Evaluating Winnipegâs Unicity Government: Past Efforts and Present Challenges
Report: ii, pp.32; digital file.This study and those which follow in this series * continue the
Institute 1s tradition of monitoring and contributing to Unicity 1s
development, a tradition which was established by the "Future City"series of IUS publications. This report focuses on evaluation,
while those which follow focus on providing basic data and analysis
of Unicity 1S performance over the last ten years since those earlier
studies were published, as well as relating the Unicity experience
to contemporary intellectual and practical contexts.Canada Mortgage and Housing Corporatio

Impediments to agricultural growth in Zambia:
This paper has been prepared as part of the Zambia country study of the Macroeconomic and Regional Integration in Southern Africa (MERRISA) project and serves as a background paper for modeling exercises. The paper focuses on analyzing institutional constraints on the development of the agricultural sector in Zambia. It argues that by changing some of the rules and neglecting to integrate these changes into the complete institutional setting, policymakers have been unable to achieve their goals. Other constraints on Zambia's agricultural development are of a more technical nature. There are problems with Zambia's infrastructure. This paper argues that these are problems of the provision of public and merit goods mainly occurring in rural areas. Farmers emphasize their limited access to resources like credit, fertilizer, and draft animals. Although these problems could indicate market failures, it is the view of the authors that they are mainly due to transition uncertainties.Resource management., Infrastructure (Economics) Rural areas Zambia., Agricultural development., Agricultural resources.,

Material aspects for preparing HTS quasiparticle injection devices
Quasiparticle (QP) injection devices based on HTS could play an important role in future superconducting applications if material aspects can be better controlled. One reason why this kind of device received little attention in the past is the lack of an appropriate barrier for QP tunnelling. In a series of experiments, we used different barriers to test if they are suitable, i.e. if a current and possibly a voltage gain can be achieved. We improved the performance of planar YBCO/natural barrier/Au devices and a current gain of more than 6 at 40 K was observed. Most devices, however, showed signs of heating effects. Another barrier material was SrTiO3 with layers of 5-6 nm thickness. Current-voltage characteristics showed that the barriers were continuous and we observed current gains of up to 3 at 60 K. PrBa2 Cu3O7-x is an interesting candidate if one could overcome the problem of resonant inelastic tunnelling for QP. In a series of experiments we demonstrated that, even for 3 Mn thin PBCO barriers on a- and c-axis oriented YBa2Cu3O7-x, most devices showed at best a current gain of 1. However, we have indications that a current gain of 10 could be possible with unity voltage gai
