A Comparative Analysis of Hedging in a Corpus of Two Written Legal Discourse Genres

Esta tesis doctoral, que es la culminación de mis estudios de doctorado impartidos por el Departamento de Lingüística Aplicada a la Ciencia y a la Tecnología de la Universidad Politécnica de Madrid, aborda el análisis del uso de la matización (hedging) en el lenguaje legal inglés siguiendo los postulados y principios de la análisis crítica de género (Bhatia, 2004) y empleando las herramientas de análisis de córpora WordSmith Tools versión 6 (Scott, 2014). Como refleja el título, el estudio se centra en la descripción y en el análisis contrastivo de las variedades léxico-sintácticas de los matizadores del discurso (hedges) y las estrategias discursivas que con ellos se llevan a cabo, además de las funciones que éstas desempeñan en un corpus de sentencias del Tribunal Supremo de EE. UU., y de artículos jurídicos de investigación americanos, relacionando, en la medida posible, éstas con los rasgos determinantes de los dos géneros, desde una perspectiva socio-cognitiva. El elemento innovador que ofrece es que, a pesar de los numerosos estudios que se han podido realizar sobre los matizadores del discurso en el inglés general (Lakoff, 1973; Hübler, 1983; Clemen, 1997; Markkanen and Schröder, 1997; Mauranen, 1997; Fetzer 2010; y Finnegan, 2010 entre otros) académico (Crompton, 1997; Meyer, 1997; Skelton, 1997; Martín Butragueňo, 2003) científico (Hyland, 1996a, 1996c, 1998c, 2007; Grabe and Kaplan, 1997; Salager-Meyer, 1997 Varttala, 2001) médico (Prince, 1982; Salager-Meyer, 1994; Skelton, 1997), y, en menor medida el inglés legal (Toska, 2012), no existe ningún tipo de investigación que vincule los distintos usos de la matización a las características genéricas de las comunicaciones profesionales. Dentro del lenguaje legal, la matización confirma su dependencia tanto de las expectativas a macro-nivel de la comunidad de discurso, como de las intenciones a micro-nivel del escritor de la comunicación, variando en función de los propósitos comunicativos del género ya sean éstos educativos, pedagógicos, interpersonales u operativos. El estudio pone de relieve el uso predominante de los verbos modales epistémicos y de los verbos léxicos como matizadores del discurso, estos últimos divididos en cuatro tipos (Hyland 1998c; Palmer 1986, 1990, 2001) especulativos, citativos, deductivos y sensoriales. La realización léxico-sintáctica del matizador puede señalar una de cuatro estrategias discursivas particulares (Namsaraev, 1997; Salager-Meyer, 1994), la indeterminación, la despersonalización, la subjectivisación, o la matización camuflada (camouflage hedging), cuya incidencia y función varia según género. La identificación y cuantificación de los distintos matizadores y estrategias empleados en los diferentes géneros del discurso legal puede tener implicaciones pedagógicos para los estudiantes de derecho no nativos que tienen que demostrar una competencia adecuada en su uso y procesamiento. ABSTRACT This doctoral thesis, which represents the culmination of my doctoral studies undertaken in the Department of Linguistics Applied to Science and Technology of the Universidad Politécnica de Madrid, focusses on the analysis of hedging in legal English following the principles of Critical Genre Analysis (Bhatia, 2004), and using WordSmith Tools version 6 (Scott, 2014) corpus analysis tools. As the title suggests, this study centers on the description and contrastive analysis of lexico-grammatical realizations of hedges and the discourse strategies which they can indicate, as well as the functions they can carry out, in a corpus of U.S. Supreme Court opinions and American law review articles. The study relates realization, incidence and function of hedging to the predominant generic characteristics of the two genres from a socio-cognitive perspective. While there have been numerous studies on hedging in general English (Lakoff, 1973; Hübler, 1983; Clemen, 1997; Markkanen and Schröder, 1997; Mauranen, 1997; Fetzer 2010; and Finnegan, 2010 among others) academic English (Crompton, 1997; Meyer, 1997; Skelton, 1997; Martín Butragueňo, 2003) scientific English (Hyland, 1996a, 1996c, 1998c, 2007; Grabe and Kaplan, 1997; Salager-Meyer, 1997 Varttala, 2001) medical English (Prince, 1982; Salager-Meyer, 1994; Skelton, 1997), and, to a lesser degree, legal English (Toska, 2012), this study is innovative in that it links the different realizations and functions of hedging to the generic characteristics of a particular professional communication. Within legal English, hedging has been found to depend on not only the macro-level expectations of the discourse community for a specific genre, but also on the micro-level intentions of the author of a communication, varying according to the educational, pedagogical, interpersonal or operative purposes the genre may have. The study highlights the predominance of epistemic modal verbs and lexical verbs as hedges, dividing the latter into four types (Hyland, 1998c; Palmer, 1986, 1990, 2001): speculative, quotative, deductive and sensorial. Lexical-grammatical realizations of hedges can signal one of four discourse strategies (Namsaraev, 1997; Salager-Meyer, 1994), indetermination, depersonalization, subjectivization and camouflage hedging, as well as fulfill a variety of functions. The identification and quantification of the different hedges and hedging strategies and functions in the two genres may have pedagogical implications for non-native law students who must demonstrate adequate competence in the production and interpretation of hedged discourse.

