Arguments in a Sartorial Mode, or the Asymmetries of History and Philosophy of Science

History of science and philosophy of science are not perfectly complementary disciplines. Several important asymmetries govern their relationship. These asymmetries, concerning levels of analysis, evidence, theories, writing, and training show that to be a decent philosopher of science is more difficult than being a decent historian. But to be a good historian-well, the degree of difficulty is reversed

Preservation through access: the AHDS performing arts collections in ECLAP and Europeana

This poster provides an overview of the ongoing rescue of valuable digital collections that had been taken down and consequently lost to general access. The University of Glasgow was home to the Arts and Humanities Data Service Performing Arts (AHDS Performing Arts) [1], one of the five arts and humanities data centres that constitute the Arts and Humanities Data Service (AHDS). Since 1996 AHDS supported the creation, curation, preservation and reuse of digital materials for the UK Arts and Humanities research and teaching community. AHDS Performing Arts, based in Glasgow, supported research, learning and teaching in music, dance, theatre, radio, film, television, and performance for thirteen years. Working with the AHDS Executive, relevant performing arts collections have been ingested, documented, preserved, and where possible made available via the AHDS Cross Search Catalogue and Website to researchers, practitioners, and the general public. Furthermore strong relationships were developed with research and teaching community upon a scoping study investigating user needs [2]. In 2007 the co-funders of the AHDS - Arts and Humanities Research Council (AHRC) for the UK and the Joint Information Systems Committee (JISC) - withdrew their funding. A detailed risk assessment report was produced in response to the withdrawal of core funding [3], but to no avail. When the AHDS funding stopped, online access to these cultural resources eventually became discontinued [4]. In 2010, the School of Culture and Creative Arts at the University of Glasgow joined the EU-funded ECLAP project to ensure that at least part of these resources could be accessible for the long term by scholars and practitioners in the performing arts arena, and by the general public. Below we briefly describe the ECLAP project, the AHDS Performing Arts collections progressively available through it and some thoughts on providing preservation through access for this type of digital cultural resources

Laserlight visual cueing device for freezing of gait in Parkinson's disease: a case study of the biomechanics involved

AbstractBackground: Freezing of gait (FOG) is a serious gait disorder affecting up to two-thirds of people with Parkinson's disease (PD). Cueing has been explored as a method of generating motor execution using visual transverse lines on the floor. However, the impact of a laser light visual cue remains unclear. Objective: To determine the biomechanical effect of a laser cane on FOG in a participant with PD compared to a healthy age- and gender-matched control. Methods: The participant with PD and healthy control were given a task of initiating gait from standing. Electromyography (EMG) data were collected from the tibialis anterior (TA) and the medial gastrocnemius (GS) muscles using an 8-channel system. A 10-camera system (Qualisys) recorded movement in 6 degrees of freedom and a calibrated anatomical system technique was used to construct a full body model. Center of mass (COM) and center of pressure (COP) were the main outcome measures. Results: The uncued condition showed that separation of COM and COP took longer and was of smaller magnitude than the cued condition. EMG activity revealed prolonged activation of GS, with little to no TA activity. The cued condition showed earlier COM and COP separation. There was reduced fluctuation in GS, with abnormal, early bursts of TA activity. Step length improved in the cued condition compared to the uncued condition. Conclusion: Laserlight visual cueing improved step length beyond a non-cued condition for this patient indicating improved posture and muscle control

Radar signature determination: Trends and limitations

Modelling studies, as means for assessing what could be called radar signatures, are a part of two radar remote sensing research programs with which the author is affiliated. First, at the University of New South Wales, assessment of SIR-B data is being undertaken for a number of purposes including its value in arid land geomorphological and geological studies, forest and crop assessment, and mapping. A number of early results have been reported, however modelling aspects are still at an early stage. Secondly, the author recently spent 6 months working on SIR-B invertible forest canopy modelling in the Department of Geography at the University of California, Santa Barbara. Results from this work are outlined

IMPLEMENTING AN EXPANDED FOOD AND NUTRITION POLICY: A FARMER'S POINT OF VIEW

The measurement of biaxial strains in coated fabric materials using the disc-replica method

A method of measuring biaxial strains in coated fabric type materials is presented whereby the strain is deduced from the distortion of a circular impression made on the material. The impression is placed on the material when loaded, enabling all measurements to be made with the material in its relaxed, unloaded, state

A Nested Logit Model of Strategic Promotion

Retailers use sales "price promotions" for a number of potential reasons. There is relatively little research, however, on their strategic role among frequently consumed perishable products. Using a two-stage, nested logit model of retail equilibrium, we show that promotion will be most effective (ie. increase store-level sales) if products are highly differentiated, but stores are relatively similar. To test this hypothesis, we an oligopolistic model of promotion rivalry with category-level scanner data from the four largest supermarket retailers in a major U.S. metropolitan market. The results show that promotion has a greater impact on store share than product share, because the elasticity of substitution among stores is larger than the elasticity of substitution among products. Consequently, promotion has its greatest value in driving demand for differentiated products among stores that are similar. This finding supports the observed trend toward premium private label products being offered by supermarket retailers.Research Methods/ Statistical Methods,
