Las redes sociales son una de tantas posibles explicaciones al por qué la gente se adhiere a los movimientos sociales y participa de sus luchas. Sin embargo, los acercamientos que se han hecho a la militancia desde las redes sociales tienden a ser rígidos, debido a que sólo diferencian entre los que militan y los que no militan, dejando fuera del espectro una gran cantidad de matices que existen entre las personas que pertenecen a un movimiento social determinado. Este estudio de caso trata de responder a este interrogante con el concepto de compromiso, el cual es un intento de matizar la militancia en un movimiento social desde la teoría de las redes sociales. Adicionalmente, esta investigación trata de acercarse al fenómeno poco conocido del ambientalismo al sur de Bogotá. El cual es un movimiento social joven, en pleno proceso de expansión, con muchos simpatizantes y militantes, pero poco conocido por la academia y por la gente que no habita este espacio.

En una tesi anterior (Puig, 2004) es varen estudiar els aspectes mecànics vinculats al desfibratge i als consums energètics associats al procés de desintegració per acabar quantificant les forces implicades en el procés d'individualització dels components de diferents paperots. Aquest estudi, ha permès conèixer les condicions de desintegració que condueixen a un mínim consum energètic, aspecte complementari al reciclatge i destintatge del paperot però molt important per aconseguir un procés realment sostenible. Degut als requeriments del mercat, hi ha un altre aspecte o vessant realment important com és l'eliminació de tinta. Aquest procés, malgrat la complexitat industrial, es pot reduir o simplificar en dues etapes: la desintegració i la flotació. Ambdues, per raons d'eficàcia i condicionades pels agents químics que s'utilitzen, es realitzen en medi fortament alcalí (entorn d'un pH a 12). Aquest fet, genera una forta contaminació (DQO elevada) i per tant, és un procés poc respectuós amb el medi ambient. Els factors que condicionen treballar en medi alcalí són principalment, el despreniment de la tinta del suport, clarament accelerat en medi bàsic i fonamental per un bon destintatge i la utilització de tensioactius aniònics. Aquests tensioactius són sensibles al pH i la seva eficàcia disminueix en medi neutre o quasi neutre. Atès el que s'ha exposat, s'ha plantejat aquesta tesi que porta per títol "Aspectes Físics i Químics del Destintatge de Paper Revista mitjançant Tensioactius Catiònics", com un estudi del procés de destintatge de paper revista recuperat parant especial atenció a les variables físico-químiques i mecàniques del procés i a la seva influència en el despreniment i fragmentació de la tinta, així com en el procés d'eliminació de la tinta per flotació per tal d'avaluar la viabilitat d'un procés de destintatge en medi neutre enfront del destintatge alcalí convencional. S'ha utilitzat, com a paperot a destintar, el paper revista ja que aquest tipus de paper representa un percentatge elevat del paper recuperat a la Unió Europea. A més, aquest tipus de paper és utilitzat habitualment en les plantes de destintatge industrials per millorar les propietats de les suspensions destintades de paper de diari. La utilització de tensioactius catiònics és deguda a que la seva activitat no es veu afectada pel pH de la suspensió. Així, durant la comparació dels processos de destintatge en medi neutre i en medi alcalí, les eficàcies dels processos no es veuran influenciades pel grau d'ionització del tensioactiu. Donada l'absència d'estudis sobre la influència de les variables del procés en les mesures de concentració efectiva de tinta residual (ERIC) i ja que s'ha emprat aquest paràmetre per avaluar el despreniment i fragmentació de la tinta durant l'etapa de desintegració. En primer lloc, s'ha plantejat un estudi fonamental de la influència que poden tenir les variables del procés (granulometria, concentració de tinta i tipus de suport) en aquest paràmetre. Pel que fa a l'etapa de flotació, s'estudiarà l'efectivitat d'aquesta etapa, posant especial atenció a la capacitat del tensioactiu per eliminar tota la tinta despresa en l'etapa de desintegració. A més, donada la poca informació bibliogràfica referida als mecanismes de flotació amb tensioactius catiònics i la influència que té l'adsorció d'aquests agents per part de la suspensió paperera en l'etapa de flotació, s'ha dut a terme un estudi de l'adsorció dels tensioactius catiònics per part dels components d'una suspensió paperera. Per tant, la tesi realitzada té com a objectius:  Estudi fonamental de les mesures de ERIC (concentració efectiva de tinta residual) amb suports específics.  Estudi de la desintegració en medi neutre i comparació amb la desintegració clàssica.  Modelització del desfibratge de paperot a l'etapa de desintegració.  Estudi de l'eliminació de tinta per flotació en medi neutre i comparació amb la flotació clàssica.  Estudi del mecanisme d'adsorció de tensioactius en suspensions de cel·lulosa sintètica i de paperot.

