As the on-going severe acute respiratory syndrome coronavirus 2 pandemic, we aimed to understand whether economic reopening (EROP) significantly influenced coronavirus disease 2019 (COVID-19) incidence. COVID-19 data from Texas Health and Human Services between March and August 2020 were analysed. COVID-19 incidence rate (cases per 100 000 population) was compared to statewide for selected urban and rural counties. We used joinpoint regression analysis to identify changes in trends of COVID-19 incidence and interrupted time-series analyses for potential impact of state EROP orders on COVID-19 incidence. We found that the incidence rate increased to 145.1% (95% CI 8.4–454.5%) through 4th April, decreased by 15.5% (95% CI −24.4 −5.9%) between 5th April and 30th May, increased by 93.1% (95% CI 60.9–131.8%) between 31st May and 11th July and decreased by 13.2% (95% CI −22.2 −3.2%) after 12 July 2020. The study demonstrates the EROP policies significantly impacted trends in COVID-19 incidence rates and accounted for increases of 129.9 and 164.6 cases per 100 000 populations for the 24- or 17-week model, respectively, along with other county and state reopening ordinances. The incidence rate decreased sharply after 12th July considering the emphasis on a facemask or covering requirement in business and social settings.
Emergency preparedness becomes more important with increased age, as older adults are at heightened risk for harm from disasters. In this study, predictors of preparedness actions and confidence in preparedness among older adults in the United States were assessed.
This nationally representative survey polled community-dwelling older adults ages 50-80 y (n = 2256) about emergency preparedness and confidence in addressing different types of emergencies. Logistic regression was used to identify predictors of reported emergency preparedness actions and confidence in addressing emergencies.
Participants’ mean age was 62.4 y (SD = 8); 52% were female, and 71% were non-Hispanic white. Living alone was associated with lower odds of having a 7-d supply of food and water (adjusted odds ratio [aOR] = 0.74; 95% confidence interval [CI]: 0.56-0.96), a stocked emergency kit (aOR = 0.64; 95% CI: 0.47-0.86), and having had conversations with family or friends about evacuation plans (aOR = 0.59; 95% CI: 0.44-0.78). Use of equipment requiring electricity was associated with less confidence in addressing a power outage lasting more than 24 h (aOR = 0.66; 95% CI: 0.47-0.94), as was use of mobility aids (OR = 0.65; 95% CI: 0.45-0.93).
These results point to the need for tailored interventions to support emergency preparedness for older adults, particularly among those who live alone and use medical equipment requiring electricity.
Multispectral imaging – the acquisition of spatially contiguous imaging data in a modest number (~3–16) of spectral bandpasses – has proven to be a powerful technique for augmenting panchromatic imaging observations on Mars focused on geologic and/or atmospheric context. Specifically, multispectral imaging using modern digital CCD photodetectors and narrowband filters in the 400–1100 nm wavelength region on the Mars Pathfinder, Mars Exploration Rover, Phoenix, and Mars Science Laboratory missions has provided new information on the composition and mineralogy of fine-grained regolith components (dust, soils, sand, spherules, coatings), rocky surface regions (cobbles, pebbles, boulders, outcrops, and fracture-filling veins), meteorites, and airborne dust and other aerosols. Here we review recent scientific results from Mars surface-based multispectral imaging investigations, including the ways that these observations have been used in concert with other kinds of measurements to enhance the overall scientific return from Mars surface missions.
How do planetary scientists analyze and interpret data from laboratory, telescopic, and spacecraft observations of planetary surfaces? What elements, minerals, and volatiles are found on the surfaces of our Solar System's planets, moons, asteroids, and comets? This comprehensive volume answers these topical questions by providing an overview of the theory and techniques of remote compositional analysis of planetary surfaces. Bringing together eminent researchers in Solar System exploration, it describes state-of-the-art results from spectroscopic, mineralogical, and geochemical techniques used to analyze the surfaces of planets, moons, and small bodies. The book introduces the methodology and theoretical background of each technique, and presents the latest advances in space exploration, telescopic and laboratory instrumentation, and major new work in theoretical studies. This engaging volume provides a comprehensive reference on planetary surface composition and mineralogy for advanced students, researchers, and professional scientists.
