Joint Chance-Constrained Staffing Optimization In Multi-Skill Call Centers, Tien Thanh Dam, Thuy Anh Ta, Tien Mai

Research Collection School Of Computing and Information Systems

This paper concerns the staffing optimization problem in multi-skill call centers. The objective is to find a minimal cost staffing solution while meeting a target level for the quality of service (QoS) to customers. We consider a staffing problem in which joint chance constraints are imposed on the QoS of the day. Our joint chance-constrained formulation is more rational capturing the correlation between different call types, as compared to separate chance-constrained versions considered in previous studies. We show that, in general, the probability functions in the joint-chance constraints display S-shaped curves, and the optimal solutions should belong to the concave …

The Effect Of Technology And Regulation On The Co-Evolution Of Product And Industry Architecture, Nicholas Burton, Peter Galvin

Research outputs 2022 to 2026

This paper explores the co-evolution of product and industry architecture by drawing on a longitudinal study of the UK personal pensions industry between 2005 and 2020. It provides qualitative evidence for the way in which institutional structures, particularly regulation, entwine with firm strategic choices to shape the contours of an industry value chain (IVC). We draw upon modularity theory and the literature on industry architecture to consider how strategic bottlenecks emerged and how value shifted between layers of the IVC. Furthermore, we examine the interplay between the agendas of the regulator and firm strategic responses to unpack how firms (product …

Three Chapters On Investments And Financial Institutions, Cao Fang

Graduate Theses and Dissertations

Only the stock selection (“alpha”) decisions of fund managers who trade on firm-specific information should have predictive return content. Faced with the same information, skilled fund managers make similar stock selection decisions. In Chapter one, we introduce a new measure - stock investment quality - which uses fund quality to weight asymmetries in private information reflected in deviations of fund from peer group ownership on stocks in a style segment. We show stocks ranked high on investment quality generate significantly higher excess returns that persist through the ensuing year. The positive investment quality–future return relationship is robust to alternative fund …

Technology Agency On Usage: Grounded Theory And Measurement Of Technology Induced Usage Behavior, Sandip Kumar Sarkar

Graduate Theses and Dissertations

Most of today’s software applications involve a dyadic interplay between human and technology agency. The use of algorithms driven by user can alter users' interaction patterns by affording them novel and relevant technology action possibilities. I argue that algorithmic activities and features embedded in apps can keep users on IT applications (apps) for longer periods of time. I refer to the behavior of interacting with the apps for longer time than planned as technology-induced excessive use. While practitioners are beginning to recognize characteristics of technology-induced excessive use, research on this topic is very limited. I used a multimethod approach to …

The Buzz Behind Alcohol Advertising: A Study Of How Alcohol Advertisements On Social Media Impact Behavior, Alexis Morgan Campbell

Graduate Theses and Dissertations

Alcohol advertisements are known to be appealing and memorable, and several researchers have investigated what makes these advertisements so attractive. Several trends have emerged regarding the content within alcohol advertisements: themes of parties, celebration, and social success within television, magazines, and social media since the 1970s. Recently, several studies found that new themes in alcohol ads have been found to be popular, especially in social media advertisements (Campbell & Chung, 2022). The elaboration likelihood model (ELM) provides insight into why a person’s attitude could be more susceptible or why their behavior could be more easily influenced by certain types of …

Closing The Gender Gap In Entrepreneurship Education, Carolyn J. Rodeffer

Graduate Theses and Dissertations

Entrepreneurship education in higher education has been cited as a key strategy in filling the entrepreneurship talent pool, preparing students with the skills and confidence needed to start new ventures (Westhead & Solesvik, 2016). However, outcomes of entrepreneurship education for female students are less positive than for their male counterparts (Shinnar et al., 2012; Westhead & Solesvik, 2016; Wilson et al., 2007). Working within the frameworks of Bandura’s self-efficacy theory (1977), Azjen’s theory of planned behavior (1991), and Steele and Aronson’s stereotype threat theory (1995), this quantitative study utilized an experimental research design to assess the impact of role model …

