The power of Trump-Speak : populist crisis narratives and ontological security

For most observers, the election of Donald Trump as the 45th president of the United States (US) came as a shock. This has been widely recast as the culmination of the American public’s long-standing dissatisfaction with the political elite and deep-seated frustrations with broader socio-economic conditions. We argue that the Trump campaign’s success also stemmed from its effective use of an emotionally charged, anti-establishment crisis narrative. With insights from political psychology, we examine the socio-linguistic mechanisms that underlie the effectiveness of ‘Trump-speak’ through both quantitative and qualitative content analysis of Trump’s communications toolkit during the 2016 US presidential election campaign. We show that his leadership legitimation claims rest significantly upon ‘crisis talk’ that puts his audience in a loss frame with nothing to lose and explain why ‘crisis talk’ impacts on political behaviour. As we demonstrate, the crisis stories that political agents tell simultaneously instil ontological insecurity among the American public and serve to transform their anxiety into confidence that the narrator’s policy agendas are the route back to ‘normality’. Through these rhetorical mechanisms, the Trump campaign manipulated individuals’ ontological (in)security as a tool in the politics of reassurance at the broader, societal level

Simultaneous Mass Spectrometry-Based Apolipoprotein Profiling and Apolipoprotein E Phenotyping in Patients with ASCVD and Mild Cognitive Impairment

Apolipoprotein E (apoE) occurs on the majority of plasma lipoproteins and plays a major role in the lipid metabolism in the periphery and in the central nervous system. ApoE is a polymorphic protein with three common isoforms, apoE2, apoE3 and apoE4, derived from respective alleles '2, '3 and '4. The aim of this study was to develop a sample pretreatment protocol combined with rapid mass spectrometry (MS)-based assay for simultaneous apolipoprotein profiling and apoE phenotype identification. This assay was validated in 481 samples from patients with stable atherosclerotic cardiovascular disease (ASCVD) and applied to study association with mild cognitive impairment (MCI) in the LIFE Adult study, including overall 690 study subjects. Simultaneous quantification of 8–12 major apolipoproteins including apoA-I, apoB-100 and apoE could be performed within 6.5 min. Phenotyping determined with the developed MS assay had good agreement with the genotyping by real-time fluorescence PCR (97.5%). ApoE2 isoform was associated with the highest total apoE concentration compared to apoE3 and apoE4 (p < 0.001). In the subgroup of diabetic atherosclerotic cardiovascular disease (ASCVD) patients, apoE2 isoform was related to higher apoC-I levels (apoE2 vs. apoE3, p < 0.05), while in the subgroup of ASCVD patients under statin therapy apoE2 was related to lower apoB-100 levels (apoE2 vs. apoE3/apoE4, p < 0.05). A significant difference in apoE concentration observed between mild cognitive impairment (MCI) subjects and controls was confirmed for each apoE phenotype. In conclusion, this study provides evidence for the successful implementation of an MS-based apoE phenotyping assay, which can be used to assess phenotype effects on plasma lipid and apolipoprotein levels

Genome-wide meta-analysis of phytosterols reveals five novel loci and a detrimental effect on coronary atherosclerosis

Correction: Volume13, Issue1 Article Number1122 DOI 10.1038/s41467-022-28863-y Published FEB 25 2022Phytosterol serum concentrations are under tight genetic control. The relationship between phytosterols and coronary artery disease (CAD) is controversially discussed. We perform a genome-wide meta-analysis of 32 phytosterol traits reflecting resorption, cholesterol synthesis and esterification in six studies with up to 9758 subjects and detect ten independent genomewide significant SNPs at seven genomic loci. We confirm previously established associations at ABCG5/8 and ABO and demonstrate an extended locus heterogeneity at ABCG5/8 with different functional mechanisms. New loci comprise HMGCR, NPC1L1, PNLIPRP2, SCARB1 and APOE. Based on these results, we perform Mendelian Randomization analyses (MR) revealing a risk-increasing causal relationship of sitosterol serum concentrations and CAD, which is partly mediated by cholesterol. Here we report that phytosterols are polygenic traits. MR add evidence of both, direct and indirect causal effects of sitosterol on CAD.Peer reviewe

Evaluating model outputs using integrated global speleothem records of climate change since the last glacial

Although quantitative isotopic data from speleothems has been used to evaluate isotope-enabled model simulations, currently no consensus exists regarding the most appropriate methodology through which to achieve this. A number of modelling groups will be running isotope-enabled palaeoclimate simulations in the framework of the Coupled Model Intercomparison Project Phase 6, so it is timely to evaluate different approaches to use the speleothem data for data-model comparisons. Here, we illustrate this using 456 globally-distributed speleothem δ18O records from an updated version of the Speleothem Isotopes Synthesis and Analysis (SISAL) database and palaeoclimate simulations generated using the ECHAM5-wiso isotope-enabled atmospheric circulation model. We show that the SISAL records reproduce the first-order spatial patterns of isotopic variability in the modern day, strongly supporting the application of this dataset for evaluating model-derived isotope variability into the past. However, the discontinuous nature of many speleothem records complicates procuring large numbers of records if data-model comparisons are made using the traditional approach of comparing anomalies between a control period and a given palaeoclimate experiment. To circumvent this issue, we illustrate techniques through which the absolute isotopic values during any time period could be used for model evaluation. Specifically, we show that speleothem isotope records allow an assessment of a model’s ability to simulate spatial isotopic trends. Our analyses provide a protocol for using speleothem isotopic data for model evaluation, including screening the observations to take into account the impact of speleothem mineralogy on 18O values, the optimum period for the modern observational baseline, and the selection of an appropriate time-window for creating means of the isotope data for palaeo time slices

