RESULTS: We identified 66 resources across 12 categories across the five conditions. The resources' varied eligibility criteria, application processes, and …

Extubation Decisions With Predictive Information For Mechanically Ventilated Patients In Icu, Guang Cheng, Jingui Xie, Zhichao Zheng, Haidong Luo, Oon Cheong Ooi

Research Collection Lee Kong Chian School Of Business

Weaning patients from mechanical ventilators is a crucial decision in intensive care units (ICUs), significantly affecting patient outcomes and the throughput of ICUs. This study aims to improve the current extubation protocols by incorporating predictive information on patient health conditions. We develop a discrete-time, finite-horizon Markov decision process with predictions of future state to support extubation decisions. We characterize the structure of the optimal policy and provide important insights into how predictive information can lead to different decision protocols. We demonstrate that adding predictive information is always beneficial, even if physicians place excessive trust in the predictions, as long as …

Information Production By Institutions And Information Extraction By Underwriters In Hybrid Ipo Auctions, Thomas J. Chemmanur, Pengfei Ma, Qianqian Yu

Research Collection Lee Kong Chian School Of Business

We analyze the informational properties of hybrid IPO auctions using a large and unique database of institutional bids from Chinese IPO auctions. We find strong evidence of information production by institutions about the intrinsic values of IPO firms and of underwriters extracting and using this information in IPO pricing. The IPO offer price is more sensitive to bids from institutions able to produce more precise information. In particular, the offer price is more sensitive to bids from domestic institutions, compared to bids from foreign institutions who likely have less knowledge or experience about the Chinese firms and financial market due …

Defending The Golden Fleece: A Study Of Disruption And Resilience In The Movement To Defund Public Libraries In Louisiana, Ciel Lane Quebedeaux

LSU New Orleans Theses and Dissertations

In this moment of societal change and institutional capture, public educational institutions have become sites of contention where national ideological and political debates are carried out in local school and library board meetings across the country. In Louisiana, the creation and expansion of a statewide conservative organization has led to the defunding of public libraries sparked by accusations of grooming and inappropriate programming. In response, local library defenders have created another statewide organization to share information and organizing strategies to combat disinformation campaigns propagated by conservative organizers at local and state levels. This qualitative study includes in-depth interviews with library …

Cotton, Paulo Eugenio Oliveira, Adriana Oliveira Machado, Jeferson Vizentin-Bugoni, Pedro Joaquim Bergamo

School of Biological and Marine Sciences

Functional traits determine interactions between plants and pollinators, and to increase pollination efficiency, many plants have evolved traits to attract specific pollinator groups. However, biogeographical setting may influence trait evolution and biotic interactions. For instance, plants pollinated by hummingbirds often have ornithophilous traits, that is, flowers with elongated corollas, dilute nectar and red colours, but—due to colonization history, depauperate biotas and unstable environmental conditions—it might be disadvantageous for species to rely on mutualistic partners with specific functional traits on oceanic islands. Hummingbird-visited plants on islands are thus expected to have fewer ornithophilous traits and be functionally less diverse in their …

This practice revealed a critical gap in preoperative education and multimodal pain management strategies, contributing to patient safety concerns and increased clinic workload.

Aim of the Project: The primary aim of the project was to improve pain control, reduce opioid reliance, and decrease postoperative pain-related follow-up calls by implementing a standardized, evidence-based …

Reducing Catheter-Associated Urinary Tract Infections In The Intensive Care Unit, Rosa Shiffman

All Doctor of Nursing Practice (DNP) Scholarly Projects

Problem: Catheter-associated urinary tract infections (CAUTIs) remain among the most common healthcare-associated infections in intensive care units (ICUs), contributing to increased morbidity, prolonged hospital stays, and elevated healthcare costs. Despite established prevention guidelines, inconsistent practices in catheter removal and gaps in daily necessity reviews persist. At the project site’s 24-bed ICU, the CAUTI rate was 1.9 per 1000 catheter days, which exceeds the national benchmark of 1.0. Gaps in consistent assessment of necessity and delays in removal contributed to an elevated infection risk.

Aim of the Project: This project aimed to reduce CAUTI rates in the ICU through evidence-based interventions …

Utilizing The Patient Health Questionnaire In A Family Practice Clinic To Enhance Clinical Benchmarks, Dorothy Akaeze

All Doctor of Nursing Practice (DNP) Scholarly Projects

Problem: About one-third of the 129 million chronically ill patients in the United States experience persistent depressive symptoms. Approximately 300 of 500 (60%) chronically ill patients treated at the project site each month show signs of depression, indicating a higher prevalence than the national rate of 33.33%. Despite the critical role of family practice in identifying and managing depression, many patients are not adequately screened, leading to missed opportunities for early diagnosis and treatment. The project site does not use the digitized PHQ screening tool to screen patients for depression. An analysis of patient charts revealed that, out of about …

Ecological disturbances are discrete events that alter or transform the physical, chemical, or biological characteristics of ecosystems. Disturbance can cause animal populations to decline and, according to the risk-disturbance hypothesis and population collapse framework, these declines can be predicted by declines in animal body condition. However, no research has empirically examined the general relationship between body condition and abundance, nor their relationship in response to disturbance. We used a combined dataset representing 33 studies and > 42,000 observations of 75 species from Australia, New Zealand, Spain and the United States of America to test predictions relating to the relationship between reptile …

Does External Labour Market Activeness Affect Agency Problem?, Yuyun Claudie Huang, Jamie Yixing Tong, Joey W. Yang

Research outputs 2022 to 2026

This study examines the relationship between external labour market and the agency problem. Exploiting the staggered recognition of the Inevitable Disclosure Doctrine (IDD) by US state courts to capture a drop in external labour market activeness, we examine whether and how the activeness of external labour market affects managers' empire building behaviour. We find that in IDD-recognising states, managers are less engaged in empire-building activity, thus reducing agency costs and improving firm performance. The effect is concentrated in managers with heightened career concern where their firms experience higher degrees of financial constraints or operate within an industry of more intense …

How Emotions In Online Reviews Affect Movie Sales: Evidence From Hollywood, Rahat Ullah, Muhammad Aftab Alam, Atya Zeb

Research outputs 2022 to 2026

Movies evoke strong human emotions that resonate in the content of online reviews, known as electronic word of mouth (eWOM). Existing literature suggests that positive content enhances, and negative content reduces movie sales, with negative content having a stronger effect. We demonstrate that there is a limit to the negative emotional content's impact on sales, beyond which it boosts sales. We extract positive and negative emotional content from 80 Hollywood movie reviews (N = 23,046) and empirically examine their influence on movie sales. Results indicate that for high eWOM volume, the effect of positive content increases progressively, while negative content …
