Red Light Dark Room

In China today, sex work cannot be untangled from the phenomenon of rural-urban migration, the entertainment industry, and state power. In Red Lights, Tiantian Zheng highlights the urban karaoke bar as the locus at which these three factors intersect and provides a rich account of the lives of karaoke hostesses--a career whose name disguises the sex work and minimizes the surprising influence these women often have as power brokers.

The first comprehensive encyclopedia of world photograph up to the beginning of the twentieth century. It sets out to be the standard, definitive reference work on the subject for years to come.

The object of this work has been to present, in a clear, logical, and if possible attractive form, the fundamental facts connected with our perception of colour, so far as they are at present known, or concern the general or artistic reader. For the explanation of these facts, the theory of Thomas Young, as modified and set forth by Helmholtz and Maxwell, has been consistently adhered to. The whole class of musical theories, as well as that of Field, have been discarded, for reasons that are set forth in the text. Turning now from the more purely scientific to the aesthetic side of the subject, I will add that it has been my endeavour also, to present in a simple and comprehensible manner the underlying facts upon which the artistic use of colour necessarily depends. The possession of these facts will not enable people to become artists; but it may to some extent prevent ordinary persons, critics, and even painters, from talking and writing about colour in a loose, inaccurate, and not always rational manner. More than this is true: a real knowledge of elementary facts often serves to warn students of the presence of difficulties that are almost insurmountable, or, when they are already in trouble, points out to them its probable nature; in short, a certain amount of rudimentary information tends to save useless labour. Those persons, therefore, who are really interested in this subject are urged to repeat for themselves the various experiments indicated in the text. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing many of these classic works in affordable, high quality, modern editions, using the original text and artwork.

Roy Sorensen here defends the causal theory of perception by treating absences as causes. He draws heavily on common sense and psychology to vindicate the assumption that we directly perceive absences.

A thorough review that covers fundamentals, assessment, clinical services, training and instructional services, and future directions. The author establishes a framework for understanding the impact of low vision on functioning, learning, and psychosocial status. Special sections contain chapters, reports, technical materials, curriculum guides, resources, and questionnaires by experts from 21 areas.

Photobiology - the science of light and life - begins with basic principles and the physics of light and continues with general photobiological research methods, such as generation of light, measurement of light, and action spectroscopy. In an interdisciplinary way, it then treats how organisms tune their pigments and structures to the wavelength components of light, and how light is registered by organisms. Then follow various examples of photobiological phenomena: the design of the compound eye in relation to the properties of light, phototoxicity, photobiology of the human skin and of vitamin D, photomorphogenesis, photoperiodism, the setting of the biological clock by light, and bioluminescence. A final chapter is devoted to teaching experiments and demonstrations in photobiology. This book encompasses topics from a diverse array of traditional disciplines: physics, biochemistry, medicine, zoology, botany, microbiology, etc., and makes different aspects of photobiology accessible to experts in all these areas as well as to the novice.
