«Ancora non ci ho capito niente di come funziona l’algoritmo»: la consapevolezza algoritmica degli host di Airbnb
No full textSulla scia dei recenti studi sulla consapevolezza algoritmica (Eslami et al. 2015; Gran et al. 2021), l’articolo propone un focus sul livello di questa consapevolezza (Gran et al. 2021) tra gli host di Airbnb. Lo studio si avvale di una etnografia digitale (Pink et al. 2016) che include un periodo di 4 mesi di osservazione non partecipante dei gruppi Facebook chiusi costituiti da host di Airbnb, dal 1° marzo al 30 giugno 2021, e 15 interviste semi strutturate con host di Airbnb residenti in Toscana e Sardegna. Dall’etnografia emerge che la consapevolezza algoritmica varia in base al livello di professionalizzazione degli host. L’opacità della governance algoritmica di Airbnb favorisce quindi un divario crescente tra host professionisti e host amatoriali, che si traduce in una distribuzione diseguale della visibilità degli annunci e dei benefici economici che gli host possono trarre da questa piattaforma.In the wake of recent studies on «algorithmic awareness» (Eslami et al. 2015; Gran et al. 2020), this article proposes a focus on the level of this awareness (Gran et al. 2020) among Airbnb hosts.
The study uses a digital ethnography (Pink et al. 2016) that includes a 4-month period of non-participant observation of closed Facebook groups formed by Airbnb hosts, from March 1 to June 30, 2021, and 15 semi-structured interviews with Airbnb hosts residing in Tuscany and Sardinia.
The ethnography shows that algorithmic awareness varies with the level of professionalization of hosts. The opacity of Airbnb’s algorithmic governance thus fosters a widening gap between professional and amateur hosts, which results in an unequal distribution of visibility and economic benefits that hosts can derive from this platform
Resistenza e solidarietà algoritmica nelle piattaforme digitali: un'indagine etnografica dei gruppi di engagement su Instagram
Get PDFIn this article, we show the complexity of the relationship existing between the power ofplatforms and the agency of users through the case study of engagement groups (pods)on Instagram, on which we carried out an eight-month digital ethnography (October 2019-May 2020) to understand the processes of meaning-making that take place within them.
Through the discussion of the ethnographic material generated during the eldwork.
we illustrate that this relationship is neither monolithic nor deterministic as many schol-ars have recently portrayed it. Although users of the platforms are bound to them byhighly asymmetrical power relations, there still seems to be a space for the exercise ofindividual agency, which, in the case that we studied, takes the form of the creationof a collective network of users who support each other and question the discursiverhetoric typical of Instagram, replacing it with an alternative moral code. We proposeto frame the activity of these groups as a form, albeit fragile, of «everyday» resistance tothe power and moral code of online platforms. Instagram pods are unable to subvert
the power exerted by platforms, but they represent the rst step, among many neces

sary ones, towards the construction of more structured forms of resistance in the eld
of emerging «platformised» cultural industries
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
