"It isn't just consultants that need a BSc": student experiences of an Intercalated BSc

More medical schools are moving towards a compulsory intercalated BSc. These courses have not traditionally been aimed at those students interested in general practice and have tended to have limited clinical relevance. This paper explores the perceptions of students who undertook a BSc in primary health care using qualitative methodology comprising semi-structured interviews with students just before completion of their course. Interviews were undertaken with 24 of the 26 students who started the course over a 4-year period. All the students have finished the course and have graduated with good honours degrees. Students refine existing skills and develop new, relevant skills for medicine. The students discussed the prestige (or lack) of a BSc in this field and how the course has impacted on their career decisions. A Primary Health Care BSc such as this appears to give students an in depth and to some, a positive view of general practice and primary care. The course allowed students to develop a more critical approach to medicine and enabled them to develop skills in addition to those acquired from their undergraduate medicine course. They perceived that these skills will serve them throughout their career in whatever branch of medicine they choose

Which way is up? Space and place in virtual learning environments for design

The role of ‘place’ in design education is essential in providing a structured learning experience that can be trusted and which allows dynamic social connections to emerge in the development of reflective practice. With increasing demand for distance and online learning resources, this paper considers how such a sense of place can be arrived at using ‘virtual architecture’. Analogies with physical architectural space – for example ‘homes’, ‘forums’, ‘studios’, ‘libraries’ can be useful, but in many ways the opportunities for design learning in virtual architecture go far beyond what is possible with physical architecture. We describe how the virtual architecture of an Open University course in Design Thinking has consciously tried to create place rather than space, in crafting an environment with intrinsic learning opportunities, and the benefits this has brought to students studying the course

Normal creativity : What 1,038 t‐shirts can tell you about design education

The study of creativity in design has tended to emphasise its value, scarcity, and location in the individual designer rather than in choices made by a consuming public in the context of a wider culture. This paper, in presenting and developing a view of creativity in design as a normal concept, will present initial results from a study of 1038 student design assignments obtained from a distance-learning course in Design Thinking from The Open University in the UK. We show how ‘normal’ distributions of design outputs can be contived from a structured design process and argue that the creativity that is displayed is a natural result of the ‘grammar’ of that process, in a similar way to the syntax of a sentence allowing new combinations of words and meanings to be easily formed. Seen like this creativity is less of an individual ‘gift’, as some theories imply, but a common everyday response to open- ended problems

Impacts of elevated atmospheric ozone on peatland below-ground DOC characteristics

Rising concentrations of tropospheric ozone are having detrimental impacts on the growth of crop and forest species and some studies have reported inhibition of the allocation of carbon below ground. The effects of ozone on peatland ecosystems have received relatively little attention, despite their importance within the global carbon cycle. During this study, cores from a Welsh minerotrophic fen and ombrotrophic bog were exposed to four ambient/ elevated ozone concentration regimes representing current and predicted 2050 profiles. A large and significant reduction in the concentration of porewater dissolved organic carbon (DOC) was recorded in the fen cores exposed to the elevated ozone concentrations (up to −55%), with a concurrent shift to a higher molecularweight of the remaining soil carbon. No effects of ozone on DOC concentrations or characteristics were recorded for the bog cores. The data suggest higher ozone sensitivity of plants growing in the fen-type peatland, that the impacts on the vegetation may affect soil carbon characteristics through a reduction in root exudates and that theremay have been a shift in the source of substrate DOC for microbial consumption from vegetation exudates to native soil carbon. Theremay also have been a direct effect of ozone molecules reacting with soil organic matter after being transported into the soil through the aerenchyma tissue of the overlying vegetation. These qualitative changes in the soil carbon in response to elevated ozone may have important implications for carbon cycling in peatland ecosystems, and therefore climate change

Stable isotope probing: Technical considerations when resolving ¹⁵N-labeled RNA in gradients

RNA based stable isotope probing (SIP) facilitates the detection and identification of active members of microbial populations that are involved in the assimilation of an isotopically labeled compound. ¹⁵N-RNA-SIP is a new method that has been discussed in recent literature but has not yet been tested. Herein, we define the limitations to using ¹⁵N-labeled substrates for SIP and propose modifications to compensate for some of these shortcomings. We have used ¹⁵N-RNA-SIP as a tool for analysing mixed bacterial populations that use nitrogen substrates. After incubating mixed microbial communities with ¹⁵N-ammonium chloride or ¹⁵N₂ we assessed the fractionation resolution of ¹⁵N-RNA by isopycnic centrifugation in caesium trifluoroacetate (CsTFA) gradients. We found that the more isotopic label incorporated, the further the buoyant density (BD) separation between ¹⁵N- and ¹⁴N-RNA, however it was not possible to resolve the labeled from unlabeled RNA definitively through gradient fractionation. Terminal-restriction fragment length polymorphism (T-RFLP) analysis of the extracted RNA and fluorescent in situ hybridisation (FISH) analysis of the enrichment cultures provided some insight into the organisms involved in nitrogen fixation. This approach is not without its limitations and will require further developments to assess its applicability to other nitrogen-fixing environments
