The purpose of this study was to determine how deans of colleges within the state-supported, four-year universities in Texas use accounting information to allocate and control resources dedicated to faculty salaries, departmental operating expense, and instructional administration expense. Conclusions: 1. Communication is better between deans and financial officers at small universities than at large universities. 2. The relationship between line and staff appears to be misunderstood at several large universities. 3. Ten per cent of the deans at large universities and 2 per cent at small universities do not receive financial reports. 4. The financial reports, if comparative, usually compare year-to-date actual amounts with annual planned amounts. 5. Some of the deans keep their own set of financial records. 6. Deans are cost conscious and aware of the state formulas used in the state appropriation. 7. Many deans are frustrated and angry. 8. Most deans participate extensively in budgeting faculty salaries and departmental operating expense but 20 per cent do not participate in planning of instructional administration expense.

Dans l'industrie sidérurgique, les fours de réchauffage sont les plus grands consommateurs d'énergie après les hauts fourneaux. Réduire leur consommation énergétique est donc la préoccupation majeure de la commande des fours. Dans un four de réchauffage, des brames d'acier sont chauffées en traversant successivement plusieurs zones, de la température ambiante à un profil de température homogène de 1250 °C en sortie du four, avant d’être laminées dans les laminoirs à chaud. La température de brames est contrôlée par une structure de commande hiérarchisée à deux niveaux (niveau 1 et 2).L'objectif de ces travaux est d'améliorer la performance du chauffage et donc de réduire la consommation énergétique du four via une stratégie de commande prédictive distribuée hiérarchisée sur les deux niveaux de commande. Une approche de commande prédictive distribuée est tout d’abord développée pour le niveau 1 afin de suivre les consignes de température de zone, prenant en compte les couplages entre les zones et induisant une moindre complexité d’implantation par rapport à une approche centralisée. L’implantation industrielle a permis une amélioration significative de la précision du suivi de température et une réduction de la consommation d'énergie de 3%. Une deuxième étape propose l’élaboration de la commande prédictive hiérarchisée du niveau 2 afin, à partir de la consigne de température de brame, de déterminer les consignes de température optimales des zones en se fondant sur un modèle de transfert thermique du four. Les résultats de simulation, comparés aux données industrielles, montrent une réduction de la consommation énergétique de 5% et une meilleure qualité de chauffage des brames. L’approche précédente est enfin étendue pour prendre en compte et optimiser le cadencement des brames afin d’augmenter la productivité du four. La simulation montre une augmentation potentielle de productivité du four de 15 tonnes par heure tout en améliorant la qualité de chauffage des brames. / In steel industry, reheating furnaces are the biggest energy consumers after blast furnaces. As a result, reduction of energy consumption is the major concern of furnace control. In a walking-beam slab reheating furnace, steel slabs are heated by moving through successive zones from ambient temperature to a homogenous temperature profile of 1250°C at the furnace exit, to be rolled subsequently in the hot rolling mills. Temperature of slabs is controlled mainly by a two-level hierarchical structure, so called level 1 and level 2.The aim of this thesis is to improve the heating performance and consequently to reduce the energy consumption of the furnace by using hierarchical distributed model predictive control (MPC) strategy for both levels. In a first step, distributed model predictive controllers are developed for the level 1 in order to track zone temperature set-points. The distributed feature of the control law enables to consider coupling effects between zones while reducing the computation complexity compared to a complete centralized approach. The industrial results showed significant improvement on temperature tracking accuracy and an energy consumption reduction of 3%. In a second step, the hierarchical MPC is constructed for the level 2 in order to determine the optimal zones temperature setpoint from the slab temperature setpoint, based on a numerical heat transfer model of the furnace. The simulation results obtained with this strategy compared against industrial data show an energy consumption reduction of 5% and a better heating quality. The previous structure is finally extended to take into account and optimize the scheduling of the slabs within the MPC level 2 in order to increase productivity of the considered furnace. The simulation shows a potential increase of productivity of the furnace of 15 tons per hour while improving the slab heating quality.

