Journal of Global Education and Research
A sample of higher education students in Canada and China was surveyed and interviewed to ascertain any changes in their educational expectations given their experiences with emergency remote teaching during the pandemic. In addition, the instructors of these students were interviewed to corroborate student feedback. The research suggested that students in Canada and China expressed expectations of increased flexibility and improved pedagogy. Whereas Canadian students were overtly demanding of the instructor and the educational system, Chinese students were comparatively subtle in their expectation that the post-pandemic level of support be maintained. The primary concern of the Chinese cohort was a …

Hidden Thermal Signatures Reveal The Microclimatic Influence Of Scheduled Cave Tourism, Matt Rowberry, John Gunn, Andrew Smith
Hidden Thermal Signatures Reveal The Microclimatic Influence Of Scheduled Cave Tourism, Matt Rowberry, John Gunn, Andrew Smith
International Journal of Speleology
Tourist activity is widely recognised as a source of cave microclimate disturbance, yet visitor-induced variability is difficult to distinguish from natural environmental fluctuations. The coronavirus pandemic created a natural experiment at Poole’s Cavern, United Kingdom, in which periods of complete closure could be compared with contrasting visitor access regimes. Two years of high resolution temperature records from six monitoring points were analysed. Harmonic regression and a state space model removed deterministic diurnal cycles and lower frequency temperature variability. The remaining residual variability differed systematically among visitor access regimes and between daytime and nighttime conditions. Spectral analysis of the residuals identified …

Visitor Perceptions Of Lampenflora And Implications For Adaptive Show Cave Management: A Case Study From Ryusen-Do Cave, Japan, Kanato Ando, Kazuhide Nakajima, Shuji Watanabe, Masuo Komukai, Hidesato Kuwahara
International Journal of Speleology
Artificial lighting in show caves promotes lampenflora growth, altering cave ecosystems and posing persistent management challenges. Although various control methods have been proposed, their effectiveness and social acceptance remain context dependent. This study investigated visitors’ perceptions of lampenflora through questionnaire surveys and semi-structured interviews to explore adaptive management strategies. Results indicated that visitors generally held positive impressions of lampenflora, but these impressions became more critical after receiving information about its artificial origin and ecological impacts. At the same time, support for conservation-oriented management, including willingness to contribute financially, tended to increase following information provision. Tourism-related evaluations were more strongly associated …

Did Seismic Events Trigger The Growth Of Aragonitic Speleothems In Mawmluh Cave, North-East India?, Dildi Dildi, Dana Riechelmann Dr., Michael Weber Dr., Anne Jantschke Dr., Regina Mertz-Kraus Dr., Denis Scholz Dr.
International Journal of Speleology
Mawmluh Cave, north-east India, is located in a seismically very active region within the Himalayas with frequent earthquakes of varying magnitude. So far, speleothems from the cave have mainly been used to reconstruct past monsoon variability. The potential effect of seismic events on speleothem formation in Mawmluh Cave, however, has not been studied in detail yet. We investigated three stalagmites from Mawmluh Cave, each predominantly consisting of calcite overlain by substantially younger aragonite at the top (i.e., an aragonite ‘cap’). 230Th/U-dating shows that the initiation of aragonite growth occurred between 1859 and 1950 CE in agreement with previous studies. The …

Related Arts Teachers In A Professional Learning Community: On The Phenomenon Of Implementation, Noah Friedman
Related Arts Teachers In A Professional Learning Community: On The Phenomenon Of Implementation, Noah Friedman
Journal of Practitioner Research
In recent decades, the popularity of teacher collaboration and data-driven instructional practices has seen the increased use of the professional learning community (PLC) model as a method for school improvement. Within the PLC framework are singletons, educators who are the only ones who teach their subject in their buildings (Hansen, 2015). In elementary school settings, related arts teams (e.g. music, art, physical education, and so on) are often included in a PLC as an afterthought. To accommodate the distinctive needs of this team, I created an intervention tool and method to provide support to related arts teams as they implement …

