A Narrative Investigation Of Black Familial Capital That Supports Engineering Engagement Of Middle-School-Aged Youth, Delean Tolbert Smith, Tamecia Jones, Monica E. Cardella Jun 2022

A Narrative Investigation Of Black Familial Capital That Supports Engineering Engagement Of Middle-School-Aged Youth, Delean Tolbert Smith, Tamecia Jones, Monica E. Cardella

Journal of Pre-College Engineering Education Research (J-PEER)

A major concern in engineering education involves ensuring that youth belonging to minoritized groups have equitable access to engineering career pathways. Related research often highlights the effect of student and school characteristics on engineering success but few studies have investigated the engineering-related assets that Black families provide. This work aims to provide counterstories that highlight the presence of Black families along the pre-college engineering pathways of three Black youth from the Midwest region of the United States. The application of a counternarrative approach centers the familial capital of Black families and serves as the analytical frame for this work. The …


A Finite Difference Approach For Predicting Acoustic Behavior Of The Poro-Elastic Particle Stacks, Zhuang Mo, Guochenhao Song, J Stuart Bolton Jun 2022

A Finite Difference Approach For Predicting Acoustic Behavior Of The Poro-Elastic Particle Stacks, Zhuang Mo, Guochenhao Song, J Stuart Bolton

Publications of the Ray W. Herrick Laboratories

The physical properties of particle stacks have been of interest for a long time, and the acoustic properties of such materials have been actively investigated in recent times. Traditional acoustic theories, such as the Biot theory, can serve as a guide for determining the general properties of the stacks, but they do not allow the identification of the differences between the particle stacks and traditional acoustic materials, which are usually modeled as homogeneous continua. Recent research suggests that the Biot theory, combined with depth-dependent stiffness and equivalent density, can be used to model such materials. In this work, a finite …

Heart Rate And Age Modulate Retinal Pulsatile Patterns, Ivana Labounková, René Labounek, Radim Kolář, Ralf P. Tornow, Charles F. Babbs, Collin M. Mcclelland, Benjamin R. Miller, Igor Nestrašil Jun 2022

Heart Rate And Age Modulate Retinal Pulsatile Patterns, Ivana Labounková, René Labounek, Radim Kolář, Ralf P. Tornow, Charles F. Babbs, Collin M. Mcclelland, Benjamin R. Miller, Igor Nestrašil

Weldon School of Biomedical Engineering Faculty Publications

Theoretical models of retinal hemodynamics showed the modulation of retinal pulsatile patterns (RPPs) by heart rate (HR), yet in-vivo validation and scientific merit of this biological process is lacking. Such evidence is critical for result interpretation, study design, and (patho-)physiological modeling of human biology spanning applications in various medical specialties. In retinal hemodynamic video-recordings, we characterize the morphology of RPPs and assess the impact of modulation by HR or other variables. Principal component analysis isolated two RPPs, i.e., spontaneous venous pulsation (SVP) and optic cup pulsation (OCP). Heart rate modulated SVP and OCP morphology (pFDR < 0.05); age modulated SVP morphology (pFDR < 0.05). In addition, age and HR demonstrated the effect on between-group differences. This knowledge greatly affects future study designs, analyses of between-group differences in RPPs, and biophysical models investigating relationships between RPPs, intracranial, intraocular pressures, and cardiovascular physiology.
