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 …

Tier 3 Intervention: Youth Courts, Ann O'Connor, Emily Moss, Jenna Strawhun, Reece L. Peterson

Department of Special Education and Communication Disorders: Faculty Publications

Conclusion

Youth courts represent a promising approach to developing youth involvement in diminishing juvenile delinquency and substance abuse, and as such, represent a useful approach to crime and violence prevention. As with conflict resolution education and peer mediation programs, the potential benefit of youth courts is two-fold. First, it has the possibility of diminishing youth crime and recidivism directly through the sanctions imposed and restorative practices used. Secondly, it may affect a wider group of teens through the skills, training and experiences of the youth volunteers. Based on the evaluation data to date, the youth court program appears to be …

Magnetic Anisotropy And Exchange In (001) Textured Fept-Based Nanostructures, Tom George

Department of Physics and Astronomy: Dissertations, Theses, and Student Research

Hard-magnetic L1₀ phase FePt has been demonstrated as a promising candidate for future nanomagnetic applications, especially magnetic recording at areal densities approaching 10 Tb/in². Realization of FePt’s potential in recording media requires control of grain size and intergranular exchange interactions in films with high degrees of L1₀ order and (001) crystalline texture, including high perpendicular magnetic anisotropy. Furthermore, a write-assist mechanism must be employed to overcome the high coercivity of L1₀ FePt nanograins. The research described in this dissertation examines potential solutions to the aforementioned problems. Specifically, a nonepitaxial method of fabricating highly (001) textured …

A Study On Countermeasures Against Steganography: An Active Warden Approach, Qilin Qi

Department of Computer Electronics and Engineering: Dissertations, Theses, and Student Research

Digital steganography is a method used for hiding information in digital images. It can be used for secure communication. There have been many robust digital steganography methods invented in recent decades. The steganographic message can be inserted in multimedia cover signal such as audio, image and video. However, this technique also may be used by malicious users to transmit dangerous information through the Internet beyond the control of security agencies. How to detect and/or block potentially dangerous information transmission on the Internet through billions of multimedia files while not affecting innocent multimedia communications becomes a challenging problem. Existing steganalysis methods …

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 …

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 …

An analysis of the dynamic behavior of the shockwave in this reactor is the subject of this thesis. As a shockwave travels through a fluid medium, the characteristics of …

The Ethics Glass Ceiling: A Historical Analysis Of Actions By The U.S. House Of Representatives Committee On Ethics, Michael James Gordon

UNLV Theses, Dissertations, Professional Papers, and Capstones

The breaking of moral and ethical codes has been with humankind since history was first recorded. As such, the public wants to know that their elected officials are held accountable and cannot disregard enshrined legal rights without incurring broader personal and societal consequences. Within the hallowed halls of government, the "unrequested" House Committee on Ethics (HCE) provides the forum of accountability.

In this qualitative, historical case study, HCE documents are analyzed and both the internal and external motivating factors behind the actions of the HCE members are examined. Computer assisted qualitative data analysis software, namely ATLAS.ti, was used to look …

What Works In Suicide Bereavement: What Helps And What Hurts?, Quintin Hunt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Suicide is one of the most painful grief experiences that any family may experience. The suicide bereavement literature, though small, is replete with research that shows family and systemic impacts of suicide. The literature also includes constant calls for family- and systemic-based intervention as every part of society is impacted. Research in the field of marriage and family therapy, however, has ignored suicide and suicide bereavement almost entirely. The purpose of this qualitative study is to develop a more thorough understand of the grief that survivors of suicide experience and to systemically understand what helps and hurts the grieving process. …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Supervisory Control and Data Acquisition (SCADA) system is a control system which is widely used in Critical Infrastructure System to monitor and control industrial processes autonomously. Most of the SCADA communication protocols are vulnerable to various types of cyber-related attacks. The currently used security standards for SCADA communication specify the use of asymmetric cryptographic algorithms like RSA or ECC for securing SCADA communications. There are certain performance issues with cryptographic solutions of these specifications when applied to SCADA system with real-time constraints and hardware limitations. To overcome this issue, in this thesis we propose the use of a faster and …

Cell Phones, Police Recording, And The Intersection Of The First And Fourth Amendments, Conor M. Reardon

Duke Law Journal

In a recent spate of highly publicized incidents, citizens have used cell phones equipped with video cameras to record violent arrests. Oftentimes they post their recordings on the Internet for public examination. As the courts have recognized, this behavior lies close to the heart of the First Amendment.

