Este trabalho analisa a recepção de Georg Büchner (1813-1837) por Bertolt Brecht (1898-1956) enfocando a sua fase criativa inicial. Especificamente analisa-se a abordagem da recepção do drama Woyzeck em Tambores na Noite e da narrativa Lenz, de Büchner, em Baal de Brecht. As duas obras de Büchner, como a maior parte de seus trabalhos, foram publicadas postumamente: Lenz, em 1837, e Woyzeck, em 1878. Esta última estreou em 1913. A obra do autor, quase desconhecida em sua época, encontrou ressonância no Realismo e no Naturalismo, mas o auge da recepção se deu na virada do século XIX para o XX, com a Modernidade e os expressionistas. A presente análise investiga a repercussão de Woyzeck e de Lenz como formas específicas da recepção de Büchner por Brecht. Os dois escritores são importantes por refletirem posições críticas quanto à política e quanto ao ideário de suas épocas, na Alemanha. Brecht usou ambas as obras de Büchner como inspiração para pôr em evidência a posição do indivíduo frente a uma época em decadência, que se caracteriza ademais pela política autoritária na Alemanha, bem como pela falta de liberdade individual. A análise baseia-se na pesquisa hermenêutica de Hans Gadamer e nas premissas acerca da estética da recepção de Hans Robert Jauss. Partindo da estética da recepção, os dramas Tambores na Noite e Baal são examinados quanto à sua intertextualidade com o drama Woyzeck e a narrativa Lenz de Büchner, com auxílio de reflexões elaboradas por Broich e Pfister, num método que permite analisar as relações históricas e textuais entre obras literárias. Neste trabalho, procuramos estabelecer uma relação intertextual direta entre Woyzeck e Tambores na Noite e também entre Lenz e Baal, algo negligenciado na pesquisa literária até o presente momento. / This work analyzes the reception of Georg Büchner (1813-1837) by Bertolt Brecht (1898-1956), focusing Brechts initial creative phase. In particular, the reception of the drama Woyzeck in Drums in the Night and of the novel Lenz, from Büchner, in Baal, from Brecht, is analyzed. Both works of Büchner, as is also the case for the majority of his remaining texts, were published posthumously: Lenz, in 1837, and Woyzeck, in 1878; the drama had its premiere only in November 1913. His works, close to unknown at his time, obtained some resonance in realism and in naturalism but the peak of the reception of his works occurred only in the beginning of the XXth century, with modernism and the expressionists. The present analysis investigates the impact of Woyzeck and Lenz and the specific form of Brechts reception of Büchner. Both these authors are important since they reflect critical positions within the political and ideological scenarios of their times, in Germany. Brecht used both works from Büchner as inspiration to put in evidence the position of the individual in a time of decadence, which, moreover was characterized by an authoritarian and repressive politics in Germany, as well as the lack of individual freedom. This analysis is based in the literary hermeneutics of Hans Gadamer, and the premises of the reader-response criticism of Hans Robert Jauss. The dramas Drums in the Night and Baal are examined taking into account the intertextuality with the drama Woyzeck and narrative Lenz of Büchner, with the help of reflections elaborated by Broich and Pfister, a method which allows to clarify the historic and textual relations of literary works. In this thesis we attempt to establish a direct intertextual relation between the dramas Woyzeck and Drums in the Night and also of Lenz and Baal, which had not been previously identified in literary research up to now.

