Thinking with the Mind,Syncing with the Body: Ballet as Symbolic and Nonsymbolic Interaction

Symbolic interactionist theory describes self‐consciousness as arising through symbolic interaction. I use one empirical case, ballet training, to suggest that symbolic interaction can, by producing self‐consciousness, cultivate unself‐consciousness. Using in‐depth interviews with twenty‐three individuals reporting on training experiences in six countries and twenty‐three American states, I show that dancers can learn, through self‐conscious symbolic interaction, how it feels to embody what an audience sees, as they strive to train their bodies to portray an institutionalized aesthetic. The embodiment of technique facilitates a markedly unself‐conscious “flow” experience while performing. In contrast, having an acute awareness of embodying an incompatible physiology inhibits flow and often motivates dancers to self‐select out of ballet. These interactionist sources of “nonsymbolic” interaction both evoke and suppress “mind” through social interaction.

An Efficient Algorithm for Delay Buffer Minimization

A data flow machine is said to be synchronized if for any vertex u in the underlying data flow graph, all inputs to vertex u arrive at the same time. An unsynchronized data flow machine with an acyclic underlying data flow graph can be transformed into a synchronized system by adding unit delay buffers to the system. This synchronization process can increase pipelining and throughout. Since the addition of delay buffers introduces hardware and area costs, it is desirable to insert the minimum number of delay buffers to synchronize a given data flow machine. Due to important applications in computer design, various delay buffer minimization problems have been studied by many researchers. Several optimal algorithms and heuristic algorithms have been proposed for slightly different models. In this paper, we introduce the concept of extensions of a directed acyclic graph to generalize and formalize several delay buffer minimization problems studied in the literature and present a polynomial time algorithm for computing the minimum delay buffer synchronization of a given data flow machine. Examples are provided to illustrate our algorithm and to show that our algorithm requires fewer delay buffers than previously published optimal algorithms for various models.

中国物流奖与股票超常收益的实证研究

运用事件研究法考察了中国物流奖及奖项类别对公司超常收益的影响。结果发现中国物流奖公告日前5天及当天均无显著的正超常收益,公告日后第1天获得显著的正超常收益。表明获得中国物流奖可为公司带来正超常收益,中国物流奖不存在信息提前泄露现象,股票市场对获得中国物流奖的反应存在滞后效应。奖项类别显著影响超常收益,中国物流百强带来的超常收益最大,中国货代物流百强带来的超常收益最小。     

基于双频超声波多普勒的血流量测量理论模型及仿真

文章提出双频超声波多普勒血流量测量的理论模型,并加以理论证明,在此基础上通过Matlab对其进行仿真,得到双频超声波多普勒血流量测量的理论结果。即两束多普勒信号虽然载波的频率不同,但是经过带通滤波和低通滤波等一系列处理后,两束多普勒频移信号的频谱分布规律没有发生改变。经运算可使多普勒频移信号得到加强,而噪声信号的功率谱得到有效抑制。     

V形空腔内Moffatt涡旋的数值模拟

应用边界元方法 ,对低雷诺数粘性不可压流体在V形空腔内的流动问题进行数值分析 ,数值模拟V形空腔内流体的流场表明 :流场内出现Moffatt涡 ,所形成的两个较大涡旋不但大小不等、强度差别很大而且旋转方向相反 ,其中大涡的涡心坐标为 y1=4 .4cm ,小涡的涡心坐标为 y2 =2 .2cm ,第一个涡的分离点坐标为Y1=4 .8cm ,两涡的分离点坐标为Y2 =2 .4cm ,亦即 :y2 =y1/ 2 ,Y2 =Y1/ 2 ,数值计算结果与Taneda的实验结果比较完全一致。特别是我们还发现V形空腔内不仅仅有两个涡旋 ,而是应有强度急剧减弱的n个涡旋 ,各涡的涡心坐标 yn 以及相邻两涡的分离点坐标Yn 满足如下条件 :yn 1=yn/ 2 ,Yn 1=Yn/ 2。数值计算结果表明在V形空腔内的第四个涡旋的强度已经非常弱 ,其数量级已经是 10 - 4,因此我们有理由认为对θ =2 8.5°的V形空腔有nmax=4。
