Lear’S Daughters? Unenumerated Fundamental Rights And The Constitution, Thomas Halper

Publications and Research

How to determine whether fundamental unenumerated constitutional rights exist, and if so, what they are? The questions are of obvious enormous importance—witness the current controversy over abortion—and yet courts have generally been content to address the issues superficially, sometimes, cavalierly. Their treatment of the most common rationale, an historical/traditional consensus, exemplifies this shallow approach. The underdeveloped character of the argumentation on this topic stubbornly remains one of the most glaring shortfalls of modern constitutional law.

Futures On Dry Ground: Anthropology And Coastal Planning, Theodore Hilton, Sheehan Moore

Publications and Research

Around the world, governments, industry, and other actors are creating plans to save coasts from environmental crisis. Louisiana is one prominent example: levees and other measures protect oil and gas infrastructure from inundation as the wetlands buffer rapidly erodes—in large part due to that same industry. The state’s primary answer to land loss is a $50 billion Coastal Master Plan. To illuminate such responses in Louisiana and globally, this article reviews emerging literature and frames an anthropology of coastal planning around three themes: (1) novel orientations toward time and space, (2) the reproduction of power and capital in the name …

Molecular Mechanism Behind The Safe Immunostimulatory Effect Of Withania Somnifera, Kriti Kalpana, Shen Yap, Moriya Tsuji, Akira Kawamura

Publications and Research

Withania somnifera (L.) Dunal (family Solanaceae) is a medicinal plant known for, among many pharmacological properties, an immune boosting effect. Our recent study revealed that its key immunostimulatory factor is lipopolysaccharide of plant-associated bacteria. This is peculiar, because, although LPS can elicit protective immunity, it is an extremely potent pro-inflammatory toxin (endotoxin). However, W. somnifera is not associated with such toxicity. In fact, despite the presence of LPS, it does not trigger massive inflammatory responses in macrophages. To gain insights into the safe immunostimulatory effect of W. somnifera, we conducted a mechanistic study on its major phytochemical constituent, …

Changes To Sea Surface Temperatures And Vertical Wind Shear And Their Influence On Tropical Cyclone Activity In The Caribbean And The Main Developing Region, Keneshia Hibbert, Equisha Glenn, Thomas M. Smith, Jorge E. González-Cruz

Publications and Research

Sea surface temperatures and vertical wind shear are essential to tropical cyclone formation. TCs need warm SSTs and low shear for genesis. Increasing SSTs and decreasing VWS influences storm development. This work analyzes SST and VWS trends for the Caribbean, surrounding region, and the Atlantic hurricane main developing region from 1982–2020. Storm intensity increases significantly during this period. Annual and seasonal trends show that regional SSTs in the MDR are warming annually at 0.0219 °C yr⁻¹ and, per season, 0.0280 °C yr⁻¹. Simultaneously, VWS decreases during the late rainfall season, at 0.056 m/s yr⁻¹ in the …

Structure–Activity Relationship Studies On 6-Chloro-1-Phenylbenzazepines Leads To The Identification Of A New Dopamine D1 Receptor Antagonist, Rajan Giri, Hari K. Namballa, Vishwashiv Emogaje, Wayne W. Harding

Publications and Research

The 1-phenylbenzazepine template has yielded a number of D1R-like ligands, which, though useful as pharmacological tools, have significant drawbacks in terms of selectivity versus D5R as well as pharmacokinetic behavior. A number of 1-phenylbenzazepines contain a 6-chloro functional group, but extensive SAR studies around the 6-chloro-1-phenylbenzazepine framework have not been reported in the literature. To further understand the tolerance of the 6-chloro-1-phenylbenzazepine template for various substituent groups towards affinity and selectivity at D1R, we synthesized two series of analogs with structural variations at the C-7, C-8, N-3, C-3′ and C-4′ positions. The series 2 analogs differed from …

