Agent-based modelling has become an increasingly important tool for scholars studying social and social-ecological systems, but there are no community standards on describing, implementing, testing and teaching these tools. This paper reports on the establishment of the Open Agent-Based Modelling Consortium,, a community effort to foster the(More)
Geographically distributed workgroups are increasingly collaborating on time-sensitive, highly interdependent tasks that require detailed coordination to achieve success; although success under these conditions is often difficult. Improving these collaborations requires both better support from communication and information tools and a better understanding(More)
Experimental data from a spatially explicit dynamic commons dilemma experiment is used to empirically ground an agent-based model. Four distinct patterns are identified in the data. Two naïve models, random walk and greedy agents, do not match the patterns. A more comprehensive model is presented that explains how agents make movement and harvest decisions.(More)
In traditional public good experiments participants receive an endowment from the experimenter that can be invested in a public good or kept in a private account. In this paper we present an experimental environment where participants can invest time during five days to contribute to a public good. Participants can make contributions to a linear public good(More)
OBJECTIVE To evaluate head, pelvic, and limb movement to detect lameness in galloping horses. ANIMALS 12 Thoroughbreds. PROCEDURES Movement data were collected with inertial sensors mounted on the head, pelvis, and limbs of horses trotting and galloping in a straight line before and after induction of forelimb and hind limb lameness by use of sole pressure.(More)

Mammalian cerebral cortex is accepted as being critical for voluntary motor control, but what functions depend on cortex is still unclear. Here we used rapid, reversible optogenetic inhibition to test the role of cortex during a head-fixed task in which mice reach, grab, and eat a food pellet. Sudden cortical inhibition blocked initiation or froze execution(More)
BACKGROUND Successful microarray experimentation requires a complex interplay between the slide chemistry, the printing pins, the nucleic acid probes and targets, and the hybridization milieu. Optimization of these parameters and a careful evaluation of emerging slide chemistries are a prerequisite to any large scale array fabrication effort. We have(More)
