Understanding Familicide: Psychosocial, Behavioral, And Mental Health Risk Factors And Implications For Forensic Behavioral Health Professionals, Molly M. Vogl Aug 2026

Understanding Familicide: Psychosocial, Behavioral, And Mental Health Risk Factors And Implications For Forensic Behavioral Health Professionals, Molly M. Vogl

Master of Arts in Human Services

Familicide is a rare but devastating form of family violence involving the killing of multiple family members by another family member. Although research examining domestic violence, homicide, and homicide-suicide has expanded, familicide remains less understood due to its low occurrence and complex nature. This capstone examined the psychosocial, behavioral, and mental health risk factors commonly associated with familicide perpetrators and explored how forensic behavioral health professionals may use this information to improve violence risk assessment, prevention, and intervention efforts. A review of peer-reviewed research from academic databases and scholarly search engines identified common themes associated with familicide, including relationship conflict, …

Islamic Business Ethics, Muslim Feminism, And The Rhetorical Construction Of Entrepreneurial Legitimacy: Evidence From Emirati Women, Hayfaa A. Tlaiss, Valerie Priscilla Goby

All Works

Despite the United Arab Emirates’ state-led promotion of women’s entrepreneurship as central to national transformation, Emirati women entrepreneurs continue to face patriarchal norms that frame entrepreneurship as a masculine domain, rendering their entrepreneurial legitimacy both precarious and contested. Based on in-depth interviews, this study examines how women entrepreneurs construct entrepreneurial legitimacy within a patriarchal Muslim context, marked by a tension between empowerment rhetoric and gendered constraints. Drawing on Suddaby and Greenwood’s (2005) framework of rhetorical legitimation together with Islamic business ethics and Muslim feminism, we demonstrate how Emirati women entrepreneurs mobilise state-led empowerment and national transformation discourses to construct entrepreneurial …

From Evidence To Impact: Academic-Clinical Partnership As A Mentorship Accelerator, Jackeline Iseler, Joshua Winowiecki

International Nursing Research Congress (INRC)

Formal mentorship is widely recognized for strengthening nurses’ evidence-based practice (EBP) competencies and supporting nurse-led research, yet persistent gaps remain between academic preparation and clinical translation. This project synthesizes existing literature and cross-institutional case results to examine how mentorship, when fully embedded in Academic-Clinical Partnership (ACP) infrastructure, catalyzes system-level transformation that extends beyond individual gains.

We integrated a literature synthesis of nine studies with a multi-site case analysis across two ACPs:

1. A large community hospital with a structured mentorship program supporting frontline EBP/QI and research initiatives.

2. A large multi-hospital system piloting a structured academic-clinical mentorship initiative, pairing clinical …

Hydrogels For Local Drug Delivery In Biofilm-Associated Periprosthetic Joint Infection: Current Progress And Future Directions, Karolina Kraus, Pawel Mikziński, Bindu Subhadra, Emil Paluch

Faculty Publications - Biological Sciences

Periprosthetic joint infection (PJI) remains one of the most serious complications of arthroplasty, largely due to the formation of microbial biofilms on implant surfaces. Biofilm-associated infections exhibit increased tolerance to antimicrobial therapy and host immune responses, making eradication difficult and often requiring repeated surgical interventions. Consequently, there is a growing need for effective local therapeutic strategies capable of delivering high concentrations of antimicrobial agents directly to the site of infection while minimizing systemic toxicity. Hydrogels have emerged as promising drug delivery platforms for the management of biofilm-associated PJI. Their biocompatibility, injectability, high water content, and tunable physicochemical properties enable controlled …

Massively Parallel Characterization Of Rna G-Quadruplex Stability And Molecular Recognition, Rebekah L Rothacher, Francisco F Cavazos, Yue Hu, Rhese D Thompson, Anthony M Mustoe, Maria M Aleman, Daniel Dominguez

Faculty, Staff and Students Publications

RNA G-quadruplexes (rG4s) have been implicated as important regulators of RNA metabolism and are promising targets for RNA-targeted therapeutics. rG4s typically require a canonical (G≥2N1-7)4 motif, but the sequence features that affect rG4 stability and recognition by RNA-binding proteins (RBPs) and rG4-binding ligands are not fully understood. To interrogate sequence-level drivers of rG4 folding, we applied a reverse-transcriptase stop sequencing strategy to a library of ∼3000 synthetic rG4s with varied G-tract lengths, loop lengths, and loop compositions, permitting massively parallel quantification of rG4 stability. Our data confirm known sequence-level features and characterize novel combinatorial impacts of these features. We also …

Faculty, Staff and Students Publications

Most biological processes are dynamic, yet experimental methods predominantly rely on steady-state measurements to investigate their underlying mechanisms. RNA localization is a fundamental aspect of eukaryotic cell organization and is dynamically regulated by cells. While extensively studied in specialized cell types for a limited number of candidate RNAs, the general principles governing dynamic RNA localization at a transcriptome-wide scale remain largely unexplored. Existing transcriptome-wide studies provide only a static snapshot of RNAs residing in specific cellular locales, in part due to the limited availability of tools for probing cellular spatial organization at biologically relevant scales. Here, we leverage the high …

Fabrication Of Photoresist Su-8 Pyrolyzed Carbon Electrodes And Their Integration In A Microfluidic Hematocrit Detection System, Hwi Yong Lee, Jessika A. Rogers, Chito Kendrick, Sanaz Habibi, Adrienne Minerick

