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
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
Documenting Women’s Experiences Obtaining Abortion Services While Residing In Yukon Territory
No full textAlthough abortion has been decriminalized in Canada since 1988 and is covered as a medically necessary service through territorial health insurance schemes, anecdotal evidence suggests women in Canada’s north face significant barriers to accessing care. With a population of fewer than 34,000 spread across an area that is larger than California, geographic remoteness impacts health care access and quality in Yukon Territory. This qualitative study aimed to explore the dynamics shaping access to abortion care in the Yukon, provide an opportunity for women to share their experiences, and identify possible avenues for improving service delivery. In 2015-2016, the study team conducted 16 in-depth interviews with women and 11 key informant interviews. We used an iterative analytic approach allowing for the identification of emerging codes and themes. Our findings reveal that women face a number of barriers when accessing abortion services in Yukon. Specifically, a physician referral is required, as are several pre-procedure appointments, with no one central location to obtain these services. Women expressed concerns of privacy, overcoming logistical constraints, lengthy wait times, and lack of follow-up supports. Challenges were further amplified for women residing outside of Whitehorse, the sole location to obtain abortion services in the territory. Facilitating efforts to create a more transparent and streamlined service would ease the process for women seeking care and appears warranted. The recent registration of mifepristone could serve to alleviate certain barriers, presuming that the approved regimen is affordable, evidence-based, and available at more service delivery points.\ud

Bien que l'avortement a été décriminalisé au Canada depuis 1988 et est couvert en tant que service médicalement essentiel par le biais des régimes d'assurance-santé territoriales, des évidences non confirmées suggèrent que les femmes vivant au Nord du Canada font face à des obstacles importants quant à l'accès aux soins. Avec une population de moins de 34,000 habitants répartit sur un territoire d’une superficie supérieure à celle de la Californie, les effets de l’éloignement géographique sur l'accès et la qualité des soins de santé dans le territoire du Yukon sont considérables. Cette étude qualitative visait à explorer la dynamique qui façonne l'accès aux services d'avortement au Yukon, fournir une occasion pour ces femmes de partager leurs expériences et d'identifier les alternatives possibles pour améliorer la prestation de ces services. En 2016-2016, l’equipe de recherche a effectué 16 entrevues avec des femmes et 11 entrevues avec des informateurs/acteurs clés, et avons utilisé une approche analytique itérative permettant l'identification d’une codification et des thèmes émergents. Nos résultats démontrent que les femmes font face à un certain nombre d'obstacles lors de l'accès aux services d'avortement au Yukon. En effet, une recommandation médicale est requise, de même que plusieurs rendez-vous pré-procédure et un manque de services centralisés. Les atteintes à la vie privée, les contraintes logistiques, les longs temps d’attente et le manque de suivi sont des contraintes exprimées par nos participantes. Ces défis sont encore plus important pour les femmes habitant à l'extérieur de Whitehorse qui est le seul endroit pour obtenir des services d'avortement sur le territoire. Promouvoir les efforts visant à créer des services plus transparents et simplifiés faciliteraient le processus pour les femmes qui requiert des soins et semblent nécessaires. La récente introduction de la mifépristone pourrait alléger certains obstacles, en supposant que le médicament adopté est abordable, fondé sur des preuves scientifiques, et disponible à plusieurs points de services
How Might Canadian Women Talk About Peri-Coital Contraception?
No full textThe peri-coital contraceptive pill is a potential method for pregnancy prevention that could be taken in a period before or after unprotected sexual intercourse. However, uptake of a new contraceptive method relies on accessible terminology and frameworks with which to discuss it. I conducted seven focus group discussions across Canada to understand how women talk about different reproductive health technologies, explore the ways these discourses influence language and frameworks women use to talk about peri-coital contraceptives, and identify perceptions of and concerns about this potential method. Women thought the peri-coital contraceptive pill would be a valuable addition to current contraception. They disliked the name ”peri-coital”; although some participants created more resonant names related to unique aspects of this method, many found it challenging to clearly discuss the method with existing language for contraception. Concerted effort to develop terminology that is clearer may help facilitate the eventual introduction of this new contraceptive method in Canada and beyond
