Abstract. While creation of the United States Geological Survey's topographic maps of the eastern Alaska Arctic were an outstanding accomplishment for their time, they nonetheless contained significant errors when made in the late 1950s. One notable discrepancy relates to the tallest peak in the US Arctic: USGS maps of different scale alternate between Mt Chamberlin and Mt Isto. Given that many of the peaks here are close in height and covered with glaciers, recent climate change may also have changed their height and their order. We resolved these questions using fodar, a new airborne photogrammetric technique that utilizes Structure-from-Motion (SfM) software and requires no ground control, and validated it using GPS measurements on the peaks and using airborne lidar. Here we show that Mt Chamberlin is currently the 3rd tallest peak and that the order and elevations of the five tallest mountains in the US Arctic are Mt Isto (2735.6 m), Mt. Hubley (2717.6 m), Mt. Chamberlin (2712.3 m), Mt. Michelson (2698.1 m), and an unnamed peak (2694.9 m); these orthometric heights relative to the NAVD88 vertical datum, established with use of GEOID12B. We find that it is indeed plausible that this ranking has changed over time and may continue to change as summit glaciers continue to shrink, though Mt Isto will remain the highest under current climate trends. Mt Isto is also over 100 m higher than the highest peak in the Canadian Arctic, making it the highest peak in the North American Arctic. Fodar elevations compared to within a few centimeters of our ground-based GPS measurements of the peaks made a few days later and our complete validation assessment indicates a measurement uncertainty of better than ±20 cm (95 % RMSE). By analyzing time-series of fodar maps, we were able to detect topographic change on the centimeter-level on these steep slopes, indicating that fodar can be used to measure mountain snow packs for water resource availability or avalanche danger, to measure glacier volume change and slope subsidence, and many other applications of benefit to society. Compared to lidar, the current state-of-the-art in airborne topographic mapping, we found this SfM technique as accurate, more scientifically useful, and significantly less expensive, suggesting that fodar is a disruptive innovation that will enjoy widespread usage in the future.

Abstract. Though an outstanding achievement for their time, the United States Geological Survey (USGS) topographic maps of the eastern Alaskan Arctic nonetheless contain significant errors, and in this paper we address one of them. Specifically, USGS maps of different scale made in the late 1950s alternate between Mt. Chamberlin and Mt. Isto as the tallest peak in the US Arctic. Given that many of the peaks here are close in height and covered with glaciers, recent climate change may also have changed their height and their order. We resolved these questions using fodar, a new airborne photogrammetric technique that utilizes structure-from-motion (SfM) software and requires no ground control, and validated it using GPS measurements on the peaks as well as airborne lidar. Here we show that Mt. Chamberlin is currently the third tallest peak and that the order and elevations of the five tallest mountains in the US Arctic are Mt. Isto (2735.6 m), Mt. Hubley (2717.6 m), Mt. Chamberlin (2712.3 m), Mt. Michelson (2698.1 m), and an unnamed peak (2694.9 m); these heights are relative to the NAVD88 GEOID12A vertical datum. We find that it is indeed plausible that this ranking has changed over time and may continue to change as summit glaciers continue to shrink, though Mt. Isto will remain the highest under current climate trends. Mt. Isto is also over 100 m taller than the highest peak in Arctic Canada, making it the highest peak in the North American Arctic. Fodar elevations compared to within a few centimeters of our ground-based GPS measurements of the peaks made a few days later and our complete validation assessment indicates a measurement uncertainty of better than ±20 cm (95 % RMSE). By analyzing time series of fodar maps, we were able to detect topographic change on the centimeter level on these steep slopes, indicating that fodar can be used to measure mountain snow packs for water resource availability or avalanche danger, glacier volume change, and slope subsidence, as well as many other applications of benefit to society.

