The Interpretive And Relational Work Of Financial Innovation: A Resemblance Of Assurance In Islamic Finance, Aaron Z. Pitluck Jan 2023

The Interpretive And Relational Work Of Financial Innovation: A Resemblance Of Assurance In Islamic Finance, Aaron Z. Pitluck

Faculty Publications – Sociology and Anthropology

What social forces shape the trajectory of novel, moralized forms of finance such as social finance, green finance, or Islamic banking and finance? More broadly, how do agents mobilize arguments and organize each other to create any form of financial innovation? This article addresses both questions by contributing an ethnography of a novel financial innovation pseudonymously named Sukuk Illumination, an internationally traded moral alternative to a corporate bond. This article’s findings both elaborate and subsume existing functionalist and critical explanations of financial innovation. The central argument is that we can better understand what causes financial innovation and the trajectory that …

A Machine Learning Predictive Model For The Extension Of Operation Time And The Operation Cost Overrun : A Case Study Of Vietnamese Bot-Ppp Transportation Projects, Pham Van Hoai

Chulalongkorn University Theses and Dissertations (Chula ETD)

Public-Private Partnership (PPP) projects in Vietnam's transportation sector are vital for infrastructure development but frequently encounter significant risk factors (RFs) during the operation phase. These RFs often lead to the extension of operation time (EOPT) and operation cost overruns (OPCO), undermining project success and investor returns. Despite the importance of the operation phase, most research has focused on the project feasibility and construction stages, with limited attention given to the operation phase. This research fills this gap by developing predictive models to manage the EOPT and OPCO caused by RFs during the operation phase of Build-Operate-Transfer (BOT) transportation projects in …

Mycobacterium Spp. Identification By Nanopore Technology, Samitanan Sunantawanit Jan 2023

Mycobacterium Spp. Identification By Nanopore Technology, Samitanan Sunantawanit

Chulalongkorn University Theses and Dissertations (Chula ETD)

Tuberculosis is caused by infection with Mycobacterium tuberculosis (MTB). Although TB and non-tuberculous mycobacteria (NTM) infection exhibit similar symptoms, their treatments differ significantly. NTM strains need a specific drug regimen and some NTM strains are resistant to anti-TB drugs. Hence, mycobacterial identification is crucial. At present, the culture-based technique is the gold standard in mycobacterium detection, but it is time-consuming (3-6 weeks). Here, this study aimed to develop mycobacterial amplicon-based nanopore sequencing (Myco-ANS) assay for the differentiation of eight reference strains of mycobacteria, as well as to assess the diagnostic accuracy of Myco-ANS compared with reference line probe assay for …
