论终身教育趋势下军校教师学习的终身化

学习,是人类认识自然和社会、不断完善和发展自我的必由之路。终身学习是21世纪的生存概念,是教师自身发展和适应职业的必由之路。教师专业发展是一个随时代变迁永无止境的过程。在终身教育趋势下,军校教师要不断提高自己,树立终身学习观念。     

苏共思想教育工作失策对我军的启示

苏联剧变,有其多方面的原因。就意识形态来说,苏共思想教育工作的失策,导致全社会尤其是青年一代从意识形态迷茫,滑落到理想信念崩溃,无疑是政变的思想根源。分析苏共思想教育工作的经验教训,以便创新和改进我军思想政治教育的内容、形式和手段,促进思想政治教育工作的有效开展。     

Modeling and analysis of a mixed‐model assembly line with stochastic operation times

We consider a mixed‐model assembly line (MMAL) comprised a set of workstations and a conveyor. The workstations are arranged in a serial configuration. The conveyor moves at a constant speed along the workstations. Initial units belonging to different models are successively fed onto the conveyor, and they are moved by the conveyor to pass through the workstations to gradually generate final products. All assembling tasks are manually performed with operation times to be stochastic. An important performance measure of MMALs is overload times that refer to uncompleted operations for operators within their work zones. This paper establishes a method to analyze the expected overload times for MMALs with stochastic operation times. The operation processes of operators form discrete time nonhomogeneous Markov processes with continuous state spaces. For a given daily production schedule, the expected overload times involve in analyzing the Markov processes for finite horizon. Based on some important properties of the performance measure, we propose an efficient approach for calculating the expected overload times. Numerical computations show that the results are very satisfactory. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2007     

Technical note: Worst‐case performance of power‐of‐two policies for serial inventory systems with incremental quantity discounts

This study presents power‐of‐two policies for a serial inventory system with constant demand rate and incremental quantity discounts at the most upstream stage. It is shown that an optimal solution is nested and follows a zero‐inventory ordering policy. To prove the effectiveness of power‐of‐two policies, a lower bound on the optimal cost is obtained. A policy that has a cost within 6% of the lower bound is developed for a fixed base planning period. For a variable base planning period, a 98% effective policy is provided. An extension is included for a system with price dependent holding costs. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2007

周佛海人生三步曲蜕变研究

周佛海曾是出席中国共产党"一大"的十三个代表之一,后来却投靠了国民党右派,再后来卖身给日本侵略者,堕落为臭名昭著的汉奸卖国贼。周佛海人生三步曲的蜕变是由于其个人野心不断恶性膨胀以及对共产主义丧失信念的结果。我们今天从反面总结他一生的教训,对于我们树立正确的人生观很有意义。

《檀香刑》非领格“咱家”的语用分析

“咱家”产生于宋元时代而通用于北方地区,具有方言特色,它用作单数自称时,相当于“我”,在一些地区被用作是带有情感标记的特殊称谓。莫言长篇小说《檀香刑》侧重了这种称谓的特殊性,以它所独有的语气和话语内涵在不同的情景语境中展现说话方自尊自大、傲慢无礼、调侃油滑、玩世不恭等情态,凸现“咱家”男性化的语用特征,从这一角度反映出“咱家”具有的一种倨称语用价值。     

“三个代表”重要思想是新时期治党治国的伟大旗帜——论“三个代表”重要思想的辩证统一性

“三个代表”重要思想开拓了马克思主义在当代中国的新境界,具有解放思想、实事求是、与时俱进的鲜明理论品质及其辩证统一性,是中国共产党历史经验和基本经验的有机统一的反映,是立足现实和展望未来发展要求的有机统一的反映,体现了全面推进党的建设新的伟大工程的辩证统一性。“三个代表”之间具有显著的辩证统一关系。
