New Threats To Campus Protest, Timothy Zick
New Threats To Campus Protest, Timothy Zick
Faculty Publications
This symposium Essay focuses on how universities responded, both initially and after the fact, to campus protests concerning the Hamas-Israel War. During those protests students and others erected encampments, held demonstrations, displayed signs, vandalized university property, and occupied buildings. Some protesters communicated anti-Semitic tropes and slogans. Although a few university leaders responded to the protests by negotiating with protest leaders, most relied on law enforcement and security to clear encampments and restore order. Since the initial protests, universities have adopted a spate of new policies that threaten campus protest. These measures include cancellation of already-permitted demonstrations, content-based speech restrictions, bans …

Contemporary legal scholarship seeks to diagnose populist antagonism towards national and international law and warn about the challenges it poses to the cooperation needed to respond to global threats. What this scholarship overlooks, however, is the role that major shifts in international legal normativity and conceptions of global governance have themselves played in incubating the conditions far the rise of populism. Against the prevailing literature, this Article argues that the key to unlocking this puzzle is recognition that populism, rather than constituting an external social pathology, is a mode of politics arising internal to the intellectual history and practice of …
Legal And Policy Responses To Sexual Harassment In Housing, Rigel C. Oliveri
Legal And Policy Responses To Sexual Harassment In Housing, Rigel C. Oliveri
Faculty Publications
The sexual harassment of low-income women by their housing providers is a clear national problem that has only recently become the focus of coordinated nationwide enforcement efforts by federal agencies, including the Department of Justice. While these developments are welcome, the problem requires proactive responses as well. This Essay examines data from a study of all of DOJ's sexual harassment in housing cases and uses this information to identify the most problematic types of housing providers and the most common forms of harassment. Specifically, harassment appears to occur most frequently in private rental housing and is perpetuated by managers (usually …
Co-Parents With Benefits, Jessica Feinberg
Co-Parents With Benefits, Jessica Feinberg
Faculty Publications
The relationshipbetween individuals who share a common child merits significant legal and societal attention. An increasingly high percentageofchildren are being raisedby parents who are not married to each other, and modern social science research demonstrates that the quality of the relationship between co-parents has serious implications for children's well-being. When co-parentage is unaccompanied by marriage, however, the law historically has attachedfew, if any, rights and obligations to the relationship. This historical disregard for the relationship between non-marital co- parents fails to promote children's best interests. Children whose parents are not marriedto each other should not be excludedfrom the benefits that …

Can Americans’ Trust In Local News Be Trusted? The Emergence, Sources, And Implications Of The Local News Trust Advantage, Erik Peterson, Joshua P. Darr, Maxwell B. Allamong, Michael Henderson
Faculty Publications
Despite eroding consensus about credible political news sources, much of the public still trusts local media. We assess the emergence, sources, and implications of the trust advantage local news holds over national media. We argue the public now uses a news outlet's local orientation as a shortcut to assess its credibility. In survey experiments, we find unfamiliar news outlets are trusted more when they have a local cue in their name. In surveys where people evaluate digital sources covering their community, this heuristic leads the public to trust unreliable information providers that signal a local focus more than high-quality sources …

There is robust evidence that juvenile justice contact during formative years is associated with deleterious outcomes. The effect of juvenile court intervention on youth homelessness, however, has received scant empirical attention despite evidence that many justice-involved youth are represented in the unhoused youth and adult population. This study leverages data collected from the Crossroads Study (N = 1115), a longitudinal, multi-site study to explore the impact of formal processing on subsequent experiences with homelessness. This study found that even when accounting for the effect of detention and other factors associated with youth homelessness, youth who were formally processed were twice …

Complex Models Of Sequence Evolution Improve Fit, But Not Gene Tree Discordance, For Tetrapod Mitogenomes, Benjamin S. Toups, Robert C. Thomson, Jeremy M. Brown
Faculty Publications
Variation in gene tree estimates is widely observed in empirical phylogenomic data and is often assumed to be the result of biological processes. However, a recent study using tetrapod mitochondrial genomes to control for biological sources of variation due to their haploid, uniparentally inherited, and non-recombining nature found that levels of discordance among mitochondrial gene trees were comparable to those found in studies that assume only biological sources of variation. Additionally, they found that several of the models of sequence evolution chosen to infer gene trees were doing an inadequate job of fitting the sequence data. These results indicated that …

