The State of Outdoor Recreation in Utah 2020
The purpose of this report is to provide a high-level review of the trends that define outdoor recreation within Utah. We do this by distilling data from a variety of sources, focusing on âkey metricsâ that can be tracked over time, serving as a finger on the pulse on the health of outdoor recreation within Utah. Data on outdoor recreation participation and its benefits and impacts varies considerably across the state depending upon the managing agency collecting the data. This report focuses on statewide data available for outdoor recreation opportunities provided on lands managed by the Bureau of Land Management, National Park Service, US Fish and Wildlife Service, USDA Forest Service, and Utah State Parks. We highlight data unique to administrative units (e.g., national parks or forests) where applicable. The report focuses on four sets of key metrics: 1) Participation; 2) Economics; 3) Infrastructure; and 4) Gateway and Natural Amenity Region (GNAR) communities
Interfaces in driven Ising models: shear enhances confinement
We use a phase-separated driven two-dimensional Ising lattice gas to study
fluid interfaces exposed to shear flow parallel to the interface. The interface
is stabilized by two parallel walls with opposing surface fields and a driving
field parallel to the walls is applied which (i) either acts locally at the
walls or (ii) varies linearly with distance across the strip. Using computer
simulations with Kawasaki dynamics, we find that the system reaches a steady
state in which the magnetisation profile is the same as that in equilibrium,
but with a rescaled length implying a reduction of the interfacial width. An
analogous effect was recently observed in sheared phase-separated colloidal
dispersions. Pair correlation functions along the interface decay more rapidly
with distance under drive than in equilibrium and for cases of weak drive can
be rescaled to the equilibrium result.Comment: 4 pages, 3 figures Text modified, added Fig. 3b. To appear in Phys.

A specific deficit of auditory processing in children with Rolandic Epilepsy and their relatives
Previous research shows that children with Rolandic Epilepsy have deficits of auditory processing. We wanted to confirm the nature of this deficit and whether it aggregates in families. We compared 40 children with Rolandic Epilepsy and 32 unaffected siblings with 99 typically developing children and 71 parents of RE children with 31 healthy adults on a battery of auditory processing tests. We also examined ear advantage in children with RE, their siblings and parents using population norms and measured non-word reading performance. We found a specific deficit for competing words in patients, their siblings and their parents, suggesting that this particular impairment of auditory processing present in children with RE, is heritable and likely to be persistent. Importantly, scores on this subtest in patients and siblings were significantly correlated with non-word reading performance. We saw increased rates of atypical left ear advantage in patients and siblings but no evidence of this in parents. We present these findings as evidence of familial incidence of dichotic listening and ear advantage abnormalities in relatives of children with Rolandic Epilepsy
Bears Ears and Outdoor Recreation in San Juan County
The creation and subsequent downsizing of Bears Ears National Monument has been one of the most publicized and politicized land management decisions within the state over the past decade. However, relatively little research has been conducted to determine if, and to what extent, the creation of the monument impacted outdoor recreation and recreation-related industries. Now, more than three years after the monument was created, there are sufficient data to take a retrospective look at the influence of the monument. The purpose of this research is to evaluate the influence of Bears Ears National Monument on outdoor recreation and its related industries in San Juan County, Utah
What is known about tobacco industry efforts to influence tobacco tax? A systematic review of empirical studies.
