Photo luminescence: A probe for short, medium and long-range self-organization order in ZrTiO4 oxide

Photoluminescent disordered ZrTiO4 powders were obtained by the polymeric precursor soft-chemical method. This oxide system (ordered and disordered) was characterized by photoluminescence, Raman spectroscopy, X-ray diffraction, differential scanning calorimetry and UV vis absorption experiments. The UV absorption tail formation in the disordered oxides was related to the diminution of optical band gap. In the disordered phase, this oxide displayed broad band photoluminescence caused by change in coordination number of titanium and zirconium with oxygen atoms. The gap decreased from 3.09 eV in crystalline oxide to 2.16 eV in disordered oxide. The crystalline oxide presented an orthorhombic alpha-PbO2-type structure in which Zr4+ and Ti4+ were randomly distributed in octahedral coordination polyhedra with oxygen atoms. The amorphous-crystalline transition occurred at almost 700 degrees C, at which point the photoluminescence vanished. The Raman peak at close to 80-200 cm(-1) indicated the presence of locally ordered Ti-O-n and Zr-O-n polyhedra in disordered photoluminescent oxides. (c) 2006 Elsevier B.V. All rights reserved.

Woodrow Wilson's ''Rhetorical restructuring'': The transformation of the American self and the construction of the German enemy

From a comprehensive study of the public addresses of Woodrow Wilson in the period following the outbreak of the war in Europe in August 1914 to the war's conclusion in June 1919, this essay examines Wilson's transformation of the long-held vision of America as merely a great example of liberty to its embodiment as the self-sacrificing champion of liberty. It will demonstrate how this transformation of the American "self" was inextricably connected to a changing image of the war and the construction of an enemy image of the German government.

Navigating the Self in Diverse Work Contexts

Navigating the self is critical for working in a diverse world, in which different identities interact in social space. This chapter presents five theoretical perspectives on how individuals navigate the self in diverse organizational contexts—social identity, critical identity, (role) identity, narrative-as-identity, and identity work. We review these five prominent theoretical perspectives on identity processes in diverse contexts to explicate various ways in which individuals actively participate in the co-construction of their identities in diverse contexts. As a next step in research, identity, diversity, and relationship scholars are encouraged to inquire into the generativity of proposed tactics for navigating the self in order to identify pathways for cultivating more positive identities in diverse work settings. The examination of positive relational identities is considered a promising path for further inquiry in this domain.

Processo de transição da pessoa estomizada da depêndencia de cuidado ao autocuidado: subsídios à enfermagem

Objetivou-se conhecer como a pessoa com estomia vivência o processo de transição da dependência de cuidados ao autocuidado à luz da Teoria das Transições de Meleis. Pesquisa exploratória, descritiva com abordagem qualitativa no Serviço de Estomaterapia do Hospital Universitário Dr Miguel Riet Corrêa Jr do Rio Grande/ RS/ Brasil com 27 pessoas com estomias definitivas por câncer. Os dados foram coletados nos mês de janeiro e fevereiro de 2014 por meio de entrevista com roteiro semiestruturado e submetidos à Análise de Conteúdo apoiada nas ideias da Teoria das Transições de Afaf I. Meleis. Constatou-se que a natureza da transição situou-se no processo tipo saúde/doença. A entrada no processo de transição deu-se a partir da consciência desencadeada pelo diagnóstico de câncer, reforçado pela cirurgia de estomização. O empenhamento surge ao dedicarem-se a construção do conhecimento para o autocuidado frente às mudanças na sua vida e na sua nova relação com seu corpo, mudando a visão de si, do mundo e dos outros. Destacou-se o espaço temporal como algo dinâmico e variavelmente indeterminável, sendo fundamental para que se organizem e reflitam acerca do seu novo viver, fortalecendo-se para que a transição progrida. Verificaram-se como fatores facilitadores do autocuidado a construção de um significado positivo à estomização, o preparo dessa experiência ainda no pré-operatório, a estabilidade emocional, a fé e a religiosidade e a sensação de normalidade adquirida a partir de uma imagem próxima da anterior. Referiram-se, ainda, ao fornecimento de forma gratuita pelo governo das bolsas coletoras, adjuvantes e acessórios e ao atendimento da equipe multiprofissional. Como fatores inibidores do processo de transição encontraram-se a visão distorcida de seu corpo, o despreparo para viver com a estomia, a instabilidade emocional, a desmotivação com afastamento de atividades prazerosas, o cuidado excessivo e/ou estendido e até mesmo a superproteção da família, as complicações como hérnias e prolapsos, a falta de atitudes positivas quanto à vida, a negação da bolsa coletora, as tentativas frustradas de omitir o uso da bolsa coletora, a falta do domínio do manuseio dos equipamentos, o afastamento do trabalho e as dificuldades financeiras. Além destas, o abandono do parceiro, atitudes negativas e estigmatizantes por parte da família e a baixa qualidade dos materiais fornecidos pelo governo. Como indicadores de resultados identificaram-se a confiança para realizar atividades anteriores, aceitação de sua situação, uma visão positiva de sua vida e da capacidade de compartilhar o seu cuidado com sua família. Considera-se a saída da transição quando este for capaz de dominar novas competências tanto para o cuidado físico ao realizar a troca da bolsa coletora quanto readequando sua imagem e autoconceito. Concluiu-se que o processo de transição da dependência de cuidados ao autocuidado da pessoa com estomia é complexo e carregado de subjetividades. É necessário que o enfermeiro estabeleça ações terapêuticas de enfermagem eficazes e eficientes, contribuindo para a promoção e reabilitação da saúde deste, auxiliando-o na aquisição de sua autonomia e independência, subsidiando seu autocuidado e bem-estar.

