In 2017, Russian President Vladimir Putin declared that whichever country becomes the leader in artificial intelligence (AI) “will become the ruler of the world.” Yet Russia lags competitors like China and the United States substantially in AI capabilities. What is Russia's strategy for boosting development of AI technologies, and what role do groups within the Russian elite play in shaping this strategy? Russia's AI development strategy is unique in that it is led not by the government, nor by the private sector, but by state-owned firms. The government's distrust of Russia's largest tech firm, Yandex, has sidelined the company from national AI planning. Meanwhile, Russia's defense conglomerate Rostec publicly appears to focus less on artificial intelligence than on other high-tech priorities. As a result, Russia's AI development has been left to a state-owned bank, Sberbank, which has taken the lead in devising plans for government-backed investment in AI. 相似文献

Prior studies have documented linkages between mental disorder and both offending and victimization. However, few studies
have examined the violent offending–violent victimization overlap among mentally disordered individuals and none have examined
the factors that are jointly related to their covariation. Here, we assess this overlap during the first ten weeks following
hospital discharge among a large sample of psychiatric patients from three large cities. Findings indicate that: (1) violent
offending and violent victimization show substantial covariation; (2) although each of the two outcomes were predicted by
a few unique risk factors, several risk factors were similarly predictive of both outcomes; and (3) even after adjusting for
demographic, clinical, and social risk factors, the correlation between violent offending and violent victimization remained
robust. Implications for theory, research, and policy are highlighted. 相似文献

Despite numerous instrumental achievements, canines are still considered the most effective field method for explosive detection. However, due to strict explosive regulations and safety requirements, it can be a challenge for agencies with "bomb dogs" to train using neat explosive materials. This establishes a need for non-explosive canine training aids with the same volatile component profiles as the explosives that they represent. In order to compare mimic materials to their explosive counterparts, a technique must be established that not only allows for identification of volatile compounds but also can monitor changes in the headspace profile over time with respect to time and temperature. The Automated Training Aid Simulation using SPME (or ATASS) was developed for that purpose. As described, ATASS was used to observe changes in the volatile profile of three explosives (Composition C-4, 2,4-dinitrotoluene (DNT), and triacetone triperoxide (TATP)) and respective prototype training materials (0.1% by mass C-4, 1% by mass 2,4-DNT, and 1% by mass TATP). Samples were prepared in vials and metal tins within a gallon (≈ 3785 mL) paint can to simulate common field techniques for canine training. Monitoring these materials in real time provides a better understanding of the major volatile components present and how the relative abundances of these components can change over time. The results presented indicate that ATASS successfully allows for a sufficient comparison between explosive and non-explosive training materials. 相似文献

A considerable number of individuals show resistance to reform, whereas others, although similarly affected, do not react
in a resistant way at all. Based on research showing that people differ concerning how sensitive they are toward being a victim
of injustice (victim justice sensitivity), we argued that people high in victim justice sensitivity perceive a reform more
as an illegitimate limitation to their freedom resulting in more reactance. Consequently, people high in victim justice sensitivity
should show more resistance to reform. We conducted three studies to test these assumptions. Our studies revealed that physicians
(healthcare reform, Study 1) and students (introduction of tuition fees, Studies 2 and 3) with higher victim justice sensitivity
experienced more reactance and thus showed more resistance to reform. The implications of these results for the implementation
of political reforms are discussed. 相似文献

Should counselors with interpersonal trauma histories work with similarly traumatized clients? How does the work affect them? Current research is inconsistent. This study examines 101 sexual assault and domestic violence counselors' recalled motivations for trauma work, their reported subjective personal changes, and their secondary and vicarious trauma symptoms and burnout. Counselors motivated by interpersonal trauma report both more symptoms and positive changes (including dealing with their own trauma). Those seeking personal meaning report becoming more hypervigilant and self-isolating. Those saying they learned from clients rate symptoms lower, suggesting stress inoculation. Supervisors of trauma counselors should facilitate learning from clients separately from processing the counselor's trauma. 相似文献

We appreciate Boone’s (2011, this issue) critique of Rogers, Bender, and Johnson’s (2011, this issue) analysis of the Malingered Neurocognitive Dysfunction (MND) criteria. She raised good points and appeared in general agreement regarding several crucial limitations of the MND model. However, Boone remained mostly silent on several issues including the compelling results from our methodological review of MND studies and Criteria A through D. When provided, her comments tended to be very selective and were often presented with little or no empirical support. This contrasting pattern of strong statements and weak evidence appears to unintentionally parallel the MND model, which was documented in our original analysis. As a result of her criticism, however, we clarified our point regarding methodological limitations in establishing levels of TBI and its potential relevance to determinations of feigned cognitive impairment. We hope that these spirited discussions will stimulate a much-needed review and a fundamental revamping, if not replacement, of the MND model. 相似文献