La vision de nuit des pilotes d’hélicoptère est artificiellement assistée par un dispositif de vision bas niveau de lumière constitué d’un intensificateur de lumière (IL) couplé à une caméra numérique d’une part, et d’une caméra infrarouge (IR) d’autre part. L’objectif de cette thèse est d’améliorer ce dispositif en ciblant les défauts afin de les corriger.Une première partie consiste à réduire le bruit dont souffrent les images IL. Cela nécessite d’évaluer la nature du bruit qui corrompt ces images. Pour cela, une méthode d’estimation automatique du bruit est mise en place. L’estimation repose sur la détection non paramétrique de zones homogènes de l’image. Les statistiques du bruit peuvent être alors être estimées à partir de ces régions homogènes à l’aide d’une méthode d’estimation robuste de la fonction de niveau de bruit par minimisation l1.Grâce à l’estimation du bruit, les images IL peuvent alors débruitées. Nous avons pour cela développé dans la seconde partie un algorithme de débruitage d’images qui associe les moyennes non locales aux méthodes variationnelles en effectuant une régularisation adaptative pondérée parune attache aux données non locale. Une adaptation au débruitage de séquences d’images permet ensuite de tenir compte de la redondance d’information apportée par le flux vidéo, en garantissant stabilité temporelle et préservation des structures fines.Enfin, dans la troisième partie les informations issues des capteurs optique et infrarouge sont recalées dans un même référentiel. Nous proposons pour cela un critère de recalage multimodal basé sur l’alignement des contours des images. Combiné à une résolution par montée de gradient et à un schéma temporel, l’approche proposée permet de recaler de façon robuste les deuxmodalités, en vue d’une ultérieure fusion. / Night vision for helicopter pilots is artificially enhanced by a night vision system. It consists in a light intensifier (LI) coupled with a numerical camera, and an infrared camera. The goal of this thesis is to improve this device by analyzing the defaults in order to correct them.The first part consists in reducing the noise level on the LI images. This requires to evaluate the nature of the noise corrupting these images, so an automatic noise estimation method has been developed. The estimation is based on a non parametric detection of homogeneous areas.Then the noise statistics are estimated using these homogeneous regions by performing a robust l`1 estimation of the noise level function.The LI images can then be denoised using the noise estimation. We have developed in the second part a denoising algorithm that combines the non local means with variational methods by applying an adaptive regularization weighted by a non local data fidelity term. Then this algorithm is adapted to video denoising using the redundancy provided by the sequences, hence guaranteeing temporel stability and preservation of the fine structures.Finally, in the third part data from the optical and infrared sensors are registered. We propose an edge based multimodal registration metric. Combined with a gradient ascent resolution and a temporel scheme, the proposed method allows robust registration of the two modalities for later fusion.

The study of macroecology not only identifies patterns in the distribution and abundance of species at large spatial and temporal scales, it also gives insight into the processes underlying those patterns. The contribution of this work is not limited to helping develop the field of ecology per se, but also provides important insights into the understanding of large scale processes like climate change, the spread of introduced species, pest control and how increasing pressure from anthropogenic activities threatens biodiversity and ecosystem services. During the first decade following its formal inception, most of the progress in macroecology was made through studies of animal species, and research into plant species continues to lag far behind. This thesis contributes to the study of the macroecology of plant species by examining some selected macroecological patterns that have been studied only for animal species and by including an important issue that might have significant effects on diverse macroecological patterns, namely anthropogenic activities. The second and third chapters of the thesis address the generalised individuals-area relationship (GIAR) and the patch individuals-area relationship (PIAR), two macroecological relationships not previously explored for plant species. I show for the first time the existence of negative GIARs at the intraspecific and interspecific levels in plant species, similar to those documented for animal species. Unlike animal species, I did not find a broadly consistent intraspecific PIAR in plant species; more than half of the tested species showed negative PIARs. The resource concentration hypothesis may help explain those positive PIARs that were observed. The fourth chapter considers the effect of past human activities on current patterns of plant species richness at a landscape scale. Using a detailed database on the historical anthropogenic activities for Cornwall, U.K., I examine the relationship between species richness and the area covered by each historical land-use at two different spatial resolutions (10km x 10km and 2km x 2km). I find that at the 10km x10km scale human activities carried out since the 17th and 19th centuries explain an important proportion of the variation in current plant species richness. In contrast, a model at 2km x 2km scale with upland woods and the total land area of a grid cell explain only 5% of the variation. The fifth and sixth chapters focus on how artificial light at night (ALAN), which has increasingly come to attention as a significant anthropogenic pressure on species, is interacting with the distributions of plant species. In the fourth chapter, I consider the plant family Cactaceae to determine the proportion of the global distribution ranges of species that is being influenced by ALAN, and how this changes with the size of these distribution ranges and over a 21-year period (1992 to 2012). I found that >80% of cacti species are experiencing ALAN somewhere in their distribution range, and that there is a significant upward trend in ALAN in the ranges of the vast majority of species. For the sixth chapter, I consider similar issues for the threatened plant species of Britain, exploiting new remote sensing imagery of nighttime lighting at a very fine spatial resolution (c.340x340m2). Only 8% of Britain is free of artificial light at night and in consequence a high number of threatened plant species have a high proportion of their range under some influence of ALAN.

