论高校图书馆信息咨询服务特点与评价标准

信息咨询服务是图书馆读服务的精髓，它的服务内容和服务质量被看成是衡量整个图书馆服务水平的标尺。随着高校图书馆信息咨询服务内容的不断变化和提升，对信息咨询服务的评价准则和评价指标也应该有一个较为统一的认识。     

BP神经网络模型中活化函数对网络性能影响的研究

本文在ＢＰ神经网络模型中，采用一种新型的神经元活化函数替换传统的Ｓ型活化函数，并在活化函数中引入了可调参量，研究表明，作这一替换后对提高网络的学习速度、抑制假饱和现象起到了很好的作用。

基于身份认同的动机理论及其对大学生学业结果的影响

首先介绍基于身份认同的动机理论。该理论是一种关于人类动机和目标追求的依赖于情境的社会心理学理论, 它认为人们会以一种与某种情境下被启动出来的身份相一致的方式来行为。人们采用某种行为或不采用某种行为, 受到经由环境启动而出现的身份感知的影响。然后, 综述在该理论指导下的相关研究进展情况。最后指出, 未来研究可能需要考虑其他文化背景下的身份类型和不想要的未来身份对大学生学业结果的影响以及某些认知能力与人格因素的调节与中介作用。     

非均匀噪声环境下分布式IVI-CFAR检测算法

为了解决传统分布式VI-CFAR(variability index-constant false alarm rate)和OS-CFAR(order statistic constant false alarm rate)算法在多杂波干扰环境下检测性能严重下降的问题,提出了一种分布式IVI-CFAR(improved VI-CFAR)检测算法。在VI-CFAR的基础上,引入双参考窗和双参量,通过各子参考窗参量与对应门限的比较,判断子参考窗中参考单元的分布情况,从而选择相应的参考单元集和检测器估计背景噪声功率。经过仿真对比,在单杂波和多目标干扰环境下,分布式IVI-CFAR算法检测性能接近于分布式VI-CFAR和OS-CFAR算法;在多杂波干扰环境下,分布式IVI-CFAR算法检测性能优于分布式VI-CFAR和OS-CFAR算法,采用“OR”融合规则时,检测性能最优。结果表明,提出的分布式IVI-CFAR算法在非均匀噪声环境下,均具有较优的检测性能。     

Nonlinear Coherence in Multivariate Research: Invariants and the Reconstruction of Attractors

First, some linear techniques in multivariate time-series analysis in EEG research are reviewed to highlight the problem of estimating the dimensionality of the state space (embedding dimension), the reconstruction of an attractor, and the evaluation of invariant properties of the attractor. The traditional linear techniques included the usual spectral and cospectral measures of power, phase, and coherence to which stepwise discriminant analysis was applied for canonical representation of the attractor. Then, some traditional nonlinear techniques of attractor reconstruction and dimensional analysis which use the time-lagged univariate approach of Ruelle and Takens (Takens, 1981) are reviewed. Next, updates and multivariate generalizations that use singular-value decomposition (Broomhead & King, 1986) are reviewed. Finally, Stewart's (1995, 1996) multivariate generalization of the method of false nearest neighbors (Abarbanel, Brown, Sidorowich, & Tsimring, 1993; Kennel, Brown, & Abarbanel, 1992) is reviewed. These are particularly relevant for evaluating multivariate coherence in research on the complex cooperative dynamical systems found in neuroscience, psychology, and social science when time series of sufficient length are investigated.     

Matrix-assisted laser desorption/ionization-mass spectrometry of cuticular lipid profiles can differentiate sex, age, and mating status of Anopheles gambiae mosquitoes

Malaria is a devastating mosquito-borne disease, which affects hundreds of millions of people each year. It is transmitted predominantly by Anopheles gambiae, whose females must be >10 days old to become infective. In this study, cuticular lipids from a laboratory strain of this mosquito species were analyzed using a mass spectrometry method to evaluate their utility for age, sex and mating status differentiation. Matrix-assisted laser desorption/ionization-mass spectrometry (MALDI-MS), in conjunction with an acenaphthene/silver nitrate matrix preparation, was shown to be 100% effective in classifying A. gambiae females into 1, 7–10, and 14 days of age. MALDI-MS analysis, supported by multivariate statistical methods, was also effective in detecting cuticular lipid differences between the sexes and between virgin and mated females. The technique requires further testing, but the obtained results suggest that MALDI-MS cuticular lipid spectra could be used for age grading of A. gambiae females with precision greater than with other available methods.     

导师义务应当如何设定——以预防研究生学术不端为例

我国立法对导师履行义务与承担责任的构成要件缺乏明晰的规定,在研究生学术不端的预防上尤为突出。由研究生学术不端引发的导师问责既不能适用私法侵权上的过错归责原则,也不能采用结果归责原则。在行为归责上,导师预防研究生学术不端义务的适用面临着标准模糊、监督困难与因果关系缺乏等多重困境。导师在国家立法层面上被赋予的学术伦理教育义务、学术指导义务以及学术不端的事先审核义务,需要接受是否侵害高校办学自主权与教学自由的检验。研究生导师义务的设定应当置于国家、高校与教师的关系视角下进行考察,遵循全面性、弹性与程序性要求,建立“综合考核为主,个案追责为辅”的监督体系,个案追责采用主客观相统一的归责原则。这对当下中国高校研究生导师立德树人职责的落实与研究生教育的改革皆具重要意义。
