As redes elétricas inteligentes significam um novo paradigma de fornecimento de energia, cuja concepção integra várias áreas de concentração, novas funcionalidades e funções até então não realizáveis, bem como uma pluralidade de tecnologias e a necessidade de infraestrutura de apoio para a sua realização. A transição das redes elétricas atuais para o modelo de rede inteligente constitui-se num processo complexo, que envolve aspectos técnicos, econômicos, regulatórios e sociológicos. Esta pesquisa visa contribuir significativamente para a solução dessa questão pela proposição das bases conceituais para realizar efetivamente um plano de implementação, respeitando condições vigentes e impostas por cenários de outros setores. O modelo proposto, centrado na expansão da automação, lança as bases para a análise dos impactos da rede elétrica inteligente, para a formulação, análise e seleção de alternativas de implementação. É introduzido o conceito e forma de avaliação de uma rede por meio da definição de um índice de inteligência de uma rede elétrica, composto de vários indicadores, de forma a expressar padrões de eficiência energética e operativa, aspectos de gestão de ativos e da qualidade do serviço. A proposta de alternativas para evolução da automação se baseia em um conjunto de funções pré-estabelecidas...

Esta tese se concentra sobre os debates referentes à relação entre as construções locativas, existenciais e possessivas nas línguas do mundo, dando especial atenção para o caso particular das línguas bantas, para as quais o entendimento mais completo da relação entre aquelas construções só se dá se o domínio conceitual do comitativo for levado em conta. A tese se desenvolve na linha de três grandes questionamentos, que constituem três partes. A primeira se ocupa de questões referentes ao trabalho de campo ou o campo da pesquisa, o da descrição de línguas africanas no Brasil, nesse caso, o de uma linguística africana na Diáspora. São apresentados os principais aspectos gramaticais das línguas do estudo, com ênfase das línguas bantas das zonas H, K e R, englobando assim todo o território de Angola. A segunda parte trata das questões teóricas, apresentando as diversas propostas que almejaram analisar as construções possessivas e outras a elas relacionadas, sendo classificadas em duas: (i) as propostas localistas, para as quais o domínio de possessivos e existenciais são em última instância locativos; e (ii) as propostas não localistas, que buscaram identificar outros fatores na relação de possessivos e as demais construções. Apresentam-se também os questionamentos epistemológicos seguindo as reflexões de um anarquismo epistemológico em linguística. Partindo dos pressupostos da Gramática Cognitiva...

O modelo centro-periferia de Edward Shils é apresentado como base conceitual para a identificação de variáveis significativas no estudo da comunicação da ciência brasileira. O modelo original é uma visão da estrutura das sociedades, bastante difundida nas décadas de 60 e 70, na qual se percebe um centro e zonas periféricas, físicas ou metafóricas e identifica graus de distância que separam essas zonas do centro. Argumenta-se que a estrutura percebida por Shils pode ainda ser útil para identificar relações no mundo científico e fatores que as influenciam, especialmente no sistema de publicações periódicas, onde ainda prevalecem as características identificadas por aquele autor: a existência de um centro que concentra o poder e que estabelece um sistema de valores reconhecido e adotado por consenso (ainda que não total) pelos chamados países periféricos. As relações entre a zona central e periferias descritas no modelo podem ser identificadas na ciência como um todo, em campos de estudo específicos, em especialidades dentro de um campo e em grupos de pesquisadores. __________________________________________________________________________________ ABSTRACT; The so called centre-periphery schema proposed by Edward Shils in the late 60’s is presented as a conceptual basis for the identification of variables acting upon Brazilian scientific communication today. The original schema perceives the structure of all human societies as composed of a physical or metaphorical core and peripheral regions and identifies degrees of distance from these to the core. The argument of the article is that such schema may be very useful today...

A Entidade Reguladora para a Comunicação Social (ERC) é o organismo responsável pela regulação dos meios de comunicação social em Portugal e foi criada em 2005 por lei da Assembleia da República, sendo a única entidade reguladora com abrigo constitucional. O presente relatório insere-se no quadro do estágio no projecto de investigação “A Regulação para os Media em Portugal: O Caso da ERC” (PTDC/CCI-COM/104634/2008) e visa procurar compreender – e ajudar a compreender – a ERC. Por conseguinte, o trabalho desenvolvido tem por base três dimensões: uma perspectiva histórica, uma perspectiva conceptual e uma perspectiva performativa. Em primeiro lugar, tecemos algumas considerações sobre os fundamentos da (hetero)regulação, de forma a percebermos que valores e princípios estão associados a ela, nomeadamente os imperativos de interesse público, de diversidade de acesso e conteúdo aos media e de garantia dos direitos dos cidadãos. Além disso, procuramos perscrutar diferentes entendimentos acerca do tema. É neste contexto que encontramos a perspectiva descentrada de regulação proposta por Julia Black (2002) e, num pólo contrário, uma lógica de comando e controlo, com base em argumentos de que a regulação é um mecanismo de supervisão e controlo utilizado pelo Estado face ao desempenho dos actores exteriores ao mesmo...

