Development and Exploration of End-User Healthcare Technology Acceptance Models

This dissertation consists of three studies that collectively investigate the factors influencing the consumer adoption intention towards emerging healthcare technologies. Essay 1 systematically reviews the extent literature on healthcare technology adoption and serves as the theoretical foundation of the dissertation. It investigates different models that have been previously applied to study healthcare technology acceptance. Meta-analysis method is used to quantitatively synthesize the findings from prior empirical studies. Essay 2 posits, develops, and tests a comprehensive biotechnology acceptance model from the end-user's perspective. Two new constructs, namely, perceived risk and trust in technology, are integrated into the unified theory of acceptance and use of technology. Research hypotheses are tested using survey data and partial least square – structural equation modeling (PLS-SEM). Essay 3 extends the findings from the Essay 2 and further investigates the consumer's trust initiation and its effect on behavioral adoption intention. To achieve this purpose, Essay 3 posits and develops a trust model. Survey data allows testing the model using PLS-SEM. The models developed in this dissertation reflect significant modifications specific to the healthcare context. The findings provide value for academia, practitioners, and policymakers.

The Effects of Generational Stereotypes and Attribute Affirmation on the Collection of Audit Evidence (open access)

The Effects of Generational Stereotypes and Attribute Affirmation on the Collection of Audit Evidence

As the workplace has evolved over the past few years, several studies have documented perceived differences in personalities, values, and preferences between generations in the workplace, including in public accounting. In this study, I examine whether exposure to a negative preconceived belief about a staff auditor's generation (generational stereotype) influences the affective state of staff auditors and ultimately causes them to reduce the extent to which they communicate with a client manager to gather the necessary information to perform an audit adequately. I also investigate whether attribute affirmation from a work buddy helps elicit positive affect to mitigate the effects that exposure to negative generational stereotypes may have on audit evidence collection. I conducted a 2 x 2 experiment using graduate auditing students as a proxy for staff auditors. I find that general affect (i.e., mood) rather than interpersonal affect (i.e., likability), drives the negative effect of exposure to generational stereotypes on willingness to collect more audit evidence. I also find that high levels of negative mood can negatively impact participants' self-efficacy. I, however, failed to find evidence of a moderated mediation. The presence of an attribute affirmation results in an insignificant increase in positive affect. When staff auditors are …

Corporate Environmental Litigations: Peer Effects and Its Relationship to Firm Environmental, Social and Governance (ESG) Performance

The dissertation analyzes three issues related to corporate environmental performance. In the first essay, I analyze the stock price reactions of the defendant firms and their peer firms to environmental lawsuits. Empirical evidence finds that the defendant and their peer firms experience negative and significant cumulative abnormal returns to the announcement of environmental lawsuits. Additionally, cross-sectional analyses find certain firm characteristics, such as profitability, growth opportunities and leverage can influence the market reaction. Furthermore, if the plaintiffs are government agencies or corporations instead of individual citizens, the defendant and peer firms experience higher negative market reactions. The second essay examines if a firm's environmental, social, and governance (ESG) performance can moderate the negative market response to environmental lawsuits. The results are mixed. The overall sample of the defendant and their peer firms show that ESG performance is not a significant factor in mitigating the negative market response. However, an interesting finding shows, for defendant and peer firms in the environmentally sensitive industries, better ESG ratings help reduce the adverse market reactions. The final essay investigates whether the defendant and peer firms improve their ESG performance in the next two years following the lawsuits. The results indicates that firms generally experience …

Worker Displacement by Artificial Intelligence (AI): The Impact of Boundary-Spanning Employees

Limited literature examines the impact of the displacement of boundary-spanning employees artificial intelligence (AI). Scholars and practitioners appear focused on tangible benefits of AI adoption, and do not seem concerned by any less tangible and possibly untoward implications of worker (particularly boundary-spanning worker) displacement. My dissertation addresses this gap in the literature. In Essay 1, a qualitative study is performed to anchor the research on the appropriate ethnographic setting, the firms where this displacement phenomenon is taking place, by utilizing the Straussian grounded theory approach. The outcome of iterative coding of the first order data collected from the interviews and content analysis is a conceptual framework which amongst other findings shows how the unique competences of boundary-spanning employees and those of AI are best suited for different spectra of interorganizational collaborative activities. In Essays 2 and 3, I investigate major themes that emerged from Essay 1 utilizing quantitative and qualitative research methods in both studies. Initially I test research models using structural equation modelling on practitioner survey data, after which I probe further via focused interviews to better understand the survey results. The two papers allow us to put forth several theoretical and managerial contributions, specifically emphasizing the positive essential …

