Schwartz, Flora. "Raisonnement transitif et dyscalculie : étude par IRMf chez l’enfant." Thesis, Lyon, 2017. http://www.theses.fr/2017LYSE1332/document.
Full textAbstract:
Les dyscalculie se caractérise par d’importantes difficultés d’apprentissage des maths, malgré une scolarisation adéquat et des capacités intellectuelles dans la norme. Même si ce trouble affecte 3 à 7% des enfants d’âge scolaire, ses causes restent encore peu connues. Il a été proposé que la dyscalculie consiste en un déficit spécifique de représentation des quantités numériques, causé par des anomalies cérébrales au niveau du sillon intra-pariétal (IPS). Cependant, de plus en plus d’études suggèrent que la dyscalculie serait dûe à des atteintes cognitives générales. Cette thèse s’est intéressée au lien entre apprentissage des maths et une forme de raisonnement déductif, à savoir le raisonnement transitif (A>B, B>C donc A>C). Dans une première étude en Imagerie par Résonance Magnétique fonctionnelle (IRMf), nous avons comparé l’activité cérébrale d’enfants dyscalculiques de 9 à 12 ans à celle d’enfants neurotypiques de même âge pendant l’écoute d’histoires comprenant des problèmes transitifs. Dans une seconde étude, nous avons évalué l’amélioration en maths des enfants neurotypiques 1,5 an après la session IRMf. Nous avons déterminé si les mesures cérébrales associées au raisonnement transitif pouvaient prédire l’amélioration en maths. Nous avons mis en évidence l’implication de l’IPS gauche dans le raisonnement transitif chez les enfants neurotypiques mais pas chez les dyscalculiques, qui étaient moins précis pour évaluer les problèmes transitifs. Par ailleurs, les capacités de mémoire de travail étaient corrélées à la performance et à l’activité de l’IPS lors du raisonnement transitif. Enfin, l’activité cérébrale de l’IPS pendant le traitement des problèmes transitifs prédisait l’amélioration en maths chez les enfants neurotypiques. Ces résultats soulignent l’importance du raisonnement transitif pour l’apprentissage des maths et suggèrent qu’un déficit de traitement des problèmes transitifs dans l’IPS pourrait contribuer à la dyscalculieChildren who struggle to learn math despite normal intelligence and adequate schooling may suffer from dyscalculia. Although this learning disability may affect 3-7% of children worldwide, its causes remain poorly understood. Previous research has suggested that dyscalculia was due to a specific deficit in the processing of numerical magnitude that results from neural anomalies to the Intraparietal Sulcus (IPS). However, a growing body of studies has highlighted the domain-general deficits exhibited by children with dyscalculia. The goal of the present thesis was to investigate the neural relationship between math learning and a type of deductive reasoning, namely transitive reasoning (A>B, B>C, therefore A>C). In a first study, we used functional Magnetic Reasonance Imaging (fMRI) to measure brain activity in both typically developing (TD) children and chidren with dyscalculia while they listened to stories that included transitive relations. In a second study, we followed TD children longitudinally and to test whether brain measures of transitive reasoning could predict math improvement. First, the processing of transitive relations was associated with enhanced activity in the left IPS in TD children, but not in children with dyscalculia. Second, children with dyscalculia made more errors when processing transitive relations than TD peers. Third, IPS activity and behavioral performance was correlated with working-memory skill across all participants, suggesting that working memory impairments contribute to impaired transitive reasoning skills. Fourth, math gain in TD children was predicted by brain activity around the IPS during the processing of transitive relations. Therefore, the present findings show that measures of transitive reasoning are associated with math achievement. Our results further suggest that impaired neural processing of transitive relations in the IPS may contribute to math difficulties in dyscalculia

Aujourd'hui, le couple "jidôshi/tadôshi" s'emploie à la fois comme équivalent de celui des verbes transitif/intransitif des grammaires occidentales et pour désigner la diathèse des verbes -ji/ta japonais. Toutefois, il existe des divergences sur les plans morphologique, syntaxique entre les verbes -ji/ta et les verbes en transitif/intransitif. En fait, le couple "JI/TA" japonais a une histoire bien différente de celle de la catégorie de la transitivité occidentale. Ces deux traditions ne se croiseront qu'au 18ème siècle où les hollandologues japonais, pour traduire des grammaires néerlandaises, ont forgé les néologismes "jidôshi/tadôshi" comme équivalents des catégories verbales hollandaises "onzijdig woord/werkend woord". Nous montrons comment "jidôshi/tadôshi" et "JI/TA" indigène amalgament d'une part des résidus de diverses tentatives autochtones d'organisation systématique de phénomènes grammaticaux et d'autre part des catégorisations importées de théories grammaticales occidentalesToday, the "jidôshi/tadôshi" duo is used both as an equivalent to the conventional Western grammatical category of transitive/intransitive verbs and to designate the diathesis of ji/ta- verbs and transitive/intransitive verbs. Indeed, the Japanese "JI/TA" pair has a very different history from that of transitivity in the Western grammatical tradition. These two traditions didn't cross paths until the 18th century, when Japanese scholars of the Dutch language created the neologisms "jidôshi/tadôshi" as equivalents for the Dutch grammar methods. This dissertation aims to show how the "jidôshi/tadôshi" and indigenous "JI/TA" dichotomies combine the vestiges of various local attempts to systematically classify grammatical phenomena with categorizations imported from Western theories of grammar

Full textAbstract:
On considère R une relation d'équivalence borélienne standard de type I I1 sur un espace de probabilités (X, µ). On étudie une certaine propriété d'homogénéité pour un graphage fixé de la relation R : on suppose que les feuilles du graphage sont toutes isomorphes à un certain graphe transitif (connexe, infini, localement fini) Γ. Que peut-on dire sur la relation ? Dans ce cas, en considérant une action "à la Mackey", on montre qu'il existe (Z ,η) un revêtement standard probabilisé de (X, µ), une action libre (qui préserve η) sur Z du groupe G (localement compact, à base dénombrable d'ouverts) des automorphismes du graphe et un isomorphisme stable des groupoïdes mesurés associés. On fait le lien entre les propriétés du groupe G et celles de la relation de départ ; en particulier la propriété (T), (H) et la moyennabilité "passent" du graphe à la relation et réciproquement. On déduit aussi de la construction quelques couplages d'équivalence mesurée (ou plus généralement des "randembeddings") entre certains sous-groupes des automorphismes de Γ et tout groupe qui contient orbitalement la relation R. Dans un deuxième chapitre, on aborde le cas particulier de la propriété (T) relative pour les paires de groupes (ΓxZ^2, Z^2), où Γ est un sous-groupe non moyennable de SL(2,Z). Cette propriété a d'abord été prouvée par Marc Burger, puis "re-démontrée" plus "visuellement" quelques années plus tard dans le cas de SL(2,Z)xZ^2 par Y. Shalom, en utilisant des découpages du plan. On reprend cette technique dans le cas général du théorème de Burger afin d'obtenir par un algorithme des constantes de Kazhdan explicites pour toute paire (ΓxZ^2, Z^2).

