Bringing Europe Down to Earth
Why is it considered more European to vote in the affirmative of the Euro than it is to vote against it? Why is not possible to be a populist and a ?Good European? at the same time? What makes an illegal immigrant different from a tourist? These questions all concern the limits of what it means to be, act and think as Europeans in Europe. In the political process of bringing the nations and peoples of Europe together, Europe is imagined as a distinct community. The aim of this study is to analyse contemporary articulations of what makes Europe ?Europe? in the context of the political project of the EU. Elaborating on the correlation between articulations of a certain European identity and the politics of European integration, this thesis combines theories and perspectives of identity construction with theories that, more explicitly, deal with mechanisms of power and repression as immanent in any societal formation (i.e. discourse theory). By bringing Europe down to earth, the author highlights contradictions and tensions that are inherent in our perceptions of what makes Europe ?Europe?. In a first step, the study emphasises how knowledge of what makes Europe ?Europe? is reproduced in a ?constitutive split? between the positions of ?Europe? and ?the nation?. The analysis suggests that this relationship of mutual dependency further constrains the possibility of articulating alternative positions. Bringing Europe down to earth, in this perspective, means to underline the continuity between past attempts to imagine nation-states and current endeavours to articulate a certain European identity that knit together Europeans with a distinct notion of a European community. In a second step, the author focuses on contemporary labelling processes that separate ?us? (the Europeans) from them ?them?, the ?not-Europeans?. This dissertation includes analyses of domestic referenda on EU-related issues, the transformation of the EU into an area of freedom, security and justice and finally also the relation between Brussels and populism. The identity-making enterprise that takes place in the name of Europe is not merely about the making of spatial demarcations of where Europe ends or who is to become a European citizen and who is not. The question of what makes Europe ?Europe? is expressed also inside the territorial borders of the enlarged Union as manifest in a series of constitutive splits that separate between ?Good Europeans? and ?Bad Europeans?; between ?Good strangers? and ?Bad strangers?; between friends and foes. In his analysis of EU-elite rhetoric, the author infers that the European integration process is attached with a certain logic of irrevocability that trigger the development further, despite a lack of popular support. The project of bringing Europe down to earth encourages us to remove the question of Europe from the realm of historic necessity to the sphere of politics
Sweden's election is about more than the Sweden Democrats
Sweden will hold a general election on 9 September, alongside regional and municipal elections. Anders Hellström assesses the campaign so far, which has focused to a large extent on support for the anti-immigration Sweden Democrats. He suggests that the framing of the campaign around the policies of the Sweden Democrats, coupled with the other parties' lack of a positive, alternative vision for the country, goes some way toward explaining the current polling
Towards a full greenhouse gas budget at a clear-cut and stump harvested boreal forest site in Sweden
Malmbanan Diaries
This booklet is a report for a case study visit during four day field trip, a group of nine PhD students and their supervisors – all part of the National Research School for Architecture and Planning in the Urban Landscape, APULA – set out to explore what may be considered the outback of Western Europe’s conurbations, the transnational region of Kiruna -Narvik.Both “remote” and “resourceful”, “threatened” and “thriving” (equally relative notions), this region seemed to offer possibilities to reflect upon many of the current tendencies influencing contemporary planning practice and research
Comprehensive genetic and epigenetic analysis of sporadic meningioma for macro-mutations on 22q and micro-mutations within the NF2 locus
BACKGROUND: Meningiomas are the most common intracranial neoplasias, representing a clinically and histopathologically heterogeneous group of tumors. The neurofibromatosis type 2 (NF2) tumor suppressor is the only gene known to be frequently involved in early development of meningiomas. The objective of this study was to identify genetic and/or epigenetic factors contributing to the development of these tumors. A large set of sporadic meningiomas were analyzed for presence of 22q macro-mutations using array-CGH in order to identify tumors carrying gene dosage aberrations not encompassing NF2. The NF2 locus was also comprehensively studied for point mutations within coding and conserved non-coding sequences. Furthermore, CpG methylation within the NF2 promoter region was thoroughly analyzed. RESULTS: Monosomy 22 was the predominant finding, detected in 47% of meningiomas. Thirteen percent of the tumors