The plural form 'Englishes' conveys the diversity of English as a global language, pinpointing the growth and existence of a large number of national, regional and social forms. The global spread of English and the new varieties that have emerged around the world has grown to be a vast area of study and research, which intersects multiple disciplines. This Handbook provides a comprehensive and authoritative survey of World Englishes from 1600 to the present day. Covering topics such as variationist sociolinguistics, pragmatics, contact linguistics, linguistic anthropology, corpus- and applied linguistics and language history, it combines discussion of traditional topics with a variety of innovative approaches. The chapters, all written by internationally acclaimed authorities, provide up-to-date discussions of the evolution of different Englishes around the globe, a comprehensive coverage of different models and approaches, and some original perspectives on current challenges.
In recent years, the discovery of massive quasars at
has provided a striking challenge to our understanding of the origin and growth of supermassive black holes in the early Universe. Mounting observational and theoretical evidence indicates the viability of massive seeds, formed by the collapse of supermassive stars, as a progenitor model for such early, massive accreting black holes. Although considerable progress has been made in our theoretical understanding, many questions remain regarding how (and how often) such objects may form, how they live and die, and how next generation observatories may yield new insight into the origin of these primordial titans. This review focusses on our present understanding of this remarkable formation scenario, based on the discussions held at the Monash Prato Centre from November 20 to 24, 2017, during the workshop ‘Titans of the Early Universe: The Origin of the First Supermassive Black Holes’.
Three states and one county now allow Emergency Medical Services (EMS) providers to transport injured law enforcement K9s (LEK9s) as long as no human needs the ambulance at the time. Several other states either have pending legislation or are in discussions about this topic. As additional states ponder these laws, it is likely that the EMS transport of LEK9s will become legal in many states. In the wake of this legislation, a significant void was created. Currently, there are no published protocols for the safe transport of LEK9s by EMS providers. Additionally, the transport destination for these LEK9s is unlikely to be programmed into vehicle Global Positioning Systems. The authors of this report convened a Joint Task Force on Working Dog Care, consisting of veterinarians, EMS directors, EMS physicians, and LEK9 handlers, who met to develop a protocol for LEK9s being transported to a veterinary facility. The protocol covers the logistics of getting the LEK9 into the ambulance (eg, when the handler is or is not available), appropriate restraint, and the importance of prior arrangements with a veterinary emergency facility. A LEK9 hand-off form and a Transport Policy Form are provided, downloadable, and customizable for each EMS provider. This protocol provides essential information on safety and transport logistics for injured LEK9s. The hope is that this protocol will assist EMS providers to streamline the transport of an injured LEK9 to an appropriate veterinary facility.
This document is a resource for Emergency Medical Services (EMS) treating an injured law enforcement K9 (LEK9) in the field and/or during transport by ambulance to a veterinary hospital. A Joint Task Force on Working Dog Care was created, which included veterinarians, EMS directors, EMS physicians, and canine handlers, who met to develop a treatment protocol for injured LEK9s. The protocol covers many major life-threatening injuries that LEK9s may sustain in the line of duty, and also discusses personnel safety and necessary equipment. This protocol may help train EMS providers to save the life of an injured LEK9.
A lasting legacy of the International Polar Year (IPY) 2007–2008 was the promotion of the Permafrost Young Researchers Network (PYRN), initially an IPY outreach and education activity by the International Permafrost Association (IPA). With the momentum of IPY, PYRN developed into a thriving network that still connects young permafrost scientists, engineers, and researchers from other disciplines. This research note summarises (1) PYRN’s development since 2005 and the IPY’s role, (2) the first 2015 PYRN census and survey results, and (3) PYRN’s future plans to improve international and interdisciplinary exchange between young researchers. The review concludes that PYRN is an established network within the polar research community that has continually developed since 2005. PYRN’s successful activities were largely fostered by IPY. With >200 of the 1200 registered members active and engaged, PYRN is capitalising on the availability of social media tools and rising to meet environmental challenges while maintaining its role as a successful network honouring the legacy of IPY.
Shallow ice cores were obtained from widely distributed sites across the West Antarctic ice sheet, as part of the United States portion of the International Trans-Antarctic Scientific Expedition (US ITASE) program. The US ITASE cores have been dated by annual-layer counting, primarily through the identification of summer peaks in non-sea-salt sulfate (nssSO42–) concentration. Absolute dating accuracy of better than 2 years and relative dating accuracy better than 1 year is demonstrated by the identification of multiple volcanic marker horizons in each of the cores, Tambora, Indonesia (1815), being the most prominent. Independent validation is provided by the tracing of isochronal layers from site to site using high-frequency ice-penetrating radar observations, and by the timing of mid-winter warming events in stable-isotope ratios, which demonstrate significantly better than 1 year accuracy in the last 20 years. Dating precision to ±1 month is demonstrated by the occurrence of summer nitrate peaks and stable-isotope ratios in phase with nssSO42–, and winter-time sea-salt peaks out of phase, with phase variation of <1 month. Dating precision and accuracy are uniform with depth, for at least the last 100 years.