Full textAbstract:
Notre objectif dans cette thèse est de vérifier la validité d'une formule équationnelle dans une spécification algébrique axiomatisée par un ensemble d'équations. Une formule équationnelle est une formule universellement quantifiée d'un langage du premier ordre dont les formules atomiques sont des équations simples. Nous proposons de généraliser et d'adapter les méthodes utilisées dans le cas des équations simples pour prouver la validité des formules équationnelles. Ainsi, dans le cas de la validité inductive nous avons utilisé l'induction structurelle basée sur la récurrence classique. Nous avons proposé une méthode pour la génération automatique des schémas d'induction dans certains cas particuliers. Dans le cas de la validité équationnelle nous avons proposé une méthode basée sur la transformation et la décomposition de la formule initiale pour déterminer un ensemble représentatif d'équations simples. La validité équationnelle de ces équations est équivalente à celle de la formule initiale. Un autre mécanisme de raisonnement appelé le chaînage transitif est proposé pour tester la validité des équations contenant des relations d'ordre. L'étude théorique des principes proposés dans cette thèse a abouti à la réalisation du système de preuve pause que nous avons utilisé pour vérifier certaines relations d'asynchronisme entre les composantes qui gèrent la communication dans un système parallèle

Full textAbstract:
Basée sur une analyse contrastive, cette thèse aborde la structure verbale en français et en russe. Son objectif est d’établir un regard réflexif sur les deux langues dans le but de déterminer la différence et la ressemblance dans leur construction verbale. Explorant la question des verbes de structure différente des langues concernées, elle tente également de trouver les difficultés provoquées par cette différence à l’apprentissage. Ainsi, dans cette recherche, on parle des verbes problématiques sous un angle aussi didactique que linguistique. Composé de trois chapitres, ce travail étudie dans un premier temps le statut transitif/intransitif des verbes dans les deux langues en traitant l’approche traditionnelle et moderne et met en place une étude contrastive par rapport à la question de valence. On explore la construction verbale avec complément dans le deuxième chapitre de la recherche. Dans cette partie, l’analyse parallèle des verbes est effectuée afin de repérer leur fonctionnement selon les moyens grammaticaux de chaque langue. Et finalement, la comparaison de chaque verbe considéré problématique à l’apprentissage des deux langues suivie de tableaux fait partie du dernier chapitre. La production des tests préliminaires effectués auprès des apprenants russophones constitue également cette partie pour mieux comprendre la difficulté de ces derniers lors de la communicationBased on a contrastive analysis, this thesis deals with the verbal structure in French and Russian. Its objective is to establish a reflexive look at the two languages in order to determine the difference and the similarity in their verbal construction. Exploring the question of the verbs of different structure, it also tries to find the difficulties caused by this difference in learning. Thus, in this research, problematic verbs are spoken of in a didactic as well as linguistic angle. This work, composed of three chapters, speaks first of all about the transitive/intransitive status of verbs in both languages by treating the traditional and modern approach and sets up a contrastive study in relation to the valence question. Verbal construction is explored with complement in the second chapter of the research. In this part, the parallel analysis of the verbs is performed in order to identify their functioning according to the grammatical means of each language. And finally, the comparison of each verb considered problematical to the learning in both languages followed by tables took the part of the last chapter. The production of preliminary tests with Russian-speaking learners is also part of this work in order to better understand the difficulties of the latter during the communication

This thesis presents time-series photometry of transits of 11 different extrasolar planets. Observations were conducted with the Fred L. Whipple Observatory 1.2m telescope and the Wise Observatory im telescope, in standard optical bandpasses. The number of transits observed for each planet ranges between one and 20 transits, and differential aperture photometry is performed for each transit observation. For the system TrES-2, this thesis examines 14 different different transit observations. Because of this large quantity of data, the parameters Rp/R., b, a/R., and i are also fitted for with precision using the Markov Chain Monte Carlo technique, and the resultant parameter values are presented. Transit-timing analysis is performed on all systems: CoRoT-2, GJ436, HAT-P-1, HD17156, HD189733, TrES-1, TrES-2, WASP-2, WASP-3, XO-1, XO-2, and XO-3. Transit timing is important both for constraining the orbital period and to search for variations in the transit-to-transit interval that could indicate the presence of an unseen companion planet. The transit center times for nearly all observations are found, and the planetary periods for all systems are calculated. In many cases these periods are determined with much greater precision than previously known. It is found that systems XO-2 and HAT-P-1 are consistent with a constant period, but our data are not conclusive with regards to the other systems.

Transmission spectra are differential measurements that utilize stellar illumination to probe transiting exoplanet atmospheres. Any spectral difference between the illuminating light source and the disk-integrated stellar spectrum due to starspots and faculae will be imprinted in the observed transmission spectrum. However,. few constraints exist for the extent of photospheric heterogeneities in M dwarfs. Here we model spot and faculae covering fractions consistent with observed photometric variabilities for M dwarfs and the associated 0.3-5.5. mu m stellar contamination spectra. We find that large ranges of spot and faculae covering fractions are consistent with observations and corrections assuming a linear relation between variability amplitude, and covering fractions generally underestimate the stellar contamination. Using realistic estimates for spot and faculae covering fractions, we find that stellar contamination can be more than 10x. larger than the transit depth changes expected for atmospheric features in rocky exoplanets. We also find that stellar spectral contamination can lead to systematic errors in radius and therefore the derived density of small planets. In the case of the TRAPPIST-1 system, we show that TRAPPIST-1 ' s rotational variability is consistent with spot covering fractions f(spot) = 8(7)(+18)% and faculae covering fractions f(fac) = 54(-46)(+16)%. The associated stellar contamination signals alter the transit depths of the TRAPPIST-1 planets at wavelengths of interest for planetary atmospheric species by roughly 1-15x. the strength of planetary features, significantly complicating JWST follow-up observations of this system. Similarly, we find that stellar contamination can lead to underestimates of the bulk densities of the TRAPPIST-1 planets of Delta(rho) = -8(-20)(+7)%, thus leading to overestimates of their volatile contents.

The disruption of the Earth system’s ecological cycles and climate change, mainly caused by a global social metabolism based on fossil fuels, call for the international community to look for changes within global governance strategies towards a sustainable development model not based on fossil fuels. The challenge posed by this new economic development model and by this new social organization relies on how to operate within planetary boundaries from a justice perspective. In this global context, the Mexican energy transition policy is the response to the international commitments undertaken by the government regarding climate change. This doctoral thesis intends to analyze all the steps taken in the national energy policy context, from planning to implementation, all from a justice perspective. In this sense, some analytical tools, like environmental justice, climate justice and energy justice, are used to critically evaluate this policy. The main research question is whether relies on the elements that the Mexican government should consider for the implementation of the energy police, in terms of justice.

This thesis explores and evaluates the essential strategies needed for transit agencies to switch from traditional fare collection systems to smart cards. More transit agencies today are investing in smart card technology as part of their new automated fare collection (AFC) systems. Although the benefits of switching to smart card systems have been well-researched and acknowledged by transit agencies, it is unclear how a transit agency should go about implementing a smart card system in order to achieve optimum customer acceptance and to reap maximum benefits from the system. Recent experience has shown that a range of implementation policy decisions can go a long way towards speeding or slowing down the adoption of the technology by customers. A case study approach is used here to identify and evaluate the effectiveness and impacts of policies used by five transit agencies that currently employ smart cards. These policies fall into two categories: 1) distribution, operational and usage policies, and 2) fare policies. Distribution, operational and usage policies must be designed to facilitate and enhance customer adoption of smart cards, especially in the case where alternative fare media will co-exist.
(cont.) Fare policies are designed to differentiate smart cards from other fare media through differential pricing strategies, frequent-use bonuses and low price guarantees. The thesis also examines the use of fare models in assisting transit agencies to predict ridership and revenue, especially focusing on the features needed in these models to predict the usage rates of smart cards and their associated unique fare options. Finally, the findings from the research are integrated and used to develop a set of guidelines for use by a transit agency that is switching to a smart card fare payment system. The main topics of these guidelines were identified as: 1) the use of fare policy incentives, 2) balance between restrictions and alternatives with respect to co-existing fare media, 3) accessibility to smart card support services, 4) capitalizing on the superiority of smart card technology, and 5) the use of a single card. To illustrate the usefulness of the guidelines, they were applied to a case study of the Massachusetts Bay Transportation Authority (MBTA)'s new AFC program, the CharlieCard.

