21世纪初国际能源格局及今后的中长期变化 ——兼论日本能源安全的出路与困境

为了应对全球气候变化，需对能源安全概念进行“范式转换”，即能源安全不仅要包括能源供需矛盾、能源供需网络的脆弱性和潜在风险，而且要与环境安全、水安全相结合，形成“广义的能源安全”概念。当前，一系列新因素正在使国际能源格局和能源范式发生重大变化：福岛核电站特大事故严重影响了全球公众对核安全的信心，今后世界各国发展核电会更加谨慎；可再生能源日益发展与普及；气候变暖正在改变能源资源与环境资源相加的自然资源“总格局”；非常规油气资源日益开发、天然气地位上升以及美洲能源供给新轴心崛起；“可燃冰革命”及海洋能源进一步开发。在福岛核事故后，日本能源安全既面临风险，又面临机遇。今后日本能源安全战略的动向主要是：坚持发展核电，但会更加谨慎稳健；积极开展能源外交，实现能源来源多元化；在一次能源结构中增大天然气的比重；大力发展可再生能源和节能；大力开发可燃冰等海洋能源资源。此外，当前日本政府错误的周边外交政策将成为日本能源安全最大的潜在风险，可望长期执政的自民党政权采取的鹰派民族主义政策，终将给日本惹祸，首当其冲的祸害对象就是日本的能源安全。

酮洛芬注射液在乳牛体内的残留消除研究

为建立牛乳中酮洛芬的液相色谱-串联质谱(LC-MS/MS)检测方法,牛乳样品经甲醇提取,C18色谱柱分离,采用正离子模式,多反应监测,内标法定量。结果表明,牛乳中酮洛芬的检出限为1μg/kg,定量限为5μg/kg,在5~200μg/kg范围内线性关系良好,相关系数大于0.99。在25~100μg/kg添加水平的回收率为93.3%~107.5%,批内、批间相对标准偏差分别为1.72%~5.46%、1.13%~7.04%。该方法高效、灵敏、准确,可作为牛乳中酮洛芬的检测方法。选用20头健康的泌乳期荷斯坦乳牛,高产、低产各10头,以3 mg/kg剂量肌内注射给药,每天1次,连用3 d,分别于每次给药后第2、15小时采集乳样。每次给药后2 h牛乳中可检出酮洛芬,最高质量分数为(38.43±3.90)μg/kg,停药后15 h均未检出。所有时间点牛乳中酮洛芬质量分数的实测结果均低于加拿大规定的最高残留限量50μg/kg,建议弃乳期为0 d。     

略论我国的综合执法

我国长期以来构建的是"全能政府",同时又缺乏严密的组织法规范,行政职能部门设置随意,导致了我国现在的行政机构林立却又权责不清、行政执法政出多门却往往执行不力等不正常现象,严重地影响了行政效率,也不利于相对人合法权益的保护.对于此,我国的<行政处罚法>和<行政许可法>试图通过设立综合执法制度来解决这些问题.近几年来,我国各地的综合执法机关越来越普遍,文章结合实践,对综合执法的含义、产生、作用、形式等问题及其发展模式试作一些粗浅的探讨.

Combined Collection and Analysis of Inorganic and Organic Gunshot Residues

Gunshot residue (GSR) analysis and their interpretation provide crucial information on a criminal investigation involving the use of firearms. To date, several approaches have been proposed for the implementation of a combined sampling and analysis of inorganic (IGSR) and organic GSR (OGSR). However, it is not clear at this stage if concurrent analyses of both types of residue might be detrimental to the analysis of IGSR currently applied in forensic laboratories. Thus, this work aims to compare and evaluate three different protocols for the combined collection and analysis of IGSR and OGSR. These methods, respectively, involve the use of a modified stub (with two halves, one for the detection of IGSR and the other for the analysis of OGSR); the sequential recovery of GSR with two stubs mounted with different adhesives (double-sided carbon tape and Tesa® TACK) and the sequential analysis of IGSR and OGSR from a single carbon stub following carbon deposition. The detection of IGSR was carried out using SEM-EDX, while OGSR analysis was performed using ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS). Obtained results for experiments performed using Geco Sinoxid^® ammunition indicated that sequential analysis was the most suitable protocol for the combined collection and analysis of both IGSR and OGSR. A higher number of inorganic (characteristic and consistent) particles and higher concentrations of ethylcentralite, N-nitrosodiphenylamine, diphenylamine, and nitroglycerin were recovered with this method.     

Nondestructive Differentiation of Polyester Single White Fibers Using Synchrotron Radiation Microbeam X-ray Fluorescence Spectrometry with Vertical Focusing

In this study, the nondestructive differentiation of individual white polyester clothing fibers was accomplished via synchrotron radiation microbeam X-ray fluorescence (SR-μ-XRF) analysis. SR-μ-XRF with vertical focusing is a useful nondestructive method for the analysis of a single polyester clothing fiber. Kirkpatrick–Baez (KB) mirror was used to vertically focus 20 keV X-rays for the analysis of 22 individual white polyester fibers taken from clothing commonly sold in Japan. SR-μ-XRF with a vertical focused 2 μm (V) × 300 μm (H) beam was approximately 12.8 times more sensitive than SR-XRF with an unfocused 300 μm (V) × 300 μm (H) beam for the detection of elements in single fibers. The minimum detection limits (MDLs) of the SR-μ-XRF method were 8.15 ppm for Cl and 0.06 ppm for Br. In addition to Ti in TiO₂ delustering agents, Zr and Nb impurities in the delustering agents were detected in individual fibers. Sb from a polymerization catalyst and Co from a transesterification catalyst were also detected in individual fibers. Comparing the Ti K_β/Sb L_α,β and Zr K_α/Nb K_α X-ray intensity ratios was a useful way to distinguish individual clothing fibers, and 98% of the fibers were differentiated when additional trace elements were used as discrimination indicators.     

网络传销犯罪的司法认定逻辑及其修正

基于传销犯罪的诈骗本质以及网络传销所衍生的诸多形式,原有的组织、领导传销活动罪的界定已经无法适应惩治网络传销犯罪的需要,应当基于体系与实践的双重考量,对网络传销犯罪的立法和司法作出相应的调适。组织、领导传销活动罪与集资诈骗罪系交叉竞合关系,两者在量刑上应保持平衡。网络传销犯罪在法益侵害程度方面未必高于传统传销犯罪。司法解释性文件对于网络传销犯罪的认定不应囿于组织内部参与传销活动人员30人三级的标准。网络团队计酬不应当构成犯罪。对于混合型传销,则应当结合"骗取财物"的要件予以全面判断。对为网络传销犯罪提供网络服务的行为,应区分情况适用共同犯罪、非法利用信息网络罪与帮助信息网络犯罪活动罪。对网络传销犯罪作证据综合认定时,应优先客观性证据,确立互联网电子数据的中枢证明作用,修正逐一收集参与传销活动人员的言词证据规则。
