The COVID-19 crisis demanded rapid, widespread policy action. In response, nations turned to different forms of social distancing policies to reduce the spread of the virus. These policies were implemented globally, proving as contagious as the virus they are meant to prevent. Yet, variation in their implementation invites questions as to how and why countries adopt social distancing policies, and whether the causal mechanisms driving these policy adoptions are based on internal resources and problem conditions or other external factors such as conditions in other countries. We leverage daily changes in international social distancing policies to understand the impacts of problem characteristics, institutional and economic context, and peer effects on social distancing policy adoption. Using fixed-effects models on an international panel of daily data from 2020, we find that peer effects, particularly mimicry of geographic neighbors, political peers, and language agnates drive policy diffusion and shape countries' policy choices. 相似文献

Between public debates about ‘hacking’ elections, so-called ‘fake news’ and online disinformation campaigns, it has become hard to imagine what free and fair elections in a digital environment could look like. This challenge is particularly pronounced for election observers who monitor free and fair elections. How should election observers fulfil this task when reliable data in online media campaigns are often not even available to media regulators? The following article provides a brief overview of existing challenges around online content regulation and how these apply to elections and election observation. It then considers where resources for digital electoral observation exist and how most effectively to build on these before, in conclusion, discussing next steps and potential opportunities to develop digital election observation further. 相似文献

There is tension between three of the U.S. counterinsurgency doctrine's central goals: the restoration of security, democratization, and cultural respect. These goals are particularly difficult to reconcile when it comes to the treatment of women and children in contested areas. Those groups have unique security concerns that are margin-alized in the U.S. military's conceptions of security and they may be victims of violence that is tacitly permitted by efforts to show cultural respect. After discussing these problems as they appear in U.S. counterinsurgency doctrine the author shows how they shape events in real operations with the help of interviews conducted with veterans of the wars in Afghanistan and Iraq. 相似文献

Several decomposed body parts were received for examination by the Forensic Anthropology section of the Medico-legal Institute of João Pessoa, Paraíba, Brazil. The portions of the lower and upper limbs, ribs, vertebrae, and a skull were thoroughly examined. The biological profile indicated a male individual with an estimated age range between 23 and 57 years and a mean age of 35.2 years (SD = 9.4; phase IV, Suchey-Brooks). The skeleton showed injuries caused by sharp force and sharp-blunt force trauma that affected all body segments. Macroscopically, the lesions are mainly in the diaphyseal segments of the long bones, sacrum, pelvis, mandible, maxilla, scapulae, sternum, vertebrae, the distal epiphysis of the left fibula, and the distal epiphysis of the left tibia displayed characteristics compatible with injuries produced perimortem. It was not possible to determine the cause of death. DNA analysis resulted in a positive identification. Because of common difficulties faced in forensic practice, it is often not possible for forensic anthropologists to go to the crime scene, X-ray or body scanners are frequently unavailable, and the victim’s medical and/or dental records are sometimes absent. These difficulties make identification ultimately depend on genetic analysis, which is more time-consuming than other identification methods. Despite this, bone fragment examination in dismemberment cases is a complex task. Forensic Anthropology can shed light on cases involving the identification of dismembered remains, which are challenging because of the number of traumatic injuries, as well as different injury patterns, on bones. 相似文献

ABSTRACTIn political regimes where traditional mass media are under state control, social networking sites may be the only place where citizens are exposed to and exchange dissident information. Despite all the attempts, complete control of social media seems to be implausible. We argue that the critical information that people see, read and share online undermines their trust in political institutions. This diminishing trust may threaten the legitimacy of the ruling regime and stimulate protest behaviour. We rely on original survey data of Kazakhstani college students to confirm these expectations. The data are unique in that they directly measure exposure to critical/dissident information, as opposed to simply assuming it. The analysis leverages Coarsened Exact Matching to simulate experimental conditions. This allows us to better identify the consequential mechanism and the attitudinal precursor by which social media influence protest in an authoritarian context. 相似文献