Transits of exoplanets observed in the near-UV have been used to study the scattering properties of their atmospheres and possible star-planet interactions. We observed the primary transits of 15 exoplanets (CoRoT-1b, GJ436b, HAT-P-1b, HAT-P-13b, HAT-P-16b, HAT-P-22b, TrES-2b, TrES-4b, WASP-1b, WASP-12b, WASP-33b, WASP-36b, WASP-44b, WASP-48b, and WASP-77Ab) in the near-UV and several optical photometric bands to update their planetary parameters, ephemerides, search for a wavelength dependence in their transit depths to constrain their atmospheres, and determine if asymmetries are visible in their light curves. Here, we present the first ground-based near-UV light curves for 12 of the targets (CoRoT-1b, GJ436b, HAT-P-1b, HAT-P-13b, HAT-P-22b, TrES-2b, TrES-4b, WASP-1b, WASP-33b, WASP-36b, WASP-48b, and WASP-77Ab). We find that none of the near-UV transits exhibit any non-spherical asymmetries, this result is consistent with recent theoretical predictions by Ben-Jaffel et al. and Turner et al. The multiwavelength photometry indicates a constant transit depth from near-UV to optical wavelengths in 10 targets (suggestive of clouds), and a varying transit depth with wavelength in 5 targets (hinting at Rayleigh or aerosol scattering in their atmospheres). We also present the first detection of a smaller near-UV transit depth than that measured in the optical in WASP-1b and a possible opacity source that can cause such radius variations is currently unknown. WASP-36b also exhibits a smaller near-UV transit depth at 2.6 sigma. Further observations are encouraged to confirm the transit depth variations seen in this study.

Adolescence is one the most challenging stages for a person with Type 1diabetes. Despite the significant importance of tailoring healthcare services to adolescents? unique needs including their rapid psychosocial growth and development, high quality adolescent healthcare services are not universal in the United States. The current system of health services is ill suited for providing the proper mix of clinical and preventative services to youth. According to the Consensus Statement on Health Care Transition for Young Adults with Special Health Care Needs, ?each year more than half a million children with disabilities and chronic illness transition from adolescence into adulthood?.
In response to the need for transition care the National Diabetes Education Program transition-planning checklist was adapted and implemented for use with youth ages 16-22 years in a primary care clinical practice to provide a more structured process in healthcare transition planning for providers and patients.
The project took place at Sanford Health children?s diabetes department in Fargo, North Dakota from July 2015 through December 2015. The checklist was used by healthcare providers to introduce the concept of transition and topics important to successful transition in the future. After implementation, use of the tool with qualified patients and evaluation of provider feedback about the checklist was used to improve utility of the evidence-based checklist in practice application for future use.
Across six months of implementation, 25% of all eligible youth with Type 1 diabetes seen were presented the transition-planning checklist. The providers agreed the transition-planning checklist incorporated good structure and content. All providers desired to continue to use the checklist in the future to provide transition-planning care to youth with Type 1 diabetes. Providing holistic care for youth with Type 1 diabetes is important for successful transition to adult care services. Implementing a transition ?planning checklist in the children?s diabetes department was found to be helpful and well received despite limited use (25% of eligible patients). Future efforts should be made to extend the project to be more inclusive of all areas needed for successful transition.

Thesis (M. Tech. (Business Administration)) -- Central University of Technology, Free State, 2014This exploratory study seeks to contribute to the theoretical and empirical understanding of the transition of small businesses from the informal to the formal sector. It builds on the role of the informal sector as “engines” for economic and socio-cultural development. Using selected businesses in the Mangaung area of the Free State province as case studies, this study investigates the motives for transition of informal businesses to the formal sector in South Africa, challenges encountered in the process of formalisation and the coping strategies relied upon to deal with challenges encountered in the process of formalisation. Key indicators were identified from the literature and were further developed for investigation. A qualitative approach was used for the collection of data from selected transited businesses in the Bloemfontein area using semi-structured interviews. Findings from the study suggest that the decision by small business owners to formalise is motivated by their desire to grow and expand their businesses; access to proper banking services; and to access government contracts and tenders. The results also reveal that the quest for growth is however hindered by long queues endured by business applicants during the process of formalisation; lack of adequate and relevant information on the process of formalisation; coupled with the lack of government support for informal businesses’ transitioning to the formal sector. Findings further revealed that adequate information on the process of formalisation and self-trust are key coping mechanisms needed by small business owners to successfully progress/ transit to the formal sector. Based on these findings, the study recommends that government both provincial and national play a more proactive role in regulating the informal economy by creating an environment conducive for their growth and development, and facilitating their transition to the formal sector. Informal small business owners also must be provided with information on the process of formalisation and of the existing government structures put in place to support businesses in their transition phase.

TRANSITION is an installation of films that engages the histories of the bombings of Hiroshima and Nagasaki to the meltdown of Fukushima Daiichi in 2011—it is an attempt to bridge the gap of nuclear issues that are still present today. I redirect found images from their institutional contexts to reposition them as a dialogue between the archival and my own footage. All histories are told through media, and all mediations are remediation of the event. Histories are never fixed, but are constantly reproduced by different groups who are involved.

Full textAbstract:
Cancer cells undergo epithelial-to-mesenchymal transition (EMT) to dissociate from the primary tumor and to survive to chemotherapy. EMT is controlled by Snail1, a transcriptional factor also required for the activation of cancer-associated fibroblasts (CAFs). Snail1 is short-lived in normal epithelial cells as a consequence of the coordinated and continuous ubiquitination by several F-box specific E3 ligases. We have performed a siRNA screening to identify deubiquitinases (enzymes removing the ubiquitin chains conjugated to a substrate), increasing Snail1 stability and identified the Ubiquitin Specific Protease 27X (USP27X) as an enzyme that interacts with, deubiquitinates and stabilizes Snail1. We observed that USP27X modulate EMT features through the stabilization of Snail1, such as tumor cell invasion, cancer metastasis and chemo-resistance. In addition, USP27X is essential for the TGFβ-induced EMT and the activation of CAFs modulated by this cytokine. To summarize, we identified USP27X as a new modulator of Snail1 stabilization and its repression could prevent the metastatic and chemo-resistant proteins of the tumoral cells.Les cèl·lules canceroses inicien un procés anomenat transició epiteli-mesènquima (EMT, per l’acrònim en anglès de epithelial-to-mesenchymal transition), per escapar del tumor primari i tornar-se resistents a la quimioteràpia. Aquest procés està estrictament regulat pel factor de transcripció Snail1 que, a més a més, és requerit per l’activació dels fibroblasts que envolten el tumor. Snail1 és una proteïna amb una vida mitja molt curta en les cèl.lules epitelials; això es deu a que és contínuament ubiqüitinat per l’activitat coordinada que exerceixen diferents enzims anomenats ligases d’ubiqüitina. Fent un screening de siRNAs, vam identificar deubiqüitinases (enzims que remouen la ubiqüitina) que podrien estar involucrades a l’estabilització de Snail1 i vam caracteritzar la USP27X com un enzim que interacciona, deubiqüitina i estabilitza aquest factor. Vam observar que USP27X modula a través de l’estabilització d’Snail1 trets relacionats amb la EMT com la invasió, la metàstasi i la quimioresistència de les cèl·lules tumorals. A més a més, USP27X és crucial per la inducció de la EMT i l’activació de fibroblasts depenents de TGFβ. En resum, hem caracteritzat USP27X com una proteïna clau en el control de l’estabilització d’Snail1 i el bloqueig d’aquesta deubiqüitinasa podria contrarestar les capacitats metastàtiques i quimioresistents de les cèl·lules tumorals.

Full textAbstract:
The activation of Notch1 receptor triggers differential outcomes depending on the upstream activating ligand. This way, Jag1-Notch1 activation promotes endothelial to hematopoietic transition process for the generation of hematopoietic stem cells, whereas Dll4-Notch1 activation promotes vasculo-arterial specification.
Nevertheless, the mechanistics that selectively induce one fate or the other have not been characterized so far. Therefore, this thesis work aimed to uncover the particulars of how Notch pathway orchestrates HSC specification in the aorta-gonad-mesonephros region.
We have shed light on the particular effects triggered by Jag1 and Dll4 ligands and we propose a cross-talk regulation between the two ligands as the mechanism by which Notch acquires the right signal strength and exerts the decision between arterio-endothelial and hematopoietic fate specification.L’activació del receptor Notch1 comporta resultats diferencials que depenen del lligand que l’activi a un nivell superior de la via. D’aquesta manera, l’activació Jag1-Notch1 promou el procés de transició endoteli-hematopoètica per la generació de cèl•lules mare hematopoètiques, mentre que l’activació Dll4-Notch1 promou l’especificació vasculo-arterial. No obstant això, els mecanismes que indueixen selectivament un destí o altre no han estat caracteritzats. Per aquest motiu, aquesta tesi té per objectiu caracteritzar com la via de Notch dirigeix l’especificació de cèl•lules mare en la regió de l’aorta-gonada-mesonefros. En aquest treball hem caracteritzat els efectes específics activats pels lligands Jag1 i Dll4 i proposem una regulació creuada entre aquest dos lligands com a mecanisme per mitjà del qual Notch assoleix el nivell d’activació requerit per decidir entre especificació arterio-endotelial i destí hematopoètic.

