Il nucleo della sociologia internazionale è rappresentato dal ral rapporto di società civile e relazioni internazionali. In tale rapporto diventano importanti le seguenti variabili: società tradizionale e società moderna, organizzazioni, disordine tra società civile e società politica
Contemporaneità e tradizione nelle simbologie del territorio: il contributo sociologico di Franco Demarchi
No full textSi tratta della descrizione del percorso effettuato con il gruppo promosso da Franco Demarchi sui beni culturali sul territorio. I beni culturali sono una testimonianza indispensabile per comprendere l’attuale società e per comprenderne lo sviluppo futuro. Gli artefatti sono, infatti strumenti della conoscenza sociologica in quanto risultato di collaborazione e di contrattazione, frutto di motivazioni complesse e termine di valutazione morale ed economica diversificata a seconda delle condizioni sociali. I beni culturali rappresentano l’aspetto tangibile della collettività, tanto che la memoria e l’identità sono i tramiti delle dimensioni simboliche dei gruppi umani che presentano diverse modalità di fissazione e di circolazione. I risultati ottenuti dalle ricerche svolte da all’interno del gruppo di ricerca sono state molto importanti per definire l’esistenza di un consenso abbastanza omogeneo e unanime nel definire gli elementi di preferenza e di gradimento.. Demarchi aveva la convinzione che l’importanza dei beni culturali supera la volontà dell’artista e non sempre nel fruitore è presente la consapevolezza di che cosa essi sono. Tuttavia essi possono essere considerati testimonianze dell’itinerario di una provvidenziale civiltà, ma possono essere considerati anche promotori di questo cammino
Simulation of a molecular QCA wire
No full textMolecular Quantum Dot Cellular Automata (MQCA) are among the most promising emerging technologies for the expected theoretical operating frequencies (THz), the high device densities and the non-cryogenic working temperature. In this work we simulated a molecular QCA wire, based on a molecule synthesized ad-hoc for this technology. The results discussed are obtained by means of iterative steps of ab-initio calculation
The dolor, ira and Vengeance Cycle in Paul the Deacon’s Historia Langobardorum
No full textThis essay explores the role and meaning of the emotional term dolor in the scenarios of vengeance represented by the Lombard scholar Paul the Deacon (c.720–799) in his work Historia Langobardorum. First, after contextualising the work and analysing the concept of aristocratic honour and vengeance outlined by the author in the text, this essay examines the episodes in which dolor is associated with revenge. Second, starting from the work itself, the paper constructs the emotional script of dolor, namely the little scenario that a character plays out – as sequences of events, actions and social interactions – when he or she feels this emotion. Finally, it examines how the author evaluates dolor positively or negatively in relation to social and gender norms
The seismic risk in Istanbul: An innovative assessment method
No full textOver the last century, an unprecedented settlement expansion, generated by an exceptional world population growth, has made cities all around the world always more prone to disasters. Natural phenomena, such as earthquakes, could be potentially more dangerous when hit megalopolis and their neighborhoods particularly fragile. Amid the most important global cities, Istanbul is characterized by one of the highest levels of seismic risk. Within its territory, there are numerous highly vulnerable neighborhoods. Some of them are located around Ä°stiklal Caddesi, famous pedestrian street, which is being visited by a great number of people (both Turkish city-users and international tourists) twenty-four hours a day, seven days a week. Part of the old and historical neighborhood of Pera/Galata, in the today's BeyoÄŸlu Belediyesi, it is a highly attractive zone full of economic activities, acting as heart of the city. Since the importance of this area, its specific seismic risk has been assessed using two different approaches, one traditional and one proposed by the author, which have provided two different responses. The "standard method", based on generic variables applicable to the whole Istanbul Metropolitan Municipality, shows how this zone is not amongst the most risky area of the city. Whereas, "the experimental method", calibrated on more precise information and more specific variables typical of the case study area, demonstrates that the level of seismic risk is significant. Finally, a scheme of urban/district emergency evacuation system is here proposed indicating some shelter areas and classifying the streets, inside the case study area, according to their level of safety
Work-in-progress: MicroElectronics Cloud Alliance
No full textThe paper presents the MicroElectronics Cloud Alliance (MECA) project which brings together eighteen partners from higher education institutions and enterprises to develop Cloud-based European infrastructure and organisation for education in micro- and nanoelectronics providing a range of open educational resources, remote access and sharing of educational and professional software, remote and practice-based learning facilities. Each university will provide remote access to its facilities, laboratory experiments or software systems for the partners in a cloud teaching system, giving them access to new resources. The common ones can be optimized, reducing the singular cost per institute and increasing the available computational and structural power
L'esperienza del dolore nei testi di Paolo Diacono: lo studio di un'emozione.