Un estudio del adjetivo en un corpus de textos escritos en inglés y español pertenecientes al discurso de especialidad de las Tecnologías de la Información y las Comunicaciones

Esta investigación se enmarca dentro de los denominados lenguajes de especialidad que para esta tesis será el de las Tecnologías de la Información y la Comunicación (TIC). De todos los aspectos relacionados con el estudio de estos lenguajes que pudieran tener interés lingüístico ha primado el análisis del componente terminológico. Tradicionalmente la conceptualización de un campo del saber se representaba mayoritariamente a través del elemento nominal, así lo defiende la Teoría General de la Terminología (Wüster, 1968). Tanto la lexicología como la lexicografía han aportado importantes contribuciones a los estudios terminológicos para la identificación del componente léxico a través del cual se transmite la información especializada. No obstante esos primeros estudios terminológicos que apuntaban al sustantivo como elmentos denominativo-conceptual, otras teorías más recientes, entre las que destacamos la Teoría Comunicativa de la Terminología (Cabré, 1999) identifican otras estructuras morfosintácticas integradas por otros elementos no nominales portadores igualmente de esa carga conceptual. A partir de esta consideración, hemos seleccionado para este estudio el adjetivo relacional en tanto que representa otra categoría gramatical distinta al sustantivo y mantiene un vínculo con éste debido a su procedencia. Todo lo cual puede suscitar cierto interés terminológico. A través de esta investigación, nos hemos propuesto demostrar las siguientes hipótesis: 1. El adjetivo relacional aporta contenido especializado en su asociación con el componente nominal. 2. El adjetivo relacional es portador de un valor semántico que hace posible identificar con más precisión la relación conceptual de los elementos -adjetivo y sustantivo - de la combinación léxica resultante, especialmente en algunas formaciones ambiguas. 3. El adjetivo relacional, como modificador natural del sustantivo al que acompaña, podría imponer cierta restricción en sus combinaciones y, por tanto, hacer una selección discriminada de los integrantes de la combinación léxica especializada. Teniendo en cuenta las anteriores hipótesis, esta investigación ha delimitado y caracterizado el segmento léxico objeto de estudio: la ‘combinación léxica especializada (CLE)’ formalmente representada por la estructura sintáctica [adjR+n], en donde adjR es el adjetivo y n el sustantivo al que acompaña. De igual forma hemos descrito el marco teórico desde el que abordar nuestro análisis. Se trata de la teoría del Lexicón Generatvio (LG) y de la representación semántica (Pustojovsky, 1995) que propone como explicación de la generación de significados. Hemos analizado las distintas estructuras de representación léxica y en especial la estructura qualia a través de la cual hemos identificado la relación semántica que mantienen los dos ítems léxicos [adjR+n] de la estructura sintáctica de nuestro estudio. El estudio semántico de las dos piezas léxicas ha permitido, además, comprobar el valor denominativo del adjetivo en la combinación. Ha sido necesario elaborar un corpus de textos escritos en inglés y español pertenecientes al discurso de especialidad de las TIC. Este material ha sido procesado para nuestros fines utilizando distintas herramientas electrónicas. Se ha hecho uso de lexicones electrónicos, diccionarios online generales y de especialidad y corpus de referencia online, estos últimos para poder eventualmente validad nuetros datos. Asimismo se han utilizado motores de búsqueda, entre ellos WordNet Search 3.1, para obtener la información semántica de nuestros elementos léxicos. Nuestras conclusiones han corroborado las hipótesis que se planteaban en esta tesis, en especial la referente al