Vanet Broadcast Protocol: A Multi-Hop Routing Framework For Vehicular Networks In Ns-3, William M. Bjorndahl

LMU Theses and Dissertations

Vehicles are more frequently being built with hardware that supports wireless communica- tion capabilities. Dedicated short-range communications (DSRC) is a standard that enables the hardware on vehicles to communicate with one another directly rather than through external infrastructure such as a cellular tower. With DSRC supporting small-range communications, multi-hop routing is utilized when a packet needs to reach a long-range destination. A vehicular ad-hoc network (VANET) broadcast protocol (VBP) was developed. This thesis introduces VBP, an open-source framework for simulating multi-hop routing on mobile and wireless vehicular networks. VBP is built for the routing layer of the network simulation tool …

Challenging Racism In Catholic Schools Through Intimate School Leadership: Counternarratives Of Black Catholic School Leaders, Michael Santa Maria

LMU Theses and Dissertations

Conversations regarding racial equity are uncomfortable for many Catholic school leaders. This is due to a lack of clarity between Catholic social teaching (CST) and its implementation regarding racial justice among Catholic schools. This necessitates coherent guidance to address systemic racism in Catholic education which responds to the need for greater equity, inclusion, and antiracism in its Catholic schools. The purpose of this study was to work with Black Catholic school leaders to understand how they operationalize antiracism in their leadership practice. To understand this paradigm, this study addressed two research questions: (1) How do Black leaders experience their role …

Graduate School of Oceanography Faculty Publications

The correct prediction of the shape and strength of density dependence in productivity is key to predicting future stock development and providing the best possible long-term fisheries management advice. Here, we identify unbiased estimators of the relationship between somatic growth, recruitment and density, and apply these to 80 stocks in the Northeast Atlantic. The analyses revealed density-dependent recruitment in 68% of the stocks. Excluding pelagic stocks exhibiting significant trends in spawning stock biomass, the probability of significant density dependence was even higher at 78%. The relationships demonstrated that at the commonly used biomass limit of 0.2 times maximum spawning stock …

Global Distribution Of The Cold-Water Coral Lophelia Pertusa, R. Tong, Andrew J. Davies, A. Purser, X. Liu, F. Liu

Graduate School of Oceanography Faculty Publications

Lophelia pertusa plays an important role as a major contributor to many cold-water coral reefs, supporting a high diversity of associated benthic and benthopelagic species. Due to the high sensitivity of L. pertusa to human activity, it has been classified as indicator species for Vulnerable Marine Ecosystems. However, the global spatial distribution of L. pertusa is far from well known. In this study, a database of L. pertusa presence data was compiled derived from the large number of L. pertusa occurrence records appearing in recent years. In conjunction with data layers covering a range of environmental drivers, habitat suitability for …

The Developing Brain: Considering The Multifactorial Effects Of Obesity, Physical Activity & Mental Wellbeing In Childhood And Adolescence, Nicole E. Logan, Christie L. Ward-Ritacco

Kinesiology Faculty Publications

Obesity during childhood has been associated with many important physiological and neurological health considerations. Specifically concerning are the associations between youth obesity and declines in mental health, as shown with increasing rates of adolescent depression and anxiety worldwide. The emergence of mental health disorders commonly arises during adolescent development, and approximately half the global population satisfy the criteria for at least one psychiatric disorder in their lifetime, suggesting a need for early intervention. Adolescence is critical time whereby brain structure and functions are not only negatively associated with obesity and declines in mental health, while also coinciding with significant declines …

Bayesian Methods For The Design And Analysis Of Cluster Randomised Controlled Trials, Benjamin Gary Jones

Other Faculty of Health Theses

Cluster Randomised Controlled Trials involve randomising groups of participants, rather than the individual participants themselves, whilst the outcomes are measured on the participants. Whilst there are a number of practical and methodological advantages to such a design, there are also statistical implications, both in terms of study design and sample size calculation, and in analysis. The methodology underpinning the cluster randomised design is now well-established in the statistical literature. However, the overwhelming majority of methodological developments to date have been within the frequentist paradigm, and as such, there is an opportunity to explore methodological developments in the context of Bayesian …

Novel Approaches To Assess Cellular Interactions And Their Role In The Pathology And Treatment Of Lymphoproliferative Disorders, Frances Hilary Rose Frend

Other Faculty of Health Theses

Background: Migration and homing are essential to B-lymphocyte mediated immunity, and are driven by rapid, directed, and appropriate reorganisation of the actin cytoskeleton. Important observations have linked the cytoskeletal-rearrangements made by leukaemic B-lymphocytes of chronic lymphocytic leukaemia (CLL) to disease pathology. In particular, cytoskeletal alterations mediated by B-cell receptor (BCR) engagement or chemokine-binding are recognised to be central to the migration of CLL cells to lymphoid tissues, where they engage in the complex cellular and molecular interactions that underlie their survival, proliferation, and drug resistance. Further emphasising this importance, has been the observation that highly effective small molecule inhibitors that …

Nitrite And Insulin Lower The Oxygen Cost Of Atp Synthesis In Skeletal Muscle Cells By Pleiotropic Stimulation Of Glycolysis, Rosie Donnell

