Enfoques historiográficos y representaciones sociales en los libros de texto. Un estudiocomparativo, España - Francia - Inglaterra = Historiographical approaches and social representations in textbooks. A comparative study, Spain - France - England

This paper analyzes the historiographical approaches and national, European and extra-European social representations on textbooks of Secondary Education in Spain, France and England. We have chosen for the sample 18 textbooks of the first two years of secondary education in the three countries. We have selected three publishers of big presence in classrooms in each of the territories (Anaya, Oxford and VicensVives for Spain; Belin, Bordas and Lelivrescolaire for France, and Collins, Heinemann and Hodder Education for England). The results show different historiographical approaches in textbooks analyzed, with a greater weight of structuralism and positivism in the Spanish case; a clear influence of the latest generations of Annales in the French case; and an important weight of social history and history from below in the English case. Also the three countries differ in social representations. French and Spanish textbooks raise the historical account within a European framework of which they feel participants. However the English textbooks present the construction of the English nation (especially in the centuries of the Middle Ages and Modern Age) from a very Anglocentric perspective

International instructional systems: social studies

This paper reports on research conducted as part of the International Instructional System Study that explored five subject areas across nine jurisdictions in six high-performing countries. The Study’s overall aim was to understand what, if anything, there is in common in the curricula and assessment arrangements among the high-performing jurisdictions to see if there are aspects of instructional system design that might account, in part, for high performance. This paper focuses on social studies which in most jurisdictions includes elements of history, geography and citizenship and highlights a number of emerging issues. These include the advantages and disadvantages of teaching history and geography separately or within a social studies programme; the extent to which key concepts are embedded within the social studies/history/geography curricula; whether the level of demand should be considered in terms of a generic taxonomy or in terms of subject specific models; how progression might be defined and considerations of an appropriate balance between teacher assessment and external assessment

Understanding what young people know: methodological and theoretical challenges in researching young people’s knowledge and understanding of the Holocaust

This article draws on research into young people’s knowledge and understanding of the Holocaust conducted by the UCL Centre for Holocaust Education (CfHE). Two questions are addressed: “How can we theorize and measure development and progression in young people’s historical knowledge and understanding of the Holocaust?” and “How can empirical social scientific research methods be used to help us describe young people’s knowledge and understanding of the Holocaust?” This article reviews methodologies developed by the CfHE and exemplifies a research tool and two complementary approaches to analysis, focused on young people’s descriptions of the Holocaust

Challenges of Incorporating Digital Health Technology Outcomes in a Clinical Trial: Experiences from PD STAT.

Digital health technologies (DHTs) have great potential for use as clinical trial outcomes; however, practical issues need to be addressed in order to maximise their benefit. We describe our experience of incorporating two DHTs as secondary/exploratory outcome measures in PD STAT, a randomised clinical trial of simvastatin in people with Parkinson's disease. We found much higher rates of missing data in the DHTs than the traditional outcome measures, in particular due to technical and software difficulties. We discuss methods to address these obstacles in terms of protocol design, workforce training and data management

What is School History For? British Student-teachers' Perspectives // ¿Para Qué Sirve La Enseñanza De La Historia? Perspectivas De Docentes y Estudiantes Británicos

Relatively little is known about student-teachers’ ideas about the nature and purpose of history education. This paper reviews research on this issue and presents an analysis of how the aims of school history have been conceptualised within successive versions of the English National Curriculum since 1991. Data arising from online discussion among 40 student-teachers of history in England are subjected to qualitative analysis, revealing the wide range of views that they held about the aims and purposes of school history. Contrasts and continuities are identified between the student-teachers’ thinking and the thinking of English policy makers and opinion formers, leading to the conclusion that curriculum developers need to pay much closer attention than they have in the past to the thinking of the current and future history teachers who are ultimately responsible for the implementation of the curriculum. // Se sabe relativamente poco acerca de las ideas de los maestros en formación sobre la naturaleza y el propósito de la enseñanza de la historia. Este artículo revisa la investigación sobre este tema y presenta un análisis de cómo el currículum nacional inglés ha conceptualizado los objetivos de la enseñanza de la historia desde el año 1991. Los datos derivados de una discusión en línea permiten explorar el pensamiento de 40 docentes de historia en prácticas y analizarlos cualitativamente para conocer la variedad de ideas presentes en esta muestra. Los estudiantes tuvieron una amplia gama de puntos de vista sobre los objetivos y propósitos de la enseñanza de la historia y se identificaron las divergencias y convergencias entre el pensamiento de los estudiantes y el pensamiento de los políticos ingleses y de los líderes de opinión. Se concluye que quienes desarrollan los currículos deben prestar mucha más atención que en el pasado al pensamiento de los actuales y futuros profesores de historia, que son en último término los responsables del diseño de las propuestas curriculares

A novel cell culture model for studying differentiation and apoptosis in the mouse mammary gland.

