An Examination of Crime Perception and Arkansas Fair Housing
This study examines the issue of fair housing from the standpoint of appraisal reports that determine the value of properties. Specifically, descriptors of crime within Arkansas appraisal reports are analyzed, along with completed interview questionnaires representing the mortgage lending, law enforcement, and home appraisal communities. This study provides pivotal findings with respect to appraisal reports in Arkansas and implications for public policy. Particularly, it finds that some of the most relevant stakeholders related to housing in Arkansas unfairly categorize certain geographic areas according to perceptions of crime, as indicated by a review of data found within appraisal reports. This study has implications for sales, rentals, and mortgage lending within the entire state of Arkansas; it also illustrates perpetuated stereotypes about specific groups of people. Finally, a significant policy recommendation is offered by this collaborative research
Policy Gaps and Opportunities: A Systematic Review of Autism Spectrum Disorder and Criminal Justice Intersections
LAY ABSTRACT: The number of people with autism spectrum disorder has increased, and as this population ages, research is showing high rates of contact with the criminal justice system among this group. Social and communication differences that autistic individuals experience can act as a risk factor during these interactions, as shown by public reports of negative and violent encounters between autistic individuals and the law enforcement. There is a clear need for evidence-based strategies to reduce high rates of contact and to improve outcomes when an interaction occurs. This article provides a systematic review of research on autism spectrum disorder and criminal justice system to compile this evidence base. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis structure was used to identify 89 articles after searching six databases. The Sequential Intercept Model describes the criminal justice system as different stages, or intercepts, that are connected, and the Sequential Intercept Model serves as an overall framework to organize the included articles. Articles were analyzed to identify research themes at each intercept, which offer guidance for policy and program changes that support equitable justice for autistic individuals

Ultra-Stable Environment Control for the NEID Spectrometer: Design and Performance Demonstration
Two key areas of emphasis in contemporary experimental exoplanet science are
the detailed characterization of transiting terrestrial planets, and the search
for Earth analog planets to be targeted by future imaging missions. Both of
these pursuits are dependent on an order-of-magnitude improvement in the
measurement of stellar radial velocities (RV), setting a requirement on
single-measurement instrumental uncertainty of order 10 cm/s. Achieving such
extraordinary precision on a high-resolution spectrometer requires
thermo-mechanically stabilizing the instrument to unprecedented levels. Here,
we describe the Environment Control System (ECS) of the NEID Spectrometer,
which will be commissioned on the 3.5 m WIYN Telescope at Kitt Peak National
Observatory in 2019, and has a performance specification of on-sky RV precision
< 50 cm/s. Because NEID's optical table and mounts are made from aluminum,
which has a high coefficient of thermal expansion, sub-milliKelvin temperature
control is especially critical. NEID inherits its ECS from that of the
Habitable-zone Planet Finder (HPF), but with modifications for improved
performance and operation near room temperature. Our full-system stability test
shows the NEID system exceeds the already impressive performance of HPF,
maintaining vacuum pressures below Torr and an RMS temperature
stability better than 0.4 mK over 30 days. Our ECS design is fully open-source;
the design of our temperature-controlled vacuum chamber has already been made
public, and here we release the electrical schematics for our custom
Temperature Monitoring and Control (TMC) system.Comment: Accepted for publication in JATI
Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial
Background
Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy
