"Girls who kick butt" : a cognitive interpretation of Tamora Pierce's adolescent feminist fantasyDay, Kathryn Dawn January 2018 (has links)
Recent empirical evidence supports the theoretical stance that fiction provides vicarious experiences of imagined spaces and situations that can help shape our perceptions of the real world, our social others, and the self. The implications for this are especially interesting for adolescents, as their brains undergo a restructuring during puberty, making them more responsive to change in executive function and social cognition. Few scholars have yet addressed how texts instruct young readers in how to use their developing cognition to assess characters' emotions and behavior, and how fiction can potentially affect these readers' cognitive and emotional development. This thesis analyzes the concept that potential adolescent readers can engage with a novel's characters' thoughts and behaviors by using their improving cognitive abilities to transmute what is on the page into real-life coping strategies. This phenomenon is especially compelling when considering the potential impact empowered female characters could have on adolescent girl readers, since their malleable brain around puberty makes them more receptive to accepting ideas - such as a person's gender not being a limitation. I examine what the primary texts themselves offer to potential readers, and analyze certain aspects of the texts that could be linked to potential readers' cognitive and affective engagement. The primary texts I have chosen are Tamora Pierce's two narrative quartets (The Song of the Lioness and Protector of the Small) that deal with characters from the fictional land of Tortall, as they focus closely on female characters in fantasy realms who are breaking gendered stereotypes by training to become knights. Pierce's books are representative of this adolescent feminist fantasy. I extrapolate that findings from this thesis will be applicable to other kinds of adolescent feminist fantasy texts; namely, that adolescent feminist fantasy fiction can beneficially change potential readers behavior and cognition.

Estimation, validation et identification des modèles ARMA faibles multivariésBoubacar Mainassara, Yacouba 28 November 2009 (has links) (PDF)
Dans cette thèse nous élargissons le champ d'application des modèles ARMA (AutoRegressive Moving-Average) vectoriels en considérant des termes d'erreur non corrélés mais qui peuvent contenir des dépendances non linéaires. Ces modèles sont appelés des ARMA faibles vectoriels et permettent de traiter des processus qui peuvent avoir des dynamiques non linéaires très générales. Par opposition, nous appelons ARMA forts les modèles utilisés habituellement dans la littérature dans lesquels le terme d'erreur est supposé être un bruit iid. Les modèles ARMA faibles étant en particulier denses dans l'ensemble des processus stationnaires réguliers, ils sont bien plus généraux que les modèles ARMA forts. Le problème qui nous préoccupera sera l'analyse statistique des modèles ARMA faibles vectoriels. Plus précisément, nous étudions les problèmes d'estimation et de validation. Dans un premier temps, nous étudions les propriétés asymptotiques de l'estimateur du quasi-maximum de vraisemblance et de l'estimateur des moindres carrés. La matrice de variance asymptotique de ces estimateurs est d'une forme "sandwich", et peut être très différente de la variance asymptotique obtenue dans le cas fort. Ensuite, nous accordons une attention particulière aux problèmes de validation. Dans un premier temps, en proposant des versions modifiées des tests de Wald, du multiplicateur de Lagrange et du rapport de vraisemblance pour tester des restrictions linéaires sur les paramètres de modèles ARMA faibles vectoriels. En second, nous nous intéressons aux tests fondés sur les résidus, qui ont pour objet de vérifier que les résidus des modèles estimés sont bien des estimations de bruits blancs. Plus particulièrement, nous nous intéressons aux tests portmanteau, aussi appelés tests d'autocorrélation. Nous montrons que la distribution asymptotique des autocorrelations résiduelles est normalement distribuée avec une matrice de covariance différente du cas fort (c'est-à-dire sous les hypothèses iid sur le bruit). Nous en déduisons le comportement asymptotique des statistiques portmanteau. Dans le cadre standard d'un ARMA fort, il est connu que la distribution asymptotique des tests portmanteau est correctement approximée par un chi-deux. Dans le cas général, nous montrons que cette distribution asymptotique est celle d'une somme pondérée de chi-deux. Cette distribution peut être très différente de l'approximation chi-deux usuelle du cas fort. Nous proposons donc des tests portmanteau modifiés pour tester l'adéquation de modèles ARMA faibles vectoriels. Enfin, nous nous sommes intéressés aux choix des modèles ARMA faibles vectoriels fondé sur la minimisation d'un critère d'information, notamment celui introduit par Akaike (AIC). Avec ce critère, on tente de donner une approximation de la distance (souvent appelée information de Kullback-Leibler) entre la vraie loi des observations (inconnue) et la loi du modèle estimé. Nous verrons que le critère corrigé (AICc) dans le cadre des modèles ARMA faibles vectoriels peut, là aussi, être très différent du cas fort.

