“…Although the free radical mechanism which makes up the fatty acid autoxidation process has been thoroughly studied (1)(2)(3), one factor remains unsatisfactorily explained: the origin of the initial free radicals necessary to begin the process in an oil completely free of hydroperoxides (1,(4)(5)(6)(7). The oxidation process in the presence of air is usually assumed to be initiated by the breakdown, in some fashion, of hydroperoxides (8).…”

A mechanism for the initiation of autoxidation in fatty acids is proposed which involves singlet state oxygen, formed through a photosensitization reaction, as the reactive intermediate. Both singlet oxygen generated in a radio-frequency gasdischarge, and photosensitization by natural pigments, were shown to catalyze the oxidation of methyl linoleate. The involvement of singlet oxygen was shown by the identification of nonconjugated hydroperoxides as products common to both photooxidation and singlet O2 oxidation. Nonconjugated hydroperoxides could not be detected among the free radical autoxidation products. Further proof for the above mechanism was gained by showing that compounds known to react strongly with singlet oxygen, inhibited the photooxidation. With the exception of chlorophyll, all sensitizers could be completely inhibited. Although singlet oxygen formation can account for approximately 80% of the observed chlorophyll photooxidation, at least one other mechanism must be involved. It is postulated that proton abstraction by the photoactivated carbonyl group of chlorophyll could account for the remaining 20% of the observed photooxidation. The conclusion is drawn that oxygen, excited to its singlet state by a photosensitization process, plays the important role of forming the original hydroperoxides whose presence is necessary before the normal free radical autoxidation process can begin.

“…Even when the refugee documents are accepted by employers, various issues arise, such as access to banking 114 and access to unemployment insurance. 115 Similarly, the refugee documentation impacts refugees' education. The short duration of refugee and asylum seeker status makes it difficult to obtain admission or continue their studies at universities.…”

“…For those who were faithful to the Chicago School, however, the answer was almost always 'no' since the Chicago School tends to believe that barriers to entry are low such that new entrants can quickly emerge. 80 This shift in thinking is particularly evident in the 2003 decision of Boral Besser Masonry Ltd v Australian Competition and Consumer Commission which involved the supply of concrete masonry products-perhaps not the easiest industry for a new competitor to break into. 81 Boral involved a price war in the supply of such products in Melbourne.…”

Australia has a competition problem: there is not enough of it. Our industries are concentrated. Our markets show signs of weak competition. The way Australia’s courts, parliamentarians and regulators think about competition is partly to blame. Although it has been less influential in Australia than in the United States, the Chicago School’s views on competition have shaped our laws, policies and enforcement practices. The Chicago School views market concentration as a virtue more than a vice. The School contended that barriers to entry are negligible, market power is temporary, most mergers are good, vertical restraints and predatory pricing are either benign or efficient. The growing body of research and experience, however, shows that the Chicago School’s faith in the ability of markets to self-correct and deliver competitive outcomes was misplaced. There is a strong progressive case for repositioning how we think about competition. Focusing more on the competitive process, the structure of markets and the incentives those structures create for firms will play an important role in reducing inequality.