OBJECTIVE: To systematically review studies of tobacco industry efforts to influence tobacco tax policies. METHODS: Searches were conducted between 1 October 2009 and 31 March 2010 in 14 databases/websites, in relevant bibliographies and via experts. Studies were included if they focused on industry efforts to influence tobacco tax policies, drew on empirical evidence, were in English and concerned the period 1985-2010. In total, 36 studies met these criteria. Two reviewers undertook data extraction and critical appraisal. A random selection of 15 studies (42%) was subject to second review. Evidence was assessed thematically to identify distinct tobacco industry aims, arguments and tactics. RESULTS: A total of 34 studies examined industry efforts to influence tax levels. They suggest the tobacco industry works hard to prevent significant increases and particularly dislikes taxes 'earmarked' for tobacco control. Key arguments to counter increases are that tobacco taxes are socially regressive, unfair and lead to increased levels of illicit trade and negative economic impacts. For earmarked taxes, the industry also frequently tries to raise concerns about revenue allocation. Assessing industry arguments against established evidence demonstrates most are unsupported. Key industry tactics include: establishing 'front groups', securing credible allies, direct lobbying and publicity campaigns. Only seven studies examined efforts to influence tax structures. They suggest company preferences vary and tactics centre on direct lobbying. CONCLUSIONS: The tobacco industry has historically tried to keep tobacco taxes low using consistent tactics and misleading arguments. Further research is required to explore efforts to influence tax structures, excise policies beyond the USA and recent policies
An Assessment of the Location of the Bears Ears National Monument Cultural Center
A cultural center at Bears Ears National Monument, if well planned, could serve as an anchor destination through which visitors could learn about, experience, and appreciate the cultures, histories, and landscapes that define southeastern Utah. A cultural center also holds the potential to bolster the regional economy, by signaling a long-term investment in the sustainability of the regionâs outdoor recreation and tourism industry. Our intent with this analysis is to establish a foundational understanding of potential locations for a cultural center. We develop and analyze a set of cultural, environmental, and economic metrics that can be used to shape ongoing discussions about the potential locations for the Bears Ears National Monument cultural center. Our analysis shows markedly different potential siting locations depending upon whether cultural, environmental, or economic considerations are given priority. When all three considerations are equally weighed, there are several notable âhot spotsâ near Bluff, south and west of Blanding, and west of Monticello. We describe the advantages and disadvantages associated with each of these potential locations. Ultimately, we hope the work we have completed here can be used to shape ongoing discussions about the potential locations for the Bears Ears National Monument cultural center

Outdoor Recreation Use and Indicators of the Ecological, Physical, and Social Characteristics of Recreation Settings in the Central Wasatch: Phase 1 Interim Report
The purpose of this study is to explore how outdoor recreation use and its associated impacts can be quantified and monitored over time within the canyons. Establishing indicators of the ecological, physical, and social characteristics of recreation settings throughout the canyons is an essential first step to quantifying and monitoring change. Our goal is to establish a set of indicators that are collaboratively generated and grounded in the best-available science and reflect the unique needs and concerns of the diverse stakeholders and interest groups who use, manage, and depend on the canyons. Through the work detailed below, the Central Wasatch Commission, the State of Utah, and the Uinta-Wasatch-Cache National Forest will gain a clear understanding of what data on outdoor recreation use currently exist and what data are essential to understand the ecological, physical, and social characteristics of recreation settings
Contrasting roles for DNA methyltransferases and histone deacetylases in single-item and associative recognition memory
Recognition memory enables us to judge whether we have encountered a stimulus before and to recall associated information, including where the stimulus was encountered. The perirhinal cortex (PRh) is required for judgment of stimulus familiarity, while hippocampus (HPC) and medial prefrontal cortex (mPFC) are additionally involved when spatial information associated with a stimulus needs to be remembered. While gene expression is known to be essential for the consolidation of long-term recognition memory, the underlying regulatory mechanisms are not fully understood. Here we investigated the roles of two epigenetic mechanisms, DNA methylation and histone deacetylation, in recognition memory. Infusion of DNA methyltransferase inhibitors into PRh impaired performance in novel object recognition and object-in-place tasks while infusions into HPC or mPFC impaired object-in-place performance only. In contrast, inhibition of histone deacetylases in PRh, but not mPFC, enhanced recognition memory. These results support the emerging role of epigenetic processes in learning and memory
Reduced-folate carrier (RFC) is expressed in placenta and yolk sac, as well as in cells of the developing forebrain, hindbrain, neural tube, craniofacial region, eye, limb buds and heart
BACKGROUND: Folate is essential for cellular proliferation and tissue regeneration. As mammalian cells cannot synthesize folates de novo, tightly regulated cellular uptake processes have evolved to sustain sufficient levels of intracellular tetrahydrofolate cofactors to support biosynthesis of purines, pyrimidines, and some amino acids (serine, methionine). Though reduced-folate carrier (RFC) is one of the major proteins mediating folate transport, knowledge of the developmental expression of RFC is lacking. We utilized in situ hybridization and immunolocalization to determine the developmental distribution of RFC message and protein, respectively. RESULTS: In the mouse, RFC transcripts and protein are expressed in the E10.0 placenta and yolk sac. In the E9.0 to E11.5 mouse embryo RFC is widely detectable, with intense signal localized to cell populations in the neural tube, craniofacial region, limb buds and heart. During early development, RFC is expressed throughout the eye, but by E12.5, RFC protein becomes localized to the retinal pigment epithelium (RPE). CONCLUSIONS: Clinical studies show a statistical decrease in the number of neural tube defects, craniofacial abnormalities, cardiovascular defects and limb abnormalities detected in offspring of female patients given supplementary folate during pregnancy. The mechanism, however, by which folate supplementation ameliorates the occurrence of developmental defects is unclear. The present work demonstrates that RFC is present in placenta and yolk sac and provides the first evidence that it is expressed in the neural tube, craniofacial region, limb buds and heart during organogenesis. These findings suggest that rapidly dividing cells in the developing neural tube, craniofacial region, limb buds and heart may be particularly susceptible to folate deficiency
