Most models explaining polygyny in birds have concentrated on variation in male or territorial quality, ignoring the role of females in maintaining monogamy. Although field observations have suggested that already mated females may maintain monogamy by either behaving aggressively toward prospecting females or by interupting male mate attraction behaviour, no experiments have been done to test if

Within the framework of the EU-financed project MASTER field trials with in-car speed limiter were carried out in three “region-typical” countries: Sweden, the Netherlands, and Spain. The speed limiter is an active gas pedal which provides a gas pedal counter-force whenever the driver tries to depress the pedal beyond a pre-set speed limit. Twenty subjects per country drove two times along the tes

Several recent studies of solar twins in the solar neighbourhood have shown a tight correlation between various elemental abundances and age, in particular [Y/Mg]. If this relation is real and valid for other types of stars as well as elsewhere in the Galaxy, it would provide a very powerful tool to derive ages of stars without the need to resort to determining their masses (evolutionary stage) ve

In stable biological and ecological networks, the steady-state influence matrix gathers the signs of steady-state responses to step-like perturbations affecting the variables. Such signs are difficult to predict a priori, because they result from a combination of direct effects (deducible from the Jacobian of the network dynamics) and indirect effects. For stable monotone or cooperative networks,

The Øresund Region that connects Copenhagen metropolitan area in Denmark and Southern Sweden is an interesting example of a European cross-border collaboration. In this article, the contemporary development of the region and the place branding process is described. The aim is to increase understanding of how a complex and bi-national place brand is developed in a process of continuous change due t

This study investigates how public sector organizations generate authority in social media crisis. Furthermore, it examines how genres of governance, namely genre chain and genre mixing, contribute to the generation of authority. On this basis of an interdisciplinary theoretical framework consisting of the concepts of “network governance” and “authority,” a genre analysis of 100 top forwarded post

The contribution of Rafael Capurro to the clarification of the uses of the concept of information has a conceptual as well a historical dimension; in this last sense, there are few philosophers of information that can follow the history of the concept of information in the works of the Classics with the accuracy and erudition of Capurro We find that his contribution embraces the following fields:

Today’s communities are characterized by migration, transnationalism, and participation in the global economy, and many also have long local histories of linguistic diversity. Empowering individuals in these contexts means fostering the ability to use and expand their existing linguistic repertoires so they can take advantage of the social and economic opportunities afforded by contemporary life.

The base-quenched probe method for detecting single nucleotide polymorphisms (SNPs) relies on real-time PCR and melting-curve approaches. Here, we applied the most common commercial fluorophores including FAM, HEX, CY5, CY3, TET, JOE, Texas Red and ROX for labeling probes to detect multi-mutations simultaneously according to the different fluorescence channels. Accuracy of the method was confirmed

Introduction: The interaction between different product policies will be crucial for the further advancement of a coherent product policy framework. The Commission has stated that ‘the complex and interlocking approach needed to build a resource-efficient Europe can only be achieved with a policy mix that optimizes synergies and addresses trade-offs between different areas and policies’. In the co

colon; Prompted by previous studies suggesting that bulimia nervosa in women may be associated with elevated serum levels of testosterone, we have evaluated the possible effect of androgen antagonism in this condition. To this end, women meeting the DSM-IV criteria of bulimia nervosa, purging type, were treated in a one-center study with the androgen receptor antagonist flutamide (n = 9), the sero
