The Impact

During the twenty-first century, the signature has been raised as an archetypical unit of account for the literacy of a group in a particular place, at a particular time. It also has been used as an index of the impact of the school network on the transmission of basic literacy skills. Nevertheless, a signature is everything but an historical invariant. To sign is a polysemical act with a history. It is a common practice that is tied to the juridical discourse and is socially connoted. This article intends to present some thoughts, from the New France history, upon contexts that can add value to the signature and have contributed to the infiltration of the written culture into the North American French colonial society before 1760.

Abstract The impact of future anthropogenic forcing on the frequency of tropical storms in the North Atlantic basin has been the subject of intensive investigation. However, whether the number of North Atlantic tropical storms will increase or decrease in a warmer climate is still heavily debated and a consensus has yet to be reached. To shed light on this issue, the authors use a recently developed statistical model, in which the frequency of North Atlantic tropical storms is modeled by a conditional Poisson distribution with rate of occurrence parameter that is a function of tropical Atlantic and mean tropical sea surface temperatures (SSTs). It is shown how the disagreement among dynamical modeling projections of late-twenty-first-century tropical storm frequency can be largely explained by differences in large-scale SST patterns from the different climate model projections used in these studies. The results do not support the notion of large (~200%) increases in tropical storm frequency in the North Atlantic basin over the twenty-first century in response to increasing greenhouse gases (GHGs). Because the statistical model is computationally inexpensive, it is used to examine the impact of different climate models and climate change scenarios on the frequency of North Atlantic tropical storms. The authors estimate that the dominant drivers of uncertainty in projections of tropical storm frequency over the twenty-first century are internal climate variations and systematic intermodel differences in the response of SST patterns to increasing GHGs. Relative to them, uncertainties in total GHG emissions or other climate forcings, within the scenarios explored here, represent a minor source of uncertainty in tropical storm frequency projections. These results suggest that reducing uncertainty in future projections of North Atlantic tropical storm frequency may depend as critically on reducing the uncertainty in the sensitivity of tropical Atlantic warming relative to the tropical mean, in response to GHG increase, as on improving dynamical or statistical downscaling techniques. Moreover, the large uncertainties on century-scale trends that are due to internal climate variability are likely to remain irreducible for the foreseeable future. As a further illustration of the statistical model’s utility, the authors model projected changes in U.S. landfalling tropical storm activity under a variety of different climate change scenarios and climate models. These results are similar to those for the overall number of North Atlantic tropical storms, and do not point to a large increase in U.S. landfalling tropical storms over the twenty-first century in response to increasing GHGs.

This short chapter contains three case studies: on Malta, Cyprus, and the South Caucasus. Given their respective locations on the southern and south-eastern extremities of Europe, all three have been subject to diverse and at times competing religious currents over many centuries. The impact of these currents needs careful interpretation. In the twenty-first century, Malta remains an actively Catholic society. Cyprus is still divided on ethno-religious lines: Turkish Cypriots are concentrated in the north and Greek Cypriots live in the south. The situation in the South Caucasus is more complex. It is shaped by a mixture of Western European, Russian, and Turkish references, but overall the region remains more a periphery of Europe than of Iran or Asia.

Abstract Regional climate change scenarios for Baja California/Southern California (BCC) and the North American monsoon (NAM) were produced as part of the Baja California State Climate Change Action Program (PEACC-BC). Bias-corrected and spatially downscaled scenarios (BCSD) from six general circulation models (GCMs) with a total of 12 realizations were analyzed for two scenarios of the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES): B1 (low emissions) and A2 (high emissions) during the twenty-first century. A validation of the original GCM realizations and the BCSD scenarios with observed data during 1961–90 show that the ensemble GCM produces too much precipitation during autumn and winter, which could be the cause of the observed delay of the summer monsoon rains; the ensemble BCSD considerably improves the mean annual cycles and spatial distributions of precipitation and temperature in the region. However, both ensembles greatly underestimate the observed interannual variability of precipitation. BCSD scenarios of temperature and precipitation during the twenty-first century were evaluated on the basis of the multimodel median change relative to 1961–90. The scenarios of precipitation change show large interannual variations and larger uncertainties than the scenarios of temperature change. The A2 scenarios show the largest reductions of precipitation in the last 20 yr of the twenty-first century; a decrease of 30% is projected for BCC mainly in winter and spring, while precipitation in the NAM region could be weakened by 20% during winter, spring, and summer. After 2050, a significant reduction of precipitation is expected in northwestern Mexico and the southwestern United States south of 35°N, and temperature changes larger than 2°C warming.

This Conclusion draws the study to a close, and recounts its developmental theses. The first thesis is that the complexity of positions on time (and space) defended in early modern thought is hugely under-appreciated. An enormous variety of positions were defended during this period, going far beyond the well-known absolutism–relationism debate. The second thesis is that during this period three distinct kinds of absolutism can be found in British philosophy: Morean, Gassendist, and Newtonian. The chapter concludes with a few notes on the impact of absolutism within and beyond philosophy: on twenty-first-century metaphysics of time; and on art, geology, and philosophical theology.

This paper represents the author’s view on the impact of the book Nonlinear Oscillations, Dynamical Systems and Bifurcations of Vector Fields by John Guckenheimer and Philip Holmes, first published in 1983 (Springer-Verlag, Berlin). In particular, the questions addressed are: if one were to write a similar book for the 21st century, which topics should be contained and what form should the book take in order to have a similar impact on the modern generation of young researchers in applied dynamical systems?

It is becoming increasingly clear that we are experiencing a shift in North American culture that requires the church to think of North America as mission field. The thesis of this article is that the church will need to develop a new paradigm of mission to accomplish this. This article identifies 18 issues which such a paradigm of mission will need to address. These issues are discussed in terms of three aspects: (1) the context in which we live, (2) the gospel we seek to proclaim, and (3) the church which seeks to proclaim this gospel.

Globalization, Nationalism, and Music Education in the Twenty-First Century in Greater China examines the recent developments in school education and music education in Greater China – Mainland China, Hong Kong, and Taiwan – and the relationship between, and integration of, national cultural identity and globalization in their respective school curriculums. Regardless of their common history and cultural backgrounds, in recent decades, these localities have experienced divergent political, cultural, and educational structures. Through an analysis of the literature, official curriculum documents, approved music textbooks, and a survey questionnaire and in-depth interviews with music teachers, this book also examines the ways in which policies for national identity formation and globalization interact to complement and contradict each other in the context of music education in respect to national and cultural values in the three territories. Wai-Chung Ho’s substantive research interests include the sociology of music, China’s education system, and the comparative study of East Asian music education. Her research focuses on education and development, with an emphasis on the impact of the interplay between globalization, nationalization, and localization on cultural development and school music education.

Abstract. The impact of large-scale circulation on urban gaseous elemental mercury (GEM) was investigated through analysis of 2008–2015 measurement data from an urban site in New York City (NYC), New York, USA. Distinct annual cycles were observed in 2009–2010 with mixing ratios in warm seasons (i.e. spring–summer) 10–20 ppqv (~ 10 %–25 %) higher than in cool seasons (i.e. fall–winter). This annual cycle was disrupted in 2011 by an anomalously strong influence of the North American trough in that warm season and was reproduced in 2014 with annual amplitude enhanced up to ~ 70 ppqv associated with a particularly strong Bermuda High. North American trough axis index (TAI) and intensity index (TII) were used to characterize the effect of the North American trough on NYC GEM especially in winter and summer. The intensity and position of the Bermuda High had a significant impact on GEM in warm seasons supported by a strong correlation (r reaching 0.96, p
