Sofa-Surfing: The Cartographies Of Young People Utilising Host-Dependent Shelter., Kieran Green

School of Geography, Earth and Environmental Sciences Theses

In 2016, 35% of UK young people (16-25 years) reported having sofa-surfed in the past. Past research highlights that spaces where people sofa-surfing stay are often tenuous, short-lived and worsen over time, reducing mental health, educational attainment, and the ability to find work (McLoughlin, 2013; Albanese et al., 2018). However, a study has not elucidated how young people’s preferences, identities, experiences, and access to support create highly varied sofa-surfing geographies and outcomes. This study examined young people's different geographical experiences and outcomes of sofa-surfing. Specifically, I outline key sofa-surfing experiences centred on uses of space, mobility, and identity (cartographies) and …

Success Factors Facilitating Care During Escalation (The Suffice Study), Jody Ede

School of Nursing and Midwifery Theses

BACKGROUND: In the United Kingdom, there continues to be preventable National Health Service (NHS) patient deaths. Contributory factors include inadequate recognition of deterioration, poor monitoring, or delayed escalation to a higher level of care. Strategies to improve care escalation, such as vital sign scoring systems and specialist teams who manage deterioration events, have shown variable impact on patient mortality. The need for greater care improvements has consistently been identified in NHS care reviews as well as patient stories. Furthermore, current research informing escalation improvements predominantly comes from examining failure to rescue events, neglecting what can be learned from rescue or …

An Exploration Of Preconception Care For People With Health Conditions Using Realist Methodology: What Works, For Whom, And In What Circumstances?, Heather Hopper

School of Nursing and Midwifery Theses

Background: People living with pre-existing physical or mental health conditions are over-represented in audits and confidential enquiries regarding maternal morbidity and mortality and thus often advised to stabilise or optimise their health prior to becoming pregnant. Preconception care may include medication or behaviour change, which can be effective but not always accessed by those who need it, and there is a lack of evidence demonstrating how this can be achieved. The aim of this study was therefore to explore what form of preconception care for people living with health conditions works, for whom, how do these approaches work, and in …

Navigating A Complex Transition: From Qualifying As A Nurse To Becoming A Confident Practitioner., Rachel Pascoe

School of Nursing and Midwifery Theses

This thesis explores the complexities of transition to professional practice of newly qualified nurses following an undergraduate professional preparation programme. Transition to professional practice from student to qualified nurse and then to confident practitioner has been explored since the late 1960s and is recognised as a complex and multi-faceted issue for the newly qualified nurses. They can feel unprepared for clinical practice and for the organisational demands who require competent and confident personnel to join the workforce. Adopting a social constructionist approach, this study utilises a combination of diaries and interviews to gain a deeper understanding of the experiences and …

Development And Validation Of A Patient-Reported Experience Measure For Older Adults Attending The Emergency Department: The Prem-Ed 65 Study, Blair Graham

School of Nursing and Midwifery Theses

Emergency Department (ED) care traditionally focuses on resolving single-organ pathology, emphasising rapid patient flow. As such, ED care may fall short of addressing the holistic needs of older adults, where atypical and complex presentations exacerbated by frailty, comorbidity, polypharmacy, and sensory deficits are much more prevalent than in the general population. Older adults are particularly vulnerable to the effects of ED crowding and prolonged length of ED stay and suffer increased in-hospital mortality as a result.Patient experience is a central determinant of quality of care and is positively associated with improved outcomes for acute conditions, including pneumonia, asthma, and acute …

The Reconstruction Of Climate In Beringia By Analysis Of Glycerol Dialkyl Glycerol Tetraether (Gdgt) Distributions Using High Performance Liquid Chromatography – Mass Spectrometry (Hplc-Ms)., Lauren Beth Pankhurst

School of Geography, Earth and Environmental Sciences Theses

The reconstruction of past environments, including temperatures, aids in the production of climate models which predict how the Earth will respond to future climatic changes that are occurring at an accelerated rate, due to global warming. High-latitude seas, including the Bering Sea, are sensitive to changes in global climate, across both glacial and interglacial timescales. Membrane lipids synthesised by archaea and bacteria are retained within the sediment and when extracted give evidence to the environmental conditions present during the organism’s lifetime. The membrane lipids are structured in a way that is chemically favourable to their environment, and calibrations derived in …

Using Remote Sensing To Track Complex Sinuous Ripple Migration On A Barchan Dune In Herschel Crater, Mars, Elizabeth Visick

School of Geography, Earth and Environmental Sciences Theses

Dunes on Mars are known to migrate, in particular ripples have also been found to migrate. This is known to have occurred in eastern, western and southern Herschel Crater, but it was not known if this was true for Central Herschel Crater. Central Herschel Crater is of particular interest as the dunes found there were deemed indurated. However, since the release of HiRISE (2023) satellite images it is clear that these dunes are in fact very much the opposite. These dunes were actively migrating and presented some unique superimposed ripples. With this, we set out to measure the migration of …