Com o avanço da tecnologia cada vez mais acessível, torna-se imprescindível acompanhar este mesmo desenvolvimento e adotá-lo para a obtenção de um melhor produto. Sendo as formas farmacêuticas estéreis alvo de uma rigorosa avaliação dos seus requisitos, é uma grande vantagem conhecer quais as orientações atuais para o fabrico destes produtos. Uma vez que estamos na era da “aldeia global”, é inquestionável a necessidade de conhecer documentos de outros países, isto porque na indústria farmacêutica, tal como em muitas outras, há o objetivo de expandir a comercialização de produtos para outros países, continentes, mas há que ter em atenção que para esses países os requisitos de qualidade desses produtos podem não ser iguais aos do nosso país. Ao conhecer e aplicar os principais e mais rígidos controlos e normas, é certo que todos os outros serão cumpridos. Como principais documentos que regulam e orientam o processo de fabrico destes produtos existem as Good Manufacturing Practices, as normas da Internactional Standardization Organization e as Farmacopeias de vários países. Na indústria farmacêutica, principalmente no fabrico das formas farmacêuticas estéreis, há controlo não só do processo de fabrico e produto final, como também de todo o ambiente e intervenientes que envolvem a produção. Dentro das formas farmacêuticas em estudo encontram-se as de uso oftálmico, de aplicação nasal, de aplicação auricular e de uso parenteral. Todas estas têm o principal requisito de ser estéreis, variando nos outros parâmetros, como tonicidade e pH de acordo com a localização da administração. Os ensaios realizados tanto em In Process Control como no produto final, estão presentes nas Farmacopeias, que serão discutidos e comparados entre si.

The integration of Biographical Knowledge in research processes is a methodological proposal of critical empiricism that shifts the centre of production of knowledge to the research objects. We try to show haw Biographical Narratives can allow bypassing the locks and the deviations from real observation by the researcher and focus is work on actors in process. In the critique of the Eurocentric paradigm and is production of hegemonic scientific discourses by Bonaventura Sousa Santos (Santos, 2000) proposes the "south epistemologies" as a research process and the inclusion of knowledge of actors as the research field. In the article we will try to look at the process of production of biographical narratives using the tools of south epistemological proposal. We start reviewing the methodologies working on biographical objects. Then we present the preliminary studies and research we have been doing in communities in southern Mozambique in Djabula Community Centre. These results should be completed with other works on the ground, and now we opened as a collaborative process discussion on African Studies community. The project will be completed in the coming months, through the proposal of a "House of memories" to develop with the local population through articles, stories, sounds and dances that are chosen and will support the chosen narratives by the community. The projects created with local players, from their problems allow rapprochement and dialogue between the different knowledge.

The aim of this study was, within a sensitivity analysis framework, to determine if additional model complexity gives a better capability to model the hydrology and nitrogen dynamics of a small Mediterranean forested catchment or if the additional parameters cause over-fitting. Three nitrogen-models of varying hydrological complexity were considered. For each model, general sensitivity analysis (GSA) and Generalized Likelihood Uncertainty Estimation (GLUE) were applied, each based on 100,000 Monte Carlo simulations. The results highlighted the most complex structure as the most appropriate, providing the best representation of the non-linear patterns observed in the flow and streamwater nitrate concentrations between 1999 and 2002. Its 5% and 95% GLUE bounds, obtained considering a multi-objective approach, provide the narrowest band for streamwater nitrogen, which suggests increased model robustness, though all models exhibit periods of inconsistent good and poor fits between simulated outcomes and observed data. The results confirm the importance of the riparian zone in controlling the short-term (daily) streamwater nitrogen dynamics in this catchment but not the overall flux of nitrogen from the catchment. It was also shown that as the complexity of a hydrological model increases over-parameterisation occurs, but the converse is true for a water quality model where additional process representation leads to additional acceptable model simulations. Water quality data help constrain the hydrological representation in process-based models. Increased complexity was justifiable for modelling river-system hydrochemistry. Increased complexity was justifiable for modelling river-system hydrochemistry.

