Periodic auroral events at the high-latitude convection reversal in the 16 MLT region

Combined optical and radar observations of two breakup-like auroral events near the polar cap boundary, within 74–76° MLAT and 1210 – 1240 UT (roughly 1540 – 1610 MLT) on 9 Jan. 1989 are reported. A two-component structure of the auroral phenomenon is indicated, with a local intensification of the pre-existing arc as well as a separate, tailward moving discrete auroral event on the poleward side of the background aurora, close to the reversal between well-defined zones of sunward and tailward ion flows. The all-sky TV observations do not indicate a connection between the two components, which also show different optical spectral composition. The 16 MLT background arc is located on sunward convecting field lines, as opposed to the 12–14 MLT auroral emission observed on this day. Although the magnetospheric plasma source (s) of the 16 MLT events are not easily identified from these ground-based data alone, it is suggested that the lower and higher latitude components, may map to the plasma sheet boundary layer and along open field lines to the magnetopause boundary, respectively. The events occur at the time of enhancements of westward ionospheric ion flow and corresponding eastward electrojet current south of 74° MLAT. Thus, they seem to be very significant events, involving periodic (10 min period), tailward moving filaments of field-aligned current/discrete auroral emission at the 16 MLT polar cap boundary.

Orgulho e preconceito: a visão de um vitoriano acerca de Portugal e dos portugueses

As narrativas bélicas de viagem do séc. XIX, no âmbito da Guerra Civil Portuguesa (1828-1834) são particularmente ricas enquanto fonte e memória histórica de acontecimentos importantes da História de Portugal. Mas além do seu potencial historiográfico, tais escritos são também o espelho da idiossincrasia – vitoriana – do autor reflectida na forma como transforma, constrói, julga ou interpreta a realidade do país que visita, bem como a maneira de ser do seu povo.

Pediatric emergencies admitted in the resuscitation room of a swiss university hospital.

OBJECTIVES: Pediatric resuscitation is an intense, stressful, and challenging process. The aim of this study was to review the life-threatening pediatric (LTP) emergencies admitted in a Swiss university hospital with regards to patients' demographics, reason for admission, diagnosis, treatment, significant events, critical incidents, and outcomes. METHODS: A retrospective observational cohort study of prospectively collected data was conducted, including all LTP emergencies admitted over a period of 2 years in the resuscitation room (RR). Variables, including indication for transfer, mode of prehospital transportation, diagnosis, and time spent in RR, were recorded. RESULTS: Of the 60,939 pediatric emergencies treated in our university hospital over 2 years, a total of 277 LTP emergencies (0.46%) were admitted in the RR. They included 160 boys and 117 girls, aged 6 days to 15.95 years (mean, 6.69 years; median, 5.06). A medical problem was identified in 55.9% (n = 155) of the children. Of the 122 children treated for a surgical problem, 35 (28.3%) went directly from the RR to the operating room. Hemodynamic instability was noted in 19.5% of all LTP emergencies, of which 1.1% benefited from O negative transfusion. Admission to the intensive care unit was necessary for 61.6% of the children transferred from another hospital. The average time spent in the RR was 46 minutes. The overall mortality rate was 7.2%. CONCLUSIONS: The LTP emergencies accounted for a small proportion of all pediatric emergencies. They were more medical than surgical cases and resuscitation measures because of hemodynamic instability were the most frequent treatment.

Collection of tracheal aspirate: safety and microbiological concordance between two techniques

Objective: To evaluate the safety of the performance of the traditional and protected collection techniques of tracheal aspirate and to identify qualitative and quantitative agreement of the results of microbiological cultures between the techniques. Method: Clinical, prospective, comparative, single-blind research. The sample was composed of 54 patients of >18 years of age, undergoing invasive mechanical ventilation for a period of ≥48 hours and with suspected Ventilator Associated Pneumonia. The two techniques were implemented in the same patient, one immediately after the other, with an order of random execution, according to randomization by specialized software. Results: No significant events occurred oxygen desaturation, hemodynamic instability or tracheobronchial hemorrhage (p<0.05) and, although there were differences in some strains, there was qualitative and quantitative agreement between the techniques (p<0.001). Conclusion: Utilization of the protected technique provided no advantage over the traditional and execution of both techniques was safe for the patient.

