How Patterns of Democracy Impact Policy Processes: When Lijphart and Sabatier Meet

European Policy Analysis, Volume 11, Issue 2, Page 254-270, Spring 2025.
ABSTRACT Policy process theories and institutional theories are two foundational strands in political science, both concerned with how people engage in politics. However, they differ in their focus, with policy process theories emphasizing the roles of actors, while institutional theories concentrate on the structures in which these actors are embedded.

Full‐spectrum cannabidiol reduces UVB damage through the inhibition of TGF‐β1 and the NLRP3 inflammasome

Photochemistry and Photobiology, Volume 101, Issue 1, Page 83-105, January/February 2025.
Photoprotective and antiinflammatory benefits of full‐spectrum cannabidiol (FS‐CBD) against UVB‐induced cellular death were examined in this study. FS‐CBD protected against UVB‐induced bacterial death for 30 min. FS‐CBD protected against UVB‐induced cells, in an in vitro keratinocyte cell model.

Genetic Assignment Tests to Identify the Probable Geographic Origin of a Captive Specimen of Military Macaw (Ara militaris) in Mexico: Implications for Conservation

Diversity, 2021
The Military Macaw (Ara militaris) faces a number of serious conservation threats. The use of genetic markers and assignment tests may help to identify the geographic origin of captive individuals and improve conservation and management programs.

La sombra alargada del patrón: Gamonalismo y hábitos hacendatarios en Chimborazo tras la reforma agraria

The Journal of Latin American and Caribbean Anthropology, Volume 29, Issue 4, Page 352-363, December 2024.
Abstract This paper explores selective aspects of the historical processes of organization of the kichwa peasantry in the Andes of Ecuador. Based on the analysis of two representative cases of confrontation between peasants and landowners over access to land in the province of Chimborazo, it discusses the relevance of the concept of “gamonalismo” as ...

Evolution history and the importance of genomic diversity facing climate change. The case of Agave marmorata Roezl., a microendemic agave used for mezcal production

PLANTS, PEOPLE, PLANET, Volume 6, Issue 6, Page 1381-1397, November 2024.
For hundreds of years, Agave marmorata plants have been used in the production of alcoholic beverages in Mexico. This species is very important in small‐scale rural economies because it is a large plant, yielding five liters of mezcal. However, the production of these beverages takes place when it reaches its reproductive stage, which takes up to 35 ...

Histologic, metabolomic, and transcriptomic differences in fir trees from a peri‐urban forest under chronic ozone exposure

Ecology and Evolution, Volume 14, Issue 5, May 2024.
Urbanization alters ecosystems and evolutionary processes. Processes like air pollution by tropospheric ozone contribute to the decline of urban and peri‐urban ecosystems, such as Abies religiosa forests in the peripheral mountains southwest of Mexico City.

Seed‐predation and dispersal by ants determine plant‐species dominance and diversity in a semi‐arid grassland

Journal of Vegetation Science, Volume 35, Issue 3, May/June 2024.
Granivorous ants affect plants negatively through predation and positively by dispersal. Compared with ant exclosures, plots with ants had lower richness and increased dominant species diversity. When exposed to ants, the species that increased in density were those whose aggregation increased, suggesting that positive effects of ants are not related ...

Desnacionalización, Regímenes Visuales y Resistencia: Gitanos Americanos en Ciudad de México

Cultural Anthropology, Volume 39, Issue 2, Page 171-193, May 2024.
RESUMEN La idea de que el carácter de los roma es exterior al flujo de la dinámica de los procesos históricos es un organicismo alienante en México y América Latina, pues los regímenes visuales han reproducido estereotipos culturales y raciales excluyentes sobre ellos.
