A Trigger For The Autonomous Decommissioning Of Smart Devices, Ravindra Mangar, Jared Chandler, Jingyu Qian, Carl A. Gunter, Timothy J. Pierson, David Kotz

Dartmouth Scholarship

Smart devices are ubiquitous in modern environments, yet their decommissioning phase remains poorly studied and often overlooked in system design. We define secure decommissioning as the process by which a smart device securely disconnects from its environment and makes sensitive data inaccessible. If not decommissioned, devices may retain sensitive information – such as security credentials or user-behavior data that could be recovered by an adversary. Unfortunately, some users may forget to decommission a device when they dispose or sell it, and cannot decommission a device that is lost or stolen. This paper investigates a trigger mechanism for individual wireless smart …

More Than Just A Criminal: Talking Back As A Critical Autoethnographic Journey, Anakin Rivera Ramirez

Psychology Faculty Publications and Presentations

This article explores the experiences of doctoral students with criminal records navigating higher education, using a critical theoretical framework to highlight the unique challenges and triumphs I faced. Drawing upon decoloniality and critical race theory perspectives and activism, I define my critical scholarship as challenging the dominant oppression through thoughts and actions. Through autoethnographic and self-reflective narratives, I reflect on how my lived experiences as a Latino who has experienced criminalization. I have shaped my academic pursuits and critical consciousness. The autoethnography discusses systemic barriers such as stigma, discrimination, and institutional biases, showing how these obstacles have informed the author’s …

Faculty, Staff and Students Publications

Background: Computer perception (CP) technologies hold significant promise for advancing precision mental health care systems, given their ability to leverage algorithmic analysis of continuous, passive sensing data from wearables and smartphones (eg, behavioral activity, geolocation, vocal features, and ambient environmental data) to infer clinically meaningful behavioral and physiological states. However, successful implementation critically depends on cultivating well-founded stakeholder trust.

Objective: This study aims to investigate, across adolescents, caregivers, clinicians, and developers, the contingencies under which CP technologies are deemed trustworthy in health care.

Methods: We conducted 80 semistructured interviews with a purposive sample of adolescents (n=20) diagnosed with autism, Tourette …

Dem Simulations For Tractive Performance Of Rigid Wheel In Granular Media, Aidan Noah Dickerson

Theses and Dissertations

Accurately predicting vehicle mobility in granular media is essential for evaluating off-road mobility in agriculture, defense, and planetary exploration. Traditional empirical models often fail in capturing complex micromechanics of soil deformation, especially under dynamic conditions such as high slips and maneuvering. This study demonstrates the value of the discrete element method (DEM) in modeling wheel-soil interactions with higher fidelity. Using Altair EDEM and pre-calibrated GEMM materials, simulations were conducted for a range of forward (-5.9% to 54.8%) and side slip angles (3°, 6°, 12°) in dry sand. DEM enabled detailed analysis of sinkage, traction forces, and lateral loads, revealing trends …

Building From The Ground Up: Informing Inclusive Curriculum Design Through Qualitative Inquiry: Development Of An Early Childhood Curriculum For Children In Mississippi, Alicia Deaver

Theses and Dissertations

Curriculum is a vital component of high-quality early care and education programs. Barriers such as cost, limited education and training, and restricted access to materials often make it difficult for many programs to adopt or implement developmentally appropriate curricula. Effective curriculum implementation relies on individualization and cultural responsiveness to be fully inclusive of children of all abilities. This study addressed the formative and summative processes of the My Mississippi Adventures project, a curriculum developed for use by early childhood educators throughout the state. The curriculum was designed with direct input from early childhood educators to address the unique challenges faced …

The Bioarchaeology Of Care In An Asylum Population: Studying Health-Related Caretaking In The Mississippi State Asylum, Hannah D. Willis

Theses and Dissertations

This study employed modified versions of the Bioarchaeology of Care (BoC) and the Index of Care (IoC) to assess signs of impairment, disability, and health-related caretaking within a sample of 15 individuals buried in the Asylum Hill Cemetery who were likely former patients at the Mississippi State Asylum (MSA). This aim is to explore perceptions of disability and health-related caretaking needs through a combination of skeletal evidence and historical documents. Twelve individuals likely experienced physical impairment and potentially disability through participation restrictions. Six individuals likely required health-related caretaking, and healing lesions suggest they may have received care while at the …

Immature Bull Sharks (Carcharhinus Leucas) Of Coastal Alabama: A Formal Assessment Of Habitat Change, The ‘Shark Nursery Area’ Concept, And Facilitation Of Stakeholder Support, Lindsay Lee Mullins

Theses and Dissertations

Evaluation of long-term datasets is essential for management of nearshore, estuarine areas given their heterogeneity and high biodiversity. This is especially true for fisheries, where data deficiency often restricts informed management decisions. The Alabama Department of Conservation and Natural Resources Marine Resources Division (AMRD) has conducted gillnet sampling along the Alabama Gulf Coast since 2001, yielding a long-term dataset capable of assessing resource change responses. The region is highly dynamic, marked by high levels of biodiversity, valuable fisheries, and a population of immature bull sharks (Carcharhinus leucas). However, changing environmental conditions have altered coastal ecosystem dynamics, confounding management efforts. Here, …

