Lind, Norah Hardin. "Lilian Westcott Hale and Nancy Hale: From Victorian to Modern in Art and Text." VCU Scholars Compass, 2010. http://scholarscompass.vcu.edu/etd/81.
Full textAbstract:
Lilian Westcott Hale (1880-1963) and her daughter Nancy Hale (1908-1988) built successful careers during a period of transition in America, as Victorian mores were replaced by new modern freedoms. Greater independence for women had evolved during the preceding century, before the influential cultural factors which occurred during the early twentieth century like urbanization and world war. This interdisciplinary analysis of Lilian Hale‘s artwork and Nancy Hale‘s writings demonstrates the imprint of the surrounding world on their work. Lilian Hale‘s art is influenced by her Victorian childhood, and Nancy Hale‘s fiction reveals many conflicts of the modern era. The study of these two women is enhanced by the wealth of primary documentation connecting their ideas and their lives to their artistic works. Both of the women ranked among the most respected in their fields during their lifetimes. Their works resonate with elements of their eras, demonstrating what it was to be a woman during the first half of the twentieth century. Lilian Westcott Hale and Nancy Hale both engage the gender constructs of their periods through their work. Lilian Westcott Hale‘s art is divided here into three distinct genres: her still lifes and landscapes express the confining environment the Victorian woman occupied; her idealized women reflect the period‘s taste for female perfection and beauty; her portraits and figure studies point to Hale‘s own distinction between males and females through their clothing and their poses. Unlike Lilian Westcott Hale, Nancy Hale demonstrates woman‘s new freedoms in an open manner, a result of the break with Victorianism. Hale‘s use of a literary medium allows her direct examination of the turmoil caused by the modern breakdown of Victorian structures. Lilian Westcott Hale refrains from harsh judgment of her daughter‘s world, while Nancy Hale‘s modern challenge of the previous era‘s standards leads her into troubling relationships and difficulties balancing her career with her personal life. Their work reveals the cultural ideologies of their respective eras and particularly the changes taking place for women.

Full textAbstract:
This dissertation examines the intersection of gender and culture in the process of identity formation among Kanaka 'Oiwi Maoli (Indigenous Hawaiian) men in the Hale Mua 0 Maui. Throughout the neocolonial Pacific, indigenous Oceanic men have engaged in gender practices that historically have had widely different consequences for their positions of power or marginality; the cases of Hawai'i and Aotearoa/New Zealand offer important insights into the gendered dynamics of colonialism, decolonization, and reclamation. Focusing in on a deeper history of colonization and revitalization at Pu'ukohola heiau (Kawaihae, Hawai'i), I highlight the ways in which the birth of a newly gendered tradition of bravery and warriorhood in Na Koa (The Courageous Ones) led to a reconsideration of men's roles in different sectors of the Hawaiian community. One outcome was the formation of the Hale Mua, or the "Men's House," on the island of Maui. Against the legacy of American colonialism and its concomitant discourses of death, disappearance, feminization, and domestication, the Hale Mua has endeavored to build strong, culturally grounded men that will take up their kuleana (rights and responsibilities) as members of their 'ohana (families) and the larger lahui (nation). In particular, I examine the role of discursive and embodied practices of ritual, performance, and narrative in the transformation, (re)definition, and enactment of their subjectivities as Hawaiian men. The processes through which the members of the group come to define, know, and perform these kuleana articulate with the larger projects of cultural revitalization, moral regeneration, spiritual/bodily healing, national reclamation, and the uncertain and ambiguous project of mental and political decolonization. Likewise, the very writing of this dissertation has fore-grounded both the possibilities and problematics of conducting indigenous anthropology and research at home.

Full textAbstract:
O objetivo do presente trabalho é estudar a correlação entre as taxas de produção gasosa e as magnitudes heliocêntricas do cometa C/1995 O1 (Hale-Bopp), tanto na fase pré-periélica como na fase pós-periélica. As evoluções da magnitude e das taxas de produção gasosa de H2O (água), OH (radical hidroxila) e CO (monóxido de carbono), ao longo da aproximação e do afastamento do cometa em relação ao Sol, são analisadas. Para essa análise, foram utilizadas 11.734 estimativas de magnitudes visuais, extraídas do ICQ (International Comet Quarterly) e 88 observações do monóxido de carbono (Biver, comunicação particular (2007); Disanti et al. 2001; Jewitt et al. 1996), cobrindo o intervalo de distâncias heliocêntricas de rh = 7,464 UA (na fase pré-periélica) até rh = 14,070 UA (na fase pós-periélica). É mostrado que a atividade do Hale-Bopp (temperatura média superficial ~ 110 K), além de 6,3 UA do Sol é controlada pela emissão do CO (temperatura de sublimação ~ 24 K), antes que pela emissão da H2O (temperatura de sublimação ~ 152 K). Esse resultado é consistente com as observações em ondas milimétricas de Biver et al. 1996 e Jewitt et al. 1996, realizadas em 6,5 UA.The purpose of the present work is to study the correlation between the gas production rates and heliocentric magnitudes of comet C/1995 O1 (Hale-Bopp), in the pre-perihelion phase as well as in the post-perihelion phase. The evolutions of magnitudes and gas production rates of H2O (water), OH (hydroxil radical) and CO (carbon monoxide), along the approach to and leave of the comet from the Sun, are analyzed. For this analysis, we used 11,734 visual magnitude estimates, extracted from ICQ (International Comet Quarterly) and 88 observations of carbon monoxide (Biver, private communication (2007); DiSanti et al. (2001); Jewitt et al. (1996)), covering the range of heliocentric distances from rh = 7.464 AU (in the pre-perihelion phase) to rh = 14.070 AU (in the post-perihelion phase). It is shown that the activity of Hale-Bopp (average surface temperature ~ 110 K) beyond 6.3 AU from the Sun is controlled by CO emission (sublimation temperature ~ 24 K) rather than by H2O (sublimation temperature ~ 152 K). This result is consistent with millimeter-wave observations of Biver et al. (1996) and Jewitt et al. (1996), made at 6.5 AU.

