IAU Transactions XXVIB contains the Proceedings of the IAU XXVII General Assembly held in Prague, 14-25 August 2006, hosting a total of 2412 participants from 73 countries. The Assembly featured a rich scientific program, comprising 6 Symposia, 17 Joint Discussions and 7 Special Sessions. During the program about 650 papers were presented and more than 1550 posters displayed. The Proceedings of the 6 Symposia have been published in the Proceedings of the IAU Symposia Series, and the proceedings of the Joint Discussions and Special Sessions feature in IAU Highlights of Astronomy, 14. Together with those 7 volumes, these Transactions cover the entire General Assembly. In addition to the scientific program, the XXVI General Assembly hosted the regular Business Meetings of the EC, the 12 Divisions, 40 Commissions and 75 Working Groups. This volume records the organizational and administrative business of the XXVI General Assembly and the status of the IAU membership.

Astronomical discovery involves more than detecting something previously unseen. The reclassification of Pluto as a dwarf planet in 2006, and the controversy it generated, shows that discovery is a complex and ongoing process – one comprising various stages of research, interpretation and understanding. Ranging from Galileo's observation of Jupiter's satellites, Saturn's rings and star clusters, to Herschel's nebulae and the modern discovery of quasars and pulsars, Steven J. Dick's comprehensive history identifies the concept of 'extended discovery' as the engine of progress in astronomy. The text traces more than 400 years of telescopic observation, exploring how the signal discoveries of new astronomical objects relate to and inform one another, and why controversies such as Pluto's reclassification are commonplace in the field. The volume is complete with a detailed classification system for known classes of astronomical objects, offering students, researchers and amateur observers a valuable reference and guide.

How social scientists' disagreements about their key words and distinctions have been misconceived, and what to do about it Social scientists do research on a variety of topics—gender, capitalism, populism, and race and ethnicity, among others. They make descriptive and explanatory claims about empathy, intelligence, neoliberalism, and power. They advise policymakers on diversity, digitalization, work, and religion. And yet, as Gabriel Abend points out in this provocative book, they can’t agree on what these things are and how to identify them. How to tell if something is a religion or a cult or a sect? What is empathy? What makes this society a capitalist one? Disputes of this sort arise again and again in the social sciences. Abend argues that these disagreements have been doubly misconceived. First, they conflate two questions: how a social science community should use its most important words, and what distinctions it should accept and work with. Second, there’s no fact of the matter about either. Instead, they’re practical reason questions for a community, which aim at epistemically and morally good outcomes. Abend calls on social science communities to work together on their words, distinctions, and classifications. They must make collective decisions about the uses of words, the acceptability of distinctions, and the criteria for assessing both. These decisions aren’t up to individual scholars; the community gets the last word. According to Abend, the common good, justice, and equality should play a significant role in the logic of scientific research. Gabriel Abend is professor of sociology at University of Lucerne and the author of The Moral Background: An Inquiry into the History of Business Ethics (Princeton).

Most subfields of computer science have an interface layer via which applications communicate with the infrastructure, and this is key to their success (e.g., the Internet in networking, the relational model in databases, etc.). So far this interface layer has been missing in AI. First-order logic and probabilistic graphical models each have some of the necessary features, but a viable interface layer requires combining both. Markov logic is a powerful new language that accomplishes this by attaching weights to first-order formulas and treating them as templates for features of Markov random fields. Most statistical models in wide use are special cases of Markov logic, and first-order logic is its infinite-weight limit. Inference algorithms for Markov logic combine ideas from satisfiability, Markov chain Monte Carlo, belief propagation, and resolution. Learning algorithms make use of conditional likelihood, convex optimization, and inductive logic programming. Markov logic has been successfully applied to problems in information extraction and integration, natural language processing, robot mapping, social networks, computational biology, and others, and is the basis of the open-source Alchemy system.

This book represents Volume II of the Proceedings of the UN/ESA/NASA Workshop on the International Heliophysical Year 2007 and Basic Space Science, hosted by the National Astronomical Observatory of Japan, Tokyo, 18 - 22 June, 2007. It covers two programme topics explored in this and past workshops of this nature: (i) non-extensive statistical mechanics as applicable to astrophysics, addressing q-distribution, fractional reaction and diffusion, and the reaction coefficient, as well as the Mittag-Leffler function and (ii) the TRIPOD concept, developed for astronomical telescope facilities. The companion publication, Volume I of the proceedings of this workshop, is a special issue in the journal Earth, Moon, and Planets, Volume 104, Numbers 1-4, April 2009.

A groundbreaking scholarly publication, accompanying an exhibition organized by the National Museum of African Art, Smithsonian Institution, African Cosmos: Stellar Arts brings together exceptional works of art, dating from ancient times to the present, and essays by leading scholars and contemporary artists to consider African cultural astronomy: creativity and artistic practice in Africa as it is linked to celestial bodies and atmospheric phenomena. African concepts of the universe are intensely personal, placing human beings in relation to the earth and sky, and with the sun, moon, and stars. At the core of creation myths and the foundation of moral values, celestial bodies are often accorded sacred capacities and are part of the “cosmological map” that allows humans to chart their course through life.