BACKGROUND: This paper describes the derivation and characterization of a novel, conditionally immortal mammary epithelial cell line named KIM-2. These cells were derived from mid-pregnant mammary glands of a mouse harbouring one to two copies of a transgene comprised of the ovine beta-lactoglobulin milk protein gene promoter, driving expression of a temperature-sensitive variant of simian virus-40 (SV40) large T antigen (T-Ag). RESULTS: KIM-2 cells have a characteristic luminal epithelial cell morphology and a stable, nontransformed phenotype at the semipermissive temperature of 37 degrees C. In contrast, at the permissive temperature of 33 degrees C the cells have an elongated spindle-like morphology and become transformed after prolonged culture. Differentiation of KIM-2 cells at 37 degrees C, in response to lactogenic hormones, results in the formation of polarized dome-like structures with tight junctions. This is accompanied by expression of the milk protein genes that encode beta-casein and whey acidic protein (WAP), and activation of the prolactin signalling molecule, signal transducer and activator of transcription (STAT)5. Fully differentiated KIM-2 cultures at 37 degrees C become dependent on lactogenic hormones for survival and undergo extensive apoptosis upon hormone withdrawal, as indicated by nuclear morphology and flow cytometric analysis. KIM-2 cells can be genetically modified by stable transfection and clonal lines isolated that retain the characteristics of untransfected cells. CONCLUSION: KIM-2 cells are a valuable addition, therefore, to currently available lines of mammary epithelial cells. Their capacity for extensive differentiation in the absence of exogenously added basement membrane, and ability to undergo apoptosis in response to physiological signals will provide an invaluable model system for the study of signal transduction pathways and transcriptional regulatory mechanisms that control differentiation and involution in the mammary gland

Changes in microphytobenthos fluorescence over a tidal cycle: implications for sampling designs

Intertidal microphytobenthos (MPB) are important primary producers and provide food for herbivores in soft sediments and on rocky shores. Methods of measuring MPB biomass that do not depend on the time of collection relative to the time of day or tidal conditions are important in any studies that need to compare temporal or spatial variation, effects of abiotic factors or activity of grazers. Pulse amplitude modulated (PAM) fluorometry is often used to estimate biomass of MPB because it is a rapid, non-destructive method, but it is not known how measures of fluorescence are altered by changing conditions during a period of low tide. We investigated this experimentally using in situ changes in minimal fluorescence (F) on a rocky shore and on an estuarine mudflat around Sydney (Australia), during low tides. On rocky shores, the time when samples are taken during low tide had little direct influence on measures of fluorescence as long as the substratum is dry. Wetness from wave-splash, seepage from rock pools, run-off, rainfall, etc., had large consequences for any comparisons. On soft sediments, fluorescence was decreased if the sediment dried out, as happens during low-spring tides on particularly hot and dry days. Surface water affected the response of PAM and therefore measurements used to estimate MPB, emphasising the need for care to ensure that representative sampling is done during low tide

Evidence for a pervasive 'idling-mode' activity template in flying and pedestrian insects

This is the final version. Available on open access from the Royal Society via the DOI in this recordUnderstanding the complex movement patterns of animals in natural environments is a key objective of 'movement ecology'. Complexity results from behavioural responses to external stimuli but can also arise spontaneously in their absence. Drawing on theoretical arguments about decision-making circuitry, we predict that the spontaneous patterns will be scale-free and universal, being independent of taxon and mode of locomotion. To test this hypothesis, we examined the activity patterns of the European honeybee, and multiple species of noctuid moth, tethered to flight mills and exposed to minimal external cues. We also reanalysed pre-existing data for Drosophila flies walking in featureless environments. Across these species, we found evidence of common scale-invariant properties in their movement patterns; pause and movement durations were typically power law distributed over a range of scales and characterized by exponents close to 3/2. Our analyses are suggestive of the presence of a pervasive scale-invariant template for locomotion which, when acted on by environmental cues, produces the movements with characteristic scales observed in nature. Our results indicate that scale-finite complexity as embodied, for instance, in correlated random walk models, may be the result of environmental cues overriding innate behaviour, and that scale-free movements may be intrinsic and not limited to 'blind' foragers as previously thought.Rothamsted research receives grant aided support from the Biotechnology and Biological Sciences Research Council.
