Gathering for God : George Brown in Oceania

Combining 'the gathering of artefacts with the gathering of souls', George Brown was a key figure in the Christian, and especially the Wesleyan Methodist, history of nineteenth-century Oceania. Using his life as a case study, Helen Bethea Gardner examines the role of Christian missionaries in the Pacific Islands. Brown's career (1860-1908) spanned one of the most tumultuous political periods in the South Pacific, as one by one islands were colonised by imperial nations. He was one of the most politically engaged of all missionaries, encouraging colonial rule in the Pacific by America, Britain, Germany and, eventually, Australia and New Zealand. Originally from the north of England, he worked as a missionary in Samoa from 1860, moving to the Bismarck Archipelago (now Papua New Guinea) in 1875. From the 1880s until his retirement in 1907, he worked in Sydney as the general secretary of the Australasian Methodist Overseas Mission. Gathering for God examines Brown's missionary letters, journals and journalism, exploring how he attracted Pacific Islanders to Christian teachings, analysing his leadership during an armed attack on New Britain villages accused of cannibalism, and looking at his work in the new discipline of anthropology. He was a major collector of artefacts (his collection is now in the Osaka Museum) and photographer of Pacific peoples (his collection is in the Australian Museum).

Polycyclic aromatic hydrocarbon emission loads and profiles from the burning of locally grown wood species in Victoria, Australia - Some pilot project results

A testing facility for combustion of biomass and sampling of emissions has been established at Deakin University. In this pilot project using this facility, four kinds of locally grown wood species were burned and the particle emissions sampled and analysed for Polycyclic Aromatic Hydrocarbons (PAHs). The selected wood species covering pine, red gum, yellow box and sugar gum, are the most popular domestic fuel wood in Australia. Particulate matter emissions from burning of each load of wood were sampled from the flue using a standard stack emission sampling train. The particle-laden filters were extracted and the .extract analysed to determine PAH concentrations by Gas Chromatographyl Mass Spectrometer (Gc/MS). The sampling was conducted under two different burning conditions with the air inlet of the combustion chamber fully open and with it half open. A suite of 15 PAHs, ranging from naphthalene (C IOHB) to dibenzolahlanthracene (C12H14), were selected for analysis. PAH profiles for the four wood species, under the different burning regimes, have been generated. Some preliminary emission factors for the different wood species have been derived as microgram of summed PAHs (rPAHs) emittedlkilogram of wood burned. Total Particulate Matter (TPM) emission factors were also obtained from gravimetric measurement of the sample filter before and after the combustion. Based on these emission factors, pine displayed the highest level of rPAHs emitted from the combustion of the four wood species, with sugar gum showing the lowest level of rPAHs emission. Emission factors associated with the slow burning condition clearly showed higher l:PAH levels compared to the faster burning condition. During the faster burning condition, red gum and pine show a higher percentage of rPAH to TPM than sugar gum or yellow box. Under the slower burning. the l:PAHlTPM ratio in every case was greater.

Global review of permian Tyloplecta muir-wood and cooper, 1960 (Brachiopoda): morphology, palaeobiogeographical and palaeogeographical implications

A global review of the stratigraphical and geographical distribution of Tyloplecta reveals that the genus ranges in age from Kungurian to Changhsingian (Middle to Late Permian). Tyloplecta first evolved in South China in the Kungurian (late Early Permian). The genus went through its first diversification in the Guadalupian, suffered a major extinction at the end of the Guadalupian, and re-diversified in the Wuchiapingian. T. yangtzeensis persisted into the Changhsingian as the only survivor of the genus involved in the end-Permian mass extinction. Palaeogeographically, South China is not only the centre of origin for the genus but also an area of diversification and evolution. In addition to South China, Tyloplecta has also been recorded from the Far East Russia, Japan, central Thailand, Laos, Cambodia, Qiangtang Terrane of Tibet, Salt Range, Iran, Armenia, Hungary, Yugoslavia, and Slovenia. This geographic spread suggests that Tyloplecta was primarily restricted to the Palaeotethys and is indicative of warm-water palaeoequatorial conditions. Its presence in some of the northeast Asian terranes (e.g., parts of Japan and Far East Russia) and in the Salt Range (Pakistan) and central and north Iran (part of the Cimmerian microcontinents) demonstrate that the genus invaded the middle palaeolatitudinal regions in both hemispheres during the late Middle Permian in response to increased shallow marine biotic communications between Cathaysia in the eastern Palaeotethys and southern Angaraland, and between Cathaysia and Peri-Gondwanaland. The invasion of Tyloplecta (and some other taxa) into the southern shore waters of Angaraland may be explained by assuming ocean surface current connections and close palaeogeographical proximities between the South China, Sino-Korea and Bureya blocks. In comparison, the invasion of Tyloplecta into the Peri-Gondwanaland region is more likely a result of reduced palaeogeographical distance between South China and Peri-Gondwanaland and the appearance of the Cimmerian microcontinents as migratory stepping stones.

