Validation of the Fish Community Index of Estuarine Condition and development of a monitoring regime for the Swan-Canning Riverpark
No full textFish Community Indices were developed for the nearshore, shallow waters of the Swan-Canning estuary and also for its deeper, offshore waters. They integrate information on various biological variables (metrics), each of which quantifies an aspect of the structure and/or function of estuarine fish communities and responds to a wide array of stressors affecting the ecosystem. Given the well-known responses of these fauna to environmental stressors, these fish-based indices therefore provide a means to assess an important component of the ecology of the system and how it responds to changes in estuarine condition.
The present report describes a follow-up study which aimed to validate index sensitivity and robustness and to develop a monitoring regime to enable the condition of the Swan-Canning Estuary to be reliably quantified and reported into the future. The scope of this report was extended in 2012 to include a review of alternative approaches for determining estuarine condition grades/categories
Correlation of physio-chemical characteristics in the seed coat and canning quality in different dark red kidney bean (Phaseolus vulgaris l.) cultivars
No full textPlan BThe canned kidney bean (Phaseolus vulgaris L.) is one of the major consumption forms of this agricultural product. In the canning industry, seed coat splitting is considered one factor affecting the integrity of the appearance in the final product. Three different dark red kidney bean cultivars (85, 453 and Nickols) grown in the Wisconsin area were studied in this research. The physiochemical properties in this study included moisture content, the seed coat to whole seed weight ratio, the weight per seed, ash, mineral (sodium, calcium, iron, potassium and magnesium) and total crude protein content in the seed coat. The correlations of these properties with the seed coat splits were investigated. In the canned product, highly significant differences (P<0.01) in percentage of split seed coat were found among the three cultivars studied. Canned cv. 85 had significantly fewer seed coat splits than the other two cultivars. Cv. 85 was significantly higher in moisture content, as well as ash, sodium, calcium and iron content in the seed coat. The seed coat of cv. 453 was significantly higher in magnesium, and total crude protein. Cv. Nickols was found to be significantly higher in the weight per bean and seed coat splits after the canning process. Significant negative correlations were found between the percentage of seed coat splits, sodium (r = -0.89, p< 0.01), calcium (r = -0.74, P< 0.01) and iron content (r = -0.79, P< 0.05) in the seed coat. A positive correlation was found between sodium content and calcium content (r = 0.69, P< 0.05) in the seed coat. Increased calcium content in the seed coat was accompanied with increased sodium content. A significant positive relationship (r = 0.901, P< 0.01) was found between seed weight and the percentage of seed coat splits. This research suggested that several physiochemical factors of the seed coat, including weight per seed, sodium, calcium, and iron content, might play important roles in the integrity of the seed coat during the thermal processing
ECONOMIC INSTRUMENTS FOR NONPOINT SOURCE WATER POLLUTION: OPTIONS FOR THE SWAN-CANNING RIVER SYSTEM
No full textThe management of nonpoint source water pollution presents an immense challenge to economists and policy makers alike. A complex array of physical, economic, political and institutional barriers lie between theoretically appealing textbook prescriptions and their transition into successful real-world solutions. Underlying beliefs about property rights, interest group politics and the transaction costs associated with designing and implementing successful measures have all played a particularly critical role. Building on the theoretical literature and the lessons provided by the practical use of economic instruments for nonpoint source water pollution management around the world, this paper considers these issues in the context of the Swan-Canning river system in Perth. Four innovative economic instruments for the management of nonpoint source nutrient pollution in that system are discussed: auctioned best management practice payments; best management practice incentive charges; an urban nonpoint source emissions offset bank; and a catchment based licensing/trading program.Environmental Economics and Policy, Land Economics/Use,
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)

Disability and Residence Abroad
No full textThis article provides an introduction to ways of ensuring that disabled students are not denied the opportunity to participate in Residence Aboard and are not disadvantaged in the assessment of Residence Abroad. This is an important contribution to institutions' adherence to the requirements of the Disability Discrimination Act (DDA) Part IV. The fact that Residence Abroad takes place outside the UK does not absolve UK institutions of their duty of care and other legal obligations towards disabled students. Disabled students and potential students in the UK consequently have legal rights that are not affected simply because part of the course takes places outside the geographical boundaries of the UK

Placing Quebec nationalisms: constructing English identities in Quebec's Eastern Townships
No full textMost studies of nationalism in Quebec have tended to focus on national questions such as sovereignty, language laws and anglophone-francophone conflicts. The examination of national identities on an everyday level is neglected and minority and regional specificities are rarely considered. This article examines the construction of anglophone identities in the mainly rural Eastern Townships region of Quebec
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
