A Poetics of Annotation: Alexander Pope's Footnotes

Studies of Alexander Pope's poetry tend to examine only the footnotes to his Dunciads, if they examine his footnotes at all. This dissertation will address this deficit in our understanding of Pope's poetics through an examination of Pope's use of footnotes in support of his verse throughout his career. With Gerard Genette's taxonomy of footnotes as variously paratext and text and Hugh Kenner's idea of the technological space of the printed page as frameworks within which Pope's footnotes operate, this dissertation will show that – over the course of his career – Pope developed a poetics of annotation that deployed footnotes rhetorically as appeals to ethos and pathos that both built up Pope's own authorial ethos for his audience in the literary market place of early eighteenth-century London and for posterity and used that authorial ethos in support of his literary and political friends.

An R-package for the Estimation and Testing of Multiple Covariates and Biomarker Interactions for Survival Data Based on Local Partial Likelihood

When we study the variables that a ffect survival time, we usually estimate their eff ects by the Cox regression model. In biomedical research, e ffects of the covariates are often modi ed by a biomarker variable. This leads to covariates-biomarker interactions. Here biomarker is an objective measurement of the patient characteristics at baseline. Liu et al. (2015) has built up a local partial likelihood bootstrap model to estimate and test this interaction e ffect of covariates and biomarker, but the R code developed by Liu et al. (2015) can only handle one variable and one interaction term and can not t the model with adjustment to nuisance variables. In this project, we expand the model to allow adjustment to nuisance variables, expand the R code to take any chosen interaction terms, and we set up many parameters for users to customize their research. We also build up an R package called "lplb" to integrate the complex computations into a simple interface. We conduct numerical simulation to show that the new method has excellent fi nite sample properties under both the null and alternative hypothesis. We also applied the method to analyze data from a prostate cancer clinical trial with acid phosphatase (AP) biomarker.

Fabricando falsas verdades: la prensa italiana de izquierdas y la construcción de la imagen de palestinos e israelíes (1947-1957)

El objetivo del presente estudio es analizar la forma en la que la prensa italiana de izquierdas construyó la imagen de palestinos e israelíes entre 1947 y 1957. La investigación se ha centrado en el estudio de los artículos publicados por algunos destacados periódicos de la época, con la finalidad de comprender cómo ha ido cambiando el lenguaje empleado por dichos órganos de prensa a la hora de referirse a los moradores de la tierra de Palestina. La tesis de este artículo es que dichos periódicos construyeron múltiples y contradictorias representaciones de judíos y palestinos, representaciones que no tenían nada que ver con la realidad de Oriente Medio, sino que obedecían a cuestiones ideológicas de carácter nacional e internacional (relaciones entre los partidos italianos y evolución de las dinámicas de la guerra fría).

Incised Pleistocene valleys in the Western Belgium coastal plain: Age, origins and implications for the evolution of the Southern North Sea Basin

The Belgian coastal plain occupies a key position as it is located at the transition between the Southern North Sea Basin and the Strait of Dover. It is characterized by thick sequences (> 20 m) of Pleistocene terrestrial and littoral sediments. Yet the wider stratigraphical and palaeo-environmental significance of these sediments received little attention. In this paper we draw on the results of a recent sedimentological study based on > 100 drillings that spans the Pleistocene sequence, and present new biostratigraphical (pollen, foraminifera, ostracods) data, all revealing a complex history of deposition. The record includes evidence of the development of incised-valley systems that were initiated in the late Middle and Late Pleistocene. Five phases of fluvial incision can be identified. The majority of the infills are deposited in an estuarine environment that passes into a fluvial environment land inward, except the Weichselian infill which has a predominant fluvial origin. The greatest part of the most seaward located zone of the western coastal plain was free of valley incisions, there, shallow marine sediments built up the record. Local biostratigraphical investigations provide a timeframe. The result is placed in a regional context.

History Matters: How International Regimes Become Entrenched—and Why We Suffer for It

International regimes are composite historical constructions. They are built-up through bricolage, as resource-strapped officials combine operational capacities, frequently turning to outside assistance. Who wins and loses—and why—when organisations are added or subtracted? What happens when inter-organisational relations are recalibrated? Why do regimes cohere as they do? By comparing the development of financial-regulatory regimes and probing other illustrative cases, I offer an explanatory framework that emphasizes the importance of timing and sequencing in determining outcomes. Thinking beyond interstate network effects and switching costs, I distil new data and theoretical insights into how and why temporality matters in global politics. I find that time structures the strategic bargaining contexts that mediate the intense distributional struggles between organisations driving key institutional reforms. The explanatory power of this framework upsets conventional wisdom whereby the distribution of state power, and the dynamics of interstate bargaining, are assumed the critical sources of institutional reform.

