Cultural Heritage communication between narrative and creativity. 3D Video Mapping Projection and new suggestions of Augmented Space
No full textIn the Knowledge Society, Cultural Heritage plays a fundamental role in the development of structured communities. The rise of digital communication in everyday life, has produced a deep effect on identities and cultures, transforming the shape of access and transmission of knowledge. In this effort, the application of digital innovative technologies to Cultural Heritage represents a new frontier of research, preservation, valorisation and communication, as well as new experiences for the cultural tourism sector. Indeed, these technologies extend the possibilities to act on the visitor’s experience, contributing to richer interpretations of the past, bringing new perspectives to questions of identity and culture and generating societal and economic benefits. Video mapping results from the interaction of video content (2D or 3D) projected on any surface, as historic buildings, monuments, archaeological sites. To obtain optimal results, it’s necessary that the projected content is designed specifically for the selected surface. These projections can also be interactive and this feature reveals a huge communication potential, when projections are aimed at promoting the historical and archaeological heritage. The result is a very intense and involving performance, which becomes an attraction and an instrument of participation and information for the tourists
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
Mappa reale o cognitiva? AI generativa a supporto dei ricordi
No full textLo studio si propone di affrontare il tema dell’orientamento spaziale approfondendo in quale modo l’Intelligenza Artificiale possa essere in grado di suggerire nuove metodologie progettuali per generare sistemi di wayfinding inclusivi e con focus sull’utente.
L’intelletto umano è solito generare mappe cognitive dei luoghi che sono stati visitati: in seguito all’esperienza sensoriale vengono infatti immagazzinati e codificati una serie di stimoli che, se associati, costituiscono l’immagine più o meno nitida dello spazio in questione.
Questo processo, come dimostrano le ricerche di May-Britt Moser ed Edvard Moser (2015), è legato all’attività di una complessa rete neurale capace di stoccare rapidamente grandi quantità di informazioni spaziali non correlate. In alcuni casi, però, le mappe cognitive che rievochiamo possono essere contaminate da falsi ricordi, ossia da somiglianze percettive, associazioni semantiche e influenze illusorie, che contribuiscono a produrre immagini distorte della realtà (Diodoro & Meli, 2022).
Qualora la segnaletica di un ambiente non fosse stata progettata a dovere può contribuire dunque a inviare impulsi confusi al sistema nervoso che, durante l’azione di stoccaggio delle informazioni, non sarà in grado di catalogare a dovere; è dunque evidente che un sistema di wayfinding “fisico” può essere capace di influenzare quello “mentale” producendo nell’utente una visione distorta del medesimo ambiente.
In questo contesto l’utilizzo dell’Intelligenza Artificiale potrebbe agevolare e velocizzare la riprogettazione della segnaletica tenendo conto dei requisiti di accessibilità e inclusività per uno studio centrato sull’utente. Si propone tuttavia di non utilizzare la tecnologia per raggiungere l’output finale, bensì, come suggerisce il filosofo Luciano Floridi nel libro “Etica dell’intelligenza artificiale” (2022), di adoperarla come strumento a servizio dell’uomo.
La forma di Intelligenza Artificiale che si intende impiegare è di tipo “generativa”, quella cioè in grado di produrre nuovo materiale, in questo caso immagini. Il lavoro del progettista prevede dunque l'elaborazione di un prompt in grado di riflettere i ricordi che l’utente custodisce riguardo a uno spazio precedentemente navigato, per poi fornirlo all’AI e ottenerne una restituzione grafica. Quest’ultima viene poi messa a confronto con la realtà per andare a evidenziare eventuali errori di percezione che l’essere umano elabora in seguito a stimoli esterni confusi, quali il sistema di orientamento spaziale.
Sebbene vi siano idee controverse sull’ipotesi di collezionare ricordi attraverso l’uso di questa tecnologia (Fui-Hoon Nah et al., 2023), l’applicazione proposta non trova alcuna controindicazione: non solo consente di eliminare nel visitatore l’errore di percezione e fruizione dello spazio, ma garantisce una riprogettazione tempestiva e efficace della segnaletica errata al fine di offrire una migliore esperienza utente
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
