推进新农村建设的几个关键问题 总被引:17,自引:0,他引:17
马宝成 《国家行政学院学报》2006,(2):28-31
正确认识当前和今后农村形势是启动新农村建设的前提;由于中国国情和具体政治制度架构等因素,中央政府和各级地方政府在新农村建设中的作用是不同的;新农村建设要注重发挥村庄和农民的主体作用;借鉴国外经验要符合各地具体实际情况,切不可搞“一刀切”,机械照搬。 相似文献

When a governor announces that a tax increase is necessary, how do voters decide whether the governor is representing the situation honestly, or just preparing to line his or her pockets? This paper presents evidence that voters may look at the tax increases in neighboring states to obtain information on whether a tax increase is appropriate and, using this information, decide whether to reelect their governor. The data suggest that comparisons with neighbors influence gubernatorial behavior: Governors are more likely to raise taxes when neighbors are doing the same. TRA86 allows us an extra check on the rnodelpresented: I f the marginal dollar taken in state taxes is more costly to state residents, this may increase the extent to which residents use information provided through neighboring states to sort good governors from bad. 相似文献

Degradation of human DNA extracted from forensic stains is, in most cases, the result of a natural process due to the exposure of the stain samples to the environment. Experiences with degraded DNA from casework samples show that every sample may exhibit different properties in this respect, and that it is difficult to systematically assess the performance of routinely used typing systems for the analysis of degraded DNA samples. Using a batch of artificially degraded DNA with an average fragment size of approx. 200 bp a collaborative exercise was carried out among 38 forensic laboratories from 17 European countries. The results were assessed according to correct allele detection, peak height and balance as well as the occurrence of artefacts. A number of common problems were identified based on these results such as strong peak imbalance in heterozygous genotypes for the larger short tandem repeat (STR) fragments after increased PCR cycle numbers, artefact signals and allelic drop-out. Based on the observations, strategies are discussed to overcome these problems. The strategies include careful balancing of the amount of template DNA and the PCR cycle numbers, the reaction volume and the amount of Taq polymerase. Furthermore, a careful evaluation of the results of the fragment analysis and of automated allele calling is necessary to identify the correct alleles and avoid artefacts. 相似文献
