Could the recent zika epidemic have been predicted?

2017

AbstractGiven knowledge at the time, the recent 2015-2016 zika virus (ZIKV) epidemic probably could not have been predicted. Without the prior knowledge of ZIKV being already present in South America, and given the lack of understanding of key epidemiologic processes and long-term records of ZIKV cases in the continent, the best related prediction was for potential risk of an Aedes-borne disease epidemic. Here we use a recently published two-vector capacity model to assess the predictability of the conditions conducive to epidemics of diseases like zika, chikungunya or dengue, transmitted by the independent or concurrent presence of Aedes aegypti and Aedes albopictus. We compare the potenti…

Viaggi nell’immaginario: il turismo virtuale nel sito UNESCO di Tarragona

2023

Le nuove tecnologie hanno trasformato in modo radicale non solo la geografia come disciplina, ma anche le geografie del mondo. Il digitale ha assunto, infatti, un ruolo di mediazione sempre più pervasivo nella produzione dello spazio, come delle conoscenze e degli immaginari geografici. Le possibilità offerte dal virtuale, in particolare, offrono oggi un contributo decisivo nella comunicazione dei significati attribuiti ai luoghi e rispondono in modo sempre più efficace ai bisogni emergenti del settore turistico. Le esperienze di visita mediate dal digitale mirano a coinvolgere i sensi e risultano efficaci quando promuovono immersioni rigorosamente realistiche. Nel quadro di queste riflessi…

New technologies have radically transformed not only geography as a discipline but also the geographies of the world. Indeed the digital has assumed an increasingly pervasive mediating role in the production of space as of geographic knowledge and imaginaries. The possibilities offered by the virtual in particular now offer a decisive contribution in communicating the meanings attributed to places and respond increasingly effectively to the emerging needs of the tourism sector. Digitally mediated visitor experiences aim to engage the senses and are effective when they promote rigorously realistic immersions. Within the framework of these reflections the paper highlights the renewed relevance of authenticity both of the tourism experience and of cultural heritage in relation to its potential for attraction and proposes a contextualization of the theme in light of the unprecedented opportunities granted by technologies for the creation of virtual and augmented spaces. The proposed discussion is therefore also a journey aimed at exploring authenticity as a tool through which new technologies can effectively mediate a sense of place and foster brand communication of a destination. The case study is the UNESCO site of Tarragona whose most relevant image for urban policies is presented. This shared figuration spatially defined and rooted in a precise historical moment is reconstructed on the one hand through the analysis of functional documentation for the candidacy and on the other by means of a review of mobile applications developed for the promotion of the city's cultural heritage. The proposed journey and exploration of the place return in light of the research data and in conclusion the central role played by digital technologies in mediating the UNESCO imaginary. The forms of virtual tourism in Tarragona confirm that to travel is to experience a text enveloped in time and inscribed in space.Settore M-GGR/01 - Geografia

Seagrass ecosystem response to long-term high CO2 in a Mediterranean volcanic vent

2014

We examined the long-term effect of naturally acidified water on a Cymodocea nodosa meadow growing at a shallow volcanic CO2 vent in Vulcano Island (Italy). Seagrass and adjacent unvegetated habitats growing at a low pH station (pH = 7.65 ± 0.02) were compared with corresponding habitats at a control station (pH = 8.01 ± 0.01). Density and biomass showed a clear decreasing trend at the low pH station and the below- to above-ground biomass ratio was more than 10 times lower compared to the control. C content and delta 13C of leaves and epiphytes were significantly lower at the low pH station. Photosynthetic activity of C. nodosa was stimulated by low pH as seen by the significant increase in…

Probabilistic Fuzzy Approach to Evaluation of Logistics Service Effectiveness

2014

Received: 9 September 2014 Abstract Accepted: 11 October 2014 Logistics service providers offer a whole or partial logistics business service over a certain time period. Between such companies, the effectiveness of specific logistics services can vary. Logistics service providers seek the effective performance of logistics service. The purpose of this paper is to present a new approach for the evaluation of logistics service effectiveness, along with a specific computer system implementing the proposed approach – a sophisticated inference system, an extension of the Mamdani probabilistic fuzzy system. The paper presents specific knowledge concerning the relationships between effectiveness i…

Ground and excited state charmonium production inp+pcollisions ats=200  GeV

2012

We report on charmonium measurements [J/psi (1S), psi' (2S), and chi(c) (1P)] in p + p collisions at root s = 200 GeV. We find that the fraction of J/psi coming from the feed-down decay of psi' and chi(c) in the midrapidity region (vertical bar y vertical bar < 0: 35) is 9.6 +/- 2.4% and 32 +/- 9%, respectively. We also present the p(T) and rapidity dependencies of the J/psi yield measured via dielectron decay at midrapidity (vertical bar y vertical bar < 0.35) and via dimuon decay at forward rapidity (1.2 < vertical bar y vertical bar < 2.2). The statistical precision greatly exceeds that reported in our previous publication [Phys. Rev. Lett. 98, 232002 (2007)]. The new results are compare…