The current study set out to shed light on the performances that 2016 US presidential candidates used during their interventions on the late-night comedy shows. Following the methodologies ofCritical Discourse Analysis, the aim of the thesis was to uncover and, therefore, analyze, the type of discourses that candidates used in the shows and how they combined them. There was establisheda special focus on the rhetorical styles used by each candidate, as well as the emotional content ofthe discourses, unexpected situations and comedy performances, with the aim to find the elements which lead to virality. This study reveals the rhetorical strategies used by politicians through ananalysis of the political and personal discourses they used in late-nigh comedy shows. According tothe results, the political discourse is most prevalent during the interview than the personal, which isused to start conversations and evoke personalized emotions. The study provides insights upon the elements found in politicians’ discourses on the late-night circuit that lead to achieve virality on social media.

Titel: Röntgensjuksköterskans upplevelse av att arbeta med externa granskare under jourtid Syfte: Att undersöka hur röntgensjuksköterskan upplever arbetet med externa granskare under jourtid. Material och metod: Sex stycken röntgensjuksköterskor från två olika sjukhus i mellansverige intervjuades under perioden januari till mars 2017. Inklusionskriterierna för studien var minst två års erfarenhet av yrket samt minst ett års erfarenhet av att arbeta med externa granskare under jourtid. Tillstånd från verksamhetschefer och samtycke från informanterna erhölls innan studien startade. Data samlades in genom en kvalitativ metod med semistrukturerade intervjuer bestående av öppna frågor. Den insamlade datan analyserades med kvalitativ innehållsanalys enligt Graneheim & Lundman. Intervjuerna transkriberades och lästes igenom flera gånger. Därefter identifierades meningsbärande enheter och dessa kondenserades till koder. Genom koderna kunde kategorier och subkategorier identifieras. Resultat: I resultatet framkom fyra kategorier; Teleradiologi – tekniska aspekter, externa granskare jämfört med radiolog på plats, kommunikation och röntgensjuksköterskans kompetenser och egenskaper med tillhörande subkategorier. Konklusion: Informanterna upplever att det tar längre tid att kommunicera med externa granskare (EG) i jämförelse med att ha en radiolog på plats som kan ge svar direkt när röntgensjuksköterskan (RSS) är i behov av vägledning och snabba svar. I kommunikationen upplevs det också finnas språkbarriärer samt bristande kunskap, speciellt hos de sekreterare som tar emot samtal hos EG. Detta leder till frustration och blir ofta ett hinder i akuta situationer då RSS vill prata med en radiolog direkt. Under jourtid upplever RSS att denne får ta ett ökat ansvar samtidigt som förmågan att ta egna initiativ och beslut måste finnas. RSS upplever ingen förändring av bildkvalitén på de bilder som skickas i arbetet med EG. Informanterna upplevde i helhet att arbetet med EG fungerar bra och tillfredsställande under förutsättningarna att tekniken fungerar som den ska samtidigt som arbetsflödet inte ökar för mycket.

