Environmental Influence On Brain, Behavior, And Gene Expression In Drosophila, Xia Wang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Brain development and behavior are sensitive to environmental stimuli. To gain an understanding of how and to what extent environmental variations, particularly with regard to thermal stress and sensory input, affect brain development, function, and genomic activity, in this dissertation, three interrelated studies were conducted in Drosophila melanogaster.

The first study examined the effects of ecologically-relevant hyperthermia stress on development of the Drosophila mushroom body (MB), a conserved sensory integration and associative center in the insect brain. A daily hyperthermic episode throughout larval and pupal development was shown to severely disrupt MB anatomy by reducing intrinsic Kenyon cell neuron …

Hotel Revenue Management: Investigating The Interaction Of Information Technology And Judgmental Forecasting, I-Pei Claire Chen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Traditionally, forecasting has included human judgment and/ or guessing. The process has often been described as “guesstimation.” For instance, people are easily affected by user interface issue or rewarding policies during this process. The purpose of the study is to study and understand how revenue managers and other decision makers “make noise” during forecasting, especially when utilizing the advanced RMS, and to offer constructive suggestions to overcome the issues related to human judgment. In other words, the main objective of this study is to analyze the known influential factors for the interaction of revenue managers’ judgment and RMS tools by …

Learning With Animation And The Illusion Of Understanding, Eugene Sam Paik

UNLV Theses, Dissertations, Professional Papers, and Capstones

A controlled experiment was conducted on the effects of two types of animation - motion and highlighting - on learning. The treatment consisted of a 3.5 minute multimedia presentation that described the workings of a flushing toilet tank. A 2x2 factorial design ({motion, no-motion} x {highlight, no-highlight}) was employed with two dependent measures of learning (retention and transfer). Participants consisted of 65 undergraduates. Highlighting animation had a positive effect on both retention and transfer while motion animation had a negative effect on transfer. No significant interaction was detected between motion and highlighting.

In addition, the experiment tested the illusion of …

Can Self Service Technologies Work In The Hotel Industry In Singapore? A Conceptual Framework For Adopting Self Service Technology, Lixin Iris Ong

UNLV Theses, Dissertations, Professional Papers, and Capstones

The proliferation of self service technologies has changed the way customers interact with service employees and technology. More consumers are now valuing the convenience, consistency, and the control they have over the self service technologies. However, despite the growing popularity of these technologies, hotel industries in Singapore have not embraced self service technologies in their day to day operations. Self service technologies present opportunities for hotels to improve on service standards, and the wide variety of technology applications available allow hotels to choose an application that suits the customers and the hotels needs. To enable hotels to seamlessly adopt self …

Efficiency Of Fiscal Allocations In Site-Based Empowered Schools, Jerome Jay Meyer

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study implemented a two phase concurrent mixed-methods design to generate a greater understanding of how elementary schools with increased autonomy in fiscal decision making allocated their money, how their site-based decisions affected allocative efficiency, and how increased autonomy affected site-based decision making when compared with a set of matched control schools within a large urban district.

Phase I compared school site expenditure patterns of site-based empowered schools to demographically matched control schools and to all elementary schools within a large urban district over four years, 2004-05, 2005-06, 2006-07, and 2007-08. Expenditure data were collected from the In$ite data base …

The Physical Activity Patterns And Constraints Of Diverse Female College Students, Kathleen Victoria Minkel

UNLV Theses, Dissertations, Professional Papers, and Capstones

Diverse college aged females from a public university in the southwest were asked to participate in an online survey to determine their constraints to physical activity, as well as their current activity level. The groups were compared to establish the differences among the minority groups. Raymore, Crawford, and Godbey’s Hierarchical Model of Constraints was used as a framework when creating the survey. Data analysis showed only one significant difference among the racial/ethnic groups, when looking specifically at the intrapersonal, interpersonal, and structural constraints categories. Hispanic women differed significantly from Caucasian women in their perception of interpersonal constraints on their physical …