De l’applicabilité du droit international des droits de l’homme dans l’ordre juridique interne

De nos jours, les particuliers peuvent se prévaloir, devant les autorités judiciaires nationales, du droit international des droits de l’homme d’origine conventionnelle, à condition qu’il soit admis que celui-ci est partie intégrante du droit positif national. Les conventions internationales de sauvegarde des droits fondamentaux imprègnent l’ordre juridique interne soit par le biais de compléments internes d’ordre législatif ou réglementaire (logique dualiste), soit du seul fait de leur ratification suivie de leur publication officielle (logique moniste). En l’absence d’une réglementation internationale uniforme des critères de l’applicabilité directe, la difficulté d’identifier les traités de protection des droits de l’homme directement applicables dans l’ordre interne demeure réelle, notamment dans les Etats qui adhèrent à la conception moniste de l’ordre juridique. De façon décisive, la doctrine et la jurisprudence ont consacré deux critères d’identification des clauses conventionnelles autoexécutoires (self-executing), à savoir le critère subjectif du destinataire de la norme internationale et le critère objectif du degré de normativité juridique de celle-ci. La difficulté de la tâche n’en est pas pour autant annihilée comme en atteste, dans le cadre de l’affaire Hissène Habré, la vive controverse sur le caractère prétendument self-executing de la Convention contre la torture. 

Històries de malaltia : anàlisi narrativa en l'experiència de càncer

En la present tesi doctoral es presenta, des d'una perspectiva narrativa i socioconstruccionista, una aproximació a l'estudi de l'experiència de malaltia en càncer a partir del treball amb relats narrats. Es realitza una anàlisi narrativa de la construcció de les històries de malaltia a partir dels relats escrits per les persones "malaltes" i /o els seus familiars. Es cerquen elements per a la reflexió de: a) el paper de la narració en la comprensió de l'experiència de malaltia oncològica i la construcció narrativa d'identitat; b) l'ús del mètode d'anàlisi narrativa dins el camp de la salut/malaltia; i c) implicacions i aplicacions en la pràctica terapèutica. Seguint una orientació metodològica qualitativa, s'analitza la construcció de narratives de malaltia i del self, la construcció i relació amb els personatges de la història, la construcció de la malaltia (càncer), així com les potencialitats i limitacions de l'aproximació narrativa en l'estudi. Finalment, es presenten elements narratius per a la reflexió del seu ús en l'atenció psicològica i la pràctica del professional de la salut en càncer.

