Abstract:
The aim of this thesis was to examine, describe and assess in detail the method, process, and outcome of the first national Turkish technology foresight study - Vizyon 2023 - and draw conclusions about its effect on the Turkish science, technology and innovation system. Technology foresight has gained widespread acceptance all over the world as a policy tool used in identifying future technologies, setting priorities, formulating science and technology policies and wiring up the national system of innovation. In this context, a review of the literature on technology foresight is undertaken and major concepts are established. The cases of the French and Hungarian technology foresights are examined in comparison to the Turkish technology foresight. Particular emphasis is given to describe the link to science and technology policy of the Vizyon 2023 technology foresight in order to assess its immediate and expected impacts. It is concluded that the Vizyon 2023 technology foresight was a carefully practiced study in line with current trends and knowledge, the linkage to policy was successful, but the result fell short in pointing to clear directions in terms of the implementation agenda. Furthermore, it is ascertained that the science and technology strategy formulated on the basis of the Vizyon 2023 Technology Foresight can only be successful, if implemented with the close coordination and collaboration of all actors of the national innovation system.

Abstract:
En el presente documento se ha propuesto el Plan Estratégico de Trupal para ser desarrollado en los próximos cinco años, en el cual se pretende posicionar a la empresa como referente en sus distintas áreas de negocios: flexibles, papeles y cajas. Para ello, se ha comenzado por explicar el modelo secuencial creado por D´Alessio (2013). El modelo comienza por definir estratégicamente cuál será la visión, misión, valores y código de ética de Trupal para el periodo ya mencionado. Posteriormente, se hizo una exhaustiva revisión externa sobre los factores que influencian las actividades de la misma, utilizando la modalidad del análisis PESTE considerando al país y sus factores más relevantes, la industria y los competidores. Seguidamente, se hizo el análisis interno tomando en consideración los elementos del análisis AMOFHIT. Del análisis interno y externo junto con los intereses organizacionales se propusieron siete objetivos de largo plazo (OLP) que ayudarán a la empresa a consolidarse como referente en su industria. Una vez fueron definidos los OLP, se identificaron seis amenazas, siete debilidades, siete fortalezas y 10 oportunidades de la empresa que sirvieron para definir cuáles serán las estrategias que llevarán adelante el cumplimiento de la visión propuesta. 10 estrategias fueron elegidas después de haber pasado por varios filtros de viabilidad y junto a ellas 22 objetivos de corto plazo (OCP) que servirán como acciones concretas y específicas a ser ejecutadas. El planeamiento estratégico desarrollado es una muestra de un plan ambicioso que propone el crecimiento orgánico de Trupal, velando por el interés de las partes interesadas hacía la consecución de un futuro próspero y sostenido por parte de la Organización.
The present document proposes the Strategic Planning of Trupal to be developed in the next five years. The intention is to put the company as a reference in its different business areas: flexible, paper and cardboard. For that matter, the strategic plan starts by defining which are going to be the vision, mission, values and code of ethics for the already mentioned period. Thereupon, an exhaustive review was conducted considering the factors that influence the activities of the company, using the PESTE analysis, which considers the most critical factors of a country, the industry and competitors. Subsequently, the internal analysis was conducted using the AMOFHIT analysis. From the external and internal analysis together with the organizational interests, seven long-term objectives (LTO) were proposed to assist the company to consolidate as a reference in its industry. With the LTO defined, it was possible to identify six threats, seven weaknesses, seven strengths and 10 opportunities that helped determine the necessary strategies to carry forward the fulfillment of the proposed vision. 10 strategies were chosen after thorough filters to prove their viability, and with them 22 short-term objectives (STO) that will serve as concrete and specific actions to be enforced. The strategic planning developed is an example of an ambitious plan that aims for the organic growth of Trupal, ensuring the interest of the stakeholders towards the achievement of a successful and sustained future of the organization.

Introdução: O mesotelioma é um tumor raro que afeta principalmente a pleura e a cavidade peritoneal e um dos desfechos da exposição ao asbesto, classificado como cancerígeno tipo I pela International Agency for Research on Cancer. A exposição ao asbesto pode ser ocupacional ou ambiental. A contribuição da exposição ocupacional ao asbesto para o mesotelioma é estimada em 70 a 80%. As manifestações clínicas começam 35 a 45 anos depois da exposição, evidenciando um longo período de latência. Embora a exposição ao asbesto ocorra entre os trabalhadores que produzem, manipulam ou comercializam este produto, a população geral também pode se expor e desenvolver, como conseqüência, essa neoplasia. A mortalidade por mesotelioma é um dos indicadores mais sensíveis e relevantes para o monitoramento dos efeitos do asbesto sobre a saúde. Esta neoplasia maligna pode ser evitada e a principal recomendação da Organização Mundial da Saúde é o banimento, já implementado em mais de 50 países. A Argentina é um desses países, medida formalizada com a Resolução n º 845/2001 do Ministério da Saúde. Embora essa normativa esteja vigente, é de se prever que continuem e continuarão a ocorrer casos de mesotelioma. Há poucos estudos sobre o mesotelioma na Argentina, não existem estimativas nacionais atuais da mortalidade, bem como informações sobre as tendências temporais ou previsão de sua distribuição no futuro. Esse conhecimento é importante para as organizações de trabalhadores ao contribuir para a identificação de respostas às suas necessidades de saúde, para a implementação de estratégias de prevenção e promoção em saúde de parte das instituições de saúde e de proteção social.Objetivos: Esta tese tem como objetivos: 1) estimar o coeficiente de mortalidade por mesotelioma e sua distribuição sócio-demográfica e temporal na Argentina, para o período 1980-2013; 2) identificar o efeito de idade, período e coorte na taxa de mortalidade por mesotelioma na Argentina, entre 1980 e 2013; 3) estimar o número de óbitos e coeficiente de mortalidade por mesotelioma para o período 2014 até 2023, na Argentina. Métodos: Este é um estudo de mortalidade conduzido com a população de 15 ou mais anos de idade, empregando dados do Sistema de Informações sobre Mortalidade do Ministério da Saúde da Argentina. Dados populacionais foram obtidos do Instituto Nacional de Estadística y Censos, do Ministério de Economia da Argentina. O mesotelioma corresponde aos códigos da Classificação Internacional de Doenças, CID, 9ª revisão, CID-9, 163.0, 163.1, 163.8, 163.9, para 1980 a 1996; e C45.0, C45.1, C45.2, C45.7, C45.9 para o período de 1997 a 2013, CID-10, para a causa básica de morte, respectivamente. Foram realizadas análises descritivas com frequências simples e relativas, estimaram-se os coeficientes de mortalidade por mesotelioma brutos e padronizados por idade pelo método indireto e a taxa de mortalidade empregando-se pessoa-ano. Em seguida, foi empregado o modelo de Lee Carter e método ARIMA para projetar o número e coeficiente de mortalidade por mesotelioma por idade e sexo para os anos 2014-2023...

Abstract:
Cities around the globe try to alleviate congested traffic, especially in economically fast growing cities. In order to help maintain this economic growth, cities must make alleviating congested traffic a priority. The purpose of this paper is to study the traffic problem in Riyadh city in Saudi Arabia and propose a solution. This paper will begin with a brief background about the city and then explain the problem. Afterward, the requirements of the new system will be discussed. Next, using analysis of alternatives, different solutions will be explored and through trade study, some of those alternatives will be chosen to be a part of the new system. Systems Architecture will be used to help readers visualize the current and future systems and in the modeling section, the results of a survey regarding the traffic problem in Riyadh are taken into consideration. This will be combined with a discussion on queuing and forecasting methods. The project is looked at from a Lean point of view to try and minimize waste within traffic administrations by suggesting a new organizational chart. Finally, ethics and risk managements are discussed. The goal of the document is to explore the traffic problem in Riyadh in hopes of finding a solution.

