Extension Efforts To Address The Current National Housing Crisis, Michael J. Dougherty, Melissa B. Hamilton, Bradley Neumann Aug 2024

Extension Efforts To Address The Current National Housing Crisis, Michael J. Dougherty, Melissa B. Hamilton, Bradley Neumann

Journal of Extension

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.


Recentering Community Nutrition Education: A New Framework For Food Insecurity Understanding, Chasity Tompkins Aug 2024

Recentering Community Nutrition Education: A New Framework For Food Insecurity Understanding, Chasity Tompkins

Journal of Extension

While strategies may differ across geographical regions, FACS Extension professionals work to enhance nutrition education and increase food security in their communities. The four dimensions of food security developed by The Food and Agricultural Organization were reconceptualized to understand food security on an individual or at a community level. Using experiences from a summer internship with two urban counties, the EEUESA Model described here was designed to aid FACS Extension professionals in their efforts for nutrition education and to better understand how programming targets food security in their communities.


Radiating Excellence: Leadership Styles In Nuclear Power That Influence Operators Towards Industry Best Practices, Joshua Copeland Aug 2024

Radiating Excellence: Leadership Styles In Nuclear Power That Influence Operators Towards Industry Best Practices, Joshua Copeland

Dissertations

Poor leadership is the root cause for the three most significant accidents in the nuclear industry. The purpose of this research was to determine the best leadership characteristics of operating supervisors at nuclear plants that could help prevent future accidents from happening. Operating supervisors are the leaders that have the greatest impact on how safe the nuclear plant is operating. A mixed method approach was used, where the quantitative study surveyed 77 supervisors about their leadership style and how well they influence standards adherence, and the qualitative study interviewed 11 subordinates of supervisors to determine how supervision helps them follow …


A Qualitative Study On Workplace Mental Wellbeing In The Singapore Context, Chad C E Yip, M. Anthony Machin, Yong Wah Goh Aug 2024

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 …


Global Constraints On Exhumation Rates During Porphyry Copper Formation And Supergene Enrichment: Applications To Exploration As Illustrated From The Central Andes, Laura Evenstar, Simon Dahlström, Adrian Hartley, T. Campbell Mccuaig, Anne Mather, Joe Shaw Aug 2024

Global Constraints On Exhumation Rates During Porphyry Copper Formation And Supergene Enrichment: Applications To Exploration As Illustrated From The Central Andes, Laura Evenstar, Simon Dahlström, Adrian Hartley, T. Campbell Mccuaig, Anne Mather, Joe Shaw

School of Geography, Earth and Environmental Sciences

Currently, 60% of the world’s copper production comes from porphyry copper deposits, often significantly enriched by surface weathering. This paper uses new global datasets and previous work to review the critical processes required for porphyry copper formation and supergene enrichment. Porphyry copper formation requires a subducting arc to create a source magma which traverses a thickened crust subject to high exhumation rates during formation, ranging from 100’s to 1,000’s m/m.y. High exhumation rates potentially trigger magma decompression, causing fluid release, opening fluid pathways along faults and lineaments and/or facilitating telescoping, whereby early porphyry-style mineralization is overprinted and enriched by high-sulfidation …


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 Aug 2024

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). …


Sealed In The Sacred Realm: Coming Of Age In The Liminal Spaces Of Hyrule, Alicia Fox-Lenz Aug 2024

Sealed In The Sacred Realm: Coming Of Age In The Liminal Spaces Of Hyrule, Alicia Fox-Lenz

Mythcon

The Legend of Zelda franchise commonly uses alternate dimensions or worlds in its storytelling. These dimensions are often tied to darkness — being a place where evil waits, gathering strength, or a sister-world that has fallen to evil and needs liberation — providing the hero, Link, with the primary conflict driving his adventure. Alongside these larger worlds that provide conflict, there exist smaller dimensions, liminal spaces where Link and a small cast of other heroic characters are brought for physical and spiritual maturation. We will discuss how these liminal spaces function as doors through which the player as Link crosses …


Eleanor Arnason’S Fantastic Mitochondrial Humor, Sandra Lindow Aug 2024

Eleanor Arnason’S Fantastic Mitochondrial Humor, Sandra Lindow

Mythcon

In this essay I explore Brian Attebery’s description of mitochondrial fantasy to explain how humor works in Eleanor Arnason’s short fantastic fiction. Mitochondria are the energy powerhouses in cells. They are symbiotic creatures that once were separate but became an evolutionary part of a female egg cell, providing a history that can be traced to a Mitochondrial Eve. In Fantasy: How It Works, Attebery uses mitochondria metaphorically to explain how fantastic ideas evolve. Attebery describes fantastic mitochondria as “a cellular dynamo that lives within the tissues” of a story (91). He demonstrates how stories lead to retellings and elaborations that …

