Ontologia aplicada no mapeamento de classe de dados para a melhoria do intercambio de dados na cotonicultura no Brasil. / Ontology applied in mapping the data class for improved data sharing on cotton production in Brazil.

Clóvis dos Santos Júnior 10 April 2014 (has links)
A gestão da cotonicultura depende de dados com qualidade para a criação de informações que possam auxiliar a tomada de decisões nos processos agrícolas. Parte dessa tarefa depende da legibilidade dos dados gerados, necessários para os processos desse segmento. Com isso, o mapeamento das classes de dados mais relevantes é fundamental para a homogeneização de dados e posterior criação de soluções computacionais. Apesar da clareza da necessidade de recursos de tecnologia da informação para melhorar a gestão na agricultura, há poucos padrões desenvolvidos ou em desenvolvimento para esse fim. Os padrões existentes são específicos ou proprietários, dificultando tanto a homogeneização quanto o compartilhamento de dados. Assim, a proposta da pesquisa foi mapear os processos da produção de fibra de algodão no Brasil, por meio de uma ontologia de domínio, resultando em conhecimento para a criação de um padrão de metadados contribuindo com a melhoria no processo de intercâmbio de dados nesse segmento e também para a melhoria da qualidade de dados na cotonicultura por meio da melhoria nas dimensões de: integridade de dados, completeza e acessibilidade. A validação do padrão de metadados resultante foi realizada por meio de uma prova de conceito verificando as contribuições tanto para o desenvolvimento de software quanto para melhoria da integridade e qualidade de dados na cotonicultura. / The management of cotton production depends on quality data to create helpful information to decision-making in agricultural processes. Some tasks depend on the readability of the data generated and necessary to process this segment. Thus, the mapping of classes most relevant data is crucial for homogenizing data and then creating computational solutions. Despite the clear need for IT resources to improve management in agriculture, there are few standards developed or under development for this purpose. Existing standards are specific or legacy, hindering both homogeneity and data sharing. Thus, the research proposal is to map the cotton fiber production processes in Brazil, using the domain ontology, resulting in knowledge to create a metadata standard contributing to the improvement in the data exchange process in this segment and also improving data quality in cotton production, improving data integrity in dimensions such as completeness and accessibility. The validation of the resulting metadata standard was performed using proof of concept to verify the contributions both for software development and for improving the quality and integrity of data in the cotton industry.

Realismo e racionalidade: o otimismo epistêmico em questão / Realism and rationality: the epistemic optimism in question