Bespoke Radiology e-Learning

Introduction: Foundation doctors are expected to assess and interpret plain x-ray studies of the chest/abdomen before a definitive report is issued by senior staff. The Royal College of Radiologists have published guidelines (RCR curriculum) on the scope of plain film findings medical students should be familiar with.1 Studies have shown that the x-ray interpretation without feedback does not significantly improve diagnostic ability. 2 Queen’s University, Belfast Trust Radiology and Experior Medical developed an online system to assess individual student ability to interpret X-ray findings. Over a series of assessments each student’s profile is built up, identifying strengths and weakness. The system can then create bespoke individual assessments re-evaluating previously identified weak areas and quantifying interpretative skill improvement. Aim: To determine how readily an online system is adopted by senior medical students, investigating if increasing exposure to x-ray interpretation combined with cyclical formative feedback enhances performance. Methods: The system was offered to all 270 final year medical students as an online resource. The system comprised a series of 20 weekly 30 minute assessments, containing normal and abnormal x-rays within the RCR curriculum. After each assessment students were given formative feedback, including their own result, annotated answers, peer group comparison and a breakdown of areas of strength and weakness. Focus groups of 4-5 students addressed student perspectives of the system, including ease of use, image resolution, system performance across different operating platforms, perceived value of formative feedback loops, breakdown of performance and the value of bespoke personalised assessments. Research Ethics Approval was granted for the study. Data analysis was via two-sided one-sample t-test; initial minimal recruitment was estimated as 60 students, to detect a mean 10% change in performance, with a standard deviation of 20%. Results and Discussion: Over 80% (n = XXX/270) of the student cohort engaged with the study. Student baseline average was 39%, increasing to 62% by the exit test. The steadily sustained improvement (57% relative performance in interpretative diagnostic accuracy) was despite increasing test difficulty. Student feedback via focus groups was universally positive throughout the examined domains. Conclusion: The online resource proved to be valuable, with high levels of student engagement, improving performance despite increasingly difficulty testing and positive learner experience with the system.

REPRESENTACIÓN DISCURSIVA DE UNIVERSIDADES ARGENTINAS EN LA PRENSA: RELEVAMIENTO Y VALORACIÓN DEL COMPONENTE LÉXICO-GRAMATICAL DE ARTÍCULOS PUBLICADOS EN MEDIOS DE COMUNICACIÓN DE DIFUSIÓN NACIONAL.

El trabajo releva la presencia de las universidades argentinas en la prensa de alcance nacional. Sistematizaremos la mención de ellas en la versión digital de los diarios para observar frecuencia de aparición y contenidos que se asocian. Partimos de la hipótesis de que los medios hegemónicos sólo registran los eventos de universidades del “interior del país” cuando se vinculan con hechos curiosos o violentos. Interesa indagar en qué casos particulares la referencia a dichas universidades se vincula con la producción y difusión académica del conocimiento científico, entre otras. Constituimos el corpus con fragmentos de textos periodísticos que permiten examinar estructuras gramaticales para develar las representaciones que la prensa naturaliza a través de esas formas. Seguimos consideraciones teórico-metodológicas de la Lingüística Crítica sobre el nivel sintáctico: cuando aparece una distorsión en la estructura superficial existe una manipulación ideológica del sentido. Incluimos parte de la teoría de las transformaciones: en el relato de un acontecimiento, cualquier alteración del esquema causa-consecuencia construye una ideología por la cual percibimos los hechos de otra manera. Asimismo, para establecer correlaciones semánticas en lo discursivo, analizaremos los términos en función de tipos de significado y valor eufórico/disfórico de la base léxica. Por otra parte, desde la Teoría de la Enunciación, distinguiremos palabras objetivas y subjetivas: los hechos enunciativos están constituidos por las huellas lingüísticas de la presencia del locutor en su enunciado, denominadas subjetivemas. Además de los pronombres, rasgos espaciales y temporales como marcas enunciativas, seleccionaremos unidades léxicas como sustantivos, adjetivos, verbos y adverbios. La existencia de los subjetivemas se fundamenta en que toda unidad léxica implica una interpretación del mundo, esto es, una ideología en el sentido que asumimos en nuestro trabajo desde el Análisis Crítico del Discurso. Como complemento de las perspectivas interpretativas mencionadas, realizaremos la cuantificación previa de referencias mediante el Análisis de Contenido como apoyo metodológico. A tal fin, el estudio prevé la utilización de una herramienta tecnológica diseñada ad hoc, para el conteo de frecuencia, relevamiento de contextos lingüísticos de aparición y asociaciones léxicas en la frase, como sistematización previa al trabajo cualitativo de valoración de estructuras léxico-semánticas y morfo-sintácticas. The research reflects the presence of Argentine universities in nationwide media. We will systematize their mention on online version of La Nación and Clarín newspapers to observe their frequency of appearance and the contents they are related to. With the hypothesis that hegemonic media only register events in universities from inside the country when they are related to curious or violent events, we will investigate in which particular cases the reference to such universities is related to the production and academic diffusion of scientific knowledge. We built up the corpus with fragments from articles which allow us to examine the deep grammatical structures to reveal the representation press naturalizes through these forms. We follow theoretical-methodological considerations of Critical Linguistics (CL) about the syntactical level: when a distortion in the superficial structure appears, there exists an ideological manipulation of meaning. Also, to establish semantic correlations on the discursive field, we will analyze terms as regards types of meaning and euphoric/disphoric value of lexical basis. From the Theory of Enunciation, we will distinguish between objective and subjective words (“subjectivemes”): lexical unit implies an interpretation of the world, that is, an ideology in the way we assume in our work from Critical Discourse Analysis (CDA). As a complement to CL and CDA, we will carry out a previous quantification using a technological tool designed ad hoc.