Book challenges and censorship have long played a significant role in the cultural and educational landscapes of the United States. In recent years, Louisiana has become a focal point in national conversations about intellectual freedom, public and school library governance, parental rights, and the political pressures surrounding children and young adult literature. This dynamic environment has led to significant debates about what materials should be accessible to young people, how libraries should be managed, and what role the state and local governments should play in determining the availability of information. The rise in book challenges across Louisiana reflects national trends …

JWST, despite not being designed to observe astrophysical phenomena that vary on rapid timescales, can be an unparalleled tool for such studies. If timing systematics can be controlled, JWST will be able to open up the subsecond infrared timescale regime. Rapid time-domain studies, such as lag measurements in accreting compact objects and solar system stellar occultations, require both precise interframe timing and knowing when a time series begins, down to an absolute accuracy significantly below 1 s. In this work, we present two long-duration observations of the deeply eclipsing double white dwarf system ZTF J153932.16+502738.8, which we use as a …
Critical Filaments And Superconductivity In Quasiperiodic Twisted Bilayer Graphene, Xinghai Zhang, Justin H. Wilson, Matthew S. Foster
Critical Filaments And Superconductivity In Quasiperiodic Twisted Bilayer Graphene, Xinghai Zhang, Justin H. Wilson, Matthew S. Foster
Faculty Publications
Multilayer moiré materials can exhibit topological electronic features yet are inherently quasiperiodic - leading to wave-function interference whose Anderson-localizing tendency can be mitigated by topology. We consider a quasiperiodic variant of the chiral Bistritzer-MacDonald model for twisted bilayer graphene with two incommensurate moiré potentials that serves as a toy model for twisted trilayer. We observe "filaments"linking magic angles with enhanced density of states and fractal wave functions that evade localization; states away from the filaments mimic fractal surface states of dirty topological superconductors. We demonstrate that topological quasiperiodicity can broadly enhance superconductivity without magic-angle fine-tuning.

US and EU flood mitigation policy both incorporate considerations of costs and benefits, and in recent years have taken steps to encourage accounting for positive and negative effects on vulnerable populations, broader non-market environmental impacts, and downstream effects beyond the target area of projects of flood mitigation projects. This work highlights the extent to which previous academic flood mitigation Benefit-Cost Analyses (BCA) papers have comprehensively considered such project effects. We do so through a systematic, PRISMA-style, review of BCA literature in the broader field of flood hazard mitigation and resilience decision-making. Our results suggest 1) most projects focus on monetizing …

Understanding the diversity-productivity relationship (DPR) is crucial for elucidating the ecological functions of marine bacterioplankton. However, studies have often focused on species diversity, neglecting phylogenetic diversity, which may offer deeper insights into the complex ecological processes shaping DPR in natural systems. This study addressed this gap by exploring the role of phylogenetic diversity in bacterioplankton productivity in the northern South China Sea, a coastal ecosystem influenced by estuarine plumes. We aimed to disentangle the mechanisms driving DPR and investigate how estuarine plumes modulate these processes. Our results show that the substantial enhancement of phytoplankton production by the Pearl River plume …

Environmentally persistent free radicals (EPFRs) are stable free radicals formed on particulate matter (PM) through processes such as combustion and pyrolysis. These free radicals are generated on transition metal oxide surfaces in the presence of aromatic precursors. Exposure to EPFRs occurs primarily via inhalation of PM deriving from combustion, traffic, industrial activities, and both indoor and outdoor burning. Other environmental factors that might generate EPFRs are radon, electronic and tobacco cigarettes. EPFRs exhibit unexpectedly long half-lives, ranging from several weeks to, in some cases, several years. EPFRs may be carbon-centered, oxygen-centered or mixed, identified by g-values exhibited in electron paramagnetic …

Incommensurate structures come from stacking the single layers of low dimensional materials on top of one another with misalignment such as a twist in orientation. While these structures are of significant physical interest, they pose many theoretical challenges due to the loss of periodicity. This paper studies the physical observables of continuum Schrodinger operators for incommensurate systems. We characterize the density of states and local density of states in real and reciprocal spaces, and develop novel numerical methods to approximate them. In particular, we (i) justify the thermodynamic limit of the density of states and local density of states via …

