Resumen

Summary Objective To develop a psychometrically sound self-report questionnaire, the Vocal Fatigue Index (VFI), to help identify individuals with vocal fatigue (VF) and characterize their complaints. Study Design Descriptive research—scale development. Methods Four laryngologists and six speech-language pathologists specialized in voice created a beta version of the VFI (version 1), an index of 21 statements they considered to reflect VF. Two hundred patients presenting to two different clinics completed the VFI-1. Two items from VFI-1 were excluded because of poor item-to-total correlations. The final VFI of 19 items (version 2), completed by 105 patients with voice complaints and 70 vocally healthy individuals, was assessed for its psychometric properties. Results Test-retest reliability for the final VFI was generally strong, as was sensitivity and specificity using the classification table under logistic regression for correctly distinguishing individuals with and without VF. Moreover, factor analysis indicated that VF may be characterized by three factors: (1) factor 1, related to tiredness of voice and voice avoidance, (2) factor 2, related to physical discomfort associated with voicing, and (3) factor 3, related to improvement of symptoms with rest. Conclusion The VFI is a standardized tool that can identify individuals with probable VF with good reliability, validity, sensitivity, and specificity.

Resumen

La inyección de fallos es una técnica utilizada para la validación experimental de Sistemas Tolerantes a Fallos. Se distinguen tres grandes categorías: inyección de fallos física (denominada también physical fault injection o hardware implemented fault injection), inyección de fallos implementada por software (en inglés software implemented fault injection) e inyección de fallos basada en simulación. Una de las que más auge está teniendo últimamente es la inyección de fallos basada en simulación, y en particular la inyección de fallos basada en VHDL. Las razones del uso de este lenguaje se pueden resumir en: " Es un lenguaje estándar ampliamente utilizado en el diseño digital actual. " Permite describir el sistema en distintos niveles de abstracción. " Algunos elementos de su semántica pueden ser utilizados en la inyección de fallos. Para realizar la inyección de fallos basada en VHDL, diferentes autores han propuesto tres tipos de técnicas. La primera está basada en la utilización de los comandos del simulador para modificar los valores de las señales y variables del modelo. La segunda se basa en la modificación del código, insertando perturbadores en el modelo o creando mutantes de componentes ya existentes. La tercera técnica se basa en la ampliación de los tipos del lenguaje y en la modificación de las funciones del simulador VHDL. Actualmente, ha surgido otra tendencia de la inyección de fallos basada en VHDL, denominada genéricamente emulación de fallos. La emulación añade ciertos componentes al modelo (inyectores, que suelen ser perturbadores o mutantes, disparadores de la inyección, recolectores de datos, etc.). El modelo junto con los nuevos componentes son sintetizados en una FPGA, que es donde se realiza la inyección. Con la introducción cada vez mayor de sistemas tolerantes a fallos en aplicaciones críticas, su validación se está convirtiendo en uno de los puntos clave para su uso.

Dentre os assuntos de grande relevância na atualidade, encontra-se a questão da sustentabilidade. Desenvolver e garantir que as futuras gerações também de desenvolvam tem sido um tema bastante debatido nos fóruns nacionais e internacionais. Neste contexto se enquadra também o problema da geração de resíduos, tema que deixa em alerta as empresas e a sociedade, pois trabalhos e pesquisas nesta área apontam crescimento exorbitante na quantidade de resíduos gerados no planeta, e os gestores se deparam com poucas alternativas de destinação para essa gama de material produzido diariamente. Face aos diversos resíduos que são gerados todos os dias, este trabalho aborda especificamente sobre os resíduos de trilho, fruto das manutenções da malha ferroviária do Brasil, buscando estruturar um problema com auxilio da abordagem VFT (Value-focused thinking), do português – Pensamento Focado em Valores. A aplicação estruturada desta abordagem fornece subsídios para criação de novas alternativas de destinação e auxilia na elaboração de um modelo matemático, que consequentemente promove melhorias no processo de apoio a tomada de decisão sobre a recomendação da melhor alternativa. O estudo de caso é desenvolvido na Estrada de Ferro Carajás, principal ferrovia do Brasil no quesito volume de carga transportada, conforme relatório de evolução do transporte ferroviário emitido em agosto de 2016 pela ANTT (Agência Nacional de Transportes Terrestres). Está estrada tem apresentado dificuldades na destinação do grande volume de resíduos de trilhos gerados. O problema apresenta três decisores, para os quais foram traçadas as redes meio-fim e cuja, as preferências se complementam, não sendo identificados conflitos de interesse. O trabalho foi de grande relevância para a empresa, uma vez que foi possível se identificar alternativas até então não aplicadas para a destinação deste resíduo, bem como apontou as similaridades dos pontos de vista dos envolvidos, demostrando o engajamento e nivelamento da liderança quanto à busca de solução do problema e ainda representou a etapa introdutória de um processo que visa aplicação de um método que indique realmente a melhor solução a ser adotada.
Among the issues of great relevance today is the question of sustainability. Developing and ensuring that future generations also have developed has been a hotly debated topic in national and international forums. In this context, there is also the problem of waste generation, a theme that leaves companies and society on the alert, as research and studies in this area point to exorbitant growth in the amount of waste generated on the planet, and managers are faced with few alternatives For this range of material produced daily. Considering the various waste that is generated every day, this work specifically addresses rail waste, the result of maintenance of the Brazilian railway network, seeking to structure a problem with the help of the VFT (Value-focused thinking) approach of Portuguese – Thought Focused on Values. The structured application of this approach provides subsidies for the creation of new allocation alternatives and assists in the elaboration of a mathematical model, which consequently promotes improvements in the process of support decision making on the recommendation of the best alternative. The case study is developed on the Carajás Railroad, the main railroad in Brazil in terms of volume of cargo transported, according to an evolution report on rail transportation issued by ANTT (National Agency for Land Transport) in August 2016. This road has presented difficulties in the destination of the large volume of rail waste generated. The problem presents three decision makers, for whom the half-end networks were drawn and whose preferences complement each other, and conflicts of interest are not identified. The work was of great relevance to the company, since it was possible to identify alternatives hitherto not applied to the destination of this waste, as well as pointed out the similarities of the points of view of those involved, demonstrating the engagement and leveling of the search leadership Of solution of the problem and also represented the introductory stage of a process that aims at applying a method that really indicates the best solution to be adopted.

