The persistence concern implemented as an aspect has been studied since the appearance of the Aspect-Oriented paradigm. Frequently, persistence is given as an example that can be aspectized, but until today no real world solution has applied that paradigm. Such solution should be able to enhance the programmer productivity and make the application less prone to errors. To test the viability of that concept, in a previous study we developed a prototype that implements Orthogonal Persistence as an aspect. This first version of the prototype was already fully functional with all Java types including arrays. In this work the results of our new research to overcome some limitations that we have identified on the data type abstraction and transparency in the prototype are presented. One of our goals was to avoid the Java standard idiom for genericity, based on casts, type tests and subtyping. Moreover, we also find the need to introduce some dynamic data type abilities. We consider that the Reflection is the solution to those issues. To achieve that, we have extended our prototype with a new static weaver that preprocesses the application source code in order to introduce changes to the normal behavior of the Java compiler with a new generated reflective code.

This thesis is in two parts: a creative work of fiction and a critical reflection on writing from an identity of expatriation. The creative work, a novel entitled Running on Rooftops, revolves around a fictitious community of expatriates living and working in China. As a new college graduate, Anne Henry, the novel’s protagonist and narrator, decides to spend a year teaching English in China. Twelve years later, though still unsure of how to make sense of the chain of events and encounters that left her with an X-shaped scar on her knee, she nevertheless tells the story, revealing how “just a year” can be anything but. The critical reflection, entitled Writing on Rooftops, explores the nature of expatriation as it relates to identity and writing, specifically in how West-meets-East encounters and attitudes are depicted in literature. In it, I examine the challenges and benefits of writing from an identity and mindset of expatriation as illustrated in the works of Western writers who themselves experienced and wrote from viewpoints of expatriation, particularly those Western writers who wrote of expatriation in China and Southeast Asia. The primary question addressed is how expatriation influences perception and how those perceptions among Western foreigners in China and Southeast Asia have been and can be reflected in literature. In the end, I argue that expatriation can be a valuable viewpoint to write from, offering new ways of seeing and describing our world, ourselves and the connections between the two.

This thesis aims to investigate the interaction of acoustic waves and fiber Bragg gratings (FBGs) in standard and suspended-core fibers (SCFs), to evaluate the influence of the fiber, grating and modulator design on the increase of the modulation efficiency, bandwidth and frequency. Initially, the frequency response and the resonant acoustic modes of a low frequency acousto-optic modulator (f < 1.2 MHz) are numerically investigated by using the finite element method. Later, the interaction of longitudinal acoustic waves and FBGs in SCFs is also numerically investigated. The fiber geometric parameters are varied and the strain and grating properties are simulated by means of the finite element method and the transfer matrix method. The study indicates that the air holes composing the SCF cause a significant reduction of the amount of silica in the fiber cross section increasing acousto-optic interaction in the core. Experimental modulation of the reflectivity of FBGs inscribed in two distinct SCFs indicates evidences of this increased interaction. Besides, a method to acoustically induce a dynamic phase-shift in a chirped FBG employing an optimized design of modulator is shown. Afterwards, a combination of this modulator and a FBG inscribed in a three air holes SCF is applied to mode-lock an ytterbium doped fiber laser. To improve the modulator design for future applications, two other distinct devices are investigated to increase the acousto-optic interaction, bandwidth and frequency (f > 10 MHz). A high reflectivity modulation has been achieved for a modulator based on a tapered fiber. Moreover, an increased modulated bandwidth (320 pm) has been obtained for a modulator based on interaction of a radial long period grating (RLPG) and a FBG inscribed in a standard fiber. In summary, the results show a considerable reduction of the grating/fiber length and the modulator size, indicating possibilities for compact and faster acousto-optic fiber devices. Additionally, the increased interaction efficiency, modulated bandwidth and frequency can be useful to shorten the pulse width of future all-fiber mode-locked fiber lasers, as well, to other photonic devices which require the control of the light in optical fibers by electrically tunable acoustic waves.

