The Precarious Art Of Classifying Facts, Allison Orr Larsen

Faculty Publications

In their terrific new article, Fact Stripping, Joseph Blocher and Brandon Garrett bring formidable expertise from their respective fields to tackle the inscrutable puzzle of appellate fact review.

[...]

In this short reply I will add to Blocher and Garrett’s illuminating work by exploring a foundational confusion their article exposes. I will first explain why classifying facts as either suitable for trial or not is a very fraught endeavor; I will then argue that this difficulty allows for significant manipulation and the risk of unprincipled application. Finally, I will nod to prior work and forecast future work where I …

Professionalizing A Student’S Library Employment Through Experiential Learning Workshops, Marissa Anne Bischoff, Matt Armstrong, David Waddell

Faculty Publications

If intentional, college students in campus jobs can develop professional skills valued in the post-college workforce. However, many students are not likely to realize the potential of their experience without advisement or instruction that teaches them how to reflect on experience and articulate its value, usually in the form of a resume or in an interview. This study examines the value of three workshops to help students reflect on their development of NACE career readiness competencies as a result of their library work experience. Survey and focus group data suggest students’ confidence in their ability to articulate and apply their …

A Codified Liabilty Regime To Stimulate Greater Investment In Subpatentable Innovation, Ana Santos Rutschman, Jerome H. Reichman

Faculty Publications

The global intellectual property system rests on a distinction between exclusive property rights and free competition. Exclusive rights vary in strength and intensity, but the opposite of protection is almost always free competition. Distinctions of intensity are drawn in terms of the length of protection given to different subject matters plus variable lists of exceptions and limitations to exclusive rights. But the bottom line is that, when protection is not available under the existing system, free competition prevails, and vice-versa (i.e., where there is exclusivity, free competition is deferred for a specified period of time).

This Article departs from a …

The Nitrogen Footprint Of Ukraine: Why Personal Consumption Matters, Sergiy Medinets, Allison M. Leach, Tetiana Pavlik, Volodymyr Medinets, James N. Galloway

Faculty Publications

Unintended reactive nitrogen (N) losses from agriculture, energy and transportation pose significant environmental hazards, including eutrophication, acidification, water and air pollution, biodiversity loss, human health risks and climate change. The concept of a nitrogen footprint (NF) emerges as a pivotal metric, reflecting potential N losses in the entire production-consumption chain of goods and services used by an individual within a defined timeframe.In a pioneering assessment of per capita NF in Ukraine, key factors, such as the food production chain, consumption patterns, connection to wastewater treatment (WWT) system and the efficacy of WWT facilities, were identified as critical components.

Effect Of Teacher Social Support On Students’ Emotions And Learning Engagement: A U.S.-Chinese Classroom Investigation, Moyi Jia, Jiuqing Cheng

Faculty Publications

Psychological and instructional communication researchers increasingly recognize the significance of student emotions in determining their engagement in the classroom. Under the direction of Emotional Response Theory (Mottet, Frymier, & Beebe, 2006), this study aims to establish a model of a college instructor’s social support, student positive and negative emotions, and student engagement in learning. It also attempts to extend this research by examining cultural differences in U.S. and Chinese classrooms and how these factors influence teacher behavior and student emotions. The result demonstrates the mediating effects of student positive emotions between teacher support and student engagement in both cultures. In …

Women At Work: Pathways From Gender Stereotypes To Gender Bias And Discrimination, Madeline E. Heilman, Suzette Caleo, Francesca Manzi

Faculty Publications

Despite important advances, gender-based discrimination continues to hin-der women’s career progress. This review examines the role that gender stereotypes play in promoting gender bias and discrimination. After review- ing what is known about the content of gender stereotypes and examining both their descriptive and prescriptive aspects, we discuss two pathways through which stereotypes result in discrepant work outcomes for women and men. First, we consider how the characterization of women as com- munal but not agentic conflicts with the perceived demands of many male gender-typed jobs and fields, thus promoting perceptions of women’s lack of competence in those areas. Second, …

The Cetacean Sanctuary: A Sea Of Unknowns, Jason N. Bruck

Faculty Publications

Housing cetaceans in netted sea pens is not new and is common for many accredited managed- care facilities. Hence, the distinction between sanctuary and sea pen is more about the philosophies of those who run these sanctuary facilities, the effects of these philosophies on the animals’ welfare, and how proponents of these sanctuaries fund the care of these animals. Here, I consider what plans exist for cetacean sanctuaries and discuss the caveats and challenges associated with this form of activist-managed captivity. One goal for stakeholders should be to disregard the emotional connotations of the word “sanctuary” …

Machine-Learning-Assisted Leak Detection Using Distributed Temperature And Acoustic Sensors, Hayden Gemeinhardt, Jyotsna Sharma

Faculty Publications

Small leaks, many of which often go undetected using conventional gauges, remain an urgent problem for an aging pipeline infrastructure. This article proposes a method that allows for an automated and robust leak detection and localization system by fusing distributed acoustic sensor (DAS) and distributed temperature sensor (DTS) data for machine learning. Distributed fiber-optic sensing creates an advantage over conventional gauges by providing real-time continuous measurements along the entire length of the fiber-instrumented pipeline at a high spatiotemporal resolution and sensitivity that can detect small leaks, as well as the leak location. High sensitivity, however, can create noisy data. Thus, …

The effects of climate change depend on specific local circumstances, posing a challenge for worldwide research to comprehensively encompass the diverse impacts on various local social-ecological systems. Here we use a place-specific but cross-culturally comparable protocol to document climate change indicators and impacts as locally experienced and analyze their distribution. We collected first-hand data in 48 sites inhabited by Indigenous Peoples and local communities and covering all climate zones and nature-dependent livelihoods. We documented 1,661 site-agreed reports of change corresponding to 369 indicators. Reports of change vary according to climate zone and livelihood activity. We provide compelling evidence that climate …

