Large time behaviour of solutions of a system of generalized Burgers equation
In this paper we study the asymptotic behaviour of solutions of a system of
partial differential equations. When the equation reduces to the
Burgers equation and was studied by Hopf. We consider both the inviscid and
viscous case and show a new feature in the asymptotic behaviour.Comment: 9 page
Unintended Consequences of Transnational Activism: Case Studies from the Brazilian Amazon
Transnational advocacy networks play a major role in internationalizing local grassroots movements through connections with international activists, foreign governments, and other powerful actors. However, in some cases, unequal power dynamics between members of networks produces less than optimal outcomes for local groups. This study compares two cases of grassroots movements in the Brazilian Amazon that became part of larger transnational advocacy networks to examine why some groups benefit from participation while others do not. The results suggest that groups with greater resources and stronger organizational capacities prior to contact with outside activists tend to benefit while those with few resources and weak organizational capacities do not experience the same benefits. These findings have important ramifications for the notion of mutually empowering relationships among network members and the effectiveness of transnational movements at serving local interests
Hypnosis: A Medico-Moral Evolution
Author\u27s Introductory Note: About two years ago at the request of His Eminence, the late Samuel Cardinal Stritch, Archbishop of Chicago, we started an investigation into the subject of hypnosis with the intention of making a medico-moral evaluation. To faciliate our work we drew up a questionnaire and sent it to six leading Catholic psychiatrists: Father William J. Devlin, S.J. of Loyola University, Chicago, Ill., Doctors Francis J. Braceland of the Institute of Living, Hartford, Conn., Francis J. Gerty of the University of Illinois, Chicago, Ill., John J. Madden of Loyola University Chicago, Ill., John J. Nurnberger of the University of Indiana, Indianapolis, Ind., and to Edward A. Strecker of the University of Pennsylvania, Philadelphia, Penn. These men mediately or immediately directed us to send the questionnaire also to the following doctors who have been using hypnosis in their clinical practice: Doctors Milton H. Erickson, President of the American Society of Clinical Hypnosis, of Phoenix, Ariz.; Merton M. Gill of Berkeley, Cal.; William S. Kroger of Chicago, Ill.; Lawrence S. Kubie of New York, N.Y.; Harold Rosen, Executive Secretary of the Society for Clinica1 and Experimental Hypnosis, of Johns Hopkins University, Baltimore, Md and Lewis R. Wolberg of New York, N.Y. We also sent the questionnaire to Mr. Stanley L. Morel. a hypnotist studying in Chicago, Ill. Since all thirteen of these men answered the questionnaire in more or less detail, our debt of gratitude to them is very great. Some sent impartant articles and references to help in the study. In the body of the article where we quote these men without any specific reference we are quoting from their private answers to the questionnaire. Two other sources that we found especially helpful are the two official reports on hypnosis made by the British Medical Association. published in the British Medical journal. April 23, 1955, and by the American Medical Association, published in the Journal of the American Medical Association, Sept. 13, 1958
JIDT: An information-theoretic toolkit for studying the dynamics of complex systems
Complex systems are increasingly being viewed as distributed information
processing systems, particularly in the domains of computational neuroscience,
bioinformatics and Artificial Life. This trend has resulted in a strong uptake
in the use of (Shannon) information-theoretic measures to analyse the dynamics
of complex systems in these fields. We introduce the Java Information Dynamics
Toolkit (JIDT): a Google code project which provides a standalone, (GNU GPL v3
licensed) open-source code implementation for empirical estimation of
information-theoretic measures from time-series data. While the toolkit
provides classic information-theoretic measures (e.g. entropy, mutual
information, conditional mutual information), it ultimately focusses on
implementing higher-level measures for information dynamics. That is, JIDT
focusses on quantifying information storage, transfer and modification, and the
dynamics of these operations in space and time. For this purpose, it includes
implementations of the transfer entropy and active information storage, their
multivariate extensions and local or pointwise variants. JIDT provides
implementations for both discrete and continuous-valued data for each measure,
including various types of estimator for continuous data (e.g. Gaussian,
box-kernel and Kraskov-Stoegbauer-Grassberger) which can be swapped at run-time
due to Java's object-oriented polymorphism. Furthermore, while written in Java,
the toolkit can be used directly in MATLAB, GNU Octave, Python and other
environments. We present the principles behind the code design, and provide
several examples to guide users.Comment: 37 pages, 4 figure
