L'explosion démographique a conduit à une augmentation intensive des contaminants environnementaux issus de différentes émissions anthropiques, par exemple, les hydrocarbures de pétrole, les pesticides, les biphényles polychlorés (BPC) ainsi que d’autres déchets ménagers tels que les détergents utilisés comme nettoyants ménagers. Du fait de leur persistance et du point de vue toxicologique, les résidus de ces contaminants organiques, qui peuvent être détectés dans les différentes matrices environnementales (eau, sédiments, air et biotes), parfois à très faible concentration (micropolluants), ont conquis l'attention du public. Cette étude vise à déterminer les niveaux de concentration de contaminants sélectionnés dans les sédiments de surface et à identifier la source de ces produits chimiques dans le ruisseau Cortiou. Les résultats ont montré une forte contamination par les hydrocarbures dans la zone étudiée. De plus, ces résultats ont probablement reflété le fait que les processus de biodégradation se sont produits parallèlement à une répartition chronique des charges d’épuration non traitées. Ces polluants organiques ont également confirmé un effet néfaste sur le biote marin et plus particulièrement sur les communautés benthiques pour certaines stations / Demographic explosion has led to increase intensively environmental contaminants issued from different anthropogenic release e.g. petroleum hydrocarbons, pesticides, polychlorinated biphenyls (PCBs) and also other domestic waste such as detergents as household cleaner. Due to their persistence and the toxicological point of view, the remnants of these organic contaminants, which can be detected in the different environmental matrices (water, sediment, air and biota), sometimes with very low concentration (micropollutants), has gained the public attention. This study aims to determine the concentration levels of selected contaminants in surficial sediments and identifying the source of these chemicals in Cortiou Creek. The results showed high contamination by hydrocarbons in the studied area. Additionally, these results probably reflected that biodegradation processes occurred concomitantly with a chronic apportionment of untreated sewage loading. These organic pollutants also confirmed an adverse effect for marine biota and more particularly for benthic communities for some stations

This thesis presents the development and results of a research work that proposes a method of designing incremental services that works for knowledge management environments via Internet, called e-services. This method is based on the principles of collaborative design-by which all organizational profiles provide specific design tasks, and the idea of incremental progression of projects, increasing at each stage of production the formal features and functionality artifact. The thesis begins with a theoretical study in which we present the main concepts and features three main areas: 1) new business models and scenarios that emerge from them, as so-called "open innovation" and "living labs"; 2) The research in the design field, which involved paradigms as "collaborative design" that governs the development of this doctoral research; 3) Theory of distributed cognition, studying the characteristics of cognitive development of subjects in different environments using different types of artifacts. A second part of the thesis presents the results of empirical exploration based on the concepts, features and phases of action research method. This chapter presents the incremental design method -main contribution of the thesis- and explains how it has been tested on two projects undertaken by the organization in which research is conducted. These projects make contributions in two different environments in knowledge management area. The projects are the development (following the proposed method) of e-health service to support the treatment of the disease of dysphagia; and systematization of incremental design method by implementing a workflow tool that is useful in everyday activity of the collective multidisciplinary research that develops the thesis. From empirical exploration emerge qualitative and quantitative results that are intended to validate the proposed methodology and are exposed in the thesis document. Finally, the last chapter presents general conclusions and specific work and contributions this makes to the scientific community, as well as suggesting some future research that may follow the experience presented here. / El presente documento presenta la evolución y resultados del trabajo de investigación que tiene como objetivo proponer un método incremental de diseño de servicios concebidos para entornos de gestión del conocimiento a través de Internet, denominados e-services. Dicho método se basa en los principios del diseño colaborativo -según los cuales todos los perfiles de la organización aportan tareas de diseño específicas- y en la idea de la progresión incremental de los proyectos, aumentando en cada fase de producción las funcionalidades y características formales del artefacto. El método propuesto ha sido puesto en práctica por un grupo de investigación multidisciplinario dedicado a la realización de diversos proyectos en el ámbito de la gestión del conocimiento.