Low Complexity Doa Estimation Of Multiple Coherent Sources Using A Single Direct Data Snapshot, Ahmed A. Hussain, Nizar Tayem, Abdel-Hamid Soliman

Faculty Publications

The direction of arrival (DOA) estimation of multiple radio frequency (RF) coherent signals using conventional algorithms such as Multiple Signal Classification (MUSIC), Estimation of the Signal Parameters via the Rotational Invariance Technique (ESPRIT), and their variants is computationally complex and usually requires a large number of data snapshots for accurate estimation. As the number of antenna elements grows, particularly in massive MIMO systems, the complexity of real-time DOA estimation algorithms significantly rises, placing higher demands on computational power and memory resources. In this paper, we present an efficient approach that operates effectively with just a single snapshot for DOA estimation …

Training Data Augmentation With Data Distilled By Principal Component Analysis, Nikolay Metodiev Sirakov, Tahsin Shahnewaz, Arie Nakhmmani

Faculty Publications

This work develops a new method for vector data augmentation. The proposed method applies principal component analysis (PCA), determines the eigenvectors of a set of training vectors for a machine learning (ML) method and uses them to generate the distilled vectors. The training and PCA-distilled vectors have the same dimension. The user chooses the number of vectors to be distilled and augmented to the set of training vectors. A statistical approach determines the lowest number of vectors to be distilled such that when augmented to the original vectors, the extended set trains an ML classifier to achieve a required accuracy. …

Incorporating Unicorns: An Empirical Analysis, Anat Alon-Beck

Faculty Publications

There is a growing concern among regulators and academics about how to regulate unicorns - entities large enough to have a public impact yet remaining in the private domain. An examination of corporate charters within a selected sample of unicorn firms reveals an important finding: 97% of these entities are incorporated in Delaware. This concentration provides Delaware with significant leverage to shape regulatory frameworks, especially concerning the protection of parties who may lack the ability to safeguard their interests through contractual means.

This groundbreaking discovery on the dominance of Delaware showcases a substantial deviation from incorporation trends in other business …

Medical Authority And The Right To Life, B. Jessie Hill

Faculty Publications

This essay briefly explores this relationship between the understandings—existing and potential—of the right to “life” and the role of medical authority in constitutional abortion rights litigation. It proceeds as follows. Part I describes the dichotomy between two different understandings of “life” in U.S. legal discourse, with a particular focus on cases dealing with the so-called “right to die.” Part II then explains why this dichotomy is relevant in the post-Dobbs abortion rights context, as it holds the promise of an alternate path to protection for abortion rights at the federal and state levels. Part II also discusses how and why …

Revising Llm Text To (Re)Discover Rhetoric In A Graduate Seminar, Clancy Ratliff

Faculty Publications

In this essay, I share an assignment that asks students to engage in rhetorical revision of LLM text using a changelog table as a tool to document the revision. To demonstrate to the students what I was asking them to do, I did the assignment myself, and my example is included in this chapter as well. I argue that the style of generated text from LLMs calls for increased resistance to the norms and conventions of school writing and an embrace of writing that’s more rhetorical: a bit more personal, risky, rule-breaking, creative, and experimental, intentionally centering purpose and audience. …

Fruit, represented by banana plant leaf data, (3.) Flower, represented by …

Restricting Academic Freedom At Universities: How Corporations Contribute To The Problem, Hani Morgan

Faculty Publications

Industry-funded research can prevent academic freedom from thriving at universities. It can also lead to misleading research that harms consumers. This book chapter focuses on how corporations sometimes use methods that contribute to the corruption of science and includes descriptions of several cases that occurred at universities. Some of the methods that can lead to deception involve agreements university researchers sometimes sign that prevent them from publishing their results without a corporation’s approval. Other methods include requiring researchers to use research designs that will make a corporation’s products seem beneficial to consumers. Corporations can also require researchers to sign agreements …

Faculty Publications

With surface temperatures already reaching unprecedented highs, resulting in significant adverse consequences for societies and ecosystems, there are increasing calls to expand research into climate interventions, including Stratospheric Aerosol Intervention (SAI). However, research and dissemination are currently fragmented and would benefit from a comprehensive international assessment of the current state of knowledge regarding impacts, risks, and recommendations for future SAI research directions. The goals of a scientific assessment would be to describe the current state of SAI research and evaluate proposed scenario-strategy combinations through well-designed evaluation guidelines. The suggested iterative approach would integrate natural and social science considerations to guide …

A Scalogram-Based Cnn Approach For Audio Classification In Construction Sites, Michele Scarpiniti, Raffaele Parisi, Yong Cheol Lee

Faculty Publications

The automatic monitoring of activities in construction sites through the proper use of acoustic signals is a recent field of research that is currently in continuous evolution. In particular, the use of techniques based on Convolutional Neural Networks (CNNs) working on the spectrogram of the signal or its mel-scale variants was demonstrated to be quite successful. Nevertheless, the spectrogram has some limitations, which are due to the intrinsic trade-off between temporal and spectral resolutions. In order to overcome these limitations, in this paper, we propose employing the scalogramas a proper time–frequency representation of the audio signal. The scalogram is defined …

The New Marshmallow: The Effects Of Screen Use On Children's Ability To Delay Gratification, Benjamin Richardson, P. Thomas Fife, Joseph Steed, Caroline Crane, James Gaskin
