Storytelling In Project Heart To Heart: A Means To Bridge Generational Gap In Post-1965 Filipino Immigrant Families, Juanita Toledo Santos Nacu Edd

Dissertations

As we share our experiences with others, we also explore its meaning to ourselves and to whomever it is being shared with. This is how stories are told. Most families usually develop a body of stories that is passed on from one generation to the next generation. These stories are used to preserve the family member's identity, history, and values. The stories touch not only our past experiences, but also influences our present and links it to the future. This study explored the Filipino American families' experiences of storytelling as a means of bridging together past, present, and future experiences …

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 …

Fractionally Sampled Decorrelating Detectors For Time-Varying Rayleigh Fading Cdma Channels, Huaping Liu

Dissertations

In this dissertation, we propose novel decorrelating multiuser detectors in DSCDMA time-varying frequency-nonselective and frequency-selective fading channels and analyze their performance. We address the common shortcomings of existing multiuser detectors in a mobile environment, such as detector complexity and the error floor. An analytical approach is employed almost exclusively and Monte Carlo simulation is used to confirm the theoretical results. Practical channel models, such as Jakes' and Markovian, are adopted in the numerical examples.

The proposed detectors are of the decorrelating type and utilize fractional sampling to simultaneously achieve two goals: (1) the novel realization of a decorrelator with lower …

Multi-Wavelength Pyrometric Systems For Emissivity-Independent Non-Contact Temperature Sensing, Michael B. Kaplinsky

Dissertations

A Multi-Wavelength Imaging Pyrometer (M-WIP) for real-time remote sensing of temperature profiles of targets with unknown emissivity was developed and demonstrated. To measure the spectral radiance of a target at several distinct wavelengths an M-WIP system was implemented based on an 320x122-element PtSi IR-CCD imager with an assembly of 7 narrow-band 1k filters in the range from 1790nm to 4536nm. A real-time algorithm for simultaneous estimation of the temperature and model parameters of the target emissivity from the least-squares fit of the theoretical model of 1k camera output signal to the experimental spectral measurements was developed and implemented. This rea1-time …

Motion Compensation And Very Low Bit Rate Video Coding, Shu Lin

Dissertations

Recently, many activities of the International Telecommunication Union (ITU) and the International Standard Organization (ISO) are leading to define new standards for very low bit-rate video coding, such as H.263 and MPEG-4 after successful applications of the international standards H.261 and MPEG-1/2 for video coding above 64kbps. However, at very low bit-rate the classic block matching based DCT video coding scheme suffers seriously from blocking artifacts which degrade the quality of reconstructed video frames considerably. To solve this problem, a new technique in which motion compensation is based on dense motion field is presented in this dissertation.

Four efficient new …

Sampling And Analysis Of Trace Level Volatile Organic Compounds From Air Via Membrane Permeation, Naihong Zhu

Dissertations

The objective of this study is to develop air sampling techniques using membrane permeation. Two novel techniques for sampling and analysis of trace level VOCs from air via membrane permeation are presented:

1. selective concentration of VOCs into a canister using a membrane permeator;
2. on-line membrane extraction for direct introduction of VOCs from air emissions into a gas chromatograph.

In the membrane permeator-canister sampling system (MPCS), the air sample containing trace level VOCs as well as some interferences such as moisture are passed through the membrane module. Polydimethyl siloxane membrane used in this research is highly permeable to organic compounds, but …

The Fatigue Problems Of Cracks Subjected To Obliquely Incident Stress Waves, I-Chung Weng

Dissertations

Catastrophic failure of aircraft and other structures are often caused by undetected cracks. Fracture mechanics has been developed to augment traditional static and fatigue design. In the static theory of fracture mechanics, extensive treatment has been given to the stress distribution around sharp cracks and notches under various loading conditions. Previous works on the problems of dynamic loadings are not accurate in dealing with singularities at high frequencies. The numerical solutions become unrealistic at high frequencies in many practical applications.

To address the need to obtain the stress intensity factor in high frequency dynamic loading situations, we studied the use …

Living With Changing Health: Perimenopause Among Chinese Women In Taiwan, Lee-Ing Tsao Dnsc, Mnsc, Rn

Dissertations

The purpose of this qualitative study was to generate theory about women's perimenopausal life experiences. Thirty-five Taiwanese women aged 40 to 59 who perceived themselves as perimenopausal and who were not using hormone therapy were interviewed. Data were generated from interviews which were conducted in Mandarin. Living with Changing Health was the core category for describing and guiding the process of perimenopause. During this process, Awareness was identified as the antecedent condition. Once the woman became aware, she would begin the process of living with her changing health. This process would be marked by action and interaction among the categories …

The Experiences Of Taiwanese Women Caregiving For Parents-In-Law, Shu-Yuan Chao Dnsc

Dissertations

Using grounded theory, a semi-structured in-depth interview was conducted to explore the experiences of Taiwanese women who were caregivers for their parents-in-law. Thirty-one Taiwanese women aged 23 to 58 participated in this study. Just Doing was identified as the core category to indicate the caregivers' striving process once they committed to their in-laws' care. Recognizing Duty, Experiencing Trials, and Responding to Caregiving were subcategories and reflected how a caregiver perceived her role, how she was affected by caregiving tasks, and what responses she had to the caregiving situation. The findings also suggested that caregiving behaviors were influenced by cultural expectations …

Determinants Of Health-Promoting Lifestyle Among Nurses In Taiwan, Chou Chuan-Chiang Yao Dnsc, Ms, Rn

Dissertations

This two-phase study was undertaken to: (1) determine the relationships of self-efficacy, perceived health status, perceived social support, age, marital status, education, work shift, work setting, and years employed as a registered nurse (RN) to the practice of a health-promoting lifestyle; (2) determine the combination of predictor variables explaining the variance in the practice of a health-promoting lifestyle; and (3) investigate other personal and environmental cues and characteristics related to health-promoting lifestyles among nurses (N = 218) in Taiwan. Findings of the quantitative approach in Phase One indicated that a health-promoting lifestyle was significantly related to self-efficacy, perceived health status, …

Data were analyzed for dimensions as well as conditions, context, action strategies, and consequences. The theory of cultural discovery described how nurses learn to see their Vietnamese clients, how they saw a common humanity with others, and how they learn to see health. Nurses who made …

Evaluation Of Environmental Characteristics Of Wtp Residuals For Disposal In Monofills, Ping Tian

Dissertations

Disposal of water treatment plant (WTP) have raised great concerns due to the stringent water quality standards and environmental regulations, and limited availability of land for ultimate disposal. The ultimate disposal of water treatment plant residuals by using monofill may be one of the most economical, and feasible options. Design and operation of such a monofill will be simple because of the uniformity of the characteristics of WTP residuals.

The objectives of this project were to determine the environmental characteristics of WTP residuals and to apply these characteristics for the design of monofills and development of the metal leaching model …

Empowering Teachers, Empowering Leadership: A Multisite Case Study Of School Restructuring And Accountability For Student Achievement, Sally Jean Bennett Edd

Dissertations

Accountability is the watchword of the 1990s, particularly in education. In exchange for greater flexibility and autonomy, schools have been asked to assume greater accountability for student outcomes. Implicit in this shift of authority and responsibility is the belief that changing the locus of control will result in changes in student achievement. Decentralizing accountability thus has multiple implications for the teaching and learning process, governance and decision making, and school site leadership. In 1993, San Diego City Schools adopted a student achievement accountability policy and initiated a demonstration program to develop an accountability system model for the district. This ethnographically-oriented …
