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
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
Cancer, diabetes and vascular complications : an epidemiological cohort approach
No full textL’augmentation de l’incidence des cancers et la mortalité qui en résulte sont un enjeu de santé publique, accentuées par le vieillissement de la population. Parmi les comorbidités liées au vieillissement, nous avons souhaité préciser le poids du diabète, en particulier de type 2 (DT2) en raison, comme le cancer, de sa forte prévalence en population âgée et de ses conséquences multi-systémiques. Ce travail explore la relation entre le diabète, ses complications vasculaires (CV) et le cancer, avec un intérêt particulier pour la situation gériatrique. Cette thèse s’appuie sur plusieurs publications finalisées et en cours :Article 1 : Comprehensive geriatric assessment in older patients with cancer: an external validation of the multidimensional prognostic index in a French prospective cohort study. BMC Geriatr. 2020;20:295. doi: 10.1186/s12877-020-01692-8L’hétérogénéité de l’état de santé des personnes âgées appelle à l’identification des facteurs de fragilité influençant l’espérance de vie lors du diagnostic oncologique et du suivi. L’évaluation onco-gériatrique permet d’identifier la fragilité du patient âgé cancéreux. Cette étude onco-gériatrique portait sur 433 patients inclus pendant deux ans (femmes 42% ; âge moyen 83±5 ans). Elle a mis en exergue une association entre le score de comorbidités (exploré par le Cumulative Illness Rating Scale for Geriatrics dans le cadre de l’index gériatrique multidimensionnel MPI Multidimensional Prognostic Index) et la mortalité à 12 mois. Par rapport au groupe 1, les sujets des groupes MPI 2 et 3 avaient un risque de mortalité plus élevé (HR ajusté 1,56 [IC à 95% 1,70–2,09] et 1,72 [1,33–2,22], respectivement).Article 2 : Frailty and diabetes status in older patients with cancer : impact on mortality in the ANCRAGE cohort. Aging Clin Exp Res. 2020. doi: 10.1007/s40520-019-01362-9. Quelle est la relation entre diabète, fragilité onco-gériatrique et mortalité chez des patients âgés atteints de cancer ? Dans la cohorte monocentrique ANCRAGE, nous avons analysé les facteurs associés au pronostic chez 1092 sujets âgés atteints de cancer (47% femmes, âge moyen 82±5 ans) dont 20 % étaient diabétiques. La prévalence de la fragilité est élevée dans cette cohorte onco-gériatrique (84 %). Au cours du suivi (médiane 15 mois [6-29], 60% décès), le risque de mortalité était plus élevé chez les patients diabétiques présentant des complications vasculaires (aHR 1,75 [1,15-2,66]), en comparaison avec les sujets non diabétiques et diabétiques sans complication vasculaire.Article 3 : Diabetes phenotypic characteristics and incident cancer: A cohort approach in French patients with type 2 diabetes - The SURDIAGENE study (manuscrit en cours de préparation)Les complications vasculaires (CV) majorent l’évolution de la maladie cancéreuse et la mortalité. Pourtant la relation entre le décès et les CV du DT2 n’a jamais été explorée dans un contexte oncologique. Nous nous sommes focalisés sur la relation entre CV du DT2 et cancer : incidence, progression, décès. Cette étude de la cohorte locale SURDIAGENE incluait 1468 patients diabétiques (42% femmes, âge moyen 65±11 ans, 8% cancer prévalent, 14% cancer incident au cours du suivi moyen de 7±4 ans). Nos résultats confirmaient le sur-risque de mortalité globale chez les patients diabétiques avec une histoire ancienne ou actuelle de cancer (n=313), d’autant plus marqué en présence de CV (HR 1,73 [1,25-2,38]). Nos analyses n’identifiaient pas d’association entre les CV du DT2 et cancer (prévalent et incident), la progression ganglionnaire et/ou métastatique, et le décès lié au cancer. Il n’existait pas non plus de relation entre le cancer et plusieurs biomarqueurs plasmatiques de voies métaboliques impliquées dans l’apparition des CV : le stress oxydant et l’inflammation systémique. Nos résultats ouvrent des pistes pour une amélioration de la prise en charge oncologique des personnes âgées avec diabète.Increases of cancer incidence and mortality are a major public health issue, accentuated by population aging. Among the age-related comorbidities, we wanted to specify the burden of diabetes, in particular type 2 (T2D) due to, like cancer, its high prevalence in older population and its multi-system consequences. This work explores the relationship between diabetes, its vascular complications (VC) and cancer, with a particular interest in the geriatric setting. This thesis is based on several finalized and ongoing publications:Article 1: Comprehensive geriatric assessment in older patients with cancer: an external validation of the multidimensional prognostic index in a French prospective cohort study. BMC Geriatr. 2020; 20: 295. doi: 10.1186 / s12877-020-01692-8Heterogeneity of health status in older age claims for the identification of frailty factors influencing life expectancy during oncological diagnosis and follow-up. The geriatric oncology assessment identifies frailty of older patient with cancer. We evaluated the impact of co-morbidities on life expectancy. This geriatric oncology study involved 433 patients included for two years (42% women; mean age 83 ± 5 years). It highlighted a significant association between comorbidities score (assessed by the Cumulative Illness Rating Scale for Geriatrics as part of the MPI Multidimensional Prognostic Index) and 12-month mortality. Compared to group 1, MPI groups 2 and 3 individuals have a higher risk of death (adjusted HR 1.56 [95% CI 1.70–2.09] and 1.72 [1.33–2.22], respectively).Article 2: Frailty and diabetes status in older patients with cancer: impact on mortality in the ANCRAGE cohort. Aging Clin Exp Res. 2020. doi: 10.1007 / s40520-019-01362-9.What is the relationship between diabetes, geriatric oncology frailty and mortality in older cancer patients? In the single-center ANCRAGE cohort, we analyzed the prognostic factors in 1092 elderly subjects with cancer (47% women, mean age 82 ± 5 years), with 20% of diabetic. Frailty prevalence was high in this cohort (84%). During follow-up (median: 15 months [6-29], death in 60%), risk of mortality was higher in patients with diabetes vascular complications (aHR 1.75 [1.15-2.66]), compared to non-diabetic counterparts and whose with diabetes but no VC.Article 3: Diabetes phenotypic characteristics and incident cancer: A cohort approach in French patients with type 2 diabetes - The SURDIAGENE study (manuscript in preparation)Vascular complications increase the progression of cancer and mortality. Yet the relationship between death and diabetes VC has never been explored before in an oncological setting. We focused on the relationship between diabetes VC and cancer: incidence, progression, death. This study in the local SURDIAGENE cohort included 1468 diabetes patients (42% women, mean age 65 ± 11 years, 8% prevalent cancer, 14% incident cancer during the mean follow-up of 7 ± 4 years). Our results confirmed the increased risk of overall mortality in diabetes patients with a past or current history of cancer (n = 313), which was all the more marked in presence of VC (HR 1.73 [1.25-2.38]). Our analyses did not reveal any association between diabetes VC and cancer (prevalent and incident), lymph node and / or metastatic progression, and cancer-related death. There was no relationship between cancer and several plasma biomarkers of metabolic pathways involved in the development of CV: oxidative stress and systemic inflammation.Our results pave the way for improving cancer care in older people with diabetes
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.
