Responsible Hedge Funds, Hao Liang, Lin Sun, Song Wee Melvyn Teo

Research Collection Lee Kong Chian School Of Business

Hedge funds that endorse the United Nations Principles for Responsible Investment (PRI) underperform other hedge funds after adjusting for risk but attract greater investor flows, accumulate more assets, and harvest greater fee revenues. Consistent with an agency explanation, the underperformance is driven by PRI signatories with low environmental, social, and governance (ESG) exposures and is greater for hedge funds with poor incentive alignment. To address endogeneity, we exploit regulatory reforms that enhance stewardship and show that the ESG exposure and relative performance of signatory funds improve post reforms. Our findings suggest that some hedge funds endorse responsible investment to pander …

Is There A Strategic Organization In The Behavioral Theory Of The Firm? Looking Back And Looking Forward, Henrich R. Greve, Cyndi Man Zhang

Research Collection Lee Kong Chian School Of Business

In the 20 years of Strategic Organization, how well has knowledge drawn from the behavioral theory of the firm contributed to the field of strategy? We see progress both in the pages of SO! and elsewhere in the field of strategy, but this progress has been held back by divisions between strategy and organization theory in what theories should predict, what mechanisms are preferable predictors, and what outcomes are of interest. Despite these divisions, the last few years have seen particularly rapid progress, turning the behavioral theory of the firm into one of multiple organization theory sources of strategy knowledge. …

Can Big Data Cure Risk Selection In Healthcare Capitation Program? A Game Theoretical Analysis, Zhaowei She, Turgay Ayer, Daniel Montanera

Research Collection Lee Kong Chian School Of Business

Problem definition: This paper analyzes a market design problem in Medicare Advantage (MA), the largest risk-adjusted capitation payment program in the U.S. healthcare market. Evidence exists that the current MA capitation payment program unintentionally incentivizes health plans to cherry pick profitable patient types, which is referred to as “risk selection”. However, the root causes of the risk selection are not comprehensively understood, which we study in this paper. Academic / Practical Relevance: The existing literature primarily attributes the observed risk selection in MA market to data limitations and low explanatory power (e.g. low R2) of the current risk adjustment design. …

The Road To A Human-Centred Digital Society: Opportunities, Challenges And Responsibilities For Humans In The Age Of Machines, David De Cremer, Devesh Narayanan, Andreas Deppeler, Mahak Nagpal, Jack Mcguire

Research Collection Lee Kong Chian School Of Business

The growing adoption of intelligent technologies has brought us to a crossroad. The creators of intelligent technologies are acquiring the power to influence a wide variety of outcomes that are important to human end-users. In doing so, those same intelligent technologies are being used to undermine and even actively harm the interests of those same end-users. In the absence of a recalibration, we are almost certainly headed down a path wherein intelligent technologies will primarily serve the interests of developers and owners of technology rather than humankind at large. In an attempt to push for such a recalibration, we present …

Faculty, Staff and Student Publications

Medical management of heart failure (HF) has evolved and has achieved significant survival benefits, resulting in highly complex medication regimens. Complex medication regimens create challenges for older adults, including nonadherence and increased adverse drug events, especially associated with cognitive impairment, physical limitations, or lack of social support. However, the association between medication complexity and patients' health outcomes among older adults with HF is unclear. The purpose of this review is to address how the complexity of HF medications has been assessed in the literature and what clinical outcomes are associated with medication regimen complexity in HF. Further, we aimed to …

There are long-standing concerns that people experiencing homelessness may not recover well if left unsupported after a hospital stay. This study reports on a study investigating the cost-effectiveness of three different 'in patient care coordination and discharge planning' configurations for adults experiencing homelessness who are discharged from hospitals in England. The first configuration provided a clinical and housing in-reach service during acute care and discharge coordination but with no 'step-down' care. The second configuration provided clinical and housing in-reach, discharge coordination and 'step-down' intermediate care. The third configuration consisted of housing support workers providing in-reach and discharge coordination as well …

Investigation Of Murine Host Sex As A Biological Variable In Epithelial Barrier Function And Muscle Contractility In Human Intestinal Organoids, Brooke T Beanland, Eoin P Mcneill, David J Sequeira, Hasen Xue, Noah F Shroyer, Allison L Speer

Faculty, Staff and Student Publications

Intestinal failure (IF) occurs when intestinal surface area or function is not sufficient to support digestion and nutrient absorption. Human intestinal organoid (HIO)-derived tissue-engineered intestine is a potential cure for IF. Research to date has demonstrated successful HIO transplantation (tHIO) into mice with significant in vivo maturation. An area lacking in the literature is exploration of murine host sex as a biological variable (SABV) in tHIO function. In this study, we investigate murine host SABV in tHIO epithelial barrier function and muscle contractility. HIOs were generated in vitro and transplanted into nonobese diabetic, severe combined immunodeficiency gamma chain deficient male …

Faculty, Staff and Student Publications

PURPOSE: Adequate pulmonary function is important for patients undergoing surgical resection of esophageal cancer, especially those that received neoadjuvant therapy. However, it is unknown if pre-operative radiation affects pulmonary function differently compared to chemotherapy. The purpose of this study was to compare changes in pulmonary function between patients undergoing minimally invasive esophagectomy (MIE) who received neoadjuvant chemotherapy or chemoradiotherapy.