Aquesta investigació analitza el potent moviment veïnal que es va configurar durant els darrers anys del franquisme i la transició al Barcelonès Nord, sub-comarca que agrupa als municipis de Badalona, Santa Coloma de Gramenet i Sant Adrià de Besòs, situats al nord de Barcelona. Aquestes poblacions van experimentar un gran creixement demogràfic a partir de la dècada dels 40 i 50 del segle XX, quan es va reprendre l'arribada de població d'altres indrets de l'Estat espanyol.
La lluita diària per millorar l'existència a uns barris on predominava l'infrahabitatge va donar pas a una primerenca organització. Les autoritats franquistes van intentar controlar aquests barris fomentant un model particular d'associacionisme. No obstant aquests intents de control no van acabar de reeixir per l'acció altres factors que van afavorir la configuració d'un potent sentiment d'identificació col·lectiva i de classe que va propiciar el posterior esclat del moviment veïnal.
L'acció d'organitzacions catòliques de base i d'un grup de sacerdots joves que van impulsar un apostolat diferent als barris obrers d'aquestes tres ciutats, juntament amb el paper dels militants antifranquistes van ser cabdals. Els partits polítics d'esquerres marxistes i d'altres organitzacions tradicionalment havien prioritzat el treball a les fàbriques, però progressivament anaren donant més importància a l'acció als barris fins arribar, als anys setanta, a considerar-lo un front de lluita equiparable al sindical.
Va ser als anys setanta quan van esclatar amb tota la seva força un conjunt de lluites als diferents barris de les ciutats del Barcelonès Nord, ja fossin impulsades per Centres Socials, Comissions de Barri i finalment les Associacions de Veïns. Els motius inicials van ser les mancances materials dels habitatges i de tot tipus de serveis bàsics. Però aviat es van sumar reivindicacions més polititzades contra la dictadura i reclamant uns Ajuntaments democràtics, amb un discurs molt crític amb el sistema capitalista. Les autoritats franquistes locals es van veure desbordades.
En el camí per la instauració dels Ajuntaments democràtics el moviment veïnal va viure un moment de crisi entre d'altres motius per la marxa de dirigents veïnals per assumir responsabilitats als nous ajuntaments, pel debat sobre quin hauria de ser el paper del moviment en el nou context polític, la crisi de les diferents formacions d'esquerres així com per l'impacte de la mateixa crisi econòmica. No obstant, això no va comportar la desaparició del moviment veïnal ja que durant els anys vuitanta encara van existir conflictes amb una intensitat comparable a la de la dècada anterior, si bé ara responien més a reaccions defensives i no hi havia una voluntat clarament assumida per sectors amplis de població per canviar el sistema polític com si havia succeït amb la lluita veïnal contra la dictadura.Esta investigación analiza el potente movimiento vecinal que se configuró en los últimos años del franquismo y la transición en el Barcelonès Nord, sub-comarca que agrupa a los municipios de Badalona, Santa Coloma y Sant Adrià de Besòs, situados al norte de Barcelona. Estas poblaciones experimentaron un gran crecimiento demográfico a partir de la década de los 40 y 50 del siglo XX, cuando se reanudó la llegada de población de otros lugares del Estado español. La lucha diaria para mejorar la existencia de unos barrios donde predominaba la infravivienda dio paso a una temprana organización. Las autoridades franquistas intentaron controlar estos barrios fomentando un modelo particular de asociacionismo. No obstante estos intentos de control no acabaron de cuajar por la acción otros factores que favorecieron la configuración de un potente sentimiento de identificación colectiva y de clase que propició el posterior estallido del movimiento vecinal. La acción de organizaciones católicas de base y de un grupo de sacerdotes jóvenes que impulsaron un apostolado diferente en los barrios obreros de estas tres ciudades, junto con el papel de los militantes antifranquistas fueron cruciales. Los partidos políticos de izquierdas marxistas y otras organizaciones tradicionalmente habían priorizado el trabajo en las fábricas, pero progresivamente fueron dando más importancia a la acción en los barrios hasta llegar, en los años setenta, a considerarlo un frente de lucha equiparable al sindical. Fue en los años setenta cuando estallaron con toda su fuerza un conjunto de luchas en los diferentes barrios de las ciudades del Barcelonès Nord, ya fueran impulsadas por Centros Sociales, Comisiones de Barrio y finalmente las Asociaciones de Vecinos. Los motivos iniciales fueron las carencias materiales de las viviendas y de todo tipo de servicios básicos. Pero pronto se sumaron reivindicaciones más politizadas contra la dictadura y reclamando unos Ayuntamientos democráticos, con un discurso muy crítico con el sistema capitalista. Las autoridades franquistas locales se vieron desbordadas. En el camino para la instauración de los Ayuntamientos democráticos el movimiento vecinal vivió un momento de crisis entre otros motivos por la marcha de dirigentes vecinales para asumir responsabilidades a los nuevos ayuntamientos, por el debate sobre cuál debería ser el papel del movimiento en el nuevo contexto político, la crisis de las diferentes formaciones de izquierdas así como por el impacto de la misma crisis económica. No obstante, esto no supuso la desaparición del movimiento vecinal ya que durante los años ochenta todavía existieron conflictos con una intensidad comparable a la de la década anterior, si bien ahora respondían más a reacciones defensivas y no había una voluntad claramente asumida por amplios sectores de población para cambiar el sistema político como si había sucedido con la lucha vecinal contra la dictadura.
This research examines the powerful urban social movement origineted during the last years of francoist dictatorship and time known as 'the transition', at Barcelonés Nord. At the North of the city of Barcelona this area is formed by the towns of Badalona, Santa Coloma de Gramenet and Sant Adrià de Besòs. The Barcelonés Nord have a large population growth since the early 40s and 50s of the twentieth century, when the arrival of people from other parts of the Spanish state was restarted. The daily struggle to improve life in the neighborhoods, where substandard housing was predominated, ushered in an early organization. Francoist authorities tried to control these neighborhoods by encouraging particular model of association. Despite these attempts at control did not succeed to finish action other factors that favor the formation of a strong sense of collective identity and class that led to the subsequent outbreak of local movement. The action of catholic worker's organizations also of a group of young priests who promote a different apostolate in these towns' working-class neighborhoods and the performance of the anti-Franco activists were crucial. The leftist Marxist political parties and other organizations have traditionally prioritized work in factories, but gradually be given more importance in the neighborhoods until the seventies, to consider it comparable to a battlefront union. It was in the seventies when it erupted in full force a series of struggles in different neighborhood of the towns of Barcelonés Nord, whether driven by social centers, neighborhood committees and also neighborhood associations. The initial reason was the poor construction and lack of any kind of service. But soon joined more politicized claims against dictatorship and demanding a democratic councils with a speech highly critical of the capitalist system. Francoist local authorities were overwhelmed. In order to establish democratic councils the neighborhood movement experienced a moment of crisis among other reasons for the departure of neighborhood leaders to take responsibility for the new councils, the debate on what should be the role of the movement in the new context political, crisis of the different leftist groups and, as well, because of the concern of the economic crisis itself. However, this did not lead to the disappearance of the local movement since the eighties there were still conflicts with an intensity comparable to of the previous decade, although now more responsive to defensive reactions and there was a will clearly assumed by large sectors of the population to change the political system as if it had happened to the neighborhood struggle against the dictatorship.