Resumen

As plantas se defendem do ataque de patógenos através de um sistema imune composto por duas fases. A primeira delas é mediada por receptores localizados na membrana celular ou intracelularmente, os quais são conhecidos como receptores de reconhecimento padrão (do inglês, pattern recognition receptors - PRR). Esses receptores reconhecem moléculas derivadas de microrganismos, as quais são conservadas evolutivamente e são chamadas de padrões moleculares associados a patógenos (do inglês, pathogen-associated molecular patterns - PAMPs). Esse reconhecimento dispara uma resposta de defesa conhecida como PTI (do inglês, PAMP-triggerd immunity - PTI). Alguns patógenos foram aptos a sintetizar moléculas capazes de suprimir a PTI e essas moléculas são denominadas de efetores. A resposta que ocorre devido à ação dos efetores é chamada de susceptibilidade disparada por efetores (do inglês, effector-triggered susceptibility - ETS). Entretanto, plantas resistentes podem reconhecer os efetores através de proteínas de resistência localizadas intracelularmente, ativando a imunidade disparada por efetores (do inglês, effector-triggeredimmunity - ETI). De modo geral, as respostas advindas da PTI e da ETI são similares, mas a segunda é ativada mais rapidamente e é mediada por um único gene de resistência R. Por essa razão, a ETI é conhecida como uma resposta à doença qualitativa e as plantas não desenvolvem sintomas, caracterizando a interação incompatível. Por outro lado, a PTI é mediada por diversos genes e as respostas de defesa são tardias, possibilitando a disseminação do patógeno pelas células da planta e a ocorrência da doença, o que caracteriza a interação compatível. Nas respostas de defesa, moléculas como o óxido nítrico, as poliaminas e o ácido salicílico participam do processo de sinalização. O sistema antioxidante da planta é ativado de modo a mitigar os efeitos das espécies reativas de oxigênio e o metabolismo da planta é alterado. Dessa maneira, o estudo das respostas de defesa contra patógenos, pode ser uma ferramenta útil para estabelecer controles efetivos para as doenças de plantas
Plants defend themselves from pathogen attack through an active immunity system composed by two phases. The first is mediated by cell surface and intracellular pattern recognition receptors (PRR), which recognizes conserved molecules derived from microbes known as pathogen-associated molecular patterns (PAMPs). This recognition triggers a defense response called PAMP-triggered immunity (PTI). Throughout evolution, pathogens were able to synthesize molecules capable of suppressing PTI. These molecules are named effectors and they are responsible for effector-triggered susceptibility (ETS). However, resistant plants can recognize effectors by intracellular resistance (R) proteins, initiating effector-triggered immunity (ETI). In general, responses derived from PTI and ETI are the same, but the latter is activated faster and is mediated by a single R gene. For this reason, ETI-response is also known as qualitative disease response (QDR) and plants do not develop disease symptoms, characterizing the incompatible interaction. On the other hand, PTI is mediated by several genes and the defense response is delayed, enabling the pathogen to spread out and to cause disease. This interaction is known as compatible. In defense responses, molecules like nitric oxide, polyamines and salicylic acid can participate in signaling process. The antioxidant system can be activated to quench the ROS effects and the plant metabolism is altered. In this sense, studying defense responses against pathogens can help to develop tools to establish effective control methods for plant disease

Resumen

Après quelques généralités concernant à la fois les structures à très larges pores et les tamis moléculaires aluminophosphates, une étude des paramètres de cristallisation des produits ayant la topologie VFI est donnée. Une méthode rapide de synthèse pour les produits ayant la topologie de charpente VFI a été développée et est décrite. Cette méthode permet la cristallisation en moins d'une heure d'alumino- et de silicoaluminophosphates purs. Cette méthode demande un accroissement rapide de la température de l'hydrogel. Ces produits sont caractérisés par diffraction des rayons X et par microscopie électronique à balayage. L'incorporation du silicium a été montrée par la RMN 29Si RAM et par microsonde électronique. Le système poreux a été étudié par RMN 129Xe et par adsorption de molécules. La RMN du solide a été largement utilisée pour étudier la structure VFI et son évolution avec la température. Les techniques RMN 27A1 RAM et DOR, 31P RAM et PCRAM, T1 proton ont été utilisées pour cette étude

Resumen

This study is based on the notion that the most widely cited and used instrument for assessing volunteer motivations, the Volunteer Function Inventory (VFI), might not be sufficient in its aspiration to aid, streamline and benefit the recruitment and retention process within volunteer organizations. Understanding volunteers’ motivation is a crucial component in the process of securing future volunteer engagement in a world where their efforts are desperately needed. This study aims to explain motives and motivation behind volunteer efforts in extreme situations as well as to examine the dependability of the theoretical framework in relation to the forthcoming result, based on the following research questions: What motivated Swedish medical personnel to volunteer during the 2014 Ebola outbreak in West Africa? How could the motives and motivation of Swedish medical personnel be categorized in accordance with the Volunteer Function Inventory (VFI)? Is the Volunteer Function Inventory (VFI) a sufficient tool for analyzing the motives and motivation of Swedish medical personnel in the given case? The presented research questions will be answer through a qualitative theory-consuming study, based mainly on interviews. The interviews are, however, complimented by various written sources in the field of research. The result and subsequent analysis confirms the authors’ notion on the VFI and highlights certain deficits in the tool’s execution and its succeeding result. The result of the study shows that the respondents were motivated by a great variety of motivational elements, a variety that the VFI cannot properly account for. Essential information is therefore left unexposed by the VFI, leaving the volunteer organizations in an undesirable situation where they, in their pursuit to recruit and retain the volunteers, are forced to evaluate and accommodate candidates without knowing their complete motivational process. Therefore, the authors deem the tool as applicable but not sufficient. Concludingly, the authors call for additional and more distinct functions in the VFI; an instrument for assessing if the volunteers are intrinsically or extrinsically motivated as well as a sub-section within the tool for determining the presence and character of inhibiting factors affecting the volunteers motivation.

