African American Caregivers Of Children Affected By Hiv/Aids, Doris Cooper Wilbon Dec 2007

African American Caregivers Of Children Affected By Hiv/Aids, Doris Cooper Wilbon

College of Graduate Studies: Theses & Dissertations

The Human Immunodeficiency Disease (HIV) and Acquired Immunodeficiency Syndrome (AIDS) have reached an epidemic proportion in many African American communities. There is a significant amount of stigma and denial associated with HIV/AIDS in these communities, leaving people with minimal knowledge about this disease. Caretakers such as grandparents, other relatives, and foster parents take on the role of surrogate parents to these children who have lost one or both of their parents to HIV/AIDS. When family members, especially women, die from this disease leaving their offspring behind these children often experience various emotional and behavioral problems. A few of the children …

A Closed Form Solution For Multiple-Input Spike Based Adaptive Filters, Il Park, António R.C. Paiva, José C. Príncipe, John G. Harris Dec 2007

A Closed Form Solution For Multiple-Input Spike Based Adaptive Filters, Il Park, António R.C. Paiva, José C. Príncipe, John G. Harris

Electrical and Computer Engineering Faculty Research & Creative Works

Neurons are point process systems, in the sense that the inputs and output which are spike trains can be treated as point processes. System identification of a point process system has been studied mostly with single input. However, multiple input is required in many applications such as liquid state machines or neural prosthetics. We propose a simple multiple-input spike based adaptive filter which is based on an integrate-and-fire neuron model. The optimal closed solution is derived, and the performance is analyzed with respect to noise in various parameters and measurement. ©2007 IEEE.

Dangers Of Credulity: Mary Robinson And The Trope Of Victimization, Jeffrey Paul Kozee Dec 2007

Dangers Of Credulity: Mary Robinson And The Trope Of Victimization, Jeffrey Paul Kozee

College of Graduate Studies: Theses & Dissertations

A prodigious professional poet admired by Samuel Taylor Coleridge; a courtesan idealized for her unparalleled beauty; a famed actress and mistress to royalty known to live beyond her means in an era of exploding print culture: Mary Robinson found herself portrayed incongruously in motley of mediums. While the leading portrait artists of the day, Thomas Gainsborough, George Romney, and Sir Joshua Reynolds, were painting dazzling portraits of Mrs. Robinson, she found herself lampooned in the satirical cartoons of James Gillray and Thomas Rowlandson. The multifarious representations of Mary Robinson seem an apt commentary on her tumultuous life. Intriguing in their …

Impact Of No Child Left Behind Act Mandates On The Roles Of Paraprofessionals, Katherine Jane Coyne Dec 2007

Impact Of No Child Left Behind Act Mandates On The Roles Of Paraprofessionals, Katherine Jane Coyne

College of Graduate Studies: Theses & Dissertations

As more and more paraprofessionals are hired in order to maintain or achieve the required educational benchmarks, the need for researchers to explore the field of paraprofessionals has greatly increased. The No Child Left Behind (NCLB) mandates have brought about increased requirements and certification for all paraprofessionals. Although these mandates have undergone extensive study, very little research has been conducted on how paraprofessionals feel this legislation has impacted them. The use of paraprofessionals in classrooms has grown substantially in recent years. Paraprofessionals assume a variety of roles, both in classrooms and in schools, as well as in special education and …

Detecting Malicious Logic Through Structural Checking, Scott C. Smith, Jia Di Dec 2007

Detecting Malicious Logic Through Structural Checking, Scott C. Smith, Jia Di

Electrical and Computer Engineering Faculty Research & Creative Works

Hardware is just as susceptible as software to "hacker attacks", through inclusion of malicious logic; and the consequences of such an attack could be disastrous! the impact of software viruses has been felt, at one time or another, by the entire computerized world, through loss of productivity, loss of system resources or data, or mere inconvenience. However, the nature of malicious logic and defending against it is fundamentally different from its software counterpart. Malicious logic has the added dimension of not being removable once encapsulated in the system. This paper will identify hardware vulnerabilities and will outline an automated method, …

Development Of Effective Discipline Practices Of A Rural Georgia Elementary School, Laurie Hale Lewis Dec 2007

Development Of Effective Discipline Practices Of A Rural Georgia Elementary School, Laurie Hale Lewis

College of Graduate Studies: Theses & Dissertations

For U. S. schools, never had there been a crisis on the scale of what happened at the Columbine High School on April 20, 1999, when two students killed 12 students and one teacher, and injured 21 others before committing suicide (Barrios, 2001). Violence, or the threat of violence, has a direct impact on the quality of education provided and on the way teachers and students work together in the classroom (Winett, 1998). Welldisciplined, effective schools are not a product of chance; it takes administrators, teachers, students, and parents working together to provide an environment conducive to learning (Marzano & …

Examining The Implementation Of School-Wide Positive Discipline Intervention And Its Impact On Teacher Beliefs, Values And Practices, Isreal J. Collins Dec 2007

Examining The Implementation Of School-Wide Positive Discipline Intervention And Its Impact On Teacher Beliefs, Values And Practices, Isreal J. Collins

College of Graduate Studies: Theses & Dissertations

The frequent occurrence of negative student behaviors such as bulling, verbal abuse, and disrespect remain a key concern for teacher. Teachers report instances of simple disrespect, noncompliance, poor peer interactions, cursing, making fun of one another, grabbing, pushing and being of-task as common occurrences in their classrooms. Teachers are expected and required to manage student behavior through the implementation of a well designed classroom management plan. Student disruptions through negative behavior require constant alteration of their management plan, reducing instructional time, and leaving teachers with high levels of personal frustration and stress. School districts around the country have begun to …

