Designing Efficient And Equitable Freight Services Markets For Sustainable Economic Performance, Arim Park, Mark Rodgers, Soohyun Cho

American Business Review

Despite the indispensability of freight trucking services and truckers’ role as critical stakeholders in supply chains, relatively little attention has been paid to analyzing small independent truckers’ roles. Shippers often prefer working with larger trucking companies to the detriment of smaller independent truckers, who must grapple with an inherently disadvantageous job market. Furthermore, in the presence of uncertainty or peak demand periods, trucker shortages can pose significant economic challenges for shippers and downstream customers. In this paper, we propose an analytical framework to address these challenges in efforts to enhance the sustainability of the freight service industry. We formulate and …

Equity Returns Around Extreme Loss: A Stochastic Event Approach, Xiaomin Guo, Huijian Dong, Gary A. Patterson

American Business Review

We define an extreme loss event as a daily return at the left tail of negative two standard deviations of all daily returns for a specific stock. Prior studies focus on the relationship between extreme losses and specific anticipated announcements. Our study identifies the extreme loss events after they are randomly realized, and examines the return patterns of the equities in question on stochastic event setups. We investigate the daily returns of 2,651 stocks traded in the U.S. equity markets and identified 217,990 extreme loss events from the 1950s to early 2019. Our findings show that after an extreme loss, …

Firm Type And Unconditional Conservatism: The Indian Experience With Ifrs Convergence, Debarati Basu

American Business Review

This paper investigates how private and public firms vary with respect to unconditional conservatism in financial reporting in the pre and post IFRS worlds. I consider unconditional conservatism (UC) which pre-empts the more commonly studied conditional conservatism, private firms that are differently regulated, IFRS convergence instead of the more uniform IFRS adoption and an emerging market. Using a large Indian sample of 63,000 observations across more than 15,500 firms (~41% are private) over 10 years (2011-2020), I show that private firms are less unconditionally conservative than public firms. Also, contrary to literature, IFRS convergence increases conservatism in India and reduces …

From Hr Practices To Hr Performance: A Psychological Ownership Meta-Analysis Across Cultures, Franziska M. Renz

American Business Review

This study utilizes psychological ownership theory as theoretical framework to examine high-performance work practices, and attitudinal and behavioral performance as associations of psychological ownership on the population level. Psychological ownership describes a mindset which allows individuals to experience ownership feelings for a target (e.g., organization) regardless of legal ownership rights. Further, psychological ownership theory is integrated with and extended by contingency theory to analyze the moderation effects of societal culture. These effects have been assumed for over 30 years but hardly backed by empirical evidence from cross-cultural samples. Thus, this study analyzes data from 351,919 individuals who participated in 139 …

Urban Unemployment Duration Analysis In Post-Reform China, Soumyatanu Mukherjee, Soumya Roy

American Business Review

We link China’s accession to the WTO with the unemployment duration of urban jobseekers. Using data from the Rural Urban Migration in China (RUMiC) of a survey conducted in early 2008, we construct an inflow sample of those who started a period of joblessness between January 2002 and December 2007 to estimate the unemployment duration for local urban jobseekers. Deploying the Cox Proportional Hazards and Accelerated Failure Time models, we find reduced trade policy uncertainty significantly shortens unemployment duration, with hazard-rate varying across internal in-migrants and urban natives, due to variations in job accessibility and reservation wages.

Harnessing Social Media For Climate Action In Developing Countries: A Case Study Of Egypt, Nicolas Hamelin, Passant Halawa

Faculty Journal Articles

Like many developing nations, Egypt is facing a climate crisis due to its agricultural dependence and the Nile Delta’s vulnerability. Despite government plans for sustainable development, recent infrastructure projects have resulted in large-scale green space removal. Effective communication about environmental issues can spark pro-environmental behavior and citizen activism. This study explores social media’s potential to bridge this gap in Egypt. Utilizing Facebook AB testing with a limited budget, we reached a significant 2.3% of Egypt’s online population (nearly 2 million users). This study explored message framing, with findings showing that rational posts resonated best while fear appeals had minimal impact. …

Tarnished Glory: The Exclusion Of Buffalo Soldiers In World War I, David Michael Barron

Theses and Dissertations

This thesis examines the exclusion of the Buffalo Soldier regiments during World War I. Due to the rise of racial discrimination in the early twentieth century, the Buffalo Soldier regiments experienced violence with civilians while stationed in the United States. The violence experienced by African American soldiers would shape decisions that would ultimately impact their involvement in World War I. By examining evidence from their war record in previous conflicts and evidence from the racial violence that occurred while stationed in the US, this thesis will show that their exclusion in World War I was due to poor conduct perpetrated …

Theses and Dissertations

The purpose of this study was to examine leadership practices utilized by school administrators for discretionary discipline consequences that feed the school-to-prison pipeline. The researcher utilized a hermeneutic phenomenological approach to investigate factors that influence campus administrators’ decision to use of exclusionary discipline through a series of semi-structured interviews. Through data analysis, three themes emerged: (1) Principals’ Impact on Student Discipline (2) Principals’ Considerations Before Using Exclusionary Discipline (3) Principals Lack of Training.

