H.T. MacGilLIVRAY Royal Observatory Blackford Hill Edinburgh EH9 3HJ Scotland U.K. lAU Symposium No. 161 on 'Astronomy from Wide-Field Imaging', held in Potsdam, Germany, during 23-27th August 1993, was the first conference organised by the recently-formed Working Group of lAU Commission 9 on 'Wide-Field Imaging'. This Working Group was instigated during the XXIst meeting of the General Assembly of the International Astronomical Union in Buenos Aires in 1991, and represented a merging of the former formal lAU Working Group on 'Astronomical Photography' and the informal 'Digitised Optical Sky Surveys' Working Group. Dr. Richard West was 'invited' to be Chairperson, and hence was given the daunting task of organising the Group from scratch. The very fact that the first conference after only two years was a major lAU Symposium says much about the determination and enthusiasm of Richard West to fulfilling the aims of the new Working Group. The siting of the conference in Potsdam in formerly East Germany provided an excellent opportunity to advantage from the political changes in Eastern Europe. Good access to the meeting was possible by scientists from Eastern European countries, allowing exchange of information on the very important Wide-Field facilities in both East and West, information on the rich archives of photographic plates that exist in both East and West, and allowing discussions between scientists facing very similar problems in both East and West.

Darrell M. West explores leadership and and coalition-building in the 1980 presidential campaign. Concentrating upon the candidates' own perceptions of the need to build coalitions that will elect them, he raises questions that go to the heart of presidential politics: how have changes in presidential campaigns influenced candidate strategies? what coalitions did presidential contenders try to put together? how did the candidates use rhetoric, campaign travel, and symbolism in their coalition building? what did candidates learn from their audiences in their months and years on the campaign trail? what do these lessons imply for political leadership and coalition building? To answer these questions, he draws on interviews with ninety advisors to candidates and on data taken from the candidates' travels and speeches, press coverage, and audience reactions. His findings reveal a surprising consistency in the approach to building an electoral majority.

Even the casual reader cannot fail to notice the somewhat uneven presentation of the contributions contributians to this volume, in particular what concerns the st style. yle. A closer scrutiny will also reveal that whereas the English language is certainly the preferred vehicle for commu- nication in astronomy, it is not the mother tongue of all contributors. However, while editing this volume I have felt that it would be more important to assure a speedy publication than to attempt to achieve a high degree of uniformity, which would anyhow be extremely diffi- cult with more than 100 eontributing contributing authors. When published, this book should stiIl still be a tool for aetive active research, not a museum pieee. piece. I am grateful to the organizers and editors of the individual sections seetions for having produced produeed their parts with within in the allotted time, and with a high degree of professionalism. A special speeial word of thanks goes to my eollaborators collaborators at the European Southern Observatory, Mrs. E. Volk, Volk, Mr. Nr. C. Madsen, and Mr. J. _Leelereqz, _Leclercqz, for technical teehnieal assistanee. assistance.

The XVlllth General Assembly of the International Astronomical Union was held in Patras, Greece, from 17-26 August 1982. It was marked by the tragic death of the President of the IAU, Professor M.K.V. Bappu, on August 19, 1982. This sad event, without precedent in the history of the Union, posed serious problems to the organization of the General Assembly, which could only be overcome by the full collaboration of all members, the organizers, and the Executive Committee. A tribute to the memory of Prof. Bappu was paid during a plenary meeting on 23 August 1982. The full texts of the speeches are published in Chapter I of this . volume. The excellent scientific programme in Patras was organized by the Presidents of the 40 IAU Commissions and coordinated by the IAU General Secretary (1979-1982), Professor P.A. Wayman. The local arrangements were taken care of by Professor C. Goudas and his collaborators from the Patras University. Due to the unexpected withdrawal in 1979 of another invitation to host the 1982 IAU General Assembly, the organizers in Greece had less than two years available for the extensive preparations, and our hearty thanks are due to them for their persistent efforts, which made this General Assembly an outstanding success.

