The main established ones are operational, denotational and axiomatic semantics. The first two rely on defining an explicit model, whereas the latter one is based on postulating relevant properties of the language in terms of axioms. Particularly, in a purely algebraic approach the axioms take the form of conditional equations (typically denoted as programming laws) that relate the language constructs. Without requiring an explicit model, the advantage of the algebraic approach is incrementality: the language can be extended and the laws tend to remain valid, provided the new constructs do not interfere with the behaviour of the original ones. Algebraic laws have been proposed to uncover interesting properties of several programming paradigms: imperative, logic, functional, concurrent and object oriented, among others. As for the other paradigms, there is a comprehensive set of laws for object oriented constructs, but these are restricted to a language with copy semantics; some laws to deal with references have also been proposed, but these are tailored to specific applications, and are far from being comprehensive. In general, formal reasoning with references has been a persistent challenge and algebraic approaches usually have avoided including them in programming languages. We propose a set of algebraic laws for reasoning about object oriented programs with a reference semantics. First we focus on sequential imperative programs that use object references like in Java. The theory is based on previous work by adding laws to cope with object references. The incrementality of the algebraic method is fundamental; with a few exceptions, existing laws for copy semantics are entirely reused, as they are not affected by the reference semantics. As an evidence of relative completeness, we show that any program can be transformed, through the use of our laws, to a normal form which simulates it using an explicit heap with copy semantics. Soundness is addressed by illustrating how some of the laws can be proved in a relational semantics for a subset of the language. We extend the theory of imperative programs for an object oriented language with the usual constructs: additional imperative commands with references, classes with inheritance and subtyping, visibility control, dynamic binding, type tests and downcasts. Algebraic laws are proposed for these new constructs. In order to illustrate the expressiveness of the laws for the object oriented language, we characterize and prove a set of refactorings from Fowler’s catalog. These are contrasted with previous work that formalized refactorings in the context of copy semantics. Existem várias abordagens para descrever formalmente a semântica de linguagens de programação. As principais são semântica operacional, denotacional e axiomática. As duas primeiras definem modelos semânticos explícitos enquanto a última postula axiomas que descrevem propriedades relevantes da linguagem. Em uma abordagem puramente algébrica, os axiomas são equações (tipicamente denominadas leis de programação) que relacionam os diversos construtores da linguagem. A vantagem da álgebra é a facilidade de extensão: quando uma linguagem é estendida, a tendencia é que as leis já estabelecidas continuem sendo válidas, desde que os novos contrutores não interfiram com o comportamento dos construtores originais da linguagem Leis algébricas tem sido propostas para estudar propriedades interessantes de vários paradigmas de programação: imperativo, lógico, funcional, concorrente e orientado a objetos, entre outros. Em geral, para todos estes paradigmas existe um conjunto representativo de leis. Porém, para programação orientada a objetos, os trabalhos tem se restringido a linguagens com semântica de cópia ou as leis relacionadas com referências tem sido direcionadas somente para aplicações específicas e estão distantes de serem representativas. Em geral, raciocínio formal com referências tem sido um desafio persistente e os trabalhos algébricos usualmente tem evitado a inclusão de referências nas linguagens de programação. Propomos um conjunto de leis algébricas que permitem raciocinar com programas orientados a objetos com uma semântica de referências. Primeiro, focamos em uma linguagem imperativa sequencial que usa referências a objetos como em Java. A teoria é baseada em trabalhos anteriores adicionando leis que lidam com referências. A facilidade de extensão do método algébrico é fundamental; com poucas exeções, as leis anteriores para semântica de cópia são reusadas, pois elas não são afetadas pela semântica de referência. Como uma evidência de completude relativa, mostramos que qualquer programa pode ser transformado, usado as leis, em uma forma normal que simula o programa original usando um heap explícito com semântica de cópia. A consistência (soundness) das leis é abordada ilustrando como algumas das leis podem ser provadas em uma semântica relacional para um subconjunto da linguagem. Estendemos a teoria de programas imperativos para uma linguagem orientada a objetos com os habituais construtores: comandos imperativos adicionais com referências, classes com herança e subtipos, controle de visibilidade, amarração dinâmica, e testes e casts de tipos. Leis são propostas para estes novos construtores. Para ilustrar a expressividade das leis para a linguagem orientada a objetos, caracterizamos e provamos um conjunto de refatorações do catalógo clássico de Fowler. Comparamos nossa apresentação com trabalhos anteriores que formalizaram refatorações em um contexto de semântica de cópia.

Abstract:

Hoare and He's Unifying Theories of Programming (UTP) provides a rich model of programs as relational predicates. This theory is intended to provide a single framework in which any programming paradigms, languages, and features, can be modelled, compared and contrasted. The UTP already has models for several programming formalisms, such as imperative programming, higher-order programming (e.g. programing with procedures), several styles of concurrent programming (or reactive systems), class-based object-orientation, and transaction processing. We believe that the UTP ought to be able to represent all significant computer programming language formalisms, in order for it to be considered a unifying theory. One gap in the UTP work is that of object-based object-orientation, such as that presented in Abadi and Cardelli's untyped object calculi (sigma-calculi). These sigma-calculi provide a prominent formalism of object-based object-oriented (OO) programs, which models programs as objects. We address this gap within this dissertation by presenting an embedding of an Abadi--Cardelli-style object calculus in the UTP. More formally, the thesis that his dissertation argues is that it is possible to provide an object-based object rientation to the UTP, with value- and reference-based objects, and a fully abstract model of references. We have made three contributions to our area of study: first, to extend the UTP with a notion of object-based object orientation, in contrast with the existing class-based models; second, to provide an alternative model of pointers (references) for the UTP that supports both value-based compound values (e.g. objects) and references (pointers), in contrast to existing UTP models with pointers that have reference-based compound values; and third, to model an Abadi-Cardelli notion of an object in the UTP, and thus demonstrate that it can unify this style of object formalism.

Abstract:

A aprendizagem assistida por computador, conhecida mais amplamente com o nome genérico de e-learning, converteu-se numa poderosa ferramenta com amplas potencialidades dentro do campo educativo. Mesmo assim, uma das maiores críticas que esta recebe é que na maioria dos casos os cursos que são implementados seguem um enfoque “one size fits all”, isto é, que todos os alunos recebem exatamente o mesmo conteúdo e da mesma maneira desconhecendo suas necessidades particulares. Esta falha radica não só na falta de interação direita entre aluno e tutor, senão também na falta de um desenho instrucional apropriado que considere alguns dos diversos enfoques disponíveis hoje em dia. Existem diversos enfoques que procuram solucionar este problema e adaptar o processo de ensino os estudantes. Pode-se dizer que na vanguarda de estes enfoques encontram-se os Sistemas Educacionais Inteligentes Adaptativos, os quais combinam as funcionalidades de dois enfoques: os Sistemas Hipermídia Educacionais Adaptativos y os Sistemas Tutoriais Inteligentes. Embora, logo de uma extensa revisão bibliográfica, se encontrou que existe ainda um inconveniente importante com este tipo de sistemas e em particular com seus modelos de referência: ou são demasiado simples, incluindo somente umas poucas funcionalidades; ou são demasiado complexos, o que dificulta seu desenho e implementação. Considerando este panorama, o objetivo principal de esta tese foi a definição de um modelo de referência intentando alcançar esse equilíbrio esquivo, de tal maneira que permita o desenho de cursos que se adaptem de una maneira efetiva e inteligente ao progresso e características de cada estudante, mas sem ser demasiado complexo. Outra propriedade importante desse modelo és que integra o uso de Objetos de Aprendizagem, promovendo assim a flexibilidade e a usabilidade. Para alcançar este objetivo geral, três sub modelos foram considerados: um modelo do domínio, um modelo do estudante y um modelo do tutor. O primeiro serve para estruturar o domínio de conhecimento e foi definido usando a noção de objetivo de aprendizagem junto com um esquema flexível multi-nível com operações opcionais de pré-requisitos. O segundo visa caracterizar aos estudantes e considera informação pessoal, de conhecimento e psico-cognitiva. O terceiro pode ser considerado como o coração do sistema e define as funcionalidades adaptativas consideradas: sequenciamento y navegação, apresentação de conteúdo, evacuação, y suporte colaborativo. Com o fim de clarificar os três sub modelos, assim como todos seus componentes e relações, se presentou um exemplo de instanciação que se denominou Doctus, o qual consiste em una ferramenta de autor para cursos adaptativos. Doctus não somente serviu para exemplificar o uso do modelo de referência em sua totalidade, mas também para refinar os sub modelos e alguns procedimentos involucrados. Como parte final de esta tese, se realizou também a implementação e validação preliminar de Doctus. Isto foi feito com 51 sujeitos, professores em diversos níveis de formação. Os resultados obtidos em esta etapa foram sobressalientes no sentido que todas as funcionalidades adaptativas foram bem avaliadas e todos os pesquisados manifestaram seu entusiasmo por contar com uma ferramenta que lhes ajudara em seus práticas docentes considerando a seus estudantes como indivíduos particulares. Computer Aided Learning, known more widely with the generic name of e-learning, has become a powerful tool with lots of potentialities within educational field. Even though, one of the main critics that it receives is that in most cases the implemented courses follows a “one size fits all” approach, which means that all students receive the same content in the same way being unaware of their particular needs. This problem is not due only to the absence of direct interaction between student and tutor, but also because of the lack of an appropriate instructional design. There are several approaches which deal with this issue and look for adapt the teaching process to students. One could say that in the top of those approaches the Adaptive and Intelligent Educational Systems are situated, which merges the functionalities of two approaches: the Adaptive Educational Hypermedia Systems and the Intelligent Tutoring Systems. Nevertheless, after an extensive literature review, a major inconvenience is still found for this kind of systems and particularly for their reference models: or they are too simple, including just a few functionalities; or they are too complex, which difficult their design and implementation. Considering this panorama, the main objective of this dissertation thesis was the definition of a reference model trying to reach such an elusive equilibrium, in such a way that allows the design of courses which adapt themselves in an intelligent and effective way to the progress and characteristics of each student but without being too complex. Another important feature is that this model integrates Learning Objects, promoting this way flexibility and reusability. In order to achieve this general objective, three sub-models were considered: a domain model, a student model and a tutor model. The first one serves to structure the knowledge domain and was defined using the notion of learning goal and a flexible multilevel schema with optional prerequisite operations. The second one aids to characterize students and considered personal, knowledge and psycho-cognitive information. The third one may be considered as the hearth of the system and defines the adopted adaptive functionalities: sequencing and navigation, content presentation, assessment, and collaborative support. With the aim of clarify the three sub-models, as well as all their components and relationships, an instantiation example was also presented. Such an instantiation was called Doctus, an authoring tool for adaptive courses. Doctus was not only helpful to exemplify the setup of the referece model as a whole, but also to refine sub-models and several procedures envolved. As final part of the dissertation, the implementation and preliminary validation of Doctus was performed. This was done with 51 subjects, teachers from different formation levels. The obtained results in this stage were outstanding, all the adaptive functionalities were well evaluated and all of those polled felt enthusiastic about counting with a tool for helping them in their teaching practices considering students as particular individuals.

