Guerre et exil chez Louis-Ferdinand Céline

O nosso estudo incide, primordialmente, sobre as polémicas de carácter político e consequentes acusações de que Louis-Ferdinand Céline foi – e continua a ser – alvo. Tais aspectos conduzem-nos a questionar, com alguma veemência e perplexidade, as razões da sua fuga através da Alemanha, bem como as relações que estabeleceu com os Nazis durante a segunda guerra mundial. Num primeiro momento, elaborámos uma contextualização de cariz temporal e factual, tentando perceber – quiçá explicar -, o sentido das posições assumidas por Céline aquando da composição dos seus pamphlets, marcada por uma reivindicação violenta do seu antisemitismo e que surge, omnipresente, sob forma de cartas, entrevistas e outros escritos. Contudo, a essência do nosso trabalho consistiu numa análise detalhada das diferentes etapas dos anos de exílio do escritor, primeiro numa Alemanha devastada pela guerra, onde se refugia a partir de 17 de Junho de 1944 e mais tarde, na Dinamarca (1945-1951), de onde terá de responder às acusações de traição que lhe são dirigidas pela justiça francesa, antes de um regresso sem glória, a França, e de uma reabilitação tardia e titubeante. Os escritos que constituem o corpus do nosso trabalho traduzem, de modo inequívoco, a experiência amarga e cruel dos anos de exílio e da lembrança feita de dor e ódio, que o escritor sentiu profundamente, como um espinho na própria carne. Apesar do caminho tortuoso, que lhe confere uma aura de escritor “maldito”, Céline permanece, ainda hoje, como um dos maiores génios da literatura francesa do século XX.

Soil function and biodiversity: regional variations and climate changes

Embora o objetivo principal da proteção internacional dos solos seja proteger tanto as funções quanto a estrutura do solo, a atual abordagem trata principalmente da proteção ao nível estrutural. Há uma carência de estudos que contemplem a ligação das funções do solo com os níveis da comunidade. Além disso, é ainda desconhecido se as variáveis ambientais (ex: tipos de solo, condições climáticas) atuam nas funções do solo da mesma maneira que influenciam sua estrutura biológica. Ademais, as alterações climáticas poderão ter sozinhas ou combinadas com os poluentes, um grande efeito nos ecossistemas terrestres. O presente trabalho propõe estudar as funções e a estrutura biológica do solo quando impactados devido a estresse tóxico (poluição por Cu) e/ou alterações a fatores como a temperatura e abundância de organismos, de maneira a simular possíveis variações regionais ou climáticas. Para alcançar os objetivos principais 3 experiências utilizando diferentes densidades de E. crypticus e 2 gerações foram feitas (Capítulos II e III). Duas experiências com mesocosmos (SMS) decorreram durante 3 meses sob uma gama de diversas temperaturas (10 – 29°C), que representam temperaturas médias para Portugal e Dinamarca (Capítulos IV e V). Duas experiências de campo também foram realizadas com intuito de validar os SMSs (Capítulo VI). Resultados demonstraram que os efeitos do Cu na reprodução dos enquitraídeos dependem da densidade inicial de organismos, especialmente na 2ª geração. Entretanto, nos SMSs expostos a Cu, a densidade inicial é menos importante nos resultados finais. O aumento da temperatura alterou majoritariamente a fase inicial de crescimento populacional. Em períodos mais longos, a abundância estabilizou tornando-se menos influenciada pelas temperaturas. Períodos longos de exposição reforçaram os efeitos da temperatura, como por ex: diversas espécies foram similarmente afetadas a 29 ou 26°C quando expostas durante 28 ou 61 dias respectivamente. De forma geral, o Cu reduziu a abundância da maioria das espécies ao longo do tempo, com poucas exceções. Os resultados da decomposição da matéria orgânica (MO) e atividade alimentar associaram-se com a abundância de organismos em baixas temperaturas (10-23°C). Entretanto, com o aumento das temperaturas (19-29°C), este comportamento não foi claro e a abundância de espécies e atividade alimentar diminuíram enquanto a decomposição da MO aumentou. Além disso, os resultados observados nos SMSs foram confirmados no campo. Mais especificamente, alterações ocorreram na fase de crescimento (correspondente à Primavera) e a exposição ao Cu diminuiu os efeitos da temperatura. Metodologias mais complexas (ex: mais gerações e experiências com múltiplas espécies) apresentam muitos benefícios, mas também proporcionam respostas mais complexas, as quais exigem um maior “peso” de evidências para serem comprovadas.

