World Food Policy, Volume 12, Issue 2, November 2026.ABSTRACT Household food expenditure continues to be a key factor in ensuring the realization of the Human Right to Adequate Food. Particularly in Brazil, access to food can be limited by economic constraints in vulnerable families, especially among farming families, who have been more vulnerable to food insecurity in recent years in the country.

Gaoya dianqi, 2018 套管是电力变压器的重要附件,其安全稳定运行至关重要。为此,常采用在线监测技术对其运行状态进行实时监测。在电网内部,变压器套管在线监测系统已有一定应用。然而,监测数据不仅取决于套管自身绝缘性能,而且受温度、湿度和系统运行电压等环境因素影响,且当前各套管监测厂家推荐的预警策略各异,难以满足应用要求。因此研究适宜的在线监测预警策略至关重要;文中对广东电网在运变压器套管的介损值历史监测数据进行了统计分析。研究发现变压器套管在线监测应用过程中会出现短时性、间歇性的数据异常,异常率接近1%,导致监测系统告警 ...

Gaoya dianqi震害调查表明，强震作用下变电站有较高的易损性，对震后的快速修复及抢险救灾工作产生极大的影响。以220 kV变电站为分析案例，文中进行了系统震害的抽样模拟，并采用混合整数线性规划（MILP）生成了最优修复决策序列。利用MILP的决策结果，本研究训练了人工神经网络（ANN）模型，提出了基于该模型的修复策略，适用于缺乏高性能计算条件的场景。其次，分析了变电站震后各类组件的修复优先级，可实现灾后故障位置未知时的修复决策。最后，基于3种不同的改造策略对变电站进行了抗震韧性改造。结果表明，与MILP策略相比 ...

World Food Policy, Volume 12, Issue 2, November 2026.ABSTRACT Prevailing levels of hunger, malnutrition, and food insecurity—driven by conflict, global economic crises, and ecological destruction—are threatening fulfillment of the right to adequate food. The integration of human rights in food systems policies can address these challenges; however, progress in the adoption of human rights–based ...