Conception de circuits WLAN 5 GHZ à résonateurs BAW-FBAR intégrés : oscillateurs et amplificateurs filtrantsAissi, Mohammed 02 June 2006 (has links) (PDF)
Les travaux de recherche présentés dans cette thèse consistent principalement en la conception de fonctions intégrées radiofréquences BiCMOS SiGe exploitant des résonateurs à ondes acoustiques de volume FBAR. Contrairement aux techniques actuelles rencontrées dans l'industrie qui consistent à réaliser des filtres et des résonateurs discrets et à les associer par la suite avec les circuits actifs des émetteurs-récepteurs au niveau du boîtier, nos résonateurs sont directement réalisés sur le substrat silicium des circuits actifs RF par une technique appelée intégration " above-IC ". Avec cette méthode d'intégration, les parasites et la modélisation associés aux microsoudures (Wire Bonding) sont éliminés. Elle permet aussi de se passer des circuits d'interface et d'adaptation nécessaires dans le cas de filtres RF discrets. Ceci permet de réduire considérablement la consommation et le volume des systèmes. Des amplificateurs faible bruit filtrants et des oscillateurs visant le standard WLAN IEEE 802.11a ont ainsi été implantés en utilisant cette technique d'intégration "above IC". Les circuits obtenus sont très compacts, et leurs performances, notamment celles des oscillateurs, sont à l'état de l'art. Par ailleurs, des amplificateurs faible bruit et des VCO LC SiGe intégrés pour application WLAN 5GHz sont également présentés et leurs techniques d'optimisation sont données.

Towards a comparative evaluation of text-based specification formalisms and diagrammatic notationsMoremedi, Kobamelo 19 January 2017 (has links)
Specification plays a vital role in software engineering to facilitate the development of highly dependable software. The importance of specification in software development is to serve, amongst others, as a communication tool for stakeholders in the software project. The specification also adds to the understanding of operations, and describes the properties of a system. Various techniques may be used for specification work.
Z is a formal specification language that is based on a strongly-typed fragment of Zermelo-Fraenkel set theory and first-order logic to provide for precise and unambiguous specifications. Z uses mathematical notation to build abstract data, which is necessary for a specification. The role of abstraction is to describe what the system does without prescribing how it should be done.
Diagrams, on the other hand, have also been used in various areas, and in software engineering they could be used to add a visual component to software specifications. It is plausible that diagrams may also be used to reason in a semi-formal way about the properties of a specification. Many diagrammatic languages are based on contours and set theory. Examples of these languages are Euler-, Spider-, Venn- and Pierce diagrams. Euler diagrams form the foundation of most diagrams that are based on closed curves.

The purpose of this research is to demonstrate the extent to which diagrams can be used to represent a Z specification. A case study is used to transform the specification modelled with Z language into a diagrammatic specification. Euler, spider, Venn and Pierce diagrams are combined for this purpose, to form one diagrammatic notation that is used to transform a Z specification / School of Computing / M. Sc.

An Analysis of the Interrelationship Between the Oregon School Law of 1922, the Press of Oregon, the Election of Walter Pierce and the Ku Klux KlanHuffman, Robin 01 January 1974 (has links)
Oregon in 1922 was the scene of significant Ku Klux Klan activity. This thesis examines the interrelationship of the Klan, the press of Oregon, the gubernatorial race of that year and the passage of the Compulsory School Act. In addition, one chapter covers the ultimate fate of the Compulsory School Act in the courts.
Specific material in this thesis is derived principally from newspapers and periodicals of the time, although general sources on the Ku Klux Klan were utilized for the broader discussions of the situations.
The existence of the Ku Klux Klan in Oregon in 1922 directly affected both the passage of the Compulsory School Act and the election of Walter Pierce. The roles of the state’s newspapers were mixed. Two were quite outspoken on the issues of the Klan and the Compulsory School act, while most took less forthright stands. It was in the United States Supreme Court, however, that the final decision on the compulsory School Act was made.

