Through The Arena: A Marxist Strategic-Relational Perspective On East Asian Regional Trade Architecture, John H. Limaldi

Journal of Critical Global Issues

This paper critically assesses the dominant regional trade architecture that impacts East Asia, focusing on the Trans-Pacific Partnership (TPP) and its U.S.-bastardized version, the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP). Using a strategic-relational approach grounded in Marxist theory, the paper examines how these agreements impact the relationship between the Capitalist State and Capital. It argues that international economic architecture in the neoliberal era produces state effects that weaken national sovereignty to the benefit of capital and the detriment of labor. The paper concludes with recommendations for a new regional trade architecture that prioritizes labor rights, democratic accountability, and …

Size Effect On The Shear Strength Of Reinforced Concrete Beams, Hind Jaber, Kaiss Sarsam, Bassman Muhammad

Engineering and Technology Journal

According to research, as the depth of a beam increases, the section's shear strength can be expected to decrease. The size effect is a phrase that has been used to describe this tendency. Testing of unreinforced specimens under shear has also shown that the shear strength might be lower than what is typically anticipated in the design. As a result, it is critical to comprehend the behavior of these structures, as they may be influenced by a size impact. Sixteen reinforced concrete beams of different rectangular cross-sections without stirrups were tested. The tested beams were simply supported made of high-strength …
