An Examination Of The International Baccalaureate’S Approaches To Learning As Humanizing, Leah Yates

Electronic Theses and Dissertations

The development of 21st-century skill frameworks characterized as being universal, transferrable, and future-facing are ubiquitous among international educational organizations (Suto & Eccles, 2014). The International Baccalaureate (IB) incorporates a similarly articulated universal, transferrable, and future-facing set of skills called the Approaches to Learning (ATL) in its four programmes (International Baccalaureate, 2022b). However, critiques of the IB as being Eurocentric and solely concerned with the development of learners for Western educational experiences calls for a critical examination of the ATL as promoting monocultural skills which are not contextual, personalized, or humanizing (Refai, 2020). This multiple-case study and document review utilized the …

Financialization And Price Volatility: An Empirical Analysis On Speculation In The Oil Market, Audry F. Oliveira Carnivale

Electronic Theses and Dissertations

Financialization has facilitated the trade of futures contracts because of deregulatory policies increasing speculation. Speculation has created a more fragile market inducing riskier investments and aggravating price volatility. Three post-Keynesian theories, the financial instability hypothesis, money manager capitalism and markup, explain how policy altering the banking structure has developed financialization from lax regulation. Previous research has emphasized supply and demand as the main determinants of oil price changes, but it’s important to consider how structural changes from policy stimulating a more financialized economy has impacted volatility. With Brent Crude oil price data and West Texas Intermediate (WTI) open interest and …

Investigating The Role Of Tetherin Protein In Multivesicular Bodies Fusions In Lung Cancer Cells, Md. Rakib Miah

Electronic Theses and Dissertations

Cells rely on the secretion of exosomes to communicate with one another and this process is potentially mediated by a protein called tetherin, which anchors exosomes to the cell surface to limit their spread. Tetherin protein has attracted a lot of attention because of its capacity to hinder the propagation of viruses by attaching virions to the surface of host cells. Treatment with interferon-alpha (IFNα) increases the production of tetherin, although it is not known how this affects tetherin localization and exosome-mediated communication. This thesis looks at how the expression of tetherin, which IFNα boosts, affects the dynamics of intercellular …
