Looking at U.S. Int‘l Status in the Perspective of Its Inner Institution

America's international status is the key factor that determines the overall international structure. This is an old as well as a new topic in the academia of international relations. The Iraq war in 2003 reveals America's strong points and weak points as well. On the one hand, U. S. military strength is unmatched in the world; on the other hand, America is incapable of doing anything in dealing with many problems. This paradox caused scholars to ponder over the issues such as how strong Am…     

也门日益严重的水资源短缺问题

也门是世界水资源严重缺乏的国家之一,目前,全国每年可再生的水资源总量不超过25亿立方米,其中,15亿立方米存在于地表,另外10亿立方米为地下水。水资源的消耗量至1995年即已达到32亿立方米。而此前世界银行发布的一份报告称,也门年均水资源总量约为21亿立方米,年均消耗量约为28亿立方米,人均水占有量仅为150~160多立方米,远远低于中东和东非国家1250立方米的年人均水占有量。在萨那盆地,尽管其每年开采的水源总量已达到人均224立方米,但仍有约10%的人口年均水占有量仅为42立方米。造成这一局面的主要原因在于也门缺少河流、遍布全国的具有防…     

Randomized experiments in criminology: What have we learned in the last two decades?

This paper aims to review randomized experiments in criminology with offending outcomes and reasonably large numbers that were published between 1982 and 2004. A total of 83 experiments are summarized, compared with only 35 published between 1957 and 1981: 12 on policing, 13 on prevention, 14 on corrections, 22 on courts, and 22 on community interventions. Randomized experiments are still relatively uncommon, but there have been more large-scale multi-site experiments and replication programs. There have also been several experiments in which 100 or more places were randomly assigned. Relatively few experiments (only 10 out of 83) were conducted outside the United States. Meta-analyses suggest that prevention methods, correctional therapy, batterer programs, drug courts, juvenile restitution and deterrent policing were effective in reducing offending, while Scared Straight and boot camp programs caused a significant increase in offending.     

"在最坏的可能性上建立我们的政策"--毛泽东为什么在七大会议上讲17条困难

在党的历史上,使用"团结"和"胜利"来定位全国代表大会,是从1945年的七大开始的.召开这次大会的时候,党的历史问题解决了;艰难困苦的抗日战争,胜利指日可待;战后党的路线方针也有了明确的共识.因此,称这次大会为"团结的大会,胜利的大会"一点也不为过.     

漫议"随、陆无武,绛、灌无文"--从毛泽东让许世友读《红楼梦》说起

1973年底,有过一次八大军区司令员对调的事情.调动前,12月21日,毛泽东召集军队一些高级将领谈话,讲起了<红楼梦>.从记录稿看,他是对着许世友说的:"你现在也看<红楼梦>了吗?要看五遍才有发言权呢."随后,话锋一转:"你就只讲打仗,你这个人以后搞点文学吧.‘常恨随、陆无武,绛、灌无文'.绛是指周勃,周勃厚重少文,你这个人也是‘少文'."     

《道路交通控制》实践教学研究

教学是一个特殊的认识过程,在这个过程中,实践活动不仅能使学生获得大量的直接经验,促进理论知识的消化,而且是达到认知、情感、技能等教学目标的必不可少的有效途径。针对《道路交通控制》课程具有较强可操作性的特点,应在课程教学中进行实战实践教学,从三方面入手:1.孤立交叉口控制实战教学;2.干线控制的实战教学;3.区域控制的实战教学。
