Apesar do crescente interesse no conceito de engajamento da marca ainda existe discordância quanto aos seus conceitos fundamentais. Esta tese de doutorado explora a natureza da construção engajamento da marca do consumidor (EMC). No primeiro artigo, EMC é avaliada no âmbito da Teoria da Expectância para explicar e esclarecer como a antecipação de possíveis resultados de se envolver com uma marca, sendo tais resultados classificados como “primeiro nível” (resultante do esforço pessoal alocado para interagir com uma marca) e “segundo nível” (ou nível final, representando a consequência dos resultados de primeiro nível) e uma nova definição de EMC é formulada. Um arcabouço teórico abrangente é proposto para engajamento da marca, usando o Teoria Organizacional de Marketing para Expansão de Fronteiras (TOMEF) como referência para os pontos de contato entre o consumidor e a marca. A partir dos fundamentos teóricos das dimensões cognitivas, emocionais e comportamentais do EMC, quinze proposições teóricas são desenvolvidas para incorporar uma perspectiva multilateral às doutrinas teóricas do construto. No segundo artigo, quatro estudos são usados para desenvolver uma escala de engajamento da marca do consumidor. O Estudo 1 (n = 11) utiliza revisão da literatura e entrevistas em profundidade com os consumidores para gerar os itens da escala. No Estudo 2, oito especialistas avaliam 144 itens quanto a validade de face e validade de conteúdo. No Estudo 3 dados coletados com alunos de graduação (n = 172) é submetida à análise fatorial exploratória (AFE) e confirmatória (AFC) para redução adicional de itens. Trezentos e oitenta e nove respostas de um painel de consumidores são usados no Estudo 4 para avaliar o ajuste do modelo, usando a análise fatorial confirmatória (AFC) e Modelagem por Equações Estruturais (MEE). A escala proposta possui excelentes níveis de validade e confiabilidade. Finalmente, no terceiro papel, uma escala de engajamento do consumidor de Vivek et al. (2014) é replicada (n = 598) junto à consumidores em uma feira automotiva, para estender o debate sobre formas de medição do constructo usando a perspectiva da Teoria de Resposta ao Item (TRI). Embora o modelo desenvolvido com base na teoria clássica de teste (TCT) usando AFC, um modelo de resposta gradual (MRG) identifica cinco itens que têm baixos níveis de poder discriminante e com baixos níveis de informação. A abordagem usando TRI indica um possível caminho para melhorias metodológicas futuras para as escalas desenvolvidas na área de marketing em geral, e para a escala engajamento do consumidor, em particular.

A aprendizagem de um instrumento musical articula diferentes perspetivas tendo em conta convenções, técnicas, alunos, músicos, professores e escolas. A forma como a música é vista no contexto cultural e social, ainda representa um conjunto de múltiplas intersecções ancoradas a uma música ‘monocultural’. Nem as políticas nem as formações têm acompanhado as mudanças, originando um confronto paradigmático entre as tendências da tradição clássica romântica e as contemporâneas. Com objetivos em compreender e refletir sobre as práticas pedagógicas dos professores, esta investigação teve em consideração os seguintes pontos: a formação inicial dos professores e a sua influência no seu campo de ação; as tendências profissionais; a relação entre mestre e aluno; a cultura cultivada perante a popular; e um ensino da música como atividade extraescolar. O presente estudo foi realizado no Gabinete Coordenador de Educação Artística / Divisão de Expressões Artísticas, no Município do Funchal, partindo dos princípios etnográficos assentes na realização de entrevistas e observações no contexto da sala de aula. Por ser um estudo de caso, este trabalho não pretende fazer generalizações embora emerja do campo de análise, dados aos quais poderão constituir elemento de reflexão em outros trabalhos dentro deste campo musical. As convenções em articulação com as novas práticas emergentes resultam, numa aprendizagem híbrida, assente numa diversidade cultural e musical, num contexto extraescolar.

