The Shadow Pandemic: The Response To Domestic Violence In The Wake Of Covid-19 And What We Can Carry Forward, Presley Sneed

Georgia Criminal Law Review

When the COVID-19 virus brought the pandemic to the United States in March of 2020, the legal system was not prepared for the increase in domestic and intimate partner violence that would follow. The United Nations (UN) later identified this social phenomenon as a second pandemic, a “shadow pandemic” that resulted from an increase in stay-at-home orders and a decrease in support services for victims. By the end of 2021, forty-five percent of women globally reported either they themselves or a woman they know had experienced some form of domestic or intimate partner violence since the emergence of COVID-19.

Enhancement Of Phenolic, Flavonoid, And Biological Activi-Ties In Fermented Pea (Pisum Sativum) Extracts Via Frac-Tionation, Anastasia Fitria Devi, Euis Filailla, Setyani Budiari, Hani Mulyani, Nina Artanti

Karbala International Journal of Modern Science

In this study, peas were fermented for 24 h using either Rhizopus oligosporus or Aspergillus oryzae. The resulting fermented peas, along with unfermented peas, were extracted using either methanol or water. The methanol extracts showed greater improvements following fermentation compared to the water extracts, as shown by the IC₅₀ values, which progressed from >500 to ≤200 µg/mL, as determined via the 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) method. Consequently, further fractionations focused on the methanol extracts of the fermented peas. Six bands were resolved on thin-layer chromatography plates for each extract. Their positions demonstrated significant effects (p < 0.05) on bioactivity. The bottom band (i.e., Band 1) exhibited approximately 70% inhibition, as determined via the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and 35% inhibition according to the ABTS method, while the other bands displayed lower to negligible inhibition. Band 5 displayed 85–97% cytotoxicity, while Band 1 did not show any cytotoxicity. The total phenolic content (TPC) of Band 1 and the total flavonoid content (TFC) of Band 6 increased 4.4- and 8.9-fold, respectively, compared to those of the unfractionated extracts. Furthermore, a correlation analysis revealed a strong correlation between TFC and the three observed bioactivities. The different cultures significantly (p < 0.05) affected the antioxidant activity of either the fermented pea extracts or the resulting bands, as determined via the DPPH method. These results indicated that fermentation enhanced the antioxidant activity of peas. Subsequent fractionations separated and concentrated compounds from the fermented peas, improving the bioactivities, TPC, and TFC of the resulting fractions.

Filling The Sackett Gap: The Private Governance Option, Michael P. Vandenbergh, Elodie O. Currier Stoffel, Steph Tai

Minnesota Law Review Vols. 106:2 onward (2021-present)

The Supreme Court’s decision in Sackett v. EPA reversed fifty years of federal Clean Water Act wetlands protections and removed federal oversight from roughly half of the wetlands in the United States. This Article proposes a viable new conceptual model and tools to close the Sackett Gap—the gap between the wetlands protected before and after Sackett. Scholars have argued for federal measures to fill the Sackett Gap, but these actions face substantial challenges. Congress is unlikely to adopt new wetlands legislation, agencies are constrained by Sackett’s expansive language, the end of Chevron deference, and the 2024 presidential election, and lower …

Catching Nutients In A Net: Collective Action, Institutional Impediments, And The Mississippi River Watershed, Jonathan Rosenbloom

Minnesota Law Review Vols. 106:2 onward (2021-present)

Thousands of local governments in the Mississippi River watershed possess regulatory land use authority. From a narrow law and economics standpoint, when these entities extract from, add to, or pollute the watershed, it may appear as a classic tragedy of the commons problem. The tragedy sounds something like this: local governments act “rationally” to avoid regulating in a way that reduces pollution in the waterway because such regulation would increase costs. Further, local governments avoid paying the costs associated with treating or reducing the level of contaminants in the water before ushering them downstream. While this analysis might partially explain …

The Bogeyman Of Environmental Regulation: Federalism, Agency Preemption, And The Roberts Court, Kamaile A.N. Turčan

Minnesota Law Review Vols. 106:2 onward (2021-present)

In a trio of environmental cases—West Virginia v. EPA, Sackett v. EPA, and Loper Bright v. Raimondo—the Roberts Court curtailed the federal regulatory power and produced corresponding deregulatory outcomes under seemingly neutral legal principles. This Article interrogates the doctrinal coherency of the Roberts Court’s jurisprudence by applying the rationales of these cases to climate change litigation. Climate change policies advanced by state and local governmental plaintiffs represent the inverse of what the Court has previously rejected. The regulatory burdens arise under state, not federal, law. In this analysis, the Article advances a previously undertheorized aspect of the trio’s combined effect: …
