"This research study shall be the advancement of the Negro within business and professional enterprises in Texas since 1900. The objective is to discover if and where the colored people have made progress. If progress has been made, it must be due to some prevailing influence, and if no progress has been made, there has evidently been some hindering cause. This research shall try to discover these factors and record the results as they affected the progress of these people. It is the intention of this writer to race the educational, economic, and social advancement of these people and to show in what fields of endeavor they have advanced and in which fields they have failed. This advancement shall be traced from the year 1900 to the year 1950, showing the progress in ten year intervals."-- leaf 1.

The objective of this dissertation is to first identify if there are any academic research gaps in our understanding of the medical supply chain and secondly to understand the role and impact of logistics on the human organ transplant process. The first essay identifies the current status of medical supply chain literature and provides future direction for improving the medical supply chain. This was accomplished by preforming a systematic literature review and a bibliometric analysis from 2,160 publications was conducted. The second essay explores how logistical aspects impact transplant logistics performance and the quality of life for the transplant recipient. Survey data was collected from medical professionals and analyzed using structural equation modeling. The third essay identifies the factors are influencing the number of donor kidneys discarded each year. A retrospective analysis of all deceased donor kidneys procured in hospitals in UNOS region 4 (Texas and Oklahoma) from January 1, 2001, to June 28, 2021, was conducted. Data was analyzed using multinomial logit regression and panel data analysis. As a result, we identified several medical and logistics factors that have influenced the number of donor kidneys discarded in the United States.

Linguistic racism is faced by non-native customers due to their different language style when they go through the service exchange process. Despite its prevalence and importance, there is a dearth of research about linguistic racism in the marketing literature, especially from consumers' perspectives. This dissertation thus aims to address this gap by focusing on consumers' cognitive and affective responses as a result to their linguistic racism experiences when they interact with service employees (native speakers) from the host country. Toward this goal, first (Essay 1), a qualitative study is performed to anchor the dissertation in the customers' real-life experiences and to help identify key associated themes which are further empirically examined (Essay 2 & 3) in this three-essay format dissertation. Essay 2 empirically investigates if the identity assignment through ones' language style makes customers feel stigmatized and influence their psychological well-being. In addition, how these experiences subsequently influence their inclination to use technology-mediated interfaces. Similarly, the main objective of Essay 3 was to employ a sociological perspective to examine the impact of language-based chronic social exclusion on non-native customers' psychological and behavioral responses in the marketplace. Moreover, their intention to pay higher tip as a refocusing strategy when these customers …

Managers rely on analytics to make decisions and the choice of the analytical method can influence their decision-making. This dissertation considers three cases and examines how the choice of analytical methods influence interpretations and implications. These areas are communication for health-related information in social media, health information technology investment by hospitals as it relates to patient satisfaction, and health related expenditure policies of countries. These studies develop theoretical models and empirically test them on primary or secondary data, comparing the performance of popular analytical methods. The conduct of these three studies contributes to a better understanding about the choice of analytical methods and allow development of a heuristic approach by offering guidelines for selecting an appropriate methodology. They demonstrate the value of heuristic approaches for use with non-traditional and traditional statistical methods, as the information gained from non-traditional methods (NNs) provides insights into traditional statistical methods, similar to insights gained from exploratory data analysis. The studies also show the value in examining any dataset with multiple methods because they either confirm each other or fail to confirm, providing insights.

Supply chain transparency is principally focused on a company's efforts toward disclosing information about their products, and their supply chain operations to the public. Essay 1 is a conceptual paper that examines the risks of disclosing supply chain mapping information to consumers and proposes an approach to developing risk mitigation strategies. This essay also develops a set of supply chain mapping conventions that support the development of an agility-focused supply chain map. Essay 2 employs an experimental design methodology to examine the impact of disclosing the ethnicity of a supplier on consumers' behaviors, while also capturing the extent to which a consumers' ethnic identity and prosocial disposition influence their behaviors. Finally, also using an experimental design, Essay 3 analyzes consumer outcomes based on disclosing no, partial, and full supply chain transparency information, and accounts for heterogenous consumer traits such as the importance of information to a consumer and their perceived quality of information. Collectively, these essays advance the body of knowledge that seeks to understand the risks and benefits of supply chain transparency, by conceptually identifying risks and proposing an approach to minimize the risks associated with supply chain transparency, and by illuminating the conditions that prompt favorable consumer outcomes.

