La criminalità organizzata ha aumentato la propria presenza nell’economia legale attraverso l’infiltrazione in aziende, generando così delle conseguenze negative per il sistema economico e alterando le relazioni tra attori economici. Molti paesi europei hanno adottato dei sistemi di recupero di capitali illeciti, ma l’Italia è la sola che prevede anche il recupero di aziende come misura di contrasto efficace. La politica di recupero dei capitali illeciti dovrebbe ridurre l’infiltrazione della criminalità organizzata nelle aziende, ma ad oggi è assente una valutazione la politica di recupero delle aziende infiltrate da gruppi criminali. Questa tesi intende valutare la politica di recupero delle aziende infiltrate dalla criminalità organizzata in Italia. L’analisi riguarda la valutazione dell’efficacia, efficienza e impatto di questa politica e, attraverso lo studio di nove casi, propone un nuovo quadro di analisi che combina diversi metodi (es. analisi degli indici di bilancio) e fonti (es. casi giudiziari e bilanci). Lo studio dei casi mostra che il recupero delle aziende è efficace se l’amministratore giudiziario ha esperienze manageriali; è efficiente se i procedimenti di recupero sono brevi e l’azienda viene destinata ad uso sociale; ed ha un impatto positivo se i media e le associazioni locali si interessano alle sorti dell’azienda. / By misusing legitimate businesses, organised crime is increasingly present in legal economies, generating serious consequences for legal systems and distorting relationships among legal actors. Several European countries have adopted asset-recovery regimes, but Italy is the only one that foresees the confiscation of companies as an effective countermeasure. Taking profits out of crime should curtail its infiltration into legitimate businesses, but there are no evaluations of the recovery of companies once infiltrated by organised crime. This study aims to evaluate the recovery of confiscated companies infiltrated by organised crime in Italy. It measures the effectiveness, efficiency and impact of this policy, and, analysing nine cases to assess the achievement of the policy objectives, proposes a new analytical framework that combines different methods (e.g. financial ratio analysis) and sources (e.g. judicial files and balance sheets) to evaluate asset-recovery policies. The results from case studies show that the recovery of companies is effective if the legal administrator has managerial skills; it is efficient if the proceedings are short and the company is disposed to social reuse; and it has a positive impact if media and local associations show an interest in the company.

This work has consisted in 1) determining, using finite elements method, the thermal and mechanical influence of the electronic base plate material; 2) elaborating (using hot pressing, spark plasma sintering and hot extrusion) aluminium/carbon fibres composites; and 3) linking the microstructures observed to the elaboration parameters and to the thermomechanical properties measured.

O objetivo desse trabalho foi desenvolver um compósito cerâmico de zircônia-grafeno para aplicação odontológica. Este estudo avaliou o efeito do pó de partida, concentração de grafeno e da temperatura de sinterização sobre as propriedades mecânicas (dureza e tenacidade à fratura) do compósito desenvolvido. Para isto foram sintetizados os pós de Y-TZP a partir de soluções de óxido-cloreto de zircônio e cloreto de ítrio na proporção desejada de 3mol% através da rota de co-precipitação em solução de hidróxido de amônio seguido por uma série de lavagens em água, etanol e butanol com posterior destilação azeotrópica, secagem, moagem e calcinação. O grafeno foi obtido a partir da exfoliação química de grafite pelo método de Hummers [40] modificado por Marcano [39], o que resultou em um gel acastanhado que foi submetido a lavagem por centrifugação, secagem e desaglomeração em almofariz de ágata, resultando, por fim, no óxido de grafeno. Uma segunda etapa foi o processo de redução química com ácido ascórbico para obtenção de óxido de grafeno reduzido, um pó de coloração escura que foi adicionado à Y-TZP para a obtenção do compósito nas diversas concentrações (em mol%) que foram estudadas: (0,01%, 0,05%, 0,10%, 0,50%, 1,00% e 2,00%). Os pós foram caracterizados por termogravimetria, difração de raios X e espectroscopia (FT-IR). Os espécimes foram confeccionados em matriz metálica cilíndrica e sinterizados em forno tubular em atmosfera inerte. Outros espécimes foram confeccionados em matriz de grafite de alta densidade e sinterizados por Spark Plasma Sintering (SPS). Todas as amostras foram caracterizadas por meio de ensaios de densidade, dureza Vickers, tenacidade à fratura e microscopia eletrônica de