Beyond Hunting Camps: Early Holocene Occupations in High Cantabrian Mountains (Spain)
1998
En la comunicación se presentan los resultados de las excavaciones en el abrigo de La Calvera (Camaleño, Cantabria) incluyendo un conjunto de nuevas dataciones radiocarbónicas y se hace una reflexión sobre la ocupación de las montañas cantábricas al comienzo del Holoceno. In the communication the results of the excavations in La Calvera rock shelter (Camaleño, Cantabria) are presented, including a set of new radiocarbonic dates and a reflection is made on the occupation of the Cantabrian mountains at the beginning of the Holocene.
The Romanian Academic Novel and Film through the Postcommunism/Postcolonialism Lens
2019
The last two decades have witnessed an intensified academic interest in a potential rapprochement between Postcolonial Studies and Postcommunist Studies, the former a firmly established discipline in global academia, while the existence of the latter as a discipline in its own right is still debatable. As the possibility of this alliance is – as was to be expected – both contested and supported by various scholars, this article attempts to investigate this issue as illustrated by the postcommunist Romanian academic novel. Aware as it is of contemporary intellectual debates, the genre of the academic (or campus) novel seems particularly suitable for shedding light on the matter: academic fic…
Second order nonlinear optics in AlGaAs metasurfaces
2023
Recently, nonlinear optics at the nanoscale level has emerged as a promising branch of nanophotonics. In this work, we focus our attention on Aluminum Gallium Arsenide (AlGaAs) nanoantennas and metasurfaces for efficient and controlled second harmonic photon emission. After a brief introduction concerning the main studies in this field, we present the latest results achieved in AlGaAs platforms both in the lossless and absorption regimes.
Fundamental limits for transmission modulation in VO2 metasurfaces
2022
The interest in dynamic modulation of light by ultra-thin materials exhibiting insulator–metal phase transition, such as VO 2 , has rapidly grown due to the myriad industrial applications, including smart windows and optical limiters. However, for applications in the telecommunication spectral band, the light modulation through a thin VO 2 film is low due to the presence of strong material loss. Here, we demonstrate tailored nanostructuring of VO 2 to dramatically enhance its transmission modulation, reaching a value as high as 0.73, which is 2 times larger than the previous modulation achieved. The resulting designs, including free-topology optimization, demonstrate the fundamental limit i…
Manipulating Light with Tunable Nanoantennas and Metasurfaces
2022
The extensive progress in nanofabrication techniques enabled innovative methods for molding light at the nanoscale. Subwavelength structured optical elements and, in general, metasurfaces and metamaterials achieved promising results in several research areas, such as holography, microscopy, sensing and nonlinear optics. Still, a demanding challenge is represented by the development of innovative devices with reconfigurable optical properties. Here, we review recent achievements in the field of tunable metasurface. After a brief general introduction about metasurfaces, we will discuss two different mechanisms to implement tunable properties of optical elements at the nanoscale. In particular…
Theoretical Approaches on Successful Email Marketing Campaigns
2016
Nowadays, the consumer has extremely varied product options. E-mail marketing could be atool to complement traditional marketing activities by increasing customer engagement, and whichdoes not involve high costs. While there have been many predictions for years that email marketing will be replaced withsomething else, it remained one of the most useful ways to reach current and potential customers. This paper aims to bring some clarifications on what could bring success to email marketingcampaigns. Responses are related to how sent emails can draw the attention of people (ie how theycan be observed), given that, users’ inboxes are invaded by messages of all kinds, how to measurethe results …

Manuali, «fieldwork», migranti. Passi per un’antropologia semiotica delle culture
2005
A partire da una riflessione sul ruolo determinante che i processi di testualizzazione svolgono in etnoantropologia si è inteso in questo contributo mettere l’accento su tre nozioni chiave, per il riorientamento della disciplina, quali quelle di ‘manuale’, ‘fieldwork’, ‘migrante’. Le tre nozioni sono state individuate sulla base di una concezione semiotica dell’antropologia secondo cui l’interrelata conoscenza di sé e degli altri non può fare a meno di una parallela disamina dell’interfaccia segnico e della simmetrica proiezione dei soggetti nel mondo fenomenologico dell’esperienza. L’analisi delle tre nozioni in oggetto è risultata essere rivelatrice di alcuni orientamenti ancora esotizzan…
Campi di forza. Percorsi confinati di migranti in Europa
2009
È impossibile comprendere la specificità delle attuali politiche europee di controllo delle migrazioni, senza confrontarsi con il grande tema dei luoghi di confinamento, in cui centinaia di migliaia di persone vengono oggi costrette semplicemente perché sprovviste di un regolare documento di soggiorno. Che si tratti di centri di detenzione istituzionali e militarizzati o di zone di concentramento informali, oppure nate spontaneamente, i luoghi qui analizzati sono tutti espressione del medesimo tentativo di governo della mobilità dei migranti, che ormai da diversi anni l’Unione europea sta praticando. Le radici dell’attuale sistema europeo di separazione di alcuni “corpi” dal resto della pop…
