基于内存中的网络传输数据结构获取电子数据

电子数据取证实践中,获取嫌疑人进行网络信息传输涉及的IP地址、端口号、MAC地址以及对应进程信息,有助于全面深入揭示嫌疑人网络犯罪行为。基于IPv4首部、sockaddr_in、_TCPT_OBJECT、Ethernet V2标准MAC帧等四种数据结构于内存中的具体格式,归纳总结用于定位相关结构的特征关键字,同时通过实例说明提取网络传输电子证据的方法,并对过程中涉及的具体技术与注意事项予以阐述。电子数据取证实践证明,所述方法准确高效。     

互动——对外开放酝酿的显著特点

互动是十一届三中全会前夕对外开放酝酿的显著特点。正是由于国内外互动、中国共产党高层内部互动、社会及党内上下思想互动,对外开放意见和想法激烈碰撞、融合,在取得对外开放共识基础上,对外开放基本国策最终确立。     

《婚姻法》第 17 条第 4 项立法之商榷———兼论婚后继承或受赠财产的权利属性

《婚姻法》第 17 条第 4 项关于婚后继承或受赠财产原则上为夫妻共同财产的规定，引发了立法、司法和社会生活中的诸多问题。从共同财产认定的法理基础、该条与《婚姻法》第 18 条第 3 项之间的法律困惑、法律在本土化过程中出现的错误、该条存在的法律漏洞以及与相关法律的冲突等角度进行分析，提出废除该条款的立法建议。     

贯彻党的十七届四中全会精神 提高社会主义学院教学科学化水平

党的十七届四中全会通过的<中共中央关于加强和改进新形势下党的建设若干重大问题的决定>对于社会主义学院建设具有重要意义.学习贯彻党的十七届四中全会精神,最重要的是"提高党的建设科学化水平".这一要求集中体现了中国特色社会主义理论体系对党的建设的指导作用.社会主义学院发展特别是教学工作面临的突出问题是提高科学化水平的问题,也要以科学理论来指导,以科学制度来保障,以科学方法来推进.     

决策树算法在未成年人犯罪成因中的应用研究

犯罪成因的分析在未成年人犯罪研究中起着重要的作用，而分类算法在分析犯罪成因上是卓有成效的。决策树算法是分类算法中一类重要的算法，其中以C4．5算法最为流行，但这种算法在时间复杂性和增量式学习方面还不是很理想，因此有必要对其进行改进。     

提高大学英语四级完形填空成绩的策略研究

A unified model of settlement and trial expenditures: The Priest–Klein model extended

Settlement and trial expenditures are crucially interrelated. The literature on settlement, however, takes no account of models of trial. In this paper, we develop a unified model of settlement and trial expenditures. We do this by discarding the usual assumption of settlement models that trial costs are constant across cases. Instead, we follow the literature on trial by permitting trial costs to vary with the legal merit of the plaintiff's case. Our approach can be used to extend standard models of settlement such as the well-known Priest–Klein model as well as models based on asymmetric information. As a demonstration, we extend the Priest–Klein model and generally overturn that model's canonical results. In particular, we show that even in a fully symmetric model, predicted win rates at trial can deviate substantially from 50 percent. Furthermore, win rates will vary in response to legal reforms that shift the decision standard.     

Analysis of Ecstasy Tablets Using Capillary Electrophoresis with Capacitively Coupled Contactless Conductivity Detection

A method for the identification of 3,4‐methylenedioxymethamphetamine (MDMA) and meta‐chlorophenylpiperazine (mCPP) was developed employing capillary electrophoresis (CE) with capacitively coupled contactless conductivity detection (C⁴D). Sample extraction, separation, and detection of “Ecstasy” tablets were performed in <10 min without sample derivatization. The separation electrolyte was 20 mm TAPS/Lithium, pH 8.7. Average minimal detectable amounts for MDMA and mCPP were 0.04 mg/tablet, several orders of magnitude lower than the minimum amount encountered in a tablet. Seven different Ecstasy tablets seized in Rio de Janeiro, Brazil, were analyzed by CE‐C⁴D and compared against routine gas chromatography‐mass spectrometry (GC‐MS). The CE method demonstrated sufficient selectivity to discriminate the two target drugs, MDMA and mCPP, from the other drugs present in seizures, namely amphepramone, fenproporex, caffeine, lidocaine, and cocaine. Separation was performed in <90 sec. The advantages of using C⁴D instead of traditional CE‐UV methods for in‐field analysis are also discussed.
