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
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
Modellierung des QoS-QoE-Zusammenhangs für mobile Dienste und empirische Bestimmung in einem Netzemulations-Testbed
Full text linkIn der theoretischen Auseinandersetzung mit mobilen Internet-Diensten sind Quality of Service (QoS) und Quality of Experience (QoE) als hochkomplexe und verbundene Konzepte zu erkennen. QoS umfasst dabei die technische Sicht auf das Telekommunikationsnetz, charakterisiert durch leistungsrelevante Parameterwerte (z. B. Durchsatz und Latenz). QoE hingegen bezieht sich auf die Bewertung des Nutzererlebnisses (z. B. Zufriedenheit und Akzeptanz). Zur gemeinsamen Erklärung bedarf es einer multi- bzw. interdisziplinären Betrachtung zwischen Ingenieurs- und Humanwissenschaften, da neben der Technik auch der Mensch als Nutzer in den QoS-QoE-Zusammenhang involviert ist.
Ein mehrschichtiges Modell erfasst die relevanten Einflussfaktoren und internen Zusammenhänge zwischen QoS und QoE sowohl aus Netz- als auch Nutzersicht. Zur Quantifizierung des Zusammenhangs konkreter Werte in einer empirischen QoE-Evaluation wurde ein umfangreiches psychophysikalisches Laborexperiment konzipiert. Das dafür entwickelte Netzemulations-Testbed erlaubt mobiltypische Netz- und Nutzungssituationen gezielt in einem Testparcours zusammenzubringen. Die formulierten Prinzipien zur Testrelevanz, -eignung und -effizienz berücksichtigen hierbei die Besonderheiten des Testaufbaus und -designs mit echten Endgeräten und Diensten.
Die Ergebnisse von über 200 Probanden bestätigen die vorhergesagten QoS-QoE-Charakteristiken der sechs untersuchten Dienste als kontinuierlich-elastisch bzw. sprunghaft-fest. Dienstspezifisch lässt sich jeweils von einem angestrebten Grad der Nutzerzufriedenheit auf die notwendigen Werte der QoS-Netzparameter schließen, woraus sich ein QoS-QoE-Zufriedenheitskorridor zwischen einem unteren und oberen Schwellwert ergibt. Teilweise sind dabei QoS-unabhängige Faktoren, z. B. die Art der Präsentation der Stimuli in der App auf dem Endgerät, als ebenso relevant zu erkennen wie die QoS-Netzparameter selbst.The thesis is centered on the relationship of Quality of Service (QoS) and Quality of Experience (QoE) for mobile Internet services. While QoS covers the technical view on the telecommunications network characterized by performance-related parameter values (e.g. throughput and latency), QoE refers to the assessment of the user experience (e.g. satisfaction and acceptability) in the use of the services. In the thesis QoS and QoE are revealed as highly complex and related concepts in theoretical contemplation. Integrating both concepts requires a multidisciplinary or interdisciplinary approach between engineering and human sciences to consider both - technological aspects of the network as well the human user. The designed multilayered model appropriately integrates the technical network view as well as the user's perspective by considering all relevant factors of influence and all internal relationships between QoS and QoE. The conducted extensive psychophysical laboratory experiment with real users, devices and services quantifies the relationship between specific QoS values and specific QoE values. A testbed developed for network emulation allows combining typical mobile network situations with typical usage situations in a controlled and focused manner. The three elaborated principles to test for relevance, suitability and efficiency take into account the special features of the test setup and test design. Test results gained from more than 200 volunteers confirm the predicted QoS-QoE-characteristics of the six tested mobile services to be either elastic or non-elastic. It is possible to conclude from the desired degree of user satisfaction on the necessary values of the QoS network parameters, which results in a QoS-QoE-corridor between lower and upper threshold values. Findings prove that QoS-independent factors, e.g. the type of presentation of the stimuli in the app on the user’s device, can be as relevant for QoE as the evaluated QoS network parameters themselves
