Plot Erosion Model Using Gray Relational Analysis Method

The main factors affecting interrill erosion-including runoff discharge, rainfall intensity, mean flow velocity, and slope gradient-were analyzed by using a gray relational analysis. An equation for interrill erosion was derived by coupling this analysis with dimensional and regression analyses. The values of erosion rates predicted by this equation were in good agreement with experimental observations.

Grey relational analysis on the relation between marine environmental factors and oxidation-reduction potential

The effects of marine environmental factors-temperature (T), dissolved oxygen (DO), salinity (S) and pH-on the oxidation-reduction potential (ORP) of natural seawater were studied in laboratory. The results show an indistinct relationship between these four factors and the ORP, but they did impact the ORP Common mathematical methods were not applicable for describing the relationship. Therefore, a grey relational analysis (GRA) method was developed. The degrees of correlation were calculated according to GRA and the values of T, pH, DO and S were 0.744, 0.710, 0.692 and 0.690, respectively. From these values, the relations of these factors to the ORP could be described and evaluated, and those of T and pH were relatively major. In general, ORP is influenced by the synergic effect of T, DO, pH and S, with no single factor having an outstanding role.

Framework for the relational analysis of texts : theory and practice.

This workshop is useful for academic researchers and postgraduate students who wish to explore relational approaches to the examination of the organisation of academic texts.
The first part of the workshop introduces the theory and premises of the framework for the rhetorical analysis of the structure of texts (FARS). FARS provides a functional account of the structure of text in terms of the strategies employed by writers to achieve their communicative purposes. Its coherence relations obtain from the level of text as a whole to the clausal level. The discourse parts at all levels except the bottom level constitute relational schemata. FARS relational taxonomy includes the following relational clusters: Elaboration, List, Causal, Adversative, Facilitation, Assessing and Digression. The second part of the workshopl provides opportunity to practice relational analyses of selected texts within this framework.

National Minorities, Nationalizing States, and External National Homelands in the New Europe. Notes toward a Relational Analysis. Institute of Advanced Studies Political Science Series, 11 December 1993

Nationalism remains central to politics in and among the new nation-states. Far from »solving« the region's national question, the most recent reconfiguration of political space – the replacement of the Soviet Union, Yugoslavia, and Czechoslovakia by some twenty would-be nation-states – only recast it in a new form. It is this new phase and form of the national question that I explore in this paper. I begin by outlining a particular relational configuration – the triadic relational nexus between national minorities, nationalizing states, and external national homelands – that is central to the national question in post-Soviet Eurasia. In the second, and most substantial, section of the paper, I argue that each of the »elements« in this relational nexus – minority, nationalizing state, and homeland – should itself be understood in dynamic and relational terms, not as a fixed, given, or analytically irreducible entity but as a field of differentiated positions and an arena of struggles among competing »stances.« In a brief concluding section, I return to the relational nexus as a whole, underscoring the dynamically interactive quality of the triadic interplay.

Grey interrelation analysis to assess the influence of elements on the galvanic efficiency of Al sacrificial anode

Grey interrelation analysis method was used to study the correlation of Al-anode elements and its galvanic efficiency at 20 degreesC, 40 degreesC and 60 degreesC. Twenty-eight kinds of Al-anodes were made for experiments by the method given by Chinese National Standard GB4948-85 [1] and the correlation degree of elements added in the anodes were calculated. The results showed that the order of elements affecting galvanic efficiency at different temperature is basically the same, and the correlation degree can reflect the variation of Al-anode galvanic efficiency when changing temperature. It is suggested that the elements being added in Al-anode are Zn, In, Ga, Mg.

The distribution of discoursal salience in research papers: relational hypotaxis and parataxis

In this article I challenge the claim that nuclearity is a central principle in the organization of texts. I propose the Framework for the Relational Analysis of Texts (FARS) which accounts for the paratactic and hypotactic realization of coherence relations. Within this framework, the taxis of coherence relations is co-textually dictated. I consider the writer choices in the distribution of discoursal salience and the intertextual and intercultural variation of these choices. It is suggested that divergence between approaches that perceive text as exhibiting both hypotactic and paratactic organization and those that see nuclearity as a basic characteristic of text structure arises from differences in the linguistic corpora examined during the construction of respective theoretical frameworks.

