La gestió de l'aigua residual és una tasca complexa. Hi ha moltes substàncies contaminants conegudes però encara moltes per conèixer, i el seu efecte individual o col·lgectiu és difícil de predir. La identificació i avaluació dels impactes ambientals resultants de la interacció entre els sistemes naturals i socials és un assumpte multicriteri. Els gestors ambientals necessiten eines de suport pels seus diagnòstics per tal de solucionar problemes ambientals. Les contribucions d'aquest treball de recerca són dobles: primer, proposar l'ús d'un enfoc basat en la modelització amb agents per tal de conceptualitzar i integrar tots els elements que estan directament o indirectament involucrats en la gestió de l'aigua residual. Segon, proposar un marc basat en l'argumentació amb l'objectiu de permetre als agents raonar efectivament. La tesi conté alguns exemples reals per tal de mostrar com un marc basat amb agents que argumenten pot suportar diferents interessos i diferents perspectives. Conseqüentment, pot ajudar a construir un diàleg més informat i efectiu i per tant descriure millor les interaccions entre els agents. En aquest document es descriu primer el context estudiat, escalant el problema global de la gestió de la conca fluvial a la gestiódel sistema urbà d'aigües residuals, concretament l'escenari dels abocaments industrials. A continuació, s'analitza el sistema mitjançant la descripció d'agents que interaccionen. Finalment, es descriuen alguns prototips capaços de raonar i deliberar, basats en la lògica no monòtona i en un llenguatge declaratiu (answer set programming). És important remarcar que aquesta tesi enllaça dues disciplines: l'enginyeria ambiental (concretament l'àrea de la gestió de les aigües residuals) i les ciències de la computació (concretament l'àrea de la intel·ligència artificial), contribuint així a la multidisciplinarietat requerida per fer front al problema estudiat. L'enginyeria ambiental ens proporciona el coneixement del domini mentre que les ciències de la computació ens permeten estructurar i especificar aquest coneixement.

Constipation is a common problem for people with dementia and it may result in discomfort, suffering and lower quality of life. Nurses in municipal nursing homes have difficult to observe and prevent these problems because they do not participate in the daily caring work. The aim of this study was to illustrate the nurse assistants’ reflections about the care they gave people with dementia and constipation. Main questions vas how they became aware of such problems and what they did when someone had problem with constipation. It also asked about their methods to prevent constipation and if they thought anything could be done better in the future. The method used was a qualitative interview study. The study included eight nurse assistants who worked in municipal nursing homes for people with dementia. The interviews where tape recorded, then written and analysed with a phenomenological method. The result illustrate how the nurse assistants used their sense for observing and their personal feelings to share the experience with the person. This gave trust and renders possibility to get knowledge and also gave opportunity to prevent problems and give help, in a way that not reduced dignity for the person. Bowel control, fluid, food and the possibility to get out for a walk was important. It was also important to have enough time for sharing reflections. Small units gave possibility to personal knowledge.

Bakgrund: Diabetes typ 2 är en folksjukdom och kan förebyggas eller fördröjas genom hälsosamma levnadsvanor. Att informera och motivera patienterna på ett hälsofrämjande och preventivt sätt är distriktssköterskans ansvar. Distriktssköterskans nyckelroll är att kritiskt granska evidensbaserad forskning för att uppnå en säker vård av god kvalitet som kan implementeras i praktiken. Syfte: Syftet med studien var att beskriva distriktssköterskors upplevelser av att motivera patienter med diabetes typ 2 till hälsosammare levnadsvanor genom evidensbaserad vård. Metod: En kvalitativ ansats användes. Semistrukturerade intervjuer genomfördes med sju distriktssköterskor. Materialet analyserades utifrån Graneheim och Lundmans innehållsanalys. Resultat: Resultatet i föreliggande studie visar att distriktssköterskorna måste utgå från patientens situation och individanpassa informationen. Genom stöd från distriktssköterskan ska patienten kunna motivera sig själv till att genomföra förändringar. Informanterna i studien belyste vikten av att informera patienten om diabetes samt vilka komplikationer som kan uppstå. För att uppnå en patientsäker vård av hög kvalitet ansåg distriktssköterskorna att evidensbaserad kunskap var en förutsättning. Konklusion: För att motivera patienterna till förändrade levnadsvanor krävs det att distriktssköterskorna informerar och undervisar patienterna om diabetes och hur förändrade levnadsvanor påverkar hälsan. Distriktssköterskan måste finna olika metoder för att motivera patienterna. Det som förmedlas ska grunda sig på vetenskap och evidensbaserad kunskap.

