Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Investing in Agricultural Mechanization: A Means to Realize Crop Production Targets for the Growth and Transformation Plan (GTP) of Ethiopia
Ethiopian economy is dominated by the agriculture sector and its contribution is vital to the national growth domestic product (GDP). Accordingly, cropproduction, will remain the major source of growth in the growth and transformation plan (GTP) of Ethiopia. Increasing the productivity of the smallholder farmers through scaling up of best practices, expansion of irrigation, natural resource conservation, production of high value crops and encouraging the private sector are among the strategic approaches in the GTP of the country. In realizing this, improved agricultural mechanization technologies must be taken as one of the critical factors as they enhance production and productivity through timeliness, better quality of operations and precision in application of biological and chemical inputs. Furthermore, they can contribute to adaptation to climate variability and change and addressing social issues of gender and youth. Therefore, this paper discuses the need for investing in agricultural mechanization sector through formulating clear strategies that encourage the whole value chain and developing the capacity of stakeholders that guarantee the availability and sustained use of the technologies to meet the envisaged targets. 
School management and decision-making in Ethiopian government schools: Evidence from the Young Lives qualitative school survey
Both academic and policy documents indicate that poor school management and decision-making at local level are major challenges in creating equitable access to good-quality education in Ethiopia. In principle, educational provision can be improved through better management practices, transparency in the use of resources and accountability to all stakeholders (community, parents, students, teachers, etc.). This study focuses on school management and decision-making in government schools and is based on the qualitative data collected in 2010 as part of the Young Lives school survey. The paper examines the extent to which the involvement of different stakeholders in schools (teachers, headteachers, parents, students, local government administration, etc.) impacts upon critical decision-making at school level. The paper uses qualitative data collected as part of the recent Young Lives school-based research from five of the 20 sentinel sites. Specifically it uses data collected through in-depth interviews with teachers and headteachers. It is only in recent years that the Ethiopian Government has paid attention to the importance of school management and school-level decision-making. Research in the area of school management is almost nonexistent in Ethiopia. However, various reports and policy documents prepared by the Federal Ministry of Education clearly indicate the extent to which the Government has been focusing on improving school management in recent years (MOE 2005; MOE 2010a). The paper examines how headteachers and teachers contribute to the strengthening of the day-to-day management and supervision of schools attended by Young Lives case study children
Indicators for Gauging the Effectiveness of Dairy Extension in Ethiopia
Modern extension system is being undertaken since 1950s in Ethiopia. However, majority of the farmers still use traditional dairy practices. This study was carried out to assess the effectiveness of dairy extension in disseminating dairy technologies/practices. A cross sectional survey was employed using 50 extension workers in the area of livestock sector. Almost all the selected study variables were significantly influencing the effectiveness of dairy extension. The value of dairy extension effectiveness index was also low. It necessitates integrated strategy; capacitating extension workers; and selection of model farmers those represent the majority of the farmers in the jurisdiction area. Keywords: Dairy extension, dissemination, extension effectiveness index, extension worke
Variations on the Author
“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
We 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
We 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
We 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
