Patrimonio architettonico e spazi touristici. New life Tourism nella strategia dei sistemi locali
No full textSi tratta di una breve riflessione sulla necessità di verificare il significato integrato di patrimonio architettonico e spazio turistico, due ambiti che pur essendo strettamente correlati nella fruizione, troppo spesso non vengono assimilati nelle politiche urbane e urbanistiche, regionali e nazionali in un approccio geoterritoriale e strategico nel contesto globale. In luoghi concepiti e creati nell'ambito di ispessimenti storici la riflessione mette a fuoco il contributo del turista ormai sempre culturale e per questo più presente e partecipe alla costruzione del sistema locale
THE URBAN DEVELOPMENT OF RELIGIOUS TOURISM DESTINATIONS BETWEEN SACRED AND PROPHANE: THE CASES OF LOURDES AND SAN GIOVANNI ROTONDO
No full textThe current historical phase of uncertainty and social, economical and political instability constitutes the scenario for the increasing appeal and demand for religious and spiritual experiences. The constant growth of pilgrimages and religious trips seems to forecast some promising chances for local systems to trace a path out of the crisis, allowing this way several locations to develop or to propose themselves as religious tourism destinations. Nevertheless, as known, the turn-up of tourist loads challenges other aspects which go far beyond the mere economical aspect, stressing the identity of the local community and the geographical framework as well. The perception of Tourism as a panacea free from negative effects is quite outdated: a careful weighting of the possible scenarios for each specific context is necessary.
Religious tourism and pilgrimage are generated, led and moved by faith and spiritual needs. Nevertheless, they have secular implications which sometimes may dramatically conflict with the nature of the pilgrim and tourist activity itself, especially for what concerns the physical space. The pilgrim-tourist flow and human load impact directly on the urban space (urban range) and local community (tourism index), influencing, urban development, territorial infrastructures and landscape changes, land use and consumption, logistic matters, business and commerce, political decisions, interaction between stakeholders and so on. Moreover, some ideological dilemmas are entered by religious tourism becoming massive: how to combine the right for the faithful to perform his/her devotion with the local carrying capacity limits? Which kind of ethical and actual conflicts can spark from the interests related to the religious tourism business within the community? What is the relationship between religious power and secular authority in the management of such frameworks? Is the pilgrim-tourist becoming more and more a new, de-differentiated traveler figure?
This paper aims at exploring religious tourism destinations through a holistic approach. The different motivations and effects of religious tourism and pilgrimage on communities will be analyzed, using urban planning and territorial management as key to the reading of geographical effects and dynamics. The research will present two study-cases : Lourdes (France) and San Giovanni Rotondo (Italy), two of the major destinations for Christian pilgrimage and religious tourism in Europe. Both locations have in common the origin as humble rural villages and derive their rapid development from mystic events and the devotional rituals which followed, becoming this way destinations for the solely religious travels. The comparison between the study-cases will highlight the different approach held by the two communities, focusing in particular on the territorial strategies of development, techniques and tools adopted for urban planning, environmental policies, role of the architectural interventions in the regulation of rituals and worship, ways of involvement and participation of the local community and stakeholders, relationship between religious and secular institutions in the territorial and economical management. The reconstruction of such frameworks aims at contributing to the current debate around the sustainable religious tourism by drawing possible perspectives, practices and challenges for the virtuous management of devotional places as religious tourism destinations
Defects studies towards more-radiation-tolerant Silicon Photomultipliers
No full textSilicon photomultipliers (SiPMs) are single-photon sensitive large-area detectors widely used in many applications. Among them, they are used in several radiation-harsh applications, like high-energy physics and experiments in space, where they receive a significant radiation dose. The effect of ionizing and non-ionizing radiation dose on their performance is very interesting for those applications.We irradiated several Silicon Photomultipliers with protons and X-ray. We investigated the noise increment and directly compared per performance worsening on several SiPM technologies produced sat FBK (Trento, Italy). We also characterized the temperature dependence of the noise down to cryogenic levels, extracting the activation energy. We investigated in depth the defects created by protons within the microcells of the SiPMs, with emission microscopy measurements. We also investigated the effect of ionizing-energy-loss in the SiPM microcells, showing a relevant effect of charge accumulation in the dielectrics and in the trenches. Some technologies demonstrated a worse radiation tolerance with an internal modification of electric fields that increases the primary noise and afterpulsing. This have been directly confirmed with a dedicated irradiation campaign comparing SiPMs with different materials inside the deep trenches between microcells.All these considerations are useful to develop new SiPM technologies that are more radiation hard, both in terms of bulk damage and ionizing-energy-loss effects
"A Low-Voltage High-Drive Differential Amplifier For ISDN Applications,"
No full textA CMOS differential buffer amplifier for ISDN applications is reported. The chip operates from a
single 5 V power supply and can deliver a 6 Vpp 80 kHz signal into a load of 100 ohm and/or 300 pF
with a THD of about 0 25 % The circuit main feature is its PSRR which remain practically constant
from de to several hundred kHz around -75 dB for both positive and negative supplies with the
common mode voltage generated ou chip. The step response at % for the same loading conditions
is less than 500 nsec for a step of +1.51' and less than 1 ßsec for a step of -f-GV. By using relatively
small devices at the output the amplifier occupies an area of only 1720 square mils in a 2.5 ¡mi n-well

Practical Aspects in mCSEM Migration
No full textIt is widely known that the main framework for mCSEM imaging is the mathematical inversion of data,
that in real applications (thus 3D model geometries) require great computational resources to be
accomplished in reasonable time. It is also known from literature that non-inversion based imaging,
through migration algorithms, both iterative or not, are feasible with a computational cost far lower with
respect to inversion, although yielding images of resistivity contrasts or an apparent resistivity, but not a
reliable resistivity estimation and associated uncertainty. Here some practical aspects of one-pass mCSEM
migration and suggestions for some imaging improvement are analyzed
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
The Digital Storytelling Methodology In Media Education For Learning Digital Citizenship Skills As Part Of A University Course
No full textThis study investigates how a group of university students perceived their actual
achievement of a series of media, digital and critical reflection skills together with
critical reflection (information, media and digital literacy) developed during a Media
Education Workshop conducted through the use of Digital Storytelling techniques. The
study carried out at the University saw the participation of 176 students of the average
age of 21 who live within an "Infosphere", i.e. an eco-system dominated by media
frameworks and a continuous flow of information (a mediatization context). In this
workshop, the students were organised into workgroups and they designed 76 videos
that were published on the Network. Four thematic areas were addressed: digital life,
the environment, volunteering, the association movement and active citizenship. At the
end of the activities, the students were presented with a questionnaire that analysed
their perception of the effectiveness of Digital Storytelling in the development of digital
and media skills from various perspectives; in particular, critical thinking on concrete
and experiential issues. The quantitative and correlational assessment was conducted
on the basis of an initial hypothesis that the Digital Storytelling approach enables
participants to learn both technical skills in the use of digital tools (video in particular)
and also reflective practice and meta-cognition skills, thus stimulating awareness and
recognition of the students' ethical, social and value-related dimensions as well as
their contextual meaning
Variations on the Author
Full text link“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
Full text linkWe 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
