Dentro do conjunto de aspectos relacionados à elaboração de projetos em estruturas de aço e mistas de aço e concreto, destaca-se como de grande importância e interesse, para fins de dimensionamento, a consideração de elementos estruturais submetidos a temperaturas elevadas. Nesse sentido, o presente trabalho tem como objetivo principal propor a construção de modelos numéricos tridimensionais de pilares de aço pertencentes a sistemas estruturais correntes da construção civil, para análise em situação de incêndio, com vistas a simular numericamente a evolução dos níveis de temperatura ao longo do tempo com posterior acoplamento termoestrutural. Considera-se uma análise paramétrica com vista a variar as restrições axiais totais e parciais da barra, no referente aos deslocamentos axiais, contemplando desde a situação de extremidade livre até a restrição completa em resposta à consideração de apoio do tipo fixo, por exemplo. Os resultados numéricos são comparados a ensaios experimentais de outros autores, bem como com outros trabalhos numéricos já publicados. São obtidas respostas de deslocamentos axiais e laterais do modelo termoestrutural para diversas disposições de paredes em relação ao perfil, bem como gráficos do acréscimo de força axial introduzido no sistema pela restrição axial. Os estudos aqui realizados poderão servir como base para novas pesquisas tanto no campo numérico quanto experimental, assim como para futuras revisões da ABNT NBR 14323:1999, buscando contemplar situações de interesse não abordadas neste documento normativo. Os resultados da pesquisa apontam que a consideração do campo térmico com a inclusão da alvenaria no modelo termoestrutural pode melhorar consideravelmente o desempenho do elemento estrutural em situação de incêndio. / Within the set of aspects related to the development of researches in steel and composite steel and concrete structures, stands out with great importance and interest, aiming to dimension, the consideration of structural elements subjected to high temperatures. In this way, the present work has as main objective to propose the construction of three-dimensional numerical models of steel columns that belong to current structural systems of civil construction, for examination in fire situation, aiming to simulate numerically the evolution of temperature levels throughout of time with later termoestrutural coupling. It will be considered a parametric analysis in order to vary the total and partial axial restraint in respect to the axial displacements, since the free end situation until the complete restriction in response to the consideration of support for the fixed type, for example. The numerical results are compared to experimental tests made by other authors, as well as with others numerical works already published. Answers are obtained from axial and lateral displacements of the thermo structural model to many displacement of wall related to the profile, also charts of adding axial force introduced into the system by the axial restraint. The results of the current research could serve as a basis for further research in both the numerical field or experimental, also for future revisions of ABNT NBR 14323:1999, aiming to see situations of interest not studied in the same normative document. The results of this work show that consideration of thermal field with the inclusion of masonry in the thermo structural model can, significantly, improve the performance of the structural element in a fire situation.

O presente trabalho examina o chamado problema da indeterminação jurídica, de maneira a procurar explicitar o tipo de questões teóricas que suscita e apreciar o alcance ou fecundidade das respostas que tais questões possibilitam, sobretudo sob o ângulo da discussão dos pressupostos institucionais subjacentes à organização das atividades de aplicação do direito. Nesse contexto, a tese central do trabalho é a de que a ideia de indeterminação do direito, restrita ao contexto jurisdicional e entendida como um fenômeno linguístico, esgotou seu potencial teórico, e que a percepção desse esgotamento deveria conduzir à exploração de formas pelas quais questões de indeterminação do direito podem ser mais produtivamente tratadas como questões sobre configuração institucional do que como questões sobre a natureza, ou defeitos, da linguagem. São analisadas abordagens paradigmáticas do problema - no pensamento de Hans Kelsen, H.L.A. Hart e Ronald Dworkin - e os pressupostos institucionais que as informam, assim como identificados pontos de partida, nos estudos de Lon L. Fuller voltados à avaliação de formas alternativas de organização social, para exercícios de inovação institucional. A possibilidade de tais exercícios é exemplificada, ao final do trabalho, com propostas específicas de inovação, elaboradas por autores contemporâneos, concentradas na função jurisdicional, dirigidas a enfrentar o reconhecido impasse entre propostas de expansão e contenção da atuação judicial no contexto de efetivação de direitos sociais de caráter distributivo. / This work analyses the so-called legal indeterminacy problem, in order to make explicit the kind of theoretical issues it engenders and to assess the scope or fecundity of the answers such issues make possible, especially in terms of the discussion of institutional assumptions underlying the organization of the adjudicative function. In this setting, the central claim of this work is that the theoretical potential of the idea of legal indeterminacy, limited to the adjudicative realm and understood mainly as a linguistic phenomenon, has been worn out, and that the acknowledgment of this result should lead to the investigation of ways in which ?legal indeterminacy? issues might be more productively treated as issues about institutional innovation than issues about the nature, or defects, of language. The exemplary works of Hans Kelsen, H.L.A. Hart, and Ronald Dworkin and the institutional assumptions underlying their thought, in connection with the indeterminacy problem, are reviewed, along with the writings of Lon L. Fuller dedicated to the assessment of alternative processes of social ordering, which are taken as a point of departure for exercises in institutional innovation. The possibility of such exercises is illustrated, at the end of this work, with specific innovation proposals by contemporary authors focused on the adjudicative job, dedicated to facing the theoretical deadlock between proposals for expanding and restricting the judicial role in the context of making welfare rights, of a distributive character, concrete