varredura. Os maiores valores de densidade relativa foram observados para as amostras sinterizadas em SPS, sendo que se obteve valor de densidade relativa de 98,7 % para a concentração de 0,50% de grafeno e 98,4% para a Y-TZP pura. Por outro lado, o maior valor encontrado em sinterização em atmosfera a 1400°C sem a presença de H2 para Y-TZP pura foi da ordem de 96,76%. Os valores de dureza foram maiores nas amostras sinterizadas em SPS, no entanto a tenacidade à fratura mostrou não se alterar em função do conteúdo de grafeno. As fotomicrografias de MEV mostraram que houve uma variação de tamanho de grão de acordo com a presença do grafeno e do método de sinterização. De acordo com os resultados obtidos neste trabalho foi possível concluir que o processamento desenvolvido permitiu a criação de um compósito cerâmico zircônia-grafeno que pôde ser caracterizado por diversos métodos analíticos. A densidade teórica do compósito desenvolvido não foi alcançada por meio de nenhum dos métodos de sinterização utilizados (Tubular ou SPS) e nem variando-se a temperatura. Para espécimes sinterizados em atmosfera inerte, a maior temperatura de sinterização (1400°C) e a presença do gás H2 não melhorou a densificação. Além disso, esses espécimes tiveram aumento da dureza com o aumento da concentração de grafeno, entretanto, a sua tenacidade à fratura não foi afetada pelo teor de grafeno. Para espécimes sinterizados por meio de SPS, a temperatura de sinterização de 1350°C resultou em melhores valores de densificação. Além disso, para este tipo de sinterização, tanto a dureza como a tenacidade à fratura foram afetadas pelo teor de grafeno. / The objective of this work was to develop a zirconia-graphene ceramic composite for dental application. The study evaluated the effect of the starting powder effect, graphene concentration and sintering temperature on the mechanical properties of the composite. For this, the Y-TZP powders were synthesized from zirconium chloride and yttrium chloride solutions in the desired ratio of 3 mol% through the co-precipitation route in ammonium hydroxide solution followed by a series of washes in water, ethanol and butanol with subsequent azeotropic distillation, drying, grinding and calcination. Graphene was obtained from the chemical exfoliation of graphite by the method of Humans modified by Marcano, which resulted in a brownish gel that was subjected to washing by centrifugation, drying and deagglomeration in agate mortar, resulting finally in the graphene oxide. A second step was the chemical reduction with ascorbic acid to obtain reduced graphene oxide, a dark-colored powder that was added to the Y-TZP to obtain the composite in the various concentrations (in mol%) that were studied (0, 01%, 0.05%, 0.10%, 0.50%, 1.00% and 2.00%). The powders were characterized by thermogravimetry, X-ray diffraction and spectroscopy (FT-IR). The specimens were made in cylindrical metallic matrix and sintered in a tubular oven. Other samples were made in high density graphite matrix and sintered by Spark Plasma Sintering (SPS). All samples were characterized by means of density tests, Vickers hardness, fracture toughness and scanning electron microscopy. The highest values of relative density were observed for the sintered samples in SPS. A relative density of 98.7% was obtained for the 0.50% concentration of graphene and 98.4% for the pure Y-TZP. On the other hand, the highest value found in tubular sintering at 1400 ° C without the presence of H2 for pure Y-TZP was of the order of 96.76%. The hardness values were higher in the sintered samples in SPS, however the fracture toughness showed not to change as a function of the content of graphene. SEM images showed that there was a variation of grain size according to the presence of graphene and the sintering method. According to the results of this study it was concluded that the process developed allowed the creation of a graphene-zirconia ceramic composite which can be characterized by various analytical methods. The theoretical density of the composite developed was not achieved by any of the sintering methods used (tubular or SPS) nor by varying the temperature. For tubular sintered specimens, the higher sintering temperature (1400 ° C) and the presence of H2 gas did not improve densification. In addition, these specimens had increased hardness with increasing graphene concentration, however, their fracture toughness was not affected by graphene content. For sintered specimens by SPS, the sintering temperature of 1350 ° C resulted in better densification values. In addition, for this type of sintering, both hardness and fracture toughness were affected by the content of graphene

