Evolution of the content of THC and other major cannabinoids in drug-type cannabis cuttings and seedlings during growth of plants

In Europe, authorities frequently ask forensic laboratories to analyze seized cannabis plants to prove that cultivation was illegal (drug type and not fiber type). This is generally done with mature and flowering plants. However, authorities are often confronted with very young specimens. The aim of our study was to evaluate when the chemotype of cannabis plantlets can be surely determined through analysis of eight major cannabinoids content during growth. Drug-type seedlings and cuttings were cultivated, sampled each week, and analyzed by high-performance liquid chromatography with diode array detection. The chemotype of clones was recognizable at any developmental stage because of high total Δ(9)-tetrahydrocannabinol (THC) concentrations even at the start of the cultivation. Conversely, right after germination seedlings contained a low total THC content, but it increased quickly with plant age up, allowing chemotype determination after 3 weeks. In conclusion, it is not necessary to wait for plants' flowering to identify drug-type cannabis generally cultivated in Europe.     

DIFFERENTIAL SUSCEPTIBILITY? IMMIGRANT YOUTH AND PEER INFLUENCE*

There is reason to suspect that lower levels of exposure to criminogenic peer‐based risks help explain why immigrant youth are less involved in crime and violence. However, it also is possible that if and when they do encounter these risks, immigrant youth are more vulnerable to them than are native‐born youth. Drawing from literature on the adaptation experiences of immigrant adolescents, we hypothesize that immigrant youth will be relatively more susceptible to the effects of both 1) exposure to deviant peers and 2) unstructured and unsupervised socializing with peers when compared with their nonimmigrant counterparts. Using a sample of approximately 1,800 adolescents from the Project on Human Development in Chicago Neighborhoods (PHDCN) study, we find support for our first hypothesis but not the second. Specifically, in both cross‐sectional and longitudinal models, we find that exposure to deviant peers has a greater impact on violence among immigrant youth than it does for native‐born youth. Furthermore, this pattern of results is supported with supplemental, sensitivity analysis using the AddHealth data. In contrast, there are no statistically significant differences across immigrant generation status with regard to the effect of informal socializing with peers on violence.     

Multiple stable isotope characterization as a forensic tool to distinguish acid scavenger samples

Acid scavengers are frequently used as stabilizer compounds in a variety of applications. When used to stabilize volatile compounds such as nerve agents, the lower volatility and higher stability of acid scavengers make them more persistent in a post-event forensic setting. Compound-specific isotope analysis of carbon, nitrogen, and hydrogen in three acid-scavenging compounds (N,N-diethylaniline, tributylamine, and triethylamine) were used as a tool for distinguishing between different samples. Combined analysis of multiple isotopes improved sample resolution, for instance differentiation between triethylamine samples improved from 80% based on carbon alone to 96% when combining with additional isotope data. The compound-specific methods developed here can be applied to instances where these compounds are not pure, such as when mixed with an agent or when found as a residue. Effective sample matching can be crucial for linking compounds at multiple event sites or linking a supply inventory to an event.     

Good Faith,Flawed Assets and the Emasculation of the UK Anti‐Deprivation Rule

The Supreme Court's unanimous decision in Belmont Park Investments Pty Ltd v BNY Corporate Trustee Services Ltd and Lehman Brothers Special Financing Inc is of major significance to lenders, especially those in the global structured finance market. This case confirms the validity of commonly used insolvency‐triggered secured‐priority flip clauses, and, more generally, suggests a dramatically reduced role for the common law anti‐deprivation principle. The decision may not fully resolve market uncertainty, however, given the particular analysis adopted in the case itself (analysed here) and its divergence from the US statutory approach to the same principle.     

行政法上请求权的体系及功能研究

行政法上的请求权源自于公权利,请求权作为公权利的一种类型,其权能覆盖整个公权利。行政法上的请求权可以分为原权型请求权和救济型请求权。原权型请求权包括给付请求权、行政合同上请求权、公法上无因管理请求权、公法上不当得利请求权、无瑕疵裁量请求权和行政程序参加请求权,救济型请求权包括防御请求权、损害填补请求权和确认请求权。各种请求权之间存在着逻辑关系,从而形成了对公民的严密保护。请求权将行政法与行政诉讼法联结起来,对于确定行政诉讼的原告资格、判决类型以及行政法规范的体系化具有重要作用。     

从所有权法向物权法的转型——以“《俄罗斯联邦民法典》完善计划”为向度

自"前苏联解体"20多年以来,俄罗斯物权立法逐渐摆脱计划经济时代的物权观念,不断地向着传统物权法的类型与体系回归。通过渐次的多级转换,俄罗斯物权立法从"所有权中心主义的物权立法"向"他物权日益凸显的物权立法"转化。近年来通过"《俄罗斯联邦民法典》完善计划"的实施使之具有了与大陆法系之德国法传统的物权法相类似的体系特征。     

信用本质:经济要求权的实现——基于全球金融危机的反思

肇端于2007年初的美国次级抵押房贷危机以难以预料的方式迅速、广泛、深刻地影响整个世界的经济、政治、以至思想。金融衍生产品的极度扩张与发展,不仅使监管者、中介机构和投资者都陷入风险定价迷失之中,更因为在危机链条环节,不断创造出来的金融衍生产品将法律关系中的信用主体模糊,使得虚拟经济条件下的信用比照实体经济中信用构成要素发生很大变化。传统的信用学说并没有将股权与信用相联系,而在现代经济社会中,资本市场的重要性及其信用问题使股权与信用关系极为密切。随着现代信息技术的发展,知识已经成为资本、生产要素的组成部分,"敏捷制造"等新型的生产方式使得传统的价值链构成发生了重大变革,将知识产权纳入信用的研究范围探讨并揭示经济社会信用本质具有重要意义。     

我国农村土地家庭承包经营权的权利主体探究

家庭承包是农村土地承包经营中非常重要的一种方式,家庭承包经营权的权利主体是集体经济组织成员还是农户直接影响到了该权利的利益归属以及存续过程中的权利变更。结合我国农村历史发展状况和现行法律的立法目的,应该明确家庭承包经营权的实质权利主体应为集体经济组织成员,该权利具有成员权的属性,是农村集体经济组织成员人人平等享有的权利,农户只是家庭承包中的形式主体。     

公法不当得利及其救济

随着给付行政的兴起,公法实践中出现了因欠缺法律原因而发生的财产变动。在适用民法不当得利制度无法解决的情况下,基于依法行政以及财产权保护的需要,应确立公法不当得利制度。在公法不当得利中,行政主体和行政相对人均可享有公法不当得利返还请求权,而此种请求权则可以通过做出行政行为以及提起行政给付诉讼的形式加以救济。     

死刑案件被害人权利保护问题

在刑事司法领域,人权保障是一个内涵丰富且不断发展的制度体系。既要保障犯罪嫌疑人、被告人的合法权利,也要保障被害人的合法权利,同时注意二者平衡。1996年《刑事诉讼法》确认了被害人的诉讼主体地位,但由于缺少配套机制,导致实践中出现诸多问题。新《刑事诉讼法》在很大程度上完善了犯罪嫌疑人、被告人的诉讼权利及其保护,但较少涉及被害人的权利保护问题。与普通刑事案件相比,死刑案件给被害人造成的伤害尤为严重,应当给予特别保护。