The Role Of Emotions In Understanding Inquiry As Stance, Yun-Chen Yen, Rachel Wolkenhauer
Journal of Practitioner Research
This case study of a Taiwanese teacher candidate’s inquiry experience during her internship uses emotions as a lens for analyzing how she developed and refined her inquiry stance as a critical habit of mind. Using emotions as points of reflection and action, the teacher candidate came to see herself as a responsible and critical generator of knowledge, understood practice as a synthesis of reflection and action, and reframed the purpose of inquiry as elevating student voices and cultivating teacher curiosity. An inquiry community played a critical role in sustaining her engagement and commitment. This study suggests that teacher emotions can …

Attention-Enhanced Multimodal Fusion Of Elevation And Aerial Imagery For Sinkhole Segmentation, Junfeng Zhu, Desireé Cunningham, Nathan Jacobs
Sinkhole Conference 2026
Image segmentation, the task of assigning a class label to each pixel in an image, has been widely applied in remote sensing to identify surficial geological and hydrological features from data sources such as multispectral satellite imagery, aerial photography, and digital elevation models. UNet is among the most widely adopted convolutional neural network architectures for segmentation, owing to its encoder–decoder structure and skip connections that enable precise spatial localization. UNet has been applied to detect sinkholes using lidar-derived high-resolution digital elevation data; however, existing models still fall short of the accuracy of manual sinkhole mapping. In this study, we aim …

Comparing Manual And Automated Methods In Sinkhole Delineation: A Cantabrian Mountains (Spain) And Tasman Mountains (New Zealand) Case Study, Mario Puente-Sierra, Javier Santos-González, Rosa B. González-Gutiérrez
Sinkhole Conference 2026
Studies of karst landforms, such as sinkholes, have advanced in recent years due to technological advances and the rise of automated detection methods. Such methods offer notable time-saving strengths, but their limitations in complex terrains are frequently overlooked in modern literature. To compare these automated methods to traditional manual methods, we selected four karst massifs in the Cantabrian Mountains (Spain) and two in the Tasman Mountains (New Zealand) as study areas. High-resolution LiDAR-derived Digital Elevation Models were used to identify and map sinkholes. Automated detection was performed using a Geographic Information System and included: i) a depression-filling method; ii) a …
Statewide Sinkhole Susceptibility Mapping In Florida Using Explainable Geoai, Osama M. Altarawneh, Weiwei Zhan, Clint Kromhout
Statewide Sinkhole Susceptibility Mapping In Florida Using Explainable Geoai, Osama M. Altarawneh, Weiwei Zhan, Clint Kromhout
Sinkhole Conference 2026
Sinkholes cause persistent damage to infrastructure, property, and groundwater resources across Florida. Statewide sinkhole hazard mitigation has been constrained by incomplete inventories and the absence of a high-resolution susceptibility map. This study presents a statewide sinkhole susceptibility assessment using an explainable GeoAI framework that integrates the citizen-reported Subsidence Incident Reports (SIR) database and a geologist-confirmed collapse-type sinkhole inventory from the Florida Geological Survey (FGS). Random Forest (RF) is used as the primary learner with ten geologic, hydrologic, topographic, and anthropogenic predictors. The influence of negative-sample buffer geometry on model behavior is evaluated across five annular buffer conditions (100-1000 m through …

Mobile Lidar Scans Of Caves: Methods For Tying In Ground Control Points, Robert E. Salaz, Jake Slyder, Ellen Trautner, Georgia Schneider
Sinkhole Conference 2026
Mapping cave passages using modern techniques such as Light Detection and Ranging (LiDAR) and photogrammetry are still in the juvenile stages. Newer technologies such as Simultaneous Location and Mapping (SLAM) LiDAR and faster computers have enabled speleologists to map caves much faster than traditional methods. From a land management perspective, the ability to efficiently collect detailed cave maps with reasonable precision quickly is crucial for decision making. The ongoing challenge with digital cave mapping using mobile LiDAR and photogrammetry techniques is geolocating the point-cloud underground. Mobile scanning methods can be tied to ground control points on the surface using high …

