Migrant Labour Protection In Asean, In What Way Does Ilo Matter?, Dwi Ardhanariswari Sundrijo, Dhanny Safitri Dec 2023

Migrant Labour Protection In Asean, In What Way Does Ilo Matter?, Dwi Ardhanariswari Sundrijo, Dhanny Safitri

Global: Jurnal Politik Internasional

Despite the importance of labour migration in Southeast Asia, the mechanism of migrant workers protection in the region is still lacking. Because of that, cases show that often the undocumented and/or the low-skilled workers receive inappropriate treatment in the host countries. In certain cases, they were treated as second-class citizens – this is despite the work that they do. To address these issues, ASEAN has conducted a series of dialog forums and issued various agreements. In doing so, ASEAN have been involving different key stakeholders working on the issue, including international organizations, regional and national civil society organizations, and employers’ …

Department of Psychology: Faculty Publications

Background Sexual violence (SV) is a significant, global public health problem, particularly among young adults. Promising interventions exist, including prosocial bystander intervention programs that train bystanders to intervene in situations at-risk for SV. However, these programs suffer from critical weaknesses: (1) they do not address the proximal effect of alcohol use on bystander decision-making and (2) they rely on self-report measures to evaluate outcomes. To overcome these limitations, we integrate new content specific to alcohol use within the context of prosocial bystander intervention into an existing, evidence-based program, RealConsent1.0. The resulting program, RealConsent2.0, aims to facilitate bystander behavior …

Void Formation And Mortality During Liquid Composite Molding, Jared Michael Turner Dec 2023

Void Formation And Mortality During Liquid Composite Molding, Jared Michael Turner

Theses and Dissertations

Within the high-performance composite manufacturing industry, there exists a need to improve the reliability of LCM (Liquid Composite Molding) manufacturing processes in producing composite parts that better approach the quality and consistency of pre-impregnated composite tapes that are cured in autoclaves with cost being a driving factor of this need. One obstacle to that end is the phenomenon of void formation during the LCM infusion processes. The formation of these voids through different mechanisms leads to composite parts with lower mechanical properties and consistency than their pre-impregnated autoclave cure counterparts. The objective of this research is to investigate the different …

The State Of Active Blended Learning In Construction Education: Reviewing Research And Current Perspectives, Shandon Miles Gubler Dec 2023

The State Of Active Blended Learning In Construction Education: Reviewing Research And Current Perspectives, Shandon Miles Gubler

Theses and Dissertations

STEM educators have shown a particular interest in active blended learning. Construction management education, a discipline within STEM education, has naturally considered blended instruction to engage students in the learning process. Documented efforts of construction management educators implementing blended instruction have mostly been recorded in conference proceedings. These recorded efforts often take the form of anecdotal case studies—a current review of how construction management faculty are implementing blended instruction and active learning in their blended courses was not found. In this study, we reviewed the literature for active blended instruction in construction management education. We surveyed construction management faculty about …


Linking Individual Behavior With Physiology To Understand Complex Life Histories, Doreen Cabrera Dec 2023

Linking Individual Behavior With Physiology To Understand Complex Life Histories, Doreen Cabrera

Theses and Dissertations

Life history strategies encompass a suite of co-evolved traits crucial for ensuring an individual's fitness, often evolving from trade-offs between traits competing for the same resources. Adult male crayfish in the Cambaridae family undergo seasonal morphological changes linked to reproductive status, a process called cyclic dimorphism. In this dissertation, we attempt to understand how cyclic dimorphism evolved in non-native northern crayfish (Faxonius virilis). First, in Chapter 1, we review empirical studies that have assessed animal personality across developmental periods. The results show that personality traits tend to be stable within life stages but not across developmental events. In Chapter 2, …

Quantifying Non-Muscle Myosin 2 Filament Dynamics, Melissa Ann Quintanilla Dec 2023

Quantifying Non-Muscle Myosin 2 Filament Dynamics, Melissa Ann Quintanilla

Dissertations

Non-muscle myosin 2 is a motor protein that, when assembled into filaments, works on the actin cytoskeleton to produce contractile forces within cells. This type of myosin dynamically assembles within cells to exert forces necessary for a wide variety of functions including cell division, migration, and multicellular movement. The ability to dynamically assemble contractile networks, and the ability to control the assembly and placement of these myosin filaments in both space and time, is therefore required throughout cell physiology. We used a suite of dynamic, quantitative imaging approaches to identify deterministic factors that drive myosin filament appearance and amplification as …


The Experience Of Teaching Disengaged Students In Stem: Examined Through The Lens Of The Abc Engagement Framework, William Randall Hjorth Dec 2023

The Experience Of Teaching Disengaged Students In Stem: Examined Through The Lens Of The Abc Engagement Framework, William Randall Hjorth

Theses and Dissertations

Young people today are increasingly disengaged from their education. Studies indicate that of all school subjects, American students struggle to engage in STEM subjects more than others. For decades, we have known that student engagement/disengagement impacts teachers. Researchers have also claimed that engagement/disengagement can be described as a construct made up of affective, behavioral, and cognitive dimensions (ABC). However, we do not understand how teachers experience student disengagement in these three areas. At a crucial time in education, investigation into the experiences of teachers with disengaged students is needed to uncover insights which may help us understand how teachers interpret …

