高变异Y染色体短串联重复片段检验体系的建立及对北方汉族群体调查
Zhongshan Daxue xuebao. Yixue kexue ban, 2021 目的建立一套五色荧光复合扩增体系，并调查中国北方汉族遗传多态性和父子家系突变情况。方法根据文献筛查出在中国某一群体中突变率为高变异和快速变异的Y-STR基因座，建立一套五色荧光Y-STR复合扩增体系，计算在500个北方汉族无关男性个体中的基因多样性，观察每个样本的Y-STR单倍型，并对中国北方汉族500个父子对进行检测，统计父子间的突变情况。结果成功构建了包含21个Y-STR基因座复合扩增检验体系，在北方汉族群体中基因多态性在0.402 3～0.990 4之间，500个无关个体中未发现有相同的单倍型 ...

Psychometric framework for coexistence with large carnivores
Conservation Biology, EarlyView.Abstract Human–carnivore coexistence is essential for biodiversity conservation, yet measuring the attitudes and behaviors that support it remains methodologically challenging. We developed psychometric scales to assess willingness to coexist with carnivores and the underlying beliefs of this coexistence through an iterative expert elicitation process ...

Genomics‐informed management of ex situ populations
Conservation Biology, EarlyView.Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.

International Journal of Applied Linguistics, EarlyView.ABSTRACT Multilingual students in Anglophone universities often operate in survival mode. While translanguaging supports learning, critical gaps remain in understanding how translanguaging pedagogies transform and sustain motivation in English‐dominant contexts.

Coalition Breakdown and Subsystem Exit
Policy Studies Journal, EarlyView.ABSTRACT Why actors choose to work together (or not) to advance policy has been the central area of inquiry within the Advocacy Coalition Framework (ACF). Existing research has mainly emphasized the pathway towards coalition formation and evolution, underscoring the stable patterns of allies and opponents observable in policy processes over a decade or

The Making of the Right to Food: Tracing Food Policy Conflict and Negotiated Outcomes in Colombia
World Food Policy, Volume 12, Issue 2, November 2026.ABSTRACT The 2016 Peace Agreement between the Colombian Government and the FARC guerrilla group marked a historic step toward ending more than five decades of armed conflict. It also reshaped national food policy with lasting implications. During the negotiations, deep ideological divisions emerged between food sovereignty and food security, and these ...
