Factors Impacting the Accuracy of Self-report Perceptions of Expertise in Technology Integration

Description: The focus of this study is to determine how closely self-report perceptions of technology integration skills align with the observations of an external evaluator. Participants were elementary and secondary teachers in a north Texas school district. The district is in the process of implementing a one-to-one initiative using a major vendor’s tablet devices. The study utilized both quantitative survey methodology, and a qualitative observational tool to record learning activities in the K-12 classroom. For the quantitative phase, three validated single-item self-report instruments were administered to the teachers via an online survey; the instruments utilized were the Concerns-Based Adoption Model—Levels of Use (CBAM-LoU); Stages of Adoption of Technology; and the Apple Classroom of Tomorrow (ACOT). In the qualitative portion of the study, classroom teachers involved in the one-to-one innovation were observed and rated by the Technology Integration Matrix, an instrument specifically designed to observe technology integration skills and practices in K-12 instructional settings. Kendall’s tau correlations between the various self-report instruments and the external observer rating are: CBAM, r = .51 (p is not significant); Stages, r = .58 (p < .05); ACOT, r = .82 (p < .01). Additionally, regression models were run using all three self-reports as predictors of the observation score, and using only the ACOT as a predictor. The regression model for the three-predictor model is TIM = .68; Stages - .82; CBAM + 1.61; ACOT - 1.23 (R2 = .94, p < .05), while the model for the ACOT-only predictor is TIM = 1.1; ACOT - 1.1 (R2 = .80, p < .01). These results demonstrate a strong correlation between the ratings reported by the teachers and the ratings given by the external observer, indicating that these self-report measures show a strong propensity for indicating actual technology skills.

Factors Influencing Attitudes Toward Seeking Psychological Help in Younger and Older Adults

Description: The major purpose of this study was to test a hypothesized structural model that included many of the variables that have been found to influence people's attitudes toward seeking psychological help and investigate if these variables and their inter-relationships are different for young versus older adults. This study offers a more comprehensive investigation than previous research by testing and modifying two structural models of help-seeking attitudes, one for young adults and one for older adults. This makes it possible to examine how these variables differ for the two age groups.

Factors Influencing BI Data Collection Strategies: An Empirical Investigation

Description: The purpose of this dissertation is to examine the external factors that influence an organizations' business intelligence (BI) data collection strategy when mediated by BI attributes. In this dissertation, data warehousing strategies are used as the basis on which to frame the exploration of BI data collection strategies. The attributes include BI insightfulness, BI consistency, and the organizational transformation attribute of BI. The research population consisted of IT professionals and top level managers involved in developing and managing BI. Data was collected from a range of industries and organizations within the United States. An online survey was used to collect the data to empirically test the proposed relationships. Data was analyzed using partial least square path modeling (PLS). The results of this study suggest that there exists a positive relationship between institutional isomorphism and BI consistency. The results also indicate that there exists a positive relationship between BI consistency and BI comprehensive data collection strategy, and the organizational transformation attribute of BI and BI comprehensive data collection strategy. These findings provide a theoretical lens to better understand the motivators and the success factors related to collecting the huge amounts of data required for BI. This study also provides managers with a mental model on which to base decisions about the data required to accomplish their goals for BI.

Factors Influencing Faculty Turnover at Ten Selected Colleges of Technology/Polytechnics in Nigeria

Description: Despite numerous studies and reviews on faculty turnover, there appeared to be no systematic investigation of factors which influenced voluntary turnover among full-time faculty members in Nigerian educational institutions such as those studied here. In addition, it appeared that Nigeria lacked faculty turnover data for use in any meaningful research study. Therefore, this study investigated factors perceived to be influential among full-time faculty members leaving their jobs or institutions voluntarily. The six facets of the Job Descriptive Index developed by Smith, Kendall, and Hulin as well as a questionnaire about commitment development by Mowday, Porter and Steers elicited data concerning: present work, pay, promotion, supervision, coworkers, job in general, and commitment. Two hundred and eight (84.21%) of 247 full-time faculty members from ten selected colleges of technology/polytechnics in Nigeria became involved in this study. Means, frequencies, percentages, one-way ANOVA set at .05 level and Scheffe Test of Multiple Comparison set at .10 level were used for the analysis of data. Based on the findings, it could be established that full-time faculty members in Nigerian Colleges of Technology/Polytechnics are dissatisfied with their conditions of service. The most influential factors for voluntary turnover were pay and opportunities for promotion. Conclusions drawn from the study indicate that the demographic characteristics (gender, age, level of education, years of college teaching experience, salary grade level, college/polytechnic of employment, and region of origin) affect full-time faculty members' work attitudes. Further studies are recommended to determine policies and practices suitable for retaining the most capable full-time faculty members in Nigerian Colleges of Technology/Polytechnics.

