On piñon-juniper encroached sites that lack the understory fuels to carry a prescribed fire, treatment options are limited to mechanical methods. Cutting with chainsaws and leaving the trees on site has been the primary treatment method for such sites, however this method creates a potential fire hazard, particularly in the...
The expansion of pion-juniper woodlands the past 100 years in the western United States has resulted in large scale efforts to kill trees and recover sagebrush steppe rangelands. It is important to evaluate vegetation recovery following woodland control to develop best management practices. In this study, we compared two fuel...
State-and-transition models (STMs) have been successfully used to
describe ecological dynamics in woodlands, shrublands, grasslands, and several other ecosystems. Changes in vegetation and soil are measured to gauge and predict plant community dynamics within ecological states and transitions between alternative ecological states. Ecological states and their boundaries are defined by...
The purpose of this qualitative research study was to examine the role a rural community college plays in the development of its community, using a holistic, community-based lens that considered college and community context, interactions and results to answer the question: How does the rural community college impact the development...
Flavored milk is a growing category for dairy products; however, it is a perishable product that is subject to microbial spoilage which can lead to a negative consumer experience and lead to lost sales. Flavored milk processors communicated unique spoilage events related to their products, including color loss of strawberry...
Per- and polyfluoroalkyl substances (PFAS) are a group of contaminants of great concern due to their toxicity and ubiquity in the environment. Remediation efforts historically have focused on granular activated carbon (GAC) because of its low maintenance and relatively low cost. However, GAC is not PFAS selective and is especially...
Potentially carcinogenic compounds may cause cancer through direct DNA damage or through indirect cellular or physiological effects. To study possible carcinogens, the fields of endocrinology, genetics, epigenetics, medicine, environmental health, toxicology, pharmacology and oncology must be considered. Disruptive chemicals may also contribute to multiple stages of tumor development through effects...
Design in secondary mathematics teacher education must prepare teacher candidates to do the work of ambitious and equitable mathematics teaching with skill by situating development in the work of teaching and incorporating opportunities to investigate and enact teaching. Teacher education designs must also be responsive to the work that mathematics...
Since underrepresented nominees began filling U.S. Supreme Court seats, political scientists have examined the possibility of existing biases towards potential judges based upon their identities or innate characteristics. Some scholars have identified that the gender identification and ethnic affiliations of candidates have affected the behaviors displayed by those involved in...
The purpose of this study was to describe the leadership development process
of former student leaders at Snow College. More specifically, the study focused on
understanding how, when, and where leadership development took place in their
"lived experience" within the student government at Snow College (Van Manen,
1998). Examining the...

Research indicates that adolescents with a history of parental incarceration are at higher risk of delinquent behaviors (Murray & Farrington, 2005), however the protective role of parent-adolescent relationships is largely unexamined when compared with negative dimensions of parenting. To examine the potential protective effects of the adolescent’s perceptions of a...
Predicting the effects of climate change on ecological communities requires an understanding of how environmental factors influence both physiological processes and species interactions. Specifically, the net impact of temperature on community structure depends on the relative response of physiological energetic costs (metabolism) and energetic gains (ingestion of resources) that mediate...
OBJECTIVE: To identify and rank perceived personal benefits from parenting practices that promote intake of calcium-rich foods and beverages (CRF/B) by early adolescents. METHODS: A convenience sample of parents/caregivers (n = 133) of early adolescents (10-13 years) from 6 states (CA, HI, MN, OH, OR, UT) participated in a qualitative...
A scalable synthesis of the "flat" tridecameric inorganic cluster [Al₁₃(μ₃-OH)₆(μ-OH)₁₈(H₂O)₂₄]¹⁵⁺ has been realized by treating an aqueous aluminum nitrate solution with zinc-metal powder at room temperature. Single crystals and polycrystalline samples are readily obtained in yields exceeding 55% relative to the starting reagent Al(NO₃)₃. Products have been characterized by X-ray...
Nonalcoholic fatty liver disease (NAFLD) has increased in parallel with central obesity and its prevalence is anticipated to increase as the obesity epidemic remains unabated. NAFLD is now the most common cause of chronic liver disease in developed countries and is defined as excessive lipid accumulation in the liver, i.e.,...
The prevalence of non-alcoholic fatty liver disease (NAFLD) has increased in parallel with central obesity and is now the most common chronic liver disease in developed countries. NAFLD is defined as excessive accumulation of lipid in the liver, i.e., hepatosteatosis. The severity of NAFLD ranges from simple fatty liver (steatosis)...
In marine ecosystems, rising atmospheric CO2 and climate change are associated with concurrent shifts in temperature, circulation, stratification, nutrient input, oxygen content, and ocean acidification, with potentially wideranging biological effects. Population-level shifts are occurring because of physiological intolerance to new environments, altered dispersal patterns, and changes in species interactions. Together...
