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
Mitochondrial DNA copy number instability in ERBB2-amplified breast cancer tumors
Full text linkIncrease in the copy number of ERBB2, a Tyrosine Kinase Receptor (TKR) leads to the overexpression of oncogene product and consequently uncontrolled cell proliferation which has been reported in different aggressive cancers with mitochondrial malfunctions. Although, amplification of ERBB2 has been reported in different studies; however, the association between changes in mitochondrial DNA content and the ERBB2 gene copy number is poorly understood. The relative mitochondrial DNA content of breast cancer tumor tissues of 70 patients who were referred to Imam Khomeini Hospital Complex was determined using quantitative Real-time PCR. Multiplex ligation-dependent probe amplification (MLPA) was conducted to evaluate the ERBB2 gene copy number variation and finally, two-sample Wilcoxon rank-sum (Mann-Whitney) test was used to investigate the possible association between mitochondrial DNA (mtDNA) content and the ERBB2 gene amplification. Seventeen out of 70 breast cancer tumor tissues were found with ERBB2 gene amplification. Comparison of the mitochondrial DNA content of the aforementioned samples with the rest of the cases showed a significant decrease in the mitochondrial DNA content of the ERBB2-amplified samples (P=0.01). Our data provided evidence that ERBB2 have the potential to have a regulatory role over mitochondrial activity by controlling the mtDNA content
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
قدرت پیشگویی کنندگی سازه های مدل اعتقاد بهداشتی در انجام کمک های اولیه توسط مادران دارای کودک زیر 6 سال در زمان سانحه
Full text linkBackground and Aim: The survey of mother behavior in time of accident and empowerment for management is necessary to achieve health of mothers and children. Therefore for educational need assessment the aim of this study was to determine the Measurement of HBM constructs in the aim first aid to accidents and injuries in mothers with children in Azna city.
Methods: This is a cross sectional and analytical study, that was carried on 100 mothers with children aged less than 6 years are referred to health centers in the city of Azna in 2021-2022. Data was collected with a made research questionnaire reliable and valid based on the Health Belief Model. The data collected were analyzed by software spss16.
Results: The mean and standard deviation of mothers' age was 27.41 ± 3.56 years, children's age was 2.9 ± 1.38 years. The mean scores of mothers' knowledge were 25.8, perceived barrier 61.84, self - efficacy 64.08, the performance was 21.74. The results showed that there was a positive correlation between knowledge, perceived benefits, and a negative correlation between self - efficacy and perceived barrier. In the regression analysis, the age of the child and the construct of perceived barrier and self-efficacy predicted a total of 18% (R2 = 0.180) of behavior changes.
Conclusion: Considering the effectiveness of the constructs of perceived benefits and self - efficacy and perceived barrier, training programs should be focused an implemented to empower mothers to manage the scene when an accident occurs.

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