E.1027. Maison en bord de mer: Theoretical Restoration

E.1027, Maison en bord de mer is a small villa in Roquebrune Cap-Martin, built by architects Eileen Gray and Jean Badovici between 1926 and 1929. It was hailed as a landmark of modern architecture, and then forgotten. Over the years many transformations have been carried out, and these changes have altered the spatial qualities of the original project. Time and neglect have taken their toll, and until 2008 the villa was abandoned, a shadow of its former self. In order to state an appropriate restoration, a description of the house and its historic evolution has been made, comparing plans of its different transformations. After compiling the most common pathologies and restoration procedures in buildings of the Modern Movement in general, the particular pathologies of E.1027 are presented, concluding with a restoration proposal for E.1027 that considers aesthetical as well as technical aspects. This study involves an attempt to establish guidelines for the theoretical and technical aspects for restoration of architecture of the Modern Movement, using the Maison en bord de mer as an example.

Mundos prohibidos: El poder en el discurso epistolar de Gertrudis Gómez de Avellaneda y Juana Borrero

This dissertation analyses, through a theoretical framework and a critical approach, letters of Cuban writers Gertrudis Gómez de Avellaneda and Juana Borrero. While love letters have captured the interest of some scholars, such as Claudio Guillén, Cintio Vitier and Alexander Roselló Selimov, the conflict that the analysis of non-literary texts poses has prevented further research in this field. Therefore, I propose a systematic method of analysis encompassing but not limited to evaluating letters based on their purpose, intent, interpretation, and temporal and spatial composition; analyzing the perspective and function of epistolary entities, and examining the textual signs that distinguish the epistolary forms from the literary forms. With this analytical tool, I examine a selection of letters of Gómez de Avellaneda and demonstrate that the writer displaces her identify from the autobiographic self to the epistolary self, in order to manipulate the perspective of her addressee. Caught between the Neoclassical way of thinking and the Romantic aesthetics, her assertive discourse, also reflected in her epistolary work, contributed to the incursion of women writers into the social and professional life of the nineteen century. Following the same method of investigation, an analysis of letters written by Borrero proves that, by building a world of delusion, hallucination and fantasy the writer brings to prose what first generation of female modernistas had done in poetry. In both cases, my focus is on the strategies that turn these letters into instruments of power, process that transformed the love-letter paradigm and forever renovated the women epistolary genre. This dissertation further explores the possibility of initiating a cycle in the study of personal letters to uncover a forgotten genre, mission that might build a bridge to embrace the new forms of written communication that scholars have already begun to explore in contemporary literature.

Lieu de liens, lieu de vie : oser le réseau comme alternative à la vulnérabilité : le cas des demandeurs d’asile à Projet Refuge (Montréal).

La vulnérabilité est l’attribut fondamental justifiant le passage des frontières du refuge canadien (Rousseau et al., 2002 ; Clément et Bolduc, 2004). Elle est preuve d’insécurité pour la victime requérant l’asile ; elle est aussi porteuse d’espérance de sécurité en terre hospitalière. Elle est pourtant potentiel réactualisé dans l’insécurité d’un statut incertain en terre d’accueil (Agamben, 1997 ; D’Halluin, 2004). Violente immersion. En attendant que les preuves de sa vulnérabilité originelle soient validées, le demandeur d’asile se retrouve dans un entre-deux a-territorial et atemporel (Agier, 2002 ; Le Blanc, 2010) et dans une précarité tout aussi dangereuse (Ouimet et al., 2009). Des besoins émergent en cette terre inconnue, or l’accès aux soins de santé lui est limité par des textes de lois ambigus et leurs interprétations maladroites (Harris et Zuberi, 2015). Ainsi lorsqu’il se heurte à des barrières érigées par une transmission d’informations défectueuse, sa précarité ne fait qu’empirer. Tel un boomerang, ce paradoxe cultive leur vulnérabilité. Alors que les recherches interrogent les divers intervenants en santé (Asgary et Smith, 2013), j’ai choisi de donner la parole aux premiers concernés et de relayer leur vécu par rapport à leur propre personne. Deux objectifs principaux guident la recherche : documenter dans un premier temps leur parcours de quête de soins à partir de la circulation des informations formelles et informelles dans le but de sonder leur avis sur la vulnérabilité qui leur est attribuée ; documenter dans un second temps leur parcours migratoire de quête de soi afin de mettre en lumière les stratégies alternatives d’entrée en contact avec la société d’accueil pour négocier voire rejeter cette identité vulnérable. J’ai rencontré pour cela des demandeurs d’asile lors d’un terrain de huit mois au sein d’un organisme communautaire d’hébergement à Montréal. Dans ce contexte d’accompagnement et de stabilité spatiale, accalmie bienvenue au terme d’un itinéraire semé d’embûches, les ressources informationnelles sont à leur disposition et la reconnaissance sociale est à l’honneur. En parallèle, beaucoup témoignent de la diminution de leurs besoins de soins de santé. En cette communauté thérapeutique (Pocreau, 2005), véritable tremplin vers la société d’accueil en attendant un statut reconnu, ils bénéficient d’une possibilité de participation sociale et d’un sentiment d’appartenance valorisant. Si des conditions précaires peuvent aggraver la vulnérabilité, le bricolage de conditions positives favorise la résilience (Cleveland et al., 2014), créant un environnement revitalisant qui leur permet de rebondir.

