Analyzing Stops, Citations, and Searches in Washington and Beyond

Racial disproportionality in the criminal justice system is a fact. But the fact of racial disproportionality is the beginning and not the end of the conversation. The fact that blacks are overrepresented in stop, arrest, charge, pretrial detention, conviction, and incarceration statistics demonstrates only correlation and not causation. A number of commentators caution that disproportionality and the overrepresentation of blacks, Native-Americans, and Hispanics in Washington State’s prisons do not prove racial discrimination. Further, the fact of disproportionality at each stage of criminal justice processing does not prove that racial discrimination occurs at each particular stage. For example, the observed disproportionality at imprisonment might merely be a downstream artifact of disproportionality at conviction, which might in turn be a downstream artifact of pretrial detention, charge, arrest, or stop. Closer analysis of each stage is required in order to determine whether observed disproportionality is a product of legally relevant factors as opposed to suggesting more strongly that race plays an illegitimate role. This article seeks to examine more closely the disproportionality with regard to traffic stops, citations, and searches. We focus on three reports produced by a team of researchers from Washington State University (WSU) that examine Washington State Patrol traffic stops, citations, and searches

SeaWiFS technical report series. Volume 10: Modeling of the SeaWiFS solar and lunar observations

Post-launch stability monitoring of the Sea-viewing Wide Field-of-view Sensor (SeaWifs) will include periodic sweeps of both an onboard solar diffuser plate and the moon. The diffuser views will provide short-term checks and the lunar views will monitor long-term trends in the instrument's radiometric stability. Models of the expected sensor response to these observations were created on the SeaWiFS computer at the National Aeronautics and Space Administration's (NASA) Goddard Space Flight Center (GSFC) using the Interactive Data Language (IDL) utility with a graphical user interface (GUI). The solar model uses the area of intersecting circles to simulate the ramping of sensor response while viewing the diffuser. This model is compared with preflight laboratory scans of the solar diffuser. The lunar model reads a high-resolution lunar image as input. The observations of the moon are simulated with a bright target recovery algorithm that includes ramping and ringing functions. Tests using the lunar model indicate that the integrated radiance of the entire lunar surface provides a more stable quantity than the mean of radiances from centralized pixels. The lunar model is compared to ground-based scans by the SeaWiFS instrument of a full moon in December 1992. Quality assurance and trend analyses routines for calibration and for telemetry data are also discussed

Mechanical Properties of Small Clear Specimens and Visually Graded Lumber from Living and Spruce Budworm-Killed Balsam Fir

Small clear specimens from living balsam fir and from spruce budworm-killed balsam fir dead 3 months, 12 months, and 22 months were tested in bending and compression perpendicular to the grain. Results indicated that modulus of rupture (MOR) of specimens from budworm-killed trees dead 3 months or more was significantly lower than MOR of specimens from living trees. Modulus of elasticity (MOE) appeared to be less sensitive to changes in budworm-killed material than MOR. Stress at the proportional limit for compression perpendicular to the grain was significantly lower for specimens from trees dead 22 months than for specimens from living trees. Both MOE and MOR in bending were determined for visually graded nominal 2- by 4-inch lumber from living and spruce budworm-killed balsam fir dead 12 months and 22 months. Average MOE values for living balsam fir were 1.274 x 106 psi, 1.217 x 106 psi, and 1.175 x 106 psi for Construction, Standard and Utility grades, respectively. Average MOR values for the same grades of living material were 4,699 psi, 4,684 psi, and 4,352 psi, respectively. Average MOE and MOR for Utility grade lumber from both spruce budworm-killed categories were not significantly different from the average MOE and MOR for living balsam fir. Statistical analyses of the MOE and MOR data for Construction and Standard grades of budworm-killed lumber were not performed due to the small sample sizes

Thermally Activated Magnetization and Resistance Decay during Near Ambient Temperature Aging of Co Nanoflakes in a Confining Semi-metallic Environment

