Linguists, including computational linguists, have always been fond of talking about trees. In this paper, we outline a theory of linguistic structure which talks about talking about trees; we call this theory Description theory (D-theory). While important issues must be resolved before a complete picture of D-theory emerges (and also before we can build programs which utilize it), we believe t...

Two studies examined misperceptions of disagreement in partisan social conflicts, namely, in the debates over abortion (Study 1) and politics (Study 2). We observed that partisans tend to exaggerate differences of opinion with their adversaries. Further, we found that perceptions of disagreement were more pronounced for values that were central to the perceiver’s own ideology than for values th...

This paper draws on the experiences of the author during the past fifteen years of working primarily with school, college, university and health librarians, but with occasional forays into the public and special library domains. It is written by an educationalist and teacher trainer with an interest in library development; someone who has never run a library but who has researched into them and...

An affine vertex operator construction at arbitrary level is presented which is based on a completely compactified chiral bosonic string whose momentum lattice is taken to be the (Minkowskian) affine weight lattice. This construction is manifestly physical in the sense of string theory, i.e., the vertex operators are functions of DDF “oscillators” and the Lorentz generators, both of which commu...

Over the last decade or so, a good deal of effort has been put into the development of software engineering tools, and both CASE (Computer Aided Software Engineering) and, to a lesser extent, IPSEs (Integrated Project Support Environments) have received a good deal of attention. Although the tools used by many designers and programmers building business applications have changed significantly, ...

BACKGROUND Clinicians commonly rely on tertiary drug information references to guide drug dosages for patients who are receiving continuous renal replacement therapy (CRRT). It is unknown whether the dosage recommendations in these frequently used references reflect the most current evidence. OBJECTIVE To determine the presence and accuracy of drug dosage recommendations for patients undergoi...

Antibiotic resistance tends to increase when a patent on an antibiotic expires. Since other companies can now sell the antibiotic, more of the antibiotic is produced and prices fall. Because the benefits of reducing current production go to other firms, pharmaceutical companies will have little concern about future resistance. This 'open-access' problem causes excessive antibiotic use and resis...

A Borel-Tits theory was developped for almost split forms of symmetrizable Kac-Moody Lie algebras [J. of Algebra 171, 43-96 (1995)]. In this paper, we look to almost split real forms for symmetrizable hyperbolic KacMoody Lie algebras and we establish a complete list of these forms, in terms of their Satake-Tits index, for the strictly hyperbolic ones and for those which are obtained as (hyperbo...
