The ‘nanotechnology’ concept first captured the world’s attention when the Nobel Prize winner Richard Feynman advocated the possibility of widespread nanotechnology research by delivering his famous speech, “There’s Plenty of Room at the Bottom” just half a century ago. The emerging nanotechnology field comprises one of the fastestgrowing research and development (R&D) areas in the world (Natio...

Scientific motivation for equipping the GBT with receivers for the 3mm band (68-116 GHz) has been discussed in several memos [1]-[3], and later presented in a proposal by the GBT 3mm Receiver Working Group [4]. It was decided that the first receiver module to be built should be capable of both continuum detection and spectroscopy in the 68-92 GHz band (Module 1). Other frequencies and capabilit...

Economies are systems in which the macroscopically observable quantities emerge from the effects of interactions amongst the individual constituents of the system. They exhibit key features of complex systems: short-term non-predictability, emergent properties and multiple possible histories. The conventional approach to the control of the economy at the aggregate level requires the ability to ...

This paper attempts to answer two questions. Why did state governments begin to regulate the food and drug industry in late 19 century America? And why did the federal government become the ultimate regulator of the food and drug industry in the early 20 century? I argue that state government regulation emerged as a response to high transaction costs (specifically information costs) in the mark...

in modern times, trust has become an issue crucial to human societies and it has basic role in confronting policies with social problems, particularly in the field of environmental risks. to counter environmental risks such as climate change requires knowledge that is gained through trust to its related informational institutions. these institutions cause the awareness of environmental issues a...

rural sustainable development is one the most important components of achievement to sustainable development in a national scale which is not doable without using an efficient management. therefore, recognizing the problems ahead of local management in the scale of various geographical regions of the country and attempting to solve them by using proper course of actions could be instrumental. i...

m any middle-east countries, like iran, have dynamic banking industries and have observed merger and acquisitions (m&a) waves. m&a waves are usually defined in the developed world context and some of their main drivers were identified as: market timing, environment's shocks, merger manias, government regulation and regulatory, and technological changes. it has been discussed that merge...

Utilizing the Technology-Organization-Environment (TOE) theory and the literature on citizen engagement (or participation), we formulated a multiple-mediation model, examining (1) the contextual antecedents of e-participation and e-government development; and (2) the mediating role of e-participation (in form of e-information sharing, e-consultation, and e-decision-making) on the relationships ...
