Mechanically Modulated Photothermal Dynamics In Au-Pdms Nanocomposites For Non-Contact Stress Sensing, Woosuk Chung, Rengaraj Selvaraj, Younghun Kim

Sultan Qaboos University Journal For Science

Photothermal films used in flexible and wearable devices are inevitably exposed to mechanical deformation, yet their thermal response under such conditions remains poorly quantified. In this work, gold nanoparticle–embedded polydimethylsiloxane (Au@PDMS) films are fabricated and their photothermal behavior is examined under controlled stretching, bending, twisting, and curved-surface attachment. Gold nanoparticles were formed in situ in the PDMS matrix, producing uniformly dispersed, spherical nanocrystals with retained crystallinity. Systematic variation of Au loading reveals a proportional increase in optical absorption and light-to-heat conversion efficiency without significant aggregation. Under near-infrared irradiation (808 nm), the Au@PDMS films exhibit rapid and repeatable temperature modulation. Mechanical …

Same Interdependent Risk, Different Valuation: How Risk Representation Shapes Ecosystem Investment Decisions, Shiyao Bao, Jiamin Zhao, En Yang, Llewellyn D. W. Thomas, Hansjörg Neth, Jan K. Woike, Sebastian Hafenbrädl

School of Psychology

Why do decision makers value the same risky opportunity differently when the underlying probability of success is unchanged? We study this question in ecosystem investment decisions, where success requires that none of the critical components fail, causing component risks to compound. We conducted a high-powered preregistered replication and extension of Adner and Feiler's key study (N = 3,600). Participants valued a $100,000 opportunity that required six independent components to succeed, each with a 75% chance of success, yielding an overall success probability of ≈18%. Replicating prior work, participants reported higher confidence and assigned higher valuations when they first saw the …

Measuring Maintainable Income Under Natural Capital Depletion: A Dynamic Sustainability-Weighted Cost Of Capital Framework, Khaled Aldhaferi

Journal of King Abdulaziz University: Economics and Administration

Sustainability reporting has improved the visibility of climate, resource, and safety risks, but it still does not provide a measurement mechanism for separating maintainable operating surplus from income generated by depleting finite natural capital. This paper develops Dynamic Sustainability-Weighted Cost of Capital (Dynamic SWACC) as a governed shadow-accounting architecture for estimating sustainability-adjusted maintainable income. The framework begins from the Hicksian capital-maintenance view of income and the El-Serafy user-cost method, derives the user-cost charge from a finite-horizon operating-surplus annuity, and endogenizes the discount rate through auditable state variables: reserve-life constraint intensity, carbon-budget utilization, and operational safety risk. The developed contribution extends …

From Minimum To Meaningful: A Use Of Force Training Regimen For Rural Police Departments, Joseph Corley

Dissertations, Theses, and Projects

This paper examines how small and rural law enforcement agencies can improve use of force training despite limited staffing, budgets, and training opportunities. Current Minnesota POST Board minimum standards establish baseline requirements but allow significant variation in how agencies develop and deliver training, contributing to inconsistent officer preparedness and skill retention. Drawing on current research in police training, motor skill retention, and scenario based learning, this paper argues that infrequent, skills based training is insufficient for preparing officers to manage dynamic, high risk encounters. The paper proposes an evidence based training regimen centered on two department led use of force …