METHODS: Between March 2017 and March 2018, esophageal cancer patients requiring neoadjuvant therapy were prospectively enrolled and randomly assigned to receive chemotherapy (CT) or chemoradiotherapy (CRT) before MIE. All patients received pulmonary function testing before and after the neoadjuvant therapy. Changes …

“Racing-Stripe” Modification Of Radial Forearm Free Flap: Technique And Experience (704 Consecutive Cases), Emmanuel G Melissinos, Erik S Marques

Faculty, Staff and Student Publications

The radial forearm fasciocutaneous free flap (RFFF) has proven to be a versatile and reliable tool for the reconstructive microsurgeon when addressing soft-tissue defects. A significant drawback of the traditional RFFF is related to donor site morbidity and wound healing complications, especially when coverage of sizable defects is planned. The authors describe the "racing-stripe" modification of the RFFF (RS-RFFF) that involves harvesting a large segment of the deep forearm fascia with a narrow strip of skin overlying the radial vessels, thus allowing primary closure of the donor site.

METHODS: Retrospective chart review was conducted of a single surgeon's (E.G.M.) experience …

A Novel Microgrid Fault Detection And Classification Method Using Maximal Overlap Discrete Wavelet Packet Transform And An Augmented Lagrangian Particle Swarm Optimization-Support Vector Machine, Masoud Ahmadipour, Muhammad Murtadha Othman, Rui Bo, Zainal Salam, Hussein Mohammed Ridha, Kamrul Hasan

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, an intelligent method for fault detection and classification for a microgrid (MG) was proposed. The idea was based on the combination of three computational tools: signal processing using the maximal overlap discrete wavelet packet transform (MODWPT), parameter optimization by the augmented Lagrangian particle swarm optimization (ALPSO), and machine learning using the support vector machine (SVM). The MODWPT was applied to preprocess half cycle of the post-fault current samples measured at both ends of feeders. The wavelet coefficients derived from the MODWPT were statistically evaluated using the mean, standard deviation, energy, skewness, kurtosis, logarithmic energy entropy, max, min, …

Severe mental illnesses (SMI), including major depressive (MDD), bipolar (BD), and schizophrenia spectrum (SSD) disorders have multifactorial risk factors and capturing their complex etiopathophysiology in an individual remains challenging. Regional vulnerability index (RVI) was used to measure individual's brain‐wide similarity to the expected SMI patterns derived from meta‐analytical studies. It is analogous to polygenic risk scores (PRS) that measure individual's similarity to genome‐wide patterns in SMI. We hypothesized that RVI is an intermediary phenotype between genome and symptoms and is sensitive to both genetic and environmental risks for SMI. UK Biobank sample of N = 17,053/19,265 M/F (age = 64.8 …

Faculty, Staff and Student Publications

As part of efforts to combat the Covid-19 pandemic and decrease the high transmissibility of the new coronavirus, SARS-CoV-2, effective inactivation strategies, such as UV-C decontamination technologies, can be reliably disseminated and well-studied. The present study investigated the susceptibility of a high viral load of SARS-CoV-2 in filtering facepiece respirators (FFR) N95, surgical mask, cotton fabric mask and N95 straps under three different doses of UV-C, applying both real-time PCR (qPCR) and plaque formation assays to quantify viral load reduction and virus infectivity, respectively. The results show that more than 95% of the amount of SARS-CoV-2 RNA could be reduced …

Same Day Discharge Following Elective, Minimally Invasive, Colorectal Surgery : A Review Of Enhanced Recovery Protocols And Early Outcomes By The Sages Colorectal Surgical Committee With Recommendations Regarding Patient Selection, Remote Monitoring, And Successful Implementation, Elisabeth C Mclemore, Lawrence Lee, Traci L Hedrick, Laila Rashidi, Erik P Askenasy, Daniel Popowich, Patricia Sylla

Faculty, Staff and Student Publications

BACKGROUND: As enhanced recovery programs (ERPs) have continued to evolve, the length of hospitalization (LOS) following elective minimally invasive colorectal surgery has continued to decline. Further refinements in multimodal perioperative pain management strategies have resulted in reduced opioid consumption. The interest in ambulatory colectomy has dramatically accelerated during the COVID-19 pandemic. Severe restrictions in hospital capacity and fear of COVID transmission forced surgical teams to rethink strategies to further reduce length of inpatient stay.

METHODS: Members of the SAGES Colorectal Surgery Committee began reviewing the emergence of SDD protocols and early publications for SDD in 2019. The authors met at …

Assessing Naming Errors Using An Automated Machine Learning Approach, Tatiana T Schnur, Chia-Ming Lei

Faculty, Staff and Student Publications

OBJECTIVE: After left hemisphere stroke, 20%-50% of people experience language deficits, including difficulties in naming. Naming errors that are semantically related to the intended target (e.g., producing "violin" for picture HARP) indicate a potential impairment in accessing knowledge of word forms and their meanings. Understanding the cause of naming impairments is crucial to better modeling of language production as well as for tailoring individualized rehabilitation. However, evaluation of naming errors is typically by subjective and laborious dichotomous classification. As a result, these evaluations do not capture the degree of semantic similarity and are susceptible to lower interrater reliability because of …
