Semi-Inclusive DIS and Transversity

A review is presented of some aspects of semi-inclusive deeply inelastic scattering and transversity. In particular, the role of $k_T$-dependent and higher-twist (or multi-parton) distributions in generating single-spin asymmetries is discussed.Comment: 8 pages, uses aipproc.cls, feynmp, psfrag, and some personal packages (included); invited talk presented at HiX 2004, Marseille, 26-28 July 200

Single-Spin Asymmetries and Transversity

A pedagogical introduction to single-spin asymmetries (SSA's) and transversity is presented. Discussion in some detail is made of certain aspects of (SSA's) in lepton-nucleon and in hadron-hadron scattering and the role of pQCD and evolution in the context of transversity.Comment: 10 pages, 11 figures, presented at the XV International Symposium on High-Energy Spin Physics (Brookhaven, 9-14 Aug. 2002

The Summary Affirmance Proposal of the Board of Immigration Appeals

The Board of Immigration Appeals is on the verge of making a tragic mistake, trading away a key element of fair adjudication--the written opinion--for the sake of what it hopes will be greater administrative efficiency. The cost of eliminating written adjudication is too great, and the Board has given no indication that it has sufficiently canvassed less drastic alternatives. The Board of Immigration Appeals (the Board ) is the primary appellate body for immigration law. The staple of its work is to decide appeals from decisions of Immigration Judges in removal proceedings, though it also hears appeals in several other categories, such as decisions of Immigration Judges on petitions for approval of preferred immigration status by virtue of close relationship to a United States citizen or permanent alien

Working Papers as Federal Records: The Need for New Legislation to Preserve the History of National Policy

This article deals with policy records at the front end of their lives; that is, preserving them from destruction by federal agencies in the decades immediately after their creation. It does not deal with the destruction of archived documents by Archives officials themselves. It discusses only in passing the related question of how long a policy record should be sealed off from public inspection; the literature includes a variety of opinions on that subject. The author is content to leave to others the problem of just where to draw the balance between making historical documentation available soon enough so that it can offer relevant lessons to citizens, but not so soon as to discourage officials from putting their candid thoughts and recommendations on paper or disk, for fear of public exposure and pressure. He focuses, instead, on the preservation of governmental records, and particularly of drafts, comments, and other working papers. Of course the issues of preservation and access are intimately linked: if records are routinely destroyed as soon as they are no longer needed by their creators, public access-even much delayed public access-becomes altogether impossible

QCD and Transverse-Spin Physics

A pedagogical presentation of single-spin asymmetries and transversity is offered. Detailed discussion is given of various aspects of single-spin asymmetries in lepton-nucleon and in hadron-hadron scattering and of the role of perturbative QCD and evolution in the context of transversity.Comment: Talk at the International Workshop on QCD: QCD@Work 2003 - Conversano (Italy) 14-18 June 2003 (eConf C030614). LaTeX2e; 8 pages; uses standard LaTeX macros (including psfrag), conference class file wqcd03.cls, and some personal macros (included). Figures are eps and feynmp generated (included in subfolders

Collaboration on reference to objects that are not mutually known

In conversation, a person sometimes has to refer to an object that is not previously known to the other participant. We present a plan-based model of how agents collaborate on reference of this sort. In making a reference, an agent uses the most salient attributes of the referent. In understanding a reference, an agent determines his confidence in its adequacy as a means of identifying the referent. To collaborate, the agents use judgment, suggestion, and elaboration moves to refashion an inadequate referring expression.Comment: 6 pages, to appear in proceedings of COLING-94, LaTeX (now uses fullname.sty, fullname.bst
