Can Stress Build Relationships? Predictors Of Increased Marital Commitment Resulting From The 2007–2009 Recession, Jeffrey P. Dew, Ashley Lebaron, David Allsop
Can Stress Build Relationships? Predictors Of Increased Marital Commitment Resulting From The 2007–2009 Recession, Jeffrey P. Dew, Ashley Lebaron, David Allsop
Faculty Publications
Although some studies have examined factors that can help married couples maintain their relationship quality during financial stress, few have examined factors that might actually help marriages flourish during financial stress. This study examined participants’ reports of their commitment increasing because of the 2007–2009 Recession using dyadic data from a national sample of married couples. We found that religious marital sanctification, relationship maintenance behaviors, and social and financial support from family and friends were all related to both wives’ and husbands’ reports that their commitment had increased during the Recession. Wives who faced employment- or housing-related problems reported increased commitment. …

It’S Like Déjà Vu All Over Again: Seismic Changes In The American Experiment, David King
Bridge/Work
“I’ve never seen anything like this.” “Is this the end of the country?”
In 2016, it seemed that both of those statements, or something similar, was on the tongues of nearly every American. No matter who you supported, there seemed to be something entirely new about the election cycle that the nation found itself in. There is no doubt that for this generation, the 2016 election is a watershed moment for the United States. For the U.S., however, watershed moments in democracy are not the exception but the rule. To fully understand how our democracy transitions, one must return to …
Empathy Institutionalized: Sociocultural Dialogue As A Strategic Peacebuilding Initiative, Emily Owens
Empathy Institutionalized: Sociocultural Dialogue As A Strategic Peacebuilding Initiative, Emily Owens
Bridge/Work
A common adage used in psychological exploration tells us that “If you want to know the end, look at the beginning.” While typically employed to emphasize the importance of upbringing and environment on personal outcomes, this phrase can be equally applicable in examining the ways in which society has developed over time to produce our polarized sociopolitical culture of today. This work explores from an integrative psychosocial perspective the potential that exists in working to define a new “end” by shaping a new “beginning,” through going directly to the institutions that comprise our own beginnings— schools. Through a combined research …

Conversations That Matter: How A Thriving Public Sphere Makes Better Citizens And Better Neighbors, Kylie Schreiber
Bridge/Work
While it is true that the most recent presidential election cycle highlighted deeply rooted divisions lying in our American democracy, there is more to this separation than politics. Globalization and polarization have acted as catalysts, in part, to the decline of neighborliness and citizenship in America. I argue that a return to the “public” sphere in local communities can remedy this. This paper tests this theory by strategically selecting public policies and civic engagement activities that attempt to accomplish this goal of returning to the public and evaluating them on their ability to do so.
There are important questions about …
Are Florida's Children Safe? Evaluating Safety In District 7 Privatized Child Welfare Services, Antoinette Bazunu
Are Florida's Children Safe? Evaluating Safety In District 7 Privatized Child Welfare Services, Antoinette Bazunu
The Pegasus Review: UCF Undergraduate Research Journal
In 1998, the Florida state legislature mandated the privatization of child welfare services. The decision to contract child welfare services to non-profit organizations was instituted in an effort to lower costs and to increase the effectiveness and quality in service delivery. The 1998 initiative came to be known as "Community-Based Care" and was based on the idea of giving local communities incentives to be more accountable for children.
The federal government requires that the safety of all children be the paramount goal for the child welfare system. The purpose of this study was to assess whether Community-Based Care was indeed …

The purpose of this research is to better understand the attitudes of University of Central Florida students concerning the stereotypes, myths, and ideologies related to social class inequality. This research measures gender, race, social class, and level of exposure to the lower class as key factors in students' beliefs. The data were collected through the use of self-administered surveys distributed to 1496 UCF students from a variety of different colleges on the Orlando campus. The most significant findings were in relation to the "work hard, get ahead" ideology, as well as the equal opportunity myth. This is a non-probability sample; …
Undervoting And Overvoting In The 2002 And 2006 Florida Gubernatorial Elections, Javed Khan
Undervoting And Overvoting In The 2002 And 2006 Florida Gubernatorial Elections, Javed Khan
The Pegasus Review: UCF Undergraduate Research Journal
In a participatory democracy where every vote counts, voters expect that every vote will be counted. The voting machine is the instrument with which the voting public records its intent and appoints its representatives. In order for the democratic process to function, voting machines must properly function.
Do electronic voting systems that rely on touchscreens work better at reducing undervote and overvote counts than optical scan systems? To answer this question, an analysis of undervote and overvote counts in the 2002 and 2006 Florida Gubernatorial elections was conducted. The undervote and overvote counts across county, voting system, system manufacturer, and …
Gender Presentation And Membership Bias In Greek Organizations, Jason L. Metzger, Patrick Williams, Mailyn Chen, Genie Chartier
Gender Presentation And Membership Bias In Greek Organizations, Jason L. Metzger, Patrick Williams, Mailyn Chen, Genie Chartier
The Pegasus Review: UCF Undergraduate Research Journal
The study objective was to explore the possibility of discrimination and bias based on perceived gender presentation. In this study, subjects were female and male undergraduate students of both Greek and non-Greek affiliations at a University in the Southeastern United States. Subjects were asked to rate the probability of extending group membership to others based on perceived visual gender appearance. In the pilot study, 150 University of Central Florida students were polled to assess three categories of visual gender presentation in pictures: average gender presentation (typical female or male), extreme gender presentation (extremely feminine or extremely masculine) and non-traditional gender …

