Development Of Reduced Cementitious Materials Concrete (Rcmc) Mixtures For Bridge Decks And Rails, Soumitra Das

Department of Construction Engineering and Management: Dissertations, Theses, and Student Research

Right after construction, drying shrinkage of restrained concrete bridge decks and rails causes early-age cracking that eventually leads to delamination and spalling of concrete due to insertion of water and chemicals, and corrosion of reinforcing steel. The main objective of this research is to control early-age shrinkage cracking by reducing cementitious material content in the bridge deck and rail concrete mixtures. Several reduced cementitious materials concrete (RCMC) mixtures were developed by optimizing aggregate particle packing and conducting overall performance evaluation. This evaluation was carried out in three phases: The first phase investigated the feasibility of new RCMC mixtures by testing …

Coverage Error Properties Of Smartphone And Smartphone Operating System Ownership On Web Surveys: A Total Survey Error Perspective, Angelica Phillips

Department of Sociology: Dissertations, Theses, and Student Research

While smartphone ownership rates near 90% of the US population, differences in the types of people who do or do not own smartphones may contribute to coverage error biases within smartphone-exclusive web surveys. Therefore, understanding the predictors of smartphone ownership is of interest for survey researchers. Further, differential ownership of smartphone operating systems (OS) such as Android OS and iOS across groups of the population is also of interest for researchers who administer smartphone application surveys which are only compatible with one OS. However, little research has assessed differential rates of smartphone ownership over time nor has any research to …

A Case For Friendship: A Mixed Methods Investigation Of Close Friendships In Adulthood, Grace Kelly

Department of Sociology: Dissertations, Theses, and Student Research

Social connections profoundly impact mental and physical health, identity development, and overall well-being. The landscape of personal relationships has changed dramatically over the past decades. Formalized connections and older social structures are evolving (Smock and Schwartz 2020). Loneliness and social isolation are at epidemic proportions and rising, posing widespread societal consequences (Buecker et al. 2021; Cacioppo and Cacioppo 2018). Sociologists have studied relationships like kinship and romantic partnership extensively but have devoted substantially less attention to friendship as a means of providing connection (Eve 2002). My dissertation investigates the importance of platonic friendship bonds in adulthood and explores how these …

Between the Google Assistant and Amazon Alexa, nearly 1 billion people around the world use personal assistant devices daily. These devices are able to store information from our private conversations in order to make the devices more user friendly by targeting advertisements that relate to our interests. But what happens if our private conversations are stored for more than the above-mentioned purposes? This paper will examine a series of hypotheticals which involve devices, such as the Google Assistant, specifically relating to the devices’ audio recording capabilities. Not only will this paper point out the gaps in our current insider trading …

Breaking Up Mergers After The Fact: Opportunities And Problems, Stanley M. Besen, Philip L. Verveer

UC Law Business Journal

Antitrust authorities in both the United States and Europe have recently shown an increased interest in reviewing past mergers with the objective of possibly requiring mergers to be undone if they turned out to be anticompetitive. In this Article, we reach five main conclusions. First, analyzing the effects of past mergers is unlikely to be straightforward because it will be difficult to disentangle the competitive effects of a merger from other factors in the markets served by the merged firms. Second, even divestitures that were required before mergers had been consummated were complicated to bring about and there is evidence …

The Effects Of Temperature And Flooding Duration On The Structure And Magnitude Of A Floodplain Prey Subsidy, Ryan J. Rezek, Jordan A. Massie, James A. Nelson, Rolando O. Santos, Natasha M. Viadero, W. Ryan James, Ross E. Boucek, Jennifer S. Rehage

Marine Science

Riverine floodplains serve as an important link between terrestrial and aquatic systems, as the rising and falling of water drive spatial food web subsidies that are critical to the functioning and stability of ecosystems. As these systems are increasingly impacted by hydrological alterations and climate change, it is important to understand how floodplain spatial food web subsidies may respond to changing environmental conditions.

Here, we examine the interannual variation in the structure of a sunfish (Lepomis spp.) prey subsidy from freshwater marshes into the mangrove-lined creeks of Rookery Branch in the Florida Coastal Everglades that occurs during seasonal dry downs. …

On The Variability Of In Situ Surface Layer Refractivity Measurements, Douglas M. Pastore, Ryan T. Yamaguchi, Qing Wang, Erin E. Hackett

Marine Science

Direct measurements of profiles of atmospheric properties near the ocean surface and within the marine atmospheric surface layer often contain a large degree of variability. The variability observed can be explained by numerous technical and natural reasons such as the temporal variability over the time span a profile is measured (unsteadiness in the mean), spatial variations (inhomogeneity), turbulent fluctuations, and measurement uncertainty. In this study, we explored the observed variability in vertical distributions of refractive index measured with a tethered-balloon-based marine atmospheric profiling system (MAPS). MAPS profiled the atmosphere from approximately 0.5 to 50 m, with instantaneous (order 1 s) …

Biocompatibility and the ability to mediate the appropriate flux of ions, urea, and uremic toxins between blood and dialysate components are key parameters for membranes used in dialysis. Oxone-mediated TEMPO-oxidized cellulose nanomaterials have been demonstrated to be excellent additives in the production and tunability of ultrafiltration and dialysis membranes. In the present study, nanocellulose ionic liquid membranes (NC-ILMs) were tested in vitro and ex vivo. An increase in flux of up to two orders of magnitude was observed with increased rejection (about 99.6%) of key proteins compared to that of polysulfone (PSf) and other commercial membranes. NC-ILMs have a sharper …

The Implications Of Firms' Derivative Usage On The Frequency And Usefulness Of Management Earnings Forecasts, John L. Campbell, Sean Shun Cao, Hye Sun Chang, Raluca Chiorean

