Surveying Teachers' Preferences And Boundaries Regarding Human-Ai Control In Dynamic Pairing Of Students For Collaborative Learning, Kexin Bella Yang, Luettamae Lawrence, Vanessa Echeverría, Boyuan Guo, Nikol Rummel, Vincent Aleven

Instructional Technology and Learning Sciences Faculty Publications

Orchestration tools may support K-12 teachers in facilitating student learning, especially when designed to address classroom stakeholders’ needs. Our previous work revealed a need for human-AI shared control when dynamically pairing students for collaborative learning in the classroom, but offered limited guidance on the role each agent should take. In this study, we designed storyboards for scenarios where teachers, students and AI co-orchestrate dynamic pairing when using AI-based adaptive math software for individual and collaborative learning. We surveyed 54 math teachers on their co-orchestration preferences. We found that teachers would like to share control with the AI to lessen their …

Interpreting Covid-19 Deaths Among Nursing Home Residents In The Us: The Changing Role Of Facility Quality Over Time, Debasree Das Gupta, Uma Kelekar, Sidney C. Turner, Anupam A. Sule, Taya G. Jerman

Kinesiology and Health Science Faculty Publications

A report published last year by the Centers for Medicare & Medicaid Services (CMS) highlighted that COVID-19 case counts are more likely to be high in lower quality nursing homes than in higher quality ones. Since then, multiple studies have examined this association with a handful also exploring the role of facility quality in explaining resident deaths from the virus. Despite this wide interest, no previous study has investigated how the relation between quality and COVID-19 mortality among nursing home residents may have changed, if at all, over the progression of the pandemic. This understanding is indeed lacking given that …

Radiometric Calibration Of Skysats Using Near-Simultaneous Crossovers With Sentinel-2 Over Calibration Sites, Hannah Bourne, Arin Jumpasut, Alan Collison

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

Planet Labs currently operates a fleet of 21 high resolution Earth observation satellites known as SkySats. These sub-meter resolution satellites have high intra-day revisit rate capabilities, can image scenes in a range of viewing angles, create 3D scene composites and take videos even in regions traditionally difficult to observe due to low satellite capacity. The radiometric calibration of other satellite models within Planet’s fleet (Dove Classic, Dove R and SuperDove) is currently achieved using simultaneous crossovers with Sentinel-2. Radiometric calibration of SkySat imagery using Sentinel-2 poses unique challenges as it has relatively wide spectral bands and frequently takes images off-nadir. …

Characterizing Inter-Sensor Calibration Radiometric Biases Between Snpp And Noaa-20 Omps Nadir Profiler (Np) Sensor Data Records By Using Hybrid Methodologies, Banghua Yan, Chunhui Pan, Ding Liang, Jingfeng Huang, Junye Chen, Trevor Beck, Steven Buckner, Xin Jin, Xiaozhen Xiong

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

The Ozone Mapping & Profiler Suite (OMPS) Nadir Profiler (NP), onboard both the Suomi National Polar-orbiting Partnership (SNPP) satellite and the Joint Polar Satellite System NOAA-20 satellite, is an ultraviolet-visible imaging spectrometer that measures Earth’s albedo by registering terrestrial events to Earth image and extraterrestrial events to Solar spectral images. The NP operates from wavelengths of 250 to 310 nm to profile ozone observations in Earth’s stratosphere. Through years of intensive post-launch calibrations and validations, the Sensor Data Record (SDR) data from both SNPP and NOAA-20 NP sensors demonstrate good performance, meeting the SDR specifications (e.g., Pan et al., 2017). …

The Radiometric Scaling And Stability Assessment Of The Modis And Viirs Imagers To A Common Reference For The Next Edition Of Ceres Products, David Doelling, Conor Haney, Rajendra Bhatt, Benjamin Scarino, Arun Gopalan

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

The NASA CERES project has provided the climate quality observed TOA and computed surface fluxes to the scientific community. CERES uses MODIS and VIIRS imagers to retrieve cloud properties needed to convert Terra, Aqua, NPP, and NOAA-20 CERES footprint radiance observations into fluxes. The imagers are also used to radiometrically scale the geostationary sensors (GEO) radiances to the imager calibration reference to ensure that the GEO derived cloud properties and broadband TOA fluxes are consistent in both space and time. Both the imager and GEO retrieved cloud properties are used to compute the surface fluxes. The CERES imager and GEO …