Faculty Publications

Introduction Health disparities exist at every step of the HIV care continuum (HCC) among racial/ethnic minority population. Such racial/ethnic disparities may have significantly delayed the progress in HCC in the Southern US states that are strongly represented among geographic focus areas in the 2019 federal initiative titled 'Ending the HIV Epidemic: A Plan for America'. However, limited efforts have been made to quantify the long-term spatiotemporal variations of HCC disparities and their contributing factors over time, particularly in the context of COVID-19 pandemic. This project aims to identify the spatiotemporal patterns of racial disparities of each HCC outcome and then …


A Path To Full Citizenship: The Impact Of The Civil Rights Movement On The Creation Of Title I Schools Through The Elementary And Secondary Education Act Of 1965, Edwin Ryan Dec 2023

A Path To Full Citizenship: The Impact Of The Civil Rights Movement On The Creation Of Title I Schools Through The Elementary And Secondary Education Act Of 1965, Edwin Ryan

Washington Semester Program

Studies of the Civil Rights Movement commonly include events like Brown v. Board of Education, the Civil Rights Act of 1964, the Voting Rights Act of 1965, sit-ins, bus boycotts, and the Freedom Riders. The creation of Title I schools through the Elementary and Secondary Education Act (ESEA) in 1965 to serve "disadvantaged" students also was a major move in a broader attempt to undo systematic Black poverty. As part of his War on Poverty in the formation of a "Great Society," President Lyndon Johnson and his administration proposed drastic increases for federal involvement in the funding of public school …

In-Depth Geochemical Analysis Of Turbidite-Associated Shales Of The Pindos Basin, Greece, Jonathon Michael Sevy Dec 2023

In-Depth Geochemical Analysis Of Turbidite-Associated Shales Of The Pindos Basin, Greece, Jonathon Michael Sevy

Theses and Dissertations

Detailed geochemical analysis of the turbidite-associated shales of the Cretaceous Katafito Formation, Greece, reveals important details regarding the paleoenvironment, paleoproductivity, and regional tectonics of the Pindos Basin. The Katafito Formation was deposited along an active margin at the early onset of closure of the Tethys Sea in the Pindos sub-basin. While careful studies of the coarse clastic component of turbidites are common, this study consisted of a detailed geochemical characterization of the fine-grained portions, which helped reveal paleoenvironmental information about the basin. This study combined organic and inorganic geochemistry utilizing elemental, mineralogical, and organic chemical signatures from fine-grained turbidite-associated sediments …

Oncogenic KRAS (KRAS*) contributes to many cancer hallmarks. In colorectal cancer, KRAS* suppresses antitumor immunity to promote tumor invasion and metastasis. Here, we uncovered that KRAS* transforms the phenotype of carcinoma-associated fibroblasts (CAF) into lipid-laden CAFs, promoting angiogenesis and tumor progression. Mechanistically, KRAS* activates the transcription factor CP2 (TFCP2) that upregulates the expression of the proadipogenic factors BMP4 and WNT5B, triggering the transformation of CAFs into lipid-rich CAFs. These lipid-rich CAFs, in turn, produce VEGFA to spur angiogenesis. In KRAS*-driven colorectal cancer mouse models, genetic or pharmacologic neutralization of TFCP2 reduced lipid-rich CAFs, lessened tumor angiogenesis, and improved overall survival. …

Expression Of Pfkfb Isoenzymes During In Vitro Differentiation Of Mouse Embryonic Stem Cells Into Insulin-Producing Cells, Sai̇me Güzel, Abdullah Yalçin, Yunus Gürpinar, Sabi̇re Güler

Turkish Journal of Medical Sciences

Background/aim: Type 1 diabetes mellitus (T1DM) is caused by the autoimmune-mediated destruction of insulin-producing cells (IPCs) and still has no effective cure. Better understanding of the molecular mechanisms involved in the differentiation of embryonic stem cells (ESCs) into IPCs may help us improve the therapeutic strategies for treating T1DM. 6-phosphofructo-2-kinase/fructose-2,6- bisphosphatases (Pfkfb1-4) are key regulators of glucose metabolism. Although Pfkfb3 has been shown to be required for the growth of early differentiated mouse ESCs (mESCs), more studies are needed to further assess the roles of Pfkfb isoenzymes in embryonic development and differentiation, particularly into specific cell types. In this study, …

INTRODUCTION: The clinical benefit of the anti-CTLA-4 monoclonal antibody (mAb) ipilimumab has been well established but limited by immune-related adverse events, especially when ipilimumab is used in combination with anti-PD-(L)1 mAb therapy. To overcome these limitations, we have developed XTX101, a tumor-activated, Fc-enhanced anti-CTLA-4 mAb.

METHODS: XTX101 consists of an anti-human CTLA-4 mAb covalently linked to masking peptides that block the complementarity-determining regions, thereby minimizing the mAb binding to CTLA-4. The masking peptides are designed to be released by proteases that are typically dysregulated within the tumor microenvironment (TME), resulting in activation of XTX101 intratumorally. Mutations within the Fc region …

UNLABELLED: The tumor microenvironment (TME) restricts antitumor CD8+ T-cell function and immunotherapy responses. Cancer cells compromise the metabolic fitness of CD8+ T cells within the TME, but the mechanisms are largely unknown. Here we demonstrate that one-carbon (1C) metabolism is enhanced in T cells in an antigen-specific manner. Therapeutic supplementation of 1C metabolism using formate enhances CD8+ T-cell fitness and antitumor efficacy of PD-1 blockade in B16-OVA tumors. Formate supplementation drives transcriptional alterations in CD8+ T-cell metabolism and increases gene signatures for cellular proliferation and activation. Combined formate and anti-PD-1 therapy increases tumor-infiltrating CD8+ T cells, which are essential for …
