The Water Mills Of The Historic Río Arriba In Northcentral New Mexico, 1598-1975, José A. Rivera Ph.D, Thomas F. Glick Ph.D Aug 2023

The Water Mills Of The Historic Río Arriba In Northcentral New Mexico, 1598-1975, José A. Rivera Ph.D, Thomas F. Glick Ph.D

Faculty Publications

The water mills of New Mexico played a major role in the agricultural economy of the Río Arriba for centuries following the introduction of wheat from the Old World to the Americas. Wheat, in its ground form as flour, was a staple during the Spanish colonial period. To process raw wheat, local grist mills (molinos) were essential infrastructure as were the aceq uias (ditches) that powered them. Situated near the banks of rivers, the internal components of each mill were driven by the gravity force of water from an acequia, itself diverted from the river. Researchers have documented …


Gender (In)Equity In Global Mental Health Research: A Call To Action, The Women In Global Mental Health Research Group, Kelly Rose-Clarke Jul 2023

Gender (In)Equity In Global Mental Health Research: A Call To Action, The Women In Global Mental Health Research Group, Kelly Rose-Clarke

Faculty Publications

In this commentary, we build on work by Gurung and colleagues which highlighted gender inequity in the global mental health research workforce in Nepal (Gurung et al., 2021). We seek to increase awareness of the under-representation of women in global mental health research and its consequences, and we call for change. By women, we refer to all people who identify as women, including trans people. The commentary is informed by conversations with women who are global mental health researchers in the Global North and South at various stages of their careers.


Investigating The Migratory Behavior Of Soybean Looper, A Major Pest Of Soybean, Through Comparisons With The Corn Pest Fall Armyworm Using Mitochondrial Haplotypes And A Sex-Linked Marker, Rodney N.

Nagoshi, Jeffrey A. Davis, Robert L. Meagher, Fred R. Musser, Graham P. Head, Hector Portillo, Henry Teran

Faculty Publications

The Noctuid moth soybean looper (SBL), Chrysodeixis includens (Walker), is an economically important pest of soybean (Glycine max (Linnaeus) Merrill). Because it is not known to survive freezing winters, permanent populations in the United States are believed to be limited to the southern regions of Texas and Florida, yet its geographical range of infestations annually extend to Canada. This indicates annual migrations of thousands of kilometers during the spring and summer growing season. This behavior is like that of the fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), also a Noctuid that is a major global pest of corn. SBL and …

Faculty Publications

Soil conservation is of global importance, as accelerated soil erosion by human activity is a primary threat to ecosystem viability. However, the significance and role of soil conservation in reshaping landscape carbon (C) accounting has not been comprehensively integrated in the terrestrial C sink. Here, we present the first integrated assessment of the modified terrestrial C sink and aquatic C transport due to soil conservation for the semiarid Chinese Loess Plateau (CLP), the world's most vulnerable region to soil erosion. We show a surprisingly low terrestrial-aquatic C transfer that offset the terrestrial net ecosystem productivity by only 7.5%, which we …

Faculty Publications

Equity in health care delivery is a longstanding concern of public health policy. Telehealth is considered an important way to level the playing field by broadening health services access and improving quality of care and health outcomes. This study refines the recently developed “2-Step Virtual Catchment Area (2SVCA) method” to assess the telehealth accessibility of primary care in the Baton Rouge Metropolitan Statistical Area, Louisiana. The result is compared to that of spatial accessibility via physical visits to care providers based on the popular 2-Step Floating Catchment Area (2SFCA) method. The study shows that both spatial and telehealth accessibilities decline …


Domain Restriction Zones: An Evolution Of The Military Exclusion Zone, Cole M. Mooty, Robert A. Bettinger, Mark G. Reith Jul 2023

Domain Restriction Zones: An Evolution Of The Military Exclusion Zone, Cole M. Mooty, Robert A. Bettinger, Mark G. Reith

Faculty Publications

Since the early part of the twenty-first century, US adversaries have expanded their military capabilities within and their access to new warfighting domains. When faced with the growth of adversaries’ asymmetric capabilities, the means, tactics, and strategies previously used by the US military lose their proportional effectiveness. To avoid such degradation of capability, the operational concept of the military exclusion zone (MEZ) should be revised to suit the modern battlespace while also addressing the shifts in national policy that encourage diplomacy over military force. The concept and development of domain restriction zones (DRZs) increase the relevancy of traditional MEZs in …

Recurrent outbreaks of zoonotic infectious diseases highlight the importance of considering the interconnections between human, animal, and environmental health in disease prevention and control. This has given rise to the concept of One Health, which recognizes the interconnectedness of between human and animal health within their ecosystems. As a contribution to the One Health approach, this study aims to develop an indicator system to model the facilitation of the spread of zoonotic diseases. Initially, a literature review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement to identify relevant indicators related to One Health.