Factors Influencing Freshmen Students' College Choice at the University of North Texas: a Focus Group Study

Description: This study focused on factors that may influence freshmen students when choosing their colleges, specifically those who attend metropolitan universities such as the University of North Texas. In addition to identifying major characteristics of the institution that attract students, it also explored the sources of information that students considered important when making their choice about where to attend college. The primary instrument for gathering the data was focus groups. These informal, small groups provided a format for in-depth discussion and probing questioning about the needs, wants and influential factors driving freshmen college choice. Ten focus groups were held with between six and ten students in a specially designed room on the campus of the University of North Texas. A professional moderator was employed and sessions were observed via a two-way mirror and tape recorded for later transcription. The major questions addressed in the focus groups included: What factors influenced students the most to attend the University of North Texas? What did they consider the level of friendliness on campus? And how did the marketing materials that the university distributed impact their decision to attend? The study found that the factors that most influenced freshmen to attend the University of North Texas were low cost, convenient location and the good academic reputation of their field of study. Students believed North Texas to have a very friendly campus and were pleased with the overall academic environment. They were not, however, impressed or greatly influenced by the marketing materials currently being used by the University and suggested ways to improve the design and distribution of these materials to make them more effective. Additional observations were made concerning these and related questions. A partial transcription of the focus group sessions is included.

Factors influencing horizontal cracking in continuously reinforced concrete pavements (CRCP).

Description: This research presents the results on an experimental investigation to identify the significant factors influencing horizontal cracking in continuously reinforced concrete pavements (CRCP). An in-depth analysis of the microstructure, morphological characteristics of the interfacial transition zone (ITZ) and the observation of cracking using the environmental scanning electron microscope (ESEM) was done. Characterization of oxides using Fourier transform infrared spectroscopy (FTIR) and electron dispersive x-ray spectroscopy (EDS) was also performed. Water to cement ratio (w/c) and rebar temperature had a significant influence on the rebar-concrete bond strength. The 28-day shear strength measurements showed an increase in rebar-concrete bond strength as the water to cement ratio (w/c) was reduced from 0.50 to 0.40. There was a reduction in the peak pullout load as the temperature increased from 14oF to 252oF for the corroded and non-corroded rebar experiments. The corroded rebar pullout test results showed a 20-50 % reduction in bond strength compared to the non-corroded rebars. FTIR measurements indicated a presence of lepidocrocrite (γ -FeOOH) and maghemite (γ -Fe2O3) on the ITZ. ESEM images showed the existence of microcracks as early as three days after casting with the bridging of these cracks between coarse aggregate locations in the interfacial zone propagating through the mortar.

Factors Influencing How Students Value Asynchronous Web Based Courses

Description: This dissertation discovered the factors influencing how students value asynchronous Web-based courses through the use of qualitative methods. Data was collected through surveys, observations, interviews, email correspondence, chat room and bulletin board transcripts. Instruments were tested in pilot studies of previous semesters. Factors were identified for two class formats. The asynchronous CD/Internet class format and the synchronous online Web based class format. Also, factors were uncovered for two of the instructional tools used in the course: the WebCT forum and WebCT testing. Factors were grouped accordingly as advantages or disadvantages under major categories. For the asynchronous CD/Internet class format the advantages were Convenience, Flexibility, Learning Enhancement, and Psychology. The disadvantages included Isolation, Learning Environment, and Technology. For the synchronous online Web based class format the advantages were Convenience, Flexibility, Human Interaction, Learning Enhancement and Psychology, whereas the disadvantages included Isolation, Learning Environment and Technology. Concurrently, the study revealed the following factors as advantages of the WebCT Forum: Help Each Other, Interaction, Socialization, Classroom News, and Time Independent. The disadvantages uncovered were Complaints, Technical Problems and Isolation. Finally, advantages specified for the WebCT testing tool were Convenience, Flexibility and Innovations, and its disadvantages were Surroundings Not Conducive to Learning, and Technical Problems. Results indicate that not only classroom preference, learning style and personality type influence how students value a Web based course, but, most importantly, a student's lifestyle (number of personal commitments, how far they live, and life's priorities). The WebCT forum or bulletin board, and the WebCT testing or computerized testing were seen mostly by students, as good tools for encouraging classroom communication and testing because of the convenience and flexibility offered. Still, further research is needed both quantitatively and qualitatively to ascertain the true weight of the factors discovered in this study.

