A Low-Complexity Hardware Implementation Of Discrete-Time Frequency-Selective Rayleigh Fading Channels, Fei Ren, Yahong R. Zheng

Electrical and Computer Engineering Faculty Research & Creative Works

A low-complexity hardware implementation method is proposed for discrete-time frequency-selective Rayleigh fading channels. the proposed method first employs the Sum-of-Sinusoids method to generate multiple independent flat fading channel responses, then utilizes a simple weight-delay-sum filtering method to incorporate the fractionally delayed multipath rays into inter-tap correlated tap gains. It thus achieves accurate correlation properties in both inter-tap correlation and temporal correlation (or Doppler spectrum). the proposed method is implemented by an Altera Stratix II FPGA development kit and the results show excellent performance match with those by MATLAB software simulations. ©2009 IEEE.

Biologically Plausible Speech Recognition Using Spike-Based Phase Locking Cues, Ismail Uysal, John G. Harris

Electrical and Computer Engineering Faculty Research & Creative Works

A biologically plausible algorithm is proposed for phoneme recognition that makes use of spikes for computation. The prototype system is demonstrated on voiced phonemes and shows competitive performance with state-of-the-art systems on a vowel dataset in the presence of noise. Using novel phase locking cues, the algorithm performs surprisingly well down to SNR values as low as 5dB, where the performance of the baseline algorithm used for comparison drops considerably. These results suggest, not only a possible explanation for the extreme noise robustness of human recognition, but also a novel technique for information processing for speech signals with computers. ©2009 …

Interview With Audrey Boutte And Agnes Tebo, Audrey Boutte, Agnes Tebo, California State University, Monterey Bay

Chinatown Renewal Project

The majority of the content is the story of Audrey Boutte and Agnes Tebo's lives. It begins with their descriptions of moving from Louisiana and Texas and coming to Salinas. Agnes speaks about the need for a job and how much better California pays compared to Texas, and Audrey speaks about the standard of living improving greatly compared to Louisiana. Both Agnes and Audrey briefly speak about the racial discrimination that they and their families experienced both in Salinas and in Texas and Louisiana. Chinatown is spoken about sparingly throughout the interview because it is a sensitive subject for Audrey …

Making Cooperative Learning Visible Without The Group Grade, Jeannette Kindred

The Scholarship of Teaching and Learning at EMU

Jenny Kindred wrestles in this chapter with a dilemma many of us have faced: how to grade group assignments. I suspect many people reading this have a memory of getting a lower grade than we deserved in a group project because a fellow group member didn’t pull his or her weight. My experience with this has always made me shy away from giving group grades. And yet, others convincingly argue that group grades are required in order to build a cohesive group rather than a collection of individuals who happen to be working on the same project. Since group work …

Supersymmetric Lattices - A Brief Introduction, Simon Catterall

Physics - All Scholarship

Recently, new theoretical ideas have allowed the construction of lattice actions which are explicitly invariant under one or more supersymmetries. These theories are local and free of doublers and in the case of Yang-Mills theories also possess exact gauge invariance. In this talk these ideas are reviewed with particular emphasis being placed on {\cal N}=4 super Yang-Mills theory.

The Relationship Of Self-Efficacy And Gpa, Attendance, And College Student Retention, Stephen P. Becker, Robert K. Gable

NERA Conference Proceedings 2009

The study determined the extent and manner; self-efficacy explains variation in GPA, attendance, and retention. The General Self-Efficacy Scale was adapted with a sample of N = 194, 34% male and 66% female. General and Specific factors had alphas of .72 and .75, respectively. Step-wise regression demonstrated General self-efficacy incremented the explanation of GPA variance 5% (p < .01). GPA was significantly correlated with non-attendance (r = - .72, p < .01, d = large) and retention (r = .52, p < .01, d = large). Non-attendance significantly correlated with retention (r = -.39, p < .01, d = medium).

