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
Health Care Transitions in Sickle Cell Disease
No full textOver the past three decades, advances in the care for children with sickle cell disease (SCD) have increased their life expectancy and necessitated their transition to adult health care. However, there is a limited understating of health care transition in SCD and the impact it has on outcomes beyond perspective on and satisfaction with the process from the perspective of the adolescent and young adult (AYA) and their families. The purpose of this dissertation was to provide a better understanding of health care transitions in AYAs with SCD. This purpose was achieved through an examination of the state of the science on health care transition in AYAs with SCD, the challenges of shifting self-management from the parent to the adolescents with SCD prior to transition to adult care, and the patterns of health care utilization during transition and the factors associated with these patterns.Findings from our integrative review indicated that few studies examined health care transition in AYAs with SCD. Most of the research on health care transition in AYAs with SCD focused on individual, family support, and the health care domain, yet results are inconclusive. For example, there is evidence that parents were heavily involved in the AYA’s health care. Although this involvement was viewed as supportive by the AYA as well health care providers, it’s not clear how parental involvement and the parent-AYA relationship can be utilized to facilitate health care transition for the AYAs with SCD. In addition, very few studies examined health care transition outcomes or examined how AYAs utilize the health care system to meet their health care needs during transition. To further understand the parent-AYA relationship in managing SCD, we examined the shifting of management responsibility from the parent to the adolescent with SCD. Our findings indicated that shifting management responsibility is a critical and challenging process. The challenges that adolescents and parents face are adaptive-type challenges, rather than technical-type challenges. While technical-type challenges are easily fixed with technical work, more complex adaptive work is needed to address adaptive-type challenges, making the shifting of management responsibility more complex.To understand health care transition in AYAs with SCD, we conducted a longitudinal examination of health care utilization for AYAs with SCD during transition to adult care and examined the factors associated with the different trajectory groups. Most AYAs in our sample had low clinic, hospital, and emergency department (ED) utilization trajectories. Few AYAs had high utilization in the clinic, hospital, and/ or ED. However, this group usually accounts for the highest costs of care. The sample mean emergency reliance scores were also below the cutoff point of 0.33 for high ED reliance. However, we did find evidence of increasing reliance on the ED compared to ambulatory care with increasing age indicating that a small group of AYAs with SCD might be at increased risk for high reliance on the ED. Individual, contextual, and transfer related factors were associated with the different health care utilization trajectory groups for AYAs with SCD. These factors varied between the different health care services indicating the complexity of health care utilization in AYAs with SCD and the factors influencing them. Receiving hydroxyurea was the only common predictor between higher clinic and higher hospital utilization trajectory groups, while distance to the sickle cell center was the only common predictor between higher clinic and higher ED utilization trajectory groups. Depression, chronic pain, long-acting narcotics, and chronic transfusion at age 19 predicted higher hospital and higher ED trajectory utilization groups. A major finding in this study was the association of several mental health conditions, including depression, with health care utilization group membership. This finding underscores the importance of routine screening and adequate management of mental health care conditions in AYAs with SCD, especially during transfer to adult care. One goal of this dissertation was to describe successful transition. The majority of our sample has transferred to adult care. The mean age at transfer was 19 years. We also examined the continuity of care after transfer and the majority of participants who transferred to adult care had at least one additional encounter in the adult sickle cell clinic, and around 65% had more than ten encounters. Only a few (5.83%) had no adult encounters after transfer. As a result, we considered the vast majority of participants who had at least one encounter in the adult sickle cell clinic to have successfully transferred and integrated into adult care.</p
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
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.
