Children's potential mobility and appropriation of transport options in an informal settlementEl-Dorghamy, Ahmed 15 November 2018 (has links)
Die vorliegende Arbeit untersucht die tatsächliche und potenzielle Mobilität von Kindern aus einer informellen Siedlungsstruktur in einer Megacity des globalen Südens am Fall Ezbet El-Hagganas im Großraum Kairos; die Entwicklung von Mobilitätsgewohnheiten in der Kindheitsphase und bezieht sich dabei nicht nur auf Kinder als Nutzer, sondern berücksichtigt zudem deren unmittelbares soziales Umfeld und den gesamtgesellschaftlichen Kontext.
Der theoretische Rahmen für die Untersuchung der Mobilität von Kindern basiert auf Icek Ajzens Theorie des geplanten Verhaltens sowie auf Vincent Kaufmanns Konzeptualisierung des Motilitätsbegriffes. Primärdaten wurden in einer Feldstudie und in Fokusgruppen erhoben. Die Ergebnisse deuteten auf eine hohe Prävalenz der unabhängigen Mobilität von Kindern (child independent mobility, CIM) auf deren am häufigsten zu bewältigenden Strecke (zur Schule) hin, zunächst durch nicht motorisierte Formen der Verkehrsteilnahme, aber weitgehend auch mit Hilfe von verschiedenen formellen wie informellen Nahverkehrsmitteln. Es wurden sozio-kulturelle und sozialpsychologische Einflussfaktoren seitens sowohl Kindern als auch ihren Eltern identifiziert, die die Verkehrsteilnahme von Kindern hemmen oder befördern können. Gleichermaßen wurden hemmende Faktoren untersucht. Die Akzeptanz des Radfahrens von Kindern wurde als Fallbeispiel für unerschlossenes Mobilitätspotenzial untersucht und deutet auf die Prävalenz sozialpsychologischer Faktoren hin, die Entscheidungsfaktoren rationaler und praktischer Natur entgegenstehen und die die Verkehrsmittelnutzung von Kindern mindern; hier benannt als Nutzungslücke (appropriation gap). Die Ergebnisse wurden schließlich in Zusammenhang mit dem Konzept der Verkehrsteilnahme gestellt und erlauben die Diskussion von Implikationen für die politische Ebene und für den Diskurs von Mobilität in benachteiligten Gruppen der Gesellschaft. / This study investigates the nature of children's actual and potential mobility in a case study of an informal settlement in a megacity of a developing country; namely Ezbet El-Haggana in Greater Cairo and explores the nature of the childhood phase of developing mobility practices and habits, not only as enabled by children themselves as commuters, but also as enabled by parents and the surrounding community and society. A theoretical framework was constructed through which children's mobility is investigated. It is based on Icek Ajzen's Theory of Planned Behavior and Vincent Kaufmann's conceptualization of Motility. The data was primarily collected through a field survey and focus groups. Results indicated high prevalence of child independent mobility (CIM) in the most frequent trip (to school), not only through active transport but also largely through different formal and informal transport services available. There are socio-cultural and socio-psychological factors among both the parents and the children that constitute the appropriation of mobility options that cater to children, either enabling or inhibiting their mobility. Through the experiences of children's mobility, the acquired skills and adaptive attitudes by both children and parents enhance children's potential mobility compared to children in wealthier communities that may be granted less mobility rights or have less competences among other factors. Inhibiting factors were also investigated; the specific case of acceptance of cycling for children. This exemplified prevalence of socio-psychological factors that overshadow practical and rational aspects of choice; it is articulated here as an appropriation gap. Results were finally associated with the conceptualization of appropriation to discuss implications for policy and for the discourses of mobility in disadvantaged communities.

