Composite Machine Learning Algorithm for Material Sourcing,

This study developed a composite machine learning algorithm for attribution of materials of forensic interest (like ammonium nitrate) to original sources. k-nearest neighbor and random forest models were used for source elimination and classification, respectively, in a two-step, composite algorithm based on particle color, size/shape, and trace element concentration features. Novel approaches for simulation to supplement within-source reference features based on empirically measured multi-lot analyses, an improved hold-one-lot-out method for cross-validation, an assessment of the likelihood of the presence of a reference sample, fusion of the source probabilities from the respective classification models, and the calculation of metrics for assessing ensemble sourcing performance are described. Excellent sourcing predictions were obtained; the sourcing algorithm identified the correct source as the top choice 89% of the time, and the correct source was identified to be an average of 2.7 times more likely than the most likely incorrect source.     

Managing commercial risks in open source software licensing

Legal context: The article reviews the commercial risk allocation clauses intypical open source licence terms and discusses their enforceabilityand implications. Key points: The enforceability of warranty disclaimers and limitation ofliability clauses in common open source licence terms is questionable,particularly in a cross-border context, and commercial licensorsshould take additional steps to protect themselves from down-streamrisks. Practical significance: Open source software presents a number of unusual commercialissues, because it is available free of charge and the providerstry to disclaim warranties and liabilities. End users and resellershave to adjust their own in- and out-licensing models to accommodatethis situation.     

价值视角的转变与正义模式的演绎——评美国1998年《ADR 法》

经过联邦法院对 ADR 的十几年的探索实验,美国国会最终通过了1998年《ADR 法》,为 ADR 措施的开展发放了“绿卡”。该法要求所有的美国联邦法院实施“当事人服务型”的 ADR 措施,并允许法院强制当事人参加 ADR 程序。联邦法院 ADR 部门要想成功有效的实施该法,对各种 ADR 措施进行选择,以使其与现有的法院体系相兼容,同时为当事人提供便利,首先要协调好 ADR 措施所内涵的正义模式与一直引导着法院的传统的判决型的正义模式的关系。

哈巴罗夫斯克边疆区旅游业的特点在于出入境旅游和国内旅游同步发展。优越的地理环境为其面向中国、日本和韩国等相邻国家发展入境游创造了良好的条件，也为其发展地区旅游经济打下了坚实的基础。     

犯罪源头-未成年人犯罪

当前,未成年人犯罪逐年增多,危害日益严重,且呈现出新的动向与特点.而未成年人犯罪是犯罪的源头,要遏制犯罪,必须分析未成年人犯罪的原因,从源头抓起,预防、治理青少年犯罪中的未成年人犯罪.     

基于资源的公司权力配置研究

随着公司治理问题研究的不断深入,处于公司治理中心的权力配置问题成为研究的热点。以公司所拥有的资源为视角,可将参与公司权力配置的资源分为硬资源和软资源这两类。在对影响权力配置的产权状况、资源结构和性质、资源的集中度等关键因素分析的基础上,按照公司价值创造的逻辑,公司权力(决策权、执行权和监督权)可基本分为一元主导、二元分享和多元共享这三类配置模式。这一研究对公司治理理论和管理实践具有重要的指导意义。     

法制统一维护制度之检视与完善

法制统一的维护不力需要进行制度上的反思。法制统一制度在主体配置、权限分工以及维护机制等方面均存在诸多问题和缺陷,因此需要优化配置法制统一的维护主体,合理分工维护权限,健全完善维护机制,从而完善法制统一维护制度。     

影响农民增收的制度因素浅析

农民收入增长缓慢已成为当前农村发展的突出矛盾。农民能否增收与国家支持农业的政策和有关制度有着深层次的联系,政策和制度强烈地影响着农民的经济命运和社会地位。农民增收应改革户籍制度对农民社会地位的隐性限制;农民增收要消除乡村组织制度对农民利益的损益剥夺;农民增收应对的县乡组织制度创新要树立小政府大服务的理念。     

巨额财产来源不明罪量刑畸轻的危害

巨额财产来源不明罪的设立 ,对打击犯罪曾经起过积极作用。但随着经济的发展和时间的推移 ,腐败分子巨额财产来源不明的现象却屡禁不止、愈演愈烈 ,重要原因之一是由于刑法规定的该罪的量刑幅度畸轻。这不仅违背了罪刑相适应的原则 ,放纵了犯罪 ,而且为执法者徇私枉法开了方便之门。建议立法机构比照贪污、受贿罪的量刑进行修改 ,提高法定刑、增加量刑档次。     

Gender diversity in aircraft maintenance: a cross-sectional triangulation of male perspectives

Certified aircraft mechanics represent the largest gender-based demographic disparity in aviation with a 49-to-1 male-to-female ratio. Recent research into women’s perspective on the aircraft mechanic career field revealed that a large majority of women felt unsure or negatively about their potential promotion opportunities and social acceptance. The purpose of this follow-on mixed-methods concurrent triangulation study was to explore the perspectives of men regarding the aforementioned topics to see if they differ from previously published research on women perceptions. A total of 587 men and 431 women completed an eight-question survey containing 5-point Likert-type and open-ended questions. The quantitative comparison consisted of the total 1018 responses, while only the survey responses from the 587 men were analysed for correlations and qualitative codes. Results indicated that there was a significant difference between the perceptions of men from those of the women regarding work environment safety and social acceptance. Additional correlation analysis revealed social acceptance to be a key variable when predicting career appropriateness, advancement opportunity and work environment safety. The 587 qualitative responses yielded results that differed from those of women, citing an assumption that women have the same advancement opportunities or be as socially accepted as men entering the field.
