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
"It still recognises race" Politics of marriage and challenge of social cohesion among South Africa undergraduates
No full textSouth Africa is a country plagued by several racial challenges in almost all spheres of its activities. While, in recent years, the South Africa government have initiated programs aimed at promoting social cohesion, not much has been done in the area of interracial marriage. Yet intermarriage has been regarded as both a final test of integration and willingness of a person to lose his/her racial identification. Although some people contended that with the end of apartheid two decades ago, South Africa youth endogamy or marriage based on should be a thing of the past, studies to either confirm or refute this contention are scanty. This study, therefore, was an attempt to assess the attitudes of South Africa undergraduate students towards inter-racial marriage. The study indicated that racial endogamy is still common in South Africa, furthermore that few students are more likely to approve of the interracial marriage and the youths exhibited a conservative attitude toward interracial marriage. The study recommended that Inter-racial marriage by students and youths should be encouraged as it would likely foster social cohesion and invigorate and promote peaceful co-existence and encourage the much needed social cohesion among the people of South Africa
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
Private Investment and Political Instability: Evidence from Nigeria
Full text linkIt is a widely held opinion that the resumption of growth in Africa will require, among other things, an increase in investment, which will have to come primarily from the private sector if growth is to be efficient and sustained. Using a simple neoclassical investment model, we examined the impact of political instability on private investment. The OLS estimates indicate that political instability does not have any significant direct impact on private investment. We recommend that a political framework that does not negatively affect aggregate spending will be favourable to private investment boom.
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
