The Effect of Two Methods of Programming upon the Development of the Orchestra in a Secondary School

Description: The present study was designed for the purpose of comparing the effectiveness of two methods of orchestral programming, demonstration and non-demonstration, upon (1) the musical perception of the members of a student body audience, and (2) the attitudes of the members of a student body toward orchestra as a school subject. This comparison of demonstration and non-demonstration programming involved the question concerning the effectiveness of instructive listening as compared with free listening in the development of musical perception and attitudes. The problem of the present study is presented in the following major areas: (1) musical perception, end (2) attitudes.

The Effect of Type A and Type B Personality and Leadership Style on Absenteeism

Description: This study explored the relationship of Type A/B personality and leadership style to absenteeism. Absenteeism data were gathered for 243 male fire fighters and fire engineers. Each subject was administered the Jenkins Activity Scale to measure his Type A characteristics and the Leader Behavior Description Questionnaire to measure his perception of his supervisor's leadership style. The results, though non-significant, revealed that: a) Type A's had less absenteeism than type B's; b) Subjects who perceived their supervisors as being low on consideration had less absenteeism than those who perceived their supervisors as being high on this dimension; c) Type A's absenteeism was low and Type B's was high when working under a leader perceived as low on structure. Finally, a weak but significant three-way interaction effect revealed that the highest amount of absenteeism occurred when Type B' s worked under supervisors who were high in consideration and low in structure. The least amount of absenteeism occurred when Type A's worked under supervisors who were high in structure and low in consideration.

The Effect of Using Class Discussion as a Pre-Writing Activity in Teaching Composition to ESL Students

Description: This study examines the effect of class discussion as a pre-writing activity on actual writing performance. The experiment was conducted with all the Level 3 and Level 4 students enrolled in the Intensive English Language Institute of North Texas State University in the Spring, 1986 semester. Cochrans C test was performed to test significant differences between groups at the beginning of this test. Multivariate analysis of variance tests were used to determine the treatment effect between and within groups, and a matched t-test was also utilized to analyze the difference within tests. Pearson product moment correlation coefficient was calculated to determine the relationship between the discussion activity score and the actual writing score. Analysis of covariance tests were used to determine which variance of discussion activities had greater effect on the actual writing score.

The Effect of Value Co-creation and Service Quality on Customer Satisfaction and Commitment in Healthcare Management

Description: Despite much interest in service quality and various other service quality measures, scholars appear to have overlooked the overall concept of quality. More specifically, previous research has yet to integrate the effect of the customer network and customer knowledge into the measurement of quality. In this work, it is posited that the evaluation of quality is based on both the delivered value from the provider as well as the value developed from the relationships among customers and between customers and providers. This research examines quality as a broad and complex issue, and uses the “Big Quality” concept within the context of routine healthcare service. The last few decades have witnessed interest and activities surrounding the subject of quality and value co-creation. These are core features of Service-Dominant (S-D) logic theory. In this theory, the customer is a collaborative partner who co-creates value with the firm. Customers create value through the strength of their relations and network, and they take a central role in value actualization as value co-creator. I propose to examine the relationship between quality and the constructs of value co-creation. As well, due to the pivotal role of the decision-making process in customer satisfaction, I will also operationalize the value co-creation construct. Building upon the “Big Quality” concept, this study suggests a new approach by extending the quality concept to include the value-creation concept in Service Dominant Logic. This study identifies the associated constructs and determinants of Big Quality in routine healthcare management service, and examines the relationship among the associated quality constructs, customer satisfaction, and customer commitment. This study employed an online survey methodology to collect data. In data analysis, I used the variance-based structural equation modeling (PLS-SEM) approach to confirm the factor structure, proposed model, and test the research hypotheses. The results show that the customer’s ...

The Effect of Verbal and Graphic Feedback on Direct Care Trainers' Data-Tecording Behavior

Description: This study investigated the effects of verbal and graphic feedback alone and in combination with praise on the data-recording behavior of 12 direct care trainers (DCTs) who recorded their reinforcer deliveries as they interacted with mentally retarded clients. An additional variable examined was the effect of time of delivering feedback on subsequent data-recording behavior. Feedback was delivered by the experimenter. Correspondence checks were conducted and a three-phase multiple condition experimental design was used. All feedback conditions produced an observable difference in DCT data-recording behavior. Time of delivery of feedback also appeared to have an effect on the amount of data recorded by DCTs.

