USING THE MANY-FACET RASCH MODEL TO ANALYSE AND EVALUATE THE QUALITY OF OBJECTIVE STRUCTURED CLINICAL EXAMINATION: A NON-EXPERIMENTAL CROSS-SECTIONAL DESIGN

Objectives Sources of bias, such as the examiners, domains and stations, can influence the student marks in objective structured clinical examination (OSCE).This study describes the extent to which the facets modelled in an OSCE can contribute to scoring variance and how they fit into a Many-Facet Rasch Model (MFRM) of OSCE performance.A further ob

Objectives Tuberculosis (TB) remains prevalent despite the availability of effective anti-TB medications, and accumulating evidence suggests a high rate of mental disorders in people with TB.This is because TB and psychiatric disorders share several risk factors, such as poverty, homelessness and substance use disorder.Moreover, psychiatric comorbi

Ion irradiation, combined with nanoindentation, has long been recognized as an effective way to study effects of irradiation on the mechanical properties of vip-130al metallic materials.In this research, hardening and creep of ion irradiated Chinese low activation martensitic (CLAM) steel are investigated by nanoindentation.Firstly, it is demonstra

Formaldehyde (FA) is a colorless, flammable, foul-smelling chemical used in building materials and in the production of numerous household chemical goods.Herein, a fluorescent chemosensor for FA is designed and prepared using a selective organ-targeting probe containing naphthalimide as a fluorophore and hydrazine as a FA-binding site.The amine gro
