The Individual, Collective, And Cyclical Transformational Learning Created By Food Tourism Education, Ziene Mottiar, Mairtin Macconiomaire

European Journal of Food Drink and Society

Research on food tourism education is rare, despite a significant growth in food tourism literature in recent decades. A food tourism module was developed for a new MA Gastronomy and Food Studies at the Technological University Dublin, Ireland in 2017. This article, written by the two module creators and lecturers, analyses reflections of two cohorts of mature post-graduate students (n.14). We explore the transformational role (if any) that this module had. Then, using purposive sampling, employ semi-structured interviews with five graduates who had a collective transformational learning experience – setting up the food tourism network Wicklow Naturally – to explore …

Telling The Stories Of Airwomen In The ‘Forgotten Decade’: 1952-62, Rebecca Hartley, Allan English

Canadian Military History

The Royal Canadian Air Force’s centennial represents a time for reflection. While thousands of young women served in the RCAF during the 1950s, many of their stories have since been overlooked or forgotten. Joining the air force meant access to international travel, new social connections, and valuable vocational training — all of which were relatively unattainable for many women at this time. By studying the photographs, memoirs and collected paraphernalia of Leading Aircraftwoman Ruth Doreen Wright (née Tower), this paper reconstructs an airwoman’s typical RCAF career and her perceived value of her RCAF experience on the rest of her life.

A Computational Framework To Optimize Piezoelectric Power Harvesting From A Uav Wing, Hassan Koko, Gihad Ibrahim

Journal of Aviation Technology and Engineering

This paper proposes a computational framework to optimize the ambient power harvesting from an unmanned air vehicle wing by means of piezoelectricity. First, the wing shape and material are selected based on specific design factors. The wing is then subjected to a vibrational analysis in order to predict the first torsional frequency required to calculate an optimum charging speed. The harvester module is then selected so that the vibration frequency of the charging speed fails within the resonance frequency of the harvester. A finite element modeling is conducted to predict the harvester output voltage during the chagrining speed. Finally, a …

Tubarr: A Self-Hosted Video Archiver, Joshua Sheputa

Honors Program Theses and Projects

Over the past few years, I’ve been slowly expanding my homelab, a personal setup for me to experiment with software, hardware, and deployment configurations. One driving force behind this is my desire to digitize and save anything that is important to me or that I want easy access to. I started with my family’s old CD collection, then moved on to any Blu-rays movie discs we had. Eventually, I started thinking about what else I care about and don’t want to lose track of. This brought me to the thought that any YouTube video that I may want to revisit …

Binuclear Cu(II) complex of salicylic acid (complex molecule) is in the form of “Chinese lantern” and it interacts with uncoordinated piracetam by complicated system of H-bonds. However, according to the Hirshfeld surface analysis a contribution of the O•••H/H•••O contacts is only 24.9% while H•••H and H•••C/C•••H contacts account for …

Preparation Of Manganese-Doped Carbon Quantum Dots@Halloysite Nanotubes Composites Films For Advanced Uv Shielding Properties, Xiao Zhang, Bin Wang

Turkish Journal of Chemistry

The development of Ultraviolet (UV) shielding materials are of great importance to protect human's health concerns and prevent the degradation of organic matters. However, the synthesis of highly efficient UV shielding polymer nanocomposites is currently limited by the agglomeration of inorganic anti-UV nanoparticles (NPs) within the polymer matrix and limited absorption spectrum of UV shielding agents. In this study, highly effective manganese doped carbon quantum dots@halloysite nanotubes composites (Mn-CDs@HNTs/PAS) were successfully synthesized by loading manganese doped carbon quantum dot (Mn-CDs) into UV shielding effective halloysite nanotubes (HNTs) via solvothermal method, followed by polymerization modification. The results show that inorganic NPs …

Turkish Journal of Chemistry

Detection of intracellular biothiols (cysteine (CYS), N-acetyl cysteine (NAC) and glutathione (GSH)) with high-selectivity and sensitivity is important to reveal biological functions. In this study, 2-(2-methoxy-4-methylphenoxy)-3-chloro-5,8-dihydroxynaphthalene-1,4-dione (3) (DDN-O) compound was newly synthesized and used as a fluorogenic probe (detector molecule) in the fluorometric method for the rapid, highly selective and sensitive determination of biothiols. The intensity values (λex = 260 nm, λem = 620 nm) of the product were measured by adding biotihols to the reaction medium at varying concentrations and the glutathione equivalent thiol content (GETC) values of each biotiol were calculated. Using the compoud (3), the reference biotiol …

Understanding Ammonia's Role In Mitigating Concentration Polarization In Anion-Exchange Membrane Electrodialysis, Abdallah Timmaoui, Mahmoud Ferhat, Nesri̇ne Souad Ferhat, Ahmed Hamdi

Turkish Journal of Chemistry

In processes such as electrodialysis, the applied electrical potential is constrained by concentration polarization at the membrane/solution interface. This polarization, which intensifies at higher current densities, impedes ion transport efficiency and may lead to problems such as salt precipitation, membrane degradation, and increased energy consumption. Therefore, understanding concentration polarization is essential for enhancing membrane performance, improving efficiency, and reducing operational costs. This study investigates the impact of ammonia buffer (NH₄⁺/NH₃) on sulfate ion transport through anion-exchange membranes, with a particular focus on limiting current density and concentration polarization under constant current conditions. Our findings demonstrate that ammonia effectively eliminates concentration …

