Commentary on Foubert, Godin, & Tatum (2010): the evolution of sexual violence prevention and the urgency for effectiveness

Foubert, Godin, and Tatum describe qualitative effects among college men of The Men's Program, a one-session sexual violence prevention program. This article and the program it describes are representative of many sexual violence prevention programs that are in practice and provide an opportunity for a brief discussion of the development and evaluation of sexual violence prevention approaches. In this commentary, we will focus on two considerations for an evolving field: the adherence to the principles of prevention and the use of rigorous evaluation methods to demonstrate effectiveness. We argue that the problem of sexual violence has created urgency for effective prevention programs and that scientific and prevention standards provide the best foundation to meet this need.     

国外主要自由贸易园区及其法律规制:评析与启示

国外主要自由贸易园区的核心特征一般包括:便利的地理区位;以获取经济利益为目标;以物流、贸易等服务业为主的综合产业结构;在贸易、投资、金融等领域实行自由政策;实行境内关外的海关监管制度。与国外主要自由贸易园区相较,广东自由贸易试验区既有共性也有差异性,其法律体系建设应基于异同之处,在管理体制、立法模式和立法内容等方面做出制度创新探索。     

技术标准中专利技术的营利模式探析与构建

技术标准中的专利技术具有其特有的技术形态、法律形态和商业形态,共同构成其形态特性.技术标准与专利技术之间的关系存在着四种基本模式,而每一种模式又分别具有不同的特性.技术标准中专利技术的营利将主要通过基本的和特殊的两个路径.然而,在技术标准中,当专利技术不得不放弃其专有的财产权利时,依然要能够营利,其实现则将要通过三个不同的阶段,这就是技术标准中专利技术营利的真正奥秘所在.     

A Strange Sort of Survival for Pinnel's Case: Collier v P & M J Wright (Holdings) Limited

This note discusses the decision of the Court of Appeal in Collier v P & M J Wright (Holdings) Limited , and notes that while the Court purports to uphold both the decision in Pinnel's Case and the effect of Re Selectmove , in fact, by an extension of promissory estoppel, it bypasses them.     

Detection of fingermarks by colloidal gold (MMD/SMD)--beyond the pH 3 limit

Dust was investigated for its ability to retain source attribution profiles (SAPs) after chemical exposure. Three distinct sources of the organophosphate pesticide acephate were investigated as a proof-of-concept model. In addition, attribution profiles were created and tested using compounds related to chemical warfare agents (CWAs), specifically VX and G-series agents: O-ethyl methylphosphonothioate (EMPTA), N,N-diisopropylmethylamine (DIPMA), N,N-diisopropylethylamine (DIEA), diisopropylamine (DIPA), diethyl aniline (DEA), diethyl ethyl phosphonate (DEEP), trimethyl phosphite (TMP), dimethyl hydrogen phosphite (DMHP), diethyl hydrogen phosphite (DEHP), triethyl phosphate (TEP), ethyl methylphosphonate (EMPA), and diisopropyl methylphosphonate (DIMP). Dust was collected from a storage shed, aliquots deposited on carpet and loaded with distinct chemical profiles using an exposure chamber and aerosolizer. After a given period of time (1h, 24h, or 72 h), the dust was extracted and its SAP analyzed by gas chromatography-mass spectrometry (GC-MS) and/or liquid chromatography-tandem mass spectrometry (LC-MS/MS). Principal components analysis (PCA) was used to determine the association of dust exposed to the same and different chemical sources. PCA results demonstrate that dust samples exposed to distinct chemical sources are clearly differentiated from one another across all collection times. Furthermore, dust aliquots exposed to the same source can be clearly associated with one another across all collection times. When the CWA-related compounds were subjected to elevated temperature (90°C) conditions, it was found that the signature was stable at the 1h and 24h collections. At 72 h and elevated temperature, larger deviations from the control were observed for some compounds. Elevated pH (10) affected the profile to a lesser degree than elevated temperature. Overall, dust is found to be an effective media for the in situ collection of source attribution profiles.     

