Miniature Embedded Module For Prognostic Health Monitoring (Phm) Of Electronic Systems, Liam Moore

Theses

Sensing systems for reliability prognostics are used extensively in life- and mission- critical electronics systems. They allow monitoring of reliability stresses in real time and scheduling of preventative maintenance before system failure. However, reliability prognostics systems are, in general, large and expensive and cannot be used in lower cost, small sized or portable products.

This thesis presents a sensing module for reliability prognostics which is only 1cm in volume and uses only commercial off-the-shelf components. In its 1cm package, the module combines all the necessary elements to act as an embedded prognostic sensor system for multi axial strain, vibration, humidity …

Selecting Ell Textbooks: A Content Analysis Of Language-Teaching Models, Jeffrey Labelle

College of Education Faculty Research and Publications

Many middle school teachers lack adequate criteria to critically select materials that represent a variety of L2 teaching models. This study analyzes the illustrated and written content of 33 ELL textbooks to determine the range of L2 teaching models represented. The researchers asked to what extent do middle school ELL texts depict frequency and variation of language-teaching models in illustrations and written texts. Using content analysis, they measured the range of depiction of the 4 language-teaching models and concluded that 4 of the 33 textbooks had considerable to extensive frequency and variation of L2 teaching models

Access To Adequate Outpatient Depression Care For Mothers In The Usa: A Nationally Representative Population-Based Study, Whitney P. Witt, Abiola O. Keller, Carrisa Gottlieb, Kristin Litzelman, John Hampton, Jonathan Maguire, Erika W. Hagen

College of Nursing Faculty Research and Publications

Maternal depression is often untreated, resulting in serious consequences for mothers and their children. Factors associated with receipt of adequate treatment for depression were examined in a population-based sample of 2,130 mothers in the USA with depression using data from the 1996–2005 Medical Expenditure Panel Survey. Chi-squared analyses were used to evaluate differences in sociodemographic and health characteristics by maternal depression treatment status (none, some, and adequate). Multivariate regression was used to model the odds of receiving some or adequate treatment, compared to none. Results indicated that only 34.8% of mothers in the USA with depression received adequate treatment. Mothers …

Psychometric Properties Of A Measure Of Acceptance Of Long-Standing Health Problems, Patricia Mcdonald, Jaclene Zauszniewski, Abir K. Bekhet

College of Nursing Faculty Research and Publications

Acceptance of chronic illness is important for health promotion and for improving the quality of life of elders with chronic conditions. Thus, a reliable and valid measure of acceptance is needed for this population. Currently available measures of acceptance do not focus specifically on accepting chronic conditions. This study of 176 elders with chronic conditions examined the psychometric properties of an adapted measure of acceptance—the Ideas About Long-Standing Health Problems (IALHP) questionnaire. Although the findings provided beginning evidence for internal reliability and construct validity to support its potential usefulness in elders, further scale development is recommended.

Psychometric Properties Of The Pressure To Move Scale In Relocated American Older Adults: Further Evaluation, Abir K. Bekhet, Jaclene Zauszniewski, Wagdy E. Nakhla

College of Nursing Faculty Research and Publications

The number of elders who relocate to retirement communities is increasing exponentially, and their ability to exercise free choice, personal control, and autonomy has been associated with relocation adjustment and positive outcomes in regard to physical, emotional, and social well-being. Although a measure of relocation controllability (the degree of personal control associated with the move) exists, there is limited evidence of its psychometric adequacy. This study tested the reliability and validity of the Pressure to Move Scale (PTMS). A convenience sample of 104 American elders who relocated to six Northeast Ohio retirement communities was recruited. Study participants completed the nine-item …

Measuring Use Of Resourcefulness Skills: Psychometric Testing Of A New Scale, Abir K. Bekhet

College of Nursing Faculty Research and Publications

Highly resourceful individuals have been found better able to meet life's challenges and to experience more positive health outcomes. Although psychometrically sound measures of resourcefulness exist and resourcefulness training trials show that the intervention increases adaptive functioning and enhances quality of life, there is no direct measure of intervention fidelity. This study examined the reliability and validity of an 8-item Resourcefulness Skills Scale (RSS), which measures the frequency with which intervention recipients use specific resourcefulness skills. The RSS was found to have acceptable internal consistency (� = .78), criterion-related validity (�'s = .50 and .52 with other resourcefulness scales), and …