Evaluation Of Guided Visualizations And The Relationships Among Perceived Stress, Differentiation Of Self, Sense Of Coherence, Dyadic Satisfaction And Quality Of Life, Kim R. Rogers

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study focused on three main areas. These areas involved (1) the relationship among perceived stress, global orientation to life and indicators of physical, psychological and dyadic relational distress, (2) the effect of a brief CBT-based relaxation/guided visualization intervention on these outcome indicators of distress, and (3) changes in physiological indicators during the intervention sessions. The study population was drawn from couples who perceived themselves as living highly stressed lifestyles.

Results suggested that global orientation to life as reflected by differentiation of self inventory (DSI) and sense of coherence scale (SOCS) scale scores mediated the relationship between stress and distress. …

Evaluating And Improving The Quality Of Teacher’S Language Modeling In Early Childhood Classrooms, Lillian White Englund

UNLV Theses, Dissertations, Professional Papers, and Capstones

The relationship between pre-school teachers and the children in their classrooms directly influences the degree of success the children experience in school and in life. The emphasis on quality pre-K education in the U.S. has resulted in an increased need for highly qualified teachers who are capable of engaging in meaningful interactions with young children. An important component of high-level teacher-child interactions is the teacher's ability to model language for children as they acquire vocabulary and language context.

This mixed-methods study was designed to examine the effectiveness of a professional development intervention designed to improve the quality of language modeling …

Counseling Professionals' Attitudes Toward Transgender People And Responses To Transgender Clients, Emily A. Nisley

Dissertations

The multicultural counseling movement emphasizes the critical nature of counselor attitudes in providing culturally competent service (e.g., Sue, 2001; Sue, Arredondo, & McDavis, 1992; Sue et al, 1982; Sue & Sue, 2003). Until recently, however, the counseling professions have paid little attention toward transgender people as a cultural minority group. The purpose of this study was to conduct the first assessment of counseling professionals' attitudes toward transgender people and to examine relationships between such attitudes and responses to a transgender client.

A national convenience sample of 138 master's and doctoral level counselors and counseling psychologists, recruited via electronic mailing lists, …

Effects Of Yellow Rectangular Rapid-Flashing Beacons And Novel Lane Markings On Motorists’ Yielding, Speed, And Headway At Multilane Uncontrolled Crosswalks, Jimmy Wayne Shurbutt

Dissertations

Several methods have been examined to increase motorists’ yielding to pedestrians and the distance at which they yield on multilane crosswalks at uncontrolled locations with relatively high average daily traffic (ADT). A series of 5 experiments were conducted to evaluate the efficacy of rectangular rapid-flashing beacons (RRFBs) as effective pedestrian crossing aides. The first experiment found that the RRFBs produced a significant increase in yielding behavior at all 26 sites located in 3 cities in the United States. Data collected over a 2-year follow-up period at 22 of these sites plus 14-month follow-up at an additional 4 sites documented the …

Dissertations, Theses and Capstone Projects (Full IR Collection)

This paper investigates how the application of bibliotherapeutic intervention affects teachers’ perceptions of bullying in their young students, ages four and five. Bullying has become a serious global concern that has manifested itself in school dropouts, shootings, and suicides. Bibliotherapy is one way to help children solve problems using books and is advocated by researchers for use with bullying prevention.

