Cabrejo, Cobián José Carlos. "La metaficción: De Don Quijote de la Mancha al cine contemporáneo." Master's thesis, Tesis digitales - UNMSM, 2013. http://cybertesis.unmsm.edu.pe/handle/cybertesis/3454.
Full textAbstract:
En el cine contemporáneo hay una tendencia en la que filmes son metaficciones, es decir, son ficciones que hacen referencia a otras ficciones o que reflexionan sobre su condición de tales. Algunas películas que poseen esa característica son muy distintas entre sí: un filme paródico de terror como Scream, la máscara de la muerte de Wes Craven (1996), o una película experimental como El Camino de los Sueños (2001) de David Lynch. Incluso un documental como Grizzly man (2005) de Werner Herzog tiene ese rasgo.
En ese sentido, estas películas tienen otro aspecto en común: en términos generales, uno nota que muchos de sus mecanismos metaficcionales son los mismos que estructuran la clásica novela española Don Quijote de la Mancha. ¿El carácter metaficcional de la obra de Miguel de Cervantes ha influido en el devenir narrativo/discursivo del cine contemporáneo o ha llegado a anteceder muchas de sus características más saltantes? Esa es una pregunta que la tesis responde, y afirmativamente.
En este sentido, la presente investigación tuvo como objetivo primordial descubrir si las películas ya referidas (Scream, Grizzly man y El camino de los sueños) emplean los mismos mecanismos metaficcionales que articulan la obra Don Quijote de la Mancha. La trascendencia de esta tesis pasa por el hecho de que aquellas cintas representan tendencias fundamentales del cine contemporáneo. Scream forma parte de aquel tipo de cine ficcional de consumo masivo, que siempre está presente en las multisalas; Grizzly man es un largometraje que aparece en tiempos en que el documental (además del “falso documental”) ha adquirido una atención muy especial; y El camino de los sueños representa a un cine de pretensiones artísticas, “de autor”, que circula en festivales, pero que además es objeto de culto, a través del consumo en formato de video. La condición metaficcional de Don Quijote de la Mancha está presente en estas tres películas, a pesar de sus notorias diferencias.
Por ello, el tema de investigación de esta tesis permitirá abrir un enfoque novedoso a las relaciones que hay entre la obra más importante de Cervantes y el cine. Si bien existen investigaciones y una cierta bibliografía sobre las relaciones de Don Quijote de la Mancha con el lenguaje de las imágenes en movimiento, no existe en la actualidad un estudio profundo sobre las estrategias metaficcionales de la novela que habrían sido llevadas a cabo por los filmes en la actualidad.
En consecuencia, se demostrará la vigencia de la obra literaria que, para muchos, es la más importante de la lengua española. Se constatará que Don Quijote de la Mancha no es sólo una obra maestra de la narrativa moderna, sino una de alcances posmodernos y hasta hipermodernos (en palabras de Gilles Lipovetsky y Jean Serroy), al identificarse relatos cinematográficos contemporáneos que recogen muchos de sus procedimientos narrativos/discursivos de vertiente metaficcional.

Full textAbstract:
Desde 1946, cuando Sigerist usó por primera vez el término promoción de la salud, esta ha venido ocupando un papel preponderante en el logro de mejores condiciones de salud, realizándose múltiples reuniones mundiales para desarrollar el tema y plantear objetivos para mantener y mejorar la salud de las poblaciones; en esta perspectiva en el año 2006, el Ministerio de Salud presentó el modelo de abordaje de promoción de la salud considerando siete ejes temáticos, sin embargo, no se ha encontrado bibliografía que permita evidenciar la eficacia de este modelo de abordaje. Objetivo: Identificar si hay asociación entre el nivel de los conocimientos y prácticas en promoción de la salud de las familias la urbanización Constanzo, Callao-Perú en el año 2013. Materiales y métodos: El estudio es de diseño observacional de tipo transversal, se entrevistaron un total de 100 jefes de familia, con un instrumento diseñado de acuerdo al modelo de abordaje de promoción de la salud del MINSA, obteniéndose 79 encuestas válidas para el análisis. Resultados: En el 64.6% de los casos el jefe de familia fue el padre y la edad promedio fue de 51 años. 24.05% de los jefes de familia tienen nivel de conocimientos mayor en promoción de la salud y 20.25% en prácticas. Se encontró asociación entre el nivel de conocimientos y prácticas en 5 de los 7 ejes temáticos. Conclusiones: Tener un nivel de conocimientos mayor/intermedio está asociado a tener un nivel de prácticas mayor en promoción de la salud, al igual que el ingreso económico personal mensual.
Palabras clave: Promoción de la salud, conocimientos, prácticas, asociación.Introduction: Since 1946, when Sigerist first used the word health promotion, this has occupied an important role in achieving better health, multiple global meetings have been executed to develop the theme and set objectives to maintain and improve health of populations; in this perspective in 2006, the Ministry of health introduced the model approach to health promotion based on seven themes, however, it was not found literature to assess the effectiveness of this model. Objective: To identify if there is an association between the level of knowledge and practice in health promotion for families Constanzo urbanization, Callao, Peru in 2013. Materials and methods: The study is an observational cross-sectional design, 100 heads of households were interviewed with an instrument designed according to the model approach to health promotion, finally 79 instruments were surveys for analysis. Results: In 64.6 % of cases the household head was the father and the average age was 51 years. 24.05% of household heads have higher level of knowledge in health promotion and 20.25 % in practice. Association between the level of knowledge and practice was found in 5 of the 7 themes. Conclusions: To have a higher/intermediate level of knowledge is associated with having a higher level of practices in health promotion, as well as monthly personal economic income. Keywords: Health promotion, knowledge, practices, association.

Hass, Nicolette P. "The power of teams: Do self-managing work teams influence managers' perceptions of potency?" Thesis, University of North Texas, 2005. https://digital.library.unt.edu/ark:/67531/metadc4961/.
Full textAbstract:
The present study examined the perceptions of teams and managers on team potency levels as a function of stage of team development. Drawing from the power and influence literature, potency was established as a means by which to assess team's internal dynamics. Stage of team development was separated into four categories including pseudo, potential, real and high performance teams. Archival data included 45 teams and managers gathered from the manufacturing and service industries. Results indicated a significant linear relationship between team perceptions of team potency and stage of team development. Additionally, potency perceptions of teams significantly differentiated between the four stages of team development. Manager perceptions of team potency produced non-significant results. Possible explanations of the results as well as implications for practice and future research are provided.

Marshall, Esther. "Identity, Power, and Conflict in Preschool Teaching Teams." BYU ScholarsArchive, 2017. https://scholarsarchive.byu.edu/etd/6714.
Full textAbstract:
Despite the common occurrence of teaming in preschool classrooms, very little research has explored the experiences of teachers working in such a context. Due to a high turnover of preschool teachers and a recent change in the educational requirements of lead teachers in Head Start, it is anticipated that the number of young and inexperienced lead teachers is likely to increase. The purpose of this case study research is to illuminate the teaming relationships between young, recently qualified lead teachers and their assistants working together within one classroom. Over the course of a school year, interviews and observations were conducted of two Head Start teaching teams. Five major themes were revealed through data analysis: understanding of roles; organization of work; use and resistance of power; development and management of conflict; and support from within and outside the team. Analysis across the findings of both cases showed that identity and power played a central role in team functioning. The teachers' identities, perceived threats to their identities, and their understanding of the power differential played a significant role in the way the teams organized their work, the way the teachers viewed their roles within the team, and the conflict and support they experienced. Conclusions of the study are discussed through the lens of identity process theory and elements of Bourdieu's theory of power and practice. Implications for teacher professional development and the need for increased institutional support for teaming in preschool is presented.

Muitos adjetivos podem ser empregados para descrever o processo legislativo brasileiro. Criativo é um deles. No segundo mandato do presidente Lula, foram identificados questionamentos de parlamentares criticando a recorrente inclusão de matérias estranhas ao conteúdo original de medidas provisórias, procedimento vedado pela lei complementar nº 95 e pela resolução nº 1, de 2002-CN. A literatura norte-americana, exclusiva sobre o assunto, se refere a esse tipo de violação regimental como unorthodox lawmaking e denomina as leis aprovadas com múltiplos temas omnibus legislation. No Brasil, essa abordagem teórica é incipiente e não tem tratado desses aspectos mais específicos. O trabalho em questão utilizou a metodologia de análise de conteúdo qualitativo (QCA) para identificar os assuntos presentes nas versões originais de medidas provisórias editadas pelos presidentes e nas versões finais, denominados projetos de lei de conversão, aprovados pelo Congresso Nacional. Identificou-se que conteúdos eram propostos pelos presidentes, adicionados e aprovados pelos congressistas e sancionados ou vetados pelos chefes do Executivo. Foram analisadas 468 proposições propostas e convertidas em lei entre 11 de setembro de 2001 – data de promulgação da Emenda Constitucional 32, que modificou o rito de tramitação de medidas provisórias – e 31 de dezembro de 2011. Foram encontradas evidências que demonstram a corresponsabilidade entre presidentes e congressistas pela violação das normas regimentais que vedam o tratamento de matérias diversas entre si em uma mesma proposição legislativa, a coocorrência de assuntos distintos em proposições e leis convertidas independentemente de afinidade temática entre eles e o aumento da probabilidade de veto presidencial à medida que aumenta a quantidade de conteúdos presente no projeto de lei de conversão aprovado pelos congressistas. ______________________________________________________________________________ ABSTRACT
Many adjectives can be used to describe the brazilian legislative process. Creative is one of them. During president Lula’s second term, some congressmen criticized the recurrence of a practice prohibited by complementary law nº 95 and congress resolution nº 1, 2002-CN: the amendment of presidential decrees (known as provisory measures) with content unrelated to its original subject. The american literature, exclusive on the matter, refers to this type of procedural violation as unorthodox lawmaking and defines legislative packages with several subjects as omnibus legislation. In Brazil, this theoretical approach is incipient and has not yet assessed this specific point. This research was based on qualitative content analysis methodology (QCA) to identify the subjects in decrees presented by presidents to the Congress and in the final versions approved by the Legislative, identifying which matters were proposed by the president, annexed and approved by congressmen and senators and which were enacted or vetoed by the chief of the Executive branch. There were 468 decrees (provisory measures) analyzed, presented and enacted between September 11, 2001 – when Constitutional Amendment 32 was enacted and changed the legislative process for provisory measures – and December 31, 2011. The evidences found demonstrate the mutual responsibility between presidents and congressman for the violation of procedural rules that prohibit propositions with several subjects and non-germane amendments, the co-occurrence of contents in decrees and enacted laws regardless of connexion between themes and higher probability of presidential veto on texts approved by Congress with more types of content.

