舰艇编队对空防御火力分配评价模型

未来高技术条件下水面舰艇编队防空作战能力是其生存能力的关键因素.对舰艇编队防空来讲,进行硬抗击的武器主要是舰空导弹和舰炮两种,如何合理地利用这些武器,最大地发挥舰艇编队的防空作战能力,成为舰艇对空防御作战研究的一个重要课题.结合舰艇编队对空防御的实际情况,利用模糊数学的方法,建立了舰艇编队对空防御火力分配方案的模糊综合评价模型.

Nonparametric bayesian lifetime data analysis using dirichlet process lognormal mixture model

We propose a nonparametric Bayesian lifetime data analysis method using the Dirichlet process mixture model with a lognormal kernel. A simulation‐based algorithm that implements the Gibbs sampling is developed to fit the Dirichlet process lognormal mixture (DPLNM) model using rightly censored failure time data. Five examples are used to illustrate the proposed method, and the DPLNM model is compared to the Dirichlet process Weibull mixture (DPWM) model. Results indicate that the DPLNM model is capable of estimating different lifetime distributions. The DPLNM model outperforms the DPWM model in all the examples, and the DPLNM model shows promising potential to be applied to analyze failure time data when an appropriate parametric model for the data cannot be specified. © 2013 Wiley Periodicals, Inc.

Military Spending,Conflict and External Debt in Sub-Saharan Africa

The damaging economic effects of the debt crises on Africa in the late 1980s encouraged considerable research on the determinants of external debt in developing economies. Although sub-Saharan Africa's (SSA) debt was cut by two-thirds by 2008, through two debt relief programmes, debt in the region has since been rising at an increasingly rapid pace. This study provides an empirical analysis of the determinants of external debt in SSA over the period 1960–2016, using dynamic panel methods. It also considers two potentially important factors that have received relatively little attention. One is military spending, rarely considered, despite a number of well-publicised scandals over the procurement of unnecessary and expensive high-tech weapons systems. A second, is the possibility that the countries studied have been involved in conflict. The empirical results point to a positive impact of military spending on external debt, but with some evidence of heterogeneity across the countries. Furthermore, findings indicate that the positive effect of military expenditure on debt becomes more marked in countries that have been affected by conflict. These results imply that policies to improve security and reduce military spending could be beneficial in reducing external debt and, potentially, improving economic performance in the region.     

谈部队基层干部队伍建设

部队建设的关键在基层,基层建设的关键在中队干部,他们素质的高低直接影响到基层建设的好坏。根据当前消防中队干部队伍的现状,加强基层干部队伍建设的着力点应在于：夯实中队干部思想基础,提高中队干部履职能力,完善中队干部管理措施。
