FROM THE CLASSICS TO TODAY: HOW MUCH HAVE VALUES CHANGED?

The classic novels offer wonderful insight into some of the dominant cultural values of pre-modern China. They portray values indirectly through character and narrative rather than through explicit identification, and they usually tell us which values are preferred or honored by the society and which are condemned, without telling us how widespread a particular set of values was, or which sectors of society tended to hold which values. An alternative approach to studying cultural values is the social science method of survey research, which allows us to measure cultural values directly and to describe culture as a quantitative distribution of values across a population. Of course survey research cannot go back in history to measure the distribution of values in the past. But if we compare the values presented qualitatively in classical literature with those described quantitatively in modern survey research, we can get some sense of the extent to which values have stayed the same or have changed since pre-modern times

Simon-Task Reveals Balanced Visuomotor Control in Experienced Video-Game Players

Both short and long-term video-game play may result in superior performance on visual and attentional tasks. To further these findings, we compared the performance of experienced male video-game players (VGPs) and non-VGPs on a Simon-task. Experienced-VGPs began playing before the age of 10, had a minimum of 8 years of experience and a minimum play time of over 20 h per week over the past 6 months. Our results reveal a significantly reduced Simon-effect in experienced-VGPs relative to non-VGPs. However, this was true only for the right-responses, which typically show a greater Simon-effect than left-responses. In addition, experienced-VGPs demonstrated significantly quicker reaction times and more balanced left-versus-right-hand performance than non-VGPs. Our results suggest that experienced-VGPs can resolve response-selection conflicts more rapidly for right-responses than non-VGPs, and this may in part be underpinned by improved bimanual motor control

Hydrogen-silicon carbide interactions

A study of the thermochemistry and kinetics of hydrogen environmental attack of silicon carbide was conducted for temperatures in the range from 1100 C to 1400 C. Thermodynamic maps based on the parameters of pressure and oxygen/moisture content were constructed. With increasing moisture levels, four distinct regions of attack were identified. Each region is defined by the thermodynamically stable solid phases. The theoretically stable solid phases of Region 1 are silicon carbide and silicon. Experimental evidence is provided to support this thermodynamic prediction. Silicon carbide is the single stable solid phase in Region 2. Active attack of the silicon carbide in this region occurs by the formation of gases of SiO, CO, CH4, SiH4, and SiH. Analysis of the kinetics of reaction for Region 2 at 1300 C show the attack of the silicon carbide to be controlled by gas phase diffusion of H2O to the sample. Silicon carbide and silica are the stable phases common to Regions 3 and 4. These two regions are characterized by the passive oxidation of silicon carbide and formation of a protective silica layer
