Study on the Optimization of the Seawater Environmental Monitoring Network in the Bay Based on Kriging and GIS: A Case Study from Quanzhou Bay, Fujian Province [PDF]
, 2015 海湾生态系统是一种重要海洋生态系统类型，通常具有独特的生态环境和高价值的各类资源。同时，其优越的自然条件、区位条件以及多样、丰富的资源，促使海湾周边城市社会经济发展快速，人口密度增大。但是，海湾作为半封闭海域，海水交换能力与自净能力有限，易受径流沉降与陆源污染物输入的影响，其生态环境较为脆弱。因此，亟需基于高效、准确的海洋环境监测评价以实施环境监督管理的措施。目前，我国海洋环境监测工作普遍存在监测目的不明确、环境信息不完整以及监测计划针对性弱等问题，导致现已开展的海洋环境监测与评价无法衔接 ...

The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Experimental research progress of public management——based on the literature analysis of 2000-2015 [PDF]
, 2016 20世纪80年代后期开始，一场影响巨大的行政改革席卷发达国家和发展中国家。新公共管理运动是关于公共管理范式的一次重大变革，这种变革不仅体现在以公共选择理论、制度经济学理论、交易成本理论等为基础的理论变革，更体现在方法论上的变革。公共管理是一个方法选择多样的学科，然而实验法作为探索问题的传统途径，不管是与其他社会科学的实验方法应用比较，还是与公共管理学科中其他经验研究方法的应用比较，公共管理实验研究少之又少。 得力于一些公共管理学者的不懈努力，近年来，公共管理实验研究已经取得了一些进步。但无论何种学科 ...

A Research on Short-term Export Credit Insurance Marketing Strategy of SINOSURE [PDF]
, 2016 随着国际经济形势复杂性和不确定性因素不断增加，出口企业在国际贸易中的风险也随之增加。为了降低国际交易中的收汇风险或获得融资，出口企业对出口信保的需求增加。在此背景下，中国信保作为我国唯一政策性信用保险机构的作用变得尤为重要。但是，随着短期出口信用险业务逐步市场化，商业性保险机构可以开展短期出口信用险业务，必然对其短期信用险业务产生影响。基于此，论文围绕中国信保短期出口信用险营销策略进行深入研究，在分析外部环境和自身优势和劣势的基础上，制定可行的营销组合策略，旨在提高中国信保短期出口信用险的竞争力 ...

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico
Conservation Biology, EarlyView.Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...