Como consequência dessa negação, Frege apresenta a estrutura de Sentido e Referência, como alternativa às possibilidades anteriormente apresentadas. Em decorrência dessa ruptura, a dimensão da filosofia analítica desenvolvida por Frege se amplia, revelando um complexo sistema no qual o verdadeiro se torna o ponto fundamental. Mostramos que, no processo de reformulação do significado do verdadeiro, Frege diferencia, ainda nos Fundamentos da Aritmética, o domínio do campo objetivo efetivo do campo objetivo não-efetivo, espaço lógico no qual as leis do ser verdadeiro encontram lugar como referência para as proposições que expressam o pensamento analítico. Visamos demonstrar que, partindo dessa fundamentação inicial, o autor almeja estabelecer uma conexão ontológica entre o pensamento e as leis do ser verdadeiro, o que lhe permite distinguir, em “Sobre o Sentido e Referência”, o pensamento que expressa uma representação ou ideia, pertencente ao domínio subjetivo, do pensamento que expressa as leis do ser verdadeiro, e que podem ser transmitidas em gerações, por pertencerem ao domínio objetivo não-efetivo. Buscamos estabelecer uma conexão entre essas diretrizes e a concepção de pensamento fregiano, justificando a composição deste como sendo uma estrutura que atende ao princípio de saturação, que não se articula na forma sujeito/predicado e que, para poder atender à necessidade lógica de passar do sentido para a referência e ser nomeado como o verdadeiro, se articula com a lógica extensional e, em um sentido ainda mais intrínseco, com uma lógica da existência, que surge como a estrutura basilar na qual se fundamenta o juízo, e sem o qual não poderia haver a validação ontológica do pensamento analítico de Frege. In “On Sense and Reference”, Frege announces a break with his previous works, notably Ideography, in which he had assumed that equality was referring to the names and signals representative of the objects. As a result of this denial, Frege presents the structure of Sense and Reference, as an alternative to possibilities previously presented. Due to this break, the dimension of analytic philosophy developed by Frege expands, revealing a complex system in which the true becomes the key point. We show that, in the process of recasting the meaning of true, Frege differentiates, still in the Foundations of Arithmetic, the domain of effective objective field of the noneffective objective field , the logical space in which the laws of true being has a place as a reference to the propositions expressing analytical thinking. We aim to demonstrate that, based on this initial foundation, the author aims to establish an ontological connection between the thought and the laws of true being, allowing him to distinguish, in “On Sense and Reference”, the thought that expresses an idea or representation, belonging to subjective realm, of thought which expresses the laws of true being, and that can be transmitted in generations, because they belong to the non-effective objective field. We strive to establish a connection between these guidelines and the conception of fregian thought, justifying the composition of this as being a structure that follows the principle of saturation, which is not articulated in the form subject / predicate, and that in order to meet the logical necessity of moving beyond of sense to reference and be named as the true, articulates with the extensional logic and, in a more intrinsic meaning , with a logic of existence that emerges as the framework in which the judgment is based , and without which it could not be the ontological validation of analytical thinking Frege.

Abstract:

In this thesis, I examine human-like language generation from a visual input head-on, exploring how people refer to visible objects in the real world. Using previous work and the studies from this thesis, I propose an algorithm that generates humanlike reference to visible objects. Rather than introduce a general-purpose REG algorithm, as is tradition, I address the sorts of properties that visual domains in particular make available, and the ways that these must be processed in order to be used in a referring expression algorithm. This method uncovers several issues in generating human-like language that have not been thoroughly studied before. I focus on the properties of color, size, shape, and material, and address the issues of algorithm determinism and how speaker variation may be generated; unique identification of objects and whether this is an appropriate goal for generating humanlike reference; atypicality and the role it plays in reference; and multi-featured values for visual attributes. Technical contributions from this thesis include (1) an algorithm for generating size modifiers from features in a visual scene; and (2) a referring expression generation algorithm that generates structures for varied, human-like reference.

Abstract:

As a result of the rapid evolution of smart mobile devices and the wide application of satellite-based positioning devices, the moving object database (MOD) has become a hot research topic in recent years. The moving objects generate a large amount of geo-referenced data in different types, such as videos, audios, images and sensor logs. In order to better analyze and utilize the data, it is useful and necessary to visualize the data on a map. With the rise of web mapping, visualizing the moving object and geo-referenced data has never been so easy. While displaying the trajectory of a moving object is a mature technology, there is little research on visualizing both the location and data of the moving objects in a synchronized manner. This dissertation proposes a general moving object visualization model to address the above problem. This model divides the spatial data visualization systems into four categories. Another contribution of this dissertation is to provide a framework, which deals with all these visualization tasks with synchronization control in mind. This platform relies on the TerraFly web mapping system. To evaluate the universality and effectiveness of the proposed framework, this dissertation presents four visualization systems to deal with a variety of situations and different data types.

Abstract:

This thesis describes a computational model for interpreting natural language expressions in an interactive multimodal query system integrating both natural language text and graphic displays. The primary concern of the model is to interpret expressions that might involve graphical attributes and expressions whose referents could be objects on the screen. Graphical objects on the screen are used to visualise entities in the application domain and their attributes (in short, domain entities and domain attributes). This is why graphical objects are treated as descriptions of those domain entities/attributes in the literature. However, graphical objects and their attributes are visible during the interaction, and are thus known by the participants of the interaction. Therefore, they themselves should be part of the mutual knowledge of the interaction. This poses some interesting problems in language processing. As part of the mutual knowledge graphical attributes could be used in expressions, and graphical objects could be referred to by expressions. In consequences, there could be ambiguities about whether an attribute in an expression belongs to a graphical object or to a domain entity. There could also be ambiguities about the referent of an expression is a graphical object or a domain entity. The main contributions of this thesis consist of analysing the above ambiguities, designing, implementing and testing a computational model and a demonstrational system for resolving these ambiguities. Firstly, a structure and corresponding terminology are set up, so these ambiguities can be clarified as ambiguities derived from referring to different databases, the screen or the application domain (in short, source ambiguities). Secondly, a meaning representation language is designed which explicitly represents the information about which database an attribute/entity comes from. Several linguistic regularities inside and among referring expressions are described so that they can be used as heuristics in the ambiguity resolution. Thirdly, a computational model based on constraint satisfaction is constructed to resolve simultaneously some reference ambiguities and source ambiguities.