Walter, Bruno Eduardo Procopiuk. "O dispositivo do tempo e a constituição do sujeito pesquisador." Universidade Estadual de Maringá, 2014. http://repositorio.utfpr.edu.br/jspui/handle/1/1083.
Full textAbstract:
Inspirando-se em Michel Foucault, especialmente em suas contribuições acerca das relações de poder e da ética do cuidado de si, esta pesquisa teve por finalidade responder o seguinte problema: de que forma se dá a constituição do sujeito pesquisador, na Universidade Estadual de Maringá, a partir do dispositivo do tempo? Partiu-se, assim, do método genealógico, presente em Nietzsche e retomado pelo filósofo francês, para compreender as relações de forças por meio das quais o pesquisador é produzido. Ressalta-se que a genealogia não pressupõe essências imutáveis, dadas a priori, pois, para ela, o próprio sujeito é compreendido enquanto efeito de um determinado estado de forças. Assim, buscou-se o conhecimento das condições e circunstâncias nas quais o sujeito pesquisador nasceu,desenvolveu-se e modificou-se ou, em outras palavras, buscou-se seu nascimento empírico.Para compreender a constituição do sujeito pesquisador, a categoria de dispositivo teve papel fundamental, já que serviu como operador metodológico auxiliando na análise das práticas discursivas, de poder e de subjetivação. Dentre os diversos dispositivos envolvidos na constituição do sujeito pesquisador, optou-se por enfocar o dispositivo do tempo. Este foi proposto enquanto uma hipótese teórica pelo autor deste trabalho e teve por finalidade dar visibilidade ao campo de forças no qual o pesquisador é engendrado. A análise desse dispositivo recorreu a elementos diversos e heterogêneos, tais como editais, regulamentos,leis, páginas da internet, entre outros. Também foram realizadas 9 entrevistas e consultadas outras 21 (vinte e uma) realizadas por Gois (2012,2013). A partir das análises realizadas foi possível desenhar uma cartografia das linhas de produção da subjetividade do pesquisador, percebendo-se, por meio da escola-universidade, o sequestro de sua existência. Notou-se um imperativo para que o tempo do pesquisador seja cada vez mais utilizado de forma exaustiva e produtiva. Contribui para isso uma série de elementos como as bolsas de produtividade em pesquisa (ofertadas por meio de editais do Conselho Nacional de Desenvolvimento Científico e Tecnológico), o currículo lattes, as avaliações dos cursos de pós-graduação (realizados pela Coordenação de Pessoal de Ensino Superior), dentre outros. Contudo, se o dispositivo do tempo age sobre os pesquisadores dando-lhes certos contornos, surgem, em oposição, as resistências – expressas especialmente por meio do exercício da reflexão enquanto uma prática de liberdade. Diante disso, como conclusão, ressaltou-se que a forma pesquisador encontra na Universidade um lugar privilegiado de ser. Há, entretanto, à margem dessa moldura que constitui o pesquisador nas universidades sujeitos que fazem pesquisa e que escapam às formas de subjetivação sofridas pelo dispositivo do tempo. Ressalta-se, desse modo, a necessidade de criar outras formas de existência e subjetivação que transponham o dispositivo do tempo.Inspired by Michel Foucault, especially in his contributions on the power relations and ethics of self-care, this research aimed to answer the following problem: how is the researcher subject constituted , in the State University of Maringá, from the device of time? The author of this work used the genealogical methodol present in Nietzsche and retaken by the French philosopher to understand the power relations through which the researcher is produced. It is important to remember that the genealogy does not presuppose immutable essences which are given a priori, because, for it, the subject is understood as the effect of a given state forces. Thus, we sought to understand the conditions and circumstances in which the researcher subject was born, developed and changed, or, in other words, we sought his empirical birth. In order to understand the formation of the researcher subject, the category of device had fundamental importance, since it served as methodological operator aiding in the analysis of discursive practices, power practices and subjectivity process. Among the various devices involved in the constitution of the researcher subject, we chose to focus on the device of time. This one was proposed as a theoretical hypothesis by the author of this work and aimed to give visibility to the field of forces in which the researcher is engendered. The analysis of this device used several and heterogeneous elements, such as public notices, regulations, laws,websites, among others. Nine interviews were also conducted and other twenty-one (made by Gois, 2012, 2013) were consulted. From the analysis it was possible to draw a cartography of the production lines of the researcher's subjectivity, perceiving through school-university the kidnapping of his existence. It was noted a must for the time of the researcher to be increasingly used in an extensive and productive way. A number of factors such as reward research productivity (given by of the Conselho Nacional de desenvolvimento Científico e Tecnológico), the lattes curriculum, assessments of post-graduate (made by the Coordenação de Pessoal de Ensino Superior), among others contributed for this. If on one hand the device of time acts on researchers by giving them certain contours, on the other had resistance emerges in opposition – especially expressed through the exercise of reflection as a practice of freedom. Thus, in conclusion, it was emphasized that the researcher form finds a special place to be in the University. There are, however, researcher subjects who are escaping the forms of subjectivity experienced by the device of time that are outside this frame that constitutes the researcher in the universities. It is noteworthy, therefore, the need for other forms of existence and subjectivity that transpose the device of time.

Full textAbstract:
This study introduces Texas Hold'em Poker as a research interest and discusses the use of poker in studying interpersonal deception. The first section reviews relevant literature in the study of deception and detection in order to answer: 1) What is the base rate of deceptive attempts for poker players? 2A) What types of tells are exhibited? 2B) What inconsistent nonverbal behavior does each player exhibit? This research also hypothesizes that bluffers will engage in consistent nonverbal behavior in bluffing and non bluffing sets. The second section describes the methods used. A videotaped poker game was recorded and analyzed. Twenty nonverbal behaviors were coded and frequency of behavior was calculated. The third section describes the results of the analysis: base rate, tells, and inconsistencies. Finally, the last section discusses the results, conclusions, limitations, and further avenues of study.Department of Communication Studies

Full textAbstract:
Most of the existing poker agents using case-based reasoning (CBR) are based on imitation of other poker agents and have weak capabilities of adapting their own strategies to different opponents or playing styles. We address these concerns in the development of UpperCase, a heads up no-limit Texas Hold'em poker agent representing a new approach to the application of CBR in poker. Using methods of perfect information hindsight analysis, the poker agent attempts to more accurately determine the quality of poker decisions. Through extensive exploration of the quality of different decisions, UpperCase is able to invent new poker strategies. The agent also tries to recognize different opponents by observing their actions and perform adaptation accordingly. Experimental results suggest that the agent is able to successfully create new profitable strategies, as well as achieve increased performance by dynamically changing its strategy during play.

Full textAbstract:
The problem with which this study was concerned is the
political influence of community/junior college chief executive
officers (CEOs) and campus presidents on the state legislature, both directly and indirectly, in the funding of community colleges in Texas. Perceptions of effectiveness were recorded by survey from campus presidents and CEOs as well as from legislators and key legislators. In addition, interviews were conducted with several key legislators and the chief administrators of the two statewide community college organizations.
The purpose of the study was to analyze the policy-making process in Texas of which community/junior colleges are a part. The influential relationships and interactions of the sixty-five CEOs and campus presidents of the public community college districts and campuses in Texas were analyzed after a survey instrument was administered. Perceptions of rank—and—file legislators were gathered through use of another survey instrument and perceptions of key legislators were gathered in the same manner but with the addition of a personal interview. Certain questions were asked of them concerning interactions and communication with leaders of community colleges. With the legislators and the presidents certain demographic data was collected and analyzed as a part of the study.
Among the findings, campus presidents and CEOs do not have sufficient levels of acquaintance, interaction and communication to heavily influence local people whom they consider powerful in state funding of community colleges. Furthermore, legislators do not receive enough communication from powerful local group members to positively influence their decisions regarding community college funding. Presidents and CEOs from the metropolitan districts communicate most often with their legislators followed by those from rural districts. Board members from the metropolitan districts are most active in communicating with their legislators. Finally, legislators view the community college nearest them as equal to or better than community colleges statewide.

The purpose of this study is to develop a strategy for investment in power generation technologies in the future given the uncertainties in climate policy and fuel prices. First, such studies are commonly conducted using deterministic methods which assume a given likelihood of the carbon and gas price levels. In this study a probabilistic approach is used to address these uncertainties. Secondly, capacity expansion models conventionally apply average estimates to predict the amount of power that each generator will produce based on the technology chosen. I propose an alternate method which determines the actual generation hour-by-hour of a generator. Using this method, I also capture the variability of wind generation across the year. To accomplish this goal, I used the Electric Reliability Council of Texas (ERCOT) as a case study. I investigated the effect of different scenarios of generation technology investments projected over a period of twenty years. I conducted two sets of analysis; first assuming that Carbon Capture and Storage (CCS) technologies will be available after 2020, then assuming that they will not. Using a dispatch model, I simulated the hours of a load duration curve for 2020 and 2030. In the first period 2010-2020, I assumed the price of carbon to either be $0 or $50/ton CO2. In the second period, I take the carbon price to be at either a low of $25/ton of CO2 or a high of $100/ton of CO2 . The price of natural gas used was either a high of $15/MMBtu or a low of $3/MMBtu in both periods. Using a Monte Carlo, I sample the wind generation based on the season and the time of day. The system costs with the new investment scenarios were then evaluated in a decision tree to establish the socially optimal solution. I find that the optimal strategy to be taken today depends on the availability of CCS technologies in 2030. Assuming that there is CCS in 2030, the more dominant strategy would be to build natural gas generators today. If we assume that there is no CCS in 2030, the strategy would depend on the probabilities of the levels of gas and carbon prices in 2020.

Full textAbstract:
The debate on power (puissance) remains open. The literature in International Relations (IR) understands this concept as a relation, a resource, a structure, or a social element that changes the behaviour, the position, or the identity of an actor. Power is therefore understood as a "cause". Yet, at the methodological level the causal conception of power is not fruitful. This thesis offers a non-causal conceptualization of power. After reviewing the IR literature on power, it shows that power is a spectacular instant-image that emanates from the "screenal " space. This definition is based upon the under-researched variables of "time" and "space" of power. The argument relies both on an "instantaneous" temporal understanding (phenomenology, factual history) and on a "videopoliticized" spatial understanding (television screen as political space) of international affairs.