This study examined the effect of an 8-week, progressive exercise intervention on neural responses, specifically N2 amplitude as a measure of inhibitory control, to pictures of food. Healthy women ages 18-44 years were randomized to a morning (AM) exercise group or evening (PM) exercise group. The AM group did moderate-to-vigorous intensity exercise on 4 days per week between 6:30 and 9:30 a.m. while the PM group had the identical volume of exercise between 6:30 and 9:30 p.m. Neural responses, eating behaviors, cardiovascular fitness outcomes, and body weight/composition were measured at baseline and after the 8-week intervention. The N2 amplitude in response to pictures of high- and low-calorie foods was assessed using electroencephalography during a go/no-go task. Dietary restraint, emotional eating, and external eating were assessed using the Dutch Eating Behavior Questionnaire. VO2peak, HRmax, and time to completion were measured during a maximal treadmill test. Body weight was measured on a digital scale, and body composition was measured using dual-energy x-ray absorptiometry. There was not a significant task (go, no-go) × group (AM, PM) × period (baseline, 8 weeks) interaction (F = 0.18; p = 0.677), but there was a main effect of exercise over 8 weeks (F = 6.26; p = 0.017) with increased N2 amplitude following the intervention. There was not a significant interaction as a function of picture type (high-calorie, low-calorie), task, group, and period (F = 0.52; p = 0.478). Changes in body weight and neural outcomes were not significantly associated with changes in eating behaviors for either group (ps < 0.05). There was a significant group × period interaction for body weight (F = 4.90; p = 0.032). Body weight increased by 0.79 ± 1.16 kg in the AM group and decreased by 0.21 ± 1.46 kg in the PM group (effect size = 0.77; CI = 0.15-1.35). There was not a significant group × period interaction for body fat percentage, total body fat or fat-free mass (ps < 0.05). When examining the main effect of exercise on cardiovascular fitness outcomes, VO2peak was not different (F = 1.80; p = 0.187), time-to-completion on treadmill increased (F = 6.51; p = 0.014), and HRmax during the treadmill test was significantly lower (F = 5.49; p = 0.025). This study suggests that 8 weeks of exercise training may increase the inhibitory response to pictures of both high- and low-calorie foods. However, time of day of exercise did not influence this response. Eight weeks of exercise training did not change self-reported dietary restraint, external eating, or emotional eating, and there was no correlation between these eating behaviors and inhibitory control. However, evening exercise was more beneficial for body weight than morning exercise. Given the novelty of this study and its results, additional studies on the influence of time of day of exercise on weight management are needed.

According to the Centers for Medicare and Medicaid Services (CMS), approximately 1.3 million U.S. residents are residing in nursing homes. CMS enforced regulations in the Nursing Home Reform Act. Training in the use of restraints in nursing homes is monitored through the CMS standards. The purpose of this study was to determine whether there was a correlation between training standards of health care practitioners and their use of restraints in nursing homes based on the patterns of citations by RNs and CNAs. Data were collected from Kansas, Louisiana, and Ohio within the CMS Nursing Home Data Compendium. The key research question examined differences in standard training requirements, policies, and citations regarding restraint use in the selected states. The theoretical framework for this study was the social influence theory. The results of the analysis of variance indicated that between 2008 and 2012, there were significant differences in policy and standards requirements for the training of registered nurses and certified nursing assistants regarding restraint use; there was also a relationship between the training of staff and the number of citations of restraint use in Kansas, Louisiana, and Ohio. There were significant (p < .02) variations throughout the 3 states regarding the policies, procedures, and training expectations. The positive social change that could result from these findings is the standardization of training that may help decrease restraint use and become the foundation of more respectful and caring practices in nursing homes.

