Proclaiming a prophecy empty of substance?: A pragmatist reconsideration of global governance

In 1995, the UN Commission on Global Governance published their “Our Global Neighbourhood” report and the academic journal “Global Governance: A Review of Multilateralism and International Organizations” was launched. Both events in retrospect play a significant role in the emergence of global governance thinking and practice in world politics. Despite inherent ambiguities, this idea since then gained massive traction and became both a modality and a heuristic of world politics. Advancing a pragmatist framework, we unpack global governance in terms of the beliefs which underline and guide it. These beliefs are important since they, as rules for action, define the scope of global governance as a theoretical and a political concept. Reconstructing these beliefs directly from the 1995 report, the article highlights the inherent conflations of normative and analytical commitments indicative of global governance. As a projection surface of all kinds, we believe such a reconsideration of global governance is important to (a) reveal the baselines of its thinking and practice, (b) indicate how its normative and analytical ambitions overlap and conflate, and (c) contribute to a more reflective discussion on the idea which explicitly considers its inherent normativity. At the same time, we hope to show the value of a pragmatist framework on beliefs for the study of world politics

Determination of measurement uncertainty by Monte Carlo simulation

Modern coordinate measurement machines (CMM) are universal tools to measure geometric features of complex three-dimensional workpieces. To use them as reliable means of quality control, the suitability of the device for the specific measurement task has to be proven. Therefore, the ISO 14253 standard requires, knowledge of the measurement uncertainty and, that it is in reasonable relation with the specified tolerances. Hence, the determination of the measurement uncertainty, which is a complex and also costly task, is of utmost importance. The measurement uncertainty is usually influenced by several contributions of various sources. Among those of the machine itself, e.g., guideway errors and the influence of the probe and styli play an important role. Furthermore, several properties of the workpiece, such as its form deviations and surface roughness, have to be considered. Also the environmental conditions, i.e., temperature and its gradients, pressure, relative humidity and others contribute to the overall measurement uncertainty. Currently, there are different approaches to determine task-specific measurement uncertainties. This work reports on recent advancements extending the well-established method of PTB's Virtual Coordinate Measuring Machine (VCMM) to suit present-day needs in industrial applications. The VCMM utilizes numerical simulations to determine the task-specific measurement uncertainty incorporating broad knowledge about the contributions of, e.g., the used CMM, the environment and the workpiece

A Neurological Outpatient Clinic for Patients With Post-COVID-19 Syndrome — A Report on the Clinical Presentations of the First 100 Patients

Background and Objectives: Neurological and psychiatric symptoms are frequent in patients with post-COVID-19 syndrome (PCS). Here, we report on the clinical presentation of the first 100 patients who presented to our PCS Neurology outpatient clinic ≥ 12 weeks after the acute infection with SARS-CoV-2. To date, PCS is only defined by temporal connection to SARS-CoV-2 infection. Identification of clinical phenotypes and subgroups of PCS is urgently needed. Design: We assessed clinical data of our first 100 ambulatory patients regarding clinical presentations; self-questionnaires focusing on daytime sleepiness, mood, and fatigue; and a screening assessment for detecting cognitive impairment. Results: A total of 89% of the patients presenting to the Neurology outpatient clinic had an initially mild course of COVID-19 and had not been hospitalized. The majority of the patients were female (67 vs. 33% male). The most frequent symptom reported was cognitive impairment (72%). There were 30% of patients who reported cognitive deficits and scored below 26 points on the Montreal Cognitive Assessment Scale. Fatigue (67%), headache (36%), and persisting hyposmia (36%) were also frequently reported; 5.5% of all patients showed signs of severe depression. Discussion: To our knowledge, this is the first report of patient data of a PCS Neurology outpatient clinic. Neurological sequelae also exist for more than 3 months after mainly mild SARS-CoV-2 acute infections. The reported symptoms are in accordance with recently published data of hospitalized patients

Superman = Persepolis = Naruto? Herausforderungen und Probleme der formalen und inhaltlichen Vielfalt von Comics und Comicforschung für die RVK

