American Exposures

"American Exposures sheds light on photographs, from Arthur Mole's propagandistic 'living photographs' of American icons and symbols to the exploration of contemporary subcultural communities by the Korean-born photographer and performance artist Nikki Lee, and asserts that the depiction of community is a central component to photography. Louis Kaplan deploys a number of critical concepts and theories developed by Jean-Luc Nancy in The Inoperative Community, as well as other philosophers, and applies them to the field of photography studies. With an original approach to photography from Edward Steichen's Family of Man exhibition to Pedro Meyer and the rise of the digital image, Kaplan points to a new way to think about the intimate relationship among photography, American life, and the artistic imagination." -- Back cover.

Textual Exposures: Photography in Twentieth Century Spanish American Narrative Fiction examines how twentieth-century Spanish American literature has registered photography's powers and limitations, and the creative ways in which writers of this region of the Americas have elaborated in fictional form the conventions and assumptions of this medium. While the book is essentially a study of literary criticism, it also aims to show how texts critically reflect upon the media environment in which they were created. The writings analyzed enter a dialogic relation with visual technologies such as the x-ray, cinema, illustrated journalism, and television. The study examines how these technologies, historically and aesthetically linked to the photographic medium, inform the works of some of the most important writers in Latin America. Methodologically, the close readings of the texts centre on the figure of ekphrasis (defined as the verbal representation of a visual representation). The book is concerned with the thematic, symbolic, structural and cultural imprints photography leaves in narrative texts. The author relies on an immanent approach, reading the selected texts according to their own specificities and making the relevant thematic and structural connections between them drawing from a variety of sources in the fields of literary criticism and theory and history of photography.

Chronic ethylbenzene exposures and attendant potential health risks for United States children and prospective parents were first evaluated under the United States Environmental Protection Agency’s Voluntary Children’s Chemical Evaluation Program. Using updated data and methods, a 2015 reevaluation observed declines in ethylbenzene releases and concentrations in ambient and indoor air. Both assessments identified inhalation as the dominant exposure route and smoking as the greatest contributor, with dietary intake much lower. Children’s exposure concentrations were similar to that of adults, but their intakes were higher. Neither breastfeeding nor toy mouthing was a significant source. This report updates the previous assessments, summarizing current ethylbenzene concentrations in air and foods, exposures during the use of household and consumer products, nationally representative biomonitoring data, including expanded demographic groups, and a new survey of worker exposures in styrene production facilities. General population ethylbenzene exposures appear to have declined for all age groups. The ethylbenzene/styrene chain of commerce contributes an estimated 0.1% to total air emissions and 7%-12% to dietary concentrations. Total estimated ethylbenzene intakes are consistent with biomonitoring data. Lactational transfer is not a significant exposure pathway for breastfed infants. Production workers’ exposure is well below occupational guidelines. Updated exposure estimates for each pathway suitable for potential health risk assessment are proposed.

In 1997, after more than a decade of research, the National Cancer Institute (NCI) released a report which provided their assessment of radiation exposures that Americans may have received from radioactive iodine released from the atomic bomb tests conducted in Nevada during the 1950s and early 1960s. This book provides an evaluation of the soundness of the methodology used by the NCI study to estimate: Past radiation doses. Possible health consequences of exposure to iodine-131. Implications for clinical practice. Possible public health strategies--such as systematic screening for thyroid cancer--to respond to the exposures. In addition, the book provides an evaluation of the NCI estimates of the number of thyroid cancers that might result from the nuclear testing program and provides guidance on approaches the U.S. government might use to communicate with the public about Iodine-131 exposures and health risks.

Coal remains one of the principal sources of energy for the United States, and the nation has been a world leader in coal production for more than 100 years. According to U.S. Energy Information Administration projections to 2050, coal is expected to be an important energy resource for the United States. Additionally, metallurgical coal used in steel production remains an important national commodity. However, coal production, like all other conventional mining activities, creates dust in the workplace. Respirable coal mine dust (RCMD) comprises the size fraction of airborne particles in underground mines that can be inhaled by miners and deposited in the distal airways and gas-exchange region of the lung. Occupational exposure to RCMD has long been associated with lung diseases common to the coal mining industry, including coal workers' pneumoconiosis, also known as "black lung disease." Monitoring and Sampling Approaches to Assess Underground Coal Mine Dust Exposures compares the monitoring technologies and sampling protocols currently used or required by the United States, and in similarly industrialized countries for the control of RCMD exposure in underground coal mines. This report assesses the effects of rock dust mixtures and their application on RCMD measurements, and the efficacy of current monitoring technologies and sampling approaches. It also offers science-based conclusions regarding optimal monitoring and sampling strategies to aid mine operators' decision making related to reducing RCMD exposure to miners in underground coal mines.