The use of coercion in psychiatry involves clinical, legal, scientific, ethical and emotional considerations. This thesis represents an attempt to further increase our understanding of some empirical aspects of this phenomenon. Interviews with 202 involuntarily admitted psychiatric patients and 201 voluntarily admitted patients and 295 of their next of kins were performed and analysed together with data from records and assessments made by professionals. Data was collected during two different periods of time with a compulsory psychiatric care law reform in between. Experience of at least one coercive measure was more common amongst patients who had been committed during the most recent legislation. Otherwise there were no differences in patient experiences during the different laws. Subjective short-term outcome was associated with having a contact person at the ward and being subjectively treated well. There were no relationships between subjective and assessed outcome or between legal status, perceived coercion at admission and subjective or assessed improvement. The changed legislation had no clear effect on the attitudes of patients and next of kins towards coercion. A majority of patients were able to accurately answer the question whether they had been restrained by belt or not during a specific treatment episode. Nineteen of 115 patients reported they had been restrained by belt. Eleven of these cases were true positive and 8 cases were false positive. In conclusion, the main results were first that when it comes to issues related to psychiatric coercion there are typically considerable differences between how these are perceived and interpreted by the professional and by the patient, and second that efforts made to change the face of psychiatric coercion in the minds of patients as well as the public on part of public policymakers have had limited effects.

Every year 9000 children are estimated to die in traffic accidents in China. Fast motorization of the country in combination with low usage of child restraint system’s (CRS’s), are the two contributing factors to this alarming number. The vision of this thesis is to increase the usage of CRS’s in China, by understanding why the users are using the CRS and why the non-users are not using. The behavioural methodology Switch was used to investigate what positive behaviours could be copied and implemented in a larger scale to increase the usage. Interviews were performed with 30 users and 30 non-users in tier 1, tier 2, and tier 3 cities on the east coast of China. The main findings from the interviews showed that the reasons for not using was that the parents found the CRS complicated to install and to use, that it took too much space, that they did not know the benefits with a CRS and found it unnecessary and that they could not convince their children to sit in the CRS. Surprisingly most non-users already owned a CRS, but stopped using it. The users were using because they had experienced the CRS from abroad or got knowledge from other sources such as media or friends. Some parents were using because of a practicality issues such as the trouble to hold a heavy 3-year old child during a long trip. The behaviours chosen to represent the users for further work were learning from others, selection support, how to install, how to persist, and how to pay the knowledge of the CRS forward. The behaviour of the users was copied and implemented in a strategy consisting of the five parts above. The strategy is an interactive webpage with a close linkage to social networks to encourage sharing, and with a supporting poster- and bumper sticker campaign for spreading. The final product of the thesis work is a campaign including a fully working prototype of the webpage, which will be handed over to Volvo Cars for verification internally to make sure that the concept supports the different parts in a suitable and correct way before a public implementation. Material for poster and bumper stickers is also a part of the final delivery.

This paper is a study about outdoor education in pre- school. The main purpose is to look over if outdoor education in pre- school is a restraint or a resource. The study is based on two questionnaires, one to personnel in pre- school and one to parents who have children in pre- school. The study showed that outdoor education is mostly viewed to be a resource but there can be some problems in how to use it. Time, planning and knowledge were problems that were often mentioned by teachers. Parents often thought that outdoor education was important, but they didn’t choose pre- school because of the outdoor education orientation. It showed that location was more important. / Arbetet beskriver utomhuspedagogik i förskolan. Syftet med studien var att se om utomhuspedagogik i förskolan var ett tvång eller en tillgång. Studien är baserad på två enkäter, en till personal på förskolan och en till föräldrar som har barn på förskolan. Resultatet visade att utomhuspedagogik i förskolan oftast var en tillgång, men det fanns problem i hur man använde det. Tid, planering och kunskap var problem som ofta nämndes av lärarna. Föräldrar tyckte oftast att utomhuspedagogik var viktigt,  men de valde inte förskola på grund av utomhuspedagoik som inriktning, läget var viktigare.
