The Gritty Black Single Mother: Protective Factors And The Influence Of Black Single Mother’S Grit On Young Adult Outcomes, Keara Cherrell Washington

Theses and Dissertations

Over the span of decades, literature has highlighted that offspring from Black Single Maternal Caregiver Households (BSMCH) will experience negative outcomes, including academic deficits and psychological distress, as a function of the adversarial barriers (i.e. low socioeconomic status, mother’s lack of educational attainment, and ecological threats) encountered within their environment. Despite the apparent potential negative outcomes, there are numerous examples of Black offspring from BSMCH who are resilient and successful, despite dire familial circumstances. However, their stories do not appear to be reflected in the literature. The purpose of this study was to reveal the untold story of resilient Black …

Mining Location And User Information From Users’ Trajectories, Marcello Tomasini

Theses and Dissertations

The understanding of human mobility is integral to the advancement of many fields including public health, city planning, economic forecasting, and it attracts the interest of researchers from a broad number of fields. The work of such researchers would not have been possible without the availability of large localized datasets such as mobile phone Call Detail Records (CDRs) provided by telco operators and Location Based Social Networks (LBSNs) check-ins provided by popular applications such as Twitter, Facebook and Foursquare. However, such datasets are often incomplete, anonymized, and/or inaccurate. Hence there is a need to partially reconstruct or extract more information …

The Role Of Entitlement, Self-Control, And Risk Behaviors On Dating Violence Perpetration, Kimberly A. Tyler, Rachel M. Schmitz, Colleen M. Ray, Leslie Gordon Simons

Department of Sociology: Faculty Publications

Dating violence continues to be pervasive among college students (Stappenbeck & Fromme, 2010). Given the paucity of research investigating the various pathways through which risk factors are linked to dating violence among different college campuses, we use multiple group path analysis to examine the role of child abuse, self-control, entitlement, and risky behaviors on dating violence perpetration among college students from one Southeastern and one Midwestern university. There were 1,482 college students (51% female) enrolled in undergraduate courses at 2 large public universities who completed paper and pencil surveys. Dating violence perpetration was directly associated with gender, child physical abuse, …

The Effects Of Real-Time Visual Performance Feedback Using A Tier Approach For Increasing Behavior Specific Praise On Teachers, Elizabeth Lown

Master's Theses

A number of studies have found behavior specific praise to be effective in increasing academically engaged behaviors and decreasing disruptive behaviors of students. The proposed study evaluated the effects of real-time visual performance feedback as a strategy for promoting teacher use of behavior-specific praise. An ABCBC design was utilized to determine the efficacy of real-time visual performance feedback in comparison to delayed visual performance feedback. The primary dependent variable measured was teacher use of behavior-specific praise. Additionally, student outcomes were assessed to determine the relationship between teacher use of behavior-specific praise and student behavior. The results from the study provide …

Factors Associated To Teacher Longevity In A Title I Elementary School: A Qualitative Narrative Inquiry Study, Richard Devney

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

The potential of our nation is hinged upon the strength of our educational system across all 50 states. Public education is the backbone of our country and continues to be a spotlight of focus for many. In 1983, President Ronald Regan shared the “Nation at Risk” report, based on the findings from the National Commission on Excellence in Education. The report claimed a level of mediocrity permeated the public education system and children were lagging behind compared to children in other first world countries. This landmark report put a level of accountability on school officials to create higher performing students …

Anomalydetection: Implementation Of Augmented Network Log Anomaly Detection Procedures, Robert J. Gutierrez, Bradley C. Boehmke, Air Force Institute Of Technology, Cade M. Saie, Trevor J. Bihl

The R Journal

As the number of cyber-attacks continues to grow on a daily basis, so does the delay in threat detection. For instance, in 2015, the Office of Personnel Management discovered that approximately 21.5 million individual records of Federal employees and contractors had been stolen. On average, the time between an attack and its discovery is more than 200 days. In the case of the OPM breach, the attack had been going on for almost a year. Currently, cyber analysts inspect numerous potential incidents on a daily basis, but have neither the time nor the resources available to perform such a task. …