Ecological Niche Comparison Among Closely Related Tree Species Of Lauraceae Using Climatic And Edaphic Data, Laura J. Giraldo-Kalil, Gonzalo E. Pinilla Buitrago, Andrés Lira-Noriega, Francisco Lorea-Hernández, Juan Núñez-Farfán

Publications and Research

ABSTRACT:

Edaphic specialization is considered to promote ecological differentiation among closely related species of Damburneya (Lauraceae) occurring in sympatry. However, little is known about the effects of soil and other key environmental factors like climate on the ecological niche and distribution of these tree species. Here, we assessed the role of climate and soil on niche divergence and potential distribution of four Damburneya species whose distributions span Central America and Mexico. We performed ecological niche modeling with MaxEnt using three sets of environmental data: climatic-only, edaphic-only, and a combination of both, to characterize species niches and suitable distribution areas. Niche …

The Routes Of Introspection, Adriana Renero

Publications and Research

In “What forms could introspective systems take? A research programme”, François Kammerer and Keith Frankish aim to map the space of “possible forms of introspection” while lending themselves to questions about how different kinds of minds represent themselves. This paper aligns with Kammerer and Frankish’s research programme in embracing other possible forms of introspection; it provides an outline of how, in representing its mental states, an introspective system could take a selective, cumulative, and/or predictive route while underscoring the importance of considering routes of introspection. Although this work only explores human minds, it contributes to Kammerer and Frankish’s research programme …

Radiation-Induced Gastrointestinal (Gi) Syndrome As A Function Of Age, Hongyan Li, Herman C. Kucharavy, Carla Hajj, Liyang Zhao, Guoqiang Hua, Ryan Glass, Phillip B. Paty, Zvi Fuks, Richard Kolesnick, Karen Hubbard, Adriana Haimovitz-Friedman

Publications and Research

Previous studies show increased sensitivity of older mice (28–29 months) compared with young adult mice (3 months, possessing a mature immune system) to radiation-induced GI lethality. Age-dependent lethality was associated with higher levels of apoptotic stem cells in small intestinal crypts that correlated with sphingomyelinase activity, a source of pro-apoptotic ceramide. The objective of this study is to determine whether the cycling crypt base columnar cells (CBCs) in aging animals are specifically more sensitive to radiation effects than the CBCs in young adult mice, and to identify factors that contribute to increased radiosensitivity. Mortality induced by subtotal body radiation was …

Hamiltonian Structure Of 2d Fluid Dynamics With Broken Parity, Gustavo Machado Monteiro, Alexander G. Abanov, Sriram Ganeshan

Publications and Research

Isotropic fluids in two spatial dimensions can break parity symmetry and sustain transverse stresses which do not lead to dissipation. Corresponding transport coefficients include odd viscosity, odd torque, and odd pressure. We consider an isotropic Galilean invariant fluid dynamics in the adiabatic regime with momentum and particle density conservation. We find conditions on transport coefficients that correspond to dissipationless and separately to Hamiltonian fluid dynamics. The restriction on the transport coefficients will help identify what kind of hydrodynamics can be obtained by coarse-graining a microscopic Hamiltonian system. Interestingly, not all parity-breaking transport coefficients lead to energy conservation and, generally, the …

Inclusive Random Sampling In Graphs And Networks, Yitzchak Novick, Amotz Bar-Noy

Publications and Research

It is often of interest to sample vertices from a graph with a bias towards higher-degree vertices. One well-known method, which we call random neighbor or RN, involves taking a vertex at random and exchanging it for one of its neighbors. Loosely inspired by the friendship paradox, the method is predicated on the fact that the expected degree of the neighbor is greater than or equal to the expected degree of the initial vertex. Another method that is actually perfectly analogous to the friendship paradox is random edge, or RE, where an edge is sampled at random, and then one …

Logic As Applied Mathematics — With Particular Application To The Notion Of Logical Form, Graham Priest

Publications and Research

The word ‘logic’ has many senses. Here we will understand it as meaning an account of what follows from what and why. With contemporary methodology, logic in this sense – though it may not always have been thought of in this way – is a branch of applied mathematics. This has various implications for how one understands a number of issues concerning validity. In this paper I will explain this perspective of logic, and explore some of its consequences with respect to the notion of logical form.

