Building on an international literature that stresses the growing importance of cities in both the economy and governance, this paper proceeds from the premise that national government support is essential to the maintenance of a social safety net, but that a great deal of local initiative is also necessary in order to ensure that national government funds are spent in a manner appropriate to the very different conditions in different cities. The paper focuses on a case in which a municipal government initiated a tri-level government program. Winnipeg officials and politicians developed a proposal for federal and provincial participation in a locally created welfare-to-work scheme, a scheme that, unlike conventional workfare, offered union wages and training leading to well-paid work. The municipal government provided on-the-job training for workers selected from the welfare rolls to carry out infrastructure upgrades and financed the project with money the federal and provincial governments saved on welfare payments. The paper argues that the municipal government was uniquely well placed to identify needed work, as well as to choose welfare recipients who would be able to benefit from the job training on offer. In this case, therefore, we argue that local initiative was essential to the success of this federally and provincially financed welfare-to-work program. The findings of the theoretical literature we review suggest that it could eventually become a precedent for further municipal and local activism along similar lines. [ABSTRACT FROM AUTHOR]

The use of fiber-reinforced composite materials for the construction and rehabilitation of civil engineering structures is relatively new. Structural members are routinely joined by bolted connections. Bolted connections are relatively easy to assemble and maintain, and are capable of transferring the high loads that typically occur in civil engineering structures. Currently there is a serious lack of knowledge on the behavior and design of bolted connections for fiber-reinforced composites. In light of this, a comprehensive experimental and analytical investigation was conducted at the University of Manitoba to study the behavior of bolted connections in composite materials appropriate for civil engineering applications. A total of 102 single-bolt connections were tested up to failure. The various parameters investigated were the width of the structural member, the edge distance, the thickness, and the direction of the fibers with respect to the applied load. The experimental program also included comprehensive material testing to determine the various in-plane material properties. This paper discusses the experimental program, test results, and various modes of failure as affected by the foregoing parameters. From the test results an analytical model and design procedure were developed as proposed in a companion paper. [ABSTRACT FROM AUTHOR]

Abstract: An extensive research project is currently being carried out at the University of Manitoba, Canada, involving the development of glass fiber-reinforced polymer (GFRP) wind turbine towers. The towers consist of multi-cell segments, each segment constructed from eight filament wound cells jointed together with resin applied over their interface. The present paper mainly addresses the static and dynamic characteristics, such as failure static loads, modes of failure, fundamental frequencies and periods of such segmented composite towers. Both experimental and numerical results are presented. The experimental investigation involved the testing of two jointed scaled towers. These specimens had a total height of 4.88-m (16-ft) and were tested as cantilevers under static and dynamic loading. The testing was conducted at the W.R. McQuade Structural Engineering Laboratory of the University of Manitoba. Finally, finite element models were developed to analyze the structural behavior, static and dynamic, of single and multi-cell composite segments and towers. The results from the finite element models under static loading were validated through comparison with the experimental results. [Copyright &y& Elsevier]

The performance of multiple-input multiple-output (MIMO) systems using beam selection is investigated in this paper. Based on the results of a channel sounding campaign carried out at the University of Manitoba for line-of-sight (LOS) and non-line-of-sight (NLOS) scenarios, it was possible to contrast the results of transmitter, receiver and joint beam selection in rich scattering environments. The channel was characterized in the 1-2.4 GHz frequency band with a multipath delay resolution better than 5.8 ns. The beam selection was performed by exhaustive search method. The results led us to important conclusions regarding the beam selection procedure and its potential to improve the indoor channel capacity. In LOS, the single input single output (SISO) system that favours the maximum power direction of arrival (DOA) maximizes the capacity. Capacity improvements are observed by increasing the number of receiver beams (RBs) only at high signal-to-noise ratios (SNRs) for omnidirectional transmission. The best performance in transmitter beam selection in LOS is observed by increasing the number of transmitter beams (TBs) for high SNRs. In the case of NLOS, the capacity performance is improved when more than a single beam is used in either, transmitter or receiver side. The joint transmitter-receiver beam selection exhibits best capacity performance only for large SNRs in LOS while the SISO systems outperforms any joint beam selection alternative for low SNRs. In contrast, in NLOS environments, the use of joint beam selection shows a constant capacity performance improvement starting from lower SNR than in the LOS case. [ABSTRACT FROM AUTHOR]

All wood utility poles require an effective maintenance program to ensure safe and reliable service. The end of a wood utility pole's useful life can be attributed to several factors, including decay, mechanical damage, weathering, and changing design requirements. Pole life can be extended through an effective preservative treatment and maintenance program, but all poles will reach a point when they are no longer suitable for their intended use. With the increasing cost of quality wood for use in poles, along with environmental concerns regarding pole disposal and chemical treatment of existing poles, new innovative methods are required to restore and maintain the structural integrity of existing wood poles. This paper presents results from a research program carried out at the University of Manitoba to develop a repair and rehabilitation technique for wood poles using fibre-reinforced polymers (FRP).

The article presents an interview with 20th century intellectual activist Graham Spry. He mentions his involvement in the 1919 Winnipeg, Manitoba labor strike. Spry believed that the newspaper "Manitoba Free Press," in which he was a longtime employee, dominated the paper industry then as well as now. He also comments about the political leanings of the various newspapers of the time.
