O objetivo deste trabalho é analisar a contribuição dos conteúdos programáticos dos cursos de Administração para a implementação da cultura da excelência em empresas vencedoras do prêmio Qualidade RS. Este prêmio reconhece as organizações que mais se destacam na busca pela melhoria contínua do seu sistema de gestão, com base no Modelo de Excelência da Gestão (MEG). O que se propõe é a construção de um projeto político-pedagógico que esteja baseado no MEG, visando à formação de um profissional qualificado para empresas “classe mundial”. Para tanto, foram elaborados questionários, com base nos critérios e itens do MEG, para empresários e coordenadores de cursos. Foram obtidos resultados que levaram a uma nova proposta de pontuação para o método de avaliação do modelo, alterando-se os pesos relativos dos critérios. Por fim, foi proposto um novo modelo de currículo para os cursos de graduação em Administração, que permita que o aluno desenvolva a capacidade de compreensão da cultura da excelência, fundamental para o alcance da Classe Mundial nas organizações.

O depósito cupro-aurífero Visconde está localizado na Província Mineral de Carajás, a cerca de 15 km a leste do depósito congênere de classe mundial Sossego. Encontra-se em uma zona de cisalhamento de direção WNW-ESE, que marca o contato das rochas metavulcanossedimentares da Bacia Carajás com o embasamento. Nessa zona ocorrem outros depósitos hidrotermais cupro-auríferos com características similares (Alvo 118, Cristalino, Jatobá, Bacaba, Bacuri, Castanha), que têm sido enquadrados na classe IOCG (Iron Oxide Copper-Gold), embora muitas dúvidas ainda existam quanto a sua gênese, principalmente no que diz respeito à idade da mineralização e fontes dos fluidos, ligantes e metais. O depósito Visconde está hospedado em rochas arqueanas variavelmente cisalhadas e alteradas hidrotermalmente, as principais sendo metavulcânicas félsicas (2968 ± 15 Ma), o Granito Serra Dourada (2860 ± 22 Ma) e gabros/dioritos. Elas registram diversos tipos de alteração hidrotermal com forte controle estrutural, destacando-se as alterações sódica (albita + escapolita) e sódico-cálcica (albita + actinolita ± turmalina ± quartzo ± magnetita ± escapolita), mais precoces, que promoveram a substituição ubíqua de minerais primários das rochas e a disseminação de calcopirita, pirita, molibdenita e pentlandita. Dados isotópicos de oxigênio e hidrogênio de minerais representativos desses tipos de alteração mostram que os fluidos hidrotermais foram quentes (410 – 355°C) e ricos em 18O (δ18OH2O= +4,2 a 9,4‰). Sobreveio a alteração potássica, caracterizada pela intensa biotitização das rochas, a qual ocorreu concomitantemente ao desenvolvimento de foliação milonítica, notavelmente desenhada pela orientação de palhetas de biotita, que precipitaram de fluidos com assinatura isotópica de oxigênio similar à dos estágios anteriores (δ18OH2O entre +4,8 e +7,2‰, a 355°C). Microclina e alanita são outras fases características desse estágio, além da calcopirita precipitada nos planos da foliação. A temperaturas mais baixas (230 ± 11°C), fluidos empobrecidos em 18O (δ18OH2O = -1,3 a +3,7‰) geraram associações de minerais cálcico-magnesianos (albita + epidoto + clorita ± calcita ± actinolita) que são contemporâneas à mineralização. Valores de δ18DH2O e δOH2O indicam que os fluidos hidrotermais foram inicialmente formados por águas metamórficas e formacionais, a que se misturou alguma água de fonte magmática. Nos estágios tardios, houve considerável influxo de águas superficiais. Diluição e queda da temperatura provocaram a precipitação de abundantes sulfetos (calcopirita ± bornita ± calcocita ± digenita), os quais se concentraram principalmente em brechas tectônicas - os principais corpos de minério - que chegam a conter até cerca de 60% de sulfetos. Veios constituídos por minerais sódico-cálcicos também apresentam comumente sulfetos. A associação de minerais de minério e ganga indica uma assinatura de Cu-Au- Fe-Ni-ETRL-B-P para a mineralização. Os valores de δ34S (-1,2 a +3,4‰) de sulfetos sugerem enxofre de origem magmática (proveniente da exsolução de magmas ou da dissolução de sulfetos das rochas ígneas pré-existentes) e precipitação em condições levemente oxidantes. Datação do minério por lixiviação e dissolução total de Pb em calcopirita forneceu idades de 2736 ± 100 Ma e 2729 ± 150 Ma, que indicam ser a mineralização neoarqueana e, a despeito dos altos erros, permite descartar um evento mineralizador paleoproterozoico. A idade de 2746 ± 7 Ma (MSDW=4,9; evaporação de Pb em zircão), obtida em um corpo granítico não mineralizado (correlacionado à Suíte Planalto) que ocorre na área do depósito, foi interpretada como a idade mínima da mineralização. Assim, a formação do depósito Visconde teria relação com o evento transpressivo ocorrido entre 2,76 e 2,74 Ga, reponsável pela inversão da Bacia Carajás e pela geração de magmatismo granítico nos domínios Carajás e de Transição. Esse evento teria desencadeado reações de devolatilização em rochas do Supergrupo Itacaiúnas, ou mesmo, provocado a expulsão de fluidos conatos salinos aprisionados em seus intertícios. Esses fluidos teriam migrado pelas zonas de cisalhamento e reagido com as rochas (da bacia e do embasamento) pelas quais se movimentaram durante a fase dúctil. As concentrações subeconômicas do depósito Visconde devem ser resultado da ausência de grandes estruturas que teriam favorecido maior influxo de fluidos superficiais, tal como ocorreu na formação dos depósitos Sossego e Alvo 118.