Volcanic Debris Avalanche Propagation And Emplacement Mechanisms: Sedimentological Field Evidence And Bidisperse Granular Flow Experiments, Symeon Makris

School of Geography, Earth and Environmental Sciences Theses

Volcanic debris avalanches mobilise large volumes and achieve long runouts with high destructive potential. Although many theories have been proposed regarding the mechanisms that enable their long runouts, the processes remain unknown. Theoretical and numerical models are unable to account for their long runout while being consistent with deposit observations. Therefore, evaluation of their dynamics in reference to deposit structure and sedimentology is fundamental for constraining such models. This thesis explores volcanic debris avalanche propagation dynamics and evaluates potential factors contributing to their long runouts. A systematic comparison of volcanic debris avalanches and lahars allows the evaluation of water as …

Resilience Thinking And The Influence Of Street-Level Bureaucrats On The Implementation Of Eu Environmental Policies In Overseas Territories: Lessons From Gibraltar., Jaime Sanchez-Garcia

School of Geography, Earth and Environmental Sciences Theses

The policy implementation literature has provided important insights on how policy formulation processes affect the achievement of policy goals and how street-level bureaucrats (SLBs) involved in policy implementation utilise coping mechanisms to overcome shortages in resources, expertise and other local constraints. However, it has struggled to provide a systematic analysis of how contextual factors influence the work of SLBs or the implications of their coping mechanisms for the functioning of implementation systems, particularly in smaller countries and non-states territories, where mismatches between policy requirements and resources are more acute. This thesis addresses these knowledge gaps by examining the implementation of …

Andean Sediment Response To Natural And Anthropogenic Changes At The Catchment Scale, Jessica Kitch

School of Geography, Earth and Environmental Sciences Theses

Changing climate and population growth poses a challenge for the water, food and energy security nexus, particularly in glacier-fed mountainous catchments. Soil erosion, driven by both natural and anthropogenic activities, further exacerbates the challenge for resource security. Soil erosion is contributing to increased levels of sediment in river systems threatening crucial river functions, including crop irrigation, drinking water, and hydroelectricity. Past studies in the Andes regarding soil erosion have indicated that human activities have accelerated soil erosion and rates often exceed natural soil production. To date, the majority of Andean studies have primarily focused on larger eastern catchments, with fewer …

Technology Impacts, Justice, Place, And Worldviews: An Integrated Framework For Understanding Perceptions Of And Attitudes Towards Shale-Gas Fracking In English Host Communities, Kechagia Magdalini

School of Geography, Earth and Environmental Sciences Theses

Despite growing national opposition, local resistance, and moratoriums in Scotland and Wales, successive UK governments have supported the use of fracking to exploit oil and gas from shale formations in England in response to declining North Sea reserves and concerns about geopolitical instabilities affecting energy security. Although scholars have examined technological, justice, and socio-psychological drivers of social attitudes to fracking in order to challenge ‘Not-In-My-Back-Yard’ explanations of perceptions and attitudes, existing studies have rarely examined these factors in an integrated way. The aim of this research is to investigate whether and how an integrated approach, combining insights from the factors …

Association Of Pulmonary Artery Pressures With Mortality In Adults With Reduced Left Ventricular Ejection Fraction, Seshika Ratwatte, Simon Stewart, Geoff Strange, David Playford, David Celermajer

IHR Papers and Journal Articles

Background

The independent effect of pulmonary hypertension (PHT) severity on mortality in those with reduced left ventricular ejection fraction (LVEF) is not well known.

Objectives

The authors aimed to examine the prognostic impact of increasingly elevated pulmonary pressures in a large clinical cohort of adults with reduced LVEF.

Methods

The authors analyzed data from the National Echocardiography Database of Australia, a large clinical registry linking routine echocardiographic investigations to mortality. In 23,675 adults with a recorded tricuspid regurgitation peak velocity (TRV) and reduced LVEF (<50%), the authors evaluated the relationship between conventional thresholds of increasing risk of PHT and mortality during median follow-up of 2.9 years (Q1-Q3: 1.0-5.4 years).

