Leveraging the London 2012 Paralympic Games: What legacy for people with disabilities?

The International Paralympic Committee, U.K. Government, and the Organizing Committee for the London 2012 Olympic and Paralympic Games all contended that the London 2012 Paralympic Games would positively impact the lives of disabled people in the United Kingdom, particularly with regard to changing nondisabled attitudes toward disability. All three have claimed partial success during the course of the 4-year period (Olympiad) separating the London and Rio Paralympic Games. However, this is at odds with the findings of Disabled People’s Organizations (DPOs) and the experiences of disabled individuals. This article considers the claims of both sides against a backdrop of public policies that are targeting large-scale benefit cuts, the media coverage of which actually appears to be hardening attitudes toward anyone on benefits and negating any positive impacts from the Games themselves. It argues that the continued predominance of “ableist” perspectives on disability underpins many of the challenges faced by disabled people. The article adopts a historical perspective on the development of legacy-based foundations upon which the disability sport and Paralympic movements originated. It contends that the gradual move toward an elite “Olympic” sports model of competition has actually served to undermine these foundations

Public Diplomacy and the International Paralympic Committee: reconciling the roles of disability advocate and sports regulator

Whilst the link between international diplomacy and the Olympic movement has been the subject of extensive academic and journalistic enquiry, the experience of diplomatic discourse relating to the relatively youthful Paralympic movement has received little attention. It occurs not just in the context of state diplomacy, where for example the Paralympic Games may provide a conduit for the pursuit of specific policy objectives, but also in relation to the engagement of the International Paralympic Committee [IPC] as an evolving non-state actor in the diplomatic process. The idea of the IPC as an advocacy body engaged through public diplomacy in promoting disability rights needs exploration as an element of the contemporary politics of disability. This analysis considers the relationship between the activities of the IPC and wider lobbying by disabled people’s organisations as a means of leveraging change in domestic and international policy toward disability. In relation to the global development agenda, it also assesses IPC responses to the gulf in resourcing for para-sport – as well as related health and education provision - between high- and low-resource regions. It considers the response of the organisation from the perspective of public diplomacy and locates that response within the wider diplomacy of development

Development of Multiple Polymorphic Microsatellite Markers for Ceratina calcarata (Hymenoptera: Apidae) Using Genome-Wide Analysis

The small carpenter bee, Ceratina calcarata (Robertson), is a widespread native pollinator across eastern North America. The behavioral ecology and nesting biology of C. calcarata has been relatively well-studied and the species is emerging as a model organism for both native pollinator and social evolution research. C. calcarata is subsocial: reproductively mature females provide extended maternal care to their brood. As such, studies of C. calcarata may also reveal patterns of relatedness and demography unique to primitively social Hymenoptera. Here, we present 21 microsatellite loci, isolated from the recently completed C. calcarata genome. Screening in 39 individuals across their distribution revealed that no loci were in linkage disequilibrium, nor did any deviate significantly from Hardy-Weinberg following sequential Bonferroni correction. Allele count ranged from 2 to 14, and observed and expected heterozygosities ranged from 0.08 to 0.82 (mean 0.47) and 0.26 to 0.88 (mean 0.56), respectively. These markers will enable studies of population-wide genetic structuring across C. calcarata’s distribution. Such tools will also allow for exploration of between and within-colony relatedness in this subsocial native pollinator

Single-trial multiwavelet coherence in application to neurophysiological time series

A method of single-trial coherence analysis is presented, through the application of continuous muldwavelets. Multiwavelets allow the construction of spectra and bivariate statistics such as coherence within single trials. Spectral estimates are made consistent through optimal time-frequency localization and smoothing. The use of multiwavelets is considered along with an alternative single-trial method prevalent in the literature, with the focus being on statistical, interpretive and computational aspects. The multiwavelet approach is shown to possess many desirable properties, including optimal conditioning, statistical descriptions and computational efficiency. The methods. are then applied to bivariate surrogate and neurophysiological data for calibration and comparative study. Neurophysiological data were recorded intracellularly from two spinal motoneurones innervating the posterior,biceps muscle during fictive locomotion in the decerebrated cat

Subsonic high-angle-of-attack aerodynamic characteristics of a cone and cylinder with triangular cross sections and a cone with a square cross section

Experiments were conducted in the 12-Foot Pressure Wind Tunnel at Ames Research Center on three models with noncircular cross sections: a cone having a square cross section with rounded corners and a cone and cylinder with triangular cross sections and rounded vertices. The cones were tested with both sharp and blunt noses. Surface pressures and force and moment measurements were obtained over an angle of attack range from 30 deg to 90 deg and selected oil-flow experiments were conducted to visualize surface flow patterns. Unit Reynolds numbers ranged from 0.8x1,000,000/m to 13.0x1,000,000/m at a Mach number of 0.25, except for a few low-Reynolds-number runs at a Mach number of 0.17. Pressure data, as well as force data and oil-flow photographs, reveal that the three dimensional flow structure at angles of attack up to 75 deg is very complex and is highly dependent on nose bluntness and Reynolds number. For angles of attack from 75 deg to 90 deg the sectional aerodynamic characteristics are similar to those of a two dimensional cylinder with the same cross section

Warm HCN, C2H2, and CO in the disk of GV Tau

We present the first high-resolution, ground-based observations of HCN and C2H2 toward the T Tauri binary star system GV Tau. We detected strong absorption due to HCN nu_3 and weak C2H2 (nu_3 and nu_2 + (nu_4 + nu_5)^0_+) absorption toward the primary (GV Tau S) but not the infrared companion. We also report CO column densities and rotational temperatures, and present abundances relative to CO of HCN/CO ~0.6% and C2H2/CO ~1.2% and an upper limit for CH4/CO < 0.37% toward GV Tau S. Neither HCN nor C2H2 were detected toward the infrared companion and results suggest that abundances may differ between the two sources.Comment: 23 pages, 6 figures, accepted by Ap
