What influence will future solar activity changes over the 21st century have on projected global near-surface temperature changes?

During the 20th century, solar activity increased in magnitude to a so-called grand maximum. It is probable that this high level of solar activity is at or near its end. It is of great interest whether any future reduction in solar activity could have a significant impact on climate that could partially offset the projected anthropogenic warming. Observations and reconstructions of solar activity over the last 9000 years are used as a constraint on possible future variations to produce probability distributions of total solar irradiance over the next 100 years. Using this information, with a simple climate model, we present results of the potential implications for future projections of climate on decadal to multidecadal timescales. Using one of the most recent reconstructions of historic total solar irradiance, the likely reduction in the warming by 2100 is found to be between 0.06 and 0.1 K, a very small fraction of the projected anthropogenic warming. However, if past total solar irradiance variations are larger and climate models substantially underestimate the response to solar variations, then there is a potential for a reduction in solar activity to mitigate a small proportion of the future warming, a scenario we cannot totally rule out. While the Sun is not expected to provide substantial delays in the time to reach critical temperature thresholds, any small delays it might provide are likely to be greater for lower anthropogenic emissions scenarios than for higher-emissions scenarios.

American Challenges

In the autumn of 2008, with the United States facing myriad problems both foreign and domestic and entering the final stage of a historic election, The Boston Globe asked Mosakowski Institute Director Jim Gomes to write a series of op-ed pieces about critical issues on the nation’s agenda. The result is the six columns collected here in American Challenges. “When I wrote these pieces,” said Gomes, “the country had entered a period of great uncertainty. So much of what had been taken as a given in the last half of the 20th century, from broadly shared prosperity to the health of our political system to America’s place of leadership in the world, was being called into question.” These columns appeared in the Globe between October 27 and December 1, 2008. Together, they touch upon many enduring questions about the public enterprise in America.

Resonance of Unseen Things : Poetics, Power, Captivity, and UFOs in the American Uncanny /

'The Resonance of Unseen Things: Power, Poetics, Captivity and UFOs in the American Uncanny' offers an ethnographic meditation on the “uncanny” persistence and cultural freight of conspiracy theory. The project is a reading of conspiracy theory as an index of a certain strain of late-20th century American despondency/malaise, especially as experienced by people experiencing downward social mobility. Written by a cultural anthropologist with a literary background, this is a deeply interdisciplinary project that focuses on the enduring American preoccupation with captivity in a rapidly transforming world. Captivity is a trope that appears in both ordinary and fantastic iterations here, and this book shows how multiple troubled histories—of race, class, gender and power—become compressed into stories of uncanny memory.

Mad Men, The Sopranos and The American Way of Life. The history of the capital in two times

Don Draper (Mad Men, Matthew Weiner, AMC: 2007-2015) actively colaborates in the birth and consolidationof a model of consumer society without realizing the enormous lie he is telling himself. Tony Soprano(The Sopranos, David Chase, HBO: 1999-2007) desperately grasps the wreckage of that ideal imageof effort and self-improvement which is not only disappearing but was actually never coherent or real.This article does a comparative textual, sociological, and discursive analysis these two characters as arepresentation of the evolution of the discourse of capitalism in the second half of the 20th century, that is,the artificiality of the hegemonic discourse of “pursuit of happiness” as the main myth in post-war NorthAmerican neoliberalism.