The problem with which this investigation is concerned is whether or not dogmatism and neuroticism in supervisors of sheltered workshops is related to changes in the self-concept of handicapped employees. The measurements of dogmatism and neuroticism were accomplished through the use of Rokeach's Dogmatism Scale, (form E) and Winne's Neuroticism Scale. Pitt's Tennessee Self Concept Scale was used to measure the self-concept of the handicapped employees.

This work embraces three essays on information privacy: 1) Measures of Personal Information Privacy in Social Networks: Information Control and Situation Awareness, 2) Care to Share your Personal Information? and 3) Privacy Breaches: How Resilient Are You? Every transaction made either online or offline, and every social interaction that is transferred or stored electronically in some way, are generally consumed as big data and ultimately drives the analytics from which consumers benefit. However, this raises some concerns about privacy and ethics. For example, should companies that consumers interact with be allowed to sell their personal information? Consumers derive certain benefits such as personalized content when they choose to offer their data to many websites. However, consumers providing personal data to websites subject themselves to possible privacy invasion when third parties purchase their data. In this case, since the consumer willfully gave away their personal information, is it genuinely personal, and should they retain some, if any, control over it? Theories such as privacy calculus and protection motivation theory (PMT) are a couple of prominent examples that focus on the privacy risks and benefits that drive consumer behavior. However, there is still a lack of research on the instantiation of privacy …

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' …

The hospitals and their healthcare providers need to optimize simultaneously three outcomes: healthcare costs, healthcare options offered to customers, and information utilization efficiency. The adoption of electronic healthcare record (EHR) technologies is a potential managerial mechanism for balancing these outcomes. EHR offers patient management and decision support capabilities that can ameliorate health delivery outcomes for patients, doctors, and hospitals through better-informed business and care decisions. The analysis of data collected in an EHR system may lower costs and improve health care delivery (or both). In sum, it could be argued that EHR is a source of competitive advantage. Despite this prima facie appeal, many hospitals remain reluctant to adopt and implement EHR due to lack of insights into return on investment, unavailability of tested systems and data entry obstacles. To address this gap between the potential of EHR system and lack of its adoption, the purpose of this research is to investigate the role of EHR as a resource of competitive advantage for hospital. Essay 1, titled "Implementation and Adoption of EHR: A Conceptual Model based on Resource Advantage Theory", describes the antecedents and consequences of EHR adoption and implementation. Essay 2, titled "Exploring the Relationship Between Electronic Healthcare Record …

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.

This research aims to investigate the (1) review effects on consumer decision making process, (2) effects of negative reviews on brand equity, and (3) consumers' likely response to a brand's request for reviews. The objective of the first essay is to investigate the nature of the relationship between skepticism and consumer decision making in an online behavior context. Its second objective is to know whether people's belief on their abilities or their hedonic principle moderates the relationship between a person's skepticism toward online reviews and their reliance on online reviews. The objective of the second essay is to explore whether negative online reviews that focus on service quality specific dimensions have a different effect on a service organization's perceived brand equity. Its second objective is to analyze the role of emotional contagion in the relationship between negative reviews related to various service quality dimensions and its effect on perceived brand equity. The main objective of the third essay is to know whether consumers are more likely to write an online review for a brand when the request comes from a higher equity brand. This essay also investigates how message trust and persuasion knowledge influence the relationship between a brand's request …

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 …

There is currently an increasing trend among the American working population to voluntarily join the gig economy. New terms like the gig economy, sharing economy, internet freelancing, and eLancing have been created to understand this emerging trend among today's workforce. There is a small, yet highly relevant, body of scholarly literature in human resource management that is focused specifically on the eLancing economy as a subset of the gig economy. The purpose of this research is to acknowledge and contribute to this timely literature, which has adequately recognized the enormous potential of this new trend of working. Grounded in the psychology of working theory, a theoretical typology of eLancers is proposed based on the workers' level of volition to be able to choose eLancing as their employment. Further, various predictors such as demographics and personality characteristics were explored on the basis of which eLancers can be classified into types. The study also proposes that different types of eLancers differ in their attitudinal and behavioral work and life outcomes. Prior research has shown that career decisions made by individuals with high work volition relate to higher levels of overall well-being. Hence, classifying eLancers on the basis of their varying levels of …

