Governance of Dual-Use Technologies: Theory and Practice
The term dual-use characterizes technologies that can have both military and civilian applications. What is the state of current efforts to control the spread of these powerful technologies—nuclear, biological, cyber—that can simultaneously advance social and economic well-being and also be harnessed for hostile purposes? What have previous efforts to govern, for example, nuclear and biological weapons taught us about the potential for the control of these dual-use technologies? What are the implications for governance when the range of actors who could cause harm with these technologies include not just national governments but also non-state actors like terrorists? These are some of the questions addressed by Governance of Dual-Use Technologies: Theory and Practice, the new publication released today by the Global Nuclear Future Initiative of the American Academy of Arts and Sciences. The publication's editor is Elisa D. Harris, Senior Research Scholar, Center for International Security Studies, University of Maryland School of Public Affairs. Governance of Dual-Use Technologies examines the similarities and differences between the strategies used for the control of nuclear technologies and those proposed for biotechnology and information technology. The publication makes clear the challenges concomitant with dual-use governance. For example, general agreement exists internationally on the need to restrict access to technologies enabling the development of nuclear weapons. However, no similar consensus exists in the bio and information technology domains. The publication also explores the limitations of military measures like deterrence, defense, and reprisal in preventing globally available biological and information technologies from being misused. Some of the other questions explored by the publication include: What types of governance measures for these dual-use technologies have already been adopted? What objectives have those measures sought to achieve? How have the technical characteristics of the technology affected governance prospects? What have been the primary obstacles to effective governance, and what gaps exist in the current governance regime? Are further governance measures feasible?

Scalable simultaneous multi-qubit readout with 99.99% single-shot fidelity
We describe single-shot readout of a trapped-ion multi-qubit register using
space and time-resolved camera detection. For a single qubit we measure
0.9(3)x10^{-4} readout error in 400us exposure time, limited by the qubit's
decay lifetime. For a four-qubit register (a "qunybble") we measure an
additional error of only 0.1(1)x10^{-4} per qubit, despite the presence of 4%
optical cross-talk between neighbouring qubits. A study of the cross-talk
indicates that the method would scale with negligible loss of fidelity to
~10000 qubits at a density <~1 qubit/um^2, with a readout time ~1us/qubit.Comment: 4 pages, 3 figures; simulations added to fig.3, with some further
text and figure revisions. Main results unchanged
The role of soil biotic processes in the search of quantitative indexes of soil quality
Non-Peer ReviewedMonitoring soil quality involves measurements of soil properties over periods of several years. This article
examines the potential role of chemical SOM composition and of soil biotic processes as faster indexes of soil quality. Soil quality was quantified on the basis of individual soil attributes and time. Chemical characterization of soil organic matter by solid 13C-NMR and Py-FIMS showed that a degraded Gleysol cropped to corn during 25 years suffered C losses from all chemical functional groups. Surprisingly, aromatic-C was lost at proportional higher rates than aliphatic-C. These results indicate that chemical composition of SOM determined by quantitative nondestructive methods can be used as quality indexes in
agricultural soils. Biotic processes reflect changes in soil quality over shorter periods than total or type of SOM. Microbial specific respiration (qCO2) is a soil attribute that consistently reflected differences in soil quality. It was hypothesized that qCO2 , the microbial adenylate energy charge and anabolic reduction charge may permit to asses soil quality over monitoring periods of weeks to <5y
The Lockheed OSO-8 program. Analysis of data from the mapping X-ray heliometer experiment
The final report describes the extent of the analysis effort, and other activities associated with the preservation and documentation of the data set are described. The main scientific results, which are related to the behavior of individual solar activity regions in the energy band 1.5 - 15 keV, are summarized, and a complete bibliography of publications and presentations is given. Copies of key articles are also provided
Shared Responsibilities for Nuclear Disarmament: A Global Debate
Presents Sagan's 2009 paper calling for rethinking the balance of responsibilities and the relationship between articles in the Nuclear Non-Proliferation Treaty with seven response papers by international scholars about how to pursue nuclear disarmament
Preliminary evidence supporting the use of equine science podcasts to bridge the gap between scientists and horse enthusiasts to improve horse welfare.:Preliminary evidence of podcast impacts on equine welfare
SummaryBackground Podcasts have become a popular digital forum for discussing scientific information with peers, as well as with the non-scientific community, often referred to as ‘edutainment’. It is unclear how science-based podcasts can support the veterinary industry through, for example, supporting good husbandry practices.ObjectivesTo understand the influence of ‘edutainment’ on equine owners’ husbandry decisionsStudy DesignThe sample population was listeners of the Conversations in Equine Science (CES) podcast recruited to complete an online survey via a link promoted by the CES hosts. The survey contained Likert-like questions assessing how listeners rated the importance of different forms of evidence when making husbandry decisions and questions relating to husbandry changes made. MethodsA mixed methods approach was used to analyse the data. The Likert package for R was used to explore importance ratings. Free text questions were analysed via a content analysis with a constructionist epistemological position. Results The experience of veterinarians and scientific evidence was considered the most important forms of evidence that owners used when making decisions about their horse’s management (93% agreed and 91% agreed they were important respectively). Additionally, 74% of respondents had made a change to the management or training principles prompted by an episode of CES, suggesting edutainment can be a prompt to management change. Of these, the majority (55%) had done so based on a joint discussion of the podcast and their own reading of the evidence.Main LimitationsThis was an opportunistic sample of those already invested in the edutainment format, and may not represent those owners with no interest in scientific evidence. Conclusions Podcasts are an easy-access, low-cost medium to convey research and current trends in the equine/equitation science genre. They may be a valuable tool for the veterinary industry to employ to support horse welfare. <br/
