The increased importance of social media influencers in marketing activities has been evident in recent years. The purpose of the thesis was to understand the cognitive processing of social media micro influencers’ content and the resultant behavioral outcome of follower engagement and purchase intention. Specifically, it has aimed to evaluate if the format of the content had an impact on cognitive processing and ascertains the resultant outcomes of engagement and purchase intention. Elaboration likelihood model (ELM) adapted to social media, was used, and adopted in the study in order to understand and evaluate the purpose as well as the information process of individuals. The research was narrowed down to the micro-influencers in the fashion and beauty industry sharing content, as the industry's high usage of influencer marketing and disseminating persuasive messages on Instagram. The research was conducted by using the Experimental Vignette Methodology (EVM) in a quantitative experiment. By doing so, it enabled the research to examine the participants' response to natural stimuli with quantitative results. A questionnaire together with exposure to three stimuli were used as instrumental in the collection of data. The sample was collected through social media platforms, mainly Instagram and Facebook, and via email to the students of LTU. The collected data was later analyzed, through SPSS, in two levels: impact and hypothesis testing. The impact measurement was analyzed by using repeated measures ANOVA and later the multilinear regression analysis to test the independent variables of content format relation to the dependent variables of engagement (comment and like) and purchase intention (tendency and likelihood). The findings indicated a support to the existing theory of ELM, by confirming the importance of the argument quality in the persuasive message. High lighting in the importance of text content format,in both engagement via commenting and purchase intention, when the information is processed through the more long-lasting central route. The results contributed to current literature in micro influencer and social media influencer marketing by extending the literature in persuasive messaging in relation to the content format. The research provided practical implications with insights into the cognitive processing of content and its implications in consumer engagement and purchase intention to both managers as well as to the content providers, social media influencers. The study presented relative information for content creation, communication and opened possibilities for further research in persuasive messaging in the micro media influencer segment.

News has been criticised for being fake and promoting echo-chambers. At the same time, spatial technologies have become more accessible, enabling affordable virtual reality (VR) and augmented reality (AR) systems. These systems enable a new channel for interfaces and content. Can these technologies establish a connection between space and news, resulting in a stronger connection between viewers and the news? We address these questions by building tools for news production and content consumption that use spatial technology. Through user-tests we show that spatial-organization of news information can result in greater news exposure. We evaluate spatial production tools by creating three live-broadcasts in VR and comparing them to broadcasts done by a production team. We also show that users have a bimodal response to 2.5D videos shown in AR. This thesis presents and evaluates a series of interactive spatial experiences to address the potential for spatial technologies for media-based journalism.

Jeong, Ki Tai. „A Common Representation Format for Multimedia Documents“. Thesis, University of North Texas, 2002. https://digital.library.unt.edu/ark:/67531/metadc3336/.

Annotation:

Multimedia documents are composed of multiple file format combinations, such as image and text, image and sound, or image, text and sound. The type of multimedia document determines the form of analysis for knowledge architecture design and retrieval methods. Over the last few decades, theories of text analysis have been proposed and applied effectively. In recent years, theories of image and sound analysis have been proposed to work with text retrieval systems and progressed quickly due in part to rapid progress in computer processing speed. Retrieval of multimedia documents formerly was divided into the categories of image and text, and image and sound. While standard retrieval process begins from text only, methods are developing that allow the retrieval process to be accomplished simultaneously using text and image. Although image processing for feature extraction and text processing for term extractions are well understood, there are no prior methods that can combine these two features into a single data structure. This dissertation will introduce a common representation format for multimedia documents (CRFMD) composed of both images and text. For image and text analysis, two techniques are used: the Lorenz Information Measurement and the Word Code. A new process named Jeong's Transform is demonstrated for extraction of text and image features, combining the two previous measurements to form a single data structure. Finally, this single data measurements to form a single data structure. Finally, this single data structure is analyzed by using multi-dimensional scaling. This allows multimedia objects to be represented on a two-dimensional graph as vectors. The distance between vectors represents the magnitude of the difference between multimedia documents. This study shows that image classification on a given test set is dramatically improved when text features are encoded together with image features. This effect appears to hold true even when the available text is diffused and is not uniform with the image features. This retrieval system works by representing a multimedia document as a single data structure. CRFMD is applicable to other areas of multimedia document retrieval and processing, such as medical image retrieval, World Wide Web searching, and museum collection retrieval.

This study was designed to determine (1) the level of priority that employees of nonprofit counseling agencies affiliated with the National Foundation for Consumer Credit (NFCC) feel the topics of credit, personal finance, investments, counseling, and consumer education should be given on a national certification examination for financial counselors, and (2) to determine the viewpoints of NFCC counselors concerning the format of a national certification examination.

Data were collected with a 162-item questionnaire from 281 individuals employed by nonprofit counseling agencies affiliated with the NFCC; this represented an 83% response rate. Respondents were asked to prioritize 138-items on a scale of 1 for low priority to 5 for high priority. The items were distributed unevenly among the five topic areas.

The overall mean priority score of all five topic areas was 3.6. Credit and counseling both received the highest individual topic mean priority score of 4.1.

Annotation:

BACKGROUND:Patients receiving complementary and alternative medicine (CAM) therapies often report shifts in well-being that go beyond resolution of the original presenting symptoms. We undertook a research program to develop and evaluate a patient-centered outcome measure to assess the multidimensional impacts of CAM therapies, utilizing a novel mixed methods approach that relied upon techniques from the fields of anthropology and psychometrics. This tool would have broad applicability, both for CAM practitioners to measure shifts in patients' states following treatments, and conventional clinical trial researchers needing validated outcome measures. The US Food and Drug Administration has highlighted the importance of valid and reliable measurement of patient-reported outcomes in the evaluation of conventional medical products. Here we describe Phase I of our research program, the iterative process of content identification, item development and refinement, and response format selection. Cognitive interviews and psychometric evaluation are reported separately.METHODS:From a database of patient interviews (n = 177) from six diverse CAM studies, 150 interviews were identified for secondary analysis in which individuals spontaneously discussed unexpected changes associated with CAM. Using ATLAS.ti, we identified common themes and language to inform questionnaire item content and wording. Respondents' language was often richly textured, but item development required a stripping down of language to extract essential meaning and minimize potential comprehension barriers across populations. Through an evocative card sort interview process, we identified those items most widely applicable and covering standard psychometric domains. We developed, pilot-tested, and refined the format, yielding a questionnaire for cognitive interviews and psychometric evaluation.RESULTS:The resulting questionnaire contained 18 items, in visual analog scale format, in which each line was anchored by the positive and negative extremes relevant to the experiential domain. Because of frequent informant allusions to response set shifts from before to after CAM therapies, we chose a retrospective pretest format. Items cover physical, emotional, cognitive, social, spiritual, and whole person domains.CONCLUSIONS:This paper reports the success of a novel approach to the development of outcome instruments, in which items are extracted from patients' words instead of being distilled from pre-existing theory. The resulting instrument, focused on measuring shifts in patients' perceptions of health and well-being along pre-specified axes, is undergoing continued testing, and is available for use by cooperating investigators.

Annotation:

The purpose of this research was to provide a better understanding of handbooks and to establish criteria guidelines for handbook selection and use. Content analysis utilizing the library as fieldwork identified 15 handbooks for MsWs meeting selection criteria for this study. Coding and diagramming of over 2000 pages resulted in identification of 15 themes which grouped into 3 types of relationships: personal (to self and God), familial (to husband and children), and congregational (to the church). Six of these themes were recognized as distinctive to the life of the MsW. Three time frames (1940 to 1960, 1960 to 1980, and 1980 to 1998) were established, and handbooks were found to be consistent with the social context of their respective era. An unfolding picture of the life of the MsW as portrayed by key informants revealed a shift in emphasis, with earlier handbooks portraying a lifeworld revolving around role fulfillment, and later handbooks emphasizing development as a person. A lack of learning opportunities for MsWs was noted throughout the eras. A 30+ page appendix of metaphors indicates that MsWs use their gift of reasoning through word pictures. The authors taught lived world truth as they perceived it. This study indicated clues as to appropriateness of content in handbooks and safeguards to be taken in reading them for self-directed learning or other training purposes. The implication is that handbooks are adult education by default. Two original products resulting from this research were a schemata of the process of using handbooks as a format for learning and selection criteria guidelines for choosing a handbook. The process may be utilized in self-directed learning (individual or guided) and within other educational settings, and the guidelines may be adapted to handbooks for other populations. This research should encourage related studies to broaden the knowledge base of understanding handbooks and recognizing their place in training, utilizing field research using literature sources, and assisting MsWs with learning how to effectively manage their myriad roles and relationships.

