The aims of this mixed methods study were to gain insight into how individual assessors determine an Objective Structured Clinical Assessment (OSCA) result for undergraduate nursing students and identify whether individual assessor perceptions and professional characteristics have an impact on students' results. Results from 25 participants showed that although less than half (44%) of the participants were teaching in the course that they were assessing, the participants were highly experienced clinicians and nearly three-quarters (72%) had completed formal teaching qualifications. There were wide variations in pass rates (16.7-90%) between assessors. The widest disparity was observed between assessors with and those …

The study of uranium-series (U-series) isotopes in soil and sediment materials has been proposed to quantify rates and timescales of soil production and sediment transport. Previous works have studied bulk soil or sediment material, which is a complex assemblage of primary and secondary minerals and organic compounds. However, the approach relies on the fractionation between U-series isotopes in primary minerals since they were liberated from the parent rock via weathering. In addition, secondary minerals and organic compounds have their own isotopic compositions such that the composition of the bulk material may not reflect that of primary minerals. Hence, there is …
