La protezione dei diritti sociali nell'ordinamento dell'Unione Europea

This study deals with the protection of social rights in Europe and aims to outline the position currently held by these rights in the EU law. The first two chapters provide an overview of the regulatory framework in which the social rights lie, through the reorganisation of international sources. In particular the international instruments of protection of social rights are taken into account, both at the universal level, due to the activity of the United Nations Organisation and of its specialized agency, the International Labour Organization, and at a regional level, related to the activity of the Council of Europe. Finally an analysis of sources concludes with the reconstruction of the stages of the recognition of social rights in the EU. The second chapter describes the path followed by social rights in the EU: it examines the founding Treaties and subsequent amendments, the Charter of Fundamental Social Rights of Workers of 1989 and, in particularly, the Charter of Fundamental Rights of the European Union, the legal status of which was recently treated as the primary law by the Treaty of Lisbon signed in December 2007. The third chapter is, then, focused on the analysis of the substantive aspects of the recognition of the rights made by the EU: it provides a framework of the content and scope of the rights accepted in the Community law by the Charter of Fundamental Rights, which is an important contribution to the location of the social rights among the fundamental and indivisible rights of the person. In the last section of the work, attention is focused on the two profiles of effectiveness and justiciability of social rights, in order to understand the practical implications of the gradual creation of a system of protection of these rights at Community level. Under the first profile, the discussion is focused on the effectiveness in the general context of the mechanisms of implementation of the “second generation” rights, with particular attention to the new instruments and actors of social Europe and the effect of the procedures of soft law. Second part of chapter four, finally, deals with the judicial protection of rights in question. The limits of the jurisprudence of the European Union Court of Justice are more obvious exactly in the field of social rights, due to the gap between social rights and other fundamental rights. While, in fact, the Community Court ensures the maximum level of protection to human rights and fundamental freedoms, social rights are often degraded into mere aspirations of EU institutions and its Member States. That is, the sources in the social field (European Social Charter and Community Charter) represent only the base for interpretation and application of social provisions of secondary legislation, unlike the ECHR, which is considered by the Court part of Community law. Moreover, the Court of Justice is in the middle of the difficult comparison between social values and market rules, of which it considers the need to make a balance: despite hesitancy to recognise the juridical character of social rights, the need of protection of social interests has justified, indeed, certain restrictions to the free movement of goods, freedom to provide services or to Community competition law. The road towards the recognition and the full protection of social rights in the European Union law appears, however, still long and hard, as shown by the recent judgments Laval and Viking, in which the Community court, while enhancing the Nice Charter, has not given priority to fundamental social rights, giving them the role of limits (proportionate and justified) of economic freedoms.

Formazione, apprendimento e nuove prospettive e-learning. Lo sviluppo delle nuove tecnologie didattiche e la creazione di sistemi di apprendimento lungo l’intero arco della vita

The thesis of this paper is based on the assumption that the socio-economic system in which we are living is characterised by three great trends: growing attention to the promotion of human capital; extremely rapid technological progress, based above all on the information and communication technologies (ICT); the establishment of new production and organizational set-ups. These transformation processes pose a concrete challenge to the training sector, which is called to satisfy the demand for new skills that need to be developed and disseminated. Hence the growing interest that the various training sub-systems devote to the issues of lifelong learning and distance learning. In such a context, the so-called e-learning acquires a central role. The first chapter proposes a reference theoretical framework for the transformations that are shaping post-industrial society. It analyzes some key issues such as: how work is changing, the evolution of organizational set-ups and the introduction of learning organization, the advent of the knowledge society and of knowledge companies, the innovation of training processes, and the key role of ICT in the new training and learning systems. The second chapter focuses on the topic of e-learning as an effective training model in response to the need for constant learning that is emerging in the knowledge society. This chapter starts with a reflection on the importance of lifelong learning and introduces the key arguments of this thesis, i.e. distance learning (DL) and the didactic methodology called e-learning. It goes on with an analysis of the various theoretic and technical aspects of e-learning. In particular, it delves into the theme of e-learning as an integrated and constant training environment, characterized by customized programmes and collaborative learning, didactic assistance and constant monitoring of the results. Thus, all the aspects of e-learning are taken into exam: the actors and the new professionals, the virtual communities as learning subjects, the organization of contents in learning objects, the conformity to international standards, the integrated platforms and so on. The third chapter, which concludes the theoretic-interpretative part, starts with a short presentation of the state-of-the-art e-learning international market that aims to understand its peculiarities and its current trends. Finally, we focus on some important regulation aspects related to the strong impulse given by the European Commission first, and by the Italian governments secondly, to the development and diffusion of e-learning. The second part of the thesis (chapters 4, 5 and 6) focus on field research, which aims to define the Italian scenario for e-learning. In particular, we have examined some key topics such as: the challenges of training and the instruments to face such challenges; the new didactic methods and technologies for lifelong learning; the level of diffusion of e-learning in Italy; the relation between classroom training and online training; the main factors of success as well as the most critical aspects of the introduction of e-learning in the various learning environments. As far as the methodological aspects are concerned, we have favoured a qualitative and quantitative analysis. A background analysis has been done to collect the statistical data available on this topic, as well as the research previously carried out in this area. The main source of data is constituted by the results of the Observatory on e-learning of Aitech-Assinform, which covers the 2000s and four areas of implementation (firms, public administration, universities, school): the thesis has reviewed the results of the last three available surveys, offering a comparative interpretation of them. We have then carried out an in-depth empirical examination of two case studies, which have been selected by virtue of the excellence they have achieved and can therefore be considered advanced and emblematic experiences (a large firm and a Graduate School).