Competitive Intelligence : Aufbau einer Informationsbasis und Entscheidungssystematik zur Definition strategischer Zielmärkte

Im Rahmen der Globalisierung und des daraus resultierenden Wettbewerbs ist es für ein Unternehmen von zentraler Bedeutung, Wissen über die Wettbewerbssituation zu erhalten. Nicht nur zur Erschließung neuer Märkte, sondern auch zur Sicherung der Unternehmensexistenz ist eine Wettbewerbsanalyse unabdingbar. Konkurrenz- bzw. Wettbewerbsforschung wird überwiegend als „Competitive Intelligence“ bezeichnet. In diesem Sinne beschäftigt sich die vorliegende Bachelorarbeit mit einem Bereich von Competitive Intelligence. Nach der theoretischen Einführung in das Thema werden die Ergebnisse von neun Experteninterviews sowie einer schriftlichen Expertenbefragung innerhalb des Unternehmens erläutert. Die Experteninterviews und -befragungen zum Thema Competitive Intelligence dienten zur Entwicklung eines neuen Wettbewerbsanalysekonzeptes. Die Experteninterviews zeigten, dass in dem Unternehmen kein einheitliches Wettbewerbsanalysesystem existiert und Analysen lediglich ab hoc getätigt werden. Zusätzlich wird ein Länderranking vorgestellt, das zur Analyse europäischer Länder für das Unternehmen entwickelt wurde. Die Ergebnisse zeigten, dass Dänemark und Italien für eine Ausweitung der Exportgeschäfte bedeutend sind. Der neu entwickelte Mitbewerberbewertungsbogen wurde auf Grundlage dieser Ergebnisse für Dänemark und Italien getestet.

Temporal and Georaphical Variations in Grass Pollen Seasons in Areas of Western Europe: an Analysis of Season dates at Sites of the European Pollen Information System.

Geographical and temporal variations in the start dates of grass pollen seasons are described for selected sites of the European Pollen Information Service. Daily average grass pollen counts are derived from Network sites in Finland, the Netherlands, Denmark, United Kingdom, Austria, Italy and Spain, giving a broad longitudinal transect over Western Europe. The study is part of a larger project that also examines annual and regional variations in the severity, timing of the peak and duration of the grass pollen seasons. For several sites, data are available for over twenty years enabling long term trends to be discerned. The analyses show notable contrasts in the progression of the seasons annually with differing lag times occurring between southern and northern sites in various years depending on the weather conditions. The patterns identified provide some insight into geographical differences and temporal trends in the incidence of pollinosis. The paper discusses the main difficulties involved in this type of analysis and notes possibilities for using data from the European Pollen Information service to construct pan European predictive models for pollen seasons.

Do Urban Canyons Influence Street Level Grass Pollen Concentrations

In epidemiological studies, outdoor exposure to pollen is typically estimated using rooftop monitoring station data, whilst exposure overwhelmingly occurs at street level. In this study the relationship between street level and roof level grass pollen concentrations was investigated for city centre street canyon environments in Aarhus, Denmark, and London, UK, during the grass pollen seasons of 2010 and 2011 respectively. For the period mid-day to late evening, street level concentrations in both cities tended to be lower than roof-level concentrations, though this difference was found to be statistically significant only in London. The ratio of street/roof level concentrations was compared with temperature, relative humidity, wind speed and direction, and solar radiation. Results indicated that the concentration ratio responds to wind direction with respect to relative canyon orientation and local source distribution. In the London study, an increase in relative humidity was linked to a significant decrease in street/roof level concentration ratio, and a possible causative mechanism involving moisture mediated pollen grain buoyancy is proposed. Relationships with the other weather variables were not found to be significant in either location. These results suggest a tendency for monitoring station data to overestimate exposure in the canyon environment.

Personal Exposure to Grass Pollen: Relating Inhaled Dose to Background Concentration

Background Very few studies on human exposure to allergenic pollen have been conducted using direct methods, with background concentrations measured at city center monitoring stations typically taken as a proxy for exposure despite the inhomogeneous nature of atmospheric pollen concentrations. A 2003 World Health Organization report highlighted the need for an improved understanding of the relation between monitoring station data and actual exposure. Objective To investigate the relation between grass pollen dose and background concentrations measured at a monitoring station, to assess the fidelity of monitoring station data as a qualitative proxy for dose, and to evaluate the ratio of dose rate to background concentration. Methods Grass pollen dose data were collected in Aarhus, Denmark, in an area where grass pollen sources were prevalent, using Nasal Air Samplers. Sample collection lasted for approximately 25 to 30 minutes and was performed at 2-hour intervals from noon to midevening under moderate exercise by 2 individuals. Results A median ratio of dose rate to background concentration of 0.018 was recorded, with higher ratio values frequently occurring at 12 to 2 pm, the time of day when grass species likely to be present in the area are expected to flower. From 4 to 8 pm, dose rate and background concentration data were found to be strongly and significantly correlated (rs = 0.81). Averaged dose rate and background concentration data showed opposing temporal trends. Conclusion Where local emissions are not a factor, background concentration data constitute a good quantitative proxy for inhaled dose. The present ratio of dose rate to background concentration may aid the study of dose–response relations.

Defining Spatial and Temporal Hydromorphological Sampling Strategies for the Leigh Brook River Site

Detailed surveys of depth and velocity are undertaken to describe hydro-ecological status of rivers. Fieldwork for these surveys is time consuming and expensive. This paper aims to describe the methodology applied in order to determine the most suitable depth sampling strategy for effective field data collection and river representation in time and space at the Leigh Brook river site, Worcester, UK. The accuracy of three different sampling strategies for predicting depth at non-measured points has been compared and the mesohabitats that better characterise depth changes due to variations in discharge have been identified. The results show that depth changes due to discharge change are mainly located at shallow and deep glide mesohabitat types. The analysis for the comparison of sampling strategies indicates that grid sampling strategies give better results than regular transects. Since the results also show that higher errors in predictions are obtained in the deepest areas, higher sampling densities should be applied in these locations.

