Faculty Publications

Artificial ocean fertilization (AOF) aims to safely stimulate phytoplankton growth in the ocean and enhance carbon sequestration. AOF carbon sequestration efficiency appears lower than natural ocean fertilization processes due mainly to the low bioavailability of added nutrients, along with low export rates of AOF-produced biomass to the deep ocean. Here we explore the potential application of engineered nanoparticles (ENPs) to overcome these issues. Data from 123 studies show that some ENPs may enhance phytoplankton growth at concentrations below those likely to be toxic in marine ecosystems. ENPs may also increase bloom lifetime, boost phytoplankton aggregation and carbon export, and address …

Subchronic Oral Cylindrospermopsin Exposure Alters The Host Gut Microbiome And Is Associated With Progressive Hepatic Inflammation, Stellate Cell Activation, And Mild Fibrosis In A Preclinical Study, Punnag Saha, Macayla Upright, Dipro Bose, Subhajit Roy, Ayushi Trivedi, Madhura More, Geoff Scott Ph.D., Bryan W. Brooks, Saurabh Chatterjee

Faculty Publications

Epidemiological studies have reported a strong association between liver injury and incidences of hepatocellular carcinoma in sections of humans globally. Several preclinical studies have shown a strong link between cyanotoxin exposure and the development of nonalcoholic steatohepatitis, a precursor of hepatocellular carcinoma. Among the emerging threats from cyanotoxins, new evidence shows cylindrospermopsin release in freshwater lakes. A known hepatotoxin in higher concentrations, we examined the possible role of cylindrospermopsin in causing host gut dysbiosis and its association with liver pathology in a mouse model of toxico-pharmacokinetics and hepatic pathology. The results showed that oral exposure to cylindrospermopsin caused decreased diversity …

Insectdisease: Programmatic Access To The Ecological Database Of The World’S Insect Pathogens, Tad Dallas, Colin J. Carlson, Patrick R. Stephens, Sadie J. Ryan, David W. Onstad

Faculty Publications

Curated databases of species interactions are instrumental to exploring and understanding the spatial distribution of species and their biotic interactions. In the process of conducting such projects, data development and curation efforts may give rise to a data product with utility beyond the scope of the original work, but which becomes inaccessible over time. Data describing insect host–pathogen interactions are fairly rare, and should thus be preserved and curated with appropriate metadata. Here, we introduce the insectDisease R package, a mechanism for curating, updating and distributing data from the Ecological Database of the World's Insect Pathogens, a database of insect …

Association Between Dietary Inflammatory Index Score And Muscle Mass And Strength In Older Adults: A Study From National Health And Nutrition Examination Survey (Nhanes) 1999-2002, Lingzhi Chen, Jingjing Ming, Tianyi Chen, James Hébert Scd, Peng Sun, Li Zhang, Hongya Wang, Qingkuo Wu, Cancan Zhang, Nitin Shivappa Mbbs, Mph, Ph.D., Bo Ban

Purpose

Chronic low-grade systemic inflammation affects muscle protein metabolism. The dietary inflammatory index (DII®) is a tool designed to assess the inflammatory potential of the diet. The available data on the association between DII and sarcopenia are limited. We aimed to investigate the association of the DII with components of sarcopenia in individuals over 50 years of age.

Methods

This cross-sectional study used the National Health and Nutrition Examination Survey (NHANES) 1999–2002 dataset. Body composition was measured, and isokinetic strength of the knee extensors (peak force) was evaluated. Low muscle mass and strength were defined using sex-specific thresholds. Energy-adjusted DII …

Institutional Navigation Of Oceans Governance: Lessons From Russia And The United States Indigenous Multi-Level Whaling Governance In The Arctic, Abigail M. York, Eduard Zdor, Shauna Burnsilver, Tatiana Degai, Maria Monakhova, Svetlana Isakova, Andrey N. Petrov, Morgan Kempf

Faculty Publications

Oceans governance occurs through overlapping, multi-level institutions that often fail to recognize Indigenous sovereignty and self-determination. The International Whaling Commission (IWC) provides pathways for recognizing Indigenous rights. However, observed power asymmetries and cross-level local to international conflicts threatened subsistence rights and generated research and advocacy fatigue for Chukchi, Iñupiat, Saint Lawrence Island Yupik, and Siberian Yupik communities in the USA and Russia. We conduct an institutional analysis of Indigenous bowhead whaling governance based upon lived experiences of Indigenous authors, primary documents from co-management organizations, national agencies, the IWC, and extant literature. We explore how Indigenous co-management organizations increased sovereignty and …

Beyond “Study Skills”: A Curriculum-Embedded Framework For Metacognitive Development In A College Chemistry Course, Sonja Gamby, Christopher F. Bauer

Faculty Publications

There is a critical need for evidence-based metacognition instruction models with an ease of implementation. Three issues involved in advancing the implementation and assessment of metacognitive interventions are: (i) the lack of an operational framework for the development of metacognition; (ii) metacognition instruction models that lack a focus on explicitly engaging students’ self-perceptions; (iii) a lack of metacognitive interventions that are easy to implement and require minimal training. This study describes the development and implementation of a 10-week discussion-based module to promote metacognitive development as part of a general chemistry course at a community college. This curricular metacognition instruction model …

Second, for those cryptoassets that are not securities, this Article seeks to find a regulatory solution that balances promoting innovation with investor protection, just as the Securities and Exchange Commission (SEC) would do. To strike the right balance, this Article adopts a proposal by Ian Ayres and Alan Schwartz …

A World Without Prosecutors, Jeffrey Bellin

Faculty Publications

Bennett Capers’ article Against Prosecutors challenges us to imagine a world where we “turn away from prosecution as we know it,” and shift “power from prosecutors to the people they purport to represent.”

