Rescaling: Change Agency And The Emerging Geography Of Economic Relationships, Markus Grillitsch, Björn Asheim, Nichola Lowe, Sophie Kelmenson, Lea Fünfschilling, Karl Johan Lundquist, Yahia Mahmoud, Mikhail Martynovich, Pauline Mattsson, Magnus Nilsson, Johan Miörner, Torben Schubert

Faculty Research, Scholarly, and Creative Activity

In this paper, we propose a theoretical and conceptual framework for articulating and studying changes in the global economic landscape and illustrate this framework in the current context. The framework pivots around the notion of rescaling, which is interpreted from a human agency perspective. We disentangle three theoretically distinct dimensions of rescaling and show how they play together using concrete examples. The theoretical and conceptual framework links the intended and unintended consequences of globalisation to current rescaling efforts, and allows us to investigate when, why, and how changes to the geography of economic relationships occur.

Florescence, Evan D. Jaccodine

Theses

Florescence is a photographic project that provokes conversation between mediums, methods, and attitudes in art and design. Starting as grainy, screened Risograph prints mounted into custom wood frames, the uniformity of mechanical reproduction is distorted by handmade craft elements. The images examine the materiality of making as part of the message they produce; they are both eclectic handmade objects and mass-produced products. These pictures intend to communicate an idea like an advertisement, except the message, meaning, or intention isn’t clear. I am interested in the moment when the viewer comes close enough to the image to see the prints' poor …

Assessment Of Digital Collaboration Skills, Esperanza Huerta, Ana Lidia Franzoni Velázquez, Scott Jensen

Faculty Research, Scholarly, and Creative Activity

This exploratory study proposes a methodology for assessing digital collaboration skills based on the students' actual behavior. Students' comments using a digital collaboration tool during a one-month long project were manually coded. This methodology is not context specific and can be used across different domains. This assessment contrasts with self-reported measures in which students rate themselves as already possessing collaboration skills. Finally, the study explores the use of generative AI to automatically code student's comments to alleviate the labor-intensive process that coding requires and to enable scalability in coding data.

Review Of Literature On Efficacy And Safety Of Birthing Positions With Emphasis On International Cultural Influences On Obstetric Care, Ava E. Retsch

Theses

• Background: When examining most non-Westernized societies, parturients hold all the power in the birthing space with traditional birth attendants and medical staff serving as guiding forces and protectors, not directors of the process. Social media in Western countries is filled with stories from birthing people who felt unsupported, ignored, or discriminated against by their healthcare providers; this is particularly prevalent in parturients who express a preference for non-supine birthing positions. Methods: This work is a review of the existing body of literature on quantitative and qualitative outcome measures of alternative birthing positions. In total, 44 articles were analyzed …

The Harms Of Heien: Pulling Back The Curtain On The Court's Search And Seizure Doctrine, Steven M. Goldstein --

Vanderbilt Law Review

In Heien v. North Carolina, the Supreme Court held that individuals can be seized on the basis of reasonable police mistakes of law. In an opinion authored by Chief Justice Roberts, the eight-Justice majority held that the Fourth Amendment’s prohibition of “unreasonable” seizures does not bar legally mistaken seizures because “[t]o be reasonable is not to be perfect.” Concurring, Justice Kagan, joined by Justice Ginsburg, emphasized that judicial condonation of police mistakes of law should be “exceedingly rare.” In a solo dissent, Justice Sotomayor fairly “wonder[ed] why an innocent citizen should be made to shoulder the burden of being seized …

Access To Justice For Black Inventors, Jordana R. Goodman, Khamal Patterson

Vanderbilt Law Review

To receive a patent, an inventor must meet certain inventive and procedural standards. Their invention must be novel, nonobvious, and written in such a way that any person skilled in the inventive subject can make and use the invention without undue experimentation. This process is far from objective.

An inventor is not always communicating within their own social circle. An inventor is required to communicate their invention so that a patent examiner believes a person having ordinary skill in the art ("PHOSITA") would recognize the invention as nonobvious. Moreover, a fictitious skilled person must be able to make and use …

Ownership Topology Of Vertically-Scaled Agile, William Dabney

Theses

Much as Scrum, Kanban, and XP are used to structure team-level agility, those wishing to take agility beyond the team level often turn to proven solutions. The most popular, which aim to scale development by adding teams under a shared collective ownership rather than separating them into discrete units, are the Scaled Agile Framework (SAFe), Large Scale Scrum (LeSS), and Nexus. These frameworks advocate for aligning ownership subdivisions along features rather than code, which allows teams working on the same product to do so autonomously. While the benefits of this have been researched, the topology of ownership in these frameworks …

Extraordinary Punishment: Conditions Of Confinement And Compassionate Release, Meredith B. Esser

Scholarly Works

People experience severe forms of harm while incarcerated, including medical neglect, prolonged solitary confinement, sexual and physical violence, and a host of other ills. But civil rights litigation under the Eighth Amendment the most common vehicle through which people seek to redress these harms presents significant practical and doctrinal barriers to incarcerated plaintiffs. Most notably, the Eighth Amendment's "deliberate indifference" standard asks not whether a person has been harmed, but instead requires plaintiffs to demonstrate a criminally reckless mental state on the part of prison officials. Further, Eighth Amendment remedies are limited to damages or injunctions, which may not adequately …

Who Bears The Burden When Prison Guards Rape?, Meredith B. Esser

Scholarly Works

Several recent scandals have highlighted the continued problem of institutional sexual abuse within the federal Bureau of Prisons ("BOP"). Most notoriously, the rampant sexual abuse of women incarcerated at Federal Correctional Institution ("FCI") Dublin, also known as the "rape club," resulted in the prosecution and conviction of several high-ranking officials within FCI Dublin, including both the former Warden and former Chaplain who worked there for several years. In response to these patterns of misconduct, the Federal Sentencing Commission's new guidelines, which went into effect on November 1, 2023, now allow for victims of custodial sexual assault to apply for early …

Building Resilience: The Role Of Public Private Partnerships In Disaster Management For Vulnerable Communities, Latisha Nixon-Jones

Scholarly Works

This essay provides a compelling historical analysis of the legislative developments that have shaped the current framework of disaster management in the United States. By tracing the evolution of these laws, it highlights a crucial shift in disaster responsibility—from centralized government agencies to a shared burden with the communities they aim to protect. In response to this shift, I propose that disaster management agencies adopt a socio-legal framework designed to guide the formation of public- private partnerships (PPPs). Such a framework would offer a structured approach to balancing transparency with the profitability goals that often characterize private involvement in public …
