Microfluidic Generated Egf-Gradients Induce Chemokinesis Of Transplantable Retinal Progenitor Cells Via The Jak/Stat And Pi3kinase Signaling Pathways, Uchenna J. Unachukwu, Moira Sauane, Maribel Vazquez, Stephen Redenti

Publications and Research

A growing number of studies are evaluating retinal progenitor cell (RPC) transplantation as an approach to repair retinal degeneration and restore visual function. To advance cell-replacement strategies for a practical retinal therapy, it is important to define the molecular and biochemical mechanisms guiding RPC motility. We have analyzed RPC expression of the epidermal growth factor receptor (EGFR) and evaluated whether exposure to epidermal growth factor (EGF) can coordinate motogenic activity in vitro. Using Boyden chamber analysis as an initial highthroughput screen, we determined that RPC motility was optimally stimulated by EGF concentrations in the range of 20-400ng/ml, with decreased stimulation …

Generations Apart: Exploring The Generation Gap In Theatre, Jesus Briones

Theses and Dissertations - UTB/UTPA

This thesis attempts to find relationships among three different ethnic groups (Jewish, Chinese, and Italian) presented in the following plays. First, there is an explanation of four different types of generation gaps that are discovered throughout the first play of examination, Fiddler on the Roof. There is a technology gap, a cultural gap, a religion gap, and an assimilation gap. Each of these gaps is present within Fiddler on the Roof and is varied throughout the remaining plays examined (Flower Drum Song and Over the River and Through the Woods). Each “gap” will be given an explanation and how it …

La Gente De Migración Y Acción: African Americans In Revolutionary Mexico 1880–1929, Alfredo Aguilar

Theses and Dissertations - UTB/UTPA

This thesis argues that Mexico historically presented African Americans with options to pursue freedom through outlets of migration (civil) and counter-violence (violent resistance). In addition, the thesis exhibits Mexico’s historical anti-slavery stance which reflects why Mexico was a viable place of relocation and resistance. Furthermore, it argues Mexico and the United States had roles in African Americans’ relation to Mexico and these endeavors of resistance. By using primary sources such as newspapers and government reports, the extent of propaganda methods and use becomes discernible. The objective is to highlight the international assistance Mexico provided towards African Americans, the U.S. role …

Efficient Privacy-Preserving Range Queries Over Encrypted Data In Cloud Computing, Bharath K. Samanthula, Wei Jiang

Computer Science Faculty Research & Creative Works

With the growing popularity of data and service outsourcing, where the data resides on remote servers in encrypted form, there remain open questions about what kind of query operations can be performed on the encrypted data. In this paper, we focus on one such important query operation, namely range query. One of the basic security primitives that can be used to evaluate range queries is secure comparison of encrypted integers. However, the existing secure comparison protocols strongly rely on the encrypted bit-wise representations rather than on pure encrypted integers. Therefore, in this paper, we first propose an efficient method for …

Computer Science Faculty Research & Creative Works

Trustworthy service composition is an extremely important task when service composition becomes infeasible or even fails in an environment which is open, autonomic, uncertain and deceptive. This paper presents a trustworthy service composition method based on an improved Cross generation elitist selection, Heterogeneous recombination, Cataclysmic mutation (CHC) Trustworthy Service Composition Method (CHC-TSCM) genetic algorithm. CHC-TSCM firstly obtains the total trust degree of the individual service using a trust degree measurement and evaluation model proposed in previous research. Trust combination and computation then are performed according to the structural relation of the composite service. Finally, the optimal trustworthy service composition is …

Elementary Implantable Force Sensor For Smart Orthopaedic Implants, Rebecca A. Wachs, David Ellstein, John Drazan, Colleen P. Healey, Richard L. Uhl, Kenneth A. Connor, Eric H. Ledet

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Implementing implantable sensors which are robust enough to maintain long term functionality inside the body remains a significant challenge. The ideal implantable sensing system is one which is simple and robust; free from batteries, telemetry, and complex electronics. We have developed an elementary implantable sensor for orthopaedic smart implants. The sensor requires no telemetry and no batteries to communicate wirelessly. It has no on-board signal conditioning electronics. The sensor itself has no electrical connections and thus does not require a hermetic package. The sensor is an elementary L-C resonator which can function as a simple force transducer by using a …

Something To Talk About:Lessons Of Language And Literacy From A Tutorial Pilot Program, Joanna Neel

