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
Bilateral neglected posterior dislocation of the shoulder treated by reverse arthroplasty and contralateral osteochondral autograft. A case report
Full text linkBilateral posterior dislocation of the glenohumeral joint is an uncommon event, that can be missed at the initial presentation. We report the case of a 76-year old woman, who suffered a traumatic bilateral posterior dislocation, that was diagnosed three months later. She underwent surgical treatment on both shoulders in a single stage. Since the right shoulder showed a defect of the articular surface >50%, a reverse shoulder arthroplasty was performed on this side. The resected portion of the humeral head was retrieved and used as osteochondral graft to fill the reverse Hill-Sachs lesion of the left shoulder. At 18-month follow up, the patient was pain-free and had recovered excellent shoulder function on both sides: Constant score was 79 for the right shoulder and 88 for the left one. X-rays showed a grade 1 scapular notch of the right reverse prosthesis and good incorporation of the graft in the left shoulder, with no evidence of degenerative joint changes. Neglected posterior dislocations of the shoulder can be surgically treated by replacement or reconstruction. In case of bilateral injuries, the surgeon should carefully evaluate the pathoanatomy of both glenohumeral joints in order to choose and plan the most suitable procedure. If shoulder replacement is required on one side, the resected portion of the humeral head can be used as osteochondral autograft for a reconstruction procedure in the opposite side. The choice is influenced by several variables and decision-making might be challenging
A framework assessing the footprints of food consumption. An application on water footprint in Europe
Full text linkInnovative sustainable food systems should be defined to meet the future food demand (both in terms of quality and quantity) and to overcome the threats that current food systems are posing to the natural capital. To achieve this ambitious goal, the transition to sustainable food habits should be supported by methodological frameworks and modelling tools promoting human and environmental health. The proposed framework provided a standardized system-based approach for the analysis of environmental impacts of food systems, assessed in terms of use of natural resources (water and ecological footprint) and GHG emissions (carbon footprint). The framework is applied to the assessment of water footprint of cradle-to-gate European food consumption, resulting in an average water footprint consumption of 3291 (±557) litre (per day per person). The case study showed the potentiality of our framework as a support tool for policy making in designing specific incentives for the reduction of environmental impacts related to the agri-food sector, as well as in the evaluation of agronomic strategies in the light of pursuing the environmental sustainability of food commodities production. The main novelty presented in the case study is to use food consumption data coming from surveys harmonized across European countries to assess the real food demand
Digital native students using nutritional apps: are they more adherent to a mediterranean diet model? Results from the good APPetite survey
Full text linkReading and understanding food labels are crucial steps in healthy dietary choices. Nutritionrelated applications (n-apps) have increased in the recent years and the aim of this study was
to assess the use and the perception of n-apps among a population of university students, also
investigating the attitude and relationship with reading food labels and adherence to the Mediterranean diet (Medi-Lite score).
In 2023, 316 students, mainly attending the courses of Medicine, Pharmacy and Dietetics at the
University of Brescia, Italy, completed an anonymous and specifically designed survey. 33.9% of
the students stated that they use or have used n-apps. The most used apps were Yuka, MyFitnessPal, Fat Secret and Yazio, especially for the ease of use, speed, nutritional values estimation
and barcode reading. 53.2% and 53.5% of the students declared to be food information and
nutrition label readers respectively and the Medi-Lite mean value was 9.98 ± 2.46. N-app-users
were significantly more attentive to food information and nutrition label than app not-users (both
p < 0.0001) and recorded a Medi-Lite score significantly higher (p = 0.0131).
The present study found for the first time an extensive correlation between the use of n-apps,
the food labels awareness and healthy eating habits in a digitally native population
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
