Women's Rights In The Health Care System: Caesarean Delivery On Maternal Request, Ann-Claire Larsen

Research outputs 2014 to 2021

This article explores a systems-theoretical question on the resonance capacity of medicine and law that has enabled a recent obstetric change. Insights from autopoietic theory guide my analysis of these subsystems' preconditions or self-referencing processes supporting obstetrics to take up pregnant women's requests for caesarean sections for social reasons. Previously, obstetricians performed caesarean sections on medical grounds only. That change became possible: it resonated with obstetrics, despite limitations imposed on obstetrics and law by these subsystems' unique codes and programs, and in light of law's self-determining individual. This article argues that although the change represents a victory for women's human …

Laser Light Interaction And Their Influence On Dna And Cell Under In Vitro Conditions, Ruwaidah Abdulameer Mussttaf

School of Engineering, Computing and Mathematics Theses

Laser photobiomodulation (PBM) or low-level laser therapy (LLLT) is a form of phototherapy recognized worldwide for its expansive use in medicine. PBM/LLLT has the ability to enhance enzymatic activity and mitochondrial transmembrane potential that increase the availability of energy and the signal transduction, which promotes cell proliferation. This study primarily investigates the appropriateness of a range of treatment parameters, including light wavelength, irradiance (doses) and exposure time of PBM/LLLT in proliferation of cultured human monocytic leukaemia cell line THP-1(Tamm-Horsfall Protein 1), as well as DNA under in vitro conditions. A secondary objective was to exploit the beneficial effect of PBM/LLLT …

Managing Seagrass Resilience Under Cumulative Dredging Affecting Light: Predicting Risk Using Dynamic Bayesian Networks, Paul Pao-Yen Wu, Kathryn Mcmahon, Michael A. Rasheed, Gary A. Kendrick, Paul H. York, Kathryn Chartrand, M. Julian Carey, Kerrie Mengerson

Research Datasets

Coastal development is contributing to ongoing declines of ecosystems globally. Consequently, understanding the risks posed to these systems, and how they respond to successive disturbances, is paramount for their improved management. We study the cumulative impacts of maintenance dredging on seagrass ecosystems as a canonical example. Maintenance dredging causes disturbances lasting weeks to months, often repeated at yearly intervals. We present a risk-based modelling framework for time varying complex systems centred around a dynamic Bayesian network (DBN). Our approach estimates the impact of a hazard on a system's response in terms of resistance, recovery and persistence, commonly used to characterise …

Effects Of Small-Scale, Shading-Induced Seagrass Loss On Blue Carbon Storage: Implications For Management Of Degraded Seagrass Ecosystems, Stacey M. Trevathan-Tackett, Caitlin Wessel, Just Cebrian, Peter J. Ralph, Pere Masque´, Peter I. Macreadie

Research Datasets

1. Seagrass meadows are important global ‘blue carbon’ sinks. Despite a 30% loss of seagrasses globally during the last century, there is limited empirical research investigating the effects of disturbance and loss of seagrass on blue carbon stocks.

2. In this study, we hypothesised that seagrass loss would reduce blue carbon stocks. Using shading cloth, we simulated small-scale die-offs of two subtropical seagrass species, Halodule wrightii and Thalassia testudinum, in a dynamic northern Gulf of Mexico lagoon. The change in quantity and quality of sediment organic matter and organic carbon were compared among kill, control and bare plots before the …

Latitudinal Variation In Seagrass Herbivory: Global Patterns And Explanatory Mechanisms, Adriana Vergés, Christopher Doropoulos, Robert Czarnik, Kathryn Mcmahon, Nil Llonch, Alistair G. B. Poore

Research Datasets

Aim: The aim was to quantify latitudinal patterns in seagrass–herbivore interactions in the context of a warming climate.

Location: We carried out a global meta‐analysis combined with a field experiment across 1,700 km and 12° of latitude in Western Australia.

Time period: 1984–2014. Major taxa studied: Seagrasses.

Methods: We first synthesized the global literature on herbivore exclusion experiments in seagrasses to test whether differences in herbivore impacts are related to latitude and sea surface temperature. We then quantified leaf production and consumption rates in the field at nine meadows of the seagrass Amphibolis antarctica across 1,700 km, from tropical to …

Optimal Soil Carbon Sampling Designs To Achieve Cost-Effectiveness: A Case Study In Blue Carbon Ecosystems, Mary A. Young, Peter I. Macreadie, Clare Duncan, Paul E. Carnell, Emily Nicholson, Oscar Serrano, Carlos M. Duarte, Glenn Shiell, Jeff Baldock, Daniel Ierodiaconou