valor denominativo-conceptual del adjetivo relacional el cual, junto con el sustantivo al que acompaña, forma parte de la representación cognitiva del lenguaje de especialidad de las TIC. Como continuación a este estudio se proponen sugerencias sobre líneas futuras de investigación así como el diseño de herramientas informáticas que pudieran incorporar estos datos semánticos como complemento de los ítems léxicos dotados de valor denominativo-conceptual. ABSTRACT This research falls within the field of the so-called Specialized Languages which for the purpose of this study is the Information and Communication Technology (ICT) discourse. Considering their several distinguishing features terminology concentrates our interest from the point of view of linguistics. It is broadly assumed that terms represent concepts of a subject field. For the classical view of terminology (Wüster, 1968) these terms are formally represented by nouns. Both lexicology and terminology have made significant contributions to the study of terms. Later research as well as other theories on Terminology such as the Communicative Theory of Terminology (Cabré, 1993) have shown that other lexical units can also represent knowledge organization. On these bases, we have focused our research on the relational adjective which represents a functional unit different from a noun while still connected to the noun by means of its nominal root. This may have a potential terminological interest. Therefore the present research is based on the next hypotheses: 1. The relational adjective conveys specialized information when combined with the noun. 2. The relational adjective has a semantic meaning which helps understand the conceptual relationship between the adjective and the noun being modified and disambiguate certain senses of the resulting lexical combination. 3. The relational adjective may impose some restrictions when choosing the nouns it modifies. Considering the above hypotheses, this study has identified and described a multi-word lexical unit pattern [Radj+n] referred to as a Specialized Lexical Combination (SLC) linguistically realized by a relational adjective, Radj, and a noun, n. The analysis of such a syntactic pattern is addressed from the framework of the Generative Lexicon (Pustojovsky, 1995). Such theory provides several levels of semantic description which help lexical decomposition performed generatively. These levels of semantic representation are connected through generative operations or generative devices which account for the compositional interpretation of any linguistic utterance in a given context. This study analyses these different levels and focuses on one of them, i.e. the qualia structure since it may encode the conceptual meaning of the syntactic pattern [Radj+n]. The semantic study of these two lexical items has ultimately confirmed the conceptual meaning of the relational adjective. A corpus made of online ICT articles from magazines written in English and Spanish – some being their translations - has been used for the word extraction. For this purpose some word processing software packages have been employed. Moreover online general language and specialized language dictionaries have been consulted. Search engines, namely WordNet Search 3.1, have been also exploited to find the semantic information of our lexical units. Online reference corpora in English and Spanish have been used for a contrastive analysis of our data. Finally our conclusions have confirmed our initial hypotheses, i.e. relational adjectives are specialized lexical units which together with the nouns are part of the knowledge representation of the ICT subject field. Proposals for new research have been made together with some other suggestions for the design of computer applications to visually show the conceptual meaning of certain lexical units.