In The Ceo We Trust: Negative Effects Of Trust Between The Board And The Ceo, Kee-Hong Bae, Sadok El Ghoul, Zhaoran (Jason) Gong, Omrane Guedhami Jun 2023

In The Ceo We Trust: Negative Effects Of Trust Between The Board And The Ceo, Kee-Hong Bae, Sadok El Ghoul, Zhaoran (Jason) Gong, Omrane Guedhami

Faculty Publications

In this study, we investigate whether and how trust between board members and the CEO (board–CEO trust) affects the performance of mergers and acquisitions. Contrary to conventional wisdom, we find that firms with higher levels of board–CEO trust exhibit poor M&A performance. High trust is associated with low acquisition announcement returns, long-term stock return performance, and post-deal operating performance. This negative effect of board–CEO trust is more pronounced among acquiring companies prone to agency problems. Our results suggest that, in the institutional setting of corporate boards, high trust can be too much of a good thing.

Faculty Publications

The discourse on vulnerability to COVID-19 or any other pandemic is about the susceptibility to the effects of disease outbreaks. Over time, vulnerability has been assessed through various indices calculated using a confluence of societal factors. However, categorising Arctic communities, without considering their socioeconomic, cultural and demographic uniqueness, into the high and low continuum of vulnerability using universal indicators will undoubtedly result in the underestimation of the communities' capacity to withstand and recover from pandemic exposure. By recognising vulnerability and resilience as two separate but interrelated dimensions, this study reviews the Arctic communities' ability to cope with pandemic risks. In …

Reduction in river discharge and sediment load has left deltaic lobes in the world’s many river deltas starving, but knowledge of how the subaqueous topography of these abandoned subdeltas responds to environmental changes is limited. In this study, we aimed to determine the long-term dynamics of the subaqueous seabed of abandoned delta lobes to advance current knowledge. As a case study, we selected an abandoned subdelta on the Yellow River Delta of the Bohai Sea, China, for which three-decade long (1984–2017) bathymetric data and long-term river discharge and sediment load records are available. We analyzed the seafloor surface change and …

Available soil moisture is thought to be the limiting factor for most ecosystem processes in the cold polar desert of the McMurdo Dry Valleys (MDVs) of Antarctica. Previous studies have shown that microfauna throughout the MDVs are capable of biological activity when sufficient soil moisture is available (~2–10% gravimetric water content), but few studies have attempted to quantify the distribution, abundance, and frequency of soil moisture on scales beyond that of traditional field work or local field investigations. In this study, we present our work to quantify the soil moisture content of soils throughout the Fryxell basin using multispectral satellite …

Contrasting Responses Of Atlantic And Pacific Tropical Cyclone Activity To Atlantic Multidecadal Variability, Huanping Huang, William D. Collins, Christina M. Patricola, Yohan Ruprich-Robert, Paul A. Ullrich, Alexander J. Baker

Faculty Publications

This research assesses the influences of Atlantic Multidecadal Variability (AMV) on global tropical cyclones (TCs) using two large ensembles of idealized global climate model simulations with opposite signs of AMV forcings superimposed (i.e., AMV+ and AMV–). We first detect TCs and then compare TC activity by basin in the two AMV experiments. We find contrasting responses of Atlantic and Pacific TC frequency to the AMV anomalies. Compared to AMV–, AMV+ significantly increases TC frequency in the North Atlantic, including those making landfalls. The increase is explained by warmer sea surface temperature, higher relative humidity, increased relative vorticity, and weaker vertical …