Abstract:

In two experiments, many annotators marked antecedents for discourse deixis as unconstrained regions of text. The experiments show that annotators do converge on the identity of these text regions, though much of what they do can be captured by a simple model. Demonstrative pronouns are more likely than definite descriptions to be marked with discourse antecedents. We suggest that our methodology is suitable for the systematic study of discourse deixis.

Abstract:

The thesis underpinning this study is as follows; it is possible to build machine models that are indistinguishable from the mental models used by humans to generate language to describe their environment. This is to say that the machine model should perform in such a way that a human listener could not discern whether a description of a scene was generated by a human or by the machine model. Many linguistic processes are used to generate even simple scene descriptions and developing machine models of all of them is beyond the scope of this study. The goal of this study is, therefore, to model a sufficient part of the scene description process, operating in a sufficiently realistic environment, so that the likelihood of being able to build machine models of the remaining processes, operating in the real world, can be established. The relatively under-researched process of reference object selection is chosen as the focus of this study. A reference object is, for instance, the `table' in the phrase ``The flowers are on the table''. This study demonstrates that the reference selection process is of similar complexity to others involved in generating scene descriptions which include: assigning prepositions, selecting reference frames and disambiguating objects (usually termed `generating referring expressions'). The secondary thesis of this study is therefore; it is possible to build a machine model that is indistinguishable from the mental models used by humans in selecting reference objects. Most of the practical work in the study is aimed at establishing this. An environment sufficiently near to the real-world for the machine models to operate on is developed as part of this study. It consists of a series of 3-dimensional scenes containing multiple objects that are recognisable to humans and `readable' by the machine models. The rationale for this approach is discussed. The performance of human subjects in describing this environment is evaluated, and measures by which the human performance can be compared to the performance of the machine models are discussed. The machine models used in the study are variants on Bayesian networks. A new approach to learning the structure of a subset of Bayesian networks is presented. Simple existing Bayesian classifiers such as naive or tree augmented naive networks did not perform sufficiently well. A significant result of this study is that useful machine models for reference object choice are of such complexity that a machine learning approach is required. Earlier proposals based on sum-of weighted-factors or similar constructions will not produce satisfactory models. Two differently derived sets of variables are used and compared in this study. Firstly variables derived from the basic geometry of the scene and the properties of objects are used. Models built from these variables match the choice of reference of a group of humans some 73\% of the time, as compared with 90\% for the median human subject. Secondly variables derived from `ray casting' the scene are used. Ray cast variables performed much worse than anticipated, suggesting that humans use object knowledge as well as immediate perception in the reference choice task. Models combining geometric and ray-cast variables match the choice of reference of the group of humans some 76\% of the time. Although niether of these machine models are likely to be indistinguishable from a human, the reference choices are rarely, if ever, entirely ridiculous. A secondary goal of the study is to contribute to the understanding of the process by which humans select reference objects. Several statistically significant results concerning the necessary complexity of the human models and the nature of the variables within them are established. Problems that remain with both the representation of the near-real-world environment and the Bayesian models and variables used within them are detailed. While these problems cast some doubt on the results it is argued that solving these problems is possible and would, on balance, lead to improved performance of the machine models. This further supports the assertion that machine models producing reference choices indistinguishable from those of humans are possible.

No. of bitstreams: 1 2016 - Erick Augusto Cabral.pdf: 5011974 bytes, checksum: ca52656e5f77bfd68ff25c37627f5d7a (MD5) Previous issue date: 2016-12-12 CAPES According to variational researches (cf. DUARTE, 1989; AVERBUG, 1998, 2000, 2007; FREIRE, 2000; 2005; 2011), the strategies that appear in the Brazilian Portuguese instead of accusative clitic for representation of the anaphoric direct object of third person are nominative pronoun, anaphoric NP and null object. This research, based on theoretical and methodological backgrounds from Grammar of the Text and Variationist Sociolinguistics, aims to investigate the frequency of the aforementioned variants on writing of ninth grade students from elementary school, in continuum orality-literacy (cf. BORTONI-RICARDO, 2004), to check whether the school can influence on the students? writing. Plus, we intent to guide these students to realize the relevance of each of the variants in orality events or literacy events, so that they can use those variants in different linguistic contexts. For this purpose, we selected three genres distributed along this continuum: comic strip which is considered a representation of the oral speech, chronicles which stands halfway this continuum, and, finally, the newspaper articles which represents the other pole of the continuum, due to their higher degree of literacy. In order to achieve the objectives, we developed a teaching sequence, which allowed to work with diferent texts, from the diagnosis to the final productions. The results showed, on the one hand, that the accusative clitic is not part of natural grammar of students, it depends on educational process; on the other hand, the use of nominative pronoun as direct object is still very much present in the writing of students, even in representative genres of literate culture as the newspaper reports, which signals that school must promote the students? literacy process, especially to make them able to handle the prestige linguistic structures. Segundo pesquisas variacionistas (cf. DUARTE, 1989; AVERBUG, 1998, 2000, 2007; FREIRE, 2000; 2005; 2011), as estrat?gias que aparecem no portugu?s do Brasil em lugar do cl?tico acusativo (pronome ?tono) para representa??o do objeto direto anaf?rico de terceira pessoa s?o o pronome nominativo (pronome reto), o sintagma nominal anaf?rico e o objeto nulo (categoria vazia). Assim, esta pesquisa, baseada nos pressupostos te?rico-metodol?gicos da Gram?tica do Texto e da Sociolingu?stica Variacionista, tem por objetivo investigar a frequ?ncia das variantes supracitadas na escrita de alunos do 9? ano do EF num cont?nuo oralidade-letramento (cf. BORTONI-RICARDO, 2004), a fim de verificar se a escolariza??o exerce ou n?o efeito sobre a escrita dos alunos, bem como levar esses mesmos alunos a perceber a pertin?ncia de cada uma das variantes usadas na realiza??o da vari?vel em eventos de oralidade ou de letramento, de maneira que possam empregar, em diferentes contextos de uso da l?ngua, as variantes candidatas ? representa??o do objeto direto anaf?rico de terceira pessoa. Dessa forma, foram selecionados tr?s g?neros, organizados ao longo do referido cont?nuo: hist?rias em quadrinhos (HQs), representativas de textos mais orais; cr?nicas, consideradas textos intermedi?rios nessa escala; reportagens, textos tidos como representantes da cultura de letramento. Para alcan?ar os objetivos desta pesquisa, foi elaborada uma sequ?ncia did?tica, que permitiu trabalhar o uso das variantes em textos dos g?neros selecionados, desde a diagnose at? a produ??o final. Os resultados mostraram, por um lado, que a variante cl?tico acusativo n?o faz parte da gram?tica natural dos alunos, sendo resultado de um processo de escolariza??o; por outro, que a variante pronome lexical ainda ? bem presente na escrita de estudantes para representa??o do objeto direto anaf?rico de terceira pessoa, mesmo em g?neros representativos da cultura letrada como a reportagem, o que sinaliza a necessidade de um trabalho constante da escola no sentido de promover o processo de letramento dos alunos, especialmente no que diz respeito ao manejo de estruturas lingu?sticas t?picas das variedades urbanas de prest?gio.

Abstract:

The Bantu languages Swahili (G42, Tanzania) and Makhuwa (P31, Mozambique) show a high degree of structural similarity, but differ significantly with respect to their morphological systems of object marking; whereas Swahili has complex paradigm of object markers based on 15 noun class distinctions, in Makhuwa object markers exist only for two classes (1 and 2). Based on original data from Makhuwa-Meeto and Swahili, the thesis explores the implications of this morphological difference for the discourse structures of the two languages. Object markers are a central part of anaphoric relations in Bantu languages, and the thesis shows how other elements interact with them in both languages. The results of the study show that the correlation between morphology and discourse is complex; while there are differences in referential density (the ratio between expressed and nonexpressed verbal arguments) between Makhuwa and Swahili, both languages exhibit a high degree of object ellipsis. Pronouns fulfil focus-related and emphatic functions in both languages, and so are rarely used for anaphoric reference, but Makhuwa shows a stronger tendency to use full noun phrases in anaphoric contexts. More generally, the results of the thesis contribute to our understanding ofMakhuwa and Swahili object expressions, as well as to a small but growing number of studies on discourse structures in Bantu languages, to the comparative study of Bantu morphosyntax, and to the expression of anaphoric relations in discourse more widely.

