The Effects Of The Jccs Curriculum On Juveniles' Legal Knowledge, Competency, And Anxiety, Leslie Strasser Murdock

UNLV Theses, Dissertations, Professional Papers, and Capstones

Current law requires that juveniles be competent to stand trial prior to their involvement as defendants in court. According to Dusky v. US, a defendant must have a rational and factual understanding of the court proceedings to be deemed competent to stand trial. Past studies call into question whether juveniles at any age could meet the understanding element of the standard articulated in Dusky v. US (1960). Additionally, youth with disabilities have less knowledge than their typical peers. Besides a lack of legal knowledge, court related anxiety has also been found to have a significant effect on youths going to …

Estimation Of Travel Time Based On Vehicle-Tracking Models, Anuj Nayyar

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this thesis we study the travel time problem based on the known traffic density model. Using the conservation law, we model the travel time function by a boundary value problem of a non homogeneous linear hyperbolic equation. The equation is transformed into an initial value hyperbolic equation, and the well-posedness of the problem is discussed. The mathematical analysis for both density and travel problems are given. We also derive the analytic solutions for several special cases of traffic density. Numerical schemes are proposed for solving for travel time problem. Several numerical examples are presented and error analysis on the …

Application Of Ntru Cryptographic Algorithm For Securing Scada Communication, Amritha Puliadi Premnath

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 …

Towards Operationalizing Complexity Leadership: How Generative, Administrative And Community-Building Leadership Practices Enact Organizational Outcomes, James K. Hazy, Mary Uhl-Bien

Department of Management: Faculty Publications

Over five years ago, The Leadership Quarterly published a special issue on complexity to advance a new way of thinking about leadership. In shifting attention away from the individual to the organizing process itself, complexity added an important focus on process and context to leadership and management research. Yet, the complexity approach creates challenges for researchers who must combine or replace individual level constructs—like those built through surveys or factor analysis—with richer theories that investigate networked meso dynamics, multilevel phenomena, emergent processes, and organizational outcomes. To address this challenge, the present analysis draws on theoretical and empirical work over the …

Exploring The Changing Effects Of Individual Differences On Social Status Of Influence, Wonho Jeung

College of Business: Dissertations, Theses, and Student Research

Social status and hierarchies of social status are ubiquitous. Because of this, they have been addressed in a great number of philosophical, theoretical, and empirical discussions across a variety of fields of studies. A primary focus of attention has been on the role of human agency, most notably trait theory (i.e., personality theory). Despite a number of studies in this topic, there have been two notable limitations in extant studies. First, previous studies have largely been based on a singular perspective in explaining social status, most representatively ability (e.g., intelligence) and personality traits (e.g., Big-Five personality traits). Second, extant studies …

Elements Of Traditional Folk Music And Serialism In The Piano Music Of Cornel Țăranu, Cristina Vlad

Glenn Korff School of Music: Dissertations, Theses, Student Creative Work, and Performances

The socio-political environment in the aftermath of World War II has greatly influenced Romanian music. During the Communist era, the government imposed regulations on musical composition dictating that music should be accessible to all members of society. Composers were therefore barred from writing works that were considered too complex or avant-garde for the standards of the nation. Many composers struggled with this official ideology because they wished to follow their own natural styles and desired to synchronize with Western compositional trends of the time, including aleatoric and twelve-tone serial music. Even before the government relaxed the restrictions on composition at …

Orchestral Tuba Audition Preparation: The Perspective Of Three Successful Teachers, Golden A. Lund

Glenn Korff School of Music: Dissertations, Theses, Student Creative Work, and Performances

Daniel Perantoni, Warren Deck, and Mike Roylance have played significant roles in developing students that have won orchestral tuba positions in recent decades. These three instructors are representative of the past 30 years in that the success of their students are tiered chronologically over that time period; Perantoni has had students winning orchestral positions since the 1980s, Warren Deck’s studio began flourishing in the 1990’s, and Mike Roylance’s students have been emerging since he began teaching in Boston in 2003.

