A Critical Analysis Of Identity Formation Amongst Closeted Filipino Youth Through Judith Butler's Gender Trouble, Nikky S. Garo, Samantha B. Cancino, Dhenissa B. Dugat, Patricia Suzanne J. Mahawatta, Julianne Margarette C. Ocampo, Jared Emeric G. Sanchez

Social Sciences and Development Review

Filipino society is often regarded as being pervasively conservative and a stickler for heteronormativity, putting young people identifying within the queer umbrella under significant pressure to conform to traditional gender and sexual norms. This environment fosters a dual performative identity, where closeted individuals present a “cisnormative” front in the face of traditionally restrictive spaces while exploring and expressing a more authentic identity within supportive communities. Queer theory, which challenges binary conceptions of gender and sexuality, frames this exploration by validating the fluidity of non-traditional labels as tools for self-expression, even if only within specific contexts. Feminist theory adds further depth …

Reconceptualizing Political Socialization In The Philippines, Nathan Mishael O. Go

Social Sciences and Development Review

Political socialization is a lifelong process of learning about political beliefs, attitudes, and motivations. Studies that have attempted to uncover political socialization in the Philippines have associated socialization with political participation and political cynicism; such an association imposes limits on how political socialization is viewed. Thus, this paper attempts to reconceptualize political socialization in the Philippines by introducing nuances and developments in the field of political participation, political socialization, and Philippine society.

Michigan Tech Publications

Underwater images often suffer from severe color distortion, low contrast, and reduced visibility, motivating the widespread use of image enhancement as a preprocessing step for downstream computer vision tasks. However, recent studies have questioned whether enhancement actually improves object detection performance. In this work, we conduct a comprehensive and rigorous evaluation of nine state-of-the-art enhancement methods and their interactions with modern object detectors. We propose a unified evaluation framework that integrates (1) a distribution-level quality assessment using a composite quality index (Q-index), (2) a fine-grained per-image detection protocol based on COCO-style mAP, and (3) a mixed-set upper-bound analysis that quantifies …

A Rare Culprit Or An Elusive Culprit In Disguise? Unraveling Wild-Type Attr Cardiac Amyloidosis In Heart Failure With Reduced Ejection Fraction, Jose J. Loayza Pintado, Taiwo Ajani, Daniela Hernandez, Everardo Cobos

School of Medicine Publications

Cardiac amyloidosis (CA) is a rare disorder caused by the deposition of abnormal proteins called amyloid in the myocardium, leading to dysfunction. The 2 most common forms of amyloidosis are AL (light chain) and ATTR (transthyretin). Diagnosing amyloidosis is challenging, especially in its early stages, due to its nonspecific symptoms and overlap with other conditions. Recent studies suggest that the incidence of wild-type transthyretin amyloidosis is rising, likely due to improved diagnostic techniques and an aging population. We present the case of a 72-year-old male with lower extremity edema, progressive shortness of breath, and worsening renal function. He had a …
