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
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
Anwendung der peripheren elektrischen Stimulation bei Gesunden und Schlaganfallpatienten und die Auswirkungen auf die somatosensorisch evozierten Potenziale
Full text linkNur wenige Studien haben die somatosensorisch evozierte Potenziale (SEP) genutzt, um die kortikale Neuroplastizität und die Rehabilitationsprognose bei Schlaganfallpatienten nach der Anwendung der funktionellen Elektrostimulation (FES) zu untersuchen. Das Hauptziel meiner Studie war es, systematisch zu überprüfen, ob FES eine Rolle bei der Veränderung der Latenzen und Amplituden von SEPs bei gesunden Probanden oder bei den Patienten nach einem Schlaganfall darstellt. Weiterhin suchte ich nach einer Korrelation zwischen sensorischen und motorischen Funktionstests und den Veränderungen der SEP-Latenzen und Amplituden. Folgende Datenbanken wurden durch-sucht: Pubmed/MEDLINE, Scopus/ScienceDirect, Web of Science/Clarivate, Cochrane Library, The Physiotherapy Evidence Database (PEDro), und Clini-calTrials.gov. Die Titel und Abstracts sowie die Volltexte der Studien wurden von zwei unabhängigen Autoren anhand von im Vorfeld festgelegten Kriterien auf ihre Eignung geprüft. Es wurden alle Studien, die sich auf die Behandlung der oberen oder unteren Extremitäten oder des Rumpfes mit FES, inkludiert. Die systematische Suche resultierte in insgesamt 11344 Studien, von denen nur 10 evaluiert wurden. Ich konnte keinen ausreichenden Nachweis finden, dass das SEP als Indikator für eine Prognose der Rehabilitation nach einem Schlaganfall nützlich ist. Ich fand jedoch einen Zusammenhang zwischen verschiedenen sensorischen und motorischen Funktionsbewertungen und Veränderungen der SEP-Komponenten. Die Schlaganfallstudien mit FES, die eine willkürliche Kontraktion für eine bestimmte Bewegung oder Aufgabe initiieren, deuten auf eine positive Beziehung und Korrelation mit den Bewertungen der motorischen Funktion hin. Es könnte darauf hinweisen, dass FES eine positive Auswirkung auf die sensorische Reorganisation hat, was sich in der Veränderung der SEP-Amplitude und -Latenz widerspiegelt. Das Ausmaß der Konnektivität zwischen SEP und kortikaler Plastizität lässt sich bisher nicht feststellen. Um diese Hypothese zu bestätigen, haben wir ein randomisiertes, kontrolliertes zwei-Perioden-Crossover-Design mit gesunden Probanden und Schlaganfallpatienten durchgeführt. Meine zweite Studie analysierte Veränderungen der pathologischen SEP-Latenzen und Amplituden nach einem akuten Schlaganfall nach zweiwöchiger Rehabilitation mit FES. Die Veränderungen der SEPs wurden auch mit der FES-Intervention bei Schlaganfall-Symptomen der Fußheberschwäche (FHS) korreliert, die anhand des 10-Meter-Gehtests und der Stärke der Dorsalflexion im Fußgelenk bewertet wurden. Gruppe A erhielt die FES direkt, während Gruppe B nach zwei Wochen behandelt wurde. Zudem wurden in der unbehandelten Kontrollgruppe gesunder Erwachsener in den gleichen Zeitabständen wie bei den Schlaganfallpatienten wiederholte SEP-Messungen durchgeführt. Die statistische Analyse (ANOVA) zeigte eine signifikante Abnahme der SEP-Latenzen des paretischen Nervus tibialis (NT) in den Schlaganfallgruppen nach der Intervention, gefolgt von einer Abnahme der SEP des nicht-paretischen NT im Vergleich zur Kontrollgruppe der gesunden Erwachsenen. Darüber hinaus wurde in den Schlaganfallgruppen eine Zunahme der Kraft des FHS und eine Verringerung der Kadenz beobachtet. Wir fanden eine moderate Korrelation (r=0,50-0,70) zwischen der Latenzzeit des nicht-paretischen NT und der Schrittkadenz in den Schlaganfallgruppen nach der FES-Zeit. Der pathologische Gang wurde verändert und das afferente SEP-Feedback verbesserte sich nach der FES-Intervention.A small number of studies used somatosensory evoked potentials (SEP) to demonstrate changes in cortical sensory function in healthy subjects or to assess cortical plasticity and rehabilitation prognosis in stroke patients following an functional electrical stimulation (FES) intervention. The main objective of first study was to systematically investigate whether FES is involved in altering SEP latency and amplitude in healthy subjects and stroke survivors. We also searched for correlations between sensory and motor assessments and SEP component changes in the included studies. Databases of interest were: Sco-pus (ScienceDirect), Pubmed (MEDLINE), Web of Science, The Physiotherapy Evidence Database (PEDro), Cochrane Library, and ClinicalTrials.gov. A priori eligibility criteria were used to screen titles, abstracts, and reports for eligibility. There were no limitations regarding the treatment of the upper extremity, lower extremity, or trunk with FES. The last systematic search resulted in 11344 entries. However, only ten of these were evaluated. There was insufficient evidence for using SEP to predict rehabilitation prognosis after stroke. However, we did find a correlation linking the assessment of sensory and motor function and the changes in the components of the SEPs. Moreover, a positive relationship and correlation with motor function assessments in stroke studies using FES, which initiates a voluntary contraction used for a specific movement or task, was found. However, the degree of connectivity between the SEP and cortical plasticity remains elusive. To confirm this hypothesis, we conducted a randomised, controlled, two-period crossover study with stroke patients and healthy volunteers. The second study examined changes in pathological SEP latencies and amplitudes following an acute stroke after two weeks of rehabilitation with FES. Changes in SEPs between the stroke groups were also correlated with FES therapy intervention for foot drop stroke symptoms, assessed by the 10-metre walk test and strength of dorsal flexion in the foot ankle. Group A received the FES directly, while group B was treated after two weeks. Moreover, repeated SEP measurements were evaluated in the untreated control group of healthy adults at the same interval as for stroke groups. The statistical measures (ANOVA) showed a significance decrease in paretic tibial nerve SEP latencies in stroke groups after the intervention, tracked by a decrease in non-paretic tibial nerve SEP comparing to the control group of healthy adults. Furthermore, increasing of foot drop strength and reducing the cadence in stroke groups was found. We found a moderate correlation (r=0.50-0.70) between non-paretic tibial nerve latency N50 and step cadence in stroke groups after the FES time. The pathological gait was modified with improved SEP afferent feedback following the FES intervention
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.
