Over four months, four care homes each received two JfA devices (one cat and dog), and four homes received care as usual (intervention and control group). Psychometrics were …

Community Campus As Threshold: A Space Of Dialogue For Academia And The Community, R Brown, P Warwick, Zoe Latham, Rachel Manning, Sebastian Stevens

School of Art, Design and Architecture

This paper explores an argument for community-situated spaces of encounter – acting as thresholds – between community and academia, through which: learning can be enhanced; a greater sense of identity and efficacy can be fostered; and a defined agency can be enabled. This proposition prioritises a dialogic relationship in a shared ground of agency and discourse, whose potential is reinforced through a rediscovery of the local arising from the Covid pandemic. The rediscovery of the local has pushed civic-minded universities pre-existing interrogation of their community-based learning practice in the context of marginalised communities; a key challenge is how to foster …

This study aimed to identify whether the current understanding of latitudinal and bathymetric gradients in α-diversity (species richness) apply to seamount ecosystems, as well as ascertaining whether identifiable trends were present in seamount β-diversity along a bathymetric gradient.LocationExclusive Economic Zones of Saint Helena, Ascension Island and Tristan da Cunha, spanning 8–40°S in the South Atlantic.TaxonSeamount megabenthic communities.MethodsImages from 39 transects, collected between 250 and 950 m, were used to …

Deoxyribose Phosphate Aldolase Is Required For Development Of Hematopoietic Stem Cells In The Zebrafish Embryo, Anubhav Thapaliya, Sanyam Patel, Teerth Y. Patel, Sivam J. Bhatt, Erich W. Damm

UROP Posters

Hematopoietic stem cells (HSCs) are an integral part of modern biomedical research because they are precursors to all blood cell lineages in vertebrates. Further understanding of hematopoietic development will allow for improvements in the success of therapeutic bone marrow transplantation; which is a crucial treatment in management of both malignant and non-malignant blood disorders. Although HSC transplantation is curative for many blood disorders, finding compatible donors is difficult due to a need for immunologic compatibility. Consequently, recent research efforts have been directed towards generating HSCs for the patient, from the patient themselves through the directed differentiation of induced pluripotent stem …

Individual And Collective Behaviour Of Fish Subject To Differing Risk-Level Treatments With A Sympatric Predator, Alexander D.M. Wilson, Timothy M. Schaerf, Ashley J.W. Ward

School of Biological and Marine Sciences

The ability to adapt behaviour according to context is vital to the success of many organisms, particularly when it comes to mitigating risk, across time and space, in unpredictable environments. While many studies have examined the role of predation threat in shaping behaviour, very few have quantitatively investigated prey responses across different elements of perceived risk or ecological contexts. Here, we present a detailed analysis of how mosquitofish (Gambusia holbrooki) adapt their individual and collective behaviour in five experimental treatments designed to replicate different core elements of predator threat. As risk increased, within and across treatments, fish decreased movements across …

Overcoming barriers to knowledge sharing between land managers and researchers is a critical cross-sector strategy for engaging and mitigating or adapting to drought. Here we describe the establishment and functioning of the Pacific Drought Knowledge Exchange (PDKE), which provides users with easier access to: (1) sector- and geography-specific climate information; (2) better and more comprehensive information; (3) improved technical assistance; and (4) a more collaborative information-transfer environment through participation in …

Applying Landscape Fragmentation Analysis To Icescape Environments: Potential Impacts For The Pacific Walrus (Odobenus Rosmarus Divergens), Anthony Himmelberger, K E. Frey, Florencia Sangermano

Geography

Sea-ice cover across the Arctic has declined rapidly over the past several decades owing to amplified climate warming. The Pacific walrus (Odobenus rosmarus divergens) relies on sea-ice floes in the St. Lawrence Island (SLI) and Wainwright regions of the Bering and Chukchi seas surrounding Alaska as a platform for rest, feeding and reproduction. Lower concentrations of thick ice floes are generally associated with earlier seasonal fragmentation and shorter annual persistence of sea-ice cover, potentially affecting the life history of the Pacific walrus. In this study, 24 Landsat satellite images were classified into thick ice, thin ice or open water to …

Behavior And Chemical Signals As Markers Of Colony Identification In Argentine Ants (Linepithema Humile), Stephanie A. Rohrbach

College of Graduate Studies: Theses & Dissertations

Argentine ants, Linepithema humile, are a highly successful invasive species around the globe and are especially prominent in states such as California and the southeastern United States. L.humile have a unique form of unicoloniality, called “supercolonies”. L. humile can detect colonymates through scent markers in their outer cuticle. With these chemical markers, ants will exhibit high aggression if they smell different from one another. In our study, we performed aggression assays among ten different nest sites and analyzed their CHCs through gas chromatography mass spectrometry, or GC-MS, analysis. For our behavior results, while within-nest interactions displayed low aggression as …

Felon Re-Enfranchisement And The Problem Of “Lost” Rights, Josh Feinzig

Faculty Scholarship

By conditioning the restoration of political rights on financial repayment, states have prevented hundreds of thousands of citizens with felony convictions from participating politically—profoundly altering the shape of the American electorate. Courts have upheld the practice by treating restoration as an exercise of legislative grace to nonmembers of the political community. Critics argue that the practice conditions political participation on wealth status and is therefore subject to heightened review.

This Essay traces the disagreement back to an overlooked first-order question: how should the juridical status of a disenfranchised citizen’s “lost” rights be understood? The conventional position assumes that disenfranchisement casts …

Microvascular Consequences Of Engineered Nanomaterial Inhalation Exposure And Subsequent Reproductive Outcomes, Krista Lee Garner

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nano-titanium dioxide (nano-TiO₂) is a commonly utilized engineered nanomaterial found ubiquitously in consumer products. While benefits of ENM utilization in are undeniable, nanoparticle inhalation has been linked to cardiovascular consequences and altered microvascular responses. Given these outcomes, it is important to explore vulnerable timepoints, such as gestation, as robust vascular adaptations are essential for maternofetal health.

The first aim of this dissertation was to assess myogenic responsiveness following maternal nano-TiO₂ inhalation. Fetal aortic responses were evaluated on gestational day (GD) 20 to assess how exposure may impact the F1 generation. Myogenic responsiveness within the uterine radial arteries …

Tetramerization Of Stat5 Has Opposing Roles In Governing Autoimmune Pathogenesis, Kelly Lynn Monaghan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Signal transducers and activators of transcription 5 (STAT5A and STAT5B) are members of the STAT protein family. STAT5 plays a critical role in mediating cellular responses following cytokine stimulation. Critical STAT5 signaling is achieved following functional dimerization, which occurs via SH2 domain interactions. The binding of two STAT5 dimers to tandemly linked TTCN₃GAA γ-interferon-activated sequence (GAS) motifs and N-terminal domain interactions, facilitates functional tetramerization. The biological role of STAT5 tetramers has been investigated using the Stat5a-Stat5b N-domain double knock-in (DKI) mouse strain, in which STAT5 tetramers cannot be formed due to substitutions in critical amino acid …
