Using the Multi-Tiered System of Supports (MTSS) framework, the project developed and disseminated an interactive, evidence-based video …

Ai At Work, Algorithmic Bosses, And The Ambivalence Of Automation, Antonio Aloisi, Valerio De Stefano

All Papers

This chapter revisits a foundational question (“what do bosses do?”) to explore how artificial intelligence (AI) is reshaping power dynamics in the workplace. Far from neutral tools of optimisation, algorithmic systems increasingly amplify managerial prerogatives, embedding them into automated processes that are difficult to scrutinise or contest. These developments give rise to a paradox: managers and workers are simultaneously augmented and disempowered, caught in systems that intensify control while eroding autonomy. Drawing on legal, organisational, and regulatory perspectives, we argue that existing safeguards, ranging from data protection rights to information and consultation, are ill-equipped to confront this shift. The chapter …

The Lived Experiences Of Clinically Licensed Counselors During Covid-19, Deirdre F. Haynes

Walden Dissertations and Doctoral Studies

The COVID-19 pandemic has proven to be an equal opportunity crisis. There is substantial research to better understand how individuals have reacted to crisis experiences like the COVID-19 pandemic. However, little is known about the lived experiences of clinically licensed counselors during COVID-19. This gap in the literature is important because the increase in the number of individuals seeking counseling to deal with their fears and concerns related to the COVID-19 pandemic may have put a strain on counselors that were also experiencing the effects of the COVID-19 pandemic. The purpose of this interpretative phenomenological analysis was to bridge the …

The Impact Of Tuition Assistance On Employee Retention: Cybersecurity Employee Perceptions Of National Security Agency’S College Tuition Assistance Program, Marta I. Benitez-Guzman

Walden Dissertations and Doctoral Studies

U.S. employers spend considerable sums on employee skill development, including investments in college tuition assistance programs (CTAP). Based on a review of recent literature, measuring employer return on investment can be difficult. The literature contained varying results on the effectiveness of employer-provided incentives on retention decisions and provided insufficient empirical or evaluative data on employee perceptions and the influence on retention. The purpose of this qualitative evaluative case study was to examine how cybersecurity employees at the National Security Agency (NSA) who participated in CTAP (2019–2023) perceived the program's effect on their career development and retention decisions. The theoretical framework …

Counselors’ Competency Development In Suicidal Ideation Assessments Of Black American Adolescents, Salita Mcclelland Wynn

Walden Dissertations and Doctoral Studies

Black American adolescents have increased rates of suicidal ideation above what is noted in the general U.S. youth and adolescent population. An in-depth literature supports the notion that many counselors and mental health clinicians, post-graduation from their training programs, feel ill-equipped to assess suicidal ideation in Black American adolescents. The purpose of this qualitative, hermeneutic phenomenological study was to examine the lived experiences and competence of counselors who have clinical experience working with Black American adolescents who have suicidal ideation. Prior to the inception of this research, no other documented study addressed counselor competence with assessing suicidal ideation in Black …

Orbital Maneuvers And Interplanetary Trajectory Design Via Reinforcement Learning, Roberto Cuéllar Rangel

Doctoral Dissertations and Master's Theses

This dissertation investigates the application of reinforcement learning (RL) to the design and optimization of low-thrust spacecraft trajectories, with an emphasis on autonomy, adaptability, and robustness in the presence of system uncertainties and unmodeled perturbations. Classical approaches to low-thrust trajectory design are predominantly grounded in optimal control theory, which relies on the availability of precise dynamical models and often requires problem-specific reformulation and solver tuning. While optimal control methods offer high accuracy under deterministic conditions, their sensitivity to stochastic disturbances and computational limitations in highly nonlinear or uncertain environments pose significant challenges for future autonomous space missions.