This manuscript includes an investigation of decision making in alternative modes of transportation in order to understand consumers' decision in different contexts. In essay 1 of this study, the motives for participation in situated ridesharing is investigated. The study proposes a theoretical model that includes economic benefits, time benefits, transportation anxiety, trust, and reciprocity either as direct antecedents of ridesharing participation intention, or mediated through attitude towards ridesharing. Essay 2 of this study, focuses on self-driving vehicles as one of the recent innovations in transportation industry. Using a survey approach, the study develops a conceptual model of consumers' anticipated motives. Both essays use partial least square- structural equation modeling for assessing the proposed theoretical models.

My aim is to design a research program that emphasizes inclusivity through empiricism rather than anecdotes and benevolent sexism. To accomplish this goal, I review and build on the work assessing the influence of fertility in the female consumer experience (FCE). Fertility, especially menstruation, has been used anecdotally for too long. This research was designed to address the gap in knowledge around the way in which women perceive advertisements. More specifically, the role fertility plays in the process women go through when assessing advertisements and offerings. Does a woman's desire to seek variety become reduced when she sees a rival endorsing the offering? If this is the case, then there is a need to find a mediating variable that can overcome this effect. Internal locus of control, the level a person feels they are in control of the outcomes in their lives, was selected as a starting point. Having a high internal LOC should buffer a person's perceptions of another as a threat. A cross-sectional design from a convenience sample of university students was used to address a series of five research questions: 1) Does fertility status influence locus of control, 2) Does fertility status influence rival assessment, 3) Does …

Today's environment is filled with the proliferation of cyber-attacks that result in losses for organizations and individuals. Hackers often use compromised websites to distribute malware, making it difficult for individuals to detect. The impact of clicking through a link on the Internet that is malware infected can result in consequences such as private information theft and identity theft. Hackers are also known to perpetrate cyber-attacks that result in organizational security breaches that adversely affect organizations' finances, reputation, and market value. Risk management approaches for minimizing and recovering from cyber-attack losses and preventing further cyber-attacks are gaining more importance. Many studies exist that have increased our understanding of how individuals and organizations are motivated to reduce or avoid the risks of security breaches and cyber-attacks using safeguard mechanisms. The safeguards are sometimes technical in nature, such as intrusion detection software and anti-virus software. Other times, the safeguards are procedural in nature such as security policy adherence and security awareness and training. Many of these safeguards fall under the risk mitigation and risk avoidance aspects of risk management, and do not address other aspects of risk management, such as risk transfer. Researchers have argued that technological approaches to security risks are rarely …

This dissertation is designed to answer the following questions: (1) Which measurement model is better to contribute to the research model in different areas? (2) Within a given model, how does the data size influence the performance of a neural network (NN) and some other methods? (3) Compared to partial least square (PLS), ordinary least square (OLS), XGBoost, how is the performance of NN? Essay 1 systematically compares PLS-SEM to ANN and builds the hybrid vehicle purchasing intention model (HVPIM). It investigates different models that have been previously applied to study the theory of planned behavior (TPB). The methods find those factors that significantly correlated with consumer purchase intention. Essay 2 posits, develops, and tests a PNN model with healthcare data. A research survey is designed and distributed to undergraduate students from a major research school in the U.S. southwest region. Research hypotheses are tested using PLS-SEM and PNN. Essay 3 targets on testing the performance of the NN model with panel data from the soccer transfer market. To achieve this purpose, the essay posits and develops an empirical test built on game theory. The NN model is tested and compared to OLS and XGBoost. As the research compares the …

This study addresses the antecedents of individuals' disposition to use telemedicine applications, as well as the antecedents of their usage to provide insight into creating sustained usage over time. The theoretical framework of this research is Bhattacherjee's expectation-confirmation IS continuance model. By combining a series of key factors which may influence the initial and continued usage of telemedicine applications with key constructs of Bhattacherjee's IS continuance model, this study aims to provide a deeper understanding of barriers to telemedicine app usage and how to facilitate continued use of these apps. Online survey data was collected from college students who are telemedicine application users. A total of 313 responses were gathered, and data analysis was conducted using SmartPLS 3. This dissertation contributes by looking at the IS adoption and IS continuance research simultaneously to connect these two research streams as well as suggesting the usage context of some established IS theory being different with regard to healthcare applications.