This paper reports on a theoretical analysis of the rich variety of spatio-temporal patterns observed recently in inclined layer convection at medium Prandtl number when varying the inclination angle
and the Rayleigh number
. The present numerical investigation of the inclined layer convection system is based on the standard Oberbeck–Boussinesq equations. The patterns are shown to originate from a complicated competition of buoyancy driven and shear-flow driven pattern forming mechanisms. The former are expressed as longitudinal convection rolls with their axes oriented parallel to the incline, the latter as perpendicular transverse rolls. Along with conventional methods to study roll patterns and their stability, we employ direct numerical simulations in large spatial domains, comparable with the experimental ones. As a result, we determine the phase diagram of the characteristic complex 3-D convection patterns above onset of convection in the
plane, and find that it compares very well with the experiments. In particular we demonstrate that interactions of specific Fourier modes, characterized by a resonant interaction of their wavevectors in the layer plane, are key to understanding the pattern morphologies.
Placebo responses raise significant challenges for the design of clinical trials. We report changes in agitation outcomes in the placebo arm of a recent trial of citalopram for agitation in Alzheimer's disease (CitAD).
In the CitAD study, all participants and caregivers received a psychosocial intervention and 92 were assigned to placebo for nine weeks. Outcomes included Neurobehavioral Rating Scale agitation subscale (NBRS-A), modified AD Cooperative Study-Clinical Global Impression of Change (CGIC), Cohen-Mansfield Agitation Inventory (CMAI), the Neuropsychiatric Inventory (NPI) Agitation/Aggression domain (NPI A/A) and Total (NPI-Total) and ADLs. Continuous outcomes were analyzed with mixed-effects modeling and dichotomous outcomes with logistic regression.
Agitation outcomes improved over nine weeks: NBRS-A mean (SD) decreased from 7.8 (3.0) at baseline to 5.4 (3.2), CMAI from 28.7 (6.7) to 26.7 (7.4), NPI A/A from 8.0 (2.4) to 4.9 (3.8), and NPI-Total from 37.3 (17.7) to 28.4 (22.1). The proportion of CGI-C agitation responders ranged from 21 to 29% and was significantly different from zero. MMSE improved from 14.4 (6.9) to 15.7 (7.2) and ADLs similarly improved. Most of the improvement was observed by three weeks and was sustained through nine weeks. The major predictor of improvement in each agitation measure was a higher baseline score in that measure.
We observed significant placebo response which may be due to regression to the mean, response to a psychosocial intervention, natural course of symptoms, or nonspecific benefits of participation in a trial.
One of the Drake Equation factors that has changed the most since 1961 is ne, the average number of planets per star that can potentially support life. This factor is still evolving.
The definition of conditions for developing life is related to the definition of a circumstellar habitable zone. It is generally defined as the zone in which physical conditions make presence of liquid water possible. As a first approximation, it implies a temperature between 0 and 100 degrees Celsius, the so-called Goldilocks condition. This preliminary estimate is based on the temperature of the star: in other words, its spectral type and the distance between the star and its planet. Changes in the ne term are principally due to unexpected characteristics on one hand of many exoplanets and on the other hand of some objects in the solar system.
We first discuss the basic condition for life: liquid water. Stellar spectral types where life is most likely to emerge and exist are reviewed, and less favorable conditions of hot and cold stars are discussed. We also look at planets orbiting one member of a binary star, or around both stars (“circumbinary planets”). We point out the physical conditions necessary for planets to shelter life, including mass and other physical parameters. Exomoons are interesting objects and are discussed as well. Relations between the star and its planetary system are reviewed. No longer is distance the only parameter to be considered. In the case of terrestrial exoplanets with large eccentricity that cross the habitable zone, life with some phases of hibernation may be possible. Some terrestrial exoplanets orbit so close to their star that they are co-rotating, keeping one face to the star at all times, which implies that a temperate annular zone may exist between the very 115hot face in front of the star and the very cold face on the opposite side. Characteristics of some satellites in the solar system discovered since the space age show that some tidal effects are liable to extend the habitable zone, as can be seen by the detection of oceans flowing below the icy surface of Europa or internal water springing from the geysers of Enceladus. It would be interesting to search for and study as a source of possible life moons of giant exoplanets located in the habitable zone of their star. As a conclusion, the continuously increasing number of small rocky planets provides great encouragement to search for extraterrestrial life. Indeed, they show a high rate per star and satisfy the conditions necessary for producing life.
This volume follows on from The Lesser-Known Varieties of English (Cambridge, 2010), by documenting a further range of varieties that have been overlooked and understudied. It explores varieties spoken by small groups of people in remote regions as diverse as Malta, Bermuda, the Netherlands Antilles, Brazil, the Cook Islands, and Palau. The varieties explored are as much a part of the big picture as major varieties and it is the intention of this collection to spark further interest in the sociolinguistic documentation of minority Englishes in a postcolonial world. Language endangerment is a very real factor for the vast majority of lesser-known varieties of English, and this book aims to highlight that documentation and archiving are key initial steps in revitalization and reclamation efforts. This book will be of interest to historians of English, and scholars in dialectology, language birth and death, language contact, typology, and variation and change.