Cette thèse aborde la laïcité en tant que notion à interroger et à placer dans son contexte historique, mais aussi politique et social. La laïcité est un type d’individuation psychique et collective qui apporte à ceux qui la pratiquent un apaisement des relations interpersonnelles, permettant la libre expression des opinions. D’une part, la laïcité sera distinguée de la tolérance et de la sécularisation, toutes deux nécessaires à son déploiement ; d’autre part, seront discutées, au sein même de la laïcité, les postures combatives anti-cléricales et inversement, celles qui permettent la constitution d’un espace apaisé de libre expression (qui suppose la liberté de conscience)This thesis addresses laicity as a notion which is to be questioned and set in its context – historical, but also political and social. Laicity is a particular form of psychical and collective individuation which brings to those who practice it an appeasement in their interpersonal relations, allowing for the free expression of opinions. On the one hand, laicity will be distinguished from toleration and secularization, which are both necessary for its development; on the other hand, there will be a discussion, within the framework of laicity, of the twin postures of combative anti-clericalism, and its opposite which allows the constitution of a space of pacified free expression (which supposes a freedom of conscience)

The aim of this investigation is to understand how international project teams enable mature multinational enterprises (MNEs) to cope with knowledge diversity and political activity, two well-known disruptive organizational phenomena, in order to leverage their innovative potential and competitive capabilities. To answer this question a longitudinal multi-case study has been designed to collect in-depth qualitative data from three large-scale international projects conducted by a focal MNE and an array of its subsidiaries. In a dialectic way, data collected has been used both to enhance the dynamic knowledge change framework provided by contemporary sociology and to explain the complex mechanisms that make international project teams an increasingly used organizational tool. As a result, knowledge change (and thus innovation) has been found to hinge on a dynamic balance between power and politics which is favored by conditions that are inherent to these organizational settings. Finally, a model describing the mechanisms that enable international project teams to drive knowledge diversity and political activity towards innovation and knowledge change within MNEs has been developed.L'objectiu d'aquesta investigació és entendre com els equips de projectes internacionals permeten a les empreses multinacionals madures fer front a la diversitat de coneixements i l'activitat política, dues reconegudes fonts de problemes organitzacionals, amb la finalitat de potenciar les seves capacitats d'innovació i potencial competitiu . Per respondre a aquesta pregunta un estudi longitudinal embolicant casos múltiples s'ha desenvolupat per recollir dades qualitatives en profunditat des de tres grans projectes internacionals a càrrec d'una empresa multinacional focal i una gran varietat de les seves filials. D'una manera dialèctica, les dades recollides han estat utilitzats tant per millorar el marc del canvi dinàmic del coneixement proposat per la sociologia contemporània i explicar els complexos mecanismes que fan que els equips de projectes internacionals en una eina cada vegada més utilitzada per aquestes organitzacions. Com a resultat, es mostra que el canvi d'un determinat coneixement depèn d'un equilibri dinàmic entre poder i política afavorit per les condicions que són inherents a aquests formats organitzacionals. Finalment, es desenvolupa un model que detalla els mecanismes que permeten als equips de projectes internacionals impulsar la diversitat de coneixements i l'activitat política cap a la innovació i el canvi del coneixement dins de les empreses multinacionals madures.
El objetivo de esta investigación es entender cómo los equipos de proyectos internacionales permiten a las empresas multinacionales maduras hacer frente a la diversidad de conocimientos y la actividad política, dos reconocidas fuentes de problemas organizacionales, con el fin de potenciar sus capacidades de innovación y potencial competitivo. Para responder a esta pregunta un estudio longitudinal envolviendo casos múltiplos se ha desarrollado para recoger datos cualitativos en profundidad desde tres grandes proyectos internacionales a cargo de una empresa multinacional focal y una gran variedad de sus filiales. De una manera dialéctica, los datos recogidos han sido utilizados tanto para mejorar el marco del cambio dinámico del conocimiento propuesto por la sociología contemporánea y explicar los complejos mecanismos que hacen que los equipos de proyectos internacionales en una herramienta cada vez más utilizada por estas organizaciones. Como resultado, se muestra que el cambio de un determinado conocimiento depende de un equilibrio dinámico entre poder y política favorecido por las condiciones que son inherentes a estos formatos organizacionales. Por fin, se desarrolla un modelo que detalla los mecanismos que permiten a los equipos de proyectos internacionales impulsar la diversidad de conocimientos y la actividad política hacia la innovación y el cambio del conocimiento dentro de las empresas multinacionales maduras.

Full textAbstract:
Background Within trauma teams, effective communication is necessary to ensure safe and secure care of the patient. Deficiencies in communication are one of the most important factors leading to patient harm. Time is an essential factor for rapid and efficient disposal of trauma teams to increase patients’ survival and prevent morbidity. Trauma team training plays an important role in improving the team’s performance, while the leader of the trauma team faces the challenge of coordinating and optimizing this performance. Aim The overall aim of this thesis was to analyse how members of trauma teams communicated verbally and non-verbally during trauma team training in emergency settings, and how the leaders were positioned or positioned themselves in relation to other team members. The aim was also to investigate the use of a communication tool, closed-loop communication, and the time taken to make a decision to go to surgery in relation to specific factors in the team as well as the leader’s position. Methods Eighteen trauma teams were audio and video recorded and analysed during regular in situ training in the emergency room at a hospital in northern Sweden. Each team consisted of six participants: two physicians, two nurses, and two enrolled nurses, giving a total of 108 participants. In Study I, the communication between the team members was analysed using a method inspired by discourse psychology and Strauss’ concept of “negotiated orders”. In Study II, the communication in the teams was categorized and quantified into “call-outs” and “closed-loop communication”. The analysis included the team members’ background data and results from Study I concerning the leader’s position in the team. Poisson regression analyses were performed to assess closed-loop communication (outcome variable) in relation to background data and leadership style (independent exploratory variables). In Study III, quantitative content analysis was used to categorize and organize the team members’ positions and the leaders’ non-verbal communication in the video-recorded material. Time sequences of leaders’ non-verbal communications in terms of gaze direction, speech time, and gestures were identified separately to the level of seconds and presented as proportions (%) of the total training time. The leaders’ vocal nuances were also categorized. The analysis in Study IV was based on the team members’ background data, the results from Study I concerning the leader’s position in the team, and the categorization and quantification of team communication from Study II. Cox proportional hazard regression was performed to assess the time taken to make a decision to go to surgery (outcome variable) in relation to background data, the leader’s position, and closed-loop communication (independent variables). Results The findings in Study I showed that team leaders used coercive, educational, discussing, and negotiating repertoires to convey knowledge and create common goals of priorities in work. The repertoires were used flexibly and changed depending on the urgency of the situation and the interaction between the team members. When using these repertoires, the team leaders were positioned or positioned themselves in either an authoritarian or an egalitarian position. Study II showed that closed-loop communication was used to a limited extent during the trauma team training. Call-out was more frequently used by team members with eleven or more years in the profession and experience of trauma within the past year, compared with team members with no such experience. Scandinavian origin, an egalitarian team leader and previous experience of two or more structured trauma courses were associated with more frequent use of closed-loop communication compared to those with no such origin, leader style, or experience. Study III showed that team leaders who gained control over the “inner circle” used gaze direction, vocal nuances, verbal commands, and gestures to solidify their verbal messages. Leaders who spoke in a hesitant voice or were silent expressed ambiguity in their non-verbal communication, and other team members took over the leader's tasks. Study IV showed that the team leader’s closed-loop communication was important for making the decision to go to surgery. In 8 of 16 teams, decisions on surgery were taken within the timeframe of the trauma team training. Call-outs and closed-loop communication initiated by the team members were significantly associated with a lack of decision to go to surgery. Conclusions The leaders used different repertoires to convey and gain knowledge in order to create common goal in the teams. These repertoires were both verbal and non-verbal, and flexible. They shifted depending on the urgency of the situation and the interaction within the team. Depending on the chosen repertoire, the leaders were positioned or positioned themselves as egalitarian and/or authoritarian leaders. In urgent situations, the leaders used closed-loop communication as part of a coercive repertoire, and called out commands and directed requests to specific team members. This repertoire was important for making the decision to go to surgery; the more closed-loop communication initiated by the leader, the more likely that the team would make a decision to go to surgery. Problems arose if the leaders were positioned or positioned themselves as either an authoritarian or an egalitarian leader. The leaders needed to be flexible and use different repertories in order to move the teamwork forward. It was notable that higher numbers of call-outs and closed-loop communication initiated by the team members decreased the probability of making the decision to go to surgery.

Full textAbstract:
This study examined different funding methods for financing public education in order to solve the problems associated with large numbers of school districts and great disparities in property wealth without abandonment of property tax as the major revenue source. Using enrollment and State Property Tax Board data for the 1,061 school districts in Texas in 1986-87, four alternative funding plans were studied to compare the equity and fiscal impact of each on public school finance in Texas. The state and local shares of the total cost of education were computed using a combination of three per-pupil expenditure levels and four funding formulas. The per-pupil expenditure levels used were $3,850, $4,200, and $4,580. The formulas used were representative of a full state funding plan, a percentage equalization plan, a power equalization plan, and a foundation school program plan.
Since each of the four plans used significantly higher per-pupil expenditure values, all required a greater monetary investment on the part of the state. However, all plans were found to be equalizing in nature if set per-pupil expenditure values were maintained and no local enrichment was permitted. In addition, each of the four plans, as studied, met the fiscal neutrality standard of the 1987 Edqewood v. Kirbv case. The percentage and power equalization plans required less monetary investment on the part of the state than either full state funding or the foundation school program.
As a result of the study, it is recommended that the state consider a combination of plans. For example, the state could employ a full state funding model up to the $3,850 per-pupil expenditure level with added permissible local millage being limited and power equalized. In addition, while each of the plans studied reduces inequity, the increased cost of an adequate public school education suggests that the state consider other sources of revenue to fund public education. These could include personal or corporate income taxes.

Texas Hold'em poker provides an interesting test-bed for AI research with characteristics such as uncertainty and imperfect information, which can also be found in domains like medical decision making. Poker introduces these characteristics through its stochastic nature and limited information about other players strategy and hidden cards. This thesis presents the development of a Bayesian Case-based Reasoner for Poker (BayCaRP). BayCaRP uses a Bayesian network to model opponent behaviour and infer information about their most likely cards. The case-based reasoner uses this information to make an informed betting decision. Our results suggests that the two reasoning methodologies combined achieve a better performance than either could on its own.

This thesis examines the economic implications of using agriculturally based
feedstock for bio-energy production in East Texas. Specifically I examined the use of
switchgrass, rice straw, and logging residue as a feedstock for electrical power
generation in East Texas replacing coal.
To examine the effects of such a substitution, an environmental bio-complexity
approach is used to analyze the interactions of agricultural, technological, economic, and
environmental factors. In particular, lifecycle analysis (LCA) and Cost-Benefit analysis
is used.
The results show that as we use more bio-energy for power generation, we will
get less Greenhouse Gas (GHG) emission, which will be an environmental benefit in the
long run. The main problem is that cost increases. Current biomass feedstock production
costs are generally too high for biomass feedstock to replace coal in power generation.
However I find that GHG offset prices can make biomass economically attractive. In
particular GHG offset prices and forgiveness for the emissions from combustion based on photosynthetic absorption would raise the price people would be willing to pay for
biomass feedstock making it competitive.

