  摘要：

  摘要：犯罪对社区造成多层次影响，给受害者带来痛苦和损失，给公众带来不安感，同时增加政府财政资源的消耗。准确识别再犯风险和确定有效的康复策略至关重要。认知和行为心理学的关键原则可以为这一任务做出贡献。本文将审查风险评估问题，并描述功能分析在法庭心理学中的适用性。作者进行的两项研究将用来阐明本文中提出的概念。本文将以一个模型结尾，该模型可能有助于指导对罪犯行为进行详细个体功能分析的现实实施。

  Direct synthesis of alkynes from inexpensive, abundant alcohols was achieved in high yields (greater than 40 examples, up to 95% yield) through a SO2F2-promoted dehydration and dehydrogenation process. This straightforward transformation of sp3-sp3 (C-C) bonds to sp-sp (C≡C) bonds requires only inexpensive and readily available reagents (no transition metals) under mild conditions. The crude alkynes

  作者：Lanlan Zhang、Chaoyue Zhao、Yang Liu、Jiancong Xu、Xiufang Xu、Zhong Jin

  DOI：10.1002/anie.201705495

  日期：2017.9.25

  Palladium‐catalyzed activation of remote meta‐C−H bonds in arenes containing tethered alcohols was achieved with high regioselectivity by using a nitrile template. Computational studies on the macrocyclic transition state of the regioselectivity‐determining C−H activation steps revealed that both the C‐N‐Ag angles and gauche comformations of phenyl ether play an extremely important role in the meta selectivity
