网络环境下版权保护体系的构筑

网络环境下如何构筑版权保护体系是网络时代迫切需要解决的问题,笔者认为应当从法律实现和社会实现两个角度来实现对版权保护,并提出了一些具体的想法。     

公共行政执行协同机制——概念、模型和理论视角

公共行政执行协同机制的EPDFIIE模型是分析公共行政执行协同机制的一个概念框架,这一概念框架描述了公共行政执行的生态协同机制、政治—行政协同机制、决策—执行—监督协同机制、职能—结构协同机制、部际协同机制、府际协同机制和嵌入性协同机制的基本内容、理论视角和这些机制之间的有机联系。     

十六大以来中国特色社会主义建设快速稳步发展的主要经验及启示

十六大以来中国特色社会主义快速稳步发展的主要经验包括:一是以理论创新为牵引;二是以加强执政能力和先进性建设作为党的建设的重中之重;三是以深化改革、扩大开放为动力;四是以民生为根本。它们为中国特色社会主义快速稳定发展提供了新的理论指导,有力的政治保障,良好的环境支持,新的力量之源。快速稳步发展的启示是:中国特色社会主义道路是一条民族振兴和人民幸福的成功之路、胜利之路;中国特色社会主义在新世纪要大发展,必须全面贯彻和落实科学发展观;中国特色社会主义的内涵与整体形象,在实践中已经显露出美好的发展前景。     

弘扬与时俱进的理论品质把握科学发展观的深刻内涵

与时俱进是马克思主义的基本理论品质,是中国共产党保持强大生命力的根本要求,理论创新和实践创新是马克思主义与时俱进品质的具体体现,科学发展观是马克思主义基本理论的再发展,是推动中国社会主义现代化建设的重要理论命题.

Analysis of Δ-tetrahydrocannabinol in oral fluid samples using solid-phase extraction and high-performance liquid chromatography–electrospray ionization mass spectrometry

An analytical method using solid-phase extraction (SPE) and high-performance liquid chromatography–mass spectrometry (LC–MS) has been developed and validated for the confirmation of Δ⁹-tetrahydrocannabinol (THC) in oral fluid samples. Oral fluid was extracted using Bond Elut LRC-Certify solid-phase extraction columns (10 cm³, 300 mg) and elution performed with n-hexane/ethyl acetate. Quantitation made use of the selected ion-recording mode (SIR) using the most abundant characteristic ion [THC + H⁺], m/z 315.31 and the fragment ion, m/z 193.13 for confirmation, and m/z 318.00 for the protonated internal standard, [d₃-THC + H⁺]. The method proved to be precise for THC, in terms of both intra-day and inter-day analyses, with coefficients of variation less than 10%, and the calculated extraction efficiencies for THC ranged from 76 to 83%. Calibration standards spiked with THC between 2 and 100 ng/mL showed a linear relationship (r² = 0.999). The method presented was applied to the oral fluid samples taken from the volunteers during the largest music event in Portugal, named Rock in Rio-Lisboa. Oral fluid was collected from 40 persons by expectoration and with Salivette^®. In 55% of the samples obtained by expectorating, THC was detected with concentration ranges from 1033 to 6552 ng/mL and in 45% of cases THC was detected at concentrations between 51 and 937 ng/mL. However, using Salivette^® collection, 26 of the 40 cases had an undetectable THC.
