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
The Long Arm of Adversity: Examining the Role of Adverse Life Events on Mid- to Late-Life Cognitive Functioning
No full textAs the number of Americans living with Alzheimer’s disease and related dementias (AD/ADRD) continues to grow rapidly, there has been a concerted effort to better understand what potential modifiable risk factors account for ADRD across the life course. Despite the growing literature on modifiable risk factors for dementia, minimal research has focused on how exposure to adversity in early and midlife can affect cognitive functioning and dementia risk over the life course. More research is needed to identify how the long arm of adversity in childhood and adulthood affects cognitive functioning trajectories after age 50. The broad goal of this research is to examine the association between exposure to adverse life events in childhood and adulthood and cognitive functioning outcomes after age 50. This dissertation aims to (1) identify the relationship between household adverse childhood experiences (household ACEs) and mid- to late-life cognitive functioning, (2) identify the relationship between adverse adult experiences (AAEs) and cognitive functioning in mid-to late life over five waves of data (2010–2018), and (3) determine how the relationship between adverse life events (ALEs) in both childhood and adulthood impacts cognitive functioning over five waves of data (2010–2018).
Previous research has paid particular attention to how two of the three categories of ACEs (i.e., abuse and neglect) impact physical and mental health outcomes. Few studies have explored how a third category of ACEs—household dysfunction—impacts cognitive health in later life. In addition to the additive effect of exposure to household ACEs and AAEs on cognitive functioning after age 50. The outcomes examined in this research are two indicators of cognitive functioning: the Langa-Weir classification of cognitive function (i.e., normal; cognitively impaired, not dementia (CIND); and dementia) and total recall (indicator of cognitive decline). Longitudinal survey data is examined from the Health and Retirement Study (HRS) along with the 2018 tracker file; the Cross-Wave 2015–2017 Life History Mail Survey (LHMS): Harmonized and Aggregated Public Data Resource; the Cross-Wave Childhood Health and Family Aggregated Data; and the Langa-Weir Classification of Cognitive Function (1995–2018).
The empirical chapters use two statistical analysis approaches. Multinomial logistic regression is used to examine the relative risk for cognitive decline. Latent growth curve modeling is used to observe individual-level patterns of cognitive functioning trajectories and change over time. Results from the second chapter show that exposure to one household ACE was not statistically significantly associated with a higher relative risk for CIND, while exposure to two or more household ACEs was significantly associated with a higher relative risk for CIND. Exposure to one ACE and two or more household ACEs was significantly associated with a higher relative risk for dementia. The third chapter reports that exposure to one or more household ACEs is associated with statistically significantly lower cognitive functioning over an eight-year period (across five waves of data). As discussed in the fourth chapter, exposure to one or more AAEs is significantly associated with lower cognitive functioning over an eight-year period (across five waves of data). Exposure to one or more adverse life events (ALES) is associated with significantly lower cognitive functioning over an eight-year period (across five waves of data). Understanding how ALEs influence cognitive functioning over the life course can inform the development of interventions that could potentially mitigate this impact among individuals who have experienced ALEs.PhDHlth Svc Org & Plcy & Soc PhDUniversity of Michigan, Horace H.

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.
