Prácticas de mindfulness y compasión en educación superior. Proyecto multidisciplinar y multicampusla experiencia de la Universidad de Cádiz Sierra Casanova, Carmen Cristina; Castro Yuste, Cristina María; Carnicer Fuentes, Concepción; García Luque, Enrique; Castro Cabrera, María Carmen; Rodríguez Cordón, Carlos; Jardón Serrano, Cristina El creciente reconocimiento del impacto del estrés y la presión académica en la población universitaria ha impulsado la exploración de intervenciones innovadoras para promover el bienestar y optimizar los procesos de enseñanza-aprendizaje. El mindfulness, como práctica de atención plena y consciente del momento presente, ha demostrado ser una herramienta valiosa en diversos contextos, incluyendo el ámbito educativo. El presente capítulo analiza los hallazgos del proyecto “MindfulActúa 2020” de la Universidad de Cádiz (UCA), detallando la fundamentación teórica, la implementación de diversas iniciativas de formación y la evaluación preliminar de su impacto en el profesorado y el alumnado. Se describen las acciones formativas desarrolladas y el protocolo implementado, y se discuten los resultados iniciales en términos de bienestar, clima de aula y potencial mejora del rendimiento académico. Finalmente, se proponen líneas futuras de investigación para profundizar en la optimización de la integración del mindfulness en el contexto de la educación superior.

Preserving cultural heritage stone: Innovative consolidant, superhydrophobic, self-cleaning, and biocidal products Zarzuela Sánchez, Rafael; Luna Aguilera, Manuel Jesús; Martínez Carrascosa, Luis Antonio; Mosquera Díaz, María Jesús Most products commonly employed in the restoration and conservation of cultural heritage stone have not been specifically developed to preserve such elements. In addition, they are plagued by limited performance and structural drawbacks such as low adhesion, poor penetration, and cracking. Another disadvantage is the requirement for most products to be dissolved in volatile organic compounds (VOCs), which produce environmental and human health risks in their use. An innovative sol–gel route for preserving cultural heritage stonework has been developed and is discussed herein. Specifically, a surfactant-assisted sol–gel synthesis produces, in situ on the stonework, crack-free nanomaterials to be used as long-term consolidants. Additionally, hydrophobic, water-repellent, self-cleaning, and biocidal properties can be incorporated into the product by innovative chemical modifications of the proposed synthesis route.

Occurrence, sources and environmental risk assessment of organic micropollutants in coastal sediments from the Atacama Region (Chile) Tovar Salvador, María de la Luz; Pintado Herrera, Marina Guadalupe; Lara Martín, Pablo Antonio; Bonnail, Estefanía Nowadays, there is still a scientific knowledge gap regarding occurrence and distribution of organic contaminants in remote areas. In this study, we have monitored for the first time the presence of a wide range of persistent and emerging organic pollutants in the Atacama Desert coastal region (Chile), a key area in the Humboldt Current System. Nonylphenols (NPs), polycyclic aromatic hydrocarbons (PAHs), pesticides, UV filters, synthetic fragrances, and organophosphate flame retardants (OPFRs) were determined in sediments along the >500 km length Atacama coastline. NPs, well-known endocrine disruptors, were the predominant pollutants in the area (up to 333.5 ng g−1 dw). We identified inputs of different classes of contaminants from anthropogenic activities such as mining, agriculture, direct effluent discharges, harbors, energy plants, recreational activities, and tourism occurring along the coastline. Environmental risk assessment through calculation of hazard quotients (HQs) showed a high ecological risk level for NPs in the three provinces of Atacama (HQ >1). In the case of PAHs, (pyrene, benz(a)anthracene, chrysene, acenaphthene, naphthalene and benzo(a)pyrene) HQ >1 was showed in Copiapó province. Furthermore, estradiol equivalent concentrations (EEQ) were determined to estimate estrogenicity of the environmental sediment samples. The maximum EEQ value was for NPs in H1 (Carrizal Bajo wetland), province of Huasco, where the highest concentration of NPs was found. The sampling point H1 is a particular location because it is the exit of a wetland and a tourist point used as a beach. The potential risks of anthropogenic chemical substances impacting remote regions such as the one studied here highlight the need of expand monitoring efforts worldwide for a better assessment of the global pollution status.

Sunscreens in Coastal Ecosystems. Chapter:Fate and behavior of uv filters in the marine environment Pintado Herrera, Marina Guadalupe; Lara Martín, Pablo Antonio UV filters are released into the coastal areas by a combination of different sources, including wastewater discharges and direct input related to recreational activities. To fully understand the risks associated with the occurrence of UV filters in the marine environment, better knowledge on their distribution and environmental behavior is required. So far, concentrations of several parts per trillion have been reported in different marine settings from touristic areas. Temporal variations in levels for organic UV filters have been associated with beach use, whereas for inorganic UV filters a preferential accumulation in the surface microlayer was observed. The latter are often released as nanoparticles, which have a tendency to form aggregates and precipitate. Due to their relatively high hydrophobicity, organic UV filters can also end up in the seafloor. Although sediments are not so frequently monitored at seawater, higher UV-filter levels (a few ng g−1) are usually found. Regarding their reactivity in the marine environment, the elucidation of degradation pathways and kinetics is still mostly unknown, although photochemical degradation seems to be a major transformation route for most organic UV filters. Regarding inorganic UV filters, their nanoparticles are subjected to weathering or aging and have also tendency to generate free radicals such as hydrogen peroxide under solar irradiation