Despite extensive research into shift work, workers working under rotating shift conditions are still plagued by the effects of the desynchronisation resulting from working against their natural circadian rhythms. Additionally, modern industries are shifting towards tasks requiring greater cognitive demand with less manual labour incorporated into the tasks. Research into operator based tasks, and hence those of a sedentary cognitive base both during day and night shifts, has been focusing on the effectiveness of the standard rest/break schedule. Research indicating that the standard rest break schedule is often ineffective in eliminating operator discomfort and performance deterioration, with these affects argued to be more pronounced during a night shift schedule. Therefore current research set out to investigate alternative rest break schedules, incorporating a short bout of physical activity and stretching exercises which are proposed to enhance performance and subjective mood, while eliminating operator discomfort for sedentary based cognitive tasks. Three conditions were tested during a three day habituation shift cycle within a laboratory, incorporating two night shift groups (control and experimental) and a control day shift group. Twelve subjects made up each group, with the two night shift groups completing the shift schedule together. The control groups followed a typical 8 hour shift schedule while the experimental group performed a booster break (exercise and stretches) activity for 7.5 minutes every hour during the night shift schedule. Over the course of the shift, subjects completed a battery of six tests providing data on physiological measurements (heart rate and temperature), performance criteria (reaction time responses, memory and neurobiological) and subjective measures. Responses obtained for all the different parameters measured indicated a strong circadian influence for the majority of the variables, indicating the course of natural down regulation within physiological and performance criteria over the night shift. The booster break significantly improved reaction time performance, subjective ratings and resulted in a high sustainable activity level. Day shift comparisons indicating that within subjective measures and reaction time performance, the booster break resulted in similar responses to those of the day shift workers, while the control night shift groups reported significantly lowers results. Additionally, the booster break had positive influences during the circadian nadir, significantly improving parameters of performance and subjective ratings of sleepiness. The results of this study indicating which variables are strong predictors and indicators of the oscillations in performance and subjective ratings due to the circadian changes. The booster break interventions had positive effects on subjective ratings and reaction time performance, while also being argued to decrease the burden placed on the cardiac system as a result of increased sympathetic tone during the night shift, while additionally resulting in similar responses to those of day shift workers. Further studies are required, however, to provide conclusive evidence particularly within a working situation over a longer shift schedule.

The emergence of astrocasting on the Internet offered an opportunity to study the creation of a Social Media site, and determine the influence of the participants’ perception of this leisure activity and their motivation for it. The Night Skies Network was examined under a Social Media theoretical framework. The motivation for astrocasting was studied using the Self-Determination Theory of Motivation, and its perception as a leisure activity using the Serious Leisure Perspective. The methodology used included a focus group that provided a qualitative perspective, and an on-line questionnaire using the Serious Leisure Inventory and Measure and the Leisure Motivation Scale for quantitative data. The results showed that the Night Skies Network did meet the requirements for a Social Media site, that the participants considered astrocasting as a serious leisure activity, and that they were intrinsically motivated towards it, with a strong emphasis on the Intrinsic Motivation to Know.

Au vignoble, des nuits froides peuvent se produire pendant la floraison et en particulier au moment de la méiose ovulaire dans les fleurs. La vigne est particulièrement vulnérable puisque la méiose ovulaire se produit lors de la transition du métabolisme de la plante d'un état hétérotrophe à un état autotrophe. Bien que la feuille soit l'organe photosynthétique principal, la jeune inflorescence de vigne possède un statut particulier et participe activement à l'effort reproducteur en exportant la majorité du carbone qu'elle assimile, permettant ainsi le développement des feuilles. Par conséquent, le métabolisme carboné de l'inflorescence lors du développement reproducteur peut être impliqué dans le futur rendement. Chez la vigne, le phénomène de coulure, propre à chaque cépage, peut engendrer des pertes de rendement importantes lorsque la plante est exposée à un stress. Le Pinot noir (PN) est considéré comme un cépage relativement « résistant » à la coulure alors que le taux d'abscission chez le Gewurztraminer (GW) augmente considérablement lors de conditions climatiques défavorables. Chez le PN, l'inflorescence effectue une photosynthèse inférieure et une respiration de nuit supérieure à celle de la feuille. L'activité et la régulation des deux photosystèmes sont très différentes entre ces deux organes lors des premiers stades de développement et les activités des deux photosystèmes sont supérieures au niveau de l'inflorescence. Néanmoins, la