Facebook come strumento di studio e di lavoro
2014
La crescente diffusione dei social media sta cambiando profondamente il modo di fare comunicazione, anche per quanto riguarda la didattica universitaria. Per questo motivo occorre sviluppare nuovi modelli coerenti con gli stili di vita e i linguaggi delle nuove generazioni di studenti universitari. Considerando la grande possibilità, offerta dai social network, di reperire e condividere risorse (link utili, articoli, materiali audio o video, etc.), abbiamo potuto verificare che questi ambienti di per sé possono garantire agli studenti l’occasione di ampliare la propria conoscenza e il proprio livello di informazione, tanto da risultare proficui per l’apprendimento e sono stati un’ottima opp…
IMPATTO DELLA CHIMICA NELLA VITA QUOTIDIANA: UN PROGETTO DEL NETWORK EC2E2N 2
2013
Il progetto si pone come obiettivo la realizzazione di “Studi di Caso”, esemplificativi in aree in cui la Chimica ha un ruolo determinante e che dimostrino l’impatto di questa scienza nella vita quotidiana. Gli esempi scelti, dovranno essere specifici, attraenti e interessanti anche per un pubblico privo di basi scientifiche. Inoltre, si realizzeranno un certo numero di quesiti online, attraverso i quali il pubblico potrà anche valutare la propria consapevolezza di tale impatto.
Beyond good and evil: The impact of digital environment in family life
2019
Internet has changed the way we interact with others and has become an essential tool for daily activities. Children and adolescents are the main users of new digital technologies and their first contact with a screen happens increasingly earlier in life. Its premature use can be dangerous: technology represents a “supernormal stimulus” that can act on the brain reward circuit and affect neural development. In this article we describe the effects of technology on the brain, well-being, social and family relationships, highlighting both positive and negative ones: rather than defining a priori any type of technology as “good” or “bad”, we should consider how specific applications are used in…
Network interimpresa ed opportunità imprenditoriali: il ruolo dei legami deboli e forti nella formazione e nello sfruttamento delle opportunità impre…
2018
L'obiettivo del lavoro è indagare il ruolo dei legami deboli tra imprese nel processo di identificazione del set di potenziali partner di valore tra i quali scegliere con chi attivare legami forti, formalizzati in alleanze, che consentano di sfruttare opportunità imprenditoriali scoperte o create. Numerosi studi manageriali si sono soffermati ad analizzare l'emersione e le dinamiche evolutive della struttura dei network di alleanze ed hanno, complessivamente, individuato le differenti finalità e le logiche di formazione che contraddistinguono due categorie di legami forti: i legami locali che si formano all'interno di cluster appartenenti al network; i bridging ties, che creano ponti tra pa…
Political Identities Constructed on a Social Network: The Labour Party on Facebook Boards
2019
This paper is concerned with how an (institutional) political identity is constructed on a Social Network (SN) wall, which represents the political identity of the party as designed in digital interactive contexts, and where political image constructions are eventually accepted or negotiated by the digital audience. Like other political parties, the Labour Party resorts to online platforms for official accounts and political message dissemination (Gerbaudo 2014; Boyd 2014) and constructs its (online) identity. Since interaction is seen (Baumann 2000; De Fina 2011) as the most important locus for the production of identities, this study looks at Facebook boards as interactional sites where t…
Analysis of network rumor dissemination and control mechanisms on Chinese social network : Sina Weibo
2016
The social network has become a major source of information. The openness and swiftness of the network bring instant accessing to both true and false information. Sometimes the false information such as network rumors can mislead people from obtaining the true information and even create chaos. The social network platforms and the governments in different countries are making effort on enacting their own mechanisms to strive on eliminating the rumors. The aim of this thesis is to investigate the spreading of rumors on the Chinese social networking website Sina Weibo. The censorship policy of the Chinese government and the methods used to control the spreading of rumors are discussed. The la…
Du producteur à l'utilisateur: identification des trajectoires d'appropriation des données géographiques.
2009
To define, on a non technician face, the life cycle of geographic information, "from captor to decisions" we need, in a actor network theory perspective, to understand the process "from producer to user". In order to give an answer, we choose to study the spatial data appropriation process. This process opens the analysis of how data can be used by a group that has not produced the data itself, as well as in a multi-actor context. Distributed cognition theory offers a framework to understand data as a cognitive and collaborative artefact. Eight exploratory case studies help to identify typical appropriation trajectories, factors and socio-cognitive processes. This article offers a different…
Distributed optimal power flow for islanded microgrids: An application to the Smart Polygeneration Microgrid of the Genoa University
2016
In this work, the application of an original distributed optimal power flow method to test a microgrid in the Savona area, Italy is proposed. The microgrid shows different types of Distributed Energy Resources (DERs) and is connected to the main grid through a fixed power bus. Due to the high computational speed, the applied distributed Optimal Power Flow can be performed almost in real time, i.e. every 5 minutes or less. The operating solution found for generators, simply using local information, corresponds to a suboptimal condition with reduced losses, bus voltages and line currents within constrained intervals. The distributed optimization algorithm is iterative, but also fast. It is ba…
The role of expert evaluation for microsleep detection
2015
Abstract Recently, it has been shown by overnight driving simulation studies that microsleep density is the only known sleepiness indicator which rapidly increases within a few seconds immediately before sleepiness related crashes. This indicator is based solely on EEG and EOG and subsequent adaptive pattern recognition. Accurate microsleep recognition is very important for the performance of this sleepiness indicator. The question is whether expensive evaluations of microsleep events by a) experts are necessary or b) non-experts provide sufficient evaluations. Based on 11,114 microsleep events in case a) and 12,787 in case b) recognition accuracies were investigated utilizing (i) artificia…
Change Is Good, But Not Too Much: Dynamic Positioning in the Interfirm Network and New Product Development
2018
This research considers the dynamic positioning of an enterprise in an interfirm network and its propensity for new product development. Specifically, we explore how firms reconcile the dichotomy between central and structural holes network positions, by dynamically shifting from a central to a structural holes position (and vice versa) over time. By grounding this research in network dynamics theory, we argue how prior strong central (structural holes) network positions in the interfirm network increase the likelihood the firm will benefit from structural holes (central) positions in the following time period. We also propose that these positions can be modeled by an inverted U-shaped rela…
