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
Passaggio in Pakistan. L'immagine del bambino fra pressioni culturali e prospettive di globalizzazione
No full textTratteggiare nuovi sviluppi della pedagogia sociale, esplorare con uno sguardo pedagogico nuovi contesti, ed il contesto è sempre un contesto relazionale: è l’obiettivo da cui nasce questo volume.
In particolare, il volume presenta sette differenti contesti di apprendimento (sociale, culturale, simulato, scolastico, sportivo, virtuale, organizzativo), con un comune denominatore: l’attenzione verso il compito educativo che definisce l’ambito del possibile, della responsabilità personale e sociale. Questo lavoro a più mani, intende richiamare l’attenzione sull’inconfondibile esigenza d’interdisciplinarità della pedagogia sociale, sempre bisognosa di modelli euristici diversi che richiedono competenze distinte e complementari
[18F]FDG-PET-CT for early monitoring of tumor response: when and why.
No full text(18)F-fluorodeoxyglucose positron emission tomography ([(18)F]FDG PET) has been recognized as a suitable tool in tumor response assessment of patients complaining with solid tumors who have undergone chemo- and radiotherapy. It offers the advantage of functional tissue characterization, which is independent from morphologic criteria allowing to differentiate disease relapse from therapy-induced fibrosis. At present, there is a growing body of evidence that PET semi-quantitative assessment of treatment-induced changes in tumor [(18)F]FDG avidity may predict early tumor response and patient outcome. Patient management might be changed. For instance, in non responder patients this novel diagnostic approach would hamper useless ''wait and watch'' attitude in implementing further options or identifying those needing additional therapeutic strategies. On the other hand, for those patients revealing promptly a favourable metabolic response a cost-sparing approach could be implemented avoiding expensive diagnostic procedures during the follow-up as well as the risk of over-treating. In any case, since even a partial metabolic response may be an indication for continuing therapy, the advantage of metabolic assessment over conventional procedures may be clinically relevant. Although a morphological assessment has been considered for long time the standard for detecting therapy response, limitations of conventional computed tomography-based evaluation in solid tumors are well-known. PET provides an independent means of assessing malignancy. However, no consensus has been achieved until now regarding the optimal timing in performing PET during or at completion of treatment
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
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
Dynamization-induced nanosolutes (DINS) in ultra-dilute solutions Analysis on homeopathic dilute capsules below and over the Avogadro’s number
No full textBACKGROUND: Homeopathy is a controversial topic. It is not clear what is the role of the succussion that should in-crease the efficacy of the homeopathic remedy. The primary aim is to verify whether could be the presence of nanosolutes when the dilution increases past the Avogrado's number and whether the succussion process increases the presence of nanosolutes. The secondary goal is to provide a rational model to develop theories on the mechanism of action of these solutions from a clinical standpoint.METHODS: Three different solution lines of highly diluted solutions have been made for each active ingredient: the first line was a non-shaken solution, the other two lines were shaken. They have run the following measurements: Fluores-cence, Absorption, Dynamic Light Scattering, Microbiological analysis.RESULTS: Fluorescence, light scattering and absorption, did not show any difference between the samples containing only water and samples derived from the solutions containing the active ingredients The shaken dilutions have shown a higher content in bacteria than the corresponding non-shaken (Biesse Bioscreen measurement: 0.000 ANOVA and Bon-ferroni). The bacteria are largely gram-positive at difference with those presence in the reference water solution, that are largely gram-negative.CONCLUSIONS: This study allows highlighting the presence of nanosolutes in high-diluted solutions Such nanosolutes are bacteria, which would bond with parts of parent substance in clusters. The succussion increases the number of nano -solutes. It is possible to hypothesize a mechanism of action of the homeopathic remedy on microbiotic basis.(Cite this article as: Tramontana A, Nicolai E, Sorge R, Gaziano R, Marino D, Monteleone G, et al.
