Role of low‐impact‐factor journals in conservation implementation
Abstract Academic review, promotion, and tenure processes place a premium on frequent publication in high‐impact factor (IF) journals. However, conservation often relies on species‐specific information that is unlikely to have the broad appeal needed for high‐IF journals.

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 ...

蝉鸣声是耳鸣掩蔽治疗最常用的一种匹配声源,而目前数字化合成的蝉鸣声存在声音机械的问题.针对该问题,本文对蝉鸣合成数字化模型的激励源、声源模型和声道模型进行了优化:使用滤波成型波作为激励源;在声源信号中加入第二泛音分量;对声道模型的参数进行修改.最终合成的蝉鸣声在频谱丰富度和声音自然度得到了优化,对耳鸣的掩蔽治疗提供了技术参考.

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.

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 ...
