Twelve principles for successful governance of community‐based coastal marine restoration
Conservation Biology, EarlyView.Abstract Global agreements, such as the Global Biodiversity Framework, call for urgent, large‐scale action to halt biodiversity loss through a whole‐of‐society approach. Community‐based restoration can play a crucial role in achieving this goal, yet there remains limited understanding of what makes these projects effective and sustainable.

, 2008 本发明涉及分子标记方法，针对目前水稻育种中糯性基因不易识别的问题，本发明公开了一种通过特异性DNA片段识别水稻糯性基因的分子标记方法，以水稻糯性Wx基因的特异性片段为核心序列设计并合成引物，利用该引物对待测水稻样品的DNA进行PCR扩增，通过对扩增产物的检测，以扩增产物中是否含有全部或部分特异性片段来识别待测样品中是否含有水稻的糯性Wx基因，本方法能专一性的识别水稻糯性Wx基因，用于糯稻的新品种选育，可缩短糯稻新品种的育种周期 ...

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 ...

野生动物学报, 2018 蛇类养殖可以缓解野外资源的开发压力,起到积极的保护作用。但是从野外非法捕捉的蛇类以人工养殖之名混入合法市场的现象也十分常见。由于缺乏有效鉴别野生和人工饲养蛇类的方法,给监管市场和打击盗猎、非法贩卖等违法犯罪行为带来困难。本研究以养殖量和盗捕量较大的王锦蛇为例,建立了肝-头指数(Ilh)和肝-体指数(Ilb)两个肝脏指数来鉴别野生和人工饲养蛇类。利用这两个指标,采用Fisher's判别将已知来源的个体进行来源回判时,两个指标的正确判别率相同,在野生组均为96.9%,饲养组均为74.1%,整体正确率为86 ...

"fordi før så skreiv æ Å-G". En studie om andreklassingers valg av stavemåter.
, 2023 The purpose of this master's thesis has been to look at the choices students in Year 2 make when spelling words. The students participating in this research are in the transition between phonological and orthographic writing, and the study will focus on how these students adopt different spelling strategies. The assignment's data material is taken from

Learner‐Focused Strategy Instruction From the Teachers’ and the Learners’ Perspective
International Journal of Applied Linguistics, EarlyView.ABSTRACT Numerous large‐scale quantitative studies have been conducted to yield a macro‐level picture of the effectiveness of strategy instruction. However, little is understood about learners' actual processing of strategy instruction and interaction with the teachers delivering it.

血清-腹水白蛋白梯度及腹水胆固醇测定在鉴别 良恶性腹水中的意义
Zhongshan Daxue xuebao. Yixue kexue ban, 2002 【目的】探讨血清-腹水白蛋白梯度( SAAG) 、腹水血清白蛋白比值( A/S)、腹水胆固醇( CHOL)对良恶性腹水鉴别诊断的意义。 【方法】收集 53 例腹水患者的腹水及血清,按最终诊断分为四组,分别测定血清白蛋白、腹水白蛋白及腹水胆固醇,并将结果进行比较分析。 【结果】恶性腹水 SAAG( 14. 02±8. 29)g/L 与良性腹水 SAAG( 18. 78±7. 31)g/L 有显著性差异(P

仿生模式识别（拓扑模式识别）－－一种模式识别新模型的理论与应用
, 2002 本文提出了一种模式识别理论的新模型，它是基于“认识”事物而不是基于“区分”事物为目的。与传统以“最佳划分”为目标的统计模式识别相比，它更接近于人类“认识”事物的特性，故称为“仿生模式识别”。它的数学方法在于研究特征空间中样本集合的拓扑性质，故亦称作“拓扑模式识别”。“拓扑模式识别”的理论基点在于它确认了特征空间中同类样本的连续性（不能分裂成两个彼此不邻接的部分）特性。文中用“仿生模式识别”理论及其“高维空间复杂几何形体覆盖神经网络”识别方法，对地平面刚体目标全方位识别问题作了实验 ...
