This edition of the Sonatinas, Op. 36 is based on the first printing, published by Clementi himself. In addition to Clementi's own articulations, fingerings and ornaments presented in dark print, additional performance suggestions by Dr. Palmer appear in light gray print. These guidelines were drawn from Clementi's companion work, Introduction to the Art of Playing on the Pianoforte, first published in 1801.

A group of resourceful kids start "solution-seekers.com," a website where "cybervisitors" can get answers to questions that trouble them. But when one questioner asks the true meaning of Christmas, the kids seek to unravel the mystery by journeying back through the prophecies of the Old Testament. What they find is a series of "S" words that reveal a "spectacular story!" With creative characters, humorous dialogue and great music, The "S" Files is a children's Christmas musical your kids will love performing.

This book presents a systematic overview of cutting-edge research in the field of parametric modeling of personal income and wealth distribution, which allows one to represent how income/wealth is distributed within a given population. The estimated parameters may be used to gain insights into the causes of the evolution of income/wealth distribution over time, or to interpret the differences between distributions across countries. Moreover, once a given parametric model has been fitted to a data set, one can straightforwardly compute inequality and poverty measures. Finally, estimated parameters may be used in empirical modeling of the impact of macroeconomic conditions on the evolution of personal income/wealth distribution. In reviewing the state of the art in the field, the authors provide a thorough discussion of parametric models belonging to the " -generalized" family, a new and fruitful set of statistical models for the size distribution of income and wealth that they have developed over several years of collaborative and multidisciplinary research. This book will be of interest to all who share the belief that problems of income and wealth distribution merit detailed conceptual and methodological attention.

This book examines how the US is dealing with the challenge of reconciling its global interests with regional dynamics and how it is able to produce and sustain order at the system level and within regional subsystems. The book comprises four parts, the first of which addresses global issues such as nonproliferation, trade, and freedom of the seas. US policies in these areas are carefully analyzed, considering whether and how they have been differently implemented at the regional level. The remaining parts of the book focus on the US posture toward specific regions: Europe, the Middle East, and East Asia. The policies adopted by the US to confront the most relevant challenges in each region are identified, and the ways in which policies in a specific region influence or are influenced by challenges in another region are explored. The book is a rich source of knowledge on the nature of the balance that the US has pursued between global and regional interests. It will be of much interest to scholars, to practitioners, to postgraduate/PhD students of international relations theory and American foreign policy, and to all with an interest in the ability of the US to produce international order.

This volume collects a number of the invited lectures and a few selected contrib utions presented at the International Symposium on Structure and Dynamics of Nucleic Acids, Proteins and Membranes held August 31st through September 5th, 1986, in Riva del Garda, Italy. The title of the conference as well as a number of the topics covered represent a continuation of two previous conferences, the first held in 1982 at the University of California in San Diego, and the second in 1984 in Rome at the Accademia dei Lincei. These two earlier conferences have been documented in Structure and Dynamics: Nucleic Acids and Proteins, edited by E. Clementi and R. H. Sarma, Adenine Press, New York, 1983, and Structure and Motion: Membranes, Nucleic Acids and Proteins, edited by E. Clementi, G. Corongiu, M. H. Sarma and R. H. Sarma, Adenine Press, New York, 1985. At this conference in Riva del Garda we were very hesitant to keep the name of the conference the same as the two previous ones. Indeed, a number of topics discussed in this conference were not included in the previous ones and even the emphasis of this gathering is only partly reflected in the conference title. An alternative title would have been Structure and Dynamics of Nucleic Acids, Proteins, and Higher Functions, or, possibly, "higher components" rather than "higher functions."

