This study explores the reduction potential of greenhouse gases for major pollution emitting countries of the world using nonparametric productivity measurement methods and directional distance functions. In contrast to the existing literature we apply optimization methods to endogenously...

[Zielsetzung / Abgrenzung] Die 'Schreckensherrschaft der EDV-Abteilung ist vorbei' - so der Titel eines Zeitungsartikels. Bereits vor einigen Jahren prophezeite Nicolas Carr 'the End of Corporate Computing'. Haben wir diesen Zeitpunkt inzwischen erreicht? Haben neue Technologien und...

Cross-border production networks have been playing an increasingly important role in the Association of Southeast Asian Nations (ASEAN) countries’ trade in recent years, but micro-level studies are rare. This paper uses firm-level data from the two most active ASEAN countries in production...

This paper examines the role of international trade in employment growth in micro- and small enterprises using a representative sample of manufacturing firms in six Southeast Asian countries. After controlling for firm and individual characteristics as well as country and sector dummies,...

We calculate the effective reaction rate constant k∗ and the effective diffusion constant D∗ for a system of independently distributed overlapping sinks as functions of the volume fraction φ of the sinks and the Sherwood number Sh. The Sherwood number characterises the strength of the...

We calculate the effective reaction rate constant k∗ and the effective diffusion constant D∗ for a system of randomly distributed imperfect spherical sinks. Imperfect means in this context that the surface reaction rate is finite. We use an effective medium theory presented in a previous...

We calculate the effective rate constant k∗ and the effective diffusion constant D∗ of diffusion-controlled reactions in a random array of perfectly absorbing spherical sinks. We use the effective medium approach developed by Cukier, Freed and Muthukumar. In contrast to their work we take...

Business and Information Systems Engineering (BISE) is at a turning point. Planning, designing, developing and operating IT used to be a management task of a few elites in public ad-ministrations and corporations. But the continuous digitization of nearly all areas of life changes the IT...