A agricultura demanda grande quantidade de água para a produção de alimentos e fibras. Técnicas que determinem e monitorem a dinâmica da água no solo são importantes para promover o uso correto e consciente desse recurso natural. Diante do exposto, a tensiometria é uma ferramenta eficiente na determinação da dinâmica da água em solos agrícolas, podendo ser utilizada em conjunto com sensores de capacitância para a caracterização da curva de retenção de água no solo. Contudo, apesar de práticos, erros associados à instalação e às características das cápsulas podem comprometer a precisão dos tensiômetros. Esse trabalho teve como objetivo testar a influência do uso de lama de solo no momento da instalação, bem como o formato e condutância hidráulica de cápsulas de tensiômetros de punção sobre o potencial matricial da água no solo, tendo-se como referência tensiômetros com manômetro de mercúrio. Também, se objetivou determinar a curva de retenção de água no solo com base nos dados obtidos por tensiometria e de um sensor de capacitância. Os resultados mostram que o formato das cápsulas de cerâmica e a lama de solo influenciaram as determinações do potencial matricial, ao contrário da condutância hidráulica das cápsulas. A lama de solo é indicada na instalação de tensiômetros com manômetro de mercúrio e de punção. As curvas de retenção diferiram quanto aos sistemas de aquisição (manômetro de mercúrio ou tensímetro); no entanto, o modelo ajustado não foi sensível em distinguir diferenças entre os tratamentos quanto ao formato das cápsulas ou uso de lama de solo. De modo geral, ocorreu uma subestimativa dos ajustes das curvas de retenção para os tensiômetros de punção, o que pode levar a interpretações errôneas das curvas de retenção de água no solo quando determinadas por meio desses instrumentos.
The agriculture demand large amounts of water for food and fiber production. The techniques used to determine and monitor the water dynamics in the soil are important to promote the correct and conscious use of this natural resource. Given the above, the tensiometry is an efficient tool for the determination the water dynamics in soils, which can be used in conjunction with capacitance sensors to characterize the water retention curve in the soil. However, although practical, errors associated with the installation and the characteristics of the capsules may compromise the accuracy of tensiometers. This study aimed to test the influence of the use of soil slurry during the tensiometer installation, the format and hydraulic conductance of the capsules from puncture tensiometers on the matric potential of soil water, taking as reference tensiometers equipped with mercury manometers. In addition, aimed to determine the soil-water retention curve based on data obtained by tensiometry and a capacitance sensor. The results shows that the format of the ceramic capsules and the use of the slurry influenced the measurements of matric potential, as opposed to hydraulic conductance of the capsules. The soil slurry is recommended for tensiometers equiped with mercury manometer and puncture tensiometers. The retention curves differed among the acquisition systems (mercury manometer or tensimeter); however, the fitted model was not sensitive enough to distinguish differences between treatments for the format of the capsules or the use of soil slurry. In general, there was an underestimation of the retention curve for puncture tensiometers, which can lead to erroneous interpretations of the soil-water retention curve when determined by these instruments.

O presente trabalho tem como objetivo propor uma estrutura conceitual para análise de como se dá a relação entre as normas contratuais formais e relacionais na composição da estrutura de governança das relações interorganizacionais. A pesquisa foi fundamentada nas teorias dos Contratos Relacionais, na literatura de contratos formais em relações interorganizacionais e na Teoria Economia dos Custos de Transação. É argumentado que em diferentes contextos transacionais a função e o conteúdo dos acordos formais, bem como o conteúdo dos acordos relacionais diferem. Sendo a presente pesquisa qualitativa-exploratória, foram analisadas seis relações interorganizacionais, quais sejam: as relações de três empresas incubadas em diferentes estágios de incubação; a relação de uma empresa com o conglomerado formal do qual a mesma participa; a relação de uma empresa calçadista e seus fornecedores, sendo todos participantes de um conglomerado informal de empresas; a relação de uma usina e seus fornecedores de cana-de-açúcar, uma vez que estas relações tendem a ser de longa duração. Para aplicação da Análise do Conteúdo foram seguidas as fases de pré-análise, exploração do material, e tratamento dos resultados e interpretações conforme Bardin (2011). A partir do protocolo de coleta de dados, as entrevistas transcritas foram exploradas a partir das categorias do protocolo. Considerando as proposições elaboradas observou-se que as características contextuais \'incerteza\', \'dificuldade de mensuração de performance\' e \'especificidade de ativos\' corroboram a presença de maior formalidade contratual na relação nos casos extremos de menor e maior intensidade dessas características. Diferentemente, a característica de expectativa de continuidade aparece de maneira homogênea em todas as relações analisadas, não sendo possível indicar tal variável como tendo a função diferenciadora na composição contratual. Na análise dos aspectos exploratórios observou-se que fatores como troca de conhecimento, aprendizagem e manutenção de padrão de qualidade do recurso transacionado, o ciclo de vida da organização, a atuação em mercados internacionais e a cultura destes mercados para a negociação, o setor de atuação da empresa e a existência de diversidade em formas de obtenção de insumos, alteram a percepção de presença e intensidade das variáveis que determinam o contexto no qual as relações são governadas alterando, por sua vez, a composição da estrutura de governança destas relações. Também foi verificado que o ciclo de vida, o tamanho da empresa e o tipo de insumo transacionado, foram indicados como aspectos que alteram o padrão da relação no espectro relacional, indicando que tais fatores poderiam também compor o modelo de análise de conteúdo contratual proposto neste trabalho. No que se refere ao conteúdo relacional, não foi possível verificar homogeneidade na composição das normas relacionais utilizadas, indicando que, possivelmente, a alteração do contexto da relação influencia a intensidade com que as normas relacionais são utilizadas, corroborando para a hipótese desta pesquisa. Na análise do conteúdo contratual formal, suas funções e nível complexidade, verificou-se que, na presença de maior intensidade de incerteza, dificuldade da mensuração da performance e especificidade de ativos, a complexidade dos contratos formais tende a ser influenciada por estas características contextuais. Em se tratando das funções contratuais formais, destaca-se que, apenas nos casos em que há especificidade de ativos de maneira mais intensa, houve corroboração da função contratual de salvaguardar.
This paper aims to propose a conceptual framework for analyzing how is the relationship between formal and relational contracts in the composition of the governance structure of inter-organizational relationships. The research was based on the theories of Relational Contracts, in the literature of formal agreements on inter-organizational relationships and Theory Economics of Transaction Costs. It is argued that in different transactional contexts the function and content of formal agreements, as well as the content of relational agreements differ. As this is a qualitative exploratory study, we analyzed six inter-organizational relationships using the Content Analysis applied on collected and transcribed interviews, namely: the relationship of three companies incubated at different stages of incubation; the relationship of a company with the formal conglomerate which it participates; the relationship of a footwear company and its suppliers, which all share an informal group of companies; the ratio of a plant and its sugarcane suppliers, since these links tend to be long lasting. From elaborated propositions, it was revealed that the contextual characteristics \'uncertainty\', \'difficulty in measuring performance\' and \'asset specificity\' support the presence of more contractual formality in relation to extreme cases of lower and higher intensity of these characteristics. Unlikely, the continuity of expectation feature appears evenly in all analyzed relationships, not being possible to indicate such a variable as having a distinctive role in the contractual composition. In the analysis of exploratory aspects, it was observed that factors such as exchange of knowledge, learning and standard of maintenance quality transacted resource, the organization\'s life cycle, the performance in international markets and culture of these markets for trading, the sector the company operates, and the existence of diversity in ways of obtaining inputs, change the perception of presence and intensity of the variables that determine the context in which the relationships are governed changing, in turn, the composition of the governance structure of these relationships. It was also found that the life cycle, company size and type of traded inputs (i.e. presence / absence of technology and innovation in the contracted feature), were indicated as aspects that alter the pattern of the relationship in the relational spectrum, indicating that such factors could also compose the contractual content analysis model proposed in this paper. With regard to the relational content, it was not possible to verify the homogeneity in the composition of the relational rules used, indicating that, possibly, different contexts influence the intensity with which the relational rules are used, supporting the hypothesis for this study. In the analysis of the formal contract content, its functions and complexity level, it was found that in the presence of higher intensity of uncertainty, difficulty of measuring the performance and asset specificity, the complexity of the formal contract tends to be influenced by these contextual characteristics. In the case of formal contractual functions (i.e. safeguard, coordinate, adapt), it is emphasized that only in cases where there is intense asset specificity, there was corroboration of the contractual function of safeguarding.

