Founder Worship, Effective Altruism, And Corporate Governance, Jennifer S. Fan, Xuan-Thao Nguyen Jan 2025

Founder Worship, Effective Altruism, And Corporate Governance, Jennifer S. Fan, Xuan-Thao Nguyen

Law Faculty Research and Publications

Founders are the heart of any startup. Oftentimes, they are given considerable latitude in managing a company, particularly if they are hailed as a visionary founder in a pathbreaking new industry. Additionally, it is assumed that underpinning their actions is the desire to do good. Unfortunately, sometimes this leads to what we term founder worship where the promise of the founder and the innovation may lead to perverse outcomes because too much control is ceded to the founder and there is a lack (or sometimes complete absence of) corporate governance. When unlimited control is coupled with "do gooderism," which in …


Geopolitical Changes And Futures Of Ccamlr, Nengye Liu Jan 2025

Geopolitical Changes And Futures Of Ccamlr, Nengye Liu

Research Collection Yong Pung How School Of Law

The Convention on the Conservation of Antarctic Marine Living Resources (CAMLR Convention) was negotiated in the late 1970s in the shadow of the Soviet Union’s expanding interest in Antarctic krill fisheries. The development of a management regime for the krill fishery in the remote Southern Ocean vividly reflects geopolitical changes of the world at that time. The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) is similarly being affected by geopolitical forces from the wider international system today. This chapter therefore first reviews the historical background for the establishment of the CCAMLR. It then provides an overview of …

Aspen Stands Enrich Bird Communities Following A Wildfire In A Montane, Mixed Conifer Forest, Cody Q. Lane Jan 2025

Aspen Stands Enrich Bird Communities Following A Wildfire In A Montane, Mixed Conifer Forest, Cody Q. Lane

Graduate Student Theses, Dissertations, & Professional Papers

Fire is a major ecological force in most terrestrial systems, but the responses of animal communities to fire vary markedly across ecosystems due to variability in fire regimes and vegetation communities. Quaking aspen (Populus tremuloides) is unique within coniferous forests of western North America for its ability to regenerate following wildfire via vegetative resprouting. As managers employ techniques to restore fire regimes and conserve declining aspen forests, it becomes important to understand how aspen alters postfire communities. Our objectives were to (1) assess how aspen interacted with fire severity and years since fire to influence avian species and …

Exploring The Potential For Cynophagy, Working Dogs, And Village Dogs At Housepit 54, Daniel O. Nohren

Graduate Student Theses, Dissertations, & Professional Papers

Several field seasons at the Bridge River Archaeological Site have recovered a vast faunal assemblage subject of numerous archaeological and genetic investigations, several of which have focused on potential roles of domestic dogs (Canis familiaris). In order to examine the highly fractured nature of the Housepit 54 canid assemblage, the calculation of a fracture freshness index was performed which created quantitative units of measure useful in the comparison of bone fracture taphonomy over time and across taxonomic groups. This method has been employed specifically to investigate the potential for exploitation of within-bone nutrients among both a sample of …


Investigating Algal Response To Scouring Flow And Nutrient Interactions In The Clark Fork River, Montana, Hannah E. Adkins Jan 2025

Investigating Algal Response To Scouring Flow And Nutrient Interactions In The Clark Fork River, Montana, Hannah E. Adkins

Graduate Student Theses, Dissertations, & Professional Papers

Algal communities play a vital role in aquatic ecosystems, but excessive growth can degrade water quality, disrupt ecosystem function, and hinder beneficial uses (Banish, 2017; Davie, 2012; Wang et al., 2007; Wurtsbaugh et al., 2019). Nutrient enrichment, particularly elevated nitrogen and phosphorus concentrations, is a well-established driver of algal proliferation in lentic systems. However, these nutrient–algae relationships are less predictable in lotic systems, where the dynamic effects of flow can modify or obscure these patterns (Bennet et al., 2017; Biggs and Close, 1989; Dodds et al., 2002). The Clark Fork River in western Montana has long struggled with nuisance algal …


Positive Allosteric Modulation Of Glun1/Glun3 Nmda Receptors, Mia Ruth Johns Jan 2025

