Mortality landscape in the Global Burden of Diseases, Injuries and Risk Factors Study
No full textThe Global Burden of Diseases, Injuries and Risk Factors Study 2010 (GBD 2010) is an initiative that involved 486 scientists from 302 institutions in 50 countries, under the leadership of a consortium formed by the Institute for Health Metrics and Evaluation of the University of Washington, World Health Organization, the University of Queensland School of Population Health, the Harvard School of Public Health, the Johns Hopkins Bloomberg School of Public Health, the University of Tokyo and Imperial College London. The study has provided a state of the art understanding of the burden of 67 risk factors and their clusters, 291 diseases and injuries on global, regional and national levels in period from 1990 to 2010 for 187 countries. GBD 2010 estimates covered both mortality (expressed in number of deaths, years of life lost (YLL) due to premature mortality) and morbidity (mainly expressed as years lived with disability (YLD)), while the incidence and prevalence were not reported for majority of causes so far, although they were accounted and used for YLD calculations. Finally, each disease and risk factor was presented in terms of the disability-adjusted years of life (DALY) that is merely a sum of YLL and YLD. The major published results of GBD 2010 cover global and regional levels for all diseases and risk factors. Reports focused on specific conditions are also available. At country-level detailed estimates are published for UK, China and USA, and data on other countries are accessible only as aggregate partial representation via web-based tools. © 2013 European Federation of Internal Medicine.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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

Pragmatic Case Studies as a Source of Unity in Applied Psychology
No full textTo unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe
Core global metrics of chronic kidney disease (CKD) prevalence in the GBD 2019 Study
No full textChronic kidney disease (CKD) is an important contributor to morbidity and mortality from noncommunicable diseases, and is a highly relevant topic in global health.The Global Burden of Disease, Injuries and Risk Factors (GBD) study presents a comprehensive assessment of the global epidemiology of CKD both as a direct cause of mortality and morbidity and as a risk factor for other diseases. The GBD uses term "impaired kidney function (IKF)" to indicate the CKD as a risk factor for ischaemic heart disease, stroke, peripheral vascular disease, and gout, and underline the difference from the term "CKD" itself that refers to a direct cause of morbidity and mortality due to kidney disease.Scientific-Tools.Org created a series of infographics highlighting different aspects of CKD epidemiology at global, regional and country levels.Suggested infographics citation: Suggested citation: Bikbov B.

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
