Os aceleradores de feixes de elétrons são utiizados em muitas aplicações, tais como pesquisa em física básica, química, medicina, biologia molecular, microeletrônica, agricultura e indústria, dentre outras. Na maioria dos aceleradores, por meio de aquecimento do filamento de tungstênio e da alta tensão via gerador Cockcroft-Walton, os elétrons passam por um campo elétrico na câmara em vácuo e são acelerados de acordo com a alta tensão aplicada, transferindo energia aos elétrons. Para fins industriais, um dos equipamentos mais utilizados é o Acelerador Industrial de Elétrons Dynamitron®. No IPEN-CNEN/ SP, instalou-se um acelerador de feixe de elétrons Dynamitron®, fabricado pela RDI Radiation Dynamics Inc., modelo DC1500/25/4, em 1978. A tecnologia analógica aplicada nesse acelerador industrial de elétrons data de 1960 e 1970. Assim, além da tecnologia de controle operacional obsoleta, não há mais peças e componentes sobressalentes originais, fornecidos pelo fabricante (RDI) ao equipamento. O objetivo deste trabalho foi desenvolvido um sistema automatizado para controle operacional do acelerador industrial de elétrons Cockcroft-Walton de 37,5 kW (1,5 MeV e 25 mA) no Instituto. / Electron beam accelerators are used in many applications, such as basic research in physics, chemistry, medicine, molecular biology, microelectronics, agriculture and industry, among others. In most accelerators, by means of heating a tungsten filament and high-voltage from a CockcroftWalton generators, the electrons go through an electrical field in the vacuum chamber and are accelerated according to the high-voltage applied to transferring energy to the electrons. For industrial purposes, one of the most used of equipment is the Dynamitron® Industrial Electron Beam Accelerator. In IPEN-CNEN/SP, this Dynamitron® Accelerator, manufactured by RDI - Radiation Dynamics Inc, model DC1500/25/4, was installed, in 1978. The analogical technology applied in this industrial accelerator dates from 1960 and 1970. Therefore, besides the obsolete operational control technology, there are not spare parts or components supplied by the manufacturer (RDI).The goal of this work was to develop an automated system for the operational control of the Cockroft-Walton industrial electrons accelerator of 37.5 kW (1.5 MeV and 25 mA), at IPEN-CNEN/SP.

There is evidence that the way individuals perceive their life at work (satisfaction / dissatisfaction) can affect both their labor performance and their physical and mental health. According to Signorini (2000), although there are doubts as to the exact meaning of the term quality of life at work, the basic elements that distinguish them would be the concern with the effect of work on people and on the organizational effectiveness, as well as on the idea of participation in problem solving and organizational decision making. This dissertation is initially structured on a theoretical discussion about QLW and related topics, followed by methodological procedures adopted, results obtained and closing remarks. Although the research is classified as qualitative, quantitative data have been used in order to strengthen the results obtained. The survey instrument used was based on the structured Model of Walton, contemplating the categories of the Likert scale applied to police officers who work at the 1st and 5th Police Stations, which include the city of João Pessoa. It was found that in their perception, they are not satisfied with their quality of work life at work in all its aspects (dimensions), since the mean scores obtained in the Likert scale did not even exceed the value 4. Comparing the mean scores of the dimensions that make up the instrument of quality of work life with a cutout per battalion, we have that the mean scores generated by the officers of the 1st Battalion were always higher than the mean scores produced by the officers of the 5th Battalion. It was found also that the police officers who act as prison guards / custody of hospitals are those with poorer perceived quality of life at work. / Há evidências de que a forma como o indivíduo percebe sua vida no trabalho (satisfação/insatisfação) pode afetar tanto o seu desempenho laboral quanto sua saúde física e mental. De acordo com Signorini (2000), embora existam dúvidas quanto ao exato significado do termo qualidade de vida no trabalho, os elementos básicos que as distinguem seriam a preocupação com o efeito do trabalho nas pessoas e na eficácia da organização e, na ideia da participação dos trabalhadores na solução de problemas e no processo decisório organizacional. O objetivo dessa dissertação foi analisar a qualidade de vida no trabalho dos policiais militares que atuam no município de João Pessoa Paraíba. Inicialmente está estruturada em uma discussão teórica a cerca da QVT e assuntos afins, seguida dos procedimentos metodológicos adotados e os resultados que a pesquisa permitiu descobrir, e por fim as considerações finais. O instrumento de pesquisa utilizado foi baseado no Modelo de Walton, estruturado contemplando as categorias da escala de Likert, aplicado aos policiais militares, do 1º Batalhão e 5º Batalhão, que contemplam a cidade de João Pessoa. Constatou-se, que na percepção dos PM s da cidade de João Pessoa, não estão satisfeitos com a sua qualidade de vida no trabalho, em todos os seus aspectos (dimensões), haja vista que os escores médios obtidos sequer ultrapassaram o valor 4. Comparando os escores médios, das dimensões que compõem o instrumento de qualidade de vida no trabalho com um recorte por batalhão, tem-se que os escores médios gerados pelos policiais do 1º Batalhão foram sempre maiores que os escores médios produzidos pelos policiais do 5º Batalhão. Detectou-se, também, que os policiais que atuam como guarda de presídio/custódia de hospitais são os que apresentam uma pior percepção de qualidade de vida no trabalho.

