Esprit 90

The 1990 ESPRIT Conferene is being held in Brussels from the 12th November to the 15th November. Well over 1700 participants from all over Europe and overseas are expected to attend the various events. The Conference will offer the opportunity to be updated on the results ofthe ESPRITprojects and Basic Research actions andto develop international contacts with colleagues, both within a specific branch of Information Technology and across different branches. The first three days of the Conference are devoted to presentations of Esprit projects and Basic Research actions structured into plenary and parallel sessions; the scope of the Conference has been broadened this year by the inclusion of several well-known international speakers. All areas of Esprit work are covered: Microelectronics, Information Processing Systems, Office and Business Systems, Computer Integrated Manufacturing, Basic Research and aspects of the Information Exchange System. During the IT Forum on Thursday November 15th, major European industrial and political decision-makers will address the audience in the morning. In the afternoon, a Round Table will discuss the impact of Information Technology on society. More than 100 projects and actions will display their major innovations and achieve ments at the Esprit Exhibition which will be, for the first time, open to the general public.

Time series with mixed spectra are characterized by hidden periodic components buried in random noise. Despite strong interest in the statistical and signal processing communities, no book offers a comprehensive and up-to-date treatment of the subject. Filling this void, Time Series with Mixed Spectra focuses on the methods and theory for the statistical analysis of time series with mixed spectra. It presents detailed theoretical and empirical analyses of important methods and algorithms. Using both simulated and real-world data to illustrate the analyses, the book discusses periodogram analysis, autoregression, maximum likelihood, and covariance analysis. It considers real- and complex-valued time series, with and without the Gaussian assumption. The author also includes the most recent results on the Laplace and quantile periodograms as extensions of the traditional periodogram. Complete in breadth and depth, this book explains how to perform the spectral analysis of time series data to detect and estimate the hidden periodicities represented by the sinusoidal functions. The book not only extends results from the existing literature but also contains original material, including the asymptotic theory for closely spaced frequencies and the proof of asymptotic normality of the nonlinear least-absolute-deviations frequency estimator.

Gans ranks at the head of that important group of Hegelian thinkers that bridged the generations of Hegel and Marx. ! Yet there is a large gap between Gans 's historical importance and the scholarship on him. Despite a renewal of interest in Gans's work on the Continent,2 Gans remains almost completely unknown to English-Ianguage scholars, and almost none ofhis work has been 3 previously translated. His Prefaces to his posthumous editions of Hegel's writings are inaccessib1e to English speakers, despite the fact that they shed important light on the authenticity of the so-called Additions to those texts. His Preface to Hegel's Philosophy ofLaw has never been translated before, while his Preface to the Philosophy of History has been omitted from reprintings 4 for generations. Moreover, the recent scholarship on the Continent has focused on Gans 's political and philosophical rather than his legal writings. There is little dis cussion in any language ofhis system oflaw, which is the focus ofthe present study. Some of the reasons for the neglect of Gans are obvious. Gans cannot be a hero for most readers today. He accepted apostasy as a means to profes sional advancement. And though more liberal than Hegel, Gans nonetheless accommodated himself to the results of the Restoration and evaded political persecution that might have kindled the sympathy of later generations.

This study offers an overall interpretation of Hume's Treatise of Human Nature. I have emphasized throughout the dialectic between associationism and a theory of critical judgment - the "combat" of Book I -which con tinues in Books II and III and with no apparent winner. A theory of critical judgment is fIrst worked out in Book I under what Hume calls "general rules." The theory explains how unreasonable judgments may be made reasonable and is made use of again in Book III to correct partial evalua tions. Two sorts of general rules compete for prescriptive claims and two sides of human nature, the untutored and the more cultivated and reflective, contribute to science and morality. of David Hume by Annette Baier I was fIrst introduced to the philosophy when she conducted a seminar on the Treatise at the Graduate Center of The City University of New York. Much of the enthusiasm I have sustained for Hume has been due to the teachings of Professor Baier and to the conversations I have had with her. I have profIted from the encouragement and suggestions of Nicholas Capaldi just prior to beginning the work. Charles Landesman, Martin Tamny, and Stephan Baumrin read earlier versions of the manuscript and offered many constructive criticisms. Joram Haber was readily available to hear out my ideas. I am grateful to my wife, Marianne, and children, Anna and Aaron, for their patience and support throughout the project.
