Gundula Kreuzer challenges common assumptions about the ‘screenification’ of contemporary opera productions by reconsidering historical screening techniques within staged opera. Beginning with the Baroque picture-frame stage, she highlights how a desire for visual illusion on stage came into conflict with the increasingly complicated array of equipment, scenery, and props required to produce such elaborate scenes. Retracing strategies tested out at Wagner’s Festspielhaus at Bayreuth, she argues that the theatre’s curtain line came to imply an invisible screen with the capacity to organize the various media on the deep stage into a unified whole, a perception fostered by the visual and acoustic environment of the auditorium. Rather than a part of the telos of modernist painting, she highlights this flattened planar format as the outcome of technical and aesthetic conflict, whose legacy proves highly relevant to contemporary experiments with operatic staging.

Determination of the microstructure and microchemistry of small features often provides the insight needed for the understanding of processes in real materials. In many cases, it is not adequate to use microscopy alone. Microdiffraction and microspectroscopic information such as EELS, X-ray microprobe analysis and Auger spectroscopy can all contribute vital parts of the picture. For a number of reasons, dedicated STEM offers considerable promise as a quantitative instrument. In this paper, we review progress towards effective quantitative use of STEM with illustrations drawn from studies of high Tc superconductors, compound semiconductors and metallization of H-terminated silicon.Intrinsically, STEM is a quantitative instrument. Images are acquired directly by detectors in serial mode which is particularly convenient for digital image acquisition, control and display. The VG HB501A at Cornell has been installed in a particularly stable electromagnetic, vibration and acoustic environment. Care has been paid to achieving UHV conditions (i.e., 10-10 Torr). Finally, it has been interfaced with a VAX 3200 work station by Kirkland. This permits, for example, the acquisition of bright field (or energy loss) images and dark field images simultaneously as quantitative arrays in perfect registration.

The Impact

Objectives This study investigates the hypothesis that hearing aid amplification reduces effort within conversation for both hearing aid wearers and their communication partners. Levels of effort, in the form of speech production modifications, required to maintain successful spoken communication in a range of acoustic environments are compared to earlier reported results measured in unaided conversation conditions. Design Fifteen young adult normal-hearing participants and 15 older adult hearing-impaired participants were tested in pairs. Each pair consisted of one young normal-hearing participant and one older hearing-impaired participant. Hearing-impaired participants received directional hearing aid amplification, according to their audiogram, via a master hearing aid with gain provided according to the NAL-NL2 fitting formula. Pairs of participants were required to take part in naturalistic conversations through the use of a referential communication task. Each pair took part in five conversations, each of 5-min duration. During each conversation, participants were exposed to one of five different realistic acoustic environments presented through highly open headphones. The ordering of acoustic environments across experimental blocks was pseudorandomized. Resulting recordings of conversational speech were analyzed to determine the magnitude of speech modifications, in terms of vocal level and spectrum, produced by normal-hearing talkers as a function of both acoustic environment and the degree of high-frequency average hearing impairment of their conversation partner. Results The magnitude of spectral modifications of speech produced by normal-hearing talkers during conversations with aided hearing-impaired interlocutors was smaller than the speech modifications observed during conversations between the same pairs of participants in the absence of hearing aid amplification. Conclusions The provision of hearing aid amplification reduces the effort required to maintain communication in adverse conditions. This reduction in effort provides benefit to hearing-impaired individuals and also to the conversation partners of hearing-impaired individuals. By considering the impact of amplification on both sides of dyadic conversations, this approach contributes to an increased understanding of the likely impact of hearing impairment on everyday communication.

This article addresses the distinctive spiritual qualities of aerial movement. Taking as a point of departure the feature lm Maria, Mãe do Filho de Deus (2003) played by famous Brazilian Padre Marcelo Rossi, it argues for an engagement with cinematic images in terms of aerial dynamic imagination. It will be shown that the “inspired breath” of Padre Marcelo organizes the universe and affects the constitution of subjects and space in the lm according to the Scriptures. The same aerial dynamic applies to his other contexts of performance such as Byzantine praying techniques and their relation to space. Subsequently, the article explores underlying analogies between electronic technology, acoustic environment, and pneumatic spirituality within common practices of embodied experience.

History Of

The study is an investigation of the origins of psychophysics and experimentalpsychology. According to historians of psychology. FrancisBacon had the most crucial influence in the history of the experimentalmethod, because he emphasized the importance of induction, skepticism,quantification, and observation. The present study, however,attempts to show that Ibn al-Haytham laid the foundations of the aboveaspects of the experimental method. Furthermore, a number of historiansof psychology believe that Fechner was the founder of psychophysicswith his application “Filements of Psychophysics” in 1860.This study shows that in the eleventh century, Ibn al-Haytham made anoriginal contribution to the study of vision, wherein his psychophysicsborrowed its structure from physics and its spirit from psychology.Several aspects of visual perception were investigated by him, includingsensation (which occupies a central place in psychophysics), variationsin sensitivity, perception of colors. sensation of touch, perceptionof darkness, the psychological explanation of moon illusion, and binocularvision. This study presents five experiments by Ibn al-Haythamregarding the errors of vision, which is called in contemporary psychology“visual illusion.” These experiments have been applied andverified in Bahrain from both the physical and psychological perspectives.Finally, the study concludes that Ibn al-Haytham deserves the title“founder” of psychophysics as wellp the “founder” of experimentalpsychology. In this respect. Kitab ul-Manazir by Ibn al-Haytham.which appeared in the fmt half of the eleventh century, and not the“Elements of Psychophysics” by Fechner. which was published in thenineteenth century, marks the official “founding” of psychology,because it provides not only new concepts and theories but new methodsof measurement in psychology.