This thesis argues that photographs enhance the repertoire of seeing the way eyeglasses, microscopes and telescopes do. This kinship is based on these devices sharing a feature called transparency. Transparent devices facilitate visual information about objects without interrupting the causal link between the object and our eyes, and do so by maintaining a belief independent and similarity preserving counterfactual dependence on that object. Handmade pictures also offer visual information about objects, but because handmade pictures depend on the perceptual experiences of their makers, they interrupt the causal link between the object represented and our eyes. Consider how a drawing can represent the misperceptions and hallucinations of its illustrator, but in contrast, photographs do not reproduce the contents of hallucinations or misperceptions had by their photographers. I use transparency to map the epistemic province of photographs, arguing that photographs are not just ontologically similar to microscopes and telescopes, but also epistemically akin to them, –perhaps even more than they are like other picture types. This is illustrated by two further comparisons. The first is technological: while cameras define the information scope of photographs, handmade pictures are not subject to pre-sets that strictly limit their representational scope in the same way. The second comparison shows how photographs and handmade pictures are subject to different sceptical hypotheses: handmade pictures are susceptible to scepticism about their illustrator, –i.e., as we might question the credibility of someone giving testimony– but photographs are not beholden to scepticism about their photographer. I conclude with a proposal on the epistemology of photography, where contrary to the character of other picture types, photographs provide genuine perceptual knowledge about objects.