Abstract:

Vectors, defined by distance and direction information, can represent the spatial relationships between reference objects and target objects. Reference boundaries help to define the space and are mathematically definable by lines, while reference landmarks define specific locations and are definable by points. How do vectors, containing two sources of information relate references and targets? Congruent with neuroscientific evidence we argued that humans rely differentially on distance and direction information when recalling the spatial location of objects. We showed that direction information was better encoded or remembered than distance information relative to landmarks, and that distance information was better encoded or remembered than direction information relative to boundaries. We proposed that the type of reference influences the fidelity of distance and direction information in the spatial representation.

Full text

Abstract:

A theory of descriptive names is developed and defended against several objections. Descriptive names pose an interesting challenge to any theory of reference, since they possess both features of proper names and definite descriptions, i.e. of expressions which are often considered to be radically different. These features are referentiality and descriptive sense. The thesis takes as its point of departure Gareth Evans's theory of descriptive names, improves upon it and discusses several other authors and related theories along the way. Chapter I provides an brief introduction to the topic and an abstract of the main lines of argument. Chapter 2 argues that descriptive names possess both referential status and descriptive sense, and that these qualities constitute the two most basic elements of the notion of descriptive reference (which is contrasted with Russellian reference). It is demonstrated that not all names introduced by description are descriptive names, a claim which is given additional substance by a comparison between Evans's and Kripke's accounts of such names. Chapters 3 and 4 deal with two major challenges to the possibility of descriptive names. Chapter 3 explores the possibility of a truth-conditional theory of meaning for descriptive names, but it is shown that if we follow Evans's suggestion that the semantic value of a descriptive name is to be construed according to model theory - namely, as an entity distinct from the referent (a set) - such a theory will result in treating descriptive names as predicates, and thus eliminate then qua referring expressions. Similar accounts given by other authors are also examined and found to be problematic. I conclude by rejecting the model-theoretic notion of semantic value. Chapter 4 addresses a second challenge, posed by the fact that if a descriptive name has a descriptive sense, then given a Russellian analysis of definite descriptions, descriptive names must be quantifier phrases, and thus, again, non-referring expressions. It is argued that if this is true, then the use of negative free logic is unnecessary. Using the idea of rigidified descriptions, it is shown that Evans's arguments, based on modality and simplicity considerations, fail to save both the referentiality and descriptive sense of descriptive names while semantically dissociating them from descriptions. I show that descriptive names can be treated as shorthand for rigidified descriptions and thus semantically on a par with the latter, which, as I demonstrate, is still consistent with Evans's own (convincing) solution of the puzzle of the contingent a priori. Nevertheless, this still does not guarantee the referentiality of descriptive names. Chapter 5 presents in detail the argument that we can only save the referentiality and descriptive sense of descriptive names if we treat definite descriptions as referring expressions. Several negative arguments undermining the most influential defences of the Russellianism are given and three positive accounts of referring descriptions, Wettstein's, Sainbury's and Strawson's, are critically discussed, finally settling, with some proviso, for Strawson's. Finally, the principles of a 'Fregean' free logic for Strawsonian semantics are sketched, and I suggest ways in which a truth theory could be expressed by means of these principles. Chapter 6 summarises the achievements, sketches possible research concerning descriptive names and concludes that the analysis of descriptive names is useful in at least three ways: it provides us with means to, first, solve problems that arise from the introduction of artificial expressions such as descriptive names (e.g. the problem of the contingent a priori), second, to better understand our natural language and its relation to formal theories of meaning, and, last but not least, to give a strong rationale for a referential treatment of definite descriptions. Chapter 7 includes the bibliography and Chapter 8 a list of axioms and formulas.

Abstract:

Approved for public release, distribution is unlimited This thesis critically analyzes the Sharable Content Object Reference Model (SCORM) within higher education and examines SCORM's limitations within a realistic application environment versus within a theoretical/conceptual platform. The thesis also examines environments better suited for implementation of SCORM technology. In addressing the research questions, it was discovered that from the current standards set forth by Advanced Distributed Learning (ADL), SCORM is not well suited for higher education. SCORM technology will prove of greater utility within the Navy Training environment than in higher education. In their effort to share information, higher education institutions would benefit more from a Content Management System in conjunction with a Learning Management System. Subsequent chapters addressed the limitations of SCORM, provided a comparison of the applicability of SCORM within the separate domains of naval Education and Training, and provided a prototype of a Content Management System for institutions of higher learning.

Abstract:

This thesis investigates a specific kind of criticism of the token-token identity-theory. This criticism is based on recent theories of reference. In the Introduction I argue that more than Davidson's three premisses is needed to establish that mental events are identical to physical events. One needs to invoke principles about what constitutes event-identity. In Part 1 I discuss event-identities. I lay down the constraints an adequate theory of event-identity must satisfy, and criticise the major theories in the literature. I suggest an alternative view, which I defend against some recent proposals. I end Part 1 by exploring a view which takes seriously the possibility of constitution-relations between events. In Parts 2 and 3 I discuss whether the identity-theory can be defended. Part 2 discusses sensations, and I concentrate on S. Kripke's arguments against the identity-view. I distinguish two versions of Kripke's argument, one epistemic, and one metaphysical. The epistemic version of the argument presupposes Kripke's views on content, but fails by its own standards. The metaphysical version is shown to be weak and implausible. Part 3 discusses cognitive events, and concentrates on de re beliefs. I produce an argument which apparently defeats the identity-view. I elaborate two main strategies in defence of the identity-theory. I argue that given a theory of de re beliefs or singular thoughts like G. Evans's, the theory of event-identities I have developed, and some plausible further premisses, the identity-theory seems to be defeated. A reasonable interpretation of this result is to view it as an argument for constitution-relations between mental and physical events. I return to the view I introduced in part 1, and conclude that the token-token identity-theory should probably be replaced by this constitution-view if theories of de re beliefs are accepted.

Abstract:

This essay deals with certain problems in the theory of singular reference. The following question is taken as central: What role is to be assigned to nonempty and syntactically simple singular terms in fixing the semantic contents of utterances of declarative sentences in which they may occur? I focus on those aspects of the current dispute between Millian and neo-Fregean approaches to singular reference which are related to issues about the cognitive significance of language use; the following two issues are singled out as crucial: the issue about (alleged) potential differences in informativeness between sentences constructed out of co-referential singular terms; and the issue about (alleged) failures of substitutivity salva veritate of co-referential singular terms in propositional-attitude contexts. The general direction of my arguments is as follows. On the one hand, I argue that "notational variance" claims recently advanced on both sides of the dispute should be deemed unsound; and hence that one is really confronted with separate accounts of singular content. On the other, I argue that Milllanism does not provide us with a satisfactory solution to the problems about cognitive significance; and hence that a framework of singular senses is Indispensable to deal with such problems in an adequate way. I also discuss the problem of Cognitive Dynamics, i.e. the issue of attitude-retention and persistence of mental content, in connection with the individuation of indexical thought. I argue that the standard Intuitive Criterion of Difference for thoughts might be reasonably extended to the diachronic case, allowing thus the possibility of discriminating between thoughts entertained by a thinker at different times.

Abstract:

Master of Science Department of Computing and Information Sciences Mitchell Neilsen The Biosecurity Research Institute (BRI) facility at Kansas State University is a huge biocontainment facility to conduct research on infectious diseases that pose a threat to plant, animal and human health. The BRI Training and Education Program is currently offline; i.e., classroom sessions are taken to provide this training and education. The objective behind taking up this project was to move the entire training and education module of Biosecurity Research Institute online, instead of having a classroom session for each training course, with an subject matter expert (SME) to come and take the training session. The aim is to develop an online training system which is synchronized with the information in the BRI Research Project Database. The employees will only have to login to the website, scroll through the list of courses they are enrolled in, take the courses, write the assignments/quizzes assigned to the course and then submit the quizzes. They can also self-enroll themselves into courses, if they are given the permission to do so. The SME’s of the courses can create new courses, upload the course materials, enroll users into the courses, and assign deadlines to course completion. Once the student submits the course quiz or assignments, the SME’s can grade the quiz, assign a final grade to the students, and give feedback on their performance. They can even reassign the course in case of poor performance by the student. The administrators of the website can assign roles to different personnel, give permissions according to need and requirement, add/delete courses, and change the appearance of the website. The project is to be done using a Learning Management System called Moodle. Moodle (Modular Object Oriented Dynamic Learning Environment) is an online learning management system designed to allow interaction between teachers and students. The back-end database used is SQL Server 2008 R2 and additional tools used are Adobe Presenter (with Microsoft Power Point 2010) to create the courses in SCORM format.