Business Clusters in Eastern Europe: Policy Analysis and Cluster Performance

Clusters have increasingly become an essential part of policy discourses at all levels, EU, national, regional, dealing with regional development, competitiveness, innovation, entrepreneurship, SMEs. These impressive efforts in promoting the concept of clusters on the policy-making arena have been accompanied by much less academic and scientific research work investigating the actual economic performance of firms in clusters, the design and execution of cluster policies and going beyond singular case studies to a more methodologically integrated and comparative approach to the study of clusters and their real-world impact. The theoretical background is far from being consolidated and there is a variety of methodologies and approaches for studying and interpreting this phenomenon while at the same time little comparability among studies on actual cluster performances. The conceptual framework of clustering suggests that they affect performance but theory makes little prediction as to the ultimate distribution of the value being created by clusters. This thesis takes the case of Eastern European countries for two reasons. One is that clusters, as coopetitive environments, are a new phenomenon as the previous centrally-based system did not allow for such types of firm organizations. The other is that, as new EU member states, they have been subject to the increased popularization of the cluster policy approach by the European Commission, especially in the framework of the National Reform Programmes related to the Lisbon objectives. The originality of the work lays in the fact that starting from an overview of theoretical contributions on clustering, it offers a comparative empirical study of clusters in transition countries. There have been very few examples in the literature that attempt to examine cluster performance in a comparative cross-country perspective. It adds to this an analysis of cluster policies and their implementation or lack of such as a way to analyse the way the cluster concept has been introduced to transition economies. Our findings show that the implementation of cluster policies does vary across countries with some countries which have embraced it more than others. The specific modes of implementation, however, are very similar, based mostly on soft measures such as funding for cluster initiatives, usually directed towards the creation of cluster management structures or cluster facilitators. They are essentially founded on a common assumption that the added values of clusters is in the creation of linkages among firms, human capital, skills and knowledge at the local level, most often perceived as the regional level. Often times geographical proximity is not a necessary element in the application process and cluster application are very similar to network membership. Cluster mapping is rarely a factor in the selection of cluster initiatives for funding and the relative question about critical mass and expected outcomes is not considered. In fact, monitoring and evaluation are not elements of the cluster policy cycle which have received a lot of attention. Bulgaria and the Czech Republic are the countries which have implemented cluster policies most decisively, Hungary and Poland have made significant efforts, while Slovakia and Romania have only sporadically and not systematically used cluster initiatives. When examining whether, in fact, firms located within regional clusters perform better and are more efficient than similar firms outside clusters, we do find positive results across countries and across sectors. The only country with negative impact from being located in a cluster is the Czech Republic.

Sviluppo di sperimentazioni per la produzione di getti in lega di alluminio a caratteristiche difettologiche e microstrutturali controllate, per la validazione di modelli di previsione delle porosità

Nei processi di progettazione e produzione tramite tecnologie di colata di componenti in alluminio ad elevate prestazioni, risulta fondamentale poter prevedere la presenza e la quantità di difetti correlabili a design non corretti e a determinate condizioni di processo. Fra le difettologie più comuni di un getto in alluminio, le porosità con dimensioni di decine o centinaia di m, note come microporosità, hanno un impatto estremamente negativo sulle caratteristiche meccaniche, sia statiche che a fatica. In questo lavoro, dopo un’adeguata analisi bibliografica, sono state progettate e messe a punto attrezzature e procedure sperimentali che permettessero la produzione di materiale a difettologia e microstruttura differenziata, a partire da condizioni di processo note ed accuratamente misurabili, che riproducessero la variabilità delle stesse nell’ambito della reale produzione di componenti fusi. Tutte le attività di progettazione delle sperimentazioni, sono state coadiuvate dall’ausilio di software di simulazione del processo fusorio che hanno a loro volta beneficiato di tarature e validazioni sperimentali ad hoc. L’apparato sperimentale ha dimostrato la propria efficacia nella produzione di materiale a microstruttura e difettologia differenziata, in maniera robusta e ripetibile. Utilizzando i risultati sperimentali ottenuti, si è svolta la validazione di un modello numerico di previsione delle porosità da ritiro e gas, ritenuto ad oggi allo stato dell’arte e già implementato in alcuni codici commerciali di simulazione del processo fusorio. I risultati numerici e sperimentali, una volta comparati, hanno evidenziato una buona accuratezza del modello numerico nella previsione delle difettologie sia in termini di ordini di grandezza che di gradienti della porosità nei getti realizzati.

