Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Toxic fumes emitted during the construction and maintenance of hot-mix asphalt mixtures represent a significant challenge for both the environment and construction workers. To reduce the generation of these toxic fumes, nano-sepiolite (NSEP, a natural mineral) powder was incorporated into base asphalt (BA), styrene-butadiene-styrene (SBS) -modified asphalt (SBSA), and crumb rubber-modified asphalt (CRA) to formulate sepiolite-modified asphalt binders. The rheological properties of these NSEP-modified asphalts were evaluated using dynamic shear rheometer (DSR) and bending beam rheometer (BBR) tests. Subsequently, smoke density tests and gas chromatography-mass spectrometry (GC-MS) were utilized to analyze the quantity and composition of the volatile organic compounds …

Material Point Method Simulation Of Soil Landslide Considering Interface Friction Effect, Zuo Zhipeng, Hu Shengliang, Li Maowen, Tong Chenxi, Li Haichao

Journal of China & Foreign Highway

During the high-speed and long-runout sliding failure process of large landslides, severe friction and heat generation in the sliding zone induce an interface friction effect between the debris flow and the bedrock, influencing the final accumulation morphology of the landslide. In this paper, a two-dimensional landslide model of the Yangbaodi landslide in Shenzhen was established using the material point method. A contact algorithm was introduced through a multi-background grid method to conduct numerical simulations on the initiation, sliding, and accumulation processes of the landslide. The results show that after initiation, the landslide moves over a long distance in a flow-like …

Study On Calculation Method For Incremental Launching Based On Nonlinear Analysis, Mo Shanfeng, Huang Cailiang, Qin Hui

Journal of China & Foreign Highway

In view of the shortcomings of traditional incremental launching calculation methods and the assembly construction control of incremental launching beams, an incremental launching calculation method based on nonlinear analysis was proposed in this paper. This method could truly simulate the running state where the incremental launching pier remains stationary, and the beam moves forward. The assembly alignment of all segments of the beam and the real alignment of the beam under specified working conditions could be directly output. The prefabricated alignment of the main beam (i.e., unstressed alignment) did not need to be consistent with the slide alignment. When the …

Postpartum Spontaneous Coronary Artery Dissection Complicated By Ventricular Fibrillation: A Case Report, Han Wei Zheng, Ariana Rucker, Kelsey Van Housen, Patrick Faherty

Department of Emergency Medicine Faculty Papers

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is an uncommon but increasingly recognized cause of acute coronary syndrome (ACS), particularly in young women without traditional cardiovascular risk factors. Although SCAD frequently presents as myocardial infarction, life-threatening arrhythmic complications such as cardiac arrest remain rare and may complicate timely diagnosis and management. Pregnancy-associated SCAD is associated with increased clinical severity and a higher risk of complications. This case is notable for the occurrence of ventricular fibrillation arrest, as well as the coexistence of SCAD with features of stress-induced cardiomyopathy.

CASE PRESENTATION: A 33-year-old African American female, 9 days postpartum following an uncomplicated …

From Pathology To Ecology: Rethinking Student Well-Being Through Consciousness-Centered Education, Molly Beauregard

Journal of Conscious Evolution

This article revisits a five-year mixed-methods study conducted from 2012 to 2018, involving 207 student participants (n = 207), of an undergraduate sociology course—Consciousness, Creativity, and Identity—that integrated group meditation and mindfulness into a standard curriculum. Earlier analyses interpreted positive outcomes primarily as reductions in stress and improvements in attention among students. This paper reconsiders that interpretation, arguing that such a framing risks locating dysfunction within students rather than the social and cultural environments they inhabit.