Research Collection School Of Accountancy

We investigate how firms' use of derivatives impacts voluntary disclosure and offer four main findings. First, we find that when firms begin using derivative instruments, they increase the frequency of management earnings forecasts. Second, using path analysis, we find a direct link between derivative usage and forecast frequency, as well as an indirect link through reduced earnings volatility. Third, we find that CEOs with more pronounced career concerns increase forecast frequency only when derivatives make earnings easier to forecast and find no evidence that investor demand drives the decision to provide a forecast. These results suggest that the primary mechanism …

Perceptions Of Elementary School Principals Regarding Strategies To Build Trust Among Staff To Support Positive Change, Laurel Cole

Doctor of Education Program Dissertations

Trust is essential between elementary school principals and teachers, for it is a necessary ingredient in well-functioning organizations, especially schools. The problem addressed in this phenomenological study was the lack of practical strategies for principals to build trust with teachers effectively and efficiently to facilitate positive change and, ultimately, to support student achievement. The purpose of this qualitative phenomenological study was to understand how elementary school principals can quickly build trust with their teachers to facilitate positive change. Through the literature review, the researcher examined historical definitions of trust and early trust studies, the creation of trust and strategies for …

The Finance And Economics Women’S Network (Few): Encouraging And Engaging Women In Undergraduate Programs, Joy Buchanan, Darwyyn Deyo

Faculty Research, Scholarly, and Creative Activity

We describe a novel intercollegiate resource for engaging more undergraduate women in finance and economics programs. In response to the gender gap in undergraduate studies, we developed the Finance and Economics Women’s Network (FEW) to support women majoring in finance and economics through FEW clubs. These clubs provide professional skill development and visibility for women in these professions through speaker events. Students run FEW clubs, and faculty advisors and community professionals support them. We also conducted a descriptive survey of students and report the responses. Finally, we provide a constitution template to facilitate the creation of FEW clubs.

Numerical Modeling Of Rock Blocks With Nonpersistent Rough Joints Subjected To Uniaxial Compressive And Shear Loadings, Mostafa Asadizadeh, Mahdi Moosavi, Mohammad Farouq Hossaini, Ahmadreza Hedayat, Taghi Sherizadeh, Hossein Masoumi

Mining Engineering Faculty Research & Creative Works

Characterizing the mechanical behavior of jointed rocks is important to understand the behavior of structures in rock masses. Jointed rocks can be composed of persistent and nonpersistent joints where the impact of nonpersistent joints requires careful consideration for an accurate rock mass mechanical characterization. Most previous investigations into nonpersistent jointed rocks focused on joints with smooth surfaces, and a few experimental studies focused on nonpersistent rough joints and nothing specific has been reported numerically. Therefore, this study investigated several synthetic jointed rocks with nonpersistent rough joints numerically under uniaxial compressive and shear loadings. The PFC2D-based synthetic rock mass (SRM) approach …

Evolution Mechanism Of Grain Orientation And Texture Distribution Of Ti-6.5al-3.5mo-1.5zr-0.3si Alloy Under Electroshocking Treatment, Jian Zhou, Chang Liu, Yaya Wu, Lechun Xie, Fei Yin, Dongsheng Qian, Yanli Song, Liqiang Wang, Lai-Chang Zhang, Lin Hua

Research outputs 2022 to 2026

It is well known that the mechanical properties of Ti-6.5Al-3.5Mo-1.5Zr-0.3Si are closely related to its microstructure and texture. In this work, a novel treatment of electroshocking treatment (EST) was adopted to optimize the microstructure and improve the mechanical properties of this titanium alloy. The grain orientation, texture, and mechanical properties of Ti-6.5Al-3.5Mo-1.5Zr-0.3Si alloy under EST were characterized and analyzed. With the increase of EST time to 0.04 s, the resultant acicular secondary αs shows a tendency of spheroidization and the increase in grain diameter, which leads to a little decrease in hardness and yield strength. The increase in EST time …

Ocean Connectivity And Habitat Characteristics Predict Population Genetic Structure Of Seagrass In An Extreme Tropical Setting, Udhi E. Hernawan, Kor-Jent Van Dijk, Gary A. Kendrick, Ming Feng, Oliver Berry, Christopher Kavazos, Kathryn Mcmahon

Research outputs 2022 to 2026

Understanding patterns of gene flow and processes driving genetic differentiation is important for a broad range of conservation practices. In marine organisms, genetic differentiation among populations is influenced by a range of spatial, oceanographic, and environmental factors that are attributed to the seascape. The relative influences of these factors may vary in different locations and can be measured using seascape genetic approaches. Here, we applied a seascape genetic approach to populations of the seagrass, Thalassia hemprichii, at a fine spatial scale (~80 km) in the Kimberley coast, western Australia, a complex seascape with strong, multidirectional currents greatly influenced by extreme …

On Irs-Assisted Covert Communication With A Friendly Uav, Xiaobei Xu, Linzi Hu, Sha Wei, Yuwen Qian, Shihao Yan, Feng Shu, Jun Li

Research outputs 2022 to 2026

Driven by the rapidly growing demand for information security, covert wireless communication has become an essential technology and attracted tremendous attention. However, traditional wireless covert communication is continuously exposing the inherent limitations, creating challenges around deployment in environments with a large number of obstacles, such as cities with high-rise buildings. In this paper, we propose an intelligent reflecting surface (IRS)-assisted covert communication system (CCS) for communicating with a friendly unmanned aerial vehicle (UAV) in which the UAV generates artificial noise (AN) to interfere with monitoring. Furthermore, we model the power of AN emitted by the UAV using an uncertainty model, …
