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
Adaptability Study of Yield and Yield Related Trait Performance of Improved Food Barley (Hordeum Vulgare L.) Varieties in North Shewa Zone Oromia, Ethiopia
Get PDFBarley is one of the founders, old world agriculture and the first domesticated cereal crop. It is a staple food, adapted to and produced over a wider range of environment . This trial was conducted on sixteen improved food barley varieties with one local check at Fitche Agricultural Research Center for two consecutive years. The objective was to identify adaptable, stable and high yielding varieties. The seed was sown in Randomized Complete Block Design with three replications. Nine agronomic traits data were evaluated. Analysis of variance detected significant difference among varieties for most observed traits both separated and combined analysis. Observation attained significant differences over years and locations for almost all traits. The combine ANOVA and the AMMI analysis for grain yield across environments revealed significantly affected by environments, hold 68.4% of the total variation. Genotype and genotype by environmental interaction were significant and accounted 12.1 % and 17.8 % respectively. Principal component 1 and 2 accounted 9.6% and 4.3 % of the GEI respectively with a total of 13.9 % variation. The interaction effect of variety by year and variety by location imposed significant effect on most traits. Among evaluated varieties; HB1307 and HB1966 had significantly higher mean value of grain yield. Moreover, the yield advantage of 32.9% and 38.8% were estimated for HB1307 and HB1966 respectively over the local check. Therefore, these varieties were suggested for further demonstration and popularization in the areas with similar agro-ecology

Evaluation of Improved Durum Wheat (Triticum turgidum var. durum) Varieties in North Shewa Oromia
Get PDFEvaluating durum wheat varieties in various conditions is crucial in determining their stability performance and adaptability. In this study, 10 durum wheat varieties were evaluated in four sites to examine genotype-environment (G E) interactions and their effect on yield stability across varied environments. A field experiment was conducted at the four stations of Fitche Agricultural research center for two consecutive years. The experiment was layout in Randomized Completed Block Design (RCBD) with three replications. Nine agronomic and yield-related trait data were evaluated and analyzed. The pooled over- locations analysis result indicated that significant differences among tested varieties for most traits including grain yield were observed. The maximum grain yield was recorded from Gerardo variety with mean of 2156.2kgha-1 where as the minimum was recorded from Tesfaye variety. The results of the GGE biplot revealed that the variety "Gerardo" is stable across the testing locations since it is situated inside the concentric circle. In order to enhance the production of durum wheat in Northern Oromia other similar ecologies, the Gerardo variety was found to be the most stable and productive variety
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