Memes pluralistas práticas linguístico-midiáticas em fenômenos bilíngues: um estudo sistêmico-funcional e multimodal sobre propagação via corpora digitais

Investigou-se pelo presente estudo se a concepção presente na Teoria de Replicadores, expressa através do conceito de meme (DAWKINS, 1979), poderia ser um modelo compatível para explicar a propagação de memes no substrato das mídias sociais. No âmbito dos estudos locais, Recuero (2006) sugeriu uma transdução desse modelo, baseando-se nas concepções de Dawkins (1979). Refletindo sobre o posicionamento epistemológico de Recuero (2006), o presente trabalho, baseando-se em Dennett (1995), Blackmore (2002) e Tyler (2011b; 2013b), procedeu às instâncias de Análise Conceitual e Composicional dessa transdução. A partir do conceito de memeplexo (BLACKMORE, 2002), esta pesquisa de base linguística (HALLIDAY, 1987) entende os memes, no substrato das mídias digitais/sociais, como práticas de produção e distribuição linguístico-midiáticas, propaladas a partir de diversas unidades de propagação e das relações criadas pelos internautas nesse processo de transmissão. Investigando tais relações, a partir da instância de Análise Relacional, propõe-se examinar duas unidades de propagação. Expressões meméticas (Que deselegante e #Tenso) e imagens meméticas (oriundas do fenômeno memético Nana em desastres). Integram este estudo dois corpora de expressões meméticas (5275 postagens oriundas ou redirecionadas para o Twitter.com total de 83.655 palavras/tokens) e um corpus bilíngue (Português/Inglês) de imagens meméticas (um total de 134 imagens oriundas do Tumblr.com e Facebook.com). Para analisar os corpora de expressões meméticas utilizou-se a metodologia de Linguística de Corpus (BERBER-SARDINHA, 2004; SHEPHERD, 2009; SOUZA JÚNIOR, 2012, 2013b, 2013c). Para a análise do corpus multimodal de imagens meméticas, utilizou-se a metodologia que chamamos de Análise Propagatória. Objetivamos verificar se essas unidades de propagação e as práticas linguístico-midiáticas que estas transmitem, evoluiriam somente devido a aspectos memético-midiáticos, conforme Recuero (2006) apontara, e com padrão de propagação internalista (DAWKINS, 1979; 1982). Após análise dos dados, revelou-se que, ao nível do propósito, os fenômenos locais investigados não evoluíram por padrão internalista (ou homogêneo) de propagação. Tais padrões revelam ser de natureza externalista (ou heterogênea). Ademais, constatou-se que princípios constitutivos meméticos de evolução como os de fecundidade, longevidade (DAWKINS 1979; 1982) e o de design (DENNETT, 1995), junto com o princípio midiático de evolução de alcance (RECUERO, 2006) mantiveram-se presentes com alto grau de influencia nas propagações de natureza externalista. Por outro lado, o princípio memético da fidelidade (DAWKINS, 1979; 1982) foi o que menos influenciou esses padrões de propagação. Neutralizando a fidelidade, e impulsionados pelo princípio de design, destacaram-se nesse processo evolutivo os princípios linguísticos sistematizadores revelados por este estudo. Isto é: o princípio da funcionalidade (memes evoluem porque podem indicar propósitos diferentes) e o princípio do alcance linguístico (memes podem ser direcionados a itens animados/ inanimados; para internautas em idioma nativo/ estrangeiro)

What is poverty? A diachronic exploration of the discourse on poverty from the 1970s to the 2000s

Poverty is central to the concept of development. However, the relevance given to particular aspects of poverty has changed over the years and with it the manner in which poverty has been represented. The following paper explores how concepts of poverty within the 'poverty discourse' have altered over a 30-year period. A diachronic analysis is performed to explore changes in the topical and thematic composition of the definitions, in addition to the manner in which poverty has been 'framed'. The results illustrated that poverty was variably framed across the decades ranging from a 'neutral' fact to a highly contested state with little agreement over causes and consequences. Nevertheless, the relational analysis revealed the de-problematization of poverty over time. The finding has clear implications for development praxis: poverty needs to be 'attacked', but the root causes, at least from a discursive perspective, may be ignored.

