Quick, but Not Dirty: The Usefulness of Flash Mob Studies as a Method for Action Research in eHealth by Kira Oberschmidt, Christiane Grünloh, Stephanie Jansen-Kosterink, Monique Tabak

“…Outcomes show that the flash mob is a potential method for AR, as it is situated in a practical setting where stakeholders can easily be involved, and its pace could speed up the AR cycles. To further improve the applicability for AR, our main recommendations include: promoting the flash mob adequately to increase participation and improve the involvement of 'champions'; tracking interactions outside the flash mob (e.g., comments and questions from bystanders); and choosing an accessible and visible location, taking into account the activities associated with the location.…”

Investigation on Dynamic Factors of Railway Steel-Plate–Concrete Composite Beam Bridges With Small and Medium Spans by Jin Di, Yi Su, Yuxuan Han, Jinming Luo, Fengjiang Qin, Rui Yan

“…Dynamic factor (DF) is an important indicator for describing the dynamic action of a train on a bridge. For small- and medium-span bridges, although existing research and codes have studied and specified the DF of steel–concrete composite beam bridges, few studies have been refined to steel-plate–concrete composite beam bridges (SPCCBs), and the effect of eccentric loads has not been considered. …”

Experimental study on pore structure and dynamic mechanical properties of modified rubber concrete after freeze-thaw cycle by Minggao Chen, Shujie Yang, Shuyuan Wang, Yan Zhou

“…The elastic action of rubber particles can reduce the increase of the internal porosity of concrete under the action of freeze-thaw cycles and reduce the internal porosity of concrete materials. (3) The peak stress and dissipated energy of three kinds of concrete specimens decreased linearly due to freeze-thaw cycle, and the decrease of plain concrete was higher than that of modified rubber concrete. …”

Feasibility of a Non-Anticipatory, Random-Action Target System to Improve Shooting Performance: A Brief Field Trial by Matthew Lee Smith, Ali Boolani

“…Observational data were gathered from a single-day, three-round trial to test shooting accuracy and shooting errors when shooters were unable to anticipate target appearance location and target exposure speed. In Trial 1, the target exposure time was 0.5 s, which increased to 0.7 s in Trial 2, and decreased back to 0.5 s in Trial 3. …”
