What guides student learning in the clinical years: A mixed methods study exploring study behaviours prior to the UK Medical Licensing Assessment (UKMLA).

PURPOSE: Student study behaviours that prioritise the UKMLA content map over the local curriculum are a significant risk for UK medical education. To mitigate this, we describe a student-centred faculty process to improve local curriculum guidance based on an evaluation of student study behaviours, concerns and needs. Responses informed the build of an online curriculum map. METHODS: A mixed methods approach was adopted, including an online anonymous survey exploring student study behaviours and preferences for curricular guidance. This was followed by student-led focus groups to explore emergent themes further. Qualitative data underwent reflexive thematic analysis. RESULTS: 121 students responded to the survey, of which 12 consented to participate in two student-led focus groups. Five key themes emerged, including motivation for learning, student use of the intended curriculum, student experience of the enacted curriculum, the hidden curriculum, and expectations of an online curriculum map. CONCLUSIONS: A participatory framework enabled shared aims and responsive outcomes for curricular development in the run up to the UKMLA. Student responses led to clarification of guidance, reorganisation of learning resources and optimal design of an online curriculum map which linked all content in a visible, UKMLA aligned framework, accessible to all students and teachers

Sustainable agriculture and the production of biomass for energy use

Modern bioenergy is seen as a promising option to curb greenhouse gas emissions. There is, however, a potential competition for land and water between bioenergy and food crops. Another question is whether biomass for energy use can be produced in a sustainable manner given the current conventional agricultural production practices. Other than the land and water competition, this question is often neglected in scenarios to meet a significant part of global energy demand with bioenergy. In the following, I address this question. There are sustainable alternatives, for example organic agriculture, to avoid the negative environmental effects of conventional agriculture. Yet, meeting a significant part of global energy demand with biomass grown sustainably may not be possible, as burning significant quantities of organic matter - inherent in bioenergy use - is likely to be incompatible with the principles of such alternatives, which often rely on biomass input for nutrient balance. There may therefore be a trade-off between policies and practices to increase bioenergy and those to increase sustainability in agriculture via practices such as organic farming. This is not a general critique of bioenergy but it points to additional potential dangers of modern bioenergy as a strategy to meet significant parts of world energy demand

Most species are not limited by an Amazonian river postulated to be a border between endemism areas

Abstract At broad scales in the Amazon, it is often hypothesized that species distributions are limited by geographical barriers, such as large rivers (river-barrier hypothesis). This hypothesis has been used to explain the spatial-distribution limits of species and to indicate endemism areas for several phylogenetic lineages. We tested the ability of the river-barrier hypothesis to explain patterns of species diversity and spatial-distribution limits for 1952 easily-detected species in 14 taxonomic groups that occur around the Madeira River, and our results indicate that the hypothesis that the Madeira River is the border between endemism areas and explains much of the diversity found in the region is inappropriate for >99% of species. This indicates that alternative hypotheses should be proposed to explain the limits of distributions of species around the Madeira River, as well as a revision of the criteria that are used to determine species-endemism areas
