From the Asian Boyz to the Zhu Lian Bang (the Bamboo Union Gang): A Typological Analysis of Delinquent Asian Gangs

Developing a typology for delinquent and criminal gangs has a long history in criminology and criminal justice. Although many typologies have been proposed in the past eight decades, the great majority of these classifications are based on the consideration of one single factor. This approach obviously oversimplifies the nature of gangs and may give gang researchers an impression that gangs of a certain category differ totally from those of another category. The author of this paper argues that differences between gangs are relative, not absolute. To demonstrate this point, a nomenclature on Asian gangs based on the different combinations of the three factors of political belief, organizational layout, and political connection is suggested. According to this nomenclature, Asian gangs can be conceptually categorized as STP, SEP, STN, SEN, ITP, IEP, ITN, and IEN types.

Variation of δ2H, δ18O & δ13C in crude palm oil from different regions in Malaysia: Potential of stable isotope signatures as a key traceability parameter

A total of 33 crude palm oil samples were randomly collected from different regions in Malaysia. Stable carbon isotopic composition (δ¹³C) was determined using Flash 2000 elemental analyzer while hydrogen and oxygen isotopic compositions (δ²H and δ¹⁸O) were analyzed by Thermo Finnigan TC/EA, wherein both instruments were coupled to an isotope ratio mass spectrometer. The bulk δ²H, δ¹⁸O and δ¹³C of the samples were analyzed by Hierarchical Cluster Analysis (HCA), Principal Component Analysis (PCA) and Orthogonal Partial Least Square-Discriminant Analysis (OPLS-DA). Unsupervised HCA and PCA methods have demonstrated that crude palm oil samples were grouped into clusters according to respective state. A predictive model was constructed by supervised OPLS-DA with good predictive power of 52.60%. Robustness of the predictive model was validated with overall accuracy of 71.43%. Blind test samples were correctly assigned to their respective cluster except for samples from southern region. δ¹⁸O was proposed as the promising discriminatory marker for discerning crude palm oil samples obtained from different regions. Stable isotopes profile was proven to be useful for origin traceability of crude palm oil samples at a narrower geographical area, i.e. based on regions in Malaysia. Predictive power and accuracy of the predictive model was expected to improve with the increase in sample size. Conclusively, the results in this study has fulfilled the main objective of this work where the simple approach of combining stable isotope analysis with chemometrics can be used to discriminate crude palm oil samples obtained from different regions in Malaysia. Overall, this study shows the feasibility of this approach to be used as a traceability assessment of crude palm oils.     

当前中国机关事务管理研究中的前沿问题——资产管理、层空关系和集中统一方式

当前我国机关事务管理研究领域仍有诸多前沿问题有待深入研究。在资产管理方面,广义党务机关的资产管理、机构变动情况下的资产管理和土地使用权资产管理是需要着重研究的问题。在不同层次机关和所处空间地域方面,驻地政府参与上级机关的机关事务运行保障、同一空间地域机关事务中通用服务整合、垂直机关的机关事务运行保障、异地办事处机关运行保障以及采取集中办公方式的规划问题是需要着重研究的问题。在机关事务运行保障所采取的集中统一方式中,组织集中统一方式、技术集中统一方式和内部市场交易集中统一方式是不同的方式路径,如何将这些不同的路径应用于不同的发展阶段,构建相应的发展战略,也是需要着重研究的问题。     

