    Die Suid-Afrikaanse funksionele metropool: ‘n sintese

    Get PDF
    Confusing usage of terms such as metropolis and metropolitan region in planning policy in South Africa has led to the need for a fundamental investigation into the morphological and functional properties of the country’s three largest cities. Using Gauteng, Cape Town and Durban as examples, the article distinguishes between different elements of functionality of metropolitan areas linking urban function to urban form. Starting at the global level and zooming in, the article examines metropolitan functional space at the national through the regional to the local level. Semantically, it distinguishes between the terms metropolis and megalopolis; daily and weekly urban systems; and between urban monocentricism, multinodality and polycentricism. Based on morphological differences, it classifies Cape Town, Durban, Pretoria and the Witwatersrand as metropolitan areas, but regards the sprawled urban agglomeration in Gauteng as a megalopolis. A case is also made for greater recognition of the daily urban regions of the three primary cities of South Africa as part of the larger urban system of each. Planning has focused for too long on metropolitan space inside the urban edge and too little on those parts of the cities that lie outside the edgeDie verwarrende gebruik van terme soos metropool en die metropolitaanse streek in beplanningsbeleid in Suid-Afrika lei tot ‘n behoefte aan ‘n fundamentele ondersoek na die morfologiese en funksionele eienskappe van die land se drie grootste stede. Deur gebruik te maak van Gauteng, Kaapstad en Durban as voorbeelde tref die artikel ‘n onderskeid tussen verskillende funksionele elemente van metropolitaanse gebiede waarin stedelike funksie en stedelike vorm verbind word. Beginende by die globale vlak en deur in te fokus op die nasionale, streek- en plaaslike vlak word daar in die artikel gekyk na metropolitaanse funksionele ruimte. ‘n Semantiese onderskeid word getref tussen die terme metropool en megalopool; daaglikse en weeklikse stedelike sisteme, en tussen monosentrisme, multinodaliteit en polisentrisme. Gebaseer op morfologiese verskille word Kaapstad, Durban, Pretoria en die Witwatersrand as metropolitaanse gebiede geklassifiseer, maar word die verspreide stedelike kompleks van Gauteng as ‘n megalopolis beskou. ‘n Saak word ook uitgemaak vir groter erkenning vir die daaglikse stedelike streke van die drie primêre stede van Suid-Afrika as deel van die groter stedelike sisteem van elk. Vir te lank het die klem in beplanning op metropolitaanse ruimte binne die stedelike grens geval en te min op die deel van die stede wat daarbuite va

    An edited group of 21 papers on urban change; in addition, the author contributed the four initial chapters on theoretical methods. The remaining papers consider factors of urban change, mostly for the latter part of the 20th century, for countries in Europe, the Americas, South Africa, and Asia. Themes include migration, population change, and the impact of political change. The international group of contributors is made up of academics in geography, urban and regional planning, and demography

    Faculty of Arts and Social Sciences. Dept. of Geography and Environmental Studies.Thesis (MA)--Stellenbosch University, 2019.ENGLISH ABSTRACT: In different parts of cities and in different income areas, transit-oriented development (TOD)precincts take a different shape and form,making the spatial distribution of property ownership within precincts an integral determining factor inshaping precinct development. This study looked at differentprecincts in the different parts of the Cityof Tshwanewith different average household income, using population characteristics and transport relationships to highlight what the precincts representin the peripheral and inner-city parts of the Cityof Tshwane. Using geographic information systems (GIS)products and techniques to display and analyse the relationship between the different population variables,inferences were made about the functioning of precincts, challenges and prospects for future growth for the precincts.This study found that administrative regions 1, 3 and 6 of Tshwane peripheral precincts have a clustering of business and commercial land uses in the middle of the precincts that act as central business districts (CBD). The government owns most non-residential properties in the precincts,and the precincts themselves represent important commercial nodes for their catchment low-income subplaces. Transport relationships in these regions arecompetitive and the feeder options are minimal. In the inner city administrative region 3, precincts in middle-income areasrepresent classification categories of precincts with an abundance of transit options called city centre, while trunk and feeder options exhibit a complementary relationship between the transport options. Administrative regions 1, 4 and 6, which are high-income inner-city precincts, representthe urban class and are only valuable to their surroundingMaster

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