Mestrado em Gestão de Recursos Humanos
Devido ao mundo global e às mudanças que este tem vindo a assinalar, um dos elementos chave para a vantagem competitiva das organizações que nele actuam é a criatividade, bem como o improviso. Nos últimos anos desenvolveram-se vários estudos sobre este mesmo tema, na área da gestão, que demonstram que essa vantagem competitiva ocorre quando a criatividade é abordada em função do seu contexto. Contudo, sendo a criatividade e o improviso inerentes ao ser humano, ambos também acabam por se manifestar em outras áreas da vida humana, como a música, a dança, o teatro e nomeadamente o desporto. Este trabalho visou perceber de que forma é que a criatividade e o improviso estão presentes no ténis de alta competição, como se manifestam, se é importante e sua existência, e que tipo de vantagens trazem para os jogadores. Teve como campo de estudo pessoas relacionadas com o ténis: jogadores, treinadores, árbitros e adeptos. Para a concretização dos objectivos previamente propostos, foram realizadas entrevistas de tipo semi-estruturadas, dirigidas presencialmente a 15 pessoas - 6 treinadores, 4 jogadores, 1 árbitro e 4 adeptos, tendo-se obtido uma taxa de 100% de participação. Estas entrevistas foram analisadas com base à técnica de análise de conteúdo temática (Bardin, 1977). Os resultados obtidos indicam que tanto a criatividade como o improviso estão presentes no ténis - talvez mais o improviso - sendo melhores descritos como identitários do ser jogador, ou seja, é necessário e importante que estas capacidades existam pois trazem vantagens aos jogadores.
Due to all the changes that happened on global world one of the key elements to have competitive advantage on organizations that act in it is: creativity and improvisation. In recent years we have developed several studies on this subject demonstrating that this competitive advantage occurs when creativity is addressed according to their context. However, with the creativity and improvisation inherent in the human being, eventually manifest itself in other áreas of human life, such as music, dance, theater and particulary sport. This study aim to understand how creativity and improvisation are present in top-level tennis, how are manifested, its importance and its existence, and what kind of benefits they bring to the players. It had as studie field people related to tennis: players, coaches, referees and fans. To meet the previously proposed objectives semi-structured type of interviews weres conducted in person addressed to 15 people - 6 coaches, 4 players, 1 referee and 4 fans, having obtained a rate of 100% stake. These interviews were analyzed using the thematic content analysis (Bardin, 1977). The results show that both creativity and improvisation are present in tennis - perhaps more improvisation - is best described as the identity of a player, and i tis necessary and important that these capabilities exist because they bring advantages to players.

Este estudo buscou investigar as possibilidades de promover mudanças nas práticas educativas de professoras de berçário de um Centro de Educação Infantil da Rede Municipal de Educação da Cidade de São Paulo, através de um processo de formação em contexto centrado na escola. A identidade do professor de educação infantil vem se construindo gradativamente à medida que também se reconstrói a identidade das instituições do tipo creche. Apesar de as ações pedagógicas nos Centros de Educação Infantil virem se ressignificando, ainda se observam posturas descontextualizadas, provavelmente em função de concepções e representações sedimentadas de infância e educação de crianças pequenas. De um modo geral, ainda não se constata uma prática que privilegie, de fato, a cultura infantil e que rompa totalmente com uma educação construída sob os moldes da cultura dos adultos. À luz das teorias de Vygotsky e Bruner e das formulações de Oliveira-Formosinho sobre formação em contexto de profissionais da educação infantil, a pesquisa envolveu um estudo de caso inspirado nos preceitos metodológicos da investigação-ação constando de um projeto de desenvolvimento profissional mediante uma parceria entre a pesquisadora, também diretora da unidade educacional, a coordenadora pedagógica e quatro professoras. O processo formativo, pautado em registros videográficos, promoveu revisões da ação docente e desencadeou reflexões sobre a constituição e organização do espaço de berçário, as diversas relações que nele acontecem e as mediações realizadas pelas educadoras envolvidas. Através da busca conjunta de soluções de problemas, não delimitados de antemão, foram emergindo novas concepções sobre a prática educativa e mudanças no teor das reflexões. A análise dos dados revelou que a formação em contexto, apesar de constituir-se em processo não linear, complexo e lento, pode revelar um tipo de formação eficiente para a promoção de conhecimentos e melhoria da prática, à medida que possibilita a reconfiguração do sentido e a ampliação do envolvimento e da responsabilidade dos participantes.
The present study aimed to investigate the possibilities of promoting changes in educational practices of nursery teachers in a Child Care in the municipality of São Paulo. This work is presented through a training process focused in Educational Centers. The identity of a teacher in the child upbringing has been built in the same context as Child Cares have. Despite the fact that pedagogic actions in Children Educational Centers have been changing consistently, there are still out of context attitudes related to concepts and representations arising from the childhood and education of small children. In general, it is hard to find a practice that focus the kinderculture and break with an education built under the form of an adult culture. In light of the theories by Vygotsky and Bruner, as well as the ones formulated by Oliveira- Formosinho about the training of child care professionals, this research includes a case study inspired by precepts that take into account an investigation-action methodology. That includes a professional development project that has been developed by this researcher (who is also the director of a child care), a pedagogic coordinator and four teachers from the same institution. The educational process that was guided by video records promoted a change in the action of the teacher, as well as some reflections about, among others, the structure and organization of the nursery, the interactions that happen in the same place, and the mediations among the teachers involved. Through a joint investigation of solutions for the issues mentioned above, that werent previously delimited, new conceptions of the educational practices and new elements to the discussions have emerged. The data analysis revealed that this kind of exercise, even though is a non linear, complex and slow process, can reveal a more efficient way to knowledge sharing and improvement of actions and practices in a way that provides the means to a new way of thinking and enlarging the participants responsibilities.

A model of access control aims to limit the actions that a User can have legitimate in a system. Its purpose is to improve security by ensuring the properties of integrity and confidentiality. The model of access control is considered standard based on profiles or roles. The profiles are functions that the User can exercise and access permissions to objects are associated with a profile according to their function. The model-based profiles can not take into account aspects of the environment where the access occurs, it limits the possibilities of establishing policies for the most comprehensive security accompanying the scenario of technological change. Models that extend the model-based profiles have been proposed, there are settings in them that make possible the mapping of the environment where the access occurs, also called context, however, there is no consensus on the representation of context and security policies demonstrated by definitions of these models are specific to their use cases. This work presents a model based access control in context expressions CABEC. This model has definitions based on models that extend the model based on profiles, however, shows the construction of security policies for different domains. Security policies built with the CABEC take into account dynamic information environment and their combinations. These aspects are important because they increase the wealth of security policies and flexibility in its construction. The dynamic aspects of context refers to information the moment of interaction, are given as time intervals, number of simultaneous access, physical access, location. The aspect of flexibility in policy construction comes from the possibility of the security manager to choose the amount of rules and combinations thereof, can build a policy that takes into account the rule of office hours combined with the role that the subject is exerting at the time, or simply considering a rule that takes into account only its location. With a model of access control that takes into account dynamic information and their combination increases the security and, consequently, the gain in productivity in relation to ownership of availability of services, data and computing resources.
Um modelo de controle de acesso tem o objetivo de limitar as ações que um usuário legítimo pode exercer em um sistema. Sua finalidade é melhorar a segurança garantindo as propriedades de integridade e confidencialidade. O modelo de controle de acesso considerado padrão é o baseado em perfis ou papéis. Os perfis são funções que o usuário pode exercer e as permissões de acesso a objetos são associadas a um perfil de acordo com a sua função. O modelo baseado em perfis não consegue levar em conta aspectos do ambiente onde ocorre o acesso, isso limita as possibilidades de construção de políticas de segurança mais abrangentes que acompanhem o cenário da evolução tecnológica. Modelos que estendem do modelo baseado em perfis foram propostos, neles existem definições que tornam possível o mapeamento do ambiente onde ocorre o acesso, também chamado de contexto, porém, não existe um consenso em relação à representação do contexto e as políticas de segurança demonstradas pelas definições desses modelos são específicas para seus casos de uso. Esse trabalho apresenta um modelo de controle de acesso baseado em expressões de contexto CABEC. Tal modelo possui definições baseadas nos modelos que estendem o modelo baseado em perfis, porém, demonstra a construção de políticas de segurança para domínios diferentes. As políticas de segurança construídas com o CABEC levam em consideração informações dinâmicas do ambiente e suas combinações. Esses aspectos são importantes, pois aumentam a riqueza das políticas de segurança e a flexibilidade na sua construção. Os aspectos dinâmicos do contexto se referem a informações do instante da interação, são dados como intervalos de tempo, quantidade de acessos simultâneos, meio físico de acesso, localização. O aspecto da flexibilidade na construção das políticas vem da possibilidade do gerente de segurança escolher a quantidade de regras e suas combinações, pode construir uma política que leve em conta a regra de horário de expediente combinada com a função que o sujeito está exercendo naquele momento, ou simplesmente considerar uma regra que leva em conta somente sua localização. Com um modelo de controle de acesso que leva em conta informações dinâmicas e suas combinações aumenta-se a segurança e, conseqüentemente, se ganha em produtividade em relação à propriedade de disponibilidade de serviços, dados e recursos computacionais.

