Information Management in Disaster and Humanitarian Response: A Case in United Nations Office for the Coordination of Humanitarian Affairs

To guarantee a unified response to disasters, humanitarian organizations work together via the United Nations Office for the Coordination of Humanitarian Affairs (OCHA). Although the OCHA has made great strides to improve its information management and increase the availability of accurate, real-time data for disaster and humanitarian response teams, significant gaps persist. There are inefficiencies in the emergency management of data at every stage of its lifecycle: collection, processing, analysis, distribution, storage, and retrieval. Disaster risk reduction and disaster risk management are the two main tenets of the United Nations’ worldwide plan for disaster management. Information systems are crucial because of the crucial roles they play in capturing, processing, and transmitting data. The management of information is seldom discussed in published works. The goal of this study is to employ qualitative research methods to provide insight by facilitating an expanded comprehension of relevant contexts, phenomena, and individual experiences. Humanitarian workers and OCHA staffers will take part in the research. The study subjects will be chosen using a random selection procedure. Online surveys with both closed- and open-ended questions will be used to compile the data. UN OCHA offers a structure for the handling of information via which all humanitarian actors may contribute to the overall response. This research will enable the UN Office for OCHA better gather, process, analyze, disseminate, store, and retrieve data in the event of a catastrophe or humanitarian crisis.

DISRUPTION MANAGEMENT FOR SUPPLY CHAIN COORDINATION WITH EXPONENTIAL DEMAND FUNCTION

The coordination problem of a supply chain comprising one supplier and one retailer under market demand disruption is studied in this article. A novel exponential demand function is adopted, and the penalty cost is introduced explicitly to capture the deviation production cost caused by the market demand disruption. The optimal strategies are obtained for different disruption scale under the centralized mode. For the decentralized mode, it is proved that the supply chain can be fully coordinated by adjusting the price discount policy appropriately when disruption occurs. Furthermore, the authors point out that similar results can be established for more general demand functions that represent different market circumstances if certain assumptions are satisfied.

Energy Management of Networked Smart Railway Stations Considering Regenerative Braking, Energy Storage System, and Photovoltaic Units

The networking of microgrids has received significant attention in the form of a smart grid.In this paper,a set of smart railway stations,which is assumed as microgrids,is connected together.It has been tried to manage the energy exchanged between the networked microgrids to reduce received energy from the utility grid.Also,the operational costs of stations under various conditions decrease by applying the proposed method.The smart railway stations are studied in the presence of photovoltaic(PV)units,energy storage systems(ESSs),and regenerative braking strategies.Studying regenerative braking is one of the essential contributions.Moreover,the stochastic behaviors of the ESS’s initial state of energy and the uncertainty of PV power generation are taken into account through a scenario-based method.The networked microgrid scheme of railway stations(based on coordinated operation and scheduling)and independent operation of railway stations are studied.The proposed method is applied to realistic case studies,including three stations of Line 3 of Tehran Urban and Suburban Railway Operation Company(TUSROC).The rolling stock is simulated in the MATLAB environment.Thus,the coordinated operation of networked microgrids and independent operation of railway stations are optimized in the GAMS environment utilizing mixed-integer linear programming(MILP).

Evaluating the Relationship between National Park Management and Local Communities’ Perceptions Based on Survey, a Case of Nyungwe National Park, Rwanda

A sustainable management of national park requires collaboration between park staff, NGOs, local organizations and stakeholders, and government intervention. This collaboration promotes community-based welfare and inspires a sense of responsibility, thus promoting more benefits than conflicts. A survey administered to residents surrounding Nyungwe National Park was used to evaluate the relationship between Nyungwe National Park management and local communities. The residents acknowledged a positive attitude towards participating in conservation organizations where there was involvement, while a negative response revealed weak community mobilization. The community’s opinions about protection and tourism progression noted weak conflict resolution, but a positive attitude towards tourism activities in the area since they believed employment was likely as a result. In addition, the residents asked for support from government investments and stakeholders to develop the local private sector, and asked to be involved during the planning process. Approaches including the design of coordination mechanisms and integrated conservation and developments projects are suggested to promote a management structure leading to community involvement in conservation and tourism activities. This will increase visitor numbers and contribute to economic development not only in the region but also in the whole country. Empirical studies along with the factors shaping tourism and conservation activities should be considered as the basis for sustainable decision and policy making for sustainable management, and will contribute to government, stakeholders and park manager collaborations at Nyungwe national park.

