The Impact And Evaluation Of Forgiveness Education With Early Adolescents, Hillary Karyn Elda Hilbert

Honors Program Theses

Research has shown that forgiveness is a complex process and is vital to one’s well-being (Coyle & Enright, 1997; Enright, 1991; Freedman, 2007). There have been several research studies conducted with various populations (Freedman & Enright, 1996; Coyle & Enright, 1997; Gambaro, Enright, Baskin, & Klatt, 2008; Waltman et al., 2009) who have experienced deep, personal, and unfair hurts. Forgiveness has been found to be healing and beneficial to one’s overall psychological well-being in these studies. It is often assumed that forgiveness is a natural process, but this is not necessarily true. Forgiveness is something that can be taught (Freedman, …

Honors Program Theses

The 1928 language revolution in Turkey involved the change of the Turkish writing script from the Arabic to the Latin alphabet, as well as the elimination of Arabic and Persian loan words and associated imported grammar. In this study, we assessed the impact this language revolution had on Turkish identity by examining it through the lens of Ottoman and Turkish literature and poetry. To achieve this, we compared literary and poetic themes from before and after the language revolution; we also studied the activity of prolific writers from before and after the transition to determine what effect, if any, the …

Prolonged Fatigue In Ukraine And The United States: Prevalence And Risk Factors, Fred Friedberg, Nathan L. Tintle, Jake Clark, Evelyn Bromet

Faculty Work Comprehensive List

Background: Prolonged, severe, unalleviated fatigue may be disabling whether it occurs on its own or in conjunction with medical or psychiatric conditions. This paper compares the prevalence and correlates of prolonged fatigue in general population samples in Ukraine versus the US. Methods: Population surveys were conducted in 2002 in both Ukraine (Ukraine World Mental Health [WMH] Survey) and the US (National Comorbidity Survey-Replication; NCS-R). Both surveys administered the Composite International Diagnostic Interview (CIDI 3.0), which contained modules assessing: neurasthenia (prolonged fatigue); mood, anxiety, and alcohol/drug use disorders; chronic medical conditions; and demographic characteristics.

The ’73 Graft: Punishment, Political Economy, And The Genealogy Of Morals, Bernard E. Harcourt

Faculty Scholarship

In this essay, I explore the place of a genealogy of morals within the context of a history of political economy. More specifically, I investigate the types of moralization – of criminals and delinquents, of the disorderly, but also of political economic systems, of workers and managers, of rules and rule-breaking – that are necessary and integral to making a population accept new styles of political and economic governance, especially the punitive institutions that accompany modern political economies in the contemporary period.

The marriage of political economy and a genealogy of morals: this essay explores how the moralization of certain …

Modeling Human Gaming Playing Behavior And Reward/Penalty Mechanism Using Discrete Event Simulation (Des), Christina M. Frederick, Michael Fitzgerald, Dahai Liu, Yolanda Ortiz, Christopher Via, Shawn Doherty, Jason P. Kring

Publications

Humans are remarkably complex and unpredictable; however, while predicting human behavior can be problematic, there are methods such as modeling and simulation that can be used to predict probable futures of human decisions. The present study analyzes the possibility of replacing human subjects with data resulting from pure models. Decisions made by college students in a multi-level mystery-solving game under 3 different gaming conditions are compared with the data collected from a predictive sequential Markov-Decision Process model. In addition, differences in participants’ data influenced by the three different conditions (additive, subtractive, control) were analyzed. The test results strongly suggest that …

The Damaging Effects Of Climate Change Denial, Richard Snow, Mary Snow

Publications

It has been said that those who are denying climate change are like the ostrich that sticks her head in the sand, but is this analogy entirely accurate? By hiding from the threat, does the ostrich make the threat go away, mitigate it, or make it greater? Probably, she does not. However, denying the existence of climate change does exacerbate the problem and exponentially so. As the renowned British economist Nicholas Stern reports, the longer world leaders wait to take serious action to curtail climate change, the more it will cost. As the Chair of the Grantham Research Institute on …

Causes And Trends In Maintenance-Related Accidents In Faa-Certified Single Engine Piston Aircraft, Douglas Boyd, A. Stolzer

Publications

The accident rate for general aviation remains high. While most general aviation accident studies have been pilot-focused, there is little research on the involvement of aircraft maintenance errors. We undertook a study to answer this question.

