To analyze how Japan's competing objectives and specific policies have been evolving and how they trade off in today's regional security situation, this article argues that shifting Japanese foreign and security policies in Northeast Asia can be understood as ongoing responses to tensions along three key axes. First Japan confronts a tension between bilateralism and multilateralism; second Japan's economic and security interests are often at odds, and third, Japan still struggles with the competing pulls exerted by Asia on the one hand and the West (most particularly the United States) on the other.  相似文献

Despite widespread recognition that the use of counternarratives is an important strategic component of countering violent extremism, to date, there are no comprehensive guidelines on how to develop and distribute counternarratives to effectively reduce support for terrorism. To redress this, we offer communication and psychology theory-based procedures for (1) analyzing terrorist narratives, (2) constructing counternarratives that challenge terrorist narratives, and (3) disseminating the counternarratives to overcome barriers to persuasion. Analysts and practitioners can use such guidelines in developing counternarratives to reduce support for violent extremism.  相似文献

Postmortem computed tomography (PMCT) is integrated into the evaluation of decedents in several American medical examiner offices and medicolegal death investigative centers in many other countries. We retrospectively investigated the value of PMCT in a series of firearm homicide cases from a statewide centralized medical examiner’s office that occurred during 2016. Autopsies were performed or supervised by board-certified forensic pathologists who reviewed the PMCT scans prior to autopsy. PMCT scans were re-evaluated by a forensic radiologist blinded to the autopsy findings and scored by body region (head–neck, thoracoabdominal, and extremities). Injury discrepancies were scored using a modified Goldman classification and analyzed with McNemar’s test. We included 60 males and 20 females (median age 31 years, range 3–73). Based on PMCT, 56 (79.1%) cases had injuries relevant to the cause of death in a single body region (24 head–neck region, 32 thoracoabdominal region). Out of these 56 cases, 9 had a missed major diagnosis by PMCT outside that region, including 6 extremity injuries visible during standard external examination. Yet all had evident lethal firearm injury. We showed that PMCT identifies major firearm injuries in homicide victims and excludes injuries related to the cause of death in other regions when a single body region is injured. Although PMCT has a known limited sensitivity for soft tissue and vascular pathology, it can be combined with external examination to potentially reduce or focus dissections in some of these cases depending on the circumstances and medicolegal needs.  相似文献

Recent increases in deaths in the United States from synthetic opioids such as fentanyl and fentanyl analogues (fentanyls) have raised concerns about possible occupational exposures to these potent agents. Medicolegal death investigators and autopsy suite staff might perform job tasks involving exposure to fentanyls. The potential for exposure to fentanyls among medicolegal death investigators and autopsy technicians at a state medical examiner's office was evaluated through review of caseload characteristics, injury and illness logs, and procedures and policies and discussions with management and employee representatives. The evaluation showed that this medical examiner's office had low potential for work-related exposure to fentanyls; its standard operating procedures and personal protective equipment requirements should reduce the potential for occupational exposure. Medicolegal death investigation agencies can develop and implement guidance to control exposures and provide workforce education and training to reduce the potential for work-related exposure to fentanyls.  相似文献

This article contends that it is time for the armed forces to revisit their schools, day rooms, wardrooms, squadron meeting places, headquarters, bases and posts to increase the level of awareness and the teaching of professional norms.  相似文献

The article argues that Islamist terror is driven by irrational forces; it analyzes jihadist values and doctrines that animate Islamic revolutionaries; it then contends that jihadist movements go through a cycle of mobilization, extremism, implosion and recreation. Finally, it assesses the prospects for jihadist revitalization, extremism, and decline in Syria and the Sahel. Examples from the Iraqi and Algerian jihadist campaigns are used for illustrative purposes throughout.  相似文献

For at least a decade, there have been numerous Yemeni, Saudi, and other countries’ assertions that Iran has been involved in supporting northern Yemeni rebels seeking autonomy from the Sana’a government. Iranian diplomatic and political support for this rebellious group (known as the Houthis) is undeniable, but Iranian military assistance for them has not always been easy to prove. This situation appeared to change in 2011 when Iran's increased involvement in Yemen occurred in response to both the chaotic situation there during the final year of the Saleh regime and the danger that the Arab Spring revolutions would leave Iran increasingly isolated. Evidence of Iranian efforts to supply weapons to the Houthis now seems overwhelming in contrast to uncertain reports prior to 2011. In addition, at least some of Yemen's southern secessionists also appear to be receiving at least limited Iranian financial support.  相似文献