O presente trabalho propõe o desenvolvimento de formas lipossomais contendo levana (Lev-LIPO) com potencial ação antitumoral e imunomoduladora na terapia contra o câncer. Lev-LIPO foram obtidos pelo método de formação do filme lipídico. Análises físico-químicas foram realizadas imediatamente após a preparação dos lipossomas. Adicionalmente, testes de estabilidade acelerada e em longo prazo foram realizados. O tamanho de partícula e a carga de superfície foram determinados utilizando contador de partículas zetasizer®. A quantidade de levana incorporada nos Lev-LIPO foi determinada após solubilização dos mesmos com metanol (1:1), extração e hidrólise ácida da levana para doseamento da frutose constituinte, por espectrocolorimetria a 530 nm, ou doseamento da levana, diretamente, por CLAE, usando detector de índice de refração, para análise comparativa entre os dois métodos. A eficiência de encapsulação foi determinada após ultrafiltração-centrifugação. O perfil de liberação in vitro da levana a partir de Lev-LIPO foi determinado utilizando o método de diálise. Lev-LIPO tendo concentrações de levana até 1,8 mg/mL apresentaram um aspecto opalescente, leitoso, com brilho azulado, mantendo as características iniciais por mais de 180 dias quando armazenadas a 4°C ± 1°C. Lev-LIPO apresentou um tamanho de partícula igual a 145 ± 75,01 nm. O potencial zeta dos Lev-LIPO tende a diminuir a medida que se aumenta a concentração da levana na formulação, variando de 21,33 (1 mg/mL) até 2,51 mV (20 mg/mL). A eficiência de encapsulação foi de 87,59 ± 1,21% por espectrocolorimetria e de 88,67 ± 1,69% por CLAE. A cinética de liberação da levana apresentou um efeito de rajada de 10,59 ± 3,49% na primeira hora, seguida por uma liberação lenta e controlada do produto bioativo, com velocidade constante de 0,27 mg/h na segunda fase (8 72 horas). A levana encapsulada se difundiu no meio após 96 horas (98,70 ± 0,85%). O desenvolvimento de lipossomas estáveis contendo levana é um passo importante no desenvolvimento de uma nova forma farmacêutica para a terapia do câncer

This research had the general objective to develop a proposal for supervising action for the orientation and follow-up of the formation processes in context, developed by pedagogical coordinators with the teachers, in the thematic evaluation of learning. For the elaboration of the proposal, we look for theoretical references that subsidize the understanding of the role of the school supervisor and the pedagogical coordinator in the daily school life; the analysis of the concepts built on formation processes in context in the educational units; and the conceptions that underlie the evaluation process of classroom learning. The proposal consisted in organizing mentoring meetings, inspired by the tutorial actions developed by Fundação Itaú Social, together with the pedagogical coordinator, to carry out activities such as diagnosis of the school context, analysis of pedagogical documentation, monitoring and structuring of their work routine. The research of qualitative approach involved the obtaining of descriptive data, through questionnaires and a collective interview for submission of the proposal of supervisory action to pedagogical coordinators and school supervisors, linked to the Municipal Department of Education of São Paulo, aiming to gather data about the usefulness, viability and modifications relevant to their implementation. The result of the research was the presentation of a proposal for a supervisory action that emphasizes a proactive role of the school supervisor in daily observation, reality analysis, discussion of referrals and formation strategies with the pedagogical coordinator, indicating the need to build links and partnerships that allow the follow-up, orientation and evaluation of the educational unit, as well as promote the process of awareness and involvement, both of pedagogical coordinators and the school supervisor, in a qualified work of evaluating learning and strengthening of formation spaces in context

The work presented in this thesis discusses various formal language formalisms that extend classical formalisms like regular expressions and context-free grammars with additional abilities, most relating to order. This is done while focusing on the impact these extensions have on the efficiency of parsing the languages generated. That is, rather than taking a step up on the Chomsky hierarchy to the context-sensitive languages, which makes parsing very difficult, a smaller step is taken, adding some mechanisms which permit interesting spatial (in)dependencies to be modeled. The most immediate example is shuffle formalisms, where existing language formalisms are extended by introducing operators which generate arbitrary interleavings of argument languages. For example, introducing a shuffle operator to the regular expressions does not make it possible to recognize context-free languages like anbn, but it does capture some non-context-free languages like the language of all strings containing the same number of as, bs and cs. The impact these additions have on parsing has many facets. Other than shuffle operators we also consider formalisms enforcing repeating substrings, formalisms moving substrings around, and formalisms that restrict which substrings may be concatenated. The formalisms studied here all have a number of properties in common. They are closely related to existing regular and context-free formalisms. They operate in a step-wise fashion, deriving strings by sequences of rule applications of individually limited power. Each step generates a constant number of symbols and does not modify parts that have already been generated. That is, strings are built in an additive fashion that does not explode in size (in contrast to e.g. Lindenmayer systems). All languages here will have a semi-linear Parikh image. They feature some interesting characteristic involving order or other spatial constraints. In the example of the shuffle multiple derivations are in a sense interspersed in a way that each is unaware of. All of the formalisms are intended to be limited enough to make an efficient parsing algorithm at least for some cases a reasonable goal. This thesis will give intuitive explanations of a number of formalisms fulfilling these requirements, and will sketch some results relating to the parsing problem for them. This should all be viewed as preparation for the more complete results and explanations featured in the papers given in the appendices.
Denna avhandling diskuterar utökningar av klassiska formalismer inom formella språk, till exempel reguljära uttryck och kontextfria grammatiker. Utökningarna handlar på ett eller annat sätt omordning, och ett särskilt fokus ligger på att göra utökningarna på ett sätt som dels har intressanta spatiala/ordningsrelaterade effekter och som dels bevarar den effektiva parsningen som är möjlig för de ursprungliga klassiska formalismerna. Detta står i kontrast till att ta det större steget upp i Chomsky-hierarkin till de kontextkänsliga språken, vilket medför ett svårt parsningsproblem. Ett omedelbart exempel på en sådan utökning är s.k. shuffle-formalismer. Dessa utökar existerande formalismer genom att introducera operatorer som godtyckligt sammanflätar strängar från argumentspråk. Om shuffle-operator introduceras till de reguljära uttrycken ger det inte förmågan att känna igen t.ex. det kontextfria språket anbn, men det fångar istället vissa språk som inte är kontextfria, till exempel språket som består av alla strängar som innehåller lika många a:n, b:n och c:n. Sättet på vilket dessa utökningar påverkar parsningsproblemet är mångfacetterat. Utöver dessa shuffle-operatorer tas också formalismer där delsträngar kan upprepas, formalismer där delsträngar flyttas runt, och formalismer som begränsar hur delsträngar får konkateneras upp. Formalismerna som tas upp här har dock vissa egenskaper gemensamma. De är nära besläktade med de klassiska reguljära och kontextfria formalismerna. De arbetar stegvis, och konstruerar strängar genom successiva applikationer av individuellt enkla regler. Varje steg genererar ett konstant antal symboler och modifierar inte det som redan genererats. Det vill säga, strängar byggs additivt och längden på dem kan inte explodera (i kontrast till t.ex. Lindenmayer-system). Alla språk som tas upp kommer att ha en semi-linjär Parikh-avbildning. De har någon instressant spatial/ordningsrelaterad egenskap. Exempelvis sättet på vilket shuffle-operatorer sammanflätar annars oberoende deriveringar. Alla formalismerna är tänkta att vara begränsade nog att det är resonabelt att ha effektiv parsning som mål. Denna avhandling kommer att ge intuitiva förklaring av ett antal formalismer som uppfyller ovanstående krav, och kommer att skissa en blandning av resultat relaterade till parsningsproblemet för dem. Detta bör ses som förberedande inför läsning av de mer djupgående och komplexa resultaten och förklaringarna i de artiklar som finns inkluderade som appendix.