Resumen

Efter nio terminers studier på Malmö högskola så var det tid för det avslutande examensarbetet. Under dessa nio terminer hade vi fått olika upplevelser och erfarenheter av den verksamhetsförlagda tiden berättade för oss av våra medstudenter. Även våra egna erfarenheter varierade. Vi ville därför ta reda på mer om dessa upplevelser och vilka anledningar till variationerna var. Den verksamhetsförlagda tiden uppfattade vi som en stor del av utbildningen för en lärarstudent och den del av utbildningen som förbereder studenten mest för den blivande yrkesrollen. Vi var nyfikna på ifall den verksamhetsförlagda tiden var något som andra lärarstudenter kunde se fram emot och var något som bidrog till deras utveckling som lärare. Studien ansågs vara av allmänt intresse för lärarstudenter som någon gång i framtiden blir handledare och/eller mentorer. Studien ansågs även vara intressant för de ansvariga för den verksamhetsförlagda tiden samt för verksamma handledare och mentorer knutna till Malmö högskola.
The aim of this essay was to examine the student teachers, who study the last semester at Malmö högskola school of education, attitudes towards their trainee post. The attitudes contain not only the trainee post as such, but also attitudes towards the instructor at the trainee post, the mentor at the school of education and the views of the theoretical goals which the student shall achieve. We used a qualitative method in shape of interviews to get the result. The interviews took place at the school of education and were executed at two separate occasions. We did not focus the result on gender, age or ethnicity, our only limitation was that the student’s primary subject was physical education and that they study the last semester at the teacher education. The result showed that the attitudes toward the trainee post were mostly positive. It also showed that the extent of freedom of responsibility was an important aspect of the student’s development and learning and that the theoretical goals were a bit indistinctive. The result was later analysed through two theoretical perspectives, a sociocultural perspective and a theory based on situated learning. This was later connected with a comprehensive discussion.

PROPESQ
Nos últimos 30 anos, os impactos decorrentes da disseminação e utilização da Tecnologia da Informação (TI) puderam ser observados em vários setores da economia, como o industrial e o comercial. Buscando aproveitar os benefícios destes impactos, o uso da TI tem crescido cada vez mais dentro das organizações. Porém, estes benefícios não são facilmente percebidos. Devido a estes fatores, alguns pesquisadores têm estudado e buscado indícios dos retornos alcançados pelas organizações através da utilização da TI. Alguns afirmam que os retornos existem e podem ser percebidos pela organização, outros afirmam que não existem retornos positivos que estejam diretamente relacionados a implementação da TI. A esta aparente inabilidade dos investimentos em tecnologia da informação traduzirem-se em aumento na produtividade, chama-se de Paradoxo da Produtividade. Após o levantamento da literatura e do referencial bibliográfico, foi percebido que os benefícios esperados pela utilização da TI só são alcançados quando a implementação da ferramenta de TI está alinhada com os objetivos, estratégias e cultura da organização. Diante deste cenário, este trabalho tem como objetivo propor e aplicar um modelo para seleção de uma ferramenta de TI que faça uso dos objetivos do decisor para definir critérios e alternativas, buscando assim, estreitar a ferramenta de TI com o alinhamento estratégico. Para tanto, este modelo se baseia em um método de estruturação de problemas e na utilização de uma abordagem multicritério de decisão. Para a estruturação do problema e definição dos objetivos foi utilizado o método VFT (Value Focused Thinking), dele foram extraídos as alternativas e os critérios do problema. O método FITradeoff, que realiza uma avaliação compensatória das alternativas com a vantagem de requerer menos informações por parte do decisor, foi utilizado para a análise das alternativas e apresentação de uma recomendação de ferramenta a ser implementada. A aplicação do modelo proposto foi realizada em uma indústria do ramo alimentício, localizada no interior de Pernambuco, que busca investir em TI para auxiliar ao gestor no alcance dos objetivos da organização. Da aplicação do VFT foram definidas seis alternativas, que foram avaliadas pelo FITradeoff, considerando onze critérios. Conclui-se que, com a utilização do modelo proposto, é possível fazer a seleção de uma ferramenta de TI alinhada com os objetivos estratégicos da organização, desde que haja uma estruturação clara dos objetivos empresariais e da metodologia formal de apoio a decisão. O que possibilita uma maior probabilidade de obtenção de retornos positivos decorrentes da implantação da ferramenta.
In the last 30 years, the impacts of the dissemination and use of Information Technology (IT) have been observed in several sectors of the economy, such as industrial and commercial. Seeking to reap the benefits of these impacts, the use of IT has grown more and more within organizations. However, these benefits are not easily perceived. Because of these factors, some researchers have studied and sought evidence of the returns achieved by the organizations through the use of IT. Some argue that returns exist and can be perceived by the organization, others claim that there are no positive returns that are directly related to the implementation of IT. To this apparent inability of investments in information technology to translate into an increase in productivity, it is called the Productivity Paradox. After the literature and bibliographical references were collected, it was realized that the expected benefits of using IT are only achieved when the implementation of the IT tool is aligned with the organization's objectives, strategies and culture. Given this scenario, this paper aims to propose and apply a model for selecting an IT tool that makes use of the decision maker's objectives to define criteria and alternatives, seeking to narrow the IT tool with strategic alignment. Therefore, this model is based on a problem-structuring method and the use of a multi-criteria approach to decision. For the structuring of the problem and definition of the objectives, the VFT (Value Focused Thinking) method was used, from which the alternatives and the criteria of the problem were extracted. The FITradeoff method, which performs a compensatory evaluation of the alternatives with the advantage of requiring less information from the decision maker, was used to analyze the alternatives and present a tool recommendation to be implemented. The application of the proposed model was carried out in a food industry, located in the interior of Pernambuco, which seeks to invest in IT to assist the manager in achieving the objectives of the organization. From the VFT application, six alternatives were defined, which were evaluated by FITradeoff, considering eleven criteria. It is concluded that, with the use of the proposed model, it is possible to select an IT tool in line with the organization's strategic objectives, as long as there is a clear structuring of the business objectives and the formal decision support methodology. Allows a greater probability of obtaining positive returns due to the implementation of the tool.

