China scholars have examined the ‘China threat’ theory from various theoretical perspectives, offered a range of explanations for the theory's emergence and forecast the potential implications for US–China relations. However, few scholars have empirically studied the ‘China threat’ theory through the lens of the US media. This is a critical oversight, because the media plays a pivotal role in shaping US public opinion and US foreign policy, and the media is a key channel for ‘China threat’ dissemination and popularization. This study seeks to redress this oversight by empirically examining ‘China threat’ coverage in the US print media over a 15-year period from 1992 to 2006. We use content-analysis methodology to systematically collect, code and analyze ‘China threat’ data from five major US newspapers and to track the frequency and content of this coverage over time.

Our analysis reveals many interesting patterns in ‘China threat’ media coverage. First, the initial emergence of ‘China threat’ arguments in the US print media corresponded with the sharp upward turn in China's economic growth rates in the early 1990s. However, since the early 1990s, ‘China threat’ coverage has not mirrored China's steady growth. Rather, the media coverage was cyclic, featuring three key peaks (1996, 2000 and 2005) followed by subsequent declining interest. Second, our analysis reveals that the focus of these stories also varied over time. Perceptions of China as a political/ideological threat dominated media coverage in the earlier years (1992–1994) but steadily declined after 1995 and totally disappeared from the US print media after 2001. Perceptions of China as a military/strategic threat replaced political/ideological concerns in 1995, and the military focus has dominated media coverage ever since. Perceptions of China as an economic/trade threat persisted steadily throughout the 15-year time period with a clear uptick in recent years. We conclude this analysis by turning to the literature on realism, agenda setting and information processing to offer possible explanations for these empirical trends.  相似文献

The purpose of this response is to point out that claims of undue centrism in the MARPOR data are directly contradicted by its use to correct centrism in other leading policy measures including expert surveys.  相似文献

We compare unanimity rule and majority rule in their abilities to produce Pareto superior and Pareto optimal alternatives in fixed number of rounds of voting using a two-dimensional spatial voting model with random proposals, sincere proposals, and strategic proposals. Our findings show that for random or sincere proposals, majority rule is at least as likely to select a Pareto optimal outcome as unanimity rule. For strategic proposals, the subgame perfect equilibrium under unanimity rule is Pareto optimal. For other k-majority rules, the outcome is Pareto optimal or very close to it. For outcomes that are both Pareto optimal and Pareto superior, unanimity rule outperforms majority rule.  相似文献

The 2 common carotid arteries bifurcate in the neck into the internal and external carotid arteries. The internal carotid artery enters the skull and further divides into the anterior and middle cerebral artery. During its short course in the neck, the carotid artery travels encased in the carotid sheath along with the vagus nerve and the internal jugular vein. During its course in the neck, the carotid artery is quite superficial, making it vulnerable to both penetrating and blunt traumatic injuries. We report here a case of a 40-year-old man who presented to the emergency department after sudden collapse and loss of consciousness a day after an attempted strangulation. Imaging revealed large hemorrhagic infarcts in the left anterior cerebral artery and middle cerebral artery territories as well as a smaller infarcts in the right anterior cerebral artery territory necessitating emergency decompressive hemicraniectomy. Our case report adds to the existing literature on nervous system injury due to strangulation. Physicians should be aware of the possibility of delayed presentation of neurological deficit after attempted strangulation.  相似文献

This paper provides an overview of the development of the constitutional value of human dignity under German constitutional law. First, it provides a background to the German constitutional order then it places the constitutional value of dignity within the framework of the constitutional court’s jurisprudence on personality rights. It then progresses to an examination of specific cases that have developed personality rights and the importance of the constitutional court’s interpretation of personality and dignity in the personal and outer spheres within the framework of the German legal order. The article concludes with some observations and comparisons between German and American law in this area.  相似文献

Cyber weapons now are an extension of state power. In hopes of gaining a strategic advantage, many countries including the United States, Russia and China are developing offensive cyber capabilities to disrupt political, economic, and social institutions in competitor nations. These activities have led to a cyber arms race that is spiraling out of control. This imminent global threat challenges the international community to be proactive. The purpose of this article is to propose an international convention to throttle the development, proliferation and use of cyber weapons before they cause electronic Armageddon. We begin by examining three successful efforts in arms control and use the lessons learned to draft a convention that can serve as a starting point for formal multilateral negotiations.  相似文献

Bismuth oxychloride (BiOCl) was the first viable synthetic pearl pigment developed 50 years ago. It was only used for a limited time period in automotive paint (model years 1998–2000), serving to produce luster for a single Chrysler black metallic color. Identification of this pigment in an unknown automotive paint can thus facilitate determination of the vehicle of origin. Bismuth oxychloride imparts effects similar to those produced by silver/white mica pearlescent pigments, and such a pigment was used together with bismuth oxychloride in at least one original equipment manufacturer (OEM) basecoat. Silver/white micas are now used primarily in white pearl tricoat systems. This article describes the identification of bismuth oxychloride and silver/white mica pearlescent pigments in automotive finishes using FT‐IR spectroscopy, X‐ray fluorescence (XRF) spectrometry, and SEM/EDS analysis. Data for some cadmium pigments, which were used in automotive paint several decades ago, are also presented as they produce infrared absorptions similar to that of bismuth oxychloride.  相似文献

An algorithm incorporating multidetector computed tomography (MDCT), digital radiographs, and external examination was used to triage cases for noninvasive or complete autopsy after a natural disaster. The algorithm was applied to 27 individuals who died during or soon after the earthquake that struck the Republic of Haiti on January 12, 2010. Of the 27 cases reviewed, 7 (26%) required a complete autopsy to determine cause and manner of death. In the remaining 20 (74%), cause and manner of death were determined with a reasonable degree of medical certainty after review of circumstances, an external examination, and postmortem imaging by MDCT and digital radiography (noninvasive autopsy). MDCT was particularly useful in detecting skeletal fractures caused by blunt force injury which were not evident on digital radiographs. The algorithm incorporating postmortem MDCT can be useful in the triage of human remains for autopsy after a natural disaster.  相似文献

Research on procedural justice and legitimacy has expanded greatly across the social sciences in recent years. The process‐based model of regulation, which links people's assessments of procedural justice and legitimacy to their compliance with the law and legal authorities, has become particularly influential in criminology and sociolegal studies. A review of the previous research on perceived legitimacy highlights two important features. First, legitimacy has been conceptualized and measured in many different ways. Second, most of the research on legitimacy has focused on only a handful of developed nations. Using survey data from Trinidad and Tobago, this article examines the conceptualization and measurement of the perceived legitimacy of the law and legal authorities. The findings indicate that some of the prominent conceptual and measurement models used in previous research are not empirically valid in the Trinidadian context. The implications of the results for conceptualization, theory, and future research are discussed.  相似文献