Database System Architecture For Fault Tolerance And Disaster Recovery, Anthony Nguyen

Regis University Student Publications (comprehensive collection)

Application systems being used today rely heavily on the availability of the database system. Disruption of database system can be damaging and catastrophic to the organization that depends on the availability of the database system for its business and service operations. To ensure business continuity under foreseeable and unforeseeable man-made or natural disasters, the database system has to be designed and built with fault tolerance and disaster recovery capabilities. This project explored existing technologies and solutions to design, build, and implement database system architecture for fault tolerance and disaster recovery using Oracle database software products. The project goal was to …

The Impact Of Tagging/Metadata Creation Exercises On College Freshmen’S Metacognitive Skills, Hilary Wilder

NERA Conference Proceedings 2009

Tagging is the process of specifying keywords, categories, and other identifying information for online informational and creative pieces such as photos, audio clips, video clips and text pages so that it can be searched for and located by others as well as semantically connected to similar objects on the Web. It was hypothesized that the repeated process of tagging objects and then receiving feedback from peers who try to use the tags to select the correct object as part of an online game-like activity would lead to improved epistemological skills.

Examining The Challenges Of Teaching For Social Justice In Sarajevo, Brian Kirby Lanahan, Peter Mcdermott

NERA Conference Proceedings 2009

Social justice is a critical principle of democracy. Societies seeking to become democratic must infuse social justice issues into their schools. In this qualitative study the researchers examined the extent to which social justice is being taught in Sarajevo’s educational system. With only a few exceptions, the findings indicate that education in Sarajevo has not reformed since the 92-95 conflict. Instead, Sarajevo’s curriculum has become more fragmented and less multicultural, and its schools are not preparing children to think democratically and work for social justice. Unless educational reforms accelerate, there is a real danger that the country may return to …

Financial Planning For College: What Parents Do To Prepare, Catherine A. Manly, Ryan S. Wells

NERA Conference Proceedings 2009

This study explores reported parental financial college preparations and the amount parents have saved for college, with a goal of determining strategies used by different parents based on parental college aspirations and expectations for their child, as well as the highest reported parental and grandparental educational levels. Regression analysis indicates that parents' expectations, but not their aspirations, correspond to engagement in financial planning. Family education is strongly associated with taking some financial planning actions and the amount saved. The results may be helpful to those who are working to increase the effectiveness of disseminating college financial information to parents.

The Relationship Of Student Demographics To 10th Grade Mcas Test Anxiety, Peggy Mccaleb-Kahan, Rolfe Wenner

NERA Conference Proceedings 2009

The intensification of consequential testing situations is associated with an increase in anxiety among American students (Casbarro, 2005). Test anxiety can have negative effects on student test performance (Everson, Millsap, & Rodriguez, 1991). If test anxiety has the potential to decrease students’ test scores, it becomes a factor that can threaten the validity of any inferences drawn between test scores and student progress (Cizek & Burg, 2006).

There are several factors that relate closely to test anxiety (Cizek & Burg, 2006). Variables of key influence include gender, socioeconomic status, and teacher-manifested anxiety (Hembree, 1988). Another influence upon test anxiety is …

Available Classroom Supports For Students With Autism Spectrum Disorders In Public Schools, Cheryl A. Sandford

NERA Conference Proceedings 2009

A self-administered electronic survey and follow-up interviews were used to determine the quality, quantity and types of supports that are provided for students with autism spectrum disorders in a variety of public school settings nationwide. Quantitative and qualitative analyses were conducted to determine the effects of educators’ background, ongoing training and development activities, opinions and attitudes of educators on the supports available. Statistically and socially significant effects were found for a number of these characteristics. A need for increased and improved educator training in autism strategies was a prevalent theme throughout the data.

