A new South American network to study the atmospheric electric field and its variations related to geophysical phenomena

In this paper we present the capability of a new network of field mill sensors to monitor the atmospheric electric field at various locations in South America; we also show some early results. The main objective of the new network is to obtain the characteristic Universal Time diurnal curve of the atmospheric electric field in fair weather, known as the Carnegie curve. The Carnegie curve is closely related to the current sources flowing in the Global Atmospheric Electric Circuit so that another goal is the study of this relationship on various time scales (transient/monthly/seasonal/annual). Also, by operating this new network, we may also study departures of the Carnegie curve from its long term average value related to various solar, geophysical and atmospheric phenomena such as the solar cycle, solar flares and energetic charged particles, galactic cosmic rays, seismic activity and specific meteorological events. We then expect to have a better understanding of the influence of these phenomena on the Global Atmospheric Electric Circuit and its time-varying behavior.

Can agroforest woodlots work as stepping stones for birds in the Atlantic forest region?

In fragmented landscapes, agroforest woodlots can potentially act as stepping stones facilitating movement between forest fragments. We assessed the influence of agroforest woodlots on bird distribution and diversity in the Atlantic forest region (SE Brazil), and also tested which categories of species can use different types of connection elements, and whether this use is influenced by the distance to large forest patches. We studied two fragmented landscapes, with and without stepping stones linking large fragments, and one forested landscape. Using a point count, a bird survey was undertaken in the fragmented landscapes in five different elements: large remnants (> 400 ha), agroforest woodlots (0.4-1.1 ha), small patches (0.5-7 ha), riparian corridor, and pasture areas (the main matrix). Generalist and open-area species were commonly observed in the agroforest system or other connection elements, whereas only a few forest species were present in these connections. For the latter species, the distance of woodlots to large patches was essential to determine their richness and abundance. Based on our results and data from literature, we suggest that there is an optimal relationship between the permeability of the matrix and the efficiency of stepping stones, which occurs at intermediate degrees of matrix resistance, and is species-dependent. Because the presence of agroforest system favors a higher richness of generalist species, they appeared to be more advantageous for conservation than the monoculture system; for this reason, they should be considered as a management alternative, particularly when the matrix permeability requirement is met.

Critical factors influencing employment: a study of small manufacturing firms in South-East Australia

Compliance with legislation has been highlighted as a factor influencing the reluctance of small and medium sized enterprises to take on new employees. With the objective of determining factors influencing smaller firms in their employment decisions, mailed questionnaires were used to survey small to medium manufacturing businesses in the Australian States of Victoria and New South Wales. Significant critical factors and deterrents to further employment were identified.

Performativity, youth and injurious speech

Young people may become disengaged from schooling in the middle years for a multitude of reasons. We consider the story of one young woman from the state of New South Wales, in Australia, who left school early, and consider some of the factors that contributed to her decision to remove herself from compulsory education. This young woman encountered injurious speech relating to her race, gender, sexuality, size and ability. In undertaking this analysis, we draw on Foucaultian theorizing of the subject and on the related Butlerian notion of performativity. Performative acts that occur within and around schools have the power to injure, to alienate and to potentially exclude students from access to schooling. This article details how performative acts may operate as mechanisms of exclusion, obfuscating the social conventions and institutional structures that invest them with power. Our analysis of how performative acts function in school settings concludes with some suggestions of how teachers and students might think differently about the production of their own and others' existence.

Exotic grass fuel in south eastern Australia

One potentially serious impact of environmental weed invasion is an alteration to the fuel characteristics and subsequent fire regimes of an area. Considerable global evidence indicates that environmental weed invasion may produce 'new' fuel types, but there is little documented evidence of the impact of invasive exotic species on fuel characteristics and fire regimes in south-eastern Australia. This study on the impact of invasive exotic grasses in southeastern Australia has revealed major changes to fuel characteristics, particularly fuel loads.

Jurisdictional differences in contracting out GBE audits : the impact on audit pricing

This paper examines audit costs for government business enterprises in various Australian jurisdictions, focusing on whether contracting private-sector suppliers induces competitive pricing and hence lower-priced audits. One jurisdiction (New South Wales) is shown to have low levels of contracting-out. It is argued that this lowers price competition and therefore, we predict, audit costs in NSW will be higher than elsewhere in Australia. An empirical comparison shows that, controlling for other factors, NSW is statistically significantly more expensive than other Australian jurisdictions. Alternative explanations relating to variation in audit quality, jurisdiction differences and relative cost are also discussed.

The diet of a Southern Boobook Ninox novaeseelandiae in Box-ironbark country, central Victoria

The diet of a Southern Boobook Ninox novaeseelandiae in a Box-Ironbark woodland remnant in central Victoria was studied. An analysis of 42.5 pellets found invertebrates to represent 82% of the total prey items, but vertebrates, in the form of the House Mouse Mus domesticus, to represent 88% of the biomass. The proportion of spiders as prey items in the diet in this instance (43%) was significantly higher than in other studies on mainland Australia.

Cancer patient preferences for communication of prognosis in the metastatic setting

PURPOSE: To identify preferences for and predictors of prognostic information among patients with incurable metastatic cancer. PATIENTS AND METHODS: One hundred twenty-six metastatic cancer patients seeing 30 oncologists at 12 outpatient clinics in New South Wales, Australia, participated in the study. Patients were diagnosed with incurable metastatic disease within 6 weeks to 6 months of recruitment. Patients completed a survey eliciting their preferences for prognostic information, including type, quantity, mode, and timing of presentation; anxiety and depression levels; and information and involvement preferences. RESULTS: More than 95% of patients wanted information about side effects, symptoms, and treatment options. The majority wanted to know longest survival time with treatment (85%), 5-year survival rates (80%), and average survival (81%). Words and numbers were preferred over pie charts or graphs. Fifty-nine percent (59%) wanted to discuss expected survival when first diagnosed with metastatic disease. Thirty-eight percent and 44% wanted to negotiate when expected survival and dying, respectively, were discussed. Patients with higher depression scores were more likely to want to know shortest time to live without treatment (P = .047) and average survival (P = .049). Lower depression levels were significantly associated with never wanting to discuss expected survival (P = .03). Patients with an expected survival of years were more likely to want to discuss life expectancy when first diagnosed with metastases (P = .02). CONCLUSION: Most metastatic cancer patients want detailed prognostic information but prefer to negotiate the extent, format, and timing of the information they receive from their oncologists.

Income security of international students in Australia

Growth in the number of international students studying in English language countries has slowed in recent years and this development has generated extended debate amongst university managers and policy makers. In these discussions much attention has focussed on whether the slow down is to be explained by currency realignments, visa requirements, the quality of education, or the increasing competitiveness of the international education market. But what has attracted little attention is the fact that when parents and students choose in which country they will purchase a foreign education their choice is commonly influenced by the level of security that is perceived to characterise the range of options. What security means can take many forms and in this paper we focus on income security. Drawing on interview data from 9 Australian universities, we clarify the sources of international student income, the extent to which these students experience income security/insecurity, how they cope with income difficulties and/or ensure finances do not become a serious problem, and whether the nature of the information provided by governments and universities helps explain the extent of income insecurity manifest amongst international students in Australia. We argue that a significant proportion of international students studying in Australia do experience income insecurity and suggest that for both moral and economic reasons the government and the university sector should pay increased attention to this aspect of student need.
