A penetrating exploration of affirmative action's continued place in 21st-century higher education, The Next Twenty-five Years assembles the viewpoints of some of the most influential scholars, educators, university leaders, and public officials. Its comparative essays range the political spectrum and debates in two nations to survey the legal, political, social, economic, and moral dimensions of affirmative action and its role in helping higher education contribute to a just, equitable, and vital society. David L. Featherman is Professor of Sociology and Psychology and Founding Director of the Center for Advancing Research and Solutions for Society at the University of Michigan. Martin Hall is Vice-Chancellor of the University of Salford, Greater Manchester, and previously was Deputy Vice- Chancellor at the University of Cape Town. Marvin Krislov is President of Oberlin College and previously was Vice President and General Counsel at the University of Michigan.

This volume is the product of a conference on the theme 'Development - the Next Twenty-five Years' which the Institute of Social Studies held in Decem ber 1977 to mark its own twenty-fifth anniversaryas a centre of development studies. We felt it appropriate at that point in time to caU together specialists from all over the world in an attempt to assess the 'state of play' in our field as we move into the last quarter of the twentieth century. 1 For several days, therefore, the Institute's new building house d a remarkable concentration of knowledge and experience concerning the problems of the so-calle d less developed countries, drawn from all over the world. Although it was inevitable that the participants should represent the past (and it was several times re marked that, in that sense, there were too few women present), the earnest and sometimes heated discussions looked to the future as much as to what had happened in the last twenty-five years. As the discussions proceeded, three things became apparent. Firstly , although the papers submitted did not fully reveal it, the ongoing debate between radicals and moderates, those who saw possibilities of change only basically through a direct break with existing structures and those who felt change possibIe within them, is by no means at an end.

Per Martin-Löf's work on the development of constructive type theory has been of huge significance in the fields of logic and the foundations of mathematics. It is also of broader philosophical significance, and has important applications in areas such as computing science and linguistics. This volume draws together contributions from researchers whose work builds on the theory developed by Martin-Löf over the last twenty-five years. As well as celebrating the anniversary of the birth of the subject it covers many of the diverse fields which are now influenced by type theory. It is an invaluable record of areas of current activity, but also contains contributions from N. G. de Bruijn and William Tait, both important figures in the early development of the subject. Also published for the first time is one of Per Martin-Löf's earliest papers.

Twenty-Five Years in the Black Belt provides a fascinating portrait of the conditions of black people and the state of race relations in Alabama at the turn of the twentieth century, and of author William J. Edwards' determination to uplift his race through eductation in the years following Reconstruction.

Interstellar carbon monoxide (CO) was first detected in 1970 with the 36 foot diameter telescope of the National Radio Astronomy Observatory! on Kitt Peak in Southern Arizona. R. W. Wilson, K. B. Jefferts, and A. A. Penzias of Bell Labs reported, "We have found intense 2.6 mm line radiation 2 from nine Galactic sources which we attribute to carbon monoxide." Soon afterward, several other basic molecules were also observed in space. IAU Symposium 170, CO: Twenty Five Years of Millimeter Wave Spectroscopy, was organized to commemorate those discoveries. The Symposium reviewed the accomplishments of a quarter century of research on interstellar molec ular gas, surveyed the current state of millimeter-wave spectroscopy, and gave a glimpse of what the next 25 years might hold. Studies of interstellar CO have revolutionized our understanding of the phases and dynamics of the interstellar medium, the initial and final stages of stellar evolution, the chemistry of dense and diffuse interstellar matter and of the solar system, the structure of the Milky Way galaxy, and the content and structure of other galaxies, some very distant. Spectroscopic studies of CO and other molecules are primary tools for investigating all these topics, which are among the most fundamental and active research areas in astrophysics. New developments in instrumentation, including sev eral powerful new telescopes, continue to keep millimeter and submillimeter wavelength radio astronomy at the forefront of research.

Twenty-Five Years of GOP Presidential Nominations examines the recent presidential nominees of the Republican Party. The author explores the idea that the presidential defeats of Republican nominees begin with the primary election choice of a moderate candidate in hopes that the chosen candidate's conservative rhetoric will translate into a general election victory. Written in a unique and dynamic style, this book details the recent history of the party's successes and failures through notable figures such as George H.W. Bush and Bob Dole.