[...]

Capers joins a long line of authors seeking to attack mass incarceration by reducing the role of prosecutors. I agree with these authors that we should dramatically shrink the footprint of American criminal law and ending the war on drugs is a good place to start. But while Capers styles his proposal as a “[r]adical change,” I find the focus on prosecutors in this context decidedly …

A New Feudalism: Selfish Genes, Great Wealth, And The Rise Of The Dynastic Family Trust (Dft), Eric Kades

Faculty Publications

Today’s record levels of economic inequality are infecting our future as the top 0.01% bequeath vast wealth to their descendants. With the death of the Rule Against Perpetuities (RAP), this inequality has the potential to harden social class lines—not just for a generation or two, but forever. Although it may sound implausible, interviews with estate lawyers serving very high-net-worth clients reveal that some members of the wealthiest tier of testators are already exploiting the RAP’s elimination, along with a tax loophole, to establish dynasty trusts that will financially empower their bloodline as long as it continues. Recent work in evolutionary …

By conducting three virtual focus group interviews with 18 international students, we identified four key themes that encapsulate participants’ challenges and experiences of online learning: social isolation in online learning spaces, difficulties with engaging in online class discussions and activities, limited opportunities for improving English proficiency in the online setting and limited academic support from faculty and advisors. Implications for research and practice to …

Sex And Coercion: Comments On Green's Criminalizing Sex, Michelle Madden Dempsey

Faculty Publications

In chapter seven of Stuart Green’s magnificent book, Criminalizing Sex, he considers the crime of rape by coercion. In doing so, he takes up several related questions, including how we should distinguish between coercive threats and so-called coercive offers, and how to distinguish between coercive and non-coercive offers. My comments proceed in five steps. In section one, I argue that we should not bother making any distinction between threats and offers, since the two are intertranslatable. In section two, I examine various baselines that might be used to identify coercive proposals (regardless of whether they appear in the form of …

Manipulating Facebook's Notification System To Provide Evidence Of Techno-Social Engineering, Brett Frischmann, Katherine Haenschen, Paul Ellenbogen

Faculty Publications

Techno-social engineering (TSE) theory argues that digital platforms shape and program human behaviors. We provide empirical evidence of this theory by introducing a novel method to conduct in-network studies on Facebook. We manipulate Facebook’s birthday notification system by recruiting confederates to change their birthday to a randomly assigned date and then measure network members’ responses in terms of whether they leave a greeting or question the veracity of the date. TSE theory leads us to expect that more participants will wish happy birthday on the fake date than question its veracity. We explore variables expected to predict heterogeneity in terms …

White Matter Hyperintensity Load Is Associated With Premature Brain Aging, Natalie Busby, Sarah Newman-Norlund, Sara Sayers, Roger Newman-Norlund, Sarah Wilson, Samaneh Nemati, Chris Rorden, Janina Wilmskoetter, Nicholas Riccardi, Rebecca Roth, Julius Fridriksson, Leonardo Bonilha

Faculty Publications

Background: Brain age is an MRI-derived estimate of brain tissue loss that has a similar pattern to aging-related atrophy. White matter hyperintensities (WMHs) are neuroimaging markers of small vessel disease and may represent subtle signs of brain compromise. We tested the hypothesis that WMHs are independently associated with premature brain age in an original aging cohort.

Methods: Brain age was calculated using machine-learning on whole-brain tissue estimates from T1-weighted images using the BrainAgeR analysis pipeline in 166 healthy adult participants. WMHs were manually delineated on FLAIR images. WMH load was defined as the cumulative volume of WMHs. A positive difference …

Substrate Availability And Not Thermal Acclimation Controls Microbial Temperature Sensitivity Response To Long-Term Warming, Luiz A.

Melillo, Kristen M. Deangelis

Faculty Publications

Microbes are responsible for cycling carbon (C) through soils, and predicted changes in soil C stocks under climate change are highly sensitive to shifts in the mechanisms assumed to control the microbial physiological response to warming. Two mechanisms have been suggested to explain the long-term warming impact on microbial physiology: microbial thermal acclimation and changes in the quantity and quality of substrates available for microbial metabolism. Yet studies disentangling these two mechanisms are lacking. To resolve the drivers of changes in microbial physiology in response to long-term warming, we sampled soils from 13- and 28-year-old soil warming experiments in different …

Water is essential for survival, but one in three individuals worldwide (2.2 billion people) lacks access to safe drinking water. Water intake requirements largely reflect water turnover (WT), the water used by the body each day. We investigated the determinants of human WT in 5604 people from the ages of 8 days to 96 years from 23 countries using isotope-tracking (2H) methods. Age, body size, and composition were significantly associated with WT, as were physical activity, athletic status, pregnancy, socioeconomic status, and environmental characteristics (latitude, altitude, air temperature, and humidity). People who lived in countries with a low human development …

An Assessment Of Future Tidal Marsh Resilience In The San Francisco Estuary Through Modeling And Quantifiable Metrics Of Sustainability, James T. Morris, Judith Z. Drexler, Lydia J.S. Vaughn, April H. Robinson

Faculty Publications

Quantitative, broadly applicable metrics of resilience are needed to effectively manage tidal marshes into the future. Here we quantified three metrics of temporal marsh resilience: time to marsh drowning, time to marsh tipping point, and the probability of a regime shift, defined as the conditional probability of a transition to an alternative super-optimal, suboptimal, or drowned state. We used organic matter content (loss on ignition, LOI) and peat age combined with the Coastal Wetland Equilibrium Model (CWEM) to track wetland development and resilience under different sea-level rise scenarios in the Sacramento-San Joaquin Delta (Delta) of California. A 100-year hindcast of …
