La ricerca rappresenta un'indagine qualitativa di carattere esplorativo in merito al tema dell’identità e delle rappresentazioni sociali dei bambini che vivono sulle strade di Nairobi (Kenya). Sono state messe in luce e analizzate le numerose rappresentazioni degli street children, tra cui quella spregiativa – chokora – elaborata dalla comunità locale, che li assimila a rifiuti) per far emergere quanto l’identità del bambino di strada possa essere compresa facendo riferimento al soggetto come a un prodotto di condizionamenti sociali e culturali o anche come entità potenzialmente capace, all’interno di una continuità narrativa, di elaborare riflessivamente la propria esperienza e di produrre attivamente nuovi significati e nuove forme sociali. Sotto il profilo metodologico sono state realizzate quarantanove interviste strutturate, dodici semistrutturate e sessantacinque in profondità a street dwellers, ex street boys, famigliari di street children, operatori di ONG e CBO, testimoni privilegiati e soggetti della comunità locale. Si è fatto inoltre uso della tecnica visuale del diario fotografico e dell’osservazione partecipante. La ricerca empirica ha messo in luce che l’identità degli street children si struttura su relazioni di appartenenza e di differenziazione. Le rappresentazioni sociali sono determinanti per il processo identitario degli street children, ma è possibile un margine di negoziazione della propria identità, alla luce della conversazione interiore, che consente una ristrutturazione attorno a un perno positivo del sé relazionale. Questo avviene quando la negoziazione dell’identità viene vissuta come un processo relazionale, guidato dalle premure fondamentali del soggetto e all’interno di relazioni fiduciarie che consentono una rappresentazione positiva del sé. / The research is a qualitative exploratory study on the identity and social representations of the children living on the streets of Nairobi (Kenya). A number of representations of street children are shown and analysed(including the one – chokora – elaborated by the local community that assimilates the children to garbage) to demonstrate how the identity of the street children may be understood making reference to the subject as the product of social and cultural conditioning or as an entity possibly able – within a narrative continuity – to elaborate reflexively his own experience and to actively produce new meanings and social forms. Methodologically, forty-nine structured, twelve semi-structure and sixty-five in depth interviews were carried out with street dwellers, ex street boys, family members of street children, NGOs and CBOs’ social workers, privileged witnesses and individuals from the local community. Moreover, a visual technique (photo diary) and participatory observation were used. The empirical research has shown that the identity of the street children is formed on the relations of belonging and differentiation. Furthermore, social representations are determinant for the identity process of the street children, but there is also room for one’s own identity negotiation, in the light of the internal conversation, that allows a restructuring of the relational self around a positive mainstay. This happens when the negotiation of the identity is experienced as a relational process, oriented by the ultimate concerns, within trustworthy relations, that allow a positive representation of the self.

A partire dai primi anni Novanta il mondo ha assistito allo sviluppo ed al consolidamento di importanti organizzazioni e/o accordi a carattere regionale. Da allora il fenomeno dell' integrazione regionale si è notevolmente consolidato contribuendo allo sviluppo di un rinnovato interesse teorico verso il Regionalismo e, più in generale, verso i processi di integrazione regionale. Oggigiorno il Regionalismo è un tema centrale in diverse scienze sociali, ed in particolar modo nell’ambito dell’Economia Internazionale e delle Relazioni Internazionali. Concentrandosi su un ampio gruppo di accordi regionali caratterizzati dallo stretto rapporto tra il perseguimento dell’integrazione economica, da una parte, ed il raggiungimento di importanti fini geo-politici e nell’ambito della sicurezza dall'altra, lo scopo di questa ricerca è di dimostrare che un approccio multi-disciplinare è utile per un’analisi più completa ed approfondita di tali accordi, e nel caso specifico del Partenariato Euro-Mediterraneo. A tal proposito, i principali obiettivi del presente lavoro sono due: da una parte, analizzare se il Partenariato Euro-Mediterraneo ha effettivamente favorito lo sviluppo di un processo di integrazione regionale tra i Paesi del Bacino Mediterraneo; dall’altra, analizzare questa iniziativa alla luce dei principali contributi teorici dell’Economia Internazionale e delle Relazioni Internazionali. / Starting in the early 1990s the world witnessed the development and the strengthening of important regional organizations and arrangements. Since then many changes have occurred and the phenomenon of regional integration has strengthened. The recent upsurge in regional agreements has led to a renewed theoretical interest in Regionalism and regional integration processes. As a matter of fact, today Regionalism is a relevant issue for many social sciences; in particular, in the field of International Economics and International Relations. By focusing on a large group of regional agreements, which are characterised by a strong binomial relationship between economic integration and the achievement of geo-political and security goals, the purpose of the research is to demonstrate that a multi-disciplinary approach drawing from both International Economics and International Relations is necessary for a deeper understanding of such agreements. In order to test this line of reasoning, the present research will analyse a recent regional agreement: the Euro-Mediterranean Partnership. On the basis of the theoretical contributions on Regionalism and RIAs, the research will have two main aims: the first one is to analyse whether the Partnership has effectively contributed to the establishment of an integration process in the Mediterranean Basin, both in the political and in the economic spheres; the second one is to analyse the same initiative according to International Relations and the International Economics theories.

