Leadership In Quality Improvement In Academic Children’S Hospitals, Tiffany Enriquez

Walden Dissertations and Doctoral Studies

To orient children’s academic leaders to basic competency in quality improvement (QI) practices, academic children’s hospitals must overcome leadership diversity deficits and prepare for QI practice readiness. Leadership is a key factor in enhancing patients’ care outcomes, though practice models do not allow for organizational advancements. The distributed leadership (DL) theory on leadership applies in contexts where the leadership role in QI is not solely centralized to a single individual but is decentralized and spread to include all parties involved. This paper sought to determine the effects of leadership on QI in children’s hospitals and further establish the best leadership …

Complaints Against Police Officers, Allegation Dispositions, And Suspension Length In New York City, Nathan Michael Hunter

Walden Dissertations and Doctoral Studies

Extant literature on police officer misconduct has shown that it was possible to identify problem officers in a proactive manner. Yet serious misconduct incidents continued to occur that strain the relationship between the public and police, including the government serving both entities. The New York Police Department was the largest city police force in the United States, with approximately 33,475 full-time sworn officers, and in 2023, New York City (NYC) paid $298 million in settlements related to claims against police officers. Considering this, further research into police officer misconduct was warranted to fill a gap in the literature that can …

Cyberterrorists use cyberspace to communicate their threats and conduct their actions to intimidate their political, religious, or ideological control. The literature reviewed on cyberterrorism and international law has been limited and continues to develop as cyberterrorists develop their skills and capabilities to conduct cyberattacks. A gap exists in the literature on how nation-states respond to a cyberattack, cyber warfare, or cyberterrorism under international laws and policies. The problem is that international laws are being outpaced by the development of new technology, which cybercriminals and cyberterrorists can circumvent in order to escape punishment for a cyberattack. The purpose of this basic …
