Managing Employees’ Use Of Mobile Technologies To Minimize Work-Life Balance Impacts, Suprateek Sarker, Saonee Sarker, Xiao Xiao, Manju Ahuja

Faculty and Staff Scholarship

Organizations recognize that employees’ use of mobile technologies improves productivity. Yet there is concern that mobile usage can impact employees’ work-life balance (WLB). In this article, we report on the undesirable impacts on WLB and offer a framework and a set of strategies for managing WLB. We propose that there is a continuum of WLB perceptions, with some seeing work and personal life as separate domains, others viewing work as overlapping with personal life and yet others perceiving the two domains as integrated

The Effects Of Growth Hormone On Primary Bovine Mammary Cell Models, Lisa Mcdonnell

Master's Theses

The ability of exogenous growth hormone (GH) to increase milk yield through insulin-like growth factor-1 (IGF-I) in dairy cows is well characterized. However, recent studies utilizing mammary epithelial cell lines indicate a direct effect of GH on mammary epithelial cells (MEC). To test if these observations are relevant in vivo and if this response differs between dairy breeds, three mammary models were utilized. Mammary explants from a lactating Jersey cow were cultured in classical lactogenic media (dexamethasone, insulin, and prolactin) with 0 or 10 ng/mL of recombinant bovine GH for 12h. Primary MEC from lactating Holstein and Jersey cows were …

Effects Of Seawater On The Mechanical Behavior Of Composite Sandwich Panels Under Monotonic Shear Loading, Thomas Robert Woo

Master's Theses

Abstract

Salt water environments are very harsh on materials that are used within them. Many issues are caused by either corrosion and/or internal degradation to the materials themselves. Composites are better suited for this environment due to their high strength to weight ratios and their corrosion resistance, but very little is known about the fracture mechanics of composites. The goal of this study is to gain a better understanding for the behavior of a composite boat hull under a shear loading, similar to the force water applies on the hull as the boat moves through the water; then attempt to …

Bioflocculation Of Wastewater Treatment Pond Suspended Solids, Louis Lefebvre

Master's Theses

Bioflocculation of Wastewater Treatment Pond Suspended Solids

Louis Lefebvre

Wastewater treatment lagoons and high rate algae ponds (HRAPs) can provide cost effective wastewater treatment, but they commonly have high effluent concentrations of total suspended solids (TSS). In this thesis algae pond effluent was treated in a beaker testing apparatus (mixed and aerated) with various mixtures of activated sludge and primary effluent simulating differing activated sludge aeration basin compositions then was allowed to settle to assess settleability. Conventionally, microalgal suspended solids are removed by chemical coagulation followed by separation methods that often have a high cost relative to the low cost …

Performance Of A Wastewater Treatment Pond System With Microfiltration, Eric Todd Martin

Master's Theses

ABSTRACT

PERFORMANCE OF A WASTEWATER TREATMENT POND SYSTEM WITH

MICROFILTRATION

Eric Martin

The Woodlands Wastewater Treatment Plant (WWWTP) treats wastewater from the Woodlands housing community near Nipomo, California. The treated effluent is recycled for irrigation of a golf course within the community. The treatment facility consists of three facultative ponds in series followed by a microfiltration system and chlorine disinfection. Microfiltration of wastewater pond effluent is a fairly new, and potentially challenging, application of microfiltration. This thesis describes the operating conditions and behavior of the WWWTP pond system followed by a microfiltration system for the purpose of producing recyclable water …

Amaethon – A Web Application For Farm Management And An Assessment Of Its Utility, Tyler Yero

Master's Theses

Amaethon is a web application that is designed for enterprise farm management. It takes a job typically performed with spreadsheets, paper, or custom software and puts it on the web. Farm administration personnel may use it to schedule farm operations and manage their resources and equipment. A survey was con- ducted to assess Amaethon’s user interface design. Participants in the survey were two groups of students and a small group of agriculture professionals. Among other results, the survey indicated that a calendar interface inside Amaethon was preferred, and statistically no less effective, than a map interface. This is despite the …

The Impact Of Outward Remodeling On Vasodilation In Skeletal Muscle Resistance Arteries, Ryan Robert Gallagher

Master's Theses

Peripheral arterial occlusive disease (PAOD) is an ischemic disease characterized by narrowing of the peripheral arteries due to the accumulation of atherosclerotic plaque in the inner lining of the vessels, which disrupts blood flow to downstream tissues. Blood can be redirected into collateral vessels, natural bypasses around arterial occlusions, causing shear-induced outward remodeling of the vessels. The enlarged vessels facilitate transfer of increased blood flow to downstream tissues. The remodeling process, however, may impair vasodilation, which in turn may cause or contribute to intermittent claudication- transient pain brought on by locomotion. To stimulate the growth of collateral arteries, the femoral …

