Concerning Millennials: Exploring Generational Cohort Effects on Racial Linked Fate, Religion and Politics, and Support for American Civil Liberities (open access)

Concerning Millennials: Exploring Generational Cohort Effects on Racial Linked Fate, Religion and Politics, and Support for American Civil Liberities

This research examines the political implications of the Millennial generation on American politics by exploring the interaction of generational cohort with race, social issues, and civil liberties. Relying on the 2016 Collaborative Multiracial Post-Election Survey and the 2018 General Social Survey, I examine (1) Millennial attitudes toward race and ethnicity by looking specifically at racial linked fate, (2) how Millennials interact with race and evangelical Christianity and how this interaction influences social policy preferences, and (3) how generational factors influence Millennial attitudes toward American civil liberties. I find that there are measurable effects of generational cohorts on the predicted value of Linked Fate for racial minority groups in the United States. My results suggest that Millennials are significantly more likely to have higher levels of linked fate for Latino and Asian Americans. However, I do not find sufficient evidence to suggest that African Americans' level of linked fate is affected either positively or negatively for Millennials. Second, for the investigation on social policy, the results suggest that those who sit at the intersection of the three groups- the Latino-Millennial evangelicals- hold policy preferences that contrast from those who are solely either Latino, Millennial, or evangelical. Latino-Millennial evangelicals are significantly more …

Three Essays on Size Premium Puzzle

Size premium puzzle, also known as the size effect, is one of the most studied anomalies in asset pricing literature. It refers to the observation that, on average, smaller firms have higher risk-adjusted returns than larger firms over a long period of time. While many studies have debated the existence of the size effect, the question of why it exists has become a subject of heated debate. Thus, this dissertation aims to examine if previously overlooked factors can, at least partially, explain the size effect. Essay 1 examines if merger and acquisition activity can explain a part of the size effect. I find that merger and acquisition activity explain a part of the size effect. The size effect is found to be stronger during merger waves but is not consistent across industries. Further, the size effect tends to be stronger when acquisition activity is concentrated among smaller firms. Essay 2 investigates if expectational errors explain the higher return of small firms. Several empirical studies show that stocks that investors underestimate yield higher returns. However, I do not find support for the underestimation explanation in explaining the higher returns of small firms. Instead, I find that investors are overly optimistic about …

Space Use, Microhabitat and Macrohabitat Use of the Three-Toed Box Turtle (Terrapene carolina) in North Texas (open access)

Space Use, Microhabitat and Macrohabitat Use of the Three-Toed Box Turtle (Terrapene carolina) in North Texas

Box turtle (Terrapene carolina) populations are steadily declining due their unique natural history, effects of climate change, and anthropogenic land use change. There is a need for updated information on box turtle space and micro and macro-habitat use to inform conservation efforts. This study used VHF radiotelemetry and GPS data loggers to examine box turtle space and habitat use in North Texas. Box turtle home range sizes averaged 6.6ha (range = 0.79 - 18.08, n = 23), and males (n = 9) had larger home ranges than females (n = 14; W = 31.5, P = 0.05). Home range size was best explained by a combination of variables including sex and body size, but overall, home ranges that consisted of higher percentages of suitable box turtle habitat were smaller. Box turtles used deciduous forest more than expected and wetlands less than expected by chance (Fisher's exact test, P < 0.0001). The most informative variable for box turtle macrohabitat selection was NDVI. Box turtles selected microhabitats with a higher percent litter (t = -2.16, P < 0.05) and understory cover (t = -5.03, P < 0.05). The results of CART analysis showed the nested importance of macro- and microhabitat and identified …

Middle Childhood Behavioral Attachment Dimensions (MCBAD):  Development and Validation of an Observational System for Coding Dimensions of Attachment Security in Middle Childhood (open access)

Middle Childhood Behavioral Attachment Dimensions (MCBAD): Development and Validation of an Observational System for Coding Dimensions of Attachment Security in Middle Childhood

Middle childhood is the least understood developmental period in the attachment literature, likely due to active reorganization of the attachment system during this stage. Coinciding with increased cognitive and socioemotional competencies, middle childhood attachment begins to transition from relationship-specific attachment to general attachment representations. While parents continue serving as the primary attachment figure used as a secure base and safe haven, noticeable shifts occur in terms of the need for availability over proximity to attachment figures and the child's involvement in maintaining the attachment relationship. Currently, there is no dominant conceptual or methodological approach for studying attachment in middle childhood. The present study sought to develop and validate an observational coding system examining middle childhood attachment using a dimensional approach. The Middle Childhood Behavioral Attachment Dimensions (MCBAD) system demonstrated mixed reliability and validity compared to other established attachment measures. Compared to traditional categorical attachment measures, this study provides evidence for the utility of an anxiety-avoidance dimensional attachment scale in childhood. Additionally, the MCBAD is the first observational system that examines both nonverbal and verbal attachment behaviors in an unstructured separation-reunion episode, and findings suggest a need for further examination of verbal attachment during this developmental stage.

