Patent Office as Biosecurity Gatekeeper: Fostering Responsible Science and Building Public Trust in DIY Science, 10 J. Marshall Rev. Intell. Prop. L. 423 (2011)

When the fields of intellectual property law and biotechnology intersect, most analysis is driven byeconomic and ethical issues. This article examines these factors, but in relation to the emerging security threat posed by biohackers, or do-it-yourself (“DIY”) scientists, who operate free from oversight and industry norms at the fringes of the biotechnology community. Public health risks are poised to grow as these citizen-scientists race for lucrative discoveries in the new frontier of syntheticbiology. This article proposes that the existing paradigm adjust accordingly to leverage regulatory compliance from the most ambitious biohackers looking to benefit from patent protection. The U.S. government could bring aspiring entrepreneurial biohackers into the fold by making non-institutional patent applicants undergo Center for Disease Control biosafety training, personnel screening, and lab registration one year prior to receiving patent application eligibility in order to reduce some of the potential risk of these unmonitored labs present

User acceptance of intelligent avionics: A study of automatic-aided target recognition

User acceptance of new support systems typically was evaluated after the systems were specified, designed, and built. The current study attempts to assess user acceptance of an Automatic-Aided Target Recognition (ATR) system using an emulation of such a proposed system. The detection accuracy and false alarm level of the ATR system were varied systematically, and subjects rated the tactical value of systems exhibiting different performance levels. Both detection accuracy and false alarm level affected the subjects' ratings. The data from two experiments suggest a cut-off point in ATR performance below which the subjects saw little tactical value in the system. An ATR system seems to have obvious tactical value only if it functions at a correct detection rate of 0.7 or better with a false alarm level of 0.167 false alarms per square degree or fewer

Gender-based perceptions of the 2001 anthrax attacks: Implications for outreach and preparedness

Extensive research dealing with gender-based perceptions of fear of crime has generally found that women express greater levels of fear compared to men. Further, studies have found that women engage in more self-protective behaviors in response to fear of crime, as well as have different levels of confidence in government efficacy relative to men. The majority of these studies have focused on violent and property crime; little research has focused on gender-based perceptions of the threat of bioterrorism. Using data from a national survey conducted by ABC News / Washington Post, this study contrasted perceptions of safety and fear in response to anthrax attacks among male and female respondents. Results indicated some gender differences in perceptions and responses to possible anthrax exposure, although not all achieved statistical significance. Results are discussed in relation to their implications for criminological theory, security and bioterrorism preparedness

Supercritical Water Gasification: Practical Design Strategies and Operational Challenges for Lab-Scale, Continuous Flow Reactors

Optimizing an industrial-scale supercritical water gasification process requires detailed knowledge of chemical reaction pathways, rates, and product yields. Laboratory-scale reactors are employed to develop this knowledge base. The rationale behind designs and component selection of continuous flow, laboratory-scale supercritical water gasification reactors is analyzed. Some design challenges have standard solutions, such as pressurization and preheating, but issues with solid precipitation and feedstock pretreatment still present open questions. Strategies for reactant mixing must be evaluated on a system-by-system basis, depending on feedstock and experimental goals, as mixing can affect product yields, char formation, and reaction pathways. In-situ Raman spectroscopic monitoring of reaction chemistry promises to further fundamental knowledge of gasification and decrease experimentation time. High-temperature, high-pressure spectroscopy in supercritical water conditions is performed, however, long-term operation flow cell operation is challenging. Comparison of Raman spectra for decomposition of formic acid in the supercritical region and cold section of the reactor demonstrates the difficulty in performing quantitative spectroscopy in the hot zone. Future designs and optimization of SCWG reactors should consider well-established solutions for pressurization, heating, and process monitoring, and effective strategies for mixing and solids handling for long-term reactor operation and data collection

Optical Characterization of Ceramic Thin Films: Applications in Low-temperature Solid Oxide Fuel-Cell Materials Research

Characterization of thin film solid oxide fuel-cell materials can be difficult due to the range of porosities in electrodes and electrolytes as well as the nano-sized pores and particles. In this study, optical characterization techniques such as ultraviolet-visible transmission and reflection spectrophotometry are illustrated as methods for achieving information about the film density from the film refractive index as well as the film thickness. These techniques were used to investigate the sintering process of colloidal CeO2 on sapphire substrates and polymeric precursor-derived ZrO2:16%Y (YSZ) thin films on silicon over the temperature range 400-1000 °C, and the results were compared with traditional characterization techniques such as electron microscopy, profilometry, ellipsometry, and x-ray diffraction line broadening analyses. Most of the techniques were in good agreement with the CeO2 grain size changing from 5-65 nm and the film thickness changing from 0.8-0.5 µm. Comparisons of transmission and reflection spectrophotometry with ellipsometry illustrated that scattering effects from the porous CeO2 films caused an overestimation of the refractive index from ellipsometry, but allowed for accurate grain size measurements from transmission and reflection data. Both techniques were in good agreement during the sintering of the YSZ thin films, with the density changing from 90-100% theoretical after heating between 400 and 800 °C