The corporate world is increasingly competitive, and companies need to go deep into the routines and work them in order to understand them fully. The market is demanding more than simple improvements that bring advances - of small or great expression; however, in a longer term it will no longer meet the ideology of the market. Companies aimed at the world class must focus on projects that will continually bring returns to the company. As previously mentioned, understanding the processes in minute details is of paramount importance, as this knowledge can be acquired by analyzing the decisions that are necessary during the process. Once the complexity increases, the quantity and difficulty of the criteria that influence them grow accordingly. At this time, methods and tools that assist decisionmaking processes can be used as, besides being able to provide the best decision methods of MCDA (Multiple Criteria Decision Aid), they provide clear and assertive understanding of the whole decision process. In developing this study, we sought to explore the AHP (Analytic Hierarchy Process) method (a MCDA method) in the choice of access service, featured by the support service used to reach and be the basis of repairs in places of difficult access. This work proposes a study of the quantitative modeling approach in a real routine activity for a Brazilian petrochemical company. Decision-making processes are explored when we seek to analyze not only the decision makers but also what directly influences them on the use of the AIJ method. Once this is achieved, the understanding of decision-making is substantiated

The Vancouver International Airport (YVR) is the second busiest airport in Canada. YVR is located on Sea Island in the Fraser River Estuary - a world-class wintering and staging area for hundreds of thousands of migratory birds. The Fraser Delta supports Canada’s largest wintering populations of waterfowl, shorebirds, and raptors. The large number of aircraft movements and the presence of many birds near YVR pose a wide range of considerable aviation safety hazards. Until the late 1980s when a full-time Wildlife Control Program (WCP) was initiated, YVR had the highest number of bird strikes of any Canadian commercial airport. Although the risks of bird strikes associated with the operation of YVR are generally well known by airport managers, and a number of risk assessments have been conducted associated with the Sea Island Conservation Area, no quantitative assessment of risks of bird strikes has been conducted for airport operations at YVR. Because the goal of all airports is to operate safely, an airport wildlife management program strives to reduce the risk of bird strikes. A risk assessment establishes the current risk of strikes, which can be used as a benchmark to focus wildlife control activities and to assess the effectiveness of the program in reducing bird strike risks. A quantitative risk assessment also documents the process and information used in assessing risk and allows the assessment to be repeated in the future in order to measure the change in risk over time in an objective and comparative manner. This study was undertaken to comply with new Canadian legislation expected to take effect in 2006 requiring airports in Canada to conduct a risk assessment and develop a wildlife management plan. Although YVR has had a management plan for many years, it took this opportunity to update the plan and conduct a risk assessment.

While the use of distributed intelligence has been incrementally spreading in the design of a great number of intelligent systems, the field of Artificial Intelligence in Real Time Strategy games has remained mostly a centralized environment. Despite turn-based games have attained AIs of world-class level, the fast paced nature of RTS games has proven to be a significant obstacle to the quality of its AIs. Chapter 1 introduces RTS games describing their characteristics, mechanics and elements. Chapter 2 introduces Multi-Agent Systems and the use of the Beliefs-Desires-Intentions abstraction, analysing the possibilities given by self-computing properties. In Chapter 3 the current state of AI development in RTS games is analyzed highlighting the struggles of the gaming industry to produce valuable. The focus on improving multiplayer experience has impacted gravely on the quality of the AIs thus leaving them with serious flaws that impair their ability to challenge and entertain players. Chapter 4 explores different aspects of AI development for RTS, evaluating the potential strengths and weaknesses of an agent-based approach and analysing which aspects can benefit the most against centralized AIs. Chapter 5 describes a generic agent-based framework for RTS games where every game entity becomes an agent, each of which having its own knowledge and set of goals. Different aspects of the game, like economy, exploration and warfare are also analysed, and some agent-based solutions are outlined. The possible exploitation of self-computing properties to efficiently organize the agents activity is then inspected. Chapter 6 presents the design and implementation of an AI for an existing Open Source game in beta development stage: 0 a.d., an historical RTS game on ancient warfare which features a modern graphical engine and evolved mechanics. The entities in the conceptual framework are implemented in a new agent-based platform seamlessly nested inside the existing game engine, called ABot, widely described in Chapters 7, 8 and 9. Chapter 10 and 11 include the design and realization of a new agent based language useful for defining behavioural modules for the agents in ABot, paving the way for a wider spectrum of contributors. Chapter 12 concludes the work analysing the outcome of tests meant to evaluate strategies, realism and pure performance, finally drawing conclusions and future works in Chapter 13.