Death Awareness and Meaningful Work: Considering Mortality and How It Relates to Individual Perceptions of Work

While some individuals experience their work as meaningful, others, with the same job, do not. The purpose of this dissertation is to answer the following question: Why do different individuals, with the same job, view the meaningfulness of their work in conflicting ways? I draw on terror management theory and generativity theory to answer this question by testing the relationship between death awareness and meaningful work. The bulk of academic work concerning meaningful work focuses on its outcomes and few scholars have explained the antecedents of meaningful work. This study aims to extend empirical work of the relationship between death awareness and meaningful.

How Much Does Sleep Vary from Night to Night? A Quantitative Summary of Intraindividual Variability in Sleep by Age, Gender, and Racial/Ethnic Identity

Habitual (i.e., average or typical) sleep duration and sleep efficiency vary widely by demographic characteristics, including age, gender, and racial/ethnic identity. Despite a wealth of studies on demographic patterns in habitual sleep, these results are often based on cross-sectional surveys, which ask participants to retrospectively recall their "typical" or "recent" sleep. Yet, sleep is a highly dynamic behavior and may fluctuate substantially from night-to-night. This intraindividual variability (IIV) in sleep/wake patterns can be captured a multitude of ways, most commonly by using formula-based calculations. Although there is growing attention on the importance of IIV in sleep, findings on demographic differences are still inconclusive, and there are no guidelines for typical values of IIV in sleep. The present study quantitatively synthesized 8 international data sets (N = 2847 participants, 29,832 total days of sleep data), focusing on examining age, gender, and racial/ethnic identity differences in IIV in sleep measured via sleep diaries, actigraphy, and electroencephalography. Sleep duration and sleep efficiency varied widely from night-to-night within people (duration: 64-119 minutes; efficiency: 5-8%). Different metrics of IIV were strongly correlated within and across sleep measurement types. Younger adults had more IIV in diary and actigraphy sleep duration. Gender differences in IIV in sleep …

Response to Regulation of Technology: A Multi-Industry Perspective

Overall my dissertation work tries to capture a holistic view of the various complex interactions that occur in technology development, implementation, adoption and diffusion, in the context of three industries by examining issues that arise due to regulation of technology. Essay 1 focuses on the social media industry, which is in the early stage of the industrial life cycle, and is the foci of government attention for its ill effect on society. Results from the study (N= 647 employed adults in the US) supported hypotheses related to the antecedents and outcomes of platform utilization in the context of the three regulation dimensions. Essay 2 focuses on the automotive industry, which is in the growth stage of the industrial life cycle. Here the focus is on electric vehicles (EV) transitioning from the niches to the main market. Results from the longitudinal study (N = 429) support the moderating role of political activism on innovation capability of manufacturers and presence of ancillary services in the diffusion of different types of electric vehicles in the US market. Essay 3 focuses on the US healthcare industry, reflecting mature stage of industrial life cycle, yet also characterized with high cost and fragmentation of service. The …

Politics in Uniforms: Military Influence in Politics and Conflictual State Behavior

This dissertation examines how the state-building process relates to civil-military relations and how political influence of the military affects state's conflict behavior. By doing so, this study aims to introduce a nuanced consideration of the well-known civil-military problematique, which might be summarized as the threat the military can constitute to the polity that it is created to protect. I treat this paradox by addressing the following research questions: Why do some militaries have a qualitatively higher level of influence in politics than others? Second, how does the military's influence in politics affect a state's domestic conflict behavior? And third, how does it affect state's international conflict behavior? I develop a theory that when the military is heavily involved in the state-building process, it gains an unusual place within politics, gets itself imprinted in the DNA of the state, and gains undue political power. I name such militaries as state-builder militaries and argue that such states experience qualitatively different civil-military relations, in which the military acts as an extremely Praetorian institution. I argue that state-builder militaries would be able to insulate their political power from the democratization process that the country might experience and behave as persistent interveners in politics. I …

