Notions of Conflict and 'New' Citizens' Inclusion:Post-Cosmopolitan Contestations in Germany

This chapter argues that there is a gap between symbolic exclusion from the national community when it comes to the inclusion of new German citizens of Turkish or Kurdish background, and a broad claim to be a cosmopolitan society, at large. While focusing on narratives of minority key political activists in Berlin, and analysing individual stories on the background of contemporary populist xenophobic debates and hate crime of the 1990s, the chapter illustrates both, individual success and vulnerability due to institutionalised forms of anti- Muslim and anti-Turks segments in Germany.

Evaluation of the matabolic response of osteosarcoma cells to conventional and new anticancer drugs by NMR metabolomics

The main scope of this work was to evaluate the metabolic effects of anticancer agents (three conventional and one new) in osteosarcoma (OS) cells and osteoblasts, by measuring alterations in the metabolic profile of cells by nuclear magnetic resonance (NMR) spectroscopy metabolomics. Chapter 1 gives a theoretical framework of this work, beginning with the main metabolic characteristics that globally describe cancer as well as the families and mechanisms of action of drugs used in chemotherapy. The drugs used nowadays to treat OS are also presented, together with the Palladium(II) complex with spermine, Pd2Spm, potentially active against cancer. Then, the global strategy for cell metabolomics is explained and the state of the art of metabolomic studies that analyze the effect of anticancer agents in cells is presented. In Chapter 2, the fundamentals of the analytical techniques used in this work, namely for biological assays, NMR spectroscopy and multivariate and statistical analysis of the results are described. A detailed description of the experimental procedures adopted throughout this work is given in Chapter 3. The biological and analytical reproducibility of the metabolic profile of MG-63 cells by high resolution magic angle spinning (HRMAS) NMR is evaluated in Chapter 4. The metabolic impact of several factors (cellular integrity, spinning rate, temperature, time and acquisition parameters) on the 1H HRMAS NMR spectral profile and quality is analysed, enabling the definition of the best acquisition parameters for further experiments. The metabolic consequences of increasing number of passages in MG-63 cells as well as the duration of storage are also investigated. Chapter 5 describes the metabolic impact of drugs conventionally used in OS chemotherapy, through NMR metabolomics studies of lysed cells and aqueous extracts analysis. The results show that MG-63 cells treated with cisplatin (cDDP) undergo a strong up-regulation of lipid contents, alterations in phospholipid constituents (choline compounds) and biomarkers of DNA degradation, all associated with cell death by apoptosis. Cells exposed to doxorubicin (DOX) or methotrexate (MTX) showed much slighter metabolic changes, without any relevant alteration in lipid contents. However, metabolic changes associated with altered Krebs cycle, oxidative stress and nucleotides metabolism were detected and were tentatively interpreted at the light of the known mechanisms of action of these drugs. The metabolic impact of the exposure of MG-63 cells and osteoblasts to cDDP and the Pd2Spm complex is described in Chapter 6. Results show that, despite the ability of the two agents to bind DNA, the metabolic consequences that arise from exposure to them are distinct, namely in what concerns to variation in lipid contents (absent for Pd2Spm). Apoptosis detection assays showed that, differently from what was seen for MG-63 cells treated with cDDP, the decreased number of living cells upon exposure to Pd2Spm was not due to cell death by apoptosis or necrosis. Moreover, the latter agent induces more marked alterations in osteoblasts than in cancer cells, while the opposite seemed to occur upon cDDP exposure. Nevertheless, the results from MG-63 cells exposure to combination regimens with cDDP- or Pd2Spm-based cocktails, described in Chapter 7, revealed that, in combination, the two agents induce similar metabolic responses, arising from synergy mechanisms between the tested drugs. Finally, the main conclusions of this thesis are summarized in Chapter 8, and future perspectives in the light of this work are presented.

Beyond Robotic Wastelands of Time: Abandoned Pedagogical Agents and New Pedalled Pedagogies

Chatbots, known as pedagogical agents in educational settings, have a long history of use, beginning with Alan Turing’s work. Since then online chatbots have become embedded into the fabric of technology. Yet understandings of these technologies are inchoate and often untheorised. Integration of chatbots into educational settings over the past five years suggests an increase in interest in the ways in which chatbots might be adopted and adapted for teaching and learning. This article draws on historical literature and theories that to date have largely been ignored in order to (re)contextualise two studies that used responsive evaluation to examine the use of pedagogical agents in education. Findings suggest that emotional interactions with pedagogical agents are intrinsic to a user’s sense of trust, and that truthfulness, personalisation and emotional engagement are vital when using pedagogical agents to enhance online learning. Such findings need to be considered in the light of ways in which notions of learning are being redefined in the academy and the extent to which new literacies and new technologies are being pedalled as pedagogies in ways that undermine what higher education is, is for, and what learning means.