Full textAbstract:
Texas currently maintains the highest installed nameplate capacity and does not require publicly available post-construction monitoring studies that examine the impacts of wind energy production on surrounding fauna. This thesis examines potential wind energy impacts on avian and bat species in Texas through a three-part objective. The first two objectives synthesize literature on variables attractive to species within wind development areas and estimate impacted ranges outside of Texas, based on studies examining wind energy's environmental impacts. The third objective focuses on Texas wind development potential for interaction with rare, threatened and endangered species of birds and bats using GIS analysis with a potential hazard index (PHI) model, which addresses broad-spectrum, high risk variables examined within the first two objectives. Assuming areas with higher wind speeds have potential for wind development, PHI values were calculated for 31 avian and ten bat species, based on an analysis of species range data obtained from the Texas Parks and Wildlife Department and wind data obtained from the National Renewable Energy Laboratory. Results indicate one avian species, Tympanuchus pallidicinctus, is at high risk for wind development interaction on an annual basis, with 20 species of birds and nine species of bats at higher risk during the spring season. This macro-scale approach for identifying high risk species in Texas could be used as a model to apply to other conterminous states' preliminary evaluation of wind energy impacts.

Full textAbstract:
This thesis is a study of the wireless embedded Internet implemented with a standardized set of protocols called 6LoWPAN (IPv6 over Low-power Wireless Personal Area Networks). 6LoWPAN enables efficient and adaptable use of IP in networks with low power and low bandwidth. Such a network is set up consisting of an Edge Router and two nodes called CC1180DB from Texas Instruments. A program called NanoHost Example was downloaded and run on the boards making them send data packages with amongst else the current RSSI (Received Signal Strength Indication) value. With a PC connected to the network, a program called NodeView was used to receive the data. NodeView is a product from Sensinode based on tabs that gives the user possibility to add and program a new tab. A new tab was created in NodeView, showing the received RSSI data in a graph as function of time. The program worked well and the data was reasonable compared to two indicator LED’s on the board. The conclusion is that 6LoWPAN and the associated software and libraries provide a relatively easy way to build long-lasting low power wireless networks. The technology has an endless number of possible applications for industry and individuals to use.

THIS PAPER AIMS to research historical artistic events such as Theatre and Cinema, theater text Oleanna by David Mamet (1992), as well as the film adaptation (1994) and the stage adaptation Brazilian (1995) by Ulysses Cruz. Through the work and its adaptations is made a detailed analysis of each language and the context in which they were reworked. For this it was necessary to think of the role of the author and theater director and film as well as the aesthetic and thematic choices in making an adaptation, among the questions: who wins materiality in this process? Moreover, among the discussions, such work also focuses the thematic study of the work, involving topics such as: the power, the politically correct, the student-teacher ratio in university and the issue of harassment, which allow us to think in contemporary society while a society increasingly fragmented and individualized, in which conflicts are increasingly evident, particularly the lack of otherness. In this context, where the ideals of social transformation? Where are the utopias? These are some more of the issues present in this work.O PRESENTE TRABALHO tem como proposta a investigação histórica de manifestações artísticas como o Teatro e o Cinema, através do texto teatral Oleanna de David Mamet (1992), bem como a adaptação cinematográfica (1994) e a adaptação para o palco brasileiro (1995) por Ulysses Cruz. Através da obra e suas adaptações é feita a análise minuciosa de cada linguagem e o contexto em que foram reelaboradas. Para isso foi necessário pensar no papel do autor e diretor teatral e cinematográfico, bem como nas escolhas estéticas e temáticas na feitura de uma adaptação, considerando, entre outras questões: o que ganha materialidade nesse processo? Além disso, o trabalho se debruça também no estudo temático da obra, que envolve temas como: o poder, o politicamente correto, a relação professor-aluno nas universidades e a questão do assédio, que nos permitem pensar na sociedade contemporânea como cada vez mais fragmentada e individualizada, apresentando conflitos cada vez mais evidentes, sobretudo pela falta de alteridade. Nesse contexto, onde estão os ideais de transformação social? Onde estão as utopias? Essas são mais algumas das questões presentes neste trabalho.

Les contrôleurs industriels font l’objet de changements de paramètres, de modifications, d’améliorations en permanence. Ils subissent les évolutions technologiques aussi bien matérielles que logicielles (librairies, système d’exploitation, loi de commande...). Malgré ces contraintes, ces contrôleurs doivent obligatoirement assurer toutes les fonctionnalités recouvrant le séquentiel, les protections, l’interface homme machine et la stabilité du système à contrôler. Ces fonctionnalités doivent être couvertes pour une large gamme d’applications. Chaque modification (matérielle ou logicielle) quoique mineure est risquée. Le debogage, l’analyse et la programmation sur site sont énormément coûteux surtout pour des sites de type offshore ou marine. Les conditions de travail sont difficiles et les tests sont réduits au strict minimum. Cette thèse propose deux niveaux de validation en plateforme d’expérimentation : un niveau de validation algorithmique que l’on appelle Validation par Interface Logicielle (VIL) traitée au chapitre 2 ; un niveau de validation physique que l’on appelle Validation par Interface Matérielle (VIM) traitée au chapitre 3. La VIL valide uniquement l’aspect algorithme, la loi de commande et la conformité des références au niveau calcul sans prendre en compte les signaux de commande physiques et les signaux de retour gérés par l’Unité de Gestion des Entrées/Sorties (UGES). Un exemple de validation d’un contrôleur industriel d’un ensemble convertisseur trois niveaux et machine asynchrone est traité dans le deuxième chapitre avec une modélisation particulièrement adaptée à la VIL. Le dernier chapitre traite la VIM sur différentes bases matérielles (Field Programmable Gate Array (FPGA), processeurs). Cette validation prend en compte l’aspect algorithme et les signaux de commande physique ainsi que les signaux de retour. On y présente plusieurs approches de modélisation, choisies selon la base matérielle d’implémentation du simulateur temps réel. Ces travaux ont contribué aujourd’hui à au processus de validation des contrôleurs dédiés aux applications Oil and Gaz et Marine de General Electric - Power Conversion © (GE-PC)Industrial controllers are always subjected to parameters change, modifications and permanent improvements. They have to follow off-the-shelf technologies as well as hardware than software (libraries, operating system, control regulations ...). Apart from these primary necessities, additional aspects concerning the system operation that includes sequential, protections, human machine interface and system stability have to be implemented and interfaced correctly. In addition, these functions should be generically structured to be used in common for wide range of applications. All modifications (hardware or software) even slight ones are risky. In the absence of a prior validation system, these modifications are potentially a source of system instability or damage. On-site debugging and modification are not only extremely expensive but can be highly risky, cumulate expenditure and reduce productivity. This concerns all major industrial applications, Oil & Gas installations and Marine applications. Working conditions are difficult and the amount of tests that can be done is strictly limited to the mandatory ones. This thesis proposes two levels of industrial controller validation which can be done in experimental test platform : an algorithm validation level called Software In the Loop (SIL) treated in the second chapter ; a physical hardware validation called Hardware In the Loop (HIL) treated in the third chapter. The SIL validates only the control algorithm, the control law and the computed references without taking into account neither the actual physical commands nor the physical input feedbacks managed by the Input/Output boards. SIL validation of the system where industrial asynchronous motor is fed and regulated by a three level Variable Speed Drive with a three level voltage source converter is treated in the second chapter with a particular modeling approach adapted to such validation. The last chapter presents the HIL validation with various hardware implementations (Field Programmable Gate Array (FPGA), processors). Such validation checks both the control algorithm and the actual physical Input/Output signals generated by the dedicated boards. Each time, the modeling approach is chosen according to the hardware implementation. Currently this work has contributed to the system validation used by General Electric - Power Conversion © (GE-PC) as part of their validation phase that is mandatory for Oil & Gas projects and Marine applications

The increasing U.S. dependence on imported oil; the contribution of fossil fuels to the
greenhouse gas emissions and the climate change issue; the current level of energy
prices and other environmental concerns have increased world interest in renewable
energy sources. Biomass is a large, diverse, readily exploitable resource. This
dissertation examines the biomass potential in Eastern Texas by examining a 44 county
region. This examination considers the potential establishment of a 100-megawatt (MW)
power plant and a 20 million gallon per year (MMGY) ethanol plant using
lignocellulosic biomass. The biomass sources considered are switchgrass, sugarcane
bagasse, and logging residues. In the case of electricity generation, co-firing scenarios
are also investigated. The research analyzes the key indicators involved with economic
costs and benefits, environmental and social impacts. The bioenergy production
possibilities considered here were biofeedstock supported electric power and cellulosic
ethanol production. The results were integrated into a comprehensive set of information
that addresses the effects of biomass energy development in the region. The analysis indicates that none of the counties in East Texas have sufficient
biomass to individually sustain either a 100% biomass fired power plant or the cellulosic
ethanol plant. Such plants would only be feasible at the regional level. Co-firing
biomass with coal, however, does provide a most attractive alternative for the study
region. The results indicate further that basing the decision solely on economics of
feedstock availability and costs would suggest that bioenergy, as a renewable energy, is
not a viable energy alternative. Accounting for some environmental and social benefits
accruing to the region from bioenergy production together with the feedstock economics,
however, suggests that government subsidies, up to the amount of accruing benefits,
could make the bioenergies an attractive business opportunity for local farmers and
investors.

O cinema, como um veículo para interpretação de um contexto histórico particular, mantém estreitas relações com a conjuntura na qual é concebido e visto. O diálogo entre filmes e história é focalizado neste trabalho através dos personagens femininos de quatro produções brasileiras: S. Bernardo (Leon Hirszman, 1972); Lição de amor (Eduardo Escorel, 1975); Parahyba mulher macho (Tizuka Yamasaki, 1983) and Eternamente Pagu (Norma Bengell, 1988). Esta pesquisa tenta compreender uma proposta de cinema político que leva às telas mulheres expressivas como protagonistas ou personagens essenciais na narrativa — elas se convertem em instrumentos para se questionar aspectos do poder que extrapolam a política institucional. Tais filmes pertencem a um contexto no qual as artes no Brasil enfrentam os efeitos de um governo ditatorial, como a censura e a repressão política, além do crescimento de uma indústria cultural. Cabe aqui discutir se a opção por observar aspectos subjetivos e relações pessoais, em cada uma das produções analisadas, acaba por produzir uma concepção distinta de política e de um cinema que busca a crítica social. Para além de elementos que sugerem aceitação do mercado cinematográfico e as limitações do contexto político, tais personagens femininas, apropriadas de décadas anteriores na história do Brasil, expressam certo olhar questionador sobre relações familiares, pessoais ou amorosas, ou mesmo sobre os papéis femininos na sociedade. Relações sociais cotidianas e conflitos subjetivos compõem, através das personagens femininas, um espaço para a análise do poder em suas múltiplas dimensões — em outras palavras, concebendo e vivenciando o privado como político.
Cinema, as a vehicle for na interpretation of a particular historical time, keeps close relation with the context in which it is conceived and seen. The dialogue between films and History is focused on this essay through the feminine characters of four Brazilian movies: S. Bernardo (Leon Hirszman, 1972); Lição de amor (Eduardo Escorel, 1975); Parahyba mulher macho (Tizuka Yamasaki, 1983) and Eternamente Pagu (Norma Bengell, 1988). It tries to understand a proposal of political cinema that puts on screen expressive women as principal or essential characters in the narrative – these women appear as instruments to question aspects of politics which go beyond the institutional politics. These films belong to a context in which Brazilian arts face the effects of a dictatorial government, such as censure and political repression, and also the increase of a cultural industry. It is worth discussing whether the option for observing subjective aspects and personal relationships, in each of these movies, ends up producing a differentiated conception of politics and a film focused on social criticism. Besides the elements that signal and acceptance of the film market and the limitations of the political context, these feminine characters, which belong to previous decades in Brazilian History, express such critical remark on personal, family and love relationships, or even on women’s role in society. Social relations in the daily routine and subjective conflicts compose, through the feminine characters, a space to analyze the power in its multiple dimensions – in other words, conceiving and living the private as political.

