Much has been written In English about the experiences and treatment of immigrants from south of the Rio Grande once they have entered the United States. But this account, by the itinerant, effervescent and highly original journalist Belen Fernandez, offers a different and wholly original take. Belen Fernandez shows us what life is like for would-be migrants, not just from the Mexican side of the border but inside Siglo XXI, the notorious migrant detention center in the south of the country. Journalists are prohibited from entering Siglo XXI; Fernandez only gained access because she herself was detained as a result of faulty paperwork when she attempted to return to the US to renew her passport. Once inside the facility, Fernandez was able to speak with detained women from Honduras, Cuba, Haiti, Bangladesh, and beyond. Their stories, detailing the hardships that prompted them to leave their homes, and the dangers they have experienced on an often-tortuous journey north, form the core of this unique book. The companionship and support they offer to Fernandez, whose antipathy to returning to the United States, the country they are desperate to enter, is a source of bemusement and perplexity, demonstrates a spirited generosity that is deeply moving. In the end, the Siglo XXI center emerges as a strikingly precise metaphor for a 21st century in which poor people, effectively imprisoned by American political and economic policies, nevertheless display astonishing resilience.

"When I first committed to three full months in El Salvador, the feeling that I was signing up for the equivalent of marriage and reproduction was assuaged only by the awareness that, come March 2020, I'd be dashing around Mexico before flying to Istanbul and resuming freneticism in that hemisphere. Little did I know that the scribbled itinerary would never come to fruition, and that I'd only get as far as the coastal village of Zipolite in the Mexican state of Oaxaca, where March 13-25 would turn into March 13 until further notice." Since leaving her American homeland in 2003 Belen Fernandez had been an inveterate traveler. Ceaselessly wandering the world, the only constant in her itinerary was a conviction never to return to the country of her childhood. Then the COVID-19 lockdown happened and Fernandez found herself stranded in a small village on the Pacific coast of Mexico. This charming, wryly humorous account of nine months stuck in one place nevertheless roams freely: over reflections on previous excursions to the wilder regions of North Africa, Asia and Eastern Europe; over her new-found friendship with Javier, the mezcal-drinking, chain-smoking near-septuagenarian she encounters in his plastic chair on Mexico's only clothing-optional beach; over her protracted struggle to obtain a life-saving supply of yerba mate; and over, literally, the rope of a COVID-19 checkpoint, set up directly outside her front door and manned by armed guards who require her to don a mask every time she returns home.

The book "TransMath - Innovative Solutions from Mathematical Technology" has been conceived as a tool for the dissemination of scientific knowledge. This publication is addressed to those companies with innovation needs that could be met through mathematical technology. The book maps both existing and possible interactions and connections that enable technology transfer between Spanish mathematical research and industrial and business sectors. Businesses can determine the level of implementation and demand for such technology within their sector and understand the benefits and innovations achieved in other companies and industries with the application of mathematical techniques. The information is classified into eleven sectors of economic activity: Biomedicine & Health; Construction; Economics & Finance; Energy & Environment; Food; ICT; Logistics & Transport; Management & Tourism; Metal & Machinery; Public Administration; and Technical Services.
