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
Epigenetic regulation of tumor growth: micro RNA as biomarkers and possible new drugs
No full textMicro RNAs are single stranded non-coding RNAs of about 15-23 in lenght that regulate gene expression at the post-transcriptional level. Many of the miRNAs idetified to date are aberrantly expressed in a broad range of different cancer types, indicating that they can function as conventional tumour suppressor and/or oncogenes. The ability to repress many oncogenes at once and across different oncogenic pathways and the ability of miRNAs to circulate in biologic fluids caried by proteins, lipids and exosomes provides a strong rationale for developing miRNA-based cancer therapies
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
Ruolo della microscopia laser confocale nella diagnosi e follow-up delle patologie dei capelli e del cuoio capelluto
Full text linkLe patologie dei capelli e del cuoio capelluto sono molto frequenti, possono essere difficili da diagnosticare e spesso costituiscono la proiezione di patologie sistemiche o disagi psicologici. Pertanto, per un corretto inquadramento diagnostico, è necessario talvolta ricorrere all’esecuzione di una biopsia, una procedura chirurgica invasiva che esita in una piccola cicatrice e che spesso viene percepita con disagio dal paziente. In tale contesto, la microscopia laser confocale (Reflectance Confocal Microscopy or RCM), una tecnica diagnostica non invasiva che produce immagini tessutali in vivo con una risoluzione quasi come istologica (biopsia ottica), risulta di particolare interesse. L’RCM impiega un raggio laser a bassa potenza (830 nm, vicino all’infrarosso) che scansiona la cute orizzontalmente producendo dettagliate immagini in bianco e nero, dall’epidermide al derma papillare superiore con uno spessore che arriva fino a 200-300 μm. Pertanto, l’RCM consente di valutare i cambiamenti morfologici che avvengono nei pazienti affetti da patologie dei capelli e del cuoio capelluto e di individuare rapidamente le caratteristiche distintive di tali disordini, permettendo di giungere rapidamente ad una corretta diagnosi. Quindi, grazie all’utilizzo di tale strumento è possibile ridurre il numero delle biopsie effettuate a scopo diagnostico e, quando tale procedura risulta comunque necessaria, l’RCM risulta d’ausilio nella scelta del sito più significativo su cui eseguirla. Infine, l’RCM risulta particolarmente utile nel valutare la risposta terapeutica, consentendo durante il follow-up di individuare precocemente una possibile riattivazione o recidiva di malattia
