Occupational Stress In Psychiatric Nurses And The Impact Of Self-Care Activities, Jacqueline Lowe Sep 2022

Occupational Stress In Psychiatric Nurses And The Impact Of Self-Care Activities, Jacqueline Lowe

Doctor of Nursing Practice Projects

Background

The nursing profession is an extremely stressful occupation. Psychiatric nurses face many of the general stressors that are inherent within the profession as well as unique challenges in taking care of psychiatric patients. Prolonged exposure to stress can impact the quality of the nurses' lives as well as the quality of patient care. Engagement in self-care activities can promote the well-being of psychiatric nurses.

Purpose

To investigate the level of occupational stress in psychiatric nurses and offer them a guided six-week program on self-care activities. This intervention was measured for any change in the level of occupational stress that …


Medicaid Expansion Expectations, Deborah Farringer Sep 2022

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 …


Logics' Shift And Depletion Of Innovation: A Multi-Level Study Of Agile Use In A Multinational Telco Company, Maria Carmela Annosi, Elisa Mattarelli, Evelyn Micelotta, Antonella Martini Sep 2022

Logics' Shift And Depletion Of Innovation: A Multi-Level Study Of Agile Use In A Multinational Telco Company, Maria Carmela Annosi, Elisa Mattarelli, Evelyn Micelotta, Antonella Martini

Faculty Research, Scholarly, and Creative Activity

The use of Agile practices is typically associated to a wide array of benefits for organizations. This paper extends growing research on the ‘dark’ side of Agile by investigating the depletion of innovation in a large telco company following the large-scale implementation of Agile in R&D units. Our qualitative study reveals a shift in the organizational logics underpinning new product development, from a “navigating through unchartered waters” to a “putting out fires” logic. We tracked the change in key components of logics (goals of teams, source of legitimacy of team members and support and control systems) and explained the multi-level …


Uncovering The Value Of Blockchain Applications In The World Of Finance, Qiang Cheng Sep 2022

Uncovering The Value Of Blockchain Applications In The World Of Finance, Qiang Cheng

Research Collection School Of Accountancy

This article discusses the benefits of using blockchain in the context of asset-backed security (ABS) issuance: reducing information asymmetry between issuers and investors, reducing yield spread of ABS, disciplining credit rating agencies, increasing the quality of underlying assets, and reducing issuers’ risk exposure. Such benefits should apply to other blockchain applications in the world of finance.


Tax Challenges In Debt Financing Involving Digital Tokens, Vincent Ooi Sep 2022

Tax Challenges In Debt Financing Involving Digital Tokens, Vincent Ooi

Research Collection Yong Pung How School Of Law

When digital tokens are used in debt finance, one cannot assume that the same orthodox tax treatment will apply. The highly specific nature of tax provisions means that they may apply very differently once digital tokens rather than fiat currency are involved. Through a case study of Singapore law, this article shows that if debt finance transactions involving digital tokens are not carefully structured, there may be severe tax consequences, including the inability to deduct borrowing costs or benefit from common tax incentives, and the possible incurrence of additional tax liabilities. This article submits that, under Singapore tax law, it …


Insider Trading Restrictions And Real Activities Earnings Management: International Evidence, Yuanto Kusnadi, Yuanto Kusnadi, Jiwei Wang, Yujie Wang Sep 2022

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 …


Out Of The Trap: Conversion Funnel Business Model, Customer Switching Costs, And Industry Profitability, Niloofar Abolfathi, Andrea Fosfuri, Simone Santamaria Sep 2022

Out Of The Trap: Conversion Funnel Business Model, Customer Switching Costs, And Industry Profitability, Niloofar Abolfathi, Andrea Fosfuri, Simone Santamaria

Research Collection Lee Kong Chian School Of Business

Research Summary: Across many industries, firms employ a conversion funnel business model to attract customers with basic and affordable products, generate lock-in, and then sell them more advanced and expensive products. We argue that this business model, coupled with high customer switching costs, results in a market outcome characterized by aggressive pricing and reduced profits. A sudden reduction in customer switching costs disrupts the conversion funnel and can eventually increase industrywide prices and profitability, an outcome that contradicts conventional wisdom in strategy research. We develop a stylized model to formalize our ideas and provide supportive evidence using a difference-in-differences methodology …


Contextualizing The Organizational Mindset, Joseph A. Carpini, Burak Oc Sep 2022

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 …


Overnight Returns, Daytime Reversals, And Future Stock Returns, Ferhat Akbas, Ekkehart Boehmer, Chao Jiang, Paul D. Koch Sep 2022

Overnight Returns, Daytime Reversals, And Future Stock Returns, Ferhat Akbas, Ekkehart Boehmer, Chao Jiang, Paul D. Koch

Research Collection Lee Kong Chian School Of Business

A higher frequency of positive overnight returns followed by negative trading day reversals during a month suggests a more intense daily tug of war between opposing investor clienteles, who are likely composed of noise traders overnight and arbitrageurs during the day. We show that a more intense daily tug of war predicts higher future returns in the cross section. Additional tests support the conclusion that, in a more intense tug of war, daytime arbitrageurs are more likely to discount the possibility that positive news arrives overnight and thus overcorrect the persistent upward overnight price pressure.


