Two Engineering Organizational Development (EOD) classes were analyzed: one with 60% international students (60IS) and another with 100% international students (100IS). In 100IS, around half of the students relied heavily on ChatGPT, showing little interest in traditional learning, while 60IS retained more conventional study patterns. The research also evaluated two Graduate Academic Research (GAR) courses before and after a redesign aimed at reducing plagiarism and improving learning outcomes. In redesigned GAR, students performed better on smaller, skills-based assignments incorporating ChatGPT. However, patterns of plagiarism in major assignments persisted across both GAR courses. The findings highlight the ongoing challenge of AI misuse in education despite course redesigns and suggest a need for continued efforts to integrate AI tools responsibly in academic settings.

Through analyzing actual classroom dynamics within engineering education, this paper examines the nature of AI’s role, particularly concerning critical thinking and academic integrity. In courses such as Engineering Organizational Development (EOD) and Graduate Academic Research (GAR), the pervasive availability of ChatGPT has led some students to rely heavily on AI-generated content, disengaging from core learning processes. Despite course redesign efforts to curb plagiarism and foster meaningful engagement, many students remain dependent on AI, revealing a potential new "addiction" to AI-generated responses. This trend underscores the need for educational institutions to develop balanced policies and operational methodologies that incorporate AI as a complementary tool rather than a replacement for essential academic skills. Ultimately, this study highlights the complexities of AI's integration in education and the importance of a foundational understanding of theory and practice when teaching students to value the learning journey as they navigate an increasingly AI-driven academic environment.

A proposed foundational framework highlights four critical factors: 1) the application of force, 2) the taking of resources, 3) knowledge processing, and 4) direction setting. This approach enables a comprehensive global analysis of the ethical dimensions in software development and use, contrasting voluntary exchanges with those compelled by thieving. Focusing on a case study of a large manufacturer, these foundational factors are applied to both individual and organizational behavior. The core challenge identified is the temptation for individuals and organizations to exploit the ease of force-driven resource acquisition rather than adhering to foundational ethical guidelines. Traditional reliance on published codes of ethics for moral reassurance is found to be inadequate, particularly within complex organizational structures where key decisions are pre-determined before employees are tasked with their execution. The foundational approach reveals the susceptibility of organizations to distorted and high-ignorance-content interpretations of law and ethics. This article outlines potential solutions to enhance ethical adherence, emphasizing the need for robust ethical guidelines that permeate all levels of decision-making within organizations.

Utilizing a simple multi-generational model of comet fragmentation, it analyzes the planet's interaction with the comet's fragment chain and simulates probability distributions for both chain crossing and fragment capture. This model offers insights complementary to impact theories that seek to explain the Younger Dryas boundary. Moreover, the potential presence of cometary material in Earth's orbit due to crossing a comet's fragment chain could profoundly influence climate patterns, with far-reaching implications for global agriculture and food production.

It is shown that a systematic stratification of biological knowledge provides new insights into understanding of the material and energy flow processes. The model allows for an objective mapping of the knowledge-based genetic, epigenetic, and supragenetic spaces of different material scales that can also be approximated as an organizing principle.

A simple, general, multi-generational model of comet fragmentation and fragment separation is developed, yielding the fragment distribution for each generation of the comet's fragment chain. The fragment chain is used in analysis of the planet's chain crossing and fragment capture. Simulating the chain crossing and fragment capture, the probability distributions for the chain crossing and fragment capture are calculated. The average probability for the planet crossing the fragment chain of a small, long period comet is 0.43 × 10 - 3 per perihelion passage. The average probability for the planet crossing the fragment chain of a small, short period comet is 1.01 × 10 - 3 per perihelion passage. For both, the average probability of fragment capture in chain crossing is 5.84 × 10 - 2 per crossing. The probabilities calculated for the planet crossing a fragment chain and capturing fragments are higher than the planet-comet collision probability of the order of 10 - 9 per perihelion passage for both the short period and long period comets, thus making chain crossing and fragment capture more probable planetary events.

