Digitalverse And The African Narratives: Ai As A New Platform For African Cultural Preservation, Mudasiru Babatunde Sulaiman Mr, Tajudeen Salaudeen Oct 2026

Digitalverse And The African Narratives: Ai As A New Platform For African Cultural Preservation, Mudasiru Babatunde Sulaiman Mr, Tajudeen Salaudeen

Tête à Tête: Journal of Francophone Studies

Abstract

This article delves into the concept of digital universe as a transforming digital system for the preservation of African culture, with a target on the unique role of artificial intelligence (AI) as a means of storytelling and cultural continuity. For long, there have been problems of availability of sustainable digital infrastructure where African storytelling can be preserved. This study therefore examines the intersection of AI and African storytelling through emerging digital projects, virtual storytelling spaces, and tools that digitize and translate African languages and oral traditions. It argues that AI not only expands the reach of African cultural narratives, …


Cultural And Social Inclusion In Sexe Et Mensonges: La Vie Sexuelle Au Maroc By Leïla Slimani: A Critical Perspective, Juliet N. Elikwu Dr. Oct 2026

Cultural And Social Inclusion In Sexe Et Mensonges: La Vie Sexuelle Au Maroc By Leïla Slimani: A Critical Perspective, Juliet N. Elikwu Dr.

Tête à Tête: Journal of Francophone Studies

Several published studies on Leïla Slimani's Sexe et Mensonges: La Vie sexuelle au Maroc have extensively examined the themes of sexual taboos and the challenges facing women in Moroccan society. But, limited attention has been given to her portrayal of cultural and social inclusion through the testimonies and narratives of marginalized women in academic discourse. This study seeks to analyze the dynamics of inclusion and exclusion within the framework of cultural norms and patriarchal structures depicted in the work. The study draws on a qualitative methodology centered on close textual analysis. The theoretical framework integrates Michel Foucault’s concepts of power …

Nothing Is As It Should Be: Estrangement, Threshold-Crossings, And Cosmic Struggle In David Lynch’S Blue Velvet And Lost Highway, Susanne Wigorts Yngvesson Oct 2026

Nothing Is As It Should Be: Estrangement, Threshold-Crossings, And Cosmic Struggle In David Lynch’S Blue Velvet And Lost Highway, Susanne Wigorts Yngvesson

Journal of Religion & Film

This article examines estrangement as a structuring existential and aesthetic principle in David Lynch’s Blue Velvet (1986) and Lost Highway (1997). Through close, plot-attentive readings intended to remain accessible to readers unfamiliar with Lynch, it argues that the films stage three interlocking dynamics: becoming a stranger to oneself, the fracturing of the ‘ground’ of ordinary existence, and life as a cosmic struggle in which human agency is partial and contested. Paul Tillich’s The Courage to Be provides the main theological–philosophical lens, clarifying how anxiety, non-being and courage shape scenes of desire, violence and transformation. Film-theoretical work on thresholds and cinematic …


No Place For Us: The Scapegoat Mechanism In The Early Genealogy Of The Outlaw Road Movie, Luke Smith Oct 2026

No Place For Us: The Scapegoat Mechanism In The Early Genealogy Of The Outlaw Road Movie, Luke Smith

Journal of Religion & Film

This essay applies René Girard’s scapegoat mechanism to an early genealogy of the outlaw-couple-on-the-run narrative and of the outlaw road movie more broadly. Through readings of You Only Live Once (1937), They Live by Night (1948), Gun Crazy (1950), and Bonnie and Clyde (1967), it argues that scapegoating in these films operates as a process rather than a single final act: the outlaw couple is first marked and excluded from ordinary goods such as work, respectability, and domestic space, then publicly blamed as a cause of disorder, then amplified through mythmaking, circulation, and repetition until finally sacrificed in a closing …


Misread Before Being Known: Race, Religion, And Institutional Non-Inquiry In Abrogation, Franklin Livingston Oct 2026

Misread Before Being Known: Race, Religion, And Institutional Non-Inquiry In Abrogation, Franklin Livingston

Journal of Religion & Film

Institutions often arrive at certainty before they arrive at knowledge. This article names that mechanism institutional non-inquiry — the organizational habit through which visual and cultural assumptions substitute for direct verification, allowing identity classifications to solidify before the subject meaningfully enters the encounter. Unlike prejudice, racialization, or established theories of pre-reflexive social perception, institutional non-inquiry isolates the organizational encounter itself as the specific procedural moment at which collective interpretive habits make inquiry feel unnecessary. Examining Abrogation (2024), a micro-budget American independent feature following Daud Khan, a Brown Pakistani-American infectious disease specialist whose movement through evangelical, civic, and federal institutions repeatedly …