Programming PLC systems is limited by the provided libraries. In contrary, hardware-near programming needs bigger efforts in e. g. initializing the hardware. This work others a foundation to combine advantages of both development sides. Therefore, Portable.NET from the DotGNU project has been used, which is an implementation of CLI, better known as “.NET”. The target system is the PLCcore-5484 microcontroller board, developed by SYS TEC electronic GmbH. Built upon the porting, two variants to use interrupt routines withing the Portabe.NET runtime environment have been analyzed. Finally, the reaction times to occuring interrupt events have been examined and compared. / Die Programmierung für SPS-Systeme ist durch die gegebenen Bibliotheken beschränkt, während hardwarenahe Programmierung einen größeren Aufwand durch z.B.

Das Zielsystem ist das PLCcore-5484 Mikrocontrollerboard der SYS TEC electronic GmbH. Aufbauend auf der Portierung wurden zwei Varianten zur Einbindung von Interrupt-Routinen in die Portable.NET Laufzeitumgebung untersucht. Abschließend wurden die Reaktionszeiten zu eintretenden Interrupts analysiert und verglichen.

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.

I rapporti anglo-vaticani, storicamente segnati da reciproche diffidenze, si distinsero per cordialità nel corso della prima parte del pontificato di Papa Achille Ratti - Pio XI (1922-1939). Tra il 1927 e il 1932 un doloroso conflitto tra Chiesa e Stato a Malta, cattolicissima colonia britannica, si trasformò gradualmente in un aspro scontro diplomatico tra la Segreteria di Stato di Sua Santità ed il Foreign Office. I legami tra Regno Unito e Santa Sede si indebolirono ulteriormente nel biennio 1935-1936, durante la Guerra d’Etiopia: a torto, Londra interpretò l’iniziativa di pace della diplomazia pontificia come funzionale a sostenere le rivendicazioni imperiali dell’Italia fascista. Nel 1937, a seguito della pubblicazione dell’enciclica “Mit Brennender Sorge”, ebbe principio un effettivo riavvicinamento: gli inglesi percepirono il Papato allineato alle democrazie e contrapposto ai totalitarismi, ovverosia Germania e Italia. L’istituzione della Delegazione apostolica in Gran Bretagna (novembre 1938) costituiva sintomo e manifestazione concreta di tale nuova e profonda armonia. / Anglo-vatican relations, historically marked by reciprocal diffidences, were characterized by cordiality during the first part of the pontificate of Pope Achille Ratti - Pius XI (1922-1939). From 1927 to 1932 a painful conflict between Church and State in Malta, the Roman Catholic British colony, gradually turned into a bitter diplomatic confrontation between the Secretariat of State of His Holiness and the Foreign Office. The ties between United Kingdom and Holy See weakened further in the years 1935-1936, during the Ethiopian War: wrongly, London interpreted Papal Diplomacy’s peace initiative as conceived to support the imperial claims of Fascist Italy. In 1937, following the publication of the Encyclical “Mit Brennender Sorge”, a factual rapprochement started: the British perceived the Papacy as lined up with democracies and opposed to Totalitarian States, that is to say Germany and Italy. The institution of the Apostolic Delegation to Great Britain (November 1938) constituted symptom and concrete manifestation of a new and deep harmony.

