Evolving Leadership And Increased Wisdom – Understanding Ethical Leadership, Tangela Rutledge, Cam Caldwell

The Journal of Values-Based Leadership

Laying the foundation for understanding ethical leadership, we begin this paper by identifying a framework for understanding the leader’s roles based upon five dimensions for understanding leadership’s duties and responsibilities. We present a model for ethical decision making that addresses the complex factors of ethical decision-making based upon a virtuous continuum. We then review five levels of leadership identified by Jim Collins (2001) in his research about leaders – identifying the special significance of Level 5 leaders who enabled their companies to evolve from “Good” to “Great.” We describe the characteristics of leaders in each of Collins’ five leadership levels …

Crafting Ethical Problem-Solving Cultures: A Leader’S Role In Complex Adaptive Systems, Elizabeth A. Luckman

The Journal of Values-Based Leadership

In today’s complex and interconnected world, leaders play a critical role in fostering ethical problem-solving cultures within organizations. To enable leaders to succeed in this evolving landscape, this paper advocates for a necessary paradigm shift: a transition in mental models about how organizations function. Historically, organizations have been viewed as mechanistic systems, but there is a substantial opportunity to improve our work by viewing organizations as complex adaptive systems. This shift alters fundamental assumptions about organizational operations and redefines leadership as the creation of conditions for effective and ethical problem-solving. In this paper, I examine the changing mental models that …

Earthjustice: The Role Of The African Regional Human Rights System In Containing Climate Change, Bright Nkrumah, Ebenezer Durojaye, Maria Usang Assim

Journal of African Policy Studies

At the turn of the millennium, the landscape of Africa has been punctuated by intense weather conditions. With a disproportionate percentage of the continent’s population bearing the brunt of climate-induced heatwaves, deluges, and drought, it is expected that this phenomenon will spur regional climate litigation. The essay argues that although there is an evolution of climate cases submitted at the national level, this development has not evolved to the African regional human rights system. The lack of cases at the regional level beckons one to explore why (potential)victims are unable or unwilling to explore these mechanisms given their role in …

Technology And The Sustainable Implementation Of The African Continental Free Trade Area (Afcfta) Through Women’S Integration, Philip Ademola Olayoku

Journal of African Policy Studies

The desire for economic prosperity on the African continent led to the African Continental Free Trade Area (AfCFTA), in line with the vision of the Organisation of African Unity (OAU), when it proposed the creation of an African Economic Community (AEC) by 2028. However, sustainable economic development will remain a mirage without inclusivity where no one is left behind, in line with the African Union’s Agenda 2063. This study explores the challenge of restricting women to economic margins in trade agreements under the AfCFTA and how this would undermine its implementation. It subsequently contends that women are integral to Africa’s …

Aldh7a1 Gene And Its Related Pyridoxine-Dependent Epilepsy, Flavia M.C. La Mendola, Tiziana Timpanaro, Daniela Caruso, Maria Teresa Garozzo, Santiago Presti, Catia Romano, Elena R. Praticò, Antonio Zanghì, Raffaele Falsaperla

Journal of Pediatric Neurology

Despite being classically reported as caused by mutations in solute carriers genes (SLC2A1), it has been recently shown that also mutations in ALDH7A1 can cause pyridoxine-dependent epilepsy (PDE). ALDH7A1 is a gene encoding for the antiquitin, an enzyme that catalyzes the nicotinamide adenine dinucleotide-dependent dehydrogenation of L-α-aminoadipic semialdehyde/L-Δ1-piperideine 6-carboxylate. It is a highly treatable disorder, but nevertheless it is still not certain when to consider this diagnosis and how to test for it. It is possible to identify a classical form and an atypical one of PDE associated with more than 70 mutations of ALDH7A1 gene. The typical form is …

Explicit Bounds And Parallel Algorithms For Counting Multiply Gleeful Numbers, Sara Moore, Jonathan P. Sorenson

Computer Science and Software Engineering

Let k ≥ 1 be an integer. A positive integer n is k-\textit{gleeful} if n can be represented as the sum of kth powers of consecutive primes. For example, 35=2³+3³ is a 3-gleeful number, and 195=5²+7²+11² is 2-gleeful. In this paper, we present some new results on k-gleeful numbers for k > 1.

First, we extend previous analytical work. For given values of x and k, we give explicit upper and lower bounds on the number of k-gleeful representations of integers n ≤ x.

Second, we describe and analyze two new, efficient parallel …

The Criminal Record As A Death Sentence: Unmasking The Ignored Realities Of Formerly Incarcerated University Graduates On Professional Licencing Challenges, Mbongiseni Mdakane, Bongani Innocent Nkambule, Sindile Amina Ngubane

Journal of Prison Education Research

Recently it is increasingly common practice for universities and professional registration councils to probe into applicants’ criminal records as a precondition for admission. Using social constructionism, this qualitative study explored the experiences of six formerly incarcerated individuals previously sentenced to life imprisonment, who hold professional university degrees in Law, Education, Psychology and Social Work and investigated whether having a criminal record had any bearing when applying for professional registration. The results indicate that due to the perceived stigma of, and discrimination against a criminal record, there exist varying degrees of criminal record disclosure ranging from partial, to full and non-disclosure. …

Atom-Chip Compatible Optical Lattice, Robert Leonard, Spencer E. Olson

Space Dynamics Laboratory Publications

A lattice beam configuration which results in an isotropic 3D trap near the surface of an atom chip is described. The lattice is formed near the surface of a reflectively coated atom chip, where three incident beams and three reflected beams intersect. The coherent interference of these six beams form a phase-stable optical lattice which extends to the surface of the atom chip. The lattice is experimentally realized and the trap frequency is measured. Degenerate Raman sideband cooling is performed in the optical lattice, cooling 80 million atoms to 1.1 μK.

Ti-Ulpcs: Threshold-Issuance - Un-Linkable Policy Compliant Signatures, Kiran Deep Ghosh

Master’s Dissertations

Digital signatures, as a strong cryptographic primitive, ensure the authenticity and integrity of signed messages. On one hand, no one can forge a verifiable signature without knowing the secret key, on the other hand, any correctly formed signature is always verifiable under the public key of the signer. Besides signing digital data, they serve as foundational components in more advanced cryptographic systems, including blind signatures, group signatures, direct anonymous attestation, e-cash, e-voting protocols, adaptive oblivious transfer, anonymous credential schemes, Policy-Compliant Signatures, etc. Policy-Compliant Signatures (PCS) enable the enforcement of joint policies between the signer and the verifier. A signature of …

Zkipv: Zero-Knowledge Proofs For Image Provenance Verification, Bibek Ghosh

Master’s Dissertations

Recent advances in generative AI have significantly improved the ability to create photorealistic synthetic images, including so-called deepfakes, raising concerns about misinformation and the erosion of trust in digital media. Ensuring the integrity and authenticity of images, especially in sensitive domains like journalism, is thus increasingly critical. Existing solutions such as the C2PA (Content Provenance and Authenticity) framework provide origin verification through cameragenerated digital signatures, but fail to account for image modifications that invalidate these signatures. To address this limitation, we propose a zero-knowledge approach to verifiable image editing that preserves both integrity and privacy. This system, ZK-IPV, introduces a …
