No full textThis article explores the cultural meanings of file sharing and other forms of digital media piracy in Ukraine. Ukraine, the second most populous of the former Soviet republics, had been named as one of the ten “priority countries ” with “unacceptable piracy rates”. Western governments and commercial associations have lobbied intensively to present piracy in straightforward terms as a crime. In contrast, the author argues that file sharing practices in Ukraine reflect distinctive features of its cultural heritage. Two factors are particularly important here: the Soviet Union’s disregard for international copyright norms and the cultural tradition of Samizdat that arose as a form of cultural resistance to the state’s monopoly on conventional reproductive methods. Samizdat was closely tied to the emergence of a modern Ukrainian national identity. An analysis of current Ukrainian attitudes toward piracy, focused on users of the popular Muzon.com music sharing site, shows that these factors influence attitudes toward the legitimacy of international copyright measures. Many Ukrainians distrust the imposition of controls on reproduction of information and resent the coercive tactics used against local pirate producers on behalf of Western copyright holders. Parallels between file sharing and Samizdat are particularly instructive because both take place from one individual to another along an anonymous chain, across national boundaries, and without the control of copyright holders. In both cases the political meaning of the action comes from participation in the process itself, as much as from the material being shared.

3D nonlinear dynamic Finite Element analysis of onshore wind turbines on pile foundation resting on liquefiable soils
No full textThe latest development of wind turbines in seismic areas, such as East Asia and Californian coast, has increased the importance of their seismic design. High-intensity ground motions can strongly affect serviceability of wind turbines due to earthquake-induced settlements and rotations. In the presence of loose, saturated sandy soils, liquefaction may also become a concern. In such circumstances cyclic soil behaviour needs to be carefully simulated by considering coupled u-p formulations. In this paper, the main results of fully-coupled Finite Element nonlinear dynamic 3D analyses are discussed, where a typical onshore wind turbine on a piled raft foundation resting on liquefiable soils, with piles penetrating into dense sand, is subjected to high-intensity motions triggering liquefaction. Soil behaviour was described through the constitutive model SANISAND. The numerical results were compared to those obtained through a reduced-scale model tested in the centrifuge available at University of Cambridge, thus providing useful insight on the efficacy and reliability of 3D numerical modelling of such systems, which is anticipated to become more and more common in the near future
Large-scale forcing of the European Slope Current and associated inflows to the North Sea
No full textDrifters drogued at 50?m in the European Slope Current at the Hebridean shelf break follow a wide range of pathways, indicating highly variable Atlantic inflow to the North Sea. Slope Current pathways, timescales and transports over 1988–2007 are further quantified in an eddy-resolving ocean model hindcast. Particle trajectories calculated with model currents indicate that Slope Current water is largely ''recruited'' from the eastern subpolar North Atlantic. Observations of absolute dynamic topography and climatological density support theoretical expectations that Slope Current transport is to first order associated with meridional density gradients in the eastern subpolar gyre, which support a geostrophic inflow towards the slope. In the model hindcast, Slope Current transport variability is dominated by abrupt 25–50?% reductions of these density gradients over 1996–1998. Concurrent changes in wind forcing, expressed in terms of density gradients, act in the same sense to reduce Slope Current transport. This indicates that coordinated regional changes of buoyancy and wind forcing acted together to reduce Slope Current transport during the 1990s. Particle trajectories further show that 10–40?% of Slope Current water is destined for the northern North Sea within 6 months of passing to the west of Scotland, with a clear decline in this Atlantic inflow over 1988–2007. The influence of variable Slope Current transport on the northern North Sea is also expressed in salinity, which declines through the hindcast period, and there is evidence for a similar freshening trend in observational records. A proxy for Atlantic inflow may be found in sea level records. Variability of Slope Current transport is implicit in mean sea level differences between Lerwick (Shetland) and Torshavn (Faeroes), in both tide gauge records and a longer model hindcast spanning 1958–2013. Potential impacts of this variability on North Sea biogeochemistry and ecosystems, via associated changes in seasonal stratification and nutrient fluxes, are discussed
LEAP-UCD-2017 Centrifuge Tests at Cambridge
No full textAs part of the LEAP project the seismic response of a liquefiable 5° slope was modelled at a number of centrifuges around the world. In this paper the two experiments conducted at Cambridge University are discussed. The model preparation is detailed with particular emphasis on the sand pouring, saturation and slope cutting process. The presence of the third harmonic in the input motion is shown and its significance discussed. The potential for wavelet denoising to filter random electrical noise from the pore pressure traces is illustrated. CPT strength profiles are highlighted and a possible softer layer in one of the tests is discussed. Whilst the specifications called for one dense and one loose test, the likelihood that both Cambridge tests were loosely poured is assessed. The PIV technique is used to obtain the displacements of the slope during the test. Finally, the correspondence between the PIV displacements and physical measurements of the marker movements is compared
Heat and light
No full textBestselling author Jennifer Haigh returns to the Pennsylvania town and the conflicting forces at its heart - hope and desperation, greed and power, big business and small-town families. Forty years ago, Bakerton coal fueled the country. Then the mines closed, and the town wore away. Now Bakerton has been granted a surprise third act: it sits squarely atop the Marcellus Shale, a massive deposit of natural gas. Told through a cast of characters whose lives are increasingly bound by the opposing interests that underpin the national debate, this novel depicts a community blessed and cursed by its natural resource
Beyond Peter Rabbit : the private life of Beatrix Potter
No full textMichigan State University Humanities Librarian Agnes Haigh Widder delivers a talk entitled, "Beyond Peter Rabbit: The Private Life of Beatrix Potter." Showing examples of Potter's work, Widder discusses the personality and life of Potter and says that she was much more than the storied, brilliant and eccentric author. Widder explains that Potter was a naturalist, farmer, scientific illustrator, stockbreeder, and influential conservationist in England's Lake District, then comments on Potter's coded diary, her life, work, and legacy. She answers questions from the audience. Widder is introduced by John D. Shaw from the G. Robert Vincent Voice Library. Part of the Michigan State University Libraries' Colloquia Series. Held at the MSU Main Library
Mapping Agricultural Decision Making across the U.S. Corn Belt
No full textDecision calendars help identify opportunities for inserting climate information into a decision process as well as points where other considerations might overrule use of the climate information. Developers of decision calendars are challenged, though, by a potentially infinite number of modifications required to address spatial variability in agricultural decision making. Variability in climate, soils, and agricultural production systems across a region may result in deviations in decision-making times.This poster is published as Haigh, Tonya, Eugene Takle, Jeffrey Andresen, Melissa Widhalm, J.
