Marital and Social Changes in the Lives of Women who Complete the Ph.D. Degree at Midlife

Description: The percentage of women who receive doctorates has increased by over 300 percent during the past three decades. The consequences of pursuing the Ph.D. degree have always been far reaching and profound, serving as an impetus and springboard for the reconfiguration of one's beliefs, values, and professional life. The purposes of this national study were to ascertain and describe marital and social changes that occurred in the lives of women who were awarded the Ph.D. degree at midlife. A questionnaire was distributed to a sample of three-hundred women who hold the Ph.D. degree and were employed in institutions of higher education in the United States. The study sought to identify the effects of the Ph.D. experience upon the marital relationships, friendships, and social activities of women who completed the degree between the ages of thirty-five and forty-five. Demographic data were collected which were related to their marital status before, during, and after the Ph.D. experience. Both closed and open-ended questions were posed which solicited information pertaining to their post Ph.D. experience. This research reports both quantitative and qualitative findings. The majority of women who complete the Ph.D. experience at midlife undergo and initiate changes in their lives which impact their relationships and activities. Many of these changes are the result of employment which follows the award rather than the degree itself. While some women experience negative effects in some areas of their lives, overall, the findings of this study suggest that changes are perceived positively by the majority of women who receive the Ph.D. at midlife.

Retention and Attrition of Doctoral Candidates in Higher Education

Description: A number of studies have been conducted on the attrition rates of undergraduate and graduate students. However, the body of knowledge concerning attrition for doctoral students, especially those who have attained the level of “all but dissertation” (ABD), is limited. The purpose of this research was to examine retention and attrition factors of doctoral candidates from a typical Higher Education Doctoral Program (Research II Public Institution) who were admitted to candidacy from 1991 through July 2000. Participation of the subject population was limited to those who had attained the level of ABD--those who had previously fulfilled the residency, coursework, foreign language or tool-subject requirements, and successfully completed the comprehensive/qualifying exams. This population included current ABDs, previously attrited ABDs, and graduates of the degree program. The research study was qualitative and intended to identify the effect of specific, predetermined factors that may have influenced or affected the progress of current, previous, and graduated students towards the doctoral degree in higher education. This study obtained responses to questions from the questionnaire/survey instrument concerning factors that affected program completion or attrition. Students had the opportunity to elaborate on factors from their dissertation, advisement, and personal, financial, and employment experiences that affected their ability to complete the program through open-ended question responses. By examining key factors in the doctoral degree experience from the three sample groups (current ABDs, previous ABDs, and graduated Ed.Ds), this study was able to draw some conclusions about doctoral attrition. Reconstructing and comparing the experiences of ABDs from the point of candidacy to the point of attrition or completion of the program determined trends, commonalities, and issues affecting achievement. Results of this study add to the limited research concerning ABD attrition and provide an insight from the student perspective as to the obstacles and support variables in the quest for ...

The Doctoral Program in Higher Education at North Texas State University: An Appraisal

Description: Doctoral graduates of the program in Higher Education, Division of Higher Education, North Texas State University, from the fall of 1969 through spring, 1973, were selected as subjects for an evaluation of the program. To appraise the effectiveness of the program, the evaluation attempted to: (1) determine how the graduates viewed various aspects of their doctoral program and experiences at North Texas State University; (2) appraise the effectiveness of the doctoral program in Higher Education in light of the career goals and needs of the graduates and how the program served those needs; (3) present conclusions and recommendations based on the findings of the study which could aid in the administration of the program, provide information for planning new programs and policies, or in supporting those already in existence. A questionnaire was developed and used as the data-gathering instrument, after being revised according to suggestions given by a jury. The questionnaire was mailed to graduates on August 17, 1973, and a follow-up letter was mailed on September 19, 1973, to those non-respondents who could be identified. Of the total number of graduates who received the questionnaire, 69 (71 per cent) responded. Data contained in the questionnaires were numerically coded and recorded on keypunch worksheets. With the aid of the staff from the N.T.S.U. Computing Center, print-outs were produced from the worksheets which contained tabulated data. Tables were made from the data for analysis and interpretation. Analysis of the data led to the following conclusions. The program is producing graduates who have a marketable education with most of them teaching in four-year colleges and universities. The emphases on college teaching and administration are major strengths of the program and graduates rate a strong degree of satisfaction with the major program components, structure and curriculum. Competencies gained in educational research and statistics ...

What makes a quality Ph.D. program in library and information sciences?

