Characterisation of tissue-type metabolic content in secondary progressive multiple sclerosis: a magnetic resonance spectroscopic imaging study
Proton magnetic resonance spectroscopy yields metabolic information and has proved to be a useful addition to structural imaging in neurological diseases. We applied short-echo time Spectroscopic Imaging in a cohort of 42 patients with secondary progressive multiple sclerosis (SPMS). Linear modelling with respect to brain tissue type yielded metabolite levels that were significantly different in white matter lesions compared with normal-appearing white matter, suggestive of higher myelin turnover (higher choline), higher metabolic rate (higher creatine) and increased glial activity (higher myo-inositol) within the lesions. These findings suggest that the lesions have ongoing cellular activity that is not consistent with the usual assumption of ‘chronic’ lesions in SPMS, and may represent a target for repair therapies
Three arguments against ‘soft innovation’: towards a richer understanding of cultural innovation
This paper critiques recent research on innovation in the cultural and creative industries. In particular, this paper examines Paul Stoneman’s idea of ‘soft innovation’ as a jumping off point for discussing theories of cultural innovation more broadly. Three critiques are advanced. Firstly, soft innovation is a theoretical perspective that has developed from neoclassical economics, and is therefore vulnerable to criticisms levelled at neoclassical explanations of economic behaviour. Secondly, the theory of soft innovation can be criticised for being contin- gently inaccurate: the observed reality of cultural industries and marketplaces may not reflect the theory’s premises. Thirdly, because soft innovation defines the significance of an innovation in terms of marketplace success, it implies that only high-selling cultural products are significant, a difficult claim to substantiate. This paper concludes by arguing that our understanding of innovation in the cultural sphere can benefit from a multi-disciplinary approach grounded in the full gamut of human creativity