Positive Allosteric Modulation Of Glun1/Glun3 Nmda Receptors, Mia Ruth Johns

Graduate Student Theses, Dissertations, & Professional Papers

N-methyl-D-aspartate (NMDA) receptors are ionotropic glutamate receptors that mediate excitatory neurotransmission in the central nervous system (CNS) where they play critical roles in normal and pathological brain functions and neurodevelopment. While the glutamate/glycineactivated GluN2-containing NMDA receptors (GluN1/GluN2) have been extensively studied, the physiological roles and pharmacology of glycine-activated GluN3-containing receptors (GluN1/GluN3) remain less understood. Although GluN1/GluN3 receptors exhibit unique functional properties and play distinct roles in neuronal development and synapse maturation, studies of their precise roles in neurophysiology and circuit function are impeded by limited availability of GluN3-selective pharmacological tools. This study describes UCM-A86, a novel GluN3-selective positive allosteric …


In The Clear: Timber Harvest Informs Elk Summer Nutrition And Resource Selection In A Densely Forested Landscape, Trevor C. Weeks Jan 2025

In The Clear: Timber Harvest Informs Elk Summer Nutrition And Resource Selection In A Densely Forested Landscape, Trevor C. Weeks

Graduate Student Theses, Dissertations, & Professional Papers

As wildlife and habitats face unprecedented challenges in the form of landscape conversion, shifting disturbance regimes, and climate change, it becomes increasingly important for land and wildlife managers to find avenues for collaboration as they seek to maintain habitat to support robust wildlife populations. Timber harvest may provide one such avenue for collaboration. It has been shown to increase the quality and quantity of ungulate nutritional resources by reverting stands to early successional stages. Additionally, timber harvest may allow for a more precise application of such effects, as managers choose where and how to harvest timber. However, the exact effects …


Social, Ecological, And Anthropogenic Drivers Of Gray Wolf Vital Rates In Yellowstone National Park, Brenna Jo Cassidy Jan 2025

Social, Ecological, And Anthropogenic Drivers Of Gray Wolf Vital Rates In Yellowstone National Park, Brenna Jo Cassidy

Graduate Student Theses, Dissertations, & Professional Papers

Populations of animals can be regulated by many factors, including food availability, anthropogenic influences, and social dynamics. Survival of adults and juveniles is one mechanism of population regulation, and these life stages can be influenced by different ecological pressures. In this dissertation, I investigate the ecological, anthropogenic, and social drivers of transboundary gray wolf (Canis lupus) vital rates in and around Yellowstone National Park. First, I evaluate the effect of variable harvest pressure on wolf survival and test whether anthropogenic mortality is compensatory or additive. Theory predicts that under densitydependent conditions, anthropogenic mortality should be offset by a corresponding reduction …


Causes And Consecuences Of Gene Expression Divergence In The Rodent Placenta, Luis Fernando Rodriguez Caro Jan 2025

Causes And Consecuences Of Gene Expression Divergence In The Rodent Placenta, Luis Fernando Rodriguez Caro

Graduate Student Theses, Dissertations, & Professional Papers

Understanding the origin and diversification of reproductive traits is a central goal in evolutionary biology. In mammals, the placenta represents a key evolutionary innovation that reshaped developmental strategies and enabled the ecological success of the clade. Yet despite its importance, the genetic mechanisms and selective pressures driving placental evolution remain poorly understood, due in part to methodological challenges and the limited phylogenetic and genomic scope of prior studies. This dissertation research addresses these gaps by integrating comparative genomics, transcriptomics, and new analytical tools to investigate placental gene regulation across closely related rodent species. Chapter one presents an extensive comparison of …

Cross-cultural studies are crucial for investigating the cultural variability and universality of cognitive developmental processes. However, cross-cultural assessment tools in cognition across languages and communities are limited. In this article, we describe a gaze-following task designed to measure basic social cognition across individuals, ages, and communities (the Task for Assessing iNdividual differences in Gaze understanding-Open-Cross-Cultural; TANGO-CC). The task was developed and psychometrically assessed in one cultural setting and, with input of local collaborators, adapted for cross-cultural data collection. Minimal language demands and the web-app implementation allow fast and easy contextual adaptations to each community. TANGO-CC captures individual- and community-level variation …

School of Psychology

Psychological studies on close relationships have often overlooked cultural diversity, dynamic processes, and potentially universal principles that shape intimate partnerships. To address the limited generalizability of previous research and advance our understanding of romantic love experiences, mate preferences, and physical attractiveness, we conducted a large-scale cross-cultural survey study on these topics. A total of 404 researchers collected data in 45 languages from April to August 2021, involving 117,293 participants from 175 countries. Aside from standard demographic questions, the survey included valuable information on variables relevant to romantic relationships: intimate, passionate, and committed love within romantic relationships, physical-attractiveness enhancing behaviors, gender …


Strabismus And Amblyopia Disrupt Spatial Perception But Not The Fidelity Of Cortical Maps In Human Primary Visual Cortex, D. Schluppeck, D. Arnoldussen, Z. Hussain, J. Besle, S. T. Francis, P. V. Mcgraw Jan 2025

