Jaguar Densities and Land Cover Change in a Multi‐Use Landscape: A 10‐Year Comparison in the Colombian Llanos 美洲豹种群密度与复合用地景观下的土地覆被变化:哥伦比亚亚诺斯地区10年比较研究

open access: yesWildlife Letters, EarlyView.
We used spatially explicit capture‐recapture to estimate jaguar densities in a private reserve in the Colombian Llanos and quantified land cover change in and around the reserve from 2014 to 2024. Densities increased 22% since 2014, while disturbed land cover increased by 39%–54% around the reserve depending on buffer distance. Our study indicates that

Using Harvest Data to Assess Factors Influencing Regional Population Declines of Muskrats (Ondatra zibethicus) 利用捕获数据评估影响麝鼠 (Ondatra zibethicus) 区域种群数量下降的相关因素

open access: yesWildlife Letters, EarlyView.
Reported annual per‐capita harvest of muskrats (PCHM) decreased as wetland complexity (total number of wetland patches) decreased in 13 state and federal wetland areas in the Midwest, USA. Our results support the hypothesis that regional‐scale declines in the abundance of muskrats are likely associated with the losses to wetland habitats throughout the

Costco(好市多)的經營管理策略 [PDF]

open access: yes, 2009
根據先進國家的演進歷程來看,當國民所得低於一千美元的時候,傳統的零售店盛行;當國民所得超過一千美元的時候,百貨公司開始興盛成長;當國民所得超過三千美元的時候,超級市場便蓬勃發展;當國民所得超過六千美元的時候,便利商店開始大量增加;當國民所得正式突破一萬美元的時候,量販店則陸續導入市場。現階段國內量販店之間競爭激烈,所銷售的商品及所提供的服務在功能上來說差異不大。剛上市的新產品或服務只能擁有短暫的競爭優勢,今日的優勢商品或服務很快便會被同業模仿,競爭優勢降低甚至消失殆盡。所以 ...

Reconstructing Old Chinese *‐ts Using Han‐Time Material

open access: yesTransactions of the Philological Society, EarlyView.
Abstract Baxter & Sagart (2014b) reconstruct *‐Vt‐s on the basis of Middle Chinese reflexes in ‐jH (from some OC *‐s) coupled with either etymological or graphic connections to words in Middle Chinese ‐t. This approach, while perfectly sound, can suffer from lack of etymological or graphic data, leading to missed reconstructions. Since Old Chinese *‐ts

PARTY‐STATE URBANISM: Coevolution of Local State Capacity and Strategic Alliances in Shenzhen

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract What is distinct about Chinese urban governance? Classic theories predict that when the central state retreats from resource allocation, capacity‐strained local governments must form alliances with non‐state actors, thereby diluting state power. In China, however, state power remains dominant despite decentralization.

Method for two-sided matching considering multi-style aspiration of agents based on score information(得分信息下考虑多种形式主体期望的双边匹配方法)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2017
针对得分信息下带有多种形式主体期望的双边匹配问题,考虑主体的心理行为因素,提出了 一种基于前景理论的双边匹配方法.首先,以主体期望为参照点将双边主体给出的得分信息转化为相对于参照点的收益和损失;然后,考虑主体对待收益和损失不同的风险态度,依据前景理论计算每个主体的前景值,在此基础上,建立双边匹配多目标优化模型,使用极大极小法求解该模型,获得双边匹配方案;最后,通过一个算例验证了该方法的可行性和有效性.