A dinâmica do campo organizacional e a adoção de estratégias na carcinicultura do RN

This study aimed to understand the relations inside the organizational Structuring of the shrimp Field - the shrimp agribusiness placed in Rio Grande do Norte State and the strategies adopted by its players. In order to achieve that, semi-structured interviews were conducted with samples of various organizations that act in the field, like cooperatives, associations, enterprises of different links in the chain, universities and state agencies. The interviews built up a large collection of secondary data. As expected, it was found that Field and strategies are related in a recursive way: the configuration of the field, a result from his own biography, has decisively influenced the strategies adopted by its actors, who, as evolved, eventually caused further changes in the Field and outlines the plot of this area of interaction. It was found, for example, that after thirty-five years of its genesis, the Field of shrimp RN still has a low level of institutionalization, which helps to understand the difficulty of its actors in establish strategies based on partnerships and cooperation; Those actions are so necessary to alleviate the effects of the crisis that devastated the industry since 2004. It was noticed, however, that this level of institutionalization is a result, beside other factors, the very strategies that field actors are embracing along its trajectory. Thus, this study hopes to have contributed both to the necessary revival of the agency to institutional phenomenon, cited by Oliver (1991), and to meet the need for more contextualized approaches to organizational strategies (MINTZBERG, 1987; CLEGG, 2004; WHITTINGTON, 2004; 2006; SARAIVA and CARRIERI, 2007). It is an exploratory study that needs further investigation in order to get deep in this research. In this sense, others methodologies and theoretical perspectives need to be used, especially those relating to the seizure of the disputes and discursive aspects of power, as salient in the field investigated. Moreover, in terms of "practical actions", it is suggested that, as soon as possible, the main actors of the field (cooperatives, companies, and state entities in class) can be able of agglutinate efforts to support the shrimp field in RN State and make sustainable actions, which can promote the development of activity in a global view. On the apse of shrimp activities everybody wanted to be the "father of the child," Now, someone has to "stay in the goal."

Supervisão colaborativa para uma educação inclusiva : um estudo com professores do ensino regular