Abstract:

Approved for public release; distribution in unlimited. The thesis research examines the emergence of Sharable Content Object Reference Model (SCORM) architecture currently under development by the Advanced Distributed Learning (ADL) initiative established by the Department of Defense (DoD). SCORM is a collection of specifications adapted from multiple sources to provide a comprehensive suite of E-Learning capabilities that enable interoperability, accessibility, and reusability of Web-based learning content. To understand better the implementation issues of SCORM architecture, the authors analyze all versions of SCORM to understand the evolution of this emerging architecture. It contrasts the evolving requirements for shareable content objects with concerns of copyright issues. The authors address development and implementation issues surrounding the maturation of SCORM architecture and the ADL initiative. The authors recommend that DoD, international, and civilian business partners join in improving E-Learning by embracing technology, such as SCORM, that allows for shareable content objects to be used and reused within civilian and military education and training Learning Management Systems (LMS) across the World Wide Web.

Abstract:

This thesis investigates a set of non-classical visual receptive field properties observed in the primate brain. Two main phenomena were explored. The first phenomenon was neurons with head-centered visual receptive fields, in which a neuron responds maximally to a visual stimulus in the same head-centered location across all eye positions. The second phenomenon was perisaccadic receptive field dynamics, which involves a range of experimentally observed response behaviours of an eye-centered neuron associated with the advent of a saccade that relocates the neuron's receptive field. For each of these two phenomena, a hypothesis was proposed for how a neural circuit with a suitable initial architecture and synaptic learning rules could, when subjected to visually-guided training, develop the receptive field properties in question. Corresponding neural network models were first trained as hypothesized, and subsequently tested in conditions similar to experimental tasks used to interrogate the physiology of the relevant primate neural circuits. The behaviour of the models was compared to neurophysiological observations as a metric for their explanatory power. In both cases the neural network models were in broad agreement with experimental observations, and the operation of these models was studied to shed light on the neural processing behind these neural phenomena in the brain.

Abstract:

A partir da noção sociocognitiva de língua, texto e gênero do discurso, bem como do processo de referenciação (KOCH, 2009b, CORTEZ, 2003; TEDESCO, 2002, RONCARATI, 2010), o presente trabalho tem por objeto de estudo o samba-enredo (ou samba de enredo), cuja origem é o samba, sendo este um ritmo trazido pelos negros africanos escravizados no Brasil. A partir de um corpus formado por 161 letras de samba-enredo (abrangendo um período que se estende de 1954 a 2010) que trazem como tema alguém ou algo relacionado ao universo africano e/ou afro-brasileiro, ou que pelo menos tangenciem a questão da negritude e afrodescendência, desejamos atingir três objetivos no decorrer dessa pesquisa, quais sejam: a) observar como ocorre o processo de referenciação, isto é, como o referente negro (ou outro termo semanticamente próximo) é ativado, reativado ou desativado em 129 cadeias referenciais, que é um construto linguístico-cognitivo relevante para a formação dos sentidos de um texto; b) quantificar a frequência da temática africana e/ou afrodescendente nos sambas selecionados; c) observar com que frequência um SN complexo é utilizado para introduzir uma cadeia referencial, de modo a imprimir uma marca argumentativa na forma de referir escolhida pelos autores do texto Based on the sociocognitive notion of language, text and discourse gender, as well as the process of referentiation (KOCH, 2009b, CORTEZ, 2003; TEDESCO, 2002, RONCARATI, 2010), the present research focuses at samba-enredo (or samba de enredo, a kind of musical poem to be sung during the Samba Schools Parade, in Brazil), which is one of the variations of samba, a musical rhythm brought by African black people from different nations during the slavery centuries in Brazil. We gathered a corpus containing 161 samba-enredo compositions (covering a period that starts in 1954 and ends in 2010). These texts have someone or something that belongs to the African or Afro-Brazilian world, or, at least, they should mention these issues. Thus, it is our aim to achieve three objectives throughout this research: a) to observe how the process of referentiation is unfolded, that is, how the referent negro (black), or any other semantically close word, is activated, reactivated or desactivated in 129 referential chains, which are a relevant linguistic and cognitive construct to the meaning of a text; b) to quantify the frequency of African and/or Afro-Brazilian issues in the selected lyrics; c) to observe how often a complex NP (noun phrase) is used to introduce a referential chain, so that an argumentative mood is impressed on the lexical selection carried out by the writers of the songs

Abstract:

In this thesis I examine Schelling’s construction of symbolic language in §73 of his Philosophie der Kunst. I approach this construction in three ways. First, I compare Schellingian symbolic language to other contemporary theories of the symbol and language (in particular, those of Goethe, Kant and A.W. Schlegel). While Schelling’s theory of symbolic language possesses properties similar to these other theories (the identity of being and meaning, organic wholeness, the co-existence of opposites), I show that it differs in how they are interpreted. Second, I excavate the metaphysical and epistemological principles from Schelling’s philosophy of the period which underlie this theory of language. Three tenets from the Identitätssystem (as it is called) are crucial: formation, quantitative differentiation and construction. They illuminate why Schelling interprets symbolic language very differently to his contemporaries. Third, I consider the theological significance of Schellingian symbolic language. This significance is twofold. First, his theory gives rise to a conception of discourse without reference, and so to the notion of a theology without reference. On this basis, Schelling criticises Christian theology for remaining too concerned with referring to God, when what is at stake is rather the degree of intensity to which it produces God. Theology therefore stands in need of reformation. Second, the way in which theology is utilised by Schelling in order to construct symbolic language in §73 of the Philosophie der Kunst itself provides a model for reformed theological practice. I argue that Schelling conceives of traditional theology as material for intensifying the production of God. In this way, an ‘absolute theology’ is engendered which has no concern for reference or for the integrity of the theological tradition.

Abstract:

The International Linear Collider (ILC) aims to collide electrons and positrons with a centre of mass energy of 500GeV and a luminosity of 2×1034 cm−2 s−1. To achieve this luminosity, the nominal final emittance of the electron and positron beams have to be below 10μm.rad horizontally and 0.04μm.rad vertically. To prevent the emittance from becoming too large, the main linacs will require alignment at an unprecedented level. The ILC main linacs will be aligned with respect to a reference network which runs along the entire length of the tunnel. The Linear Collider Alignment and Survey (LiCAS) Rapid Tunnel Reference Surveyor (RTRS) is the prototype of a device proposed to survey the ILC reference network. The LiCAS RTRS has several measurement systems; its Frequency Scanning Interferometry (FSI) measurement system is studied in this thesis. The FSI system has three distinct sub-systems: the reference interferometers, the external FSI measurement system and the internal FSI measurement system. The errors on the length of the reference interferometers are shown to be of the order of 1.1μm (0.3ppm). The external FSI measurement system is shown to measure distances close to 0.42m with errors of &pm;1.9μm stat &pm;0.16μm syst and the internal FSI measurement system is shown to measure distances close to 4.2m with errors of &pm;0.24μm stat &pm;1.6μm syst. A survey of the ILC reference network using laser trackers is simulated without taking account of systematic measurement errors from refraction in the tunnel air. The simulated networks are used to misalign the simulated accelerators in Dispersion Matched Steering (DMS) simulations. The DMS simulations show that only 30% of the simulated accelerators produce an acceptable final corrected vertical emittance. It is further shown that the introduction of long range distance measurements between primary reference markers (PRMs) using GPS, reduces the long range error growth in the network, and that 95% of simulated accelerators give acceptable performance. A simplified network simulation model, which is capable of simulating reference networks surveyed by conventional and novel devices, is produced and compares favorably to full simulations.

