When Access Fails Quietly : A Privilege Maturity and Control Drift Framework for Governance Risk in Open-Source ERP Systems

2025-08-22T07:18:51+00:00

Open-source ERP systems such as ERPNext provide flexibility for resource-constrained enterprises but often lack mature governance controls. This paper introduces a driftaware framework for access governance, centered on three novel constructs: the Privilege Maturity Index (PMI), Control Drift Taxonomy (CDT), and Access Governance Risk Score (AGRS). Validated through a longitudinal ERPNext case study in a Gulfbased firm, the model reveals how silent erosion of access discipline undermines governance integrity. Findings emphasize that systemic risks stem less from external breaches and more from organizational drift. In addition to highlighting an original framework, we show how the model naturally aligns with emerging guidance such as NIST CSF 2.0 and zero-trust architectures, ensuring both originality and applicability in modern governance contexts.

2025-09-13T08:58:39+00:00

The Kanuri language, spoken by over 5 million people in West Africa, faces significant challenges in digital communication due to its non-standard characters and diacritics. This study designs, evaluates, and statistically validates a linguistically optimized Kanuri keyboard layout that outperforms QWERTY by 27.7 % in speed and 33.3 % in accuracy. Applying Fitts’ Law and character frequency analysis, the proposed layout prioritizes high-frequency characters (e.g., a, n, ə) on the home row and integrates dead keys for diacritics. Usability testing with 20 native speakers demonstrated a 27.7% improvement in typing speed (23.3 WPM vs. 18.1 WPM on QWERTY) and a 33.3% reduction in error rates. Iterative refinements based on user feedback resolved key accessibility issues, such as relocating the g key and optimizing modifier layers. The findings highlight the importance of language-specific keyboard designs in promoting digital inclusion and preserving linguistic diversity. This research contributes to human-computer interaction (HCI) by providing a replicable framework for marginalized languages with non-standard orthographies.

A Genetic Algorithm-Driven Personalized Genome Mutation Pathway Predictor for Early Diagnosis of Rare Polygenic Disorders

2025-09-17T09:32:19+00:00

Accurate prediction of rare polygenic disorders remains a significant chal-lenge in precision medicine, primarily due to the fact that they involve a complicated genetic architecture and current computational models are re-stricted. Traditional polygenic risk scores (PRS) have additive assumptions and finite cross-population validity and hence are not appropriate for rare disorders. In this study, a novel GA-based approach is presented that models individualized forward mutational routes, enabling early identification of risk genomic configurations. Each GA chromosome represents a binary vector of rare variants from whole-genome sequencing data, and evolutionary processes are guided by a composite fitness function. The function integrates pathogenicity scores, disease associations, and population rarity to yield biologically relevant simulations. Using 1000 Genomes Project data, we simulate 500 mutational trajectories in 500 different individuals. Results determine an average 27.2% increase in pathogenicity and 38.4% increase in harmful variants, with more than 60% convergence to known disease profiles in European and South Asian genomes. Approximately 24% of simulated genomes per individual exceed high-risk thresholds, outperforming PRS in identifying non-additive and epistatic effects. This GA strategy offers a dynamic, ancestry-aware approach to predicting rare disease risk, broadening the scope of predictive genomics and enabling earlier, more specific clinical interventions.

Personality Prediction System via Curriculum Vitae (CV) Analysis Using Natural Language Processing (NLP) and Logistic Regression.

2025-01-10T09:41:19+00:00

When it comes to the study of humans, adjudicating one’s personality is important as it acts as a window to deciphering the individual’s mindset. The personality is a vital part of an individual when he or she works for a complex organization. There are several ways to determine an individual’s personality but the most sought after and direct method is through a simple quiz. The questions in the quiz are framed in a way that they take values with reference to the big five personality model and aid the developer in framing a personality report of the individual in question. When I take a look at the current process of hiring and selection that various organizations make use of, the employers often pick out CVs in a manual way which is monotonous, time-consuming, and consumes a lot of human resources. Our approach is rendering an automated model that motorizes the eligibility check and aptitude evaluation of an applicant in the selection process to target the drawbacks of the traditional recruitment system, a web application that analyzes both the personality and an individual’s CV has been curate. This model employs a machine learning algorithm namely “Logistic Regression” which helps to choose fair decisions to recruit a suitable candidate, and “Natural Language Processing (NLP)” uses techniques with the help of Natural Language Toolkit (NLTK) libraries to process and categorize the data. Also, the use of graphs to analyze a candidate's success makes it easier to assess his or her personality and aids in proper CV analysis. As a result, the framework lends a hand in the recruitment process, allowing the candidate's CV to be shortlisted and a reasonable decision to be reached.