A Qualitative Description Of Graduate Students’ Perceived Decline In Physical Activity From Undergraduate School, Kristin M. Jett, Bryce T. Daniels, Max Brigance, Jessica L. Passarelli, Erin Howie

International Journal of Exercise Science

International Journal of Exercise Science 17(5): 1038-1055, 2024. Many university students, especially graduate students, are experiencing poor physical and psychological health. Thus, universities are initiating programs like Exercise is Medicine-On Campus (EIM-OC) to promote positive physical activity behavior to improve physical and mental health for primarily undergraduate university students. However, the influences on physical activity when transitioning from an undergraduate to a graduate student are unknown. To explore perceptions of if and how the physical activity levels of graduate students changed from their time as undergraduate students while considering environmental and lifestyle factors. METHODS: Using a qualitative, phenomenological research design, …


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 Aug 2024

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 …


‘A Stout Heart And A Good Blade’: An Examination And Reconsideration Of Éowyn In J.R.R. Tolkien’S The Lord Of The Rings, Angela Loving Aug 2024

‘A Stout Heart And A Good Blade’: An Examination And Reconsideration Of Éowyn In J.R.R. Tolkien’S The Lord Of The Rings, Angela Loving

Mythcon

For my paper I will examine and reconsider the character of Éowyn in The Lord of the Rings. I will look at the ways in which Tolkien uses dramatic elements and patterns from traditional literatures, including the Old English poem Beowulf and Shakespeare’s Macbeth, to tell an ancient tale anew, the tale of a dragon slain by an unlikely hero, in this case the Shield Maiden,Éowyn, and an even more unlikely assistant, a Hobbit named Merry. My process will focus on readings of the text, reflecting on ways Tolkien’s adaptations amplify female voice, choice, and agency. Éowyn enters in the …


Death, Soul, And Body In Tolkien’S Mythology: Perspectives On Athrabeth Finrod Ah Andreth, Chip Crane, Peter Grybauskas, Carl Hostetter Aug 2024

Death, Soul, And Body In Tolkien’S Mythology: Perspectives On Athrabeth Finrod Ah Andreth, Chip Crane, Peter Grybauskas, Carl Hostetter

Mythcon

The conversation between the elf Finrod Felagund and the human woman Andreth in Morgoth’s Ring volume 10 of The History of Middle-warth explores in depth the differences between elves and humans in Tolkien’s mythology. Their conversation touches, among other things, on the reason humans die and the relationship of soul to body in both. Panelists will share perspectives on the significance of this conversation in Tolkien’s mythology and his own metaphysics.


Current Lgbtq+ Aspects In Sf&F, David Lenander, Peg Kerr, David R. Slayton Aug 2024

Current Lgbtq+ Aspects In Sf&F, David Lenander, Peg Kerr, David R. Slayton

Mythcon

This panel was inspired by several things coming together. An awareness of Eleanor Arnason’s pioneering work in including LGBTQ+ characters in her novels, such as To the Resurrection Station, and some of her Lydia Duluth stories, and particularly in Ring of Swords and the other Hwarhath Stories, where this focus is a major theme. Then, there were the increasing number of books taking up these themes on the long and short lists for the Mythopoeic Fantasy Award, mirroring the changes that have occurred over the past few decades, so that early in our history these themes were not generally present, …


The Middle People Of Middle-Earth: Dwarven Displacement And Reconciliation In Tolkien’S Legendarium, Andrew Hickman Aug 2024

The Middle People Of Middle-Earth: Dwarven Displacement And Reconciliation In Tolkien’S Legendarium, Andrew Hickman

Mythcon

J.R.R. Tolkien’s beloved Dwarves evidence “middleness,” or a consistent state of being in flux or consistent change, as evidenced by their historical development, foreignness to other races, and displacement from their homes. The Dwarven race, from their first references in Tolkien’s works, are considered to be a race at odds with the other races of Ilúvatar. Tolkien’s Dwarves are initially seen as a politically neutral or an outright evil group, neither aligning themselves with followers of Manwë nor of Melkor. Additionally, they are described numerous times as more akin to the Orcish race than of the other Free Folk. While …


