Coworking in emergenza Covid-19: quali effetti per le aree periferiche?
No full textLa pandemia innescata dalla diffusione massiva del nuovo coronavirus SARS-CoV-2 ha presto alterato le
consuetudini e lo stile di vita di ciascun individuo in ogni parte del mondo (1). La forzata necessità di
alimentare il ‘distanziamento sociale’, al fine di ridurre al minimo le occasioni di contagio e di trasmissione
del virus, ha inevitabilmente sollevato l’esigenza di rimodulare anche le modalità di lavoro degli individui:
molti professionisti privati e dipendenti pubblici sono stati esortati a lavorare in smart working (lavoro agile).
Se, in molti casi, la dematerializzazione del luogo nell’ambito della prestazione di servizi può addirittura
significare lo snellimento di alcune prassi burocratiche (come alcuni servizi di base della PA), oltre che un
discreto time saving, per altre tipologie di lavoratori del terziario le misure di distanziamento sociale
possono produrre effetti decisamente negativi. È certamente il caso della classe di lavoratori creativi e
digitali, ad alta intensità di conoscenza e innovazione, molti dei quali sono utilizzatori abituali degli spazi di
coworking (CS) in qualità di coworkers (CW). Il coworking è definito dalla letteratura ‘third place’, ovvero una
alternativa al lavoro a domicilio (casa-first place) e al lavoro tradizionale in ufficio (second place), dove
lavoratori autonomi, liberi professionisti, start-up innovative e imprese possono interagire riducendo così i
rischi di isolamento e aumentando le occasioni di incontro e lo scambio di conoscenza ed esperienza, che
favorisce relazioni fiduciarie e di amicizia e nuove opportunità di business (Pais, 2012). L’interazione
dinamica e la prossimità fisica, sociale, cognitiva e organizzativa (a là Boschma, 2005) è l’essenza stessa dei
CS, dove l’interscambio è vitale per il funzionamento di tali moderne communities di lavoratori (Akhavan,
Mariotti, 2018; Mariotti, Akhavan, 2020). Inoltre, una parte significativa dei CS organizza eventi aperti alla
comunità e/o al pubblico che contribuiscono, a volte in modo significativo, ai ricavi del gestore

No full textAbstract
Today, we frequently observe social discriminations. These are tightly connected to stereotypes and intolerance toward others’ values differing to ours. Many of us do not have/take the chance to become aware of and question even our own values and ideologies behind them. Dialogue through a (foreign) language is considered as a ‘must’ toward social cohesion and mutual understanding (Council of Europe 2001). In much needed citizenship education, foreign language teachers can play a key role (Hosokawa, Otsuji, Mariotti 2016). This paper aims to demonstrate that ‘active learning’ language classes where learners are asked to think and choose the theme which each of them cares, whatever the themes and language proficiency levels are, can empower learners and teachers to became aware of their own values given they are guided to question the reasons behind their choices and to share their thoughts in meaningful dialogues (Hosokawa, 2019) between them and outside the classroom. This approach can move our classes toward more inclusive ones. The data to support the claim came from interviews, participant observation and submitted texts in three case studies: absolute- beginners (2016), undergraduate (2018), master (2019) Japanese language courses at an Italian university. The analysis focuses on a) interrelations between language proficiency and chosen themes; b) changing awareness toward own and others’ values; and c) relationship with peer-facilitators. The showcase will lead to No Level-Brick (NoLBrick) language education project, which suggests a de-standardized transformative-critical language education, where teachers and learners are seen as subjects of a reciprocally empowering citizenship formation process
Internationalisation : threat or opportunity for the survival of the Italian district model?
No full textNational borders in Europe have been opening since 1992 and the Union is expanding to embrace more countries prompting enterprises to consider alternative and more attractive locations outside their home country to handle part of their activities (Van Dijk and Pellenbarg, 2000; Cantwell and Iammarino, 2002). International relocation is becoming more and more popular even for small and medium-sized firms that are involved in a growing internationalisation process, mirroring the path of multinational enterprises. Italy, like other industrialised countries, is experiencing a fragmentation of the production chain: firms tend to shift high labour-intensive manufacturing activities to areas characterised by an abundance of low-cost labour (i.e. Central Eastern Europe, India, South East Asia, Latin America, Russia and Central Asia). The internationalisation process by Italian district SMEs has assumed significant dimensions. It has become a relevant topic in recent economic debate because of its consequences for the local context and, in particular, the implication for the survival of the Italian district model (see, among others, Becattini, 2002; Rullani, 1998 and Cor, 2000). The purpose of the paper is twofold: it aims at (i) identifying the managerial approaches to the internationalisation process adopted by the Italian district SMEs and by the Industrial District (ID) itself and (ii) at investigating whether the international delocalisation to the South Eastern European countries (SEECs) constitutes a threat or an opportunity for the Italian district model. The paper is organised as follows. The general introduction is followed by a description of the evolution of the internationalisation processes in Italy over the last three decades. Section three presents a discussion of the internationalisation strategies adopted by Italian SMEs. Section four focuses on the internationalisation process of the Italian industrial districts SMEs. A review of the studies on the subject is offered in section five. Section six presents a qualitative study on the internationalisation process as undergone by sports shoes manufacturers in the Montebelluna district, in north-east Italy. This study shows different managerial strategies to the internationalisation process and emphasises that the motivations can evolve over time, from originally cost-saving to increasingly market-oriented or global strategies. On the basis of a literature review, section seven investigates whether internationalisation constitutes a threat (i.e. loss of jobs and knowledge) or an opportunity (i.e. enlargement of the ID, update district s competitiveness) for the district model. Finally, some summarising remarks in section eight conclude the paper

