Exploring The Impact Of Technology Capabilities On Trust In Virtual Teams, Deepak Khazanchi

Information Systems and Quantitative Analysis Faculty Publications

Purpose – In an environment of constant technological change, the use of virtual teams has become commonplace for many organizations. Virtual teams (VTs) bring together dispersed individuals with varying knowledge and skill sets to accomplish tasks. VTs rely heavily on information technology as the medium for communication and coordination of work. The issue of establishing and maintaining trust in VTs poses challenges for these dispersed workers. Previous research has established that higher trusting teams have better cooperation and experience improved outcomes. We hope to contribute to the literature on trust in VTs by exploring how technology can facilitate high trusting …

"I Viewed Them Sick": Photography And Addiction Medicine As Activism During The "Speed Freak" Crisis Of The Long 1960s, Hannah Zornow Alter

Yale Medicine Thesis Digital Library

“Speed freak” was a pejorative term that emerged in the late 1960s to describe young people who binged on amphetamines, often by injection. The accessibility of amphetamines during the 1960s and early 1970s coupled with the emergence of a radical youth movement produced this distinctive subculture. This thesis will address responses to this drug crisis in two parts, from the perspective of two activists working in very different fields. In 1971, Larry Clark, a photographer, and David Smith, a physician, each published their seminal works on “speed freak” culture. Separated by half a country, they had enmeshed themselves in communities …

Parental Perspectives On Myopia In An Urban Chinese Population, Wendy Li

Yale Medicine Thesis Digital Library

In this study, we aimed to understand how Chinese parents view myopia, including causes, progression, and treatment. We performed a cross-sectional study from July 2016 to August 2016 at Peking University 3rd Hospital in Beijing, China. Parents of myopic children completed a questionnaire including sociodemographics and Likert-style questions assessing perspectives on myopia. We employed logistic regression models to analyze relationships between responses and demographic data/degree of myopia. 109 parents completed the survey. Of these, 97 responses were included in the analysis. Almost all parents surveyed (97.9%) found their child’s myopia concerning and believe myopia is dangerous to their child’s vision. …

Orally-Dosed Citalopram Stimulates Small Intestinal Mucosal Growth, Lucy Zhang

Yale Medicine Thesis Digital Library

Parenterally-administered selective serotonin reuptake inhibitors (SSRI), such as citalopram, increase intestinal mucosal absorptive surface by day 7 of treatment. We hypothesized that enteral citalopram would also induce intestinal mucosal growth, thus allowing for therapy with an oral agent. In the study’s first phase, C57BL/6 mice received peanut butter (PB) pellets containing 10, 50, or 100 mg/kg/day citalopram for 7 days; or 25 mg/kg/day citalopram for 14 or 21 days; or plain PB pellets for 7, 14, or 21 days. In the second phase, C57BL/6 mice received 0, 10, 25, or 50 mg/kg/day citalopram in drinking water for 2, 3, 6, …

The Force Of Absent Things: Hiv/Aids, Pepfar Vietnam, And The Afterlife Of Aid, Alfred Montoya

Sociology & Anthropology Faculty Research

This article examines emerging strategies employed by nongovernmental organizations working in HIV/AIDS prevention and control in Vietnam that have been put to work in the recent past in the context of precipitous declines in US funding for such work through the President’s Emergency Plan for AIDS Relief (PEPFAR). These strategies foreground specific personalities in an instrumentalization of experience, expert knowledges, and identity in a delicate balance between projecting strength and indicating urgent need. These strategies are played out in the realm of social media, facilitated through information communications technologies (ICTs) that are quickly restructuring forms of sociality and the tradecraft …

Networked Human, Network’S Human: Humans In Networks Inter-Asia, E. Kerr, Connor Graham, Alfred Montoya

Sociology & Anthropology Faculty Research

This special issue explores the conceptions of the human that emerge out of the form and the design of information and communications technologies (ICTs). Geographically, our focus compares two countries with a relatively high level of ICT penetration—South Korea and Singapore—and two countries with a relatively low level—India and Vietnam. In each country we see how different forms of the human emerge, in part out of the ways in which technological infrastructure develop and intertwine with social order. In this introduction we reflect on the long genealogy of “human” and “humanity” and the more recent history of ICTs in Asia.

Adam Smith On The Future Of Experimental Evolution And Economics, Maria Pia Paganelli

Economics Faculty Research

Experimental evolution is difficult to apply to humans because of the need to study possible changes over many generations. A similar method, though, may see history as a substitute for experiments. The 18th century economist Adam Smith uses methods compatible with the logic of experimental evolution, through the assumption of human homogeneity and the study of history, to explain endogenous variations of preferences and institutions.

