Abstract The Geostationary Operational Environmental Satellite-14 (GOES-14) imager was operated by the National Oceanic and Atmospheric Administration (NOAA) in an experimental rapid scan 1-min mode during parts of the summers of 2012 and 2013. This scan mode, known as the super rapid scan operations for GOES-R (SRSOR), emulates the high-temporal-resolution sampling of the mesoscale region scanning of the Advanced Baseline Imager (ABI) on the next-generation GOES-R series. This paper both introduces these unique datasets and highlights future satellite imager capabilities. Many phenomena were observed from GOES-14, including fog, clouds, severe storms, fires and smoke (including the California Rim Fire), and several tropical cyclones. In 2012 over 6 days of SRSOR data of Hurricane Sandy were acquired. In 2013, the first two days of SRSOR in June observed the propagation and evolution of a mid-Atlantic derecho. The data from August 2013 were unique in that the GOES imager operated in nearly continuous 1-min mode; prior to this time, the 1-min data were interrupted every 3 h for full disk scans. Used in a number of NOAA test beds and operational centers, including NOAA’s Storm Prediction Center (SPC), the Aviation Weather Center (AWC), the Ocean Prediction Center (OPC), and the National Hurricane Center (NHC), these experimental data prepare users for the next-generation imager, which will be able to routinely acquire mesoscale (1,000 km × 1,000 km) images every 30 s (or two separate locations every minute). Several animations are included, showcasing the rapid change of the many phenomena observed during SRSOR from the GOES-14 imager.

Abstract The Geostationary Operational Environmental Satellite-14 (GOES-14) Imager was operated by the National Oceanic and Atmospheric Administration (NOAA) in an experimental rapid scan 1-min mode during parts of 2012, 2013, 2014, and 2015. This scan mode, known as the Super Rapid Scan Operations for GOES-R (SRSOR), emulates the high-temporal-resolution sampling that will be provided by the Advanced Baseline Imager on the next-generation GOES-R series. NOAA/National Weather Service/Storm Prediction Center (SPC) forecasters utilized the 1-min imagery extensively in operations when available over convectively active regions. They found it provided them with unique insight into relevant features and processes before, during, and after convective initiation. This paper introduces how the SRSOR datasets from GOES-14 were used by SPC forecasters and how these data are likely to be applied when available operationally from GOES-R. Several animations, included as supplemental material, showcase the rapid change of severe weather–related phenomena observed during the 2014 and 2015 SRSOR campaigns from the GOES-14 Imager.

AbstractThe Arctic Ocean is undergoing rapid change: sea ice is being lost, waters are warming, coastlines are eroding, species are moving into new areas, and more. This paper explores the many ways that a changing Arctic Ocean affects societies in the Arctic and around the world. In the Arctic, Indigenous Peoples are again seeing their food security threatened and cultural continuity in danger of disruption. Resource development is increasing as is interest in tourism and possibilities for trans-Arctic maritime trade, creating new opportunities and also new stresses. Beyond the Arctic, changes in sea ice affect mid-latitude weather, and Arctic economic opportunities may re-shape commodities and transportation markets. Rising interest in the Arctic is also raising geopolitical tensions about the region. What happens next depends in large part on the choices made within and beyond the Arctic concerning global climate change and industrial policies and Arctic ecosystems and cultures.

This article sets out to present a new imagery for capturing the power and potential of Olympism in attempting to educate the next generation of sport consumers and decision makers. It is hoped that the new imagery can make a contribution on how to moderate and regulate the rampant commodification of sport. This new imagery begins with the need for physical educators to open their minds and instigate a critical orientation to thinking about sport and Olympic matters. It is argued that doing this might help in the creation of new possibilities and visions for Olympism and sport and allow us to confront some of the disagreeable contemporary concerns in sport that scholars have identified. The new imagery for Olympism is based on the development of a critical pedagogy that draws on the works of Apple, Freire and Kincheloe, and is re-contextualised for school physical education and sports programmes. It is concluded that decisions, behaviours and actions that are made at present actually propagate many of the policies that will be made tomorrow. It is argued that a critical pedagogy for Olympism is needed to address the many current disagreeable aspects of sport.

The many unexplained phenomena attending the passage of electricity through gases will probably for some time to come occupy the attention of experimental physicists. It is desirable that the subject should be approached from as many different sides as possible. One of our most powerful instruments of research is the spectroscope; but before it can be applied to the study in question, we have to settle the chemical origin of the different spectra which we observe in tubes, and to discuss in what way such spectra are liable to change under different circumstances. A special investigation has to be made for each gas; we have to study the effect of various impurities, the influence of the electrodes and that of the glass, which in the tubes generally used is considerably heated up by the spark. To make the investigation complete we have to vary as much as possible the pressure, the bore of the vacuum tube, and the strength of the spark. I have chosen Oxygen as a first subject of investigation. Though Plücker and Wüllner have, as far as their experiments went, accurately described the phenomena seen in oxygen tubes, the following paper contains much that is new, and will put some of the older facts on a firmer basis. When I first began to work, it was my intention to take the gases in groups, and to study their mixture; but as the following investigation has taken me a year’s nearly continuous work, and is complete in itself, I trust it will not be found unworthy of publication. I must, of course, at present confine myself to the purely spectroscopic point of view. As several of the observations which I shall have to record bear directly on the general theory of double spectra, I must briefly refer to our knowledge on that point.

