Повний текст джерелаThe principal aim of this research is describing to which extent formal models for linguistic data structuring are crucial in Natural Language Processing (NLP) applications. In this sense, we will pay particular attention to those Knowledge Management Systems (KMS) which are designed for the Internet, and also to the enhanced solutions they may require. In order to appropriately deal with this topics, we will describe how to achieve computational linguistics applications helpful to humans in establishing and maintaining an advantageous relationship with technologies, especially with those technologies which are based on or produce man-machine interactions in natural language. We will explore the positive relationship which may exist between well-structured Linguistic Resources (LR) and KMS, in order to state that if the information architecture of a KMS is based on the formalization of linguistic data, then the system works better and is more consistent. As for the topics we want to deal with, frist of all it is indispensable to state that in order to structure efficient and effective Information Retrieval (IR) tools, understanding and formalizing natural language combinatory mechanisms seems to be the first operation to achieve, also because any piece of information produced by humans on the Internet is necessarily a linguistic act. Therefore, in this research work we will also discuss the NLP structuring of a linguistic formalization Hybrid Model, which we hope will prove to be a useful tool to support, improve and refine KMSs. More specifically, in section 1 we will describe how to structure language resources implementable inside KMSs, to what extent they can improve the performance of these systems and how the problem of linguistic data structuring is dealt with by natural language formalization methods. In section 2 we will proceed with a brief review of computational linguistics, paying particular attention to specific software packages such Intex, Unitex, NooJ, and Cataloga, which are developed according to Lexicon-Grammar (LG) method, a linguistic theory established during the 60’s by Maurice Gross. In section 3 we will describe some specific works useful to monitor the state of the art in Linguistic Data Structuring Models, Enhanced Solutions for KMSs, and NLP Applications for KMSs. In section 4 we will cope with problems related to natural language formalization methods, describing mainly Transformational-Generative Grammar (TGG) and LG, plus other methods based on statistical approaches and ontologies. In section 5 we will propose a Hybrid Model usable in NLP applications in order to create effective enhanced solutions for KMSs. Specific features and elements of our hybrid model will be shown through some results on experimental research work. The case study we will present is a very complex NLP problem yet little explored in recent years, i.e. Multi Word Units (MWUs) treatment. In section 6 we will close our research evaluating its results and presenting possible future work perspectives. [edited by author]