To address these …

Rational Tactical Nuclear First Use In Asymmetric Dyads And The States' Calculus Of Costs In An Era Of Interdependence : A Game-Theoretical Approach, Chi Cheong Chiu

Lingnan Theses (MPhil & PhD)

Classical nuclear deterrence theory suggests that nuclear powers could be tempted to strike first in asymmetric dyads (dyads in which only one side is a nuclear power). However, in the Ukraine war, a nuclear-armed Russia has not deployed tactical nuclear weapons on the battlefield, even at times when its military struggles on the ground with unfavorable balance. Why has Russia not used its nuclear weapons, especially after repeated threats of using them? What conditions make it rational for states to cross the nuclear threshold in asymmetric dyads? What discourages them from using nuclear weapons while possessing nuclear monopoly?

Cybersecurity: Digital Stewardship In A Violent World, Rocky K. C. Chang

University Faculty Publications and Creative Works

This paper defines cybersecurity based on the principle of biblical stewardship. The focus of this principle is God, not the technologies, who is the creator and owner of cyberspace and everything in it. Humankind is called by God to steward them by protecting the digital property of our neighbors in cyberspace from malicious attacks. In the context of cybersecurity, a neighbor can be any individual cyber user, practitioner, educator, organization, tech company, or even hacker. However, as argued from the perspectives of human sin and human finitude, the defending stewards can never win over evil in this spiritual battle. Instead, …

Rethinking Cognitive Load: Validating A Two-Factor Framework Of Cognitive Load Across Problem-Solving Formats With Differing Levels Of Guidance, Camden Noelle Patterson

Electronic Theses and Dissertations Archive

Cognitive Load Theory has recently been revised to exclude germane load as a distinct construct, prompting a re-evaluation of intrinsic and extraneous load measures. This study tested the psychometric validity and predictive utility of a two-factor cognitive load model during algebra problem-solving with worked examples or independent practice. Confirmatory and exploratory factor analyses supported the structural validity of two established instruments (Leppink et al., 2013; Krieglstein et al., 2023) when germane load items were removed. Regression analyses indicated no significant differences in cognitive load or learning outcomes between instructional groups. However, pre-test performance strongly predicted post-test scores, and intrinsic and …

A Place For Ancient Philosophy In Axial Age Historiography, John R. Shook

Comparative Philosophy

Long-standing debates over historiographical approaches to the Axial Age have distracted the history of philosophy from its own disciplined inquiry into the breadth and depth of ancient thought beyond the Greeks. The philosopher Karl Jaspers offered a vista for seeing commonalities among ancient innovations and discerning continuities along history to modern times. That dual agenda divided Axial historiography with the question of whether axiality reflects creativities of ancient systems or have modern reflections created images of axiality. A singular chronology for humanity encourages a mode of philosophical history open to providential designs, epochal turns, spiritual evolutions, psychological leaps, or cognitive …

Moral And Ethical Nature In Confucian Liang-Zhi And Islamic Fitra: Comparative Perspectives On Innate Morality, Yanrong Shi

Comparative Philosophy

This article offers a comparative philosophical analysis of Confucian liang-zhi (innate moral knowledge) and Islamic fitra(primordial nature), focusing on their accounts of innate morality and moral epistemology. Drawing on classical Confucian sources—especially the praxis-oriented interpretation of Wang Yangming—and foundational Islamic texts and commentary, the study demonstrates that both traditions posit an inborn moral faculty grounding ethical universality and responsibility. Wang Yangming’s liang-zhi is conceived as an innate moral principle that, under the imperative of zhi (to actualize or extend), is continually activated through moral practice. In parallel, fitra is understood as a God-given orientation to truth, cultivated and safeguarded through …

The Conventional Emptiness Of Human Beings: Reviewing Archer’S Theory Of Agency Through Nagarjuna’S Looking Glass, Federico Podestà

Comparative Philosophy

Margaret Archer is probably the critical realist who has most significantly affected the debate around the relationship between social structure and agency. In the volume, Being Human: The Problem of Agency, she aims to better define what is meant by the properties and causal powers of agency itself, i.e., self-consciousness and reflexivity. In this paper, this theoretical attempt is reviewed through the critical standpoint of Nagarjuna. Nagarjuna’s philosophy appears to be a particularly compelling tool for criticizing Archer’s theory. Claiming the emptiness of everything, the founder of the Buddhist Madhyamaka school provides a critical perspective for revising the distinctiveness of …
