Techniques Of The Observer

Jonathan Crary's Techniques of the Observer provides a dramatically new perspective on the visual culture of the nineteenth century, reassessing problems of both visual modernism and social modernity. This analysis of the historical formation of the observer is a compelling account of the prehistory of the society of the spectacle. In Techniques of the Observer Jonathan Crary provides a dramatically new perspective on the visual culture of the nineteenth century, reassessing problems of both visual modernism and social modernity. Inverting conventional approaches, Crary considers the problem of visuality not through the study of art works and images, but by analyzing the historical construction of the observer. He insists that the problems of vision are inseparable from the operation of social power and examines how, beginning in the 1820s, the observer became the site of new discourses and practices that situated vision within the body as a physiological event. Alongside the sudden appearance of physiological optics, Crary points out, theories and models of "subjective vision" were developed that gave the observer a new autonomy and productivity while simultaneously allowing new forms of control and standardization of vision. Crary examines a range of diverse work in philosophy, in the empirical sciences, and in the elements of an emerging mass visual culture. He discusses at length the significance of optical apparatuses such as the stereoscope and of precinematic devices, detailing how they were the product of new physiological knowledge. He also shows how these forms of mass culture, usually labeled as "realist," were in fact based on abstract models of vision, and he suggests that mimetic or perspectival notions of vision and representation were initially abandoned in the first half of the nineteenth century within a variety of powerful institutions and discourses, well before the modernist painting of the 1870s and 1880s.

Suspensions of Perception decisively relocates the problem of aesthetic contemplation within a broader collective encounter with the unstable nature of perception—in psychology, philosophy, neurology, early cinema, and photography. Suspensions of Perception is a major historical study of human attention and its volatile role in modern Western culture. It argues that the ways in which we intently look at or listen to anything result from crucial changes in the nature of perception that can be traced back to the second half of the nineteenth century. Focusing on the period from about 1880 to 1905, Jonathan Crary examines the connections between the modernization of subjectivity and the dramatic expansion and industrialization of visual/auditory culture. At the core of his project is the paradoxical nature of modern attention, which was both a fundamental condition of individual freedom, creativity, and experience and a central element in the efficient functioning of economic and disciplinary institutions as well as the emerging spaces of mass consumption and spectacle. Crary approaches these issues through multiple analyses of single works by three key modernist painters—Manet, Seurat, and Cezanne—who each engaged in a singular confrontation with the disruptions, vacancies, and rifts within a perceptual field. Each in his own way discovered that sustained attentiveness, rather than fixing or securing the world, led to perceptual disintegration and loss of presence, and each used this discovery as the basis for a reinvention of representational practices. Suspensions of Perception decisively relocates the problem of aesthetic contemplation within a broader collective encounter with the unstable nature of perception—in psychology, philosophy, neurology, early cinema, and photography. In doing so, it provides a historical framework for understanding the current social crisis of attention amid the accelerating metamorphoses of our contemporary technological culture.

Gives an accessible overview of R programming for medical imaging and the methods of observer performance testing. Explains the fundamental statistical concepts. Reinforces learning using worked problems and R software code, in addition to examples that utilize standalone ROC software. Starts with basic ROC analysis and builds to extensions of ROC methods for solving more complex but clinically realistic tasks. Emphasizes psychophysical models of observer performance (e.g., binormal model, contaminated binormal model, proper ROC model), and demonstrates how they can give better results than from purely statistical approaches.

Due to its abilities to compensate disturbances and uncertainties, disturbance observer based control (DOBC) is regarded as one of the most promising approaches for disturbance-attenuation. One of the first books on DOBC, Disturbance Observer Based Control: Methods and Applications presents novel theory results as well as best practices for applica

Long considered "the noblest of the senses," vision has increasingly come under critical scrutiny by a wide range of thinkers who question its dominance in Western culture. These critics of vision, especially prominent in twentieth-century France, have challenged its allegedly superior capacity to provide access to the world. They have also criticized its supposed complicity with political and social oppression through the promulgation of spectacle and surveillance. Martin Jay turns to this discourse surrounding vision and explores its often contradictory implications in the work of such influential figures as Jean-Paul Sartre, Maurice Merleau-Ponty, Michel Foucault, Jacques Lacan, Louis Althusser, Guy Debord, Luce Irigaray, Emmanuel Levinas, and Jacques Derrida. Jay begins with a discussion of the theory of vision from Plato to Descartes, then considers its role in the French Enlightenment before turning to its status in the culture of modernity. From consideration of French Impressionism to analysis of Georges Bataille and the Surrealists, Roland Barthes's writings on photography, and the film theory of Christian Metz, Jay provides lucid and fair-minded accounts of thinkers and ideas widely known for their difficulty. His book examines the myriad links between the interrogation of vision and the pervasive antihumanist, antimodernist, and counter-enlightenment tenor of much recent French thought. Refusing, however, to defend the dominant visual order, he calls instead for a plurality of "scopic regimes." Certain to generate controversy and discussion throughout the humanities and social sciences, Downcast Eyes will consolidate Jay's reputation as one of today's premier cultural and intellectual historians.

Participant observation is the foundation of ethnographic research design and supports and complements other types of qualitative and quantitative data collection. Qualitative research in such diverse areas as anthropology, sociology, education, medicine draws on the insights gained through the use of participant observation. The authors have written a guide to the collection of systematic data in naturalistic settings - communities in many different cultures - to achieve an understanding of the most fundamental processes and patterns of social life. This book serves as a basic primer for the beginning researcher and as a useful reference and guide for experienced researchers in many fields who wish to reexamine their own skills and abilities in light of best practices of participant observation. This new edition includes discussions of participant observation in nontypical settings, such as the Internet, participant observation in applied research, and ethics of participant observation. It also explores in greater depth the use of computer-assisted analysis of textual data in issues of sampling and in linking method with theory.