Research Datasets

Researchers are increasingly studying carbon (C) storage by natural ecosystems for climate mitigation, including coastal ‘blue carbon’ ecosystems. Unfortunately, little guidance on how to achieve robust, cost-effective estimates of blue C stocks to inform inventories exists. We use existing data (492 cores) to develop recommendations on the sampling effort required to achieve robust estimates of blue C. Using a broad-scale, spatially explicit dataset from Victoria, Australia, we applied multiple spatial methods to provide guidelines for reducing variability in estimates of soil C stocks over large areas. With a separate dataset collected across Australia, we evaluated how many samples are needed …

Evaluating The Recovery Of Dna From Adhesive Tape After Exposure To Heat And Humidity: Assessing The Degradation Index And Str Profile, Emily Davis

Graduate Theses, Dissertations, and Problem Reports (ETD)

It is not uncommon for forensic DNA samples to be degraded or of low quantity; these types of samples can pose challenges throughout analysis and an informative STR profile is not guaranteed. DNA analysis is also very expensive and timely; therefore, it is necessary to understand where to sample a piece of evidence to obtain the best quality and quantity of DNA from the substrate, especially in the case of trace DNA samples which may be difficult to detect. It is also necessary to know when to proceed with analysis given the quality of the sample. The aim of this …

Dissensual Women: Modernist Women Writers, The Senses, And Technology, Allyson Demaagd

Graduate Theses, Dissertations, and Problem Reports (ETD)

My project, Dissensual Women: Modernist Women Writers, the Senses, and Technology, analyzes depictions of the senses and technology in modernist women's writing. I argue that modernist women writers challenge traditional sensory hierarchies that value the so-called masculine senses of sight and sound and denigrate the so-called feminine senses of smell, taste, and touch. H.D., Mina Loy, Virginia Woolf, and Elizabeth Bowen revalue the feminine senses, challenge sensory elitism, and advocate for an inclusive sensorium, one that features the perceptions and experiences of women, queer women, the lower classes, the nonhuman, and the differently abled. They wage their dissent through experimentation …

An Exploration Of Diversity And Inclusion In Introductory Physics, Rachel J. Henderson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Diversity and inclusion has been a concern for the physics community for nearly 50 years. Despite significant efforts including the American Physical Society (APS) Conferences for Undergraduate Women in Physics (CUWiP) and the APS Bridge Program, women, African Americans, and Hispanics continue to be substantially underrepresented in the physics profession. Similar efforts within the field of engineering, whose students make up the majority of students in the introductory calculus-based physics courses, have also met with limited success. With the introduction of research-based instruments such as the Force Concept Inventory (FCI), the Force and Motion Conceptual Evaluation (FMCE), and the Conceptual …

From The Cover: 7,8-Dihydroxyflavone Rescues Lead-Induced Impairment Of Vesicular Release: A Novel Therapeutic Approach For Lead Intoxicated Children, Xiao-Lei Zhang, Jennifer L. Mcglothan, Omid Miry, Kirstie H. Stansfield, Meredith K. Loth, Patric K. Stanton, Tomas R. Guilarte

NYMC Faculty Publications

Childhood lead (Pb2+) intoxication is a public health problem of global proportion. Lead exposure during development produces multiple effects on the central nervous system including impaired synapse formation, altered synaptic plasticity, and learning deficits. In primary hippocampal neurons in culture and hippocampal slices, Pb2+ exposure inhibits vesicular release and reduces the number of fast-releasing sites, an effect associated with Pb2+ inhibition of NMDA receptor-mediated trans-synaptic Brain-Derived Neurotrophic Factor (BDNF) signaling. The objective of this study was to determine if activation of TrkB, the cognate receptor for BDNF, would rescue Pb2+-induced impairments of vesicular release. Rats were chronically exposed to Pb2+ …

Rights Skepticism And Majority Rule At The Birth Of The Modern First Amendment, Vincent A. Blasi

Faculty Scholarship

Learned Hand, Oliver Wendell Holmes, and Louis Brandeis all had the same problem. They were troubled — Holmes less than the others and later, but eventually — by the widespread and mean-spirited persecution of dissenters they observed as the United States entered World War I and then reacted to the Bolshevik Revolution. Today, most persons so troubled would think that constitutional rights, and particularly the freedom of speech, exist for the very purpose of countermanding zealous political majorities that deny or neglect the claims of dissenters. But Hand, Holmes, and Brandeis, each by his own distinctive path, came to the …

Minimally Actuated Walking: Identifying Core Challenges To Economical Legged Locomotion Reveals Novel Solutions, Ryan T. Schroeder, John Ea Bertram

Research outputs 2014 to 2021

Terrestrial organisms adept at locomotion employ strut-like legs for economical and robust movement across the substrate. Although it is relatively easy to observe and analyze details of the solutions these organic systems have arrived at, it is not as easy to identify the problems these movement strategies have solved. As such, it is useful to investigate fundamental challenges that effective legged locomotion overcomes in order to understand why the mechanisms employed by biological systems provide viable solutions to these challenges. Such insight can inform the design and development of legged robots that may eventually match or exceed animal performance. In …

