Japanese Students' Perceived Need For Communicative English And Their Perceived Proficiency Levels, Takanori Mita

Dissertations

Japanese students of English need to develop their proficiencies not only in oral aspects but in overall practical language aspects. English programs from junior high school to college levels need to be improved in consideration of current needs of students.

This study was conducted to assess college students’ perceived need for changes in the English curricula enhancing communicative competence and to seek their perceived levels of proficiency at graduation in the four skill areas (listening, speaking, reading, and writing) in relationship with students’ majors, academic experience in English-speaking countries, and lengths of such experience.

The research was conducted in Tokyo …

Symbolic Politics: Government's War Against The Working Class, Warren Charles Gregory

Dissertations

Symbolism and substance are essential parts of any political system. In our system of government, we typically think of symbolism as serving substantive ends. Using a triangulation of _methods (Participant Observation, Archival Data, and Documentary Evidence), the paper examines two cases (Social Security and criminal justice) and concludes that the mix between substance and symbolism has changed dramatically in recent years with symbolism now assuming the central role.

The current debates over Social Security funding and criminal justice sanctions, for example, are less about the concerns of old-age security or making the public safer as much as they reflect a …

Demographic information as well as subjects’ level of participation in several activities …

Students’ Conceptions Of Mathematics And The Transition From A Standards-Based Reform Curriculum To College Mathematics, Rebecca K. Walker

Dissertations

Students’ conceptions of mathematics are shaped by the environment within which they learn mathematics and in turn they affect the manner in which students engage in mathematics.

This study examined students’ conceptions about learning, knowing, and doing mathematics after studying four years of a Standards-based reform high school mathematics curriculum developed by the Core-Plus Mathematics Project (CPMP). Student conceptions were examined at the end of high school (n = 2S6) and after one semester of college mathematics (n = 92). The study also provides case studies of six students as they navigated from the CPMP curriculum through college Precalculus or …

Majority And Minority Supervisees' Perceptions Of Clinical Supervision, Vivian Barnette

Dissertations

Perceptions of clinical supervision of 175 majority and minority counseling psychology doctoral students selected from a national pool was the study’s focal point. Instruments used were the Revised Relational Inventory (RRI; Barrett- Lennard, 1962; Schacht, Howe, & Berman, 1988) and the Supervision Perception Form-Trainee (SPF-T) developed by Heppner and Roehlke (1984). Participants were instructed to based their ratings on their last supervision experience. Data were collected and scored on the five subscales o f the RRI (Congruence, Empathetic Understanding, Regard, Unconditionality, and Willingness to be Known) and the two subscales of the SPF-T (Willingness to Learn and Supervisory Impact).

Site-Based Management And Student Achievement, Roxana Marie Hopkins

Dissertations

The question that this study seeks to answer is. Does site-based management increase student achievement? Researchers believe that when a school can function more like a closed system, involved in site-based decision making, the culture of the organization may be more conducive to higher student achievement. This study has attempted to determine if there is a basis for this belief.

Supporting the study are three organization theories. Bureaucracy Theory, Systems Theory, and Human Resource Development Theory. These three theories run like threads in a tapestry throughout the research and legislation upon which this research is developed.

A Comparison Of International And U.S. Students In Apa-Accredited Programs: Acculturation, Counseling Self-Efficacy And Role Difficulties In Supervision, Johanna E. Nilsson

Dissertations

There has been a call in the multicultural supervision literature to enhance the understanding of minority students’ unique training needs and develop appropriate theories and models of training for these students (Leong & Wagner, 1994; McNeill, Horn, & Perez, 1995). Although a few researchers have empirically examined differences between U.S. majority and minority students in multicultural supervision (Cook & Helms, 1988; Vander Kolk, 1974), virtually no empirical studies have been published on international students’ training experiences.

The main purpose of the present study was to advance knowledge regarding the training needs of international students in APA-accredited programs in psychology. It …

Evaluating The Effects Of Postive Peer Reporting On Social Acceptance, Mary Short

Dissertations

The effects of a positive peer reporting procedure on social status and social interactions were assessed. Children who are socially rejected seem to be disliked by their peers due to their high frequency of negative behaviors and low frequency of positive behaviors. Therefore, to decrease the negative behaviors and increase the positive behaviors, rejected children were asked to make positive comments about their peers. Participants included 4 children, ages 10-15 years. A multiple baseline across subjects design was utilized. Collection of baseline data began immediately following the confirmation of consent and eligibility for the child to participate. Initial baseline data …

Case Studies Of Organizational Evaluation In Community Foundations, Joyce Box Brown

Dissertations

Community foundations are classified as public charities (501(c) 3). They derive their funds from many donors rather than a single donor, and the board is made up of representatives from the community served. They are most often established to serve a specific geographic area. This study investigated and described how three different community foundations approach organizational evaluation— choosing proposals to fund, monitoring programs, improving programs, and assessing program impact.