But the Constitution imperfectly protects this new form of government monitoring. Fourth Amendment doctrine generally permits the warrantless seizure of cell phones used to record violent arrests, on the theory that the recording contains evidence of a crime. The Fourth Amendment inquiry does not evaluate a seizing officer's state of mind, permitting …

Getting Slapp-Ed In Federal Court: Applying State Anti-Slapp Special Motions To Dismiss In Federal Court After Shady Grove, Katelyn E. Saner

Duke Law Journal

In recent years, dozens of states have enacted anti-Strategic Lawsuits Against Public Participation (SLAPP) laws to counter SLAPP suits, or lawsuits filed to silence a defendant who has spoken out against a plaintiff. The goal of a SLAPP suit is not to win on the merits, but rather to discourage the defendant's right to free speech through the prospect of ruinously expensive litigation. State anti-SLAPP laws provide for special motions to dismiss, which allow a defendant to file an expedited motion to dispose of the SLAPP suit before engaging in costly discovery.

It is well established that a federal court …

Bureaus And Beer: Promoting Brewery Tourism In Colorado, Shane Howlett

UNLV Theses, Dissertations, Professional Papers, and Capstones

Beer, wine and spirits are three little words that make lots of people excited. Alcohol can be thought of as a necessity for tourists. In recent years, consumers are becoming more interested in the development and processes behind their favorite libations. This has spurred a new type of tourist; those that are interested in brewery tours, vineyard hopping, or enjoying a day out at their favorite distillery.

The Perceived Level Of Enjoyment In Sports Violence: An Experiment Examining How Sports Commentary, Fanship, And Gender Affect Viewer Emotions, Sarah Vineyard

UNLV Theses, Dissertations, Professional Papers, and Capstones

This investigation examines if the independent variables of sports commentary, fanship, and gender affect the viewer's level of perceived enjoyment while watching sports violence through televised professional football and hockey clips. Previous studies have found that these three variables contribute most to a viewer's level of perceived enjoyment. This study aimed to test to see if that was still true, while taking into account new rules regarding violence by the National Football League and the National Hockey League. This thesis addresses all variables in one study, which something past research has failed to do.

Perhaps the most significant finding from …

Media Bias Through Facial Expressions On Local Las Vegas Television News Programs: A Visual Content Analysis, Jessica Zimmerman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Trust in news media has been considered an important base for social order and cohesion in society and is a crucial variable for evaluating news media. Media credibility has been questioned by the audience for some time and the audience's trust in the media has been slowly diminishing over the years. When a news broadcaster communicates a story on local television news, it is possible for his own opinions to leak through nonverbal communication, specifically facial expressions. This thesis explores the six local Las Vegas television news stations' anchors and reporters to visually analyze whether facial characteristics reveal media bias …

The Hotel Manager’S Perceived Conflict Of Providing For Hospitality And Security: Can The Two Exist In Harmony?, Silvano Cozzini

UNLV Theses, Dissertations, Professional Papers, and Capstones

The hospitality industry relies upon regular and repeat customers for its survival. No traveler or visitor will return to a hotel property where a bad incident occurred. Would a diner go back to any restaurant where they were sickened by their meal? Would a hotel guest return to any property where they were a victim of a crime? Bad experiences make us tell ourselves, “I will never go back there again!”

