Power structure under Marcus Aurelius
Recent years have produced quite a few biographies of Marcus Aurelius; of varying quality they all follow the chronological line of the encyclopaedias and none
penetrates deeply into the reign. Two Frenchmen, Charles Parain and Pierre de Proyart, both uncritical in their indiscriminate use of sources uncited, especially the Historia Augusta, overemphasize the concept of Marcus as the philosopher king. So does A.S.L.
Farquharson. This is a heritage from Marcusâ own Meditations. Only rarely are the utterances of emperors extant in literary sources; care in interpretation is
essential when they do appear, as in the res gestae of Augustus or in the letters of Trajan to Pliny. In Marcusâ case his philosophical theorizing has often
led to a false evaluation of his political activities. Fr.Carrata Thomes gives more emphasis to him as a political figure, but his biographical account of the reign incorporates little of the abundant prosopographical material available. Indeed there seems to be no detailed systematic treatment of internal politics
under the Antoninus, though individuals receive elucidation from such prosopographical experts as Groag, Syme, Pflaum, Carcopino, Lambrechts and E.
Birley. To these men and to the methods refined by them this work naturally owes much
The photochemical properties of arene metal carbonyl complexes of group 6 and 7 elements
The aim of this work was to determine the photochemical properties of a number of compounds of the general type (r|x-arene)M(CO)3 (M=Cr, Mn, X = 5,6). A range of techniques were used including ultraviolet/visible flash photolysis, time resolved infrared spectroscopy and matrix isolation.
The first chapter contains a literature survey of the group 6 and 7 metal carbonyl complexes, also presented is a brief description of the role of transition metal complexes in some important industrial processes. In addition, the metal carbonyl bond and the metal arene bond are described, while the nature of the absorption spectra of group 6 and 7 metal carbonyls are discussed, as are their known photochemical and thermal properties.
The second chapter describes the photochemistry of functionalised (r|6-C6H5X)M(CO)3 Complexes ( X = OCH3, NH2, CO2CH3 or C(O)H). The nature of the functionality on the arene ring has been shown to affect the photochemical properties of these complexes. The relative importance of CO loss versus arene loss is measured and these observations are explained in terms of electronic character of the arene substituent.
The third and fourth chapters deal with the photochemistry of a series of compounds which are used to model the hydrodesulphurisation reaction, namely (ri5-thiophene)Cr(CO)3, (r]6-benzothiophene)Cr(CO)3, (r|6-dibenzothiophene)Cr(CO)3 and (r|5-selenophene)Cr(CO)3. Both steady state photolysis and time-resolved techniques were used to investigate the photochemistry of these complexes. In addition to CO loss, evidence of a hapticity change from r|5 to r|4 is observed for (ri5-thiophene)Cr(CO)3 and (r|5-selenophene)Cr(CO)3 under photochemical conditions.