Full textAbstract:
Esta tesis presenta una serie de estudios computacionales basados en métodos de estructura electrónica en los que se analizan la anisotropía magnética y las propiedades derivadas de esta en complejos magnéticos candidatos a imán molecular y bit cuántico con la particularidad de tener un espín total S = ½. En los primeros tres capítulos de esta tesis se estudian complejos de metales de transición. Por otro lado, el cuarto y último capítulo se centra en analizar complejos de lantánidos, concretamente de YbIII.
En el primer capítulo se incluye un trabajo a través del cual se relaciona la configuración electrónica y la geometría de coordinación de un compuesto con su anisotropía magnética, en la forma del tensor g. Se puede establecer dicha conexión gracias a la dependencia del tensor g con la energía de los orbitales d. Esta energía se obtiene mediante cálculos ab initio analizados con el modelo de AILFT. Estos se realizan a partir de la función de onda obtenida en cálculos NEVPT2 realizados en modelos sencillos [MIILn], siendo MII el correspondiente metal divalente de la primera serie de transición con S = ½, L ligandos NH3 Cl- y n un número de coordinación entre 2 y 8. La observación de una anisotropía magnética de eje fácil fuerte indicar la presencia de un posible imán unimolecular mientras que una anisotropía débil es adecuada para presentar comportamiento de bit cuántico.
El segundo capítulo realizado en colaboración con el grupo de “Molecular Magnetism and Quantum Computing” dirigido por el Dr. Alejandro Gaita Ariño del Institut de Ciència Molecular de Valencia (ICMol), se centra en el estudio del acoplamiento espín-fonón en tres bits cuánticos de VIV: [VOPc], [VO(dmit)2]2- y [V(dmit)3]2- donde Pc es el ligando ftalocianina y dmit es el ligando 2-tioxo-1,3-ditiol-4,5-ditiolato. A través de la variación que se produce en la anisotropía magnética al deformarmse las distintas moléculas debido al movimiento de cada modo vibracional, se calculó la fuerza del acoplamiento espín-fonón correspondiente a los distintos estados vibracionales, mediante cálculos a nivel NEVPT2/AILFT. Esta magnitud se utilizó para entender las diferencias en los tiempos de coherencia para los distintos sistemas estudiados.
El tercer capítulo, finalizando el bloque dedicado a metales de transición, recopila una serie de colaboraciones con distintos grupos experimentales. Se realizó un análisis computacional similar al delos capítulos anteriores para cada compuesto en concreto: estudio de la estructura electrónica mediante cálculos NEVPT2/AILFT, anisotropía magnética en base a los orbitales d de cada compuesto, y comparación de las distintas propiedades magnéticas calculadas con las medidas experimentales. Además, se realizó el ajuste de los tiempos de relajación del espín, examinando los distintos mecanismos de relajación posibles en cada caso.
En el último capítulo se analizó el caso del YbIII, un lantánido con S = ½, haciendo uso de cálculos CASPT2+RASSI con el programa MOLCAS. Dichos cálculos de estructura electrónica se realizaron en una serie de modelos [Yb(H2O)n]3+ y [Yb(OH)3(H2O)n-3], utilizando geometrías ideales para números de coordinación entre 2 y 10. Estos cálculos muestran el efecto de la geometría de coordinación y la distribución de carga de los ligandos sobre propiedades fundamentales como la energía de los distintos estados electrónicos, la anisotropía magnética del estado fundamental, o las probabilidades para los distintos mecanismos de relajación. A partir de estos resultados se explican las propiedades como imanes unimoleculares de los sistemas de YbIII encontrados en la bibliografía y se propusieron una serie de geometrías adecuadas para el fenómeno de imán unimolecular en estos sistemas.This thesis presents a series of theoretical studies based on electronic structure methods to analyze the magnetic anisotropy and other related properties of magnetic complexes with total spin S = ½. The first three chapters are devoted to transition metal complexes while the fourth one addresses lanthanides systems, specifically YbIII. The first chapter determines a relationship between the d orbitals occupation and the coordination geometry of S = ½ transition metal complexes with their magnetic anisotropy, through its g-tensor. This connection is possible due to the relationship between the g-tensor and the splitting of the d manyfold. These energies were obtained using NEVPT2/AILFT calculation on [MIILn] models, screening for different MII metals, coordination numbers (n) and geometries, and ligand nature (L = NH3 or Cl-). The second chapter is a study carried out in collaboration with Dr. Gaita Ariño’s group from the molecular Science Institute of Valencia (ICMol) analyzing the spin-phonon coupling in three VIV qubits: [VOPc], [VO(dmit)2]2- y [V(dmit)3]2-, being Pc = Phthalocyanine and dmit = 1,3-dithiole-2-thione-4,5-dithiolate. In order to analyze the spin-phonon coupling we examined the variation of the magnetic anisotropy using NEVPT2/AILFT calculations for each vibrational mode. The spin-phonon coupling constants obtained for the vibrational modes in the three complexes were used to rationalize their different decoherence times. The third chapter, the last one dedicated to transition metal complexes, compiles a series of collaborations with experimental groups. In these studies, using the same methods as in the previous chapters, we analyzed the electronic structure and magnetic properties of the compounds, explaining experimental results through theoretical calculations. Also, we fitted the spin relaxation times considering the all possible spin relaxation mechanisms. Finally, the fourth chapter explores the magnetic anisotropy and electronic structure of YbIII compounds on the basis of theoretical calculations in a series of [Yb(H2O)n]3+ y [Yb(OH)3(H2O)n-3] model using ideal geometries corresponding to coordination numbers between 2 and 10. These calculations explain the properties of the YbIII single-molecule

Full textAbstract:
This research project aimed to provide a more elaborate understanding of mothers' views regarding their child with learning disabilities' transition to adulthood. In particular, the researcher focused on how mothers conceptualised "transition", the role that mothers' relationships with services would play, and mothers' experiences of social structures. Individual semistructured interviews were conducted with seven mothers of young people (16-23 years) with learning disabilities; yielding information on their views and experiences of transition. Thematic analysis within a critical realist epistemological framework was utilised as an analytic methodology. Mothers' were found to conceptualise transition as a complex, life long, worrying process informed by previous experiences of transitions. Mothers considered transition to adulthood as marked by a transition to "independence"; however, the meaning of independence varied amongst the sample. Mothers' visions of their children's adult futures included ideas about social relationships, employment and development of sexuality. The transition process was positioned within important peripheral issues including mothers' predominantly negative reports of service provision, with some helpful exceptions and resources available to mothers external to service provision. Mothers' commitment to their children was demonstrated throughout the data, and was often spoken about in terms of "fighting talk" whereby mothers were campaigning for improved service provision. The implications for professionals working with mothers are to improve partnership working with mothers in preparing for transition and improving service provision more generally. A recognition by services of mothers' needs and alternative identities aside from their role as "maternal caregiver" is recommended.

A group G is called a barely transitive group if it acts transitively and faithfully on an infinite set and every orbit of every proper subgroup is finite.
A subgroup H of a group G is called a permutable subgroup, if H commutes with every subgroup of G. We showed that if an infinitely generated barely transitive group G has a permutable point stabilizer, then G is locally finite.
We proved that if a barely transitive group G has an abelian point stabilizer H, then G is isomorphic to one of the followings:
(i) G is a metabelian locally finite p-group,
(ii) G is a finitely generated quasi-finite group (in particular H is finite),
(iii) G is a finitely generated group with a maximal normal subgroup N where N is a locally finite metabelian group. In particular, G=N is a quasi-finite simple group.
In all of the three cases, G is periodic.

Transition Economics focuses on the transformation of a socialist economic system to market economy, which is of interest both because of its policy relevance and its importance to economic theory. As transition was one of the most important economic events of the last century, the study of Transition Economy may help us to understand the difficulties, surprises, and obstacles when a society undergoes profound change. Moreover, it may develop our knowledge of the capitalist economic system and its institutions. The dissertation consists of two different topics within Transition Economics. The first three papers, based on three different data sets, focus on various aspects of the Russian labour market. Theses papers include analyses about the ways people search for work, how unemployment duration is affected by different characteristics, but also how people divide the time outside the paid labour market. This may provide new insights on the Russian labour market, and hopefully also deepen our understanding of labour markets in general. The fourth paper, based on a fourth data set, takes a macro perspective and is concerned with transition and terrorism. It has been claimed that with new democracies, an increased risk of terrorism follows. Therefore, in the final paper, the potential connection between terrorism and transitional progress is analysed.