Moving On: Purgatorial Seriality And Unanswered Prayer In Lost’S “Ab Aeterno”, Christian Wilken Oct 2026

Moving On: Purgatorial Seriality And Unanswered Prayer In Lost’S “Ab Aeterno”, Christian Wilken

Journal of Religion & Film

“Ab Aeterno” (Lost, 6.09) distills the series’ religious logic with unusual explicitness by staging theodicy not as doctrine but as narrative procedure. This article argues that the episode converts Catholic sacramental form (confession, absolution, and penitential address) into a serial ethics of endurance in which closure is structurally deferred. Richard Alpert’s confession establishes a subject who seeks an authorized word that would stabilize suffering, yet the priest’s refusal (“I can’t”) installs a theology of unanswered prayer that becomes the template for Richard’s long durée of waiting. Jacob’s “cork” parable then supplies a katechontic justification of restraint: evil is not abolished …


Between Icon And State: Sergei Eisenstein's Ivan The Terrible, Milja Radovic Oct 2026

Between Icon And State: Sergei Eisenstein's Ivan The Terrible, Milja Radovic

Journal of Religion & Film

Remembering the 80th anniversary of Sergei Eisenstein’s film Иван Грозный (Ivan the Terrible, 1944/1945), it is crucial to re-examine Eisenstein’s work, including his last film that became an unintentional ‘testament’ to cinema. Eisenstein’s mastery has been pivotal for understanding cinema and film language, the way this language operates, constructs and deconstructs and communicates historical realities. This paper focuses on a film that was made in two parts, Part I in 1944 and part II in 1945, to investigate Eisenstein’s approach to the subject of history, nation and religion. The research considers how this master of cinema contemplated intricate ideas and …


Piercing The Veil In Sinners: Theological Insights From The Juke Joint, Antonio D. Sison Cpps Oct 2026

Piercing The Veil In Sinners: Theological Insights From The Juke Joint, Antonio D. Sison Cpps

Journal of Religion & Film

Celebrated as a critical and commercial success, Ryan Coogler’s genre-defying opus Sinners has also been considered as one of the most culturally significant films of 2025. It also promises to be one of the most theologically resonant films of the year. This is evinced not only in its thematic and literary bases but, importantly, in its very audiovisual language and grammar, its stylistic strategies qua film. As reasoned in this essay, Coogler’s film is a rich locus theologicus, a nexus for theological discovery and insight.Sinners kindles the hermeneutical impulse to dialogue with African American/Pan-Africa theologies exemplified by the …


Affirmative Transcendence: The Ethics Of Mazu And The Internal Expansion Of The Confucian Moral Imagination, Yu Pei Oct 2026

Affirmative Transcendence: The Ethics Of Mazu And The Internal Expansion Of The Confucian Moral Imagination, Yu Pei

Journal of Religion & Film

This paper proposes and defends the concept of affirmative transcendence through a systematic analysis of the 2012 Chinese television drama Mazu (38 episodes, CCTV). Affirmative transcendence names a structure in which the protagonist achieves sacred status (shen 神) not by negating her human relationships but by maintaining them while exhibiting a mode of moral perception that exceeds the limits of role-based ethics. The paper argues that what is analytically distinctive about this structure is its internal character: the tradition is not rejected but exceeded, and the exceeding is accomplished through resources the tradition itself provides. The paper identifies two …


A Metaphorical Passage To God: Simone Weil And Robert Bresson, V. G. Voigt Hogg Phd Oct 2026

A Metaphorical Passage To God: Simone Weil And Robert Bresson, V. G. Voigt Hogg Phd

Journal of Religion & Film

VOIGT HOGG_Abstract (REVISED)_Journal of Religion & Film_30 April 2026

This article contrasts the metaphysical and religious philosopher Simone Weil’s concepts of attachment and detachment with auteur director Robert Bresson’s method of subtraction. It argues for a commonality in their philosophy and cinema, that guides the reader or viewer respectively, to perceive a metaphorical passage to God through the lived experience of suffering. The article considers by what means does Weil and Bresson share a mutual commitment to understanding the state of the soul in affliction, while also acknowledging an opposition in the interpretation of detachment in relation to suicide. The …

The Thai Journal of Veterinary Medicine

Sertoli cell tumors (SCTs) are sex cord–stromal tumors of the testis that are common in dogs but rare in boars. This study characterized the pathological features of an SCT in a boar and compared its immunohistochemical profile with that of canine SCTs. Testicular tissues from boars (SCT, n = 1; normal testes, n = 2) and dogs (SCT, n = 3; normal testes, n = 5) were evaluated by histopathology and immunohistochemistry for proliferating cell nuclear antigen (PCNA), vimentin, and cytokeratin. Gross examination revealed a solitary, well-circumscribed nodule in the left testis of the boar, accompanied by severe bilateral testicular …