Estudo da corrosão por pite do aço AISI 409Souza, Juliana Sarango de January 2016 (has links)
Orientador: Prof. Dr. Renato Altobelli Antunes / Dissertação (mestrado) - Universidade Federal do ABC, Programa de Pós-Graduação em Nanociências e Materiais Avançados, 2016. / Os aços inoxidáveis são susceptíveis à corrosão por pite quando expostos à ambiente contendo íons agressivos. Esse fenômeno ocorre devido à quebra do filme passivo. O material estudado neste trabalho foi o aço inoxidável AISI 409. O comportamento de corrosão e a estabilidade do filme passivo foram investigados por ensaios eletroquímicos, utilizando as técnicas de espectroscopia de impedância eletroquímica, polarização potenciodinâmica, análise de Mott-Schotky e cronoamporometria. Os testes foram realizados em solução de 0,1 M de NaCl. Os pites formados foram visualizados por microscopia confocal a laser e tiveram suas dimensões medidas. Análise com MEV da amostra antes e após o ensaio de polarização foi realizado e locais de ocorrência dos pites foi registrado. Foram analisadas amostras na condição como-recebida e na condição solubilizada. O tratamento de solubilização foi realizado na temperatura de 1100 °C por 30 minutos, com o objetivo de homogeneizar a microestrutura dos materiais. Os resultados obtidos foram analisados e discutidos, dando ênfase para a compreensão do processo de corrosão por pite do aço inoxidável AISI 409 nas condições comorecebida e solubilizada. Foi verificada a presença de precipitados ricos em titânio nas amostras. Na amostra como-recebida, os precipitados compostos por Ti (C,N) colaboraram para o início da corrosão localizada. Na amostra solubilizada os precipitados foram identificados como TiN e a ocorrência da corrosão por pite foi dificultada. / Stainless steels are susceptible to pitting corrosion when exposed to environment containing aggressive ions. This phenomenon occurs due to the breakdown of the passive film. Stainless steel AISI 409 was studied in this work. The corrosion behavior and the stability of the passive film were investigated by electrochemical tests, using electrochemical impedance spectroscopy, potentiodynamic polarization, Mott-Shottky analysis and choronoamperometry measurements. The tests were carried out in NaCl 0.1 M solution. The pits formed were observed and measured by confocal laser scanning microscopy. SEM images were carried out before and after the potentiodynamic polarization and the regions associated with pitting formation were recorded. Samples were analyzed in the as-received and solutionized
conditions. The solution annealing treatment was performed at 1100 °C for 30 minutes in order to homogenize the microstructure of the materials. The results obtained were analyzed and discussed, giving emphasis to the understanding of the pitting corrosion behavior of the AISI 409 stainless steel in the as-received and solutionized states. The presence of titanium-rich precipitates in the samples was checked. In the as-received state, Ti (C,N) precipitates have contributed to the onset of pitting corrosion. For the solution annealed samples the precipitates were identified as TiN and the occurrence of pitting corrosion was difficult.

Le public organisé pour la lutte : le cinéma du peuple en France et la résistance du mouvement ouvrier au cinéma commercial (1895-1914) / The public organized for the fight : the cinéma du peuple in France and the resistance of the working class movement against the commercial cinema (1895-1914)Cezar Mundim, Luiz Felipe 22 August 2016 (has links)
La thèse examine la relation entre le mouvement ouvrier français et le cinéma au début du XXe siècle, plus précisément de 1895 à 1914. Elle s'articule autour de l'expérience spécifique de la coopérative Cinéma du Peuple, qui a duré d'octobre 1913 à juillet 1914. La coopérative Cinéma du Peuple participa à l'adhésion d'une partie des militants aux ressources du cinéma, sensible à partir de 1909, date à laquelle le processus d'industrialisation du film en France était déjà très avancé. Transmise au-delà de 1914, l'expérience du Cinéma du Peuple, première tentative ouvrière organisée d'appropriation du cinéma, a posé les fondements d'un nouveau terrain d'intervention en vue d'une hégémonie dans le champ culturel prolongée jusqu'à nos jours. L'hypothèse est que le public -catégorie d'analyse dans une échelle alternative de celle de masse, ou de spectateur -a montré, avec l'expérience du Cinéma du Peuple, qu'il n'est pas, par nature et de façon in-évocable, prisonnier des films commerciaux et des intérêts des distributeurs. À partir des notions de répertoire d'action, et de l'expérience de la domination idéologique par le cinéma commercial, nous nous efforçons de cerner les contours de ce public, pour partie confondu avec celui du mouvement ouvrier, notamment au moyen des trajectoires collectives et individuelles des initiateurs, propagandistes du Cinéma du Peuple et de ses spectateurs. En même temps, nous nous proposons de montrer à partir de l'analyse des films du Cinéma du Peuple le début de la formation d'un nouveau mode de représentation du monde ouvrier. / The thesis examines the relationship between the French working class movement and the cinema at the beginning of the 20th century, specifically from 1895 to 1914. 1t focuses on the specific experience of the cooperative Cinéma du Peuple, which lasted from October 1913 to July 1914. The cooperative Cinéma du Peuple took part of militant cinema in France, which was barely begun from 1909 on when the industrialization process of the film in France was already advanced. Transmitted beyond 1914, the experience of the Cinéma du Peuple, first working class movement organized attempt to film appropriation, laid the foundations of a new ground of intervention in a prolonged hegemony in the cultural field until the present days. The assumption is that the public - a category of analysis in an alternative scale than mass or spectator - showed, with the experience of Cinéma du Peuple, that it is not by nature and so irrevocable way a prisoner of the commercial films and the interests of distributors. From the concepts of repertoire of contention, and the experience of the ideological domination of commercial cinema, we strive to identify the contours of that public, partly coïncident with the working class movement, mostly through collective and individual militants' trajectories, propagandists of the Cinéma du Peuple and its public. At the same time, we intend to bring from the analysis of the Cinéma du Peuple's films the beginning of the formation of a new mode of representation of the working class.