Drawing on an ecological perspective, the study reexamines survey, reflection, and interview data documenting changes, not only in affect and attention, …

USF Tampa Graduate Theses and Dissertations

Universities currently face a growing public health concern regarding college students’ mental health and well-being (Hobbs et al., 2022; Sheldon et al., 2021). Given this, research has explored experiences that are advantageous for students’ overall well-being, including courses on positive psychology and service-learning experiences that may promote flourishing (Hobbs et al., 2022; Maples et al., 2022). Service-learning is also well situated to support undergraduate career development (Collison & Eck, 2022). Kranzler et al. (2011) described how the pedagogical approach of service-learning aligns well with positive psychology, leading them to implement a positive psychology service-learning course. However, to date, no study …

"Does The Penis Lie?": Truth, Sexuality, And Psychocarceral Power, Erin Mcqueary

USF Tampa Graduate Theses and Dissertations

This thesis critically examines the use of penile plethysmography (PPG), or phallometry, in the treatment and management of sex offenders in the late-twentieth century. Using the Florida Mental Health Institute’s 1986-1989 sex offender treatment program as a case study, it asks how phallometry came to be understood as an objective method for uncovering otherwise hidden sexual truths. Instead of focusing only on its appearance and development throughout the second half of the twentieth century, this thesis draws on the work of Michel Foucault to situate phallometric science within a broader history of sexuality and biopower. In doing so, it argues …

Review And Development Of An Explicit Machine Learning Model For Pollutant Gas Solubility In Ionic Liquids As Green Solvents, Amir Dashti, Farid Amirkhani, Mojtaba Raji, John L. Zhou, Ali Altaee, Ali Braytee, Brett Turner, Hossein Ali Khonakdar, Amir Razmjou

Research outputs 2022 to 2026

The increasing release of greenhouse gases (GHGs) like CO₂, CH₄, N₂O, and industrial contaminants (indirect GHGs) such as SO₂ and H₂S has prompted significant global worries due to their role in climate change, air pollution, and harm to the environment. Ionic liquids (ILs) as green solvents have emerged as promising alternatives to traditional solvents because of their minimal volatility, high thermal stability, and adjustable physicochemical characteristics. Yet, limited gas solubility data in ILs is hindering their applications in carbon capture and air pollution control. Machine learning (ML) is a powerful tool for modeling and simulating the solubility of polluting gases …

Translating Science Into Evidence-Based Policy For The Protection And Restoration Of Essential Fish Habitat, Olivier Le Pape, Benjamin J. Ciotti, Karen E. Van De Wolfshaar, Rochelle D. Seitz, Julia Friese, David Eggleston, Elliot J. Brown, Rachel M. Turnbull, Filipe Martinho, Adam Waugh, Francisco E. Werner, Kenneth A. Rose

School of Biological and Marine Sciences

Coastal and estuarine ecosystems are vital as essential fish habitat (EFH). Given accelerating climate- and human-driven environmental change, conserving these habitats is increasingly urgent to ensure the sustainability of marine populations and their associated fisheries. This paper examines how scientific knowledge is being used to support management of EFH in the USA, Europe, and elsewhere. We find that while scientific knowledge to identify and quantify important habitats has rapidly increased, the transfer of this knowledge to management practice has been limited and slow, resulting in important habitats being vulnerable to degradation. Through an international review of EFH concepts and their …

K4) Unesco Intangible Cultural Heritage Inscription: End Of The Road Or A New Beginning?, Michał Duda, Bogdan Włodarczyk, Marzena Makowska-Iskierka

International Religious Tourism and Pilgrimage Conferences

The aim of paper is to examine the changes triggered by the inscription of religious traditions on intangible cultural heritage lists - the national level and at the UNESCO Intangible Cultural Heritage List. Such inscriptions generate transformations observable at heritage sites, among communities safeguarding these traditions, and in the behaviours of visitors - phenomena referred to as the “UNESCO effect.” These changes often extend beyond individual sites, inspiring other communities and heritage bearers to seek heritage recognition.

The paper focuses on religious cultural heritage associated with the tradition of creating floral carpets for the Feast of Corpus Christi in Spycimierz, …

K1) Negotiating The Sacred: Religious Sensitivities Within Contemporary Tourism Practices, Polyxeni G. Moira Dr

International Religious Tourism and Pilgrimage Conferences

This study critically analyses ways of managing religious sensitivities in the contemporary tourism environment, focusing on the dynamic intersections between religious-cultural heritage, spirituality, and the visitor experience. Recognizing the diversity of tourist motivations—which range from traditional pilgrimage to purely cultural, historical, or educational pursuits—the study argues for the need for flexible models of governance. These models must strike a delicate balance between the accessibility of sacred sites and the necessary respect for their sanctity.

