正The world should utilize the opportunity to benefit from China’s experience Since 1978, the People’s Republic of China broadly embarked on an era—which came to be known as reform and opening up—where it observed and tried to learn from the world around it. Many different ideasfrom China’s experience 相似文献

Controversial 20th-century British politician Enoch Powell once noted that all political careers in Great Britain end in tears. With Theresa May, his words proved true not just figuratively but literally. As the British prime minister announced on May 24 that she would step down on June 7, observers could see her face consumed with emotion and tears well up in her eyes. It was a bathetic note to end a chaotic, and for many, in glorious, period. 相似文献

The internal election of a new British Conservative Party leader at the end of July also meant that the United Kingdom(UK)gota new primeminister.Boris Johnson comes to power therefore via a route with no national election to legitimize him. He is also, even in his own party, a divisive figure. 相似文献

This article discusses the U.S. Global Magnitsky Act, which was passed in 2016 and which provides a mechanism for the U.S. government to sanction foreign individuals and entities that are involved in human rights abuses and large scale corruption. It also discusses the opportunities that the Act provides for civil society organizations to influence the designation process and the additional due diligence measures that businesses should take in order to ensure compliance with the Act. 相似文献

Policy analysts, like allegorical homesteaders, face the seemingly unmanageable task of coping with the wilderness of ill-structured problems, while concurrently attending to well-structured problems, which can be addressed with conventional methods of policy analysis. What has appeared thus far as an unmanageable task may become manageable once analysts acknowledge the principle of methodological congruence: The appropriateness of a particular type of method is a function of its congruence with the type of problem under investigation.
To be sure, conventional methods of the first type are appropriate and useful for solving first-order problems, which are relatively well-structured. Contexts of practice, however, are pervaded by second-order problems which, variously described as squishy, messy, or ill-structured, are the class of all first-order problems. Just as methods of the first type are congruent with the simple analytic demands of first-order problems, so are methods of the second type congruent with the complex analytic demands of second-order problems. When policy analysts fail to observe this principle of methodological congruence they are likely to solve the wrong problem.
Methods of the second type are not limited to general heuristics, but include specific and readily comprehensible procedures for estimating the boundaries and structure of ill-structured problems. Since these estimation procedures appear to satisfy requirements of inductive estimates in general, policy analysts can assess their own performance in providing approximate answers to the right question, thus coping with the enemies who lurk in the wilderness of conventional policy analysis. 相似文献

In forensic DNA analysis, the samples recovered from the crime scene are often highly degraded leading to poor PCR amplification of the larger sized STR loci. To avoid this problem, we have developed STR markers with redesigned primer sequences called "Miniplexes" to produce smaller amplicons. To assess the effectiveness of these kits, we have tested these primer sets with enzymatically degraded DNA and compared the amplifications to a commercial kit. We also conducted sensitivity and peak balance studies of three Miniplex sets. Lastly, we report a case study on two human skeletal remain samples collected from different environmental conditions. In both types of degraded DNA, the Miniplex primer sets were capable of producing more complete profiles when compared to the larger sized amplicons from the commercial kit. Correct genotypes were obtained at template concentrations as low as 31 pg/25 microL. Overall, our data confirm that our redesigned primers can increase the probability of obtaining a usable profile in situations where standard kits fail. 相似文献