Este trabalho, desenvolvido por uma professora de educação especial no contexto onde exerce funções, resultou da vontade de aprofundar o conhecimento sobre as dinâmicas de trabalho entre os professores do Ensino Regular e entre estes e o professor de Educação Especial. Desta forma elaborámos um projeto de investigação com o propósito de aprofundar o conhecimento sobre estas dinâmicas, no âmbito de uma oficina de formação, dinamizada pela investigadora, realizada no contexto de trabalho dos participantes. Neste âmbito, foi proporcionado um conjunto de experiências vivenciadas em conjunto, procurando contribuir para novas perspetivas teóricas sobre o conhecimento, bem como o envolvimento dos participantes em situações empíricas que lhes permitissem aplicar esses conhecimentos na resolução de problemas concretos emergentes no seu contexto de trabalho. A estratégia formativa baseou-se na colaboração como factor de desenvolvimento e de aprendizagem, surgindo como relevante e necessário o envolvimento dos formandos em processos de investigação da própria prática. A formação, na modalidade de Oficina, foi promovida através do Centro de Formação da Instituição onde a escola, um estabelecimento de ensino particular e cooperativo, se integra. Neste âmbito foi acreditada pelo Conselho Científico-Pedagógico da Formação Contínua e envolveu dezasseis professores do 1.º, 2.º e 3.º ciclos do ensino básico. A formação desenvolveuse em duas fases - a primeira fase, constituída por 4 sessões, teve lugar entre maio e julho de 2011, e a segunda fase, igualmente constituída por 4 sessões, teve lugar de setembro a novembro de 2011, num total de 25 horas presenciais e 25 horas não presenciais. Trata-se de um estudo com uma dupla intencionalidade – formativa e investigativa – no qual se procura compreender (i) a relação entre as estratégias de formação e supervisão promovidas pela professora de educação especial e o desenvolvimento de dinâmicas de trabalho colaborativo entre os participantes (ii) e o impacto dessas dinâmicas no desenvolvimento profissional e nas suas práticas, tendo em vista a promoção de uma educação inclusiva. Configura-se como estudo de caso, na variante de multicaso apresentando, ainda, algumas características de investigação-ação. No âmbito deste estudo, utilizámos um conjunto diverso e complementar de procedimentos investigativos, nomeadamente, o inquérito por questionário aplicado a todos os participantes no início e no fim da oficina de formação; o inquérito por questionário de avaliação das sessões, tendo por base os objetivos do estudo; a entrevista semi-estruturada, realizada a quatro docentes do 1º CEB que constituem os subcasos e o portfolio reflexivo individual dos mesmos, os quais se constituem como estratégia de formação e de investigação. Recorreu-se, ainda, como fontes de informação secundária, ao Teaching portfolio do investigador, às videogravações das sessões de formação, aos registos em vídeo de alguns episódios relativos à intervenção dos formandos em sala de aula e aos projetos de investigação-ação, bem como aos dados recolhidos na entrevista dirigida ao Diretor do estabelecimento de educação e ensino, depois de concluído o programa de formação. Os resultados da análise parecem evidenciar a existência de dinâmicas colaborativas e um clima de inter-ajuda que caraterizou a interação ocorrida na formação, em torno de casos concretos, os quais tiveram um impacto significativo sobre o pensamento e a prática dos participantes. Todo o processo desenvolvido parece ter dado lugar à partilha de saberes e à procura conjunta de soluções para os problemas, tendo contribuído para que os professores passassem a ser mais interventivos, evidenciando novas aprendizagens e uma maior consciencialização do conceito de educação para todos e do que esta implica. Os resultados parecem ainda revelar o desenvolvimento de uma parceria estratégica entre os professores do ensino regular e a professora de educação especial, a qual passou a ser aceite como uma pessoa que pode ajudar a encontrar soluções para os problemas que surgem na sala de aula, de forma a garantir a inclusão de todos os alunos e não apenas dos que têm necessidades educativas especiais.

Solar magnetic carpet II: coronal interactions of small-scale magnetic fields

This paper is the second in a series of studies working towards constructing a realistic, evolving, non-potential coronal model for the solar magnetic carpet. In the present study, the interaction of two magnetic elements is considered. Our objectives are to study magnetic energy build-up, storage and dissipation as a result of emergence, cancellation, and flyby of these magnetic elements. In the future these interactions will be the basic building blocks of more complicated simulations involving hundreds of elements. Each interaction is simulated in the presence of an overlying uniform magnetic field, which lies at various orientations with respect to the evolving magnetic elements. For these three small-scale interactions, the free energy stored in the field at the end of the simulation ranges from 0.2 – 2.1×1026 ergs, whilst the total energy dissipated ranges from 1.3 – 6.3×1026 ergs. For all cases, a stronger overlying field results in higher energy storage and dissipation. For the cancellation and emergence simulations, motion perpendicular to the overlying field results in the highest values. For the flyby simulations, motion parallel to the overlying field gives the highest values. In all cases, the free energy built up is sufficient to explain small-scale phenomena such as X-ray bright points or nanoflares. In addition, if scaled for the correct number of magnetic elements for the volume considered, the energy continually dissipated provides a significant fraction of the quiet Sun coronal heating budget.