No full textLa presente tesi tratta del ruolo dell’esperienza dolorosa all’interno della vita e delle opere dell’autore longobardo Paolo Diacono (c.720 – c.799) e analizza, attraverso un'analisi linguistico-pragmatica e una riflessione ermeneutica, le diverse concettualizzazioni, modalità espressive e funzioni attribuite al dolore in relazione ai personaggi coinvolti sulla scena, agli scopi dell’autore e agli obbiettivi dei suoi committenti. L’elaborato si pone inoltre lo scopo di comprendere se Paolo Diacono comunicò e concettualizzò il dolore nello stesso modo per ogni sua opera, oppure se fece ricorso a espressioni e rappresentazioni specifiche rispondenti a diversi pubblici di riferimento. Infine, si intende indagare quale ruolo rivesta il dolore degli altri all’interno delle opere di Paolo, quali categorie di individui fossero riconosciute come degne di compassione e aiuto e, soprattutto, per quali motivi.This thesis examines the role of pain in the life and works of the Lombard author Paul the Deacon (c.720 - c.799). Through a linguistic, pragmatic, and hermeneutic analysis, it explores the different conceptualizations, modes of expression, and functions attributed to pain in relation to three factors: the characters involved in the scene, the author's aims, and the goals of his patrons. The research also attempts to understand whether Paul the Deacon used the same expressions and representations to communicate and conceptualize pain in his works, or if he tailored them to different target audiences. Additionally, the thesis investigates the role of the pain of others in Paul’s works, which categories of individuals he recognized as worthy of compassion and help, and why
When bio-Nanotechnology meets Microelectronics
No full textDuring the last years, material science was focusing on the exploration of the material characteristics at nanoscale. To completely exploit the ultra-small dimension and high sensitivity of these materials, researchers addressed the development of nanodevices including only a single nanostructured element, such as nanowires (NWs), nanotubes, molecules or nanoparticles. These nanomaterials can also be considered the basis for a new generation of bio-sensors able to interact with gas, molecules (e.g., DNA molecules) or other bio-substances at nanoscale. To electrically connect the nano-element, we use planar gold nanogaps (<10nm) organized in arrays and obtained through electromigration process controlled by a full custom PCB-based modular system. During first experiments, monolayers of conductive Thiophene molecules have been self-assembled onto the nanogap resulting in a gold-molecules-gold molecular junction. Even functionalized NWs can be placed in the nanogap using dielectrophoresis. The I/V characteristic of a Metal- Molecular-Metal junction shows that a plausible resistance is in the range 10MΩ – 10GΩ but it strongly depends on the size of NWs or on the type, the number and the length of bonded molecules on the nanogap. Basically, these new generation sensors rely on changes of electrical properties (R, C) of nanodevices that have to be converted into electrical signals with an ad-hoc interfacing circuit fabricated in a standard low-cost technology. The CMOS process satisfies these requirements. The design of the read-out circuit has to garantee: – large R and C read-out range, due to process variation of nanodevices; – high SNR, to measure ultra-low current flowing through molecular nanodevices; – low power consumption to support high densitity integration of nanosensors organized in array; A quasi-digital Resistance to time-domain converter (e.g., Resistance-to-Frequency(R2F), Resistance-to-Time(R2T), PWM) can be an adaptive and effective solution. The proposed R2F converter shows low measurement error (<1%) within the 50kΩ – 3GΩ range and consumes 142μW. Moreover, the last R2T prototype consumes only 8.5μW, it has higher linearity in the whole range with maximum measurement error of 0.8%
