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
Understanding Agency Within Context: The Case of Breeding Cooperatives Program for Transforming Small Ruminant Value Chain in Ethiopia
No full textThe role of agency in women’s empowerment, whether individual or collective, has long been at the center of feminist discourse. Although, highly context dependent, studies on agency are less contextualized. Based on mixed methods, we generated in-depth understandings of what constitutes agency in livestock-based institutions, and associated contextual factors across three regions. Agency, the ability to make effective participation, conceptualization is based on four main dimensions, in turn associated with key agency enabling resources. The agency-enabling resources such as years of schooling, land holding, sheep flock size, number of women in the leadership committee, along with location and distance to extension services variables were associated with the ability to effectively participate. Study participants are aware of the influence of normative environment but lack the power to challenge it. If supported and used as a means, the collective action, breeding cooperative, itself could potentially generate its members such power
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

The Political Economy of Rural-Urban Interfaces around Addis Ababa, Ethiopia
Full text linkThe study aims to assess the political economy of rural-urban interfaces in the pace of rapid urbanization of Addis Ababa City, the capital of Ethiopia. It seeks to understand the rural-urban interfaces employing the political economy lens of dependency theory. Primary data were collected through qualitative techniques, such as KIIs and observation methods. 20 randomly selected rural and urban dwellers were interviewed to capture their views, experiences and reflections regarding the prevailing rural-urban interfaces such as people, environment and culture. Also, quantitative data were gathered from secondary sources. The data collections and analyses were carried out between February 2013 and February, 2014. It was observed that despite there are major shifts in development policies and strategies in poverty reduction in Ethiopia, the majority of the endeavours are urban centred but rhetorically rural focused. The rural-urban interfaces in Ethiopia, as explained and underpinned by dependency view, the urban-the metropolis extracted and exploited the rural-satellite for self-development and flourishing which left the latter at the heart of underdevelopment economically, socially, politically, and contaminated the rural landscapes and environments. The find concurred with the fact that urban are dependent on rural for economic growth, environmental services and sink of waste, political instruments, and aesthetic values. As dependency perspective dictates, against the Growth Pole theory, the bias to urban metropolis is evident that caused the underdevelopment of rural satellite or periphery and flourishing urban. Thus, there is a premium need to examine the pro-rural policies of Ethiopia as it seems pseudo-concern and paternalistic promulgation but systematic, structural and technical biased towards urban in practices

Gender-based drivers of participation in sheep breeding cooperatives in Ethiopia
No full textCollective actions and formation of cooperatives are crucial for small ruminant community-based breeding programs.
Women’s participation in agricultural cooperatives is generally low in Ethiopia and the lack of participation adversely affect their ability to accrue benefits as members of cooperatives.
Although women perform most of small ruminant husbandry activities, they have less control over of the animals and associated benefits
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