Strabismus And Amblyopia Disrupt Spatial Perception But Not The Fidelity Of Cortical Maps In Human Primary Visual Cortex, D. Schluppeck, D. Arnoldussen, Z. Hussain, J. Besle, S. T. Francis, P. V. Mcgraw

School of Psychology

Amblyopia is a common disorder of spatial vision and is frequently associated with the presence of anisometropia, strabismus, or both, during visual development. For highly visible stimuli, subjects with strabismic amblyopia often report marked spatial distortions, but the neural basis of this supra-threshold deficit is not well understood. Here, we used a combination of behavioural measurements and visual field mapping with high spatial-resolution functional magnetic resonance imaging (fMRI) at 7 T to assess perceptual distortions in 12 participants with strabismic amblyopia and 9 control subjects. We measured both behavioural and cortical visual field maps monocularly through each eye. Although amblyopic …

Understanding The Role Of Pluralistic Ignorance In Biodiversity Conservation: A Research Agenda, Sandra J. Geiger, Hirotaka Imada, Carya Maharja, Nattavudh Powdthavee, Valeria Vitale, Lei Zhang, Claudio D. Rosa, Zenith N. C. Delabrida, Kristian S. Nielsen, Franz Essl, Mathew P. White

School of Psychology

Most people believe that biodiversity loss is human-caused, yet they may not realize how many others share this belief. Such collective misperceptions—known as pluralistic ignorance—may hinder individual and system changes required to address biodiversity loss. At the same time, reducing pluralistic ignorance may promote positive change. In this Perspective, we provide a brief overview of existing work on pluralistic ignorance about environmental topics and propose an agenda for impactful pluralistic ignorance research in the biodiversity domain. We highlight several research gaps and offer recommendations, including (a) investigating different forms of pluralistic ignorance, (b) improving our understanding of consequences and determinants, …


“Being Away From Everything”: Exploring The Importance Of Access To Nature For Individuals Living With Chronic Low Back Pain, Alexander Smith, Kayleigh Wyles, Patricia Schofield, Sam Hughes Jan 2025

“Being Away From Everything”: Exploring The Importance Of Access To Nature For Individuals Living With Chronic Low Back Pain, Alexander Smith, Kayleigh Wyles, Patricia Schofield, Sam Hughes

School of Psychology

Chronic low back pain is a persistent and debilitating condition, and therapeutic outcomes in the long term are generally poor. There is growing evidence to support the ineffectiveness of ‘one-size-fits-all’ pharmacological approaches to pain management. To that end, alternative non-pharmacological therapies such as green social prescribing and time spent in nature are gaining popularity. But it is imperative to understand to what extent these potential interventions are viable by gaining a deeper insight into the lived experiences of the chronic low back pain community. The present qualitative cross-sectional study employed ten semi-structured interviews (9 women, M age = 50.1, M …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Background

Doublecortin-like kinase 1 (DCLK1) isoforms play distinct roles in the progression of gastrointestinal cancers. For the first time ever, the current study aimed to generate DCLK1-S-specific monoclonal antibodies (mAbs) to evaluate the clinical value of DCLK1-S (short isoform) in gastric cancer (GC).

Materials and methods

Mice were immunized with a unique 7-mer synthetic peptide of DCLK1-S conjugated with keyhole limpet hemocyanin (KLH). Immunoreactivity of hybridomas and mAbs was determined by ELISA assays and immunohistochemistry (IHC). DCLK1-S expression in two GC cell lines was assessed by flow cytometry. After characterization, the expression pattern of DCLK1-S was investigated in different histological …


Acute, Low-Grade Inflammation Elevates White Matter Sensitivity To Ischaemia, Alex Mellor Jan 2025

Acute, Low-Grade Inflammation Elevates White Matter Sensitivity To Ischaemia, Alex Mellor

Peninsula Medical School Theses

Ischaemic brain injuries, including ischaemic stroke, are highly prevalent neurological diseases. Acute, low-grade inflammation, often resulting from peripheral infection, has emerged as a risk factor. White matter axons, and their supporting glia, are susceptible to both ischaemic and neuroinflammatory injury. The mechanisms behind ischaemic injury in white matter are well established. However, the white matter response to acute, low-grade inflammation, and how this can interact with co-morbidities such as cerebral ischaemia, are yet to be examined. This thesis evaluated the response of white matter to acute, low-grade inflammation and the downstream effects this had on its sensitivity to ischaemia. Here, …


