Advancing Virtual Care Practices Across the Cognitive Impairment ContinuumAs the population of older adults grows, providing high-quality, cost-effective healthcare for those with cognitive impairments is an increasing priority. The COVID-19 pandemic accelerated the shift towards receiving virtual care at home through temporary Medicare flexibilities. However, the uncertainty surrounding the continuing extension of these flexibilities at the federal level and variations in reimbursement policies across the states present challenges for virtual care practices to meet the rising demand for care amid unprecedented workforce shortages. Sustainable, long-term reimbursement at the federal and state levels, a trained and integrated healthcare workforce, and adherence to recognized accreditation standards and guidelines are essential to advance the quality and safety of virtual care for cognitively impaired patients. Furthermore, reimbursement policies that incentivize investments in technology infrastructure and digital literacy outreach are needed to ensure equitable access to virtual care for all patients across the cognitive impairment continuum.

Perfiles de Economía Agrícola de los Condados de ArizonaEsta serie de perfiles de condados presenta la producción agrícola, el uso del agua y los datos económicos regionales en un formato estandarizado, integrado y fácil de leer para brindar contexto sobre el papel de la agricultura dentro de las economías estatales y de los condados, así como su papel como administrador de tierras y recursos naturales. Los perfiles están disponibles en Inglés y Español. El Programa de Extensión de Análisis Económico Regional (EREAP, por sus siglas en inglés) lleva a cabo investigaciones aplicadas y análisis económicos que abordan temas de desarrollo económico alrededor de Arizona. Trabajamos para satisfacer las necesidades del sistema de Extensión Cooperativa y de las personas beneficiarias del mismo, tales como personas pertenecientes a las industrias agrícolas y agroindustriales de Arizona, los usuarios y organizaciones relacionadas al uso de recursos naturales, y grupos de economía regional, para proporcionar análisis especializados e información específica.

ECONOMIC CONTRIBUTION & IMPACTS OF ARIZONA’S STATE PARKS (FY2020)This study presents an analysis of the importance of Arizona State Parks to the state’s economy and to the 13 county economies where state parks are located. The study measures two types of economic effects: county economic impacts and state economic contributions. Both measures are rooted in visitor spending. State parks attract visitors, often from outside the local area, that spend money on such things as lodging, meals, and incidental expenditures. This spending is important to local economies, supporting businesses and jobs, and creating additional rounds of spending in the local economy, known as economic multiplier effects. Spending by non-local visitors, attracted to state parks from outside the local area, represents net new money circulating in the local economy, and therefore is considered as an economic impact. This study presents county-level economic impact estimates for all counties in Arizona with state parks. We also consider all (local and non-local) visitor spending in and around state parks in estimating the economic contribution of state parks to Arizona’s economy. An economic contribution analysis presents a snapshot of existing economic activity surrounding a particular industry or attraction; however, it does not differentiate where spending is coming from. In other words, spending by local residents is simply money being recirculated within the local economy and does not generate net new economic activity within the region’s economy. Finally, we present a brief analysis of the effect of the COVID-19 pandemic on visits to Arizona State Parks to provide context on the level of visits observed during fiscal year 2020.

Arizona County Agricultural Economy ProfilesThis set of county profiles presents a quick reference for important information on agricultural production, agricultural water use, and the role of agriculture in Arizona's county economies. The profiles synthesize data from a variety of sources, first and foremost the recently released 2022 USDA Census of Agriculture, the most comprehensive source of information on county-level agricultural production. County profiles are available in both English and Spanish.

Corn Earworm Management on Desert ProduceCorn earworm (Helicoverpa zea) is a significant pest in desert vegetable production, particularly head lettuce. This guide outlines its biology, host range, and seasonal activity, highlighting the economic damage caused by larvae boring into lettuce heads. Management recommendations emphasize field monitoring, species-specific action thresholds, and the timely application of selective insecticides. Effective control relies on early detection, accurate species identification, and integrating cultural, biological, and chemical strategies to prevent yield loss and contamination.

Insecticide Resistance Management for Beet Armyworm and Diamondback Moth in Desert Produce CropsThis guide provides best practices for insecticide resistance management (IRM) targeting beet armyworm and diamondback moth in desert leafy and Brassica vegetable crops. It offers insecticide efficacy rankings and crop stage recommendations based on local field data, emphasizing the importance of rotating insecticide modes of action (MOA) to prevent resistance. Specific guidance is provided for Diamide use (IRAC Group 28), including soil and foliar application timing, product rotation, and crop proximity considerations. The document supports sustainable IRM by promoting responsible application frequency, product selection, and adherence to University of Arizona action thresholds.

Action Thresholds for Desert Produce CropsThis publication provides an overview of action threshold (AT) guidelines for managing insect pests in leafy vegetables and cole crops in the desert Southwest. Developed from over 30 years of applied field research at the Yuma Agricultural Center, these thresholds help pest control advisors (PCAs) determine when insecticide applications are justified based on pest density or damage levels. The guide distinguishes between prevention strategies, nominal action thresholds, and zero-tolerance thresholds for market contamination, with specific thresholds for pests such as beet armyworm, whiteflies, aphids, thrips, and flea beetles. Emphasis is placed on integrating cultural, physical, and biological control methods before resorting to chemical control, reinforcing the core principles of Integrated Pest Management (IPM).

Assessment of the Contribution of Local and Regional Biomass Burning on PM2.5 in New York/New Jersey Metropolitan AreaThe sources of fine particulate matter (PM2.5, particles with diameter < 2.5 µm) in four monitoring sites in the New York/New Jersey metropolitan statistical area from 2007 to 2017 were apportioned by positive matrix factorization (PMF) of chemical speciation data. Biomass burning, secondary inorganic (i.e., ammonium sulfate and nitrate) and primary traffic exhausts were the predominant PM2.5 sources. The declining trends of PM2.5 mass in all four sites were very well correlated with decreasing secondary sulfate levels due to SO2 emission reductions by coal-fired power plants. The contributions of secondary nitrate, primary traffic exhausts and diesel particles did not change (or slightly increased) over time except for the Queens site, where statistically significant declines were computed. Biomass burning contributions increased in the Queens and Chester sites but declined in the Division Str and Elizabeth Lab sites, although significant interannual variability was observed. Wintertime biomass burning aerosols were most likely due to combustion of contemporary biomass for industrial and domestic heating, and it was linked to the intensity (average minimum temperature) and duration (number of freezing days) of cold weather. The annual summertime biomass burning contributions were correlated with the number of and area burnt by lightning-ignited wildfires. These results indicate that PM2.5 sources in urban environments is changing from anthropogenic secondary sulfate and nitrate to carbonaceous aerosol from local anthropogenic and regional climate-driven biomass burning. This trend may counterbalance emissions controls on anthropogenic activities and modify the biological and toxicological responses and resultant health effects.