Mapping Sinkholes And Closed Depressions In The Edwards Aquifer Recharge Zone: Comparison Of Lidar-Based Semi-Automated Detection Methods And Field Validation, Enzo Franceschi Genesi, Horia G. Olariu, Bradford Wilcox
Sinkhole Conference 2026
Sinkholes and closed depressions play a critical role in karst hydrology by facilitating rapid recharge to aquifer systems (Ford & Williams, 2007; White, 1988), yet their spatial distribution is often poorly quantified in large recharge zones, and the automated methods used to detect them vary widely in approach and reliability. This study compares three LiDAR-based automated detection methods to determine their relative performance for mapping sinkholes and closed depressions within the Edwards Aquifer Recharge Zone, using a 0.5-meter resolution bare-earth Digital Elevation Model derived from high-density airborne LiDAR point cloud data (12.66 points/m²) obtained from OpenTopography. The three methods evaluated …

Sinkhole Hazards, Risks, And Remediation: A Fifty-Year Case Study In New Jersey, Usa, Oladoyin Kolawole, Rita L. Sousa, Christina Comuso, Mohab Hussein
Sinkhole Conference 2026
New Jersey presents a uniquely complex sinkhole and ground subsidence hazard shaped by intersecting geological, industrial, and anthropogenic forces. Sinkhole herein refers primarily to collapse sinkholes, that is, the abrupt or progressive downward failure of the ground surface into subsurface voids, as distinct from solutional closed depressions of purely karst origin. This paper synthesizes five decades (1976-2026) of documented sinkhole and ground subsidence records across the state, examining root causes, societal and environmental impacts, and remediation strategies employed in response to such hazards. The review shows that New Jersey’s hazard is governed by three dominant mechanisms: karst dissolution in carbonate …

A Field-Inspired Investigation Of Conduit Network Impacts On Spring Flow In Karst Aquifers, Jennifer Huang, Jannes Kordilla, Marco Dentz, John Barry, Christian Langevin, Peter Kang
Sinkhole Conference 2026
Effective management of karst aquifers necessitates accurate characterization of flow and transport. However, modeling these highly heterogeneous systems is challenging due to the complex partitioning of recharge between bedrock and the embedded conduit network. The properties of conduit networks impact flow and transport, but there has not been a systematic, quantitative study of how conduit network structure and geometry impact spring hydrographs in naturalistic field conditions. In this field-inspired modeling study, we attempt to identify key geometric and structural properties of conduit networks that control flow in karst aquifers and use these insights to constrain our understanding of a nitrate …

Characterization Of The Galena Karst Of East-Central Olmsted County, Minnesota, John D. Barry, Ronald C. Spong, Peter J. Hutchinson, Martin Larsen, Anthony C. Runkel
Sinkhole Conference 2026
The Galena Group is mostly composed of carbonate rock with subordinate beds of fine siliciclastics, mainly shale. In southeastern Minnesota, it is a source of water for domestic and agricultural use. Hydrologic and geochemical characterization of a Galena Group spring, Bear Spring, began in 1979. Recent springshed delineation through dye tracing and continuous level, temperature, and nitrate monitoring has shed light on the aquifer’s hydrologic response to precipitation, but the degree of karstification in the Galena was unclear. Current and planned future modeling require additional insight into the pervasiveness of fractures and conduits, and their properties. A suite of characterization …

