论伍尔夫小说《奥兰多——一部传记》中的真理观

<奥兰多--一部传记>是英国现代主义女作家弗吉尼亚·伍尔夫最具想象力的一部作品,雌雄同体和传记式小说是它的标志性特征,然而这并非它的全部研究价值.这部小说承载了作者的真理观.在伍尔夫看来,由于自然和人类自身的问题,生活和世界充满表象的碎片,因此寻求具有永恒性质的、能统一所有表象的真理具有重要的意义.她同时指出,记忆、推断、概括和想象等思维能力是获得真理的手段,作家凭借这些能力进行创作,有理由成为持圭臬者来引领人类社会走向真理.     

Overdispersed negative binomial regression models

Overdispersion is a common phenomenon in actual data sets. It is important to have methods of dealing with extra variation in regression situations. This article develops tests for extra-negative binomial variation and gives some numerical methods to deal with it. Simulations show power comparisons between some of the overdispersion tests discussed. Finally, an example is given to demonstrate the methods.     

克服晕轮效应,做好辅导员工作

随着社会的不断发展,辅导员工作逐步呈现出多样化、复杂化、困难化的趋势。正确地认识、了解、掌握并利用心理效应,在辅导员工作中往往会产生意想不到的效果。晕轮效应是一种普遍的心理错觉,在思想政治教育过程中比较常见,它的负面效应要远远大于正面效应。对于这种负面影响比较大的心理效应,我们要做到首先从理论上了解,继而在实践中避免,这样才能防止落入这些负面效应的恶性怪圈,让辅导员工作达到一个新的高度。     

让历史说话——兰陵辨析

南兰陵兰陵县,就是史书上所载的武进县,兰陵县即武进.兰陵(武进)为齐梁开国者萧道成和萧衍的祖居地,万绥是其故里.文章依据大量历史文献,以历史事实为依据,证明了南兰陵就是武进,武进是萧齐、萧梁的"桑梓本土"、"王业所基",从而否定了"丹阳是南兰陵、兰陵"的说法.     

文学真实的范畴厘定和价值探微

在创作和欣赏实践中 ,“真实”是一个被广泛运用但又偏颇最多的文学价值尺度。“真实”的概念范畴 ,可以从三个角度厘定 :( 1)真实是创造的产物 ;( 2 )真实的创造建基于人类求真向善的合规律性与合目的性之上 ;( 3)真实以文学形象方式具体存在。与真实的主观色彩相反 ,真实的价值奥妙在于它在深层对创作规律的契合 ,以及对生活客体的尊重。因此 ,真实成为文学自然态度、人文精神和作家人格的体现 ,说到底 ,成为文学的胆识、气度和一种可贵的艺术品质     

Reliable Ad Hoc Routing Based on Mobility Prediction

Reliability is a very important issue in Mobile Ad hoc NETworks (MANETs). Shortest paths are usually used to route packets in MANETs. However, a shortest path may fail quickly, because some of the wireless links along a shortest path may be broken shortly after the path is established due to mobility of mobile nodes. Rediscovering routes may result in substantial data loss and message exchange overhead. In this paper, we study reliable ad hoc routing in the urban environment. Specifically, we formulate and study two optimization problems. In the minimum Cost Duration-bounded Path (CDP) routing problem, we seek a minimum cost source to destination path with duration no less than a given threshold. In the maximum Duration Cost-bounded Path (DCP) routing problem, we seek a maximum duration source to destination path with cost no greater than a given threshold. We use a waypoint graph to model the working area of a MANET and present an offline algorithm to compute a duration prediction table for the given waypoint graph. An entry in the duration prediction table contains the guaranteed worst-case duration of the corresponding wireless link. We then present an efficient algorithm which computes a minimum cost duration-bounded path, using the information provided in the duration prediction table. We also present a heuristic algorithm for the DCP routing problem. In addition, we show that the proposed prediction and routing schemes can be easily applied for designing reliable ad hoc routing protocols. Simulation results show that our mobility prediction based routing algorithms lead to higher network throughput and longer average path duration, compared with the shortest path routing.

气浮综合改进设施处理高浓度造纸废水

本文报道了气浮综合改进设施处理高浓度造纸废水的流程和改革，结果表明：改进后的气浮设施COD去除率由60％提高到75％，SS去除率由51％提高到71％，气浮出水河直接回用于造纸的主要过程，处理效果明显优于单纯的气浮处理。而且改进部分投资少，动力消耗少，是处理高浓度造纸废水的简便易行、值得推广的方法。     

可理解性输入、吸收和输出

虽然"可理解性输入"是一个很重要的习得条件,但不是一个充分条件。语言学习者必须将语言输入与语言输出在一个有意义的环境中组合,最大限度地使学习者达到理想的输入(i+1)与输出(i+1),语言习得才能真正有效。     

浅谈玛格丽特·杜拉斯小说的情爱意义

世纪之交,在中国获出全集的殊荣的外国作家是玛格丽特·杜拉斯。对杜拉斯的认识,有很多人或说一般的读者停留在对她小说所谓的"情色"的描写上,为此,有必要对杜拉斯的小说从时代、政治和女人在社会中所处的角色来分析,透过"情"色"看到深刻和严肃的内涵。     

浅说《水浒传》中的蒙汗药

蒙汗药是《水浒传》中的一个物态因子 ,却被作者巧妙地加以运用 ,对引领故事情节的发展 ,塑造人物性格 ,解决矛盾冲突起到了十分重要的作用。作品中关于蒙汗药的大量描写 ,不仅开创了“朴刀”、“杆棒”类小说全新的 "江湖世界 "展现手段 ,而且为后世的武侠小说创作探索出一条新路
