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
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
Dietary Fat Intake and Contributing Food Sources of New Zealand Adolescents: Summarising a Decade
No full textBackground: Dietary fat is an essential macronutrient to support rapid growth and development during adolescence, in addition to maintaining numerous metabolic and physiological roles. However, adolescents are vulnerable to the development of poor dietary habits, typified by higher than recommended intakes of total and saturated fat, which may put them at increased risk of developing chronic diseases later in life. Up to date figures are unavailable due to it being a decade since any national nutrition data was collected among this population.
Objective: To investigate dietary fat intake and contributing food sources of fat among male and female adolescents 15-18 years in New Zealand, comparing intakes between the sexes and against current recommendations to highlight any changes over the past decade and identify areas of concern.
Design: The SuNDiAL (Survey of Nutrition Dietary Assessment and Lifestyle) study is a cross- sectional, multi-centre survey of 266 adolescent females and 135 males 15-18 years of age in New Zealand. Female participants in the study were enrolled between February and September 2019 while males were enrolled between February and April 2020. Self-administered questionnaires were used for the collection of demographic information as well as health and vegetarian status. Two non-consecutive 24-hour recalls were used to assess dietary intake and the Multiple Source Method (MSM) was used to adjust for usual intake. Dietary intake data was collated and analysed using the FoodWorks nutrient database. Anthropometric measures (weight and height) were taken during on-site visits to participating schools.
Results: Estimated mean intakes of total fat as a percentage of total energy in this study exceeded recommendations for both sexes (males: 37.5% (36.5-38.4); females: 36.5% (35.8-37.2)). Saturated Fatty Acid (SFA) intakes were also higher than recommended, with approximately 90% of the population not meeting the current Acceptable Macronutrient Distribution Range (AMDR). Although improvement for polyunsaturated fat (PUFA) intakes were seen when compared to the Adult Nutrition Survey 2008/09 (ANS 08/09), intakes remain low (males: 5.6% (5.2-6.0); females: 5.5% (5.3-5.7). The major food groups of saturated fat for males included poultry, milk and cheese while for females they were cheese, bread-based dishes and biscuits. Primary food sources of polyunsaturated fat were poultry, nuts/seeds and grains/pasta for males, and nuts/seeds, bread and potatoes/kumara/taro for females.
Conclusion: While some positive differences were observed in fat intakes among New Zealand adolescents since the last national survey, overall levels are suboptimal and could be improved by reducing saturated fat and increasing polyunsaturated fat intake. Further research is required to evaluate fat intakes within a nationally representative sample and determine if trends seen in this study are characteristic of intakes across the whole population