contained interstitial/terminal deletions and gains, present singly or in combinations. We defined at least two minimal overlapping regions outside the NF2 locus that are small enough (~550 kb and ~250 kb) to allow analysis of a limited number of candidate genes. Bialleinactivationo the NF2 gne was detected in 36% of meningiomas. Among the monosomy 22 cases, no additional NF2 mutations could be identified in 35% (17 out of 49) of tumors. Furthermore, the majority of tumors (9 out of 12) with interstitial/terminal deletions did not have any detectable NF2 mutations. Methylation within the NF2 promoter region was only identified at a single CpG site in one tumor sample. CONCLUSION: We confirmed previous findings of pronounced differences in mutation frequency between different histopathological subtypes. There is a higher frequency of biallelic NF2 inactivation in fibroblastic (52%) compared to meningothelial (18%) tumors. The presence of macro-mutations on 22q also shows marked differences between fibroblastic (86%) and meningothelial (39%) subtypes. Thus, inactivation of NF2, often combined with the presence of macro-mutation on 22q, is likely not as important for the development of the meningothelial subtype, as opposed to the fibroblastic form. Analysis of 40 CpG sites distributed within 750 bp of the promoter region suggests that NF2 promoter methylation does not play a major role in meningioma development
Slow-release L-cysteine capsule prevents gastric mucosa exposure to carcinogenic acetaldehyde : results of a randomised single-blinded, cross-over study of Helicobacter-associated atrophic gastritis
Introduction: Helicobacter-induced atrophic gastritis with a hypochlorhydric milieu is a risk factor for gastric cancer. Microbes colonising acid-free stomach oxidise ethanol to acetaldehyde, a recognised group 1 carcinogen. Objective: To assess gastric production of acetaldehyde and its inert condensation product, non-toxic 2-methyl-1,3-thiazolidine-4-carboxylic acid (MTCA), after alcohol intake under treatment with slow-release L-cysteine or placebo. Methods: Seven patients with biopsy-confirmed atrophic gastritis, low serum pepsinogen and high gastrin-17 were studied in a cross-over single-blinded design. On separate days, patients randomly received 200 mg slow-release L-cysteine or placebo with intragastric instillation of 15% (0.3 g/kg) ethanol. After intake, gastric concentrations of ethanol, acetaldehyde, L-cysteine and MTCA were analysed. Results: Administration of L-cysteine increased MTCA (p <.0004) and decreased gastric acetaldehyde concentrations by 68% (p <.0001). The peak L-cysteine level was 7552 +/- 2687 mu mol/L at 40 min and peak MTCA level 196 +/- 98 mu mol/L at 80 min after intake. Gastric L-cysteine and MTCA concentrations were maintained for 3 h. The AUC for MTCA was 11-fold higher than acetaldehyde, indicating gastric first-pass metabolism of ethanol. With placebo, acetaldehyde remained elevated also at low ethanol concentrations representing 'non-alcoholic' beverages and food items. Conclusions: After gastric ethanol instillation, slow-release L-cysteine eliminates acetaldehyde to form inactive MTCA, which remains in gastric juice for up to 3 h. High acetaldehyde levels indicate a marked gastric first-pass metabolism of ethanol resulting in gastric accumulation of carcinogenic acetaldehyde. Local exposure of the gastric mucosa to acetaldehyde can be mitigated by slow-release L-cysteine capsules.Peer reviewe
The G Protein–Coupled Receptor Subset of the Chicken Genome
G protein–coupled receptors (GPCRs) are one of the largest families of proteins, and here we scan the recently sequenced chicken genome for GPCRs. We use a homology-based approach, utilizing comparisons with all human GPCRs, to detect and verify chicken GPCRs from translated genomic alignments and Genscan predictions. We present 557 manually curated sequences for GPCRs from the chicken genome, of which 455 were previously not annotated. More than 60% of the chicken Genscan gene predictions with a human ortholog needed curation, which drastically changed the average percentage identity between the human–chicken orthologous pairs (from 56.3% to 72.9%). Of the non-olfactory chicken GPCRs, 79% had a one-to-one orthologous relationship to a human GPCR. The Frizzled, Secretin, and subgroups of the Rhodopsin families have high proportions of orthologous pairs, although the percentage of amino acid identity varies. Other groups show large differences, such as the Adhesion family and GPCRs that bind exogenous ligands. The chicken has only three bitter Taste 2 receptors, and it also lacks an ortholog to human TAS1R2 (one of three GPCRs in the human genome in the Taste 1 receptor family [TAS1R]), implying that the chicken's ability and mode of detecting both bitter and sweet taste may differ from the human's. The chicken genome contains at least 229 olfactory receptors, and the majority of these (218) originate from a chicken-specific expansion. To our knowledge, this dataset of chicken GPCRs is the largest curated dataset from a single gene family from a non-mammalian vertebrate. Both the updated human GPCR dataset, as well the chicken GPCR dataset, are available for download