This dissertation is divided into three major sections (one on dendrimers, one on tripodal metal ligands and one on a research oriented chemistry curricula) with a primary focus on different types of multicomponent assemblies. In the first chapter, a system is described that used a multicomponent assembly of AT-PAMAM dendrimers and an indicator, carboxyfluorescein, to detect and identify various polyanions at a low micromolar concentration. The system was able to successfully differentiate twelve anions, many of biological interest, including three tricarboxylates. The tricarboxylates were differentiated based primarily on the regiochemistry of the anionic groups. In the second chapter, further studies with AT-PAMAM dendrimers were carried out to provide some understanding of the thermodynamic origins of binding. Utilizing isothermal titration calorimetry, the binding of the dendrimers to large polyanionic dendrons with increasing numbers of charges was studied. Through these studies, the thermodynamic values of the binding events were obtained allowing us to explore the properties of the dendrimers. The cooperativity of the system was measured, and primarily negative cooperativity determined by the entropic contributions was uncovered. As the dendrimers increased in size, the thermodynamic origins of binding were determined to a greater extent by the entropy of binding. In the third chapter, a novel dynamic ligand system for metal binding is described. In the presence of a metal salt, a heterocyclic aldehyde and a secondary amine with two heterocyclic arms reversibly condense to form a hemiaminal with a tripodal metal binding site. This chapter describes studies on the metal binding ability, the variety of metals that will lead to this formation, the effects of anions and the range of aldehydes that can be used are described. Furthermore, the system’s reversibility was explored. Finally, the use of a bistriazole secondary amine was explored. The modular nature of triazole formation could lead to the introduction of additional functionalities. The fourth chapter discusses how the novel ligand system could be used to study the enantiomeric excess (ee) of chiral thiols. Based upon the system’s ability to form a stable hemiaminal thioether, a CD signal could be generated that is proportional to the amount of a particular enantiomer in solution. Using this system, a calibration curve relating CD signal and ee can be generated giving the ee of an unknown solution. In the final chapter, a look at the Freshman Research Initiative will be carried out with a focus on the ability to teach basic skills in an introductory laboratory through research. Four different skills or techniques will be explored through three different FRI streams,x and how they teach the four skills. Finally, analysis of the success of the program, particularly students’ success in the next laboratory course in the sequence, is discussed, and a model for adopting this type of teaching at other universities is given. / text

In 1880, French brothers Jacques and Pierre Curie discovered the phenomenon of piezoelectricity in naturally occurring quartz crystal, sometimes referred to as 'nature's timekeeper.' By 1959, tens of millions of devices that exploited quartz crystal's piezoelectric character were being used in the technologies of radio, telephony, and electronic timekeeping. This dissertation analyzes the rapid rise of quartz crystal technology in the United States by looking at the growth of its knowledge base as reflected primarily in patents and journal articles. The major finding of this analysis is that the rise of quartz crystal technology cannot be fully understood by looking only at individuals, institutions, and technological factors. Rather, this work posits that the concept of technological community is indispensible in explaining rapid technological growth and diffusion that would otherwise seem inexplicable. In the late 1920s, and again in the early 1940s, the knowledge base of quartz crystal technology experienced exponential growth, partly due to U.S. government patronage and enlightened regulation. However, as this study shows, quartz crystal engineers, scientists, and entrepreneurs could not have mobilized as quickly and effectively as they did unless a vibrant technological community already existed. Furthermore, the United States' ability to support such a thriving community depended in part on an early 20th century American culture that displayed an unmatched enthusiasm for democratic communications media, most especially broadcast radio and universal telephone service. Archival records, professional journal articles, government reports, manufacturer catalogs, and U.S. patents have been used to document this history of the quartz crystal technological community. This dissertation contributes to the literature on technological communities and their role in facilitating technological and ecomonic growth by showing that though such communities often form spontaneously, their growth may be nurtured and stimulated through enlightened government regulation. As such, this dissertation should be of interest to scholars in the fields of history of technology, business history, management studies, and public policy.

