Fairness, Price Stickiness, and History Dependence in Decentralized Trade

The paper investigates price formation in a decentralized market with random matching. Agents are assumed to have subdued social preferences: buyers, for example, prefer a lower price to a higher one but experience reduced utility increases below a reference price which serves as a common fairness benchmark. The strategic equilibrium reflects market fundamentals, but it is markedly less sensitive to the buyer-seller ratio near the fair price benchmark. Prices may be sticky around very dierent reference levels in markets with otherwise identical fundamentals. The implied history dependence turns out to be mitigated rather than exacerbated by friction.random matching, price stickiness, social preferences, history dependence, reference dependence

A Comparative Study on the Influence of DC/DC-Converter Induced High Frequency Current Ripple on Lithium-Ion Batteries

Modern battery energy systems are key enablers of the conversion of our energy and mobility sector towards renewability. Most of the time, their batteries are connected to power electronics that induce high frequency current ripple on the batteries that could lead to reinforced battery ageing. This study investigates the influence of high frequency current ripple on the ageing of commercially available, cylindrical 18,650 lithium-ion batteries in comparison to identical batteries that are aged with a conventional battery test system. The respective ageing tests that have been carried out to obtain numerous parameters such as the capacity loss, the gradient of voltage curves and impedance spectra are explained and evaluated to pinpoint how current ripple possibly affects battery ageing. Finally, the results suggest that there is little to no further influence of current ripple that is severe enough to stand out against ageing effects due to the underlying accelerated cyclic ageing

A Critical Reconstruction of Care-in-Action

This paper uses the findings of a critical ethnography studying the interactions of adult colleagues (Korth, 1998) to propose a critical approach to care theory and research. The argument proceeds from Jaggar\u27s (1995) critique of the scholarship on care. Her criticism voices concerns regarding the lack of attention to the justificatory potential of care research/theory and the over-dependence on particularities. This paper provides one set of responses capable of addressing these concerns and of reformulating the concerns into a more complex conceptualization of care. The resulting analysis implies a theory of care as a pragmatic-communicative construct, one that is more precise, but compatible with the interpersonal rationality to which Noddings (1991) attributes caring. Care emerges as a communicative act with a complex but definitive horizon structure. Care did not reconstruct from on-going interactions as a simple intention, nor a feeling, nor anything extra-rational or non-rational. This approach to understanding caring locates Jaggars concerns within the interpretive life of interactants. The papers specific contributions include exemplifying a refined analysis of care-in-action, articulating a meta-theory useful for the theory and study of care, introducing a typology of caring acts, demonstrating the critical potential of care research, and illustrating the connection between critique and justification

Abundances of Suprathermal Heavy Ions in CIRs during the Minimum of Solar Cycle 23

In this paper we examine the elemental composition of the 0.1-1 MeV/nucleon interplanetary heavy ions from H to Fe in corotating interaction regions (CIRs) measured by the SIT (Suprathermal Ion Telescope) instrument. We use observations taken on board the STEREO spacecraft from January 2007 through December 2010, which included the unusually long solar minimum following solar cycle 23. During this period instruments on STEREO observed more than 50 CIR events making it possible to investigate CIR ion abundances during solar minimum conditions with unprecedented high statistics. The observations reveal annual variations of relative ion abundances in the CIRs during the 2007-2008 period as indicated by the He/H, He/O and Fe/O elemental ratios. We discuss possible causes of the variability in terms of the helium focusing cone passage and heliolatitude dependence. The year 2009 was very quiet in CIR event activity. In 2010 the elemental composition in CIRs were influenced by sporadic solar energetic particle (SEP) events. The 2010 He/H and He/O abundance ratios in CIRs show large event to event variations with values resembling the SEP-like composition. This finding points out that the suprathermal SEPs could be the source population for CIR acceleration.Comment: accepted for publication in Solar Physic

The relationship between stress and syntax in German

The following paper is intended to show how metrical structure of German verb-final sentences can be derived from syntactic and information-structural cues by taking the syntactic relationship and the information status of adjacent syntactic constituents into consideration. It will be argued that the syntactic structure has to be supplemented by focus features rather than by givenness features and that focus features need to be restricted to foreground domains to derive the correct stress pattern
