Exercise, Learning And Emotional Health: Interdisciplinary Approaches To Translational Action, Tessa L. Koschel

UNLV Theses, Dissertations, Professional Papers, and Capstones

Exercise positively effects physical, psychological and neurological wellbeing. Though the population at large is becoming increasingly aware of the multi-faceted benefits of exercise, the majority of people fail to meet daily exercise recommendations. Largely, demands of everyday life such as work, school and family take priority over fitness. The issue therefore becomes a matter of time. In a world of media multi-tasking and immediate gratification, the challenge to health professionals becomes incorporation and manipulation of these consistencies to improve exercise uptake and adherence. Focus must shift from the idea of making additional time for exercise, to adding exercise to time …

Latino Lgbq Young Adults' Coming-Out Experiences, Monica Munoz

UNLV Theses, Dissertations, Professional Papers, and Capstones

There is limited research on Latino LGBQ individuals and their coming-out experiences. To understand the coming out process of Latino LGBQ individuals, interviews were conducted with 10 Latino LGBQ young adults between the ages of 18 and 30 years old. Using Moustakas (1994) phenomenological approach, six themes derived from the study: (a) The disclosure process impacts family closeness and distance, (b) Latino LGBQ individuals’ family members enter a state of disbelief about their sexual orientation, (c) control of disclosure influences Latino LGBQ young adults’ perception of their coming-out experience, (d) the experience of coming-out for Latino LGBQ individuals is influenced …

The Balance Between Privacy And Safety In Police Uav Use: The Power Of Threat And Its Effect On People’S Receptivity, Mari Sakiyama

UNLV Theses, Dissertations, Professional Papers, and Capstones

Unmanned aerial vehicles (UAVs), also known as drones, are an innovative technology that has received significant interest from the law enforcement community. The size and ability, technological capability, and cost effectiveness of UAVs make them an attractive tool for law enforcement agencies to utilize in the course of operations, including domestic surveillance. Despite the potential benefits to the society, public perception of police UAV use is mixed, and “Not Over My Backyard (NOMBY)” attitudes relevant to Fourth Amendment privacy concerns are consistently demonstrated across studies related to public perceptions on this emerging technology.

The present study focuses on the relative …

Associations Among Benevolent Sexism, Relationship-Contingent Self-Esteem, And Relationship Maintenance Strategies In Heterosexual Women, Carrie Underwood

UNLV Theses, Dissertations, Professional Papers, and Capstones

Past research shows that heterosexual women who endorse benevolent sexism (a sex-role attitude) tend to be highly invested in romantic relationships (Lee, Fiske, Glick, & Chen, 2010). Consequently, they may be more likely than other women to remain in relationships that are troubled. The current study aimed to shed light on this possibility by examining whether benevolent sexism was associated with the relationship maintenance strategies that women use in troubled relationships. I presented women with a scenario of a troubled relationship and manipulated the type of sexism the male partner in the scenario endorsed. Repeated measures ANCOVA revealed that women …

Worked To Leisure: The Intersections Of Volunteerism, Work, And Leisure, Denise Nicole Cook

UNLV Theses, Dissertations, Professional Papers, and Capstones

Volunteerism and work are topics which academics in several disciplines research. This study is an examination of the intersection of work and volunteerism via the lens of role theory. According to role theorists, the term role refers to behaviors which are either a result of social position or expectations (Biddle 1986). Cognitive role theorists use vocabulary such as “role conflict” and “role overload” to identify incongruences sometimes found in roles individuals have in their lives (Biddle 1986). These incongruences are primarily examined as they relate to individual level consequences. This research explores volunteerism and work as they relate to role …

Sex Worker And Proud: A Phenomenological Study Of Consensual Sex Workers' Lives, Michael Gerald Curtis Jr.

UNLV Theses, Dissertations, Professional Papers, and Capstones

Ten consensual sex workers who were currently working in Nevada were qualitatively interviewed in an effort to explore their perceptions of the adult industry. Interviews specifically focused on their experience disclosing their profession to others and the potential effects that it has on their personal relationships, and access to effective treatment. The Moustakas method of phenomenological inquiry was used to analyze data from ten participants who self-identified as direct sex workers. Seven essential themes emerged from this analysis: (1) the adult industry provides professional and personal agency, (2) the industry is often transient, (3) disclosure is an impactful and ongoing …

Relationship Between Work-Family Conflict, Job Embeddedness, Workplace Flexibility, And Turnover Intentions, Bilal Afsar, Zia Ur Rehman

