噪音的文化隐喻

噪音在现代社会中的出现频率越来越高,并因此形成一种有文化意味的现象。文章首先运用词源考证法,考察噪音的最初能指,然后从作家或思想家们对噪音的态度和噪音音乐出发思考了噪音的两种本原意义,进而从《白噪音》、《噪音:音乐的政治经济学》等文本中发掘出噪音的多样文化隐喻。文章最后表明对噪音所具文化隐喻的态度。     

湘西宝卷的类别及特点述略

宝卷是我国民间民俗文献整理的重要史料资源。对宝卷类别考释当下学界诸家或笼统繁复,或交叉重叠。作为湘西民俗的重要载体,湘西宝卷在承继中华宝卷共性的基础上又独具地方特色：（1）从宝卷历史分期看,湘西宝卷历史跨度大,既有“新宝卷时代”之宝卷,还存“古宝卷时代”之最早底本;（2）从民间宗教属性看,湘西宝卷是一种“兼具民间宗教与‘三教合一’”的宝卷,这在其他地区极为罕见;（3）从讲唱程序归类,湘西宝卷目今只存活于当地丧葬与祭祀活动中,这亦乃全国他处宝卷所不备之特质。然由于划分标准非唯一特性,对湘西宝卷类别的研究还有待进一步深入。     

匈奴单于疏证

本文对秦朝、西汉王朝时的匈奴单于,东汉建武二十四年（48年）后分裂附汉的南匈奴单于和留居漠北的北匈奴单于的驻地、承袭、事迹三个方面的问题进行疏理、校订、考证、阐释;着重是对单于的传袭世系和重要事迹两个难以缕析和繁杂纷乱问题的研讨。     

Double-objective economic statistical design of the VP T2 control chart: Wald's identity approach

Research has shown that applying the T² control chart by using a variable parameters (VP) scheme yields rapid detection of out-of-control states. In this paper, the problem of economic statistical design of the VP T²control chart is considered as a double-objective minimization problem with the statistical objective being the adjusted average time to signal and the economic objective being expected cost per hour. We then find the Pareto-optimal designs in which the two objectives are met simultaneously by using a multi-objective genetic algorithm. Through an illustrative example, we show that relatively large benefits can be achieved by applying the VP scheme when compared with usual schemes, and in addition, the multi-objective approach provides the user with designs that are flexible and adaptive.     

小波与相关函数算法在矿山震源定位中的应用

针对矿震震相提取分析中震相信号提取困难、噪声影响大、精度低等问题，提出从小波时频分析和统计学的角度，根据小波域内矿震信号与噪声的不同特性以及不同采集通道间信号具有相关性特点，采用小波阈值滤波算法和相关函数算法对矿震信号进行计算，得到了各个采集通道间较准确的波到时差。试验结果表明，该算法对高斯噪声和其他非相干噪声具有抑制作用，能够有效提高计算结果的精度。     

Exercise and executive functioning in older women

Research suggests that exercise can slow the rate of decline in cognitive functioning in older adults. The effects of aerobic and resistance exercise on executive functioning was examined in 68 women over 50 years of age. Participants completed the Tower of London and Benton Controlled Oral Word Association tests. Findings indicated that individuals participating in both aerobic and resistance exercises performed significantly better than individuals not participating in exercise. Individuals who were participating in both aerobic and resistance exercises did not perform disproportionately better. Thus the form of exercise appears to be less important than engaging in some form of exercise.     

广州：城市博物馆的呼唤

城市博物馆是一座城市的文化之根,历史的记忆与良知,更是未来的基石。凝聚一个国家或民族,需要的是文化的认同以及对未来之保证。博物馆也是这样的认同与保证。打造好它们,需要几代乃至几十代人的精心荟萃。
