Examining Perceptions of Spanish Language Health Information Among Hispanics Living in the United States: A Qualitative Study Assessing Videos, Brochures, and Websites

Background Nationally, Hispanics experience health disparities manifested as a higher prevalence of chronic diseases in comparison to non-Hispanic Whites. Factors that influence health disparities in this population include inadequate dissemination of culturally and linguistically appropriate health information. Method Our qualitative analysis is based on data obtained from three focus groups with Spanish-speaking Hispanic adults conducted at a clinic in Nebraska. Participants were asked about their perceptions of health information in the form of videos, brochures, and websites. We followed the consolidated criteria for reporting qualitative research and used the theoretical framework of content analysis. Results For videos, attributes associated with higher levels of trust included a friendly health professional, the logo or name of a health care institute, and a reference specifying “se habla Español.” For brochures, attributes associated with trust included use of visual aids, use of numerous colors and big font sizes, the year of printing, and a health care agency logo. For websites, characteristics associated with trust were inclusion of plain language, use of pictures and videos, and date of last update. In all focus groups, participants perceived the use of mixed English/Spanish language in health information from pamphlets and websites as unprofessional. The use of unknown governmental logos in health promotional videos and websites was perceived as untrustworthy information. Conclusions Spanish-speaking Hispanics prefer health information supported by a health care agency or delivered by a health care professional. Health communication strategies should avoid the use of mixed English/Spanish language in sensitive information especially when combined with governmental logos.

Planificacion de un Sector Energetico Resiliente: Como Asegurar Electricidad Confiable, Segura y Asequible (Spanish Translation)

This is the Spanish translation of 'Planning a Resilient Power Sector: Ensuring Reliable, Secure, Safe, and Affordable Electricity' (NREL/TP-7A40-71543). Decision makers around the globe are exploring strategies to ensure the reliable, secure, safe, and affordable supply of electricity to power economic growth and achieve development goals. Vulnerabilities of the power sector to natural hazards (e.g., acts of nature, severe weather, and climate variabilities), technological hazards (e.g., accidents and system or structure failures), and threats or human-caused incidents (e.g., intentional cyber-attacks or acts of terror) can impede the provision of the energy services necessary to achieve these goals. Although decision makers cannot prevent an act of nature such as an earthquake, they can anticipate, prepare for, and adapt to potential vulnerabilities through planning. The purpose of power sector resilience planning is to identify vulnerabilities and devise strategies to mitigate them. This document reviews some of the hazards that power sectors face and how decision makers can plan to increase resilience.

Fortalecimiento de la Electrificación Rural en Honduras: Una Evaluación Integrada de PV+BESS y Usos Productivos de la Electricidad en Gracias a Dios, Honduras [Empowering Rural Electrification in Honduras: An Integrated Assessment of PV/BESS and Productive Uses of Electricity in Gracias a Dios] (Spanish Translation)

Honduras faces significant challenges in its energy sector, particularly in rural areas where access to reliable and affordable electricity remains limited. The flagship rural electrification initiative for Honduras Secretary of Energy (SEN) is the Politica de Acceso Universal a la Electricidad (PAUEH - Universal Electricity Access Policy), a key solution for addressing this energy poverty is the deployment of more than 1700 distributed solar and hybrid mini-grid solutions. In late 2023 as a first step towards supporting SEN's electrification efforts, the National Renewable Energy Laboratory (NREL) developed a literature review of SEN electrification policy documents and conducted a series of technical capacity-building workshops with SEN and other energy sector stakeholders in Honduras focused on using NREL's open-source REopt tool to conduct techno-economic assessments and develop least-cost optimizations for potential solar + storage mini-grid systems. Building on some initial capacity building on mini-grid modeling, the National Renewable Energy Laboratory (NREL) worked with SEN to develop a detailed techno-economic assessment for electrifying two schools, a healthcare clinic, and a hospital in a hypothetical community within the department of Gracias a Dios. The analysis also evaluates the business case for cold storage productive use of energy (PUE) applications for the fisheries value chain and how the incorporation of these PUE loads potentially impacts both the viability of the PV+BESS solutions as well as local economic development. By assessing the potential for deployment of integrated PV/BESS systems to both support critical community services like education and healthcare, as well as potential for downstream enterprise and economic development, this analysis represents a first step that can help to inform specific strategies for development of pilot PV+BESS projects aligned with national priorities and sector level planning under PAUEH.