Resumen

The aim of this study is to explore what motivates youth from so called “exposed” areas to commit to voluntary work, and how the youth view their own role and the role of the organisation in a context of social mobilization. In order to answer the research questions of this study, the commitment of youth in a non-profit organization has been studied using several different methods of data collection. In order to measure the function of motivation amongst the youth, the survey Volunteer Functions Index (VFI) has been used. VFI is a tool used to measure motivation based on what functions an activity performs in the life of the individual. In order to achieve a greater understanding and be able to explore aspects that the VFI does not cover, four semi-structured interviews were conducted with current and former members of the organization. In order to better understand the context of the organization and to be able to ask more questions during the interviews, a participant observation was done within the work of the organization. The study shows that the youth that participate in the study perceive their commitment in the organization as an important part of their identity and that the identity is an important aspect of what possible actions are perceived to be available and attractive. It also seems as if the commitment to the organization is tied to the opportunity to change the social conditions for one self and others. The study also shows that the organization has been more successful in achieving social mobilization amongst girls than amongst boys, and that some of the participants attribute this to the gender roles that permeate the area
Denna studie syftar till att undersöka vad som motiverar ungdomar från så kallade utsatta områden till att engagera sig ideellt samt hur ungdomarna uppfattar sin egen och organisationens roll i en kontext av social mobilisering. För att kunna besvara studiens frågeställning har ungdomars engagemang i en ideell verksamhet studerats med hjälp av flera olika datainsamlingsmetoder. För att mäta ungdomarnas motivationsgrunder har enkäten Volunteer Functions Index (VFI) använts, ett verktyg som mäter motivation utifrån vilka funktioner aktiviteten har i individens liv. För att skapa en djupare förståelse och kunna fånga upp aspekter som inte täcks in av VFI har fyra semi-strukturerade intervjuer genomförts med nuvarande och före detta deltagare i organisationen. För att skapa förståelse kring kontexten och skapa förutsättningar för att ställa fler frågor under intervjuerna föregicks dessa av en deltagande observation inom organisationens verksamhet. Materialet visar på att ungdomarna som deltar i studien uppfattar engagemanget i organisationen som en viktig del av sin identitet och att identiteten är viktig för vilka handlingsalternativ som man uppfattar som möjliga och attraktiva. Det tycks dessutom som att engagemanget i organisationen är kopplat till möjligheten att förändra de sociala förutsättningarna för sig själva och andra. Studien visar också att organisationen varit mer framgångsrik med social mobilisering bland tjejer än bland killar och att vissa av deltagarna kopplar detta till de könsroller som genomsyrar området.

O projeto de regularização fundiária de um território inicia-se pela delimitação da área, chamada de poligonal. Para traçar uma poligonal, deve-se respeitar os valores e histórias dos habitantes da área. Nesse contexto, as audiências públicas são utilizadas como principal meio de participação da população no projeto, no entanto, estas não geram a percepção esperada, da forma como são tradicionalmente realizadas. Este trabalho apresenta um estudo de caso realizado no sudeste do Pará, sobre a utilização de estruturação de problemas como meio a possibilitar uma participação mais efetiva da população tradicional na concepção do projeto de traçado de sua poligonal. É proposta uma sistemática baseada no VFT (Value Focused Thinking, Keeney (1992)) para clarificar o entendimento dos objetivos da população alvo com o projeto. O VFT se baseia na identificação de objetivos fundamentais e meios e a sua aplicação neste caso mostrou-se adequada, permitindo o envolvimento da população de forma mais ativa, na discussão e compreensão do objetivo de um projeto de traçado poligonal de ocupação, assim como, na elaboração de seu escopo. Com a aplicação dessa sistemática, espera-se reduzir o surgimento de possíveis conflitos das partes interessadas, que em casos extremos podem, inclusive, comportarem-se como bloqueadores à execução do traçado da poligonal, o que em geral, é um comportamento oriundo do sentimento de insatisfação com o serviço prestado.
The project of land regularization of a territory begins by delimiting the area, called a polygon. To draw a traverse, one must respect the values and stories of the inhabitants of the area. In this context, public hearings are used as the main means of participation of the population in the project, however, these do not generate the expected perception, in the way they are traditionally carried out. This paper presents a case study carried out in the southeast of Pará, on the use of problem structuring as a means to enable a more effective participation of the traditional population in the design of the tracing project of its traverse. A system based on VFT (Value Focused Thinking, Keeney (1992)) is proposed to clarify the understanding of the objectives of the target population with the project. The VFT is based on the identification of fundamental objectives and means and its application in this case proved to be adequate, allowing more active involvement of the population in the discussion and understanding of the objective of a polygonal occupation tracing project, in the elaboration of its scope. With the application of this systematics, it is hoped to reduce the appearance of possible conflicts of the interested parties, which in extreme cases may even behave like blockers to the execution of the tracing of the traverse, which in general, is a behavior originating from the feeling Dissatisfaction with the service provided.

Resumen

Denna studie är ett försök att utforska lärarstudenters upplevelser av sin verksamhetsförlagda utbildning. Med hjälp av en intervjuguide kopplade till gällande styrdokument, utvärderingar och tidigare forskning genomfördes tio intervjuer som tydliggjorde flera aspekter som är av antingen positiv eller negativ karaktär för studentens upplevelser av VFU:n.

Det som upplevs som positivt av studenterna är att VFU-skolan ger dem en introduktion, att det finns tillgång till en egen arbetsplats, att det finns tid för reflektion, att personalen på skolan har en positiv inställning till dem som studenter, att man blir inkluderad i arbetslaget och att handledaren visar engagemang och ger studenten frihet i undervisningssituationen.

De negativa upplevelser studenterna framförde gällde kommunikationen och samarbetet mellan högskola och VFU-skola samt bedömningen av VFU:n.