L'indagine ha per oggetto il periodo americano di Luigi Sturzo (1940-1946), finora proco esplorato, soprattutto dal punto di vista delle fonti americane. E' stata messa in luce una serie di attività politiche e culturali, inquadrabili in precise strategie, volte alla diffusione dei valori della democrazia cristiana, a livello internazionale; alla formazione della classe politica; al più ampio sostegno alla patria lontana. / The essay focuses the American period of Luigi Sturzo (1940-1946), which has not been sufficiently explored until now, expecially from the point of view of the American archives data. It has been highlighted a series of political and cultural activitie set up by Sturzo, and which can be contestualized in the sense of precise strategies, directed to the diffusion of the values Christian Democracy, in the international background; to the formation of the ruling classes; to the wide support to the constitution of the democratic system in Italy.

Die unzureichende Schulpraxis ist einer der Hauptkritikpunkte, den die Studierenden des polyvalenten Lehramtsbachelors an der Universität Leipzig vorbringen. Besonders hoch sind daher die Erwartungen an die im regulären Verlauf des Studiums verankerten Schulpraktika: die Schulpraktischen Studien (SPS). Die SPS I sind dabei eng mit einem wahlobligatorischen Begleitseminar verbunden, in welchem die Studierenden Methoden der Schul- und Unterrichtsforschung kennenlernen und befähigt werden sollen, diese bei systematischen Beobachtungen und zur Analyse der Schulwirklichkeit anzuwenden. Diese Ziele sowie die Rahmenbedingungen zur Erreichung derselben werden im Folgenden einer Einschätzung durch Studierende und Dozierende unterzogen. Ausgehend von diesen Einschätzungen, soll zunächst die Qualität der SPS I in Bezug auf ihre Stärken und Schwächen aus Perspektive der Befragten beschrieben werden, um darauf aufbauend Verbesserungsvorschläge zu unterbreiten und somit zur Weiterentwicklung der SPS I als wichtigem Baustein beitragen zu können. Im Hinblick auf die Veränderungen im Zuge der Einführung des modularisierten Staatsexamens, wurden die Rahmenbedingungen im betreffenden Modul angepasst. Die Rückmeldungen aus dieser Studie sehen wir dennoch als wichtigen Beitrag zur Sicherung und Weiterentwicklung der Qualität der Lehramtsstudiengänge an der Universität Leipzig.

Questo lavoro intende analizzare il processo di evoluzione giuridica e sociale che ha operato nel mondo musulmano, con particolare riguardo alla condizione femminile e al diritto di famiglia nell’Islam. Date le connotazioni di specificità della giuridicità in ambito islamico, l’analisi delle modalità e degli strumenti con cui sono state portate avanti di volta in volta riforme e istituzionalizzazione di determinati ambiti giuridici consente di leggere l’Oggi con interessanti prospettive. Dopo una parte generale dedicata allo studio del diritto islamico e, in particolare, del diritto di famiglia, si è inteso analizzare il caso della Repubblica Islamica del Pakistan. Un caso oltremodo significativo nell’alternare Tradizione e Modernità e nelle peculiari evoluzioni istituzionali, sociali e politiche. È nella sua storia che si rintraccia sempre questa oscillazione, ma è soprattutto nella produzione normativa e nelle dinamiche sociali che si scopre quanto operino al suo interno meccanismi e movimenti di riforma che non esulano dai riferimenti islamici. Attraverso il periodo di fieldwork in loco, emerge l’immagine di un Paese non solo oggetto di un recente e contemporaneo processo di riforme legislative in materia penale e di diritto di famiglia, ma anche luogo di interessanti evoluzioni interpretative della giurisprudenza e di una società civile attiva e determinata verso l’affermazione di una “via musulmana alla modernità”. / This research aims to highlight the perspectives of reform within Islamic Family Law and in the field of women’s rights, focusing especially on the case of Pakistan. The study is structured in two main parts in the attempt to underline the dialectic between Tradition and Modernity. The first part is an analysis of the sources of Islamic Law, aimed to delineate, on one hand, the instruments of classical and reformist interpretation and the legal procedures which make possible an evolution of the Islamic law and, on the other hand, the influences of the customary practices, with special reference to Islamic Family Law. The second part focuses on the case of Pakistan. The purposes of this section are to analyze the reforms in the field of family law and women’s rights and to examine the significant trends and the debate addressing family law and the related eventual challenges and opportunities. As emerged during my fieldwork I spent in Pakistan, Islam per se cannot be considered the obstacle to modernization since many factors are affecting this process as patriarchal customary practices, poverty, lack of education and awareness, bureaucratic and judiciary inefficiencies. In this view, an effective reformation process could be started from social reforms, especially in the field of education, even the religious one, in order to produce an “attitudinal modernization” and a change in people’s mindset towards a culture of gender equity and respect.