The Black-White Achievement Gap Amongst Struggling Readers: A Case Study Of Early Intervention Outcomes In Massachusetts, Emily Dexter, Jessica Simon

NERA Conference Proceedings 2009

A number of analyses of large data sets have suggested that the reading achievement gap between African American and White U.S. is negligible or small at school entry, but widens substantially during the school years because African American students show slower rates of growth in elementary and secondary school. Identifying when and why gaps occur, therefore, is a an important research endeavor. In addition, being able to predict which African American children are most likely to fall behind can contribute to efforts to close the achievement gap. This paper analyzes first grade and third grade data on African American and …

Behavioral And Academic Effects Of Skillstreaming The Adolescent For At-Risk Middle School Students, Amy Evans, Candice Stefanou

NERA Conference Proceedings 2009

Research links social skills deficits with academic failure. This study investigated whether socials skills training leads to improved social skills and academic achievement. Six middle school students, considered behaviorally at-risk, participated in a six-week social skills training intervention using Skillstreaming the Adolescent (Goldstein, McGinnis, Sprafkin, Gershaw, & Klein, 1997). Teacher and self-report measures and grades were collected at pre-intervention, mid, and end of intervention. Results showed significant differences in teacher ratings of the students’ cooperation but no achievement improvements. This study provides evidence that brief, targeted interventions may have positive effects on some aspects of social skills for at-risk students.

Parallel Reflections: The Interdisciplinary Process Of Co-Constructing Meaning, Martha J. Strickland, Jane B. Keat, Jane M. Wilburne, Beatrice Adera

NERA Conference Proceedings 2009

This paper reports the results of a study conducted by four teacher educators who represent four disciplines in education. The purpose was to understand how pre-service teacher reflections influenced teacher educator reflections within a course. Data collection methods included narrative and document review. Data analysis methods included multiple readings and discussions of individual portraits in search of answers to research questions. Findings include a parallel reflection model that illustrates a dynamic process that occurs within the dialogic space as student and professor thoughts and discourse are interwoven to make theory to practice connections, co-construct new knowledge and begin challenging existing …

Developing A Scale To Assess Self-Efficacy For Response To Intervention Practices In Schools, Susan K. Barnes, Melinda S. Burchard

NERA Conference Proceedings 2009

Response to Intervention (RTI) is an educational model required by the No Child Left Behind Act and the Individuals with Disabilities Education Act (IDEA). This multi-tiered approach integrates ongoing assessment of individual student progress with targeted instruction, a process previously reserved for students with special needs. Educators are required to use RTI to monitor all children, even those not identified for special services. Effective educators need training in selecting appropriate instruments and conducting accurate assessments. This presentation describes the development of a scale to measure self-efficacy of educators using RTI to better identify areas in which educators need additional support.

The Homework Debate: How Much Homework Is Helpful For Students To Acquire Mathematical Procedural Knowledge?, Nicholas D. Hartlep, Jacqueline Gosz

NERA Conference Proceedings 2009

The effects of using homework guides and homework logs on students’ abilities to solve word problems involving basic addition and subtraction facts were studied. Students received one of three versions of addition and subtraction timed tests once per week—every Friday—that focused on measuring automaticity of basic addition and subtraction facts. Thirty-one first-grade students participated in this action-research study. Students’ automaticity of basic addition and subtraction facts increased over the course of this study. Results indicated that homework guides positively affected student motivation to put forth more effort on homework. Additionally, word problems that involved basic subtraction facts appeared more difficult …

Validation Of A Reader Self Perception Scale (Rsps2) For Use In Grades 7 And Above, Steven A. Melnick, William A. Henk, Barbara A. Marinak

NERA Conference Proceedings 2009

Clearly, the attitudes, values, expectations, and beliefs that individuals possess about literacy will play a vital role in shaping their engagement with reading, writing, and other language processes. Grounded in Self-Efficacy Theory (Bandura, 1977, 1982; Schunk, 1984), the Reader Self Perception Scale Version 2 predicts that students take four basic factors into account when forming literacy self-perceptions: Progress, Observational Comparisons, Social Feedback, and Physiological States. Student response data (n=3,031 in grades 7-10) provides evidence of construct validity through a principal components analysis of the factor structure. Alpha reliabilities by factor are reported.
