The Relationship Between Leadership/Followership In Staff Nurses And Employment Setting, Elaine S. Vandoren

Dissertations

This study tested the hypothesis that staff nurses in hospitals used different leadership and followership behaviors than staff nurses in home care settings. Leadership behaviors were measured using the Multifactor Leadership Questionnaire (Bass, 1995); followership was measured using Kelley’s Followership Style Questionnaire (1992). Three hospital and home care agencies belonging to a private nonprofit corporation in the Midwest provided data. A total of 136 surveys were used in data analysis; 57% of distributed surveys were returned.

Differences between the hospital and home care staff nurses were not found. Self-perception, difficulty in applying clinical behaviors to the MLQ, unknown aspects of …

Observing The Spirit Of Resilience: The Relationship Between Life Experiences And Success In Higher Education For African-American Students, Cheryl Getz Edd

Dissertations

Some African American students with challenging early life experiences appear vulnerable to failure in higher education. This vulnerability may be exacerbated when educators fail to recognize the relationship between the life experiences of African American students and their academic performance and college success. African American students are challenged further as they attempt to successfully adjust to collegiate environments which often do not validate them or their experiences. The primary purpose of this study is to investigate this challenge with selected African American students, to learn about how the life experiences of African American students can enhance their success in higher …

Enhanced Terahertz Pulse Generation And Detection Using Electric Field Singularities In Photo-Conducting Antennas, Yi Cai

Dissertations

In recent years, generation of ultra-short electromagnetic pulses with frequency components in the terahertz (THz) range has been achieved by various techniques. Among those different methods, photo-conducting antennas have proven to be the most efficient source of THz radiation. THz spectrometers utilizing such photo-conducting antennas as transmitters and receivers are meanwhile routinely used for spectroscopic studies in the frequency regime between 0.1 to 5THz, which can be covered by neither conventional optical nor microwave spectrometers. However, THz emission power from the existing photo-conducting antenna is not sufficient for many applications (such as electro-optic sampling for real time THz detection and …

Confronting First Nations Cultural Genocide: Showcasing Perspective Of Cree Elders For Identity And Leadership Renewal, Phyllis S.A. Cardinal Edd

Dissertations

The purpose of this study was to gain insight on the effects of cultural genocide through the lens of selected Cree elders in Alberta, Canada. The study enlisted the elders' perspective on the legacy of cultural genocide, and its residue. This process enabled the elders to offer views about Cree identity, and suggest a leadership perspective for continued cultural renewal. The study applied a Lockean theory to the attack on Natural Law to explain the genocide. The study also explained the way Locke's ideas may have contributed to the earlier federal policies that have subordinated the Cree, and to the …

A Theoretical Perspective Of Factors That Relate To The Functional Independence Of Mature Adults, Richard N. Ashden Edd,Dc

Dissertations

Limitations of policy makers and health care providers understanding about living conditions in later adulthood continually constrains mature adults from doing more for themselves, and society. These circumstances move society to devalue mature adults. Less valued mature adults tend to become even more dependent, that is, increasingly less willing to care for themselves, and less able to contribute to the social good. As a result, a vicious cycle was created, and it caused mature adults to live lower quality lives, and become increasingly dependent on others. To empower mature adults in later life, this study does the preliminary work to …

Teachers' Perspectives From Within A School Leadership Team: A Phenomenological Study, Sheridan L. Barker Edd

Dissertations

This qualitative study explored a different type of leadership by investigating leadership among peers in a California School Leadership Team (SLT). Using a phenomenological approach, the researcher asked ten teachers to describe their experience as members and as leaders in a schoolwide change team. The teachers characterized the SLT as: a positive force in the school, a vehicle for communication, and a support group. They described the experience as: eye opening, unique, challenging, and transforming. Five themes emerged as the essence of the experience: (a) the interdependent relationship among the team members; (b) the teachers' growing capacity to discern fine …

An Analysis Of Dialogue For Understanding Educators' Stress: Implications For Voice, Listening And Leadership, Joanna R. Doonan Edd

Dissertations

Research indicates that educator stress is a widespread phenomenon that not only impacts the educational community, but society at large. This being the case, there is an urgent need to consider this phenomenon within responsible school leadership. In particular, understanding what creates stress for educators, and learning more about leadership responses that would support educators under stress, are critical to more holistic school leadership, and for enabling teachers to envision a viable future for themselves. Thus, the purpose of this study is to examine how school principals and colleagues might respond to educators coping with professional stress, so that they …

Collaborative Teaching Practices For A New Century: A Descriptive Case Study Of Peer Coaching, Nance Maguire Edd

Dissertations

No longer is it appropriate for educators to come together as a group to "learn" a new skill and return to their classrooms to practice it in isolation. In the past, staff development programs have focused on development of a singular skill with teachers practicing it in isolation. The teaching and learning process can better be developed through collaboration. In order for this to happen effective teachers must be able to create effective interactive relationships with their peers. Hence, the practice and art of teaching ceases to be an individual enterprise; becoming instead a collaborative enterprise. Peer coaching is one …

Identification Of Core Multidisciplinary Competencies In An Integrated Public Health And Human Service System, Brian Winslow Thomas Moffitt Edd

Dissertations

In response to economic, legislative and social forces, public health and human service systems are becoming more integrative, requiring direct service practitioners to acquire new competencies to successfully perform in these new settings. In a review of the literature, competencies pertaining to team effectiveness, interprofessional collaboration and cross-functional knowledge and skills all appear to be relevant considerations. Moreover, an examination of competencies must consider individual, team and organizational dimensions in a context of health and welfare reform. However, the current literature is fragmented, limited in scope and empirically inconclusive. A descriptive, qualitative study was therefore warranted. The following research question …

Voices Against Discrimination And Exclusion: Latino School Leaders' Narratives For Change, Jaime J. Romo Edd

Dissertations

Many scholars, practitioners, and policy makers know very little about individual Latino administrators' cultural and professional experiences, responses to discrimination, and patterns or institutional conditions which relate to K-12 ethnic minority administrators' success. Moreover, many are also unaware that as ethnic diversity increases, the relative proportion of minority administrators, many of whom could be role models, shrinks. Once we can recognize this as seeds for inequity in society, we might be able to consider the ways in which our educational institution reinforces or counters societal inequities. By specifically exploring Latino administrators' experiences, because of the large Latino California presence, we …
