German Perception Verbs: Automatic Classification of Prototypical and Multiple Non-literal Meanings

This paper presents a token-based automatic classification of German perception verbs into literal vs. multiple non-literal senses. Based on a corpus-based dataset of German perception verbs and their systematic meaning shifts, we identify one verb of each of the four perception classes optical, acoustic, olfactory, haptic, and use Decision Trees relying on syntactic and semantic corpus-based features to classify the verb uses into 3-4 senses each. Our classifier reaches accuracies between 45.5% and 69.4%, in comparison to baselines between 27.5% and 39.0%. In three out of four cases analyzed our classifier’s accuracy is significantly higher than the according baseline

Mechanisms of Dendritic Shorting in Lithium Metal Batteries with Li7La3Zr2O12 Solid Electrolytes

Energy storage will play a crucial role in efforts to mitigate the effects of climate change caused by greenhouse gas emissions from human activity. Lithium metal batteries using solid electrolytes like Li7La3Zr2O12 have higher energy density than lithium-ion batteries, which may enable a more rapid and complete electrification of transportation. However, lithium metal batteries suffer from undesirable short-circuiting when metallic lithium deposits connect the two electrodes. It has been debated whether these lithium dendrites generally grow directionally from the anode or are generated by the reduction of lithium ions inside the solid electrolyte, but a recently proposed model may allow for a unification of these two competing theories by focusing on hollow voids in the interior of the electrolyte as the origin of dendrite nucleation. Clear approaches for the suppression of dendrite nucleation arise from this new theory, including the densification of the electrolyte or the use of lithium alloys as the anode. If additional experiments can further corroborate basic elements of this model, it could be extended to include the electronic and mechanical properties of grain boundaries in polycrystalline solid electrolytes like Li7La3Zr2O12 and thereby gain additional predictive power

Performing Victory: The Different Kind of War of Bush 43

In the pieces to camera that George W. Bush has delivered since 9/11, the ideals of “victory” and “freedom” have driven the arguments for initiating, prolonging and sustaining belligerent action—bello jus—against a number of different targets. The arguments by which the “different kind of war” is conceptualised and justified have their basis upon the acts that are considered to have provoked the need for war, namely the acts of 9/11. This paper examines ways in which the performance of “presidency”—particularly as the “war president”—has generated and maintained the performative conditions of armed conflict, as well as ways in which those performative conditions have been interrupted and eroded over time.The conference was sponsored by A.D.S.A., the Department of Performance Studies, the School of Letters, Arts and Media, and the Faculty of Arts of the University of Sydney
