Hubungan parameter dosis 3-Dimensional Conformal RadioTherapy dengan kejadian dermatitis radiasi pada pasien kanker payudara setelah pembedahan
Full text linkLatar Belakang Dermatitis radiasi menyebabkan penurunan kualitas hidup pasien kanker payudara dan merupakan efek samping tersering pada pasien kanker payudara yang menjalani radiasi adjuvant. Penggunaan teknik 3-Dimensional Conformal Radiotherapy (3DCRT) memungkinkan dilakukan perhitungan parameter dosis dan sebaran dosis pada kulit dinding dada. Tujuan: Untuk mengetahui hubungan parameter dosis 3DCRT dengan derajat dermatitis radiasi pada pasien kanker payudara setelah pembedahan Metode: Penelitian ini merupakan studi case-control dengan membagi kelompok dermatitis sedang berat sebagai kelompok case dan dermatitis ringan sebagai kelompokm control kemudian dilakukan penelusuran parameter dosis 3DCRT menggunakan “ECLIPS” treatment planning system (TPS). Parameter dosis yang dinilai adalah conformity index (CI), Homogeneity Index (HI) dan dose max sesuai perhitungan menurut standar internasional commission on radiation units and measurements-83 (ICRU-83) Hasil: Uji statistik pada 22 pasien kelompok case dan 22 pasien kontrol menggunakan spearman rho menunjukkan adanya hubungan antara parameter dosis 3DCRT dengan kejadian dermatitis pada pasien kanker payudara setelah pembedahan (p<0,05), OR untuk CI adalah 15,23 (p<0,05), OR untuk HI adalah 6,42 (p<0,05) dan OR untuk dmax adalah 20,25 (p<0,05). Kesimpulan: Parameter dosis 3DCRT berhubungan dengan derajat dermatitis radiasi dan dapat memperkirakan resiko kejadian dermatitis radiasi terutama untuk CI dan Dose max
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
The emerging cancer support system in traditional and religious values: a qualitative study of the cancer community in west Sumatera, Indonesia
No full textComprehensive cancer care was recently developing in west Sumatra province. Accordingly, there was a need to establish a support system for cancer patients while considering traditional and religious values rooted in the community. Objective: To explore the cancer support system and its values in west Sumatra. Methods: In-depth interview with peer group (N=16), Focus group discussion with patients, caregiver, survivor group, Indonesian cancer organization and professional (N = 18) and observations patients interaction in Andalas University Hospital. Results: West Sumatera cancer support consist of several components, which is: health worker for guiding patient during treatment, patient\u27s extended family as decision-maker, financial support, and escort during treatment, friend and colleague for emotional dan spiritual support, survivor groups as emotional support and counter hoax, Indonesian cancer organization to increase awareness dan advocate policy. Each component with different role in order to support cancer patients. Communication and coordination of the support system component were just started and becoming more intense. Traditional and Islamic religious values deeply influence the support system. Conclusion: A cancer support system was emerging in West Sumatera province. The support system involving components around patients, and begin to synergize and accommodate traditional and religious value
