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
CHILDHOOD LINEAR GROWTH VELOCITY IN THE PLAINS (TARAI) OF NEPAL : PATTERNS AND RISK FACTORS
Get PDFBackground: High rates of undernutrition endure in Nepal. Measuring linear growth faltering using attained growth measures defined as height-for-age fails to reveal the biologically critical process of faltering that leads to stunting for which measures of growth velocity are better suited and for which no reference exists at annual increments throughout the preschool age range.
Objective: To characterize and compare attained growth (height and weight) of children from the plains (Tarai) of Nepal to that of their global counterparts. To derive a novel annualized linear velocity reference curve for preschool aged chilren using extant reference curves, against which to estimate patterns of linear growth faltering. Finally, to assess antecedent risk factors for growth faltering in age-stratified analyses.
Methods: Children 0-71 months of age residing in 21 wards within 7 Village Development Committees that were systematically randomly selected from the Tarai, were included in the study. Households were visited annually between 2013- 2016 when child anthropmetry was measured and interviews conducted. To evaluate attained growth, linear mixed models with cubic restricted spline terms were used and estimates were contrasted against the WHO Growth Standards. Linear restricted cubic spline models were computed to produce the age- and sex- reference curves. Growth faltering was defined using computed linear growth velocity z-scores (LGVZ) and a cutoff of LGVZ<-2 over a 1 year period. To assess risk factors, cluster-adjusted multivariate logistic models evaluated the odds of growth faltering for risk factors assessed at each annualized growth interval for the interval intiating ages <6, 6-11, 12-23, 24-35, 36-47 and 48-59 months.
Results: Attained growth of Nepali children when compared to the WHO standard curve was close but below the median in early infancy and continued to fall until 24 months of age for height-for-age (HAZ) and ~ 12 months of age for z-scores for both weight-for-height and weight-for-age. Z-score distributions by sex were remarkably similar. Consistency in the prevalence of stunting in children under-five years of age was evident between 2013- 2016 (~35%) while the prevalence of wasting minimally decreased each year to 18% in 2016. The modeled LGV reference curves reflected expected patterns of growth, with a monotonic decreasing trend as children aged. Expressed as LGVZ-scores, departure from the reference median was marked for both sexes, with the percentage faltering being 31.1%, 28.6%, 29.3%, 6.7%, 6.2%, and 6.2% among children WHO standard median, a WHZ< WHO standard median and maternal short stature were revealed as consistent risk factors, regardless of age, associated with an increased odds of faltering across almost all age groups. The only community level factor that revealed a consistent inverse relationship with the odds of faltering was the presence of paved roads in the child’s community.
Conclusions: Use of a novel linear velocity reference and proposed definition of growth faltering (LGVZ < -2) offer a way for programs to identify poor growth of young children irrespective of their attained HAZ. Recalcitrant undernutrition prevails in the Tarai, noted to be the breadbasket of Nepal, with unacceptably high wasting prevalence of ~20% and ~30% linear growth faltering during first 2 years of life. Findings suggest that girls are at a higher risk of early life faltering, and that linear growth faltering is closely associated with low weight-for-height. Intergenerational links are revealed with short maternal stature featuring as a prominent risk factor. Regular growth monitoring allowing for velocity computation coupled with identifying risk factors prior to a year of low growth velocity presents opportunities for identification of children at risk of linear growth faltering prior to its occurrence
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.