Natural semidirect gauge mediation and D-branes at singularities
No full textWe consider semidirect gauge mediation models of supersymmetry breaking where the messengers are composite fields and their supersymmetric mass is naturally generated through quartic superpotential couplings. We show that such composite messenger models can be easily embedded in quiver gauge theories arising from D-branes at Calabi-Yau singularities, and argue that semidirect gauge mediation is in fact a very natural option for supersymmetry breaking in D-brane models. We provide several explicit examples and discuss their salient phenomenological properties. © 2009 The American Physical Society.http://arxiv.org/abs/0906.0727SCOPUS: ar.jinfo:eu-repo/semantics/publishe

NEURAL MODELLING OF FRICTION MATERIAL COLD PERFORMANCE
No full textThe complex and highly non-linear phenomena involved during braking are primarily caused by friction materials' characteristics. The final friction materials' characteristics are determined by their compositions, manufacturing, and the brake's operating conditions. Analytical models of friction materials' behaviour are difficult, even impossible, to obtain for the case of different brakes' operating conditions. That is why, in this paper, all relevant influences on the friction materials' cold performance have been integrated by means of artificial neural networks. The influences of 26 input parameters, defined by the friction materials' composition (18 ingredients), manufacturing (five parameters), and brake's operating conditions (three parameters), have been modelled versus changes of the brake factor C. Based on training and testing of 18 different architectures of neural networks with five learning algorithms, a total of 90 neural models have been investigated. The neural model (13112684 1) trained by the two-layered neural network, with a Bayesian regulation algorithm, was found to reach the best prediction results. This neural model was able to generalize the friction materials' cold performance, for temperatures in the contact of the friction pair T <= 100 C in the range of application pressure changes between 20 and 100 bar, and for initial speed changes between 20 and 100 km/h

It coordinates the efforts of the member institutes to offer all the potential users of interferometric facilities the best operational environment, providing software, academic formation and stimulating the prospective on new interferometric developments. At present, besides academic formation, the major effort isfocused on the development of the software to prepare the observations, to reduce the data and to interpret theresults in terms of models or reconstructed images. In this contribution, we describe the achievements and thefuture plans of the Mariotti Center
Are Coworkers in the Italian Peripheral Areas Performing Better? A Counterfactual Analysis
No full textCoworking spaces are “serendipity accelerators” designed to host creative people and entrepreneurs. While recent literature has started exploring the indirect effects of coworking spaces on the local context, little is still known on how coworking spaces may directly affect the coworkers’ economic performance and wellbeing. Using a novel dataset based on a survey of 326 CWs working in the Italian coworking spaces in 2018, this paper explores the potential economic impact for coworkers, depending on whether a coworking space is localized in a peripheral or an urban area. Through a propensity-score matching approach, we found that being located in a peripheral area for coworkers may represent an opportunity to earn more than working in an urban center. The same holds for the organization coworkers belong to
