The Nature Of Human Trafficking Enterprises: Analysis Of U.S. And International Prosecutions--And The Path Forward, Jay Albanese Aug 2026

The Nature Of Human Trafficking Enterprises: Analysis Of U.S. And International Prosecutions--And The Path Forward, Jay Albanese

Dignity: A Journal of Analysis of Exploitation and Violence

The primary objective of this research is to develop a description and typology of the nature of serious cases of human trafficking and how traffickers, their victims, and consumers (the demand) overlap and interact across locations. This study examines known human trafficking enterprises for which sufficient evidence has been obtained to result in prosecution. These are also serious cases because US federal and international prosecutions result when the offenses are interstate or international in scope. Using a sample of US cases prosecuted over three calendar years (2021-2024), combined with an international sample of cases, an effort is made to develop …

Disrupting Transnational Human Trafficking Networks: A Practitioner's Perspective On Intelligence-Driven, Offender-Focused Strategies, Rochelle Keyhan Aug 2026

Disrupting Transnational Human Trafficking Networks: A Practitioner's Perspective On Intelligence-Driven, Offender-Focused Strategies, Rochelle Keyhan

Dignity: A Journal of Analysis of Exploitation and Violence

This article examines human trafficking through the lens of organized crime and explores how this perspective can be applied to contemporary trafficking cases in the United States. While trafficking is often prosecuted as an isolated criminal act, many incidents are linked to larger transnational and domestic organized crime networks. The discussion highlights the activities of notorious syndicates, including international cartels, street gangs, and well-funded networks of sex buyers, demonstrating how these entities exploit vulnerable populations for profit. Reframing human trafficking as a sector within organized crime shifts investigative and prosecutorial strategies away from victim-dependent models, which often require survivors to …


A Thickness-Invariant Origami Robot With Integrated Actuation And Multimodel Locomotion, Larry L. Howell, Davis Wing, Nathan Usevitch, Sam Bridge, William Bowler Aug 2026

A Thickness-Invariant Origami Robot With Integrated Actuation And Multimodel Locomotion, Larry L. Howell, Davis Wing, Nathan Usevitch, Sam Bridge, William Bowler

Faculty Publications

ABSTRACT Origami robots possess the potential for advanced reconfigurability in various contexts and environments. This paper describes and demonstrates the function of an origami robot following a thickness-invariant version of the Yoshimura tessellation. This thickness-invariance allows for the simple folding pattern to be expanded vertically, allowing all robotics components to be housed within the panels of the robot without impacting the functional relationships between folds of the pattern, or requiring other, more complex forms of thickness accommodation. The mathematics and engineering to create such a robot are presented to enable the use of these techniques in creating other origami-based robots. …


Polyphenol Diet And Exercise As Neuroprotection From Effects Of Alzheimer's Disease, Michelle Morgan Aug 2026

Polyphenol Diet And Exercise As Neuroprotection From Effects Of Alzheimer's Disease, Michelle Morgan

Loma Linda University Electronic Theses, Dissertations & Projects

Healthy non-pharmacological lifestyle factors, such as regular physical exercise and a dietary supplementation, have been shown to significantly improve cognitive outcomes over time compared to a more sedentary lifestyle and poor diet. Furthermore, exercise may serve as a potential protective factor in attenuating the effects associated with cognitive decline that are characteristic of neurodegenerative disorders, such as Alzheimer's disease (AD). Further, evidence indicates that certain diet interventions can also attenuate the effects of neurodegeneration and positively impact longevity. Supplementation of polyphenols, such as ellagic acid (EA), which are abundant in pomegranate juice, may help provide neuroprotective benefits and elicit a …


Comparison Of Lower-Extremity Coordination Patterns During Countermovement Jumps Between Dancers And Nondancers, Danielle Joseph Aug 2026

Comparison Of Lower-Extremity Coordination Patterns During Countermovement Jumps Between Dancers And Nondancers, Danielle Joseph

