In the criminal cases of driving under the influence (DUI), DNA evidence can be collectedfrom the deployed airbag of the motor vehicle and submitted to the crime lab for touch DNA analysis.The evidence can be acquired when the skin cells are observed on the surface of the airbag in a trafficaccident. However, the low quantity or quality of the evidence collected from a crime scene preventsfurther identification analysis in many cases. In the current study, we reported a case of identifyingtouch DNA extraction from the shed skin cells from the deployed airbag of a motor vehicle. We man-aged to collect DNA evidence from the shed skin cells in an airbag using a proper approach of collec-tion and extraction. The 5.87 ng of extracted DNA was sufficient for genotyping and forensic identifica-tion, which helped to identify the driver of the car in collision with a pier in the street. In DUI casesand other traffic accidents, therefore, the amount of touch DNA extracted from the deployed airbag canbe sufficient for DNA marker genotyping and further analysis. 相似文献
Among the central tenets of social identity theory are the arguments that individuals’ attitudes and behavior are shaped by (1) perceptions of threat by out-groups toward individuals’ in-group(s) and (2) the strength of individuals’ identification with the in-group perceived to be under threat. In this paper we explore how American identity and Americans’ perceptions of immigrant threat work together to shape their vote choices in the 2016 presidential election. With the presidential campaign of Donald Trump characterized by strong rhetoric that emphasized immigrant threat and American identity themes, we suggest that the effects of immigrant threat perceptions are amplified by individuals’ American identity, with those who have a strong American identity more likely to translate immigrant threat perceptions into support for Trump than those with weaker levels of American identity. Moreover, we consider whether the effects of American identity on vote choice are activated and moderated by individuals’ perceptions of immigrant threat. Using data from the 2016 American National Election Study, we find that the effects of immigrant threat perceptions and American identity on vote choice are magnified by each other: the effects of immigrant threat perceptions are enhanced among individuals with a strong American identity, and the effects of American identity are activated and magnified by perceptions of immigrant threat.
Battlefield for Strategic Rivalry In recent years, the Asia-Pacific strategic configuration has entered a stare of in-depth readiustments. The relative decline of the United States,China's rapid rise, Russia's fast revival and Japan's quickening step toward a "normal country" have combined to turn regional multi-polarity into a reality. Not surprisingly, the world' s strategic structure has begun to focus on the region, with intensifying rivalry among major countries centered on economic competition and aggravating geopolitical game conducive to a security dilemma. As a matter of fact, U.S.-Japanese provocations have been at work in tuming regional hotspot issues into tools for such a game. As a result, escalating security threats to China in the East and South China Seas are converging into potential risks of collision and conflicts with other contenders. 相似文献