Servizi relazionali e inclusione sociale: due studi di caso sul coinvolgimento delle famiglie nel Comune di Parma

La presente ricerca muove i suoi primi passi dall’ipotesi generale che il paradigma relazionale possa offrire al mondo dei servizi sociali una configurazione diversa, talora meno utopistica, del community work. Sebbene, infatti, in questi anni il sistema di offerta dei servizi si sia arricchito di principi come la co-progettazione e la co-responsabilità delle azioni, il lavoro di comunità resta ancora molto distante dal lavoro generalmente svolto nei servizi sociali territoriali, incapaci per ragioni strutturali e culturali di accogliere dentro di sé tale funzione. L’idea dalla quale trae origine la presente tesi di dottorato, è pertanto quella di arricchire la definizione di servizi sociali relazionali. Partendo dalle dimensioni che in letteratura sociologica e nei principali modelli teorici di social work definiscono un servizio alla persona quale servizio relazionale, nella prima parte teorica viene ipotizzata una trasformazione parziale del welfare regionale emiliano, poiché ai mutamenti culturali di questi anni non ha fatto seguito un cambiamento reale dei modelli operativi maggiormente basati sullo sviluppo delle competenze. Nella seconda parte della tesi, la ricerca empirica si focalizza sui progetti “family friendly” realizzati nel Comune di Parma, collocati in una logica di welfare societario e basati sull’apporto di soggetti di Terzo Settore, responsabili di ogni fase di realizzazione delle attività. La ricerca si avvale prevalentemente di tecniche qualitative e in alcuni tratti assume le caratteristiche della ricerca-azione. Nelle conclusioni, il contesto territoriale studiato rivela grande ricchezza dei legami strutturali, ma anche necessità di un rafforzamento dei legami interni. La forza dei servizi prodotti si situa, inoltre, nella sovrafunzionalità del legame tra volontari e famiglie, e di questo elemento dovrebbe arricchirsi anche il social work che scelga di adottare una prospettiva metodologica di lavoro relazionale.

Towards Centrifugal Compressor Stages Virtual Testing

Flow features inside centrifugal compressor stages are very complicated to simulate with numerical tools due to the highly complex geometry and varying gas conditions all across the machine. For this reason, a big effort is currently being made to increase the fidelity of the numerical models during the design and validation phases. Computational Fluid Dynamics (CFD) plays an increasing role in the assessment of the performance prediction of centrifugal compressor stages. Historically, CFD was considered reliable for performance prediction on a qualitatively level, whereas tests were necessary to predict compressors performance on a quantitatively basis. In fact "standard" CFD with only the flow-path and blades included into the computational domain is known to be weak in capturing efficiency level and operating range accurately due to the under-estimation of losses and the lack of secondary flows modeling. This research project aims to fill the gap in accuracy between "standard" CFD and tests data by including a high fidelity reproduction of the gas domain and the use of advanced numerical models and tools introduced in the author's OEM in-house CFD code. In other words, this thesis describes a methodology by which virtual tests can be conducted on single stages and multistage centrifugal compressors in a similar fashion to a typical rig test that guarantee end users to operate machines with a confidence level not achievable before. Furthermore, the new "high fidelity" approach allowed understanding flow phenomena not fully captured before, increasing aerodynamicists capability and confidence in designing high efficiency and high reliable centrifugal compressor stages.

Moduli consensuali nei rapporti tra Stato e autonomie territoriali e ruolo delle Conferenze

Ad oltre un decennio dalla riforma costituzionale del 2001, la non compiuta attuazione della stessa sembra condurre ad una nuova ed assai prossima revisione costituzionale. Nel mutato quadro costituzionale di quest’ultimo periodo l’attenzione e l’interesse sono stati richiamati da una grande quantità di accordi, di intese e di altri moduli consensuali, introdotti ed esitati nei rapporti tra Stato ed autonomie territoriali. Dall’esame del sistema delle Conferenze si è evidenziata la loro indispensabilità ai fini del coordinamento delle azioni politico –amministrative delle autonomie territoriali, ma è anche venuta fuori l’esigenza di ricorrere frequentemente ad altri tipi di moduli consensuali, spesso non tipizzati in ambito legislativo. I principi di sussidiarietà e di leale collaborazione inducono non di rado ad assumere, nella concretezza, forme eterogenee poco chiare e confuse (accordo, intesa, concerto, parere) che, pur considerati i contributi offerti dalla dottrina e dalla giurisprudenza, richiederebbero un intervento da parte del legislatore. L’approfondimento tematico ha rilevato, nel contesto di rapporti tra Stato ed autonomie territoriali, un movimento per così dire ondulatorio tra accese spinte autonomistiche e rimarcate esigenze centralistiche, lasciando ancora nella prospettiva una operativa ed efficiente armonia istituzionale.