The purpose of this study was to determine commonalities and differences between the three of these teachers. Their effectiveness was …

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 …

Assessments Of Student-Teacher Relationships In Residential Treatment Center Schools, Kathleen Moritz Rudasill, Amy B. Gonshak, Patrick Pössel, Andrew Nichols, Natalie Stipanovic

Department of Educational Psychology: Faculty Publications

Students in residential treatment center (RTC) schools are likely to have histories of extreme or ongoing relational trauma (e.g., abuse and neglect by primary caregivers), have substantial interpersonal and relationship problems, and exhibit many high-risk behaviors. Accordingly, these students may have particular difficulty forming positive relationships with teachers, yet student-teacher relationship quality in RTC schools has not been empirically studied. This study examines links between RTC school students’ assessments of their relationships with teachers and their perceptions of self and others. Participants were 113 students in 2 RTC schools from 5th to 12th grade. Results indicate that male and female …

Direct Observations Of Plasma Upflows And Condensation In A Catastrophically Cooling Solar Transition Region Loop, Norton B. Orange, David L. Chesney, Hakeem M. Oluseyi, Katie Hesterly, M Patel, Patrick Champey

Aerospace, Physics, and Space Science Faculty Publications

Minimal observational evidence exists for fast transition region (TR) upflows in the presence of cool loops. Observations of such occurrences challenge notions of standard solar atmospheric heating models as well as their description of bright TR emission. Using the EUV Imaging Spectrometer on boardHinode, we observe fast upflows (vλ −10 km s−1) over multiple TR temperatures (5.8 logT 6.0) at the footpoint sites of a cool loop (logT 6.0). Prior to cool loop energizing, asymmetric flows of + 5 km s−1 and −60 km s−1 are observed at footpoint sites. These flows, speeds, and patterns occur simultaneously with both magnetic …

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 beer industry has seen rapid growth expansion in the U.S. In 1980, there were roughly 100 breweries in the nation and today there are over 2500 (Brewers Association, 2013a). With the rapid …

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 …

Robust And Adaptive Attitude Control Of Spacecraft Using Solar Radiation Pressure, Lakshmi Srinivasan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Satellites in orbit are expected to maintain a preset attitude either pointing towards Earth (in case of satellites for weather) or pointing towards space for the purpose of research and exploration. The satellite as a system though is extremely nonlinear and the system parameters are not easily available. The goal of this thesis is to develop robust and adaptive control laws that can be used to control the attitude of satellites in elliptic orbits. The attitude of the satellite is controlled by the use of Solar Radiation Pressure (SRP) on the solar panels of the satellite. The SRP is basically …

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 …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Construction and professional disadvantaged, minority, and women business enterprises (DBE/MBE/WBEs) face several impediments that hinder their business growth. A questionnaire survey was conducted to determine the important factors that affect their business performance, impediments faced by these business enterprises, advantages, and disadvantages of being DBE (DBE will be an umbrella designation for DBE, MBE, and WBE). This study compares the difference in responses from these two groups. A total of 333 business enterprises responded to the questionnaire. The survey results showed that construction firms gave significantly higher importance to "financial" issues and "safe work practices" as their most important factors …

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 …

Resemblance-Oriented Communication Strategies: Understanding The Role Of Resemblance In Signed And Spoken Languages, Daniel R. Eberle

Theses and Dissertations

The goal of this thesis is to propose that resemblance plays an important role in human communication. Saussure proposed a characteristic principle of the linguistic sign: that connections between linguistic codes and the objects they signify are arbitrary; however, I intend to show that resemblance, which I define as the visual or aural similarity between a stimulus, the thought it is intended to activate, and the real world target that utterance is about, is an important part of human communication and should be taken into consideration when defining language and proposing theories of human communication.

I have chosen Relevance Theory …

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 …

Chipless Rfid Tags Based On Multiple Band-Rejected Planar Log-Periodic Antennas, Shulabh Gupta, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

A passive chipless Radio-frequency identification (RFID) tag is proposed based on the tailorable band-rejection property of the log-periodic (LP) antennas. The proposed tag principle is successfully demonstrated using full-wave simulations, where the absence and presence of the band-rejection in VSWR and thus radiation gain, is shown to carry the bit information. Due to the large number of dipole radiators on the LP aperture, the proposed tag can easily support large number of codes, providing a potential solution for limited number of bits in conventional chipless tags. © 2013 IEEE.

Co-Simulation Of Distributive And Lumped Systems Using The Discontinuous Galerkin Time Domain Finite Element Method, Ping Li, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

The signal integrity and power integrity analysis of 3D integrated circuits or other EMC/EMI systems usually separate the lumped circuit modeling and the distributive system modeling. However, due to the high density of integration, it is not proper to separate them in the modeling process anymore. In this paper, a hybrid electromagnetics (EM)-circuit simulator is proposed for incorporating multiport lumped circuit networks through their admittance matrices into the discontinuous Galerkin time-domain finite element method (DGTDFEM). The admittance matrix in the Laplace-domain can be derived analytically or obtained from network parameters such as S-parameters in the frequency domain. To convert frequency …
