Increasing Nurse Leader Knowledge And Awareness Of Information And Communication Technologies, Cory Stephens

Walden Dissertations and Doctoral Studies

Due to the recent coronavirus disease (COVID-19) pandemic, rapid technological innovation and nursing practice transformation exposed a deepening divide in the knowledge and awareness of information and communication technologies (ICT) among nurses. This technological skills gap undermines the benefits of ICT to nursing practice such as increased nurse satisfaction, improved care quality, and reduced costs. Nurse leaders are positioned to promote the use of ICT among nurses but may suffer from the same knowledge deficit of ICT as their followers. Guided by Locsin’s technological competencies as caring in nursing theory, Staggers and Parks’ nurse-computer interaction framework, and Covell’s nursing intellectual …

Relationship In Alaska Native Corporations' Return On Equity From Sector, Gregory Stuckey

Walden Dissertations and Doctoral Studies

In 1999, Stephen Colt studied the 12 regional corporations formed under the Alaska Native Claims Settlement Act of 1971 (ANCSA). Colt reviewed the financial data from 1973 to 1993 and found the regional corporations lost approximately $380 million in business operations. However, the regional corporations increased their revenue from $714 million in 1993 to $8.575 billion in 2014. No further study of those subsequent 20 years has been conducted, so a data set to see if Colt’s conclusions hold was created. This multivariate correlational study tested two theories on the regional corporations: the theory of the economic efficiency of lump-sum …

School Counselors’ Lived Experiences Working With Northeastern Urban Minority High School Students, Lisette Ann Velez

Walden Dissertations and Doctoral Studies

Professional school counselors employed in low-income education communities have a large, diverse student population to service. Researchers have indicated that urban minority youth present more challenges in school than affluent students due to economic constraints and other related factors. School counseling members apply different skills or techniques mastered from their graduate and professional training regardless of existing inequalities. School counselors are ethically obligated to help minors attain academic success, social-emotional development, and postsecondary goals. The dearth of literature warrants more qualitative research studies to explore further the phenomenon of school counselors working in underprivileged neighborhoods. Husserl’s transcendental phenomenological framework provided …