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., …

Ambient lighting has emerged as a key atmospheric factor influencing how consumers process environmental cues and their behaviors. However, surprisingly little research has examined how people think and feel in the dark (lower than 15 lux). This is particularly relevant given that consumers routinely work, pay bills, relax, consume and make purchases in settings with little or no light. My dissertation addresses this gap by examining how consumers regulate their goals and process information when the light is off, and how that impacts their decision making in three substantive domains: risk-taking behavior, decision quality, and persuasion. In Essay 1, I propose darkness enables risk-taking behavior, and this effect happens through the calmness and relaxation induced in the dark. One caveat is that the decisions have to be made in a familiar setting. The effect was reflected in participants' decisions to invest in riskier yet lucrative stocks, to gamble with the riskier choice, to eat at a foreign restaurant, and to choose a supplement that has potential side effects in a field experiment and three lab experiments (pre-registered). In Essay 2, I propose that when the light is off, consumers are indeed induced to adopt an effortful processing mode. Across four …

In this work, we focus on enhancing the efficacy of predictive modeling in operational management decision making in two different settings: Essay 1 focuses on demand forecasting for the companies and the second study utilizes longitudinal data to analyze the illicit drug seizure and overdose deaths in the United States. In Essay 1, we utilize an operational system (newsvendor model) to evaluate the forecast method outcome and provide guidelines for forecast method (the exponential smoothing model) performance assessment and judgmental adjustments. To assess the forecast outcome, we consider not only the common forecast error minimization approach but also the profit maximization at the end of the forecast horizon. Including profit in our assessment enables us to determine if error minimization always results in maximum profit. We also look at the different levels of profit margin to analyze their impact on the forecasting method performance. Our study also investigates how different demand patterns influence maximizing the forecasting method performance. Our study shows that the exponential smoothing model family has a better performance in high-profit products, and the rate of decrease in performance versus demand uncertainty is higher in a stationary demand environment.In the second essay, we focus on illicit drug overdose …

This dissertation research explores the factors that influence direct selling agents' sales performance and job satisfaction. In the direct selling channels, the agents not only sell the products to customers. They may concurrently perform a "distributor" role as a stand-alone entity composed of their own sales network. This dissertation research features two essays. The first essay investigates how direct selling agents' perceptions of control and sense of belonging relate to PO. This essay further explores how PO influences job performance and job satisfaction. Results suggest that perception of control and sense of belonging fuel PO. Furthermore, leader-member exchange mediates the relationship between PO and sales performance, as well as PO and job satisfaction in direct selling networks. The second essay introduces a new construct (relational incongruity) and discusses how complex sales environments and direct selling agents' organizational structures influence the relational incongruity in their organization and its ensuring effect on sales performance and job satisfaction. The results indicate that organizational complexity is positively related to relational incongruity. However, customer complexity has a negative impact on relational incongruity. Relational incongruity in direct selling agents' organizations has negative effects on job satisfaction but has no effects on sales performance. Epistemic curiosity undermines …

The technology for storing and using big data is evolving rapidly and those that can keep pace are likely to garner additional competitive advantages. One approach to uncovering existing practice in a manner that provides insights for building theory is the use of grounded theory. The current research employs qualitative research following a grounded theory approach to explore gap in understanding the relationship between big data (BD) and the supply chain (SC). In this study eight constructs emerged: Organizational and environmental factors, big data and supply chain analytics, alignment, data governance, big data capabilities, cost of quality, risk analysis and supply chain performance. The contribution of this research resulted in a new theoretical framework that provides researchers and practitioners with an ability to visualize the relationship between collection and use of BD and the SC. This framework provides a model for future researchers to test the relationships posited and continue to extend understanding about how BD can benefit SC practice. While it is anticipated that the proposed theoretical framework will evolve as a result of future examination and enhanced understating of the relationships shown the framework presented represents a critical first step for moving the literature and practice forward.

The writer purposes in this study to make a survey of the airline industry in the United States from 1940 through 1946. Various phases of the development and present status of air commerce are to be dealt with, including historical growth of the airline industry, the present significance of air transportation in the nation, the federal regulation of airplanes, problems and services involved in commercial air transportation, the operation of airlines, and the future of air transportation.
