Mobile learning anytime, anywhere: What are our students doing?

Recent developments in mobile technologies have provided unique opportunities for learning and teaching. This paper reports on recent research undertaken at a regional Australian university in order to understand how higher education students are using mobile devices to support their learning. A survey instrument was developed and deployed and the data collected analysed quantitatively. Upon an...

Doing our best: optimization and the management of risk.

Tools and concepts of optimization are widespread in decision-making, design, and planning. There is a moral imperative to "do our best." Optimization underlies theories in physics and biology, and economic theories often presume that economic agents are optimizers. We argue that in decisions under uncertainty, what should be optimized is robustness rather than performance. We discuss the equit...

The Pif1 family in prokaryotes: what are our helicases doing in your bacteria?

Pif1 family helicases, which are found in nearly all eukaryotes, have important roles in both nuclear and mitochondrial genome maintenance. Recently, the increasing availability of genome sequences has revealed that Pif1 helicases are also widely found in diverse prokaryotes, but it is currently unknown what physiological function(s) prokaryotic Pif1 helicases might perform. This Perspective ai...