Honors Theses

Jumping is a skill essential to several different sports, including dance. For athletes in jump-dominant sports, jump strategies can vary with differences in task demands while jump performances are similar. The countermovement jump (CMJ) has been utilized to analyze jumps because of their reliable indications of power and neuromuscular function. Methods of describing jump strategies using CMJ, such as force plate metrics, vector coding analysis, and coordination phases, have been used to describe the jumps of athletes in jump dominant sports such as basketball and volleyball. However, less jump strategy research has been done on dancers, especially to describe the …

Traumatic knee injury leads to posttraumatic osteoarthritis (PTOA) and significant skeletal muscle weakness, resulting in chronic disability. The current standard of care frequently fails to prevent musculoskeletal dysfunction, underscoring the need to identify therapeutic mechanisms of PTOA. Using an established preclinical anterior cruciate ligament (ACL) transection model of PTOA and leveraging an innovative SPiDER-senescence-associated β-galactosidase stain to discern senescent cells, we investigated cellular senescence at single-cell resolution and identified anti-inflammatory macrophages as a predominant contributor to the senescent cell burden in both muscle and knee joint after injury. Clearance of senescent cells using the senolytic dasatinib and quercetin (D + …

Professor Greenfeld’S Last Class: Notes For Online Lectures On “The Science Of Humanity,” Delivered To Students And Scholars Primarily From India, July 2025, Liah Greenfeld

Comparative Civilizations Review

The question for this class is: What is humanity?

We all believe we all know what it is, don’t we? After all, there is hardly any subject more important for us, a question on the answer to which other subjects depend — political, social, economic. Answers to questions such as: what are human economic needs and desires; what political structures are optimal for humans; is democracy, for instance, a universal human desire; should politics in every nation be democratic, or, perhaps, authoritarian governments are better; is freedom a natural need, does it make life better, does equality?

A Stabilized Weighted Interior Penalty Method For Thermal Convection Model In Heterogeneous Porous Media, Yuanyuan Hou, Qianqian Ding, Xiaoming He, Yanping Lin Aug 2026

A Stabilized Weighted Interior Penalty Method For Thermal Convection Model In Heterogeneous Porous Media, Yuanyuan Hou, Qianqian Ding, Xiaoming He, Yanping Lin

Mathematics and Statistics Faculty Research & Creative Works

In this article, we propose and analyze a stabilized weighted interior penalty method for solving the thermal convection problems in heterogeneous porous media. We first transform the thermal convection model into the pressure primal form with homogeneous Neumann boundary condition and develop a symmetric weighted interior penalty method to handle the discontinuous Darcy number and automatically adjust the penalty coefficient corresponding to the varying permeability. Then we recover the velocity by a stabilized method and incorporate it into the energy equation to obtain the temperature. The stability and convergence rates of the numerical solutions are rigorously proved and verified by …

The True Scope Of Trusting Your Gut: A Study Into The Enteric Nervous System And The Relationship Between The Gut-Brain Axis And The Mind, Bryan Pham Aug 2026

The True Scope Of Trusting Your Gut: A Study Into The Enteric Nervous System And The Relationship Between The Gut-Brain Axis And The Mind, Bryan Pham

Theses & ETDs

Since the early days of medicine, the “gut” had been associated as a seat of emotions and intuition, but as modern science marched forward, the brain itself was given complete dominion over mental health. But thanks to research into the enteric nervous system (ENS), which innervates the digestive tract and bilaterally communicates with the brain as a secondary function, we now know that, in a sense, the gut does indeed have a substantial impact on mental health outside of its primary functions. This profound discovery could potentially cause a massive rewrite for decades of modern neuroscience-based medicine. Overall, the study …

All pyrolysis experiments were performed using a Pyroprobe 5200 coupled with GC-MS/FID, while catalyst loading, hydrogen pressure, …


Development And Validation Of A Multidimensional Measure Of Role Ambiguity: Integrating Nlp-Based Factor Analytic Techniques With Traditional Psychometrics, Md Allama Ikbal Sijan Aug 2026

Development And Validation Of A Multidimensional Measure Of Role Ambiguity: Integrating Nlp-Based Factor Analytic Techniques With Traditional Psychometrics, Md Allama Ikbal Sijan

