Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
A social and economic impact assessment of the South African mineral and petroleum resources development act on the small-scale diamond mining sector
No full textIncludes bibliographical references.The small-scale mining (SSM) sector in South Africa has been overshadowed by the wealth generating capacity of the formal mining industry. To address the disparity between the SSM sector and the large formal mining industry, a number of government initiatives have been introduced, the latest being the preparation of the Minerals and Petroleum Resources Development Act 28, which was finalized in October 2002. The Act, which has not yet been implemented, is expected to redress some of the sector's current obstacles. Two case studies conducted in the Northern Cape and North West Provinces, provided the basis for this social impact assessment (SIA). The aim of these studies was to identfy the most serious issues faced by the SSM sector and to assess the likely socio-econiomic impacts of the Act
Confronting black low cost housing delivery in the Western Cape Metropolitan Area : a critical appraisal
No full textBibliography: pages 333-338.This thesis presents a critical evaluation of the current responses being made by the new Government of National Unity towards solving the low cost housing and community development crisis. This crisis is largely confined to the black low-income residential areas and is manifest in a shortage of adequate formal accommodation, municipal infrastructure and public facilities. Moreover, these areas are also characterised by poverty, poor living conditions, environmental degradation and the socio-economic deprivation of the households living within them. The Reconstruction and Development Programme and the National Housing Policy have recently been introduced by the new Government in response to this problem. The purpose of this study is to examine the degree to which these policies represent an effective long-term solution to this crisis and whether they are an appropriate means through which low-income households can obtain the type of housing-they both need and can realistically afford. Emphasis is placed upon a critical evaluation of the National Housing Policy and the Cape Metropolitan Region is used as a study area. A household survey was carried out in the black low-income residential areas of this region in an effort to determine the actual housing and development needs, perceptions, socio economic characteristics and locational preferences of these communities. The results of the survey are presented along with an analysis of the origins, nature and magnitude of the housing crisis in the Cape Metropolitan Area

An environmental impact assessment of urbanisation in the Erongo Region, Namibia
No full textBibliography: pages 97-102.The assessment conducted in this dissertation was shaped by the intended formulation of an Integrated Coastal Zone Management Plan (ICZMP), as proposed by the Danish Co-operation for Environment and Development. An ICZMP provides an integrated and holistic approach to planning, in which the various activities and resource demands that occur within the coastal belt and neighbouring regions are appropriately coordinated. The first phase of the formulation of this management plan entailed the compilation of a baseline report summarising the present state of the environment in the study area, with particular emphasis on the major issues which will require attention in an ICZMP. This study was undertaken by Masters students from the Department of Environmental and Geographical Science at the University of Cape Town. The study area is located within the coastal belt of Namibia's Erongo Region, and more specifically within the magisterial districts of Swakopmund and Walvis Bay (Map 3). This includes the National West Coast Tourist Recreation Area and a portion of the Namib Naukluft Park. The southern boundary extends to the Sandwich Harbour, while the northern boundary extends to the southern bank of the Ugab River. The eastern perimeter is that of the Swakopmund magisterial district, and includes the municipal areas of Walvis Bay, Henties Bay and Arandis, together with Rossing Mine and its immediate environment. The seaward boundary is defined by the three nautical mile limit from shore. The Baseline Report: Coastal Zone Management Plan for the Erongo Region, Namibia was submitted to DANCED in March 1996. The findings of the investigation, as recorded in the report, highlight a number of issues which require urgent attention in the ICZMP. One such issue concerns the rapid influx of migrants to the urban centres in the study area. Population is a determining factor which significantly influences the functioning of other key sectors within a given location. As such, an understanding of the ramifications of increased population numbers is imperative to the formulation of an ICZMP. The objective of this dissertation was, therefore, to identify the factors generating rapid migration to the study area, and to facilitate an assessment of the impacts of this phenomenon. Once identified and assessed, these impacts can be better managed within a holistic, integrated framework
Integration in spatial planning : case study of the Cape Town Metropolitan spatial development framework
No full textBibliography: leaves 130-139.It is the underlying position of this thesis that -sustainable development embraces the concept of integrating economic, social, environmental, demographic and political issues. High levels of poverty and previous unequal access to resources and power in South Africa emphasise the need for an integrated approach, with a critical focus on democracy, participation and transformation of institutions. Sustainable development requires trade-offs, for example through regulatory frameworks. City managers use these frameworks provide a just and equitable means for informed, integrated and sustainable decision-making. The thesis, in terms of theory and precedent attempts to derive an understanding of What integration is in terms of the broader context of sustainable development and how it is perceived in both Spatial Planning and Strategic Environmental Assessment processes. although both have, at times, common objectives, they have different rationales and the assumption is made that spatial planners believe their procedures and methods pare sufficient for the integration of biophysical, social and economic issues. The question is: how is it possible to ascertain whether integrated planning is occurring? The intention of this thesis is to evaluate the extent of integration which occurred in the Cape Town Metropolitan Spatial Development Framework (MSDF). The Integration Framework is used as a tool to evaluate the MSDF - it constitutes five dimensions, substantive, methodological, procedural, institutional and policy integration. These provide the criteria for determining the extent to which integration has occurred in the MSDF. The MSDF process was initiated in 1991 and was the first planning exercise attempting to change the city structure and reverse the legacy of apartheid. It took into account the unique environment of the Cape, its people and the economy; the plan itself was prepared during a period of political, legislative, institutional and social change. The MSDF was adopted in 1996 by the Cape Metropolitan Council. An Environmental Evaluation was also done for the first time at metropolitan level, giving the spatial planning process a new dimension
An assessment of resettlement programmes in Southern Africa
Full text linkThe resettlement programmes in Zimbabwe, Namibia and South Africa aim to provide secure access to natural resources and infrastructure for landless people within rural areas, in order for them to achieve self sufficient livelihoods through the production of agriculture. Resettlement programmes are a development initiative and a component of rural development. In order for the resettlement programme to be a positive component of rural development by contributing to economic development and improving the welfare of the beneficiaries, the correct procedures need to be followed in the planning and implementation stages. The aim of the study is to establish a set of criteria for assessing resettlement programmes. Zimbabwe's resettlement programme is reviewed to assist in the establishment of the criteria. The criteria is used to evaluate the two case studies, namely, resettlement schemes at Garn, in Namibia and on Elandskloof, in South Africa. Guidelines are developed from the criteria to assist in the planning of resettlement programmes. Unless effective planning which takes the socio-economic and biophysical environments of resettlement areas into consideration, the objective of resettlement programmes practicing sustainable resource use, is reduced
