Rehabilitation Sciences Faculty Publications

Background/Purpose: Fractal gait patterns have been shown to be modifiable, but the extent to which they are retained and transferred to new contexts is relatively unknown. This study aimed to close those gaps by enrolling participants (N = 23) in a seven-day fractal gait training program. Methods: Building on related work, the fractal gait training occurred on a treadmill over a 10-min period. Before and after the treadmill training, each participant walked for 10 min overground without the fractal stimulus used during training. The daily post-test was used to examine immediate retention and transfer of the fractal gait patterns from …

Lecture-Based Instruction On Salary Negotiation For Professional Athletic Training Students: An Educational Technique, Julie M. Cavallario, Thomas R. Campbell, Cailee E. Welch Bacon

Rehabilitation Sciences Faculty Publications

Context

Low salary is a frequently cited reason for attrition from the athletic training profession. Researchers have determined that athletic trainers (ATs) entering the first hiring process, usually newly credentialed graduates of professional athletic training programs (ATPs), are the least likely to negotiate, resulting in lowered earning potential across their careers. It is necessary to instruct athletic training students on the importance of salary negotiation before the completion of their professional preparation.

Objective

Describe a lecture-based approach to include salary negotiation content into ATPs.

Background

Employing constructivist learning theory, didactic lecture content with applicable strategies for salary negotiation is sufficient …

Joseph Of Egypt As A Model Of Gospel Living, Khumbulani D. Mdletshe Jan 2024

Joseph Of Egypt As A Model Of Gospel Living, Khumbulani D. Mdletshe

Religious Educator: Perspectives on the Restored Gospel

In Genesis 37–50, the narrative of Joseph of Egypt offers instructive lessons on the blessings that flow from persevering through trials while honoring covenant commitments with God. Joseph’s capacity to consistently and courageously apply eternal principles when facing abuse, temptation, injustice, and other challenges not only led to his personal success but also proved critical for those whom he served as a slave and prisoner and, once he was elevated to great power in Egypt, for the numerous subjects of Pharaoh’s kingdom during times of famine. This essay identifies and discusses the primary principles that guided Joseph’s efforts to accomplish …

Relational Grace The Reciprocal And Binding Covenant Of Charis, Brent J. Schmidt Jan 2024

Relational Grace The Reciprocal And Binding Covenant Of Charis, Brent J. Schmidt

Religious Educator: Perspectives on the Restored Gospel

In New Testament times, the concept of grace (Greek charis) was operative in relationships in which a person giving something of value to another could expect the recipient to provide service, thanks, or something else of much lesser value in return. When the Apostle Paul described Jesus Christ’s atoning sacrifice as a gift (charis), his ancient audiences understood that redemptive act as initiating a covenantal bond with expectations of devoted discipleship. Bible translators have never properly conveyed Paul’s message of active, obliging grace, an oversight that some scholars of the New Pauline Perspective are now demonstrating. During the Great Apostasy, …

Progress And The Taking Of Indigenous Land, Ezra Rosser Jan 2024

Progress And The Taking Of Indigenous Land, Ezra Rosser

Scholarly Articles in Law Reviews & Journals

The taking of Indigenous land in furtherance of other societal goals is so ubiquitous and so fundamental to the American project that sometimes acts of dispossession are not even recognized as such. This Article argues that the generally accepted understanding of Hawaii Housing Authority v. Midkiff, a key case of the American takings law canon, is wrong because it overlooks Native Hawaiian claims to the land taken. Hawai‘i’s Land Reform Act allowed tenants a right to purchase land over the objections of the owner of the underlying property and in Midkiff the U.S. Supreme Court said that states had the …


Digital Bank Holidays, Hilary J. Allen Jan 2024

Digital Bank Holidays, Hilary J. Allen

Scholarly Articles in Law Reviews & Journals

The March 2023 run on Silicon Valley Bank spurred renewed debate about how to structure deposit insurance to best eliminate future bank runs. This Article argues, however, that deposit insurance cannot be relied upon to eliminate all bank runs, especially if technological developments create potential new bank run triggers that deposit insurance may not be responsive to. We may be expecting too much of deposit insurance, and so it is worth considering other tools that might be useful in responding to future bank runs and broader banking panics. One such tool is the “bank holiday,” last deployed in the United …


Digital Rummaging, Andrew Guthrie Ferguson Jan 2024

Digital Rummaging, Andrew Guthrie Ferguson

Scholarly Articles in Law Reviews & Journals

The digital world encodes our lives with incriminating clues. How you travel, live, love, and shop are tracked through growing surveillance technologies. Police have recognized this reality and are actively exploiting new surveillance tools for investigative purposes.

