1. There is great interest on the effects of habitat fragmentation, whereby habitat is lost and the spatial configuration of remaining habitat patches is altered, on individual breeding performance. However, we still lack consensus of how this important process affects reproductive success, and whether its effects are mainly due to reduced fecundity or nestling survival. 2. The main reason for ...

The study tested the application of structural equation modelling (SEM) to ubiquitous learning of selected Zimbabwean schools. The purpose of this study was to explore the effect of diffusion factors toward ubiquitous learning in Zimbabwe. The main hypothesis being tested was: “ ICT facilities have a positive effect on the diffusion and adoption of ubiquitous learning in Zimbabwean schools”. Th...

Twin studies are important to investigate genetic influences on variation in human brain morphology in health and disease. However, the twin method has been criticized for its alleged non-generalizability due to differences in the intrauterine and family environment of twins, compared with singletons. To test whether twin-singleton differences complicate interpretation of genetic contributions ...

The following paper presents current thinking and research on fit indices for structural equation modelling. The paper presents a selection of fit indices that are widely regarded as the most informative indices available to researchers. As well as outlining each of these indices, guidelines are presented on their use. The paper also provides reporting strategies of these indices and concludes ...