Chilling- And Dark-Regulated Photoprotection In Miscanthus, An Economically Important C4 Grass, Jared Haupt, Katarzyna Glowacka

Department of Biochemistry: Faculty Publications

Tolerance of chilling dictates the geographical distribution, establishment, and productivity of C4 crops. Chilling reduces enzyme rate, limiting the sink for the absorbed light energy leading to the need for quick energy dissipation via non-photochemical quenching (NPQ). Here, we characterize NPQ upon chilling in three Miscanthus accessions representing diverse chilling tolerance in C4 grasses. High chilling tolerant accessions accumulate substantial amounts of zeaxanthin during chilling nights in both field and growth chamber settings. Chilling-induced zeaxanthin accumulation in the dark enhances rate of NPQ induction by 66% in the following morning. Based on our data, the emerging ways for the unique …

Post-Processing National Water Model Long-Range Forecasts With Random Forest Regression In The Cloud To Improve Forecast Accuracy For Decision-Makers And Water Managers, Jacob Matthew Anderson

Theses and Dissertations

Post-processing bias correction of streamflow forecasts can be useful in the hydrologic modeling workflow to fine-tune forecasts for operations, water management, and decision-making. Hydrologic model runoff simulations include errors, uncertainties, and biases, leading to less accuracy and precision for applications in real-world scenarios. We used random forest regression to correct biases and errors in streamflow predictions from the U.S. National Water Model (NWM) long-range streamflow forecasts, considering U.S. Geological Survey (USGS) gauge station measurements as a proxy for true streamflow. We used other features in model training, including watershed characteristics, time fraction of year, and lagged streamflow values, to help …

Local Food System Planning On Multiple Governance Scales: A Grounded Theory Analysis, Decker Ure

Theses and Dissertations

Local food systems (LFS) comprise the people, policies, infrastructure and practices of food production, distribution, and consumption in localized areas. LFS are becoming an increasingly important part of urban sustainable development and have recently gained significant traction in the urban planning and sustainable community spheres. Worldwide shocks to global food systems such as the COVID-19 pandemic and the Ukraine-Russia war have further elevated global interest in LFS, bringing local food to the forefront of many communities as they try to insulate themselves and their food supply from future risk. However, despite this growing interest in and policy momentum for local …

Looking Back To Old New York City In Herman Melville’S “Bartleby”, Shawn Thomson

Literatures and Cultural Studies Faculty Publications

Though “Bartleby, the Scrivener” takes place in the three-block area in and around the lawyer’s Wall Street offices, the uptown attitudes toward city life of the suburbs inform the lawyer’s relationships to his urban or downtown space. Wall Street stands as a central feature of the island city’s history, taking its name from a physical wall built to protect the Dutch from the British and the Indians. As a result, Wall Street served to differentiate the suburban from the urban confines of the city. Through the position of the lawyer in the Master Chancery office on Wall Street and his …

Addressing A Lack Of Counseling Programs To Diminish The Psychological, Emotional, And Mental Impacts Of Church Closure Grief, Marcel Berrios

Doctoral Dissertations and Projects

Besides spiritual activities, the social activities that happen in church buildings are vital to the functioning of most communities; therefore, churches play a central role in the social fabric and social infrastructure of communities in ways not necessarily thought about until they are no longer around. The looming absence of this role or function of the church becomes the overarching focus to address when an announcement is made that a church is permanently closing. Lost in navigating the business and community aspects of a church closure is the congregation's metamorphic spiritual, emotional, and psychological journey. Subsequently, many church members are …

The Impact Of Policing On Female Police Officer’S Parenting Styles, Debbie Michelle Chambers

Doctoral Dissertations and Projects

This qualitative transcendental phenomenological study was to explore the lived experiences of female police officers with children in rural Georgia. For years, women have been proving themselves in this profession only to face gender inequality, discrimination, harassment including physical, emotional, and sexual, and skepticism from the community. Despite these barriers, females have achieved high-ranking positions in local and state agencies and federal law enforcement. This achievement has come with a price that could impact how the female officer parents her children. Several studies have been conducted on a variety of factors impacting the female police officer, such as rank, position, …

A Study Of Thomas Oord’S Open Theism And Theodicy, Olaoluwa Apata

Doctoral Dissertations and Projects

Open theism’s opposition to the traditional Christian view and its rejection of the classical definitions of God’s attributes, character, and divine impassibility continually creates a point of contention between the two worldviews. As one of the leading voices in this movement, Thomas Oord offers what can be described as a refined argument in support of Open theism in contemporary theological and philosophical studies. His open theism holds that due to God’s kenotic act and uncontrolling love, his ability to know the future is limited and he cannot prevent evil. Oord introduces his version of open theism with the goal of …

The Influence Of Socioeconomic Status On Youth Enrolled In Public Urban High Schools: A Transcendental Phenomenological Study, Destiny Breanna Carrington

Doctoral Dissertations and Projects

The purpose of this transcendental phenomenological study was to describe the lived experiences of low socioeconomic status (SES) students who were enrolled in a public urban high school. The theory guiding this study is the theory of social cognition, as it describes the fact that since learning happens in social environments, when students are properly supported in the classroom it can change their overall outcomes. Students of low SES may need extra motivation in the classroom, diverse types of instruction, and other positive reinforcement to help them perform better. Reciprocal determinism is at the center of the vortex for social …