Resumen

Syftet med vår undersökning var att synliggöra studenternas upplevelse av handledningen under den verksamhetsförlagda tiden i utbildningen. Vi problematiserade hur handledningen leder till en progression som möjliggör att studenterna kan uppnå lärandemålen under sin praktik. Detta gjorde vi genom att studera handledarteorier samt Malmö högskolas syfte med den verksamhetsförlagda tiden. Vi använde oss av en webbaserad enkätundersökning för informationsinsamlingen och analyserade resultatet efter de valda teorierna. I resultatet uppgav de tillfrågade studenterna en positiv bild av sin progression men vi anser i vår slutsats att handledningen till stor del inte getts på ett sätt som är förenligt med styrdokument och de handledningsteorier vi studerat.

Resumen

Lorentz TEM observations of magnetic nanoparticles contain information on the magnetic and electrostatic potentials of the sample. These potentials can be extracted from the electron wave phase shift by separating electrostatic and magnetic phase shifts, followed by 3D tomographic reconstructions. In past, Vector Field Electron Tomography (VFET) was utilized to perform the reconstruction. However, VFET is based on a conventional tomography method called filtered back-projection (FBP). Consequently, the VFET approach tends to produce inconsistencies that are prominent along the edges of the sample. We propose a model-based iterative reconstruction (MBIR) approach to improve the reconstruction of magnetic vector potential, A(r). In the case of scalar tomography, the MBIR method is known to yield better reconstructions than the conventional FBP approach, due to the fact that MBIR can incorporate prior knowledge about the system to be reconstructed. For the same reason, we seek to use the MBIR approach to optimize vector field tomographic reconstructions via incorporation of prior knowledge. We combine a forward model for image formation in TEM experiments with a prior model to formulate the tomographic problem as a maximum a posteriori probability estimation problem (MAP). The MAP cost function is minimized iteratively to deduce the vector potential. A detailed study of reconstructions from simulated as well as experimental data sets is provided to establish the superiority of the MBIR approach over the VFET approach.

Resumen

With extensive use of information systems in day-to-day business operations, many organizations are facing challenges to develop robust computer-based information systems that are secure and widely used by the user community. In order to develop information systems that are secure and useful, understanding what stakeholders consider important and value about the security and usability is critical. Security refers to confidentiality, integrity and availability and usability refers to efficiency, effectiveness and user satisfaction. Using Value Focused Thinking approach, this research first proposes the usability objectives based on the values of system developers and users. Using the security objectives proposed by Dhillon & Torkzadeh (2006) and the usability objectives, this research proposes hierarchies with the overall/over-arching goals of security (confidentiality, integrity, availability) and/or usability (efficiency, effectiveness and satisfaction). This research also analyzes a case of computer hacking and identifies which of the security and usability objectives that have not been met in that case study. The research contributions which include the usability objectives and security and usability hierarchies can be useful for theoretical as well as practical purposes.

Resumen

Velofarynxinsufficiens (VFI) innebär en nedsatt förmåga att under tal och födointag stänga till mellan mun- och näshåla vilket leder till ett avvikande tal. Operation med svalglambå är en metod som kan användas för att behandla VFI och tidigare forskning har visat goda resultat avseende dess effekt på talet. Dock menar vissa forskare att operationen kan ha negativa effekter och att den bakomliggande orsaken till insufficiensen kan påverka graden av framgång. Aktuell studie ämnade undersöka huruvida operation med svalglambå påverkade talet vid VFI samt belysa om några skillnader fanns mellan olika patientgrupper avseende operationens effekt på tal. De olika patientgrupperna var (a) patienter med spalt, (b) patienter med spalt i kombination med ett syndrom eller en sekvens och (c) patienter med VFI utan förekomst av spalt. Eftersom tidigare studier dessutom indikerat att postoperativ talbehandling hos logoped kan vara relevant för vissa patienter undersöktes det också under vilka omständigheter det skedde. Journaler, inklusive perceptuella lyssnarbedömningar av talet genomförda av logopeder, och enkätsvar studerades för de 66 patienter som deltog. Dessa utgjorde 43,1% av alla 153 patienter som genomgått operation med svalglambå på Akademiska sjukhuset i Uppsala år 2000-2011. Talbedömningar genomförda före och ett år efter operation visade att talet förbättrades avseende förståelighet (p<0,001), hypernasalitet (p=0,005) och tryckreducerad artikulation (p=0,001) samtidigt som hyponasalitet inte ökade (p=0,55). Patienter med spalt i kombination med syndrom eller sekvens uppvisade större förbättring av hypernasalitet jämfört med de andra grupperna (p=0,037). 32 patienter gick i postoperativ talbehandling hos logoped och patienter med enbart spalt fick behandling i något högre utsträckning än patienter med gomspalt i kombination med syndrom eller sekvens. Kompensatorisk artikulation var den enda talavvikelsen vars förekomst kunde relateras till att patienten gick i postoperativ talbehandling. Resultaten indikerar att operation med svalglambå är en lämplig metod för att behandla VFI oavsett bakomliggande orsak. Nyckelord: Velofarynxinsufficiens, svalglambå, LKG, syndrom, primär VFI, talavvikelse, talbehandling
Velopharyngeal insufficiency (VPI) refers to the failure of separating the oral cavity from the nasal cavity during speech and deglutination. This leads to increased airflow through the nose and is the cause of resonance disturbances such as hypernasality and nasal emission. Previous studies evaluating the success of pharyngeal flap surgery to treat VPI have indicated satisfying result although some studies stress side effects due to postoperative constrictions. The underlying cause of VPI has been shown to influence the postoperative result. With this background we investigated the differences in speech, pre-, and one year post pharyngeal flap surgery and compared the three groups (a) cleft palate, (b) cleft palate in combination with a syndrome or a sequence, and (c) VPI without cleft palate. We also investigated the co-occurance of postoperative speech therapy regarding different speech parameters and the underlying cause of VPI. 66 of the 153 patients who underwent a pharyngeal flap surgery at Akademiska sjukhuset in Uppsala 2000-2011 agreed to participate in the study. 32 patients attended postoperative speech therapy. The data was collected through medical records and a survey and included perceptual analyses of speech pre-, and post surgery performed by speech and language pathologists. According to the results from the perceptual assessment, the pharyngeal flap surgery resulted in improved speech; intelligibility (p<0.001), hypernasality (p=0.005) and weak consonant pressure (p=0.001). Hyponasality did not increase significantly (p=0.55). Patients with cleft palate in combination with a syndrome or a sequence showed greater improvement regarding hypernasality (p=0.037). The only speech disturbance co-occurring with the presence of postoperative speech therapy was compensatory articulation. Patients with cleft palate seemed to receive postoperative speech therapy in a higher extent than patients with cleft palate in combination with a syndrome or a sequence. These results indicate that pharyngeal flap surgery is a successful way of treating VPI disregarding underlying cause. Keywords: Velopharyngeal insufficiency, pharyngeal flap, cleft palate, syndrome, primary VPI, speech deviation, speech therapy

