Virtual Control and Disciplining on the Internet: Electronic Governmentality in the New Wired World     

Michael D. Mehta Eric Darier 《The Information Society》1998,14(2):107-116

Current interest in the electronic highway is the latest expression of a technotopia that is about to resolutely tilt Western contemporary society into postmodernity, or at least into virtual modernity. The enthusiasm for the electronic highway is already having numerous 'power effects' (Burchell et al., 1991). One of these effects is to radically intensify modern forms of power in a new regime we call electronic governmentality. This article examines these effects by drawing on examples from the Internet, and demonstrates how this communication and information infrastructure challenges some of our most tightly held beliefs about progress, technology, and power.  相似文献   

Effects of pretraining on acquisition of novel configural discriminations in human predictive learning     

Rick Mehta  Emily Russell 《Learning & behavior》2009,37(4):311-324

In two experiments, participants acquired one of two target configural discriminations (a biconditional or negative patterning discrimination) in a predictive learning task. In Experiment 1, participants were pretrained with either a configural or an elemental discrimination; in Experiment 2, they were pretrained with a configural discrimination, an elemental discrimination, or a control discrimination that was not expected to bias them toward elemental or configural processing. In both experiments, acquisition of the target configural discriminations was faster after configural pretraining than after elemental pretraining. In addition, the negative patterning discrimination was acquired faster than the biconditional discrimination. Finally, the results of Experiment 2 were more consistent with the notion that elemental pretraining hindered acquisition of the target discriminations than with the notion that configural pretraining enhanced their acquisition. Implications of these findings are discussed.  相似文献   

Levels of cerebrospinal fluid acetylcholinesterase in tuberculous and pyogenic meningitis in children

Total acetylcholinesterase (AChE) activity was estimated in cerebrospinal fluid (CSF) using colorimetric method in 64 cases with tuberculous meningitis, (TBM) (n=64), pyogenic meningitis (PM) (n=60) and in controls (n=39) of paediatric age group. Mean CSF—AChE values of both TBM and PM were significantly higher when compared with controls (p<0.001) but no significant change between TBM and PM was observed (p<0.01). It is suggested that inflammation of meninges due to the infection may attribute to a change in the function of blood brain barrier (BBB) causing higher CSF—AChE values in these diseases.  相似文献