O aumento da concorrência exige que as empresas sejam competitivas e conheçam profundamente o ambiente do qual fazem parte. Através da busca e da análise das informações concorrenciais, as empresas poderão identificar ameaças e oportunidades do mercado, possibilitando o reconhecimento de tendências e de pistas fundamentais sobre a concorrência, o que pode conduzir a obtenção de vantagens competitivas. A área que tem se preocupado principalmente com a recuperação e o tratamento de informações do ambiente concorrencial, é denominada internacionalmente de Inteligência Competitiva (IC). Este trabalho apresenta os resultados de um estudo exploratório, sobre a busca e a análise de informações do ambiente concorrencial nas empresas da indústria moveleira da região de Bento Gonçalves do Rio Grande do Sul, visando colocar em evidência a importância dessa área para um melhor posicionamento das indústrias desse setor no mercado nacional e internacional. Os resultados alcançados com a pesquisa, apresentam diversas características sobre a indústria moveleira, tais como: centralização da informação, subutilização da Tecnologia da Informação, monitoramento restrito e informal da concorrência, entre outras. Em síntese, revelam que a grande maioria das empresas não possuem um setor específico para o monitoramento do ambiente, onde poucas empresas utilizam a Inteligência Competitiva como recurso para a análise de informações. A subdivisão da amostra em três extratos distintos permitiu identificar as características de cada extrato da amostra quanto ao conhecimento do ambiente concorrencial.

Este trabalho foi realizado com o intuito de estudar as plantas utilizadas como medicinais pelos moradores do bairro Ponta Grossa e pelos Agentes Comunitários de Saúde relacionados ao Posto de Saúde da Família do bairro Ponta Grossa, Porto Alegre, Rio Grande do Sul. Como metodologia, foram realizadas entrevistas estruturadas, na forma de questionários, para obtenção dos dados socioculturais e semi-estruturadas para o levantamento dos dados sobre as plantas. Foram coletadas 150 espécies utilizadas pela população, sendo 9 delas identificadas somente até gênero, pertencentes a 59 famílias botânicas. As famílias mais representadas em número de espécies foram Asteraceae e Lamiaceae. As partes das plantas mais utilizadas foram folhas e partes aéreas, sendo o chá a principal forma de utilização. As doenças e/ou sintomas mais mencionados foram os relacionados aos aparelhos digestório e respiratório. Em uma análise dos nomes populares foram encontradas 56 espécies com etnohomônimos e 73 espécies com etno-sinônimos verdadeiros ou falsos. Também foi realizada uma revisão bibliográfica comparativa entre as indicações de uso originais e as indicações atuais referidas no estado do Rio Grande do Sul e países limítrofes. Esta revisão teve como objetivo verificar se houve alterações do conhecimento popular. Uma espécie apresentou equivalência entre as indicações de usos originais e atuais e 140 apresentaram alteração do conhecimento popular. Para 16 espécies foi detectada alteração total do conhecimento, 61 apresentaram ampliação do conhecimento e 21 redução do conhecimento popular. Ferramentas quantitativas foram utilizadas, como Valor de Uso (UV) e a porcentagem de Concordância corrigida quanto aos Usos Principais (CUPc), para verificar quais as espécies mais importantes para a população e as mais promissoras para a realização de estudos biológicos posteriores. Para as 21 espécies mais importantes foram feitas revisões na literatura científica com o objetivo de reunir dados químicos e biológicos, que resultarão na elaboração de um manual didático, o qual será devolvido como um retorno para a população estudada.

Background: The integration of sequencing and gene interaction data and subsequent generation of pathways and networks contained in databases such as KEGG Pathway is essential for the comprehension of complex biological processes. We noticed the absence of a chart or pathway describing the well-studied preimplantation development stages; furthermore, not all genes involved in the process have entries in KEGG Orthology, important information for knowledge application with relation to other organisms. Results: In this work we sought to develop the regulatory pathway for the preimplantation development stage using text-mining tools such as Medline Ranker and PESCADOR to reveal biointeractions among the genes involved in this process. The genes present in the resulting pathway were also used as seeds for software developed by our group called SeedServer to create clusters of homologous genes. These homologues allowed the determination of the last common ancestor for each gene and revealed that the preimplantation development pathway consists of a conserved ancient core of genes with the addition of modern elements. Conclusions: The generation of regulatory pathways through text-mining tools allows the integration of data generated by several studies for a more complete visualization of complex biological processes. Using the genes in this pathway as “seeds” for the generation of clusters of homologues, the pathway can be visualized for other organisms. The clustering of homologous genes together with determination of the ancestry leads to a better understanding of the evolution of such process.