The manner in which socioeconomic forces direct environmentally unsustainable behaviour is largely unseen and unappreciated. North American cultural beliefs, norms and values reinforce the economic system and constitute significant barriers to large-scale societal ecological behaviour change. Overlooked in the degrowth literature, even by researchers who have examined the importance of socioeconomic barriers (materialism and consumption), is the role occupation plays in dictating the ecological footprint and forming our socioeconomic identities. We have gained some understanding of the motivation of those individuals who have chosen to pursue a low-carbon lifestyle, but are lacking information about those who go one step further and adopt a low-carbon livelihood. Fifteen individuals who successfully adopted low-carbon livelihoods were interviewed to examine socioeconomic barriers they may have experienced and learn how those challenges were met. To assume a low-carbon livelihood at present is likely to require forming a new social status identity, adopting new metrics for judging oneself, and creating a new social network supportive of that identity and its values. A four-quadrant framework was used to examine the systemic nature of emergent themes regarding socioeconomic barriers and how those were overcome. Themes that emerged revealed many similarities to individuals committed to a low-carbon lifestyle with some critical differences in terms of both inhibiting and enabling factors. A core finding was that motivational and personality characteristics of the low-carbon livelihood individuals mimic the attributes of moral exemplars that drive a deep sense of ethical obligation to create a pro- social occupation that can function in a low-carbon manner. Clear values, coupled with a strong sense of personal responsibility, overpowered the socioeconomic barriers participants encountered. Implications regarding interventions for fostering the adoption of low-carbon livelihoods and fortifying the Degrowth movement are examined. / Graduate

It is possible to identify immediately the ethical-religious nature of the Biblical text of the first century and the political-educational character of the report based on the contemporary education s worldview. At a first moment, the research sets the examination of the theoretical principles of the genders of discourse, the conditions of production, the ethos, and the interdiscursivity. After that, both discourses are examined under those principles so that, at last, it is possible to verify and confirm the interdiscursivity between these discourses about the question of learning to be. / Esta tese tem como objetivo principal pesquisar a interdiscursividade entre o Sermão do Monte, do Evangelho de Mateus, e os Quatro Pilares da Educação do Relatório da Comissão Internacional sobre a Educação para o Século XXI apresentado à UNESCO. De imediato se identifica o caráter ético-religioso do texto bíblico do primeiro século, enquanto que o texto do relatório revela-se político-educacional, alicerçado na cosmovisão de educação contemporânea. A pesquisa se detém num primeiro momento no exame do referencial teórico dos gêneros discursivos, das condições de produção, do ethos e da interdiscursividade, aplicados, em seguida, a cada um dos textos citados para, ao final, buscar-se e confirmar a concorrência da interdiscursividade entre esses discursos, quanto ao aprender a ser.

