Hadron Spectroscopy with COMPASS at CERN
The aim of the COMPASS hadron programme is to study the light-quark hadron
spectrum, and in particular, to search for evidence of hybrids and glueballs.
COMPASS is a fixed-target experiment at the CERN SPS and features a two-stage
spectrometer with high momentum resolution, large acceptance, particle
identification and calorimetry. A short pilot run in 2004 resulted in the
observation of a spin-exotic state with consistent with the
debated . In addition, Coulomb production at low momentum transfer
data provide a test of Chiral Perturbation Theory. During 2008 and 2009, a
world leading data set was collected with hadron beam which is currently being
analysed. The large statistics allows for a thorough decomposition of the data
into partial waves. The COMPASS hadron data span over a broad range of channels
and shed light on several different aspects of QCD.Comment: 4 pages, 5 figure
Strengths Model for Youth: Moving toward a Client-Centered, Strengths-based Model of Case Management in Community Mental Health
Approximately 13 to 20% of U.S. children and adolescents experience a mental disorder in a given year (Perou et al., 2013), with only half of these youth receiving mental health care (Kataoka, Zhang, & Wells, 2002; Merikangas, Nakamura, & Kessler, 2009). Even when children do access mental health services, approximate- ly 40% to 60% discontinue before completing their treatment (Baruch, Vrouva, & Fearon, 2009; Hoste, Zaitsoff, Hewell & le Grange, 2007; Miller, Southam-Gerow & Allin, 2008; Oruche, Downs, Holloway, Draucker & Aalsma, 2014). These statistics highlight the critical need for identification and implementation of effective child and family interventions for the mental health service system. Case management is a widely offered service within the childrenâs mental health system, but there is a scarcity of literature and research on models of case management and their effec- tiveness. This chapter introduces one model of case management, Strengths Model for Youth, and summarizes the current evidence on its effectiveness
Practitionerâs Guidebook: Best Practices in Assessment for the Kansas Serious Emotional Disturbance Waiver
The Kansas Serious Emotional Disturbance (SED) Waiver Best Practices Guide for Assessment was developed to share best practices in assessment for Kansas children and families. Additionally, this guide was developed to support community mental health centers (CMHCs) in conducting accurate and equitable SED Waiver eligibility processes. CMHCs can supplement their initial staff CAFAS training and CAFAS booster training with this guide, as it accounts for specific challenges or concerns that are unique to Kansas and Kansasâ SED Waiver eligibility process.
The Guide is organized as follows:
âą Brief introduction to the CAFAS and PECFAS;
âą Developer identified CAFAS/PECFAS administration guidelines;
âą Summary of the common challenges observed regarding the CAFAS administration in Kansas and accompanying best practice recommendations; and
âą General best practices for conducting child and family assessments in mental health contexts.
This guide closes with an example case vignette and decision flow charts for some of the CAFAS domains
Quick Reference: Print-Friendly Best Practices and User Flowcharts for Kansas Serious Emotional Disturbance Waiver
Purpose: This Quick Reference Guide was developed to provide clinicians with easy-to-access recommendations and decision guides for common challenges in CAFAS/PECFAS assessment. The first section of the guide summarizes common challenges in overall CAFAS administration, and the second section reviews common challenges within each domain. Both sections include recommended assessment practices for addressing each challenge. The Guide concludes with quick reference decision flow charts for two CAFAS domains, which clinicians often find most challenging or confusing to complete, the Self-harmful Behavior domain and the Thinking domain
Magnetic properties of single-crystalline CeCuGa3
The magnetic behavior of single-crystalline CeCuGa3 has been investigated.
The compound forms in a tetragonal BaAl4-type structure consisting of
rare-earth planes separated by Cu-Ga layers. If the Cu-Ga site disorder is
reduced, CeCuGa3 adopts the related, likewise tetragonal BaNiSn3-type
structure, in which the Ce ion are surrounded by different Cu and Ga layers and
the inversion symmetry is lost. In the literature conflicting reports about the
magnetic order of CeCuGa3 have been published. Single crystals with the
centrosymmetric structure variant exhibit ferromagnetic order below approx. 4 K
with a strong planar anisotropy. The magnetic behavior above the transition
temperature can be well understood by the crystal-field splitting of the 4f
Hund's rule ground-state multiplet of the Ce ions
Theory of Umklapp-assisted recombination of bound excitons in Si:P
We present the calculations for the oscillator strength of the recombination
of excitons bound to phosphorous donors in silicon. We show that the direct
recombination of the bound exciton cannot account for the experimentally
measured oscillator strength of the no-phonon line. Instead, the recombination
process is assisted by an umklapp process of the donor electron state. We make
use of the empirical pseudopotential method to evaluate the Umklapp-assisted
recombination matrix element in second-order perturbation theory. Our result is
in excellent agreement with the experiment. We also present two methods to
improve the optical resolution of the optical detection of the spin state of a
single nucleus in silicon.Comment: 9 pages, 6 EPS figures, Revtex
Geoconservation, history of
[Excerto] The word "geoconservation" was probably used for the first time in Tasmania (Australia) in the beginning of the 1990s
(Sharples 1993). Sharples, a pioneer of Australian geoconservation, reports that during the period of 1993-1994, the
Forestry Commission of Tasmania prepared several reports with preliminary inventories of landforms in the state forests
of Tasmania in order to facilitate "the conservation of Earth systems ('Geoconservation')" (Sharples 1993). However,
initiatives to protect particular geological and geomorphological features started centuries before, during the seventeenth
century. The first example of the protection of geological features dates back to 1668, concerning the protection of the

Anomalously large oxygen-ordering contribution to the thermal expansion of untwinned YBa2Cu3O6.95 single crystals: a glass-like transition near room temperature
We present high-resolution capacitance dilatometry studies from 5 - 500 K of
untwinned YBa2Cu3Ox (Y123) single crystals for x ~ 6.95 and x = 7.0. Large
contributions to the thermal expansivities due to O-ordering are found for x ~
6.95, which disappear below a kinetic glass-like transition near room
temperature. The kinetics at this glass transition is governed by an energy
barrier of 0.98 +- 0.07 eV, in very good agreement with other O-ordering
studies. Using thermodynamic arguments, we show that O-ordering in the Y123
system is particularly sensitive to uniaxial pressure (stress) along the chain
axis and that the lack of well-ordered chains in Nd123 and La123 is most likely
a consequence of a chemical-pressure effect.Comment: 4 pages, 3 figures, submitted to PR
