Advances in Psychology (AP) , 2016, DOI: 10.12677/AP.2016.612160
Abstract:
目的:引进和修订Dickman冲动量表(Dickman’s Impulsivity Inventory, DII),在大学生中,检验DII中文版的信度、效度。方法:对500名在校大学生进行Dickman冲动量表测查,并间隔四周后进行重测。结果:DII总量表内部一致性系数为0.649,分量表的内部一致性系数均在0.7以上;重测信度为0.748;与Buss和Perry攻击问卷显著相关;验证性因素分析显示结构拟合良好。结论:DII是一个比较好的评估冲动行为的工具。
Objective: To introduce and revise Dickman impulse scale (Dickman’s Impulsivity Inventory, DII) and test its reliability and validity among college students. Methods: The DII was tested in 500 Chinese college students, and retested after four weeks. Results: The DII internal consistency coef-ficient is 0.649; subscales of internal consistency coefficients are above 0.7; retest reliability is 0.748; it has a significant correlation with the Buss and Perry attack questionnaire; confirmatory factor analysis showed that the structure fitting is good. Conclusion: The DII is a good tool for a better assessment of impulsive behavior.
卫宁灌区水权转让节水工程节水量计算方法探讨
Discussion on Water-Saving Quantity Calculation Method of Water Rights Transfer of Water-Saving Engineering in the Irrigation Area of Weining

Abstract:
宁夏当地水资源十分匮乏,经济社会发展主要依赖于过境黄河水。近年来通过水权转让,缓解了新上工业项目用水问题。水权转让主要是通过引黄灌区渠道衬砌,节约渠道渗漏水量来实现节水。为了准确核定水权转让工程节水量,针对水权转让节水改造工程中渠道衬砌节水量的计算方法,根据节水量的计算原理,通过灌区长期监测资料分析并提出参数的确定方法,为节水量的分析计算提供参考依据。
Local water resources of Ningxia are scarce, and the economic social development relies mainly on the Yellow River. In recent years through the water rights transfer, the water problem of new industrial projects is relieved. Water rights transfer refers to the Yellow River irrigation channel lining diversion, through saving water leakage so as to realize water-saving. In order to accurately check and ratify the water-saving quantity of water rights transfer engineering, aiming at channel lining water-saving quantity calculation method of water rights transfer of water-saving engineering, based on the water-saving quantity calculation principle, this paper analyzes the long-term monitoring data in the irrigation area and proposes the method to determine parameters, providing reference for the analysis and calculation of water-saving quantity.

中国气候变化形象形成的国际传播学分析

华东师范大学学报(哲学社会科学版) , 2013,
Abstract: 中国希望在气候变化问题上树立负责大国的形象,实际情形却相去甚远,中国被帖上各种负面标签,形成了“中国气候威胁”的国际形象。从国际传播学的角度看,“中国气候威胁”形象的形成在于多元国际传播主体的合力塑造、多样化传播渠道的共同传播,以及传播者符合国际受众情感和道德观的传播方式。中国关注这种现实,建立恰当的国家对外传播模式,争取中国气候外交话语权,对消解中国“气候威胁”话语,重塑中国在气候变化领域的道义形象有重要意义。
MIMD计算机上的一个稳定并行算法

计算数学 , 1989,
Abstract: 在MIMD计算机上解稠密线性方程组的问题,见[1]与[2].这两篇文章研究了基于高斯消去法和G-J消去法以及Givens变换法的实用并行算法,推得这三个并行算法的效率分别为2/3,4/7和4/9,且以并行高斯消去法为最佳.
从土地利用规划入手提高地质灾害的防治水平――兼议地质灾害风险区划的急迫性与重要性

地质通报 , 2009,
Abstract: 国际减灾战略已从场地尺度工程性“硬”措施转向区域土地规划限制等“软”措施,即通过土地利用规划手段来限制土地开发行为,这是防范地质灾害最有效的手段。从土地利用规划和土地审批的法律地位、地质灾害填图与区划的公益性基础工作和实施地质灾害风险带土地开发限制管理等方面介绍了国际经验,并提出中国开展土地利用规划预防地质灾害的具体建议。

基于多样性检测的双子群多目标粒子群算法
韩敏,
- , 2017, DOI: 10.13195/j.kzyjc.2016.1382
Abstract: 为了平衡多目标粒子群算法的多样性和收敛性,提出一种基于多样性检测的多子群多目标粒子群算法.首先,将多样性检测方法引入到多目标粒子群算法中,并结合多目标粒子群算法的特点进行改进.然后,将种群分为两个不同分工的子群,一个子群保持较好的多样性,在搜索空间进行全局搜索;另一个子群保持较好的收敛性,在Pareto前沿附近进行局部搜索.最后,根据多样性度量指标调整两个子群的搜索行为,以达到兼顾多样性和收敛性的目的.在标准测试问题上的仿真结果表明了所提算法的有效性.
