有无母亲对青少年自我记忆效应的影响

运用SRE的再认研究范式比较青少年自我参照、母亲参照、偶像参照和他人参照加工任务下的记忆效果。实验一结果表明当学习与测验间隔5分钟时,仅出现自我参照效应,无母亲参照效应和偶像参照效应;实验二结果表明:(1)定向任务的主效应显著(F(3,81)=26.815,p<0.001),母亲状况的主效应边缘显著(F(1,81)=3.375,p>0.05),定向任务和母亲状况的交互作用显著(F(3,81)=15.086,p<0.001);(2)有母亲组被试的自我参照、母亲参照、偶像参照效应显著且两两无差别,三者均与他人参照存在显著差异;(3)无母亲组被试仅存在自我参照效应,并与其他三项加工任务有显著差异。研究证明了在自我参照研究范式中,有无母亲将影响自我是否呈现母亲参照效应。结果提示,在母亲参照效应的研究中,需考虑母亲状况。     

美国私募基金监管法律制度研究及对我国的启示

美国是私募基金最为发达的国家之一。在私募基金发展初期,其对私募基金监管较为宽松。然而,私募基金自身的发展逐渐带来了诸多新问题,如私募股权基金公募化、财务杠杆的大量使用、私募基金私有化上市公司等。2010年,美国通过了《金融监管改革法案》,加强了对私募股权基金的监管。反观我国,私募股权基金在我国已经具有了一定的规模,虽尚不足以产生系统性风险,但有必要从投资者保护角度入手建立健全私募股权基金监管法律制度。     

《阅微草堂笔记》文体辨析

我国传统小说追求真实,而西方小说则要求虚构。《阅微草堂笔记》是传统小说,现在用西方的小说观来衡量、评价它,对它有失公允。应该把我国古代“小说”中符合传统小说观的作品和符合西方小说观的作品加以区分,并给以不同的称谓和不同的评价标准,这才是实事求是的态度。     

提高外文期刊采访质量的策略研究

通过对研究生学位论文引文的统计分析,用文献计量学方法科学地选择定购外文期刊,提高馆藏外 文期刊对读者需求的满足程度,是改进高校图书馆外刊采购质量的有效措施。     

考“睹当”——兼论《汉语大词典》“参见”关联的失误

近代汉语中出现的“睹当”、“堵当”、“覩当”、“赌当”等一组口语词之间存在形音义上的交叉关系,从一定程度上反映了汉语词汇是个立体性的系统。而《汉语大词典》对该组词所作的“参见”关联指引存在失误,不仅未能起到合理建构词汇系统、明确词汇源流演变过程的作用,反使其形音义关系混乱。反映《汉语大词典》“参见”关联指引存在界定模糊、不符合《汉语大词典》编纂方针的问题。     

Reference dependent prices in bargaining: An experimental examination of precise first offers

Evidence from psychology and marketing suggests that those who make a “precise” first offer in bargaining get a better deal than those who make a “round” first offer. We report on a series of experiments designed to test for and improve our understanding of the “precise first offer” (PFO) effect in bargaining and whether it likely reflects rational optimizing or equilibrium behavior. Our experiment varies whether decisions are incentivized and whether the PFO effect can emerge as an equilibrium of a cheap-talk signaling game. We find evidence of a PFO effect when subjects read a vignette and make unincentivized individual decisions. When monetary incentives are added to the vignette, we still find the PFO effect, but it is not robust. In a bilateral bargaining situation with a cheap-talk equilibrium, we can not find the PFO effect, which is inconsistent with the equilibrium predictions. Moreover, the PFO effect reemerges in a setting in which initial offers are generated by a random device and thus provides a strong refutation of the signaling model. Our evidence suggests that optimizing and equilibrium accounts of the PFO effect are inadequate. Understanding initial offers as reference points, which subtly change perceptions about the kinds of acceptable counteroffers, provides a plausible account of a new finding on which prior explanations are silent: precise offers induce more precise counteroffers.     

Bayesian inference for power law processes with applications in repairable systems

Statistical models for recurrent events are of great interest in repairable systems reliability and maintenance. The adopted model under minimal repair maintenance is frequently a nonhomogeneous Poisson process with the power law process (PLP) intensity function. Although inference for the PLP is generally based on maximum likelihood theory, some advantages of the Bayesian approach have been reported in the literature. In this paper it is proposed that the PLP intensity be reparametrized in terms of (β,η), where β is the elasticity of the mean number of events with respect to time and η is the mean number of events for the period in which the system was actually observed. It is shown that β and η are orthogonal and that the likelihood becomes proportional to a product of gamma densities. Therefore, the family of natural conjugate priors is also a product of gammas. The idea is extended to the case that several realizations of the same PLP are observed along overlapping periods of time. Some Monte Carlo simulations are provided to study the frequentist behavior of the Bayesian estimates and to compare them with the maximum likelihood estimates. The results are applied to a real problem concerning the determination of the optimal periodicity of preventive maintenance for a set of power transformers. Prior distributions are elicited for β and η based on their operational interpretation and engineering expertise.     

多丽丝·莱辛《十九号房》中苏珊的悲剧分析

多丽丝·莱辛《十九号房》中女主人公苏珊的悲剧是由最初的分工不公直接导致的,而根本原因则在于传统男权观念的影响。作者通过对苏珊悲剧命运的详细描绘揭示了一种带有普遍性的生存状况,并进而启发读者思考：作为一个生活在男权传统之下的女性该如何保持自我。     

LMS方法及其在流量数据中的应用

LMS模型是分析生长发育最常用的方法之一。本文详细阐述了LMS模型的构造原理；基于流量数据提出了费希尔信息矩阵与惩罚贝叶斯后验对数似然算法两种模型算法；利用中国健康营养调查（CHNS）1989-2011年中9年的流量数据，以所提出的LMS曲线算法为基础，通过计算BMI（Body Mass Index）绘制生长发育曲线研究我国青少年儿童生长发育情况和中年人健康问题。研究结果表明：1989-2011年间，我国0~18岁年龄段青少年儿童BMI中位数提高5%左右，生长发育高峰期有提前趋势；中年人群BMI中位数提高了10%左右，2000年后55周岁以上中年人体质差异有增大趋势。
