out of Africa hypothesis are discussed.

Historical Perspectives on Pre-Colonial Irrigation in Southern Africa

Abstract

One of the basic areas of interaction between water as natural resource and human societies as agents of cultural transformation is the technology of irrigation. In Africa at least 66 per cent of the available water is used for purposes of irrigation. For more than 4 000 years irrigation has secured food supplies for humans on a continent that is noted for its relative shortage of sufficient natural water supplies.

There is a remarkable hidden power of water in the history of southern Africa. This is particularly the case when we consider the development of early irrigation technologies of Iron Age farmers. The small irrigation furrow of the subsistence farmer was just as important to an insular community of Bantu-speaking people in pre-colonial times, as is the sophisticated irrigation technology in present-day South Africa. Currently there is a paucity of information about pre-colonial indigenous irrigation technology. This can be ascribed to a number of factors of which the invasion of modern Western traditions in the nineteenth century is perhaps the most important. A number of other factors for the apparent blind-spot is also presented in this study.

In southern Africa there are traces of indigenous pre-colonial irrigation works at sites such as Nyanga in Zimbabwe; the Limpopo River Valley; Mpumalanga; and South Africa's eastern Highveld. Reference is also made in this article to specific strategies of irrigation used by Iron Age communities, prior to the advent of a colonial presence. Finally, attention is also drawn to pre-colonial land tenure and state formation against the backdrop of Wittfogel's theories on hydraulic society.     

An investigation of climatic change in the holocene epoch using archaeological charcoal from Swaziland, Southern Africa

A methodology is described for the analysis of Holocene charcoals excavated from a rock shelter in the Lubombo Mountains of northeast Swaziland. Scanning electron microscopy was used to compare these with modern reference woods. Of the ancient material 96·6% could be identified, in some cases at specific level. It is in such a subtropical area, where the woody flora is so rich, that assemblages of local taxa can be used in palaeoclimatic reconstructions. The changing taxa indicated by the charcoal fragments from the rock shelter clearly reflect minor shifts in Holocene climate, from moist to dry and back to moist in recent times. This is of relevance to the fluctuations in Stone Age populations in southern Africa. The wider use of such evidence to complement other palaeoenvironmental and archaeological data is advocated.     

The Poliomyelitis Epidemic in Johannesburg in 1918: Medical and Public Responses

ABSTRACT

This article traces the appearance of poliomyelitis in Johannesburg during the first recognised epidemic in South Africa in the early months of 1918. The course of the epidemic is examined by reviewing available statistics and investigating the problems that the epidemic imposed on medical and health authorities, both locally and within higher echelons of power. The response of the Johannesburg community to the disease is explored, as are the treatments available to polio patients at a time when the disease was regarded as ‘a mystery’. The place of the 1918 epidemic in the wider history of polio in South Africa is also explored.     

Using an Evolutionary Algorithm in Multiobjective Geographic Analysis for Land Use Allocation and Decision Supporting

Usually, allocation of resources is an optimization problem which involves a variety of conflicting economic, social, and ecological objectives. In such a process, advanced geographic analyst tool for manipulation of spatial data and satisfaction of multiple objectives is essential to the success of decision‐making. The present research intends to demonstrate the application of a multiobjective optimization method based on NSGA‐II 1 (we call it HNSGA‐II), along with Geographical Information System (GIS) 2 to select suitable sites for the establishment of large industrial units. Having defined the elements of HNSGA‐II for the site selection of industrial units, the method is tested on the data of Zanjan province, Iran, as the case study. The results showed that the proposed approach can easily find a variety of optimized solutions, giving the decision‐makers the possibility to opt for the most propitious solution. Using this method, the achievement level regarding each objective function can be studied for any of the nondominated solutions.     

Maximum Possible Ground Motion for Linear Structures

This article develops a method to generate ground motion time histories that maximize the response of a given linearly elastic structure. The root mean square (RMS) level of the input power spectral density (PSD) is used as a strong motion parameter. It is related to seismological data that is readily available. An empirical relation to estimate RMS value of the PSD from peak ground acceleration, magnitude, rupture distance, and shear wave velocity is derived from world-wide strong motion data. The ground motion is obtained by solving the inverse problem such that the structural response is maximized under the constraint of fixed value of RMS level of the input PSD enforced using a Lagrange multiplier. The proposed methodology is illustrated for a single-degree of freedom system, a six storey building and an earthen dam. It is shown that the critical PSD obtained in all the cases is a narrow band process resulting in stochastic resonance and not a Dirac-delta function with the entire energy of the system concentrated at its natural frequency. Moreover, the critical excitation samples generated using this critical PSD resembles actual earthquake acceleration time histories.     

Hegel and Historicism

Abstract

This article summarises the story of the production of the historical volumes by the South African Democracy Education Trust (SADET). SADET was established after former president Thabo Mbeki expressed concern that there was very limited research done on the achievement of a peaceful political settlement in South Africa after decades of violent conflict. SADET's mission is, and has been to conduct a major study of South Africa's political history between 1960 and 1994. The focus of the article is on the project's editorial structure and on its research methodology, particularly the benefits and limitations of the use of oral interviews as the main research tool.     

