Pre-service elementary teachers' motivations to become a teacher and its relationship with teaching self-efficacy
(ELSEVIER SCIENCE BV, SARA BURGERHARTSTRAAT 25, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2014)This study investigated 341 pre-service elementary teachers' motives to become a teacher using Factors Influencing Teaching Choice (FIT-Choice) theory as a basis. It then investigated how these motivations change as ... -
HomSI: a homozygous stretch identifier from next-generation sequencing data
(OXFORD UNIV PRESS, GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND, 2014)In consanguineous families, as a result of inheriting the same genomic segments through both parents, the individuals have stretches of their genomes that are homozygous. This situation leads to the prevalence of recessive ... -