Повний текст джерелаIm Sinne der Ideen von Donald E. Knuth ist die Prozessmodellierung sowohl Wissenschaft als auch Kunst. Prozessmodellierung hat immer auch eine ästhetische Dimension. Wie das Komponieren einer Oper oder das Schreiben eines Romans, so stellt auch die Prozessmodellierung einen kreativen Akt eines Individuums dar. Somit kann ein Prozess auf unterschiedlichste Weise modelliert werden. Prozessmodelle können anschließend mit wissenschaftlichen Methoden untersucht werden. Prozessmodelle liegen im Regelfall als gerichtete Graphen vor. Knoten stellen Aktivitäten und Entscheidungspunkte dar, während gerichtete Kanten die temporalen Abhängigkeiten zwischen den Knoten beschreiben. Gängige Prozessmodellierungssprachen, zum Beispiel die Business Process Model and Notation (BPMN) und Ereignisgesteuerte Prozessketten (EPK), ermöglichen die Erstellung von Modellen mit einer beliebig komplexen Topologie. Es gibt keine strukturellen Einschränkungen, welche die Kreativität oder Produktivität durch eine begrenzte Anzahl von Modellierungsalternativen einschränken würden. Nichtsdestotrotz ist es oft wünschenswert, dass Modelle bestimmte strukturelle Eigenschaften haben. Ein bekanntes strukturelles Merkmal für Prozessmodelle ist Wohlstrukturiertheit. Ein Prozessmodell ist wohlstrukturiert genau dann, wenn jeder Knoten mit mehreren ausgehenden Kanten (ein Split) einen entsprechenden Knoten mit mehreren eingehenden Kanten (einen Join) hat, und umgekehrt, so dass die Knoten welche zwischen dem Split und dem Join liegen eine single-entry-single-exit (SESE) Region bilden. Ist dies nicht der Fall, so ist das Modell unstrukturiert. Wohlstrukturiertheit ist aufgrund einer Vielzahl von Gründen wünschenswert: (i) Wohlstrukturierte Modelle sind einfacher auszurichten, wenn sie visualisiert werden, da sie planaren Graphen entsprechen. (ii) Wohlstrukturierte Modelle zeichnen sich durch eine höhere Verständlichkeit aus. (iii) Wohlstrukturierte Modelle haben oft weniger Fehler als unstrukturierte Modelle. Auch ist die Wahrscheinlichkeit fehlerhafter Änderungen größer, wenn Modelle unstrukturiert sind. (iv) Wohlstrukturierte Modelle eignen sich besser für die formale Analyse, da viele Techniken nur für wohlstrukturierte Modelle anwendbar sind. (v) Wohlstrukturierte Modelle sind eher für die effiziente Ausführung und Optimierung geeignet, z.B. wenn unabhängige Regionen eines Prozesses für die parallele Ausführung identifiziert werden. Folglich gibt es eine Reihe von Prozessmodellierungssprachen, z.B. die Business Process Execution Language (BPEL) und ADEPT, welche den Modellierer anhalten nur wohlstrukturierte Modelle zu erstellen. Solch wohlstrukturiertes Modellieren impliziert jedoch gewisse Einschränkungen: (i) Es gibt Prozesse, welche nicht mittels wohlstrukturierten Prozessmodellen dargestellt werden können. (ii) Es gibt Prozesse, für welche die wohlstrukturierte Modellierung mit einer erheblichen Vervielfältigung von Modellierungs-konstrukten einhergeht. Aus diesem Grund vertritt diese Arbeit den Standpunkt, dass ohne strukturelle Einschränkungen modelliert werden sollte, anstatt Wohlstrukturiertheit von Beginn an zu verlangen. Anschließend können, sofern gewünscht und wo immer es möglich ist, automatische Methoden Modellierungsalternativen vorschlagen, welche "besser" strukturiert sind, im Idealfall sogar wohlstrukturiert. Die vorliegende Arbeit widmet sich dem Problem der automatischen Transformation von Prozessmodellen in verhaltensäquivalente wohlstrukturierte Prozessmodelle. Die vorgestellten Transformationen erhalten ein strenges Verhaltensequivalenzkriterium, welches die Parallelität wahrt. Die Resultate sind in einem frei verfügbaren Forschungsprototyp implementiert worden.