Comprendre les mécanismes de spéciation des Produits de Fission (PF) dans le combustible nucléaire est un enjeu majeur pour pouvoir estimer précisément le terme source d’un accident grave. Parmi les nombreux PF créés, certains sont très réactifs et peuvent avoir un impact radiologique important en cas de relâchement dans l’atmosphère. C’est notamment le cas du césium (Cs), du molybdène (Mo) et du baryum (Ba). C’est dans ce contexte que s’inscrit le travail de thèse qui propose d’apporter des données expérimentales sur l’effet du potentiel oxygène sur la spéciation du Cs, du Mo et du Ba dans des combustibles nucléaires, à différents stades d’un accident grave.Une approche thermodynamique a été utilisée en support à l’interprétation des données expérimentales obtenues dans le cadre de ce travail. Deux types d’échantillons ont été étudiés: des combustibles MOX irradiés et des matériaux simulant un combustible UO2 à fort taux de combustion, obtenus par frittage à haute température (SIMFuel). Les échantillons ont été traités thermiquement dans des conditions représentatives d’un accident grave survenant dans un Réacteur à Eau Pressurisée (REP). Les conditions expérimentales ont couvert une gamme de température allant de 400°C à 2530°C et des potentiels oxygène situés entre -470 kJ.mol(O2)-1 et -100 kJ.mol(O2)-1. Les échantillons ont été caractérisés finement avant et après chaque traitement à l’aide de techniques complémentaires comme la microscopie optique et électronique, la microsonde et le SIMS dans le cas de l’irradié. Des mesures de XANES sur synchrotron ont été réalisées sur SIMFuel et ont conduit à des résultats importants en termes de spéciation des PF. Enfin, la technique de Spark Plasma Sintering (SPS) a été explorée avec succès pour la fabrication de SIMFuel contenant du Cs, du Mo et du Ba sous des formes chimiques représentatives d’un combustible REP en fonctionnement nominal.Ce travail a permis de mettre en évidence l’effet de la température en conditions oxydantes sur le comportement du combustible et des PF. Une oxydation du Mo, initialement présent sous forme métallique dans les inclusions blanches du combustible, en MoO2 a été observée dès 1000°C en conditions oxydantes. Une interaction entre le MoO2 formé et le Ba contenu dans la phase oxyde a eu lieu dans les mêmes conditions, menant à la formation de BaMoO4. Le potentiel oxygène joue aussi un rôle important dans le phénomène d’interaction pastille-gaine, en favorisant la diffusion des espèces en conditions oxydantes, diminuant ainsi la température de fusion du combustible. / In the nuclear community, it is a top priority to gain in-depth understanding of fission product (FP) speciation mechanisms occurring in nuclear fuel in order to precisely estimate the source term of a severe accident. Among the FP produced, some are highly reactive and may have a strong radiological impact if released into the environment. This is particularly the case of cesium (Cs), molybdenum (Mo) and barium (Ba). In this context, the objective of this study is to provide experimental data on the effect of the oxygen potential on Cs, Mo and Ba speciation in nuclear fuels at different stages of a severe accident.A thermodynamic approach was coupled with the experimental work to support the interpretation of experimental data. Two types of samples were studied in detail: irradiated MOX fuels and simulated high burn-up UO2 fuels produced through sintering at high temperature (SIMFuel). The samples were submitted to thermal treatments in conditions representative of a pressurised water reactor (PWR) severe accident. This approach made it possible to cover a temperature range from 400°C up to 2530°C and oxygen potentials from -470 kJ.mol(O2)-1 to -100 kJ.mol(O2)-1. The samples were characterized before and after each test using complementary techniques like OM, SEM, EPMA and SIMS in the case of irradiated fuels. XANES measurements using synchrotron radiation facilities were performed on SIMFuels and provided valuable results on FP speciation. Moreover, spark plasma sintering (SPS) was successfully investigated for the production of SIMFuel samples containing Cs, Mo and Ba in a chemical state representative of PWR fuel in normal operating conditions.This work highlighted the effect of oxidizing severe accident conditions on the fuel and FP behavior. Oxidation of Mo initially contained in the fuel’s metallic inclusions into MoO2 was observed to take place around 1000°C in oxidizing conditions. An interaction between MoO2 and the oxide phase containing Ba took place in the same conditions, leading to the formation of BaMoO4. The oxygen potential also plays an important role in fuel-cladding interactions, enhancing the diffusion of species in oxidizing conditions and lowering the temperature at which fuel melting occurs.

