Psilocin (4-hydroxy-N,N-dimethyltryptamine, 4-HO-DMT) and bufotenine (5-hydroxy-N,N-dimethyltryptamine, 5-HO-DMT), which are both naturally occurring compounds, are classified as controlled substances in numerous countries due to their pharmacological activities and recreational usage. There are two other benzene ring regioisomers, 6-hydroxy-N,N-dimethyltryptamine (6-HO-DMT) and 7-hydroxy-N,N-dimethyltryptamine (7-HO-DMT), which are not classified by name as controlled substances, and which were synthesized for this current work. The four isomers were analyzed using routine methodologies employed by the Israel's Police Division of Identification and Forensic Science (DIFS) Laboratory, namely thin layer chromatography (TLC), Fourier transform infrared spectroscopy (FTIR), and gas chromatography mass spectroscopy (GC-MS). It was found possible to differentiate the four isomers. Forensic specimens that were suspected to be psilocybe mushrooms were examined, confirming that it is now possible to unequivocally identify the presence of psilocin and rule out the presence of its other isomers. 相似文献

What variables lead judicial and nonjudicial decision‐making bodies to introduce policy change? In the theoretical framework proposed, the path‐dependent nature of law has a differential impact on courts and legislatures. Likewise, certain political institutions including elections and political accountability lead those bodies to introduce policy change under dissimilar circumstances. Global trends, however, affect both institutional paths equally. We test this theory with data for the repeal of sodomy laws in all countries from 1972–2002. Results from two disparate multivariate models overwhelmingly confirm our predictions. The unique institutional position of courts of last resort allows them to be less constrained than legislatures by either legal status quo or political accountability. Globalization, on the other hand, has a comparable effect on both. This work is path breaking in offering a theoretical framework explaining policy change via different institutional paths, systematically testing the framework comparatively and with respect to a policy issue still on the agenda in many countries. 相似文献

A new pairwise osteometric pair‐matching approach based on the Z‐transform method is presented. In contrast to previous methods that perform a global t‐test on the summed skeletal element pair measurement distances, this approach performs t‐tests on each individual distance, facilitating the capture of measurement‐specific variation. This new approach is compared to published pairwise sorting methods using a standard reference dataset of postcranial remains maintained by the Defense POW/MIA Accounting Agency. Receiver operating characteristic curve analysis indicates significantly improved performance for the clavicle and radius over all previous methods (p < 0.01). The z‐transform method weighted by the effect size outperformed the t‐test (Byrd and Adams) and the mean t‐test (Lynch) for all elements (p < 0.01). The method performed better than the absolute value t‐test (Lynch) for five elements (p < 0.01) and performed at least as well for the remainder. To facilitate usability all methods are available at: https://github.com/spawaskar-cora/z-transform-method . 相似文献

In recent decades (the ?post-heroic‘ condition) - threats of widespread selective conscientious objection have become a political tool to advance opposing political agendas in Israel. This article examines attitudes amongst the Israeli public concerning the legitimacy of demands that different groups of soldiers be exempted from military operations to which they are ideologically opposed (such as serving in the occupied territories or, conversely, participating in evacuation of settlements). The results point to a multi-cultural model embracing diversity management not as a neo-liberal ideal but rather as a strategy for co-option, containment and inclusion, with a view to preserving the “people's army” model. 相似文献

- In this commentary, written by senior commentator and presidential advisor Michael Sommer, who served all three Kennedy brothers, the author argues that the dying Senator Ted Kennedy has always truly fought for all Americans, has opponents but no enemies, that the world knows it, and that his liberalism is “the best American political philosophy” that America has. The author maintains that the Senator “represents the best that is in Americans, what America really stands for,” and that the world recognizes that, too. The author believes that President‐elect Obama will once again vigorously show the world the same Kennedy‐like enabling vision, hope, great leadership and true American spirit, that the world has tragically missed from America for the past eight years.
