Open access self-archiving: An author study
No full textThis, our second author international, cross-disciplinary study on open access had 1296 respondents. Its focus was on self-archiving. Almost half (49%) of the respondent population have self-archived at least one article during the last three years. Use of institutional repositories for this purpose has doubled and usage has increased by almost 60% for subject-based repositories. Self-archiving activity is greatest amongst those who publish the largest number of papers. There is still a substantial proportion of authors unaware of the possibility of providing open access to their work by self-archiving. Of the authors who have not yet self-archived any articles, 71% remain unaware of the option. With 49% of the author population having self-archived in some way, this means that 36% of the total author population (71% of the remaining 51%), has not yet been appraised of this way of providing open access. Authors have frequently expressed reluctance to self-archive because of the perceived time required and possible technical difficulties in carrying out this activity, yet findings here show that only 20% of authors found some degree of difficulty with the first act of depositing an article in a repository, and that this dropped to 9% for subsequent deposits. Another author worry is about infringing agreed copyright agreements with publishers, yet only 10% of authors currently know of the SHERPA/RoMEO list of publisher permissions policies with respect to self-archiving, where clear guidance as to what a publisher permits is provided. Where it is not known if permission is required, however, authors are not seeking it and are self-archiving without it. Communicating their results to peers remains the primary reason for scholars publishing their work; in other words,
researchers publish to have an impact on their field. The vast majority of authors (81%) would willingly comply with a mandate from their employer or research funder to deposit copies of their articles in an institutional or subject-based repository. A further 13% would comply reluctantly; 5% would not comply with such a mandate

In a separate exercise we asked the American Physical Society (APS) and the Institute of Physics Publishing Ltd (IOPP) what their experiences have been over the 14 years that arXiv has been in existence. How many subscriptions have been lost as a result of arXiv? Both societies said they could not identify any losses of subscriptions for this reason and that they do not view arXiv as a threat to their business (rather the opposite -- this in fact the APS helped establish an arXiv mirror site at the Brookhaven National Laboratory)
Trevor Swan And The Neoclassical Growth Model
No full textTrevor Swan independently developed the neoclassical growth model. Swan (1956) was published ten months later than Solow (1956), but included a more complete analysis of technical progress, which Solow treated separately in Solow (1957). Reference is sometimes made to the "Solow-Swan growth model", but more commonly reference is made only to the "Solow growth model". This paper examines the history of Swan’s development of the growth model, the similarities and differences between the approaches of Swan and Solow and the reasons why Swan's contribution has been overshadowed. We draw on unpublished work to show that in 1950, Swan was working on a growth model in a verbal format. In 1956, Swan published only a simplified version of his model based on a Cobb-Douglas production function, but Swan's original model (circulated July 1956 and published posthumously in 2002) was much more general. Swan's reluctance to publish was consistent with his perhaps counterproductive modesty and perfectionism. His well known paper, "Longer run problems of the Balance of Payments" was circulated in 1955, eight years before publication in 1963. His pioneering work in 1945, developing the first macroeconomic model of the Australian economy, was published posthumously in 1989.
G. K. Chesterton Portrait
No full textThis item is an oil portrait of the British author G. K. Chesterton (1874–1936). It was painted by the Irish artist Edwin Swan. The portrait measures approximately 44.5 by 34 inches. This portrait is based on a black-and-white photograph of Chesterton taken in 1935 by the British photographer Howard Coster (1885-1959). This is a posthumous portrait, painted after Chesterton’s death in 1936.
Edwin Swan was born in Ballyragget, Ireland, and studied at the Academie Julian in Paris. This portrait of Chesterton was once exhibited at the Royal Academy in 1940.https://collected.jcu.edu/chestertonimages/1000/thumbnail.jp

Toxicant exposure, population genetics, and trophic associations of bottlenose dolphins (Tursiops aduncus) in the Swan River
No full textAlthough Indo-Pacific bottlenose dolphins (Tursiops aduncus) are a valued component of the Swan-Canning Estuary and the Swan Canning Riverpark, little is known about the health and ecology of the small community of dolphins inhabiting the estuary.
