Entrepreneurial universities emphasize teaching, research, and community outreach, with entrepreneurial education playing a vital role in fostering an entrepreneurial culture and achieving social and economic impact. While entrepreneurial education is well-established in business programs, its integration into non-business disciplines, such as engineering, presents unique challenges, including aligning entrepreneurial content with technical curricula and measuring outcomes effectively. This study examines the impact of delivering Small Doses of Entrepreneurial Content (SDEC) on senior biotechnology students' key entrepreneurial competencies-decision-making, resilience, and opportunity recognition. The SDEC was integrated into a course through a “Learning Kit” comprising lectures, workshops, entrepreneurial talks, and project evaluations. Using a pre-and post-intervention design with validated scales and statistical analyses, the study revealed significant gains in specific decision-making and opportunity recognition skills, particularly among students with prior entrepreneurial exposure. This research contributes to the literature by addressing the challenges of designing entrepreneurial education in non-business disciplines and offering a scalable, transversal approach that complements technical curricula. The findings underscore the potential for embedding entrepreneurial education across diverse disciplines and provide a practical reference for educators seeking to implement such interventions effectively.

Expresiones de la ética científica en Twitter/X: un análisis de co-ocurrencia de hashtags
(Universitat Autonoma de Barcelona, 2026-01-06)
;
;
Esta investigación tiene un objetivo doble: primero, determinar en qué medida los temas de la ética científica y la integridad académica se han expresado en Twitter/X; segundo, revelar y profundizar en los tópicos que se generar sobre estas temáticas centrales y, con ello, analizar la dinámica de los principales usuarios que se insertan en éstas. Para tal fin, se conformó una base de datos con poco más de 201 mil tweets que usaron al menos uno de 22 términos definidos y relacionados con los temas principales. La unidad fundamental de análisis fueron los hashtags que se usan dentro de los tweets. Además, aplicamos el enfoque del análisis de redes sociales para revelar y entender cómo están conectados entre sí. Los resultados muestran que el tema de la ética científica está bien expresado en Twitter; también, que se han usado una gran diversidad de hashtags, que dan forman a diferentes ejes temáticos. Adicionalmente, los usuarios tienen distintos roles asociados a los hashtags. Se concluye demostrando que Twitter es un buen espacio para la expresión de la ética científica; sin embargo, existen vertientes tanto positivas como negativas al respecto.

This article publishes the first stemma of the manuscripts of the fifteenth-century Icelandic romance Sigurgarðs saga frækna, taking in 58 of the 61 known witnesses. It capitalizes on digitally-native publication to publish all underlying data, presenting a fully open-data approach to stemmatics. The article shows how the post-medieval transmission of the saga supports previous claims about how Icelandic sagas in this genre circulated but also takes manuscripts containing Sigurgarðs saga frækna produced in the seventeenth to nineteenth centuries in the Dalir region of Iceland as a case study for a methodologically novel investigation of how scribes went about anthologization. Refining previous work on the manuscript filiations of Ambrósíus saga og Rósamundu, Sigurðar saga turnara, Hálfdanar saga Eysteinssonar, Nítíða saga, and Konráðs saga keisarasonar, and making the first outline of a stemma of Nikulás saga leikara, the study gives our first systematic insight into how the scribes of the eighteenth-century manuscript Rask 32 assembled their anthology, and how their work influenced subsequent anthologies that drew material from that manuscript.

Hackathons for Social Design: A Co-Creation Model for Sustainable Innovation
(Jomard Publishing, 2026-04-02)
;
Resendiz Ramirez Ximena
This article analyzes a social design hackathon held in Guadalajara, Mexico, in 2023, as a co-creation methodology aimed at sustainable innovation and water management. The purpose of the study is to evaluate how social design and design thinking can generate technological solutions for environmental challenges through collaboration among academia, government, the private sector and civil society. The study employs a qualitative case study methodology based on direct observation, document review and participant interviews. The hackathon brought together 14 interdisciplinary teams that proposed solutions using technologies such as IoT sensors, machine learning and data analysis. The results show the generation of viable proposals but highlight the limited participation of civil society and the need for more structured corporate involvement. The study concludes that social design, when integrated with Corporate Social Responsibility (CSR) and open innovation principles, can be a powerful tool for sustainable development, especially within a quadruple helix model that strengthens multisector collaboration.

Brazil’s National Power Evolution and Geostructural Positioning
(Springer Nature Singapore, 2025)
Ruvalcaba, Daniel Morales
;
Apango Partida, Mónica
This chapter examines Brazil’s national power’s evolution and geostructural positioning in the international system since the end of the Cold War. From a methodological perspective, a theoretical approach is adopted, conceptualising national-international power as a multidimensional, dynamic, and recursive combination of capacities. The analysis is based on the use of the World Power Index (WPI), a quantitative tool that allows for the measurement and comparison of Brazil’s power over time, providing an empirical basis for understanding its trajectory. Within this framework, the material, semimaterial, and immaterial capacities that have defined the configuration of its national power are assessed. The chapter is organised into four main sections. The first provides a historical review of Brazil’s national power, contextualising its position as a semiperipheral country in the global system. The second analyses the evolution of Brazilian power since the end of the Cold War, identifying a cycle characterised by short phases of rise and decline (1990–2002), a prolonged phase of emerging consolidation (2003–2011), and, subsequently, a sustained period of decline that began in 2012 and started to reverse from 2021 onward. The third section presents a diachronic analysis of Brazil’s material, semimaterial, and immaterial capacities. Finally, the fourth section examines its geostructural positioning at both regional and global levels, exploring its main roles as a regional power with global aspirations. The academic importance of this chapter lies in its innovative analysis of Brazil’s national power, which combines a historical and quantitative approach with a comprehensive perspective on power. This approach enables an understanding of how Brazil has balanced its regional leadership with its insertion into the international system while transiting cycles of rise and decline in its national power.

