  • Internal Migration

    A Comparative Perspective
    • 1st Edition
    • Alan A. Brown + 1 more
    • English
    Internal Migration: A Comparative Perspective is the third in a series of publications sponsored by the Committee on Comparative Urban Economics. This book highlights the integral migration in several regions of the world and the problems in regions of varying levels of economic development, and with different economic systems. This text is organized into five parts encompassing 24 chapters. The introductory part describes the interactions between migration and socioeconomic development, along with the functions and dynamics of the migration process. The next part explores the methodological aspects of migration, including the models, measurements, and theoretical reflections of internal migration. Other parts discuss the effect of migration on regions and individuals. These chapters also present some case studies of internal migration in the West and Eastern Europe. The demographic effect of migration on an urban population, the ethnicity as a barrier to migration, and the influence of social and geographical mobility on the stability of kinship systems are reviewed. The concluding part relates a comparative disciplinary and systemic view of migration. This book will be of great value to economists, sociologists, and social workers.

    • English
    Perspectives in Computing: Human and Machine Vision II compiles papers presented at the second Workshop on Human and Machine Vision held in Montreal, Canada on August 1-3, 1984. This book discusses the perception of transparency in man and machine, human image understanding, and connectionist models and parallelism in high level vision. The theory of the perceived spatial layout of scenes, generative systems of analyzers, and codon constraints on closed 2D shapes are also elaborated. This text likewise covers the environment- and viewer-centered perception of surface orientation, autonomous scene description with range imagery, and pre-attentive processing in vision. This publication is recommended for students and researchers interested in both fields of visual perception and computer vision.

    • Ryuzo Sato + 1 more
    • English
    Developments in Japanese Economics provides information pertinent to the fundamental aspects of the developments in Japanese economics. This book presents the process innovative aspect of Japanese science and technology. Organized into three parts encompassing 12 chapters, this book begins with an overview of the heterogeneous capital goods model that is stable even with an infinitely short forecast. This text then emphasizes that the changes in capital accumulation are relevant for economic growth and decline. Other chapters consider the examples of how Japanese economists apply theory to empirical endeavors. This book discusses as well the durable capital stock of the Japanese manufacturing industries. The final chapter attempts to investigate the validity of the theory of self-dual demand functions, which can be integrated into consumer's utility function, by using both Japanese and U.S. data. This book is a valuable resource for economists, sociologists, political scientists, financial historians, statisticians, and research workers.

    Nonnegative Matrices in the Mathematical Sciences provides information pertinent to the fundamental aspects of the theory of nonnegative matrices. This book describes selected applications of the theory to numerical analysis, probability, economics, and operations research. Organized into 10 chapters, this book begins with an overview of the properties of nonnegative matrices. This text then examines the inverse-positive matrices. Other chapters consider the basic approaches to the study of nonnegative matrices, namely, geometrical and combinatorial.

  • Transformations

    Mathematical Approaches to Culture Change
    • 1st Edition
    • Colin Renfrew + 1 more
    • English
    Transformations: Mathematical Approaches to Culture Change focuses on the application of contemporary mathematical techniques to the study of culture change and formulates problems in archaeology, anthropology, and historiography in such a way that they are susceptible to treatment of a mathematical kind. Mathematical models, extending from the almost purely quantitative methods of physics to the purely verbal conceptual explanations, are described. Emphasis is placed on catastrophe theoretic models that exemplify the use of soft mathematics in situations in which the use of hard quantitative models is not possible. Comprised of 21 chapters, this book begins with an overview of the role of mathematics in theoretical archaeology, followed by a discussion on two general categories of mathematical methods that seem to be suitable for modeling cultural transformations: methods of dynamical systems theory and methods that give greater emphasis on discrete entities and the structural relations or patterns among them. Subsequent chapters deal with the use of mathematics in history; morphogenesis in biological and social systems; simulation of the growth of hierarchies; and logistic trends in Southwest population growth. A reconstruction of political units in the Valley of Mexico during the Toltec period is also presented. This monograph will be of interest to archaeologists, anthropologists, historians, biologists, sociologists, and mathematicians.
