财务契约与和谐财务

对于财务学而言，财务契约与和谐财务都是重要概念，需要深入研究。从本质上看财务契约与和谐财务既有联系，又有不同，需要我们在更高层次上将二者融合。     

Satellite and ground detection of very dense smoke clouds produced on the islands of the Paraná river delta that affected a large region in Central Argentina

Intense fires were produced on the Paraná river delta islands, Argentina, during most part of 2008, by a combination of an exceptionally dry period and the farmers’ use of a fire land-cleaning technique. In April 2008, those fires significantly affected the nearby regions and their inhabitants, from Rosario city to Buenos Aires mega-city. In this work we present satellite as well as ground Aerosol Optical Depth (AOD) at 550 nm data obtained during the propagation of pollution clouds to the central zone of Argentina. The highest value (1.18) was registered at Buenos Aires by atmospheric remote sensing, using the satellite instrument MODIS/Terra on April 18th 2008 at 10:35 local time (= UT − 3 h). On the same day, ground air quality detectors also measured in this city the highest Total Suspended Particle (TSP) value of the month, 2.02 mg/m³. The AOD(550) daily variation at Rosario Astronomical Observatory, which is located near the Paraná riverside, was derived by combining solar ultraviolet erythemal irradiance data (measured with a YES biometre) with model calculations. On April 25th 2008, from 12:00 to 15:30 local time, a rather high and constant AOD(550) value was registered, with a mean value of (0.90 ± 0.21). Cities located on the side of the Rosario–Buenos Aires highway (San Nicolás, Baradero and San Pedro) were also affected, showing a mean AOD(550) between the Rosario and Buenos Aires values. The particulate matter was collected with gridded samplers placed on the Paraná river islands as well as at the Rosario Observatory. They were analysed with a Scanning Electron Microscope (SEM) and mainly showed a biological origin. Even if normally large particles travel small distances from the source, organic aerosol in the range of 40–100 μm and complex asymmetric structures were registered several kilometres away from the aerosol sources on the islands. Another event of intense UV index attenuation (98.6%) occurred on September 18th 2008, due to very dense smoke clouds that extended over the Rosario area for several hours. The clouds were driven away from the fires by East–northeast and East–southeast winds. The minimum value of this index measured around noon allows to derive a maximum AOD(550)_max = (3.65 ± 0.90) at 12:45 local time. Soot clouds extended over the Paraná river, transporting Burned Biomass Debris (BBD) that deposited on Rosario. In particular, burned leaves and small branches with dimensions of 1–20 cm were collected. The mean (BBD) particles deposited on the ground from 7:00 to 19:00 local time were (0.92 ± 0.20) BBD/(m² h).

高职创新教育管理中若干问题探讨

创新是一个民族的灵魂,教育领域中的创新管理在创新型国家建设中至关重要,高职教育作为高等教育的重要组成部分,因其培养目标的特殊性更应该关注创新问题。创新教育管理是高职教育管理的重要方面,文章从高职教育创新管理的基本认识、目标设立、体系建设方面进行了探讨。     

排列图在实验室质量管理中的应用

利用排列图法对实验室2005至2009年的内部审核不符合项进行了分析。实验室内部审核不符合项主要集中在记录的控制、设备的管理、测试方法及确认、文件的控制四个方面,不符合项产生的根本原因是人为因素。运用排列图法分析实验室质量问题的产生原因简便、可靠、有效。

基于Volterra捕食模型的飞行流量动态调配

为缓解当前飞行流量需求与空域资源限制间的矛盾,改善静态流量分配方式下航路飞行流量限制问题,提出飞行流量动态调配概念并建立动态调配模型及算法.首先根据Volterra捕食模型的思想,以航路负荷值大小为依据划分种群,依据航路飞行流量的调配速度建立飞行流量的动态调配模型,然后提出实时流量动态调配算法,按时段周期性对航路的飞行流量重新划分种群,并根据航路当前状况对飞行流量进行动态调配.最后运用Matlab软件进行算例分析,结果表明了模型及算法的有效性,可以很好地应用于飞行流量的动态调配研究中.
