Aufweichen, abbremsen, abschirmen – Wirtschaftsmetaphern zwischen politischer Abgrenzung und diskursiven Allgemeinplätzen [Forschungsdaten]
No full textOur study examines the use of metaphors in the German discourse regarding European monetary and fiscal policy. Though this policy area sparked considerable interest among linguists, so far there is a lacuna concerning interdisciplinary comparative studies that examine metaphorical expressions in regard to their divergent political use. This study addresses this desideratum by posing two explorative research questions: Which metaphors shape the political debate on European monetary and fiscal policy? And is there a relationship between the divergent use of metaphors and the political perspective they entail?
As a means to examine these questions, we develop an innovative methodological triangulation that combines qualitative, hermeneutic metaphorical analyses with quantitative, data-driven approaches of corpus linguistics. By analyzing the communication of eleven political actors during three formative debates on Eurozone policy, we isolate the most salient metaphors and compare their political usage.
Our results bring forth four types of metaphorical expression. These can be distinguished by their relative openness in concern to political perspective and their respective referent. Thereby, this study firstly provides an important guide to understanding the debate at hand; secondly, it sharpens the theoretical grasp in concern to the comprehension of political metaphors as a whole; and thirdly, we contribute a notable stake to the methodical study of metaphorical expressions in the field of applied linguistics.</p
Solvent-Controlled Quadruple Catenation of Giant Chiral [8+12] Salicylimine Cubes Driven by Weak Hydrogen Bonding [Data]
No full textA quadruply interlocked catenane has been formed from giant chiral [8+12] salicylimine cubes in a reaction that can be controlled by the reaction solvent. Single-crystal X-ray diffraction revealed hydrogen bonding to be a central driving force for the catenation. Furthermore, scrambling experiments with partially deuterated cages allowed mechanistic insights into the interlocking process
A role for retro-splenial cortex in the task-related P3 network [Research Data]
No full textObjective: The P3 is an event-related response observed in relation to task-relevant sensory events. Despite its ubiquitous presence, the neural generators of the P3 are controversial and not well identified. Methods: We compared source analysis of combined magneto- and electroencephalography (M/EEG) data with functional magnetic resonance imaging (fMRI) and simulation studies to better understand the sources of the P3 in an auditory oddball paradigm. Results: Our results suggest that the dominant source of the classical, postero-central P3 lies in the retro-splenial cortex of the ventral cingulate gyrus. A second P3 source in the anterior insular cortex contributes little to the postero-central maximum. Multiple other sources in the auditory, somatosensory, and anterior midcingulate cortex are active in an overlapping time window but can be functionally dissociated based on their activation time courses.
Conclusions: The retro-splenial cortex is a dominant source of the parietal P3 maximum in EEG. Significance: These results provide a new perspective for the interpretation of the extensive research based on the P3 response
Stable Carbon Isotope Signature of Methane Released from Phytoplankton [Research Data]
No full textAquatic ecosystems play an important role in global methane cycling and many field studies have reported methane supersaturation in the oxic surface mixed layer (SML) of the ocean and in the epilimnion of lakes. The origin of methane formed under oxic condition is hotly debated and several pathways have recently been offered to explain the ‘methane paradox’. In this context, stable isotope measurements have been applied to constrain methane sources in supersaturated oxygenated waters. Here we present stable carbon isotope signatures for six widespread marine phytoplankton species, three haptophyte algae and three cyanobacteria, incubated under laboratory conditions. The observed isotopic patterns implicate that methane formed by phytoplankton might be clearly distinguished from methane produced by methanogenic archaea. Comparing results from phytoplankton experiments with isotopic data from field measurements, suggests that algal and cyanobacterial populations may contribute substantially to methane formation observed in the SML of oceans and lakes
Palladium-Catalyzed Cyclization of a Pyryne Precursor to Higher Pyrenylenes [Data]
No full textBy palladium-catalyzed oligomerization reactions of pyrene-based o-trimethylsilyl triflates, larger cyclic pyrenylenes were formed with up to 10-membered rings as has been unambiguously characterized by SCXRD. Furthermore, the underlying reaction mechanism has been studied by quantum chemical calculations
Supplementary Material to: "Lu Xun on Display: Memory, Space and Media in the Making of World Literary Heritage or The Materiality of World Literary Heritage: Memory, Space and Media in the Making of Lu Xun"
No full textThis is the supplementary material to my doctoral thesis "Lu Xun on Display: Memory, Space and Media in the Making of World Literary Heritage or The Materiality of World Literary Heritage: Memory, Space and Media in the Making of Lu Xun". It contains the full set of images referred to in my thesis. The images cited in my thesis are organized in image clusters (IC). I have included a selected number of image clusters in the print and online version of the thesis. When the image cluster is included, its title is marked in bold print in the text. Due to potential copyright restrictions, the access to the remaining image clusters can require compliance with specific terms of use. I have therefore made the complete set of image clusters (IC 001 to IC 195) available via this research repository
Primary Somatosensory Cortex Bidirectionally Modulates Sensory Gain and Nociceptive Behavior in a Layer-Specific Manner [Research Data]
No full textThis dataset contains electrophysiological and behavioral data and codes underlying the figures in Ziegler, K., Folkard, R., Gonzalez, A.J. et al. Primary somatosensory cortex bidirectionally modulates sensory gain and nociceptive behavior in a layer-specific manner. Nat Commun 14, 2999 (2023). https://doi.org/10.1038/s41467-023-38798-7
Abstract:
The primary somatosensory cortex (S1) is a hub for body sensation of both innocuous and noxious signals, yet its role in somatosensation versus pain is debated. Despite known contributions of S1 to sensory gain modulation, its causal involvement in subjective sensory experiences remains elusive. Here, in mouse S1, we reveal the involvement of cortical output neurons in layers 5 (L5) and 6 (L6) in the perception of innocuous and noxious somatosensory signals. We find that L6 activation can drive aversive hypersensitivity and spontaneous nocifensive behavior. Linking behavior to neuronal mechanisms, we find that L6 enhances thalamic somatosensory responses, and in parallel, strongly suppresses L5 neurons. Directly suppressing L5 reproduced the pronociceptive phenotype induced by L6 activation, suggesting an anti-nociceptive function for L5 output. Indeed, L5 activation reduced sensory sensitivity and reversed inflammatory allodynia. Together, these findings reveal a layer-specific and bidirectional role for S1 in modulating subjective sensory experiences
[4+4]-Imine Cage Compounds with Nitrogen-Rich Cavities and Tetrahedral Geometry [Data]
No full textOrganic imine cage compounds have found a variety of different applications in several fields in materials science. To design tailor-made cages for corresponding applications, synthetic approaches to cages with tunable functionalities, sizes and shapes have to be found. Here we report a series of cages with truncated cubic shape and tetrahedral geometry possessing nitrogen-rich cavities
Etheno-bridged Azaacene Spiro Dimers [data]
No full textWe present the synthesis of two sets of spiro-connected azaacene dimers. Their geometry and electronic coupling are critically determined by a secondary linker, i.e. an etheno- and an ethano-bridge.The core fragment of the etheno-bridged dimer corresponds to a conformationally locked cis-stilbene. Optoelectronic properties, single crystal X-ray structures and stability with respect to oxidation of the conjugated and non-conjugated dimers are reported and compared. The conjugated dimers exhibit smaller optical gaps and bathochromically shifted absorption maxima, but are prone to unexpected oxygen addition, dearomatizing one of the azaacene substituents