Cómic, arquitectura narrativa. Describiendo cuatro dimensiones con dos

Cómic, arquitectura narrativa. Describiendo cuatro dimensiones con dos. La mayor parte de los estudios con un enfoque académico en torno a cómic y arquitectura, se han centrado más en las distintas realidades representadas dentro del medio, en sus decorados, que en la estructura del cómic en sí. Existe un aspecto gráfico que se ha venido obviando o al menos no ha adquirido el protagonismo que merece: los espacios representados en el cómic se encuentran en un medio que se concibe y estructura de una manera similar a como el arquitecto dibuja y concibe la arquitectura. En lo básico, históricamente, las herramientas y soportes para idear y representar la arquitectura son muy parecidas a aquellas que usa el autor de cómic. Lápiz, tinta y color sobre un papel, combinadas trabajando en un tablero, ese es lugar de nacimiento de ambos mundos. A lo largo de esta tesis se muestra cómo el dibujo une a creadores de narraciones gráficas y edificios. La relación va más allá de que el cómic pueda utilizar las disposiciones vitruvianas, ichnographia, ortographia o scenographia, (planta, alzado, perspectiva), la propia articulación que hace del espacio de la página, puede sintonizar con la manera en la que se concibe una estructura arquitectónica. La tesis inicia con un capítulo de recorrido en torno a las teorías del cómic existentes, buscando intersecciones posibles con la representación arquitectónica o el proyecto espacial. En este primer paso de estudio del estado de la cuestión han pesado más los trabajos de los últimos veinticinco años. Se trata de un periodo en el que, a la par que se ha producido una explosión creativa en el mundo del cómic, determinados teóricos han incidido en un análisis más formal y visual del medio. Tras recoger teorías en el primer capítulo, se plantea un recorrido histórico a la búsqueda de posibles resonancias de “arquitecturas mentales” en el pasado. Esta búsqueda de referentes más allá del siglo XIX, momento en el que nace el medio en su forma actual, es ya un aspecto comúb en distintos estudios de cómic que han servido de inspiración. Se ha preferido ubicar esta colección de antecedentes como segundo capítulo, evitando dar al trabajo un carácter de historia e incidiendo en su enfoque de tipo visual. El tercer capítulo analiza una serie de obras y autores de cómic en su forma actual, buscando distintas estrategias para la descripción de espacios y las narraciones que ocurren en ellos. El crecimiento de casos en estas últimas décadas ha demostrado hasta qué punto el desarrollo de un campo depende tanto de que exista una masa crítica en un contexto conectado y productivo, como de la aparición de individuos que abren puertas a los demás, con la cristalización personal que hacen de una situación. Se analiza en un cuarto capítulo la relación entre la arquitectura y el cómic modernos. Una relación que se presenta partiendo desde sus respectivos padres, para después tratar un elenco creciente de experiencias en el que la narración gráfica y el hecho arquitectónico estan íntimamente ligados. Inspirado en la estrategia que Gubern y Gasca utilizan en El discurso del cómic (Cátedra, 1988) se cierra la tesis con un discurso visual por las arquitecturas mentales y narrativas del cómic: la representación del espacio a través de juego con las dimensiones, el uso de recursos gráficos propios de la descripción arquitectónica, la sección, la planta, la utilización de elementos constructivos,etc, completando el abanico de estrategias gráficas presentadas. ABSTRACT Comic narrative architecture. Describing four dimensions with two Most of the studies with an academic focus around comics and architecture have centered their view more on the different realities represented in the media, in its sets, than in the structure of comics itself. There is a graphic aspect that has been ignored, or at least has not gained the prominence it deserves: the spaces rendered in the comics are set in a medium that is conceived and structured in a similar way as the architect draws and conceives architecture. In basics, tools for designing and representing architecture are very similar to those used by the cartoonist. Pencil, ink and color on paper, combined working on a board, that is birthplace of both worlds. Throughout this thesis its shown how drawing connects creators of graphic stories and buildings. The relationship goes beyond the use that comics can do of the Vitruvian provisions, ichnographia, ortographia or scenographia (plan, elevation, perspective), to the arrange itself that it makes with space on the page, in tune with the way in which architectural structures are conceived. The thesis starts with a chapter that collects existing comics theories and their possible intersection with architectural rendering. In this first step of study on the state of affairs, the focus has been over studies from the last twenty years. It is a period in which, at the same time that there has been a creative explosion in the world of comics, some theorists have worked with a more formal and visual approach. After collecting theories in the first chapter, a historical tour is made to search for possible resonances of “mental architectures” in the past. This search for references beyond the nineteenth century, when the medium was born in its current form, is already a regular process in various recent studies that have served as inspiration. We preferred to locate this as a second chapter, to avoid giving the work a character of History, and reenforcing its visual approach. The third chapter analyzes a series of comics and authors, looking for different strategies for describing spaces and stories that occur in them. The growth of cases in recent decades has shown how the development of a field depends both on the existence of a critical mass in a connected and productive enviroment, and the appearance of individuals who open doors to others with the personal crystallization that they make on that context. The relationship between architecture and the modern comic is analyzed in a fourth chapter. A relationship that is described starting from their parents, and then going through a growing cast of experiences in which graphic narrative and architecture are closely linked. Inspired by the strategy used Gubern and Gasca in El discurso del cómic (Cátedra, 1988), The Comics’ Speech, the thesis concludes with a visual discourse through this narrative comic architectures: the representation of space by playing with dimensions, the use of resources for architectural rendering, section, plant, etc., to complete the range of graphical strategies presented.

