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
Should we respect parents' views about which results to return from genomic sequencing?
No full textGenomic sequencing (GS) is now well embedded in clinical practice. However, guidelines issued by professional bodies disagree about whether unsolicited findings (UF)-i.e., disease-causing changes found in the DNA unrelated to the reason for testing-should be reported if they are identified inadvertently during data analysis. This extends to a lack of clarity regarding parents' ability to decide about receiving UF for their children. To address this, I use an ethical framework, the Zone of Parental Discretion (ZPD), to consider which UF parents should be allowed to choose (not) to receive and examine how well this assessment aligns with existing professional recommendations. Assessment of guidelines shows recommendations ranging from leaving the decision to the discretion of laboratories through to mandatory reporting for UF for childhood onset, treatable/preventable conditions. The ZPD suggests that parents' decisions should be respected, even where there is no expected benefit, provided that there is not sufficient evidence of serious harm. Using this lens, parents should be able to choose whether or not to know UF for adult-onset conditions in their children, but only insofar as there is insufficient evidence that this knowledge will cause harm or benefit. In contrast, parents should not be allowed to refuse receiving UF for childhood-onset medically actionable conditions. The ZPD is a helpful tool for assessing where it is appropriate to offer parents the choice of receiving UF for their children. This has implications for refinement of policy and laboratory reporting practices, development of consent forms, and genetic counselling practice.sponsorship: Danya Vears acknowledges the infrastructure funding received from the Victorian State Government through the Operational Infrastructure Support (OIS) Program and would like to thank Prof Lynn Gillam for her feedback on the manuscript.

Healthcare professionals’ perspectives on and experiences with non-invasive prenatal testing: a systematic review
No full textBACKGROUND: The increasing integration of non-invasive prenatal testing (NIPT) into antenatal practice and public healthcare systems globally raises both significant challenges in standardising service delivery and important ethical questions around routinisation and reproductive autonomy. This systematic review aims to synthesise existing primary empirical research on healthcare professionals' views on and experiences with NIPT. METHODS: A systematic search was conducted across four major databases in September 2023 and repeated in December 2024. Studies that reported findings from primary empirical research, including quantitative, qualitative and mixed methods research were included. RESULTS: Searches returned 65 eligible articles, spanning 38 countries and 1 special administrative region and at least 12 professions. Views on who NIPT should have access to and which conditions should be screened for were influenced by perceived clinical utility. While healthcare professionals acknowledged NIPT as beneficial for supporting reproductive autonomy, concerns were raised about the amount and complexity of information to be conveyed during prenatal counseling and potential pressure to test. Cost was also identified as a significant barrier. Challenges reported during post-test counseling included communicating test failures and gaining information from laboratories. Views on the implications of NIPT for decision-making around abortion and for people with disabilities varied. CONCLUSIONS: Healthcare professionals play a critical role in facilitating the access to and decisions by pregnant people around prenatal genetic testing. Addressing barriers in clinical practice and increasing consistency across and access to clinical guidelines and education resources may support healthcare professionals in supporting reproductive autonomy
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
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