Description: The intent of this study was to establish and validate criteria for use to assess the quality of a library and information sciences (LIS) Ph.D. program. The Ph.D. student-centric topology for quality Ph.D. programs was developed from a 2001 position statement by the American Association of Colleges of Nursing (AACN) regarding the quality indicators in research-focused doctoral programs in nursing. Topology components were tested using a survey instrument to establish their importance to the community of practice and their potential use to assess a Ph.D. program. Survey participants were asked to rank terms or concepts in a balanced incomplete block (BIB) design then rate, on a Likert-type scale, statements about the applicability of these terms or concepts to assessing a quality LIS Ph.D. program. Survey participants were from the Association for Library and Information Science Education (ALISE) Open Lib/Info Sci Education Forum jESSE Listserv. Of 225 survey participants affiliated with universities or schools from North America who submitted usable surveys, slightly less than two-thirds (64.4 %) were female while 35.5 % were male. Ninety-eight participants (43.6 %) were faculty, 114 (50.7 %) were Ph.D. students or candidates, and 13 (5.8 %) were in other roles. Statistical analysis of survey responses showed consistent results between the different demographic groups. The topology was validated by the results of the statistical analysis of the research data. Every component of the topology was acknowledged as very important to assess the quality of a LIS Ph.D. program. Faculty was the highest ranked item in the BIB analysis with a statistically significant difference (p < .0001) in the mean rank order from the next highest ranked item, Ph.D. students. The rank order from the BIB analysis was as follows: faculty, Ph.D. students, programs (courses) of study, teaching, learning environment, resources, and evaluation. Faculty was also the ...

Propagation of Density Disturbances in Air-Water Flow

Description: From Introduction: "In this work, a forced-circulation air-water loop was employed for investigating the behavior of void perturbations. Upon attaining steady-state conditions, disturbances in the void fraction were superimposed at very low frequencies (~0.4 cps). A better understanding of hydrodynamic transient behavior will generate more confidence in the design of boiling-water reactor systems."

Comparative Study of Perceived Barriers to Faculty Participation in Distance Education at a Four-Year University

Description: Bailey, Elizabeth, Comparative study of perceived barriers to faculty participation in distance education at a four-year university. Doctor of Philosophy (Education), December 2015, 103 pp., 21 tables, references. The purpose of this Bailey study was to identify perceived barriers of faculty participation in distance education courses in a four-year university and identify the differences in perceived barriers between the Hebert 2003 study and this Bailey study. The literature review covers numerous studies and articles written within the last 10 years that are related to a variety of barriers perceived by faculty and administrators. There were no statistically significant relationships found between faculty demographics including gender, age, position at the university, tenure status, and number of years faculty have taught in post-secondary education. There were no statistically significant relationships found between the top administrator-ranked motivators and corresponding faculty-ranked motivators, nor between the top administrator-ranked inhibitors and the corresponding faculty-ranked inhibitors. Out of the top four non-participating, faculty-ranked barriers, three were found to have statistically significant relationships with the corresponding administrator-ranked barriers. Statistically significant relationships were found between the faculty-ranked motivators and corresponding administrator identified motivators and between the top ranked barriers identified by non-participating faculty and administrators in Hebert’s study compared to non-participating faculty-ranked and administrator-ranked barriers identified in this study.

Legal Compliance in Guardianship Cases An Exploratory Study: Investigating Denton County Probate Court Visitors' Program Success with Legal Compliance in Guardianship Cases in 2013

Description: Dabner, Carol P. Legal Compliance in Guardianship Cases. An Exploratory Study: Investigating Denton County Probate Court Visitors' Program Success with Legal Compliance in Guardianship Cases. Doctor of Philosophy (Applied Gerontology), December 2016, 140 pp., 18 tables, references, 20 titles. Aim: To evaluate the effectiveness of the legal compliance of the Denton County Probate Court Visitor's program in the year 2013. Rationale: Guardianship case management success is based on the presence of legal compliance of both guardians and the Court. When a guardian is legally compliant, a ward is receiving the statutorily minimum standards of care. Legal compliance equates (evidence of) the Ward receiving legally sufficient care. Research has not been vast; it has been consistent as to necessity of guardianship training, monitoring, and narrow focus of research. Evidence based research will assist in defining and developing appropriate court monitoring programs, which can add to the quality of care for elderly and disabled adults. Methods: 1,300 guardianship cases in the probate court. Of these cases, 910 had annual reports of the person filed, which 304 were reviewed using the Legal Compliance Audit. Eight (8) factors of compliance were reviewed with three (3) being Court actions and five (5) being guardian actions. Results: Exploratory study provides evidence based research of the necessary changes to develop the Denton County Probate Court Visitor's program. The guardians are more legal compliant than the Court.