Little research has been done on bullying in young children. This qualitative phenomenological study will add to the body of literature regarding bullying in young children ages four and five and will examine perceptions of teachers of young children regarding …

Quilts As Visual Texts, Marcia Inzer Bost

Dissertations, Theses and Capstone Projects (Full IR Collection)

I argue that quilts should be considered as visual texts, one to which theories of visual rhetoric and rhetoric in general can be applied. In drawing together the worlds of academia and quilting, I will use a variety of theoretical lens to explore quilts as texts. As a text, quilts contain units of meaning much like words. These units of meaning will be explored in Chapter 2 “Quilt Talks: How Quilts Communicate.” In this chapter I will follow the model of Elsley and propose a semiotics of quilts, one that can then be applied to any quilt. This semiotics is …

The Fertile Dark, Jacob M. Martin

Dissertations, Theses and Capstone Projects (Full IR Collection)

The Fertile Dark is a portfolio comprised of approximately forty poems and an introductory essay. All of the poems were written and revised by me while I was a student in the Master of Arts in Professional Writing program, working under the direction of Dr. Jim Elledge and Dr. Ralph Wilson. Although no single theme characterizes the portfolio, the interplay between darkness and light may be seen throughout. As the son of a minister, I am fascinated by these elemental forces and how they shape our lives, our realities, and our beliefs.

At-Will Employment In The Public Sector: A Case Study Of The Georgia Reform, Olayinka Tejuoso

Dissertations, Theses and Capstone Projects (Full IR Collection)

Prior to the advent of at-will employment, elected officials and public managers have laid blame on government in the United States of being distended, unproductive, and impassive. The Civil Service Reform Act of 1978 abolished the Civil Service Commission and endorsed reformation of workforce practice and policies. Many states in the United States have followed suit, but with limited measures (Battaglio 2010). It is apparent, nonetheless, that a lot of political executives and professional managers have lingered on in aggravation, and are pushing for more considerable influence and stiffness over employees. As a consequence of at-will employment over the years, …

Political And Civic Engagement Attitudes Among Asian American College Students, Matthew Vanada

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study explored the attitudes of political and civic engagement among Asian American college students. Previous research suggests that young people are increasingly more inclined to participate in civic activities over traditional forms of political participation. The researcher considered this trend by examining the views of Asian American students, a group whose political behavior has not been largely investigated.

This study employed a qualitative research design. Students from public institutions of higher education in Las Vegas were interviewed using an in-depth and semi-structured format. Findings suggest that there is a general willingness to become involved in civic activity such as …

Violence, Symbols, And The Archaeological Record: A Case Study Of Cahokia's Mound 72, Kathryn Koziol

Graduate Theses and Dissertations

Acts of violence are not always easily distinguished in their form. Given the additional difficulties caused by the obscure nature of the archaeological record, it is no wonder that interpretations of these behaviors are so skewed both between and within fields of research. There is little consistency in this academic dialogue, which prevents researchers from grappling with the larger perspectives that should be approached. For instance, just how far back in our human history have events such as genocide occurred? Are these modern in origin? The scale of ancient events and our anthropological scopes need more adjustment to the unique …

The Secret Identity Of Race: Exploring Ethnic And Racial Portrayals In Superhero Comic Books, Lowery Anderson Woodall Iii

Dissertations

Does race exist in comics? And if so, what do those characters tell us about how one of the largest fiction producing industries in the country has explained minority relationships to its millions of readers? This study took a close look at three of the most successful comic book characters of all time (Batman, Superman, and The Black Panther) and examines how each exemplifies a position that the comic book industry has taken on race over the years. Using a counter-narrative analysis informed by the strategies of Critical Race Theory and post-modernist thought, the racial messages lying beneath the surface …

Examining Relationship Interactions Of Adult Children Of Alcoholics, Diana I. Loera

Master's Theses

The following study explores the factors associated with security of romantic attachment in Adult Children of Alcoholics (ACOAs). ACOAs are more vulnerable to inconsistent parenting and consequently are more likely to develop negative internal models of self, a stable construct that affects romantic attachments (Bowlby, 1982; Ainsworth et al, 1989; Bartholomew, 1990). This study examined associations between parent, and peer relationships as possible resiliencies. It was hypothesized that ACOAs will report less secure attachments with their parents (as measured by the IPPA), less romantic attachment anxiety and avoidance (as measured by the ECR-R), and no significant difference in peer attachment …