An assessment of criteria to evaluate the graduate education program in Brazil

This study sought to identify criteria adequate for the evaluation of graduate programs in Brazil. A survey was the means for collecting the ratings and rankings given by faculty members at selected Brazilian graduate programs. A questionnaire using Likerttype and ranking items asked the importance attributed by each respondent to each of the 109 items listed. The data analysis reported in this dissertation indicates that the most highly rated criteria and indicators were: (1) Library: current periodicals; (2) Facilities: classrooms and laboratories; (3) Library: books and monographs; (4) Academic Environment: discussion, investigation, and expression; and (5) Facilities: research space and equipment. The study presents the means and standard deviations obtained for each indicator and also includes some figures obtained for a relational analysis. This dissertation was developed to provide useful information to educational planners, policy makers, administrators, and evaluators involved in Brazilian higher education or comparative studies. It is suggested that additional investigations concentrate on more specific and in-depth analysis and interpretation of the policymaking processes, i.e., on the study of social facts or organizational and academic variables in their relationships with aspects of the educational system. The appendices section includes a facsimile of the questionnaire and additional data.

Fatores que influenciam a fidelidade dos clientes em postos de combustíveis da cidade de Natal/RN

The customer loyalty became strategy factor for the sustainability of business enterprises. And will be them competitive is important to describe the factors than the consumers consider for to choose the business than will buy the product or service. The dissertation objective is to know the factors that influence the consumer s satisfaction and loyalty in gas stations of Natal/RN, using the index national of customer satisfaction. The literature review was directed for strategy concepts, service quality, satisfaction and fidelity consumer and index national of customer satisfaction. The method used was descriptive-explicative, with application of a survey, from march 15 until april 15 of 2013, with 391 consumers of gas station. In relational analysis, we considered eight constructs: quality, price, complaints, satisfaction, image, loyalty, affection and commitment calculated. For customer satisfaction, the factors that influence have resulted in fuel quality, technical skills of vendors and duration of service. For customer loyalty, the factors that influence resulted in: image, feeling for distributor flag post, location and overall satisfaction with the gas station

Hombre y filosofía

La presente tesis pretende mostrar cómo lo místico se vertebra en la filosofía siendo lo antropológico lo que opera dicha vertebración tomando como referente la tensión hacia lo absoluto que hay en cada ser humano. La propuesta se diseña en dos grandes bloques: el primero despeja la raigambre del elemento místico en contrapunto con la historia de la racionalidad, repartido en cuatro capítulos que analizan la fenomenología del hecho místico desde la noticia histórico-discursiva y su necesaria hermenéutica, desarrollo que conduce a dos instancias cruciales: el aparente dilema racionalidad-misticismo y la consecuente validación epistemológica del análisis relacional situado en el umbral mística-filosofía. El segundo bloque consta de cinco capítulos que parten de una breve relevamiento del manantial místico que operó de fuente en que abrevaron los cuatro filósofos seleccionados – Unamuno, Bergson, Stein y Mounier – para poder así desarrollar adecuadamente sus propuestas insistiendo en el ángulo cognitivo que nos aboca. Ambos bloques convergen finalmente en las consideraciones últimas que recogen en cuatro ejes temáticos las instancias decisivas a que nos ha conducido el proceso integral de nuestra indagatoria, proceso donde se hace patente la intrínseca co-referencialidad entre el fenómeno ‘mística’ y el fenómeno ‘hombre’ vertidos en la discursividad filosófica.