Optimal Operation of Electric Vehicles and Distributed Generation Resources in Smart Grid Considering Load Management

Technology advancement and the global tendency to use renewable energy in distributed generation units in the distribution network have been proposed as sources of energy supply.Despite the complexity of their protection,as well as the operation of distributed generation resources in the distribution network,factors such as improving reliability,increasing production capacity of the distribution network,stabilizing the voltage of the distribution network,reducing peak clipping losses,as well as economic and environmental considerations,have expanded the influence of distributed generation(DG)resources in the distribution network.The location of DG sources and their capacity are the key factors in the effectiveness of distributed generation in the voltage stability of distribution systems.Nowadays,along with the scattered production sources of electric vehicles with the ability to connect to the network,due to having an energy storage system,they are known as valuable resources that can provide various services to the power system.These vehicles can empower the grid or be used as a storage supply source when parked and connected to the grid.This paper introduces and studies a two-stage planning framework for the concurrent management of many electric vehicles and distributed generation resources with private ownership.In the first stage,the aim is to increase the profit of electric vehicles and distributed generation sources;finally,the purpose is to reduce operating costs.The proposed scheduling framework is tested on a distribution network connected to bus 5 of the RBTS sample network.Besides distributed generation sources and electric vehicles,we integrate time-consistent load management into the system.Due to distributed generation sources such as photovoltaic systems and wind turbines and the studied design in the modeling,we use the Taguchi TOAT algorithm to generate and reduce the scenario to ensure the uncertainty in renewable energy.MATLAB software is used to solve the problem and select the optimal answer.

基于牵引网电压和空载电压的多储能系统区间能量管理策略

近年来,随着“双碳”政策的推动,储能技术在城市轨道交通中的应用愈发广泛,呈现出点到线的发展趋势。当一条线路中有多站安装储能装置时,想要进一步提升储能系统的节能效果,必须要解决不同站储能装置的充放电策略个性化设计,以及多储能间协调控制这两个问题。因此,该文提出一种基于实时牵引网电压和空载电压的多储能系统区间能量管理策略。该策略基于多个牵引变电站的空载电压和牵引网电压,对能量管理区间内的列车状态和列车剩余功率进行辨识,基于此计算区间内储能装置的充放电阈值基准值初值及基准值变化的斜率。为进一步提升节能和稳压效果,该策略基于充放电周期、牵引网电压超限频次及储能系统的荷电状态(SOC)等参数,对基准值及其更新斜率进行实时校正。该文在北京地铁的实际线路中进行了验证,结果表明,相较于基于本站空载电压的能量管理策略,提出的策略在降低系统能耗和稳定牵引网电压方面都具有显著的改善效果。

养老保险全国统筹下的委托代理问题:经办机构垂直管理是不是破解之匙?

2022年我国职工养老保险正式实现全国统筹。然而,受制于现行“央地共管”社会保障模式,全国统筹易引发中央与地方政府间委托代理问题,不利于全国统筹目标的顺利实现。在此背景下,经办机构全国垂直管理能否成功化解委托代理问题?利用省级改革近似模拟全国改革,构建计量和精算模型发现:第一,职工养老保险省级统筹造成有效费率降低2.40%,若同时辅以经办机构省级垂直管理,有效费率会提高2.90%;第二,异质性检验结果表明,经办机构实现垂直管理在老龄化程度高和国有经济占比低的地区效果更好;第三,从养老保险经办流程看,统筹层次提高将导致地方政府在参保登记环节放松监管以创造招商引资优势,实现垂直管理后此类寻租行为将得到有效改善;第四,未实现全国统筹下2023—2050年间政府养老保险累计支出达到718.02万亿,实现全国统筹后财政支出规模增加19.06%,若辅以经办机构全国垂直管理,政府养老保险支出规模将下降23.08%。综上,为确保全国统筹政策效应的有效释放,研究认为应采取渐进式改革路径,即首先建立起市级政府对县区级政府垂直管理的经办体系,然后做实养老保险经办机构省级垂直管理,最后再构建起从中央到地方的垂直管理体系,以期推动职工养老保险制度高质量发展。

