Micro- and macro-variation of causal clauses : synchronic and diachronic insights
This collection presents novel insights into the micro- and macro-variation of causal clauses from a cross-linguistic perspective. It contains a general introduction to the topic setting the scene, and nine chapters based on data from Dutch, German, English, Icelandic, Chinese, and Japanese.
Myanmar in crisis : living with the pandemic and the coup
Myanmar in Crisis brings together scholars from across the social sciences to analyse the dual crises of COVID-19 and the 2021 military coup. All of the essays address one of four themes around the concept of crisis: society in crisis, a state in crisis, an economy in crisis, and international relations in crisis. Several authors examine the contested nature of state authority in the post-coup revolutionary context, including the emergence of new governance dynamics; others discuss heterogenous forms of resistance and the potential for building a more inclusive, just, and tolerant society in the future of Myanmar. The volume also explores the economic crisis caused by the pandemic and the coup and its devastating effects on people's lives and livelihoods: the authors provide a deep dive into the impacts of restrictive COVID-19 prevention measures on local communities, the growing livelihoods crisis since the coup, and the impacts of both crises on foreign trade and investment. Scaling up from that local perspective, the book also looks at Myanmar's history of foreign relations, the response of the international community to the coup and the challenges faced by foreign governments and regional bodies in navigating the deteriorating political situation. Held together, the volume highlights the ongoing state of crisis in Myanmar, its impact on society and the possibilities for recovery and reform, amidst a powerful new revolutionary movement. Beyond providing crucial insights to Southeast Asian area specialists, the book offers deep insights into the way that multiple crises interact, amplify one another, and open up possibilities for hope amidst tragedy.
Ancient Egyptian and Afroasiatic
By challenging assumptions regarding the proximity between Egyptian and Semitic Languages, Ancient Egyptian and Afroasiatic provides a fresh approach to the relationships and similarities between Ancient Egyptian, Semitic, and Afroasiatic languages. This in-depth analysis includes a re-examination of the methodologies deployed in historical linguistics and comparative grammar, a morphological study of Ancient Egyptian, and critical comparisons between Ancient Egyptian and Semitic, as well as careful considerations of environmental factors and archaeological evidence. These contributions offer a reassessment of the Afroasiatic phylum, which is based on the relations between Ancient Egyptian and the other Afroasiatic branches. This volume illustrates the advantages of viewing Ancient Egyptian in its African context. In addition to the editors, the contributors to this collection include Shiferaw Assefa, Michael Avina, Vit Bubenik, Leo Depuydt, Christopher Ehret, Zygmunt Frajzyngier, J. Lafayette Gaston, Tiffany Gleason, John Huehnergard, Andrew Kitchen, Elsa Oréal, Chelsea Sanker, Lameen Souag, Andréas Stauder, Deven N. Vyas, Aren Wilson-Wright, and Jean Winand.
Marine20—The Marine Radiocarbon Age Calibration Curve (0–55,000 cal BP)
The concentration of radiocarbon (14C) differs between ocean and atmosphere. Radiocarbon determinations from samples which obtained their 14C in the marine environment therefore need a marine-specific calibration curve and cannot be calibrated directly against the atmospheric-based IntCal20 curve. This paper presents Marine20, an update to the internationally agreed marine radiocarbon age calibration curve that provides a non-polar global-average marine record of radiocarbon from 0–55 cal kBP and serves as a baseline for regional oceanic variation. Marine20 is intended for calibration of marine radiocarbon samples from non-polar regions; it is not suitable for calibration in polar regions where variability in sea ice extent, ocean upwelling and air-sea gas exchange may have caused larger changes to concentrations of marine radiocarbon. The Marine20 curve is based upon 500 simulations with an ocean/atmosphere/biosphere box-model of the global carbon cycle that has been forced by posterior realizations of our Northern Hemispheric atmospheric IntCal20 14C curve and reconstructed changes in CO2 obtained from ice core data. These forcings enable us to incorporate carbon cycle dynamics and temporal changes in the atmospheric 14C level. The box-model simulations of the global-average marine radiocarbon reservoir age are similar to those of a more complex three-dimensional ocean general circulation model. However, simplicity and speed of the box model allow us to use a Monte Carlo approach to rigorously propagate the uncertainty in both the historic concentration of atmospheric 14C and other key parameters of the carbon cycle through to our final Marine20 calibration curve. This robust propagation of uncertainty is fundamental to providing reliable precision for the radiocarbon age calibration of marine based samples. We make a first step towards deconvolving the contributions of different processes to the total uncertainty; discuss the main differences of Marine20 from the previous age calibration curve Marine13; and identify the limitations of our approach together with key areas for further work. The updated values for ΔR, the regional marine radiocarbon reservoir age corrections required to calibrate against Marine20, can be found at the data base http://calib.org/marine/.