Investigating Sediment Accumulation Dynamics Via Integration Of Gis And Remote Sensing Tools Along With Physical/Chemical Characteristics Of Sediments In Owl Cave, Highland County, Virginia, Dhanuska B. Wijesinghe, Spencer Schmidt
Sinkhole Conference 2026
The Valley region of Virginia, USA, features cave and karst systems. Variation in surface topography and vegetation within these systems significantly affects sediment accumulation in cave ecosystems. Remote sensing and GIS tools effectively analyze surface conditions, including vegetation cover and its influence on sediment buildup in caves. This study involved collecting high-resolution drone imagery, such as LiDAR, multispectral, and thermal data near Owl Cave in Highland County, VA, to understand the sediment accumulation process inside the cave system. High-resolution digital elevation models (DEMs) were created from LiDAR point clouds, and vegetation indices like Normalized Difference Vegetation Index (NDVI) were calculated …

Cover Collapse Sinkholes In Stormwater Infrastructure In The Urban Karst Of Bowling Green, Kentucky: Occurrence, Mitigation, And Prevention, Nick Lawhon P.G., C.F.M.
Cover Collapse Sinkholes In Stormwater Infrastructure In The Urban Karst Of Bowling Green, Kentucky: Occurrence, Mitigation, And Prevention, Nick Lawhon P.G., C.F.M.
Sinkhole Conference 2026
Cover collapse sinkholes are an extremely common geohazard in karst terrains. These features, formed by concentrated flows of water entering the subsurface through discrete points in the epikarst, are particularly common in stormwater infrastructure in Bowling Green, KY. There are currently 787 known stormwater basins and hundreds of miles of stormwater conveyances in this fast-developing city, all of which concentrate stormwater flows over the naturally sinkhole-prone karst system. This paper reports on the occurrence of cover collapse sinkholes in stormwater infrastructure, particularly retention and detention basins, from inspections over the past 7 years and records from City-managed sinkhole repair projects, …
Biogeomechanics Of Eicp Reinforcement Of Karstified Rock Masses, Mary C. Ngoma, Oladoyin Kolawole
Biogeomechanics Of Eicp Reinforcement Of Karstified Rock Masses, Mary C. Ngoma, Oladoyin Kolawole
Sinkhole Conference 2026
Sinkholes are among the most significant karst-related hazards, arising from the dissolution of soluble rock and subsequent collapse of overlying geomaterials, thereby compromising rock mass stability and underground infrastructure. Conventional sinkhole remediation approaches often rely on cement-based grouting to prevent failure; however, the associated environmental impacts underscore the need for eco-friendly and sustainable alternatives such as biocementation. While biocementation has been a widely applied technique in reinforcing soils and cemented structures, the potential of biocemented hybrid soil-embedded karstified rock systems remains unexplored. To address sinkhole-related post-hazard remediation, this work investigates the potential of biocementation as a sustainable reinforcement strategy for …

Sinkhole Conference 2026
Karst features pose significant risks to infrastructure and land use, from reducing tillable acreage to causing catastrophic failures in wastewater lagoons. This study analyzes the stratigraphic and spatial distribution of karst features in southeastern Minnesota to better understand their geologic controls. By seamlessly merging raster surfaces of Paleozoic bedrock units and intersecting them with regional karst datasets in a GIS framework, we found that over 95 percent of mapped sinkholes occur where unconsolidated sediment overlying bedrock is 15 meters or less. Furthermore, 81 percent of sinkholes are concentrated in just six of the 21 mappable bedrock units, each of which …
Hasparos Embayment – An Example Of Intrastratal Hypogenic Speleogenesis, Peter Hutchinson
Hasparos Embayment – An Example Of Intrastratal Hypogenic Speleogenesis, Peter Hutchinson
Sinkhole Conference 2026
The Hasparos Embayment contains Neogene-aged deposits that overlie the Permian-aged San Andres Formation. The Hasparos Embayment consists of thousands of subsidence sinkholes, concentrated in two tracts that are overlain with deposits provisionally considered to be part of the Ogallala Formation. The two Ogallala-covered karst fields are divided north and south by the Hasparos Canyon. The northern karst field includes 12,400 hectares, whereas the southern tract includes 6,900 hectares. Intrastratal karst is a form of hypogene speleogenesis, in which karst develops in rocks buried by younger deposits after deposition of the younger rocks. Thus during the temperate, late Pleistocene epoch, Lake …
Constraining The Groundwater Pathways Driving Cave Formation In The Water Sinks Area In Highland County, Virginia, Usa Using Electrical Resistivity Imaging, Shamsuddin Ahmed, R Shane Mcgary
Constraining The Groundwater Pathways Driving Cave Formation In The Water Sinks Area In Highland County, Virginia, Usa Using Electrical Resistivity Imaging, Shamsuddin Ahmed, R Shane Mcgary
Sinkhole Conference 2026
Speleogenesis in carbonate bedrock occurs when water, acidified by CO2 , dissolves calcium carbonate (CaCO3) in rocks to form voids and dissolutional conduits. The near surface geology of the Water Sinks area is dominated by Silurian–Devonian limestones, accommodating numerous karst features including sinkholes, caves, and springs. Groundwater flow and cave development in the area is thought to be guided primarily by geologic structure (folds, bedding, and joints) and low-permeability layers. In this study, we use electrical resistivity methods to detect and characterize conduits and water flow paths in the subsurface. We collect dipole-dipole and Schlumberger array data along seven transects …

