Evaluating the pandemic’s impact on speeding-related injury severity on Oregon’s rural roads: a mixed logit analysis with temporal constraints

During the COVID-19 pandemic, Oregon experienced fewer crashes and a 10.77% decline in vehicle miles traveled, yet fatal crashes increased. This study examines factors influencing injury severity in speeding-related single-vehicle passenger car crashes on rural Oregon roads and t...

Bi-Parental Mapping and Validation of Barley Yellow Dwarf Virus Resistance Locus in Barley Cultivar ‘Lightning’

Barley Yellow Dwarf Virus (BYDV), caused by multiple viruses within the Luteoviridae family and primarily transmitted by aphids, is among the most economically significant viral diseases impacting barley (Hordeum vulgare subsp. vulgare) production worldwide, resulting in stunted...

Disability Representation in Social and Personality Psychology Research: A State-of-the-Art Review

We conducted a systematic state-of-the-art review examining disability representation of three flagship social and personality psychology journals between 2017 and 2022. First, we examined the 2,343 articles published in that time frame and found that 192 (8.19%) of them used at...

A mixed-scale hardware-in-the-loop testing framework for wave energy converter-autonomous underwater vehicle systems

Hardware-in-the-Loop (HIL) offers a promising pathway for evaluating wave energy converter–autonomous underwater vehicle (WEC–AUV) systems in the laboratory, where a mix of laboratory-scale waves and full-scale AUVs present significant challenges for conventional testing approach...

Italian Fluvial Sediment Transport Database: a comprehensive hub for archiving and analyzing hydrological data

Fluvial sediment transport plays a key role in geomorphological and hydrological processes, influencing river morphology, watershed and coastal sediment balances, and the environmental response to climatic and anthropogenic changes. In Italy, the availability of homogeneous and l...

Open Ocean Biogeochemical Impacts of Extreme Terrestrial Precipitation

Abstract Extreme events reshape ocean ecosystems with significant implications for nutrient and carbon cycling. Here, we demonstrate that flooding on land can be a significant driver of biogeochemical variability in the open ocean, even in relatively dry climates. Using satellite...

Propagation of plot location uncertainty through unit-level small area estimation in operational forest inventory

Contemporary sources of remotely sensed data (e.g. Sentinel-2, LiDAR) invite reconsideration of forest cruising methodology through model-based estimation such as small area estimation (SAE). The unit-level nested error regression model is attractive because it exploits fine-grai...

Past rapid spread of introduced livestock coincided with vegetation clearance on Madagascar

Debates persist around the past and present effects of introduced livestock on the native biodiversity of Madagascar. Indeed, the variable habitat and past rate of spread of livestock across the island's distinct ecoregions are poorly known. Sets of 14C and stable isotope data fr...

Pb(II) Selectivity of Oxygen-Functionalized Lignite-Based Carbon Material in the Presence of Competitive Cu(II)/Cd(II) Interference

Abstract A series of lignite-derived activated carbons (CK-400-CK-700) was prepared by KOH activation to clarify the effects of pore structure and surface oxygen functionality on Pb(II) adsorption. Although the BET surface area increased from 456.60 to 1300.70 m2·g–1 with activat...

Polycyclic aromatic hydrocarbons, gut microbiome composition, impulsivity, and attention covary in a human cohort

ABSTRACT Polycyclic aromatic hydrocarbons (PAHs) are pervasive environmental pollutants linked to adverse neurobehavioral outcomes, yet the biological pathways coupling exposure to behavior are poorly defined. The gut microbiome is both sensitive to PAH exposure and a modulator o...

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example. Curren...

Behavioral intention to participate in carbon-based forest management: An extension of the theory of planned behavior

Afforestation on marginal lands through carbon-based forest management (CBFM) is a viable approach to sequester carbon and reduce carbon dioxide emissions. The participation of private landowners is essential for CBFM implementation, as most marginal lands in the Southern United...

Policies and practices for sustainable preservation of theses and dissertations in higher education institutes

This study examines the digital preservation landscape for Electronic Theses and Dissertations (ETDs) across global Higher Education Institutions (HEIs). Employing a qualitative, empirical research design, the study utilizes Qualitative Content Analysis (QCA) and Document Analysi...

An Examination of the Influences of Mathematics Anxiety in Middle School Algebra 1 Students

With an increase in the number of students enrolled in Algebra 1 during their middle school years, this explanatory sequential mixed-method study examined how mathematics anxiety influences middle-school Algebra 1 students’ cognitive and metacognitive processes as they complete c...

Shallow Landslides Align With Atmospheric Rivers in Coastal Steeplands

Abstract Rapid, shallow landslides in coastal mountains are triggered by extreme precipitation, shaping topography and impacting human settlements. Using an inventory of >700 landslides mapped from satellite imagery (2009–2024) and an atmospheric river database (1981–2019), this...

Understanding STEM Coursetaking Among English Learner Subgroups: Longitudinal Evidence From Four State Policy Contexts

Abstract Although a substantial body of research documents the problem of course tracking for students classified as English learners (ELs), very little work has addressed the notably different challenges that subgroups of ELs face across different state policy contexts. This des...

Association of Community Factors, Firearm Laws, and Pediatric Firearm Injuries

OBJECTIVE: To conduct a zip code-level analysis of community measures and firearm legislation associated with pediatric fatal and nonfatal firearm injuries, ordered by strength of association. METHODS: This was an ecological study of 46 states and the District of Columbia from Ja...

Advancing conflict research and response through satellite-derived data

Abstract With armed conflicts at a historic high and attacks on civilians rising 1 , understanding the evolving nature of conflict is a critical research priority. The current paradigm in conflict research relies heavily on text-based data, using fatalities as the primary—and oft...

Resistance to Bean Common Mosaic Virus Conferred by the bc-u Gene Does Not Affect Replication or Systemic Spread of the Virus in Common Bean but Ameliorates the Strain-Specific Systemic Necrosis

Resistance to bean common mosaic virus (BCMV) in common bean is governed by four strain-specific, recessive (bc-u, bc-1, bc-2, and bc-3) and one strain non-specific, dominant (I) genes. BCMV exists as a complex of strains defined biologically based on host range and on their mole...