The rural spaces in Europe are undergoing complex processes of transition, at multiple scales, and rhythms. In order to grasp and understand the changes occurring, the need emerges for new, conceptual approaches that make it possible to combine the different factors that shape spaces. Recent, literature on the multifunctional character of rural spaces and their transition pathways shows the, need for spatially based approaches, where the natural characteristics of a landscape are combined, with the socio-economic and cultural drivers that affect its changes. Experience shows how practical, questions on the changes affecting the rural, addressed by society to the scientific community, are of a, new character and require novel research approaches. This paper argues that landscape based, approaches can be useful basis for the required conceptual innovation. The paper presents and, discusses a set of examples of practice driven research developments, in contrasting regions of Europe. And it proposes a conceptual model which aims to contextualize empirical research driven by, problems set up in practice, and combining the ecological and structural dimensions with the socioeconomic, and cultural ones, all converging in the rural landscape...

Tese de Mestrado em Design de Produto; Ao longo das últimas duas décadas tem-se registado um acréscimo significativo no número de designers envolvidos numa prática que se aproxima da arte conceptual. A pertinência desta abordagem observa-se na discussão sobre o afastamento do design de produto da cultura de consumo, aproximando-se como referido inicialmente, de uma intenção artística, inclusive no jogo (intelectual) entre conceitos e práticas. O presente estudo pretende definir o conceito de design conceptual, dotando-o de uma base teórica de suporte à prática. É, portanto, a nossa intenção principal, clarificar o conceito de design conceptual, mapeando a originalidade desta abordagem, o que, por sua vez, permitirá elencar um conjunto de premissas orientadoras do processo criativo, distanciando-o do processo "clássico" de design e enfantizando a sua ligação à intencionalaidade artística. A metodologia de investigação adoptada permitiu construir o estado da arte, cruzando a crítica literária com entrevistas a designers portugueses e com a observação empírica de alguns projectos dos designers entrevistados. Os resultados do nosso estudo confirmaram a nossa hipótese e preencheram os objectivos inicialmente traçados. Ao verificarmos a aplicação do conceito na prática profissional de alguns designers...

One important function of categories is to permit rich inductive inferences. Prior work shows that children use category labels to guide their inductive inferences. However, there are competing theories to explain this phenomenon, differing in the roles attributed to conceptual information versus perceptual similarity. Seven experiments with 4- to 5-year-old children and adults (N = 344) test these theories by teaching categories for which category membership and perceptual similarity are in conflict, and varying the conceptual basis of the novel categories. Results indicate that for non-natural kind categories that have little conceptual coherence, children make inferences based on perceptual similarity, whereas adults make inferences based on category membership. In contrast, for basic- and ontological-level categories that have a principled conceptual basis, children and adults alike make use of category membership more than perceptual similarity as the basis of their inferences. These findings provide evidence in favor of the role of conceptual information in preschoolers’ inferences, and further demonstrate that labeled categories are not all equivalent; they differ in their inductive potential.

The use of function has been recognized as an important part of the design process over last two decades, especially at the conceptual design stage, due to its critical role in determining the final product’s functionality. Although there are now some general methodologies dealing with functions or reasoning about functions, virtually no commercial CAD system can support conceptual design process due to their focus on geometrical modeling but not functional modeling. This paper presents a functional modeling approach to guide conceptual die design through functional reasoning steps including functional decomposition, functional supportive synthesis and function-structure mapping. The formed functional model provides a good basis to generate various die structures at the conceptual design stage, because function is a higher level of abstraction than structure, and helps to capture the designer’s intent. The functional modeling process has been implemented in a computerized design environment to expedite the conceptual die design process.; Singapore-MIT Alliance (SMA)

This report describes the organization and content of lexical information required for the task of machine translation. In particular, the lexical-conceptual basis for UNITRAN, an implemented machine translation system, will be described. UNITRAN uses an underlying form called lexical conceptual structure to perform lexical selection and syntactic realization. Lexical word entries have two levels of description: the first is an underlying lexical-semantic representation that is derived from hierarchically organized primitives, and the second is a mapping from this representation to a corresponding syntactic structure. The interaction of these two levels will be discussed and the lexical selection and syntactic realization processes will be described.