Results

Mean age was 70 ± 15 years, and 7,498 (31.7%) individuals were female. Overall, …

Epigenetic Regulation Of Inflammatory Pathways In Alcohol Related Hepatitis, Huey Kuan Tan

Peninsula Medical School Theses

Background: Alcohol-related liver disease (ArLD) contributes to approximately 1% of deaths worldwide and impacts on both economy and healthcare system. Alcohol related hepatitis (AH) - phenomenon of ArLD which is characterised by overactive inflammation is associated with 30% mortality rate at 90 days. Glucocorticoids (GC) are commonly used to treat AH. However, more than 1 in 3 patients fail to respond to GC therapy. Within the GC responders, the efficacy is variable due to individual glucocorticoid resistance. Improving our comprehension of GC non-responsiveness/ resistance is critical for early stratification of these patients and development of alternative therapies. This piece of …

Morin, Koen Parmentier, Cécile Kech, Petra Krystek, Kazushi Noro, Benjamin Becker, Rainer Lohmann, Laure Malleret, Sarit L. Kaserzon, Cécile Miège, Fabrice Alliot, Fabienne Pfeiffer, Denis Crowley, Magdalena Rakowska, Tomas Ocelka, Gi Beum Kim, Laura Röhler

Graduate School of Oceanography Faculty Publications

The quality of chemical analysis is an important aspect of passive sampling-based environmental assessments. The present study reports on a proficiency testing program for the chemical analysis of hydrophobic organic compounds in silicone and low-density polyethylene (LDPE) passive samplers and hydrophilic compounds in polar organic chemical integrative samplers. The median between-laboratory coefficients of variation (CVs) of hydrophobic compound concentrations in the polymer phase were 33% (silicone) and 38% (LDPE), similar to the CVs obtained in four earlier rounds of this program. The median CV over all rounds was 32%. Much higher variabilities were observed for hydrophilic compound concentrations in the …

Considerations And Challenges In Support Of Science And Communication Of Fish Consumption Advisories For Per- And Polyfluoroalkyl Substances, Jonathan Michael Petali, Erin L. Pulster, Christopher Mccarthy, Heidi M. Pickard, Elsie M. Sunderland, Jacqueline Bangma, Courtney C. Carignan, Anna Robuck, Kathryn A. Crawford, Megan E. Romano, Rainer Lohmann, Katherine Von Stackelburg

Graduate School of Oceanography Faculty Publications

Federal, state, tribal, or local entities in the United States issue fish consumption advisories (FCAs) as guidance for safer consumption of locally caught fish containing contaminants. Fish consumption advisories have been developed for commonly detected compounds such as mercury and polychlorinated biphenyls. The existing national guidance does not specifically address the unique challenges associated with bioaccumulation and consumption risk related to per- and polyfluoroalkyl substances (PFAS). As a result, several states have derived their own PFAS-related consumption guidelines, many of which focus on one frequently detected PFAS, known as perfluorooctane sulfonic acid (PFOS). However, there can be significant variation between …

Effect Of Nutrient Reductions On Dissolved Oxygen And Ph: A Case Study Of Narragansett Bay, Hongjie Wang, Daniel L. Codiga, Heather Stoffel, Candace A. Oviatt, Kristin Huizenga, Jason Grear

Graduate School of Oceanography Faculty Publications

To assess the consequences of nutrient reduction strategies on water quality under climate change, we investigated the long-term dynamics of dissolved oxygen (DO) and pH in Narragansett Bay (NB), a warming urbanized estuary in Rhode Island, where nitrogen loads have declined due to extensive wastewater treatment plant upgrades. We use 15 years (January 2005-December 2019) of measurements from the Narragansett Bay Fixed Site Monitoring network. Nutrient-enhanced phytoplankton growth can increase DO in the upper water column while subsequent respiration can reduce water column DO and enhance bottom water acidification, and vice-versa. We observed significant decreases in surface DO levels, concurrent …

Bioconcentration Of Per- And Polyfluoroalkyl Substances And Precursors In Fathead Minnow Tissues Environmentally Exposed To Aqueous Film-Forming Foam–Contaminated Waters, Nicholas I. Hill, Jitka Becanova, Simon Vojta, Larry A. Barber, Denis R. Leblanc, Alan M. Vajda, Heidi M. Pickard, Rainer Lohmann

Graduate School of Oceanography Faculty Publications

Exposure to per- and polyfluoroalkyl substances (PFAS) has been associated with toxicity in wildlife and negative health effects in humans. Decades of fire training activity at Joint Base Cape Cod (MA, USA) incorporated the use of aqueous film-forming foam (AFFF), which resulted in long-term PFAS contamination of sediments, groundwater, and hydrologically connected surface waters. To explore the bioconcentration potential of PFAS in complex environmental mixtures, a mobile laboratory was established to evaluate the bioconcentration of PFAS from AFFF-impacted groundwater by flow-through design. Fathead minnows (n = 24) were exposed to PFAS in groundwater over a 21-day period and tissue-specific …

De-Risking Pretreatment Of Microalgae To Produce Fuels And Chemical Co-Products, Jacob S. Kruger, Skylar Schutter, Eric P. Knoshaug, Bonnie Panczak, Hannah Alt, Alicia Sowell, Stafanie Van Wychen, Matthew Fowler, Kyoko Hirayama, Anuj Thakkar, Sandeep Kumar

