Historical Imperative: A Key To Korean Unification, Paul Hong

KAUPA Letters

This essay explores the theory of historical imperative as a foundational framework for understanding Korean unification. It argues that Korea's unique and continuous national identity, resilience against external invasions, and modern aspirations for unity make unification an inevitable outcome of historical forces. The discussion highlights Korea's 5,000-year historical narrative, incorporating both documented dynastic transitions and the foundational Dangun legend (2333 BCE). While the Dangun legend is regarded as mythology by many historians, it remains a vital cultural and national symbol, reflecting Korea’s deeply ingrained sense of identity and continuity. The essay examines the survival of Korea’s identity through foreign invasions …

Exploring And Implementing A Compassionate Social Service Ministry In Korean American Churches, Caleb Kim

KAUPA Letters

The purpose of this study is to explore the types and contents of church ministries provided by Korean American churches in the Chicagoland area. Using a conceptual content analysis, this study identified that most Korean American churches disproportionately offer an evangelical ministry to their fellow church members but overlook a compassionate social service ministry to their congregations, other ethnic minorities, the oppressed and unjust social issues. The most offered evangelical ministries are weekly worship services, evangelism, world mission, discipleship training, and Bible study. Only few churches provide financial aid support and pastoral care services to their church members and non-Korean …

Stress, Coping, And Psychological Growth In Personnel In A High Arctic Weather Station, Jelena Brcic, Patrick Nicoll, Peter Suedfeld, Phyllis Johnson, Lillian Shurgold

Journal of Human Performance in Extreme Environments

Ideas about positive change following a stressful experience have been of interest to researchers for some time (Antonovsky, 1987; Tedeschi & Calhoun, 1996). A few areas of study have been developed, some with a focus on successful coping such as research on resilience, sense of coherence and hardiness, stress inoculation, posttraumatic growth, and toughening (Tedeschi, Park, and Calhoun, 1998). Suedfeld (2001) has encouraged researchers to focus on the positive effects of work in extreme and unusual environments however, only a few have done so with astronauts, cosmonauts (Ihle et al., 2006: Suedfeld et al., 2012), and high-altitude mountaineers (Smith et …

Defining A Management Structure For University Space Analog Research Programs, Scott Van Hoy, Kristen Miller

Journal of Human Performance in Extreme Environments

To learn how humans can safely and effectively live on the surface of the moon or Mars, missions are conducted on Earth that simulate operations on the surface of other planetary bodies. These missions, called space analog missions, require substantial mission planning and organizational management to ensure safe and effective research and operations. The American Public University System’s Analog Research Group developed and tested management structures and philosophies that enable scalable, replicable, and safe analog missions. This fully online research endeavor’s management and internal organization offers a model that academic institutions and private industry can implement to contribute to space …

Exposure To Compound Climate Hazards Transmitted Via Global Agricultural Trade Networks, Patrick W. Keys, Elizabeth A. Barnes, Noah S. Diffenbaugh, Thomas Hertel, Uris L C Baldos, Johanna Hedlund

Department of Agricultural Economics Faculty Publications

Compound climate hazards, such as co-occurring temperature and precipitation extremes, substantially impact people and ecosystems. Internal climate variability combines with the forced global warming response to determine both the magnitude and spatial distribution of these events, and their consequences can propagate from one country to another via many pathways. We examine how exposure to compound climate hazards in one country is transmitted internationally via agricultural trade networks by analyzing a large ensemble of climate model simulations and comprehensive trade data of four crops (i.e. wheat, maize, rice and soya). Combinations of variability-driven climate patterns and existing global agricultural trade give …

Additionality Of Solar Tax Incentives Under Community Choice Aggregation In Ohio, Michael L. Smith, Carson Reeling, Michael D. Wilcox

Department of Agricultural Economics Faculty Publications

In the State of Ohio, the electric regulatory landscape permits local governments to become energy suppliers to residents and small businesses through community choice aggregation (CCA). Some CCAs provide enrollees 100% renewable electricity. Concurrently, the federal government offers an income tax credit (ITC) for the purchase of a solar array. With policy incentives, it is important to ensure they encourage behavior beyond the baseline scenario without the ITC. This is known as “additionality.” Renewable aggregation programs may crowd out the benefits of the ITC, violating additionality. This paper assesses additionality of the ITC in the context of Ohio’s CCA programs. …

Developing Students' Sociotechnical Thinking In The Humanities-Engineering Classroom: A Treatment Versus Control Study Using A Scenario-Based Assessment, Lori Czerwionka, Siddhant S. Joshi, Gabriel O. Rios-Rojas, Kirsten A. Davis

School of Engineering Education Faculty Publications

Background

Engineering problems are open-ended and complex, involving technical and social aspects, yet engineering education focuses on technical training and closed-ended problems. To prepare engineering students, curricula should foster sociotechnical thinking—the ability to consider the interplay of technical and social factors during problem solving. Although educational interventions in this area show promise, further insight into the benefits of interdisciplinary interventions is warranted, particularly with treatment and control group designs.

Purpose

We examine the effect of a Humanities-Informed Engineering Projects (HIEP) course on students' sociotechnical thinking development.

Method

We compared the sociotechnical thinking development of engineering students who took the HIEP …

Economic Analysis Of Global And Local Policies For Respecting Planetary Boundaries, Thomas Hertel

Department of Agricultural Economics Faculty Publications

In a series of highly cited papers over the period of 2009–2023, earth system scientists have identified a set of nine planetary boundaries that must not be breached if we wish to avoid catastrophic consequences for nature and humanity. These range from well-mixed, global boundaries, such as climate-altering atmospheric greenhouse gas concentrations, to localized limits on freshwater availability and reactive nitrogen entering the environment. Recent estimates suggest that six of the nine planetary boundaries have already been breached. The food system is a key driver of these exceedances and, therefore, must play a key role in any solutions. However, the …
