This review surveys recent achievements of molecular computer modeling in understanding spatial structure, dynamics, and mechanisms of functioning of transmembrane α-helical dimers in membranes.
Papanastasiou (2003) and Papanastasiou et al. (2005) found that computer use does not have a positive nor negative effect on students' science achievement based on PISA results, but the way of computer use affects science achievement.
But recent achievements have impressed a wide spectrum of computer experts.
Although simple OLS estimates might not yield a causal effect because the scholastic achievements of students and the use of computer technology might correlate with unobservable factors (i.e., good teachers use technologies, which might not be causally related to the outcomes).
This brief review of the empirical literature of effects of home computer use on student achievement shows a mixture of positive, negative, and null effects of computer use on academic achievement.
There is also another reason to include these student characteristics in the model; namely, to investigate possible interaction effects with respect to reading achievement between student characteristics and frequency of computer use.
By using this instrument, the authors estimated that the causal effect of computer usage on student achievements did not significantly differ from zero.
As has already been mentioned the plausible values for reading achievement were divided by 100, and the measure of computer use was expressed as the proportion of students saying they were using computers at least once or twice a week.
In the current study we investigated effects of computer use at home on reading achievement, using longitudinal data at the country level.
It's a kind of "revenge of the nerds" - a dry run for the more spectacular achievements of Bill Gates and Steve Jobs, of superstar DJs and computer game tycoons.
The life and achievements of Alan Turing - the mathematician, codebreaker, computer pioneer, artificial intelligence theoretician, and gay/cultural icon - are being celebrated to mark what would have been his 100th birthday on 23 June.
