Comparative Bayesian Confirmation and the Quine-Duhem Problem: A Rejoinder to Strevens

By and large, we think (Strevens's [2005]) is a useful replyto our original critique (Fitelson and Waterman [2005]) of hisarticle on the Quine–Duhem (QD) problem (Strevens [2001]).But, we remain unsatisfied with several aspects of his reply(and his original article). Ultimately, we do not think he properlyaddresses our most important worries. In this brief rejoinder,we explain our remaining worries, and we issue a revised challengefor Strevens's approach to QD.

Effects of mother-son incest and positive perceptions of sexual abuse experiences on the psychosocial adjustment of clinic-referred men

OBJECTIVE: The primary objective was to examine the long-term impact of mother-son incest and positive initial perceptions of sexual abuse experiences on adult male psychosocial functioning. METHOD: Sixty-seven clinic-referred men with a history of sexual abuse participated. The participants completed self-report measures regarding their current psychosocial functioning and described the nature of their sexual and physical abuse experiences during childhood. RESULTS: Seventeen men reported mother-son incest, and these men endorsed more trauma symptoms than did other sexually abused men, even after controlling for a history of multiple perpetrators and physical abuse. Mother-son incest was likely to be subtle, involving behaviors that may be difficult to distinguish from normal caregiving (e.g., genital touching), despite the potentially serious long-term consequences. Twenty-seven men recalled positive or mixed initial perceptions of the abuse, including about half of the men who had been abused by their mothers. These men reported more adjustment problems than did men who recalled purely negative initial perceptions. CONCLUSIONS: Mother-son incest and positive initial perceptions of sexual abuse experiences both appear to be risk factors for more severe psychosocial adjustment problems among clinic-referred men.     

国产芸香科九里香属化学分类

九里香是芸香科的一个小属，主要分布于我国南部及中南半岛，少数个别品种向西南   延伸至印度和斯里兰卡及向东南伸展至澳洲东北部。  我国境内共有8种和1亚种。  九里香   属植物含丰富的生物碱和香豆精，其中包括不少生物活性成分，民间亦每每选用该属植物作传   统草药。最近又从千里香的根部分离得一种新的双吲哚生物碱，命名为月橘烯碱; 该成分有强   效的抗着床活性，对计划生育有重大意义。在发掘月橘烯碱的自然资源的研究过程中，作者分   析了国产的8种九里香属植物，发现该属植物可以划分为两组，即九里香组和棕茎组。九里香   组之成员跟棕茎组的在形态上有明显分别，而且前者之根部含抗着床成分月橘烯碱和8-戊烯   化香豆精，但后者之根部则含咔巴唑生物碱。初步分析了澳洲的卵叶九里香和泰国的暹罗九  里香，其形态及化学成分亦支持将该属分为两组。作者据此发表新组合。