Notre recherche en didactique des sciences, explore la potentialité des objets scientifiques contemporains à devenir des objets de patrimoine à travers un cas d'étude : l'accélérateur de particules Cockcroft-Walton (CW). Nous faisons l'hypothèse que la valorisation des objets scientifiques contemporains, étape importante du processus de patrimonialisation, est spécifique et nécessite une expertise particulière. Notre travail a été réalisé grâce au dispositif CIFRE, nous permettant de travailler aux côtés du musée des Confluences à Lyon, qui expose un accélérateur de particules CW dans Sociétés : le théâtre des hommes. L'Institut de Physique Nucléaire de Lyon (IPNL) possède également un appareil de ce type, qui est aujourd'hui au cœur d'un projet de valorisation. Notre analyse s'appuie sur une étude du contexte, historique, épistémologique et social, de « naissance » du premier accélérateur CW et d'une étude scientifique de l'objet. Nous avons également mené deux enquêtes, la première visant à retracer la trajectoire de l'accélérateur CW à Lyon, la seconde à retrouver l'ensemble des accélérateurs CW dans le monde. En nous appuyant sur différents travaux qui ont souligné les étapes du processus de patrimonialisation, nous avons caractérisé les spécificités du patrimoine scientifique contemporain, et recherché les traces laissées par ces caractéristiques dans la mise en exposition de l'objet. Nos résultats mettent en évidence le manque d'informations permettant l'interprétation et l'appropriation de l'accélérateur CW par un public, et nous invitent à interroger le contenu représentationnel de l'objet, véhiculé à travers d'autres contextes d'utilisation, formel ou fictionnel / Our thesis in science education explore the potentiality of contemporary scientific objects to become objects of heritage through a study case: the Cockcroft-Walton particle accelerator (CW). We call it “patrimonialisation” (the making of heritage) according to Information and Communication Sciences. We assume that the value of contemporary scientific objects, an important stage of the patrimonialisation, is specific and requires a particular expertise. Our work was realized thanks to a french financing facility, allowing us to work with Le musée des Confluences in Lyon (France), which exposes a particle accelerator CW in Societies: the human theater. The Institute of Lyon Nuclear physics (IPNL) also possesses a device of this type, who is the focus of a recognition project. sing a multidisciplinary approach, our analysis begin with a study of historical, epistemological, social and scientific context, of the first one CW. We also led two inquiries, the first one to redraw the accelerator CW trajectory in Lyon, the second to find all the accelerators CW in the world. Several studies have indeed highlighted the stages of the patrimonialisation. Relying on these studies we characterized the specificities of the contemporary scientific heritage, and looked for tracks left by these characteristics in the exhibition text (museography). Our results demonstrate the lack of information allowing the interpretation (lecture) and the appropriation of the accelerator CW by a public, and invite us to question the representational contents of the object, conveyed through other contexts of use, formal or fictional

O trabalho ocupa papel central na vida do homem, podendo ser fonte de sofrimento ao trabalhador, acarretando, em alguns casos, doenças físicas e psíquicas. A QVT pode contribuir para tornar o ambiente de trabalho mais saudável ao trabalhador, proporcionando maior bem-estar e satisfação. Este trabalho tem como objetivo investigar a percepção dos servidores acerca da Qualidade de Vida no Trabalho na Reitoria do IFSULDEMINAS. Para atingir este objetivo o trabalho foi dividido em oito partes: a introdução; considerações sobre o trabalho; um capítulo destinado à Qualidade de Vida no Trabalho; os modelos de análise de QVT; os procedimentos metodológicos; análise de dados; considerações finais e proposta de intervenção. A pesquisa é caracterizada como descritiva e exploratória, utilizando uma abordagem quantitativa e qualitativa. A coleta de dados foi realizada através de um questionário adaptado por Albuquerque (2013) baseado no Modelo de Walton (1973). Houve retorno de, aproximadamente, 82% dos questionários entregues. Os resultados apontaram que os servidores estão satisfeitos com a maioria dos fatores que compõe o Modelo de Walton (1973), porém foram identificados quatro fatores que, na percepção dos servidores, podem influenciar negativamente a QVT: falta de equidade salarial externa; o stress e a fadiga provocada pela carga horária; a interferência do trabalho na vida pessoal e a ausência de ações voltadas ao entretenimento e ao lazer. Foram sugeridas, ao final do trabalho, algumas propostas de intervenção para estes problemas. / Work plays a central role in the life of man, and can be a source of suffering for the worker, causing, in some cases, physical and mental illness. The quality of life at work can contribute to make the work environment healthier to the worker, providing greater well-being and satisfaction. This paper aims to investigate the perception of the employees about the Quality of Life in the Work at the Rectory of IFSULDEMINAS. To achieve this goal the work was divided into eight parts: the introduction; work considerations; the models of analysis of Quality of Life at Work; The methodological procedures; data analysis; final considerations and intervention proposal. The research is characterized as descriptive and exploratory, using a quantitative and qualitative approach. There was a return of approximately 82% of the questionnaires delivered. The results indicate that the servers are satisfied with most of the factors that compose the Walton Model (1973), but four factors that, in the perception of the servers, can negatively influence the Quality of Life in the Work: lack of external wage equity ; Stress and fatigue caused by the workload; The interference of work in personal life and the absence of actions focused on entertainment and leisure. Some intervention proposals for these problems were suggested at the end of the study.