Contemporary Us-American Satire And Consumerism (Crews, Coupland, Palahniuk), J.C. Lee

CLCWeb: Comparative Literature and Culture

In her article "Contemporary US-American Satire and Consumerism (Crews, Coupland, Palahniuk)" J.C. Lee focuses on contemporary satire's potential (or lack thereof) for change, reform, or rebellion through an investigation of works by Harry Crews, Douglas Coupland, and Chuck Palahniuk, all of which target consumerism. The said writers employ satire not to initiate rebellion or cultural change, but to reflect the problematic role of institutions in modern life and, in turn, the potential, even hope, for personal growth. Lee's analysis of texts by Crews, Coupland, and Palahniuk is intended to question satire's potential as a form of cultural critique and institutional …

Population Dynamics In Predynastic Upper Egypt: Paleodemography Of Cemetery Hk43 At Hierakonpolis, Ernest King Batey Iii

Graduate Theses and Dissertations

The site of Hierakonpolis is considered to have played an important role in the development of the Egyptian state, which formed at end of the fourth millennium BC. Archaeological evidence suggests that, for the Middle and Late Predynastic periods (ca. 3900-3200 BC), Hierakonpolis may be characterized as having experienced the following: a growth in both settlement and population size, an increased reliance on cereal agriculture, development of craft specialization, and the presence of a Social hierarchy as interpreted from an observed increase in the differentiation of mortuary behavior. Historical data suggest that these Social and economic changes would have affected …

Synthesis And Characterization Of Nanoscale Fluorescent Polymer Films, Maryus Chyasnavichyus

All Dissertations

Performance of the chemical sensing devices is based sensitivity to the targeted analytes and accuracy of the measurements. Of many different types of chemical sensors, fluorescence based sensing devices draw much attention as efficient yet small and straightforward devices, capable of detection of various analytes at extremely small quantities.
Polymeric materials provide support for the fluorescent materials and usually serve as a host for the chromophores, protecting them from harsh environments, and serve as a transport media for the analyte.
In the present study thin fluorescent polymer films, sensitive to the environment are synthesized and studied. Poly(glycidyl methacrylate) was used …

Induced Elastic Matrix Synthesis Within 3-Dimensional Collagen Constructs, Lavanya Venkataraman

All Dissertations

Elastin, a primary component of elastic arteries, maintains structural stability of the cyclically recoiling artery, and critically regulates vascular cell behavior. Accelerated degradation of elastic matrix, such as that seen in vascular pathologies like abdominal aortic aneurysms (AAA), can therefore severely compromise vessel homeostasis. Tissue engineering and in-situ matrix repair strategies evaluated so far are primarily limited in inducing adult vascular cells to replicate the complex elastic matrix assembly process, and restore lost matrix integrity. Previously, our lab established the elastogenic benefits of concurrent delivery of TGF-β1 and HA-oligomers (together termed elastogenic factors, EFs), within 2D cultures of rat aortic …

Sensitivity Analysis In Magnetic Resonance Elastography And A Local Wavelength Reconstruction Based On Wave Direction, Christopher Gillam

All Dissertations

or the detection of early stage cancer. MRE utilizes interior data for its inverse problems, which greatly reduces the ill-posedness from which most traditional inverse problems suffer.
In this thesis, we first establish a sensitivity analysis for viscoelastic scalar medium with complex wave number and compare it with the purely elastic case. Also we estimate the smallest detectable inclusion for breast and liver, which is about twice larger than using the purely elastic model. We also found the existence of optimal frequency (50 Hz) that maximizes the detectability when the Voigt model is used.
Second, we propose a local wavelength …

Custom And The Rule Of Law In The Administration Of The Income Tax, Lawrence Zelenak

Duke Law Journal

From the early years of the federal income tax to the present, the Internal Revenue Service (IRS) has engaged in what might be termed "customary deviations" from the dictates of the Internal Revenue Code, always in a taxpayer-favorable direction. A prominent current example is the IRS's "don't ask, don't tell" policy with respect to employee-retained frequent flier miles; in a 2002 announcement (which, as of 2012, is still in force), the IRS indicated that such miles were technically within the scope of the statutory definition of gross income, but that the IRS had no intention of enforcing the law. This …

Custom, Contract, And Kidney Exchange , Kieran Healy, Kimberly D. Krawiec

Duke Law Journal

In this Essay, we examine a case in which the organizational and logistical demands of a novel form of organ exchange (the nonsimultaneous, extended, altruistic donor (NEAD) chain) do not map cleanly onto standard cultural schemas for either market or gift exchange, resulting in sociological ambiguity and legal uncertainty. In some ways, a NEAD chain resembles a form of generalized exchange, an ancient and widespread instance of the norm of reciprocity that can be thought of simply as the obligation to "pay it forward" rather than the obligation to reciprocate directly with the original giver. At the same time, a …