Повний текст джерелаSome authors have shown the need of understanding the technological structuring process in contemporary firms. From this perspective, the software industry is a very important element because it provides products and services directly to many organizations from many fields. In this case, the Brazilian software industry has some peculiarities that distinguish it from other industries located in developed countries, which makes its understanding even more relevant. There is evidence that local firms take different strategies and structural configurations to enter into a market naturally dominated by large multinational firms. Therefore, this study aims to understand not only the structural configurations assumed by domestic firms but also the dynamic and the process that lead to these different configurations. To do so, this PhD dissertation investigates the institutional environment, its entities and the isomorphic movements, by employing an exploratory, descriptive and explanatory multiple cases study. Eight software development companies from the Recife's information technology Cluster were visited. Also, a form was applied and an interview with one of the main firm s professional was conducted. Although the study is predominantly qualitative, part of the data was analyzed through charts and graphs, providing a companies and environment overview that was very useful to analysis done through the interviews interpretation. As a result, it was realized that companies are structured around hybrids business models from two ideal types of software development companies, which are: software factory and technology-based company. Regarding the development process, it was found that there is a balanced distribution between the traditional and agile development paradigm. Among the traditional methodologies, the Rational Unified Process (RUP) is predominant. The Scrum is the most used methodology among the organizations based on the Agile Manifesto's principles. Regarding the structuring process, each institutional entity acts in such way that generates different isomorphic pressure. Emphasis was given to entities such as customers, research agencies, clusters, market-leading businesses, public universities, incubators, software industry organizations, technology vendors, development tool suppliers and manager s school and background because they relate themselves in a close way with the software firms. About this relationship, a dual and bilateral influence was found. Finally, the structuring level of the organizational field has been also identified as low, which gives a chance to organizational actors of acting independently
Alguns autores t?m apontado para a necessidade de se compreender o processo de estrutura??o tecnol?gica nas empresas contempor?neas. Nesta perspectiva, a ind?stria de software tem tido papel fundamental, pois fornecem produtos e servi?os diretamente vinculados ? estrutura??o tecnol?gica de organiza??es das mais diversas ?reas de atua??o. No caso, a ind?stria brasileira de software apresenta algumas particularidades que a diferenciam de outras ind?strias situadas em pa?ses centrais, o que torna seu entendimento ainda mais relevante. H? evid?ncias de que as empresas nacionais assumem configura??es estruturais e estrat?gicas diferenciadas para ocupar esse mercado naturalmente dominado por empresas multinacionais de grande porte. Por essa raz?o, a presente tese tem como objetivo compreender n?o s? as configura??es assumidas pelas empresas nacionais de desenvolvimento de software, como tamb?m a din?mica e o processo que as levam a tal estrutura??o. Para isso, a pesquisa investiga o ambiente institucional, suas entidades e, consequentemente, os movimentos isom?rficos associados ? ind?stria de software, empregando um estudo, fundamentalmente, qualitativo, explorat?rio, descritivo e explicativo, atrav?s da estrat?gia de estudo de m?ltiplos casos. Foram feitas visitas t?cnicas ? 8 empresas do polo de tecnologia da informa??o da regi?o metropolitana de Recife, sendo aplicado um formul?rio e realizada uma entrevista com profissional em cargo de destaque dentro de cada empresa. Apesar de o estudo ser, predominantemente, qualitativo, parte dos dados coletados foi processada atrav?s de tabelas e gr?ficos, fornecendo uma vis?o geral das empresas e do ambiente investigados e subsidiando as an?lises em profundidade feitas a partir da interpreta??o do conte?do obtido com as entrevistas. Como resultado, pode-se dizer que as empresas se estruturam em torno de modelos de neg?cio h?bridos provenientes de dois tipos ideais de empresas de desenvolvimento de software, quais sejam: f?brica de software e empresa de base tecnol?gica. No que diz respeito ao processo produtivo, verificou-se que existe uma distribui??o equilibrada entre o paradigma de desenvolvimento tradicional e o ?gil. Dentre as metodologias tradicionais, a Rational Unified Process (RUP) ? a predominante. J? a metodologia Scrum ? a mais empregada entre empresas estruturadas a partir dos princ?pios do manifesto ?gil. Quanto ao processo de estrutura??o, foi encontrado que as entidades presentes no ambiente institucional atuam de forma diferente umas das outras, gerando for?as isom?rficas distintas e com variada intensidade. Destaque deve ser dado ?s entidades como clientes, ?rg?os de fomento ? pesquisa, arranjos produtivos locais, empresas l?deres de mercado, universidades p?blicas, incubadoras, entidades setoriais, fornecedores de tecnologia para o desenvolvimento de software e escola de forma??o e o background dos gestores, pois esses mant?m estreita rela??o com a estrutura??o das organiza??es investigadas. Acerca dessa rela??o, pode-se dizer que existe dualidade, tornando bilateral o tr?nsito de for?as isom?rficas. Por fim, constatou-se que o campo organizacional identificado ainda possui baixo n?vel de estrutura??o, o que abre espa?o para a a??o aut?noma dos atores organizacionais e, consequentemente, para as empresas de desenvolvimento de software