Full textAbstract:
Tout au long d'un puits géothermique basse énergie (jusqu'à 2000 mètres de profondeur), du ciment est utilisé dans les espaces annulaires entre les tubages et les formations géologiques environnantes. Son rôle est de garantir les étanchéités, la tenue mécanique des couches et la protection du tubage. La qualité et la tenue dans le temps de ces ciments sont importantes. Compte tenu du gradient géothermique, des circulations d'eau chargée en éléments chimiques au sein de l'aquifère et des fortes contraintes dues à la profondeur, l'hydratation du ciment est susceptible d'être influencée significativement. En effet, ces facteurs peuvent à long terme contribuer à une dégradation prématurée du puits. L'objectif de ce travail est d'étudier les effets des conditions environnementales des puits géothermiques (la température, la pression et les concentrations en NaCl) sur les propriétés physiques et mécaniques des pâtes de ciment en passant par une étude microstructurale poussée. Pour cela, plusieurs coulis de ciment ont été échantillonnés sur un chantier géothermique en Ile de-France. Sur ce chantier, le coulis ciment de classe G et le coulis de ciment allégé en bentonite sont utilisés tout au long du puits. Les pâtes de ciment durcies réalisées en laboratoire ont été étudiées en utilisant une méthodologie basée sur des mesures non destructives (vitesse du son, fréquence de résonance, perméabilité) et destructives (module de Young, résistance à la compression, conductivité thermique). Les propriétés thermiques et physico-mécaniques des pâtes de ciment durcies issues de ces mesures ont été couplées à des observations microstructurales par diffraction de rayon X, par microscopie électronique à balayage et par porosimétrie par intrusion de mercure. Les résultats ont montré que les analyses microstructurales sont corrélables avec les propriétés physico-mécaniques et qu'elles sont de bons indicateurs de l'état de ces ciments dans les puits. Ce travail de thèse propose une méthodologie de mesure fiable. En effet, les nombreux essais réalisés et leurs analyses ont permis de déterminer les relations qui permettent de prédire la résistance à la compression des pâtes de ciment d'un puits géothermique. Enfin et quels que soient les paramètres environnementaux appliqués, des relations empiriques ont pu être proposées. Ces dernières, en reliant les résultats de méthodes non destructives avec ceux de méthodes destructives permettront de déterminer les propriétés des pâtes de ciment d'un puits géothermique sans passer par des essais destructifsIn low energy geothermal wells (up to 2000 meters deep), cement is used in the annular space, between the casing and surrounding geological formations. Its role is to ensure the zonal isolation, the mechanical strength of the layers and the protection of the casing. The quality and stability over time of these cements are important. Given the geothermal gradient, water circulations loaded in chemical elements in the aquifer and strong confining stresses due to the depth, cement hydration is likely to be significantly influenced. Indeed, these factors may in the long term contribute to premature degradation of the well. The objective of this work is to examine the effects of environmental conditions of geothermal wells (temperature, pressure and concentrations of NaCl) on the physical and mechanical properties of cement pastes and microstructural inverstigations. Several grouts were sampled on a geothermal project in Ile de France. On this project, the class G cement grout and cement with bentonite grout are used throughout the well. Hardened cement pastes prepared in the laboratory were studied using a methodology based on non-destructive (ultrasonic wave velocity, resonance frequency, permeability) and destructive measurements (Young's modulus, compressive strength, thermal conductivity). Thermal and physico-mechanical properties of hardened cement pastes from these measures were coupled with microstructural observations by X-ray diffraction, scanning electron microscopy and mercury intrusion porosimetry. The results showed that the microstructural analyses concur with the physico-mechanical properties and are good indicators of the state of the cement in the well. This thesis proposes a reliable testing methodology. Indead, many tests and analyses provide relationships that predict the compressive strength of cement pastes a geothermal well. Finally, and irrespective of the environmental conditions applied, empirical relationships have been proposed. These link relations the results of non-destructive methods with those from destructive tests and can be used to determine the properties of cement pastes without carrying out destructive tests in geothermal wells

This study explores the relatively new phenomenon of online poker. More specifically, it elaborates on who the online poker player is, why s/he plays online poker, what the fascination of the game is, why s/he continues to play, and what the experience is. The study is delimited to focus on individuals who mainly play Texas hold’em online. The empirical material is based on semi-structured interviews with active online poker players, as well as on secondary data such as articles and literature. Both professional and amateur players are included among the respondents. The material has been coded and qualitatively analyzed. Earlier studies in the same field have also been brought to light and discussed, among which we especially centered on Reith’s theories about gambling and the gambler. Finally, the study concludes that the four factors primarily motivating the online poker player are excitement, money, social interaction, and the aspect of skill.

L'un des aspects important de la conception et de l'exploitation des grands réseaux de transport et d'interconnexion est le maintien de la sécurité du système. Cette sécurité concerne aussi bien les limites thermiques sur les ouvrages de transport que les limites de tension aux noeuds du réseau (contraintes d'isolation et de stabilité). A cet effet, le développement de méthodes nouvelles qui permettront à l'opérateur d'exploiter le réseau de façon à ce qu'aucun incident ne puisse causer les dépassements de limites de sécurité du système, est de plus en plus une nécessité. Cette thèse présente un algorithme général pour rendre plus efficace l'naisse de sécurité et donc permettre une analyse réellement systématique des incidents. Cet outil est basé sur l'utilisation des informations intrinsèquement contenues dans les résultats d'une analyse de sécurité systématique. Ces dernières peuvent être utilisées à des instants suivants en temps réel ou pour construire la carte des contraintes sur un horizon journalier. Une partie importante de cette thèse est consacrée à l'intégration de l'analyse de sécurité cyclique dans la réalisation du couplage production-réseau (introduction de la sécurité réseau dans la gestion prévisionnelle). Les résultats obtenus sur des données de planification issues du dispatching national montrent un gain de temps considérable acquit grâce à l'analyse cyclique. Elle se prête également bien aux analyses successives utilisées dans les optimisations du plan de tension en sécurité N et N-1.

Full textAbstract:
Aquesta tesi tracta sobre amplificació de potència d'alt rendiment de senyals variables en el temps; concretament, tracta sobre conversió de potència eficient (amb mínimes pèrdues) de tensions DC continues en senyals de tensió no constants.
Aquest tipus de conversió de potència està present en la majoria de dispositius electrònics d'ús quotidià, com ara telèfons mòbils i reproductors de música portàtils, així com també en dispositius d'alta potència com amplificadors d'àudio i estacions base de telefonia mòbil. Generalment l'energia està disponible en forma de tensió DC contínua (d'una bateria o d'una font d'alimentació). D'acord amb la informació a transmetre, aquesta energia s'ha de processar o transformar en un senyal variable en el temps de manera que, per exemple, es pugui convertir en àudio per un altaveu . La tendència de mercat és a reduir la mida i el pes dels dispositius electrònics i a oferir noves funcionalitats, incloent una llarga autonomia en dispositius alimentats per bateries. Millorar l'eficiència dels amplificadors de potència no només n'estendria l'autonomia, sinó que també permetria utilitzar dissipadors més petits i lleugers. Altres aplicacions com les d'alta potència o integrades també es beneficiarien de millores en l'eficiència dels amplificadors de potència.
Els dispositius electrònics de processament de potència més eficients són els amplificadors commutats. Aquests utilitzen components reactius (bàsicament bobines i condensadors) per dur a terme un processament de potència idealment sense pèrdues, així com dispositius actius (transistors) controlats com interruptors (o bé tancats o bé oberts), per tal de controlar aquest procés. Tot i que es poden assolir eficiències molt altes amb amplificadors commutats, la precisió de seguiment pot no ser gaire bona. Es pot millorar la precisió de seguiment senzillament incrementant la freqüència de commutació (la freqüència a la qual es fan commutar els interruptors), tot i que, com que es requereix una certa quantitat d'energia per
fer commutar cada interruptor (pèrdues de commutació), aquesta tècnica també deteriora l'eficiència de l'amplificador. Existeix doncs un comprimís entre la freqüència de commutació i la precisió de seguiment en els amplificadors commutats (compromís eficiència-distorsió).
Els amplificadors commutats habitualment es dissenyen per treballar a una freqüència de commutació alta comparada amb l'amplada de banda que han de seguir. Mentre que amb aquesta estratègia de disseny (i tecnologia actual) es poden dissenyar amplificadors per seguir senyals de l'ordre de kHz, si s'aplica per seguir senyals de l'ordre de MHz, els amplificadors haurien de treballar a freqüències de commutació massa altes, inviables des del punt de vista de les pèrdues de commutació.
Amb l'objectiu d'abordar el compromís entre distorsió i eficiència dels amplificadors commutats, aquesta tesi explora diferents tècniques per estendre l'amplada de banda relativa dels amplificadors commutats, és a dir, tècniques per reduir la relació entre la freqüència de commutació de l'amplificador i la seva amplada de banda de seguiment. Basant-se en una interpretació alternativa dels amplificadors commutats, com a procés de codificació i reconstrucció, les diferents tècniques d'extensió de banda que aquí s'exploren contemplen utilitzar modulacions alternatives, amplificació de potència multi-nivell, filtrat d'ordre elevat i polítiques de commutació millorades en els convertidors commutats.
La caracterització de les prestacions en termes de freqüència de commutació, error de seguiment i robustesa davant no idealitats (incloent compatibilitat electromagnètica i acoblament entre canals) apunta la idoneïtat de l'amplificació de potència multi-nivell basada en moduladors asíncrons per dissenys que treballin a freqüències de commutació relativament baixes, és a dir, a freqüències de commutació comparables a l'amplada de banda del senyal a seguir i amplificar.This thesis is about power amplification of time-varying signals; more precisely, it is about efficient power conversion, i.e. with minimum losses, of DC constant voltages into non-constant voltage signals. This kind of power conversion is quite common in power-management circuits and electronics in general. It is present in most everyday use electronic devices, including mobile phones, portable audio players and routers, as well as in high-power devices such as audio amplifiers and wireless base stations. In most electronic devices, whether portable or not, the energy is available as DC constant voltage (typically from a battery or a power supply). According to the information to transmit, this energy must be processed or transformed into a time-varying analogue signal so that, for instance, it can be directly converted into audio by a speaker or radiated by an antenna. The market trend is to reduce the size and weight of electronic devices whilst offering new or enhanced functionalities, including long autonomy in battery-powered devices (mainly portable). Improving the efficiency of power amplifiers not only extends the autonomy, but also allows using smaller and lighter heatsinks. Other applications such as high-power or embedded would also benefit from efficiency improvements of switching amplifiers. The most efficient power-processing electronic devices are switching amplifiers. Switching amplifiers use reactive components (mainly inductors and capacitors) to perform an ideally lossless power processing, and active devices (transistors) driven as switches, either ON or OFF, to control this process. Whilst very high efficiencies can be achieved with switching amplifiers, their tracking fidelity may not be very high. The tracking fidelity can be improved by simply increasing the switching frequency (i.e. the frequency at which the active devices are driven), although, provided that a certain amount of energy is required to switch the state of each active device (switching losses), this technique also degrades the efficiency of the amplifiers. Therefore, there exists a trade-off between switching frequency and tracking fidelity in switching amplifiers (efficiency-distortion trade-off). Switching amplifiers are typically designed using a high switching frequency compared to the amplifier's tracking bandwidth. Whilst this design strategy leads to feasible designs for kHz-bandwidth applications (using state-of-the-art technology), when applied to MHz-bandwidth applications, it leads to designs operating at very high switching frequencies, unfeasible with regard to switching losses. With the scope of addressing the efficiency-distortion trade-off of switching amplifiers, this thesis explores different techniques to extend the relative bandwidth of switching amplifiers, i.e. techniques to reduce the ratio of the amplifier's switching frequency to the amplifier's tracking bandwidth. Based on an alternative interpretation of switching amplifiers, as an encoding-reconstruction process, the different bandwidth extension techniques consider using alternative modulations, multi-level power amplification, high-order filtering and enhanced switching policies in the switching converter. The performance characterisations in terms of switching frequency, tracking error and robustness against non-idealities (including electromagnetic compatibility and crosstalk) points out the suitability of multi-level power amplification based on asynchronous modulators for designs operating at relatively low switching frequencies, i.e. at switching frequencies in the same range than the bandwidth of the signal to track and power amplify.