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

The Sentinel-2 mission observes the Earth in 13 spectral bands in the visible and SWIR with a repeat cycle of 5 days for each satellite unit A and B. A complete reprocessing of the Sentinel-2 archive to generate the "Collection-1" is currently under preparation. In this presentation we describe the activities performed by the Sentinel-2 Mission Performance Center to prepare the calibration baseline for Collection-1. The preparation activities involve a correction of some minor errors in the definition of the spectral response function at the beginning of the mission. A more significant change concerns the possible harmonization between the two …

Nonuniform Calibration Artifacts In Oco-2 & Oco-3, Robert Rosenberg, Lars Chapsky, David Crisp, Jonathan Hobbs, Graziela Keller, Richard Lee, Yuliya Marchetti, Gary Spiers, Annmarie Eldering, Stephen Maxwell

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

The Orbiting Carbon Observatory -2 and -3 instruments have been measuring reflected sunlight in the near infrared from low Earth orbit since 2014 and 2019 respectively. A three-channel spectrometer with common entrance optics measures narrow spectral bands centered at 765 nm for oxygen and 1608 and 2065 nm for carbon dioxide. To achieve spectral resolving power exceeding 18000:1, a diffraction grating disperses each spectrum over 1016 columns of the focal plane array. In the spatial dimension, 160 central rows are averaged into eight footprints. For accurate and precise retrievals of carbon dioxide concentration, the calibration process needs to correct for …

Reflective Engineered Diffusers For The Roman Space Telescope Simplified Relative Calibration System, Eric Frater, Benjamin Cromey, Timothy Finch, Ray Wright, Thomas Delker

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

The Wide Field Instrument (WFI) on NASA’s Roman Space Telescope (RST) has an on-board calibrator called the simplified Relative Calibration System (sRCS). The sRCS is designed to project flat-field calibration light onto the WFI focal plane in two modes of operation. One mode illuminates a quasi-Lambertian diffuser that blocks the full aperture of the telescope, and the other mode uses a small reflective engineered diffuser that sits behind each filter’s aperture mask in the WFI element wheel assembly (EWA). The second mode, called “Lamp On Lamp Off” (LOLO), uses these metallic-coated engineered diffusers to illuminate the focal plane concurrently with …

Measurements Of Absolute, Si Traceable Lunar Irradiance With The Airborne Lunar Spectral Irradiance (Air Lusi) Instrument, John T. Woodward, Steven W. Brown, Steve Grantham, Thomas C. Larason, Stephen E. Maxwell, Kevin Turpie, S. Andrew Gadsden, Andrew Newton, Thomas C. Stone

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

The Moon is a very useful calibration target for Earth-observing sensors in orbit because its surface is radiometrically stable and it has a radiant flux comparable to Earth scenes. To predict the lunar irradiance given an illumination and viewing geometry, the United States Geological Survey (USGS) has developed the Robotic Lunar Observatory (ROLO) Model of exo-atmospheric lunar spectral irradiance. The USGS ROLO model represents the current most precise knowledge of lunar spectral irradiance and is used frequently as a relative calibration standard by space-borne Earth-observing sensors. However, its accuracy as an absolute reference may be limited to several percent and …

Evaluation Of Air-Lusi Measurements To Advance Lunar Modeling And The Rolo Lunar Calibration Reference, Thomas C. Stone, Kevin Turpie, Steven Brown, Stephen Maxwell, John Woodward

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

The airborne Lunar Spectral Irradiance (air-LUSI) project is dedicated to acquiring high-accuracy, spectrally resolved measurements of the Moon from the NASA ER-2 high-altitude aircraft, flying above more than 90% of Earth's atmosphere. The air-LUSI instrument is a non-imaging system designed specifically for measuring spectral irradiance of the Moon at wavelengths from ~350 nm to 1100 nm. The project aims to achieve absolute measurement uncertainty approaching 0.5% (k=1) with traceability to NIST radiometric standards and SI. These measurements can advance lunar calibration by constraining absolute scale of models that constitute the lunar radiometric reference, such as the USGS ROLO model.