Conservation Of Cis-Regulatory Codes Over Half A Billion Years Of Evolution, Yohey Ogawa, Yu Liu, Connie A Myers, Ala Morshedian, Gordon L Fain, Alapakkam P Sampath, Joseph C Corbo

2020-Current year OA Pubs

Identifying homologous cell types across species is essential for understanding cell type evolution. The retina is ideal for comparative analysis because its six major cell classes have persisted since the origin of vertebrates more than half a billion years ago. Here, we show that the retina's conserved cellular architecture is mirrored by deep conservation of the cis-regulatory codes that govern gene expression. Through single-cell chromatin accessibility analysis of lamprey, fish, bird, and mammalian retinas, we demonstrate cross-species conservation of cis-regulatory codes in all retinal cell classes despite extensive turnover of cis-regulatory regions. Conservation manifests as clustering of high-affinity transcription factor …

2020-Current year OA Pubs

BACKGROUND: Pharmacy deserts, or areas lacking convenient access to pharmacies, can limit access to medications and reduce adherence. In U.S. cities, pharmacy deserts are disproportionately concentrated in racial/ethnic minority and low-income neighborhoods. This study examined the demographics and spatial distribution of pharmacy deserts in St. Louis City, Missouri, and their associations with sociodemographic and healthcare access determinants.

METHODS: Pharmacy deserts were defined as census tract block groups whose centroids were more than 1 mile from a pharmacy, or more than a half mile and located within a tract where at least 20% of households lacked vehicle access. Demographic and socioeconomic …

Early Genetic Evolution Of Driver Mutations In Uveal Melanoma, James J Dollar, Kisha D Piggott, Et Al.

2020-Current year OA Pubs

Uveal melanoma (UM) is an aggressive eye cancer that frequently results in metastatic death despite successful primary tumor treatment. Subclinical micrometastasis is thought to occur early, when tumors are small and difficult to distinguish from benign nevi. However, the early genetic evolution of UM is poorly understood, and biomarkers for malignant transformation are lacking. Here, we perform integrated genetic profiling of 1140 primary UMs, including 131 small tumors. A clinically available 15-gene expression profile (15-GEP) prospectively validated by our group is more accurate than driver mutations for predicting patient survival. Small tumors are significantly more likely to be in earlier …

In The Mouth Or In The Gut? Innovation Through Implementing Oral And Gastrointestinal Health Science In Chronic Pain Management, Jo Nijs, Burel R Goodin, Et Al.

2020-Current year OA Pubs

Recent scientific advances point towards an important role for oral and gastrointestinal health in people with chronic pain. Poor oral health (e.g., periodontitis, tooth loss) is observed in subgroups of the chronic pain population, including abdominal pain, low back pain, fibromyalgia, and rheumatoid arthritis. In addition to poor oral health, studies have also revealed altered intestinal microbiota compositions in various types of chronic pain, including people with chronic low back pain, knee osteoarthritis, visceral pain, fibromyalgia, tinnitus, and migraine. While overweight/obesity contributes to the likelihood of gut dysbiosis, normal-weight individuals with chronic pain also more often present with poor gut …

Distributed 48 V Energy Nodes (D48en), Hieu Nguyen

Defensive Publications Series

This document introduces the Distributed 48 V Energy Node (D48EN) architecture, a modular approach to home and community-scale energy storage and power distribution. Unlike conventional DC microgrids that rely on a continuous shared bus, this architecture places independent 48 V battery nodes throughout a structure, each with its own point-of-load photovoltaic (PV) input and short-run DC distribution to nearby loads. Nodes are normally isolated electrically and do not form a high-power backbone. Instead, low-current redistribution links allow controlled, schedulable energy sharing between nodes. This configuration reduces wiring cost, improves safety, simplifies retrofits, and enables modular growth for both developed residential …

Motion Gesture And Near-Field Communication Field Detection For Initiating Wearable Payments, Malcolm Kemeny, Sergio Alves, Michael Angermann, Andrew Chen, Annie Tran, Brian Julian

Defensive Publications Series

Some methods for making payments with a wearable computing device, such as a smart watch, can involve manual steps like waking the device and opening a payment application, which may introduce latency into the transaction process. The disclosed technology provides an approach for initiating payments by using sensor data to detect an indication of a user's intent to pay. For example, a system can analyze data from a sensor, such as an accelerometer, to detect a predefined motion gesture. The detection of this gesture, in combination with the contemporaneous presence of a near-field communication (NFC) field from a payment terminal, …

Unpacking Identity Work Mechanisms For A Person-Centered Approach To Business And Management Education, Carla Campana, Pablo Leao

International Journal of Teaching and Learning in Higher Education

We explore identity work among undergraduate business students who resist the identity prevailing in traditional business schools. The study investigates an educational program that fosters identity work, allowing students to add facets to their emergent identity. Through in-depth interviews, the researchers uncovered a process in which students resist the hegemonic identity of business administrators, seeking alternative experiences that redefine their identity. Our research contribution is two-fold. First, we extend the concept of identity workspaces by introducing three mechanisms: autonomy, a psychological safe space, and group embeddedness. These mechanisms enable students to engage in an identity work process and reidentify with …
