Comparison Of Seal Oil To Tuna Oil On Plasma Lipid Levels And Blood Pressure In Hypertriglyceridaemic Subjects, Barbara J. Meyer, A E. Lane, N J. Mann

Faculty of Health and Behavioural Sciences - Papers (Archive)

As meat is a rich source of the omega-3 fatty acid docosapentaenoic acid (DPA) and Australians consume six times more meat than fish, investigation of the potential health benefit of DPA is warranted. The aims were to compare the effects of seal oil supplementation with fish oil, on measures of plasma lipids and blood pressure in hypertriglyceridaemic subjects. Forty-eight volunteers were recruited from the Wollongong community and were randomly allocated to one of three groups either receiving 1 g/day of long-chain omega-3 polyunsaturated fatty acids (LC n-3 PUFA) using one of three oils: seal oil capsules (340 mg eicosapentaenoic acid …

Borderline Personality Or Complex Posttraumatic Stress Disorder? An Update On The Controversy, Kate L. Lewis, Brin Grenyer

Faculty of Health and Behavioural Sciences - Papers (Archive)

There remains controversy surrounding the nature of the relationship between borderline personality disorder and posttraumatic stress disorder, with strong arguments that it would be more accurate and less stigmatizing for the former to be considered a trauma spectrum disorder. This article reviews the major criticisms of the DSM-IV diagnosis of borderline personality disorder that have fueled this controversy, including the absence of an etiology for the disorder, which is widely believed to be associated with early traumatic experiences. Also reviewed are recent attempts to redefine the disorder as a trauma spectrum variant based on the apparent overlap in symptomatology, rates …

Dietary Intakes Of Children With Crohn's Disease, Rachel Pons, Kylie E. Whitten, Helen Woodhead, Steven T. Leach, Daniel A. Lemberg, Andrew S. Day

Faculty of Health and Behavioural Sciences - Papers (Archive)

Approximately 25 % of individuals with Crohn's disease (CD), a life-long relapsing-remitting disease, are diagnosed during childhood and adolescence. Symptoms of CD, including abdominal pain, nausea and diarrhoea, can lead to reduced food intake, which may negatively have an impact on nutritional status during this critical period of growth and development. The aims of the present study were to assess the growth and adequacy of dietary intakes of children with CD at Sydney Children's Hospital, Randwick, and compare with healthy controls. Sixty-three subjects aged 10–16 years were recruited, including: children with active CD (n 18), children with CD in …

Developing Korean Academy Of Medical Sciences Guideline For Rating The Impairment In Mental And Behavioural Disorders; A Comparative Study Of Knpa's New Guidelines And Ama's 6th Guides, Gordon R. Davies

Faculty of Health and Behavioural Sciences - Papers (Archive)

I refer to the paper by Ryu, Hong, Jung, Hwang, Jung, Jeong, Rah and Suh (2009) (1). The assessment of psychiatric disability is difficult and fraught with methodological problems and the review by Ryu and colleagues tends to perpetuate the use of methods of assessment which have no firm evidence base as well as ignoring some significant problems with the use of the American Medical Association Guides as well as the Psychiatric Impairment Rating Scale (PIRS).

Functional Transition In The Floral Receptacle Of The Sacred Lotus (Nelumbo Nucifera): From Thermogenesis To Photosynthesis, R. E. Miller, J. R. Watling, Sharon A. Robinson

Faculty of Science - Papers (Archive)

The receptacle of the sacred lotus is the main source of heat during the thermogenic stage of floral development. Following anthesis, it enlarges, greens and becomes a fully functional photosynthetic organ. We investigated development of photosynthetic traits during this unusual functional transition. There were two distinct phases of pigment accumulation in receptacles. Lutein and photoprotective xanthophyll cycle pigments accumulated first with 64% and 95% of the maximum, respectively, present prior to anthesis. Lutein epoxide comprised 32% of total carotenoids in yellow receptacles, but declined with development. By contrast, more than 85% of maximum total chlorophyll, β-carotene and Rubisco were produced …

From Powder To Solution: Hydration Dependence Of Human Hemoglobin Dynamics Correlated To Body Temperature, A. M. Stadler, I. Digel, J. P. Embs, T. Unruh, Moeava Tehei, G. Zaccai, G. Büldt, G. M. Artmann

Faculty of Science - Papers (Archive)

A transition in hemoglobin (Hb), involving partial unfolding and aggregation, has been shown previously by various biophysical methods. The correlation between the transition temperature and body temperature for Hb from different species, suggested that it might be significant for biological function. In order to focus on such biologically relevant human Hb dynamics, we studied the protein internal picosecond motions as a response to hydration, by elastic and quasielastic neutron scattering. Rates of fast diffusive motions were found to be significantly enhanced with increasing hydration from fully hydrated powder to concentrated Hb solution. In concentrated protein solution, the data revealed that …

