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
Familial risk for depression and anxiety:What can we learn from siblings?
Get PDFBackground Family history of affective disorders has long been recognized as one of the strongest risk factors for the onset and maintenance of the disorders. Familial risk for affective disorders represents an integration of an underlying genetic vulnerability and the familial clustering of unfavorable family circumstances in (early) life. In order to alleviate some of the burden that affective disorders are causing, it is necessary to better understand how the disorders and their associated features operate within families to increase psychopathology. This thesis extensively examined familial risk for affective disorders, with a broad focus on the role of genetic, clinical, and psychosocial vulnerability, and poor immunometabolic health. Methods Data came from the Netherlands Study of Depression and Anxiety (NESDA), an ongoing longitudinal cohort study (2004-present) on the long-term course and consequences of affective disorders. The baseline sample consisted of 2,981 participants (18-65 years), including 2,319 persons with a lifetime affective disorder and 652 healthy controls. Participants were assessed in face-to-face interviews at baseline and 2-, 4-, 6-, and 9-year follow-up. Among a broad range of demographic, psychiatric, genetic, and biopsychosocial measures, the 9-year follow-up included a detailed family history assessment; 1,425 lifetime affected NESDA participants had valid family history data. During the 9-year follow-up, full-biological siblings of NESDA participants with a lifetime affective disorder (i.e. ‘probands’) were additionally recruited to participate in the NESDA sibling study. This included a total of 380 siblings, related to 256 probands (N = 636 from 256 families). Discussion of main findings Lifetime affected patients with higher familial risk showed higher genetic vulnerability and a more unfavorable disease and psychosocial risk profile. Although a dichotomous family history measure is an informative indicator, familial risk for affective disorders seems to be better captured by a continuous score that incorporates family- and disorder-specific characteristics. Furthermore, prevalence of current (26.8%) and lifetime (50.3%) affective disorders in siblings of lifetime affected probands was substantial, and two- to three- times higher as compared to Dutch population frequencies. As compared to healthy controls without affected relatives, probands’ unaffected siblings showed enhanced social vulnerability and rumination. Despite this, the majority of affective symptoms and psychosocial vulnerabilities were, in fact, not elevated in unaffected siblings as compared to healthy controls, which may indicate their underlying resilience. Moreover, proband-sibling resemblance in affective symptoms, psychosocial vulnerability, and poor immunometabolic health was mild to moderate, indicating that these features, to a certain extent, cluster within families, but that lifetime affected patients and their siblings still show considerable individual differences despite their shared familial disposition. Finally, between siblings of the same at-risk family, cross-trait associations of affective symptoms appear to be relevant in the link with psychosocial vulnerability, but less in the link with poor immunometabolic health. Concluding remarks Findings illustrate that familial risk for affective disorders is a complex and dimensional construct that deserves attention in research and clinical practice. Having identified a wide variety of clinically-relevant factors that may explain heightened familial risk, the next generation of research should focus on preventing the onset of affective disorders and fostering resilience in at-risk relatives. Both within research and clinical practice, it is of particular importance to direct attention to family members when evaluating the risk for affective disorders, as this may contribute to a better understanding of the role of within-family processes in the etiology and maintenance of the disorders, and help identify pathways through which resilience is promoted. This knowledge may ultimately contribute to more effective treatment, the early identification of affective problems, and possibly preventing new onset of disorder, severe disability and intensive treatment in those at the highest risk
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.