Повний текст джерелаOs dispositivos computacionais estão se tornando ubíquos. Com um celular, atualmente, podemos acessar e manipular informação praticamente em qualquer lugar e a qualquer instante. Neste cenário de computação ubíqua, tem-se exigido que tais sistemas sejam adaptativos, ou seja, tenham a capacidade de se adaptar em decorrência de mudanças no contexto em que estão inseridos. É importante destacar, porém, que a adaptabilidade adiciona certa complexidade ao desenvolvimento de aplicações. Um dos problemas é que a implementação de comportamentos adaptativos em muitos casos se entrelaça com outras preocupações da aplicação, como apresentação, negócio e dados, levando a problemas de legibilidade que podem prejudicar a manutenabilidade do código. A programação orientada a aspectos pode ser usada para facilitar a resolução de problemas relacionados a código entrela¸cado, e dar suporte ao desenvolvimento de programas adaptativos, e ao mesmo tempo adaptáveis (fáceis de modificar) com bons níveis de qualidade e produtividade. Essa dissertação mostra como podemos usar aspectos, em especial em AspectJ, para estruturar aplicações adaptativas, minimizando dessa forma o entrelaçamento de código. AspectJ é uma linguagem orientada a aspectos, de propósito geral, e que estende a linguagem Java. Ela é voltada `a separação de preocupações. Em nosso trabalho ela é utilizada para promover a separação da preocupação adaptabilidade , obtendo-se assim uma implementação modular. Através do uso dessa linguagem, identificamos boas práticas para a estruturação de aplicações adaptativas, as quais foram resumidas em um padrão denominado Adaptability Aspects. Escolhemos a plataforma Java 2 Micro Edition para implementar várias preocupações relativas a adaptabilidade, principalmente pelo fato de ser uma tecnologia destinada a dispositivos ubíquos e com recursos limitados. Al´em de AspectJ, analisamos também uma outra abordagem para a estruturação de aplicações adaptativas: o uso do estilo arquitetural denominado Adaptive Object- Models . Verificamos a partir dessa análise que ele poderia ser combinado com o nosso padrão, e portanto, beneficiar-se com o uso de aspectos. Dessa forma, poderia-se oferecer suporte a um conjunto maior de adaptações e ao mesmo tempo obter-se uma estrutura ção no código mais fácil de compreender. Por fim, avaliamos o impacto de AspectJ, através do uso do padrão Adaptability Aspects, para implementar alguns requisitos de adaptabilidade em aplicações J2ME. Comparamos nossa implementação com uma solução em que a implementação destes requisitos não é tão modular e com uma outra solução utilizando padrões de projeto puramente orientados a objeto na qual se buscava tal modularidade. Alguns dos aspectos comparados foram tempo de execução, memória utilizada, tamanho da aplicação e de seu código. Além de medir tais fatores, descrevemos os ganhos que a programação orientada a aspectos pode trazer para a estruturação de aplicações adaptativas visando obter qualidade em termos de reuso e facilidade de manutenção

Повний текст джерелаCompetence-cell based (regional) networks put special requirements on the modelling, planning and design of logistics structures. For the modelling of logistics structures, a generic description framework for production logistic sociotechnical systems, definitions for, amongst others, the central term logistics structure as well as a 3-layer-model and structure types for a more detailed material flow analysis and synthesis are provided. For the planning of logistics structures, the Method of Integrative Process and System Structuring (IPSS) is developed as a method for handling structuring problems. It can be applied especially to Competence-cell based networks as well as generally to production and logistics systems. For the design of logistics structures, scenarios as well as design and preference solutions for the material flow are derived

Повний текст джерелаThis work focuses on the improvement of the antennas compactness used primarily for embedded systems while respecting the performance and competitiveness requirements. The approach explored consists in using artificial materials operating in transmission and designed by structuring the dielectric material on a scale smaller than the wavelength (sub-wavelength). This structuring makes it possible in practice to achieve a variation in the effective refractive index in order to produce diffractive elements capable of performing a microwave function. However, the particularity of this type of structured element is to mix several physical scales generating complexity in their study. The largest dimension of a structured component can reach several tens of wavelength, for example 20λ, while the minimum size of the sub-wavelength structures may be less than a fraction of the wavelength, as than λ / 20. This multi-scale aspect increases the simulation times of antenna devices integrating these structured elements, thus preventing any possibility of multi-parameter optimization in reasonable times. In order to exploit fully the potential of these structured materials, a numerical model of computation has been developed on the basis of optical paths. This model gives results on the maximum gain of structured diffractive lens antennas with an accuracy of 0.5 dB. The computation time of the model is of the order of the minute compared to more than 6 hours for a complete simulation with the electromagnetic calculation software CST Microwave Studio. The speed and precision of this model have been used to optimize the design of a structured diffractive lens. To illustrate the relevance of this structured approach, its performances were compared with those of Fresnel lens antenna and hyperbolic lens antenna. This comparison was carried out under identical footprint conditions with a length to diameter ratio L / D of 0.5. The gain of the structured lens was found to be 1.6 dB higher than the Fresnel lens and 2.7 dB higher than the hyperbolic lens

