毒品公开查缉的程序应用及评测

毒品公开查缉是指执法部门根据查缉毒品的需要,依法采取的以公开方式在边境地区、交通要道、口岸、山间通道、收费站以及飞机场、火车站、长途汽车站、码头、货运物流场所对来往人员、物品、货物、交通工具进行检查、盘查以及现场处置等措施,以期查获毒品、易制毒化学品、毒品原植物、种子及其幼苗的一项专门工作。公开查缉的基本任务是预防、发现、打击毒品违法犯罪活动,将走私渗透入境的毒品堵截查获在辖区内,努力减少毒品内流造成更大的社会危害。同时开展双向查缉,堵截易制毒化学品非法走私外流出境。     

Detection of Gamma-Hydroxybutyric Acid in Various Drink Matrices via AccuTOF-DART*

Abstract: A new screening method for detecting gamma-hydroxybutyric acid (GHB) in drink matrices, using the IonSense, Inc. (Saugus, MA) direct analysis in real time (DART) ion source coupled to a JEOL exact mass time-of-flight mass spectrometer (AccuTOF), was validated and compared with the current screening methodology. The DART ion source allows for analysis of samples under ambient conditions with little to no sample preparation. Fifty drink specimens were spiked at levels of 1, 2, 3, and 4 mg/mL GHB, and analyzed on the AccuTOF-DART. Positive detection of GHB occurred for each of the samples at each concentration level, giving 100% accuracy for the samples tested. Twenty-five of the 50 drink specimens were spiked at 1 mg/mL GHB and tested using a color test known as the GHB Color Test #3. Only two of these 25 specimens tested positive for the presence of GHB, giving only 8% accuracy. Implementation of this new methodology as a screening tool for GHB analysis will quickly eliminate negative specimens allowing the examiner to focus analysis time on those that screened positive.     

浅议刑事申诉的管辖及筛选机制

我国刑事申诉的受理机关是人民检察院和人民法院,但在实践中,这种多头管辖的规定容易造成管辖责任不明、相互推诿,申诉人多门申诉、无人受理的不良结果。因此,我国急需建立一个刑事申诉的筛选机制,并通过这个机制将冤假错案输入到再审系统。国外立法例中的刑事申诉筛选机制有三种类型:司法机关型、独立机构型和民间团体型。比较而言,在我国目前的司法体制下,在权力机关下设申诉案件复查委员会是一个可行的办法。

Drugs in motorists traveling Swedish roads: on-the-road-detection of intoxicated drivers and screening for drugs in these offenders

This paper deals with the police officer's or police doctor's ability to find drivers under the influence of drugs. We have also studied whether the protocol on the driver's previous histories of drug intake is useful for directing the chemist in his analytical approach to revealing intoxicants in the suspects' body fluids. A comprehensive procedure for screening traffic-hazardous drugs in the urine was found necessary and is described. By using this method, we have studied the incidence of drunken drivers with detectable medicinal or illicit agents. The results demonstrate that 91% of those drivers found by the officer or doctor of the police to be on intoxicants other than ethanol, carried some kind of traffic-hazardous drug in their body fluids, and that the doctor was a better judge than the police in identifying these offenders. By using a series of chemical methods for drug screening, we found that every third driver suspected of drunken driving due to ethanol, but not to other intoxicants, held some kind of a traffic-hazardous drug substance in his urine; benzodiazepines and cannabinoids were the most common findings. The data imply that 34% of these suspects revealed their intakes of traffic-dangerous intoxicants. We conclude that the judgements of both the officer and doctor of the police are needed for an efficacious detection of drivers under the influence of drugs. Moreover, the results infer that the chemist has to screen for intoxicants to reveal these in a suspect driver. We also conclude that drugs, particularly the benzodiazepines or cannabinoids, may be commonly encountered in drunken drivers, suspected of being inebriated by ethanol but no other toxicants.     

英语教育的劳动市场回报及英语教育政策调整 —— 基于 2016年问卷调查数据

中国的英语教育近年来受到越来越多的重视。无论是国家还是个人都投入了大量资源用于英语教育,如此巨额的投入所带来的劳动市场回报值得关注。英语教育的劳动市场回报可以分为人力资本投入回报和信号作用回报。研究发现,英语在实际工作中使用越多,工资收入越高,是为英语教育作为人力资本投入回报的证据。但在工作中很少用到英语的人,通过英语四六级考试对其工资也有显著影响,反映了英语教育具有信号作用的功能。调查显示,英语教育的信号作用是英语教育劳动市场回报的主要方面。因此,中国的英语教育有过度教育从而导致资源配置低效率之嫌,建议及时调整国家的英语教育政策。     

Defining Environmental Justice Communities for Regulatory Enforcement: Implications from a Block‐Group‐Level Analysis of New York State

The absence of a clear definition of environmental justice areas has been cited as one of the U.S. Environmental Protection Agency's major deficiencies in managing federal environmental justice programs. Several states have explicitly defined potential environmental justice areas and integrated targeted efforts into the policy‐making process. At the block‐group level, this study evaluates the effects of New York State's environmental justice policy, which defines communities of concern in terms of demographic and socioeconomic characteristics as well as mandates supplemental regulatory enforcement activities for these neighborhoods, on the agency's policy implementation practices under the Clean Air Act and Clean Water Act. The empirical findings suggest that there is inconclusive evidence regarding race/ethnicity‐ and class‐based environmental inequity. Also, the state's policy intervention is not universally effective. Moreover, task environments of a given community are a consistent determinant of the agency's regulatory compliance monitoring and assurance activities. This study then derives broader implications regarding the adoption of a policy instrument that defines and screens potential environmental justice communities.     

Using Gas Chromatography with Ion Mobility Spectrometry to Resolve Explosive Compounds in the Presence of Interferents*

Abstract: Ion mobility spectrometry (IMS) is a valued field detection technology because of its speed and high sensitivity, but IMS cannot easily resolve analytes of interest within mixtures. Coupling gas chromatography (GC) to IMS adds a separation capability to resolve complex matrices. A GC‐IONSCAN^® operated in IMS and GC/IMS modes was evaluated with combinations of five explosives and four interferents. In 100 explosive/interferent combinations, IMS yielded 21 false positives while GC/IMS substantially reduced the occurrence of false positives to one. In addition, the results indicate that through redesign or modification of the preconcentrator there would be significant advantages to using GC/IMS, such as enhancement of the linear dynamic range (LDR) in some situations. By balancing sensitivity with LDR, GC/IMS could prove to be a very advantageous tool when addressing real world complex mixture situations.     

Raman Spectroscopy as a Simple,Rapid, Nondestructive Screening Test for Methamphetamine in Clandestine Laboratory Liquids

Raman spectroscopy has found increased use in the forensic controlled substances laboratory in recent years due to its rapid and nondestructive analysis capabilities. Here, Raman spectroscopy as a screening test for methamphetamine in clandestine laboratory liquid samples is discussed as a way to improve the efficiency of a laboratory by identifying the most probative samples for further workup among multiple samples submitted for analysis. Solutions of methamphetamine in ethanol, diethyl ether, and Coleman fuel were prepared in concentrations ranging from 0.5% to 10% w/v, and Raman spectra of each were collected. A concentration‐dependant Raman peak was observed at 1003 per cm in each solution in 4% w/v and greater solutions. Case samples were analyzed and also found to reliably contain this diagnostic peak when methamphetamine was present. The use of this diagnostic indicator can save the forensic controlled substances laboratory time and materials when analyzing clandestine laboratory liquid submissions.
