International Journal of Aviation, Aeronautics, and Aerospace

Composite materials are utilized in many industries today due to its high performance and lightweight. However, the part manufacturing process of traditional composites is complicated and often involves high cost. The molds used for composite manufacturing are usually one of the contributors to the high part manufacturing cost. The authors demonstrated in this paper a manufacturing process for a carbon fiber reinforced composite rocket payload housing using an additively manufactured polylactic acid (PLA) payload housing core. The paper also demonstrates the designing and manufacturing of a functional product, which was used in a real-life application, achieved by college undergraduate students. …

Creation Of Two Valid Scales: Willingness To Fly In An Aircraft And Willingness To Pilot An Aircraft, Stephen Rice, Scott R. Winter, John Capps, Justin Trombley, John Robbins, Mattie Milner, Tracy L. Lamb

International Journal of Aviation, Aeronautics, and Aerospace

The purpose of the current study was to develop two scales that could be used concurrently or independently to measure passenger willingness to fly (WTF), and aviator willingness to pilot (WTP), respectively. This is especially useful to determine challenges involving acceptance of new aviation technology for both pilots and passengers. There were five stages in developing the WTF scale for passengers, following Hinkin’s scale development process. Cronbach’s Alpha and Guttmann’s Split Half tests were used to confirm high internal consistency and reliability, while factor analysis was used to confirm construct validity. The scale was tested in order to confirm sensitivity …

On July 23, 2019, the Federal Aviation Administration (FAA) expanded the Low Altitude Authorization and Notification Capability (LAANC)—the system that processes airspace approvals for sUAS operators in controlled airspace—to include recreational operations. Researchers sought to collect and evaluate 30 days of UAS operational activity in controlled airspace using UAS detection equipment. Detected UAS flight data was compared against UAS Facility Maps and LAANC approval data to assess UAS operator compliance and behavior patterns. Researchers documented 94 LAANC approvals and detected 271 UAS flights within the sample area during the sampling period. The research team noted that UAS detections exceeded LAANC …

Automatic Gaze Classification For Aviators: Using Multi-Task Convolutional Networks As A Proxy For Flight Instructor Observation, Justin Wilson, Sandro Scielzo, Sukumaran Nair, Eric C. Larson

International Journal of Aviation, Aeronautics, and Aerospace

In this work, we investigate how flight instructors observe aviator scan patterns and assign quality to an aviator's gaze. We first establish the reliability of instructors to assign similar quality to an aviator's scan patterns, and then investigate methods to automate this quality using machine learning. In particular, we focus on the classification of gaze for aviators in a mixed-reality flight simulation. We create and evaluate two machine learning models for classifying gaze quality of aviators: a task-agnostic model and a multi-task model. Both models use deep convolutional neural networks to classify the quality of pilot gaze patterns for 40 …

The Struggles And Triumphs Of The Invisible Subject: The Experiences Of Mature Women Students Caring For Those With Learning Disabilities Whilst Studying In Higher Education, Kitty King

Plymouth Institute of Education Theses

The caring role entails substantial social, physical, emotional and financial costs, especially for women with caring responsibilities, which presents challenges and restrictions for them when participating in activities outside the care-giving domain, such as engagement in education. Against these odds and despite the considerable demand caring places upon carers, a limited number of mature women caring for those with learning disabilities are navigating access to and participation in Higher Education. Considering the effort that this group of women expend attempting to combine multiple identities, and compared to the considerable research in Higher Education about the experiences of other groups of …

Relational Rural Geographies, Resilience, And Narratives Of Small-Scale Fruit Farming In The Metropolitan Countryside Of Rio De Janeiro, Brazil, Felipe Da Silva Machado

