Unlike in other disciplines, research output in economics is commonly measured based on the journal titles in which an author has published. Here, I examine how much output measures based on journal titles tell us about the academic interest and relevance of economic papers as measured by citation frequency. Using data from the 2008 Handelsblatt ranking of economists in German speaking countries and interdisciplinary citation data from ...

The authors employ a generic analytical framework to analyse conflicts in the three case study countries, which differentiates between conflict dynamics (actions and events) and the more profound calculations of the conflict parties, based on material incentives, normative frameworks and other structural preconditions. Guided by the analytical framework, the paper includes a descriptive account of how the 'tormented triangle' took shape ...

A general stochastic maximum principle is proved for optimal controls of semilinear stochastic evolution equations. Stochastic evolution operators, and the control with values in a general set enter into both drift and diffusion terms.

It has been shown that the heating, ventilation, and air conditioning (HVAC) systems of commercial buildings can offer ancillary services to power systems due to their large thermal inertia. In this paper, we propose a new control framework for scheduling and provision of frequency reserves by commercial building aggregations. The framework builds on a hierarchical control scheme: first, the reserve capacities are allocated among the ...
