Dissecting action sports studies: Past, present, and beyond

The term “action sports” broadly refers to a wide range of mostly individualized activities such as BMX, kite-surfing, skateboarding, surfing, and snowboarding that differed – at least in their early phases of development – from traditional rule-bound, competitive, regulated Western “achievement” sport cultures ( Booth and Thorpe, 2007 ; Kusz, 2007a ; Wheaton 2004, 2010 ). Various categorizations have been used to describe these activities, including extreme, lifestyle, and alternative sports. In this chapter, however, the term action sports is used as it is currently the preferred term among committed participants and industry members in North America and Australasia (many of whom reject the overly commercialized “extreme” moniker imposed upon them by transnational media and mainstream sponsors during the mid- and late 1990s). Many action sports gained popularity during the new leisure trends of the 1960s and 1970s and increasingly attracted alternative youth, who appropriated these activities and infused them with a set of hedonistic and carefree philosophies and subcultural styles ( Booth and Thorpe, 2007 ; Thorpe and Wheaton, 2011a ; Wheaton, 2010 )

Effective Action Studies of Quantum Hall Spin Textures

We report on analytic and numerical studies of spin textures in quantum Hall systems using a long-wavelength effective action for the magnetic degrees of freedom derived previously. The majority of our results concern skyrmions or solitons of this action. We have constructed approximate analytic solutions for skyrmions of arbitrary topological and electric charge and derived expressions for their energies and charge and spin radii. We describe a combined shooting/relaxational technique for numerical determination of the skyrmion profiles and present results that compare favorably with the analytic treatment as well as with Hartree-Fock studies of these objects. In addition, we describe a treatment of textures at the edges of quantum Hall systems within this approach and provide details not reported previously.Comment: 13 pages, 10 figure

Themes, iteration and recoverability in action research

This paper develops three concepts important to the practice of action research recoverability, research themes, and iteration by highlighting their applicability beyond single action research studies. The concepts are discussed against a program of action research, undertaken by a multidisciplinary research team, with a research focus on local, sector and national evels. This contrasts with the more usual pattern of action research in single situations. Action research is criticized on the grounds that it lacks generalizability and external validity from one-off studies. Goodness criteria have been derived to address these and other criticisms. The recoverability criterion, less strong than the repeatability of experimentation, is central to these. A second concept, that of research themes, links the recoverability criterion and iteration in action research. Iteration within and between projects and the notion of critical mass, of doing work in more than one setting, address the limitations of single setting studies

Empirical studies of financial innovation: lots of talk, little action?

This paper reviews the extant empirical studies of financial innovation. Adopting broad criteria, the authors found just two dozen studies, over half of which (fourteen) had been conducted since 2000. Since some financial innovations are examined by more than one study, only fourteen distinct phenomena have been covered. Especially striking is the fact that only two studies are directed at the hypotheses advanced in many broad descriptive articles concerning the environmental conditions (e.g., regulation, taxes, unstable macroeconomic conditions, and ripe technologies) spurring financial innovation. The authors offer some tentative conjectures as to why empirical studies of financial innovation are comparatively rare. Among their suggested culprits is an absence of accessible data. The authors urge financial regulators to undertake more surveys of financial innovation and to make the survey data more available to researchers.Financial modernization ; Banks and banking ; Patents ; Securities

Extending boundaries: young people as action researchers

Action research is generally undertaken by adults as a process of systematic action planning and enquiry which can lead to improvements in aspects of their professional practices. This article challenges and extends conventional understanding of action research to show how young people, between the ages of 10 and 17, can interrogate and improve their own practices – both individually and collectively. Brief accounts of four case studies – three British and one South African – are presented, along the lines of a patchwork narrative. Each ‘patch’ in turn contributes to the later collation of a theme and ideas that ‘stitch’ the studies together

Natural disasters and the issue of responsibility for the victim states

Dr C. Chatterjee considers whether natural disasters are an entirely national phenomenon, or if their effects can be minimised by concerted international action.

Three-algebra for supermembrane and two-algebra for superstring

While string or Yang-Mills theories are based on Lie algebra or two-algebra structure, recent studies indicate that M-theory may require a one higher, three-algebra structure. Here we construct a covariant action for a supermembrane in eleven dimensions, which is invariant under global supersymmetry, local fermionic symmetry and worldvolume diffeomorphism. Our action is classically on-shell equivalent to the celebrated Bergshoeff-Sezgin-Townsend action. However, the novelty is that we spell the action genuinely in terms of Nambu three-brackets: All the derivatives appear through Nambu brackets and hence it manifests the three-algebra structure. Further the double dimensional reduction of our action gives straightforwardly to a type IIA string action featuring two-algebra. Applying the same method, we also construct a covariant action for type IIB superstring, leading directly to the IKKT matrix model.Comment: 1+15 pages, no figure; Refs added, Accepted for publication in JHE

Interdisciplinary communication for environmental effectiveness: Forward-looking lessons from leadership, followership and strategic entrepreneurship

This article contends that interdisciplinary interactions, and temporal factors, influence communications between environment and organisations in ways that are understudied. It tracks the evolution of one recent interface between strategy and entrepreneurship to illustrate the process in action and to suggest how that hybrid can, in turn, interface with new leadership research to improve organisational responses at a time of fast-moving change. In addition, it makes a case for integrating action learning, action research, and action inquiry, as a method for generating more relevant and forward-looking case material than retrospective studies of past practice