Factors Influencing Myoelectric Wearing Patterns of Pediatric Prosthetics Patients

Description: Upper limb deficiencies in children may be the result of trauma, disease, or congenital problems. Although biomechanical losses are the primary problem associated with a limb deficiency, the loss of such an obvious body part has cosmetic and psychosocial implications as well. Fitting a child with a prosthesis typically is the treatment chosen by families. Presently, there are three types of prostheses available for pediatric amputees, including passive, cable-operated, and myoelectric arms, but the myoelectric appears to be the most popular choice of children and their families. However, there is growing concern among clinicians that, despite its advanced technological capabilities, the myoelectric prosthesis is chosen for aesthetic rather than functional reasons. It is difficult, then, to justify the expense of fitting a myoelectric prosthesis when a more inexpensive prosthesis, or none at all, would be a more appropriate prescription. The question of when to prescribe a myoelectric prosthesis for a pediatric patient remains one of the most controversial questions in the field of prosthetics today due to this cost/benefit issue. In this study, the researcher examined psychological factors that may influence whether or not a child will wear a prosthesis and how that prosthesis will be used. Thirty prosthetics patients of Texas Scottish Rite Hospital for Children and their parents answered questionnaires indicating self-perception, social acceptance, and family functioning. A prosthetic usage diary also was completed. Results indicated a significant relationship between optimal residual limb length and increased wearing time. Other trends in the data are discussed. Consideration of these variables by medical staff can be useful in developing appropriate expectations of adherence to treatment by the patient and the family. Recommendations are made for the prescription of pediatric prostheses that are both cost-effective and beneficial.

Factors Influencing Older Adults' Patterns of Information Acquisition

Description: A group of 101 older adults (sixty-five years of age and over) who lived independently in three retirement apartment residences in Denton, Texas, were asked about their patterns of reading, television viewing, and radio listening habits for two periods in their lives: (1) at age forty to fifty-five and (2) at the present. Respondents were asked about their use of external information sources (public library, grocery store, newsstand, etc.) and their use of proximate information sources (radio, friends/relatives, television, etc.) They were also asked about access to transportation, income satisfaction, status of general health, vision, hearing, physical mobility and reasons for utilizing various information sources. Four hypotheses relating changes in health, environment, economic status, and education to reasons for reading and use of information sources were tested through the use of t-tests, regression analysis and analysis of variance. Within this group of older adults, use of external information sources decreased from the past to the present. There was, however, no change in the use of information sources located in or near the residence as difficulties in these areas increased. A relationship was found between educational level and reading for pleasure earlier in life. Also, those with higher educational levels reported fewer differences in their reasons for reading in the present and in the past.

The Factors Influencing Out-of-State Companies to Establish Manufacturing Facilities in Dallas County

Description: "The purpose of this study was to collect and analyze locational data on all branch maufacturing plants established in Dallas County in 1954, 1955, and 1956; these data were acquired through personal interviews in 1957. For comparative purposes the same data on branch plants established in 1959 were obtained in 1960. The following elements of the locational process were determined and analyzed: 1. Origin and character of the new plants; specifically location of home office, types of products, size and location of the plant in Dallas. 2.locational process, including company personnel assigned the task of locating a suitable site and local agencies assisting in the locational process. 3. reasons for establishing the branch plant 4. factors that influenced management to locate the plant inDallas in preference to any other locations."-- leaf 4.

Factors influencing parental attitudes toward digital game-based learning.