The three community foundations approach evaluation not as a formal system of grant accountabilities, but as a way of systematically gathering information from various constituents for purposes of guiding important decisions. …

Intuitive Understanding Of Time And Space At The Age Of Four, Josephine Barry-Davis

Dissertations

The purpose of this study was to test the central hypothesis that “children by the age of four years construct accurate and lasting conceptions o f time (past, present, future) and space (near and far away).” In order to test this hypothesis the researcher relied on qualitative research guidelines developed and published in recent years to address social science and educational research issues. The research design is especially applicable to young children where the researcher assumes the role of participant observer. In order to control for the context of the research, the children were observed for time and space cognitive …

Improving Special Education Teachers' Use Of Data-Based Instruction, Steven D. Goodman

Dissertations

The data-based decision model involves frequent measures of student performance (i.e., 2 - 5 times per week), frequent analysis of performance data (weekly or bi-weekly), and the application of decision rules. In the first study, we surveyed 406 special education teachers state-wide. Results of the survey suggest that the databased decision model is not generally practiced by special educators in the field. Just over one quarter of the respondents report to assessing student performance frequently enough to qualify as using the model. Only 10% of respondents indicate that they generally graph student performance. Additionally, less than 23% of respondents who …

“All Things Considered”: A Comparative Case Study Examining The Commercial Presence Within Public Radio, Peter P. Nieckarz Iii

Dissertations

This dissertation addresses the commercial presence within public radio. A case study of three NPR affiliate stations was conducted to determine to what extent public radio is being influenced or compromised by increased commercial rationality. It also addresses how they have been able to resist commercialism and remain true to the original ideals of public radio. The research included active interviews, observations, and document analyses of data collected from field research at each o f the three stations in the sample. Analysis of the data indicates that public radio stations have grown more commercial due to declining tax-based subsidies, and …

A Study Of The Relationship Between Transformational Leadership And Teacher Attitudes, Scott Palczewski

Dissertations

One hundred Michigan public high schools were randomly selected to participate in a study of the relationship between transformational leadership and teacher attitudes. Forty-eight high schools with enrollments ranging from 237 students to 1,730 students responded, a response rate of 48%. The study required that each building principal complete the Multifactor Leadership Questionnaire. Designed by Bass and Avolio (1990), the instrument uses 45 questions to identify the relative level of transformational leadership exhibited by the building principal.

Five dependent variables including teacher motivation, teacher satisfaction with administration, follower identification with work, teacher willingness to disagree with administration and teacher attitudes …

The Role Of Access In Evaluating Distance Learning Program Effectiveness, Carole A. Richardson

Dissertations

Distance learning technologies are increasingly used within public post-secondary institutions as a way to deliver courses to students remote from the home campus. Many proponents of distance learning argue that its use provides a method for reaching the educationally undeserved, i.e., those who lack access to higher education. If a distance learning program decreases access barriers, then it is congruent with traditional American values of providing universal access to education to all citizens. Distance learning program evaluation strategies, therefore, need to include a means of measuring the extent to which access goals are met.

The purpose of this study is …

The Effects Of Sibling-Implemented Training On Social Behaviors Of Autistic Children, Cristin L. Sullivan

Dissertations

The present study investigated the effectiveness of sibling-implemented pivotal response training (PRT) on the social behaviors of five children with autism. Using a multiple-baseline design across sibling pairs, participants were trained to use PRT while playing with their brother’s with autism. Measures of play skills and social behavior were assessed during baseline, training, sibling-independent play, and two-month follow-up sessions. Also, parents were asked to rate randomly selected video-tape segments from baseline and sibling-independent play sessions. The results indicated that siblings were able to learn effectively and implement PRT strategies following training. All of the children with autism demonstrated an increase …

An Analysis Of Grade-Level Expenditures Of At-Risk Funding Among Districts Of Different Economic Status In The State Of Michigan, Benard A. Meyer

Dissertations

Many of the recent financial reforms failed to address the needs of at-risk children. Effective solutions to the problems of the educationally disadvantaged must include changes within the schools, how the schools are funded, and how the schools spend their funding. Michigan’s 1994 finance reform included a funded plan for “unequal treatment of unequals” directed for the support of at-risk students. This fund was called Section 31a Program for At-Risk Pupils and involved a 230 million dollar compensatory education funding allowance for students at risk of school failure. This study presented here will determine if there is a relationship between …

Adaptive Interference Cancelation Techniques For Multicarrier Modulated Systems, Matthijs A. Visser

Dissertations

Current wireline systems and wireless broadcasting systems employ multicarrier modulation (MCM). This includes the high-rate digital subscriber line (HDSL), digital audio broadcasting system (DAB) and the digital terrestrial television broadcasting system (dTTb). Multicarrier modulation is also envisioned for high-speed indoor wireless local area networks (WLAN). Additionally, multicarrier code division multiple access (MC-CDMA), a hybrid of orthogonal frequency division multiplexing (OFDM) and CDMA, is proposed for the downlink (base-to-mobile) of a 3rd generation wireless system as part of the IMT-2000 standardization process.

