Aspects of User Experience on WikiCI Website

Artigo apresentado no I Workshop de Informação, Dados e Tecnologia, realizado entre nos dias 04 e 06 de setembro de 2017, na cidade de Florianópolis (SC), no Auditório do Espaço Físico Integrado (EFI) da Universidade Federal de Santa Catarina (UFSC).Os usuários têm produzido cada vez mais conteúdo dentro de ambientes colaborativos, com isso, é imprescindível que sua experiência dentro desses ambientes seja a mais satisfatória possível. Para tal, a Arquitetura da Informação (AI) junto a Ciência da Informação (CI) tem a finalidade de proporcionar o equilíbrio das necessidades do usuário, emergindo no contexto do sentimento do usuário, suas alegrias e frustrações, questões que podem ser interpretadas pela Experiência de Usuário (User Experience – UX). Este trabalho tem como objetivo analisar aspectos da AI, especificamente em relação à aderência do portal WikiCI aos princípios determinados pela UX. Como metodologia foi adotada uma análise qualitativa, de caráter exploratório, onde utilizou-se de pesquisa bibliográfica para explanar os conceitos da UX em ambientes digitais, e com isso foi realizada a avaliação dos elementos da WikiCI segundo as facetas da UX. Por meio da análise realizada neste trabalho, observou-se que a aderência da WikiCI aos princípios da UX mostrou-se adequada, pois o website apresenta elementos que podem ser observados nas facetas da UX. Conclui-se que, para os usuários terem uma experiência totalmente satisfatória, é relevante que desenvolvedores de websites atentem-se às questões da AI, e principalmente aos princípios determinados pela UX.Users have been producing more and more content inside of collaborative environments, so it is indispensable that their experience inside these environments is as satisfactory as possible. For this, Information Architecture (AI) together with Information Science (CI) has the purpose to providing the balance of user needs, emerging in the context of user’s feeling, their joys and frustrations, issues that can be interpreted by the User Experience (UX). This work has a objective to analyze aspects of AI, specifically regarding the adherence of the WikiCI website to the principles determined by UX. As methodology was adopted a qualitative analysis, of exploratory character, where it used bibliographical research to explain the concepts of UX in digital environments, and it was carried out rating of the elements of the WikiCI according to the facets of UX. Through the analysis conducted in this work, it was observed that the adherence of the WikiCI to the principles of UX proved to be adequate, because the website presents elements that can be observed in the facets of UX. it is relevant that website developers attend to AI questions, and especially to the principles determined by UX

Glitchspace:teaching programming through puzzles in cyberspace

There is an increasing need to address the player experience in games-based learning. Whilst games offer enormous potential as learning experiences, the balance between entertainment and education must be carefully designed and delivered. Successful commercial games tend to focus gameplay above any educational aspects. In contrast, games designed for educational purposes have a habit of sacrificing entertainment for educational value which can result in a decline in player engagement. For both, the player experience is critical as it can have a profound effect on both the commercial success of the game and in delivering the educational engagement. As part of an Interface-funded research project Abertay University worked with the independent games company, Space Budgie, to enhance the user experience of their educational game Glitchspace. The game aimed to teach basic coding principles and terminology in an entertaining way. The game sets the player inside a Mondrian-inspired cyberspace world where to progress the player needs to reprogramme the world around them to solve puzzles. The main objective of the academic-industry collaborative project was to analyse the user experience (UX) of the game to increase its educational value for a standalone educational version. The UX design focused on both pragmatic and hedonic qualities such playability, usability and the psychological impact of the game. The empirical study of the UX design allowed all parties to develop a deeper understanding of how the game was being played and the initial reactions to the game by the player. The core research question that the study sought to answer was whether when designing an educational game, UX design could improve philosophical concepts like motivation and engagement to foster better learning experiences.</p

First-principles study of epitaxial strain in perovskites

Using an extension of a first-principles method developed by King-Smith and Vanderbilt [Phys. Rev. B {\bf 49}, 5828 (1994)], we investigate the effects of in-plane epitaxial strain on the ground-state structure and polarization of eight perovskite oxides: BaTiO$_3$, SrTiO$_3$, CaTiO$_3$, KNbO$_3$, NaNbO$_3$, PbTiO$_3$, PbZrO$_3$, and BaZrO$_3$. In addition, we investigate the effects of a nonzero normal stress. The results are shown to be useful in predicting the structure and polarization of perovskite oxide thin films and superlattices.Comment: 10 page

Reichenbach's Common Cause Principle in Algebraic Quantum Field Theory with Locally Finite Degrees of Freedom

In the paper it will be shown that Reichenbach's Weak Common Cause Principle is not valid in algebraic quantum field theory with locally finite degrees of freedom in general. Namely, for any pair of projections A and B supported in spacelike separated double cones O(a) and O(b), respectively, a correlating state can be given for which there is no nontrivial common cause (system) located in the union of the backward light cones of O(a) and O(b) and commuting with the both A and B. Since noncommuting common cause solutions are presented in these states the abandonment of commutativity can modulate this result: noncommutative Common Cause Principles might survive in these models

Noncommutative Common Cause Principles in Algebraic Quantum Field Theory

States in algebraic quantum field theory "typically" establish correlation between spacelike separated events. Reichenbach's Common Cause Principle, generalized to the quantum field theoretical setting, offers an apt tool to causally account for these superluminal correlations. In the paper we motivate first why commutativity between the common cause and the correlating events should be abandoned in the definition of the common cause. Then we show that the Noncommutative Weak Common Cause Principle holds in algebraic quantum field theory with locally finite degrees of freedom. Namely, for any pair of projections A, B supported in spacelike separated regions V_A and V_B, respectively, there is a local projection C not necessarily commuting with A and B such that C is supported within the union of the backward light cones of V_A and V_B and the set {C, non-C} screens off the correlation between A and B
