On deformations of triangulated models Universiteit Antwerpen
This paper is the first part of a project aimed at understanding deformations of triangulated categories, and more precisely their dg and A∞A∞ models, and applying the resulting theory to the models occurring in the Homological Mirror Symmetry setup. In this first paper, we focus on models of derived and related categories, based upon the classical construction of twisted objects over a dg or A∞A∞-algebra. For a Hochschild 2 cocycle on such a ...
Physical activity in adults with controlled and uncontrolled asthma as compared to healthy adults Universiteit Antwerpen
Background Though exercise-induced bronchoconstriction is common among asthmatics, physical activity (PA) seems important in asthma management. Still, various studies point at avoidance of sports and certain daily life activities like walking stairs, even by patients with mild symptoms. We aimed to compare physical activity levels between healthy subjects and asthmatics with controlled and uncontrolled disease. Methods Data on asthma and PA were ...
L'entrepreneur ambitieux: état des lieux et perspectives Universiteit Antwerpen
Larticle présente les développements récents sur le thème de l« entrepreneur ambitieux », cet entrepreneur qui sengage dans le processus entrepreneurial dans le but datteindre des performances qui dépassent la simple survie de lactivité créée dans un environnement concurrentiel.

A strategic perspective on IT outsourcing Universiteit Antwerpen
In the current business environment IT outsourcing has gained prominence. Many firms in Europe outsource their IT requirements to Asia. This study analyzes the factors which favor this trend in which clients are based in Europe and vendors are based in Asia. From a strategic perspective, this study identifies the characteristics that IT activities must possess for them to be outsourced from Europe to Asia. In addition to contributing to academic ...
R&D competition versus R&D cooperation in oligopolistic markets with evolving structure Universiteit Antwerpen
This paper considers investment behavior of duopolistic firms subject to technological progress. It is assumed that initially both firms offer a homogeneous product, but after a stochastic waiting time they are able to implement a product innovation. Production capacities of both firms are product specific. It is shown that firms anticipate a future product innovation by under-investing (if the new product is a substitute to the established ...
Het belang van de eigendomsstructuur bij de beslissing tot vrijwillige overschakeling naar IFRS voor Belgische niet-beursgenoteerde ondernemingen Universiteit Antwerpen
Alvorens de internationale accounting standaarden in 2005 verplicht werden, schakelden een aantal beursgenoteerde ondernemingen al vrijwillig over naar deze standaarden. De wetgever in België opteerde ervoor om ook de niet-beursgenoteerde ondernemingen toe te staan om de geconsolideerde jaarrekening op te stellen overeenkomstig de internationale boekhoudnormen. De beslissing om over te schakelen naar IFRS is dus voor Belgische ...
Bestrijding van (boekhoudkundige) fraude, al dan niet gebaat met publiek-private samenwerking Universiteit Antwerpen
Lexicographical dynamic goal programming approach to arobust design optimization within the pharmaceutical environment Universiteit Antwerpen
The primary objective ofthis paper istodevelop anew robust design (RD)optimization procedure based on alexicographical dynamic goal programming (LDGP)approach for implementing time-series based multi-responses, while the conve ntional experimental design formats and frameworks may implement static responses. First,aparameter estimation method for time-dependent pharmaceutical responses (i.e., drug release and gelati onkinetics)isproposed using ...
