不同降雨强度下农地的产流产沙研究

采用人工模拟降雨的方法，分设5种不同的降雨强度研究半干旱区农地的产流产沙特征，结果表明：农地径流量、侵蚀模数随雨强的增加而增加，并与降雨强度呈指数函数或幂函数，小麦地和裸地径流量平均值分别为39．1mm和50．1mm，径流系数最高达60％以上，裸地与小麦地的侵蚀模数之比最大达25倍。

20世纪二三十年代广东的商品包装设计

20世纪二三十年代,广东相对稳定的商业环境及政策推动了广东民族工商业的发展与民族包装工业的兴起,商品促销和贸易需求促进了商品包装设计的快速发展。在西方现代主义思潮的不断冲击下,广东的商品包装设计由传统美术风格很快过渡到了与现代设计接轨并初具雏形,具体表现为在造型上中规中矩,图案上以写实的具象图案为主,字体上中西结合,色彩上喜用纯色,版式上对称均衡,整体呈现华洋共处、中西结合的风格特征。从政治、经济、技术、文化等多角度解读这一时期广东的商品包装设计特征,从而挖掘出属于这个时代的包装印记,以期对当代包装设计有所启迪。

Forecasting of electricity price through a functional prediction of sale and purchase curves

This work proposes a new approach for the prediction of the electricity price based on forecasting aggregated purchase and sale curves. The basic idea is to model the hourly purchase and the sale curves, to predict them and to find the intersection of the predicted curves in order to obtain the predicted equilibrium market price and volume. Modeling and forecasting of purchase and sale curves is performed by means of functional data analysis methods. More specifically, parametric (FAR) and nonparametric (NPFAR) functional autoregressive models are considered and compared to some benchmarks. An appealing feature of the functional approach is that, unlike other methods, it provides insights into the sale and purchase mechanism connected with the price and demand formation process and can therefore be used for the optimization of bidding strategies. An application to the Italian electricity market (IPEX) is also provided, showing that NPFAR models lead to a statistically significant improvement in the forecasting accuracy.     

Forecasting of dependence,market, and investment risks of a global index portfolio

This paper undertakes an in-sample and rolling-window comparative analysis of dependence, market, and portfolio investment risks on a 10-year global index portfolio of developed, emerging, and commodity markets. We draw our empirical results by fitting vine copulas (e.g., r-vines, c-vines, d-vines), IGARCH(1,1) RiskMetrics value-at-risk (VaR), and portfolio optimization methods based on risk measures such as the variance, conditional value-at-risk, conditional drawdown-at-risk, minimizing regret (Minimax), and mean absolute deviation. The empirical results indicate that all international indices tend to correlate strongly in the negative tail of the return distribution; however, emerging markets, relative to developed and commodity markets, exhibit greater dependence, market, and portfolio investment risks. The portfolio optimization shows a clear preference towards the gold commodity for investment, while Japan and Canada are found to have the highest and lowest market risk, respectively. The vine copula analysis identifies symmetry in the dependence dynamics of the global index portfolio modeled. Large VaR diversification benefits are produced at the 95% and 99% confidence levels by the modeled international index portfolio. The empirical results may appeal to international portfolio investors and risk managers for advanced portfolio management, hedging, and risk forecasting.     

论和谐精神

古老的中华文明历经几千年而不衰,源于中华民族强大的自我再生能力,而这一强大自我再生能力的终极动力源则是以"贵和"、"中庸"、"仁厚"、"适度"为主要内涵的和谐理念.正是对全方位、多层面和谐的崇尚,使中华民族形成了自己独有的和谐哲学与和谐精神.在悠悠历史长河中,作为中华民族基本民族精神的和谐精神成了黏和中华民族的强大精神动力.儒家思想实际上是对和谐精神的集中阐释.和谐理念表达了人们对所有人类和非人类存在最佳存在状态和发展趋向的期盼,事实上成了真善美的最恰当表述.在人类面临生存困境的严峻形势下,以和谐思维弘扬和再造和谐精神,实现真正意义上的和谐发展,是我们无法回避的问题.
