for helpful suggestions concerning the design of the experiment.
Studies designed to understand species distributions and community assemblages typically use separate analytical approaches (e.g., logistic regression and ordination) to model the distribution of individual species and to relate community composition to environmental variation. Multilevel models (MLMs) offer a promising strategy for integrating species and… (More)
1 Deregulation through temporary employment has generated important inequalities in the Spanish labour market. The paper presents a theoretical model as well as empirical evidence to explain this process. The main thrust of the model is seeing labour market structures as always being the result of micro-level strategies of employers and employees over… (More)
North America's coastal mountains are particularly vulnerable to climate change, yet harbour a number of endemic species. With little room "at the top" to track shifting climate envelopes, alpine species may be especially negatively affected by climate-induced habitat fragmentation. We ask how climate change will affect the total amount, mean patch size,… (More)
BACKGROUND There are an estimated 35 million unregistered children in Indonesia. To understand ways to best leverage existing health system-related resources and ensure greater protective measures for these vulnerable children, this study explores the predictive relationship between the utilization of perinatal health services and birth certificate… (More)

Model uncertainty is pervasive in social science. A key question is how robust empirical results are to sensible changes in model specification. We present a new approach and applied statistical software for computational multi-model analysis. Our approach proceeds in two steps: First, we estimate the modeling distribution of estimates across all… (More)
Economic sociologists agree that economic rationality is constructed and that morality and economic interests often intersect. Yet we know little about how Americans organize their economic beliefs or assess the morality of markets. We distinguish position taking (how people respond to opinion items) from construal (how respondents understand and structure… (More)