Beyond Nutrition: Three Essays On The Effects Of Food Processing And Sustainability Labeling On Consumer Perceptions And Evaluations, Garrett J. Rybak

Graduate Theses and Dissertations

Recent consumer trends reveal increasing demand for greater product transparency including how products are processed, the types of ingredients used, and the impact on the environment. As a result, food marketers often use a combination of processing, nutrient content, and/or sustainability claims to convey specific information to consumers. Considering these developments, several questions arise about how these claims affect consumer evaluations of healthfulness, sustainability, disease risk, and intent to purchase while considering the unregulated and regulated nature of many of these claims.

In Essay One, we extend our understanding of consumer responses to package claims by comparing the direct and …

The Effects Of Consumer Loan Application Formats And Advertised Terms On Consumer Borrowing Decisions, Alicia M. Johnson

Graduate Theses and Dissertations

Consumers continue to demonstrate a willingness to accrue more debt. They are also more accepting of increased repayment risk via the acceptance of longer loan terms. Extant research on consumer borrowing consists primarily of experiments designed to assess consumer choices and understand how consumers evaluate loan attributes in relation to one another within consumer borrowing contexts (Kamleitner, Hoelzl, and Kirchler 2012; Ranyard et al., 2006). Thus, prior research examines consumer responses to loan information rather than the generation of loan parameters at the time of financing. With important implications for consumers, marketers of financial products, academic researchers, and federal regulators, …

Three Essays On The Effect Of Scarcity On Consumer Behavior And Firm Performance, Pritosh Kumar

Graduate Theses and Dissertations

Studies have consistently shown that scarcity plays a significant role in shaping decision making. Under conditions of scarcity, individuals tend to behave impulsively, and firms are inclined to redefine their set of priorities and strategies, ultimately impacting their performance. Considering the scant investigation of the mechanisms and effects of scarcity in the supply chain management literature, this dissertation aimed to investigate the roles of scarcity in shaping consumer behavior and firm strategy in three essays.

The first essay investigated the effect of post-stockout scarcity disclosures on consumer responses to stockouts through the lens of product scarcity and signaling theory. The …

Full Disclosure: Model Uncertainty In Adjusting For Confounders, Dieudonne Dusenge

Graduate Theses and Dissertations

This study examines the role of knowledge about underlying causal relationships in classifying controls in order to mitigate omitted- and included-variable biases. Using simulations and accounting examples, the study shows that the researcher may not distinguish good and bad controls because the underlying causal relationships are unobservable, and remedying strategies (such as the relative timing of measurement) may not remove the uncertainty in the classification. Because of the uncertainty about which controls to use, two or more models will be credible as will the distinct estimates derived from them. Next, the study shows that the current standard practice of singling …

Exploring The Divergent Social Dimensions Of Ceo Narcissism On Internal Firm Outcomes, Andrew Brandon Blake

Graduate Theses and Dissertations

In this study, I move away from the common clinical conception of narcissism in management to a novel two-dimensional concept and measurement of narcissism. Because these dimensions are shown to have divergent motives, goals, social strategies, and behaviors, I theorize that these differences in narcissism will have diverging effects on the firm. Then, I shift the conceptual focus of CEO narcissism research from the CEO as an agentic decision-maker seeking external praise for firm consequences to an implicit social strategist who prioritizes short-term interpersonal interactions in service of narcissistic supply. I examine four internal outcomes likely to be influenced by …

Associations Between Instagram Addiction, Academic Performance, Social Anxiety, Depression, And Life Satisfaction Among University Students, Behzad Foroughi, Mark D. Griffiths, Mohammad Iranmanesh, Yashar Salamzadeh

Research outputs 2014 to 2021

The use of social networking sites (SNSs) has become increasingly popular. Although several studies have been carried out on the addictive use of SNSs such as Twitter and Facebook, there is little research on Instagram addiction and its drivers. The present study investigated the association between students’ needs and Instagram addiction by incorporating physical activity as a moderator among 364 university students. Additionally, the associations between Instagram addiction, academic performance, depression, social anxiety, and life satisfaction were investigated. The results showed that recognition needs, social needs, and entertainment needs all contributed to Instagram addiction. However, information needs were not a …

