Heritage Values And Community Perception : A Look Into The Historic Ruins Of Dinajpur Rajbari, Murchana Madhury, Labanya Sarker

NAKHARA (Journal of Environmental Design and Planning)

The establishment of the value and effective protection of historical ruins comprises a subject of rising interest, as evidenced by an increasing amount of research involving several disciplines. In Bangladesh, debates on the relevance of such abandoned, degraded, deformed, or empty structures—unlike other intact monuments in heritage studies—rarely take into account the attitude of the locals towards these ruins. Analyzing the case of Dinajpur Rajbari, Bangladesh, the paper intends to explore the value ascribed to historic ruins by the surrounding community. The study uses a case study approach built on Mason’s value typology, which has widely contributed to the identification …

Lithium And Water: Hydrosocial Impacts Across The Life Cycle Of Energy Storage, James J.A. Blair, Noel Vineyard, Dustin Mulvaney, Alida Cantor, Ali Sharbat, Kate Berry, Elizabeth Bartholomew, Ariana Firebaugh Ornelas

Faculty Research, Scholarly, and Creative Activity

As a key ingredient of batteries for electric vehicles (EVs), lithium plays a significant role in climate change mitigation, but lithium has considerable impacts on water and society across its life cycle. Upstream extraction methods—including open-pit mining, brine evaporation, and novel direct lithium extraction (DLE)—and downstream processes present different impacts on both the quantity and quality of water resources, leading to water depletion and contamination. Regarding upstream extraction, it is critical for a comprehensive assessment of lithium's life cycle to include cumulative impacts related not only to freshwater, but also mineralized or saline groundwater, also known as brine. Legal frameworks …

Opening The Black Box: Carbon-Footprint Calculators, Meat Consumption, And The “Wicked Problem” Of Metric Governance, E. Melanie Dupuis, Dustin Mulvaney

Faculty Research, Scholarly, and Creative Activity

Carbon-footprint calculators are widely used as communication and education tools, designed to make people aware of the ways their personal actions contribute to greenhouse-gas emissions. However, they have come under criticism for emphasizing individual behavior versus structural change. We extend this critique to argue that carbon-footprint calculators are a form of “metric governance” that not only disciplines users but also constrains their abilities to engage with the complexities of climate change and social action. We focus on a particularly wicked problem of carbon-metric governance: livestock greenhouse-gas emissions. We show that carbon-footprint calculators black box and fix the complex politics and …

Just Look At The Map: Bounding Environmental Review Of Housing Development In California, Eric Biber, Christopher S. Elmendorf, Nicholas Marantz, Moira O’Neill

Faculty Scholarship

California faces a dire housing crisis. California’s land-use regulatory system remains a key driver of this crisis. State law grants local governments broad power to craft their own regulations on how to review and approve housing development. Though state law may limit a locality’s ability to outright deny some types of housing development, local governments can and do use creative ways to stall approvals or functionally deny housing by making it infeasible to develop. One such strategy is to demand more intensive environmental review of new housing projects under the California Environmental Quality Act (CEQA) than what state law requires. …

School of Geography, Earth and Environmental Sciences

The atmosphere plays a critical role in the regional and global transportation and redistribution of microplastics (MPs). However, the significance of rainfall and its means of scavenging MPs are not well understood. In this study, MP deposition was determined during successive dry and rainy events over eight consecutive days in the Shiraz region of Iran. Flux magnitudes and temporal distributions at six sites within and outside the city (including a remote, non-urbanised location) were similar and revealed a progressive increase in MP abundance and deposition during dry periods (up to about 50 MP m−2 h−1) and subsequent relatively rapid wet …

Fostering Entry Level Practitioner Knowledge, Confidence, And Competence In Trauma-Informed Care Application, Mollie Keyser, Mary A. Barnes

Journal of Occupational Therapy Education

Trauma is pervasive worldwide and is associated with poor health outcomes if left unaddressed, however, a gap in practice continues to exist in the implementation of trauma-informed care (TIC). Occupational therapy practitioners will encounter individuals, communities, and populations influenced by trauma, which warrants the need for TIC to improve overall service delivery across the lifespan. However, TIC is currently not systematically integrated into any Accreditation Council for Occupational Therapy Education (ACOTE) occupational therapy educational standards. The purpose of this study was to design, implement, and evaluate a TIC application-based workshop for a sample of entry-level occupational therapy doctorate (OTD) students. …

