Sustainability in Fashion Industry: A View Through the Top Ten Multinational Strategies
No full text[EN]Climate change threatens the future of the next generations and is already causing widespread destruction in the present through an increasing number of natural disasters. A new model of production and consumption based on sustainability is required, especially in the fashion industry—the second most polluting sector in the world. Therefore, in order to determine whether these companies contribute to people’s and the planet’s well-being, it is necessary to understand their practices. To this end, we analyse the sustainable practices of the sector by studying the ten most responsible fashion companies according to the BoF Sustainability Index, that is based on the methodology of content analysis applied to case studies. To do this, we have defined a taxonomy of the ten most common sustainability strategies and practices: stakeholder engagement, strong governance and transparency, decarbonisation, biodiversity conservation and restoration, circularity, reducing waste and pollution from the use of plastics, eliminating hazardous chemicals, preserving water quality, diversity, equity and inclusion policies, supply chain responsibility, and supporting the communities in which companies operate. The results show that major business groups have integrated axes into their sustainability strategies that address the industry’s primary social and environmental challenges. These plans are based on ambitious goals that go beyond stakeholder demands and the generation of economic benefits.This work is part of the R&D&I project PID2024-155692NB-I00 funded by MICIU/AEI/10.13039/501100011033 and by ERDF/EU.

Thermo-economic optimization of an adiabatic compressed air energy storage system including system dynamics
No full text[EN]Adiabatic compressed air energy storage is a promising, in-development technology for storing renewable
energy, for instance, from wind parks or photovoltaic installations. This work presents a multi-objective
thermoeconomic optimization analysis. It is based on a dynamic model of the plant’s thermodynamic
performance, in which the dynamics of the thermal energy storage (packed-bed type) and the charge and
discharge processes of the air reservoir are solved in detail. A plant configuration, as determined from
previous work in our group, with a priori good round-trip efficiencies (around 0.76–0.78), is considered the
starting point. It encompasses two-stage compression and expansion trains, along with two radial packedbeds
(utilizing either sensible or phase-change materials) to capitalize on the cooling between compression
steps. In the developed optimization procedure, the levelized cost of storage (LCoS) and the total capital
expenditure (CAPEX) are taken as key performance indicators. The decision variables include, among others,
mass flows, thermal energy storage dimensions, maximum and minimum cavern pressures, and the symmetry
of the pressure ratios between compressors and turbines. The optimization procedure uses an NSGA-II genetic
algorithm. One of the main novelties of the work is that accurate dynamic simulations have been used to obtain
Pareto fronts. They are analyzed from different perspectives: the size, geometry, and materials of the packedbeds;
the type of compressor (axial or centrifugal); energetic factors such as input and output energy and power;
the maximum pressures in the cavern; and the mass flows in the charge and discharge processes. Values of
LCoS are calculated with precision using realistic input data, resulting in approximately 80 e/MWh for a plant
capable of storing 600 MWh (reference power of 200 MW for charge periods of 3 h) and electricity prices during
charge of 50 e/MWh. The specific parameters and configurations that lead to those LCoS levels are made
explicit. Furthermore, the influence of cavern costs, charging electricity prices, and idle time is analyzed in
detail.Fondo Social Europeo Plus and Consejería de Educación de la Junta de Castilla León under their Ph.D. grant program (EDU/1868/2022).

Fabricar la crisis, gobernar la inestabilidad: la ecología política de la migración, el poder y el ecocidio
No full text[EN]Human mobility is not an anomaly but a historical constant that has been systematically gov- erned, stratified and racialised. This article reconceptualises the “migration crisis” not as an exceptional event but as a political-ecological crisis regime that manufactures crisis, organises instability and legitimises violence at and beyond borders. Bringing together political ecology, world-ecology, governmentality and debates on racial capitalism, it develops a framework for analysing how war, extractivism, ecocide and climate apartheid produce unliveable environments and stratified regimes of (im)mobility. The argument is operationalised through paradigmatic cases from the Ecuadorian Amazon, the Niger Delta, Gaza, the Kafue basin and ar- chitectures of climate apartheid, showing how legal, economic and humanitarian infrastructures manufacture dispossession, immobilisation and selective mobility. By treating crisis as a durable regime rather than an episode, the article links border spectacles to slower forms of environmental and colonial violence and clarifies how migrants’ lives are governed as a managed instability. [ES]La movilidad humana no es una anomalía, sino una constante histórica que ha sido sistemáticamente gobernada, estratificada y racializada. Este artículo reconceptualiza la “crisis migratoria” no como un acontecimiento excepcional, sino como un régimen de crisis político-ecológica que fabrica la crisis, organiza la inestabilidad y legitima la violencia en y más allá de las fronteras. A partir de la ecología política, la ecología-mundo, la gubernamentalidad y los debates sobre capitalismo racial, desarrolla un marco analítico para examinar cómo la guerra, el extractivismo, el ecocidio y el apartheid climático producen entornos invivibles y regímenes estratificados de (in)movilidad. El argumento se operacionaliza mediante casos paradigmáticos de la Amazonía ecuatoriana, el delta del Níger, Gaza, la cuenca del Kafue y las arquitecturas del apartheid climático, mostrando cómo las infraestructuras jurídicas, económicas y humanitarias producen desposesión, inmovilización y movilidad selectiva. Al tratar la crisis como un régimen duradero más que como un episodio, el artículo vincula los espectáculos fronterizos con formas más lentas de violencia ambiental y colonial y esclarece cómo las vidas de las personas migrantes se gobiernan como una inestabilidad gestionada

