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
Evaluation of the impact of the agricultural insurance program of PCIC on rice producers in region VI
No full textRice is the most important agricultural commodity in Western Visayas, being one of the top producers of rice in the country. Rice production, however, is a highly risky venture in disaster-prone Philippines. Majority of the rice farms in the region are small farm holders who are more vulnerable to crop damages and diseases. To reduce small farmers' vulnerability, the government provides social insurance through the Philippine Crop Insurance Corporation (PCIC). Crop insurance is viewed as a risk management tool that can stabilize farmers' income and consumption after experiencing perils, hence a promising strategy to reduce poverty. With the substantial amount of public funds that goes to PCIC, it is important to know whether its services bring positive impacts to small-scale farmers.The results of the impact evaluation showed that crop insurance had a positive impact on rice farmers during the period of observation. It increased access to credit, smoothened consumption, and increased net income from rice production. The impact on income is particularly pronounced among smaller farms. It is recommended that PCIC should expand to small farm holders to maximize the benefits of the crop insurance program
Measuring adaptive capacity of farmers to climate change and variability: application of a composite index to an agricultural community in the Philippines
No full textFarming households in the Philippines are most vulnerable to climate change and variability due to their climate/weather-sensitive livelihood and lack of resources to finance adaptation measures. In order to formulate appropriate programs and policies addressing this vulnerability, it is essential to understand their adaptive capacity.
This study analyzed the adaptive capacity to climate change and vulnerability of 520 farming households in Dumangas, a town in central Philippines confronting climate/weather-induced risks. The Objectives were: to determine the levels of adaptive capacity of farming households to climate change, analyze the factors that cause the differences in adaptive capacity and find out whether adaptive capacity translates to adoption.
The level of adaptive capacity of each farming household was determined using a composite index based on previous studies. The index included five indicators namely human resources, physical resources, financial resources, information and diversity. Results showed that variations in adaptive capacity were caused by differences in information resources, physical and financial resources. Farming households that scored low in these three indicators had lower adaptive capacity. It was also found out that despite their level of adaptive capacity, households employed measures to adopt to climate change and variability. Households with higher adaptive capacity however employed more adaptation strategies
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