The 2020 UV emitter roadmap

Solid state UV emitters have many advantages over conventional UV sources. The (Al,In,Ga)N material system is best suited to produce LEDs and laser diodes from 400 nm down to 210 nm—due to its large and tuneable direct band gap, n- and p-doping capability up to the largest bandgap material AlN and a growth and fabrication technology compatible with the current visible InGaN-based LED production. However AlGaN based UV-emitters still suffer from numerous challenges compared to their visible counterparts that become most obvious by consideration of their light output power, operation voltage and long term stability. Most of these challenges are related to the large bandgap of the materials. However, the development since the first realization of UV electroluminescence in the 1970s shows that an improvement in understanding and technology allows the performance of UV emitters to be pushed far beyond the current state. One example is the very recent realization of edge emitting laser diodes emitting in the UVC at 271.8 nm and in the UVB spectral range at 298 nm. This roadmap summarizes the current state of the art for the most important aspects of UV emitters, their challenges and provides an outlook for future developments

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder

La légitimation discursive de l'Union Européenne : analyse lexicométrique de l'usage du signe « Europe/Europa » dans les programmes électoraux des élections européennes des partis politiques allemand, français et britannique entre 1979 et 2004

Ma thèse présente une analyse du signifiant Europe dans trois corpus allemand, français, britannique. Chaque corpus contient les programmes électoraux européens des partis politiques nationaux qui ont obtenu au moins une fois un siège au Parlement Européen. La période commence aux premières élections européennes en 1979 et se termine avec les élections européennes de 2004.Une analyse lexicométrique du signifiant Europe dans les trois langues révèle de nouvelles perspectives pour la compréhension linguistique de la notion d'Europe dans ces champs politico-discursifs. Elle permet de tirer des conclusions sur les problèmes de communication au niveau européen, sur l'objectif politique de l'Union Européenne et la légitimation du pouvoir de l'UE. Selon notre hypothèse de recherche, une telle légitimation se fonde sur une conception imaginaire de l'identité européenne commune aux différents peuples. Même si le pouvoir politique peut considérer qu'il est légitimé par une telle conception, l'analyse révèle des différences importantes entre les conceptions imaginaires circulant dans les trois champs discursifs comparés.L'analyse lexicométrique est exploitée sur le plan quantitatif mais aussi au niveau qualitatif. A l'échelle quantitative, l'index, les spécificités d'Europe, ses quasi-synonymes et les cooccurrences d'Europe sont analysés et interprétés. L'approche qualitative du contexte du segment thématique répété Europe est...' conduit à des conclusions supplémentaires. L'analyse de ce segment définitoire cherche à rendre visible, dans une démarche pragmatique, le contenu impliqué des différents énoncés. Cela conduit à figurer l'horizon sémantique au sein duquel le signe Europe apparaît. Les positionnements de la notion d'Europe et les argumentations liées à l'expression linguistique dans les trois différents corpus sont comparés dans cette phase de la recherche afin de mettre en évidence l'horizon discursif dans lequel apparaît la notion d'Europe.My PhD thesis analysis the signifier Europe in three corpora composed of German, French and British texts. Every corpus contains elections manifestos from national political parties that were represented in the European Parliament at least once with one a seat. The study starts with the first European elections 1979 and ends with the European elections of 2004.An analysis with the help of textual statistical measurements reveals new perspectives on the language comprehension of the notion Europe in the three different fields of political discourses. It allows conclusions about communication problems on a European level, about the political objectives of the European Union and about the legitimation of its political power. According to the research hypothesis the legitimation of the political power of the European Union is based on an imagined conception of a common European identity. Even if the political actors claim that they are legitimized by such an identity the study reveals something different. It shows some substantial differences between the imagined conceptions circulating within the three studied fields of political discourses.The textual corpora are explored with quantitative measurements and also with qualitative methods of text analysis. The frequency, the specific use of Europe and its quasi-synonyms, as the collocation of Europe are measured quantitatively. Additional conclusions were drawn from the qualitative analysis of the thematic word unit Europe is'. The analysis of this word unit is based on a pragmatic understanding of sense and tries to bring to evidence the implied content of the different utterances. In doing so, the semantic horizon of the sign Europe can be represented. During this research phase argumentations linked to the linguistic expression Europe are explored in order to analyse the discursive horizon in which the notion is used in the different discourses

Towards a post-material prosperity? An analysis of legitimising narratives in German crisis discourses from 1973 and 2008

In this paper I compare narratives representing the first Petrol Crises (1973) and the recent Financial Crisis (2008) in the German press. With a specific focus on the mantra-like phrase ‘growth generates prosperity’ I propose a mixed methods approach to large text corpora. The narratives unveiled with quantitative methods are interpreted on the text level applying topos-analysis and Laclau and Mouffe’s post-structuralist theory of hegemony
