Medicaid Expansion Expectations, Deborah Farringer

Law Faculty Scholarship

Although financial stability in rural hospitals has been a relatively long-standing national problem, in the last decade, hospital closures and the incidence of highly distressed hospitals in rural areas have disproportionately impacted certain states. States that have not expanded their Medicaid programs under the Affordable Care Act, which implemented a program to extend additional federal support to cover adults living below 138% of the federal poverty line (referred to herein as “Medicaid Expansion”), are bearing the brunt of this crisis. Although the reason for hospital closures is multi-faceted and complex, health policy experts have consistently identified the lack of Medicaid …

Insider Trading Restrictions And Real Activities Earnings Management: International Evidence, Yuanto Kusnadi, Yuanto Kusnadi, Jiwei Wang, Yujie Wang

Research Collection School Of Accountancy

We examine the implications of insider trading restrictions on firms’ real activities earnings management in an international setting. Using a sample of 28 countries over the period from 1992 to 2007, we find evidence that is supportive of the substitution hypothesis, in that managers have incentives to substitute accruals earnings management for real activities earnings management. This effect is found to be more pronounced for firms in countries with more restrictive insider trading regulation. Our result is robust to alternative measures of real activities earnings management and insider trading restrictions, alternative sub-samples, alternative regression specifications, and controlling for endogeneity. In …

Contextualizing The Organizational Mindset, Joseph A. Carpini, Burak Oc

Research Collection Lee Kong Chian School Of Business

Although Schneider and Pulakos (2022, p. 2) call for scholars to adopt an “organizational mindset,” which includes “an increased organizational frame of reference on variables of interest,” the authors have overlooked the importance of contextualizing such a mindset. Contextualizing “entails linking observations to a set of relevant facts, events, or points of view that make possible research and theory that form part of a larger whole” (Rousseau & Fried, 2001, p. 1). Contextualizing is essential because it provides a common vernacular that facilitates the valid and reliable extension of the industrial-organizational (I-O) mindset to the study of organizational differences and …

Employer Image Within And Across Industries: Moving Beyond Assessing Points-Of-Relevance To Identifying Points-Of-Difference, Greet Van Hoye, Filip Lievens, Bert Weijters, Saartje Cromheecke

Research Collection Lee Kong Chian School Of Business

This study draws from brand positioning research to introduce the notions of points-of-relevance and points-of-difference to employer image research. Similar to prior research, this means that we start by investigating the relevant image attributes (points-of-relevance) that potential applicants use for judging organizations' attractiveness as an employer. However, we go beyond past research by examining whether the same points-of-relevance are used within and across industries. Next, we further extend current research by identifying which of the relevant image attributes also serve as points-of-difference for distinguishing between organizations and industries. The sample consisted of 24 organizations from 6 industries (total N = …

Distinctive Features Of Nonverbal Behavior And Mimicry In Application Interviews Through Data Analysis And Machine Learning, Sanne Rogiers, Elias Corneillie, Filip Lievens, Frederik Anseel, Peter Veelaert, Wilfried Philips

Research Collection Lee Kong Chian School Of Business

This paper reveals the characteristics and effects of nonverbal behavior and human mimicry in the context of application interviews. It discloses a novel analyzation method for psychological research by utilizing machine learning. In comparison to traditional manual data analysis, machine learning proves to be able to analyze the data more deeply and to discover connections in the data invisible to the human eye. The paper describes an experiment to measure and analyze the reactions of evaluators to job applicants who adopt specific behaviors: mimicry, suppress, immediacy and natural behavior. First, evaluation of the applicant qualifications by the interviewer reveals …

Corporate Actions And The Manipulation Of Retail Investors In China: An Analysis Of Stock Splits, Sheridan Titman, Chi Shen Wei, Bin Zhao

