A Teacher\u27s Trouble: Risk, Responsibility and Rebellion

What follows is an edited transcript of a session at the 1995 Annual Meeting of the Association of American Law Schools, held in New Orleans, Louisiana, January 7, 1995. The meeting was a joint plenary session of the AALS Section on Professional Responsibility and the Section on Clinical Legal Education. The meeting was planned and the role plays were written by Professors Margaret Martin Barry and Lisa Lerman of The Catholic University of America and Professor Homer La Rue of Howard University. The purpose of the program was to foster interaction among teachers of professional responsibility and clinical teachers about issues that arise in both clinical and non-clinical teaching. As Professor Sandy Ogilvy of Catholic University said in introducing the session, the planners wanted to bring together the perspective on the profession of the professional responsibility teachers, with the expertise in teaching methodology of the clinicians, with the thought that each group would be interested in what the other group had to say. Interesting ethical issues arise daily in clinical programs, and the planners wanted to encourage cross-fertilization between these two fields and increased collaboration within law schools between clinical teachers and teachers of professional responsibility. In developing the three role plays presented in this program, the planners selected issues that raise ethical or professional dilemmas for the law teachers as well as for their students. The transcript of this discussion explores only some of the issues potentially raised by the role play scenarios. The editors of the Clinical Law Review invite readers to submit commentary reacting to the issues raised in this discussion, or raising other issues suggested by the role plays but not fully discussed by the participants. The Review will consider such submissions for possible publication in its next issue. Readers might also consider initiating further dialogue with colleagues through one of the relevant internet listservs (lawclinic, legalethics or lawprof); such dialogue also may be submitted for possible publication

Municipal Solid Waste Policy Forum : results and conclusions

1 v. (various pagings) : ill. ; 28 cm. includes bibliographical references.,from the abstract, . . .The Municipal Solid Waste Policy Forums are designed to bring together small groups of knowledgeable people to explore a wide range of municipal solid waste management issues. This particular Forum was designed for Long Island decision makers, specifically for town supervisors and their staffs. The objectives were (1) to present a clear, concise and well-balanced overview of the advantages and disadvantages, real and perceived, of modern resource recovery technology; (2) to explore other important components of a town\u27s comprehensive municipal solid waste management program; and (3) to examine the course we have embarked upon for municipal solid waste management on Long Island, to assess our present position relative to the goal, and to determine whether any mid-course corrections are called for. This report summarizes those major findings and recommendations which emerged from the discussion which are particularly pertinent to Long Island and the Metropolitan New York City area. .

Status Report of the DPHEP Study Group: Towards a Global Effort for Sustainable Data Preservation in High Energy Physics

Data from high-energy physics (HEP) experiments are collected with significant financial and human effort and are mostly unique. An inter-experimental study group on HEP data preservation and long-term analysis was convened as a panel of the International Committee for Future Accelerators (ICFA). The group was formed by large collider-based experiments and investigated the technical and organisational aspects of HEP data preservation. An intermediate report was released in November 2009 addressing the general issues of data preservation in HEP. This paper includes and extends the intermediate report. It provides an analysis of the research case for data preservation and a detailed description of the various projects at experiment, laboratory and international levels. In addition, the paper provides a concrete proposal for an international organisation in charge of the data management and policies in high-energy physics

Measurement of the B0 Lifetime and Oscillation Frequency using B0->D*+l-v decays

The lifetime and oscillation frequency of the B0 meson has been measured using B0->D*+l-v decays recorded on the Z0 peak with the OPAL detector at LEP. The D*+ -> D0pi+ decays were reconstructed using an inclusive technique and the production flavour of the B0 mesons was determined using a combination of tags from the rest of the event. The results t_B0 = 1.541 +- 0.028 +- 0.023 ps, Dm_d = 0.497 +- 0.024 +- 0.025 ps-1 were obtained, where in each case the first error is statistical and the second systematic.Comment: 17 pages, 4 figures, submitted to Phys. Lett.

A Measurement of Rb using a Double Tagging Method

The fraction of Z to bbbar events in hadronic Z decays has been measured by the OPAL experiment using the data collected at LEP between 1992 and 1995. The Z to bbbar decays were tagged using displaced secondary vertices, and high momentum electrons and muons. Systematic uncertainties were reduced by measuring the b-tagging efficiency using a double tagging technique. Efficiency correlations between opposite hemispheres of an event are small, and are well understood through comparisons between real and simulated data samples. A value of Rb = 0.2178 +- 0.0011 +- 0.0013 was obtained, where the first error is statistical and the second systematic. The uncertainty on Rc, the fraction of Z to ccbar events in hadronic Z decays, is not included in the errors. The dependence on Rc is Delta(Rb)/Rb = -0.056*Delta(Rc)/Rc where Delta(Rc) is the deviation of Rc from the value 0.172 predicted by the Standard Model. The result for Rb agrees with the value of 0.2155 +- 0.0003 predicted by the Standard Model.Comment: 42 pages, LaTeX, 14 eps figures included, submitted to European Physical Journal

Search for the Standard Model Higgs Boson with the OPAL Detector at LEP

This paper summarises the search for the Standard Model Higgs boson in e+e- collisions at centre-of-mass energies up to 209 GeV performed by the OPAL Collaboration at LEP. The consistency of the data with the background hypothesis and various Higgs boson mass hypotheses is examined. No indication of a signal is found in the data and a lower bound of 112.7GeV/C^2 is obtained on the mass of the Standard Model Higgs boson at the 95% CL.Comment: 51 pages, 21 figure

Measurement of the Hadronic Photon Structure Function F_2^gamma at LEP2

The hadronic structure function of the photon F_2^gamma is measured as a function of Bjorken x and of the factorisation scale Q^2 using data taken by the OPAL detector at LEP. Previous OPAL measurements of the x dependence of F_2^gamma are extended to an average Q^2 of 767 GeV^2. The Q^2 evolution of F_2^gamma is studied for average Q^2 between 11.9 and 1051 GeV^2. As predicted by QCD, the data show positive scaling violations in F_2^gamma. Several parameterisations of F_2^gamma are in agreement with the measurements whereas the quark-parton model prediction fails to describe the data.Comment: 4 pages, 2 figures, to appear in the proceedings of Photon 2001, Ascona, Switzerlan