Fuzzy Logic Based Personalised Diet Recommendation Engine for Dietary Prevention and Control of Diabetics

2025-03-05T13:12:15+00:00

Dietary management is a cornerstone in the prevention and treatment of Type 2 diabetes mellitus. Despite advancements in understanding dietary approaches, many patients rely on generalized advice rather than individualized plans. The affordability and accessibility of nutritious food remain significant barriers in low- and middle-income settings. Additionally, there is limited integration of technology-based tools into routine care to assist healthcare providers in delivering personalized dietary recommendations. The aim of this research is to develop a personalized food mapping system that aligns dietary recommendations with the health conditions and preferences of diabetes patients. The system derives its framework from the Nigerian food composition table thus providing culturally appropriate advice to its users. Analysing nutritional values together with local food glycemic indexes enables users to identify more suitable dietary choices which both match their nutritional requirements and food tastes. An individualised dietary system helps users maintain their planned meals more easily and these strategies work to preserve blood sugar levels. By providing recommendations that are truly individualized, it can help people better manage their blood sugar and overall health, which is essential for preventing serious long-term complications. Beyond diabetes, this personalized diet system could serve as a model for managing other health conditions. It offers a more effective way to give dietary advice, improving patient outcomes and making healthcare more efficient. Ultimately, this approach could make it easier for healthcare providers and patients alike to manage diet-related health challenges in a way that feels more personalized and adaptable.

2025-06-10T12:16:48+00:00

The opacity of black-box models presents a significant obstacle to their acceptance in the medical field. To improve their adoption, it is crucial to identify the stakeholders who need explanations of these models and to develop effective methods for providing these explanations. This paper aims to identify the key actors/stakeholders in the medical field who require explanations of black-box models to enhance their adoption. Through a comprehensive literature review, we identify physicians, patients, regulatory bodies, ethicists, and legal professionals etc. as the primary actors with information needs regarding the workings and rationale of black-box models. Physicians require explanations to validate predictions against their clinical expertise, while patients seek transparency to understand the basis of recommendations. Regulatory bodies focus on compliance and ethical considerations, while ethicists and legal professionals evaluate fairness and accountability. By providing tailored explanations to these actors, trust can be fostered, informed decision-making facilitated, ethical concerns addressed, regulatory compliance ensured, and effective communication established. This research highlights the information needs of various stakeholders, proposes two frameworks—Human-Centered XAI Design and a workflow for black-box model research—and emphasizes the importance of explanations in enhancing the adoption of black-box models in the medical field.

2024-12-08T08:52:50+00:00

The process of selecting colleges and securing admissions is influenced by numerous elements, particularly academic performance, behavioral tendencies, and equity considerations. Academic metrics such as high school grades and standardized exam results often form the cornerstone of admission criteria. However, behavioral factors, including decision-making styles, personal motivations, and self-image, play an equally critical role in shaping students' application choices. For instance, while some students may aspire to enroll in elite universities, others, constrained by financial limitations or self-imposed doubts, might opt for less competitive institutions. Social influences, access to advisory resources like school counselors, and awareness of the admissions process further shape students' choices and behaviors. Students from underserved or marginalized communities often face additional hurdles, leading them to prioritize institutions based on proximity, affordability, or program flexibility that aligns with their unique needs. This paper explores agent-based modeling techniques adopted by international universities to study secondary education pathways and student behaviors in the context of admissions. By examining these models, the research highlights how they simulate complex decision-making processes and systemic interactions to foster equitable practices in university admissions. Emphasizing behavioral dimensions, these models underscore the importance of creating fairer systems that address the diverse needs and aspirations of students while promoting inclusivity and justice in higher education.