Abstract:
Uber Technologies Inc., empresa internacional fundada en 2009, basa su desarrollo en la economía colaborativa, conectando a conductores y usuarios a través de una plataforma virtual para realizar el servicio de transporte. Es así que en el presente documento se propone el planeamiento estratégico de Uber para los años 2019-2023, con el objetivo central de plantear los principales lineamientos y estrategias en el corto, mediano y largo plazo, orientados al crecimiento, expansión y obtención de rentabilidad, reforzando la posición interna de Uber para hacer frente a los eventos negativos que surjan y que constituyan una amenaza en su operatividad. Los objetivos estratégicos propuestos se analizarán a detalle en cada plan funcional: marketing, operaciones, recursos humanos, responsabilidad social y finanzas. Luego del trabajo realizado, se concluye que, con las ventajas competitivas que posee Uber (valor de la marca e innovación constante), puede hacer frente a las oportunidades de crecimiento económico. Su innovación constante le ha permitido brindar un servicio de mejor calidad y cubrir nuevos nichos de mercado, desatendidos por el servicio de taxis tradicional. Es esta misma innovación la que ha generado reconocimiento y aceptación por parte de los usuarios, incrementado el valor de la marca en el tiempo. Sin embargo, para llevar a cabo las acciones que se plantean, es necesario optimizar los recursos existentes a través de una mejor gestión, para mantener su liderazgo en Estados Unidos y a nivel global.

Abstract:
Photodissociation regions (PDRs) are described in the context of the interstellar medium and star-forming regions. Observations of PDRs and molecular hydrogen are reviewed and the reflection nebula NGC 2023 is discussed in detail. NGC 2023 is a bright and well-studied reflection nebula at a distance of 450 parsecs in the Orion region. Illuminated primarily by a B-type star, it offers an ideal opportunity to study UV-excited molecular hydrogen. The theory of the hydrogen molecule is described: the energy states and their relationship with the quantum numbers which represent the vibratinal and rotational states of the molecule, the radiative processes which determine the optical and infrared emission spectrum of H2, the effect collisions have on the excited states of the molecule and the processes which govern the formation and destruction of H2. Particular attention is given to the process of formation on the surface of dust grains and the resulting energy states of the ejected H2 molecule. Infrared and optical far-red observations of fluorescent H2 line emission from NGC 2023 are presented. The resulting datasets contain flux measurements of over ninety lines. These are combined with published data to produce column densities for 81 energy states of the H2 molecule, the most extensive dataset yet compiled for a PDR. The process of observing in the infrared red optical wavelength regimes are outlined. The emission lines of H2 are intrinsically very faint and thus measurements require careful data reduction to minimise sources of noise wherever possible. The data reduction steps which were applied to observations are described in detail. An optical extinction of Av = 5.7 ? 0.5 to the H2 emission region and ortho/para abundance ratio of 2.0 ± 0.2 are derived from flux ratios of emission lines and by minimising the scatter on a diagram which plots the logarithm of the column density against the energy level of each state.

Arbetet avhandlar vettingens framtida utveckling inom den kommande tioårsperioden(2013-2023), baserat på kvalitativa intervjuer med erfarna, väl insatta personer i tankochvettingbranschen. Intervjusvaren analyseras i diskussionsdelen och ger läsaren enbild av hur vettingen kan tänkas se ut om tio år, och hur vettingen kan förändras för atteffektiviseras ytterligare. Vettingen kommer troligtvis öka i omfattning under dennakommande tioårsperiod, med ökat antal arbetstimmar och ökad resursåtgång som följd.Antalet inspektioner kommer troligen att öka, både i antal och även tidsåtgången perinspektion kommer att öka. Ett införande av SIRE-vetting fullt ut är troligtvis inte attvänta, på grund av oljebolagens oförmåga att enas om var fokus skall ligga vid eninspektion. Fokus vid en inspektion kan komma att skiftas, troligtvis från kontroll avteknisk hårdvara och certifikat, till att se till fartyget som helhet, och i störreutsträckning utvärdera besättningen och dess kompetens.

La presente tesis ha desarrollado el Planeamiento Estratégico para Transportes León del Sur en función al Modelo Secuencial del Proceso Estratégico propuesto por D’Alessio (2016). Transportes León del Sur es una empresa que nace en la ciudad de Arequipa en 1985 y que actualmente brinda el servicio de transporte interprovincial de pasajeros y el servicio de envío de encomiendas. La empresa opera en 16 rutas a nivel nacional y centra sus operaciones en el sur del país. Se ha propuesto como visión para la empresa que para 2023 esta será una de las diez principales empresas de transporte terrestre de pasajeros en el Perú en nivel de ventas, actuando de manera socialmente responsable, generando rentabilidad para los accionistas buscando la satisfacción del cliente y manteniendo un compromiso con la seguridad, respetando las normativas legales que contribuyen al crecimiento del Perú. Asimismo, la misión propuesta para Transportes León del Sur es que la empresa busca conectar a las personas con sus destinos alrededor del territorio nacional; trabajando responsablemente por la calidad de su servicio y la seguridad, cuidando el impacto en la comunidad y el medio empleando una flota moderna con tecnología ecoeficiente, operando siempre comprometidos con el crecimiento del país y el bienestar de todos nuestros stakeholders; siendo la diferenciación ante sus competidores su principal ventaja competitiva. Finalmente, como resultado del Planeamiento Estratégico para Transportes León del Sur, se plantearon cuatro objetivos a largo plazo, se formularon 21 estrategias y se diseñaron 15 objetivos de corto plazo, los cuales han sido plasmados en el Tablero de Control Balanceado, herramienta que permite medir el logro de dichos objetivos.
This thesis has developed the Strategic Planning for Transportes León del Sur based on the Sequential Model of the Strategic Process proposed by D’Alessio (2016). Transportes León del Sur is a company that was born in Arequipa in 1985 and currently provides the interprovincial passenger transport service and the parcel delivery service. The company operates on 16 routes nationwide and focuses its operations in the south of Peru. It has been proposed as a vision for the company that by 2023 this will be one of the ten main passenger land transport companies in Peru in terms of sales, acting in a socially responsible manner, generating profitability for shareholders seeking customer satisfaction and maintaining a commitment to security, respecting the legal regulations that contribute to the growth of Peru. Likewise, the proposed mission for Transportes León del Sur is that the company seeks to connect people with their destinations around the national territory; working responsibly for the quality of its service and security, taking care of the impact on the community and the environment using a modern fleet with eco-efficient technology, always operating committed to the country's growth and the well-being of all our stakeholders; being the differentiation before its competitors, its main competitive advantage. Finally, as a result of the Strategic Planning for Transportation León del Sur, four long-term objectives were raised, 21 strategies were formulated and 15 short-term objectives were designed, which have been embodied in the Balanced Score Card, a tool that allows measuring the achievement of these objectives.

Yang, Kyoung-Eun. "A structuralist account of the theory-change from Newtonian to Einsteinian physics." Thesis, London School of Economics and Political Science (University of London), 2008. http://etheses.lse.ac.uk/2023/.