An accurate model for simulating energetic behavior of PV grid connected inverters

This paper proposes a new model for characterizing the energetic behavior of grid connected PV inverters. The model has been obtained from a detailed study of main loss processes in small size PV inverters in the market. The main advantage of the used method is to obtain a model that comprises two antagonistic features, since both are simple, easy to compute and apply, and accurate. One of the main features of this model is how it handles the maximum power point tracking (MPPT) and the efficiency: in both parts the model uses the same approach and it is achieved by two resistive elements which simulate the losses inherent to each parameter. This makes this model easy to implement, compact and refined. The model presented here also includes other parameters, such as start threshold, standby consumption and islanding behavior. In order to validate the model, the values of all the parameters listed above have been obtained and adjusted using field measurements for several commercial inverters, and the behavior of the model applied to a particular inverter has been compared with real data under different working conditions, taken from a facility located in Madrid. The results show a good fit between the model values and the real data. As an example, the model has been implemented in PSPICE electronic simulator, and this approach has been used to teach grid-connected PV systems. The use of this model for the maintenance of working PV facilities is also shown.

Generalized optoelectronic model of series-connected multijunction solar cells

The emission of light from each junction in a series-connected multijunction solar cell both complicates and elucidates the understanding of its performance under arbitrary conditions. Bringing together many recent advances in this understanding, we present a general 1-D model to describe luminescent coupling that arises from both voltage-driven electroluminescence and voltage-independent photoluminescence in nonideal junctions that include effects such as Sah-Noyce-Shockley (SNS) recombination with n ≠ 2, Auger recombination, shunt resistance, reverse-bias breakdown, series resistance, and significant dark area losses. The individual junction voltages and currents are experimentally determined from measured optical and electrical inputs and outputs of the device within the context of the model to fit parameters that describe the devices performance under arbitrary input conditions. Techniques to experimentally fit the model are demonstrated for a four-junction inverted metamorphic solar cell, and the predictions of the model are compared with concentrator flash measurements.

Signing provision in connected TV: HBB4ALL project

This paper explains the work that the HBB4ALL project is carrying out to deploy signing services based on HbbTV (Hybrid Broadcast Broadband TV). HbbTV is an open standard specification for the new Connected TV technology, enabling interoperability of broadcast and broadband contents on the TV set. HBB4ALL proposes to take advantage of this broadcast-broadband convergence for the deployment of access services, including signing, due to the restrictions that this service has traditionally suffered.

Grid-Connected Forward Microinverter With Primary-Parallel Secondary-Series Transformer

This paper presents a primary-parallel secondaryseries multicore forward microinverter for photovoltaic ac-module application. The presented microinverter operates with a constant off-time boundary mode control, providing MPPT capability and unity power factor. The proposed multitransformer solution allows using low-profile unitary turns ratio transformers. Therefore, the transformers are better coupled and the overall performance of the microinverter is improved. Due to the multiphase solution, the number of devices increases but the current stress and losses per device are reduced contributing to an easier thermal management. Furthermore, the decoupling capacitor is split among the phases, contributing to a low-profile solution without electrolytic capacitors suitable to be mounted in the frame of a PV module. The proposed solution is compared to the classical parallel-interleaved approach, showing better efficiency in a wide power range and improving the weighted efficiency.

Delineating the Boundaries for Religious Speech in Public Discourse in Kierkegaard and Habermas

How is it that one of the most famous Christian thinkers - Soren Kierkegaard -- and one of the most famous contemporary secular thinkers -- Jurgen Habermas - both agree: the religious has nothing to say in the public realm of social, ethical discourse.