Probabilidad de que los murcielagos sufran barotraumatismo cerca de palas de aerogeneradores en movimiento (Spanish)

In October 2018, the International Energy Agency Wind Task 34 - Working Together to Resolve the Environmental Effects of Wind Energy (WREN) - organized a virtual forum to discuss the likelihood of bats experiencing barotrauma when flying near moving wind turbine blades. The forum included experts in bat biology and physiology, bat and wind turbine interactions, wind turbine technology, and atmospheric sciences. This educational brief summarizes the discussion during the forum and written comments from those who could not attend. Relevant literature was used to provide additional context when needed. Possible explanations regarding the direct cause of bat mortality at operating wind turbines are (1) blunt force trauma caused by turbine blades striking individual bats, often referred to as collisions, and (2) barotrauma, resulting from exposure to pressure changes located near the surface of moving wind turbine blades. While collision- related mortality is easily understood, the mechanism causing barotrauma is more complex. Fast-moving wind turbine blades create regions of high- and low-pressure variations along the blade surfaces. If bats fly within these regions, the rapid change in pressure may cause internal bleeding, damage to lungs or other organs, and damage to the inner ear. However, sufficient data demonstrating barotrauma as a common cause of bat mortality at wind turbines are lacking. Moreover, the pressure variation necessary to cause barotrauma in bats is so close to the surface of turbine blades that there is a higher probability of direct contact with the blades than of solely experiencing barotrauma. Regardless of the cause, bats are interacting with fast-moving wind turbine blades, and these interactions are resulting in fatalities. Resolving this issue will require a better understanding of bat behavior and cost-effective measures to reduce interactions between bats and wind turbines.

Modelos de riesgo de colision: una herramienta para evaluar los riesgos para las aves rapaces en instalaciones de energia eolica (Spanish)

In January 2022, the International Energy Agency Wind Task 34 - Working Together to Resolve the Environmental Effects of Wind Energy (WREN) - organized a forum to discuss aspects of raptor collision risk with wind turbines. The forum included experts in raptor biology and physiology, collision risk modeling, wind energy development, and atmospheric scientists from seven countries. They represented a range of international stakeholder groups including academia, government agencies, national laboratories, and wildlife consultants. This educational brief summarizes the discussion during the forum and written comments from those who could not attend. Relevant literature was used to provide additional context when needed. For several species of raptors, such as golden eagles (Aquila chrysaetos), griffon vultures (Gyps fulvus) and white-tailed eagles (Haliaatus albicilla), collision risk with wind turbines continues to be a concern among stakeholders. These concerns include the potential population-level impact related to collisions, compliance with regulatory mechanisms for protected species, and the ability to generate renewable energy. To make siting and operational decisions, stakeholders require some level of certainty of the risk associated with a proposed project. Understanding this risk, in part, requires species-specific data on raptors and how they perceive and interact with wind farms or individual wind turbines. Collision risk models (CRMs) are a tool, often used in environmental impact assessments, that can provide estimates of risk relative to specific turbines or an entire wind farm. However, questions associated with the uncertainty in CRM estimates remain. This is the Spanish translation of NREL/FS-5000-84747, "Collision Risk Modeling - A Tool for Assessing Risks to Raptors at Wind Energy Facilities."

La Jerarquia de Mitigacion (Spanish)

The mitigation hierarchy is a widely used framework to inform conservation decisions. The hierarchy offers a structured set of steps for how projects can lessen negative impacts or lead to an increase in biodiversity. In its simplest form, the mitigation hierarchy includes three stages: (1) avoid creating impacts from the outset, (2) minimize the impacts that cannot be avoided, and (3) compensate for or offset the impacts that cannot be minimized. Proper application of the hierarchy should decrease impacts of the project over time, such that most of the impact is alleviated through avoidance, leaving a modest amount remaining to minimize, and only a residual to compensate. In practice, avoidance should be prioritized and can be a cost-effective means of mitigation. Whereas compensation should be considered the lowest priority and should only be applied in situations in which the previous mitigation steps were unable to fully alleviate undesirable impacts. This is the Spanish translation of NREL/FS-5000-85363, "The Mitigation Hierarchy."

Safety Assessment of El Cabril, the Spanish Surface Disposal facility for LILW and VLLW - 17233

El Cabril project was launched in 1986, for Low and Intermediate Level Waste (LILW) disposal, based on concrete barriers and concrete disposal units. The operation of a Very Low Leve Waste (VLLW) complementary facility based on clay and High Density Polyethylene (HDPE) barriers and different types of disposal units started in 2008. Two main objectives are considered in the design: Immediate and post-closure protection and no radiological restrictions, after institutional control period. To fulfil these objectives several design criteria like waste isolation through a multi-barrier system, surveillance period no longer than 300 years and limitation of activity are applied. The Safety Assessment process follows a methodology which, taking into account important facts like safety and design criteria, time frame, radiological protection criteria, waste characteristics, environment, FEPs (features, events and processes), etc., develops different scenarios, models and calculations to define the safety approach. This safety approach follows the current guides and recommendations of international organizations, it covers the potential impact of the facility for the operational and long-term periods and it includes normal evolution and less likely accidental and inadvertent human intrusion events. All the studies and considerations done for the Safety Assessment have to be included in a safety Report, required for getting the Operation License for Nuclear Installations in Spain. The content of this Report is defined by the Spanish regulation and it has to be revised if there is a change in the facility that may affect the safety. It is also mandatory making a Safety Periodic Review (every 10 years in the case of El Cabril) that has to be presented to the Regulatory Council. This paper outlines the principles, objectives and criteria of El Cabril's disposal installation and it explains the safety assessment performed, for both LILW and VLLW disposal, as part of the documentation produced to obtain the authorization to operate.

