A case report on a rare manifestation of hypothyroid patient; cardiac tamponade
Full text linkHere presented is a patient admitted to our hospital with cardiac tamponade, a rare manifestation of hypothyroidism. Her presentation was non-specific symptoms like easy fatigability, poor appetite and left anterior chest discomfort of 01 year duration. She was evaluated in our hospital before 05 months and was started on anti-tuberculous management. But despite the anti-tuberculous treatment her condition worsened and upon her current admission she has 01 episode of syncope. She was hypotensive and depressed. Pericardial fluid analysis showed a cell count of 200 cells per microliter but mycobacterium tuberculosis was not detected on AFB stain. Cytology of the pericardial fluid revealed just reactive effusion. Tamponade results from increased intrapericardial pressure caused by the accumulation of pericardial fluid. The rapidity of fluid accumulation is a greater factor in the development of tamponade than absolute volume of the effusion. Hypothyroidism is a well-known cause of pericardial effusion. However, tamponade rarely develops owing to a slow rate of accumulation of pericardial fluid. The treatment of hypothyroidic cardiac tamponade is different from other conditions. Thyroxine supplementation is all that is necessary. Rarely, pericardiocentesis is needed in a severely symptomatic patient. Our patient improved with levothyroxine treatment
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
Pregnant mothers’ knowledge, attitude and practice towards preventions of iron deficiency anemia in Harar town, Ethiopia
Get PDFLow maternal risk perception, poor dietary practice and low adherence to iron and folate tablets among pregnant women are major contributors for higher burden of anemia. Iron deficiency anemia contribute to more than half of Anemia among pregnant women. Thus the level of maternal awareness and attitude towards dietary and other prevention practices of anemia are not well established in the study area. This study was to assess knowledge, attitude and practice of pregnant mothers towards the prevention of iron deficiency anemia in Ethiopia, 2018. Hospital based cross sectionals study was conducted on randomly selected, 128 pregnant mothers attending antenatal care service in Harar town. Data were collected by health professionals using pre tested questionnaire containing socio demographic, knowledge, attitude and practice related questions. Attitude questions were organized in five Likert scale from strongly disagree to strongly agree using positive statements. Similarly, practices were assessed in yes/no (appropriate practices were scored as yes or no otherwise). Data was analyzed using SPSS version 20 using frequency, tables, graphs and means. Pearson correlation with r was used to assess the relationship between knowledge, attitude and practice. Analysis of Variance was used to compare the mean practice by different factors. Knowledge, attitude and practice of pregnant women on preventions of IDA are not satisfactory. Thus poor practice towards prevention of IDA is the main contributing factor for high burden of anemia.
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
