死后尸体CT在法医学鉴定中的应用价值初探

目的 对不同类型案件中的死者进行死后尸体CT扫描和常规尸体解剖,探索PMCT在法医学鉴定中的应用价值.方法 对7例因不同原因死亡的个体进行全身PMCT扫描,随后进行系统的尸体解剖,通过比较两种方法检测的结果,分析PMCT与传统尸体解剖在不同类型案件中应用的优点和不足.结果 在7个案例中,尸体上总共检出67处阳性发现.其...     

也谈中国电影工业全球化

90年代以来,世界电影工业进入以好莱坞为主导的全球化时代,中国电影工业要想融入这个圈子,就必须具备全球化思维,从市场和资源配置一体化的高度思量它的机会和选择,力求在世界电影工业的市场一体化与区域专业化过程中迎接好莱坞的电影产业转移;把握好莱坞创意动力机制全球布局的机会,为中国电影工业提供源源不断的创新和开发能力的体系。     

A Study on the Estimation of Postmortem Interval Based on Environmental Temperature and Concentrations of Substance in Vitreous Humor

A method to determine postmortem interval (PMI) based on environmental temperature and the concentrations of vitreous humor (VH) molecules were explored. Rabbit carcasses were placed in a chamber at 5, 15, 25, or 35°C, and 80–100 μL of VH was collected with the double‐eye alternating micro‐sampling method every 12 h. A Roche DPPI biochemical analyzer was used to measure the concentrations of six substances in VH samples. The interpolation function model and mixed‐effect model were employed for data fitting to establish equations for PMI estimation. The concentrations of K⁺, P, Mg²⁺, creatinine (CRE), and urea nitrogen (UN) exhibited an upward trend with increasing PMI in all temperature groups, while the concentration of Ca²⁺ showed a downward trend. Validation results using K⁺ and Mg²⁺ ions revealed that the mixed‐effect model provided a better estimation than the interpolation function model using the data from our experiment. However, both models were able to estimate PMI using temperature and VH molecule concentrations.     

建构认知——评丹尼尔·帕帕的《当代国际关系》

国际关系的基本政治环境是“安全困境”(security dilemma)。当今世界任何一个国家都不可能处在绝对安全环境中。①在国际安全困境中,各国都努力寻求摆脱困境的途径,以影响对本国安全构成威胁的环境。对于国际安全环境的理解,不同的研究取向产生不同的分析方法。理想主义学派强调把各国之间的相互依存视为维护本国安全的“公共产品”。而建构主义者认为“规范、秩序和价值观念制约国家对外政策的制订,甚至可以改变对国家利益本身的建构”。②丹尼尔.帕帕在其新版《当代国际关系:认知建构》③一书中,结构性地论述了影响当代国际关系的诸多因…