What You See Is What You Get? Measuring Companies' Projected Employer Image Attributes Via Companies' Employment Webpages, Christian P. Theurer, Philipp Schapers, Andranik Tumasjan, Isabell M. Welpe, Filip Lievens Sep 2022

What You See Is What You Get? Measuring Companies' Projected Employer Image Attributes Via Companies' Employment Webpages, Christian P. Theurer, Philipp Schapers, Andranik Tumasjan, Isabell M. Welpe, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Information on a company's employment webpage sends signals about the employer image the company intends to project to applicants. Nonetheless, we know little about the content of recruitment signals sent via company employment webpages. This study develops a method to measure companies' projected employer image attributes based on their employment webpages. Specifically, we analyze companies' projected employer image attributes by applying computer-aided text analysis (CATA) to the employment webpages of 461 Fortune 500 companies (i.e., more than 11,100 individual pages). Our results show that projected employer image attributes remain relatively stable over time. Moreover, we find relatively low levels of …


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 Sep 2022

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 Sep 2022

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 Sep 2022

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 …


Attraction Versus Competition: A Tale Of Two Similarity Effects In Director Selection Of Chinese Firms, Gao Renfei, Helen Hu, Toru Yoshikawa Sep 2022

Attraction Versus Competition: A Tale Of Two Similarity Effects In Director Selection Of Chinese Firms, Gao Renfei, Helen Hu, Toru Yoshikawa

Research Collection Lee Kong Chian School Of Business

Extant research has focused primarily on the collaborative side of chair-director similarity in director selection, whereas the potential competitive side remains underexplored. Emphasizing the dual role of directors as both collaborators and competitors, as perceived by chairs, we incorporate both the similarity-attraction logic and the similarity-competition logic in director selection and develop a collaborative-competitive framework to reconcile the tension between them. Based on new director selection data from Chinese listed firms, we find that chair-director similarity in the competitive-oriented political background is negatively related to the likelihood of the director being selected—consistent with the similarity-competition logic, whereas chair-director similarity in …

Experiential Learning: The Case Of Training Mba Students In An Asian School, Chiyachantana N. Chiraphol, Kuan Yong David Ding, Jack Jiajun Hong

Research Collection Lee Kong Chian School Of Business

Consulting for a startup company is an effective way for Master of Business Administration (MBA) students to learn about management consulting, and the ways and means of a startup company. This paper discusses the experience of an MBA startup project within the context of a core corporate finance course. The project requires the active engagement of several groups of stakeholders—MBA students, the university’s entrepreneurship incubator, a selection of startup companies, and the project’s academic collaborators. In line with the literature, we find that entrepreneurship education through student-startup collaboration contributes to the students’ entrepreneurial learning, and that the offering of an …


Smart Charging Of Electric Vehicle: An Innovative Business Model For Utility Firms, Owen Wu, Safak Yucel, Yangfang (Helen) Zhou Sep 2022

Smart Charging Of Electric Vehicle: An Innovative Business Model For Utility Firms, Owen Wu, Safak Yucel, Yangfang (Helen) Zhou

Research Collection Lee Kong Chian School Of Business

Problem Definition: By providing an environmentally friendly alternative to traditional vehicles, electric vehicles will transform urban mobility, particularly in smart cities. In practice, once an electric vehicle is plugged in, the charging station completes charging as soon as possible. Given that the procurement cost of electricity and associated emissions vary significantly during a day, substantial savings can be achieved by smart charging—delaying charging until the cost is lower. In this paper, we study smart charging as an innovative business model for utility firms. Practical Relevance: Utility firms are already investing in charging stations and they can achieve significant cost savings …


Fractile Graphical Analysis In Finance: A New Perspective With Applications, Anil K. Bera, Aurobindo Ghosh Sep 2022

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 …


The Breadth Of Normative Standards: Antecedents And Consequences For Individuals And Organizations, Shilpa Madan, Shankha Basu, Sharon Ng, Krishna Savani Sep 2022

The Breadth Of Normative Standards: Antecedents And Consequences For Individuals And Organizations, Shilpa Madan, Shankha Basu, Sharon Ng, Krishna Savani