The performance of an MC-CDMA system--similar to a direct sequence CDMA (DS-CDMA) system--is limited by the presence of multiple …

Developing Techniques For Enhancing Comprehensibility Of Controlled Medical Terminologies, Huanying Gu

Dissertations

A controlled medical terminology (CMT) is a collection of concepts (or terms) that are used in the medical domain. Typically, a CMT also contains attributes of those concepts and/or relationships between those concepts. Electronic CMTs are extremely useful and important for communication between and integration of independent information systems in healthcare, because data in this area is highly fragmented. A single query in this area might involve several databases, e.g., a clinical database, a pharmacy database, a radiology database, and a lab test database.

Unfortunately, the extensive sizes of CMTs, often containing tens of thousands of concepts and hundreds of …

Porting The Sisal Functional Language To Distributed-Memory Multiprocessors, Jui-Yuan Ku

Dissertations

Parallel computing is becoming increasingly ubiquitous in recent years. The sizes of application problems continuously increase for solving real-world problems. Distributed-memory multiprocessors have been regarded as a viable architecture of scalable and economical design for building large scale parallel machines. While these parallel machines can provide computational capabilities, programming such large-scale machines is often very difficult due to many practical issues including parallelization, data distribution, workload distribution, and remote memory latency.

This thesis proposes to solve the programmability and performance issues of distributed-memory machines using the Sisal functional language. The programs written in Sisal will be automatically parallelized, scheduled and …

On Scheduling Input Queued Cell Switches, Shizhao Li

Dissertations

Output-queued switching, though is able to offer high throughput, guaranteed delay and fairness, lacks scalability owing to the speed up problem. Input-queued switching, on the other hand, is scalable, and is thus becoming an attractive alternative. This dissertation presents three approaches toward resolving the major problem encountered in input-queued switching that has prohibited the provision of quality of service guarantees.

First, we proposed a maximum size matching based algorithm, referred to as min-max fair input queueing (MFIQ), which minimizes the additional delay caused by back pressure, and at the same time provides fair service among competing sessions. Like any maximum …

On-Line State And Parameter Estimation In Nonlinear Systems, David A. Haessig

Dissertations

On-line, simultaneous state and parameters estimation in deterministic, nonlinear dynamic systems of known structure is the problem considered. Available methods are few and fall short of user needs in that they are difficult to apply, their applicability is restricted to limited classes of systems, and for some, conditions guaranteeing their convergence don't exist.

The new methods developed herein are placed into two categories: those that involve the use of Riccati equations, and those that do not. Two of the new methods do not use Riccati equations, and each is considered to be a different extension of Friedland' s parameter observer …

Automatic Document Classification And Extraction System (Adoces), Xuhong Li

Dissertations

Document processing is a critical element of office automation. Document image processing begins from the Optical Character Recognition (OCR) phase with complex processing for document classification and extraction. Document classification is a process that classifies an incoming document into a particular predefined document type. Document extraction is a process that extracts information pertinent to the users from the content of a document and assigns the information as the values of the “logical structure” of the document type. Therefore, after document classification and extraction, a paper document will be represented in its digital form instead of its original image file format, …

Knowledge Management For Texpros, Jianshun Hu

Dissertations

Most of the document processing systems today have applied Al technologies to support their system intelligent behaviors.

Fdtd-Based Full Wave Co-Simulation Model For Hybrid Electromagnetic Systems, Tong Li

Dissertations

In high-frequency ranges, the present electronic design automation software has limited capabilities to model electromagnetic (EM) systems where there are strong field effects influencing their characteristics. In this situation, a full-wave simulation tool is desired for the analysis and design of high-speed and non-linear EM systems. It is necessary to explore the interaction between the field and electronic components during a transient process when field effects are more significant. The finite-difference time-domain (FDTD) technique receives growing attention in the area of EM system analysis and simulation due to its simplicity, flexibility and robustness. It is a full-wave simulation method that …

A New-Generation Class Of Parallel Architectures And Their Performance Evaluation, Qian Wang

Dissertations

The development of computers with hundreds or thousands of processors and capability for very high performance is absolutely essential for many computation problems, such as weather modeling, fluid dynamics, and aerodynamics. Several interconnection networks have been proposed for parallel computers. Nevertheless, the majority of them are plagued by rather poor topological properties that result in large memory latencies for DSM (Distributed Shared-Memory) computers. On the other hand, scalable networks with very good topological properties are often impossible to build because of their prohibitively high VLSI (e.g., wiring) complexity. Such a network is the generalized hypercube (GH). The GH supports full-connectivity …
