Como distintas pedagogias entram em funcionamento nos espaços-tempos noturnos da metrópole? Para responder tal questão, o objetivo principal desta tese consistiu em dar visibilidade às pedagogias que se configuram e operam na noite da cidade de Porto Alegre, RS, Brasil. Para tanto, a pesquisa tratou de investigar como determinados lugares públicos noturnos proporcionam condições que ensejam experiências de aprendizagem implicadas com o que denomino pedagogias da noite. Posicionada no campo dos Estudos Culturais em Educação e partindo de pressupostos teóricos acerca das transformações culturais destacadas por S. Hall, T. Eagleton, Z. Bauman e R. Williams, a pesquisa se insere nas discussões levantadas por autores como H. Giroux, S. Steinberg, E. Ellsworth, M. V. Costa. V. C. Camozzato e P. D. Andrade em torno da pluralização do conceito de pedagogia e de seus espaços de atuação. O primeiro movimento da pesquisa procurou mapear representações da noite no campo das Artes, bem como nas produções das Ciências Humanas e Sociais em que o tema tem sido objeto de estudo. Tal levantamento evidenciou diferentes olhares, tanto para a formação de imaginários noturnos quanto para a diversidade de experiências vividas na noite, sugerindo distintos modos de condução em seus espaços-tempos. O segundo movimento consistiu nas saídas de campo em que o pesquisador-flâneur traçou rotas noturnas na região central de Porto Alegre. Os lugares noturnos selecionados foram três viadutos, duas ruas de um bairro boêmio e um grande parque da cidade. A pesquisa fez uso de uma metodologia de investigação híbrida, utilizando procedimentos inspirados na “etnografia pós-moderna” praticada por S. Gottshalk, na técnica da “observação casual” descrita por Lorite García e na “metodologia polifônica” adotada por M. Canevacci. O corpus de análise foi composto a partir das observações e registros das práticas sociais noturnas e dos relatos de sujeitos abordados nos lugares investigados. Viver na solidão, apegar-se aos pertences pessoais e protegê-los, assim como a desconfiança, resultam de aprendizagens daqueles que habitam nos viadutos à noite. Nas ruas boêmias, a adoção de formas estéticas, os encontros e a busca de relacionamentos afetivos são comportamentos aprendidos nas pedagogias da noite. Aprender a conhecer as intenções do outro pelo uso de “táticas” e “habilidades” realçaram-se como experiências no convívio laboral noturno. Comum a todos os lugares e relatos, evidenciaram-se experiências em que o medo e a insegurança promovem aprendizagens para a proteção na vida urbana noturna. Autores como R. Sennett, M. Canevacci, M. Maffesoli, Yi Fu-Tuan, M. Certeau, J. Larrosa e D. W. Winnicott embasaram as discussões analíticas. A relação do “eu” com o outro e com o lugar foi identificada como linha mestra das experiências de aprendizagem desenvolvidas por meio das condições exteriores e de como são interiorizadas pelos sujeitos. Intrínsecos aos modos de viver e aprender, esses movimentos de “exteriorização” e “interiorização” permitiram visualizar como as pedagogias se configuram e operam na noite. Funcionando como movimentos de articulação, as pedagogias da noite ensejam experiências em que os sujeitos aprendem tanto a conduzir quanto a conduzir-se e serem conduzidos nas situações e condições que determinados lugares noturnos da metrópole proporcionam. / How different pedagogies work in the metropolis nocturnal time space? In order to answer this question, the main objective of this thesis consists of give visibility to the pedagogies that are configured and operate in the night of Porto Alegre city, RS, Brazil. Therefore, the research sought to investigate how certain nocturnal public places provide conditions that entice learning experiences implied with what I call pedagogies of the night. Inscribed in the field of Cultural Studies in Education and based on theoretical assumptions about the cultural transformations highlighted by S. Hall, T. Eagleton, Z. Bauman and R. Williams, the research is inserted in the discussions raised by authors such as H. Giroux, S Steinberg, E. Ellsworth, MV Costa. V. C. Camozzato and P. D. Andrade around the pluralization of pedagogy concept and its spaces of acting. The first research movement pursued to map the representations of the night in the Arts field, as well as in the productions of Social and Human Sciences in which the subject has been object of study. This collection evidenced the different views, both for the nocturnal imaginaries formation and for the diversity of experiences lived at night, suggesting different modes of conduction in their time-spaces. The second movement consisted of field outing in which the researcher-flâneur traced nocturnal routes in the central region of Porto Alegre. The selected night spots were three viaducts, two streets of a bohemian neighborhood and a large city park. The research used a hybrid research methodology, utilizing procedures inspired by the "postmodern ethnography" practiced by S. Gottschalk, by the "casual observation" technique described by Lorite García and by "polyphonic methodology" adopted by M. Canevacci (2005). The corpus of analysis was composed from the observations and records of the nocturnal social practices and the subject’s reports approached in the investigated places. Living in solitude, clinging to personal belongings and protecting them, as well as the distrust, result as learnings of those who inhabit viaducts at night. In the bohemian streets, the adoption of aesthetic forms, the encounters and the search for affective relationships are behaviors learned in the pedagogies of the night. Learning to know each other's intentions through the use of "tactics" and "abilities" have been emphasized as experiences in the life at night. Common to all places and reports, there have been experiences in which fear and insecurity promote learning for protection in the urban night life. Authors like R. Sennett, M. Canevacci, M. Maffesoli, Yi Fu-Tuan, M. Certeau, J. Larrosa and D. W. Winnicott supported the analytical discussions. The relation of the "self" to the other and with the place was identified as the main line of learning experiences developed through external conditions and how they are internalized by the subjects. Intrinsic to the ways of living and learning, these movements of "exteriorization" and "interiorization" allowed to visualize how the pedagogies are configured and operate at night. Functioning as articulation movements, the pedagogies of the night provide experiences in which the subjects learn to drive and conduct themselves as well as to be conducted in the situations and conditions that certain metropolis nocturnal places provide.

