将“英特尔~未来教育”理念引入电大课堂

电大远程教育的教育质量是关系到电大系统远程教育成功与失败的大事。保证远程教育的教育质量,课堂是阵地,教学是关键。如何提高课堂教学效果是一个复杂的系统工程,本文提出将“英特尔~未来教育”理念引入电大面授辅导课堂教学之中的设想,以期改善电大面授辅导课的教学效果。他山之石,可以攻玉。笔者希望引入“英特尔~未来教育”理念的电大面授辅导课堂能够充满生机与活力,吸引更多的电大学子回归电大课堂。     

Thermo-mechanical behaviour of floating energy pile groups in sand

This paper presents the experimental results of small-scale model tests of an instrumented floating energy pile group in which the piles were embedded in dry medium-dense sand and subjected to the seasonal temperature pattern of the city of Nanjing in China. The study also included a model test to assess the effect of including nonthermal piles on the thermo-mechanical behaviour of the floating energy pile group. For comparison, a model test of a single floating energy pile embedded in the same soil and subjected to a similar temperature pattern was also conducted. The results show that the thermo-mechanical behaviour of an energy pile group is different from that of a single energy pile in terms of the thermally induced change in axial pile stress and the displacement of the pile top and tip. This difference in behaviour could be explained by the higher lateral confining pressure expected on a single pile than on a pile in a group due to pile interaction effects, which could lead to different end restraint boundary conditions. We conclude that the thermo-mechanical behaviour of an energy pile is controlled mainly by the end restraint boundary conditions.     

我国农产品出口遭遇绿色壁垒制度经济学分析——以安徽省为例

随着关税壁垒作用的弱化，“绿色壁垒”正日益成为国际贸易中非关税壁垒的主要形式。“绿色壁垒”对安徽省乃至全国的农业出口影响重大。农产品出口遇到的“绿色壁垒”，一定程度上反映的是应对“绿色壁垒”的体制缺陷。安徽省应加强制度建设和创新，建立“绿色壁垒”预警机制，明确市场竞争主体，转换政府职能，加大农业基础设施和科技研究投入，提高农业生产的整体水平。     

Bond strength improvement of GFRP rebars with different rib geometries

Based on the Canadian Standards Association (CSA) criteria,105 pullout specimens were tested to investigate the effect of different rib geometries on bond strength of glass fiber reinforced polymer (GFRP) rebars embedded in concrete. Two kinds of conventional reinforcing rebars were also studied for comparison. Each rebar was embedded in a 150 mm concrete cube,with the embedded length being four times the rebar diameter. The experimental parameters were the rebar type,rebar component,rebar diameter,rebar surface texture,rib height,rib spacing and rib width. Theoretical analysis was also carried out to explain the experimental phenomena and results. The experimental and theoretical results indicated that the bond strength of GFRP rebars was about 13%～35% lower than that of steel rebars. The bond strength and bond-slip behavior of the specially machined rebars varied with the rebar type,rebar diameter,rebar surface texture,rib height,rib spacing and rib width. Using the results,design recom-mendations were made concerning optimum rib geometries of GFRP ribbed rebars with superior bond-slip characteristics,which concluded that the optimal rib spacing of ribbed rebars is the same as the rebar diameter,and that the optimal rib height is 6% of the rebar diameter.     

网络民主参与存在的问题及对策

通过对网络民主参与的特点以及网络环境中公民参政议政的现象及在参政议政过程中存在的问题的分析,探讨了政府应对网络民主参与的对策。政府部门一方面要承担起网络基础设施的硬件任务,完善软件系统,为网络民主参与提供平台;另一方面面对网络民主参与出现的种种问题,政府应给予及时的处理与反馈,加强政务的公开和透明,实现政府与公民之间的良性互动,促进和加强公民的网络民主参与。     

微机原理与接口技术实验的教学改革

传统的微机实验教学存在着一定的弊端,根据信息专业的实际情况,按照以学科建设为龙头,突出“一体化”实践教学为内容,加强实践环节,建立完善的微机原理实验教学体系。     

企业文化承担适当责任

上帝创造了世界之后,也创造了动物,于是召开动物大会,来给动物安排寿命。 上帝说:"人的寿命是20年。牛的寿命是50年。鸡的寿命是25年。" 人说:"上帝呀,我非常尊敬您,但是我的寿命也太短了,人生的很多乐趣享受不到了。"上帝还没有说话,牛就说了:"上帝呀,我每天都要干活,您给我30年的寿命,我就要做30年的活儿,太辛苦了,能不能少点。"鸡也说:"我每天报晓也很辛苦,能不能少点寿命。" 上帝说:"好吧,牛和鸡,把你们20年的寿命给人吧。"     

浅析清宣统朝对小国的外交

清朝在宣统朝时,国力更加衰微,无法与列强(英、法、俄、美、日、德)抗争,但已懂得国家利益之所在。在对小国的外交中,清朝按照国际公法和近代外交惯例办理外交,尽力维护国家的权益,这主要表现在更加重视保护华桥,开始重视领海管理权,已注重保护经济等方面的权益     

从来如此,便对么?——试论《阿Q正传·序》的悖反性

鲁迅于《阿Q正传·序》中提出为“不立德、不立功、不立言、无姓、无名、无籍贯”的备受压迫的阿Q作传,以玩笑的口吻打破了封建传统观念中的“不朽说”、“正名论”和“立传通例”,呈现了现实存在对传统观念的重重悖反,也反映了鲁迅对传统观念进行批判的巧妙性和坚定性。     

基于层次分析法的员工绩效诊断

一般员工的工作角色可以描述为五个雏度的工作绩效，在对工作绩效的进一步分析基础上，利用层次分析法可以把定性分析和定量研究结合起来，得出影响工作绩效的各因素所占权重，从而得到工作绩效诊断表。
