'n Vergelykende studie van twee jeugromans : Winterijs (2001) deur Peter van Gestel en Roepman (2004) deur Jan van Tonder
No full textThesis (MA (Afrikaans and Dutch))--Stellenbosch University, 2008.This thesis is a comparative literature study of a Dutch and an Afrikaans novel that can be
read by the youth and adults alike and display similarities with regard to genre, content,
structure and theme. The novels are Winterijs (2001) by Peter van Gestel and Roepman
(2004) by Jan van Tonder. Chapter 1 serves as an introduction. In chapter 2 concepts
such as “crossover literature”, “cross publication”, “dual audience authors” and “dual
audience literature” are discussed. Chapter 3 presents an overview of the theory that
provides a conceptual framework for this study. The method of investigation that is
followed by Helma Van Lierop-Debrauwer and Neel Bastiaansen-Harks (2005) in their
study of the similarities and differences between an adolescent novel for the youth and an
adolescent novel for adults is used, as well as the theory of Victor Turner (1969) on the
concept of liminality. As it provides a useful method for approaching and analyzing the
two texts, the above mentioned theories are applied to Winterijs and Roepman in
Chapters 4 and 5, with specific reference to the representation of a male child narrator
with liminal characteristics. In chapter 6 the similarities and differences between the two
novels are pointed out and summarized. Conclusions are drawn and possibilities for
further research are presented in chapter 7.Master

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