Furniture For Quantitative Scientists, Tyson S. Barrett, Emily Brignone

The R Journal

A basic understanding of the distributions of study variables and the relationships among them is essential to inform statistical modeling. This understanding is achieved through the computation of summary statistics and exploratory data analysis. Unfortunately, this step tends to be under-emphasized in the research process, in part because of the often tedious nature of thorough exploratory data analysis. The table1() function in the furniture package streamlines much of the exploratory data analysis process, making the computation and communication of summary statistics simple and beautiful while offering significant time-savings to the researcher

Department of Management: Faculty Publications

I will be making some highly personalized comments on the Aguinis et al. article* concerning rigor vs. relevance, renaming/rebranding I-O psychology, and I-O psychology vs. business school OB. Before commenting, however, I feel compelled to briefly frame my remarks from the perspective of my 50-year academic career. For example, I think it is important to note that I go back to the early 1960s at the University of Iowa, College of Business. I was studying for my Ph.D. in the just emerging field of management and organizations (nothing was offered called organizational behavior or strategic management). However, and very unusual …

Remember The Country And The Age In Which We Live": The British Gothic Novel In The Age Of Enlightenment, 1764-1798, Garland David Beasley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Remember the Country and the Age in Which We Live” argues that the British Gothic novels produced in the late eighteenth century were not, as has traditionally been assumed, written in reaction against Enlightenment values in the face of rising political and social discord. Instead, I contend that eighteenth-century Gothic novels take part in a larger tradition of the novel that sought to impart the values of Enlightenment into a modernist genre still on the rise. By exploring the influence of Samuel Richardson on the development of the Gothic novel, the role of formal and informal educational structures, representations of …

Validity And Diagnostic Accuracy Of Broad Symptom Measures And Adhd Symptom Ratings For Identifying Individuals With Adhd Combined And Adhd Inattentive, Stacy Jean Graves

UNLV Theses, Dissertations, Professional Papers, and Capstones

Neuropsychological assessments conducted with children with Attention Deficit Hyperactivity Disorder (ADHD) often includes broad measures of behavioral disturbances, as well as specific measures of ADHD symptomatology. However, it is unclear the extent to which these two types of measures share substantial common variance or are useful in improving diagnostic accuracy. In efforts to increase efficiency, the current study examined these matters to provide clinicians with information that might help improve the selection of behavioral ratings for evaluation purposes.

Participants included in this study were evaluated for clinical purposes at a community based private practice. Participants included 253 of these children …

Student Expectations And Motivation In Spanish For Heritage Speakers Programs, Sergio A. Guzman

UNLV Theses, Dissertations, Professional Papers, and Capstones

The changing demographics in the United States and the growing need for multilingual individuals originated by globalization, among other reasons, have contributed to the emergence of a new field within the area of Applied Linguistics: The Teaching and Learning of Heritage Languages. Due to historical and geographic causes, Spanish for Heritage Speakers (SHS) is currently the largest and most established of these programs. However, the curricula, like those of most college courses, has been developed from professors’ perspectives, largely ignoring what students want to learn and/or their motives for enrolling in these classes. The lack of student input is especially …

The Design And Validation Of A Rhythm Span Task, Elizabeth Hofschulte Collins

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to design and validate a rhythm span task. Existing rhythm span tasks do not address important elements of rhythm and music such as tempo (speed), length (duration in beats per minute), and complexity (level of syncopation). This rhythm span task includes every combination of these criteria. The rhythmic sequences were presented with a piano sound from computer audio speakers. To align with traditional simple span tasks, the rhythm span task required participants to reproduce the rhythmic sequence. Results from this study showed that length was a significant factor for difficulty. Short rhythms were found …

