OrderImbalance, Liquidity and Market Returns

Abstract: We focus on an intuitive measure of trading activity: the aggregate daily order imbalance, buy orders less sell orders, on the NYSE. Order imbalance increases following market declines and vice versa, which reveals that investors are contrarians in aggregate. Order imbalances in either direction, excess buy or sell orders, reduce liquidity. Market-wide returns are strongly affected by contemporaneous and lagged order imbalances. Market returns reverse themselves after high negative imbalance, large negative return days. Even after controlling for aggregate volume and liquidity, market returns are affected by order imbalance.

The global map for traumatic spinal cord injury epidemiology: update 2011, global incidence rate

Abstract: Study design:Literature reviewObjectives:Update the global maps for traumatic spinal cord injury (TSCI) and incorporate methods for extrapolating incidence dataSetting:An initiative of the International Spinal Cord Society (ISCoS) Prevention CommitteeMethods:A search of Medline/Embase was performed (1959-Jun/30/2011) Enhancement of data-quality 'zones' including individual data-ranking as well as integrating regression techniques to provide a platform for continued regional and global estimatesResults:A global-incident rate (2007) is estimated at 23 TSCI cases per million (179 312 cases per annum) Regional data are available from North America (40 per million), Western Europe (16 per million) and Australia (15 per million) Extrapolated regional data are available for Asia-Central (25 per million), Asia-South (21 per million), Caribbean (19 per million), Latin America, Andean (19 per million), Latin America, Central (24 per million), Latin America-Southern (25 per million), Sub-Saharan Africa-Central (29 per million), Sub-Saharan Africa-East (21 per million)Discussion:It is estimated that globally in 2007, there would have been between 133 and 226 thousand incident cases of TSCI from accidents and violence The proportion of TSCI from land transport is decreasing/stable in developed but increasing in developing countries due to trends in transport mode (transition to motorised transport), poor infrastructure and regulatory challenges TSCIs from low falls in the elderly are increasing in developed countries with ageing populations In some developing countries low falls, resulting in TSCI occur while carrying heavy loads on the head in young people In developing countries high-falls feature, commonly from trees, balconies, flat roofs and construction sites TSCI is also due to crush-injuries, diving and violenceConclusion:The online global maps now inform an extrapolative statistical model, which estimates incidence for areas with insufficient TSCI data The accuracy of this methodology will be improved through the use of prospective, standardised-data registriesSpinal Cord advance online publication, 26 February 2013; doi:101038/sc2012158 Language: en

Multimodality, resemiotization: extending the analysis of discourse as multi-semiotic practice

Abstract: This article has the following two overarching aims First, it traces the development of multimodal discourse analysis and sets out its main descriptive and analytical parameters; in doing so, the article highlights the specific advantages which the multimodal approach has to offer and exemplifies its application The article also argues that the hierarchical arrangement of different semiotics (in the way common sense construes this) should not be lost from sight Second, and related to this last point, the article will advance a complementary perspective to that of multimodality: resemiotization Resemiotization is meant to provide the analytical means for (1) tracing how semiotics are translated from one into the other as social processes unfold, as well as for (2) asking why these semiotics (rather than others) are mobilized to do certain things at certain times The article draws on a variety of empirical data to exemplify these two perspectives on visual communication and analysis
