A Harmonized Vocabulary For Water Quality

Interoperability of water quality data depends on the use of common models, schemas and vocabularies. However, terms are usually collected during different activities and projects in isolation of one another, resulting in vocabularies that have the same scope being represented with different terms, using different formats and formalisms, and published in various access methods. Significantly, most water quality vocabularies conflate multiple concepts in a single term, e.g. quantity kind, units of measure, substance or taxon, medium and procedure. This bundles information associated with separate elements from the OGC Observations and Measurements (O&M) model into a single slot. We have developed a water quality vocabulary, formalized using RDF, and published as Linked Data. The terms were extracted from existing water quality vocabularies. The observable property model is inspired by O&M but aligned with existing ontologies. The core is an OWL ontology that extends the QUDT ontology for Unit and QuantityKind definitions. We add classes to generalize the QuantityKind model, and properties for explicit description of the conflated concepts. The key elements are defined to be sub-classes or sub-properties of SKOS elements, which enables a SKOS view to be published through standard vocabulary APIs, alongside the full view. QUDT terms are re-used where possible, supplemented with additional Unit and QuantityKind entries required for water quality. Along with items from separate vocabularies developed for objects, media, and procedures, these are linked into definitions in the actual observable property vocabulary. Definitions of objects related to chemical substances are linked to items from the Chemical Entities of Biological Interest (ChEBI) ontology. Mappings to other vocabularies, such as DBPedia, are in separately maintained files. By formalizing the model for observable properties, and clearly labelling the separate concerns, water quality observations from different sources may be more easily merged and also transformed to O&M for cross-domain applications.

Ampliando futuros: o curso pré-vestibular comunitário da Maré

Estudo sobre o Curso Pré-vestibular Comunitário da Maré (CPV Maré), a partir de sua inserção no movimento de pré-vestibulares comunitários existente hoje em todo o Brasil. Os dados e fontes coletados permitiram entender como se deu a trajetória do curso, bem como seus resultados e limites. Através do crescimento do curso, é possível entender o processo de crescimento e institucionalização do Centro de Estudos e Ações Solidárias da Maré (CEASM), organização não governamental criada por moradores e ex-moradores da Maré em 1997, que teve crescente e expressivo crescimento desde a sua formação. Em sete anos de existência - 1998 a 2005 -, os estudantes que freqüentaram o CPV Maré obtiveram, ao todo, 539 aprovações para universidades públicas e privadas, sobretudo para a PUC-RJ, totalizando 408 ingressos de alunos no ensino superior. Em consonância com a proposta do curso, e diante da condição econômica de seus alunos, serão aqui consideradas apenas as aprovações para as universidades públicas e para a PUC RJ, tendo em vista a parceria estabelecida entre essa universidade e o CEASM, no tocante à concessão de bolsas de estudo. Assim, são 355 alunos que ingressaram nas universidades públicas e na PUC-Rio. È com esse quantitativo que iremos trabalhar neste estudo.

Isomorfismo e cerimonialismo em gestão empresarial: pesquisa empírica sobre a difusão de certificações ISO-9000 no Brasil

Esta pesquisa analisa a difusão das certificações ISO-9000 no Brasil sob o prisma da teoria neo-institucional e de referências sobre modismos gerenciais nas organizações. A premissa é de que muitas dessas decisões de certificação - que se tornou muito popular nas empresas brasileiras desde 1990 - só podem ser entendidas plenamente à luz de sua natureza modal e institucionalizada, e que muitas desses processos podem refletir adoções cerimoniais (isto é "para inglês ver"). Através de questionários aplicados em empresas que buscaram a certificação ISO no Brasil, o estudo procura entender melhor fatores ligados à tomada de decisão sobre a adoção, à estratégia de implantação, aos resultados percebidos e aos mecanismos de justificação dos programas.

