Technology Differences over Space and Time looks at how countries use their productive resources—such as workers, skills, equipment and structures, and natural resources. Francesco Caselli develops methods to assess the efficiency with which productive inputs are used, and how these efficiencies vary across countries and over time. Caselli finds that richer countries use skilled workers relatively more efficiently than unskilled workers, and equipment and structures relatively more efficiently than natural resources. They also are relatively more efficient users of labor than of capital. Technological change tends to make countries particularly efficient at using skills and less efficient at using capital. Technical change also favors experienced workers. In order to interpret and understand these findings, Caselli presents a theory of technology choice. In this theory, firms pick technologies that make the most efficient use of the most abundant production factors when these factors are good substitutes for the less abundant factors. Firms pick technologies that make the most of less abundant factors when other suitable factors are not available for substitution. For example, rich countries, where skilled workers are abundant, use skilled workers efficiently, as these are good substitutes for unskilled workers. This flexible framework can be applied to other pairs of inputs, over time, and across countries. Technology Differences over Space and Time has significant implications not only for the theoretical understanding of development and technological innovation, but also for government formulation of industrial policy and multinationals making decisions about what to invest in and where to make those investments.

This paper compares technologies across space and time on the basis of factual and counterfactual substitution elasticities and argues that differences in estimated substitution elasticities should be decomposed into two counterfactual components. While the first component is designed to indicate how the ease of substitution is altered by varied economic circumstances, the second addresses the question of how technologies would compare under genuinely comparable situations. This argument is illustrated by the example of energy-price elasticities of capital before and after the oil crisis of the early 1970s.

Technological change is a powerful force in economic and social life. Technological change is both an endogenous and a disruptive process because inventors create new technologies by recombining existing technological ideas and because new technologies often drive older technologies and their associated capital and skills into obsolescence. Technological disruption resonates in the economies of cities, producing both local economic growth and decline, because city-regions are a scale at which many of the factors of production are coordinated. In the existing literature, there is broad agreement that knowledge builds on itself endogenously, and there is some recognition that innovation is disruptive with consequences for city-regions. Despite these acknowledgments, the sources of knowledge that inventors used to create historical inventions have not been systematically documented, the question of how new city-regions enter the process of endogenous knowledge production has not been resolved, the geographical distribution of breakthrough innovation has not been described nor explained, and the mechanisms through which inventors amass the technological knowledge needed to innovate in rapidly-evolving knowledge environments have not been adequately studied. In light of the above research gaps, this dissertation makes four contributions. First, it develops a method called knowledge phylogenetics and uses that method to create a long-run genealogy of technological knowledge containing over 8 million patented inventions created between 1836 and 2014. Second, it uncovers a general process that city-regions go through as they begin to become centers for innovation, involving the importation of non-local and disruptive ideas that are used to initiate local knowledge production. Third, it documents the extent to which breakthrough innovation is concentrated in large and knowledge-diverse cities, how that concentration changed over the 20th century, and how those changes resulted from asymmetric improvements in different types of communication technologies. Fourth, it calculates the productivity benefits that inventors receive from working in teams and from the experiences that they accumulate over time. In this regard, the dissertation shows that inventors do not benefit from the experience that they accumulate over time because inventors struggle to learn quickly enough to keep pace with the advances made in their knowledge fields.

LITHICS IN THE LAND OF THE LIGHTNING BROTHERS skilfully integrates a wide range of data-raw-material procurement, tool design, reduction and curation, patterns of distribution and association-to reveal the major outlines of Wardaman prehistory. At the same time, the book firmly situates data and methods in broad theoretical context. In its regional scope and thorough technological approach, this book exemplifies the best of recent lithic analysis and hunter-gatherer archaeology. Any archaeologist who confronts the challenge of classifying retouched stone tools should consult this volume for a clear demonstration of reduction intensity as a source of size and form variation independent of "type." Yet the demonstration is not merely methodological; Clarkson shows how the measurement of reduction intensity informs analysis of technological diversity and other cultural practices. In Clarkson's hands, Wardaman prehistory emerges as a particular record of the human past. Yet the book is also a case study in prolonged cultural response to environmental conditions and the way in which cultures persist and reproduce themselves over long spans of time. The result is an analytical tour de force that will guide hunter-gatherer archaeology in Australia and elsewhere for years to come.

Is it possible to travel in time and location like you can read in many books and see in some movies? What is (science) fiction and what is a possibility in the near future? This book explains the dimensions of time and location where it derives principles that should be obeyed. Clemens Willemsen PhD has written books on Biometrics & Identity as well as on Information Technology & Security. This book is less scientific but still worthwhile to read if you want to know more on this subject.

In the past decade there has been growing recognition that economic development is not mainly exogenously determined but, to a large extent, is a transformation process induced and governed by economic actors who respond to competitive, institutional and political challenge. This 'challenge and response' model is increasingly accepted as a valid analytical framework in modem growth theory and also explains the popularity of endogenous growth approaches to technological innovation issues. However, a major and as yet largely under-researched topic is the question of the diffusion and adoption of new technological changes in the context of space-time dynamics. This diffusion and adoption pattern has obviously clear spatial and temporal variations connected with behavioural responses which may vary over time and different locations. This means that a closer analysis of spatio-temporal opportunities and impediments is necessary in order to fully map the complex interactions of technology and economy in space and time. This volume sets out to bring together a collection of original contributions commissioned by the editors to highlight the spatio-temporal patterns and backgrounds of the diffusion and adoption of new technologies. Some are in the nature of a survey, others.have a modelling background and again others are case studies. The contributions originate from different countries and different disciplines. This book is complementary to a previously published volume on technological innovation, Technological Change, Economic Development and Space, edited by C.S. Bertuglia, M.M. Fischer and G. Preto, and also published by Springer-Verlag (1995).

ARIST, published annually since 1966, is a landmark publication within the information science community. It surveys the landscape of information science and technology, providing an analytical, authoritative, and accessible overview of recent trends and significant developments. The range of topics varies considerably, reflecting the dynamism of the discipline and the diversity of theoretical and applied perspectives. While ARIST continues to cover key topics associated with "classical" information science (e.g., bibliometrics, information retrieval), editor Blaise Cronin is selectively expanding its footprint in an effort to connect information science more tightly with cognate academic and professional communities.

Investigations in space have been conducted in both manned and unmanned space vehicles. Space: Technologies, Materials and Structures explains the development of hardware and instrumentation designed to operate in the severe conditions of space. For the operation and repair of such vehicles, engineers and scientists must consider a broad range of practical issues, such as the construction and mounting of extended large structures, discussed here using the Mir space station as a case study. Another consideration is the manufacture of permanent joins by welding and brazing, as well as the application of various coatings by thermal evaporation. Astrophysicists, engineers and applied mathematicians will benefit from this volume.