The Fourth Amendment—the constitutional protection meant to limit police search powers—has not kept up with the privacy and security threats of these new digital technologies. Current doctrine has remained stymied by legal tests asking all the wrong questions about “reasonable expectations of privacy” and “trespass” searches. While the Supreme Court has acknowledged that “digital is different,” it has not yet provided a coherent …


Grasping The Third Rail: Restorative Justice And Violent Crime, Olwyn Conway Jan 2024

Grasping The Third Rail: Restorative Justice And Violent Crime, Olwyn Conway

Scholarly Articles in Law Reviews & Journals

Restorative justice is a means of responding to harm— including criminal offenses—through active accountability and repair, rather than through passive punishment and isolation. While restorative justice has demonstrated potential to meaningfully improve processes and outcomes for individuals and communities, the implementation of restorative justice programs to address crime—both within and alongside the American criminal system—has been slow, limited, and misplaced. Programs are often directed at low-level, nonviolent offenses that involve little if any cognizable harm. This approach creates two problems. One, it risks net-widening: bringing more citizens under criminal surveillance and carceral control for minor offenses—further diluting the constitutional and …


Why The Supreme Court Rejected The Prospect Theory Of Copyright Scope, Michael W. Carroll Jan 2024

Why The Supreme Court Rejected The Prospect Theory Of Copyright Scope, Michael W. Carroll

Scholarly Articles in Law Reviews & Journals

In Google LLC v. Oracle America, Inc. (“Google v. Oracle”), and again in Andy Warhol Found. for the Visual Arts, Inc. v. Goldsmith (“Warhol”), the parties and various amici presented the Court with a variety of arguments about the relationship between a copyright owner's right to make derivative works from a protected work and a user's right to make fair uses of that same work. At bottom, these arguments were about the proper, or even optimal, scope of copyright. This Essay argues that these arguments were instead grounded in a form of ““prospect theory” of copyright scope that would give …

How astrophysical systems translate the kinetic energy of bulk motion into the acceleration of particles to very high energies is a pressing question. SS 433 is a microquasar that emits TeV γ-rays indicating the presence of high-energy particles. A region of hard X-ray emission in the eastern lobe of SS 433 was recently identified as an acceleration site. We observed this region with the Imaging X-ray Polarimetry Explorer and measured a polarization degree in the range 38%–77%. The high polarization degree indicates the magnetic field has a well-ordered component if the X-rays are due to synchrotron emission. The polarization angle …

Voyager 1 and 2 data from the vicinity of the heliopause and very local interstellar medium are reexamined to better understand the confounding lack of rotation in the magnetic field (B-field) across the heliopause observed by both Voyagers, despite their very large spatial separations (>100 au). Using three estimates for the orientation of the B-field in the pristine interstellar medium and four models of the heliosphere, we calculate draped interstellar B-field orientations along the model heliopauses and compare those estimates to the Voyager observations. At both Voyagers, expected draped B-fields are inconsistent with the observed B-field orientations after the boundary …

Efficient High-Resolution Time Series Classification Via Attention Kronecker Decomposition, Aosong Feng, Jialin Chen, Juan Garza, Brooklyn Berry, Francisco Salazar, Yifeng Gao, Rex Ying, Leandros Tassiulas

Computer Science Faculty Publications

The high-resolution time series classification problem is essential due to the increasing availability of detailed temporal data in various domains. To tackle this challenge effectively, it is imperative that the state-of-theart attention model is scalable to accommodate the growing sequence lengths typically encountered in highresolution time series data, while also demonstrating robustness in handling the inherent noise prevalent in such datasets. To address this, we propose to hierarchically encode the long time series into multiple levels based on the interaction ranges. By capturing relationships at different levels, we can build more robust, expressive, and efficient models that are capable of …


Self Pre-Training With Topology- And Spatiality-Aware Masked Autoencoders For 3d Medical Image Segmentation, Pengfei Gu, Yejia Zhang, Huimin Li, Chaoli Wang, Danny Z. Chen Jan 2024

Self Pre-Training With Topology- And Spatiality-Aware Masked Autoencoders For 3d Medical Image Segmentation, Pengfei Gu, Yejia Zhang, Huimin Li, Chaoli Wang, Danny Z. Chen

Computer Science Faculty Publications

Masked Autoencoders (MAEs) have been shown to be effective in pre-training Vision Transformers (ViTs) for natural and medical image analysis problems. By reconstructing missing pixel/voxel information in visible patches, a ViT encoder can aggregate contextual information for downstream tasks. But, existing MAE pre-training methods, which were specifically developed with the ViT architecture, lack the ability to capture geometric shape and spatial information, which is critical for medical image segmentation tasks. In this paper, we propose a novel extension of known MAEs for self pre-training (i.e., models pre-trained on the same target dataset) for 3D medical image segmentation. (1) We propose …