Resumen

Doutoramento em Gestão
Com a multiplicação de dispositivos tecnológicos e com as suas complexas interacções, os ciber riscos não param de crescer. As entidades supervisoras estabelecem novos requisitos para forçar organizações a gerir os ciber riscos. Mesmo com estas crescentes ameaças e requisitos, decisões para a mitigação de ciber riscos continuam a não ser bem aceites pelas partes interessadas e os benefícios dos investimentos em segurança permanecem imperceptíveis para a gestão de topo. Esta investigação analisa o ciclo de vida da gestão de ciber risco identificando objectivos de mitigação de ciber risco, capturados de especialistas da área, prioritizando esses objectivos para criar um modelo de decisão para auxiliar gestores de risco tendo em conta vários cenários reais, desenvolvendo um conjunto de princípios de gestão de risco que possibilitam o estabelecimento de uma base para a estratégia de ciber risco aplicável e adaptável às organizações e finalmente a avaliação dos benefícios dos investimentos em segurança para mitigação dos ciber riscos seguindo uma abordagem de melhoria contínua. Duas frameworks teóricas são integradas para endereçar o ciclo de vida completo da gestão de ciber risco: o pensamento focado em valor guia o processo de decisão e a gestão de benefícios assegura que os benefícios para o negócio são realizados durante a implementação do projecto, depois de tomada a decisão para investir numa solução de segurança para mitigação do ciber risco.
With the multiplication of technological devices and their multiple complex interactions, the cyber risks keep increasing. Supervision entities establish new compliance requirements to force organizations to manage cyber risks. Despite these growing threats and requirements, decisions in cyber risk minimization continue not to be accepted by stakeholders and the business benefits of security investments remain unnoticed to top management. This research analyzes the cyber risk management lifecycle by identifying cyber risk mitigation objectives captured from subject matter experts, prioritizing those objectives in a cyber risk management decision model to help risk managers in the decision process by taking into account multiple real scenarios, developing the baseline of cyber risk management principles to form a cyber risk strategy applicable and adaptable to current organizations and finally evaluating the business benefits of security investments to mitigate cyber risks in a continuous improvement approach. Two theoretical frameworks are combined to address the full cyber risk management lifecycle: value focused thinking guides the decision process and benefits management ensures that business benefits are realized during project implementation, after the decision is taken to invest in a security solution to mitigate cyber risk.

Resumen

In the last decade, a considerable growth has been added to the volume of the credit risk derivatives market. This growth has been followed by the current financial market turbulence. These two periods have outlined how significant and important are the credit derivatives market and its products. Modelling-wise, this growth has parallelised by more complicated and assembled credit derivatives products such as mth to default Credit Default Swaps (CDS), m out of n (CDS) and collateralised debt obligation (CDO). In this thesis, the Lévy process has been proposed to generalise and overcome the Credit Risk derivatives standard pricing model's limitations, i.e. Gaussian Factor Copula Model. One of the most important drawbacks is that it has a lack of tail dependence or, in other words, it needs more skewed correlation. However, by the Lévy Factor Copula Model, the microscopic approach of exploring this factor copula models has been developed and standardised to incorporate an endless number of distribution alternatives those admits the Lévy process. Since the Lévy process could include a variety of processes structural assumptions from pure jumps to continuous stochastic, then those distributions who admit this process could represent asymmetry and fat tails as they could characterise symmetry and normal tails. As a consequence they could capture both high and low events¿ probabilities. Subsequently, other techniques those could enhance the skewness of its correlation and be incorporated within the Lévy Factor Copula Model has been proposed, i.e. the 'Stochastic Correlated Lévy Factor Copula Model' and 'Lévy Random Factor Loading Copula Model'. Then the Lévy process has been applied through a number of proposed Pricing Basket CDS&CDO by Lévy Factor Copula and its skewed versions and evaluated by V-FFT limiting and mixture cases of the Lévy Skew Alpha-Stable distribution and Generalized Hyperbolic distribution. Numerically, the characteristic functions of the mth to default CDS's and (n/m) th to default CDS's number of defaults, the CDO's cumulative loss, and loss given default are evaluated by semi-explicit techniques, i.e. via the DFT's Fast form (FFT) and the proposed Very Fast form (VFFT). This technique through its fast and very fast forms reduce the computational complexity from O(N2) to, respectively, O(N log2 N ) and O(N ).

Resumen

Existuje veľa rôznych dôvodov pre spoločnosti a organizácie, prečo by mali investovať do virtualizácie. Asi najväčší dôvod je finančná motivácia, pretože nasadenie virtualizácie môže ušetriť nemálo peňazí. Táto práca sa zaoberá práve problémom virtualizácie I/O operácií v sieťovom prostredí. Cieľom práce je tvorba softvérových ovládačov pre I/O virtualizáciu, ktoré by mohli pracovať s hardvérovo akcelerovanými sieťovými kartami. Hlavným prínosom ovládačov by mala byť použiteľnosť a čo najmenšia strata prenosového výkonu vo virtualizovanom prostredí. Pred popisom finálnych detailov ovládačov je však potrebné uviesť potrebné teoretické základy. Teoretická časť sa zaoberá súčasnými trendami vo virtualizácii I/O, technológiami ako sú virtio, vhost, SR-IOV, VFIO a mdev. V praktickej časti sú navrhuté dva spôsoby riešenia problému. Prvým je použitie technológie virtio (emulácia softvéru). Druhé je založené na technológii VFIO-mdev (hybridná paravirtualizácia). Pokiaľ sa jedná o výkon a konfigurovateľnosť zariadení, oba prístupy majú rôzne benefity. Tieto riešenia majú aj svoje nevýhody, ako je zložitosť riešenia a náročnosť integrácie do systému. Požadované ciele boli úspešne dosiahnuté vo forme prototypu ovládača nfb_mdev.