This study investigated the individual power of teachers as subordinates in elementary schools. It focused on the informal social structure in "good" elementary schools and the roles played by principals, teachers who held formal governance positions, itinerant teachers, and participants in the district's career ladder pilot program. Roles sampled were (1) providers of moral support, (2) sources of teaching expertise, (3) dispensers of procedural information, and (4) those able to "get things done" in the school. Peer and principal dependency data were also collected. Teachers and principals in five elementary schools in a single school district were sampled twice in a two year period. Findings were: (1) Although "good" principals received high total scores for providing resources to the faculty, there were instances when individual teachers scored as high or higher than the principal. (2) Faculty and principals depended on providers of moral support more than they depended on any of the traditionally power-producing roles. (3) Teachers depended on peers mostly for moral support, less for teaching expertise and "getting things done," and least for information. Teachers depended on the principal for moral support and information, less for "getting things done," and least for teaching expertise. (4) Full-time classroom teachers and specialists were most active in the social structure. Part-time teachers, itinerant teachers, and special services personnel, such as psychologists, speech/language pathologists, etc., were not key participants. Some full-time teachers, such as fine arts, physical education, and self-contained special education teachers were less active. (5) Teachers holding formal governance positions in the school established or gained influence while holding the formal positions, and they apparently did not lose influence the year after leaving the positions. Formal positions were held by full-time classroom teachers and only occasionally by a specialist. (6) Career ladder candidates or participants established or gained influence in the school's social structure during the career ladder process. Itinerant teachers and individuals who teach specialized curricula were more active in the career ladder program than they were in the school governance network.

Dissertação apresentada ao Programa de Pós-Graduação em Educação da Universidade do Extremo Sul Catarinense - UNESC, Estado de Santa Catarina, como um dos requisitos para obtenção do título de Mestre em Educação.La presente disertación posee como principal objetivo comprender los saberes y las prácticas que permearon la formación de las normalistas, en la Escola Normal Madre Teresa Michel – Criciúma (SC), en el período de 1958 hasta 1973. Como investigadora, bajo los ojos del presente, “cavé” el pasado de la primera Escuela Normal de 2º Ciclo de Criciúma, intentando construir, en un horizonte reciente, una imagen del significado de ese educandario para la sociedad de la época, bien como a la formación de las normalistas que en él estudiaron. Para tanto, “quité” el “suelo” del acervo escolar y de la Casa de la Cultura de Criciúma, “exploré” el banco de dados del Grupo de Búsqueda Historia y Memoria de la Educación – Grupehme – y entrevisté también mujeres, normalistas y profesoras, que frecuentaron ese educandario en el período en que se dedicó a este tipo de formación (1958-1973). Con eso, buscando encontrar memorias a las cuales contribuyeron para el esclarecimiento de la problemática en questión. Como norte para las análisis y problematización de las fuentes, me anclé en la teoría de Pierre Bourdieu, por medio de la apreciación de tres categorías principales: “capital cultural”, “habitus” y “poder simbólico”. Apoyada en los “fragmentos” encontrados en la “excavación”, observé que, en un contexto donde la exploración del carbón se convirtió el centro del desarrollo económico y de la población, la educación pasó a ganar destaque, en los discursos de la sociedad criciumense, la cual depositaba, en la escuela, las expectativas de aumento cultural de la ciudad. Así, este clamor no partía de todas las clases sociales, pero de la recién-formada clase media que, venida de grandes centros, creía que la reprodución de determinado capital cultural pudiese hacer que los/las jovenes, sus hijos y hijas, se convertieran los/las futuros/as responsables por la prosperidad intelectual y moral de la ciudad. Ese capital simbólico fue transmitido por la cultura escolar del Gimnasio Madre Teresa Michel inaugurado en 1956 por las Pequeñas Hermanas de la Divina Providencia – P.I.D.P., a fin de imprimir una manera de ser ciudadano y ciudadana, un habitus cultivado y naturalizado como lo ideal para la ciudad. Con la abertura de la Escuela Normal MTM, en 1958, tal status pasa a pertenecer, sobretodo, a las normalistas. Ellas, por su vez, buscaban, en las clases del educandario, los “ingredientes” necesarios para que pudiesem dar continuidad al desarrollo cultural de la ciudad, ya que serían ellas las responsables por transmitir el capital cultural indispensable a muchos niños, por medio de la actuación en escuelas de Criciúma y alrededores. Sin embargo, más que un habitus pedagógico, la Escuela Normal visaba, por medio de sus saberes y prácticas, una característica ideal de ser mujer, haciendo caminos que objetivasen mantener y reproduzir las actitudes y comportamientos deseados para las chicas por la sociedad de la época. Para concretizar tal hecho, las religiosas se utilizaban de recursos coactivos, visando mantener el capital simbólico dominante, instaurando puniciones para aquellas que intentaban burlar la cultura escolar instituída. Pero, había una lucha simbólica entre la cultura dominante y el comportamiento de algunas alumnas, que empleaban estratégias de resistencia para intentar legitimar su propia cultura, aprendida en otros campos y espacios.
A presente dissertação possui como principal objetivo compreender os saberes e as práticas que permearam a formação das normalistas, na Escola Normal Madre Teresa Michel – Criciúma (SC), no período de 1958 a 1973. Enquanto pesquisadora, sob os olhos do presente, “escavei” o passado da primeira Escola Normal de 2º Ciclo de Criciúma, tentando construir, num horizonte recente, uma imagem do significado desse educandário para a sociedade da época, bem como à formação das normalistas que nele estudaram. Para tanto, “revolvi” o “solo” do acervo escolar e da Casa da Cultura de Criciúma, “explorei” o banco de dados do Grupo de Pesquisa História e Memória da Educação – Grupehme – e entrevistei também mulheres, normalistas e professoras, que frequentaram esse educandário no período em que se dedicou a este tipo de formação (1958-1973). Com isso, buscando encontrar memórias as quais contribuíram para o esclarecimento da problemática em questão. Como norte para as análises e problematização das fontes, ancorei-me na teoria de Pierre Bourdieu, por meio da apreciação de três categorias principais: “capital cultural”, “habitus” e “poder simbólico”. Respaldada nos “fragmentos” encontrados na “escavação”, observei que, em um contexto onde a exploração do carvão tornava-se o centro do desenvolvimento econômico e populacional, a educação passou a ganhar destaque, nos discursos da sociedade criciumense, a qual depositava, na escola, as expectativas de ascensão cultural da cidade. Destarte, este clamor não partia de todas as classes sociais, porém da recém-formada classe média que, vinda de grandes centros, acreditava que a reprodução de determinado capital cultural pudesse fazer que os/as jovens, seus filhos e filhas, tornassem-se os/as futuros/as responsáveis pela prosperidade intelectual e moral da cidade.

No entanto, mais que um habitus pedagógico, a Escola Normal visava, por meio de seus saberes e práticas, uma feição ideal de ser mulher, perfazendo caminhos que objetivassem manter e reproduzir as atitudes e comportamentos desejados para as moças pela sociedade da época. Para concretizar tal feito, as religiosas utilizavam-se de recursos coercitivos, visando manter o capital simbólico dominante, instaurando punições para aquelas que tentavam burlar a cultura escolar instituída. Porém, havia uma luta simbólica entre a cultura dominante e o comportamento de algumas alunas, que empregavam estratégias de resistência para tentar legitimar sua própria cultura, aprendida em outros campos e espaços.

However, the lack of mathematical formalization and simulation of the method does not allow to analyse it on academical databases.This thesis focused on the understanding, the formalization and the reproduction of the method.

