Calibration of the species threat abatement and restoration metric's threat abatement component in a Costa Rican landscape

open access: yesConservation Biology, EarlyView.
Abstract Achieving global conservation policy goals requires the ability to set and measure progress toward science‐based targets for biodiversity. The species threat abatement and restoration (STAR) metric was developed to enable actors to set science‐based targets for species.

Research on Risk Management of Intelligent Interactive Service System Project Procurement for A Government [PDF]

open access: yes, 2016
随着我国政府信息化建设的不断投入和加大,信息化项目采购已然成为政府采购的重要部分。政府信息化项目采购过程中涉及来自组织管理、采购人员、供应商、招标代理、评审委员会等这些方面诸多的风险,均会影响到项目建设的正常运行,不但会给政府带来经济、法律诸多的负面影响,甚至可能引发政府信息资源的安全危机。对信息化项目的采购风险进行识别与评估,提出相对应的风险管控措施对于提高政府采购绩效与提升政府信息化建设水平均具有较深的实际意义。 本论文首先对A政府智能互动服务系统项目的采购现状进行了分析概述 ...

Drivers of bat researchers’ intent to adopt field hygiene practices

open access: yesConservation Biology, EarlyView.
Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

Multi-modal fMRI study on brain structure and function in different factors induced rat chronic obstructive pulmonary disease [PDF]

open access: yes, 2015
慢性阻塞性肺病(chronicobstructivepulmonarydisease,COPD)脑结构和功能的异常在近些年受到了越来越多的研究关注。先前的神经影像学研究已经发现COPD伴随着白质完整性的损害和灰质的丢失,以及功能连接网络的异常。但是吸烟和非吸烟(如慢性肺部炎症)诱导的COPD病人脑部形态学和功能的异同,以及吸烟和感染因素的综合诱导是否加重了脑损害尚不清楚。致病因素和COPD病人脑部异常的特征性对应关系仍待进一步的探究 ...

基于三维程式的海底通道地铁项目施工风险识别 [PDF]

open access: yes, 2019
以盾构法整个掘进过程为对象,根据盾构法施工阶段的工艺步骤,结合以往经验及研究成果,运用盾构法施工风险识别的三维程式方法确定风险识别的范围和对象。通过WBS工作分解结构树和RBS风险分解结构树耦合,梳理盾构法施工基本工序单元与风险因素的对应关系,构建盾构法施工风险因素识别WBS-RBS结构矩阵,并据此建立过海通道盾构法施工风险因素矩阵,识别出过海通道盾构法施工关键风险因素。以期对过海通道盾构法项目施工风险管理提供理论依据和风险识别工具,为其他类似工程施工风险识别提供参考。中铁建投2016年科技重大计划 ...

Navigating the Algorithmic State: Public Values and Citizens' Preferences of AI‐Driven Public Service Delivery

open access: yesPublic Administration, EarlyView.
ABSTRACT As the public sector increasingly adopts AI‐powered automated decision systems (ADS), understanding how citizens experience and value ADS use in public decision‐making is both normatively and practically important. Therefore, we examine and compare the effects of seven attributes of public values on citizens' support for ADS adoption in two ...

A Risk Pre-Warning Model based on Financial Situation of Company Credit Clients of Bank of China Fujian Branch [PDF]

open access: yes, 2016
近年来,商业银行的不良余额及不良率大幅冒升,以中国银行福建省分行为例,2015年末中国银行福建省分行的不良余额已达38.14亿元,较2012年上涨了6倍有余,不良率也在2015年突破2.5%的大关,除此之外,逾期贷款也大幅攀升,资产质量形势不容乐观。除宏观经济环境的影响外,中国银行内部风险管理方面存在的弊端也对资产质量形势的恶化埋下隐患。风险管理人员过度依赖客户经理对授信风险进行识别,缺乏主动有效的工具和手段对授信客户的风险进行识别与预判,无法满足当前经济形势下风险管理的要求 ...

Arsenic Trioxide Induces T cell Apoptosis and Prolongs Islet Allograft Survival in Mice [PDF]

open access: yes, 2015
目的:作为一种最有潜力的I型糖尿病的治疗方法,胰岛移植目前已经应用于临床。然而,免疫因素特别是T细胞介导的移植物活性损伤与功能丧失是胰岛移植应用的一大障碍。一直以来,科学家们都在寻找适用于胰岛移植的新型免疫抑制剂。三氧化二砷是临床上治疗早幼粒细胞白血病的特效药,最近被证明能够抑制同种异体心脏移植排斥反应。在此基础上,本文研究了三氧化二砷对同种异体胰岛移植免疫排斥的抑制作用,以及三氧化二砷与雷帕霉素联合诱导免疫耐受的可能作用机制。 方法:我们首先检测了三氧化二砷对胰岛细胞的毒性作用 ...
