Did We Miss the Social Commentary? Responding to Borat on Youtube

2011

Ever since the fictitious Kazakh journalist Borat Sagdiyev became an icon of contemporary popular culture, many questions have arisen about the reception of Borat by the general public. Namely, how common people have created a shared representation of Borat and how the complicated character and comedic manner undertaken by Sacha Baron Cohen is being deciphered. To address these questions that, surely, also could be asked concerning other international media products, this article deals with the reception of Borat the character on YouTube. In particular, the viewers’ reaction to the YouTube video titled “The Best of Borat” is analysed. This video has been viewed more than seven million times…

Enhancing Privacy and Authorization Control Scalability in the Grid through Ontologies

2009

The use of data Grids for sharing relevant data has proven to be successful in many research disciplines. However, the use of these environments when personal data are involved (such as in health) is reduced due to its lack of trust. There are many approaches that provide encrypted storages and key shares to prevent the access from unauthorized users. However, these approaches are additional layers that should be managed along with the authorization policies. We present in this paper a privacy-enhancing technique that uses encryption and relates to the structure of the data and their organizations, providing a natural way to propagate authorization and also a framework that fits with many u…

Designing Classroom Practices for Teaching Online Inquiry : Experiences from the Field

2021

Students face several challenges when asked to locate relevant and credible information from the internet. This article introduces three principles for designing online inquiry lessons and documents what we learned from five language arts teachers from Finland who implemented and provided feedback on a learning unit framed in those design principles. Teachers implemented a researcher-designed online inquiry unit in nine upper secondary school classrooms. The unit included four 75-minute lessons sequenced to support the location, evaluation, and synthesis of information students encountered in an online inquiry task. Teachers’ diaries revealed their impressions of the unit, problems encounte…

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

Metal-Organic Frameworks as Versatile Heterogeneous Solid Catalysts for Henry Reactions

2021

Metal–organic frameworks (MOFs) have become one of the versatile solid materials used for a wide range of applications, such as gas storage, gas separation, proton conductivity, sensors and catalysis. Among these fields, one of the more well-studied areas is the use of MOFs as heterogeneous catalysts for a broad range of organic reactions. In the present review, the employment of MOFs as solid catalysts for the Henry reaction is discussed, and the available literature data from the last decade are grouped. The review is organized with a brief introduction of the importance of Henry reactions and structural properties of MOFs that are suitable for catalysis. The second part of the review dis…

How to standardize (if you must)

2017

In many situations we are interested in appraising the value of a certain characteristic for a given individual relative to the context in which this value is observed. In recent years this problem has become prominent in the evaluation of scientific productivity and impact. A popular approach to such relative valuations consists in using percentile ranks. This is a purely ordinal method that may sometimes lead to counterintuitive appraisals, in that it discards all information about the distance between the raw values within a given context. By contrast, this information is partly preserved by using standardization, i.e., by transforming the absolute values in such a way that, within the s…

Object Recognition and Modeling Using SIFT Features

2013

In this paper we present a technique for object recognition and modelling based on local image features matching. Given a complete set of views of an object the goal of our technique is the recognition of the same object in an image of a cluttered environment containing the object and an estimate of its pose. The method is based on visual modeling of objects from a multi-view representation of the object to recognize. The first step consists of creating object model, selecting a subset of the available views using SIFT descriptors to evaluate image similarity and relevance. The selected views are then assumed as the model of the object and we show that they can effectively be used to visual…

Tandem cross enyne metathesis (CEYM)–intramolecular Diels–Alder reaction (IMDAR). An easy entry to linear bicyclic scaffolds

2015

A new tandem cross enyne metathesis (CEYM)–intramolecular Diels–Alder reaction (IMDAR) has been carried out. It involves conjugated ketones, esters or amides bearing a remote olefin and aromatic alkynes as the starting materials. The overall process enables the preparation of a small family of linear bicyclic scaffolds in a very simple manner with moderate to good levels of diastereoselectivity. This methodology constitutes one of the few examples that employ olefins differently than ethylene in tandem CEYM–IMDAR protocols.

Cultural institutions as agents of urban and community regeneration in the (post-)pandemic city. The case of the «Laboratorio Zen Insieme» in Palermo

2022

Although all cities in the world have been affected by the COVID-19 pandemic, its impacts on the territories, yet to be understood, are unevenly distributed, revealing extremely varied imbalances depending on the places. However, it is clear that the virus and its variants have aggravated pre-existing socio-spatial inequalities, creating new ones and bringing attention back to those implications between space, planning, public health and citizenship that are at the origins of contemporary urbanism. In a reference framework in which the crisis is globalized but unequal and in the absence of a welfare system capable of responding to the urgencies of the most marginalized social contexts and g…

Olsen 2018Settore ICAR/21 - UrbanisticaSettore M-GGR/01 - GeografiaSacco and Blessi 2009). In the current (post-) pandemic context and through the lens of a southern European perspective the purpose of this article is to critically reflect about the role of culture as possible vehicle of urban and community regeneration. In particular we will focus on the activities of the no profit organization «Laboratorio Zen Insieme» in ZEN2 one of the last large popular and peripheral neighborhoods built in Palermo at the end of 80s in order to explore and understand how cultural practices work as agent of urban and social transformation capable of addressing emerging issues especially in the pandemic scenario we are experiencing. Thecasestudy has been conducted through analysis of documents participative observations (Honer and Hitzler 2015) and qualitative in-depth interviews with key actors involved in the conception organization and management of the activities carried out by Laboratorio Zen Insieme with representatives of local institutions and non-formal conversations with participants of the workshops heldin the neighborhood. The experience we narrate finds that cultural practices have re-conceptualized their design and functions as strategies of urban and community regeneration and at the same time have contributed to answer to emergent issues in developing proximity and local based strategies facing up to problems inherent civil rights educationalpoverty socio-spatial justice and have changed the image and identity of urban places they inhabit.In this sense the research provides a framework for development of strategies and legitimization for cultural practices and a point of discussionabouttheirrolein urban development.Although all cities in the world have been affected by the COVID-19 pandemic its impacts on the territories yet to be understood are unevenly distributed revealing extremely varied imbalances depending on the places. However it is clear that the virus and its variants have aggravated pre-existing socio-spatial inequalities creating new ones and bringing attention back to those implications between space planning public health and citizenship that are at the origins of contemporary urbanism. In a reference framework in which the crisis is globalized but unequal and in the absence of a welfare system capable of responding to the urgencies of the most marginalized social contexts and groups a response to the new social and individual needs has been offered by cultural institutions that play a role of territorial agency often independently or in the absence of political institutions. Far from the idea of entertainment and divertissement it is in fact increasingly clear how the practices of cultural innovation experimenting with various forms of action and participation can in some cases play a fundamental role in the processes of social cohesion and community building representing an antidote to the worsening of the phenomena of marginalization and socio-spatial inequalities within cities and territories (Colantonio and Dixon 2011
