'The Marshall System' in World War II, Myth and Reality: Six American Commanders Who Failed

This is an analysis of the U.S. Army's personnel decisions in the Second World War. Specifically, it considers the U.S. Army Chief of Staff George C. Marshall's appointment of generals to combat command, and his reasons for relieving some generals while leaving others in place after underperformance. Many historians and contemporaries of Marshall, including General Omar N. Bradley, have commented on Marshall's ability to select brilliant, capable general officers for combat command in the war. However, in addition to solid performers like J. Lawton Collins, Lucian Truscott, and George S. Patton, Marshall, together with Dwight D. Eisenhower and Lesley J. McNair, often selected sub-par commanders who significantly underperformed on the battlefield. These generals' tactical and operational decisions frequently led to unnecessary casualties, and ultimately prolonged the war. The work considers six case studies: Lloyd Fredendall at Kasserine Pass, Mark Clark during the Italian campaign, John Lucas at Anzio, Omar Bradley at the Falaise Gap, Courtney Hodges at the Hürtgen Forest, and Simon Bolivar Buckner, Jr. at Okinawa. Personal connections and patronage played strong roles in these generals' command appointments, and often trumped practical considerations like command experience. While their superiors ultimately relieved corps commanders Fredendall and Lucas, field army and …

Return to Sport: The Effects of Mindful Self-Compassion and Imagery on Subjective Physical Functioning and Psychological Responses Post-ACL Surgery (open access)

Return to Sport: The Effects of Mindful Self-Compassion and Imagery on Subjective Physical Functioning and Psychological Responses Post-ACL Surgery

In the current study, I examined the efficacy of mindful self-compassion, imagery, and goal-setting (i.e., treatment as usual) interventions on athletic identity, knee self-efficacy, subjective knee functioning, and perceived injustice, following ACL surgery. Twenty-nine adolescent and young adult athletes participated in the interventions and completed self-report measures assessing each of these constructs prior to their surgery and over seven weeks post-ACL surgery. HLM analyses demonstrated significant decreases in athletic identity and increases in subjective knee functioning from pre-surgery through seven weeks post-surgery. Intervention group further explained these decreases, though no one intervention clearly emerged as more or less beneficial. No significant changes were observed for athletes' ratings of knee self-efficacy or perceived injustice. Limitations and areas for future research are discussed.

Eagles Overhead: The History of US Air Force Airborne Forward Air Controllers, from the Muese-Argonne to Mosul

Eagles Overhead provides a critical history of US Air Force Forward Air Controllers and examines their role, status, and performance in the Air Force's history. It begins by examining the US's initial adoption of air power, and American participation in aerial combat during World War I and traces the FACs' contributions to every US Air Force air campaign from the Marne in 1918 to Mosul in 2017. However, since 2001 FACs' contributions have been sporadic. Eagles Overhead asks why, despite the critical importance of FACs, have they not been heavily used on US battlefields since 2001? It examines the Air Force FAC's theoretical, doctrinal, institutional, and historical frameworks in the first nine chapters to assess if the nature of air warfare has changed so significantly that the concept and utility of the FAC has been left behind. Or, has the FAC been neglected since 2001 because the Air Force dislikes the capability as it clouds the service's doctrinal preferences? From these examinations, Eagles Overhead draws conclusions about the potential future of Air Force FACs.

Three Essays on Employee's Personal Resource Allocation Decisions in Work and Life

Due to changes in workforce structure, household structure and the nature of jobs, today's working adults face the challenge of balancing their work and life. However, employees do not only passively react to the incompatible demands from work and life - they are active agents who make decisions about their own total life. For example, individuals make decisions about the amount of energy that they spend on work/life (WL) activities. Thus, I write three essays to understand the antecedents and consequences of employees' personal resource allocation decisions. In the first essay, I study the decision itself. That is, I identify and examine four profiles of employees' WL behavioral involvement. The studied behaviors include job behavioral involvement, organizational citizenship behavior, and life involvement. In Essay 2, I examine the antecedent of the behavioral involvement decisions – WL value, which is expressed as centrality, importance, and priority. Although an individual's behavior is argued to be directed by value, it cannot be fully understood without considering the context. Thus, I examine the influences of three external factors, including financial pressure, job demands, and perceived organizational supportive culture, on the value-behavioral involvement relationship. In Essay 3, I focus on the consequences of individuals being …