Makara Human Behavior Studies in Asia

The present study seeks to propose and test a research model that investigates job embeddedness as a mediator and workplace flexibility as a moderator of the effect of family-work conflict on turnover intentions. This study uses a survey method and a structured questionnaire to collect data from 187 nurses working in various hospitals in Islamabad, Pakistan. The results showed that on-the-job embeddedness partially mediated the effect of work-family conflict on nurses’ turnover intention. Furthermore, workplace flexibility moderated the relationship between work-family conflict and turnover intention. Management of the hospitals should take decisive steps to establish and maintain a supportive and …

Communicating Seismic Risk: The Geoethical Challenges Of A People-Centred, Participatory Approach, Is Stewart, J Ickert, R Lacassin

School of Geography, Earth and Environmental Sciences

The Sendai Framework for Disaster Risk Reduction (SFDRR) encourages scientists to participate in bottom-up risk communication approaches that directly engage hazard-prone populations. Effective communication of seismic risks not only has economic impacts in terms of hazard mitigation but also provides social value in potentially empowering the marginalized populations that disproportionately live in high-risk areas. This emphasis on community-focused disaster preparedness, however, presents a novel set of communication challenges for geoscientists. Few scientists have training in or experience of translating their science for lay publics, and conveying complex risk information is especially difficult in circumstances where scientific issues are socially contested …

Establishing The Theoretical Components Of Alexithymia Via Factor Analysis: Introduction And Validation Of The Attention-Appraisal Model Of Alexithymia, David Preece, Rodrigo Becerra, Alfred Allan, Ken Robinson, Justine Dandy

Research outputs 2014 to 2021

Alexithymia is an important mental health construct, but there is continuing debate regarding its definition and measurement. We attempt to resolve this definitional uncertainty in two ways. Firstly, we trace the development of the alexithymia construct, focusing particularly on what we call the Toronto and Amsterdam models, and examine a body of empirical research that shows strong support for the hypothesis that alexithymia consists of three components (difficulty identifying feelings, difficulty describing feelings, and externally orientated thinking). Based on these components, we formulate an alternate theoretical model of alexithymia, the attention-appraisal model of alexithymia, that aligns alexithymia theory with …

Policy Advocacy: Standards For Professional Learning, Emily Crement

Dissertations

This paper advocates for a district level policy the Standards for Professional Learning as a way of defining what high quality professional learning should look like. The Standards for Professional Learning represent a compilation of decades of research on what characterizes effective professional learning. Since improvements in professional learning will lead to large scale school improvement, this paper concludes that the Standards be used to define effective professional learning. Presented in this paper is an analysis of need from the educational, economic, political, social and ethical perspectives. An argument in favor of adopting the standards is presented, and a counterargument …

The Impact Of Researchers’ Perceptions Of Insecurity And Organized Crime On Fieldwork In Central America And Mexico, Dawid K. Wladyka, William Yaworsky

Sociology Faculty Publications

This article explores field researchers’ perceptions of field site security and causes of fieldwork disruption. We seek to quantify what phenomena are decisive in perceiving a field site insecure and to gauge whether researchers find rural or urban areas to be more secure from organized criminal violence. We also identify the conditions that best predict scholars’ willingness to abandon research in any given region. To do so, we use a regression analysis of the results of a survey administered to anthropologists working in Mexico and Central America. The article reveals that anthropologists view urban areas as being less secure and …

Using Multicultural Children’S Literature To Address Social Issues: The Power Of Interactive Read Aloud, Rebekah E. Piper, Ramona T. Pittman, Tasha A. Vice

Reading Faculty Publications (Archived)

As the demographics of U.S. schools are changing, educators have to embrace this change and prepare students to adopt diversity and inclusivity as a means to increase students’ understanding of their peers. Not only are race and ethnicity identities at the forefront of these changes, gender identity and ability identity must also be supported, as more students are challenging traditional gender roles and as more students are mainstreamed into regular education classes. This article seeks to address usage of interactive read alouds of multicultural literature as a means to help bridge students who need inclusive
and equitable pedagogical practices in …

Functional Isolation: Understanding Isolation In Trafficking Survivors, Liz Mahan

Student Theses

This study examined how traffickers used different elements of isolation and how such tactics may have contributed to the traffickers’ success in maintaining control over the victim. I examined in-depth narratives from 14 women between the ages of 20-53, primarily immigrants, who were recruited from an agency serving victims of sex trafficking in a large metropolitan city. The tactics used by traffickers varied and included not only the commonly defined structural isolation in which victims are restricted physically and socially, but also included a shrinking of safe social space and an elimination of privacy and social support. The latter is …