Full textAbstract:
The highly flexible HALE (High Altitude Long Endurance) aircraft analysis methodology is of interest because early studies indicated that HALE aircraft might have different vibration and aeroelastic characteristics from those of conventional aircraft.
Recently the computer code Nonlinear Aeroelastic Trim And Stability of HALE Aircraft (NATASHA) was developed and used to the flight dynamics and aeroelastic analysis of flying wing HALE aircraft. Further analysis improvements were required to extend its capability to the ground vibration test (GVT) environment and to both GVT and aeroelastic behavior of HALE aircraft with other configurations.
First, the geometrically exact fully intrinsic beam theory was extended to treat other aircraft configurations modeled as an assembly of beam elements. It includes auxiliary elevator input in the horizontal tail and fuselage aerodynamics.
Second, the methodology was extended to treat the GVT environment to provide modal characteristics for model validation. A newly developed bungee formulation is coupled to the intrinsic beam formulation for the GVT modeling. After the coupling procedures, the whole formulation cannot be fully intrinsic because the geometric constraint by bungee cords makes the system statically indeterminant.
Third, because many HALE aircraft are propeller driven, the methodology was extended to include an engine/nacelle/propeller system using a two-degree-of-freedom
model. This step was undertaken to predict a dynamic instability called ``whirl flutter," which can be exhibited in such HALE aircrafts. For simplicity, two fundamental assumptions are made: constant approximation on the propeller aerodynamics and the use of equivalent three-bladed counterpart for two-bladed propeller system to obviate the need for Floquet theory. The validity of these assumptions is verified by investigating the periodic effect of side forces and hub moments and the periodic inertia effect.
Finally, parametric studies show how the current methodology can be utilized as a unified preliminary analysis tool for the vibration and aeroelastic analysis of highly flexible HALE aircraft.

ABSTRACT
Multidisciplinary Design Optimization of an Extreme Aspect Ratio HALE UAV
Bryan J. Morrisey
Development of High Altitude Long Endurance (HALE) aircraft systems is part of a vision for a low cost communications/surveillance capability. Applications of a multi payload aircraft operating for extended periods at stratospheric altitudes span military and civil genres and support battlefield operations, communications, atmospheric or agricultural monitoring, surveillance, and other disciplines that may currently require satellite-based infrastructure. Presently, several development efforts are underway in this field, including a project sponsored by DARPA that aims at producing an aircraft that can sustain flight for multiple years and act as a pseudo-satellite. Design of this type of air vehicle represents a substantial challenge because of the vast number of engineering disciplines required for analysis, and its residence at the frontier of energy technology.
The central goal of this research was the development of a multidisciplinary tool for analysis, design, and optimization of HALE UAVs, facilitating the study of a novel configuration concept. Applying design ideas stemming from a unique WWII-era project, a “pinned wing” HALE aircraft would employ self-supporting wing segments assembled into one overall flying wing. The research effort began with the creation of a multidisciplinary analysis environment comprised of analysis modules, each providing information about a specific discipline. As the modules were created, attempts were made to validate and calibrate the processes against known data, culminating in a validation study of the fully integrated MDA environment. Using the NASA / AeroVironment Helios aircraft as a basis for comparison, the included MDA environment sized a vehicle to within 5% of the actual maximum gross weight for generalized Helios payload and mission data. When wrapped in an optimization routine, the same integrated design environment shows potential for a 17.3% reduction in weight when wing thickness to chord ratio, aspect ratio, wing loading, and power to weight ratio are included as optimizer-controlled design variables.
Investigation of applying the sustained day/night mission requirement and improved technology factors to the design shows that there are potential benefits associated with a segmented or pinned wing. As expected, wing structural weight is reduced, but benefits diminish as higher numbers of wing segments are considered. For an aircraft consisting of six wing segments, a maximum of 14.2% reduction in gross weight over an advanced technology optimal baseline is predicted.

Full textAbstract:
This thesis provides a case study which investigates the notion that a building which is historically and architecturally significant to a community holds that community’s memories within its walls. It argues that, in collaboration with the members of that community, these memories can be excavated, revealed and woven together to form a piece of site-specific theatre which can then be performed by and for those community members. It proposes that this intergenerational, creative collaboration may enhance the community members’ understanding and appreciation of the significance of the building, its place in the community and their place within it.
The site of focus for this thesis is Hale School’s Memorial Hall. In order to excavate the building’s memory, members of the Hale community were invited to visit the Hall and share the recollections revealed through physical exploration of the site. Additional memories were revealed through archival research and written and verbal exchanges with community members who could not physically visit the site. These memories were then woven, in collaboration with the community, into a site-specific theatre script designed to be staged, in Memorial Hall and its surrounds, by a cast of Old Haleians, current staff members, parents and students.
This thesis consists of an original, research-based playscript, together with exegetical writing which outlines the significance of creating this work at the current time and in the chosen place. It provides new insights into methods of excavation used to reveal memory contained within a commemorative site and contributes to a broader understanding of the role of the writer in shaping the excavated memories to form a work of site-specific theatre. This thesis illustrates the importance of community consultation in both the excavation and shaping processes.

Previous issue date: 2008Este trabalho teve como objetivo estudar a atividade antimicrobiana de Canoparmelia texana (Tuck.) Elix & Hale. Extratos orgânicos foram obtidos a partir de 50g do talo liquênico, através de extrações à temperatura ambiente e a quente, obedecendo à série eluotrópica, com éter dietílico, clorofórmio e acetona. Os componentes químicos do líquen foram analisados qualitativamente e quantitativamente, através da Cromatografia em Camada Delgada (CCD) e Cromatografia Líquida de Alta Eficiência (CLAE). O ácido divaricático (DIV) foi semi-purificado a partir do extrato etéreo a quente. As propriedades antimicrobianas foram analisadas através de teste em meio de cultura sólido, biocromatografias e pela concentração mínima inibitória (CMI). Nos testes de difusão em disco, os extratos orgânicos e o ácido divaricático semi-purificado, a uma concentração de 2,5mg.mL-1, foram testados contra 14 bactérias, Gram-positivas e Gram-negativas, bem como espécies de Candida. Nos testes da CMI, os extratos e o DIV semi-purificado foram submetidos a microdiluições, a partir de uma concentração de 250 μg.mL-1. O extrato mais ativo nos testes em disco, e o ácido divaricático semi-purificado, ambos a 1mg.mL-1, foram utilizados no biocromatograma frente as bactérias Staphylococcus aureus e Escherichia coli. Dos microrganismos testados, 6 bactérias foram sensíveis, dentre as Gram-positivas, a mais sensível foi S. aureus, dentre as Gram-negativas as inibidas foram E. coli e Shigella sonnei. Não se detectou atividade frente às espécies de Candida. O ácido divaricático semi purificado apresentou o maior halo de inibição (27,5 mm), quando comparado aos extratos orgânicos. Destes, o que apresentou melhor halo foi o etéreo extraído a quente. A CIM detectada foi de 250 a 15,625 μg.mL-1, valor próximo a outras substâncias liquênicas mencionadas na literatura. O biocromatograma revelou o ácido divaricático como composto majoritário da espécie. Esse resultado pode ser ratificado pelos ensaios de CCD, que revelou a presença do DIV em todos os extratos. Em adição, uma substância não identificada, e inativa frente aos microrganismos, foi detectada nos extratos testados. Por CLAE, o DIV foi registrado em maior teor no extrato etéreo extraído a quente. Este foi o mais ativo dentre os analisados. Dessa forma, é possível indicá-lo como princípio ativo de Canoparmelia texana