Small Area Population Estimation: Estimating Population Size at Ward Level 2014 in South Africa

The census is the traditional source of population figures at various levels. Census figures however are technically outdated immediately they are released because planners require figures for the present and possibly for future dates. In an attempt to meet this demand different organisations and researchers produce population estimates and projections. These estimates however are usually at higher geographical levels and often do not meet the planning needs of administrators at lower geographical levels. This study extends a top‐down estimation method to an African country by estimating the mid‐2014 population at ward level in South Africa. The study used the 2011 South Africa Census to estimate current levels of fertility, mortality as well as current trends in net migration at a higher geographical level. Historical trends in fertility and mortality were based on the 1996 Census, 1997 and 1998 October Household Surveys as well as the 2007 Community Survey data. The results indicate that that 20 of the largest wards as at mid‐2014 were located in South Africa's metropolitan areas. Nineteen of the 20 largest wards are currently growing at a rate of over 4% per annum and if this trend continues, eighteen of these wards will double their current population size in less than 15 years.     

Principal Component Regression in Spatial Lag Model: Teen Employment in the City of Rosario,Argentina

Teen employment is a very important socioeconomic phenomenon because of its consequences on human capital formation. We assess the relation between teen employment and poverty, education, and unemployment in the city of Rosario, using information from the 2010 Argentina Census disaggregated at census block level. We use two different spatial models: The spatial lag model (SLM) and a linear regression model with the spatial component filtered (filtering model, FM). Given the nature of the variables employed, multicollinearity is an issue. One of the techniques proposed in the literature to deal with multicollinearity problems is principal component regression (PCR). We develop an adaptation of such methodology to be used in the SLM. Both models are estimated using their traditional methodologies (instrumental variables for the SLM and OLS for the FM) and using PCR. Although results are similar between the two models, depending on the methodology used in the estimations they differ greatly. Under traditional methodologies estimations show high variability, instability, and contradictory outcomes, but under PCR, results behave according to the literature.     

Campaigning Against Apartheid: The Rise,Fall and Legacies of the South Africa United Front 1960–1962

ABSTRACT

The international struggle against apartheid that emerged during the second half of the twentieth century made the system of legalised racial oppression in South Africa one of the world’s great moral causes. Looking back at the anti-apartheid struggle, a defining characteristic was the scope of the worldwide efforts to condemn, co-ordinate, and isolate the country. In March 1961, the international campaign against apartheid achieved its first major success when Prime Minister Hendrik Verwoerd chose to withdraw South Africa from the Commonwealth following vocal protests at the Heads of State Summit held in London. As a consequence, it appeared albeit briefly, that external pressure would effectively serve as a catalyst for achieving far-reaching and immediate political change in South Africa. The global campaign, centred on South Africa remaining in the Commonwealth, was the first of its kind launched by South Africa’s national liberation movements, and signalled the beginning of thirty years of continued protest and lobbying. The contributions from one organisation that had a role in launching and co-ordinating this particular transnational campaign, the South Africa United Front (SAUF), an alliance of liberation groups, have been largely forgotten. Leading members of the SAUF claimed the organisation had a key part in South Africa’s subsequent exit from the Commonwealth, and the purpose of this article is to explore the validity of such assertions, as well as the role and impact it had in generating a groundswell of opposition to apartheid in the early 1960s. Although the SAUF’s demands for South Africa to leave the Commonwealth were ultimately fulfilled, the documentary evidence suggests that its campaigning activities and impact were not a decisive factor; however the long-term significance of the SAUF, and the position it had in the rise of the British Anti-Apartheid Movement (AAM) has not been fully recognised. As such, the events around the campaign for South Africa’s withdrawal from the Commonwealth act as a microcosm of developments that would define the international struggle against apartheid.     

Social divisions carved in stone or cenotaphs to a new identity? Policy for memorials,monuments and statues in a democratic South Africa

Popular protests in 2015 in South Africa around statues and memorials, sparked off by the #RhodesMustFall campaign, drew attention to heritage policy and practice in the country since the advent of democracy in 1994. The protests and commentary in social and other media revealed the extent of polarisation along racial fault lines in South African society. They also exposed the apparent failure of official policy implemented for more than 20 years of promoting heritage for the purposes of nation building and social cohesion. Numerous writers have analysed heritage in South Africa since the transition to democracy, but none has traced the details of the evolution of heritage policy within the ruling party and government. This study seeks to shed light on the current debates on the politics of heritage in South Africa by examining the various policy processes and practices within the ruling African National Congress and the government. It argues that many of the heritage practices and policies in South Africa are rooted in the apartheid past and that failure, especially by decision-makers, to critically interrogate these has led to the stunted transformation of society and the current ferment.     

Apartheid,Religious Pluralism,and the Evolution of the Right to Religious Freedom in South Africa

The apartheid history of South Africa contains racial and religious discrimination, both running parallel to and supporting each other. South Africa's exodus from a society of forced religious homogeneity to one of celebrating religious pluralism adds valuable and unique patterns of thought to the promotion of religious pluralism and religious freedom. A brief history is presented of religion within the context of racial discrimination and eventual democracy in South Africa. The current plural religious demography of South Africa is presented to create a sense of the extent of diversity in the country and the extent of religious pluralism that should be considered for today. This demographical position necessitates an investigation into the current legal position on dealing with such a religiously plural state as well as the challenges it presents. This is also necessary in order to present the evolution of religious pluralism in an oppressive state to the right to religious freedom in democratic South Africa. This evolution can also serve as an example internationally to countries struggling with the issue of religious pluralism. The article is also of importance to sensitise South Africa to existing and escalating challenges against religious pluralism within the country.
