The remains of an unidentified female neonate were discovered in a field in central Missouri. Examination revealed bilateral absence of the parietal bones. A search of the literature describing similar defects suggests that the present case represents a unique condition, described here for the first time.  相似文献

Technologies play crucial roles in security politics. In a recent push to understand the dynamic interplay between technologies and politics, IR scholars increasingly draw on reflexive research traditions. The aim is to understand the social and political practices that influence the shape, design and use of security technologies instead of assuming that technologies have linear, independent effects on politics. This SPSR debate draws on this new perspective and applies it to topics salient in Swiss public debate. Its contributions analyze how cybersecurity, predictive policing, drones, artificial intelligence, targeted sanctions, urban design and spyware are deliberated, negotiated, programmed and critiqued in Switzerland. They chart different analytical avenues with which to address the recursive and non‐linear relationship between security politics and technologies, and, by familiarizing readers with the tenets and diversity of reflexive political science research, seek to give that longstanding scholarly research tradition better visibility in the Swiss political science community.  相似文献

Undergraduate public law courses often attract students with competing expectations. Some students enroll in these courses to prepare for law school, while others enroll in the courses to gain a broader understanding of courts in the American system of government. These differing student constituencies can create a dilemma for instructors. A course designed to cater to students with a general interest in the judiciary may not afford prelaw students with an appreciation for the demands of the legal profession. Conversely, a course narrowly tailored toward prelaw students risks alienating the majority of students for whom this class may be their only look at the judiciary. As a means to promote pedagogical balance and to appeal to varied student constituencies, we profile five public law simulations in this article that engage students in active learning and promote a greater understanding of law and courts.  相似文献

ABSTRACT

This report examines accuracy and bias in national- and state-level preelection polls conducted during the 2016 U.S. general election cycle. Overall, national polls in 2016 were somewhat more accurate than in 2012, but statewide polls were less accurate. Patterns across the board suggest polls underestimated Republican support in the presidential, U.S. Senate and gubernatorial races. Nevertheless, these biases were generally statistically insignificant, suggesting significant bias in preelection polls was scarce in 2016.  相似文献

This article focuses on the degree to which friends’ influence on substance use is conditioned by the consistency between their behavior and that of schoolmates (individuals enrolled in the same school, but not identified as friends), contributing to the literature on the complexity of interactive social influences during adolescence. Specifically, it hypothesizes that friends’ influence will diminish as their norms become less similar to that of schoolmates. The authors also propose that this conditioning relationship is related to the density of the friendship group. This study uses data from the National Longitudinal Survey of Adolescent Health (AddHealth) (n ~ 8,000, 55 % female) to examine the interactive relationship between friend and schoolmate influences on adolescent substance use (smoking and drinking). The sample contains students ranging from age 11 to 22 and is 60 % White. The findings demonstrate that, as the substance use of the friendship group becomes more dissimilar from schoolmates’ substance use, the friendship group’s influence on adolescent substance use diminishes. Further, the results demonstrate that this conditioning relationship does not emerge when the friendship group is highly dense.  相似文献