Full text
Abstract:
Some philosophers - such as Popper and Kuhn - have cited the theory-shift from Newtonian to Einsteinian physics as one of the great scientific revolutions. This thesis argues against this that the shift was 'evolutionary' and exhibits a high degree of continuity (or quasi-continuity). I will develop a view that selects the relationships between events - one specified by dynamical laws at issue - as the essential elements within these two physical theoretical frameworks. This view brings together the dynamical perspective of space-time (developed by Harvey Brown, Robert DiSalle and Nick Huggett) and structuralism (developed by Henri Poincare and Pierre Duhem, and more recently resuscitated by John Worrall). The former view turns our attention away from the structure of space-time to the dynamical laws. While the second view will clarify to what extent the theory-change is evolutionary. The thesis consists of five chapters. The first chapter discusses the failures of existing views on the theory-change. The second chapter develops my own positive view - building, as indicated, on the work of the two aforementioned perspectives. The third and fourth chapters consider detailed aspects of the particular theory-change from Newtonian to Einsteinian physics from the point of view. The final chapter discusses the strengths of my view in comparison to the existing accounts of the theory-change.

Dryburgh, Gillian. "Bifurcation and vibration of a surface-coated elastic block under flexure." Thesis, University of Glasgow, 1999. http://theses.gla.ac.uk/2023/.

Full text
Abstract:
The behaviour of a surface-coated rectangular, non-linearly elastic block subject to (plane-strain) flexure is investigated in this thesis. We consider a rectangular block of incompressible, isotropic elastic material coated with a thin elastic film on part of its boundary. Initially, the bulk material undergoes a non-homogeneous deformation and the equilibrium of the coated body is examined on the basis of the elastic surface coating theory derived by Steigmann and Ogden (1997a). Incremental displacements are then superimposed on the finitely deformed configuration in order to study possible bifurcation of the deformed block. Numerical bifurcation results pertaining to two particular strain-energy functions (for the bulk material) and a general energy function (for the coating material) are subsequently obtained. These results allow the influence of the surface coating on the bifurcation behaviour of the block to be determined and assessed with reference to corresponding results for an uncoated block. Next, use is made of the dynamic equivalent of the static surface coating theory, developed by Ogden and Steigmann (1999), to establish incremental equations of motion for the coated block. Corresponding incremental governing equations for an uncoated, pre-flexed block then emerge as a special case. The resulting frequency equations are solved numerically, again on specialization of the form of strain-energy function. The numerical vibration results then provide evidence of the effect of surface coating on the dynamic behaviour of the considered coated block relative to the uncoated case. Finally, we turn our attention to the (non-linear) shear responses of bonded elastic bodies. We examine the plane-strain problem of a rectangular compressible isotropic elastic block bonded to two rigid parallel plates. The deformation behaviour of the block is described by applying minimum energy and maximum complementary energy principles to obtain upper and lower bounds on the shear stress-strain relationship. Although maximum and minimum principles are not generally justifiable in non-linear elasticity we show that under certain conditions they are applicable and, for a particular form of strain-energy function, derive explicit energy bounds which we illustrate graphically.

Abstract:
Housing choice behaviour is made up of a wide array of dynamic individual level behaviour which can be recreated and explored using agent-based modelling (ABM). In the UK, there has been a renewed focus on urban regeneration policies over the past decade by the national government. Such policies seek to deal with the problems of deprivation in communities segregated by socioeconomic status. Using the case study district of East and South Easel Leeds (EASEL), an area known to have pockets of disadvantaged communities, the impacts of regeneration policy will be explored. A computer simulation of residential mobility and regeneration policy is created, in this way, the potential outcomes of regeneration schemes are explored.

Damnet, Anamai. "Enhancing acquisition of intercultural nonverbal competence : Thai English as a foreign language learners and the use of contemporary English language films." Thesis, full-text, 2008. https://vuir.vu.edu.au/2023/.

Full text
Abstract:
This study investigates aspects of the teaching and learning of intercultural nonverbal competence by university students majoring in English in Thailand and starts from the position that intercultural nonverbal competence is an important, but neglected area within English language teaching for international communication. Five aspects of nonverbal communication where there are pronounced differences between Thai and native English norms are investigated: facial expressions, eye contact and gaze, bodily communication, kinesics (touching), and vocalic communication. The study employs a range of qualitative and quantitative approaches in conducting classroom research on the learning and teaching of nonverbal communication within university EFL speaking and listening skills classes. Seventy-three second year undergraduate students majoring in English were randomly assigned to and participated in one of two different teaching interventions both of which involved the use of the same four American and Australian contemporary films. The experimental intervention involved explicit teaching of nonverbal communication and the other more traditional one provided exposure to the same native speaker interactions in the same four films, but with classroom activities focused on linguistic and pragmatic features arising from the films. Adopting a quasi-experimental pre and posttest design the study includes three phases of data collection: (1) pre teaching assessment, (2) teaching phase, and (3) post teaching assessment. The pre and post teaching assessments cover students’ attitudes towards, understanding of and ability to employ nonverbal communication when communicating in English in intercultural contexts. The post teaching assessment covers these same areas together with additional qualitative data collection about students’ experiences of participation in the study. Data analyses include use of analysis of covariance (ANCOVA) and multivariate analysis of covariance (MANCOVA) and within group t-tests. The study reveals that in comparison with students from the control group students from the experimental group who had participated in the explicit teaching of nonverbal communication had: (a) more positive attitudes towards nonverbal communication of English native speakers, (b) a higher level of understanding of nonverbal communication of English native speakers (c) a higher level of ability to apply nonverbal channels in communication appropriately in role playing interaction with an English native speaker, and, in addition, (d) most students from both groups felt positive about the opportunities that practising role plays and viewing contemporary English language films provided for them to enhance their intercultural acquisition of nonverbal competence in communicating in English with native speakers. Qualitative data supported the quantitative findings and also indicated that students in the experimental group had achieved a deeper and more explicit understanding of the role of nonverbal communication in interactions in English, whilst also demonstrating a strong sense of what might be acceptable in an English language context with English native speakers and what is acceptable with fellow Thais. Furthermore, the results highlight that it is not essential for nonnative speakers to stay/study abroad in English as native language speaking countries in order to improve their communicative and intercultural nonverbal competences to levels approximating that of native speakers. Films and role play, when used appropriately, may provide effective native speaker modeling and opportunities for practice.

Abstract:
Denna studie undersöker ett av Uppsala kommuns etappmål inom klimat- och miljöarbete och hur den kommunala målstyrningen påverkar gymnasieskola och anställdas interna arbete. För att analysera det organisatoriska arbetet och implementeringar av målet används teorier kring neoliberalism och new public management (NPM). Till studien har textanalys och semistrukturerade intervjuer genomförts. Resultatet indikerar att målträngsel är ett faktum för skolans verksamheter vilket även påverkar implementeringen och hanteringen av ekomålet. Hur det påverkar de anställda beror mycket på individens kunskap och ansvarsområde. Skolans storlek har stor betydelse på tillämpningen av målet och arbetsbelastningen på ansvarig personal. Vidare visar studien på att den kommunala styrningen både medför en hårdare intern styrning inom verksamheterna samtidigt som utrymmet för ledarskap kan tyckas öka.