The objective of this study was to extend the use of combined longitudinal (P-wave) and shear (S-wave) ultrasonic wave reflection (UWR) to monitor the setting and stiffening of self-compacting pastes and concretes. An additional objective was to interpret the UWR responses of various modified cement pastes. A polymeric buffer with acoustic impedance close to that of cement paste, high impact polystyrene, was chosen to obtain sensitive results from the early hydration period. Criteria for initial and final set developed by our group in a prior study were used to compute setting times by UWR. UWR results were compared with standard penetration measurements. Stiffening behavior and setting times for normal cement pastes, pastes modified with mineral and chemical admixtures, self-compacting pastes, and concretes were explored using penetration resistance, S-wave and P-wave reflection. All three methods showed that set times of pastes varied linearly with w/c, that superplasticizer and fly ash delayed the set times of pastes, and that differences in w/cm, sp/cm, and fa/cm could be detected. Final set times determined from UWR correlated well with those from penetration resistance. Initial set times from S-wave reflection did not correlate very well with those from penetration resistance. Final set times from P-wave and S-wave reflection were roughly the same. Pastes with different chemical admixtures were tested, and the effects of these admixtures on stiffening were determined using UWR. Self-compacting concretes were studied using UWR, and their response and setting times were largely similar to that of corresponding self-compacting pastes. The P-wave reflection response was explored in detail, and the phenomenon of partial debonding and the factors affecting it were explained. Partial debonding is probably caused by autogenous shrinkage at final set, and was controlled and limited by water. The extent of partial debonding was higher with the transducers placed on the side as opposed to the bottom, and the S-wave transducer seemed to promote debonding in the P-wave reflection, whereas the P-wave transducer seemed to reduce debonding in the S-wave reflection. Simultaneous formwork pressure testing and UWR were performed; however, no clear correlation was seen between the two properties.

Discourse analysis as a methodology is perhaps not readily associated with substantive causality claims. At the same time the study of discourses is very much the study of conceptions of causal relations among a set, or sets, of agents. Within Europeanization research we have seen endeavours to develop discursive institutional analytical frameworks and something that comes close to the formulation of hypothesis on the effects of European Union (EU) policies and institutions on domestic change. Even if these efforts so far do not necessarily amount to substantive theories or claims of causality, it suggests that discourse analysis and the study of causality are by no means opposites. The study of Europeanization discourses may even be seen as an essential step in the move towards claims of causality in Europeanization research. This paper deals with the question of how we may move from the study of discursive causalities towards more substantive claims of causality between EU policy and institutional initiatives and domestic change.

Centrée essentiellement autour de la parole épiscopale congolaise, la présente recherche porte sur les articulations de la religion et du politique dans une perspective limitée au catholicisme en RDC. En prenant pour base empirique la ville de Kinshasa, elle thématise les effets des dynamiques religieuses sur les fermentations sociales et les changements politiques dans un contexte d’autoritarisme. Celui-ci est, dans ce travail, problématisé comme le fait conjoint de l’institution étatique et de l’organisation religieuse catholique. Le choix de cette approche relationnelle basée sur les interactions entre religion et politique, permet d’inscrire ce travail dans le champ d’études des sciences des religions. L’approche retenue s’appuie également sur les avancées de la sociologie politique et éclaire la régulation religieuse du politique, rarement étudiée par les sciences humaines. Cette recherche s’inscrit donc à l’intersection entre l’histoire, la sociologie, les sciences politiques, l’anthropologie, l’analyse du discours, la philosophie et la théologie. Sa thèse centrale est organisée autour d’une question principale : comment la religion participe-t-elle à la régulation du politique dans le contexte d’autoritarisme caractéristique de la RDC ? La réponse à cette question croise l’approche fonctionnelle de la religion et l’analyse des déclarations institutionnelles de l’épiscopat congolais. Elle esquisse les relations entre, d’une part, contextes et événements sociopolitiques et d’autre part, discours et pratiques religieuses. Elle construit la scène religieuse à partir de la trajectoire sociopolitique, économique et culturelle de la RDC entre 1990 et 2015, sous les Présidents J.-D. Mobutu, L.-D. Kabila et J. Kabila. Elle étudie l'offre normative de sens de leurs éminences J.-A. Malula, F. Etsou et L. Monsengwo. L’analyse de la rhétorique de l’épiscopat sur les élections vérifie la plausibilité sociale et l’efficience politique de la parole épiscopale congolaise. Elle se ressource dans la pragmatique de la communication telle que mise en œuvre dans l’analyse argumentative du discours de R. Amossy et dans celle du discours politique de P. Charaudeau. En mettant la focale sur l’objet linguistique « vérité des urnes », la recherche pose au niveau normatif, juridique et éthique, le problème de l’institutionnalisation d’un État de droit en RDC. Les élaborations sur ce dernier niveau s’articulent autour de l’inscription de l’éthique dans l’agir politique. L’examen des modes conventionnels d’action des chrétiens (élections de 2006 et 2011) et non conventionnels (marche des chrétiens de 1992 et 2012) conduit à éclairer les modes de reproduction ou de contestation de l’autoritarisme étatique par l’organisation religieuse. Il permet de promouvoir une démocratie des valeurs et d’action adossée à la parrhêsia. L’introduction de l’aléthique dans la vie publique donne à voir la parole épiscopale congolaise comme un discours ethopoïétique. C’est sur ce point précis que les élaborations de M. Foucault sur la parrhêsia aident à thématiser la capacité de la religion à informer et à influencer la démocratisation de la RDC. De là, la requête formulée pour un nouveau système d’action institutionnelle de l’organisation religieuse, susceptible de promouvoir le courage de la vérité en situation autoritaire. Cette innovation permet de tenir ensemble les valeurs démocratiques et les valeurs de l’Évangile, en les corrélant à la cohérence axiologique, à la probité morale et à l’intégrité existentielle des protagonistes de la démocratisation de la RDC.

