    In 2014 Nebraska took a giant step toward fixing pervasive issues plaguing agencies throughout the justice system culminating in a prison system that was bursting at the seams. The state enlisted the services of the Council of State Governments (CSG), a national organization dedicated to helping state governments problem-solve and develop policies for the common good. Over the next several years, the CSG worked to help Nebraska usher in policies that would begin to shape justice reinvestment in the state. Along with the CSG’s initial assessment procedures, the Nebraska Department of Correctional Services (NDCS) asked the group to do an additional review of its institutional programming. The report, released in June of 2016, drove home what many of us who had been working to implement programming within the Department had already experienced: not enough staff to run programs and not enough assessment procedures and training in place to ensure programs are running well. The report also detailed a number of recommendations for NDCS, which included providing more efficient and effective programming. We were delighted to see the effort we had given to specific areas of Transformation Project curriculum and implementation matched perfectly with the CSG’s recommendations. By working to address multiple criminogenic needs at once, building proficiency by integrating graduated skills practice and utilizing gender and youth specific curriculum, Transformation Project is ahead of the curve when it comes to comprehensive prison programming. Our attention to incorporating fidelity measures is also right on target to help overcome some of the issues faced by corrections systems as they work to implement programming. This is reassuring as we develop a program that fits the needs of Nebraska and meets high national standards

    The Transformation Project: 2014 Annual Report

    For years debate has rumbled in this country over prison overcrowding. More recently, there has been an additional spotlight on issues that are exacerbated when prisons are over capacity, such as prison rape and the use of restrictive housing (housing inmates in isolated conditions). In the case of prison rape, federal standards have been placed on institutions through the passage of the Prison Rape Elimination Act (PREA). General consensus among corrections professionals is that a lack of internal action diminished their voice during the creation of the PREA standards. There is consequently a large motivation for correctional institutions to work to address concerns regarding restrictive housing. Groups like Amnesty International, the American Civil Liberties Union and the Association of State Correctional Administrators have all been contributing to this effort by each creating their own guidelines for using restrictive housing. 2014 was a great opportunity for us to reflect on how Transformation Project (TP) will benefit institutions as they look to revise how they house inmates that are a threat to themselves or others. Not only does TP provide programming for restrictive housing, where there has historically been a dearth of programming, it works to increase the amount and quality of interaction between staff and participants, as well as provide a measure for assessing progress in restrictive housing. All of these efforts are included in the recommendations across invested organizations, adding additional value to TP curriculum. In addition to strengthening TP in restrictive housing, this year we began exploring ways the program can be modified for use in a women’s facility. While there is much work to be done in this area, we are excited to bring adaptions to the curriculum that will specifically address the needs of justice involved women. We look forward to continuing the development process with our partners at the Nebraska Correctional Center for Women in York, Nebraska, as this group has been instrumental to providing essential expertise and feedback. As debates around corrections issues roll on, in the coming months we look forward to solidifying TP’s role in the rehabilitation of inmates throughout the course of their incarceration

    Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

    A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

    Measurement of the dependence of transverse energy production at large pseudorapidity on the hard-scattering kinematics of proton-proton collisions at √s=2.76 TeV with ATLAS

    Get PDF
    The relationship between jet production in the central region and the underlying-event activity in a pseudorapidity-separated region is studied in 4.0 pb-1 of s=2.76 TeV pp collision data recorded with the ATLAS detector at the LHC. The underlying event is characterised through measurements of the average value of the sum of the transverse energy at large pseudorapidity downstream of one of the protons, which are reported here as a function of hard-scattering kinematic variables. The hard scattering is characterised by the average transverse momentum and pseudorapidity of the two highest transverse momentum jets in the event. The dijet kinematics are used to estimate, on an event-by-event basis, the scaled longitudinal momenta of the hard-scattered partons in the target and projectile beam-protons moving toward and away from the region measuring transverse energy, respectively. Transverse energy production at large pseudorapidity is observed to decrease with a linear dependence on the longitudinal momentum fraction in the target proton and to depend only weakly on that in the projectile proton. The results are compared to the predictions of various Monte Carlo event generators, which qualitatively reproduce the trends observed in data but generally underpredict the overall level of transverse energy at forward pseudorapidity

    Measurement of W boson angular distributions in events with high transverse momentum jets at s√= 8 TeV using the ATLAS detector

    Get PDF
    The W boson angular distribution in events with high transverse momentum jets is measured using data collected by the ATLAS experiment from proton–proton collisions at a centre-of-mass energy at the Large Hadron Collider, corresponding to an integrated luminosity of . The focus is on the contributions to processes from real W emission, which is achieved by studying events where a muon is observed close to a high transverse momentum jet. At small angular separations, these contributions are expected to be large. Various theoretical models of this process are compared to the data in terms of the absolute cross-section and the angular distributions of the muon from the leptonic W decay.Fil: Aaboud, M..

    The decays B-c(+) -> J/psi D-s(+) and B-c(+) -> J/psi D-s*(+) are studied with the ATLAS detector at the LHC using a dataset corresponding to integrated luminosities of 4.9 and 20.6 fb(-1) of pp collisions collected at centre-of-mass energies root s = 7 TeV and 8 TeV, respectively. Signal candidates are identified through J/psi -> mu(+)mu(-) and D-s(()*()+) -> phi pi(+)(gamma/pi(0)) decays. With a two-dimensional likelihood fit involving the B-c(+) reconstructed invariant mass and an angle between the mu(+) and D-s(+) candidate momenta in the muon pair rest frame, the yields of B-c(+) -> J/psi D-s(+) and B-c(+) -> J/psi D-s*(+), and the transverse polarisation fraction in B-c(+) -> J/psi D-s*(+) decay are measured. The transverse polarisation fraction is determined to be Gamma +/-+/-(B-c(+) -> J/psi D-s*(+))/Gamma(B-c(+) -> J/psi D-s*(+)) = 0.38 +/- 0.23 +/- 0.07, and the derived ratio of the branching fractions of the two modes is B-Bc+ -> J/psi D-s*+/B-Bc+ -> J/psi D-s(+) = 2.8(-0.8)(+1.2) +/- 0.3, where the first error is statistical and the second is systematic. Finally, a sample of B-c(+) -> J/psi pi(+) decays is used to derive the ratios of branching fractions B-Bc+ -> J/psi D-s*+/B-Bc+ -> J/psi pi(+) = 3.8 +/- 1.1 +/- 0.4 +/- 0.2 and B-Bc+ -> J/psi D-s*+/B-Bc+ -> J/psi pi(+) = 10.4 +/- 3.1 +/- 1.5 +/- 0.6, where the third error corresponds to the uncertainty of the branching fraction of D-s(+) -> phi(K+ K-)pi(+) decay. The available theoretical predictions are generally consistent with the measurement