Abstract:
Esta investigación tiene como objeto el estudio del legado teórico y arquitectónico de Joan Rubió i Bellver (Reus, 1870 - Barcelona, 1952) en el contexto mallorquín. Rubió i Bellver acompañó a su maestro, Antoni Gaudí, a Palma de Mallorca para colaborar con él en las obras de reforma de la Seu. A partir de esa circunstancia se forja una relación muy especial con la isla que derivará en una retroalimentación fundamental para ambas partes. Esta colaboración fue el punto de partida para desarrollar toda otra serie de proyectos diseminados alrededor de la isla; la revisión del catálogo de todas esas obras que dejó en Mallorca constituye uno de los retos importantes del presente estudio.

Rubió se convirtió en el principal embajador del gaudinismo en la isla de Mallorca. Mediante todos los proyectos que Rubió dejó repartidos por la isla estaba contribuyendo a la difusión de la nueva arquitectura creada por su maestro, Antoni Gaudí. No sólo contó para estos cometidos con la ayuda de alguno de sus frecuentes colaboradores y amigos catalanes, sino que actuó de acuerdo a unas pautas que como referente último tendrían a Gaudí. Si bien es cierto que otros catalanes pasaron por la isla, véase Domènech i Montaner o Madorell, es nuestro arquitecto quien se involucró más en la idiosincrasia y el contexto mallorquín del momento, convirtiéndose en el arquitecto modernista catalán con más obra en Mallorca.

La presente investigación analiza la presencia de Rubió en Mallorca como una estrategia de un grupo reducido de intelectuales -fundamentalmente religiosos- para vincularse a Cataluña y hacerse partícipes del sentimiento nacionalista tan ferviente en aquellos años. Figuras como el obispo Campins o el vicario general Alcover son fundamentales en los encargos que Rubió recibe en la isla respondiendo esto, en última instancia, a un movimiento deliberado con los propósitos arriba mencionados. La presencia de Rubió en lugares de la isla a priori inconexos y, si cabe, algo insólitos, respondería a esta estudiada estrategia de los religiosos.

Tal vez sea su faceta como teórico aquella más desconocida, sorprendiendo muy especialmente el hecho de que, directa o indirectamente, con frecuencia aparece vinculada a Mallorca. Prácticamente un tercio del volumen de sus textos tienen como objeto algún tema o arquitectura de la isla. Varios de estos escritos fueron publicados, además, en diarios mallorquines. Dentro de todo este legado escrito interesan muy especialmente las aportaciones que se refieren al gótico meridional, siendo uno de los primeros en tomar conciencia de unas diferencias estilísticas con respecto al más popular gótico nórdico. Cabe entender estas reflexiones como parte de su sentir nacionalista y de su continua búsqueda de unas raíces comunes en todos lo países catalanes. Estas conclusiones las extrae, en su mayoría, a propósito de las exhaustivas y rigurosas investigaciones que lleva a cabo en la catedral de Mallorca, convirtiéndose estas también en estudios sin precedentes y esenciales para el conocimiento de este templo. El legado teórico de Rubió es lo que traduce más claramente su personalidad e ideología, siendo esencial para la óptima comprensión de sus arquitecturas. Su paso por Mallorca y, en especial todas sus reflexiones y estudios que de esta derivaron son fundamentales para comprender la trayectoria profesional de Rubió como arquitecto.
"Joan Rubió i Bellver in Mallorca.
Architecture and Theory

TEXT:

The aim of this research is the study of the theoretical and architectural legacy of Joan Rubió i Bellver (Reus, 1879 - Barcelona, 1952) in Mallorca. Rubió I Bellver went to Palma de Mallorca with his master, Antoni Gaudí, to collaborate with him in the works of La Seu. This collaboration set up the start for the development of a series of projects that were carried out around the island; the revision of the catalogue of all the works he left in Mallorca, is one of the most important challenges of this study.

This research analyses the presence of Rubio in Mallorca as a result of a strategy of a reduced group of intellectuals, mainly religious, in order to be related to Cataluña and take part of the nationalism that was a strong and determinant feeling at that time. Figures as the bishop Campins or the General Vicar Alcover, played an extremely important roll in involving Rubio in different projects in Mallorca.

His work as theoretician, is probably the less known side of Rubio, and specially surprising is the fact that directly or indirectly it is frequently related to Mallorca. Nearly a third of his writing is based on the architecture or other subjects of interest in the island. Moreover, several of these articles were published in newspapers of Mallorca.

Within all this written legacy, the most interesting are those referred to the Southern Gothic, being Rubió one of the pioneer in clearly establishing the differences between the above mentioned style and the most popular Northern Gothic. His statements were likely due to his nationalism and his constant research of a common identifier in all of the Catalonian Countries.

The majority of his conclusions were based on the exhaustive and rigorous research he carried out in the Cathedral of Mallorca, which became essential for the further knowledge of the temple. His work in Mallorca, and mainly his conclusions and consequents studies are of the most importance in order to understand the professional performance of Rubió as architect.

Abstract:
The purpose of this study was to examine formal and informal networks within the South Florida Colombian community. The qualitative, ethnographic study used research from personal interviews, focus groups, and observations, placed within a theoretical framework based predominantly on Putnam’s conceptualization of social capital, as well as previous research on immigrant and Colombian communities. The resulting analysis focused on Colombian immigrant solidarity and social capital in South Florida, examining the role of the context of reception and the effects of social structures on levels of trust and reciprocity. The results showed that a non-receptive immigration policy, socio-economic differentiation in migration waves, and spatial fragmentation within the receiving community, hinder community-building. There were incipient signs of civic engagement, yet Colombian leadership as well as individual Colombians perceived that the community lacked solidarity. Both formal and informal networks are best characterized as fragmented and guided by pre-existing social structures. The findings showed that a unique context of arrival and low levels of social capital have challenged Colombian immigrants’ ability to create the type of community cohesion that would facilitate their transition to life in South Florida.

Abstract:
Composite materials together with adhesive-bonding have been increasingly used in the aviation industry. Delamination is among the critical failure modes in fiber-reinforced laminated composite structures including adhesive-bonded assemblies. This thesis presents an analytical approach by taking into account the first-ply failure in adhesive-bonded composite joints subjected to axial tension. The ASTM D3165 standard test specimen geometry is followed for model development derivations. The field equations, in terms of displacements within the joint, are formulated by using the first-order, shear-deformable, laminated plate theory together with kinematics relations and force equilibrium conditions. The stress distributions for the adherends and adhesive are determined after the appropriate boundary and loading conditions are applied and the equations for the field displacements are solved. The equivalent forces at the tip of the prescribed interlaminar crack are obtained based on interlaminar stress distributions. The strain energy release rate of the crack is then determined by using the virtual crack closure technique (VCCT). The system of second-order differential field equations is solved to provide the adherend and adhesive stresses using the symbolic computation tool, Maple 9.52. Finite element analyses using the J-integral as well as the VCCT are performed to verify the developed analytical model. Finite element analyses are conducted using the commercial finite element analysis software ABAQUS 6.5-1. Results determined using the analytical method are shown to correlate well with the results from the finite element analyses.