Taking Text Too Seriously: Modern Textualism, Original Meaning, And The Case Of Amar's Bill Of Rights, William Michael Treanor Dec 2007

Taking Text Too Seriously: Modern Textualism, Original Meaning, And The Case Of Amar's Bill Of Rights, William Michael Treanor

Georgetown Law Faculty Publications and Other Works

Championed on the Supreme Court by Justices Scalia and Thomas and championed in academia most prominently by Professor Akhil Amar, textualism has in the past twenty years emerged as a leading school of constitutional interpretation. Textualists argue that the Constitution should be interpreted in accordance with its original public meaning and, in seeking that meaning, they closely parse the Constitution's words and grammar and the placement of clauses in the document. They have assumed that this close parsing recaptures original meaning, but, perhaps because it seems obviously correct, that assumption has neither been defended nor challenged. This article uses Professor …

A Coupled Fluid-Structure Model Of A Therapeutic Ultrasound Angioplasty Wire Waveguide, Graham Gavin, Finbar Dolan, M.S. Hashmi, Garrett Mcguinness Dec 2007

A Coupled Fluid-Structure Model Of A Therapeutic Ultrasound Angioplasty Wire Waveguide, Graham Gavin, Finbar Dolan, M.S. Hashmi, Garrett Mcguinness

Articles

Ultrasonic longitudinal displacements, delivered to the distal tips of small diameter wire waveguides, have been shown to be capable of disrupting complicated atherosclerotic plaques during vascular interventions. These ultrasonic displacements can disrupt plaques by direct contact ablation but also by pressure waves, associated cavitation and acoustic streaming developed in the surrounding blood and tissue cavities. The pressure waves developed within the arterial lumen appear to play a major role but are complex to predict as they are determined by the distal tip output of the wire waveguide (both displacement and frequency), the geometric features of the waveguide tip and the …

Multi-Order Neurons For Evolutionary Higher Order Clustering And Growth, Kiruthika Ramanathan, Sheng Uei Guan Dec 2007

Multi-Order Neurons For Evolutionary Higher Order Clustering And Growth, Kiruthika Ramanathan, Sheng Uei Guan

Research Collection School Of Computing and Information Systems

This letter proposes to use multiorder neurons for clustering irregularly shaped data arrangements. Multiorder neurons are an evolutionary extension of the use of higher-order neurons in clustering. Higher-order neurons parametrically model complex neuron shapes by replacing the classic synaptic weight by higher-order tensors. The multiorder neuron goes one step further and eliminates two problems associated with higher-order neurons. First, it uses evolutionary algorithms to select the best neuron order for a given problem. Second, it obtains more information about the underlying data distribution by identifying the correct order for a given cluster of patterns. Empirically we observed that when the …

Separate Adaptive Mechanisms For Controlling Trajectory And Final Position In Reaching, Robert A. Scheidt, Claude Ghez Dec 2007

Separate Adaptive Mechanisms For Controlling Trajectory And Final Position In Reaching, Robert A. Scheidt, Claude Ghez

Biomedical Engineering Faculty Research and Publications

We examined control of the hand's trajectory (direction and shape) and final equilibrium position in horizontal planar arm movements by quantifying transfer of learned visuomotor rotations between two tasks that required aiming the hand to the same spatial targets. In a trajectory-reversal task (“slicing”), the hand reversed direction within the target and returned to the origin. In a positioning task (“reaching”), subjects moved the hand to the target and held it there; cursor feedback was provided only after movement ended to isolate learning of final position from trajectory direction. We asked whether learning acquired in one task would transfer to …

Different Learned Coordinate Frames For Planning Trajectories And Final Positions In Reaching, Claude Ghez, Robert A. Scheidt, Hank Heijink Dec 2007

Different Learned Coordinate Frames For Planning Trajectories And Final Positions In Reaching, Claude Ghez, Robert A. Scheidt, Hank Heijink

Biomedical Engineering Faculty Research and Publications

We previously reported that the kinematics of reaching movements reflect the superimposition of two separate control mechanisms specifying the hand's spatial trajectory and its final equilibrium position. We now asked whether the brain maintains separate representations of the spatial goals for planning hand trajectory and final position. One group of subjects learned a 30° visuomotor rotation about the hand's starting point while performing a movement reversal task (“slicing”) in which they reversed direction at one target and terminated movement at another. This task required accuracy in acquiring a target mid-movement. A second group adapted while moving to—and stabilizing at—a single …

Prolonged Quadriceps Activity Following Imposed Hip Extension: A Neurophysiological Mechanism For Stiff-Knee Gait?, Michael D. Lewek, T. George Hornby, Yasin Y. Dhaher, Brian D. Schmit Dec 2007

Prolonged Quadriceps Activity Following Imposed Hip Extension: A Neurophysiological Mechanism For Stiff-Knee Gait?, Michael D. Lewek, T. George Hornby, Yasin Y. Dhaher, Brian D. Schmit

Biomedical Engineering Faculty Research and Publications

The biomechanical characteristics of stiff knee gait following neurological injury include decreased knee flexion velocity at toe-off, which may be due to exaggerated quadriceps activity. The neuromuscular mechanism underlying this abnormal activity is unclear, although hyperexcitable heteronymous reflexes may be a source of impaired coordination. The present study examines the contribution of reflex activity from hip flexors on knee extensors following stroke and its association with reduced swing-phase knee flexion during walking. Twelve individuals poststroke and six control subjects were positioned in supine on a Biodex dynamometer with the ankle and knee held in a static position. Isolated hip extension …