This study examines the effects of taphonomic processes on blunt force trauma (BFT) through an experimental study involving pig heads. Of particular concern is the possibility that taphonomic changes can create pseudo-trauma and/or conceal evidence of actual trauma. BFT was inflicted on 10 pig skulls using a hammer. The skulls were subsequently exposed to the environment for 12 months. Seven taphonomic changes were evaluated: the freeze-thaw cycle; rodent gnawing; carnivore scavenging; presence/weight of soil; presence/weight of rain and snow; movement/displacement of bones; and discoloration due to sun bleaching and grass staining. Taphonomic effects varied between cancellous, compact, fresh, and degreased bone. Freezing and thawing, exposure to rain and snow, movement of the skulls, and soil erosion altered and, in some cases disguised, pre-existing trauma. Rodent and carnivore activity did not obliterate evidence of BFT. Recommendations for evaluating BFT on remains affected by taphonomic processes are presented. As each taphonomic process outlined by this study has the potential to disguise antemortem injury, the authors propose that one must carefully examine large, circular openings in the skull that may represent the remnant evidence of BFT. 相似文献

Autosomal STR typing alone seems to be no sufficient tool for resolving deficiency cases (e.g. cases of questioned paternity or half-sibships). Therefore, we investigated whether the additional analysis of RFLP single locus probes can improve the solution of such complicated kinship cases. We analyzed 207 children and men from 101 families using the AmpFlSTRIdentifiler multiplex PCR kit and three RFLP single locus probes. A comparison between each child and all unrelated men resulted in 11,023 man / child pairs. Less than three excluding STRs were found in 125 child / unrelated man pairs (1.13%). Additional analysis of RFLP results reduced the number of ambiguous cases to 35. Half-sibling pairs were simulated using STR results from 20 cases with high paternity probabilities (group 1) and relatively low paternity probabilities (group 2). Using a commercially available computer program we calculated probabilities for 778 half-sibling pairs. In 35 pairs (4.49%) half-sibling probabilities over 90.0% could be calculated. Additional investigation of RFLP single locus probes did not lead to a more reliable evaluation of these results. The combined investigation of autosomal STRs and RFLP single locus probes can satisfactorily solve deficient paternities but does not contribute to the solution of questioned half-sibships. 相似文献

Abstract: This study evaluates the use of polydimethylsiloxane polymer composites (PDMS, Fe–PDMS) as a passive sampling media to preconcentrate analytes found in environmental settings. Samplers were made using commercially available silicone products. The composite samplers were assessed for their sorption properties using Atrazine and Irgarol 1051 as model compounds. The initial study assessed the utility of PDMS sheets as adsorption material by following analyte depletion from spiked water samples by solid‐phase microextraction gas chromatography/mass spectrometry (GC/MS). Follow‐up studies conducted at high and low concentrations using lab manufactured iron‐ PDMS rods (Fe–PDMS) showed effective uptake at differential rates from concentrations ranging between 1 μg/L and 10 μg/L. Adsorption mechanism was reversible, and compounds were recovered from the exposed materials and analyzed by liquid–liquid extraction‐GC/MS. Both composites showed better affinity for Irgarol 1051, 100% removal, than for Atrazine, 30% removal, likely representing their KOW differences, 3.6 and 2.6, respectively. This “proof of concept” study demonstrates the positive implications for the use of silicon polymer composites as a monitoring tool for environmental forensic purposes. 相似文献

In this paper we argue that the theoretical work of Goffman (1961) on “total institutions,” Foucault’s (1977) insights into the workings of disciplinary power, and an account of contemporary forms of punishment and social control
in postmodern society (Staples 2000) help us better understand the experiences of those individuals sentenced to house arrest. Based on face-to-face interviews
with twenty-three people being electronically monitored in a Midwestern metropolitan area, our analysis identifies three themes
that illustrate the ways in which electronic monitoring is experienced as a complex amalgam of what Goffman (1961, p. 13) saw as the distinct “home world” and the “institutional world”. These themes include (1) “Home is Where the Machine Is,” (2) “Producing Docile Bodies,” and (3) “Threat of Sanctions”. We reassert our claim (Staples 1994, 2000) that contemporary forms of social control such as electronic monitoring reflect an ongoing struggle to deal with problems
and issues set in motion with the birth of modernity. 相似文献