Michigan Tech Publications

Carbon microelectrodes are attractive for microfluidic biosensing due to their wide potential window, low overpotentials, chemical stability, and compatibility with low-cost microfabrication. Pyrolysis of photopatterned SU-8 offers a scalable route to carbon electrode fabrication; however, conventional two-step pyrolysis often leads to adhesion issues, geometric distortion, and limited surface area in low-aspect-ratio planar designs. These constraints restrict performance and broader adoption in analytical microdevices. Hematocrit determination, a clinically essential diagnostic measurement, requires electrodes with high reproducibility and robust electrochemical response. A simplified fabrication strategy that improves electrode surface area and performance while maintaining low-aspect-ratio planar geometries remains unresolved. We developed a …

Advanced Ai Deployment On Smallsats: A Mixed Precision Approach To Onboard Perception And Fpga-Gated Inference, Margaret Michelsen, Jackson Gardner, Shawn Jones, Jackson Kulik, Mario Harper Aug 2026

Advanced Ai Deployment On Smallsats: A Mixed Precision Approach To Onboard Perception And Fpga-Gated Inference, Margaret Michelsen, Jackson Gardner, Shawn Jones, Jackson Kulik, Mario Harper

Small Satellite Conference

MOTIVATION:

SmallSats are asked to make time-sensitive calls (vessel detection, cloud filtering, debris tracking) but CubeSat-class compute is starved for power, memory, and radiation-tolerant silicon.

Most missions still downlink raw imagery for ground processing, costing hours-to-days of latency and scarce bandwidth. Running inference onboard means solving two separate problems:

  • When to run inference: compute and power budgets can’t tolerate a neural network firing on every frame.
  • Whether it fits when it does run: the model has to live inside a memory and compute envelope measured in megabytes, not gigabytes.


Characterizing Rolling-Shutter Distortions In A 1u Cubesat Camera Using Led Strobe Imaging, Sharon Chan, Arseniy Dolgov, Andrea Schildhorn, Jenny Zhu, David Michelson Aug 2026

Characterizing Rolling-Shutter Distortions In A 1u Cubesat Camera Using Led Strobe Imaging, Sharon Chan, Arseniy Dolgov, Andrea Schildhorn, Jenny Zhu, David Michelson

Small Satellite Conference

The ArduCAM OV5642 rolling shutter sensor was selected for ALEASAT because its simpler design results in reduced cost, power consumption, and heat generation. Although rolling shutter readout can introduce image skew due to the relative motion between the CubeSat and Earth, these sensors provide sufficient resolution and sensitivity within mission constraints. The feasibility of de-skewing, therefore, depends on the stability and predictability of the rolling shutter readout. Camera testing is not currently included in ISO 19683 (Space Systems – Design qualification and acceptance tests of small spacecraft and units). This work could be a step towards addressing that omission.

Development Of A Design Tool For 3d-Printable Cold Gas Thruster Systems For Nanosatellite Missions, Mikolaj Szyszka, Katherine Smith Aug 2026

Development Of A Design Tool For 3d-Printable Cold Gas Thruster Systems For Nanosatellite Missions, Mikolaj Szyszka, Katherine Smith

Small Satellite Conference

Currently, there are 5219 Nanosatellites and CubeSats in orbit [1]. A decade ago, this number was only 800 [1], with forecasts predicting a total of 14,000 small satellites in orbit by 2033 [2]. However, out of the ones that are currently operational, only about 5% are equipped with a propulsion system. Omitting the electric and classified thrusters, cold gas systems are the most popular due to their simplicity and ease of operation. This shows a general lack of manoeuvrability and agility within small satellites in orbit. The proposed C.O.N.E tool aims to bridge the gap between nanosatellite manufacturers and simple …

Feasibility Study Of Nofb Propulsion Systems For Multi-Altitude Earth Observation Missions, Jingeon Kim, Eunwoo Jung, Minwoo Lee

Small Satellite Conference

  • Earth observation (EO) satellites represent the largest and fastest growing segment of the satellite industry [1].
  • Higher imaging resolution can be achieved either by enlarging the optical system-which increases satellite dry mass-or by lowering operational altitude, where increased atmospheric drag demands continuous propulsive orbit maintenance[2].
  • At Low Earth Orbit (LEO) and Very Low Earth Orbit (VLEO), atmospheric drag increases significantly, requiring a dedicated propulsion system for sustained orbit maintenance.
  • Hydrazine (N2H4) has been the conventional propellant choice, but its high toxicity incurs substantial handling costs, and its low vapor pressure necessitates a …


Multi-Satellite Optical Link Scheduling With Direct Nonlinear Attitude Planning, Leif Nelson, Yung-Jai Pomeroy, Daniel J. Garcia Aug 2026

Multi-Satellite Optical Link Scheduling With Direct Nonlinear Attitude Planning, Leif Nelson, Yung-Jai Pomeroy, Daniel J. Garcia

Small Satellite Conference

The Problem:

Low Earth Orbit (LEO) constellations increasingly rely on Optical Inter-Satellite Links (OISL) to route data across dynamic satellite networks. As satellites move through their orbits, communications continuously change due to line-of-sight constraints, link quality variations, and spacecraft pointing limitations. Traditional routing approaches often consider network optimization separately from spacecraft attitude control, creating a disconnect between planned routes and physically achievable communication links. This work addresses the challenge of simultaneously generating communication routes while validating that satellites can physically point toward their assigned target. The result is an end-to-end framework that integrates network planning, optical link feasibility, and spacecraft …
