Age- and sex-specific analysis of the impact of bipolar disorder in Iran and its provinces: Prevalence, incidence, and disability-adjusted life years: Global burden of disease 2021
Objectives: This study sought to deliver a prevalence, incidence, and Disability-Adjusted Life Years (DALYs) of bipolar disorder in Iran, covering both national and subnational scales. The results were broken down by age group and sex, alongside an analysis of trends in bipolar disorder from 1990 to 2021. The estimates gathered were further compared to global averages to offer deeper insights into the prevalence and impact of bipolar disorder in Iran. Methods: This study analyzed data from the Global Burden of Disease 2021 framework to assess various health metrics. Key indicators such as prevalence, incidence, and Disability-Adjusted Life Years (DALYs) were examined using all-age count estimates and age-standardized rates per 100,000 individuals. The analysis spanned the years 1990 to 2021, with results categorized by sex, age group, and geographic location. Furthermore, percentage changes over this period were calculated. To enhance the reliability of the findings, all reported estimates included a 95 % uncertainty interval. Results: In 1990, the age-standardized prevalence rate of bipolar disorder in Iran was 770.09 per 100,000 individuals [95 % UI: 657 to 902], and by 2021, it slightly increased to 780 per 100,000 [95 % UI: 667 to 915]. The percentage change over the period from 1990 to 2021 was 0.01 %. In 2021, the total number of bipolar disorder cases in Iran was reported at 724,891, with a 95 % uncertainty interval ranging from 614,626 to 848,263. Among these cases, 376,813 were observed in females and 348,077 in males. Notably, individuals aged 10 to 24 accounted for 127,388 of the overall cases, making this age group the most affected. The age-standardized incidence rate (per 100,000) of bipolar disorder was estimated to be 52 [95 % UI: 44 to 61] in 1990 and 53 [95 % UI: 45 to 62] in 2021, reflecting a minimal change of 0.01 % over this period. Similarly, the age-standardized disability-adjusted life years (DALYs) rate (per 100,000) for bipolar disorder was recorded at 164 [95 % UI: 107 to 240] in 1990 and 166 [95 % UI: 109 to 241] in 2021, with an equivalent negligible change of 0.01 % from 1990 to 2021. Discussion: In Iran, the burden of bipolar disorder has been found to exceed global averages, and due to demographic changes, young population, regional stressors this burden has grown significantly over the past three decades. Therefore, it remains crucial to focus increasing access to mental health care by increasing mental health care infrastructure in the country, especially in densely populated areas
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
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
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
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