Assis, Emerson Ferreira de 07 February 2014 (has links)
O realismo científico é uma concepção filosófica da ciência que assume uma atitude epistêmica positiva em relação às melhores teorias científicas disponíveis, recomendando, sob algumas circunstâncias (em geral o atendimento de princípios metodológicos bem estabelecidos), a crença nas afirmações que estas teorias fazem a respeito do observável e do inobservável. Hilary Putnam, um dos nomes mais salientes no atual cenário filosófico anglofônico, é um autor que, mesmo tendo mudado diversas vezes concepções centrais de suas propostas filosóficas, tem no realismo científico um interesse perene. Em sua mais recente produção, tem defendido que a relatividade conceitual (uma marca característica de muitas abordagens antirrealistas acerca da ciência) é compatível com o realismo científico (Putnam: 2012; p. 63). Esse trabalho procurará investigar a possibilidade de sustentar a proposta de Putnam, analisando a relatividade conceitual e os pressupostos realistas no campo que efetivamente separa as posições realistas e antirrealistas da ciência: o entendimento do que as melhores teorias científicas afirmam sobre o inobservável. Antirrealistas são em geral agnósticos em relação às proposições sobre o inobservável, ou instrumentalistas em relação a essa parte da teorização científica, ao passo que realistas (sob as circunstancias acima evocadas) afirmam que é epistemicamente justificável acreditar na existência dos ditos inobserváveis e que a descrição científica dos mesmos representa características desses eventos ou objetos. Concluímos que a proposta de Putnam leva ao que o mesmo chama em Ética Sem Ontologia a uma Objetividade sem Objetos, uma forma de realismo local (aqui entendido como envolvimento direto com o processo de mensuração/interação do objeto ou evento), de caráter eminentemente estrutural e cujo pronunciamento ontológico mais significativo é de que o mundo responde e restringe nossas ações, e esse responder (uma metáfora adequada seria ressoar) nos permite conhecê-lo. Construímos imagens do mundo, mas uma ontologia final assim como uma narrativa absoluta dos eventos está fora de nossas possibilidades cognitivas. / Scientific realism is a philosophical conception of science that assumes a positive epistemic attitude about the best available scientific theories, recommending, under some circumstances (usually the meeting of some well established methodological principles), the belief concerning what these theories claim about the observable and unobservable. Hilary Putnam, one of the most prominent names in the current Anglophonic philosophical scene, is an author even having changed central conceptions in their philosophical thought along time, keep scientific realism as an perennial interest. In his latest production, has argued that conceptual relativity (one hallmark of many anti-realists approaches about science) is compatible with scientific realism (Putnam 2012, p. 63). This work will seek to investigate the possibility of supporting what was proposed by Putnam, analyzing conceptual relativity and realistic assumptions in the field that effectively separates realistic and anti-realists conceptions of science: understanding what the best scientific theories say about unobservable. Anti-realists are at large agnostic about the unobservable or instrumentalists in relation to that part of scientific theorizing, while scientific realists ( under the circumstances mentioned above ) say the believe in the existence of said \"unobservable\" is epistemically justified, as the scientific description of that events or objects. We conclude the Putnam idea leads to what they call in \"Ethics Without Ontology\" for a \"Objectivity without objects\", a form of local realism (here understood as direct involvement with the measurement process / interaction with the object or event), eminently structural character and whose ontological statement more significant is the world responds and restricts our actions, and that answer (an apt metaphor would be resonate) allows us to meet him. We build images of the world, but an final ontology as well as an absolute narrative of events are out of our cognitive possibilities.

Deep Impression

Jönsson, Jennifer Annie Patricia January 2019 (has links)
The scope of this thesis is to reveal the hidden dimensions of fashion. With the aim to stress the worth of participation and the individual experience of fashion. This work is questioning what we see, and later what is actually there. Through a thorough investigation of the knit technique the relationship of loop and thread (pause and activity) is the focus of this paper. Enhancing the significant qualities of the knitted technique, where material and shape is born simultaneously, the result presented holds a variety of results. With the aim to discuss multiple dimensions this knit investigation is presented in a fashion context. Styled with technical sportswear this work is challenging knitwear -as well as sportswear. By clashing sports connotated materials with the knitted wool, both fields are expanded and new options and expression are presented. The motive of this investigation is to further state the worth of fashion. To create a space for the experience of fashion, stating the various result that is not depending on the presentation on body. This work questions the pre-set truths and conventions of what fashion could be, and our ability to judge what is presented for us.

A Study of Cell Dimensions, Amyloplast Position and Certain Physiological Responses During Gravitropic Bending of Dicot Stems

Sliwinski, Julianne E. 01 May 1982 (has links)
If a plant is positioned horizontally, the elongating region responds by bending upward within 10 to 12 h until it is vertical, forming a goo bend with the stem below. If a Xan thiv~ strumarium L. (cocklebur) plant is placed horizontally, but restricted to that position for 48 h and then released, the bend to the vertical usually takes place within 10 s, suggesting that bending energy is stored in restricted stems . Some plants that do not bend completely to 90 within 10 s do so within 5 min, and other plants can overshoot the 90 mark by as much as sao. Microscopic measurements show that cells on the bottom of stems that have been restricted and then released are longer and narrower than cells on the bottom of restricted stems; cells on the top of restricted-and-released stems are shorter and thicker than those on the top of restricted stems . Thus, stems bend upward rapidly after release in response to changes in cell dimensions, but apparently with conservation of cell volume (i.e., little or no movement of water in or out of cells during the rapid bending ). The increased diameter of the cells on the bottom of restricted plants indicates that the cells are taking up water before they are released {apparently accompanied by an increase in cell wall area), while they are not allowed to increase much in length. Any increase in length was accompanied by stretching of cells on top. Thus, energy for bending was stored in stretched upper cells and compressed lower cells that have taken up water. It was al so shown that graviperception takes place in the very tissue that bends, and this perception is not a perception of the tension and compression caused by the weight of a horizontal stem. Also, amyloplasts were found in a sheath also in the region of bending and were found to settle in the direction of gravity. The location of the sheath between the vascular tissue and the cortex lead to a proposed model of graviperception for green vegetative dicot shoots.