Research Collection Lee Kong Chian School Of Business

We identify a group of “suspicious” firms that use stock splits, perhaps along with other activities, to artificially inflate their share prices. Following the initiation of suspicious splits, share prices temporarily increase, and subsequently decline below their presplit levels. Using account level data from the Shanghai Stock Exchange, we find that small retail investors acquire shares in firms initiating suspicious splits, while more sophisticated investors accumulate positions before suspicious split announcements and sell in the postsplit period. We also find that insiders sell large blocks of shares and obtain loans using company stock as collateral around the initiation of suspicious …

Fractile Graphical Analysis In Finance: A New Perspective With Applications, Anil K. Bera, Aurobindo Ghosh

Research Collection Lee Kong Chian School Of Business

Fractile Graphical Analysis (FGA) was proposed by Prasanta Chandra Mahalanobis in 1961 as a method for comparing two distributions at two different points (of time or space) controlling for the rank of a covariate through fractile groups. We use bootstrap techniques to formalize the heuristic method used by Mahalanobis for approximating the standard error of the dependent variable using fractile graphs from two independently selected “interpenetrating network of subsamples.” We highlight the potential and revisit this underutilized technique of FGA with a historical perspective. We explore a new non-parametric regression method called Fractile Regression where we condition on the ranks …

To that end, we urge authors and reviewers to foster cross-fertilization from different theoretical and methodological silos, bolster robustness through multiple methods, and expand the domain of research to …

Dynamic S-Acylation Of The Er-Resident Protein Stromal Interaction Molecule 1 (Stim1) Is Required For Store-Operated Ca2+ Entry, Goutham Kodakandla, Savannah J West, Qiaochu Wang, Ritika Tewari, Michael X Zhu, Askar M Akimzhanov, Darren Boehning

Faculty, Staff and Student Publications

Many cell surface stimuli cause calcium release from endoplasmic reticulum (ER) stores to regulate cellular physiology. Upon ER calcium store depletion, the ER-resident protein stromal interaction molecule 1 (STIM1) physically interacts with plasma membrane protein Orai1 to induce calcium release-activated calcium (CRAC) currents that conduct calcium influx from the extracellular milieu. Although the physiological relevance of this process is well established, the mechanism supporting the assembly of these proteins is incompletely understood. Earlier we demonstrated a previously unknown post-translational modification of Orai1 with long-chain fatty acids, known as S-acylation. We found that S-acylation of Orai1 is dynamically regulated in a …

Invasive alien species (IAS) rank among the most significant drivers of species extinction and ecosystem degradation resulting in significant impacts on socio-economic development. The recent exponential spread of IAS in most of Africa is attributed to poor border biosecurity due to porous borders that have failed to prevent initial introductions. In addition, countries lack adequate information about potential invasions and have limited capacity to reduce the risk of invasions. Horizon scanning is an approach that prioritises the risks of potential IAS through rapid assessments. A group of 28 subject matter experts used an adapted methodology to assess 1700 potential IAS …

Development Of A Novel Pharmacophore Model To Screen Specific Inhibitors For The Serine-Threonine Protein Phosphatase Calcineurin, Abhisek Mukherjee, Karina Cuanalo-Contreras, Abha Sood, Claudio Soto

Faculty, Staff and Student Publications

Calcineurin (CaN) is a calcium/calmodulin-dependent serine/threonine phosphatase with a crucial role in cellular homeostasis. It is also the target of the Food and Drug Administration (FDA) approved immunosuppressant drugs FK506 and cyclosporine A. Recent work from our group and others indicated that an uncontrolled increase in CaN activity causes synaptic dysfunction and neuronal death in various models of neurodegenerative diseases associated with calcium dysregulation. Furthermore, pharmacological normalization of CaN activity can prevent disease progression in animal models. However, none of the FDA-approved CaN inhibitors bind CaN directly, leading to adverse side effects. The development of direct CaN inhibitors is required …

Axicabtagene ciloleucel (axi-cel) is an anti-CD19 chimeric antigen receptor (CAR) T cell therapy approved for relapsed/refractory large B cell lymphoma (LBCL) and has treatment with similar efficacy across conventional LBCL subtypes. Toward patient stratification, we assessed whether tumor immune contexture influenced clinical outcomes after axi-cel. We evaluated the tumor microenvironment (TME) of 135 pre-treatment and post-treatment tumor biopsies taken from 51 patients in the ZUMA-1 phase 2 trial. We uncovered dynamic patterns that occurred within 2 weeks after axi-cel. The biological associations among Immunoscore (quantification of tumor-infiltrating T cell density), Immunosign 21 (expression of pre-defined immune gene panel) and cell …

