    Space development scenarios and the choice of technologies to carry them out depend upon the future social, economic, and political factors. A brief discussion concerning the impact of sociopolitical conditions on space exploration is presented. Some of the topics mentioned include: space weapons/warfare, international cooperation, NASA's Search for Extraterrestrial Intelligence (SETI) Program, and superpower rivelry

    These papers comprise a peer-review selection of presentations by authors from NASA, LPI industry, and academia at the Second Conference (April 1988) on Lunar Bases and Space Activities of the 21st Century, sponsored by the NASA Office of Exploration and the Lunar Planetary Institute. These papers go into more technical depth than did those published from the first NASA-sponsored symposium on the topic, held in 1984. Session topics covered by this volume include (1) design and operation of transportation systems to, in orbit around, and on the Moon, (2) lunar base site selection, (3) design, architecture, construction, and operation of lunar bases and human habitats, and (4) lunar-based scientific research and experimentation in astronomy, exobiology, and lunar geology

    Automatic Compilation from High-Level Biologically-Oriented Programming Language to Genetic Regulatory Networks

    Background The field of synthetic biology promises to revolutionize our ability to engineer biological systems, providing important benefits for a variety of applications. Recent advances in DNA synthesis and automated DNA assembly technologies suggest that it is now possible to construct synthetic systems of significant complexity. However, while a variety of novel genetic devices and small engineered gene networks have been successfully demonstrated, the regulatory complexity of synthetic systems that have been reported recently has somewhat plateaued due to a variety of factors, including the complexity of biology itself and the lag in our ability to design and optimize sophisticated biological circuitry. Methodology/Principal Findings To address the gap between DNA synthesis and circuit design capabilities, we present a platform that enables synthetic biologists to express desired behavior using a convenient high-level biologically-oriented programming language, Proto. The high level specification is compiled, using a regulatory motif based mechanism, to a gene network, optimized, and then converted to a computational simulation for numerical verification. Through several example programs we illustrate the automated process of biological system design with our platform, and show that our compiler optimizations can yield significant reductions in the number of genes () and latency of the optimized engineered gene networks. Conclusions/Significance Our platform provides a convenient and accessible tool for the automated design of sophisticated synthetic biological systems, bridging an important gap between DNA synthesis and circuit design capabilities. Our platform is user-friendly and features biologically relevant compiler optimizations, providing an important foundation for the development of sophisticated biological systems.National Institutes of Health (U.S.) (Grant # 7R01GM74712-5)United States.

    Prisoners’ Families’ Research: Developments, Debates and Directions

    Get PDF
    After many years of relative obscurity, research on prisoners’ families has gained significant momentum. It has expanded from case-oriented descriptive analyses of family experiences to longitudinal studies of child and family development and even macro analyses of the effects on communities in societies of mass incarceration. Now the field engages multi-disciplinary and international interest although it arguably still remains on the periphery of mainstream criminological, psychological and sociological research agendas. This chapter discusses developments in prisoners’ families’ research and its positioning in academia and practice. It does not aim to provide an all-encompassing review of the literature rather it will offer some reflections on how and why the field has developed as it has and on its future directions. The chapter is divided into three parts. The first discusses reasons for the historically small body of research on prisoners’ families and for the growth in research interest over the past two decades. The second analyses patterns and shifts in the focus of research studies and considers how the field has been shaped by intersecting disciplinary interests of psychology, sociology, criminology and socio-legal studies. The final part reflects on substantive and ethical issues that are likely to shape the direction of prisoners’ families’ research in the future

    Big-Men and Business: Entrepreneurship and Economic Growth in the New Guinea Highlands

    No full text
    Humanities Open Book Program, a joint initiative of the National Endowment for the Humanities and the Andrew W. Mellon FoundationHigh in the New Guinea mountains a sociological drama of unique design has been unfolding since the early 1930s. At that time the first of the Europeans who would take part in the area's development trekked into the remote highlands. These early gold prospectors, patrol officers, and missionaries made the first outside contacts with the Stone Age Gorokan people. These encounters ultimately catapulted the Gorokans, subsistence gardeners cultivating sweet potatoes and raising pigs, squarely into the twentieth century. The magnitude of the economic and social changes that followed in the next forty years clearly distinguish the Gorokan case as one of the most remarkable examples of human adaptability to be witnessed in modern times. Although popular thinking has it that traditional societies are change-resistant and that social reforms therefore must precede economic and other types of development, the Gorokans, remarkably, reversed the process and passed from the Stone Age to the twentieth-century marketplace in one generation. Today they are heavily involved in growing coffee, they have developed their own trucking industry for transporting coffee and other cash crops to market, and they are venturing into the raising of beef cattle and the operation of trade stores and various businesses. Big-Men and Business is the record of this extraordinary case of economic change, based on field study conducted in 1967 and 1968. Dr. Finney interviewed many of the Gorokan leaders of this commercial revolution, and draws comparisons between the Gorokan experience and that of other New Guinean peoples. One of the results of his research indicates that the Gorokans may have been predisposed to entrepreneurship. Traditionally, a Gorokan "big-man" was the man who acquired the valuables of his society—cowrie shells, mother-of-pearl shells, pigs, and bird-of-paradise plumes. These leaders were honored for their skills in the flourishing local exchange system. This fact, coupled with a supportive colonial relationship and a favorable natural environment, enhanced the Gorokans' adaptation, and thus the leap from the world of traditional exchange to one where business is conducted on a cash basis was, in reality, a short step.