Targeting Aldehyde Dehydrogenases In Nf2-Null Meningioma And Schwannoma, Libby Williams Jan 2025

Targeting Aldehyde Dehydrogenases In Nf2-Null Meningioma And Schwannoma, Libby Williams

Peninsula Medical School Theses

Meningioma and schwannoma are tumours of the brain and nervous system that are frequently driven by loss or mutation of the gene NF2, which encodes the tumour suppressor protein Merlin. Dysregulated Hippo pathway signalling, caused by NF2 loss, drives overexpression of aldehyde dehydrogenase 1A1 (ALDH1A1) in NF2-null schwannoma. High expression of ALDH1A1, and the related isoform ALDH1A3 have been identified as markers of cancer stem cell activity and have been correlated with poor prognosis and chemoresistance in several cancers. This project aims to clarify the role ofaldehyde dehydrogenase (ALDH) enzymes in meningioma tumours and evaluate their potential as future therapeutic …


Targeting Mertk On Tumour Cells And Macrophages: A Potential Intervention For Sporadic And Nf2-Related Meningioma And Schwannoma Tumours, Kevin Herrera Keane Jan 2025

Targeting Mertk On Tumour Cells And Macrophages: A Potential Intervention For Sporadic And Nf2-Related Meningioma And Schwannoma Tumours, Kevin Herrera Keane

Peninsula Medical School Theses

Although schwannomas and meningiomas are generally benign and slow-growing, the mass effect of either tumour within the nervous system causes life-altering symptoms. Individuals with NF2-related schwannomatosis may develop schwannomas and meningiomas, increasing tumour burden. The primary treatment for large or symptomatic schwannomas and meningiomas is surgical resection, which may not be suitable in cases involving tumours located near sensitive neuroanatomy or clinically vulnerable individuals. Not all schwannomas and meningiomas respond to alternative targeted treatments such as stereotactic radiosurgery or the vascular endothelial growth factor inhibitor bevacizumab. The main objective of this thesis was to investigate targeting of the receptor tyrosine …

School of Biological and Marine Sciences

Global calls for greater ocean protection have sparked renewed interest in very large marine protected areas (VLMPAs, >100,000 km2) to achieve management targets; however, their conservation value is debated. We assessed the suitability of a VLMPA (640,000 km2) in the Indian Ocean for capturing the movements of resident mobile marine megafauna. We found that 95% of foraging, breeding and/or locally migrating individuals occurred within the VLMPA despite variable habitat use; adult hawksbill turtles (Eretmochelys imbricata, n = 22, 6124 tracking days) foraged on mesophotic banks (>30 m depth), reef manta rays (Mobula alfredi, n = …


Temperature-Driven Plasticity In Boldness, Its Predictability And Learning In The Beadlet Anemone, Actinia Equina, Samantha Simpson, Dunia Gonzales, Mark Briffa Jan 2025

Temperature-Driven Plasticity In Boldness, Its Predictability And Learning In The Beadlet Anemone, Actinia Equina, Samantha Simpson, Dunia Gonzales, Mark Briffa

School of Biological and Marine Sciences

Variation in ambient temperature is for poikilothermic animals a key driver of behavioural variation because of its multiplicative effects on metabolic rate. Apart from the fundamental environmental source of behavioural variation, understanding the effects of temperature is also important in the context of predicted climate change scenarios. In particular, behavioural responses to extreme temperature fluctuation could represent maladaptive responses to rapidly changing environments. However, behavioural responses to moderate temperature fluctuations, within ranges that are routinely experienced, likely represent adaptive plasticity. Recent studies have addressed this question within an animal personality framework, which can quantify the effects of temperature regime across …

Effects Of Dietary L-Tryptophan On Growth Performance, Feed Utilization, And Protein Metabolism In Nile Tilapia (Oreochromis Niloticus), Israt Mishu, Lindee Mason, Ahmed Mustafa

Mansoura Veterinary Medical Journal

This research examines the impact of dietary L-tryptophan supplementation on growth performance, feed efficiency, and protein metabolism in Nile tilapia (Oreochromis niloticus) under stress and non-stress settings. This experiment evaluated essential growth metrics, encompassing weight gain, length gain, specific growth rate, feed conversion ratio, and protein energy retention. Nile tilapia were categorized into four experimental groups: a control group on a commercial diet, a control group supplemented with L-tryptophan (0.33%/kg feed), a stress-induced group receiving cortisol (0.02%/kg feed), and a stress-induced group receiving both cortisol (0.02%/kg feed) and L-tryptophan supplementation (0.33%/kg feed). The findings indicated that Ltryptophan supplementation significantly enhanced …