Acompanha: Temas ambientais no ensino da química: tratamento de água de abastecimento, estudo dos solos e fontes de energia: material do professorEsta pesquisa teve como objetivo elaborar um recurso educacional, contendo propostas de temas ambientais para o ensino da disciplina de Química do primeiro ano do Ensino Médio. A escolha dos temas ambientais se deu após análise dos três livros didáticos mais utilizados no universo das 30 maiores escolas estaduais de Curitiba e Região Metropolitana, o que levou à avaliação dos temas ambientais, segundo as seguintes categorias: temas conectados ao conteúdo programático; temas não conectados ao conteúdo programático e temas que apresentam conexão com outras disciplinas. Os dados da referida análise proporcionaram a elaboração de quatro tabelas, as quais elencam os temas ambientais apresentados nos livros volume um dos três autores analisados, a relação desses temas com o conteúdo programático do primeiro ano do ensino médio, os assuntos (água, energia, atmosfera, resíduos e materiais tóxicos e litosfera) que abrangem os temas apresentados e, por último, as sugestões interdisciplinares baseadas nos temas apresentados. A escolha dos temas ambientais utilizados na elaboração do recurso educacional foi baseada em dois aspectos: temas ambientais de grande relevância para a humanidade e/ou temas que aparecem com menor frequência nos livros didáticos analisados. Os temas selecionados e abordados no recurso educacional são: Tratamento de água para abastecimento, Contaminação radioativa do solo e Fontes de energia. As propostas de trabalho sugeridas no recurso educacional estão embasadas nos pilares da contextualização, temas geradores e interdisciplinaridade, em uma proposta que incentiva o educando a buscar o conhecimento a partir da pesquisa e do debate. O recurso educacional foi distribuído nas escolas que fazem parte do universo dessa pesquisa, acompanhado por um questionário a ser respondido pelo professor de Química que trabalha com o primeiro ano do Ensino Médio. O questionário objetivou verificar o grau de importância da aplicação de temas ambientais para o professor e com que frequência ele utiliza esses temas em suas aulas; a opinião do professor em relação aos temas ambientais tratados nos livros didáticos e a opinião com relação ao recurso educacional elaborado no que tange à conexão com o conteúdo programático para o primeiro ano do Ensino Médio. Também se buscou avaliar se os temas desenvolvidos estão adequados para os alunos do primeiro ano e se as sugestões de abordagem interdisciplinar são suficientes para a aplicação no processo ensino e aprendizagem. Após a análise das respostas dadas ao questionário, é possível inferir que os professores consideram importante a abordagem ambiental nas aulas de Química, mas utilizam pouco dessa abordagem. Os professores dividem-se na questão da adequação dos temas ambientais contidos no livro didático ao conteúdo programático da disciplina. Praticamente 90% dos professores responderam de forma positiva à aplicação do recurso educacional, declarando que as propostas estão condizentes e conectadas ao conteúdo programático do primeiro ano do Ensino Médio e que permitem uma ampla abordagem interdisciplinar.
This research aimed at developing an educational resource for Chemistry teaching, including proposals for the teaching of environmental issues for the first year of high school. The choice of the specific environmental issues occurred after analysis of the three textbooks most used among 30 public schools in Curitiba and its metropolitan region. The environmental issues were analyzed and classified under the following categories: themes connected to the curriculum; topics not connected to the program content and themes that have connection with other disciplines. From this analysis, data was organized in four tables which summarize the environmental themes presented in the first volume of each author’s book, and relate them to the first year of high school curriculum, to the main issues (water, energy, air, waste and toxic materials, and lithosphere) associated with the presented topics and; in addition, we propose interdisciplinary didactic suggestions based on the topics presented. The choice of environmental themes used in this educational didactic resource was based on two aspects: environmental issues of great importance for humanity and/or themes that appeared less frequently in the textbooks which were analyzed. The selected topics addressed in the educational didactic resource are: drinking water treatment, radioactive contamination of soil, and energy sources. The suggested educational resource is based in the pillars of contextualization, generating themes and interdisciplinarity, in a proposal that encourages the students to seek for knowledge based on research and debate. The educational resource was distributed in schools that took part in this research, accompanied by a questionnaire to be answered by the first year of high school chemistry professor. This questionnaire aimed at verifying: the importance of applying environmental issues in teacher’s opinion, and how often teachers use these themes in their classes; the teacher's opinion in relation to environmental issues discussed in textbooks; and teacher’s opinion regarding both the educational resource developed in this work and its connection to the curriculum of high-school first year. We also sought to assess whether the developed themes are suitable for first-year students and if the interdisciplinary approach proposed was suitable for application in the classroom. After analyzing the replies to the questionnaire, it can be inferred that teachers agree with the importance of an environmental approach in chemistry class, yet they do not often follow this approach. With respect to the adequacy of the environmental topics contained in the textbooks with the syllabus of the course, teachers have mixed opinions. Nearly 90% of teachers responded positively to the implementation of the proposed educational resource, declaring that is consistent and connected to the curriculum of the first year of high school, and that it allows a broad interdisciplinary approach.

Full textAbstract:
State officials, between 1882 and 1888, exchanged three million acres of Texas Panhandle property for construction of the monumental Capitol that continues to house Texas government today. The project and the land went to a Chicago syndicate led by men influential in business and politics. The red granite Austin State House is a recognizable symbol of Texas around the world. So too, the massive tract given in exchange for the building, what became the "fabulous" XIT Ranch, also has come to symbolize the height of the nineteenth century cattle industry. That eastern and foreign capital dominated the cattle business during this period is lesser known, absorbed by the mythology built around the Texas cattle-trail period - all but at an end in 1885. This study examines the interaction of Illinois Republicans and Texas Democrats in their actions and efforts to create what have become two of Texas's most treasured symbols.

Full textAbstract:
Le dommage d’irradiation dans la matière condensée est un phénomène important pour de nombreux domaines : les matériaux pour le nucléaire bien sûr, mais aussi l’électronique embarquée dans les satellites sujets aux rayonnements cosmiques, ou encore la matière vivante lors du traitement d’une tumeur par radiothérapie. Une connaissance précise de l’interaction entre la particule irradiante et le matériau cible est par conséquent fondamentale. L’interaction entre un projectile ionique et une cible peut être décrite par le biais du pouvoir d’arrêt. Il est défini comme étant le transfert d’énergie du projectile au matériau divisé par la profondeur d’implantation. La perte d’énergie d’un ion est induite majoritairement par les excitations électroniques de la cible. Le pouvoir d’arrêt électronique est alors la grandeur principale dans ce domaine. L’arrivée de la théorie de la fonctionnelle de la densité dépendante du temps (TDDFT) a permis d’améliorer largement la description de ce phénomène.Au cours de cette thèse, nous avons développé un code ab initio basé sur la TDDFT en temps réel (RT-TDDFT) dans les bases gaussiennes. Cette implémentation a des avantages considérables comme le traitement direct des électrons de cœurs, la rapidité de calculs des fonctionnelles hybrides et la flexibilité spatiale de la base. Avec notre code, nous avons vérifié la convergence du pouvoir d’arrêt vis-à-vis de la taille de la cible afin de tendre vers les matériaux cristallins. Nous avons analysé la dépendance du pouvoir d’arrêt en fonction du paramètre d’impact afin d’obtenir un pouvoir d’arrêt moyenné, correspondant aux conditions expérimentales. L’importance des excitations des électrons de cœurs dans l’irradiation ionique a été démontrée. Nous avons également étudié l’effet de la base gaussienne sur le pouvoir d’arrêt. Cette étude nous a permis de définir deux stratégies pour obtenir une bonne précision du pouvoir d’arrêt : l’extrapolation du pouvoir d’arrêt à partir des bases standards ou la génération de nouvelles bases.Finalement, nous avons calculé le pouvoir d’arrêt du lithium et de l’aluminium dans le cas de l’irradiation aux protons, aux antiprotons ainsi qu’aux particules alpha. Nous avons comparé nos résultats directement aux données expérimentales et aux données générées par le code empirique SRIM, largement utilisé par les expérimentateurs. Nous obtenons un bon accord avec SRIM lorsque celui-ci contient une base de données expérimentales suffisamment riche. De plus, nous avons observé l’effet de Barkas : le pouvoir d’arrêt des antiprotons est inférieur à celui des protons. Cet effet n’est pas reproduit dans les cas de théories plus simples telle que la théorie de la réponse linéaireIonic irradiation damage in condensed matter is central to many technological applications: materials in nuclear plants of course, but also electronics and solar panels in space that are subjected to the cosmic irradiation, living matter treated by radiotherapy to eliminate tumors, etc. For all these subjects, an accurate knowledge of the interaction between the irradiating projectile and the target is crucial. The interaction between the irradiating ion and the target material can be described by a stopping power, defined as the energy transfer from projectile to material per penetration distance. The most important ionic energy loss channels in the irradiation process are the electronic excitations. Therefore, the electronic stopping power is the central quantity in this field. With the advent of time-dependent density-functional theory (TDDFT), it is nowadays possible to provide a complete and realistic quantum-mechanical description of the phenomenon.In this thesis, we have developed a fully ab initio real-time TDDFT (RT-TDDFT) approach in the localized Gaussian basis. This implementation has several appealing advantages, such as the cheap account of core electrons, the ease of using the modern hybrid functionals, the flexibility of the basis set and overall low computational cost. With our tool, we explored the bulk limit, the validity of the projectile impact parameter averaging to obtain the experimental random electronic stopping power. We have proven the importance of core electron excitations in the ionic irradiations. A great care wasalso taken about the Gaussian basis set convergence: the extrapolation of the stopping power based on standard basis sets and the basis set generation scheme were proposed.Finally, we have computed the random electronic stopping power in lithium and aluminum targets for three types of projectiles: protons, antiprotons, and alpha-particles. We have compared our results directly to the experiment as well as to the empirical code SRIM, which is a widely-used database of stopping powers and a de facto standard for experimentalists. The agreement with SRIM is good when the SRIM database contains enough experimental points, whereas we show that the SRIM extrapolation can be hazardous when the underlying experimental data points are too few. Concerning the antiproton irradiation, our RT-TDDFT calculations show that the antiproton stopping power is lower than the proton one, which is in agreement with the general experimental observation (the so-called Barks effect). This effect is out of reach of simpler theories, such as the linear response approximation