Executive Functioning Processes in Simple and Complex Theory of Mind Tasks (open access)

Executive Functioning Processes in Simple and Complex Theory of Mind Tasks

Using a multimethod-multimodal approach, this study compared the contributions of executive function (EF) abilities (Go No-Go, Visual Search, 2-Back task, and Task Switching) to narrative comprehension tasks (False Belief, Strange Stories, Self-Reported Theory of Mind Inventory [TOMI-SR]) and a narrative production task (interpersonal decentering) in a sample of young adults. Separate regression models were conducted for each theory of mind (ToM) measure with EF measures as predictor variables and empirically selected demographic variables controlled. As expected, in this college student sample (N = 110), False Belief demonstrated a ceiling effect and was not associated with any EF ability. Task Switching and 2-Back accounted for significant variance in Strange Stories. No EF task significantly predicted performance on TOMI-SR or interpersonal decentering. Both story comprehension tasks (False Belief and Strange Stories) were significantly associated, but these tasks were not correlated with either self-reported ToM or interpersonal decentering. Several unanticipated demographic associations were found; having more siblings and English proficiency accounted for significant variability in Strange Stories; education, presence or absence of self-disclosed autism diagnosis and mental health diagnosis explained a large portion of variance in TOMI-SR; interpersonal decentering maturity differed significantly between cisgender men and cisgender women. Lastly, interpersonal decentering number of …

Elite Management Strategies under Dictatorships and Their Determinants (open access)

Elite Management Strategies under Dictatorships and Their Determinants

This dissertation attempts to uncover systematic patterns regarding elite management in dictatorships. To do so, it describes how dictators manage their elites and what factors determine the outcomes of their decision. Although considerable literature has examined the various structural features of dictatorships and has identified different elite management strategies to explain the persistence of dictatorships, few, if any, have empirically tested any of the theoretical propositions generated by this increasingly large body of literature. This dissertation is the first empirical attempt to explore the elite management strategies of various dictatorships, ranging from the individual case of the most extreme dictatorship (North Korea) as well as different kinds of military dictatorships (South Korea), and global patterns of autocratic regimes. To address the main research question, "what determines the choice of the dictator's elite management strategies?" this dissertation identifies three key factors - dictator, elites, and structure. The relationship between dictators and elites is basically hostile. Conflicts between actors over power acquisition often emerge in violent ways. Nevertheless, dictators do not always treat elites with repression. They sometimes make efforts to embrace and cooperate with the other elites. The variation of their strategies toward elites is determined by various conditions. The results …

Vocal Fold Onset and Its Effect on the Spectral Envelope

The purpose of this study is to examine the acoustic implications of using aspirated, well-coordinated, coup de la glotte, and hard glottal onset methods, in order to compare and contrast the radiated acoustic spectra. Twenty-five singers trained in bel canto singing style were asked to sing 5-second samples on three pre-determined pitches comprising the low, middle, and high range in male and female voices. Each participant was instructed and trained to sing the three pitches with the four methods. EGG was used with audio perception to verify onset type, and VoceVista Video Pro was used to analyze power spectra. A repeated measures multivariate analysis of variance (rMANOVA) was performed with the SPSS General Linear Model function, with onset type as the within-subjects variable to determine main effects and interaction effects on harmonic amplitude (up to 5000Hz) from the independent variables. A significant main effect was found for onset type and more specifically, a significant acoustic difference was found between the well-coordinated and coup de la glotte onsets. Substantial inconsistencies were found in the execution of the well-coordinated onset, as well as in participants' reported preferred onset compared to their baseline measurement of executed onset type. Intentional study of the phonatory …

A Multi-Level Model for Perception Affect Asymmetry: Individual, Dyadic, and Group Affect Dynamics

In collective affect research, an assumption is often made that through processes such as emotional contagion and attraction-selection-attrition members will converge unto a shared group affective tone. While this assumption is not without warrant, a limitation of previous work on interpersonal emotional processes of individuals, individuals within dyadic relationships, or members within teams is the lack of examination into the varying perceptions individuals may form regarding these affective experiences. To examine the development and influence of these affective perceptions, we extend recent works from work group conflict literature to examine the influence of perception asymmetry when applied to affective interactions. Wherein, we describe a novel construct of Perception Asymmetry of Affect (PAA). PAA refers to the congruence (e.g.; low level of PAA) or incongruence (e.g.; high level) of perceptions of positive and negative affective experiences between two or more individuals. This paper explores the following questions: 1) does perception asymmetry of affect exist; 2) if so, what causes perception asymmetry between individuals and their groups, within dyads, and within groups. This article contributes to literature on collective affect by offering a detailed framework for an understudied phenomenon of diverging or asymmetric perceptions.

