Disability, Decoloniality, And Other-Than-Humanist Ethics In Anzaldúan Thought, Suzanne Bost

English: Faculty Publications and Other Works

Gloria Anzaldúa’s writing has been read as decolonial based on her resistance to dominant national, racial, and cultural formations. This essay turns to unpublished documents from the Gloria Anzaldúa archive that are decolonial at a more fundamental level. In autobiographical writings about her own experiences with disability, as well as doodles and figure drawings, the alternate forms of human life that Anzaldúa depicts defy the logics of identification and differentiation that underlie colonial hierarchies. Refusing to fix bodies with labels, Anzaldúa accepted mystical encounters and inter-species minglings without judgment. She experienced her own disabling conditions (including a severe hormone imbalance …

Purpose: The purpose of this study was to examine male and female adolescent’s perceptions towards their motor competence and identity development. In-depth information was also collected to understand what factors are important towards identity development during adolescence.

Method: An explanatory sequential mixed methods study was used to examine the extent motor competence influenced the health of an adolescent’s identity. …

The Difference In Being Poor In Red States Versus Blue States, Michele E. Gilman

All Faculty Scholarship

While the United States continues to recover from the 2008 Great Recession, the country still faces unprecedented inequality as increasing numbers of poor families struggle to get by with little assistance from the government. Holes in the Safety Net: Federalism and Poverty offers a grounded look at how states and the federal government provide assistance to poor people. With chapters covering everything from welfare reform to recent efforts by states to impose work requirements on Medicaid recipients, the book avoids unnecessary jargon and instead focuses on how programs operate in practice. This timely work should be read by anyone who …

The Significance Of Microbial Symbionts In Ecosystem Processes, Roxanne A. Beinart

Graduate School of Oceanography Faculty Publications

It is increasingly accepted that the microbial symbionts of eukaryotes can have profound effects on host ecology and evolution. However, the relative contribution that they make directly to ecosystem processes, like energy and nutrient flows, is less explicitly acknowledged and, in many cases, only poorly constrained. Here, I explore the idea that, in some habitats, host-associated microbes may have an outsized role in ecosystem processes relative to functionally equivalent free-living microbes due to key aspects of the physiology, ecology, and evolution of symbiotic interactions. My research quantifying symbiont metabolism has shown that microbial symbionts have the potential to make a …

A Direct Comparison Of Biplanar Videoradiography And Optical Motion Capture For Foot And Ankle Kinematics, Sarah E. Kessler, Michael J. Rainbow, Glen A. Lichtwark, Andrew G. Cresswell, Susan E. D'Andrea, Nicolai Konow, Luke A. Kelly

Kinesiology Faculty Publications

Measuring motion of the human foot presents a unique challenge due to the large number of closely packed bones with congruent articulating surfaces. Optical motion capture (OMC) and multi-segment models can be used to infer foot motion, but might be affected by soft tissue artifact (STA). Biplanar videoradiography (BVR) is a relatively new tool that allows direct, non-invasive measurement of bone motion using high-speed, dynamic x-ray images to track individual bones. It is unknown whether OMC and BVR can be used interchangeably to analyse multi-segment foot motion. Therefore, the aim of this study was to determine the agreement in kinematic …

A Proteomics Approach To Investigate Uropathogenic Escherichia Coli, Nizar Hamed E Saeedi

Other Faculty of Health Theses

Uropathogenic Escherichia coli (UPEC) is the most commonly known cause of urinary tract infection (UTI). The possession of many virulence factors and global dissemination of multi-drug resistant UPEC strains is posing a critical risk to treatment worldwide. The most virulent UPEC strains have descended from major lineages such as sequence type (ST) 131, ST38 and ST127. Strains of ST127 exhibit the highest virulence potential of most UPEC lineages, but little is known about their pathogenicity. Previous studies have reported the important role of metabolic adaptations in UPEC virulence. This study investigated the metabolic adaptations of UPEC isolates, with a focus …

Effects Of Dietary Nitrate From Vegetables On Blood Pressure In Healthy Humans, Elizabeth Ashworth