This research was also extended to group 7 metal carbonyls. The fifth chapter deals with the photochemistry of (r]5-pyrrollyl)Mn(CO)3. While CO loss was observed as the dominant photoprocess, evidence for a ring-slip process was also obtained. The sixth chapter details the different synthetic procedures used, as well as the experimental techniques of ultraviolet/visible flash photolysis, time resolved infrared spectroscopy and matrix isolation techniques

An Assessment of the Economic, Environmental and Social Impacts of NSW Agriculture's Wheat Breeding Program
The Wagga wheat breeding program has been operating for over 100 years. In that time, it has released a flow of new wheat varieties for wheat growers in south-eastern Australia. Those varieties have led to increases in both yields and grain quality. The average annual rate of yield improvement in NSW has been 3.2% compared to the average for Australia of 2.4% with a significant proportion of these productivity gains arising from new varieties. In this analysis, the investment in that program from 1980 to 2003 has been evaluated. Given the lags inherent in wheat breeding investments, the benefits from those investments are being measured from 1993 to 2020. The broad structure of the program has remained relatively stable for most of the period since 1980. The program consists of 2-3 wheat breeders, one breeder-pathologist, and a cereal chemist, with appropriate technical and field support, totaling approximately 15 full-time equivalents per year. The costs of the program have averaged approximately 321 million. The economic benefits of the breeding program are shared by producers, processors and consumers in the wheat industry, some of whom live overseas. Because Australia is largely a price taker on world wheat markets and because the wheat processing and distribution sector in Australia is generally considered to be competitive, most of the benefits of the wheat breeding program are likely to remain with producers. However these gains are offset by declines in the world price in response to advancing technology throughout the world. These economic benefits have positive social consequences, largely through their contribution to the incomes of farmers and those who handle and process wheat in regional NSW. Some of these gains are in the form of new marketing and processing industries around the increasingly specialised industry segments resulting directly from the changes that have occurred in wheat varieties. Perhaps these new skills add to the social capital of towns in the wheat belt of NSW. In environmental terms, the wheat breeding program itself is not likely to have major impacts, since the wheat industry would have been very similar whether or not there was a Wagga breeding program. However, to the extent that improved productivity from the Wagga program's varieties has allowed an expansion of the wheat industry, there could be some negative environmental consequences of the breeding program, such as those arising from the clearing of land, increased cultivation and increased use of herbicides. On the other hand, the high levels of disease resistance developed and maintained has meant that wheat production is not associated with large-scale fungicide use, and hence the danger of chemical contamination of the environment is less than it would have been without the resistance developed in this program. Some of these environmental impacts affect the costs and incomes of wheat farmers and hence are reflected in economic benefits and some spill over to the broader community and have not been valued here. It is not clear that these social and environmental impacts would be much different without the Wagga breeding program, except through the extent to which the Wagga program has allowed the wheat industry in NSW to develop more than it otherwise would have. Without the Wagga program the slower gains in yield and quality would also be associated with some social and environmental impacts, and it is the difference that is critical in evaluating the Wagga program. The costs of this program have been met partly by the NSW taxpayers through NSW Agriculture and partly by the grains industry through levies from the Grains Research and Development Corporation (GRDC). The recent introduction of variety royalty payments ("end-point royalties") has not yet led to significant funding, but may be expected to do so in the future. The nature of the outputs of plant breeding programs is that there are large economic benefits that flow directly to producers, processors and consumers in the industry. However the social and environmental impacts on the broader community, while not explicitly valued here, are considered to be small relative to economic benefits and relative to some other programs of NSW Agriculture that have been evaluated. Hence it is appropriate that the industry, though GRDC levies and royalties on production, has increasingly funded the operations of the wheat breeding program. Recent institutional changes for the wheat breeding program have made it even more commercially-based for the future and less reliant on government funding. The new institutional arrangements for wheat breeding programs and the strengthening role of the private sector in supplying varieties traditionally supplied by the public sector mean that the place of public wheat breeding programs is being re-assessed. A key question is whether publicly-operated programs, can offer some additional benefits either to the industry or to the community, which would not result from the complete privatisation of the wheat breeding sector. While those issues have not been addressed directly in this analysis, the results indicate that past investments in public wheat breeding program at Wagga have certainly been a productive use of public funds over the past 20 years or so.Research and Development/Tech Change/Emerging Technologies,
The Process of Adaptation in Inter-Firm Relationships
Ross Brennan and Peter W. Turnbull, 'The Process of Adaptation in Inter-Firm Relationships, in Proceedings of the 12th annual IMP Group conference, presented at Interaction, Relationships and Networks, University of Karlsruhe, Germany: IMP.Adaptations are an important, arguably a defining, component of a long-term buyer-seller relationship. Substantial research evidence exists on the nature of the adaptations which arise within such relationships. The processes involved in adapting for a customer or supplier organisation are not so well understood. Five process metaphors for adaptation within buyer-seller relationships are explored. Each is found helpful to some extent in illuminating the process of adaptation. The metaphors are found to be complementary, so that taken together they provide a coherent process view of buyer-seller adaptations.Final Published versio
