Globally, chronic kidney disease is on the rise!
No full textThe significant global impact of chronic kidney disease (CKD) should be highlighted. This disease affects over 10-13% of the population worldwide, surpassing 800 million individuals. CKD is more prevalent in older individuals, women, racial minorities, and those with diabetes mellitus and hypertension (Kovesdy C. P., 2022)..
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
Mapping the landscape of breast cancer care in Bulgaria: a scoping review
No full textBackground: Breast cancer ranks as one of the most common cancer types in the
world, and in Bulgaria, it represents a quarter of all malignant diagnoses in women.
Breast cancer screening in Bulgaria is the lowest among all European Union (EU)
countries. Existing literature on breast cancer care in Bulgaria is scarce. This study
aims to explore the current trends, patterns, and gaps in breast cancer care in
Bulgaria.
Methods: This study is a scoping review from peer-reviewed databases and grey
literature. The results were screened against the SPIDER methodology's inclusion and
exclusion criteria. Covidence was used in screening and full-text review. The study
included 39 sources.
Results: Breast cancer is the leading cause of cancer mortality in Bulgaria and the
incidence remains lower than the European average due to underreporting. Bulgaria
lacks a structured breast cancer screening programme, leading to low service use,
although essential prophylactic exams are covered by the National Health Insurance
Fund. Barriers like the underuse of treatment and significant delays in reimbursement
of new cancer therapies exist. with lower survival rates compared to the rest of the EU.
While policies focus on increasing screening and improving prevention, practical steps
towards achieving this have not yet been taken.
Conclusion: There is low screening and underreporting of breast cancer rates in
Bulgaria. The lack of full reimbursement of diagnostic methods, limited adoption of the
multidisciplinary approach, and complex market access processes are barriers to
developing efficient treatment plans. Efficient screening and prevention are crucial for
positive outcomes
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