Повний текст джерелаPretopology is a mathematical theory whose goal is to relax the set of axioms governing the well known topology theory. Weakening the set of axioms mainly consists in redefining the pseudo-closure operator which is idempotent in topology. The non-idempotence of the pretopological pseudo-closure operator offers an appropriate framework for the modeling of various phenomena, such as iterative processes evolving throughout time. Pretopology is the outcome of the generalisation of several concepts, amongst topology but also graph theory. This thesis is divided in four main parts. The first one is an introduction to the theoretical framework of the pretopology, as well as an overview of several applications in domains where the pretopology theory shines, such as machine learning, image processing or complex systems analysis.The second part will settle the logical modeling of pretopological spaces which allows to define pretopological spaces by a logical and multi-criteria combination. This modeling enables learning algorithms to define pretopological spaces by learning a logical formula. This part will also present an unrestricted pretopological spaces learning algorithm. Unrestricted pretopological spaces can be quite hard to manipulate, especially when the studied population has some structural properties that can be described in a more restricted space. This is why the third part is dedicated to the automatic learning of pretopological spaces of type V. These spaces are defined by a set of prefilters which impose a particular structure. The LPSMI algorithm, which is the main contribution of this work, is presented in this part. This algorithm relies on the multi-instance learning principles to accurately capture the structural properties of pretopological spaces of type V. Finally, the last part consists of multiple applications of the theoretical framework presented in this thesis. Applications to lexical taxonomies extraction, community detection and extraction of temporal relations, as part of a NLP process, will be presented in order to show the usefulness, the relevance and the flexibility of pretopological spaces learning

Повний текст джерелаThe structuring of water molecules at the water/vapour interface is an object of scientific interest for decades. Most of the existing theoretical studies are focused on bulk water but there is still need of a more detailed research on surface water. In addition, interfaces with alkanes are interesting as being instructive from both biological and industrial perspectives. Since in both bio- and industrial applications water/air and water/oil interfaces are mediated by amphiphiles, the role of a surfactant monolayer on surface water structuring deserves more attention as well.In the present Ph. D. thesis several atomistic water models were chosen and classical molecular dynamics simulations were carried out on bulk water, water/vapour and water/alkane (from pentane to nonane) systems, as well as on water/DLPC/vapour and water/DLPC/octane models, DLPC being dilauroyl phosphatidylcholine. In all cases the temperature was kept at 298 K. Several structural properties of bulk and surface water layers were examined by means of radial distribution functions and Voronoi diagrams. Dipole moments, surface tension and hydrogen bonding were tackled too. The objective was to estimate the impact of accounting for polarisability on the water properties of interest and to select a cost-efficient water model for describing them, as well as to add new data to the existing knowledge about interfacial water structuring.The study addresses the water structuring in bulk and surfacial water at the interface with vapour or alkanes of different chain length. One of the aims of the work was to assess the reproducibility of experimental data using an assortment of polarisable and non-polarisable water models and to check for which properties the utilisation of polarisable models is critical. Simple polarisable models based on Drude oscillators were tested in order to keep the computational costs low. For bulk water and water/vapour systems the models TIP4P, SWM4-NDP and COS/G2 performed the best. Since the TIP4P model produced results commeasurable with the polarisable ones, it was used predominantly further on to simulate water/alkane (C5-C9) interface and to quantify the structural parameters of water obtained from RDFs and Voronoi analyses. The molecules in this layer are organised in a more compact and less ordered manner. The ordering is owed mainly to hydrogen bonds which are twice as many in the bulk compared to the surface. The analysis of the Voronoi diagrams showed that the tetrahedral coordination was blurred and more complex polyhedra were formed. The surface layer was found to consist of two sublayers, inner and outer, with oppositely oriented unequal polarity, defining areas of residual charges at the interface.In addition to the systems with direct contact between water and non-polar fluids, interfaces mediated by lipid monolayers were modelled. The monolayer was meant to seam together the two phases. The compactness of the surfacial water, which was enhanced by the presence of alkanes, was tightened further by the lipid introduction. However, the water orientation was changed and the surfacial polarity was inverted, balanced by the lipid heads instead of the diffuse outer sublayer.The main contributions of the Ph.D. thesis are as follows:1. It is shown that the usage of a polarisable water model is not necessary for correct evaluation of a number of properties, but is critical for characteristics such as dipole moments and surface tension.2. For the first time a structural analysis has been made using Voronoi diagrams and an assortment of water models which demonstrates the difference between bulk and surfacial characteristics of liquid water.3. An original contribution is the study of a solid-condensed DLPC monolayer at the water/vapour interface utilising different water models and at the interface of water/octane, considering the limited experimental data available