Full textAbstract:
Cette thèse a permis de développer des modèles adaptés à la phase conceptuelle d'un avant-projet d'avion et particulièrement de type hale. L'analyse de la pertinence de ces modèles a été effectuée afin de recommander une utilisation adaptée à cette phase conceptuelle. Dans ce même esprit, l'approche analytique a été privilégiée. Les modèles concernent la description de l'avion et ses performances. Les modèles de performances sont abordés sous l'angle des performances "opérationnelles" et "conceptuelles". Pour l'avion, des modèles de masses, aérodynamiques et de propulsion sont proposés. Par exemple, un modèle de masse voilure a été développé sur des considérations physiques et il complète utilement les modèles statistiques classiques, Pour la propulsion, un modèle de radiateur permet de prédire l'augmentation de traînée dû au refroidissement des moteurs à piston en altitude. Les performances "opérationnelles" traitent du déroulement d'une croisière d'un avion existant. Il s'agit alors d'optimiser le pilotage de cette croisière par la recherche des paramètres opérationnels optimaux. Les modèles développés sous forme analytique, sont basés sur les formulés de Bréguet qui à cette occasion ont été améliorées en prenant en compte les différentes croisières, l'influence du nombre de Reynolds, de la montée et de l'accélération. Une forme adimensionnelle est proposée qui permet de mieux comparer les trois croisières classiques et de montrer que leurs différences sont indépendantes des paramètres conceptuels et ne dépendent que des lois de pilotage et du taux d'emport carburant. Le nombre de Reynolds a une influence sur les coefficients de portance optimaux qui évoluent par rapport aux coefficients classiques. Une optimisation numérique avec des modèles réalistes de moteur a confirmé ces résultats dans la plupart des cas. Les performances "conceptuelles" ont permis de déterminer la géométrie optimale de la voilure --- forme en plan et profil. Le coefficient de traînée de forme indépendant du nombre de Reynolds donne une surface et un allongement voilure acceptable même si la précision de la performance obtenue est faible. Le balayage des profils semble montrer que l'utilisation de profils avec des coefficients de portance maximaux plus élevés que ceux disponibles actuellement, permettrait d'améliorer les performances en endurance.

Full textAbstract:
High-altitude aircraft flying in the stratosphere (around 17-30 km altitude) can provide a useful platform for sensors to support a range of military and civilian surveillance tasks. The main topic of the thesis concerns the analysis of solar powered unmanned aerial vehicles designed for extended flight operations at high altitudes. An aft-swept flying wing configuration has been adopted for high altitude applications. Specific topics that were considered focussed on the development of a conceptual design tool and a multi-disciplinary optimisation tool able to converge on the layout for a solar powered HALE UAV. A true aft-swept flying wing is perhaps the most aerodynamically efficient aircraft configuration but, to date, has not been investigated in any detail for possible application to high-altitude UAVs. Such a configuration would require a moderate amount of wing sweep in order to generate the necessary stability in flight and to provide adequate control power for manoeuvring purposes. All systems and elements can now be placed inside the wing without compromising the weight distribution. This avoids the need for drag inducing mass balancing pods and/or reflexed trailing edge associated with unswept (straight) flying wings. Such features can either increase structural weight and/or overall drag whilst reducing the maximum lift that can be achieved. However, the design, in common with the other more conventional aircraft, represents a substantial challenge due to the simultaneous addressing of numerous inter-related engineering disciplines required for a fairly comprehensive analysis. The innovative aspect of this study was dedicated to the conceptual and preliminary design of a high altitude long endurance solar powered aft-swept flying wing and study in detail the design challenges along with the general problems associated with flying at high altitudes. Moreover, these aims were achieved by the author developing new design tools. The conceptual design tool was created to include all the aircraft elements and the expected power losses in addition to representing the drag estimation of the wing section rather than using a general expression as only a function of Reynolds number regardless the aerofoil performance. The preliminary design tool, also written by the author, represented by the composite structure model and the quasi 3D aerodynamic solver combined in a multidisciplinary optimisation framework, proved its capability in determining the aircraft geometry, its weight and its aerodynamic and structural performance capabilities.

Alíquotas retiradas, a diferentes intervalos de tempo, foram extraídas com éter/acetato de etila e clorofórmio/acetonitrila, e lidas em espectrofotômetro a 254 e 366 nm. Os extratos, após evaporados, foram avaliados por cromatografias de camada delgada (CCD) e líquida de alta eficiência (CLAE). Ensaios antimicrobianos contra Staphylococcus aureus, Bacillus subtilis, Escherichia coli e Candida albicans, através do teste de difusão em meio sólido, foram realizados utilizando os extratos brutos dos eluatos obtidos de imobilização celular, bem como do talo in natura e fenóis purificados. Os extratos mais ativos e microrganismo mais sensível foram submetidos a ensaios de biocromatografia para indicação do princípio ativo da espécie. Foi verificado que as concentrações utilizadas do precursor não influenciam na produtividade das células imobilizadas. Não houve bioprodução das substâncias, atranorina e ácido lecanórico, referidas na literatura consultada para a espécie, porém estão presentes nos extratos brutos do talo in natura. Também foi observada a presença de substâncias não identificadas nos extratos do talo natural, principalmente no clorofórmico. Não foi observada atividade antimicrobiana nos eluatos celulares, e o extrato bruto mais ativo foi o clorofórmico, seguido pelo etéreo, sobretudo contra bactérias Gram positivas. No ensaio biocromatográfico realizado com o extrato clorofórmico e B. subtilis houve formação de halo inibitório em torno da banda correspondente ao ácido lecanórico, e à substância não identificada presente no extrato. No caso dos eluatos celulares, os compostos não identificados podem ser considerados intermediários das vias metabólicas de compostos principais da espécie. Substâncias adicionais às referidas na literatura, e detectadas neste trabalho, sugerem estudos posteriores detalhados da química de P. andinum. A produção de compostos intermediários que permitam seu uso comercial, ou a síntese de outra substância, já é uma resposta positiva à técnica empregada, além de ser P. andinum uma espécie que responde satisfatoriamente aos ensaios de imobilização celular

Full textAbstract:
This study aims at uncovering the formation mechanism of the recent bright gully deposits observed on Mars in order to assess the viability of liquid water involvement. I use a high resolution topography model as input into a kinematic model to assess whether or not a dry granular flow could form the bright gully deposits seen in Hale Crater. I investigate a dry mechanism due to the difficulty of producing water on the martian surface under present-day pressure and temperature conditions. I examine a range of particle sizes, flow thicknesses, and upslope initiation points to examine how these parameters affect the run-out distances of flows. The results show that multiple combinations of parameters could produce flows that travel to within the observed deposits' boundaries. The results suggest that the recent bright gully deposits are not evidence of recent liquid water on the surface of Mars.

