Drug-use surveillance systems appear in this paper as symptomatic “technologies of suspicion” that constitute a set of empirical modes for producing and interpreting “data” or test results in ways that conflate prediction with prescription, acting as technological forms of supervision, monitoring, supposed deterrence, and ultimately control. Technologies of suspicion are predicated upon a framework of trust; they are deployed within a “system of takings-for-granted” that presupposes trust and thus makes distrust possible. Drug-testing provides an excellent example of the institutionalization of distrust through the deployment of technologies of suspicion not only within institutions but beyond their real and virtual walls. The paper considers the also considers the decentralization and deinstitutionalization of distrust, the capillary dispersion of suspicion throughout the carceral society, and the role of distrust in underwriting the development of certain kinds of knowledge systems and technologies, forms of social and cognitive order, and the functional dispersion of police practices to individuals such as parents, teachers, and peers. Studying why bio-surveillance modalities should diffuse despite their unreliability and their contribution to a generalized climate of suspicion enables the characterization of certain features of the post-sovereign subject in a post-disciplinary regime.

Twin Bounded SVM (TB-SVM) is an improvement of the Twin SVM method and has advantages in classification problems compared to standard SVM. In this research, linear TB-SVM and nonlinear TB-SVM methods will be applied to detect drug use based on 23 symptoms experienced. The training and testing data is divided into three partition data schemes (60/40 scheme, 70/30 scheme and 80/20 scheme) in order to determine the best level of accuracy that can be obtained. The test results show that the nonlinear TB-SVM with the RBF kernel has a better accuracy rate than the linear TB-SVM, that is 80% at 60/40 scheme, 90% at 70/30 scheme, and 95% at 80/20 scheme.

Abstract PurposeTo assess structural (optical coherence tomography, fundus autofluorescence) and functional (contrast sensitivity and visual field) test results used for detecting early retinal changes in patients who were using oral hydroxychloroquine.METHODSPatients who were taking oral hydroxychloroquine for at least one year were divided into two groups in accordance with the duration of drug use. Group 1 and 2 comprised patients with drug use exceeding 5 years and 1–5 years, respectively. Besides, drug-free control group was composed. Upon full ophthalmic examination, the mean retinal nerve layer thickness (RNFL), central macular thickness (CMT), ganglion cell-inner plexiform layer thickness (GC-IPL), static 10 − 2 visual field, fundus autofluorescence (FAF) imaging, and contrast sensitivity tests were performed and statistically compared between groups.RESULTSRNFL thickness was found to be statistically significantly lower in the median and temporal quadrant than in the control group. No significant difference was found between the groups in the other quadrants. The GC-IPL sectoral and mean thickness were found to be statistically lower in all quadrants as compared to the control group in the patient groups. CMT was also found to be similar in all three groups. There was no significant difference between the groups in visual field parameters. While macular FAF images were significantly higher in the drug users than in the control group, no significant difference was found between the three groups in foveal FAF images. Contrast sensitivity measurements were significantly lower in the patient groups than in the control group at all spatial frequencies except 6 and 18 cycles / degree.CONCLUSIONSThe combined use of structural and functional tests in patients using hydroxychloroquine provides useful information in detecting early retinal changes.