Cultura, identitat i diversitat: projecte de creació d'un centre d'experimentació cultural i artística

Quin hauria de ser el paper de les pràctiques artístiques i la cultura contemporània a la societat? I les institucions artístiques, quin rol haurien d’assolir? Aquest treball final de màster és una indagació entorn els fets més significatius al llarg de la història del món occidental pel que fa a la cultura que s’ha desenvolupat al marge dels poders. Una anàlisi de les relacions que s’estableixen entre aquests diversos àmbits, on es planteja un projecte que compleix les característiques de ser un laboratori per a les pràctiques artístiques contemporànies i la seva recerca. Partint, a més a més, de la base teòrica de la historia cultural que ens porta fins on som ara i com a conformadora de les identitats

Building a creative city brand through an international mega-event : Case: Helsinki World Design Capital 2012

In order to grow, cities are increasingly competing for attention, jobs, investments, visitors, residents and significant events. Cities need to come up with creative solutions to keep up with the competition; they ought to become creative cities. Attracting talented and diverse inhabitants is a key factor in developing a creative city, which on is characterized by openness, tolerance, vibrancy and diversity. Along the need for renewed city images city brand building has become popular. Helsinki is the World Design Capital 2012 (WDC 2012) and this mega-event presents a meaningful opportunity for the city to broadcast itself globally. The purpose of this study is to evaluate how Helsinki brands itself as a creative city through an international mega-event. The sub-aims are to: 1) Map the factors behind the creative city and their relation to the city of Helsinki, 2) Describe the city branding process, 3) Evaluate the role of the Helsinki World Design Capital 2012 mega-event in Helsinki’s creative city brand building. First, the theory discusses the concept of the creative city that has gained growing attention during the past decade. Then, the city branding process is described and the benefits of hosting a mega-event are presented. Finally, co-branding a city and a mega-event in order to generate maximum benefit from the mega-event, is reviewed. This is a qualitative research for which data was collected through three face-to-face interviews, the World Design Capital 2012 bid, Helsinki’s economic development strategy, a consulting firm’s research report on the case city and web-pages. The research reveals that Helsinki has shown interest in the creative city discussion. The terminology around the concept is however approached carefully. Helsinki fits many of the creative city characteristics and recognizes its flaws for which improvement strategies have been planned. Bottlenecks keeping the city from promoting a more open mind were mainly revealed in its organizational structures. Helsinki has no official brand strategy; nonetheless pressure to develop one is present. The World Design Capital 2012 mega-event is seen as a meaningful stepping board to strengthen Helsinki’s identity and image, and start thinking about a city brand. The brand strategies of the mega-event support the values and virtues of the city itself, which enables benefits of co-branding introduces in the theory part. Helsinki has no official brand and doesn’t call itself a creative city, however this study shows signs of the city taking steps towards building a creative city brand with the help of the Helsinki World Design Capital 2012 mega-event.

Teamwork and leadership : competitive youth soccer as a context for positive youth development

The purpose of this study was to examine processes and interactions that characterized positive developmental experiences in sport. A highly competitive and reputable U-17 girls' soccer team was chosen for the study through purposeful sampling, providing an information rich case from which data could be derived (Patton, 2002). Seventeen players and three coaches participated in this study. Based on an ethnographic methodology data were collected via observations and both informal and formal semi-structured interviews. Tlie data were coded according to the three procedures outlined by Seidel and Kelle (1995): a) noticing relevant phenomena, b) collecting examples of those phenomena, and c) analyzing those phenomena in order to find commonalities, differences, patterns and structures. Significant events and underlying themes were recounted chronologically through a collection of vignettes, aimed to provide a contextual lens for the reader. Results revolved around two prominent themes: Teamwork and leadership. These were closely related concepts that required players to demonstrate a wide range of developmental skills for the team to move collectively towards their end goal. Furthermore, teamwork and leadership experiences took both desirable and undesirable forms. For example, at the beginning of the season competition existed amongst the players at the expense of teamwork and leadership. As the season progressed the pursuit of a shared goal allowed the players to view each other as collaborators and teamwork and leadership skills became increasingly evident. At times, however, success on the field was prioritized above maintaining relationships off the field, requiring the coaches to intervene and re-establish equilibrium.