THREE AMERICAN INTERNATIONAL PIANO COMPETITIONS: THE PIANO WORKS THEY COMMISSIONED BETWEEN 1962 AND 2012

Over a period of 50 years—between 1962 and 2012—three preeminent American piano competitions, the Van Cliburn International Piano Competition, the University of Maryland International Piano Competition/William Kapell International Piano Competition and the San Antonio International Piano Competition, commissioned for inclusion on their required performance lists 26 piano works, almost all by American composers. These compositions, works of sufficient artistic depth and technical sophistication to serve as rigorous benchmarks for competition finalists, constitute a unique segment of the contemporary American piano repertoire. Although a limited number of these pieces have found their way into the performance repertoire of concert artists, too many have not been performed since their premières in the final rounds of the competitions for which they were designed. Such should not be the case. Some of the composers in question are innovative titans of 20th-century American music—Samuel Barber, Aaron Copland, Leonard Bernstein, John Cage, John Corigliano, William Schuman, Joan Tower and Ned Rorem, to name just a few—and many of the pieces themselves, as historical touchstones, deserve careful examination. This study includes, in addition to an introductory overview of the three competitions, a survey of all 26 compositions and an analysis of their expressive characteristics, from the point of view of the performing pianist. Numerous musical examples support the analysis. Biographical information about the composers, along with descriptions of their overall musical styles, place these pieces in historical context. Analytical and technical comprehension of this distinctive and rarely performed corner of the modern classical piano world could be of inestimable value to professional pianists, piano pedagogues and music educators alike.

Knowledge-based urban development redefined : from theory to practice knowledge-based development of cities

The concept of knowledge-based urban development has first come to the urban planning and development agenda during the very last years of the 20th century as a promising paradigm to support the transformation process of cities into knowledge cities and their societies into knowledge societies. However, soon after the exponentially rapid advancements experienced, during the first decade of the 21st century, particularly, in the domains of economy, society, management and technology along with the severe impacts of climate change, have made the redefinition of the term a necessity. This paper, first, reports the findings of the review of the relatively short but dynamic history of urbanisation experiences of our cities around the globe. The paper, then, focuses on the 21st century urbanisation context and discusses the conceptual base of the knowledge-based development of cities and how this concept found application ground in many parts of the world. Following this, the paper speculates development of future cities by particularly highlighting potential challenges and opportunities that previously have not been fully considered. This paper, lastly, introduces and elaborates how relevant theories support the better conceptualisation of this relatively new, but rapidly emerging paradigm, and redefines it accordingly.

It’s not me, it’s you : a participant observation case study of the self-publishing musician in the 21st century

This thesis explores the business environment for self-publishing musicians at the end of the 20th century and the start of the 21st century from theoretical and empirical standpoints. The exploration begins by asking three research questions: what are the factors affecting the sustainability of an Independent music business; how many of those factors can be directly influenced by an Independent musician in the day-to-day operations of their musical enterprise; and how can those factors be best manipulated to maximise the benefit generated from digital music assets? It answers these questions by considering the nature of value in the music business in light of theories of political economy, then quantitative and qualitative examinations of the nature of participation in the music business, and then auto-ethnographic approaches to the application of two technologically enabled tools available to Independent musicians. By analyzing the results of five different examinations of the topic it answers each research question with reference to four sets of recurring issues that affect the operations of a 21st century music business: the musicians’ personal characteristics, their ability to address their business’s informational needs; their ability to manage the relationships upon which their business depends; and their ability to resolve the remaining technological problems that confront them. It discusses ways in which Independent self-publishing musicians can and cannot deal with these four issues on a day-to-day basis and highlights aspects for which technological solutions do not exist as well as ways in which technology is not as effective as has been claimed. It then presents a self-critique and proposes some directions for further study before concluding by suggesting some common features of 21st century Independent music businesses. This thesis makes three contributions to knowledge. First, it provides a new understanding of the sources of musical value, shows how this explains changes in the music industries over the past 30 years, and provides a framework for predicting future developments in those industries. Second, it shows how the technological discontinuity that has occurred around the start of the 21st century has and has not affected the production and distribution of digital cultural artefacts and thus the attitudes, approaches, and business prospects of Independent musicians. Third, it argues for new understandings of two methods by which self-publishing musicians can grow a business using production methods that are only beginning to be more broadly understood: home studio recording and fan-sourced production. Developed from the perspective of working musicians themselves, this thesis identifies four sets of issues that determine the probable success of musicians’ efforts to adopt new technologies to capture the value of the musicians’ creativity and thereby foster growth that will sustain an Independent music business in the 21st century.