Evaluating Efficiency And Accuracy Of Three Texture Analysis Methods For Blackberry Fruit, Rhys M. Brock, Carmen Johns, Katelyn Lust-Moore, Margaret Worthington

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

A major objective of the University of Arkansas System Division of Agriculture (UADA) Fruit Breeding program is to improve the texture of blackberry (Rubus subgenus Rubus Watson). Blackberry varieties with improved fruit firmness transport and store well and may maintain superior quality under challenging postharvest conditions than softer varieties. Increased firmness may also make cultivars less susceptible to red drupelet reversion (RDR), a postharvest disorder of blackberries in which fully black drupelets revert to red after harvest. This research project aims to assess the efficiency and accuracy of three methods applied in evaluating blackberry firmness. The study compares instrumental analysis …

Understanding The Impact Of Food Insecurity Among First-Generation College Students On The University Of Arkansas Campus, Madison Price, Jennie S. Popp Ph.D., Nathan Paul Kemper, Louise Michelle Hancox

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The purpose of this study was to: 1) better understand food insecurity among first-generation college students and how it might differ from that of other college students, and 2) gather opinions from students that may serve as solutions to alleviate food insecurity. This study was conducted with a mixed-methods survey that included both open-ended and closed-ended questions. This survey had 670 responses. Nearly 10% of respondents stated that they were experiencing food insecurity. Almost 18% stated they were first-generation college students. A greater percentage of African American (P = 0.0022) and Hispanic Latino (P < 0.0001) students were first-generation compared to all other students, while a lower percentage (P < 0.0001) of Caucasian students were first-generation compared to other students. The results suggested that first-generation students were more likely to experience nine food insecurity impacts than non first-generation students. Further, both first-generation and non first-generation students indicated low levels of knowledge and/or use of existing resources on the University of Arkansas campus that can help address food insecurity needs. Finally, both first-generation and non first-generation respondents overwhelmingly favored food insecurity solutions centered around expanding access to campus food programs through lower costs and increased awareness of existing campus resources via improved advertising.

Stream Restoration Effectiveness In Mullins Creek In Fayetteville, Arkansas, Amadeo Scott, Shannon Speir

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Lotic waterways are vital for habitat, food, water, and flood protection, but urbanization poses a major threat to their integrity. Runoff from urban surfaces leads to pollution, flashiness, loss of biodiversity, and other symptoms, also known as Urban Stream Syndrome (USS). Streams can be restored in order to combat USS, but most restorations are not monitored, so their long-term effectiveness is unknown. This study quantitatively evaluated a decade-old stream restoration in Fayetteville, Arkansas, to assess its effectiveness in combating USS and achieving set restoration goals, and to gain insights for future restoration projects. Restoration goals included decreasing erosion and sedimentation, …

A Rare Leadership Journey: Exploring Perspectives Of Women In Construction, Taylor M. Krueger

Doctor of Business Administration (DBA)

This qualitative study examined the lived experiences of female leaders in the U.S. construction industry. A narrative method and methodology was used incorporating Mezirow’s (1978) transformative learning, Super’s (1957) career development, and Cooperrider et al. 's (2008) appreciative inquiry theories. The primary research question: How do women currently leading at their respective construction firms make meaning of their leadership development experiences? Eight interpretations emerged. First, leadership development experiences occur in non-formal settings, since childhood, and rarely follow a linear path. Second, company culture or the perspective and bias of upper management strongly dictate the opportunities and occurrences of female employment, …

Climate Risk, Insurance Retreat, And State Response, Mark P. Nevitt, Michael Pappas

Faculty Articles

Climate change is fundamentally destabilizing the private insurance industry, with many high-profile insurance companies exiting states in the face of catastrophic, climate-­induced risk. This rapid "insurance retreat" represents a major market signal in response to climate-exacerbated risks. Private businesses are making actuarial decisions, assessing that some locations are just too vulnerable to insure. At the same time, this insurance retreat also poses a policy challenge for states as they react to the mounting insurance gaps left by exiting private insurers.

This Article analyzes insurance retreat, its attendant policy challenges, and the lessons that can be drawn from state responses. It …

Noncoding DNA is central to our understanding of human gene regulation and complex diseases1,2, and measuring the evolutionary sequence constraint can establish the functional relevance of putative regulatory elements in the human genome3–9. Identifying the genomic elements that have become constrained specifically in primates has been hampered by the faster evolution of noncoding DNA compared to protein-coding DNA10, the relatively short timescales separating primate species11, and the previously limited availability of whole-genome sequences12. Here we construct a whole-genome alignment of 239 species, representing nearly half of …
