Social Links from Latent Topics in Microblogs

Language use is overlaid on a network of social con-nections, which exerts an influence on both the top-ics of discussion and the ways that these topics can be expressed (Halliday, 1978). In the past, efforts t

I Knew There Was Something Wrong with That Paper : Scientific Rhetorical Styles and Scientific Misunderstandings

This selection unpacks scientific prose and claim substantiation for Nobel Prize winner, Stan Prusiner, in the transmissible spongiform encephlopathies field (i.e., mad cow disease). Applying linguistic strategies such as M. A. K. Halliday\u27s favorite clause type, the author examines argumentative strategies in dense scientific prose both in bold and cautious rhetorical styles and invented lexical changes in new scientific development

Exercise “Musk Ox”: Asserting Sovereignty “North of 60”

The Second World War was over and the Canadian armed forces were being reduced rapidly. The first chilly blasts of the Cold War had not yet penetrated to the consciousness of most Canadians. What role could the forces play in the postwar world? The most obvious answer was to revert to those interwar operations that had most directly benefited the nation—aerial surveys, northern communications, limited engineering projects. New tasks had evolved; aerial search and rescue was an example. The Canadian government was aware that it had neglected the north during the war; the American presence in the Alaska Highway, CANOL, and aerial delivery routes via the Arctic had been more prominent than that of the nominal owners of the region. This was continuing even into the postwar period; early in 1946 the USS Midway was cruising in the Labrador Sea and Davis Strait areas, experiencing Arctic flying conditions and noting the effects of sub-zero temperatures on carrier-borne aircraft. “Musk Ox,” publicly described as a test of military equipment and capabilities in the north, was a gesture to reassert Canadian sovereignty “north of 60.

A Cluster Algorithm for the Z2Z_2 Kalb-Ramond Model

A cluster algorithm is presented for the $Z_2$ Kalb-Ramond plaquette model in four dimensions which dramatically reduces critical slowing. The critical exponent $z$ is reduced from $z>2$ (standard Metropolis algorithm) to $z= 0.32\pm0.06$. The Cluster algorithm updates the monopole configuration known to be responsible for the second order phase transition.Comment: 9 pages, LaTeX + 7 figures in self-extracting shell archiv

Drawing the Representation

This article argues that the Representation is drawn by the perceiver: that it does not arrive at the visual cortex fully-formed. Rather, colour arrives at the visual cortex and the Representation is drawn from that

Mismeasured Household Size and Its Implications for the Identification of Economies of Scale

We consider the possibility that demographic variables are measured with errors which arise because household surveys measure demographic structures at a point-in-time, whereas household composition evolves throughout the survey period. We construct and estimate sharp bounds on household size and find that the degree of these measurement errors is non-trivial. However, while these errors have the potential to resolve the Deaton-Paxson paradox, they fail to do so.migration, measurement error, semi-parametric bounds, economies of scale
