《阅微草堂笔记》中的法理人情

清代纪昀的《阅微草堂笔记》以其独特的话语方式用相当的篇幅讲述涉法故事,从直接宣传、借助鬼神信仰、与礼教相提并论三个方面宣传当时律例。其法律思想的特征为紧密结合儒家伦理精神,重视人情人欲,与传统的道德教化取向一致。     

行政许可法实施中的困境

尽管社会各界对《行政许可法》的制定与颁布曾经反响空前、赞誉颇多,但是,该部法律实施1年多来的实践说明,由于观念和体制惯性的影响、实施前清理的不彻底、立法技术本身的不足,以及监督与其他配套制度的不健全等方面的原因,使得其实施的实际效果与人们的事前期待并不匹配。

A Study of the Background Levels of Male DNA on Underpants Worn by Females

This study is the first to examine the background level of male DNA on underpants worn by females in the absence of sexual contact. Here, we examined 103 samples from the inside front of underpants from 85 female volunteers. Samples were examined for the presence of male DNA using NGM SElect and PowerPlex Y23 kits. Only five samples gave a “complete” Y-STR profile, even though 83.5% of our volunteers cohabited with a male. In all cases where a partner reference sample was available, the Y-STR profile matched the cohabiting partner. We have demonstrated that a Y-STR profile is not expected on the inside front of underpants worn by females after social contact alone. The results of this study are informative for evaluating the significance of a Y-STR profile on underpants in cases of alleged sexual assault.     

Single Nucleotide Polymorphism Assay for Genetic Identification of Lophophora williamsii*

Lophophora is a member of the Cactaceae family, which contains two species: Lophophora williamsii and L. diffusa. Lophophora williamsii is an illegal plant containing mescaline, a hallucinogenic alkaloid. In this study, a novel method based on a single nucleotide polymorphism (SNP) assay was developed for identifying L. williamsii; this assay reliably detects SNPs within chloroplast DNA (rbcL, matK, and trnL-trnF IGS) and was validated for identifying Lophophora and L. williamsii simultaneously. The chloroplast DNA sequences from four L. williamsii and three L. diffusa plants were obtained and compared using DNA sequence data from approximately 300 other Cactaceae species available in GenBank. From this sequence data, a total of seven SNPs were determined to be suitable for identifying L. williamsii. A multiplex assay was constructed using the ABI PRISM^® SNaPshot™ Multiplex Kit (Applied Biosystems, Forster City, CA) to analyze species-specific SNPs. Using this multiplex assay, we clearly distinguished the Lophophora among 19 species in the Cactaceae family. Additionally, L. williamsii was distinguished from L. diffusa. These results suggest that the newly developed assay may help resolve crimes related to illegal distribution and use. This multiplex assay will be useful for the genetic identification of L. williamsii and can complement conventional methods of detecting mescaline.     

Reassembling Linux-based Hybrid RAID

Network-attached storage (NAS) is a system that uses a redundant array of disks (RAID) to create virtual disks comprising multiple disks and provide network services such as FTP, SSH, and WebDAV. Using these services, the NAS's virtual disks store data about individuals or groups, making them a critical analysis target for digital forensics. Well-known storage manufacturers like Seagate, Synology, and NETGEAR use Linux-based software RAID, and they usually support Berkeley RAID (e.g., RAID 0, 1, 5, 6, and 10) as well as self-developed hybrid RAID. Those manufacturers have published data on the introduction and features of hybrid RAID, but there is not enough information to reassemble RAID from a digital forensic perspective. Besides, digital forensic tools (such as EnCase, FTK, X-ways, and RAID Reconstructor) do not support automatic RAID reassembly for hybrid RAID, so research on hybrid RAID reassembly methods is necessary. This paper analyzes the disk array composed of hybrid RAID and explains the layout of disk array, partition layout in hybrid RAID, and hybrid RAID configuration strategy. Furthermore, it suggests parameters that are required for RAID reassembly and then propose a hybrid RAID reassembly procedure using them. Finally, we propose a proof-of-concept tool (Hybrid RAID Reconstructor) that identifies hybrid RAID from disk array and parse RAID parameters.     

Explicating Acculturation Strategies among Asian American Youth: Subtypes and Correlates across Filipino and Korean Americans

Acculturation strategy, a varying combination of heritage and mainstream cultural orientations and one of the significant determinants of youth development, has been understudied with Asian American youth and particularly at a subgroup-specific level. This study used person-oriented latent profile analysis (LPA) to identify acculturation strategy subtypes among Filipino American and Korean American adolescents living in the Midwest. Associations between the subtypes and numerous correlates including demographics, family process and youth outcomes were also examined. Using large scale survey data (N?=?1580; 379 Filipino American youth and 377 parents, and 410 Korean American youth and 414 parents; M_AGE of youth?=?15.01), the study found three acculturation subtypes for Filipino American youth: High Assimilation with Ethnic Identity, Integrated Bicultural with Strongest Ethnic Identity, and Modest Bicultural with Strong Ethnic Identity; and three acculturation subtypes for Korean American youth: Separation, Integrated Bicultural, and Modest Bicultural with Strong Ethnic Identity. Both Filipino American and Korean American youth exhibited immersion in the host culture while retaining a strong heritage identity. Although bicultural strategies appear most favorable, the results varied by gender and ethnicity, e.g., integrated bicultural Filipino Americans, comprised of more girls, might do well at school but were at risk of poor mental health. Korean American separation, comprised of more boys, demonstrated a small but significant risk in family process and substance use behaviors that merits in-depth examination. The findings deepen the understanding of heterogeneous acculturation strategies among Asian American youth and provide implications for future research.     

超大型城市社会精细化治理现状分析与顶层设计——以上海市为例

城市治理问题的复杂性决定了治理模式的多样性,深入理解、系统把握超大型城市社会精细化治理的时代特征和内涵特点,探索基于现代信息技术的治理范式与机制路径,成为具有重要理论意义的实践课题。当前,上海市社会精细化治理成效明显,但仍存在顶层设计不足、数据平台分散、推进不均衡、感知度满意度较低等问题,其原因在于精细化理念和文化缺失的思想困境、缺位错位越位的治理主体困境、法制与监督不精密的制度困境,以及失衡与薄弱的技术手段困境。上海推进社会精细化治理,要按照“物联、数联、智联”三位一体原则,构建“线上线下融合、上下双向互动、流程驱动、科学决策、过程控制、法治保障”的社会精细化治理新模式,形成“两案三制一体”的治理体系。进一步,要更加注重人本主义,更加重视基层自治,更加关注多元主体诉求,更加彰显文化力量,充分运用现代科技,强化社会治理精细化本体建设和载体依托,优化超大型城市社会精细化治理流程和机制。