Das populäre Medium Comic hat in den vergangenen Jahren zunehmend Interesse als wissenschaftliches Forschungsobjekt und damit auch als bibliothekarisches Sammlungsgut auf sich gezogen. Bibliotheken stehen vor der Aufgabe, die Primärquellen und vor allem die wissenschaftliche Forschungsliteratur zu Comics inhaltlich zu erschließen und nach wie vor auch systematisch zu präsentieren. Bis vor kurzem fand man in der in Deutschland am weitesten verbreiteten Klassifikation, der im Selbstverständnis wissenschaftsnahen Regensburger Verbundklassifikation, nur Einzelstellen in einzelnen Fachsystematiken und einen größeren Bereich in der Japanologie für das Phänomen Manga. Dieser Zustand war nicht ausreichend für eine differenzierte Aufstellung in Bibliotheken mit entsprechenden Beständen und Schwerpunkten. Der hier präsentierte RVK-Baum für Comics und Comicforschung wird diesem Desiderat gerecht und bietet eine Möglichkeit, Comicbestände adäquat klassifikatorisch abzubilden.   In recent years the popular medium of comics has attracted increasing research interest and, consequently, comics have been recognized as objects for collection in libraries. Libraries face the task of classifying the primary sources and especially the scientific research literature on comics in order to present them systematically. Until recently, the most widely used academic library classification in Germany, the Regensburg Classification (RVK), provided only individual notations in some subject classifications and, additionally, a larger area on manga in the Japanese studies section. This situation was not sufficient for a differentiated shelving, or, respectively, classifying in libraries with correspondent resources and priorities. The paper presents a tree of RVK-notations for comics and comic research, which satisfies the desiderata and provides a way to map comic collections adequately to a classificatory schem

Tailored Palladium Catalysts for Selective Synthesis of Conjugated Enynes by Monocarbonylation of 1,3-Diynes

For the first time, the monoalkoxycarbonylation of easily available 1,3-diynes to give synthetically useful conjugated enynes has been realized. Key to success was the design and utilization of the new ligand 2,2′-bis(tert-butyl(pyridin-2-yl)phosphanyl)-1,1′-binaphthalene (Neolephos), which permits the palladium-catalyzed selective carbonylation under mild conditions, providing a general preparation of functionalized 1,3-enynes in good-to-high yields with excellent chemoselectivities. Synthetic applications that showcase the possibilities of this novel methodology include an efficient one-pot synthesis of 4-aryl-4H-pyrans as well as the rapid construction of various heterocyclic, bicyclic, and polycyclic compounds. © 2020 The Authors.

Large eddy simulation of a low-pressure turbine cascade with turbulent end wall boundary layers

We present results of implicit large eddy simulation (LES) and different Reynolds-averaged Navier-Stokes (RANS) models of the MTU 161 low pressure turbine at an exit Reynolds number of 90,000 and exit Mach number of 0.6. The LES results are based on a high order discontinuous Galerkin method and the RANS is computed using a classical finite-volume approach. The paper discusses the steps taken to create realistic inflow boundary conditions in terms of end wall boundary layer thickness and free stream turbulence intensity. This is achieved by tailoring the input distribution of total pressure and temperature, Reynolds stresses and turbulent length scale to a Fourier series based synthetic turbulence generator. With this procedure, excellent agreement with the experiment can be achieved in terms of blade loading at midspan and wake total pressure losses at midspan and over the channel height. Based on the validated setup, we focus on the discussion of secondary flow structures emerging due to the interaction of the incoming boundary layer and the turbine blade and compare the LES to two commonly used RANS models. Since we are able to create consistent setups for both LES and RANS, all discrepancies can be directly attributed to physical modelling problems. We show that both a linear eddy viscosity model and a differential Reynolds stress model coupled with a state-of-the-art correlation-based transition model fail, in this case, to predict the separation induced transition process around midspan. Moreover, their prediction of secondary flow losses leaves room for improvement as shown by a detailed discussion turbulence kinetic energy and anisotropy fields.Comment: invited submission to Flow, Turbulence and Combustion Special Issue: 13th ERCOFTAC Workshop on Direct and Large Eddy Simulation - DLES1

Current Developments of Clinical Sequencing and the Clinical Utility of Polygenic Risk Scores in Inflammatory Diseases

In this mini-review, we highlight selected research by the Deutsche Forschungsgemeinschaft (DFG) Cluster of Excellence "Precision Medicine in Chronic Inflammation" focusing on clinical sequencing and the clinical utility of polygenic risk scores as well as its implication on precision medicine in the field of the inflammatory diseases inflammatory bowel disease, atopic dermatitis and coronary artery disease. Additionally, we highlight current developments and discuss challenges to be faced in the future. Exemplary, we point to residual challenges in detecting disease-relevant variants resulting from difficulties in the interpretation of candidate variants and their potential interactions. While polygenic risk scores represent promising tools for the stratification of patient groups, currently, polygenic risk scores are not accurate enough for clinical setting. Precision medicine, incorporating additional data from genomics, transcriptomics and proteomics experiments, may enable the identification of distinct disease pathogeneses. In the future, data-intensive biomedical innovation will hopefully lead to improved patient stratification for personalized medicine