Fantasy: The Literature of Repetition / Fantasy: The Literature of Repetition – An Examination of Lady Éowyn, Hermione Granger, and Keladry of MindelanSattler, Emily C. January 2016 (has links)
This project explores the narrative arcs of strong female characters in Young Adult (YA) fantasy literature. Taking up Rosemary Jackson’s assertion that fantasy literature can ‘subvert patriarchal society,’ this thesis examines the fantasy ‘legacy code’ of strong and subversive female characters who settle into a stereotypical performance of gender after finding fulfillment in the heteronormative roles of lover, wife, and mother. This pattern is exemplified by Lady Éowyn of J.R.R. Tolkien’s The Two Towers (1954) and The Return of the King (1955), and reproduced by Hermione Granger of J.K. Rowling’s Harry Potter series – consisting of Harry Potter and the Philosopher’s Stone (1997), Harry Potter and the Chamber of Secrets (1998), Harry Potter and the Prisoner of Azkaban (1999), Harry Potter and the Goblet of Fire (2000), Harry Potter and the Order of the Phoenix (2003), Harry Potter and the Half-Blood Prince (2005), and Harry Potter and the Deathly Hallows (2007). In contrast Keladry of Mindelan in Tamora Pierce’s Protector of the Small series – consisting of First Test (1999), Page (2000), Squire (2001), and Lady Knight (2002) – demonstrates the impact ‘refactoring’ fantasy ‘legacy code’ has on the narrative conclusions of female characters. Using Judith Butler’s theory on the performative nature of gender and building on Farah Mendlesohn’s computer programming analogy of ‘legacy code,’ this thesis illustrates the ways in which fantasy literature often fails to be the literature of subversion Jackson envisions, and demonstrates how refactoring aspects of a female character’s narrative exemplifies subversive narrative conclusions for young adult readers of fantasy literature. / Thesis / Master of Arts (MA) / This thesis examines the ways in which a heteronormative ‘legacy code’ – exemplified by Lady Éowyn in J.R.R. Tolkien’s Lord of the Rings – has been perpetuated in literature marketed towards young adult readers by Hermione Granger in J.K. Rowling’s Harry Potter series and ‘refactored’ by Keladry of Mindelan in Tamora Pierce’s Protector of the Small series. Starting with Rosemary Jackson’s analysis of fantasy literature as a genre with subversive potential and with Judith Butler’s assertion that gender is performative, this thesis analyses the narrative arcs of Éowyn, Hermione, and Kel and demonstrates how the continual representation of strong female characters finding fulfillment in the roles of lover, wife, and mother is limiting, and highlights the subversive potential in ‘refactoring’ heteronormative ‘legacy code.’

利用GPS觀測量構建台灣南部地區網格式電離層模型 / A Study on Grid-Based Ionosphere Modeling of Southern Taiwan Region Using GPS Measurements吳相忠, Wu,Shiang Chung Unknown Date (has links)
電離層延遲為精密GPS定位及導航的主要誤差來源之一,為了減弱電離層延遲對GPS定位及導航的影響,可以利用雙頻GPS觀測量構建即時的區域電離層模型,以提供即時的電離層延遲誤差改正參數,修正因電離層延遲效應造成的定位及導航誤差。
本研究以台灣地區雙頻GPS觀測量,採用相位水準技術估算全電子含量(TEC)、修正的單站演算法估計各GPS衛星及接收儀之L1/L2差分延遲及以UNSW網格式演算法構建區域的電離層模型。並進而求得適合台灣南部地區網格式電離層模型之較佳網格大小及探討使用那些內政部衛星追蹤站的觀測資料,便可有效建立台灣地區的電離層模型。 / The ionospheric delay is one of the main sources of error in precise GPS positioning and navigation. The magnitude of the ionospheric delay is related to the Total Electron Content (TEC) along the radio wave path from a GPS satellite to the ground receiver. The TEC is a function of many variables, including long and short term changes in solar ionising flux, magnetic activity, season of the year, time of day, user location and viewing direction. A dual-frequency GPS receiver can eliminate (to the first order) the ionospheric delay through a linear combination of L1 and L2 observables. However, the majority of civilians use low-cost single-frequency GPS receivers that cannot use this option. Consequently, it is beneficial to estimate ionospheric delays over the region of interest, in real-time, in support of single-frequency GPS positioning and navigation applications.
In order to improve real-time regional ionosphere modelling performance, a grid-based algorithm is proposed. Data from the southern Taiwan region GPS network were used to test the ionosphere modelling algorithms. From the test results described here, it is shown that the performance of real-time regional ionosphere modelling is improved significantly when the proposed algorithm is used.