Purpose: Increasing costs of health care, fuelled by demand for high quality, cost-effective healthcare has drove hospitals to streamline their patient care delivery systems. One such systematic approach is the adaptation of Clinical Pathways (CP) as a tool to increase the quality of healthcare delivery. However, most organizations still rely on are paper-based pathway guidelines or specifications, which have limitations in process management and as a result can influence patient safety outcomes. In this paper, we present a method for generating clinical pathways based on organizational semiotics by capturing knowledge from syntactic, semantic and pragmatic to social level. Design/methodology/approach: The proposed modeling approach to generation of CPs adopts organizational semiotics and enables the generation of semantically rich representation of CP knowledge. Semantic Analysis Method (SAM) is applied to explicitly represent the semantics of the concepts, their relationships and patterns of behavior in terms of an ontology chart. Norm Analysis Method (NAM) is adopted to identify and formally specify patterns of behavior and rules that govern the actions identified on the ontology chart. Information collected during semantic and norm analysis is integrated to guide the generation of CPs using best practice represented in BPMN thus enabling the automation of CP. Findings: This research confirms the necessity of taking into consideration social aspects in designing information systems and automating CP. The complexity of healthcare processes can be best tackled by analyzing stakeholders, which we treat as social agents, their goals and patterns of action within the agent network. Originality/value: The current modeling methods describe CPs from a structural aspect comprising activities, properties and interrelationships. However, these methods lack a mechanism to describe possible patterns of human behavior and the conditions under which the behavior will occur. To overcome this weakness, a semiotic approach to generation of clinical pathway is introduced. The CP generated from SAM together with norms will enrich the knowledge representation of the domain through ontology modeling, which allows the recognition of human responsibilities and obligations and more importantly, the ultimate power of decision making in exceptional circumstances.

Wheat Distillers’ Dried Grains with Solubles (DDGS) and in-process samples were used for protein extraction. Prolamins were the predominant protein components in the samples. The absence of extractable α- and γ-gliadins in DDGS indicated protein aggregation during the drum drying processing stage. Prolamin extraction was performed using 70% (v/v) ethanol or alkaline-ethanol solution in the presence of reducing agent. DDGS extracts had relatively low protein contents (14-44.9%, w/w), regardless of the condition applied. The wet solids were the most suitable raw material for protein extraction, with recovery yields of ~ 55% (w/w) and protein content of ~58% (w/w) in 70% (v/v) ethanol. Protein extracts from wet solids were significantly rich in glutamic acid and proline. Mass balance calculations demonstrated the high carbohydrate content (~ 50%, w/w) of solid residues. Overall, the feasibility of utilising in-process samples of DDGS for protein extraction with commercial potential was demonstrated.

A aplicação de técnicas de estudo de sistemas em ambientes industriais com grande concorrência, é cada vez mais significativa devido às modificações e flexibilidade de produção exigidas. A aplicação de técnicas de análise e ajustes de layouts são algumas destas técnicas que podem trazer resultados competitivos positivos. O presente trabalho descreve os tipos de layouts existentes, com suas aplicações, vantagens e desvantagens com a finalidade de analisar e propor melhorias em layouts de processo na indústria coureira. O trabalho enfoca ainda os principais pontos a serem considerados quando da criação de um novo layout ou do ajuste e/ou melhoria de um existente. Para tal, foi realizado um estudo de caso utilizando a técnica de Melhoria de Layout de Silveira (1998), com a aplicação do Planejamento Sistemático de Layout em um layout de processo do setor da Secagem, característico em uma indústria beneficiadora de couro. Os resultados obtidos traduzem o re-arranjo de seus postos de trabalho com redução do fluxo de material de acordo com a aproximação de postos com relações de afinidade. Essa alteração possibilitou uma melhor organização espacial dos postos de trabalho e um melhor controle da produção, através da separação natural dos lotes. A metodologia adotada pode ser utilizada como ferramenta de melhoria nos demais setores, tanto da própria empresa, como do mercado coureiro em geral.

