Self-determination theory research has demonstrated that intrinsic and identified self-regulations are associated with successful adaptation. However, few distinctions are typically made between these regulations and their outcomes. In the present studies, the associations between intrinsic and identified motivations and outcomes of psychological well-being and academic performance are compared...
In this article we focus on time-to-event studies with a randomised treatment assignment that may be compromised by selective compliance. Contrary to most of the extensive literature on evaluation studies we do not consider the effect of the treatment on some average outcome but on the hazard rate. In time-to-event studies the treatment may vary over time. Another complication of duration data ...

abstract background: although cyclosporine (csa) and calcium channel blockers (ccbs) parallel to each other may provoke gingival enlargement (ge), there are few considerations about combined effects of csa and ccbs on gingival tissues. objectives: this study aimed to determine prevalence of ge among renal transplant recipients and to compare its occurrence in patients who received only csa and ...
Two trials were conducted to study the effect of multi-steps phase-feeding (PF) program on growth performance of broiler chickens from 1 to 24 and 1 to 39 d of age. The control group was the nutrient recommendation of Aviagen (2019) with a three-step PF program (1-10, 11-24 and 25-39 d of age). In the first trial, the control group was compared with an eight-step PF program (PF8), and in the se...
The current tendency is to provide post-approval evidence from separate, often larger and less well controlled trials. Typical examples of these are pragmatic trials (randomisation, little/no control), purely prospective observational trials (no randomisation, no control) and use of historic controls. #3 New study design: Mixed RCT (cont.) In a Mixed RCT patients would be selected and randomise...
Recent models have suggested an important role for neuromodulation in explaining trial-to-trial adaptations in cognitive control. The adaptation-by-binding model (Verguts & Notebaert, Psychological review, 115(2), 518-525, 2008), for instance, suggests that increased cognitive control in response to conflict (e.g., incongruent flanker stimulus) is the result of stronger binding of stimulus, act...
