Detection of Unique Tumor-Associated Proteins in the Urine of Patients with Transitional Cell Carcinoma by High Resolution Two-Dimensional Polyacrylamide Gel Electrophoresis

Robert David Lehman
A two-dimensional polyacrylamide gel electrophoretic technique was developed for the detection of unique tumor-associated proteins in urine of patients with transitional cell carcinoma (TCC) of the urinary bladder. This technique yielded high resolution of polypeptides in the urine of cancer patients. Urine was chosen as a source of tumor-associated components because the location of the tum or should release already solublized tum or substances in to the urine. Urinary proteins were concentrated and then analyzed...

David L. Timpy
A wavestaff system utilizing capacitance was developed to measure wave heights in the surf zone. Data were used to test the assumption that wave height decays linearly across the surf zone. The instrument system consisted of two wavestaffs and housing which contained the needed electronic circuits and a data recorder. Acceptable frequency response for waves of period greater than two seconds could not be obtained if sensor wires were greater than 0.35 mm in diameter....

The Effects of Function-Based Thinking on Teacher Selection of Interventions for Disruptive Student Behavior

Kimberly Yanek
Traditional approaches to addressing student misbehavior often involve the imposition of reactive and punitive consequences. Certain groups of students who engage in disruptive behavior experience a disproportionate amount of these punitive disciplinary responses. African American males are one such group. A growing body of research suggests that a need exists for more proactive and positive approaches to addressing student classroom misbehavior. One promising option is function-based thinking—a critical component of functional behavioral assessment. The present...

Training Effects of Adaptive Emotive Responses From Animated Agents in Simulated Environments

Enilda Jannet Romero-Hall
Humans are distinct from machines in their capacity to emote, stimulate, and express emotions. Because emotions play such an important role in human interactions, human-like agents used in pedagogical roles for simulation-based training should properly reflect emotions. Currently, research concerning the development of this type of agent focuses on basic agent interface characteristics, as well as character building qualities. However, human-like agents should provide emotion-like qualities that are clearly expressed, properly synchronized, and that simulate...

The Non-Cognitive Attributes of First-Year At-Risk Students Who Are Academically Successful and Retained at Old Dominion University

Tisha M. Paredes
With a decrease in state and federal funding, higher educational institutions need to focus on retaining students. However, student retention is a multifaceted problem that requires varied solutions. Traditional measures, or cognitive measures, of student success, such as pre-college knowledge (SAT and high school grade point average) have not explained how higher education institutions retained students, especially students who are considered at-risk. Since the nature of student retention is idiosyncratic, research needs to focus on...

An Appreciative Look: Examining the Development of Urban Youths' Civic Identity In and Out of the Social Studies Classroom

Wendy Elaine Scott
Current trends in the United States show a decline in voter participation and other forms of political engagement (Torney-Putra, Wilkenfeld, & Barber, 2008). There is further evidence to suggest that an understanding of civic knowledge and behaviors that represent civic participation is even more abysmal for urban students including students with low economic status and minority groups (Kahne, 2009; Torrey-Putra, 2001). However, traditional discourse around the gaps and deficits faced by urban students fail to...

The Effects of Cooperative Grouping Strategies and a Three-Level Evaluation Tool on Student Soft Skills Achievement and Satisfaction Within a Problem-Based Instructional Model in the Soft Sciences
