Cichlid fish inhabit a diverse range of environments that vary in the spectral content of light available for vision. These differences should result in adaptive selective pressure on the genes involved in visual sensitivity, the opsin genes. This study examines the evidence for differential adaptive molecular evolution in East African cichlid opsin genes(More)

n contemporary society, scientists hold a considerable degree of respect, trust, admiration, and authority. Surveys show that North American and European citizens hold a deep belief in the promise of science to solve problems, as well as to improve quality of life and the on controversial topics such as climate change, many Americans believe scientists have(More)
H ave you ever asked your students the following questions: Why do we need oxygen? How does it get into our cells? How do ecosystems maintain their balance? What are the roles of different organ-isms? All of these questions focus on systems thinking and are useful in helping to push students to think below the surface. Systems thinking is so important that(More)
!! Understanding complex systems is a difficult but important component of scientific literacy (Sabelli, 2006). !! SBF is a conceptual representation for reasoning about multiple complex systems. !! Two lenses for studying transfer-Actor-oriented approach: traces trajectories adopted by the learner to see similarities between two situations (Lobato, 2006).(More)
The benefits and side effects of electroconvulsive therapy (ECT) given two vs. three times per week were examined in depressed inpatients. Twenty subjects were randomly assigned to one of two treatment conditions (unilateral ECT two or three times weekly). Examiners without knowledge of treatment condition rated depression and psychiatric status and(More)
The core problem we address in this paper is how to take a declarative conceptual representation of a complex system and produce an agent-based simulation of that model. In particular, we describe a computational technique that takes Structure-Behavior-Function models of complex systems and simulates the behavior of the modeled system in NetLogo, an(More)
Citizen science can make major contributions to informal science education by targeting participants' attitudes and knowledge about science while changing human behavior towards the environment. We examined how training associated with an invasive species citizen science program affected participants in these areas. We found no changes in science literacy(More)
