Low temperature (77K) linear dichroism spectroscopy was used to characterize pigment orientation changes accompanying the light state transition in the cyanobacterium, Synechococcus sp. pee 6301, and cold-hardening in winter rye (Secale cereale L. cv. Puma). Samples were oriented for spectroscopy using the gel squeezing method (Abdourakhmanov et aI., 1979) and brought to 77K in liquid nitrogen. The linear dichroism (LD) spectra of Synechococcus 6301 phycobilisome/thylakoid membrane fragments cross-linked in light state 1 and light state 2 with glutaraldehyde showed differences in both chlorophyll a and phycobilin orientation. A decrease in the relative amplitude of the 681nm chlorophyll a positive LD peak was observed in membrane fragments in state 2. Reorientation of the phycobilisome (PBS) during the transition to state 2 resulted in an increase in core allophycocyanin absorption parallel to the membrane, and a decrease in rod phycocyanin parallel absorption. This result supports the "spillover" and "PBS detachment" models of the light state transition in PBS-containing organisms, but not the "mobile PBS" model. A model was proposed for PBS reorientation upon transition to state 2, consisting of a tilt in the antenna complex with respect to the membrane plane. Linear dichroism spectra of PBS/thylakoid fragments from the red alga, Porphyridium cruentum, grown in green light (containing relatively more PSI) and red light (containing relatively more PSll) were compared to identify chlorophyll a absorption bands associated with each photosystem. Spectra from red light - grown samples had a larger positive LD signal on the short wavelength side of the 686nm chlorophyll a peak than those from green light - grown fragments. These results support the identification of the difference in linear dichroism seen at 681nm in Synechococcus spectra as a reorientation of PSll chromophores. Linear dichroism spectra were taken of thylakoid membranes isolated from winter rye grown at 20°C (non-hardened) and 5°C (cold-hardened). Differences were seen in the orientation of chlorophyll b relative to chlorophyll a. An increase in parallel absorption was identified at the long-wavelength chlorophyll a absorption peak, along with a decrease in parallel absorption from chlorophyll b chromophores. The same changes in relative pigment orientation were seen in the LD of isolated hardened and non-hardened light-harvesting antenna complexes (LHCII). It was concluded that orientational differences in LHCII pigments were responsible for thylakoid LD differences. Changes in pigment orientation, along with differences observed in long-wavelength absorption and in the overall magnitude of LD in hardened and non-hardened complexes, could be explained by the higher LHCII monomer:oligomer ratio in hardened rye (Huner et ai., 1987) if differences in this ratio affect differential light scattering properties, or fluctuation of chromophore orientation in the isolated LHCII sample.

This thesis argues that the motivations underpinning the mainstream news media have fundamentally changed in the 21 sl century. As such, the news is no longer best understood as a tool for propaganda or agenda setting; instead it seems that the news is only motivated by the flow of global network capitalism. The author contrasts the work of Noam Chomsky and Edward S. Herman with that of Gilles Deleuze. Chomsky and Herman's 'Propaganda Model' has been influential within the fields of media studies and popular culture. The 'propaganda model' states that the concentration of ownership of the media has allowed the media elite to exert a disproportionate amount of influence over the mass media. Deleuze, on the other hand, regards the mass media as being yet another cog within the global capitalist mechanism, and is therefore separate from ideology or propaganda. The author proposes that 'propaganda' is no longer a sufficient word to describe the function of the news as terms like 'propaganda' imply some form of national sovereignty or governmental influence. To highlight how the news has 'changed from an instrument of propaganda to an instrument of accumulation, the author compares and contrasts the· coverage of the Abu Ghraib Prison Scandal with that of the Haditha Civilian Massacre. Although similar in nature, the author proposes that the Abu Ghraib Prison Scandal received a disproportionate amount of coverage within the mainstream press because of its exciting and sensational nature.

A photograph of Robert Bell (kneeling, front row, third left) with his airborne regiment in the Second World War. The date and location of the photo is unknown. This photograph was among those recovered from the attic of Iris Sloman Bell, of St. Catharines, in the 1980s and kept in the possession of her son, Rick Bell. The Bell- Sloman family is descended from former Black slaves from the United States.

Full title is "A Full and Correct Account of the Chief Naval Occurrences of the Late War Between Great Britain and the United States of America; preceded by a Cursory Examination of the American Accounts of their Naval Actions Fought Previous to that Period: to Which is Added an Appendix; with Plates" This is an expanded version of author William James' pamphlet "An Inquiry into the Merits of the Principal Naval Actions between Great Britain and the United States." (Halifax, Nova Scotia, 1816) In this work he discussed how American ships, during the War of 1812, were larger and more heavily armed and manned than those of the British. He therefore, stated that American victories were due only to their greater numerical force and not their superior seamanship. Naval Occurrences is a thorough documentation of the naval operations from the British perspective that addresses contradictions and inconsistencies within the American official documents as well as political and media accounts. This is perhaps his motivation for the words "Corrected Account" within the title. James' sentiments towards the US most likely sprouted from being held prisoner while visiting in 1812. (He was falsely accused of being a renegade seeking revenge on the US.) In 1813, he escaped to Halifax where he began writing on various naval topics. James became one of the leading authorities on British Naval History.
