This dissertation examines the wealth effects of bank mergers on bidder, target, and combined firm shareholders for a sample of 785 mergers during the period 1980-2000. The dissertation employs two unique bank event study methodologies to calculate abnormal returns for bidder, target and combined firms. The first methodology is a modified market model that controls for shocks common to the banking industry. The second is an EGARCH (1,1) model that adjusts for the violated regression assumptions of the traditional market model event study. Namely, it controls for the linearity assumption, heteroskedasticity, and the correlation in the error term. The results of both methodologies reveal that target shareholders enjoy significantly positive abnormal returns, whereas the bidder shareholders experience significantly negative abnormal returns. Overall, announcements of bank mergers generate positive wealth effects for the combined shareholders. However, the evidence presented in this dissertation, to some extent, underscores the importance of the choice of models describing stock returns in examining the impact of bank mergers. In addition, when mergers are analyzed to determine the effects of relative size and relative book-to-market values, we find evidence that the relative size significantly affects the target, bidder and combined firm return; method of payment is also found to be significant in abnormal returns. Moreover, we find that the number of bidders affects only the bidder returns, while book-tomarket values are irrelevant factors. Availability Restricted: Release the entire work for campu

Fertilizer phosphorus (P) application rate and method are anticipated to have important influences on crop utilization and concentration and distribution of residual P in soil. This, in turn, can influence the amount of P removed in run-off water. The objective of this thesis work was to assess the influence of fertilizer P application method and rate on soybean (Glycine max (L.)) emergence, yield, and P uptake. Additionally, the forms and distribution of residual soil P following a season of crop growth, and the off-site export of applied P in simulated snowmelt run-off water was assessed. In a controlled environment study, soybean could tolerate up to 20 kg P2O5 ha-1 placed in the seed-row without significant reduction in emergence. Soybean was grown in a field study in 2014 in south-central Saskatchewan. Two sites were utilized within the same wheat stubble field (Downslope and Upslope) where fertilizer P was soil applied in the spring (seed-placed, deep band, and broadcast and incorporated) at 20 kg P2O5 ha-1 and broadcast at three rates (20, 40, and 80 kg P2O5 ha-1), along with a control treatment receiving no fertilizer P. At the Downslope position, in-soil application of fertilizer P resulted in a greater soybean yield and P uptake than broadcast application. After harvest, higher labile P concentrations were found in the zone of fertilizer P placement in the soil. Elevated concentrations of water soluble P were noted near the soil surface with broadcast P application compared to in-soil placement methods, attributed to immobility of P and lower plant utilization. A simulated snowmelt run-off event was conducted on intact soil slabs removed from the Upslope position treatments. Fertilizer P application method had a significant influence on P export with the greatest export occurring with broadcast application. Phosphorus XANES spectroscopy provided further evidence that, qualitatively, fertilizer P application method influenced speciation of fertilizer P reaction products in calcareous soil common to the Canadian prairies. Overall, it is concluded that in-soil placement of P fertilizer is a beneficial management practice in a prairie soil to maximize agronomic benefit while minimizing potential transport of fertilizer P off the field in snowmelt run-off water.

The current research was undertaken to determine the long run performance of Initial Public Offerings (IPOs) listed on the Johannesburg Stock Exchange (JSE) in South Africa. The three year abnormal returns were assessed for IPOs listed between 1995 and 2006 comprising a sample of 229. Using the Buy and Hold Abnormal Return (BHAR) and Cumulative Abnormal Return (CAR) methods, it was found that the IPOs underperformed the market by 50% and 47% for BHAR and CAR respectively. The JSE All Share Index was used as a benchmark. The research also investigated the effect of firm size on IPO performance. The relationship between IPO activity and performance was analysed as well as the performance of IPOs from different sectors. Gross proceeds of the offers were used as a proxy for firm size and it was shown that by splitting the sample into different size groups, there were significant differences between the returns from these groups. There was no relationship found between IPO activity and performance using a linear regression. Using an Analysis of Variance (ANOVA) it was determined that there were significant differences between the performance of IPOs in the different sectors of technology, industrials, financials and mining.

An experimental study of condensate was performed by exposing a sheet of glass, cooled at its bottom edge, to an enclosure with a controlled environment. The air in the enclosure was maintained at a constant relative humidity (RH) and a constant dry bulb temperature (Tdb). Experiments were conducted at Tdb = 22.1°C and RH of 30%, 35%, 40%, 45%, and 50%. It was found that the time until initial condensation run-off was sensitive to low RH (RH = 30%, 35%, 40%) and insensitive to high RH (RH = 45%, 50%). Time until run-off decreased with increasing RH. It was found that, at first, condensation run-off occurred near the bottom of the glass and left one to believe that the remaining condensate was in steady state with the enclosure. Over a 16 hour period however, it was found that the condensation run-off front, in every case, progressed upward to include the entire condensate area. Similar to time of initial run-off, speed of condensation front movement increased with RH and was also insensitive at high RH. A summary plot showing run-off front position is presented. This chart can be used to predict initial run-off and front progression at the bottom edge of any window if the surface temperature profile is known.
