Sommario/riassunto |
|
"This is the first book to address the fundamental operation principles, device characteristics, and potential applications of various types of adaptive lenses. Setting out from basic material properties to device structures and performance, this volume covers solid lens, membrane lens, electro-wetting lens, dielectric lens, mechanical-wetting lens, and liquid crystal lenses. Potential applications of these adaptive lenses are also investigated, including image processing and zooming, optical communications, and biomedical imaging. This is an important reference for optical engineers, research scientists, graduate students and undergraduate seniors"-- |

Sommario/riassunto |
|
She’s skinny, white, and blond. She’s Barbie—an icon of femininity to generations of American girls. She’s also multiethnic and straight—or so says Mattel, Barbie’s manufacturer. But, as Barbie’s Queer Accessories demonstrates, many girls do things with Barbie never seen in any commercial. Erica Rand looks at the corporate marketing strategies used to create Barbie’s versatile (She’s a rapper! She’s an astronaut! She’s a bride!) but nonetheless premolded and still predominantly white image. Rand weighs the values Mattel seeks to embody in Barbie—evident, for example, in her improbably thin waist and her heterosexual partner—against the naked, dyked out, transgendered, and trashed versions favored by many juvenile owners and adult collectors of the doll.Rand begins by focusing on the production and marketing of Barbie, starting in 1959, including Mattel’s numerous tie-ins and spin-offs. These variations, which include the |

much-promoted multiethnic Barbies and the controversial Earring Magic Ken, helped make the doll one of the most profitable toys on the market. In lively chapters based on extensive interviews, the author discusses adult testimony from both Barbie "survivors" and enthusiasts and explores how memories of the doll fit into women’s lives. Finally, Rand looks at cultural reappropriations of Barbie by artists, collectors, and especially lesbians and gay men, and considers resistance to Barbie as a form of social and political activism.Illustrated with photographs of various interpretations and alterations of Barbie, this book encompasses both Barbie glorification and abjection as it testifies to the irrefutably compelling qualities of this bestselling toy. Anyone who has played with Barbie—or, more importantly, thought or worried about playing with Barbie—will find this book fascinating. |