Achievement Motivation Theory as a Model for Explaining College Athletes' Grit (open access)

Achievement Motivation Theory as a Model for Explaining College Athletes' Grit

This study examined the direct and indirect associations of the perceived coach-created motivational climate, athletes' implicit theory, and athletes' achievement goal orientation in relation to their levels of grit. Five hundred twenty-three Division I and II collegiate student-athletes (male = 246, female = 277) from five institutions across the south-central and southeast areas of the United States completed self-report measures assessing the previously described constructs. The measurement model fit the data well (SRMR = .055; CFI = .938; RMSEA = .067) and demonstrated invariance across the male and female athletes. The structural model demonstrated adequate fit (SRMR = .088; CFI = .918; RMSEA = .068). All direct and indirect paths in the model were significant in the expected direction, with the exception of the direct path from entity theory to ego goal orientation and the indirect path from ego-involving climate to ego goal orientation through entity theory, which were both non-significant. The mastery-incremental constructs accounted for 65% of the variance in grit. Results indicate that achievement motivation theory is an appropriate framework through which to examine grit, and achievement motivation constructs may be significant antecedents of grit's development. Limitations and future directions are discussed.

Metabolic Responses to Crude Oil during Very Early Development in the Zebrafish (Danio rerio)

The present study sought to determine some morphological and physiological critical windows during very early development in zebrafish exposed to crude oil. I hypothesized that exposed zebrafish would present a decrease in survival rate and body mass, and an increase in routine oxygen consumption (ṀO2), and critical oxygen tension (PCrit). To test these hypotheses, zebrafish were acutely exposed (24 h) during different days of development (1 to 6 days post-fertilization, dpf) to different concentrations of high-energy water-accommodated fractions (HEWAFs). The endpoints of survival, body mass, routine oxygen consumption, and critical oxygen partial pressure were measured at 7 dpf. Survival rate decreased based on the exposure concentration but not as a function of the day of crude oil exposure. No significant effects were found in PCrit. Body mass was reduced by the different concentrations of HEWAF, with the size of the effect varying with exposure day, with the effect strongest on when exposure occurred at 2 and 3 dpf. Oxygen consumption (ṀO2) differed significantly depending upon the day of exposure in fish exposed to crude oil. Specifically, HEWAF exposure significantly increased ṀO2 in larvae exposed at 3 dpf (9.081 µmol O2/g/h, ±0.559) versus 2 dpf (6.068 µmol O2/g/h, ±0.652) and 6 …

Improving Athletes' Confidence and Mindset Post-ACL Reconstructive Surgery (open access)

Improving Athletes' Confidence and Mindset Post-ACL Reconstructive Surgery

Tears to the anterior cruciate ligament (ACL) represent a serious sport injury that can be physically and psychologically debilitating for athletes. Recovery from ACL surgery is a six to nine month process, though the first four months of rehabilitation represents the key time of recovery. Thus, psychological interventions should occur during these first four months, but then examine athletes' psychological and physical functioning over the longer term. Past research has supported the efficacy of goal setting and imagery in helping athletes during their ACL recovery, and MSC has been shown to help athletes regulate emotions and improve their sport performance. MSC-based interventions, however, have not been examined in relation to injured athletes' psychological functioning and physical recovery. Thus, I examined the relative effects of three psychological interventions (i.e., GS, IM, and MSC) on athletes' post-ACL responses. Overall, I found no significant differences in the effects of GS, IM, or MSC on athletes' athletic identity, confidence in returning to sport, reinjury anxiety, stress related to sport injury, perceptions of ability to cope with injury, and subjective knee functioning. Although non-significant, athletes in the GS group showed slightly larger rates of change in their reinjury anxiety and cognitive appraisal compared to athletes …

Effect of Trauma-Related Stress during Acute Alcohol Intoxication on Driving-Related Risky Decision-Making (open access)

Effect of Trauma-Related Stress during Acute Alcohol Intoxication on Driving-Related Risky Decision-Making