Description: The purpose of this non-positivistic mixed-methods study is to examine parental attitudes towards the use of computer and video games in their child’s classroom and to investigate how the sociocultural contexts in which parents live affect those attitudes. The research was conducted using a mixed-methods triangulation design, including both quantitative and qualitative techniques. First, the study tried to identify which groups of parents were better positioned to accept and support digital game-based learning and which groups were less likely to have a positive attitude toward integrating digital games into the classroom. This study tried to determine if socioeconomic status, age, education level, and/or cultural background could serve as a predictor of parental attitudes toward digital game-based learning. Second, the study tried to recognize how social and cultural contexts in which parents live affect their attitudes toward digital games in the classroom. Many researchers agree that parents play an important role in students’ and eventually, educators’ attitudes toward gaming. It has been argued that if parents accept a certain non-traditional (digital) learning tool, then their children would most likely have a similar attitude toward it. Parents might be the support system that educators need in order to ensure that students are able to see the educational value of video games and are willing to think critically and draw connections between what they learn in a gaming environment and core subject areas.

Factors Influencing Post-adoptive Enterprise Resource Planning (ERP) Utilization

Description: Organizations expend a great deal of time, effort and money on the implementation of enterprise resource planning (ERP) systems. They are considered the price of entry for large organizations to do business. Yet the success rate of ERP systems is poor. IS literature suggests that one possible reason for this is the underutilization of these systems. Existing ERP literature is replete with research to improve ERP project implementation success; however, notably absent from these streams is the research that identifies how ERP systems are utilized by individuals or organizations. This dissertation posits that increased ERP utilization can result from increased software and business process understanding gained from both formal training and experiential interventions. New dimensions of system utilization (required vs. optional) are proposed. The purpose of this dissertation is to examine how these interventions impact ERP utilization. The results of this dissertation show that while software-training interventions are important to understanding, it is the business process training interventions that seem to provide the greater effect on understanding. This increased understanding positively affects utilization scenarios where a mixture (required vs. optional) of software features and business process tasks can be leveraged by end-users. The improved understanding of post-adoptive ERP utilization gained from this study benefits both researchers and practitioners.

Factors Influencing Psychological Empowerment of Nurse Aides in Nursing Homes

Description: The purpose of this study is to identify predictors of psychological empowerment among nurse aides in nursing homes. Five structural factors (information exchange, decentralization of resources, co-worker support, supervisor support, and availability of training) and four control factors (age, sex, level of education, and race) are analyzed using multivariate linear regression to examine their effects on psychological empowerment. Two of the five structural factors, decentralization of resources and supervisor support, are shown to positively influence psychological empowerment. Nursing home managers can consider developing and implementing procedures that decentralize resources and demonstrate supervisor support in order to increase psychological empowerment. Based on the findings of this study theory and practice might benefit from additional study of decentralization of resources and supervisor support.

Factors Influencing Student Achievement in Texas

Description: This study examines the relationships among student socioeconomic status, school district enrollment, minority enrollment, district expenditure per pupil, and the teaching experience of faculty as these variables influence the achievement scores of secondary students in Texas. Data from a total of 1,061 Texas school districts were used to determine the effects of the indicated district-level predictor variables on three criterion variables: reading, mathematics, and writing scores for the 11th-grade Texas Education Assessment of Minimum Skills (TEAMS). The study led to the following conclusions: 1. Low socioeconomic status of students in Texas, as in the rest of the United States, insures that test scores will be lower if all other variables are held constant. 2. Large minority populations are strong predictors of low test scores, especially in mathematics and reading. 3. Students in districts whose faculty had a high average of years of teaching experience also scored high in achievement tests, especially in mathematics and writing. 4. High average district expenditure per pupil predicts high test scores, especially in reading. 5. School district size or enrollment has low predictive value of test scores. Among several specific recommendations, this study advises that further study be done concerning the most effective ways to educate minority and socioeconomically disadvantaged student populations. The study also recommends that better ways be found to retain experienced teachers in the classroom, including monetary compensation, extra allowances for staff development, and additional resources. The study cautions against simply adding money to a district's budget to increase student achievement scores, asserting that districts should make thorough studies before higher expenditures per pupil are alone used to increase test scores.