Abstract:

Les langages de programmation orientés-objet dynamiquement typés ne peuvent pas fournir d’informations de type avant l'exécution. Deux de leurs principaux avantages sont qu'ils permettent le prototypage rapide et l'intégration de modifications lors de l'exécution. La capacité des langages dynamiquement typés accepter les changements du programme lors de son exécution et en l'absence d’informations de type, condamne les approches de sécurité classiques à l'échec.Contrôler les références des objets et des graphes d'objets est indispensable pour construire des systèmes sécurisés. Les approches existantes sont généralement basées sur un système de type statique et ne peuvent pas être appliquées aux langages dynamiquement typés.Cette thèse défend que:Dans le contexte des langages de programmation orientés-objet dynamiquement typés, réifier les références, contrôler leur comportement, et isoler l'état des objets par le biais de telles références, est un moyen pratique de contrôler les références.Cette thèse apporte cinq contributions:- Nous proposons la notion de dynamic read-only objects (DRO) comme un changement particulier (read-only) de comportement au niveau des références; - Nous généralisons le modèle DRO pour permettre des changements de comportement plus génériques et nous étendons l'environnement de programmation et le langage Pharo avec des Handles, qui sont des références avec la possibilité de changer le comportement des objets référencés;- Nous définissons le terme de Metahandle pour offrir flexibilité et adaptabilité aux références contrôlées; - Nous proposons la notion de SHandle, pour isoler les effets de bord au niveau des références;- Et enfin, nous décrivons formellement les modèles Handle et SHandle pour représenter et expliquer leur sémantique.Comme validation de notre thèse nous avons mis en place trois approches liées à la sécurité en utilisant nos modèles. En outre, nous avons étendu la machine virtuelle Pharo pour supporter les Handles, Metahandles et SHandles Dynamically-typed object-oriented programming languages do not provide type information until runtime. Two of their main advantages are that they allow fast prototyping and integrating changes at runtime. The ability of dynamically-typed languages to support program changes at runtime and the lack of type information doom the classic security approaches to failure. Controlling references to single objects and to graphs of objects is essential to build secure systems. Existing approaches are commonly based on static type system and cannot be applied to dynamically-typed languages.This thesis argue that: In the context of dynamically-typed languages, reifying references, controlling behavior, and isolating state via such references, is a practical way to control references.This thesis makes five contributions: - We propose dynamic read-only objects (DRO) as one kind of adaptation of behavioral change at reference-level. - We generalize the DRO model to enable more generic behavioral changes. We extend the Pharo programming environment and language with Handles, that are first-class references with the ability to change the behavior of referenced objects. - We define Metahandle to offer flexibility and adaptability to controlled references. - We propose SHandle, an extension of the Handle model to isolate side effects at the level of references. - And finally, we formalize the Handles and SHandle models to represent and explain their semantics.As vlidation of our thesis we have implemented three approaches relevant to securing system using our model. In addition, as proof of concept we extended the Pharo virtual machine to support Handles, Metahandles and SHandles

Abstract:

Den säkerhetspolitiska debatten har under de senaste åren tillvaratagit ett bredare perspektiv av hot och risker. Undersökningen tar sin utgångspunkt i frågan om i vilken utsträckning detta kommit till uttryck i svenska försvarspropositioner? Undersökningen kartlägger likheter och skillnader i tre försvarspropositioners uttryck av hot och säkerhet relaterat till det vidgade säkerhetsbegreppet under perioden 1982-2009. Vid kartläggningen undersöker jag med hjälp av Barry Buzan m.fl. analysramverk för det vidgade säkerhetsbegreppet vilka säkerhetspolitiska värden som uttrycktes vara viktiga att säkerställa. Undersökningen kartlägger även hotbilderna som uppfattades mot dessa värden och inom vilka arenor deras säkerhet bedömdes kunna säkerställas.Analysen påvisar olikheter i de tre försvarspropositionernas säkerhetspolitiska uttryck. 1982 års försvarsproposition fokuserar på nationella säkerhetspolitiska värden som säkerställdes inom totalförsvarets ram. De följande försvarspropositionerna indikerar en förändring till förmån för regionala värden och gemensam säkerhet. Analysen påvisar även en radikal förändring av de uppfattade hotbildernas karaktär. The recent security policy debate has included a broader view of threats and risks. This study is based on the question of to what extent this was reflected in the Swedish defence bills?This study aims to identify similarities and differences regarding expressions of threat and security related to the broader concept of security in three defence bills over the period of 1982-2009. By use of the analytical framework of Mr Barry Buzan, I aim to make a survey of the expressed values of security, their perceived threats and the arenas in which their security were to be guaranteed.The analysis indicates diversities regarding security policy expressions. The defence bill of 1982 focuses on national values, safeguarded within the framework of Total Defence. The following defence bills indicate a change in the perceived nature of the threats and in favour of regional values and common security.

Abstract:

Stationsetablering innebär bestämning av ett mätinstruments fysiska läge och orienterad riktning. I dagens bygg- och anläggningsbransch används nästan uteslutande fri station för att etablera en stationspunkt för mätningar. På en byggplats är tillgången till referensobjekt ofta begränsad. Instrumentets placering blir därför en kompromiss mellan tillgång till referensobjekt och tillgång till den plats där inmätning respektive utsättning skall ske. Denna kompromiss ger upphov till skiftande geometriska konfigurationer hos referensobjekten, vilka påverkar mätresultatet. Studiens syfte är att undersöka om simuleringar av fria stationsuppställningar i Svensk Byggnadsgeodesis (SBG:s) programvara Geo verifieras av fältmätningar och efterföljande beräkningar av osäkerhetsparametrar orsakade av konfiguration och mätta längder och riktningar. Delmål var att etablera ett testnät för att sedan genomföra simulering och fältmätning av fri stationsetablering mot. Analysen av fri stationsuppställning innefattade endast simulering och fältmätning i plan, med parametrarna X, Y och riktning. I samtliga konfigurationer verifieras simuleringarna av fältmätningarna genom att redovisade osäkerhetsellipser, till form och utbredning, överensstämmer. Detta innebär att genom simulering i SBG Geo kan svagheter i konfigurationer upptäckas och undvikas vid fältmätning, vilket är både tids- och resurssparande. Studiens slutsats är; Simulera mera. Simulering i SBG Geo visar god överensstämmelse med fältmätning och är där med ett effektivt planeringsverktyg för mätning samt att vid etablering av fri station bör referensobjekten placeras så att stationspunkten interpoleras för lägst osäkerhet. Faktorer att beakta vid fri station är, enligt studien: konfigurationen, mätningarnas kvalitet och att tillräcklig kontrollerbarhet (k-tal) föreligger Station setup involves determination of the measuring instruments physical location and orientation. In today's construction industry free station is almost exclusively used to establish a station point for measurements. On a construction site, access to reference objects is often limited. The instruments placement therefore becomes a compromise between access to the reference objects and access to the site where surveying will take place. This compromise results in varying geometric configurations of the reference objects, which affect the results of the survey. This study aims to investigate whether the simulations of free station setups in Svensk Byggnadsgeodesis ( SBG's ) software Geo is verified by field measurements and subsequent calculations of uncertainty parameters caused by configuration and surveyed distances and directions. One objective of this study was to establish a test network of reference objects, which simulation and field measurement of free station were established against. The analysis of free station setup included only simulation and field measurement of plane surveying, with the parameters X, Y and direction. In all configurations, the simulations were verified by the field measurements by consistent corresponding of the shape of the error ellipses. This means that by simulation of SBG Geo, weaknesses in configurations can be detected and avoided during field survey, which saves both time and resources. Factors to consider when establishing free station is, according to the study: configuration, quality of the measurements and sufficient controllability (K-tal). The study concludes; simulate more. Simulation in SBG Geo show good representation of field measurements and is therefore an effective planning tool for field surveying. When establishing free station reference objects should be positioned so that the station point is interpolated for the lowest uncertainty

Abstract:

The core of the thesis investigates the role of education in the engendering of cultural change and leadership among a select group of a powerful 'first generation' of Arab women; specifically, the role of dual educational/cultural experiences, both Arab and Western. The broader aim of the study is to analyze the merging of cultural traditionalism and modernity and how dual education has enhanced the ability of women, especially Arab women, to become leaders in their professional careers, and within their respective communities, whilst still maintaining strong ties to their culture, religion and traditions, albeit to varying degrees. The writer has chosen to investigate the association between cultural identity and educational experience of elite educated Arab women, through a small sample, who have had exposure to both Western and Arab educational systems at different points in their lives. The researcher's heritage has led to a fundamental ideological interest in the coexistence of traditionalism and modernisation and whether the two can complement one another. There are now a significant number of Arab women who have had the privilege of education and exposure to the two types of systems. Yet, gender constraints and predefined gender roles still very much dictate the socio-cultural contexts in which such women have to operate. The patriarchal 'system' is omnipresent in the West as well as in the Arab world. The challenges the writer has faced even as a 'Western' Arab to reconcile tradition and intellectual and educational exposure has served as a greater impetus for this investigation. The investigation and the intent of this thesis as described above, is to test the preliminary hypothesis that, in the context of elite Arab women, their exposure to both West and Arab educational cultures is germane to their potential for influencing female professional development. How their educational experiences have influenced their own identities and their ability to adhere to the gender roles prescribed is of significant interest. What influence has such education had on these women's prospects for instituting and pioneering change in their respective societies and professions? Is the synergy of certain aspects of modernity and tradition possible? The general conclusion is that it is.

