Employment With The Northwest Territories Aquatics Program: A Significant Life Event?, Sebastien Denize, Audrey R. Giles

International Journal of Aquatic Research and Education

For over 60 years, the Northwest Territories Aquatics Program (NWTAP) has employed university students from southern Canada with little to no exposure to northern Canada to run seasonal swimming pools and waterfronts in isolated northern communities. In this article, we examine the impact that working for this program had on nine former employees’ lives and whether or not working for the NWTAP could be categorized as a significant life experience. We used thematic analysis of the data from retrospective semi-structured interviews and open-ended questionnaires and identified four themes: (1) employment by the NWTAP enhanced the employees’ self-confidence, independence, and self-efficacy; …

The Diversity Of Norm Psychologies: A Challenge For The Law, Paul Sheldon Davies

William & Mary Law Review

Can we craft a coherent set of laws applicable to populations with deep cultural diversity? The full force of this question—call it the generalization challenge—has emerged recently thanks to advances in the sciences of the human, especially theories of neuroscience and psychology framed by theories of biological and especially cultural evolution. The goal of this Article is to describe enough of those advances to make clear the force of the challenge. The motivation is simple: as we endeavor to imagine the future of law in light of discoveries in neuroscience and related disciplines, being apprised of the generalization challenge may …

Ecopsychologists' Vital Importance In The Time Of Climate Crises, Nicole B. Auckerman Psyd

Antioch University Dissertations & Theses

Ecopsychology is a systems-based philosophy that expands the therapeutic lens to include client interactions with and perceptions of the natural environment as an integral element of well-being or pathology. Ecopsychology, known forward as EP, also looks at the pathology of our culture and what kind of diagnoses lead to practices that put our planet at risk. In recent decades, the field has amassed a substantial amount of empirical evidence supporting its effectiveness but remains largely underutilized. First generation EP suggested a cultural reordering shifting away from consumer culture and reordering our way of life. Second generation posits working within the …

TH2 cells and innate lymphoid cells 2 (ILC2) can stimulate tumor growth by secreting pro-tumorigenic cytokines such as interleukin-4 (IL-4), IL-5, and IL-13. However, the mechanisms by which type 2 immune cells traffic to the tumor microenvironment are unknown. Here, we show that oncogenic KrasG12D increases IL-33 expression in pancreatic ductal adenocarcinoma (PDAC) cells, which recruits and activates TH2 and ILC2 cells. Correspondingly, cancer-cell-specific deletion of IL-33 reduces TH2 and ILC2 recruitment and promotes tumor regression. Unexpectedly, IL-33 secretion is dependent on the intratumoral fungal mycobiome. Genetic deletion of IL-33 or anti-fungal treatment decreases TH2 and ILC2 infiltration and increases …

Gap Junction-Dependent And -Independent Functions Of Connexin43 In Biology, Yi Zhu

Children’s Nutrition Research Center Staff Publications

Simple Summary

Connexin43 is one of the 21 members of a large protein family that forms intercellular gap junction complexes. It plays a critical role in development by allowing two adjacent cells to exchange cellular content. Mouse deletion studies have demonstrated its critical roles in many organs, including cardiac muscle, blood vessels, bone, adipose tissue and more. However, as the most expressed and most studied connexin in the family, Connexin43 surprisingly shows many gap-junction-independent roles, spanning from the forming of hemichannels, to regulating membrane trafficking, to regulating mitochondrial function. Connexin43 is also unique in the family by forming many smaller …

Ahead Of His Time: Joseph Grinnell, Natural History, And Inclusion And Equity In Stem, David O. Ribble

Biology Faculty Research

Joseph Grinnell designed the Natural History of the Vertebrates (NHV) course at the Museum of Vertebrate Zoology, University of California at Berkeley, over 100 years ago and the course has changed little over these years. In this essay, I connect modern pedagogical and cognitive understandings of what we know leads to success among students to the course. This analysis reveals that the course continues to be successful because it has all the elements of a student-centered, active-learning class that leads to better cognitive gains, better retention, and importantly, proportionately better gains for students from underserved populations. This study will be …

Re-Assessing The Influence Of Particle-Hosted Sulphide Precipitation On The Marine Cadmium Cycle, Gregory F. De Souza, Derek Vance, Matthias Sieber, Tim M. Conway, Susan H. Little

Marine Science Faculty Publications

It has been inferred that the marine distributions of the micronutrient cadmium (Cd) and its stable isotope composition (expressed as δ¹¹⁴Cd) bear widespread and unambiguous evidence for loss of Cd from the shallow water column through the formation of particle-associated cadmium sulphide (CdS) in oxygen minimum zones (OMZs). In this review, we bring together elemental and isotopic datasets from the dissolved and particulate Cd pools in order to unravel the multiple, overlapping controls on the distribution of Cd and δ¹¹⁴Cd, and demonstrate that the global dataset challenges this view. By far the most important control on …

