Decision-making styles in an evolutionary perspective
No full textNaturalistic decision-making (NDM) investigates the cognitive strategies used by experts in making decisions in real-world contexts. Unlike studies conducted in the laboratory, the NDM paradigm is applied to real human interactions, often characterized by uncertainty, risk, complexity, time pressures and so on. In this approach, the role of experience is crucial in making possible a quick classification of decision-making situations and therefore in making an effective, rapid and prudent choice. Models of behaviour resulting from these studies represent an extraordinary resource for research and for the application of decision-making strategies in high-risk environments. They particularly underline not only that most of the critical decisions that we take are based on our intuition, but that the ability to recognize patterns and other signals that allow us to act effectively is a natural extension of experience. © Springer Nature Singapore Pte Ltd. 2020
Designing a Recommender System for Touristic Activities in a Big Data as a Service Platform.
No full textDesigning e-services for tourist today implies to deal with a large amount of data and metadata that developers should be able to exploit for generating user perceived values. By integrating a Recommender System on a Big Data platform, we constructed the horizontal infrastructure for managing these services in an application-neutral layer. In this chapter, we revise the design choices followed to implement this service layer, highlighting the data processing and architectural patterns we selected. More specifically, we first introduce the relevant notions related to Big Data technologies, we discussed the evolving trends in Tourism, and we introduce fundaments for designing Recommender Systems. This part provides us with a set of requirements to be fulfilled in order to integrate these different components. We then propose an architecture and a set of algorithms to support these requirements. This design process guided the implementation of an innovative e-service platform for tourist operators in Italy
Visual Sociology in the Classroom: Fostering Interaction Awareness Using Video
No full textIn this paper we will present an empirical research about the interactions between teacher and students in a grade three of a secondary school analyzed with video. The methodologies, which shaped our data collection and analysis, are the action research, the conversation analysis of institutional talk within a class, the stimulated recall, and the visual sociology with Computer-Assisted Qualitative Data Analysis Software. We taped some lessons; through the replay of their daily activity we involved students and teacher separately in an auto-observation and video analysis process with the software Transana, highlighting those behaviors which were outstanding for them, eliciting their subjective meanings. Finally we organized a group discussion about the respective interpretative video analysis of the lesson, allowing a reciprocal meta-communication.
This method of group video–analysis forces a re-examination of fixed practices, helping to redefine rigid patterns of interaction and didactic routine
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
