OBJECTIVE: Register, classify and assess the degree of technological obsolescence of medical imaging equipment in all health centers (publics and privates) in the Autonomous Communities of Valencia; also analyze the adoption, dissemination and identify the stages of technological equipment. DESIGN: Observational, cross-sectional retrospective. SUBJECT OF STUDY: The medical imaging equipment: Co...

A realistic assessment of future interconnect performance is addressed, specifically, by modeling copper (Cu) wire effective resistivity in the light of technological and reliability constraints. The scaling-induced rise in resistance in the future may be significantly exacerbated due to an increase in Cu resistivity itself, through both electron surface scattering and diffusion barrier effect....

The use of geothermal energy and its associated technologies has been increasing worldwide. However, there has been little paradigmatic research conducted in this area. This paper proposes a systematic methodology to research the development trends for the sustainable development of geothermal energy. A novel data analysis system was created to research the geothermal energy utilization trends,...

Purpose – The purpose of this paper is to study how causal ambiguity around technological competencies can help firms to achieve superior performance. Design/methodology/approach – Traditionally, it has been recognised that causal ambiguity of technology represents an effective protection against imitation. Recently, however, researchers have unearthed evidence that the effects of causal ambigu...

THE CRITICAL role played by new technology – its adaptation and diffusion – in the growth process of a developing economy is now widely accepted. The importance accorded to technological progress is of course not limited to LDCs only. Modern growth theory stresses that it is the technological application of labour and capital and not merely their presence which crucially influences the rate of ...

In this paper we present an algorithm that deals with trade interactions within a multi-region model. In contrast to traditional approaches this algorithm is able to handle spillover externalities. Technological spillovers are expected to foster the diffusion of new technologies, which helps to lower the cost of climate change mitigation. We focus on technological spillovers which are due to ca...

This paper deals with the aggregate effects of small, exogenous but idiosyncratic technological shocks on locally interacting firms. Its main purpose is to model a situation in which technological paradigms emerge through endogenous propagation and diffusion of information leading to an aggregate pattern. We develop a theoretical framework in which large technological correlations emerge due to...

Environmental issues constitute a significant driver of innovation in business companies. The paper starts from the historical perspective by identifying which have been the factors and significant steps in technological innovation that have been related to increasing environmental awareness in recent history. Then we analyse the dimensions of technological innovation as related to environmenta...

Technological innovation in the telecommunications sector is a key contributor to the rapid diffusion of e-business. The steady drive towards semiconductor miniaturisation leads to a continuous decline in the price of telecommunications equipment and increase in performance. Technological change therefore continues to transform the way telecommunications services are provided and used. Telecomm...

The three most extensively cited papers by Zvi Griliches deal with the diffusion of innovations, distributed lags and the sources of the growth of measured total factor productivity, respectively. The close economic connections between these dynamic phenomena remained largely unexplored and were at best only implicit in his published writings until late in his career. Yet, from his later reflec...
