Media Matter: But "Old" Media May Matter More Than "New" Media.

Why Media Matter Media Effectiveness from a Performance Perspective

The subject of media influences on learning is revisited in this article. Whether instructional outcomes can be attributed to media, methods, or both has been debated since Clark (1983) asserted that there is no evidence supporting learning benefits from the use of any specific medium. Kozma (1991, 1994a, 1994b) challenged Clark’s claim that only methods affect learning and others took up the d...

Do Social Media Matter? Initial Empirical Evidence

Natural Resource Governance: Does Social Media Matter?

In this paper we study the relationship between communication and ”transparency of information” and governance by exploring the link between social media and natural resource governance. Using a cross-country analysis, we document a robust and statistically significant positive relationship between Facebook penetration (a proxy for social media) and natural resource governance. It follows that ...

Avalanche Dynamics for Active Matter in Heterogeneous Media

Using numerical simulations, we examine the dynamics of active matter run-and-tumble disks moving in a disordered array of obstacles. As a function of increasing active disk density and activity, we find a transition from a completely clogged state to a continuous flowing phase, and in the large activity limit, we observe an intermittent state where the motion occurs in avalanches that are powe...
