摘要：当前,我国社会老龄化形势对社会化养老服务以及住区涉老服务设施提出了新的需求。论文在分析现有涉老设施规划建设的相关规范标准和总结城市涉老设施规划建设中存在的问题的基础上,以完善我国城市住区养老设施规划建设标准体系为目标,对城市住区涉老服务设施的分类、分级及配建布局等具体指标展开研究,提出了适合我国深度老龄化阶段的养老发展需求的城市住区涉老设施规划建设标准的新指标。

摘要：在乡村振兴战略背景下,农村劳动力就业问题显得尤为突出。职业培训作为一种促进农民就业的方式,近年来愈发受到关注。然而,通过家政职业培训促进农村劳动力就业也面临着职业培训机制不完善、培训针对性不强、参与对象认可度低和农民家政职业素质基础低的问题。清远“南粤家政”公益训练营的实践表明,构建完整的就业帮扶链条和工作机制,在职业培训中突出课程内容的针对性和职业性,以及扶持地区性家政服务品牌和人才队伍,有助于促进农村劳动力就业问题的解决。同时,通过优化政府的角色和定位、提升职业院校的社会服务能力、构建家政兴农的良好社会环境和社会氛围等路径,可以推进家政职业培训助力农村劳动力就业和乡村产业振兴、人才振兴走向深化。

摘要：本文基于景观生态学和生态控制的原理,提出以景观格局、景观生态过程以及人类活动与景观的相互作用为核 心的“景观生态调控”的概念。景观生态调控的基本原理可归纳为:竞争和共生、正负反馈、增殖和自我补偿、废物循环利 用、最小风险、生态适应性、景观结构和功能、景观多样性和稳定性、生态整体性与空间异质性等。景观生态调控的方法框 架包括:景观生态规划(整体共生方法)、景观生态工程设计与建设(循环再生方法)、景观生态管理(竞争自生方法)。

摘要：The typical Haber technical process for industrial NH_(3)production involves plenty of energy-consumption and large quantities of greenhouse gas *** contrast,electrochemical N_(2)reduction proffers environment-friendly and energy-efficient avenues to synthesize NH_(3)at mild conditions but demands efficient electrocatalysts for the N_(2)reduction reaction(NRR).Herein we report for the first time that commercial indium-tin oxide glass(ITO/G)can be used as a catalyst electrode toward artificial N_(2)fixation,as it demonstrates excellent selectivity at mild *** ITO/G delivers excellent NRR performance with a NH_(3)yield of 1.06×10^(-10) mol s^(-1) cm^(-2) and a faradaic efficiency of 6.17%at-0.40 V versus the reversible hydrogen electrode(RHE)in 0.5 M ***,the ITO/G also possesses good electrochemical stability and ***,the possible reaction mechanism for the NRR on the ITO catalysts was explored using first-principles calculations.

摘要：外国诗歌鉴赏导航[外国诗歌鉴赏的意义]诗歌是最古老的文学艺术,是各民族文化的精华,是世界文学作品中的奇葩.每个国家的诗都根植于民族的土壤之中,每个国家都蕴藏着丰富的创作源泉:有独具个性的山川河流,有独特的文化生活,有各自的信仰情趣,有民族的风俗习惯,这些多彩的自然和社会资源,是各国诗人创作的丰厚营养.外国诗歌反映不同的生活习俗、文化底蕴和民族特性,同样能滋润不同国度人们的心灵,陶冶人们的性情,丰富人们的精神文化生活.

摘要：The optoelectronic properties of atomically thin transition metal dichalcogenides(TMDs)are largely influenced by defect populations(DPs).In this work,we fabricate WSmonolayers with different DPs by varying the fabrication methods and further reveal their distinct exciton-exciton ***-state photoluminescence(PL)experiments show that the monolayer with the lowest DP shows optimal PL intensity at low excitation power;however,it is overtaken and significantly surpassed by monolayers with higher DPs at high excitation ***-power-dependent experiments demonstrate that these monolayers exhibit distinct PL saturation behaviors with the threshold power differing by four orders of *** with in situ PL imaging and time-resolved PL experiments,we attribute such PL evolution discrepancies to the different DPs within these monolayers,which largely influence the exciton diffusion behavior and subsequently bring about distinct nonradiative exciton-exciton annihilations(EEAs).Valley polarization experiments are further employed to re-examine the DPs of these *** work reveals the distinct PL behaviors and underlying exciton dynamics in TMD monolayers with different DPs,which can largely facilitate the engineering of relevant high-performance devices for practical applications.

摘要：目的探讨规范化培训对提高低年资护士核心能力的效果,为完善规范化培训方案提供依据。方法选取2011年至2012年168名新入职护士为对照组,采用传统低年资护士培训方案;选取2013年至2014年185名新入职护士为观察组,采用规范化培训方案,包括组建专项培训队伍,制订新护士分层培训计划及考核要求,实施岗前培训和临床轮转培训模式,应用现场培训与在线学习相结合的培训方法。培训结束后,比较两组新入职护士核心能力得分情况及满意度。结果观察组新入职护士在临床核心能力得分及对培训内容、定科方案、培训形式、考核方案的满意度均高于对照组,两组比较差异有统计学意义(P<0.05)。结论规范化培训对提升护士核心能力具有显著作用,护理人员对规范化培训的满意度较高。护理管理者需要进一步科学设计培训内容和方案,重视低年资护士培训需求,保障规范化培训效果。