Potential Anti-Alzheimer Properties Of Mogrosides In Vitamin B12-Deficient Caenorhabditis Elegans, Denia Cai Shi, Chunlin Long, Ella Vardeman, Edward J. Kennelly, Michael A. Lawton, Rong Di

Publications and Research

Vitamin B12 deficiency can lead to oxidative stress, which is known to be involved in neurodegenerative diseases such as Alzheimer’s disease (AD). Mogrosides are plant-derived triterpene glycosides that exhibit anti-inflammatory and antioxidant activity in animal cell lines and mouse models. Since amyloid-β toxicity is known to cause oxidative stress and damage to brain cells, we hypothesized that mogrosides may have a protective effect against AD. In this study, we investigated the potential anti-AD effect of mogrosides in vitamin B12-deficient wild-type N2 and in transgenic CL2355 Caenorhabditis elegans expressing amyloid-β peptide. Our data indicated that mogrosides have a beneficial effect on …

Fabrication And Errors In The Bibliographic Citations Generated By Chatgpt, William H. Walters, Esther Isabelle Wilder

Publications and Research

Although chatbots such as ChatGPT can facilitate cost-effective text generation and editing, factually incorrect responses (hallucinations) limit their utility. This study evaluates one particular type of hallucination: fabricated bibliographic citations that do not represent actual scholarly works. We used ChatGPT-3.5 and ChatGPT-4 to produce short literature reviews on 42 multidisciplinary topics, compiling data on the 636 bibliographic citations (references) found in the 84 papers. We then searched multiple databases and websites to determine the prevalence of fabricated citations, to identify errors in the citations to non-fabricated papers, and to evaluate adherence to APA citation format. Within this set of documents, …

People Are Curious About Immoral And Morally Ambiguous Others, Jordan Wylie, Ana Gantman

Publications and Research

Looking to the popularity of superheroes, true crime stories, and anti-heroic characters like Tony Soprano, we investigated whether moral extremity, especially moral badness, piques curiosity. Across five experiments (N = 2429), we examine moral curiosity, testing under what conditions the moral minds of others spark explanation-seeking behavior. In Experiment 1, we find that among the most widely watched Netflix shows in the US over a five-month period, the more immoral the protagonist, the more hours people spent watching. In Experiments 2a and 2b, we find that when given a choice to learn more about morally good, bad, ambiguous, or …

Lead Induced Differences In Bone Properties In Osteocalcin +/+ And −/− Female Mice, G. Yildirim, W. C. Budell, O. Berezovska, S. Yagerman, S. S. Maliath, P. Mastrokostas, S. Tommasini, T. L. Dowd

Publications and Research

Lead (Pb) toxicity is a major health problem and bone is the major reservoir. Lead is detrimental to bone, affects bone remodelingand is associated with elderly fractures. Osteocalcin (OC) affects bone remodeling, improves fracture resistance and decreases with age and in some diseases. The effect of lead in osteocalcin depleted bone is unknown and of interest. We compared bone mineral properties of control and Pb exposed (from 2 to 6 months) femora from female adult C57BL6 OC+/+ and OC−/− mice using Fourier Transform Infrared Imaging (FTIRI), Micro-computed tomography (uCT), bone biomechanical measurements and serum turnover markers (P1NP, CTX).

