Tolkien’S Orphaned Heroes: Kullervo, Húrin And The Limits Of Fostering, Deidre Dawson

Journal of Tolkien Research

Tolkien’s legendarium features many characters who have lost one or both parents through death or abandonment, and who are consequently fostered or adopted. While there are many positive depictions of fostering in the legendarium, the cases of Kullervo and especially Túrin Turambar stand out because of their similar tragic outcomes involving sibling incest followed by suicide. The contrast between the depiction of fostering in these stories is stark: The Story of Kullervo depicts a case of poor fostering involving violence and neglect, whereas The Children of Húrin describes a loving and nurturing foster environment for its hero, Túrin. Both tales …

Development Of A Reaction Wheel Testbed With Object Tracking, Abigail Jocelyn Romero, Harvey Mallard Perkins, Stephen Thiam-Choy Kwok-Choon

Small Satellite Conference

This paper discusses the design, fabrication, and testing of a single axis reaction wheel testbed with optical object tracking. Reaction wheels enable satellites to control their attitude.

The Cosmic X-Ray Background Nanosatellite 3 (Cxbn-3): Toward An Improved Understanding Of Diffuse Emission Produced By High-Redshift Active Galactic Nuclei, Breno Mascarenhas Pontes, Brannon Jones, Thomas Pannuti, Jaden Yates, Benjamin Malphrus

Small Satellite Conference

The Cosmic X-ray Background (CXB) is the diffuse emission of hard X-rays (3-300 keV) that is observed across the whole sky. The general consensus for the sources of the CXB (particularly at higher energies) are heavily obscured active galactic nuclei (AGN) located at a moderate redshift (z ≈ 1). To explore the properties of the CXB further (such as whether flux variations are present at different angular scales), the Space Science Center (SSC) at Morehead State University (MSU) is developing CXBN-3 (Cosmic X-ray Background Nanosatellite 3), a nanosatellite designed to measure the intensity of the CXB within the energy …

In the CubeSat platform, the PAT system relies on a satellite attitude determination and control system (ADCS) for body …

Testing Metabolic Cold Adaptation And The Climatic Variability Hypothesis In Two Latitudinally Distant Populations Of A Supratidal Water Beetle, J.M. Miron-Gaton, J. Velasco, S. Pallares, A.J. García-Meseguer, A. Millan, David T. Bilton

School of Biological and Marine Sciences

Temperature significantly impacts ectotherm physiology, with thermal tolerance and metabolic traits typically varying with latitude across species ranges. The drivers of this variation remain unclear, however, despite obvious consequences for population persistence and conservation in the face of ongoing global change. This study explored local adaptation and phenotypic plasticity of metabolic rates and thermal limits in the supratidal rockpool beetle Ochthebius lejolisii. Using populations from localities at different ends of the species range that experience contrasting thermal variability, we simultaneously tested two of the major paradigms of spatial physiological ecology: metabolic cold adaptation (MCA) and the climatic variability hypothesis (CVH). …

Nebraska Conventional Farmers’ Perspectives Toward Agricultural Hemp: A Qualitative Insight Guided By The Diffusion Of Innovations Theory, Blake C. Colclasure, Nicholas Gray, Laura E. Young

Journal of Extension

The legalization of hemp cultivation in the United States has provided opportunities for farmers to grow a new crop. Despite these opportunities, significant social, economical, and technical challenges to growing hemp have been well documented. The purpose of this research was to explore Nebraska conventional farmers’ perceptions toward hemp cultivation. Using the diffusion of innovations theory as a framework, one-on-one interviews were conducted with seven conventional farmers in Nebraska. Data were analyzed using deductive coding methods. Results are presented in four emergent themes describing farmer perceptions: 1) limited prior exposure; 2) perceived technical challenges; 3) advantages; and, 4) impartial feelings.

Housing is a basic need. The National Association of Community Development Extension Professionals (NACDEP), Land Use Planning Community of Practice held a virtual forum in December 2021 on the national housing crisis. The session revealed common challenges communities face when addressing these issues locally. As a follow-up to that session, this paper summarizes Extension perspectives on community housing issues discussed during the session, reviews the literature on Extension programs related to housing, and makes the case for a national peer learning and communications network to address these difficult and urgent community housing challenges.

