Description: Some occupational health and safety hazards associated with sheep shearing are related to shearing shed design. One aspect is the floor of the catching pen, from which sheep are caught and dragged to the shearing workstation. Floors can be constructed from various materials, and may be level or gently sloping. An experiment was conducted using eight experienced shearers as participants to measure the force exerted by a shearer when dragging a sheep. Results showed that significant changes in mean dragging force occurred with changes in both surface texture and slope. The mean dragging forces for different floor textures and slopes ranged from 359 N (36.6 kg) to 423N (43.2 kg), and were close to the maximum acceptable limits for pulling forces for the most capable of males. The best floor tested was a floor sloped at 1:10 constructed of timber battens oriented parallel to the path of the drag, which resulted in a mean dragging force 63.6N (15%) lower than the worst combination.

Description: This article describes an argumentation shell to support the formulation, representation and drafting of legal arguments. The shell can be used to capture generic arguments in many legal domains as well as to assist decision-makers in constructing their own actual arguments . The shell demonstrates that knowledge represented using the generic/actual argument model (GAAM) (a variant of Toulmin's argument structure) can be used to: (a) support the development of complex arguments, (b) add context and increase specificity for the retrieval of relevant documents, (c) incorporate background knowledge, (d) assist in the drafting of documents that represent arguments made, and (e) provide a structure for complex inferences requiring a range of mechanisms. The shell can be used to support decision making in a range of legal domains, including discretionary domains.

An integrated approach to wallrock alteration in the Bendigo goldfield, Victoria, Australia

Authors: Swan, Haydn
Date: 2002
Type: Text , Thesis , Masters
Full Text:
Description: "Wallrock alteration associated with the world-class, vein-gold deposits of the Bendigo goldfield is more extensive than has been previously documented. Alteration is characterised by the development of a pervasive and extensive carbonate alteration halo, as well as a somewhat lesser sulphide alteration halo. Alteration features observed resulted from the passage of large volumes of hydrothermal fluids over a protracted period, with alteration features being centred on major structures that acted as the main fluid conduits. The location and history of the evolution of these structures was a dominant control on the location, intensity and extent of wallrock alteration developed."

Description: In attempting to eliminate disease caused by drinking polluted surface water, millions of shallow surface wells were drilled into the Ganges delta alluvium in Bangladesh. The latest statistics indicate that 80% of Bangladesh and an estimated 40 million people are at risk of arsenic poisoning-related diseases because the ground water in these wells is contaminated with arsenic. The clinical manifestations of arsenic poisoning are myriad, and the correct diagnosis depends largely on awareness of the problem. Patients with melanosis, leuco-melanosis, keratosis, hyperkeratosis, dorsum, non-petting edema, gangrene and skin cancer have been identified. The present article reviews the current arsenic contamination of ground water, hydrological systems, groundwater potential and utilization and environmental pollution in Bangladesh. This paper concludes by clarifying the main actions required to ensure the sustainable development of water resources in Bangladesh.

ATL>Effects of acetaldehyde on Saccharomyces cerevisiae exposed to a range of chemical and environmental stresses

Relation: Enzyme & Microbial Technology Vol. 30, no. 2 (2002), p. 240
Full Text: false
Description: The ability of small quantities of added acetaldehyde to stimulate growth in environmentally-stressed cultures of Saccharomyces cerevisiae was examined over a broad range of stress conditions. Acetaldehyde addition substantially reduced the lag phase of cultures suddenly inoculated into medium containing inhibitory quantities of low M.W. alcohols and higher fatty acids. For ethanol-stressed cultures, acetaldehyde was effective whether added initially or during fermentation. The effects of acetaldehyde were not universal, only minor stimulation being observed for cultures exposed to heat shock, or experiencing changes in cultivation temperature or pH, despite the occurrence of long lag phases under these conditions. Acetaldehyde strongly inhibited the growth of osmotically-shocked cultures, in contrast to the effects of small quantities of ethanol. The beneficial effects of acetaldehyde appear to be largely confined to cultures exposed to chemical stress especially by agents which disturb membrane structure or function. Acetaldehyde addition has potential practical application in overcoming inhibition in such fermentations. [Copyright 2002 Elsevier]

Description: A generalization of the Perron-Frobenius theorem to increasing positively homogeneous of degree one operators is extended to increasing co-radiant and topical operators, which are of interest in mathematical economics. In particular, small attracting sets containing the limit points of all sequences generated by iteration of such operators are determined.