Quality vs. populism in short-video political communication: a multimodal study of TikTok
No full text[EN]The article examines how framing and actor identity structure attention in short-video
politics using a country-level corpus from Ecuador. It assembles 4612 public TikTok videos
from official accounts and politically salient hashtags, extracts multimodal text via automatic
speech recognition and on-screen OCR, and constructs two continuous indices: a
quality index (programmatic, efficacy-oriented content) and a populism index (antagonistic,
people-versus-elite cues). Engagement is modeled as a fractional response (binomial GLM
with logit link), with robustness checks using OLS on logit(ER) and Poisson counts with an
offset for log(plays + 1). Models include affect (positive sentiment and anger), hour/day
controls, and actor fixed effects (leader, creator, institution, party, and media). The indices
display construct validity: quality aligns with positive/joyful tone and populism with anger.
Net of controls, populism is positively and consistently associated with engagement across
estimators; quality is small and often null or negative. Effects are heterogeneous: leaders
gain under both frames, creators primarily under populism, and media modestly under
populism, while institutions face penalties under both, and parties show limited returns.
Monthly series reveal event-linked intensification of populism, and hashtag networks are
modular, mapping onto institutional, partisan, and creator ecosystems. A design analysis
identifies a non-populist pathway—benefit-first micro-explanations, concise captions, targeted
hashtags, and joyful/efficacy affect—that raises engagement without antagonism.
The study contributes a reproducible, open-source pipeline for survey-free, multimodal
framing measurement and clarifies how persona × frame interactions and meso-level
discursive structure jointly organize attention in short-video politics
Translating His‑stories
No full text[ENG] Following Hayden White and the critical historiography of the 1960s, the idea underlying this Element is that a historical text is a translation of past events. This implies that retelling stories can vary depending on the historian/translator who recounts the facts. Translating His-stories focuses on how women – Jen Bervin, Patience Agbabi, Caroline Bergvall, Erin Mouré, and many others – dare to translate stories previously told by men. In line with contemporary theories of translation, these stories are translations because women rewrite, again but for the first time, what has already been told.
[SPA] Siguiendo a Hayden White y la historiografía crítica de la década de 1960, la idea subyacente a este Elemento es que un texto histórico es una traducción de acontecimientos pasados. Esto implica que la narración de historias puede variar según el historiador/traductor que relata los hechos. Translating His-stories se centra en cómo las mujeres —Jen Bervin, Patience Agbabi, Caroline Bergvall, Erin Mouré y muchas otras— se atreven a traducir historias previamente contadas por hombres. En consonancia con las teorías contemporáneas de la traducción, estas historias son traducciones porque las mujeres reescriben, de nuevo pero por primera vez, lo ya contado
Cinematography as a Transmitter of Pictorial Imagery in Filmmaking
No full text[EN] Strictly speaking, we must consider that a film constructs images. We know that humans have been creating them for almost two thousand years, so it seems logical to assume that the cinematic image should maintain a relationship with the visual legacy that has preceded it. The concatenation of mental constructions in pictorial images has developed over the years, with the flat images of ancient societies giving way to more complex and vivid representations in both the second half of the Middle Ages and the Renaissance, taking the imagination to unprecedented levels. It was from the Baroque period onwards that the era of exuberance arrived, giving rise to what would come next, the -isms, which would help to complete the foundations of the fundamental elements of study in this work: framing; light and, consequently, color; textures and atmospheres