School of Geography, Earth and Environmental Sciences Theses

This thesis analyses the processes through which farming and rural communities in transition economies build resilience in the face of changes to rural areas caused by globalisation and urbanisation. The study is based on analysis of how urban-rural interactions have affected small-scale farming in the metropolitan countryside of Rio de Janeiro, Brazil, an area where land-use, economic and environmental policies and urban land speculation have prompted increasing competition between agricultural, industrial, residential and conservation land uses within a highly multifunctional countryside. To achieve this, the research examined the pressures facing farmers in areas affected by the metropolitan dynamics of Rio …

Eco-Engineering Of Coastal Infrastructure: A Design For Life, Kathryn O'Shaughnessy

School of Geography, Earth and Environmental Sciences Theses

Coastal urbanisation has driven humans to build artificial defences to protect infrastructure from rising sea level, erosion and stormier seas. Artificial structures are proliferating in the coastal and marine environments (“ocean sprawl”), resulting in a loss of natural habitat, species diversity and ecosystem services. To mitigate the impacts of ocean sprawl, the practice of eco-engineering of coastal infrastructure has been developed. A strong evidence base in support of eco-engineering is growing, yet there remain critical knowledge gaps. This work investigated the ecology of artificial structures and their ability to be enhanced in order to increase species diversity, addressing five knowledge …

Understanding The Fate Of Active Pharmaceutical Compounds In Waters Receiving Poorly Or Untreated Wastewater For The Development Of A Dedicated Environmental Risk Assessment Approach, Simone Bagnis

School of Geography, Earth and Environmental Sciences Theses

The global increasing consumption and production of active pharmaceutical ingredients (APIs) is of a growing environmental concern. The inherently biological activity of APIs creates a concern of potential ecotoxicological effects even at very low concentrations. Such risk is particularly exacerbated in low and low-middle income countries (LLMICs) where it is common the practice of direct discharge of untreated wastewater (DDUW) into surface waters, which creates a heavily polluted area downstream, described as the “impact zone”. Little is known about the environmental fate of APIs in this area. Nevertheless, measured environmental concentrations (MECs) of LLMICs show higher concentrations than for high-income …

Controls On Stratigraphy And Architecture Of Shallow-Water Deltas: Examples From The Early Cretaceous Of Central-Eastern Spain, Grant Cole

School of Geography, Earth and Environmental Sciences Theses

Deltas form where a river meets a standing body of water (e.g. ocean) and deposits its sediment load. They are sensitive recorders of the interplay of fluvial (river) processes, that deliver the sediment to the standing body of water, and wave and tidal processes that redistribute the delivered sediment. When basinal (waves / tides) processes cannot sufficiently redistribute the delivered sediments, river-dominated deltas prevail, which are fantastic recorders of autogenic (internal to the delta) processes that control its overall evolution and internal architecture. Allogenic (external to delta) processes, such as tectonics, can influence and modify the river produced architecture. Therefore, …

The Concept Of Confidence Of Older People Living With Frailty And Implications For Practice, Frazer Underwood

School of Nursing and Midwifery Theses

Background Our human world is aging. The prevalence of older people living with syndromes of frailty is growing too. Frailty syndromes, such as falls, immobility, delirium, incontinence and susceptibility to medication side effects, are leading causes of acute hospitalisation of older people. Confidence is recognised to impact on individuals’ physical health and mental well-being, despite it not being clearly expressed in the literature. Health and social care policy and practice now focus on frailty interventions to reduce long-term demands of this growing population. Understanding the relationship of the concept of confidence and its associated impact on the physical health and …

A High-Resolution Palaeoecological Study Of Land Use Change During Late Prehistory On Exmoor, Havananda Ombashi

School of Geography, Earth and Environmental Sciences Theses

Palaeoecological studies have proven to make significant contributions to two large ongoing debates that include the influential power of climate and the impact of human land management on the vegetation patterns in certain areas in the UK and Northwest Europe. The need and importance for higher resolution vegetation reconstructions has long been recognised in the wider literature. The main focus of this research is to further understand the relationship between human behaviour, climate and land cover change on Exmoor, of which the upland areas are comparable with others found in Britain and Northwest Europe. High resolution records of pollen, NPP …

