Studies with computer-experienced children in the UK and less experienced in Ukraine explored the potential for VEs in teaching historical chronology to middle-school children aged 10–12 years old. Active fly-through VEs had been previously used successfully with primary school children aged 8–9 years old (given specific training with the environment) when they were subsequently tested for their ability to order events chronologically. All VEs in the present studies included a training element and active challenge, both found previously to enhance learning in other age groups. Ukraine children were trained and tested. UK children here were trained and tested, then retrained and retested to examine savings. Unlike other age groups, no significant benefit was seen for VE training compared with PowerPoint and Text conditions in either study. Possible explanations for the ineffectiveness of VE training for children of middle school age will be discussed. Keywords: timeline, chronographics

The paper is concerned with the role of art and design in the history and philosophy of computing. It offers insights arising from research into a period in the 1960s and 70s, particularly in the UK, when computing became more available to artists and designers, focusing on John Lansdown (1929-1999) and Bruce Archer (1922-2005) in London. Models of computing interacted with conceptualisations of art, design and related creative activities in important ways.

The carbonate chemistry of seawater fromthe Ria Formosa lagoon was experimentallymanipulated, by diffusing pure CO2, to attain two reduced pH levels, by−0.3 and−0.6 pH units, relative to unmanipulated seawater. After 84 days of exposure, no differences were detected in terms of growth (somatic or shell) or mortality of juvenile mussels Mytilus galloprovincialis. The naturally elevated total alkalinity of the seawater (≈3550 μmol kg−1) prevented under-saturation of CaCO3, evenunder pCO2 values exceeding 4000 μatm, attenuating the detrimental effects on the carbonate supply-side. Even so, variations in shell weight showed that net calcification was reduced under elevated CO2 and reduced pH, although the magnitude and significance of this effect varied among size-classes. Most of the loss of shell material probably occurred as post-deposition dissolution in the internal aragonitic nacre layer. Our results show that, even when reared under extreme levels of CO2- induced acidification, juvenileM. galloprovincialis can continue to calcify and grow in this coastal lagoon environment. The complex responses of bivalves to ocean acidification suggest a large degree of interspecific and intraspecific variability in their sensitivity to this type of perturbation. Further research is needed to assess the generality of these patterns and to disentangle the relative contributions of acclimation to local variations in seawater chemistry and genetic adaptation.

As academic disciplines, Physical Education and Sport History share interests in performance, participation, physique and the politics of corporeal praxis. Engendering unity between the two disciplines, however, has not been without concern. Scholars working within (and across) both fields have highlighted how the potential for shared knowledge production and meaning making has been, to a degree, stymied by epistemological and methodological criticism and trepidation. Issues over contextualization, rigour, narrative schemas, conceptualizations of the body, and notions of agency and power still, in particular, constrain our current educational and historical readings and renderings of physical culture(s). Scholarly schisms and methodological differences can be overcome, however, and need not prohibit disciplinary collaborations that might better address prevailing ethical questions and affect political cause; vis-à-vis the body, the physical and sport. This brief piece is, consequently, recourse to the scholarly symbiosis between Physical Education and Sport History and echoes the encouragement of our earlier colleagues to play, inquire, create and produce together.

This article proposes a critical analysis of recent interpretations made to the history of architecture and urban planning in the Portuguese colonial context in the twentieth century, particularly in the former African territories. More generally, it intends to explore how the internal history produced by specific fields of activity, such as architecture or urbanism, can reinforce the logic of a national and nationalized history. This effect is due partly to the fact that the legitimacy of these fields is largely dependent on the national identification in the context of activities that are internationalized. I will argue that the specific field of activity, while creating this internal discourse, can directly or indirectly produce representations of the nation, its history and its people on a larger scale, penetrating popular culture and influencing a shared common sense. In the case in question, the internal discourse on architectural and urbanistic works, on authors and styles, eventually reinforces an idealized and idyllic image of Portuguese colonialism.
