    The Juvenile Justice and Delinquency Prevention Act (JJDPA) mandates removal of status offenders and nonoffenders from secure detention and correctional facilities, sight and sound separation of juveniles and adults, and removal of juveniles from adult jails and lockups. In Alaska, no instances of a status offender held in secure detention were recorded in 1990, as compared with 485 violations in the baseline year of 1976. 135 separation violations were recorded in 1990, representing an 84% reduction from the 1976 baseline and 60% from 1989. 99 jail removal violations occurred, representing a 89% reduction from the 1980 baseline and an 60% reduction from 1989.Alaska Department of Health and Social Services, Division of Family and Youth ServicesA.

    Alaska as a Case Study of OJJDP-Mandated Jail Monitoring

    Get PDF
    The Office of Juvenile Justice and Delinquency prevention has mandated that all states monitor jail records for the presence of juveniles and inspect jails and lock-ups in which juveniles might be detained for sight and sound separation. The experience of Alaska in complying with this mandate is instructive. In the largest state in the union 99 facilities in a monitoring universe of 111 (89.1 %) are accessible only by air or water. Alaska's jail monitoring plan accommodated this inaccessibility. The plan and 1989 monitoring activities are explained and discussed. As the largest state in the Union Alaska has had some unique problems complying with the mandate of the Juvenile Justice and Delinquency Act to monitor secure facilities for the presence of juveniles. In spite of these problems Alaska has produced a model monitoring plan and has successfully completed three years of compliance monitoring activities. The monitoring process and the problems associated with monitoring activities are useful for other states to consider as they review their monitoring plans.Abstract / Introduction / Jail Monitoring in Alaska / Special Problems / Discussion / References / FIGURES / Figure 1.

    1989 Juvenile Justice and Delinquency Prevention Act Compliance Monitoring Report

    The Juvenile Justice and Delinquency Prevention Act (JJDPA) mandates removal of status offenders and nonoffenders from secure detention and correctional facilities, sight and sound separation of juveniles and adults, and removal of juveniles from adult jails and lockups. In Alaska, two instances of a status offender held in secure detention were recorded in 1989; but both satisfied the "valid court order" exception, so were not counted as violations; by comparison, there were 485 violations in the baseline year of 1976. 336 separation violations were recorded in 1989, representing a 60% reduction from the 1976 baseline and 41% from 1988. 249 jail removal violations occurred, representing a 71% reduction from the 1980 baseline and an 39% reduction from 1988.Alaska Department of Health and Social Services, Division of Family and Youth ServicesA.

    Student experiences of technology integration in school subjects: A comparison across four middle schools

    This research examined student perspectives on their in-school, subject specific, technology use in four U.S. public schools. Considering students’ perspectives may provide a significant reframing of adult-created rhetoric of the utopian power of digital technologies for changing teaching and learning. A survey and focus group interviews were administered to 6th and 7th students (n=1,544) in four public middle schools, with varying demographics, that rely on local funding. These four schools revealed moderate use of many well-established digital technologies, such as word processing, presentation software, and quiz games. Students voiced outright hatred for teacher-directed PowerPoint-supported lectures, the most prominent technology activity students experienced, yet reported enjoying creation activities. The students in the rural school with a Hispanic-majority and high economically disadvantaged population reported much lower technology use. Discussion frame the digital inequities in the four schools and emphasizes the need for awareness and inclusion of students’ digital experiences to form any trajectory toward establishing digital equity and learning in schools

    Wavefunctions and counting formulas for quasiholes of clustered quantum Hall states on a sphere

    Full text link
    The quasiholes of the Read-Rezayi clustered quantum Hall states are considered, for any number of particles and quasiholes on a sphere, and for any degree k of clustering. A set of trial wavefunctions, that are zero-energy eigenstates of a k+1-body interaction, and so are symmetric polynomials that vanish when any k+1 particle coordinates are equal, is obtained explicitly and proved to be both complete and linearly independent. Formulas for the number of states are obtained, without the use of (but in agreement with) conformal field theory, and extended to give the number of states for each angular momentum. An interesting recursive structure emerges in the states that relates those for k to those for k-1. It is pointed out that the same numbers of zero-energy states can be proved to occur in certain one-dimensional models that have recently been obtained as limits of the two-dimensional k+1-body interaction Hamiltonians, using results from the combinatorial literature.Comment: 9 pages. v2: minor corrections; additional references; note added on connection with one-dimensional Hamiltonians of recent interes

    Non-Abelian spin-singlet quantum Hall states: wave functions and quasihole state counting

    Full text link
    We investigate a class of non-Abelian spin-singlet (NASS) quantum Hall phases, proposed previously. The trial ground and quasihole excited states are exact eigenstates of certain k+1-body interaction Hamiltonians. The k=1 cases are the familiar Halperin Abelian spin-singlet states. We present closed-form expressions for the many-body wave functions of the ground states, which for k>1 were previously defined only in terms of correlators in specific conformal field theories. The states contain clusters of k electrons, each cluster having either all spins up, or all spins down. The ground states are non-degenerate, while the quasihole excitations over these states show characteristic degeneracies, which give rise to non-Abelian braid statistics. Using conformal field theory methods, we derive counting rules that determine the degeneracies in a spherical geometry. The results are checked against explicit numerical diagonalization studies for small numbers of particles on the sphere.Comment: 17 pages, 4 figures, RevTe

    Non-Abelian quantized Hall states of electrons at filling factors 12/5 and 13/5 in the first excited Landau level

    Full text link
    We present results of extensive numerical calculations on the ground state of electrons in the first excited (n=1) Landau level with Coulomb interactions, and including non-zero thickness effects, for filling factors 12/5 and 13/5 in the torus geometry. In a region that includes these experimentally-relevant values, we find that the energy spectrum and the overlaps with the trial states support the previous hypothesis that the system is in the non-Abelian k = 3 liquid phase we introduced in a previous paper.Comment: 5 pages (Revtex4), 7 figure

    Development and verification of design methods for ducts in a space nuclear shield

    Get PDF
    A practical method for computing the effectiveness of a space nuclear shield perforated by small tubing and cavities is reported. Performed calculations use solutions for a two dimensional transport code and evaluate perturbations of that solution using last flight estimates and other kernel integration techniques. In general, perturbations are viewed as a change in source strength of scattered radiation and a change in attenuation properties of the region
