Implementación de algoritmos basados en la teoría de grafos en proyectos de sectorización de redes de agua potable

Velitchko Tzatchkov VICTOR HUGO ALCOCER YAMANAKA (2011, [Artículo])

Los proyectos de sectorización de redes de agua potable, en proceso en diferentes ciudades mexicanas actualmente, consisten en dividir la red de la ciudad en varias subredes o sectores más pequeños con una o máximo dos entradas de agua por sector. Para diseñar los sectores se emplean modelos de redes de agua potable que revisan si la sectorización propuesta puede funcionar hidráulicamente de manera adecuada. Para los proyectos de sectorización en redes grandes se requieren, sin embargo, facilidades algorítmicas adicionales, como análisis de conectividad, zona de influencia y contribución de cada fuente sobre el consumo. En el presente artículo se discuten eficientes algoritmos de este tipo basados en la teoría de los grafos, implementados en un sistema de cómputo.

Tutoring to novel teachers. A fragment of skylight from the border of Ciudad Juarez

Silvia Gabriela Alvídrez Minora (2022, [Artículo, Artículo])

This article describes and interprets the tutoring of novice teachers in a preschool area of ​​Ciudad Juarez. The study is situated in the interpretive paradigm; It makes use of the ethnographic method and research techniques such as participant observation and interview. The partial results show that tutoring is considered an important process for the insertion and professionalization of new teachers; however, it is mentioned that this enriching relationship is only possible when there is communication between all the people involved in the tutoring, in addition to being open to peer learning.

Systematic Literature Review on Smart Specialization: Future Prospects and Opportunities

Beatriz Rosas Michael Demmler (2023, [Artículo])

"Smart specialisation (SS) has been the new cohesion policy in the European Union during the last two periods. The present study aims to analyse the most relevant existing state-of-the-art literature on smart specialisation through a systematic and bibliometric review. Using the Web of Science bibliographic database, we analysed the content of 207 articles under the TCCM methodology and constructed a network of citations in order to summarize theories, characteristics, context and methods presented in existing studies on the topic. Our results show the theoretical and methodological gaps of the past, such as Entrepreneurial Discovery Process and SS indicators. These remain to the present day. The context analysis showed that the scope of smart specialisation extended beyond the frontiers of the European Union, given how it has been adopted by other countries as well. These results suggest the importance of developing a more robust theoretical, conceptual and methodological framework. Consequently, the guides need to be more accurate and should be continuously updated. Our results are valuable for the EDP actors and have policymaking implications".

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.

Unanswered questions and unquestioned answers: the challenges of crop residue retention and weed control in Conservation Agriculture systems of southern Africa

Christian Thierfelder Blessing Mhlanga Hambulo Ngoma Paswel Marenya Md Abdul Matin Adane Tufa (2024, [Artículo])

Production and utilization of crop residues as mulch and effective weed management are two central elements in the successful implementation of Conservation Agriculture (CA) systems in southern Africa. Yet, the challenges of crop residue availability for mulch or the difficulties in managing weed proliferation in CA systems are bigger than a micro-level focus on weeds and crop residues themselves. The bottlenecks are symptoms of broader systemic complications that cannot be resolved without appreciating the interactions between the current scientific understanding of CA and its application in smallholder systems, private incentives, social norms, institutions, and government policy. In this paper, we elucidate a series of areas that represent some unquestioned answers about chemical weed control and unanswered questions about how to maintain groundcover demanding more research along the natural and social sciences continuum. In some communities, traditional rules that allow free-range grazing of livestock after harvesting present a barrier in surface crop residue management. On the other hand, many of the communities either burn, remove, or incorporate the residues into the soil thus hindering the near-permanent soil cover required in CA systems. The lack of soil cover also means that weed management through soil mulch is unachievable. Herbicides are often a successful stopgap solution to weed control, but they are costly, and most farmers do not use them as recommended, which reduces efficacy. Besides, the use of herbicides can cause environmental hazards and may affect human health. Here, we suggest further assessment of the manipulation of crop competition, the use of vigorously growing cover crops, exploration of allelopathy, and use of microorganisms in managing weeds and reducing seed production to deplete the soil weed seed bank. We also suggest in situ production of plant biomass, use of unpalatable species for mulch generation and change of grazing by-laws towards a holistic management of pastures to reduce the competition for crop residues. However, these depend on the socio-economic status dynamics at farmer and community level.
