How Do People With Disabilities Cope While Waiting for Disability Insurance Benefits?
Disability Insurance waiting time varies from a few months to several years. We estimate the causal effect of longer waiting times on the use of five financial coping strategies. We find that SNAP benefits are the most responsive to longer waiting times. Moreover, while spousal employment is not responsive to longer wait times, spousal employment leads to longer waiting times, presumably because these applicants are more able to appeal. Together, these results suggest that coping strategies are used to both help applicants during the wait time and to extend the waiting time and increase their probability of success
The Main Belt Comets and ice in the Solar System
We review the evidence for buried ice in the asteroid belt; specifically the questions around the so-called Main Belt Comets (MBCs). We summarise the evidence for water throughout the Solar System, and describe the various methods for detecting it, including remote sensing from ultraviolet to radio wavelengths. We review progress in the first decade of study of MBCs, including observations, modelling of ice survival, and discussion on their origins. We then look at which methods will likely be most effective for further progress, including the key challenge of direct detection of (escaping) water in these bodies
A broadband thermal emission spectrum of the ultra-hot Jupiter WASP-18b
Close-in giant exoplanets with temperatures greater than 2,000 K (''ultra-hot
Jupiters'') have been the subject of extensive efforts to determine their
atmospheric properties using thermal emission measurements from the Hubble and
Spitzer Space Telescopes. However, previous studies have yielded inconsistent
results because the small sizes of the spectral features and the limited
information content of the data resulted in high sensitivity to the varying
assumptions made in the treatment of instrument systematics and the atmospheric
retrieval analysis. Here we present a dayside thermal emission spectrum of the
ultra-hot Jupiter WASP-18b obtained with the NIRISS instrument on JWST. The
data span 0.85 to 2.85 m in wavelength at an average resolving power of
400 and exhibit minimal systematics. The spectrum shows three water emission
features (at 6 confidence) and evidence for optical opacity,
possibly due to H, TiO, and VO (combined significance of 3.8).
Models that fit the data require a thermal inversion, molecular dissociation as
predicted by chemical equilibrium, a solar heavy element abundance
(''metallicity'', M/H = 1.03 solar), and a
carbon-to-oxygen (C/O) ratio less than unity. The data also yield a dayside
brightness temperature map, which shows a peak in temperature near the
sub-stellar point that decreases steeply and symmetrically with longitude
toward the terminators.Comment: JWST ERS bright star observations. Uploaded to inform JWST Cycle 2

Integration of a vaccine checklist to promote discussion between patients and providers and to increase rate of vaccination
A vaccine checklist created by Center for Disease Control (CDC) was utilized as a tool to increase rate of vaccination in the George Washington Medical Faculty Associates medicine clinic from July 2018 to July 2019. This quality improvement project applied Plan-Do-Study-Act (PDSA) framework to iteratively integrate the checklist into clinical practice. A questionnaire, which used to assess resident\u27s vaccination practice and knowledge, showed that patients rarely initiate discussion regarding vaccination and only few medical residents remember the complex vaccine schedule. Different ways of distributing the vaccine checklist were explored; ultimately, the checklists, along with the patient intake forms, were given to the patients by the medical assistants. The integration of the vaccine checklist went smoothly with minimal interruption to workflow and 75% of the checklists were filled out by the patients. The vaccine checklist was mostly well received by the patients; it was considered educational and not overwhelming. In the last PDSA cycle, 1 patient out of 8 initiated discussion regarding vaccination with their providers during a focus visit. Incorporating the vaccine checklist with the patient intake form during every visit may act as a catalyst in increasing number of times discussion occurs. Given the complex vaccine schedule, the checklist can also be used an additional resource to help remind providers the appropriate vaccines recommendations. Future projects can incorporate the vaccine checklist into patient intake form and measure number of vaccination administered after utilization of the checklist to assess change in rate of vaccination