A la recherche d’événements clés susceptibles d’expliquer le passage à l’acte dans le parcours de vie d’hommes uxoricides

Les différentes recherches portant sur les homicides conjugaux, et plus spécialement des uxoricides, plus documentés parce que plus fréquents, apportent de nombreuses informations pertinentes concernant le contexte entourant l'homicide, la relation entre les conjoints et son évolution et même, parfois, sur l’enfance de l’homme qui a posé un tel geste sur sa conjointe ou ex-conjointe. Toutefois, des incohérences ont été relevées dans les écrits sur le sujet faisant qu’il est difficile d’identifier la dynamique qui conduit des hommes à tuer leur conjointe. Le déroulement de la vie des hommes ayant enlevé la vie de leur conjointe, c’est-à-dire les événements qu’ils ont vécus tout au cours de leur vie et qui ont pris un sens particulier pour eux, nous est apparue une avenue qui, à notre connaissance, n’aurait pas été étudiée. Il a dès lors été convenu que l’objectif principal de ce mémoire de maîtrise en criminologie consisterait à explorer s’il est possible d’identifier, dans la vie d’un échantillon d’hommes qui ont tué leur conjointe, un enchaînement d’événements qui pourrait contribuer à la compréhension de la dynamique conduisant à l’homicide conjugal. Plus précisément, il s’agissait d’identifier les perceptions qu’ont ces hommes des différents événements qu’ils considèrent comme ayant été marquants dans leur vie et les réactions qu’ont successivement produites ces perceptions. Le devis de cette étude est qualitatif. Dix hommes incarcérés forment l’échantillon. Tous ont été reconnus coupables du meurtre de leur conjointe ou ex-conjointe. Suite aux entrevues semi-structurées de type rétrospectif et thématique, une reconstitution des lignes de vie inspirée de la théorie de Agnew (2006) ainsi qu’une analyse thématique des récits recueillis ont été effectuées. Bien que les événements de la vie de chacun des hommes leur soient particuliers, il ressort néanmoins une structure commune aux lignes de vie. Cette structure est marquée d’un événement ou de conditions de vie marquants se rapportant à l’enfance, d’un événement porteur d’une remise en question survenue plus tard et d’un événement déclencheur conduisant au meurtre. L’événement porteur d’une remise en question paraît occuper une place centrale dans la vie des hommes participant à notre étude. Cet événement porteur d’une remise en question vient modifier les comportements et attitudes de l’homme manifestés subséquemment. Ainsi, à la lumière des résultats de cette recherche, il apparaît que l’ensemble du développement de la vie des hommes uxoricides, et plus spécialement les événements qu’ils identifient comme étant marquants, leur enchaînement et, surtout, leur façon de percevoir ces événements et d’y réagir doivent être pris en compte dans l’étude de la trajectoire qui a finalement abouti au passage à l’acte homicidaire. Autre fait à considérer, plusieurs des hommes interviewés ont mentionné qu’ils sentaient qu’un événement de la sorte se préparait dans leur vie. Ceci suggère une certaine prévisibilité de l’acte qui pourrait être perceptible dans le récit que font les hommes de leur vie et de leur perception d’eux en relation avec les éléments qu’ils identifient comme ayant été marquants pour eux au cours de celle-ci. Il reste toutefois beaucoup à faire dans cette découverte d’un outil de prévention de l’uxoricide.

Ce ne sont que des corps ; suivi de L'idéal de l'androgynie dans le réservoir des sens de Nelly Kaplan

Ce mémoire en recherche-création explore l’hybridation identitaire et le désir d’échapper aux attentes normatives. Dans le récit Ce ne sont que des corps, deux étrangers attendent le train en se racontant, en alternance, les événements qui ont marqué les derniers mois de leur vie. Emmanuel, âgé de vingt-cinq ans, s’éprend de Michelle, une femme de tête quinquagénaire rencontrée dans un bar. Cette femme rêve de réaliser certains fantasmes et Emmanuel accepte de se plier au jeu jusqu’à ce que les choses s’enveniment. Quant à Alex, jeune femme dans la vingtaine, elle quitte son village natal pour étudier à Montréal et succombe au charme de Gabriel, un aspirant musicien pour qui elle est prête à tout abandonner. Chacun des personnages de ce roman brouille les identités sexuées et sexuelles. Pour ce qui est de l’essai, il explore la manière dont Nelly Kaplan manipule le sexe et le gender de ses protagonistes pour postuler une « poétique de l’androgynie » dans certaines nouvelles du recueil Le réservoir des sens. L’essai mobilise les ressources des études consacrées à l’ironie, à la poétique surréaliste, au gender ainsi qu’à l’intertextualité pour mettre en évidence la façon dont l’auteure brouille les identités sexuées et sexuelles.

Studies on some nonlinear schrodinger type equations describing pulse propagation through optical fibers

The discovery of the soliton is considered to be one of the most significant events of the twentieth century. The term soliton refers to special kinds of waves that can propagate undistorted over long distances and remain unaffected even after collision with each other. Solitons have been studied extensively in many fields of physics. In the context of optical fibers, solitons are not only of fundamental interest but also have potential applications in the field of optical fiber communications. This thesis is devoted to the theoretical study of soliton pulse propagation through single mode optical fibers.
