Contemporary museum spaces Interactions between visible and invisible dimensions Abstract: It can be considered that the contemporary organization of the museum’s program is divided into two different dimensions. The first relates to the concepts of displaying, disclosing and exhibiting and consists in the exhibition and public reception spaces. The second dimension comprises reservations and the technical and administrative services of the museum. At the visitor’s eye’s, these two dimensions of the museum can be defined as visible and invisible. In this context, the present dissertation analyzes, from the architectural point of view, how both dimensions can interact and the way that invisible dimension can be unveiled; ESPAÇOS MUSEOLÓGICOS CONTEMPORÂNEOS Interações entre a dimensão visível e a dimensão invisível Resumo: Pode considerar-se que a organização contemporânea do programa do museu se divide em duas dimensões.

Este artigo procura contribuir para a compreensão da relação entre os conceitos de presenteísmo e de comportamento organizacional positivo. Neste âmbito, pretende-se avaliar a relação entre duas facetas do presenteísmo (trabalho completado e distracção evitada) e uma dimensão de capital psicológico positivo (esperança). Recorreu-se a uma amostra de 158 colaboradores, maioritariamente associados às áreas da saúde e investigação. Os resultados revelam que a faceta de presenteísmo distracção evitada encontra-se associada ao grupo de trabalhadores com baixos resultados na variável esperança. Sugerem-se propostas de implementação de programas de redução do presenteísmo, com o objectivo de incrementar o capital psicológico positivo das organizações. Este estudo permitiu ainda apresentar as boas qualidades métricas da escala Stanford Presenteeism Scale (SPS-6). Tratando-se de um estudo pioneiro,

O propósito desta pesquisa foi investigar o papel atribuído à Dança, no âmbito da dimensão afetivossocial compreendendo como se reflete na vida (pessoal e social) dos jovens estudantes dos oito Centros de Pesquisa e Formação em Ensino Escolar de Arte e Esporte – Núcleo de Arte da Prefeitura do Rio de Janeiro – distribuídos em distintas regiões do município do Rio de Janeiro. A base teórica do estudo foi fundamentada pela dimensão afetivossocial em autores de referência da área (Bertine, 2014; Damásio, 2012; 2013; Godoy, 2013; Leme, 2013; Macara 2010a, 2010b; Marques, 2010; 2014; Matos & Tomé, 2012; Monteiro, 2012; Shapiro, 2008; Stinson, 2014; Strongman, 2002; Sawaia, 2014; Varregoso et al., 2014). Com este desígnio, o trajeto metodológico percorrido para construção da tese decorreu em duas fases. A primeira de natureza exploratória, marcada por dois Estudos Preliminares. A segunda de natureza pluri-metodológicos: Pesquisa de Método Misto, com a combinação entre a abordagem quantitativa e qualitativa, marcada por um estudo de campo. Participaram do estudo quantitativo 378 praticantes de Dança de 12 a 18 anos de idade e do estudo qualitativo 52 integrantes do espaço (diretores, professores, coordenador e praticantes e ex-praticantes). O método de análise adotado foi estatístico descritivo e correlação de Pearson pelo SPSS22 e, análise de conteúdo. Todos os dados analisados foram integrados nas duas dimensões do estudo, Dimensão Representação Afetivossocial e Dimensão Transformação Pessoal e Social. Como resultado, verificamos que os jovens sentem-se motivados e incluídos pelo trabalho realizado nas oficinas de Dança nos núcleos, percebem que a Dança é fonte de empoderamento da dimensão afetivossocial pelo despertar da motivação, do bem-estar e da autorealização. No campo afetivo, descrevem o desenvolvimento das competências emocionais pelas sensações, emoções e sentimentos gerados no corpo e nas experiências relacionais na Dança, despertando o conactus (Damásio, 2012; Leme, 2013) e a potência de ação (Sawaia, 2014), capazes de transformar estados emocionais, situações e coisas em benefício próprio. O desenvolvimento das competências sociais transcorreu pela mudança comportamental em casa, pela tríade interação-participação-transformação social no núcleo, família, escola e comunidade despertando sentimentos na construção da dimensão afetivossocial e promovendo liberdade de ser e estar no mundo. Com o desenvolvimento destas competências, estes jovens percebem-se incluídos na sociedade despertando para muitos o desejo de prosseguimento na carreira (Amadora ou Profissional).

