Sexual Dimorphism of Maxillary Sinus Dimensions Using Cone‐Beam Computed Tomography

Sex determination of unknown persons plays an important role in forensic medicine. Cone‐beam computed tomography (CBCT) is an excellent imaging modality for accurate measurement of maxillary sinus dimensions. This study aimed to evaluate whether maxillary sinus measurements on CBCT scans can be applied for sex determination. The width, length, and height of maxillary sinuses in CBCT images of 100 patients (50 males and 50 females) were measured. Student's t‐test and discriminant function analysis were used to compare differences in the measured parameters between males and females. The correct predictive accuracy rate of sex determination was 78% in females and 74% in males with overall accuracy of 76%. Based on discriminant analysis, the most pronounced variable in differentiation of sex groups was maxillary sinus height. This study suggests that maxillary sinus measurements can be valuable for sex determination in forensic investigation, especially for cases in which other traditional methods are not applicable.     

The indirectly generated tainted truth effect: warning is not necessary to worsen the testimony of non-misled persons

The purpose of the present research was to examine the indirectly generated tainted truth effect (TTE). The TTE refers to decreased accuracy on a memory test among persons who are erroneously warned about non-existent misinformation in material that describes an event. It was expected that the TTE would occur even without an explicit warning about misinformation, if one distinctive item of misinformation appeared in postevent material that also contained correct information that was consistent with the original material about the event (indirectly generated TTE: IGTTE). Experiment 1 produced the IGTTE and this effect was replicated in Experiment 2. Experiment 2 showed that the classic and indirect versions of the TTE usually occurred among persons who incorrectly monitored the source of information. Experiment 3 replicated the IGTTE using a procedure that included an additional phase between presenting the original and postevent material – initial testing. When the initial testing procedure was administered in Experiment 3, the TTE was smaller; however, this initial testing procedure had no effect on the IGTTE.     

马克思主义军事真理预设论的哲学追问

马克思和恩格斯是无产阶级军事科学的奠基人,军事真理预设论是其全部军事理论的奠基石之一。在哲学层次上,"倾心为人类赢得有意义的军事世界"、"反思批判思想前提的前提思想"、"从不确定性出发探寻确定性的奥秘",分别构成了马克思主义军事真理预设论的根本旨趣、逻辑支点和立足基点。     

被害人承诺问题研究

被害人承诺,是现代社会广泛认可、但我国刑法中没有明文规定的排除犯罪性事由。其法理基础是,刑法以保护个人利益为首要任务,被害人自愿放弃的利益不在刑法的保护范围之内。被害人承诺的适用范围,应是除了侵害生命之外的一切侵害个人利益的犯罪;被害人承诺的成立条件,必须从体现被害人的真实意思的角度来考虑;被害人只有在有关法益处分的决定上具有错误的场合,其承诺才无效;推定承诺,兼具被害人的现实承诺和紧急避险的特征,其适用要受到严格限制。     

基于数据挖掘实现成人喉软骨和舌骨CT图像重组的年龄推断

目的 运用数据挖掘技术探索喉软骨和舌骨CT图像重组用于成人年龄推断的可行性.方法 收集413例颈部薄层CT图像,样本年龄范围18～<80岁,将样本随机分为测试集和训练集.参照TURK等的分级方法,对所有样本进行全方位综合阅片分级,将甲状软骨骨化过程分为6级,环状软骨骨化过程分为5级,舌骨大角和舌骨体的骨性结合分为3级....     

真理标准问题讨论的历史作用新思考

在改革开放历程之中．真理标准问题大讨论从“实、真、人”的三个层面冲破了“两个凡是”的禁锢,摆脱了长期以来“左”倾错误思想的束缚。它促进了实践理性的回归、实现了科学精神的重塑、加速了“斗争哲学”的终结、彰显弘扬了人本主义。它是思想解放的先声．在社会主义现代化建设进程中发挥出独特和巨大的历史作用。     

精神障碍与刑事责任能力的判定

刑事责任能力应当是指行为当时的犯罪能力,即责任应答的能力,而并非刑罚适应能力.根据刑法立法史,我国刑法中的精神病概念应当作广义的理解,而在其判定中,应当明确法官判断的优越性,医学鉴定不能约束法官的判断.     

再学列宁《青年团的任务》的几点思考

列宁在俄国共产主义青年团第三次全国代表大会上,发表了著名的演说——《青年团的任务》。在《青年团的任务》中,列宁明确提出青年的任务是学习并指明了学习方向。今天再学习《青年团的任务》,理解、研究其基本思想,对于我们做好青年工作具有重要的指导意义。我们应教育、引导当代青年,特别是当代大学生结合社会主义建设实践进行学习,努力培养广大青年求真务实的精神;自觉树立正确的社会主义荣辱观;掌握建设现代化的本领;成为“四个新一代”要求的社会主义事业的建设者和接班人。     

风险自负原则在我国学校体育伤害中的合理适用

作为一项重要的减免责事由,风险自负原则更适应体育活动的特点,适合解决体育运动伤害归责问题。当前,我国学校体育伤害面临着过失认定不明、责任划分不清、公平原则过度适用等问题,以风险自负解决学校体育纠纷,具有特别意义。在学校体育伤害中正确适用风险自负原则,需分清固有风险的范围,明确各方责任,采用以客观标准为准则、辅之主观标准的过失认定方法,并将公平责任类型化,进而平衡学校、家长、学生三方的权益。     

与时俱进、开拓创新是解放思想、实事求是的必然要求

从马克思辩证唯物主义认识论的角度来看,与时俱进、开拓创新与我们党的解放思想、实事求是的思想路线是一致的解放思想、实事求是的思想路线是与时俱进、开拓创新精神的思想前提和理论基础;与时俱进、开拓创新是解放思想、实事求是的辩证思维和唯物主义精神的必然要求和现实体现;与时俱进、开拓创新的精神与解放思想、实事求是的思想路线统一于党的全部理论与实践之中.