Solar magnetic carpet III: coronal modelling of synthetic magnetograms

This article is the third in a series working towards the construction of a realistic, evolving, non-linear force-free coronal-field model for the solar magnetic carpet. Here, we present preliminary results of 3D time-dependent simulations of the small-scale coronal field of the magnetic carpet. Four simulations are considered, each with the same evolving photospheric boundary condition: a 48-hour time series of synthetic magnetograms produced from the model of Meyer et al. ( Solar Phys. 272, 29, 2011). Three simulations include a uniform, overlying coronal magnetic field of differing strength, the fourth simulation includes no overlying field. The build-up, storage, and dissipation of magnetic energy within the simulations is studied. In particular, we study their dependence upon the evolution of the photospheric magnetic field and the strength of the overlying coronal field. We also consider where energy is stored and dissipated within the coronal field. The free magnetic energy built up is found to be more than sufficient to power small-scale, transient phenomena such as nanoflares and X-ray bright points, with the bulk of the free energy found to be stored low down, between 0.5 - 0.8 Mm. The energy dissipated is currently found to be too small to account for the heating of the entire quiet-Sun corona. However, the form and location of energy-dissipation regions qualitatively agree with what is observed on small scales on the Sun. Future MHD modelling using the same synthetic magnetograms may lead to a higher energy release.

The storage and dissipation of magnetic energy in the quiet sun corona determined from SDO/HMI magnetograms

In recent years, higher cadence, higher resolution observations have revealed the quiet-Sun photosphere to be complex and rapidly evolving. Since magnetic fields anchored in the photosphere extend up into the solar corona, it is expected that the small-scale coronal magnetic field exhibits similar complexity. For the first time, the quiet-Sun coronal magnetic field is continuously evolved through a series of non-potential, quasi-static equilibria, deduced from magnetograms observed by the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory, where the photospheric boundary condition which drives the coronal evolution exactly reproduces the observed magnetograms. The build-up, storage, and dissipation of magnetic energy within the simulations is studied. We find that the free magnetic energy built up and stored within the field is sufficient to explain small-scale, impulsive events such as nanoflares. On comparing with coronal images of the same region, the energy storage and dissipation visually reproduces many of the observed features. The results indicate that the complex small-scale magnetic evolution of a large number of magnetic features is a key element in explaining the nature of the solar corona.

A percepção dos trabalhadores da enfermagem acerca da avaliação de desempenho do servidor público

A concepção de avaliação de desempenho dos trabalhadores da enfermagem, na maioria das vezes, é a de um ato de julgamento entre o certo e o errado, relacionado às ações e posturas desenvolvidas no contexto do seu trabalho. A avaliação de desempenho, no entanto, pode ser visualizada pelos trabalhadores como um importante instrumento que favorece o feedback do fazer profissional, desafiando-os a olharem para si mesmos, para o desenvolvimento de suas atribuições profissionais, proporcionando um real entendimento de sua importância na sociedade. Assim tem-se como objetivo geral conhecer a percepção dos trabalhadores da enfermagem de um Hospital Universitário localizado no extremo sul do Rio Grande do Sul (HU) acerca da sistemática da avaliação dos servidores públicos vivenciada na instituição e como objetivo específico conhecer a percepção dos trabalhadores da enfermagem do HU acerca da sistemática da avaliação dos servidores públicos no período do estágio probatório, adotada na instituição. Trata-se de uma pesquisa com abordagem qualitativa do tipo exploratória, desenvolvida com 70 trabalhadores de enfermagem. Para a coleta de dados utilizou-se a técnica de entrevista. Mediante a análise textual discursiva, construíram-se duas categorias: A avaliação do desempenho na concepção de trabalhadores da enfermagem e Serviço público: representatividade para o serviço da enfermagem. A avaliação do desempenho do servidor público pode ser influenciada pelo período de estágio probatório, pela sua vulnerabilidade na instituição, com possibilidade de conquistar a estabilidade ou perdê-la. Decorrido o período probatório, alguns trabalhadores modificam seu comportamento, demonstrando, por vezes, falta de comprometimento com seu fazer. No entanto, tal mudança pode estar relacionada com a cultura organizacional existente na instituição pública e, ainda, com um aparente descontentamento dos trabalhadores na realização da avaliação de desempenho, por não receberem um retorno significativo de cada avaliação. Pensar a sistemática de avaliação de desempenho com os trabalhadores da enfermagem significou a possibilidade de desencadear um processo de discussão e de reflexão sobre os diferentes modos de ser e fazer a enfermagem.