Três ensaios sobre o mercado de trabalho no Brasil

Esta tese é composta por três artigos e uma nota, sendo um em cada capítulo. Todos os capítulos enquadram-se na área de Microeconomia Aplicada e Economia do Trabalho. O primeiro artigo estende o modelo tradicional de decomposição das flutuações na taxa de desemprego de Shimer (2012), separando o emprego formal do informal. Com essa modificação, os principais resultados da metodologia se alteram e conclui-se que os principais fatores para a queda do desemprego na última década foram (i) a queda na taxa de participação, principalmente pela menor entrada na força de trabalho; (ii) o aumento da formalização, atingido tanto pelo aumento da probabilidade de encontrar um trabalho formal quanto pela probabilidade de deixar a condição de empregado formal. O segundo capítulo apresenta estimativas para o retorno à educação no Brasil, utilizando uma nova metodologia que não necessita de variáveis de exclusão. A vantagem do método em relação a abordagens que utilizam variáveis instrumentais é a de permitir avaliar o retorno médio para todos os trabalhadores (e não somente os afetados pelos instrumentos) e em qualquer instante do tempo. Face aos resultados, concluímos as estimativas via MQO subestimam o retorno médio. Discute-se possíveis explicações para esse fenômeno. O terceiro artigo trata da terceirização da mão de obra no Brasil. Mais especificamente, mede-se o diferencial de salários entre os trabalhadores terceirizados e os contratados diretamente. Os resultados de uma comparação não condicional indicam que os terceirizados têm salário médio 17% menor no período 2007 a 2012. Porém, com estimativas que levam em conta o efeito fixo de cada trabalhador, esse diferencial cai para 3,0%. Além disso, o diferencial é bastante heterogêneo entre os tipos de serviços: aqueles que utilizam trabalhadores de baixa qualificação apresentam salário menores, enquanto nas ocupações de maior qualificação os terceirizados têm salários iguais ou maiores do que os diretamente contratados. Mais ainda, as evidencias apontam para a diminuição do diferencial ao longo do tempo no período analisado. Finalmente, a nota que encerra a tese documenta dois aspectos relevantes e pouco conhecidos da Pesquisa Mensal de Emprego do IBGE que podem levar a resultados imprecisos nas pesquisas que utilizam esse painel se não forem tratados adequadamente.

Gestão de capital de giro na internacionalização das empresa : uma análise comparativa entre empresas locais e multinacionais

O objetivo desta pesquisa é testar empiricamente se a gestão de capital de giro adotada pelas empresas multinacionais em outros países se altera na internacionalização em países complexos como o Brasil. Baseado nas respostas a um questionário obtido de uma amostra de 182 empresas do setor eletroeletrônico, elétrico, e de máquinas e equipamentos do Brasil, testes foram conduzidos para encontrar correlação na decisão de uso de cessão de direitos creditórios com a distância psíquica e o tempo de experiência dessas empresas no Brasil. Resultados apontam a maior propensão no uso de cessão de direitos creditórios como ferramenta alternativa de financiamento de curto prazo pelas empresas multinacionais sediadas em países mais distantes psiquicamente e com menor tempo de experiência no Brasil. Estudos sobre finanças internacionais indicam que uma maior distância psíquica das empresas multinacionais aumenta a aversão a incertezas e riscos, e, logo, a necessidade de manutenção de maiores níveis de caixa. Dependendo do tempo de experiência das empresas no mercado estrangeiro, a distância psíquica pode ser minimizada por meio de um processo de aprendizagem organizacional.

Sheaves, local homeomorphisms and local sets as Hilbert locale modules

We give a thorough account of the various equivalent notions for \sheaf" on a locale, namely the separated and complete presheaves, the local home- omorphisms, and the local sets, and to provide a new approach based on quantale modules whereby we see that sheaves can be identi¯ed with certain Hilbert modules in the sense of Paseka. This formulation provides us with an interesting category that has immediate meaningful relations to those of sheaves, local homeomorphisms and local sets. The concept of B-set (local set over the locale B) present in [3] is seen as a simetric idempotent matrix with entries on B, and a map of B-sets as de¯ned in [8] is shown to be also a matrix satisfying some conditions. This gives us useful tools that permit the algebraic manipulation of B-sets. The main result is to show that the existing notions of \sheaf" on a locale B are also equivalent to a new concept what we call a Hilbert module with an Hilbert base. These modules are the projective modules since they are the image of a free module by a idempotent automorphism On the ¯rst chapter, we recall some well known results about partially ordered sets and lattices. On chapter two we introduce the category of Sup-lattices, and the cate- gory of locales, Loc. We describe the adjunction between this category and the category Top of topological spaces whose restriction to spacial locales give us a duality between this category and the category of sober spaces. We ¯nish this chapter with the de¯nitions of module over a quantale and Hilbert Module. Chapter three concerns with various equivalent notions namely: sheaves of sets, local homeomorphisms and local sets (projection matrices with entries on a locale). We ¯nish giving a direct algebraic proof that each local set is isomorphic to a complete local set, whose rows correspond to the singletons. On chapter four we de¯ne B-locale, study open maps and local homeo- morphims. The main new result is on the ¯fth chapter where we de¯ne the Hilbert modules and Hilbert modules with an Hilbert and show this latter concept is equivalent to the previous notions of sheaf over a locale.