L'élaboration de céramiques polycristallines transparentes constitue un défi technologique important. Les matériaux transparents actuellement utilisés (verres ou monocristaux) possèdent des propriétés mécaniques (dureté, résistance à l'usure) et physico-chimiques (résistance à la corrosion) moins intéressantes que celles des céramiques polycristallines. Par ailleurs, le coût de production de ces dernières est inférieur à celui des monocristaux. Les deux principaux paramètres à contrôler afin d'augmenter les propriétés optiques de l'alumine alpha polycristalline sont sa porosité, comme pour tout matériau transparent, et sa taille de grains, du fait de sa biréfringence. Aussi on cherchera à obtenir après frittage un matériau possédant une très faible porosité (inférieure à 0,05%) avec une distribution fine en taille de pores centrée sur des porosités nanométriques, et une taille de grains très fine (plus grand que 0,5 µm). Actuellement, cette microstructure particulière est obtenue en ~ 15 heures en combinant un frittage naturel suivi d'un traitement par Hot Isostatic Pressing (HIP). La technique de Spark Plasma Sintering (SPS) utilisée dans cette étude permet d’obtenir des céramiques denses possédant une microstructure fine en des temps plus courts. Premièrement, un protocole d'élaboration d'une alumine pure transparente a été mis au point. Il repose sur la préparation de crus à microstructure contrôlée avant l'étape de frittage. Principalement, ils doivent présenter une distribution fine en taille de pores avec un empilement particulaire macroscopique homogène dépourvu d'agglomérats. Le cycle de frittage SPS a également été optimisé afin d'obtenir les meilleures transmissions optiques possibles. Ensuite, un protocole de dopage par des inhibiteurs de croissance de grains a été optimisé. La nature du sel dopant influe au second ordre sur les propriétés optiques des échantillons par rapport à une calcination préalable au frittage. La nature et/ou la quantité de dopant induisent un décalage plus ou moins important de la densification vers les hautes températures. Le cycle de frittage SPS doit donc être adapté en conséquence. Le taux de dopant doit être optimisé afin d'obtenir une microstructure fine après frittage sans présence de particules de seconde phase. Différents dopants ont été comparés (magnésium Mg, lanthane La et zirconium Zr) et l'échantillon possédant les meilleures propriétés optiques a été obtenu grâce à un dopage à 200 cat ppm de lanthane. Des optimisations au niveau de la morphologie des poudres (plus fines et plus sphériques) et de la préparation des suspensions d'alumine alpha dopées au lanthane (lavage par centrifugation) ont permis d'obtenir l'un des meilleurs échantillons d'alumine transparente reporté dans la littérature. Il possède une transmission optique de 68% et une taille de grains de l'ordre de 300 nm. Ses propriétés mécaniques (dureté, résistance à l'abrasion) sont supérieures à celles d'un monocristal de saphir. / Obtaining transparent polycrystalline ceramics became an important technological challenge over the last decade. Their high mechanical (hardness, wear resistance) and physico-chemical (corrosion resistance) properties combined with a high transparency and a reasonable price could lead them to replace glasses or monocrystals as sapphire in optical applications. The main parameters to control in order to obtain highly transparent polycrystalline alpha-alumina (PCA) are the porosity size and amount as for the other transparent materials. However, as PCA is a birefringent material, the grain size also needs to be controlled. That’s why PCA should possess after sintering grains as small as possible (bigger than 0.5 µm) and a porosity closed to 0.00% with nanometric pores. This particular microstructure is usually obtained in ~ 15 hours by combining natural sintering in air with a post Hot Isostatic Pressing (HIP) treatment. In our study, the Spark Plasma Sintering (SPS) technique was used as it enables to obtain fully dense ceramics in shorter times while limiting the grain growth. First, a protocol to obtain a pure transparent PCA was established. It consists on preparing green bodies with a controlled particle’s packing before sintering. Mainly, the particle’s packing has to be macroscopically homogeneous and without agglomerates. Moreover, the pore size distribution should be the narrowest. The SPS sintering cycle was also optimised to obtain the highest optical transmission. Then, a doping protocol with grain growth inhibitors was optimised. The nature of the doping salt has a secondary effect on optical properties compared to a thermal treatment applied before sintering. Depending on the doping agent nature and/or amount, the densification temperature changes. The SPS sintering cycle has thus to be adapted. The doping agent amount has to be optimised to obtain a fine microstructure after sintering without second phase particles. Different doping agents have been compared (magnesium Mg, lanthanum La and zirconium Zr). The sample having the highest optical properties was doped with 200 cat ppm of lanthanum. Finally, an optimisation of the powder’s morphology (finer and more spherical) was performed. Moreover, the lanthanum doped alpha-alumina slurry’s preparation was optimized using centrifugation. All these processes have enabled us to obtain one of the most transparent PCA sample ever reported in the literature. It possesses an optical transmission of 68% and a grain size around 300 nm. Its mechanical properties (hardness, wear resistance) are higher than the ones of a sapphire monocrystal.