The Effect of Web-Based Support as an Adjunct to a Self-Help Smoking Cessation Program

Description: For the past quarter century, the public has been educated and warned about the dangers of smoking, and both smokers and health researchers have been in search of cost-effective, smoking cessation programs that will lead to long-term cessation. This study used a randomized experimental design to investigate the effectiveness of adding Web-based support materials to a nationally sponsored self-help smoking intervention. There was no significant increase in abstinence rates nor progression through the stages of change by those participants who had access to the Web site. However, there were some overall significant trends that suggested these self-help interventions were successful at decreasing daily rates of smoking and nicotine dependency, as well as tended to encourage repeated quit attempts. Although Web-based supports did not appear to increase the effectiveness of the nationally sponsored self-help intervention, this study demonstrated overall 12 week follow-up abstinence rates of 30-32%--greater than what might be expected, given average success rates of other self-help interventions. This study also supports the notion that women may face additional barriers to smoking cessation. Limitations and implications for future research are discussed.

The Effect of Work-Study Methods Instruction on Student Achievement in Fifth Grade Social Studies

Description: The problem with which this investigation is concerned is the effect of work-study method instruction upon the achievement of students in fifth grade social studies. The purpose of this investigation is to determine the effects of the SQ3R (Survey, Question, Read, Recite, Review) Study Method instruction upon the achievement of students in fifth grade social studies. The subjects ranged in age from ten years two months to thirteen years three months. Th I.Q. for the subjects ranged from 70 to 135. Of the 102 subjects involved in the study, 42 were male and 60 were female. The I.Q. score from the California Test of Mental Maturity, S Form was used to structure the subjects into three intelligence levels. Fifty-four subjects served as the experimental group, and forty-eight served as the control group. The instrument used to obtain pretest and posttest scores on the variable relating to achievement was the SRA Assessment Survey, Blue Level. Form E was used for the pretest, and Form F was used for the posttest. The subjects were assigned to four classes which were near equal. Two classes were selected by the principal to serve as the experimental group. The other two classes served as the control group. The investigator spent equal time with the control and the experimental group. The four classroom teachers rotated between experimental and control groups on an equal basis. Students in the experimental group met nineteen times during the study for a thirty-minute period. During these sessions, the experimental subjects used the SQ3R Study Method to do social studies assignments. The control group met for the same number of sessions and for an equal amount of time. They worked with the same content but without using the SQ3R Study Method. The analysis of covariance was employed with pretest scores as the ...

The Effect on Group IQ Test Performance of Modification of Verbal Repertoires Related to Motivation, Anxiety, and Test-Wiseness

Description: To investigate the efficacy of a cognitive approach applied to problems of motivation, anxiety, and test-wiseness in a group test situation, programmed texts were used to Condition a repertoire of verbal responses relevant to each of these problems. Five sixth grade classes composed of 118 Students total were administered Otis-Lennon Mental Ability Tests in a pretest-posttest design. For the five groups, ANCOVA demonstrated a significant effect on raw scores, but not on IQ. Significant IQ and raw score gains were found for the combination group over the control group. Due to treatment lower IQ level students of the combination group made greater raw score gains than upper IQ level students.

The Effect on Learning of Geographic Instruction Designed for Students' Verbal and Spatial Abilities

Description: The purpose of this study was to compare student scores on geographic skills in the experimental group with student scores on geographic skills in the control group after adjustment was made in teaching methods and learning materials for verbal and spatial ability for students in the experimental group. Hypotheses tested at the .05 level were as follows. 1. Females would score higher than males on a criterion measure of verbal ability. 2. Males would score higher than females on a criterion measure of spatial ability. 3. Experimental/verbal students would score higher on a geography skills posttest. 4. Experimental/spatial students would score higher on a geography skills posttest. 5. The experimental group would score higher than the control group on a geography skills posttest. The sample was 150 high school United States History students in a medium-sized North Texas school district. Analysis of covariance was used to analyze results of the study of six classes after fifteen days of instruction in physical geography concepts. Experimental classes received geographic instruction directed to verbal and spatial abilities; control group classes received traditional geographic instruction which utilized textbook, lecture, and whole-group instruction. Three high schools participated in the study. Conclusions were that males and females did not differ significantly on verbal and spatial abilities. Values between pretest and posttest for both experimental and control groups were significant, but when adjusted for the covariates of verbal and spatial ability, control/verbal learners' posttest scores were significantly higher than experimental/verbal learners' posttest scores. Spatial/ experimental learners' posttest scores and spatial/control learners' posttest scores were compared, and the result was no significant difference when cell means were adjusted for the higher spatial/experimental learners' spatial ability. The practice of teaching geography through the use of textbook and whole-group instruction resulted in larger learning gains than the practice of using ...

