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
Comparison of infant feeding practices, nutrient intake and body weights by childcare use
Get PDFThe child care setting represents a crucial environment for infants and children to establish healthy feeding practices in order to prevent overweight and obesity. The objective of this research was to investigate the association between parental care (PC) and child care (CC) on infant feeding practices, food consumption, nutrient intake and growth in infants receiving Special Supplemental Nutrition Program for Women Infants and Children (WIC) assistance. Our hypothesis was that unhealthy feeding practices would be more common in CC compared to PC thus leading to greater weight for length (WFL) and weight for age (WFA) z-score at 1 year of age for infants in CC. This study sampled 105 infants aged 2 to 8 months of age from the Champaign Urbana WIC office from October 2009-August 2011. Mothers completed a 3-day food record and survey at the time of recruitment to assess their infant’s feeding practices, nutrient intake, health status, and demographic characteristics. Baseline and follow-up weight and length for these children within the first year of age were collected from the WIC office.
The major differences in demographic characteristics of the study sample included child care hours per week, maternal employment, household income, and single parent home by CC use. Infants in CC had an average of 29 hours of care per week compared to the 0.64 hours in the PC group (p<0.01). A larger (p<0.01) percentage of mothers were employed in the CC group (73.9%) compared to the PC group (22%). However, the household income was greater (p<0.01) in the PC group (10,284 PC vs 7,489.5 CC). In addition, there was a higher (p=0.04) percentage of single parents in the CC group (30.5 % PC vs. 50% CC).
Breastfeeding duration and age of solid food introduction did not differ between care type. Breastfeeding duration was on average 2.3 months while average solid food introduction was 4.4 months. No differences were observed between PC and CC infants in the rates of formula introduction. When comparing food consumption at the time of recruitment, there were no differences in the number of servings per day of food groups, but the CC group showed lower consumption of formula (p=0.03) and breast milk (p=0.18) compared to PC.
Energy intake did not differ between care type after adjusting for feeding practices and child, maternal and household characteristics. However, there was a pattern of greater energy intake in the PC group. Child age (β=34.8, p<0.01) and number of servings of infant formula (β=86.0, p<0.01) were the strongest predictors of energy intake. There was greater (p=0.05) calcium intake in the CC group (788 mg CC vs. 742 mg PC). Otherwise, there were no differences in macro or micronutrient intakes between CC and PC.
For growth measures, infants in PC had a significantly greater change in WFL (β=2.06, p=0.05) and WFA (β=1.69, p=0.01) z-score and a greater follow-up z-score, after adjusting for feeding practices and child, maternal and household characteristics. There were no differences by care type in the length for age (LFA) z-score over the first year of life.
The strongest predictors of the change in WFL z-score were PC use (β=2.06, p=0.05), maternal pre-pregnancy BMI (β=0.14, p<0.01), birth order (β=1.63, p<0.05), maternal age (β=-0.34, p<0.01), birth weight (β=-1.77, p=0.06), non-Black/African American (β=3.09, p=0.02) and male gender (β=-2.12, p=0.06). Change in WFA z-score was significantly affected by CC use (β=1.69, p=0.01), lower birth weight (β=-1.74, p<0.01), greater pre-pregnancy BMI (β=0.09, p<0.01), and less servings of infant formula (β=-0.53, p=0.05). Change in LFA was unaffected by CC use (β=1.69, p=0.11), but significantly affected by lower pre-pregnancy BMI (β=-0.04, p=0.04) and black race (β=-2.54, p=0.05).
Thus, we concluded that CC use did not affect feeding practices, overall nutrient intake or LFA z-scores for infants receiving WIC assistance. There was significantly greater calcium intake in the CC group. CC use also showed a trend of less formula and breast milk. Infants in PC had a statistically greater change in WFL and WFA compared to those in CC. The main finding in this study is that CC use may have influenced differences in the change in WFL and WFA z-scores, but not overall infant feeding practices, nutrient intake and LFA z-score. Future longitudinal studies are warranted to explore the role of CC use on feeding practices, nutrient intake and growth.Item withdrawn by Mark Zulauf ([email protected]) on 2012-07-11T13:31:10Z

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

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.
