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
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
Potential socio-economic challenges facing small-scale sugarcane production in Bungoma County, Kenya
No full textThe sugar industry is an important agricultural sector in Kenya. In 1995, the industry had employed over 35,000 workers and supported over 2 million people in the region. The sector contributes about 16% to the nation’s Gross Domestic Product. Despite of its immense contribution, its output is on decline, standing at 65 tonnes from 100 tonnes per hectare. This paper investigated socio-economic factors affecting sugarcane production in Bungoma County. The study is based on the Production Theory and Correlation Design. The targeted population was 5,838 small scale sugarcane farmers in Bumula Sub-County. The coefficient of determination indicated 67.5% variance in sugarcane output relating to the socio-economic factors of the study variables. The F value was 161.406 indicating that the regression model was fitting well. The mean variance of inflation factor (VIF) was 2.349. The study revealed that education level, farm size, land ownership, farming experience, incentives, record keeping systems, extension education, cane by-products and non-contracted cane farming had significant positive effect on cane output. Input cost was found to be a major contributor of declining cane output. The study recommends that poor cane pricing, lack of extension education and inadequate financing in the sugar sector be addressed
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
An Investigation of Coping Strategies Adopted by Small-Scale Sugarcane Growers in Bungoma County, Kenya
Get PDFThis paper reports on one of the findings of a study undertaken to investigate the coping strategies used by small-scale sugarcane growers in Bungoma County, Kenya. A descriptive survey design was used. A multi-stage sampling procedure was employed in the selection of the divisions, villages, key respondents, and sugarcane farmers to be interviewed. Primary data were collected using questionnaires from 100 small-scale sugarcane growers’ household heads from Bumula Sub-County. Data were collected during the month of December 2016. Qualitative data collected were analysed thematically. Quantitative data was analysed using regression in SPSS version 23 and Microsoft Excel. Results from small-scale sugarcane farmers in Bumula Sub-County revealed a declining farmers’ participation in sugarcane farming activities in the area. Coping strategies identified included off-farm income-generating activities, sale of sugarcane by-products and non-contracted cane farming. Significance test qualification was based on a percentage of adjusted R2 and within 0.3 to 0.7 ranges for Beta weight value. The correlation coefficient (R-value) for the model was 0.362, indicating a moderately positive relationship between variables. The coefficient of determination (R2) was found to be 0.284 (28.4%). Adopted coping strategies accounted for 28.4% variability in the declining farmers’ participation in sugarcane farming. This result suggests the existence of other factors that explain the remaining 71.6% of the variation in the declining farmers’ participation. Farmers should enhance both on-farm and off-farm income-generating activities, sugarcane by-products value addition, and non-contracted cane farming in order to reverse the outcome and result in an enhanced farmers’ participation in sugarcane farming activities by 36.2
