The aim of the study was to detect whether the Willems model, developed on a Belgian reference sample, can be used for age estimations in United Arab Emirates (UAE) children. Furthermore, it was verified that if added third molars development information in children provided more accurate age predictions. On 1900 panoramic radiographs, the development of left mandibular permanent teeth (PT) and third molars (TM) was registered according the Demirjian and the Kohler technique, respectively. The PT data were used to verify the Willems model and to develop a UAE model and to verify it. Multiple regression models with PT, TM, and PT + TM scores as independent and age as dependent factor were developed. Comparing the verified Willems‐ and the UAE model revealed differences in mean error of ?0.01 year, mean absolute error of 0.01 year and root mean squared error of 0.90 year. Neglectable overall decrease in RMSE was detected combining PM and TM developmental information.  相似文献

This article presents an exploratory study of jihadi extremist groups’ videos using content analysis and a multimedia coding tool to explore the types of video, groups’ modus operandi, and production features that lend support to extremist groups. The videos convey messages powerful enough to mobilize members, sympathizers, and even new recruits to launch attacks that are captured (on video) and disseminated globally through the Internet. They communicate the effectiveness of the campaigns and have a much wider impact because the messages are media rich with nonverbal cues and have vivid images of events that can evoke not only a multitude of psychological and emotional responses but also violent reactions. The videos are important for jihadi extremist groups’ learning, training, and recruitment. In addition, the content collection and analysis of extremist groups’ videos can help policymakers, intelligence analysts, and researchers better understand the extremist groups’ terror campaigns and modus operandi, and help suggest counterintelligence strategies and tactics for troop training.  相似文献

Each year, the United States invests about $45 billion in research conducted by federal researchers within federal laboratories. These efforts generate extensive social benefits when results are transferred to the private sector. It is important that we effectively quantify the economic and societal impact of federal technology transfer activities to inform taxpayers and policymakers about the value of public investments in this form of research. The Argus II device, an artificial retina commercialized in the United States by Second Sight in 2013, provides a rich example of how private sector innovation can be enhanced by research collaborations with federal labs and academia. Over the 25-year journey from idea to product, Second Sight carried out research and development collaborations with six Department of Energy national laboratories and seven universities. The case of Argus II also offers valuable insight into (1) how private industry, academia, and government can work together to bring socially beneficial innovations to fruition and (2) the tradeoffs inherent in these public–private collaborations. In this paper, we use a Markov model to estimate the realized and potential future social benefits associated with Argus II. We provide an interactive tool that can be used to replicate our findings and modify assumptions using updated patient information as it becomes available. We also provide insight into the aspects of federal involvement surrounding the development of Argus II that contributed to its successful commercialization and discuss other spillover benefits from these public–private collaborations.  相似文献

The Tunisian political crisis that started in July 2013 was resolved thanks to the National Dialogue hosted by the Quartet who were recently awarded the Nobel Peace Prize. The ND was a collusive transaction that allowed Ennahdha to escape accountability for its political responsibility. Nevertheless, by resolving the crisis, it generated legitimacy. It also contributed significantly to the current configuration of alliances within the power circle by making possible the alliance between Ennahdha and Nidaa Tounes after the 2014 elections. The mechanisms of mutual recognition between Ennahda and Nidaa Tounes help ensure political stability by reinforcing the government’s position. However, this alliance appears to be a source of delegitimation now that the government is facing many challenges (economic crisis, security crisis and disputed political decisions). The critical situation, particularly at the security level, challenges the idea of compromise and undermines the government’s ability to make the people believe in its legitimacy.  相似文献

A survey was conducted to assess the content coverage of more than 100 divorce education programs for parents in North America. Fifty-six percent of the programs were mandatory for at least some categories of divorcing parents. Results showed that the most intensively covered topics involved the effects of divorce on children and the benefits of parental cooperation. Moderate coverage was devoted to skills acquisition, such as conflict management and parenting, and to the effects of divorce on parents. Minimal coverage was devoted to "nuts and bolts" and legal issues. The results are discussed in terms of issues likely to emerge as a result of this content coverage.  相似文献