protection de la chaîne photosynthétique contre l'excès d'énergie est plus efficace dans la feuille. Contrairement à la feuille, l'activité photosynthétique de l'inflorescence évolue au cours de son développement. En effet, l'activité de la chaîne photosynthétique ainsi que la photosynthèse nette diminuent progressivement au cours de la floraison et le flux cyclique des électrons se met en place pour être finalement supérieur à celui de la feuille. L'activation de ce flux peut alors permettre une synthèse accrue d'ATP, une protection de la chaîne photosynthétique contre les dommages provoqués par un excès d'énergie ou encore la réparation des photosystèmes. Lorsque la nuit froide survient lors de la méiose ovulaire, le métabolisme carboné de l'inflorescence de PN est différemment modifié selon l'intensité du stress. Ainsi, après une nuit à 4°C, la modification de l'activité photosynthétique de l'inflorescence est due à des limitations de nature non-stomatique alors qu'après une nuit à 0°C, cette modification est due à des limitations de nature stomatique. Une nuit à -3°C altère profondément l'activité photosynthétique de l'inflorescence. Ces nuits froides induisent également une accumulation de glucides. Lors du développement floral en conditions optimales, le PN et le GW présentent une activité photosynthétique et un métabolisme carboné différents. La régulation des flux linéaire et cyclique des électrons est également différente. Ce dernier semble avoir une fonction différente chez ces deux cépages avec notamment une possible implication dans la réparation du PSII et/ou dans une synthèse d'ATP accrue à la fin du processus de floraison chez le PN. La chaîne photosynthétique du GW semble mieux protégée ce qui peut expliquer le rendement supérieur de ce cépage en conditions optimales. Néanmoins, l'exposition à une nuit froide entraine des modifications différentes de l'activité de l'inflorescence chez ces cépages avec une perturbation plus importante chez le GW. En effet, chez ce cépage, seule la photosynthèse nette est perturbée suite à la nuit froide alors que chez le PN, les processus de photosynthèse et de respiration sont modifiés. L'activité de la chaîne photosynthétique ainsi que l'activité métabolique de l'inflorescence de GW est également davantage affectée. De manière intéressante, nos résultats suggèrent que ces différentes perturbations de l'activité de l'inflorescence sont dues à des régulations différentes. / In the vineyard, cold night can occur during flowering and particularly at time of female meiosis in flowers. In grapevine, stress vulnerability is enhanced because female meiosis occurs when the whole plant physiology is switching its carbon nutrition from mobilization of wood reserves to photosynthesis in the leaves. Nevertheless, although leaf is the major photosynthetic organ, in grapevine, the young inflorescence has a particular status and takes part in the reproductive effort by exporting the majority of assimilated carbon, allowing in particular the leaves development. Consequently, the inflorescence metabolism during this phase can ultimately determines yield. In grapevine, coulure phenomenon, differing according to the cultivar, can generate important yield losses when a stress occurs. Pinot noir (PN) is considered as a cultivar relatively “resistant” to coulure phenomenon whereas Gewurztraminer (GW) abscission rate considerably increases under environmental stress.In PN, inflorescence performs a lower photosynthesis and a higher dark respiration than leaves. Functioning and regulation of PSI and PSII are very different between inflorescence and leaf during the first developmental stages and activities of these photosystems are higher in the inflorescence. Nevertheless, the photosynthetic chain against excess energy is more efficient in the leaf. Contrary to the leaf, the inflorescence photosynthetic activity evolves during the floral development. Indeed, photosynthetic chain activity and net photosynthesis progressively decrease and the cyclic electron flow appears and is higher than in leaf. This activation could provide ATP, protection against photodamage or repair of the photosystems.When cold night occurs at the female meiosis stage, carbohydrate metabolism of the PN inflorescence is differently modified according to the intensity of the cold stress. At 4°C, photosynthesis in the inflorescence is impaired through non-stomatal limitations, whereas at 0°C it is affected through stomatal limitations. A freezing night (-3°C) severely deregulates photosynthesis in the inflorescence. Cold nights also induce accumulation of sugars.Comparing PN and GW, different photosynthetic activity and carbohydrate metabolism have been showed during the floral development under optimal conditions. Regulations of the linear and cyclic electron flow are also different and the cyclic electron flow seems to have a different aim with particularly an implication in the recovery of PSII and ATP synthesis at the end of the flowering process in PN. GW could have higher protection of the photosynthetic chain and consequently gets a higher yield under optimal conditions. Nevertheless, chilling night impacts differently the activity of the inflorescences of both cultivars with higher modification in GW inflorescence. Indeed, in this cultivar, only the net photosynthesis is altered whereas in PN, both net photosynthesis and respiration processes are modified. The photosynthetic chain activity and metabolical activity of the inflorescence are also more affected by the cold night in GW. Interestingly, our results suggest that the different fluctuation of the inflorescence activities as response to the chilled night is due to different regulations.