“I Want Her To Make Correct Decisions On Her Own:” Former Soviet Union Mothers’ Beliefs About Autonomy Development, Masha Komolva, Jane Y. Lipnitsky
Publications and Research
This qualitative study examined Former Soviet Union (FSU) mothers’ explicit and implicit attitudes and parenting practices around adolescents’ autonomy development. Interviews were conducted with 10 mothers who had immigrated from the FSU to the US between 10 and 25 years ago, and who had daughters between the ages of 13 and 17 years. Mothers predominantly defined autonomy in terms of adolescents’ ability to carry out instrumental tasks, make correct decisions, and financially provide for themselves, but rarely mentioned psychological or emotional independence. Mothers reflected on the various aspects of autonomy emphasized in their country of origin and America, and balancing …

Defining Place: A Review Of How Place Type Is Measured And Constructed, Kelly Rodgers
PSU Transportation Seminars
Part of the Student Presentations from TRB
Researchers have been parsing which components of the built environment contribute to outcomes of interest and to what degree, particularly the effects on vehicle use and walking. Increasingly, researchers and practitioners recognize that the type of neighborhood may affect individual travel behaviors. These bundle of various land use and transportation system characteristics can be constructed as different neighborhood or place types. But not all place types are constructed with the same use, purpose, or methods. This presentation will review three classifications of place typologies to better understand their purpose and appropriate application as …
Vocal Expression In Schizophrenia: Examining The Role Of Vocal Accommodation In Clinical Ratings Of Speech, Thanh P. Le
Vocal Expression In Schizophrenia: Examining The Role Of Vocal Accommodation In Clinical Ratings Of Speech, Thanh P. Le
LSU Master's Theses
Diminished vocal expressivity, defined in terms of a diminution in speech production and intonation/emphasis, is a chronic symptom in schizophrenia. On interview-based measures of vocal deficits, clinicians typically rate patients with schizophrenia 4 to 6 SDs below their non-patient peers. However, recent studies utilizing objective computerized measures have failed to observe vocal expressivity deficits that approach this level. It may be that vocal deficits can only be understood within the boundaries of dyadic exchanges during interview-based assessments. Vocal accommodation, or the degree to which vocal characteristics (i.e., mean F0) between interlocutors synchronize over time, has been linked to enhanced social …

Holocene Dynamics Of Temperate Rainforests In West-Central Patagonia, Virginia Iglesias, Simon G. Haberle, Andrés Holz, Cathy Whitlock
Geography Faculty Publications and Presentations
Analyses of long-term ecosystem dynamics offer insights into the conditions that have led to stability vs. rapid change in the past and the importance of disturbance in regulating community composition. In this study, we (1) used lithology, pollen, and charcoal data from Mallín Casanova (47°S) to reconstruct the wetland, vegetation, and fire history of west-central Patagonia; and (2) compared the records with independent paleoenvironmental and archeological information to assess the effects of past climate and human activity on ecosystem dynamics. Pollen data indicate that Nothofagus-Pilgerodendronforests were established by 9,000 cal yr BP. Although the biodiversity of the understory increased …
Inductive And Deductive: Ambiguous Labels In Qualitative Content Analysis, Mohammad Reza Armat, Abdolghader Assarroudi, Mostafa Rad, Hassan Sharifi, Abbas Heydari
Inductive And Deductive: Ambiguous Labels In Qualitative Content Analysis, Mohammad Reza Armat, Abdolghader Assarroudi, Mostafa Rad, Hassan Sharifi, Abbas Heydari
The Qualitative Report
The propounded dualism in Content Analysis as quantitative and qualitative approaches is widely supported and justified in nursing literature. Nevertheless, another sort of dualism is proposed for Qualitative Content Analysis, suggesting the adoption of "inductive" and/or "deductive" approaches in the process of qualitative data analysis. These approaches have been referred and labelled as "inductive" or "conventional"; and "deductive" or "directed" content analysis in the literature. Authors argue that these labels could be fallacious, and may lead to ambiguity; as in effect, both approaches are employed with different dominancy during the process of any Qualitative Content Analysis. Thus, authors suggest more …