To improve the scientific basis for management, we examined the population genetics, trophic associations, and contaminant exposure of dolphins within the estuary. This Swan Canning Research Innovation Program (SCRIP) study had the following objectives: (1) detail contaminant concentrations in dolphins (as a baseline for future monitoring); (2) provide a preliminary assessment of health risk posed by contaminants to dolphins; (3) examine trophic pathway associations for Swan River bottlenose dolphin community; (4) use genetic information to examine whether bottlenose dolphins from the Swan-Canning Estuary and adjacent waters (Cockburn Sound) represent one homogenous population or (alternatively) if fine-scale population structuring occurs; and (5) put project findings into the perspective of system ecology and management implications.
Tissue samples for this study were obtained through remote biopsy sampling of free-ranging dolphins and the collection of tissues during post-mortem examinations under permits and licences from the WA Department of Environment and Conservation and the Murdoch University Animal Ethics Committee
Essayist and poet Alison Swan reads from her works and answers questions from audience at the Michigan Writers Series
No full textGreat Lakes writer and poet Alison Swan reads from her essay "Fresh water" and other of her works about love, hunting, and the natural world in a time of suburban sprawl, at an event held at the Michigan State University Main Library. Swan also reminisces about her time at MSU, the influence of MSU Distinguished Professor Diane Wakoski on her life and work, and describes her own writing as "an attempt to write a picture". She answers a question from the audience about submitting her first work for publication while still a student of Professor Wakoski. Swan is introduced by Librarian Peter Berg for the Michigan State University Libraries' Michigan Writers Series
Development of biotic indices for establishing and monitoring ecosystem health of the Swan-Canning Estuary
No full textThe Swan-Canning Estuary is highly valued for its ecological, recreational, commercial and indigenous importance (e.g. Seddon 1972, Swan River Trust 2008, 2009). It supports a diverse range of fish species (several of which complete their life cycles in the system and/or are recreationally or commercially important, e.g. Loneragan et al. 1989, Kanadjembo et al. 2001, Hoeksema and Potter 2006), migratory and resident waterbirds (Bamford et al. 2003), submerged and fringing vegetation (e.g. Hillman et al. 1995, Astill and Lavery 2001, McMahon 2001) and a dolphin population (Lo 2009).
The Swan-Canning Estuary and its large (ca 125 000 km2) catchment have been subjected to substantial anthropogenic change since European settlement in the early to mid 1800s, and the system is now classified as highly modified (Commonwealth of Australia 2002). These artificial modifications, combined with the ongoing effects of local population growth and climate change, continue to have a wide range of implications for the water quality of this system. For example, reduced river flow due to damming or diversion of the major tributaries and the effects of climate change, increased tidal exchange through widening and deepening of the estuary mouth and extensive clearing of catchment vegetation, have all contributed to rising salinity throughout this system (Hamilton et al. 2001, Thomson et al. 2001, Chan et al. 2002, CSIRO 2009). Changes in the volumes of marine vs riverine flow have also exacerbated the stratification of salinity and dissolved oxygen concentration within the water column, particularly in the upper estuarine reaches where bottom waters become hypoxic during drier periods of the year (Hamilton et al. 2001, Thomson et al. 2001, http://www.swanrivertrust.wa.gov.au/science/river/Content/plots.aspx). This lack of dissolved oxygen has become so extensive that remedial oxygenation of both the Swan and Canning rivers is now undertaken mechanically (http://www.swanrivertrust.wa.gov.au/ science/river/content/oxygenation.aspx). Widespread land clearing, shoreline modification and the growth of surrounding urban and agricultural activity have also resulted in increased surface runoff from the catchment, and thus also of the sediment, nutrient and pollutant loads entering the estuary. These loadings have also risen due to the vast network of drains servicing residential, farming and industrial areas that discharge into the system, and their impacts are further compounded by the reduced flushing of the estuary due to diminishing rainfall (Jakowyna et al. 2000, Swan River Trust 2003, 2009, Foulsham 2009). The system, and particularly its upper reaches, is now considered to be eutrophic to hypereutrophic (Swan River Trust 2009), and the levels of various non-nutrient contaminants in the sediment exceed ANZECC and ARMCANZ Interim Sediment Quality Guideline Trigger Values at several locations throughout the estuary (Nice 2009)