Повний текст джерелаIn the context of passive damping, various mechanical systems from the space, aeronautic or auto-mobile industry use elastomer components (shock absorbers, silent blocks, flexible joints...).These materials have frequency, temperature and amplitude dependentcharacteristics. The associated numerical models may become computationally too expensive during an optimization process.The aim of this work is to propose an efficient reduced model of rubber devices that account for the viscoelastic damping and the non-linear pre-stress in the dampers.The first part of this thesis is about how to include the viscoelasticdamping in the reduced model. It starts by using a viscoelastic constitutive relation, based on experimental identification, within the frame of the finite element method to obtain a numerical model of the rubber dampers. A first efficient reduced model is then derived from this FE model by using an original extension of sub-structuring methods in the case of viscoelastic damping.In the second part, the influence of non-linear static pre-stress overthe dynamic behavior and the dissipation in the dampers is studied. An hyper-visco-elastic constitutive relation, linearized in the neighbourhood of a pre-stressed state, is developed. The sub-structuring methods presented in the first part are then upgraded to account for the damping and the geometrical non-linearities in the dampers. Finally, these 2-node reduced models give access to greatly reduced computation times (50 to 100 times faster) and are easy to use for the engineer

Повний текст джерелаBiofuels have renewed a strong development since 2000 in West Africa countries without a clear and shared vision by all stakeholders. However, the strategies and interactions between public and private actors are important in the construction of these biofuels sector and policies. The purpose of this thesis is to analyze public action described as "all relations [stakeholder's interplay] more or less institutionalized, practices and representations that contribute to the production and regulation of social relations" in the development of biofuels in Burkina Faso. It analyzes the influence of stakeholder's interplay in the emergence and structuring of several biofuels sectors and policy development. This thesis has also sought to analyze the influence of actors perceptions and interactions in the construction of institutional arrangements and sector governance. Finally, from a multi-criteria analysis based on the actors perceptions on potential structuring effects of biofuels in Burkina Faso development, it was highlighted the influence of these perceptions in explaining the current institutional landscape

Повний текст джерелаNowadays, automatic identification of plant species, by image analysis, has become crucial to maintain, standardize or deepen knowledge about the plant community. This thesis focus on the problem of automatic identification of plant species using leaf images. It addresses two main challenges: The first challenge is the large number and the high variability in foliar morphology across species. The second challenge is the intra-species variability which occurs locally at particular regions of leaves. To overcome these two problems, a return to botany and especially to leaf botanical concepts is established in order to define an automatic structuring of leaves at two levels: The first level concerns a categorisation scheme according to the botanical concepts “arrangement” and “lobation". The second level consists in decomposing leaves into semantic parts. The approach of the thesis is based on two key parts: In the first part, we focus on establishing this botanical-based structuring process by defining simple geometric properties correlated with botanical definitions and observations. In the second part, we investigate the feasibility and opportunities to integrate this structuring process in the identification scheme. Particularly, we make targeted researches in categories and we define specific part-based models.Experiments are conducted using the ImageCLEF 2011 and 2012 Scan images leaf databases. We compare our approach with respect to the reference identification scheme, applied on the whole databaseand using the entire images, and with respect to several methods referenced in the literature

Abstract: The Analytic Hierarchy Process (AHP) and its general form, Analytic Network Process (ANP), help decision makers understand real world problems and solve them via a hierarchical or network structure. It has been popular for many business applications and has become an important technique in multiple criteria decision making. This study proposes two kinds of improvement processes of model-structuring and applies them to the selection of the appropriate green supply chain management (GSCM) strategy and the evaluation of consumers’ acceptance of wearable technology. First, the researcher organized the GSCM strategy-selection network structure according to the product lifecycle management (PLM) concept. Then the importance of control criteria which could make the results of pair-comparisons more precise was stressed and the GSCM strategy which conformed to the environmental perspective kept by the organization was chosen. Then the study selected a leading Taiwanese electronics company to demonstrate how to choose an appropriate GSCM strategy via the proposed model. The analytical results derived from the model can provide suggestions for departments’ policies or programs since the concept of PLM corresponds with their business functions/departments types. In addition, the Unified Theory of Adoption and Use of Technology (UTAUT) model which is a more robust theory model and used commonly to predict the acceptance of a new technology was utilized to be a basis for an analytical network-framing. Then, wearable technology was taken an example to evaluate customers’ intention to use the products and the level-low, medium and high of actual use of wearable technology in Taiwan. This approach not only improved the model-framing objectivity; but also avoided some limitations which existed in statistical methods including some assumptions, problems with sample sizes and so on. The method used in this study allowed for issues related to inaccurate statistical significance magnitude resulted from different samples which keep users from understanding the importance of each variable to be avoided. The stability of the above tow model-structuring approaches was confirmed via sensitivity analysis; however, the first approach which is based on managerial concepts should combine other mathematical techniques to show better judgments in relationship–linking between each factor. The other approach which is based on UTAUT model also continuously examined the feasibility of other theoretical models, and then advanced to a more objective and feasible transferring process.