The primary school as an emotional arena : a case study in collegial relationships

Jarzabkowski, Lucy M., n/a January 2001 (has links)
The thesis is an exploratory and descriptive study focusing on the emotional dimensions of collegial relationships in a primary school. The research is timely given the current pressures to develop cultures of collaboration and shared leadership in schools today. The study concentrates on the non-classroom work of teachers and investigates three particular areas of school life: the collegial practices of staff; the emotional milieu of teachers' work; and the contributions of members towards an emotionally healthy staff community. An interpretive tradition has been used in conducting the research, thus giving voice to the perceptions of research participants about their work. The research was conducted as an ethnographic case study. Data were gathered largely through participant observation and interviews. The researcher visited the school on a regular basis through the course of one school year, averaging over one day per week working in the school. Eighteen staff members were formally interviewed, the principal and assistant principal on several occasions. Extensive fieldnotes and interview transcripts were created and, aided by NVivo, a computer package for the analysis of non-statistical data, data were broken down into categories and resynthesised to bring to life a picture of the lived reality of collegiality for staff members in a primary school. The study adds to new knowledge in several important ways. First, it allows for a reconceptualisation of teachers' work. It shows how many different practices contribute to a collegial culture within a primary school and demonstrates how the social and emotional dimensions of collegiality are significant in the development of professional relationships. Second, the study develops an understanding of emotional labour for school personnel and contributes importantly to a broader picture of how emotional labour can be practiced, particularly for the sake of collegiality. It is posited that different kinds of emotional labour exist within the school setting, and that emotional labour in schools may be different from that in some other service organisations. The study explores bounded emotionality as a cultural practice among staff, suggesting that it allows expression of emotions about classroom work while at the same time constrains negative emotional displays so as to build and maintain community. The study suggests that the principles of bounded emotionality, as they operate within the primary school, present both benefits and burdens for a collegial staff, but may encourage an emotionally healthy workplace.

Compensation between warmth and competence : antecedents and consequences of a negative relation between the two fundamental dimensions of social perception

Kervyn, Nicolas 27 November 2008 (has links)
Our research focuses on the negative relationship between the two fundamental dimensions of social perception, warmth and competence. Specifically, we examine antecedents and consequences of what has been called the compensation effect, i.e., perceivers’ tendency to differentiate two social targets in a comparative context on the two fundamental dimensions by contrasting them in a compensatory direction. In order to present our theoretical background and highlight the relevance of our empirical research, the first chapter of this theoretical part reviews the research that has identified competence and warmth as the two fundamental dimensions of social perception, and the second chapter reviews how these two dimensions have been used in social psychology. In the third chapter, we review the work that has concentrated on the properties of these two dimensions. And in the fourth and final theoretical chapter, we present recent research that has tested the compensation effect empirically and that constitutes the starting point of the present endeavor. In the experimental part, our ambition has been to get a better understanding of the compensation effect. In Chapter 5, we identify a necessary condition of the emergence of a compensation effect, namely that it is observed on the two fundamental dimensions of social perception, not on any given pair of dimensions. In three experiments we first replicate the compensation effect on the two fundamental dimensions, then we show that if the unmanipulated dimension is not one of the two fundamental dimensions, then a halo effect is observed when a compensation effect would have been observed with the fundamental dimensions. In Chapter 6, we show how the compensation effect affects social perception beyond impression formation. We do so by showing a compensation effect on indirect measures. In the Chapter 7 we test two original predictions based on the compensation effect. First we predict and find that context can affect the ratings of a specific group in a compensatory way. And we show that the compensation effect can be found on mean ratings, and at the correlational level. Second we predict and show that the compensation effect will lead to more differenciated judgments of groups that have a compensatory profile than those that have a halo profile. This is a doctoral thesis based on a series of articles. Therefore we ask the reader to understand that there will be redundancies in the five theoretical introductions of the articles and a number of cross references.
