反腐倡廉是当前必须抓好的重大政治任务,也是不断增强人民群众幸福感的重要保障。然而,当前研究多从反腐败斗争和廉政建设两条路径来解释反腐倡廉对幸福感的影响,忽略了其一体两面的政策特征。实证研究结果发现,反腐倡廉政策框架有助于提高居民幸福感,相较于反腐框架,倡廉框架的影响更为显著。象征性代表和权力距离取向是反腐倡廉政策框架增进幸福感的内在影响因素。象征性代表在反腐倡廉政策框架增进幸福感的过程中发挥中介作用,权力距离取向能有效调节象征性代表对幸福感的影响,同时权力距离取向可以调节反腐倡廉通过象征性代表对幸福感的间接效应。

Lagoons.are ecos.s.ems.for biodivers.ty and the livelihoods.of coas.al communities. The main objective of the s.udy was.to analyze the variability of ars.nic concentrations.in gas.ropods.and bivalves.in the Aby and Tendo lagoons. taking into account s.atial, s.as.nal and hydrological variations. The s.udy was.carried out in four s.ages.s.read over two s.cces.ive hydroclimatic cycles. including two s.as.ns.during the rainy s.as.n and two more during the dry s.as.n. The s.mples.were taken in two areas.of the Aby and Tendo lagoons. Ars.nic levels.were meas.red by ICP-Ms. The res.lts.s.owed that mean ars.nic concentrations.in the mus.les.of organis.s.in Aby Lagoon ranged from 0.01 to 1.26 μg As.g, with a mean and median of 0.17 and 0.06 μg As.g, res.ectively.

Ars.nic concentrations.in tilapia and jawbones.varied s.gnificantly between s.tes.and s.as.ns. with higher concentrations.at Tendo and during the rainy s.as.n.

In the purpos. to des.gn novel antituberculos.s.(anti-TB) drugs.agents.agains. Mycobacterium tuberculos.s.(Mtb), we have built a molecular library around 42 Halimane Diterpenoids.is.lated from natural s.urces. Two Mtb enzymes.drug targets.(Mtb Mycothiol s.trans.eras. and Mtb Homos.rine trans.cetylas.) have been adopted. The pharmacological potential was.inves.igated through molecular docking, molecular dynamics.s.mulation, dens.ty functional theory (gas.phas. and water) and ADMET analys.s. Our res.lts.indicate that (2R,5R,6s.-1,2,3,4,5,6,7,8-octahydro-5-((E)-5-hydroxy-3-methylpent-3-enyl)-1,1,5,6-tetramethylnaphtha-lene-2-ol (compound 20) has.dis.lays.higher docking s.ore with each of the s.lected drug targets. In addition, this.molecule exhibits.a s.tis.actory drug potential activity and a good chemical reactivity. Its.improved kinetic s.ability in the Mtb Mycothiol s.trans.eras. enzyme reflects.its.s.itability as.a novel inhibitor of Mtb growth. This.molecule has.dis.layed a good abs.rption potential. Our res.lts.als. s.ow that its.pas.ive pas.age of the intes.inal permeability barrier is.more effective than that of firs.-line treatments.(ethambutol, is.niazid).

文章基于2011—2020年中国省域面板数据,通过熵权-修正耦合模型度量了中国省域数字经济与实体经济深度融合水平,刻画了数实融合的动态演进趋势,利用修正障碍因子模型识别了中国省域数实融合的障碍因子。研究结果表明:1)经过10年的发展,中国各省份数字经济、实体经济及其深度融合水平都取得了长足的进步,2020年中国数实融合平均水平达到了0.3218,总体上处于中度融合水平。2)“十二五”时期数实融合水平处于平稳发展状态,“十三五”时期的后两年提升幅度较大,且省际数实融合水平存在极化趋势。3)中国数实融合的主要障碍来源于数字经济子系统,最大的障碍因子为数字技术环境,该障碍主要源于技术研发环境。4)数字技术环境的缺位和数字技术人才的缺失是各个地区数实融合的主要障碍,东北地区比较特殊,其工业方面的障碍大于数字基础设施的障碍。5)数字技术环境、数字技术人才和数字产业化三个障碍因子并未随两个五年规划的更迭而变化,表明三者是中国目前及将来很长一段时间内数实融合的主要障碍。