In this thesis, the author presents a query language for an RDF (Resource Description Framework) database and discusses its applications in the context of the HELM project (the Hypertextual Electronic Library of Mathematics). This language aims at meeting the main requirements coming from the RDF community. in particular it includes: a human readable textual syntax and a machine-processable XML (Extensible Markup Language) syntax both for queries and for query results, a rigorously exposed formal semantics, a graph-oriented RDF data access model capable of exploring an entire RDF graph (including both RDF Models and RDF Schemata), a full set of Boolean operators to compose the query constraints, fully customizable and highly structured query results having a 4-dimensional geometry, some constructions taken from ordinary programming languages that simplify the formulation of complex queries. The HELM project aims at integrating the modern tools for the automation of formal reasoning with the most recent electronic publishing technologies, in order create and maintain a hypertextual, distributed virtual library of formal mathematical knowledge. In the spirit of the Semantic Web, the documents of this library include RDF metadata describing their structure and content in a machine-understandable form. Using the author's query engine, HELM exploits this information to implement some functionalities allowing the interactive and automatic retrieval of documents on the basis of content-aware requests that take into account the mathematical nature of these documents.

With the current rapid computerisation and automation of systems, which were previously controlled manually, a growing demand for measures to ensure correctness of systems is arising. This can be achieved with formal verification. With formal verification, systems can be proved to satisfy, or not satisfy, a set of given properties. In cases where a system does not satisfy the given properties, a counterexample is presented, but counterexamples are, more often than not, hard to interpret manually. Thus, automatic procedures for explaining counterexamples are needed but unfortunately few. This thesis will focus on the explanation of counterexamples from failed formal verifications of systems. An algorithm for doing such is presented in this thesis. This algorithm is shown to give desired explanations for some cases whilst just the bare minimum for the majority of cases. A number of procedures to obtain the latter are already known. However, a small problem, left unsolved, can bring desired explanations to the majority of cases if solved. The presented algorithm is, unfortunately, not free from flaws nor errors, but it is still unclear how severe these are.

Annotation:

Role-based modeling has been investigated for over 35 years as a promising paradigm to model complex, dynamic systems. Although current software systems are characterized by increasing complexity and context-dependence, all this research had almost no influence on current software development practice, still being discussed in recent literature. One reason for this is the lack of a coherent, comprehensive, readily applicable notion of roles. Researchers focused either on relational roles or context-dependent roles rather then combining both natures. Currently, there is no role-based modeling language sufficiently incorporating both the relational and context-dependent nature of roles together with the various proposed constraints. Hence, this paper formalizes a full-fledged role-based modeling language supporting both natures. To show its sufficiency and adequacy, a real world example is employed.

Branded content as an advertising tactic is a growing phenomenon that is not widely researched and is generally ambiguous in nature. This study uses qualitative methods to explain how branded content is defined, how it functions, and how it can influence a brand. Case studies of IKEA and Chevrolet were compared alongside four interviews with branded content professionals. the data collected suggests that branded content in structure and substance is varied, however it comprises engagement, the brand, and financial transaction. the data collected also suggested that brands take a variety of stances when controlling content to support their brand, and that branded content generally supports the intangible aspects of a brand, as opposed to product features.

The adsorption behaviour of trace metals in soil may provide us with a way to more accurately predict and assess the toxicity of metals in the environment. This thesis reports efforts to apply surface complexation modeling to agricultural and forest soil and to relate model parameters to common soil properties. This study considered Ca, Cd, Cu, Pb and Zn but the methods here could be applied to other metals. In Chapter 2, the surface charge and adsorption behaviour of a set of Ap horizons was characterised using back-titration and batch adsorption techniques. With the objective of simplifying the application of the NICCA model to surface charge and cation adsorption in whole soils the parameters of the NICCA model were related to soil properties (Chapter 3). Four of the six surface charge parameters could be predicted from soil properties and this enabled me to reasonably predict the surface charge of a second group of soils from soil properties. These results suggest that it is possible to make reasonable predictions about the surface charge and adsorption behaviour of a given type of soil using some easily measurable soil properties and a set of generic NICCA adsorption parameters for that soil type. In Chapter 4 this idea is applied to the determination of lime requirement for the agricultural soils.

O benzoilmetronidazol (BZM) é um fármaco lipossolúvel e de escolha para o tratamento da tricomoníase e da amebíase sintomática. Também é considerado tratamento alternativo para giardíase, infecções bacterianas aeróbicas e anaeróbicas graves e vaginites causadas por Gardnerella vaginalis. Nesse trabalho, sistemas nanoemulsionados contendo BZM foram obtidos pela técnica de emulsificação espontânea, visando à administração tópica vaginal. Em uma primeira etapa, duas diferentes formulações foram preparadas, diferindo quanto ao sistema surfactante empregado, Solutol HS 15 ou Solutol HS 15 + Tween 80, as quais foram denominadas de SOL e SOL+TW, respectivamente. A solubilidade do BZM em vários óleos foi previamente testada, e os resultados obtidos após análise por CLAE levaram à seleção do óleo de oliva como componente oleoso das formulações. A técnica de emulsificação espontânea conduziu à obtenção de nanoemulsões com diâmetro médio de gotícula que variou de 90 a 740nm, o qual foi confirmado após visualização das formulações por microscopia eletrônica de transmissão. As nanoemulsões apresentaram potencial zeta negativo, decorrente da presença de lecitina nas formulações, mas os valores obtidos foram relativamente baixos, provavelmente devido à presença do surfactante não iônico na superfície das gotículas. Visando a obtenção de uma forma farmacêutica para uso tópico, hidrogéis contendo as nanoemulsões foram preparados pela adição de hipromelose às dispersões coloidais. Os resultados de viscosidade e pH dos hidrogéis foram similares para as formulações SOL e SOL+TW. Na segunda etapa do trabalho, uma metodologia analítica de CLAE foi desenvolvida e validada para a quantificação do BZM nas nanoemulsões. O método demonstrou ser linear, preciso, exato e específico para a determinação do BZM nas formulações. O teor de BZM foi de 0,943mg/mL e 0,969 mg/mL para as formulações SOL e SOL+TW, respectivamente. Em uma última etapa, foi realizado o estudo de liberação in vitro do BZM a partir dos hidrogéis contendo as nanoemulsões e do medicamento comercial na forma de emulsão, utilizando células de difusão tipo Franz e membrana sintética de acetato de celulose. O fluxo (J, ?g.cm-2.min-1) e coeficiente de permeabilidade (Kp, cm-2.min-1) variaram na seguinte ordem: SOL+TW < GENÉRICO < SOL. O conjunto dos resultados obtidos demonstra a influência dos componentes das formulações sobre as propriedades físico-químicas das nanoemulsões, bem como no perfil de liberação in vitro do BZM.

