摘要： 引子2018年6月5日凌晨2点（加拿大当地时间2018年6月4日14点）左右,一辆载有36名中国旅客的旅游大巴在加拿大安大略省Prescott附近的401号高速公路上发生严重车祸,造成24人受伤,4人伤势严重,2人死亡。据了解,这辆旅游大巴属于Union Tour Express公司,是一家在美国注册的华人旅行社。它计划从美国华盛顿出发,前往加拿大多伦多进行为期10天的旅行,乘客全部都是中国人,一共37名,其中1名导游。车上36名中国游客都不怎么会说英语,在外交流只能靠唯一会说英语的导游。

摘要： A changing mosaic of natural vegetation and human land uses has evolved within and around the Flint River Watershed (FRW) in Alabama and Tennessee over the past several decades. To determine the cause of change and linkage between human activities and environmental change can prove problematic. Subsequently, there is a need to produce projections of future environments based on planning instruments and socio-economic parameters. Scenarios of potential future land use land cover (LULC) change are required in order to better manage potential impacts on many environmental issues. This study creates future scenarios for the year 2030 from baseline land use of 2001, relative to three projected land use scenarios which include differences related to conservation, planning, and development. The future growth scenarios were created using the ArcGIS tool, Prescott Spatial Growth Model (PSGM). The model allows users to build different future growth scenarios based on socio-economic projections such as population, employment and other controlling factors. The simulation results indicate that LULC changes associated with future urbanization can increase by ~23% - 43% within the FRW, which will lead to significant environmental issues if not managed properly. The overall analysis and model results demonstrate the ability of future growth scenarios to explore and evaluate options for a future environment. Spatial modeling and analysis tools, such as PSGM, provide a powerful approach to evaluate potential impacts of LULC change in the future and should be used to manage urbanization in areas with more intense development.

摘要： Flint River watershed is located in northern Alabama and southern Tennessee, USA and is home to several species of rare, threatened, or endangered plants and animals in a rapidly urbanizing area. Dominant land uses are forest and agricultural, with row crops and livestock production as major farm enterprises. Soil and Water Assessment Tool (SWAT), a deterministic hydrologic model that can predict hydrologic conditions over various temporal and spatial scales, was used to simulate the hydrologic response of the watershed to land-use/land cover (LULC) change. Analysis between observed and predicted stream flow demonstrated that the initial SWAT model run requires calibration of stream parameters in order to give a more accurate output from the model. The calibration was performed with sequential uncertainty fitting, ver. 2 (SUFI-2) in the SWAT Calibration Uncertainty Program. After calibration, stream sediment yield values were compared by sub-basin between a current (2001) and three future (2030) land use scenarios, in order to identify areas in the watershed that were the most susceptible to increased sediment yield in the future. The future growth scenarios (smart, plan and sprawl) were created using the ArcGIS extension, Prescott Spatial Growth Model. Sub-basins with the greatest sensitivity for larger sediment yields were identified and prioritized for conservation efforts.

摘要： 经济学和经济史分别从理论和经验告诉我们，动态小一致性足经济政策有效性的致命问题。所谓动态不一致性,指的是决策者行为与自身承诺的背离，最终导致各方均陷入行为的机会主义状态和较蔗的均衡水平。有关理论的现代版本在经济学关于宏观调控的方法论中多有论及，代表人物如Kydland和Prescott、Goodhart等。

摘要： 人物介绍：约翰·普雷斯科特：（John Leslie Prescott,Baron Prescott of Kingston-upon-Hull,1938年5月31日-）,英国工党政治家,自1997年至2007年任英国副首相前,现仍担任下议院议员。2006年2月23日,他作为英国第一副首相,代表英国政府到中国为宁波诺丁汉大学的校园落成揭牌、为校园内的可持续发展研究中心大楼奠基。

摘要： ——英国前首相Tony Blair在其自传A Joumeyqb提到前副首相John Prescott饮茶时习惯将茶杯和茶碟放在肚子上。查尔斯王子看到后非常诧异，问Blair，这是某种姿势呢，还是表示敌意或党派仇恨．还是别的什么？Blair说，他只是喜欢那样喝茶而已，没别的意思。

摘要： 一、货币政策时间不一致性的基本思想 以基德兰和普雷斯科特（Kydland and Prescott，1977）的开创性研究为发端，人们开始注意到中央银行可信度以及对政策事先承诺的能力等问题。如果没有对采取特定政策措施事先做出保证，那么，中央银行可能会产生不按原来计划和宣示行事的动机，这就导致了货币政策的“时间不一致性”或“动态不一致性”。所谓时间不一致性是指：在t期为t＋i期计划的行动方案，在t＋i期到来时，实施该行动方案不再是最优的。

摘要： 焦耳定律是基础物理教学的重要内容之一，在一些中学物理教材中，往往会涉及焦耳（James Prescott Joule，1818-1889）的生平和科学贡献[1-2]．本文依据焦耳的论文和一些研究文献，详细介绍了焦耳定律的建立背景，以及提出焦耳定律的实验研究过程，并对焦耳的研究特点和成功因素作了一些初步分析，希望为焦耳定律的教学提供物理学史方面的参考资料．
