International Social Security Review, Volume 78, Issue 2-3, Page 145-171, April-September 2025.Abstract Public works programmes (PWPs) are pervasively used to tackle poverty and unemployment, and to build infrastructure and skills in low‐ and middle‐income countries. While their impacts on poverty, food security and labour outcomes have been widely documented, there is little research focusing on the role of PWPs in supporting household climate ...

Complicated grief and posttraumatic stress after loss and separation under terror conditions
Journal of Traumatic Stress, Volume 37, Issue 1, Page 154-165, February 2024.Abstract The lives of people in conflict areas are often characterized by the experience of traumatic events frequently accompanied by loss and separation. These can equally trigger symptoms of posttraumatic stress disorder (PTSD) and complicated grief (CG).

Jixie chuandong, 1997 本文分析了二级分流式双圆弧齿轮减速箱在冲击激励作用下的振动特性，并认为减速箱在对称冲击激励下的响应也是对称的，对不对称的冲击信号具有改正作用；冲击信号在减速箱系统阻尼的作用下，将很快衰减；较小的冲击只影响受冲击的构件及相邻构件 ...

Flirting with a basic income in Canada: Were the lessons worth the risk of popular backlash?
International Social Security Review, Volume 77, Issue 1-2, Page 67-83, January-June 2024.Abstract Canada responded to the COVID‐19 pandemic with a series of supports, including direct payments to workers displaced by public health measures. While not a true basic income, the experience highlighted a number of issues including challenges with implementation and intergovernmental relations that affected public opinion and must be dealt with ...

Gongye shui chuli基于豆制品废水冲击城镇污水处理系统导致出水污染物超标的实际问题，通过单周期瞬时废水冲击试验，探究了豆制品废水不同水质及水量对序批式间歇反应器（SBR）去除污染物效果的影响以及应急调控措施。结果表明，随水质冲击负荷增加，COD去除率先升高再下降，NH4+-N和TN去除率逐渐升高，水质冲击对TP去除效果影响较小。当冲击废水COD为370 mg/L时，出水NH4+-N和TN已不能满足《城镇污水处理厂污染物排放标准》（GB 18918—2002）一级A标准。随冲击水量增加 ...

750 kV罐式断路器合闸电阻操动冲击下应力分布数值模拟及影响因素分析
Gaoya dianqi, 2023 作为断路器中的关键组件，断路器合闸电阻在长期运行的过程中会承受巨大的机械和电流冲击，可能造成合闸电阻乃至断路器设备发生损坏。基于此，文中以典型LW13-800型罐式断路器为研究对象，建立了断路器合闸电阻数值仿真模型，计算了操动冲击力作用下合闸电阻的应力分布，分析了不同优化设计中的影响因素对合闸电阻应力的影响。研究结果表明：在同一电阻串上，最底端电阻片所受应力最大；合闸电阻串平均应力与操动冲击波形大致吻合；合闸电阻所受应力的平均值与操动冲击载荷呈正比例关系；在加装了纯铝过渡片后 ...