CONSOLIDAÇÃO OU MUDANÇA? UMA ANÁLISE FEMINISTA DA PASTORAL DA CRIANÇA

O objetivo central desta tese é investigar o potencial de transformação social da organização não-governamental, ligada a CNBB(Confederação Nacional dos Bispos do Brasil).- Pastoral da Criança - para a libertação de mulheres que lá atuam, das relações de dominação e opressões inerentes ao contexto kyriarchal. Esta pesquisa procura considerar o espaço religioso subjacente à organização em decorrência das influências das CEBs (Comunidades Eclesiais de Base) e do MRCC (Movimento de Renovação Católica Carismática). É feita pesquisa de campo na região de Curitiba com observações e entrevistas semi-estruturadas com doze mulheres atuando na Pastoral da Criança, valorizando-se a relação intersubjetiva entre pesquisadora e pessoas envolvidas na pesquisa. A análise qualitativa de dados em relação ao marco teórico feminista desenvolvido em Ciências Sociais pela sociologia, psicanálise e também a teologia, mostra o discurso das representações sociais das mulheres envolvidas, a percepção de suas próprias identidades e a importância da organização na construção de suas vidas. Nos traz a conclusão que a organização reproduz o perfil tradicional de mulheres na função materna e facilita a formação de redes comunitárias. Averigua-se que a Pastoral da Criança está vinculada ao sistema neoliberal de pensamento que reproduz os discursos de dominação do sistema kyriarchal da hierarquia da Igreja Católica e da medicina higienista. Essas instituições de apropriam da vida e dos corpos das mulheres e os reduzem às suas funções meramente biológicas, reprodutivas e de cuidados. A Pastoral da Criança é caracterizada por atividades que não consideram as causas estruturais da pobreza, mas apenas tentam amenizar os seus efeitos e conseqüências. Em suas capacitações, a organização usa a forma bancária de educação que reproduz as relações de dominação e dependência de mulheres pobres. A organização, mesmo com a estrutura da ideologia religiosa analisada, não está vinculada sistematicamente em um espaço religioso. Sugere-se em relação à situação da organização, a abertura das idéias e valores feministas nos campos da saúde e religião a fim de promover a libertação e empoderamento reais de mulheres pobres. Esta recomendação está ligada com a abertura, a necessidade de reflexão e de conhecimento, mostradas pelas mulheres entrevistadas durante a pesquisa de campo. Considera-se como limitação aos resultados da pesquisa, o local pesquisado por não ter influências de movimentos sociais.(AU)

A Cell-free System to Study Regulation of Focal Adhesions and of the Connected Actin Cytoskeleton

Assembly and modulation of focal adhesions during dynamic adhesive processes are poorly understood. We describe here the use of ventral plasma membranes from adherent fibroblasts to explore mechanisms regulating integrin distribution and function in a system that preserves the integration of these receptors into the plasma membrane. We find that partial disruption of the cellular organization responsible for the maintenance of organized adhesive sites allows modulation of integrin distribution by divalent cations. High Ca2+ concentrations induce quasi-reversible diffusion of β1 integrins out of focal adhesions, whereas low Ca2+ concentrations induce irreversible recruitment of β1 receptors along extracellular matrix fibrils, as shown by immunofluorescence and electron microscopy. Both effects are independent from the presence of actin stress fibers in this system. Experiments with cells expressing truncated β1 receptors show that the cytoplasmic portion of β1 is required for low Ca2+-induced recruitment of the receptors to matrix fibrils. Analysis with function-modulating antibodies indicates that divalent cation-mediated receptor distribution within the membrane correlates with changes in the functional state of the receptors. Moreover, reconstitution experiments show that purified α-actinin colocalizes and redistributes with β1 receptors on ventral plasma membranes depleted of actin, implicating binding of α-actinin to the receptors. Finally, we found that recruitment of exogenous actin is specifically restricted to focal adhesions under conditions in which new actin polymerization is inhibited. Our data show that the described system can be exploited to investigate the mechanisms of integrin function in an experimental setup that permits receptor redistribution. The possibility to uncouple, under cell-free conditions, events involved in focal adhesion and actin cytoskeleton assembly should facilitate the comprehension of the underlying molecular mechanisms.

Robust fitting of Zernike polynomials to noisy point clouds defined over connected domains of arbitrary shape

A new method for fitting a series of Zernike polynomials to point clouds defined over connected domains of arbitrary shape defined within the unit circle is presented in this work. The method is based on the application of machine learning fitting techniques by constructing an extended training set in order to ensure the smooth variation of local curvature over the whole domain. Therefore this technique is best suited for fitting points corresponding to ophthalmic lenses surfaces, particularly progressive power ones, in non-regular domains. We have tested our method by fitting numerical and real surfaces reaching an accuracy of 1 micron in elevation and 0.1 D in local curvature in agreement with the customary tolerances in the ophthalmic manufacturing industry.