Os contornos de um mundo em mudança e a evolução do pensamento há muito que se afastaram dos conceitos de identidades unas e imutáveis. A própria aceitação da mutabilidade traduz-se também nos cenários das vastas possibilidades para os fenómenos identitários à escala global. Também por isso, e mais do que nunca, se revela preponderante a reflexão sobre tais fenómenos identitários e a compreensão da sua intervenção e pertinência nas constantes reconfigurações sociais da atualidade. Esse será o universo do presente trabalho, onde serão auscultadas atuais conceções identitárias e o seu lugar no caso português. Este estudo configura-se, portanto, a partir de objetivos centrais bem delimitados: identificar e caracterizar a eventual existência de identidades regionais em Portugal, no caso particular dos territórios associados a Viseu. Este ponto de partida surge da análise da frequente cartografia das identidades territoriais na realidade portuguesa, bem como da continuidade de anteriores estudos do autor. Com efeito, verifica-se que frequentemente se definem duas grandes tipologias identitárias no que concerne à relação com o território: a local e a nacional. Tal posição surge em aberta contradição com os discursos mediáticos recorrentes onde a constante presença de um discurso de matriz regional obriga à dúvida inevitável. Nesse sentido, falando-se de região, foi necessário percorrer os conceitos de limite e de fronteira que a delimitam e lhe conferem sentido, indagando-se sobre o lugar da sua criação e da sua vivência. Assim, o trabalho orientou-se em dois grandes sentidos iniciais: o do levantamento da ação delimitadora do Estado, tido como autor das demarcações regionais em Portugal e o da auscultação da produção discursiva dos media regionais, agentes e expressão da identidade regional. A segunda dimensão obrigaria a um estudo aturado sobre a imprensa regional, objeto essencial do presente trabalho e a partir do qual será possível alcançar conclusões validáveis para o período entre 1959 e 2011. É então pelo cruzamento das duas dimensões referidas que se surpreende a existência de traços identitários regionais bem vincados, profundamente arreigados ao discurso do Estado Novo, raramente correspondendo aos intentos de delimitação das sucessivas iniciativas governamentais posteriores que, desse modo, revelam também um profundo distanciamento desse território que insistentemente vão dividindo. Entre o discurso eivado de simbolismo – embora centralista – do Estado Novo e as denominações técnicas – embora com o propósito de promover a descentralização do poder – da democracia, o discurso identitário da imprensa regional de Viseu alimenta-se ainda hoje do primeiro. Não porque vise os seus objetivos, mas porque é o que melhor caracteriza uma identidade relativamente pacificada: sempre pronta a recorrer ao passado beirão para afirmar as suas diferenças, sem no entanto pôr em causa o espírito da Nação; sempre pronta a denunciar o centralismo de Lisboa, esquecendo embora que foi esse centralismo que outrora lhe atribuiu a característica da genuinidade de, o que quer que seja, ser português.

Historically the imaginary and the hegemonic thinking, in the Western globe north, has been marked by the epistemology and capitalists archetypes. Notwithstanding the design seem as a practice and discipline shielded on a simplistic discourse of functional / communicative efficiency, wandering through by multiple aestheticism apparently neutral in relation to the symbolic, but in fact they never are, because what really hapens is that the aesthetic appearance of the generated forms will always be a review of the powers ruling. We start from the understanding that the act of creating an aesthetic artifact, will also be a movement of inscription in a discursive platform (that precedes it), is in itself an narrative act and that fact represent a certain take place in relation to certain symbolic reality. On reflection shown if it sees design as a discipline and / or an instrument of action, whose operational relevance tends to question and simultaneously rehearsing a response, in which more than why interests answer to why. Apparently the design is a content mediator, but also, it is structure, is body, is idea. We think a design praxis as discipline and enrollment tool of critical thought and social transformation. For guiding research in this text, we propose the following question: Can the Design want for themselves an engagement with the symbolic in order to be an active part in the production of critical thinking in the place where it belongs? Methodologically our argument will be present in two differents moments: 1. a first, exploratory nature where we rescue the draw issues in the practice of design and 2. a second analytical nature concerning the subject issues (graphic and / or utility ) design and how it incorporates formal rites, political events and social practices of contemporary everyday life. We consider the praxis of design as a discipline and critical thinking enrollment tool as agents of social transformation. With this study we seek for contribute phenomenology design by studying the artifacts of configuration as well as the possible messages they convey and what impact they may have on the social network.