Aligning Retrograde Nuclear Cluster Orbits With An Active Galactic Nucleus Accretion Disc, Syeda S. Nasim, Gaia Fabj, Freddy Caban, Amy Secunda, K. E. Saavik Ford, Barry Mckernan, Jillian M. Bellovary, Nathan W. C. Leigh, Wladimir Lyra

Publications and Research

Stars and stellar remnants orbiting a supermassive black hole (SMBH) can interact with an active galactic nucleus (AGN) disc. Over time, prograde orbiters (inclination i < 90°) decrease inclination, as well as semimajor axis (a) and eccentricity (e) until orbital alignment with the gas disc (‘disc capture’). Captured stellar-origin black holes (sBH) add to the embedded AGN population that drives sBH–sBH mergers detectable in gravitational waves using LIGO–Virgo–KAGRA or sBH–SMBH mergers detectable with Laser Interferometer Space Antenna. Captured stars can be tidally disrupted by sBH or the SMBH or rapidly grow into massive ‘immortal’ stars. Here, we investigate the behaviour of polar and retrograde orbiters …

Feeling Analogue: Using Modular Synthesizers, Designing Synthesis Communities, Eliot Bates

Publications and Research

When Harald Bode nominally invented the modular synthesiser in 1960, it was not yet clear whether it was a musical instrument or a less-defined form of studio-sited audio technology (Subotnik 1970). Much of the technology, from the interface design to the specific parts, was shared with nonmusical test and measurement equipment. Sixty years later, hardware modular synthesis is used not just for musical creation but for noise, sound art and data sonification/visualization. Through an ethnographic study of the design and use of the Eurorack modular synthesis format, and of modular synthesis maker and user communities spread through North America, Europe …

The Role Of Preprocessing For Word Representation Learning In Affective Tasks, Nastaran Babanejad, Heidar Davoudi, Ameeta Agrawal, Manos Papagelis

Computer Science Faculty Publications and Presentations

Affective tasks, including sentiment analysis, emotion classification, and sarcasm detection have drawn a lot of attention in recent years due to a broad range of useful applications in various domains. The main goal of affect detection tasks is to recognize states such as mood, sentiment, and emotions from textual data (e.g., news articles or product reviews). Despite the importance of utilizing preprocessing steps in different stages (i.e., word representation learning and building a classification model) of affect detection tasks, this topic has not been studied well. To that end, we explore whether applying various preprocessing methods (stemming, lemmatization, stopword removal, …

Intimate Partner Violence Stigma: The Intersection Of Race And Socioeconomic Status, Antoinette Fleming

Dissertations and Theses @ UNI

Approximately 36% of all women in the United States will experience intimate partner violence (IPV) at some point in their lifetime (Smith et al., 2018). Intimate partner violence can cause physical injury, poor mental health, chronic health problems, hospitalization, disability, or death (Breiding et al., 2015). Stigma is another consequence associated with IPV. Many victims of IPV report feeling guilt, denial, shame, and embarrassment as a result of the intimate partner violence victimization (Lichtenstein, 2006). Additionally, African American (Black) victims may be more heavily stigmatized than European American (White) victims. Socioeconomic status (SES) may also affect a person’s perception of …

Application Of Artificial Treatment Wetland Systems In The English Coulee, Michael Anthony Rosati

Theses and Dissertations

Artificial treatment wetlands are commonly used for treating urban stormwater runoffand surface waters affected by agricultural runoff. While this method is well-established, its effectiveness can vary based on environmental, design, and hydraulic factors. In Grand Forks, ND, the English Coulee, a hydraulically altered class III stream, is currently experiencing elevated nutrient pollution, specifically nitrates and phosphates. Implementing a floating treatment wetland (FTW) system in the English Coulee is a potential solution. This paper analyzes the feasibility and requirements for a 4.64 ha FTW to achieve a minimum of 50% nutrient removal, utilizing comprehensive modeling approaches. Through HEC-HMS and HECRAS simulations, …

Parental Involvement For Spanish-Speaking English Learners: Teachers’ Perspectives, Olawumi Oluranti Salako

Theses and Dissertations

The benefit of parental involvement (PI) cannot be underestimated, most specifically, the PI that operates on mutual trust and respect, and balancing of power between homes and schools. It is particularly beneficial to students who are learning English as a second language because their parents can partner with educators to close the achievement gap. However, literature has revealed that most schools have operated using the unidirectional approach in which parents and family members are being alienated from their children’s education due to several factors like an imbalance of power between home and school (Cooper, 2009; Ishimaru et al., 2016). Hence, …
