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

Characterization of Sheep Fattening Cooperatives in Ethiopia: Member Satisfaction and Female Participation
No full textCooperatives play crucial roles in economic and social development of both men and women. The study was conducted to determine the participation of sheep farmers in sheep fattening cooperatives (SFC) in four regional states of Ethiopia with a special focus on women. Variables studied included characteristics of members, length of membership (LM), extent of participation in decision making (EPDM), satisfaction of the level of management (SLM), interaction with cooperative officials (ICO), interaction with members (ICM), satisfaction level on interaction (SLI), members taken into consideration (MTC), annual revenue of the cooperative (ARC), share of meetings attended (SMA), Fifty four legally registered SFC were selected purposively based on their current status and their accessibility. Probability proportionate to size (PPS) technique was used to determine the number of producer members to be studied. A total of 314 members and 54 chairpersons of the cooperatives were interviewed using structured questionnaires. Descriptive statistics (mean, percentage and frequency) and econometric model (tobit and logit) were employed for data analysis using Statistical Analytic Software (SAS) ver. 9.2. Results showed that the majority (69.7%) of members in SFC were men. The SFC in this study showed no trend of increasing membership. Members (53.8) participated moderately in decision making, while 38% had a moderate level of satisfaction in the management. There were high levels of interaction as shown by proportions of producer members who interacted with officials (58.8%) and among themselves (60.4). The proportion of members who attended all cooperative meetings was 30.6%. There were no correlations between age of members and length of membership with other variables. EPDM was strongly correlated (P0.05) with ICO. From the result of this study, majority (68.9%) of respondent members have no intention of increasing the number of sheep per fattening cycle. Poor market linkage and information, feed, cash and space ranked 1st, 2nd, 3rd and 4th as factor that limit the number of fattening sheep per cycle. Internal factors were mentioned to have a strong influence on the future existence of SFC as compared to external factors. There was a significantly higher (P< 0.05) proportion of women membership in SFC initiated by NGOs and cooperatives that have women in the leadership positions. There was significantly lower (P<0.001) proportions of women in SFC whereby members buy shares at the start-up. The level of literacy had an effect on women's participation in leadership. Women had a higher chance of being leaders in SFC that were women-based, those with higher proportions of female membership, and those with leaders who have undertaken gender-related training courses. Membership in SFC resulted in improved women's access and control over inputs and resources, training and credit, and participation in decision making and management activities. However, their proportion and participation in leadership of SFC is still limited. Therefore, awareness creation and gender inclusive trainings, access to resources and education should be done and improved in order to involve women effectively in cooperative development
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
Characterization of Sheep Fattening at Small Holder Level in Different Agro-Ecological Zones of Ethiopia – Amhara Region
No full textThe purpose of the study was to characterize sheep fattening production system at small holder level in rural areas of Ethiopia, based on different agro-ecological zones (AEZs). 108 small holder sheep fatteners were selected by random sampling out of Amhara region. Therefore, three AEZs within Amhara region made a total of 12 study areas, each with about 36 respondents who were selected purposively, based on the relevant activity and accessibility to transportation. The collected data from the questionnaire was analyzed based on software, SPSS. The result of the region showed that the sheep fattening practice in general, in different AEZs, was found relatively more defined in the highlands, than in the mid lands and the low lands, respectively. Better market demand, shorter distance to health center, qualitatively and quantitatively feed resources availability, higher net profit gain, relatively better market value chain were scored in the highlands than the rest, followed by mid land and the least score in low lands. The high temperatures in the lowlands influenced health problem which ultimately resulted in low production. Even so, the fattening production system is semi- intensive even in better scoring areas and declines to extensive in most cases. But in fulfilling the constraints of each AEZ would enable them to have optimum and relatively, similar production potential. Besides, using appropriate breeds, market chains, distribution of industrial by-products and promotion of loans supported with agricultural inputs would encourage the small holder farmers to engage in sheep fattening, consistentl
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
