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
Psychological characteristics of patients with chronic obstructive pulmonary disease and the change in the pulmonary rehabilitation program
No full textIntroductionThere is currently a paucity in the literature regarding the psychosocial aspects of Chronic ObstructivePulmonary Disease (COPD); this is associated with the limited number of parameters examined, butmainly with the lack of assessment of the effects of pulmonary rehabilitation programs on psychologicalsymptoms.Hypothesis-ObjectivesThe aim of this research was to investigate the psychological characteristics of Greek patients withCOPD, and to evaluate the potential changes in their psychological characteristics after attending apulmonary rehabilitation program. Essentially, we investigated two primary assumptions:*If patients with COPD have higher rates of psychopathology than the general population and*If the psychological symptoms associated with the disease can be modified through a pulmonaryrehabilitation program.Subjects and methodsThe study was conducted at the Pulmonary Rehabilitation Section of the Third Department ofPulmonary Medicine in "Sotiria" General Hospital of Athens in Greece, during the years 2008-2012.The study sample comprised of patients who had been diagnosed with COPD, uncomplicated by anyother chronic disease.We assessed psychological characteristics of patients upon enrollment and at completion of thispulmonary rehabilitation program.The total study sample comprised of 144 patients (112 men). 43 (29.9%) of them did notcomplete the rehabilitation program.The measurement of psychological and psychosocial characteristics of patients with COPD was doneusing self-report scales and questionnaires validated and standardized in the general population.More in detail, we used the following questionnaires:1. Beck's depression questionnaire (Beck Depression Inventory, BDI).2. Spielberger's anxiety questionnaire (STAI).3. The Toronto Alexithymia Scale Questionnaire (TAS-20).4. Antonovsky's Sense of Coherence questionnaire (SOC).5. The Family Support Scale (which was standardized in Greek population for the purposes of thisstudy).6. The Vital Exhaustion questionnaire (Maastricht questionnaire).7. A general psychopathology questionnaire (SCL-90R). The following parameters were recorded: gender, age, years of education, disease severity (asdetermined by pulmonary functions tests per GOLD consensus protocol) and disease duration.ResultsThe sample was not statistically different compared to the population of greek COPD patients regardinggender (x2> 0.05) and age (t-test p> 0.05).Initial evaluationThe average BDI score was significantly higher compared to the average BDI score in generalpopulation (11.61 versus 5.86, t-test p 0.05). Thus, all four groups were similarin severity of depression, anxiety, perception of family support, sense of coherence and vital exhaustion.There was no effect of FV1% upon Alexithymia, Vital Exhaustion, Depression, Anxiety, Sense ofCoherence (Pearson Correlation p> 0.05) whereas it showed a mild negative correlation with the senseof Family Support (Pearson Correlation p 0.05). Regardingthe percentage of patients who had depressive symptoms (BDI> 9) at baseline this was 47.5% (48patients) and finally 14.9% (15 patients), indicating a statistically significant reduction (x2 p 0.05); furthermore there were no differences between men andwomen (t-test p> 0.05).Regarding anxiety, we observed at baseline average scores higher than in the corresponding generalpopulation. Specifically, women had mean anxiety score of 42.62 (versus 37.47 in the general femalepopulation, t-test p 0.05). The percentage of women with clinically significant anxiety symptoms (STAI> 45) at baselinewas 47.6%, which dropped to 19% at the end of the program (x2 p 43) in the beginning of the program was25% and decreased to 12.5% (x2 p 0.05).In the final assessment statistically significant decreases were observed in vital exhaustion/alexithymiascores (paired t-test, p 0,05) και την ηλικία (T-test p>0,05).