Attention-Enhanced Multimodal Fusion Of Elevation And Aerial Imagery For Sinkhole Segmentation, Junfeng Zhu, Desireé Cunningham, Nathan Jacobs Oct 2026

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 …


Statewide Sinkhole Susceptibility Mapping In Florida Using Explainable Geoai, Osama M. Altarawneh, Weiwei Zhan, Clint Kromhout Oct 2026

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 Oct 2026

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 Oct 2026

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 …

Karst Sinkholes And Civil Engineering: Overview Of Characterization And Treatment Options From A Geophysical And Geotechnical Viewpoint, Mia Painter, Stephen Welsh

Sinkhole Conference 2026

Sinkholes pose a significant geohazard to civil engineering infrastructure in regions underlain by carbonate karst terrain. Selecting an appropriate stabilization method requires balancing site conditions, infrastructure risk, environmental considerations, and cost, all of which depend on a thorough understanding of the planned or existing infrastructure and subsurface conditions. This paper provides an overview of common sinkhole characterization and stabilization methods used in the Mid-Atlantic and Appalachian regions of the United States from both geotechnical and geophysical perspectives. The application of geophysical methods in conjunction with intrusive investigations is reviewed as a means of reducing subsurface uncertainty and refining treatment designs. …


Sinkhole Hazards, Risks, And Remediation: A Fifty-Year Case Study In New Jersey, Usa, Oladoyin Kolawole, Rita L. Sousa, Christina Comuso, Mohab Hussein Oct 2026

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 …


Creating A Karst Features Map Of A 7.5-Minute Quadrangle In Northern New Jersey, Zachary Schagrin Oct 2026

Creating A Karst Features Map Of A 7.5-Minute Quadrangle In Northern New Jersey, Zachary Schagrin

Sinkhole Conference 2026

Extensive areas of northern New Jersey are underlain by carbonate rocks, ranging from Proterozoic marbles to Paleozoic limestones and dolomites. These areas include large portions of Sussex and Warren Counties, as well as smaller areas within Hunterdon, Morris, Passaic, and Somerset Counties. As part of its efforts to map the geology of the state, the New Jersey Geological and Water Survey (NJGWS) has undertaken efforts to create karst features maps of quadrangles within this area—known as the Karst Susceptibility Project Area. Through field mapping, GIS analysis, and interpretation of past data collection, NJGWS began publishing these 1:24,000-scale maps in 2023. …


Remediating Groundwater In A Karst Terrane: Encouraging Results And Lessons Learned, Urvi Tulsiani, Jason M. Tillotson, Allison Nelan, Keith A. White Oct 2026

Remediating Groundwater In A Karst Terrane: Encouraging Results And Lessons Learned, Urvi Tulsiani, Jason M. Tillotson, Allison Nelan, Keith A. White

Sinkhole Conference 2026

Karst aquifers, characterized by a combination of multiple porosity types, discrete flow paths, and variable hydraulic conductivities, create a highly complex and heterogeneous environment that influences both the storage capacity and transport of contaminants in the subsurface. These complexities of karst aquifers present unique challenges for remediating contaminated groundwater. Pilot studies were performed at eight sites at Redstone Arsenal (RSA) in Huntsville, Alabama, to assess the viability of in situ injection-based remedies to treat groundwater impacted by chlorinated volatile organic compounds (CVOCs) and perchlorate in the epikarst, the uppermost, highly weathered rind of karst bedrock. The studies assessed effectiveness of …


Ongoing Dye Tracing Prompts Major Reevaluation Of Groundwater Divides For The Lost River Karst System, Bowling Green, Ky, Usa, Lee Anne Bledsoe, Chris G. Groves, Nick Lawhon Oct 2026

Ongoing Dye Tracing Prompts Major Reevaluation Of Groundwater Divides For The Lost River Karst System, Bowling Green, Ky, Usa, Lee Anne Bledsoe, Chris G. Groves, Nick Lawhon

Sinkhole Conference 2026

The Lost River Groundwater Basin located in south-central Kentucky may be one of the most thoroughly investigated karst basins in the US. Over the past 50 years, numerous studies have been conducted primarily due to the environmental challenges created by urban development on a well-developed sinkhole plain. The City of Bowling Green (pop. ~80,000) covers much of the basin but lies primarily in the northern, downstream reach nearest the main outlet of the system, the Lost River Rise. However, land use in the southern, up-gradient, portion of the basin is quickly changing from undeveloped and/or agriculture to industrial and residential. …


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 Oct 2026

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 …

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. Oct 2026

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, …