This paper presents the analysis, design, and experimental validation of a Partial Power Processing (PPP) Single-Ended Primary Inductor Converter (SEPIC) for photovoltaic (PV) applications. The proposed topology limits the fraction of processed power through the active switching stage, thereby reducing MOSFET RMS current and associated conduction losses and improving overall conversion efficiency. A complete analytical framework is developed, including steady-state modeling, state-space formulation, and small-signal analysis. The theoretical results are validated through MATLAB/Simulink simulations and laboratory-scale experimental tests under multiple loading conditions. Comparative analysis against a conventional Full Power Processing (FPP) SEPIC converter demonstrates that the proposed PPP configuration achieves efficiencies up to 95% in simulation and up to 93% experimentally, compared to 87% for the FPP counterpart under identical nominal conditions (𝑉in =18 V, 𝑓s =70 kHz). Additionally, the PPP approach reduces the MOSFET RMS current by more than 50%, which directly translates into lower conduction losses and reduced device power dissipation. The results confirm that the proposed PPP-SEPIC converter constitutes a technically viable and energy-efficient solution for photovoltaic DC–DC power conversion systems.

Be super, be white: perceptions of representation and inclusion in superhero films from a Mexican audience
(Informa UK Limited, 2026-03-26)
;
;
Montaño Rodriguez, Luis Fernando
This study examines young Mexicans’ perceptions of representation in superhero films, revealing a paradox: While advocating for diversity, the films reinforce whiteness as the norm for representation. Using Stuart Hall’s identity framework, the findings highlight how Hollywood’s dominance and Mexico’s pigmentocracy shape audience views. Participants concluded that inclusion is accepted in secondary roles but perceived as forced when it comes to main characters, and authenticity is tied to cultural fidelity (and stereotypical representation) rather than racial diversity. Ultimately, superhero films sustain whiteness as the aspirational standard in Mexican and global media.

A feasibility-based framework for decentralized urban growth in megacity regions

Rapid metropolitan growth in water-stressed megacity regions has renewed interest in decentralized urban development, yet such strategies often overlook binding environmental and legal constraints. This study applies a feasibility-screening framework to evaluate decentralized growth potential in the Guadalajara Metropolitan Area (GMA), Mexico, using a sequential, non-compensatory approach based on necessary conditions rather than composite sustainability indices. Transport connectivity, population and territorial context, food production capacity, and integrated water availability are assessed for three candidate municipalities. While all cases satisfy the structural and contextual conditions, the results indicate that water availability constitutes the dominant limiting factor when physical supply and legal accessibility are jointly considered. Only one municipality meets the water feasibility criterion under current conditions, whereas the others fail despite favorable performance in other dimensions. The framework provides a transferable tool for early-stage urban planning in water-constrained megacity regions.

Social network analysis and narrative structures: measuring communication and influence in a Medieval source for the Kingdom of Sicily
(El Colegio de Jalisco, 2017-08-31)
Análisis de redes sociales y estructuras narrativas: Midiendo comunicación e influencia en una fuente Medieval para el Reino de SiciliaEl artículo presenta la reflexión metodológica y los resultados del enfoque que he aplicado para comprender los procesos sociales y políticos presentes en una fuente textual. El tema sobre el que se fundó el estudio fueron las interacciones entre los actores sociales tal como se desarrollan en una narrativa histórica. Un enfoque relacional puede contribuir a la comprensión de las narrativas y su utilidad histórica, y las dos preguntas principales rectoras de mi investigación fueron: 1) ¿Cómo extraer datos relacionales y construir redes que representan la información contenida en una fuente narrativa; Y 2) ¿qué nos dicen las redes así construidas sobre el significado y las implicaciones del espacio social presente en el mensaje? Con el fin de concentrarme en la información sociológicamente relevante que el texto ofrece, ’traduje' un informe retórico en un conjunto relacional de datos. El primer paso de este esfuerzo consistió en trasladar una estructura textual en una construcción sociológica, es decir, en un conjunto de datos socio-relacionales. Los conjuntos de datos narrativos proporcionaron una serie de sociomatrices narrativas listas para ser analizadas a través de herramientas analíticas de redes. De éstos, el uso e interpretación de las medidas de centralidad resultó ser uno de los enfoques más fructíferos para comprender las dimensiones sociales del texto. Medidas de centralidad y prestigio resultaron útiles al explorar las interacciones narrativas de comunicación e influencia social. Este estudio intenta demostrar que, a través de un enfoque relacional, se puede superar la brecha entre los puntos de vista cognitivo y estructural y, por lo tanto, avanzar hacia una mejor comprensión de las construcciones sociales 'entre líneas’ de una fuente histórica textual.