Research Collection Lee Kong Chian School Of Business

Normative standards refer to ideals to which people, products, and organizations are held. The present research (N = 2,224) investigates a novel construct—the breadth of normative standards, or the number of criteria that normative standards need to meet. Using archival and primary data in both organizational and consumer contexts, Studies 1–2 found that Indians’ and Singaporeans’ normative standards in several domains (e.g., a good job, a good body wash) needed to satisfy more criteria than those of Americans and the British. Using incentive-compatible designs, Studies 3–5 identified two downstream consequences of broader normative standards; decision-makers with broader standards pay greater …


Reaching For Rigor And Relevance: Better Marketing Research For A Better World, Shilpa Madan, Et. Al. Sep 2022

Reaching For Rigor And Relevance: Better Marketing Research For A Better World, Shilpa Madan, Et. Al.

Research Collection Lee Kong Chian School Of Business

Over the past several decades, scholars have highlighted the obligations and opportunities for marketing as a discipline to play a role in creating a better world — or risk becoming irrelevant for the largest problems facing consumers and society. This paper provides a framework to enhance the relevance and rigor of research in marketing that not only contributes new knowledge to science, but also makes a positive difference in the world. 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 …


Lived Religion In A Digital Age: Technology, Affect And The Pervasive Space-Times Of “New” Religious Praxis, Quan Gao, Orlando Woods, Lily Kong, Siew Ying Shee Sep 2022

Lived Religion In A Digital Age: Technology, Affect And The Pervasive Space-Times Of “New” Religious Praxis, Quan Gao, Orlando Woods, Lily Kong, Siew Ying Shee

Research Collection College of Integrative Studies

This paper explores how Christian practices of prayer are being reconfigured through digital media in Singapore. Although digital technologies are an area of burgeoning interest amongst social and cultural geographers, the ways in which these technologies reconfigure the space-times of religious praxis and engender new affective relations or subjectivities of religion have not yet been embraced. This paper fills the lacuna by bringing existing studies on religion, technology and affect into constructive conversation with each other. By elaborating on digital prayer as an affective assemblage of religious practice, we show how digital technologies blur institutional boundaries and create new affordances …


Individual Perceptions Of Climate Anomalies And Collective Action: Evidence From An Artefactual Field Experiment In Malaysian Borneo, Terry Van Gevelt, T. Zamanb, K.N. Chanc, M.M. Bennettd Sep 2022

Individual Perceptions Of Climate Anomalies And Collective Action: Evidence From An Artefactual Field Experiment In Malaysian Borneo, Terry Van Gevelt, T. Zamanb, K.N. Chanc, M.M. Bennettd

Research Collection College of Integrative Studies

We explore the effect of individual perceptions of climate anomalies on collective action within a context of environmental complexity and uncertainty. To do so, we construct two competing propositions that are theoretically robust but with very different real-world implications. Our first proposition suggests that collective action to adapt to climate change is likely to be more effective when perceptions of climate anomalies converge within a community. Our second proposition suggests the opposite: that convergence is likely to hinder adaptation behaviour. We use a community co-designed measure of perceptions and an artefactual field experiment to test our propositions and explore the …


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 Sep 2022

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 …

Chromosomal microarray (CMA) is a testing modality frequently used in pediatric patients; however, published data on its utilization are limited to the genetic setting. We performed a database search for all CMA testing performed from 2010 to 2020, and delineated the diagnostic yield based on patient characteristics, including sex, age, clinical specialty of providers, indication of testing, and pathogenic finding. The indications for testing were further categorized into Human Phenotype Ontology categories for analysis. This study included a cohort of 14,541 patients from 29 different medical specialties, of whom 30% were from the genetics clinic. The clinical indications for testing …

Analyzing The Impact Of Covid-19 Control Policies On Campus Occupancy And Mobility Via Wifi Sensing, Camellia Zakaria, Amee Trivedi, Emmanuel Cecchet, Michael Chee, Prashant Shenoy, Rajesh Krishna Balan

Research Collection School Of Computing and Information Systems

Mobile sensing has played a key role in providing digital solutions to aid with COVID-19 containment policies, primarily to automate contact tracing and social distancing measures. As more and more countries reopen from lockdowns, there remains a pressing need to minimize crowd movements and interactions, particularly in enclosed spaces. Many COVID-19 technology solutions leverage positioning systems, generally using Bluetooth and GPS, and can theoretically be adapted to monitor safety compliance within dedicated environments. However, they may not be the ideal modalities for indoor positioning. This article conjectures that analyzing user occupancy and mobility via deployed WiFi infrastructure can help institutions …