Alcohol-related motor vehicle crashes are a major preventable cause of death in the United States. One potential factor that may modulate the influence of alcohol intoxication on driving-related decision-making is posttraumatic stress. The current study evaluated the influence of induction of acute trauma-related stress (via script-driven imagery) during alcohol intoxication (.06% BrAC) on driving-related risky decision-making – willingness to drive, driving-related decision-making (i.e., attempted red light runs), and driving-related reaction time (i.e., braking latency) – among 56 trauma-exposed (currently symptomatic) adult drinkers from the community (M = 25.32; 46.4% female). Results indicated that trauma-related stress may exacerbate willingness to drive during a state of acute alcohol intoxication, but, alternatively, may have only a minimal-to-moderate effect on performance-based, driving-related decision-making (i.e., red light runs), and a potentially mitigating impact on driving-related reaction time (i.e., braking latency) under the influence of alcohol. Generally, results suggest that trauma-related stress may differentially impact varying aspects of driving-related risky decision-making, above and beyond the influence of alcohol. Implications for theoretical modeling for driving-related decision-making during acute intoxication and for the advancement of education and intervention efforts, as well as suggestions for future directions, including methodological and procedural improvements, are discussed.

Multifactorial Determinants of Change in Mental Disorder and Happiness among Older Americans

Mental health is an intrinsic capability that constitute an essential component of healthy aging. Mental health is constituted by positive constructs such as happiness and negative constructs (mental disorders) such as depression. As people grow older, they become more prone to developing mental disorders which are linked to poorer quality of life, increased disability, increased utilization and cost of health services, and higher rates of suicide. This dissertation involved three studies that focused on factors that predict change in mental disorders and happiness of older Americans over a period of five years. Two waves of publicly available national representative data from the National Social Life Health and Aging Project (NSHAP) collected in 2010 and 2015 were used. A total of 2210 older adults within the ages 62-90 years were used in the analyses. Mental health measures were CES-Depression scale, HADS anxiety scale, and self-rated happiness. Essay 1 aimed to identify the important aspects of older adults' interaction with their neighborhood that predict the presence of mental disorder and happiness. Essay 2 evaluated the psychosocial factors that predict change in mental disorder and happiness of older adults, whereas essay 3 investigated the multifactorial determinants of change in mental disorder and happiness …

An Analysis of Information Technology (IT) Post-Adoption Behavior

The primary focus of this research is explicating the role of emotion in IT post-adoption behavior. Studied in the context of intelligent personal assistants (IPA), a class of conversational artificial intelligence (AI), the first study integrates elements from computer science, communications, and IS disciplines. The research identifies two constructs vital for speech-based technologies, natural language understanding, and feedback, and examines their role in use decisions. This work provides guidance to practice on how best to allocate R&D investments in conversational AI. The second essay examines the IT continuance through the theoretical lens of the expectation-confirmation model (ECM), incorportating cognitive and emotional satisfaction into the ECM framework. Empirical testing of the model suggests that it offers additional clarity on IT continuance phenomena and provides a significant improvement to the explanatory power of ECM in the context of an emerging technology. The third essay is one of the earliest efforts to conceptualize and test a theoretical model that considers emotional attachment in IT continuance behavior. This essay develops a novel model to investigate this phenomenon based on emotional attachment theory, and empirically validates the proposed model in the context of conversational artificial intelligence systems. While the existing theories of IT continuance focus …

Spiritually-Oriented Expressive Writing and Positive Psychological Outcomes Following a Natural Disaster (open access)

Spiritually-Oriented Expressive Writing and Positive Psychological Outcomes Following a Natural Disaster

