Book excerpt: Examines how the US-Mexico border is seen through visual codes of surveillance When Donald Trump promised to “build a wall” on the U.S.-Mexico border, both supporters and opponents visualized a snaking barrier of concrete cleaving through nearly two thousand miles of arid desert. Though only 4 percent of the US population lives in proximity to the border, imagining what the wall would look like came easily to most Americans, in part because of how images of the border are reproduced and circulated for national audiences. Border Optics considers the US-Mexico border as one of the most visualized and imagined spaces in the US. As a place of continual crisis, permanent visibility, and territorial defense, the border is rendered as a layered visual space of policing—one that is seen from watchtowers, camera-mounted vehicles, helicopters, surveillance balloons, radar systems, unmanned aerial vehicles, and live streaming websites. It is also a space that is visualized across various forms and genres of media, from maps to geographical surveys, military strategic plans, illustrations, photographs, postcards, novels, film, and television, which combine fascination with the region with the visual codes of surveillance and survey. Border Optics elaborates on the expanded vision of the border as a consequence of the interface of militarism, technology, and media. Camilla Fojas describes how the perception of the viewing public is controlled through a booming security-industrial complex made up of entertainment media, local and federal police, prisons and detention centers, the aerospace industry, and all manner of security technology industries. The first study to examine visual codes of surveillance within an analysis of the history and culture of the border region, Border Optics is an innovative and groundbreaking examination of security cultures, race, gender, and colonialism.

Download or read book The Cybernetic Border written by Iván Chaar López and published by Duke University Press. This book was released on 2024-02-23 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Cybernetic Border, Iván Chaar López argues that the settler US nation requires the production and targeting of a racialized enemy that threatens the empire. The cybernetic border is organized through practices of data capture, storage, processing, circulation, and communication that police bodies and constitute the nation as a bounded, territorial space. Chaar López historicizes the US government’s use of border enforcement technologies on Mexicans, Arabs, and Muslims from the mid-twentieth century to the present, showing how data systems are presented as solutions to unauthorized border crossing. Contrary to enduring fantasies of the purported neutrality of drones, smart walls, artificial intelligence, and biometric technologies, the cybernetic border represents the consolidation of calculation and automation in the exercise of racialized violence. Chaar López draws on corporate, military, and government records, promotional documents and films, technical reports, news reporting, surveillance footage, and activist and artist practices. These materials reveal how logics of enmity are embedded into information infrastructures that shape border control and modern sovereignty.

Download or read book Border Rhetorics written by D. Robert DeChaine and published by University of Alabama Press. This book was released on 2012-08-30 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Undertakes a wide-ranging examination of the US-Mexico border as it functions in the rhetorical production of civic unity in the United States A “border” is a powerful and versatile concept, variously invoked as the delineation of geographical territories, as a judicial marker of citizenship, and as an ideological trope for defining inclusion and exclusion. It has implications for both the empowerment and subjugation of any given populace. Both real and imagined, the border separates a zone of physical and symbolic exchange whose geographical, political, economic, and cultural interactions bear profoundly on popular understandings and experiences of citizenship and identity. The border’s rhetorical significance is nowhere more apparent, nor its effects more concentrated, than on the frontier between the United States and Mexico. Often understood as an unruly boundary in dire need of containment from the ravages of criminals, illegal aliens, and other undesirable threats to the national body, this geopolitical locus exemplifies how normative constructions of “proper”; border relations reinforce definitions of US citizenship, which in turn can lead to anxiety, unrest, and violence centered around the struggle to define what it means to be a member of a national political community.

Download or read book Optics Manufacturing written by Christoph Gerhard and published by CRC Press. This book was released on 2017-12-14 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical components are essential key elements in modern engineering and everyday life. The education of skilled personnel and specialists in the fields of theoretical and practical optics manufacturing is of essential importance for next-generation technologies. Against this background, this book provides the basis for the education and advanced training of precision and ophthalmic optics technicians, craftsmen, and foremen, and it is an extensive reference work for students, academics, optical designers or shop managers, and production engineers. It not only covers particularly used and applied machines, working materials, testing procedures, and machining steps for classical optics manufacturing, but it also addresses the production and specification of optical glasses as well as unconventional production techniques and novel approaches. Optics Manufacturing: Components and Systems furthermore covers the basics of light propagation and provides an overview on optical materials and components; presents an introduction and explanation of the necessary considerations and procedures for the initial definition of manufacturing tolerances and the relevant industrial standards for optics manufacturing; and addresses the production of micro optics, the assembly of opto-mechanical setups and possible manufacturing errors, and the impact of the resulting inaccuracies. In order to allow fast and clear access to the most essential information, each chapter ends with a short summary of the most important aspects, including an explanation of relevant equations, symbols, and abbreviations. For further reading, extensive lists of references are also provided. Finally, exercises on the covered basic principles of optics, approaches, and techniques of optics manufacturing—including their corresponding detailed solutions—are found in the appendix.

Download or read book Unsettled Borders written by Felicity Amaya Schaeffer and published by Duke University Press. This book was released on 2022-05-02 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Unsettled Borders Felicity Amaya Schaeffer examines the ongoing settler colonial war over the US-Mexico border from the perspective of Apache, Tohono O’odham, and Maya who fight to protect their sacred land. Schaeffer traces the scientific and technological development of militarized border surveillance across time and space from Spanish colonial lookout points in Arizona and Mexico to the Indian wars, when the US cavalry hired Native scouts to track Apache fleeing into Mexico, to the occupation of the Tohono O’odham reservation and the recent launch of robotic bee swarms. Labeled “Optics Valley,” Arizona builds on a global history of violent dispossession and containment of Native peoples and migrants by branding itself as a profitable hub for surveillance. Schaeffer reverses the logic of borders by turning to Indigenous sacredsciences: ancestral land-based practices that are critical to reversing the ecological and social violence of surveillance, extraction, and occupation.
