The project to create the State of the Center, 1870

EVELIN MARES CENTENO (2022, [Artículo])

El 21 de julio de 1870 los principales vecinos de la ciudad de León y el cabildo emprendieron las gestiones necesarias para crear una nueva entidad federativa que llevaría el nombre de Estado del Centro, la cual estaría compuesta por ayuntamientos de los estados de Jalisco y Guanajuato. A pe sar de que se trató de un proyecto político que se llevó a cabo en un momento en el que se estaba reconfigurando la geografía política del país, y de que contaba con los requisitos que solicitaba la Constitución de 1857, no logró consolidarse. Sin embargo, su estudio permite acercarse a conocer el proceso de configuración política del territorio.

On July 21, 1870, the main residents of the city of León and the council, undertook the necessary steps to create a new federal entity that would bear the name of the State of the Center, which would be composed of municipalities of the states of Jalisco and Guanajuato. Despite the fact that it was a political project that was carried out at a time when the

political geography of the country was being reconfigured, and that it had the requirements requested by the 1857 Constitution, it failed to consolidate. However, its study allows us to get closer to knowing the process of political configuration of the territory.

Catching-up with genetic progress: Simulation of potential production for modern wheat cultivars in the Netherlands

João Vasco Silva Frits K. Van Evert Pytrik Reidsma (2023, [Artículo])

Context: Wheat crop growth models from all over the world have been calibrated on the Groot and Verberne (1991) data set, collected between 1982 and 1984 in the Netherlands, in at least 28 published studies to date including various recent ones. However, the recent use of this data set for calibration of potential yield is questionable as actual Dutch winter wheat yields increased by 3.1 Mg ha-1 over the period 1984 – 2015. A new comprehensive set of winter wheat experiments, suitable for crop model calibration, was conducted in Wageningen during the growing seasons of 2013–2014 and of 2014–2015. Objective: The present study aimed to quantify the change of winter wheat variety traits between 1984 and 2015 and to examine which of the identified traits explained the increase in wheat yield most. Methods: PCSE-LINTUL3 was calibrated on the Groot and Verberne data (1991) set. Next, it was evaluated on the 2013–2015 data set. The model was further recalibrated on the 2013–2015 data set. Parameter values of both calibrations were compared. Sensitivity analysis was used to assess to what extent climate change, elevated CO2, changes in sowing dates, and changes in cultivar traits could explain yield increases. Results: The estimated reference light use efficiency and the temperature sum from anthesis to maturity were higher in 2013–2015 than in 1982–1984. PCSE-LINTUL3, calibrated on the 1982–1984 data set, underestimated the yield potential of 2013–2015. Sensitivity analyses showed that about half of the simulated winter wheat yield increase between 1984 and 2015 in the Netherlands was explained by elevated CO2 and climate change. The remaining part was explained by the increased temperature sum from anthesis to maturity and, to a smaller extent, by changes in the reference light use efficiency. Changes in sowing dates, biomass partitioning fractions, thermal requirements for anthesis, and biomass reallocation did not explain the yield increase. Conclusion: Recalibration of PCSE-LINTUL3 was necessary to reproduce the high wheat yields currently obtained in the Netherlands. About half of the reported winter wheat yield increase was attributed to climate change and elevated CO2. The remaining part of the increase was attributed to changes in the temperature sum from anthesis to maturity and, to a lesser extent, the reference light use efficiency. Significance: This study systematically addressed to what extent changes in various cultivar traits, climate change, and elevated CO2 can explain the winter wheat yield increase observed in the Netherlands between 1984 and 2015.

Mucho más que hilos, aceites y semillas: reconociendo el valor de los linos silvestres

Juan González-Velasco MIREYA BURGOS HERNANDEZ Alejandra Villalvazo Hernández (2023, [Artículo])

Seguramente alguna vez un amigo o vecino te ha recomendado consumir semillas de linaza para mejorar tu digestión, y no sería raro que también cuentes con alguna prenda elaborada con lino. Pues bien, ambos productos provienen de una sola especie, Linum usitatissimum que es de origen europeo e introducida en México, donde actualmente se cultiva. Sin embargo, existen cerca de 180 especies de Linum en el mundo y 24 en nuestro país, las cuales, son subutilizadas o se desconoce su uso. El conocimiento de este grupo puede representar nuevas alternativas de aprovechamiento para las familias campesinas.

