FIRI - a Far-Infrared Interferometer

Half of the energy ever emitted by stars and accreting objects comes to us in the FIR waveband and has yet to be properly explored. We propose a powerful Far-InfraRed Interferometer mission, FIRI, to carry out high-resolution imaging spectroscopy in the FIR. This key observational capability is essential to reveal how gas and dust evolve into stars and planets, how the first luminous objects in the Universe ignited, how galaxies formed, and when super-massive black holes grew. FIRI will disentangle the cosmic histories of star formation and accretion onto black holes and will trace the assembly and evolution of quiescent galaxies like our Milky Way. Perhaps most importantly, FIRI will observe all stages of planetary system formation and recognise Earth-like planets that may harbour life, via its ability to image the dust structures in planetary systems. It will thus address directly questions fundamental to our understanding of how the Universe has developed and evolved - the very questions posed by ESA's Cosmic Vision.Comment: Proposal developed by a large team of astronomers from Europe, USA and Canada and submitted to the European Space Agency as part of "Cosmic Vision 2015-2025

LOCAL INDUSTRIAL DEVELOPMENT GROUPS: PERSPECTIVES AND PROFILES

Local industrial development groups (LIDGs) are often among the most visible organizations involved in community economic development. LIDGs annually spend billions of dollars directly or indirectly in various promotional and community improvement efforts. Yet relatively little is known about their organizational forms, their operating strategies, or their real impact on the economic development of communities. The study reported here was undertaken by researchers from three academic backgrounds in order to capture a rich, comprehensive view of this organizational type. In this paper, we discuss the research perspectives which informed our overall approach to the study, and subsequently, we present and discuss a preliminary profile of LIDGs, based on our recent national survey.
