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
Utilización de los servicios sanitarios en población infantil y adolescente europea
No full textLa utilització de serveis sanitaris en població infantil i adolescent europea ha estat fins ara poc analitzada. Aquest treball de recerca es va centrar en l'anàlisi de la utilització de serveis sanitaris en població infantil i adolescent de la ciutat de Barcelona i d'onze països europeus, estudiant la seva associació amb necessitats en salut, característiques de la família i dels sistemes sanitaris. Concretament, es van plantejar els objectius d'examinar la utilitat de la salut percebuda com a mesura de necessitat en salut i l'existència de desigualtats socials en la utilització de serveis sanitaris. Un objectiu addicional, a nivell metodològic, va ser estudiar la participació, resposta i representativitat de les mostres dels països participants en l'estudi europeu, segons els mètodes de selecció i d'administració. Es van utilitzar les dades de l'enquesta de salut de Barcelona (ESB) de l'any 2000 de la població de 5 a 14 any i de l'estudi europeu KIDSCREEN que es va dur a terme al 2003 en població de 8 a 18 anys. La utilització de serveis sanitaris en població infantil i adolescent va mostrar-se d'acord amb els nivells de necessitat en salut, excepte en l'accés davant dels problemes de salut mental. Es van trobar desigualtats socioeconòmiques i es van identificar característiques estructurals i organitzatives dels sistemes sanitaris que semblen disminuir l'accessibilitat. Les mesures de salut percebuda van aportar informació addicional confirmant la seva validesa i utilitat en l'avaluació de serveis sanitaris per a la població infantil i adolescent.La utilización de servicios sanitarios en población infantil y adolescente europea ha sido hasta ahora poco analizada. Este trabajo de investigación se dirigió a analizar la utilización de servicios sanitarios en población infantil y adolescente de la ciudad de Barcelona y de once países europeos estudiando su asociación con necesidades en salud y características de la familia y de los sistemas sanitarios. Específicamente, se plantearon los objetivos de examinar la utilidad de la salud percibida como medida de necesidad en salud y la existencia de desigualdades sociales en la utilización de servicios sanitarios. Un objetivo adicional, a nivel metodológico, fue estudiar la participación, respuesta y representatividad de las muestras de los países participantes en el estudio europeo, y compararlos según los métodos de selección y de administración. Se utilizaron los datos de la encuesta de salud de Barcelona (ESB) del año 2000 de la población de 5 a 14 años y del estudio europeo KIDSCREEN llevado a cabo en 2003 en población de 8 a 18 años. La utilización de servicios sanitarios resultó adecuada a los niveles de necesidad en salud, excepto en el acceso ante problemas de salud mental. Se encontraron desigualdades socioeconómicas y se identificaron características estructurales y organizativas de los sistemas sanitarios que parecen disminuir la accesibilidad. Las medidas de salud percibida aportaron información adicional confirmando su validez y utilidad en la evaluación de servicios sanitarios para la población infantil y adolescente.Analysis of the utilisation of health care services among children and adolescents at a European level has been scarce to date. This research aimed to analyse the use of health care services in children and adolescents in the city of Barcelona and eleven European countries and to examine the correlations between use of services and health needs, family characteristics, and healthcare system factors. More specific aims were to examine the utility of perceived health as a measure of needs and to determine whether there were social inequalities in the use of health care services. At a methodological level, a further objective was to examine the sampling and administration methods used in the European study in terms of participation, response rate, and representativeness and to compare them across countries. Data used were obtained from children aged 5-15 years included in the Barcelona Health Interview Survey (BHIS), which was carried out in 2000, and from children and adolescents aged 8-18 years included in the European KIDSCREEN study carried out in 2003. We found that use of services was generally in accordance with health needs, except for access for mental health problems. Socioeconomic inequalities were found, and structural characteristics of health care systems were identified as possible correlates of a reduced access to services. Measures of self-perceived health provided information which correlated with use of services, thereby confirming their validity and usefulness for health services research in child and adolescent populations.Programa de doctorat en Biomedicin