The Vernacular Discourse of the "Arab Spring:" An Analysis of the Visual, the Embodied, and the Textual Rhetorics of the Karama Revolution

The Vernacular Discourse of the "Arab Spring" is a project that bridges the divide between the East and the West by offering new readings to Arab subjectivities. Through an analysis of the "Arab Spring" through the lens of vernacular discourse, it challenges the Euro-Americo-centric legacies of Orientalism in Western academia and the new wave of extremism in the Arab world by offering alternative representations of Arab bodies and subjectivities. To offer this new reading of the "Arab Spring," it explores the foundations of critical rhetoric as a theory and a practice and argues for a turn towards a critical vernacular discourse. The turn towards critical vernacular discourse is important as it urges the analyses of different artifacts produced by marginalized groups in order to understand their perspectives that have largely been foreclosed in traditional cultural studies research. Building on embodied/performative critical rhetoric, the vernacular discourses of the Arab revolutionary body examines other forms of knowledge productions that are not merely textual; more specifically, through data gathered in the Lhbib Bourguiba, Tunisia. This analysis of the political revolutionary body unveils the complexity underlining the discussion around issues of identity, agency and representation in the Middle East and North Africa, and calls for a critical study towards these issues in the region beyond the binary approach that has been practiced and applied by academics and media analysts. Hence, by analyzing vernacular discourse, this research locates a method of examining and theorizing the dialectic between agency, citizenry, and subjectivity through the study of how power structure is recreated and challenged through the use of the vernacular in revolutionary movements, as well as how marginalized groups construct their own subjectivities through the use of vernacular discourse. Therefore, highlighting the political prominence of evaluating the Arab Spring as a vernacular discourse is important in creating new ways of understanding communication in postcolonial/neocolonial settings.

Singular Temperatures Connected to Charge Transport Mechanism Transitions in Perylene Bisimides from Steady-State Photocurrent Measurements

Perylene bisimides (PBIs) are n-type semiconducting and photogenerating materials widely used in a variety of optoelectronic devices. Particularly interesting are PBIs that are simultaneously water-soluble and liquid-crystalline (PBI-W+LC) and, thus, attractive for the development of high-performing easily processable applications in biology and “green” organic electronics. In this work, singular temperatures connected to charge transport mechanism transitions in a PBI-W+LC derivative are determined with high accuracy by means of temperature-dependent photocurrent studies. These singular temperatures include not only the ones observed at 60 and 110 °C, corresponding to phase transition temperatures from crystalline to liquid-crystalline (LC) and from LC to the isotropic phase, respectively, as confirmed by differential scanning calorimetry (DSC), but also a transition at 45 °C, not observed by DSC. By analyzing the photocurrent dependence simultaneously on temperature and on light intensity, this transition is interpreted as a change from monomolecular to bimolecular recombination. These results might be useful for other semiconducting photogenerating materials, not necessarily PBIs or even organic semiconductors, which also show transport behavior changes at singular temperatures not connected with structural or phase transitions.

La representación de las mujeres inmigrantes en una muestra de la prensa española: deconstruyendo la invisibilidad

Esta investigación tiene como objetivo principal estudiar la representación de las mujeres inmigrantes en una muestra de la prensa española. Para ello, se recopiló un corpus de noticias sobre mujeres inmigrantes desde febrero de 2012 hasta julio de 2014, lo que suma un total de dos años y medio, de los tres principales periódicos españoles: El País, El Mundo y ABC. El número total de noticias recopiladas es de 56. En este estudio se analizarán los principales temas que se tratan en las noticias seleccionadas y las principales características lingüísticas y visuales empleadas para hablar sobre las mujeres inmigrantes. El análisis crítico del discurso (ACD) se empleará en este trabajo por su interés en la dimensión social del discurso al estudiar la lengua unida a temas sociales y por permitir profundizar en la ideología. En este sentido, el ACD puede ayudar a desentrañar problemas relacionados con las desigualdades de género al observar el modo en que las mujeres inmigrantes aparecen representadas en los textos objeto de estudio. Además, se empleará el modelo de gramática visual propuesto por Kress y van Leeuwen (2006) con el fin de analizar las principales características de las fotografías. Los principales resultados obtenidos del estudio señalan que la representación de las mujeres inmigrantes en la prensa española es escasa y que cuando éstas aparecen como protagonistas de noticias suelen representarse como víctima y se las relaciona fundamentalmente con la prostitución.
