Since the early 1970's, Canadians have expressed many concerns about the growth of government and its impact on their daily lives. The public has requested increased access to government documents and improved protection of the personal information which is held in government files and data banks. At the same time, both academics and practitioners in the field of public administration have become more interested in the values that public servants bring to their decisions and recommendations. Certain administrative values, such as accountability and integrity, have taken on greater relative importance. The purpose of this thesis is to examine the implementation of Ontario's access and privacy law. It centres on the question of whether or not the Freedom of Information and Protection of Privacy Act, 1987, (FIPPA) has answered the demand for open access to government while at the same time protecting the personal privacy of individual citizens. It also assesses the extent to which this relatively new piece of legislation has made a difference to the people of Ontario. The thesis presents an overview of the issues of freedom of information and protection of privacy in Ontario. It begins with the evolution of the legislation and a description of the law itself. It focuses on the structures and processes which have been established to meet the procedural and administrative demands of the Act. These structures and processes are evaluated in two ways. First, the thesis evaluates how open the Ontario government has become and, second, it determines how Ill carefully the privacy rights of individuals are safeguarded. An analytical framework of administrative values is used to evaluate the overall performance of the government in these two areas. The conclusion is drawn that, overall, the Ontario government has effectively implemented the Freedom of Information and Protection of Privacy Act, particularly by providing access to most government-held documents. The protection of individual privacy has proved to be not only more difficult to achieve, but more difficult to evaluate. However, the administrative culture of the Ontario bureaucracy is shown to be committed to ensuring that the access and privacy rights of citizens are respected.

S1 to S3 excited singlet state absorption and two-photon absorption in Rhodamine 6G at the pump wavelengths of 532 and 1064 nm respectively are investigated. The advantages of employing the pulsed photoacoustic technique for conveniently observing excited singlet state absorption are discussed. It is shown that, since photoacoustics and fluorescence are complementary phenomena, analysis using both techniques will yield a better understanding of optical processes in molecules like Rhodamine 6G.

The split-pulse laser method is used to reinvestigate the optical attenuation of distilled water in the region from 430 to 630 nm. The studies are then extended to ionic solutions of NaCl, MgCl2, and Na2SO4, these salts forming the major constituents of seawater. The effect of the concentration of these constituents on optical attenuation is investigated. Further, optical attenuation studies are carried out for the region from 430 to 630 nm for an aqueous solution prepared with all the major constituents in the same proportions as in natural seawater. These values are then compared with values obtained for natural seawater. The relative role of dissolved salts and suspended particles on optical attenuation in seawater is discussed. The lowest attenuation is observed at ~450 nm for all solutions and is found to coincide with that for distilled water.

Relatively oxygen-free mesoporous cubic ZnS particles were synthesised via a facile solvo-hydrothermal route using a water–acetonitrile combination. Boosted UV emission at 349 nm is observed from the ZnS prepared by the solvo-hydrothermal route. The increased intensity of this UV emission is attributed to activation of whispering gallery modes of almost elliptical microstructures made of porous nanostructures.