Full textAbstract:
Ces dernieres annees, 3 cometes ont permis d'ameliorer notre connaissance du milieu cometaire : la comete de halley etudiee in-situ en 1986, la comete hyakutake qui s'est beaucoup approchee de la terre en 1996 et la tres active comete hale-bopp en 1997. Des spectres a haute resolution spatiale de la comete de halley ont ete obtenus pendant la mission vega 2 en mars 1986. Dans le proche-uv, plusieurs bandes d'emission apparaissent a des distances cometocentriques inferieures a 3000 km. L'une d'elles, a 323 nm, ne peut etre expliquee par aucune molecule habituellement observee dans les cometes. Elle a aussi ete detectee dans un spectre la veille de la rencontre sonde-comete a 350000 km du noyau, suggerant que les molecules responsables de cette bande ont ete liberees localement, probablement par des grains. Des spectres en phase liquide suggeraient qu'une molecule polycyclique aromatique (pah), le naphtalene, pouvait etre un candidat. Nous avons obtenu des spectres de fluorescence du naphtalene au laboratoire dans des conditions qui simulent la situation cometaire. Le resultat, une bande large centree sur 350 nm, ne permet pas d'expliquer l'emission observee a 323 nm qui demeure non-identifiee. Nous devons noter que les pah forment une famille dans le milieu interstellaire et que les cometes sont formees a partir de matiere interstellaire. Parmi les pah, certains, tels que le methylnaphtalene ou le fluorene, emettent autour de 323 nm en phase liquide et peuvent etre des candidats mais des spectres de fluorescence en phase gazeuse doivent etre obtenus dans des conditions de laboratoire qui simulent l'environnement cometaire. Des spectres iue de la comete hyakutake ont ete obtenus en fevrier et mars 1986. Sa faible distance geocentrique a permis d'observer avec une grande resolution spatiale et d'etudier la coma interne ou sont concentrees les molecules a courte duree de vie liberees par le noyau. C'est le cas de s 2 qui a une duree de vie de 250 s et emet dans la region spectrale enregistree par iue. Nous avons elabore un modele de fluorescence de s 2 dependant du temps qui montre que les molecules atteignent un etat proche de celui de l'equilibre en 200 s. La comparaison entre le spectre calcule et le spectre iue de la comete iras-araki-alcock qui a permis la decouverte de s 2 montre que les molecules sont proches de l'equilibre. Dans les cometes iras-a-a et hyakutake relativement peu actives, les collisions ne ralentissent pas la fluorescence et les molecules ont le temps d'atteindre l'equilibre avant d'etre photodissociees. La comparaison du spectre a l'equilibre avec un spectre iue de la comete hyakutake enregistre pendant une heure, deux jours apres le perigee, suggere que les spectres calcule et observe peuvent etre correles et donne une limite superieure de l'abondance de 0,01% par rapport a l'eau. Cette detection a ete confirmee cinq jours plus tard par des observations avec hst. Les cometes brillantes hyakutake et hale-bopp ont ete observees dans le domaine visible a l'observatoire de haute provence. Des traitements d'image revelent plusieurs structures dans la coma. Dans la comete hyakutake, ce sont des jets de poussiere du cote du soleil, deux condensations le long de la queue et un croissant observe dans l'emission de c 2 entre le noyau et la premiere condensation. Les condensations sont restees alignees dans la queue pendant plusieurs semaines. Ce sont des amas de particules liberes par le noyau et non des fragments solides. Dans la comete hale-bopp, les structures sont des arcs de poussiere regulierement espaces dans l'hemisphere ensoleille et des arcs de c 2 qui s'etendent dans l'autre hemisphere. Notre programme de spectroimagerie a utilise quatre filtres a bande passante etroite. Deux isolent les tetes de bandes (1,1) et (0,0) de c 2 a 513 et 516 nm et deux autres mesurent le continuum a 527 et 682 nm. Le rapport d'intensite i(513 nm)/i(516 nm) donne le degre d'excitation des molecules c 2. I(682 nm)/i(527 nm) donne la couleur de la poussiere et caracterise sa distribution en taille. L'etude de ces 2 parametres a revele la presence de sources etendues ou c 2 a un degre d'excitation eleve. Il est produit par la photolyse de molecules liberees non pas par le noyau mais localement par des grains de poussiere. Dans la comete hyakutake, la source diffuse est le croissant, probablement lie a la liberation des condensations. Dans la comete hale-bopp, elle correspond aux arcs concentriques dans l'hemisphere ensoleille. Les observations des cometes halley (in-situ), hyakutake et hale-bopp ont ameliore notre comprehension du milieu cometaire mais de nombreux problemes resteront sans reponse avant que des sondes spatiales n'aillent explorer des noyaux cometaires.