Ontology design and population -core aspects of semantic technologies- re- cently have become fields of great interest due to the increasing need of domain-specific knowledge bases that can boost the use of Semantic Web. For building such knowledge resources, the state of the art tools for ontology design require a lot of human work. Producing meaningful schemas and populating them with domain-specific data is in fact a very difficult and time-consuming task. Even more if the task consists in modelling knowledge at a web scale. The primary aim of this work is to investigate a novel and flexible method- ology for automatically learning ontology from textual data, lightening the human workload required for conceptualizing domain-specific knowledge and populating an extracted schema with real data, speeding up the whole ontology production process. Here computational linguistics plays a fundamental role, from automati- cally identifying facts from natural language and extracting frame of relations among recognized entities, to producing linked data with which extending existing knowledge bases or creating new ones. In the state of the art, automatic ontology learning systems are mainly based on plain-pipelined linguistics classifiers performing tasks such as Named Entity recognition, Entity resolution, Taxonomy and Relation extraction [11]. These approaches present some weaknesses, specially in capturing struc- tures through which the meaning of complex concepts is expressed [24]. Humans, in fact, tend to organize knowledge in well-defined patterns, which include participant entities and meaningful relations linking entities with each other. In literature, these structures have been called Semantic Frames by Fill- 6 Introduction more [20], or more recently as Knowledge Patterns [23]. Some NLP studies has recently shown the possibility of performing more accurate deep parsing with the ability of logically understanding the structure of discourse [7]. In this work, some of these technologies have been investigated and em- ployed to produce accurate ontology schemas. The long-term goal is to collect large amounts of semantically structured information from the web of crowds, through an automated process, in order to identify and investigate the cognitive patterns used by human to organize their knowledge.

This article contributes to the research on demographics and public health of urban populations of preindustrial Europe. The key source is a burial register that contains information on the deceased, such as age and sex, residence and cause of death. This register is one of the earliest compilations of data sets of individuals with this high degree of completeness and consistency. Critical assessment of the register's origin, formation and upkeep promises high validity and reliability. Between 1805 and 1815, 4,390 deceased inhabitants were registered. Information concerning these individuals provides the basis for this study. Life tables of Bern's population were created using different models. The causes of death were classified and their frequency calculated. Furthermore, the susceptibility of age groups to certain causes of death was established. Special attention was given to causes of death and mortality of newborns, infants and birth-giving women. In comparison to other cities and regions in Central Europe, Bern's mortality structure shows low rates for infants (q0=0.144) and children (q1-4=0.068). This could have simply indicated better living conditions. Life expectancy at birth was 43 years. Mortality was high in winter and spring, and decreased in summer to a low level with a short rise in August. The study of the causes of death was inhibited by difficulties in translating early 19th century nomenclature into the modern medical system. Nonetheless, death from metabolic disorders, illnesses of the respiratory system, and debilitation were the most prominent causes in Bern. Apparently, the worst killer of infants up to 12 months was the "gichteren", an obsolete German term for lethal spasmodic convulsions. The exact modern identification of this disease remains unclear. Possibilities such as infant tetanus or infant epilepsy are discussed. The maternal death rate of 0.72% is comparable with values calculated from contemporaneous sources. Relevance of childbed fever in the early 1800s was low. Bern's data indicate that the extent of deaths related to childbirth in this period is overrated. This research has an explicit interdisciplinary value for various fields including both the humanities and natural sciences, since information reported here represents the complete age and sex structure of a deceased population. Physical anthropologists can use these data as a true reference group for their palaeodemographic studies of preindustrial Central Europe of the late 18th and early 19th century. It is a call to both historians and anthropologists to use our resources to a better effect through combination of methods and exchange of knowledge.

Although powder metallurgical methods have been used for years to fabricate tungsten and platinum, very little scientific data have been recorded until the beginning of this century. A large percentage of all commercial production at present is based upon past practice rather than upon scientific knowledge.

Most desertification research focuses on degradation assessments without putting sufficient emphasis on prevention and mitigation strategies, although the concept of Sustainable Land Management (SLM) is increasingly being acknowledged. A variety of already applied conservation measures exist at the local level, but they are not adequately recognised, evaluated and shared, either by land users, technicians, researchers, or policy makers. Likewise, collaboration between research and implementation is often insufficient. The aim of this paper is to present a new methodology for a participatory process of appraising and selecting desertification mitigation strategies, and to present first experiences from its application in the EU-funded DESIRE project. The methodology combines a collective learning and decision approach with the use of evaluated global best practices. In three parts, it moves through a concise process, starting with identifying land degradation and locally applied solutions in a stakeholder workshop, leading to assessing local solutions with a standardised evaluation tool, and ending with jointly selecting promising strategies for implementation with the help of a decision support tool. The methodology is currently being applied in 16 study sites. Preliminary analysis from the application of the first part of the methodology shows that the initial stakeholder workshop results in a good basis for stakeholder cooperation, and in promising land conservation practices for further assessment. Study site research teams appreciated the valuable results, as burning issues and promising options emerged from joint reflection. The methodology is suitable to initiate mutual learning among different stakeholder groups and to integrate local and scientific knowledge.

