The Xiphoteuthididae Bather, 1892 (Aulacocerida, Coleoidea): an outline classification.
No full textProblems in the classification of the Xiphoteuthididae have been recently addressed (Mariotti and Pignatti, 1992, 1994, 1996; Pignatti and Mariotti, 1996), but a critical revision is still lacking, owing mainly to their incomplete fossil record. The following outline of a classification summarizes diagnostic characters, taxonomie relationships, and geological occurrences of the genera currently included in the family Xiphoteuthididae: Atractites Gumbel, 1861, Breviatractites Mariotti and Pignatti, 1992, Claviatractites Mariotti and Pignatti, 1996, Crassiatractites Mariotti and Pignatti, 1992, Delphinoteuthis Mariotti and Pignatti, 1994, Metabelemnites Flower, 1944, Choanoteuthis Fischer, 1951, and Calliconites Gemmellaro, 1904. The taxonomic status of Choanoteuthis and the suprageneric attribution of Calliconites remain uncertain
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

The location factors of the Italian transport and logistics investments in the European countries
No full textItaly is known as a “multinational follower” because of its lower rate of outward direct investments compared to the other industrialized countries. In fact, in 2006 the percentage ratio between the outward Foreign Direct Investments (FDI) and the GDP is about 20% (UNCTAD, 2007), the half of the European Union average value and strongly lower than the main ratio of the closest partners (i.e. Germany with a rate of 34.5% and France with 48.3%). Nevertheless, in the last decades the investments of the Italian transport and logistics firms have grown very quickly. According to Mariotti and Mutinelli (2009), since 2000 to 2006, the so-called pre-crisis period, the number of employees in the foreign affiliates of the logistics Italian MNE increased of 64.3%, while in the same period the investments undertaken by the Italian manufacturing MNE decreased.
The main destination areas of Italian outward transport and logistics FDI tend to be the European countries, especially West Europe (45% in 2010), while Central East Europe accounts for the 16% (in 2010) of total FDI (Maggi and Mariotti, 2011). West European countries are, indeed, the main destination of Italian export, while the Centre-Eastern countries especially in the ‘80s and ‘90s have attracted several manufacturing delocalisation projects (Mariotti, Piscitello, 1995; Venables, 1999; Baldone at al., 2002; Mariotti and Montagnana, 2008; Elia et al., 2011). This trend seems confirm that the logistics industry is strongly demand-driven: the transport and logistics providers follow their customers in the internationalisation processes (market-seeking investments) (Maggi, Mariotti, 2010).
The present paper starts from this assumption and aims at identifying the main determinants of the Italian FDI in transport and logistics towards the European Countries (Guimarães et al., 2007; Hong, 2007 a,b).
In order to do that, an econometric analysis is developed, where the dependent variable is the number of outward FDI undertaken by the Italian transport and logistics MNE in Europe (data come from the LogINT - Logistics and Internationalisation- database, Politecnico di Milano).
The paper is structured into five sections. The introduction is followed by a literature review on the FDI determinants, and specifically, on those belonging to the transport and logistics industry. Section three is dedicated to data and methodology. Descriptive statistics and the results of the econometric estimation are described and discussed in section four. Section five concludes the paper

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

Villa Micheli - Mariotti
No full textIl percorso di indagine sulla Villa Micheli-Mariotti, collocata a Monticelli Terme, è stato condotto primariamente nell’ambito di una attività scientifica universitaria; alcuni focus sono stati approfonditi attraverso la feconda esperienza di tesi di laurea, mentre alcuni studi tematici hanno richiesto apporti specifici di collaborazione; l’analisi si è ulteriormente arricchita e sostanziata nell’ambito delle attività di un Dottorato di Ricerca.
Questa sinergia ha consentito di ottenere un prodotto editoriale articolato, caratterizzato da un percorso lineare chiaro, convincente e dotato di un ricco apparato grafico e fotografico, che attraversa le molteplici declinazioni di analisi di un edificio: dalla ricerca dei documenti storico-iconografici disponibili, utili a testimoniare le diverse fasi di trasformazione del manufatto, all’imprescindibile analisi fotografica, ai rilievi diretto e indiretto per approdare ai necessari approfondimenti diagnostici attraverso le endoscopie e le termografie, per la valutazione del degrado delle strutture.
Un rilievo integrato, dunque, le cui responsabili scientifiche non si sono accontentate dei risultati conoscitivi raggiunti riguardanti l’immagine della fabbrica architettonica, ma hanno scelto di metterli a sistema ricorrendo al modello digitale parametrico BIM. Questa scelta è stata perseguita allo scopo di garantire ai proprietari una più agevole e accorta manutenzione del bene, che comporta un impegno gravoso non solo dal punto di vista economico ma anche della sua ordinaria gestione