Full textAbstract:
Esta dissertação descreve e analisa os verbos da língua Juruna (Yudja) a partir de suas estruturas argumentais e conseqüências sintáticas. O objetivo é contribuir com um material para a escola indígena Juruna assim como contribuir com os estudos teóricos da perspectiva gerativista de estudos sobre a linguagem. O texto é dividido em duas grandes partes (descrição e análise) sendo a primeira delas uma descrição de 302 verbos da língua. Nesta parte dividimos estes verbos em dezoito classes verbais a partir de critérios morfológicos, sintáticos e semânticos. Estes critérios foram estabelecidos a partir de características da língua, quais sejam estas: duplicação verbal, propriedades semânticas, afixos, causativização e propriedades das raízes - as quais associadas a verbalizadores formam os verbos. Nesta seção apresentamos quais são as construções e operações morfológicas que cada verbo descrito realiza (tais como: alternâncias de valência (por afixação e via alternância labile), duplicação e supleção verbal) e suas funções na língua. A segunda parte do texto denominada \"análises\" apresenta uma análise gerativa para os fatos da língua Juruna. Para a questão da formação dos verbos, partimos da proposta de Hale & Keyser (1993; 2001) segundo a qual os verbos são formados de forma estrutural e hierárquica a partir de duas estruturas básicas (monádica e diádica) nucleadas por núcleos verbais (V1 e V2). Estas estruturas são utilizadas de forma paramétrica a partir de restrições das raízes verbais e seus traços sintáticos e semânticos. Considerando esta proposta teórica, argumentamos que os verbos da língua Juruna são formados estruturalmente a partir de restrições dos traços que formam as raízes verbais, os quais também serão determinantes nos processos de atribuição e mudança de valência e voz assim como no processo de duplicação e supleção verbal. Após a análise referente à formação dos verbos apresentamos a formação de sentenças na língua Juruna partindo do Programa Minimalista (Chomsky 1995; 1998; 1999). Nesta seção apresentamos o processo de inserção de sujeitos (a partir de formas pronominais, demonstrativos e sintagmas nominais) em vP, discutimos os processos de concordância, analisamos a inserção de modo realis/ irrealis, bem como questões relacionadas a ordem sentencial, adjunção de advérbios e o paralelismo entre os planos nominal e verbal, a partir das questões associadas à cumulatividade e quantificação. O ponto central desta dissertação é, portanto, argumentar que todas as propriedades sintáticas da língua Juruna decorrem essencialmente dos traços formadores de seus verbos. Desta forma, para a compreensão da sintaxe de uma língua é necessário compreender a estrutura argumental de seus verbos.This dissertation describes and analyzes Juruna (Yudja) verbs based on argument structure and its syntactic consequences. We aim to offer to the Juruna School useful material about verb classes and also to contribute to the advancement of language studies in the generativist framework. The dissertation is divided in two parts - description and analysis). The first is a description of 302 verbs in this language. In this part, we divided verbs in eighteen classes based on morphological, syntactic and semantic criteria established from phenomena present in Juruna. These phenomena are: verb reduplication, semantic properties of roots and affixes, causativization and properties of roots that, associated to verbalizers, form verbs. We presented constructions and morphological operations that each verb described realize, for instance: valence alternation (by affixation or labile alternation), reduplication and suppletion and their functions in this language. The second part of the dissertation - entitled \"analysis\" - presents a generativist account of some Juruna facts described in the first part. To discuss verb formation we based ourselves on Hale & Keyser\'s (1993; 2001) proposal that verbs are formed from two basic structures (monadic and dyadic) with verbal nuclei (V1 and V2) organized structurally and hierarchically. These structures are utilized parametrically, taking into consideration verbal root restrictions and syntactic and semantic traces. Supported by this theorical proposal, we argued that verbs in Juruna are formed structurally based on restrictions of their root. These restrictions will also determine the process of attribution and change of valence and voice and the processes of verb duplication and suppletion in the language. After the analysis of verb formation, we present a hypothesis of sentence structure in Juruna based on the Minimalist Program (Chomsky 1995; 1998; 1999). In this section we discussed: 1) subject insertion (taking into consideration pronominal forms, demonstratives and nominal phrases) in vP; 2) agreement processes; 3) the insertion of mood realis/ irrealis; 4) sentential order; 5) adverbial adjunction and 6) the parallelism between nominal and verbal domains based on cumulativity and quantification. The central theoretical point of this dissertation is to argue in favor of the idea that syntactic properties may be explained, in large part, as a consequence of verb formation. In this sense, to understand the syntactic structure of a language it is essential to understand the argument structure of its verbs.

Full textAbstract:
Offshore wind power production is an attractive clean energy option, but the difficulty of access can lead to expensive and rare opportunities for maintenance. Smart loads management (controls) are investigated for their potential to increase the fatigue life of damaged offshore wind turbine rotor blades. This study will consider two commonly encountered damage types for wind turbine blades, the trailing edge disbond (bond line failure) and shear web disbond, and show how 3D finite element modeling can be used to quantify the effect of operations and control strategies designed to extend the fatigue life of damaged blades.
Modern wind turbine blades are advanced composite structures, and blade optimization problems can be complex with many structural design variables and a wide variety of aeroelastic design requirements. The multi-level design method is an aeroelastic structural design technique for beam-like structures in which the general design problem is divided into a 1D beam optimization and a 2D section optimization. As a demonstration of aeroelastic design, the multi-level design method is demonstrated for the internal structural design of a modern composite rotor blade. Aeroelastic design involves optimization of system geometry features as well as internal features, and this is demonstrated in the design of a flying wing aircraft. Control methods such as feedback control also have the capability alleviate aeroelastic design requirements and this is also demonstrated in the flying wing aircraft example.
In the case of damaged wind turbine blades, load mitigation control strategies have the potential to mitigate the effects of damage, and allow partial operation to avoid shutdown. The load mitigation strategies will be demonstrated for a representative state-of-the-art wind turbine (126m rotor diameter). An economic incentive will be provided for the proposed operations strategies, in terms of weighing the cost and risk of implementation against the benefits of increased revenue due to operation of damaged turbines. The industry trend in wind turbine design is moving towards very large blades, causing the basic design criterion to change as aeroelastic effects become more important. An ongoing 100 m blade (205 m rotor diameter) design effort intends to investigate these design challenges. As a part of that effort, this thesis will investigate damage tolerant design strategies to ensure next-generation blades are more reliable.

Full textAbstract:
L'idée d'un drone solaire haute altitude disposant d'une endurance virtuellement infinie, uniquement limitée par des questions de maintenance, fait sont chemin au sein de la communauté aéronautique. Toutefois, en raison de la faible puissance fournie par l'énergie solaire, ce concept nécessite l'utilisation d'une voilure à grand allongement très légère et donc très souple, ce qui la rend vulnérable à des phénomènes d'instabilités destructeurs comme le flottement ou la divergence en torsion. Ces travaux consistent à développer un code de calcul adapté à la physique complexe d'un tel aéronef, permettant d'exploiter les spécificités des matériaux composites pour éviter la présence de ces instabilités dans le domaine de vol. En complément de cas tests issus de la littérature, une campagne d'essais en soufflerie a été menée pour valider la performance du programme. Pour finir, sa capacité à être utilisé au sein d'une plateforme d'optimisation a été illustrée à travers un cas simple de plaque souple compositeThe idea of high altitude solar drones, with a virtually infinite endurance, only restrained by maintenance issues, gain ground in the aviation community. However, because of the low on-board power, this concept implies to design a very lightweight high aspect-ratio wing which is very flexible and then vulnerable to destructive instabilities like flutter or torsional divergence. This work consists in developing a computation code, namely GEBTAero, suitable for this type of airframe, allowing to exploit composite materials specificity to avoid such instabilities in the flight domain. Besides literature test cases, a wind tunnel campaign is conducted in order to validate the program performances. Lastly, its ability to be used within an optimisation framework is assessed with a simple shape composite flat plate