Thin-Film Accumulation Type Vacuum Freezing Ice Production (VFIP) Method S. F. ChouH. I. Lin Abstract A thin film accumulation type vacuum freezing ice production (VFIP) system based on the solid-liquid-vapor multiple phase transformation and the latent-heat coupling mechanism is introduced in this work. Theoretical model of VFIP system has been established first. Coupled heat and mass flux equations based on the irreversible thermodynamics have been applied to depict the ice growth phenomenon under vacuum condition, and equations for the ice growth rate and heat transfer have been derived. Experiments to demonstrate the VFIP process were then performed. The experimental results agree well with the theoretical analysis. Ice growth rates of the VFIP system have been found at least one order of magnitude higher than the growth rates of the conventional freezing process, which produces ice under the atmospheric pressure. The correlation of heat transfer coefficient and the correction factor of the phenomenological coefficient of the VFIP system are established attributing to the experimental results. The modified ice growth rate equation is introduced to match the actual freezing process. The salient outcomes of the present study could be revolutionary to the commercial ice production applications. With a unique feature of spontaneous temperature gradient developed inside the ice layer, the extremely fast and energy-saving ice-block production features the VFIP method could totally overcome the disadvantages in energy consumption and ice growth rate of the current vapor-compression methods.

Nowadays, embedded systems play an important role in the new living fashion. Embedded systems in addition to have light weight and small features, their versatile characteristics attract lots of concerns about component-based design. These concerns are primarily about component interface design, component reusability and component replacement functionality. Besides, many of them need storage capability to offer advanced application features. Therefore, file system occupies an important position in embedded systems. It influences files access efficiency and storage management. This thesis describes a component-based VFAT file system design and implementation method. In this research, to provide the basic functionality of VFAT file system, we borrowed some codes from Linux 2.0.33 kernel VFAT file system to support the basic VFAT operations. We then implemented it as a component-based file system, and integrated it to a component-based operating system - LyraOS. Beside, some modifications are added to make it more adaptable and in some aspects to improve file system performance. The major works include: (1) modeling VFAT file system to be a separate and self-contained C++ component, (2) modifying Linux VFAT source code to make it be able to operate efficiently in a resource limited embedded system, (3) integrating it with other kernel components of LyraOS, (4) supporting disk-based and RAM-based storage device, and (5) providing the compatible POSIX file system interface. Performance evaluation under modified Andrew and LFS file system benchmarks show that LyraOS component-based VFAT file system (LyraFILE) operates at low cost. The experience of this study can be of practical value to serve as the reference for embedding Linux file system into a target system that needs storage capability.

Pseudomonas syringae, a Gram-negative rod-shaped bacterium, can infect a wide array of host plants and cause different disease symptoms. Due to its broad host range and economical importance, P. syringae has become one of the most studied model organisms. After P. syringae enters plants, various effector proteins can be delivered into host cells via type III secretion system, which can then interfere with normal physiological state or inhibit basal defense responses of plants, leading to colonization and growth of the pathogens, and later, disease symptoms on host plants. However, plants have evolved some resistance genes that can recognize these effectors to activate specific host resistance in order to block the bacterial growth. AvrPtoB, a well-known type III effector of P. syringae pv. tomato, is recognized by a resistance protein Pto to activate downstream signal transduction for resistance responses. Like AvrPtoB, a homolog of avrPtoB from a bean pathogen P. syringae pv. syringae B728a(AvrPtoBB728a), can trigger Pto-mediated resistance, but can also induce resistance on cultivate tomato lacking Pto. Previous studies have proved that this resistance is conferred by Pto family members and Prf. Thus, the purpose of this study was to identify plant genes responsible for this host resistance, and domains in AvrPtoBB728a required for this host resistance. Using a yeast two-hybrid system combined with the pathogenicity assay, we successfully identified that SlPtoB was responsible for tomato resistance and found out the smallest region of AvrPtoBB728a required for recognition is amino acids 91-330. These results proved that Pto paralogs in Pto locus do have resistance function, not simply a phenomenon of gene duplication. AvrPtoBB728a shares high sequence similarity with AvrPtoB, but they have quite different functions. This may imply that they activate tomato resistance mechanisms via different pathways. In the future, features of AvrPtoB can be focused for investigation of the reason why AvrPtoBB728a functions differently from AvrPtoB.