Self construction, cognitive conflicts and polarization in bulimia nervosa

This study explores the cognitive structures, understood as construct systems, of patients suffering from bulimia nervosa (BN). Previous studies investigated the construct systems of disordered eaters suggesting that they had a higher distance between their construction of the self and the «ideal self», and also more rigidity. In addition to these aspects, this study explored the presence of implicative dilemmas (ID). Thirty two women who met criteria for BN and were treated in a specialized center were compared to a non clinical group composed by 32 women matched by age. All participants were assessed using Repertory Grid Technique (RGT). In BN patients it was more common (71.9%) to find IDs than in controls (18.8%). They also showed higher polarization and higher self-ideal discrepancies (even more for those with a long history of BN). The measures provided by the RGT can be useful for the assessment of self-construction and cognitive conflicts in BN patients and to appreciate their role in this disorder. In addition, this technique could be helpful for clinicians to explore the patient"s constructs system, and specially to identify IDs that could be maintaining the symptoms or hindering change in order to focus on them to facilitate improvement.

The automatic layout model in the sequencing of construction activities of multi-objective diaphragm wall unit by using self-learning neural network

Foundation construction process has been an important key point in a successful construction engineering. The frequency of using diaphragm wall construction method among many deep excavation construction methods in Taiwan is the highest in the world. The traditional view of managing diaphragm wall unit in the sequencing of construction activities is to establish each phase of the sequencing of construction activities by heuristics. However, it conflicts final phase of engineering construction with unit construction and effects planning construction time. In order to avoid this kind of situation, we use management of science in the study of diaphragm wall unit construction to formulate multi-objective combinational optimization problem. Because the characteristic (belong to NP-Complete problem) of problem mathematic model is multi-objective and combining explosive, it is advised that using the 2-type Self-Learning Neural Network (SLNN) to solve the N=12, 24, 36 of diaphragm wall unit in the sequencing of construction activities program problem. In order to compare the liability of the results, this study will use random researching method in comparison with the SLNN. It is found that the testing result of SLNN is superior to random researching method in whether solution-quality or Solving-efficiency.

Pensamos que somos historia porque sabemos que somos historia: context, self and self-construction in women's testimonial writing from revolutionary Cuba

This article presents a group of women-authored testimonial texts published between 1959–1989 in revolutionary Cuba. Despite the recent scholarly debates within Latin American Cultural Studies regarding Latin American testimonio, these texts have received little or no critical or theoretical attention within or outside Cuba. The article therefore starts by situating them within the specific context of revolutionary culture, especially with reference to questions of gender, genre and publication. Having established that the texts as a whole privilege the collective revolutionary context and revolutionary experience over gendered or generic aspects, the seven texts are then grouped under a more specific contextual category, as narratives of voluntary work (participation and observation), in order to provide a clearer structure for their description and analysis. Each of the texts is then described within its sub-group, and the article ends by indicating how such texts challenge testimonio paradigms by positing a relational notion of subjectivity.
