Fashioning Spain is a cultural history of Spanish fashion in the 20th and 21st centuries, a period of significant social, political, and economic upheaval. As Spain moved from dictatorship to democracy and, most recently, to the digital age, fashion has experienced seismic shifts. The chapters in this collection reveal how women empowered themselves through fashion choices, detail Balenciaga’s international stardom, present female photographers challenging gender roles under Franco’s rule, and uncover the politicization of the mantilla. In the visual culture of Spanish fashion, tradition and modernity coexist and compete, reflecting society’s changing affects.Using a range of case studies and approaches, this collection explores fashion in films, comics from la Movida , Rosalía’s music videos, and both brick-and-mortar and virtual museums. It demonstrates that fashion is ripe with historical meaning, and offers unique insights into the many facets of Spanish cultural life.

An exploration of how contemporary art reframes and humanizes migration, calling for coexistence―the recognition of the interdependence of beings.In Art for Coexistence, art historian Christine Ross examines contemporary art’s response to migration, showing that art invites us to abandon our preconceptions about the current “crisis”―to unlearn them―and to see migration more critically, more disobediently. We (viewers in Europe and North America) must come to see migration in terms of coexistence: the interdependence of beings. The artworks explored by Ross reveal, contest, rethink, delink, and relink more reciprocally the interdependencies shaping migration today―connecting citizens-on-the-move from some of the poorest countries and acknowledged citizens of some of the wealthiest countries and democracies worldwide. These installations, videos, virtual reality works, webcasts, sculptures, graffiti, paintings, photographs, and a rescue boat, by artists including Banksy, Ai Weiwei, Alej

Demonstrating the range of linguistic and semiotic practices which are deployed in the construction of war memory, The Burden of Traumascapes investigates the discourses of remembering that are enculturated in the everyday lives of the people of Bosnia-Herzegovina. Maida Kosatica explores how the memory and narratives of the Bosnian War (1992-5) convey and renegotiate historical acts of violence in quite ordinary, banal ways and extend the war into the present day. Reintroducing the concept of 'traumascapes', this book demonstrates that semiotic landscapes are marked by traumatic legacies of violence in which the sense of trauma establishes its meaning through the discourses of remembering. In this context, this book argues that discourses of remembering, whether constructed in physical or virtual spaces, stem simultaneously from personal and collective needs to follow moral orders and responsibility, as well as from political, pedagogical and economic demands.

Overwhelming evidence exists that exposure to outdoor fine particulate matter (PM2.5) is associated with a range of short-term and chronic health impacts, including asthma exacerbation, acute and chronic bronchitis, heart attacks, increased susceptibility to respiratory infections, and premature death, with the burden of these health effects falling more heavily on underserved and marginalized communities. Although less studied to date, indoor exposure to PM2.5 is also gaining attention as a potential source of adverse health effects, particularly given that Americans spend 90 percent of their lives indoors and indoor PM2.5 levels can exceed outdoor levels. To better understand the sources of indoor PM2.5, the possible health effects of exposure to indoor PM2.5, and engineering approaches and interventions to reduce those exposure risks, the National Academies of Sciences, Engineering, and Medicine convened a virtual workshop, Indoor Exposure to Fine Particulate Matter and Practical Mi

Offering one of the first scholarly examinations of digital and distanced performance since the global shutdown of theaters in March 2020, Barbara Fuchs provides both a record of the changes and a framework for thinking through theater's transformation.Though born of necessity, recent productions offer a new world of practice, from multi-platform plays on Zoom, WhatsApp, and Instagram, to enhancement via filters and augmented reality, to urban distanced theater that enlivens streetscapes and building courtyards. Based largely outside the commercial theater, these productions transcend geographic and financial barriers to access new audiences, while offering a lifeline to artists. This study charts how virtual theater puts pressure on existing assumptions and definitions, transforming the conditions of both theater-making and viewership. How are participatory, site-specific, or devised theater altered under physical-distancing requirements? How do digital productions blur the line betwe