Performance and manufacturability are two important issues that must be taken into account during MEMS design. Existing MEMS design models or systems follow a process-driven design paradigm, that is, design starts from the specification of process sequence or the customization of foundry-ready process template. There has been essentially no methodology or model that supports generic, high-level design synthesis for MEMS conceptual design. As a result, there lacks a basis for specifying the initial process sequences. To address this problem, this paper proposes a performance-driven, microfabrication-oriented methodology for MEMS conceptual design. A unified behaviour representation method is proposed which incorporates information of both physical interactions and chemical/biological/other reactions. Based on this method, a behavioural process based design synthesis model is proposed, which exploits multidisciplinary phenomena for design solutions, including both the structural components and their configuration for the MEMS device, as well as the necessary substances for the chemical/biological/other reactions. The model supports both forward and backward synthetic search for suitable phenomena. To ensure manufacturability, a strategy of using microfabrication-oriented phenomena as design knowledge is proposed...

RESUMEN. Con la adopción del resultado global (comprehensive income) a partir de la década de los noventa del siglo XX por los organismos emisores de normas contables más relevantes en el concierto mundial, entre los que cabe destacar el International Accounting Standards Board (iasb) y el Financial Accounting Standards Board (fasb), estamos asistiendo a un posicionamiento a favor del enfoque del excedente limpio. Como consecuencia el resultado empresarial queda más vinculado a las oscilaciones de los precios de los títulos y a los tipos de cambio, frente al enfoque del excedente sucio que nos lleva a la determinación del mismo desde una óptica más restrictiva y, por ello, mucho menos conectado con la realidad de los mercados. En este trabajo nos planteamos como primer objetivo el estudio desde una óptica histórica y conceptual del antiguo y controvertido debate del enfoque del excedente limpio versus el enfoque del excedente sucio, circunscrito esencialmente a los países del área de influencia anglosajona. Posteriormente, queremos constatar que con la revisión de la Norma Internacional de Contabilidad 1 (nic 1) del International Accounting Standards Board (iasb) en el año 2007 cobra más fuerza el resultado global; con ello se confirman los planteamientos a favor del enfoque del excedente limpio...

Sustainability is central to the policy objectives of the European Commission (EC), but a widely accepted integrated sustainability assessment framework in support of policy analysis and development is currently lacking. Here, we describe the conceptual basis for the proposed European Sustainability Footprint (ESF) - an integrated sustainability assessment framework for establishing a baseline and tracking trends with respect to the sustainability of European production and consumption. This includes scenario modelling the potential impacts of EC policy alternatives. Specifically, the European Sustainability Footprint will be comprised of a selection of life-cycle based indicators (environmental, social, and economic) which can be assessed against defined sustainability targets and thresholds.; JRC.H.8-Sustainability Assessment

The author analyzes how changes in thinking about the role trade plays in economic development have been reflected in provisions affecting developing countries in the GATT and the WTO. He focuses on the provisions calling for the special and differential treatment of developing countries. The WTO's special, and differential treatment has been extended to include measures of technical assistance, and extended transition periods to enable countries to meet their commitments in new areas agreed on in the Uruguay round of negotiations. At the same time, many WTO provisions encourage industrial countries to give developing countries preferential treatment, through a variety of measures, none of them legally enforceable. The author concludes that weaknesses in the institutional capacity of many developing countries, provide a conceptual basis for continuing special, and differential treatment in the WTO, but that the benefits should be targeted only to low-income developing countries, and those that need help becoming integrated with the international trading system. In addition...

At each stage of the product development process, the designers are facing an important task which consists of decision making. Two cases are observed: the problem of concept selection in conceptual design phases and, the problem of pre-dimensioning once concept choices are made. Making decisions in conceptual design phases on a sound basis is one of the most difficult challenges in engineering design, especially when innovative concepts are introduced. On the one hand, designers deal with imprecise data about design alternatives. On the other hand, design objectives and requirements are usually not clear in these phases. The greatest opportunities to reduce product life cycle costs usually occur during the first conceptual design phases. The need for reliable multi-criteria decision aid (MCDA) methods is thus greatest at early conceptual design phases. Various MCDA methods are proposed in the literature. The main criticism of these methods is that they usually yield different results for the same problem. In this work, an analysis of six MCDA methods (weighed sum, weighted product, Kim & Lin, compromise programming, TOPSIS, and ELECTRE I) was conducted. Our analysis was performed via an industrial case of solar collector structure development. The objective is to define the most appropriate MCDA methods in term of three criteria: (i) the consistency of the results...

