Comme la consommation de médias numériques a explosé ces dernières années, faire des photos esthétiques, avec ou sans expertise artistique, est plus que jamais un sujet de recherche. Plusieurs axes peuvent être explorés: la haute définition, la luminance ou contraste étendue, les gamut couleur étendus. En plus de ces propriétés intrinsèques de l'image, des connaissances perceptuelles et/ou artistiques seraient de grande valeur pour tout utilisateur manipulant le contenu des images. Cette thèse propose d'aborder le thème de l'harmonie des couleurs. La littérature en lien avec ce sujet se retrouve à travers diverses disciplines : la science des couleurs, le traitement d'image, la psychologie… Ces expériences menées en science des couleurs privilégient la mesure de patchs combinant deux ou trois couleurs, rendant l'extrapolation à des images naturelles impossibles. D'autres approches ont défini des lois empiriques dictant l'arrangement des couleurs sur la roue des teintes. Le cadre applicatif de ces modèles géométriques manque de rigueur quant à leur utilisation. Malgré cela, des algorithmes en traitement d'image employant ces modèles ont vus le jour. Si les résultats semblent qualitativement agréables, ces algorithmes méritent une validation plus quantitative et objective, faisant intervenir une base de données appropriée. Dans cette thèse, deux approches sont mises en perspective: un travail expérimental et une partie algorithmique. Une expérience a été menée à l'aide d'un oculomètre avec une tâche dédiée à l'analyse de l'harmonie des couleurs, permettant de mesurer des effets dans le déploiement de l'attention visuelle. A partir de ces données, une vérité terrain a été extrapolée, permettant la validation des méthodes algorithmiques ensuite proposées. En premier, nous avons amélioré l'état de l'art sur l'harmonisation automatique des images au travers de diverses contributions et avons démontré de façon exhaustive le gain de notre approche. En deuxième contribution algorithmique, nous avons introduit une nouvelle sorte de métrique de qualité qui combine les concepts de masquage visuel et d'harmonie des couleurs. Ainsi, nous pouvons prédire quelles zones de l'image seront perçues harmonieuses, au vue de leur voisinage et donc des effets de masquages potentiels. Enfin, une dernière contribution, nous a amené à dériver deux outils d'édition incorporant les deux techniques précédentes, permettant de rendre accessible les concepts d'harmonie des couleurs à travers une formulation cachée et intuitive. / Since the consumption of digital media exploded in the last decade, making aesthetic pictures quickly - with or without artistic expertise - is more than ever a research topic. Different axis of investigations remain possible: high resolution, high dynamic range or wide color gamut. Additionally to these objective image properties, more perceptual and artistic insights could be of benefit to any user manipulating pictures. In such context, this thesis deals with the topic of Color Harmony. The literature related to this topic is limited, but involves many different scientific areas: color science, image processing and psychology and so on. The validity of collected data is questionable due to their limitation to two- or three-colors patches. The models fitted from these data remain non-exploitable on natural pictures. Other models depicting rules or areas on color wheel lack scientific guidelines for their utilization. Nonetheless, some algorithms employing color harmony theory and models as a core concept showed up in the literature, but suffered from being quantitatively tested and validated. In this thesis, two views are put in perspective in order to respond to the previous statements: an experimental and a computational approaches. The conducted experiment allowed observing some effects with an eye-tracking protocol, never applied before with a task on color harmony assessment. From the collected data of our experimental work, we designed a method to generate a ground truth, which would serve to the validation of the two proposed computational methods. First, we improved an existing architecture for automatic color harmonization and demonstrated exhaustively the benefit of our approach. As a second computational contribution, a novel quality metric is introduced that integrates the concepts of visual masking and color harmony. Thus, we may predict which areas would be perceived harmonious regarding its neighborhood and then the potential masking effects. As a last contribution, two editing tools made accessible the color harmony theory through a hidden formulation of it and a user-friendly and intuitive interface.

Análise da obra de Joaquim Reis a partir de registros fotograficos e fotomomtagens / Analisis of the work from Joaquim Reis, photographer and artist