Energy Demands and Efficiency Strategies in Data Center Buildings

Description: Information technology (IT) is becoming increasingly pervasive throughout society as more data is digitally processed, stored, and transferred. The infrastructure that supports IT activity is growing accordingly, and data center energy demands haveincreased by nearly a factor of four over the past decade. Data centers house IT equipment and require significantly more energy to operate per unit floor area thanconventional buildings. The economic and environmental ramifications of continued data center growth motivate the need to explore energy-efficient methods to operate these buildings. A substantial portion of data center energy use is dedicated to removing the heat that is generated by the IT equipment. Using economizers to introduce large airflow rates of outside air during favorable weather could substantially reduce the energy consumption of data center cooling. Cooling buildings with economizers is an established energy saving measure, but in data centers this strategy is not widely used, partly owing to concerns that the large airflow rates would lead to increased indoor levels of airborne particles, which could damage IT equipment. The environmental conditions typical of data centers and the associated potential for equipment failure, however, are not well characterized. This barrier to economizer implementation illustrates the general relationship between energy use and indoor air quality in building design and operation. This dissertation investigates how building design and operation influence energy use and indoor air quality in data centers and provides strategies to improve both design goals simultaneously.As an initial step toward understanding data center air quality, measurements of particle concentrations were made at multiple operating northern California data centers. Ratios of measured particle concentrations in conventional data centers to the corresponding outside concentrations were significantly lower than those reported in the literature for office or residential buildings. Estimates using a material-balance model match well with empirical results, indicating that the dominant ...

A Measurement of the Top Quark Mass in 1.96 TeV Proton-Antiproton Collisions Using a Novel Matrix Element Method

Description: A measurement of the top quark mass in t{bar t} {yields} l + jets candidate events, obtained from p{bar p} collisions at {radical}s = 1.96 TeV at the Fermilab Tevatron using the CDF II detector, is presented. The measurement approach is that of a matrix element method. For each candidate event, a two dimensional likelihood is calculated in the top pole mass and a constant scale factor, 'JES', where JES multiplies the input particle jet momenta and is designed to account for the systematic uncertainty of the jet momentum reconstruction. As with all matrix element techniques, the method involves an integration using the Standard Model matrix element for t{bar t} production and decay. However, the technique presented is unique in that the matrix element is modified to compensate for kinematic assumptions which are made to reduce computation time. Background events are dealt with through use of an event observable which distinguishes signal from background, as well as through a cut on the value of an event's maximum likelihood. Results are based on a 955 pb{sup -1} data sample, using events with a high-p{sub T} lepton and exactly four high-energy jets, at least one of which is tagged as coming from a b quark; 149 events pass all the selection requirements. They find M{sub meas} = 169.8 {+-} 2.3(stat.) {+-} 1.4(syst.) GeV/c{sup 2}.

Odd-Z Transactinide Compound Nucleus Reactions Including the Discovery of 260Bh

Description: Several reactions producing odd-Z transactinide compound nuclei were studiedwith the 88-Inch Cyclotron and the Berkeley Gas-Filled Separator at the LawrenceBerkeley National Laboratory. The goal was to produce the same compound nucleus ator near the same excitation energy with similar values of angular momentum via differentnuclear reactions. In doing so, it can be determined if there is a preference in entrancechannel, because under these experimental conditions the survival portion of Swiatecki, Siwek-Wilcznska, and Wilczynski&#39;s&quot;Fusion By Diffusion&quot; model is nearly identical forthe two reactions. Additionally, because the same compound nucleus is produced, theexit channel is the same. Four compound nuclei were examined in this study: 258Db, 262Bh, 266Mt, and 272Rg. These nuclei were produced by using very similar heavy-ion induced-fusion reactions which differ only by one proton in the projectile or target nucleus (e.g.: 50Ti + 209Bi vs. 51V + 208Pb). Peak 1n exit channel cross sections were determined for each reaction in each pair, and three of the four pairs&#39; cross sections were identical within statistical uncertainties. This indicates there is not an obvious preference of entrancechannel in these paired reactions. Charge equilibration immediately prior to fusionleading to a decreased fusion barrier is the likely cause of this phenomenon. In addition to this systematic study, the lightest isotope of element 107, bohrium, was discovered in the 209Bi(52Cr,n) reaction. 260Bh was found to decay by emission of a 10.16 MeV alpha particle with a half-life of 35 ms. The cross section is 59 pb at an excitation energy of 15.0 MeV. The effect of the N = 152 shell is also seen in this isotope&#39;s alpha particle energy, the first evidence of such an effect in Bh. All reactions studied are also compared to model predictions by Swiatecki, Siwek-Wilcznska, and Wilczynski&#39;s&quot;Fusion By Diffusion&quot; theory.