Heirs Property And The Necessary Role Of Extension In Preventing Land Loss Through Partitioning, Kurt Smith

Journal of Extension

Land loss in the United States continues to be a threat to our inventory of natural resources. The problem of co-tenancy or heirs’ property is a particular and persistent problem throughout the United States leading to fragmentation of property, and the complete loss of forest and farmland. Maintaining enough forest and farmland is essential to local, regional, and international economies. Much can be done to ameliorate the problem through education about the value of successional planning and the requirements of your state regarding the legal practice known as partitioning.

The distinction between problematic money issues and money disorders, as well as overspending and compulsive buying, is clarified. The study uses empirical testing on problematic money behaviors and their association with fundamental money management practices to inform the development of comprehensive financial training and counseling …

Sales Professional Preservation: Examining The Impact Of Incongruent Ideological Belief Systems On Intentions To Quit Among Sales Professionals, Brian Lee Morgan

Dissertations

Organizations that lead with ideologies of moral tradition, politics, and social economics are playing a losing game. The ideological belief system congruence within the organization between leaders and members creates a better atmosphere with less turnover and better recruitment. Sales professionals want an environment free of ideological incongruence. Without ideological alignment, they will defect from the organization. Leaders are miscalculating the negative impact on members’ intentions to quit when they are faced with leaders acting upon ideology changes that affect the member-customer ecosystem. In addition, leaders should be aware of the personal attributes that can exacerbate turnover and work to …

A Qualitative Study On Workplace Mental Wellbeing In The Singapore Context, Chad C E Yip, M. Anthony Machin, Yong Wah Goh

The Qualitative Report

Workplace wellbeing is essential for the employee as well as the organisation, but it may not adequately capture the way wellbeing is experienced in Singapore due to its diverse multi-ethnic society imbued with Eastern and Western values. The present study explores Singaporean employees’ understanding and perspectives in relation to how they experience wellbeing at the Singapore workplace. With a total of 31 participants consisting of full-time Singaporean employees from 17 industries, we used reflexive thematic analysis (Braun & Clarke, 2013) to interpret the data and develop the themes. These 13 themes are: accomplishment, autonomy, co-worker relationship, employee recognition, fairness, learning …

The Genii Loci In The Midst Of Middle Earth, Richard Angelo Bergen

Mythcon

Several scholars, including Tom Shippey, Philip Mitchell, and Gordon Sleuthag, all agree that Tom Bombadil is, among other things, Tolkien’s representation of the genius loci of the Old Forest. The argument is plausible and coherent, but there is much more that can be said about the spirits of places in Tolkien’s legendarium, and the traditions he draws from to craft his world of storied and mutable place. In general, an affection and attention for the local, which Tolkien extols in his letters and fiction, is rather amenable to ideas concerning the genius loci, as theorists such as Yi-Fu Tuan and …

Investigating The Effects Of Visual Feedback On Muscle Activity, Heart Rate, Rpe, And Perceptions Of Performance In Ballet Dancers, Lilah A. Duboff, Sarah Dipasquale, Stephen Ives

International Journal of Exercise Science

International Journal of Exercise Science 17(1): 1056-1067, 2024. Extreme postures and imbalances in neuromuscular activity may place classical ballet dancers at higher risk of injury. Dance studio mirrors provide visual feedback by which a dancer can self-correct their body position and alignment, but have been suggested to negatively impact kinesthetic abilities and decrease performance capabilities. Thus, we investigated the effects of a mirror on muscle activity of the quadriceps, heart rate (HR), rating of perceived exertion (RPE), and qualitative performance. A lack of visual feedback would increase muscle activity of the quadriceps, HR, and RPE, and decrease self-reported perception of …

“I Desire The Road. . . [But] [R]Oads Were Made For Young Men, Not Middle-Aged Women”: Ista’S Journey From Dowager To Paladin, Robin Anne Reid

Mythcon

Scholarship on Ista, Dowager Royina of Chalion, was minimal until the most recent anthology on Bujold’s work was published with four essays (out of 14, 28%) that focus on Ista, either as the primary focus of the essay (Yung Lee, Herington,), or as one of two characters analyzed (Palmer-Patel, MacDonald). These essay focus on queer and/or feminist readings of Ista (Yung Lee, MacDonald, Herington), and on analyzing the paradox of free will and fate in the Chalion duology (Palmer-Patel). In “I desire the road,” (Bujold’s emphasis), I build on these essays, all of which I consider convincing and strongly argued) …