Associative Learning In Biochemical Networks, Yasmin S. Sepulveda

REU Final Reports

Emerging evidence suggests that biochemical networks can be modeled by exploiting their ability to learn through associative learning. This type of learning in biomolecular structures gives it a the advantage to be able to be computationally model, and condition. Associative learning in biochemical networks is a developing area of study that once understood, can further develop diagnostic applications, and be used as tools for data analysis. Although it is a open ended project the motive of this research was to find the the best method of association learning being used in current work. After reading current work three associative learning …

Deciphering The Rules Of Cell-To-Cell Coupling By Molecular Modeling And Simulation, Linda D. Lee

REU Final Reports

Intercellular communication is vital for quick adjustments and maintenance for cell function and development. Gap junctions are membranes channel proteins that enable this direct communication between adjacent cells throughout the body. The compatibility of connexins (Cx), which make up a gap junction, determines whether a gap junction can form. Though many studies show which connexins are compatible, the molecular basis is not known (Bai & Wang, 2014). Through computational modeling, we identify the residues that energetically contribute most favorably at the docking interface of homotypic and heterotypic combinations of Cx43, Cx46, and Cx50 gap junctions. However, due to instability of …

The Distribution And Trophic Ecology Of Golden Ghost Crabs (Ocypode Convexa), Caitlin Rae

Theses: Doctorates and Masters

Sandy beaches make up approximately three-quarters of the world’s shorelines. They are important ecosystems, hosting abundant invertebrate macrofaunal communities that provide food resource for vertebrate predators such as shorebirds, seabirds, marine mammals and fish. Although possessing a terrestrial appearance, food input on sandy beaches is derived predominantly from the sea. Such food input includes detrital matter, mostly in the form of wrack, and has the potential to support a great diversity of species, as well as stabilising energy fluxes and dynamics of consumer populations. The movement of detritus, along with other vectors such as organisms and nutrients, across ecosystem boundaries …

Comparative Pairs Judgements For High-Stakes Practical Assessments, Hendrati Nastiti

Theses: Doctorates and Masters

Assessment of practical tasks, as opposed to that of theoretical tasks, has been considered to be problematic, mainly because it is usually resource intensive and the scoring is subjective. Most practical tasks need to be assessed on site or involve products that need to be collected, stored, or transported. Moreover, because practical tasks are generally open-ended, and therefore subjective, there is concern over the reliability of the scores. In high-stakes assessment, these problems are even more challenging. There is a need for an assessment method that could overcome these problems. In this study, such a method that will be referred …

Breathing New Life: Investigating Ways To Improve The Mental Health Of People Living With Chronic Obstructive Pulmonary Disease In Western Australia, Tina Phan

Theses: Doctorates and Masters

Anxiety and depression are common comorbidities in people with chronic obstructive pulmonary disease (COPD), contributing to greater morbidity and mortality in an already vulnerable population. Despite the prevalence, few recommendations exist in global management guidelines for the detection and treatment of these comorbidities, reflecting the limited literature available on effective strategies for dealing with mental health issues in COPD populations. There is promising evidence that cognitive behavioural therapy (CBT) improves mental health outcomes in people with COPD. However, investigational studies have commonly reported participants’ lack of transport, lack of time and illness as barriers to recruitment and successful completion. This …

Within-Fire Patchiness Associated With Prescribed Burning In The Northern Jarrah Forests Of Western Australia, Zigourney Nielsen

Theses: Doctorates and Masters

There is growing understanding of the importance of landscape mosaics and heterogeneity for biodiversity outcomes in Western Australia. However, there is limited information on the patchiness (spatial configuration of unburnt and burnt patches which occur at a range of spatial scales) within the perimeter of a single prescribed burn. Of particular concern is the idea that prescribed burning operations, carried out under very restricted weather and environmental conditions, can lead to structural and floristic homogenization of the area within a burn perimeter. This may be evident as reduced post-fire vegetation patchiness. Western Australian Jarrah (Eucalyptus marginata) forests are managed to …

Young People Who Fireset In Western Australia: Peer Group Influences And Impulsiveness Trump Consequences, Catherine Analise Timms

Theses: Doctorates and Masters

The paradoxical character of fire is perfectly captured by the juxtaposition between the initial ease and excitement of lighting fires, and fire’s destructive and uncontrollable nature. Australia is fire prone with its hot, dry climate, volatile vegetation and urban sprawl surrounded by bushland. Since an estimated 50% of fires lit in Australia are deliberate (Stanley & Read, 2016) the problem of intentional firesetting cannot be overstated. This thesis argues that youth firesetting requires both macro- and microlevel approaches to appreciate the complexities of the problem, and aims to identify applicable and directed responses to minimise youth firesetting. Study one analysed …