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

Work on the Spacecraft and Earth-based Lunar Irradiance Model (SLIM) system has concentrated on the SLIMED model (pronounced as if you lost weight), which uses a weighted least-squares fit to many instrument data sets and is continuous in all dimensions. Total Solar Irradiance (TSI) and Solar Spectral Irradiance (SSI) variations are now included. A libration correction to the observations based on integration of reflectance maps made by Lunar orbiters can be included. Current fits involve 2 observatory sets (ROLO and NIST:Cramer) and 8 LEO instruments (SeaWiFS, L8-OLI, Hyperion, Terra and Aqua MODIS, SNPP-VIIRS, PLEIADES A and B) for a total …

Characterization For Ir And Microwave Instruments With Solar System Objects, Martin Burgdorf, S. A. Buehler, V. John

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

Serendipitous observations of our Moon or planets of the inner solar system provide a unique means to the characterization of the (quasi-)optical properties of instruments on meteorological research satellites in flight, because their diameters are much smaller than the size of a pixel or the field of view. We investigated how beamwidth, channel co-registration, and pointing accuracy can be determined with such observations. For this we identified and analysed intrusions of the Moon in the deep space views of AMSU-B (Advanced Microwave Sounding Unit - B) and MHS (Microwave Humidity Sounder) on various satellites in polar orbits and as well …

Current Challenges In The Remote Sounding Of The Earth, Chris Barnet

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

This workshop will focus on the topic of remote sounding of the Earth’s atmosphere using modern space-borne hyperspectral infrared (e.g., AIRS, IASI, CrIS) and microwave (e.g., AMSU, MHS, ATMS) instruments to extract information about the Earth’s atmosphere. This workshop will have three major sections. The first section will be a conceptual introduction to the mathematical methods of sounding, that is, radiative transfer and inversion (a.k.a. retrieval) of observations. The 2^nd section will highlight the NOAA-Unique Combined Atmospheric Processing System (NUCAPS) and the Community Long-term Infrared Microwave Coupled Atmospheric Product System (CLIMCAPS) to illustrate the value and limitations of modern …

Strengthening Sisters: How Latter-Day Saint Missionary Service Prepares Women For Leadership, Sara Mcphee Lafkas, Wendy Fox-Kirk, Susan R. Madsen, Robbyn T. Scribner

Marketing and Strategy Faculty Publications

Women, especially those from highly religious societies, are underrepresented in professional and civic leadership positions. Considering how women's life experiences, especially from religious volunteer opportunities, can be reframed as training for broader leadership roles could help address this disparity. The potential for women to learn leadership skills from volunteer religious service is an overlooked, but possibly important, means of transferability to larger leadership roles. The current article describes a qualitative study of women's perceptions of leadership skills gained while serving as full-time volunteer missionaries for The Church of Jesus Christ of Latter-day Saints during young adulthood. Respondents described perceptions of …

Wild Boar In Flanders, Belgium: (Dis)Agreements Between Key Stakeholders On Wild Boar Management Objectives, Actions, And Legal Provisions, Caroline Geeraerts, Anneleen Rutten, Emma Cartuyvels, Pieter Verschelde, Sander Devisscher, Francis Turkelboom, Paul Quataert, Jim Casaer

Human–Wildlife Interactions

Wild boar (Sus scrofa) reappeared in Flanders, Belgium in 2006 after more than half a century of absence. Besides being a native and highly valued game species in Europe, wild boar are also known to be responsible for car collisions, crop damage, disease transmission, and ecological damage at high densities. The management of wild boar therefore seeks to balance these positive and negative impacts. Given the highly fragmented landscape in Flanders and its multifunctional use, coexistence with wild boar is only possible through integrated management involving relevant stakeholder groups. However, to be successful, this requires that the management …

Adapting To Sea Level Rise: Insights From A New Evaluation Framework Of Physical Design Projects, Daniella Hirschfeld, Kristina E. Hill, Ellen Plane

