At the same time, some ethicists argue that AI should be given moral status, holding them responsible for their actions. Sparrow opposed Putnam’s view of computational functionalism through his thought experiment of constructing the Turing triage test, as well as the construction of a moral machine. He argues that AI lacks an “inner life” in an ontological sense, has no “potential for punishment,” and thus has no moral standing. However, in Sparrow’s thought experiment, there is no strict distinction between “moral agent” and “moral patient”, so that in Sparrow’s argument, the definition of AI’s moral status is vague. Still, Sparrow’s thought experiment is instructive.展开更多

METHODS： The in vivo sucrose permeability test was administered to healthy controls, to Barrett＇s patients and to non-Barrett＇s patients on continuous PPI thera- py. Degree of leak was tested for correlation with pres- ence of Barrett＇s, use of PPIs, and length of Barrett＇s segment and duration of PPI use. RESULTS： Barrett＇s patients manifested a near 3-fold greater, upper gastrointestinal sucrose leak than healthy controls. A decrease of sucrose leak was ob- served in Barrett＇s patients who ceased PPI use for 7 d.Although initial introduction of PPI use （in a PPI-na＇ive population） results in dramatic increase in sucrose leak, long-term, continuous PPI use manifested a slow spon- taneous decline in leak. The sucrose leak observed in Barrett＇s patients showed no correlation to the amount of Barrett＇s tissue present in the esophagus. CONCLUSION： Although future research is needed to determine the degree of paracellular leak in actual Barrett＇s mucosa, the relatively high degree of leak ob- served with in vivo sucrose permeability measurement of Barrett＇s patients reflects their PPI use and not their Barrett＇s tissue perse.展开更多

Multiple aggregates and emulsions are evaluated with existing test methods and with modified equipment and methods. The results indicate the current test tray is inadequate and that a thicker tray provides better results. Conditioning that incorporated either freeze times between 4 to 8 hours and/or freeze thaw cycles were also found to be improvements to the current conditioning methods. The specified mass of the steel spheres used during the test may be too restrictive in that more economical spheres were tested and did not show differences in aggregate loss.展开更多

Price limits are artificial boundaries set by market regulators who restrict price changes of a stock to a pre-specified range during a trading day or a single trading session. The primary aim of price limit rules is to stabilize the markets during panic trading, to moderate vitality by repressing excessive speculation, and to allow stocks to be traded at prices close to their fair value. However, their impact on the market is a somewhat unresolved issue （Harris, 1998）. Using a methodology of comparing volatility based on the extreme value technique, the authors empirically investigate the impact of price limits on the volatility of the Stock Exchange of Thailand. The empirical results support price limits advocates, suggesting that price limits rules moderate stock price volatility.展开更多

The workshop concerned is a portal frame structure with four spans and two slope roofs, of which ten columns need cutting for expanding span. The design and reconstruction project of column-cut supported by joist were introduced, which includes column reinforcement, connection rebuilding between brackets and crane beams, and the changing of rigid joint into hinge joint. The construction scheme was put forward in the light of the characteristics of the reinforcement and reconstruction. Spot test of dynamic performance on the workshop and comparison with theoretical analysis results show that the column-cut supported by joist design is effective and the reconstruction project is successful.展开更多