Who are You Going to Believe: Me or Your Lying Eyes? Three Essays on Gaslighting in Organizations

In this dissertation, I theorize on how gaslighting manifests in managerial and organizational settings. I discuss the process of gaslighting and how the use of various manipulation tactics manifests between people in organizations over time. I take three distinctive approaches to study this complex phenomenon. First, using a rich case study, I develop new theory to explain how one notorious child molester was able to sustain a career for decades while assaulting hundreds of children and young women. In doing so, I introduce the concept of gaslighting which previously has only been rigorously applied to intimate interpersonal relationships in domestic (e.g., at home) settings. In essay 2, I expand on the individual level theory developed in essay 1 to develop a more generalized theory of gaslighting in organizations. I situate gaslighting within a nomological net of related constructs and illustrate how gaslighting is a unique construct with different antecedents and consequences that occurs in organizations more often than it should. In my final essay, I build on one of the propositions developed in essay 2 and empirically test what antecedents are likely to influence whether or not a firm is accused of gaslighting on Twitter. Through doing so, I find …

Freight Forwarder Satisfaction: A Conceptualization and an Empirical Test of Effect on Airport Customer Loyalty and Competitiveness

In 2018, global gross domestic product (GDP) was US$86.3 trillion, and almost a quarter of that value was due to international trade with a value of US$19.6 trillion. Air cargo accounts for about 35 percent of that trade value (approximately US$6.86 trillion). Moreover, from the perspective of the airport sector, air cargo revenue contributes between 20 to 70 percent of airport revenue. The global airport revenue for freight in 2018 was US$250 billion. Despite the interest and research activities surrounding competition and competitiveness of airports and specifically among airlines and passengers, it appears scholars have overlooked research concerning the competitiveness of airports when it comes to air cargo. This study attempts to fill the gap in the supply chain and logistics literature by putting forward a framework and ultimately operationalizing the framework highlighting the pivotal role of air cargo in the supply chain domain and within the global economy. Specifically, the framework is operationalized within the freight forwarding air cargo supply chain domain – providing insight into this important yet understudied phenomenon. The population of interest is freight forwarders from the Dubai International Airport, United Arab Emirates. The Middle East represents 18 percent of the world's air cargo volume and …

The Determinants and Consequences of Having a Chief Operating Officer (open access)

The Determinants and Consequences of Having a Chief Operating Officer

This study examines the determinant and consequences of having a chief operating officer (COO). Specifically, we investigate chief executive officer (CEO) related factors that affect the choice to employ a COO and look into the impact of having a COO on firm operational efficiency using a data envelopment analysis (DEA)-based measure. Although prior literature has extensively investigated the role of CEOs and chief finance officers (CFOs) on firm outcomes, few studies focus on the impact of COOs. Thus, this study explores characteristics associated with the likelihood that a firm will have a COO. This research also sheds light on the effect of COOs on firm operational efficiency because the core duties of COOs include optimizing operational performance and improving cost efficiency. Our results imply that CEO busyness, CEO ability, CEO demographic characteristics, and CEO network size have a significant impact on the decision to employ a COO. We also find that firms that have a COO have a lower level of operational efficiency than firms that do not. This result implies that the cost of having a COO outweighs the benefit of having one. The effects last for three years on average. Further, we find that firms with a COO …

Three Essays on the Role of Social, Legal and Technical Factors on Internet of Things and Smart Contracts Adoption in the Context of COVID-19 Pandemic