Mineralogical and elemental data for soil discriminating and geolocation tracing

One of the key tasks of soil analysis in forensic sciences is to provide information about its diversities and geolocation. In fact, soil analysis is relevant for forensic geologists. In this study, a total of 80 soil samples were collected from eight Chinese cities (10 samples per city). Different minerals and their relative percentages were analyzed by the X-ray diffraction (XRD) method. In addition, the relative amounts of montmorillonite, kaolinite, amphibole, feldspar, calcite, and dolomite provided information about the origin of a soil, either if it came from a northern or southern city of China. The oxide weight percentages of 10 elements of Al₂O₃, SiO_2, Fe₂O₃, K₂O, Na₂O, MgO, CaO, P₂O₅, MnO, and TiO₂ were also obtained by using X-ray fluorescence (XRF) from the 80 soil samples. Moreover, principal component analysis (PCA) and hierarchical clustering analysis (HCA) methods were performed for dimensionality reduction, elemental marker identification and soils classification to the city they came from purposes. The eighty soils analyzed in this study could be tracked correctly to their city of origin. The K-Nearest Neighbors (KNN) model was done to evaluate the prediction ability based on the soil elemental composition, and it was confirmed by cross validation methods. The results demonstrated that mineralogical and elemental composition can provide powerful information for soil discrimination and source tracing.     

从执政效能和执政价值认同看当代大学生的政党认同——基于重庆大学与西南大学的经验材料

本文以重庆大学和西南大学为例,对当代大学生政党认同现状进行调研,研究发现:其一,当代大学生对中国共产党执政效能低度认同,对执政价值中度认同。其二,中国共产党对当代大学生仍然保持较强吸引力,但大学生对执政价值的认同潜藏着不稳定的危机。其三,执政效能认同、执政价值认同都对大学生入党愿望产生正向影响,但执政效能认同的影响力更强。     

Vote as you Think: Determinants of Consistent Decision Making in Direct Democracy

This study investigates the conditions under which Swiss citizens take consistent decisions, that is, decisions that reflect their argument‐based opinions, during direct‐democratic ballots. In line with recent work on cognitive political behavior, we expect the drivers of consistent voting to be found at the individual and contextual level. At the individual level, we argue that political knowledge positively affects consistent decisions. At the contextual level, we anticipate a positive effect for campaign intensity, complexity and negativism. We estimate hierarchical logistic models based on VOX survey data (1999‐2005) and original data that captures the nature of political campaigns. Our results support our expectations for the situational level and (partially) for the individual factors.

In silico toxicity as a tool for harm reduction: A study of new psychoactive amphetamines and cathinones in the context of criminal science

The emergence of new psychoactive substances (NPS) has raised many issues in the context of law enforcement and public drug policies. In this scenario, interdisciplinary studies are crucial to the decision-making process in the field of criminal science. Unfortunately, information about how NPS affect people's health is lacking even though knowledge about the toxic potential of these substances is essential: the more information about these drugs, the greater the possibility of avoiding damage within the scope of a harm reduction policy. Traditional analytical methods may be inaccessible in the field of forensic science because they are relatively expensive and time-consuming. In this sense, less costly and faster in silico methodologies can be useful strategies. In this work, we submitted computer-calculated toxicity values of various amphetamines and cathinones to an unsupervised multivariate analysis, namely Principal Component Analysis (PCA), and to the supervised techniques Soft Independent Modeling of Class Analogy and Partial Least Square-Discriminant Analysis (SIMCA and PLS-DA) to evaluate how these two NPS groups behave. We studied how theoretical and experimental values are correlated by PLS regression. Although experimental data was available for a small amount of molecules, correlation values reproduced literature values. The in silico method efficiently provided information about the drugs. On the basis of our findings, the technical information presented here can be used in decision-making regarding harm reduction policies and help to fulfill the objectives of criminal science.     

代理治理模式：一种统治类型的讨论--以基层政府治理体系为分析单位

代理治理模式揭示基层政府治理的性质,指出基层政府治理体系的核心元素是政治治理而不是科层治理,是党政统合体系与威权治理结构的多重因素作用结果。代理治理模式有三个基本特征：代理治理是政治职能与行政职能的统合体系;代理治理与社会是一种统治关系;代理治理是一种多中心权威治理结构。代理治理模式的权力来源在国家,不在基层社会,向上级政府（国家）负责,与基层社会没有授权关系。代理治理模式的现代转型,应从基层政府的政治职能与行政职能的分离着手,以民主法治原则来建构基层政府的权力结构和治理体系,在行政职能上建构政府治理的公共本质,在政治职能上建构基层治理的社会授权关系。