In a way the MOTECC-89 project started in the early sixties at the IBM Research Laboratory in San Jose, California. The six years of post-doctoral research, first with Giulio Natta on conductive polymers, with Michael Kasha on spin-orbit effects, with Kenneth S. Pitzer on high temperature molecules and thermo dynamics and with R. S. Mulliken in the quantum chemistry of small molecules had demonstrated pragmatically the importance of a broad-based research and also let me taste some of the excitement to be derived from interdisciplinarity. Thus when I started to gather a department in the newly opened IBM Research Laboratory in San Jose, California, I purposely named it "Large Scale Scientific Computation Department," avoiding reference to chemistry, physics, statistical mechanics or fluid dynamics, which were our main tasks. In the sixties interdisciplinarity was more and more recognized as a most important if not nec essary avenue to cope with the technical needs of our society. However, at that time interdisciplinarity was synonymous with "team work," and true interdisciplinarity was a formidably difficult objective. Although I headed an excellent group of scientists with different backgrounds and there was much progress and creativity, still each one of us was more or less conducting his own research in his own field with occasional cross-field partnerships and with some of the computational techniques as our common base. Later, in 1974, I made a second attempt, this time starting a new department at the Donegani Institute, Montedison, in Novara, Italy."

The acetylcholine nicotinic receptor is an ionic channel whose aperture is directly controlled by acetylcholine. It is a key molecule in the chemical communication between nerve cells and between nerve cell and muscle. The structure and function of muscular nicotinic receptors have been unraveled in recent years and its beauty and mysteries were reviewed in the Santorini NATO ARW organized by Dr. Maelicke in 1986. The neat, linear structure of this molecule and its conservation throughout evolution, from bacteria to humans, have led to the suggestion that it has reached the optimal structure for performing its function. But when scientists began to look at the nicotinic receptor in the nervous system, they found several surprises. From the beginning, pharmacological and physiological experiments, have made it clear that the functional characteristics of neuronal nicotinic receptors are substantially different from those of muscle receptors. Furthermore, recent sophisticated techniques such as patch clamp and gene cloning have revealed that the nicotinic receptor in the nervous system is not a single molecule but (although there are some important exceptions) a large family of similar molecules, which have in common the property of binding nicotinic agonists or antagonists. Over the last few years, the physiological implications of nicotinic receptors have been reevaluated on the basis of more precise behavioural and pharmacological techniques. Moreover, the involvement of nicotinic receptors in degenerative pathologies of the eNS, such as Parkinson's and Alzheimer's disease, has also been discovered very recently.

Any study on the historical evolution of nations and countries points out the decisive importance of productivity trends. We are all very familiar with the main evolution which started with a hunting society at the dawn of civilization, then moved to an agricultural society, and quickly to craftsmanship and com merce. The beginning of the industrial society dates back to the end of the eighteenth century in England, with the introduction of the assembly line in the textile and smelting industries. However, in the last few decades, we are becoming more and more acutely aware of the paramount importance of the production of "information." Indeed, according to a few economists today, we should be classified as living in an information society which has superseded the industrial society. At this point it simply becomes necessary to talk about the computer informa tion industry, which is more and more pervading our lives, from the personal computer, to the workstation, to information networks and electronic mail, to the blueprint executed by robots, to the supercomputer necessary in any major scientific and engineering task. The computer has already brought about a momentous change in the production line - less and less man-size, more and more robot-size. But this rush to tech nical innovation has not stopped at this point. Artificial intelligence and expert systems are becoming a more and more important factor for production by many enterprises and activities."

1. 1 STATEMENT OF THE PROBLEM Quantum chemistry judged not from the ever present possibility of unex pected developments but on the basis of the achievements in the last fifty years, is predominantly limited to attempts to solve for the energy and expectation values of wave functions representing, in the limit, an exact solution to the Schroedinger equation. Because of well-known dif ficulties in system with more than about 50 electrons, the adopted ap proximations are generally rather crude. As examples of quantum chemical approximations we mention the total or partial neglects of electron correlation, the neglect of relativistic effects, the use of subminimal basis sets, the still present neglect of inner-core electrons in semi-empirical methods, the acceptance of the Born-Oppenheimer approximations, and so on. In general, the larger the system, in terms of the number of electrons, the cruder the approxima tion. In a way, the present status of quantum chemistry might appear as nearly paradoxical. Indeed, for small systems, where very accurate ex periments are often available, and therefore, there is not a great need to obtain (from quantum chemistry) predictions of new data but rather, a theoretical interpretation of the existing data, we find increasi gly powerful and reliable quantum chemical methods and techniques."
