The body armor of ankylosaurians is a unique morphological feature among dinosaurs. While ankylosaurian body armor has been studied for decades, paleohistological analyses have only started to uncover the details of its function. Yet there has been an overall bias toward sampling ankylosaurian remains from the Northern Hemisphere, with limited quantitative studies on the morphological and functional evolution of the osteoderms composing their body armor. Here, we describe new ankylosaurian materials recovered from the Late Cretaceous of Antarctica that, in combination with data compiled from the literature, reveal new insights into the evolution of the ankylosaurian body armor. Based on histological microstructure and phylogenetic results, the new Antarctic material can be assigned to Nodosauridae. This group shares the absence/poor development of their osteodermal basal cortex and highly ordered sets of orthogonal structural fibers in the superficial cortex. Our morphospace analyses indicate that large morphological diversity is observed among both nodosaurids and ankylosaurids, but osteoderms became more functionally specialized in late-diverging nodosaurids. Besides acting as effective protection against predation, osteoderms also exhibit highly ordered structural fibers in nodosaurids, enabling a decrease in cortical bone thickness (as in titanosaurs), which could have been co-opted for secondary functions, such as calcium remobilization for physiological balance. The latter may have played a key role in nodosaurid colonization of high-latitude environments, such as Antarctica and the Arctic Circle.

Introduction: The proportion of Canadians receiving anticoagulation medication is increasing. Falls in the elderly are the most common cause of minor head injury and an increasing proportion of these patients are prescribed anticoagulation. Emergency department (ED) guidelines advise performing a CT head scan for all anticoagulated head injured patients, but the risk of intracranial hemorrhage (ICH) after a minor head injury (patients who have a Glasgow comma score (GSC) of 15) is unclear. We conducted a systematic review and meta-analysis to determine the point incidence of ICH in anticoagulated ED patients presenting with a minor head injury. Methods: We systematically searched Pubmed, EMBASE, Cochrane database, DARE, google scholar and conference abstracts (May 2017). Experts were contacted. Meta-Analyses and Systematic Reviews of Observational Studies (MOOSE) guidelines were followed with two authors reviewing titles, four authors reviewing full text and four authors performing data extraction. We included all prospective studies recruiting consecutive anticoagulated ED patients presenting with a head injury. We obtained additional data from the authors of the included studies on the subset of GCS 15 patients. We performed a meta-analysis to estimate the point incidence of ICH among patients with a GCS score of 15 using a random effects model. Results: A total of five studies (and 4,080 GCS 15, anticoagulated patients) from the Netherlands, Italy, France, USA and UK were included in the analysis. One study contributed 2,871 patients. Direct oral anticoagulants were prescribed in only 60 (1.5%) patients. There was significant heterogeneity between studies with regards to mechanism of injury, CT scanning and follow up method (I2 =93%). The random effects pooled incidence of ICH was 8.9% (95% CI 5.0-13.8%). Conclusion: We found little data to reflect contemporary anticoagulant prescribing practice. Around 9% of warfarinized patients with a minor head injury develop ICH. Future studies should evaluate the safety of selective CT head scanning in this population.

Globalization is not simply a matter of transnational trade, and of the state, non-state and supra-state legal regimes which facilitate, regulate or resist it; it also involves transnational social, cultural, intellectual and ideological forces. These forces play upon strategically located knowledge-based elites which play an important role in restructuring the legal fields by which public and public and private institutions are constituted. Canada's experience of globalization—unique because of proximity to the United States—has been both exemplified and, in part, shaped by the fate of its knowledge-based elites, including the business community (especially that part of it involved directly or indirectly with transnational corporations), academics and intellectuals, lawyers, artists and other cultural figures, and individuals involved in politics and public administration. Because of the effects of this “globalization of the mind” upon the institutions which all of these elites inhabit, state and non-state legal fields associated with them have been transformed.

Barely three years ago, as chairman of the SSHRC's Consultative Group on Research and Education in Law, I released a report entitled Law and Learning. This report — in its diagnosis hardly more than a systematic compilation and empirical verification of “what we knew but could not tell” — contained a series of recommendations for the invigoration of Canadian legal scholarship. Several of these recommendations related to the need to diversify the types of legal research being conducted, to strengthen the research community by the development of networks and centres of activity, and to communicate the results of new research endeavours to relevant professional audiences, as well as to the public.

For me, therefore, the establishment of the Canadian Law and Society Association and the publication of the Canadian Journal of Law and Society are events of special significance. I am pleased — indeed flattered — to be involved in these new and important enterprises, albeit in a largely symbolic way. My pleasure is only enhanced by being afforded both a platform for pontification (the Editor has absolved me from the obligation to provide footnotes), and a collective script to which I can add what amounts to a postscript to our report.

Traps baited with the sex pheromone of the bertha army worm moth, Mamestra configurata (Walker), were operated at 36 sites across the prairie provinces in 1976 and 1977. They captured ca. 15 times as many bertha moths as did light traps and were considered to constitute a useful method for detection of adults of this species.