Este trabalho de conclusão investiga o efeito da geração de estoques intermediários nos indicadores principais empregados na Teoria das Restrições (Ganho, Despesa Operacional e Inventário) em uma unidade industrial de processo produtivo de Propriedade contínuo, que emprega embalagens, matérias-primas obtidas em larga escala e cadeias logísticas de longo curso. Este tipo de indústria produz bens de consumo imediato, com pouca variabilidade, de modo “empurrado”. A principal conseqüência é a perda do sincronismo na cadeia logística, resultando em uma grande quantidade de estoques intermediários e custos crescentes, relacionados principalmente ao custo de manutenção destes estoques. Através dos cinco passos de focalização e das ferramentas lógicas da Teoria das Restrições, propõe-se uma alternativa gerencial, que inclui o algoritmo Tambor-Pulmão-Corda e insere a organização em um processo de melhoria contínua, cujos impactos são avaliados por simulação computacional. Através de técnicas estatísticas e software apropriados, constrói-se um modelo de simulação computacional baseado em dados reais de uma planta produtora de cimento. A partir deste modelo, diferentes cenários são testados, descobrindo-se a condição ótima. Chega-se a uma conclusão, considerando a mudança na política de geração de estoques intermediários e seus impactos na redução de custos e riscos.

O objetivo deste trabalho é identificar os impactos do processo de internacionalização retomado no início da década de noventa e a construção do posicionamento estratégico brasileiro ao longo de todos os seus ciclos históricos. Este trabalho objetivou também identificar as dimensões da competitividade de uma nação e confrontá-las com o processo de evolução do comércio internacional através dos séculos, bem como, os efeitos do fenômeno da globalização e a aplicação das orientações do marketing internacional como referencial para a construção do posicionamento estratégico das nações. Concluímos que a competitividade das nações deve ser entendida e avaliada através dos resultados comparativos de sua produtividade e, conseqüentemente, do nível de qualidade de vida proporcionado aos seus cidadãos. A formulação de estratégias para a internacionalização da nação e suas indústrias pode viabilizar que estes objetivos, no campo da produtividade, sejam alcançados ou, caso sejam mal formulados, poderão distanciá-los da nação. Por este motivo, a competitividade nacional tomou-se uma das principais preocupações tanto para os governos que estão inseridos, como para os que se encontram em processo de inserção competitiva internacional.

The characteristics of the Brazilian historic context, under which the predominant social relations have developed, have led to a process of income concentration and to the political power of the dominant classes. The slavery abolishment hasn't guaranteed the people the rights secured to privileged citizens in general. Such practices were observed during historic process as the low level literacy shown by the census of 1920, the political domination of oligarchies and the military coup, all as determining factors in process of political power concentration. The social indicators and the corruption are extremely unfavorable to our country, but we wonder if that happens only in underdeveloped societies. It is possible that even the American society, even the most developed societies, under the democratic capitalism, can suffer negative consequences of some corruption in the capitalism system. Our observations have led to the perception that all democratic society must be regulated by the State in order to preserve the stability of the system. It has also been observed that it is necessary more effective popular participation in order to neutralize economic groups¿ pressure. It has also become evident the necessity of reduction of commissioned office in the federal public administration. And, finally, it is fundamental to propose an amendment to the construction that allows the Public Ministry to have access to any bank, fiscal or telephonic information of anyone that is in office: It should be called "The Law of Moral Transparency". Those proposals will only be possible if there is massive popular participation and we hope that they express our people¿s will in order to appose to those who act only to obtain private benefits.

Day after day, even small companies and multinationals brands need to compete in a worldwide market. All kind of global strategies have to involve production and regional market knowledge. Still being essential for company have a complete view of it market and it right position to gain competitive advantage. In a global market, get possible for the companies be in touch with last generation technologies and equipment's and all kind of research. Companies like that should develop products focused in customer's desire, even those extremely strict. Specifically in our country, as hard as we could think, the companies have access to credit lines, to the fiscal incentives offered by the states that alliance with the market potential are making possible the appearance of a lot companies and the growth of the companies already existent. However, these resources alone don't produce results to the company if it doesn't possess an internal organization able to assimilate the new market situation. The companies have to be able to apply the maximum resources offered by new technologies and understand how a communications facility means solution for many internal problems. In short terms, technology, financial resources, research and knowledge are available, however, the human resources might be prepared and developed in order to become the whole knowledge in profits. According 'JURAN' and his Total Quality Control philosophy the human resources playing fundamental role in the process, and in my opinion a company is something like a ship where all must be prepared to hold the rudder. I will develop a basic job looking for productivity and company's development through the people's involvement, focused in process of motivation, creativity and staff valorization. I believe that there no good production process without those requirements. Based on real case of a automotive parts and foundry company, located in Bento Gonçalves - RS, this work will look for to organize it mainly in its Industrial Division, adopting in participate administration where, through a information system and personnel involvement we will seek all favorable conditions to politics and strategies in get the growth of company.