I extended and adapted the current technology acceptance models and privacy research to the peculiar context of the COVID-19 pandemic to ascertain the effective "power" of IT in fighting such a pandemic. The research models developed for the purpose of this study contain peculiar modifications to the technological-personal-environmental (TPE) framework and privacy calculus model because of the unique technologies implemented and the peculiar pandemic scenario. I developed three studies that investigate the interaction between social, legal, and technical factors that affect the adoption of IoT devices and blockchain systems implemented to fight the spread of COVID-19. Essay 1 systematically reviews existing literature on the analysis of the social, legal, and technical components in addressing phenomena related to IoT architecture and blockchain technology. The employment of a comparable coding method allows finding which of the above components is prominent in relation to the study of IoT and blockchain. Essay 2 develops a technological acceptance model by integrating the TPE framework with new constructs, i.e., regulatory environment, epidemic ecosystem, pre-epidemic ecosystem, perceived social usefulness, and technical characteristics. Essay 3 further explores the interplay between social, legal, and technical factors toward the adoption of smart contracts in the context of the COVID-19 pandemic. …

Client Narcissism and the Decision to Switch Tax Professionals (open access)

Client Narcissism and the Decision to Switch Tax Professionals

Contentious interactions may arise between a tax professional and client upon a disagreement over a tax position. In an increasingly competitive tax return preparation market, these contentious interactions represent a significant threat to tax practitioners' client satisfaction and retention objectives. I conduct an experiment in which I examine the effect of three factors on tax clients' (1) likelihood to accept the advice of the tax accountant and (2) likelihood to switch tax accountants upon receiving professional advice counter to their preferred tax position. The three factors are: (1) clients' antagonistic narcissism; (2) clients' relationship with the accountant; and (3) how the advice is framed by the tax accountant. The results are based on a sample of 93 taxpayers. First, this study examines how clients' measured levels of narcissistic antagonism (hereafter, antagonism) impacts their reaction to "being told no" by their tax professional. Results indicate that upon the receipt of advice contrary to their preferences, highly antagonistic clients are more likely to (1) engage in a contentious interaction with their professional and (2) switch to a new tax professional. Supplemental path analyses document that individuals with high levels of antagonism cognitively react to instances of "being told no" by simultaneously devaluing …

Corporate Social Responsibility and Brand Equity: Insights to Global, Luxury, and Co-Creation Brand Building Strategies (open access)

Corporate Social Responsibility and Brand Equity: Insights to Global, Luxury, and Co-Creation Brand Building Strategies

Given the growing number of socially conscious and ethical consumers, brands have been taking a strategic approach to corporate social responsibility (CSR) by integrating socially responsible activities into the brand's core value proposition in order to remain relevant in the marketplace and drive brand equity. Extant research on CSR has investigated its effect on various consumer behavior outcomes. However, from a brand-building perspective, there is still a lack of understanding on how to effectively leverage CSR, and not enough directions on how to overcome its challenges in order to build brand equity. Therefore, through three essays, the objective of this dissertation is to provide a deep understanding of the effect that CSR has on brand equity while revealing brand-building strategies that can be implemented to effectively leverage CSR, specifically within the (1) global, (2) luxury, and (3) co-creation contexts.

Determinants of Portfolio Manager Ownership

This paper investigates the determinants of mutual fund portfolio manager ownership and its association with fund performance. Using hand-collected data of 1,420 U.S. equity funds from 32 fund families, we find that variations in fund manager holdings are broadly consistent with optimal contracting theory instead of the result of managers' personal investment consideration. Portfolio manager ownership is positively and significantly correlated with variables that proxy for intensity of agency conflicts. Specifically, portfolio managers hold more mutual fund shares when the size of concurrently managed hedge fund increases and when the advisor is affiliated to the bank. In addition, fund managers invest more in funds with primary investment in growth stock, non-index funds, and solo-managed funds. Regarding to the alternative governance mechanism, higher threat of dismissal for outsourced funds, stronger monitoring from institutional investors, and long-term performance based bonus work as substitutes of fund manager ownership while director ownership works as a compliment. Finally, we find little evidence supporting the notion that funds with higher portfolio manager ownership perform better.

