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

Long-Term Endocrine Therapy Adherence Following Stress Management for Breast Cancer
No full textDespite life-saving potential, approximately half of women with hormone-receptor positive, early-stage breast cancer fail to complete the recommended 10-year course of Adjuvant Endocrine Therapy (AET). Prior research has elucidated several psychosocial barriers to AET adherence, including depression, anxiety, and poor social support; however, the value of controlling psychosocial distress to improve AET adherence has not yet been established. Of note, psychosocial distress is a primary target of Cognitive-Behavioral Stress Management (CBSM), a group-based intervention for women with newly diagnosed breast cancer. Ten-week CBSM has resulted in increased psychological adaptation to breast cancer. Further, CBSM was associated with less depressive symptoms and improved quality of life in breast cancer survivors at 11-year median follow-up. Given the evidence for the relationship between depression and psychological distress with AET adherence, it is plausible that women in CBSM had improved AET adherence compared to those receiving the control condition. Therefore, the present study examined whether stress management interventions based upon CBSM impacted AET medication adherence behaviors in the long-term. The current study completed 7-year post-baseline follow-up of a cohort of women with newly diagnosed, early-stage breast cancer who received either a 5-week cognitive-behavioral therapy (CBT) intervention (n=55), a 5-week relaxation training (RT) intervention (n=70) (both based on the original CBSM protocol), or a 5-week group-based health education (HE) control (n=58). Women completed a psychosocial battery at T1 (prior to randomization), T2 (after group intervention/2-months post-baseline), T3 (6 months post-baseline), T4 (12 months post-baseline), and T5 (7-years post baseline). Adherence and persistence were measured by self-report using the Endocrine Therapy Medication Usage Questionnaire (ETMUQ), which was created by the research team, and was given at T5 long-term follow-up only. Potential mediators of adherence effects were measured at all 5 timepoints. These included depressive and anxious affect (Affect Balance Scale- depression and anxiety subscales), emotional well-being (Functional Assessment of Cancer Therapy-Breast Emotional Well-Being subscale), cancer-specific distress (Impact of Events Scale- Intrusion scale), social disruption (Sickness Impact Profile- Social Interaction scale), and stress management skills and confidence (Measure of Current Status- Relaxation and Coping Confidence subscales).For intervention effects on persistence, we examined time to self-reported discontinuation by plotting an Unadjusted Kaplan-Meier Curve, and conducted log rank tests to determine group differences. Intervention effects on AET inconsistency were tested using structural equation modeling (SEM), in which the ETMUQ factors that were determined to be reliable and valid via Confirmatory Factor Analysis (CFA) were regressed on the intervention group controlling for covariates. To analyze potential psychosocial mediators of adherence effects, the change in each psychosocial construct over 5 timepoints was tested with Latent Growth Modeling (LGM). A basic change model of the repeated measures variables was constructed to explain the means and covariances of these variables, and a vector of treatment group was then added to the model to determine whether intervention predicted change. Finally, to test for mediation, the LGM was added separately to each factor of the ETMUQ, such that the slope of the variable predicted the adherence factor, and dummy vector of group predicted both the slope of the variable and the factor of the ETMUQ.Of the women prescribed AET who completed long-term follow-up (n=59), less than half (n=28, 47.5%) reported still taking their medication and more than half (n=30; 50.8%) reported having at least some specific problems with adherence while taking the medication. Endorsed reasons for nonadherence were predominately related to routine interruptions and side effects. Intervention condition did not predict persistence (i.e., time to discontinuation) to AET. However, there was an effect of intervention group on long-term adherence as measured by the ETMUQ, such that women receiving RT had significantly better adherence than those receiving CBT on the factor measuring Forgetfulness/Inconsistency, and marginally better adherence on the factor measuring Intentional Nonadherence. Women in the RT condition also demonstrated greater rate of change in the Measurement of Current Status-Relaxation subscale (MOCS-Relax) over the first year of treatment than did those in the CBT condition; however, there were no significant mediation effects of CBT versus RT on either factor of adherence through the slope of the MOCS-Relax.The present study adds to the literature by demonstrating that relaxation training may have some impact on AET self-reported adherence in the long-term above and beyond any effect of CBT. Although the mechanism by which RT may improve adherence was not uncovered in the present analysis, future research should investigate whether relaxation training improves a patients’ self-efficacy to cope with the somatic symptoms related to AET adherence, or whether it may improve patients’ attention and awareness leading to less forgetfulness. In addition, future trials should investigate the ability of a psychosocial intervention that incorporates relaxation training with specific adherence counseling to improve long-term AET adherence and persistence. Overall, these findings illustrate the potential value of psychosocial interventions given shortly after diagnosis to improve AET adherence in the long-term.</p
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.