Neural-Progressive Hedging: Enforcing Constraints In Reinforcement Learning With Stochastic Programming, Supriyo Ghosh, Laura Wynter, Shiau Hong Lim, Duc Thien Nguyen

Research Collection School Of Computing and Information Systems

We propose a framework, called neural-progressive hedging (NP), that leverages stochastic programming during the online phase of executing a reinforcement learning (RL) policy. The goal is to ensure feasibility with respect to constraints and risk-based objectives such as conditional value-at-risk (CVaR) during the execution of the policy, using probabilistic models of the state transitions to guide policy adjustments. The framework is particularly amenable to the class of sequential resource allocation problems since feasibility with respect to typical resource constraints cannot be enforced in a scalable manner. The NP framework provides an alternative that adds modest overhead during the online phase. …

Towards Pedagogy Supporting Ethics In Modelling, Marie Oldfield

Journal of Humanistic Mathematics

Education for concepts such as ethics and societal responsibility that are critical in building robust and applicable mathematical and statistical models do currently exist in isolation but have not been incorporated into the mainstream curricula at the school or university level. This is partially due to the split between fields (such as mathematics, statistics, and computer science) in an educational setting but also the speed with which education is able to keep up with industry and its requirements. I argue that principles and frameworks of socially responsible modelling should begin at school level and that this would mean that ethics …

The Existence Of Indonesian Islamic Market Stocks During The Covid-19 Pandemic, Febryna Rizka Pratiwi, Nur Fatwa Dr.

Journal of Strategic and Global Studies

Covid-19 For Crowdfunding: Catalyst Or Deterrent? Evidence From Russia, Evgeny Torkanovskiy, Alexander Voinov

The Indonesian Capital Market Review

This paper explores the impact of the COVID-19 pandemic on crowdfunding by analyzing a 2-year sample of 7,024 rewards-based crowdfunding campaigns on the two major Russian platforms. The study employs a digital methods approach to demand and supply and multiple regression analysis. The findings show that COVID-19 and the associated lockdown had no immediate and straightforward effect on the crowdfunding sector, neither on backers nor on campaigns’ initiators. Thus, the crowdfunding sector unlike some other investment classes remains resilient to the global pandemic. Beyond that, empirical analysis revealed the undescribed phenomenon of sponsors’ readiness to finance projects being highly seasonal …

Analyzing The Relationship Between Return And Trading Volume In Relation To Cross-Sectional Absolute Deviation (Csad) In Order To Detect Herding Behavior In Indonesia Emerging Stock Market, Helma Malini, Annisa Dipa Sakliana

The Indonesian Capital Market Review

Investor herding behavior is a primary source of speculative bubbles since it implies that investors make identical trading decisions, which can lead to stock prices deviating from their underlying worth. The goal of this study is to detect herding behavior in the Indonesian stock market between 2016 and 2021. The relationship between return and trading volume, known as Cross Sectional Absolute Deviation, is used to assess herding behavior (CSAD). Time-series regression and quantile regression analysis will be employed as data analytic techniques in this study to investigate herding behavior under various market scenarios. Herding behavior is evident in the Indonesian …

Bank Ownership And Decline In Loan Growth Due To The Pandemic, Ruthana Bitia, Zuliani Dalimunthe

The Indonesian Capital Market Review

This study aims to analyze the effect of bank ownership structure on loan growth before and during the pandemic. Specifically, we developed four models to capture different loan types provided in the Indonesian banking system; working capital, investment, consumer, and total loan growth. This study used 150 observations of commercial banks for 2019 (before the pandemic) and 2020 (during the pandemic). We conducted the regression method to test hypotheses. The main finding of this study was that foreign banks’ consumer credit growth significantly lower than domestic banks. Similar findings occurred for other types of loans, and this conclusion has controlled …
