    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    PDGFRA transcriptional regulation in human physiology and disease

    Contains fulltext : 30027.pdf (Publisher’s version ) (Open Access)Gene transcription is regulated by specific DNA sequences surrounding and within genes, so-called cis-acting factors, such as the promoter. Transcription factors or trans-acting factors, bind to these regulatory DNA elements in a sequence specific manner to influence the rate of transcription. Consequently, sequence variation in regulatory DNA elements, referred to as DNA polymorphisms, may alter protein binding and thus transcription of neighboring genes, and subsequently may also influence susceptibility to diseases. The gene encoding the platelet-derived growth factor receptor-alpha (PDGFRA) has been associated with a number of pathological conditions, such as neural tube defects (spina bifida) and various cancers including gliomas. The studies described in this thesis were undertaken to identify both cis- and trans-acting factors that regulate PDGFRA transcription and to determine their involvement in gliomas and NTDs. We identified ten polymorphisms in the human PDGFRA promoter, which together form five haplotypes: H1, H2alpha, H2beta, H2gamma and H2delta, of which H1and H2alpha are the most common. H1 mediates low, while H2alpha mediates high transcriptional activity. Our results indicate that this difference in activity can partly be regulated at the epigenetic level. From several case-control studies it appeared the low activity haplotype H1 was overrepresented in spina bifida cases, while it was underrepresented in glioblastoma cases. This suggests that low PDGFRA expression predisposes to neural tube defects, while at the same time protecting against gliomas. Furthermore, PDGFRA haplotypes appeared to differentially interact with maternal nutritional factors in predisposition to spina bifida, and also affected body growth. Finally, we identified a number of PDGFRA upstream regulators, some of which themselves have been directly associated with NTDsRadboud University, Cell Biology, 22 mei 2007Promotor : Zoelen, E.J.J. van132 p

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    We 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

    El presente informe de investigación surgió de la necesidad de analizar la coordinación óculomanual en los niños de seis años de edad, por lo tanto el problema investigado fue: ¿Cuál es el diagnóstico de la coordinación óculo- manual en niños del primer grado de la I.E. N° 30027 "San Sebastián" La Punta - Huancayo? El objetivo logrado: Diagnosticar la coordinación óculo- manual en niños del primer grado de la I.E. N° 30027 "San Sebastián" La Punta - Sapallanga. · La investigación es de tipo básica, arribando al nivel descriptivo. El método que acompañó desde el inicio al fmal del estudio fue el método científico; el método aplicado en la investigación es el método descriptivo. El diseño que guío la investigación es descriptivo simple con muestra- observación con un solo grupo. La muestra fue no probabilística y estuvo constituida por 22 estudiantes de primer grado "A" de primaria. La técnica para recopilar datos fue la observación, cuyo instrumento es la ficha de observación. Para el procesamiento de datos se aplicó la estadística descriptiva, se desarrolló durante el año 2014 y 2015. Arribando a la siguiente conclusión: A consecuencia de los resultados obtenidos por la ficha de observación podemos decir que el diagnóstico de la coordinación óculo - manual en los niños del primer grado "A" de la Institución Educativa N° 30027 "San Sebastián" de la Punta- Sapallanga, tienen una buena coordinación óculo - manual en su mayoría de estudiantes, puesto que existe un mínimo de estudiantes conformada por cinco estudiantes del total de 22 niños que tienen dificultades en la coordinación óculo - manual.Tesi

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We 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