Facade: An Entertainment is a composition for six instrumentalists and reciter based on Edith Sitwell's "Facade" poems. While much has been written regarding this composition in general terms, relatively little has been said concerning the relationship between the poetry and the music. The purpose of this study is to examine this relationship and to provide a more in-depth analysis of the music than has previously been published. Several works that may have influenced Walton in the composition of Facade: An Entertainment and Facade II will also be examined.

This research describes a large, newly-recorded archaeological site in the Upper Apalachicola River valley, northwest Florida, and a private collection of artifacts from it, as well as test excavations, three-dimensional modeling, clay/pottery sourcing through chemical analysis, and direct radiocarbon dating of ceramics to relate the site with regional archaeological chronologies and settlement patterns. A University of South Florida (USF) 2013 field school conducted excavations at the multicomponent midden on the western floodplain of the Apalachicola River called the McKinnie site (8JA1869). Students collaborated with a local collector and family members to learn about the site's history. Data from the collection and excavations show that the site was inhabited through four thousand years of prehistory, serving as a rich seasonal resource base for local people in the area starting in the Middle Archaic Period, and as a small place of occupation during the Woodland Period, until people moved out into the river valley to live in farming villages. We also investigated a series of fascinating features, stored in the private collection and excavated by USF, which may have been intentionally buried at the site up to 5500 years ago. They may be evidence of some ancient ochre processing to obtain pigments, or some other special activity.

The history of contact with Europeans for Native Americans and the Tlingit people in particular has been well documented as one of extreme pain, suffering, and injustice. It was "survival time" for the Tlingit and very difficult choices had to be made. The life of one Tlingit man, Rudolph Walton, born in Sitka, Alaska in 1867, illuminates this critical time in the history of the Tlingit people. This dissertation is ah exploration of the interplay between competing cultures and interests and it is a quest to understand who Rudolph Walton was and how his life and the choices he made are connected to the larger historic themes and cross-cultural issues in Alaska Native education and religious life. In addition to providing a look at history and at cultural change through an individual's life, choices and experiences, this dissertation is also about the connection between my ancestors' choices and the impact those choices had on the survival of a people. It is at once a macro view and a micro view of the impact of history on Indian people. After the purchase of Alaska by the United States traditional Tlingit life changed forever. The Tlingit were forced on a daily basis to balance demands and pressures made by various Christian religious groups and the U. S. government. They also had to contend with the prejudice of the average American citizen. Most Native American history has been limited to the use of records written by Europeans and Americans. Our understanding of that history is limited because the voice of the Native American is rarely heard. This dissertation fills a gap in the history of Southeast Alaska through an examination of the life of Rudolph Walton. The life of Mr. Walton is important because he left us with a unique set of documents which help us to understand the difficulties he had to face as a Tlingit man during a critical time in the history of Southeast Alaska.

En este trabajo propongo una definición pragmática de la falacia de petición de principio. En la primera parte considero y rechazo la sugerencia de Frank Jackson de que la argumentación posee otro fin además del de convencer racionalmente a nuestro interlocutor de que algo es el caso. En la segunda parte ofrezco la definición. En la tercera parte hablo brevemente acerca de la representación de argumentos por medio de grafos. Finalmente, en la cuarta parte aplico la definición propuesta a algunos ejemplos de argumentos.---A Pragmatic Definition of the Begging the Question Fallacy”. A pragmatic definition of the Begging the question fallacy is presented in this paper. In the first part of it I consider and reject Frank Jackson’s suggestion according to which argumentation possesses a different end than rationally persuading an audience that something is the case. The definition is presented in part II. Part III refers briefly to the representation of arguments through graphs. Finally, in part IV, the proposed definition is applied to some argument examples.
