Asian American Females In Educational Leadership In K-12 Public Schools, Dina Castillo Pacis Edd

Dissertations

The research on educational leadership has largely excluded the perspectives of women and minorities. As school age populations become increasingly diverse, the need for principals from diverse backgrounds also increases. However, the research data shows that females and ethnic minorities are underrepresented in educational leadership positions. In an effort to address the lack of minority females in educational leadership, particularly Asian American females, more research needs to be conducted on their perceived barriers to upward mobility, as well as their perceptions of educational leadership. Only when the voices of Asian American female minority administrators are heard, will they be better …

Navigating The Change Of Life: The Menopausal Transition Of Thai Immigrant Women, Bulaporn Natipagon-Shah Phd, Msn, Rn

Dissertations

Given that women continue to live more than three decades after menopause and their health and well-being in later life are determined by quality of health during the menopausal transition, menopause has become an important issue in the healthcare arena. The growing number of immigrant women in the United States signifies a need for healthcare providers to develop cultural knowledge and sensitivity toward each immigrant group regarding the issue of menopause. The purpose of this qualitative study was to build a substantive grounded theory of the experiences of menopausal transition among Thai immigrant women in the United States. Data collection …

From Presence To “E-Presence” In Online Nursing Education, Lisa M. Kaiser Phd, Msn, Bsn, Rn

Dissertations

Online web-based course offerings are now common in many institutions of higher education In response to the current and severe nursing shortage, estimated to represent a 20% vacancy rate by the year 2015, (Tarkin, 2003) many more universities have created online nursing courses for registered nurses wishing to continue their education in nursing. The National League for Nursing (NLN) set research priorities that urged exploration of the impact that technology has on the content and nature of teaching and learning in nursing education (1999). Using a series of separate synchronous, online focus groups and 1:1 interviews with nurse educator experts …

How Leaders Use The Construct Of Culture To Influence Change Resistance: A Study Of A Planned Change Initiative In A Combined Government And Military Organization, Derek R. Noether Edd

Dissertations

The construct of organizational culture has been used to interpret various aspects of organizational life, including organizational leadership and organizational change. The literature indicates that leaders can influence organizational change by attending to and modifying an organization's cultural dimensions. Much of this literature, however, is theoretical and speculative, and the empirical work that does exist has focused mostly on business. The purpose of this case study was to develop an understanding of how leaders in a combined government and military organization used the notion of culture during a two-and-a-half year planned change initiative. The study explored the strategies and mental …

Cognitive Orthotics For Students With Cognitive Disabilities, James V. Yanna

Collaboration Through Partnerships: A Review Of Six Michigan Communities, Cheryl Kay Sibilsky-Soule

Dissertations

The federal government supports the use of collaborative service planning for many federally funded programs. While there are anecdotal studies supporting community collaboration, its use has not been adequately evaluated. This study provides exploratory information regarding the relationship between successful collaboration and outcomes for children and families.

Data were collected from six Michigan communities using a survey tool sent to all members of the six community Family Coordinating Councils. The tool was designed to measure eight factors seen in successful collaboration. The respondents evaluated their own collaborative council on these eight factors.

Three of the communities were thought to be …

Bufadienolides In The Chemical Defenses Of The Toads, Bufo Americanus And Bufo Fowleri, Catherine E. Merovich

Dissertations

I investigated the steroidal chemical defenses (bufadienolides) of Bufo americanus and Bufo fowleri. By the nature of their complex, biphasic life cycles, toads, like other amphibians are important components of aquatic and terrestrial habitats and are prey to numerous invertebrates and vertebrates. Bufadienolides are presumed to be important anti-predatory compounds although much of their chemical ecology is poorly understood. I investigated (1) ontogenetic variation in bufadienolides, (2) bufadienolides from adult parotoid secretion, (3) effectiveness of bufadienolides against a terrestrial predator, and (4) effectiveness of bufadienolides against an aquatic predator. I hypothesized that B. americanuswould have a more extensive …

Factors Affecting Treatment Program Development In A Mental Health Facility Serving Prisoners, Ruby Miranda Meriweather

Dissertations

There is a paucity of literature on how treatment programs for mentally ill prisoners are developed. Federal mandates require that services to mentally ill prisoners be comparable to what is offered in the community. Planners, therefore, must find ways to provide treatment programs that produce that outcome.

