We report the transmission coefficient for different positions of transmission and incidence terminals. The investigated results show that both transmission coefficient and spin-polarized efficiency were periodic oscillations with increasing semiconductor ring sizes, which depended on the changes of transmission terminals positions. The different effects of the ferromagnetic electrode, Rashba spin-orbit coupling and applied magnetic field on spin-polarized efficiency and transmission coefficient were also considered. The tunneling coefficient decreases monotonically with the δ barrier strength, while spin-polarized efficiency increased with the δ barrier strength. Source

Future of Children | Year: 2014

Most of the authors in this issue of Future of Children focus on a single strategy for helping both adults and children that could become a component of two-generation programs. Lindsay Chase-Lansdale and Jeanne Brooks-Gunn, on the other hand, look at actual programs with an explicit two-generation focus that have been tried in the past or are currently under way. These explicitly two-generation programs have sought to build human capital across generations by combining education or job training for adults with early childhood education for their children. Chase-Lansdale and Brooks-Gunn explain the theories behind these programs and review the evidence for their efficacy. A first wave of such programs in the 1980s and 1990s produced mostly disappointing results, but the evaluations they left behind pointed to promising new directions. More recently, a second wave of two-generation programs-the authors dub them "Two-Generation 2.0"-has sought to rectify the flaws of earlier efforts, largely by building strong connections between components for children and adults, by ensuring that children and adults receive services of equal duration and intensity, and by incorporating advances in both education and workforce development. These Two-Generation 2.0 programs are still in their infancy, and we have yet to see clear evidence that they can achieve their goals or be implemented cost-effectively at scale. Nonetheless, Chase-Lansdale and Brooks-Gunn write, the theoretical justification for these programs is strong, their early results are promising, and the time is ripe for innovation, experimentation, and further study.

Data from the NICHD Study of Early Child Care and Youth Development (N = 723) were used to test whether the effects of fathers' supportive parenting on children's school readiness are greater when mothers are least supportive. We distinguished between academic and social dimensions of school readiness. Mothers' and fathers' parenting was assessed in dyadic parent-child videotaped sessions during the preschool period. Results for both academic and social outcomes indicated that fathers' supportiveness had larger benefits for children at lower levels of mothers' supportiveness. In fact, fathers' supportiveness was associated with children's school readiness only when mothers scored average or below on supportiveness. Mothers' supportiveness was similarly associated with children's social school readiness when fathers scored average or below on supportiveness. However, mothers' supportiveness was associated with children's academic school readiness even when fathers scored above average on supportiveness. The results suggest that fathers may influence child development most as potential buffers against unsupportive mother parenting. Further research is needed to replicate these analyses in a less socioeconomically advantaged sample. 2010 APA, all rights reserved Source

Background: The juvenile justice system's interventions are expected to help reduce recidivism. However, previous studies suggest that official processing in juvenile court fails to reduce adolescents' criminal behavior in the following year. Longer term effects have not yet been investigated with a rigorous method. This study used propensity score matching to assess the impact of juvenile court processing into young adulthood. Method: Participants were part of a prospective longitudinal study of 1,037 boys from low- socioeconomic areas of Montreal, followed from ages 6-25 years. During their adolescence, 176 participants were processed in juvenile court, whereas 225 were arrested, but not sent to court. Propensity score matching was used to balance the group of participants exposed to juvenile court and the unexposed comparison group on 14 preadolescent child, family and peer characteristics. The two groups were compared on their official adult criminal outcomes. Results: The risk of conviction for an adult offence was 50.0% for court-processed participants compared with 24.3% for their matched counterparts, OR = 3.13, 95% CI = 1.80-5.44. Court-processed participants committed an average of 0.39 violent crimes, compared with 0.15 for their matched counterparts; Poisson model IRR = 2.60, 95% CI = 1.39-4.87. They also committed an average of 2.38 nonviolent crimes, compared to 1.30 for their matched counterparts, IRR = 1.87, 95% CI = 1.19-2.93. Conclusions: Rather than decreasing recidivism, juvenile court intervention increased both violent and nonviolent future crimes. Along with previous studies, this study highlights a pressing need for more research and knowledge transfer about effective interventions to reduce recidivism among youths who commit crime. © 2012 The Authors.

Motion estimation is the process of selecting an offset to a suitable reference area in a previously coded frame. In this paper, the Predictive Motion Vector Field Adaptive Search Technique (PMVFAST) and Enhanced-PMVFAST (EPMVFAST) algorithm was reviewed, and we studied in detail the motion estimation technology in AVS in two parts: soft and hard decision process in motion estimation, soft-decision based local search pattern. ©2010 IEEE.