This thesis presents studies of the role of disorder in non-equilibrium quantum systems. The quantum states relevant to dynamics in these systems are very different from the ground state of the Hamiltonian. Two distinct systems are studied, (i) periodically driven Hamiltonians in two dimensions, and (ii) electrons in a one-dimensional lattice with power-law decaying hopping amplitudes. In the first system, the novel phases that are induced from the interplay of periodic driving, topology and disorder are studied. In the second system, the Anderson transition in all the eigenstates of the Hamiltonian are studied, as a function of the power-law exponent of the hopping amplitude.
In periodically driven systems the study focuses on the effect of disorder in the nature of the topology of the steady states. First, we investigate the robustness to disorder of Floquet topological insulators (FTIs) occurring in semiconductor quantum wells. Such FTIs are generated by resonantly driving a transition between the valence and conduction band. We show that when disorder is added, the topological nature of such FTIs persists as long as there is a gap at the resonant quasienergy. For strong enough disorder, this gap closes and all the states become localized as the system undergoes a transition to a trivial insulator.
Interestingly, the effects of disorder are not necessarily adverse, disorder can also induce a transition from a trivial to a topological system, thereby establishing a Floquet Topological Anderson Insulator (FTAI). Such a state would be a dynamical realization of the topological Anderson insulator. We identify the conditions on the driving field necessary for observing such a transition. We realize such a disorder induced topological Floquet spectrum in the driven honeycomb lattice and quantum well models.
Finally, we show that two-dimensional periodically driven quantum systems with spatial disorder admit a unique topological phase, which we call the anomalous Floquet-Anderson insulator (AFAI). The AFAI is characterized by a quasienergy spectrum featuring chiral edge modes coexisting with a fully localized bulk. Such a spectrum is impossible for a time-independent, local Hamiltonian. These unique characteristics of the AFAI give rise to a new topologically protected nonequilibrium transport phenomenon: quantized, yet nonadiabatic, charge pumping. We identify the topological invariants that distinguish the AFAI from a trivial, fully localized phase, and show that the two phases are separated by a phase transition.
The thesis also present the study of disordered systems using Wegner's Flow equations. The Flow Equation Method was proposed as a technique for studying excited states in an interacting system in one dimension. We apply this method to a one-dimensional tight binding problem with power-law decaying hoppings. This model presents a transition as a function of the exponent of the decay. It is shown that the the entire phase diagram, i.e. the delocalized, critical and localized phases in these systems can be studied using this technique. Based on this technique, we develop a strong-bond renormalization group that procedure where we solve the Flow Equations iteratively. This renormalization group approach provides a new framework to study the transition in this system.

On most if not all evaluatively relevant dimensions such as the temperature level, taste intensity, and nutritional value of a meal, one range of adequate, positive states is framed by two ranges of inadequate, negative states, namely too much and too little. This distribution of positive and negative states in the information ecology results in a higher similarity of positive objects, people, and events to other positive stimuli as compared to the similarity of negative stimuli to other negative stimuli. In other words, there are fewer ways in which an object, a person, or an event can be positive as compared to negative. Oftentimes, there is only one way in which a stimulus can be positive (e.g., a good meal has to have an adequate temperature level, taste intensity, and nutritional value). In contrast, there are many different ways in which a stimulus can be negative (e.g., a bad meal can be too hot or too cold, too spicy or too bland, or too fat or too lean). This higher similarity of positive as compared to negative stimuli is important, as similarity greatly impacts speed and accuracy on virtually all levels of information processing, including attention, classification, categorization, judgment and decision making, and recognition and recall memory. Thus, if the difference in similarity between positive and negative stimuli is a general phenomenon, it predicts and may explain a variety of valence asymmetries in cognitive processing (e.g., positive as compared to negative stimuli are processed faster but less accurately). In my dissertation, I show that the similarity asymmetry is indeed a general phenomenon that is observed in thousands of words and pictures. Further, I show that the similarity asymmetry applies to social groups. Groups stereotyped as average on the two dimensions agency / socio-economic success (A) and conservative-progressive beliefs (B) are stereotyped as positive or high on communion (C), while groups stereotyped as extreme on A and B (e.g., managers, homeless people, punks, and religious people) are stereotyped as negative or low on C. As average groups are more similar to one another than extreme groups, according to this ABC model of group stereotypes, positive groups are mentally represented as more similar to one another than negative groups. Finally, I discuss implications of the ABC model of group stereotypes, pointing to avenues for future research on how stereotype content shapes social perception, cognition, and behavior.