Desenho e implementação da presença web do Rali Vinho da Madeira

A promoção de qualquer evento passa, em muito, pela utilização da Internet como meio de disponibilização e propagação de conteúdos, através de um website ou de redes sociais. Mas não é só para a disponibilização de conteúdos que estes websites são úteis. A adição de funcionalidades permite torná-los em plataformas mais completas e com os mais diversos propósitos, incluindo elementos para a gestão do próprio evento. Este projeto surge da necessidade da organização do Rali Vinho Madeira (RVM) em substituir a plataforma existente, insuficiente para as necessidades atuais na área da divulgação pública do evento e na gestão das inscrições e registo de diversas entidades participantes no evento. Assim, o objetivo principal deste projeto passou pelo desenvolvimento de um novo website que implementasse os requisitos de forma satisfatória tanto para a organização do RVM como para os utilizadores. Ao mesmo tempo foi também importante garantir que o servidor onde estaria alojada a nova plataforma possuiria o melhor desempenho possível em condições reais, usando para o efeito um plano de testes de carga para validar as configurações escolhidas e detetar atempadamente possíveis problemas. Um último componente da plataforma do RVM, desenvolvido ainda no âmbito deste trabalho, foi o desenvolvimento de uma aplicação web para consulta dos resultados em equipamentos mobile, como smartphones e tablet’s. Ao longo deste documento são descritas as várias etapas do projeto, de onde se destacam: (1) a avaliação de websites para melhorar a caracterização dos requisitos, (2) o processo de análise, especificação e desenvolvimento da plataforma, e (3) a realização de testes de carga como meio de validação das configurações do servidor para um desempenho satisfatório durante a prova. O módulo Rally Entries, central para a organização e também para este projeto, transforma uma plataforma simples de disponibilização de conteúdos num sistema para gestão das inscrições de diversas entidades no âmbito do RVM. Além da descrição da implementação e das funcionalidades deste módulo, é ainda descrita a forma como este componente será capaz de se adaptar a novos requisitos em futuros eventos. A validação da plataforma desenvolvida passou por um contato com os utilizadores através de inquéritos. No geral os resultados obtidos foram positivos, comparativamente à plataforma existente e a websites de outros ralis. Como evento integrante das atividades da Federação Internacional do Automóvel (FIA) e da Federação Portuguesa de Automobilismo e Karting, o website também integrou a avaliação do evento feito por estas organizações, tendo recebido em ambas as avaliações 4 pontos em 5 possíveis. Por último, os testes de carga realizados revelaram ser uma grande ajuda na preparação da plataforma, principalmente para os períodos de pico de acessos, tendo esta sido capaz de responder de forma previsível à carga a que foi sujeita.

A Cabana Umbamdista Pai Joaquim de Angola: frente a intolerância a Umbanda na Cidade do Natal/RN

This dissertation presents an attempt to register the initial steps of african-Brazilian religion Umbanda in the city of Natal, capital of Rio Grande do Norte, from a case study of Cabana Umbanda Pai Joaquim de Angola, represented by its maintainer, umbanda of the priest José Clementino. The main objective is to record the memories of fans in aspects of its tradition, experience social and cultural religious building, in an attempt to show the religious hatred with practitioners of Umbanda. Used to: in audio recordings of festivals and rituals, narratives about the memories and stories of employees and their explanations, photographs, diary entries in the field, participant observation and interviews available. The analysis referred to in umbanda Natal / RN, was based on field research as a product of the visits that took place between the years 2006 to 2009 in Terreiro de Umbanda Pai Joaquim de Angola, located in the neighborhood of Rocas.

