Border Patrol: The Rise and Role of Fact-Checkers and Their Challenge to Journalists’ Normative Boundaries

Although most research to date has focused on leading U.S. fact-checkers, similar initiatives are gaining strength all over the world. This study draws on a globally disseminated questionnaire, plus interviews with fact-checkers on four continents, to examine their role and reach in relation to other journalistic enterprises, as well as the challenges they face. A conceptual framework of journalistic boundary-setting helps guide the exploration

Oscillations and traveling waves of calcium: a simplified model

We construct a heuristic model of calcium oscillations in pancreatic acinar cells. The model is based on the two-state model of Sneyd et al. (Sneyd, J., A. LeBeau and D. Yule, 2000, Traveling waves of calcium in pancreatic acinar cells: model construction and bifurcation analysis, Physica D, in press) and is similar in spirit to the FitzHugh reduction of the Hodgkin-Huxley equations. The simpli¯ed model successfully reproduces the oscillatory behavior and wave behaviour of the more complex model. In particular, the simpli¯ed model provides an example of a simple, physiologically relevant model that has a T-point and an associated spiral branch of homoclinic orbits
