The changing role of pre-admission work experience (clinical visits) in Therapeutic Radiography, Diagnostic Radiography and Operating Department Practice: Student perspectives (Part 1).

Introduction: Clinical visits (work experience opportunities) are a recommended part of admissions processes for many diagnostic and therapeutic radiography courses but not for operating department practice (ODP) where observational visits are challenging for applicants to obtain. The Covid-19 pandemic interrupted access to visits for all prospective students; this study presents a review of the value of clinical visits and alternatives.

Methods: This article reports the initial qualitative phase of a three-phase mixed methods study.

The changing role of pre-admission work experience (clinical visits) in therapeutic radiography, diagnostic radiography and operating department practice: Academic perspectives (part 2).

Introduction: A clinical visit (work experience) provides an opportunity for prospective students, prior to registration, to visit a clinical department to observe health professionals in practice. The Covid-19 pandemic interrupted access to clinical visits; this article explores the value of clinical visits and the alternatives implemented as a response to Covid-19 restrictions from an academic perspective.

Methods: This article reports the quantitative phase of a three-phase mixed methods study.

Megafaunal isotopes reveal role of increased moisture on rangeland during late Pleistocene extinctions.

The role of environmental change in the late Pleistocene megafaunal extinctions remains a key question, owing in part to uncertainty about landscape changes at continental scales. We investigated the influence of environmental changes on megaherbivores using bone collagen nitrogen isotopes (n = 684, 63 new) as a proxy for moisture levels in the rangelands that sustained late Pleistocene grazers. An increase in landscape moisture in Europe, Siberia and the Americas during the Last Glacial-Interglacial Transition (LGIT; ~25-10 kyr bp) directly affected megaherbivore ecology on four continents, and was associated with a key period of population decline and extinction.

Taxonomic review of the late Cenozoic megapodes (Galliformes: Megapodiidae) of Australia.

Megapodes are unusual galliform birds that use passive heat sources to incubate their eggs. Evolutionary relationships of extant megapode taxa have become clearer with the advent of molecular analyses, but the systematics of large, extinct forms (, ) from the late Cenozoic of Australia has been a source of confusion. It was recently suggested that the two species of were synonymous, and that this taxon dwarfed into the extant malleefowl in the Late Pleistocene.