Vocabulário técnico e formação dos profissionais da área têxtil: necessidade, elaboração e avaliação de um dicionário de terminologia do vestuário

This research work deals with the compilation of a dictionary on clothing terminology intended to be used as a pedagogic tool as part of the teaching and learning process in the Textile Engineering Course at the Federal University of Rio Grande do Norte. The main terms were selected and assessed by a team of textile teachers and students with the objective to be structured as a conceptual body of information on the following sub-areas of clothing terminology: materials (fabrics and trimmings) and products (garments). This research comprises three main steps: (a) characterization and understanding of the technical vocabulary in the clothing area as well as the identification of a pedagogic demand for a dictionary on clothing terminology, clearly expressed by the textile lecturers and students involved in the assessment of the need and validation of this project development; (b) a proposal for a specific methodology for the compilation of the dictionary which could help the communication process in the lecturing of clothing terminology and (c) based on the terminological principles and the technique of focal groups the dictionary was assessed. The technique of focal groups was used in the first step. In the second step the technique used was that of the terminological methodology adapted to the teaching approach in the Textile Course. In the third step the technique of focal groups was again utilized. It was observed that the main concern of lecturers and students is the lack of a standardized vocabulary, which renders difficult the communication process in both the teaching and learning activities as well as the professional ones in the textile industries. Various aspects, which can overlap, cause this lack of standardization. The main ones pointed out by the study team in the focal groups are: usage of regional words or expressions, usage of foreign words or expressions, analogies, and the low level of formal education, mainly among the industry workers. Another aspect to be considered is the lack of textile literature written in the Portuguese language of Brazil. This evidence shows the importance of a clothing terminology dictionary which will benefit both the education and professional activties in this field of knowledge. This dictionary will also give a substantial contribution to terminological standardization in our research field. With view to fulfill this demand, a dictionary of clothing terminology was compiled with 760 main entries, according to the modern practice in terminology with the necessary modifications concerning our needs. The result of the dictionary assessment was very assertive regarding its structure, contents and possible use in various contexts. The team work emphasized their contribution to the standardization process of the terms that proved to be one of the most important and difficult aspects of this researh work. The significance of this structured terminological dictionary was confirmed by the focal group participants relating to its use for teaching and learning activities, as a reference book, as a source of technical information and also as a tool for pedagogic studies and planning, as well as a significant collaboration to the pedagogic practices in the textile engineering course at University or any other educational institution. Besides, this dictionary can also be used to supply information within the textile field. We are aware that the present work will not exhaust the objectives of this research due to its limitations in opposition to the vast complexity demanded by the compilation of a complete work including all the areas and sub-areas of textile engineering. However, it is an important source for dissemination of concepts on the field of clothing terminology and a tool to effective standardization of the terms used in this subject field

Processo de alimentação do Sistema de Informação do HiperDia: Estudo de Caso no município de Natal/RN

Although the records indicate the involvement of the City Christmas in the feeding system HiperDia, a survey conducted by the Health Ministry in 2004 found that the number of entries made in Natal was well below estimate. In order to understand the functioning of HiperDia, we performed this study to analyze the actions taken by the professionals involved in power system HiperDia in Natal / RN. The research has developed into a quantitative perspective, with the design of exploratory case study conducted in the health services that integrate the various levels of the organization who are directly involved with the process of system power HiperDia in Natal / RN , represented here by SMS, health districts and the Family Health Units in the period from August to October 2008.Study participants were 110 professionals, including nurses, physicians, operators, administrator and a coordinator. The survey results showed that feeding HiperDia in Natal was maintained mainly by health professionals and operators. Activities include carrying out the state registration, monitoring, and updating of data transfer routines. They report that the difficulties in the process of feeding data are related to the work of teams and / or lack of structure of the Program of Hypertension and Diabetes (HA and DM), the discontinuity of federal investments in improving the HiperDia and lack of training. We can see then that the process of feeding system on Christmas HiperDia therefore is developing the three levels (SMS, districts and health units), however is not matching the expectations established by MS, considering that the gaps the flow of information are undermining the end result of this process

Identificação fuzzy-multimodelos para sistemas não lineares

This paper presents a new multi-model technique of dentification in ANFIS for nonlinear systems. In this technique, the structure used is of the fuzzy Takagi-Sugeno of which the consequences are local linear models that represent the system of different points of operation and the precursors are membership functions whose adjustments are realized by the learning phase of the neuro-fuzzy ANFIS technique. The models that represent the system at different points of the operation can be found with linearization techniques like, for example, the Least Squares method that is robust against sounds and of simple application. The fuzzy system is responsible for informing the proportion of each model that should be utilized, using the membership functions. The membership functions can be adjusted by ANFIS with the use of neural network algorithms, like the back propagation error type, in such a way that the models found for each area are correctly interpolated and define an action of each model for possible entries into the system. In multi-models, the definition of action of models is known as metrics and, since this paper is based on ANFIS, it shall be denominated in ANFIS metrics. This way, ANFIS metrics is utilized to interpolate various models, composing a system to be identified. Differing from the traditional ANFIS, the created technique necessarily represents the system in various well defined regions by unaltered models whose pondered activation as per the membership functions. The selection of regions for the application of the Least Squares method is realized manually from the graphic analysis of the system behavior or from the physical characteristics of the plant. This selection serves as a base to initiate the linear model defining technique and generating the initial configuration of the membership functions. The experiments are conducted in a teaching tank, with multiple sections, designed and created to show the characteristics of the technique. The results from this tank illustrate the performance reached by the technique in task of identifying, utilizing configurations of ANFIS, comparing the developed technique with various models of simple metrics and comparing with the NNARX technique, also adapted to identification

