    • The Low-Energy Undulator Test Line (LEUTL) at the Advanced Photon Source, Argonne National Laboratory, is intended to demonstrate the basic operation of a SASE-based free-electron laser. Goals include comparison of experimental results With theoretical predictions and scaling laws, identification of problems relevant to fourth-generation light source construction and operation and the means of addressing them, the development of operational and diagnostic techniques to optimize SASE FEL performance and increase repeatability from run to run. and performance of initial pioneering experiments capable of exploiting the unique properties of the laser. The basic layout and operational philosophy of the LEUTL experiment is presented. A summary of past results, including saturation, is reviewed, and a description of recent results is presented. We conclude with future plans, which include pressing to shorter wavelengths and incorporating user experiments into the LEUTL experimental program.

  • Towards a theory of indigenous entrepreneurship

    • Indigenous populations throughout the world suffer from chronic poverty, lower education levels, and poor health. The 'second wave' of indigenous development, after direct economic assistance from outside, lies in indigenous efforts to rebuild their 'nations' and improve their lot through entrepreneurial enterprise. This paper suggests that there is a distinguishable kind of activity appropriately called 'indigenous entrepreneurship'. We begin by defining the indigenous population and noting some general facts about their numbers and distribution. In an effort to discern the potential for development on indigenous peoples' own terms, we then explore three frameworks for understanding efforts at development, including indigenous development: modernisation theory, dependency theory and (at somewhat greater length) regulation theory. After distinguishing 'indigenous' from 'ethnic' entrepreneurship, we conclude by identifying a number of lead questions that present themselves at the outset of an enquiry into the nature of indigenous entrepreneurship.