Through a thorough review of the interventions of international organizations (such as UNESCO, UNWTO, and ICCROM) and the analysis of good practice studies from various continents, …

L1) Religious Tourism In Islam: Between Spiritual Purpose And Sincere Intention, Tariq Elhadary, Razaq Raj

International Religious Tourism and Pilgrimage Conferences

This study explores religious tourism in Islam through the interrelated concepts of spiritual purpose and sincere intention. It argues that the Islamic understanding of religious experience extends beyond physical travel or the visitation of sacred sites, grounding its value in the inner dimension of faith. Islam prioritizes the essence of actions over their outward form, establishing conviction of the heart before verbal affirmation and physical practice. Accordingly, intention serves as the primary criterion for assessing the validity, acceptance, and spiritual completeness of deeds. Religious journeys such as Hajj, Umrah, and visits to holy sites therefore attain their authentic significance when …

K3) From Sacred Landscape To Pilgrimage Environment: The Case Of Monte San Giorgio And Mendrisio, Lorenzo Cantoni, Adine Gavazzi

International Religious Tourism and Pilgrimage Conferences

Across Europe, numerous historic pilgrimage landscapes no longer function as dominant religious destinations, yet devotional practices persist in fragmented, latent, or reinterpreted forms. Pilgrimage however appears to be undergoing a process of transformation within postsecular communities, where spiritual meaning coexists with heritage tourism, community identity, and cultural landscape management. Building on religious tourism studies, pilgrimage is understood as mobility toward sacred sites as well as a ritual process embedded in tradition, motivation, and lived experience (Griffin & Raj 2017). Contemporary scholarship emphasises that pilgrimage preserve the experiential and relational practice linking people, landscape and belief systems, while fighting the tourist …

Why Not Pachucos? Mexican Americans, Hollywood, And The Impact Of Sleepy Lagoon In The 1940s And 1950s, Krystal Catalina Ledesma

Journal of 20th Century Media History

The unsolved murder of a young Mexican American on the outskirts of Los Angeles in 1942—commonly known as the Sleepy Lagoon Murder—came at a pivotal time in Mexican American history. The consequent arrests, unjust trial, and imprisonment of over one dozen young Mexican American men caused such a stir that Sleepy Lagoon is considered a precursor to the infamous Zoot Suit Riots of 1943. During the Sleepy Lagoon trial, impassioned leftists in Los Angeles created the Sleepy Lagoon Defense Committee (SLDC) to raise awareness about the crime and trial and to collect funds from supporters across the U.S., who ranged …

J1) Reorienting The Pilgrim-Tourist Dichotomy, Daniel H. Olsen

International Religious Tourism and Pilgrimage Conferences

Over the past decade, the pilgrim–tourist dichotomy, originally articulated by Smith (1992), has come under sustained scrutiny, particularly in light of postmodern critiques that problematize rigid dualisms and emphasize the fluidity of personal identity. Scholars have long debated the usefulness of this binary framework. On one hand, some have sought to refine the dichotomy by inserting additional categories along a spectrum, attempting to capture the nuances between pilgrims and tourists. On the other hand, many critics have dismissed the model’s analytical utility entirely, often without offering a concrete alternative to understand the distinctions between these two types of travelers.

This …

J2) Whose Sacredness? A Systematized Review Of Theoretical Grounding And Social Representation In Tourism Studies, Ana Maria Candell Saldarreaga, Silvia Aulet

International Religious Tourism and Pilgrimage Conferences

This paper presents a critical and systematized literature review of how sacred spaces and sites are conceptualized within tourism studies. Although research increasingly engages with religious, spiritual, heritage, and secular sites, the concept of 'sacredness' is frequently employed without explicit definition or consistent theoretical grounding, often leading to an analytical ambiguity between traditional devotion and contemporary heritage consumption. Consequently, the central question this study addresses is: In what ways is tourism scholarship conceptualizing sacrality, and what is being overlooked in the process. To address this, the study examines dominant disciplinary perspectives, the types of spaces analysed, and the positioning of …