O efeito país de origem é um dos assuntos mais abordados na literatura internacional de negó-cios, marketing e comportamento do consumidor. Diante da importância deste tema, esta pesquisa realizou, utilizando a ferramenta eletroencefalografia, um experimento geral que foi subdividido em três experimentos. No primeiro experimento, buscou-se verificar a influência que a origem de fabricação dos vinhos exercia sobre as atividades cerebrais dos consumidores brasileiros em geral em relação a vinho com a informação de ser do Brasil, da França e sem informação. No segundo experimento, 3(País de origem: Brasil, França e sem informação ) x 2(Gênro: Masculino e Feminino) buscou-se verificar a influência da origem de fabricação sobre as respostas cerebrais dos homens e das mulheres. No terceiro experimento, 3(País de origem: Brasil, França e sem informação ) x 2(Envolvimento: Alto e Baixo) buscou-se verificar esta influência para os consumidores de alto e baixo envolvimento. O vinho utilizado era o mesmo e de origem brasileira. A amostra foi constituída por estudantes da universidade de São Paulo. Como resultados, foram verificados, por meio da análise espectral de potência, que a informação do país de origem não gerou influências significativas para os consumidores em geral e nem para as mulheres nem nenhum dos grupos (experimental e de controle). Mas gerou influência significativas para os homens no grupo experimental. Também foram verificados resultados diferentes para os consumidores de alto e baixo envolvimento. Os consumidores de alto envolvimento prestaram mais atenção a informação do país de origem, contudo esta informação não impactou emocionalmente os consumidores. Já para os consumidores de baixo envolvimento verificou-se diferenças significativas entre o grupo experimental Brasil e França e o grupo de controle França e sem informação. Em termos teóricos, esta pesquisa apresenta uma grande contribuição para a literatura ao conciliar de forma inédita o efeito país de origem com a ferramenta da neurociência EEG. Em termos práticos sugere uma diferenciação das ações de marketing (propaganda, anúncios, campanhas, disponibilização no ponto de venda) sobre os grupos de consumidores / The country-of-origin effect is one of the most addressed issues in the international business literature, marketing and consumer behavior. Considering the importance of this theme, this research carried out, using the electroencephalography tool, a general experiment that was subdivided into three experiments. In the first experiment, it was sought to verify the influence that the origin of wine manufacturing exerted on the brain activities of Brazilian consumers in general in relation to wine with the information of being from Brazil, France and without information. In the second experiment, 3 (Country of origin: Brazil, France and without information) x 2 (Gênro: Male and Female) sought to verify the influence of manufacturing origin on the brain responses of men and women. In the third experiment, 3 (Country of origin: Brazil, France and without information) x 2 (Involvement: High and Low) sought to verify this influence for the consumers of high and low involvement. The wine used was the same and of Brazilian origin. The sample consisted of students from the University of São Paulo. As results, power spectral analysis verified that the information from the country of origin did not generate significant influences for consumers in general, neither for women nor for any of the groups (experimental and control). But it generated significant influence for men in the experimental group. Different results have also been found for high and low involvement consumers. High-involvement consumers paid more attention to home country information, but this information did not impact consumers emotionally. For the low-involvement consumers, there were significant differences between the experimental group Brazil and France and the control group France and without information. In theoretical terms, this research presents a great contribution to the literature in unprecedented reconciliation of the country of origin effect with the EEG neuroscience tool. In practical terms, it suggests a differentiation of marketing actions (advertising, ads, campaigns, availability at the point of sale) on consumer groups

This thesis presents a field experiment on the topic of ethnic discrimination in the contact between citizens and local Swedish politicians. A correspondence technique was used to investigate whether ethnicity affects how responsive Municipal Commissioners are to questions regarding school politics. By sending an email to each Municipal Commissioner, randomising whether a putative Arabic or Swedish alias was used, it aimed to find potentialpatterns in how different groups of citizens are treated by their local political representatives. In total, eight fictitious individuals were created which each contained a unique mixture of ethnicity, gender and socioeconomic status. In general, the result shows no statistically significant signs of discrimination of individuals with Arabic-sounding names. Evidence of gender disparities among Arabic individuals was neither found. However, Arabic females are significantly less likely to receive a reply than Swedish females. Furthermore, the result indicates that socioeconomic status affects political responsiveness toward individuals with Arabic background. This should be considered problematic and noteworthy in the case of Sweden, given its reputation of being a highly egalitarian and well-functioning democracy. The findings further stress the importance to acknowledge that different categories of social identities may interact with ethnic discrimination. This consequently calls upon appropriate approaches to study it.