Attaining Team Psychological Safety to Unlock the Potential of Diverse Teams

Team psychological safety fosters interpersonal risk-taking and constructive debate. Yet, how psychological safety develops in diverse teams needs to be explained. I apply collective regulatory lenses to shed light on how collective prevention focus (status quo) and collective promotion focus (growth) uniquely affect team psychological safety. I believe promotion focus makes it easier to attain psychological safety, while prevention focus makes it harder. Under a collective promotion lens, teams seek growth. Under a collective prevention lens, teams desire protection and not making things any worse. A pilot study of 76 students in 17 student project teams provided initial support for individual relationships in my model. In Study 2, an experiment, I manipulated team regulatory foci in three tasks (building towers, selling a house, negotiating a salary). I did not find significant mean group differences in psychological safety between promotion (n = 17) and prevention (n = 15) teams; yet, promotion teams experienced greater team viability in the final activity. In Study 3, I employed an experimental vignette method that suggested leadership conditions (e.g., leader humility vs transactional leadership) created differences in regulatory foci and subsequent differences in psychological safety with 343 working professionals in 7 scenarios.

What Type of Follower Will I Be? Leader Behavior and the Motivational Processes Underlying Follower Role Orientation

In a society fixated on leaders, where does that leave followers? Followership highlights the follower in the leadership process, examines who are followers, and explores how and why people follow. Much of the existing literature on followership has focused on classifying followers into follower types. However, less is known about why an employee might enact a particular follower role. The purpose of this dissertation is to understand how leaders influence the likelihood that followers to enact a particular follower role orientation, either coproducing or passive. Specifically, this research contributes to understanding the impact of transformational leadership on follower motivation and follower role orientation. An additional contribution of this dissertation is to establish the theoretical mechanism that explains the connection between leader behavior and follower role orientation by integrating self-determination theory (SDT) into the process of followership. Through SDT, we gain understanding of the origins of these roles by explaining their underlying motivation. Study 1 consisted of sequential experiments with a between-subject design that used distinct vignettes for transformational leadership and work-based need satisfaction. Findings support the causal relationship between transformational leadership and follower needs satisfaction; however, the casual relationship between follower need satisfaction and follower role orientation was not significant. …

Two Essays Examining the Effects of AIVA Search on Cognition, Emotion and Choice

AI-enabled virtual assistants (AIVAs) have become increasingly popular (e.g., Amazon Alexa, Google Home) and assist consumers with various tasks, including home automation, access to media, entertainment, and shopping. Essay 1 focuses on the outcomes of consumers' lost autonomy after information search using AIVAs versus an online search engine (e.g., Google). Drawing on research in advances in AI technology, I predict that interacting with AIVAs (versus online search engines) will lead to several consumer outcomes: decreased cognitive task performance, word of mouth (WOM) intentions, and the desire for an unrelated subsequent search. I find support for my predictions across five studies, using different tasks to assess performance (verbal and quantitative), after interactions with both real (Amazon Alexa) and fake (Halo) AIVA brands, across different respondent populations (CloudResearch, MTurk, Prolific), thereby enhancing confidence in my findings. In Essay 2, I consider a different consumer outcome - embarrassment, and also a different underlying process variable – social presence. I predict that when consumers engage in information search using an AIVA, they will subsequently experience greater embarrassment when asked about embarrassing products (e.g., condoms, medication for gas, etc.). The increased embarrassment occurs even when the information search is unrelated to the embarrassing products (e.g., …

Three Essays on Social Media Use and Information Sharing Behavior

Social media platforms create rich social structures, expand users' boundaries of social networks and revolutionize traditional forms of communications, social interactions and social relationships. These platforms not only facilitate the creation and sharing of news and information, but they also drive various kinds of businesses models, processes and operations, knowledge sharing, marketing strategies for brand management and socio-political discourses essential for healthy and democratic functions. As such, social media has greater implications on organizations and society brought about by individuals' social media usage patterns, and therefore, calls for further investigations. The main objective of this dissertation is to explore and offer insights into such social media usage and information sharing behaviors via data driven examination of various theories. This dissertation involves three studies that focus on factors that explain individuals' three different social media usage behaviors. Essay 1 investigates individuals' perceived importance of online affiliation, self-esteem, self-regulation and risk-benefit structure as antecedents of users' geo-tagging behavior on social media. Essay 2 examines the role of online news quality, source credibility, individuals' perception towards online civic engagement, attitude towards news sharing and social influences to understand users' news sharing behavior on social media platforms. Essay 3 seeks to examine the individuals' …