Other Faculty of Health Theses

Dietary nitrate lowers the oxygen cost of submaximal exercise, but precise mechanistic insight into how this occurs is lacking. Research suggests that dietary nitrate may render oxidative ATP synthesis more efficient, but evidence is inconclusive at present. This thesis aimed to establish how nitrite (a reduced form of nitrate) affects the bioenergetics of cultured skeletal muscle cells. Comparison between the acute effects of nitrite and insulin, a hormonal regulator of muscle function that increases mitochondrial efficiency, was explored to assess possible mechanistic overlap. Calculation of real-time intracellular ATP synthesis rates from simultaneous oxygen consumption and medium acidification measurements revealed the …

Prediction Of Cardiometabolic Risk In Children, Olubukola Ajala

Other Faculty of Health Theses

Background: Three decades of clinical research have demonstrated that the risks of atherosclerotic cardiovascular disease (ACVD: coronary disease and ischaemic stroke), and the closely related type 2 diabetes (T2D) are established and influenced by events during childhood. This is at least partly because childhood obesity usually leads to adult adiposity; so, the currently high prevalence of adult cardiometabolic disease, means that obesity needs to be identified as early as possible, ideally in childhood. Screening for obesity largely relies on anthropometric measurements like body mass index (BMI), however this has many limitations including its inability to distinguish lean from fat mass. …

Contributions Of Source-Constrained Search And Late Monitoring To Recall Accuracy, James Randle

Other Faculty of Health Theses

This thesis aimed to investigate in detail the processes underlying the control of recall accuracy. It is believed that recall accuracy control comprises processes occurring at memory search and post-retrieval. There is a large body of research concerning post-retrieval monitoring processes; however, less is known about how memory search is constrained and what factors affect this process.Chapter 2 developed and tested a new paradigm for measuring the accuracy of constrained search and monitoring processes simultaneously. Participants were able to selectively retrieve one of two lists irrespective of which list was the target list, indicating successful constrained search. A key role …

Dementia Friendly Flying: Investigating The Accessibility Of Air Travel For People Living With Dementia, Kate Turner

Other Faculty of Health Theses

A diagnosis of dementia should not mean the end of a person’s ability to participate in meaningful activities. However, accessibility for people living with dementia requires improvement across a range of settings. Anecdotal evidence and critical incident reporting suggests that air travel is not meeting the needs of people with dementia, although evidence-based research into air travel and dementia is extremely limited. This research bridges the gap in the evidence-base on the accessibility of air travel for people living with dementia from within the United Kingdom by: 1) Exploring the experiences of air travel of 10 people living with dementia …

Atrial Fibrillation In Middle-Eastern Arabs And South Asians: Studies From A 20-Year National Registry In Qatar, Amar Mohammad Amin Farhan Salam

Other Faculty of Health Theses

Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice accounting for approximately one-third of hospitalizations for cardiac rhythm disturbances and is associated with increased risk for stroke, heart failure and death. The epidemiology and clinical features of AF have primarily been characterized in whites of European-descent. The world literature on the epidemiology of AF among different ethnicities is very limited with most of the published reports of AF in non-white ethnicities focusing mainly on black (African-American) patients. The current work represents structured and staged examination of AF in two ethnic groups where very limited literature is available …

An Earthly Response To Movement. Moving Images Diffracted Through New Materialism, Emilio Chapela Pérez

School of Art, Design and Architecture Theses

This practice-led research follows my exploration of the Sierra Negra astronomical observatories in Mexico, as well as other sites and temporalities where my practice has drifted: it flows from the heights of two volcanos, across Idaho during a total eclipse of the sun, and into the waters of the Usumacinta River. It proposes an ‘earthly’ (Latour 2016) moving image practice that considers the planet as a source of movement, effects and, affects: a vibrant entity that is not seen as static or mechanical, but one that ‘is moved’ (Serres 1995) because it is agitated by the liveness of matter and …

Architectural Design For Dementia: Exploring Alternate Contemporary Cultures Of Residential Care Design, Ricky Burke

School of Art, Design and Architecture Theses

Architectural Design for Dementia: exploring alternate contemporary cultures of residential care design. The Alzheimer's Association (2018) projected the number of people living with a dementia diagnosis to surpass 2 million, reaching 1 in 37.5 of the population of the United Kingdom by 2051: up from 1 in 79 in 2015. This growth in rate and number coincides with an ageing population and a decline in the relative number of people able to care for the needs of people suffering difficulties associated with the symptoms of their diagnosis. The move to a residential care home is not only a viable but …

Molecular Control Of The Migratory Phase During Cutaneous Wound Healing, Chloe Elizabeth Bolton

Other Faculty of Health Theses

Superficial cutaneous injuries occur on a huge scale across the globe; while most will resolve without intervention or any lasting damage, many will experience complications that arise through delayed healing or as a consequence of the skins protective barrier being breached. The migration of cutaneous cells across a wound site is a crucial factor in establishing permanent restoration of the skins integrity. This study provides insight into molecular events that facilitate the migratory ability of cutaneous cells during this phase of the healing process. Through subcellular analysis, molecular manipulation and various imaging techniques of in vivo and in vitro wound …
