A micro-level 'consumer approach' to species population dynamics
Christiaans, Thomas; Eichner, Thomas; Pethig, Rüdiger - 2005
-level ecosystem model. For the case of a single species our model is shown to yield the well-known Verhulst-Pearl logistic growth … biomass transactions and net offspring which directly translates into population growth functions. We are able to explicitly … determine these growth functions for a simple food web when specific parametric net offspring functions are chosen in the micro …

Conflicts and political intervention: Evidence from the anti-open grazing laws in Nigeria
Hufschmidt, Patrick; Ume, Chukwuma Otum - 2023
This paper empirically investigates the effects of Anti-Open Grazing Laws (AOGLs) on herder-farmer conflicts in Nigeria. The laws, enacted as a response to escalating violent conflicts over fertile land resources between herders and farmers, aimed to reduce clashes by prohibiting livestock...

Social capital determinants of preferential resource allocation in regional clusters
Pulles, Niels J.; Schiele, Holger - In: Management Revue 24 (2013) 2, pp. 96-113
Regional clusters are known to facilitate firms in achieving higher levels of competitive advantage. This observation suggests that cluster firms manage to obtain better competitive resources than firms outside the cluster. The strong social ties in regional clusters are considered to be a...

Chasing the smokestack: Strategic policymaking with multiple instruments
Fredriksson, Per G.; List, John A.; Millimet, Daniel L. - 2002
Recent studies suggest a considerable amount of horizontal strategic interaction amongst governments exists. The empirical approach in these studies typically relies on estimating reaction functions in a uni-dimensional policy framework, where a nonzero slope estimate suggests strategic...

A power law distribution in patients’ lengths of stay in hospital
Hellervik, A.; Rodgers, G.J. - In: Physica A: Statistical Mechanics and its Applications 379 (2007) 1, pp. 235-240
The distribution of patients’ lengths of stay in English hospitals is measured by using routinely collected data from 11 years. It is found to be well approximated by a power law distribution spanning over more than three decades. To explain this observation, a theoretical resource allocation...
