'Babylonian flats' in victorian and edwardian London
The first half of this paper examines the controversy associated with the building of Queen Anne's Mansions, London's first high-rise flats, erected between 1873 and 1890, and a catalyst for the introduction of height restrictions in the London Building Acts of 1890 and 1894. Subsequent sections consider the building's place in the imagination of Londoners, the marketing of the mansions, which emphasised their height and novelty, and the characteristics of residents, especially as recorded in the 1901 census. The paper concludes by positioning Queen Anne's Mansions in wider debates about living in flats and the acceptability of high-rise buildings in nineteenth-and early twentieth-century London. © The London Journal Trust 2008

Using authentic 3D product visualisation for an electrical online retailer
This study investigates the effects of authentic three dimensional (3D) product visualisation versus 3D telepresence on consumers’ virtual experience. A hypothetical electrical retailer Web site presents a variety of laptops using 3D product visualisations for the within-subjects laboratory experiments. The first experiment uses two-way repeated measures ANOVA to determine the effects of the antecedents on 3D authenticity. In a second experiment, a one-way ANOVA compares telepresence and authenticity scores. This research uses a U.K. sample to investigate the effects of control and animated colours on 3D authenticity and the effects of 3D authenticity on experiential and instrumental values. The results reveal significant differences between telepresence and authenticity constructs. Authenticity is more significant in simulating an online retailer’s products, and control and animated colours represent the main antecedents of authenticity. Moreover, experiential and instrumental values represent the main consequences of 3D authenticity

Contextual specificity in perception and action
The visually guided control of helicopter flight is a human achievement, and, thus, understanding this skill is, in part, a psychological problem. The abilities of skilled pilots are impressive, and yet it is of concern that pilots' performance is less than ideal: they suffer from workload constraints, make occasional errors, and are subject to such debilities as simulator sickness. Remedying such deficiencies is both an engineering and a psychological problem. When studying the psychological aspects of this problem, it is desirable to simplify the problem as much as possible, and thereby, sidestep as many intractable psychological issues as possible. Simply stated, we do not want to have to resolve such polemics as the mind-body problem in order to contribute to the design of more effective helicopter systems. On the other hand, the study of human behavior is a psychological endeavor and certain problems cannot be evaded. Four related issues that are of psychological significance in understanding the visually guided control of helicopter flight are discussed. First, a selected discussion of the nature of descriptive levels in analyzing human perception and performance is presented. It is argued that the appropriate level of description for perception is kinematical, and for performance, it is procedural. Second, it is argued that investigations into pilot performance cannot ignore the nature of pilots' phenomenal experience. The conscious control of actions is not based upon environmental states of affairs, nor upon the optical information that specifies them. Actions are coupled to perceptions. Third, the acquisition of skilled actions in the context of inherent misperceptions is discussed. Such skills may be error prone in some situations, but not in others. Finally, I discuss the contextual relativity of human errors. Each of these four issues relates to a common theme: the control of action is mediated by phenomenal experience, the veracity of which is context specific

Suspension cell culture in microgravity and development of a space bioreactor
NASA has methodically developed unique suspension type cell and recovery apparatus culture systems for bioprocess technology experiments and production of biological products in microgravity. The first space bioreactor has been designed for microprocessor control, no gaseous headspace, circulation and resupply of culture medium, and slow mixing in very low shear regimes. Various ground based bioreactors are being used to test reactor vessel design, on-line sensors, effects of shear, nutrient supply, and waste removal from continuous culture of human cells attached to microcarriers. The small (500 ml) bioreactor is being constructed for flight experiments in the Shuttle middeck to verify systems operation under microgravity conditions and to measure the efficiencies of mass transport, gas transfer, oxygen consumption, and control of low shear stress on cells