Na maioria das escolas públicas a presença dessas tecnologias, representada pelo computador, aconteceu com a criação dos laboratórios de informática. Estudos já desenvolvidos por inúmeros pesquisadores da área educacional evidenciaram que a criação dos laboratórios de informática não garantiu que esse instrumento fosse usado como auxiliar na construção do conhecimento pelos alunos devido à desconexão com os conteúdos do currículo. Com o objetivo de articular o uso do laboratório de informática com os conteúdos curriculares de 1º ao 5º ano do Ensino Fundamental, esta pesquisa de abordagem qualitativa com características de pesquisa-ação, porém, de metodologia experimental e participante propôs uma intervenção para o uso dos computadores como auxiliares ao processo pedagógico, por meio de um curso de formação continuada em serviço desenvolvido com 24 professores de uma escola pública municipal numa cidade de pequeno porte localizada no interior da região centro-oeste do estado de São Paulo. Como produto deste estudo de Mestrado Profissional, elaboramos um livro em formato digital com sugestões para o trabalho com professores no laboratório de informática. Verificamos que apesar do receio inicial na utilização do computador, os professores demonstraram-se interessados e participativos durante a realização das atividades do curso e assim contribuindo para que o laboratório de informática educacional torne-se um local de construção de conhecimentos favorável ao processo de ensino e aprendizagem. / Information and Communication Technologies (ICT) entered school environments to be auxiliary means to the process of teaching and learning. In most public schools, the presence of these technologies, which is represented by computers, happened with the setting of computer labs. Studies previously developed by several researchers of the educational field made it clear that the setting of computer labs did not guarantee that such tools were used to help students in their knowledge construction because of the disconnection with curriculum contents. Aiming at articulating the use of computer labs with the contents of Elementary School 1st to 5th year, this study, which had a qualitative approach with characteristics of an action research and used an experimental and participative methodology, purposed an intervention for the use of computers as helpers to the pedagogical process through a teachers’ continuous training during service developed with 24 individuals in a local public school of a small town in the countryside of São Paulo. As an outcome of this study for Professional Master Degree, we elaborated a digital book with suggestions for the work with teachers in computer labs. We verified that, even being insecure about using computers, teachers like such technology and showed themselves interested and participative during the training activities and, thus, contributed for educational computer labs to become knowledge construction places which are favorable to the process of teaching and learning.

Concentra-se no surgimento, em anos recentes, dos assim chamados laboratórios experimentais - espaços articulados em rede nos quais tal produção toma corpo. São abordadas sob tal perspectiva denominações tais como labs de mídia, hackerspaces, Fablabs, entre outras. A pesquisa analisa alguns desses modelos sobre o pano de fundo do imaginário tecnoutópico, que afirma as tecnologias de informação como instrumentos de combate à burocratização e à alienação da sociedade. Com o objetivo de questionar a usual associação dos labs experimentais em termos gerais ao desenvolvimento da cibernética e em particular ao histórico do estadunidense MIT Media Lab, a pesquisa explora outros fios narrativos para os múltiplos campos que influenciam a formação dos labs. Debruça-se ainda sobre o diálogo entre, de um lado, o contexto contemporâneo dos labs em diferentes partes do mundo, e de outro a contribuição da ideia de uma cultura digital particularmente brasileira - que ao longo da última década proporcionou a construção de um discurso que aproximava software livre, diversidade cultural e políticas públicas de inclusão social. São debatidos em particular dois eixos da cultura digital brasileira: o compensatório, que buscaria corrigir distorções históricas incluindo populações na chamada era da informação; e o exploratório, que buscaria criticar e influenciar os caminhos futuros da articulação entre tecnologia e sociedade. A dissertação relata ainda pesquisa de campo desenvolvida na Finlândia, onde foram vivenciados a preparação de um festival internacional de arte e tecnologia, visitas a diferentes espaços que se situam no campo dos labs experimentais, e o contato pessoal com integrantes de grupos e coletivos que atuam na fronteira entre cultura e