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
Tradition of use on medicinal species in Valfurva (Sondrio, Italy)
No full textETHNOPHARMACOLOGICAL RELEVANCE:
In the past Alpine populations were isolated from comforts of industrial and technological development present in large cities and, therefore, they were obliged to find in nature a source of sustenance and care. Traditional use of plant is a wealth of local knowledge that is likely to be lost. This work, carried out during 2012, aims to collect, analyze and process information on the species used for medicinal, veterinary, cosmetic, domestic, ritual and religious purposes by the inhabitants of Valfurva, in the Province of Sondrio (Italy). Furthermore it is a means for the preservation of local traditions regarding such uses and increases the ethnobotanical data from Northern Italy, till now poorly documented.
METHODS:
Our survey was conducted by semi-structered interviews. We interviewed 92 people, aged from 23 to 97 y.o., born or resident in Valfurva. All information collected and concerning their use of plants, were analyzed using ethnobotanical indices such as Relative Frequency of Citation (RFC), Relative Importance (RI) and Factor Informant Consensus (FIC).
RESULTS:
Our study stated that people living in Valfurva use 126 species belonging to 48 families. Findings revealed that the most cited species is Achillea moschata Wulfen, with values of RFC and RI equal to 1.00 and 1.12 respectively. Furthermore, 95 species were collected in the wild and 31 were cultivated. The most commonly used part plants were leaves, flowers, fruits, roots and complete aerial parts. The most frequent preparation methods were infusion, decoction and poultice. Among the recorded species, 91 of them are used for medicinal purposes, 72 for cooking, 19 for veterinary purposes, 10 for animal feed, 12 for cosmetic practices, 7 for religious or ritual purposes and 45 for domestic and various uses. The validity of the species use emerged in our survey is confirmed by scientific literature and research conducted on the same topics.
CONCLUSIONS:
This study increases ethnobotanical data coming from Italian Alps, whose regions have been so far hardly investigated. Our study confirms the interest in species already mentioned in previous surveys and placings. It also provides evidences which could be usefully exploited by new investigations aimed at knowing the active metabolites found responsible for plants use in traditional medicine
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
Bytes vs Bio: Prospects and Concerns in AI, Art and Cultures' Confluence
No full textThe paper provides an overview of the main current intersections between Artificial Intelligence (AI) and the realms of art and culture. It evaluates whether AI technologies can bring about changes in aesthetic preferences and the creative production process while preserving human originality. The exploration covers AI's implications in art and culture, drawing inspiration from
Manovich's insights on supervised and unsupervised machine learning's impact on traditional and unexplored aesthetics. The paper delves into AI's influence on individual artists and their creations, its role in cinematic storytelling, trailer creation, immersive cinema, and support from companies like Google and Microsoft. Additionally, it examines AI's contribution to cultural archives, museums, and institutions, recognizing the complexity of evaluating AI-generated art and emphasizing the need for time to assess its cultural impact, positioning AI as a potential stimulant for imagination and emotion alongside human creativity
Creativity in art and in problem solving tasks: a comparative analysis
No full textAs stated in our previous preliminary work [1], creativity can be considered a complex cognitive process, allowing our mind to find original solutions, new perspectives, further ways to organize the incoming data so as to give rise to an enriched reality [2]. In Cognitive Sciences, creativity is often studied as a part of a complex problem solving process. In this work we propose a comparison of the two processes, analysing, through brain data, collected by a BCI (Brain Computer Interface) device, the effect on two selected individuals involved, respectively, in a creative process and in a problem solving task
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
