Introduction: The depth jump (DJ) and squat (SJ) are accepted ways to assess train power producing ability but not without risk of injury. Methods: Sixteen male participants (age = 21.7 ± 1.54 yrs., height 177.7 11.4 cm, mass 77.7 13.6 kg) were evaluated for exertion capabilities while being assessed injury in the knee low back through a range resistances based on percentage participants’ heigh...

PURPOSE To determine whether the magnitude of performance improvements and the mechanisms driving adaptation to ballistic power training differ between strong and weak individuals. METHODS Twenty-four men were divided into three groups on the basis of their strength level: stronger (n = 8, one-repetition maximum-to-body mass ratio (1RM/BM) = 1.97 +/- 0.08), weaker (n = 8, 1RM/BM = 1.32 +/- 0....

The gaze behaviour of riders during their approach to a jump was investigated using a mobile eye tracking device (ASL Mobile Eye). The timing, frequency and duration of fixations on the jump and the percentage of time when their point of gaze (POG) was located elsewhere were assessed. Fixations were identified when the POG remained on the jump for 100 ms or longer. The jumping skill of experien...

This study’s purpose was to compare jump height, velocity and force production between video simulated blocking, [reactive timing (RT) jump], and maximal effort vertical jumping, [self-select timing (SST) jump]. 10 female collegiate volleyball players performed both jumps onto a force plate in a laboratory while being videotaped with one camera. Jump heights(cm), velocities(m/s), and forces(%BW...

Abstract – The Dynamic Field Theory (DFT) has been used to account for spatial recall biases in children and adults. This paper extends the DFT to a second spatial working memory task, position discrimination. The DFT captures details of adults’ discrimination performance, as well as predicting developm...

We develop and experimentally test a model of bidder behavior in a simultaneous ascending auction for heterogeneous common value goods. The model follows the ‘straightforward’ strategy developed by Milgrom (2000) while accounting for the adverse selection effect and the potential for the winner’s curse. When this model is evaluated against laboratory results we find that bidders deviate from th...

We present a summary of the lectures delivered to the Institute for Mathematical Sciences, Singapore, during the 2005 Summer School in Mathematical Logic. The lectures covered topics on the global structure of the Turing degrees D, the countability of its automorphism group, and the definability of the Turing jump within D.

The article presents a new technique for metamorphic viruses detection based on the search of equivalent functional blocks. The method takes into account the obfuscation techniques of blocks reordering. The method involves the searching of the correspondences between the functional blocks of the metamorphic versions, and consists of two stages. On the first stage the equivalent functional block...

We run a large field experiment with an online company specializing in selling used automobiles via ascending auctions. We manipulate experimentally the maximum amount which bidders can bid above the current standing price, thus affecting the ease with which bidders can engage in jump bidding. We test between the intimidation vs. costly bidding hypotheses of jump bidding by looking at the effec...