Una leve Arqueología de la escala

Esta es una tesis con dos partes bien diferenciadas; en la primera se habla de conceptos como la escala, el tamaño y la medida en el mundo de la antigua Roma. Para ello se eligen edificios con características específicas que pueden explicar estos términos, como la” Villa Adriana” en la que se habla del tamaño desde la acumulación de dimensiones medias, el “Ara Pacis”, en la que se describe la ambigüedad dimensional y el tamaño, el Panteón en el que habla de la escala, y el Santuario de Baalbek a través del cual se reflexiona sobre la condición de monumentalidad. Dichos edificios se comparan con piezas de arte contemporáneo que ayudan a entender el contenido histórico. En ese sentido la tesis propone un viaje desde lo moderno a lo antiguo, instalándose en la certeza de que el conocimiento ampliado de los conceptos contemporáneos otorga nueva vida a los edificios históricos, en un paseo inverso al clásico de estudiar lo antiguo para entender el presente. La tesis defiende que el presente se lee desde el presente y el pasado también desde el presente, elaborando nuevas narrativas que permiten superponer realidades distintas para alumbrar lo real. La segunda parte de la tesis compara la medida de lo público y lo privado así como la medida del paisaje. Habla de la medida del Poder ejemplificada en el proyecto de los Foros Imperiales desde el Foro de César hasta el Foro de Trajano y elabora una comparación dimensional desde la disección de sesenta casas pompeyanas, que son sometidas a un cuidadoso análisis métrico y relacional. Se estudian así mismo sus distintas proporciones desde el tratado de Vitrubio y se analizan sus sistemas de proyecto, encontrando en la ampliación acumulativa un mecanismo que relaciona lo público y lo privado. Por último se estudia la medida del paisaje, encontrando un apoyo en la pintura mural romana y también en la relación entre los cuatro Santuarios Republicanos de Lacio. ABSTRACT This is a thesis with two different parts; the first one deals with concepts from the Ancient Rome, such as scale, size and measure. Some buildings with specific characteristics have been chosen in order to explain these terms, such as "Villa Adriana" where size is formed by the accumulation of medium sizes, the "Ara Pacis",where the dimensional ambiguity is described, the Pantheon where the scale is explained and the Sanctuary of Baalbek where the condition of monumentality is understood. These buildings are compared with contemporary artworks that help to understand the historical contents. In that sense, the thesis proposes a journey from the modern to the old, settling in the certainty that the extended knowledge of contemporary concepts gives new life to historic buildings, instead of the usual walk to the old to understand the present . The thesis argues that both the present and the past can be read through the present, developing new narratives that are overlayed to light reality. The second part of the thesis compares the measures in public and private worlds as well as the measure in the landscape. It is also about the measure of the power, that is exemplified in the Fori Imperiali as the Forum of Caesar and Trajan's Forum. Besides a dimensional comparison is made by dissecting sixty Pompeian houses, which are subjected to careful and relational analysis. Furthermore, their different proportions are studied, since the Treaty of Vitruvius and their design systems are analyzed, finding the mechanism that links the public and private spheres in the cumulative expansion. Finally , the measure of the landscape is studied supported by Roman wall painting and in the relationship between the four Sanctuaries Republicans of Lazio.

Ergociudad: concepción modélica de la calidad de vida urbana desde la perspectiva de la ergonomía y el diseño urbano