Landscape Architecture and Environmental Planning Faculty Publications

Designers and engineers are developing proposals for physical projects to adapt coastal sites to future sea level rise related threats. This puts pressure on local and regional decision makers to develop strategic frameworks for prioritizing, permitting and funding such projects. However, no systematic evaluation tools exist for the full range of these innovative designs. We build on the literature to develop an evaluation framework that synthesizes two different approaches to categorize these proposals and provide insight for coastal managers and decision makers. We apply this framework to physical projects that address sea level rise in their design around the San …

Contributors To Reduced Life Expectancy Among Native Americans In The Four Corners States, Olusola A. Omisakin, Hyojun Park, Max T. Roberts, Eric N. Reither

Sociology, Social Work and Anthropology Student Research

To assess trends in life expectancy and the contribution of specific causes of death to Native American-White longevity gaps in the Four Corners states, we used death records from the National Center for Health Statistics and population estimates from the U.S. Census Bureau from 1999–2017 to generate period life tables and decompose racial gaps in life expectancy. Native American-White life expectancy gaps narrowed between 2001 and 2012 but widened thereafter, reaching 4.92 years among males and 2.06 years among females in 2015. The life expectancy disadvantage among Native American males was primarily attributable to motor vehicle accidents (0.96 years), liver …

Association Between Financial Education, Affective And Cognitive Financial Knowledge, And Financial Behaviors, Lucy M. Delgadillo, Yoon Lee

Applied Sciences, Technology and Education Faculty Publications

Using data from the 2018 National Financial Capability Study, this paper examined the relationship between financial education participation and affective and cognitive financial knowledge. Involvement in financial education yielded statistically significant associations between affective and cognitive domains. The results showed that participation in financial education was associated with both cognitive and affective financial knowledge as well as long-term financial behaviors. The findings supported the case for life-long learning of financial education for young adults, Blacks and Hispanics, and women. One important implication was the need to include both the affective and cognitive domains when teaching or researching financial education.

Human–Wildlife Interactions

Wild pigs (Sus scrofa) are a non-native, invasive species that cause considerable damage and transmit a variety of diseases to livestock, people, and wildlife. We explored Twitter, the most popular social media micro-blogging platform, to demonstrate how social media data can be leveraged to investigate social identity and sentiment toward wild pigs. In doing so, we employed a sophisticated machine learning approach to investigate: (1) the overall sentiment associated with the dataset, (2) online identities via user profile descriptions, and (3) the extent to which sentiment varied by online identity. Results indicated that the largest groups of online …

The Disksat: A Two-Dimensional Containerized Satellite, Richard P. Welle, Catherine C. Venturini, David A. Hinkley, Joseph W. Gangestad

Small Satellite Conference

A key factor in the remarkable expansion of the CubeSat class of spacecraft over the past two decades is launch containerization. The container protects the launch vehicle and primary payload from issues that might arise from the CubeSat (which is essential for rideshare), and the standardized and highly-simplified launch interface reduces integration cost for the launch provider and development cost for the CubeSat builder. The downside of containerization is that the size of the contained satellites is rigidly limited. While there are available designs for larger dispensers and CubeSats, very few CubeSats larger than 6U have flown, and none have …

Optical Time-Transfer For Bistatic Sar Small Spacecraft, Danielle E. Coogan, John W. Conklin, Nicholas Belsten, Kerri Cahoy, Adam Zufall, Anh Nguyen, Shadi Oveisgharan, Batuhan Osmanoglu

Small Satellite Conference

A spacecraft-to-spacecraft optical time-transfer simulation has been developed as a tool for informing NASA’s Surface Deformation and Change (SDC) mission architecture. The SDC mission will combine radar images from multiple spacecraft to improve understanding of the Earth’s sea-level and landscape changes. Spacecraft must be precisely synchronized in order to create sharp and phase accurate radar images. Simulation of multiple spacecraft time-synchronizing via laser communication can inform technology choices of a mission by providing sub-nanosecond precision estimates of clock error. This timing and ranging simulation has been combined with a radar system performance analysis pipeline. The simulated timing errors are used …