Serotonin's Proliferative Effects On Lung Cancer Cell Lines, Jessy K. Ntabo

Honors Undergraduate Theses

Serotonin has been widely explored in the brain. Recently, there have been new findings on how serotonin works in the periphery. Serotonin is introduced to the periphery by the enterochromaffin cells and metabolized by the liver and lung. Studies have shown that serotonin plays a role in controlling lung cancer. However, the mechanism by which it initiates tumor formation has not been fully explored. Cell viability was measured in several lung adenocarcinoma cell lines treated with serotonin to study this effect. In GFP-labelled cells, fluorescence intensity was measured for quantification of cell viability. Our data showed an overall increase in …

Honor Thyself, Alonzo O. Williams

Dance (MFA) Theses

The black male experience and identity in America are filled with complexity. We struggle to know ourselves. We work to see the way of love and the peace of an unviolated free spirit. We want to engage with ourselves with the highest degree of freedom and comfort, not to continue to question our identity in a life-threatening white patriarchal masculinity ideal. Honoring oneself from the lenses of the Reconstruction era of the United States is essential. Reconceptualizing this history explores the significance of emphasizing Reconstruction in my life as a black male to go through a process of self-discovery and …

The Role Of Human Dopamine Transporter Threonine 261 And Serine 262 In Amphetamine Regulation Of Transporter Function And Surface Expression, Sina Abdollahi

Theses and Dissertations

Amphetamine (AMPH) has been used clinically and recreationally around the world for years. A 2021 study reports a 67.5% rise in AMPH use from 2010-2017 across all fifty states. Study also shows that 30% of patients with AMPH-induced psychosis end up with primary psychosis over time. AMPH works by inhibiting monoamine (Norepinephrine (NE), Serotonin (5-HT), and Dopamine (DA) reuptake followed by triggering transporter mediated monoamine release and consequently increases monoamine concentrations in extracellular synaptic space. AMPH also works as a substrate for monoamine transporters, enters the neuron, and once its inside the neuron, it will prevent the storage of monoamines …

Mechanisms For Extracellular Matrix-Dependent Blood-Brain Barrier Dysfunction, Brian Adam Hoettels

Boise State University Theses and Dissertations

Dysfunction of the blood vessels that form the blood-brain barrier (BBB) is observed across various neurological disorders, including multiple sclerosis (MS). As barrier loss culminates in neuronal dysfunction and degeneration, a better understanding of the mechanisms underlying BBB dysfunction is needed.

Tight junctions are multiprotein complexes maintained by the endothelial cells lining the inner blood vessel wall to seal the intercellular space, and their disruption impairs BBB function. In my first chapter, I focus on how tight junctions are altered in CNS inflammatory demyelinating diseases (CNS-IDDs) like MS as BBB dysfunction is one of the earliest known stages in …

Host Genetics And Phenotype Associations Within The Bovine Rumen Microbiome, Waseem Abbas

Department of Animal Science: Dissertations, Theses, and Student Research

Rumen microbes have a symbiotic relationship with the host where the host provides a suitable environment and microbial fermentation fulfill nearly 70% of the energy needs of the host. Rumen microbes play a central role in host performance and health. To date, most rumen microbiome studies have focused on the influence of diet on microbial species composition. In addition to dietary factors, studies have suggested that host genetic markers could influence the colonization of gastrointestinal microbiota. However, our understanding of the host-microbiome interaction and how host phenotype is influenced by the rumen microbiome is limited. This dissertation demonstrates: (1) host …

USF Tampa Graduate Theses and Dissertations

Dry eye disease (DED) is a common condition that affects the eye's anterior surface due to tear deficiency or excessive evaporation. The lack of tears leads to dryness and initiation of an inflammatory response which can irritate the eye and interfere with daily activities. Current treatment depends mainly on artificial tears eye drops which offer temporary relief and require repetitive administration due to frequent blinking. Prescription medications are also available but need around three months to relieve dry eye symptoms. Quercetin is a flavonoid that has an anti-inflammatory and antioxidant effect. However, it suffers from low water solubility and low …

Knowledge About And Knowledge With: Contributions From Feminist Research To Knowledge Co-Production For Pastoral Systems, F. Ravera, María Fernández-Giménez, E. Oteros-Rozas

IGC Proceedings (1977-2023)

Globally, the gender dynamics of rangeland social-ecological systems have received scant attention. Further, research paradigms, methods and methodologies that leave little room for equitable engagement with research participants and genuine action-oriented research-practice partnerships dominate in pastoralist/rangeland studies. Our research is informed by a feminist philosophy of science and based on decolonial and feminist political ecology studies that focus on gendered science and knowledge production. Feminist research calls for reflection on who produces knowledge and how such knowledge is used and shared. Feminist practices such as reciprocity, care, and positionality, cultivate awareness of the power dynamics embedded in the research process …