Psychology Faculty Research and Publications

Reviews the book, The dark side of creativity by David H. Cropley, Arthur J. Cropley, James C. Kaufman, and Mark A. Runco (see record 2010-16278-000). Theory and research on creativity clearly address how breakthrough ideas are formed and what happens to them next, but the present state of creativity research needs a few breakthrough ideas of its own. The Dark Side of Creativity , edited by David Cropley, Arthur Cropley, James Kaufman, and mark Runco, has hit that target. It also resonates with contemporary concerns about creativity and technology. There is a long-standing ethic in engineering that a technology itself …

The Influence Of Contraception On Abortion Among Women Of Reproductive Age In The United States, Richard J. Fehring

College of Nursing Faculty Research and Publications

There is a common notion that contraception is necessary for women (and couples) to avoid unwanted pregnancies and abortions. The thesis of this paper is that contraception actually will lead to more (not less) abortions. On the other hand, the use of natural family planning (NFP) and the acceptance of fertility lend itself to the openness to life. The specific purpose of the paper is to describe the influence of contraceptive use and NFP on the likelihood of having an abortion among United States (US) women of reproductive age as found in Cycle 7 of the National Survey of Family …

The Effects Of Positive Cognitions On The Relationship Between Alienation And Resourcefulness In Nursing Students In Egypt, Abir K. Bekhet, Mervat Elguenidi, Jaclene A. Zauszniewski

College of Nursing Faculty Research and Publications

Alienation is a subjective state, a feeling of being a stranger, as if one were not one's normal self. It is also a sense of homelessness; a feeling of uneasiness or discomfort, which signifies the person's exclusion from social or cultural participation. Alienation can adversely affect healthy functioning of nursing students. Nursing students are the adolescents of today and the nurses of tomorrow who will deal with human behavior, and their psychological well-being will be important in managing their clients’ conditions. Healthy nursing students are likely to become healthy nurses who can then model and promote healthy lifestyles for their …

Alteration Of Hydrogen Bonding In The Vicinity Of Histidine 48 Disrupts Millisecond Motions In Rnase A, Nicolet Doucet, Gennady Khirich, Evgenii L. Kovrigin, J. Patrick Loria

Chemistry Faculty Research and Publications

The motion of amino acid residues on the millisecond (ms) time scale is involved in the tight regulation of catalytic function in numerous enzyme systems. Using a combination of mutational, enzymological, and relaxation-compensated ¹⁵N Carr−Purcell−Meiboom−Gill (CPMG) methods, we have previously established the conformational significance of the distant His48 residue and the neighboring loop 1 in RNase A function. These studies suggested that RNase A relies on an intricate network of hydrogen bonding interactions involved in propagating functionally relevant, long-range ms motions to the catalytic site of the enzyme. To further investigate the dynamic importance of this H-bonding network, this …

Direct Patterning Of A Cyclotriveratrylene Derivative For Directed Self-Assembly Of C60, Zachary R. Osner, Dorjderem Nyamjav, Richard C. Holz, Daniel P. Becker

Chemistry Faculty Research and Publications

A novel apex-modified cyclotriveratrylene (CTV) derivative with an attached thiolane-containing lipoic acid linker was directly patterned onto gold substrates via dip-pen nanolithography (DPN). The addition of a dithiolane-containing linker to the apex of CTV provides a molecule that can adhere to a gold surface with its bowl-shaped cavity directed away from the surface, thereby providing a surface-bound CTV host that can be used for the directed assembly of guest molecules. Subsequent exposure of these CTV microarrays to C₆₀ in toluene resulted in the directed assembly of predesigned, spatially controlled, high-density microarrays of C₆₀. The molecular recognition capabilities …

Recent Advances In The Synthetic And Mechanistic Aspects Of The Ruthenium-Catalyzed Carbon-Heteroatom Bond Forming Reactions Of Alkenes And Alkynes, Chae S. Yi

Chemistry Faculty Research and Publications

The group’s recent advances in catalytic carbon-to-heteroatom bond forming reactions of alkenes and alkynes are described. For the C–O bond formation reaction, a well-defined bifunctional ruthenium-amido catalyst has been successfully employed for the conjugate addition of alcohols to acrylic compounds. The ruthenium-hydride complex (PCy₃)₂(CO)RuHCl was found to be a highly effective catalyst for the regioselective alkyne-to-carboxylic acid coupling reaction in yielding synthetically useful enol ester products. Cationic ruthenium-hydride catalyst generated in-situ from (PCy₃)₂(CO)RuHCl/HBF₄·OEt₂ was successfully utilized for both the hydroamination and related C–N bond forming reactions of alkenes. For …
