从三个环节着力推进党的十九大精神在高校的传播---以斯图亚特·霍尔的编码解码理论为研究视域

党的十九大精神是实现中华民族复兴梦的思想引领,也是指导中国特色社会主义事业向前推进的行动指南.着力推进党的十九大精神在高校的传播,既是"新时代"中国高校的首要政治任务与工作要求,同时也是推进十九大精神向全社会传播的重要环节.斯图亚特·霍尔建构的编码解码理论是适用于一切话语生产分析的理论范式,与十九大精神在高校的传播工作有着深刻的内在契合.它启示我们,要想推进党的十九大精神在高校传播工作的顺利进行,要夯实基础,注重理论建构环节;要优化路径,重视理论传递过程;要关注受众,重视理论的解码过程.

水声目标机动检测与跟踪

当今海战场水声目标往往采用机动方式航行,打破了目标匀速直线运动假定的传统。通过对水声目标的机动模式分析,可将目标的运动轨迹近似为折线运动进行研究。提出了水声目标的机动检测与跟踪方法,简化机动检测的复杂度,最后讨论了对机动目标长时跟踪的策略。     

Terminal allocation problem in a transshipment hub considering bunker consumption

This article investigates the method of allocating arriving vessels to the terminals in transshipment hubs. The terminal allocation decision faced by a shipping alliance has the influence on the scheduled arrival time of vessels and further affects the bunker consumption cost for the vessels. A model is formulated to minimize the bunker consumption cost as well as the transportation cost of inter‐terminal transshipment flows/movements. The capacity limitation of the port resources such as quay cranes (QCs) and berths is taken into account. Besides the terminal allocation, the QC assignment decision is also incorporated in the proposed model. A local branching based method and a particle swarm optimization based method are developed to solve the model in large‐scale problem instances. Numerical experiments are also conducted to validate the effectiveness of the proposed model, which can save around 14% of the cost when compared with the “First Come First Served” decision rule. Moreover, the proposed solution methods not only solve the proposed model within a reasonable computation time, but also obtain near‐optimal results with about 0.1～0.7% relative gap. © 2016 Wiley Periodicals, Inc.

Economic screening procedures in logistic and normal models

Economic screening procedures based on a continuous screening variable X in place of a dichotomous performance variable T are presented. Optimal critical values on the screening variable minimizing the expected cost are obtained for two models; it is assumed that X given T is normally distributed in normal model and P[T = 1|X] is a logistic function of X in the logistic model, and that costs are incurred by screening inspection and misclassification errors. Cases where some parameters are unknown are also considered.