This research identified the most important factors that affect treatment program development and implementation to aid planners in designing treatment programs for mentally ill prisoners. This qualitative study, based on grounded theory, used a structured interview with 61 mental health staff (psychiatrists, nurses, psychologists, social workers, and activity therapists) across three categories (Administrative, …

The Italian Homiliary: Texts And Contexts, Michael Thomas Martin

Dissertations

For the Carolingians, preaching was the best manner in which to teach good, Christian behavior orally to the largely illiterate masses. Studying early medieval sermon collections then can provide historians with a great amount of information on, for example, the intended audience and current moral instruction, who wrote the sermons, and the intended impact of the reform requirements. Too often however these early collections are grouped into a rather generalized classification of being little more than an exposition of Scripture composed with little or no originality. Some scholars claim we have no evidence for sermons produced for popular preaching prior …

Reconciling Temporalities: A Substantive Explanation Of The Origins Of Difficulty In The Nurse Patient Encounter, Marilyn Theresa Macdonald Phd

Dissertations

Nurses describe patients as difficult on a regular basis. Nursing research to date has assumed the existence of this phenomenon. Most studies have listed descriptors of the difficult patient and offered interventions for nurses to use to alter patient behavior. Locating of difficulty within the individual and failure to consider the context of the nurse patient encounter is problematic. The practice of locating difficulty in the individual absolves organizations and society of responsibility to work to change factors that contribute to the construction of difficulty. The purpose of this research was to move beyond a focus on the patient as …

The analysis will also identify whether there are any individual and institutional characteristics that are significant predictors for determining curriculum. This study's targeted participants are a random sample of 110 program directors working in institutions that have a Physical Education Teacher Education program.

Differences were found to exist in directors' perceptions regarding curriculum. Descriptive statistics and ANOVA analysis demonstrated the impact …

Hope—Heartbeat Of Adult Education: A Phenomenological Inquiry, Phillip L. Moulden

Dissertations

This phenomenological study of the phenomenon—hope identified two essential meaning structures (“change” and “human agency”) in the experiences communicated by the Adult Educators interviewed. It was also discovered that hope is an energy that interacts with Affective, Relative (Re-lay-tive), and Cognitive energies in the lives of the research participants. Understanding how “change” and “human agency” can be aligned with these A.R.C. energies holds implications for further research and the practice of Adult Education.

Characteristics Of Nanocomposites And Semiconductor Heterostructure Wafers Using Thz Spectroscopy, Hakan Altan

Dissertations

All optical, THz-Time Domain Spectroscopic (THz-TDS) methods were employed towards determining the electrical characteristics of Single Walled Carbon Nanotubes, Ion Implanted Si nanoclusters and Si_1-xGe_x HFO₂, SiO₂ on p-type Si wafers.

For the nanoscale composite materials, Visible Pump/THz Probe spectroscopy measurements were performed after observing that the samples were not sensitive to the THz radiation alone. The results suggest that the photoexcited nanotubes exhibit localized transport due to Lorentz-type photo-induced localized states from 0.2 to 0.7THz. The THz transmission is modeled through the photoexcited layer with an effective dielectric constant described by a Drude …

Turbo Space-Time Coding For Mimo Systems : Designs And Analyses, Hangjun Chen

Dissertations

Multiple input multiple output (MIMO) systems can provide high diversity, high data rate or a mix of both, for wireless communications. This dissertation combines both modes and suggests analyses and techniques that advance the state of the art of MIMO systems. Specifically, this dissertation studies turbo space-time coding schemes for MIMO systems.

Before the designs of turbo space-time codes are presented, a fundamental tool to analyze and design turbo coding schemes, the extrinsic information transfer (EXIT) chart method, is extended from the binary/nonbinary code case to coded modulation case. This extension prepares the convergence analysis for turbo space-time code.

Turbo …

The experiment tested the impact of these structures on groups negotiating the requirements for an emergency response information system. The results reported here show that these …

Congestion Control In Resilient Packet Ring Networks, Alharbi Fahd

Dissertations

The Resilient Packet Ring (RPR) is a new metro technology; RPR shares SONET's ability in providing fast recovery from link and node failures as well as inherits the cost and simplicity of Ethernet. RPR, like SONET/SDH, is a ring based architecture consisting of two optical rotating rings (uni-directional). In RPR, packets are removed from the ring at the destination so that different segments of the ring can be used at the same time for different flows; as a result, the spatial reuse feature is achieved. Enabling the spatial reuse feature introduces the challenge of guaranteeing fairness among the nodes sharing …

Image Data Hiding, Zhicheng Ni

Dissertations

Image data hiding represents a class of processes used to embed data into cover images.