Conditional Quantization For Uniform Distributions On Line Segments And Regular Polygons, Tsianna Danielle Dominguez

Theses and Dissertations

Quantization for a Borel probability measure refers to the idea of estimating a given probability by a discrete probability with support containing a finite number of elements. If in the quantization some of the elements in the support are preselected, then the quantization is called a conditional quantization. In this thesis, we have investigated the conditional quantization for the uniform distributions defined on the unit line segments and m-sided regular polygons, where m ≥ 3, inscribed in a unit circle.

Artificial Intelligence (AI) has advanced rapidly in the past two decades. Internet of Things (IoT) technology has advanced rapidly during the last decade. Merging these two technologies has immense potential in several industries, including agriculture.

We have identified several research gaps in utilizing IoT technology in agriculture. One problem was the digital divide between rural, unconnected, or limited connected areas and urban areas for utilizing images for decision-making, which has advanced with the growth of AI. Another area for improvement was the farmers' demotivation to use in-situ soil moisture sensors for irrigation decision-making due to inherited installation difficulties. As Nebraska …

Singing While Acting: A Mixed Methods Study Of Classical Singers’ Application Of The Chekhov And Meisner Acting Methods, Amy C. Johnson

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

When considering the minimal acting training incorporated into most voice performance programs, it is understandable why many singers struggle to balance vocal demands with acting demands. Furthermore, the expectations on singers to deliver authentic and nuanced performances are increasing as opera evolves. There is little in-depth understanding of classical singers’ experiences with applying specific acting techniques to their singing. There is also little information about how different acting methods may affect classical singing. This mixed methods collective case study aims to identify the impact of training in a specific acting method on classical singing. The qualitative strand focuses on the …

Exploring Affective Experiences Of Queer Individuals Navigating Relationships With Evangelical Parents, Grace Pappas

School of Social Work Faculty Publications and Presentations

An abundance of scholarship explores and discusses the process of queer identity development, including the experience of disclosing one’s queer identity, often referred to as coming out. Coming out to one’s parent(s) can be a challenging and complex experience for queer individuals, particularly for children from religious families. In this study, I explored the nuanced relationships between queer individuals and their Evangelical parents. I conducted qualitative interviews with nine participants. Using thematic analysis and Ahmed’s theory of affect and happy objects, I constructed four themes: (a) learning the affect queer carries, (b) feeling the affects of being queer, (c) how …

Development Of A Multi-Use Modular Microfluidic Platform Using 3d Printing, Carson Emeigh

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Microfluidic lab-on-a-chip (LoC) technology has driven numerous innovations due to their ability to perform laboratory-scale experiments on a single chip using microchannels. Although LoC technology has been innovative, it still suffers from limitations related to its fabrication and design flexibility. Typical LoC fabrication, with photolithography, is time consuming, expensive, and inflexible. To overcome the limitations of LoC devices, modular microfluidic platforms have been developed where multiple microfluidic modules, each with a specific function or group of functions, can be combined on a single platform. Modular microfluidics have overcome some of the limitations of LoC devices, but currently, their fabrication is …

Nineteen nonfiction books were chosen following selection methods described in previous literature. Books were individually analysed to see which of five categories they fit under, and insider/outsider status for each author and illustrator was recorded as well. All five types were found in the surveyed Chinese nonfiction picturebooks; however, none of the books encouraged readers to take action for social change. We also found slight variation in peritext usage between the insiders and outsiders for authors and illustrators. …

Age, Gender, And Sexual Orientation And Their Effects On Online Dating Motivations, Jenna Leigh Mcpherson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Online dating and dating apps are becoming more common as a means to meet a romantic or sexual partner (e.g. Rosenfeld, Thomas, & Hausen, 2019). Previous literature on the motivations for why people use dating apps and how they differ among participants of varying age, gender, and sexual orientation has not allowed for comparisons across these groups, or shows conflicting findings. In order to consolidate existing literature and further explore the topic, I conducted both a meta-analysis and meta-synthesis. The meta-analysis demonstrated a gender difference in the motivation of casual sex, such that men scored higher than women. The meta-synthesis …

Examining The Risks And Resilience Of Older Adults Living With Hiv/Aids: Qualitative Community-Based Participatory Research Studies In Southern Nevada, Brandon Ranuschio

UNLV Theses, Dissertations, Professional Papers, and Capstones

Since the height of the HIV pandemic in the 1980s, medical interventions have significantly increased the life expectancy of people living with HIV/AIDS (PLWH) and made HIV/AIDS a livable, chronic health condition. Because of this, PLWH have been living longer lives and thriving with the help of HIV sector healthcare and service providers. However, with their longer life expectancy, older PLWH have been experiencing other health challenges. One such challenge is the risk of developing HIV-Associated Neurocognitive Disorder (HAND), which is a condition that affects up to 50% of PLWH at some point in their lifetime, with middle-aged and older …