La ricerca si pone l’obiettivo di analizzare i servizi consultoriali rivolti alle famiglie/donne migranti nell’ambito delle politiche sociali che rivolgono un’attenzione specifica ai soggetti e alle famiglie della migrazione, osservandoli dal punto di vista del modello relazionale di buone pratiche (Donati P., Prandini R., 2006; Rossi G., Boccacin L., 2007), nell’ambito del Comune di Milano. Sono stati selezionati cinque consultori familiari significativi per il tipo di lavoro realizzato le famiglie immigrate, all’interno dei quali sono stati realizzati gli studi di caso. Gli obiettivi della ricerca sono: • Tracciare un profilo del campione d’ utenza immigrata che accede ai consultori familiari studiati (attraverso la rilevazione quantitativa). • Analizzare le pratiche di lavoro con le donne/famiglie immigrate. In particolare, valutare quanto le pratiche realizzate rispondono ad un modello di progettazione e di attuazione di tipo relazionale, quale posto sia riservato alla famiglia, a quale modello di integrazione si ispira e quale effetto abbia in termini di capitale sociale prodotto (attraverso la rilevazione qualitativa). E’ stata formulata una ipotesi generale, che si declina in tre ipotesi specifiche. Il Consultorio Familiare si configura come un servizio alla persona: 1. quando raggiunge un obiettivo di integrazione delle differenze culturali rispondendo ai bisogni degli utenti immigrati attraverso servizi che riconoscono e promuovono le appartenenze etniche (ad es. i gruppi di accompagnamento alla nascita ai quali partecipano donne di diversa appartenenza etnico - culturale), 2. quando riconosce e si prende cura dei legami familiari dell’utente immigrato (ad esempio estendendo la consultazione a più membri della famiglia), 3. quando realizza un modello relazionale di buone pratiche in quanto genera capitale sociale attraverso l’intreccio di 4 componenti: Efficienza, Efficacia, Integrazione del servizio in una rete di attori, La qualità etica dei fini perseguiti: benessere, protagonismo, empowerment e integrazione della famiglia migrante. L’approccio è multimedodologico per la scelta di più campioni (26 operatori, 4 coordinatori, 120 utenti), per l’utilizzo congiunto di più strumenti, (questionario e intervista) e infine, per quanto concerne l’uso di più metodi di analisi dei dati (quantitativo e qualitativo). In base alla prima ipotesi, il consultorio è un servizio alla persona nella misura in cui è capace di rispondere, con modelli di lavoro differenti, alla specificità della domanda dell’utenza, pur all’interno di un orientamento verso l’assimilazione dell’utenza che spinge verso il livellamento non solo della risposta del servizio, ma anche della domanda dell’utente. In base alla seconda ipotesi, il consultorio famigliare si configura come un servizio, che pur dichiarando un approccio alla famiglia nella mission perseguita, rivolge il proprio intervento al singolo utente o al massimo a diadi familiari. In base alla terza ipotesi, è stato possibile confermare la presenza di singole pratiche di lavoro attivate dagli operatori che rispondono ad un modello relazionale di buone pratiche, in quanto supportando la nascita di nuovi legami sociali e il confronto culturale, generano capitale sociale e promuovono l’integrazione. Dalla ricerca è emerso un quadro composito del complesso rapporto tra servizio consultoriale e utenza immigrata, che necessita di ulteriori approfondimenti di ricerca. / Research object is inquiring consultorio familiare within the frame of social policy. Consultorio familiare will be analysed to the point of good/best practices relational model (Donati P., Prandini R., 2006; Rossi G. , Boccacin L.,2007), in Milan, a city that has high level of immigrants clients. The research intends to define more precisely what kind of ‘good practices’ are realized, especially with regards to the immigrant families. The research aims : • To describe sample of immigrant clients who access to Consultorio familiare through quantitative research method • to shed light on family services related to immigrant families clients, in order to discover how the good practices and the social capital generate, level of family approach, model of integration realized with immigrant families. The observation of family services that are offered in Consultorio familiare, and the analysis of the social capital generation process, has been carried out through the realisation