基于多目标协调的混合储能功率自适应分配方法

混合储能具有良好的功率可控特性,在孤岛微网中常被用作功率缓冲器,补偿分布式电源和负荷多变的功率潮流.围绕储能的功率响应问题,本文设计了混合储能的功率控制方案,并提出了一种基于多目标协调的子单元功率自适应分配方法.首先基于对母线功率供求平衡关系的分析,设计了主从并联型储能功率控制方案.其次利用积分器的“时空调零”特性,实现了子单元的功率自主分配;基于此,考虑了不同荷电状态(SOC)下储能最大充放电功率的差异,设计了子单元的SOC分层管理和多目标功率协调策略.仿真结果表明,所提策略实现的功率分配效果满足子单元的功率响应特性;随着超级电容SOCscn偏移加深,所提策略对SOCscn的优化能力越强,初始SOCscn为97%时能提高10.10%的优化性能,这保障了超级电容作为电压源的功率输出能力;所提策略降低了超级电容常态下的蓄电池的输出深度,蓄电池的最大功率深度降低了46.70%,这提高了蓄电池的使用寿命.

国债管理:财政政策与货币政策协调配合的关键点

国债兼具财政和金融功能,是财政政策与货币政策互动最为频繁活跃的领域,而货币政策的立场和操作也会直接影响赤字融资的来源与成本。因此,国债管理是两大政策协调配合的关键切入点。鉴于财政政策与货币政策配合的国际经验,针对我国政策协调配合中面临的挑战,我国应根据经济形势适时调整宏观政策调控机制;推动央行开展公开市场买卖国债;稳步推进国债市场的国际化建设;完善债务约束机制,科学设置债务上限;优化国库现金与央行流动性管理;积极发挥财政部在债务管理与国债市场建设中的主导作用,建立统一高效的政府债券市场;协同健全国债收益率曲线,共同推动曲线深入应用;进一步加强以国债为基础的金融市场流动性机制安排;在更高层面确立财政政策与货币政策的协调机制;保持两大政策部门更为畅通的信息交流。

技术进步能有效促进粮食安全与农民增收双目标实现吗?——来自全国省级面板数据的经验证据

技术进步能显著提高粮食安全与农民增收双目标实现的有效性。论文基于2002—2022年全国31省的面板数据,通过耦合协调度模型、DEA-Malmquist指数模型及面板数据双向固定效应模型等进行实证分析。研究表明:技术进步能明显提高粮食安全与农民收入一致性水平,其中,技术变化对粮食安全与农民收入一致性水平的影响更为显著,该结论在经过一系列稳健性检验后依旧成立。在经济发展水平相对落后的西部地区以及地形更为崎岖的丘陵地区,技术进步对粮食安全与农民收入一致性水平的促进作用更强。此外,技术进步可以通过促进农业适度经营规模水平提升进而间接作用于粮食安全与农民增收双目标的实现。以此为基础,论文提出了相应的政策建议,以充分发挥技术进步对粮食安全与农民增收双目标实现的促进作用。

党的职能部门统一归口协调管理的党内法规制度完善

归口协调管理是中国特色社会主义政治制度下,执政党对政府和其他政权组织、社会组织的领导与分类管理相结合的分类治理机制。党的职能部门统一归口协调管理作为党的十八大以来党和国家机构改革的重大制度举措,是发挥好党总揽全局、协调各方领导核心作用的重要内容之一。现行党内法规体系中并未将归口管理列为正式制度单独予以规定,归口管理作为新时代具有创制意义的党政机构改革模式,尚处于发展期和磨合期,仍然需要结合改革实践不断调试、完善与发展。其不仅涉及党的组织对政府组织和其他政权组织、社会组织的多重领导关系和管理关系,更涉及党的组织工作层次的合理划分以及工作机制的分类推进等党和国家机构深化改革中的一些深层次问题,仍需要在理论上和实践中不断探索、逐步完善。现阶段,党的职能部门归口管理虽不具备通过制定专门党内法规进行统一规范的立规条件,但应当以《中国共产党工作机关条例》的修订工作为契机,在明确党的职能部门归口管理制度内涵的基础上,本着规范主体、规范行为的原则,完善归口管理的一般性原则规定,为其制度的体系化完善打好坚实基础。