Realization Of Unitary Representations Of The Lorentz Group On De Sitter Space, Jan Frahm, Karl Hermann Neeb, Gestur Ólafsson

This paper builds on our previous work in which we showed that, for all connected semisimple linear Lie groups G acting on a non-compactly causal symmetric space M=G/H, every irreducible unitary representation of G can be realized by boundary value maps of holomorphic extensions in distributional sections of a vector bundle over M. In the present paper we discuss this procedure for the connected Lorentz group G=SO1,d(R)e acting on de Sitter space M=dSd. We show in particular that the previously constructed nets of real subspaces satisfy the locality condition. Following ideas of Bros and Moschella from the 1990’s, …

The Ross Sea I glaciation, marked by the northward advance of the Ross Ice Sheet (RIS) in the Ross Sea, east Antarctica, corresponds with the last major expansion of the West Antarctic Ice Sheet during the last glacial period. During its advance, the RIS was grounded along the southern Victoria Land coast, completely blocking the mouths of several of the McMurdo Dry Valleys (MDVs). Several authors have proposed that very large paleolakes, proglacial to the RIS, existed in many of the MDVs. Studies of these large paleolakes have been key in the interpretation of the regional landscape, climate, hydrology, and …

The synthesis of heavy elements in supernovae is affected by low-energy (n,p) and (p,n) reactions on unstable nuclei, yet experimental data on such reaction rates are scarce. The SECAR (SEparator for CApture Reactions) recoil separator at FRIB (Facility for Rare Isotope Beams) was originally designed to measure astrophysical reactions that change the mass of a nucleus significantly. We used a novel approach that integrates machine learning with ion-optical simulations to find an ion-optical solution for the separator that enables the measurement of (p,n) reactions, despite the reaction leaving the mass of the nucleus nearly unchanged. A new measurement of the …

In this study, we perform detailed spectroscopic modeling to analyze the interaction of circumstellar material (CSM) with ejecta in both hydrogen-rich and hydrogen-poor superluminous supernovae (SLSNe), by systematically varying properties such as the CSM density, composition, and geometry to explore their effects on spectral lines and light-curve evolution. Using advanced radiative transfer simulations with the new, open-source SuperLite code to generate synthetic spectra, we identify key spectroscopic indicators of CSM characteristics. Our findings demonstrate that spectral lines of hydrogen and helium exhibit significant variations due to differences in CSM mass and composition. In hydrogen-rich Type II SLSNe, we observe pronounced …

We use density functional methods to identify the atomic configurations of H and D atoms trapped by O impurities embedded in bulk Nb. The O atoms are located at the octahedral position in the Nb body-centered cubic (BCC) lattice, and H (D) atoms tunnel between two degenerate tetrahedral sites separated by a mirror plane. Using nudged elastic band (NEB) methods, we calculate the double-well potential for O-H and O-D impurities and the wave functions and tunnel splittings for H and D atoms. Our results agree with those obtained from analysis of heat capacity and neutron scattering measurements on Nb with …

Chemotherapy treatment-related side effects are common and increase the risk of suboptimal outcomes. Exercise interventions during cancer treatment improve self-reported physical functioning, fatigue, anxiety, and depression, but it is unclear whether these interventions improve important clinical outcomes, such as chemotherapy relative dose intensity. The National Cancer Institute funded the Exercise and Nutrition to Improve Cancer Treatment-Related Outcomes (ENICTO) Consortium to address this knowledge gap. This article describes the mechanisms hypothesized to underpin intervention effects on clinically relevant treatment outcomes, briefly outlines each project’s distinct research aims, summarizes the scope and organizational structure of ENICTO, and provides an overview of the …

Tunnel ionization (TI) underlies many important ultrafast processes, such as high-harmonic generation and strong-field ionization. Among the existing theories for TI, many-electron weak-field asymptotic theory (ME-WFAT) is by design capable of accurately treating many-electron effects in TI. An earlier version of ME-WFAT relied on an accurate representation of the asymptotic tail of the orbitals, which hindered its implementation in Gaussian-basis-set-based quantum chemistry programs. In this work, we reformulate ME-WFAT in the integral representation, which makes the quality of the asymptotic tail much less critical, hence greatly facilitating its implementation in standard quantum chemistry packages. The integral reformulation introduced here is …