The substantial recent advances in early universe observational cosmology have confronted theoretical physics with a number of deep conceptual questions. The standard model of particle physics and its natural extensions have proven to be insufficient for explaining the recent observations. String theory as the main candidate for a complete theory of quantum gravity provides us with the possibility of resolving this discrepancy. In this dissertation, I begin by an overview of thermodynamics in string theory. The issue of stability and the existence of the thermodynamic limit have been addressed. I will describe the string gas cosmology in detail, as the leading candidate of early universe cosmology. Successes and shortcomings of the most recent model of string gas cosmology in matching with observations are addressed. I conclude with comments on interesting directions for future study and a possible link with black hole physics.A la lumiere des plus recentes observations cosmologiques, la physique theorique se trouve confrontee a de nombreuses questions conceptuelles. Le Modele Standard de physique des particules et ses plus simples extensions se sont averes insuffisants pour expliquer les recentes observations. La theorie des cordes, qui est presentement la principale candidate pour une theorie complete de la gravite quantique, nous offre la possibilite de resoudre ces lacunes du Modele Standard. Nous debutons cette these par un apercu de la thermodynamique dans la theorie des cordes. Nous nous penchons en particulier sur la stabilite et sur l'existence d'une limite thermodynamique en theorie des cordes. Nous presentons par la suite les details de la cosmologie des gaz de cordes et discutons des succes et des problèmes de cette approche pour decrire l'evolution cosmologique du debut de l'univers. Nous concluons en commentant sur les possibles travaux futurs et sur un lien entre ce sujet et la physique des trous noirs.

Full textAbstract:
La transition vers les énergies renouvelables implique deux types de préoccupations environnementales. Les combustibles fossiles sont épuisables et leur utilisation génère des externalités négatives à travers des dommages environnementaux irréversibles. En outre, il existe des possibilités de synergies entre les mesures d'efficacité énergétique et l’adoption de l'énergie renouvelable dans la mesure où les premières réduisent la demande d'énergie de sorte que la dernière puisse commencer à réduire les émissions futures de gaz à effet de serre. L'objectif principal de cette thèse est d'analyser la transition énergétique optimale dans un contexte de survenance certaine et incertaine d'une catastrophe environnementale et de déterminer les instruments incitatifs au niveau des ménages en vue de stimuler la transition énergétique.La thèse est composée de quatre chapitres qui traitent indépendamment des différentes questions de la transition énergétique. Le premier chapitre met l'accent sur la transition énergétique optimale impliquant des décisions à la fois sur l'adoption de l'énergie renouvelable et de l'investissement dans les technologies d'économie d'énergie, quand il y a un seuil de pollution certain qui déclenche une catastrophe environnementale. Le deuxième chapitre étudie la transition optimale vers les énergies renouvelables quand la survenance de la catastrophe environnementale est incertaine. Le troisième chapitre cherche à comprendre le comportement des ménages par rapport à leurs décisions d'adopter simultanément les énergies renouvelables et à investir dans l'efficacité énergétique. Finalement, le quatrième chapitre examine le rôle des réseaux intelligents dans l'intégration de l'énergie renouvelable intermittente afin de faciliter la transition énergétiqueThe transition to renewable energy involves two kinds of environmental concerns. First, fossil fuels are exhaustible and second, their use generates negative externalities through irreversible environmental damage. Furthermore, there are possible synergies between energy efficiency measures and renewable energy adoption in the sense that the former reduces the energy demand so that the latter can begin to cut future greenhouse gases emissions. The main objective of this dissertation is to analyze the optimal energy transition under certain and uncertain occurrence of environmental catastrophe and to determine incentive-based instruments at the household level in order to boost the energy transition. The dissertation consists of four chapters that independently present and discuss different issues of energy transition. The first chapter focuses on the optimal energy transition involving decisions about both renewable energy adoption and investment in energy saving technologies, when there is a certain pollution threshold that triggers the occurrence of environmental catastrophe. The second chapter investigates the optimal transition to renewable energy under uncertain occurrence of environmental catastrophe. The third chapter is devoted to understanding household behavior regarding energy transition. The fourth chapter explores the role of smart-grids in integrating intermittent renewable energy to facilitate the energy transition

The purpose of this article is to reflect on homiletics and Christian preaching in the context of Latin America, in the current times of transition. In order to provide a better understanding of the approach, initially aspects of the Latin American religious and cultural context will be analyzed. Then there will be considerations on aspects of the
development of Christian preaching, creating a space to think about the relationship between Christian preaching and theologies that are relevant to the context, such as liberation theology. Finally a few challenges to Christian preaching in times of transition will be pointed out. Due to the delimitation of the article, it will focus on the homiletic development of the historical Protestant churches on the continent, above all in the Brazilian context.

Software handover is a de facto process in all software organizations. It is one of the most business critical and complex processes. It is also one of the most diverse processes, and thereby, one of the most difficult processes to define. Despite this, software handover is not well recognized within the academia. Right now, there are no software handover process models whatsoever although software organizations desperately need guidelines for how to perform this important and critical task. To aid them in defining their handover process models, we are in the process of creating Evolution and Maintenance Management Model (EM 3 ): Software Handover focusing on handover (alias transition) of a software system from developer to maintainer. In this paper, we evaluate one of the EM 3 components, Management and Administration (MA), addressing activities for planning and controlling the transition process, its schedule, budget and resources. We do it within 29 organizations. Our primary goal is to find out whether the component is realistic and whether it meets the needs and requirements of the software industry today. Using the feedback from the industry, we tackle process diversity using the C ontext- D riven P rocess Orchestration M ethod (CoDPOM).QC 20120223

En las páginas que siguen me he aproximado al desarrollo de las Comisiones Obreras durante la transición y la democracia. Más específicamente, mi investigación ha consistido en historizar la transformación experimentada desde su condición de movimiento sociopolítico de oposición a la dictadura, a la de central sindical confederal o, como ellos mismos teorizaron durante el período de cambio político, la construcción de un “sindicato de nuevo tipo”. En este sentido, han sido objeto de estudio tanto la estructuración y los combates de la central durante la transición como, más tarde, los debates estratégicos mantenidos - no siempre de forma cordial - y la acción sindical llevada a término durante las primeras legislaturas de gobiernos socialistas. Efectivamente, CCOO jugó un papel destacado en la crisis terminal del franquismo, sin embargo su prominente rol, aun en una nueva coyuntura marcada por el reflujo de la movilización social y la articulación de un marco democrático, continuó siendo relevante en el proceso de consolidación del nuevo régimen; cuestión que, sin embargo, la historiografía no ha recogido, a mi parecer, en su justa medida.
La historia que sigue, por lo tanto, es la de un actor sociopolítico de primer orden y, en este sentido, testigo fundamental de una época de importantes cambios. De alguna manera, podríamos decir que a la ruptura política con el régimen precedente, siguió también una ruptura en términos socioeconómicos (e incluso culturales), arena en la que este actor colectivo desplegaba su actividad. De la crisis de los años setenta – sinónimo de un paro obrero de larga duración- al proceso de “modernización” de los socialistas, España, siguiendo la estela de otros países europeos – aunque desde un punto de partida diferente – transitó del marco de un fordismo (autoritario), a una economía más integrada en el mercado europeo. Integración que, galvanizada por narrativas centradas en la competitividad, resultó concomitante a los procesos de flexibilización y desregulación del mercado laboral, así como de moderación salarial.
En un escenario adverso pero a la vez preñado de oportunidades, CCOO trató de consolidarse en términos orgánicos e institucionales, evitar los fenómenos de disgregación social y proponer sus alternativas concretas. Proceso de union-building y acción sindical que, lastrado por un desfase de al menos tres décadas, ofrece un balance de luces y sombras, pero que resulta, a su vez, relevante en aras de aprehender aquellos años de transición y consolidación democrática.In the following pages I have approached the development of the Workers' Commissions [CCOO] during the Transition from Franco regime and the democracy in Spain. Specifically, my object of study has been the transformation experienced from its status as a socio-political movement of opposition to the dictatorship, to that of a Confederal Trade Union or, as they themselves put it during the period of political change, the construction of a "new type of union." In this respect, both the structuring and struggle of the union during the transition have been studied. Likewise, I have paid attention to the strategic debates – not always cordially – and trade union action maintained during the first PSOE governments. Indeed, CCOO played a crucial role in the terminal crisis of the Francoist dictatorship, but its role remained relevant even in the new juncture marked by the ebb of social mobilization and the articulation of a democratic framework. However, in my opinion, historiography has not reflected this importance. The history that follows, therefore, is that of an important socio-political actor that, at the same time, was a fundamental witness of a period of important changes. Somehow, we could say that the political break with the previous regime was followed by a socio-economic (and even cultural) break. This was the environment in which the CCOO deployed its activity. As many other European countries – albeit from a different starting point –, Spain experienced very important changes between the crisis of the 1970s – synonymous of long-term unemployment – and the process of "modernization" of the 1980s and 1990s: the country moved from the framework of an authoritarian fordism to an economy integrated in the European market. This integration, stimulated by narratives focused on fostering competitiveness, was concomitant to the processes labor market deregulation and wage moderation. In a hard scenario – but at the same time loaded with opportunities –, CCOO sought to consolidate itself in organic and institutional terms, tried to avoid the social disintegration and proposed concrete alternatives. Although hampered by a lag of at least three decades, the process of union-building and the union action deployed offers a balance of lights and shadows. But, at the same time, is relevant to understand the years of Transition and democratic consolidation.

