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

Bidirectional Relationships between Cardiovascular Disease and Lung Cancer, and Racial Disparities of Cardiovascular Disease and Depression in Lung Cancer Patients
No full textBackground: Lung cancer is the second most common cancer among men and women in the US, with an estimated 226,650 new cases (11% of all cancer types) expected to be diagnosed in 2025. It also accounts for the highest proportion of cancer-related deaths, with an estimated 124,730 deaths (20% of all cancer types) in 2025. Lung cancer patients have relatively poor survival outcomes compared to those diagnosed with most of other cancer types, though the number of people living with lung cancer is expected to increase over the coming decades.Cardiovascular disease (CVD) has been the leading cause of death in the US, responsible for 941,652 deaths in 2022. From 2017 to 2020, approximately 9.9% of US adults (28.6 million) were affected by CVD, including coronary heart disease (CHD), heart failure (HF) and stroke. The total burden of CVD, including direct and indirect costs, was $417.9 billion from 2020 to 2021.
Cardio-oncology, a multidisciplinary field focused on cardiotoxicity related to cancer treatment, has emerged over the past several decades. Lung cancer and CVD share multiple risk factors, including tobacco smoking, age, sex, diet, alcohol consumption, overweight/obesity, diabetes, and environmental and occupational exposures.
Depression is also a prevalent condition. According to 2023 reports, an estimated 17 million adults in the US, were affected by depression, with approximately 7% of Americans experiencing a 12-months persistent prevalence of major depressive disorder. Lung cancer patients may face severe mental and physical stress due to a poor prognosis, relatively low survival rate, and side effects of treatments.
Previous studies have reported that Asian, Native Hawaiian, and Pacific Islander (ANHPI) lung cancer patients have poor experiences related to diagnosis and treatments. Lung cancer risk and healthcare outcomes after diagnosis may vary across ANHPI subgroups, due to diversity and heterogeneity in acculturation, disease-related stigma, and socioeconomic status.
Objective and Specific Aims: The aim of this study is to investigate bidirectional associations between CVD and lung cancer, as well as racial and ethnic disparities in cardiovascular disease and depression among lung cancer patients. The specific aims are: (1) to investigate the associations between the prevalence of CVD conditions (heart failure, ischemic heart disease and stroke) and lung cancer incidence in an older population; (2) To investigate the risk of CVD (heart failure, ischemic heart disease and stroke) among older lung cancer patients who are ANHPI or non-Hispanic White (NHW); (3) To investigate the risk of depression among older lung cancer patients among ANHPI and NHW populations.
Methods: We utilized the SEER-Medicare dataset to identify first primary lung cancer cases. The CVD conditions of interest were ischemic heart disease, heart failure and stroke/transient ischemic attack.
For Aim 1, we conducted a nested case-control study among lung cancer cases aged 70 years or older at diagnosis between 2004 and 2019, and non-cancer controls selected from Medicare beneficiaries. Each case was matched to a control based on age, sex, state, and index year. We used conditional logistic regression to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for differences in CVD prevalence at least 5 years prior to the index year between cases and controls. We also performed logistic regression for CVD at least 10 years prior to the index year.
For Aim 2 and 3, we conducted matched cohort studies, including ANHPI and NHW lung cancer patients who were 66 years and older and diagnosed between 2000 and 2017. Each ANHPI patient was matched to three NHW patients on age of diagnosis (+/-1 year), calendar year of diagnosis (+/-1 year) and sex. We used Cox proportional hazards models to estimate hazard ratios (HRs) and 95% CIs for CVD and depression risk comparing ANHPI to NHW patients, and among ANHPI subgroups.
Results: In Aim 1, lung cancer risk was higher among individuals with ischemic heart disease more than 5 years prior to the index date (OR=1.22, 95% CI=1.13-1.33), compared to individuals without ischemic heart disease. Analyses were adjusted for demographic covariates, socioeconomic status (SES), baseline Charlson Comorbidity index (CCI), tobacco use, alcohol consumption and obesity. Stratified analyses showed elevated lung cancer risk associated with ischemic heart disease more than 5 years prior to diagnosis among females (OR=1.37, 95% CI=1.23-1.53), NHW individuals (OR=1.17, 95% CI=1.09-1.26) and individuals of other races (OR=1.49, 95% CI=1.14-1.96).
In Aim 2, compared to NHW lung cancer patients, ANHPI lung cancer patients had a lower incidence of heart failure (HR=0.64, 95% CI=0.53, 0.76) and ischemic heart disease (HR=0.76, 95% CI=0.60, 0.95). Specifically, Chinese, Japanese and other Asian lung cancer patients had lower incidences of both conditions compared to NHW patients. However, when compared to Chinese lung cancer patients, several ANHPI subgroups, including Filipino, Indian/Pakistani, other Southeast Asian and Pacific Islander lung cancer patients had higher risks of heart failure. Indian or Pakistani lung cancer patients also had a higher risk of ischemic heart disease compared to Chinese patients (HR=1.76, 95% CI=1.05, 2,96).
In Aim 3, when compared to NHW lung cancer patients, overall ANHPI lung cancer patients had a lower incidence of depression (HR=0.60, 95% CI=0.50-0.73). Specifically, Chinese, Japanese, Filipino, Asian Indian or Pakistani lung cancer patients experienced lower incidence of depression than NHW patients. However, Korean lung cancer patients had a higher incidence of depression compared to Chinese patients (HR=1.62, 95% CI=1.05-2.51).
Conclusions: We observed an increased risk of lung cancer among individuals with pre- existing ischemic heart disease. Although overall ANHPI lung cancer patients experienced lower risks of cardiovascular disease and depression compared to NHW patients, certain subgroups, such as Indian or Pakistani patients (higher CVD risk) and Korean patients (higher depression risk) faced elevated health burdens relative to Chinese patients. These findings suggest the possible benefit of targeted lung cancer screening among patients with ischemic heart disease and underscore the needs for tailored healthcare strategies for specific ANHPI subgroups. Further research is warranted to understand the underlying mechanism behind these associations, and studies with larger, disaggregated samples of ANHPI populations are needed to inform equitable cancer and CVD prevention and clinical care
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.