Full textAbstract:
William Hale White "Mark Rutherford", (1831-1913) est avant tout connu comme auteur d'une autobiographie romancée écrite sous la pression d'une intense inquiétude spirituelle et métaphysique. Né à Bedford dans un milieu de dissidents non-conformistes, ses écrits ne se font pas seulement l'écho de l'expérience poignante de la perte de la foi et de l'irruption du doute religieux sous l'effet de la critique biblique et du développement de connaissances dans le domaine des sciences, mais ils mettent aussi en évidence avec beaucoup de subtilité le très grand fractionnement du paysage religieux anglais dans une petite ville de province. White ne se considéra jamais comme un professionnel de l'écriture. Il avait cinquante ans lorsqu'il publia The Autobiography (1881) puis The Deliverance (1884), deux courts récits qui constituent lřhistoire fictionnalisée de son expérience personnelle dans lesquels il décrit les difficultés rencontrées par le narrateur-personnage principal dans son désir de trouver une forme de « délivrance » qui lui permette de refonder ses certitudes ébranlées en redonnant à son existence une orientation rassurante et clairement définie. Ce travail accorde une large place à l'histoire des idées religieuses et intellectuelles, aux relations entre religion et culture ; il s'efforce de reconstituer certains aspects du paysage religieux et idéologique de l'époque victorienne à partir de la prise en compte de l'itinéraire de White, qui est entièrement placé sous le signe de la rupture avec les formes les plus traditionnelles de croyance. Il s'intéresse aussi à la dimension sociale, culturelle et éthique des débats spirituels et religieux en Grande-BretagneWilliam Hale White "Mark Rutherford" (1831-1913) is best known as the author of a fictionalized autobiography written under the pressure of intense spiritual and metaphysical concerns during the Victorian period. Born in a non conformist background in Bedford, his writings not only mirror his loss of faith and the Victorian crisis of doubt triggered by Biblical criticism and the new developments in sciences at the time, but they also highlight with great subtlety the varied religious and political landscape in an English country town. White did not consider himself as a professional author. He was fifty when his first works were published. In his fictional autobiographical writings, The Autobiography of Mark Rutherford (1881) and Mark Rutherford's Deliverance (1884), William Hale White describes the agonies of religious doubt in the mid-19th century. This dissertation is not only a study of White's work and background, but also a study of the history of intellectual and religious ideas, as well as an analysis of the social, cultural, ethical and religious debates in Great Britain. The intellectual and historical approach of this work discusses the debates between culture, religion and ethics in the Victorian period

Full textAbstract:
La comète C/1995 O1 (Hale-Bopp) a sans doute été l'une des comètes les plus brillantes jamais observées jusqu'à présent. Son extraordinaire activité a permis pour la première fois d'entreprendre des observations en interférométrie millimétrique avec une grande sensibilité. Lors de son passage au périhélie, les transitions J(2-1) et J(1-0) du monoxyde de carbone, ont été observées avec l'interféromètre du Plateau de Bure de l'Institut de Radio Astronomie Millimétrique (IRAM), à 230 GHz et 115 GHz respectivement. L'analyse temporelle des observations faites en parallèle en mode antenne unique a d'abord permis de mettre en évidence la présence d'un jet de CO en rotation dans l'atmosphère de la comète. L'étude des cartes interférométriques a ensuite montré que la coma était spatialement et spectralement anisotrope. Afin d'analyser au mieux ces données, nous avons développé un modèle d'atmosphère cométaire en 3 dimensions, et simulé les observations. Le modèle consiste en une coma isotrope à laquelle on ajoute un jet de forme conique qui spirale dans la coma à cause de la rotation du noyau. La comparaison des simulations aux observations s'est faite sur l'évolution temporelle des décalages spectraux, et sur celle des visibilités, qui sont les quantités physiques qu'un interféromètre mesure et qui représentent la Transformée de Fourier de la distribution de brillance du gaz sur le plan du ciel. Cette étude a confirmé la présence d'un jet spiralant dans la coma. De plus, nous avons pu déterminer les paramètres du jet tels que la position, l'ouverture et l'intensité, qui interprètent au mieux les observations. La question de l'origine de CO dans la coma est également abordée en dernière partie. Nos observations suggèrent que cette molécule proviendrait pour moitié du noyau, et pour moitié d'une source étendue.