Education Faculty Publications and Presentations

This article describes a study conducted to determine evidence of key variables of literacy development and language acquisition, based on tutor’s lessons focusing on books and conversations about books and tutee’s questions. During one semester, university students tutored students from third to fifth grade, creating learning communities incorporating language and literate conversations, discussions about learning, and thinking/ comprehension strategies into each tutorial session, based on the needs of each student, as determined by the homeroom teacher. Conversations about books and topics were determined by student interest. Tutors were prepared with eight preparation sessions. Tutors noted student literacy behaviors in journals, …

Segregation, Inequality, Demographic Change, And School Consolidation, William England, Edmund T. Hamann

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

We describe a rural/micropolitan example of the intertwining of school consolidation and demographic change with exacerbated segregation and inequality. To do this we consider Dawson County, Nebraska, which hosts the state's most Latino/a school district (Lexington) and which saw its number of schools decline from 37 to 19 during this century's first decade, and the number of local school districts lessened from 18 to 5. In particular, we call attention to the irony that consolidation was pursued with an explicit call for more equality in schooling in Dawson County (Swidler 2013) and yet population concentrations and variation in expenditures seemed …

A Simple Device For Measuring The Minimum Current Velocity To Maintain Semi-Buoyant Fish Eggs In Suspension, Julias S. Mueller, Brandon D. Cheek, Qingman Chen, Jillian Groeschel, Shannok K. Brewer, Timothy B. Grabowski

The Prairie Naturalist

Pelagic broadcast spawning cyprinids are common to Great Plains rivers and streams. This reproductive guild produces non-adhesive semi-buoyant eggs that require sufficient current velocity to remain in suspension during development. Although studies have shown that there may be a minimum velocity needed to keep the eggs in suspension, this velocity has not been estimated directly nor has the influence of physicochemical factors on egg buoyancy been determined. We developed a simple, inexpensive flow chamber that allowed for evaluation of minimum current velocity needed to keep semi-buoyant eggs in suspension at any time frame during egg development. The device described here …

Relationships Among Walleye Mercury, Selenium, Stable Isotopes, Size And Age, Mark J. Fincel, Robert P. Hanten, Shannon Minerich

The Prairie Naturalist

Bioaccumulation of mercury is well-documented in aquatic ecosystems and occurs as mercury is accumulated and passed up food chains (Kidd et al. 1995, Atwell et al. 1998, Downs et al. 1998). Trophic level correlations have been widely reported for mercury (Snodgrass et al. 2000) and other metals (Barron 1995). Generally, within a system, carnivores have the highest mercury loadings, omnivores intermediate and herbivores the lowest (Phillips et al. 1980). However, little research has focused on the differences in mercury bioaccumulation for a single species that ranges across multiple trophic levels (Burger et al. 2001).

Stable isotope analysis has expanded the …

Legislated Landscape: A Comparison Of New Deal Farm Communities In Hattiesburg, Mccomb, And Tupelo, Mississippi, Joy Delaine Rhoads

Master's Theses

Government New Deal farm policies of the 1930s changed the realities of farming and the landscape in Mississippi. This research endeavors to compare three farm communities created by New Deal legislation in the state: Hattiesburg, McComb, and Tupelo. The economic crisis that was the Great Depression created a highly politicized environment as citizens looked to the government for economic relief. A crisis this severe would require an exceptional effort to mitigate the economic hardships it created, in varying degrees, for millions of Americans. The actions of the federal government during the Great Depression were an interesting mix of paternalism, desperation, …

Loyalist Or Patriot: The Precarious Position Of Edmund Randolph, 1774-1786, Tanisha Jean Staten

Master's Theses

On May 29, 1787, Governor Edmund Randolph took the floor of the Constitutional Convention in Philadelphia with a radical plan for a new federal government. Randolph was a key member of the influential Virginia delegation which paved the way for United States' Constitutionalism. An examination of his early life, legal career, and politics offers a new lens with which to view the emergence of American constitutional ideology. Building off the work ofT.H. Breen, who argues that Virginia's landed gentry inhabited a distinct culture, this work illuminates the dynamics of these elites who were absolutely pivotal in shaping a new sense …

A Phenomenological Study Of The Factors Leading Low Socioeconomic Status Urban Students To Enroll In A University, Luke D. Schultheis

Department of Educational Administration: Dissertations, Theses, and Student Research

Low socioeconomic urban students do not attend universities at a rate proportional to other populations. This perpetuates a cycle of recurrence and diminished potential benefits associated with degree attainment. The commonly ascribed Theory of Student Choice (Hossler, Braxton & Coopersmith, 1989) does not apply to this population.

The purpose of this study was to identify factors which motivated low socioeconomic urban students to enroll in a university. Three interviews, each up to two hours, were conducted with students of this population. The participants identified why they chose to enroll in a university.

