C^\infty smoothing for weak solutions of the inhomogeneous Landau equation

We consider the spatially inhomogeneous Landau equation with initial data that is bounded by a Gaussian in the velocity variable. In the case of moderately soft potentials, we show that weak solutions immediately become smooth and remain smooth as long as the mass, energy, and entropy densities remain under control. For very soft potentials, we obtain the same conclusion with the additional assumption that a sufficiently high moment of the solution in the velocity variable remains bounded. Our proof relies on the iteration of local Schauder-type estimates.Comment: 23 pages, updated with to-be-published versio

'From grade B thrillers to deluxe chillers': prestige horror, female audiences, and allegories of spectatorship in The Spiral Staircase (1946)

This paper examines the prestige ‘shocker’ The Spiral Staircase (1946), suggesting that it challenges the perception of the decline in quality in the horror genre in the 1940s, as well as assumptions in scholarship that the genre has historically been addressed to a male audience. Whilst the film is usually discussed as a woman’s film, on release it was centred as part of a distinct shift in the horror genre from ‘grade B thrillers to deluxe chillers’. The reclassification of films like The Spiral Staircase as woman’s films could be seen as an attempt to make text fit established theory – the film is addressed to a female audience and thus cannot be a horror film. Through an analysis of textual and extra-textual discourses, including reception and publicity materials, this paper will challenge the pervasive theories that suggest female pleasure or identification is unattainable in horror spectatorship. Whilst the theory is that women refuse to look at horror, averting their eyes or turning away, in 1946 The Spiral Staircase asked a predominantly female audience to take a closer look and question the very act of looking at the cinema screen

Resisting relocation and reconceptualising authenticity: the experiential and emotional values of the Southbank Undercroft London UK

The tagline, ‘You Can’t Move History: You Can Secure the Future’, encapsulated the battle at the heart of the campaign to retain the Southbank Undercroft skate spot in the light of planned redevelopment of the Southbank Centre, London. The 2013-15 campaign against relocation adopted a position of no compromise and provides a lens through which three key areas of heritage theory and practice can be examined. Firstly, the campaign uses the term found space to reconceptualise authenticity and places a greater emphasis on embodied experiences of, and emotional attachments to, historic urban spaces. Secondly, the paper argues that the concept of found space opens up a discussion surrounding the role of citizen expertise in understanding the experiential and emotional values of historic urban spaces. Finally, the paper considers the wider relevance of found space in terms of reconceptualising authenticity in theory and practice. The paper is accompanied by the award-winning film ‘You Can’t Move History’ which was produced by the research team in collaboration with Paul Richards from Brazen Bunch and directed by skater, turned filmmaker, Winstan Whitter

Virtual Design Based Research

Instructional materials for the online course may be designed with rich multimedia content and innovative approaches. Student engagement with these materials is unseen and left to be inferred. Design based research is an approach used to study intervention in the context of an authentic classroom. It can be applied to the online course to study the impact of instructional design decisions and the effectiveness of multimedia integration. The technology used to support the online course can be used to collect usage data and participant evaluations

Designing Dynamic Online Lessons with Multimedia Representations

The focus of this paper is on the use of multimedia representations in the online lesson. The information presented here may be of interest to online instructors with varied levels of experience, yet it is geared more toward those who are new to online teaching. A central feature of this paper is the importance of the lesson plan, which can include identification of how multimedia will be used to create instructional messages for the lesson. The potential exists to increase the quality of instruction through the careful use of static and dynamic multimedia representations. Support for the use of multiple representations is documented in the research literature
