Faculty, Staff and Student Publications

BACKGROUND: Few studies have previously assessed how pre-existing vitamin E status is associated with risk of tuberculosis (TB) disease progression.

OBJECTIVE: We evaluated the association between baseline plasma concentrations of 3 vitamin E isomers (α-tocopherol, γ-tocopherol, and δ-tocopherol) and TB disease risk.

METHODS: We conducted a case-control study nested within a longitudinal cohort of household contacts (HHCs) of pulmonary TB cases in Lima, Peru. We defined cases as HHCs who developed active TB disease ≥15 d after the diagnosis of the index patient, and we matched each case to 4 control cases who did not develop active TB based on …

A critical medical anthropological analysis is used …

Binational Farming Families Of Southern Appalachia And The Mexican Bajio, Mary Elizabeth W. Schmid

Theses and Dissertations--Anthropology

Over the last four decades, farming families throughout North America experienced significant transitions due, in part, to the implementation of the North American Free Trade Agreement. This multi-sited dissertation investigates the ways in which a network of binational (Mexican-American) families organize their small- to mid-scale farming enterprises, engage in global networks as food producers, and contribute to rural economies in the southeastern U.S. and the Mexican Bajío. To mitigate difficult transitions that came with the globalizing of agri-food markets, members of this extended family group created collaborative, kin-based arrangements to produce, distribute, and market fresh-market fruits and vegetables in the …

Late Pleistocene Adaptations In The Midsouth: The Paleoindian Occupation Of The Carson-Conn-Short Site And The Lower Tennessee River Valley, James Scott Jones

Theses and Dissertations--Anthropology

The Midsouth has long been known to be a locus of Paleoindian (13,200-10,000 yrs B.P.) populations. Paleoindian populations have generally been characterized as highly mobile hunter-gatherers with egalitarian social structure. Utilizing the theoretical lens of diversification and intensification of resource use, the Late Pleistocene adaptations of the region’s populations are examined from both a large scale or coarse grain perspective as well as more fine grain data from the site level. Previous models of Paleoindian adaptations are defined and tested in this study to determine the applicability of these models with new data. Coarse grain data are derived from lithic …

New Approaches To Selection System Design In Healthcare: The Practical And Theoretical Relevance Of A Modular Approach, Filip Lievens, Jan Corstjens

Research Collection Lee Kong Chian School Of Business

This chapter presents a modular approach to healthcare selection system design. Contrary to the traditional holistic view on selection procedures, a modular approach highlights the components underlying selection procedures. Our framework identifies seven key design components of selection procedures (The stimulus format, contextualization, stimulus presentation consistency, the response format, response evaluation consistency, information source, and instructions) and reviews studies in the healthcare selection literature that compared the effect of these components on key selection outcomes. A modular approach allows (1) gaining insights into how the different components underlying selection procedures affect selection outcomes and (2) drawing conceptual similarities between components …

Regulating Complacency: Human Limitations And Legal Efficacy, Steven L. Schwarcz

Faculty Scholarship

This Article examines how insights into limited human rationality can improve financial regulation. The Article identifies four categories of limitations—herd behavior, cognitive biases, overreliance on heuristics, and a proclivity to panic—that undermine the perfect-market regulatory assumptions that parties have full information and will act in their rational self-interest. The Article then analyzes how insights into these limitations can be used to correct resulting market failures. Requiring more robust disclosure and due diligence, for example, can help to reduce reliance on misleading information cascades that motivate herd behavior. Debiasing through law, such as requiring more specific, poignant, and concrete disclosure of …

Identification Of Genes And Metabolites Involved In Durian Durio Zibethinus Fruit Ripening, Pinnapat Pinsorn

Chulalongkorn University Theses and Dissertations (Chula ETD)

Durian (Durio zibethinus M.), a major economic fruit, actively produces infamous sulfur-containing compounds during ripening. However, sulfur metabolism which is important in this fruit is rarely investigated. In this study, the integration of metabolomics using CE-TOF/MS and transcriptomics using de novo RNA-seq assembly was performed to reveal metabolic changes involved in sulfur metabolism and chemical composition related to fruit quality. During ripening, the expression level of genes involved in sulfur metabolism is concurred with the reduced sulfate ion content in placenta and the up-accumulation of sulfur metabolism-related metabolites in pulps. It is noteworthy that durian pulps highly accumulate γ-glutamylcysteine (γ-EC) …

Chulalongkorn University Theses and Dissertations (Chula ETD)

Organic acids, which are benzoic acid, sorbic acid and propionic acid, are the most common preservatives used in foods and have been regulated the usage. Shrimp paste, called Kapi in Thai, is a fermented food that used in many Thai dishes. Owing to a complex matrix in shrimp paste, sample preparation is required to determine the amount of organic acid preservatives in shrimp paste. In this work, headspace solid-phase microextraction (HS-SPME) was developed for extraction of organic acid preservatives in shrimp pastes and analyzed by gas chromatography with flame ionization detector (GC-FID). The 85 µm polyacrylate coated fiber was used …

Image Super-Resolution Technique Using Deep Inception Based Residual Networks, Wazir Muhammad

Chulalongkorn University Theses and Dissertations (Chula ETD)

Recently, deep Convolutional Neural Networks (CNN) have achieved exceptional performance over the past few years, in the area of image processing and computer vision task, especially on single image super-resolution (SISR). It is an immensely challenging task and has multiple practical applications, such as medical image processing, satellite imaging, facial image enhancement, and compressed image improvement. However, the majority of the existing image super-resolution CNN-based methods have been developed by stacking an innumerable number of layers and blindly increasing the size of the network architecture. Conversely, this leads to an increase in the model sizes and higher computational complexities. Furthermore, …