This same psychology holds true for criminals. At places where they have been deterred by a high security presence, it is unlikely that they would return there, either. A …

What Do They Do In Las Vegas Strip Casinos? An Analysis Of The Attitudes And Behaviors Of Gen Y Casino Customers, Mei Iok Un

UNLV Theses, Dissertations, Professional Papers, and Capstones

Totaling over 63 million, Generation Y, also known as the Millennial Generation, is the new generation of casino customers (U.S. Department of Commerce, 2011). While there are no specific dates to mark its beginning and ending, individuals born between 1982 and 1994 are generally considered as Millennials or Gen Yers. A survey conducted by the American Gaming Association (2013) revealed that Gen Y casino customers made up the highest casino visitation rate with 39% having visited a casino in the previous year; however, it is also shown that Gen Yers spends more on non-gaming departments and have less intention to …

The Tweet Delete Of Congress: Congress And Deleted Posts On Twitter, Theresa Loraine Cardenas

Master's Theses

Since 2006, increasingly more politicians have joined , and are active on, social media networks, in order to reach out to constituents. However, politicians, such as Anthony Weiner, have started to find themselves in the middle of Twitter scandals and criticism, since their posts are openly available to the public. These ramifications may be leading politicians to delete their tweets, but thanks to the Sunlight Foundation and its website Politwoops, deleted tweets by politicians are now archived and ripe for political research. This raises the question Which members of Congress are deleting tweets and why? Thus, I conduct the first …

Many Voices, Many Selves: An Analysis Of Education Blog Discourses, Kelli Lynn Finney

Theses and Dissertations

At this point, the majority of computer mediated communication (CMC) studies have employed a variation analysis approach, quantitatively describing language on the Internet and comparing CMC to speech and writing. While these studies have provided valuable information about CMC, they have also left many gaps, especially related to social and ideological issues such as language use.

This study responds to the need for more qualitative studies of language on the Internet by examining one form of CMC: education blogs. The study analyzes a selection of posts from five blogs published between March 21, 2012 and March 28, 2013. These five …

Capacitance Calculation For Via Structures Using An Integral Equation Method Based On Partial Capacitance, Hanfeng Wang, Siming Pan, Jingook Kim, Albert E. Ruehli, Jun Fan

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a new integral equation formulation for via structures is developed for the capacitance extraction between vias and planes. The formulation is initially developed for axially symmetric geometries and then extended to axially asymmetric geometries by changing the circular ring cells to arc cells. The extended method can be used to calculate the shared-antipad via structure, which is widely used in high-speed differential signal interconnects. In addition, the image theory is used to handle inhomogeneous media, and a new technique is given to reduce computational costs for via-to-plane structures based on properties of the capacitance-matrix elements. The proposed …

Predictors Of Hiv Risk Behaviors Among Older Adults : A Multilevel Analysis., Laneshia Rae' Mccord

Electronic Theses and Dissertations

Over the past thirty years, HIV has become a worldwide epidemic. Given the surge in the rate of sexually transmitted diseases including HIV, this sheds light as a new worry for sexually active older adults, raising questions about risk behaviors among this group. The issues facing older adults are three-fold in that they are 1) not identifying themselves as being at risk; 2) not identifying risk behaviors; and 3) are not largely being identified in the public realm as participating in risk behaviors. For these reasons, understanding both environmental and individual factors and their unique influences on HIV risk behaviors …

Xbp1 And Mist1 Are Not Sufficient To Induce The Regulated Secretory Pathway In Parotid Cell Lines., Ian S. Pyle 1986-

Electronic Theses and Dissertations

BACKGROUND: Xerostomia causes oral infections, tooth decay, and hindered digestion. Crucial to oral homeostasis is the salivary proteome. How these proteins are trafficked through secretory cells into secretory pathways is unknown. Abundant in the saliva is Parotid Secretory Protein (PSP), secreted through the regulated secretory pathway. HYPOTHESIS: The addition of XBP-1 and Mist1, known for differentiation marker regulation, to ParC10 cells will improve stimulated secretion of PSP. METHODS: Fusion clones were transiently or stably transfected into ParC10 cells. Media from non-stimulated and stimulated cells was harvested and luciferase activity was assayed. RESULTS: Stimulated secretion of cypridina-PSP was not significantly higher …