Philosophies, traditional pedagogy, and new technologies: a report on a case study of EAP teachers' integration of technology into traditional practice

This chapter reports on a study of teachers in transition, developing their practice and their cognitions regarding the integration of learning technologies with traditional approaches to the teaching of English for Academic Purposes (EAP). Taking a case study approach, it examines developments in the practice of three teachers during and after a teacher education programme on the use of technology in the EAP classroom. This is a study of cognition, teaching philosophy, and the relationship between pedagogy, technology, and content, and how teachers situate these within their own practice. The setting is the rapidly changing UK higher education environment, where the speed of change is such that today's latest fashions and gadgets may well be yesterday's news tomorrow. Thus, this is not a tale of individual technologies or tools to make teachers' lives better. This is a story of people, of pedagogy's traditional values intersecting with technology, and the issues arising from this, alongside the evolution of strategies for dealing with these issues.

ESL Collections, University Libraries, and Internationalization

This research study examines the content, types of materials, locations, and library collection development policies concerning ESL (English as a second language) materials collections on university campuses in the United States and Canada. ESL learning materials are defined in this study as those materials supporting adult learners who are non-native speakers of English in a higher education setting. The purpose of this study is to describe the content and types of materials in these collections, to learn where these collections are typically housed on university campuses, to discover what collection development policies may inform the building of these collections, and to explore the potential significance of these collections for university libraries. The overriding question that informs this study is the following: Can involvement with ESL collections serve as a way for university libraries to participate in internationalization by supporting the language needs of international students?

A Scalability Study and New Algorithms for Large-Scale Many-Objective Optimization

Many real-world optimization problems contain multiple (often conflicting) goals to be optimized concurrently, commonly referred to as multi-objective problems (MOPs). Over the past few decades, a plethora of multi-objective algorithms have been proposed, often tested on MOPs possessing two or three objectives. Unfortunately, when tasked with solving MOPs with four or more objectives, referred to as many-objective problems (MaOPs), a large majority of optimizers experience significant performance degradation. The downfall of these optimizers is that simultaneously maintaining a well-spread set of solutions along with appropriate selection pressure to converge becomes difficult as the number of objectives increase. This difficulty is further compounded for large-scale MaOPs, i.e., MaOPs possessing large amounts of decision variables. In this thesis, we explore the challenges of many-objective optimization and propose three new promising algorithms designed to efficiently solve MaOPs. Experimental results demonstrate the proposed optimizers to perform very well, often outperforming state-of-the-art many-objective algorithms.

Cerebral edema and acute liver failure : pathophysiological mechanisms and new therapeutic approaches

L’encéphalopathie hépatique (EH) se développe chez les patients atteints d’une maladie du foie et se caractérise par de nombreuses anomalies neuropsychiatriques. L’insuffisance hépatique aiguë (IHA) se caractérise par une perte progressive de l’état de conscience, par une augmentation rapide de l’œdème cérébral et une augmentation de la pression intracrânienne entraînant une herniation cérébrale et la mort. Plusieurs facteurs sont responsables du développement de l’EH mais depuis une centaine d’années, l’hyperammonémie qui peut atteindre des concentrations de l’ordre de plusieurs millimolaires chez les patients atteints d’IHA aux stades de coma est considérée comme un facteur crucial dans la pathogenèse de l’EH. La présente thèse comprend 4 articles suggérant l’implication de nouveaux mécanismes pathogéniques dans le développement de l’EH et de l’œdème cérébral associés à l’IHA et tente d’expliquer l’effet thérapeutique de l’hypothermie et de la minocycline dans la prévention de l’EH et de l’œdème cérébral: 1. L’IHA induite par dévascularisation hépatique chez le rat se caractérise par une augmentation de la production de cytokines pro-inflammatoires cérébrales (IL-6, IL-1, TNF-). Cette observation constitue la première évidence directe que des mécanismes neuro-inflammatoires jouent une rôle dans la pathogenèse de l’EH et de l’œdème cérébral associés à l’IHA (Chapitre 2.1, articles 1 et 2). 2. L’activation de la microglie telle que mesurée par l’expression de marqueurs spécifiques (OX42, OX-6) coïncide avec le développement de l’encéphalopathie (stade coma) et de l’œdème cérébral et s’accompagne d’une production accrue de cytokines pro-inflammatoires cérébrales (Chapitre 2.1, article 1 et 2). 3. Un stress oxydatif/nitrosatif causé par une augmentation de l’expression de l’oxyde nitrique synthétase et une augmentation de la synthèse d’oxyde nitrique cérébral participe à la pathogénèse des complications neurologiques de l’IHA (Chapitre 2.3, articles 3 et 4). 4. Des traitements anti-inflammatoires tels que l’hypothermie et la minocycline peuvent constituer de nouvelles approches thérapeutiques chez les patients atteints d’IHA (Chapitre 2.1, article 1; Chapitre 2.2, article 2). 5. Les effets bénéfiques de l’hypothermie et de la minocycline sur les complications neurologiques de l’IHA expérimentale s’expliquent, en partie, par une diminution du stress oxydatif/nitrosatif (Chapitre 2.3, article 3; Chapitre 2.4, article 4).
