高校网络道德教育是一项系统工程,它需要学校、家庭、社会等多方面的共同努力.学校是核心,应承担网络道德教育的主要责任;家庭是补充,应积极配合高校网络道德教育全面开展;社会是保障,应为高校网络道德教育营造良好环境.     

The Viable System Model and Its Application to Complex Organizations

Stafford Beer’s Viable System Model is the best known of the many cybernetic models he constructed over a career spanning more than 50 years. He explored the necessary conditions for viability in any complex system whether an organism, an organization or a country. Although the model was first applied in his work in the steel industry, many further applications were made during his later work as a consultant. The best known of these was when he was invited by President Salvadore Allende of Chile in 1970 to model the social economy of that country. That experiment was brutally cut short in 1973 by the CIA assisted coup during which Allende was killed and Pinochet’s dictatorship installed. The model itself draws on mathematics, psychology, biology, neurophysiology, communication theory, anthropology and philosophy. It was first expressed in mathematical terms in ‘The Cybernetic Factory’; next it was described in neurophysiological terms in Brain of the firm; and finally according to logic and graphic presentation in Heart of Enterprise and Diagnosing the System for Organizations. This last version is the one that is most accessible. It enables people to address organizational issues in a way that skirts the usual categories and organization charts and gets down to the actual necessary functions, no matter who is performing them. With this model people can get a boost as they diagnose or design an organizations. One aspect is to discover what the organization’s critical variables are and to find or install the homeostats that will show that they are maintaining equilibrium. Within that context, the model will help you ascertain that the principle functions and communications channels are in place and can function effectively. A crucial aspect of the VSM is that it is recursive; that is that the same relationships can be traced from the shop floor to the corporation or from the village to the country. Two examples will be discussed: a small business and the Chilean work from the 1970s. It is hoped that this will encourage people to imagine a world that works much better than it does now and where management is not defeated by complexity. A version of this paper was delivered as the first Stafford Beer Memorial Lecture on July 8, 2007 at the World Multiconference on Systems, Cybernetics and Informatics in Orlando Florida.

《PLC编程及应用》课程教学改革与实践

针对“PLC编程及应用”课程的教学现状与存在的问题,结合课程、教材及学生的特点,提出要多种教学法并用,重点实施项目教学法,突出工程意识,注重PLC控制系统的整体设计。并从现存问题、教学手段、实验体系等方面进行探讨和实践。在课程的教学中引入项目教学法,帮助学生提高动手能力,把握从PLC程序设计到组建PLC工作系统的全过程,培养学生主动获取知识和独立解决问题的能力,构建开放性教学体系。     

新一轮西部大开发背景下西部新建本科院校发展研究

西部新建本科院校的发展与国家实施西部大开发和高校扩招战略相伴相随。西部新建本科院校在为地方经济社会发展提供人才和智力支持、切实为推进西部大开发服务的同时,自身也得到了发展壮大,一部分学校并由此逐渐培育起办学特色和优势,走上了科学、协调、可持续的发展道路。在新一轮西部大开发的背景下,西部新建本科院校应继续深化改革开放,加快转变发展方式,紧贴地方产业特色和优势,突出地方性和应用型,进一步巩固和增强办学特色,实现学校又好又快科学发展。     

三峡工程对长江口南汇边滩近期演变影响初步预测

利用DELFT3D模型建立了长江口二维泥沙数学模型,通过实测水文泥沙资料对模型进行了验证.在此基础上,分别将上游洪、枯季流量概化和外海典型潮波组合,建立了长期冲淤模型.通过10年实测地形资料对模型进行的验证,显示该模型较好地模拟了长江口水沙运动以及长期冲淤演变过程.考虑三峡工程蓄水后上游来水来沙的变化,对近期南汇边滩的演变趋势给出预测,结果显示:三峡工程实施之后的5～20年,南汇边滩发育基本稳定,上游来沙量的减少不会造成大幅度冲刷,边滩整体继续向东南方向演变.     

Zircon (U-Th)/He thermochronological constraints on Cretaceous thermal extension of Dabieshan orogen

：(U-Th)/He ages of 13 samples from Yuexi-Luotian core and its flanks in Dabieshan orogen fall in the range of 155～85 Ma. He ages for samples from the core range between 85～107 Ma, while those from the flanks range between 114～155 Ma. The result shows that the Yuexi-Luotian core was a thermal dome in Cretaceous with core temperature being much higher than those of the flanks. The thermal extension which resulted in the formation of Dabie core complex lasted until ca. 85 Ma. The magnitude of exhumation in the core is approximately 1528.8 m more than that in the flanks.

葛洲坝水利枢纽工程对宜昌河段水文水力特性的影响

根据葛洲坝水库蓄水前后宜昌水文站水文实测资料,分析了葛洲坝水利枢纽工程对宜昌河段水位-流量关系、断面形状和水位变化规律的影响.结果表明,葛洲坝水库蓄水后,宜昌河段水文水力特征变化符合惯性区理论,洪水波运动形式发生变化,坝前水流流速降低,水流挟沙能力和推移力下降,水库淤积现象加重,下泄水流中的含沙量下降,宜昌河段推移质输入减少,下泄水流对河道的冲刷能力增强,原有的冲淤平衡被打破,河床质变粗,断面形状不断变化,宜昌河段河床下切、水流能量增大、流速增大,同流量情况下的水位较天然河道有所下降.
