¡Que se llega y que se llega! Análisis de la ritualidad en el sistema de peregrinaciones de la Caravana Nacional de la Fe, S.L.P.

LUZ DEL CARMEN ACEVEDO RODRIGUEZ (2020, [Tesis de maestría])

"Esta tesis se compone de cuatro capítulos formados tomando en cuenta la especificidad de la investigación y los intereses particulares propios de la zona de estudio: En el primer capítulo encontramos un acercamiento al peregrinaje donde se describe, a grandes rasgos, el proceso de conceptualización de este fenómeno y los principales autores que contribuyeron en la construcción del bagaje teórico, así como nuevas posturas surgidas de los cambios debidos a la globalización y las maneras de resistencia de la religiosidad popular en relación a ello. El segundo capítulo contiene datos etnográficos que describen todo lo relacionado con la práctica peregrina del grupo Caravana Nacional de la Fe, S.L.P., desde la organización social de la celaduría en términos estructurales, hasta las peregrinaciones que realizan a lo largo del año. El tercer capítulo describe los objetos en relación con la ritualidad y la impregnación de ésta y finalmente, el cuarto capítulo aborda el cuerpo desde una perspectiva sociocultural, alejado de la simple función biológica y fisiológica, sino entendido como una construcción social a partir de las prácticas que con éste se hacen y los elementos culturales del grupo de pertenencia".

Optimization of the alkali-silane treatment of agave lechuguilla fibers (ixtle) for potential reinforcement in polymeric composites

NOEMI JARDON MAXIMINO MARIAMNE DEHONOR GOMEZ Rolando Villa Moreno MARIA DOLORES BAEZA ALVARADO Luis Edmundo Lugo Uribe (2023, [Artículo])

Reinforced polymeric composites with natural fibers have garnered significant interest in recent years due to the need for biomass utilization and the requirements of various industries, such as automotive and construction. Among these natural fibers, Agave lechuguilla fiber, commonly known as ixtle (FIx) or Tampico fiber, exhibits important characteristics such as length, high strength, and durability. However, there is limited literature on its conditioning, functionalization, and utilization as a reinforcing material in polymeric composites (CP). This study presents the optimization of the alkali-silane treatment of FIx, identifying the most suitable reaction conditions to enhance their thermal stability, tensile strength, and silane coupling agent (ACSi) grafting on the fiber surface. The chemical treatment with ACSi proved highly effective, resulting in a significant grafting content, which was confirmed through FTIR and SEM–EDS analyses. The high level of functionalization did not compromise the mechanical performance of the fibers, suggesting that functionalized FIx holds great potential as a reinforcing material in CP. These findings open new paths for the sustainable use of Agave lechuguilla fibers, contributing to the development of environmentally friendly and high-performance polymeric composites in various industrial applications.

Variabilidad estacional de la productividad primaria y su relación con la estratificación vertical en la bahía de La Paz, BCS

Seasonal variability of primary productivity and its relation to the vertical stratification in La Paz, BCS

RAFAEL CERVANTES DUARTE RUBEN ANTELMO MORALES PEREZ JOSE EDUARDO VALDEZ HOLGUIN (2003, [Artículo])

Se estimó la productividad primaria (pp) vía fluorescencia natural en la bahía de La Paz durante octubre de 1996, marzo, abril, mayo, junio, julio, septiembre, noviembre de 1997, y enero de 1998. simultáneamente a los registros de pp se realizaron perfiles verticales de temperatura (CTD) para determinar la estructura de la columna de agua, y de los cuales se estimó el índice de estratificación (_) de 0 a 100 m de profundidad. Durante primavera se observaron los valores promedio más altos de pp (16 mg C m-3 h-1) y valores bajos de _ (50 J m-3) que corresponden a una columna de agua casi homogénea. En contraste, en las subsecuentes estaciones (verano y otoño), la pp decreció a valores mínimos (2 y 5 mg C m-3 h-1), mientras que _ se incrementó significativamente (249 y 347 J m-3). Los resultados indican que existe una dependencia lineal de la pp y la mezcla en la columna de agua (r2 = 0.62, p<0.05) durante los meses de verano. Periodos con una alta estratificación tienden posiblemente a inhibir la fertilización de la capa superficial, mientras que una columna de agua bien mezclada facilita el proceso de fertilización. Por lo tanto, es evidente que en la Bahía de La Paz la estratificación asume un papel importante como mecanismo que controla la pp y explica parcialmente la variabilidad estacional observada en la bahía.

Women, economic resilience, gender norms in a time of climate change: what do we know?

Cathy Farnworth Anne Rietveld Rachel Voss Angela Meentzen (2023, [Artículo])

This literature delves into 82 research articles, published between 2016 and 2022, to develop a deep understanding of how women manage their lives and livelihoods within their agrifood systems when these systems are being affected, sometimes devastatingly, by climate change. The Findings show that four core gender norms affect the ability of women to achieve economic resilience in the face of climate change operate in agrifood production systems. Each of these gender norms speaks to male privilege: (i) Men are primary decision-makers, (ii) Men are breadwinners, (iii) Men control assets, and (iv) Men are food system actors. These gender norms are widely held and challenge women’s abilities to become economically resilient. These norms are made more powerful still because they fuse with each other and act on multiple levels, and they serve to support other norms which limit women’s scope to act. It is particularly noteworthy that many institutional actors, ranging from community decision-makers to development partners, tend to reinforce rather than challenge gender norms because they do not critically review their own assumptions.

However, the four gender norms cited are not hegemonic. First, there is limited and intriguing evidence that intersectional identities can influence women’s resilience in significant ways. Second, gender norms governing women’s roles and power in agrifood systems are changing in response to climate change and other forces, with implications for how women respond to future climate shocks. Third, paying attention to local realities is important – behaviours do not necessarily substantiate local norms. Fourth, women experience strong support from other women in savings groups, religious organisations, reciprocal labour, and others. Fifth, critical moments, such as climate disasters, offer potentially pivotal moments of change which could permit women unusually high levels of agency to overcome restrictive gender norms without being negatively sanctioned. The article concludes with recommendations for further research.

¿Por qué invertir en la conservación de la biodiversidad y servicios ecosistémicos?

JUAN ANTONIO BARRON SEVILLA GLORIA CASTAÑEDA GUTIERREZ ANA MARIA HERRERA CRUZ (2022, [Artículo])

La biodiversidad y los servicios ecosistémicos son vitales para la humanidad. Sin embargo, en una economía de mercado su importancia no se refleja en el gasto público e inversión en su conservación. Aun dentro de este contexto, existen elementos que permiten apreciar su importancia para el sustento de las actividades productivas sostenibles, cumplimiento de políticas públicas y bienestar para la sociedad.
