Auf der Grundlage einer repräsentativen Befragung von Arbeitnehmenden in der Schweiz werden die Zusammenhänge zwischen flexiblen Arbeitszeitregelungen und der Arbeitssituation der Befragten untersucht. Im Mittelpunkt steht dabei die Frage nach der obligatorischen Erfassung / Nicht-Erfassung...

There is a need for economic restructuring (also called transformation) to safeguard our natural resources, which our economy relies upon. To address global challenges in the use of bio-resources, the three dimensions of sustainable development need to be accounted for: environmental, social,...

Microarrays enable to measure the expression levels of tens of thousands of genes simultaneously. One important statistical question in such experiments is which of the several thousand genes are differentially expressed. Answering this question requires methods that can deal with multiple...

Online offerings such as web search, news portals, and e-commerce applications face the challenge of providing high-quality service to a large, heterogeneous user base. Recent efforts have highlighted the potential to improve performance by introducing methods to personalize services based on...

In der vorliegenden Stellungnahme setzt sich das Thünen-Institut mit der Frage auseinander, wie sich wichtige Strategiepapiere, die die EU-Kommission und die Bundesregierung im zurückliegenden Jahr veröffentlicht haben, voraussichtlich auf Landwirtschaft, Forstwirtschaft und Fischerei...

We propose a prediction model based on the minority game in which traders continuously evaluate a complete set of trading strategies with different memory lengths using the strategies' past performance. Based on the chosen trading strategy they determine their prediction of the movement for the...

We simulate a series of daily returns from intraday price movements initiated by microstructure elements. Significant evidence is found that daily returns and daily return volatility exhibit first order autocorrelation, but trading volume and daily return volatility are not correlated, while...

It has been widely accepted that herding is the consequence of mimetic responses by agents interacting locally on a communication network. In extant models, this communication network linking agents, by and large, has been assumed to be fixed. In this paper we allow it to evolve endogenously by...
