In this study, 126 children were observed at 6 months, 12 months, and 2 years. During infancy, latencies to reach for novel objects were measured. At 2 years, positive and negative affect, and behavioral approach-inhibition to low- and high-intensity situations were coded, and mothers assessed behavior problems. Confirmatory factor analysis indicated a 3-dimension model of positivity, negativit...

let r be an associative ring with identity, c(r) be the category of com-plexes of r-modules and flat(c(r)) be the class of all at complexes of r-modules. we show that the at cotorsion theory (flat(c(r)); flat(c(r))−)have enough injectives in c(r). as an application, we prove that for each atcomplex f and each complex y of r-modules, exti (f,x)= 0, whenever ris n-perfect and i > n.

A novel approach is proposed for automated dimension estimation in memory polynomial based power amplifiers/transmitters behavioral models. This method consists of successively identifying the static nonlinearity order and memory depth of the model in accordance with a predefined performance criterion. The proposed method is validated using a 3G Doherty power amplifier driven by various WCDMA s...

The recent dramatic and interesting advances in computer technology have significantly altered the roles of both users and developers. Role theory might be applied to more fully understand and more effectively investigate organizational, behavioral, and social issues related to these changes. A framework for categorizing information systems roles is built from a matrix of information system and...