Competing water demands for household consumption as well as the production of food, energy, and other uses pose challenges for water supply and sustainable development in many parts of the world. Designing creative strategies and learning processes for sustainable water governance is thus of prime importance. While this need is uncontested, suitable approaches still have to be found. In this article we present and evaluate a conceptual approach to scenario building aimed at transdisciplinary learning for sustainable water governance. The approach combines normative, explorative, and participatory scenario elements. This combination allows for adequate consideration of stakeholders’ and scientists’ systems, target, and transformation knowledge. Application of the approach in the MontanAqua project in the Swiss Alps confirmed its high potential for co-producing new knowledge and establishing a meaningful and deliberative dialogue between all actors involved. The iterative and combined approach ensured that stakeholders’ knowledge was adequately captured, fed into scientific analysis, and brought back to stakeholders in several cycles, thereby facilitating learning and co-production of new knowledge relevant for both stakeholders and scientists. However, the approach also revealed a number of constraints, including the enormous flexibility required of stakeholders and scientists in order for them to truly engage in the co-production of new knowledge. Overall, the study showed that shifts from strategic to communicative action are possible in an environment of mutual trust. This ultimately depends on creating conditions of interaction that place scientists’ and stakeholders’ knowledge on an equal footing.

This paper considers ocean fisheries as complex adaptive systems and addresses the question of how human institutions might be best matched to their structure and function. Ocean ecosystems operate at multiple scales, but the management of fisheries tends to be aimed at a single species considered at a single broad scale. The paper argues that this mismatch of ecological and management scale makes it difficult to address the fine-scale aspects of ocean ecosystems, and leads to fishing rights and strategies that tend to erode the underlying structure of populations and the system itself. A successful transition to ecosystem-based management will require institutions better able to economize on the acquisition of feedback about the impact of human activities. This is likely to be achieved by multiscale institutions whose organization mirrors the spatial organization of the ecosystem and whose communications occur through a polycentric network. Better feedback will allow the exploration of fine-scale science and the employment of fine-scale fishing restraints, better adapted to the behavior of fish and habitat. The scale and scope of individual fishing rights also needs to be congruent with the spatial structure of the ecosystem. Place-based rights can be expected to create a longer private planning horizon as well as stronger incentives for the private and public acquisition of system relevant knowledge.

Este artículo analiza los alcances de la expresión "observación participante" como técnica etnográfica de recolección de datos. A través de los materiales consignados por escrito correspondientes a una investigación concreta, se ponen de relieve las distintas actividades que la antropóloga social argentina Esther Hermitte desarrolló en los Altos de Chiapas en 1960-1, y que culminaron con el descubrimiento de un sistema de gobierno sobrenatural. Estas actividades, que aparecen como complementarias y hasta periféricas de las verdaderas técnicas (entrevistas, cuestionarios, encuestas) de la investigación propiamente dicha, dan sentido a la "observación participante" como Instrumento que permite familiarizar a la investigadora con los contextos que dan sentido a cuanto ocurre en ellos, y configurar el lugar de la investigadora al modo que lo hacen los tzeltales de Pinola, sus sujetos de estudio. La observación participante, entonces, bandona el ámbito de las "técnicas" concebidas unilateralmente desde el medio académico, para constituir una expresión en que los lugareños y sus investigadores negocian los términos de su relación y, al hacerlo, producen (mutuos) comprensión y conocimiento

El artículo busca analizar el lugar de Víctor Mercante en la producción de un discurso científico sobre la educación, sobre todo con las asociaciones discursivas entre ciencia y pedagogía y entre pedagogía científica y reforma educativa. Partiendo de una revisión de las lecturas historiográficas sobre su obra, el texto se detiene en el proyecto epistémico-político de la Paidología como ciencia de la infancia escolarizada y del Laboratorio en la Universidad de La Plata como institución de producción y diseminación de saberes. Mercante se estableció firmemente en redes internacionales de conocimiento y sostuvo la idea de la ciencia como empresa cosmopolita de saber, ciencia que debía ser escrita con números, cuadros y citas a pie de página como criterio de legitimidad de sus enunciados. Finalmente, se destaca su importancia en el privilegio de la infancia y la adolescencia como sujetos pedagógicos, todavía apegados a categorías epistémico-políticas del siglo XIX pero enunciados con instrumentos, lenguajes y redes de saberes del siglo XX