Le contrôle temporel des consonnes occlusives de l’alsacien et du français parlé en Alsace / Timing of plosives in Alsatian and French spoken in AlsaceSteiblé, Lucie 11 December 2014 (has links)
Les Alsaciens ont, quand ils parlent français, un accent caractéristique. Ce phénomène peut être considéré, au niveau de la production de la parole, comme une perturbation qui engendre un certain nombre de variations des formes phonétiques attendues en français, notamment au niveau de la gestion temporelle des consonnes occlusives. Dans une lecture fondée sur l’importance du geste en tant qu’unité de base en production de la parole, il est possible d’analyser la plasticité de la gestion temporelle des sujets parlants, spécifiquement dans le cadre du bilinguisme. En effet, les gestes sont accomplis dans le but d’atteindre des cibles, avec néanmoins un certain degré de liberté et de variabilité visible tant au niveau articulatoire qu’acoustique. Il s’agit de respecter certaines contraintes, permettant de considérer le système de production / perception de la parole comme un ensemble ayant pour objectif l’émergence de solutions linguistiquement viables. Nous avons mené trois expériences, concernant la gestion temporelle des occlusives. Différents indices acoustiques ont été analysés, propres à l’alsacien, au français parlé en Alsace et à la parole de locuteurs imitant l’accent des Alsaciens. Les résultats obtenus sont analysés dans le cadre de la Théorie de la Viabilité, qui permet de mettre au jour le fonctionnement du système de production / perception de la parole, entre perturbation et réajustement. / French spoken by Alsatians has a clearly distinct accent. This could be regarded, from a speech production standpoint, as resulting from a perturbation which entails a number of variations of expected phonetic forms in French, especially with regards to timing of stops. Premised on the assumption that viewing gestures as the basic units in speech production is essential, the plasticity of speakers’ productions, more specifically within the context of bilingualism, was analysed in this study. Gestures are executed with the aim of reaching targets, with some degree of observable flexibility and variability, both articulatory and acoustic. Some constraints need to be respected, with the view that speech production and perception, as a coupled system, is geared towards a common objective : enable linguistically viable solutions to emerge. Three experiments were conducted pertaining to the temporal organisation of stops. Acoustic cues unique to Alsatian, to French spoken by Alsatians and to French speakers imitating Alsatians were analysed. Obtained results, were rationalised within the Viability Theory in order to highlight speech functioning, with reference to production and perception, that is, between perturbation and readjustment strategies.

Bambine e ragazzi bilingui nelle classi multietniche di Torino / Il sistema scolastico a confronto con opportunità, complessità e sfide del plurilinguismoRitucci, Raffaella 24 October 2018 (has links)
Das Schulregister des Kultusministeriums MIUR verzeichnet, dass mehr als jede/r zehnte aller Schüler/innen in Italien keine italienische Staatsbürgerschaft hat, obwohl sie mehrheitlich dort geboren wurden. Zahlreiche Erhebungen weisen für sie im Vergleich zu den italienischen Mitschülern/innen geringere Italienischkenntnisse und weniger schulischen Erfolg auf.
Innerhalb dieser explorativen Feldforschung haben Einzelinterviews mit 121 Schülern/innen (5.-8. Klasse) in Turiner Schulen und mit 26 Eltern, sowie die Auswertung von 141 an 27 Italienisch- und Herkunftsprachlehrer/innen verteilten Fragebögen ergeben, dass viele Schüler/innen "zweisprachige Natives" sind, da sie mit Italienisch und einer anderen Sprache aufwachsen. Dieser Polyglottismus, den die Interviewten sehr positiv bewerteten, findet jedoch in der Schulpraxis keine Entsprechung: Gezielte Förderung im Italienischen und der Unterricht der Familiensprache sind meist Wunschdenken.
