In an important paper, Charles Engel and John H. Rogers (1996) estimate the impact of an international border on price dispersion across US and Canadian cities. After controlling for distance and other factors, they conclude that the economic impact of the border between the United States and Canada is equivalent to shipping a good 75,000 miles (Engel and Rogers 1996, 1117, table 3). Numerous s...

Janet’s algorithm to create normal forms for systems of linear pdes is outlined and used as a tool to construct resolutions for finitely generated modules over polynomial rings over fields as well as over rings of linear differential operators with coefficients in a differential field. The main result is that a Janet basis for a module allows to read off a Janet basis for the syzygy module. Two...

The coordination of velum and oral gestures for English [n] is studied using real-time MRI movies to reconstruct vocal tract aperture functions. This technique allows for the examination of parts of the vocal tract otherwise inaccessible to dynamic imaging or movement tracking. The present experiment considers syllable onset, coda, and juncture geminate nasals and also addresses the effects of ...

EVEN THE CASUAL reader of Jung’s works recognises that the influence on analytical psychology of Janet’s writings must be significant. There is little that is tangible, however, apart from a few phrases, invariably quoted in French (above all, abaissement du niveau mental). My investigations into this matter have convinced me that a great deal of the misunderstanding which developed between Fre...