This contribution forms a blueprint for future studies using sediment tracing, radionuclide dating, Bayesian Mixing Models and soil erosion mapping, and their reciprocal integration in this challenging environment. An integrated quantitative assessment of soil erosion and sediment dynamics in the Lake Manyara catchment, northern Tanzania, revealed drastic changes in land cover, a tenfold increase in upstream sediment yield, and a fivefold increase in downstream lake sedimentation …

Heathland Restoration After Mineral Extraction, Mary Louise Lane

School of Geography, Earth and Environmental Sciences Theses

Restoration Ecology has been developed over the last 40 years in efforts to better understand how to restore, recreate or reclaim land damaged by human activities. Lowland heath is one of the more difficult habitats to recreate due to the complicated interactions of soil chemistry and plant physiology and structure. This study investigated the ecological restoration of heathlands at a china clay mineral extraction site in the UK. Assessment of historical restoration practices revealed that previous work carried out on the study site is not achieving Atlantic Lowland Heath (ALH) and that specific amendments might be necessary. Consequently, work carried …

The Sheeted Dyke-Gabbro Transition Zone: The Key To Unravelling The Palaeomagnetic Record Of The Oman Ophiolite, Louise Maria Theresia Koornneef

School of Geography, Earth and Environmental Sciences Theses

The Oman ophiolite is a natural laboratory for the study of processes operating above a nascent subduction zone. It formed in the Late Cretaceous by supra-subduction zone spreading and shortly afterwards was emplaced onto the Arabian continental margin. Twelve massifs in the ophiolite expose complete sections of the Neotethyan oceanic lithosphere, including upper mantle peridotites, lower crustal gabbros, and upper crustal sheeted dykes and lava flows. Previous palaeomagnetic studies have suggested that the southern massifs of the ophiolite were affected by a large-scale remagnetization event during emplacement, which completely replaced original remanences acquired during crustal accretion. In contrast, primary magnetizations …

An Assessment Of The Legality Of Fake News Within The Mainstream Media – With Specific Regard To Its Influence On The Political Climate, Ayesha Faraj Al-Nuaimi

Plymouth Law Review

This article aims to investigate whether the law and regulation provided by the government is sufficient in tackling the increasing issue of fake news (FN) ‘‘a false story that appears to be news, usually created to influence political views’’.2 An examination on whether increased regulation would restrict the United Kingdom’s tradition of a free, investigative press, will be comparatively analysed to serve a contrast in perspectives to the laxer attitudes of the American media system. With the rapid evolution of technology, the radical influence FN has on the political climate will likely increase. A 2015 poll showed that 41% of …

Can The Law On Sexual Consent And Related Rules Of Evidence Provide Adequate Protection To Vulnerable Victims And Defendants Who Are Subject To False Allegations? If So, Do Juries Jeopardize This?, Casey Chard

Plymouth Law Review

Sexual consent is a sociolegal principle that is designed to protect personal autonomy. This article will evaluate and challenge the legal concept of sexual consent and whether the current law is sufficiently designed so that it is capable to protect both vulnerable victims and defendant simultaneously in rape and sexual assault trials. A common theme throughout will be rape myths and how these can negatively affect jurors and as a result, raise the question, should jurors sit on rape and sexual assault trials?

Will The United Kingdom’S Exit From The European Union Have An Impact On International Arbitration Within The United Kingdom?, Hugo Persad

Plymouth Law Review

This article will aim to assess whether Britain’s exit from the European Union will impact arbitration. This is a very topical issue as no one can accurately predict what direction this will take as there are many avenues that need to be explored. As Lord Goldsmith QC suggests: "The success of London arbitration depends in no way upon the UK’s membership of the EU;"2 although, as the New Law Journal argues: ‘London will gain a distinctly competitive edge as a seat for arbitration in comparison to other European cities’3 in relation to the resurrection of anti-suit injunctions. Examination of the …