We report the observation of magnetic and resistive aging in a self assembled nanoparticle system produced in a multilayer Co/Sb sandwich. The aging decays are characterized by an initial slow decay followed by a more rapid decay in both the magnetization and resistance. The decays are large accounting for almost 70% of the magnetization and almost 40% of the resistance for samples deposited at 35 $^oC$. For samples deposited at 50 $^oC$ the magnetization decay accounts for $\sim 50$ of the magnetization and 50% of the resistance. During the more rapid part of the decay, the concavity of the slope of the decay changes sign and this inflection point can be used to provide a characteristic time. The characteristic time is strongly and systematically temperature dependent, ranging from $\sim1$x$10^2 s$ at 400K to $\sim3$x$10^5 s$ at 320K in samples deposited at $35 ^oC$. Samples deposited at 50 $^oC$ displayed a 7-8 fold increase in the characteristic time (compared to the $35 ^oC$ samples) for a given aging temperature, indicating that this timescale may be tunable. Both the temperature scale and time scales are in potentially useful regimes. Pre-Aging, Scanning Tunneling Microscopy (STM) reveals that the Co forms in nanoscale flakes. During aging the nanoflakes melt and migrate into each other in an anisotropic fashion forming elongated Co nanowires. This aging behavior occurs within a confined environment of the enveloping Sb layers. The relationship between the characteristic time and aging temperature fits an Arrhenius law indicating activated dynamics

Comments on the Preliminary Framework for Equitable Allocation of COVID-19 Vaccine

On September 1, 2020 the National Academies released a draft framework for Equitable Allocation of a COVID-19 Vaccine. In this response, we analyze the proposed framework and highlight several areas. Among the proposed changes, we highlight the need for the following interventions. The final framework for distribution of COVID-19 vaccines should give a higher priority to populations made most vulnerable by the social determinants of health. It should incorporate more geography-based approaches in at least some of the four proposed phases of vaccine distribution. It should address the possibility of a vaccine being made available through an emergency use authorization (EUA), which we argue should not serve as a basis for widespread distribution of COVID-19 vaccines, and which may not be appropriate at all for the regulatory review of new vaccines. Moreover, it should address potential adjustments to the allocative framework once additional data pertaining to multiple vaccines becomes available, especially by discussing whether steps should be taken to prevent the administration of different vaccines to the same individual. Finally, it should provide guidance on allocation of vaccine in the case of a surplus, and specifically the Committee should specify whether unused doses of vaccine would automatically be allocated to next-level priority populations, and whether that would take place in the same geographical area

Comprehensive geriatric assessment in perioperative care: a protocol for a systematic review and qualitative synthesis

INTRODUCTION: Comprehensive geriatric assessment (CGA) is an intervention that has been deployed in the perioperative setting with the aim to improve outcomes for older patients admitted to hospital. Older patients undergoing surgery are more likely to have postoperative complications, a longer hospital stay and be discharged to a care facility. Despite the increasing application of this intervention within surgical services, the evidence for CGA remains limited in this group. The aim of this systematic review is to describe CGA as in intervention applied to surgical populations in randomised controlled trials (RCTs) as well as the outcomes assessed. METHODS AND ANALYSIS: A systematic search of RCTs of CGA in surgery will be run in Embase, Medline, CINAHL (Cumulative Index to Nursing and Allied Health Literature) and Cochrane library. Further articles will be identified from reference lists in relevant studies found in the search. A narrative synthesis will be undertaken outlining specialties included, detailed descriptions of the intervention and outcomes. ETHICS AND DISSEMINATION: No ethical approval is required. The results of this review will be published and used as the basis of work to optimise this intervention for future trials in surgical populations. PROSPERO REGISTRATION NUMBER: This review is registered with PROSPERO CRD42020221797

Optimizing H1 cavities for the generation of entangled photon pairs

We report on the theoretical investigation of photonic crystal cavities etched on a suspended membrane for the generation of polarization entangled photon pairs using the biexciton cascade in a single quantum dot. The implementation of spontaneous emission enhancement effect increases the entanglement visibility, while the concomitant preferential funneling of the emission in the cavity mode increases the collection of both entangled photons. We demonstrate and quantify that standard cavity designs present a polarization dependent emission diagram, detrimental to entanglement. The optimization of H1 cavities allows to obtain both high collection efficiencies and polarization independent emission, while keeping high Purcell factors necessary for high quality entangled photon sources
