Capacity Allocation And Revenue Sharing In Healthcare Alliances, Xiaoquan Gao, Jianpei Wen, Jie Song

Research Collection Lee Kong Chian School Of Business

This study investigates the operations of a healthcare alliance, where two types of independent hospitals [general hospitals (GHs) and community healthcare centers (CHCs)] collaborate in capacity allocation and revenue management to improve efficiency and revenue. Specifically, the GH allocates part of its capacity to establish a dedicated green channel for referral patients from the CHC based on a negotiated revenue sharing scheme. Generally, independent hospitals, like GHs and CHCs, in the healthcare delivery system provide complementary and substitute services due to the referral process and patients choice. Both service providers need each other, and their collaboration is very beneficial to …

Covid-19, Coronavirus, Wuhan Virus, Or China Virus? Understanding How To “Do No Harm" When Naming An Infectious Disease, Theodore C. Masters-Waage, Nilotpal Jha, Jochen Reb

Research Collection Lee Kong Chian School Of Business

When labeling an infectious disease, officially sanctioned scientific names, e.g., “H1N1 virus,” are recommended over place-specific names, e.g., “Spanish flu.” This is due to concerns from policymakers and the WHO that the latter might lead to unintended stigmatization. However, with little empirical support for such negative consequences, authorities might be focusing on limited resources on an overstated issue. This paper empirically investigates the impact of naming against the current backdrop of the 2019-2020 pandemic.

My Child’S Keeper: Child Vulnerability And Quality Of Life On Parental Stress And Grit, Abigail Armstrong

Master's Theses

There is a reciprocal relationship between parenting stress and child distress that has been well documented (e.g., Rechenberg, Grey & Sadler, 2017). These effects generalize to physical outcomes such that higher maternal depression has been associated with poorer child health-related quality of life (HRQOL; Jaser, Whittemore, Ambrosino, Lindemann, & Grey, 2008). In the same way that parental distress has been shown to affect the child, parental perceptions of child vulnerability in children with chronic illness has also been associated with negative outcomes, including child depressive symptoms (Mullins et al., 2004), increased health care use (Spurrier et al., 2000), and increased …

Development And Use Of An Environmental Dna Tool To Monitor Recovery Of The Critically Endangered Smalltooth Sawfish, Pristis Pectinata, In The Northwest Atlantic, Ryan N. Lehman

Master's Theses

The Critically Endangered Smalltooth Sawfish, Pristis pectinata, was once common in the tropical and subtropical waters of the Atlantic Ocean; however, following global declines in range and abundance over the past century, individuals were restricted to the waters of south and southwest Florida (SWFL) by about the 1980’s. Recently, public encounter reports have emerged in historically occupied habitats in United States waters, suggesting individuals are present in, or re-occupying, these areas, although the status of P. pectinata outside of SWFL is not currently well understood. Targeted environmental DNA (eDNA) surveys were chosen to assess the occurrence of P …

Exploring Dissociation As A Facilitator Of Suicide Risk Using Virtual Reality, Nicole Caulfield

Master's Theses

Research shows that suicidal behavior is not a result of a single cause or single event, but instead is an interaction of facilitators. One potential facilitator that needs further exploration is dissociation. Dissociation has been consistently linked to suicidal behavior, and treatment for dissociative disorders seem to be associated with a reduction of suicidal ideation and suicide attempts. Prior theories have posited that dissociation increases the possibility of a suicidal act because of intensified disconnect from the body. However, these theories do not indicate whether dissociation is a facilitator of suicide risk by increasing suicidal ideation, attempt behaviors, and capability …

Therefore, this study examined juvenile health through four markers: Linear Enamel Hypoplasia (LEH), a non-specific marker of health disruptions; Porotic Hyperostosis (PH), an indicator of anemia; and Periostitis, an indicator of infection. Some 131 individuals were evaluated using criteria developed by Steckel, Sciulli, and Rose (2002). The results were compared to Late Classic Copán (Storey, …

Effects Of Infection Of The Protist Parasite, Dermomycoides Sp., In Dusky Gopher Frog Tadpoles, Jaime Smith

Master's Theses

Infections of the protist parasite, Dermomycoides sp. are thought to have caused several years of low recruitment in the dusky gopher frog (Rana sevosa) populations. I evaluated the effects of density of the infective zoospores, host developmental stage, and tadpoles' ability to acquire resistance to Dermomycoides sp. on dusky gopher frog tadpoles. Tadpoles were exposed to zoospore densities of 0, 250, 500, and 750 zoospores/µL at Gosner stage 25, and we found no significant differences among treatments in tadpole mortality. In evaluating susceptibility by development stage, I exposed R. sevosa to 50 zoospores/µL as eggs, embryos, hatchlings, and …
