A Combined System for Update Logic and Belief Revision

Revised Selected PapersInternational audienceIn this paper we propose a logical system combining the update logic of A. Baltag, L. Moss and S. Solecki (to which we will refer to by the generic term BMS, [BMS04]) with the belief revision theory as conceived by C. Alchourron, P. Gardenfors and D. Mackinson (that we will call the AGM theory, [GardRott95]) viewed from the point of view of W. Spohn ( [Spohn90], [Spohn88]). We also give a proof system and a comparison with the AGM postulates

Normal Heat Conductivity in a strongly pinned chain of anharmonic oscillators

We consider a chain of coupled and strongly pinned anharmonic oscillators subject to a non-equilibrium random forcing. Assuming that the stationary state is approximately Gaussian, we first derive a stationary Boltzmann equation. By localizing the involved resonances, we next invert the linearized collision operator and compute the heat conductivity. In particular, we show that the Gaussian approximation yields a finite conductivity $\kappa\sim\frac{1}{\lambda^2T^2}$, for $\lambda$ the anharmonic coupling strength.Comment: Introduction and conclusion modifie

The Douglas County Drug Court: Characteristics Of Participants, Case Outcomes And Recidivism

The purpose of this report is to describe the characteristics of all offenders (N = 255) who were bound over to Douglas County District Court in 2001 and who were subsequently diverted to the Douglas County Drug Court. We present descriptive data on the characteristics of the drug court participants, focusing on their background characteristics and prior criminal record and on their case characteristics. We also present descriptive data on recidivism for drug court participants and for traditionally adjudicated offenders and compare the recidivism rates of these two groups of offenders, controlling for other predictors of the likelihood of recidivism

Cost/Benefit Analysis of the Douglas County Drug Court

The primary purpose of this cost-benefit evaluation of the Douglas County Drug Court (DCDC) is to provide administrators and policy-makers with critical information for future policy and funding decisions. This study expands and refines previous DCDC cost-benefit analyses through an investigation of drug court program investment, outcome and societal-impact costs and savings. This study employs a Transaction Cost model that examines complex, multi-agency events and costs for participants in drug court and non-drug court comparison groups. A “cost-to-taxpayer” approach is used that includes any criminal justice related costs (or avoided costs) generated by drug court or non-drug court comparison group participants, that directly impacts citizens either through tax-related expenditures or personal victimization costs/losses due to crimes committed by drug offenders

Felony Offenses In Douglas County District Court, 2001

The purpose of this report is describe the offender and case characteristics and the outcomes of all felony cases (N = 2,663) bound over for trial in Douglas County (Nebraska) District Court in 2001.1 We present descriptive data on these cases, focusing on defendants’ background characteristics and prior criminal record, the nature and seriousness of the charges for which the defendant was bound over to District Court, the disposition of the case, and case processing time. We also examine case dispositions and sentences for 15 different types of felony offenses and present descriptive data and case outcome data for defendants who were held in custody prior to trial and for non-violent defendants who were charged with property crimes (burglary, theft, fraud, and forgery). In the final section of the report we provide information on case characteristics and case outcomes for white and black defendants and for male and female defendants

A numerical approach to large deviations in continuous-time

We present an algorithm to evaluate the large deviation functions associated to history-dependent observables. Instead of relying on a time discretisation procedure to approximate the dynamics, we provide a direct continuous-time algorithm, valuable for systems with multiple time scales, thus extending the work of Giardin\`a, Kurchan and Peliti (PRL 96, 120603 (2006)). The procedure is supplemented with a thermodynamic-integration scheme, which improves its efficiency. We also show how the method can be used to probe large deviation functions in systems with a dynamical phase transition -- revealed in our context through the appearance of a non-analyticity in the large deviation functions.Comment: Submitted to J.
