Estimating the reproducibility of psychological science

Abstract: Reproducibility is a defining feature of science, but the extent to which it characterizes current research is unknown. We conducted replications of 100 experimental and correlational studies published in three psychology journals using high-powered designs and original materials when available. Replication effects were half the magnitude of original effects, representing a substantial decline. Ninety-seven percent of original studies had statistically significant results. Thirty-six percent of replications had statistically significant results; 47% of original effect sizes were in the 95% confidence interval of the replication effect size; 39% of effects were subjectively rated to have replicated the original result; and if no bias in original results is assumed, combining original and replication results left 68% with statistically significant effects. Correlational tests suggest that replication success was better predicted by the strength of original evidence than by characteristics of the original and replication teams.

The Self-Efficacy Scale: Construction and Validation:

Abstract: Self-efficacy theory asserts that personal mastery expectations are the primary determinants of behavioral change. Further, it is suggested that individual differences in past experiences and attri...

The Sorghum bicolor genome and the diversification of grasses

Abstract: Sorghum, an African grass related to sugar cane and maize, is grown for food, feed, fibre and fuel. We present an initial analysis of the approximately 730-megabase Sorghum bicolor (L.) Moench genome, placing approximately 98% of genes in their chromosomal context using whole-genome shotgun sequence validated by genetic, physical and syntenic information. Genetic recombination is largely confined to about one-third of the sorghum genome with gene order and density similar to those of rice. Retrotransposon accumulation in recombinationally recalcitrant heterochromatin explains the approximately 75% larger genome size of sorghum compared with rice. Although gene and repetitive DNA distributions have been preserved since palaeopolyploidization approximately 70 million years ago, most duplicated gene sets lost one member before the sorghum-rice divergence. Concerted evolution makes one duplicated chromosomal segment appear to be only a few million years old. About 24% of genes are grass-specific and 7% are sorghum-specific. Recent gene and microRNA duplications may contribute to sorghum's drought tolerance.

Using MPI: Portable Parallel Programming with the Message-Passing Interface

Abstract: This book offers a thoroughly updated guide to the MPI (Message-Passing Interface) standard library for writing programs for parallel computers Since the publication of the previous edition of Using MPI, parallel computing has become mainstream Today, applications run on computers with millions of processors; multiple processors sharing memory and multicore processors with multiple hardware threads per core are common The MPI-3 Forum recently brought the MPI standard up to date with respect to developments in hardware capabilities, core language evolution, the needs of applications, and experience gained over the years by vendors, implementers, and users This third edition of Using MPI reflects these changes in both text and example code The book takes an informal, tutorial approach, introducing each concept through easy-to-understand examples, including actual code in C and Fortran Topics include using MPI in simple programs, virtual topologies, MPI datatypes, parallel libraries, and a comparison of MPI with sockets For the third edition, example code has been brought up to date; applications have been updated; and references reflect the recent attention MPI has received in the literature A companion volume, Using Advanced MPI, covers more advanced topics, including hybrid programming and coping with large data
