近年来,多起恶性事件的发生预警了边缘青年受忽视的情绪心理健康问题。作为主要的边缘青年群体,新生代农民工处于青春期这一特定的人生阶段,其心理状态、社会交往及人际交往中的情绪、情感体验都具有一定的特殊性。通过实证研究,本文调查了新生代农民工在当地人际交往中的情绪心理,研究发现,亲密的人际关系对他们的情绪心理健康最具重要性,但实际可依赖的倾诉渠道比较有限。此外,本研究还测量了交往中潜在的情绪心理危机程度,深入挖掘了造成人际交往的内隐性情绪心理问题的主要诱因,建立了有关外部行为的预测指标,探索疏导这一青年群体在人际交往中所存在的情绪问题,以帮助他们提高人际关系的品质,有效预防情绪心理危机。  相似文献

In this study, the Raman spectra of 21 phenethylamines were obtained using far‐red excitation (785 nm). The distinguishing ability of Raman for phenethylamines, especially for phenethylamine regioisomers and structural analogues, was investigated. Here, the evaluation of a cross section of Raman spectra demonstrated that all types of phenethylamines were distinguishable, even for certain structural analogues with high spectrum similarity. Raman exhibited high distinguishing ability for phenethylamine regioisomers that differ in the substitution position of halogen, methoxy, alkyl, or other substituted groups; as well as for structural analogues containing different groups, such as furanyl, 2,3‐dihydrofuranyl, halogen, and alkyl substituted at the same position. The Raman spectra for homologues with differences in only a methyl group were found to be highly similar; however, their spectra demonstrated small but detectable differences. Four analogue mixtures and 59 seized samples were also analyzed to study the practical use of the Raman method in forensic field. 95% of the seized samples were correctly identified, which significantly validated the ability of Raman method in identifying the correct isomers. Accordingly, this study provides a non‐destructive, high‐throughput and minimal sample preparation technique for the discrimination of phenethylamines.  相似文献

针对当代中国城市管理过程中出现的吸纳型监管模式,可以从政治系统论视角进行分析.从输入、输出和反馈的过程来看,吸纳型监管不同于西方自由竞争式的监管内涵,它来源于作为执行输出端的政府职能的折冲,服务于作为支持输入端的政府信任提升,体现出政府存在的需求输入及反馈社会的输出性结果.从监管型国家建设目标来看,以城管执法和官办社团开展的城市吸纳型监管新模式,不等同于社会力量参与治理,难以达到提升监管合法性和有效性的目标.其根源是在城市管理存在政治争议而未经利益博弈的情况下,行政机构的主观性监管很难在管理效率和政治正确之间取得平衡.在此情况下,必须在前端和其他环节嵌入公共参与和公共协商机制,构建协商治理平台,增强政府公共管理活动的政治基础.  相似文献

正From b-boys to Olympic athletesWhen they fell in love with breakdancing,or "breaking," these young boys in beanie hats and baggy clothes never could have imagined this fringe cultural offering would one day become a mainstream Olympic sport.Shang Xiaoyu felt star-crossed when breakdancing foot rocked its way into his life.Considered a "bad student" who frequently skipped class and got into fights with other students in junior middle school,this millennial had no idea how his life could,and would,be changed dramatically by a niche dance genre.Shang was 13.It was a regular day at school when he happened to pass through a classroom where a handful of students were practicing their breaking moves.A mere glance of the scene made him stop in his tracks."This looks super cool,"Shang said."I must learn how to do that."  相似文献

Since the May 4th movement, Chinese New Literature localization and nationalization of the task did not complete, narrative from traditional literature presents the obvious fracture. In the new period historical novels and actively explore the localization of narrative: narrative style from the historical biography and kingdoms; the second is the narrative theme inheriting classical motif; the third is the ancient writings in classical style of narrative language use, inheriting and developing traditional narrative construct with national characteristics of the history novels, and becomes art model of in the context of globalization.  相似文献

随着当今社会风险的不断加剧、不可逆转损害后果的频繁出现,生物多样性保护不应局限于事后的补救性救济,而应当积极拓展其预防功能,将隐患消弭于尚未发生之际是生物多样性预防公益诉讼的应有之义。就现行司法救济体系而言,尚存在法源理论上的不相妥协、立法维度上的事后救济为主、司法实践中的固守谨慎等鲜明特征。因此,应当在风险预防原则与比例原则的引导下,加快推进生物多样性专门立法、明确“重大风险”判断基准、完善生物多样性多元保障体系、打造查、审、执相互贯通的全链条式体系。  相似文献
