二进制改进粒子群算法在背包问题中的应用

提出了用于求解0 1背包问题的二进制编码的粒子群算法,阐明了该算法求解背包问题的具体实现过程.为了提高粒子群算法的收敛速度,在传统的二进制编码的粒子群算法中嵌入了记忆功能.通过对其他文献中仿真实例的计算和结果比较,表明该算法在寻优能力、计算速度和稳定性方面都超过了文献中提到的遗传算法和模拟退火算法.提出的求解背包问题的二进制改进粒子群算法,同样可以应用于其他离散优化问题.     

《诗经》所载典礼仪式乐章考论

《诗经》中的典礼仪式乐歌 ,一指祭祖仪式乐歌 ,二指应用于燕乐、乡乐、大射诸礼中的乐歌。本文依据出土文献与传世文献对诸种乐歌形态做了细致的分析 ,认为《诗经》的编排明显受到典礼仪式的影响 ,诗乐礼有先后之别而统一于仪式之中 ,典礼仪式具有宗教、伦理和艺术表现诸种功能

Placing Clinical Social Workers “Between a Legal Rock and a Practice Hard Place”: Reactions to Madden and Parody

The debate about the veracity of incest memories uncovered in therapy is often impassioned and acrimonious. Recent statements by various professional organizations, advising that corroboration of recovered memories is the only method for determining their accuracy, have not decreased the intensity of this debate. This response to Madden and Parody's paper discusses the importance of corroboration of recovered memories of sexual abuse and details the clinical, scientific, and legal foundations for this approach. A point of confusion in Madden and Parody's paper and an important aspect of this response is the difference between clients who uncover completely new memories of childhood sexual abuse and clients who enter therapy with a history of sexual abuse. Those clients with new memories are the focus of this debate and the standard of care proposed in this paper.     

Change-of-variance problem for linear processes with long memory

In this paper we investigate the asymptotic properties of the test statistics for detecting change-points in the variance of infinite moving average sequences with long memory. This research is partly supported by NSFC Grants and SRF for ROCS, SEM.

Temporal Aggregation of Stationary and Non-stationary Continuous-Time Processes

Abstract.  We study the autocorrelation structure of aggregates from a continuous-time process. The underlying continuous-time process or some of its higher derivative is assumed to be a stationary continuous-time auto-regressive fractionally integrated moving-average (CARFIMA) process with Hurst parameter H . We derive closed-form expressions for the limiting autocorrelation function and the normalized spectral density of the aggregates, as the extent of aggregation increases to infinity. The limiting model of the aggregates, after appropriate number of differencing, is shown to be some functional of the standard fractional Brownian motion with the same Hurst parameter of the continuous-time process from which the aggregates are measured. These results are then used to assess the loss of forecasting efficiency due to aggregation.     

战争人生的心灵体验

对于民族记忆而言,战时中国文学留摄下的心灵体验、生命体悟,包含了一个民族对于自身遭受到的侵略战争的全部回答。无论是战争初期"放逐"、漂泊中"远行者"等形象的塑造,还是战争相持阶段的"怀旧",都表明作家们的感悟超越着战事,而寄寓着对民族长远建设、根本命运的思考。而战时中国文学暴露讽刺的多元形态、哲思的不同取向,也都表明作家的战争人生体悟从民族战争本位向战争本位的转化,呈现出超越具体战争对峙,求索于人类自救和民族自立的内在层面。正是这些战争人生的心灵体验,构成了战时中国文学的博大、独异。

基于潜在语义分析的长时工作记忆 在语篇理解中的作用

短时工作记忆与长时工作记忆的区别在于,短时工作记忆的容纳、接受能力是有限的 ;而长时工作记忆是专家可在其专业研究范围内得到的一个相对稳定的系统。语篇理解可视 为一种专业化的技能,其过程是读者根据文字材料描写的内容以及自己所具备的知识,建立 对阅读内容的心理表征的过程。分析长时工作记忆在语篇理解中的作用是指在理解期间注重 相关知识的灵活运用,并能快速、准确地进行信息提取和存储。在语篇理解中,潜在语义分 析(latent semantic analysis,缩写为LSA)是通过分析词与词之间,词与段以及段与段之 间的关系来激活分析者已有的知识的一种关于知识表征的理论。
