This volume contains contributions based on the lectures delivered at the Fifth International Symposium on Quantum Optics. This Conference, the fifth in a tri ennial series hosted in New Zealand, was held in Rotorua, 13-17 February 1989. The Conference was attended by 75 participants from New Zealand, Australia, Japan, USA, France, Italy and Germany. There was also a high level of par ticipation from graduate students from New Zealand and Australia, who greatly benefitted from the opportunity to attend world-class conferences. The partici pants were housed in the Hyatt Hotel and surrounding motels and all enjoyed the relaxed atmosphere offered by Rotorua in the Southern Hemisphere summer. There were 24 invited papers, given as oral presentations of 40 minutes, and 22 poster papers. The major topics covered at the Conference were new experimental and theoretical results in nonclassical light, including sub-shot-noise light sources. We were fortunate in that all major experimental groups in the world working in this area were represented. The latest experimental results from AT & T Lab oratories, NT & T Laboratories, mM Laboratories, Ecole Normale Superieure and the Californian Institute of Technology were reported. New theoretical results from Southern Hemisphere participants included a true phase operator for quantum fields derived by Professor David Pegg of Griffiths University and a general treat ment of lasers pumped without shot noise by Professor D. F. Walls of Auckland University.

This volume contains notes based on the lectures delivered at the fourth New Zealand Symposium in Laser Physics, held at the University of Waikato, Hamilton, February 10-15, 1986. At this meeting, about 80 physicists work ing in many parts of the world met to discuss topics of current interest in contemporary laser physics and quantum optics. These symposia, which have been held triennially since 1977, have evolved into an important meet ing ground for experimentalists and theoreticians working in a very rapidly developing field. As the format has evolved, the number of participants, in cluding the number from overseas, has grown steadily, and this year a poster session was included for the first time, enabling a far greater range of topics to be discussed than was possible in the limited lecture time available. At this meeting the major interest of the participants concerned the the oretical investigation of squeezed states of the radiation field and the very recently reported experimental observations of such states. Other related ar eas of work reported here include bistability and chaotic behaviour of optical systems, the quantum theory of measurements, optical tests of general rel ativity, and the current technological limitations governing the stabilization of lasers. The editors would like to thank the participants for providing detailed notes for publication shortly after the meeting, and the various organisa tions that have provided financial support."

What do we know about literature circles now that we didn't understand eight or ten years ago? What new resources and procedures can help teachers organize their classroom book clubs better? What are the most common pitfalls in implementing student-led discussion groups? And getting beyond the basics, what do mature or "advanced" literature circles look like?

In this thoroughly revised and expanded guide, you will find new strategies, structures, tools, and stories that show you how to launch and manage literature circles effectively. Advanced variations are explored and include alternatives to role sheets and flexible new guidelines for their use.

The second edition includes:

• four different models for preparing students for literature circles using response logs, sticky notes, and newly designed role sheets;
• dozens of variations on the basic version of student-led bookclubs;
• new models and procedures for primary, intermediate, and high school grades;
• new materials for assessing and grading literature circles;
• an inventory of common management problems and solutions;
• new scheduling patterns for group meetings and reading time;
• ideas for using literature circles with nonfiction texts across the curriculum;
• research on literature circles, including correlation with increased achievement on standardized tests;
• an explanation of how literature circles match with the national standards for literacy education.

With detailed examples provided by twenty practicing teachers, Harvey Daniels offers practical and concrete suggestions for each aspect of book club management and proven solutions for problems that arise.

Social Security Disability Insurance (SSDI) program provides benefits to insured workers with disabilities under the full retirement age and their dependants based on an individual worker's earnings and work history in covered employment. Recently, some Members of Congress and the public have expressed concern over the financial sustainability of the SSDI program. This book provides an overview of reform proposals designed to mitigate the growth in SSDI rolls. Most of the proposals discussed in this book focus on reducing the inflow (incidence) of new beneficiaries into the program. The authors also focus on information on two components of federal disability benefits, those provided through the Social Security Disability Insurance (SSDI) and the Supplemental Security Income (SSI) programs, policy options for the social security disability insurance program and provide a testimony of David C Stapleton on securing the future of the social security disability program.

This practical manual presents an innovative modular treatment for adults and adolescents with a wide range of sleep and circadian rhythm problems, such as insomnia, daytime sleepiness, poor sleep quality, and irregular sleep-wake schedules. The treatment applies broadly to all individuals with sleep problems, including those with psychiatric disorders. It is grounded in a cutting-edge understanding of sleep health and integrates elements of cognitive-behavioral therapy for insomnia (CBT-I), interpersonal and social rhythm therapy (IPSRT), and other evidence-based therapies. Each module is described in detail, including specific practitioner guidance, sample scripts, developmental adaptations, and tips for enhancing motivation.