A esquistossomose é uma doença endêmica distribuída em regiões tropicais e subtropicais, que pode ser controlada através do molusco Biomphalaria glabrata. O objetivo desde trabalho foi avaliar as atividades embriotóxicas, moluscicida e artemicida do extrato etéreo, da atranorina e do ácido praesorediósico, ambos purificados de Parmotrema praesorediosum. A partir do extrato obtido de P. praesorediosum com éter dietílico foram realizados isolamento e purificação do ácido praesorediósico e da atranorina. O extrato etéreo e as substâncias purificadas foram analisadas através de CCD, CLAE, RMN-H1 e RMN-C13. Para a realização dos bioensaios, todas as substâncias analisadas foram dissolvidas em DMSO (0,25%) e expostas por 24 h a 25˚C e foram utilizados grupos controle negativos (água e DMSO a 0,25%) e positivos (niclosamida 20 μg/mL e carbonato cúprico 50 μg/mL). Para os ensaios de embriotoxicidade com B. glabrata utilizou-se as seguintes concentrações para o extrato etéreo 1000, 500, 300, 250, 150, 100, 50 e 25 μg/mL, a atranorina 1000, 500 e 250 μg/mL e o ácido praesorediósico 500, 250 e 125 μg/mL. Após a exposição, os embriões foram observados por 8 dias consecutivos e classificados como inviáveis (embriões mortos e malformados) e viáveis (embriões eclodidos). Os experimentos foram realizados em triplicata com 100 embriões por grupo. Para os testes moluscicidas foram selecionados 150 animais, que foram colocados em recipientes individuais com água filtrada para verificar a maturidade sexual e, em seguida foram separados 120 animais sexualmente maduros. Os moluscos (n=5) foram separados e submetidos ao extrato etéreo 200, 150, 100, 50 e 25 μg/mL e a atranorina purificada 500, 250 e 125 μg/mL, e os testes foram realizados em triplicata para cada concentração e avaliados durante 8 dias. Para o ensaio de toxidade ambiental com A. salina utilizou-se o extrato etéreo 1000, 500, 250, 100, 50 e 25 μg/mL, a atranorina purificada 1000, 500, 250, 125 e 62,5 μg/mL e o ácido praesorediósico purificado 200, 125, 62,5 μg/mL incubados em água do mar. Os testes foram realizados em quadruplicata com 5mL da solução com dez larvas por tubo de ensaio. Os grupos foram analisados quanto à frequência de letalidade e sobrevivência. Os testes estatísticos utilizados foram o ANOVA e o pós-teste Newman- keuls com p < 0,05. A embriotoxicidade do extrato etéreo e do ácido praesorediósico purificado foram comprovados, pois as substâncias apresentaram valores de CL50 de 363,07 μg/mL e 213,79 μg/mL, respectivamente. A CL50 estimada para os moluscos tratados com o extrato etéreo foi de 102,32 μg/mL demonstrando ser bastante eficiente no combate ao hospedeiro intermediário. A atranorina purificada não apresentou toxicidade sobre embriões e moluscos. Os ensaios demonstraram que o extrato etéreo, a atranorina e o ácido praesorediósico, ambos purificados, apresentaram baixa toxicidade ao microcrustáceo, indicando que estas substâncias oferecem baixo risco ao meio ambiente. A toxicidade do extrato etéreo e do ácido praesorediósico purificado do líquen P. praesorediosum nas diferentes concentrações testadas causou significativa letalidade sobre embriões e moluscos de B. glabrata, demonstrando ser bastante promissor visto que pode ser considerado como potente agente moluscicida.
Schistosomiasis is endemic distributed in tropical and subtropical regions, which can be controlled by the snails Biomphalaria glabrata. The purpose since work was to evaluate the embryotoxic activities, molluscicide and artemicida ether extract, the atranorin and praesorediosic acid, both of purified Parmotrema praesorediosum. From the extract obtained from P. praesorediosum with diethyl ether was carried out isolation and purification of praesorediosic acid and atranorin. The ether extract and the purified compounds were analyzed by CCD, HPLC, RMN-H1 and RMN-C13. To achieve the bioassays, all analyzed substances were dissolved in DMSO (0.25%) and exposed for 24 hours at 25˚C and used negative control (water and DMSO 0,25%) and positive (niclosamide 20 μg/mL cupric carbonate and 50 μg/mL). For embryotoxicity tests with B. glabrata was used for the following concentrations ether extract 1000, 500, 300, 250, 150, 100, 50 and 25 μg/mL, the atranorin 1000, 500 and 250 μg/mL and acid praesorediosic 500, 250 and 125 μg/mL. After exposure, the embryos were observed for 8 consecutive days and are classified as non-viable (dead embryos and malformed) and viable (hatched embryos). The experiments were performed in triplicate with 100 embryos per group. To test molluscicides 150 animals were selected, which were placed in individual containers with filtered water to check sexual maturity, and then were separated 120 sexually mature animals. The snails (n= 5) were separated and subjected to ether extract 200, 150, 100, 50 and 25 μg/mL and atranorin purified 500, 250 and 125 μg/mL, and tests were performed in triplicate for each concentration and evaluated for 8 days. For environmental toxicity test with A. salina used the ether extract 1000, 500, 250, 100, 50 and 25 μg/mL, the purified atranorin 1000, 500, 250, 125 and 62.5 μg/mL and purified acid praesorediosic 200, 125, 62.5 μg/mL incubated in sea water. The tests were performed in quadruplicate with 5mL of the solution with ten larvae per test tube. The groups were analyzed for frequency and lethality survival. Statistical analyzes were performed using ANOVA and the Newman-Keuls post-test with p<0.05. Embryotoxicity ether extract and the purified acid praesorediosic been proven, as the substances showed CL50 values of 363.07 μg/mL to 213.79 μg/mL, respectively. The CL50 estimated for snails treated with ether extract was 102.32 μg/mL demonstrating to be quite efficient in combating intermediate host. The atranorin purified showed no toxicity to embryos and snails. The tests showed that the ether extract, the atranorin and praesorediosic acid, both purified, showed low toxicity microcrustacean, indicating that these substances offer low risk to the environment. The toxicity of ether extract and the purified acid praesorediosic lichen P. praesorediosum in different concentrations tested caused significant mortality of embryos and snails B. glabrata, proving to be very promising as it can be considered as potent molluscicidal agent.

The overall objective of this research was to realise the practical application of Hierarchical Asynchronous Parallel Evolutionary Algorithms for Multi-objective and Multidisciplinary Design Optimisation (MDO) of UAV Systems using high fidelity analysis tools. The research looked at the assumed aerodynamics and structures of two production UAV wings and attempted to optimise these wings in isolation to the rest of the vehicle. The project was sponsored by the Asian Office of the Air Force Office of Scientific Research under contract number AOARD-044078. The two vehicles wings which were optimised were based upon assumptions made on the Northrop Grumman Global Hawk (GH), a High Altitude Long Endurance (HALE) vehicle, and the General Atomics Altair (Altair), Medium Altitude Long Endurance (MALE) vehicle. The optimisations for both vehicles were performed at cruise altitude with MTOW minus 5% fuel and a 2.5g load case. The GH was assumed to use NASA LRN 1015 aerofoil at the root, crank and tip locations with five spars and ten ribs. The Altair was assumed to use the NACA4415 aerofoil at all three locations with two internal spars and ten ribs. Both models used a parabolic variation of spar, rib and wing skin thickness as a function of span, and in the case of the wing skin thickness, also chord. The work was carried out by integrating the current University of Sydney designed Evolutionary Optimiser (HAPMOEA) with Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) tools. The variable values computed by HAPMOEA were subjected to structural and aerodynamic analysis. The aerodynamic analysis computed the pressure loads using a Boeing developed Morino class panel method code named PANAIR. These aerodynamic results were coupled to a FEA code, MSC.Nastran® and the strain and displacement of the wings computed. The fitness of each wing was computed from the outputs of each program. In total, 48 design variables were defined to describe both the structural and aerodynamic properties of the wings subject to several constraints. These variables allowed for the alteration of the three aerofoil sections describing the root, crank and tip sections. They also described the internal structure of the wings allowing for variable flexibility within the wing box structure. These design variables were manipulated by the optimiser such that two fitness functions were minimised. The fitness functions were the overall mass of the simulated wing box structure and the inverse of the lift to drag ratio. Furthermore, six penalty functions were added to further penalise genetically inferior wings and force the optimiser to not pass on their genetic material. The results indicate that given the initial assumptions made on all the aerodynamic and structural properties of the HALE and MALE wings, a reduction in mass and drag is possible through the use of the HAPMOEA code. The code was terminated after 300 evaluations of each hierarchical level due to plateau effects. These evolutionary optimisation results could be further refined through a gradient based optimiser if required. Even though a reduced number of evaluations were performed, weight and drag reductions of between 10 and 20 percent were easy to achieve and indicate that the wings of both vehicles can be optimised.

