Soil moisture content and maize grain yield under conventional and conservation agriculture practices - results of short term field tests in liselo, Namibia

Christian Thierfelder (2023, [Artículo])

This article focuses on the results from trials developed to monitor the short-term effects of conventionally tilled systems versus CA on soil quality and crop productivity under conditions of the major cropping systems in central, north-central and north-eastern regions of Namibia. Conventional tillage (CT), Minimum tillage (MT), Minimum tillage, mulch (MT-M), Minimum tillage, rotation (MT-R) and Minimum tillage, mulch and rotation (MT-MR) were the primary treatments tested. Significant differences (p≤0.000) among the treatments were observed in the 0-60 cm soil profiles where MT-M plots had the highest soil moisture content (39.8 mm, Standard Error of Mean 0.2815) over the study period. A significant difference (p=0.0206) in grain yield was observed in the second season with CT plots yielding the highest grain yield (3852.3 kg ha-1, standard error of mean 240.35). Results suggest that CA has the potential to increase water conservation and contribute to reduction of the risk of crop failure. Climate change driven degradation under conventional tillage necessitate alternative sustainable tillage methods. Conservation tillage methods and conservation agricultural practices that minimize soil disturbance while maintaining soil cover need to be adopted more locally as viable alternatives to conventional tillage.

Intimate partner violence and its relationship to labor income

Yei Javier Zepeda Hernández Alma Sofia Santillan (2024, [Artículo, Artículo])

In Mexico, 70.1% of women have been victims of violence in their lifetime and the main perpetrator is her intimate partner. Gender violence is a public health problem that has multiple negative impacts in woman and their offsprings. The relation violence and income is an issue that has been scarcely studied for Mexico. The objective of this article is to analyze the intimate partner violence and its relationship to labor income for Mexican women, data used are from the National Survey on the Dynamics of Households Relationships (ENDIREH 2021). The principal component method is used to estimate five kinds of violence; physical, emotional, economic, sexual and, harassment. The instrumental variables method is used to consider the endogeneity of income and violence variables. Except harassment, the results indicate a negative relationship between income and violence. Specifically, sexual violence has the greatest negative effects; women who are victims of sexual violence have an average reduction of 17.4% in monthly labor income. This negative effect represents a loss of just over two month of working days per year and, in the aggregate terms, is equivalent to 0.87% of GDP. The above highlights the importance of orienting public policy actions to work in prevention, attention, punishment and eradications any kind of violence against women.

Urban muralism in cities and towns of Chiapas. Configuring collective experiences and recovering urban spaces

Maria de Lourdes Morales Vargas (2023, [Artículo, Artículo])

This article expresses some reflections on the practice of urban muralism and the result of the approach to urban muralism projects or initiatives that have taken place in some cities, towns and villages in the state of Chiapas. This approach has made it possible to describe the dynamics, forms of participation, processes and agents that participate in the configuration and collective expression of urban murals in these spaces. From descriptive ethnography and its tools it was possible to approach the experiences of urban intervention that coexist with the community, in streets, parks, business walls, houses. This has made it possible to understand the practice of urban muralism as an artistic, collective, community process, a project of regeneration or urban recovery and as a practice of symbolic production of incidence in the space where it is implanted, configuring multiple experiences.

Panorama de la desaparición de personas en Guerrero, 2015-2021.

GABINO SOLANO RAMIREZ (2023, [Artículo])

This work offers a general overview of the disappearance of persons in Guerrero during the period 2015- 2021 seen from the reports published in the local press, and some national media. The objective is to make visible this serious social problem, considered a crime against humanity and of the greatest concern for families and citizens who perceive the feeling of impunity and insecurity. The study follows up on basic indicators of the victims of disappearance, such as the modality (kidnapping, uprising, confrontation, and home invasion), general characteristics of the victims, alleged perpetrators, places and circumstances of the event. Considering the phenomenon as a public issue, the work aims to raise awareness among the population and institutional structures to motivate the generation of strategies to help prevent these disappearances.

Abduction according to Peirce: reflections from the south on the crisis of representation brought on by COVID-19

Paulina Aroch (2023, [Artículo, Artículo])

In this article, I reflect on the importance of abductive thinking for processes of material and conceptual reinvention in the context of the current public health crisis. Inseparable from the climate change engulfing the planet, this crisis provides the basis for a semiotic revolution. Therefore, I interrogate Peirce’s work without losing sight of my own time and place of interlocution. COVID-19 has brought with it a crisis of representation which, in contrast to that unleashed by the Holocaust and World War II, and to which the Frankfurt School responded, demands responses from the Global South. Beginning from Dussel’s call to defend life as a matter of ethical urgency in the face of its irresponsible objectification within colonial capitalist modernity –which arguably triggered the pandemic–, I trace a “nocturnal map” that registers the present meaning-making crisis, and allows for a reimagining and remaking of the world from elsewhere.