School of Health Professions Theses

Dietary nitrate is a naturally occurring component of vegetables and nitrate salts have been used for centuries as preservatives in processed meats. Up until recently, nitrate has been considered as a harmful contaminant. However, more recent research suggests that dietary nitrate supplements can reduce blood pressure (BP) and could be beneficial to cardiovascular health. This is important as 1 in 4 adults world-wide have hypertension, the largest single risk factor for cardiovascular disease. Three studies were conducted in order to assess the effects of dietary nitrate, obtained from vegetables, on BP in healthy humans. The first study evaluated the effect …

Reading Victorian Working-Class Expectations Of Fatherhood In Trials Of Paternal Negligence, Alesha Lister

SOLON Law, Crime and History (previously SOLON Crimes and Misdemeanours: Deviance and the Law in Historical Perspective)

This article examines the complex dynamics of class and gender in criminal proceedings against of men charged with feloniously causing the death of their children through neglect of their paternal duties. The intersection of ideas about respectability, masculinity and fatherhood are explored through a range of archival material generated by trials of men charged with fatally neglecting their children at the Central Criminal Court of London between 1800 and 1913. I argue that the behaviour of men accused of neglect-based homicide not only fell short of middle-class expectations of fatherhood but contravened customary expectations of fatherhood within London's working-class communities. …

Can We Distinguish Eustress From Distress In Marine Mammals? Trade-Offs In Expression Of Molecular Stress Markers And Consequences For Cell Damage And Whole-Animal Fitness Measures In Grey Seals (Halichoerus Grypus), Holly Clare Armstrong

School of Biological and Marine Sciences Theses

The ability to respond adequately to stress is crucial to an organism’s survival and fitness. Stress influences reproductive success, development, energy balance and immune responses and thus shapes life histories, population dynamics and evolutionary trajectories. Little is known about the links between cellular and whole-animal physiological stress responses in marine mammals, and their impact on tissue damage and fitness. Although stress responses may be activated under specific conditions, we need to recognise that the induction alone does not always represent a state of distress. If we are to understand the role of stress as a driver of individual health, population …

Developing Children’S Physical Literacy: How Well Prepared Are Prospective Teachers?, Judith Dinham, Paul Williams

Australian Journal of Teacher Education

While the known health impacts of sedentary lifestyles have focused attention on children’s outdoor activity, the development of their physical literacy – the physiological, social, cultural, cognitive, expressive, and psychological dimensions of their physicality – is much less in focus.

Developing children’s physical literacy is embedded in the Early Years Learning Framework and Primary curriculum: Health and Physical Education, and the performing arts subjects within The Arts. This study asks “How well prepared are pre-service teachers to implement a program that contributes to developing children’s physical literacy?”

This mixed methods study includes an environmental scan of BEd courses at 12 …

Synthesis Of Chalcone Derivatives As Ampk Activators, Duy Vu Nguyen

Chulalongkorn University Theses and Dissertations (Chula ETD)

Diabetes and diabetic nephropathy are two noticeable disorders in modern life. Chalcones are considered as a feasible candidate for these medication disorders due to the capability to activate AMPK relating to these two diseases. A series of chalcones with A-ring possessing 2'-hydroxy-, 3',4',5'-trimethoxyacetophenones or other types and B-ring decorated with mono-, di-, trisubstitution were accomplished by Claisen–Schmidt, etherification and hydrogenation reactions in almost moderate to high yield. 3-Methoxy group was found to be the best substituent for the activity in case of monosubstitution on B-ring. 3,4-Dimethoxy and 3,4-methylenedioxy groups on B-ring (63 and 65) enhanced the activity of disubstituted chalcones …

Structure And Hydration Property Of Low Molecular Weight Hyaluronic Acid By Molecular Dynamics Simulations, Panyakorn Taweechat

Chulalongkorn University Theses and Dissertations (Chula ETD)

Hyaluronic acid (HA) is a biopolymer of disaccharide with two alternate glycosidic bonds, β(1,3) and β(1,4). It has a wide-range of applications in medicine, nutrition and cosmetics. A molecular dynamics (MD) study in aqueous condition presented here unveiled conformational variability in association with the flexibility of the glycosidic linkers, which depends on the number of disaccharide units. HA chain maintains a rigid rod-like conformation with short chain lengths i.e. with 1 to 10 disaccharide units. Crossover from a rod-like to a random-coil conformation is observed with increasing the chain length i.e. with 20-50 disaccharide units. MD and DFT calculations demonstrated …
