This study enters the world of migrants women daily involved in the work of caregiving to elderly people in Modena. The multidimensional analysis that characterizes this work brings together elements which are examined, simultaneously, as bounds and/or opportunities within the migratory experience of these women. The interviews collected will be analyzed in parallel and linked to the international debates on contemporary migrations: the meaning of transnational migrations, the role of the networks in guiding integration, the limits and strengths of multiculturalist theories, the concept of ‘superdiversity’, the link among entitlement, rights and access to citizenship. The present study place at the centre of its observation the “daily practices” that allow every migrant to negotiate its ‘power’, its ‘freedom’ and its ‘rights’, so as to recognize agency to these women in the creation of their strategies and social boundaries. Moreover, the study focuses on the ability and power of the State, and its institutions, to create categorizations among migrants based on their social and economic ‘usefulness’, which produce effects in the daily lives of these workers.

The thesis has three chapters. The first one focuses in general on the associated employment, trying to give a unitary perspective and to show the several readings given by scholars. In detail, the thesis underlines the peculiar features of the associated employment relationships. The following chapters deal with the contract of associazione in partecipazione labour intensive. In the second chapter, this contract is analysed as it was originally provided by the Civil Code, with references to the relevant jurisprudence. In the third chapter, the thesis stresses the most outstanding characteristics of the contract in recent years, analysing all the legislative reforms in the field (in particular article 86, par. 2, Decree n. 276 of 2003 and its consequences in terms of social contribution), trying to interpret them in the present context.

A Machining Centre is nowadays a complex mechanical, electronic, electrical system that needs integrated design capabilities which very often require a high time-consuming effort. Numerical techniques for designing and dimensioning the machine structure and components usually requires different knowledge according to the system that have to be designed. This Ph. D Thesis is related about the efforts of the Authors to develop a system that allows to perform the complete project of a new machine optimized in its dynamic behaviour. An integration of the different systems developed, each of which respond to specific necessities of designer, is here presented. In particular a dynamic analysis system, based on a lumped mass approach, that rapidly allows to setup the drives of the machine and an Integrated Dynamic Simulation System, based on a FEM approach, that permit a dynamic optimization, are shown. A multilevel Data Base, and an operator interface module provide to complete the designing platform. The proposed approach represents a significant step toward the virtual machining for the prediction of the quality of the worked surface.

Il presente contributo prende le mosse dalla consapevolezza che i modelli lineari tradizionali sulle carriere (Super, 1980) hanno lasciato il passo a concettualizzazioni più complesse e non lineari (Cohen, Duberley & Mallon, 2004; Pryor & Bright, 2007; Richardson, 2002), argomento tra l’altro approfondito operando una disanima delle principali transizioni di carriera e dei fenomeni psicosociali ad esse correlate (Schlossberg, Waters & Goodman, 1995). Vengono affrontati temi attuali quali quelli della Globalizzazione riflessiva (Beck, 1999), della complessità e delle Flessibilità (Sennett, 1998) e se ne mette in luce le interrelazioni con il fenomeno delle carriere, ed in particolare delle dinamiche che ne hanno modificato progressivamente e radicalmente la natura nel corso degli ultimi trent’anni (Hall, 1976, 1996). È stato approfondito il tema dei nuovi percorsi di carriera, con particolare attenzione ai costrutti teorici della Protean Career (Carriera Versatile) e della Boundaryless Career (Carriera senza confini). Sono stati condotti due studi, mediante il metodo dell’inchiesta, proponendo dei questionari autosomministrabili a due gruppi di lavoratori dipendenti. La selezione degli strumenti da inserire nel protocollo, e quindi delle ipotesi da verificare è stata operata in funzione delle caratteristiche intrinseche dei due gruppi coinvolti, cercando comunque di valorizzare sempre il ruolo dei nuovi orientamenti di carriera all’interno del disegno di ricerca. Lo studio 1 è stato condotto su un gruppo di 540 lavoratori dipendenti provenienti da Sardegna e Sicilia. Facendo riferimento agli studi tradizionali sull’insicurezza lavorativa (Sverke & Hellgren, 2002), si è cercato di valutare l’eventuale effetto moderante dei nuovi orientamenti di carriera (Briscoe, Hall & Frautschy De Muth, 2006) circa gli effetti dell’insicurezza su benessere psicofisico (Goldberg, 1972) e coinvolgimento lavorativo (Schaufeli, Bakker & Salanova, 2006; Scaufeli, Salanova, Gonzalez-Romá & Bakker, 2002). I risultati hanno mostrato alcuni effetti parziali, ma d’altro canto è emerso che i medesimi orientamenti di carriera risultano significativamente e direttamente associati a variabili quali l’Autoefficacia, la Proattività, il benessere e il Coinvolgimento. Lo studio 2, riguardante un gruppo di 79 neolaureati di Palermo e provincia al primo inserimento lavorativo, è stato condotto nell’arco di 8 mesi con tre rilevazioni dati. In questo caso si è cercato di evidenziare eventuali effetti causali longitudinali degli orientamenti di carriera sulle variabili dipendenti già incluse nello studio 2. Le ipotesi espresse hanno trovato soltanto parziale conferma nei risultati.

Sociology of work in Italy revived at the end of WWII, after thirty years of forced oblivion. This thesis examines the history of discipline by considering three paths that it followed from its revival up to its institutionalization: the influence of the productivity drive, the role of trade unions and the activity of early young researchers. European Productivity Agency's Italian office Comitato Nazionale per la Produttività propagandised studies on management and on the effects of the industrialization on work and society. Academicians, technicians, psychologists who worked for CNP started rethinking sociology of work, but the managerial use of sociology was unacceptable for both trade unions and young researchers. So âfree unionâ CISL created a School in Florence with an eager attention to social sciences as a medium to become a new model union, while Marxist CGIL, despite its ideological aversion to sociology, finally accepted the social sciences lexicon in order to explain the work changes and to resist against the employers' association offensive. On the other hand, political and social engagement led a first generation of sociologists to study social phenomenon in the recently industrialized Italy by using the sociological analysis. Finally, the thesis investigate the cultural transfers from France, whose industrial sociology (sociologie du travail) was considered as a reference in continental Europe. Nearby the wide importance of French sociologie, financially aided by planning institutions in order to employ it in the industrial reconstruction, other minor experiences such as the social surveys accomplished by worker-priests in the suburbs of industrial cities and the heterodox Marxism of the review âSocialisme ou Barbarieâ influenced Italian sociology of work.

After having covered the international regulation in the labour market and in the control mechanisms fighting the irregular and the concealed labour, the Author concentrates on the Italian system’s answers to the requests coming from the European Union. Starting from the White Book on the labour market in Italy, the problems originated by the Legislative Decree 124/2004 and, moreover, those which have affected the fight against the concealed labour are dealt with. The aim study is to verify that the juridical regulation adopted by the national lawmaker has contributed to solve the problems connected to the labour flexibility and the consequent temporary employment. The analysis of the problems has led to the conclusion that, regardless the lawmaker’s good intentions, the basic principles of the national juridical system do not allow the achievement of a full realization of the objectives. This is mainly because the lack of effective systems to protect the flexible employees often treated as temporary employees, and because of the difficulties to introduce the legal culture on which the whole system should stand.