This thesis proposes design methods and test tools, for optical systems, which may be used in an industrial environment, where not only precision and reliability but also ease of use is important. The approach to the problem has been conceived to be as general as possible, although in the present work, the design of a portable device for automatic identification applications has been studied, because this doctorate has been funded by Datalogic Scanning Group s.r.l., a world-class producer of barcode readers. The main functional components of the complete device are: electro-optical imaging, illumination and pattern generator systems. For what concerns the electro-optical imaging system, a characterization tool and an analysis one has been developed to check if the desired performance of the system has been achieved. Moreover, two design tools for optimizing the imaging system have been implemented. The first optimizes just the core of the system, the optical part, improving its performance ignoring all other contributions and generating a good starting point for the optimization of the whole complex system. The second tool optimizes the system taking into account its behavior with a model as near as possible to reality including optics, electronics and detection. For what concerns the illumination and the pattern generator systems, two tools have been implemented. The first allows the design of free-form lenses described by an arbitrary analytical function exited by an incoherent source and is able to provide custom illumination conditions for all kind of applications. The second tool consists of a new method to design Diffractive Optical Elements excited by a coherent source for large pattern angles using the Iterative Fourier Transform Algorithm. Validation of the design tools has been obtained, whenever possible, comparing the performance of the designed systems with those of fabricated prototypes. In other cases simulations have been used.

Il mercato, in questi ultimi dieci anni, si è modificato in un qualcosa di più globale e competitivo. Questa trasformazione ha imposto alle imprese l’adozione di strategie orientate all’innovazione di prodotto e di processo, e all’efficienza industriale “Environmentally friendly” di lungo periodo. Le aziende, infatti, per competere sia nel territorio nazionale sia in quello internazionale, sono alla costante ricerca di una continua ottimizzazione, attraverso il processo “deming” del miglioramento continuo, delle proprie prestazioni; spesso però capita che massimizzino esclusivamente la performance produttiva, che è stata migliorata con l’introduzione, oramai da circa 35 anni, della Lean production e oggi quindi presenta limitati margini di miglioramento. È alla luce di questo ragionamento che le aziende, quelle più lungimiranti, stanno cercando di dirigersi verso un’altra direzione, ovvero quella che mira a ridurre gli sprechi e le perdite, di risorse naturali, nei processi produttivi, in accordo coi principi della sostenibilità ambientale. Considerando le quantità di risorse naturali messe in gioco in grandi aziende quali la VM Motori S.p.A. possiamo intuire quanta marginalità di miglioramento potremmo ottenere con l’attuazione di processi di miglioramento focalizzati sui singoli aspetti. I primi due capitoli trattano il tema dello sviluppo sostenibile e del S.G.A. in Italia e all’estero. Nel capitolo 3 introduco l’Azienda, descrivo tutte le fasi di processo per la fabbricazione di varie tipologie di motori rigorosamente diesel, l’impianto elettrico, termico e di aria compressa. Nel capitolo 4 faccio l’analisi di tutti gli aspetti e gli impatti ambientali; inoltre, per ogni fattore d’impatto ambientale, verrà compilata la cosiddetta VIA che sarà riassunta nell’ultimo paragrafo. Nel capitolo 5 affronto il concetto del miglioramento continuo applicando la filosofia del World Class Manufacturing che è stato implementato in Azienda.

The volume consists of twenty-five chapters selected from among peer-reviewed papers presented at the CELDA (Cognition and Exploratory Learning in the Digital Age) 2013 Conference held in Fort Worth, Texas, USA, in October 2013 and also from world class scholars in e-learning systems, environments and approaches. The following sub-topics are included: Exploratory Learning Technologies (Part I), e-Learning social web design (Part II), Learner communities through e-Learning implementations (Part III), Collaborative and student-centered e-Learning design (Part IV). E-Learning has been, since its initial stages, a synonym for flexibility. While this dynamic nature has mainly been associated with time and space it is safe to argue that currently it embraces other aspects such as the learners’ profile, the scope of subjects that can be taught electronically and the technology it employs. New technologies also widen the range of activities and skills developed in e-Learning. Electronic learning environments have evolved past the exclusive delivery of knowledge. Technology has endowed e-Learning with the possibility of remotely fomenting problem solving skills, critical thinking and team work, by investing in information exchange, collaboration, personalisation and community building.
