How Does Temporal Resolution Influence Geomagnetic Reversal Statistics?

How Does Culture Influence Conflict Resolution? a Dynamic Constructivist Analysis

Psychologists have taken several approaches to modeling how culture influences the ways individuals negotiate interpersonal conflict. Most common has been the approach of searching for cultural traits-general, stable value-orientations that predict a variety of culturally typical conflict resolution behaviors. Increasingly researchers have adopted a constructivist approach of locating the nexus...

Geomagnetic reversal through critical models

Geomagnetic polarity reversal intervals display power law distribution functions, which indicate a critical phenomenon as the mechanism of their source. The geodynamo is assumed to be a system of magnetic spins in a critical phase-transition state. Seki and Ito developed two models to simulate these reversals: the N-disc coupled model and the Coupled map lattice model both derived from the Riki...

How Neuronal Oscillations Code for Temporal Statistics

Does Morphology Influence Temporal Plasticity?

Applying bounded weight-independent temporal plasticity rule to synapses from independent Poisson firing presynaptic neurons onto a conductance-based integrate-and-fire neuron leads to a bimodal distribution of synaptic strength (Song et al., 2000). We extend this model to investigate the effects of spreading the synapses over the dendritic tree. The results suggest that distal synapses tend to...

How does climate influence speciation?

Variation in climatic conditions over space and time is thought to be an important driver of speciation. However, the role of climate has not been explored in the theoretical literature on speciation, and the theory underlying empirical studies of climate and speciation has come largely from informal, verbal models. In this study, we develop a quantitative model to test a relatively new but the...
