Status of the ILC Main Linac BPM R&D
An introduction and the status of R&D activities for a high-resolution,
"cold" beam position monitor (BPM) and the related read-out electronics are
discussed. Two different BPM detector concepts, to be attached to the SC
quadrupole and located inside the ILC cryomodule, are currently under
investigation: A resonant dipole-mode cavity-style BPM pickup, developed at
Fermilab, and a re-entrant resonant coaxial waveguide BPM, designed by
CEA-Saclay. While the 1.5 GHz dipole-mode cavity BPM is still in the R&D phase,
the re-entrant BPM has already passed first beam tests, including its read-out
system. Furthermore, the LAPP group is developing radiation tolerant digital
read-out systems, which are tested at the CLIC test facility (CTF).Comment: LCWS / ILC08 conference contribution, 6 pages, 6 figure
Marauders, Mud, and Money: The Misapplication, Development, and Exploitation of Logistics During the Second Seminole War, 1835-1839
The Second Seminole War, fought from 1835-1842, was undoubtedly the longest, costliest conflict the United States engaged in between the American Revolution and the Civil War. From 1836 to 1839 the federal budget quadrupled appropriations of the conflict. As the war escalated in scale, many of these funds went to paying civilian claims and the supplying of Volunteer regiments with horses and gear for their short campaign contracts. This study will argue that the formation, development, and eventual exploitation of the logistical supply lines have been a critically overlooked aspect of the Second Seminole War. Using seldom-analyzed records of the Quartermaster Department, new trends emerge in the typical narratives of the war, particularly surrounding the federal government's purchase, sale, use, and abuse of horses both in and outside of the theater of war. The misapplication of horses negatively affected the operational, logistical, and financial integrity of American forces during the first campaigns of the Second Seminole War
Review of terminology and recent research related to handwriting problems
In seeking an explanation or solution to dysgraphia, one finds that recent literature in the various professional periodicals makes no mention of dysgraphia. The question arises, is dysgraphia a forgotten disability, or has the disability found a new label? The first purpose of this paper is to make clear the meaning of the term dysgraphia. The second purpose of this paper is to review what recent research has been done and solutions to the various types of handwriting problems
High Resolution BPM Upgrade for the ATF Damping Ring at KEK
A beam position monitor (BPM) upgrade at the KEK Accelerator Test Facility
(ATF) damping ring has been accomplished, carried out by a KEK/FNAL/SLAC
collaboration under the umbrella of the global ILC R&D effort. The upgrade
consists of a high resolution, high reproducibility read-out system, based on
analog and processing, and also implements a new automatic gain error
correction schema. The technical concept and realization as well as results of
beam studies are presented.Comment: 3 pp. 10th European Workshop on Beam Diagnostics and Instrumentation

Mixed-Methods Exploration of Group Therapy for Substance Use Disorders: Prospects for Evidence-Based Practice.
Evidence-based treatments (EBTs) for substance use disorders (SUDs) often are not utilized in clinical practice or lag years behind in their uptake. One underappreciated dimension of this research-practice gap is a mismatch in treatment modality: Whereas research efforts have focused on individual therapy, the majority of SUD treatment is in group format. In this mixed-methods three-study dissertation, I aim to narrow this gap by exploring how SUD clinicians facilitate group therapy. First, I conducted a national online survey with 566 SUD group therapy clinicians about their most commonly utilized group practices. Survey results confirm that group therapy is the most widely used SUD treatment modality, with especially high prevalence of open groups; clinicians also reported high utilization of EBT components (especially motivational interviewing and cognitive behavioral therapy) but with varying use of 35 specific practices and moderate use of questionable/less-effective practices. For the remaining two studies, I conducted qualitative thematic content analyses of semi-structured interviews with 13 clinicians at three outpatient SUD specialty clinics in the Midwestern U.S. The first qualitative analysis, which also included interviews with clinical directors, focused on organizational factors that facilitate and impede EBT implementation. Results indicate considerable challenges for integrating EBTs within each clinic, in terms of complexities with clinics’ provision of group therapy, exclusive use of open groups, use of treatment structures (e.g., group duration and session length) that are not readily compatible with existing EBTs, and use of a suite of treatments rather than standalone interventions; considerable adaptations are thus necessary to utilize existing EBTs. For the second qualitative analysis, I present complexities and barriers for group therapy facilitation, including use of EBTs, among individual clinicians. Results indicate that clinicians emphasized the importance of providing individualized and engaging treatment, necessitating considerable flexibility for group facilitation; however, clinicians also had serious challenges in this regard, due to complex group dynamics and organizational deficits and barriers (limited group therapy experience, limited quality control efforts, the predominance of psychoeducation, and limited attention to clients’ demographic diversity). For each study, I discuss recommended strategies for researchers and clinicians toward improved innovation and implementation of evidence-based practice.PhDPsychologyUniversity of Michigan, Horace H.

A new species of Daldinia (Xylariaceae) from the Argentine subtropical montane forest
Based on a combination of morphological, molecular phylogenetic and chemotaxonomic evidence, a new species of Daldinia from Northwest of Argentina is described. Daldinia korfii is morphologically related to D. placentiformis, but differs in having brown vinaceous, KOH-extractable pigments and the tissue below the perithecial layer is composed of inconspicuous to conspicuous alternating zones in the new taxon.Fil: Sir, Esteban Benjamin.

Preliminary calibration of a generic scramjet combustor
The results of a preliminary investigation of the combustion of hydrogen fuel at hypersonic flow conditions are provided. The tests were performed in a generic, constant-area combustor model with test gas supplied by a free-piston-driven reflected-shock tunnel. Static pressure measurements along the combustor wall indicated that burning did occur for combustor inlet conditions of P(static) approximately equal to 19kPa, T(static) approximately equal to 1080 K, and U approximately equal to 3630 m/s with a fuel equivalence ratio approximately equal to 0.9. These inlet conditions were obtained by operating the tunnel with stagnation enthalpy approximately equal to 8.1 MJ/kg, stagnation pressure approximately equal to 52 MPa, and a contoured nozzle with a nominal exit Mach number of 5.5
