东莞模式:中国经济走向世界的成功尝试 总被引:3,自引:0,他引:3
王蕾 《中共宁波市委党校学报》2002,24(2):42-44,55
东莞模式是对东莞经济发展道路的一种概括,主要指东莞充分发挥人缘、地缘、政策优势,以加工贸易为突破口,以外向型经济为主导,迅速实现农村工业化、产业现代化、经济国际化的经济发展模式.这是一种三赢模式,它不公使东莞赢得了在国际经济中的一席之地,而且使国际资本寻找到了一个低风险、高回报、较稳定的投资场所,同时,更为重要的,这是中国经济走向世界的成功尝试.东莞模式为我国加入WTO中国经济大规模地融入国际经济提供了许多有益的经验. 相似文献

Correlation between plasma and bone marrow tricyclic antidepressants has not been studied before. Two groups of rabbits were given 10 and 20 mg of desipramine/kg body weight, respectively. Desipramine was administered to the animals once daily by mouth for 5 days. On the fifth day the animals were sacrificed and blood and bone marrow samples were collected and analyzed using a high performance liquid chromatographic (HPLC) method. Data showed that a correlation exists between bone marrow and blood desipramine. The bone marrow desipramine concentration increased as its blood levels increased. The average ratio of bone marrow to blood desipramine +/- S.D. (standard deviation) in both dosage groups was 37.2 +/- 4.46 with a range of 30.99-44.82. This investigation is promising and shows that bone marrow could be used as an alternative tissue in the absence of a suitable blood sample. 相似文献

The Green River Murder Investigation in King County, Washington, is currently the longest active serial murder investigation in U.S. history. During its course, over 26 separate scenes with from one to five victims each have been processed. The experience of the authors is presented in order to acquaint other agencies with techniques of outdoor scene processing that have evolved during recovery of remains from Green River and other skeletal cases. 相似文献

Identification of the driver in two-rider motorcycle accidents. Inguinal contusion-laceration as an indication of the driver 总被引:1,自引:0,他引:1
H Shiono A Akane K Matsubara K Tanabe S Takahashi 《The American journal of forensic medicine and pathology》1990,11(3):190-192
In motorcycle accidents involving two riders, medicolegal identification of the driver is necessary when one or both riders die. It is particularly important in the latter case, because the survivor almost always insists that he or she was not driving. One characteristic injury that distinguishes the driver from the passenger is inguinal contusion-laceration (accompanied internally by pelvic fracture). This injury, caused by collision of the pelvis with the fuel tank, identifies the driver. 相似文献

<正> 向市场经济转型的目标正式确立,似乎再一次给了法学为自己定位和重新发现自身价值的机会。随“市场经济是法制经济”这一命题的提出,法学界显得相当活跃和颇有生机。从围绕这个命题而发表的许多文章来看,法学家们主要做的是两个方面的工作:一方面是为法学引入了许多以前可能被排斥或被忽视的新观念、新价值;另一方面,则再次强调了加强立法、严格执法的法治原则。值得注意的是,就后一个方面而言,我们目前的一般理论水平与十多年前经过“要人治还是要法治”的讨论所达到的认识相比,似乎并无很大的进展。法学研究现在面临的重 相似文献

Kindergarten policy varies widely both across and within states. Over the past decade, a number of states have instituted a full‐day kindergarten requirement and others are considering it as a way to increase educational achievement. Many parents also support full‐day kindergarten as a source of child care. This paper uses the Early Child Longitudinal Study–Kindergarten Class of 1998–1999 to evaluate the efficacy of this policy. In ordinary least squares, probit, county fixed effects, and instrumental variables models, we find that there are initial benefits for students and the mothers of students who attend full‐day kindergarten, but that these differences largely evaporate by third grade. Contrary to claims by some advocates, attending full‐day kindergarten is found to have no additional benefit for students in families with income below the poverty threshold. © 2006 by the Association for Public Policy Analysis and Management 相似文献
