La piattaformizzazione della serialità complessa. Ecosistemi narrativi transmediali nel platform ecosystem
Full text linkL’obiettivo di questa ricerca è comprendere la relazione tra l’ecosistema delle piattaforme e gli ecosistemi narrativi seriali, prendendo come caso di studio le serie originali prodotte da Facebook e Youtube, osservando il sistema distributivo, i contenuti e la reazione da parte del pubblico.
L’avvento delle tecnologie digitali ha cambiato l’epistemologia del panorama mediale, aprendo la strada alle piattaforme, definite come una serie di relazioni che devono essere costantemente performate su architetture digitali programmabili, volte a organizzare gli scambi tra utenti (Van Dijck 2013), i cui elementi fondanti sono la datafication, commodification e selection (van Dijck et al. 2018).
Le piattaforme facilitano e controllano le connessioni tra distinti gruppi di utenti al fine di monetizzare dati e attenzione degli utenti, cambiando così i modelli di business, in favore di un mercato più globalizzato e multiside (Rieder & Sire 2014): in particolare, le super-piattaforme, che non agiscono in un solo settore, stanno accentrando sempre più funzioni nel proprio ecosistema formato da differenti canali, servizi e contenuti, rendendo adatti ai sistemi piattaforma sempre più elementi e ambiti.
La serialità è uno dei contenuti profondamente trasformati dalla piattaformizzazione: il genere narrativo è diventato sempre più complesso e strutturato anche grazie alle possibilità delle tecnologie internet-based. I racconti seriali sono passati da essere prodotti monomediali, a universi transmediali, fino a trasformarsi in ecosistemi narrativi, ovvero sistemi aperti, in equilibrio, resilienti, dalle strutture interconnesse, dichiarativi e con componenti biotiche e abiotiche (Pescatore 2018).
La domanda a cui questo studio vuole rispondere riguarda le innovazioni apportate dalle super-piattaforme Facebook e YouTube alla produzione e distribuzione della serialità, oltre a comprenderne l’impatto sulle audience.
L’analisi si svolge su tre diversi livelli. Il primo, tecno-strutturale, osserva l’architettura delle sezioni dedicate a tali prodotti seriali, attraverso una griglia di analisi composta dagli elementi di datafication, commodification e selection (van Dijck et al. 2018). Il secondo, contenutistico, analizza una serie originale Facebook e una YouTube, cercando di comprenderne affinità e differenze con i tratti caratteristici degli ecosistemi narrativi, attraverso una nuova griglia di analisi che utilizza come categorie le caratteristiche osservate da Pescatore (2018). Per ultimo, si è avviata una ricerca esplorativa sull’impatto di tali sistemi e prodotti sugli utenti: è stato prima sottoposto un questionario a 700 fan di prodotti seriali, selezionati attraverso un campionamento a scelta ragionata, seguito da interviste semistrutturate a quattro soggetti compilatori del questionario.
I risultati hanno suggerito una crescente piattaformizzazione e transmedialità mono-ambientale dei prodotti diffusi dalle superpiattaforme, le quali utilizzano le affordances delle piattaforme già
integrate, mentre le narrazioni risultano essere sempre più ecosistemiche e partecipative. Dal questionario e dalle interviste, però, si nota come esse non sempre vengano partecipate da parte degli utenti proprio a causa di dinamiche proprie di tali social network e ben radicate nei sistemi, oltre a una scarsa campagna di promozione delle serie Originals da parte dei produttori. Il fenomeno è tutt’ora in evoluzione e la presente indagine esplorativa necessiterà di ulteriori osservazioni in base alle evoluzioni di prodotti e sistemi
Hardware in the loop implementation of the oscillator-based heart model: A framework for testing medical devices
Full text linkThe hardware in the loop technologies allow to simulate physical models in combination with real devices in order to validate the behavior of the latter under different conditions, not easily reproducible in the real world. They are widely used in various industrial applications. In this work we want to extend the methodology to medical devices. These must interact with the patient to obtain the desired clinical result, however, during the development and validation phase of medical devices, the patient cannot be involved in the testing process. In this article the hardware in the loop methodology is proposed starting from a mathematical model of the heart, based on oscillators, that can be used to validate pacemakers or other medical devices
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
