Urban Forest Tweeting: Social Media as More-Than-Human Communication in Tokyo’s Rinshinomori Park

Urban parks are places that have significant impact on the physical and mental health of citizens, but they are also for safeguarding biodiversity and thus fostering human–nature interactions in the everyday landscape. The exploration of these spaces through social media represents a novel field of research that is contributing to revealing patterns of visitor behavior. However, there is a lack of comparable research from a non-anthropocentric perspective. What if we could use social media as a more-than-human communication medium? This research aims to reveal the possibility of communicating the urban forest’s voice through the examination of the official Twitter account of a metropolitan park in Tokyo. To this end, an analysis of the content of the messages is carried out, focusing on the narrative voice from which the message is told, the protagonists, the action performed, the network of actors deployed, and the place where it occurs. It is found that the majority of these messages are delivered from a non-human perspective, where plants, animals, or meteorological agents behave deploying complex networks of more-than-human interaction. The current study reveals the latent potential of non-humans as possible agents within the realm of social media, which can mediate the relationships between humans and their environment. It introduces a layer that can be incorporated into future lines of research, as well as provides a model case that illustrates a good practice in the management and communication of urban green spaces.This research was funded by the European Union—Next Generation EU Margarita Salas Grant and by the project LABPA-CM: CONTEMPORARY CRITERIA, METHODS and TECHNIQUES FOR LANDSCAPE KNOWLEDGE AND CONSERVATION (H2019/HUM5692), funded by the European Social Fund and the Madrid regional government

Vivienda Transcultural. La arquitecta japonesa pionera Miho Hamaguchi y su último proyecto en España

Miho Hamaguchi (1915-1988) was the first woman to be a licensed architect in Japan. A pioneer in domestic design during the postwar period, she built and consulted on thousands of houses throughout her prolific career. However, she is a little-known figure both in Japan and in the international debate. Her representation in architectural historiography is limited to her influence on kitchen design, but her writings and work go far beyond. Hamaguchi's legacy is one of bold residential architecture that embodied democratic ideas in spatial configurations. She promoted the house as a fundamental tool for gender equality, leaving behind a feudal and patriarchal system. At the end of her career, she found in Costa del Sol the perfect place to carry out a residential project as a cultural exchange. "Kaiyo Club" became a set of three houses since the first design in 1974 until the subsequent extensions were completed in 1987. Throughout its different stages, the project shows a striking Spanish-Japanese transfer where different architectural languages coexist. The white-walled exterior dialogues with the vernacular, while its interior unfolds Japanese patterns with tatami-floored rooms or ofuro-style bathrooms. These dwellings present a unique hybrid materialization, displaying Hamaguchi's design from a humanistic stance, blending of locally rooted modernist spatial principles and reinterpreted traditions.Miho Hamaguchi (1915-1988) fue la primera arquitecta licenciada en Japón.

Dissipative stabilization of maximal entanglement between non-identical emitters via two-photon excitation

We study the generation of nearly maximal stationary entanglement between two non-identical quantum emitters embedded in a cavity and coherently excited at the two-photon resonance, i.e., with half of the energy of the doubly excited state. We report a mechanism that arises when the emitters interact forming a dimer and the cavity linewidth is small enough to resolve their internal excitonic structure. This condition gives rise to a frequency-dependent Purcell effect which results into two resonant conditions for the cavity frequency. At each resonance, we observe a nearly maximal steady-state occupation of either the symmetric or antisymmetric combination of one-excitation qubit states. This mechanism is optically tunable and leads to significantly greater and faster stationary entanglement than the resonant excitation of the transition from the ground state to the symmetric or antisymmetric states, reported in previous works. By exploring the parameter space of the system, we show that this phenomenon is one of a family of effects that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance. We provide a global perspective of this landscape of mechanisms and contribute analytical descriptions and insights into these phenomena, establishing connections with previous reports in the literature and discussing how some of these effects can be optically detected

Frequency-resolved Purcell effect for the dissipative generation of steady-state entanglement

We report a driven-dissipative mechanism to generate stationary entangled $W$ states among strongly-interacting quantum emitters placed within a cavity. Driving the ensemble into the highest energy state -- whether coherently or incoherently -- enables a subsequent cavity-enhanced decay into an entangled steady state consisting of a single de-excitation shared coherently among all emitters, i.e., a $W$ state, well known for its robustness against qubit loss. The non-harmonic energy structure of the interacting ensemble allows this transition to be resonantly selected by the cavity, while quenching subsequent off-resonant decays. Evidence of this purely dissipative mechanism should be observable in state-of-the-art cavity QED systems in the solid-state, enabling new prospects for the scalable stabilization of quantum states in dissipative quantum platforms.Comment: 5 pages, 3 figures, Supplemental Material with 8 pages, 5 figure

