设立中央政府投资基金 建立国土整治基地

中国西部地区尤其是大西北是我国三大经济带中经济发展相对落后的地域,由于历史和众多因素的制约,决定了开发西部是一项规模宏大、影响长远的系统工程,正基于此,各种开发方案的设计必须立足于这一区情.因此,设立中央政府投资基金,建立国土整治基地是非常必要,也是切实可行的.     

产蛋鸡饲粮中添加磷脂的效果试验

选用罗曼褐壳蛋鸡152只．随机分成4组，基础饲报中添加0．5％、10％和1．5％磷脂为试验组，试验期30d。试验结果表明：各组间平均蛋重天显著性差异（P＞0．05）；添加1．5％磷脂的试验Ⅲ组在产蛋数、产蛋率方面均极显著高于对照组和其他试验组（P＜0．01）：试验Ⅲ组的料蛋比显著低于其他组，但蛋破损率较高。     

Estimating Individual-Level Risk in Spatial Epidemiology Using Spatially Aggregated Information on the Population at Risk

We propose a novel alternative to case-control sampling for the estimation of individual-level risk in spatial epidemiology. Our approach uses weighted estimating equations to estimate regression parameters in the intensity function of an inhomogeneous spatial point process, when information on risk-factors is available at the individual level for cases, but only at a spatially aggregated level for the population at risk. We develop data-driven methods to select the weights used in the estimating equations and show through simulation that the choice of weights can have a major impact on efficiency of estimation. We develop a formal test to detect non-Poisson behavior in the underlying point process and assess the performance of the test using simulations of Poisson and Poisson cluster point processes. We apply our methods to data on the spatial distribution of childhood meningococcal disease cases in Merseyside, U.K. between 1981 and 2007.     

Modeling Imbalanced Economic Recovery Following a Natural Disaster Using Input‐Output Analysis

Input‐output analysis is frequently used in studies of large‐scale weather‐related (e.g., Hurricanes and flooding) disruption of a regional economy. The economy after a sudden catastrophe shows a multitude of imbalances with respect to demand and production and may take months or years to recover. However, there is no consensus about how the economy recovers. This article presents a theoretical route map for imbalanced economic recovery called dynamic inequalities. Subsequently, it is applied to a hypothetical postdisaster economic scenario of flooding in London around the year 2020 to assess the influence of future shocks to a regional economy and suggest adaptation measures. Economic projections are produced by a macro econometric model and used as baseline conditions. The results suggest that London's economy would recover over approximately 70 months by applying a proportional rationing scheme under the assumption of initial 50% labor loss (with full recovery in six months), 40% initial loss to service sectors, and 10–30% initial loss to other sectors. The results also suggest that imbalance will be the norm during the postdisaster period of economic recovery even though balance may occur temporarily. Model sensitivity analysis suggests that a proportional rationing scheme may be an effective strategy to apply during postdisaster economic reconstruction, and that policies in transportation recovery and in health care are essential for effective postdisaster economic recovery.