CNN Interactive just got more interactive

Interactive gallery installation which playfully re-contextualised online news feeds from CNN’s website with a soundtrack of found music in order to comment on an online environment where 'serious' news and trivial 'infotainment' often occupy the same space. ‘CNN Interactive just got more interactive’ aimed to investigate the balance between information and ‘info-tainment’ on the web. It demonstrated how the authority and presence of global news corporations online could be playfully subverted by enabling the audience to add a variety of emotively titled soundtracks to the monolithic CNN Interactive website. The project also explored how a work could exist dually as website and gallery installation. ‘CNN interactive’ contributes to the taxonomy of new media art as a new form of contemporary art. One of the first examples in the world of a gallery installation using live Internet data, it is also one of the first attempts in a new media art context to address how individuals respond to and comprehend the changed nature of the news as an immediate phenomenon as relayed by network communications systems. 'CNN interactive’ continues Craighead and Thomson’s research into how live digital networked information can be re-purposed as artistic material within gallery installation contexts but with specific reference to online-international news events, rather than arbitrary data sources (see e-poltergeist, output 1). ‘CNN Interactive’ was commissioned by Tate Britain for the exhibition ‘Art and Money Online’. This was the first gallery exhibition in Tate Britain featuring work that utilised and explored new media as an artistic area, and the first work commissioned by the Tate to operate simultaneously as an online gallery artwork. Selected reviews and citations include ‘Digital Art’ by Christiane Paul, 2003; ‘Internet Art: The Online Clash of Culture and Commerce’ by Julian Stallabrass. (2002); ‘Thomson & Craighead’ by Lisa Le Feuvre for Katalog Journal of Photography and Video, Denmark. All work is developed jointly and equally between Craighead and her collaborator, Jon Thomson, (Slade).

Supporting the learning and networking experiences of doctoral students

This study explores the impact of a Graduate Virtual Research Environment (GVRE) on the learning and networking experiences of research students. The GVRE was established to support and enhance research skills and employability training across a university. It provides an extensive range of resources including video reflections based on the experiences of students and staff; GVRE members are encouraged to comment and engage in discussions on these resources. Our work is framed using social theories of learning and the role of communities in the support and development of research students. In particular, we are interested in exploring the challenges involved in developing communities and networks for students whose main focus is their individual research. The GVRE was made available to over 600 students and in this research we explore its impact on the experiences of research students. In particular, we investigate four questions: (a) what impact does the students use of the GVRE have on the development of their research skills; (b) what impact does membership of the GVRE have on the networks and communities of research students; (c) how do research students view the relationships between their research skills training programme, their individual research and the GVRE; and (d) how do research students currently use social media. We use an interpretivist approach and our data sources include site statistics, responses to a questionnaire and also feedback from a focus group. Our findings indicate that networking remains an issue and students suggested approaches to facilitating this using the GVRE: (1) A clearer pathway from skills need identification to skills acquisition; (2) Rewards for activities around networking - possibly through credit on the training scheme; (3) Activities that would involve research directly. Feedback on the GVRE indicated that it is valued by research students as it facilitates the development of their research skills. In terms of marketing the GVRE to research students important factors identified were: the ease of access to the site, the overview it gives of the PhD process; and the value of the site to students around the defining moments of their studies when the students felt they needed additional advice and guidance.

Networked learning ten years on: the rise of the virtual graduate school

The aim of this paper is to reflect on how conceptions of networked learning have changed, particularly in relation to educational practices and uses of technology, that can nurture new ideas of networked learning to sustain multiple and diverse communities of practice in institutional settings. Our work is framed using two theoretical frameworks: Giddens's (1984) structuration theory and Callon & Latour's (1981) Actor Network Theory as critiqued by Fox (2005) in relation to networked learning. We use these frameworks to analyse and critique ideas of networked learning embodied in both cases. We investigate three questions: (a) the role of individual agency in the development of networked learning; (b) the impact of technological developments on approaches to supporting students within institutional infrastructures; and (c) designing networked learning to incorporate Web 2.0 practices that sustain multiple communities and foster engagement with knowledge in new ways. We use an interpretivist approach by drawing on experiential knowledge of the Masters programme in Networked Collaborative Learning and the decision making process of designing the virtual graduate schools. At this early stage, we have limited empirical data related to the student experience of networked learning in current and earlier projects. Our findings indicate that the use of two different theoretical frameworks provided an essential tool in illuminating, situating and informing the process of designing networked learning that involves supporting multiple and diverse communities of practice in institutional settings. These theoretical frameworks have also helped us to analyze our existing projects as case studies and to problematize and begin to understand the challenges we face in facilitating the participation of research students in networked learning communities of practice and the barriers to that participation. We have also found that this process of theorizing has given us a way of reconceptualizing communities of practice within research settings that have the potential to lead to new ideas of networked learning.