Full textAbstract:
La intenció fonamental d’aquesta tesi és fer un estudi de la Transició de l’Església espanyola i catalana i com va influir aquesta a la Transició política que es va fer posteriorment. També s’ha de considerar que la base de l’estudi és la jerarquia eclesiàstica, sobretot la catalana entre els anys 1970-1980.
Per començar, hi ha un breu resum biogràfic dels bisbes que regentaven les diferents diòcesis catalanes en els anys setanta, tot destacant el fet gairebé excepcional que tots eren de parla catalana i nascuts dins dels països catalans. A partir d’aquí es desenvolupa el tema que enclou des de l’Assemblea Conjunta fins el restabliment de la Generalitat i la seva problemàtica.
El fet d’iniciar el treball d’investigació per l’Assemblea Conjunta rau en que aquí podem situar el començament de la Transició Eclesial, on es tracten temes i polèmiques que mai havia abordat l’Església dins del franquisme; igualment, com es va organitzar a Catalunya, les seves problemàtiques i els resultats. A continuació s’estudia l’impacte del document “L’Església i la comunitat política”, de molta transcendència en les relacions Església – Estat. S’ha de tenir present que el document representa l’intent de la comunitat eclesial de separar-se del poder temporal, tant relacionats fins aleshores. De la mateixa manera s’analitzen les repercussions que va tenir pel govern franquista i els intents que es van fer per arribar a impedir els seus efectes. També es fa una anàlisi de les problemàtiques internes de l’Església, de la nova llei d’educació i com es rebuda per l’Església i el procés de catalanització de la comunitat eclesial a Catalunya.
La mort i posterior enterrament de Carrero Blanco va significar, per al poble en general, les males relacions entre els dirigents de l’Església i els de l’Estat, a part de que assenyalava el començament de la decadència del règim, cosa que la Conferència Episcopal tenia molt clara, i en conseqüència va prosseguir en el seus intents d’allunyar-se del poder polític. En referència al govern d’Arias Navarro, s’estudien dues qüestions, d’un banda, el cas Añoveros i de l’altre, el document sobre la reconciliació. El cas Añoveros va representar el moment de màxima tensió entre el govern i la jerarquia. S’aprofita l’ocasió per veure el ressò que va tenir a Catalunya, per la gran identificació d’un part important de l’Església catalana, amb la temàtica de la polèmica homilia del bisbe Añoveros. La reconciliació, temàtica central de l’Any Sant, va ser molt ben rebuda per la jerarquia perquè, feia temps que una part d’aquesta buscava l’entesa entre tots els espanyols, pensessin el que pensessin. Les reflexions no eren favorables al règim, però aquest ja no tenia la força suficient com per a parar les crítiques.
La mort de Franco va representar l’inici de la Transició Política. Els canvis que això suposava van ser ben rebuts per l’Església amb l’excepció de petits grups nostàlgics amb el passat. En aquest apartat s’estudien les repercussions de la Reforma Política, les primeres eleccions, la Constitució i les primeres lleis, la més polèmica la del divorci. L’Església, davant aquest allau de canvis, va intentar mantenir una neutralitat absoluta, no donant suport a cap grup polític, però sí que va donar les seves orientacions sobre els aspectes morals que havien de tenir en compte els fidels. Per acabar, s’analitza tot el procés de l’autonomia catalana, les seves conseqüències dins de l’Església catalana i les seves divergències amb l’espanyolaThe aim of this thesis is to study the transition period of the Spanish and Catalan Church and how it influenced the subsequent political transition. It is important to consider that the basis of this study is the ecclesiastic hierarchy, above all the Catalan hierarchy between the years 1970 and 1980. I start with a brief bibliographic summary of the bishops who held the different Catalan dioceses in the seventies, pointing out the exceptional fact that almost all of them spoke Catalan and were born in the Catalan Countries. After that, I develop the subject of the Joint Assembly (Assemblea Conjunta) and I explain the difficulties gone through to re-establish the Generalitat (the government of the autonomous community of Catalonia). I started my research work with the Joint Assembly, because it is there where we can say that the ecclesiastic transition started, since in this Assembly people dealt with subjects and controversies which had never been dealt with during the Franco period. I also explain how this Assembly was organised in Catalonia, its problems and its achievements. Next, I study the impact of the document “The Church and the Political Community”, which was very important in the relationship between the Church and the State. We have to take into account that the document represents the attempt of the ecclesiastic community to separate from the temporal political power, with which it had always been closely related. I also analyse the consequences that this transition had for the Franco government and the attempts carried out by this government to avoid its effects. In addition I do some research on the Church internal problems, the new education law and how the Church reacted to it, and the Catalanisation process in the ecclesiastic community of Catalonia. Carrero Blanco’s death and burial contributed to deteriorate the already bad relationship existing between Church and State leaders. Besides, it represented the beginning of the regime’s decline. The Episcopal Conference was well aware of this decline and therefore insisted on moving away from the political power. With reference to Arias Navarro’s government I deal with two subjects. On the one hand the Añoveros affair and on the other hand the reconciliation document. The Añoveros affair represented the highest tension moments between the government and the ecclesiastic hierarchy. This fact had a great impact in Catalonia where an important part of the Catalan Church agreed and felt identified with the subject of Añoveros’ polemic homily. The reconciliation, central subject of the Holy Year, was welcomed by the ecclesiastic hierarchy, because this one wanted all the Spanish people to come to an agreement, no matter what their ideas were. The thoughts and ideas discussed during the reconciliation process were ideas from people contrary to the political regime, but this one had no longer the strength to stop criticisms. Franco’s death and burial represented the start of the political transition. The changes that it brought about were welcomed by the Church, with the exception of some small nostalgic groups. In this part I comment the consequences of the political reform, the first elections, the Constitution (law), the first laws and among them the most polemic law: the divorce law. During all these changes, the Church was neutral and did not give support to any political parties, but it did give some advice and directions to the Catholic Christians about moral aspects. Finally, I analyse the process of the Catalan Autonomy, its consequences for the Catalan Church and the difference of opinions between the Catalan and the Spanish Church.

