Die Burnoutprävalenz der luxemburgischen Arbeitnehmer liegt für 2013 bis 2015 zwischen 15,7 und 18,0%. Während Frauen 2013 eine höhere Burnoutprävalenz im Vergleich zu Männern aufweisen, verringert sich diese Differenz 2014 und 2015 etwas. Die 25-34 Jährigen Arbeitnehmer scheinen seltener von Burnout betroffen zu sein. Demgegenüber weisen die 35-44 und 45-54 Jährigen über alle drei Erhebungsjahre überdurchschnittliche Burnoutprävalenzen auf. Differenziert man die Arbeitnehmer nach Voll- und Teilzeitstellen, ergeben sich nur geringfügige Unterschiede. Arbeitnehmer, die 0-5 Jahre in ihrem jetzigen Betrieb arbeiten sind im Vergleich zu Arbeitnehmern mit einer längeren Betriebszugehörigkeitsdauer unterdurchschnittlich von Burnout betroffen. Arbeitnehmer, die eine Reduktion der Belegschaft in ihrem Betrieb konstatieren, sind deutlich stärker von Burnout betroffen, als Personen, die keine Veränderung oder sogar eine Erhöhung der Belegschaft festgestellt haben. Arbeitnehmer, die von Aktionen zur Aufklärung von Gesundheitsproblemen in ihrer Organisation berichten, sind ebenfalls weniger stark von Burnout betroffen im Vergleich zu Arbeitnehmern, die berichten, dass in den letzten drei Jahren keine Aktionen zur Aufklärung von Gesundheitsproblemen stattgefunden haben. Differenziert man die Arbeitnehmer nach ISCO-Berufsklassifikation, ist die Burnoutprävalenz unter Managern bzw. Führungskräften am Geringsten, bei Arbeitnehmern die Anlagen bedienen und Montageberufen als auch bei Technikern dagegen am höchsten. Arbeitnehmer mit deutscher und luxemburgischer Nationalität sind seltener, Arbeitnehmer mit französischer und belgischer Nationalität dagegen öfter von Burnout betroffen. [less ▲]

We give a rigorous construction of solutions to the Euler point vortices system in which three vortices burst out of a single one in a configuration of many vortices, or equivalently that there exist configurations of arbitrarily many vortices in which three of them collapse in finite time. As an intermediate step, we show that well-known self-similar bursts and collapses of three isolated vortices in the plane persist under a sufficiently regular external perturbation. We also discuss how our results produce examples of non-unique weak solutions to 2-dimensional Euler's equations -- in the sense introduced by Schochet -- in which energy is dissipated. [less ▲]

Rapid growth of intermittent renewable power generation makes the identification of investment opportunities in energy storage and the establishment of their profitability indispensable. Here we first present a conceptual framework to characterize business models of energy storage and systematically differentiate investment opportunities. We then use the framework to examine which storage technologies can perform the identified business models and review the recent literature regarding the profitability of individual combinations of business models and technologies. Our analysis shows that a set of commercially available technologies can serve all identified business models. We also find that certain combinations appear to have approached a tipping point toward profitability. Yet, this conclusion only holds for combinations examined most recently or stacking several business models. Many technologically feasible combinations have been neglected, indicating a need for further research to provide a detailed and conclusive understanding about the profitability of energy storage.

Verifying whether a business process is compliant with a regulatory framework is a difficult task. In the present paper we prove the hardness of the business process regulatory compliance problem by taking into account a sub-problem of the general problem. This limited problem allows to verify only the compliance of structured processes with respect to a regulatory framework composed of a set of conditional obligations including a deadline. Experimental evidence from existing studies shows that compliance is a difficult task. In this paper, despite considering a sub-problem of the general problem, we provide some theoretical evidence of the difficulty of the task. In particular we show that the source of the complexity lies in the core language of verifying conditional obligations with a deadline. We prove that for this simplified case verifying partial compliance belongs to the class of NP-complete problems, and verifying full compliance belongs to the class of coNP-complete problems. Thus by proving the difficulty of a simplified compliance problem we prove that the general problem of verifying business process regulatory compliance is hard. [less ▲]