Longitudinal study of daily variation of rats' behavior in the elevated plus-maze

We conducted a longitudinal study about daily variation of Wistar male rats' behavior in the elevated plus-maze (EPM) evaluated in the 1st, 2nd, 3rd, 6th, 12th, and 18th months of life. Animals were submitted to the plus-maze in 12 sessions at 2-h intervals (n=72, 6 per time point). Spontaneous rest-activity rhythm of four animals was assessed by observation of 24-h videotape records. Time series were analyzed by Cosinor method. Behavioral rates on the six occasions and in light and dark phases were compared by means of two-way ANOVA with repeated measures. Exploratory behavior in EPM was smaller in the light phase and in older animals. Higher values of open and closed arms exploration were observed in the first and third months of the dark phase, and in the first month of the light phase. Adjustment to the 24-h period was significant at all stages for rest-activity data, number of entries in closed arms, and time on center, and for three to five stages for open-arm exploration. In general, 24 h variability was more pronounced in younger animals compared with older ones. The present study showed that: (1) a significant amount of total variability of the behavioral indexes analyzed could be attributed to 24 h variation, (2) light/dark phases differences in EPM exploration were present at all developmental stages, (3) older Wistar rats explored less the EPM and were less active in their home cage compared with younger ones, and (4) behavioral indexes (EPM) decrease was phase related and partially related to a reorganization of rest-activity rhythm.

Anxiety-induced antinociception in mice: effects of systemic and intra-amygdala administration of 8-OH-DPAT and midazolam

Rationale: Mice exhibit antinociception after a single experience in the elevated plus maze (EPM), an animal model of anxiety. Objective: This study investigated the mechanisms involved in this form of anxiety-induced antinociception. Methods: Nociception was evaluated by means of the writhing test in mice confined either to the open or enclosed arms of the EPM. The effects of systemic (naloxone, midazolam and 8-OH-DPAT) or intra-amygdala (8-OH-DPAT. NAN-190 and midazolam) drug infusions were investigated in mice previously treated i.p. with 0.6% acetic acid, an algic stimulus that induces abdominal contortions. The effects of these drugs on conventional measures of anxiety (% entries and % time in open arms) in a standard EPM test were also independently investigated. Results: Open-arm confinement resulted in a high-magnitude antinociception (minimum 85%, maximum 450%) compared with enclosed arm confinement. The opiate antagonist naloxone (1 mg/kg and 10 mg/kg) neither blocked this open arm-induced antinociception (OAIA) nor modified indices of anxiety in EPM. Administration of midazolam (0.5-2 mg/kg, s.c.) increased OAIA and produced antinociception in enclosed confined animals, as well as attenuating anxiety in the EPM. The 5-HT(1A) receptor agonist 8-OH-DPAT (0.05-1 mg/kg, s.c.) had biphasic effects on OAIA, antagonising the response at the lowest dose and intensifying it at the highest dose. In addition, low doses of this agent reduced anxiety in the EPM. Although bilateral injections of 8-OH-DPAT (5.6 nmol/0.4 mu l) or NAN-190 (5.6 nmol and 10 nmol/0.4 mu l) into the amygdala did not alter OAIA, increased anxiety was observed in the EPM. In contrast, intra-amygdala administration of midazolam (10 nmol and 30 nmol/0.4 mu l) blocked both OAIA and anxiety. Conclusions: These results with systemic and intracerebral drug infusion suggest that 5-HT(1A) receptors localised in the amygdala are not involved in the pain inhibitory processes that are recruited during aversive situations. However, activation of these receptors does phasically increase anxiety. Although the intrinsic antinociceptive properties of systemically administered midazolam confounded interpretation of its effects on OAIA, intra-amygdala injections of this compound suggest that benzodiazepine receptors in this brain region modulate both the antinociceptive and behavioural (anxiety) responses to the EPM.