SHCal20 Southern Hemisphere Calibration, 0–55,000 Years cal BP
Early researchers of radiocarbon levels in Southern Hemisphere tree rings identified a variable North-South hemispheric offset, necessitating construction of a separate radiocarbon calibration curve for the South. We present here SHCal20, a revised calibration curve from 0–55,000 cal BP, based upon SHCal13 and fortified by the addition of 14 new tree-ring data sets in the 2140–0, 3520–3453, 3608–3590 and 13,140–11,375 cal BP time intervals. We detail the statistical approaches used for curve construction and present recommendations for the use of the Northern Hemisphere curve (IntCal20), the Southern Hemisphere curve (SHCal20) and suggest where application of an equal mixture of the curves might be more appropriate. Using our Bayesian spline with errors-in-variables methodology, and based upon a comparison of Southern Hemisphere tree-ring data compared with contemporaneous Northern Hemisphere data, we estimate the mean Southern Hemisphere offset to be 36 ± 27 14C yrs older.
The IntCal20 Northern Hemisphere Radiocarbon Age Calibration Curve (0–55 cal kBP)
Radiocarbon (14C) ages cannot provide absolutely dated chronologies for archaeological or paleoenvironmental studies directly but must be converted to calendar age equivalents using a calibration curve compensating for fluctuations in atmospheric 14C concentration. Although calibration curves are constructed from independently dated archives, they invariably require revision as new data become available and our understanding of the Earth system improves. In this volume the international 14C calibration curves for both the Northern and Southern Hemispheres, as well as for the ocean surface layer, have been updated to include a wealth of new data and extended to 55,000 cal BP. Based on tree rings, IntCal20 now extends as a fully atmospheric record to ca. 13,900 cal BP. For the older part of the timescale, IntCal20 comprises statistically integrated evidence from floating tree-ring chronologies, lacustrine and marine sediments, speleothems, and corals. We utilized improved evaluation of the timescales and location variable 14C offsets from the atmosphere (reservoir age, dead carbon fraction) for each dataset. New statistical methods have refined the structure of the calibration curves while maintaining a robust treatment of uncertainties in the 14C ages, the calendar ages and other corrections. The inclusion of modeled marine reservoir ages derived from a three-dimensional ocean circulation model has allowed us to apply more appropriate reservoir corrections to the marine 14C data rather than the previous use of constant regional offsets from the atmosphere. Here we provide an overview of the new and revised datasets and the associated methods used for the construction of the IntCal20 curve and explore potential regional offsets for tree-ring data. We discuss the main differences with respect to the previous calibration curve, IntCal13, and some of the implications for archaeology and geosciences ranging from the recent past to the time of the extinction of the Neanderthals.
Crossing Borders, Writing Texts, Being Evaluated
This book provides critical perspectives on issues relating to writing norms and assessment, as well as writing proficiency development, and suggests that scholars need to both carefully examine testing regimes and develop research-informed perspectives on tests and testing practices. In this way schools, institutions of adult education and universities can better prepare learners with differing cultural experiences to meet the challenges. The book brings together empirical studies from diverse geographical contexts to address the crossing of literacy borders, with a focus on academic genres and practices. Most of the studies examine writing in countries where the norms and expectations are different, but some focus on writing in a new discourse community set in a new discipline. The chapters shed light on commonalities and differences between these two situations with respect to the expectations and evaluations facing the writers. They also consider the extent to which the norms that the writers bring with them from their educational backgrounds and own cultures are compromised in order to succeed in the new educational settings.