The response of the hydrological cycle to anthropogenic climate change, especially across the tropical oceans, remains poorly understood due to the scarcity of long instrumental temperature and hydrological records. Massive shallow-water corals are ideally suited to reconstructing past oceanic variability as they are widely distributed across the tropics, rapidly deposit calcium carbonate skeletons that continuously record ambient environmental conditions, and can be sampled at monthly to annual resolution. Climate reconstructions based on corals primarily use the stable oxygen isotope composition (δ18O), which acts as a proxy for sea surface temperature (SST), and the oxygen isotope composition of seawater (δ18Osw), a …

Soils store more carbon than other terrestrial ecosystems1,2. How soil organic carbon (SOC) forms and persists remains uncertain1,3, which makes it challenging to understand how it will respond to climatic change3,4. It has been suggested that soil microorganisms play an important role in SOC formation, preservation and loss5,6,7. Although microorganisms affect the accumulation and loss of soil organic matter through many pathways4,6,8,9,10,11, microbial carbon use efficiency (CUE) is an integrative metric that can capture the balance of these processes12,13. Although CUE has the potential to act as a predictor of variation in SOC storage, the role of CUE in SOC …

This chapter is shared with express permission of Bloomsbury Academic. The full book is available at: https://www.bloomsbury.com/us/access-to-justice-in-rural-communities-9781509951642/ The justice gap persists in many rural parts of the world due to a confluence of economic, cultural, and professional factors at play throughout the justice system and society at large. This justice gap means that people in rural areas experience institutions of justice – including access to lawyers and other legal advice – differently than people in urban areas. Travel, distance, the rural lawyer shortage, and other factors create this difference. No single factor or institution can be blamed for the rural …

What, how and why people eat has long been understood to be important for human health, but until recently, has not been recognised as an essential facet of climate change and its effects on planetary health. The global climate change and diet-related health crises occurring are connected to food systems, food environments and consumer food choices. Calls to transform food systems for human and planetary health highlight the importance of understanding individual food choice. Understanding what, how and why people eat the way they do is crucial to successful food systems transformations that achieve both human and planetary health goals. …


Latino Paradox Or Black Exception? Race, Ethnicity, And Crime In The 21st Century, Edward S. Shihadeh, Raymond E. Barranco May 2023

Latino Paradox Or Black Exception? Race, Ethnicity, And Crime In The 21st Century, Edward S. Shihadeh, Raymond E. Barranco

Faculty Publications

George Floyd’s murder by a Minnesota police officer sparked outrage, protests, and a re-evaluation of racial inequities in America. Within criminology, we argue, that re-evaluation should include the Latino Paradox, the idea that Latino communities are an exception—a paradox—in that, while they face economic deprivation, they also possess a magical something that makes them resistant to social problems like crime. Unfortunately, this compels the more delicate question; what is the deficiency in Black communities that makes them so vulnerable to crime? However, as we argue here, the Latino Paradox forces a false comparison. Its assumptions with respect to crime are …

The atmospheric density of the thermosphere is a fundamental parameter for spacecraft launch and orbit control. Under magnetic storm conditions, the thermospheric atmospheric density experiences significant fluctuations, which have a negative impact on spacecraft control. Exploring thermospheric density during geomagnetic storms can help to mitigate the effects of such events. Research on the inversion of accelerometer measurements for different satellites and the variations of atmospheric density under extreme conditions is still in its infancy. In this paper, the distribution of atmospheric density during three geomagnetic storms is investigated from the inversion results of the Swarm-C accelerometer. Three major geomagnetic storms …

Rapid retreat of Antarctic ice shelves in a warmer climate remains challenging to predict, contributing to uncertainties in projections of sea level rise. The collapse of the Larsen B Ice Shelf on the Antarctic Peninsula in 2002 was perhaps the most dramatic example of ice shelf retreat on record. Despite a general consensus that regional climate warming is associated with ice shelf collapse, knowledge of the precise details leading to and following collapse is limited. Here we examine a comprehensive set of satellite observations, modeling experiments, and climate reanalysis data to elucidate calving behavior, flow dynamics, and mechanical conditions of …