Oligometastatic Disease In The Liver: The Role Of Interventional Oncology, Ather Adnan, Rahul Anil Sheth, Alda Tam

Faculty, Staff and Student Publications

Oligometastatic disease represents a clinically discrete intermediate stage of cancer progression and is an expanding area of research. While surgical metastatectomy has been recognized for decades as an effective treatment option in select patients, options for metastasis-directed therapy have broadened in scope with advancements in the armamentarium of non- and minimally invasive modalities. Recent preclinical studies investigating the immunology surrounding liver metastases demonstrate treatment resistance to immunotherapy in affected patients and show how locoregional therapy has the ability to overcome this resistance. In this paper, we review advancements in our understanding of oligometastatic disease, metastasis-directed therapy, effect of liver metastasis …

An Empirical Model Of Proton Rbe Based On The Linear Correlation Between X-Ray And Proton Radiosensitivity, David B Flint, Chase E Ruff, Scott J Bright, Pablo Yepes, Qianxia Wang, Mandira Manandhar, Mariam Ben Kacem, Broderick X Turner, David K J Martinus, Simona F Shaitelman, Gabriel O Sawakuchi

Faculty, Staff and Student Publications

Background: Proton relative biological effectiveness (RBE) is known to depend on physical factors of the proton beam, such as its linear energy transfer (LET), as well as on cell-line specific biological factors, such as their ability to repair DNA damage. However, in a clinical setting, proton RBE is still considered to have a fixed value of 1.1 despite the existence of several empirical models that can predict proton RBE based on how a cell's survival curve (linear-quadratic model [LQM]) parameters α and β vary with the LET of the proton beam. Part of the hesitation to incorporate variable RBE models …

Lmo2 Expression Is Frequent In T-Lymphoblastic Leukemia And Correlates With Survival, Regardless Of T-Cell Stage, Kerri-Ann Latchmansingh, Xiaoqiong Wang, Ramiro E Verdun, Mario L Marques-Piubelli, Francisco Vega, M James You, Jennifer Chapman, Izidore S Lossos

Faculty, Staff and Student Publications

T- lymphoblastic leukemia/lymphoma (T-LL) is an aggressive malignancy of immature T-cells with poor overall survival (OS) and in need of new therapies. LIM-domain only 2 (LMO2) is a critical regulator of hematopoietic cell development that can be overexpressed in T-LL due to chromosomal abnormalities. Deregulated LMO2 expression contributes to T-LL development by inducing block of T-cell differentiation and continuous thymocyte self-renewal. However, LMO2 expression and its biologic significance in T-LL remain largely unknown. We analyzed LMO2 expression in 100 initial and follow-up biopsies of T-LL from 67 patients, including 31 (46%) early precursor T-cell (ETP)-ALL, 26 (39%) cortical and 10 …

Schwann Cells Induce Phenotypic Changes In Oral Cancer Cells, Maria Daniela Santi, Morgan Zhang, Elizabeth Salvo, Kesava Asam, Chi T Viet, Tongxin Xie, Moran Amit, Bradley Aouizerat, Yi Ye

Faculty, Staff and Student Publications

Head and neck cancer (HNC) is the seventh most common cancer worldwide, the majority being oral squamous cell carcinoma. Despite advances in cancer diagnosis and treatment, the survival rate of patients with HNC remains stagnant. The cancer-nerve interaction has been recognized as an important driver of cancer progression. Schwann cells, a type of peripheral glia, have been implicated in promoting cancer cell growth, migration, dispersion, and invasion into the nerve in many cancers. Here, it is demonstrated that the presence of Schwann cells makes oral cancer cells more aggressive by promoting their proliferation, extracellular matrix breakdown, and altering cell metabolism. …
