Determinantes tecnológicos de las decisiones de inversión: un análisis de la industria manufacturera mexicana

Technological determinants and investment decisions: a Mexican manufacturing industry analysis

CELINA LOPEZ MATEO SANJUANA MARTHA RIOS MANRIQUEZ RUBEN MOLINA SANCHEZ (2015, [Artículo])

En este trabajo se analiza la influencia de determinantes tecnológicos en las decisiones de inversión de las empresas manufactureras mexicanas. Se utilizan estimaciones de eficiencia obtenidas a partir del Análisis Envolvente de Datos (DEA, por sus siglas en inglés), así como indicadores tecnológicos para las regresiones a través de Mínimos Cuadrados Ordinarios (MCO). El análisis se realiza partiendo de datos de corte transversal. La evidencia empírica sugiere que la eficiencia técnica a partir de los factores productivos capital y trabajo puede incentivar los niveles de inversión.

The influence of technological determinants on the investment decisions of Mexican manufacturing firms is discussed in this work. Efficiency estimates obtained from the Data Envelopment Analysis (DEA) and technology indicators for the regressions through Ordinary Least Squares (OLS) are used to develop the study. The analysis is based on cross-sectional data. Empirical evidence suggests that the technological efficiency that arises from productive factors (capital and labor) may encourage investment.

Contextual realities and poverty traps: Why South Asian smallholder farmers negatively evaluate conservation agriculture

Pragya Timsina Emma Karki Brendan Brown (2023, [Artículo])

Conservation agriculture-based sustainable intensification (CASI) is gaining prominence as an agricultural pathway to poverty reduction and enhancement of sustainable food systems among government and development actors in the Eastern Gangetic Plains (EGP) of South Asia. Despite substantial investment in research and extension programs and a growing understanding of the agronomic, economic and labor-saving benefits of CASI, uptake remains limited. This study explores farmer experiences and perspectives to establish why farmers choose not to implement CASI systems despite a strong body of recent scientific evidence establishing the benefits of them doing so. Through thematic coding of semi-structured interviews, key constraints are identified, which establishes a narrative that current households' resources are insufficient to enable practice change, alongside limited supporting structures for resource supplementation. Such issues create a dependency on subsidies and outside support, a situation that is likely to impact any farming system change given the low-risk profiles of farmers and their limited resource base. This paper hence sets out broad implications for creating change in smallholder farming systems in order to promote the adoption of sustainable agricultural technologies in resource-poor smallholder contexts, especially with regard to breaking the profound poverty cycles that smallholder farmers find themselves in and which are unlikely to be broken by the current set of technologies promoted to them.

Trends in intimate partner, school, and work violence against women in Chihuahua, 2003-2021

Rogelio Rodriguez Nemesio Castillo (2023, [Artículo, Artículo])

This article presents a description and analysis of the trends of violence against women in Chihuahua between 2003 and 2021, employing data from the National Survey of the Dynamics of Household Relationships (Endireh by its acronym in Spanish) for the years 2003, 2006, 2011, 2016 and 2021. The areas chosen for this analysis were intimate partner, school, and workplace. Certain increases and reductions of the problem were observed over time in these areas. Based on the results, recommendations are made for future studies on the topic and public policies to address violence against women.

Necessity as a driver in bending agricultural gender norms in the Eastern Gangetic Plains of South Asia

Pragya Timsina Emma Karki Brendan Brown (2023, [Artículo])

The majority of the farmers in the rural Global South continue to depend directly or indirectly on agriculture for their livelihoods. Despite the fact that women account for almost half of the world's farmers, they face gender-specific challenges such as deeply rooted cultural and social norms that limit their access to land, assets, financial markets, agricultural training, and information. Using semi-structured interviews with farmers in the Eastern Gangetic Plains, this study investigates how necessity is becoming one of the major drivers in the bending of agricultural gender norms. The study investigates the connections between feminist political ecology and agricultural technology production frameworks in order to comprehend the implications of technology adoption and influences on gender norms in communities. Women's participation in agriculture was found to be heavily influenced by social and cultural barriers, and they were frequently subjected to social criticism for breaking the systemic gender norms. This paper emphasizes on the growing pattern of bending gender norms with recommendations for increasing women's participation and scope in future agriculture development initiatives through policies and interventions that emphasize gender equity.

Precise irrigation water and nitrogen management improve water and nitrogen use efficiencies under conservation agriculture in the maize-wheat systems

Mahesh Gathala ML JAT (2023, [Artículo])

A 3-year field experiment was setup to address the threat of underground water depletion and sustainability of agrifood systems. Subsurface drip irrigation (SDI) system combined with nitrogen management under conservation agriculture-based (CA) maize-wheat system (MWS) effects on crop yields, irrigation water productivity (WPi), nitrogen use efficiency (NUE) and profitability. Grain yields of maize, wheat, and MWS in the SDI with 100% recommended N were significantly higher by 15.8%, 5.2% and 11.2%, respectively, than conventional furrow/flood irrigation (CT-FI) system. System irrigation water savings (~ 55%) and the mean WPi were higher in maize, wheat, and MWS under the SDI than CT-FI system. There was saving of 25% of fertilizer N in maize and MWS whereas no saving of N was observed in wheat. Net returns from MWS were significantly higher (USD 265) under SDI with 100% N (with no subsidy) than CT-FI system despite with higher cost of production. The net returns were increased by 47% when considering a subsidy of 80% on laying SDI system. Our results showed a great potential of complementing CA with SDI and N management to maximize productivity, NUE, and WPi, which may be economically beneficial and environmentally sound in MWS in Trans-IGP of South Asia.
