Die Another Day: Duration in German Import Trade

International trade patterns at the product level are surprisingly dynamic. The majority of trade relationships exist for just a few, often only two to four, years. In this paper, I examine empirically the duration in German import trade at the 8-digit product level from 1995 to 2005. I find that survival probabilities are affected by product type, exporter characteristics and market structure. Specifically, I show that the duration of exporting a product to Germany is longer for differentiated products, for products with a low elasticity of substitution, for products obtained from a large exporter that is geographically close to the German market, and for products in markets with increasing import demand.Survival, product, relationship, pattern

Die another day: duration in German import trade

International trade patterns at the product level are surprisingly dynamic. The majority of trade relationships exist for just a few, often only one to three, years. In this paper, I examine empirically the duration in German import trade at the 8-digit product level from 1995 to 2005. I find that survival probabilities are affected by exporter characteristics, product type and market structure. Specifically, I show that the duration of exporting a product to Germany is longer for products obtained from countries that are economically large and geographically close to Germany; for products with large trade value and a low elasticity of substitution; and for trade pairs that command a large share of the German import market and are characterized by two-way trade. --Survival,product,relationship,pattern

Will They Die Another Day? A Decision Support Perspective on Reusing Electric Vehicle Batteries

The diffusion of electric mobility suffers from an immature and expensive battery technology. Reusing electric vehicle batteries (EVBs) is a prospective opportunity for lowering the total costs of ownership of electric vehicles and using scarce natural resources more efficiently. However, to determine how to reuse a battery is a complex decision problem. In this study we set out to develop a design theory for a class of decision support systems (DSSs) that implement two main functions: First, a consideration set of feasible reuse scenarios is compiled based on an assess-ment of a battery’s structure and condition. Second, an offering is configured based on bun-dling batteries with customized services. We conclude with an outlook to our ongoing design science project that will, amongst others, explore to what extent systems instantiated from the design theory can remedy adverse effects caused by the ‘lemon market’ properties of the sec-ond-hand battery market

Too Cool to Smoke : Using Puppets to Make Learning Fun

Introduction: According to the American Cancer Society, each day, more than 4,000 teens try cigarettes for the first time, and another 2,000 become daily smokers. One-half of these teens eventually will die from a smoking-related disease. [See PDF for complete abstract

Live to die another day: the rebrightening of AT2018fyk as a repeating partial tidal disruption event

Stars that interact with supermassive black holes (SMBHs) can either be completely or partially destroyed by tides. In a partial tidal disruption event (TDE) the high-density core of the star remains intact, and the low-density, outer envelope of the star is stripped and feeds a luminous accretion episode. The TDE AT2018fyk, with an inferred black hole mass of $10^{7.7\pm0.4}$ M$_{\odot}$, experienced an extreme dimming event at X-ray (factor of $>$6000) and UV (factor $\sim$15) wavelengths $\sim$500--600 days after discovery. Here we report on the re-emergence of these emission components roughly 1200 days after discovery. We find that the source properties are similar to those of the pre-dimming accretion state, suggesting that the accretion flow was rejuvenated to a similar state. We propose that a repeating partial TDE, where the partially disrupted star is on a $\sim 1200$ day orbit about the SMBH and is periodically stripped of mass during each pericenter passage, powers its unique lightcurve. This scenario provides a plausible explanation for AT2018fyk's overall properties, including the rapid dimming event and the rebrightening at late times. We also provide testable predictions for the behavior of the accretion flow in the future: if the second encounter was also a partial disruption then we predict another strong dimming event around day 1800 (August 2023), and a subsequent rebrightening around day 2400 (March 2025). This source provides strong evidence of the partial disruption of a star by a SMBH.Comment: ApJ Letters, accepted for publicatio

Die Another Day: Sarpedon, Aristodemos, and Homeric Intertextuality in Herodotus

The subject of this chapter is a single contested word in Herodotus' Histories. In it I explore its semantic range and use it to think about broader questions of Herodotus’ interplay with Homer. Where many of the Homeric touches in Herodotus can be put down to, and more productively used, as examples of traditional referentiality or, at least, non-specific resonances with the Iliad, the presence of the hapax λιποψυχέω in our manuscripts suggests a prosaic reworking of the poetic formula ‘his spirit left him’, and a specific intertext with the moment when this utterance is applied to Sarpedon’s spirit leaving him as he loses consciousness
