Imagining projective transformations: aligned orientations in spatial organization
Article Abstract:
The parallel and perpendicular aligned orientations in spatial organization improve the ability to imagine projective transformations and provide redundancy. These orientations are categorically single and distinct. The imagination of spatial structures and transformations depends on the basic properties of spatial organization, and their interaction with memory, attention and problem solving. Proper alignment among the different structural components helps in efficient imagination.

Cigarette smoking among schoolboys in Beijing, China
Article Abstract:
A study of 323 middle school pupils showed that boys were more likely to smoke than girls and the incidence of smoking increased as they got older. Around 15% of the group had smoked. Those with behaviour problems, low academic achievement at school and peers who smoked were also more likely to smoke. Being more physically developed was also a factor. The education level of parents was not significant.