Teaching Accessibility And Design-For-All In The Information And Communication Technology Curriculum: Three Case Studies Of Universities In The United States, England, And Austria, Paul Ryan Bohman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Digital technologies allow people with disabilities to participate independently in society in ways they never could before. The full realization of these new opportunities remains elusive, though, because working professionals in the information and communication technology (ICT) field rarely receive adequate training in how to make digital ICT accessible to people with disabilities. Adding accessibility to the university ICT curriculum can help create a critical mass of ICT professionals with accessibility awareness and expertise to finally realize the full accessibility potential of digital technologies. This dissertation provides a rich informational context from which ICT curriculum leaders can decide how to …

Modulation Of The Host Response To Tacaribe Arenavirus Infection In Ag129 Mice By My-24, Eric Sefing

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

MY-24 is a new antiviral compound recently shown to protect immunocompromised mice from lethal challenge with Tacaribe virus (TCRV). Tacaribe virus is incapable of causing disease to humans, but is closely related to the highly pathogenic New World arenaviruses that cause often-fatal viral hemorrhagic fever syndromes. Remarkably, MY-24 prevents mortality without reducing virus burden in the circulation or tissues. To investigate the mechanism by which MY-24 protects AG129 mice against Tacaribe virus infection, we first characterized the natural history of disease in the model with an emphasis on host immune response and blood vessel function to establish the best times …

Design And Construction Of A Tunable Light Source With Light Emitting Diodes For Photosynthetic Organisms, Nathan Phillipps

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis describes and documents the design and construction of a light source which is tunable and has the ability to mimic the spectral output of the sun in the photosynthetic active radiation range (400 - 700 nm). To adjust the spectral output at different wavelengths different types of LEDs were chosen and combined. This thesis describes the design, construction, testing, and suggestions for further improvements to this light source. The light source is comprised of 900 LEDs with 26 different peak wavelengths within the photosynthetically active radiation range. The light source is made tunable through the use of a …

Medical Professionalism: An Expiremental Look At Physicians' Facebook Profiles, Joseph Wright Clyde

Undergraduate Honors Capstone Projects

Use of social networking services (SNS) is on the rise. While many users sign in for personal purposes, it is not uncommon for professionals to connect over SNSs with clients, students, and patients. The present study was concerned with examining a particular group of professionals, medical doctors, and how their profiles on an SNS site related to potential patient's impressions of professionalism. Participants recruited from Utah State University (USU; n = 253) and through Survey Monkey (n = 39) were randomized to view one of six vignette Facebook profiles. Profiles were populated with solely professional material or personal material …

Observational Research In A Marketing Classroom: A Guidebook, Kristen Winterton

Undergraduate Honors Capstone Projects

Qualitative research plays an integral part in marketing research (Denzin and Lincoln, 1998). In fact, a search of the website for the American Marketing Association for the term “qualitative research” reveals literally hundreds of documents (white papers, case studies, etc) discussing methods of conducting observational research, examples of observational research studies, and the importance of observational research in marketing. Interestingly, though qualitative methods are used frequently by practitioners, they receive very limited attention in marketing textbooks. This seems particularly true of observation research, which is among the least expensive and easily conducted qualitative methods (Mann, 2003). The purpose of this …

Understanding Antiwar Activism As A Gendering Activity: A Look At The U.S.’S Anti-Vietnam War Movement, Say Burgin

Journal of International Women's Studies

Research into the gendered nature of war experiences has provided rich ways of understanding how gender constructs society and the nation. Scholarship on peace activism and gender has deepened our knowledge of women’s roles within warring societies and the ways women have understood themselves as promoters of peace. While much of this research asks how antiwar activities and war are predicated upon dominant gender ideals and focuses in particular on women’s experiences, this article aims to explore how some wartime events, specifically antiwar activism, constitutes or reconstitutes gender. Focusing on the United States’ anti-Vietnam War history, I examine how activists …

Non-Binary Gender Concepts And The Evolving Legal Treatment Of Uk Transsexed Individuals: A Practical Consideration Of The Possibilities Of Butler, Alex Harris

Journal of International Women's Studies

This essay seeks to bridge the gap between the UK legal system’s treatment of transsexuals and post-structuralist gender theory. It argues that whilst the greater representation of transsexuals in UK legal discourse embodied in the Gender Recognition Act is a positive move forward in terms of classic liberal notions of human rights and in its acceptance of transsexuals as proper subjects before the law, it nonetheless represents an essentialist conception of transsexuals; requiring them to ‘fit’ within binary categories of male and female. It is argued that post-structuralist thought regarding gender can illuminate some of the problems inherent within the …