It unlocks the potential of molecular orientation for the achievement of a range of enhanced physical properties. We provide here an overview of techniques developed in our laboratories for structuring polymers by solid phase orientation processing routes, with a particular focus on die drawing, which have allowed control of significant enhancements of a single property or combinations of properties, including Young's modulus, strength, and density. These have led to notable commercial exploitations, and examples of load bearing low density materials and shape memory materials are discussed.

In order to improve the development of new products, such as the pre-operational phase of uncertainty across functional departments, the goal is inconsistent, the lack of effective messages and unstable situations such as decision-making efficiency, the need to improve the efficiency of preliminary work for the stage. Because of defense industries have the special nature of its products and customers, development of new products early in session, "Product-Service Integration", "Co-development" and "customer involvement" are the three related aspects of early development stages while the defense industries have difference with other civil manufacturing. The purpose of this study to explore new product development through early stages of the relevant academic literature, reference technology integration planning process and project documents, the "integration of products and services," "customer involvement" and "open innovation model of cooperation," the three level of integration, the district is divided into three phases, "opportunity identification", "conceptual development" and "project screening", in order to construct the way that products and services were integrated in IDEF0 system. Defense industry organizations could develop pre-processes, and explore the process to construct on the feasibility of applying with practice

Повний текст джерелаIn social face perception research, trustworthiness and dominance were found as the core dimensions underlying personality impressions based on facial appearance. These dimensions bear a striking resemblance to dimensions found in the parallel domain of person perception research such as the warmth and competence or communion and agency dimensions of personality impressions based on verbal person descriptions (e.g., trait-based descriptions). Given that both types of social information often co-occur in real social interactions and guide social decision making, it becomes crucial to understand how impressions derived from both sources are interrelated. Yet, so far, questions regarding the extent to which the dimensions of social face perception overlap with the dimensions of person perception, and regarding the nature and direction of the interrelationships between these dimensions, have been largely overlooked in the literature. The main goal of this thesis was to fill this gap in the literature and make initial steps towards the integration of social face perception and person perception models of personality impressions. In the first paper, a reverse correlation methodology was used to assess the extent to which dimensions of social face perception were perceived to overlap with dimensions of person perception by perceivers themselves. The results showed that dimensions establishing opposite relationships with valence, such as dominance and competence, were perceived as less similar than dimensions establishing a common positive relationship with valence, such as trustworthiness, warmth, and competence. These findings clarified that the dimensions of facial impressions and of person perception are not always perceived as redundant, and further highlighted the role of valence in shaping the relationship between dimensions across domains. The second paper employed a paradigm designed to directly assess the nature of the relationship that valence establishes with the core dimensions of social face perception and person perception. The results revealed that ability-related trait dimensions such as competence and dominance exhibited more variability in the nature and direction of their relationship with valence, comparatively to dimensions related with morality and warmth. These findings further emphasized that the overlap or dissociation between core dimensions of social judgment is largely driven by the features of the relationship they establish with valence. The third paper focused exclusively on social face perception and used a reverse correlation methodology to investigate how trustworthiness and dominance are naturally integrated into unitary impressions of facial appearance. The results showed that the dimension more strongly related with valence—trustworthiness—outweighed dominance in the resulting impressions of facial appearance. These findings highlight the primary role of valence information in shaping how dimensions are integrated within social face perception. Overall, these findings highlight the primary role of valence in structuring the relationship between dimensions of social judgment, not only across models of person perception and social face perception, but also within each model. Moreover, they offer a clearer picture on the relationship and integration of models of social face perception and person perception, and lay out clear new directions for future research on social perception in general.
