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
Patienters upplevelser av att drabbas av en vårdskada
No full textI Sverige drabbas cirka 100 000 patienter varje år av en vårdskada. En vårdskada innebär ett onödigt lidande för patienten då händelsen kunde ha undvikits om adekvata förebyggande åtgärder hade satts in. En vanligt förkommande vårdskada är en vårdrelaterad infektion. Att skadas av hälso- sjukvården innebär att ett vårdlidande uppstår. Många patienter lider i onödan då vårdarna inte har tillräcklig kunskap om problemet för att kunna möta patienterna i den uppkomna situationen.Syftet med litteraturstudien var att beskriva patienters upplevelser av att drabbas av en vårdskada. Elva kvalitativa artiklar granskades och ett resultat med fyra huvudteman och tillhörande subteman utarbetades.Resultatet visar att patienter som drabbats av en vårdskada upplevde en mängd starka känslor och situationer under den tid som följde efter vårdskadan. Patienterna upplevde sig stigmatiserade och uteslutna från vården. De kämpade för att återfå sitt oberoende.Till stor del var en vårdskada en traumatisk negativ upplevelse. För att hantera den uppkomna situationen behövde patienterna känna att de behandlades med respekt och ärlighet. Det var betydelsefullt att få information och kunskap för att kunna känna trygghet. Patienterna upplevde att tilliten till sjukvården raserades då vårdskadan hade inträffat. Då en vårdskada inträffat måste vårdarna gör allt för att möta patienterna med ärlighet, öppenhet och god kommunikation. Om patienterna känner att vårdarna finns till för dem kan lidandet minska och förtroendet för vården kan börja återuppbyggas på nytt.Program: Fristående kur
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
Health, well-being, and outcomes after aortic valve replacement
No full textBackground: Aortic stenosis is the most common heart valve disease requiring intervention. Without aortic valve replacement, the mortality is approximately 50% within 2 years after onset of severe symptoms.
Aim: To explore factors influencing patients’ motivation to undergo aortic valve replacement, and to study associations between social factors and mortality risk, and associations between preoperative frailty and health-related quality of life, before and after aortic valve replacement.
Methods: This thesis comprises one qualitative study, three registry-based observational studies and one questionnaire-based study on patient reported outcome measures. Paper I explored 18 patients’ motivation to undergo transcatheter aortic valve implantation (TAVI). Paper II explored associations between income, education, marital status, and long-term mortality risk in 14,537 patients who had undergone surgical aortic valve replacement (SAVR). Paper III explored the association between marital status, educational level, and mortality risk in 5,924 TAVI patients. Paper IV assessed the risk of all-cause mortality in 5,924 TAVI patients compared to 10,928 age- and sex-matched controls who had not undergone TAVI. Paper V compared changes in health-related quality of life (HRQoL) in relation to preoperative frailty level in 209 TAVI patients.
Results: Patients’ motivations to undergo TAVI were driven by a longing to have a few more good years and to be independent of others. Survival after SAVR was three years shorter in patients with the lowest socioeconomic status compared to those with the highest. Never having been married and low education were associated with an increased mortality risk after both SAVR and TAVI. Low income was associated with an increased mortality risk after SAVR. Patients who underwent TAVI had a lower adjusted risk of mid-term mortality compared to age- and sex-matched individuals from the general population. TAVI patients’ HRQoL improved one year after TAVI independently of the preoperative frailty level.
Conclusions: Patients’ motivation to undergo TAVI was strongly linked to their hopes of restoring well-being. Social factors are associated with increased morbidity and mortality after aortic valve replacement. TAVI is associated with longer adjusted survival. Improvements in HRQoL after TAVI is independent of preoperative frailty level
