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
THE MEDIATING EFFECT OF INCOME AND EDUCATION USING THE UK NATIONAL AND DIETARY SURVEY (NDNS) DATA
Full text linkDiet substantially contributes to socioeconomic inequalities in cardiovascular morbidity and mortality. High adherence to the dietary approach to stop hypertension (DASH) has been proved effective in lowering blood pressure in patients with cardiovascular disease (CVD) as well as to prevent CVD risk factors in the general population. Little is known about time trends in diet quality and associated inequalities in the United Kingdom (UK). In addition, the causal pathway between education and dietary choices has not been fully explained and the role of income in preventing a healthy diet has not been clarified. This doctorate firstly, aimed to quantify the differences in adherence to the DASH in relation to socioeconomic position (SEP) in the UK and to evaluate recent trends. Secondly, it aimed to quantify the mediating effect of income on the relationship between education and the DASH score in the UK population.
Data used for analysis was obtained from three waves of the National Diet and Nutrition Survey Rolling Programme (NDNS) 2008-2012, 2013-2014 and 2015-2016). The DASH score was calculated based on Fung et al methodology and was calculated using sex-specific quintiles of DASH items. For the first part of the analysis (Paper 2) data analysis included 6435 subjects aged 18 and older who participated in the NDNS. Multiple linear regressions were used to evaluate the relationship between the socioeconomic variables and the DASH score. Quantile regression analysis was used to model the median intake of each component as a function of the socioeconomic variable and the survey year. In the second analysis (Paper 3), analysis was done on
4864 subjects aged 18 and older. Counterfactual-based mediation analysis was carried out to decompose the total effect of education on DASH score into average direct effect (ADE) and average causal mediation effect (ACME) mediated by income.
A gradient relationship between the DASH score and all socioeconomic variables emerged with increasing values of the score at higher socioeconomic positions (SEP effect p value: <0.0001 for education, occupation, and income) in the initial analysis. The interaction term between survey year and the socioeconomic variables was not significant showing that the trend was not different across socioeconomic groups (p >0.05). The estimated difference between people with no qualification and those having the highest level of education was -3.59 points (95% CI: -3.91; -3.20). The difference between people engaged in routine occupations and those engaged in high managerial and professional occupations was -3.40 points (95% CI: -3.87; -2.92), and the difference between subjects in the first fifth and last fifth of the household income distribution was -2.73 points (95% CI: -3.16; -2.29). The widest socioeconomic differences emerged for consumption of fruit, vegetables, whole grains, nuts, seeds and legumes. Mediation analysis indicated that the overall mediating effect of income on the relationship between education and the DASH score was only partial, with an estimated proportion mediated ranging between 6 to 9%. The mediating effect was higher among women (11.6%) and younger people (17.9%).
Findings from this doctorate add an important contribution to the existing literature and more importantly, provide an updated picture of socio-economic inequalities in diet amongst UK adults in context of the whole diet. The results show that overall, the DASH score increased over time, yet the overall score remains low. Moreover,
persistent disparities between individuals with higher versus lower SEP were observed. Additional analysis indicates that low income plays a modest role in explaining educational differences in the UK population. Further research is needed to investigate which other factors may explain differences in diet quality.
In conclusion, findings in this doctorate have substantial implications for public nutrition policy. An immediate implication is the need for public nutrition policies that are individualised to SEP. Targeted interventions for those within the lower SEP need a multi-factorial approach not just focusing on the cost of food but on other factors such as nutrition literacy, attitudes towards healthy eating as well as access to healthy food. Further research is needed to fully investigate which other factors may explain the socioeconomic inequality in the adoption of the DASH diet in UK.

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

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.