Effect Size Reporting and Interpreting Practices in Published Higher Education Journal Articles

Description: Data-driven decision making is an integral part of higher education and it needs to be rooted in strong methodological and statistical practices. Key practices include the use and interpretation of effect sizes as well as a correct understanding of null hypothesis significance testing (NHST). Therefore, effect size reporting and interpreting practices in higher education journal articles represent an important area of inquiry. This study examined effect size reporting and interpretation practices of published quantitative studies in three core higher education journals: Journal of Higher Education, Review of Higher Education, and Research in Higher Education. The review covered a three-year publication period between 2013 and 2015. Over the three-year span, a total of 249 articles were published by the three journals. The number of articles published across the three years did not vary appreciably. The majority of studies employed quantitative methods (71.1%), about a quarter of them used qualitative methods (25.7%), and the remaining 3.2% used mixed methods. Seventy-three studies were removed from further analysis because they did not feature any quantitative analyses. The remaining 176 quantitative articles represented the sample pool. Overall, 52.8% of the 176 studies in the final analysis reported effect size measures as part of their major findings. Of the 93 articles reporting effect sizes, 91.4% of them interpreted effect sizes for their major findings. The majority of studies that interpreted effect sizes also provided a minimal level of interpretation (60.2% of the 91.4%). Additionally, 26.9% of articles provided average effect size interpretation, and the remaining 4.3% of studies provided strong interpretation and discussed their findings in light of previous studies in their field.

Effective and Accelerated Informative Frame Filtering in Colonoscopy Videos Using Graphic Processing Units

Description: Colonoscopy is an endoscopic technique that allows a physician to inspect the mucosa of the human colon. Previous methods and software solutions to detect informative frames in a colonoscopy video (a process called informative frame filtering or IFF) have been hugely ineffective in (1) covering the proper definition of an informative frame in the broadest sense and (2) striking an optimal balance between accuracy and speed of classification in both real-time and non real-time medical procedures. In my thesis, I propose a more effective method and faster software solutions for IFF which is more effective due to the introduction of a heuristic algorithm (derived from experimental analysis of typical colon features) for classification. It contributed to a 5-10% boost in various performance metrics for IFF. The software modules are faster due to the incorporation of sophisticated parallel-processing oriented coding techniques on modern microprocessors. Two IFF modules were created, one for post-procedure and the other for real-time. Code optimizations through NVIDIA CUDA for GPU processing and/or CPU multi-threading concepts embedded in two significant microprocessor design philosophies (multi-core design and many-core design) resulted a 5-fold acceleration for the post-procedure module and a 40-fold acceleration for the real-time module. Some innovative software modules, which are still in testing phase, have been recently created to exploit the power of multiple GPUs together.

Effective Public Service Collaboration: The Role of Leadership and Nonprofit Organizations in Homeless Services

Description: This dissertation investigates factors that facilitate effective collaboration of networks functioning within the context of a federal homeless policy—the HEARTH Act of 2009. While the federal legislation encourages networked collaboration to address the incidence of homelessness, not all networks are effective in achieving their intended purpose. Using a nationwide sample of homeless networks, this research explores the role that nonprofit organizations play in the collaborative process and models the effect of individual leadership, nonprofit-led network, and community nonprofit capacity on two levels of network effectiveness—network and community—using multivariate regression modeling. Results indicate that nonprofits play a significant role as participants of the collaboration process and as leading agents of homeless networks. In addition, the variation in network effectiveness is explained by multidimensional factors.

Effective Teachers in an Effective School: A Case Study

Description: The purpose of this investigation was to describe the behavior of effective teachers working within the context of an effective school. The study focused on both the content and techniques of instruction utilized by the teachers. In addition, the research examined teacher behaviors that were external to the classroom setting, including teacher-to-teacher relationships, teacher-to-parent relationships, and teacher-to-principal relationships. A qualitative research design was selected for this study. The site was an inner city elementary campus. Data were collected from eleven K-3 teachers using participant observation and interviews over a seven-month period. Documents were also used as a source of data. The analysis of data was ongoing and cyclical based on the constant comparative method. The final analysis of data resulted in nine themes based on recurring patterns of teacher behavior. The findings suggest that a caring school culture plays an important role in a school's success and the effectiveness of its teachers. Furthermore, there does not appear to be a universal description that fits all effective teachers. Instead, effective teachers in an effective school function as autonomous decision makers in their classrooms, choosing the curriculum and techniques that work best for them and their students. They tend to focus on basic skills, especially reading and mathematics, using explicit direct instruction methods. However, these teachers frequently digress from their planned lessons to teach life skills and test-taking strategies. Findings for this study also support the creation of structured school and classroom environments for low-income inner city students. Student self-esteem and parental support are not negatively impacted when firm discipline is administered fairly in a caring, supportive school climate. The conclusions of this investigation have implications for teacher staff development and campus administrator training. The findings also suggest further research in the areas of school culture, direct instruction, student discipline, and classroom ...