Full text
Abstract:
This is a study of the design and development of an Organisational Software Package (OSP). It particularly focuses on the ambitions and supplier strategy of building a ‘generic software solution’ (i.e., a software system that in principle can be used by everyone). The study is located in the distinctive context provided by China, with its particular history and in a period of rapid economic reform. The starting point of this research is the apparent empirical and theoretical gap in the social study of Organisational Software Packages, in which the construction of standard solutions and the supply side of the technology's story have been largely overlooked. Moving beyond conventional information system design perspectives, this thesis draws upon concepts developed within the Social Shaping of Technology (SST) perspective, adopting an interdisciplinary approach to analyse the creation and evolution of OSPs, which enables us to address both the dynamism and continuity of these developments. In order to avoid the shortcomings of snapshot studies, we applied the concepts of ‘social learning’ and in particular the ‘biography’ of software package to examine the evolution of the OSP supply as the supplier developed its product and market strategy over a number of product cycles. Lastly, we applied Rip’s (Rip and Kemp 1998) technological transitional model to explore the influence of both the broad socio-economic context and institutional arrangements on the OSPs' development, as well as the contribution of these and related changes to changing the setting of technology. Methodologically, an extremely detailed longitudinal and contextual analysis has been undertaken through a qualitative historical case study of the evolution of a Chinese software package from 1998- 2005 in the context of China, triangulating different methods: interviewing, document analysis and participant observation. The empirical findings of this study firstly show that achieving the ‘generic’ is not an impossible goal but is rather an evolutionary process which is filled with struggles and tensions. OSP suppliers are forced to maintain a strategic balance between a range of contextual factors with technical, financial and social dimensions. Secondly, and perhaps the key contribution of this study, is the complex multi-locus and multi-layered account it offers of the OSP innovation process, according to which the supplier learns about the representation of users and use in both ‘local’ and ‘community design’ spaces with different approaches and foci through interaction with user organisations and other social players. The findings show that OSP suppliers are required to readjust their relationships with user organisations and establish cycles that move between seeking to achieve the economic imperative through standardisation and seeking to accommodate local user requirements. Thirdly, while this empirical study confirms some observations that have been made about packaged OSP production in western countries, it also reveals some specifically Chinese characters. These particular features of the development process which were identified in the Chinese PDM development were framed (using the terminology of Rip’s transitional model) by the unstable landscape and socio-technical regimes. Finally, this case study also throws light on the applicability of SST in developing countries and on the policy and practice of China’s future technology development.

Full text
Abstract:
Traditionally, fish oil (FO) has been used extensively in aquafeeds. The stagnation in global fish oil production coupled with an increased demand for its use in aquaculture feeds, especially salmonid feeds, has greatly inflated fish oil prices. Therefore, in order to sustain the rapid growth of the tilapia industry, the dependence on these commodities in feeds should be reduced through use of cheaper and more sustainable sources of dietary lipids, such as palm oil. This study therefore investigated several, previously poorly understood, effects of palm oil on reproductive performance of the commercial tilapia species, Oreochromis niloticus; which currently ranks as second most popular species in world aquaculture. In the present study broodstock were fed on experimental diets at full and half ration regimes throughout their entire life cycle from exogenous feeding. Studies were conducted in standardised and controlled hatchery conditions, thereby reducing the potential influence of environmental variations. First feeding O. niloticus fry were fed on four diets, cod liver oil (D 1), palm oil (D 2), mixed palm and cod liver oil (D 3) (9:1 ration) and a commercial trout diet as control (D 4) (Skretting, U.K.) on a reducing ration based on fish size. The present study investigated the effect of dietary lipid sources on (1) growth performance, (2) biochemical composition of eggs (total lipid and fatty acid composition), (3) morphological parameters of eggs (total and relative fecundity, egg size, egg weight and EW:BW), (4) larval quality (larval length and weight) and (5) oocyte recruitment and its associated sex steroid hormones. Experimental diets and feeding ration significantly influenced (p<0.05) the growth performance over a period of 120 days. Total lipid and fatty acid composition of eggs originating from broodstock fed on palm oil, mixed palm and cod liver oil (9:1) or a control diet were not significantly different (P>0.05) when fed at either full (3% BWday-1) or half ration (1.5% BWday-1). The present study, however, confirmed that fatty acid composition of fish eggs reflected the fatty acid composition of the diet, although specific fatty acids were selectively utilized or retained in the eggs. The mean inter-spawning interval (ISI) increased with increasing fish size and averaged 14, 19 and 24 days for fish fed on palm oil, mixed palm and cod liver oil or control diets, respectively. The shortest ISI observed was 7 days for fish fed a palm oil diet. Total fecundity ranged from 660 - 820 eggs/clutch. Mean total fecundity was 750, 820 and 660 eggs/clutch for fish fed a palm, mixed palm and cod liver oil or a control diet, respectively, but these differences were not significant (P>0.05). However, relative fecundity and egg weight to body weight rates as a percentage (EW: BW) were found significantly differ (p<0.05) between fish fed the control diet and experimental diets. Mean egg diameter (2.2 mm) was not significantly influenced (p>0.05) by experimental diets. The egg volume, egg dry and wet weight, fertilisation and hatching rate were also not significantly different between fish fed the experimental diets. Oocyte development was classified into distinct stages based upon oocyte size, biochemical properties and structure. The recrudescence to these stages was not significantly influenced by broodstock fed experimental diets either at full or half ration. Steroid hormones and histological analyses provided valuable data concerning the oocyte development and recruitment in this species. Levels of 17ß-oestradiol (E2) and testosterone (T) peaked within 6 days of spawning, suggesting that vitellogenesis began as early as day 2 or 3 post-spawning. By day 6, ovaries were dominated by large late-vitellogenic/maturing oocytes (stages 6 & 7) occupying about 70% of the ovary. Gonadosomatic index (GSI) reached maximal levels by day 6. It is suggested that pre-vitellogenic oocytes are recruited into vitellogenic growth immediately after spawning and complete vitellogenesis on day 6 post-spawning. Finally, the present study investigated the effect of food restriction at two rations (full and half) on broodstock reproductive performance. Oreochromis niloticus were rationed from first feeding and throughout their life-cycle. The dietary regime, full ration (3%) and half ration (1.5%), influenced fish size but despite this variation no significant differences (p>0.05) were detected in total lipid and fatty acid composition in the eggs, total fecundity, egg diameter, total egg volume and larval size. These results suggested that despite large differences in food availability throughout their life cycle, investment in reproduction had remained remarkably consistent. It appeared that during food restriction, O. niloticus sacrificed body weight and growth so as to maintain reproductive investment. In summary, this study provides valuable information using a novel experimental design on the effects of dietary lipid sources on reproductive performance of female O. niloticus. Substituting palm oil for fish oil as the dietary lipid source and reducing ration by half (1.5% BWday-1) had no significant effect on reproductive performance. Therefore it is suggested that under controlled conditions, lipids of non-marine origin, such as palm oil, can be successfully substituted for broodstock diets. Halving feed requirement should also increase profitability of seed production. KEYWORDS: Tilapia; O. niloticus; palm oil; diet; fecundity; spawning periodicity; oocyte recruitment; reproductive performance.

