Zara was founded in 1975 by Amancio Ortega Gaona, soon becoming the largest and most successful chain of the Galician group Inditex (Industria de Diseño Textil) and a pioneer of the rising fashion category of Fast Fashion. Its innovative vertically-integrated strategies, combined with its emphasis on quality and demand-based offer have shaped the world of fashion and brought forth many questions on its future sustainability and growth. Zara has always relied on its store network for advertising its product offer; allowing its garments to “speak for themselves”. With the continued pressure felt in the industry, management has pressed some concerns about future company growth and creative, innovating solutions must be implemented to guarantee Zara’s future growth. The case-study narrative focuses on these issues and leaves readers with an open question regarding what decision to implement.

The study of AC losses in superconducting pancake coils is of utmost importance for the development of superconducting devices. Due to different technical difficulties this study is usually performed considering one of two approaches: considering superconducting coils of few turns and studying AC losses in a large frequency range vs. superconducting coils with a large number of turns but measuring AC losses only in low frequencies. In this work, a study of AC losses in 128 turn superconducting coils is performed, considering frequencies ranging from 50 Hz till 1152 Hz and currents ranging from zero till the critical current of the coils. Moreover, the study of AC losses considering two different simultaneous harmonic components is also performed and results are compared to the behaviour presented by the coils when operating in a single frequency regime. Different electrical methods are used to verify the total amount of AC losses in the coil and a simple calorimetric method is presented, in order to measure AC losses in a multi-harmonic context. Different analytical and numerical methods are implemented and/or used, to design the superconducting coils and to compute the total amount of AC losses in the superconducting system and a comparison is performed to verify the advantages and drawbacks of each method.

La thèse que nous soutenons et que nous nous proposons de démontrer dans cet article est que la crise, chez Ortega y Gasset, loin d’instituer une rupture dans le processus de l’histoire, et de menacer ainsi sa continuité, en est la condition de possibilité. L’hypothèse que nous nous proposons de vérifier est que l’idée même d’un « sens » de l’histoire – nous reviendrons sur la manière bien particulière dont le philosophe madrilène entend cette expression – est garantie par la crise. Nous explorerons pour cela très précisément la tension qui réside entre l’affirmation ortéguienne selon laquelle la crise est le moteur de l’histoire d’une part, et la description à laquelle procède le philosophe madrilène de l’homme en crise comme acteur de l’histoire paralysé d’autre part.