of 5 case studies identified among some experiences qualified as ‘good practices’. Specific hypothesis: Consultorio familiare is “servizio alla persona”: • When it reaches a goal of integration of cultural differences in response to immigrant clients' needs through services that recognize and promote the ethnic membership (eg. Birth groups for women of different ethnic-cultural membership), • when it recognizes and takes care of the immigrant's family ties (eg by extending the consultation to more family members) • When it achieves a relational model of good practice and generates social capital through the intertwining of 4 components: Efficiency, Effectiveness, Integration of service into a network of actors, the ethical quality of the purposes: wellbeing, protagonists, empowerment and integration of the family migrant. For the choice of different samples (providers and clients), as well as for the use of different, (questionnaire and interview) tools, and different (quantitative and qualitative) methods of data analysis, this research is based on a multi-methodological approach. Under the first hypothesis, Consultorio familiare is “servizio alla persona” to the extent is able to respond with different patterns of work to the specific nature of the requests, but in a shift towards user assimilation that leads to the same level of the provider response and the clients demand. Under the second hypothesis, Consultorio familiare is configured as a service, while stating that a family approach is pursued in the mission, it realizes a practice at an individualist or dyadic level, with one client or a maximum of family dyads. With the third hypothesis, it was possible to confirm the presence of specific working practices enabled by the providers responding to a relational model of good practice, supporting the emergence of new social ties and cultural confrontation, generate social capital and promote social integration. The research has shown a mixed picture of the complex relationship between immigrant clients and consultorio familiare, who needs further research investigations.

La presente tesi propone uno studio sulla multivittimizzazione delle banche in Italia. In questo paese nell’ultimo decennio si è concentrato circa il 50% delle rapine europee, delineando una situazione critica in termini di sicurezza e di impatto economico sulle banche. La ricerca empirica prova che il crimine si concentra su di una esigua parte della popolazione e che la vittimizzazione è il più efficace predittore di criminalità: dato un primo episodio, un target tende a subire un altro reato in un breve periodo di tempo. Mentre altre tipologie di reato sono state largamente esplorate, poco è stato fatto riguardo le rapine in banca. Questa tesi vuole colmare questa lacuna analizzando l’universo delle rapine in banca avvenute in Italia tra il 2007 ed il 2009. L’analisi dimostra che in Italia il 5% delle filiali concentra su di sé circa il 45% delle rapine; una volta vittimizzata, infatti, una banca viene esposta al 36% di probabilità di subire un’ulteriore rapina nei sei mesi successivi. Questa concentrazione è determinata dal successo della precedente rapina, che spinge gli stessi rapinatori a tornare(boost effect), ma anche dalle caratteristiche della banca (flag effect), che la espongono all’azione di più criminali. / The present thesis proposes a study on repeated bank robbery in Italy. In the last decade, about 50% of European bank robberies have occurred in this country, drawing a problematic situation in terms of both safety and economic impact on banks. Empirical research proves that crime is concentrated on a small proportion of the population and therefore victimization is the best predictor of crime. While repeat victimization has been studies with regard to several crime types, little attention has been paid to bank robbery. This thesis aims at filling this gap by analyzing the universe of bank robberies occurred in Italy between 2007 and 2009. The study shows that, in Italy, only 5% branches accounts for about 45% of all robberies; once victimized, indeed, a bank is exposed to 36% probabilities to be victimized again within the following six months. This concentration is determined by both the success of prior offence, which drives the repeats by original offenders (boost effect), and the characteristics of banks, which expose them to the action of multiple offenders (flag effect).

