Item Restricted The Moderating Role of Organizational Environment Effectiveness on the Relationship Between Saudi Arabian Nurse Managers' Delegation Abilities and Leadership Practices(Zarqa University, 2025-05) Faranti, Amani Mohammed Omer; Alhusban, Raya YousefBackground: Effective leadership and delegation are critical competencies for nurse managers, particularly in healthcare systems characterized by hierarchical structures and resource limitations. In Saudi Arabia, limited evidence exists on how organizational environment factors influence the relationship between nurse managers’ delegation abilities and leadership practices. Aim: This study aims to examine the moderating role of organizational environment effectiveness on the relationship between delegation abilities and leadership practices among nurse managers in Saudi Arabian governmental hospitals. Methods: A descriptive cross-sectional correlational study was conducted with a convenience sample of 183 nurse managers from three governmental hospitals in Saudi Arabia. Data were collected using three validated instruments: the Delegation of Authority Scale (DoAS), the Leadership Practices Inventory (LPI), and the Organizational Environment Assessment (OEA). Descriptive statistics, multiple linear regression, and moderation analysis were performed using SPSS version 26. Results: The mean delegation score was low (M = 1.74, SD = 0.18), with 78.7% of participants classified in the low delegation category. Leadership practices were moderate (M = 127.98, SD = 12.55), with “Modeling the Way” scoring highest (M = 40.23, SD = 5.08). Organizational environment effectiveness was perceived as poor (M = 10.54, SD = 2.13). Moderation analysis revealed that the organizational environment significantly influenced the delegation–leadership relationship (interaction term B = -1.170, p = 0.006), weakening the effect of delegation in unsupportive settings. The number of units managed negatively predicted leadership (B = -1.965, p = 0.040). Conclusion: Organizational environment plays a critical moderating role in the effectiveness of delegation on leadership practices. Targeted interventions to enhance organizational support, resource availability, and manageable workloads are essential to foster effective nursing leadership.5 0Item Restricted A Graph-Based Formal Access Control Model to Support Positive & Negative Permissions, Exceptions, Redundancy & Conflict Detection, Permission to Delegate, Delegation, Separation of Duties (SoD), and SoD Exceptions & Violation Detection(University of Idaho, 2024-12-30) Alkhorem, Azan Hamad; De Leon, Daniel ConteAccess control policies models provide a better approach to control users actives regarding allowing or denying such action to user or group within the resources. This mechanism allowed us to verify the grant or the denial of access. Within the access control hierarchy structure, there are more features that must be supported with different permissions on non-hierarchy and hierarchy structure. In this study we developed a methodology that supports the enhancement of positive policy represented by (YES) and adds negative policy represented by (NO). Moreover, we include supporting both types of permission to delegate and both types of delegation. Although, we implement supporting an exception policies approach for both types of stander policies positive and negative. Furthermore, we developed a method to adopt two different types of Separation of Duties (SoD). This includes redundancy, conflict detection, valid polices request of SoD, violation, and non-violation polices request between each type itself and between the first type against the second concept of SoD rules as well as vice versa. In addition, we validate another technique that these two different types of SoD do not violate both types of stander policies concept. Finally, we examine both types of stander policies concept never violate both types of SoD rules in the hierarchy manner. These challenges have been successfully verified on the hierarchy policy model (HPol). These features give the HPol model more advantages supporting complex polices on non-hierarchy and hierarchy structure.26 0
