High-Resolution Mapping Of Soil Moisture Variation Using Uas Thermal And Multispectral Imagery, Jackline Amma Timah

Theses and Dissertations

In agricultural landscapes, soil moisture regulates hydrologic partitioning, nutrient transport and water quality, land-atmosphere energy exchange that shapes local climate, and ecosystem resilience. However, traditional monitoring approaches, such as in-situ sensors and satellite imagery, often lack the spatial resolution required to capture fine-scale soil moisture variability. This study evaluated whether unmanned aerial system (UAS)-derived thermal, multispectral, and terrain variables can capture fine-scale spatial variability in volumetric water content (VWC) within an SRB in central Illinois.

High-resolution imagery was collected and paired with 50 field-measured VWC observations. Land surface temperature (LST), vegetation indices (NDVI and NDRE), spectral bands, and slope were …

Investigating Intersectionality: How Multiple Marginalized Identities And Social Perceptions Of Victims Influences The Efficacy Of Panic-Defense Narratives In Bathooms, Demitri James Aguilar

Theses and Dissertations--Psychology

Despite transgender Women of Color being the main victims of violent victimization and panic-narrative cases, very little research has investigated how race/ethnicity might impact perceptions of violence or the influence of panic-narratives. Thus, the current experiment (N = 1275) examined the social and legal ramifications of using panic-narratives against transgender and cisgender women of color (Black vs. Latino vs. White) in bathroom victimization contexts. The predictions were partially supported. Regardless of racial identity, the justification of transgender (versus cisgender) victimization via panic-narratives produced more anti-victim (e.g., increased victim guilty verdicts, sentencing, victim culpability, perceived deception, and threat) and prodefendant outcomes …

Brief Exposure Therapy With Exercise For Ptsd: A Pilot Study Using Single Case Experimental Design, Troy J.J. Hubert