Astronomy on the Personal Computer provides the reader with a thorough introduction to the computation of celestial mechanics, which is of particular significance to astronomical observation. Covering everything from astronomical and computational theory to the construction of rapid and accurate applications programs, this book supplies the necessary knowledge and software solutions for determining and predicting the positions of the Sun, Moon, planets, minor planets and comets, solar eclipses, stellar occultations by the Moon, phases of the Moon and much more. This completely revised edition makes use of the widely implemented programming language C++, and individual applications may be efficiently realized through the use of a powerful module library. The accompanying CD-ROM contains, in addition to the complete, fully documented and commented source codes, the executable programs for use with the Windows 95/98/NT and Linux operating systems.

The Transgender Athlete: A Guide for Sports Medicine Providers presents sports medicine practitioners insights into the unique issues and concerns of transgender athletes in order to help them understand rules regarding transgender athlete participation and learn how to better provide competent care to transgender athletes. There are over 1.4 million transgender adults in the United States. Transgender individuals undergo gender-affirming treatments including sex hormone therapy and gender-affirming surgery. An increasing number of transgender people are participating in sports and presenting to sports medicine clinics with injuries, yet there is little research about this athlete population. It is important that sports medicine providers understand the types of hormone treatments and surgeries and how these changes affect the musculoskeletal health of transgender people. Additionally, transgender people may require specific considerations when interacting with medical providers. Furthermore, sports medicine providers are often consulted to formulate transgender athlete inclusion policy. These policies are continuously changing, as new evidence becomes available, which may be difficult to understand without knowledge of the gender transition process.

This book explains the original meaning of the two religion clauses of the First Amendment: "Congress shall make no law [1] respecting an establishment of religion or [2] prohibiting the free exercise thereof." As the book shows, both clauses were intended to protect the free exercise of religion or religious freedom. West shows the position taken by early Americans on four issues: (1) the general meaning of the "free exercise of religion," including whether it is different from the meaning of "no establishment of religion"; (2) whether the free exercise of religion may be intentionally and directly limited, and if so, under what circumstances; (3) whether laws regulating temporal matters that also have a religious sanction violate the free exercise of religion; and (4) whether the free exercise of religion gives persons a right to be exempt from obeying valid civil laws that unintentionally and indirectly make it difficult or impossible to practice their religion in some way. A definitive work on the subject and a major contribution to the field of constitutional law and history, this volume is key to a better understanding of the ongoing constitutional adjudication based on the religion clauses of the First Amendment.

For more than fifty years Robert Morgan has brought to life the landscape, history and culture of the Southern Appalachia of his youth. In 30 acclaimed volumes, including poetry, short story collections, novels and nonfiction prose, he has celebrated an often marginalized region. His many honors include four NEA Fellowships, a Guggenheim Fellowship and an award from the American Academy of Arts and Letters, as well as television appearances (The Best American Poetry: New Stories from the South, Prize Stories: The O. Henry Awards). This first book on Morgan collects appreciations and analyses by some of his most dedicated readers, including fellow poets, authors, critics and scholars. An unpublished interview with him is included, along with an essay by him on the importance of sense of place, and a bibliography of publications by and about him.

The First Amendment of the U. S. Constitution begins: "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof . . . ." The Supreme Court has consistently held that these words, usually called the "religion clauses," were meant to prohibit laws that violate religious freedom or equality. In recent years, however, a growing number of constitutional law and history scholars have contended that the religion clauses were not intended to protect religious freedom, but to reserve the states' rights to legislate on. If the states' rights interpretation of the religion clauses were correct and came to be accepted by the Supreme Court, it could profoundly affect the way the Court decides church-state cases involving state laws. It would allow the states to legislate on religion-even to violate religious freedom, discriminate on the basis of religion, or to establish a particular religion. This book carefully, thoroughly, and critically examines all the arguments for such an interpretation and, more importantly, all the available historical evidence. It concludes that the clauses were meant to protect religious freedom and equality of the individuals not the states' rights