Abstract:

An investigation was conducted into gall induction in the leaves of Salix fragilis L. var. russelliana (Sm.) Koch by Pontania proxima (Lepeletier) (Hymenoptera: Tenthredinidae). The work was divided into four parts:- a) Reviews of the available literature were undertaken on: hypotheses concerning cecidogenesis of galls initiated by insects, the history of cecidology as it related to galls formed by insects, the ontogeny and morphology of galls produced by sawflies, ecological aspects of gall biology and the effects of galling on the host plant. b) Methods of rearing both insect and host were established; these resulted in an extension of the insect's flight period from five to eight months with three broods per year instead of the usual two. Further work established the topological specificity of oviposition. Preliminary studies were completed on the tissue culture of Salix leaf-disc explants and the fusion of protoplasts released from normal and galled tissue. c) Using light and electron microscopy, a study was made of the reproductive system and associated glands of Pontania proxima females, together with the first stages of the procecidium they initiated. Using these techniques, no microorganisms, viral or otherwise, were observed in the gall, in the lumina of the reproductive system and associated glands or in surrounding tissues of the insect. Evidence for a secretory role for the lateral oviducts was found. A structure termed the vaginal valve was described and it was hypothesized that this functioned to separate the fluids produced by the accessory glands from the contents of the oviduct, until oviposition. In the plant, it was observed that the gall effect was limited and that the presence of an egg or larva was not required for the formation of a procecidium. Gall growth was mainly due to periclinal divisions of the provascular tissues of the leaf. d) A bioassay, based on microinjection techniques, was developed .This demonstrated that the cecidogen was contained in the colleterial fluid produced by the accessory glands. Further analysis showed that the cecidogen had a molecular weight of less that 3 kDa.

Abstract:

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES Every act of language results from a play between the implicit and the explicit (CHARAUDEAU, 2008). This phenomenon is born of specific discourse situations, which are carried out from the production and interpretation processes, and intrinsic to the social, historical and cultural context (BAKHTIN, 2003 [1979]). Communication has evolved in its most primitive form, perfecting itself and, consequently, passing through the invention of various technologies, until arriving at new media mechanisms interwoven by the digital world and developed in the contemporary world (from cave paintings to wood / clay plates, Scrolls, codex, books, computers, Tablets etc.). This moment in which this hybridization of languages gains a new dimension (BRAGA, 2013). This resizing broadens the ways of communicating and, consequently, allows the emergence of new textual genres that operate according to the cultural context (MARCUSCHI, 2008). The meme is a symbolic genre with respect to the digital environment today. Among so many others that are part of the research universe, it is important that this genre is more explored, since it alludes to textual configurations and sociodiscursive practices that reflect the individual's culture today. In this perspective, and based on Lévy (1999), Shifman (2014), Mondada and Dubois (2003), Cavalcante and Custódio Filho (2010), Cavalcante (2015), Koch and Elias (2016b), Kress and Van Leuween (2001), Xavier (2009), among others of equal importance, we seek, in this research, to analyze how the objects of discourse are (re) elaborated, in the digital meme genre, during the interaction of the subjects in the construction of the meanings of multimodal texts in the light of sociocognitivism and under the current perspective of the studies of Text Linguistics in interface with the theory of multimodality. To this end, From the theory of referencing and a multimodal view, that the making of the objects of speech happens also under multisemiotic textual configuration, and in the genre meme is, in most cases, recurrent in virtual environments, under a multimodal representation, encapsulating information and/or portions of texts, insofar as they assume some functions of indicating criticism and ideological positions or, also, creating humor effects. Thus, we attribute to this research qualitative nature because we consider its production in an environment of collective intelligence and rapid sharing of this information, that is, a high degree of interaction between the subjects. The corpora used, digital memes, were mostly selected from the memes museum website, taking as reference that the social universe is culturally shared among the interacting agents of the sociocommunicative process. Todo ato de linguagem resulta de um jogo entre o implícito e o explícito (CHARAUDEAU, 2008). Esse fenômeno nasce de situações de discurso específicas, as quais se realizam a partir dos processos de produção e de interpretação, e intrínsecas ao contexto social, histórico e cultural (BAKHTIN, 2003[1979]). A comunicação tem evoluído da sua forma mais primitiva, aperfeiçoando-se e, consequentemente, passando pela invenção de várias tecnologias, até chegar a novos mecanismos midiáticos entremeados pelo mundo digital e desenvolvidos na contemporaneidade (das pinturas rupestres às placas de madeira/argila, aos pergaminhos, ao códex, aos livros, aos computadores, aos tablets etc.). Momento este em que essa hibridização de linguagens ganha uma nova dimensão (BRAGA, 2013). Esse redimensionamento amplia as formas de comunicar e, consequentemente, permite o surgimento de novos gêneros textuais que operam em função do contexto cultural (MARCUSCHI, 2008). O meme é um gênero simbólico no que diz respeito ao ambiente digital na atualidade. Entre tantos outros que fazem parte do universo da pesquisa, é importante que este gênero seja mais explorado, pois alude a configurações textuais e práticas sociodiscursivas que refletem a cultura do indivíduo na atualidade. Nessa perspectiva, e com base em Lévy (1999), Shifman (2014), Mondada e Dubois (2003), Cavalcante e Custódio Filho (2010), Cavalcante (2015), Koch e Elias (2016b), Kress e Van Leuween (2001), Xavier (2009), dentre outros de igual importância, buscamos, nesta pesquisa, analisar como os objetos de discurso são (re)elaborados, no gênero meme digital, durante a interação dos sujeitos na construção dos sentidos de textos multimodais à luz do sociocognitivismo e sob a perspectiva atual dos estudos da Linguística de Texto em interface com a teoria da multimodalidade. Para tanto, defendemos, a partir da teoria da referenciação e de um olhar multimodal, que a feitura dos objetos de discurso acontece também sob configuração textual multissemiótica, e no gênero meme é, na maioria das vezes, recorrente em meios virtuais, sob uma representação multimodal, encapsulando informações e/ou porções de textos, na medida em que assumem algumas funções de indicação de críticas e de posicionamentos ideológicos ou, ainda, criação de efeitos de humor. Desse modo, atribuímos a esta pesquisa natureza qualitativa porque consideramos sua produção em ambiente de inteligência coletiva e de rápido compartilhamento dessas informações, isto é, alto grau de interação entre os sujeitos. Os corpora utilizados, memes digitais, foram mormente selecionados do site museu de memes, tomando por referência que o universo social é culturalmente compartilhado entre os interactantes do processo sociocomunicativo.

Abstract:

The nature of trials, tests, and temptation in the Epistle of James has been extensively debated in New Testament scholarship. However, scholarship has underexamined the tension between the author’s mitigation of divine agency in testing ( Jas 1:13–14) and the author’s appeal to well-known biblical testing narratives such as the creation account (1:15– 18), the Binding of Isaac ( Jas 2:21–24), and the Trials of Job ( Jas 5:9–11). is juxtaposition between the author’s theological apologetic and his biblical hermeneutic has the potential to reveal either the author’s theological incoherence or his rhetorical and hermeneutical creativity. With these tensions of divine agency and biblical interpretation in mind, this dissertation compares the Epistle of James against other examples of ancient Jewish interpretation, interrogating two points of contact in each Jewish work: their portrayals of the cosmic drama of testing, and their resulting biblical hermeneutic. The dissertation assembles a spectrum of positions on how the divine, satanic, and human roles of testing vary from author to author. These variations of the dramatis personae of the cosmic drama exercise a direct influence on the reception and interpretation of the biblical testing narratives. When the Epistle of James is examined in a similar light, it reveals a cosmic drama especially dependent on the metaphor of the divine law court. Within this cosmic drama, God stands as righteous judge, and in the place of divine prosecutor stand the cosmic forces indicting both divine integrity and human religious loyalty. These cosmic and human roles have a direct impact on James’ reading of biblical testing narratives. Utilising an intra-canonical hermeneutic similar to that found in Rewritten Bible literature, the Epistle appeals to a constructed ‘Jobraham’ narrative in which the Job stories mitigate divine agency in biblical trials such as those of Abraham, and Abraham’s celebrated patience rehabilitates Job’s rebellious response to trial. In conclusion, by closely examining the broader exegetical discourses of ancient Judaism, this project sheds new light on how the Epistle of James responds to theological tensions within its religious community through a hermeneutical application of the dominant biblical narratives of Job’s cosmic framework and Abraham’s human perfection.