Análise in silico de regiões promotoras de genes de Xylella fastidiosa / In silico analysis on promoter sequences of protein-coding genes from Xylella fastidiosaTria, Fernando Domingues Kümmel 24 June 2013 (has links)
Xylella fastidiosa é uma bactéria gram-negativa, não flagelada, agente causal de doenças de importância econômica como a doença de Pierce nas videiras e a clorose variegada dos citros (CVC) nas laranjeiras. O objetivo do presente trabalho foi realizar análises in silico das sequências promotoras dos genes deste fitopatógeno em uma tentativa de arrecadar novas evidências para o melhor entendimento da dinâmica de regulação transcricional de seus genes, incluindo aqueles envolvidos em mecanismos de patogenicidade e virulência. Para tanto, duas estratégias foram utilizadas para predição de elementos cis-regulatórios em regiões promotoras do genoma da cepa referência 9a5c, comprovadamente associada à CVC. A primeira, conhecida como phylogenetic footprinting, foi empregada para identificação de elementos regulatórios conservados em promotores de unidades transcricionais ortólogas, levando em consideração o conjunto de genes de X. fastidiosa e 7 espécies comparativas. O critério para identificação de unidades transcricionais ortólogas, isto é, unidades trancricionais oriundas de espécies distintas e cujos promotores compartilham elementos cis-regulatórios, foi paralelamente estudado utilizando-se informações regulatórias das bactérias modelos: Pseudomonas aeruginosa, Bacillus subtilis e Escherichia coli. Os resultados obtidos com análise de phylogenetic footprinting nos permitiu acessar a rede regulatória transcricional da espécie de forma compreensiva (global). Foram estabelecidas 2990 interações regulatórias, compreendendo 80 motivos distribuídos nos promotores de 56.8% das unidades transcricionais do genoma de X. fastidiosa. Na segunda estratégia recuperamos informações regulatórias experimentalmente validadas em E. coli e complementamos o conhecimento de dez regulons de X. fastidiosa, através de uma metodologia de scanning (varredura), dos quais algumas interações regulatórias já haviam sido previamente descritas por outros trabalhos. Destacamos os regulons de Fur e CRP, reguladores transcricionais globais, que se mostraram responsáveis pela modulação de genes relacionados a mecanismos de invasão e colonização do hospedeiro vegetal entre outros. Por fim, análises comparativas em regiões regulatórias correspondentes entre cepas foram realizadas e diferenças possivelmente associadas a particularidades fenotípicas foram identificadas entre 9a5c e J1a12, um isolado de citros não virulento, e 9a5c e Temecula1, um isolado de videira causador da doença de Pierce. / Xylella fastidiosa is a gram-negative, non-flagellated bacterium responsible for causing economically important diseases such as Pierce\'s disease in grapevines and Citrus Variegated Clorosis (CVC) in sweet orange trees. In the present work we performed in silico analysis on promoter sequences of protein-coding genes from this phytopathogen, including those involved in virulence and pathogenic mechanisms, in an attempt to better understand the underlying transcriptional regulatory dynamics. Two strategies for cis-regulatory elements prediction were applied on promoter sequences from 9a5c strain genome, a proven causal agent of CVC. The first one, known as phylogenetic footprinting, involved the prediction of regulatory motifs conserved on promoter sequences of orthologous transcription units from X. fastidiosa and a set of 7 comparatives species. The criteria to identify orthologous transcription units, i. e., those from different species and whose promoter sequences share at least one common regulatory motif, was studied based on regulatory information available for model organisms: Pseudomonas aeruginosa, Bacillus subtilis and Escherichia coli. The results obtained with the phylogenetic footprinting analysis permitted us to access the underlying transcriptional regulatory network from the species in a comprehensive manner (genome-wide), with a total of 2990 regulatory interactions corresponding to 80 predicted motifs distributed on promoter sequences of 56.8% of all transcription units. In the second strategy regulatory information from E. coli was recovered and used to expand the knowledge of ten regulons in X. fastidiosa, through a scanning process, of which some regulatory interactions were previously described by independent studies. We emphasize some genes related to host invasion and colonization present in the Fur and CRP regulons, two global transcription regulators. Lastly, comparative analysis on corresponding regulatory regions among strains were performed and differences possibly associated to phenotypic variation were identified between 9a5c and J1a12, a non-virulent strain isolated from orange trees, and between 9a5c and Temecula1, a strain associated to Pierce\'s disease on grapevines.