The research problem is the increasing numbers of overweight and obese nurses working the night shift. Study on overweight and obesity among female Filipino nurses has not been conducted. It was important to conduct a research study among female Filipino nurses to find out if there are statistically significant associations between night shift work and weight gain. The purpose of this correlational and cross-sectional study was to determine if there are statistically significant associations between insufficient sleep, abnormal eating patterns, working 12-hour shifts, years of working night shift, age, stress, marital status, nursing units, decreased physical activity, and level of weight gain among female Filipino nurses working the night shift in the hospital. The theoretical base of this study was the locate evidence, evaluate evidence, assess evidence, and informed decision model. The survey questionnaire was constructed and an online survey through Survey Monkey was used to access nurses via a convenience sampling. Data were analyzed using Spearman correlation, multiple regression, and ANOVA. According to study findings, there were significant associations between insufficient sleep, abnormal eating patterns, marital status, 12-hour shifts, number of years working on night shift, and increased in body mass index. The implications for social change include information that nurses can use to better understand the negative implications of night shift work on health. At the organizational level, this study provides information for administrators and nursing leaders that might facilitate change in policies by improving working conditions for nurses.

I denna studie undersöker vi de främsta anledningarna till att medieteknikstudenter på KTH (Kungliga Tekniska Högskolan) använder blåljusfilter. Då man som medieteknikstudent använder elektroniska enheter under sina studier är det relevant att undersöka de vanor som studenterna har i deras användande och förstå anledningen bakom deras vanor. 17 studenter intervjuades med frågor kopplade till användningen av blåljusfilter där en del av intervjun fokuserade på den intervjuades vanor i användandet medan den andra delen fokuserade på upplevda effekter av användandet. Efter att ha sammanfattat intervjuerna kunde vi sammanställa de anledningar som framkom flest gånger under intervjuernas gång. Det framkom då att den främsta anledningen till att medieteknikstudenter använder blåljusfilter är att deras ögon blir mindre ansträngda, vilket de upplever ökar bekvämligheten framför skärmen. Den näst främsta anledningen var att studenterna ville få bättre sömnvanor. De främsta anledningarna till att medieteknikstudenter använder blåljusfilter är samma anledningar till att blåljusfilter rekommenderas och dessa anledningar stämmer överens med teorin. Anledningarna kan motivera personer som spenderar mycket tid framför skärmar att testa på denna vana om de upplever ett behov av mindre ansträngda ögon eller sömnvanor. / This study examines the main reasons behind why media technology students at KTH (Royal Institute of Technology) use blue light blocking filters on their technical devices. Since technical devices are frequently used during the studies of media technology it’s interesting to discover more about the habits in front of the screens and the reason behind those habits. 17 students were interviewed with questions related to their habits with the blue light blocking filter. One part of the interview focused more on their everyday usage while the other part where more focused on the experienced effects after using these filters. The interviews were then summarized and the reasons for the usage could be compiled in order to achieve a ranked list that would answer our question. The main reason why media technology students use blue light blocking filters is because it decreases the strain on the eyes, which increases their comfort in front of the screen. The reason that ended up in second place was in order for the students to develop more healthy sleeping habits. The main reasons why media technology students use blue light blocking filters are also the same reasons why these filters are recommended. The reasons also correspond to the previous research that has been done within this area. These reasons can motivate people that spend a lot of time in front of their screens to implement this habit of using a blue light blocking filter if they experience strained eyes or bad sleeping habits.