Over the past 30 years, NATO-Russia relations have come a long way. The present paper provides a retrospective analysis of the NATO-Russia relations that may shed new light on their current state and prospects for development. The author shows that after the collapse of the bipolar world, and the Russian Federation’s emergence on the international scene as a sovereign state, Moscow did not exclude the possibility of establishing partnership and even allied relations with the North Atlantic Alliance. In fact, during the 1990s2000s, Russia and the Alliance cooperated successfully in such areas as the fight against piracy and international terrorism, rescue at sea, etc. However, hopes for a full-fledged partnership between Moscow and Brussels did not materialize as a result of the Alliance’s advance to the East, to the Russian border. NATO’s eastward enlargement — combined with the firm position of the official Washington and Brussels on the unacceptability of Russia’s membership in the Alliance — meant a complete exclusion of Russia from the decision-making process on the European security. At the same time, for a variety of reasons, in the post-bipolar world the military-political dependence of the Western European subregion on Washington did not decrease, as many hoped, but, on the contrary, has increased, thus excluding for Moscow the very possibility to play on the contradictions between the United States and its European allies. Accession to the Alliance of the Eastern and Southern European ‘recruits’ (many of which shared strong anti-Russian sentiments) further limited the Russia’s possibilities for such maneuvering. The Alliance thus became an instrument of the US global domination — a domination which Moscow rejects categorically. The author concludes that in these circumstances, it will not be easy to overcome the military-political contradictions between Russia and NATO.

The Impact

This article examines the ebb and flow of the Quebec government’s economic and commercial relations with the United States in the period 1994–2017. The topic demonstrates the impact of three major forces on Quebec’s economic and commercial ties with the US: (1) the North American Free Trade Agreement (NAFTA) which became operational in 1994 and was fully implemented over a 15-year period; (2) the onerous security policies put in place by the US government in the decade following the horrific events of 11 September 2001; and (3) changing economic circumstances in the United States ranging from robust growth to the worst recession since the Great Depression of the 1930s. The article also indicates that the Quebec government continues to sponsor a wide range of activities in the United States, often more elaborate and extensive than comparable activities pursued by many nation-states with representation in the US. 1 1 Stéphane Paquin, ‘Quebec-U.S. Relations: The Big Picture’, American Review of Canadian Studies 46, no. 2 (2016): 149–61.

The research is devoted to the study of the origin of the historiography of the topic of the genesis of the US foreign policy. The key thesis of the work challenges the established position in the scientific literature about the fundamental role of the work of T. Lyman, Jr. «The diplomacy of the United States: being an account of the foreign relations of the country, from the first treaty with France, in 1778, to the Treaty of Ghent in 1814, with Great Britain», published in 1826. The article puts forward an alternative hypothesis: the emergence of the historiography of the genesis of the foreign policy of the United States occurred before the beginning of the second quarter of the XIX century – during the colonial period and the first fifty years of the North American state. A study of the works of thirty-five authors who worked during the 1610s and 1820s showed that amater historians expressed a common opinion about North America’s belonging to the Eurocentric system of international relations; they were sure that both the colonists and the founding fathers perceived international processes on the basis of raison d’être. The conceptualization of the intellectual heritage of non-professional historians allowed us to distinguish three interpretations of the origin of the United States foreign policy: «Autochthonous» – focused on purely North American reasons; «Atlantic» – postulated the borrowing of European practice of international relations by means of the system of relations that developed in the Atlantic in the XVII–XVIII centuries; «Imperial» – stated the adaptation of the British experience. The obtained data refute the provisions of scientific thought of the XX–XXI centuries and create new guidelines for further study of the topic.

New Nation

The ‘New World’ on the North American continent was founded in the 1600s on colonists’ willingness to take substantial risks. The notion of relieving at least some of the burdens of inevitable failure, in order to encourage productive risk-taking, has been part of the fabric of US law almost from the very beginning. After discovering that jailing debtors did very little to encourage fulfilment of debts, and it in fact depressed the economic productivity on which the colonies’ survival depended, several of the colonies experimented with limited insolvency and bankruptcy laws in the mid-1700s. After the Revolution, the issue of providing uniform and nationwide bankruptcy relief was enshrined in the US Constitution as part of the very foundation of the new nation. While the new US Congress was granted only limited rights to regulate general economic matters (the most significant such rights being reserved to the state and local legislative bodies), Article I, section 8, clause 4 of the US Constitution explicitly vested the federal Congress with the power to regulate bankruptcy.