Robustness is one of the basic requirements for image data hiding. In the first part of this dissertation, 2D and 3D interleaving techniques associated with error-correction-code (ECC) are proposed to significantly improve the robustness of hidden data against burst errors.

In most cases, the cover image cannot be inverted back to the original image after the hidden data are retrieved. In this dissertation, one novel reversible (lossless) data hiding technique is then introduced. This technique is based on the histogram modification, which can embed a …

Computational Studies Of Viscoelastic Multiphase Flows, Shriram B. Pillapakkam

Dissertations

A finite element code based on the level set method is developed for performing two and three dimensional direct numerical simulations (DNS) of viscoelastic two-phase flow problems. The Oldroyd-B constitutive equation is used to model the viscoelastic liquid. The code is used to study transient and steady state shapes of Newtonian and viscoelastic drops in simple shear and buoyancy driven flows. The roles of the governing dimensionless parameters: Capillary number (Ca), Deborah Number (De) and the polymer concentration parameter c, in determining deformation of drops and bubbles, are also analyzed.

The numerical code permits us to vary Ca, De and …

Live, Virtual, And Constructive Environments For Performance Support, John Michael Lacontora

Dissertations

As military systems become more complex, the operation and support of these systems becomes intrinsically more difficult. The U.S. Army's current procurement process relies on industry to provide embedded training and performance support tools for the systems they produce. These tools are relatively new and in the early stages of development. As yet, they have failed to meet the needs of the technicians that are required to support these complex systems. Current efforts to provide enabling technologies that enhance the capabilities of automotive maintenance technicians are concentrated in three professional communities. First is the Performance Improvement community where work is …

Scattering Matrix Analysis Of Photonic Crystals, Valeriy Lukyanov

Dissertations

Using a scattering matrix approach we analyze and study the scattering and transmission of waves through a two-dimensional photonic crystal which consists of a periodic array of parallel rods with circular cross sections. Without making any assumptions about normal incidence, single mode propagation, and sufficient inter-scatter separation in the direction of propagation, we show how to compute the transmission and reflection coefficients of these periodic structures. The method is based on the computation of a generalized scattering matrix for one column of the periodic structure.

We also develop an analytical method to analyze and to study the scattering and transmission …

Qos Constrained Cellular Ad Hoc Augmented Networks, Chi-Tung Chen

Dissertations

In this dissertation, based on different design criteria, three novel quality of service (QoS) constrained cellular ad hoc augmented network (CAHAN) architectures are proposed for next generation wireless networks. The CAHAN architectures have a hybrid architecture, in which each MT of CDMA cellular networks has ad hoc communication capability. The CAHAN architectures are an evolutionary approach to conventional cellular networks. The proposed architectures have good system scalability and high system reliability.

The first proposed architecture is the QoS constrained minimum-power cellular ad hoc augmented network architecture (QCMP CAHAN). The QCMP CAHAN can find the optimal minimum-power routes under the QoS …

Seeking Life Balance: The Perceptions Of Health Of Cambodian Women In Resettlement, Olivia Catolico Phd, Msn

Dissertations

This grounded theory study was an inquiry into the perceptions of health of Cambodian women in resettlement and the conditions that influenced their perceptions. Few studies of Cambodian women who escaped political conflict exist. Cambodian women were among the waves of Southeast Asian refugees who have resettled in the United States. The sequelae of significant life trauma upon the health of Cambodian women in resettlement have received little attention in the nursing literature. There is less information about their perceptions of health in resettlement as their beliefs about health and illness causation contrast with those of Western health care providers. …

The Heavenly Sanctuary/Temple Motif In The Hebrew Bible : Function And Relationship To The Earthly Counterparts, Elias Brasil De Souza

Dissertations

The present dissertation investigates the function of the heavenly sanctuary/temple and its relationship to the earthly counterparts, as reflected in forty-three passages of Hebrew Bible.

Following an introductory chapter, the second chapter of this dissertation is devoted to a survey of the heavenly sanctuary/temple motif in the ANE literature, as represented by Sumerian, Akkadian, Hittite, Ugaritic, and Egyptian texts. The investigation of these texts reveals that the heavenly sanctuary/temple motif was part of the worldview of the ANE, where the heavenly sanctuary was not only assumed as existing in heaven, but also as functioning in close relationship to the earthly …