In der Kohorte haben die Schüler/innen mit den besten Italienischkenntnissen einen italophonen Elternteil bzw. kamen im Vorschulalter nach Italien und besuchten dort den Kindergarten. Dagegen sind, wie auch bei den INVALSI-Tests, die in Italien geborenen und die dann die Krippe besuchten, leicht benachteiligt. Was die Familiensprache angeht, verbessert ihr Erlernen die Kompetenzen darin, ohne dem Italienischen zu schaden: Im Gegenteil. Diese Ergebnisse bestätigen die wichtige Rolle der "anderen" Sprache für einen gelungen Spracherwerb.
Das MIUR sollte also sein Schulregister mit Sprachdaten ergänzen, um die Curricula im Sinn der EU-Vorgaben umzuschreiben und den sprachlich heterogenen Klassen gezielte Ressourcen und definierte Vorgehensweisen zur Verfügung zu stellen. Mit geringeren Mitteln, im Vergleich zu den jetzigen Kosten für Herunterstufung, Klassenwiederholung und Schulabbruch würde man Schulerfolg, Chancengerechtigkeit und Mehrsprachigkeit fördern, mit positiven Folgen für den Einzelnen sowie für die Volkswirtschaft. / L'anagrafe studenti del MIUR registra come oggi in Italia più di uno studente su dieci non è cittadino italiano, pur essendo la maggioranza di loro nata in questo paese. Numerose indagini statistiche mostrano come gli allievi "stranieri" presentino, rispetto a quelli italiani, ridotte competenze in italiano e minore successo scolastico.
Questa ricerca esplorativa svolta in alcune scuole di Torino (V elementare-III media) ha analizzato dati ottenuti tramite interviste semi-strutturate a 121 studenti e 26 genitori e 141 questionari compilati da 27 insegnanti di italiano e di lingua di famiglia. Da essa è emerso che molti studenti sono "nativi bilingui", poiché crescono usando l'italiano e un'altra lingua. Questo poliglottismo, valutato dagli intervistati assai positivamente, non si rispecchia però nella prassi scolastica: un supporto mirato in italiano e l'insegnamento della lingua di famiglia sono di regola una chimera.
All'interno del campione le più ampie competenze in italiano si trovano fra chi ha un genitore italofono e chi è arrivato in Italia in età prescolare frequentandovi la scuola materna; come constatato anche nei test INVALSI, chi è nato in Italia e vi ha frequentato l'asilo nido è leggermente svantaggiato. Rispetto alla lingua di famiglia risulta che il suo studio porta a migliori competenze in essa, senza nuocere all'italiano: anzi. Emerge quindi il ruolo significativo della lingua "altra" per un'educazione linguistica efficace.
L'invito al MIUR è quindi di integrare la propria anagrafe con dati linguistici, così da ridefinire i propri curricula secondo le Linee Guida Comunitarie, individuando procedure e risorse specifiche per le classi multilingui. Con un investimento ridotto, paragonato con il costo attuale dato da retrocessioni, ripetenze e abbandono scolastico, si riuscirebbe a sostenere il successo scolastico, le pari opportunità e il plurilinguismo, con conseguenze positive per i singoli e per l'economia nazionale. / The Italian Ministry of Education (MIUR) student register records that today in Italy more than one out of ten students is not an Italian citizen, although the majority of them were born there. Several statistical surveys indicate that "foreign" students, when compared to native students, show a poorer performance in Italian and in academic achievement.
This exploratory fieldwork carried out in schools in Turin (5th to 8th grade) analyzed data obtained through semi-structured interviews with 121 students and 26 parents as well as 141 questionnaires filled in by 27 teachers of Italian and family language. It showed that many students are "bilingual natives", as they grow up acquiring both Italian and another language; however, despite the fact that the interviewees rate polyglottism positively, schools don't usually offer targeted support in either language.
Within the cohort the broadest range of competences in Italian are found first among those with an Italian-speaking parent, then among those who arrived in Italy at pre-school age attending kindergarten there; this latter group shows higher competences than those born in Italy attending nursery there, as also in the INVALSI tests. As far as family language is concerned, data illustrate that its teaching increases its competences without affecting those in Italian: quite the opposite in fact. These results confirm the remarkable role played by the "other" language in successful language education.
MIUR is therefore called upon to include also linguistic data in its student register, so as to redefine its curricula according to EU Guidelines, and to identify specific procedures and resources for multilingual classes. This new policy would reduce the current cost of placing students in a lower grade, grade retention and drop-outs, and would promote school success, equal opportunities and multilingualism, with positive consequences both for the individuals and for the national economy.
