Tilt and Multitouch Input for Tablet Play of Real-Time Strategy Games

We are studying the use of tilt-enabled handheld touchscreen devices as an interface for top-down strategy games. We will explore how using different input modes (tilt and touch) compare for certain tasks in terms of efficiency and comfort. Real-time and turn-based strategy games are a popular form of electronic gaming, though these games currently have only minor representation on tablets. This genre of game requires both a wide variety of input and the display of a wealth of information. We are exploring whether, with suitable interface developments, this genre can become as accessible on tablet devices as on traditional computers. These interface approaches may also prove useful for expanding the presence of other game genres in the mobile space

The Journal of The Experimental Analysis of Behavior at Zero, Fifty, and One Hundred

The experimental content areas represented in JEAB in its first volume (1958) and 50 years later in Volume 87 are in many ways similar with regard to research on schedules of reinforcement, research with human subjects, and several other topics. Experimental analysis has not been displaced by quantitative analysis. Much less research on aversive control has been published in recent than in earlier years. Wishes for progress in the next 50 years include experiments on verbal behavior, the sources of novel behavior, and observing responses based on stimuli correlated with escape or avoidance

Designing Biobased Recyclable Polymers for Plastics

Several concurrent developments are shaping the future of plastics. A transition to a sustainable plastics system requires not only a shift to fossil-free feedstock and energy to produce the carbon-neutral building blocks for polymers used in plastics, but also a rational design of the polymers with both desired material properties for functionality and features facilitating their recyclability. Biotechnology has an important role in producing polymer building blocks from renewable feedstocks, and also shows potential for recycling of polymers. Here, we present strategies for improving the performance and recyclability of the polymers, for enhancing degradability to monomers, and for improving chemical recyclability by designing polymers with different chemical functionalities