ObjectiveTo generate a national multiple sclerosis (MS) prevalence estimate for the United States by applying a validated algorithm to multiple administrative health claims (AHC) datasets.MethodsA validated algorithm was applied to private, military, and public AHC datasets to identify adult cases of MS between 2008 and 2010. In each dataset, we determined the 3-year cumulative prevalence overall and stratified by age, sex, and census region. We applied insurance-specific and stratum-specific estimates to the 2010 US Census data and pooled the findings to calculate the 2010 prevalence of MS in the United States cumulated over 3 years. We also estimated the 2010 prevalence cumulated over 10 years using 2 models and extrapolated our estimate to 2017.ResultsThe estimated 2010 prevalence of MS in the US adult population cumulated over 10 years was 309.2 per 100,000 (95% confidence interval [CI] 308.1–310.1), representing 727,344 cases. During the same time period, the MS prevalence was 450.1 per 100,000 (95% CI 448.1–451.6) for women and 159.7 (95% CI 158.7–160.6) for men (female:male ratio 2.8). The estimated 2010 prevalence of MS was highest in the 55- to 64-year age group. A US north-south decreasing prevalence gradient was identified. The estimated MS prevalence is also presented for 2017.ConclusionThe estimated US national MS prevalence for 2010 is the highest reported to date and provides evidence that the north-south gradient persists. Our rigorous algorithm-based approach to estimating prevalence is efficient and has the potential to be used for other chronic neurologic conditions.

AbstractBackground:The US Census Bureau’s County Business Patterns (CBP) series provides a unique opportunity to describe the healthcare sector using a single, national data source.Methods:We analyzed CBP data on business establishments in the healthcare industry for 2000–2016 for all 50 states and the District of Columbia. Setting and facility types were defined using the North American Industry Classification System.Results:In 2016, CBP enumerated 707,634 US healthcare establishments (a 34% increase from 2000); 86.5% were outpatient facilities and services followed by long-term care facilities (12.5%) and acute-care facilities (1.0%). Between 2000 and 2016, traditional facilities such as general medical surgical and surgical hospitals (−0.4%) and skilled nursing facilities (+0.1%) decreased or remained flat, while other long-term care and outpatient providers grew rapidly.Conclusion:This analysis highlights the steady growth and increased specialization of the US healthcare sector, particularly in long-term care and outpatient settings.

Rethinking United States–Caribbean relations: towards a new mode of trans-territorial governance

Different Order

United States–Caribbean relations over the period of the last thirty or forty years have rarely—if ever—been analysed in a thoroughly satisfying way. It is a strange omission in the international relations literature given the proximity of the United States to the Caribbean, and vice versa. But the fact is that most accounts of the relationship have fallen prey to a powerful, but ultimately misleading, mythology by which small, poor, weak, dependent entities in the Caribbean have either created trouble for, or alternatively been confronted by, the ‘colossus to the north’ that is the United States in whose ‘backyard’ they unfortunately have to reside. Virtually all analysts of the US–Caribbean relationship have thus drawn a picture marked at heart by the notion of an inherently unequal struggle between forces of a different order and scale. Within this broad metaphor the only major difference of interpretation has reflected the competing theories of power in the international system developed by the realist and structuralist schools.

The mission of the Food and Drug Administration (FDA) is to promote public health by ensuring the safety and quality of food and medical products sold in the United States. At this year's annual Biotechnology Industry Organization (BIO) convention, significant discussion revolved around the appropriate interpretation and execution of that mission.The BIO meeting hosted 15 646 participants from across industry, government and the nonprofit sector, focusing on the current state of the biotechnology industry, as well as its challenges in seeking to further improve public welfare. Perhaps partly because this year's meeting was held in Washington, DC – the seat of the federal government and of BIO's headquarters – much attention was paid to the US regulatory environment. In particular, attendees debated the quandary faced every day by the FDA: how to enable access to novel therapies quickly, but only once their safety has been certified.