A Comparison Of Development Times For Protophormia Terraenovae (R-D) Reared On Different Food Substrates, J.-A. Warren, G. S. Anderson

Faculty Research, Scholarly, and Creative Activity

Experiments were conducted to determine whether a specific larval substrate impacted immature development rates. Protophormia terraenovae was raised on beef organs and compared with whole carcasses (rat), to determine if discrepancies in development times were observed. The minimum development time on beef liver was the most consistent with the rat carcass but a significant difference between all substrates was found after the third instar. These differences can be explained by the differences found between heart and muscle and the other substrates. Often length of the larvae is used to estimate insect age and so Day 2 measuring of weight, length, …

"The Natural History Of Truth: The Neurobiology Of Belief", Neil Greenberg

Faculty Publications and Other Works -- Ecology and Evolutionary Biology

The pursuit of truth is woven into the fabric of every organism*. Any estimate of how best to survive and thrive in the reality in which we are immersed requires a sense of self, of the world, and of their relationship to each other. I wish to explore the idea that this pursuit has at its heart two complementary modes of reality testing utilizing separate cerebral systems which deal, respectively with the correspondence of experience with the world and the coherence of the experience with previous experiences: “is it real” and “does it fit?” At multiple levels of the nervous …

The Role Of Landscape Connectivity In Assembling Exotic Plant Communities: A Network Analysis, Emily S. Minor, Samantha M. Tessel, Katharina A.M. Engelhardt, Todd R. Lookingbill

Geography and the Environment Faculty Publications

Landscape fragmentation and exotic species invasions are two modern-day forces that have strong and largely irreversible effects on native diversity worldwide. The spatial arrangement of habitat fragments is critical in affecting movement of individuals through a landscape, but little is known about how invasive species respond to landscape configuration relative to native species. This information is crucial for managing the global threat of invasive species spread. Using network analysis and partial Mantel tests to control for covarying environmental conditions, we show that forest plant communities in a fragmented landscape have spatial structure that is best captured by a network representation …

The Corporate Agenda For Environmental Property Rights, Sharon Beder

Faculty of Arts - Papers (Archive)

Market and property-rights based approaches to environmental problems have been heavily promoted by conservative think tanks. Consequently policies such as emissions trading, water markets, tradeable fishing quotas and conservation banking pervade environmental policy in English speaking nations. They have enabled the corporate neo-liberal agenda of deregulation, privatisation and an unconstrained market to be dressed up as an environmental virtue. This market-faith based approach is proving to be largely ineffective at protecting the environment and also inequitable.

On Race Theory And Norms, Christian Sundquist

Articles

This article has been adapted from an address given at the Albany Law Review Symposium in Spring 2009. This article discusses the judicial acceptance of DNA random match estimates, which uses DNA analysis to estimate the likelihood that a criminal defendant is the source of genetic material that is found at a crime scene. Relying on race, these tests demonstrate how such a re-inscription of race as a biological entity threatens the modern conception of race as a social construction, and how those estimates should be rejected as inadmissible on a doctrinal level under the Federal Rules of Evidence.

An Inventory And Condition Survey Of The Lower Murchison River Area, Western Australia, P Hennig

Technical Bulletins

The inventory and condition survey of the lower Murchison River area, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 2002 and 2003, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. This survey report presents …

The Tadpole Of Hypsiboas Atlanticus (Anura, Hylidae) From Northeastern Brazil, Filipe A. C. Do Nascimento, Marcelo G. De Lima, Gabriel O. Skuk, Rafael O. De Sá

Biology Faculty Publications

The tadpole of Hypsiboas atlanticus (Caramaschi & Velosa, 1996) is described from the municipality of Maceió, State of Alagoas, Brazil. At stage 36 the larvae have an overall elliptical body in lateral and dorsal views, oral disc anteroventral, spiracular tube sinistral, and labial tooth row formula 2(1,2)/3(1). The oral disc is surrounded, almost completely (anterior medial gap present) by a single row of marginal papillae. Described tadpoles of the H. punctatus species group can be differentiated by a combined disc oral features. Additional descriptions of H. punctatus (Schneider, 1799) tadpoles from populations throughout South America may be helpful in determining …

Surface Mining And Reclamation Effects On Flood Response Of Watersheds In The Central Appalachian Plateau Region, Todd R. Lookingbill, Joseph R. Ferrari, B. Mccormick, P. A. Townsend, K. N. Eshleman

Geography and the Environment Faculty Publications

Surface mining of coal and subsequent reclamation represent the dominant land use change in the central Appalachian Plateau (CAP) region of the United States. Hydrologic impacts of surface mining have been studied at the plot scale, but effects at broader scales have not been explored adequately. Broad-scale classification of reclaimed sites is difficult because standing vegetation makes them nearly indistinguishable from alternate land uses. We used a land cover data set that accurately maps surface mines for a 187-km2 watershed within the CAP. These land cover data, as well as plot-level data from within the watershed, are used with HSPF …

