Il capitale umano. Il lavoro delle audience nei connective media: tra user generated content (UGC) e professional generated content (PGC)
No full textIn the last decade, connective media has created new forms of digital economic circulation based
on disintermediation, cooperation, content creation and sharing, which have become fundamental
to everyday life and communication practices during a period of crisis.
Within this new scenario, digital disruption has generated new sharing experiences and realized
the regime of a gig economy. As a matter of fact, the “platform society” equates to that
of prosumer capitalism: digital circulation affects audience experience in terms of prosumption,
turning the users into potential content creators. Thanks to the pervasiveness and familiarity of
“connected media”, individuals may practice their creativity and experiment with their ability as
content producers.
The article aims to examine this transition with respect to a specific online platform, You-
Tube, where audiences continuously experiment with the condition of being both consumers and
producers, investing time and skills (i.e. digital labour) in an immaterial, collaborative work, ultimately
resulting in the shift from user generated content (UGC) to professional generated content
(PGC)
Szymborska e Herbert. Alcune considerazioni preliminari
No full textSzymborska and Herbert. Some Preliminary Considerations.
This paper presents a survey of thematic similarities and differences in the poetry of Szymborska and Herbert. The author analyzes their correspondence, published in 2018, which bears witness to their friendship, along with their differing biographies. A brief review of studies dedicated to the parallels between the two poets is also provided. The themes were similarities and differences between the two poets are observed include: classical antiquity, torture, the conception of ethics, and the existential suffering, as addressed by Syzmborska in her poem "Advertisement". In conclusion, the Author suggests that the poets' differing visions of poetics and existence are reflected in two formulas they choose to express their attitudes towards life: "I don't know" for Szymborska and "despite everything" for Herbert
NEUTRINO, γ-RAY, and COSMIC-RAY FLUXES from the CORE of the CLOSEST RADIO GALAXIES
No full textThe closest radio galaxies; Centaurus A (Cen A), M87, and NGC 1275, have been detected from radio wavelengths to TeV γ-rays, and also studied as high-energy neutrino and ultra-high-energy cosmic-ray (UHECR) potential emitters. Their spectral energy distributions (SEDs) show a double-peak feature, which is explained by a synchrotron self-Compton (SSC) model. However, TeV γ-ray measured spectra could suggest that very-high-energy γ-rays might have a hadronic origin. We introduce a lepto-hadronic model to describe the broadband SED; from radio to sub-GeV photons as synchrotron SSC emission and TeV γ-ray photons as neutral pion decay resulting from pγ interactions occurring close to the core. These photo-hadronic interactions take place when Fermi-accelerated protons interact with the seed photons around synchrotron SSC peaks. Obtaining a good description of the TeV γ-ray fluxes, first, we compute neutrino fluxes and events expected in the IceCube detector and, second, we estimate UHECR fluxes and the event rate expected in Telescope Array, Pierre Auger, and HiRes observatories. Within this scenario, we show that the expected high-energy neutrinos cannot explain the astrophysical flux observed by IceCube, and the connection with UHECRs observed by Auger experiment around Cen A might be possible only considering a heavy nuclei composition in the observed events
Brand identity/Personal identity. Processi di costruzione identitaria attraverso i brand sui Social Network Site
No full textInterrogarsi sul ruolo svolto dai consumi nei meccanismi di definizione dell’identità significa, oggi, cercare di fissare i confini di un territorio ancora per molti versi indefinito. Di certo, il passaggio dal bisogno al desiderio come motore del consumo segnala uno spostamento dell’attenzione da un oggetto-prodotto ad un soggetto-produttore di senso, sempre più capace di trasformare la propria l’identità in progetto attraverso scelte di consumo qualificate (Fabris, 2010). Nella pratica quotidiana, l’adesione ad uno stile di vita – per quanto provvisoria e flessibile – implica il consapevole relazionamento con un cluster di prodotti e di brand, che ogni soggetto declina in base alla propria personalità, alla propria sub-cultura e, sempre di più, alle proprie reti relazionali (sia off line che on line). Sempre più frequentemente attraverso l’ostentazione del rapporto con il prodotto/brand si comunica un’istanza di condivisione in grado di generare intesa e legame sociale.