Theses, Dissertations and Culminating Projects

This dissertation developed and validated the Multidimensional Role Ambiguity Scale (MRAS), a measure that separates role ambiguity into five subdimensions: goal/expectation/responsibility ambiguity, process ambiguity, priority ambiguity, behavior ambiguity, and performance criterion ambiguity. Although role ambiguity is one of the most studied role stressors in organizational research, it has been measured largely as a single global score, a practice that masks differences among its facets and may explain the inconsistent criterion relationships reported in prior work. Scale development followed the three-step framework of Singh and Rhoads (1991). Thirty items were generated from working definitions grounded in role theory, and fifteen research …


Temperature And Salinity Effects On The Physiology Of Bullfrog Tadpoles (Lithobates Catesbeianus) From A Suburban Temperate Wetland, Angela Brown Aug 2026

Temperature And Salinity Effects On The Physiology Of Bullfrog Tadpoles (Lithobates Catesbeianus) From A Suburban Temperate Wetland, Angela Brown

Theses, Dissertations and Culminating Projects

One of the most robust amphibians is the American Bullfrog, Lithobates catesbeianus, which is a widespread species that is invasive worldwide, and is broadly tolerant of a range of environmental conditions. Despite this tolerance, survival and performance of adult L. catesbeianus can be negatively affected by increasing temperatures and salinity resulting from anthropogenic impacts, such as climate change and road salts. This study focuses on the effects of acute salinity exposure (mimicking road salt influx into a pond) on L. catesbeianus tadpoles at different larval stages. Increased salinity was predicted to negatively affect two physiological performance measures. Critical maximum temperature …


A Comprehensive Study And Performance Optimization Of Shared Virtual Memory, Bennett Cooper Aug 2026

A Comprehensive Study And Performance Optimization Of Shared Virtual Memory, Bennett Cooper

All Dissertations

High performance computing (HPC) is dominated by heterogeneous systems that mainly derive performance from GPU accelerators. A majority of HPC applications have gravitated towards GPUs, which require explicit programming. Historically, programming explicitly to take advantage of GPUs has proven a significant barrier in fully utilizing GPU acceleration. Unified Memory (UM) is a technology designed to lower the barrier of entry to GPU programming by merging all memory domains of a system. While UM provides easier access to the capabilities of heterogeneous systems, the performance cost of UM greatly detracts from the benefit. Additionally, UM is implemented on a vendor-by-vendor basis …


Exploring Optimal Indoor Environmental And Spatial Conditions In Virtual Reality: Implications For Human Experience And Productivity, Seonghyuk Son Aug 2026

Exploring Optimal Indoor Environmental And Spatial Conditions In Virtual Reality: Implications For Human Experience And Productivity, Seonghyuk Son

All Dissertations

This dissertation investigates how indoor environmental and spatial design conditions influence human experience and productivity, focusing on thermal conditions, lighting conditions, and spatial configuration. Because people spend most of their time indoors, environmental design plays an important role in comfort, emotional well-being, and cognitive functioning. Although previous studies have shown that temperature, lighting, and architectural features influence human responses, many have examined these variables separately. In addition, relatively few studies have integrated perceptual, emotional, cognitive, and physiological outcomes within a single framework.

Study 1 examined the combined effects of indoor temperature, lighting intensity, and correlated color temperature on cognitive performance …


Explaining The Relationship Between Trust And Dependence: The Unexplored Interactive Effect Of Workload And Individual Differences In Cognitive Abilities, Connie Ku Aug 2026

Explaining The Relationship Between Trust And Dependence: The Unexplored Interactive Effect Of Workload And Individual Differences In Cognitive Abilities, Connie Ku

All Dissertations

Trust is often treated as a key driver of automation use, with the assumption that higher trust leads to greater dependence. Yet findings have been inconsistent, with trust-dependence correlations ranging from negative to positive, and some studies finding no relationship at all. One factor that may explain this inconsistency is mental workload, which has received little attention as a moderator. This research examined whether workload moderates the trust-dependence relationship, and whether attention control, working memory, and fluid intelligence further shape this moderation.

Study 1 used a web-based AI chatbot quiz to test whether workload moderated the trust-dependence relationship. Trust was …