Na investigação em perceção social de faces, confiabilidade e dominância emergiram como as principais dimensões subjacentes às impressões de personalidade baseadas em aparência facial. Estas dimensões assemelham-se bastante às encontradas no domínio paralelo de perceção interpessoal, como as dimensões de simpatia e competência, ou communion e agência, que subjazem impressões de personalidade baseadas em descrições verbais de pessoas (e.g., baseadas em traços). Dada a coocorrência de ambos os tipos de informação na maioria de interações sociais reais, e o seu impacto na tomada de decisões sociais, torna-se crucial compreender como as impressões derivadas de ambas as fontes de informação se interrelacionam. Porém, o grau de sobreposição entre as dimensões da perceção social de faces e da perceção interpessoal, assim como a natureza e direção das inter-relações entre essas dimensões, têm sido questões amplamente negligenciadas na literatura. O principal objetivo desta tese foi preencher essa lacuna na literatura e dar os primeiros passos em direção à integração dos modelos de impressões de personalidade associados à perceção social de faces e à perceção interpessoal. No primeiro artigo, métodos de reverse correlation foram implementados para avaliar em que medida as dimensões da perceção social da face se sobrepõem às dimensões da perceção interpessoal na perspetiva dos próprios percipientes. Os resultados mostraram que as dimensões exibindo relações opostas com valência, como dominância e competência, foram percebidas como menos semelhantes entre si comparativamente às dimensões partilhando a mesma relação (positiva) com a valência, como confiabilidade, simpatia, e competência. Estes achados esclareceram que as dimensões de impressões faciais e da perceção interpessoal nem sempre são percebidas como redundantes, e destacam o papel da valência na estruturação das relações das dimensões entre os dois domínios de investigação. No segundo artigo, desenvolveu-se um paradigma para avaliar diretamente a natureza da relação que a valência estabelece com as dimensões centrais das impressões faciais e da perceção interpessoal. Os resultados revelaram que as dimensões de traço relacionadas com habilidade, como competência e dominância, exibiram maior variabilidade na natureza e direção da sua relação com valência, comparativamente às dimensões relacionadas com moralidade e simpatia. Estes achados enfatizaram ainda que a sobreposição, ou dissociação, entre as dimensões é amplamente promovida pelas características das relações destas com valência. O terceiro artigo focou-se exclusivamente na perceção social de faces, e utilizou métodos de reverse correlation para investigar como a confiabilidade e a dominância são naturalmente integradas em impressões unitárias de aparência facial. Os resultados mostraram que a dimensão mais fortemente relacionada com valência—confiabilidade—teve maior peso que dominância nas impressões faciais. Estes achados destacam o papel primário da valência na integração de dimensões em impressões faciais. No geral, estes achados destacam o papel primário da valência na estruturação das relações entre dimensões de julgamento social, não apenas entre os modelos de impressões faciais e de perceção interpessoal, mas também dentro de cada modelo. Além disso, oferecem uma visão mais clara sobre a relação e integração destes modelos, e traçam direções claras para futuras investigações no domínio geral da perceção social.

Повний текст джерелаChildhood obesity is a remarkable social reality in contemporary societies. It articulates with the social relations that promote individualization and culpability of children and families, from the deposited beliefs in the biomedical model in which nutrition and physical activity are the main exponents of a paradigm based on the consideration of obesity as “disease”, in the possibilities of “cure” it, and in the urgency to fight against this new “epidemic”. There is an urgent need for understanding the social complexities inherent to obesity, namely to childhood obesity, which are nowadays predominantly represented as important social problems. For such, it was essential to proceed to the construction of a sociological model that did emerge the settings and social dynamics of childhood obesity involved in its causes and consequences. By the use of methodological triangulation it was revealed the importance of historical and civilizational present in interactions and social roles, with implications on socialization processes responsible for the formation of provisions, and ways children think and act. The family appears as a central institution in this phenomenon, not only in the social reproduction of lifestyles, but mainly for its structure and dynamics of social relations. In the rise of childhood obesity are transformations in stable social relationships in the form of changes in daily life, family transitions or biographical crisis. Self-esteem, emotional and psychological situation, resilience ability and different forms of social integration in the face of these changes affect the emergence of childhood obesity. This survey allowed the construction of a sociological model and a social intervention model focused on childhood obesity, which it is believed that may be replicated in other territorial contexts.
