Abstract The Citizen Income (Reddito di cittadinanza—RdC) is the most extensive program to fight poverty ever adopted in Italy. RdC is a Minimum Income Scheme that grants a cash amount to beneficiaries but obliges some specific groups to participate in active measures and in social inclusion programs.

Abstract Tibetan Buddhist monasteries are widely distributed throughout the Qinghai–Tibet Plateau and are significant locations for human–wildlife coexistence. Given the significance of their historical and contemporary social influence, it is crucial to ascertain whether there exists a non‐negligible correlation between these monasteries and their ...

Understanding consumers to inform market interventions for Singapore's shark fin trade
Abstract Sharks, rays and their cartilaginous relatives (Class Chondrichthyes, herein ‘sharks’) are among the world's most threatened species groups, primarily due to overfishing, which in turn is driven by complex market forces including demand for fins.

“God was with me”: A qualitative study of Christian meaning‐making among refugees
Abstract In this consensual qualitative research study, we investigated the role of refugees’ Christian faith in meaning‐making coping. High percentages of religiosity in refugee populations support the need to understand the role of religion in their coping processes.

目前偏磁式消弧线圈的研究是将励磁绕组电源简化为恒流源模型,得出消弧线圈的工作特性,但现场实践表明,消弧线圈实际工况中的偶次谐波电流分量已经大到不可以忽略,因此忽略偶次谐波电流而将励磁电流简化为恒流源在一定程度上影响了分析结果的准确度。针对此种研究方法的缺陷,考虑偶次谐波电流的实际影响,笔者提出了基于自由偶次谐波原理研究偏磁式消弧线圈工作特性的新方法,通过数学建模,得到了消弧线圈的调节特性和伏安特性。研究结果表明,基于自由偶次谐波原理的研究方法能够反映实际工况 ...