The author carries out a pedagogical reflection on how the technology driven distance learning repeatedly neglects the scientific achievements of Second Language Acquisition and Language Pedagogy. Seeing communicative competence as a major goal of a language classroom, she presents the main challenges that the communicative approach poses to distance learning. To this end, a general distance learning theory by Moore is adapted to the needs of language education, through a distinction between three aspects of learner interaction – with the teacher, with other learners and with content. In this three-dimensional paradigm the learner is seen as the main actor of the process, the teacher as a facilitator, the text as a main source of communicative data and the learner autonomy as the fundament of the process.

This dissertation is the result of an ethnographic journey undertaken in three spiritual centers of Umbanda , located in different districts of Natal/RN. The aim of the study was to understand how the representations of exus (spirit category) are established in the studied religious environment. In order to study this, mythical narratives of songs and of people were analyzed. In addition, the incorporated spirit entities, loaded with codes and values, were possible to be read and understood. The present work was developed according to a theoretical and methodological approach that interprets culture as a constant construction process, with representations and significations. The empirical research focuses on the ethnographic observations and the narratives; providing the experimentation of the models of discursive dialogues and polyphony. It was observed that the studied empirical field is marked by the cult of the Jurema which influences the mythical construction of exus . Therefore, this study enabled a reflection on the meeting of notions of two distinct worlds ( Umbanda and Jurema ). This reflection is crucial to the understanding of the position that exus occupy in the local umbandista system

This thesis considers the impact that discursive and community practices have on women’s access to the public sphere by examining female cyclists and a cycling community in Miami, Florida via interviews and observation. In the interviews, female cyclists frequently reported fears for their safety, including concern over harassment, when riding in public space. I interviewed participants of the cycling community and observed Emerge Miami’s meetings and events, where publicly organized cycling excursions were a major component. Using the theoretical and methodological lenses of Feminist Critical Discourse Analysis and Communities of Practice, I examined the interviews to understand how participants discursively framed and contextualized gender-based harassment. I found two meta-discourse frames in operation: a normative frame (that essentially accepted the status quo) and a feminist frame (that challenged the “naturalness” of women’s harassment as just what one had to live with). The feminist frame offered a pathway for women to exert control over their experiences and alter the cultural understanding of harassment’s meaning and effect. The local community practices of Emerge Miami also challenged the normative frames that often silence women, employing explicitly invitational practices, which demonstrates how local discursive and social activity can impact and increase women’s involvement by creating a more accessible space for women to engage with their local cycling community.

This dissertation examined the formation of Japanese identity politics after World War II. Since World War II, Japan has had to deal with a contradictory image of its national self. On the one hand, as a nation responsible for colonizing fellow Asian countries in the 1930s and 1940s, Japan has struggled with an image/identity as a regional aggressor. On the other hand, having faced the harsh realities of defeat after the war, Japan has seen itself depicted as a victim. By employing the technique of discourse analysis as a way to study identity formation through official foreign policy documents and news media narratives, this study reconceptualized Japanese foreign policy as a set of discursive practices that attempt to produce renewed images of Japan’s national self. The dissertation employed case studies to analyze two key sites of Japanese postwar identity formation: (1) the case of Okinawa, an island/territory integral to postwar relations between Japan and the United States and marked by a series of US military rapes of native Okinawan girls; and (2) the case of comfort women in Japan and East Asia, which has led to Japan being blamed for its wartime sexual enslavement of Asian women. These case studies found that it was through coping with the haunting ghost of its wartime past that Japan sought to produce “postwar Japan” as an identity distinct from “wartime imperial Japan” or from “defeated, emasculated Japan” and, thus, hoped to emerge as a “reborn” moral and pacifist nation. The research showed that Japan struggled to invent a new self in a way that mobilized gendered dichotomies and, furthermore, created “others” who were not just spatially located (the United States, Asian neighboring nations) but also temporally marked (“old Japan”). The dissertation concluded that Japanese foreign policy is an ongoing struggle to define the Japanese national self vis-à-vis both spatial and historical “others,” and that, consequently, postwar Japan has always been haunted by its past self, no matter how much Japan’s foreign policy discourses were trying to make this past self into a distant or forgotten other.

This book brings together the fields of language policy and discourse studies from a multidisciplinary theoretical, methodological and empirical perspective. The chapters in this volume are written by international scholars active in the field of language policy and planning and discourse studies. The diverse research contexts range from education in Paraguay and Luxembourg via businesses in Wales to regional English language policies in Tajikistan. Readers are thereby invited to think critically about the mutual relationship between language policy and discourse in a range of social, political, economic and cultural spheres. Using approaches that draw on discourse-analytic, anthropological, ethnographic and critical sociolinguistic frameworks, the contributors in this collection explore and refine the ‘discursive’ and the ‘critical’ aspects of language policy as a multilayered, fluid, ideological, discursive and social process that can operate as a tool of social change as well as reinforcing established power structures and inequalities.