Client’S Perception Of Therapist’S Way-Of-Being, Derek Holyoak

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this research is to investigate how clients’ perception of their therapist’s way of being impacts client engagement during the therapeutic process. By utilizing a common factors perspective, which emphasizes the importance of a strong therapeutic alliance between clients and therapists, the researcher aims to provide empirical evidence supporting the Therapeutic Pyramid Meta-Model. The Meta-Model, which was created by Fife and colleagues (2014), lays the foundation of effective psychotherapy as a therapist’s way-of-being. The meta-model is concurrent with the common factors literature which accounts for almost 30 percent of therapeutic change to therapist-relationship factors. A phenomenological framework, in …

Sexual Desire Trajectories: Heterosexual Individuals' Perceptions Of The State And Trait Characteristics Of Desire, Caroline Maykut

UNLV Theses, Dissertations, Professional Papers, and Capstones

Significant theoretical and empirical attention has aimed to classify sexual desire in a way that accounts for its complexities. A recent question to arise from this discussion is whether desire is best conceptualized as a state or a trait. Limited data examine patterns of desire spanning several years, and most data emanate from cross-sectional or short-term follow-up studies. Long-term accounts of desire level variability remain a gap in the literature, as does research inquiring directly about the question of trait desire.

Thirteen heterosexual women and ten heterosexual men, ages 40-63, participated in a semi-structured interview focusing on desire level and …

Subjective Beat Perception In Musical Rhythms In Adult Listeners, Karli M. Nave

UNLV Theses, Dissertations, Professional Papers, and Capstones

Synchronization to rhythmic stimuli is an everyday experience, whether it is exercising to the beat of music, dancing salsa, or rocking a baby to sleep. Commonly, humans synchronize their movements with the frequency of the beat (a quasi-isochronous pattern of prominent time points). Previous research has shown that the intended beat periodicity of a rhythmic stimulus can be observed in periodic neural activity; however, the extent to which this reflects robust perception of musical rhythm versus purely stimulus-driven activity is unknown. In Experiment 1 and 2, I investigated how long listeners can maintain a percept of the beat once the …

The Transformation Of American Federalism, 1848-1912, Lance Sorenson

UNLV Theses, Dissertations, Professional Papers, and Capstones

United States expansion following the Mexican-American War served as the catalyst for a reinvention of American Federalism. While much of the historiography traces the accretion of sovereign power in the national government to events caused by the divisions between northern states and southern states, there is an important and understudied East to West component of the process by which sovereign boundaries changed. The American West is a legal space where the hazily defined and capacious concept of federalism received fuller form and clearer definition. During the late nineteenth century and first few years of the twentieth century, the United States …

Understanding Stress Reactivity In Schizophrenia, Mary Vertinski

UNLV Theses, Dissertations, Professional Papers, and Capstones

The role of stress has long been recognized in schizophrenia; several theories have identified the role of stress as an important factor in the etiology of schizophrenia. A handful of studies have used laboratory psychosocial stressors to examine cortisol stress response in schizophrenia; the results obtained have consistently suggested that the stress response is attenuated in people with schizophrenia. Present study set out to examine stress responsivity in schizophrenia relative to healthy controls. A laboratory stress test was used to investigate cortisol response, heart rate and task appraisal in a sample of 17 healthy controls and 16 men diagnosed with …

Setting The Childless Free: An Ethnographic Study Of The Practice Of The Childfree Identity, Shelly Volsche

UNLV Theses, Dissertations, Professional Papers, and Capstones

Heeding Sherry Ortner’s call to turn anthropological analysis inward, toward one’s own culture, the following dissertation seeks to understand the identity and practice of the voluntarily childless (hereafter “childfree”) movement in the United States. How do these individuals practice their identity, and how does the identity of “childfree” interact with other roles in their lives? How do they build meaning in a society that emphasizes children as a hallmark of adulthood? What other outlets do childfree individuals have for the “nurturing” tendencies of our species?

Combining sociohistoric analysis with identity and feminist theories, I embarked on nearly two years of …