This thesis uses behavioral mapping to analyze two contrasting spaces in Kansas State University’s Hale Library. One of the spaces is meant for computer use; and the other for general library use, including study-group work. The conceptual approach chosen to describe and analyze these two library spaces is the behavior-setting theory developed by psychologist Roger Barker, who defines behavior settings as independent units of space, with temporal and spatial boundaries, that have “great coercive power over the behaviors that occur within them” (Barker, 1968, p. 17). The behavioral observations for the two Hale Library spaces were analyzed and compared with findings from other studies of library usage and behaviors. In the first chapter of the thesis, I introduce my study topic and discuss recent developments in libraries. In the second chapter, I provide a broad overview of library history and library use. I also overview behavior-setting theory and present examples of research on behavior settings and libraries. In the third chapter, I discuss research methods for this thesis, starting with how library spaces can be described as behavior settings. I then discuss specific methodological procedures involved in the behavioral study of activities in the two library spaces. In the fourth chapter, I discuss the two spaces studied in Hale Library, first, describing their physical features and then discussing their behavior-setting attributes. In the fifth chapter, I present my behavioral observations and compare and contrast the two Hale Library spaces in terms of user behaviors and as behavior settings. In the sixth and final chapter of this thesis, I compare my research results with other library research and offer my speculative ideas on the future of the academic library. The overarching theme of this thesis is evaluating how recent digital technologies have affected libraries, and how traditional library spaces and spaces designated for digital technology can be integrated in future libraries.

Full textAbstract:
Along the coastlines of the Hawaiian Islands, there is a valuable and critical resource known for its brackish water habitat – loko i‘a (Hawaiian fishponds). They are dynamic systems dependent on the balance between fresh groundwater inputs from uka (uplands) and landward flow of kai (seawater), which all vary depending on the behavior of our climate, including rainfall, tides, and storms. Nutrient-rich groundwater mixing with the seawater at the coast allows for an abundant growth of limu or primary productivity attracting many of Hawaii’s favorable native brackish water and herbivorous species. Having an intimate relationship with this natural coastal nursery, Hawaiians effectively modified these coastal habitats into loko i’a to provide a sustainable food source for the communities in which they reside. In support of these invaluable resources and practices, this study seeks to understand primary productivity and salinity relationships along the same coastline at Honokea Loko of Waiuli, and Hale o Lono and Waiāhole/Kapalaho of Honohononui, Hawaii. Weekly water quality monitoring by kiai' loko (fishpond steward) and biweekly water column sampling, salinity in the three loko i’a ranged from 3.1 to 18.8 and was significantly different throughout different areas of each pond. Benthic primary productivity experiments, found significantly more growth at higher salinity locations across all sites. Due to these strong correlations, loko i'a communities would greatly benefit from these methodologies to quantify the variability of environmental changes through time and specific impacts of climate phenomena, changes in rainfall and sea level. These factors have the potential to interfere with primary productivity and alter loko i'a systems interactions entirely.

Studio di fattibilità della conversione del Vought V-173 per il volo ad alta quota.
Per realizzare l'intero lavoro si è adoperato il software di fluidodinamica computazionale Flow Simulation di SolidWorks e si è scelto l'ambiente Matlab per la fase di elaborazione e presentazione dati.
A partire dal modello tridimensionale in SolidWorks del V-173 si sono ricreate le curve CL e CD a partire dai punti ottenuti dalle simulazioni per diverse configurazioni del velivolo. Si è valutata l'aerodinamica del velivolo senza la presenza di eliche e di ipersostentatori e successivamente si sono seguite due strade diverse per valutare il comportamento del velivolo: nel primo caso si sono eseguiti studi dell'aerodinamica del Pancake in presenza degli ipersostentatori già presenti sul velivolo originario (i plain flap). In secondo luogo, tenendo in considerazione che il Pancake è un aeroplano bielica, si è voluta studiare l'influenza delle due eliche sulla sua aerodinamica: dopo aver riprodotto nel modo più verosimile entrambe le eliche utilizzando SolidWorks si è fatto uno studio di massima ricavando risultati che potessero indicare la compatibilità tra elica e velivolo a seguito dei risultati sperimentali ottenuti con Flow Simulation. Questa parte è stata realizzata per lo stesso tipo di elica tripala, ma prendendo in considerazione due diversi diametri, una di 4:9m e una da 2:5m.

Full textAbstract:
Emmanuel Levinas's philosophy of ipseity and alterity has permeated Western thought for more than forty years. In the social sciences and the humanities, the recognition of the Other and focus on difference, alterity, has influenced the way we ethically approach peoples and arts from different cultures. Because focus on the ego, ipseity, limits our ethical obligations, focusing on the Other does, according to Levinas, bring us closer to an ethical life. Furthermore, the self maintains responsibility for the Other and must work within Levinas's ethical system to become truly responsible. Therefore, the interaction between self and Other is Levinas's principal concern as we move toward the New Humanism. The traditional Western autobiography has been centered in the self, the ego, which may prevent the ethical interaction on the part of the writer because the writer often portrays himself or herself as exemplary or unique rather than as an individual within a culture who is responsible for others. Nevertheless, life writing has expanded as writers strive to represent themselves and their cultures responsibly. One form that has emerged is the literary autoethnography, a memoir that considers ancestry, culture, history, and spiritual inheritance amidst personal reflection. In particular, Native American conceptions of the self within story have inspired conventions of literary autoethnography. This project explores the way Native American worldviews have influenced the autoethnography by looking at four Native American authors: Janet Campbell Hale, N. Scott Momaday, Leslie Marmon Silko, and Carter Revard. Through research, family stories, interviews, and returns to ancestral spaces, autoethnographers can bring themselves and their readers closer to cultural consciousness. By investigating standards in autoethnographic works, this project will illustrate the ethical intentionality of autoethnography.