Detection of the rare PGM1(3) allele. Further biochemical and genetic characterization of the PGM1(3) isozymes

A family possessing the rare PGM1(3) allele has been found in North Carolina, and criteria for the electrophoretic separation and accurate typing of the PGM1(3) isozymes are outlined. The PGM1(3) isozymes detected proved to be useful in helping to determine parentage in an incest investigation. The pattern of segregation of the PGM1(3) allele in four generations of this family and thermostability studies on the PGM1(3) isozymes are presented.     

Genome‐wide Screen for Individual Identification SNPs (IISNPs) and the Confirmation of Six of Them in Han Chinese with Pyrosequencing Technology*

Abstract: Single nucleotide polymorphisms (SNPs) offer promise to forensic DNA analysts, but it remains uncertain whether a panel of individual identification SNPs can be as informative as the Combined DNA Index System short tandem repeats. Based on the highly accurate and publicly available HapMap SNP database (r21a) and a minor allele frequency cutoff of ≥0.45, we completed a genome‐wide screen through 3,905,819 SNPs with internally modified computer programs and identified 1439 SNPs with high heterozygosity and low F_st values among four populations (Utah Caucasian, Han Chinese, Tokyo Japanese, and Nigerian Yoruba). Using pyrosequencing technology, we studied six loci in a relatively large group of samples to determine whether these loci were as informative as the HapMap data suggest. These SNPs performed as expected in the Han Chinese in terms of heterozygosity and F_st. The 1439 identified SNPs should provide a comprehensive and reliable set of loci for identity and relationship testing.     

Determination of γ-hydroxybutyrate (GHB) and its precursors in blood and urine samples: A salting-out approach

γ-Hydroxybutyrate (GHB) is an increasingly popular drug of abuse that causes stimulation, euphoria, anxiolysis or hypnosis, depending on the dose used. Low doses of the drug are used recreationally, and also implicated in drug-facilitated sexual assaults. Because of the unusually steep dose–response curves, accidental GHB overdosing, leading to coma, seizures or death can occur. Being a controlled substance, GHB is often substituted with its non-scheduled precursors γ-butyrolactone (GBL) and 1,4-butanediol (BD), which are rapidly metabolized into GHB in the body. Here we describe an assay for GHB, GBL and BD in blood and/or urine samples. GHB and BD were extracted from diluted 200 μL aliquots of samples with t-butylmethylether (plus internal standard benzyl alcohol) in test tubes preloaded with NaCl. After acidification and centrifugation the solvent phase was transferred to a test tube preloaded with Na₂SO₄, incubated for 30 min, centrifuged again, and evaporated in vacuum. The residue was mixed with N-methyl-N-trimethylsilyl-trifluoroacetamide (MSTFA) in acetonitrile, and injected into a GC–MS. When analyzing GBL, the salting-out step was omitted, and analysis was performed with a GC–FID apparatus. As revealed by the validation data this procedure is suitable for quantitative determination of GHB and its precursors in blood and/or urine samples.     

International Conference on Harmonisation; Guidance on Q4B Evaluation and Recommendation of Pharmacopoeial Texts for Use in the ICH Regions; Annex on Residue on Ignition/Sulphated Ash General Chapter; Availability. Notice

The Food and Drug Administration (FDA) is announcing the availability of a guidance entitled "Q4B Evaluation and Recommendation of Pharmacopoeial Texts for Use in the ICH Regions; Annex 1: Residue on Ignition/Sulphated Ash General Chapter.' The guidance was prepared under the auspices of the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH). The guidance provides the results of the ICH Q4B evaluation of the Residue on Ignition/Sulphated Ash General Chapter harmonized text from each of the three pharmacopeias (United States, European, and Japanese) represented by the Pharmacopoeial Discussion Group (PDG). The guidance conveys recognition of the three pharmacopeial methods by the three ICH regulatory regions and provides specific information regarding the recognition. The guidance is intended to recognize the interchangeability among these texts from the local regional pharmacopeias, thus avoiding redundant testing in favor of a common testing strategy in each regulatory region. Elsewhere in this issue of the Federal Register, FDA is announcing the availability of a guidance on the Q4B process entitled "Q4B Evaluation and Recommendation of Pharmacopoeial Texts for Use in the ICH Regions."
