    Stability-Aware Security–Performance Trade-Off Analysis in Resource-Constrained IoT Systems: A Time-Series and Bootstrap-Based Evaluation of TLS and Hybrid ECC–AES Mechanisms

    The increasing deployment of resource-constrained Internet of Things (IoT) devices requires security mechanisms that preserve confidentiality without compromising energy efficiency or responsiveness. Although Transport Layer Security (TLS) provides standardized protection for MQTT-based communication, its computational overhead may significantly affect embedded architectures. This study presents a controlled experimental evaluation of three communication configurations implemented on ESP32-based nodes: unencrypted Message Queuing Telemetry Transport (MQTT), MQTT over TLS 1.2, and an application-layer hybrid scheme combining Elliptic Curve Diffie–Hellman key exchange with AES-128 encryption. Second-level measurements of instantaneous current, accumulated energy, end-to-end latency, and memory footprint were collected across repeated experimental runs. Time-series diagnostics were performed to assess autocorrelation and stationarity, and block bootstrap resampling was applied to ensure dependence-aware statistical inference. The results indicate that TLS introduces the highest cumulative energy growth and latency dispersion, while the hybrid ECC–AES configuration demonstrates intermediate behavior with reduced overhead relative to TLS. Pareto frontier analysis shows that TLS is dominated in the joint energy–latency space, whereas the hybrid scheme represents a non-dominated compromise between security and efficiency. These findings provide a stability-aware and statistically robust framework for evaluating security–performance trade-offs in embedded IoT systems.

    Small Doses of Entrepreneurial Content (SDEC) to Foster Entrepreneurial Competencies in Biotechnology Engineering

    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.

    El consentimiento en la Nueva España : la fundamentación de la igualdad de Alonso de la Veracruz.
    (Editorial NUN, 2025)
    ;
    Hernández Godoy Zara
    El objetivo de este trabajo es subrayar la relevancia de la argumentación de Alonso de la Veracruz en el siglo XVI respecto a la necesidad del consentimiento matrimonial por parte de la mujer y las implicaciones antropológicas que esto conlleva. Con este fin, iniciaremos con un breve contexto histórico y cultural del consentimiento matrimonial en occidente. En primer lugar, expondremos el patriarcado cultural milenario en occidente. En segundo lugar, el escándalo que supuso el cristianismo con respecto a la valoración de la mujer como persona. En tercer lugar, abordaremos el ambivalente reencuentro del Derecho romano en Bolonia y el resurgimiento de la filosofía aristotélica, como una diacrónica caja de Pandora que permeó a los filósofos medievales a través de las primeras universidades. Lo anterior permitirá concluir la originalidad de la intuición antropológica de Alonso de la Veracruz sobre la incondicional igualdad en dignidad entre hombre y mujer a través de su argumentación filosófica sobre el consentimiento matrimonial en el siglo XVI.

    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.

    The Essence of Hospitality Extracted from the Odyssey of Homer: Its Relevance for Hospitality Professionals Today
    (Springer International Publishing, 2022)
    Saul, Fabiola
    It seems an undeniable fact that hospitality as the generous action of receiving someone, usually a stranger, in the home has been a millenary practice. This may have to do with the fact that man possesses the capability to move around the earth, and therefore when he is in a foreign land, he may need shelter or refuge. In this context, many authors have considered Homer’s poem, the Odyssey, a good setting to study this phenomenon, since it is the remotest testimony of a great journey, in Western Literature, one in which Odysseus takes 10 years to return home. An author that complements the study of Homer is Aristotle, since his theory of virtue offers a possible conception of hospitality as a human trait that is acquired through effort and models a person’s moral character towards the good. This chapter tries to unite both Greek authors to find the essence of hospitality and, from there, the possible implications for today’s hospitality professionals. ©The author ©Springer.

    A Stemma of Sigurgarðs saga frækna, and a Case Study of Saga-Anthologization

    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.