Simili dinamiche trovano un’immediata applicazione nell’ambito dei SNS, ed è proprio dall’analisi dei post pubblicati dai gruppi dei fans di brand di successo che si intende partire, per cercare di verificare se la dimensione identitaria ed espressiva del consumo sia ormai prevalente su quella più strettamente legata al prodotto e alle sue qualità. Ciò che intendiamo osservare, in altre parole, sono le dinamiche di appropriazione dei brand da parte degli individui e i meccanismi di inclusione di determinati lovemarks (Roberts, 2006) tra le risorse identitarie cui i soggetti ricorrono per esprimere se stessi e sperimentare il proprio essere nel mondo
Le reti della comunicazione politica, tra televisioni e social networks.
No full textNello scenario contemporaneo, accanto alla crisi della comunicazione politica e delle tradizionali forme di partecipazione, hanno assunto rilievo la trasformazione dei formati e dei linguaggi della telepolitica e l'accesso sempre più generalizzato dei cittadini a piattaforme interattive, che li affrancano dal semplice ruolo di spettatori del discorso politico. Questo volume propone un percorso di riflessione e di ricerca mixed methods, validato nell'ambito del progetto «Contro la comunicazione politica. Ripensare la partecipazione nell'età dei vecchi e nuovi media» (PRIN 2007), con l'obiettivo di comprendere in quali modi la comunicazione politica stia utilizzando oggi l'ecosistema dei media e il ruolo di questo nuovo equilibrio mediale nella costruzione delle idee della politica e della partecipazione politica da parte dei cittadini
TeV γ-ray fluxes from the long campaigns on Mrk 421 as constraints on the emission of TeV-PeV neutrinos and UHECRs
No full textLong TeV γ-ray campaigns have been carried out to study the spectrum, variability and duty cycle of the BL Lac object Markarian 421. These campaigns have given some evidence of the presence of protons in the jet: (i) Its spectral energy distribution which shows two main peaks; one at low energies (∼1 keV) and the other at high energies (hundreds of GeV), has been described by using synchrotron proton blazar model. (ii) The study of the variability at GeV γ-rays and X-rays has indicated no significant correlation. (iii) TeV γ-ray detections without activity in X-rays, called "orphan flares" have been observed in this object. Recently, The Telescope Array Collaboration reported the arrival of 72 ultra-high-energy cosmic rays with some of them possibly related to the direction of Markarian 421. The IceCube Collaboration reported the detection of 37 extraterrestrial neutrinos in the TeV-PeV energy range collected during three consecutive years. In particular, no neutrino track events were associated with this source. In this paper, we consider the proton-photon interactions to correlate the TeV γ-ray fluxes reported by long campaigns with the neutrino and ultra-high-energy cosmic ray observations around this blazar. Considering the results reported by The IceCube and Telescope Array Collaborations, we found that only from ∼25% to 70% of TeV fluxes described with a power law function with exponential cutoff can come from the proton-photon interactions
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
Branding identity. Facebook, brands and self construction
No full textThe driving force of consumption has shifted from the need for something to the desire for it. This change
implies that we, as researchers, should pay attention to the relationship dynamics which link consumers
with certain products and brands - autonomously chosen according to the individuals’ personalities,
sub-cultures, and increasingly, to their offline and online relationships.
Such processes seem to be emphasized by Social Network Sites; in this chapter we analyze a sample of
posts published on Facebook by fans of successful brands, in order to try and understand if consumption
is more related to individuals’ identities and expressions or if it is still connected to the product
itself and its qualities. We will try to observe the dynamics of brand appropriation and the mechanisms
through which individuals include lovemarks (Roberts, 2006) among the identity resources they use to
express themselves and to experiment - with no substantial differences between mediated and face to
face relationships - their experience in the world