The Growth, Structure, And Dynamics Of Crime In Cities, Marcos Oliveira

Theses and Dissertations

Crime is ubiquitous in cities but lacks a statistical characterization that could lead to uncovering its underlying mechanisms. Cities are, however, in a constant process of organization making difficult to analyze urban phenomena. Yet, to understand urbanization and its consequences, we need to approach cities as evolving processes, instead of static objects. With this perspective, we examined regularities in crime regarding its growth, structure, and dynamics. We developed frameworks to examine the spatial, temporal, and periodic variations of crime in cities. Though thefts increase super-linearly with the population, we found burglaries showing a linear increase. Our analyses also confirmed crime …

Information Densification Of Social Constructs Via Behavior Analysis Of Social Media Users – A Study On Twitter, Diogo F. Pacheco

Theses and Dissertations

We live in a digital era where everyday activities are increasingly being replaced by online interactions. In addition, technology advances and data availability are changing the way we expand our knowledge about ourselves, society, and the environment. The increasing availability of data, especially social media data, has called the attention of researchers, and we have been witnessing an outbreak in studies relying on this rich source of information. However, most social media research is tuned to improve the outcomes of specific problems. Therefore, the reuse of techniques used in different areas is limited to data specialists. We propose a straightforward …

Comparing Methods Of Targeting Obesity Interventions In Populations: An Agent-Based Simulation, Rahmatollah Beheshti, Mehdi Jalalpour, Thomas A. Glass

Civil and Environmental Engineering Faculty Publications

Social networks as well as neighborhood environments have been shown to effect obesity-related behaviors including energy intake and physical activity. Accordingly, harnessing social networks to improve targeting of obesity interventions may be promising to the extent this leads to social multiplier effects and wider diffusion of intervention impact on populations. However, the literature evaluating network-based interventions has been inconsistent. Computational methods like agent-based models (ABM) provide researchers with tools to experiment in a simulated environment. We develop an ABM to compare conventional targeting methods (random selection, based on individual obesity risk, and vulnerable areas) with network-based targeting methods. We adapt …

Physical Aggressiveness And Gray Matter Deficits In Ventromedial Prefrontal Cortex, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall

Psychology Faculty Publications

What causes individuals to hurt others? Since the famous case of Phineas Gage, lesions of the ventromedial prefrontal cortex (VMPFC) have been reliably linked to physically aggressive behavior. However, it is unclear whether naturally-occurring deficits in VMPFC, among normal individuals, might have widespread consequences for aggression. Using voxel based morphometry, we regressed gray matter density from the brains of 138 normal female and male adults onto their dispositional levels of physical aggression, verbal aggression, and sex, simultaneously. Physical, but not verbal, aggression was associated with reduced gray matter volume in the VMPFC and to a lesser extent, frontopolar cortex. Participants …

Effects Of Environmental Enrichment On Self-Administration Of The Short-Acting Opioid Remifentanil In Male Rats, Rebecca S. Hofford, Jonathan J. Chow, Joshua S. Beckmann, Michael T. Bardo

Psychology Faculty Publications

Background

Opioid abuse is a major problem around the world. Identifying environmental factors that contribute to opioid abuse and addiction is necessary for decreasing this epidemic. In rodents, environmental enrichment protects against the development of low dose stimulant self-administration, but studies examining the effect of enrichment and isolation (compared to standard housing) on the development of intravenous opioid self-administration have not been conducted. The present study investigated the role of environmental enrichment on self-administration of the short-acting μ-opioid remifentanil.

Methods

Rats were raised in an enriched condition (Enr), standard condition (Std), or isolated condition (Iso) beginning at 21 days of …

The Psychological Health Of Airline Pilots: A Flight Deck Crew’S Perceptions And Willingness To Fly, Jason Charles Herkimer

Theses and Dissertations

Pilots have an image of bravado and charisma which includes that of a hardened, unemotional professional. What happens when the inevitable hardship occurs to a pilot? In the past, physical attributes were highly sought after in the recruitment of pilots. Eventually, pilots can and will suffer from the same psychological stressors as the general population. The purpose of this study is to determine the effect stigmatizing attitudes and psychological treatment of pilots have on a flight deck crew’s willingness to fly. The current study incorporated several different methodologies including a between subjects true experimental, an analysis of covariance (ANCOVA), an …

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

Voice Of A “Seasoned” Ob Professor, Fred Luthans

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 …

Attitudes And Perceived Legitimacy Of Police: Crises, Responses, And How Race Influences Perceptions, Brigitte Bonaci

Theses and Dissertations

Public relations is a strategic field because an organization may need to structure a message with the intent of persuading the public and making it respond to a crisis and a message in a certain way. This study will help introduce the concept of a lingering crisis that is hardly present in research and could be put under the public relations umbrella. Using a survey of communications students, this study will compare the public attitudes and perceptions of perceived legitimacy of a police department after it experiences one of three crisis types, one of which being a lingering crisis. Attitudes …