Resumen

Angsterkrankungen stellen einen großen Anteil an psychischen Erkrankungen dar und gehen zum Teil mit großem Leidensdruck einher. Da die leitliniengerechte Therapie mit hohen Rückfallraten und ca. 25% Nonrespondern einhergeht, stellt sich die Frage nach alternativen Behandlungsmethoden. Transkranielle Magnetstimulation findet als nichtinvasive Behanslungsmethode zunehmend Anwendung bei neurologischen und psychiatrischen Erkrankungen. In der vorliegenden randomisierten, kontrollierten Studie wurde die Wirkung der TMS auf den frontotemporalen (FTC) und dorsolateralen präfrontalen Cortex (dlPFC) untersucht. Dazu wurden 42 gesunde Probanden zwischen 18 und 59 Jahren zur Hälfte TMS-stimuliert, die andere Hälfte wurde scheinstimuliert. Vor und nach Stimulation bzw. Placebostimulation wurde die Aktivität von FTC und dlPFC mit Nah-Infrarotspektroskopie (NIRS) während der Durchführung des Verbal Fluency Tasks (VFT) gemessen. In dieser Studie konnte keine Veränderung der hämodynamischen Gehirnaktivität durch TMS nachgewiesen werden, jedoch äußerten die Probanden der Stimulationsgruppe im Gegensatz zu den Probanden der Placebogruppe, Nebenwirkungen wie Schmerzen oder Muskelzucken verspürt zu haben. Die während des VFT laufende NIRS zeigte eine signifikant höhere Durchblutung und damit Aktivierung des linken FTC im Seitenvergleich und eine signifikant höhere Aktivierung während der semantischen als bei der phonemischen VFT-Bedingung, analog zu früheren, vergleichbaren Untersuchungen. Die Frage, ob sich TMS als mögliche Behandlungsmethode bei Angsterkrankungen eignet, lässt sich anhand der hier vorliegenden Studie nicht abschließend beantworten
Anxiety disorders constitute a large proportion of mental illnesses and are often accompanied by great strain imposed by suffering. Since guideline-based therapy is characterised by high relapse rates and about 25% of non-responders, the question of alternative treatment methods arises. Transcranial magnetic stimulation as a non-invasive treatment method is being increasingly applied to treat neurological and psychiatric diseases. In the presented randomised, controlled study, the effect of TMS on the frontotemporal (FTC) and dorsolateral prefrontal cortex (dlPFC) was examined. For this purpose, one half of 42 healthy volunteers between 18 and 59 years of age received TMS stimulation while the other half received sham stimulation. Before and after both real and placebo stimulation, the activity of FTC and dlPFC was measured with near-infrared spectroscopy (NIRS) during the execution of Verbal Fluency Tasks (VFT). In this study, no change in hemodynamic brain activity through TMS could be detected. However, contrary to the placebo group volunteers, the stimulation group volunteers reported side effects such as pain or muscle twitching. The NIRS running during VFT showed a significantly increased blood flow and thus an activation of the left FTC in the side comparison, as well as a significantly enhanced activation during the semantic VFT condition in comparison with the phonemic one, analogous to previous comparable examinations. The question of whether TMS presents itself as a potential treatment for anxiety disorders can not be conclusively answered on the basis of the study presented here

This century would be characterized by the competition among the application of information and network in the advent of the new economy under the Internet. Under this new economy, Network and Information Science is getting and getting development, traditions economy would make a hung change. Enterprises would pay attention to all kinds of changes, and result to regulate business nature and operate a business. By this way , enterprises would be eliminated through competition. Recent year, Enterprises would confront with crisis in Taiwan, because operating cost is getting and getting to grow. Most of manufacturing industries left gradually to develop in China or Southeast Asia . Global operating style would make to reduce time that came back information, customers asked to tend to variety. Enterprises must provide the most fast and satisfied service to customers under finite resources. Enterprises made to achieve the goal ,they would be served as the framework of analysis for the operations of virtual factories. The main objective of this study is to analyze the operation model of virtual factories, and to evaluate the Supply Chain Management that affect the development of the operation model of virtual factories in electrical technology industry. This study would propose some conclusions about the development of virtual operation models for the other industries.

A presente investigação tem por objetivo estudar os fatores motivacionais dos voluntários das equipas de rua de uma IPSS de Lisboa - Comunidade Vida e Paz e a relação com a sua satisfação de vida. Foram recolhidas respostas de 44 homens (38,6 %) e 70 mulheres (61,4 %), o que perfaz uma amostra de 114 voluntários (N=114), com idades compreendidas entre os 19 e os 64 anos, sendo os níveis etários mais significativos os que se situam entre os 35-44 anos (N=28 24,5%). As medidas utilizadas foram o Inventário das Funções do Voluntário (VFI), instrumento desenvolvido por Gil Clary, Mark Snyder, Robert Ridge, John Copeland, Arthur Stukas, Julie Hangen e Peter Mien (1992), que mede seis fatores motivacionais para exercer o voluntariado e a Escala de Satisfação com a Vida, versão de Diener, RA.,Emmons, R.J.,Larsen, & S. Griffin (1985), com a tradução de J. Rosa e A. Baptista,1997, e que avalia o juízo subjetivo que cada indivíduo faz sobre a qualidade da sua própria vida. A análise dos dados permitiu concluir que, à semelhança dos vários estudos, este vai ao encontro da literatura e os resultados obtidos convergem maioritariamente quanto à ordenação dos fatores motivacionais dos voluntários. Já nas hipóteses levantadas, concluiu-se que não existem diferenças estatisticamente significativas entre as dimensões do estudo. Os valores, género Masculino -25,250 M (Média) e 7,386 DP (Desvio Padrão) e género Feminino - 28,914 M e 4,667 DP atingidos na função Experiência são a exceção e revelam as diferenças entre os sexos, onde os sujeitos do sexo feminino apresentam níveis significativamente superiores ao masculino.

Resumen

Service-learning is an organized volunteer activity in which learners serve the community while utilizing and enhancing their own skills, thus benefiting both the learners and the community. Studies have shown that students gain various benefits from participating in a service-learning activity, especially in their academic skills and civic growth through continued reflections (Eyler, Giles, & Braxton, 1997; Eyler & Giles, 1999; Billig, 2000; Grassi et al., 2004; Steinberg, Bringle, & Williams, 2010), often increasing their motivation to learn the related subject (Steinberg et al., 2010). Service-learning has been implemented in foreign language courses in the United States, especially Spanish (Barreneche & Ramos-Flores, 2013). However, service-learning literature on Japanese as a foreign language is limited.

The researcher founded a service-learning program in the Japanese language. In the program, the university students enrolled in intermediate- or higher-level Japanese courses help Japanese children with their schoolwork as volunteer tutors. The researcher conducted a qualitative case study on four of the student-tutors to examine the program's potential benefits to maintain and enhance the student-tutors' various motivations toward learning Japanese. The Volunteer Functions Inventory (VFI) (Clary, Snyder, & Ridge, 1998) was used as an analysis scheme, which reports six most commonly found functions, or varying motivations, for participating in a volunteer activity. The student-tutors indicated five out of the six VFI functions, showing a connection between their service-learning experience and their personal growth. They built strong connections with the Japanese community and kept their motivation to improve their Japanese skills to better help the children. It is hoped that the present research will contribute to providing an example of Japanese service-learning in the U.S.
