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
Shape (of) your Job – Extending Job Crafting Theories by the Examination of Curvilinear and Reciprocal Relationships and the Assessment of a New Conceptualization
Full text linkJob Crafting – durch Beschäftigte initiierte Veränderungen des Jobs – hat in der Wissenschaft und Praxis in den letzten Jahren einen hohen Stellenwert eingenommen. Die Job Crafting Literatur hebt besonders die positive Seite des Job Craftings hervor – sowohl auf inter- als auch intraindividueller Ebene. Allerdings scheinen Job Crafting und seine Folgen komplexer zu sein und benötigen ein besseres Verständnis. Daher war das Ziel der Dissertation bisherige Job Crafting Theorien anhand von drei Ansätzen zu erweitern. Dafür habe ich vier Studien durchgeführt, aus denen drei Manuskripte hervorgingen. Erstens, in Studie 1 bezog ich mich auf die ressourcen-konsumierende Natur des Job Craftings und fand einen kurvilinearen Job Crafting-Effekt auf das Arbeitsengagement. Dies galt nur für erschöpfte Beschäftigte (d.h. Moderationseffekt). Zweitens, Studie 2 fokussierte sich auf den fluktuierenden Anteil des Job Craftings innerhalb von Beschäftigten (d.h. intraindividuelle Ebene) und untersuchte reziproke Beziehungen zwischen Job Crafting, Arbeitsengagement und Leistung von einer zur nächsten Woche. Daten aus einer wöchentlichen Tagebuchstudie wurden mit Hilfe eines Random-Intercept Cross-Lagged Panel Modells (RI-CLPM) analysiert. Es gab keine reziproken Beziehungen zwischen Job Crafting, Arbeitsengagement und Leistung auf intraindividueller Ebene zwischen den Wochen, die Beziehungen waren sehr heterogen. Drittens, in Studien 3 und 4 haben wir die Approach-Avoidance Job Crafting Skala basierend auf dem Approach-Avoidance Crafting Model entwickelt und validiert. Die Skala bildet Approach und Avoidance Crafting als unabhängige Faktoren ab und misst 8 verschiedene Dimensionen resultierend aus einer hierarchischen Struktur, die frühere Job Crafting Konzepte integriert. Unsere Ergebnisse zeigten inkrementelle Validität von Approach und Avoidance Crafting bei der Vorhersage von arbeitsbezogenen Outcomes.Job crafting – employee-initiated changes to the job – has received a high priority in science and practice in the recent years. Job crafting literature often emphasizes its positive effects – both at the between-person and within-person level. However, job crafting and its consequences seem to be more complex and, thus needs further understanding. Doing so, the aim of the dissertation was to expand current job crafting theories by using three approaches. Therefore, I conducted four studies resulting in three manuscripts. Firstly, in Study 1, I referred to the resource-consuming nature of job crafting and found a curvilinear effect (U-shaped curve) of the job crafting strategy crafting social resources (i.e., increasing social resources) on work engagement. This only applied to exhausted employees (i.e., a moderation effect). Secondly, in Study 2 focused on the fluctuating portion of job crafting within employees and investigated reciprocal relationships between job crafting, work engagement, and performance from one week to the next at the within-person level. Data from a weekly diary study were analyzed with a random-intercept cross-lagged panel model (RI-CLPM). There were no reciprocal relationships between job crafting, work engagement, and performance at the within-person level across weeks, rather the relations were more heterogeneous than anticipated. Thirdly, in Study 3 and 4, we developed and validated the Approach-Avoidance Job Crafting Scale based on my approach-avoidance crafting model. The scale depicts approach and avoidance crafting as two independent factors and assesses eight different job crafting dimensions. These result from a hierarchical structure in which previous job crafting concepts are integrated. Our results showed that approach and avoidance crafting have incremental validity in predicting work-related outcomes beyond previous job crafting scales
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

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.