Adrenergic Stimulation In Acute Hyperglycemia: Effects On Cellular And Tissue Level Murine Cardiac Electrophysiology, Sridevi Thyagarajan

Theses and Dissertations--Biomedical Engineering

Cardiovascular complications associated with elevated levels of glucose in the blood (Hyperglycemia, HG) is a growing health concern. HG is known to be associated with a variety of cardiovascular morbidities including higher incidence of electrical disturbances. Although effects of chronic HG have been widely investigated, electrophysiological effects of acute hyperglycemia are relatively less known. Further, hyperglycemic effects on adrenergic response is not widely investigated. We used excised ventricular tissues from mice to record trans-membrane potentials during a variety of pacing protocols to investigate cellular/tissue level electrophysiological effects of acute hyperglycemia and adrenergic stimulation (1µM Isoproterenol, a β-adrenergic agonist). A custom …

Multimodal Noncontact Diffuse Optical Reflectance Imaging Of Blood Flow And Fluorescence Contrasts, Daniel Irwin

Theses and Dissertations--Biomedical Engineering

In this study we design a succession of three increasingly adept diffuse optical devices towards the simultaneous 3D imaging of blood flow and fluorescence contrasts in relatively deep tissues. These metrics together can provide future insights into the relationship between blood flow distributions and fluorescent or fluorescently tagged agents. A noncontact diffuse correlation tomography (ncDCT) device was firstly developed to recover flow by mechanically scanning a lens-based apparatus across the sample. The novel flow reconstruction technique and measuring boundary curvature were advanced in tandem. The establishment of CCD camera detection with a high sampling density and flow recovery by speckle …

Sleep And Thermoregulation: A Study Of The Effect Of Ambient Temperature Manipulation On Mouse Sleep Architecture, Asma'a A. Ajwad

Theses and Dissertations--Biomedical Engineering

Good quality sleep is essential for mental and physical health. Inadequate sleep impacts memory consolidation, learning and cognition, immune function, autonomic regulation, physical performance, and other vital functions. In many neurological disorders that are associated with sleep problems such as epilepsy and Alzheimer’s disease, changes in brain circuitry affect sleep-wake regulation mechanisms; this is reflected in anomalous sleep-wake architecture and usually accompanied by poor sleep depth. Thus, over many years, many approaches have been tried in humans and animal models with the goal of improving sleep quality. Unfortunately, each of those approaches comes with limitations or side effects. Thus, there …

Assessment Of Watershed Nutrient Loads And Effectiveness Of Best Management Practices, Saeid Nazari

Theses and Dissertations--Civil Engineering

Several methods have been developed for use in estimating the water quality loads associated with urban and agricultural landuses and practices. These include the use of sophisticated computer models, typically based on using pollutant loading and runoff functions, regression equations, load export coefficients (LECs), and event mean concentrations (EMCs). This research has examined the feasibility of using a simple EMC approach with the Kentucky Nutrient Model (KYNM). The thesis includes an extensive literature review of EMCs and a synthesis of recommended values for a range of typical urban and agricultural landuses. The thesis also includes an extensive literature review of …

Modeling And Mapping Location-Dependent Human Appearance, Zachary Bessinger

Theses and Dissertations--Computer Science

Human appearance is highly variable and depends on individual preferences, such as fashion, facial expression, and makeup. These preferences depend on many factors including a person's sense of style, what they are doing, and the weather. These factors, in turn, are dependent upon geographic location and time. In our work, we build computational models to learn the relationship between human appearance, geographic location, and time. The primary contributions are a framework for collecting and processing geotagged imagery of people, a large dataset collected by our framework, and several generative and discriminative models that use our dataset to learn the relationship …

Jak/Stat Signaling Regulates Gametogenesis And Age-Related Reproductive Maintenance, Michelle Suzanne Giedt

Theses and Dissertations--Biology

Cell signaling is central to integration of internal and external cues that regulate development and homeostasis. Most development is thought of as pre-adult, but limited developmental processes occur in adults. Gametogenesis incorporates elements of both these facets, with a distinct developmental plan for gamete synthesis which is regulated by integration of homeostatic inputs such as nutrient status, and environmental cues. Signaling pathways integrate and transduce information from these cues to evoke a response. A decline in homeostasis and subsequent cues occurs over time, in the case of reproductive tissues leading to a progressive loss of fertility. The Janus Kinase and …

Catastrophic Futures, Robby Hardesty

Theses and Dissertations--Geography

By means of a peculiar magic, insurance preserves the quantified value of capital through destructive, contingent events. The principal subjects of this project, global reinsurers, stand at the end of a long line of loss claims, holding capital together as forces threaten to tear it apart. The apocalyptic imaginaries of climate change portend events that will be increasingly destructive to capital, and insurers counter with new products and narratives. In examining reinsurers and the catastrophes they protect against, this project questions how novelty emerges from the eternal return of the same. I show how power is inscribed in the landscape, …

Determining Millennial Food Buying Preferences: Based On Product Marketing With “Buzzwords”, Victoria N. Hamilton

Theses and Dissertations--Community & Leadership Development

This research focuses on the importance on the Millennial Generation and their perceptions of food buzzwords. Since the Millennial Generation is the largest group purchasing and preparing their own foods, the food industry is becoming dependent on their buying preferences. A survey reflected the participants’ demographics and their buying preferences based on a series of food buzzwords when they are purchasing foods. Results show the Millennial Generation prefers “local” buzzwords. As the Millennial Generation continues to purchase foods for themselves and their families, it can be expected their choices will encourage others to do the same based on their family …

