Design of a Socially Inclusive Climate Risk Transfer Mechanism: A Case Study in La guajira, Colombia

INTERNATIONAL JOURNAL OF DISASTER RISK SCIENCE 2024年第4期15卷 565-578页

作者： Lopera, Cristian camilo Fernandez Mendes, Jose Manuel Barata, Eduardo Jorge Univ Coimbra Inst Interdisciplinary Res Ctr Social Studies P-3000995 Coimbra Portugal Univ Coimbra Fac Econ Ctr Social Studies P-3000995 Coimbra Portugal Univ Coimbra Fac Econ CeBER P-3004512 Coimbra Portugal

The primary aim of this study was to develop a model of a socially inclusive climate risk insurance (CRI) mechanism based on the differential risk transfer approach. This study focused on the department of La guajira, Colombia, as a case study. La guajira is the department in Colombia that, due to its critical disaster risk conditions, presents the adequate configuration for implementing a climate risk transfer mechanism. The article starts by analyzing risk conditions by using secondary data. Based on fieldwork, this research explored the perspectives of the most vulnerable sectors in La guajira Department on the socioeconomic impacts and needs they experience regarding climate-related hazards, their adaptive measures for risk reduction, and their willingness to adopt CRI. This represents the fundamental input for the formulation of the CRI model. Consequently, this research proposed an operational structure as input for future implementations of the model. The results indicate that national and local disaster risk management public policies align with the sectors' needs and priorities. Strengthening sectoral associations can enhance representation in CRI projects. In-kind indemnization is preferred for women entrepreneurs and the indigenous community. The CRI model includes a risk pool through the family compensation fund of La guajira as a sectoral agglomerator, with contingent credit and traditional/parametric insurance. The methodology developed in this study can be applied in different contexts worldwide as a guidance for informing national and international climate risk finance initiatives.

对演奏者来说,对于作品的演奏诠释是一种挑战。要想使作品被清晰地理解,就必须努力实现作品中音乐语言的正确传递。为正确的诠释和演奏作品,就需要了解其和声结构、弓法和演奏(运弓)技巧。因此,对不同手稿和版本的搜寻,和对作品中每部分对于乐句中弓法的运用的分析,就变得重要。不同手稿对于鞠躬和发音的不同标示,使不同版本之间会产生相反表达。在贝蒂娜·施韦默和道格拉斯·伍德富尔·哈里斯编写的《约翰·塞巴斯蒂安·巴赫六首大提琴组曲BWV 1007-1012》中可以窥知著名大提琴家们对于不同版本弓法的选择,演奏技法的运用,以及他们对于不同版本的看法。根据对不同手稿中不同的演奏意图和要求达成了共识,和谱面上弓法的标示,使得这一版本成为了巴赫第五组曲中前奏曲弓法与演奏技法的权威版本。基于对作品的分析,本文的目的在于,在一系列动机中找到一致性,以建立最合适的演奏技法。虽然这些手稿大都提供的都是巴洛克风格的演奏建议;但同时也考虑到了当代表演者,并根据现代大提琴及其风格提出了建设性的意见。同时,结合对音乐风格的考量,在掌握了演奏技巧后,演奏者会对作品有更深刻的理解。这些理解会引导演奏者以更诗意和深刻的方式,更好的演绎巴赫的作品。

The pyramid wavefront sensor(PWFS)can provide the sensitivity needed for demanding adaptive optics applications,such as imaging exoplanets using the future extremely large telescopes of over 30 m of diameter(D).However,its exquisite sensitivity has a limited linear range of operation,or dynamic range,although it can be extended through the use of beam modulation—despite sacrificing sensitivity and requiring additional optical *** by artificial intelligence techniques,this work proposes to train an optical layer—comprising a passive diffractive element placed at a conjugated Fourier plane of the pyramid prism—to boost the linear response of the pyramid sensor without the need for cumbersome *** develop an end-2-end simulation to train the diffractive element,which acts as an optical preconditioner to the traditional least-square modal phase estimation *** results with a large range of turbulence conditions show a noticeable improvement in the aberration estimation performance equivalent to over 3λ∕D of modulation when using the optically preconditioned deep PWFS(DPWFS).Experimental results validate the advantages of using the designed optical layer,where the DPWFS can pair the performance of a traditional PWFS with 2λ∕D of *** and adding an optical preconditioner to the PWFS is just the tip of the iceberg,since the proposed deep optics methodology can be used for the design of a completely new generation of wavefront sensors that can better fit the demands of sophisticated adaptive optics applications such as ground-to-space and underwater optical communications and imaging through scattering media.

Optimal Coordinated Operation of Distributed Static Series Compensators for Wide-area Network Congestion Relief

引用

Journal of Modern Power Systems and Clean Energy 2022年第5期10卷 1374-1384页

作者： camilo Andres Ordonez M Antonio gomez-Exposito guillermo EVinasco M Jose Maria Maza-Ortega IEEE Smart Wires Union CityUSA Department of Electrical Engineering University of SevilleSevillaSpain Interconexion Electrica SA Intercolombia Sevilla Spain

Relieving network congestions is a critical goal for the safe and flexible operation of modern power systems, especially in the presence of intermittent renewables or distributed generation. This paper deals with the real-time coordinated operation of distributed static series compensators(DSSCs) to remove network congestions by suitable modifications of the branch reactance. Several objective functions are considered and discussed to minimize the number of the devices involved in the control actions, the total losses or the total reactive power exchanged, leading to a non-convex mixed-integer non-linear programming problem. Then, a heuristic methodology combining the solution of a regular NLP with k-means clustering algorithm is proposed to get rid of the binary variables, in an attempt to reduce the computational cost. The proposed coordinated operation strategy of the DSSCs is tested on several benchmark systems, providing feasible and sufficiently optimal solutions in a reasonable time frame for practical systems.

A sedentary lifestyle and obesity are important risk factors for severe COVID-19 complications and death[1,2].Excessive adipose tissue(AT)might contribute to more extensive viral spread with increased shedding,immune activation,and cytokine amplification[3].Several factors secreted by contracting muscle,termed myokines,mediate the beneficial effects of exercise in a wide range of diseases,including obesity[4].Thus,we conducted a study to explore the potential role of myokines of the fibronectin type III domain-containing family,FNDC4 and FNDC5,in mechanisms underlying the increased susceptibility to COVID-19 complications in obesity.
