Medical Technology's Source of Innovation

This article presents research based on a case study of Bern University Hospital and the Greater Bern Area that analyses the hospital's influence on innovation in the regional medical device industry. The study draws upon the concept of sectoral innovation systems enlarged with a space-oriented model of agents' innovation-related behaviour. Its main data stem from semi-structured interviews with representatives from regional companies and the hospital. The findings confirm the systemic character of innovation in medical technology and the role of university hospitals as the main functional source of medical device innovation. At the inception of the medical device industry, innovations were implemented in a regional setting, but with the maturation of the industry, this setting has yielded to an almost global setting for innovation. This international setting became prevalent largely due to the marketing considerations of the industry, showing that from an industrial management point of view, product innovation and the diffusion of innovation are heavily interlinked activities. The article concludes that the hospital's relevant influence at a regional level lies not in the present but in the past, when timely innovative impulses from physicians enabled this regional industry's successful participation in the emerging medical device sector.     

Pricing the revolution: Financial analysts respond to the Egyptian uprising (Respond to this article at http://www.therai.org.uk/at/debate)

On 25 January 2011, thousands of Egyptians gathered to raise their voices against their country's long‐standing president, Hosni Mubarak. I received the news as I was conducting fieldwork in a research department of an international bank based in Zurich. Here, I document how Egypt's revolution was perceived, discussed and interpreted within this research department. I argue that the process of ‘pricing the revolution’ that took place may be understood as an ongoing interaction among participants in financial markets and that, given this, it should be understood as a social process, rather than an economic one.     

A geometric morphometric relationship predicts stone flake shape and size variability

The archaeological record represents a window onto the complex relationship between stone artefact variance and hominin behaviour. Differences in the shapes and sizes of stone flakes—the most abundant remains of past behaviours for much of human evolutionary history—may be underpinned by variation in a range of different environmental and behavioural factors. Controlled flake production experiments have drawn inferences between flake platform preparation behaviours, which have thus far been approximated by linear measurements, and different aspects of overall stone flake variability (Dibble and Rezek J Archaeol Sci 36:1945–1954, 2009; Lin et al. Am Antiq 724–745, 2013; Magnani et al. J Archaeol Sci 46:37–49, 2014; Rezek et al. J Archaeol Sci 38:1346–1359, 2011). However, when the results are applied to archaeological assemblages, there remains a substantial amount of unexplained variability. It is unclear whether this disparity between explanatory models and archaeological data is a result of measurement error on certain key variables, whether traditional analyses are somehow a general limiting factor, or whether there are additional flake shape and size drivers that remain unaccounted for. To try and circumvent these issues, here, we describe a shape analysis approach to assessing stone flake variability including a newly developed three-dimensional geometric morphometric method (‘3DGM’). We use 3DGM to demonstrate that a relationship between platform and flake body governs flake shape and size variability. Contingently, we show that by using this 3DGM approach, we can use flake platform attributes to both (1) make fairly accurate stone flake size predictions and (2) make relatively detailed predictions of stone flake shape. Whether conscious or instinctive, an understanding of this geometric relationship would have been critical to past knappers effectively controlling the production of desired stone flakes. However, despite being able to holistically and accurately incorporate three-dimensional flake variance into our analyses, the behavioural drivers of this variance remain elusive.     

Probable human hair found in a fossil hyaena coprolite from Gladysvale cave,South Africa

Until now, the oldest known human hair was from a 9000-year-old South American mummy. Here we report fossil hairs of probable human origin that exceed that age by about 200,000 years. The hairs have been discovered in a brown hyaena (Parahyaena brunnea) coprolite from Gladysvale cave in South Africa. The coprolite is part of a hyaena latrine preserved in calcified cave sediment dated between 195,000 and 257,000 years ago. This find supports the hypothesis that hyaenas accumulated some of the early hominin remains found in cave sites, and provides a new source of information on Pleistocene mammals in the Sterkfontein Valley.