A Análise de Sobrevivência tem como objetivo o estudo do tempo desde um instante inicial bem definido até ao acontecimento de determinado evento. Por exemplo, poderá ser o tempo de vida de um indivíduo desde o momento em que lhe é diagnosticada uma doença até a sua morte ou cura. Com a evolução da medicina, começou a se verificar a existência de indivíduos para os quais nunca se observava o acontecimento de interesse e designaram-se esses indivíduos por curados, imunes, ou não suscetíveis. Assim, da Análise de Sobrevivência clássica surgem os modelos de cura. Neste trabalho, aplicaram-se estes conceitos a uma base de dados referentes a 833 mulheres diagnosticadas com cancro da mama, entre 1998 e 2005. Verificou-se a existência de um risco de morte maior em mulheres na faixa etária dos 50 a 59 anos. Comprovou-se que o estadiamento tem um papel preponderante em relação ao prognóstico, sendo que, quanto mais avançado o estadio pior o prognóstico. Dos tratamentos a que os doentes foram submetidos, a realização de cirurgia é indicativa de um melhor prognóstico, assim como a realização de hormonoterapia e de radioterapia. No entanto, este último tratamento não se revelou estatisticamente significativo para o modelo de regressão de Cox. A realização de quimioterapia apenas reflete um melhor prognóstico nos primeiros dois anos, o que já não acontece a partir dai. Esta caraterística inesperada ficou-se a dever à esperança de vida que o tratamento oferece aos doentes no estadio IV e da associação entre a existência de gânglios metastizados e o agravamento do prognóstico, no caso do estadio II. O modelo de cura foi aplicado apenas ao grupo de mulheres no estadio IV, pois só neste caso se admitiu que o tempo de follow-up era suficiente, obtendo-se uma taxa de cura de 7;4%.

O principal objectivo desta dissertação é dar a conhecer as potencialidades da linguagem R pois ainda existem algumas reservas quanto à sua utilização. E nada melhor que a análise de sobrevivência, por ser um tema da estatística com grande impacto no mundo das doenças e novas curas, para mostrar como este programa apresenta grandes vantagens. Esta dissertação é então composta por quatro capítulos. No primeiro capítulo introduzimos alguns conceitos fundamentais da análise de sobrevivência, os quais servirão de suporte para o terceiro capítulo. Assim sendo, apresentamos um pouco da sua história, conceitos básicos, conceitos novos numa perspectiva de regressão diferente da que estamos habituados, tendo como objectivo a construção de modelos de regressão tendo sempre em conta métodos para averiguar se o modelo é o mais adequado ou não. No segundo capítulo apresentamos o R, o package R Commander (que já tem um interface mais amigável), o package survival (talvez o mais importante na análise de sobrevivência clássica), bem como outros packages que poderão ser úteis para quem quiser aprofundar o seu uso nesta área. O terceiro capítulo é o que aplica os conhecimentos dos dois anteriores e no qual pretendemos dar a conhecer algumas das muitas possibilidades de utilização deste software nesta área da Estatística. Este é dividido em três, ou seja, está dividido consoante as etapas que vamos precisando para trabalhar a nossa base de dados, começando pela análise descritiva, para conhecermos os dados que temos, depois a função de sobrevivência, por ser um conceito importante e por m, a construção de modelos de regressão, não paramétricos e paramétricos. Por último, apresentamos as nossas conclusões deste trabalho.

The theme of corporate social responsibility (CSR) provides discussion and analysis and relatively recent, particularly in the last twenty years, has grown into the world as well as in Brazil, the interest on the involvement of the business sector in social activities or projects facing combating poverty. However, a lack of socialization of successful experiences in the practice of CSR and clarity and consensus concepts generate deviations of understanding on the subject and the structuring of interventions. This research aimed to reveal how corporate social responsibility of the IMA Food was developed from Project Nursery Saci. The research took place under a qualitative approach of descriptive-explanatory, conducted through semi-structured interviews and non-participatory observation and interviewed 35 people in total. The interpretation and analysis of data occurred through a categorical content analysis, having as theoretical approach to socioeconomic CSR. The results showed that the major form of social responsibility of the Food IMA is based on a classical approach of CSR, focusing on philanthropy. The absence of a more systematic management of the project and reflect the fragility, instability and lack of commitment towards the community. The contributions generated by the project are substantial and important, but do not reach the development occasioned by the company. However, none of this invalidates the initiative of the organization's commitment to the community, however, requires a reassessment and restructuring of the proposal in a way that leverages the performance of the project and the company itself and it can more effectively contribute to society

