In what Williams (1975) described as a dramatised world, a great deal of children’s historical knowledge is acquired through dramatised versions of historical events. As the characters who actually took part in historical events become the dramatis personae of re-enacted accounts, their stories are edited not only to meet dramatic necessities but the social, psychological and cultural needs of both storytellers and audience. The process of popularising history in this way thus becomes as much about the effects of events on people as the events themselves, so mirroring debates within history education regarding the teaching of ‘facts’ and the development of empathy. In this article, Andy Kempe explores how stories of evacuees and other ‘war children’ have been dramatised in traditional playscripts and through structured ‘process dramas’ in schools in the British Isles. It argues that drama and history as curriculum subjects may find common ground, and indeed complement each other, in the development of a critical literacy concerned not so much with either fact or empathy as with interrogating both why and how stories are told.

Background: Deficits in reading airment (SLI), Down syndrome (DS) and autism spectrum disorders (ASD). Methods: In this review (based on a search of the ISI Web of Knowledge database to 2011), the Simple View of Reading is used as a framework for considering reading comprehension in these groups. Conclusions: There is substantial evidence for reading comprehension impairments in SLI and growing evidence that weaknesses in this domain are common in DS and ASD. Further, in these groups reading comprehension is typically more impaired than word recognition. However, there is also evidence that some children and adolescents with DS, ASD and a history of SLI develop reading comprehension and word recognition skills at or above the age appropriate level. This review of the literature indicates that factors including word recognition, oral language, nonverbal ability and working memory may explain reading comprehension difficulties in SLI, DS and ASD. In addition, it highlights methodological issues, implications of poor reading comprehension and fruitful areas for future research.

Sustainable lake management for nutrient-enriched lakes must be underpinned by an understanding of both the functioning of the lake, and the origins of changes in nutrient loading from the catchment. To date, limnologists have tended to focus on studying the impact of nutrient enrichment on the lake biota, and the dynamics of nutrient cycling between the water column, biota and sediments within the lake. Relatively less attention has been paid to understanding the specific origins of nutrient loading from the catchment and nutrient transport pathways linking the lake to its catchment. As such, when devising catchment management strategies to reduce nutrient loading on enriched lakes, assumptions have been made regarding the relative significance of non-point versus point sources in the catchment. These are not always supported by research conducted on catchment nutrient dynamics in other fields of freshwater science. Studies on nutrient enrichment in lakes need to take account of the history of catchment use and management specific to each lake in order to devise targeted and sustainable management strategies to reduce nutrient loading to enriched lakes. Here a modelling approach which allows quantification of the relative contribution of nutrients from each specific point and non-point catchment source over the course of catchment history is presented. The approach has been applied to three contrasting catchments in the U.K. for the period 1931 to present. These are the catchment of Slapton Ley in south Devon, the River Esk in Cumbria and the Deben Estuary in Suffolk. Each catchment showed marked variations in the nature and intensity of land use and management. The model output quantifies the relative importance of point source versus non-point livestock and land use sources in each of the catchments, and demonstrates the necessity for an understanding of site-specific catchment history in devising suitable management strategies for the reduction of nutrient loading on enriched lakes.

Based on a three year action research project, this study examines one strand of that research, namely the impact that ‘purpose’, i.e. exploring the range of rationales for studying a subject, has in helping white trainee teachers embrace cultural and ethnic diversity within their teaching. Through ‘purpose’ trainees explored different reasons why history should be taught (and by implication what content should be taught and how it should be taught) and the relationship of these reasons to diversity. Focusing on ‘purpose’ appears to have a positive impact on many trainees from white, mono-ethnic backgrounds, enabling them to bring diversity into the school curriculum, in this case history teaching. It offers one way to counter concerns about issues of ‘whiteness’ in the teaching profession and by teaching a more relevant curriculum has a potential positive impact on the achievement of students from minority ethnic backgrounds.

Hippurate, the glycine conjugate of benzoic acid, is a normal constituent of the endogenous urinary metabolite profile and has long been associated with the microbial degradation of certain dietary components, hepatic function and toluene exposure, and is also commonly used as a measure of renal clearance. Here we discuss the potential relevance of hippurate excretion with regards to normal endogenous metabolism and trends in excretion relating to gender, age, and the intestinal microbiota. Additionally, the significance of hippurate excretion with regards to disease states including obesity, diabetes, gastrointestinal diseases, impaired renal function, psychological disorders and autism, as well as toxicity and parasitic infection, are considered.

All of our knowledge of history is mediated in one way or another. Even the experience of first hand witnesses are, it may be argued, subject to semiotic influences such as physical and emotional position, attitudinal point of view and accuracy of recall. A great deal of historical knowledge is acquired through dramatised versions of historical events. As the characters who actually took part in historical events become the dramatis personae of re-enacted accounts, their stories are edited not only to meet dramatic necessities but the social, psychological and cultural needs of both storytellers and audience. The process of popularising history in this way thus becomes as much about the effects of events on people as the events themselves. This chapter describes and analyses the way in which four historical events have formed the basis of school based drama workshops that explore this process. The Player in Tom Stoppard’s ‘Rosencrantz and Guildenstern Are Dead’ posits that actors do on stage what others are supposed to do off, which, he claims, ‘is a kind of integrity.’ The chapter discusses how drama may be used to explore not only stories from history but how those stories may be mediated and so become open to multiple interpretations. The process of dramatising events from history provides opportunities to develop and exercise a critical literacy that is concerned not so much with either fact or empathy as with interrogating both why and how stories are told. Thus, the experience of exploring the symbiotic relationship between drama and history is dependent on an internal logic which may indeed be perceived as a kind of integrity.

Version 1 of the Global Charcoal Database is now available for regional fire history reconstructions, data exploration, hypothesis testing, and evaluation of coupled climate–vegetation–fire model simulations. The charcoal database contains over 400 radiocarbon-dated records that document changes in charcoal abundance during the Late Quaternary. The aim of this public database is to stimulate cross-disciplinary research in fire sciences targeted at an increased understanding of the controls and impacts of natural and anthropogenic fire regimes on centennial-to-orbital timescales. We describe here the data standardization techniques for comparing multiple types of sedimentary charcoal records. Version 1 of the Global Charcoal Database has been used to characterize global and regional patterns in fire activity since the last glacial maximum. Recent studies using the charcoal database have explored the relation between climate and fire during periods of rapid climate change, including evidence of fire activity during the Younger Dryas Chronozone, and during the past two millennia.