Brine-Enhanced Hypogenic Speleogenesis And Concentrated Karst Development In The Burton Flats, Eddy County, New Mexico, Dave Decker, Garrett Jorgensen Olague, Michael Jones, Ryan Palmer
Sinkhole Conference 2026
The Burton Flats, a 259-km² gypsum-dominated outcrop of the Permian Rustler Formation 26 km northeast of Carlsbad, New Mexico, contains more than 3,500 documented karst features — an anomalously high density relative to surrounding areas of equivalent lithology. The proposed explanation is a two-step brine-enhanced dissolution mechanism driven by the spatial intersection of three factors: the eastward-dipping Rustler Formation outcrop, the underlying Capitan Aquifer, and the intervening Permian Salado Formation. Fresh Capitan water dissolves Salado halite, generating an NaCl-enriched brine up to three times more aggressive toward gypsum dissolution than fresh water; this brine ascends into the Rustler Formation along …
Service Robots With Low Anthropomorphism In Restaurants: Consumer Reactions And Implications, Ferhat Eren, Volkan Genc
Service Robots With Low Anthropomorphism In Restaurants: Consumer Reactions And Implications, Ferhat Eren, Volkan Genc
Journal of Global Hospitality and Tourism
This study investigates consumer responses to low-anthropomorphic service robots in restaurant front of-house roles using the AIDUA (Artificially Intelligent Device Use Acceptance). Data from 1,268 participants were analysed using PLS-SEM. The results revealed that social impact and anthropomorphism significantly influenced both performance and effort expectancy, while hedonic motivation influenced only performance expectancy. Performance expectancy strongly influenced emotions, which in turn significantly influenced both the willingness to use service robots and objections to their use. However, effort expectancy did not significantly influence emotions. The findings validate the AIDUA model in this context and offer practical insights for robot design and implementation.

Cognitive Resilience At The Edge: Hyperdimensional Computing Versus Deep Learning For Hardware-Degraded Rf Classification, Adrian B. Cisneros, Jeong Yang
Military Cyber Affairs
Autonomous Collaborative Combat Aircraft (CCA) operating in contested electromagnetic environments must classify Radio Frequency (RF) signals on edge silicon that degrades over the mission lifetime due to thermal stress, radiation, and manufacturing variation. Deep neural networks dominate RF classification on pristine hardware, but their weights are precise and interdependent, causing catastrophic accuracy collapse as the underlying chip ages. We investigate whether Hyperdimensional Computing (HDC), a brain-inspired paradigm that distributes information across thousands of dimensions, can provide a reliability floor where Deep Learning fails. Using the RadioML 2016.10A dataset filtered to five digital modulations relevant to drone command-and-control links, we trained …
