This study explored how experts and novices in pedagogics expanded queries supported by the ERIC thesaurus, and how this was connected to the search success in an easy and a difficult search task. The expert group consisted of 15 undergraduates in pedagogy and the novice group of 15 students with no studies in this field. Their search logs were recorded and a preand post-search interview was co...

BACKGROUND Financial abuse of elders is an under acknowledged problem and professionals' judgements contribute to both the prevalence of abuse and the ability to prevent and intervene. In the absence of a definitive "gold standard" for the judgement, it is desirable to try and bring novice professionals' judgemental risk thresholds to the level of competent professionals as quickly and effectiv...

This study aimed to examine the level of shooting accuracy demonstrated by law enforcement recruits upon completion of their law enforcement firearms training in comparison with novice shooters. One hundred and ninety-five male and 52 female law enforcement recruits volunteered. Participants were separated by firearms experience into the following groups: expert (completed law enforcement firea...

We study parametric amplification in nonlinear left-handed transmission lines, which serve as model systems for nonlinear negative-index metamaterials. We experimentally demonstrate the amplification of a weak signal in the three following regimes: with the signal in the left-handed band, with the signal in the stop band, and with the signal at a defect frequency. In particular, we demonstrate ...

The vasodilator-stimulated phosphoprotein (VASP) is a key regulator of actin dynamics. We have determined the 1.3-A resolution crystal structure of the 45-residue-long tetramerization domain (TD) from human VASP. This domain forms a right-handed alpha-helical coiled-coil structure with a similar degree of supercoiling as found in the widespread left-handed coiled coils with heptad repeats. The ...

Experts and intermediates fundamentally differ in the ways they explain subject matter to novices. Experts provide less details but in a highly coherent format, whereas intermediates provide many additional details but in a format with low coherency. In a recent study, we found that experts’ explanations enabled novices to acquire more transferable and flexible knowledge as opposed to explanati...