Este documento corresponde a la Tesis para optar al grado de Doctor en Arquitectura y Urbanismo en el marco del Programa de Doctorado conjunto de la Universidad Politécnica de Madrid y la Universidad de Chile. La investigación realizada es de carácter exploratorio-descriptivo con el propósito de establecer y relacionar conceptualmente las teorías y principios de la ergonomía y del diseño urbano, para proponer desde un enfoque sistémico criterios de confort en el diseño de la ciudad, que contribuyan a la calidad de vida y la vida urbana, dando a luz lineamientos para la “Ergociudad”; concepto que surge de la unión de las palabras Ergonomía y Ciudad. Al estudiar a diversos autores se concluye en la carencia de referentes de confort y de políticas basados en la relación empírica del ser humano en la ciudad que posibiliten la configuración del medio ambiente urbano a partir de ella. La ciudad se piensa y se construye desde su estructura y no desde una mirada sistémica e integrada de los factores dimensionales, ambientales y psicosociales condicionantes del confort en sus distintas escalas. La mirada respecto del desarrollo de la ciudad es físico constructiva y, por tanto, deja de lado el problema de los estresores o de la percepción de los factores de riesgo en el entorno construido. El tema central de esta tesis es proponer una estructura modélica de calidad de vida urbana denominada Ergociudad en base a los fundamentos teóricos de la Ergonomía y el Diseño Urbano y establecer el “Índice Ergourbano”, como representación de los factores ergonómicos presentes en la ciudad. En este marco, el enfoque de la ergonomía y sus prestaciones han sido trabajados en orden a facilitar mecanismos para disponer de sus procedimientos y de su modelo de análisis relacional a otras escalas. El concepto de “Ergociudad” y su propuesta de exploración desde las personas, postula una mirada sobre los problemas que enfrenta el ser humano en la ciudad considerando la dimensión de lo humano, desde perspectivas psicológicas y sociológicas para establecer y configurar la percepción de estrés y bienestar; la dimensión de lo urbano, representada por los objetos que componen el entorno (en sus distintas escalas); y, la dimensión de lo perceptual, que definiría el concepto de confort en la forma de comprender el mundo sensorial. Los resultados de la investigación confirman la hipótesis de trabajo en términos de demostrar que la percepción de disconfort en la ciudad reflejado en un índice de evaluación perceptual espacial denominado índice Ergourbano obtenido de las mediciones en situ de los factores ergonómicos del entorno. Los resultados finales de la tesis han permitido identificar variables afines en los aspectos espaciales y perceptuales. Ello mediante la exploración de las situaciones urbanas y sus conexiones para establecer el grado de adecuación del espacio urbano a las prácticas, usos y modos de las personas en la ciudad. Una vez aplicado y validado el método desarrollado se ha llegado a obtener información suficiente para aumentar el nivel de conocimiento sobre el espacio urbano con un enfoque relacional que permite entenderlo desde la experiencia de las personas que lo habitan, insistiendo en su aporte metodológico y proyectual considerando la inexistente aplicación de información que vincule la ergonomía a esta escala urbana. ABSTRACT This document corresponds to the thesis to obtain the degree of Doctor of Architecture and Urbanism in the framework of the combined doctorate program of the Technical University of Madrid and the University of Chile. The research carried out is of a descriptive–explanatory nature with the objective of establishing and conceptually relating the theories and principals of ergonomics (or human factors) and urban design. This is done in order to propose, from a systematic focus, comfort criteria in the design of cities that contribute to quality of life and urban life, giving birth to chacteristics for “Ergocity”; concepts that arise from the union of the words ergonomic and city. After studying diverse authors, one concludes the lack of references toward comfort and policies based on the empirical relation of humans in the city that allow for the configuration of the urban environment based on comfort. The city is thought out and built from its structure and not from a systematic and integrated viewpoint of the dimensional, environmental and psychosocial factors, determining factors of comfort in its distinct scales. The view regarding the development of the city is physical constructive and, therefore, leaves aside the problem of the stress factors or the perception of risk factors in the constructed environment. The central theme of this thesis is to propose a quality model of urban life entitled Ergo-city, based on the fundamental theories of the ergonomics and urban design, and to establish an “Ergourban index” as representation of the ergonomic factors present in the city. In this framework, the focus of ergonomics and its services have been used in order to facilitate mechanisms to arrange their procedures and their model of relational analysis on other scales. The concept of “Ergocity”and its offer of exploration from a people perspective, proposes a look at the problems that humans face in the city considering the nonhuman dimension, from psychological and sociological perspectives to establish and configure la perception of stress and well-being: the urban dimension, represented by the objects that the surroundings are made up of (on their distinct scales), and the perceptual dimension, which will define the concept of comfort by means of understanding the sensorial world. The results of the research confirm the working hypothesis in terms of demonstrating the perception of discomfort in the city reflected in an index of perceptual/spatial evaluation named ergo-urban obtained from in situ measurements of the ergonomic factors of the surroundings. The final results of the thesis have permitted the identification the identification of variables related to the spatial and perceptual aspects. All of this through the exploration of the urban situations and their connections in order to establish the level of adaptation of the urban space to the practices, uses and modes of the people in the city. Once applied and validated, the method of development has led to the collection of sufficient information to increase the level of knowledge of the urban space with a relational focus that allows us to understand it from the experience of the people who inhabit said space, persisting with its methodological and projective contribution considering the inexistent application of information that links the ergonomics on an urban scale.