The Microsoft Access database was queried for accidents occurring between 1989 and 2013 involving single engine piston airplanes operating under 14CFR Part 91. Pearson Chi-Square, Fisher’s Exact Test, and Poisson probability were used in statistical analyses.

The rate of maintenance-related general aviation accidents was 4.3 per million flight hours for the 1989–1993 period and remained unchanged for the most recent period (2009–2013). Maintenance errors …

The Model Of Network Carriers' Strategic Decision Making With Low-Cost Carrier Entry, Tamilla Curtis, Dawna L. Rhoades

Publications

"After deregulation in the United States in 1978, airlines faced intense competition on previously regulated routes. The proponents of deregulation stated that equilibrium in the industry would be achieved by providing lower fares and improved service (Daraban and Fournier, 2008). While this became true to some extent, the airline network in the U.S. was dominated by the hub-and-spoke system and concentrated in the hands of few large airlines. The emergence of the Low-Cost Carrier (LCC) model, which originated in the U.S. through Southwest Airlines in the early 1970s, became an instrument to drive the airlines towards a competitive equilibrium. The …

Black Male "Buoyant Believers" In Engineering And Engineering-Related Fields, Leroy L. Long Iii, Joseph Allen Kitchen, Trevion S. Henderson

Publications

Strategies for improving student success are particularly important in high-demand fields like science, technology, engineering, and math (STEM). As the U.S. experiences a decline in skilled STEM workers and a growing number of racial/ethnic minorities, it is critical that more attention be paid to the college success of underrepresented populations majoring in STEM. While some strategies for increasing STEM student success have focused on social-psychological factors such as academic self-efficacy and resilience, little attention has been given to these factors among specific minority groups in STEM such as Black men. To extend the current literature, interviews with 27 Black male …

For the purpose of this discussion, the non-traditional student is defined as one with a delayed entry to college after high school completion, who may bring time-management conflicts due to work and family commitments, and who may have a variety of transcripted and non-transcripted credits to consider for transfer or advanced standing.

Comparison Of Lock-In And Pulse-Phase Thermography For Defect Characterization In Frp Composites Applied To Concrete, Jeff Brown, Sai Harsha Chittineni

Publications

Thermal imaging is a well-established technique for the non-destructive evaluation of FRP composites applied to reinforced concrete. Defect characterization using IR thermography, however, remains a topic of on-going research, and there are currently no universally accepted standards for data collection or interpretation. This research involved large scale thermography inspection of two FRP strengthened bridge girders that were removed from service after approximately 10 years of service in a potentially corrosive marine environment. Trial inspections were performed on test areas where defects could be identified using sounding methods. Two procedures showed the most promise for identifying and characterizing defects: sinusoidal (lock-in …

New Environmental Demands And The Future Of The Helsinki−Tallinn Freight Route, Olli-Pekka Hilmola, Harri Lorentz, Dawna L. Rhoades

Publications

The environmental friendliness of short sea shipping has been justified in Europe by the ensuing lower congestion at hinterlands and unneeded large-scale infrastructure investments on roads and railways. However, the attractiveness of short sea shipping is about to change. This is because of increasing environmental regulations (International Maritime Organization (IMO) sulfur regulation in the Baltic Sea and planned CO2 emissions trading) and increased world market oil prices. In this research, we analyze this potential change using data envelopment analysis on the existing transportation chain alternatives in the Helsinki (Finland)−Tallinn (Estonia) short sea route (chains using either roro, ropax or container …

Observational Evidence Of Quasi-27-Day Oscillation Propagating From The Lower Atmosphere To The Mesosphere Over 20° N, K.M. Huang, Alan Liu, S.D. Zhang, F. Yi, C.M. Huang

Publications

By using meteor radar, radiosonde and satellite observations over 20° N and NCEP/NCAR reanalysis data during 81 days from 22 December 2004 to 12 March 2005, a quasi-27-day oscillation propagating from the troposphere to the mesosphere is reported. A pronounced 27-day periodicity is observed in the raw zonal wind from meteor radar. Spectral analysis shows that the oscillation also occurs in the meridional wind and temperature and propagates westward with wavenumber s = 1; thus the oscillation is of Rossby wave type. The oscillation attains a large amplitude of about 12 m s−1 in the eastward wind shear region of …