Full text
Abstract:
Since Boyer's (1990) seminal publication on scholarship there has been a steadily expanding body of knowledge concerned with reviewing the priorities of the professoriate in higher education (HE). This dissertation enters that discourse by exploring HE educators' perceptions of Boyer's (1990) multiple dimensions of scholarship. It also accepts the challenge offered by Schon (1996) that examination of the new dimensions of scholarship requires a new epistemology by designing and employing a spiral methodology. This twofold task forms the basis of this dissertation. This investigation is contextually located in an education department in a large university in the United States of America. It delves into the opinions of educators as they relate to scholarly practices, and the influence of the institutional ideology embedded in the structure of HE in today's modem universities. The study then focuses on the scholarship of teaching and learning (SoTL) and renders problematic the proposed assessment standard of reflective practice. The use of my spiral methodology in action opens up both the framework and the theoretical structure for critical examination. It reveals, through the praxis how the phased structure has allowed the research project to extend into using such diverse research methods as an email survey, interviews through conversations and autoethnography. This study offers contributions in two distinct areas. Firstly, the investigation into educators' perceptions of scholarship revealed four important issues: • a strong desire to see the definitions expanded • that the SoTL is a contested and poorly understood dimension • the rhetoric of reflective practice is often very different to the practice • the ideology and epistemology of the institution dictate the priorities Secondly, the spiral methodology which holds reflexivity as a central tenet proved capable of offering a sensitive, flexible, interconnected framework within which to conduct research in the complex and context bound environment of research in educational settings. There are a number of potential future directions that could be developed from my research some of which include: • investigating institutional commitment to implementing campus changes • the impact of proposed changes on the student population • examining the contested meaning of reflective practice in theory and practice • further development of a reflexive spiral methodology • expansion of the combination of critical analysis and boundary conversations This dissertation should be read both as a very personal sequential journey into researching, and as a growing understanding of the research topics. This evolution has led to altering some of my early methodological claims and demonstrates my commitment to an open and honest account.

Abstract:
Fibre-reinforced dental resin composites (FRCs) have shown increased fracture resistance and tensile strength compared with particulate filled composites (PFC). However, clinically successful restorative materials require adequate bond strength and wear resistance along with high strength. An experimental FRC (ST) was developed and tested as a dentine replacement. It has randomly distributed E-glass fibres above their critical length of 0.5-1.6 mm. This work aimed to evaluate the possibility of using ST as a single restorative material by assessing its three-body wear resistance and surface contact fatigue. The polymerisation shrinkage, water sorption, and bond strength of ST were also assessed. Two commercially available materials; an FRC (Build It FR) and PFC (Z250) were used as comparators. ST showed significantly lower wear resistance and higher contact fatigue. No significant difference was found regarding polymerisation shrinkage but ST had significantly higher water sorption, lower shear bond strength (SBS) to human dentine. SBS of the interfacial layers within and between the dental resin composites was evaluated after 24 hours and 1 year of water storage in the absence of an oxygen inhibition layer. Build It/Z250 showed a significantly higher SBS at both time intervals. The presence of an oxygen inhibited layer increased the interfacial strength in all groups except ST/Z250. ST formulations were varied in resin/diluent (Bis-GMA/TEGDMA) ratios, filler loading and fibre lengths for development. Wear testing found changing the Bis-GMA/TEGDMA ratio from 60/40 to 70/30 decreased the wear resistance regardless of filler loading and fibre length. In summary, wear resistance of ST and its variants was insufficient to recommend its use as a single restorative material without a surface veneer of PFC. As a dentine replacement, ST was only comparable with Z250 and Build It in polymerisation shrinkage and SBS between composites in the absence of an oxygen inhibition layer.

O objectivo deste trabalho é a melhoria do processo da Unidade Piloto de Reciclagem de Resíduos de Construção e Demolição instalada em Montemor-o-Novo. A Unidade tem uma capacidade instalada para produção de agregados reciclados de 50 a 80 t/h, apresentando como etapas de processamento: fragmentação, separação magnética e crivagem. Numa perspectiva de conhecer os contaminantes existentes nos Resíduos de Construção e Demolição (RCD) que chegam à Unidade, procedeu-se à caracterização (separação manual) dos contaminantes presentes por produtor. Com vista à melhoria da qualidade do processo de reciclagem, estuda-se a eficiência da operação de separação magnética, por variação da distância entre a tela transportadora e o separador magnético. A aplicabilidade dos agregados reciclados constitui a terceira fase do estudo, em que se efectua a análise granulométrica dos agregados reciclados de tout-venant (produzidos com abertura fixa da goela do moinho) e calibrados (por crivos de barras), para verificar/comprovar a sua distribuição real, passando-se depois à caracterização dos contaminantes nesses agregados, por separação manual, magnética e por densidades. Os resultados revelam que a percentagem de contaminantes nos RCD é bastante baixa, sendo a madeira o contaminante presente em maior quantidade. A eficiência do separador magnético demonstra que esta diminui bastante para distâncias superiores a 27cm. A análise granulométrica revela que os agregados reciclados de tout-venant não são adequados a aplicação em sub-base de estradas. Nos agregados calibrados, a percentagem de material dentro da classe granulométrica desejada é geralmente baixa, devido ao uso de crivos de barras. Nos agregados reciclados, os contaminantes mais significativos são o material magnético e cortiça.

From this year on, Guarda has a repository to its sources of documental information, which were lost by various institutions of public administration, or on the custody of personalities, whose character made them more aware of their importance and therefore kept them. The oldest collections stored in its deposits go back to the seventeenth century, but these are not the only ones contributing to the historical memory of the city, the building in which the archival facilities operate is, itself, a living source of Guarda’s inhabitants memory. The director and the other staff of the Archive strive to promote the archival heritage through the implementation of various activities and compliance with the various services required by the clients, who search for knowledge and are each time more demanding. This has leaded to rethink the whole archivist theory practiced, until now, all over the world. Information and Communication Technologies represent a reality in the archives’ systems because they allow a search and retrieval of information without being necessary to go to the place where it is stored.

Actualmente, a Contabilidade Pública constitui uma das matérias que vem despertando um grande interesse para académicos e profissionais. Nos últimos anos, a Contabilidade Pública, em Portugal, sofreu profundas alterações, resultantes da Reforma Administrativa e Financeira do Estado e da implementação do Plano Oficial de Contabilidade Pública e planos sectoriais públicos, tendo em vista uma maior normalização e harmonização contabilística. Com a reforma da Contabilidade Pública passamos de um sistema de informação, de carácter eminentemente orçamental, direccionado para a prestação de contas e controlo da legalidade, para um sistema de informação orientado para a tomada de decisão. O grau de desenvolvimento atingido no âmbito do processo de normalização contabilística, na Administração Pública, carece ainda de novos desenvolvimentos. É objectivo geral deste estudo, tendo por base uma revisão bibliográfica, um inquérito direccionado a indivíduos relacionados, directa ou indirectamente, com a Contabilidade Pública e uma análise à prestação de contas de 2003 de alguns municípios portugueses, investigar e conhecer o estado actual da Contabilidade Pública e apresentar uma proposta de um plano de contabilidade pública único. A elaboração do plano proposto resultou da análise comparativa entre o plano oficial de contabilidade pública e os planos sectoriais públicos, do conhecimento, através da revisão da literatura e dos estudos empíricos, dos principais inconvenientes e limitações que os planos apresentam e das normas internacionais de contabilidade para o sector público emitidas, pelo International Federation of Accountants. Nowadays, Public Accounting is one of the subjects that rises more interest between researchers and professionals. In recent years, Public Accounting in Portugal has gone through several changes, resulting from the Reform of the Governmental Financial Administration, the implementation of the Chart of Accounts for the Public Accounting and the several governmental sectorial plans, aiming to achieve accounting normalisation and harmonisation. The reform of Public Accounting goes from an information system, mainly budgetary, directed to financial reporting and the control of legality, towards an information system decision-making oriented. The level of development reached, in what accounting normalisation process is concerned, in Administrative Public Sector, is far from new achievements. The main aim of this study, based on an extensive literature review, a survey with questionnaires applied to individuals directly or indirectly related to Public Accounting and an extensive analysis of several municipalities Financial Report from 2003, is to assess the present condition of Public Accounting and to produce an unique accounting plan. The resulting plan was obtained through a comparative analysis between the official plan for the governmental accounting, the several sectorial plans and the knowledge, through the referred literature review and survey, of the main inconvenients and limitations which the existing plans present but also through the International Accounting Standards for the public sector, issued by the International Federation of Accountants.

