However, decision making related to these systems currently lacks meaningful sustainability considerations. To fill this gap, this research explores the life cycle impacts of wastewater and energy infrastructure using case studies, life cycle assessment methodologies, and stakeholder discussions. Environmental and economic impacts, which are more commonly quantified, as well as more difficult to quantify societal factors, are explored. The goal of this research is to help inform decision making and facilitate the consideration of the three pillars of sustainability (e.g., economic, environmental, and social) during the …

What’S “Controversial” About Esg? A Theory Of Compelled Commercial Speech Under The First Amendment, Sean J. Griffith

Nebraska Law Review

This Article uses the Securities and Exchange Commission’s SEC’s recent foray into Environmental, Social, and Governance ESG to illuminate ambiguities in First Amendment doctrine. Situating mandatory disclosure regulations within the compelled commercial speech paradigm, it identifies the doctrinal hinge as “controversy.” Rules compelling commercial speech receive deferential judicial review, provided they are purely factual and uncontroversial. The Article argues that this requirement operates as a pretext check, preventing regulators from exceeding the plausible limits of the consumer protection rationale.

Applied to securities regulation, the compelled commercial speech paradigm requires the SEC to justify disclosure mandates as a form of investor …

Party First, Ask Questions Later: Interrogating The Privacy Implications Of First-Party Data Collection, Conor Kane

Nebraska Law Review

NGTC “How Technology Regulates” Writing Competition Winner

This Article examines Google’s stated and potentially unstated justifications for ending support for the third-party cookie and the ripple effects this move creates for data collection across the digital advertising ecosystem. It argues that Google’s allegedly pro-privacy move and marketers’ allegedly pro-privacy switch to first-party data ignore and create privacy harms. The only way to protect privacy in the era of first-party data (and protect against future shifts in collection techniques) is to reconceive the corporation-consumer data relationship. On a broader level, this Article aims to provide a warning about the nature of …

Record High Room Temperature Resistance Switching In Ferroelectric-Gated Mott Transistors Unlocked By Interfacial Charge Engineering, Yifei Hao, Xuegang Chen, Le Zhang, Myung-Geun Han, Wei Wang, Yue-Wen Fang, Hanghui Chen, Yimei Zhu, Xia Hong

Department of Physics and Astronomy: Faculty Publications

The superior size and power scaling potential of ferroelectric-gated Mott transistors makes them promising building blocks for developing energyefficientmemory and logic applications in the post-Moore’s Law era. The close to metallic carrier density in the Mott channel, however, imposes the bottleneck for achieving substantial field effect modulation via a solid-state gate. Previous studies have focused on optimizing the thickness, charge mobility, and carrier density of single-layer correlated channels, which have only led to moderate resistance switching at room temperature. Here, we report a record high nonvolatile resistance switching ratio of 38,440% at 300 K in a prototype Mott transistor consisting …

Emotional Responses To Covid-19 Stressors Increase Information Avoidance About An Important Unrelated Health Threat, Christopher Gustafson, Kate Brooks, Syed Imran Ali Meerza, Amalia Yiannaka

Department of Agricultural Economics: Faculty Publications

The COVID-19 pandemic, like other crises, has had direct and indirect impacts on individuals, many of which have been negative. While a large body of research has examined the impacts of COVID-19 on people’s lives, there is little evidence about how COVID-19 affects decision-making broadly. Emotional responses to COVID-19-related stressors, such as illness and income loss, provide a pathway for these stressors to affect decision-making. In this study, we examine linkages between exposure to COVID-19-related stressors—focusing on temporally specific local case counts and loss of income due to the pandemic—and decisions to access information about antimicrobial resistance (AMR), another critically …

Induction And Suppression Of Gene Silencing In Plants By Nonviral Microbes, Eric Parperides, Kaoutar El Mounadi, Hernan Garcia Ruiz

Department of Plant Pathology: Faculty Publications

Gene silencing is a conserved mechanism in eukaryotes that dynamically regulates gene expression. In plants, gene silencing is critical for development and for maintenance of genome integrity. Additionally, it is a critical component of antiviral defence in plants, nematodes, insects, and fungi. To overcome gene silencing, viruses encode effectors that suppress gene silencing. A growing body of evidence shows that gene silencing and suppression of silencing are also used by plants during their interaction with nonviral pathogens such as fungi, oomycetes, and bacteria. Plant–pathogen interactions involve trans-kingdom movement of small RNAs into the pathogens to alter the function of genes …

White Privilege And Teacher Perceptions Of Teacher-Child Relationship Quality, Kathleen Moritz Rudasill, Colin M. Mcginnis, Sheng-Lun Cheng, Dwayne Ray Cormier, Natalie A. Koziol

Nebraska Center for Research on Children, Youth, Families, and Schools: Faculty Publications

In this study, we investigated differences in teachers’ perceptions of the teacher-child relationship from kindergarten through second grade as a function of child race and gender from the perspective of critical race theory and the cultural synchrony hypothesis. Given the extensive evidence of White privilege and anti-Black racism in the US education system, we expected that teachers, particularly White teachers, would perceive their relationships with White children more positively than with Black children. Controlling for family SES and child gender, results supported this hypothesis. Black boys had the highest risk of being perceived by teachers as having poor relationships with …
