Abstract

This article deals with the concept of market information. In particular, it argues that references to the so-called conduit metaphor, which represents markets as a series of information flows, hide the localized, historically contingent and materially mediated practices of the economy. Following the tradition of the performative theory of social institutions, this article argues that the specific meaning of ‘market information’ and its concrete manifestations (e.g. prices) depend on the sociotechnical character of the calculative practices through which market participants orient their economic actions. The point is illustrated through a historical reconstruction of the introduction of price and quote dissemination technologies in the London Stock Exchange between 1955 and 1990. By highlighting the historical and technological contingency of prices, the case of the London Stock Exchange shows that it is impossible to provide a universally and temporally invariant definition of market information.  相似文献

This essay investigates the centrality of the U.S. Military in the process of automating the labor of surveillance. The creation of Semi-Automatic Ground Environment (SAGE), an anti-nuclear defense system developed in the 1950s, marked the computerization of the perceptual, mnemonic, and epistemological labor that is necessary for surveillance and is emblematic of screening technologies. The essay situates SAGE in a long history of military surveillance that depended upon media technologies. Building upon the work of Michel Foucault and Freidrich Kittler, it is argued that media are essential for understanding how surveillance is problematized for security.  相似文献

Political and social stability in advanced capitalist societies is threatened both by the impossibility of achieving full employment owing to automation and the transformation of family life and gender relationships. This article explores explanations of these shifts in Jeremy Rifkin's and Ray Pahl's work. It explores alternative models of employment in which formal work is shared and third-sector work is expanded, underwritten by a cultural shift in which work, success and consumption are traded for free time, balance and self-development.  相似文献

Abstract: Microscopic analysis for the identification of spermatozoa is commonly performed during the forensic examination of sexual assault evidence. Two widely utilized methods for the confirmation of the presence of spermatozoa are visualization of the cells via phase‐contrast microscopy with wet mounted samples and bright field microscopy with histologically stained samples. The KPICS SpermFinder? by NicheVision Forensics, LLC accelerates this time‐consuming process via an automated microscope with an algorithm designed to locate spermatozoa on a Christmas tree histologically stained microscope slide. Upon a qualified scientist’s review of the generated data, the KPICS SpermFinder? was able to locate spermatozoa, typically finding on average 106.28% ± 115.37% more spermatozoa than with manual examinations. The KPICS SpermFinder? provided the location of identified cells with reproducible results.  相似文献

Abstract: Automated platforms used for forensic casework sample DNA extraction need to be versatile to accommodate a wide variety of sample types, thus protocols frequently need modification. In this study, DNA IQ? methods previously developed for the Biomek® 2000 Automation Workstation were adapted for the Teleshake Unit using normal volumes and all deepwell extraction, and a large volume DNA IQ? method developed. DNA purification without detectable contamination of adjacent reagent blanks is reported in the extraction of tissue samples containing several micrograms of DNA. Sensitivity and contamination studies demonstrated similar performance with the manual organic extraction method for bloodstain dilution samples. Mock casework samples demonstrated the effectiveness of the Teleshake and Teleshake large volume methods. Because of the performance and increased versatility of the DNA IQ? extraction with these modifications, the Teleshake Unit has been implemented in both normal and large volume automated DNA extractions at the Virginia Department of Forensic Science.  相似文献

Sexual assault evidence samples require the use of a specific process known as a differential digestion to separate sperm from nonsperm cells prior to DNA extraction. An automated differential digestion process was developed using a selective degradation technique, which uses DNase I to digest the remaining nonsperm DNA in the sperm fraction. The use of DNase on pristine samples, as well as aged and degraded samples, was assessed to ensure that the quantity and quality of the sperm DNA were not compromised or adversely affected. Samples processed using the selective degradation technique yielded comparable DNA yield and DNA typing data to the conventional differential digestion process. The automated process utilized 96‐well plates for high throughput and incorporated microscope slide preparations for confirmation of sperm. It reduced processing time by about sixfold and was paramount in the elimination of the Oakland Police Department Criminalistics Laboratory's sexual assault kit backlog.  相似文献

A new pairwise osteometric pair‐matching approach based on the Z‐transform method is presented. In contrast to previous methods that perform a global t‐test on the summed skeletal element pair measurement distances, this approach performs t‐tests on each individual distance, facilitating the capture of measurement‐specific variation. This new approach is compared to published pairwise sorting methods using a standard reference dataset of postcranial remains maintained by the Defense POW/MIA Accounting Agency. Receiver operating characteristic curve analysis indicates significantly improved performance for the clavicle and radius over all previous methods (p < 0.01). The z‐transform method weighted by the effect size outperformed the t‐test (Byrd and Adams) and the mean t‐test (Lynch) for all elements (p < 0.01). The method performed better than the absolute value t‐test (Lynch) for five elements (p < 0.01) and performed at least as well for the remainder. To facilitate usability all methods are available at: https://github.com/spawaskar-cora/z-transform-method .  相似文献
