基于盾构掘进参数的LVQ神经网络地层识别

以苏州4号线2标及2号线东延伸线5标地铁工程为背景，分析了盾构机的掘进参数：千斤顶推力、推进速度、刀盘扭矩、螺旋机转速和同步注浆量在不同地层条件下的变化规律。提出了基于盾构机掘进参数的学习向量量化（Learning Vector Quantization，LVQ）神经网络地层识别方法。建立了以盾构机五个掘进参数作为输入，地层特性编码为输出的数学模型，通过每种地层100组训练样本对模型进行训练，通过57步训练，训练样本误差控制在0.1以内，并用每种地层50组检验样本进行检验，地层总体识别率达到82.7%。     

后殖民主义视角下的《地之国》解读

约瑟夫·奥尼尔的《地之国》被认为是近年来最出色的表现"9.11事件"后美国的作品之一,但字里行间表现出的后殖民主义特征才是其最引人瞩目之处。小说以回忆录的方式记叙了两个不同肤色、不同阶层的男人在美国的境遇和友谊。本文试图从后殖民主义理论出发,从移民的美国梦想、身份建构和文化认同几个方面阐释作品的深刻内涵,探索众多移民在西方文化中心论依旧盛行的今天,在全球化的时代获得物质和精神双重满足的途径。     

A Pilot Study of 2 Brief Forms of Dialectical Behavior Therapy Skills Training for Emotion Dysregulation in College Students

Abstract

Objective: To examine the feasibility and initial efficacy of 2 abbreviated dialectical behavior therapy (DBT) skills training groups: emotion regulation skills only and emotion regulation with mindfulness skills. Participants: Participants were 24 undergraduates (aged 18–29) with significant emotion dysregulation who participated between February and May of 2010, 2011, and 2012. Methods: Participants participated in 2-hour weekly group sessions for 8 weeks and completed outcome measures at baseline, midtreatment, posttreatment, and 4-week follow-up. Results: Participants in both conditions made significant gains, with large effect sizes, across measures of emotion regulation, affect, skills use, and functioning. There were no differences between the 2 groups, suggesting no additive benefit of mindfulness skills. Conclusions: This pilot study provides support for the acceptability and efficacy of abbreviated DBT skills training in colleges, given significant improvements, positive feedback, and low attrition. Impediments to feasibility included recruitment difficulties, particularly due to scheduling constraints.     

五十年来情绪人类学发展综述——心理人类学发展的趋势

人类学百年发展历程中,始终伴随着对心理学学科理论和实践资源的汲取,随着心理学逐渐对以往科学主义、本质主义的扬弃,将现象学、认知论纳入到学科反思、人类学研究也开辟了注重个体内在化情绪的人类学研究,形成了如今颇受瞩目的情绪人类学领域。阐释学大师格尔兹对于情绪关注的研究,启发后辈学者,心理人类学正越来越多地将情绪作为研究的对象,以揭示他者文化蕴藏的深意。     

论中国历史上的北方民族政权:以辽、西夏、金、元四朝为重点

古代北方民族,常常形成实力强大的集团,对中国历史的全局产生重大影响。在国家政治组织层面上,征服王朝既采纳了一些汉法,又掺入了不少原先政权的制度因素,这样的结合导致了真正的君主专制。女真人政权的合法性得到境内大多数汉族知识阶层人士的认同,蒙古人的元朝则有些逊色。辽、西夏、金、元等王朝非汉族的统治,并没有改变汉地社会、经济、文化的基本面貌,它们的影响主要是政治上的。     

The struggle of autonomy and authenticity: framing the savage refugee

James Hathaway has described refugee law as ‘fundamentally oriented to the promotion of autonomy’. Borrowed from the Kantian roots of liberal rights theory, this theme has come to the fore as refugee advocates decry increasingly draconian experiments in deflection and deterrence. But what exactly does it mean for a refugee to exercise autonomy? And how is it connected to that other popular refrain – that those who arrive irregularly by boat in Australia, despite high recognition rates, are not ‘genuine’ refugees? By examining the assumptions underpinning autonomy as a contemporary political value, and working within the theoretical construct that identifies a state's ‘recognition’ of autonomy with authenticity, this article explores tensions within both public discourse on refugees and the discipline of refugee law itself. It considers how and why the refugee exercising ‘authentic’ moral agency by boarding a boat is depicted not just as a threat, but as inherently irrational (and thus not ‘authentically’ autonomous) and less ‘genuine’ (and thus virtuous) than the ‘passive’ refugee languishing in a camp overseas, awaiting ‘our’ redemptive touch. Finally, it asks whether refugee law similarly suffers from the contradictory moral promise of human rights law which places autonomy at its heart while in practice requiring that humanity be split between victim, savage and redeemer.     

交互认识论：群众路线的新思路

群众路线的认识论是交互认识论,强调了“干-群”双主体之间的对等性、互动性和主体性原则,因而彰显了群众的主体性地位,摒弃了主客体对立的认识论思路,是历史唯物主义在认识论与本体论、辩证法上相一致的表达。通过交互认识,领导与群众形成共同知识与共同信念,在一个不断信息更新、信念修正、信息域和知识域增大的动态过程中,实现领导与群众的利益与责任的一致、手段与目标的一致。     

顾客非理性消费行为机理探析

非理性消费已经成为零售企业利润的重要来源,得到学术界的普遍关注。认为顾客非理性消费行为是受到内在的、最本质的特殊顾客需要驱使而产生的不合理行为,揭示了驱动顾客非理性消费行为的顾客需要,并探讨了情绪状态因素调节顾客需要与顾客非理性消费行为关系的作用机理。基于416份问卷的调查结果,社交需要、释压需要和求廉需要是驱使顾客产生非理性消费行为的主要内在动因,情绪对特殊的顾客需要具有不同的调节作用。旨在丰富顾客非理性消费行为的知识,为商家实施目标营销、新服务开发提供重要理论支持。     

Validation of Nonparametric Two-sample Bootstrap in ROC Analysis on Large Datasets

The nonparametric two-sample bootstrap is applied to computing uncertainties of measures in receiver operating characteristic (ROC) analysis on large datasets in areas such as biometrics, speaker recognition, etc. when the analytical method cannot be used. Its validation was studied by computing the standard errors of the area under ROC curve using the well-established analytical Mann–Whitney statistic method and also using the bootstrap. The analytical result is unique. The bootstrap results are expressed as a probability distribution due to its stochastic nature. The comparisons were carried out using relative errors and hypothesis testing. These match very well. This validation provides a sound foundation for such computations.     

概念、社会与规范性——黑格尔的规范性理论之争

罗尔斯等人对康德的道德哲学做出了建构论的解读,从此将建构论带入到规范性研究中。因为不满康德哲学自身的理论困境,以布兰顿、皮平为代表的社会建构论开始了对黑格尔的规范性研究,将之视为对康德哲学的社会化,把以相互承认为基础的社会视为规范的来源,这一解读方式被称之为“标准解读”。在社会建构论的影响下,斯特恩、莱蒂宁等人分别提出了对黑格尔哲学的规范性解读。一时间,对黑格尔规范性的研究产生了众多丰富的理论成果。考察这一时段理论得失,有助于我们推动黑格尔的规范性研究。