Many religious/spiritual (R/S) individuals receive meaning from R/S and utilize R/S to help them cope with stressful life events. However, natural disasters can disrupt the R/S meaning-making process (e.g., positive R/S coping strategies) because natural disasters can elicit cognitive dissonance between one's core R/S beliefs and personal disaster experience. R/S individuals suffering from a disaster experience could benefit from interventions that allow them to process their R/S experiences. The purpose of this dissertation is to fill a gap in the literature by exploring the effectiveness of a spiritually-oriented expressive writing intervention on positive psychological outcomes (e.g., meaning in life, satisfaction with life) in 132 R/S individuals that have experienced a natural disaster (i.e., survivors of the 2016 Baton Rouge, Louisiana flood). Quantitative results indicated the spiritually-oriented intervention was effective in promoting increased meaning in life but not life satisfaction. Survivors with lower pre-intervention positive attitudes toward God evidenced the strongest positive impact on their meaning in life. Qualitative analyses, using the constant comparative method from Corbin and Strauss's grounded theory approach, revealed six themes in the experimental group's written responses: (a) R/S growth, (b) R/S struggle, (c) R/S cognitive dissonance, (d) R/S reappraisals, (e) R/S proximity-seeking, and (f) spiritual support …

Implications of Performance-Based Contracting on Logistics and Supply Chain Management: A Multi-Method Approach

Performance-based contracting (PBC) redefines the relationships between suppliers and buyers and differs from traditional contracting approaches with its reward/payment scheme, emphasis on the performance outcomes, increased supplier autonomy, and transfer of risk and responsibilities to suppliers. Given the 70% of life cycle costs of products/systems reside in sustainment, PBC has led to substantial improvements in availability, maintainability, reliability, and thus total cost of ownership of systems/products. Though PBC has changed the way of doing business and its presence has increased across multiple industry, private and public sectors, for profit and not-for-profit, its implications on various aspects of logistics and supply chain management have been understudied. It is important to explore and establish evidence regarding these implications through academic rigor. Therefore, this three-essay dissertation aims to give some insight regarding structural and behavioral implications of PBC using a multi-method approach. Specifically, it (1) explores the relationship between PBC and supply chain resilience (SCRES), (2) examines the supplier goal commitment (i.e., motivation) in PBC, (3) proposes a mathematical model to find optimal contract length, periodic contract price and investment that concurrently maximizing supplier profit and satisfying buyer requirements. This dissertation offers theoretical and managerial contributions as well.

The Applicability of the PICTS-SV in Offenders with Severe Substance Use Histories (open access)

The Applicability of the PICTS-SV in Offenders with Severe Substance Use Histories

Two important developments are addressed by this dissertation. First, the Psychological Inventory of Criminal Thinking Styles-Simplified Version (PICTS-SV) was examined in relation to the original PICTS. Second, the vulnerability of the PICTS-SV to intentional risk minimization (RM) was tested. Two separate studies recruited a total of 150 offenders from a court-mandated residential substance use treatment facility. As expected, Study I established the PICTS-SV's good concurrent validity with the PICTS, especially at the broad composite scale level. For Study II, criminal thinking failed to show the anticipated convergence with HCR-20 risk classifications or forensic correlates. Potential explanations, including a restricted range of risk levels in this sample, are discussed. As a particular strength, the findings highlight that the PICTS-SV, in contrast to many risk measures, displays robust resistance to RM distortion, although revisions to its Df-r validity scale are warranted. These results overall demonstrate strong evidence of the PICTS-SV's utility for assessing a dynamic criminogenic need to inform effective interventions and accurate risk determinations.

Toward an Experimental Analysis of a Competition between Dimensions of Cultural Consequences

The exponential growth of the human population has contributed to the overuse and degradation of common pool resources. Using science as a tool for informed policy-making can improve the management of our common pool resources. Understanding the conditions that influence groups of individuals to make ethical self-controlled choices may help solve problems related to the overuse and degradation of common pool resources. Ethical self-control involves the conflict of choice between one that will benefit the individual versus one that will benefit the group. The cumulative effect of many individuals behaving in an ethically self-controlled manner with common resource use may offset some of the harm posed by overuse of common pool resources. Metacontingency arrangements involving ethical self-control may provide some insight as to if and how groups may cooperate to manage a common pool resource. This manuscript proposes an experimental preparation and methodology to evaluate the effects of competing magnitudes of cultural consequences on culturants and their cumulative effect on common pool resources; and provides an analysis and discussion of five trends that might result from such a line of research.

