    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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 link
    We 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

    Advancing cardiovascular disease prevention in asymptomatic carotid artery disease: integrative approaches through dietary interventions, multidisciplinary programs, and adherence strategies

    No full text
    Background Cardiovascular disease (CVD) is the leading global cause of mortality, responsible for 17.9 million deaths annually, with significant economic burdens. Modifiable risk factors, such as poor diet, physical inactivity, and low adherence to preventive strategies, contribute to its high prevalence. High-risk populations, such as those with asymptomatic carotid artery disease (ACAD), face limited effectiveness in current prevention approaches due to insufficient integration of multidisciplinary care and adherence strategies. Objectives This thesis aimed to advance CVD prevention by: 1. Systematically evaluating the DASH diet’s impact on cardiovascular events and risk factors. 2. Investigating outcomes of a novel multidisciplinary risk management program (IP-CARD) for ACAD patients. 3. Assessing the effectiveness of telephone reminders in improving adherence in cardiovascular clinical trials. Methods Three interconnected studies were conducted: 1. A Cochrane systematic review of randomized controlled trials (RCTs) assessed the DASH diet’s effects on cardiovascular outcomes and risk factors. 2. A single-center RCT evaluated the IP-CARD program’s impact on non-fatal cardiovascular events, carotid stenosis progression, and quality of life in ACAD patients. 3. A Study Within a Trial (SWAT) explored the role of telephone reminders in enhancing adherence during a cardiovascular prevention trial. Results 1. DASH Diet Review: The systematic review included five RCTs and demonstrated significant reductions in blood pressure and cholesterol profiles. However, evidence on its effects on myocardial infarction, stroke, or mortality was inconclusive due to limited sample sizes and follow-up durations. 2. IP-CARD Program: The RCT showed a significant reduction in non-fatal cardiovascular events and carotid stenosis progression. Intervention participants achieved better control of blood pressure, LDL cholesterol, and physical activity, alongside significant quality-of-life improvements. 3. SWAT on Adherence: Telephone reminders significantly improved adherence rates and engagement with trial protocols, with potential reductions in dropout rates and improved adherence scores. Conclusions This thesis highlights the potential of integrative approaches combining dietary interventions, multidisciplinary programs, and adherence strategies to reduce CVD risk in high-risk populations. While the DASH diet effectively reduces cardiovascular risk factors, further large-scale, long-term trials are needed to confirm its impact on major events like myocardial infarction and stroke. The IP-CARD program demonstrates the value of structured multidisciplinary interventions in managing ACAD, while adherence strategies, such as telephone reminders, optimize trial engagement and outcomes. Implications This research offers actionable insights for clinical practice, public health policy, and future research. It supports the integration of evidence-based dietary, lifestyle, and adherence interventions into clinical guidelines. Structured prevention programs for ACAD patients and high-risk populations, combined with robust adherence strategies, can significantly reduce the global burden of CVD while improving patient quality of life. These findings emphasize the need for funding and policy support to implement and sustain these programs on a broader scale

    The effect of lifestyle and risk factor modification on occlusive peripheral arterial disease outcomes

    No full text
    This thesis seeks to address the effect of lifestyle and risk factor modification on occlusive peripheral arterial disease outcomes by comparing standard healthcare to structured programme. This thesis is divided into five chapters. The first chapter gives a brief overview of peripheral arterial disease. The second chapter is a Cochrane systematic review (Protocol and the systematic review). This review analysed the effect of mhealth technology to improve walking distance in people with intermittent claudication. The third chapter is a pilot randomised controlled trial (Protocol and RCT). This trial investigated the effect of lifestyle and risk factor modification on peripheral arterial disease outcomes. The fourth chapter is an Observational Study within A Trial (Protocol and study). The Study within A Trial examined the effects of same-day consent vs delayed consent on the recruitment and retention of trial participants. The final and fifth chapter is the discussion of the findings in general, the conclusion and future recommendations2024-09-2

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We 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