In the past, disease pattern mapping depended on census tracts based on political units, such as states and counties. However, with the advent of geographic information systems (GIS), researchers can now achieve a new level of precision and flexibility in geographic locating. This emerging technology allows the mapping of many different kinds of geographies, including disease rates in relation to pollution sources. Geocoding Health Data presents a state-of-the-art discussion on the current technical and administrative developments in geographic information science. In particular, it discusses how geocoded residential addresses can be used to examine the spatial patterns of cancer incidence, staging, survival, and mortality. The book begins with an introduction of various codes and their uses, including census geographic, health area, and street level codes. It goes on to describe the specific application of geocodes to cancer, detailing methods, materials, and technical issues. The text illustrates how to compile data maps for analysis and addresses issues, such as mismatch correction and data quality. It describes the current state of geocoding practices and discusses the use of individually geocoded cancer incidences in spatial epidemiology, distance estimation and spatial accessibilities, and tips for handling non-geocoded cases. Special consideration is given to privacy and confidentiality issues by focusing on disclosure limitation methods. With recent disease outbreaks and escalating concerns about bioterrorism, interest in the application of GIS to individual data is growing. The fundamental concepts presented by this book are of great value to anyone trying to understand the causes, prevention, and control of cancer as well as a variety of other diseases.

Building Team-based Working is designed for use by managers and consultants who are introducing team-based working into organizations. The book synthesizes knowledge about how to build team-based organizations, focusing particularly on the psychological and social processes that can facilitate or obstruct successful teamwork. Rather than advise managers on how to build effective teams, as most books in this area tend to do, this book instead focuses on how to build organizations structured around teams. The text is divided into six sections describing the six main stages of developing team-based working in an organization. The chapters follow a common structure. Each one opens with a summary of the aims and activities relevant to that stage and concludes with a selection of appropriate support materials and tools. These materials can also be downloaded from the CD accompanying the text. The advice given is based on evidence gathered by the authors over 20 years of practical management experience, research work in organizations, and consultancy across the public, manufacturing and service sectors.

volume XIX A of IAU Transactions contains the reports by Presidents of Commissions, covering the period July 1981 - June 1984. The topics of IAU Commissions deal with all of contemporary astronomy and the present volume therefore constitutes an exhaustive and unique record of astronomical research during this interval. It is particularly useful for astronomers and other scientists who want to gain an overview of a certain field, not necessarily near their own research area. Each Commission President was requested, by early 1984, to begin prep arations for the compilation of his/her Commission report. All members of Commissions were asked to supply details about their individual research pro grammes. The ensuing, very substantial task of concatenating was undertaken in late 1984 by the Presidents, often supported by a team of authors, all recog nized authorities in their fields. In order to preserve some measure of uni formity - which is in any case very difficult with so many authors - editorial guidelines were sent to Presidents, including the number of pages allotted to each Commission.

There is hardly any field of human endeavour which is more fundamental than the study of our surroundings. We have always wanted to learn what was behind our horizon, beyond the next mountain, on the other side of the ocean, on the next planet, at the end of the Universe. We have come a long way since our early ancestors gazed upon the sky in amazement. Giant optical and radio telescopes now allow us to "see" the early epochs of the Universe, revealing phenomena beyond our comprehension. Spacecrafts with on-board astronomical instrumentation circle the Earth and fly to the limits of the Solar System, providing invaluable new information about nearby and distant objects. Many people have the intuitive feeling that it is "easier and better" to study the Universe from above the Earth's atmosphere. However, this is only partially true in as much as electromagnetic radiation of certain wavelengths (e.g. X-rays) does not penetrate the atmosphere and can only be studied from balloons and space crafts * The advent of space-borne astronomy has not made ground-based observations obsolete - on the contrary, it is only thanks to the combination of the two that we have now a vastly more comprehensive picture of the Universe than just a few decades ago.
