国际橄榄理事会的定位和使命及相关标准（网络首发、推荐阅读）

The International Olive Council(IOC) is an international intergovernmental organization dedicated to olive oil and table olives, aiming at modernizing olive production, coordinating olive policies, improving the regulation of international trade, defending the quality of the olive sector and promoting olive oil and table olives to increase their consumption. The IOC grants recognition of laboratories and tasting panels in annual trials when they meet the conditions given in the decisions adopting the IOC certificate for laboratories for the physico–chemical testing of olive oil and laboratories for the sensory analysis of virgin olive oils. The IOC establishes analysis methods applying to olive oils and olive pomace oils for purity, quality and organoleptic assessment. The IOC elaborates guides of storage conditions for olive oils and olive pomace oils, of managing virgin olive oil tasting panels and of sensory testing laboratories. In future works, the IOC includes activities to identify analytical criteria for detecting fraud and guaranteeing the quality of olive oils and olive pomace oils.     

自然资源资产负债表的编制难点分析

随着近几年我国经济社会快速发展,经济发展对自然环境产生的较大影响,因而造成我国自然资源过度损耗,生态环境遭受严重破坏。十八届三中全会首次提出编制自然资源资产负债表,目的就在于创新我国自然资源管理体制,给我国环境治理和生态修复提供一个更好的解决办法和途径。因此,我国各个领域的专家学者从多方位多角度对自然资源资产负债表的编制问题展开探索,在研究过程中也产生了许多难题。本文根据对目前自然资源资产负债表现有文献的分析,简要分析当前自然资源资产负债表编制工作的一些难题,并对未来编制工作提出几点意见。     

智融标识网络基础研究

近10年我国传统饮料酒白酒和黄酒品质安全研究现状与展望

总体上说,我国白酒和黄酒的安全性指标研究起步较晚,特别是白酒和黄酒中氨基甲酸乙酯(ethyl carbamate, EC)的研究,大部分研究更多关注检测方法的开发,针对可能超过限量的指标的消减技术研究较少,而从源头和过程控制角度进行消减的技术研究显得更为稀少。建议尽快制订相关标准和/或控制指南,加大基础性研究和控制技术研究力度,为我国白酒和黄酒品质安全研究提出建设性建议。本文重点回顾了近10年来我国传统饮料酒白酒、黄酒中氨基甲酸乙酯、氰化物、生物胺、真菌毒素和塑化剂等安全风险因子的研究现状,包括检测方法、产品现状、过程变化、产生机制或形成途径,以及消减技术,对现有饮料酒白酒和黄酒品质安全研究的问题与挑战进行了分析。     

Future changes in wind energy resource over the Northwest Passage based on the CMIP6 climate projections

The preferential use of renewable energy sources such as wind power has been proposed as one of the most effective strategies in reducing greenhouse gas emissions in the energy sector. However, wind energy resources are vulnerable to climate change, which might have a huge impact on the area under consideration. In this research, we used the wind speed data obtained from the seven coupled global climate models in the Coupled Model Intercomparison Project Phase 6 (CMIP6) to quantitatively analyze the differences in wind energy resource (WER) between the future and the historical period, geared toward understanding the impact of climate change on wind energy sources. Relevant results show that the future WER would decreases below 20% in the region south of the Northwest Passage, while would significantly increase in the north region of 72°N (specifically in the Beaufort Sea). Further, reports predict that by the end of the 21st century, if no interventions are made to mitigate greenhouse gas emissions, the northern region's WER would increase even more with some grid points exceeding 30% and have a significant growth trend, but at the same time the intra‐annual variability in these region would also increase significantly with some grid points exceeding 140% of that in the historical period. Moreover, the maximum wind speed values would encounter a noteworthy increase of up to 20%, which will bring great challenge to the development of wind energy in these region. Although the current models still have great uncertainties in the future climate prediction, our work still has certain guiding significance for the future development of wind energy over the Northwest Passage.     

U.S. regulatory perspectives on the back end of the fuel cycle: EUROSAFE 2013 proceeding

For the United States Nuclear Regulatory Commission and the reactor licensees it regulates, there are a number of contemporary issues associated with the back end of the fuel cycle including, the agency's revision to its “Waste Confidence” decision and the path-forward for high-level waste disposal. Additionally, the 2012 Blue Ribbon Commission on America's Nuclear Future recommendations, the future of reprocessing, consolidated interim spent fuel storage, and maintaining technical competence within the NRC in challenging budgetary conditions are addressed. I conclude that there is confidence in the feasibility of safe storage of spent nuclear fuel following the licensed operational life of a reactor and any change in high-level waste policy will require Congressional action to amend the Nuclear Waste Policy Act.     

动力煤期货价格波动对我国煤炭经济影响研究*

采用中国煤炭价格指数、中国煤炭市场景气指数、中国煤炭市场预期指数和煤炭行业失业率作为我国煤炭经济发展的代表变量,选取2013年9月～2018年7月之间的交易数据,构建VAR模型,研究了动力煤期货价格与中国煤炭价格指数、中国煤炭市场景气指数、中国煤炭市场预期指数和煤炭行业失业率之间的动态关系。格兰杰因果检验表明:国内动力煤期货价格是中国煤炭价格指数、中国煤炭市场景气指数、中国煤炭市场预期指数和煤炭行业失业率的格兰杰原因。脉冲响应和方差分解分析表明:动力煤期货价格波动会引起中国煤炭市场景气度同方向变动;滞后2阶的动力煤期货价格上涨会使得中国煤炭市场预期指数上升;滞后2阶动力煤期货价格上涨,失业率降低。长期来看,动力煤期货价格上涨会使得失业率降低,动力煤期货价格与我国煤炭经济发展之间呈现动态均衡关系。