Αρχική Αξιολόγηση.Ο μέσος όρος στη BDI παρουσιάστηκε στατιστικά μεγαλύτερος έναντι του μέσου όρου που παρατηρείται στον γενικό πληθυσμό (11,61 έναντι 5,86 sample t-test p0,05). Δηλαδή και οι τέσσερεις ομάδες βαρύτητας είχαν παρόμοια κατάθλιψη, άγχος, οικογενειακή υποστήριξη, εσωτερική συγκρότηση και ενεργειακή εξάντληση.Από την εξέταση συσχετίσεων με Pearson Correlation δεν ανευρέθηκε συσχέτιση της FV1% με την Αλεξιθυμία, Ενεργειακή Εξάντληση, Κατάθλιψη, Άγχος, και Εσωτερική Συγκρότηση (PearsonCorrelation p>0,05). Αντίθετα ήπια αρνητική συσχέτιση παρουσίασε με την Οικογενειακή Υποστήριξη(Pearson Correlation p0.05). Ως προς το ποσοστό των ασθενών που παρουσίαζαν καταθλιπτική συμπτωματολογία (BDI > 9) στην αρχική μέτρηση ήταν 47.5% (48 ασθενείς) και στην τελική 14.9%(15 ασθενείς), μείωση στατιστικά σημαντική (x2 p0.05). Η μεταβολή στο άγχος δεν ήταν διαφορετική μεταξύ ανδρών και γυναικών (T-test p>0.05).Ως προς το άγχος, επίσης παρατηρήθηκαν κατά την αρχική μέτρηση μέσοι όροι μεγαλύτεροι των αντίστοιχων του γενικού πληθυσμού. Συγκεκριμένα, ο γυναικείος πληθυσμός του δείγματος παρουσίαζε μέσο όρο άγχους 42.62 (έναντι 37.47 του γενικού γυναικείου πληθυσμού, sample t-test p0.05). Το ποσοστό των γυναικών με κλινικά σημαντική αγχώδη συμπτωματολογία (STAI >45) στην αρχική μέτρηση ήταν 47.6%, ενώ στην τελική μειώθηκε στο 19% (x2 p43) κατά την έναρξη του προγράμματος ήταν 25% και μειώθηκε στο 12,5% (x2 p0.05).Στατιστικά σημαντική μείωση παρατηρήθηκε στην τελική αξιολόγηση τόσο στην κλίμακα ενεργειακής εξάντλησης όσο και στην κλίμακα αλεξιθυμίας (T test paired , p<0.5). Αντίθετα στατιστικά σημαντική αύξηση εμφανίστηκε στις κλίμακες εσωτερικής συγκρότησης και οικογενειακής υποστήριξης (T testpaired, p<0.5).Συμπεράσματα Ασθενείς με ΧΑΠ παρουσιάζουν μεγαλύτερες τιμές άγχους, κατάθλιψης και ενεργειακής εξάντλησης από το γενικό πληθυσμό. Μόνο το 44,4% του πληθυσμού δεν παρουσιάζει ψυχοπαθολογία. Κυριαρχεί η συμπτωματολογία κατάθλιψης, σωματοποίησης, ψυχαναγκασμών και άγχους. Μόνο το 25% των γυναικών δεν παρουσίασαν παθολογική ανύψωση σε κάποια παράμετρο έναντι 50% των ανδρών. Οι γυναίκες παρουσίασαν μεγαλύτερα ποσοστά στον ψυχαναγκασμό,στην κατάθλιψη και στο άγχος έναντι των ανδρών. Ως προς τα στάδια νόσου κατά GOLD δεν φαίνεται να παρουσιάζουν διαφορετικές τιμές στα ψυχολογικά χαρακτηριστικά. Ωστόσο η FEV1% εμφανίζει αρνητική συσχέτιση με την Οικογενειακή Υποστήριξη. Η Οικογενειακή Υποστήριξη και η Εσωτερική Συγκρότηση παρουσιάζουν αρνητική συσχέτιση με τις υπόλοιπες ψυχολογικές παραμέτρους και πιθανόν να δρουν προστατευτικά απέναντι στο άγχος και την κατάθλιψη. Σημαντικές μεταβολές παρουσιάστηκαν με τη λήξη του προγράμματος στις περισσότερες κλίμακες αλλά και στα παθολογικά ποσοστά. Μεγάλη μείωση παρατηρήθηκε σε: Κατάθλιψη, Άγχος, Ενεργειακή Εξάντληση. Αύξηση παρατηρήθηκε στην Οικογενειακή Υποστήριξη και Εσωτερική Συγκρότηση. Μείωση παρατηρήθηκε στα ποσοστά ψυχοπαθολογίας και στους μέσους όρους στις κλίμακέςτης SCL-90R με εξαίρεση τον Ψυχωτισμό και τον Παρανοειδή Ιδεασμό
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
