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
Internationalization and competition in small manufacturing firms
Full text linkThis study focuses on three topics in the behaviour of small manufacturing firms using theories from industrial economics as theoretical benchmarks. The study takes as its starting point the perspective of the individual enterprise rather than that of an industry or a market. For the study a considerable amount of new data was collected by interviewing about 80 small business managers in Finland up to three times by the end of 1997. The first of the three parts of the study considers the adoption of an export strategy. The non-linear econometric model adopted suggests that the adoption of an export strategy in small firms is in particularly influenced by the language skills of entrepreneurs, and has become faster over time. The second chapter provides insights into the differentiation behaviour of industrial small firms. At the individual firm's level, vertical differentiation seems to have a special weight since horizontal differentiation is often limited by the requirement of technical compatibility, and because improving quality is perceived to incorporate lower risk than differentiation based on taste differences between customers.
The third chapter studies exiting from export markets using the case-study method of research. There is no strong case for, or against, the export hysteresis in the data, and thus one can argue that the behaviour of the firms has been largely in accordance with the standard theory of a competitive industry. The lack of an explicitly export strategy and concentration on exports to one country seem to contribute to exit where the nature of exporting can be described as opportunistic. Overall, the firm-level study presented here suggests the relevance of further studies using models of diffusion of innovations to theorize small business exporting and to taking better into consideration of an individual firm's perspective in studies on product differentiation. Moreover, demand side influences on export hysteresis should be studied further