Premigratory Experiences and the Political Effects of Suitcase Socialization

Do the experiences that an immigrant faces in their country of origin affect the political attitudes and behavior when an immigrant is in their country of residence? Although there is a considerable amount of work exploring the political behavior of racial and ethnic minorities, some work on immigrant political behavior, and some work that that connects premigratory experiences with post migration political behavior, there is relatively little work that examines premigratory experiences with autocracy, corruption, and violence and how that affects the political behavior of immigrants. In this project I observe how experiences with corruption, political violence, and conflict has an affect on political trust, political behavior, and social trust among immigrants that have experienced such events.

Students' Perceptions of Learning Environment and Achievement with Augmented Reality Technology

The purpose of the study was to examine the impact of using AR in the Computer Architecture unit for male 11th grade students in a school in the eastern area of Arar City in Saudi Arabia through monitoring its impact on student achievement and students' perceptions of the learning environment. Two research questions are explored: What is the effect of using AR on student achievement, and what are students' perceptions of the learning environment when they use AR? Two instruments were used to collect the data in this study: an achievement test taken from the official teacher book issued by the Ministry of Education in Saudi Arabia and the Technology-Rich Outcomes-Focused Learning Environment Inventory (TROFLEI) modified questionnaire "actual form." Statistical analyses employed to answer the first research question included an independent-samples t-test and descriptive statistics. To investigate the second research question, descriptive statistics and a paired t-test were used. These results from the first question indicate a statistically significant difference (p < 0.05) between the two groups' mean values: the students who used AR achieved a higher level of learning compared to the students who learned in the traditional way. The study found that using AR helped the students to …

Adaptation and Validation of the Athletic Identity Measurement Scale for Use with Musicians (open access)

Adaptation and Validation of the Athletic Identity Measurement Scale for Use with Musicians

Identity is a powerful concept that influences behavior and health. For over thirty years, researchers in sport psychology have been using the Athletic Identity Measurement Scale (AIMS) as a research instrument providing insights into the relationships between athletic identity and health variables. While musician identity is recognized as an important factor to be investigated in relation to occupational health, there are no known robust instruments like the AIMS in music psychology research. The current study aimed to adapt and validate the athletic identity measurement scale for use with musicians. The AIMS history includes episodes of modifications for performance enhancement of the instrument that resulted in five different models. The validation process includes evaluating the psychometrical properties across all five models. The sample included student musicians and non-student musicians (N = 1040). The traditional confirmatory factor analysis (CFA) and the maximum likelihood (ML) estimation method were used. The exploratory structural equation modeling (ESEM) and robust weighted least squares (WLS) was utilized to explore a new method of estimation that was known to resolve issues consistent with the CFA and ML method. The goodness-of-fit indices of CFA and ESEM were compared. The results showed that the MIMS is a reliable and valid …

Multi-Level Effects of Oxygen Exposure in Endothermic Insects (open access)

Multi-Level Effects of Oxygen Exposure in Endothermic Insects

This dissertation examined the phenotypic plasticity of endothermic, flight and respiratory physiology in response to developmental oxygen exposure in the moth Manduca sexta. Development in both 10% O2 hypoxia and 30% O2 hyperoxia treatments were used to look at the physiological consequence on both ends of the oxygen spectrum. Hypoxic insects reached smaller sizes as adults and had longer pupation lengths than controls. Hyperoxic insects were larger at the end of the larval stage, had increased larval growth rates, but also had longer developmental larval developmental times and pupation lengths than controls. There was a decrease in both metabolic rate and thorax temperatures of hypoxic reared insects at normoxic levels. In flight trials hypoxic insects had the lowest critical flight PO2, and the hyperoxic insects had the highest PO2. There was an increase in hypoxic insect flight muscle mitochondria oxygen consumption in permeabilized fibers, but this did not translate to the isolated flight muscle mitochondria metabolic rates. Rearing oxygen level did not significantly affect mitochondrial density and size; myofibril density and size, or tracheal density and size in flight muscle. Overall, I found that higher levels of organization were more susceptible to the effects of chronic oxygen exposure and found …