The Embarrassment Paradox: Encouraging Compensatory Consumption in Morality-Laden Contexts (open access)

The Embarrassment Paradox: Encouraging Compensatory Consumption in Morality-Laden Contexts

This research introduces the unique context of immoral inaction—situations in which consumers have the opportunity to engage in virtuous behaviors but opt against doing so. Through five studies I demonstrate that in such contexts, embarrassment—a negatively valenced self-conscious moral emotion evoked by the perception that one's behavior is worthy of judgment by others—interacts with the use of approach-motivated coping strategies to lead consumers to engage in prosocial compensatory behaviors. Though extant literature suggests that marketers seeking to evoke prosocial behaviors should employ communications and promotions framed to elicit consumers' guilt, such studies are based in contexts whereby individuals feel guilty and/or embarrassed because of something they have done, not for something they did not do. This research suggests that that the condition of immoral inaction serves to evoke a contrasting psychological mechanism that reverses these findings, making embarrassment a more effective driver of desired outcomes when marketers seek to promote overcoming past inactions. These findings are discussed in light of their implications for research and application.

The Role of Combat Exposure, Moral Injury, and Trauma Symptoms in the Lives of Military Families

The current study used a sample of service members and veterans to explore the association of combat exposure and perceptions of the family system using a moderated mediation model. Combat veterans over the age of 18 with a family of creation (N = 154) completed an online survey through which they were administered a background information questionnaire, the Combat Experiences subscale of the Deployment Risk and Resilience Inventory – 2, the Moral Injury Events Scale, the PTSD Checklist for DSM-5, the Patient Health Questionnaire, the Beck Anxiety Inventory, the McMaster Family Assessment Device, and the Dyadic Adjustment Scale – Revised. Results of six moderated mediation analyses revealed that exposure to potentially morally injurious events (pMIEs) moderated the relationship between (1) combat exposure and couple relationship satisfaction and (2) combat exposure and family functioning, both via PTSS, anxious symptoms, and depressive symptoms. To our knowledge, the empirical models presented in this paper are the first to model the role of pMIEs in SMV literature, and provide a foundation for other models to emerge moving forward. Implications and limitations are discussed.

Extracting Dimensions of Interpersonal Interactions and Relationships

People interact with each other through natural language to express feelings, thoughts, intentions, instructions etc. These interactions as a result form relationships. Besides names of relationships like siblings, spouse, friends etc., a number of dimensions (e.g. cooperative vs. competitive, temporary vs. enduring, equal vs. hierarchical etc.) can also be used to capture the underlying properties of interpersonal interactions and relationships. More fine-grained descriptors (e.g. angry, rude, nice, supportive etc.) can also be used to indicate the reasons or social-acts behind the dimension cooperative vs. competitive. The way people interact with others may also tell us about their personal traits, which in turn may be indicative of their probable success in their future. The works presented in the dissertation involve creating corpora with fine-grained descriptors of interactions and relationships. We also described experiments and their results that indicated that the processes of identifying the dimensions can be automated.

Fanfare and Pastoral Topics in Mozart's Così fan tutte (open access)

Fanfare and Pastoral Topics in Mozart's Così fan tutte

This dissertation explores the use of topics for dramatic purposes in Mozart's Così fan tutte. The five analytical chapters are organized around a central question: how do pastoral and fanfare topics shape the plot of Così fan tutte? Chapter 2 highlights the role topics and tropes play in emplacing and nuancing emergent meaning in the Così fan tutte motto. Chapter 3 examines transformative topical tropes in "Ah guarda, sorella." Chapter 4 shows how the horn fifths and fanfare topics in "Per pietà, ben mio" frame Fiordiligi's choice: the Albanian or Guglielmo. Chapter 5 illustrates the relationship between fanfare topics and galant recitative schemas to articulate formal boundaries between accompanied recitatives and arias. The expectations of closure emplaced by the examples from Così fan tutte nuance a reading of "Hai già vinta la causa!" from Le nozze di Figaro. Chapter 6 discusses the role of recitative intrusions and their articulation of the Count's unrest in "Vedrò mentre io sospiro." Detailed analyses and close readings of the topics and tropes in this dissertation drawn from throughout Così fan tutte showcase Mozart's rich deployment of topics in varied musical and dramatic roles.
