简析南京国民政府行政督查专员制度存续的原因

南京国民政府初期，采取省县两级管理体制。自1932年开始逐步确立并推及全国的行政督察专员制度(以下用相应的简称)对省县两级制作了实质性的修正。专员制虽然有违国民政府建国大纲，也不被《五五完草》所承认，但仍然得到实施，在于该制弥补了南京国民政府地方行政管理体制的不足，满足了蒋介石扩张势力、掌控地方的政治需要，并且执政根据该制在运行中出现的问题，相应地对有关措施作了调整，使之富有弹性，能更好地发挥政治作用。

数学后进生的非智力因素分析与对策

布卢姆提出的“掌握学习”的理论认为，只要提供合适的环境和足够的学习时间以及适当的帮助，95％的学生能够学好每一门功课。由此看来，学生智力上的差异不是造成后进生的主要原因。

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。