The theme of the 2018 American Association of Neurological Surgeons Annual Meeting was “The Privilege of Service.” In the current climate of rapid change in healthcare delivery and increasing pressure on physicians, this theme was chosen to remind us of our true priorities and of the amazing opportunities that we have as neurosurgeons. In parallel to the classic triple-threat practitioner who excels in teaching, research, and clinical care, future neurosurgeons will need to acquire mastery in three areas of service, which have been summarized as the three A’s: administration, advocacy, and altruism. The blessings that we enjoy afford us a platform from which we can take advantage of the many opportunities to experience the privilege of serving others.

In 2016, the Nottingham group detected the rotational superradiance effect. While this experiment demonstrated the robustness of the superradiance process, it still lacks a complete theoretical description due to the many effects at stage in the experiment. In this paper, we shine new light on this experiment by deriving an estimate of the reflection coefficient in the dispersive regime by means of a Wentzel–Kramers–Brillouin analysis. This estimate is used to evaluate the reflection coefficient spectrum of counter-rotating modes in the Nottingham experiment. Our finding suggests that the vortex flow in the superradiance experiment was not purely absorbing, contrary to the event horizon of a rotating black hole. While this result increases the gap between this experimental vortex flow and a rotating black hole, it is argued that it is in fact this gap that is the source of novel ideas. This article is part of a discussion meeting issue ‘The next generation of analogue gravity experiments’.

Abstract In general, the biographical dictionary is usually described as the purview of the history of a religion’s approach to encyclopaedic life-narratives. Biographies of the Prophet Muhammad, his Companions and other scholars have all been written with the intention of increasing Islamic faithfulness and piety. While illuminating or phenomenological studies of a few features of Islamic biographical writing exist, there is a need for a more analytical survey to show how biographical appearances evolved and developed. This article undertakes an exploratory analysis of ḥadīṯ scholars’ biographical dictionaries around the second/eight and third/ninth centuries as presented in their works. Apart from the scholarly trend and prevalent religious notions of the time, it will highlight this generation’s contribution and role to the field of Islamic scholarship as well as the influence upon the next generation. The many sub-genres of biographical dictionaries of ḥadīṯ transmitters that are presented in this article were composed over the first three Centuries of Islam and are celebrated as a result of this advancement in Islamic literature.

The Internet has become a major part of the global communications infrastructure supporting modern-day socio-economic development, social progress and technological innovation. Invented 30 years ago, today the Internet is facing severe challenges. Many countries have funded research projects on the new-generation Internet, such as GENI, FIND, FIRE and CNGI, in an effort to solve these challenges. In addition, over the past few years, the networking research community has engaged in an ongoing conversation about how to move the Internet forward, and there are now two different approaches towards Internet research. The first approach is based on using the existing Internet architecture to solve the major technical challenges—this is called ‘evolutionary’ research. The other, which is called the ‘clean slate’, involves the design of an entirely new Internet architecture. In the first part of this paper, the basic features of the next generation Internet and its principal contradictions are analysed. Then a survey of recent progress in the study of the next generation Internet in China is discussed. Finally, the focus and direction for the next step in research are presented as based on fundamental research into the international next generation Internet architecture, and the many new innovative demands placed on Internet architecture in recent years.

The first half of the nineteenth century in Great Britain was one of nearly continuous controversy over monetary issues. The Restriction of Cash Payments and the Bullion Controversy dominated the first two decades. After Resumption in 1821, a series of banking crises kept monetary issues on the front burner, until they boiled over again in the Currency-Banking Controversy of the 1840s. Of the many writers contributing to the monetary literature during the period, few contributed so much as Thomas Tooke. Long recognized as a collector of economic data without peer in his era, Tooke's reputation as an economic theorist has grown in recent years (cf. Laidler 1972; Arnon 1991; M. Smith 2001). Readers of Tooke's works have long known that his views on monetary theory changed radically from the 1820s to the 1840s, when he adopted a starkly anti-quantity theory approach. In his early years as a collector of economic data, Tooke allied himself with David Ricardo in the effort to return Great Britain to the gold standard. But though both subscribed to the quantity-theory/price-specie-flow-mechanism (QT-PSFM) framework for analyzing the economy's adjustment to monetary disturbances, their theoretical approaches differed in important respects. The differences were great enough to lead Arnon (1989, 1991) to conclude that Tooke and Ricardo should be viewed primarily as political, not theoretical, allies and to suggest that Tooke's approach shared greater affinities with the work of moderate bullionists than with Ricardo (Arnon 1991, pp. 48, 58, 108).