Initiation, Desistence, And Recovery: A Qualitative Examination Of Self-Injury From A Life-Course Perspective, Thomas W. Wojciechowski
Initiation, Desistence, And Recovery: A Qualitative Examination Of Self-Injury From A Life-Course Perspective, Thomas W. Wojciechowski
The Qualitative Report
Self-injury is typically defined as the intentional harm caused to one’s own body. This phenomenon has historically been studied mainly from a psychological perspective and has focused less on social forces related to engagement in this behavior. While research on self-injury has examined etiology extensively, there has yet to be an examination of how changes in exposure to risk and protective factors may lead to changes in self-injury habits. This research uses qualitative interview data from 16 former and current self-injurers to examine self-injury from a life-course criminological perspective (Cullen, Agnew, & Wilcox, 2014). These data allowed for identification of …

Bonding And Bridging Forms Of Social Capital In Wildlife Tourism Microentrepreneurship: An Application Of Social Network Analysis, K. C. Birendra, Duarte B. Morals, Erin Seekamp, Jordan Smith, M. Nils Peterson
Environment and Society Faculty Publications
Tourism has been recognized as an important economic sector, requiring a high degree of involvement from the entrepreneurial sector to diversify tourism products and services to meet increasing demand. Tourism is often considered a tool for economic development and a strategy to improve the livelihoods of rural citizens. Specifically, nature-based tourism, such as wildlife tourism, is growing faster than tourism in general, providing a myriad of opportunities for small-scale entrepreneurial engagement. However, several obstacles exist for these small-scale tourism enterprises, such as a lack of social capital. This study examined a network of wildlife tourism microentrepreneurs for bonding and bridging …

Density Differences: Exploring Built Environment Relationships With Walking Between And Within Metropolitan Areas, Jamie Orrego
PSU Transportation Seminars
Part of the Student Presentations from TRB
To explore the relationships between measures of density and walking within and between urban areas, we present an analysis of the travel survey data from six different cities from the US and Santiago, Chile. The analysis of aggregate and disaggregate pedestrian trips presented here examine the potential consistency of relationships between walking and density within and across different regions, with a specific focus on population density. Our findings illustrate a relationship between population density and walk mode shares that is roughly linear and of nearly equal magnitude across US regions in densities below …

An Examination Of Factors That Affect The Utilization Of Mental Health Services By Adolescents, Nichole A. Murray
USF Tampa Graduate Theses and Dissertations
Mental disorders among adolescents are on the rise and are among the most common chronic conditions, constituting a national epidemic. Prevalence rates indicate that 20–40% of the adolescent population in the U.S. suffers from emotional or behavioral difficulties significant enough to lead to functional impairment. Further, estimates suggest that more than 20% of the adolescent population has a diagnosable mental disorder, which significantly impacts their functioning substantially at school, at home and in their communities. Despite national agendas to address the mental health needs of adolescents, studies suggest that approximately 50 percent of adolescents with mental health needs do not …

Hanging By A Thread: Enhancing The Forensic Value Of Dyed Cotton Trace Evidence Through The Application Of Novel Techniques In Fiber Discrimination, Rachel M. Russo
Hanging By A Thread: Enhancing The Forensic Value Of Dyed Cotton Trace Evidence Through The Application Of Novel Techniques In Fiber Discrimination, Rachel M. Russo
The Pegasus Review: UCF Undergraduate Research Journal
This thesis examines the capability of current techniques in fiber classification such as UV-visible microspectrophotometry (MSP) (for dye in situ and/or extracted) to discriminate between fibers from sources known to be different. When these methods fail to adequately distinguish the fibers, novel alternative techniques'such as pulsed pumped laser-induced fluorescence spectroscopy (LIF) and liquid chromatography-mass spectrometry (LC-MS)'are utilized to provide definitive forensic evidence.
The FBI Dye Extraction Classification and Chromatography Schemes: Forensic Fiber Examination Guidelines provides the methodology used by the majority of crime labs across the United States (Fong, 1984). In the case of cotton fibers'the most frequently encountered fiber …