Description: This study examined respondents' perceived level of blame and responsibility for three victims of rape, as a function of attitudes toward homosexuals, and perceived similarity to the victim, as indicative of Shaver's (1970) Defensive Attribution Hypothesis. Victims were a homosexual and heterosexual male, and a female. A sample of 168 university students completed questionnaires, which included three rape scenarios and subsequent questions, the Index of Attitudes Toward Homosexuals (Hudson & Ricketts, 1980), and the short-form Marlowe-Crowne Social Desirability Scale (Reynolds, 1982). Results indicated that respondents higher in homophobia (regardless of gender) blamed the homosexual male rape victim and the behavior and character of the heterosexual male rape victim, more than the female rape victim. Male respondents in general also blamed the heterosexual male rape victim, more than female respondents. Shaver's defensive attribution hypothesis was not supported. Results are discussed in terms of the possible link between homophobia and male rape blame. © 2002 by The Haworth Press, Inc. All rights reserved.

Aurora Leigh : Elizabeth Barrett Browning's novel approach to the woman poet

Authors: Tasker, Meg
Date: 2002
Type: Text , Book chapter
Relation: Tradition and the poetics of self in nineteenth-century women's poetry Chapter p. 23-41
Full Text:
Reviewed:
Description: "Tradition and how far writers fit into or diverge from the demands of tradition is one of the most debated issues in literary discussion. Gender, however, is not often part of discussions which depend on such questions at the decisiveness of the Modernist break with the Victorian period or whether Postmodernism makes tradition meaningless. By contrast the very existence of a specifically female tradition is still an urgent subject of debate, and it is clear that many nineteenth-century women writers were troubled in their search for literary foremothers. This autobiographical impetus can be located in the work of each of the poets discussed in Tradition and the Poetics of Self Nineteenth-Century Womens Poetry: Elizabeth Barrett Browning, Caroline Bowles Southey, Emily Dickinson and Christina Rossetti. An exploration of the self, either in the abstract or in a more closely personal sense, appears in a concern with the craft of poetry and the role of the poet, in a teasing out of language as a marker of a personal encounter with the world, in an adventurous play with genre and a rewriting of myth, and in a bold confrontation with received notions of a womans place. Adventurousness marks the work of each of these poets and is a central focus of these essays."

Description: In the 1920s and 1930s working-class people from the inner suburbs of Melbourne, Australia took to the foothills of the nearby Dandenong ranges on weekends and public holidays to enjoy a bush picnic or holiday. It was a time in both Britain and Australia when working people were able to take family holidays in greater numbers. Unstructured interviews with former female visitors began with the purpose of gaining an insight into the leisure of the time. Information obtained along the way about working lives reinforced the importance of thinking about work and leisure in association with each other. The incidents that some women remembered from their working lives presented a strong and autonomous view of themselves. While such power could be seen as a realistic view of their holidays in the bush, it appears that the context of the interview relationship contributed to the highlighting of an assertive and lively work identity.

Description: A tremendous amount of work and effort has been devoted to securing financial transactions over the Internet. However the amount of effort is not reflected in the number of people who are purchasing on the Web. This paper provides a conceptual model and framework for future empirical investigations as to why people are still apprehensive to purchasing on the Internet. The model is based on the development of perceptions of risk related to purchasing on the Internet and incorporates, product class, prior experiences with the product and purchasing online, and word of mouth (media reports) as determinants for risk. The model then provides Website design, with technology and information provided as moderators of the effect of perceptions of risk to the purchasing decision.
