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

Lecture archiving on a larger scale at the University of Michigan and CERN

The ATLAS Collaboratory Project at the University of Michigan has been a leader in the area of collaborative tools since 1999. Its activities include the development of standards, software and hardware tools for lecture archiving, and making recommendations for videoconferencing and remote teaching facilities. Starting in 2006 our group became involved in classroom recordings, and in early 2008 we spawned CARMA, a University-wide recording service. This service uses a new portable recording system that we developed. Capture, archiving and dissemination of rich multimedia content from lectures, tutorials and classes are increasingly widespread activities among universities and research institutes. A growing array of related commercial and open source technologies is becoming available, with several new products introduced in the last couple years. As the result of a new close partnership between U-M and CERN IT, a market survey of these products was conducted and a summary of the results are presented here. It is informing an ambitious effort in 2009 to equip many CERN rooms with automated lecture archiving systems, on a much larger scale than before. This new technology is being integrated with CERN's existing webcast, CDS, and Indico applications.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/85420/1/jpconf10_219_082003.pd

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 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

A measurement of the tau mass and the first CPT test with tau leptons

We measure the mass of the tau lepton to be 1775.1+-1.6(stat)+-1.0(syst.) MeV using tau pairs from Z0 decays. To test CPT invariance we compare the masses of the positively and negatively charged tau leptons. The relative mass difference is found to be smaller than 3.0 10^-3 at the 90% confidence level.Comment: 10 pages, 4 figures, Submitted to Phys. Letts.

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
