In the formation of an image each small volume element of the object is correlated to an areal element in the image. The structure or detail of the object is represented by changes in intensity from element to element, and this variation of intensity (contrast) is determined by the interaction of the electrons with the specimen, and by the optical processing of the information-carrying electrons. Both conventional and scanning transmission electron microscopes form images which may be considered in this way, but the mechanism of image construction is very different in the two cases. Although the electron-object interaction is the same, the optical treatment differs.

For the past several years, experimental studies have been undertaken at the Mayo Clinic to evaluate the feasibility of utilizing electronic data processing to handle medical information, especially the medical information which makes up a medical record. We have experimented with automated techniques for collecting and storing medical-history data, specifically with techniques for computer generation and processing of health questionnaires, for computer-controlled administration of health questionnaires, and for computer-controlled entry and retrieval of medical-history data directly by physicians in ordinary English language by use of a video-screen and light-pen computer terminal.The questionnaire studies are concerned with ways of entering into computer storage medical-history data obtained from patients without physician involvement; the video-screen studies are concerned with entry into computer storage of medical-history data obtained by physicians in their interview with the patient. The paper describes our experiences in these studies.

By looking at Jean Rhys’s ‘Left Bank’ fiction (Quartet, After Leaving Mr Mackenzie, Good Morning, Midnight, ‘Illusion’, ‘Mannequin’), this chapter investigates how new operational procedures such as Fordism and Taylorism, which were introduced into the French couture industry at the beginning of the twentieth century, affected constructions of modern femininity. Increasingly standardized images of feminine types were produced by Paris couturiers while the new look of the Flapper seemingly advertised women’s expanding social, political and professional mobility. Rhys, this chapter argues, noted fashion’s ability to provide resources for creative image construction but she simultaneously expressed criticism of its tendency to standardize female costumes and behaviour. Ultimately, Rhys demonstrates in her fiction that the radically modern couture of the early twentieth century was by no means the maker of social change and women’s political modernity. To offset the increased standardization of female images that she witnessed around her, Rhys created heroines and texts that relied on an overt display on difference.