A presente pesquisa, realizada sob a forma de estudo de caso, objetiva caracterizar as relações existentes entre a estrutura e as estratégias no âmbito da Universidade Regional Integrada do Alto Uruguai e das Missões - URI. A URI caracteriza-se como uma universidade comunitária, multicampi, de característica eminentemente regional e integrada, originada da associação de Escolas Isoladas de Ensino Superior, localizada no Interior do Rio Grande do Sul, com Campi em Erechim, Santo Ângelo, Frederico Westphalen e Santiago, além de extensões em São Luiz Gonzaga e Cerro Largo. As estruturas foram estudadas utilizando-se as variáveis configuração estrutural, níveis de tomada de decisão e complexidade. Já as estratégias foram estudadas no sentido de identificar os tipos predominantes na organização e como estas são formadas. Caracterizada por uma gestão acadêmica única, embora com descentralização administrativa, o estudo conclui que a estratégia inicial de criação da universidade determinou a forma de organização estrutural, e que esta organização, que alocou substantiva autonomia para os Campi, configura-se como uma estrutura organizacional do tipo divisionalizada, com características de burocracia profissional do tipo racionalburocrática. As estratégias podem ser denominadas como do tipo guarda-chuva, em que as linhas gerais são deliberadas, e os detalhes passam a emergir no decorrer do percurso. O estudo propõe uma reconfiguração estrutural e estratégica que respeite as características de individualidade da organização, mas que consiga inseri-la numa perspectiva moderna de organização, buscando criar condições de inserção num novo momento, em que as organizações precisam ser menos hierarquizadas e mais inovativas.

Abstract:
Une bonne compréhension du cycle continental de l'eau est un enjeu crucial de la modélisation climatique. La mission de gravimétrie spatiale GRACE lancée en 2002 a permis pour la première fois de mesurer les variations temporelles de la gravité terrestre avec une résolution temporelle de l'ordre du mois. Sur le domaine continental, les variations temporelles de la gravité résultent principalement des redistributions saisonnières et interannuelles de masse d'eau dans les bassins fluviaux. Ainsi GRACE est un outil unique pour étudier le bilan d'eau dans les grands bassins fluviaux et le cycle continental de l'eau. Dans le présent travail de thèse, on a étudié les variations du stock d'eau total mesuré par GRACE dans les bassins fluviaux du continent sud-américain, en particulier dans le bassin amazonien. On a analysé les évolutions spatio-temporelles du stock d'eau dans chacun des sous bassins de l'Amazone, leur lien avec les données de hauteur d'eau in situ le long des cours d'eau et avec les précipitations. On a pu mettre en évidence la forte signature du phénomène ENSO sur l'hydrologie de ce bassin et la réponse du stock d'eau total à ce forçage. Dans une dernière partie, on a abordé la question de l'utilisation des données GRACE dans la modélisation hydrologique du sous bassin du Rio Negro. Les principales limitations de la modélisation actuelle ont été mises en évidence et on a discuté les perspectives d'améliorations futures
Understanding large scale water fluxes is a great challenge to be met when addressing climate modeling. Data from space gravimetry GRACE mission has been derived since 2002 for allowing a more precise determination of the Earth gravity field. Over the continents, main gravity changes taking place at the seasonal scale are due to the water cycle. Thus, since the planning phase GRACE data had been envisaged as a unique source of information on water cycle variability on large scale. This has been fully attested since its data became available for the scientific community. The present Ph. D. Thesis aims at discussing Total Water Storage (TWS) series derived from GRACE solutions suitability as an additional data source for large scale hydrological modeling. A great effort has been done in analyzing TWS spatiotemporal variability over large Brazilian watersheds, especially the Amazon basin. The obtained results show that GRACE TWS series could represent main water cycle characteristics at the seasonal and interannual scale. As a next step, the suitability of integrating GRACE TWS data has been addressed within a simple approach applied to the Negro River basin, one of the most important subbasins of Amazon watershed. From the obtained results many of the limitations in using these data for hydrological modeling purposes could be discussed, and a improved framework for analysis has then be proposed

Full text
Abstract:
Present day composite sandwich panels provide incredible strength. Their largest problem, however, is early bonding failure between the core and the skin. This is due to the low bonding surface area of present cores like honeycomb. Corrugated structures could provide a remedy for this with their much larger bonding surface area. Corrugated structures have extreme mechanical properties deeming them particularly useful in aerospace and automotive applications. However, previous research has shown that the stiffness of carbon fiber causes debonding and drastic failure when used as both a core and a skin. Bio-composites have properties that could strengthen the corrugated sandwich panel against such debonding and increase the strength of the structure while making it cheaper and more environmentally friendly. This thesis presents the optimum design, manufacturing, and testing of corrugated sandwich panel structures with integrated bio-composites under edgewise compression loading. To do this, optimum corrugation geometry was identified using theoretical analysis of the moment and bonding area of the shape. Control tests with carbon fiber and hemp were conducted. The bio-composite was integrated in both the core and the skin individually in corrugated sandwich panels. The cases tested were all-carbon fiber, hemp skin with carbon fiber core, carbon fiber skin with hemp core, and all-hemp. These corrugated structures were analyzed by conducting compression loading tests on varying lengths of single-ligament panels utilizing trapezoidal corrugation as the core and a flat plate as the skin. The lengths tested were 1, 2, 3, and 4 inches. As many samples as possible were manufactured out of limited material with heavier focus on creating the shorter samples. The goal of this testing was, first, to determine if hemp fibers were viable as a substitute for certain sections of the traditional composite structure, and second, to see if integrating hemp fibers would solve the problems of debonding seen in the all-carbon fiber samples seen in previous research. To determine mechanical property viability, the ultimate load and stiffness were investigated for each sample, as well as investigation of the failure modes seen in the test. Secondary goals were to see at what length buckling behavior became an issue and to see if this corrugated structure and all its failure modes could be simulated in finite element analysis. At the 1-inch and 2-inch lengths where minimal buckling was encountered, the hemp core-carbon skin samples showed better results than both the all-carbon fiber and the all-hemp samples with a 4% and 6% increase in average ultimate load and a 11% and 47% increase in stiffness, respectively. From these results, it was concluded that hybrid bio-composite structures can have comparable mechanical properties to traditional composites and can solve bonding failure.

Abstract:
My textile work is about noticing the beauty of natural creation from extreme perspectives. I reference the patchwork quality of landscapes by finding the lines, patterns and color fields in aerial photography and translating them into a textile medium. Looking at land and water from an airborne vantage point feels like reading a good poem. I can’t quite determine the precise meaning but the individual phrases and their arrangement in a composition send a shiver of pleasure up my spine. In the same way, I can’t exactly identify what I’m seeing from afar, but the beauty of the parts relating to the whole rings true. At the other end of the spectrum, I am fascinated with the idea that tiny particles assemble in millions to create those patches of land and riverbed threads. It strikes me that the microscopic, enclosed, underground or hidden elements are closely connected to the larger more overt images of nature. I can’t fully see the seeds within the pod’s protective shawl, nor the connecting trails of underground invertebrates. However, with close inspection and imagination, I suggest the shape and color, texture and trajectory of these agents of change.

