Sensing and visualizing spatial relations of mobile devices

Location information can be used to enhance interaction with mobile devices. While many location systems require instrumentation of the environment, we present a system that allows devices to measure their spatial relations in a true peer-to-peer fashion. The system is based on custom sensor hardware implemented as USB dongle, and computes spatial relations in real-time. In extension of this system we propose a set of spatialized widgets for incorporation of spatial relations in the user interface. The use of these widgets is illustrated in a number of applications, showing how spatial relations can be employed to support and streamline interaction with mobile devices

The Moderating Role of PBS in the Relationship Between Positive Expectancies and Alcohol-Related Negative Consequences

Hazardous drinking college students have become an increasingly focused upon group within alcohol research, especially considering the extent of negative consequences they experience. Recently, increased positive expectancies has been identified as an influential contributor to increased hazardous drinking and alcohol-related negative consequences. However, more comprehensive evaluation of the domains of positive expectancies (e.g., sociability, tension reduction, sexual enhancement, liquid courage) is warranted to ascertain which types are more salient in predicting hazardous drinking and alcohol-related negative consequences. Further, research has yet to explore how protective behavioral strategies (PBS) affect the strength of the associations between specific positive expectancies and alcohol-related negative consequences. Therefore, the goal of the present study was to investigate the moderating role of PBS in the relationship between the domains of positive expectancies and alcohol-related negative consequences in a sample of hazardous drinking college students. Using moderated multiple regression, significant positive associations were observed for liquid courage and sexual enhancement positive expectancies whereas an inverse association for PBS-Serious Harm Reduction (SHR) emerged. But, no moderating effects for PBS were found in any of the analyses. These results suggest that liquid courage and sexual enhancement positive expectancies may be more salient in predicting alcohol-related negative consequences. Clinical and empirical implication, limitations, and future research directions are discussed

Development of new addition-type composite resins

The most promising of a number of new addition type polyimides and polyaromatic melamine (NCNS) resins for use in high performance composite materials. Three different cure temperature ranges were of interest: 530-560 K (500-550 F), 475-530 K (400-500 F), and 450 K (350 F). Examined were a wide variety of polyimide precursors terminated with 5 norbornene groups and addition polymerized at 560 K similar to PMR-15 and LARC-160 polyimides. In addition, a number of lower curing cinnamal end capped polyimides and a bismaleimide were investigated but were not found promising. A group of NCNS resins were investigated and some were found to be superior to current epoxy resins in moisture resistance, oxidative aging and flame and smoke properties

Effects of prediction error on episodic memory retrieval: evidence from sentence reading and word recognition

Prediction facilitates word processing in the moment, but the longer-term consequences of prediction remain unclear. We investigated whether prediction error during language encoding enhances memory for words later on. German-speaking participants read sentences in which the gender marking of the pre-nominal article was consistent or inconsistent with the predictable noun. During subsequent word recognition, we probed participants’ recognition memory for predictable and unpredictable nouns. Our results indicate that individuals who demonstrated early prediction error during sentence reading, showed enhanced recognition memory for nouns overall. Results from an exploratory step-wise regression showed that prenominal prediction error and general reading speed were the best proxies for recognition memory. Hence, prediction error may facilitate recognition by furnishing memory traces built during initial reading of the sentences. Results are discussed in the light of hypotheses positing that predictable words show a memory disadvantage because they are processed less thoroughly