tecnologia. Tais experiências contribuíram para a compreensão de elementos importantes dos labs experimentais, principalmente o aspecto da não conformação às expectativas de uma sociedade cada vez mais regida pela transformação de toda expressão cultural em valor econômico. Esse entendimento é aprofundado ao fim da dissertação na imagem do lab experimental como espaço em branco que, ao mesmo tempo em que funciona como interface entre redes digitais e as dinâmicas particulares dos locais onde se encontram, também situam-se como instâncias de resistência e reinvenção frente ao capitalismo informacional de matriz cibernética / Abstract: This dissertation reports on discoveries, hypotheses and conclusions of research on a kind of collaborative production that connects arts, science, activism, innovation, design, among other areas. It focuses on the appearing, in recent years, of the so-called experimental labs ¿ network articulated spaces in which such a production comes into being. Under that perspective are approached denominations such as media labs, hackerspaces, Fablabs, among others. The research analyses some of these models against the background of techno-utopian imaginary, which asserts information technologies as tools to fight against burocracy and allienation of society. With the goal of questioning the usual association of experimental labs in general to the development of cybernetics and particularly to the history of MIT Media Lab in the USA, the research explores other narrative threads for the multiple fields that influence the formation of labs. Attention is paid to the dialogue between, on one side, the contemporary context of labs in different parts of the wirld, and on the other the contribution of the idea of a particularly brazilian digital culture ¿ which over the last decade offered the possibility of building a discourse that draws closer free (open) software, cultural diversity and public policies for social inclusion. Two particular axes of the brazilian digital culture are discussed: the compensatory, which seeks to correct historical distortions by including populations in the so-called information age; and the exploratory, that seeks to criticize and influence future paths of the articulation of technology and society. The dissertation reports as weel on field research undertaken in Finland, where were experimented the preparation of an international festival on arts and technology, visits to different spaces situated on the field of experimental labs, and personal contact with members of groups and collectives that work on the border of culture and technology. Such experiences contributed to the understanding of important elements of experimental labs, especially the aspect of non-conformation to the expectations of a society increasingly ruled by the transformation of every cultural expression into economic value. This understanding is deepened by the end of the dissertation on the image of the experimental lab as a blank space that, as well as working as an interface between digital networks and the particular dynamics of the places in which they are located, are also situated as instances of resistance and reinvention before the cybernetical informational capitalism / Mestrado / Divulgação Científica e Cultural / Mestre em Divulgação Científica e Cultural

Currently society is facing a set of interconnected challenges, known collectively as the Sustainability Challenge, which are systematically increasing socio-ecological unsustainability on a scale never experienced before.  In order to address the Sustainability Challenge, Social Labs provide an approach that is systemic, participatory and emergent, enabling solutions that are responsive to the dynamic nature of those interconnected challenges. Our research explores how a specific lab - U.Lab - can be re-designed in order to move society strategically toward a sustainable future. We use the Framework for Strategic Sustainable Development, designed to help practitioners to facilitate society’s transition towards sustainable development, as well as concepts of strategic sustainable development, which support s shift from unsustainable systems, structures and practices towards sustainable ones in a strategic way. Our research follows Design Research Methodology (DRM). DRM aims for the formulation, validation and development of theories and models in the field of design. U.Lab’s experiential response to the Sustainability Challenge inspires participants to question paradigms of thought and societal norms. However, U.Lab is still an emerging social technology and lacks boundary conditions and a scientific basis for understanding our current reality and creating the solutions that will lead society systematically towards a sustainable future.
