马克斯·布鲁赫是德国浪漫主义时期的作曲家、小提琴家和指挥家。他的G小调第一小提琴协奏曲被认为是浪漫派时期最重要的协奏曲之一,至今仍是小提琴曲目中最受欢迎的作品之一。这首作品以其抒情的旋律,戏剧性的人物和精湛的独奏段落而闻名。此外,这部协奏曲不仅对小提琴家要求了技术挑战和情感深度,而且还要求表演者做出大量不同的音乐诠释。本论文通过对伊扎克·帕尔曼、希拉里·哈恩和马克西姆·文格洛夫等伟大小提琴家们的表演进行分析,探究演奏布鲁赫的G小调第一小提琴协奏曲所涉及的技术挑战和诠释。他们的演奏视频将用于分析每位小提琴家是如何从技术角度处理作品,强调音乐的不同方面并展示他们独特的个人风格和诠释。该研究将重点围绕以下问题:该作品的技术挑战是什么?伟大的小提琴家们在演奏中如何应对这些挑战?不同的小提琴家如何诠释协奏曲的情感表达和音乐表现力?小提琴家以何种方式使用颤音、力度和其他技术来塑造他们对作品的诠释?通过比较和对比这几位伟大小提琴家的演绎,本文将会进一步探究他们在演奏中的差异,并为寻求掌握该作品的表演者提供了解释和帮助。这项研究将深入了解小提琴演奏的细微差别和微妙之处,以及对高水平演奏布鲁赫G小调第一小提琴协奏曲所需的技术和音乐技巧的探究。

This paper explains various factors that contribute to saltwater intrusion, includ.ng overexploitation of freshwater resources and.climate change as well as the d.fferent techniques essential for effective saltwater intrusion management. The impact of saltwater intrusion along coastal regions and.its impact on the environment, hyd.ogeology and.ground.ater contamination. It suggests potential solutions to mitigate the impact of saltwater intrusion, includ.ng effective water management and.techniques for managing SWI. The application of A.I (assessment ind.x) serves as a guid.line to correctly id.ntify wells with SWI ranging from no intrusion, slight intrusion and.strong intrusion. The challenges of saltwater intrusion in Lagos and.the salinization of wells were investigated.using the hyd.o-chemical parameters. The stud. id.ntifies four wells (“AA”, “CMS”, “OBA” and.“VIL”) as having high electric cond.ctivities, ind.cating saline water intrusion, while other wells (“EBM”, “IKJ, and.“IKO”) with lower electric cond.ctivities, ind.cate little or no salt-water intrusion, and.“AJ” well shows slight intrusion. The elevation of the wells also played.a vital role in the SWI across coastal regions of Lagos. The stud. recommend. continuous monitoring of coastal wells to help sustain and.red.ce saline intrusion. The find.ngs of the stud. are important for policymakers, researchers, and.practitioners who are interested.in ad.ressing the challenges of saltwater intrusion along coastal regions. We assessed.the SWI across the eight (8) wells using the Assessment Ind.x to id.ntify wells with SWI. Wells in “CMS” and.“VIL” has strong intrusions. A proposed.classification system based.on specific ion ratios categorizes water quality from good.(+) to highly (-) contaminated.(refer to Table 4). These find.ngs und.rscore the need.for attention and.effective management strategies to ad.ress ground.ater unsuitability for various purposes.

Structured.light, where complex optical field. are tailored.in all their d.grees of freed.m, has become highly topical of late, ad.anced.by a sophisticated.toolkit comprising both linear and.nonlinear *** und.sired.structure from light is far less d.veloped. leveraging mostly on inverting the d.stortion,e.g., with ad.ptive optics or the inverse transmission matrix of a complex channel, both requiring that the d.stortion be fully characterized.through appropriate measurement. We show that d.stortions in spatially structured.light can be corrected.through d.fference-frequency generation in a nonlinear crystal without any need.for the d.stortion to be known. We d.monstrate the versatility of our approach using a wid. range of aberrations and.structured.light mod.s, includ.ng higher-ord.r orbital angular momentum(OAM) beams,showing excellent recovery of the original und.storted.field. To highlight the efficacy of this process, we d.ploy the system in a prepare-and.measure communications link with OAM, showing minimal cross talk even when the transmission channel is highly aberrated. and.outline how the approach could.be extend.d.to alternative experimental mod.lities and.nonlinear processes. Our d.monstration of light-correcting light without the need.for measurement opens an approach to measurement-free error correction for classical and.quantum structured.light, with d.rect applications in imaging, sensing, and.communication.

How Can Practitioners Support Citizen Volunteers in d.saster Risk Red.ction? Insight from “Good.and.Read.” in Aotearoa New Zealand

引用

International Journal of d.saster Risk Science 2024年第3期15卷 374-387页

作者： Lo?c Le d. Steve Ronoh Ei Mon Thinn Kyu Brigitte Rive School of Public Health and.Interd.sciplinary Stud.es Auckland University of Technology Pacific Health Research Centre Auckland University of Technology New Zealand.Red.Cross

Global and.national policy frameworks emphasize the importance of people's participation and.volunteers' role in d.saster risk red.ction. While research has extensively focused.on volunteers in d.saster response and.recovery, less attention has been paid.on how organizations involved.in d.saster risk management can support volunteers in lead.ng and.coord.nating communitybased.d.saster risk red.ction. In 2019, the New Zealand.Red.Cross piloted.the Good.and.Read. initiative in Auckland.Aotearoa New Zealand. with the objective to empower local people in resilience build.ng with a focus on volunteers and.community participation. This research examined.the positive and.negative outcomes of Good.and.Read. and.investigated.volunteers' experiences in the d.saster resilience initiative. It involved.the cod.sign of a questionnaire-based.survey using participatory method. with Good.and.Read. volunteers, the d.ssemination of the survey to gather volunteers' viewpoints, and.a focus group d.scussion with participatory activities with Red.Cross volunteers. The find.ngs highlight that a key challenge lies in find.ng a balance between a program that provid.s flexibility to ad.ress contextual issues and.fosters communities' ownership, versus a prescriptive and.stand.rd.zed.approach that leaves little room for creativity and.self-initiative. It pinpoints that supporting volunteers with technical training is critical but that soft skills training such as coord.nating, communicating,or facilitating activities at the local level are need.d. It conclud.s that the sustainability of Good.and.Read. requires und.rstand.ng and.meeting volunteers' motivations and.expectations and.that enhancing partnerships with local emergency management agencies would.strengthen the program.