Il lavoro di tesi ha come oggetto la valutazione della qualità relazionale dei servizi offerti dal Centro disabilità neuromotorie infantili della Fondazione Ariel e ha come obiettivi l’approfondimento teorico e metodologico dell’approccio relazionale riflessivo alla valutazione, con attenzione alle connessioni tra valutazione e dimensioni organizzative dei servizi alla persona e alla famiglia. Questo approccio multidimensionale e multivision della qualità fa riferimento ad alcune macro-dimensioni organizzative del benessere relazionale generato da un servizio sociale: l’efficienza, l’efficacia, la qualità integrativa, la qualità etica dei fini. Questa prospettiva riflessiva e partecipata di valutazione costituisce un’opportunità per cogliere, descrivere e giudicare il bene comune relazionale generato da un servizio alla persona e alla famiglia in un contesto di bisogni sociali in mutamento, dove strategiche sono personalizzazione e alla familiarizzazione dei servizi. Oltre al potenziale conoscitivo, la valutazione della qualità relazionale dedica particolare attenzione al potenziale trasformativo e morfogenetico della leva valutativa. Metodologicamente l’analisi condotta è stata di tipo quanto-qualitativo. Sono state realizzate interviste semi-strutturate con gli operatori del Centro e una dettagliata analisi della documentazione. Il lavoro partecipato ha condotto alla costruzione di questionario di 35 variabili che è stato esitato da 167 famiglie beneficiarie. Oltre ad un’analisi monovariata dei risultati del questionario sono stati costruiti alcuni indici sintetici su alcune dimensioni critiche della qualità relazionale. / The work relates to evaluation of relational quality of the services offered by Foundation Ariel’s childhood neuromotor disabilities Center . The objectives are the methodological and theoretical study of the relational reflexive evaluation approach, with attention to the connections between evaluation and organizational dimensions services to individuals and families. This multidimensional and multi-vision quality model refers to some macro-organizational dimensions of relational well-being generated by social services: efficiency, effectiveness, quality integration, the quality of ethical purposes. This reflective and participatory evaluation perspective is an opportunity to capture, describe and assess the common good relationship generated by a service to individuals and families, which are strategic to the familiarization and customization in a context of changing social needs. In addition, relational quality evaluation pays particular attention to the transformative and morphogenetic potential of evaluation. Methodologically, the analysis was quanto-qualitative. Semi-structured interviews were conducted with operators of the Centre and a detailed analysis of the documentation was done. The work led to the construction of a questionnaire of 35 variables, which 167 beneficiary families have responded to. Besides monovariata analysis of the results of the questionnaire, some synthetic indexes of some critical dimensions of relational quality were constructed.

Negli ultimi decenni, l’affermazione del paradigma della società della conoscenza e le recenti politiche di sostegno all’apprendimento lungo tutto l’arco della vita, hanno evidenziato la questione dello skillmismatching tra competenze formate e fabbisogni professionali espressi dal mercato del lavoro. La finalità della ricerca è stata quella di ricostruire il frame culturale, valoriale e normativo entro cui si colloca l’emergenza del fabbisogno formativo dei lavoratori e di tracciare il percorso storico-evolutivo dell’analisi dei fabbisogni formativi (aff) come strumento, come costrutto e come pratica. L’indagine empirica, di tipo qualitativo, ha coinvolto i vari stakeholders che concorrono a definire, direttamente e indirettamente, la dinamica della domanda/offerta di formazione continua e delle politiche formative a sostegno dell’occupazione. Oltre alla ricerca sul campo, il lavoro di ricerca ha prodotto una mappa delle pratiche di analisi dei fabbisogni formativi condotte nell’ultimo decennio (nazionali ed internazionali), una rassegna metodologica delle tecniche di analisi dei fabbisogni formativi e quattro studi di caso sulle pratiche di analisi dei fabbisogni formativi come strumento di policy (Stati Uniti, Canada, Europa, Italia). / In recent decades the success of the paradigm of the knowledge society and the recent policies of support for lifelong learning highlighted the question of skillmismatching between skills and vocational needs expressed by the labor market and also the value of human capital for competitive advantage of the whole society. The aims of the research was to reconstruct the frame of culture, values and normative into which fits the emergency of training trying to trace the historical-evolutionary of training needs analysis (Tna) as a tool, as a constructs and as a practice. The empirical research was qualitative and considered various stakeholders wich to help define, directly and indirectly, the dynamics of supply/demand of continuing training of workers and training policies to support employment. The research has produced a map of the practices of training needs analysis carried out in the last decade (at national and international level), a methodological review of techniques of Tna and four case studies on international practices of training needs analysis Key-words: capability - skillmismatch – human capital - lifelong learning -multistakeholders - human resource – labour union – practices – continuing training of workers – social partners
