Iris Print Attack Detection using Eye Movement Signals
(2022-06) Raju, Mehedi Hasan; Lohr, Dillon J.; Komogortsev, Oleg V.
Iris-based biometric authentication is a wide-spread biometric modality due to its accuracy, among other benefits. Improving the resistance of iris biometrics to spoofing attacks is an important research topic. Eye tracking and iris recognition devices have similar hardware that consists of a source of infrared light and an image sensor. This similarity potentially enables eye-tracking algorithms to run on iris-driven biometrics systems. The present work advances the state-of-the-art of detecting iris print attacks, wherein an imposter presents a printout of an authentic user’s iris to a biometrics system. The detection of iris print attacks is accomplished via analysis of the captured eye movement signal with a deep learning model. Results indicate better performance of the selected approach than the previous state-of-the-art.
Food Insecurity Associated with Higher Stress, Depressive Symptoms, and Lower Diet Quality among Women Caregivers in North Carolina
(Multidisciplinary Digital Publishing Institute (MDPI), 2024-07) Butler, Lauren; Johnson, Cassandra M.; Hardison-Moody, Annie; Bowen, Sarah K.
Background: Research suggests a bidirectional relationship between food insecurity and stress, but few studies have examined associations of food insecurity with stress and other indicators of cardiometabolic health, including depression, diet quality, and body weight, among lower-income women in the U.S. Methods: This cross-sectional study analyzed data from lower-income women caregivers living in North Carolina (n = 100): 42% Black/African American, 25% Hispanic/Latina, and 33% White women. Multivariable linear regression models were used to determine associations of food insecurity status with perceived stress, depressive symptoms, diet quality, and body mass index (BMI). Multivariable logistic regression models were used to determine associations of food insecurity with clinical depression and BMI ≥ 30 kg/m2. Associations were examined with and without adjustment for perceived stress. Results: Forty-two percent of the sample were experiencing food insecurity. Compared to food secure caregivers, food-insecure caregivers had significantly higher perceived stress (β: +7.51; 95%CI: 4.19, 10.84) and depressive symptoms (β: +3.55; 95%CI: 0.54, 6.56) and lower diet quality (β: −9.10; 95%CI: −15.81, −2.40). Associations with BMI outcomes were not statistically significant. Conclusion: Findings support removing stigma in nutrition assistance programs and clinical interactions, motivate future longitudinal studies, and inform the development of destigmatizing interventions for health promotion or disease prevention.
Food Delivery Apps and their Potential to Address Food Insecurity in Older Adults: A Review
(Multidisciplinary Digital Publishing Institute (MDPI), 2024-09) Hwang, Sangchul; Johnson, Cassandra M.; Charles, Joni; Biediger-Friedman, Lesli
The proportion of older adults is increasing globally, yet many of them experience food insecurity. Technological innovations, such as increased access to internet- and mobile-based food delivery apps (FDAs), may help mitigate food insecurity. However, this topic has been understudied. This scoping review searched for publications and online technical reports from around the world using interdisciplinary databases like ScienceDirect and internet sources like government websites, respectively. Eligible references were published recently (2019–present) and focused on general technology use, including apps, among older adults (≥50 years) or FDAs for food insecurity or nutritional health generally or specifically among older adults. The search identified 19 studies from 10 countries and extracted relevant information for summary tables. A limited number of studies supported the idea that FDAs can help address food insecurity, but there are important equity considerations for older adults living in rural areas or with constrained physical abilities. Consistently, customized app features and functions increased the intention to use FDAs. In addition, FDAs may have health and environmental impacts, such as food waste and increased access or promotion of ultraprocessed foods. Additional research is needed to elucidate the potential of FDAs to address food insecurity generally and specifically among older adults.
Building Bobcat Bounty: The Design, Implementation, and Initial Evaluation of a Student-Led Food Pantry to Address College Student Food Insecurity
(Multidisciplinary Digital Publishing Institute (MDPI), 2024-09) Biediger-Friedman, Lesli; Johnson, Cassandra M.; Thornton, Hannah; Buckley, Marissa
Background: Campus food pantries can address food insecurity among college students, but little is known about how to create a model at a Hispanic-Serving Institution (HSI). This study evaluated a food pantry, which was part of a learning community for dietetics and nutrition students at an HSI. Methods: The Bobcat Bounty food pantry was created and evaluated using a mixed-methods approach, including food inventories before and after each pantry, observations of operations (written by volunteers at each pantry, n = 27), new client intake (n = 947) and client satisfaction surveys (n = 267)), and stakeholder interviews (n = 16 after the first year of implementation). Descriptive statistics and t-tests were used for quantitative analyses, and qualitative analyses included interview transcript coding and peer debriefing. Results: Here, 2 faculty members and a team of 19 students/dietetic interns operated the weekly campus food pantry, which served 3567 students and distributed 33,000 pounds of food. Client satisfaction surveys provided evidence for addressing food insecurity for college students. Volunteers and stakeholders generated insights for operational evolution and sustainability of the food pantry. Conclusions: Results highlighted key factors for initial efficacy and strategies for long-term success. Findings may be incorporated by dietetic education and training programs to provide research-focused and culturally relevant experiential learning.
