必须大力实施好再就业工程

本文在分析我国目前就业所面临的主要问题和从理论上论证失业是市场经济条件下的正常现象的基础上，说明政府必须在当前再就业工程中发挥主导作用，并具体提出六项政策建议。     

突发模式下PSK信号的载波估计和位同步技术

介绍了一种适合于突发模式下PSK信号的快速载波估计和位时钟恢复的算法,该算法基于特定图案的前导字,在前导字阶段采用匹配滤波相关的前向技术直接获取载波频差估计值和位同步时钟的相位信息,利用数字相关得到载波初相的估计值.此算法结构简单,可估计的载波频差范围约为符号率的±10%,且计算量不大,适合数字硬件实现.实测结果验证了该方法的可行性和有效性.     

不完美碰撞检测的CSMA/CA协议性能分析

传统中低轨小卫星群的移动自组织网络中，卫星采用半双工载波侦听/碰撞规避协议（Carrier Sensing Multi-access/Collision Avoidance,CSMA/CA）接入控制信道。为避免半双工模式“盲听”对碰撞感知存在的延时，提升接入效率，卫星需要工作在碰撞检测和数据接收同步进行的全双工模式；同时由于卫星通信特点，残余自干扰带来的不完美碰撞检测不可忽略。针对以上需求，设计了一种全双工CSMA/CA协议，对接入流程和参数进行了详细描述；研究了自干扰抑制度和检测门限等与虚警率、漏检率的数学关系；推导了系统吞吐量的解析表达式，并仿真探究了初始竞争窗口长度等参数的优化设计准则。仿真结果表明，通过合理选取参数，该协议能在存有不完美碰撞检测的情况下，实现吞吐量的提升。     

完善廉政文化社会化的传递机制研究

廉政文化社会化是廉政文化建设的主体有意识地向该文化的承载者实施主动教育和灌输的过程。目前廉政文化社会化表现为载体不丰富、媒介影响有限、传递机制不顺畅,究其原因,是由于研究的滞后性思想上的误区、制度缺陷、公众参与冷淡,从完善载体、媒介与疏通传递机制提出相应的政策建议。     

In-flight physical surroundings: quality,satisfaction, and traveller loyalty in the emerging low-cost flight market

The purpose of our research was to investigate the relationships among overall service quality, customer satisfaction, and behavioural intentions by considering the moderating impact of in-flight ambient conditions (air quality, temperature, odour, and noise) in the low-cost airline industry. A survey was conducted on international flights. Results of the structural equation modelling from a sample of 402 passengers indicated that quality and satisfaction are significant drivers of intentions; and satisfaction acted as a significant mediators. Additionally, supporting the moderating impact of ambience, findings from the tests for metric invariance revealed that the effect of satisfaction on intentions was stronger for the high air quality, temperature, odour, and noise groups than for the low groups; and the strength of the relationship between quality and intentions was greater in the high noise group than in the low noise group. Our results will help practitioners/researchers develop effective strategies/theories for passenger satisfaction and retention.     

论大学生艺术团在思想政治教育中的作用

新形势下的高校思想政治教育方式在向主体间性范式调整和改变,通过主导和引导大学生艺术团的活动内容和形式,可以强化受教育者的主体性,发挥其思想政治教育方面的独特作用。大学生艺术活动融入了思想政治教育主旨和主题,可以与高校思想政治课堂教育方式相辅相成,以其感兴和感化的教育方式,达到"润物细无声"的效果。     

以数学建模竞赛为载体培养应用型人才实践创新能力

以数学建模竞赛活动为有效载体,通过优化人才培养方案、健全学科竞赛运行机制、加强创新教育基地建设等有效手段,培养学生的实践创新能力,全面提高学生的创造力和综合素质。     

电子版公布策略的经济学分析

有一类产品,既有实物载体,也可以有电子载体,且不同形式的载体给消费者带来的效用有所不同。对于这类产品,其电子版在网络上的传播往往被视为盗版;但也有相反的情况:厂商主动将免费的电子版公布到网上,可是实物产品的销售不但没有减少,反而增加。文章研究发现,当高端客户比例和产品符合其需求的顾客比例较高时,免费的电子版不但不应该视为盗版,而且还可以作为一种营销工具,利用口碑传播来扩大潜在的顾客群,从而促进实物产品的销售,最大化企业利润。文章对这一问题建立了规范模型,讨论在各种不同情况下厂商的电子版公布策略与相应的价格策略。     

高校计算机机房管理的探讨

随着信息技术的广泛应用，高校计算机房利用率越来越高。网络技术的发展赋予机房管理工作新的内涵，机房的管理是公认的难事。唯有采取有效的措施，才能确保机器、系统安然无恙。教学机房现代化管理不仅需要实现事务性管理的计算机化，还需要适应网络环境实现管理网络化。     

Airport competition - Regional airports losing ground to main airports

Regional airports in Norway are losing market shares to nearby main airports on flights to the national capital, Oslo, and on international travel via Oslo. Travellers are willing to spend several hours extra driving to a larger airport in order to take advantage of lower fares and more convenient airline services. Traffic leakage from regional airports is high when the service from the regional airport is indirect and fare differences are large. Public service obligation tenders (PSO) set maximum fares on the regional legs, but do not cover through travel from regional airports which involve commercial legs. Traffic leakage is particularly evident in the leisure segment. Leakage levels tend to increase as competition is intensified at main airports, but the evidence is rather mixed. Logistic curves of airport market shares have proven to be useful when comparing spatial variations in leakage levels.