Abstract:

The research field addressed by this thesis is the commedia dell'arte and its iconography in the period preceding Callot's Balli di Sfessania engravings of c. 1621. Its main aim is to provide a broad overview of the surviving early pictures in order to contribute towards a more detailed understanding of the history of the commedia deH'arte in the opening decades of its existence, 1560-1620, by using late renaissance pictures as a documentary source. My research method has three main steps. These are firstly, the identification of relevant pictures, on the basis of a detailed understanding of the early history of the commedia dell'arte, and taking a deliberately inclusive approach; secondly, the classification of such pictures according to art-historical methods, in order to associate them with specific named artists so that they can be placed in the context of an oeuvre and place of production; thirdly, interpretation of their theatrical content. Integral to the thesis are the 340 plates. Many feature pictures which were anonymous or implausibly attributed, and unknown to theatre historians, before they appeared here or in my publications. My inclusive approach has contributed towards the marked rehabilitation of carnival pictures which is evident in the most recent scholarship in this area. My new discoveries, and attributions and re-attributions of some of the 340 plates, summarized in the plate list, have enabled me to identify significant bodies of commedia-related pictures by a number of named late renaissance artists not previously associated with theatre iconography, and provide a broad overview of the early stock types, their costumes and settings; contributions which are stimulating further research in this area. Section I summarises the rise and spread of professional acting in sixteenth century Italy, some forerunners of the commedia dell'arte, and its early stock types. It also presents new documentary material, discovered in the course of my archival researches, which is relevant to the earliest commedia performance for which a comprehensive description survives, staged in Munich in 1568. Section II presents art-historical analyses of three groups of prints in Stockholm, and six paintings which are the subject of an article published in 1943. It also presents an overview of a large group of Flemish pictures whose relation to two Italian prints demonstrates the progressive stereotyping of commedia-related motifs which was already occurring around 1600. Section III offers theatrical interpretations of the pictures, concentrating on scenery, set and stages; actresses; a selection of stock characters, including Harlequin, Zanni and Pantalone, and also some less wellknown figures such as tedescos and matachins; and multiple and serial images. The renaissance Italian comedians' multiple roots in amateur humanist comedy, professional entertainment and popular carnival ritual gave them their early creativity and wide appeal, and left their mark on the iconography which, by the seventeenth century, like the commedia dell'arte itself, was, for the most part, settling into a predictable routine based on precedents and conventions.

Abstract:

In high-diversity populations, a complete accounting of de novo mutations can be difficult to obtain. Most analyses involve identifying such mutations by sequencing pedigrees on second-generation sequencing platforms and aligning the short reads to a reference assembly, the genomic sequence of a canonical member (or members) of a species. Often, large regions of the genomes under study may be greatly diverged from the reference sequence, or not represented at all (e.g. the HLA, antigenic genes, or other regions under balancing selective pressure). If the haplotypic background upon which a mutation occurs is absent, events can easily be missed (as reads have nowhere to align) and false-positives may abound (as the software forces the reads to align elsewhere). This thesis presents a novel method for de novo mutation discovery and allele identification. Rather than relying on alignment, our method is based on the de novo assembly of short-read sequence data using a multi-color de Bruijn graph. In this data structure, each sample is assigned a unique index (or "color"), reads from each sample are decomposed into smaller subsequences of length k (or "kmers"), and color-specific adjacency information between kmers is recorded. Mutations can be discovered in the graph itself by searching for characteristic motifs (e.g. a "bubble motifs", indicative of a SNP or indel, and "linear motifs" indicative of allelic and non-allelic recombination). De novo mutations differ from inherited mutations in that the kmers spanning the variant allele are absent in the parents; in a sense, they facilitate their own discovery by generating "novel" sequence. We exploit this fact to limit processing of the graph to only those regions containing these novel kmers. We verified our approach using simulations, validation, and visualization. On the simulations, we developed genome and read generation software driven by empirical distributions computed from real data to emit genomes with realistic features: recombinations, de novo variants, read fragment sizes, sequencing errors, and coverage profiles. In 20 artifical samples, we determined our sensitivity and specificity for novel kmer recovery to be approximately 98% and 100% at worst, respectively. Not every novel stretch can be reconstituted as a variant, owing to errors and homology in the graph. In simulations, our false discovery rate was 10% for "bubble" events and 12% for "linear" events. On validation, we obtained a high-quality draft assembly for a single P. falciparum child using a third-generation sequencing platform. We discovered three de novo events in the draft assembly, all three of which are recapitulated in our calls on the second-generation sequencing data for the same sample; no false-positives are present. On visualization, we developed an interactive web application capable of rendering a multi-color subgraph that assists in visually distinguishing between true variation and sequencing artifacts. We applied our caller to real datasets: 115 progeny across four previously analyzed experimental crosses of Plasmodium falciparum. We demonstrate our ability to access subtelomeric compartments of the genome, regions harboring antigenic genes under tremendous selective pressure, thus highly divergent between geographically distinct isolates and routinely masked and ignored in reference-based analyses. We also show our caller's ability to recover an important form of structural de novo variation: non-allelic homologous recombination (NAHR) events, an important mechanism for the pathogen to diversify its own antigenic repertoire. We demonstrate our ability to recover the few events in these samples known to exist, and overturn some previous findings indicating exchanges between "core" (non-subtelomeric) genes. We compute the SNP mutation rate to be approximately 2.91 per sample, insertion and deletion mutation rates to be 0.55 and 1.04 per sample, respectively, multi-nucleotide polymorphisms to be 0.72 per sample, and NAHR events to be 0.33 per sample. These findings are consistent across crosses. Finally, we investigated our method's scaling capabilities by processing a quintet of previously analyzed Pan troglodytes verus (western chimpanzee) samples. The genome of the chimpanzee is two orders of magnitude larger than the malaria parasite's (3, 300 Mbp versus 23 Mbp), diploid rather than haploid, poorly assembled, and the read dataset is lower coverage (20x versus 120x). Comparing to Sequenom validation data as well as visual validation, our sensitivity is expectedly low. However, this can be attributed to overaggressiveness in data cleaning applied by the de novo assembler atop which our software is built. We discuss the precise changes that would likely need to be made in future work to adapt our method to low-coverage samples.

Abstract:

This thesis is a context-sensitive study of key epistemological commitments and concerns presented in Philo’s two series of exegetical writings. The major conclusion advanced in this thesis is that two theological epistemologies, distinct yet related, can be detected among these writings. The first epistemology is specific to the Allegorical Commentary. The second epistemology is specific to the ‘Exposition of the Law.’ The epistemology of the Allegorical Commentary reflects a threefold conviction: the sovereignty of God, the creaturely contingency of the human mind and its inescapable limitations. In conversation with key epistemological notions of his day, Philo develops this threefold conviction in exegetical discourses that are grounded in Pentateuchal texts portraying the God of Moses as both possessing epistemic authority and aiding the aspiring mind to gain purification and perfection in the knowledge of God. Guided by this threefold conviction, Philo enlists key metaphors of his day – initiation into divine mysteries and divine inspiration, among others –in order to capture something of the essence of Moses’ twofold way of ascending to the divine, an approach which requires at times the enhancement of human reason and at other times the eviction of human reason. The epistemology of the ‘Exposition’ reflects Philo’s understanding of the Pentateuch as a perfect whole partitioned into three distinct yet inseverable parts. Philo’s knowledge discourses in the ‘creation’ part of the ‘Exposition’ reflect two primary movements of thought. The first is heavily invested with a Platonic reading of Genesis 1.27 while the second invests Genesis 2.7 with a mixture of Platonic and Stoic notions of human transformation and well-being. Philo’s discourses in the ‘patriarchs’ segment reflect an interest in portraying the three great patriarchs as exemplars of the virtues of instruction (Abraham), nature (Isaac), and practice (Jacob) which featured prominently in Greek models of education. In the ‘Moses’ segment of the ‘Exposition,’ many of Philo’s discourses on knowledge are marked by an interest in presenting Moses as the ideal king, lawgiver, prophet and priest who surpasses Plato’s paradigm of the philosopher-king. In keeping with this view, Philo insists that the written laws of Moses represent the perfect counterpart to the unwritten law of nature. The life and laws of Moses serve as the paradigm for Philo to understand his own experiences of noetic ascent and exhort readers to cultivate similar aspirational notions and practices.