The GSM, applied through Python coding, predicts a planet's average number of fragment crossings and the probability of capture. Using OCM we find that upon crossing, a significant fraction of fragments escape, a notable percentage gets captured and forms a near-spherical shell around the planet, and a smaller number impacts the planet. Applying GSM to the fragment chain of a 100-km-diameter comet's fully fragmented chain, the planet crosses an average of about 32 thousand fragments with an average capture probability of 5.33 × 10-2 per crossing per perihelion passage. OCM results indicate that 58.8% of crossed fragments escape, 36.7% are captured in orbit around the planet, and 4.5% impact the planet. The distinctive feature of OCM calculations lies in the nearspherical planetary shell formed by captured fragments. The planetary shell dynamics is analyzed in relation to the planet's Roche limit. The capture simulation with fluid fragments moving at the planet speed demonstrates that 4.2% are fully within, 23.7% are partially within, and 72.1% are outside the Roche limit.

Despite its presence in all activities of production and exchange of goods and services, the ethical underpinnings of economics lack clarity. The purpose of this paper is to shed light on ethical dimensions woven into the structural features of economics. This would allow a deeper understanding of ethical considerations that shape economics, thereby enhancing our understanding of ethical implications in societal decision-making regarding resource allocations to serve the needs of all.

The best evidence comes from instances where actions considered stupid at an individual level are embraced and perpetuated societally without any recognition of their inherent stupidity. This article explores two prominent examples of such phenomena, shedding light on the complexities of human cognition and societal behavior.

One such aspect originates at the earth's two versions. Humankind has a good understanding of one version and little if any of the second. Such lack of knowledge would adversely affect the development and maintenance of human wholeness. This proposal considers a workshop at the 2020 Learning and Teaching Forum to address this knowledge deficiency in University of Dayton's community through participative knowledge processing and systems thinking. Starting at the very beginning, the "whole person" is a suitcase word, 1 indicating that by itself it carries little meaning and any higher level of meaning can only come from knowledge placed into the suitcase. For example one can add meaning through 3H model. This model brings in head, heart, and hands into the suitcase of the whole person. But then, head, heart, and hands are also suitcase words. A higher level of meaning is achieved by seeing "head" as search for meaning, search for purpose, search for values and other similarly important things. Heart would encompass things like "love, inner peace, resilience, and connection." Along the same line of reasoning we can fill the suitcase of "hands" with behavioral aspects that relate to "outward expression of spiritual needs, such as life choices, behavior toward others, rituals, and practices." 2 Note that each of these levels of meaning enhances our view of wholeness but at the same time introduces more suitcase words whose meaning we must address by adding new knowledge into their suitcases.

It is shown that this integrated, foundational model improves the understanding of human choices in application of force and management of resources. The model simplifies and streamlines the complexities and deficiencies faced in current theories. The case of the civil war is treated, and the findings are applied to violence reduction, identifying factors that influence individual orientation toward application of force and development of advantageous resource positions.

Deficient societal structures often originate in ignored and misunderstood foundations in both the present and the past. Every society, in its transitions, loses the memory of part of its previous knowledge. The loss of historical memory is a serious deficiency that currently permeates every society and prevents a deeper understanding of current behaviors that have their origin in the knowledge of the past. From this perspective, the currently accepted view of the education system lacks a foundational anchor. Lack of awareness of foundational knowledge engenders a malfunctioning education system and a misunderstood psychology of human individual, adversely affecting societal existence. This article focuses on the societal foundation as a composite of knowledge and ignorance, demonstrating its management crucial for societal wellbeing and existence. I...

Amplified Milankovitch theory and canopied earth theory of glacial-interglacial cycles provide conflicting signals, one seeing the current interglacial lengthened by human-induced climate change giving the human societies ample time to prepare for the next glacial and the other seeing the arrival of the next glacial to be independent of human activities and thus posing a supreme risk to unprepared human societies. Foundational analysis indicates little difference between the ancient and modern humans reacting to glacial-interglacial cycles. Both, preoccupied with daily requirements of life fail to prepare to address their knowledge deficiencies of global physical conditions and thus expose individuals and societies ...

The EPM approximation introduces the concept of an effective size for the rigid molecular units and considerably simplifies the calculations of librationlibration and libration-translation force constants. The proposed model has been applied successfully to the lattice-dynamics calculations of polyethylene. The unknown forceconstant parameters are determined from fitting the measurements of long-wavelength frequencies and the elastic constants. The model imposes restrictions on the relative values of normal-mode vibrations which make the present assignments of v5(0) and v7{0) frequencies unacceptable. The present calculations of polyethylene dispersion curves are 1 1 1 the only calculations which exhibit the two features of symmetry about the 00 2,~2 0, and-0 points in the Brillouin zone as well as showing three acoustic dispersion branches. These features are not observed in any of the previous calculations of polyethylene dispersion curves.
