The software industry has become a key industry in many developing countries because of the application of information technology in business, manufacturing and many other sectors. Software development produces higher value addition compared to other industries with more skilled human resources. Software project management is an interesting issue of both researchers and managers. Software...

FiRe is a user-friendly Excel® macro designed to survey microarray data rapidly. This software interactively assembles data from different experiments and produces lists of candidate genes according to patterns of gene expression. Furthermore, macros bundled with FiRe can compare lists of genes, merge information from different spreadsheets, link candidates to information available from...

This research documents the empirical results of intentional change in an organizational identity where resistance emerges. We develop and test a theoretical model describing why members of an organization in such situations of change perceive a threat of organizational identity traits. Research results illustrate that the essentiality of organizational identity traits and their influence on...

This paper documents the empirical results of a field study conducted among top Swiss companies. The survey investigates their practices in Corporate Social Responsibility (CSR) communication as well as their opinions about how favorable the Swiss context is for this kind of communication. Results show CSR communication in Switzerland as a practice in evolution, still needing expertise. In this...

A typical problem arising in the financial planning for private investors consists in the fact that the initial investor’s portfolio, the one determined by the consulting process of the financial institution and the universe of instruments made available to the investor have to be matched/optimized when determining the relevant portfolio choice. We call this problem the three-portfolios...

We tested whether alpine plants increase their effort to attract pollinators to compensate for assumed pollinator scarcity at high altitude. A three times larger fraction of the shoot was allocated to flowers in alpine plants (30 species, 2700m asl) compared to lowland plants (20 species, 600m asl), while leaf mass fraction did not differ between the altitudes. At high elevation, a three times...

This doctoral thesis deals with the question of how self-images change when people are getting into the age of retirement. Two main issues are addressed regarding the development of personal identities in that life stage: (1) The content of identity: the question if and how retired people have a different way of defining or characterizing themselves than employed people. (2) The age identity...

Let M and N be compact smooth Riemannian manifolds without boundaries. Then, for a map u : M→N, we consider a class of energies which includes the popular Dirichlet energy and the more general p-energy. Geometric or physical questions motivate to investigate the critical points of such an energy or the corresponding heat flow problem. In the case of the Dirichlet energy, the heat flow...

This study investigated expansion strategies of international hotel operators in Eastern Central Europe. Due to the growing importance of services in economic development, there is an impressive body of knowledge on the process of internationalization and service industries. The last comprehensive academic study on internationalization and the hotel industry was undertaken at the beginning of the...
