International Journal of Speleology

Fires occurring in cave guano are a rare and unusual phenomenon and the occurrence of such events in Southeast Asia is particularly novel. In this study, we document the first recorded instance of a bat guano fire in a tropical cave at Tham Chao Ram in Sukhothai province, northern Thailand. A bacteriological analysis was made of the guano at the fire site and from a control site within the cave. We give a comprehensive review of global reports on bat guano fires in caves, conduct an initial investigation of the physical factors at the fire site and discuss the potential …


The Relationship Between Lineaments And Cave Passages In Unfaulted Gently-Folded Strata, Snail Shell Cave, Central Tennessee, Usa, Mark Abolins, Joseph Firkaly-Paciera, Blake King, Cris Ocasio-Valentin, Jackson Slighter, Teagan Sullivan, Justin Whited Nov 2025

The Relationship Between Lineaments And Cave Passages In Unfaulted Gently-Folded Strata, Snail Shell Cave, Central Tennessee, Usa, Mark Abolins, Joseph Firkaly-Paciera, Blake King, Cris Ocasio-Valentin, Jackson Slighter, Teagan Sullivan, Justin Whited

International Journal of Speleology

Near Snail Shell Cave in central Tennessee, USA, seven image interpreters independently mapped lineaments using a 3DEP LiDAR DTM, revealing geomorphic and structural differences in and near different parts of the cave. MANOVA comparison of lineament and cave passage trend for Western, Central, and Eastern Snail Shell caves reveals statistically significant differences (p <0.05). The Western cave (mean depth 44 m) is in the gently-dipping limb of the Snail Shell anticline, and the Central cave (mean depth 31 m) is in the anticline hinge. In contrast, many Eastern cave passages (mean depth 40 m) cut across the anticline hinge and part of the limb of the Overall syncline. For both the Western and Central caves, a post-hoc Tukey’s HSD test fails to show that lineament trend within 235 m of the cave differs significantly from passage trend, and the test fails to show that the two differ significantly within 235 and 433 m of the Eastern cave. Additional statistical testing fails to show a difference between Western passage trend and bed strike, indicating the likelihood that lineaments and passages developed within strike-joints. However, testing shows a statistically significant difference between passage trend and bed strike for the Central and Eastern caves. The strike of joints inside the Eastern cave shows that it is within a joint zone which penetrates to depths of at least 80 m and is expressed at the surface as an ~4.2 km-long belt of elevated lineament line density. The lack of a statistically significant difference between Eastern passage trend and the trend of a nearby topographic escarpment suggests that many joints are stress release fractures formed during relatively recent erosion. For the Eastern cave, intersections between lineaments and structures would be attractive targets for groundwater exploration at depths typical of wells in carbonates.


A Bioarchaeological Study Of The Individuals From The Városfalva Burial Mound In Transylvania, Romania (15th-19th Century), Vanessa C. Reeves Nov 2025

A Bioarchaeological Study Of The Individuals From The Városfalva Burial Mound In Transylvania, Romania (15th-19th Century), Vanessa C. Reeves

USF Tampa Graduate Theses and Dissertations

This study explores the lives and deaths of the Szekler people recovered from a burial mound in the Transylvanian village of Városfalva. The Transylvanian plateau is located in present day Romania, and is protected on the east and the south by the Carpathian Mountains. The Szekler people arrived in this area around 1000 CE, and were a nomadic group originating in the Asian Steppes region who later intermarried with various migratory groups as they moved across the Eurasian plains. The Szeklers eventually banded together with the proto-Hungarian Magyar peoples and settled in the Carpathian Basin, the easternmost frontier of the …

Evaluating Student Proficiency In Quantitative Reasoning, Gabriel Chavez, Jennifer Clinkenbeard, Tolga Tezcan, Celine Pinet, Jennifer Duggan, George Beckham, Sumadhur Shakya, Christina Zhang

Numeracy

Quantitative Reasoning (QR) competencies are increasingly vital for academic and professional success across disciplines. This study examines the QR proficiency of over 400 undergraduates through a mixed-methods approach, integrating survey-based self-assessments (n = 469) with direct evaluations of final exams (n = 80). This study took place at a public, primarily undergraduate, four-year state university in Northern California with approximate enrollment of 7,500 students. Although students reported frequent engagement in foundational QR tasks— such as calculation and interpretation—rubric-based scoring revealed inconsistent levels of mastery, particularly on higher-order skills like evaluation and coherence. Regression analyses linked confidence to calculation …


Does The National Benchmark Quantitative Literacy Test Predict Performance In Stem Programmes In Commerce, Engineering And Science?, Robert N. Prince Nov 2025