Since the 1970s, the world observes the fragmentation, hybridity, plurality and miscegenation that are taking over the scenic arts. The contemporary poetry feels free of the classical rules; theater no longer obeys the requirements of the poetic "manuals"; the rigid boundaries between genres disappears; artists cease to represent to the public to talk with him. In the last decades of twentieth century and in the twenty-first century, emerges the laughable phenomenon of One-man Show in the brazilian scene, object of this research, as a result of this evolution of the performing arts. It is a form of theater that emerged in the brazilian context, snatching public attention in alternative spaces, theaters and, as it should be, also on the Internet, often confused with the Stand-up Comedy. It is necessary a research that delimitate and pursue to identify the essential characteristics of the brazilian One- Man Show, not only by the absence of theoretical references concerning this, but also to understand some aspects of the brazilian scene and the situation of laughter and comedy in it. In the first chapter, a discussion about comedy and laughter in classical antiquity is presented, using the writings of Plato and Aristotle as a starting point; in the second, some of the main classical theories of laughter are reviewed, attempting to identify the general characteristics that enable to understand the construction of the comedy; the third chapter generally dicusses about the moment of the brazilian theatrical scene in which emerges the One-man Show; and in the fourth chapter, there is an explanation about this phenomenon and a description of the practical exercise titled Experimento One-person Show: Damas

Chromobacterium violaceum is a free-living bacillus, Gram-negative commonly found in water and sand of tropical and subtropical regions. One of its main characteristic it's the ability to produce the purple pigment named violacein, that shows countless biological activities. In 2003, the genome of this organism was totally sequenced and revealed important informations about the physiology of this bacteria. However, few post-genomics studies had been accomplished. This work evaluated the protein profile of C. violaceum cultivated in LB medium at 28ºC that allowed the identification and characterization of proteins related to a possible secretion system that wasn't identified and characterized yet in C. violaceum, to the quorum sensing system, to regulatory process of transcription and translation, stress adaptation and biotechnological potential. Moreover, the response of the bacteria to UVC radiation was evaluated. The comparison of the protein profile, analyzed through 2-D electrophoresis, of the control group versus the treatment group allowed the identification of 52 proteins that arose after stress induction. The obtained results enable the elaboration of a stress response pathway in C. violaceum generated by the UVC light. This pathway, that seems to be a general stress response, involves the expression of proteins related to cellular division, purine and pirimidine metabolism, heat chock or chaperones, energy supply, regulation of biofilm formation, transport, regulation of lytic cycle of bacteriophages, besides proteins that show undefined function. Despite the response present similarities with the classic SOS response of E. coli, we still cannot assert that C. violaceum shows a SOS-like response, mainly due to the absence of characterization of a LexA-like protein in this organism

