This neoclassical approach explains noncompliance fairly well, but anomalies exist. Evenly parsimonious, Alejandro Portes develops a institutional...

A common strategy for the analysis of object-attribute associations is to derive a low-dimensional spatial representation of objects and attributes which involves a compensatory model (e.g., principal components analysis) to explain the strength of object-attribute associations. As an...

The present study investigated the extent to which verbal intelligence (VIQ) and performance intelligence (PIQ) contribute to strategy selection and execution in the context of a numerosity judgement task. The choice/no-choice method was used to appropriately assess strategy selection (in terms...

Probabilistic feature models (PFMs) can be used to explain binary rater judgements about the associations between two types of elements (e.g., objects and attributes) on the basis of binary latent features. In particular, to explain observed object-attribute associations PFMs assume that...

Hard data alone are not sufficient to evaluate local police effectiveness in the new age of community policing. Citizens can provide useful feedback regarding strengths and weaknesses of police operations. However, citizen satisfaction indicators typically fail to accurately convey the...

Both sides of a two-sided market are usually modeled as markets without product differentiation. Often however,it will be profit maximizing to differentiate one or two sides in two or more types. In a simple theoretical model,inspired by Yellow Pages,we show that this decision crucially depends...
