央企集团总部改革的收与放

总部改革的关键是处理好总部权力＂收＂与＂放＂的关系,实现＂管好＂与＂放活＂。我国相当一部分大型国有企业集团的母公司,是从行业管理部门演变而来的。从长期改革实践来看,集团总部的机构改革是＂龙头环节＂,也是改革的敏感点和难点。完成好企业集团总部改革,即在科学定位总部功能的基础上,朝着强化宏观管理、下放微观权力、

Isolation and Characterization of a Bensulfuron-Methyl-Degrading Strain L1 of Bacillus

The objectives of this study were to isolate a bensulfuron-methyl （BSM）-degrading strain of Bacillus spp. and to evaluate its effectiveness in remediation of a BSM-contaminated soil. A BSM-degrading bacterium, strain L1, was successfully isolated in this study. Strain L1 was identified as Bacillus megaterium based on its morphological, physiological, and biochemical properties, G＋C content, phylogenetie similarity of 16S rDNA, and fatty acid composition. Two experiments were used to examine BSM degradation by strain L1. When BSM was used as a sole carbon source in a mineral salt medium, the average degradation rate of BSM by strain L1 was 12.8%, which suggested that the strain was able to utilize BSM as a sole carbon and energy source. Supplement of yeast extract （200 mg L^-1） significantly （P ≤ 0.01） accelerated the degradation of BSM by strain L1. Ahnost complete degradation （97.7%） of BSM could be achieved in 84 h with addition of yeast extract. In addition, in a sterile soil with 50 mg L^-1 BSM, BSM degradation rate by strain L1 was 94.3% in 42 d, indicating the potential of using microbes for the remediation of BSM-contaminated soils in fields.

财务视角下的高校科研项目管理评析

自中央"放管服"精神在科技领域不断落实以来,高校财务部门日益加强管理、提升服务,但由于财务部门管理和服务职能界限模糊,科研项目管理流程繁琐复杂,科研人员应对科研经费管理的压力仍然巨大。从财务管理视角出发,从科研项目预算方式调整、科研经费的管理与服务功能分离、科研经费差别化管理、科研项目验收回归成果本质四个方面提出解决当前科研管理问题的合理思路。
