Political reforms and changes on the local level by the Putin–Medvedev leadership have resulted in an almost unprecedented turnover of leadership but they have aroused political conflict and even resistance by unsettling the political status quo throughout the 83 subnational units of the Russian Federation. The reforms have resulted in the marginalisation of the authority of city mayors, the recruitment from outside of chief executives of federation regions, and the polarisation of ethnic enclaves by national policies. Destabilising everything is the combination of a United Russia (Edinaya Rossiya) political party bent on national dominance, ambiguous liberal appeals and democratic reforms by President Medvedev, and a global economic recession. 相似文献

Grand strategy provides the strategic vision for a state in pursuit of its national interests. The current U.S. grand strategy straddles the line between isolationism and off-shore balancing. Based on the international relations theory of realism, these strategies view international actions as a zero-sum game. In other words, a country can only benefit at the expense of another. The zero-sum logic is clearly articulated in the “America First” strategic documents. It is also apparent in many of the president's speeches and policy actions. While the Trump administration's zero-sum approach has potential to rebalance burdens and level the playing field in such areas of trade, it is fraught with risks and jeopardizes the standing of the United States in the world. 相似文献

The Mozambique Eyecare Project was an international partnership to implement and research eye health education in Mozambique and the Africa region. An optometry degree was developed at Universidade Lúrio, Mozambique. In addition, existing eye health workers were upskilled with training. Researchers from various disciplines evaluated the project and its potential for impact on eye health in the region. The body of evidence generated from the research provides useful lessons for development programmes in general, as well as specific lessons for delivering eye health education and service delivery models for low-income settings. 相似文献

The quality of counterfeit items has increased dramatically, with modern global manufacturing being able to duplicate the materials, construction, and visual features of items. Detection of fraudulent coinage can parallel authentication of food, beverages, and manufactured goods by studying product-inherent features. Counterfeit detection is performed by comparing an Example group with a Questioned group. A model is developed for both groups using standard tests on individual pieces. Coin weight is used here as an illustration. The model should also follow the natural science of the system. In this case, the manufacturing process variation is known and steady, and the underlying distribution is known or can be determined from authentic pieces. The proposed detection method uses testing of many individual pieces, then using reverse-quality-engineering methods to identify possible sources. This strategy looks at the variation between individual pieces to determine the process capability of a machine, assembly line, or plant to create product consistency for a manufacturer. Fraudulent items may be manufactured within specification, but demonstrate a manufacturing process capability different than that of the authentic manufacturer. In this report, we examine the model previously reported and use reconstruction techniques to re-create the evidence set to validate the model, increase model accuracy, and confirm the conclusion previously reached, showing that the Questioned set is likely over 37% non-conforming by weight. In this case, the decision outcome of the analysis was improved by using additional methods not included in the modeling software package originally used. 相似文献

The U.S. military provides assistance to filmmakers in the form of use of military sites, equipment and personnel, which can provide significant cost savings to filmmakers. The military, however, routinely denies this assistance to filmmakers whose productions portray the military in a way it considers objectionable, actions that constitute viewpoint discrimination by the government. While this may seem to be an unconstitutional violation of First Amendment rights, application of forum law and the unconstitutional conditions doctrine lead to the conclusion that the military's viewpoint discrimination is permissible and does not violate the First Amendment. 相似文献

Previous research has found that reminding participants of their mortality creates a need for individuals to maintain and defend subjective cultural worldviews. As a result, mortality salient participants typically strive to uphold legal sanctions and also react negatively to individuals who espouse alternative worldview beliefs, exhibiting behaviors toward those targets ranging from verbal derogation to physical aggression. This paper extends this line of research by examining perceptions of hate crimes. Hate crimes represent a unique class of crime where both the perpetrator and victim may be viewed as worldview violators. Study 1 revealed that mortality salient participants were more supportive of hate crime legislation than were control participants when hate crimes were described in abstract terms and no specific victim was mentioned. In Study 2, a specific victim who posed a potential worldview threat was identified. In this case, mortality salient participants were less punitive toward offenders who attacked these specific worldview-threatening victims. 相似文献
