RISULTATI RICERCA

In Italia la sicurizzazione residenziale costituisce un argomento ancora inesplorato. L’articolo presenta i risultati di una mappatura dei comprensori chiusi in Sardegna, realizzata attraverso l’analisi di annunci immobiliari e immagini satellitari. Nel contesto analizzato la presenza di insediamenti accessibili ai soli residenti è strettamente legata ai flussi turistici, con forti criticità in termini di impatto ambientale e di fruizione del territorio.

A computational laboratory is proposed for secondary school students to facilitate the learning process of the Infrared (IR) spectra of water and carbon dioxide. In the context of the greenhouse effect, which is the macroscopic phenomenon related to the rate of cooling of our planet in response of being warmed by the sun, students can learn its molecular origin with the support of computer through the simulation of the vibrational spectra of water and carbon dioxide. Input files as well as data are provided so that the laboratory can be proposed even when computational facilities are not available. In particular, the role of computer in chemistry teaching and learning is established because molecular models let the students visualize the subnanometric world which remains elusive in daily experience.

In questo breve lavoro si vogliono evidenziare le tecniche e le tecnologie criminalistiche che l’investigazione di polizia scientifica ha sviluppato e utilizza per la ricerca del dato, con particolare attenzione a quella che l’esigenza dello sviluppo tecnologico ha creato, e cioè la ri-cerca del dato digitale, che ha perso gran parte delle sue caratteristiche di materialità, diventando un segnale mobile in un sistema che non ha dimensioni di spazio e tempo, e che tende a espandersi il più velocemente possibile in una grande area multimediale e globalizzata. Verranno quindi esaminate brevemente le tecniche di ricerca e repertamento del dato digitale e lo sviluppo dei moderni metodi d’investigazione: la Digital Forensic. In particolare sia farà cenno alla Computer Forensic, dedicata alla ricerca e all’analisi del dato digitale su supporti hardware, alla Network Forensic, che si occupa delle reti sulle quali il dato digitale si muove e alle tecniche di Anti-Forensic, at-te a contrastare l’investigazione digitale.

The digital health technologies have gained dramatic levels of interest and offer potential for self-managed, at scale, cost effective e-mental health. In this discussion paper, we aim to outline some of the contemporary issues arising from the computer’s incursion in the field of psychiatry, as the global demand for improved mental wellbeing advances. The authors bring their personal reflections and areas of interest on the subject of e-mental health, taking into consideration both potential pitfalls and therapeutic possibilities. The paper outlines as an introduction what is meant by e-mental health and explores how it is being utilized in areas such as depression, anxiety management, alongside emergent outcome data on, for example, rates of admissions to hospital, as an initial measure of e-mental health’s success. Having undertaken a review of the published evidence from the past five years, it can be seen how the subject is gaining attention, yet results are as yet limited to small numbers, and thus there is a limited evidence base. However, we also consider the implications for inclusion, through the application of e-health strategies for people living with additional neurological aspects such as intellectual disabilities, which as a population tends to limit uptake and exposure to online digital activity to date. We conclude with consideration of two critical questions on how to monitor, evaluate and regulate e-mental health activities, plus the ethical implications of e-exposure.

L’applicazione dei metodi formali per l’analisi di programmi reattivi che simulano i comportamenti di sistemi cellulari in biologia computazionale è presa in esame per gettare nuova luce sugli approcci simulativi in Intelligenza Artificiale e Vita Artificiale. In primo luogo, si sottolinea come i programmi che simulano i comportamenti di molti sistemi reattivi cellulari sono più proficuamente esaminati per mezzo di modelli eseguibili delle esecuzioni del programma simulativo. Tali modelli risultano essere rappresentazioni sia del programma simulativo che del sistema cellulare simulato. In secondo luogo, si evidenzia come i processi di scoperta di comportamenti di interesse del sistema simulato vengano effettuati attraverso verifiche algoritmiche condotte sul modello formale che rappresenta i fenomeni biologici di studio. Infine, un tratto metodologico distintivo dell’attuale biologia computazionale viene riconosciuto nel fatto che le ipotesi avanzate sulla base di modelli eseguibili non sono confermate o falsificate testando il programma simulativo, il quale non viene nemmeno codificato, ma effettuando esperimenti in vitro finalizzati ad osservare i comportamenti del sistema naturale corrispondenti ai percorsi del modello che soddisfano o violano le ipotesi in corso di valutazione

Computer-expertise, computer self-efficacy e Internet attitude come fattori che predicono l’ansia da computer. Una ricerca su un gruppo di docenti del territorio palermitano - Computer-expertise, computer self-efficacy and Internet attitude were analyzed as predictors for computer-anxiety in a population of 77 Italian teachers. Results at a multiple regression analysis showed that only low computer self-efficacy predicts anxiety toward computers, whereas this is not the case of low computer-expertise or low Internet attitude. Such outcomes suggest the possibility to design training or psychological treatments aimed at modifying negative perceptions toward computers of techno-stressed people more than increasing their effective computer expertise or feelings toward the Internet. Keywords: Computer-expertise, Internet attitude, Computer-anxiety.

According to the dominant formal model in cognitive sciences, cognitive operations are computational and the brain mechanisms that enact them are seen as analogous to those of a computer. Such a model has been criticized from different perspectives: for some it lacks semantics, while for others it is a static or inadequate model, even a ‘failed program’. But many of these critics are based on an often-oversimplified conception of Turing’s original computing machine, whose sole objective was to imitate ‘computors’, i.e. humans ‘calculating with pencil and paper’. Since this first presentation, Turing himself as well as later scholars have contributed to the refining of the computational model behind the functioning of this machine. However, many of these highly technical modifications were left out in the cognitive appropriation of this model. By revisiting Turing’s original machine as well as its theoretical developments, the present paper aims to shed new light on the computational issues related to cognitive models.

The article discusses the role of food as an instrument of identity and a channel of contact through cultures. This is argued drawing from the food practices of international migrants in the context of the global flows of people and commodities in present day Italy. In this regard, food plays an essential role in the rebuilding of a familiar context in which migrants can feel temporarily "at home". At the same time, food is an important form of communication and contact between different cultures and social contexts. In this process of exchange both migrants and hosts, food habits and diets are modified as they incorporate elements and ingredients from each other, making more porous the boundaries of difference.