Does The National Benchmark Quantitative Literacy Test Predict Performance In Stem Programmes In Commerce, Engineering And Science?, Robert N. Prince

Numeracy

In South Africa, university completion rates remain low, with only 23% of students finishing within the regulation time (three or four years). These completion rates continue to reflect racial inequalities, with ‘White’ students significantly more likely to complete degrees in professional fields such as engineering and commerce compared to their ‘African’ counterparts. To address these challenges, the South African higher education institutions, through their umbrella body, introduced the National Benchmark (NB) tests to assess students’ academic literacy skills—including quantitative literacy, academic literacy, and mathematics—to identify those most at risk of struggling with the curriculum. The NB tests aim to evaluate …


“For Haitian Culture, Being Older [Is] A Blessing”: Perceptions Of Aging, Elderhood, And Dementia In A Haitian Born Sample, Melissa K. Eustache Nov 2025

“For Haitian Culture, Being Older [Is] A Blessing”: Perceptions Of Aging, Elderhood, And Dementia In A Haitian Born Sample, Melissa K. Eustache

USF Tampa Graduate Theses and Dissertations

This thesis investigates how first-generation Haitian immigrants in the United States understand and interpret dementia within the intersecting contexts of culture, migration, and biomedicine. While dementia is constructed as a pathological “loss of self” and a public health epidemic, in American biomedical and popular discourse, this study examines how Haitian-born individuals—socialized within a non-Western cultural and spiritual framework—make sense of cognitive decline and impairment in ways that diverge from Western biomedical narratives. Guided by theoretical orientations from medical anthropology, including Mark Nichter’s idioms of distress, Margaret Lock’s local biologies, and neuroanthropology, this research explores how cultural models of illness, aging, …


Reducing Data Requirements In Polymer Science: Deep Neural Networks For Predicting Surface Tension Of Copolymer Compatibilizers, Md Mushfiqul Islam Nov 2025

Reducing Data Requirements In Polymer Science: Deep Neural Networks For Predicting Surface Tension Of Copolymer Compatibilizers, Md Mushfiqul Islam

USF Tampa Graduate Theses and Dissertations

In polymer chemistry, compatibilization involves adding a substance often a block or graft copolymerto stabilize polymer blends that would otherwise not mix well, leading to rough structures and weak me- chanical properties. Compatibilizers improve miscibility and reduce interfacial tension, which is critical for applications such as mixed-waste polymer recycling. Sequence-controlled polymers offer unique potential by combining the tunable chemistry of synthetic polymers with the precise, function-driven design of biological macromolecules, but unlike proteins, they lack large, evolution-shaped datasets to guide discovery. This research develops a deep learning framework to predict the surface tension of sequence-controlled copolymer compatibilizers across varying concentrations. …

An Unusual Case Of Common Terns Nesting On A Rooftop In Ontario And An Attempt To Relocate The Colony, David J. Moore, Jeffrey N. Costa, Alexis L. Stupich Nov 2025

An Unusual Case Of Common Terns Nesting On A Rooftop In Ontario And An Attempt To Relocate The Colony, David J. Moore, Jeffrey N. Costa, Alexis L. Stupich

Ontario Birds

A variety of gull and tern species have adapted to urban environments by nesting on rooftops and other human-made structures. Previous reports of Common Terns (Sterna hirundo) breeding on rooftops have generally involved small numbers of nests (≤25). Here, we report an occurrence of an unusually large number of Common Terns nesting on a rooftop in Port Credit, Ontario, in 2013. A complete survey of the roof was conducted on 31 May, when 1,011 Common Tern nests were counted. A similar number of breeding pairs used this roof in 2014, but the site was largely abandoned by 2015, due to …

Changes In Agricultural Land Use And The Effectiveness Of Protected Areas: Impacts On The Occurrence Of Three Grassland Bird Species In The Carden Plain Of Ontario, Alice L. Merondun, Ginny Moore, Ron Reid, Erica Nol

Ontario Birds

We measure changes in occurrence (i.e., presence/absence) of three grassland bird species in the Carden Plain, between 2001 to 2005 and 2015 to 2016, by comparing point count results of the 2001–2005 Ontario Breeding Bird Atlas (OBBA) to repeated point counts at the same sites in the more recent period. We examine associations between changes of occurrence and habitat change and protection status of the survey locations for the three most commonly occurring species of Ontario grassland birds (Bobolink, Dolichonyx oryzivorus; Eastern Meadowlark, Sturnella magna; and Savannah Sparrow, Passerculus sandwichensis), all of which have experienced population declines in Ontario of …