Orientador: Nobuo Oki / Banca: Saulo Finco / Banca: Cláudio Kitano / Resumo: Nesse trabalho, propõe-se o projeto e implementação de um sintetizador de sinais ortogonais utilizando técnicas de circuito integrado e processo CMOS. O circuito do sintetizador baseia-se em um modelo matemático que utiliza multiplicadores e integradores analógicos, para geração de bases de funções ortogonais, tais como os polinômios de Legendre, as funções de base coseno e seno, a smoothed-cosine basis e os polinômios de Hermite. Funções ortogonais são bastante empregadas em processamento de sinais, e a implementação deste método matemático é capaz de gerar vários tipos de funções em um mesmo circuito integrado. O projeto proposto utiliza blocos analógicos funcionais para implementar o sintetizador. Os blocos que compõem o sintetizador foram projetados utilizando circuitos diferenciais, processamento em modo de corrente e técnicas de low-voltage. Algumas topologias utilizadas estão descritas na literatura, sendo que algumas foram adaptadas e mesmo modificadas, como no caso do multiplicador de corrente. Outras tiveram que ser propostas. As simulações e os resultados experimentais mostraram que o sintetizador é capaz de gerar funções ortogonais com amplitude e distorções satisfatórias. O sintetizador pode ser alimentado em 3V, tal qual foi projetado, tem faixa de entrada de ±20 μA e apresenta DHT (distorção harmônica total) inferior a 4% no quinto e último estágio em cascata. / Abstract: In this work, a design and implementation of a synthesizer of orthogonal signals using CMOS technology and design technique for integrated circuits is proposed. The synthesizer circuit used analog multipliers and integrators for produce orthogonal functions such as Legendre polynomials, cosine and sine basis of functions, smoothed-cosine basis and Hermite polynomials. Orthogonal functions can be employed in signal processing and the implementation proposed can generate several kinds of functions in the same integrated circuit. In the synthesizer design building blocks was employed. The synthesizer's blocks were design using differential circuits, low-voltage and current-mode techniques. Some topologies from papers were adapted or modified, as in the case of the current multiplier. Other topologies had to be proposed. The simulation and experimental results have shown that the synthesizer is able to produce orthogonal functions with satisfactory quality in distortions and amplitude. The synthesizer has a 3V supply voltage, a input current range of ±20 μA and it presents less than 4% of THD (Total Harmonic Distortion) in the last output in cascade. / Mestre

Este trabalho investiga a influência dos efeitos da mistura de quatro ondas (FWM -. Four- Wave Mixing) durante o estabelecimento de caminhos ópticos em uma rede GMPLS/DWDM (Generalized MultiProtocol Label Switching/Dense Wavelength Division Multiplexing). Para minimizar seus impactos e assim reduzir o bloqueio total da rede, são propostas estratégias por meio de extensões ao RSVP-TE (Resource Reservation Protocol-Traffic Engineering). A partir de uma plataforma de simulação que emula e integra a camada óptica e o Plano de Controle da arquitetura GMPLS, a solução proposta é validada. Os vários métodos de alocação de comprimentos de onda são avaliados e as contribuições na redução dos sinais interferentes quantificadas. Para minimizar o bloqueio na rede, uma nova classe de métodos de alocação, classificados como híbridos, é definida e seu desempenho é avaliado. O bloqueio da rede em função da variação de parâmetros que reforçam a eficiência da FWM, tais como a quantidade e espaçamento entre canais, é observado, confirmando a necessidade de métodos de alocação especialistas para gerenciamento do QoS (Quality of Service) óptico em cada caminho a ser estabelecido. Os resultados obtidos comprovam a eficiência da solução proposta e evidenciam a necessidade de um Plano de Controle GMPLS com acurada visibilidade das restrições da camada física, tanto os efeitos estáticos quanto às degradações associadas ao comportamento dinâmico da rede. / This work investigates the effects of the Four-Wave Mixing (FWM) during the lightpaths establishment in a GMPLS/DWDM (Generalized Multiprotocol Label Switching / Dense Wavelength Division Multiplexing) network. In order to minimize their impacts and thus reduce network blocking, strategies based on RSVP-TE (Resource Reservation Protocol- Traffic Engineering) extensions are proposed. The proposed solution is validated using a simulation platform that integrates and emulates the optical layer and the GMPLS Control Plane. The various wavelength allocation methods are evaluated and their contributions on the reduction of interfering signals are quantified. In order to minimize the network blocking, a new class of allocation methods (classified as hybrids) is defined and its performance is evaluated. The network blocking caused by the parameters that enhance the FWM efficiency, such as the number and spacing between channels, is also observed, confirming the need of specialized wavelength allocation methods for managing the optical QoS for each lightpath. The results obtained ascertain that the proposed solution is efficient and demonstrate the need for a GMPLS Control Plane endowed with an accurate visibility of the restrictions in the physical layer, concerning both static and dynamic effects.