Full textAbstract:
The detection of exoplanets has rapidly evolved to one of the most important frontiers of astronomical and astrophysical research. The recent decades have seen the development of various techniques for detecting exoplanets. Of these approaches the transit method has received particular interest and has lead to the largest number of discoveries to date. The Kepler K2 mission is an ongoing observational survey, which has generated light curves for thousands of stars, a large fraction of which have yet to be fully explored. To discover and characterize the transiting planets hosted by the respective stars, extensive transit screens are required. However, implementing a pipeline for transit analyses is not straight forward, considering the light curve properties of different survey, the rapid changes brought by technological advancements, and the apparent lack of a golden standard with respect to the applied methodology. The project has reviewed several aspects of exoplanet detection via the transit method. Particular focus was placed on the identification of a suitable workflow covering the relevant steps to move from raw light curve files to a final prediction and characterization of transiting planetary candidates. Adhering to the identified strategy, the major part of the project then dealt with the implementation of a pipeline that integrates and executes all the different steps in a streamlined fashion. Of note, primary focus was placed on the actual selection and implementation of methods into an operational pipeline, but due to the given time constraints extensive optimizations of each individual processing step was outside the scope of this project. Nevertheless, the pipeline was employed to predict transit candidates for K2 campaigns C7, C8, C10, C11, and C12. A comparsion of the most conservative predictions from campaigns C7 and C10 with previously reported exoplanet candidates demonstrated that the pipeline was highly capable of discovering reliable transit candidates. Since campaigns C11 and C12 have not yet been fully explored, the respective candidates predicted for those campaigns in the current project might thus harbour novel planetary transit candidates that would be suitable for follow-up confirmation runs. In summary, the current project has produced a pipeline for performing transiting exoplanet searches in K2 data, which integrates the steps from raw light curve processing to transit candidate selection and characterization. The pipeline has been demonstrated to predict credible transit candidates, but future work will have to focus on additional optimizations of individual method parameters and on the analysis of transit detection efficiencies.

Dans cette these on definit de nouvelles classes de graphes sommet-transitifs dans lesquels il existe un routage de plus courtes chaines sommet-uniforme: les graphes quasi-cayley, les graphes a k-orbites regulieres. On etudie les proprietes de ces nouvelles classes, en particulier les proprietes algebriques de leurs groupes d'automorphismes. Un corollaire de cette etude est que la conjecture est vraie pour les graphes sommet-transitifs de diametre 2. On donne des exemples de familles de graphes quasi-cayley qui ne sont pas des graphes de cayley, des exemples de familles de graphes a k-orbites regulieres qui ne sont pas des graphes quasi-cayley. A cette occasion, on etudie la couverture par des cycles sommet-disjoints de l'ensemble des sommets de certains odd-graphs et de certains graphes de johnson ce qui permet d'introduire de nouvelles matrices combinatoires: les tableaux bordelais.

Vale, J. G. "The nature of the metal-insulator transition in 5d transition metal oxides." Thesis, University College London (University of London), 2017. http://discovery.ucl.ac.uk/1538695/.
Full textAbstract:
A number of 5d transition metal oxides (TMOs) either undergo, or lie proximate to, a metal-insulator transition (MIT). However these MITs frequently depart from a Mott-Hubbard picture, in which the interactions are dominated by the interplay between the on-site Coulomb repulsion and electronic bandwidth. In 5d TMOs the sizeable intrinsic spin-orbit coupling plays an important role, and gives rise to electronic and magnetic ground states -- at both sides of the MIT -- that cannot be adequately described within a purely L-S coupling scenario. In this thesis the aim is to understand the role of spin-orbit coupling in determining the electronic and magnetic properties of 5d TMOs. There has been a large amount of recent interest within this field (both experimentally and theoretically), however thus far has mostly been limited to the 5d5, j =1/2 limit. The perovskite iridates Sr2IrO4 and Sr3Ir2O7 lie within this limit. Theoretical predictions suggest a significant easy-plane anisotropy is present for the single layer Sr2IrO4. I show that this anisotropy can be observed and quantified, using magnetic critical scattering and previously published resonant inelastic X-ray scattering (RIXS) data. This differs from previous results that suggest purely 2D Heisenberg behaviour. Meanwhile the critical fluctuations in bilayer Sr3Ir2O7 have a three-dimensional nature, which can be directly related to the intra-bilayer coupling and significant anisotropy previously probed by RIXS. I also demonstrate that resonant X-ray scattering techniques can be successfully applied to other 5d systems, especially the d3 osmates. Both NaOsO3 and Cd2Os2O7 undergo MITs directly linked to the onset of antiferromagnetic order (Slater or Lifshitz mechanisms). The first ever high-resolution RIXS measurements at the Os L3 absorption edge reveal that there is a correlated evolution of the electronic and magnetic excitations through the respective MITs. The behaviour is consistent with a scenario in which the effect of spin-orbit coupling and electron correlations are reduced with respect to the iridates, yet still manifests through a strong spin wave anisotropy. Finally I show that the study of 5d TMOs can be extended into the time domain. Through the development of new instrumentation, the transient dynamics of photo-doped Sr2IrO4 were probed by time-resolved resonant (in)elastic X-ray scattering. The relevant time scales can be directly compared to the interaction strengths and anisotropies in the undoped state. Moreover, there seems to be an effective mapping of the transient behaviour in the photo-doped state to an equivalent level of bulk electron doping in (Sr_{1-x}La_x)2IrO4.

Full textAbstract:
Climate change has been recognised as one of the biggest challenges of our time. To prevent further climate change impacts, nations at COP21 further stressed the need to mitigate their greenhouse gas emissions enough to prevent dangerous temperature rise and to adapt societies to become more resilient. Municipals have been found important actors in this transition due to their power to inflict change on a local level. However, there is a lack of methods to assess how transition is made due to the fact that transition is a fairly new approach to managing climate change combined with a lack of completed transitions in municipalities. The purpose of this study is to explore the use of indicators as a method to assess municipal transition processes. Focusing on two Swedish municipalities that have been deemed vulnerable but at the same time apt to combat climate change, this study uses a triangulation of methods that are divided into two phases. The first phase uses a literature review in order to create a scientifically based list of transition indicators. The second phase uses document analyses and interviews in order to test the indicators and analyse transition process on a local level. The study revealed that there are multiple barriers and triggers for transition such as conflicting interests, economic factors, political steering, knowledge building- and awareness and long term perspectives, but that there also exist important tools for municipal transition in the form of networks through multi-level collaborations and plans/objectives. The findings in this study also suggests that the use of indicators as a method to assess transition could be viable, but that it is limited due to its contextual nature and lack of successful transitions to compare with.Klimatförändringar har ansetts vara en av de viktigaste utmaningarna i vår tid. För att förhindra att vidare skador av klimatförändringarna kom nationer som deltog i COP21 överens om att minska sina växthusgaser tillräckligt mycket för att förhindra farliga temperaturförhöjningar och att anpassa sina samhällen till resilienta enheter. Kommuner anses vara viktiga aktörer i denna omställning då de har makt att påverka förändringar på en lokal nivå. Dock saknas metoder för att bedöma hur omställning utförs då omställning är ett nytt angreppssätt kombinerat med en brist på genomförda omställningar. Syftet med denna uppsats är att utforska användningen av indikatorer som metod för att bedöma omställningsprocesser. Genom att använda en triangulering av metoder som delats upp i två faser fokuserar studien på två svenska kommuner som har fastställts som känsliga inför klimatförändringarna men även att ha förmågan att hantera dem. Den första fasen består av en litteraturstudie som skapade en vetenskaplig grund som berörde en global och nationell nivå. Den andra fasen bestod av en dokumentsanalys och intervjuer för att utforska omställningsprocesser på en lokal nivå. Studien visar på att det finns flera barriärer och drivkrafter för omställning som konkurrerande intressen, ekonomiska faktorer, politisk styrning, kunskaps byggande- och medvetenhet och långsiktighet men även att det fanns verktyg som var viktiga för kommunal omställning som nätverk genom samarbeten på olika nivåer och planer/mål. Slutligen visar även studien på att användningen av indikatorer som metod för att bedömma omställning skulle kunna vara möjligt men att begränsningar finns då metoden dels är kontextberoende men även att det är svårt att göra jämförelser då ingen fullförd omställning har skett.

Esta pesquisa investiga as sugestões da comunidade que possam contribuir com a redução dos acidentes de trânsito. Para isso foram questionadas quatrocentas pessoas no Estado de Santa Catarina, divididas em dois grupos de duzentas pessoas cada um. Analisa o comportamento, no momento de dirigir, entre pessoas que fazem parte da fiscalização do trânsito (autoridades) e das pessoas que somente utilizam as rodovias (usuários). Comparam as estratégias sugeridas para redução de acidentes, oriundas desses dois grupos e aponta as principais ações, aceitas pela comunidade, que possam auxiliar os governantes na resolução do problema.