The evolution of smart devices and software technologies has expanded the domain of computing from workplaces to other areas of our everyday life. This trend has been rapidly advancing towards ubiquitous computing environments, where smart devices play an important role in acting intelligently on behalf of the users. One of the sub fields of the ubiquitous computing is context-aware systems. In context-aware systems research, ontology and agent-based technology have emerged as a new paradigm for conceptualizing, designing, and implementing sophisticated software systems. These systems exhibit complex adaptive behaviors, run in highly decentralized environment and can naturally be implemented as agent-based systems. Usually context-aware systems run on tiny resource-bounded devices including smart phones and sensor nodes and hence face various challenges. The lack of formal frameworks in existing research presents a clear challenge to model and verify such systems. This thesis addresses some of these issues by developing formal logical frameworks for modelling and verifying rule-based context-aware multi-agent systems. Two logical frameworks LOCRS and LDROCS have been developed by extending CTL* with belief and communication modalities, which allow us to describe a set of rule-based context-aware reasoning agents with bound on time, memory and communication. The key idea underlying the logical approach of context-aware systems is to define a formal logic that axiomatizes the set of transition systems, and it is then used to state various qualitative and quantitative properties of the systems. The set of rules which are used to model a desired system is derived from OWL 2 RL ontologies. While LOCRS is based on monotonic reasoning where beliefs of an agent cannot be revised based on some contradictory evidence, the LDROCS logic handles inconsistent context information using non-monotonic reasoning. The modelling and verification of a healthcare case study is illustrated using Protégé IDE and Maude LTL model checker.

Esta tesis doctoral pretende aportar nuevos datos sobre los efectos del enfoque AICLE (Aprendizaje Integrado de Contenido y Lengua Extranjera) en las habilidades productivas y receptivas de los alumnos de una escuela privada de Barcelona (Catalunya). Se trata de una comunidad bilingüe en la que las lenguas oficiales son el catalán y el español y en la que el inglés representa la tercera lengua del curriculum. Con este objetivo, se analizan longitudinalmente 100 alumnos bilingües catalán / español de edades comprendidas entre 12 y 15 a lo largo de dos años académicos en dos contextos de exposición diferentes: EFL (inglés sólo como asignatura de lengua extranjera, n=50, grupo de control) y AICLE (inglés como medio de instrucción cuando estudian ciencias naturales, n=50, grupo experimental). Se extraen datos a partir de las habilidades productivas y receptivas y se analizan de forma cuantitativa y cualitativa utilizando un diseño posttest al final de cada curso académico. Los resultados demuestran la efectividad del enfoque AICLE aunque no de forma generalizada en todas las habilidades. A diferencia de investigaciones anteriores, es importante destacar la mejora de la corrección dentro de la producción escrita y de las habilidades léxico-gramaticales. Finalmente, los resultados tienden a confirmar que el factor edad es relevante y que obtienen mejores resultados los sujetos mayores.
The present study seeks to contribute new evidence on the effects of the CLIL approach (Content and Language Integrated Learning) on the learners’ productive and receptive skills in a private school in Barcelona (Catalonia). This is a bilingual community in which both Catalan and Spanish are official languages and where English represents the third language included in the currículum. For that purpose, 100 bilingual Catalan / Spanish students aged 12 to 15 are analysed longitudinally over two academic years in two different types of exposure contexts: EFL (English only as a foreign language school subject, n=50, control group) and CLIL (English as medium of instruction when learning Science, n=50, experimental group). Data are elicited both for productive and comprehension skills and are analysed quantitatively and qualitatively using a posttest design at the end of each academic year. The results show the effectiveness of the CLIL approach, however not in all skills. In contrast with findings published in previous studies, the subjects’ writing and particularly so accuracy, significatively progressed and so did lexico-grammatical abilities.Results also tend to confirm that age had an impact and thus the older, the better.

This work aims the construction of sociological portraits that restore processes of socialization, as a method for the analysis of the interactions the teacher performs and how they potentiate his/her dispositions from the generating principle of habitus in order to respond to the daily challenges in the classroom and the school, changing the teacher identity in the contexts of workin this process. The hypotheses were based in presupposition that admit the reconfiguration of the teacher identity from the interactions in the contexts of work which lead him/her to accept actions and attitudes that come from dispositions dependent of thehabitus. This work aims to investigate these elements by means of the construction of sociological portraits of three teachers from Primary School, registering their individual trajectories; semi-structured interviews were used, planned according to a conceptual grid that allowed the elaboration of guidelines constituted by six categories: family, school, work, sociability, leisure/culture and body: each teacher answered 160 questions in 37 hours of interview. The data collection was accomplished in the second semester of 2012, after a model interview to test the instrument built for the collection.The teachers also answered a social-economic questionnaire that allowed the characterization of the research subjects.The theoretical support of the analysis is based on the logic that the subject s social construction happens through the generating principle of habitus (BOURDIEU s) that configures the dispositions constructed in the process (LAHIRE s) through the life and work trajectory and that respond by the interveners linked to the professional identities (DUBAR s). The bibliographical search demonstrates that the studies related to the theme find the importance of the socialization processes for the constitution of identities, take the educational politics as mechanism to explain the identity crisis and discuss the formation and the practices, in order to indicate the problems faced by the teachers in the school routine. However, studies in the sociological perspectives were not privileged, focusing the identity and the subject to decipher the structures of this matrix of perceptions and analyze how it interferes in the constitution of dispositions. The results show that the dispositions constructed by the teachers are deeply related to the structures of the habitus and that, although they have specificities linked to the singular interpretation that each of them express in their daily actions in the different contexts of professional insertion, they elapse from this generating principle. On the other hand, those dispositions, when in a showing-hiding game to answer the daily demands, show a tendency to maintain the regularities oriented by the habitus and promote an identity reconfiguration with disruptions and changes based on weak and temporary mobilizations. The study still reveals that the fact that the analysis privilege the teachers context of work implicates the use of the term identity forms , once that analysis is limited to a historical period and to a certain type of social context, constituted by individual and collective actionsthat respond for social constructions shared with everybody who have had similar trajectories, mainly in the professional field
Esta pesquisa tem por objetivo a construção de retratos sociológicos que recuperam processos de socialização, como método para a análise das interações que o professor realiza e de que modo elas potencializam suas disposições a partir do principio gerador do habitus para responder aos desafios do cotidiano na sala de aula e na escola, transformando nesse processo sua identidade docente nos contextos de trabalho. As hipóteses norteadoras foram pautadas em pressupostos que admitem a reconfiguração da identidade docente a partir das interações nos contextos de trabalho que o levam a assumir ações e atitudes oriundas de disposições dependentes do habitus. A pesquisa propôs-se a investigar esses elementos por meio da construção de retratos sociológicos de três professoras da educação básica para registrar suas trajetórias individuais; foram utilizadas entrevistas semi-estruturadas, planejadas de acordo com uma grade conceitual que permitiu a elaboração de um roteiro constituído por seis categorias: família, escola, trabalho, sociabilidade, lazer/cultura e corpo; cada professora respondeu a 160 questões em 37 horas de entrevistas. A coleta de dados foi realizada no segundo semestre do ano de 2012, após uma entrevista modelo para testar o instrumento de coleta construído. As professoras responderam ainda, a um questionário sócio-econômico que permitiu a caracterização dos sujeitos de pesquisa. A sustentação teórica da análise se pauta na lógica de que a construção social do sujeito se dá a partir do princípio gerador do habitus (BOURDIEU) que configura as disposições construídas em processo (LAHIRE) ao longo da trajetória de vida e trabalho e que respondem pelos intervenientes ligados às identidades profissionais (DUBAR). O levantamento bibliográfico realizado demonstra que os estudos realizados sobre o tema constatam a importância dos processos de socialização para constituição das identidades, toma as políticas educacionais como mecanismo para explicar a crise identitária e discute a formação e as práticas, para indicar os problemas vividos pelos professores no cotidiano da escola. Porém, não privilegiaram estudos na perspectiva sociológica, com foco na identidade e no sujeito para decifrar as estruturas dessa matriz de percepções e analisar como ela interfere na constituição das disposições. Os resultados apontam que as disposições construídas pelas professoras estão intimamente relacionadas com as estruturas constituintes do habituse que, embora possuam especificidades ligadas à interpretação singular que cada uma delas expressa nas suas ações cotidianas nos diferentes contextos de inserção profissional, elas decorrem desse princípio gerador. Por outro lado, essas disposições, acionadas num jogo de mostrar-ocultar para responder às demandas cotidianas, mostram uma tendência a manter as regularidades orientadas pelo habitus e promovem uma reconfiguração identitária com rupturas e mudanças pautadas em fracas e provisórias mobilizações. O estudo revela ainda que, o fato de a análise privilegiar o contexto de trabalho das professoras, implica o uso do termo formas identitárias , uma vez que a análise se limita a uma época histórica e a um tipo de contexto social, constituída por ações individuais e coletivas que respondem por construções sociais compartilhadas com todos que têm trajetórias homólogas, principalmente no campo profissional