In recent years, tightening budgets have forced school districts to find new ways to save money. One way that has become increasingly popular is to shorten the traditional five-day school week to only four-days a week. This change is budget friendly and may act through efficiency wage theory as a recruitment tool for better teachers. Despite the increasing prevalence of districts running on four-day weeks, many of the effects of the shorter week on students are still unclear. Utilizing district-level panel data from the Colorado Department of Education, Study One took a difference-in-differences approach to determine the effect of the implementation of the four-day week on various delinquency measures, including suspensions, expulsions, and juvenile arrest rates. No significant results were found with robust standard errors, but trends suggested that juvenile crime may be increasing while school related incidents may be decreasing in areas with four-day school weeks. To offset these trends, this paper also proposes a second study aimed at investigating the effects of different types of fifth-day programs on adolescent well-being, academic achievement, and problem behaviors. Schools using the four-day week that agree to participate will be randomly assigned to receive either a career-prep program, an academic program, a recreational program, a social skills/mentoring program, or no program at all. Students (N=XXX) will fill out a survey at the beginning and at the end of the program or school year, reporting their subjective well-being and recent engagement in problem behaviors. It is expected that students who participate in the social skills/mentoring program will show the highest levels of well-being and little engagement in problem behaviors. This study will help to advance the research on after school programming, particularly in rural environments.

Récemment, les constructeurs automobiles se sont intéressés au développement des catalyseurs appelés quatre voies, destinés à diminuer simultanément les émissions polluantes des moteurs diesels par l'intermédiaire d'un seul monolithe catalytique. Dans cet objectif, plusieurs études ont montré que la capacité de stockage des NOx de ces catalyseurs est inhibée par la présence de suies. Les travaux présentés dans ce manuscrit s'inscrivent dans la compréhension des phénomènes en cause. Les résultats obtenus montrent que la présence de noir de carbone entraîne une diminution de la stabilité des nitrates adsorbés par les systèmes catalytiques étudiés et, ainsi, de leur capacité de stockage des NOx. Ce phénomène a été attribué à une réduction des espèces nitrates adsorbées à la surface des matériaux par les particules de carbone adjacentes. La présence d'une particule Pt à proximité d'un site de carbone favorise la formation de complexes oxygénés de surface, limitant l'effet réducteur du carbone envers les nitrates adsorbés. La perte de capacité d'adsorption des NOx des catalyseurs étudiés, observée lors de leur mise en contact avec du noir de carbone, s'est révélée irréversible à l'issue de l'oxydation du carbone. La caractérisation des matériaux par microscopie à transmission (MET) a révélé une modification importante de la structure des matériaux. Un frittage des particules de platine et une modification de la structure des particules de Ba entraînent en effet la perte irréversible de l'activité des matériaux vis-à-vis de l'adsorption des NOx. / Recently, car manufacturers have developed "4 way" catalytic converters in order to couple hydrocarbon and CO oxidation, soot combustion and DeNOx fonctions on a single monolith. Several studies showed that the NOx storage capacity of NSR catalysts is reduced in the presence of soot. The aim of this work is to investigate the effect of carbon­ NSR catalyst contact on the ability of the catalyst to store NOx. The results show that the presence of carbon black in the catalytic bed involves a decrease of adsorbed nitrates stability and of the NOx storage capacity of materials. It is proposed that the proximity of the carbon particles and NOx adsorbents sites leads to a reduction of the stored nitrates species. The decrease of the NOx storage capacity is Jess important when platinum is present in the catalytic material composition. In agreement with previous studies on the catalytic combustion of soot, it is suggested that platinum increases the number of surface-oxygen complexes -C(O), which thus led to a decrease in the reducing character of carbon. Our study reveals that the deactivation of the NOx storage activity due to carbon-catalyst contact is an irreversible phenomena, and thus even when all carbon is burnt. Characterization of materials by transmission electron microscopy (TEM) showed that sintering of the platinum particles and a structural modification of the barium particles occurs after that the catalysts was in contact with carbon. The decrease in the NOx storage activity of the materials is then assigned to a lesser proximity of the oxidizing sites (Pt) and adsorption sites (Al or Ba).