Playa de Ponce's Advancements in Energy Affordability and Reliability (Spanish Translation)

Un Nuevo Amanecer Inc. (UNA), a community-based nonprofit organization, partnered with the U.S. Department of Energy's Energy Technology Innovation Partnership Project (ETIPP) to develop a Strategic Energy Plan (SEP) for the community of Playa de Ponce on the southern coast of Puerto Rico. The SEP provides a community-driven roadmap to improve local energy systems by identifying shared priorities, strategies, and actions that support a more reliable, affordable, and resilient energy future. Over a seven-month period, researchers from the National Laboratory of the Rockies (NLR) worked with UNA, the Puerto Rico Hispanic Federation, community leaders, and residents to gather input through engagement workshops held in March and June 2025. These discussions helped define the community's energy vision and identify key challenges, including high electricity costs, unreliable service during extreme weather events, and risks to public health and safety - particularly for the community's aging population. This fact sheet summarizes the key elements of the Strategic Energy Plan, including four priority strategies organized around three focus areas identified by the community: energy reliability, safety and security, and stakeholder participation, education, and capacity building. Together, these strategies outline actionable pathways to strengthen Playa de Ponce's energy resilience and support long-term community goals. The plan serves as a shared reference for community members, local organizations, and government partners working to advance energy solutions in Playa de Ponce and complements broader municipal and island-wide planning efforts.

Seven good practices for the environmental licensing of coastal interventions: Lessons from the Italian, Cuban, Spanish and Colombian regulatory frameworks and insights on coastal processes

Highlights: • Environmental licensing procedures (ELP) line up by projects instead of environments. • The ELP of four countries was compared according to the generic EIA stages. • The study relies upon the revision of EIA legislation and technical guidelines. • Seven EIA good practices were extracted from the ELP analysis of the four countries. • A changing approach is proposed for the EPL performance on coastal interventions. - Abstract: Environmental licensing is the regulatory procedure that enforces the environmental impact assessment (EIA) of human activities inside a given country. Despite worldwide acceptance of EIA as a valid tool, its application in coastal environments is still too diverse and limited regarding the specificity of the natural processes influencing the shore. This paper compares the Environmental Licensing Procedure (ELP) of four countries, focusing on the activities that could affect the coastal geomorphology. The acquisition and validation of information were done through interviews with EIA representatives in each country, who signalized the official documents of environmental licensing and coastal management to be considered in the documentary review. The results present those differences and similarities among ELP stages in each country, based on the principles of the International Association of Impact Assessment and the national documents analyzed. In sum, 59 interventions associated with human uses and activities in the coastal zone were compared according to the prescriptive character of the environmental licensing in Italy, Spain, Cuba and Colombia. The natural processes influencing coastal geomorphology were also analyzed within the technical criteria included in the official guidelines for the EIA, finding a generalized weakness in processes associated with geochemical courses on coastal environments. By way of discussion, seven good practices are illustrated, according to their pertinence to the impact assessment of the coastal zone: 1) The integration of screening and scoping; 2) Evaluation focusing on the environment rather than the intervention; 3) Binding the coastal zone delimitation; 4) Institutional articulation; 5) Accreditation of environmental consultancies; 6) Official guidelines by types of environment; 7) The integration of environmental geographic information. Finally, general conclusions to assist EIA practitioners operating in the four countries and recommendations to lead further research are provided, introducing a novel process-oriented approach for ELP.

Maternal selenium status and neuropsychological development in Spanish preschool children

Highlights: • The association between maternal Se and neurodevelopment at 5 years of age has been evaluated. • An inverted U-shaped relationship was observed: low and high Se seem to be harmful for neurodevelopment. • Breastfeeding seems to offset the low Se levels during the prenatal period. • Prenatal period could be especially vulnerable to Se neurotoxicity. The relationship between maternal selenium (Se) status and child neurodevelopment has been scarcely assessed. In a previous study we observed an inverse U-shaped association between maternal Se concentrations and infant neurodevelopment at 12 months of age. In this study, this non-linear association was explored at preschool age. The effect modification by breastfeeding, child's sex and cord blood mercury was also evaluated.