A Síndrome da Imunodeficiência Adquirida (AIDS) é uma doença de amplo espectro de manifestações, sendo razão de preocupação para qualquer autoridade sanitária. A terapêutica da AIDS é complexa sendo utilizados vários medicamentos, diversas vezes ao dia. Deste modo, objetivou-se o desenvolvimento de formas farmacêuticas sólidas como comprimidos tamponados mastigáveis (CTM), comprimidos com revestimento gastro-resistentes (CRGR) e pellets (PEL) para a veiculação de didanosina (ddl). Seis especialidades farmacêuticas na forma de CTM foram estudadas quanto ao perfil de dissolução, pH do meio e capacidade neutralizante ácida (CNA). Formulações teste de CTM foram propostas visando obter CNAs e perfis de dissolução adequados. Também foram testadas formulações de comprimidos e de pellets para posterior revestimento com filme gastro-resistente derivado do ácido metacrílico. Os ensaios de dissolução das amostras de CTM revelaram diferenças nas características de liberação do fármaco. Também foram observadas diferenças relacionadas a CNA. As formulações de CTM propostas apresentaram, na maioria dos casos, adequados perfis de dissolução e CNA. As formulações CRGR que receberam revestimento gastro-resistente apresentaram perfis de dissolução de ddl adequados, entretanto os comprimidos testados intumesceram em meio ácido, indicando descontinuidade do filme polimérico sobre os comprimidos. Testes para a produção de pellets veiculando ddl mostraram-se adequados quanto à morfologia e dissolução do fármaco, o mesmo sendo observado após o revestimento com filme gastro-resistente.
The Acquired Immune Deficiency Syndrome (AIDS) is a disease that manifests itself in a myriad of ways. Because of this, the condition has been subject of concern to all sanitary authorities. The treatment of AIDS is complex and many types of medicine are used, many times a day. The objective of the present study was to develop solid pharmaceutical dosage forms such as buffered chewable tablets (CTM), gastro-resistant coating tablets (CRGR) and pellets (PEL) for the loading of didanosine (ddl). Six pharmaceutical specialties in the form of CTM were studied so as to identify the profile of the dissolution, the pH of the environment, and the neutralizing acid capacity (CNA). The use of CTM tests formulations was proposed with the objective of obtaining adequate CNA and dissolution profiles. Different compositions of tablets and pellets were tested for a later addition of gastro-resistant film derived from the methacrylic acid. The experiments on the dissolution of the sample of CTM showed differences in the characteristic of the release of the substance. Differences related to the CNA were also observed. The formulations of the CTM proposed showed to have, in the most number of the cases, both adequate dissolution behavior and CNA. The formulations of the CRGR that had received the gastro-resistant coating showed adequate profile of ddl dissolution; the tested tablets, however, swelled in the acid environment, therefore indicating a lack of continuity of the polymeric film over the tablets. The tests for the production of pellets showed adequate results as to its morphology and dissolution of ddl. The same was observed after coating the pellets with gastro-resistant film.

O objetivo deste trabalho é analisar e comparar as peças Death of a Salesman [Morte dum caixeiro viajante] (1949), do dramaturgo americano Arthur Miller (1915-2005), e Rasga Coração (1974), do dramaturgo brasileiro Oduvaldo Vianna Filho (Vianinha) (1936-1974), especialmente em relação aos elementos épicos presentes nelas. Ambas as obras possuem uma estrutura formal que apresenta passado e presente simultaneamente no palco. Uma vez que uma peça dramática pressupõe sempre o tempo presente exposto cenicamente, o fato de o passado ser parte estrutural de Death of a Salesman e Rasga Coração já o transforma num primeiro importante traço épico das duas obras. A partir daí, vários outros elementos épicos serão apontados e examinados durante o trabalho sendo que estes elementos são importantes na representação dos conflitos sócio-históricos presentes nos Estados Unidos dos anos 40 e no Brasil nas primeiras sete dé-cadas do século XX. Outro aspecto que as duas peças apresentam em comum é o fato de analisarem um conflito geracional entre pai e filho(s), que representa, ao mesmo tempo, o conflito entre forças sociais e históricas maiores. Estudar quais são estas forças sociais representadas é também objetivo da pesquisa. Isto fará com que semelhanças e diferen-ças entre as obras e seus contextos apareçam e sejam discutidas.
The objective of this research is to analyze and compare the plays Death of a Salesman (1949), by the American playwright Arthur Miller (1915-2005), and Rasga Coração, by the Brazilian playwright Oduvaldo Vianna Filho (Vianinha) (1936-1974), especially concerning their use of epic elements. Both plays have a formal structure that presents past and present simultaneously on stage. Since a dramatic work always presupposes the scenic exposure of the present as a central characteristic, the fact that the past is part of the structure of Death of a Salesman and Rasga Coração transforms it into the most important epic element in both plays. Other epic elements of importance for the repre-sentation of social and historical conflicts of the United States in the forties and of Bra-zil in the first seven decades of the XX century will be examined as well. Another char-acteristic shared by these two plays is the fact that they discuss the generation conflict between father and son(s) in a way that combines the representation of private family affairs to the one of bigger social and historical forces. To study the nature of these so-cial forces represented in the two plays is another objective of this research, which will discuss and point out similarities and differences between them and their respective so-cial contexts.

In order to limit the effects of anthropogenic climate change the world is moving away from the use of fossil fuels as a primary energy source. Bioenergy is expected to form a substantial contribution to this transitional strategy. In order to increase bioenergy production, underutilized forest harvest residues are being targeted as a fuel source. Even with favorable policies in place to encourage their use, the processing and collection of these previously disregarded resources is often prohibitively expensive. Quality factors such as material moisture content also impact the viability of harvest residues for fuel purposes. As a result, careful operational planning is of great importance to sourcing high quality, economically feasible biomass. To gain a better understanding of the forest biomass supply chain, a simulation model was developed for a case study located in coastal British Columbia, Canada. A seasonal moisture content trend was identified and incorporated to help develop a strategy for sourcing high quality materials. It was found for BC’s coastal temperate rainforest environment that by delaying biomass collection until the second summer after timber harvest an average delivered moisture content of 28% can be achieved rather than 38% is operations proceed in the first summer. This reduction in delivered moisture content also led to a decrease in delivered cost from $72.08 to $67.95 per oven dried tonne. Trucking and equipment configurations were also examined to identify least cost approaches to biomass collection under varying conditions. Comparing high productivity and low productivity equipment configurations showed a $26.08/ODT cost increase when switching to less productive equipment. By employing an electric centralized grinder transporting unprocessed harvest residues, costs were shown to decrease for all cutblock groups with a cycle time of less than four and a half hours. Least cost fleet size was found to be largely dependent on the average cycle time to the biomass source. And the volume of available biomass at a given cutblock was found to have an impact on delivered costs with a 20% increase in biomass volume resulting in a cost decrease of greater than $2/ODT.