Quality of Life in Teenagers and Adults With Coeliac Disease: From Newly Spanish Coeliac Disease Questionnaire Validation to Assessment in a Population-Based Study

Background: Coeliac disease (CD) is an immune-mediated systemic disorder elicited by the ingestion of gluten in genetically predisposed individuals. Gluten restriction in CD sufferers leads to numerous limitations in various aspects of daily life and can significantly impact the quality-of-life (QoL). The specific and widely used Coeliac Disease Questionnaire (CDQ) is an excellent tool to evaluate QoL in patients with CD, assessing physical, psychological, and social domains. This questionnaire is unavailable in Spain. Therefore, our study is the first to translate, culturally adapt, validate, and apply the Spanish version of CDQ to a representative sample of Spanish teenagers and adults with CD. Methods: A total of 153 CD participants with biopsy-proven and self-reported gluten-free adherence were included in the cross-sectional study, which included four stages: (1) translation and retranslation of the French CDQ version into Spanish; (2) cultural adaptation and semantic evaluation; (3) CDQ validation through the internal consistency determination and reproducibility of the QoL; and (4) application of the questionnaire to Spanish teenagers and adults with CD and estimation of QoL using EQ-5D. Results: The internal consistency and test–retest reliability of the Spanish CDQ were satisfactory and no ceiling or floor effects were detected. Significant correlations were identified between the CDQ scales, and the instrument for validation covering similar dimensions of the QoL was identified. The mean CDQ total score was 131.03 ± 24.1, and the social domain had the highest rating. There was no correlation between the time spent on a gluten-free diet and QoL. A significantly higher QoL score was reported among males and adolescents in the 15–17 age groups. Conclusion: The newly Spanish CDQ is an appropriate tool to assess the QoL of the teenager and adult patients with CD. This study highlights the importance of identifying the affected scales to address actions to reduce the impact of the gluten-free diet burden of the coeliac patients and maintain public health regulations that support patients with chronic diseases such as CDCentro para el Desarrollo Tecnologico Industrial 20/0112Corporación Tecnológica de Andalucía 20/011

Field trips and other teaching resources in natural and social sciences: educational implications from past experiences in Spanish primary schools

[EN] This paper describes the use of Natural and Social Sciences teaching resources in Spanish primary schools during the second half of the 20th century, based on quantitative and qualitative analysis of 250 recollections of retired teachers. Differences were identified between groups of teachers determined by gender, previous teaching context (urban vs rural) and higher education qualifications. Our results show that the academic background had a direct impact on the variety and type of teaching resources used and was a determinant factor to promote experiential learning. The study also highlights the comprehensive use of school field trips in the past as teaching resources to motivate students and develop different inquiry skills. Finally, the importance of mastering different educational resources in the teaching profession is discussed.This study is part of the Project Estudio y análisis de la cultura escolar a través de los testimonios de docentes (REF K117), funded by the University of Salamanca

Single-photon source over the terahertz regime

We present a proposal for a tunable source of single photons operating in the terahertz (THz) regime. This scheme transforms incident visible photons into quantum THz radiation by driving a single polar quantum emitter with an optical laser, with its permanent dipole enabling dressed THz transitions enhanced by the resonant coupling to a cavity. This mechanism offers optical tunability of properties such as the frequency of the emission or its quantum statistics (ranging from antibunching to entangled multi-photon states) by modifying the intensity and frequency of the drive. We show that the implementation of this proposal is feasible with state-of-the-art photonics technology.Comment: 18 pages, 14 figure

First Data from the Prehistoric Site Complex of Cueva del Arco (Murcia, Spain)

The southern Iberian Peninsula is a key area for understanding the timing and patterns of the Middle-to-Upper Palaeolithic transition. Recently, the excavation and study of new sites have provided new insights on this topic. The aim of this paper is to introduce Cueva del Arco, a site complex featuring distinct caves and rock shelters. Cueva del Arco is located at a short distance from the Almadenes gorge (Cieza, Spain) and preserves both Middle and Upper Palaeolithic deposits and assemblages, as well as rock art. Despite being known since the 1990s for its Palaeolithic rock art, systematic fieldwork was never undertaken at the site until recently. We here report the first results of a research programme that includes the systematic excavation of several cavities belonging to the Cueva del Arco complex, focusing on the location and context of the site, its stratigraphy and chronology, and site formation. Research at the site is still ongoing, but preliminary results suggest that the data from Cueva del Arco will provide new clues to the current debate on the transition from Neanderthals to anatomically modern humans in southern Europe