Searching For New Germplasm For The Year 2000 And Beyond, Rainer Schultze-Kraft, Warren M. Williams, John M. Keoghan Aug 2024

Searching For New Germplasm For The Year 2000 And Beyond, Rainer Schultze-Kraft, Warren M. Williams, John M. Keoghan

IGC Proceedings (1977-2023)

The likely germplasm needs for the next decades are discussed with major emphasis on tropical pastures, although many of the considerations apply also to temperate grasslands. The largest, and internationally most relevant, tropical-germplasm collections are held by CSIRO, CIAT and ILCA. Gerznplasm of <600 grass and <1500 legume species is available (with 6000-7000 and 26000-28000 accessions, respectively), representing 100-120 grass and 150-200 legume genera. Temperate germplasm collections are more numerous and hold larger numbers of accessions; they are, however, even more narrowly focused on very few genera (mainly four legume and eight grass genera). The numbers of species represented in the germplasm collections are only a fraction of considerably higher figures suggested in the literature as wild species with forage potential. Further collections to increase this fraction and to safeguard germplasm from genetic erosion and loss of biodiversity are warranted. International co-operation is suggested. Future germplasm needs are seen, in the tropics, mainly for low-input production systems on marginal, degraded lands and for agropastoral systems, and, in the temperate zone, for sustainable grasslands systems. Because of their dual­purpose characteristics legumes are expected to play a key role. It is suggested that the present collections might not contain a sufficiently broad base of germplasm with the required characteristics for the aforementioned production systems. Collection gaps can be identified only through thorough analyses of important genera and regions, based on a solid body of information that still needs to be assembled. A series of research topics is suggested to assist in future collection strategies, germplasm management and evaluation, and to create the basis for future breeding projects. However, expensive and long-term breeding programmes with tropical and many temperate forages are not encouraged for the near future unless the respective species and its natural variability are well enough known. The same applies to genetic manipulation via biotechnology. Implications arising from molecular biology are that new techniques are now available to improve understanding of genetic diversity and taxonomic relationships, and that the potential genetic resource now spans animals, micro-organisms and plants other than the target species. This wider genepool is also endangered and its conservation will rely on in situ preservation of the diverse ecosystems of which it is composed. The need of international support, co-operation and co-ordination regarding germplasm collection, related research and communication is emphasised. The creation of an JBPGR-sponsored, permanent, international working group on forages is suggested.


Establishing And Sharing Collections Of Valuable Global Resource, R Reid Aug 2024

Establishing And Sharing Collections Of Valuable Global Resource, R Reid

IGC Proceedings (1977-2023)

The conservation of forage plant genetic resources has attracted growing public and scientific interest in recent times. The number of genebanks has risen significantly with a concomitant increase in the total number of accessions. Competition for funds and some duplication of effort has led to an increasing need for co-operation between the curators if the full potential of the germplasm is to be realised. International organisations such as PAO, the mandated CGIAR Centres and IBPGR, have played a major role in establishing sustainable forage genetic resource programmes; and despite the restrictions of limited funding, have made some significant achievements in …

The C3 Plants And C4 Plants Growing On Semi-Arid Steppes Of North-East China, Yin Lijuan, Zhu Tingcheng Aug 2024

The C3 Plants And C4 Plants Growing On Semi-Arid Steppes Of North-East China, Yin Lijuan, Zhu Tingcheng

IGC Proceedings (1977-2023)

The north-east steppe of China is semi-arid. Forty-seven species of C3 plants and 53 species of C4 plants were defined. The C pathway of the 42 forage species among the total l 00 species is firstly identified by determining the ratio between RuBPCase/PEPCase (RIP) and observing the Kranz leaf anatomy. The abundance of C4 plants decreases with decreasing precipitation and the intensity of soil sandesation, and increases with lower latitude and increased soil salinisation.

Indigenous Populations Of Lolium Perenne L. Identification, Evaluation And Conservation, G Spatz, A Oetmann, C Paul

IGC Proceedings (1977-2023)

One hundred indigenous ryegrass populations were identified along 2 geographical gradients in Germany (west-east and north-south), Each population was sampled by collecting 180 tillers in 1991. The total 18 000 tillers were cultivated and will be examined as spaced plants (ex situ) in 1992 Nine selected populations were investigated in situ 1991. The results of the i11 situ investigations show high variability between and within the populations. The most valuable populations will be conserved as gene reserves within their environments (i11 situ). Promising material will in future be handed over to private breeders.