Abstract:
The warfighter constantly needs increased accuracy from GPS and a means to increasing this accuracy to the decimeter level is a broadcast ephemeris message containing GPS satellite orbit and clock corrections. The ephemeris message is produced at the GPS MCS (Master Control Station) which receives GPS signal data from NGA and Air Force worldwide and uses sophisticated software to produce the orbit and clock corrections. The problem is getting the ephemeris message to the tactical user in a forward operating area. This thesis proposed a notional architecture for pushing the ephemeris message to the tactical user. It then modeled the architecture and simulated the broadcast of the ephemeris message to a tactical user using NETWARS. The baseline architecture was simulated and analyzed and then additional constraints were placed upon the network to simulate a real-world model. The simulation results demonstrated that the architecture was feasible for ephemeris message broadcast with the constraints on time intervals between broadcasts, residual traffic and message size.

Abstract:
The present study examined the effects of a brief video-led mindfulness exercise on momentary choice impulsivity as measured by a monetary delay discounting survey. Participants in the experimental group watched a video requiring them to engage in a brief breathing exercise while participants in the control group viewed a video unrelated to the topics at hand. Switch point analyses suggested that the experimental group discounted less steeply following the intervention while the discounting slope of the control group remained relatively unchanged. A t-test comparing the average change in AUC values from pre-test to post-test for both groups revealed a significant difference: t (13.17) = 2.94, p = 0.0114. The experimental group demonstrated greater changes in AUC scores from pretest to posttest (M= 0.1036 ± 0.0328) than the control group (-0.00031 ± 0.01317). Additionally, an F-test was conducted to compare variances between the individual score changes of the experimental group and the control group (p < .05). The results suggest that there was a significant difference between the two groups: F = 5.682, p = 0.0082. The results of this study could have several implications for future research regarding delay discounting and mindfulness as an intervention for impulsivity and suggest that telecommunication may be a viable modality.

Abstract:
The study sample was comprised of 18,953 subjects aged 18 years and older who participated in the Third National Health and Nutrition Examination Survey. Preference for diet soda over regular soda was higher in females as compared to males and in Caucasians as compared to other races. Mean alcohol consumption was almost three times higher in males than in females. Undiagnosed hypertension was more common in males than in females, in 65-90 than in 50-64 year olds, and in people with less than high school education compared to those with higher education. Diastolic pressure was correlated with the level of consumption of diet soda, coffee, tea, and alcohol. Diet soda and alcohol consumption had a statistically significant positive relationship with hypertension even after adjusting for demographic variables and body mass index. The study provides useful information of the patterns of beverage uses and the prevalence of hypertension in the United States.

Abstract:
Thesis (MTech (Food Technology))--Cape Peninsula University of Technology, 2012.
The expansion of the South African olive processing industry has brought an increased threat to the environment. More production activities lead to more wastewater generation that requires more costly treatment. Regulatory bodies concerned with the release of effluents into the environment are imposing evermore-restrictive guidelines. With this information in mind, the South African olive industry is facing a significant challenge of maintaining economic competitiveness while becoming more environmentally benign. To begin addressing this challenge, the olive processing industry must develop and implement new, more effective, tailored treatment technologies to remediate olive wastewater prior to its release into the environment. In this study, the use of indigenous olive wastewater biofilms in combination with a rotating biological contactor (RBC) was investigated for possible bioremediation purposes. The development of microbial biofilms resulted in the breakdown of the hazardous chemical compounds present in the olive wastewater, i.e. reducing the chemical oxygen demand (COD) and polyphenol content. Results showed that indigenous microorganisms within table olive and olive mill wastewater have a strong tendency to form biofilms. Furthermore, when these biofilms are applied to a small-scale RBC system, significant lower levels of both COD (on average 55% for table olive wastewater (TOWW) and 46% for olive mill wastewater (OMWW) and total phenol (on average 51% for TOWW and 39% for OMWW) were obtained. Results from shocking the biofilms with chemicals routinely used during olive processing indicates that most have a negative effect on the biofilm population, but that the biofilms are able to survive and recover in a relatively short time. This study confirms the potential application of indigenous biofilms found in olive wastewater streams for future bioremediation technologies that form the basis for the development of an eco-friendly, easy-to-manage, low cost technologies specifically designed for the small South African olive processing industry.

Full text
Abstract:
Although millions of individuals worldwide are affected by blinding retinal degenerative diseases, most have very few options for treatment and no hope for vision restoration. Induced pluripotent stem cell (iPSC) replacement therapies represent a promising treatment option, but their effectiveness is limited by an overall lack of physical support for injected cells. Stem cell scaffolds can be used to provide this support by serving as an attachment platform for cells before, during, and after implantation. Thus, the design of polymer scaffolds with appropriate biochemistry, mechanical properties, and morphology is a critical step toward developing feasible stem cell therapies for blinding eye diseases. In this work, we aim to design a regenerative scaffold for the retina and determine the interplay among these three key design parameters. First, the feasibility of using a synthetic scaffold to grow and differentiate iPSCs to neural progenitor cells is demonstrated. The porous and degradable poly(lactic-co-glycolic acid) scaffolds employed were able to support a greater density of differentiating iPSCS than traditional tissue culture plastic. Additionally, the power of chitosan, a naturally occurring polymer, to overcome the toxic effects of copper nanoparticles is described. For two different cell types, various doses, and several time points, chitosan coated copper nanoparticles were significantly less toxic than non-coated particles. The mechanical properties of the human retina and the effects of aging and disease were also estimated using measurements of compressive modulus in animal models. In order to reach a range similar to native tissue, polymer mechanical properties were controlled using cross-linking density and surfactant templating. The influence of morphology was studied by inducing polymer structure changes via surfactant templating. Morphology significantly influenced water uptake and compressive modulus for both cross-linked poly(ethylene glycol) (PEG) and cross-linked chitosan hydrogels. Surfactant templating did not negatively affect the biocompatibility of PEG hydrogels and slightly improved the ability of chitosan hydrogels to support the growth and differentiation of iPSCs. Overall we have demonstrated the ability to tune polymer structure, mechanical properties, and biochemistry. These results add to the growing body of research aimed to understand and control cell/material interactions for biomaterial optimization.

Full text
Abstract:
Valles Caldera National Preserve (VCNP) managers were concerned about low elk recruitment observed at the same time as an apparent increase in sightings of coyotes and observations of coyote predation on elk calves. The goal of this study was to describe coyotes’ ecological interactions with elk, particularly coyote diet and movements on the Valle Grande, a large grassland meadow in the southeastern portion of the VCNP. We examined coyote diet by quantifying undigested remains of food items in coyote scats (feces). The most frequent taxa were rodents (montane voles and pocket gophers), elk (adult and calf), insects (grasshoppers and beetles), mountain cottontail rabbits, and plants. Most food types varied significantly seasonally and annually, likely due to climatic variation and the relative availability or vulnerability of food items. In particular, an increase in calf elk consumed during summer 2006 followed a dry winter when elk may have been in a lower nutritional state. We analyzed locations of 33 coyotes, obtained via global positioning system (GPS) collars and radio-tracking. We classified 23 coyotes as residents, living with a social group in a defined area (11.0 km2 mean), and 10 coyotes as transient, with less fidelity to specific areas and often travelling around the edges of the areas occupied by the four resident packs. Coyotes spent most of their time in dry meadow habitat. Coyotes spent more time in riparian habitat than expected based on its availability within home range and less time in forests. We found no relationship between coyote social cohesion (proximity of pack members to each other) and the proportion of elk in coyote diets. We concluded that coyote sociality on VCNP was relatively stable year-round despite changes in biological needs and prey size.