The purpose of this study was to examine whether leadership can be learned through the Community Recreation and Leadership Training (CRLT) program and how effective the program is in terms of changing the perceptions and abilities of the students. The intentions of the researcher were to discover crucial learning moments as perceived by students and to gain insights that could lead to future improvements to enhance and enrich learning in a leadership program. To continue to be a viable program and to keep step with the demands of the recreation/leisure industry and society's wide-ranging needs, this study may help to inform the program's 'action plan' for continued success. This study employed a mixed method approach to determine how college students develop effective leadership ability in a three-year Community Recreation and Leadership Training (CRLT) college career program. First, a number of statistical tests were carried out to examine the four research questions used to guide the study. The SPSS software was used to analyze the data collected. The first research question asked how perceptions of leadership change as a result of being in a three-year leadership program. This study, using the Student Leadership Practice Inventory (SLPI), compared the five SLPI leadership dimensions by year. The SLPI was administered to all the first, second, and third year CRLT students ( N = 84). A one-way analysis of variance in participants' scores was conducted. No significant differences were revealed in any of the five dimensions of the SLPI among the first, second, and third year students at p < .05. However, two dimensions (model and encourage) approached significance and may hint at a possible influence the program is having on its students as they progress into the third year. The second research question asked whether perceptions of leadership vary by gender. Comparing the mean scores between the males and females on the five dimensions of the SLPI, no significant differences were found. The third research question asked whether prior leadership experience results in better academic performance for CRLT students in their 1st term. A one-way analysis of variance was conducted to evaluate the relationship between prior leadership experience and mean scores on academic performance. No significant correlations were found between grades and low, medium, or high levels of prior leadership experience F(2,79) = 2.67, p = .08. A correlation coefficient was also computed to determine whether there was a relationship between the Recreation Leadership I course grade and prior leadership experience. The correlation coefficient (.02) was statistically significant, r(80) = .24, p < .05. However, further studies with a larger sample size would be necessary to help determine this. The fourth question asked whether there was a correlation between students' first semester grades and their scores on the Student Leadership Practice Inventory (SLPI). Bivariate correlations (Pearson) were computed for the five SLPI dimensions with academic performance. None of the correlations using the five SLPI indicators was significant. Qualitative data was examined to discover what factors and experiences help students to assert a more effective leadership role. The study relied on content analysis of personal statements, and focus groups. Student perceptions of an effective leader, students' perceptions of their own abilities, and the strengths of the program were explored. A content analysis of the 'Personal Statements' was carried out to determine how students defined leadership prior to their having had any formal teaching in a college program. The result of the analysis of personal statements provided eight leadership categories used as an initial baseline for the study. Six focus groups (totaling N = 30) were conducted. Students responded to four key questions: how they define leadership. What is the single most effective quality of a leader? What leadership skills did they feel they had gained? How had the program helped them obtain their skills? Students credited the CRLT program with helping them develop a variety of leadership skills. Students revealed that they had gained skills such as confidence, knowledge and understanding of people's needs, and becoming more self-directed. They attributed their skill development to such things as good course design, intensive outdoor education and fieldwork courses, "hands on" learning approaches, group work, skill practice, the support they received from teachers, and encouragement they were given by their peers. A common finding among genders was defining an effective leader as someone who is "confident". However, the definition of the most important quality of a leader varied by gender. While males showed a tendency to prefer a leader being "confident," females preferred a leader being a "teacher".

Declarative techniques such as Constraint Programming can be very effective in modeling and assisting management decisions. We present a method for managing university classrooms which extends the previous design of a Constraint-Informed Information System to generate the timetables while dealing with spatial resource optimization issues. We seek to maximize space utilization along two dimensions: classroom use and occupancy rates. While we want to maximize the room use rate, we still need to satisfy the soft constraints which model students’ and lecturers’ preferences. We present a constraint logic programming-based local search method which relies on an evaluation function that combines room utilization and timetable soft preferences. Based on this, we developed a tool which we applied to the improvement of classroom allocation in a University. Comparing the results to the current timetables obtained without optimizing space utilization, the initial versions of our tool manages to reach a 30% improvement in space utilization, while preserving the quality of the timetable, both for students and lecturers.

The research investigates the interaction between social innovation practices and urban planning, assuming as a case study and field of application the city of Bologna, observed from the point of view of the production of urban policies and with respect to the places where it is practiced. Social innovation are localised actions tackling current urban complexities with micro-scale practices of service and urban production, by which new urban actors find answers to social needs, which are less afforded by the market and the public sectors. Planning and social innovation practices are two dimensions working in the city in different but complementary ways, subject to a mismatch. Through the lenses of interaction, the research explores the context of Bologna, a paradigmatic study and application field, a laboratory of innovative policies where a tradition of collective civic initiatives intertwines with a more responsible institutional planning framework. After drawing from area-based policies of Berlin and Barcelona, the thesis reads the role of specific intermediate places, mediators in bridging the level of institutions and the practices. Through an inventory and a cross-cutting taxonomy of intermediate places, the research draws the knowledge to inform a new urban model for the city of Bologna, aimed at overtake the mismatches by enabling the practices to act, allowing urban planning to frame them in a cross-fertilisation dimension. The proposed urban diagrammatic model, foresees intermediate places as local socio-urban observatories for research and development, interacting with both institutions and communities. The goal is to critically explore the limits and widen the meaning of the capacity of action of social innovation practices engaging in mutual-learning with the city. The model suggests a new possibility for reflection on urban planning as a more flexible approach, which translates the numerous experiences of the city into alternatives and multiple visions.
