  • Animal personality: What are behavioural ecologists measuring? 

    Carter, Alecia J.; Feeney, WE; Marshall, Harry H.; Cowlishaw, Guy; Heinsohn, R (Wiley, 2013-05)

    A substantial amount of the atmospheric carbon taken up on land through photosynthesis and chemical weathering is transported laterally along the aquatic continuum from upland terrestrial ecosystems to the ocean. So far, ...
  • Antibiotic cycling versus mixing: the difficulty of using mathematical models to definitively quantify their relative merits. 

    Pena-Miller, R; Beardmore, Robert (American Institute of Mathematical Sciences, 2010-10)
    We ask the question Which antibiotic deployment protocols select best against drug-resistant microbes: mixing or periodic cycling? and demonstrate that the statistical distribution of the performances of both sets of ...
  • Anticipating ubiquitous computing: Logics to forecast technological futures 

    Kinsley, Samuel (Elsevier, 2011-03)
    Visions of the future predict spaces apparently teaming with ever more novel and pervasive technologies. Significant amongst such forecasts is the notion of ‘ubiquitous computing’ (ubicomp), understood as an affordance or ...