Worldwide, families Carangidae and Rachycentridae represent one of the groups most important commercial fish, used for food, and great potential for marine aquaculture. However, the genetic bases that can underpin the future cultivation of these species, cytogenetic between these aspects are very weak. The chromosomal patterns have provided basic data for the exploration of biotechnological processes aimed at handling chromosomal genetic improvement, such as induction of polyploidy, androgenesis and ginogenesis, as well as obtaining monosex stocks and interspecific hybridizations. This paper presents a comprehensive cytogenetic survey in 10 species, seven of the family Carangidae and the monotypic family Rachycentridae. Classical cytogenetic analysis and in situ mapping of multigene sequences were employed, and additionally for the genus Selene and morphotypes of Caranx lugubris, comparisons were made using geometric morphometrics. In general, conservative species exhibit a marked chromosome number (2n=48). Although present in large part, different karyotypic form, retain many characteristics typical of chromosomal Order Perciformes, the high number of elements monobrachyal, Ag-NORs/18S rDNA sites and heterochromatin simply reduced, preferably centromeric. The main mechanisms involved in karyotypic diversification are the pericentric inversions, with secondary action of centric fusions. In addition to physical mapping and chromosome detail for the species are presented and discussed patterns of intra-and interspecific diversity, cytotaxonomic markers. This data set provides a better understanding of these patterns caryoevolutyonary groups and conditions for the development of protocols based on Biotechnology for chromosomal manipulation Atlantic these species

The industrial production of ornamental rocks and the burning of coffee husk generate waste that is discarded into the environment. However, with the study of the incorporation of these residues in ceramic products, may be found an alternative to reducing environmental impacts and detrimental effects on human health caused by its indiscriminate disposal of waste in nature. Thus, this work aimed to study the addition of ashes of the coffee husk and granite residue in matrix of red ceramic. The raw materials were dry milled and sieved to mesh 100. To characterize the raw materials were carried out analyzes of X-ray diffraction (XRD), X-ray fluorescence (XRF), particle size analysis (PSA), differential thermal analysis (DTA) and thermogravimetric analysis (TG). Six formulations were prepared where the clay content was kept constant (70%wt) and ashes contents and granite residue varied from 10, 15, 20 and 30%. Dilatometrics analyzes were performed at four selected formulations, containing them: 100% clay (A100); 70% clay and 30% ashes (A70C30); 70% clay and 30% granite residue (A70G30); and 70% clay, 15% granite residue and 15% ashes (A70G15C15). The samples were prepared by uniaxial compaction with pressure of 25 MPa, and fired at temperatures of 800°C, 850ºC, 900ºC, 950ºC, 1000ºC and 1100°C. Assays were performed to determine the linear shrinkage of burning (LSB), water absorption (WA), apparent porosity (AP), density (D) and tensile bending. Also were performed analyzes of X-ray diffraction (XRD) and scanning electron microscopy (SEM) of the samples fired. The formulations incorporating granite residue and/or ashes reached the required limits of water absorption according to NBR 15270-1 and NBR 15310 and tensile bending according to classical literature (SANTOS, 1989) necessary for the production of tiles and ceramic block for masonry sealing

Deep bed filtration occurs in several industrial and environmental processes like water filtration and soil contamination. In petroleum industry, deep bed filtration occurs near to injection wells during water injection, causing injectivity reduction. It also takes place during well drilling, sand production control, produced water disposal in aquifers, etc. The particle capture in porous media can be caused by different physical mechanisms (size exclusion, electrical forces, bridging, gravity, etc). A statistical model for filtration in porous media is proposed and analytical solutions for suspended and retained particles are derived. The model, which incorporates particle retention probability, is compared with the classical deep bed filtration model allowing a physical interpretation of the filtration coefficients. Comparison of the obtained analytical solutions for the proposed model with the classical model solutions allows concluding that the larger the particle capture probability, the larger the discrepancy between the proposed and the classical models

In this work we analyze the skin bioimpedance statistical distribution. We focus on the study of two distinct samples: the statistics of impedance of several points in the skin of a single individual and the statistics over a population (many individuals) but in a single skin point. The impedance data was obtained from the literature (Pearson, 2007). Using the Shapiro-Wilk test and the assymmetry test we conclude that the impedance of a population is better described by an assymetric and non-normal distribution. On the other side, the data concerning the individual impedance seems to follow a normal distribution. We have performed a goodnes of fitting test and the better distribution to fit the data of a population is the log-normal distribution. It is interesting to note that our result for skin impedance is in simtony with body impedance from the literature of electrical engeneering. Our results have an impact over the statistical planning and modelling of skin impedance experiments. Special attention we should drive to the treatment of outliers in this kind of dataset. The results of this work are important in the general discussion of low impedance of points of acupuncture and also in the problem of skin biopotentials used in equipments like the Electrodermal Screen Tests.

