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.     

高职高专英语教学改革亟待解决的问题

随着经济全球化进程的加快，我国高职高专英语教学改革已迫在眉睫。然而，高职高专英语教学改革又是一项系统工程，涉及教学工作的方方面面，需要从上到下共同不懈的努力。教学目标定位不合适，教学手段不现代化，教学管理不到位，师资队伍问题不解决，高职高专英语教学改革这壶温水一时还难烧开。     

对法律事实建构论的初步阐释——以主体间性为分析进路的思考

诉讼法学界关于客观真实与法律真实的争论是针对法律事实的认定标准所产生的分歧,但是,争论并没有跳出主观与客观、事实与价值、形式与实质这种二元对立的思维模式。而要探究法律事实的形成,必须重新考察诉讼活动的性质,进而实现分析进路由主体性向主体间性的转换。法律事实建构论的提出就是这种分析进路转换之后的结果,但值得注意的是,我们必须对法律事实建构论的限度保持必要的警醒。     

国际海运立法中分化与协调的百年变奏——以海上货物运输承运人责任制度为视角

承运人责任制度是国际海上货物运输法律制度的核心,其发生、发展与变革无不取决于国际贸易、航海技术、运输方式等因素.基于此,我们认为:在未来的一个相当长的时期内,过失责任制应该得到维系,在过失责任制下,免责事项将逐渐醇化,举证责任将根据航运实践的特点予以合理分配,承运人的赔偿责任亦将继续得到适当的限制,从而使过失责任制得到彻底的贯彻.     

Coping with an unjust fate: The case of structural unemployment

Becoming a victim of structural unemployment means suffering an unjust fate. The present research examines the cognitive reactions subjects use to protect their belief in a just world and the related effects on their actual well-being within a sample of unemployed blue-collar workers in East Germany (all female). Results showed that the belief in a just world was positively correlated with attributing one’s unemployment to one’s own behavior and negatively with asking “why me?”, but uncorrelated with subjects’ readiness to change into another profession in order to get employed. Just world belief and depression were negatively related for those who either avoided the “why me?” question or who found an answer to it; but just world belief and depression was positively related for those women ruminating about an unanswered “why me?”. Results are consistent with the idea that the belief in a just world plays a significant role in the unemployed person’s coping process.     

医疗事故罪客观要件探析

认定医疗事故罪,在客观上首先必须存在合法的医疗行为。其次必须在合法的医疗过程中出现严重不负责任的行为。认定严重不负责任,应当主要结合医务人员的注意义务,把违反常规性、常识性的注意义务,以及常发性的过失行为认定为严重不负责任。再次,严重损害就诊人身体健康应当根据《刑法》所规定的重伤标准去判断。最后,严重不负责任是就诊人死亡或严重损害就诊人身体健康的后果的主要原因力。     

有限责任公司法律制度的改革

有限责任公司具有资合性、人合性与封闭性;有限责任公司制度的改革应坚持适应性和引导性两大目标,任何有限责任公司法的改革都不是在消灭实质意义的有限责任公司,在不同的国情下,可能有限责任公司的名字在变化,而它固有的特性则越改革越凸现出来。     

公共决策中的理性:价值问题研究

本文尝试对公共决策过程中的理性,尤其是工具理性的含义、内容及其与价值的关系进行探讨,并提出理性面对不同层面的价值时有不同的反应、诉求和精神体现。工具理性在对待价值问题时所暴露出来的局限是其自身无法克服的,而且也给决策实践带来了诸多问题。

关于制定行政程序法典若干问题的思考

我国亟需制定一部行政程序法典,对行政权力的运行加以程序规制,防止权利滥用,增强行政相对人的民主参与。 制定行政程序法典的目标模式应当是以公正为主、效率为辅的法典,立法模式应当是实体程序合一型、类别型、复合型的行 政程序法典。