Every experiment or observational study is made in a context. This context is being explicitly considered in this book. To do so, a conceptual variable is defined as any variable which can be defined by (a group of) researchers in a given setting. Such variables are classified. Sufficiency and ancillarity are defined conditionally on the context. The conditionality principle, the sufficiency principle and the likelihood principle are generalized, and a tentative rule for when one should not condition on an ancillary is motivated by examples. The theory is illustrated by the case where a nuisance parameter is a part of the context, and for this case, model reduction is motivated. Model reduction is discussed in general from the point of view that there exists a mathematical group acting upon the parameter space. It is shown that a natural extension of this discussion also gives a conceptual basis from which essential parts of the formalism of quantum mechanics can be derived. This implies an epistemological basis for quantum theory, a kind of basis that has also been advocated by part of the quantum foundation community in recent years. Born's celebrated formula is shown to follow from a focused version of the likelihood principle together with some reasonable assumptions on rationality connected to experimental evidence. Some statistical consequences of Born's formula are sketched. The questions around Bell's inequality are approached by using the conditionality principle for each observer. The objective aspects of the world are identified with the ideal inference results upon which all observers agree (epistemological objectivity).; Comment: 98 pages; invited as a Springer Brief

We establish a previously conjectured connection between $p$-adics and quantum groups. We find in Sklyanin's two parameter elliptic quantum algebra and its generalizations, the conceptual basis for the Macdonald polynomials, which ``interpolate'' between the zonal spherical functions of related real and $p$\--adic symmetric spaces. The elliptic quantum algebras underlie the $Z_n$\--Baxter models. We show that in the $n \air \infty$ limit, the Jost function for the scattering of {\em first} level excitations in the $Z_n$\--Baxter model coincides with the Harish\--Chandra\--like $c$\--function constructed from the Macdonald polynomials associated to the root system $A_1$. The partition function of the $Z_2$\--Baxter model itself is also expressed in terms of this Macdonald\--Harish\--Chandra\ $c$\--function, albeit in a less simple way. We relate the two parameters $q$ and $t$ of the Macdonald polynomials to the anisotropy and modular parameters of the Baxter model. In particular the $p$\--adic ``regimes'' in the Macdonald polynomials correspond to a discrete sequence of XXZ models. We also discuss the possibility of ``$q$\--deforming'' Euler products.; Comment: 25 pages

Organisms respond to their surroundings at multiple spatial scales, and different organisms respond differently to the same environment. Existing landscape models, such as the "fragmentation model" (or patch-matrix-corridor model) and the "variegation model," can be limited in their ability to explain complex patterns for different species and across multiple scales. An alternative approach is to conceptualize landscapes as overlaid species-specific habitat contour maps. Key characteristics of this approach are that different species may respond differently to the same environmental conditions and at different spatial scales. Although similar approaches are being used in ecological modeling, there is much room for habitat contours as a useful conceptual tool. By providing an alternative view of landscapes, a contour model may stimulate more field investigations stratified on the basis of ecological variables other than human-defined patches and patch boundaries. A conceptual model of habitat contours may also help to communicate ecological complexity to land managers. Finally, by incorporating additional ecological complexity, a conceptual model based on habitat contours may help to bridge the perceived gap between pattern and process in landscape ecology. Habitat contours do not preclude the use of existing landscape models and should be seen as a complementary approach most suited to heterogeneous human-modified landscapes.

This article is based on the assumption that values education has much to offer to a country that is struggling to overcome a fractured moral landscape. Pursuing a modest agenda, the focus of the article is on values and values education in the context of schooling in South Africa. We suggest that debates about what constitutes values and values education raise important philosophical and pedagogical questions about what values are and which values should be prioritized. We contend that it is unlikely that values education will in any significant way meet the expectations of South Africa's Constitution and its national school curriculum intentions, if it is not underpinned by conceptual clarification of what values are in relation to the role that values education is expected to fulfil in South Africa's schools. Intended as a conceptual investigation, the article explores different interpretations, tensions and assumptions that confront the notions of values and values education. We suggest that the insights from such a conceptual clarification could provide an appropriate platform not only for a coherent approach to values education, but also for the more effectual transfer and take up of values in schools. We favour a pragmatist conception based on the notion 'shared goods' in terms of which values education in schools can lay the basis for dialogical encounters necessary for addressing our country's diverse and even divergent values orientations.
