Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Improving the Iron Status of Children in Kisumu County Kenya Using Porridge Flour Enriched with Bovine Blood
No full textThere is a high prevalence of iron deficiency and anaemia in Kenya with young children and mothers bearing the greatest burden. Bovine blood is acceptable food in Kenya but it largely goes to waste. It therefore could be used to improve local diets as a strategy for preventing anaemia. This study evaluated the effect of consumption of bovine blood enriched porridge, on the iron status of anaemic preschool children in a malaria endemic region of Kenya. A rapid assessment was conducted to determine knowledge, attitudes and practices related to anaemia and bovine blood use in East sub-countyof Kisumu County. This involved four key informant interviews, four focus group discussions, free listing and observations of slaughter houses. This was followed by biochemical screening of 270 children for haemoglobin status. A total of 140 children were tested and out of these a sample of 102 children were selected for the household survey and the intervention. A structured questionnaire was used in the baseline householdsurvey to collect background data on socio-demographic and socio-economic characteristics, food consumption, anthropometric measurements and morbidity characteristics of the children. Iron status was also assessed. Based on the knowledge from the rapid assessment, porridge flour was developed from sorghum, millet and cassava flours and enriched with bovine blood powder. The flours and bovine blood powder were analysed for proximate composition and specific mineral contents. Using the results, Nutri-survey modelling was used to formulate the composite porridge flours to provide approximately 50% of the iron RDA for young children. Sensory evaluation was performed to determine the most acceptable porridge flour. The most acceptable flour was then subjected to shelf life evaluation tests. During the intervention phase of the study, children were randomly allocated to two feeding groups. One group was fed with the porridge containing the blood (intervention group) and the other with the porridge without blood (placebo group). The feeding period lasted six weeks, after which the children were re-evaluated for haemoglobin and iron status. Qualitative and quantitative data were analysed with the help of ATLAS ti, Nutrisurvey and IBM SPSS Statistics Base, version 22 respectively. Summary statistics for age, sex, socio-demographics, anthropometry, and biochemical indicators at baseline were determined to describe the study population. Analysis of covariance was used to determine any differences between treatment groups, and group-specific effect sizes calculated and
P < 0.05 was considered significant. Results of the rapid assessment indicated that the community was aware of anaemia and its main causes. Bovine blood is well-accepted as food and traditional methods exist for it’s preparation for consumption and preservation. The most acceptable porridge mix contained sorghum: finger millet: cassava: blood powder in the ratios of 6:14:10:0.5 respectively, andprovided 54% of the recommended daily intake of iron for 1-3 year old children, when consummed as one cup of porridge daily. The mix had a better shelf life when stored at 35ºC for up to three months.
Out of 270 children screened, 51.86% were anaemic and 34.7% suffered from iron deficiency anaemia. There were no significant differences in the baseline characteristics, morbidity status and nutritional status of children in both feeding groups (p>0.05). The dietary recall indicated that most children (88.9%) were receiving less than the RDA foriron. The prevalence rates of stunting, wasting and underweight were 24.5% and 10.8% and 16.7% respectively. After six weeks of intervention 52.6% of the children achieved normal haemoglobin levels, mostly from the intervention groupwhich had significantly(p= 0.000) higher levels compared to the placebo group.There was also a significant (p< 0.05) difference in soluble transferrin receptor levels between the two groups. However, the mean change in serum ferritin between the groups was not significant (p = 0.080). The study concludes that porridge flour formulated from sorghum, millet, cassava and bovine blood can be effectively used to improve the iron status of anaemic children living in malaria endemicregions of Kenya

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
