The borderline personality concept has evolved from a term used to describe a neuroticpsychotic borderland (Knight 1963), or an almost but-not-quite schizophrenic process (Hock and Polatin 1949), to a more precise and operationally defined syndrome (American Psychiatric Association, 1980; Gunderson 1982). Affective changes are a major and consistent clinical feature in most descriptions of bord...

This paper will examine some commonly adopted approaches to the measurement of risk in finance and the various shortcomings implicit in the underpinnings of these approaches: early views on the nature of risk and uncertainty (Hume, Bernoulli, Knight, Keynes and Ramsey); the adoption of a mean variance decision choice criteria as a central foundation in financial economics and its accompanying l...

We introduce a family of planar regions, called Aztec diamonds, and study tilings of these regions by dominoes. Our main result is that the Aztec diamond of order n has exactly 2()/ domino tilings. In this, the first half of a two-part paper, we give two proofs of this formula. The first proof exploits a connection between domino tilings and the alternating-sign matrices of Mills, Robbins, and ...

Simply connected compact Kähler manifolds of dimension up to three with elliptic homotopy type are characterized in terms of their Hodge diamonds. This is applied to classify the simply connected Kähler surfaces and Fano threefolds with elliptic homotopy type.

In addition to the four grain size fractions of diamonds separated from the Efremovka (CV3) meteorite reported earlier [1], six more diamond size-fractions from the same meteorite have been generated with sizes both coarser and finer than the original set. Isotope analyses of C, N and noble gases in the new fractions confirmed most of the trends observed earlier for concentrations and isotopic ...

We introduce a family of planar regions, called Aztec diamonds, and study the ways in which these regions can be tiled by dominoes. Our main result is a generating function that not only gives the number of domino tilings of the Aztec diamond of order n but also provides information about the orientation of the dominoes (vertical versus horizontal) and the accessibility of one tiling from anoth...