Civil & Environmental Engineering Faculty Publications

Conversion of microalgae to renewable fuels and chemical co-products by pretreating and fractionation holds promise as an algal biorefinery concept, but a better understanding of the pretreatment performance as a function of algae strain and composition is necessary to de-risk algae conversion operations. Similarly, there are few examples of algae pretreatment at scales larger than the bench scale. This work aims to de-risk algal biorefinery operations by evaluating the pretreatment performance across nine different microalgae samples and five different pretreatment methods at small (5 mL) scale and further de-risk the operation by scaling pretreatment for one species to the 80 …

Contribution Of High Turbidity To Tidal Dynamics In A Curved Channel In Zhoushan Islands, China, Li Li, Fangzhou Shen, Zhiguo He, Gangfeng Ma, Jiachen Wang, Kailong Huangfu

Civil & Environmental Engineering Faculty Publications

The curved tidal channel, Luotou Deep-water Navigational Channel, is the main channel of the Ningbo Zhoushan Port, which is ranked first in the world. Tidal dynamics in the channel are spatially and temporally asymmetric. In this study, the three-dimensional tidal dynamics in the channel were analyzed using field data and simulated using FVCOM. The results show that the tides in the channel flood/ebb along the northern/southern bank near the bottom/surface layer and these asymmetries are due to the imbalanced Coriolis force, centrifugal force, sea-level gradient, and density gradient. Residual current velocity peaks (0.7 m/s) in the middle of the channel …

Electrophysiological Investigation Of Active-Assisted Vs Recumbent Cycling: A Pilot Study In Healthy Older Adults, Vanessa Harwood, Nicole E. Logan, Alisa Baron, Skye Richards, Raphael Dias, Alex Seng, Emily Jelfs, Christine Marie Clarkin, Christie L. Ward-Ritacco

Kinesiology Faculty Publications

There is a relationship between acute bouts of aerobic exercise and cognition in adults, yet the exact nature of this relationship remains unclear. The current pilot study aims to investigate how different modes of cycling (active-assisted cycling vs recumbent cycling) at different moderate-to-vigorous physical activity (MVPA) intensity levels (prescribed 65–70% Heart Rate Max and self-selected 12–13 Rate of Perceived Exertion) modulate neurocognitive, and behavioral markers of cognition in healthy older adults. A sample of 10 adults (aged 50–74 years) participated in baseline (no exercise), active-assisted, and recumbent cycling interventions at different intensity levels. The P3 event-related potential (ERP), a neural …

Reclaiming Black Spirit: Redefining Social Justice Leadership With And For Black Youth In Jesuit Secondary Schools, Jeremy Divinity

LMU Theses and Dissertations

There were contradictions from the beginning regarding Jesuit education’s mission of faith, which does justice and supports African American male students. Limited research examined the experiences of African American males attending Jesuit secondary schools and their perceived support from Jesuit school leadership in ensuring they had increased feelings of belonging, inclusion, and culture through social justice efforts. In order to address this gap, this qualitative hermeneutic phenomenological study centers on the lived experiences of African American male alumni in Jesuit secondary schools regarding social justice leadership and how they make meaning of their racialized and gendered experiences while attending a …

Opportunities Out Of Challenges In Dental Education: Two Deans’ Perspectives, Clark M. Stanford Dds, Phd, Mha, David Johnsen Dds, Ms

Journal of the American College of Dentists

Addressing the challenges and creating opportunities in dental education requires a multifaceted approach involving curriculum innovation, technological integration, financial support, and mental health resources. Educational institutions must continue to work collaboratively with stakeholders, including government bodies, private sectors, and professional organizations, to develop sustainable solutions. We recognize this will take a multiprong approach. Dentists are great at problem-solving, and we are confident dental education will remain relevant, accessible, and of the highest quality, ultimately leading to a well-prepared dental workforce capable of meeting the rapidly evolving needs of our society.

Prioritizing Well-Being To Advance Dental Education, Sophia G. Saeed Dmd, Mba, Facd, Hubert K. Chan Dds, Facd, Carlos Smith, Romesh P. Nalliah Dds, Mhcm, Facd

Journal of the American College of Dentists

Picture this: robots restoring your teeth and placing implants, digitally created orthodontic treatment plans, 3D-printed dentures, nanohydroxyapatite remineralization of early carious lesions, artificial intelligence (AI) calculating bone loss and identifying potential caries on radiographs, wearable technology providing large amounts of health-related data. It is an exciting time for dentistry and dental education!

Now consider this: the greatest number of faculty vacancies ever in the modern history of dental education, fewer tenured positions than ever before, below-market salaries for dental educators, continually declining reimbursement rates from third-party payers, growing health inequities among the richest and poorest patients, and an increasingly medically …