Altered Ecological Flows Blur Boundaries In Urbanizing Watersheds, Todd R. Lookingbill, Sujay S. Kaushal, Andrew J. Elmore, Robert Gardner, Keith N. Eshleman, Robert H. Hilderbrand, Raymond P. Morgan, Walter R. Boynton, Margaret A. Palmer, William C. Dennison

Geography and the Environment Faculty Publications

The relevance of the boundary concept to ecological processes has been recently questioned. Humans in the post-industrial era have created novel lateral transport fluxes that have not been sufficiently considered in watershed studies. We describe patterns of land-use change within the Potomac River basin and demonstrate how these changes have blurred traditional ecosystem boundaries by increasing the movement of people, materials, and energy into and within the basin. We argue that this expansion of ecological commerce requires new science, monitoring, and management strategies focused on large rivers and suggest that traditional geopolitical and economic boundaries for environmental decision making be …

A Serological Survey Of Infectious Disease In Yellowstone National Park’S Canid Community, Emily S. Almberg, L. David Mech, Douglas W. Smith, Jennifer W. Sheldon, Robert L. Crabtree

USGS Northern Prairie Wildlife Research Center

Background: Gray wolves (Canis lupus) were reintroduced into Yellowstone National Park (YNP) after a .70 year absence, and as part of recovery efforts, the population has been closely monitored. In 1999 and 2005, pup survival was significantly reduced, suggestive of disease outbreaks.

Methodology/Principal Findings: We analyzed sympatric wolf, coyote (Canis latrans), and red fox (Vulpes vulpes) serologic data from YNP, spanning 1991–2007, to identify long-term patterns of pathogen exposure, identify associated risk factors, and examine evidence for disease-induced mortality among wolves for which there were survival data. We found high, constant exposure to canine …

Animal Helminths In Human Archaeological Remains: A Review Of Zoonoses In The Past, Luciana Sianto, Marcia Chame, Cassius S. P. Silva, Marcelo L. C. Gonçalves, Karl Reinhard, Martín Horacio Fugassa, Adauto Araújo

Karl Reinhard Publications

The authors present a review of records of intestinal parasitic helminths from animals in human archaeological remains, reported since the emergence of paleopathological studies. The objective was to relate paleoparasitological findings to geographic, biotic, and abiotic factors from the environment in which the prehistoric populations lived, and understand some aspects related to the process of human dispersion and biological and cultural evolution. Modification of eating habits and the incorporation of new cultural practices are analyzed from the perspective of zoonoses from prehistory to the present day, especially in Brazilian indigenous populations. Three tables identifying the helminths, their natural hosts, dates, …

The Neuroscientific Study Of The Self: Methodological And Theoretical Challenges, Cynthia J. Najdowski, Samuel E. Winer

Psychology Faculty Scholarship

Neuroscientific research methods, such as brain imaging techniques, have increasingly been applied to social cognitive research efforts and, in particular, to the study of the self. In this essay we discuss the ability of such research to shed light on the emergent, dynamic psychological phenomenon of self. Although neuroscientific tools can be useful for gaining general knowledge about associated underlying structures, a careful consideration of the methodological and theoretical issues discussed herein is necessary to avoid simplifying or reifying the self.

Seeing Shifts: Ecologists' Lived Experiences Of Climate Change In Mountains Of The American West, Kimberly Ford Langmaid

Antioch University Dissertations & Theses

This study explores the lived experiences of field ecologists who research the effects of global climate change on mountain species and ecosystems in the American West. The purpose is to generate narrative descriptions of ecologists’ experiences in order to communicate about both the scientific ecology and human ecology of climate change. Twenty prominent field ecologists participated in this study. Interviews with ecologists were transcribed and analyzed using a hermeneutic phenomenological methodology. Eight experiential themes emerged through the process of data analysis, and these themes provide the structure for presenting narratives of ecologists’ experiences. The eight themes are: thinking ecologically, the …

Farmers And Nature Conservation: What Is Known About Attitudes, Context Factors And Actions Affecting Conservation?, Johan Ahnström, Jenny Höckert, Hanna L. Bergea, Charles A. Francis, Peter Skelton, Lars Hallgren

Department of Agronomy and Horticulture: Faculty Publications

Farmers’ attitudes towards viability of specific conservation practices or actions strongly impact their decisions on adoption and change. This review of ‘attitude’ information reveals a wide range of perceptions about what conservation means and what the impacts of adoption will mean in economic and environmental terms. Farmers operate in a tight financial situation, and in parts of the world they are highly dependent on government subsidies, and cannot afford to risk losing that support. Use of conservation practices is most effective when these are understood in the context of the individual farm, and decisions are rooted in land and resource …