Fractionation Of Lignin Derived Compounds From Thermochemically Processed Lignin Towards Antimicrobial Properties, Luke A. Dodge

Theses and Dissertations--Biosystems and Agricultural Engineering

The overuse of antibiotics in agriculture is an emerging concern, due to their potential detrimental impact to the environment. This study focuses on exploring antimicrobial properties of lignin derived compounds. Lignin is of interest as a feedstock to replacing some petroleum-based chemicals and products because it is the most abundant source of renewable aromatic compounds on the planet. Two lignin rich streams, residues from the enzymatic hydrolysis of dilute acid and alkaline pretreated corn stover, were decomposed via pyrolysis and hydrogenolysis, respectively. The resulting liquid oils were subjected to sequential extractions using a series of solvents with different polarities. Chemical …

High Resolution Sensing Of Nitrate Dynamics In A Mixed-Use Appalachian Watershed: Quantifying Nitrate Fate And Transport As Influenced By A Backwater Riparian Wetland, Alexandria Kosoma Jensen

Theses and Dissertations--Biosystems and Agricultural Engineering

As harmful algal blooms begin to appear in unexpected places such as rivers in predominantly forested systems, a better understanding of the nutrient processes within these contributing watersheds is necessary. However, these systems remain understudied. Utilization of high-resolution water quality data applied to deterministic numerical modeling has shown that a 0.42% watershed area backwater riparian wetland along the Ohio River floodplain can attenuate 18.1% of nitrate discharged from local mixed-use watersheds and improves in performance during high loading times due to coinciding increased hydrological connectivity and residence times of water in these wetlands. Loading from the Fourpole Creek watershed was …

Valorization Of Proso Millet And Spent Grain For Extruded Snack Development, Joseph Woomer

Theses and Dissertations--Biosystems and Agricultural Engineering

Fast-paced lifestyles result in consumers replacing traditional meals with on-the-go snack foods. In general, snacks are higher in saturated fats and simple sugars, and pose health concerns for consumers, which prompts the need for healthy nutritious alternatives to common snacks. Proso millet is a nutritious, and fast growing gluten free cereal. Spent grain (SG), the main by-product of brewing and distilling, contains high amount of protein and insoluble fibers. This study utilized proso millet and spent grain in the production of an extruded expanded snack, demonstrating their appropriateness as an ingredient in food production.

The first objective of this study …

Determining Heat Production Of Black Solderi Fly Larvae, Hermetia Illucens, To Design Rearing Structures At Livestock Facilities, Travis Mceachern

Theses and Dissertations--Biosystems and Agricultural Engineering

Due to their small size and ectothermic biology, the heat production of insects and insect larvae is hard to quantify. However, knowing the amount of heat production, as well as ammonia production of insects may be beneficial for commercial production of valuable insect species. Black soldier fly larvae (BSFL) are of interest in the agricultural industry because they quickly consume organic waste and have high amounts of protein and fat in their bodies. It has been proposed that BSFL be used to manage livestock waste, while serving as a high-protein feed source for livestock animals. To efficiently rear BSFL, it …

The Role Of Pro-Inflammatory Mediators Ifnβ And Prostaglandin E2 In Suppression Of Innate Immunity To Listeria Monocytogenes, Michelle G. Pitts

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

As a foodborne pathogen, Listeria monocytogenes (Lm) encounters many barriers to invasion and dissemination in the host that may change the nature of host response. Lm has been most commonly studied using intravenous (i.v.) inoculation, however, a method that delivers a bolus of bacteria directly to the bloodstream. Thus, little is known about what systemic and local mediators are triggered during the natural course of infection and how these may impact susceptibility. Our laboratory used foodborne transmission of Lm in mice to assess whether the method of transmission and the specific organ microenvironment could affect infection-induced secretion of …

Studying Vascular Morphologies In The Aged Human Brain Using Large Autopsy Datasets, Eseosa T. Ighodaro

Theses and Dissertations--Neuroscience

Cerebrovascular disease is a major cause of dementia in elderly individuals, especially Black/African Americans. Within my dissertation, we focused on two vascular morphologies that affect small vessels: brain arteriolosclerosis (B-ASC) and multi-vascular profiles (MVPs). B-ASC is characterized by degenerative thickening of the wall of brain arterioles. The risk factors, cognitive sequelae, and co-pathologies of B-ASC are not fully understood. To address this, we used multimodal data from the National Alzheimer’s Coordinating Center, Alzheimer’s Disease Neuroimaging Initiative, and brain-banked tissue samples from the University of Kentucky Alzheimer’s Disease Center (UK-ADC) brain repository. We analyzed two age at death groups separately: < 80 years and ≥ 80 years. Hypertension was a risk factor in the < 80 years at death group. In addition, an ABCC9 …