In this dissertation, the theoretical principles governing the molecular modeling were applied for electronic characterization of oligopeptide α3 and its variants (5Q, 7Q)-α3, as well as in the quantum description of the interaction of the aminoglycoside hygromycin B and the 30S subunit of bacterial ribosome. In the first study, the linear and neutral dipeptides which make up the mentioned oligopeptides were modeled and then optimized for a structure of lower potential energy and appropriate dihedral angles. In this case, three subsequent geometric optimization processes, based on classical Newtonian theory, the semi-empirical and density functional theory (DFT), explore the energy landscape of each dipeptide during the search of ideal minimum energy structures. Finally, great conformers were described about its electrostatic potential, ionization energy (amino acids), and frontier molecular orbitals and hopping term. From the hopping terms described in this study, it was possible in subsequent studies to characterize the charge transport propertie of these peptides models. It envisioned a new biosensor technology capable of diagnosing amyloid diseases, related to an accumulation of misshapen proteins, based on the conductivity displayed by proteins of the patient. In a second step of this dissertation, a study carried out by quantum molecular modeling of the interaction energy of an antibiotic ribosomal aminoglicosídico on your receiver. It is known that the hygromycin B (hygB) is an aminoglycoside antibiotic that affects ribosomal translocation by direct interaction with the small subunit of the bacterial ribosome (30S), specifically with nucleotides in helix 44 of the 16S ribosomal RNA (16S rRNA). Due to strong electrostatic character of this connection, it was proposed an energetic investigation of the binding mechanism of this complex using different values of dielectric constants (ε = 0, 4, 10, 20 and 40), which have been widely used to study the electrostatic properties of biomolecules. For this, increasing radii centered on the hygB centroid were measured from the 30S-hygB crystal structure (1HNZ.pdb), and only the individual interaction energy of each enclosed nucleotide was determined for quantum calculations using molecular fractionation with conjugate caps (MFCC) strategy. It was noticed that the dielectric constants underestimated the energies of individual interactions, allowing the convergence state is achieved quickly. But only for ε = 40, the total binding energy of drug-receptor interaction is stabilized at r = 18A, which provided an appropriate binding pocket because it encompassed the main residues that interact more strongly with the hygB - C1403, C1404, G1405, A1493, G1494, U1495, U1498 and C1496. Thus, the dielectric constant ≈ 40 is ideal for the treatment of systems with many electrical charges. By comparing the individual binding energies of 16S rRNA nucleotides with the experimental tests that determine the minimum inhibitory concentration (MIC) of hygB, it is believed that those residues with high binding values generated bacterial resistance to the drug when mutated. With the same reasoning, since those with low interaction energy do not influence effectively the affinity of the hygB in its binding site, there is no loss of effectiveness if they were replaced.

This study evaluated the effect of indole-3-acetic acid (IAA) in the activation of goats preantral follicles (FOPA). Were used four pairs of ovaries of adult mixed breed goats. Each ovarian pair was divided into 23 fragments. One fragment was fixed for histology and other fragment was using to follicular isolation procedure. The remaining fragments were cultured in 1.0 ml of Minimum Essential Medium (MEM) or MEM supplemented with IAA at concentrations of 10, 40, 100, 500 or 1000 ng/mL. The in vitro culture was performed at 39°C in incubator with 5% CO2 for 1, 3 and 5 days. After in vitro culture was evaluated histological integrity and viability of FOPA. The addition of 100 ng/ml of IAA to MEM showed a significant increase in follicles transition in the third day of in vitro culture, characterizing follicular activation. Moreover, this concentration was obtained maintaining the histological integrity of PAF by the fifth day of in vitro culture. The viability test confirmed the results of histology. Thus, we conclude that IAA can promote the activation of goats FOPA
