No full textThis paper evaluates the impact of globalisation on the domestic South African economy (1993 – 2001). With a Gini coefficient of 0.593 (World Bank 2000a) South Africa has one of the most unequal income distributions in the world. South Africa has experienced increased capital flows during this time. Unfortunately, these were in the form of portfolio investment rather than much-needed direct investment. There is no indication that increased capital flows have contributed to economic growth or improved the living conditions of average South Africans. Globalisation did not succeed in creating jobs

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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 PDFWe 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
Getting to know the Amakwerre-kwerre: the socioeconomic circumstances of Zimbabwean day labourers in South Africa
No full textOver the past decade, in the face of volatile economic conditions at home, there has been
an influx of Zimbabweans into South Africa looking for work and a better life. Many of
these jobseekers have moved into the day labourer market, offering their services on street
corners and other pickup points in the main metropolitan areas. While their working and
living conditions leave much to be desired and their pay is very uncertain, Zimbabwean
day labourers – with better education – often are the preferred candidates for the limited
jobs on offer and earn more than their counterparts in South Africa. Not surprisingly,
South African day labourers often resent Zimbabwean workers in the country. This study
is the first of its kind in that it delves into the hopes, fears and daily routines of
Zimbabwean day labourers, and offers new perspectives on this important economic
segment
Globalisation and its effect on the South African labour market: evidence from the manufacturing sector
No full textEnglish: This article investigates the impact of globalisation on employment and wages in the South African manufacturing sector for the period 1993 to 2001. Globalisation has led to a more open economy. Export volumes have increased and manufactured goods have gained ground in relation to mining products. Within the manufacturing basket, labour-intensive goods have become more important. Productivity has increased, but there has been no nett job creation or incrrease in unskilled wages. Regression results indicate that exports have a positive effect on employment, but only for highly skilled workers, not for semi-skilled or unskilled employees.Afrikaans: Hierdie artikel ondersoek die impak van globalisering op indiensname en lone in die Suid-Afrikaanse vervaardigingsektor vir die periode 1993 tot 2001. Globalisering het tot ’n oper ekonomie gelei. Uitvoervolumes het gestyg en vervaardigde goedere het relatief tot mynbouprodukte in belangrikheid toegeneem. Binne die vervaardigingsmandjie het arbeidsintensiewe goedere ook belangriker geword. Produktiwiteit het toegeneem, maar daar was geen netto toename in werkskepping nie en ongeskoolde lone het nie gestyg nie. Regressie-analise toon dat uitvoere ’n positiewe uitwerking op indiensname het, maar slegs vir hoogs geskoolde werkers en nie vir semi- en ongeskoolde werkers nie.Publisher's versio
