Comparative psychology is a strongly interdisciplinary field that shares many of its experimental methods and observational techniques with ethology and developmental psychology. The great variety of theories that comparative psychology evokes to explain behavior generates a wide array of exciting and potentially fruitful accounts, but is also problematic. It increases the risk of error in the for
With the assumed digitalisation happening on the end-user side, progressive systems integrators stress the importance of changing the business concept from being installers to being service and solution providers. However, less is known about the details of this process on the end-user side. Based on an online survey of loss prevention managers it can be stated that security digitalisation and fur
The paper opens by generalizing the concept of 'informing science'. It then introduces some meta-scientific perspectives and a discussion of a metaphor that has considerable explanatory power. Two main schools of metascience are presented and contrasted. The difference between treating invariances in natural sciences and in social and cultural sciences is discussed. The double helix is introduced
The experience acquired over a period of 15 years of diagnostic electron microscopy of fine needle aspirates and surgical specimens constitutes the base for this thesis. Some of the tumors analyzed represent rare soft tissue tumors, and consequently not very often ultrastructurally described. In locations where sarcomas are rare and unexpected, electron microscopy may contribute to a correct tumor
Zabrze is a medium size town of 200 000 inhabitants in the region of Upper Silesia, Poland. The development of the town was originally based on the exploitation of heavy industries. In the past few years Zabrze has, however, moved towards more service and tourism oriented industries. As part of this journey, the city of Zabrze sees the need to improve its existing waste management system. This rep
An optimization approach to a multi-dimensional acoustic inverse problem in the time domain is considered. The density and/or the velocity are reconstructed by minimizing an objective functional. By introducing dual functions and using the Gauss divergence theorem, the gradient of the objective functional is found as an explicit expression. The parameters are then reconstructed by an iterative alg
In reply to Welzel and Inglehart in this issue, we deploy three lines of criticism. First, we argue that their newly invented construct "effective democracy" is conceptually and empirically flawed. Second, we show that their results are highly sensitive to model specification. Regardless of the time period, their supportive evidence vanishes if a more pertinent measure of democracy is used instead
