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
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

Adult experiences of life changes in obesity : A litterature review
No full textBakgrund Övervikt och fetma är ett stort folkhälsoproblem som kan orsaka olika sjukdomar. Dessutom leder övervikt och fetma till minskad autonomi och nedsatt arbetsförmåga som förorsakar stora samhälleliga kostnader för samhället. Sjuksköterskans ansvarar är att hjälpa personer med övervikt och fetma förändra sina ohälsosamma levnadsvanor, förebygga ohälsa, få kunskap om egenvård samt stöd och hjälp vilket är väsentligt och avgörande under livsstilsförändringar. Syfte Syftet var att beskriva vuxna personers upplevelser av livsstilsförändringar vid fetma Metod En litteraturöversikt med nio vetenskapliga varav åtta var kvalitativa, en kvantitativ genomfördes enligt Fribergs metodbeskrivning. Databaserna Cinahl Complete och PubMed användes för att söka fram artiklarna som analyserades och tematiserades under olika rubriker enligt Fribergs metod. Resultat Två huvudteman identifierades i resultatet: Upplevda hinder och utmaningar för livsstilsförändringar samt Underlättande och stödjande vid livsstilsförändringar. Under första temat identifierades två undertemat Oförmåga samt Psykisk lidande. Under andra temat identifierades två underteman, Stöd av andra samt Acceptans och Mindfullnessövningar Slutsats Resultatet i denna litteraturöversikt visade att personer som hade övervikt och fetma behövde vårdpersonalens stöd och hjälp för att förbättra sina levnadsvanor, förstärka sin autonomi och genomföra egenvårdsinsatser för att uppnå hälsosammare livstillförändringar.Background Overweight and obesity are a major public health problem that can cause various diseases. Moreover, overweight and obesity could lead to reduced autonomy and impaired working ability, which cause large social costs for society. The nurse`s responsibility is to help people with overweight and obesity to change their lifestyles, prevent ill-health, gain knowledge about self-care as well as support and help, which is essential and decisive during life changes. Aim The aim was to describe the experiences of adult's lifestyle changes in obesity. Method A literature review with nine scientific articles, eight which were qualitative, one quantitative, was carried out according to Friberg`s method description. The databases Cinahl Complete and Pubmed were used to search for the articles that were analyzed and thematized under different headings according to Friberg`s method. Results Two main themes were identified in the results: Perceived obstacles and challenges for lifestyle changes and facilitating and supporting lifestyle changes. Under the first theme, two sub-themes Inability and Mental suffering were identified. Under the second theme, two subthemes were identified, Support from others and Acceptance and Mindfulness exercises. Conclusion The results of this literature review showed that people who were overweight and obese needed the support and help of healthcare professionals to improve their lifestyle habits, strengthen their autonomy and implement self-care efforts to achieve healthier lifestyle changes