Study of polycyclic aromatic hydrocarbons emissions from burning of local wood species in Australia

Four kinds of Australian local wood species were burned in a domestic wood heater installed in a laboratory. The selected wood species include pine, red gum, yellow box and sugar gum, that are the most popular domestic fuel wood in Australia. Particulate matter emissions from burning of each load of wood were sampled isokinetically on filter media from the flue by standard stack emission sampling train. The particle laden filters then went for Gas Chromatography/ Mass Spectrometer (GC/MS) analysis to determine polycyclic aromatic hydrocarbons (PAHs) concentrations. The sampling was conducted under two different burning conditions – air inlet of the combustion chamber fully open and half open. Approximately 15 types of PAHs were detected. Emission factors were derived as microgram of PAHs /kg of wood burned. Total particulate emission factors were also obtained from gravimetric measurement before and after the sampling. PAH emission profiles for four species were generated from the results. Comparisons of emission factors have been conducted among different species of wood, as well as under different burning conditions, ie. fast burning and slowing burning. According to the derived emission factors, pine displayed the highest level of PAHs among the four species, followed by red gum and yellow box, whereas sugar gum showed the lowest level of PAHs. Emission factors were compared between each type of wood under two different burning conditions, the slow burning condition, which was air inlet half open, clearly showed higher PAH levels compared to the fast burning condition. Total PAH fractions on particulate matter were calculated and compared among wood types under two burning conditions. During the fast burning condition, red gum and pine have the higher percentage of PAH to total particulate matter emission than sugar gum and yellow box. When changed to slow burning, the PAH fraction on particulate matter are all increased with sugar gum having the largest increase.

Improved questionnaire for gathering student perceptions of teaching and learning

An instrument used to gather university students’ perceptions of their learning environments, the Perceptions of Learning Environments Questionnaire (PLEQ) has been used recently in higher education research. The current paper examines the strengths and limitations of the PLEQ, particularly in relation to uncovering student perceptions about responsibility for their own learning. A study trialling a modified questionnaire, which
builds on the advances and addresses the limitations of the PLEQ, is reported.

Embodied energy in buildings : wood versus concrete - reply to Börjesson and Gustavsson

We analyse the wood and concrete designs of the Wälludden building described by Börjesson et al. (Energy Policy 28 (2000) 575) in terms of their embodied energy, employing an environmentally extended input–output framework in a tiered hybrid life-cycle assessment, and in a structural path analysis. We illustrate the complexity of the inter-industry supply chains underlying the upstream energy requirements for the building options, and demonstrate that higher-order inputs are difficult to capture in a conventional process analysis. Our calculations show that Börjesson and Gustavsson's estimates of energy requirements and greenhouse gas emissions are underestimated by a factor of about 2, and that corresponding greenhouse gas balances are positive at about 30 t C-eq. Nevertheless, Börjesson and Gustavsson's general result—the concrete-framed building causing higher emissions—still holds.

An agent-based intelligent system for information gathering from world wide web environment

To use the vast amount of information efficiently and effectively from Web sites is very important for making informed decisions. There are, however, still many problems that need to be overcome in the information gathering research arena to enable the delivery of relevant information required by users. In this paper, an information gathering system is develop by means of multiple agents to solve those problems. We employed some ideas of Gaia's methodology and an open agent architecture to analyze and design the system. The system consists of a query preprocessing agent, information retrieval agent, information filtering agent, and information management agent. The filtering agent is trained with categorized documents and can provide users with the necessary information. The experimental results show that all agents in the system can work cooperatively to retrieve relevant information from the World Wide Web environment.

LAN cafes: cafes, places of gathering or sites of informal teaching and learning?

Despite the interest of sociologists and educational researchers in Internet café as sites for new cultural and social formations and informal learning, thus far little attention has been paid to the function of café owners, managers and other staff in the mediation and co-construction of those spaces. Drawing from interviews with managers of commercial Internet café in Australia specialising in LAN (Local Area Network) gaming, this article seeks to examine their role and their attitudes more closely; in particular with regard to school-aged users of their facilities. We contend that LAN café are liminal spaces situated at the margins of Australian culture and located at the junctions between home, school and the street, online and offline spaces, work and play. The roles of LAN café managers are similarly ambiguous: in many ways they can be regarded as informal teachers facilitating the process of informal learning.