LGBT+ media on the Internet: experiences of communication and information in Mexico

RAUL ANTHONY OLMEDO NERI (2023, [Artículo, Artículo])

Two digital LGBT+ media in Mexico are analyzed to understand the implications of their operation and their articulation with the informational and social needs of sex-gender populations. It starts from the communicational perspective to conceptualize these projects as exercises in technological appropriation but highlighting their empirical intersections with other analytical frameworks. Through the method of systematizing the experience, the trajectories of ANODIS and Seis Franjas Mx have been recovered; through semi-structured interviews conducted with their co-founders in February 2022, the reasons, horizons and challenges that these projects have faced are analyzed. The results show that the lack of LGBT+ content and representations in the media motivate the creation of these projects, which articulate a sense of collaboration and sociality with other users belonging to sex-gender communities. In addition, the people participating in these projects are part of the LGBT+ populations, becoming them producers and consumers of information that claim the gender-identity dimension in the content. Likewise, these initiatives are specified in the youth stage of their co-founders, which refers to rethinking the role of LGBT+ youth in the new forms of activism and socialization mediated by Internet. Finally, given the progressive formation of this area of ​​knowledge and the lack of consensus on its definition, it is proposed to name this interdisciplinary field of study as LGBT+ Communicational Studies, to show an epistemological perspective from communication and a Latin American ontological position.

Addressing agricultural labour issues is key to biodiversity-smart farming

Thomas Daum Frédéric Baudron Matin Qaim Ingo Grass (2023, [Artículo])

There is an urgent need for agricultural development strategies that reconcile agricultural production and biodiversity conservation. This is especially true in the Global South where population growth is rapid and much of the world's remaining biodiversity is located. Combining conceptual thoughts with empirical insights from case studies in Indonesia and Ethiopia, we argue that such strategies will have to pay more attention to agricultural labour dynamics. Farmers have a strong motivation to reduce the heavy toil associated with farming by adopting technologies that save labour but can negatively affect biodiversity. Labour constraints can also prevent farmers from adopting technologies that improve biodiversity but increase labour intensity. Without explicitly accounting for labour issues, conservation efforts can hardly be successful. We hence highlight the need for biodiversity-smart agriculture, that is farming practices or systems that reconcile biodiversity with land and labour productivity. Our empirical insights suggest that technological and institutional options to reconcile farmers' socio-economic goals and biodiversity conservation exist but that more needs to be done to implement such options at scale.

A pre-pandemic study about recreational uses in the Mexico Park located at Mexico City (year 2017)

Ramiro Flores-Xolocotzi Sergio Ceballos (2022, [Artículo, Artículo])

A recreational study was carried out through surveys in the Parque México in Mexico City. For this, the relationship between visit patterns with socioeconomic information, uses and perceptions of visitors with 18 years old or older was analyzed. This research uses descriptive statistics and a non-linear canonical correlation analysis to analyze relationships between variables. An ordered probit regression was also performed to determine the variables that explain the frequency of recreational use. It was obtained that the Park mainly receives visitors with at least bachelor's degree (78.6%) and high incomes (more than 50% have a monthly family income higher than $10,000.00 pesos and 27.6% receive more than $30,000.00 per month). Considering the results, the conclusions are that although the highest percentage of the studied population comes from neighborhoods outside the Roma-Condesa Corridor: then the visitors who live in the Corridor and who have higher incomes, have weight in the description of the model. The results allow to conclude too, that higher income increases the frequency of use. It is also observed that the park is used during the Monday to Friday by more than 50% of the population of visitors and with a high percentage of use in the mornings.