Background: Binge-eating disorder (BED) as a distinct eating disorder category and night eating syndrome (NES) as a form of Other Specified Feeding or Eating Disorders were recently included in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Objectives: This study sought to investigate the prevalence of BED and NES and associations with various forms of non-normative eating behavior and psychopathology in prebariatric patients. Setting: Within a consecutive multicenter registry study, patients in six bariatric surgery centers in Germany were recruited. Methods: Overall, 233 prebariatric patients were assessed using the Eating Disorder Examination and self-report questionnaires. Assessment was unrelated to clinical procedures. Results: Diagnostic criteria for full-syndrome BED and NES were currently met by 4.3% and 8.2% of prebariatric patients, respectively. In addition, 8.6% and 6.9% of patients met subsyndromal BED and NES criteria, respectively. Comorbid BED and NES diagnoses were present in 3.9% of patients. In comparison to patients without any eating disorder symptoms, patients with BED and NES reported greater emotional eating, eating in the absence of hunger, and more symptoms of food addiction. Moreover, differences between patients with BED and NES emerged with more objective binge eating episodes and higher levels of eating concern, weight concern, and global eating disorder psychopathology in patients with BED. Conclusions: BED and NES were shown to be prevalent among prebariatric patients, with some degree of overlap between diagnoses. Associations with non-normative eating behavior and psychopathology point to their clinical significance and discriminant validity.

This study focused on nurses who work the night shift, and on some of the aspects of their lives. The objectives of the study were to identify and describe these experiences with specific reference to the physical, social and work-related effects.

The high frequency and cost of flooding in Canada has demonstrated the need for effective risk assessment (Public Safety Canada (PSC), 2010). In response to this need, the United States Federal Emergency Management Agency (FEMA) developed HAZUS, a hazard risk assessment tool which relies on a geographic information system (GIS) (FEMA, 2015). Unfortunately, in many rural communities in Canada, only aggregate population data may be available. In those cases, the ability to further partition aggregated data may prove essential in generating robust and accurate risk assessments. The results of this study show that HAZUS can be adapted for use in Canada and provides a new methodology for conducting hazard estimations in areas where available data is coarsely aggregated. There was a strong relationship between nighttime light and population density. High populations were associated with developed land cover classification. These relationships can be used to increase the accuracy of HAZUS predictions. / October 2016

Approved for public release; distribution in unlimited. / Night Vision Devices (NVD) using Image Intensification (II) technology are among the most important sensors used by ground troops and aviators in night operations for modern combat. With the intensified images from these devices, soldiers can see an enemy's movement better and further in darkness. This thesis explores different test methods in evaluating the performances and sensitivities of several NVDs for future image fusion studies. Specification data such as sensitivity, resolution (Modulation Transfer Function) and pixel size are obtained. Comparative analyses of the collected results are made to characterize the performances of the different NVDs. A new method using MATLAB programming to objectively analyze digitized images for characterization of II based NVDs is proposed. This test method can also be extended to the evaluation of Thermal Imaging (TI) systems for comparative analysis with II NVDs. In addition, the feasibility of testing NVDs using both II and TI technologies, with common operating conditions and target boards is discussed. Finally, the potential of using these digitized images for image fusion studies is verified with the test and evaluation results. / Republic of Singapore

Cette thèse examine l’influence de la nuit sur la réception d’une visite de musée. Elle propose d’envisager le paramètre horaire comme participant de la construction de l’expérience et plus largement du sens donné à sa visite. Or, ce rapport de la nuit à l’expérience de visite est encore peu interrogé malgré les nombreuses occasions qui permettent de visiter de nuit des institutions culturelles telles que les musées ou les monuments historiques. L’analyse phénoménologique et sémiotique de cette situation de réception permet de comprendre ce que les visiteurs vivent et ressentent au cours d’une visite nocturne. Elle révèle une variation du sens qui se construit autour de l’émergence de la nuit à la fois comme donnée physique, naturelle, dans l’exposition et comme donnée mentale dans l’état d’esprit des visiteurs. À travers l’étude comparative de la réception de la cour Marly au musée du Louvre, de jour et de nuit, c’est l’univers du discours des visiteurs qui est mis en question. Les interactions entre la nuit, les visiteurs et l’exposition marquent, par rapport à la journée, un processus de transformation du sens donné par le message de l’exposition et du sens reçu par les visiteurs. Autrement dit, le changement lumineux intervenant entre jour et nuit influence la recomposition du discours de l’exposition par les visiteurs de nocturnes. La dimension émotionnelle ainsi que la fantasmatique de la nuit interviennent dans l’interprétation du discours de l’exposition et le transforment. / The aim of this work is to analyse the impact of the night on the visitors’experience. Here, the time of the day is considered as a parameter of the processof meaning building within the visitor’s experience.The link between visitors’ experience and night has not yet been thouroughlyresearched although a lot of cultural events take place at night time and provideand occasion for visiting museums.The phenomenological and semiotic analysis of the night impact, and perception,lead to the understanding of the emotional experience of the visitors during anight time visit. It reveals a variation of the meaning created by the apparition ofthe actual night in the museum and of the idea of night in the visitors’ mind.A night and day comparison of the reception of the cour Marly, in the musée duLouvre, questions the visitors’ speeches. It shows a network of interactionsbetween the night, the visitors and the exhibition which initiates a transformationof the meaning given by the exhibition and received by the visitors.In other words, the lighting modification between night and day affects thereconstruction of the exhibition’s message operated by the visitors at night. Theemotional aspect as well as the night phantasmagoria partake in the interpretationof the exhibition’s message and change it.Key words: night - reception - visitors’ experience - interpretation - - - - - phantasmagoria - night visit