Thermal evaluation of a low cost wood burner

Small-scale producers of dried products in rural areas of developing countries must often rely on sun drying to dry their crops, but this can be unreliable and produce an inferior product. There is therefore a need for simple and inexpensive combustion devices that can be fabricated and used locally. A wood burner has been constructed from a "200 litre" steel drum and has then been evaluated experimentally. The thermal efficiency of the burner was found to be 31% in two trials. An energy balance, calculated for three trials, was within + 16%. Approximately one third of the energy available in the wood was lost in the flue gases, either as sensible heat or unburned volatile gases. Excess combustion air through the burner was calculated and measured to be approximately 400% of the stoichiometric requirements. A significant amount of energy was required to heat the thermal mass surrounding the burner, indicating that a lightweight insulated structure would be more suitable in most circumstances.

Codes of ethics in large private sector Australian businesses

This thesis deals with codes of ethics in the top 500 companies operating in the private sector in Australia. We seek to answer two questions. First, can businesses adopt codes of ethics in a meaningful way, or are business ethics a contradiction in terms for profit seeking organisations in competitive markets? Second, to what extent do Australia’s top 500 private sector firms show commitment to codes of ethics? A number of ancillary questions are explored to form a picture of the current Australian situation and to compare it to the rest of the world, especially the US and Canada. Chapter 1 discusses these questions and the origins of the author’s interest in business ethics. This chapter develops a focus upon codes of ethics and their role in assisting to establish and maintain an ethical culture. The chapter looks at previous research on codes of ethics and demonstrates a lack of understanding in Australia on the subject and the need for research into it. Also included in Chapter 1 is the plan for the thesis. Chapters 2 to 4 review the literature upon which the thesis is based. In Chapter 2, the meaning of the terms ethics and business ethics are considered. Deontological and teleological approaches are distinguished and a (largely) teleological model of business ethics is developed. This chapter also asks whether business ethics are possible. The contention that ethics may be good for a business’s profit is explored in-depth and the conclusion is reached that ethics should be pursued for its inherent worth regardless of the economic benefit that can be attributed to it. A number of models of ethical decision making are discussed in Chapter 3 starting with Kohlberg and Kramer (1969). This discussion leads to the conclusion that organisations must create an ethical culture for staff if they require them to embrace ethical practices. If this is a correct conclusion, then the role of senior managers becomes critical in the process. Chapter 4 looks further at the role of senior managers, organisational culture and ethical/unethical behaviour in organisations. The conclusion is that senior managers do play an integral part in shaping the culture of an organisation. Their actions, either overtly or covertly, impact upon their staff and highlight behaviour that the organisation is or is not willing to tolerate. Sims (1991) proposed ten ways to foster an ethical culture and these ideas are set out and further explored through the work of other writers on management ethics. Finally, the link between ethics and strategic planning is examined. In Chapter 5 the methods used for empirical data gathering are described and justified. A number of factors that can lead us to consider a company’s ‘commitment’ to ethics are outlined. A survey of Australian companies was the primary means of data collection. Each question in the survey instrument is listed and explained. Also the survey response rate is reported, as are major demographic characteristics of respondents. Chapter 6 provides the research findings from the survey of the top 500 companies operating in the private sector in Australia. The research examines: i) the current Australian usage and implementation of codes of ethics; ii) the measures put in place in organisations in order to support a code; From this analysis conclusions are drawn about the ‘commitment’ of companies operating in Australia to codes of ethics. Australian companies are becoming aware of the potential of code usage. Companies operating in Australia that have codes appear to be good at implementing codes and examining staff performance in relation to codes. However, they lack the procedures that incorporate education and training and the implementation of the support mechanisms necessary to enhance employee understanding of the code. In Chapter 7, Australian codes are compared to American and Canadian codes for similarity and disparity. The assessment found that in all three countries codes are primarily concerned with company continuance. Australian codes do tend to be more socially oriented than in the other two countries and also less legalistic. Chapter 8 looks at 4 companies from the first survey that were asked for more in-depth information in a quest to determine current best practice in Australia. These organisations were chosen because they appeared, from the first survey instrument, to have put in place mechanisms to assist employees to better understand the code. The implication is that companies must make a conscious, positive effort to ensure that employees are considered in the process of ethical development. They should have input into the process, rather than just being directed to follow another management initiative. The final chapter summarises the research findings and looks at answers to the two major questions and the seven subordinate empirical questions posed at the start of the thesis. The conclusion reached is that companies operating in Australia appear to be moving towards establishing codes of ethics. Those who already have codes display a real commitment to them. The movement appears to be gathering momentum as more organisations see the value of incorporating ethical business practices into the every day workings of their individual companies. Generally, most Australian companies lag behind the rest of the world, but the pace-setting companies are defining their own best practice and achieving positive outcomes for themselves, their employees and other stakeholders.