The participants were not motivated to attend a …

What Factors Impact The Effectiveness Of International Non Governmental Organizations (Ingos) In Ethiopia, Ermias Abraham

UNLV Theses, Dissertations, Professional Papers, and Capstones

Since the 1970s Ethiopia has experienced a massive increase of International Non-Governmental Organizations (INGOs) in its territory. The multiplication of these INGOs seems to be the result of the activities of both international donors and governments in Ethiopia. International donors considered INGOs as efficient, flexible or adoptive to the needs of the community and more trustworthy than government agencies in implementing development projects. International donors also believe that the proliferation of INGOs in Ethiopia will stimulate the growth of political democracy and trade liberalization. The government allowed the influx of these INGOs in order to tap the resources they bring …

Max Operation In Statistical Static Timing Analysis On The Non-Gaussian Variation Sources For Vlsi Circuits, Abu M. Baker

UNLV Theses, Dissertations, Professional Papers, and Capstones

As CMOS technology continues to scale down, process variation introduces significant uncertainty in power and performance to VLSI circuits and significantly affects their reliability. If this uncertainty is not properly handled, it may become the bottleneck of CMOS technology improvement. As a result, deterministic analysis is no longer conservative and may result in either overestimation or underestimation of the circuit delay. As we know that Static-Timing Analysis (STA) is a deterministic way of computing the delay imposed by the circuits design and layout. It is based on a predetermined set of possible events of process variations, also called corners of …

Object Detection Using Contrast Enhancement And Dynamic Noise Reduction, Justin Lee Baker

UNLV Theses, Dissertations, Professional Papers, and Capstones

Edge detection is one of the most important steps a computer must perform to gain understanding of an object in a digital image either from disk or from video feed. Edge detection allows for the computer to describe the shape of the objects in an image and create a pixel boundary defining what is considered part of an object, and what is not. Cannys edge detection algorithm is one of the most robust and accurate of these edge detection algorithms. However, as with many algorithms in image processing, there are many cases where the algorithm does not perform as well …

Developing Ethical Competence: The Perspective Of Nurse Educators From Pre-Licensure Baccalaureate Nursing Programs Accredited By The Commission On Collegiate Nursing Education, Jennifer Lee Bartlett

UNLV Theses, Dissertations, Professional Papers, and Capstones

Nurses face ethically-charged situations every day, yet ethics education is not universally integrated into pre-licensure baccalaureate nursing programs. Like other forms of competence, ethical competence requires development. Nurse educators are poised to impact on the competence of their students, both defining the ethics content and designing students' exposure. The purpose of this study is to describe the concept of ethical competence from the perspective of baccalaureate nursing faculty and describe current methods of integration and evaluation of ethics education in pre-licensure baccalaureate nursing programs. This research will be conducted using a sequential (quantitative-qualitative) mixed method approach. The first phase of …

Temperature Trends And Urban Heat Island Intensity Mapping Of The Las Vegas Valley, Adam Leland Black

UNLV Theses, Dissertations, Professional Papers, and Capstones

Modified urban climate regions that are warmer than rural areas at night are referred to as Urban Heat Islands or UHI. Islands of warmer air over a city can be 12 degrees Celsius greater than the surrounding cooler air. The exponential growth in Las Vegas for the last two decades provides an opportunity to detect gradual temperature changes influenced by an increasing presence of urban materials. This thesis compares ground based thermometric observations and satellite based remote sensing temperature observations to identify temperature trends and UHI areas caused by urban development.

Analysis of temperature trends between 2000 and 2010 at …

Actresses Redefining Theater And Femininity In Eighteenth-Century France, Rebecca Anne Bolen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Published in 1798 and 1800, the memoires of Hypolite Clairon and Marie-Françoise Marchand Dumesnil relate the experiences and values of individuals who lived through massive social and cultural, and eventually political, changes. How and when these two women felt the need to adhere to society's standards in comparison to those instances when they were confident enough to assert themselves illuminates the ways in which developing a public persona could open up a space for women to stretch the boundaries of feminine self-fashioning. This space was not unlimited and may have depended on actresses making concessions to societal expectations. It was …

The Lived Experiences Of Acute-Care Bedside Registered Nurses Caring For Patients And Their Families With Limited English Proficiency, Jami-Sue Coleman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Approximately 8.6% of the total U.S. population is considered limited English proficient (LEP), a term that has been used by official US federal policy and will be used throughout this study. In a landmark report, the Institute of Medicine found that minorities received lower-quality health care than Caucasians even when insurance status, income, and other factors were equivalent. These differences were tied to issues such as bias, stereotypes and communication barriers between patients and their caregivers. In the hospital setting, registered nurses provide the most direct contact with patients and their families. Effective communication between patients and health care professionals …
