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
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
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
Large-scale high-quality surveys without field interviewers in the UK: an evidence review
No full textRelevance & research question: data collection organisations are shifting toward new approaches, with social surveys undergoing significant design and implementation changes. Since the COVID-19 pandemic, agencies have increasingly moved to online data collection due to dwindling response rates and rising fieldwork costs. A key challenge for self-completion general population surveys is the absence of field interviewers to facilitate recruitment and participant retention. This research examines the UK survey landscape, aiming to identify recruitment methods for self-administered surveys, that can produce more representative samples of the general population.Methods & data: we present findings from an information request sent to the UK’s nine most important survey agencies. We collected information on surveys without field interviewers conducted between 2018 and early 2024, including publicly available technical and methodological reports and other survey materials, along with internal reports provided by the agencies. We processed and codified this information, building a spreadsheet containing 144 instances of 59 longitudinal and cross-sectional surveys, along with 227 communication materials. Results: the responses for the surveys in our dataset use 57% online, 38% paper, and 5% telephone modes. Most surveys (84%) offer incentives to participants, with 92% being monetary and only 33% given unconditionally. Response rates vary widely – household-based cross-sectional surveys tend to have lower response rates (81% at 30% response or lower) than individual-based ones (47% at 30% or lower). Longitudinal surveys generally have the highest response rates. While only 35% of reports assess sample representativeness, the general trend confirms that mixed-mode surveys yield more representative samples than single-mode surveys.Added value: to our knowledge, this review is the first coordinated effort to collate and summarise recruitment strategies for surveys without field interviewers in the UK. It covers sampling design, communication strategies and materials, incentivisation, fieldwork procedures, response rates, and report quality assessments. Our dataset provides insights into the current state of survey practice and helps identifying practices that might contribute towards higher response rates and sample representativeness.<br/

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