Resumo: Os modelos probabilísticos de uma linguagem (MPL) são modelos matemáticos onde é definida uma função de probabilidade que calcula a probabilidade de ocorrência de uma cadeia em uma linguagem. Os parâmetros de um MPL, que são as probabilidades de uma cadeia, são aprendidos a partir de uma base de dados (amostras de cadeias) pertencentes à linguagem. Uma vez obtidas as probabilidades, ou seja, um modelo da linguagem, existe uma medida para comparar quanto o modelo obtido representa a linguagem em estudo. Esta medida é denominada perplexidade por palavra. O modelo de linguagem probabilístico que propomos estimar, está baseado nas gramáticas probabilísticas livres do contexto. O método clássico para estimar os parâmetros de um MPL (Inside-Outside) demanda uma grande quantidade de tempo, tornando-o inviável para aplicações complexas. A proposta desta dissertação consiste em abordar o problema de estimar os parâmetros de um MPL usando métodos de pontos interiores, obtendo bons resultados em termos de tempo de processamento, número de iterações até obter convergência e perplexidade por palavra
Abstract: In a probabilistic language model (PLM), a probability function is defined to calculate the probability of a particular string ocurring within a language. These probabilities are the PLM parameters and are learned from a corpus (string samples), being part of a language. When the probabilities are calculated, with a language model as a result, a comparison can be realized in order to evaluate the extent to which the model represents the language being studied. This way of evaluation is called perplexity per word. The PLM proposed in this work is based on the probabilistic context-free grammars as an alternative to the classic method inside-outside that can become quite time-consuming, being unviable for complex applications. This proposal is an approach to estimate the PLM parameters using interior point methods with good results being obtained in processing time, iterations number until convergence and perplexity per word

Aujourd'hui la recherche en biologie dispose d'une masse d'informations génomiques considérable qu'il faut comprendre fonctionnellement pour faire émerger de nouveaux concepts, qui formeront le berceau de nouvelles thérapies. Ces études mettent en jeu des mécanismes contrôlés à l'échelle moléculaire et nécessitent le traitement d'informations à haut-débit et de manière parallèle. Les travaux pluridisciplinaires présentés ont permis de mettre au point une technologie miniaturisée de culture de cellules en gouttes matricées sur supports solides, pour tester l'action des molécules sur le comportement de cellules. Après avoir mis au point un démonstrateur macroscopique validé par des transfections de molécules nucléiques, nous avons développé un protocole de fabrication de substrats miniaturisés capable de maintenir 100 nano-gouttes par cm² à l'aide d'un différentiel de tension de surface. Un robot de dispense de pico-gouttes a été intégré pour réaliser les gouttes de culture cellulaire de manière automatique. Le comportement des cellules au sein des gouttes est évalué par microscopie en fluorescence à haut-contenu après fixation. Chaque cellule de chaque goutte est caractérisée par des dizaines de paramètres de manière individuelle. Cette nouvelle approche analytique a été appliquée dans le cadre d'un projet multipartenaire de criblage de siRNA visant à étudier l'impact de gènes sur la chimiorésistance de glioblastomes. Par ailleurs nous avons montré l'utilisation de la spectrométrie de masse comme méthode de phénotypage multiparamétrique. Cette technologie de puce à cellules est particulièrement adaptée à l'étude à haut-débit des comportements fins de cultures cellulaires
Nowadays biology research is faced with a considerable amount of genomic data which has to be functionally characterised in order to bring new concepts, which will lead to new therapies. These studies approach molecular-based mechanisms, and need high-throughput and parallel data management. The multidisciplinary work presented here has allowed the development of a miniaturised technology of cell culture in liquid drops, matrixed on a plane solid substrate, to test the action of molecules or conditions on the cells behaviour. After the macroscopic demonstration of nucleic acid molecule transfection in living cells on such a device, we have developed a fabrication protocol for a miniaturised support, able to maintain 100 nano-drops per cm², based on differential surface tensions. A picoliter dispensing robot was integrated to make the cell culture drops automatically. The cells' behaviour in the drops is analysed by high-content fluorescence microscopy after fixation. Each cell of each drop is characterised by tenths of parameters individually. This new analytical approach, which has triggered the development of new bio-statistical tools, has been applied to a multipartner project of siRNA screening, aimed at studying the impact of genes on glioblastoma cells chemoresistance. We have also shown the use of mass spectrometry as a multiparametric phenotyping method. This cell-on-chip technology seems particularly well suited for the study of the precise behaviour of cells among a population at high-throughput. It will be the base of new lab-on-chip technologies

In this thesis, three methods are investigated to express context-free tree languages by regular tree grammars. The first method is a characterization. We show restrictions to context-free tree grammars such that, for each restricted context-free tree grammar, a regular tree grammar can be constructed that induces the same tree language. The other two methods are approximations. An arbitrary context-free tree language can be approximated by a regular tree grammar with a restricted pushdown storage. Furthermore, we approximate weighted context-free tree languages, induced by weighted linear nondeleting context-free tree grammars, by showing how to approximate optimal weights for weighted regular tree grammars.

A person who is communication about (the data subject) has to keep track of all of his revealed data in order to protect his right of informational self-determination. This is important when data is going to be processed in an automatic manner and, in particular, in case of automatic inquiries. A data subject should, therefore, be enabled to recognize useful decisions with respect to data disclosure, only by using data which is available to him.

For the scope of this thesis, we assume that a data subject is able to protect his communication contents and the corresponding communication context against a third party by using end-to-end encryption and Mix cascades. The objective is to develop a model for analyzing the linkability of communication contents by using Formal Concept Analysis. In contrast to previous work, only the knowledge of a data subject is used for this analysis instead of a global view on the entire communication contents and context.

As a first step, the relation between disclosed data is explored. It is shown how data can be grouped by types and data implications can be represented. As a second step, behavior, i. e. actions and reactions, of the data subject and his communication partners is included in this analysis in order to find critical data sets which can be used to identify the data subject.

Typical examples are used to verify this analysis, followed by a conclusion about pros and cons of this method for anonymity and linkability measurement. Results can be used, later on, in order to develop a similarity measure for human-computer interfaces.

Num mundo mais digital, é importante as empresas analisarem e anteciparem os seus consumidores, que são cada vez mais digitais e utilizadores de sites de redes sociais. Portanto, esta investigação pretende compreender o impacto do marketing de conteúdo digital na comunicação, perceções de conteúdo, perceção de congruência com a imagem de marca própria e intenções de compra dos consumidores, através do Instagram. Assim, as empresas poderão desenvolver estratégias de conteúdos digitais ponderadamente e ir ao encontro daquilo que os públicos-alvo pretendem. Este estudo questiona se as narrativas, o boca a boca eletrónico, as perceções dos conteúdos e a forma de os comunicar, no Instagram, influenciam a intenção de compra. A presente investigação segue uma abordagem dedutiva, de natureza exploratória e explanatória. Este estudo de métodos mistos usa uma amostra não probabilística por conveniência. Primeiramente, recolheram-se os dados através da realização de quatro entrevistas semiestruturadas; numa segunda fase, recolheram-se dados através de um inquérito online, cross-sectional, obtendo-se 400 respostas finais completas e válidas, com o software IBM SPSS Statistics. Os resultados indicam que, Storytelling, Eletronic word of mouth (E-WOM), Perceções do Conteúdo (perceção de valor funcional, perceção de valor hedónico) e perceção de congruência com a imagem de marca própria afetam positivamente a intenção de compra. A idade tem um efeito moderador na relação entre E-WOM e intenção de compra. Este tema é pertinente, pois o efeito destas variáveis tem de ser mais conhecido, principalmente num ano pandémico que aumentou o uso dos sites de redes sociais e de estratégias digitais.
In a more digital world, it is important for companies to analyze and anticipate their consumers, who are increasingly digital and users of social networking sites. Therefore, this investigation intends to understand the impact of digital content marketing on communication, on consumers' perceptions of content and purchase intentions, through the Instagram, enabling companies to develop digital content thoughtfully and meet what the target audiences want. This study questions if storytelling, electronic word of mouth, the perceptions of content, congruence with the brand image perception and the way of communicating on Instagram influence the purchase intention. The present investigation follows a deductive approach, of an exploratory and explanatory nature. This study of mixed methods uses a non-probabilistic sample for convenience. First, data was collected through the performance of four classifieds; in a second phase, data was collected through an online inquiry, transversal investigation, obtaining 400 complete and valid final answers, with statistical treatment and analysis using the IBM SPSS Statistics software. The main results indicate that Storytelling, Eletronic Word of Mouth (E-WOM), Content Perceptions (functional value perception, hedonic value perception) and congruence with the brand image perception positively affect the purchase intention. Age has a moderating effect on the relationship between E-WOM and purchase intention. This topic is relevant, as the effect of these communication variables used in the context of Instagram, needs to be better known, especially in a pandemic year that increased the use of social networking sites and appropriate digital strategies.
