Depictions of scientific development in popular media carry significant influence over the way that the public envisions science as a process and as an institution. One such popular depiction of science is the “Tech Tree,” a common game mechanic in strategy videogames. This mechanic is often problematic, as in its most common form, the tech tree depicts a technologically deterministic view of s...

Three experiments explore how American (N = 102) and Egyptian (N = 73) preschoolers’ inferences about expertise are affected by an expert’s gender and occupation. Children viewed a nurse and a car mechanic in a gender stereotypical (female nurse, male mechanic) or counterstereotypical (female mechanic, male nurse) presentation and indicated who would know more about profession-related informati...

This study documents age trends, interrelations, and correlates of intellectual abilities in old and very old age (70-103 years) from the Berlin Aging Study (N = 516). Fourteen tests were used to assess 5 abilities: reasoning, memory, and perceptual speed from the mechanic (broad fluid) domain and knowledge and fluency from the pragmatic (broad crystallized) domain. Intellectual abilities had n...

Results He had Type II A aortic dissection with intimal tear at proximal region of the right coronary ostium. Mechanic aortic valve was normal function. Ascending aorta was replaced by using 26 mm Dacron tube graft between annulus of previous mechanic aortic valve and distal ascending aort by using hypothermic circulatory arrest and antegrade selective cerebral perfusion. An 8 mm dacron tube gr...

Taking into account the results that we have been obtained during the last decade in the foundations of quantum mechanic we put forward a view on reality that we call the ‘creation discovery view’. In this view it is made explicit that a measurement is an act of a macroscopic physical entity on a microphysical entity that entails the creation of new elements of reality as well as the detection ...

Level creation is a creative game-play exercise that resembles problem-posing, and has shown to be engaging and helpful for players to learn about the game’s core mechanic. However, in user-authoring environments, users often create levels without considering the game’s objective, or with entirely different objectives in mind, resulting in levels which fail to afford the core gameplay mechanic....

Cognitive gameplay—the cognitive dimension of a player’s experience—emerges from the interaction between a player and a game. While its design requires careful consideration, cognitive gameplay can be designed only indirectly via the design of game components. In this paper, we focus on one such component—the core mechanic—which binds a player and game together through the performance of essent...

The comparison of form factors calculated from a single-particle current in different relativistic quantum mechanic approaches evidences tremendous discrepancies. The role of constraints coming from space-time translations is considered here with this respect. It is known that invariance under these translations implies the energy-momentum conservation relation that is usually assumed to hold g...

This article describes a rare, however extremely pleasing, scientific study originated by Prof. Louis Massa during a friendly discussion, which yielded an insightful understanding of one of the two major ribosome functions, namely peptide bond formation. It demonstrates how elaborate, creative approach to the investigation of the location of the actual reaction of the formation of peptide bonds...
