Phenological timing–i.e. the course of annually recurring development stages in nature–is of particular interest since it can be understood as a proxy for the climate at a specific region; moreover changes in the so-called phenological phases can be a direct consequence of climate change. We...

We use the Detrended Fluctuation Analysis (DFA) to quantify underlying trends in long-term correlated records. Our approach is based on the fact that different orders of DFA are affected differently by trends. For a given instrumental record of length N, we compare the fluctuation exponent α0...

Das Ziel der Machbarkeitsstudie "Forschermobilität und Innovation" war es, Datenquellen und methodische Ansätze zu identifizieren, durch welche die internationale Mobilität von Forschen mit Deutschland als Ziel- und Herkunftsland besser als bislang erfasst und analysiert werden kann. Es...

The purpose of this paper is to contribute to the empirical ‘world city network’ (WCN) literature by proposing an analytical framework that considers the significance of the positions of cities in the urban networks created by multinational corporations. To this end, we introduce an approach...

Network information on geographical entities such as cities is frequently analysed numerically, but seldom visualised in an appealing form. Reasons for this include the absence of powerful software that is capable of handling large-scale networks and the layout of this information without...
