String Parton Models in Geant4
Dual parton and quark gluon string model are the by now almost standard
theoretical techniques by which one can arrive at precision description of high
energy, soft, inclusive reactions. These reactions make the part of jets at
energies that contribute strongly to discovery channels such as HWWjj, or
search for compositeness at the highest transverse momenta. The above modeling
approach is available with Geant4 for nucleon induced reactions since the first
release. Its object oriented design and parameter set was recently extended to
allow for simulation of pion and kaon induced reactions, as well as heavy ion
reactions. We will briefly describe the theory and algorithmic approaches that
underly the modeling, show the object oriented designs and component structure
of the string parton sub-systems of Geant4, present validation/verification
results pertaining to these models, as well as results concerning their usage
in calorimeter simulation.Comment: Computing in High Energy and Nuclear Physics, La Jolla, California,

Mediation Goes Mainstream - Taking the Conference Theme Challenge
Introduction to the Southern California Mediators Assiciation\u27s meeting, including a comment on the conference theme, mediation goes mainstream
The Geant4 Hadronic Verification Suite for the Cascade Energy Range
A Geant4 hadronic process verification suite has been designed to test and
optimize Geant4 hadronic models in the cascade energy range. It focuses on
quantities relevant to the LHC radiation environment and spallation source
targets. The general structure of the suite is presented, including the user
interface, stages of verification, management of experimental data, event
generation, and comparison of results to data. Verification results for the
newly released Binary cascade and Bertini cascade models are presented.Comment: Talk from the 2003 Computing in High Energy and Nuclear Physics

A persistent object manager for HEP
We propose to perform research in the area of a Persistant Object Manager for HEP. Persistant Objects are those which continue to exist upon process termination and may be accessed by other processes. It is expected that any system based upon this research will work primarily but not necessarily exclusively in an Object Oriented environment. Target applications include follow on or replacement products for existing packages such as GEANT, HEPDB, FATMEN, BHBOOK, experiment specific code event storage. In this respect, it is expected that more functionality will be required than simple persistance. It will be one of the goals of the of the project to define this extra layer of functionality. Strong emphasis will be placed on the use of standards and/or existing solutions wherever possible

Assimilative, Autonomous, or Synergistic Visions: How Mediation Programs in Florida Address the Dilemma of Court Connection
Over the past twenty-five years, the state of Florida has been recognized across the United States as a leader in the development of court-connected alternative dispute resolution programs. Mediation, in particular, has flourished across the state, with one hundred eleven programs in place in family, civil, community, and dependency sectors. Administrative support and oversight for court-connected mediation programs are provided by The Florida Dispute Resolution Center (DRC) - the administrative arm of the Florida Supreme Court - housed within the Office of the State Courts Administrator. In collaboration with the DRC, we designed and conducted a benchmarking study of seven selected mediation programs in the family, civil and community sectors. Our focus in this article is on certain insights that emerged at the macro level regarding the very nature of court-connected mediation, as we analyzed and tried to develop explanations for our empirical findings. Specifically, we will address the fundamental value-based dilemma of court-connected mediation programs, three different approaches to addressing this dilemma through which mediation programs and the courts have forged their relationship in Florida, and some implications of these insights for practice and policy
Clarifying the Theoretical Underpinnings of Mediation: Implications for Practice and Policy
In this article we examine developments in explaining and understanding the when and why of mediation practice - from the lay theories that have informed much of the field, to Bush and Folger\u27s articulation of three distinct and coherent ideologically based theoretical frameworks: the problemsolving framework, the harmony framework, and the transformative framework. We then trace the development of the transformative framework since its articulation in 1994, and share the insights we have gained along the way regarding the impact of increasing theoretical clarity and differentiation in the mediation field. We conclude with a discussion of the implications of ideologically based theoretical distinctions for mediation practice and policy, and recommendations for a fresh, theoretically informed, approach to policy initiatives
Retaliation in the workplace: The role of distributive, procedural, and interactional justice.
The authors investigated the relationship between organizational justice and organizational retaliation behavior-adverse reactions to perceived unfairness by disgruntled employees toward their employer-in a sample of 240 manufacturing employees. Distributive, procedural, and interactional justice interacted to predict organizational retaliation behavior. A relation between distributive justice and retaliation was found only when there was low interactional and procedural justice. The 2-way interaction of distributive and procedural justice was observed only at a low level of interactional justice, and the 2-way interaction of distributive and interactional justice was observed only at a low level of procedural justice
Influence of damping on the excitation of the double giant resonance
We study the effect of the spreading widths on the excitation probabilities
of the double giant dipole resonance. We solve the coupled-channels equations
for the excitation of the giant dipole resonance and the double giant dipole
resonance. Taking Pb+Pb collisions as example, we study the resulting effect on
the excitation amplitudes, and cross sections as a function of the width of the
states and of the bombarding energy.Comment: 8 pages, 3 figures, corrected typo