As variáveis utilizadas foram encontradas em teorias referentes a marketing e redes sociais, com o o objetivo de coletar estudos recentes para verificar o que estava sendo aprofundado no campo de marketing. Como as redes sociais são muito procuradas pelos consumidores, as marcas no varejo têm demonstrado interesse em atuar dentro das redes sociais, buscando construir e manter um relacionamento mais interativo com os usuários (LABRECQUE, 2014). Tendo isso em mente, foi realizada uma etapa documental para acompanhamento de conteúdos postados por uma marca, para que uma pesquisa experimental fosse arquitetada a partir de lacunas verificadas na literatura. Sendo assim, as variáveis independentes: hedonismo, vivacidade e intimidade com a marca foram utilizadas como estímulos no experimento, através de vídeos de uma marca situada no varejo, por este formato ser verificado como mais interativo em redes sociais. Através destes estímulos, buscou-se verificar a existência de impacto destes sobre as variáveis dependentes: valor de marca, intenção de compra, boca a boca virtual e engajamento com a marca. Tais variáveis estão relacionadas aos estudos que envolvem marketing e redes sociais, verificados na literatura. A partir deste cenário, as rodadas de experimento foram realizadas em quatro grupos diferentes, sendo uma para cada estímulo para fins de efeito principal e um grupo para o efeito neutro, para fins do efeito placebo. A amostra é proveniente de alunos do curso de graduação em administração da Universidade do Vale do Rio dos Sinos (Unisinos), e contou com 136 participantes no total. Os dados coletados foram analisados a partir dos testes estatísticos ANOVA e CHI QUADRADO. Os resultados demonstraram que as variáveis independentes impactaram as variáveis dependentes. A variável que mais impactou foi a intimidade com a marca, sendo aceita todas as hipóteses relacionadas. Portanto, os usuários estimulados com vídeos que possuem conteúdos que remetem à intimidade com a marca, tem maior propensão a atribuir valor de marca, realizar o boca a boca virtual através das redes sociais, engajar-se com a marca, assim como frequentar mais a loja da marca. Comprova-se que conteúdos pensados para redes sociais que envolvem marcas, trazem resultados positivos para as organizações. Os resultados desta pesquisa podem auxiliar os gerentes de marketing em organizações varejistas para investir em ações em redes sociais e realizar projetos que envolvam novos formatos de mídia. / This study is inserted in the marketing and retail field counting on a social networking trend. The research aims to verify the impact of marketing activities on social networks, using a well known brand situated in the retail market for an experiment performing. The variables used were found in theories relating marketing and social networks, with the aim of collecting recent studies to check what was being developed in the marketing field. As consumers are heavily inserted in the social networks, brands in retail have shown interest in acting within social networks, aiming to build and maintain a more interactive relationship with users (Labrecque, 2014). According to this, a documental stage was performed to verify the contents posted on Facebook by a brand. After this stage, an experimental research was architected according to the gaps found in the literature. Thus, the independent variables: hedonism, vividness and brand intimacy were used as stimuli in the experiment, through videos from a retail brand, which is a format that was verified as more interactive on social networks. Through these stimuli, it was possible to verify the existence of impacts on the dependent variables: brand equity, sales performance, word of mouth and brand engagement. These variables are related to studies involving marketing and social networks in the literature. From this scenario, the experiment rounds were held in four different groups, one for each stimulus for priming effect purposes and one for the neutral effect, making the placebo effect. The sample is from business management undergraduate degree students from Universidade do Vale do Rio dos Sinos (Unisinos), and was attended by 136 participants in total. The data were analyzed using ANOVA and CHI SQUARE statistical tests. The results show that the independent variables actually impact the dependent variables. The variable that most impacted was the brand intimacy, accepting all the hypothesis related. Therefore, users stimulated with videos that have brand intimacy content, are more likely to assign brand equity, perform the word of mouth through social networks, engage with the brand, as well as go to the shop of the brand to check on products. This research proves that the content prepared for social networks involving a brand, brings positive results for organizations. The findings of this research can help marketing managers in retail organizations to invest in social network actions and carry out projects involving new media formats.

Comparative experiments, in which subjects are randomized to one of two treatments, are performed often. There is no shortage of papers testing whether a treatment effect exists and providing confidence intervals for the magnitude of this effect. While it is well understood that the object and scope of inference for an experiment will depend on what assumptions are made, these entities are not always clearly presented. We have proposed one possible method, which is based on the ideas of Jerzy Neyman, that can be used for constructing confidence intervals in a comparative experiment. The resulting intervals, referred to as Neyman-type confidence intervals, can be applied in a wide range of cases. Special care is taken to note which assumptions are made and what object and scope of inference are being investigated. We have presented a notation that highlights which parts of a problem are being treated as random. This helps ensure the focus on the appropriate scope of inference. The Neyman-type confidence intervals are compared to possible alternatives in two different inference settings: one in which inference is made about the units in the sample and one in which inference is made about units in a fixed population. A third inference setting, one in which inference is made about a process distribution, is also discussed. It is stressed that certain assumptions underlying this third type of inference are unverifiable. When these assumptions are not met, the resulting confidence intervals may cover their intended target well below the desired rate. Through simulation, we demonstrate that the Neyman-type intervals have good coverage properties when inference is being made about a sample or a population. In some cases the alternative intervals are much wider than necessary on average. Therefore, we recommend that researchers consider using our Neyman-type confidence intervals when carrying out inference about a sample or a population as it may provide them with more precise intervals that still cover at the desired rate.