This Essay formalizes the concept of governance seams and develops theories for what they enable; how they arise; why they are some- times dismantled; and how, why, and when regulators might step in to protect endangered governance seams or to create new ones. Governance seams are socially constructed boundaries, borders, and interfaces that harness friction-in-design to enable governance. Governance seams mediate interactions among components of sociotechnical systems and between different parties and contexts. Delineating boundaries, borders, and interfaces as loci of transparency, coordination, and oversight supports mechanisms for deliberation, contestation, and protection, both by those within and those outside the …

The Clinic As A Site Of Grounded Pedagogy, Madalyn K. Wasilczuk

Faculty Publications

Legal education tends to focus on teaching students federal law from hefty casebooks, inculcating the ability to "think like lawyers." In a sea of Socratic lectures and hypotheticals, students often take refuge in clinics as an island of practical skills-building, client centeredness, and individual fulfillment. Yet even clinics sometimes fail to highlight for students how the place where they practice, with its particular political context and history, shapes their clients' lives and legal problems. This Article describes the law school clinic as a site of grounded pedagogy: a teaching method that centers the con­nection between local history and the present …

The proposed Anthropocene Global Boundary Stratotype Section and Point (GSSP) candidate site of West Flower Garden Bank (27.8762°N, 93.8147°W) is an open ocean location in the Gulf of Mexico with a submerged coral reef and few direct human impacts. Corals contain highly accurate and precise (<±1 year) internal chronologies, similar to tree rings, and their exoskeletons are formed of aragonite and can be preserved in the rock record. Here we present results from a large Siderastrea siderea coral (core 05WFGB3; 1755–2005 CE) sampled with annual and monthly resolutions that show clear markers of global and regional human impacts. Atmospheric nuclear bomb testing by-products (14C, 239+240Pu) have clear increases in this coral starting in 1957 for 14C and the first increase in 1956 for 239+240Pu (potential bases for the Anthropocene GSSP). Coral δ13C declined especially after 1956 consistent with the Suess effect resulting from the burning of fossil fuels. Coral skeletal δ15N starts to increase in 1963 corresponding with the increase in agricultural fertilizers. Coral Hg concentrations (1933–1980) loosely track fluctuations in industrial pollution and coral Ba/Ca increases from 1965–1983 when offshore oil operations expand after 1947. Coral temperature proxies contain the 20th-century global warming trend whereas coral growth declines during this interval.

Corals are unique in the suite of proposed Anthropocene Global Boundary Stratotype Section and Point (GSSP) archives, as living organisms that produce aragonite exoskeletons preserved in the geological record that contain highly accurate and precise (<±1 year) internal chronologies. The GSSP candidate site North Flinders Reef in the Coral Sea (Australia) is an offshore oceanic reef, and therefore less vulnerable to local human influences than those closer to the coast. Here, we present geochemical records from two Porites sp. corals sampled at an annual to pluri-annual (i.e. 3–5 years) resolution that shows clear global and regional human impacts. Atmospheric nuclear bomb testing by-products (14C,239+240Pu) show a clear increase in the Flinders Reef corals coincident with well-dated nuclear testing operations. By contrast, the radionuclides 241Am and 137Cs are present at low or undetectable levels, as are spheroidal carbonaceous fly-ash particles. Coral δ13C shows centennial variability likely influenced by growth effects in the 18th century and with a progression to lower values starting in 1880 CE and accelerating post-1970 CE. The latter may be related to the Suess effect resulting from 13C-depleted fossil fuel burning. Coral δ15N decreased between 1710 and 1954 CE with a reversal post-1954 CE. Coral temperature proxies indicate prominent centennial variability with equally warm conditions in the 18th and end of 20th century. However, the exact mechanisms responsible for the mid-20th century changes in these parameters need to be scrutinised in further detail. Plain Language summary: This work proposes a candidate natural archive for the official marker of the Anthropocene that geologists will use to mark this important interval in time. Our candidate is a live coral from North Flinders Reef in the Coral Sea (Australia), located 150 km east of the Great Barrier Reef, a location that is remote from direct local human influences. Corals are a unique archive of tropical ocean change because they incorporate the geochemical signature from seawater into their limestone skeleton during their long life-spans. Here we investigated a number of geochemical markers in yearly growth layers of the corals to define several markers for the Anthropocene based on changes in temperature, water chemistry, chemicals from pollution and fertilisers, radioactive products from nuclear bomb testing, and by-products from burning fossil fuels. We have detected clear human influences in several of these markers.