Objetivo Geral - Propõe-se analisar o poder organizacional em Unidades de Informação sob a perspectiva política da Administração. Objetivos Específicos - Mensura a liderança em unidades de informação, identificando quaisos estilos de funcionamento de liderança organizacional (individualista, afiliativo,empreendedor ou um estilo de funcionamento de liderança burocrático). Mensura o poder da estrutura/cargo/autoridade, identificando quais as bases estruturais de poder (base estruturalde poder legítimo; de coerção; de recompensa; e base estrutural de poder de perícia). Mensura o conflito/retaliação, identificando quais os fatores que podem gerar o conflito/retaliação pelo não acesso ao poder organizacional (fator de conflito/retaliação afetivo e fator de conflito/retaliação conativo). Mensura a comunicação/informação entre membros das equipes de trabalho em Unidades de Informação, identificando a existência de interdependência detarefas e interdependência de resultados entre os membros das equipes. Metodologia - Trata-se de um estudo que apresenta resultados em mais de uma unidade de informação que são separados sem correlações entre si. Os contornos foram buscados emreferências tanto da área da Ciência da Informação quanto da Ciência da Administração para embasar os temas componentes da perspectiva política que tem o foco na análise do poderorganizacional em unidades de informação. Questionários para a análise do poder organizacional foram aplicados a uma amostra de 4 bibliotecarios-chefe das Bibliotecas Universitárias (BUs) do Sistema de Bibliotecas da Universidade Federal da Bahia(SIBI/UFBA) e a 4 coordenadores do Arquivo Público do Estado da Bahia (APEB), gerando resultados para cada uma delas. Estes resultados, que são apresentados e discutidos em separado, apontaram algumas fragilidades tanto no SIBI/UFBA quanto no APEB em relaçãoao poder organizacional. Conclusões - Conclui-se para as BUs do SIBI/UFBA que estas possuem um poder mais centrado no cargo, através do exercício da autoridade, e menos distribuído pelos membros das equipes de trabalho porque a análise dos elementos constituintes do poder organizacional indica um exercício de poder mais pautado na estrutura/cargo/autoridade do que nos princípios de liderança, embora haja um significativo potencial para a liderança, com grande potencial de conflito/retaliação afetivo (alto grau de insatisfação), mas isso não compromete o alcance de resultados por haver um alto grau de interdependência de tarefas e resultados pela existência de uma omunicação/informação transparente entre os membros das equipes de trabalho. Conclui-se para o APEB que este possui um poder mais centrado no cargo, através do exercício da autoridade, e menos distribuído pelos membros das equipes de trabalho. Nesta instituição, a análise dos elementos constituintes do poder organizacional indica um exercício de poder mais pautado na estrutura/cargo/autoridade do que nos princípios de liderança, com potenciais conflitos/retaliação de cunho afetivo (insatisfações latentes) e baixo grau de alcance de tarefas e resultados pela existência de uma comunicação restrita da informação entre membros das equipes de trabalho. Estas fragilidades, mais do que pontos fracos, são oportunidades de aprimoramento da gestão das unidades de informação estudadas, e é isso que o presente trabalho demonstra, ou seja, que ações de melhoria na liderança, na estrutura de poder, no conflito organizacional e na comunicação/informação entre os membros das equipes de trabalho podem, de fato, conduzir a uma maior eficiência na gestão.
ABSTRACT General Objective - The overall objective of this thesis is to analyze the organizational power in Information Units under the political perspective of Management Science. Specific Objectives - The following specific objectives we have: a) Measure the leadership in Information Units, identifying the organization's operating styles (individualistic, affiliative, entrepreneur or a bureaucratic leadership style of functioning); b) Measure the power of structure /function / authority, identifying the structural bases of power (structural basis of legitimate power, coercion, reward, and structural basis of skill power); c) Measure the conflict / retaliation, identifying the factors that may cause the conflict / retaliation for no access to organizational power (affective conflict factor or conative conflict factor) and d) Measuring the communication / information among members of work teams in Information Units, identifying the existence of interdependence in the tasks and interdependence of results between team members. Methodology - This research is a multiple case study to present results in more than one unit of information, results that are separated without correlations with each other. The contours were sought in Information Science and Management Science references to support the policy perspective component themes that has the focus on the analysis of organizational power in information units.Questionnaires for the analysis of organizational power were applied to 4 librarians chief of the University Libraries (BUs) of the Library System of the Federal University of Bahia (SIBI / UFBA) and to 4 coordinators of the Public Archives of the State of Bahia (APEB), generating results for each of them. These results, which are presented and discussed separately, pointed out some weaknesses in the SIBI / UFBA and APEB in relation to organizational power. Conclusions - It is concluded that the University Libraries of the Federal University of Bahia Library System (SIBI/UFBA) have an organizational power more focused on the head, through the exercise of authority, and less distributed by members of work teams because power analysis organizational indicates a exercise of power more guided to the structure / function / authority than in the principles of leadership, although SIBI/UFBA has significant potential for leadership, with great potential for conflicts of affective nature (high degree of dissatisfaction), but it does not compromise the achievement of results, because there is in the SIBI/UFBA a high degree of interdependence in the execution of operations and in achieving results because there is a transparent communication and information among members of work teams. It concludes that the Public Archives of the State of Bahia (APEB) has a more focused organizational power in head, through the exercise of authority, and less distributed by members of work teams because the analysis of organizational power indicates the power of exercise more founded on the structure/function/ authority than in the principles of leadership, with potential conflicts of affective nature (latent dissatisfaction) and low degree of execution of operations and in achieving results, because there is in the APEB a restricted communication of information between members of teams work. These weaknesses, rather than weaknesses are opportunities for improvement of the management of these information units, and that's what this paper demonstrates, that improvement actions in the lead, actions to improve the distribution of positions in the hierarchical structure, improvement actions to resolve organizational conflicts and actions to improve the communication and information among members of work teams can actually lead to greater efficiency in working with the information.

Full textAbstract:
Ce travail s'inscrit dans l'analyse économique des architectures de marché électrique. Il s'appuie sur un cadre d'analyse modulaire permettant de séparer les problèmes du market design en modules distincts. Il se concentre sur le design du temps réel ayant un rôle clé pour l'électricité. Un modèle d'équilibre à deux étapes a permis d'analyser les deux variantes de design du temps réel : le marché et le mécanisme (utilisant de pénalités). Les simulations numériques ont montré que le design du temps réel n'est pas neutre vis-à-vis de la séquence des marchés d'énergie et de la dynamique concurrentielle. Les designs s'écartant du « marché » provoquent des distorsions, des inefficacités et peuvent créer des barrières à l'entrée. L'ampleur des distorsions est déterminée par la fermeture des marchés forward (gate closure). Cette modélisation a permis aussi de montrer le rôle fondamental de l'intégration entre deux zones en temps réel et l'importance d'une harmonisation adéquate des designs.

Full textAbstract:
Le mixe énergétique du futur réseau électrique doit intégrer une grande quantité de source renouvelable intermittentes (RES). L’intermittence naturelle de ces sources sera,dans un premier moment, négligeable vis-à-vis de la stabilité du réseau électrique. Par contre,pour une large pénétration de RES, cette intermittence doit être intégrée à l'étude de la stabilité du réseau électrique. Pour une grande pénétration de RES à l'échelle européenne, un grand système de stockage d'énergie doit être mis en place. C'est déjà le cas aujourd'hui où les stations de transfert d'énergie par pompage(STEP) sont déjà utilisées. En effet, les STEP sont le moyen de stockage plus fiable et mature pour le stockage en haut puissance. Cependant,elles sont utilisées à ce jour, plutôt dans un cycle journalier et hebdomadaire d'équilibrage. La plupart des usines fonctionne de façon binaire(soit on, soit off) et ne participe pas à l'équilibrage du réseau électrique.Les nouvelles technologies envisagent de nouvelles utilisations pour les STEP. Les STEP à vitesse variable (Variable Speed PSP - de l'anglais Variable Speed Pumped Storage Plant)sont prévues de d'être utilisées en temps réel pour l'équilibrage du réseau électrique. L'objective de ce projet de ce projet est d'étudier les contributions de la STEP à vitesse variable à l'équilibrage du réseau électrique. Du point de vue du réseau, la STEP à vitesse variable est composée de deux systèmes en cascade séparés par les échelles de temps différentes. Le système peut réagir en 100ms avec la puissance nominale de la machine mais pour un temps limité (entre 5- 10s); le deuxième étage est le système hydraulique qui réagit moins vite (après 15s)mais qui peut tenir sa puissance pendant un longtemps (plusieurs heures). Ces différentes échelles de temps sont très importantes pour l'équilibrage du réseau électrique. Elles permettent que la STEP à vitesse variable soit utilisée pour différents problèmes d'équilibrage, mais comment l'utilisée reste encore un problème ouvert. Parmi d'autres,ce projet a comme objective répondre aux questions suivantes:Serait-il possible d'utiliser la STEP à vitesse variable pour l'équilibrage du réseau électrique à courant alternatif (AC) et/ou continu (DC)? Comment combiner, de façon intelligente, les réseaux continus à haute tension (HVDC - de l'anglais High Voltage Direct Current) et STEP à vitesse variable?Combinaison optimale de réaction rapide et lente pour équilibrer un réseau hybride AC et DC? La STEP à vitesse variable est-il un bon outil dynamique de stockage pour augmenter la capacité du réseau HVDC? Comment intégrer le contrôle d'une ligne HVDC et ce d'une STEP à vitesse variable?La STEP à vitesse variable peut atténuer les oscillations du réseau?The future energy mix used toproduce electricity will include large shares ofrenewable energy sources (renewables). Theintrinsic time varying nature of these sourceswill be in the first a hinder to power systems'stability, but as their share will increase theypower of the machine but only for a limited time(typically 5 – 10 seconds); the second stage isthe hydraulic system that reacts slower (afterapprox. 15 seconds) but has a lot of energystored.These different time scales can be of uppermostUniversité Paris-SaclayEspace Technologique / Immeuble DiscoveryRoute de l’Orme aux Merisiers RD 128 / 91190 Saint-Aubin, Francemust be explicitly taken into account in thefuture when stabilizing the network. Forconstant use of renewables, in a Europe-widemanner, large storage will be capital. This isalready partially the case today, where pumpedwater storage is largely used. In fact waterstorage still is the most reliable and efficientstorage system for large amounts of power. Buttoday this is still mainly dedicated to findnight/day or weekly equilibrium of productionand consumption. These store plants are ratherplanned for an on/off utilization and do notparticipate on ancillary services (dynamicparticipation on the short term equilibrium of aninterconnection of systems or regions).New technologies allow envisaging new usesfor large storage systems. Variable SpeedPumped Storage Plants (Variable Speed PSP)are now expected to be used in real time toprovide ancillary services, effectivelyparticipating in the stabilization of powersystems. The objectives of this work are to studysome of these possibilities. It will look atdifferent aspects of stabilization: Variable SpeedPSP can be seen from the outside like a twostage systems in cascade that reacts with timeconstants that are one order of magnitude apart.The system can react within 100ms with ratedimportance when considering system's stability.They allow Variable Speed PSP to be used as thecontrol input for different stabilizationproblems, but how to do it is still an openproblem. Today these stations are only used asstandard storage, allowing the match ofproduction and consumption within a region ornetwork. The objective now is to study their useto further applications, and in particular, to studythe possibility of using them as one of the keycomponents of the future Multi-terminal HVDCnetworks. Several questions are open, this workaims to answer part of them:Is it possible to use Variable Speed PSP forancillary services (transient stability forexample) in AC and/or HVCD networks?How to combine in an intelligent way HVDCand Variable Speed PSP?Optimum combination of fast and slow reactionin order to stabilize a power grid that combinesDC and AC?Is Variable Speed PSP a good way to increasethe capability of HVDC by adding a verydynamic storage element?How to merge the control of the HVDC line andthe Variable Speed?Can this setup help to damp oscillations in thegrid?
